THE DELIVERY STATUS OF JUNO 20" PMTS AND THEIR PERFORMANCE Rong Zhao 1 (on behalf of JUNO collaboration) 1Sun Yat-Sen University zhaor25@mail2.sysu.edu.cn Abstract The Jiangmen Underground Neutrino Observatory (JUNO) [1] is a multi-purposed neutrino experiment currently under construction in South China. Due to its unprecedented requirement on the photocathode coverage rate in order to reach enough energy res- olution, totally 20k 20-inch photomultipliers (PMTs) will be de- ployed in the detector system, including 5k conventional Hama- matsu dynode PMTs(R12860) and 15k newly developed PMTs us- ing micro-channel plates (MCP-PMT) by North Night Vision Tech- nology (NNVT). The JUNO collaboration has developed a PMT mass testing system to characterize these PMTs and selected the qualified ones for the final installation. Up to now, we have re- ceived and completed the characterization of 5k Hamamatsu PMTs and 13.1k MCP-PMTs. In this poster, we will present the latest de- livery details and the performance results including the typical sin- gle photon-electron (SPE) waveform, SPE spectra of two types of PMTs, SPE resolution, photon detection efficiency(PDE) and dark count rate(DCR) etc. Introduction of JUNO Detector The JUNO central detector will be filled with liquid scintillator, about 15k 20"MCP-PMTs and 5k 20"Hamamatsu PMTs will be used to collect scintillation light and Cherenkov light; the geometry of JUNO detector and PMTs are shown in Figure 1. Figure 1:JUNO detector and geometry of Hamamatsu PMT and MCP-PMT PMT Delivery and Test Status By May 2020, 18k of the total 20k PMTs have been delivered to JUNO PMT storage site, the acceptance test of 15k PMTs have been finished and 5k MCP-PMTs have been potted, as illustrated in figure below. 13.1k delivered 10k tested 15k total 5k tested 5.3k potted HAMAMATSU DYNODE PMT NNVT MCP-PMT All of the delivered PMTs will experience a detailed visual check and electronic performance test before they are potted and finally installed into JUNO detector. PMT Testing System Two container PMT testing systems with electromagnetic shield- ing are currently used for mass acceptance tests[4]. Each of them consists of 36 individual drawers (see Figure 2). The PMT inside each drawer can be illuminated with a self-stabilized LED or a pico- second laser, both with 420 nm wavelength. Two PMT scanning stations [2][3] were built for characterization of whole PMT photo- cathode. It allows for the testing of individual PMTs in all relevant aspects by scanning the photocathode and identifying any poten- tial problems. Figure 2:The container PMT mass test system and PMT scanning station JUNO PMT Performance of tested PMTs The typical single photon electron waveform of Hamamatsu PMT and MCP-PMT is shown in Figure 3: 100 150 200 250 300 350 400 t[ns] 0 2 4 6 8 10 12 14 U[mV] 100 150 200 250 300 350 400 t[ns] 6 8 10 12 14 16 18 20 U[mV] Figure 3:typical SPE waveform and 2D waveforms of Hamamatsu and MCP-PMTs. left: wave- form of Hamamatsu PMT EA0419; right: waveform of MCP-PMT PA1707-1090 SPE charge spectrum of PMTs obtained by LED with low illumina- tion(average photon number µ ≤1 ) are shown in Figure 4: Figure 4:charge spectrum of PMTs. left: Hamatsu PMT EA0419 with gain=9.9E6 and µ = 0.16, 0.79; right: MCP-PMT PA1707-1090 with gain=1.04E7 and µ = 0.14, 0.84.

MYRIAD-EU has received funding from the European Union’s Horizon 2020 Research and Innovation Programme under Grant agreement ID: 101003276 Introduction MYRIAD-EU: Multi-hazard and sYstemic framework for enhancing Risk- Informed mAnagement and Decision-making in the EU Philip J. Ward, Marleen C. de Ruiter, Timothy Tiggeloven, Judith N. Claassen, Ruoying Dai While the last decade saw huge scientific advances in the understanding of natural hazard risk, most research and policy still address risk from a single-hazard, single-sector perspective not taking into account the interconnected reality of these events. MYRIAD-EU’s vision is to catalyse the paradigm shift required to move towards a multi-risk, multi-sector, systemic approach to risk assessment and management. To achieve this vision, the overall aim is that by the end of MYRIAD-EU policy-makers, decision-makers, and practitioners will be able to develop forward-looking disaster risk management pathways that assess trade-offs and synergies across sectors, hazards, and scales. The project will focus on five multi-scale Pilot regions, in which we aim to better understand indirect, interregional, and cross-sectoral risk within Europe. Through this project we aim to reduce risks together: please contact us if you are interested in collaboration. Work Packages The MYRIAD-EU project is centred around eight Work Packages (WP’s) summarized in Figure 1. Hazard Classes Geological Hydrological Climatological Biological Meteorological The following hazard classes are included in the project Pilots and Sectors The Pilots (see Fig.2) are selected to provide: a spread of different spatial scales, geographical locations, institutional settings across the EU; hazard ranges and hazard interrelation types (triggering, amplifying, consecutive, and compound). The key sectors that will be covered in MYRIAD- EU are: 1. infrastructure & transport 2. food & agriculture 3. ecosystems & forestry 4. energy 5. finance 6. tourism Partners Figure 1: Overview of MYRIAD-EU Work Packages (WPs) Figure 2: Overview of MYRIAD-EU Pilots #MYRIAD-EU Prof. Dr. Philip Ward philip.ward@vu.nl | poster |

Further thermo-mechanical tests with castables containing vanadium slag as the bonding phase. Different trials to extract the vanadium in a sustainable way Contact different slag suppliers for further comparison with current slag composition Ongoing work: • Strength decreases significantly when adding slag to the formulation but the reference is based on high alumina castables, rarely employed in industries • E and G modulus data do not display considerable deviation with the different amounts of slag • Vanadium reacts preferably with Mg, Al and Ca towards a stable phase after sintering and does not attack the alumina grains. Conclusion: Context: The steelmaking industry generates several by-products during the different stages of steel production. As a by-product, vanadium slag account for more than 60% of the world’s overall production. However, it is tough to find vanadium in its pure state as it occurs in combination with various minerals. Using secondary resources for refractory castables solves the issue of natural raw materials, reduces costs related to their extraction and processing, and is friendly to the environment. Figure 1.

SPHERE quality control and dataflow operations The first observing period Wolfgang Hummel, ESO, Data Management and Operations Division (DMO) SPHERE calibration plan Science templates One peculiarity of the SPHERE calibration plan are the science templates that generate in advance of the science data also calibration data valid for the particular pointing only. These include an optional image of the waffle pattern to reconstruct the source center behind the coronograph (called CENTER) , an optional source offset image for the flux calibration (called FLUX) and optional sky frames. Introduction Since April 2015 ESO operates the new planet finder instrument SPHERE (Fig. 1). SPHERE is one of the most complex instruments at the VLT. It consists of the common path and infrastructure (CPI) for AO and coronography and of three arms: IRDIS, IFS and ZIMPOL. A total of eight different observing modes is supported, each one with its own independent calibration plan and data association scheme. The modes include NIR differential beam imaging, integral field spectroscopy and differential polarimetric imaging with 30msec time resolution in the visual. [1] The first observing period of an instrument is usually the most critical phase in its life time, in particular in the context of quality control (QC) which is a task shared between science operations on site and the QC group in Garching. Here we report on the data flow design challenges, the QC system and operational highlights of the first six months of SPHERE operations. Operational Highlights: IFS light leakage We found a light leakage in the IFS-arm detector. As a consequence the dark calibrations show: The dark current is linear function of DIT (Fig. 4, Box 4). The dark current depends on the temperature at the optical bench (Fig. 4, Box 6). The statistical noise measured is dominated by the shot noise introduced by the light leakage (and not by the readout noise ~3 ADU) The statistical noise scales as square root with DIT (Fig.5, Box 4) ACKNOWLEDGEMENTS/REFERENCES Narrow band - broad band filter match The time to acquire day-time calibrations scales with the number of different instrument setups the observations use in one night, but the time window for taking day-time calibrations is confined due to operational reasons. Since it is justified for IRDIS and ZIMPOL to calibrate narrow band filter science observations with broad band filter day- time calibrations (covering the narrow band), this filter association was implemented for reasons to make use of these synergies.

Ecological data: design, management, and processing. Oxford: Blackwell Science. Key Campus Unit Stakeholders • Research Data Services (RDS): Interdisciplinary organization committed to advancing research data management practice on the UW-Madison campus. • University of Wisconsin-Madison Center for Limnology (CFL): Research center dedicated to the study of fresh-water ecosystems and ecology programs, houses graduate students from zoology, ecology, and engineering. Problem: Research Data Literacy Graduate students from the University of Wisconsin Center for Limnology were awarded a grant funding from Integrative Graduate Education and Research Traineeship (IGERT) to host a research data management education workshop for graduate colleagues. Although data are used frequently by the graduate student group, sound data management practices and a thorough understanding of the importance of data stewardship are still challenges. Implication Facilitation Organization Conception Proposal Initial development of the workshop was proposed to RDS by graduate student leaders from CFL in late spring 2014. RDS subsequently identified four of its own members to lead and plan the workshop. Focus on ecology Data management practices in limnology share a considerable number of similarities with ecology. The planning stage of the workshop focused on collecting information about discipline and data workflow characteristics of ecology from published resources, conversations about the importance of teaching certain topics, and the graduate students’ own personal beliefs and values associated with data management which were collected by survey prior to the proposal. Needs One meeting with CFL graduate student leaders allowed RDS leads to gather support and input about attendee needs. Subsequent regular emails were sent to CFL leaders and audience members to gather more information about data management barriers and challenges. Objectives RDS leads identified three objectives for the audience: 1) Increase awareness about RDS services 2) Expand data management proficiency with module content 3) Build understanding of complete data management workflow Module topics and organization Based on models of ecological data workflows, topics selected and organized into a two-day workshop format. Day One (10am-4pm): Intro to RDS, spreadsheets, metadata, storage, file organization, and sharing Day Two (10am-12:30pm): Preservation and data management plans Hands-on work time was initially built into each module Instructor selection The planning team chose several instructors from departments affiliated with Research Data Services who are likely to train future researchers on campus. Also chosen were instructors from ecology-associated departments who are likely to influence data management education for ecologists. Realized module workflow Due to instructor schedules, and content overlap workshop modules were reorganized thusly: Day One (10am-2pm), November 10, 2014: Intro to RDS, spreadsheets, file organization & collaboration, and time allotted at end for collaborative work time Day Two (9am-12:30pm), November 11, 2014: Storage & preservation, data management plans, scholar presentation on ecology data management research Activities Since hands-on activities were not practical for modules on the second day, time was allotted at the end of Day One to allow audience members to work with each other and instructors to garner feedback about data ma | poster |
Statistics of annotated validation dataset. Statistics of annotated validation dataset. The preliminary results of using Point Transformer trained on a public 3DEP point cloud classification dataset are promising. BACKGROUND: The USGS 3D Elevation Program (3DEP) is collecting lidar point data for the entire continental U.S. Minimum classification is following for current 3DEP. Accurately classified point clouds can support many down-stream applications such as in hydrologic analysis, urban planning, and forest management. This project will employ proven Deep Learning (DL) technologies in the development of a user-friendly open-source toolkit that will automate point cloud classification to refine and enrich the attributes of existing and future 3DEP data.

(1) Xi’An Jiaotong-Liverpool University ; (2) Leiden university; (3) Chinese Academy of Sciences; (4) Kavli Institute for Astronomy and Astrophysics at Peking University; (5) Zentrum für Astronomie der Universität Heidelberg Abstract Most stars in the Galaxy form in stellar groupings that either dissolve within several tens of millions of years, or evolve into open clusters. It is important to study the dynamics of planetary systems in such structures to explain the properties of observed exoplanets. Here, we numerically evolve open star clusters with planetary systems by combining the star cluster code NBODY6++GPU code with the planetary system code REBOUND. We use different sets of initial conditions, such as the virial ratio and stellar density, and evolve the system for 50 Myr. We find that stellar encounter properties, the star cluster density, and the planetary system architecture are the main factors that affect the evolution of the planetary systems. Although most planetary systems remain intact, others lose most of their outer planets, while some are stripped of all planets. Finally, we find that the presence of the planet Jupiter plays a prominent role in the survival chances of terrestrial planets.

Most planetary system remain stable during the whole simulation, while most of the unstable one have ejected the outermost planets. The terrestrial planets are ejected mostly if Jupiter orbits gets perturbed, and it is completely destroyed with a impulsive encounter[8] . In the presence of a encounter, Jupiter acts both as dynamical barrier for weak encounters and as a perturber for the terrestrial planet for stronger encounters-. The final architecture of planets can be seen in the table, where the 1 and 2 planetary system are always, for all simulation and initial conditions, Jupiter for the 1 planet Solar system and Jupiter and Saturn for the 2 planet Solar system. The three planets scenario is unlikely for the empirical consequence of the Saturn presence in the 2-planets system. Black holes have also shown to impact the ejection of planets from their stellar systems[10]. Methodology We use REBOUND[2 ] as integrator for planetary systems and NBODY6++GPU [3] for the star cluster in order to model the gravitational dynamics, via N-Body codes, of both. The latter is using a C code environment, also working along with Python, optimised for few-body integrations, while the last is optimised for highly accurate and fast calculation and also supports MPI and GPU implementations, built for many-body integrations. We used 50 Myr as an evolutionary time, while 1000 years is the time-step for the star cluster output. The planetary output time-step is adaptive, and reproduces the previous 1000 years time-steps in the data storage, while it warns the user if the planets either escape or merge during this period (in short block time storage[4] ). We use the HDF5 format, which allows us to store data with high temporal resolution.[5] Finally the simulation can be resumed in 3 principal steps: star cluster and planetary system initial conditions, stars gravitational evolution with the nearby stars and plane | poster |

UNIVERSITY OF LEEDS Results III The basic Microscale Model has been extended to include moist dynamics - including the contribution from latent heat exchange Exploring a cut-cell representation of terrain in a microscale model Abstract Moves to increasingly high-resolution models give rise to more variations in the underlying orography being captured by the model grid. Consequently, high-resolution models must overcome instabilities associated with terrain-following (see Fig. 1a) approaches. This work further explores the capabilities of a cut-cell representation of orography for idealised orographically-forced and moist microscale flows. The model is based on terrain-intersecting coordinates (see Fig. 1b) and solves flow in the resulting cut-cells using a finite-volume approximation. The model has been designed for the purposes of very high-resolution simulations. Comparisons with benchmark orographic and moist test cases demonstrate very good results. Further tests show the potential for the cut-cell approach for stably resolving flows over very steep orography. Institute for Climate & Atmospheric Science SCHOOL OF EARTH AND ENVIRONMENT, UNIVERSITY OF LEEDS S. Lock, A. Coals, A. Gadian, S. Mobbs Microscale Model is a research model for very high-resolution studies - of grid-resolutions x ~ z < 100m. The project has focussed particularly on flows over steep and complex terrain. The model is 3- dimensional, nonhydrostatic and fully compressible, with prognostic variables u,v,w,’,’. Integration is computed with a time-splitting approach (based on Klemp & Wilhelmson, 1978) using 2nd-order leapfrog for the long timestep and a 1st-order forward-backward scheme for the short step. A 2nd-order centred scheme is used for spatial differencing on a staggered grid (Arakawa-C in the horizontal, Charney-Phillips in the vertical). The orographic surface is represented by a piecewise bilinear function, and a finite-volume approach is used to solve flows through the resulting cut-cells. Background Cut-cells were first explored in environmental modelling by Marshall et al. (1997) for representing ocean-bottom topography. Results showed a piecewise linear representation of the surface compared favourably with step representations, particularly for surfaces that show large variation at the grid-resolution. The cut-cell work was extended to a compressible atmospheric model by Bonaventura (2000) and results were seen to compare well with a traditional terrain-following model. Steppeler et al. (2002, 2006) further extended the work, implementing a 3D piecewise bilinear representation of orography in a full atmospheric model (COSMO-DE). Tests showed good comparison with the equivalent terrain-following model, and studies of real cases showed evidence of improved precipitation forecasts from the cut-cell approach. Model equations describe a 3D, nonhydrostatic, fully compressible system. Written in time-split form, with fast modes (acoustic and gravity) on the LHS and slow modes on the RHS, the equations take the form: Cut-cell approach is based on the method discussed in Steppeler et al. (2002, 2006). The orographic surface is represented by continuous piecewise bilinear surfaces, that intersect the model grid – Fig. 2. The orographic surface results in some cells that are cut – partially beneath the surface; partially above. Flow through the cut-cells is solved by Fig. 1: Vertical levels in (a) a terrain-following, and (b) a terrain-intersecting grid a) b) Fig. 2: Example orographic surface intersecting a grid- column, from Steppeler et al.

