Mental chronometry in the pocket? Timing accuracy of web applications on touchscreen and keyboard devices
Authors: Pronk Thomas , Wiers Reinout W. , Molenkamp Bert , Murre Jaap 
Published: December 2019

AbstractWeb applications can implement procedures for studying the speed of mental processes (mental chronometry) and can be administered via web browsers on most commodity desktops, laptops, smartphones, and tablets. This approach to conducting mental chronometry offers various opportunities, such as increased scale, ease of data collection, and access to specific samples. However, validity and reliability may be threatened by less accurate timing than specialized software and hardware can offer. We examined how accurately web applications time stimuli and register response times (RTs) on commodity touchscreen and keyboard devices running a range of popular web browsers. Additionally, we explored the accuracy of a range of technical innovations for timing stimuli, presenting stimuli, and estimating stimulus duration. The results offer some guidelines as to what methods may be most accurate and what mental chronometry paradigms may suitably be administered via web applications. In controlled circumstances, as can be realized in a lab setting, very accurate stimulus timing and moderately accurate RT measurements could be achieved on both touchscreen and keyboard devices, though RTs were consistently overestimated. In uncontrolled circumstances, such as researchers may encounter online, stimulus presentation may be less accurate, especially when brief durations are requested (of up to 100 ms). Differences in RT overestimation between devices might not substantially affect the reliability with which group differences can be found, but they may affect reliability for individual differences. In the latter case, measurement via absolute RTs can be more affected than measurement via relative RTs (i.e., differences in a participant’s RTs between conditions).
Physical Constraints from Near-infrared Fast Photometry of the Black Hole Transient GX 339–4

Abstract
We present results from the first multi-epoch X-ray/IR fast-photometry campaign on the black hole transient GX 339–4, during its 2015 outburst decay. We studied the evolution of the power spectral densities finding strong differences between the two bands. The X-ray power spectral density follows standard patterns of evolution, plausibly reflecting changes in the accretion flow. The IR power spectral density instead evolves very slowly, with a high-frequency break consistent with remaining constant at 0.63 ± 0.03 Hz throughout the campaign. We discuss this result in the context of the currently available models for the IR emission in black hole transients. While all models will need to be tested quantitatively against this unexpected constraint, we show that an IR-emitting relativistic jet that filters out the short-timescale fluctuations injected from the accretion inflow appears as the most plausible scenario.
Catastrophic Events in Protoplanetary Disks and Their Observational Manifestations
Authors: Demidova Tatiana V. , Grinin Vladimir P. 
Published: December 2019

Abstract
Observations of protoplanetary disks with high angular resolution using an ALMA interferometer showed that ring-shaped structures are often visible in their images, indicating strong disturbances in the disks. The mechanisms of their formation are vividly discussed in the literature. This article shows that the formation of such structures can be the result of destructive collisions of large bodies (planetesimals and planetary embryos) accompanied by the formation of a large number of dust particles, and the subsequent evolution of a cloud of dust formed in this way.
Upscattered Cocoon Emission in Short Gamma-Ray Bursts as High-energy Gamma-Ray Counterparts to Gravitational Waves

Published: December 2019

Abstract
We investigate prolonged engine activities of short gamma-ray bursts (SGRBs), such as extended and/or plateau emissions, as high-energy gamma-ray counterparts to gravitational waves (GWs). Binary neutron-star mergers lead to relativistic jets and merger ejecta with r-process nucleosynthesis, which are observed as SGRBs and kilonovae/macronovae, respectively. Long-term relativistic jets may be launched by the merger remnant as hinted in X-ray light curves of some SGRBs. The prolonged jets may dissipate their kinetic energy within the radius of the cocoon formed by the jet–ejecta interaction. Then the cocoon supplies seed photons to nonthermal electrons accelerated at the dissipation region, causing high-energy gamma-ray production through the inverse Compton scattering process. We numerically calculate high-energy gamma-ray spectra in such a system using a one-zone and steady-state approximation, and show that GeV–TeV gamma-rays are produced with a duration of 102–105 s. They can be detected by Fermi/LAT or CTA as gamma-ray counterparts to GWs.
A study into the modes of the VVER-1000 RCP starting in an earlier inoperative loop
Authors: Bragin Iliya Ye. , Belozerov Vladimir I. 
Published: December 2019

