Non-traumatic rhabdomyolysis is a rare complication of acute pancreatitis. One of the major risk factors of both acute pancreatitis and rhabdomyolysis is alcohol abuse. However, only a few studies have reported the prognosis and association of severe acute pancreatitis (SAP) and rhabdomyolysis in alcohol abuse patients. In the present study, we report two(More)
new blind estimation of MIMO channels using HGA was proposed for the frequency selective channel. By exploiting the output statistics, an objective function that coming from blind estimation of MIMO channels based on the subspace could be obtained. Then the fitness function based on the objective function is proposed for optimization by a hybrid genetic(More)
A modified MIMO channel estimation method based on superimposed training sequence was proposed for the frequency selective channel. By exploiting the uncorrelation between the training and information sequences, accurate primary channel parameters could be obtained without loss of bandwidth, and using weight factor averaged neighboring channel parameters.(More)
This article studies the classical MDS and dwMDS location algorithm.On this basis, steepest descent algorithm is introduced to replace SMACOF algorithm as optimization objective function. The results show that the steepest descent method as the optimization objective function is simple and easy to implement. Compared with the dwMDS method based on SMACOF(More)
