In this paper, we propose a new data mining approach, called dAR, for discovering interesting association rules and their changes by evolutionary computation. dAR searches through huge rule spaces effectively using a genetic algorithm. It has the following characteristics: (i) it encodes a complete set of rules in one single chromosome; (ii) each allele encodes one rule and each rule is represe...

Pit latrines are the main form of sanitation in unplanned areas in many rapidly growing developing cities. Understanding demand for pit latrine fecal sludge management (FSM) services in these communities is important for designing demand-responsive sanitation services and policies to improve public health. We examine latrine emptying knowledge, attitudes, behavior, trends and rates of safe/unsa...

Pre-symptomatic drought stress prediction is of great relevance in precision plant protection, ultimately helping to meet the challenge of “How to feed a hungry world?”. Unfortunately, it also presents unique computational problems in scale and interpretability: it is a temporal, large-scale prediction task, e.g., when monitoring plants over time using hyperspectral imaging, and features are ‘t...

Pseudomonas chlororaphis PCL1606 synthesizes the antifungal antibiotic 2-hexyl, 5-propyl resorcinol (HPR), which is crucial for the biocontrol of fungal soil-borne pathogens. The genetic basis for HPR production lies in the dar genes, which are directly involved in the biosynthesis of HPR. In the present study, we elucidated the genetic features of the dar genes. Reverse transcription PCR exper...

Ante el inminente cambio del tradicional ISBN de 10 dígitos al ISBN de 13 dígitos, que empezará a utilizarse a partir del 1 de enero de 2007, este artículo recoge algunos de los problemas que pueden surgir a partir de este cambio. Se presentan las soluciones (provisionales o definitivas) que ya han previsto algunos centros y redes bibliotecarias, como la Library of Congress, OCLC o el RLG en lo...

BACKGROUND Multidetector computed tomography is useful for determining the appropriate transcatheter heart valve (THV) size in patients with severe aortic stenosis who are suboptimal surgical candidates. The relationship between adherence to the recommended CoreValve sizing algorithm and clinical outcomes is not known. METHODS AND RESULTS We evaluated 1023 patients with severe aortic stenosis...

Habitat fragmentation may strongly affect species density, species interactions, and the rate of ecosystem processes. It is therefore important to understand the observed variability among species responses to fragmentation and the underlying mechanisms. In this study, we compare density-area relationships (DARs) for 344 lepidopteran species belonging to 22 families (butterflies and moths). Thi...

An analytic study was conducted on coupled partial differential equations. We formally derived new solitary wave solutions of generalized coupled system of Zakharov-Kuznetsov (ZK) and KdV equations by using modified extended tanh method. The traveling wave solutions for each generalized coupled system of ZK and KdV equations are shown in form of periodic, dark, and bright solitary wave solution...
