Then is called a pivotal quantity (or simply a pivot). Pivotal quantities are commonly used for normalization to allow data from different data sets to be compared. It is relatively easy to construct pivots for location and scale parameters: for the former we form differences so that location cancels, for the latter ratios so that scale cancels.
Transcription factors are one of the groups of proteins that read and interpret the genetic "blueprint" in the DNA. They bind to the DNA and help initiate a program of increased or decreased gene transcription. As such, they are vital for many important cellular processes.
A sigma factor (σ factor or specificity factor) is a protein needed for initiation of transcription in bacteria. [1] [2] It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase (RNAP) to gene promoters. It is homologous to archaeal transcription factor B and to eukaryotic factor TFIIB. [3]
NF-κB is a major transcription factor that regulates genes responsible for both the innate and adaptive immune response. [52] Upon activation of either the T- or B-cell receptor , NF-κB becomes activated through distinct signaling components.
The Pareto principle may apply to fundraising, i.e. 20% of the donors contributing towards 80% of the total. The Pareto principle (also known as the 80/20 rule, the law of the vital few and the principle of factor sparsity [1] [2]) states that for many outcomes, roughly 80% of consequences come from 20% of causes (the "vital few").

GAINESVILLE — The Florida Gators’ home game against Arkansas isn’t their biggest of the season. It can’t top the win over Tennessee or the magnitude of last week’s loss to No. 1 Georgia.
For those who are feeling “stuck" or overwhelmed while striving for work-life balance, some experts recommend adopting a “pendulum lifestyle." Psychologists weigh in on the potential benefits.
