Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

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 ...

Shock Acceleration in the Intracluster Medium: Implications of Micromirror Confinement

The Astrophysical Journal
Merging galaxy clusters exhibit strong observational evidence for efficient particle acceleration in the intracluster medium (ICM), particularly in the form of synchrotron-emitting radio relics and halos. Cosmic-ray (CR) electrons are likely accelerated (

Galaxy Cluster Outskirts from the Thermal SZ and Non-Thermal Synchrotron Link

Galaxies, 2016
Galaxy cluster merger shocks are the main agent for the thermalization of the intracluster medium and the energization of cosmic ray particles in it. Shock propagation changes the state of the tenuous intracluster plasma, and the corresponding signal ...

Role of Anharmonicity and Bimetallic Intermixing in the IR and Raman Spectra of Cun$_{n}$ and Pdn$_{n}$Cu6−n$_{6-n}$ Clusters (n<7$n\lt 7$). Ab Initio Benchmarking of DFT

Small Structures, Volume 7, Issue 5, May 2026.
High‐level ab initio and density functional theory calculations reveal a structural and spectroscopic transition from pla nar Cu6 to three‐dimensional Pd6, whose lowest energy triplet state undergoes a Jahn‐Teller distortion. This evolution from molecule‐like to metal‐like bonding produces distinct infrared and Raman fingerprints, providing reliable ...

Knowledge, Attitudes, and Practices Regarding Infection Prevention Among Healthcare Professionals and Their Predictors at a Tertiary Hospital in Ethiopia: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background Assessing healthcare professionals' existing knowledge, attitudes, and practices (KAP) regarding infection prevention and control (IPC) is essential for identifying gaps and informing strategies to mitigate healthcare‐associated infections (HCAIs).

Turbulence in the intracluster medium: simulations, observables, and thermodynamics [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
We conduct two kinds of homogeneous isotropic turbulence simulations relevant for the intracluster medium (ICM): (i) pure turbulence runs without radiative cooling; (ii) turbulent heating$+$radiative cooling runs with global thermal balance. For pure turbulence runs in the subsonic regime, the rms density and surface brightness (SB) fluctuations vary ...

IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 109-127, March/April 2026.
ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.

Cosmological simulations of the intracluster medium [PDF]

Monthly Notices of the Royal Astronomical Society, 2004
We investigate the properties of the intracluster medium (ICM) that forms within N-body/hydrodynamical simulations of galaxy clusters in a \LambdaCDM cosmology. When radiative cooling and a simple model for galactic feedback are included, our clusters have X-ray luminosities and temperatures in good agreement with observed systems, demonstrating the ...
