Amplified fragment length polymorphism (AFLP-PCR or AFLP) is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by Pieter Vos, [ 1 ] AFLP uses restriction enzymes to digest genomic DNA , followed by ligation of adaptors to the sticky ends of the restriction ...
There is no assessment of executive function, phonemic fluency, or motor responses. It takes about half an hour to administer. [ 3 ] It was originally introduced in the screening for dementia , but has also found application in other situations, [ 3 ] such as hepatic encephalopathy .
The Innovator's Dilemma: When New Technologies Cause Great Firms to Fail, first published in 1997, is the best-known work of the Harvard professor and businessman Clayton Christensen. It expands on the concept of disruptive technologies , a term he coined in a 1995 article "Disruptive Technologies: Catching the Wave". [ 1 ]
Additional research proposes the notion of a moveable filter. The multimode theory of attention combines physical and semantic inputs into one theory. Within this model, attention is assumed to be flexible, allowing different depths of perceptual analysis. [28] Which feature gathers awareness is dependent upon the person's needs at the time. [3]

This test purports to "provide a nonverbal measure of general intelligence by sampling a wide variety of functions from memory to nonverbal reasoning." [ 1 ] A remarkable feature of the Leiter scale is that it can be administered completely without the use of oral language, including instructions, and requires no verbal response from the ...
The CDR system (The CDR system) is a computerized battery of cognitive tests designed in the late 1970s by Professor Keith Wesnes at the University of Reading in Berkshire, England, for repeated testing in clinical trials.
DNA and RNA alignments may use a scoring matrix, but in practice often simply assign a positive match score, a negative mismatch score, and a negative gap penalty. (In standard dynamic programming, the score of each amino acid position is independent of the identity of its neighbors, and therefore base stacking effects are not taken into account.
