Functional Variation in the Feeding Apparatus of Charadriiform Shorebirds With Emphasis on Bill‐Tip Organs and Micro Tongue Tip Spines

Journal of Morphology, Volume 287, Issue 9, September 2026.
Comparative morphological analyses of shorebird feeding apparatus revealed substantial variation in bill‐tip organs and micro tongue tip spines across taxa. Key findings included variation in sensory pit numbers within the bill‐tip organs characteristic of Scolopacidae, and scanning electron microscopy (SEM) revealing micro tongue tip spines in several

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Rothe Time Discretization and Weak Solutions for a Cutoff Westervelt System

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACTWe study a fully implicit Rothe time discretization for a cutoff first‐order formulation of the Westervelt equation. The key ingredients are the enthalpy variable and the primitive mobility variable, which turn each nonlinear time step into a uniformly monotone elliptic problem and avoid higher‐order energy estimates and inverse inequalities ...

Advanced Electrospun Nanofiber Epidermal Electronics for Electrophysiological Monitoring: From Conformal Interfaces to Multimodal Closed‐Loop Systems

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Epidermal bioelectronics is a transformative technology for continuous health monitoring and human‐computer interaction. However, the mechanical and physiological mismatch at the skin–device interface limits its long‐term application. Electrospun nanofiber membranes (ENMs), with their unique three‐dimensional hierarchical porous network and ...

Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning

Journal of Field Robotics, Volume 43, Issue 6, Page 3617-3632, September 2026.
ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.
