Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Numerical Analysis of Unsteady Natural Convection in a Circular Enclosure With an Internal Hot Channel: Combined Impact of Exothermic Reaction and Magnetohydrodynamics on Aluminum Oxide/Water

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Overheating, decreased performance, and system failures can result from ineffective thermal management in electronics, energy systems, and industrial processes where high‐efficiency heat exchange is essential. This study delves into the sophisticated heat transfer characteristics and flow dynamics of an aluminum oxide‐water nanofluid filled in

Feed‐Forward PID‐Based Cooperative Control Strategy for Air Mass Flow and Pressure in PEMFC Systems

open access: yesEnergy Science &Engineering, EarlyView.
This manuscript presents an 86 kW proton exchange membrane fuel cell (PEMFC) with a feed‐forward PID control strategy, tested in an engine environment. The air mass flow and pressure changes are analyzed across three stages: loading, de‐loading, and wide range of sudden load drop. Experimental results demonstrate the control strategy's effectiveness of
