In their seminal 1961 paper, Sudarshan, Mathews and Rau investigated properties of the dynamical A B maps acting on n-dimensional quantum systems. The nature in open system evolutions has attracted great deal attention later years. However, novel paper not received its due attention. this tutorial article, we review forms associated with dynamics finite dimensional particular, investigate a can...

A large number of different lesions and pathologies can affect the human digestive system, resulting in life-threatening situations. Early detection plays a relevant role successful treatment increase current survival rates to, e.g., colorectal cancer. The standard procedure enabling detection, endoscopic video analysis, generates quantities visual data that need to be carefully analyzed by an ...

It is well known that the cyanides and the nitriles when given to mammals leave the body in part as sulfocyanides. This suggests that they combine with the labile sulfur group of the albumins of the cell, and it was this fact which led us to undertake a study of the spontaneous oxidation of cystein. It is not necessary to recapitulate the evidence that the cyanides act on cell-respiration, sinc...

A previous model of hippocampal region function in classical conditioning is generalized to H. Eichenbaum, A. Fagan, P. Mathews, and N.J. Cohen's (1989) and H. Eichenbaum, A. Fagan, and N.J. Cohen's (1989) simultaneous odor discrimination studies in rats. The model assumes that the hippocampal region forms new stimulus representations that compress redundant information while differentiating pr...
