Exploring the Mass-Metallicity Relation in Open Clusters inside the Milky Way S M Rafee Adnan1,2, Ahmad Al- Imtiaz1, Sumit Roy Pronoy1,3, Anock Somaddar1, Syed Badiuzzaman Faruque1 1 Shahjalal University of Science and Technology, Bangladesh, 2 University of Louisville, Kentucky, 3 Daffodil International University, Bangladesh Background & Objective Open clusters (OCs) provide a controlled setting to investigate the interplay be- tween mass and metallicity on a more localized level. However, the specific anal- ysis of this relation within individual open clusters has been sparsely investigated, despite its significance. In this study, we aim to fill this research gap by conducting a comprehensive analysis of 75-star clusters, with the objective of examining the trends and probing the underlying mechanisms governing their mass-metallicity relationship. Data Collection The majority of the OCs reside within ∼1700 pcs thus belonging to the Milky Way galaxy. Hence, most of the selected cluster members will be lying in the main sequence of the HR diagram. APSIS utilizes the extensive data collected by the Gaia spacecraft, including mean RVS spectra and mean BP/RP, positional measurements, parallaxes, and photometric data for up to 470 million sources. Seabroke et al. (2022) offer a comprehensive and in-depth explanation of the RVS data and its processing methodology. APSIS derives a range of astrophysical parameters for stars, including stellar spectroscopic and evolutionary parameters, such as mass (M) (140 million), metallicity [M/H] (6 million using RVS, 470 million using BP/RP). We mainly used the following data for our analysis. parallax, pmra, pmdec We used the parallax and proper motions for determining the members of OCs using HDBScan. mass_flame We used the star’s mass, obtained from FLAME. This value was derived by comparing the teff_gspphot and lum_flame measurements with the BASTI stellar evolution models for solar metallicity, as described in the study by Hidalgo et al. (2018). mh_gspphot We also employed the decimal logarithm of the iron-to-hydrogen number abundance ratio, compared to the corresponding ratio of solar abundances determined by GSP-Phot Aeneas. This determination was based on analyzing BP/RP spectra, apparent G magnitude, and parallax, assuming the source to be a single star. Methodology: Member Selection HDBSCAN is a clustering method that considers all values and constructs a hier- archical tree, integrating multiple results. HDBSCAN was run on each dataset that came back from the ADQL Gaia DR3 query. 0.0 0.5 1.0 1.5 2.0 2.5 3.0 GBP GRP 5.0 2.5 0.0 2.5 5.0 7.5 10.0 12.5 15.0 G (mag) All sources NGC_2682 Figure 1.

Spatial distribution of NGC 2682 In cases where HDBSCAN failed to identify a cluster, we employed an iterative approach by modifying the parameters and reattempting the clustering process. Methodology: Curve fitting After determining the members of an Open Cluster (OC), we plotted metallicity vs. mass and fitted a model for each of the OCs. A non-linear curve fitting was performed using MCMC with the emcee library. A model representing the relationship between the mass and metallicity variables was defined as: y = x + d |x + d| (x + d)b + c (1) Here, x and y represent for mass and metallicity, respectively. And b, c, d are constants. Multiple walkers were initialized with random parameter values and moved through the parameter space, guided by the likelihood function. Param- eter estimates and uncertainties were obtained from the converged walker po- sitions. The equation we used above is based on the findings of Leethochawalit et al. 2018. They found that the mass metallicity relation of galaxies follows a power-law relationship. Here is the following equation: [Fe/H] = [Fe/H]0 log[1 + M∗/M0]γ (2) where [Fe/H] is the metallicity, M∗is the mass of the star, [Fe/H]0 is a normal- ization con

Introduction: Lilah Nuggets of Hope: Using coral microfragments to determine best practice reef-rebuilding techniques Katelyn Cambridge, Sophie Cappello, Jack Kenney, Henry Kuck, Haya Firas, Austin Anderson Advisors: Valeria Pizarro and Lily Haines – Interns: Hannah Lochan and Eliza Thomas Introduction Objective Methods Results and Discussion Take-home Messages References Acknowledgments Staghorn and Mountainous star : • Nursery was most effective, with the fastest growth rates • Reef treatment showed a decrease in healing due to fragments experiencing predation or being swept away by the current Massive starlet: • Wetlab treatment was most effective, with the fastest and steadiest growth rates as well as the highest average wound healing. • Other two treatments fluctuated, showing decreases in wound healing at various points. We hypothesize that this is because massive starlet fragments struggled with algae overgrowth therefore having them in the wetlab allowed us to access and clean them more easily 0 20 40 60 80 100 1 2 3 4 5 6 0 20 40 60 80 100 1 2 3 4 5 6 Nursery Reef Wetlab 0 20 40 60 80 100 1 2 3 4 5 6 Coral reefs are coastal marine ecosystems that cover less than 1% of the ocean floor but are necessary habitats for 25% of all marine species. Many factors contribute to the degradation of coral reefs a few include pollution, climate change, legal but unsustainable fishing and the introduction of invasive species such as the lionfish. Coral restoration is the process of assisting the recovery of coral reefs. (Edwards & Gomez, 2007). micro- fragmentation is a new coral restoration technique that has never been done before in the Bahamas. Collect 10% of coral head Cut into 1cm2 fragments Grows exponentially faster Outplant The coral reef health is declining throughout the Bahamas (Dahlgren et al., 2016). The reefs are deteriorating with most of our reefs being impaired and in poor condition. A healthy coral reef should have a coral coverage over a reef of over 30%. However, in the Bahamas, coral cover is lower than 15%. Which treatment setting: coral nursery, wetlab, or open-ocean reef, best promotes the survival, wound healing and health of three coral species for a coral restoration project? • Staghorn coral and Mountainous star coral showed the best health, healing and growth in the nursery tree. • Massive Starlet coral showed the best health, healing and growth in the wet lab. • The Starlet microfragments had the highest algae coverage, suggesting that the species might not be ideal for restoration work in the Bahamas. • The reef isn’t a suitable environment for growing microfragments of any of our species. This indicates that the microfragments need to grow a bit bigger so they’re less vulnerable before out-planting them on the reef. This is the first time microfragmentation on these three species has ever been done in the Bahamas. This type of restoration has the potential to make Bahamian coral reefs more resilient to human-caused stressors in the future. This knowledge will help upscale and improve restoration efforts at CEI and the Bahamas as a whole.

