pdf.[VN] J. von Neumann, Mathematische Grundlagen derQuantenmechanik, Springer, 1932. English translation:systems has opened a new field of mathematicalresearch.Starting in 1969, difficult experimental workbegan, using variants of Bell’s inequality, to test ifvery delicate predictions of quantum mechanicsare correct. Of course, quantum mechanics hasgiven superb explanations of all sorts of phenom-ena, but these experiments waterboard quantummechanics. Many experiments have been done; sofar there is no convincing evidence that quantummechanics is incorrect. In addition, experimentshave been done which suggest that influence fromone system to the other propagates enormouslyfaster than light. These experiments point towardinstantaneous transfer of information.Bell’s papers on quantum philosophy have beencollected in his book Speakable and Unspeakablein Quantum Mechanics [B]. The first paper [B66]discusses Gleason’s theorem and the second “Bell’sinequality”. The entire book is a pleasure to read.3

M arshall Hall Jr. (1910–1990) is deservedly well remembered for his role in constructing the simple group of order 604800 = 27 × 33 × 52 × 7 as well as numerous advances in combinatorics. A brief autobiography is on pages 367–374 of Duran, Askey, and Merzbach [5]. Hall notes that Howard Engstrom (1902–1962) gave him much help with his Ph.D. thesis at Yale in 1934–1936 and later urged him to wo...
متن کاملCorrelation between staining intensity of prostatic adenocarcinoma with P53 and Gleason's grading
Introduction: Prostatic adenocarcinoma is the most common malignancy of internal system and after lung cancer is the second cause of death in male. Genetic base of many neoplasms is related to suppressor tumor gene such as P53. Therefore, we aimed in this study, to assess the intensity of prostatic adenocarcinoma tissue staining with P53 staining method and its relationship with Gleason grade. ...

OBJECTIVE There is evidence showing that Gleason grading of prostatic adenocarcinoma is one of the most powerful predictors of biological behavior and one of the most influential factors used to determine treatment for prostate cancer. The aim of the current study was to compare the Gleason score for needle biopsy to the Gleason score for the correspondent surgical specimen, find any possible d...
