Wheat–cotton double cropping practices on a large scale in cotton belt of the Yellow RiverValley and the Yangtze River Valley in China. Field experiments were conducted to determinethe effects of wheat–cotton double cropping on cotton biomass accumulation and yieldformation during 2011/12 and 2012/13 growing seasons. Two cotton cultivars, Siza 3 (mid–latematurity) and CCRI 50 (early maturity), ...

Some species do appear to practise construction skills — birds in particular — and to require some mental flexibility in starting the process. But ultimately, animals build the way they do because they are genetically programmed to do so, Hansell concludes. But evolution can lead to surprising results. Hansell notes that most of our closest primate relatives create little more than temporary sh...

In this paper we describe a system that uses patterns of eye blinks as a biometric. Each user chooses a personal blink pattern based on a song (for example “Jingle Bells”). To establish their identity, the user looks at the system’s camera and blinks to the cadence of their chosen song. Computer vision is used to detect the blinks and to compare the blinked cadence to a database of stored blink...

Exotic germplasm, that is, germplasm without commercial applicability, can broaden the genetic base in upland cotton (Gossypium hirsutum L.). The objectives of this study were to determine combining ability and identify parents from exotic germplasm for breeding. Twelve regionally adapted exotic germplasm lines were crossed with one cultivar and three elite germplasm lines in a North Carolina D...
