Optimized Joint Relay and Antenna Selection for Enhanced Full‐Duplex Relay Networks

Engineering Reports, Volume 8, Issue 7, July 2026.
This study proposes a joint relay and antenna selection strategy for full‐duplex amplify‐and‐forward relay networks. By adaptively optimizing transmitter–receiver configurations based on channel conditions, the method reduces self‐interference, lowers outage probability, and symbol error rate, and enhances spectral efficiency, offering a scalable ...

How do gestural interactions support visuospatial cognition in STEM learning?

British Journal of Educational Technology, Volume 57, Issue 4, Page 1140-1162, July 2026.
Abstract Existing literature shows that touchscreen devices can support learning of visuospatially rich STEM content. However, the mechanisms by which touchscreen devices support cognition in learning remains unclear. This study examined how gestural interactions afforded by touchscreen devices support visuospatial cognition in STEM learning by ...

A Journey Into a Traveler's Mental Map: Duration, Distance, and Speed Experienced in High‐Speed Trains

Cognitive Science, Volume 50, Issue 7, July 2026.
Abstract Our study investigates how high‐speed transport affects humans’ perception of time, space, and speed. We tested 247 passengers traveling on the French Paris‐Lyon high‐speed train (TGV) who estimated the traveled distance, elapsed duration, and instantaneous and average speeds, while rating their confidence, felt speed of time passage, and ...

Constitution and function of intergenic genome regions in cultivated versus annual wild soybean in China

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 2105-2127, July 2026.
Three‐case restricted two‐stage multi‐locus multi‐allele genome‐wide association study identified main‐effect genes and detected the regulatory effects of intergenic loci on genes, enabling comprehensive dissection of the genic‐intergenic genetic system for quantitative traits and providing a strategy for studying their genetic basis.
