Use of Automation Technologies and Data Mining in Speech Recognition for Autism
Brain and Behavior, Volume 16, Issue 2, February 2026.Pipeline analyzes clinical and naturalistic speech using LENA, wav2vec 2.0, and foundation‐model ASR (Whisper) to enable scalable ASD detection and severity estimation. Future work integrates benchmarking, privacy‐preserving collaboration (federated learning), and explainable, edge‐ready AI for clinically credible assessment and longitudinal monitoring.

Near-Optimal Design for Hybrid Beamforming in mmWave Massive Multi-User MIMO Systems
IEEE Access, 2020 Millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems can obtain sufficient beamforming gains to combat severe path loss in signal propagation. The hybrid (analog/digital) beamforming with multiple data streams can be utilized to

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

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 ...

Evidence for Virtual Source‐Receiver Refractions in Cross Correlations of Infrasonic Ambient Noise
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Seasonal variability in source activity and atmospheric temperature were retrieved from 11 years of infrasonic ambient noise. Variable lag times between an array and single microbarometer were obtained from envelopes of cross‐correlation functions. Beamforming and one‐bit normalization significantly enhanced the stationary phase.

Atmospheric Specifications for Infrasound Studies: 2. The Added Value of a High‐Top Model, UA‐ICON
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.Abstract Infrasound monitoring activities that deal with long‐range acoustic propagation, as within the Comprehensive Nuclear‐Test‐Ban Treaty's (CTBT), need accurate and operational modeling of the atmosphere up to the lower thermosphere. Yet, operational meteorological products issued by weather services are topped at around 80 km altitude with a ...
