Remote Sensing in Ecology and Conservation, EarlyView.The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this

A circuit-theoretic approach to the design of quadruple-mode broadband microstrip patch antennas [PDF]
, 2008 A novel method for the design of broadband patch antennas is described. The approach taken is to broadside couple two dual-mode patch antennas, resulting in a quad resonance antenna.

Versatile High‐Sensitivity EPR Using Superconducting Spiral Microresonators
Small Methods, EarlyView.A significant sensitivity enhancement in conventional X‐band pulsed EPR is achieved using planar spiral microresonators fabricated from high‐temperature superconducting YBCO. Fully compatible with standard instrumentation, the approach enables high‐fidelity spin control under typical sample conditions.

A Crystalline Bismuth(II) Radical Anion: Synthesis, Characterization, and Reactivity
Angewandte Chemie, Volume 137, Issue 49, December 1, 2025.A T‐shaped Bi(III) trisamide featuring a sterically demanding NNN pincer ligand was prepared. The planarization of the Bi center furnishes a lowest unoccupied molecular orbital with distinct Bi(6p) orbital character which unlocks clean one‐electron reduction to afford a crystalline Bi(II) radical anion.

steel research international, EarlyView.Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

The Journal of Physiology, EarlyView.Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Enhancing the Nonlinear Optical Response Using Multifrequency Gold-Nanowire Antennas
Physical Review Letters, 2012 We introduce and experimentally demonstrate the concept of multifrequency optical antennas that are designed for controlling the nonlinear response of materials. These antennas consist of two arms of different lengths, each resonant with one of the incoming frequencies. They are embedded in a nonlinear medium (indium tin oxide) that acts as a receiver.
