Grouth and decay of shock waves in transversely isotropic rods

Le Matematiche, 1991
In this paper we study the propagation of shock waves in linear hyperelastic rods, transversely isotropic in the reference configuration.

Microstructural brain changes track cognitive decline in mild cognitive impairment

NeuroImage: Clinical, 2018
Improved characterization of the microstructural brain changes occurring in the early stages of Alzheimer's disease may permit more timely disease detection. This study examined how longitudinal change in brain microstructure relates to cognitive decline

Spectral energy dynamics in magnetohydrodynamic turbulence

, 2005
Spectral direct numerical simulations of incompressible MHD turbulence at a resolution of up to $1024^3$ collocation points are presented for a statistically isotropic system as well as for a setup with an imposed strong mean magnetic field.

Finite Element Model of the Effect of Optic Nerve Sheath Anisotropy on Ocular Loading During Horizontal Duction

Bioengineering
Previous models of extraocular mechanics have often assumed isotropic properties for ocular tissues, despite evidence indicating anisotropy in the optic nerve sheath (ONS).

Isotropic A-branes and the stability condition

, 2004
The existence of a new kind of branes for the open topological A-model is argued by using the generalized complex geometry of Hitchin and the SYZ picture of mirror symmetry.

On the existence of weakly nonlocal Rayleigh waves with impedance boundary condition

Archives of Mechanics
In this paper, the existence of Rayleigh waves propagating in weakly nonlocal incompressible isotropic elastic half-spaces subject to the tangential impedance boundary condition (TIBC) (at the surface of half-spaces, the tangential stress is proportional

Correlation between $T_c$ and anisotropic scattering in Tl$_2$Ba$_2$CuO$_{6+\delta}$

, 2007
Angle-dependent magnetoresistance measurements are used to determine the isotropic and anisotropic components of the transport scattering rate in overdoped Tl$_2$Ba$_2$CuO$_{6+\delta}$ for a range of $T_c$ values between 15K and 35K.

Electrical transport and pinning properties of Nb thin films patterned with focused ion beam-milled washboard nanostructures

New Journal of Physics, 2012
A careful analysis of the magneto-transport properties of epitaxial nanostructured Nb thin films in the normal and the mixed state is performed. The nanopatterns were prepared by focused ion beam (FIB) milling.

Contact interaction of a circular stamp with a layer under nonideal thermal contact.

Nauka ta progres transportu, 2011
Solution of the axis-symmetric contact task of thermo-elasticity of the hot cylinder circular punch stress on the elastic isotropic layer taking into account a non-ideal heat contact between punch and layer is built.

Theory and Modelling of Isotropic Turbulence: From Incompressible through Increasingly Compressible Flows

Atmosphere
Homogeneous isotropic turbulence (HIT) has been a useful theoretical concept for more than fifty years of theory, modelling, and calculations. Some exact results are revisited in incompressible HIT, with special emphasis on the 4/5 Kolmogorov law.
