Inspired by the computational simplicity and numerical stability of QR decomposition, a nonparametric method for estimating the number of signals without eigendecomposition (MENSE) is proposed for the coherent narrowband signals impinging on a uniform linear array (ULA). By exploiting the array geometry and its shift invariance property to decorrelate the coherency of signals through subarray a...
Despite abundant research on the distribution of glottal stops and glottalization in English and other languages, it is still unclear which factors matter most in predicting where glottal stops occur. In this study, logistic mixed-effects regression modeling is used to predict the occurrence of word-initial full glottal stops vs. no voicing irregularity. The results indicate that prominence and...
Background and aim: Hirsutism is a common clinical problem among women; however estimates regarding its prevalence in our population are limited. The objective of this study was to estimate the frequency and features of hirsutism in yound women in Iran.Materials and Methods: This descriptive-cross sectional study was performed on 800 female (18-25 years) medical student...
htp:// D ow nladed from The tumor suppressor PTEN restrains cell migration and invasion by a mechanism that is independent of inhibition of the PI3K pathway and decreased activation of the kinase AKT. PREX2, a widely distributed GEF that activates the GTPase RAC1, binds to and inhibits PTEN. We used mouse embryonic fibroblasts and breast cancer cell lines to show that PTEN suppresses cell migra...
The El Niño/Southern Oscillation (ENSO) phenomenon is the dominant climatic fluctuation on interannual time scales. It is an irregular oscillation with a distinctive broadband spectrum. In this article, we discuss recent theories that seek to explain this irregularity. Particular attention is paid to explanations that involve the stochastic forcing of the slow ocean modes by fast atmospheric tr...
BACKGROUND Hirsutism is one of the most important diseases that lead women to refer to dermatology clinic. Hyperprolactinemia is one of the causes of hirsutism. The aim of this study was to determine prolactin (PRL) levels in hirsute women. MATERIALS AND METHODS In this cross-sectional study, hirsute patients were evaluated. For all of the patients, 2 or 3 days after mense starting, hormone l...
