Previously, switched dynamical systems have been studied in terms of switching that occurs at a common border between two regions in the same space as the system trajectory crosses the border. However, models arising from this consideration cannot cover systems whose trajectories do not actually “cross” the border. A typical example is the currentmode controlled boost converter whose trajectory...

Humans are capable of rapidly determining whether regions in a visual scene appear as figures in the foreground or as background, yet how figure-ground segregation occurs in the primate visual system is unknown. Figures in the environment are perceived to own their borders, and recent neurophysiology has demonstrated that certain cells in primate visual area V2 have border-ownership selectivity...

Editor's Note: These short, critical reviews of recent papers in the Journal, written exclusively by graduate students or postdoctoral fellows, are intended to summarize the important findings of the paper and provide additional insight and commentary. For more information on the format and purpose of the Journal Club, please see Review of Fang et al. The classic problem of figure-ground segreg...

Knowledge of the dynamic security border can provide an operator with valuable information on how to safely steer the power system away from vulnerable operating regions. The large set of non-linear differential equations that describe modern large-scale power systems makes it difficult to determine the security border either analytically or numerically in real time. As an alternative, neural n...

Natural images are usually cluttered because objects occlude one another. A critical aspect of recognizing these visual objects is to identify the borders between image regions that belong to different objects. However, the neural coding of border ownership in human visual cortex is largely unknown. In this study, we designed two simple but compelling stimuli in which a slight change of context...

In much of the previous study of switched dynamical systems, it has been assumed that switching occurs at a common border between two regions in the same space as the system trajectory crosses the border. However, models arising from this consideration cannot cover systems whose trajectories do not actually “cross” the border. A typical example is the current-mode controlled boost converter who...

European integration has had a dual impact on border regions. On the one hand, borders were physically dismantled across most of the EU’s internal territory. On the other hand, they have become a fertile ground for territorial co-operation and institutional innovation. The degree of cross-border co-operation and organization achieved varies considerably from one region to another depending on a...

The paper focuses on the tourism development strategy of the Amur Oblast called “Twin Cities”. Said initiative became the first attempt of the Russian Far Eastern regions to create the hospitality industry towards Chinese tourists in the Sino-Russian borderlands. Bringing together such sub-disciplines as border tourism, urban planning and territorial development helps to find out the peculiarit...

B asal cell carcinoma (BCC) involving the vermilion border and mucosal surface of the lips is rare, whereas these sites are more frequently involved by squamous cell carcinoma (SCC). The epithelium of the lip is divided into 4 regions: the skin; the vermilion border; the outer mucosa (vermilion); and the inner mucosa. The vermilion border contains the orbicularis oris muscle without a subcutane...
