The Physician and Sportsmedicine: Myths and Truths of Stretching

In Brief: Stretching recommendations are clouded by misconceptions and conflicting research reports. This review of the current literature on stretching and range-of-motion increases finds that one static stretch of 15 to 30 seconds per day is sufficient for most patients, but some require longer durations. Heat and ice improve the effectiveness of static stretching only if applied during the s...

Myths and Truths Concerning Estimation of Power Spectra

It is widely believed that maximum likelihood estimators must be used to provide optimal estimates of power spectra. Since such estimators require the inversion and multiplication of Nd×Nd matrices, where Nd is the size of the data vector, maximum likelihood estimators require of order N d operations and become computationally prohibitive for Nd greater than a few tens of thousands. Because of ...

The Myths (and Truths) of Java Games Programming

This paper examines the commonly-expressed criticisms of Java as a games programming language: that's it's too slow, too high-level, prone to memory problems, too hard to install, not available on games consoles, not used in 'real' games, and not even considered a gaming platform by Sun Microsystems. All of these views are incorrect, aside from the console issue.

Controlled-rate freezing of human ES cells.

A significant obstacle to using human embryonic stem cells (hESCs) arises from extremely poor survival associated with freezing, typically in the range of 1%. This report describes a slow controlled-rate freezing technique commonly used for mammalian embryo cryopreservation. Using a combination of surviving colony number and colony diameter; survival was determined relative to untreated hESCs. ...
