Phonon anomalies are commonly attributed to Fermi-surface nesting or phonon anharmonicity, but these mechanisms do not apply in all cases. Here, the authors propose a new mechanism based on electron-momentum-dependent electron-phonon coupling in the case of YNi2B2C, that could also apply to other materials.

BackgroundUnderstanding the impact of the burden of COVID-19 is key to successfully navigating the COVID-19 pandemic. As part of a larger investigation on COVID-19 mortality impact, this study aims to estimate the Potential Years of Life Lost (PYLL) in 17 countries and territories across the world (Australia, Brazil, Cape Verde, Colombia, Cyprus, F...
We derive the Whitham equations from the water waves equations in the shallow water regime using two different methods, thus obtaining a direct and rigorous link between these two models. The first one is based on the construction of approximate Riemann invariants for a Whitham-Boussinesq system and is adapted to unidirectional waves. The second on...
Despite the importance of experiment-driven research in the distributed computing community, there has been little progress in helping researchers conduct their experiments. In most cases, they have to achieve tedious and time-consuming development and instrumentation activities to deal with the specifics of testbeds and the system under study. In ...

Introduction : L’évaluation d’impact sur la santé (EIS) se développe rapidement en France. Elle est proche d’autres démarches, telles que l’évaluation de politiques publiques (EPP) avec laquelle elle est parfois confondue.But de l’étude : Cet article a pour objectifs d’identifier les similitudes et différences entre EIS et EPP et d’apprécier dans q...
Zero-error source coding when side-information (SI) may be present is a fundamental building block of interactive real-world compression systems. In this paper, we show how to use the SI at the encoder in order to lower the compression rate. Indeed, in general, without SI at the encoder, the minimum zero-error compression rate is the entropy of the...
Modern browsers give access to several attributes that can be collected to form a browser fingerprint. Although browser fingerprints have primarily been studied as a web tracking tool, they can contribute to improve the current state of web security by augmenting web authentication mechanisms. In this paper, we investigate the adequacy of browser f...

The fast-growing consumer demand drives industrial process intensification, which subsequently creates a significant amount of waste. These products are discharged into the environment and can affect the quality of air, degrade water streams, and alter soil characteristics. Waste materials may contain polluting agents that are especially harmful to...
Enterococci are long-standing members of the gastrointestinal tract of humans and many animals and they are also ubiquitously distributed in natural environments. Classically as harmless bacteria, two main species (namely Enterococcus faecalis and Enterococcus faecium) have become a leading cause of human infections, especially in hospital settings...
