The existence of a new phenomena – giant electron-gamma bursts is established. The bursts are generated in thunderclouds as a result of the combined action of runaway breakdown and extensive atmosphere showers (RB-EAS). The experiments were fulfilled at the Tien Shan Mountain Scientific Station using EAS-Radio installation. This specially constructed installation consists of a wide spread EAS t...

The dynamic relationship between hypernorms and microsocial contracts can explain novel, evolutionary changes in economic life. The conceptual machinery of Integrative Social Contracts Theory (ISCT) can be expanded in order to understand dynamic moments in the evolution in economic life such as the economic crisis of 2008–2009. When a transition in the ethical interpretation of economic events ...

In contrast to past centuries, scientific researchers have been currently conducted systematically in all countries as part of an education strategy. As a consequence, scientists have published thousands of reports. Writing an effective article is generally a significant problem for researchers. All parts of an article, specifically the abstract, material and methods, results, discussion and re...

The hypothesis that "ideas often flow from radio and print to opinion leaders and from these to the less active sections of the population" has been tested in several successive studies. Each study has attempted a different solution to the problem of how to take account of interpersonal relations in the traditional design of survey research. As a result, the original hypothesis is largely corro...

While a key function of contracts is to provide incentives, the incentives of judges to enforce the terms of a contract have rarely been examined. This paper develops a simple model of judicial agency in which judges are corrupt and can be bribed by contracting parties. Higher-powered contracts expose contracting parties to more frequent and more severe corruption, which in turn lessens the inc...

PURPOSE Given the extensive data stored in healthcare data warehouses, data warehouse governance policies are needed to ensure data integrity and privacy. This review examines the current state of the data warehouse governance literature as it applies to healthcare data warehouses, identifies knowledge gaps, provides recommendations, and suggests approaches for further research. METHODS A com...

The key features leading to low-energy grain boundaries in metals are discussed by reference to computersimulated structures and geometrical analysis in terms of atom packing. Low energy is found to be associated with boundary structures consisting of relatively dense packing, and this can in turn be expressed in terms of the space-filling packing of coordination polyhedra. The geometrical meth...

False-positive classification is a central issue for RFID environments with limited process control, such as in-store settings. In the case of electronic article surveillance, false positives not only lead to incorrect inventory data but also trigger false alarms, which impair customer satisfaction. A typical counter measure is to reduce antenna power, which in turn leads to greatly diminished ...

We present a definition of Riemannian manifold in noncommutative geometry. Using products of unbounded Kasparov modules, we show one can obtain such Riemannian manifolds from noncommutative spinc manifolds; and conversely, in the presence of a spinc structure. We also show how to obtain an analogue of Kasparov's fundamental class for a Riemannian manifold, and the associated notion of Poincaré ...
