Monotonicity and enclosure methods for the p-Laplace equation [PDF]
, 2017 We show that the convex hull of a monotone perturbation of a homogeneous background conductivity in the $p$-conductivity equation is determined by knowledge of the nonlinear Dirichlet-Neumann operator.

Simple holographic model of nonlinear conductivity [PDF]
Physical Review D, 2013 We present a simple analytic gravitational solution which describes the holographic dual of a (2+1)-dimensional conductor which goes beyond the usual linear response. In particular it includes Joule heating. We find that the nonlinear frequency-dependent conductivity is a constant. Surprisingly, the pressure remains isotropic. We also apply an electric

Maxwell-Drude-Bloch dissipative few-cycle optical solitons [PDF]
, 2010 We study the propagation of few-cycle pulses in two-component medium consisting of nonlinear amplifying and absorbing two-level centers embedded into a linear and conductive host material.

Nonlinear Conductance-Volume Relationship for Murine Conductance Catheter Measurement System [PDF]
IEEE Transactions on Biomedical Engineering, 2005 The conductance catheter system is a tool to determine instantaneous left ventricular volume in vivo by converting measured conductance to volume. The currently adopted conductance-to-volume conversion equation was proposed by Baan, and the accuracy of this equation is limited by the assumption of a linear conductance-volume relationship.

Nonlinear theory of resonant slow waves in anisotropic and dispersive plasmas [PDF]
, 2008 The solar corona is a typical example of a plasma with strongly anisotropic transport processes. The main dissipative mechanisms in the solar corona acting on slow magnetoacoustic waves are the anisotropic thermal conductivity and viscosity [Ballai et al.

Prediction of Thermo-Physical Properties of TiO2-Al2O3/Water Nanoparticles by Using Artificial Neural Network [PDF]
, 2020 In this paper, an artificial neural network is implemented for the sake of predicting the thermal conductivity ratio of TiO2-Al2O3/water nanofluid. TiO2-Al2O3/water in the role of an innovative type of nanofluid was synthesized by the sol–gel method. The

Investigation of electrical properties of ZnO@Ag/EPDM composites
AIP Advances, 2020 In this study, Ag conductive nanoparticles were successfully grown on ZnO semi-conductive nanosheets (abbreviated as ZnO@Ag) by combined sol–gel and liquid-phase chemical reduction methods.
