Wheeler's concept of "law without law," as a "structure without law," and a new
philosophical viewpoint, that of structural nnnrealism, and considers how this
concept and this viewpoint work in quantum theory in general and quantum

Robotics CTF (RCTF), a playground for robot hacking | Robots state of insecurity is onstage. There is an emerging concern about
major robot vulnerabilities and their adverse consequences. However, there is
still a considerable gap between robotics and cybersecurity domains. For the
purpose of filling that gap, the present technical report presents the Robotics
CTF (RCTF... | 1 | 0 | 0 | 0 | 0 | 0 |
Effects of transmutation elements in tungsten as a plasma facing material | Tungsten (W) is widely considered as the most promising plasma facing
material, which is used in nuclear fusion devices. During the operation of the
nuclear fusion devices, transmutation elements, such as Re, Os, and Ta, are
generated in W due to the transmutation reaction under fusion neutron
irradiation. In this pa... | 0 | 1 | 0 | 0 | 0 | 0 |
A playful note on spanning and surplus edges | Consider a (not necessarily near-critical) random graph running in continuous
time. A recent breadth-first-walk construction is extended in order to account
for the surplus edge data in addition to the spanning edge data. Two different
graph representations of the multiplicative coalescent, with different
advantages ... | 0 | 0 | 1 | 0 | 0 | 0 |
Logo Synthesis and Manipulation with Clustered Generative Adversarial Networks | Designing a logo for a new brand is a lengthy and tedious back-and-forth
process between a designer and a client. In this paper we explore to what
extent machine learning can solve the creative task of the designer. For this,
we build a dataset -- LLD -- of 600k+ logos crawled from the world wide web.

Multi-view Supervision for Single-view Reconstruction via Differentiable Ray Consistency | We study the notion of consistency between a 3D shape and a 2D observation
and propose a differentiable formulation which allows computing gradients of
the 3D shape given an observation from an arbitrary view. We do so by
reformulating view consistency using a differentiable ray consistency (DRC)
term. We show that t... | 1 | 0 | 0 | 0 | 0 | 0 |
Efficient Rank Minimization via Solving Non-convexPenalties by Iterative Shrinkage-Thresholding Algorithm | Rank minimization (RM) is a wildly investigated task of finding solutions by
exploiting low-rank structure of parameter matrices. Recently, solving RM
problem by leveraging non-convex relaxations has received significant
attention. It has been demonstrated by some theoretical and experimental work
that non-convex rel... | 0 | 0 | 0 | 1 | 0 | 0 |
Almost Buchsbaumness of some rings arising from complexes with isolated singularities | We study properties of the Stanley-Reisner rings of simplicial complexes with
isolated singularities modulo two generic linear forms. Miller, Novik, and
Swartz proved that if a complex has homologically isolated singularities, then
its Stanley-Reisner ring modulo one generic linear form is Buchsbaum. Here we

Dynamically controlled plasmonic nano-antenna phased array utilizing vanadium dioxide | We propose and analyze theoretically an approach for realizing a tunable
optical phased-array antenna utilizing the properties of VO2 for electronic
beam steering applications in the near-IR spectral range. The device is based
on a 1D array of slot nano-antennas engraved in a thin Au film grown over VO2
layer. The tu... | 0 | 1 | 0 | 0 | 0 | 0 |
Comparing deep neural networks against humans: object recognition when the signal gets weaker | Human visual object recognition is typically rapid and seemingly effortless,
as well as largely independent of viewpoint and object orientation. Until very
recently, animate visual systems were the only ones capable of this remarkable
computational feat. This has changed with the rise of a class of computer
vision al... | 1 | 0 | 0 | 1 | 0 | 0 |
Quantum critical response: from conformal perturbation theory to holography | We discuss dynamical response functions near quantum critical points,
allowing for both a finite temperature and detuning by a relevant operator.
When the quantum critical point is described by a conformal field theory (CFT),
conformal perturbation theory and the operator product expansion can be used to
fix the firs... | 0 | 1 | 0 | 0 | 0 | 0 |
Testing High-dimensional Covariance Matrices under the Elliptical Distribution and Beyond | We study testing high-dimensional covariance matrices under a generalized
elliptical model. The model accommodates several stylized facts of real data
including heteroskedasticity, heavy-tailedness, asymmetry, etc. We consider the
high-dimensional setting where the dimension $p$ and the sample size $n$ grow

Work Analysis with Resource-Aware Session Types | While there exist several successful techniques for supporting programmers in
deriving static resource bounds for sequential code, analyzing the resource
usage of message-passing concurrent processes poses additional challenges. To
meet these challenges, this article presents an analysis for statically

Seven dimensional cohomogeneity one manifolds with nonnegative curvature | We show that a certain family of cohomogeneity one manifolds does not admit
an invariant metric of nonnegative sectional curvature, unless it admits one
with positive curvature. As a consequence, the classification of nonnegatively
curved cohomogeneity one manifolds in dimension 7 is reduced to only one
further famil... | 0 | 0 | 1 | 0 | 0 | 0 |
Optimal Rates of Sketched-regularized Algorithms for Least-Squares Regression over Hilbert Spaces | We investigate regularized algorithms combining with projection for
least-squares regression problem over a Hilbert space, covering nonparametric
regression over a reproducing kernel Hilbert space. We prove convergence

The scaling properties and the multiple derivative of Legendre polynomials | In this paper, we study the scaling properties of Legendre polynomials Pn(x).
We show that Pn(ax), where a is a constant, can be expanded as a sum of either
Legendre polynomials Pn(x) or their multiple derivatives dkPn(x)/dxk, and we
derive a general expression for the expansion coefficients. In addition, we

Knockoffs for the mass: new feature importance statistics with false discovery guarantees | An important problem in machine learning and statistics is to identify
features that causally affect the outcome. This is often impossible to do from
purely observational data, and a natural relaxation is to identify features
that are correlated with the outcome even conditioned on all other observed
features. For ex... | 0 | 0 | 0 | 1 | 0 | 0 |
Phase boundaries in alternating field quantum XY model with Dzyaloshinskii-Moriya interaction: Sustainable entanglement in dynamics | We report all phases and corresponding critical lines of the quantum
anisotropic transverse XY model with Dzyaloshinskii-Moriya (DM) interaction
along with uniform and alternating transverse magnetic fields (ATXY) by using
appropriately chosen order parameters. We prove that when DM interaction is
weaker than the ani... | 0 | 1 | 0 | 0 | 0 | 0 |
Descent of equivalences and character bijections | Categorical equivalences between block algebras of finite groups - such as
Morita and derived equivalences - are well-known to induce character bijections
which commute with the Galois groups of field extensions. This is the
motivation for attempting to realise known Morita and derived equivalences over
non splitting... | 0 | 0 | 1 | 0 | 0 | 0 |
A function field analogue of the Rasmussen-Tamagawa conjecture: The Drinfeld module case | In the arithmetic of function fields, Drinfeld modules play the role that
elliptic curves play in the arithmetic of number fields. The aim of this paper
is to study a non-existence problem of Drinfeld modules with constrains on
torsion points at places with large degree. This is motivated by a conjecture

Malware Detection Using Dynamic Birthmarks | In this paper, we explore the effectiveness of dynamic analysis techniques
for identifying malware, using Hidden Markov Models (HMMs) and Profile Hidden

that d... | 1 | 0 | 0 | 1 | 0 | 0 |
Semi-analytical approximations to statistical moments of sigmoid and softmax mappings of normal variables | This note is concerned with accurate and computationally efficient
approximations of moments of Gaussian random variables passed through sigmoid
