A Reduced‐Order Model for Performance‐Based Seismic Design of Suspended Piping Systems in Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Among non‐structural elements, suspended piping systems are critical to building functionality, enabling water circulation, waste disposal and fire suppression. Their seismic damage can lead to prolonged downtime, internal flooding and substantial direct and indirect economic losses.

Chiral perovskites for next‐generation chiral optoelectronics and spintronics

FlexMat, EarlyView.
Benefiting from structural inversion symmetry breaking and strong spin‐orbit coupling, chiral perovskites possess intriguing chiral optical and spin properties. We overview their advances and core applications in perovskite solar cells, circularly polarized light detectors and spin circularly polarized‐light‐emitting diodes, offering great potential ...

Chronic Prostatitis/Chronic Pelvic Pain Syndrome: Research Progress and Precision Diagnosis‐Therapy Under the Integrated Neuro–Immune–Metabolic–Microbiota Axis Framework

iMetaMed, EarlyView.
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is increasingly recognized as a systemic disorder rather than a purely local prostate disease. The diagram illustrates the transition from the traditional local prostate‐centered model to a multi‐axis systemic framework involving clinical heterogeneity, local prostatic inflammation, systemic ...