Preserving Biodiversity with IrisBG and ESRI Laura Knutson Murray1, Mari Rustan2 1Magnolia Maps, , USA, 2IrisBG, , Norway “The loss of biodiversity is permanent, with climate change one of the factors leading to this loss. We have about 12 million species on earth—not counting bacteria and other microorganisms—and we have given names to fewer than two million… Despite this gaping hole in our knowledge, we must act to preserve as many of the existing species while there is still time to do so.” - Dr. Peter H. Raven, President Emeritus of the Missouri Botanical Garden Tracking biodiversity, through documenting living plant collections, requires constant attention to detail as plants change and grow and their environments change or can be modified. For over 25 years, IrisBG has refined a software and database solution for all aspects of managing living and preserved botanical collections. IrisBG facilitates everyday work with living and preserved botanical collections and enables easy accessioning with images and mapping, sharing of plant material, tracking the wellbeing of plants and much more. When synchronized with ESRI’s suite of cartography products, users have an even more powerful set of applications that can be customized for their institution and used on any device for internal use or publicly shared. Mari Rustan of IrisBG and Laura Knutson Murray of Magnolia Maps will walk attendees through a live demonstration of how the Memphis Botanic Garden is creating digital records and sharing their collections with the world.

Three dimensional (3D) models offer significant improvements over traditional two dimensional monolayer cell culture in terms of maintaining morphological and functional characteristics of tissue, and may provide a better representation of in vitro drug toxicity1. Here we demonstrate how Corning HepatoCells, an immortalized alternative to primary human hepatocytes, in conjunction with Corning Spheroid Microplates can be a utilized for a 3D drug screen to discover potential hepatotoxins. Hepatospheres formed using Corning HepatoCells were compared to spheroids formed using alternative hepatocyte-like models. Cell viability, urea and albumin were measured to assess hepatotoxicity after exposure to the SCREEN-WELL Hepatotoxicity library from Enzo Life Sciences, a library consisting of 238 compounds with a variety of structurally and mechanistically different compound classes, as well as nontoxic controls. Selected hits identified in the 3D screen, which significantly reduced cell viability of the hepatospheres, were then assessed in a dose-dependent manner for potency analysis. These results demonstrate that Corning HepatoCells, together with Corning Spheroid Microplates, are powerful tools that can be used for reliable and reproducible 3D hepatotoxicity screening. • Corning spheroid microplates allow for the formation of consistent sized, single spheroids in each well, available in both 96 and 384 well formats, making them a useful tool for 3D screening. • Hepatospheres formed using the Corning spheroid microplate are amenable to histological analysis. • The opaque walls and clear, round well-bottom of the spheroid microplates allow for luminescent assays to be conducted in the plate without the need for a transfer step. • HepatoCells offer an ideal hepatic cell alternative to commonly used HepaRG cells, offering a larger assay window for luminescent ATP assays, which is amenable to screening. • HepatoCells displayed increased or equivalent sensitivity to known hepatotoxins tamoxifen, troglitazone and nicardipine upon potency analysis, compared to HepG2 and HepaRG cells. Representative photomicrographs of HepatoCells,HepG2, and HepaRG spheroids after 7 days, seeded at 6,000 cells/well, 200 cells/well, and 6,000 cells/well respectively (40x). Spheroid Size Optimization HepatoCells (Corning Cat. No. 354881), HepG2 cells (ATCC® Cat. No. HB-8065), and HepaRG™ cells (Life Technologies Cat. No. HPRGC10) were seeded at various concentrations in 384 well spheroid microplates (Corning Cat. No. 3830) to optimize for the subsequent screens. HepatoCells and HepG2 cells were seeded using 50 µL Corning Culture Medium for HepatoCells (Corning Cat. No. 354882) containing 10 % fetal bovine serum (Corning Cat. No. 35-010-CV). HepaRG cells were seeded using William’s medium (Life Technologies Cat. No. 12551-032) supplemented to 1x with HepaRG Thaw, Plate & General Purpose Medium Supplement (Life Technologies Cat. No. HPRG670) and 1x GlutaMAX (Life Technologies Cat. No. 35050-061). Medium was changed every other day using

