Using femtosecond time- and angle-resolved photoemission spectroscopy, we investigated the nonequilibrium dynamics of the topological insulator Bi2Se3. We studied p-type Bi2Se3, in which the metallic Dirac surface state and bulk conduction bands are unoccupied. Optical excitation leads to a metastable population at the bulk conduction band edge, which feeds a nonequilibrium population of the su...

Objective—Disruption of fascicular tracts that connect Wernicke’s to Broca’s areas is the classic mechanism of conduction aphasia. Later work has emphasised cortical mechanisms. Methods—To determine the distribution of language on dominant cortex, electrical cortical stimulation was performed using implanted subdural electrodes during brain mapping before epilepsy surgery. Results—A transient, ...

Lie symmetry method is applied to find analytic solutions of initial-boundaryvalue problems of transient conduction in semi-infinite solid with constant surface temperature or constant heat flux condition. The solutions are obtained in a manner highlighting the systematic procedure of extending the symmetry method for a PDE to investigate BVPs of the PDE. A comparative analysis of numerical and...

Uniform temperature control of heating plate with a wide thermal conduction area is required in many industrial application fields. In this paper, a novel approach for uniform heating based on the physical property of thermal conduction is proposed. The main idea of the proposed scheme is to control the average and gradient temperatures between arbitrary points whereas in conventional way direc...

This paper presents the solution of coupled radiative transfer equation with heat conduction equation in complex three-dimensional geometries. Due to very different time scales for both physics, the radiative problem is considered steady-state but solved at each time iteration of the transient conduction problem. The discrete ordinate method along with the decentered streamline-upwind Petrov-Ga...

BACKGROUND Conduction defects complicating acute myocardial infarction (MI) are frequent and associated with increased mortality and complications. Common conduction defects after acute MI are atrioventricular nodal blocks (1st, 2nd and 3rd degree) and intraventricular conduction defects (right or left bundle branch blocks and hemiblocks). In myocardial infarction occlusion of coronary arteries...

Non-Fourier heat conduction model with dual phase lag wave-diffusion model was analyzed by using well-conditioned asymptotic wave evaluation (WCAWE) and finite element method (FEM). The non-Fourier heat conduction has been investigated where the maximum likelihood (ML) and Tikhonov regularization technique were used successfully to predict the accurate and stable temperature responses without t...

Convection, conduction, and thermal radiation are the three mechanisms of heat transfer in nature. The lattice Boltzmann model (LBM) has already achieved great success dealing with convection conduction problems. However, mature LBM for radiative (RHT) is still relatively lacking. Here we propose a mesoscopic RHT graded-index media, which enables simple efficient solution both transient steady-...

INTRODUCTION AND OBJECTIVES Minimising false positives rates is an important goal of universal newborn hearing screening programmes. An adequate way for reaching that goal could be differentiating between transient conductive hearing losses (false positives) and permanent sensorineural hearing impairments (true positives) by means of a methodology that studies electrophysiological responses obt...