Justification: I/O can represent a bottleneck in many applications . This bottleneck can be addressed by facilitating use of fast but expensive storage media in an hierarchical architecture. The use of storage-class memory additionally to spinning disks blurs the line between byte addressable and block data store Unique Features: • Containers for treating many objects the same • Distributed Transaction Management • Supports global memory abstraction • Integrated AI framework • Function shipping to move processing to the data • Data Aware Scheduling based on SLURM • QoS based Architecture Global Memory Abstraction: applications, tools and programming models access data on the SAGE system either directly by mapping objects to memory in the tier nodes, or, by accessing them as a storage system through the Clovis API. Three scenarios envisaged: • Make NVRAM-C (NVRAM within compute nodea) appear as a single addressable space • For larger objects, make use of external NVRAM (NVRAM-E), directly accessing using RDMA • Using standard MERO APIs to access data in any tier Under Development: • Differential checkpointing of objects to back them up to lower level storage • Data Reshaping to allow restart with different numbers of nodes Co-Design: SAGE architecture has been co-designed with application developers and users.

Optofluidic Force Induction Scheme for the Characterization of Nanoparticle Ensembles Marko Šimić,a,b Gerhard Prossliner,b,c Ruth Prassl,c Christian Hill,b,c Ulrich Hohenestera a Institute of Physics, University of Graz, Austria; b Brave Analytics GmbH, Austria; c Gottfried Schatz Research Center, Division of Biophysics, Medical University of Graz, Austria Abstract Momentum transfer from light to matter provides the basic principle of optical tweezers. Most studies have hitherto employed this principle for trapping and manipulation of single nanoparticles. However, in a microfluidic channel one can also monitor the effect of optical forces exerted on ensembles of dielectric nanoparticles, to acquire knowledge about various nanoparticle parameters, such as size, shape or material distributions. Here, we present an optofluidic force induction scheme (OF2i) for real-time, on-line optical characterization of nanoparticles. Our experimental setup builds on precisely controlled fluidics as well as optical elements, in combination with a focused laser beam with orbital angular momentum. By monitoring the single particle light scattering and trajectories in presence of optical and fluidic forces, we obtain detailed information about the properties of the individually tracked particles. We analyse the trajectories using a detailed simulation approach based on Maxwell’s equations and Mie’s theory, in combination with laser fields and fluidic forces. We discuss the basic physical principles underlying the OF2i scheme and demonstrate its applicability. Our results prove that OF2i provides a flexible work bench for numerous applications. Introduction Here we employ optofluidic forces on ensembles of nanoparticles using a laser tuned at 532 nm with precise micro-fluidic pumps. Both, optical and fluidic components generate forces acting on dielectric nanoparticles as shown in figure and . Under certain conditions, particles are constrained to a 2D-optical trap and travel along characteristic trajectories, see figure . Single-particle trajectories shown in are processed in real-time by recording single particle light scattering via an ultramicroscope setup and a CMOS camera. References [1] Ashkin A.

The time-averaged optical forces are computed by where is Maxwell’s Stress Tensor. The integration is performed using the total fields and a Gauss- Legendre quadrature for spherical particles with and being material constants. Results The experimental data for 400 nm Standard-Latex particles is compared to simulated velocities and depicted in figure . The resulting size distributions are shown in figure for mono- and polydisperse samples. We compare our results to those of Nanoparticle Tracking Analysis (NTA). Discussion The OF2i scheme is presented with its underlying physical principles together with a theoretical description based on Mie’s theory and higher order Laguerre-Gaussian modes. Our results show very good agreement between experimental and theoretical data on the example of various standardized Latex particles. Furthermore, we prove the working principle of OF2i and demonstrate its applicability to various nanoparticles. Simulations We now combine Newton’s equation of motion with Stokes’ drag and obtain for the particle’s velocity at any position within the capillary. Integrating particle velocity, we obtain the corresponding trajectory using a Runge-Kutta scheme. Figure shows selected trajectories for 200 nm, 400 nm, 600 nm and 900 nm using above’s | poster |

We fBLS is well suited to the analysis of PLATO lightcurves. We currently adapt fBLS and extend its operation to efficiently detect currently adapt fBLS and extend its operation to efficiently detect planets with varying transit duration and timing [4]. planets with varying transit duration and timing [4]. We used fBLS We used fBLS to detect small rocky transiting planets with to detect small rocky transiting planets with periods shorter than one day, a period range for which the periods shorter than one day, a period range for which the computation is extensive [3]. We have discovered five new planet computation is extensive [3]. We have discovered five new planet candidates (Shahaf et al., in prep.) candidates (Shahaf et al., in prep.) For a given lightcurve of measurements, fBLS simultaneously produces binned and phase-folded lightcurves for an array of ‘sufficiently different’ trial periods, with arithmetic operations. This procedure is conceptually similar to FFT. For comparison, a standard BLS implementation requires operations. For each folded lightcurve we compute the BLS statistic [5], producing a standard BLS periodogram. Demonstration: Kepler-78b Figure 1: fBLS periodogram of Kepler-78. The left panel is a grayscale diagram demonstrating the fast-folding algorithm output for a narrow frequency range centered around the periodogram peak. The fBLS periodogram appears on the Right panel, where the BLS scores were calculated for each of the fast-folded profiles. The central peak is highlighted in yellow. The required single-core computation time for the settings used in this example is ~10 sec. Ultra-short period (USP) planets are exoplanets with orbital periods shorter than one day, which tend to be terrestrial.

Input data were extracted from “The Catalogue of Galaxy Clusters and Groups” (Panko & Flin, 2006). Main type of substructures is linear elongated overdence regions in the cluster field. The direction of the linear substructure points usually to the nearest neighbor. In additional we found X- or Y- type regular substructures as well as short and/or compact chains. Bright galaxies in clusters are located in the regular substructures mainly and galaxies in the chains also show significant alignment along the chain. Founded peculiarities can be considered as a result of the formation of galaxy cluster at the intersection of DM filaments or filament-wall interaction.

Research Data Management Service Sustainability Tina Griffin, MLIS. Asst. Professor. University of Illinois Chicago. Chicago, IL 60612 Margaret Janz. Interpreter II. Great Parks of Hamilton County. Cincinnati, OH 54231 Introduction Libraries at high-level research and other academic institutions have been involved in research data management service (RDMS) for more than ten years. As the demand for these services has increased, libraries have adapted their service models. There have been several studies that have reviewed the “state of RDM services,” but these have only provided a snapshot of activities at a given time. Research Data Management activities require support through infrastructure, personnel, time, and money. Previous studies address these topics individually, but there is little connection between RDMS data collected over time and are few longitudinal studies. These studies also do not address the necessary decisions and changes that must have been made to make RDMS sustainable over time. This study will attempt to fill that gap by updating the RDMS status to describe the current baseline, broadening the facets addressed so that details about sustainability can be highlighted, and presenting the data by cohort to help other institutions identify parallels to their RDMS. Methodology • A 62-question survey was distributed in the fall of 2020 for 6 weeks through data listservs and message boards (DataCure Google Group, Research Data Access and Preservation discussion forum, International Association for Social Science Information Service and Technology listserv, Digital Library Federation listserv, Research Data Alliance forums). Two reminders were sent, one at 3 weeks and one the day before close. • Questions asked about changes in service model, staffing and funding, accountability, and planning for research data management services since service inception. • The survey was reviewed by eight data librarians currently in the field, and edited for bias, errors, and clarity. A copy of he survey instrument can be downloaded here: https://go.library.uic.edu/RDMSUSurveyInstrument. • IRB at both authors’ institutions reviewed the protocol and it was determined to be exempt. • The survey data was collected via Qualtrics Survey Software (Qualtrics, LLC. Provo, UT, USA. https://www.qualtrics.com/). • Received 118 responses. 70 responses were analyzed, including 32 which were partially complete. • Responses were excluded if: • did not contain any data (21) • only answered the question regarding service duration (9) • services were offered less than one year (16) • did not consent (2) • Personally identifying and some institutional demographic information was deleted before analysis, as per the informed consent agreement.

SLSTR will retrieve global coverage sea surface skin temperature (SSTskin) with zero bias and an uncertainty of ± 0.3 K (1σ) for a 5 x 5 degree latitude longitude area, having a temporal stability of 0.1 K/decade in support of Copernicus climate monitoring and operational Numerical Ocean/Weather Prediction (NOP/NWP) applications. In addition, SLSTR using a suite of visible and infrared radiance measurements, monitoring, ice surface temperature, cloud imagery, atmospheric aerosol, land, forestry and hydrology products in support of Copernicus serviceswill provide land surface temperature, active fire. This poster presentation presents initial results from the Sentinel-3A SLSTR as of May 25th 2016. C. Donlon, D. Smith (RAL), B. Berruti, J. Nieke and J. Frerick.

Additional channels at 1.378 µm and 2.25 µm are included to enhance thin cirrus cloud detection. SLSTR has an additional capability to derive active fire measurements using an extended dynamic range of the 3.7 µm channel and dedicated optimized detectors at 10.8 µm that are capable of detecting fires at ~450 K without saturation. è SLSTR uses two independent scan chains each including a separate scan mirror (scanning at a constant velocity of 180 rpm), an off-axis paraboloid mirror, and a fold mirror to focus measured radiance into the instrument Detector Assembly (DA). An innovative recombination “flip” mirror alternately relays each of the scanned optical beams into a common field plane at the entrance of the DA where there is a cold baffle. ç While more complex than the single scan system employed by the (A)ATSR instrument series, the SLSTR 3-mirror scan configuration increases the instrument oblique view swath to ~750 km (centred at the SLSTR nadir point) and the nadir swath to~1400 km (offset in a westerly direction). The nadir swath is asymmetrical with respect to the nadir point to provide identical and contemporaneous coverage with OLCI ocean/land colour measurements. Visible and short-wave infrared detectors have a spatial resolution of 0.5 km on ground. Thermal infrared detectors have a spatial resolution of 1 km on ground. 05/04/2016 10:02 am. The first image from the Sentinel-3A SLSTR thermal-infrared channels at 1km spatial resolution reveals thermal signatures over a part of western Namibia and the South Atlantic Ocean. Cold water is seen along the Namibian coast upwelling from deeper waters. The Benguela current flows north along the west coast of South Africa driven by southeasterly winds, creating coastal upwelling. Many eddies and meanders are generated in this complex system and these small-scale features are captured beautifully. Over land, the distinct folds of desert dunes can be seen.

The public codes ASOHF and VORTEX for the post-processing of cosmological simulations David Vallés-Pérez 1,† Susana Planelles 1,2 Vicent Quilis 1,2 1Departament d'Astronomia i Astrofísica, Universitat de València 2Observatori Astronòmic, Universitat de València †david.valles-perez@uv.es ASOHF (Vallés-Pérez, Planelles & Quilis, 2022) ASOHF is an adaptive spherical overdensity DM halo finder and galaxy finder. Among its main features, we can count: Haloes are detected from density peaks in configuration space. Dynamical information is subsequently used through several complementary unbinding processes. Physically motivated, self-consistent definition of substructures (see below). Possibility to look for galaxies within DM haloes (see below). Complete merger trees, robust to the loss of haloes in a number of snapshots. Outputs include lists of haloes with several (∼50) properties and, optionally, complete member particle lists. Python packages provided. Optimal scaling properties, ∆twall ∼Npart/ncores in shared-memory platforms (OMP) and low memory footprint. Does not require external, special libraries to be installed. Parallelisation (beyond OMP) Large (≳50 Mpc) simulations with many (≳109) particles can benefit from the domain decompo- sition strategy, which is performed externally to the code. Different subdomains can be run con- currently or sequentially, and the different domain outputs are seamlessly merged afterwards. Substructure Substructures are delimited by their Jacobi radius, RJ, encompassing the region more bound to the satellite than to the host halo. This is usually a more restrictive definition than others based on the density profile alone. Galaxy finder Galaxies are looked for within DM (sub)haloes us- ing a variation of the SO method, and are finally characterised as fully independent objects (with different centre, bulk velocity, etc.). Galaxy ex- tents are delimited by density and density gradi- ent, in addition to phase space arguments.

I-а Міжнародна конференція «Відкрита наука та інновації в Україні 2022», Київ, 27-28 жовтня 2022 р. UNIVERSAL MURANOV ENGINE WITH EXTERNAL HEAT EXCHANGE FOR ENVIRONMENTALLY FRIENDLY GENERATION OF CHEAP ENERGY Muranov Sergey, Muranov Ivan e-mail: smuranov111@gmail.com; tel. +38 050 819 82 10 One of the most important economic problems are : reducing the cost of energy, reducing the consumption of hydrocarbon raw materials, as well as switching to more efficient, reliable and environmentally friendly methods of energy generation Investors are offered an innovative project engine Universal Muranov Engine (UME) that radically reduces the cost of electricity generation (by 2-3 times) while improving environmental friendliness This engine is a deep modernization of the Stirling engine (SE) Matrix SWOT a Stsrling Engine (operating engines in USA, China, Sweden…) + Strength SE: unique properties for efficient power generation high efficiency, the ability to run on any type of fuel and from any external heat sources, noiselessness; - Weakness SE: high manufacturing cost; bulkiness of construction, heavy weight. + Opportunities SE: a wide range of applications, in particular in distributive power generation systems in cogeneration plants. - Threats SE: limitation of the scope of application due to high cost, large dimensions and weight. reduced SE reliability due to the complexity of the mechanical drive design. Universal Muranov Engine (UME) The upgraded Stirling Engine designated as the Universal Muranov Engine with external heat exchange, developed by S. Muranov and I. Muranov, can be the basis of a new highly efficient, reliable and environmentally cleaner energy. The deep modernization of the SE included: development of a crankless mechanism built exclusively on rolling bearings; a unique system for heat recovery from the walls of the working cylinder, a system of reliable seals of pistons operating without lubrication, a new efficient system of heat exchangers with a small dead space. During the modernization, significant shortcomings of the SE were overcome, the cost of manufacturing the engine was radically reduced, efficiency and reliability of operation were increased, the weight and dimensions of the engine were significantly reduced, expanded application areas. The upgraded new UME is able to compete with internal combustion engines. and also with gas and steam turbines in terms of application efficiency. At the same time, UME-based mini-CHP plants generate energy and heat 2-3 times cheaper than traditional power plants. This engine can also be used on any vehicles - cars, ships, yachts, submarines, etc. UME can work autonomously for a long time without any maintenance. The modularity of the design allows you to create engines with a power of 1-50 MW. This project is also of exceptional importance for the EU and Germany, due to the fact that it radically reduces the cost of electricity, reduces the need for hydrocarbons, contributes to the preservation of the environment, and also increases the competitiveness of industry, energy independence and economic efficiency. The project was developed and tested for operability in the 3D design system of SolidWorks. All the main nodes have a novelty at the world level and will be patented. Individual nodes were tested on full- size real samples. An investor is required to finance the prototype. | poster |

