ABSTRACT
The cross section of the process e^{+}e^{-}âπ^{+}π^{-} has been measured in the center-of-mass energy range from 0.32 to 1.2 GeV with the CMD-3 detector at the electron-positron collider VEPP-2000. The measurement is based on an integrated luminosity of about 88 pb^{-1}, of which 62 pb^{-1} represent a complete dataset collected by CMD-3 at center-of-mass energies below 1 GeV. In the dominant region near the ρ resonance a systematic uncertainty of 0.7% was achieved. The implications of the presented results for the evaluation of the hadronic contribution to the anomalous magnetic moment of the muon are discussed.
ABSTRACT
The authors picked out 200 case records of the patients with acute pancreatitis using a method of random sample. By means of the method of step-by-step discriminant analysis, the severity of the course of the disease was prognosticated. The age of a patient, duration of the disease, body temperature, leukocytic count and glucose level in the blood, amylase activity in the urine, presence of another pathology were analysed. The solving rule permitting to prognosticate an outcome of the disease with a high degree of probability was obtained. A variable directly dependent on the severity of a course of the disease--"degree of the severity of acute pancreatitis" was established.
