this paper measures event risk which is introducing by the ball committee to measure the effect of sudden news. this study calculates event risk by using the data of registered firms in tehran stock market between 1993 and 1994. for computing event risk, we use daily market capitalization for 80 firms during 1993-2009, then dividing these firms to three baskets; big, medium and small. the model...

Background: Basal Cell Carcinoma (BCC) is a type of non-melanoma skin cancer. Alteration in gene expression is the important event that happens in cancer cell. Detection of this event is possible by proteomics techniques. Methods: Normal and tumor tissues were taken from BCC patient. Total proteins were purified by standard methods, and proteins were separated by two-dimensional electrophoresis...

This paper reviews the theoretical bases of the barrier modelling analysis, and introduces a novel approach for considering the barrier effects on the probability of the events through the event tree analysis. A structure for modelling barrier sets is developed. Using the techniques of the reliability analysis, an approach for calculating the effects of the barriers on the probability of events...

Two representative watersheds, Ammameh and Kasilian, located in Southern and Norten Elborz mountain in Iran respectively were considered. Fourteen events of rainfall-runoff in nonmelting seaons were chosen and their storms and flood hydrographs were gathered from an automatic recording station. Base flow separation was made by recession limb analysis while Philip equation was used for the calcu...

Many interesting application systems, ranging from workflow management and CSCW to air traffic control, are eventdriven and time-dependent and must interact with heterogeneous components in the real world. Event services are used to glue together distributed components. They assume a virtual global time base to trigger actions and to order events. The notion of a global time that is provided by...

The base following stop codons in mammalian genes is strongly biased, suggesting that it might be important for the termination event. This proposal has been tested experimentally both in vivo by using the human type I iodothyronine deiodinase mRNA and the recoding event at the internal UGA codon and in vitro by measuring the ability of each of the 12 possible 4-base stop signals to direct the ...

Abs t rac t Planning in any realistic sett ing requires the management of an enormous amount of in format ion. This in format ion is generally temporal in nature; predict i on , plan choice, and debugging all involve reasoning about t ime. The assertions manipulated by t radi t ional predicate-calculus data base systems, such as Prolog, are timelessly t rue. In the temporal data base system des...

Describing and extracting event semantic information is essential to build an event knowledge base and applications in event and semantic level. However, most existing work deals with documents so they fail to provide sufficient semantic information about events in news articles. In this paper, considering What, Who, When, Where, Why and How, the 5W1H elements of a piece of news, we propose a N...

Due to the varying rates of change of ephemeral administrative and enduring clinical knowledge in decision support systems (DSSs), the functional partition of knowledge base (KB) components can lead to more efficient and cost-effective system implementation and maintenance. Our prototype loosely couples a clinical event monitor developed by Columbia University Medical Center (CUMC) with a secur...
