Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

Liver International Communications, Volume 7, Issue 2, June 2026.ABSTRACT Background and Aim The Fatty Liver Index (FLI) is a proxy for hepatic steatosis, but its performance against magnetic resonance imaging (MRI) is unknown in African populations. We evaluated the discriminatory performance of the FLI for detecting hepatic steatosis in European men (EM) and West African men (WAM) in the UK, and Black South ...

Data-driven nonlinear constitutive relations for rarefied flow computations
Advances in Aerodynamics, 2021 To overcome the defects of traditional rarefied numerical methods such as the Direct Simulation Monte Carlo (DSMC) method and unified Boltzmann equation schemes and extend the covering range of macroscopic equations in high Knudsen number flows, data ...

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.ABSTRACT Chemical vapor infiltration (CVI) is widely used to manufacture ceramic matrix composites, but deposition non‐uniformity and premature pore closure still limit processing time and cost. CVI operates at low pressures and in microscale pores, where non‐equilibrium gas transport develops, making common continuum assumptions unreliable.

Gas Flow and Heat Transfer in an Enclosure Induced by a Sinusoidal Temperature
Journal of Applied Fluid Mechanics, 2019 The heat transfer and flow characteristics of rarefied gas confined within a square cavity are investigated. The cavity upper-wall is subjected to a symmetrical sinusoidal temperature with respect to its midline.

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1026-1044, June 2026.Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

Multiscale simulation of rarefied gas dynamics via direct intermittent GSIS-DSMC coupling
Advances in AerodynamicsThe general synthetic iterative scheme (GSIS) has proven its efficacy in modeling rarefied gas dynamics, where the steady-state solutions are obtained after dozens of iterations of the Boltzmann equation, with minimal numerical dissipation even using ...
