Dynamic differential evolution (DDE) for shape reconstruction of perfect conducting cylinder (PEC) buried in a half-space is presented. Assume that a conducting cylinder of unknown shape is buried in one half-space and scatters the field incident from another halfspace where the scattered filed is measured. Based on the boundary condition and the measured scattered field, a set of nonlinear int...

Critical Windows p,p ́-DDE May Alter Fetal Neurodevelopment DDT has been widely used to control mosquitoborne malaria since the late 1940s. The compound and metabolites such as p,p ́-DDE linger in the environment for decades; even in areas where DDT has been banned, these neurotoxic chemicals are still detected in human blood, fat, breast milk, and umbil ica l cord blood. Researchers examined the...

Adipose tissue samples from polar bears (Ursus maritimus) were obtained by necropsy or biopsy between the spring of 1989 to the spring of 1993 from Wrangel Island in Russia, most of the range of the bear in North America, eastern Greenland, and Svalbard. Samples were divided into 16 regions corresponding as much as possible to known stocks or management zones. Concentrations of dieldrin (DIEL),...

Target audience. Researchers and clinicians interested in the brain’s microarchitecture and diffusion MR methods. Purpose. Generating a methodology capable of amplifying Double-Diffusion-Encoding MR’s sensitivity towards randomly oriented compartments. Introduction. Double Diffusion Encoding (DDE, Fig. 1A) [1] NMR and MRI techniques – more commonly known as Double Wave Vector (DWV) [2] or doubl...

A wide range of Sensor Networks (SNs) are deployed in real world applications which generate large amount of raw sensory data. Data mining technique to extract useful knowledge from these applications is an emerging research area due to its crucial importance but still it’s a challenge to discover knowledge efficiently from the sensor network data. In this paper we proposed a Distributed Data E...

Developmental defects of enamel (DDE) are frequently observed in pediatric dental patients. Proper diagnosis may improve the clinician's dental care. The purpose of this article is to present the clinical management of some common dental defects: (1) hypoplasia; (2) diffuse and demarcated opacities; (3) fluorosis; (4) amelogenesis imperfecto (Al); and (5) dentinogenesis imperfecto (DI). The com...

During 1997 we evaluated reproductive success in colonial water birds nesting in the Lower Rio Grande Valley (LRGV), Texas, and correlated success with concentrations of contaminants in eggs. We also measured steroid hormones and gonadosomatic index (GSI) as biomarkers of endocrine effects in common carp (Cyprinus carpio). Nest and fledging success of green herons (Butorides virescens) and grea...

BACKGROUND Although it has been hypothesized that fetal exposure to endocrine-disrupting chemicals may increase obesity risk, empirical data are limited, and it is uncertain how early in life any effects may begin. OBJECTIVES We explored whether prenatal exposure to several organochlorine compounds (OCs) is associated with rapid growth in the first 6 months of life and body mass index (BMI) l...
