In Windows 8 and 8.1, the ability to change the desktop wallpaper is still possible, however changing the Start screen color & design and lock screen wallpaper are disabled. Notifications also appear occasionally telling the user to activate. However, the operating system otherwise functions normally. [19]
The activation function of a node in an artificial neural network is a function that calculates the output of the node based on its individual inputs and their weights. Nontrivial problems can be solved using only a few nodes if the activation function is nonlinear .
Activator may refer to: Activator (genetics), a DNA-binding protein that regulates one or more genes by increasing the rate of transcription; Activator (phosphor), a type of dopant used in phosphors and scintillators; Enzyme activator, a type of effector that increases the rate of enzyme mediated reactions
A transcriptional activator is a protein (transcription factor) that increases transcription of a gene or set of genes. [1] Activators are considered to have positive control over gene expression, as they function to promote gene transcription and, in some cases, are required for the transcription of genes to occur.
It is an isozyme of hexokinase and is found mainly in pancreatic β cells, but also liver, gut, and brain cells where glycolysis cause glucose-induced insulin secretion. [2] Glucokinase activator lowers blood glucose concentrations by enhancing glucose uptake in the liver and increasing insulin production by the pancreatic β cells. [2]
The reaction it catalyzes is: pyruvate + HCO − 3 + ATP → oxaloacetate + ADP + P. It is an important anaplerotic reaction that creates oxaloacetate from pyruvate. PC contains a biotin prosthetic group [1] and is typically localized to the mitochondria in eukaryotes with exceptions to some fungal species such as Aspergillus nidulans which have a cytosolic PC.
The VP64-p65-Rta, or VPR, dCas9 activator was created by modifying an existing dCas9 activator, in which a Vp64 transcriptional activator is joined to the C terminus of dCas9. [1] In the dCas9-VPR protein, the transcription factors p65 and Rta are added to the C terminus of dCas9-Vp64.
It was released to manufacturing on August 1, 2012, made available for download via MSDN and TechNet on August 15, 2012, [6] and generally released for retail on October 26, 2012. [ 7 ] Windows 8 introduced major changes to the operating system's platform and user interface with the intention to improve its user experience on tablets , where ...
