background: liver cirrhosis was one of the most important liver diseases. other chronic liver diseases could be lead to liver cirrhosis. liver cirrhosis could be lead one kind of liver cancers named hepatocellular carcinoma. cirrhosis in the early stages just by laboratory and imaging testes could be diagnosed. in this study cirrhotic patients were classified based on laboratory symptoms. for t...

Nowadays, factors such as economic globalization and creation of global markets, rapid changes of technologies, become-knowledgeable organizations, expansion of e-commerce, rapid and easy access of the consumer to goods and services, and change of their social requirements have caused a severe competition among businesses followed by a stress on these organizations` personnel. Thus, aside the o...

Optimising the approximation of Average Precision (AP) has been widely studied for image retrieval. Limited by definition AP, such methods consider both negative and positive instances ranking before each instance. However, we claim that only penalizing ones is enough, because loss comes from these instances. To this end, propose a novel loss, namely Penalizing Negative Positive (PNP), which ca...

between 1970 and 1990, the number of people in the United States living in high-poverty census tracts (with poverty rates of 40 percent or more) nearly doubled, from 4.1 to 8.0 million. Children who live in poor urban neighborhoods are disproportionately likely to be members of racial and ethnic minority groups and are also at greater risk for school failure. For example, only 11 percent of fou...

When the degree of intersections A∩B of events A,B is unknown arises a problem: how to evaluate the probability P(A ∩ B) and P(A ∩B) from P(A) and P(B). To treat related problems two models of valuation: interval and paired probabilities are proposed. It is shown that the valuation corresponding to the set operations ∩ (intersection), ∪ (union) and ∼ (complement) can be described by the truth f...

An efficient chiral squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to 3-nitro-2H-chromenes for the synthesis of chiral heterocyclic systems containing both chroman and pyrazolone derivatives has been developed. This reaction afforded the desired products in high to excellent yields (up to 98%) with high enantioselectivities (up to 96%) and excellent diastereoselectiv...

This paper identifies the prevalence and predictors of obesity among California's American Indian adults. A cross-sectional study was conducted at 13 rural sites. Indian healthcare clinics served as the sampling frame and were selected because of their proximity and access to the target population. Four-hundred and fifty adult American Indians participated; 74 percent were female and 26 percent...
