Gemini/GMOS Transmission Spectral Survey: Complete Optical Transmission Spectrum of the hot Jupiter WASP-4b | We present the complete optical transmission spectrum of the hot Jupiter
WASP-4b from 440-940 nm at R ~ 400-1500 obtained with the Gemini Multi-Object
Spectrometers (GMOS); this is the first result from a comparative
exoplanetology survey program of close-in gas giants conducted with GMOS.

From Infinite to Finite Programs: Explicit Error Bounds with Applications to Approximate Dynamic Programming | We consider linear programming (LP) problems in infinite dimensional spaces
that are in general computationally intractable. Under suitable assumptions, we
develop an approximation bridge from the infinite-dimensional LP to tractable
finite convex programs in which the performance of the approximation is
quantified e... | 1 | 0 | 1 | 0 | 0 | 0 |
An overview and comparative analysis of Recurrent Neural Networks for Short Term Load Forecasting | The key component in forecasting demand and consumption of resources in a
supply network is an accurate prediction of real-valued time series. Indeed,
both service interruptions and resource waste can be reduced with the
implementation of an effective forecasting system. Significant research has
thus been devoted to ... | 1 | 0 | 0 | 0 | 0 | 0 |
Periods of abelian differentials and dynamics | Given a closed oriented surface S we describe those cohomology classes which
appear as the period characters of abelian differentials for some choice of
complex structure on S consistent with the orientation. The proof is based upon
Ratner's solution of Raghunathan's conjecture.

Existence of regular solutions for a certain type of non-Newtonian Navier-Stokes equations | We are concerned with existence of regular solutions for non-Newtonian fluids
in dimension three. For a certain type of non-Newtonian fluids we prove local
existence of unique regular solutions, provided that the initial data are
sufficiently smooth. Moreover, if the $H^3$-norm of initial data is
sufficiently small, ... | 0 | 0 | 1 | 0 | 0 | 0 |
Multiferroic Quantum Criticality | The zero-temperature limit of a continuous phase transition is marked by a
quantum critical point, which can generate exotic physics that extends to
elevated temperatures. Magnetic quantum criticality is now well known, and has
been explored in systems ranging from heavy fermion metals to quantum Ising
materials. Fer... | 0 | 1 | 0 | 0 | 0 | 0 |
Carbon Nanotube Wools Directly from CO2 By Molten Electrolysis Value Driven Pathways to Carbon Dioxide Greenhouse Gas Mitigation | A climate mitigation comprehensive solution is presented through the first
high yield, low energy synthesis of macroscopic length carbon nanotubes (CNT)
wool from CO2 by molten carbonate electrolysis, suitable for weaving into
carbon composites and textiles. Growing CO2 concentrations, the concurrent
climate change a... | 0 | 1 | 0 | 0 | 0 | 0 |
Rock-Paper-Scissors Random Walks on Temporal Multilayer Networks | We study diffusion on a multilayer network where the contact dynamics between
the nodes is governed by a random process and where the waiting time
distribution differs for edges from different layers. We study the impact on a
random walk of the competition that naturally emerges between the edges of the
different lay... | 1 | 0 | 0 | 0 | 0 | 0 |
Marginally compact fractal trees with semiflexibility | We study marginally compact macromolecular trees that are created by means of
two different fractal generators. In doing so, we assume Gaussian statistics
for the vectors connecting nodes of the trees. Moreover, we introduce bond-bond
correlations that make the trees locally semiflexible. The symmetry of the

Deep Neural Networks for Physics Analysis on low-level whole-detector data at the LHC | There has been considerable recent activity applying deep convolutional
neural nets (CNNs) to data from particle physics experiments. Current
approaches on ATLAS/CMS have largely focussed on a subset of the calorimeter,
and for identifying objects or particular particle types. We explore approaches
that use the entir... | 1 | 0 | 0 | 0 | 0 | 0 |
Time-frequency analysis of ship wave patterns in shallow water: modelling and experiments | A spectrogram of a ship wake is a heat map that visualises the time-dependent
frequency spectrum of surface height measurements taken at a single point as
the ship travels by. Spectrograms are easy to compute and, if properly
interpreted, have the potential to provide crucial information about various

HARE: Supporting efficient uplink multi-hop communications in self-organizing LPWANs | The emergence of low-power wide area networks (LPWANs) as a new agent in the
Internet of Things (IoT) will result in the incorporation into the digital
world of low-automated processes from a wide variety of sectors. The single-hop
conception of typical LPWAN deployments, though simple and robust, overlooks

Tensor tomography in periodic slabs | The X-ray transform on the periodic slab $[0,1]\times\mathbb T^n$, $n\geq0$,
has a non-trivial kernel due to the symmetry of the manifold and presence of
trapped geodesics. For tensor fields gauge freedom increases the kernel
further, and the X-ray transform is not solenoidally injective unless $n=0$. We

Central limit theorem for linear spectral statistics of general separable sample covariance matrices with applications | In this paper, we consider the separable covariance model, which plays an
important role in wireless communications and spatio-temporal statistics and
describes a process where the time correlation does not depend on the spatial
location and the spatial correlation does not depend on time. We established a

Malnormality and join-free subgroups in right-angled Coxeter groups | In this paper, we prove that all finitely generated malnormal subgroups of

particular quasiconvex when the ambient groups are hyperbolic. The key idea is
to prove all infinite proper malnormal subgroups of one-ended right-angled

Mapping the Americanization of English in Space and Time | As global political preeminence gradually shifted from the United Kingdom to

Robot Localisation and 3D Position Estimation Using a Free-Moving Camera and Cascaded Convolutional Neural Networks | Many works in collaborative robotics and human-robot interaction focuses on

robot are calibrated in relation to each other and often the reconfiguration of

Meromorphic Jacobi Forms of Half-Integral Index and Umbral Moonshine Modules | In this work we consider an association of meromorphic Jacobi forms of
half-integral index to the pure D-type cases of umbral moonshine, and solve the
module problem for four of these cases by constructing vertex operator
superalgebras that realise the corresponding meromorphic Jacobi forms as graded
traces. We also ... | 0 | 0 | 1 | 0 | 0 | 0 |
Active Hypothesis Testing: Beyond Chernoff-Stein | An active hypothesis testing problem is formulated. In this problem, the

Data-driven regularization of Wasserstein barycenters with an application to multivariate density registration | We present a framework to simultaneously align and smooth data in the form of

BCS quantum critical phenomena | Theoretically, we recently showed that the scaling relation between the
transition temperature T_c and the superfluid density at zero temperature n_s

is significantly different from the linear scaling described by Homes' law,

Action preserving (weak) topologies on the category of presheaves | Let $\mathcal{C}$ be a finitely complete small category. In this paper, first

functor and the other one, is constructed by an admissible class on
