One of the long-standing problems in antenna engineering is the realization of highly directive beams using low-profile devices. In this paper, we provide a solution to this problem by means of Huygens' metasurfaces (HMSs), based on the equivalence principle. This principle states that a given excitation can be transformed to a desirable aperture field by inducing suitable electric and (equival...

An aerobic endospore-forming bacterium, tentatively identified as a strain (JJ-lb) of Bacillus macerans, was isolated by enrichment on 4-hydroxybenzoate (4HBA), using as an inoculum soil taken from a 50 degrees C Iadho hot spring. Enzymatic analyses of cells grown on succinate and 4HBA indicated that strain JJ-1b degrades 4HBA by way of the novel protocatechuate (PCA) 2,3-dioxygenase pathway. P...

The present study is an attempt to assess the impacts of climate change on water resources of the river basins of India which have immense importance in domestic, industrial agricultural and hydropower scenario. A distributed hydrological model developed from HEC-HMS was used on the Indian river basins using the projected daily precipitation and temperature data for the continuous daily range f...

INTRODUCTION Telehealth has been widely promoted as a technology to make healthcare more effective and affordable. However, current telehealth systems suffer from vendor lock-in and high cost, and are designed for managing chronic diseases rather than preventing them. METHODS We address shortcomings of existing consumer-level health informatics applications in supporting senior health consume...

Introduction BioSense 2.0, a redesigned national syndromic surveillance system, provides users with timely regional and national data classified into disease syndromes, with views of health outcomes and trends for use in situational awareness. As of July 2014, there are 60 jurisdictions nationwide feeding data into BioSense 2.0. In New Jersey, the state’s syndromic surveillance system, EpiCente...

(S)-Hydroxymandelate synthase (Hms) is a nonheme Fe(II) dependent dioxygenase that catalyzes the oxidation of 4-hydroxyphenylpyruvate to (S)-4-hydroxymandelate by molecular oxygen. In this work, the substrate promiscuity of Hms is characterized in order to assess its potential for the biosynthesis of chiral α-hydroxy acids. Enzyme kinetic analyses, the characterization of product spectra, quant...

Floods have become more severe and frequent as a result of climate change around the world, posing hazard to public safety economic development. This study investigates use distributed hydrological models in flash flood risk management small watershed Hazara, Pakistan, with goal improving Pakistan's early warning lead time. First, HEC-HMS model was built using geographic data river network's st...

Herein, an efficient and practical approach for dipolar modification of commercially available solid catalysts is reported. The HMS (hexagonal mesoporous silica)-DMSO decorated with organic layers are designed synthesized by radiation technology under simple accessible conditions. can serve as platforms to introduce various active sites, benefiting from the flexibility diversity layer, which in...

Hybrid male sterility (HMS) is a rapidly evolving mechanism of reproductive isolation in Drosophila. Here we report a genetic analysis of HMS in third-chromosome segments of Drosophila mauritiana that were introgressed into a D. simulans background. Qualitative genetic mapping was used to localize 10 loci on 3R and a quantitative trait locus (QTL) procedure (multiple-interval mapping) was used ...
