A need for better vitamin nutrition appears at three levels: vitamin insufficiency, deficiency, and dependence. A vitamin insufficiency requires the body to make some degree of metabolic adjustment because the amount of the coenzyme (vitamin) is limited. Myofascial pain syndromes are aggravated by insufficient levels of at least four Bcomplex vitamins as listed above. Vitamin deficiency, on the...

Ultrasound is a medical diagnostic technique that uses sound waves to produce images of the inside of the body. During the early 1900s, physicians had no way to see inside a woman?s uterus [5] during pregnancy [6]. Donald developed the first method of scanning human internal anato...

Stochastic Discrete Clenshaw-Curtis Quadrature

The partition function is fundamental for probabilistic graphical models—it is required for inference, parameter estimation, and model selection. Evaluating this function corresponds to discrete integration, namely a weighted sum over an exponentially large set. This task quickly becomes intractable as the dimensionality of the problem increases. We propose an approximation scheme that, for any...
