our city's slums. A fire, unusual in its intensity, lit her brown eyes? unusual, even for one of her race. Her face was a narrow oval, her features classically perfect, her skin a fine transparent brown through which burned an enchanting glow; her hair, coal black and shining with a luster that 110 hair oil could impart, was drawn back from a low, smooth forehead. Her slender figure had a willo...

Single-molecule Förster Resonance Energy Transfer (smFRET) allows probing intermolecular interactions and conformational changes in biomacromolecules, and represents an invaluable tool for studying cellular processes at the molecular scale. smFRET experiments can detect the distance between two ƒuorescent labels (donor and acceptor) in the 3-10 nm range. In the commonly employed confocal geomet...

Bidirectional reflectance distribution function provides a physical description of material appearance. In particular, it helps to describe the gloss. We suggest that, at least, one attribute of gloss: Contrast gloss (luster), may be described directly from an image by using local image contrast measurement. In this article, we investigate the relation between image contrast measures, gloss per...

Applications of so‰ware de€ned networking (SDN) concepts to infrastructure-less wireless networks are substantially unexplored, mainly because of the complex nature of the distributed control problems and of the unavailability of a high-speed backhaul. Œis article presents an initial aŠempt at developing a principled approach to so‡ware-de€ned wireless networking based on cross-layer optimizati...