TOI 560 : Two Transiting Planets Orbiting a K Dwarf Validated with iSHELL, PFS and HIRES RVs Mohammed El Mufti1, Peter Plavchan1, Angelle Tanner2, Eric Gaidos3, Bryson Cale4, Michael Reefe1, Justin Wittrock1, Kevin Issac Collins1, Patrick Newman1, David James Vermilion1,5, Claire Geneser2, Rena Lee3, Ahmad Sohani2, Farzaneh Zohrabi6 George Mason University1, Mississippi State University2, University of Hawai‘i at Mänoa3, NASA JPL4, NASA Godard Center5, Louisiana State University6 Abstract We validate the presence of a two-planet system orbiting the 0.15–1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system con- sists of an inner moderately eccentric transiting mini-Neptune (TOI 560 b, P = 6.397438 ± 0.000037 days, e = 0.294+0.13 −0.062) initially discovered in the Sector 8 mission observations, and a transiting mini-Neptune (TOI 560 c, P = 18.8779 ± 0.0016 days) discovered in the Sector 34 observations, in a rare 1:3 orbital resonance. We utilize photometric data from Spitzer, and ground-based follow-up observations to confirm the ephemerides and period of the transiting planets and vet false positive scenarios. We obtain follow-up spectroscopy and corresponding precise radial velocities (RVs) with the iSHELL spectrograph at the NASA Infrared Telescope Facility and the HIRES Spectrograph at Keck Observatory to validate the plan- etary nature of these signals, which we combine with published PFS RVs from Magellan Observatory. We place upper limits on the masses of both planets of <2.1 and <4.1 MNep for b and c, respectively. We apply a Gaussian Processes (GP) model to the light curves to place priors on a chromatic radial velocity GP model to constrain the stellar activity of the TOI 560 host star. TOI 560 is a nearby moderately young multi-planet sys- tem with two planets suitable for atmospheric characterization with James Webb Space Telescope (JWST) and other upcom- ing missions. pychell Data Pipeline When star light passes through our gas cell and iSHELL cross-dispersed echelle spectrograph, we obtain high-resolution (R=80k) multi-order spectra. For each of the 29 orders, we do optimal spectral extraction (weighted summation) in the verti- cal direction so that in each column eventually we get a single value, which gives us a 1D spectrum for each order. We then forward model the spectrum to measure the radial velocity for each order, and then co-add the RVs from each order. We an- alyze our extracted spectral data using the following standard forward model where each term is a function of wave- length: Intensity = Blaze Function ×(Star × Gas Cell × Tellurics) ⊗Line Spread Function The blaze function ultimately sets the continuum of our spec- trum. The line spread function effectively blurs the spectrum down to resolution of the iSHELL spectrograph. The star has a Doppler shift, and the gas cell also has a Doppler shift which enables us to calibrate for instrumental drift in the wavelength solution and to constrain the line spread function. The tel- lurics, parameterized by a scaling factor optical depth related to airmass, are the remaining lines that causes by the green- house gases in the Earth’s atmosphere. Our RV pipeline is adapted from the CSHELL RV code de- scribed in [1]. We have rewritten the CSHELL code in a Python script pychell to adapt to iSHELL’s larger spectral grasp with multiple orders [2].

www.helmholtz-hzi.de Introduction The species of the Chaetosphaeriaceae (Chaetosphaeriales, Sordariomycetes, Ascomycota) are microscopic asexually reproducing fungi, some of which belong to the life cycle of sexual morphs with macroscopic fruit bodies (~300 μm diam) perceptible as “black dots” on the surface of decaying plants. They are invisible to most of the people and difficult to find even by a trained eye. In addition, they are usually hard to cultivate and slow growing, what make them difficult to study. Traditionally, they are reported from the decaying plant matter in the forest habitat and some exhibit endophytic lifestyle . Surprisingly, analysis of metabarcoding data showed that they are also common soil fungi, dwelling in a bulk soil in grasslands and croplands. There are about 44 genera classified into this family with monographs available for several genera, but with very little knowledge about their biology. Studies showed that Chaetosphaeriaceae members are important degraders of lignocellulose in wood, litter and soil and have rich structural diversity of natural compounds (e.g. terpenoids, cyclic peptides, naphthoquinones, lactones, lipopeptides, xanthones). Three unpublished and unannotated draft genomes of Chaetosphaeriaceae are available (1000 fungal genome project). Nevertheless, the information about the genetic background of the basic pathways is missing in this fungal lineage. The same is true for the whole Chaetosphaeriales. Our study is filling this gap using analysis of genomes from 16 species. Genome assembly statics of 16 species from the family Chaetosphaeriaceae Comparison of CAZymes classes within the Chaetosphaeriaceae Homology analysis of predicted pyrichalasin H biosynthesis gene cluster in M. ciliata, M. caesia, and P.grisea Conclusion: In this study, we introduced the genomes of sixteen Chaetosphaeriaceae species. The quality of those genomes were assessed, and their carbohydrate-active enzymes (CAZymes) were annotated. There are more than 800 genes that encode CAZymes from each species. The genome mining of the analyzed members of the Chaetosphaeriaceae species revealed a high diversity of biosynthetic pathways that far outmatches the number of compounds known from the individual species. The genome sequences generated in this work will enablea broad range of investigations including studies on fungal evolution, population dynamics, biodegradation and also biosynthesis of secondary metabolites.

Abstract Organic ligands have been used to modify the surface charge in nanochannels formed in cellulose and anodised aluminium oxide (AAO) membranes, using a combination of oxidative, covalent and non-covalent chemistry approaches. Initial electrical and thermoelectric measurements performed on the membranes show that surface functionalisation enhances ionic thermoelectric effects in these nanochannels. 3.

Future Work • Improvements to this study • Larger sample sizes • Vary populations, especially to avoid selection biases • What is the mechanism for the improvement in self-efficacy? Is it sustained long-term? • Hypothesis: Focusing on future impacts enables students to envision themselves as active participants in a changing world. • Can we use our students’ desires to increase motivation and self-efficacy? • E.g. describe how the concepts they’re learning have impacted the world today and/or how these concepts can be leveraged to change the future Experimental Design 1. Pre-class questionnaire. The survey contained SMQII likert-type questions to assess motivation and open-ended questions to investigate student preferences about learning about scientific research. 2. Brief lecture. Students were introduced to historic examples of the impacts of research on society through machine learning as it relates to Netflix recommendations. The areas of scientific impact were then presented. This process served to: i. introduce the concept that scientific research has real-world consequences ii. demonstrate a framework for evaluating the broader impacts of research. 3. Think-pair-share. A problem situated discussion in either the influence of past research on the world today (intervention A) or how current research might impact the future (intervention B). 4. Post-class questionnaire. This survey utilized re-worded, but equivalent, SMQII questions to assess motivation to learn science, and open-ended questions to gauge changes in perceptions of science classes and scientific research. The pre- and post- class questionnaires contained unique codes that link answers to a particular student without revealing identifying information. Results Conclusions • Students indicate that they prefer to learn about current scientific research. • Open-ended responses can be categorized into specific desires. • Students who experienced intervention B, where discussion was grounded in the future impacts of current scientific research, reported an overall increase in self-efficacy, as measured using questions from the SMQII. • Wilcoxon signed-rank test between pre- and post-intervention scores for individuals is significant (p-value = 0.0003049) • This suggests that even quick, one-time interventions can produce measurable changes in self-efficacy The effects of temporal focus on students’ motivation to learn science James C. Schwabacher1 1Northwestern University, Evanston, IL 60208 Motivation in Social Cognitive Theory The motivation to learn science is “an internal state that arouses, directs, and sustains science-learning behavior,” and is typically measured through the Science Motivation Questionnaire II (SMQII).1 Prior studies demonstrate that measures of student motivation to learn science are a fair measure of success in science, technology, engineering, and mathematics (STEM) courses.2,3 Positively influencing student motivation to learn science, thus, is a route to improving student learning outcomes in STEM courses. Psychologists have found that the temporal focus of a situation can drastically affect motivation (i.e. proximal vs distal goals),4 yet no investigations of temporal focus within science classrooms have been reported.

Utilizing Patch Metrics to Improve Classification of Remote Sensing Imagery Michael L. Treglia* and Megan E. Young Department of Biological Science, University of Tulsa, Tulsa, OK 74104-9700 Departments of Wildlife and Fisheries, Texas A&M University, College Station, TX 77843-2258 *e-mail: mike-treglia@utulsa.edu Problem: Classified remote sensing imagery is used to inform management of various natural resources, though achieving accurate results is a persistent challenge. In particular, some land cover types that are functionally very distinct can be spectrally similar, thus misclassification errors can yield poor decision-making. Relatively new, object-oriented classification methods that consider the shape of clusters of similar pixels can yield improved results, albeit often at considerable software expense and steep learning curves. Our Approach: We employ a two-stage classification procedure, that takes advantage of free and open source tools to improve upon per-pixel classification techniques. First we perform supervised classification to obtain a layer with patches of our focal land cover classes. We then calculate descriptive metrics for each patch, characterizing size and shape, and for each land cover class we extract the per-pixel probability of class assignment. Lastly, we perform a second supervised classification based on raster layers representing the aforementioned class probabilities and patch metrics. Case Study: A Complex Landscape of West Texas Study Area • We focused on a portion of the Mescalaro/Monahans Sand Dunes ecosystem in western Texas, USA, home to unique biodiversity and threatened by oil and gas development . • The landscape is complex and difficult to classify, particularly with regard to oil/gas roads and well-pads (made of caliche) and natural sand formations. • We strived to classify on Landsat 5 TM data, available for large portions of the globe for up to 27 years, at 30 m resolution. Results Deriving patch statistics from a per-pixel classification for use in a second classification run provided some benefit in our system (Fig. 3). Though there are still classification errors after stage 2, caliche roads and well-pads are better distinguished from sand formations. The stage 2 classification increased overall accuracy on our training dataset, from 94% to 98%. Though these results are positive, neither classification performed well on a smaller evaluation dataset (~50% overall accuracy), with the greatest confusion between living and dead vegetation. Discussion and Next Steps: Our two-stage approach for classifying remote sensing imagery effectively uses information about clusters of similar pixels to improve results. It is conceptually simple, and was done exclusively using freely available tools. The example presented here is a first attempt at this method, involving a complex landscape with fine-scale features, perhaps difficult to detect using Landsat imagery. Thus, we suspect this technique will yield greater benefit in landscapes with larger features, or using higher-resolution imagery. Fig. 1. NAIP 1 m aerial imagery (left) and false color composite from Landsat TM data (right) displaying NDVI, Green and Blue for our study area. Stage 2 Classification • Calculated metrics for each distinct land cover patch classified in stage 1, using Fragstats, and created raster layers for each metric. • Created raster layers of class probabilities from the stage 1 classification for each land cover class. • Performed supervised classification using Random Forests, on raster layers representing class probabilities and patch metrics. Methods Stage 1 Classification • Calculated NDVI and Tasseled Cap metrics for a single Landsat scene (Path 30/Row 38) from 2010 and stacked them with the original Landsat bands using QGIS and R. • Performed supervised classification using Random Forests (in R), based on 260 training areas derived from 1 m aerial imagery and our knowledge of the system.

KNOWLEDGE ABOUT CERVICAL CANCER AND AWARENESS OF PAP SMEAR SCREENING AMONG FEMALE NURSES IN HOSPITAL PAKAR SULTANAH FATIMAH Authors: Ruzila R, Azlina D, Siti Salmiah S, Noraini A, Rohayu M, Nazrah A. Institution :Nursing Unit, Hospital Pakar Sultanah Muar Johor P-151 NMRR ID:20-3008-56270 Introduction To have a successful cancer control program, nursing staff must be aware of facts about cervical cancer and screening tests themselves. This study was aims to assess the level knowledge about cervical cancer and awareness of Pap smear screening among female nurses in HPSF Methodology A descriptive cross-sectional study, a self- administered semi structured questionnaire, and selected by stratified random sampling method, involved the 239 registered nurses who worked in HPSF. IBM SPSS was used for data analyzed. Results Demographic background among nurse Table 1: Demographic characteristic (n=239) To determine the level of knowledge about cervical cancer and awareness of Pap smear screening. Figure 1: Level of knowledge about cervical cancer (n=239) Figure 2: Level of awareness of pap smear screening(n=239) To identify the association between experience working, knowledge about cervical cancer and awareness of Pap smear screening. Table 2: Association between years of experience working and level awareness (good level and poor level) among participants using simple logistic regression Variables Frequency (%) Mean Age 37.13* Experience working 12.79* Deparment Medical 62( 24.2%) Surgical and Orthopaedic 49(19.1%) Obsetric and Gynae 50( 19.5%) Paediatric 40(15.6%) Multidispline 27(10.5%) Anaesthesia 28(10.9%) Race Malay 252(98.4%) Chinese 1(4%) India 2(8%) Others 1(4%) Maritul status Married 250(97.65%) Widow 6(2.35%) Education Diploma 239(93%) Degree 18(7%) Attended CNE Yes 132(51.6%) No 124(48.4%) Parity 0 17(6.64%) 1 32(12.5%) 2 80(31.25%) 3 82(32.03%) 4 38(14.84%) 5 6(2.34%) 6 1(0.40%) Variable Crude OR (95%CI) P value Experience working 0.926 (0.871,0.985) 0.014 Discussion Cancer cervix is preventable, and one of important aspects is prevention in detection of the premalignant lesion by screening[1]. This study show that majority of the participants have a good knowledge about cervical cancer and most of the participants have a moderate awareness of the Pap smear screening. Moreover, if nurses themselves undergo screening tests regularly, they can be role models for other females in carrying out cervical cancer screening tests[2,3]. The association between years of services and level awareness were significantly (P=0.014). This also implise that more important in teaching curriculum and training programs should be incorporated about cancer cervix and screening[2]. Conclusion Knowledge about cancer cervix, screening and practice of Pap smear is good among female nurses in HPSF. Nurses, if properly aware of cervical cancer and screening methods, can educate the women in the community and increase health-seeking behaviour among eligible women.

CompressedSensinginWirelessCommunication Thomas Arildsen∗, Tobias Lindstrøm Jensen, Karsten Fyhn, Peng Li, Pawel Pankiewicz, Jacek Pierzchlewski, Hao Shen, Ruben Grigoryan, Søren Holdt Jensen, Torben Larsen Dept. of Electronic Systems, Aalborg University, Denmark ∗tha@es.aau.dk Abstract Compressed sensing has gained a lot of attention in recent years. While the famous Shannon-Nyquist boundary for sampling of analog signals provides a sufficient condition for the sampling frequency, it can be reduced substantially in situations where a signal is sparse in a given domain. This can lead to compressive sensing which can be formulated as an optimization problem where an under-determined system of linear equations is solved under the con- dition of a sparse solution. In our research group at Aalborg University we are using compressed sensing theory to address some important practical challenges in radio frequency communication and more generally in analog-to- digital conversion. Radio frequency receivers for modern telecommu- nication standards in power-constrained devices are increasingly challenged by the necessary sam- pling frequencies and hardware power consump- tion. Compressed sensing techniques may help ad- dress some of these challenges, for example by re- ducing the necessary sampling rate. This is a move towards the original, but hardware-wise unrealistic, ideas of software defined radios. In order to utilise compressed sensing, we must be able to represent the relevant signals sparsely – or, alternatively, find new signal structures that allow compressed sensing. In practice, various hardware imperfections as well as noise and interference limit the applicability of compressed sensing. These issues must be ad- dressed to make compressed sensing practicable. Multi-Coset Sampling Scheme ▶The multi-coset sampling scheme is one of sev- eral possible sub-Nyquist sampling schemes. ▶The multi-coset sampling scheme can be used to sample and reconstruct frequency sparse sig- nals. Reconstruction is possible with various al- gorithms that may have different performance. ▶We are focusing on the impact of hardware im- perfections on the reconstruction quality. Var- ious real-life restrictions such as practical sam- pling patterns are also important. ▶This research will bring multi-coset sampling schemes closer to real-life applications. ADC 1 x(t) x((m·L+c1)·T) = y1[m] ADC 2 ADC P x((m·L+c2)·T) = y2[m] x((m·L+cP)·T) = yP[m] Sparse Sampling Receivers ▶Applying multi-coset sampling on a conven- tional time-interleaved ADC may increase the input bandwidth. ▶Time-interleaved ADC traditionally uses uni- form sampling. We investigate introduction of randomized sampling. ▶We consider a sample-time error in each sub- ADC. Sample-time error is a random time delay for each sub-ADC, and it is a constant error for each sampling instance. ▶We identify these sample-time errors and ex- ploit them to introduce randomized sampling similar to multi-coset sampling.