To simulate the mode of the RCP starting in an earlier inoperative loop, KORSAR/GP, a code supporting coupled numerical modeling of neutronic and thermal-hydraulic transients in a VVER reactor plant in operating and emergency conditions, was chosen as the computational tool.
Studying these modes using thermal-hydraulic codes makes it possible to analyze the course of transients and certain emergency processes without using commercial test procedures, which contributes to laying the groundwork for addressing the issues involved in ensuring the reliability, operating safety and efficiency of nuclear power plants.
Increased requirements to the safety of NPPs identify the need for avoiding excessive conservatism in the analysis based on which requirements to safety systems are formulated, as well as for enhancing the knowledge of the regularities of thermal-hydraulic transients based on advanced computer programs (or codes) designed for improved computational analysis of non-stationary thermal hydraulics in the water-cooled reactor circulation circuits in emergency and transient modes relying on inhomogeneous non-equilibrium mathematical models of two-phase flows and on a detailed description of the physical transient regularities.
The purpose of the study is to analyze computationally the starting of a VVER-1000 RCP in an earlier inoperative loop at different reactor plant power values. To do this, one requires to develop the VVER-1000 reactor primary circuit computational pattern to model the transient taking place as one RCP is started, to conduct a further analysis, and to compare the key monitored reactor coolant and core parameters (power, temperature, flow rate, etc.).
Le droit, arme économique et géopolitique des États-Unis
Authors: Leblanc-Wohrer Marion 
Published: December 2019

Depuis les années 2000, les États-Unis ont développé une politique juridique extérieure d’abord vouée à la lutte contre la corruption, aujourd’hui considérablement étendue. L’effort de moralisation des relations économiques internationales est désormais difficile à distinguer de la défense d’intérêts proprement américains. Quant aux sanctions, elles constituent une puissante arme économique et diplomatique, dont on voit à la fois l’efficacité internationale et les limites dans le cas iranien.
La France et le nucléaire iranien : enjeux bureaucratiques et politique étrangère
Authors: Beaud Guillaume 
Published: December 2019

Les décisions de politique étrangère sont des produits complexes, qui dépendent aussi de l’influence de divers groupes bureaucratiques, aux cultures et aux légitimités spécifiques. Le cas de la négociation sur le nucléaire iranien ne fait pas exception, qui a vu s’opposer en France une sensibilité de tradition « régionaliste » et « gaullo-mitterrandienne », à une sensibilité plus « occidentaliste », qui tendra à s’imposer dans le jeu institutionnel sous les présidences Sarkozy et Hollande.
La pierre d’aimant dans la poésie humaniste : « secrettes approches » d’un lieu commun
Authors: Pichot Pierre-Élie 
Published: December 2019

Dans l’histoire naturelle pré-moderne, l’attraction magnétique constitue un mystère inexpliqué. A la Renaissance, les poètes s’en emparent alors pour exprimer toutes sortes de vertus attractives inexplicables : l’amour bien sûr, mais aussi l’amitié, la foi, l’adoration… Dès lors le motif de la pierre d’aimant ne peut pas être étudié à travers le prisme d’une catégorie poétique unique, puisqu’il transgresse les frontières des genres et des registres. Il peut en revanche être rapporté à certaines théories de la Renaissance du rapport entre l’inspiration poétique et les prodiges naturels. Cet article distingue trois moments dans la matérialisation des théories poétiques par le lieu commun de la pierre d’aimant : d’abord l’aimant comme image de la fureur poétique ficinienne, puis comme défense et illustration de l’autorité poétique du poète ; enfin son abandon par les poètes de salons, qui relèguent la pierre d’aimant dans le domaine de la prose cartésienne.
