BACKGROUND The role of intracellular calcium (Ca(i)) in defibrillation and vulnerability is unclear. METHODS AND RESULTS We simultaneously mapped epicardial membrane potential and Ca(i) during shock on T-wave episodes (n=104) and attempted defibrillation episodes (n=173) in 17 Langendorff-perfused rabbit ventricles. Unsuccessful and type B successful defibrillation shocks were followed by het...

wireless sensor network has been used for data sensing and collection at a single point for decision making process. Attack comprising in WSN produced various issues in data transmission and data management. Sinkhole attack is a compromised attack in WSN that compromised nodes that advertises a shortest path for data transmission. In this paper a new approach has been purposed for detection of ...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This document describes an operational technique that uses BGP communities to remotely trigger black-holing of a particular destination network to block denial-of-service attacks. Black-holing can be applied on a se...

Sinkhole development occurs in many areas of the world where soluble rocks crop out. Sinkholes are generally the surface expression of the presence of caves and other groundwater flow conduits in carbonate rocks, which are solutionally enlarged secondary permeability features. Their formation may be either natural or caused by man’s activities. In both cases, heavy consequences have to be regis...

Three dangerous attacks in wireless sensor network is handled in this proposed security solution. This paper proposes a lightweight and fast mobile agent technology based security solution against cloning attack, sinkhole attack and black hole attack for wireless sensor networks (WSNs).Recently mobile agents have been proposed in wireless sensor networks to reduce the communication cost especia...

This paper investigates one of the most severe routing attacks in sensor networks, namely sinkhole attack. A compromised node tries to draw all or as much traffic as possible from a particular area, by making it look attractive to the surrounding nodes with respect to the underlying routing metric. The detection of sinkhole attack in wireless sensor networks is proposed using an enhanced double...

This paper forms part of the SINEW (sinkhole early warning) project and continues work conducted by Möller co-workers in 2022, where 1g experiments demonstrated feasibility using distributed fibre-optic sensing (DFOS) for sinkhole warning. Their experimental campaign highlighted an order magnitude difference strain between soil cable that remains unexplained weakens confidence technology and/or...

In recent, the placement of backfill in underground mines has emerged as a new paradigm in research as it not only improves safety but also allows disposal of byproducts including coal ash. In this regards, this paper addresses the backfilling challenges in limestone mine to prevent sinkhole and subsidence. Limestone mines, generally regarded as being safer than coal and metal mines, have been ...