The Governance of Digital Immortality & the Digital Afterlife Researcher: Khadiza Laskor khadiza.laskor@bristol.ac.uk https://www.bristol.ac.uk/cdt/cyber-security/ Supervisors: Professor Richard Owen Professor Andrew Charlesworth Digital Immortality & Digital Afterlife… …are terms that grew in prominence since the turn of the century. This prompted the emergence of ‘grief tech’ which includes the possibility to preserve and curate a virtual online persona from digital remains, enabling individuals to ‘live’ after their physical death. Governance & Regulation However, history is at risk of repeating itself: the ‘pacing problem’ (Collingridge, 1980) has often been observed when governing technology. This is the main theme being explored using ‘grief tech’ as a use case. Research Progress A systematic literature review on the framing of ‘Digital Immortality’ and ‘Digital Afterlife’, and the state of art of its governance, has revealed strong technological influences, with little emphasis on governance or regulation. This Year’s Focus Analysis of over 50 expert stakeholder interviews, with results from focus group discussions with the public (to be scheduled later) are expected to highlight how this innovation ought to be controlled, if at all. Further… …the combined results will be used to assess whether existing governance artefacts are able to protect an identifiable virtual online persona created by the individual before they died, or posthumously by a loved one. This multi-disciplinary PhD thesis utilises a flexible design process, based upon ‘Responsible Innovation’ (Owen et al, 2013). The approaches being adopted are empirico-inductive: thus, allowing for a comprehensive analysis in how such a nascent industry, loosely labelled as ‘grief tech’, could be governed. While the foci is on data left behind by the deceased, due to sensitivities associated with grief and bereavement, creative means are also being pursued. | poster |
Astyanax mexicanus: surface fish and Pachón Methods: • Cardiac cryoinjury • Histochemistry analysis • RNAsequencing • Real-time quantitative polymerase chain reaction (qPCR) • RNAscope • QTL analysis RESULTS (CONTINUED) MATERIALS AND METHODS SUMMARY FINANCIAL SUPPORT RESULTS BACKBROUND Distinct dynamics of the extracellular matrix during heart regeneration in different Astyanax mexicanus populations Zhilian Hu1, Madeleine E. Lemieux2, Mathilda T. M. Mommersteeg1 1. Department of Physiology, Anatomy and Genetics, University of Oxford, Oxford, UK 2. Bioinfo, Plantagenet, Ontario, Canada The cardiac regenerative capacity of Astyanax mexicanus populations is completely distinct in response to the injury. Surface fish can regenerate the ablated heart tissue, similar to zebrafish, while Pachón cannot and instead forms a permanent scar with excess extracellular matrix (ECM), similar to human. ECM is a dynamic three-dimension network of extracellular macromolecules including collagen and non-collagenous components. Its content, relative proportion, and spatial arrangement play a pivotal role during tissue regeneration. Any changes in ECM deposition can have a big impact on the ability to regenerate. Astyanax mexicanus allows us to identify the differences in ECM deposition and removal between a degradable scar in a regenerative setting and a permanent scar in a non-regenerative setting. Our research indicates ECM components and their regulating Matrix metalloproteinases (MMPs) are dynamically and differentially expressed during heart regeneration between surface fish and Pachón. Next, we will link the key scarring differences directly to both the genome and the ability for heart regeneration using new and prior Quantitative Trait Loci analyses. This will allow to find the most fundamental molecular mechanisms directing the wound healing process towards regeneration versus scarring.

NIMBLE: A language for algorithms for graphical models embedded in R Problem-specific hierarchical statistical models (graphical models) are used by domain experts in many scientific fields: • State-space or hidden Markov models for time-series data • Random field models for spatial data • Generalized linear mixed models for complex designed studies • Capture-recapture models • Non-parametric regression and distribution models • Combinations of these and many more ideas There are many unmet statistical challenges for hierarchical models: • Efficient Markov chain Monte Carlo (MCMC) for parameter estimation • Maximum likelihood (or empirical Bayes) estimation when the likelihood requires integration. • Approximation of normalizing constants (likelihood or marginal likelihood) for model comparisons. • Tools for model selection, an unresolved area of Bayesian methodology. • Tools for model averaging. • Tools for assessing/validating model fit or assumptions.

Generalized linear mixed models (GLMMS; lme4, MCMCglmm). • E.g. Generalized additive mixed models (mgcv). • E.g. Spatial models (spBayes, INLA). • E.g. Dirichlet process type models (dpPackage) • User cannot extend the model. 2. Provide a domain-specific language for writing general models and one or a few black-box algorithms. • E.g. MCMC is provided by BUGS (WinBUGS, OpenBUGS, JAGS), Stan, PyMC and others. • E.g. particle filtering is provided by BiiPS, LibBI, pomp, and others. • User cannot write new algorithms for the models. New computational statistics methods for general models Software for statistically savvy domain scientists Statisticians and computer scientists publish many new methods that are not accessible via software to domain scientists. • Model-specific methods can be distributed as R packages. • Model-generic methods are hard to code because the model must be abstracted.

All subjects were scanned with the same Siemens brand 3T scanner. The impact of pial surface errors related to overextension of gray matter boundary on automatically calculated brain volumes is very small. Unless the study requires highly precise volume measurements or focuses on the areas that were shown to have a significant number of errors, manual quality control may not be necessary. References Figure 1. Three regions of the brain with error clusters: lateral orbitofrontal cortex (A), paracentral lobule (B), and cerebellar tentorium (C). Table 1. Error frequency among inspected MRI images. A total of 233 errors related to overextension of gray matter boundary were recorded from the images. Here, we determine the number, location, and volume distorting effect of such errors in the brains of 51 first-episode psychosis (FEP) patients and 78 MRI images. 28 of the subjects had both baseline and 1-year follow-up images. The subjects had FEP in 2010–2016, and were recruited by the Finnish Institute for health and welfare (THL). The changes in local brain volumes as listed in aparc.stats between non-controlled and controlled images were on average very small (-0.09% +- 0.33). The average change in cortical thickness was -0.07% +- 0.14. 127 errors were in the left hemisphere, and 106 in the right hemisphere. The images went through manual quality control by a single researcher (V.V.), with error locations recorded. All MRI images underwent the full FS processing stream (recon-all) including automatic volume calculation. Mistakes in this automated process lead to the miscalculation of brain volume in the areas with incorrectly determined edges. 6 http://surfer.nmr.mgh.harvard.edu/ 7 Paul A.

The errors were not uniformly distributed in the brain: the most affected areas were the middle cerebral artery (59 errors) and the immediate vicinity of the cerebellar tentorium (50 errors). Watch a video about Figure 1: The effect is calculated by having a researcher manually examine the MRI images and manually correct the errors, and comparing the pre- and post intervention datasets and their volume measurements. Each set of error coordinates was converted to MNI 305 space as a single voxel.

Results Analysis of variance tests compared mean abundance data across multiple semesters. Results show that only three of the key species (Nassau grouper, Red lionfish, and Queen triggerfish) had a significant change. Abundance of Nassau grouper initially decreased from Fall 2004 to Spring 2005 and since has been increasing through Fall 2010. Significant increases were seen when comparing Fall 2010 to Fall 2005, Spring 2006, and Fall 2006 (P=0.06, P<0.01, and P=0.004; Figure 1). Results for Red lionfish showed a significant difference in all semesters when compared to Fall 2008 (P=0.001, P=0.001, P=0.041, and P=0.043; Figure 2). The mean abundance of Queen triggerfish is significantly different when comparing all semesters to spring 2007, when there was a significant rise in mean abundance ( P<0.05; Figure 3). Visual Surveys of Patch Reef Species Abundance in South Eleuthera, The Bahamas Phoebe Fitz, Marianne Foss-Skiftesvik, Meaghan Kachadoorian, Chris Lorient, Chris Pibl, Jackson Rafter Advisors: Matt Dawson and Skylar Miller Methods This study was performed off Powell Point in Cape Eleuthera, Bahamas during a seven-week period in Fall 2010. Twenty patch reefs, all within a proposed marine protected area, were surveyed twice during the seven-week observation period in order to maintain accurate results (Figure 5). Extensive fish identification training was conducted before research commenced to ensure proper field identification. Visual surveys were conducted in buddy pairs while snorkeling to record population abundance of the six key species (Figure 4). Mean abundance values of each species across all survey sites over the seven-week period were calculated. This data was then analyzed and compared to data from the past seven years. Discussion One reason for the increase in abundance of Nassau grouper may be the effectiveness of current fishing regulations. Fishing regulations are determined annually by the Bahamian government. For the year 2011, fishing is closed December 1 to February 28. Another regulation limits the size of the Nassau grouper caught to a minimum of three pounds (Department of Marine Resources 2010). The initial increase in Red lionfish population seen from 2007 to 2008 may be due to their invasive nature and therefore lack of natural predators. Because the Red lionfish originated in the Indo-pacific, locals had no previous knowledge of this species. However, now that handling techniques are more familiar, some local Bahamians are beginning to recognize Red lionfish as a good food source. Because Red lionfish spawn every four days and therefore have a very high reproduction rate, even the smallest catch by locals impacts their population. Despite this, the most probable reason for the decrease in Red lionfish population is that maximum carrying capacity was reached. As the Red lionfish population increased in South Eleuthera, competition for food and space may have caused the significant decrease. The population abundance of the Queen triggerfish has proved to be fairly constant over this ongoing study, with the exception of the atypical data collected in 2007. However, their population should continue to be monitored to ensure its stability, especially since the Queen triggerfish is economically important to the Bahamas. Their vibrant colors attract many tourists to snorkel on the patch reefs and they have been used in the past as a fishing alternative to Nassau grouper when their numbers were dwindling. The data supported the hypothesis for some of the key species, while was inconclusive for others. The increase in Nassau grouper populations is an example of how fishing regulations may have positive effects on species population abundance. However, this data is not conclusive enough to provide recommendations for future marine protected areas and/or fishing regulations in South Eleuthera, The Bahamas.

18th International Open Repositories Conference (OR2023), Stellenbosch University, South Africa, 12‐15 June 2023 Marcin Werla (mwerla@qnl.qa), Dr. Alwaleed Alkhaja (aalkhaja@qnl.qa), Dr. Arif Shaon (ashaon@qnl.qa) Qatar National Library In November 2022, Qatar National Library (QNL) launched a new repository service called Manara – the Arabic word for ‘lighthouse’ – with the ambition of capturing, curating, preserving and providing open access to all research outputs created in Qatar. This service builds on a national-level e-resources consortium that the Library has been coordinating since 2016, ensuring optimum licensing and financial terms for subscription-based access to research and educational content for 10 major institutions. Besides institutional-level cooperation, Manara welcomes all kinds of research-related open access contributions from all researchers based in Qatar on an individual voluntary basis. The Library is responsible for the basic content review before publishing. Introduction Manara is a new service and will initially operate as a pilot. The wider goal is to develop Manara as a core Library service that is strategically important for QNL's long-term mission and vision. The exact long-term sustainability model will be developed in cooperation with participating institutions after the initial pilot period, which runs until mid-2024. THE FUTURE Find out more at manara.qnl.qa Manara, as a comprehensive and sustainable research repository, contributes significantly to several UNESCO Sustainable Development Goals by enriching scientific, educational and cultural knowledge environments, supporting research communication and information sharing. The open access model promoted through the repository makes the contribution even stronger, opening Qatari research outputs to the world. UNESCO SDGs An important role of Manara is to help preserve institutional archives in the dynamic landscape of Qatar. To support the Library’s mission, Manara can preserve research and educational content from institutions that no longer exist, like the Qatar branch of University College London, UCL-Q, which was active between 2010 and 2020, and played the role of Center of Excellence for Cultural Heritage and Knowledge Management in the country, conducting around 100 research and education projects. LEGACY ARCHIVING The concept at the heart of a refreshed Qatar Foundation strategy revolves around creating a collaborative and diverse higher education ecosystem in Qatar that promotes interdisciplinary learning, research excellence, and global connectivity. The concept emphasizes the integration of multiple universities, research institutions, and educational facilities within a shared campus or network. It aims to contribute to the development of Qatar as a knowledge-based society and a hub for education and research in the region. This is a comprehensive development plan introduced by the government of Qatar to guide the country's growth and progress across various sectors by the year 2030. The vision emphatically focuses on four key pillars: human development, social development, economic development, and environmental development. The vision profoundly emphasizes the importance of creating a knowledgeable and skilled society, developing a knowledge-based economy, and promoting entrepreneurship and innovation. Qatar National Library actively promotes open access through a broad variety of services, to support global dissemination of, and unrestricted access to, Qatar-based research, including: • signing open access agreements with publishers and providing an article processing charges fund for Qatar-based researchers; • supporting international open access initiatives, like INTACT’s OpenAPC and Open Access 2020; • running events and training sessions; • providing information and advice to researchers about open access publishing and open licensing.

Crowdsourcing in History. New participatory and inclusive method- ological challenges for research in History in Spain (CrowdHistory) DH2023 COLLABORATION AS OPPORTUNITY ALLIANCE OF DIGITAL HUMANITIES ORGANIZATIONS, UNIVERSITY OF GRAZ AUSTRIA, 10-14 JULY 2023. Credits Scientific Publications The main objective of CrowdHistory project is to identify, analyse, test and standardise methodological practices of citizen participa- tion in Spanish R&D projects from the per- spective of Digital Humanities, both within and outside the academic field. by PhD. Lidia Bocanegra Barbecho - Digital Humanities responsible at Medialab UGR (Universidad de Granada- Spain) and tenure Track position at Contemporary History Department, UGR. lbocanegra@ugr.es | @Lidia_Bocanegra THE PROJECT AIM CROWDHISTORY METHODOLOGY To achieve the proposed objectives, CrowdHistory implements a four-phase methodology as follow: - Phase 1 - Detection of research projects in history that use public participation from citizen science. Design and structuring of a relational web database (DB), implemented through the Drupal Content Management System, version 9, PHP 7 and MariaDB 5.5. The established database (DB) allows classification parame- ters in closed lists and with free text fields, where explanatory information about the strategies of approaching the public has been added. - Phase 2 - Standardisation methodology on public participation in historical re- search. This phase will lead to first analyses and, as a result, to a first catalogu- ing of participatory processes (of citizen involvement) as well as engagement activities (public engagement). - Phase 3 - Testing and improving the methodology of public participation in his- torical research from citizen science through pilot cases. use of hybrid (physical/ digital) citizen laboratories where some of the classified participatory approach- es and techniques will be put into practice. - Phase 4 - Evaluation of the public participation and public engagement methodology and development of good practice guidelines. STATE OF THE ART The current state of research lacks scientific investigations that reflect methodologically and conceptually on public participa- tion in historical research in Spain. When we talk about public participation in research, we refer to Citizen Science (CS): this is scientific research coordinated by scientists in which ordinary people, amateur and non-professional researchers, participate in some aspect of the research (Eitzel 2017). This type of methodological research is practically new in the humanities; however, there are a discrete number of research projects that use CS that are currently underway or have already been car- ried out, which offer a suitable breeding ground with relevant data to carry out analyses in Citizen Science (Bocanegra et al. 2017). This citizen participatory aspect is one of the main characteris- tics of the Digital Humanities (DH) (Bocanegra 2020); in the last decade there has been a change in the way of doing research in the human sciences as society begins to have a participatory role during the research process; beyond being the subject of analysis to even participate in part or all stages of scientific production. This new way of doing science is strongly driven by the growing boom of web 2.0 and, within it, digital social net- works stand out as a place for interaction (Bocanegra 2020); betting on collective intelligence (Surowiecki 2004) and micro- PRELIMINARY RESULTS Currently, we have identified and classified 473 international projects that use CS through the project's web database: https://cohistoria.es/; of which 161 are Spanish initiatives or with Spanish participation. Data collection continues as new initiatives are found. An ad hoc classification has been made on the basis of two models: PPS – Public Participation Strategies and PES – Public Engagement Strategies, through which a series of participatory and public engagement activities have been i | poster |

Knudsen1 and E. Sidney Hunter2 U.S. Environmental Protection Agency, Office of Research and Development 1NCCT and 2NHEERL Mining ToxCast to define sensitive pathways Summary OBJECTIVE: build a framework for pre-prioritizing chemicals for developmental toxicity (DevTox) for potential application to chemicals regulated under TSCA (amended 2016). INPUTS: ToxCast data including new information on chemical effects in zebrafish embryos and in diverse mammalian embryonic stem cell lines (hESC, mESC). OUTPUT: generalized workflow to sort compounds by their predicted potential for DevTox and in silico modeling of quantitative cellular, tissue and phenotypic responses. Evaluating model performance • Assigning chemicals under amended TSCA to low and high priority comes with uncertainties in complexity of predicting toxicity during pregnancy. • A DevTox predictive framework will implement data from in vitro assays assessing embryonic cell growth and differentiation. • The framework will operationalize a defined interpretation protocol for computational synthesis and integration DevTox decision tree. • Multiscale modeling and simulation will provide tools and approaches to virtually reconstruct and analyze complexity and quantitative prediction. OBSERVATIONS: • ZFISH platforms were more sensitive but less specific than mESC or hESC platforms. • Model performance improves against more stringent in vivo criteria for DevTox. • Overall accuracy approaches 62% (ZFISH), 72% (mESC), and 84% (hESC). • The hESC model also predicts the critical concentration for human dosimetry.