Int J Public Health. 2016;61(2):167-175. doi:10.1007/s00038-016-0787-y References P-17 Electronic cigarettes (e-cigarettes) is growing a public health concern because its present threats to tobacco control and undo the success achieved. E-cigarettes and vaping are seems to be in trend nowadays especially among adults regardless of the negative health impacts. This study aimed to investigates the current prevalence of e- cigarette users and its associated factors among adults aged 15 years and above in Malaysia. • There was almost equal representation of male and female respondents from 11,111 respondents aged 15 years and older. • The prevalence was signiﬁcantly highest among Malay and others ethnicity (5.8%), younger age group 15-24 years (11.2%) ,private employee (7.3%) and among current smoker (15.5%). • Current e-cigarette users were associated with male (aOR= 26.71;95% CI= 14.79, 48.23), 18 to 24 years old (aOR= 10.80; 95% CI= 7.22, 16.13), and current tobacco smoker (aOR=2.51, 95% CI=1.98, 3.17). • From other study among university in students in Malaysia done by Sharifa et al, it showed that 74.9% of the students smoke and 40.3% were cigarrette smokers too . • In 2011, a Global Adult Tobacco Survey was done in Malaysia and the current e-cigarettes user among adults at that time was 0.8% . • The prevalence of smokeless tobacco products including e-cigarette use among adult in Malaysia was 10.9% but that was including other types of smokeless tobacco products . • The current e-cigarettes smoker in Serbia was reported to be 2% which is lower than our national prevalence • Data from the National Health & Morbidity Survey (NHMS) 2019 conducted by Institute for Public Health, Ministry of Health was analyzed. • It is a cross sectional, population-based survey which employed a two-stage stratiﬁed cluster random sampling design to ensure national representativeness. • Sample consisted of 11,111 respondents aged 15 years and above responded to the smoking module. Respondents were given structured questionaires via face to face interview. Descriptive and multivariate analyses were used for analysis.

S., PCCP, 2013, 15, 19478-19486 Introduction An efficient dye sensitized solar cell (DSSC)[1,2] is one possible solution to meet the world’s rapidly increasing energy demands and associated climate challenges. This requires inexpensive and stable dyes with well-positioned frontier energy levels for maximal solar absorption, efficient charge separation, and high output voltage. Here we demonstrate an extensive computational screening of 1029 zinc porphyrins systematically functionalized with electron donating side groups and electron accepting anchoring groups. The trends in frontier energy levels versus side groups are analyzed and a no-loss DSSC level alignment quality is estimated. All frontier energy levels, gaps and level alignment quality values are stored in a database publicly available.[3] Dye Sensitized Solar Cells Building blocks Conclusions By systematically changing the side groups and anchor groups of zinc porphyrin dyes we obtain a handle to control the frontier orbitals and the level alignment to match the requirements for Dye Sensitized Solar Cells which may be used to improve the efficiency. Computational methods • Density Functional Theory with PBE in the GPAW code. • Geometry optimization of all candidates. • Fundamental gaps using total energies. • Triplet excitation energies used to compute the level alignment quality.

The main characteristic of this method is that the grain boundary diffusion of the sample is maintained, while also avoiding grain boundary migration. Therefore, the grain growth associated with the final step of the sintering process is completely suppressed. Two-Step Sintering Process Commercially available ZnS powder (a mixture of 80% cubic and 20% hexagonal phase) was used as the starting powder, without any binder or sintering aid. Discs with a diameter of 8 mm and a thickness of 4 mm were prepared by uniaxial pressing at 100 MPa, followed by cold isostatic pressing at 150 MPa. Advantages  Finer microstructure  Sintering temperature reduction  Simple and pressureless method  Large-scale production of components with complex shapes  Binders not necessary  Lower costs The amount of solvent remained the same (60 ml of ethyl glycol) by re-using what remained of the solvent used in the previous reaction and topping up the quantity lost. Productivity yields increased over six successive reactions from 156 mg to 549 mg of ZnS nanopowder per batch. Self-alignament of ZnS nanopowder dispersed in ethanol, after being washed several times in acetone and ethanol. Take a picture to download the full video “Circular synthesis”: By recycling a used solvent obtained from previous reactions and topping up the quantity lost, the productivity yield increased 3.5 times. Method: The well-known reaction of ZnCl2, as the zinc source, with thiourea as the sulphur source, dissolved in ethyl-glycol at a carefully controlled, constant molar ratio (mMZn/mMS=1) under medium temperature conditions (140°C-150°C). The next step is using recycled ZnCl2, to make the synthesis fully circular.

A possible solution: Increase the second step holding time. • The first step in the TSS processing of prepared ZnS nanopowder at T1= 1250°C did not prove successful. The next step is to improve the densification, using a higher compaction pressure to prepare the green body (200 MPa isostatic pressure) and heating it to a lower T1 (of around 1000°C).

The 7th International Symposium on Gas Transfer at Water Surfaces Seattle, WA USA May 18-21, 2015 Flow field and momentum balance in the Heidelberg Aeolotron, a large annular wind/wave facility M. Bopp1 and B. Jähne1,2 1 Institute of Environmental Physics (IUP), University of Heidelberg, Germany, maximilian.bopp@iup.uni-heidelberg.de 2 Heidelberg Collaboratory of Image Processing (HCI), University of Heidelberg, Germany, bernd.jaehne@iwr.uni-heidelberg.de The Heidelberg Aeolotron is an annular wind/wave facility with 10m diameter. One of the main advantages in contrast to a linear facility is the nearly infinite fetch. The conditions on the water surface, and so the gas transfer are more similar to conditions at the open ocean. The wind field in the Aeolotron was investigated with a pitot tube mounted on a translation stage. The radial wind speed was measured for a complete cross section at ten positions. To measure near the water surface surfactants were added to dampen the wave field. As expected the wind generators, two axial fans embedded in the ceiling, and the annual geometry of the facility produce a flow pattern shaped like a half helix between the fans. This results in variations of the wind speed near the surface, which are about 30% at the measured wind condition. Figure 1: The friction velocity determined by the momentum balance method for clean water (crosses) and two concentrations of the surfactant Triton X-100 (circles and stars) in dependence of the reference wind speed.

