Once quantitative counts of each transcript are available, differential gene expression is measured by normalising, modelling, and statistically analysing the data. [108] Most tools will read a table of genes and read counts as their input, but some programs, such as cuffdiff, will accept binary alignment map format read alignments as input.
The objective of quantitative research is to develop and employ mathematical models, theories, and hypotheses pertaining to phenomena. The process of measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships.

The STEM strand is under the Academic Track, which also includes other strands like ABM, HUMSS, and GAS. [60] [61] The purpose of the STEM strand is to educate students in the field of science, technology, engineering, and mathematics, in an interdisciplinary and applied approach, and to give students advanced knowledge and application in the ...

Electron microscopy has accelerated research in materials science by quantifying properties and features from nanometer-resolution imaging with STEM, which is crucial in observing and confirming factors, such as thin film deposition, crystal growth, surface structure formation, and dislocation movement.
The immortal DNA strand hypothesis was proposed in 1975 by John Cairns as a mechanism for adult stem cells to minimize mutations in their genomes. [1] This hypothesis proposes that instead of segregating their DNA during mitosis in a random manner, adult stem cells divide their DNA asymmetrically, and retain a distinct template set of DNA strands (parental strands) in each division.
Over 30 publications exist describing its use first for nucleosome positioning from Valouev et al., [1] transcriptional profiling or strand sensitive RNA-Seq with Cloonan et al., [2] single cell transcriptional profiling with Tang et al. [3] and ultimately human resequencing with McKernan et al. [4]
