Although conduction velocity in cardiac tissue is dependent on fiber orientation, the influence of commonly used antiarrhythmic agents on conduction longitudinal and transverse to such fibers is unknown. We evaluated the effects of procainamide on conduction velocity and intracel
Molecular Dynamics Prediction of the Thermal Conductivity of Si/ge Superlattices
Molecular dynamics simulations and the non-equilibrium direct method are used to predict the thermal conductivity of a Si/Ge superlattice modeled by the Stillinger-Weber potential at a temperature of 300 K. We focus on the methodology of making the thermal conductivity prediction
Conductance of a Finite Quantum Wire Connected to Reservoirs
We study a finite quantum wire connected to external leads, and show that the conductance of the system significantly depends upon the length of the quantum wire and the position of the impurity in it. For a very long quantum wire and the impurity far away from its two ends, the
Effect of substrate on thermal conductivity of single-walled carbon nanotubes
We analyze numerically the thermal conductivity of single-walled carbon nanotubes placed on a flat rigid substrate. We demonstrate that the character of thermal conductivity depends crucially on the interaction between the nanotube and the substrate. In particular, we reveal that
Crystalline polymers with exceptionally low thermal conductivity studied using molecular dynamics
Semi-crystalline polymers have been shown to have greatly increased thermal conductivity compared to amorphous bulk polymers due to effective heat conduction along the covalent bonds of the backbone. However, the mechanisms governing the intrinsic thermal conductivity of polymers
Single-molecule junction conductance through diaminoacenes.
The study of electron transport through single molecules is essential to the development of molecular electronics. Indeed, trends in electronic conductance through organic nanowires have emerged with the increasing reliability of electron transport measurements at the single-mole
LABORATORY INVESTIGATION ELECTROPHYSIOLOGY Frequency-dependent effects of calcium antagonists on atrioventricular conduction and refractoriness: demonstration and characterization in anesthetized dogs
Calcium-channel blockers are known to affect slow inward current in a frequencydependent fashion. The purpose of these experiments was to study use-dependent effects of verapamil, diltiazem, and nifedipine on atrioventricular conduction in vivo. Loading and maintenance infusion t
Superdiffusive Conduction: AC Conductivity with Correlated Noise
We present evidence of the existence of a superdiffusive regime in systems with correlated disorder for which localization is suppressed. An expression for anomalous electrical conductivity at low frequencies is found by using a generalized Langevin equation whose memory function
On the Statistical Significance of Conductance Quantization
Recent experiments on atomic-scale metallic contacts have shown that the quantization of the conductance appears clearly only after the average of the experimental results. Motivated by these results we have analyzed a simplified model system in which a narrow neck is randomly co
INSTITUT FÜR WISSENSCHAFTLICHES RECHNEN UND MATHEMATISCHE MODELLBILDUNG Resolution-Controlled Conductivity Discretization in Electrical Impedance Tomography
This work contributes to the numerical solution of the inverse problem of determining an isotropic conductivity from boundary measurements, known as Electrical Impedance Tomography. To this end, we first investigate the imaging resolution of the Complete Electrode Model in a circ
