High-speed Internet connectivity, often referred to as " broadband, " supports a growing array of applications and services with significant potential to help older adults live more independent and meaningful lives. In fact,(More)
A proof-of-concept basic prediction framework able to read the PAN author profiling data and be adaptable to accept multiple classification and training functions. The framework was used to investigate system resource usage and to experiment with data sub-setting techniques to enable efficient creation of the base model and convergence of the training(More)
BACKGROUND Evidence of an association between serum vitamin D and cardiovascular disease risk is inconsistent and comes predominantly from studies in high-income settings. We assessed the association between serum levels of 25-hydroxyvitamin D3 (25(OH)D) and cardiovascular disease risk factors in a population of young Indian adults. METHODS(More)
