The Quasi-Spectral Viscosity (QSV) method is a novel closure for high-order finite-difference discretization of the filtered compressible Navier-Stokes equations capable unifying dynamic sub-filter scale (SFS) modeling and shock capturing under single mathematical framework. Its innovation lies in introduction physical-space implementation spectral-like SFS dissipation term by leveraging residu...

Fear-conditioning experiments in the anxiety disorders focus almost exclusively on passive-emotional, Pavlovian conditioning, rather than active-behavioral, instrumental conditioning. Paradigms eliciting both types of conditioning are needed to study maladaptive, instrumental behaviors resulting from Pavlovian abnormalities found in clinical anxiety. One such Pavlovian abnormality is generaliza...

The physics of compressible vortex loops generated due to the rolling up of the shear layer upon the diffraction of a shock wave from a shock tube is far from being understood, especially when shock-vortex interactions are involved. This is mainly due to the lack of global quantitative data available which characterizes the flow. The present study involves the usage of the PIV technique to char...

Abstract When Mercury moves in its high-eccentricity orbit around the Sun, background solar wind conditions are significantly changed. We investigated effects of heliocentric distance and interplanetary magnetic field (IMF) orientation on shape location Mercury’s bow shock. fit empirical models to shock crossings obtained from MErcury Surface, Space ENvironment, GEochemistry, Ranging magnetomet...

Heat-shock proteins (HSPs) act like "chaperones", making sure that the cell's proteins are in the right shape and in the right place at the right time. Heat-shock protein glycoprotein 96 (gp96) is a member of the HSP90 protein family, which chaperones a number of molecules in protein folding and transportation. Heat-shock protein gp96 serves as a natural adjuvant for chaperoning antigenic pepti...

Collisionless shocks are some of the most efficient particle accelerators in heliospheric and astrophysical plasmas. Here we study quantify ion acceleration at Earth's bow shock with observations from NASA's Magnetospheric Multiscale (MMS) satellites a global hybrid-Vlasov simulation. From MMS observations, find that quasiparallel more accelerating ions. There, up to 15% available energy goes i...

The theory of shock acceleration predicts the maximum particle energy to be limited only by the acceleration time and the size (geometry) of the shock. This led to optimistic estimates for the galactic cosmic ray energy achievable in the SNR shocks. The estimates imply that the accelerated particles, while making no strong impact on the shock structure (test particle approach) are nevertheless ...

The theory of shock acceleration predicts the maximum particle energy to be limited only by the acceleration time and the size (geometry) of the shock. This led to optimistic estimates for the galactic cosmic-ray energy achievable in supernova remnant (SNR) shocks. The estimates imply that the accelerated particles, while making no strong impact on the shock structure (test-particle approach), ...

background and objectives: hydrocortisone is widely used in septic shock cases resistant to fluid and vasopressor therapy. it may result in increased blood pressure and survival. however the efficacy is no established among patients with severe burn and septic shock. accordingly it was assessed in this study. materials and methods: the patients older than 14 years of age with resistant septic s...

a b s t r a c t a 36-year-old male patient with posttraumatic cervical cord damage and resultant quadriparesis, demonstrated hypotension and periods of bradycardia. for most of his two-month stay in the intensive care unit (icu), he was dependent on dopamine support to maintain hemodynamic stability. keeping in mind evidence from the literature, that electrostimulation of acupoints neiguan (pc ...
