The uncapacitated facility location has always been an important problem due to its connection to operational research and infrastructure planning. Byrka obtained an algorithm that is parametrized by γ and proved that it is optimal when γ > 1.6774. He also proved that the algorithm achieved an approximation ratio of 1.50. A later work by Shi Li achieved an approximation factor of 1.488. In this...

Purpose: We have developed a systemic hepatic-damage index (SHI) based on serum total cholesterol (TC) and high density lipoprotein levels (HDL) and determined its prognostic significance in hepatocellular carcinoma (HCC) patients undergoing resection. Experimental Design: The SHI was analyzed in the training cohort of 188 HCC patients and in the validation cohort of 177 HCC patients. The syste...

. introduction the siberian high (sh) is a quasi-stationary and semi-permanent surface high pressure system residing over the eurasian continent during winter with its climatological–mean central pressure exceeding 1030 hpa. this most important atmospheric center of action controls the climate of a wide area of this continent. the sh forms generally in october mainly in response to strong radia...

Dynamin is a well-known regulator of synaptic endocytosis. Temperature-sensitive dynamin (shi(ts1)) mutations in Drosophila melanogaster or deletion of some of the mammalian Dynamins causes the accumulation of invaginated endocytic pits at synapses, sometimes also on bulk endosomes, indicating impaired membrane scission. However, complete loss of dynamin function has not been studied in neurons...

INTRODUCTION Migrants are a vulnerable population and could experience various challenges and barriers to accessing health insurance. Health insurance coverage protects migrants from financial loss related to illness and death. We assessed social health insurance (SHI) coverage and its financial protection effect among rural-to-urban internal migrants (IMs) in China. METHODS Data from the '20...

The current model of gibberellin (GA) signal transduction is based on a derepressible system and a number of candidate negative regulators have been identified in Arabidopsis. We previously have reported the identification of the Arabidopsis gene SHORT INTERNODES (SHI) that causes suppression of GA responses when constitutively activated. In this paper, we show by using reporter gene analysis t...

BACKGROUND China uses both social health insurance (SHI) programs and a medical financial assistance (MFA) program to protect the poor from illness-induced financial risks. The MFA provides a dual benefit package targeting low-income families: subsidizing these families' participation in SHI programs, and providing cash aid to protect them from catastrophic health expenditure (CHE). This study ...

The hierarchy of classical Chinese poetry has been broadly acknowledged by a number of studies in Chinese literature. However, quantitative investigations about the evolution of classical Chinese poetry are limited. The primary goal of this study is to provide quantitative evidence of the evolutionary linkages, with emphasis on word usage, among different period genres for classical Chinese poe...

BACKGROUND eHealth is developing rapidly and brings with it a promise to reduce social health inequalities (SHIs). Yet, it appears that it also has the potential to increase them. OBJECTIVES The general objective of this review was to set out how to ensure that eHealth contributes to reducing SHIs rather than exacerbating them. This review has three objectives: (1) identifying characteristics...
