کشور ایران به دلیل موقعیت خاص جعرافیایی، در اکثر مناطق دارای اقلیم خشک و نیمه خشک است. به همین دلیل سیل یکی از بزرگترین معضلات و بلایای طبیعی در ایران است. بنابراین شناسایی اصولی مناطق دارای پتانسیل زیاد سیل خیزی در حوضه آبخیز از جمله کارهای بسیار مهم در کنترل سیل و کاهش خسارات ناشی از آن می باشد. در مطالعات انجام شده، مناطق دارای پتانسیل تولید سیل در داخل یک حوضه، تنها براساس دبی اوج زیرحوضه ه...

BACKGROUND The response of cells to TGFβ and EGF is mediated by a network of various intracellular regulators. The signaling crosstalk between different regulators is of key importance for tumorigenesis. The crosstalk may explain the modulation of cellular responses to the same regulator by another signaling molecule. As PKN1 - a serine/threonine kinase implicated in tumorigenesis - was identif...

Northern Vietnam is a region prone to heavy flash flooding events. These often have devastating effects on the environment, cause economic damage and, in the worst case scenario, cost human lives. As their frequency and severity are likely to increase in the future, procedures have to be established to cope with this threat. As the prediction of potential flash floods represents one crucial ele...

In this paper, we propose the HEC-PF scheme, an enhancement of our previous H-EC scheme for effective data forwarding in opportunistic networks. The enhanced scheme modifies the aggressive forwarding phase of the H-EC scheme by implementing a new Probabilistic Forwarding feature, which decides whether to forward a message to a newly encountered node based on the delivery probability. Using simu...

فرایند بارش- رواناب یک پدیده­ی کاملا" پیچیده و غیرخطی در آبشناسی و منابع آب می­باشد. در سالهای اخیر، شبکه‌های عصبی مصنوعی کاربرد گسترده­ای را در شبیه­سازی روابط غیرخطی و پیچیده مانند رابطه­ی بارش-رواناب پیدا کرده است. دراین تحقیق، به منظور شبیه­سازی آبنمود بارش-رواناب در حوضه­ی آبخیز معرف کسیلیان از روش شبکه­ی عصبی مصنوعی (با ساختار7-10-9) و نرم­افزار HEC-HMS استفاده گردید. به منظور آموزش بهتر ...

Towards the end of the 1980s, the issue of whether IS case research was rigorously conducted was first raised. Benbasat et al. (1987) and Lee (1989) formulated some key recommendations on how to conduct high quality case study research in our field. Since then, qualitative research, in general, and case research in particular, has evolved and grown considerably. For example, researchers from se...

Leukaemia inhibitory factor (LIF) is a pleiotropic cytokine which has been found to be expressed in the human endometrium and to play an important role in human reproduction. In the present study we investigated expression and regulation of the human LIF promoter in HEC-1B endometrial adenocarcinoma cells using a luciferase reporter plasmid bearing a 666 bp promoter fragment (h666LIF-Luc) in tr...

Initial Public Offerings (IPOs) in the United States have been mainly underwritten and sold using the bookbuilding method; a method inherently riddled with inefficiencies and information asymmetries. Consequently, IPOs in the U.S. (and other countries for that matter) have been persistently underpriced, at the expense of both the issuing firm and public investors. Alternative underwriting proce...

Male HBsAg carriers are more likely to develop HeC than female carriers (Anthony, 1984; Coursaget et aL., 1987), and there is some evidence that establishment of the carrier state prenataIIy or early in life is associated with a higher OR for HCC than establishment of a similar state in adulthood (Larouzé et al., 1976; London, 1981; Hsieh et al., 1992). Several factors other than HBV have been ...
