The SSA+ for scattering from dielectric surfaces at very low grazing angles
(Taylor and Francis, 2011-02)
In this paper we develop an extension of the small slope approximation (SSA) for scattering from randomly rough Dirichlet surfaces, which includes some multiple scattering. This extension is designated by SSA+. We focus ...
A numerical study of conjugate gradient directions for an ultrasound inverse problem
(World Scientific Publishing, 2004-12)
In ultrasound inverse problems, the integral equation can be nonlinear, ill-posed, and computationally expensive. One approach to solving such problems is the conjugate gradient (CG) method. A key parameter in the CG method ...
A practical cross section for scattering from rough surfaces at very low grazing angles in both the forward and backward directions
(Taylor and Francis, 2009-08)
In this paper we develop an extension of the small slope approximation (SSA) for scattering from randomly rough Dirichlet surfaces, which includes some multiple scattering. This extension is designated by SSA+. We focus ...
A Java-based tool for the design of classification microarrays
(Oxford University Press, 2008-08)
Classification microarrays are used for purposes such as identifying strains of bacteria and determining genetic relationships to understand the epidemiology of an infectious disease. For these cases, mixed microarrays, ...
A conjugate gradient-neural network technique for ultrasound inverse imaging
(World Scientific Publishing, 2002-06)
In this paper, a new technique for solving the two-dimensional inverse scattering problem for ultrasound inverse imaging is presented. Reconstruction of a two-dimensional object is accomplished using an iterative algorithm ...
Identification of Anaplasma marginale type IV secretion system effector proteins
(PLoS ONE, 2011-11)
Anaplasma marginale, an obligate intracellular alphaproteobacterium in the order Rickettsiales, is a tick-borne pathogen and the leading cause of anaplasmosis in cattle worldwide. Complete genome sequencing of A. marginale ...
ApicoAP: The first computational model for predicting apicoplast-targeted proteins for multiple species of Apicomplexa
(PLoS ONE, 2012-05)
Most of the parasites of the phylum Apicomplexa contain a relict prokaryotic-derived plastid called the apicoplast. This organelle is important not only for the survival of the parasite, but its unique properties make it ...
BlaCMY-2 positive Inc A/C plasmids from Escherichia coli and Salmonella enterica are a distinct component of a larger lineage of plasmids
(Antimicrobial Agents and Chemotherapy, 2009-11)
Large multidrug resistance plasmids of the A/C incompatibility complex (IncA/C) have been found in a diverse group of Gram-negative commensal and pathogenic bacteria. We present three completed sequences from IncA/C plasmids ...
Genotypic-phenotypic discrepancies between antibiotic resistance characteristics of Escherichia coli from calves in high and low antibiotic use management settings
(Applied and Environmental Microbiology, 2011-05)
We hypothesized that bacterial populations growing in the absence of antibiotics will accumulate more resistance gene mutations than bacterial populations growing in the presence of antibiotics. If this is so, the prevalence ...
Validation of mixed-genome microarrays as a method for genetic discrimination
(Applied and Environmental Microbiology, 2007-03)
Comparative genomic hybridizations have been used to examine genetic relationships among bacteria. The microarrays used in these experiments may have open reading frames from one or more reference strains (whole-genome ...
