Radial TRASE: 2D RF encoding through mechanical rotation and active digital decoupling

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 987-1001, February 2026.
Abstract Purpose Two‐dimensional (2D) transmit array spatial encoding (TRASE) previously required four radiofrequency fields; however, interactions between transmit (Tx) array elements caused significant challenges for 2D imaging. Here, we present a low‐cost, 2D radial encoding scheme (Radial TRASE) using a simplified two‐coil array.

Structure–Performance Correlation in PAN Nanofibers Reinforced With Carbon Nanotubes and Graphene Nanoplatelets

open access: yesPolymer Engineering &Science, Volume 66, Issue 2, Page 753-768, February 2026.
Electrospun polyacrylonitrile (PAN) fibers reinforced with carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) exhibit enhanced dielectric properties due to improved interfacial polarization and conductive network formation. Hybrid nanofillers enable morphology control and synergistic tuning of electrical performance, offering a promising route ...

Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr

open access: yesJournal of Animal Ecology, Volume 95, Issue 2, Page 359-376, February 2026.
Our study reveals that brook charr adopt distinct ‘warm’ and ‘cool’ behavioural tactics to balance foraging and thermal stress in stratified lakes. By linking fine‐scale thermal movements to morphology, we show how temperature‐driven habitat use promotes individual specialization and potential ecotypic divergence under climate change.
