Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Improving ARTs: Microfluidics as a Tool for Sperm Selection
Andrology, EarlyView.ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.
