Three examples of Turing patterns Six stable states from Turing equations, the last one forms Turing patterns. The Turing pattern is a concept introduced by English mathematician Alan Turing in a 1952 paper titled "The Chemical Basis of Morphogenesis" which describes how patterns in nature, such as stripes and spots, can arise naturally and autonomously from a homogeneous, uniform state.
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically . Natural patterns include symmetries , trees , spirals , meanders , waves , foams , tessellations , cracks and stripes. [ 1 ]
EVI1 expression in humans does not directly influence fingerprint patterns but does affect limb and digit formation which in turn may play a role in influencing fingerprint patterns. [22] Genome-wide association studies found single nucleotide polymorphisms within the gene ADAMTS9-AS2 on 3p14.1, which appeared to have an influence on the whorl ...
A whorl (/ w ɜːr l / or / w ɔːr l /) is an individual circle, oval, volution or equivalent in a whorled pattern, which consists of a spiral or multiple concentric objects (including circles, ovals and arcs).

Dermatoglyphics, when correlated with genetic abnormalities, aids in the diagnosis of congenital malformations at birth or soon after.. Klinefelter syndrome: excess of arches on digit 1, more frequent ulnar loops on digit 2, overall fewer whorls, lower ridge counts for loops and whorls as compared with controls, and significant reduction of the total finger ridge count.
However, there can be no doubt that Faulds' first paper on the subject was published in the scientific journal Nature in 1880; all parties conceded this. The following month Sir William Herschel, a British civil servant based in India, wrote to Nature saying that he had been using fingerprints (as a form of bar code) to identify criminals since ...
The Henry Classification System is a long-standing method by which fingerprints are sorted by physiological characteristics for one-to-many searching. Developed by Hem Chandra Bose, [1] Qazi Azizul Haque [2] and Sir Edward Henry in the late 19th century for criminal investigations in British India, [3] it was the basis of modern-day AFIS (Automated Fingerprint Identification System ...