Se suele presentar junto a una fístula traqueoesofágica, clasificándose en cinco categorías según la presencia o no de la mencionada fístula. La variante más frecuente es la atresia esofágica tipo C, es decir atresia fístula traqueoesofágica distal, que corresponde al 85% de los casos descritos de la misma, en segundo lugar, tenemos a la atresia esofágica tipo A, la cual corresponder a atresia esofágica pira, sin la presencia de fistula, con solo 10% de prevalencia, muy alejada de las más común tipo C, anteriormente mencionada. El diagnóstico puede realizarse prenatalmente mediante evaluación de antecedentes obstétricos y hallazgos en ecografías, así como también postnatalmente mediante la observación de síntomas como intolerancia a la alimentación y excesiva producción de secreciones orales. Todo esto, claro está debe ser confirmado mediante radiografía de tórax que evidencia la imposibilidad de pasar una sonda nasogástrica a través del esófago, junto a presencia o no de aire en cámara gástrica, lo cual nos ayudará a discernir en la presencia o no de fistula. El tratamiento principal, por supuesto será de naturaleza quirúrgica. El pronóstico es generalmente favorable, las complicaciones se relacionan con el período postoperatorio y a largo plazo.

In particular, the customization of food products, such as 3D cakes, is performed by skilled operators with problems in ﬁnding them in peak production periods. Fortunately, text and drawing decorations can be translated into trajectories that can be followed by industrial robots, thus making it possible to fulﬁll the same task. However, the redundancy of the task and the synchronization with the external equipment, such as conveyors, make trajectory planning particularly demanding. In this paper, an optimization technique that considers all these parameters is presented, which allows to reduce cycle time and therefore energy consumption. Index Terms—Robot, redundancy, path planning, food industry I. INTRODUCTION The market demand of 3D cakes and of big chocolate struc- tures is rapidly increasing [2]. Unfortunately, the operation of writing customized text/drawing decorations over cakes using melted chocolate or icing is now performed by skilled staff, with problems in ﬁnding them in peak production periods. Nowadays several 3D food printers have been developed [1], [3], [6], [8], but also conventional printers with edible ink have been used [3]. However, the usual application of food customization relies on small adjustments of the ﬁnal product: small drawings, different text and similar. This is particularly true in cake industry, where the cake can be personalized by adding a person or a company name. This small adjustments do not justify a high investment cost of a dedicated machine, but need a fast equipment that is easy to reconﬁgure for each single product. Industrial robots seems to be perfect for this purpose [4], [5]. Text and drawing decorations can be easily transferred to the robot by deﬁning speciﬁc viapoints to be interpolated. These viapoints form a trajectory that reproduce the personalized element to be printed on the surface of the cake. Each viapoint is described by n parameters (required to deﬁne its position and orientation in space), but the task itself This work is partially supported by EPSON Robotics within the Win-a- robot Contest of 2018 is redundant: each position can be reached by rotating around the surface normal, thus there are inﬁnite robot conﬁgurations [7] that can fulﬁll the task. Even if this redundancy can be exploited by the last joint rotation, the equipment is usually too big to be installed aligned with the last joint axis, so its installation is required to be off-axis. As a result, the aforementioned redundancy affects all joints value. In this paper, an optimization technique that takes care of the redundancy is developed. To further improve the work, a linear conveyor is included in the workcell: this aspect will show how our solution could be ready for a real industrial scenario with a high throughput. II. OPTIMIZATION TECHNIQUE Let’s consider a trajectory f(x(t)) that expands in 3D space on a surface. This trajectory can be discretized in multiple via points to be used in the robot path planning. If the robot is redundant, so the number of parameters required to uniquely deﬁne it conﬁguration are more than the degrees of freedom of the structure, inverse kinematics results in inﬁnite possible solutions. That’s said, for each point the joint values are a function of the Cartesian position x and the redundant parameters values: q(t) = g(x(


