Local Pressure Response and Load Redistribution Characteristics of Bridge Pier Groups Under Debris-Flow Impact

Bridge piers in debris-flow channels are commonly assessed as isolated members, although an upstream pier may modify the loading applied to downstream piers. This study investigated local pressure responses in tandem twin-pier and equilateral triangular three-pier arrangements us...

Small extracellular vesicle-mediated epithelial–macrophage crosstalk contributes to macrophage dysfunction during PEDV infection

Abstract Mucosal immune defense depends on coordinated communication between epithelial and immune cells, yet pathogens can disrupt this crosstalk through diverse mechanisms. Here we show that porcine epidemic diarrhea virus (PEDV), an enteric alphacoronavirus, reshapes epithelia...
