Comprehensive mapping of transcription factor binding sites is essential in postgenomic biology. For this, we propose a mining approach combining noisy data from ChIP (chromatin immunoprecipitation)-chip experiments with known binding site patterns. Our method (BoCaTFBS) uses boosted cascades of classifiers for optimum efficiency, in which components are alternating decision trees; it exploits ...

Every organism on earth relies on associations with its neighbors to sustain life. For example, plants form associations with neighboring plants, microflora, and microfauna, while humans maintain symbiotic associations with intestinal microbial flora, which is indispensable for nutrient assimilation and development of the innate immune system. Most of these associations are facilitated by chemi...

Understanding plant cell wall cross-linking chemistry and polymeric architecture is key to the efficient utilization of biomass in all prospects from rational genetic modification to downstream chemical and biological conversion to produce fuels and value chemicals. In fact, the bulk properties of cell wall recalcitrance are collectively determined by its chemical features over a wide range of ...

(Summary) The Flixborough Works of Nypro (UK) Ltd. were demolished at about 4:53 p.m. on Saturday June 1st. 1974, by an explosion of warlike dimensions which was the equivalent of 15 tonnes of TNT.

Outs ide t he works in juries and damage were widespread. 53 people were recorded as casualties, whil...

In the present work, a comprehensive study was made on the analysis of chemical composition of essential oil and antibacterial activity from the leaves of Ajuga bracteosa. The essential oil was extracted by Cleavenger type apparatus and analyzed by GC-MS. The main components present in the essential oil of leaves are Limonene, α-humulene, β-Myrcene, Elemol, Camphene, βCaryophellene, α-phellendr...

Hormone concentrations in blood and total 12 h urine values were compared between 40 postmenopausal women with breast cancer and 40 control women in a study which carefully controlled for the possible confounding effects of age, weight and pregnancy history by individually matching cases and controls on these factors. Breast cancer cases had received only surgical treatment for their localised ...

the Center for Plant Cell Biology, Institute for Integrative Genome Biology and Department of Botany and Plant Sciences, University of California, Riverside, California, USA. e-mail: [email protected] Although resources devoted to plant biology are modest in comparison to biomedical and other areas of research, plant biologists will play a disproportionate and crucial role in the future of manki...

This paper discusses the issues involved in applying a generic AI planner to the problem of generating plant operating procedures for chemical process plant. It considers the problem of providing the correct planning facilities, concentrating on dealing with flow of chemicals, and proposes the use and integration of a special purpose planner for valve sequencing. It goes on to consider the know...

in order to evaluate the effects of different organic and chemical fertilizers on yield, yield components and seed oil content of sesame an experiment was conducted in a split plot layout based on randomized complete block design with four replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2006. four types of fertilizer, including chemical fertilize...
