HALO - a Java framework for precise transcript half-life determination
UNLABELLED Recent improvements in experimental technologies now allow measurements of de novo transcription and/or RNA decay at whole transcriptome level and determination of precise transcript half-lives. Such transcript half-lives provide important insights into the regulation of biological processes and the relative contributions of RNA decay and de novo transcription to differential gene ex...
متن کاملHALF-LIFE DETERMINATION OF 41Ca AND SOME OTHER RADIOISOTOPES
We have performed a new determination of the half-life of 41Ca by measuring the specific activity of an enriched Ca material with known 41Ca abundance. We measured the activity via the 3.3-keV X-rays emitted in the electron capture decay of 41Ca, and the 41Ca abundance was measured by low-energy mass spectrometry. The result, t1a = (1.01 ± 0.10) x 10 yr, agrees with the recent `geological' half...
متن کاملThe half-life of 87Rb.
The half-life of 87Rb was measured by a liquid scintillation method according to the efficiency tracing method. The measuring sample of rubidium chloride was dissolved in a scintillation cocktail of Insta-gel, and the rubidium was determined by gravimetry as tetraphenylborate. The result was (5.56 +/- 0.025) x 10(10) years.

متن کاملHalf-Life Learning Curves in the Defense Acquisition Life Cycle
Learning curves are useful for assessing performance improvement due to the positive impact of learning. In recent years, the deleterious effects of forgetting have also been recognized. Workers experience forgetting or decline in performance over time. Consequently, contemporary learning curves have attempted to incorporate forgetting components into learning curves. An area of increasing inte...
