Estimation of crop production can be a very useful tool while planning a nation’s agriculture. The use of statistical techniques in developing such tools is a popular and well studied problem. In this paper, we present a statistical model that predicts the total crop production for a geographical region, given the season of harvest and the total land used. We apply this model on four major crop...

We present a cortical model of cognitive control based on attractor networks, correlational learning, and gating. Our model does not make use of production rules or local representations. It is capable of completing a demonstration task requiring adding to and examining working memory. The architecture used is easily generalizable to other tasks.

Childhood asthma is typically associated with a polarized Th2 response to inhaled allergens and is influenced by genetics. Yang et al. show that the asthma susceptibility gene DENND1B controls cytokine production in Th2 lymphocytes by controlling the rate of TCR internalization and routing to endosomes, providing a molecular basis for how DENND1B contributes to asthma pathogenesis.

We determined the prevalence of Escherichia coli O157:H7 in organically and naturally raised beef cattle at slaughter and compared antibiotic susceptibility profiles of the isolates to those of isolates from conventionally raised beef cattle. The prevalences of E. coli O157:H7 were 14.8 and 14.2% for organically and naturally raised cattle, respectively. No major difference in antibiotic suscep...

This paper looks at differences in spatial and temporal variation of rice yields in China and Brazil. We find that rice yields in China have converged over time and that rice production has become more and more homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypotheses are put forward to explain the different beha...

We would like to thank our co-editors, editorial board members, guest editors, referees and authors that have contributed to JTAER with new ideas and editorial work during the last seven years. Based on their suggestions last year we implemented the Editorial Board Communications System, and this year we are implementing a platform to support of a research network and an alert system. Together ...

This research is derived an integrated model of economic production quantity, inspection and preventive maintenance to incorporate rework, minimal repair and inspection time for an imperfect production system. Some proportions of non-conforming items are assumed scrap before the rework process start and others are reworked. The rework process is imperfect that is a proportion of the reworked it...

In the beef production system, 70-75% of the total dietary energy is used for maintenance (Ferrell and Jenkins 1984; NRC 1996; Montaldo-Bermudez et al. 1990). Thus, while only 5% of the total life cycle dietary energy consumption is used for protein deposition in beef cattle, swine and poultry are more efficient at 14 and 22%, respectively. The relatively large size, slow maturity and slow repr...
