A homogeneous analysis of globular clusters from the APOGEE survey with the BACCHUS code. I. The Northern clusters
T. Masseron, D. A. García-Hernández, Sz. Mészáros +12
We analyze a large sample of 885 GCs giants from the APOGEE survey. We used the Cannon results to separate the red giant branch and the asymptotic giant branch stars, not only allo…
Neural correlates of episodic memory in the Memento cohort
Stéphane Epelbaum, Vincent Bouteloup, Jean Mangin +22
IntroductionThe free and cued selective reminding test is used to identify memory deficits in mild cognitive impairment and demented patients. It allows assessing three processes:…
Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking
C. Georgy, C. Charbonnel, L. Amard +8
Extended MS turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where the MS turn-of…
Uncovering the dynamic precursors to motor-driven contraction of active gels
Jose Alvarado, Luca Cipelletti, Gijsje Koenderink
Cells and tissues have the remarkable ability to actively generate the forces required to change their shape. This active mechanical behavior is largely mediated by the actin cytos…
Current-induced nucleation and dynamics of skyrmions in a Co-based Heusler alloy
W. Akhtar, A. Hrabec, S. Chouaieb +9
We demonstrate room-temperature stabilization of dipolar magnetic skyrmions with diameters in the range of nm in a single ultrathin layer of the Heusler alloy CoFeAl (CFA…
Fundamental limits for non-destructive measurement of a single spin by Faraday rotation
Denis Scalbert
Faraday rotation being a dispersive effect, is commonly considered as the method of choice for non-destructive detection of spin states. Nevertheless Faraday rotation is inevitably…
Excitonic emission in van-der-Waals nanotubes of transition metal dichalcogenides
T. V. Shubina, M. Remškar, V. Yu. Davydov +3
Nanotubes (NTs) of transition metal dichalcogenides (TMDs), such as MoS2 and WS2, were first synthesized more than a quarter of a century ago; nevertheless, many of their propertie…
Implementation of Control Strategies for Sterile Insect Techniques
Pierre-Alexandre Bliman, Daiver Cardona-Salgado, Yves Dumont +1
In this paper, we propose a sex-structured entomological model that serves as a basis for design of control strategies relying on releases of sterile male mosquitoes (Aedes spp) an…
A -ray determination of the Universe's star-formation history
LAT Collaboration, M. Ajello, K. Helgason +4
The light emitted by all galaxies over the history of the Universe produces the extragalactic background light (EBL) at ultraviolet, optical, and infrared wavelengths. The EBL is a…
Sound attenuation in stable glasses
Lijin Wang, Ludovic Berthier, Elijah Flenner +2
Understanding the difference between universal low-temperature properties of amorphous and crystalline solids requires an explanation of the stronger damping of long-wavelength pho…
Coupled complex Monge-Ampère equations on Fano horosymmetric manifolds
Thibaut Delcroix, Jakob Hultgren
We give necessary and sufficient conditions for existence of solutions to a general system of complex Monge-Ampère equations on Fano horosymmetric manifolds. In particular, we get…
The Higson-Roe sequence for étale groupoids II. The universal sequence for equivariant families
Moulay-Tahar Benameur, Indrava Roy
This is the second part of our series about the Higson-Roe sequence for étale groupoids. We devote this part to the proof of the universal -theory surgery exact sequence which e…
Effective approach to lepton observables: the seesaw case
Rupert Coy, Michele Frigerio
In the absence of direct evidence of new physics, any ultraviolet theory can be reduced to its specific set of low-energy effective operators. As a case study, we derive the effect…
Hybridization of topological surface states with a flat band
Sergey S. Krishtopenko, Mauro Antezza, Frédéric Teppe
We address the problem of hybridization between topological surface states and a non-topological flat bulk band. Our model, being a mixture of three-dimensional Bernevig-Hughes-Zha…
Massless Dirac fermions in III-V semiconductor quantum wells
S. S. Krishtopenko, W. Desrat, K. E. Spirin +12
We report on the clear evidence of massless Dirac fermions in two-dimensional system based on III-V semiconductors. Using a gated Hall bar made on a three-layer InAs/GaSb/InAs quan…
Unresolved Gamma-Ray Sky through its Angular Power Spectrum
M. Ackermann, M. Ajello, L. Baldini +107
The gamma-ray sky has been observed with unprecedented accuracy in the last decade by the Fermi large area telescope (LAT), allowing us to resolve and understand the high-energy Un…
Efficient swap algorithms for molecular dynamics simulations of equilibrium supercooled liquids
Ludovic Berthier, Elijah Flenner, Christopher J. Fullerton +2
It was recently demonstrated that a simple Monte Carlo (MC) algorithm involving the swap of particle pairs dramatically accelerates the equilibrium sampling of simulated supercoole…
Direct evidence of a full dipole flip during the magnetic cycle of a sun-like star
S. Boro Saikia, T. Lueftinger, S. V Jeffers +9
The behaviour of the large-scale dipolar field, during a star's magnetic cycle, can provide valuable insight into the stellar dynamo and associated magnetic field manifestations su…
Theoretical insights into the topology of molecular excitons from single-reference excited states calculation methods
Thibaud Etienne
This chapter gives an introduction to qualitative and quantitative topological analyses of molecular electronic transitions. Among the possibilities for qualitatively describing ho…
Convective cells in Betelgeuse: imaging through spectropolarimetry
A. López Ariste, P. Mathias, B. Tessore +7
We assess the ability to image the photosphere of red supergiants and, in particular Betelgeuse, through the modelling of the observed linear polarization in atomic spectral lines.…
