Western countries face an ongoing threat from Improvised Explosive Devices (IEDs). One aspect of the response to this threat is the use of agent-based simulation to model the human networks which place IEDs. While it may not be possible to model these networks with sufficient fidelity to exactly predict IED placement, there is substantial training value in lower-fidelity simulation models which...

Prediction of pulsed or intermittent exposure effects on populations is emerging as an important issue in ecotoxicology. However, the underlying theory of the dose-response models has not been tested rigorously enough to provide a true understanding for predicting the effects of pulsed exposures. Since its introduction, the individual effective dose (IED) theory has remained the dominant explan...

The ability to flexibly adapt to the changing demands of the environment is often reported as a core deficit in fragile X syndrome (FXS). However, the cognitive processes that determine this attentional set-shifting deficit remain elusive. The present study investigated attentional set-shifting ability in fragile X syndrome males with the well-validated intra/extra dimensional set-shifting para...

Improvised explosive devices (IEDs) are common and lethal instruments of terrorism, and linking a terrorist entity to a specific device remains a difficult task. In the effort to identify persons associated with a given IED, we have implemented a specialized content based image retrieval system to search and classify IED imagery. The system makes two contributions to the art. First, we introduc...

A Particle-in-Cell simulation with Monte Carlo Collisions (PIC-MCC) was conducted of the application of tailored DC voltage steps on an electrode, during the afterglow of a capacitively-coupled pulsed-plasma argon discharge, to control the energy of ions incident on the counter-electrode. Staircase voltage waveforms with selected amplitudes and durations resulted in ion energy distributions (IE...
