Interference and noise analysis for hybrid FSO/RF-based 6G mobile backhaul
ETRI Journal, 2022 Optical wireless communication, or free space optics, is a promising solution for backhauls in sixth-generation mobile systems. However, the susceptibility of optical links to weather conditions has led to FSO links being furnished with radio frequency ...

Land Cover Shapes Altitudinal Land Surface Warming Patterns Across Switzerland
Earth's Future, Volume 14, Issue 7, July 2026.Abstract Mountainous regions are characterized by steep vertical gradients in temperature which in turn shape land cover and ecosystems that are differently affected by climate change. Here, we show that both stable and changing land covers have an important influence on land surface temperature (LST) trends in Switzerland, based on almost four decades

Human Brain Mapping, Volume 47, Issue 7, May 2026.Using rTMS over the frontal eye field combined with fMRI, we demonstrate that disrupting attentional control slows responses and reduces cortical activity for neutral faces while sparing or amplifying amygdala responses to fearful faces, highlighting a disinhibitory effect of TMS on top‐down control.
