Shone’s syndrome is a rare disorder that is often detected in very young children. The children tend to show symptoms like fatigue, nocturnal cough, and reduced cardiac output by the age of two years. They also develop wheezing due to the exudation of fluid into the lungs. [1]
Congenital heart anomaly, congenital heart disease: The normal structure of the heart (left) in comparison to two common locations for a ventricular septal defect (right), the most common form of congenital heart defect [1] Specialty: Cardiology: Symptoms: Rapid breathing, bluish skin, poor weight gain, feeling tired [2] Complications: Heart ...

A conformal anomaly, scale anomaly, trace anomaly or Weyl anomaly is an anomaly, i.e. a quantum phenomenon that breaks the conformal symmetry of the classical theory.. In quantum field theory when we set to zero we have only Feynman tree diagrams, which is a "classical" theory (equivalent to the Fredholm formulation of a classical field theory).
In string theory, modular invariance is an additional requirement for one-loop diagrams. This helps in getting rid of some global anomalies such as the gravitational anomalies . Equivalently, in two-dimensional conformal field theory the torus partition function must be invariant under the modular group SL(2,Z) .
BRST quantization is a differential geometric approach to performing consistent, anomaly-free perturbative calculations in a non-abelian gauge theory. The analytical form of the BRST "transformation" and its relevance to renormalization and anomaly cancellation were described by Carlo Maria Becchi, Alain Rouet, and Raymond Stora in a series of papers culminating in the 1976 "Renormalization of ...
John Gall (September 18, 1925 – December 15, 2014) was an American author, scholar, and pediatrician. [1] [2] Gall is known for his 1975 book General systemantics: an essay on how systems work, and especially how they fail..., a critique of systems theory.
Lysander Spooner (January 19, 1808 — May 14, 1887) was an American abolitionist, entrepreneur, lawyer, essayist, natural rights legal theorist, pamphletist, political philosopher, and writer often associated with the Boston anarchist tradition.