Exploring the Nature of the Hard X-ray/ Soft Gamma-ray Emission of Cen A James Rodi1, Elisabeth Jourdain2,3, Jean-Pierre Roques2,3 1INAF-IAPS, Rome, Italy; 2Universite de Toulouse, Toulouse; 3CNRS, Toulouse Above: Cen A 20—40 keV and 100- 200 keV light curves on revolution timescale. SPI (black) and ISGRI (red). Sides: Photon index vs 50 keV flux for obs close in time with SPI (left) and ISGRI (right). Best-fit to a constant photon index shown as red dashed line. Centaurus A Introduction: As one of the brightest radio-loud active galactic nuclei (AGNs) in the hard X-ray sky (Beckmann et al. 2009), Centarus A (Cen A) has been observed by numerous missions since its first detection in 1969 (Bowyer et al. 1970). Results have shown that the spectral shape does not vary with flux (Jourdain et al. 1993; Rothschild et al. 2006; Beckmann et al. 2011; Rothschild et al. 2011; Burke et al. 2014). Consequently, one would expect reported spectral parameters for Cen A to be similar across time and instruments. Yet that has not been the case as there has been a lack of consistency in the values, which has made interpreting the origin of the hard X-ray/soft gamma-ray emission difficult. From the past ∼30 years, the main disagreement is over the presence of spectral curvature at high energies. In general, X-ray analyses favor models without spectral curvature below ~1 MeV (Rothschild et al. 2006, Rothschild et al. 2011, Furst et al. 2016). However, analyses up to soft gamma-rays show evidence of curvature, though where the curvature is varies (Jourdain et al. 1993, Steinle et al. 1998, Beckmann et al., 2011, Burke et al. 2014). The existence of curvature and where it is is critical to understanding the emission process at work in Cen A. Additionally, recent Swift/BAT results show spectral variability after 2013 with the source spectrum steeper when the source is brighter and harder when the flux is lower (Rani et al. 2022). Data Analyses: We analyzed SPI and ISGRI archival data and observations from the current AO to span the full INTEGRAL mission, revolution 48- 2539 in the ~20 keV – 2 MeV energy range using SPIDAI and the most recent version of OSA, respectively, for a total exposure time of ~ 5 Ms each. During this time, Cen A underwent a range of fluxes that enable searches for spectral-flux variability and also investigate the presence of high-energy spectral curvature. ABSTRACT: Despite decades of observations, the nature of the hard X-ray/soft gamma-ray emission of Cena, the brightest radio-loud AGN in the hard X-ray sky, is still unclear. The two main competing models are thermal Comptonization and synchrotron self-Compton emission. They predict a spectral cutoff of roughly 300 keV or > 1 MeV, respectively, and require spectral coverage to the MeV region to differentiate. Using archival data and observations from the current INTEGRAL AO, we investigate Cen A's spectrum using both SPI and IBIS/ISGRI to better understand the soft gamma-ray emission and the process at work in that energy range. Also, we search for spectral variability in light of recent results from Swift/BAT. We find that INTEGRAL spectra can be described by either a cutoff power law model with Ecut~550 keV or by a log parabola model. Results & Future Work Results: To start we looked for spectral variability by fitting observations close in time to power-law models in the 25-70 keV energy range for SPI and 30-70 keV for ISGRI. The results for each instrument are shown in plots above. Each set of photon indexes were fit to a constant value to test for spectral variability. The best-fit constant for each instrument is plotted as a red dashed line. For SPI the best-fit photon index is 1.70 +/- 0.03 for SPI and 1.83 +/- 0.01 for ISGRI with red. chi2 values less than 1 for each with all the data points within 3-sigma from the average value thus the data are consistent with a constant photon index. However the best-fit indexes for each instrument are significantly different. T


A participatory approach to invent the future of mobility CCM: An open purpose driven ecosystem with an Action driven approach Eveline Wandl-Vogt Ars Electronica Research Institute “knowledge for humanity” Austrian Academy of Sciences In spring 2019, various people from the mobility sector started to build a free and open mobility community. It represents a multistakeholder core of an emerging mobility ecosystem, an open system consisting of more than 80 organizations from industry, start-ups, science, civil society and many other committed mobility thinkers from DACH countries. A so-called orchestrator group is directing the processes. They are not determining the rules and processes in the system. The members of the group come from stakeholder organizations. Nevertheless, a company or organization - as in our ecosystem www.mobility.community - has to give the go-ahead for the ecosystem and the formation of an orchestrator group: In our case it was the Austrian Federal Railway with its Open Innovation Team. The initiating organisation has a greater effort, for example for the coordination by its own employees. In the same way, the initiator has also increased responsibility due to the greater scope for influencing the further development of the ecosystem. That is why we have set up the orchestrator group broadly, with mobility people from startups, EPUs, universities and other companies. And the state? Getting politicians and administrators involved is essential! And we did this using the example of the car-free city center of vienna. Now we have to focus on mobility customers! So that we don't become an introverted bubble of ideas , formerly “ivory tower”.

How the stellar flicker noise affects the characterization of planetary transits ? S. Sulis1, M. Lendl2,3, S. Hofmeister3,4, A. Veronig3,4, L. Fossati3, P. Cubillos3, and V. Van Grootel5 ABSTRACT How flicker impacts the inferred planet radius ? Predictions for PLATO Stellar activity is known to limit exoplanet detection and characterization. Among this activity, stellar convection (``flicker'') evolves during the typical transit timescales (~ hours) and affects the inferred transit parameters. We generated realistic simulations of transiting exoplanets based on solar HMI data. These simulations include planets from 1 to 10 Earth radii with different transit geometries. These simulations comprising hundreds of light curves are available to the community : https://doi.org/10.5281/zenodo.3686871 We analyzed the data using standard MCMC methods assuming the noise is white and Gaussian (WGN), or a Gaussian Process (GP). We show that, in both cases, the resulting planet parameters can be affected by biases, which leads to biased planetary radius measurements. This demonstrates the need to develop robust stellar noise modeling to achieve PLATO's goal of characterizing exoplanets transiting solar-like stars. Next steps of this study will be to investigate i) how other noise sources (e.g., flares, spots and faculae) affect the inferred exoplanet parameters, ii) which noise modeling allows to derive the most accurate transit parameters. The flicker index : a new indicator to track the flicker noise We developed a new indicator to track the granulation noise properties in photometric light curves: the flicker index. It is defined as the slope of the periodogram measured in the frequency range where granulation dominates (e.g., from 8 to 30 min for the Sun). Based on the observed correlations, we predicted for which stars this noise source is expected to be significant enough to impact the characterization of Earth twin transits observed with PLATO (24 camera). For example, we expect the flicker noise to significantly impact the light curves of all solar- type stars with apparent magnitude <13 (dashed contour lines in Fig.4). This indicator informs on the noise amplitude, characteristic frequency and correlation type. Based on hundred of Kepler light curves, we found it is correlated with the stellar parameters (Fig.3). Stellar granulation (and oscillations) signals can reach several tens of ppm. When single transits are observed : this nuisance signal biases the transit parameters. We have done simulations of synthetic exoplanet transits on quiet solar data (Fig.1) to quantify this bias. Based on classical characterization MCMC algorithm (assuming the noise is a WGN), we found bias in the inferred planet radius that can reach 12% (blue histograms, Fig2). Simulating similar light curves, but with true WGN, led to error models << 3% (see red histogram). Based on more complex flicker noise modeling (GP), the errorbars on the transit parameters are larger, but the unpredictable bias remains. 1 Univ. Aix-Marseille, LAM, France, 2 Obs.

