The X-ray Luminosity - Velocity Dispersion relation in the REFLEX Cluster Survey [PDF]
, 2003 We present an estimate of the bolometric X-ray luminosity - velocity dispersion L_x - sigma_v relation measured from a new, large and homogeneous sample of 171 low redshift, X-ray selected galaxy clusters.

Isomorphic Control in Energy Storage Systems Based on Graph‐Based Digital Twins
Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.This paper proposes a graph‐based framework leveraging Activity‐on‐Edge networks to establish structural isomorphism between virtual models and physical controllers. Validated through a Mixed‐Integer Linear Programming‐based Automatic Generation Control strategy, the architecture effectively bridges the implementation gap, ensuring deterministic real ...

Chemical Evolution Of Galaxies And Intracluster Medium [PDF]
, 2004 In this series of lectures I discuss the basic principles and the modelling of the chemical evolution of galaxies. In particular, I present models for the chemical evolution of the Milky Way galaxy and compare them with the available observational data.

Buoyancy Instabilities in a Weakly Collisional Intracluster Medium
, 2012 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.

Info‐KMeans: Enhancing Wireless Sensor Network Lifetime Through Information‐Aware Clustering
IET Wireless Sensor Systems, Volume 16, Issue 1, January/December 2026.This paper introduces info‐kmeans, a two‐stage wireless sensor network (WSN) protocol, that uses conditional‐entropy‐based sleep scheduling to deactivate informationally redundant nodes, then applies k‐means clustering only to the remaining information‐rich active nodes for energy‐efficient data forwarding.

Quantifying the Unwinding Due to Ram Pressure Stripping in Simulated Galaxies
GalaxiesGalaxies moving through the gas of the intracluster medium (ICM) experience ram pressure stripping, which can leave behind a gas tail. When a disk galaxy receives the wind edge-on, however, the characteristic signature is not a typical jellyfish tail ...

A Systematic Review of VANET Routing Protocols for Intelligent Transport Systems (ITSs)
Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.The swift improvement of wireless communication technology has aided the creation of vehicular ad hoc networks (VANETs) as a revolutionary option for the realization of intelligent transportation systems (ITSs). VANETs facilitate seamless communication between vehicles and infrastructure (V2I) and among the vehicles themselves (V2V). These networks can

Simulating the Arrival of the Southern Substructure in the Galaxy Cluster Abell 1758
The Astrophysical JournalAbell 1758 ( z ∼ 0.278) is a galaxy cluster composed of two structures, A1758N and A1758S, separated by ∼2.2 Mpc. The northern cluster is itself a dissociative merging cluster that has already been modeled by dedicated simulations.
