A study of the dual problem of the one-dimensional L-infinity optimal transport problem with applications | The Monge-Kantorovich problem for the infinite Wasserstein distance presents
several peculiarities. Among them the lack of convexity and then of a direct
duality. We study in dimension 1 the dual problem introduced by Barron, Bocea
and Jensen. We construct a couple of Kantorovich potentials which is "as less

Strong coupling Bose polarons in a BEC | We use a non-perturbative renormalization group approach to develop a unified
picture of the Bose polaron problem, where a mobile impurity is strongly
interacting with a surrounding Bose-Einstein condensate (BEC). A detailed
theoretical analysis of the phase diagram is presented and the
polaron-to-molecule transition... | 0 | 1 | 0 | 0 | 0 | 0 |
Triangle packing in (sparse) tournaments: approximation and kernelization | Given a tournament T and a positive integer k, the C_3-Pakcing-T problem asks
if there exists a least k (vertex-)disjoint directed 3-cycles in T. This is the
dual problem in tournaments of the classical minimal feedback vertex set
problem. Surprisingly C_3-Pakcing-T did not receive a lot of attention in the

Asymptotics of Chebyshev Polynomials, II. DCT Subsets of $\mathbb{R}$ | We prove Szegő-Widom asymptotics for the Chebyshev polynomials of a

Tracking Urban Human Activity from Mobile Phone Calling Patterns | Timings of human activities are marked by circadian clocks which in turn are
entrained to different environmental signals. In an urban environment the
presence of artificial lighting and various social cues tend to disrupt the
natural entrainment with the sunlight. However, it is not completely understood
to what ext... | 0 | 1 | 0 | 0 | 0 | 0 |
Efficient conversion from rotating matrix to rotation axis and angle by extending Rodrigues' formula | In computational 3D geometric problems involving rotations, it is often that
people have to convert back and forth between a rotational matrix and a
rotation described by an axis and a corresponding angle. For this purpose,
Rodrigues' rotation formula is a very popular expression to use because of its
simplicity and ... | 1 | 0 | 0 | 0 | 0 | 0 |
Statistical methods for characterizing transfusion-related changes in regional oxygenation using Near-infrared spectroscopy (NIRS) in preterm infants | Near infrared spectroscopy (NIRS) is an imaging-based diagnostic tool that

technology to help detect relative tissue ischemia that could lead to
significant morbid... | 0 | 0 | 0 | 1 | 0 | 0 |
To understand deep learning we need to understand kernel learning | Generalization performance of classifiers in deep learning has recently
become a subject of intense study. Deep models, typically over-parametrized,
tend to fit the training data exactly. Despite this "overfitting", they perform
well on test data, a phenomenon not yet fully understood.
The first point of our paper is... | 0 | 0 | 0 | 1 | 0 | 0 |
Atomic Data Revisions for Transitions Relevant to Observations of Interstellar, Circumgalactic, and Intergalactic Matter | Measurements of element abundances in galaxies from astrophysical

wavelengths longward of 911.753 {\AA}... | 0 | 1 | 0 | 0 | 0 | 0 |
Using Nonlinear Normal Modes for Execution of Efficient Cyclic Motions in Soft Robots | With the aim of getting closer to the performance of the animal

with increased efficiency,... | 1 | 0 | 0 | 0 | 0 | 0 |
Efficient Deep Learning on Multi-Source Private Data | Machine learning models benefit from large and diverse datasets. Using such

secure an... | 0 | 0 | 0 | 1 | 0 | 0 |
Analytical solution of the integral equation for partial wave Coulomb t-matrices at excited-state energy | Starting from the integral representation of the three-dimensional Coulomb

Equilateral $p$-gons in $\mathbb R^d$ and deformed spheres and mod $p$ Fadell-Husseini index | We introduce the concept of $r$-equilateral $m$-gons. We prove the existence
of $r$-equilateral $p$-gons in $\mathbb R^d$ if $r<d$ and the existence of
equilateral $p$-gons in the image of continuous injective maps $f:S^d\to
\mathbb R^{d+1}$. Our ideas are based mainly in the paper of Y. Soibelman

Jónsson posets | According to Kearnes and Oman (2013), an ordered set $P$ is \emph{Jónsson}
if it is infinite and the cardinality of every proper initial segment of $P$ is
strictly less than the cardinaliy of $P$. We examine the structure of Jónsson
posets.

Hypotheses testing on infinite random graphs | Drawing on some recent results that provide the formalism necessary to

Octupolar Tensors for Liquid Crystals | A third-order three-dimensional symmetric traceless tensor, called the

Efficient boundary corrected Strang splitting | Strang splitting is a well established tool for the numerical integration of

can be remedied... | 0 | 1 | 0 | 0 | 0 | 0 |
SOS-convex Semi-algebraic Programs and its Applications to Robust Optimization: A Tractable Class of Nonsmooth Convex Optimization | In this paper, we introduce a new class of nonsmooth convex functions called

An Uncertainty Principle for Estimates of Floquet Multipliers | We derive a Cramér-Rao lower bound for the variance of Floquet multiplier

Shielding Google's language toxicity model against adversarial attacks | Lack of moderation in online communities enables participants to incur in

Diagrammatic Monte-Carlo for weak-coupling expansion of non-Abelian lattice field theories: large-N U(N)xU(N) principal chiral model | We develop numerical tools for Diagrammatic Monte-Carlo simulations of

Training Shallow and Thin Networks for Acceleration via Knowledge Distillation with Conditional Adversarial Networks | There is an increasing interest on accelerating neural networks for real-time
