Machine Learning–Driven Insights Into the Self‐Assembly of Gold–Thiolate Nanoclusters
Aggregate, Volume 7, Issue 5, May 2026.A machine‐learned atomistic potential, trained by data from density‐functional theory calculations on thiolate‐protected gold nanoclusters, is applied to investigate cluster–cluster reactions in 0.1 µs timescale molecular dynamics simulations. Starting from a few experimentally known cluster stoichiometries and structures, the simulations show a ...

XMM-Newton observation of M 87 - I. Single-phase temperature structure of intracluster medium
, 2002 We report the results of a detailed analysis of the temperature structure of the X-ray emitting plasma halo of M 87, the cD galaxy of the Virgo Cluster. Using the MEKAL model, the data provide strong indications that the intracluster medium has a single ...

Multiscale analysis of turbulence evolution in the density-stratified intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The diffuse hot medium inside clusters of galaxies typically exhibits turbulent motions whose amplitude increases with radius, as revealed by cosmological hydrodynamical simulations. However, its physical origin remains unclear. It could either be due to

Histidine Protonation and the Oxidizing Power of the Oxygen‐Evolving Complex
ChemPhotoChem, Volume 10, Issue 5, May 2026.Protonation of D1‐His337 governs the oxidizing power of the Mn4CaO5 cluster in photosystem II. Its singly protonated form is unstable, resulting in histidine oxidation and disruption of Mn oxidation, whereas the doubly protonated form is stable and upshifts the cluster redox potential, enabling efficient water oxidation.

Energy Science &Engineering, Volume 14, Issue 5, Page 2514-2538, May 2026.On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Calcium-rich gap transients: solving the calcium conundrum in the intracluster medium [PDF]
, 2014 X-ray measurements suggest that the abundance of calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone.

A Generative Model for Realistic Galaxy Cluster X-Ray Morphologies
The Astrophysical JournalThe X-ray morphologies of clusters of galaxies display significant variations, reflecting their dynamical histories and the nonlinear dependence of X-ray emissivity on the density of the intracluster gas. Qualitative and quantitative assessments of X-ray
