On the propagation of a normal shock wave through a layer of incompressible porous material [PDF]
A novel numerical formulation of the two-phase macroscopic balance equations governing the flow field in incompressible porous media is presented. The numerical model makes use of the Weighted Average Flux (WAF) method and Total Variation Diminishing ...

ABSTRACT Diabetic wounds are characterized by persistent inflammation and impaired immune resolution, yet the therapeutic translation of single‐cell atlases into rational immunomodulatory strategies remains limited. Here, integration of diabetic‐wound single‐cell transcriptomic datasets identifies a neutrophil subpopulation enriched in cluster of ...

Riemann problem for a two-dimensional quasilinear hyperbolic system
This article concerns the study of the Riemann problem for a two-dimensional non-strictly hyperbolic system of conservation laws. The initial data are three constant states separated by three lines and are chosen so that one of the three interfaces ...

Mechanism of Direct Acoustic Construction and Gradient Properties Tuning
Directed acoustic construction enables omnidirectional gradient tuning of fingerprint‐inspired microstructures. By investigating the DAC mechanisms, diamond particles are found to enhance acoustic physical, mechanical, and chemical effects, promoting acoustic curing and broadening the range of gradient property tuning.

One-dimensional nonlinear chromatography system and delta-shock waves [PDF]
The author considers the Riemann problem for the following nonlinear chromatography system \[ \partial_t u+\partial_x\bigl(u/(1-u+v)\bigr)= \partial_t v+\partial_x\bigl(v/(1-u+v)\bigr)=0 \] and proves existence of a weak solution, which may contain delta-shock waves in the both components \(u,v\).

DNS of the interaction between a shock wave and a turbulent shear flow: some effects of anisotropy [PDF]
Direct numerical simulation is used to study the interaction of a Mach 1.5 shock wave and various types of anisotropic turbulent flows. We compare the interaction of isotropic, axisymmetric and sheared turbulences (sometimes combined), with a specific ...

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...

Mechanically‐Gated Stochastic Resonance for All‐Optical Acoustic Sensing in Noisy Environments
A mechanically‐gated stochastic resonance (MGSR) sensing system is demonstrated, wherein stochastic resonance is enabled by an all‐optical bistable fiber Bragg grating feedback loop and gated by mechanical resonance. Under ambient noise, the system generates bistable outputs satisfying the Kramers escape‐rate condition, yielding signal‐to‐noise ratio ...
