Microbial metabolites in tumor epigenetic regulation

iMeta, Volume 5, Issue 1, February 2026.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

A Climatology of Heatwaves Over Greece for the Period 1960–2022

International Journal of Climatology, Volume 46, Issue 2, February 2026.
This research examines the spatiotemporal evolution of heatwaves in Greece from 1960 to 2022, utilising a long timeseries of homogenised high‐quality data with broad spatial coverage. It focuses on identifying heatwaves using verified definitions, introducing spatial and intensity classifications to understand their diverse regional variations ...

Data-Driven Beam-to-Gateway Matching and Adaptive Load Balancing for Multi-Beam GEO Satellite Systems

IEEE Open Journal of the Communications Society
Resource allocation, traffic steering, and load balancing in multi-gateway, multi-beam geostationary (GEO) satellite communication (SatCom) networks, particularly in the extremely high frequency (EHF) bands (Ka, Q, and V), face critical challenges due to

Broadband Millimeter-Wave Front-End Module Design Considerations in FD-SOI CMOS vs. GaN HEMTs

Applied Sciences
Millimeter-wave (mm-Wave) phased array systems need to meet the transmitter (Tx) equivalent isotropic radiated power (EIRP) requirement, and that depends mainly on the design of two key sub-components: (1) the antenna array and (2) the Tx power amplifier

Composite Fermion Metals from Dyon Black Holes and S-Duality

, 2010
We propose that string theory in the background of dyon black holes in four-dimensional anti-de Sitter spacetime is holographic dual to conformally invariant composite Dirac fermion metal.
