Extended Strahler Ordering to Distinguish Mapped River Channels From Overland Flow Pathways and Consistently Compare Digital Networks

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Digital networks are virtual representations of freshwater systems that provide important inputs to, and mapping of, river classifications, simulation models, and quantitative data analyses for policy, planning, and management. Strahler order has often been used to characterize network configuration and as a proxy indicator of river channel ...

Size and shape variability in the skull of Myotis nigricans (Schinz, 1821) (Chiroptera: Vespertilionidae) from two geographic areas in Brazil

open access: yesBrazilian Journal of Biology
We present a quantitative analysis of sexual dimorphism and geographic variation in the skull of Myotis nigricans (Schinz, 1821) assessed by geometric morphometrics.

A UAV‐based deep learning pipeline for intertidal macrobenthos monitoring: Behavioral and age classification in Tachypleus tridentatus

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this

Evidence for Drop‐Like Nuclear Deformation in Sheared Endothelial Monolayers

open access: yesSmall, EarlyView.
Physiological shear stress smoothens endothelial monolayers by selectively eliminating less‐spread cells with tall, wrinkled nuclei. Nuclear volume and surface area remain constant, consistent with drop‐like deformation governed by geometric constraints.

Rapid Generation of Fusable Cell Beads for Multi‐Scale Human Living Materials Assembly

open access: yesSmall Methods, EarlyView.
Living beads are produced through the combination of metabolic glycoengineering, click chemistry, and superhydrophobic surfaces, to develop a spheroid alternative for bottom‐up tissue engineering and disease modeling. The living beads present a size independent of cell density and a rapid fabrication methodology, providing a platform that can fuse into

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

open access: yesSmall Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils
