Field measurements and model predictions of turbulent kinetic energy in canopies of sparse vegetation under tidal flows

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract The presence of vegetation in aquatic environments alters hydrodynamics and sediment resuspension. A recent paradigm has suggested that turbulent kinetic energy (TKE) serves as a better predictor of sediment transport in aquatic canopies than bed shear stress.

Analytical Model of Velocity Distribution and Penetration Characteristics in Water‐Level Fluctuation Zone With Vegetation

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract As a critical ecological transition zone between aquatic and terrestrial ecosystems, the water‐level fluctuation zone significantly influences flow structure through vegetation morphology. Conventional analytical velocity models inadequately address the variation in vegetation with water depth.

Microtubule Inhibitors Induce Cross‐Resistance to Osimertinib Through CaMKII Activation in EGFR‐Mutated NSCLC

Cancer Science, Volume 117, Issue 2, Page 418-428, February 2026.
Eighteen‐week treatment with microtubule inhibitors induces resistance to osimertinib in EGFR‐mutated NSCLC cells. Vinorelbine‐ and paclitaxel‐resistant cells showed activation of FZD7 and CaMKII and increased sensitivity to CaMKII inhibition, with additive or synergistic effects when combined with osimertinib.

Preservación de madera con taninos

Madera y Bosques, 2016
En este trabajo se exponen tres ideas para la aplicación de taninos contra posibles agentes destructores de madera. Se hace una descripción somera de los mecanismos naturales de defensa de los árboles con el fin de tratar de empezar a comprenderlos. Estos mecanismos ocurren como consecuencia de estímulos o ataques externos.

Photoperiod–Temperature Interactions in a Changing Climate: A Review of Plant Phenological Responses

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Climate change is reshaping plant phenology and species distributions, especially in temperate and boreal ecosystems, where advances in spring events have already extended the growing season. While temperature has been the primary focus of many studies, the role of photoperiod—a stable, latitude‐dependent cue—remains underexplored.

Submerged Flexible Canopies Produce Weaker Shear‐Layer Turbulence and Mitigate Sediment Transport, Compared to Rigid Model Canopies

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Submerged vegetation canopies are widespread and influence bedload sediment transport in rivers, wetlands and deltas. However, the impacts of submerged canopies on sediment transport have not been fully quantified. This study used model Vallisneria denseserrulata to construct submerged flexible canopies in a mobile bed.
