The initiation mechanism of gravel-type debris flow based on laboratory simulation experiments

Scientific Reports
Debris flow is a geological process primarily triggered by factors such as rainfall or earthquakes, characterized by strong abruptness and significant destructive force. It poses a severe threat to human life and property.

In vitro generation of regulatory T cells: A challenging tool for studying immune aging in humans

FEBS Open Bio, EarlyView.
In vitro induction of human regulatory T cells using standard protocols generates suppressive, Foxp3‐expressing CD4+ T cells independently of TGF‐β supplementation and donor age. Regulatory T (Treg) cells play a key role in immune tolerance and homeostasis.

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Water flux and sediment transport within a forested landscape: the role of connectivity, subsurface flow, and slope length scale on transport mechanism

, 2013
The connectivity and upscaling of overland runoff and sediment transport are important issues in hillslope hydrology to identify water flux and sediment transport within landscape.

Determinants of undergraduate bioscience engagement: Validating attendance barriers and classroom spatial behaviour across institutions

FEBS Open Bio, EarlyView.
Student engagement extends beyond simple attendance. Across 891 bioscience students from three universities, attendance behaviour was associated mainly with structural influences, whereas classroom spatial behaviour reflected affective and sensory factors.

Experimental investigation of flow in a vortex drop shaft with an Archimedean spiral inlet

Scientific Reports
Vortex drop shafts are an effective solution for conveying flow in steep elevation drops. This study presents an experimental investigation of a new vortex drop shaft inlet design, the Archimedean spiral inlet with the aim of facilitating construction is

Numerical Simulation of Hydraulic Response of Immersed Slope Based on Dual-permeability Model of Unsaturated Macropore Flow

工程科学与技术, 2020
Restricted by terrain, a large number of roads and railways often appear along the reservoir line and along the river line, and water level changes are an important factor causing landslides on the banks.

Ultrafast visual detection of Streptococcus suis via HtpsC‐targeted LAMP–CRISPR–Cas12a coupled with lateral flow immunochromatography

FEBS Open Bio, EarlyView.
A rapid visual test combines DNA amplification, CRISPR–based target verification, and a lateral flow strip to detect Streptococcus suis. The assay gives results in about 45 min, reduces false‐positive interpretation, and does not require fluorescence equipment.

Spatiotemporal numerical modeling of wave overtopping flow over dike crests and landward slopes

Applied Ocean Research
Wave overtopping can cause severe erosion on the crest and landward slope of a dike. Accurate erosion prediction requires resolving the spatiotemporal evolution of overtopping flow, which remains insufficiently understood.
