On spatio-temporal constraints and inheritance in role-based access control
Pervasive computing environments have created a requirement for spatial- and temporal-aware access control systems. Although temporal, spatial and spatio-temporal role-based acces...

Monte Carlo assessment of time-of-flight benefits on the LYSO-based discovery RX PET/CT scanner
Time-Of-Flight (TOF) positron emission tomography (PET) was studied and preliminarily developed in the 80s, but the lack of a scintillator able to deliver proper time resolution a...

Resonant spatiotemporal learning in large random recurrent networks
Taking a global analogy with the structure of perceptual biological systems, we present a system composed of two layers of real-valued sigmoidal neurons. The primary layer receives...
