Connected Target Coverage (CTC) problem [8], covering given targets fully with the deployed sensors and also guaranteeing connectivity to a sink node, is a challenging scheduling problem. In this paper, unlike the existing heuristic algorithms, we adopt the probabilistic coverage model to solve the problem and develop a heuristic algorithm called CWGC-PM(More)
By using improved methods for in situ hybridization to detect expression of androgen receptor (AR) mRNA, the distribution of expression was mapped in the adult male zebra finch brain. In the neural song circuit, robust expression was found in area X of the lobus parolfactorius (LPO) as well as in other song regions previously reported. Expression was also(More)
BACKGROUND Despite virtually identical DNA sequences between the sexes, sexual dimorphism is a widespread phenomenon in nature. To a large extent the systematic differences between the sexes must therefore arise from processes involving gene regulation. In accordance, sexual dimorphism in gene expression is common and extensive. Genes with sexually(More)
—Efficient deployment of sensors is an important issue in wireless sensor networks. If we deploy sensors randomly by our hands or carriers only, some unlucky places are not covered forever. In this paper, we propose distributed self-deployment schemes of mobile sensors. At first, sensors are deployed randomly. They then calculate the next positions locally(More)
A critical issue in wireless sensor networks is an energy-efficiency since the sensor batteries have limited energy power and, in most cases, are not rechargeable. The most practical manner relate to this issue is to use a node wake-up scheduling protocol that some sensor nodes stay active to provide sensing service, while the others are inactive for(More)
BACKGROUND In this study we compared the surgical management of ischemic mitral regurgitation (IMR) by revascularization alone and by revascularization combined with mitral valve repair. METHODS We studied 355 patients who underwent revascularization alone (n = 168) or revascularization combined with mitral valve repair (n = 187) for IMR from March 1994(More)
The brains of males and females differ, not only in regions specialized for reproduction, but also in other regions (controlling cognition, for example) where sex differences are not necessarily expected. Moreover, males and females are differentially susceptible to neurological and psychiatric disease. What are the origins of these sex differences? Two(More)
Mutations in the gene encoding methyl CpG binding protein 2 (MeCP2) are the primary cause of the neurodevelopmental disorder Rett syndrome (RTT). Mecp2-deficient mice develop a neurological phenotype that recapitulates many of the symptoms of RTT, including postnatal onset of the neurological deficits. MeCP2 has two isoforms, MeCP2e1 and MeCP2e2, with(More)
We compared global patterns of gene expression between two bird species, the chicken and zebra finch, with regard to sex bias of autosomal versus Z chromosome genes, dosage compensation, and evolution of sex bias. Both species appear to lack a Z chromosome-wide mechanism of dosage compensation, because both have a similar pattern of significantly higher(More)
Dissolved organic matter (DOM) in effluents from sewage and human-wastes treatment plants (STPEs and HWTPEs) was fractionated using resin adsorbents into six classes: aquatic humic substances (AHS), hydrophobic bases (HoB), hydrophobic neutrals (HoN), hydrophilic acids (HiA), hydrophilic bases (HiB), and hydrophilic neutrals (HiN). DOM-fraction distribution(More)
