Electromagnetic structure of nucleon and Roper in soft-wall AdS/QCD

Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt

We present an improved study of the electromagnetic form factors of the nucleon and of the Roper-nucleon transition using an extended version of the effective action of soft-wall A…

PuRe: Robust pupil detection for real-time pervasive eye tracking

Thiago Santini, Wolfgang Fuhl, Enkelejda Kasneci

Real-time, accurate, and robust pupil detection is an essential prerequisite to enable pervasive eye-tracking and its applications -- e.g., gaze-based human computer interaction, h…

QCD Constituent Counting Rules for Neutral Vector Mesons

Stanley J. Brodsky, Richard F. Lebed, Valery E. Lyubovitskij

QCD constituent counting rules define the scaling behavior of exclusive hadronic scattering and electromagnetic scattering amplitudes at high momentum transfer in terms of the tota…

Effective theory of the D = 3 center vortex ensemble

L. E. Oxman, H. Reinhardt

By means of lattice calculations, center vortices have been established as the infrared dominant gauge field configurations of Yang-Mills theory. In this work, we investigate an en…

Functionally-fitted energy-preserving integrators for Poisson systems

Bin Wang, Xinyuan Wu

In this paper, a new class of energy-preserving integrators is proposed and analysed for Poisson systems by using functionally-fitted technology. The integrators exactly preserve e…

Graph partitioning using matrix differential equations

Eleonora Andreotti, Dominik Edelmann, Nicola Guglielmi +1

Given a connected undirected weighted graph, we are concerned with problems related to partitioning the graph. First of all we look for the closest disconnected graph (the minimum…

Growth and evolution of satellites in a Jovian massive disc

Ricardo A Moraes, Wilhelm Kley, Ernesto Vieira Neto

The formation of satellite systems in circum-planetary discs is considered to be similar to the formation of rocky planets in a proto-planetary disc, especially Super-Earths. Thus,…

The evolution of young HII regions

P. D. Klaassen, K. G. Johnston, J. S. Urquhart +6

High-mass stars form in much richer environments than those associated with isolated low-mass stars, and once they reach a certain mass, produce ionised (HII) regions. The formatio…

Physics perspectives with AFTER@LHC (A Fixed Target ExpeRiment at LHC)

L. Massacrier, M. Anselmino, R. Arnaldi +38

AFTER@LHC is an ambitious fixed-target project in order to address open questions in the domain of proton and neutron spins, Quark Gluon Plasma and high- physics, at the highest…

Neutron star solutions with curvature induced scalarization in the extended Gauss-Bonnet scalar-tensor theories

Daniela D. Doneva, Stoytcho S. Yazadjiev

In the present paper we study models of neutron stars in a class of extended scalar-tensor Gauss-Bonnet (ESTGB) theories for which the scalar degree of freedom is exited only in th…

Superhumps linked to X-ray emission. The superoutbursts of SSS J122221.7-311525 and GW Lib

V. V. Neustroev, K. L. Page, E. Kuulkers +6

[Abridged] We present more than 4 years of Swift X-ray observations of the 2013 superoutburst, subsequent decline and quiescence of the WZ Sge-type dwarf nova SSS J122221.7-311525…

On intrinsic quadrics

Anne Fahrner, Juergen Hausen

An intrinsic quadric is a normal projective variety with a Cox ring defined by a single quadratic relation. We provide explicit descriptions of these varieties in the smooth case f…

Quasinormal modes of massive fermions in Kerr spacetime: Long-lived modes and the fine structure

Roman A. Konoplya, Alexander Zhidenko

Quasinormal modes of a massive Dirac field were calculated for various static black hole backgrounds with the help of the WKB formula. These estimations, however, are rough and val…

Signed counts of real simple rational functions

Boulos El Hilany, Johannes Rau

We study the problem of counting real simple rational functions with prescribed ramification data (i.e. a particular class of oriented real Hurwitz numbers of genus ). We in…

Spectral Methods for Coupled Channels with a Mass Gap

H. Weigel, M. Quandt, N. Graham

We develop a method to compute the vacuum polarization energy for coupled scalar fields with different masses scattering off a background potential in one space dimension. As an ex…

Decision-Based Adversarial Attacks: Reliable Attacks Against Black-Box Machine Learning Models

Wieland Brendel, Jonas Rauber, Matthias Bethge

Many machine learning algorithms are vulnerable to almost imperceptible perturbations of their inputs. So far it was unclear how much risk adversarial perturbations carry for the s…

Deciding the existence of a cherry-picking sequence is hard on two trees

Janosch Döcker, Leo van Iersel, Steven Kelk +1

Here we show that deciding whether two rooted binary phylogenetic trees on the same set of taxa permit a cherry-picking sequence, a special type of elimination order on the taxa, i…

Nonclassical states of light with a smooth function

François Damanet, Jonas Kübler, John Martin +1

There is a common understanding in quantum optics that nonclassical states of light are states that do not have a positive semidefinite and sufficiently regular Glauber-Sudarshan $…
