Modeling the Asymmetric Wind of Massive LBV Binary MWC 314

A. Lobel, J. Groh, K. Torres Dozinel +13

Spectroscopic monitoring with Mercator-HERMES over the past two years reveals that MWC 314 is a massive binary system composed of an early B-type primary LBV star and a less-lumino…

Q-Value and Half-Lives for the Double-Beta-Decay Nuclide 110Pd

D. Fink, J. Barea, D. Beck +17

The 110Pd double-beta decay Q-value was measured with the Penning-trap mass spectrometer ISOLTRAP to be Q = 2017.85(64) keV. This value shifted by 14 keV compared to the literature…

Improving the Efficiency of Approximate Inference for Probabilistic Logical Models by means of Program Specialization

Daan Fierens

We consider the task of performing probabilistic inference with probabilistic logical models. Many algorithms for approximate inference with such models are based on sampling. From…

Relaxation at finite temperature in Fully-Frustrated Ising Models

Jean-Charles Walter, Christophe Chatelain

We consider by means of Monte Carlo simulations the relaxation in the paramagnetic phase of the anti-ferromagnetic Ising model on a triangular lattice and of a fully-frustrated Isi…

Effect of the Generalized Uncertainty Principle on Post-Inflation Preheating

Wissam Chemissany, Saurya Das, Ahmed Farag Ali +1

We examine effects of the Generalized Uncertainty Principle, predicted by various theories of quantum gravity to replace the Heisenberg's uncertainty principle near the Planck scal…

Nesting Probabilistic Inference

Theofrastos Mantadelis, Gerda Janssens

When doing inference in ProbLog, a probabilistic extension of Prolog, we extend SLD resolution with some additional bookkeeping. This additional information is used to compute the…

Sign reversal of the Hall resistance in the mixed-state of La CeCuO and LaCe(CuCo)O thin films

K. Jin, B. X. Wu, B. Y. Zhu +5

The transport properties of LaCeCuO(LCCO) and LaCe(CuCo)O (LCCO:Co) superconducting thin films are investigated. W…

How can a glacial inception be predicted?

Michel Crucifix

The Early Anthropogenic Hypothesis considers that greenhouse gas concentrations should have declined during the Holocene in absence of humankind activity, leading to glacial incept…

Geometry of open strings ending on backreacting D3-branes

Raphael Benichou, John Estes

We investigate open string theory on backreacting D3-branes using a spacetime approach. We study in detail the half-BPS supergravity solutions describing open strings ending on D3-…

Adaptive estimation of linear functionals in functional linear models

Jan Johannes, Rudolf Schenk

We consider the estimation of the value of a linear functional of the slope parameter in functional linear regression, where scalar responses are modeled in dependence of random fu…

Fast core rotation in red-giant stars revealed by gravity-dominated mixed modes

Paul G. Beck, Josefina Montalban, Thomas Kallinger +21

When the core hydrogen is exhausted during stellar evolution, the central region of a star contracts and the outer envelope expands and cools, giving rise to a red giant, in which…

EChO - Exoplanet Characterisation Observatory

G. Tinetti, J. P. Beaulieu, T. Henning +131

A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context…

Asymptotic expansions and fast computation of oscillatory Hilbert transforms

Haiyong Wang, Lun Zhang, Daan Huybrechs

In this paper, we study the asymptotics and fast computation of the one-sided oscillatory Hilbert transforms of the form $$H^{+}(f(t)e^{iωt})(x)=-int_{0}^{\infty}e^{iωt}\frac{f(t)}…

Generalized Monodromy Conjecture in dimension two

András Némethi, Willem Veys

The aim of the article is an extension of the Monodromy Conjecture of Denef and Loeser in dimension two, incorporating zeta functions with differential forms and targeting all mono…

Pulsating hot subdwarfs with MS companions or: EO Ceti is an sdO pulsator!

Roy H. Østensen

About half of the hot subdwarfs are found to have spectra of composite types, indicating a main sequence companion of spectral type F-K, and the pulsators are no exception to this…

The Large N Limit of Toric Chern-Simons Matter Theories and Their Duals

Antonio Amariti, Claudius Klare, Massimo Siani

We compute the large N limit of the localized three dimensional free energy of various field theories with known proposed AdS duals. We show that vector-like theories agree with th…

The fate of Newton's law in brane-world scenarios

Raphael Benichou, John Estes

We consider brane-world scenarios embedded into string theory. We find that the D-brane backreaction induces a large increase in the open string's proper length. Consequently the s…
