An objective classification of Saturn cloud features from Cassini ISS images | A clustering algorithm is applied to Cassini Imaging Science Subsystem
continuum and methane band images of Saturns northern hemisphere to objectively
classify regional albedo features and aid in their dynamical interpretation.
The procedure is based on a technique applied previously to visible-infrared
images of Ear... | 0 | 1 | 0 | 0 | 0 | 0 |
The Peridynamic Stress Tensors and the Non-local to Local Passage | We re-examine the notion of stress in peridynamics. Based on the idea of
traction we define two new peridynamic stress tensors $\mathbf{P}^{\mathbf{y}}$
and $\mathbf{P}$ which stand, respectively, for analogues of the Cauchy and 1st
Piola-Kirchhoff stress tensors from classical elasticity. We show that the
tensor $\m... | 0 | 1 | 0 | 0 | 0 | 0 |
Identification of Unmodeled Objects from Symbolic Descriptions | Successful human-robot cooperation hinges on each agent's ability to process
and exchange information about the shared environment and the task at hand.
Human communication is primarily based on symbolic abstractions of object
properties, rather than precise quantitative measures. A comprehensive robotic
framework th... | 1 | 0 | 0 | 1 | 0 | 0 |
Balanced News Using Constrained Bandit-based Personalization | We present a prototype for a news search engine that presents balanced
viewpoints across liberal and conservative articles with the goal of
de-polarizing content and allowing users to escape their filter bubble. The
balancing is done according to flexible user-defined constraints, and leverages

Intuitionistic Layered Graph Logic: Semantics and Proof Theory | Models of complex systems are widely used in the physical and social
sciences, and the concept of layering, typically building upon graph-theoretic
structure, is a common feature. We describe an intuitionistic substructural
logic called ILGL that gives an account of layering. The logic is a bunched
system, combining ... | 1 | 0 | 0 | 0 | 0 | 0 |
Learning Efficient Image Representation for Person Re-Identification | Color names based image representation is successfully used in person
re-identification, due to the advantages of being compact, intuitively
understandable as well as being robust to photometric variance. However, there
exists the diversity between underlying distribution of color names' RGB values
and that of image ... | 1 | 0 | 0 | 0 | 0 | 0 |
Exciting Nucleons in Compton Scattering and Hydrogen-Like Atoms | This PhD thesis is devoted to the low-energy structure of the nucleon (proton
and neutron) as seen through electromagnetic probes, e.g., electron and Compton
scattering. The research presented here is based primarily on dispersion theory
and chiral effective-field theory. The main motivation is the recent proton

Multiple universalities in order-disorder magnetic phase transitions | Phase transitions in isotropic quantum antiferromagnets are associated with
the condensation of bosonic triplet excitations. In three dimensional quantum
antiferromagnets, such as TlCuCl$_3$, condensation can be either pressure or
magnetic field induced. The corresponding magnetic order obeys universal
scaling with t... | 0 | 1 | 0 | 0 | 0 | 0 |
Exact Inference of Causal Relations in Dynamical Systems | From philosophers of ancient times to modern economists, biologists and other
researchers are engaged in revealing causal relations. The most challenging
problem is inferring the type of the causal relationship: whether it is uni- or
bi-directional or only apparent - implied by a hidden common cause only. Modern
tech... | 0 | 0 | 0 | 0 | 1 | 0 |
Privacy-Preserving Deep Inference for Rich User Data on The Cloud | Deep neural networks are increasingly being used in a variety of machine
learning applications applied to rich user data on the cloud. However, this
approach introduces a number of privacy and efficiency challenges, as the cloud
operator can perform secondary inferences on the available data. Recently,
advances in ed... | 1 | 0 | 0 | 0 | 0 | 0 |
Gradient Method With Inexact Oracle for Composite Non-Convex Optimization | In this paper, we develop new first-order method for composite non-convex
minimization problems with simple constraints and inexact oracle. The objective
function is given as a sum of "`hard"', possibly non-convex part, and
"`simple"' convex part. Informally speaking, oracle inexactness means that, for

Kernel Implicit Variational Inference | Recent progress in variational inference has paid much attention to the
flexibility of variational posteriors. One promising direction is to use
implicit distributions, i.e., distributions without tractable densities as the
variational posterior. However, existing methods on implicit posteriors still
face challenges ... | 1 | 0 | 0 | 1 | 0 | 0 |
The Ringel dual of the Auslander-Dlab-Ringel algebra | The ADR algebra $R_A$ of a finite-dimensional algebra $A$ is a
quasihereditary algebra. In this paper we study the Ringel dual
$\mathcal{R}(R_A)$ of $R_A$. We prove that $\mathcal{R}(R_A)$ can be identified
with $(R_{A^{op}})^{op}$, under certain 'minimal' regularity conditions for
$A$. We also give necessary and suf... | 0 | 0 | 1 | 0 | 0 | 0 |
The socle filtrations of principal series representations of $SL(3,\mathbb{R})$ and $Sp(2,\mathbb{R})$ | We study the structure of the $(\mathfrak{g},K)$-modules of the principal
series representations of $SL(3,\mathbb{R})$ and $Sp(2,\mathbb{R})$ induced
from minimal parabolic subgroups, in the case when the infinitesimal character
is nonsingular. The composition factors of these modules are known by

Improving the phase response of an atom interferometer by means of temporal pulse shaping | We study theoretically and experimentally the influence of temporally shaping
the light pulses in an atom interferometer, with a focus on the phase response
of the interferometer. We show that smooth light pulse shapes allow rejecting
high frequency phase fluctuations (above the Rabi frequency) and thus relax the

Helium-like and Lithium-like ions: Ground state energy | It is shown that the non-relativistic ground state energy of helium-like and

Improvement of training set structure in fusion data cleaning using Time-Domain Global Similarity method | Traditional data cleaning identifies dirty data by classifying original data
sequences, which is a class$-$imbalanced problem since the proportion of

Thermoregulation in mice, rats and humans: An insight into the evolution of human hairlessness | The thermoregulation system in animals removes body heat in hot temperatures
and retains body heat in cold temperatures. The better the animal removes heat,
the worse the animal retains heat and visa versa. It is the balance between
these two conflicting goals that determines the mammal's size, heart rate and

Koszul A-infinity algebras and free loop space homology | We introduce a notion of Koszul A-infinity algebra that generalizes Priddy's
notion of a Koszul algebra and we use it to construct small A-infinity algebra
models for Hochschild cochains. As an application, this yields new techniques
for computing free loop space homology algebras of manifolds that are either
