Comprehensive review of serpentine flow fields for effective thermal management of proton exchange membrane fuel cell

open access: yesHeliyon
Besides the fact that the Proton Exchange Membrane Fuel Cells (PEMFCs) have become the industrial norm of today, the thermal management in PEMFCs is still challenging.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Behavior of Evacuees on Upper‐Level Walkways After Building Evacuation due to Fire: Design Implications From a Virtual Reality Study on Spatial Configuration, Density, and Influence of Other Evacuees' Route Choice

open access: yesJAPAN ARCHITECTURAL REVIEW
ABSTRACT In the central districts of Japanese cities, numerous large‐scale buildings are connected to upper‐level walkways, which serve as everyday circulation routes. However, the behavior of evacuees on these walkways during fires remains poorly understood.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Comparative Analysis of Buckling Load of Circular and Corrugated Tubes by Utilizing Key Performance Indicators

open access: yesInternational Journal of Applied Mechanics and Engineering, 2017
The performance of buckling load of tubular structures under quasi-static axial loading is quite appreciable, numerous tubes of various cross-section have been extensively investigated and corrugated sections have been designed to further improve the ...
