The Lopatinski determinant of small shocks may vanish [PDF]
arXiv, 2011 The Kreiss-Majda Lopatinski determinant encodes a uniform stability property of shock wave solutions to hyperbolic systems of conservation laws in several space variables. This note deals with the Lopatinski determinant for shock waves of sufficiently small amplitude. The determinant is known to be non-zero for so-called extreme shock waves, i.

Design of Double‐Sided Optical Coatings for Space Cooling Through Vertical Windows
Advanced Photonics Research, EarlyView.Dual‐sided radiative cooling glass (DSRCG) utilizes the optical properties of epsilon‐near‐zero materials and ITO to exhibit directional emission toward the outdoor space, facilitating the heat dissipation of the glass, while exhibiting low emission toward the enclosure.

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 491-501, December 2022., 2022 Flight and freezing are two vital defensive behaviors in the process of avoiding natural enemies in mice. We investigated the neural activity in dPAG nuclei of mice under two defensive behaviors, and found different coding features between flight and freezing behaviors. Abstract Background Flight and freezing are two vital defensive behaviors that mice

Advanced Sensor Research, EarlyView.The illustration showcases resonant optical microsensors for Doxorubicin (DXR) detection, using polystyrene sulfonate (PSS) as a synthetic receptor. PSS is deposited as a nanometer‐thick layer on fluorescent microparticles via layer‐by‐layer assembly. DXR‐PSS interaction is depicted, highlighting its effect on the sensor's resonant modes.

Cosmic ray acceleration at relativistic and ultrarelativistic shock waves [PDF]
arXiv, 2000 Using the Monte Carlo simulations we apply a method of discrete small amplitude particle momentum scattering to reproduce highly anisotropic conditions at relativistic shocks. We discusse acceleration times scales in relativistic shocks. Next, we describe newly found acceleration mechanism at ultrarelativistic shocks.

A High‐Performance Miniaturized Frequency Shift Detection System for QCM‐Based Gravimetric Sensing
Advanced Sensor Research, EarlyView.A miniaturized frequency shift detection system based on a phase‐locked loop (PLL) circuit is proposed for simplifying QCM measurement, possessing excellent performance of high sensitivity, resolution, linearity, and accuracy compared with a commercial frequency analyzer.

Advanced Theory and Simulations, EarlyView.Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

Asymptotic stability of shock waves and rarefaction waves under periodic perturbations for 1-D convex scalar conservation laws [PDF]
arXiv, 2018 In this paper we study large time behaviors toward shock waves and rarefaction waves under periodic perturbations for 1-D convex scalar conservation laws. The asymptotic stabilities and decay rates of shock waves and rarefaction waves under periodic perturbations are proved.
