In the future, facilities that are probable terrorist targets may be protected by weather analysis and forecasting systems that are part of automated capabilities that warn of the approach of hazardous chemical, biological, or radiological (CBR) material in the atmosphere. Based on information provided by coupled meteorological and transport and dispersion (T&D) models and networked sensors, bu...

This work, conceptually envisaged by Prof. R. B. Fisher, undertook the augmentation of one of the original approaches in the dense stereo eld by Cox et al. [1]. The aim was to introduce explicit vertical constraint into the Cox algorithm and reduce the streaking and speckling noise e ects commonly associated with stereo results from this approach. These e ects are commonly attributed to the lac...

We present an investigation of the structural and electronic properties of an ordered grain boundary (GB) formed by separated pentagon-heptagon pairs in single-layer graphene/SiO2 using scanning tunneling microscopy/spectroscopy (STM/STS), coupled with density functional theory (DFT) calculations. It is observed that the pentagon-heptagon pairs, i.e., (1,0) dislocations, form a periodic quasi-o...

The term information war (IW) helped describe one aspect of the unfolding revolution in military affairs in the 1990s. Today, technological developments are integrating the data processing capabilities of machines and the mind in ways not possible a decade ago. As a result, the old IW paradigm may no longer be applicable, making other potential paradigms and terms worthy of consideration. As th...

We consider the high energy limit of the colour ordered one-loop five-gluon amplitude in the planar maximally supersymmetric N = 4 Yang-Mills theory in the multiRegge kinematics where all of the gluons are strongly ordered in rapidity. We apply the calculation of the one-loop pentagon in D = 6−2ǫ performed in a companion paper [1] to compute the one-loop five-gluon amplitude through to O(ǫ2). U...
