Time‐ and State‐Dependent Damage Accumulation Due to Aftershocks Under an M9.0 Megathrust Earthquake in the Cascadia Subduction Zone

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1157-1175, 25 April 2026.
ABSTRACT This study develops a comprehensive framework for assessing time and state‐dependent aftershock damage accumulation under an M9.0 megathrust interface earthquake in the Cascadia Subduction Zone (CSZ). The framework integrates aftershock probabilistic seismic hazard analysis (APSHA) and state‐dependent fragility analysis (SDFA) within a ...

Quercetin: A Light in the Fight Against MRSA

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Photoactivated quercetin reduces the bacterial load of MRSA in intradermally infected mice. The control of bacterial load is associated with a modulation of the inflammatory response in animals treated with aPDT. ABSTRACT Antimicrobial photodynamic therapy (aPDT) for treating methicillin‐resistant Staphylococcus aureus (MRSA) infections has gained ...
