Method on ionogram autoscaling based on IRI model

A new method approximation with BP network to obtain the profile of ionospheric electron density versus real height is described, how to resolve the group path integral equation with BP neural network is demonstrated, and the computation result with this method in resolving the ionogram correspondent with a parabolic model is givn in this paper.

A inverse algorithm of oblique ionogram and its stability;

According to the data from an oblique ionogram,parameters of the quasi-parabolic ionosphere model for the reflection point can be obtained based on genetic algorithm.

Objective To investigate the influence of citalopram on the fast response action potential,slow response action potential,in vitro electrocardiogram(ECG) and in vivo ECG of cardiac myocytes,and explore its mechanism of adverse cardiac effects.
