Study of a New Asymptotic Preserving Scheme for the Euler System in the Low Mach Number Limit

SIAM Journal on Scientific Computing, 2017
This article deals with the discretization of the compressible Euler system for all Mach numbers regimes. For highly subsonic flows, since acoustic waves are very fast compared to the velocity of the fluid, the gas can be considered as incompressible ...

A Multi-Mode Dynamic Fusion Mach Number Prediction Framework

Aerospace
The precise control of Mach numbers in supersonic and hypersonic compressor wind tunnel systems is a critical challenge in aerodynamic research. Although existing studies have improved prediction accuracy to some extent through machine learning methods ...

The rs10191329 Risk Allele Is Associated With Pronounced Retinal Layer Atrophy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate whether the rs10191329 risk allele in the DYSF–ZNF638 locus, which is implicated in central nervous system resilience rather than immune‐mediated pathology, is associated with retinal layer thinning, a biomarker of neuroaxonal damage in relapsing multiple sclerosis (RMS). Methods From a prospective observational study,

Monolithic Terahertz Topological Mach‐Zehnder Interferometer

Advanced Materials, EarlyView.
A monolithic topological Mach‐Zehnder interferometer (MZI) is presented, integrating the splitter, combiner, and waveguide arms on a single chip. The interferometric fringes exhibiting high on‐off contrast with extinction ratios over 20 dB are achieved by utilizing tailored unit cells that facilitate interface‐dependent out‐of‐plane radiation losses ...

A Low Mach Number Model for Moist Atmospheric Flows

, 2015
We introduce a low Mach number model for moist atmospheric flows that accurately incorporates reversible moist processes in flows whose features of interest occur on advective rather than acoustic time scales. Total water is used as a prognostic variable,
