During the last decade Ground Penetrating Radar (GPR) has proved its ability to act as a powerful geophysical tool for subsurface investigations. GPR is a more user friendly and cost-effective tool due to recent technological developments. Lower cost and simple operation has increased the practice of GPR in the utility locating market as well as other traditional markets. Deploying GPR methods ...

We examine the effect of a health plan's pay for performance incentives on the percentage of outpatient drug prescriptions that are filled with generic rather than brand-name drugs in physicians' practices in an established physician network - the generic prescription rate (GPR). The financial reward was based on the performance of the entire network, but the network implemented rewards at the ...

BACKGROUND Several hepatic cirrhosis-derived noninvasive models have been developed to predict the incidence and outcomes of hepatocellular carcinoma (HCC). We aimed to investigate the prognostic significance of the two novel established cirrhosis-associated models based on gamma-glutamyl transpeptidase (GGT) and platelets in hepatitis B-associated HCC. METHODS We retrospectively evaluated 18...

Geophysical methods are important tools for a wide range of geological, hydrogeological, and engineering investigations. Conventional processing techniques for electromagnetic tools often use approximations that may be either inappropriate or only provide limited resolution. Higher resolution images can be derived by using more sophisticated approaches that explicitly take into account the elec...

Continuous emotion recognition (CER) is a task which requires the prediction of time series emotional parameter outputs corresponding to query time series inputs given training data in the form of matched pairs of input and output time series. In order to address this task, it is important to be able to model not only relationships between points in the input and output spaces, but also tempora...

Gaussian process regression (GPR) is a non-parametric Bayesian technique for interpolating or fitting data. The main barrier to further uptake of this powerful tool rests in the computational costs associated with the matrices which arise when dealing with large datasets. Here, we derive some simple results which we have found useful for speeding up the learning stage in the GPR algorithm, and ...

Most Ground Penetrating Radar (GPR) measurements are performed on nearly flat areas. If strongly dipping reflections and/or diffractions are present in the GPR data, a classical migration processing step is needed in order to determine the geometries of shallow structures. Nevertheless, a standard migration routine is not suitable for GPR data collected on areas showing a variable and large top...

In adults, glucose infusion results in a decreased glucose production rate (GPR) as a mechanism for maintaining euglycemia. To document the development of glucose homeostasis, we derived the GPR in 23 preterm appropriate for gestational age infants, 14 term appropriate for gestational age infants, and in 6 adults. After a 3-h fast, the average plasma glucose and insulin concentration was measur...

Ground-penetrating radar (GPR) has recently gained a wide acceptance in the archaeological community as a method to quickly and accurately locate buried archaeological features, artifacts, and important cultural and geological strata in the near-surface. The GPR method has now become one of the primary tools for geophysical feature identification primarily because of its three-dimensional abili...
