Drag characteristics of micron-sized tungsten dust in high-Mach rarefied flow during in-vessel LOCA of fusion reactor with Maxwell slip/DSMC hybrid modeling

Nuclear Fusion
In a fusion reactor, an in-vessel loss of coolant accident (LOCA) involving the helium-cooled blanket will lead to the resuspension and migration of tritiated and micron-sized tungsten dust deposited at the bottom of the vacuum vessel under high-speed ...

The near-nucleus atmosphere of comet 67P/Churyumov – Gerasimenko at the moment of its rendezvous with the Rosetta space probe

St. Petersburg Polytechnical University Journal: Physics and Mathematics
The multicomponent atmosphere of a comet with a complex-shaped nucleus has been simulated. The geometry and integral parameters of the gas productivity of the nucleus correspond to the conditions of comet 67P/Churyumov – Gerasimenko at the moment of its ...

Slip conditions with wall catalysis and radiation for multicomponent, nonequilibrium gas flow [PDF]

The slip conditions for a multicomponent mixture with diffusion, wall-catalyzed atom recombination and thermal radiation are derived, and simplified expressions for engineering applications are presented. The gas mixture may be in chemical nonequilibrium

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Efficient prediction of aerodynamic forces in rarefied flow using convolutional neural network based multi-process method

Machine Learning: Science and Technology
The direct simulation Monte Carlo (DSMC) is a widely used approach for studying aerodynamics effects of rarefied flows, but it is highly time-consuming and may exhibit statistical fluctuations.

Comparison of CFD and DSMC Using Calibrated Transport Parameters [PDF]

Hypersonic re-entry flows span a wide range of length scales where regions of both rarefied and continuum flow exist. Traditional computational fluid dynamics (CFD) techniques do not provide an accurate solution for the rarefied regions of such mixed ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.