Inference on Individual Differences in Functional Imaging: A test for correlations among tasks Sumitra Purkayastha   , Tor D. Wager  and Thomas E. Nichols   Bayesian and Interdisciplinary Research Unit, Indian Statistical Institute, Kolkata 700108, INDIA,  Department of Psychology, Columbia University, New York, NY 10027, USA,  Department of Biostatistics, University of Michigan, Ann Arbor, MI 48109, USA Objective Complex experimental designs often yield multiple measurements of interest on each subject. For ex- ample, a   factorial design will yield contrasts for each of  subjects. When analyz- ing all  measurements together at the sec- ond level, the problem of inter-task dependence or “non-sphericity” must be accounted for. SPM ([1]) treats the inter-task correlations as nuisance param- eters, estimating an inter-task covariance and adjusting the inferences accordingly ([2]). However, correlations among tasks are of great theoretical interest in psychological studies, because they provide information about how tasks are related to one another. Hence the goal of this work is to ana- lyze inter-task correlations as parameters of interest, not simply as nuisance parameters. Speciﬁcally, we wish to detect pairs of effects where a high response in one effect predicts a high (or low) response in the other effect. This kind of information in human per- formance is the basis of arguments for general fac- tors underlying mental abilities (e.g., Spearman’s G) but has seldom been applied to brain imaging data. Working with a two-level model for fMRI data, we estimate the matrix of correlations between at each voxel and create statistic maps that detect the presence of non-zero correlation across differ- ent tasks. Then using scatterplots and the individual correlations, we assess and interpret speciﬁc patterns of dependence. We demonstrate our method with a fMRI study of attention switching. Methods We work with the following two-level model for fMRI data for  subjects:      N "!$# % '& )( +* , -)- -)    ./  /  N 01!2# 43 ( 5* , -)- -)    -)- -) 476 /  -)- -) 4/86 are independent - !9,:( In (1),   is of length ; , the number of scans. The ﬁrst level models the fMRI data for the * -the individ- ual and the second level models the population mean  (a length- < vector) while allowing for a nondiago- nal covariance 3 . We wish to test if the covariance matrix of a set of contrasts of the vectors of activation coefﬁcients is diagonal. We assume that the within- subject variability %  is known, which is reasonable since ; is generally large and consequently an accu- rate estimate of % can be obtained. Allowing some possible loss of information, we work with the following modiﬁed formulation of this problem. To begin with, we assume that    for all * . Denote by = , the < ma- trix whose rows give the contrast vectors. We pre-multiply both sides of the ﬁrst equation of (1) above by > ?9@BA =C!D T E(GF  T and both sides of the second equation by = and obtain a transformed two-level model. The observations in the ﬁrst-level are given by H  ?9@BA >   and the regression pa- rameters corresponding the two levels are given by I  ?9@BA =   I ?9@BA = J- The vectors H  I  I are all , . The covariance matrix in the second-level is given by KL = 3 = T - It is possible now to formulate our question in terms of K . We want to test the following: H M+NOK is diagonal against H NOK is non-diagonal. !  ( In this initial work, we will assume that we have an orthogonal design. That is, we assume that the < contrast estimators are independent, speciﬁcally that P ?Q@A =C!D T E(RF = T is diagonal. With this assump- tion, any correlation observed in H  at the second- level is attributable to population-level inter-task cor- relation. In this case we can use Bartlett’s modiﬁca- tion ([3]) of the relevant Likelihood Ratio Test (LRT) ([4], pp. 137-138) as an ad-hoc solution. However, when the d


Translational control of fatty acid synthesis controls nuclear division during the cell cycle Nairita Maitra, Heidi Blank, Clara Kjerfve, Vytas Bankaitis, Michael Polymenis Texas A&M University, Department of Biochemistry and Biophysics, College Station, TX 77843 • Lipid synthesis during mitosis is essential for both human cells and yeasts. From our recent mass spec study on budding yeast, we found that among all other metabolites, the abundance of lipids is the highest late in the cell cycle. However, how the lipid homeostasis is maintained during the cell cycle is not understood. • Given the involvement of lipids in cancers and other diseases such as cardiovascular disease, obesity, diabetes, etc., it is important to study the regulation of lipids during the cell cycle. Moreover, higher levels of lipogenic enzymes are indicative of poor prognosis of different cancers. • Fatty acids are the building blocks of lipids. A genome-wide study performed in budding yeast in our lab showed that the translational efficiency of mRNAs encoding two major fatty acid synthesis enzymes, acetyl CoA carboxylase (ACC1) and fatty acid synthase (FAS1) peaks late in the cell cycle. Here, we show that the higher translational efficiency of ACC1 and FAS1 not only alters the abundance of different lipid species but also significantly promotes nuclear division during mitosis. • Taken together, our data link core metabolic functions of lipogenic enzymes (Acc1p and Fas1p) to the morphological changes of the nucleus during cell division.

