Thermal performance of GaInSb quantum well lasers for silicon photonics applications
Christopher R. Fitch, Graham W. Read, Igor P. Marko +5
A key component for the realization of silicon-photonics are integrated lasers operating in the important communications band near 1.55 m. One approach is through the use of GaS…
Weak gravity on a CDM background
Radouane Gannouji, Leandros Perivolaropoulos, David Polarski +1
We consider Horndeski modified gravity models obeying stability, velocity of gravitational waves equals and quasistatic approximation (QSA) on subhorizon scales. We assum…
Observation of a sudden cessation of a very-high-energy gamma-ray flare in PKS 1510-089 with H.E.S.S. and MAGIC in May 2016
H. E. S. S. Collaboration, H. Abdalla, R. Adam +430
The flat spectrum radio quasar (FSRQ) PKS 1510-089 is known for its complex multiwavelength behavior, and is one of only a few FSRQs detected at very high energy (VHE, GeV…
Role of normal stress in the creep dynamics and failure of a biopolymer gel
Angelo Pommella, Luca Cipelletti, Laurence Ramos
We investigate the delayed rupture of biopolymer gels under a constant shear load by simultaneous dynamic light scattering and rheology measurements. We unveil the crucial role of…
39 Hints to Facilitate the Use of Semantics for Data on Agriculture and Nutrition
Caterina Caracciolo, Sophie Aubin, Clement Jonquet +7
In this paper, we report on the outputs and adoption of the Agrisemantics Working Group of the Research Data Alliance (RDA), consisting of a set of recommendations to facilitate th…
Micromechanical description of the compaction of soft pentagon assemblies
Manuel Cárdenas-Barrantes, David Cantor, Jonathan Barés +2
We analyze the isotropic compaction of assemblies composed of soft pentagons interacting through classical Coulomb friction via numerical simulations. The effect of the initial par…
Magnetic field and chromospheric activity evolution of HD75332: a rapid magnetic cycle in an F star without a hot Jupiter
E. L. Brown, S. C. Marsden, M. W. Mengel +10
Studying cool star magnetic activity gives an important insight into the stellar dynamo and its relationship with stellar properties, as well as allowing us to place the Sun's magn…
Retrieval of aboveground crop nitrogen content with a hybrid machine learning method
Katja Berger, Jochem Verrelst, Jean-Baptiste Féret +4
Hyperspectral acquisitions have proven to be the most informative Earth observation data source for the estimation of nitrogen (N) content, which is the main limiting nutrient for…
Lithium depletion and angular momentum transport in solar-type stars
T. Dumont, A. Palacios, C. Charbonnel +4
Transport processes occurring in the radiative interior of solar-type stars are evidenced by the surface variation of light elements, in particular Li, and the evolution of their r…
Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars
Gaia Collaboration, R. L. Smart, L. M. Sarro +420
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
Singular modules for affine Lie algebras, and applications to irregular WZNW conformal blocks
Giovanni Felder, Gabriele Rembado
We give a mathematical definition of spaces of irregular vacua/covacua in genus zero, for any simple Lie algebra, working at generic noncritical level. This uses coinvariants of af…
Vacuum Stability Conditions for Higgs Potentials with Triplets
Gilbert Moultaka, Michel C. Peyranère
Tree-level dynamical stability of scalar field potentials in renormalizable theories can in principle be expressed in terms of positivity conditions on quartic polynomial structure…
Separation of scales: Dynamical approximations for composite quantum systems
Irene Burghardt, Rémi Carles, Clotilde Fermanian Kammerer +2
We consider composite quantum-dynamical systems that can be partitioned into weakly interacting subsystems, similar to system-bath type situations. Using a factorized wave function…
K3 surfaces and cubic fourfolds with Abelian motive
Hanine Awada, Michele Bolognesi, Robert Laterveer +1
We show that cubic fourfolds with lattice of algebraic 2-cycles of rank greater than 19 have abelian and finite dimensional (in the sense of Kimura) Chow motive. This also implies…
Improved error estimates for Hybrid High-Order discretizations of Leray-Lions problems
Daniele Antonio Di Pietro, Jérôme Droniou, André Harnist
We derive novel error estimates for Hybrid High-Order (HHO) discretizations of Leray-Lions problems set in W^(1,p) with p in (1,2]. Specifically, we prove that, depending on the de…
Gaia Early Data Release 3: Summary of the contents and survey properties
Gaia Collaboration, A. G. A Brown, A. Vallenari +423
We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented…
A bound on the joint spectral radius using the diagonals
Vuong Bui
The primary aim of this paper is to establish bounds on the joint spectral radius for a finite set of nonnegative matrices based on their diagonal elements. The efficacy of this ap…
Investigating the young AU~Mic system with SPIRou: large-scale stellar magnetic field and close-in planet mass
Baptiste Klein, Jean-François Donati, Claire Moutou +12
We present a velocimetric and spectropolarimetric analysis of 27 observations of the 22-Myr M1 star AU Microscopii (Au Mic) collected with the high-resolution (0.98-2.35 …
Left Lyndon tree construction
Golnaz Badkobeh, Maxime Crochemore
We extend the left-to-right Lyndon factorisation of a word to the left Lyndon tree construction of a Lyndon word. It yields an algorithm to sort the prefixes of a Lyndon word accor…
