15 صفحه اولResonances for Steplike Potentials: Forward and Inverse Results
We consider resonances associated to the one dimensional Schrödinger operator − d 2 dx2 + V (x), where V (x) = V+ if x > xM and V (x) = V− if x < −xM , with V+ = V−. We obtain asymptotics of the resonance-counting function for several regions. Moreover, we show that in several situations, the resonances, V+, and V− determine V uniquely up to translation.
متن کاملComputational Modeling of Single Neuron Extracellular Electric Potentials and Network Local Field Potentials using LFPsim
Local Field Potentials (LFPs) are population signals generated by complex spatiotemporal interaction of current sources and dipoles. Mathematical computations of LFPs allow the study of circuit functions and dysfunctions via simulations. This paper introduces LFPsim, a NEURON-based tool for computing population LFP activity and single neuron extracellular potentials. LFPsim was developed to be ...
متن کاملModeling extracellular field potentials and the frequency-filtering properties of extracellular space.
Extracellular local field potentials are usually modeled as arising from a set of current sources embedded in a homogeneous extracellular medium. Although this formalism can successfully model several properties of extracellular local field potentials, it does not account for their frequency-dependent attenuation with distance, a property essential to correctly model extracellular spikes. Here ...
متن کامل2D DC resistivity forward modeling based on the integral equation method and a comparison with the RES2DMOD results
A 2D forward modeling code for DC resistivity is developed based on the integral equation (IE) method. Here, a linear relation between model parameters and apparent resistivity values is proposed, although the resistivity modeling is generally a nonlinear problem. Two synthetic cases are considered for the numerical calculations and the results derived from IE code are compared with the RES2DMO...