De novo genome sequencing of Skeletonema marinoi and Surirella brebissonii Mats Töpel¹*, Magnus Alm Rosenblad¹, Ulrika Lind¹, Susanna Gross², Sandra Karlsten¹, Jens Persson¹, Mattias Backman¹, Anna Godhe², Anders Blomberg¹ 1. Department of Chemistry and Molecular Biology, University of Gothenburg 2. Department of Biology and Environmental Sciences, University of Gothenburg *mats@topel.se Introduction De novo whole genome sequencing of the two diatom species Suri- rella brebissonii (CCMP2919) and Skeletonema marinoi (GUMACC St54) are currently conducted as part of the Linnaeus Centre for Marine Evolutionary Biology (CeMEB) initiative at the University of Gothenburg. This work is part of the Infrastructure for Marine Genetic model Organisms (IMAGO) project, aimed at developing new marine model systems and provide genomic and genetic tools to study vital phenomena and components of coastal marine ecosystems. Protein translocation in diatoms A chloroplast’s genome only encodes ~100 proteins, but the organ- elle requires many more proteins in order to perform its functions in the cell. Translocons at the Outer and Inner Chloroplast enve- lope membranes (TOC and TIC, respectively) are the two multi- protein complexes in plants, red- and green algae that enable chlo- roplasts to import these essential nuclear-encoded proteins. Diatom plastids, on the other hand, are surrounded by four mem- branes where the outermost is continuous with the endoplasmic reticulum (ER) [8]. The second membrane (known as the periplas- tid membrane [PPM]) is the remnant of the secondary endosymbiont’s plasma membrane (proposed to be of red algal origin) [9]. The two innermost membranes are homologous to the outer and inner envelope membranes in plant plastids and are de- rived from the membranes surrounding the cyanobiont of primary plastids [10]. The identity of the TOC and TIC translocons in diatoms and most other chromalveolate organism groups (e.g brown algae, dinofla- gellates and apicomplexan parasites) is mainly unknown. How- ever, bioinformatics analyses of whole genome sequences from dia- toms has shown that these systems are also present in diatoms. Bullman et al. [11] reported the discovery of an Omp85 protein that is localized in the third outermost plastid membrane (homologous to the outer envelope membrane in plants) of the diatom Phaeodactylum tricornutum. To date, this Omp85 protein is the only reported putative member of the TOC complex in diatoms. Our phylogenetic analyses (including bacterial, plant and diatom sequences) reveals that the diatom sequences are of red algal origin and more specifically belongs to the Toc75 gene family. Unexpectedly long branches in the diatom part of the tree indicates a rapid, albeit even, evolu- tionary rate. This phenomenon has been reported on previously, but the significance of the phenomenon has not yet been thor- oughly investigated. Assembly statistics DNA libraries (insert size 150 and 3000 bp), of which one were gen- erated from an axenic culture, and one RNA library (300 bp) from Surirella brebissonii has been sequenced. One axenic 300 bp library from Skeletonema marinoi has been generated. Both genomes have been assembled using the CLC de novo assembler software package. Sequence reads where preprocessed using cutadapt [1] and the fastx toolkit [2] (for details see http://matstopel.se/notebook).

08-11 November 2021 Online Event Prediction of photoelectric effect log and facies classification in the Panoma gas field Felipe F. Melo CGG GeoSoftware (Formerly at PUC Rio) Contact: felipe146@hotmail.com 1) AIM Predict the photoelectric effect log on two wells and then perform facies classification. 2) Introduction Departing from seven wells in the training set, I impute missing values in the photoelectric effect log (PE) in one well and predict the PE log from two wells. Then, I aggregate these wells to the training data in order to perform facies classification. Distinct feature augmentation techniques are used in both log prediction and facies classification. I used the random forest algorithm for log prediction and the extreme gradient boosting for facies classification. Focusing on the generalization of the models, the hyperparameters were tuned with the nested and the leave two out cross validation, respectively. The well Churchman Bible is picked as test data, this well is chosen because it has all facies and a large number of samples related to facies of interest. 3) Dataset 4) Method 5) Prediction of photoelectric effect log 6) Facies Classification 7) Conclusions • The feature augmentation was successful in both prediction and classification. • The PE prediction score (72%) in the test well shows the good result of this approach. • The results for facies classification are acceptable because of the samples limitations, accuracy of 58%. • The accuracy of 86% on adjacent facies and 90% on BS, 57% on PS and 6% on D (critical facies) shows the effectiveness of the proposed approach. 9) References Dubois, M.

The well Churchman Bible is used as test dataset, i.e., the quality of the regressor and of the classifier will be evaluated on this well. All other nine wells are used as training dataset for facies classification. In the first part, the photoelectric effect (PE) log is imputed for the well Recruit F9 (12 missing samples) and computed for the wells Alexander D and Kimzey A using the Random Forest regressor. Before log prediction, I perform feature augmentation. In this case, it adds non-linearities computing quadratic expansion and by considering all second order interaction terms and applies a low pass filter with the 1D discrete wavelet transform in the logs. Therefore, the training set moves from six to twenty features before estimate the PE logs. The logs NM_N and RELPOS are not used in feature augmentation because it would make no geophysical sense. After prediction of the PE logs into the two missing wells, these wells are grouped with the seven wells used as trai | poster |

Social Life Cycle Application Conclusion and Recommendations Acknowledgements In this critical review, lithium mining is examined under the context of its extraction phase, examining how social and environmental outcomes in foreign mining projects may be echoed in new American mining endeavors. Industrial ecology tools, such as Social Life Cycle Assessments (SLCAs), can be utilized to draw comparisons of unit operations across varying countries and contexts. As part of the guidelines established by the United Nations Environmental Programme (UNEP) for implementing SLCAs, two Life Cycle Inventories (LCI) were conducted analyzing the social impacts of lithium mining operations. One LCI addressed lithium mines currently operating within South America (SA), while the other LCI investigated data on a Thacker Pass, a proposed mine within the United States (US). Social Life Cycle Assessment (SLCA) is a tool developed by the United Nations Environment Programme/Society for Environmental Toxicology and Chemistry (UNEP/SETAC) for the analysis of social impacts associated with a product’s life cycle from cradle to grave (UNEP, 2009). Although SLCA has evolved significantly in recent years, limited standardization of procedures has restricted its use in the US. Meanwhile, the U.S. is rapidly expanding its lithium mining industry to meet electric vehicle (EV) demand and stabilize lithium supply chains (Riofrancos, 2022). While US mining companies posit American mines as safer and more sustainable than those in the global South, storied negative social implicati | poster |

Management and Uncertainties of Severe Accidents L.E. Herranz (CIEMAT), S. Paci (UNIPI) MUSA was founded in HORIZON 2020 EURATOM NFRP-2018 call on “Safety assessments to improve Accident Management strategies for Generation II and III reactors” On June 15th, 2018 MUSA obtains the NUGENIA label that recognizes the excellence of the project Numerical tools are widely used to assess the Nuclear Power Plants (NPP) behaviour during postulated Severe Accidents (SA). Considering the complexity of the processes taking place during a SA and the inherent nature of numerical codes (numerics, spatial discretization, etc.), it is mandatory to quantify their embedded uncertainties taking into account the latest developments in methods and algorithms as well as the availability of computing resources. Mathematical tools for quantification of code uncertainties and sensitivities have been under development for many years, with a huge accumulated experience in performing Uncertainty Quantifications (UQ) with Best Estimate (BE) system codes, partly because of new requirements in regulations of some countries as part of the NPPs licensing processes. This is so far not the case for SA codes and only a few investigations have been focused on SA and UQ. MUSA has an “innovative research agenda” in order to move beyond the state-of-the-art regarding the predictive capability of SA analysis codes by combining them with the best available or improved UQ tools. By doing so, not only the prediction of timing for the failure of safety barriers and of radiological Source Term (ST) will be possible, but also the quantification of the uncertainty bands of selected analysis results, considering any relevant source of uncertainty, will be provided. Objective of the MUSA project Assess the capability of SA codes when modelling reactor/ SFP accident scenarios of GEN II, GEN III designs Identification of UQ methodologies to be employed, with emphasis on the effect of both existing and innovative SAM measures on the accident progression, particularly those related to the ST mitigation Determination of the state-of-the-art prediction capability of SA codes regarding the ST that potentially may be released to the external environment, and to the quantification of the associated code’s uncertainties applied to SA sequences in NPPs and SFPs MUSA Work Packages WP WP MUSA COordination (MUCO), coordinated by CIEMAT WP2 Identification & Quantification of Uncertainty Sources (IQUS), coordinated by GRS WP3 Review of Uncertainty Quantification Methods (RUQM), coordinated by KIT WP4 Application of Uncertainty Quantification Methods against Integral Experiments (AUQMIE) by ENEA WP5 Uncertainty Quantification in the Analysis and Management of Reactor Accidents (UQAMRA) by JRC WP6 Uncertainty Quantification and Innovative Management of SFP Accidents (IMSFP) by IRSN WP7 COmmunication & REsults DISsemination (COREDIS) coordinated by UNIPI Dissemination of Knowledge Special attention for knowledge transfer towards young researchers and Masters/PhD students Production of public learning modules to be published in the MUSA open website.

In many cases there are no data available for comparing bioactivity from HTS with relevant human exposures. The EPA’s ExpoCast program is developing high-throughput approaches to generate the needed exposure estimates using existing databases and new, high-throughput measurements. The exposure pathway (i.e., the route of chemical from manufacture to human intake) significantly impacts the level of exposure. The presence, concentration, and formulation of chemicals in consumer products and articles of commerce (e.g., clothing) can therefore provide critical information for estimating risk. We have found that there are only limited data available on the chemical constituents (e.g., flame retardants, plasticizers) within most articles of commerce. Furthermore, the presence of some chemicals in otherwise well characterized products may be due to product packaging. We are analyzing sample consumer products using 2D gas chromatograph (GC) x GC Time of Flight Mass Spectrometry (GCxGCTOF/MS), which is suited for forensic investigation of chemicals in complex matrices (including toys, cleaners, and food). In parallel, we are working to create a reference library of retention times and spectral information for the entire Tox21 chemical library. In an examination of five plastic children’s toys, as many as 114 and as few as 56 chemicals were identified in each toy, with between 0 and 40 unidentified chemicals in each. Putative endocrine disrupter, Bisphenol A (BPA), was identified as present in a product marked “BPA free”. Information on chemical constituents of products, while only a prerequisite to actual exposure, provides heuristics for estimating likely human exposure pathways for thousands of chemicals.

The antineutrinos were generated by six 2.9 GWth nuclear reactors and detected by eight antineutrino detectors deployed in two near (500 m and 600 m flux-weighted baselines) and one far (1600 m flux-weighted baseline) underground experimental halls. An improvement on the neutron detection efficiency determination was performed using a new neutron calibration campaign and dedicated data-simulation comparison. With a 1230-day data set, the IBD yield was measured to be (5.91±0.09)x10-43cm2/fission. The ratio between the measured to predicted reactor antineutrino yield is 0.952±0.014(exp.)±0.023(model). The comparison of the measured IBD positron energy spectrum with the predictions is also reported with a previous 621-day data set. A reactor antineutrino spectrum weighted by the IBD cross section is extracted for model-independent predictions.

I-RIM Conference 2019 October 18 - 20, Rome, Italy ISBN: 9788894580501 Adaptive admittance control for a safe and efficient human-robot interaction Federica Ferraguti, Chiara Talignani Landi, Lorenzo Sabattini, Marcello Bonf`e, Cesare Fantuzzi and Cristian Secchi Abstract— The possibility of adapting online the way a robot interacts with the environment is becoming more and more important. Nevertheless, stability problems arise when the environment (e.g. the human) the robot is interacting with gets too stiff. In this work, we present a strategy for handling the stability issues related to a change of stiffness of the human arm during the interaction with an admittance-controlled robot. I. INTRODUCTION One of the most revolutionary and challenging features of the new generation of robots is physical human-robot interaction (pHRI). In pHRI tasks, robots are designed to coexist and cooperate with humans in applications such as assisted industrial manipulation, collaborative assembly, domestic work, entertainment, rehabilitation or medical ap- plications. In these contexts, due to the desired coexistence of robotic systems and humans in the same workspace, main concerns are related to safety and dependability. A widely used approach consists in implementing interaction control strategies that guarantee a compliant behavior of the robot. In particular, admittance control is typically utilized for controlling industrial robots, that are generally characterized by a stiff and non-backdrivable mechanical structure [1]. For example, admittance control has been used to imple- ment robot manual guidance in [2] and [3], by means of the “walk-through programming” where the human operator becomes the teacher that physically guides the robot through- out the desired trajectory. When using admittance-controlled robots, instability can arise when interacting with stiff envi- ronments. Since humans are dynamic systems characterized by a time-varying impedance, they can behave in a stiff way and, consequently, give rise to instability when interacting with admittance-controlled robot. Instability induces, among other undesired effects, a deviation of the robot from the desired admittance behavior. Furthermore, it produces high amplitude oscillations of the end-effector, undermining the user safety during the interaction. The deviations have to be first promptly detected and then canceled (or reduced) to restore the stability of the system. The adaptation of the parameters of the admittance control is a common strategy for recovering the stability of the interaction as shown, e.g., in [4], [5] and [6]. In this work we show a novel strategy F. Ferraguti, C. Talignani Landi, L. Sabattini, C. Fantuzzi and C. Secchi are with the Department of Sciences and Methods for Engineering (DISMI), University of Modena and Reggio Emilia, Italy {name.surname}@unimore.it M. Bonf`e is with the Engineering Department, University of Ferrara, Italy marcello.bonfe@unife.it for detecting the rise of oscillations during the interaction between a human and an admittance-controlled robot and a parametric adaptation of the admittance for restoring a stable behavior. The proposed adaptation allows to keep the adaptive dynamics similar to the nominal one in order to avoid unbalancing effects and to increase the usability of the system. Preliminary results have been presented in [7] and [8], while in [9] a method for automatically setting the detection threshold using a thorough statistical analysis has been introduced. Moreover, a weighted energy allocation strategy has been proposed in order to consider separately translations and rotations. In this work we present the overall framework and we show the experimental validation of the control architecture. II. ADAPTIVE ADMITTANCE CONTROL The goal of the admittance control is to force the robot to behave in a desired way when interacting with the en- vironment. In this paper, we address the case of a robotic manipulator manuall | poster |

Figure 6 shows the ETGs and LTGs fraction as a function of redshift for different cluster masses. The evolution in redshift for the full mass range is dominated by low mass clusters - the size of our sample enables us to study dependence on both parameters simultaneously. Fraction of ETGs and LTGs 0 0.2 0.4 0.6 0.8 1 0.2 0.4 0.6 Galaxy type proportion mean cluster redshift all M200 0.2 0.4 0.6 mean cluster redshift 1013.5 < M200 < 1014 Msun 0.2 0.4 0.6 mean cluster redshift 1014 < M200 < 1014.5 Msun 0.2 0.4 0.6 mean cluster redshift M200 > 1014.5 Msun NEXT : BREAKING THE REDSHIFT-MASS DEGENERACY Figure 6 There is some disagreement in the literature concerning the evolution with redshift of the galaxy luminosity function (GLF) in galaxy clusters. It is unclear whether the red sequence (RS) is enriched by efficient quenching of blue late-type galaxies inside the cluster from z~1, or if this RS is built at higher redshift. To explore this issue, we apply our new version of the Adami and MAzure Cluster FInder (AMACFI) to the Canada France Hawaii Telescope Legacy Survey (CFHTLS) W1 field.

(Madrid, Spain), 3INAOE (Puebla, Mexico) MEGASTAR is a stellar spectral atlas for MEGARA (Multi Espectrógrafo en GTC de Alta Resolución para Astronomía). MEGARA is an optical (3650 – 9750 Å), fiber- fed, medium-high spectral resolution (R = 6000, 12000, 20000) instrument in operation on the GTC 10.4m telescope. The scientific exploitation of MEGARA demanded a stellar-spectra library to interpret galaxy data and to estimate the contribution of the stellar populations. MEGASTAR atlas is focused on the highest resolution setups, HR-R and HR-I, and already has almost 1000 stars (twice spectra) thanks to the filler-type OpenTime obtained up to now in 7 semesters. We have developed a web- based tool and a database that allow working in the project (for MEGASTAR team) and making the observations and products available to the scientific community. MEGASTAR WebApp Functionalities: § Visualization and search of the sources involved in the project (link to the SIMBAD database). § Visualization, search, download and plot the data product files (by using a java tool) of the observations. § Paint a graph of the stars grouped by three ranges of [Fe/H] as follows: all stars of the library, the observed stars of the library or the user stars uploaded by a file. § Download the releases of the reduced star spectra. § Download the statistics files: observations statistics by VPH and by stellar physical parameters.

