In this paper we consider the p-coverage problem on the real line. We first give a detailed description of an algorithm to solve the coverage problem without the upper bound p on the number of open facilities. Then we analyze how the structure of the optimal solution changes if the setup costs of the facilities are all decreased by the same amount. This result is used to develop a parametric ap...

investments in the extension of health insurance coverage, the strengthening of public health services, as well as primary care and better hospitals, highlights the emerging role of healthcare as part of china’s new growth regime, based on an expansion of services, and redistributive policies. such investments, apart from their central role in terms of relief for low-income people, serve to reb...

Next-generation sequencing (NGS) technology is being applied to an increasing number of non-model species and has been used as the primary approach for accurate genotyping in genetic and evolutionary studies. However, inferring genotypes from sequencing data is challenging, particularly for organisms with a high degree of heterozygosity. This is because genotype calls from sequencing data are o...

The Coverage Control Technology is one of the basic technologies of wireless sensor network, and is mainly concerned about how to prolong the network lifetime on the basis of meeting users’ perception demand. Among this, in the study of area coverage, the set K-cover algorithm is broadly accepted because that it can prolong network lifetime rather well. However, maximum set covers problem is pr...

This review of the literature on disaster media coverage describes the events, samples, and forms of media coverage (television, newspapers, radio, internet) studied and examines the association between media consumption and psychological outcomes. A total of 36 studies representing both man-made and natural events met criteria for review in this analysis. Most studies examined disaster televis...

Under the background of full coverage of regulatory plan, the consistency research of land usage and transportation partition under a regulatory plan has been increasing, and there are also related researches covering their formulation, management and implementation aspects. This paper, from space perspective, analyzes the consistency of space division under full coverage of regulatory plan and...

Aluminas and their surface chemistry play a vital role in many areas of modern technology. The behavior of adsorbed water is particularly important and poorly understood. Simulations of hydrated alpha-alumina (0001) surfaces with ab initio molecular dynamics elucidate many aspects of this problem, especially the complex dynamics of water dissociation and related surface reactions. At low water ...
