The idea of data transfer by physically severed connections has been applied in a simple realization of the Lock-Keeper technology, the SingleGate Lock Keeper system. By means of it, the possibility of direct attacks to a protected network can be eliminated entirely and data can be exchanged between two networks through a completely secure and reliable way. As an advanced implementation of this...

This field experiment investigated the relative merits of approaching the penalty kick with either a keeper-independent or keeper-dependent strategy. In the keeper-independent strategy, the shooter selects a target location in advance and disregards the goalkeeper's actions during the run-up. In the keeper-dependent strategy, the shooter makes a decision resting on the anticipation of the goalk...

Penalty takers in association football adopt either a keeper-independent or a keeper-dependent strategy, with the benefits of the keeper-independent strategy presumed to be greater. Yet, despite its relevance for research and practitioners, thus far no method for identifying penalty kick strategies has been available. To develop a validated and reliable method, Experiment 1 assessed characteris...

Reduction in leakage power has become an important concern in low-voltage, low-power, and highperformance applications. International Technology Roadmap for Semiconductors projects that leakage power consumption may come to dominate total chip power consumption as the technology feature size shrinks. A novel approach for ultra-low leakage CMOS circuit structure is “Sleepy keeper.” Sleepy keeper...

A variable threshold voltage keeper circuit technique is proposed for simultaneous power reduction and speed enhancement of domino logic circuits. The threshold voltage of a keeper transistor is dynamically modified during circuit operation to reduce contention current without sacrificing noise immunity. The variable threshold voltage keeper circuit technique enhances circuit evaluation speed b...

Families cannot be exchanged or denied. There is a sad futility about wishing our families were otherwise. So it is with the community of general practitioners to which we all belong. We share the same title, and will be judged collectively whether we like it or not. We may not want to account for some of our colleagues. We may try to surround ourselves with like-minded doctors and pretend that...

Stockmanship is a term used to describe the management of animals with a good stockperson someone who does this in a in a safe, effective, and low-stress manner for both the stock-keeper and animals involved. Although impacts of unfamiliar zoo visitors on animal behaviour have been extensively studied, the impact of stockmanship i.e familiar zoo keepers is a new area of research; which could re...

An ion thruster discharge cathode assembly (DCA) erosion theory is presented based on near-DCA NSTAR plasma potential measurements and experimental results for propellant flow rate effects on ion number density. The plasma potential structures are utilized in an ion trajectory algorithm to determine the location and angle at the DCA keeper of bombarding ions. These results suggest that the plas...
