RF‐Shielding of Laser‐Cut Venous Stents: Calculations, Simulations, and Experiments
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2331-2344, April 2026.ABSTRACT Purpose To develop an analytical model of the RF‐shielding of laser‐cut venous stents for different orientations and stent geometries. Methods Laser‐cut venous stents are modeled as a grid composed of circular and rectangular loops. As these loops are orthogonal they shield different components of the transmit RF field.

The finite mass beamsplitter in high power interferometers
, 2004 The beamplitter in high-power interferometers is subject to significant radiation-pressure fluctuations. As a consequence, the phase relations which appear in the beamsplitter coupling equations oscillate and phase modulation fields are generated which ...

Conundrums of Localized Surface Plasmon Resonance Biosensors
Small, Volume 22, Issue 19, 1 April 2026.Localized surface plasmon resonance (LSPR) biosensing faces fundamental conundrums arising from finite field decay lengths, environmental cross‐sensitivities, and batch variability. Competing surface, bulk, and electrostatic effects can induce red or blue spectral shifts, complicating quantification, reproducibility, and interpretation in complex or ...

Soft-Output Maximum-Likelihood Detector for Quadrature Spatial Modulation
Nigerian Journal of Technological Development, 2018 Spatial modulation (SM) presents a pragmatic approach for transmitting information, where the modulator uses well known amplitude/phase modulation (APM) techniques such as phase shift keying (PSK) and quadrature amplitude modulation (QAM), but also ...

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.ABSTRACT Previous studies of teleconnection (TC) impacts on Terrestrial Water Storage Anomalies (TWSA) rarely focus on Vietnam or on the nonstationary nature of TC–TWSA relationships. This study addresses these gaps by examining both stationary and nonstationary TC influences on TWSA using correlation analysis (Pearson and cross‐spectral methods) and ...
