Biologists identify reproductive 'traffic cop'
Sarit Smolikove biology reproduction fertility chromosomes research
2017/2/16
Before an egg becomes fertilized, sets of chromosomes must pair up to pass along genetic information. This happens within each reproductive cell, where separate chromosomes of male and female origin m...
Flash sourcing, or rapid detection and characterization of earthquake effects through website traffic analysis
Monitoring Seismic risk Algorithms and implementation
2015/8/27
This study presents the latest developments of an approach called ‘flash sourcing’, which provides information on the effects of an earthquake within minutes of its occurrence. Information is derived ...

Differences in Voluntary Cow Traffic between Holstein and Illawarra Breeds of Dairy Cattle in a Pasture-based Automatic Milking System
Breed Voluntary Cow Traffic Automatic Milking System
2016/5/16
Automatic milking systems (AMS) rely upon voluntary cow traffic (the voluntary movement of cattle around a farm) for milk harvesting and feed consumption. Previous research on conventional milking sys...
Exploiting Channel Correlation and PU Traffic Memory for Opportunistic Spectrum Scheduling
Cognitive radio networks spectrum server temporal correlation partially observable Markov decision processes genie-aided system
2012/4/23
We consider a cognitive radio network with multiple primary users (PUs) and one secondary user (SU), where a spectrum server is utilized for spectrum sensing and scheduling the SU to transmit over one...
