In common-onset visual masking (COVM) the target and the mask come into view simultaneously. Masking occurs when the mask remains on the screen for longer after deletion of the target. Enns and Di Lollo [Enns, J. T., & Di Lollo, V. (2000). What's new in visual masking? Trends in Cognitive Sciences, 4(9), 345-352] have argued that this type of masking can be explained by re-entrant visual proces...

The proposed methodology has been implemented in modular system architecture to avoid deadlock situations in real time using a rule base approach. A system configuration consisting of work centers, buffers, robots, and loading/unloading stations is taken with limited capacities as the example case study. A part mix with a variety of processing sequences such as, re-entrant only, jig-jag, re-ent...

UK guidelines no longer recommend routine screening of household contacts of adult patients with extrapulmonary TB (EPTB). From 27 March 2012 to 28 June 2016, we investigated the prevalence of active TB disease in household contacts of 1023 EPTB index cases in North West England, and compared estimates with: published new entrant migrant screening programme prevalence (~147/100 000 person-years...

Mechanisms underlying the genesis of re-entrant substrate for the most common cardiac arrhythmia, atrial fibrillation (AF), are not well understood. In this study, we develop a multi-scale three-dimensional computational model that integrates cellular electrophysiology of the left atrium (LA) and pulmonary veins (PVs) with the respective tissue geometry and fibre orientation. The latter is reco...

The aim of this study was to establish the role played by anisotropic diffusion in (i) the number of filaments and epicardial phase singularities that sustain ventricular fibrillation in the heart, (ii) the lifetimes of filaments and phase singularities, and (iii) the creation and annihilation dynamics of filaments and phase singularities. A simplified monodomain model of cardiac tissue was use...

AIMS Right atrial (RA) tachycardias may involve several mechanisms other than typical isthmus-dependent flutters, particularly in patients with congenital heart disease (CHD) or structural heart disease. We aimed at investigating the clinical utility of non-contact mapping in the diagnosis and ablation of these complex arrhythmias. METHODS AND RESULTS Non-contact mapping was used to treat RA ...
