Linear and Weakly Nonlinear Triple Diffusive Convection in a Couple Stress Fluid Layer [PDF]
, 2014 The effect of couple stresses on linear and weakly nonlinear stability of a triply diffusive fluid layer is investigated. Several departures not observed either in singly or doubly diffusive couple stress fluid layer have been identified while analyzing ...

Couple stress fluid past a sphere embedded in a porous medium [PDF]
Archive of Mechanical Engineering, 2021 This paper concerns the analytical investigation of the axisymmetric and steady flow of incompressible couple stress fluid through a rigid sphere embedded in a porous medium. In the porous region, the flow field is governed by Brinkman's equation.

Mechanical and microscopic properties of the reversible plastic regime in a 2D jammed material [PDF]
, 2013 At the microscopic level, plastic flow of a jammed, disordered material consists of a series of particle rearrangements that cannot be reversed by subsequent deformation. An infinitesimal deformation of the same material has no rearrangements.

Holographic currents in first order Gravity and finite Fefferman-Graham expansions [PDF]
, 2006 We study the holographic currents associated to Chern-Simons theories. We start with an example in three dimensions and find the holographic representations of vector and chiral currents reproducing the correct expression for the chiral anomaly.
