The feedback control of border collision bifurcations is considered for two-dimensional discrete-time systems. These are bifurcations that can occur when a fixed point of a piecewise smooth system crosses the border between two regions of smooth operation. The goal of the control effort is to modify the bifurcation so that the bifurcated steady state is locally unique and locally attracting. In...

The present paper compares the impact of domestic acquisitions and cross-border acquisitions on Indian acquirer shareholders’ wealth during 2003-2008. A segregated analysis has also been conducted to measure the impact of stake/control acquired, based on a sample of acquisitions of 268 domestic and 255 target firms across border. Further, this paper also analyses the short-run performance of pe...

Na(+)/H(+) exchanger (NHE)3 is the predominant NHE on the brush-border membrane of the proximal tubule in adult animals. NHE8 has been localized to the brush-border membrane of proximal tubules and is more highly expressed in neonates than in adult animals. However, the relative role of NHE8 in neonatal renal acidification is unclear. The present study examined if there was a compensatory incre...

Approximately 11.5 million people reside in the 42 counties and 39 Mexican municipalities located along the U.S.-Mexico border, and 86% of those people reside in 14 pairs of sister cities, metropolitan areas divided by the international border (1). Border residents share similar resources and environmental problems: issues of great concern include air quality, water quantity and quality, and an...

To investigate the molecular mechanisms responsible for the temporal and spatial control of cell movements during development, we have been studying the migration of a small group of follicle cells, called the border cells, in the Drosophila ovary. Timely initiation of border cell migration requires the product of the slow border cells (slbo) locus, which encodes the Drosophila homolog of the t...

BACKGROUND Epidermal growth factor (EGF) has been shown to increase intestinal absorptive surface area and transport function in normal animals. AIMS To examine the effect of EGF on absorptive surface area and brush border membrane function in a model of massive small bowel resection. METHODS New Zealand white rabbits were randomised into two groups: a resected group (60% proximal small bow...

Border control is vital to the security of a nation and its citizens. All countries look at measures to improve the security of their borders. But increasing security can bring a substantial financial burden. In this study, we analyze the border security problem of Turkey using a simulation approach. Our main objective is to find more efficient ways of improving border control and security alon...

Feedback controls that stabilize border collision bifurcations are designed for piecewise smooth systems undergoing border collision bifurcations. The paper begins with a summary of the main results on border collision bifurcations, and proceeds to a study of stabilization of these bifurcations for one-dimensional systems using both static and dynamic feedback. The feedback can be applied on on...

Abstract This article explores the potential of historical narratives to inform and guide action, taking case border control in Hungary. The Hungarian government has recently criminalised irregular crossing made a comparison between Ottoman Occupation contemporary challenges mass migration legitimise its new measures. Qualitative interviews conducted 2019 seem suggest that some members police, ...
