INTRODUCTION AND BACKGROUND Virtual electrodes formed by field stimulation during defibrillation of cardiac tissue play an important role in eliciting activations. It has been suggested that the coronary vasculature is an important source of virtual electrodes, especially during low-energy defibrillation. This work aims to further the understanding of how virtual electrodes from the coronary va...

1. A considerable proportion of R. pipiens caught in the spring and stored without food for several weeks at about 4 degrees C. had gastrocnemii that did not break down glycogen when they contracted anaerobically to complete exhaustion. A smaller number of the same muscles did not produce lactate. 2. There was no evident relation between failure to break down glycogen and the glycogen content o...

This experimental work aims at probing current-induced forces at the atomic scale. Specifically it addresses predictions in recent work regarding the appearance of run-away modes as a result of a combined effect of the non-conservative wind force and a 'Berry force'. The systems we consider here are atomic chains of Au and Pt atoms, for which we investigate the distribution of break down voltag...

This paper provides a decentralized dynamic foundation of the Nash bargaining solution, which selects an outcome that maximizes the product of the individual gains over the disagreement outcome. Two agents are drawn from a large population and randomly matched to a partnership, if they successfully find an agreeable payoff vector. Abstracting away the details of a search and bargaining process,...

Background: We designed a cross-sectional study to determine electrocardiographic disorders in Down syndrome patients with congenitally normal hearts in a bid to predict fatal cardiac arrhythmia in the future. Materials and Methods: We investigated 60 children with DS without congenital abnormal hearts. Sixty healthy juveniles were also included in the study as a control group. Physical examina...

There are prevailing concerns with the critical dimensions when conventional theories break down. Here we find that the Griffith criterion remains valid for cracks down to 10 nm but overestimates the strength of shorter cracks. We observe the preferred crack extension along the zigzag edge in graphene, and explain this phenomenon by local strength-based failure rather than energy-based Griffith...

In 1980 Miyazaki considered the weight of a job in which weight shows the relative priority over some other job in a sequencing of different jobs. After that some researchers such as Ghanshiam Das, Singh and Singhal [1981], Panwalker [1991] Sotskov, Allahverdi and Lai [2000], Chandramouli (2005) and Belwal, Mittal (2008) had considered the idea of N-job 2 machine flow shop scheduling problem wi...

I speak as one who has been engaged in the educational field in respect of mental health for the last twenty-five years. When my interest in this subject started, early in the 'twenties, it was certainly a practically unknown field, and those of us who have worked in it will realize that we have had not only to try to build up something but to break down something?something which is still not c...

After the fermentation of bovine milk by lactic acid bacteria, rennet was added, and then the curd was formed by incubating at 30°C for 12 hours in the presence of soy protein isolate (SI) or 7S globulin (7S). Cheese was produced from the cooked curd. The texture of the curd and the cheese was studied by break down and cutting tests, respectively. In the break down test of the curd, the order o...

This paper discusses the importance of anticipation and regression in modeling cognitive behavior. The meanings of these cognitive functions are explained by describing our proposed neural network model which has been implemented on a set of cognitive robotics experiments. The reviews of these experiments suggest that the essences of embodied cognition may reside in the phenomena of the break-d...