Introduction The oxidation resistance of polycrystalline nickel-based superalloys is afforded by the chromium content of the alloy resulting in the formation of an external, protective, thermally grown chromia (Cr2O3) scale. The oxidation kinetics of nickel-based chromia forming alloys have been well documented in the literature [1-7]. Differences of several orders of magnitude have been observed in oxidation rates between different chromia forming alloys. These differences have been attributed to differences in surface finish, the amount of cold work in the alloy, grain size, and oxidation environment. The coarse-grained variant of the RR1000 alloy has been extensively studied in a polished and shot-peened surface condition[1, 2, 7]. In the coarse-grained variant of the alloy shot-peening was reported to be detrimental to the oxidation properties[2]. This work extends the study of this alloy to include the fine-grained variant and at a lower temperature (650°C) where no recrystallisation was expected.

We estimate that NGC 2264 contains 200-600 brown dwarfs in the mass range of 0.02-0.08 M☉and determine the slope of the sub-stellar mass function to be 𝛼= 0.43!".$% &".'(. These values are consistent with those measures for other young clusters. This points to a uniform sub- stellar mass function across all star-forming environments. Results The origin of brown dwarfs and the substellar mass function have long been subjects of debate. The perquisite for making progress on these issues is to have large and well characterised samples of young brown dwarfs in diverse star-forming regions. NGC 2264 is an ideal region to achieve this due to its large population of ~1500 stellar members, relative proximity of 719 ± 16 pc, and low foreground extinction. NGC 2264 provides a perfect laboratory to study star and brown dwarf formation. Introduction We have used deep multi-wavelength, multi- epoch data to build a catalogue of brown dwarf candidates in NGC 2264. Our brown dwarf candidates were initially identified by their near-infrared colours but were also required to display additional indications of youth, including variability, the presence of a disc, Gaia kinematics, rotation period and extinction. We used KMOS on the VLT to obtain follow up spectroscopy for a small sub- sample of our candidates in order to determine their spectral type, extinction and the confirmation rate of our candidates. Methodology The first spectroscopically confirmed brown dwarfs in NGC 2264 arXiv:2108.07633 The slope of the substellar mass function is 𝛼= 0.43 for a power law of the form !" !# ∝𝑚$% The majority of our confirmed brown dwarfs are very young (<0.5 Myr) Using indicators of youth significantly improves spectroscopic follow up efficiency. The substellar mass function for the three KMOS fields in NGC 2264 (see below figure), represented with three equally size log-mass bins in the range of 0.02-0.08 M☉.

The three fields that were observed with KMOS/VLT are overplotted in white. Confirmed brown dwarfs are marked in red. Left: The KMOS spectra for the 13 sources identified as brown dwarfs in NGC 2264. For details on the spectral fitting see Sect. 3. arXiv:2108.07633 The slope of the Spitzer/IRAC SED (αIRAC) can be used to identify disc baring sources (Lada et al. 2006). A disc is a strong indication of youth.

Terrestrial Frame from the Combined JASON-2 Orbit (GPS+SLR+DORIS) and GPS Constellation 26th European VLBI Group for Geodesy and Astronomy Working Meeting, 11 – 15 June, 2023, Bad Kötzting, Germany VLBI with GNSS in the L-Band 8.5 GHz Lock-in Amplifier • Frequency range: DC – 8.5 GHz • Directly connected to an antenna - no intermediate frequency, front-end • 2 independent lock-in units with signal generators • Option: measure up to 8 arbitrary frequencies in parallel within the measurement window • A/D conversion: 14 bits, 4 GSa/s • Size: 45×46×14.5 cm 1.8 GHz Lock-in Amplifier • Frequency range: DC – 1.8 GHz • Directly connected to an antenna - no intermediate frequency, front-end • 2 independent lock-in units with signal generators • A/D conversion: 14 bits, 4 GSa/s • Size: 42×45×10 cm VLBI with GNSS is the only way to improve orbits of GNSS satellites in the future Result: combined terrestrial & celestial frame We propose observing GNSS satellites with VLBI operationally in the celestial frame. Basically, the terrestrial frame is fully determined only by the GNSS satellites and the celestial frame is based on the VLBI with AGNs. To combine these two fully independent frames, the only direct solution is to observe AGNs with VLBI in the L-band (L1 and L2 GPS frequencies). All other approaches would introduce local ties and additional effects. This GNSS frequency band is internationally a metrology frequency band outside the interferences with huge LEO constellations of CubeSats operating in the S-band and in the X-band. With the STE-QUEST mission proposal (Svehla et al. 2014), pre-selected (2009-2014) in the ESA Cosmic Vision Programme as well as in GRASP, eGRASP and GENESIS proposals and activities, there is only an indirect link via LEO or a similar orbit between GNSS satellites and AGNs in the celestial frame. This issue is not going to be solved in order to secure orbits of GNSS satellites directly connected with AGNs in the celestial frame. The only way to improve the accuracy of GNSS satellite orbits, and in this way the terrestrial and celestial frame, is to observe GNSS satellites with VLBI relative to the AGNs. LEO orbit is not sufficiently well suited to significantly improving the orbit accuracy of GNSS satellites (gravity, albedo, SRP and thermal re-radiation effects for a very short LEO orbit revolution) nor to be easily observed by all VLBI antennae on the ground. At higher orbit altitudes there are no active satellites placed in the inner Van Allen radiation belts <12000 km that would enable operating such a satellite actively over a longer period of time (e.g. passive LAGEOS satellites or active GPS satellites placed at much higher orbit altitudes). In terms of ICRF frame realization, positions or definitions of AGNs are ”bigger” in the L-band than the X- band, but there are lock-in amplifiers or the existing broadband VLBI receivers (VGOS) that can sample the VLBI signal up to the X-band and that could also cover the L-band simultaneously with the S-band and the X- band. Therefore, the overall cost of such a modification at a VLBI station has been significantly reduced over the years. It is expected that there will be an extension of the celestial frame to higher frequencies such as Q- band and V-band, mainly driven by NASA and ESA for the Delta-DOR technique, but the majority of VLBI stations could only focus on the lower frequency band that could be observed simultaneously in the L-band, S- band and X-band or even up to the Ka-band and used for the realization of reference frames. All GNSS frequencies in the L-band will remain internationally as a metrology frequency band in the future.

