Estimation bounds and sharp oracle inequalities of regularized procedures with Lipschitz loss functions | We obtain estimation error rates and sharp oracle inequalities for
regularization procedures of the form \begin{equation*}
\hat f \in argmin_{f\in
F}\left(\frac{1}{N}\sum_{i=1}^N\ell(f(X_i), Y_i)+\lambda \|f\|\right)

On closed Lie ideals of certain tensor products of $C^*$-algebras | For a simple $C^*$-algebra $A$ and any other $C^*$-algebra $B$, it is proved
that every closed ideal of $A \otimes^{\min} B$ is a product ideal if either
$A$ is exact or $B$ is nuclear. Closed commutator of a closed ideal in a Banach
algebra whose every closed ideal possesses a quasi-central approximate identity

On the Chemistry of the Young Massive Protostellar core NGC 2264 CMM3 | We present the first gas-grain astrochemical model of the NGC 2264 CMM3
protostellar core. The chemical evolution of the core is affected by changing
its physical parameters such as the total density and the amount of
gas-depletion onto grain surfaces as well as the cosmic ray ionisation rate,
$\zeta$. We estimated $... | 0 | 1 | 0 | 0 | 0 | 0 |
Uniform Consistency in Stochastic Block Model with Continuous Community Label | \cite{bickel2009nonparametric} developed a general framework to establish
consistency of community detection in stochastic block model (SBM). In most
applications of this framework, the community label is discrete. For example,
in \citep{bickel2009nonparametric,zhao2012consistency} the degree corrected SBM
is assumed... | 0 | 0 | 0 | 1 | 0 | 0 |
Fine-scale population structure analysis in Armadillidium vulgare (Isopoda: Oniscidea) reveals strong female philopatry | In the last decades, dispersal studies have benefitted from the use of
molecular markers for detecting patterns differing between categories of
individuals, and have highlighted sex-biased dispersal in several species. To
explain this phenomenon, sex-related handicaps such as parental care have been
recently proposed... | 0 | 0 | 0 | 0 | 1 | 0 |
Fast transforms over finite fields of characteristic two | An additive fast Fourier transform over a finite field of characteristic two
efficiently evaluates polynomials at every element of an $\mathbb{F}_2$-linear
subspace of the field. We view these transforms as performing a change of basis
from the monomial basis to the associated Lagrange basis, and consider the

Universality of group embeddability | Working in the framework of Borel reducibility, we study various notions of
embeddability between groups. We prove that the embeddability between countable

isometric embeddability between separable groups with a bounded bi-invariant

Plenoptic Monte Carlo Object Localization for Robot Grasping under Layered Translucency | In order to fully function in human environments, robot perception will need
to account for the uncertainty caused by translucent materials. Translucency
poses several open challenges in the form of transparent objects (e.g.,
drinking glasses), refractive media (e.g., water), and diffuse partial
occlusions (e.g., obj... | 1 | 0 | 0 | 0 | 0 | 0 |
CUR Decompositions, Similarity Matrices, and Subspace Clustering | A general framework for solving the subspace clustering problem using the CUR
decomposition is presented. The CUR decomposition provides a natural way to
construct similarity matrices for data that come from a union of unknown
subspaces $\mathscr{U}=\underset{i=1}{\overset{M}\bigcup}S_i$. The similarity

Approximating Geometric Knapsack via L-packings | We study the two-dimensional geometric knapsack problem (2DK) in which we are
given a set of n axis-aligned rectangular items, each one with an associated
profit, and an axis-aligned square knapsack. The goal is to find a
(non-overlapping) packing of a maximum profit subset of items inside the
knapsack (without rotat... | 1 | 0 | 0 | 0 | 0 | 0 |
Impact and mitigation strategy for future solar flares | It is widely established that extreme space weather events associated with
solar flares are capable of causing widespread technological damage. We develop

phenomena over time. We demonstrate that the economic damage is characterized
by an in... | 0 | 1 | 0 | 0 | 0 | 0 |
Empirical Bayes Matrix Completion | We develop an empirical Bayes (EB) algorithm for the matrix completion
problems. The EB algorithm is motivated from the singular value shrinkage
estimator for matrix means by Efron and Morris (1972). Since the EB algorithm

Excitonic Instability and Pseudogap Formation in Nodal Line Semimetal ZrSiS | Electron correlation effects are studied in ZrSiS using a combination of

of ZrSiS can be described within a two-dimensional lattice model of two nested
square lattices. High degree of electron-hole symmetry characteristic for ZrSiS

The Riemannian Geometry of Deep Generative Models | Deep generative models learn a mapping from a low dimensional latent space to

Portable, high-performance containers for HPC | Building and deploying software on high-end computing systems is a

while resolving complicated software-stack dependencies. Containers are a type
of lightweight virt... | 1 | 0 | 0 | 0 | 0 | 0 |
Learning a Deep Convolution Network with Turing Test Adversaries for Microscopy Image Super Resolution | Adversarially trained deep neural networks have significantly improved

Quantum dynamics of a hydrogen-like atom in a time-dependent box: non-adiabatic regime | We consider a hydrogen atom confined in time-dependent trap created by a

the behavior of atomic electron under the (non-adiabatic) dynamical confinement
caused by the rapidly moving wall of the box. The expectation values of the

Richardson's solutions in the real- and complex-energy spectrum | The constant pairing Hamiltonian holds exact solutions worked out by

Complexity Results for MCMC derived from Quantitative Bounds | This paper considers how to obtain MCMC quantitative convergence bounds which

Symmetries and regularity for holomorphic maps between balls | Let $f:{\mathbb B}^n \to {\mathbb B}^N$ be a holomorphic map. We study

Aut}({\mathbb B}^N)$. When $f$ is proper, we show both these groups are Lie

On the treatment of $\ell$-changing proton-hydrogen Rydberg atom collisions | Energy-conserving, angular momentum-changing collisions between protons and
