Generalized derivations of $ω$-Lie algebras

Kavli Affiliate: Jie Shan | First 5 Authors: Yin Chen, Yin Chen, , , | Summary: This article explores the structure theory of compatible generalized derivations of finite-dimensional $ω$-Lie algebras over a field $mathbbK$. We prove that any compatible quasiderivation of an $ω$-Lie algebra can be embedded as a compatible derivation into a larger $ω$-Lie […]

The Origin of the Gas and Its Low Star Formation Efficiency in Quiescent Galaxies

Kavli Affiliate: Yingjie Peng | Summary:Quiescent galaxies (QGs) typically have little cold gas to form stars. The discovery of gas-rich QGs challenges our conventional understanding of the evolutionary paths of galaxies. We take advantage of a new catalog of nearby, massive galaxies with robust, uniformly derived physical properties to better understand the origin of gas-rich […]

Analysis of Information Loss on Composition Measurement in Stiff Chemically Reacting Systems

Kavli Affiliate: Long Zhang | First 5 Authors: Yiming Lu, Xu Zhu, Long Zhang, Hua Zhou, | Summary: Gas sampling methods have been crucial for the advancement of combustion science, enabling analysis of reaction kinetics and pollutant formation. However, the measured composition can deviate from the true one because of the potential residual reactions in […]

The reliability of hybrid functionals for accurate fundamental and optical gap prediction of bulk solids and surfaces

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Francisca Sagredo, María Camarasa-Gómez, Francesco Ricci, Aurélie Champagne, Leeor Kronik | Summary: Hybrid functionals have been considered insufficiently reliable for the prediction of band gaps in solids and surfaces. We revisit this issue with a new generation of optimally-tuned range-separated hybrid functionals, focusing on the reconstructed […]

A Hierarchical Shock Model of Ultra-High-Energy Cosmic Rays

Kavli Affiliate: Roger Blandford | Summary:We propose that a hierarchical shock model$unicodex2014$including supernova remnant shocks, galactic wind termination shocks, and accretion shocks around cosmic filaments and galaxy clusters$unicodex2014$can naturally explain the cosmic ray spectrum from ~1 GeV up to ~200 EeV. While this framework applies to the entire cosmic ray spectrum, in this work, we […]
