In finance the put/call ratio (or put-call ratio, PCR) is a technical indicator demonstrating investor sentiment. [1] The ratio represents a proportion between all the put options and all the call options purchased on any given day. The put/call ratio can be calculated for any individual stock, as well as for any index, or can be aggregated. [2]
A real-time polymerase chain reaction (real-time PCR, or qPCR when used quantitatively) is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR). It monitors the amplification of a targeted DNA molecule during the PCR (i.e., in real time), not at its end, as in conventional PCR.
The maximum allowable rate at which cells can be transported along a connection in the ATM network. The PCR is the determining factor in how often cells are sent in relation to time in an effort to minimize jitter. PCR generally is coupled with the CDVT (Cell Delay Variation Tolerance), which indicates how much jitter is allowable.
In statistics, principal component regression (PCR) is a regression analysis technique that is based on principal component analysis (PCA). PCR is a form of reduced rank regression. [1] More specifically, PCR is used for estimating the unknown regression coefficients in a standard linear regression model.
The PCR products are quantified, typically by (capillary) electrophoresis. Each probe pair consists of two oligonucleotides, with sequence that recognizes adjacent sites of the target DNA , a PCR priming site, and optionally a "stuffer" to give the PCR product a unique length when compared to other probe pairs in the MLPA assay.
Phosphocreatine, also known as creatine phosphate (CP) or PCr (Pcr), is a phosphorylated form of creatine that serves as a rapidly mobilizable reserve of high-energy phosphates in skeletal muscle, myocardium and the brain to recycle adenosine triphosphate, the energy currency of the cell.
Here's what causes food poisoning, when you should be worried and what can be done to prevent having to experience it in the first place.
AmpFLP was the first attempt to couple VNTR analysis with PCR for forensic casework. This method used shorter VNTRs than RFLP analysis, between 8 and 16 base pairs. The shorter base pair sizes of AmpFLP was designed to work better with the amplification process of PCR. [8]
