Interplay between pulsation, mass loss, and third dredge-up: More about Miras with and without technetium
Stefan Uttenthaler, Iain McDonald, Klaus Bernhard +2
We follow-up on a previous finding that AGB Mira variables containing the 3DUP indicator technetium (Tc) in their atmosphere form a different sequence of K-[22] colour as a functio…
Exploring the Challenges towards Lifelong Fact Learning
Mohamed Elhoseiny, Francesca Babiloni, Rahaf Aljundi +3
So far life-long learning (LLL) has been studied in relatively small-scale and relatively artificial setups. Here, we introduce a new large-scale alternative. What makes the propos…
Solar Magnetic Flux Rope Eruption Simulated by a Data-Driven Magnetohydrodynamic Model
Yang Guo, Chun Xia, Rony Keppens +2
The combination of magnetohydrodynamic (MHD) simulation and multi-wavelength observations is an effective way to study mechanisms of magnetic flux rope eruption. We develop a data-…
Quasi-periodic pulsations in a solar flare with an unusual phase shift
Elena G. Kupriyanova, Larisa K. Kashapova, Tom Van Doorsselaere +3
Two kinds of processes could occur during the flare decay phase: processes of energy release or processes of energy relaxation. Quasi-periodic pulsations (QPPs) of the broadband em…
Prepaid parameter estimation without likelihoods
Merijn Mestdagh, Stijn Verdonck, Kristof Meers +2
In various fields, statistical models of interest are analytically intractable. As a result, statistical inference is greatly hampered by computational constraints. However, given…
Top-quark effects in diphoton production through gluon fusion at NLO in QCD
Fabio Maltoni, Manoj K. Mandal, Xiaoran Zhao
At hadron colliders, the leading production mechanism for a pair of photons is from quark-anti-quark annihilation at the tree level. However, due to large gluon-gluon luminosity, t…
Using Nab to determine correlations in unpolarized neutron decay
L. J. Broussard, S. Baeßler, T. L. Bailey +28
The Nab experiment will measure the ratio of the weak axial-vector and vector coupling constants with precision and search for a Fierz term $b_…
On product affine hyperspheres in
Xiuxiu Cheng, Zejun Hu, Marilena Moruz +1
In this paper, we study locally strongly convex affine hyperspheres in the unimodular affine space which, as Riemannian manifolds, are locally isometric to the R…
decay study of the Mn - Fe - Co - Ni chain
M. Stryjczyk, Y. Tsunoda, I. G. Darby +19
Background: Shell evolution can impact the structure of the nuclei and lead to effects such as shape coexistence. The nuclei around Ni represent an excellent study case, how…
No unique solution to the seismological problem of standing kink MHD waves
Inigo Arregui, Marcel Goossens
The aim of this paper is to point out that the classic seismological problem using observations and theoretical expressions for the periods and damping times of transverse standing…
High-resolution spectroscopy of Boyajian's star during optical dimming events
M. J. Martínez González, C. González-Fernández, A. Asensio Ramos +13
Boyajian's star is an apparently normal main sequence F-type star with a very unusual light curve. The dipping activity of the star, discovered during the Kepler mission, presents…
Quadratic Soliton Combs in Doubly-Resonant Second-Harmonic Generation
T. Hansson, P. Parra-Rivas, M. Bernard +3
We report a theoretical investigation of quadratic frequency combs in a dispersive second-harmonic generation cavity system. We identify different dynamical regimes and demonstrate…
Investigating the properties of stripped-envelope supernovae, what are the implications for their progenitors?
S. J. Prentice, C. Ashall, P. A. James +41
We present observations and analysis of 18 stripped-envelope supernovae observed during 2013 -- 2018. This sample consists of 5 H/He-rich SNe, 6 H-poor/He-rich SNe, 3 narrow lined…
A Low-Rank and Joint-Sparse Model for Ultrasound Signal Reconstruction
Miaomiao Zhang, Ivan Markovsky, Colas Schretter +1
With the introduction of very dense sensor arrays in ultrasound (US) imaging, data transfer rate and data storage became a bottleneck in ultrasound system design. To reduce the amo…
Aerial navigation in obstructed environments with embedded nonlinear model predictive control
Elias Small, Pantelis Sopasakis, Emil Fresk +2
We propose a methodology for autonomous aerial navigation and obstacle avoidance of micro aerial vehicles (MAV) using nonlinear model predictive control (NMPC) and we demonstrate i…
Euclidean axion wormholes have multiple negative modes
Thomas Hertog, Brecht Truijen, Thomas Van Riet
We show that Euclidean axion wormholes in theories of gravity coupled to a single axion have several independent inhomogeneous perturbations that lower the Euclidean action. Our an…
White dwarfs in the building blocks of the Galactic spheroid
Pim van Oirschot, Gijs Nelemans, Else Starkenburg +3
The galactic halo likely grew over time in part by assembling smaller galaxies, the so-called building blocks. We investigate if the properties of these building blocks are reflect…
Semi-analytic modelling of the europium production by neutron star mergers in the halo of the Milky Way
Pim van Oirschot, Gijs Nelemans, Onno Pols +1
Neutron star mergers (NSM) are likely to be the main production sites for the rapid (r-) neutron capture process elements. We study the r-process enrichment of the stellar halo of…
The asymptotic speed of reaction fronts in active reaction-diffusion systems
Thibaut Demaerel, Christian Maes
We study various combinations of active diffusion with branching, as an extension of standard reaction-diffusion processes. We concentrate on the selection of the asymptotic wavefr…
What is the No-Boundary Wave Function of the Universe?
Jonathan J. Halliwell, James B. Hartle, Thomas Hertog
We specify the semiclassical no-boundary wave function of the universe without relying on a functional integral of any kind. The wave function is given as a sum of specific saddle…
Multiple Hermite polynomials and simultaneous Gaussian quadrature
Walter Van Assche, Anton Vuerinckx
Multiple Hermite polynomials are an extension of the classical Hermite polynomials for which orthogonality conditions are imposed with respect to normal (Gaussian) weights $w…
Mass Deformations of the ABJM Theory: The Holographic Free Energy
Nikolay Bobev, Vincent S. Min, Krzysztof Pilch +1
We find a class of new supersymmetric Euclidean solutions in four-dimensional maximal gauged supergravity. The holographic dual description of these backgrounds is given by a mass-…
Bigalois extensions and the graph isomorphism game
Michael Brannan, Alexandru Chirvasitu, Kari Eifler +4
We study the graph isomorphism game that arises in quantum information theory from the perspective of bigalois extensions of compact quantum groups. We show that every algebraic qu…
Probing Black Hole Microstate Evolution with Networks and Random Walks
Anthony M. Charles, Daniel R. Mayerson
We model black hole microstates and quantum tunneling transitions between them with networks and simulate their time evolution using well-established tools in network theory. In pa…
