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

Neural Substrates of Attentional Control During Emotional Processing: Evidence From rTMS–fMRI Targeting the Frontal Eye Field

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.

Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, Volume 55, Issue 3, Page 1608-1638, May 2026.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Turbulence‐Resilient Coherent Receiver Array on CMOS‐Compatible Silicon Photonics for Free Space Optical Communications

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
A CMOS‐compatible silicon‐photonic 4 × 4 coherent receiver array spatially samples turbulence‐distorted wavefronts and, with maximum‐ratio combining, enables signal recovery. Experimental BPSK tests under moderate turbulence approach theoretical combining efficiency, reducing BER from 1E‐2 to 1E‐15.
