OBJECTIVE Natural disasters and rapidly aging populations are chronic problems for societies worldwide. We investigated the effects of an intervention in Japan known as Ibasho, which embeds elderly residents in vulnerable areas within larger social networks and encourages them to participate in leadership activities. This project sought to deepen the connections of these elderly residents to so...

OBJECTIVE To examine trends in long term survival in patients alive 28 days after myocardial infarction and the impact of evidence based medical treatments and coronary revascularisation during or near the event. DESIGN Population based cohort with 12 year follow-up. SETTING Perth, Australia. PARTICIPANTS 4451 consecutive patients with a definite acute myocardial infarction according to t...

the adverse effect of climate change on agriculture has increased the importance of weather index insurance, particularly in developing countries. by using several econometric models, this study estimated the price and evaluated its effectiveness in rainfall index insurance for rice and wheat in nepal. crop yields associated with seasonal rainfall in three crop reporting districts were applied ...

The Top-K problem is defined as follows. Given L lists of real numbers, find the top K scoring L-tuples. A tuple is scored by the sum of its components. Rare event modeling and event ranking are often reduced to the Top-K problem. In this paper, we present the application of a fixedmemory heuristic search algorithm (namely, SMA*) and its distributed-memory extension to the Top-K problem. Our ap...

Now days, internal combustion engines are used in most of the automobiles and mechanical machineries. The piston is a part without which no internal combustion engine can work i.e., piston plays a vital role in almost all types of vehicles. So, the reliability of piston manufacturing system is most essential for the proper functioning of vehicles. In this paper, fault tree method is used to ana...

In the context of topcolor assisted technicolor(TC2) models, we study the production of the top-pions π t with single top quark via the processes pp̄ → tπ0 t+X and pp̄ → tπ t + X, and discuss the possibility of detecting these new particles at Tevatron and LHC. We find that it is very difficult to observe the signals of these particles via these processes at Tevatron, while the neutral and charge...
