Arrhythmic expression signatures of circadian clock‐associated transcription factors and chronic circadian disruption contribute to advanced prostate cancer growth

International Journal of Cancer, Volume 158, Issue 3, Page 775-789, 1 February 2026.
What's new? Circadian rhythm disruption potentially fuels prostate cancer progression. The mechanisms and signaling molecules contributing to hormonal tumorigenesis, however, remain largely undefined. In this study, circadian expression patterns of core‐circadian controlled genes (CCCGs) and nuclear receptors (NRs) were investigated in advanced ...

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

Time and phase alignment of distributed gateways: Theoretical analysis and experimental demonstration

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 47-59, January/February 2026.
The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

5G new radio multiuser precoding in geostationary satellite networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 60-72, January/February 2026.
This work evaluates the standardized 5G new radio codebooks for closed‐loop multiuser precoding in GEO multibeam scenarios and derives a list of recommended 3GPP standard modifications for a proper support to GEO mission needs. Summary The multiuser precoding procedures standardized by the 3rd Generation Partnership Project (3GPP) for new radio (NR ...

Signal Processing for the Cluster Wideband Data Burst Mode

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The Wideband Data instrument is part of the Cluster spacecraft Wave Experiment Consortium. Its primary data path is a direct connection to the spacecraft data handling system providing real time downlink to the ground stations of the Deep Space Network and Panska Ves Observatory.
