36 month buy-and-hold returns are calculated for a recent sample of initial public offerings (IPOs) on UK stock markets in order to test the robustness of earlier results which suggest that IPOs deliver abnormally low long-run returns. A bootstrapped and skew-adjusted t statistic is employed. Overall, there is little evidence of significant abnormal long-run performance. Further tests reveal th...
Cryptococcosis is a worldwide disease caused by the etiological agent Cryptococcus neoformans. It affects mainly immunocompromised humans. It is relatively rare in animals only affecting those that have received prolonged antibiotic therapy. The propolis is a resin that can present several biological properties, including antibacterial, antifungal and antiviral activities. The standard strain C...
Static and discrete time pricing operators for two price economies are reviewed and then generalized to the continuous time setting of an underlying Hunt process. The continuous time operators define nonlinear partial integrodifferential equations that are solved numerically for the three valuations of bid, ask and expectation. The operators employ concave distortions by inducing a probability ...

حباب قیمتی پدیده ای است که در آن قیمت یک دارایی به طور فزاینده و با روندی غیر منطقی افزایش می یابد. نتایج تحقیقات نشان می دهد حباب ها ماهیتی غیر خطی دارد و معمولا روشهای معمول تعیین قیمت سهام از قبیل روش ارزش فعلی، روش ضریب قیمت به سود هر سهم و ... نمی تواند به خوبی ارزش سهم را تعیین نماید. در نگرش معمول و غیر سیستمی، رویکردی آبشاری یا خطی به پدیده ها مدنظر قرار می گیرد ولی در نگرش سیستمی که حا...

First, a shock to future generates significant decline credit spread indicators along with robust improvement supply indicators.

the objective of this study was to determine the effects of two different time of gnrh injection after artificial insemination (a.i) (d 6 and d 12) on reproductive performances of holstein cows during the warm season. cows randomly assigned to treatments 1) no gnrh injection (control, n = 300),2) gnrh injection at day 6 after a.i (g6, n=300) and 3) gnrh injection at day 12 after a.i (g12, n=30...
The unique ability of cell-penetrating peptides (CPPs), also known as protein transduction domains, to navigate across the nonpolar biological membrane has been under intense investigation. In vitro studies have shown that multiple mechanisms are available, with the precise details being dependent on the peptide and cell line studied. The several clearly demonstrated pathways include various fo...
