A wide field-of-view crossed Dragone optical system using the anamorphic aspherical surfaces | A side-fed crossed Dragone telescope provides a wide field-of-view. This type
of a telescope is commonly employed in the measurement of cosmic microwave
background (CMB) polarization, which requires an image-space telecentric
telescope with a large focal plane over broadband coverage. We report the

Searching for Biophysically Realistic Parameters for Dynamic Neuron Models by Genetic Algorithms from Calcium Imaging Recording | Individual Neurons in the nervous systems exploit various dynamics. To
capture these dynamics for single neurons, we tune the parameters of an
electrophysiological model of nerve cells, to fit experimental data obtained by
calcium imaging. A search for the biophysical parameters of this model is
performed by means of... | 1 | 0 | 0 | 0 | 0 | 0 |
Matrix elements of irreducible representations of $\mathrm{SU}(n+1)\times\mathrm{SU}(n+1)$ and multivariable matrix-valued orthogonal polynomials | In Part 1 we study the spherical functions on compact symmetric pairs of
arbitrary rank under a suitable multiplicity freeness assumption and additional
conditions on the branching rules. The spherical functions are taking values in
the spaces of linear operators of a finite dimensional representation of the
subgroup... | 0 | 0 | 1 | 0 | 0 | 0 |
On the variance of internode distance under the multispecies coalescent | We consider the problem of estimating species trees from unrooted gene tree
topologies in the presence of incomplete lineage sorting, a common phenomenon
that creates gene tree heterogeneity in multilocus datasets. One popular class
of reconstruction methods in this setting is based on internode distances, i.e.

DOPING: Generative Data Augmentation for Unsupervised Anomaly Detection with GAN | Recently, the introduction of the generative adversarial network (GAN) and
its variants has enabled the generation of realistic synthetic samples, which
has been used for enlarging training sets. Previous work primarily focused on
data augmentation for semi-supervised and supervised tasks. In this paper, we

Online Human Gesture Recognition using Recurrent Neural Networks and Wearable Sensors | Gestures are a natural communication modality for humans. The ability to
interpret gestures is fundamental for robots aiming to naturally interact with
humans. Wearable sensors are promising to monitor human activity, in particular
the usage of triaxial accelerometers for gesture recognition have been
explored. Despi... | 1 | 0 | 0 | 0 | 0 | 0 |
Conditional Variance Penalties and Domain Shift Robustness | When training a deep network for image classification, one can broadly
distinguish between two types of latent features of images that will drive the
classification. Following the notation of Gong et al. (2016), we can divide
latent features into (i) "core" features $X^\text{core}$ whose distribution

The First Optical Spectra of Wolf Rayet Stars in M101 Revealed with Gemini/GMOS | Deep narrow-band HST imaging of the iconic spiral galaxy M101 has revealed
over a thousand new Wolf Rayet (WR) candidates. We report spectrographic
confirmation of 10 HeII emission line sources hosting 15 WR stars. We find WR
stars present at both sub- and super-solar metalicities with WC stars favouring

Machine Learning Topological Invariants with Neural Networks | In this Letter we supervisedly train neural networks to distinguish different

the neural network can predict their topological winding numbers with nearly
100% accurac... | 1 | 1 | 0 | 0 | 0 | 0 |
Topics and Label Propagation: Best of Both Worlds for Weakly Supervised Text Classification | We propose a Label Propagation based algorithm for weakly supervised text
classification. We construct a graph where each document is represented by a
node and edge weights represent similarities among the documents. Additionally,
we discover underlying topics using Latent Dirichlet Allocation (LDA) and
enrich the do... | 1 | 0 | 0 | 0 | 0 | 0 |
Parallel Markov Chain Monte Carlo for the Indian Buffet Process | Indian Buffet Process based models are an elegant way for discovering
underlying features within a data set, but inference in such models can be

relies on an uncollapsed representation, which leads to poor mixing, or on a
collapsed representati... | 0 | 0 | 0 | 1 | 0 | 0 |
The Robot Routing Problem for Collecting Aggregate Stochastic Rewards | We propose a new model for formalizing reward collection problems on graphs
with dynamically generated rewards which may appear and disappear based on a

are stochastic processes generating potential rewards over discrete time. The
rewards... | 1 | 0 | 1 | 0 | 0 | 0 |
Estimating occupation time functionals | We study the estimation of integral type functionals $\int_{0}^{t}f(X_{r})dr$

Bootstrapping a Lexicon for Emotional Arousal in Software Engineering | Emotional arousal increases activation and performance but may also lead to

Early Solar System irradiation quantified by linked vanadium and beryllium isotope variations in meteorites | X-ray emission in young stellar objects (YSOs) is orders of magnitude more

Two classes of nonlocal Evolution Equations related by a shared Traveling Wave Problem | We consider reaction-diffusion equations and Korteweg-de Vries-Burgers (KdVB)
equations, i.e. scalar conservation laws with diffusive-dispersive
regularization. We review the existence of traveling wave solutions for these
two classes of evolution equations. For classical equations the traveling wave

Analyzing IO Amplification in Linux File Systems | We present the first systematic analysis of read, write, and space

Feature analysis of multidisciplinary scientific collaboration patterns based on PNAS | The features of collaboration patterns are often considered to be different

Inflationary magneto-(non)genesis, increasing kinetic couplings, and the strong coupling problem | We study the generation of magnetic fields during inflation making use of a

Assessing the reliability polynomial based on percolation theory | In this paper, we study the robustness of network topologies. We use the

Interval Exchange Transformations and Low-Discrepancy | In [Mas82] and [Vee78] it was proved independently that almost every interval
exchange transformation is uniquely ergodic. The Birkhoff ergodic theorem
implies that these maps mainly have uniformly distributed orbits. This raises
the question under which conditions the orbits yield low-discrepancy sequences.
