The Wade's rules and Lipscomb's styx approach constitute a conceptual basis of chemical bonding in closo hydroborane clusters and similar compounds. Based on 3‐center electron sharing indices obtained from DFT wavefunctions, the DR approach for analysis of multicenter bonding in clusters and intermetallic compounds is presented.

MHD turbulence in the intracluster medium [PDF]
AbstractIn this work we discuss the turbulent evolution of structures in the intracluster medium based on the two fluid approximations: MHD and collisionless plasma under Chew Goldberger Low (CGL) closure. Turbulence excited by galactic motions and gas inflow in intracluster medium will develop in very different ways considering the two fluid ...

XRISM Reveals Low Nonthermal Pressure in the Core of the Hot, Relaxed Galaxy Cluster A2029
We present XRISM Resolve observations of the core of the hot, relaxed galaxy cluster Abell 2029 (A2029). We find that the line-of-sight bulk velocity of the intracluster medium (ICM) within the central 180 kpc is at rest with respect to the brightest ...

Turbulence decay in the density-stratified intracluster medium
Turbulence evolution in a density-stratified medium differs from that of homogeneous isotropic turbulence described by the Kolmogorov picture. We evaluate the degree of this effect in the intracluster medium (ICM) with hydrodynamical simulations. We find

Target Material Property‐Dependent Cluster Analysis of Inorganic Compounds
A method to interpret machine learning prediction models for detecting promising material groups in terms of given material properties is developed. The developed method is validated by categorizing more than 1000 oxides into material groups, considering both basic descriptors of the composition and crystal structure and target properties such as the ...

Non-thermal particles in the intergalactic and intracluster medium [PDF]
I present a review of nonthermal processes in the large scale structure of the universe. After examining the properties of cosmological shock waves and their role as particle accelerators, I discuss the main observational facts, from radio to \gr and describe the processes that are thought be responsible for the observed nonthermal emissions.

Abstract This study examines the integration of digital and circular economy (CE) strategies in small and medium enterprises (SMEs) and their impact on innovation. The research uses data from the Eurobarometer survey conducted by the European Commission, which includes a sample of 16,365 SMEs.

We present the first results of one extremely high-resolution, nonradiative magnetohydrodynamical cosmological zoom-in simulation of a massive cluster with a virial mass of M _vir = 2.0 × 10 ^15 solar masses. We adopt a mass resolution of 4 × 10 ^5 M _⊙

Buoyancy Instabilities in a Weakly Collisional Intracluster Medium
The intracluster medium of galaxy clusters is a weakly collisional, high-beta plasma in which the transport of heat and momentum occurs primarily along magnetic-field lines.

Investigation of Properties of the Intercluster Medium Rich Clusters of Galaxies [PDF]
The statistical analysis of properties of 213 rich clusters of galaxies is performed. The existence of correlations between the X-ray luminosity and the temperature of the intracluster medium and between the X-ray luminosity and the velocity dispersion of the galaxies is confirmed.
