We consider the classical Cauchy problem for a system of equations describing 3D arbitrary electrostatic oscillations cold plasma and introduce an iteration procedure that allows estimating blow-up time from below. This is constructive provided one succeed to obtain two-sided estimate additional quantity depending on solution. show this possible in case two dimensions, as well solutions with ze...

Objective This study aims to offer a new approach for quantifying severity of traditional Chinese medicine pattern with multidimensional analysis methods. Methods A scale and theoretical models were constructed based on the definition of liver stagnation spleen deficiency pattern. Clinical data of 344 IBS-D patients from a cross-sectional study was used for feature validation of the model. Co...
