Polymers for Advanced Technologies, Volume 37, Issue 10, October 2026.ABSTRACT Compliant optical waveguides are promising candidates for stress/strain sensing in soft robotics and personalized healthcare. While poly(dimethylsiloxane) (PDMS) offers a robust platform, enhancing sensitivity and integrating localized visual indicators for pressure threshold detection remains an active area of research.

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

River, Volume 5, Issue 3, Page 369-387, August 2026.Abstract Estimating suspended sediment concentration (SSC) in river channels is essential for understanding hydro‐sedimentological processes, managing water quality, and conserving aquatic ecosystems. This study evaluated different empirical equations to estimate SSC in the lower Madeira River and analyzed its hydro‐sedimentary dynamics based on MODIS ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract At subauroral latitudes, discrete auroras, such as strong thermal emission velocity enhancement and stable auroral red arcs, have been extensively studied. On the other hand, diffuse emissions at subauroral latitudes have not been studied well.

Space-Time Codes for Wireless Optical Communications
EURASIP Journal on Advances in Signal Processing, 2002 A space-time channel coding technique is presented for overcoming turbulence-induced fading in an atmospheric optical heterodyne communication system that uses multiple transmit and receive apertures. In particular, a design criterion for minimizing the

Elastic Properties of Titan Tholins Revealed by Brillouin Spectroscopy
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan's atmosphere, are widely regarded as analogs to organic surface materials on the Saturnian moon. Their mechanical properties are critical for understanding the evolution of Titan's geomorphology and crustal layering.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.Abstract Recent work has demonstrated that convection‐permitting models often produce a greater number of precipitating convective cells compared to radar observations. Congestus‐depth cells contribute most to the bias, which are colloquially termed “popcorn convection.” This study explores warm‐phase microphysical contributions to the bias using ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...
