[1] Time-lapse geophysical measurements are widely used to monitor the movement of water and solutes through the subsurface. Yet commonly used deterministic least squares inversions typically suffer from relatively poor mass recovery, spread overestimation, and limited ability to appropriately estimate nonlinear model uncertainty. We describe herein a novel inversion methodology designed to rec...
The fate of organic carbon deposited in floodplain sediments is an important control on the magnitude and direction flux from anthropogenically accelerated erosion channelization riverine network. Globally, deposition rates mean residence time (MRT) within different geomorphic settings remains poorly constrained. We sampled soil profiles to 0.8 m depth two zones: active channel belt (ACB) lowla...
We investigate the effects of noise on controlled-source interferometry by multi-dimensional deconvolution (MDD) for diffusive electromagnetic (EM) fields and for seismic wavefields. An electromagnetic and a seismic dataset are modeled and decomposed into upand downwards decaying and upand downgoing fields, respectively. From the decomposed fields a reflection response can be retrieved using le...
We reported previously that subsets of nucleus accumbens (Acb) neurons differentially encode information about goal-directed behaviors for "natural" (food and water) versus cocaine reward in animals well trained to self-administer the drug (Carelli et al., 2000). Here, we examined whether repeated exposure to cocaine is the crucial determinate of the selective encoding of cocaine versus water r...
OBJECTIVE Acinetobacter baumannii is a worldwide nosocomial pathogen that has become increasingly common over the past few decades, and strains of multidrug-resistant A. baumannii have been increasing. The aim of this study was to assess the clinical characteristics of A. calcoaceticus-A. baumannii complex (Acb complex) strains and to determine the risk factors of this infection. METHODS The ...
Cerebral palsy (CP) is a condition affecting young children that causes lifelong disabilities. Umbilical cord blood cells improve motor function in experimental systems via paracrine signaling. After demonstrating safety, we conducted a phase II trial of autologous cord blood (ACB) infusion in children with CP to test whether ACB could improve function (ClinicalTrials.gov, NCT01147653; IND 1436...
a simple and rapid method for the determination of 137ba isotope abundances in water samples by inductively coupled plasma-optical emission spectrometry (icp-oes) coupled with least-squares support vector machine regression (ls-svm) is reported. by evaluation of emission lines of barium, it was found that the emission line at 493.408 nm provides the best results for the determination of 137ba a...
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
Digital super resolution is a term used to describe the inverse problem of reconstructing a high resolution image from a set of known low resolution images, each of which is shifted by subpixel displacements. Simple models assume the subpixel displacements are known, but if the displacements are not known, then nonlinear approaches must be used to jointly find the displacements and the reconstr...