Laser fluence (J/cm²) Electron temperature Free – carrier density Lattice temp. Melting Critical density Model includes: •Electron and Lattice temperatures (heating, coupling, diffusion, cooling). •Free-electron and hole density (1-2 photon ionization, electronic avalanche, convection, recombination) •Fresnel formulas of reflectivity and inverse Bremmstrahlung absorption •Drude model (EM behaviour) •Electron-phonon and electron-electron collisions are considered. EM plasmonic interference is modeled and the possibility of printing the pattern from electrons to lattice is checked. Result is : for high fluence, convection-diffusion is dominant on electron-lattice coupling, for low-fluence, it is possible to observe a priodic modification in lattice temperature profile. On these figures, F=500 mJ/cm². Calculated free-electron density, electron and lattice temperature are presented for a 500 mJ/cm² laser fluence, 800 nm NIR wavelength, and 100 fs pulse duration (FWHM). It has been reported that c-Si (100) melts from 0.2 J/cm² under ~100 fs laser irradiation. Our calculations based on a melting temperature criterium showed that, if melting occurs, resolidifcation front velocities are higher than maximum speed of recrystallisation, thus should be observed. However, calculations based on fusion enthalpy showed that no melting occurs. Our experimental measurements show that no melting/recrystallisation front is observable on Transverse Electron Microscopy pictures of the Si-protection layer interface. - Calculations showed that thermal processes (melting, evaporation, …) are not the mechanisms responsible for pattern transmission from electron to the lattice. Ablation may occur, but an ultrafast mechanism of ablation (~200 fs at 500 mJ/cm²) is required to support the interference hypothesis. - Calculations confirm the possibility of the surface electromagnetic wave (plasmon) to be responsible for ripple formation under fs laser irradiation, through the modification of absorption provided by a seed (defects, roughness, nanoparticle) under our conditions. - Calculations and experiments show that no melting occurs during ripple formation. - Experiments show that mechanism of ripple-to-beads transition occurs in a crysta | poster |

The characterization of the water vapor vertical distribution on Mars is currently a very active research topic. Until this last decade, the water cycle has been studied mainly with the analysis of column density abundances. The recent possibility of solar occultation (SO) observations has opened a new path towards a better understanding of the Martian climate [1]. The Mars we observe today is a dry and cold planet although there are abundant evidences suggesting a warmer and wetter environment in the past [2]. Despite being a minor species in the current Martian atmosphere (~0.03%), water vapor has a large variability throughout the year, resulting in a very complex hydrological cycle involving sublimation and condensation processes affected by dust and atmospheric transport [1].

We study its seasonal variability during 3 Martian Years (MY) analyzing almost 5 years (April 2018 to December 2022) of NOMAD SO observations. We present a detailed insight of specific periods showing the effects of dust storms and detections of supersaturation. NOMAD is an infrared spectrometer covering the spectral range between 0.2 to 4.3 µm. Its SO uses an echelle grating with with an AcoustoOptical Tunable Filter (AOTF) to select different diffraction orders to be used during the observations. The spectral resolution of the SO channel is λ/∆λ = 20,000. The sampling allows a vertical resolution of 1 km. Also, the AOTF permits probing the atmosphere at a given altitude through 6 different diffraction orders [7]. For this study, we use Level 1 SO calibrated transmittances [8] of diffraction orders 134 (30113035 cm1), 136 (30563081 cm1) for the lower atmosphere and 168 (37753806 cm1), 169 (37983828 cm1) for the upper atmosphere. We have developed preprocessing tools to identify and eliminate residual artifacts in the spectra (bending, spectral shift) using the linebyline radiative transfer algorithm KOPRA [9]. For the inversions, we use the latest calibration of the NOMAD AOTF and its instrumental line shape (ILS) [10]. The retrievals are done combining the spectra of low altitude orders (134,136) with spectra of high altitude orders (168,169) up to 120 km for occultations where those orders where observed simultaneously. The bottom panels show two examples of typical NOMAD spectra (black) after its bending and spectral shift corrections for diffraction orders 136 (panel A) and 169 (panel B) at 30 and 100 km respectively. We also show the fitting after the retrieval (red). For optimization purposes, we only fit the data at certain spectral windows where the strongest H2O absorption lines are located. The panel on the right shows a typical retrieved H2O vertical profile (blue) and the GCM a priori used during its inversion. For this example, we are not fitting the data | poster |

Overview Acknowledgements In cancers, alternative splicing and polyadenylation (APA) can affect transcript stability, transport and translation, and can change a transcript’s translated sequence. APA can be characterized with short-read sequencing using specialized library construction methods. For large-scale disease studies, however, it is desirable to characterize splicing and APA from a single library construction and sequencing run. In the work reported here, we describe SPAT, an analysis tool that uses de novo assembly of RNA-Seq data to Search for Poly(A) Tails. SPAT is designed to accept contigs from a range of de novo transcriptome assemblers. When used with Trans- ABySS, the overall pipeline reports fusions and rearrangements, indels, alternative splicing, and a range of types of APA.

RNA-Seq Assembly and Poly(A) Tail Detection RNA-PET Clusters Using data supplied by ENCODE for cell line A459, we first thresholded peaks in RNA-PET coverage tracks, then clustered peaks that occurred within 100bp of each other. We used the resulting clusters as ‘true’ events for validations and ROC-like curves. ROC-Like Curve true positive | An RNA-PET cluster with at least one CS call within 100bp. false positive | A CS call that is not within 100bp of an RNA-PET cluster. true negative | Cannot be defined. false negative | An RNA-PET cluster with no CS call within 100bp. 3. Comparing Cleavage Site Calls RNA-Seq Tools Trans-ABySS/SPAT | Assemble with Trans-ABySS and process with SPAT. Trinity/SPAT | Assemble with Trinity and process with SPAT. Cufflinks | Assemble with Cufflinks and call CSs at transcript ends. ROC-like curves, which were insensitive to thresholds for RNA-PET peak detection and clustering, show that SPAT works with other assemblers, and performs better than a method that uses annotations to determine ends of expressed 3’ UTRs. SPAT has a PPV of 90% when we require an RNA-PET coverage of 3 and 2 bridging reads supporting a CS call. Validation Counts Venn diagrams were generated with the true positives from each tool set. Increasing RNA-PET stringency reduces the number of true positives by 6% for Trans-ABySS/SPAT and 27% for Cufflinks.

Accuracy assessment of MERRA-2 temperature and humidity profiles over the tropical ocean using AEROSE observations and ECMWF analysis Bingkun Luo1, Peter J Minnett1, Goshka Szczodrak1, Nicholas R. Nalli2 •Reanalysis model output is extensively used in atmospheric research to complement the satellite and in situ data. NASA's Goddard Earth Sciences Modern-Era Retrospective analysis for Research and Applications v 2 (MERRA-2) assimilates measurements from different sources to minimize bias errors. The model data must be rigorously evaluated to assess their suitability to study a variety of questions. Here, Sea Surface Temperature (SST) and profiles of temperature and humidity through the marine atmosphere from MERRA-2 are compared to independent ship-based measurements of radiosondes, and retrievals from the ship-based Marine-Atmosphere Emitted Radiance Interferometer (M-AERI), and also the analyses fields of the European Center for Medium - Range Weather Forecasting (ECMWF). The ship measurements include those from Aerosol and Ocean Science Expedition (AEROSE) cruises of the NOAA Ship Ronald H. Brown in the tropical North Atlantic Ocean, focusing on the representation of the spatial and temporal variability. The results reveal that temperature and water vapor profiles from the MERRA-2 are in good agreement with the in situ measurements. For part of the cruises, the atmosphere included a mid-level dry layer emanating from North Africa, the Saharan Air Layer (SAL). With respect to difference, MERRA-2 humidity profiles shows a big difference (40%) with RAOBs at high altitude (pressure level < 300 hPa). These results support the use of MERRA-2 fields in a variety of research applications, including those directed at improving the accuracies of satellite-derived SSTskin retrievals. Abstract The MERRA-2 SST agrees well with M-AERI, and it has a mean bias of 0.125 K and have the potential to provide a satisfactory contribution to studies involving SST. The SST difference distribution between them shows there is negative bias near equatorial region, effort is still required to provide better data especially some water vapor-contaminated data. Table: Statistics of errors of MERRA-2 SST vs M-AERI 2. SST Validation MERRA-2 datasets: The NASA MERRA-2 reanalysis data were generated using the Goddard Earth Observing System data assimilation system by NASA's Global Modeling and Assimilation Office Data Assimilation System V5.12.4. Covering the earth observation data from 1980 to present. MERRA-2 analysis data are computed on a latitude– longitude-altitude cubed sphere grid at the same spatial resolution as the 3DVAR algorithm atmospheric model based on the Grid-point Statistical Interpolation. AEROSE: • A series of intensive field campaigns on the NOAA ship Ronald H. Brown in the Atlantic Ocean. • AEROSE data include complementary measurements to study the transport of aerosols from the African continent across the Atlantic Ocean, including: –Microphysical evolution and regional impacts –Regional atmospheric chemistry and marine meteorology AEROSE tracks, color indicates the days since departure. Independent Validation data: •Radiosonde (RAOB): Balloon-based instrument to make direct in situ measurements of air temperature, humidity, and pressure to about 30 km height. • ECMWF: Contains a set of atmospheric variables on a spatial horizontal grid of 0.5ox 0.5 o at 60 vertical levels. The ECMWF analysis is produced daily for 00, 06, 12 and 18 UTC. The four analyses per day are obtained by four- dimensional variational analysis (4DVAR) schemes. • M-AERI: An accurate, self- calibrating, Fourier transform IR spectroradiometer that measures emission spectra from the sea and atmosphere.

Figure 1) the locations and close- ups of the surveyed islands. Panel a-b) provide overview of study areas, sorted by letters as indicated in b). The islands Panambungan (g) and Barrang Lompo (i) were surveyed by Mann et al., 2016. The red S. indicates a third island from Mann et al., 2016 where only living microatolls are found. This island is not shown here (see figure 3 for LMA elevations). Figure 2) All related RSL curves derived from fossil microatolls and their modern counterparts. Panel a) the positions of the islands are indicated by letters and colors and correlate to RSL graphs. All islands show comparable RSL results except the data set from Barrang Lompo, which shows a noticeable low RSL curve. The two studies from De Klerk, 1982 and Tjia et al.1972 show RSL results up to 6 meter above the present sea level, whereas the new data and the data by Mann et al., 2016 show RSL results of less than one meter above today. One possible explanation is that the earlier RSL results reflect extreme storm or tsunami events. Additionally, the GIA predictions mismatch the data and therefore,we propose to explore different ice models e.g. ICE-6G by Peltier et al., 2015 or ANICE ( De Boer et al., 2014). Figure 4) RSL indicator points for the Spermonde Archipelago and the ICE-5G GIA model (Peltier, 2004) and five different mantle viscosities for the same area. The gray band indicates the lowest and highest GIA prediction for this region. Shown are two marine limiting points from Tjia et al.,1972, 16 marine and two terrestrial limiting and one index point by De Klerk,1982, 21 sea-level index points from Mann et al.,2016 and the 24 newly surveyed data points.

The highest HLC was measured on Sanrobengi. This island is placed only one km from the coast of Southwest Sulawesi. The HLC from Sanane, Panambungan and Barrang Lompo differ slighty from each other but they are within a comparable range. These islands are located in the middle of the Archipelaho. On Tambakulu the HLC signal is the lowest. It is placed at the outer part of Spermonde ~70 km from the coast of the mainland. This trend might be based on differences in the local mean sea level or partial tides from the coast to open ocean due to a deepening bathymetry.

The Heliocentric Model of Open Science Documentation Understanding Scientific Information Stewardship Top-Down and Bottom-Up v6 29NOV2024 Monica Gonzalez-Marquez, et al*, Open Science Advocate mg246@cornell.edu DOI: 10.5281/zenodo.14242541 1. Do away with a paper-centric model of documentation 2. Return to first principles and allow Scientific Questions and their constraints to guide documentation structure. 3. For optimal communication, allow the labor of the scientific process to determine: a. What needs to be documented b. How it should be documented Golden Rule: Documentation is for communication with humans The documentation tools we build are meant to serve the components of the scientific process, not exist independently: Data without its context is meaningless. Credit: T Šimko. METHODS METHODS *paper with collaborators forthcoming Scientific documentation should not be constrained by the limits of the out-of-date research article. Scientific information takes make shapes and model media should be used to accommodate it. The purpose of documentation is to Communicate our science to current and Future generations. Science is a verb, it is labor. RDM should be grounded in preserving Information about the labor that produced the data, as well as the data itself. Instead of allowing the paper and publishing constraints to dictate what information is documented for posterity and how, Helio positions the research question at the helm of record-keeping. It is in turn, constrained by the resources needed to ask the question. These two layers are constrained by the communicative drive: science that is not communicated in usable fashion, may as well not exist. It is also a complete waste of resources, and thus not sustainable. The methods satellite below shows some of the labor involved in completing the methods component of a human science study. These details are indispensable to understanding how to interpret and potentially reproduce a study. They are also indispensable to accurate peer review. Current documentation practices either grossly under-describe or completely omit these needed details. Helio provides needed structure to Open Science efforts by helping map tools, infrastructure and other resources directly to components of the scientific process, thus reframing them as being directly at the service of documenting complete research processes for posterity. Helio uses labor as the basic unit to breakdown scientific processes for documentation. These satellites are not mapped to sections in a paper but to components of scientific processes, as instantiations of the scientific method, and as the labor needed to complete them. This presupposes that scientific processes and their components will vary according to discipline. This model is an analogy of the original planetary model transition process. Just as it was an error to position the Earth at the center, it has been an error to place the paper at the helm of scientific documentation. It doesn’t matter how sophisticated a machine learning algorithm might be or what A.I. can do, the ultimate interpreters of scientific information will always be people. Hence, we must document so that information is usable and understandable by people. ©Inês Silva for all figures unless otherwise noted The paper is demoted to become the narrative. In this way it assumes the role it has in practice which is to function as an extended abstract with links to detailed, usable descriptions of the labor and labor products of the scientific process. | poster |
Centro Universitário Euroamericano - UNIEURO / Curso de Medicina Humanidades Médicas REDUÇÃO DE DANOS: USO DE PSICOESTIMULANTES POR ESTUDANTES DE MEDICINA 1Autores: MARIANA DIAS TEIXEIRA; NATÁLIA FERNANDES CAVALCANTI; NICOLE COSTA DE HOLANDA; VALENTINA DINIZ CATHOUD; PEDRO AUGUSTO M FERREIRA ; WESLEY RIBEIRO DE CASTRO 2 Orientadoras: VANESSA TEREZINHA ALVES TENTES; PROFª MS DIANA ARISTOTELIS ROCHA DE SÁ INTRODUÇÃO O uso de psicoestimulantes, como o metilfenidato, tem se tornado comum entre estudantes de medicina, que recorrem a esses medicamentos para melhorar o desempenho acadêmico, principalmente em situações de alta pressão. No entanto, o uso indiscriminado sem prescrição médica levanta preocupações sérias sobre os efeitos colaterais e o risco de dependência. Diante disso, a abordagem de redução de danos emerge como uma estratégia fundamental para minimizar os impactos negativos dessa prática, promovendo um uso mais seguro e informado dos medicamentos. OBJETIVO Este artigo busca discutir a aplicação de estratégias de redução de danos relacionadas ao uso de metilfenidato por estudantes de medicina, com foco em minimizar os riscos à saúde física e mental, além de fornecer suporte educacional e psicológico para esses indivíduos. MÉTODO RESULTADOS A revisão revelou que aproximadamente 23,3% dos estudantes de medicina recorrem a substâncias psicoestimulantes, como o Venvanse e o Ritalina, para superar a fadiga e melhorar o desempenho acadêmico. Notavelmente, 57,1% desses indivíduos utilizam tais medicamentos sem prescrição médica ou diagnóstico formal, obtendo-os de forma ilícita através de amigos, parentes ou receitas falsas. O uso de metilfenidato sem prescrição entre estudantes de medicina é uma questão crítica que exige intervenção imediata. As estratégias de redução de danos, quando aplicadas de forma eficaz, podem diminuir os riscos à saúde e promover o bem-estar geral dos estudantes. É essencial que as instituições de ensino médico implementem programas educacionais e de suporte que abordem as causas subjacentes ao uso desses medicamentos, proporcionando um ambiente acadêmico mais saudável e seguro.

