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]
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 ...
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
This article is a list of notable unsolved problems in astronomy.Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results.
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).
A teen actor, whose credits include the 2017 film Baby Driver and the reboot of the television action series MacGyver, died after he reportedly fell from a moving vehicle in Alabama last week ...
The most notable answers might have been the shortest, when a reporter brought up Jets owner Woody Johnson: Reporter: Do you think Woody wants you back? Rodgers: You should ask Woody.
A special case of this problem is known as the “counting anomaly”. [ 32 ] [ 33 ] Supporters of collapse theories mostly dismiss this criticism as a misunderstanding of the theory, [ 34 ] [ 35 ] as in the context of dynamical collapse theories, the absolute square of the wave function is interpreted as an actual matter density.
