Databases of commercial DNA-testing companies now contain more customers with sequenced DNA than any completed academic study, leading to growing interest from and forensic entities. An important result for both these entities the test takers themselves is how closely two individuals are related in time, as calculated through one or molecular clocks. For Y-DNA, existing interpretations clocks i...

The neural network learning process is a sequence of network updates and can be represented b y sequence of points in the weight space that we call a learning trajectory. In this paper a new learning approach based on repetitive bounded depth trajectory branching M proposed. This approach has objectives of improving generalization and speeding up Convergence b y avoiding local minima when selec...

Grandiose, quaint, eccentric or homey, ceiling design statements go a long way toward creating the look and feel desired for a commercial or institutional interior. The key to enhancing building performance, however, is balancing aesthetic appeal with effective acoustics, improved sustainability, and smart integration of mechanical, electrical, and plumbing equipment. Fortunately, the marketpla...

M e t h o d s Data sources: Reference lists of previous systematic reviews, MEDLINE, EMBASE/ Excerpta Medica, Cancerlit, and lists of conference abstracts (1980 to 2006). Study selection and assessment: English-language randomized controlled trials (RCTs) that compared neoadjuvant chemoradiotherapy or chemotherapy followed by surgery with surgery alone in the initial management of operable esop...

Interferon gamma (IFN y) has been advocated in open studies as a beneficial remission inducing drug for the treatment of rheumatoid arthritis (RA). The work reported here was designed to assess the therapeutic potential of IFN y in the treatment of RA in a double blind placebo controlied study. It was found that patients treated with IFN y improved significantly with respect to morning stiffnes...

This case study observed the training delivered by a 1500-m runner and the physiological and performance change during a 2-y period. A male international 1500-m runner (personal best 3:38.9 min:s, age 26 y, height 1.86 m, body mass 76 kg) completed 6 laboratory tests and 14 monitored training sessions, during 2 training years. Training distribution and volume was ascertained from training diary...

A convergence result for a generalized Richardson extrapolation process is improved upon considerably and additional results of interest are proved. An application of practical importance is also given. Finally, some known results concerning the convergence of Levin's T-transformation are reconsidered in light of the results of the present work. Let A(y) be a scalar function of a discrete or co...

Before the advent of tomographic imaging, it was postulated that decay of (90) Y to the 0(+) excited state of (90)Zr may result in emission of a positron-electron pair. While the branching ratio for pair-production is small (~32 × 10(-6)), PET has been successfully used to image (90) Y in numerous recent patients and phantom studies. (90) Y PET imaging has been performed on a variety of PET/CT ...
