Quality variations are introduced in the circular model of differentiated products. Two main game structures are analyzed. The three-stage game has entry in the first stage, location in the second, and quality and price choice in the third. The four-stage game replaces the quality and price subgame of the three-stage game with two stages, quality choice followed by price choice. It is found tha...

Meeting the required objectives of the Medicare and Medicaid Electronic Health Record (EHR) Incentive Programs is a high priority for most medical practice managers and their employers and staff. Failure to meet even one of the objectives established by the Centers for Medicare & Medicaid Services (CMS) results in the eligible professional receiving no incentive payment. A key element of the In...

Neural network models of categorical perception (compression of within-category similarity and dilation of between-category differences) are applied to the symbol-grounding problem (of how to connect symbols with meanings) by connecting analog sensorimotor projections to arbitrary symbolic representations via learned category-invariance detectors in a hybrid symbolic/nonsymbolic system. Our net...

Expression of CD4, the principle receptor for HIV-1, is not sufficient for viral entry into most non-human and rare human cell lines. Construction of HIV-1 susceptible heterokaryons and a hybrid cone by fusion of HeLa cells and the HIV-1 resistant human cell line U373-CD4 were previously reported by us. These results suggested that U373-CD4 lack a cofactor(s) which is essential for HIV-1 entry ...

INTRODUCTION Studies suggest students who are substantially older than the average age for their grade engage in risky health behaviors, including substance use. However, most studies do not account for the distinct reasons why students are old for their grade (ie, grade retention vs delayed school entry) or for their pubertal stage. Thus, whether the association between age for grade and subst...

The present paper describes a three stage technique to parse Hindi sentences. In the first stage we create a model with the features of head words of each chunk and their dependency relations. Here, the dependency relations are inter-chunk dependency relations. We have experimentally fixed a feature set for learning this model. In the second stage, we extract the intra-chunk dependency relation...

Plant height, which shows dynamic development and heterosis, is a major trait affecting plant architecture and has an indirect influence on economic yield related to biological yield in cotton. In the present study, we carried out dynamic analysis for plant height and its heterosis by quantitative trait loci (QTL) mapping at multiple developmental stages using two recombinant inbred lines (RILs...
