We construct an efficient 3-source extractor that requires one of the sources to be significantly shorter than the min-entropy of the other two sources. Our extractors work even when the longer, n-bit sources have min-entropy n and the shorter source has min-entropy log n. Previous constructions for independent sources with min-entropy n required Θ(1/γ) sources [Rao06]. Our construction relies ...

This paper proposes an evolvable hardware system with capability of evolution under uneven image environment, which is implemented on reconfigurable field programmable gate array (FPGA) platform with ARM core and genetic algorithm processor (GAP). Parallel genetic algorithm based reconfigurable architecture system evolves image filter blocks to explore optimal configuration of filter combinatio...

While the incidence of extreme poverty fell dramatically in China over 1980–2001, progress was uneven over time and across provinces. Rural areas accounted for the bulk of the gains to the poor, though migration to urban areas helped. Rural economic growth was far more important to national poverty reduction than urban economic growth; agriculture played a far more important role than the secon...

The surface V3 of the denuded corneal stroma was separated into the anterior and posterior segments; the swelling ratio of each was compared under zero pressure. In the rabbit, cat, and bovine corneas, the anterior segment was less hydrophilic than the posterior one, in both the central and peripheral regions. In the rabbit cornea, the swelling ratio of the posterior segment was significantly l...

UNLABELLED Genetic robustness (tolerance of mutation) may be a naturally selected property in some viruses, because it should enhance adaptability. Robustness should be especially beneficial to viruses like HIV-1 that exhibit high mutation rates and exist in immunologically hostile environments. Surprisingly, however, the HIV-1 capsid protein (CA) exhibits extreme fragility. To determine whethe...

UNLABELLED BACKGROUND No large scale studies on breastfeeding onset patterns have been carried out in Spain. This work aims to explore the prevalence and the risk factors for not initiating breastfeeding in hospitals from Catalonia (CAT) and Valencia (V), two regions accounting approximately for 30% of the annual births in Spain. METHODS The prevalence of not initiating breastfeeding was c...

Abstract: This research is aimed at improving accuracy of stereolithography (Rapid prototyping) system. The objective of this paper is to detect the flatness of freeform liquid surface. The principle of measurement is performed by obtaining grating image of total reflection from freeform liquid surface. The detection is performed by two steps, coarse detection and fine one. Coarse detection is ...

the millennium development goals (mdgs) are eight international development goals and 21 targets that all countries have agreed to achieve by the year 2015. central asian countries have shown uneven progress in achieving these goals. this paper conducts a comparative study of the impact of economic integration of the regional countries into the world economy on uneven progress of central asian ...

The advancement of mechatronic devices and computer science has provided an impulse to fast-moving robotic technology in last decades. Taking the category of robots as an example, besides the industrial robots for manufacturing, the list of emerging robots for spaceflight, navigation, medical nursing, service, military purposes and so on, are growing (Yang et al., 2007). Further, there are many...
