Anomaly (physics), a failure of a symmetry of a theory's classical action. Conformal anomaly, a quantum phenomenon that breaks the conformal symmetry of the classical theory. Chiral anomaly, an anomalous nonconservation of a chiral current. Gauge anomaly, the effect of quantum mechanics that invalidates the gauge symmetry of a quantum field theory.
Anomalistics is the use of scientific methods to evaluate anomalies (phenomena that fall outside current understanding), with the aim of finding a rational explanation. [1] The term itself was coined in 1973 by Drew University anthropologist Roger W. Wescott, who defined it as being the "serious and systematic study of all phenomena that fail ...
v. t. e. In data analysis, anomaly detection (also referred to as outlier detection and sometimes as novelty detection) is generally understood to be the identification of rare items, events or observations which deviate significantly from the majority of the data and do not conform to a well defined notion of normal behavior. [1]
Total anomalous pulmonary venous connection, also known as total anomalous pulmonary venous return, is a rare cyanotic congenital heart defect in which all four pulmonary veins are malpositioned and make anomalous connections to the systemic venous circulation. A right-to-left shunt such as a patent foramen ovale, patent ductus arteriosus or an ...
A few verbs are regular in their spoken forms, but have irregular spelling. The irregular weak verbs (being in normal use) can consequently be grouped as follows: Verbs with vowel shortening: creep, flee, hear, keep, leap, shoe (when shod is used), sleep, sweep and weep. (Of these, creep, flee, leap, sleep and weep derive from verbs that were ...
In statistics, an outlier is a data point that differs significantly from other observations. [1][2] An outlier may be due to a variability in the measurement, an indication of novel data, or it may be the result of experimental error; the latter are sometimes excluded from the data set. [3][4] An outlier can be an indication of exciting ...
The phrase "Anomalistic Psychology" was a term first suggested by the psychologists Leonard Zusne and Warren Jones in their book Anomalistic Psychology: A Study of Magical Thinking (1989) which systematically addresses phenomena of human consciousness and behaviors that may appear to violate the laws of nature when they actually do not.
Apparitional experiences. A common type of anomalous experience is the apparitional experience, which may be defined as one in which a subject seems to perceive some person or thing that is not physically present. Self-selected samples tend to report a predominance of human figures, but apparitions of animals, [5] and even objects [6] are also ...
