Longitudinal Variability of Pre‐Midnight Equatorial Plasma Bubbles Under Disturbed Geomagnetic Conditions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

A Universal Hybrid Model‐Free Deep Quantum–Transfer Learning Controller Enhanced By Grey Wolf Optimization for DC–DC Boost Converters With Hardware‐in‐Loop Validation

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a universal hybrid model‐free quantum–transfer learning controller with enhanced online grey wolf optimization algorithm for DC–DC boost converter. This system has the characteristics of non‐minimum phase behavior, parasitic effects, and fractional‐order dynamics because of high frequency operation.

Generalized Spatial Modulation in Indoor Wireless Visible Light Communication

, 2016
In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses N-t light emitting diodes (LED), but activates only N-a of them at a given time.

Wetland location and captive breeding influence trans‐Mediterranean movements in the endangered Marbled Duck (Marmaronetta angustirostris)

Ibis, Volume 168, Issue 1, Page 245-258, January 2026.
Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.