Revista Corpus Hippocraticum, 2(1) CONSIDERAÇÕES FINAIS Foi realizada uma revisão de literatura em bases de dados como PubMed, Scielo e LILACS, com foco em estudos sobre o uso de metilfenidato entre estudantes de medicina sem diagnóstico de TDAH (Transtorno de Déficit de Atenção e Hiperatividade). Foram analisadas pesquisas publicadas nos últimos cinco anos, que abordam tanto os efeitos do uso quanto as estratégias de mitigação dos danos associados ao uso não supervisionado de psicoestimulantes A rotina dos estudantes de medicina é marcada por alta carga de trabalho, longas horas de estudo, estágios e preparação para exames. Com isso, muitos estudantes recorrem a estimulantes como o Venvanse e a Ritalina, com a expectativa de melhorar a capacidade de concentração, aumentar a produtividade e diminuir a fadiga mental e física.Esses psicoestimulantes agem inibindo a receptação dos neurotransmissores, resultando em um aumento da concentração extracelular de dopamina e norepinefrina. Contribuindo para a melhora dos sintomas associados ao TDAH, como a desatenção, hiperatividade e impulsividadeApesar dos benefícios percebidos, a eficácia real desses medicamentos para indivíduos saudáveis, sem diagnóstico clínico, é questionada, com evidências sugerindo que o efeito placebo pode desempenhar um papel significativo na percepção de mel | poster |

ABSTRACT Hepatitis E virus (HEV) is a lesser-known hepatitis virus, but its worldwide spread is doubtless and has increased recent years. Zoonotic spread of HEV, mainly due to genotype (gt) 3, has emerged in developed countries in the past decade. The current study has shown for the first time that domestic pigs in Bulgaria are widely infected with HEV. There is a need for a method for the cost-effective detection of the HEV infection and production of HEV immunogenic proteins that can be used as diagnostic antigens for the serological tests. Also, in this study we have compared the results from a commercial ELISA and an in-house ELISA test based on HEV open reading frame (ORF) 2 protein produced in planta, the sensitivity and the specify of the tests were evaluated. The development of a HEV diagnostic kit based on plant-derived ORF2 capsid protein is our goal and this will help to reduce the cost of such a kit and to enable diagnoses of HEV in developing countries. Serological diagnostics of hepatitis E virus infection in pigs based on capsid protein (ORF2 genotype 3) expressed in planta – sensitivity and specificity Katerina Takova 1, Tsvetoslav Koynarski 2, Valentina Toneva 1, 3, Gergana Zahmanova 1, 4 Acknowledgements In total, 433 swine blood samples were collected from 19 different pig farms and 1 slaughterhouse, located in eleven districts across Bulgaria—Pazardzhik, Plovdiv, Stara Zagora, Yambol, Ruse, Razgrad, Silistra, Shumen, Varna, Dobrich, and Burgas district. The samples were collected during 2017 (n = 75), 2018 (n = 158), and 2019 (n = 200). In 2018 samples were taken from two age-groups, 6- month-old pigs that weighed around 80–100 kg (n = 78), and approximately 3- month-old pigs that weighed around 30 kg (n = 80). The samples taken in 2017 and 2019 are all from 6-month-old pigs. In addition, 32 meat chunks from wild boar were collected for meat juice extraction. The samples were collected from animals hunted in Stara Zagora, Vratsa, Montana, and Dobrich districts during the official hunting season. CONCLUSION: This study confirmed that plant-derived HEV diagnostic antigen could provide a cost-effective and scalable alternative of the commercially available coating protein. This research was funded by the Research Fund at the University of Plovdiv, competition “Young Scientists and Doctoral Students” MU21-BF-02, the Bulgarian National Fund, Project DNTC/Russia 02-6, Project PlantaSYST. PlantaSYST has received funding from the European Union’s Horizon 2020 research and innovation programme (SGA-CSA No 664621 and No 739582 under FPA No. 664620) Figure 1.

Potential Cost-saving for Liquid-to-Solid Medicines among Paediatric Patients Wei Chern Ang1,2, Mohamad Syafuan Fadzil2*, Chian Khie Lim2, Nur Inani Mohamad Nasir2, Muhammad Asyraf Amir2 1 Clinical Research Centre, Hospital Tuanku Fauziah, Ministry of Health Malaysia 2 Department of Pharmacy, Hospital Tuanku Fauziah, Ministry of Health Malaysia BR-08 NMRR-18-2790-44206 Introduction The World Health Organisation (WHO) recommends that children be treated with oral solid medicines for drugs, especially those require a precise dose titration.1 Problem statement: Factors that can affect a child’s success in swallowing pills include developmental stage, fear, anxiety, intolerance of unpleasant flavors and failure to appreciate the risks associated with the non- compliance. Inadequate dosing flexibility without the need of tablet crushing explained the lack of usage of solid oral formulation in pediatrics.2 The current practices only based on preference of prescribers and patient’s parent/care. Justification of Study: •There are still lack of evidence regarding the solid oral formulation suitability in Malaysia • There is no published study in Malaysia that analyses the cost differences when oral liquid medications were changed to oral solid medications in a hospital outpatient setting. Objective: 1. To examine the association of demographic and solid dosage suitability. 2. To investigate factors affecting prescribing of solid oral dosage dorms. 3. To examine the potential cost savings if patient were prescribed with solid over liquid preparations. Methods This cross-sectional study conducted from October 2018 to March 2019 among patients visiting Paediatric Clinic, Hospital Tuanku Fauziah (HTF), Kangar, Malaysia. Discussions/Conclusions 1.

Models were tested for compatibility with Sim4Life software. For some models reconstruction of missing parts as such wings and legs were necessary. Those were done using references from literature. For manual tasks, python scripts using Blender API workflows were created where was possible to automate the work. Scripts can generate simple structures like antennas and legs segments.

As telecommunications evolve (from 4G to 5G), the exposure of insects to RF-EMFs is likely to vary [1]. - Near powerful antennas, pollinators like bees face relatively high levels of RF-EMF exposure. This exposure can cause biological reactions in insects [2], yet the consequences of RF-EMF exposure on insects remain uncertain [2]. ETAIN has received funding from the European Union’s Horizon Europe research and innovation program under grant agreement No. 101057216 To assess the absorption of RF-EMFs in insects by utilizing detailed anatomical 3D models derived from CT scans, and to develop adaptable models compatible with EMF simulation software for various simulation scenarios. In this poster we focus on the process of extracting CT scan data to 3D models. Conduct simulations across each model at frequencies (1.8, 3.5, and 26 GHz) to verify whole-body averaged absorbed power, specific absorption rates and absorbed power densities. This will facilitate the analysis of how the distinct shapes of insects influence the results of these simulations. Implement simulations on heterogeneous models by assigning varied dielectric properties to different parts of the insects. This approach will enable a more detailed and accurate representation of real-world conditions. Additionally, undertake simulations that focus on the internal structures of insects, thereby providing deeper insights into the internal effects of RF-EMF exposure. By executing these steps, the project aims to shed light on the complex interactions between electromagnetic fields and biological entities, offering valuable data for both scientific understanding and practical applications in the field of bioelectromagnetics.

Scientific Knowledge Graphs and Metadata Infrastructure Daan Broeder, Menzo Windhouwer, Michael Kurzmeier, Katja Moilanen CLARIN ERIC, KNAW/HuC-DI, OAEW, TAU-FSD Scientific Knowledge Graphs Scientific Knowledge Graphs (SKGs) have recently gained popularity as a rich metadata structure for describing research activities using triples. The idea that a fully connected graph better represents the real world than a hierarchical structure is now widely accepted. Current implementations are the OpenAIRE Research Graph, PID Graph (DataCite), Open Research Knowledge Graph (TIB), … OpenAIRE Graph data model Data Cite PID Graph content From Scholarly to Scientific Knowledge Graphs? Within the RDA WG SKG Interoperability Framework, some existing SKGs have been developing a standardised model for SKGs. However mainly from a perspective of publishing and measuring research output for funders. To better model the research process, entities and relationships involving data creation and processing, such as processing services and instruments, are needed The research communities collaborating in the OSTrails project are advancing this work in the SKG-IF WG. Metadata Interoperability: SKGs to the rescue? In the OSTrails project the creation of SKGs by communities is an important means for improving the Discoverability and Interoperability of the community resources. From the SSHOC science cluster a number of CLARIN, DARIAH and CESSDA partners closely collaborate.

We monitored EK Draconis for about 30 nights with the TESS’s op*cal photometry and ground-based spectroscopy, and finally detected a superflare in white-light and Hα. APer the superflare with radiated energy of 2.0x1033 erg, a blue-shiPed Hα absorp*on component with a large velocity of -510 km s-1 appeared. The temporal changes in the spectra greatly resemble the Sun-as-a-star spectra of solar filament erup*ons, indica*ng a common picture of solar and stellar filament erup*ons. The comparison of this stellar filament erup*on with solar filament erup*ons in terms of the length scale and velocity strongly suggests that this would eventually become a stellar CME. The mass of erupted filament of 1.1x1018 g is surprisingly 10 *mes larger than those of the largest solar CMEs. The huge filament erup*on and an associated CME on the young Sun-like star provide the first opportunity to evaluate how the young Sun-like star/young Sun affects the environment of young exoplanets/young Earth as well as stellar mass/angular-momentum evoluCon (cf. the faint young Sun paradox). 1.

Contact us now info@csem.ch • www.csem.ch Developing high-performance and safe electrolyte for silicon and lithium metal batteries Sufu Liu, Leonardo Pires Da Veiga, Chengyin Fu, Mohammed Srout, Andrea Ingenito CSEM Sustainable Energy Center, CSEM SA, Switzerland In-situ thermally triggered polymer for silicon battery electrolyte Abstract: Compared with the state-of-the-art graphite anodes, silicon and lithium metal are considered as the most promising alternatives for higher energy density lithium batteries owning to their high theoretical capacity. However, significant challenges such as low coulombic efficiency, short cycle life and safety concern have seriously hindered their practical applications. [1,2] To enable the use of silicon anode, we are developing a polymer electrolyte with self-healing properties to stabilize the electrode interphase and restrain the huge volume change of silicon material. When compared with commercial carbonate liquid electrolyte with or without additives, our designed polymer electrolyte enables the NMC622//Si full cell with improved capacity retention and combustion resistance. Meanwhile, for rechargeable lithium metal batteries, our designed nonflammable electrolyte also enables the LFP//ultra-thin lithium metal (25 µm) with greatly extended cycling life, which delivers more than 88% capacity retention after 400 cycles. Our research paves the way for safer and more efficient lithium-ion batteries with silicon or lithium metal-based anodes, which will help to realize higher energy density and longer-lasting battery technologies. Conclusion and future work • In-situ thermally triggered polymerization is a promising method for fabricating polymer electrolyte with self-healing properties outperforming the commercial carbonate electrolyte. • Electrolyte engineering with aggregate and contact ion pair structures is an effective strategy to develop advanced electrolyte with high Li metal Coulombic efficiency. • Thermally evaporated thin Li metal and advanced electrolyte design could be an effective combination to promote long-term cycling of lithium metal batteries.

ENRICHING THE EVIDENCE BASE OF CO-CREATION IN PUBLIC HEALTH WITH METHODOLOGICAL PRINCIPLES OF CRITICAL REALISM INTRODUCTION Meta-theory, such as Critical Realism (CR) provides a foundation for understanding and researching phenomena. CR, originating from Bhaskar's work, distinguishes between the real and observable world and encourages exploring complex social phenomena with a focus on causal mechanisms. Co-creation research lacks explicit meta-theoretical foundations, whereas CR is a convincing proponent for hypothesised mechanisms to have the strongest explanatory power, related to empirical evidence. This study aims to explore critical realism as a promising meta-theory providing clear methodological principles [1,2] to enrich the evidence base for co-creation in public health research.

The breakdown of current gyrochronology as evidenced by old coeval stars Diego Godoy-Rivera(★), Joaquín Silva-Beyer, Julio Chanamé • Gyrochronology promises to deliver stellar ages for field main-sequence stars from rotation period measurements. • Before being widely used, the age- rotation relations must be comprehensively examined. • We develop a new method to test the state-of-the-art gyrochronology relations with old coeval stars. • In Figure 3, the members of Clusters show a better agreement with gyrochronology (highest peak), followed by the Wide Binaries. • We use Random Pairs as a control sample to calibrate the expected agreement for unassociated stars (assembled by disassociating the binary components). • The Random Pairs show a distribution in agreement with theoretical expectations (Expected ΔProt) • Our results demonstrate that the gyrochronology relations under study (Angus+19, Spada & Lanzafame 2020) do have predicting power, as the sets of coeval stars (Clusters, Wide Binaries) are in better concordance than the unassociated Random Pairs. • In Figure 4, we test the fractional agreement with gyrochronology as a function of age by using the different samples. • We find a good agreement for young ages (≲ 1 Gyr) , but a clear degradation towards older ages (≳ 2 Gyr). • This highlights the need for novel empirical constraints at older ages, which may allow revised gyrochronology calibrations.

IMPORTANCE OF OCEAN HEAT CONTENT TO THE GLOBAL CLIMATE SYSTEM Eileen Maturi1, David Donahue2, Deirdre Bryne1 1. NOAA/NESDIS/STAR 2. NOAA/NESDIS/OSPO Ocean Heat Content (OHC) The Ocean Heat Content is a measure of the integrated vertical temperature from the 26o C isotherm to the sea surface where surface boundary conditions exist (area under the curve in Fig. 1). The 26o C isotherm defines the lower limit at which convection can develop and strengthen. Surface winds generate turbulent mixing within the uppermost part of the ocean; this layer is called the Mixed Layer, and can often reach depths of hundreds of meters. Turbulence associated with the Mixed Layer is responsible for providing a large reservoir of heat energy that can be tapped into by a tropical cyclone. This can intensify and extend the lifetime of the cyclone. Figure 1. Schematic of OHC calculation. The red shading shows the true OHC by integrating the black temperature profile. The dashed blue line shows the approximated temperature profile of the upper ocean. Summary The Madden Julian Oscillation (MJO) and the El Nino/La Nina oscillations have global impacts which affect all the basins. It is important to know the Ocean Heat Content of all the Ocean Basins to predict the rainfall patterns, tropical and mid-latitude cyclones and drought. All these phenomena are components of the Global Climate System. NOAA/NESDIS generates a daily suite of satellite-generated OHC products for the Atlantic and Pacific. There are plans to generate a suite of OHC products for the Indian Ocean. Operational Ocean Heat Content (OHC) Products IMPACTS • The OHC products are important to the monitoring and understanding of Coral Reef systems. Coral reefs are sensitive to unusually warm water. Increased Ocean Heat leads to the destruction of Coral Reefs. • Higher oceanic heat content leads to increased rainfall, which is beneficial for agriculture. • Increased oceanic heat content in the Northern Indian Ocean leads to increased summer monsoon rainfall in India. • Improved ecological forecasting leads to better management of fish stocks, which are an important food source for ocean-bordering countries. There is only one true ocean, the “World Ocean.” For simplicity, the World Ocean is divided into 5 interconnected ocean basins. They are the Atlantic, Pacific, Indian, Arctic, and Southern Oceans. Climatic Variability The Indian Ocean is the warmest of the 5 ocean basins. An Indian OHC product can provide information about the Madden Julian Oscillation (MJO), which is a major factor in determining rainfall, drought, and tropical cyclone patterns in the Eastern Hemisphere. MJO can be visualized as alternating regions of rising air and sinking air. The rising air is associated with tropical rainfall. The sinking air is associated with drier conditions, allowing more solar insolation to reach the ground, inducing drought. It can also play a role in strengthening or weakening tropical cyclones. In addition, the OHC can be used to gauge the strength and duration of the Indian, Asian and North American Summer Monsoons. The MJO typically moves across the tropical Indian Ocean and western Pacific before weakening; though it occasionally circumnavigates the global tropics in 30- 60 days (1-2 months). MJO differs from El Nino/La Nina primarily in that the MJO recurs more frequently (lasting 1-2 months),compared to El Nino/La Nina which recurs less frequently (lasting 6-9 months or longer). The OHC is especially important for the Atlantic and Pacific Basins to help gauge the intensity and duration of El Nino/La Nina, tropical and extratropical (mid- latitude) cyclones, and anomalous rainfall patterns. | poster |

Extraction of historical information using semantic techniques and knowledge graphs Jorge Álvarez Fidalgo Introduction In the framework of the Semantic Web, knowledge graphs such as Wikidata have emerged as powerful tools to represent and or- ganise large amounts of information in a structured way (linked data). Our aim is to create a methodology that enhances the extraction of information from digitised historical documents by relying on external knowledge graphs, feeding them back in the process. Research questions •RQ1. How can we extract linked data from historical documents? •RQ2. Is it possible to use data from external knowledge graphs to improve the extraction process? •RQ3. Is it possible to detect errors and shortcomings in external graphs from the extracted information? •RQ4. How can we use NLP techniques to improve the accuracy of the linked data obtained? Methodology •To solve RQ1, we extract triples (?head, ?rel, ?tail). •In order to get all ?head -and some ?tail- entities we perform NER using existing M-BERT [1] derived models. •To extract ?rels we propose to perform link prediction on Wikidata in two phases -thus addressing RQ2-. Link Prediction (I). Semi-inductive prediction [2] using tail prediction models trained on Wikidata datasets, such as KGT5 [3]. To restrict the number of properties to be predicted, we use Shape Expressions [4]. Link Prediction (II). Fully inductive prediction [2] in which, based on the information extracted in (I), we define property paths in Wikidata -by means of SPARQL queries- that, if they exist between two entities, indicate a possible relationship between them. Preliminary results To evaluate this approach we are applying these techniques on a corpus of Spanish medieval notarial records consisting of 128 documents [5]. We focus on three types of relationships of varying difficulty for their detection: father-child, spouse and sibling, obtaining high recall [0.60-0.87] yet very low accuracy ([0.06-0.08]). Preliminary conclusions •Most of the relevant triples are extracted successfully. •Those undetected are mostly due to a) incomplete information in the knowledge graph (RQ3) and b) relationships that do not adhere to any pattern. •Accuracy is very low since many non-relevant pairs of entities match the patterns. •RQ4 may be of help in this regard, thus facilitating the work of the human-in-the-loop.