Soutenir l’implémentation de la planification de l’espace maritime en Atlantique Nord PARTENAIRES ET AUTORITES NATIONALES Comme SIMNORAT est développé parallèlement à la mise en œuvre de la directive PEM dans les pays, l'implication des autorités compétentes de ces dernières au niveau du comité de pilotage assure des liens et les synergies entre les deux actions. Pour la France, les politiques maritimes sont intégrées dans un ministère, MTES, et la gestion des politiques maritimes est organisée par «bassin maritime». Le Shom (responsable de la sécurité de la navigation et responsable de la description de l'environnement physique marin), le CEREMA (Centre d'études et d'expertise sur les risques, l'environnement, la mobilité et l'aménagement) et l’AFB (Agence française de la biodiversité) sont les principales organisations impliquées dans le processus PEM, avec le MTES et le SGMer (secrétariat général de la mer), bureau du Premier ministre chargé de la coordination des politiques maritimes. A chaque niveau du bassin maritime, plusieurs préfets maritimes et terrestres mettent en œuvre la directive PEM, appuyés par les DIRMs (Direction Inter-régionale de la Mer). En Espagne, deux organisations, déjà impliquées dans le processus de directive cadre sur la stratégie pour le milieu marin, sont déléguées par le ministère de la transition écologique, MITECO, chargé du processus PEM, le CEDEX et l’IEO. L'organisation de la PEM est en cours. Au Portugal, la Direction générale des ressources naturelles, de la sécurité et des services maritimes (DGRM) a délégué l'Université d'Aveiro (UA), qui a participé au projet TPEA. De plus, les régions sont responsables de nombreuses compétences directement liées au processus PEM. Comme il était clairement impossible d'impliquer toutes les régions dans le projet, la CRPM, association de 160 régions maritimes d'Europe, active dans les domaines de la gestion intégrée des zones côtières et de la protection civile, assurera donc le lien avec ce niveau important de gouvernance. SIMNORAT réunit un certain nombre de partenaires - organisations de recherche, autorités de planification maritime et organismes de gestion marine. Ils abordent deux objectifs clés par diverses approches, notamment: recherche documentaire; analyse des tendances futures; développement de scénarios collaboratifs; entretiens avec des parties prenantes; développement d'études de cas; outils d'analyse et de test PEM; mécanismes d'engagement des parties prenantes. Les livrables de SIMNORAT s’adressent aux planificateurs et cherchent à identifier et à partager les meilleures pratiques concernant les aspects techniques (tels que la gestion des données), scientifiques (tels que la gestion écosystémique) et sociaux (tels que les processus d’engagement des parties prenantes) afin de relever les défis de la mise en œuvre de la directive PEM et d’établir une coopération efficace en matière de collaboration transfrontalière de la PEM. Les activités du projet comprennent: - Évaluation initiale concernant la conservation marine et les secteurs maritimes - Analyse du processus PEM - Analyse de la méthodologie de mise en œuvre de la directive PEM avec un accent particulier sur les relations avec Ospar, les interactions terre-mer et la gestion intégrée des côtes, les échelles géographiques - Identification des demandes spatiales et des tendances futures dans les secteurs de la conservation marine et maritime - Prise en charge de l'accès aux données de la PEM et de leur utilisation - Analyse des mécanismes d'engagement des parties prenantes et préparation d'ateliers de parties prenantes (locaux, nationaux, transnationaux) - Études de cas dans le golfe de Gascogne et les eaux marines du nord-ouest des côtes ibériques JANVIER 2017 – JANVIER 2019 Budget: 1.8 Million d’Euro Cofinancé par la EC – DG Affaires maritimes et pêche http://simnorat.eu/ La zone d’intérêt du projet comprend les eaux marines du Portugal, de l’Espagne et de la France de la région d’Os

CONSTRUCTING SPECTRAL ENERGY DISTRIBUTIONS Optical- Cruz+ 2007, NIR- Gonzales+ in prep. TRAPPIST-1 is not as old as the subdwarfs. It most resembles a ﬁeld object with signatures of youth. • Shape of the H band is most similar to ﬁeld dwarfs, but slightly more triangular TRAPPIST-1 is an M7.5 dwarf that hosts seven rocky earth-size planets, three of which are in its habitable zone. Given the abundance of M dwarfs throughout the Galaxy as well as the ease by which rocky planets might be uncovered around low mass stars with future studies like TESS, an inquiry into the uniqueness of the nature of the TRAPPIST-1 system is particularly relevant today. TRAPPIST-1 is classified as a field dwarf with kinematics that suggest it is an “old disk” star. However, the near infrared spectrum of TRAPPIST-1 exhibits a subtle peculiarity that causes it to be classified as an intermediate gravity (INT-G) object using spectral indices. To understand this subtle peculiarity as well as place TRAPPIST-1 in context with other nearby M dwarfs, we have created a distance-calibrated spectral energy distribution (SED). Combining the most recent parallax measurement with optical and infrared spectra and all available photometry, we re-evaluate its bolometric luminosity and effective temperature. We compare the resultant SED to a sample of old, young, and field age objects of similar properties. Using a FIRE echelle spectrum, we also investigate the near-infrared Y, J,H, and K bands to compare observables linked to gravity, atmosphere, metallicity and age effects.
