Assessing program quality and outcomes is essential to improve postgraduate dental education. This study's aims were to document career direction and practice patterns of graduates of the Brigham and Women's Hospital (BWH) General Practice Residency (GPR), to compare BWH GPR outcomes to those of other American GPRs, and to identify characteristics of the BWH GPR program that trainees valued. Th...

Ground-penetrating radar GPR attenuation-difference tomography is a useful tool for imaging the migration of electrically anomalous tracer or contaminant plumes. Attenuation-difference tomography uses the difference in the trace amplitudes of tomographic data sets collected at different times to image the distribution of bulk-conductivity changes within the medium. The most common approach for ...

Ground Penetrating Radar (GPR) is an effective and practical geophysical imaging tool, with a wide set of applications in geological mapping of subsurface information. This research study aims at determination of the geophysical parameter differences in the subsurface geological structures and construction of a 3D fracture model. GPR and resistivity methods were applied to detect the unstable t...

Abstract Ballast fouling in railroad substructure is detrimental to railroad track effectiveness and its structural capacity. Ground penetrating radar (GPR) provides a rapid, effective and continuous approach to assess railroad substructure condition. However, unknown ballast dielectric constant and unclear interface between clean and fouled ballast limit the GPR assessment accuracy. In this st...

Subsidence seriously affects the structural stability and safety of pavements foundation soils. In heavy-loaded pavements, there is a risk floor sinking further construction collapse; hence, need to develop efficient methodologies detect subsidence earlier. This work proposes use ground penetrating radar (GPR) as solution non-invasively inspect subsoil. Furthermore, interpretation GPR data argu...

Functional meaning of oscillatory brain activity in various frequency bands in the human electroencephalogram (EEG) is increasingly researched. While most research focuses on event-related changes of brain activity in response to external events there is also increasing interest in internal brain states influencing information processing. Several studies suggest amplitude changes of EEG oscilla...

BACKGROUND Support vector regression (SVR) and Gaussian process regression (GPR) were used for the analysis of electroanalytical experimental data to estimate diffusion coefficients. RESULTS For simulated cyclic voltammograms based on the EC, Eqr, and EqrC mechanisms these regression algorithms in combination with nonlinear kernel/covariance functions yielded diffusion coefficients with highe...
