Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Turbidity currents are destructive flows that are hazardous to critical seafloor infrastructure on submarine slopes because run‐up heights can be 10–100s of meters, as their relative density is 2–3 orders of magnitude lower than terrestrial flows. Currently, risk analysis is hindered by poor prediction of run‐up heights that are mainly derived

Integral method from even to odd order for trigonometric B-spline basis
AIMS MathematicsThe conventional trigonometric B-spline basis of odd order for piecewise trigonometric polynomial space possesses a lot of good modeling properties. However, its order cannot be increased by the integral method like B-spline because of the particularity ...

Ecology and Evolution, Volume 16, Issue 2, February 2026.We combined multiple‐covariate distance sampling (MCDS) with habitat modeling to estimate the abundance and habitat associations of the vulnerable Asian houbara (Chlamydotis macqueenii) in central Iran. Line‐transect surveys in spring 2022 yielded an estimated density of 0.53 individuals/km2 (~5293 birds), with nearly identical results from ...

Nanophotonics, Volume 15, Issue 3, 12 February 2026.This work proposes OAM‐encoded CNN based on cascaded on‐chip OAM converters and multiplexers. The footprint of inverse‐designed converters is 5 μm × 4 μm and the maximum conversion efficiency of OAM reaches 88%. The OAM‐encoded optical CNN was built using this device, achieving 98.0% accuracy on MNIST and 86.1% accuracy on Fashion‐MNIST classification.
