In the passed half century, great improvements have been achieved to make fiber-optic communication systems overweigh other traditional transmission systems such as coaxial systems in many applications. However, the physical features including optic fiber losses, group velocity dispersion (GVD) and nonlinear effects lead to significant system impairments in fiber-optic communications. The nonli...

Team Heterogeneity in Startups and its Development over Time We investigate the workforce heterogeneity of startups with respect to education, age and wages. Our explorative study uses data on the population of 1,614 Danish firms founded in 1998. We track these firms until 2001 which enables us to analyze changes in workforce composition over time. Such a dynamic analysis constitutes a hitherto...

OBJECTIVES To assess the value of external shielding of the testis during pelvic radiotherapy. MATERIAL AND METHODS Nineteen patients, receiving radiotherapy to the pelvis with the lower border of the field at the obturator foramen, were randomly selected. A 5 half value layer cerrobent shield was positioned at the inferior border of the field. The dose to the testis was measured with and wit...

This paper combines behavioral economics and social learning. Overconfident agents overweigh their private information relative to the public information revealed by the decisions of others. Therefore, when following a herd, they broadcast more of the information available to them. However, overconfidence trades the additional information revealed by overconfident decisions against more informa...

AIMS To review the epidemiological literature of urinary incontinence with respect to overweight and obesity as a risk factor, and how the findings eventually fulfill general criteria for being a causal factor for the condition. Likewise to review all interventional studies assessing the effect of weight reduction on incontinence. METHODS Systematic searches until June 2008 for publications o...

Higher density reduces distances, private car dependency and thus reduces greenhouse gas emissions (GHGs). As a result, increased density has been given a central role among urban development targets. However, it is not just travel behavior that changes along with density. Rather, the consumption patterns, or overall lifestyles, change along with changing urban structure, particularly with chan...

Much work is under way within the distributed computing community in order to assign a job to an appropriate resource discovered from a fully decentralized and heterogeneous infrastructure with reasonable cost, such as optimized job responsible time, executing price, etc. However, local resources of individual virtual organizations (VOs) are managed under independent policies and constraints, t...

Abstract The Meghna River, the largest and widest river in Bangladesh, is important for navigation, irrigation, fish spawning shelter, industrial usages, drinking water sources millions of people living nearby areas. present study illustrated seasonal variation some physicochemical parameters four heavy metals (Cr, As, Cd, Pb) distribution surface River estuary. It also evaluated human health r...

leptin is a hormone, which is secreted from fat tissue, has an important role to set cell metabolism and energy balance. the present study aims at the effect of twelve weeks high intensity interval training (hiit) on leptin level and obesity dependent factors among female students suffering overweight. in this semi-experimental study, twenty four students with bmi of 25-30 kg/m2 were selected p...

background: today prevalence of overweigh and obesity is increasing in most parts of the world. obesity plays an important role in creating health poverty in women and decreasing life span. the most common formula to assess physical health is body mass index (bmi). the present research was conducted to determine related factors (personal and reproductive characteristics) with women's bmi. metho...
