Positron range estimations with PeneloPET [PDF]
Physics in Medicine and Biology, 2013 Technical advances towards high resolution PET imaging try to overcome the inherent physical limitations to spatial resolution. Positrons travel in tissue until they annihilate into the two gamma photons detected. This range is the main detector-independent contribution to PET imaging blurring.

Target Association of Heterogeneous Sensors Based on Nearest-neighbor and Topology
Leida xuebao, 2012 A new data association algorithm is proposed in this paper for heterogeneous sensors information fusion system, which consists of Radar and high-dynamic-range IR, based on joint usage of the nearest-neighbor (NN) and the topology similarity. The proposed

Estimated mink home ranges using various home‐range estimators
Wildlife Society Bulletin, 2018 ABSTRACT Although the American mink ( Neovison vison ) is a fairly common and valued semiaquatic furbearing species, studies evaluating space use by mink in North America are scarce. We implanted radiotransmitters in 8 male and
