Low Mach Asymptotic Preserving Scheme for the Euler-Korteweg Model [PDF]

open access: yes, 2013
We present an all speed scheme for the Euler-Korteweg model. We study a semi-implicit time-discretisation which treats the terms, which are stiff for low Mach numbers, implicitly and thereby avoids a dependence of the timestep restriction on the Mach ...

Global nlassical solvability of a problem with nonlocal conditions for degenerate hyperbolic system of the first order equations [PDF]

open access: yesМатематичні Студії, 2012
Using the method of characteristics and the Banach fixed point theorem we established the existence and uniqueness of a global classical (smooth) solution to an initial-boundary value problem with nonlocal boundary conditions for a hyperbolic integro ...

Energy Decay for a Degenerate Hyperbolic Equation with a Dissipative Term

open access: yesPublications of the Research Institute for Mathematical Sciences, 1999
The goal of the paper is to study decay properties of the total energy of solutions to hyperbolic equations. In opposite to other papers which prefer to study wave equations with mass and dissipation, the author is interested in the Cauchy problem \[ u_{tt}- a(t)\Delta u+ 2b(t) u_t+ m^2u= 0\quad\text{in }\mathbb{R}^{n+1}_+, \] \[ u(0,x)= u_0(x),\quad ...

Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

open access: yesAdvanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

A 3D‐Printed Blister Test Platform for Quantifying Biointerface Adhesion Mechanisms

open access: yesAdvanced Materials Interfaces, EarlyView.
A 3D‐printed blister platform enables energy‐resolved characterization of soft hydrogel–rigid interfaces. Integrating precision pressure control with hyperelastic modeling directly quantifies adhesion energy (G) and R‐curve toughening. Results reveal that modulating hydrogel concentration and surface roughness drives a tunable transition from cohesive ...

Critical exponents for semilinear equations of mixed elliptic-hyperbolic and degenerate types

open access: yes, 2003
For semilinear Gellerstedt equations with Tricomi, Goursat or Dirichlet boundary conditions we prove Pohozaev type identities and derive non existence results that exploit an invariance of the linear part with respect to certain nonhomogeneous dilations.
