The tau neutrino is a neutral third generation lepton contained within the Standard Model Family Several experiments have been studying the properties of the tau neutrino nevertheless it has yet to be directly observed Several di erent methods that can allow one to study the mass of the tau neutrino are presented in this review The measurements of the lifetime and magnetic moment of the tau neu...

To decide whether a given sequence is “truely” random, or independent and identically distributed, we need to resort to nonparametric tests for randomness. Six tests: the ordinary run test, the sign test, the runs up and down test, the Mann-Kendall test, the Bartels’ rank test and the test based on entropy estimators are introduced in this report and their weaknesses are analyzed. Combining the...

The temperature data from 3 meteorological stations (Kashi, Ruoqiang, and Hotan) in the South of Tarim River Basin (STRB) during 1964-2011 were analyzed by Mann-Kendall test and correlation analysis. The results from Mann-Kendall test show that the surface temperature (ST), 850 hPa temperature (T850), and 700 hPa temperature (T700) exhibited upward trends, while 300 hPa temperature (T300) revea...

OBJECTIVES To estimate the agreement between the macular edema maps (MEMs) of the Retina Module of the Heidelberg Retina Tomograph II (Heidelberg Engineering, Heidelberg, Germany) and contact lens fundus biomicroscopy (FB) and to assess the influence of combining MEM data with the results of short-wavelength automated perimetry (SWAP) and fluorescein angiography (FA) on diagnostic test performa...

OBJECTIVE To analyze the effect of folic acid-fortified foods on the prevalence of neural tube defects in live newborns. METHODS Longitudinal study with newborns from the city of Recife, Northeastern Brazil, between 2000 and 2006. Data analyzed were obtained from the Sistema Nacional de Informações de Nascidos Vivos (National Information System on Live Births). Neural tube defects were define...

INTRODUCTION TRAIL protein may serve as an escape mechanism for cancer cells from the immune response. The aim of the study was to assess whether the presence of TRAIL protein correlates with unfavourable prognostic factors in breast carcinoma. MATERIAL AND METHODS The study group was composed of breast cancer patients treated surgically in the Department of Surgical Oncology, Medical Univers...

The expressions of MMP2, -7, -9, -13 and TIMP1, -2, -3 were examined in biopsies and cell lines of head and neck squamous cell carcinomas (HNSCC) to determine the association between the expression profile and TNM-staging of the primary. The expressions of MMP2, -7, -9, -13 and TIMP1, -2, -3 were analyzed in 30 HNSCC biopsies, 7 HNSCC cell lines and 1 keratinocyte cell line using RT-PCR. Negati...
