Location based services(LBS)are widely utilized,and determining the location of users’IP is the foundation for LBS.Constrained by unstable delay and insufficient landmarks,the existing geolocation algorithms have pro...
Most long-distance migrating passerines that breed in Europe spend their winters in Africa,with only a few species migrating eastward to spend the non-breeding period in South Asia.The use of the Indo-European flyway ...
The protocol was first approved(July 22,2005)by the US Department of the Air Force(Protocol FAC2005026H);Subsequently(October 11,2005);the Institutional Review Board(IRB)at the University of Florida,Gainesville,FL,USA approved the research(document IRB#474-2005);did the US Department of Veteran’s Affairs(October 19,2005,VA#0001).
Isotopic signatures used in the georeferencing of human remains are largely fixed by spatially distinct geologic and environmental processes.However,location-dependent temporal changes in these isotope ratios should a...
