At times, leaping from one patient management routine to an alternative one may be required to mitigate medical errors. "Frozen patient management" is the resultant situation, when, in the face of an obvious gap between the expected and the actual phenomena, leaping from current patient management to an alternative one is not considered or done. Frozen patient management can lead to a significa...

Modernizing a classic technique to study microtubules has revealed that the stability of a microtubule is related to its growth rate.

A Reliability Odometer - Lemon Check Your Processor!

Guaranteeing long processor lifetimes by limiting the on-set of wear-out or hard failures is a critical requirement for all processor manufacturers [3, 4]. In addition, lifetime predictability is also crucial from the point of view of service replacements, avoiding down-time, etc. This is particularly true for vendors of high-end servers where predictable reliability is an implicit requirement....

Using SAS® Software to Check Assumptions for Analysis

Analysis of covariance (ANCOVA) is a powerful statistical tool for adjusting an analysis to acoount for the effects of concomitant variables. The technique may be applied to completely randomized designs (CRO) as well as repeated measures designs. In addition to normality assumptions, ANCOVA depends on assumptions about variances and slopes. Although not usually provided directly, most statisti...
