is the fraction of HEADS in X n = (X1, . . . , Xn). Since θ = Eθ̂n , (1) says that the sample (or empirical) average of the Xi ’s concentrates sharply around the statistical average θ = EX1. Bounds like these are fundamental in statistical learning theory. In the next few lectures, we will learn the techniques needed to derive such bounds for settings much more complicated than coin tossing. Thi...
Brahn (3) observed very low liver catalase ac tivity in human beings who had died as the result of malignant growths. Later work showed that of all the individual liver enzymes studied in can cerous rats and mice the activity of catalase was by far the most affected. Greenstein and co workers (6, 7) have reported that with the pro gressive growth of the tumor there is a decrease in liver catala...

Participants were exposed to a brief mindfulness intervention and subsequently performed a verbal learning test consisting of positive, neutral, and negative words. Control participants received no intervention ...
OF DISSERTATION
A synthesis procedure for heteroatom-substituted tetra(3,4-pyrido)porphyrazines that absorb light near 800 nm was developed. Based on the observed relationships between the structure and photophysical parameters, a novel highly photodynamically active (IC50 = 0.26 μM) compound was synthesized and biologically characterized.

OBJECTIVE This meta-analysis was conducted to investigate the effects of mindfulness-based stress reduction (MBSR) on the mental and physical health status of various cancer patients. METHODS Ten studies (randomized-controlled trials and observational studies) were found to be eligible for meta-analysis. Individual study results were categorized into mental and physical variables and Cohen's ...
