To avoid un-realistic solutions like expansion shocks from appearing as a part of a solution it is necessary to satisfy the entropy condition for the Roe scheme. A variety of entropy fix formulae for the Roe scheme have been addressed in the literature. Three of the most famous are due to Harten-Hyman and Hoffmann-Chiang. These formulations have been assessed in this paper by applying them to t...

-This article introduces a new neural network architecture, called A R T M A P , that autonomously learns to class(~v arbitrarily many, arbitrarily ordered vectors into recognition categories based on predictive success. This supervised learning system is" built up from a pair of Adaptive Resonance Theory modules (ART, and ARTh) that are capable o f self-organizing stable recognition categories...

Epidemiologic studies indicate that green tea consumption decreases cancer risk (1–3). These data are supported by the results of numerous preclinical studies, which have shown that green and black tea are potent inhibitors of carcinogenesis in various rodent models (4–6), including models for cancers of the skin, lung, esophagus, stomach, liver, duodenum, small intestine, pancreas, colon-rectu...

-The recognition o f three-dimensional ( 3-D ) objects from sequences o f their two-dimensional ( 2-D ) views is modeled by a family o f self-organizing neural architectures, called VIEWNET, that use View Information Encoded With NETworks. V IEWNET incorporates a preprocessor that generates a compressed but 2-D invariant representation o f an image, a supervised incremental learning system that...

This year, more than 400,000 people in the United States will die from a tobacco-related disease because they smoke cigarettes, just as 400,000 or more people have died early from tobacco each year for the past 20 years. It is more than the number of people who will die from automobile accidents, alcohol, AIDS, heroin, homicides, suicides, and fires, combined. Almost all of these Americans bega...

Background/Aims: Prostate cancer represents the cancer with the highest worldwide prevalence in men. Chromosome 8p23 has shown suggestive genetic linkage to earlyonset familial prostate cancer and is frequently deleted in cancer cells of the urogenital tract. Within this locus some -defensin genes (among them DEFB4 , DEFB103 , DEFB104 ) are localized, which are arranged in a gene cluster shown ...

This paper shows how knowledge, in the form of fuzzy rules, can be derived from a. self-organizing supervised learning neural network called fuzzy ARTMAP. Rule extraction proceeds in two stages: pruning removes those recognition nodes whose confidence index falls below a selected threshold; and quantization of continuous learned weights allows the final system state to be translated into a usab...

introduction regional inequality on social and economic grounds is one of the important obstacle in economic development. thus, one of the main issues for policy making and planning in designing a comprehensive social and economic plan is the balanced development in different regions. the recognition of each region situation in relation to other cases is a necessary factor in decreasing inequal...

Wilms’ tumor is the most frequently occurring renal tumor in children and is one of the most treatment-responsive tumors. A tumor-suppressor gene and other genetic abnormalities have been implicated in its etiology. In addition, patients with several congenital anomalies, such as Beckwith-Wiedemann syndrome, WAGR syndrome, and DenysDrash syndrome, have an increased risk of Wilms’ tumor. Previou...