II. Materials • Samples selected from naturally deformed, mafic blueschists with variable mineralogies spanning a broad range of the blueschist facies P-T conditions. o Bandon OR: BAN09, BAN15, LAB34 o Cycladic Islands: CY106, CY107 o Diablo Range CA: DR221, DR265 o New Caledonia: LAB555, LAB570, LAB572 o Catalina Schist CA: GB15-02A • Kinematically oriented thin sections prepared (foliation normal/lineation parallel) for EBSD analysis. Blueschist sample P-T estimates from the literature overlain on metamorphic facies diagram with slab-top paths of van Keken et al. (2018). VI. Future Work • The remaining mafic blueschist samples targeted for this study will be mapped, analyzed, and integrated into the framework of this compilation study. • Synthetic receiver functions will be applied to subduction zone models using the results from this study to develop constraints applicable to imaging of blueschist-metamorphosed oceanic crust. • Deformation experiments on glaucophane samples at varying temperatures, strain rates, and initial grain sizes in combination with microstructural analysis of recovered samples will be used to link observations of naturally deformed blueschists to an experimentally determined flow law. III. Methods • We can better understand subduction zone dynamics by using exhumed subduction exposures to constrain remote geophysical observations. • Seismic anisotropy can illuminate subduction zone structure and link deep processes to their expression as geological hazards at the surface. • Understanding the range of seismic anisotropy in mafic blueschists, a key constituent of subducting slabs, will improve imaging of the subduction zone interface. The seismic anisotropy of the blueschist samples (in AVp %) as a function of fabric strength of the [100], [010], and [001] pfJ-indices of glaucophane in the samples—corresponding to the a-, b-, and c-axes respectively—displays a general increase in magnitude of anisotropy with glaucophane fabric strength. The strongest correlation between pfJ-index and AVp % occurs with the [100] direction. Misorientation to mean orientation maps of glaucophane in samples CY107 (top) and GB15-02A (bottom), representative of samples near the deepest and shallowest extents of warm slab-top paths under blueschist facies conditions. Deformation microstructures show evidence of intragranular misorientation gradients and subgrain boundary formation that suggest deformation may be facilitated by dislocation creep. The seismic anisotropy (in AVp %) of the blueschist samples displays a general increase in magnitude with increasing volumes of glaucophane in the sample. The seismic wave velocity orientations (AVp patterns) can be divided into 2 main types: 1) Fast-velocity girdle in the foliation plane with slow-velocities normal to the foliation that corresponds to a glaucophane CPO with point-maxima in the a-, b-, and c-axes, and 2) Fast-velocity direction parallel to the sample lineation with a slow-velocity girdle normal to the lineation direction corresponding to a glaucophane CPO with the c-axis oriented along the lineation and a girdle formed by the a- and b-axes. VII. Abstract and References Blueschists show strong seismic anisotropy, scaling with glaucophane volume and fabric strength. This is likely a useful tool for imaging subducting slabs with receiver functions. V. Key Takeaways • The seismic anisotropy of mafic blueschists is largely controlled by the modal percentage of the amphibol | poster |

VIDEO ABSTRACTS: DO THE METRICS STACK UP? Tom Rees1, Sandra Lê2, Leigh Prevost1, and Sheelah Smith1 1PAREXEL International, Worthing, UK; 2Dove Medical Press, Macclesfield, UK Objective: Video abstracts offer a means to present results that complement the full paper. We aimed to compare video abstract views with other publication metrics in order to understand better the role they play in disseminating research findings. Research design and methods: Metrics were obtained from YouTube for all video abstracts published by the open-access publisher, Dove Medical Press. All articles with video abstracts published in four journals in different therapy areas over the period February 27, 2014, to March 19, 2015, were analyzed (average time since publication: 212 days), and compared with metrics for matched articles without video abstracts. Results: A total of 31 articles with video abstracts were identified. Average number of views per video was 364; most views came from United States, India, and United Kingdom. Males were 66% of viewers and 36% were aged 25–34 years. In our sample, video abstracts did not increase with time. Video views were weakly correlated with text abstract views (r-squared = 0.22) and with full paper views (r2 = 0.23) with around 1.5 video views per full paper view. Full views of papers with a video abstract were similar to those of papers without. Conclusions: Video abstracts are of interest to many authors and readers and complement full views. This is in line with authors’ and publication professionals’ views that publishing a video abstract increases the reach of research results and may increase downloads. UPDATED ABSTRACT • Video abstracts offer a novel means to present study results that can both complement and enrich the full published article. • Presenting results through a different medium could address the learning style preferences of a wider group. • In an accompanying poster, we present survey results that indicate high levels of interest from authors in video abstracts although concerns over impact and value were raised. INTRODUCTION • Video abstracts appear to be more popular with younger audiences. • The low correlation between video abstract, conventional abstract and full paper views suggests that they are reaching different audiences; however, video abstracts do not appear to replace or encourage full paper views. SUMMARY AND CONCLUSIONS • In this exploratory analysis, we aimed to compare video abstract views with other publication metrics in order to understand better the role that video abstracts play in disseminating research findings. OBJECTIVE RESULTS • Across the Dove Medical Press portfolio, the mean number of views per video abstract was 364.

Dust particles do not survive temperatures above 1000-2000 K, for which protoplanetary disks are cleared of dust close to the central stars. The size of such inner dust holes should be larger for more luminous (hotter) sources, ranging between ~ 0.01 and 20 au in optically-visible young stars. This range is critical for our understanding of planet formation, as it corresponds to the region where most exoplanets’ orbits lie1. In turn, those inner disk sizes translate to angular scales of milli-arcsecs even for the closest sources, and can be resolved mainly for intermediate-mass “Herbig Ae/Be” stars only by using near-infrared interferometry. Although previous interferometric studies have shown that there is a correlation linking the stellar luminosity of Herbig Ae/Be stars and the size of their inner dust disks, this “size-luminosity correlation” may change for early type Herbig Bes and shows considerable scatter2,3. The main physical scenarios proposed to explain the observed size-luminosity distribution are related to the presence/absence of innermost gas, different disk-to-star accretion mechanisms, or different dust disk properties as inferred from spectral energy distributions (SEDs)4,5,6. However, no general observational confirmation has been provided to date. Our goal is to identify the physical mechanism that drives the observed distribution in the size-luminosity correlation.

Department of Materials Science and Engineering, The Ohio State University, Columbus OH 43212 Program Objective • Toward the long-term goal of creating an integrated program for the design of complex disordered solids, this new project aims to develop a general, simulation- driven methodology for accurately recreating the atomic structure of substructure- containing amorphous solids and mapping resultant structures and properties back to fabrication conditions, ultimately enabling a computational design capability. • The work involves developing an ab initio molecular dynamics (AIMD) and hybrid reverse Monte Carlo (HRMC) simulation that is augmented by ab initio total energy and a set of geometric constraints. We will use a collection of thin-film amorphous preceramic polymers (a-BC:H, a-SiBCN:H, and a-SiCO:H) as suitably complex and technologically relevant case studies. • We develop novel algorithms for linking growth conditions and characterization information to atomistic simulation, and for mapping fabrication conditions to desired properties. Our modeling goal is to first identify non-global potential energy minima for material sub-components that are produced under non-thermodynamic conditions and to then align the timescales of the simulation and growth processes so as to generate realistic structural models of complex disordered solids. • The project combines state of the art computational techniques (AIMD, HRMC), modern optimization algorithms (e.g. artificial neural networks (ANNs), particle swarm optimization (PSO)), specialized experimental characterization techniques, (solid-state nuclear magnetic resonance (NMR), 4-dimensional scanning transmission electron microscopy (4D-STEM)), and advanced thin-film fabrication technology (plasma enhanced chemical vapor deposition (PECVD)). • The unique utility of modern solid-state NMR techniques to obtain specific bonding and connectivity information and the sensitive medium-range order information available from 4D-STEM will be combined with neutron diffraction and more routine physical/electronic structure characterization methods to provide input and constraints for the simulations. The project includes (left) growth and characterization, (middle) iterative modeling, and (right) design training and validation. Single-frame red boxes represent experimental samples and data, while double-framed blue boxes represent computational products. The shaded region in the middle represents the application of particle swarm optimization. The general flow can be understood as: (1) growth of samples varied by composition and growth procedures; (2) experimental structural characterization; (3) iterative model simulation using characterization data; (4) ANN training to link simulation and growth parameters followed by predictive application of the ANN. Acknowledgement To meet the long-term goal of developing an integrated program for the fabrication of complex disordered solids that are designed to satisfy the performance requirements of advanced applications, we set the following plans for the first year of this project. 1. We will form connections between experimental characterization and simulated data to guide the construction of realistic models of preceramic polymers. Our working procedure for generating individual models is to prepare the composition for a large-scale classical MD simulation via smaller scale AIMD and to then use HRMC to progressively improve matching between the mod | poster |

Therefore, DNA methylation profiling is important to reveal regions of the genome that are altered during development or that are perturbed by disease. Methylation signals at CpG sites can be assessed using bisulfite conversion method and massive sequencing technologies. Here we present the implementation of a bioinformatics pipeline for replication with MiSeq sequencing amplicons of the top hits obtained from Infinium 450K differential methylation experiments. CONCLUSIONS We have implemented a bioinformatics pipeline for replication of the top hits obtained from Infinium 450K experiments using MiSeq sequencing amplicons. For this purpose we have used well-established software for genome analysis as well as applications developed in our lab, all of them open source. The proposed workflow has proved to be useful for methylation level assessment while maintaining a good data quality control. Source code will be available at: https://github.com/pamag/DPMAS PIPELINE REPORT 450K results The assessment of methylation level at CpG sites from raw genetic sequences involves quality control and several processing steps. The main building blocks of the pipeline include SNP selection from 450K experiments, sequencing of the regions containing those SNPs with directional primers, mapping of the reads to the reference amplicon sequences and variant calling at cytosines in CpG sites. Finally, a dashboard report is produced as an analysis summary.

About the agreement To achieve the large-scale transformation towards open access, the project partners devised a “Publish and Read” (PAR) model with two components: The Projekt DEAL-Wiley agreement Significantly increased open access output from German research institutions. Enabled researchers from German institutions to easily publish their work open access, independently from available funding in their research areas, and retain copyright for their work. Expanded access to research findings for German institutions. Expand equal access to high-quality scholarly journals to all researchers in Germany. Analysis Wiley and the project partners are constantly monitoring the publishing output. Now that the agreement has been in effect for over two years,what are the actual changes in publishing and reading behaviour Wiley was able to observe? After the second year of this agreement, it is possible to draw the reasonable conclusions about impact and achievements: The two Key goals of the Projekt DEAL-Wiley agreement: Transitioning to an open future Wiley’s commitment to open access Empower all (corresponding) authors with the means to publish their articles openly. Gold Open Access increase in the number of Gold journal published articles from 2018 to 2020. increase the number of accepted and approved articles in 2020, compared to 2019. Hybrid Open Access increase in the number of articles published open access. of authors choose to publish OA in our journals of authors choose a CCBY license Open Access Publishing The Projekt DEAL-Wiley agreement has already made notable advancement towards a higher ratio of open access publications. articles published in Wiley’s hybrid portfolio between July 2019 and December 2020. articles published in Wiley’s Gold Open Access journals in 2019 and 2020. Outcomes: Reading accesses to full text HTML and PDF (2020). increase in usage since before the agreement. Participation and reach institutions where Readers have reading rights (2020). Publish component: • Authors publishing in Wiley’s 1,400+ hybrid journals may publish OA at no direct cost to them; Projekt DEAL pays a PAR fee of 2.750€ to Wiley per such article • Authors can publish in 230+ fully gold open access journals at no direct cost*, and institutions get a 20% discount on the Article Publication Charge (APC). Read component: • Participating institutions gain free read access to more than 1,600 Wiley journals (dating back to 1997) Outcomes: Introduction In January 2019, Projekt DEAL, a consortium representing German research institutes and academic libraries, signed a large-scale open access agreement with Wiley, publisher of over 1,600 peer-reviewed journals from all areas of research. Its goal was to accelerate the nation-wide transition from a predominantly subscription- based publishing model to one based on open access. It is intended to significantly raise the number of open access articles being published out of German research institutions while securing, and even expanding institutions’ read access to Wiley’s journal output at the same time. >1000% 92% 15,716,977 49% 495 58% 92% + 14,500 + 1,500 Participation and reach institutions where eligible authors have open access publishing rights.

MESA solves the 1D fully coupled structure and composition equations governing stellar evolution with implicit finite volume scheme. State-of-the-art modules provide adaptive mesh refinement, sophisticated timestep controls, non-adiabatic oscillation capabilities, equation of state, opacity, nuclear reaction rates, element diffusion, boundary conditions, and changes to the mass of the star. MESA has significant penetration in the astrophysics community and is well on its way to becoming the world standard for evolving stars, providing a crucial resource to the astrophysical community at just the right time. The third year of our SI2-SSE award has been key to sustaining MESA as an essential piece of software infrastructure while building new scientific and educational networks. • software instrument papers MESA I (2011), MESA II (2013), and MESA III (2015) have collectively been cited over 1000 times.

Bringing Interoperable Annotation to All Scholarly Works Annotating All Knowledge Coalition and Working Group A coalition of some of the world’s key scholarly publishers, platforms, libraries, and technology organizations are coming together to create an open, interoperable annotation layer. Web annotation is here! Our goal is to make it pervasive across scholarship, open and interoperable. For decades web pioneers have imagined a native and universal collaborative capability over the Web. Many projects have experimented with it, yet in 2015 we’re still stuck with the same patchwork of proprietary commenting systems, only available in some places. In the last few years a growing community has been working to change that. Our goal is to standardize “annotation” as a unit of conversation built into the very fabric of the Web. In late 2014 the World Wide Web Consortium (W3C), the standards body for the Web, established a formal Working Group to support this standards effort. Much progress has been made, and many implementations are now mature enough to be deployed. What’s possible with web-based annotation? Make persistent annotations in texts by highlighting passages, adding notes, and tagging with keywords.

We studied magnetic properties of basalts with different field dependences. We found the field dependence behavior is associated with Hopkinson peaks. High field-dependent basalts are characterized by reversible thermomagnetic curves and low Curie temperature and should be better treated with AF demagnetization.
