Stability of initial-boundary value problem for quasilinear viscoelastic equations
We investigate the stability of the initial-boundary value problem for the quasilinear viscoelastic equation $$\displaylines{ |u_t|^{\rho}u_{tt}-\Delta u_{tt}-\Delta u+\int_0^tg(t-s)\Delta u(s)ds=0, \quad \text{in }\Omega\times(0,+\infty),\cr u=0 ...

Decay results for viscoelastic diffusion equations in absence of instantaneous elasticity
We study the diffusion equation in the absence of instantaneous elasticity $$ u_t-int_0^{t}g(t-au )Delta u(au ),dau =0,quad (x,t)in Omega imes (0,+infty ), $$ where $Omega subset mathbb{R}^n$, subjected to nonlinear boundary conditions.

Spin relaxation rate for heavy quarks in weakly coupled QCD plasma
We compute the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma to leading-log order in the coupling constant g. The spin relaxation rate Γ s in spin hydrodynamics is shown to be Γ s ~ g 4 log(1/g)T(T/M)2 in the heavy ...

Investigation of NMR relaxation data using dipole correlation function
In this work, the theories of the relaxation mechanism leading to the dipole-correlation function, playing an important role in the analysis of the spin-lattice and spin-spin relaxation times in magnetic rezonance, are investigated.

The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Rate of decay for solutions of viscoelastic evolution equations
In this article we consider a Cauchy problem of a nonlinear viscoelastic equation of order four. Under suitable conditions on the initial data and the relaxation function, we prove polynomial and logarithmic decay of solutions.

Stress relaxation models with polyconvex entropy in Lagrangean and Eulerian coordinates
The embedding of the equations of polyconvex elastodynamics to an augmented symmetric hyperbolic system provides in conjunction with the relative entropy method a robust stability framework for approximate solutions \cite{LT06}.

Relaxation of convex functionals: the gap problem
It is shown that the relaxed energy \mathcal{F}\left(u,A\right): = \inf \Big\{ \lim\!\! \inf_{n\rightarrow + \infty }\!\int \limits_{A}\! f(x,\nabla u_{n})dx:\{u_{n}\} \subset W_{\text{loc}}^{1,\beta }(A;\mathbb{R}^{d}),\, u_{n}\!\rightarrow\! u \text{ in }L^{1}(A;\mathbb{R}^{d}) \Big\},

This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the
