A Computational Model of Cn2 Profile Inversion for Atmospheric Laser Communication in the Vertical Path.

In this paper, an atmospheric structure constant Cn2 model is proposed for evaluating the channel turbulence degree of atmospheric laser communication. First, we derive a mathematical model for the correlation between the atmospheric coherence length r0, the isoplanatic angle θ0 and Cn2 using the Hufnagel-Valley (HV) turbulence model. Then, we calculate the seven parameters of the HV model with the actual measured r0 and θ0 data as input quantities, so as to draw the Cn2 profile and the θ0 profile.

Intervention Effects of Atorvastatin Combined with Saponins on Rats with Atherosclerosis Complicated with Hepatic Injury.

Background: Statins cannot be used for some active liver diseases, which limits its application to some extent. The combined use of statins with other drugs may be one of the ways to solve this dilemma.

Objective: This research aims to evaluate the effects of atorvastatin combined with saponins (PNS) on rats with atherosclerosis (AS) complicated with hepatic injury.
