Shone's syndrome is a rare congenital heart defect described by Shone in 1963. In the complete form, four left-sided defects are present: [1] Supravalvular mitral membrane (SVMM) Parachute mitral valve; Subaortic stenosis (membranous or muscular) Coarctation of the aorta
Rare Earth was succeeded in 2003 by the follow-on book The Life and Death of Planet Earth: How the New Science of Astrobiology Charts the Ultimate Fate of our World, also by Ward and Brownlee, which talks about the Earth's long-term future and eventual demise under a warming and expanding Sun, showing readers the concept that planets like Earth ...
Carroll has worked on a number of areas of theoretical cosmology, field theory and gravitation theory. His research papers include models of, and experimental constraints on, violations of Lorentz invariance; the appearance of closed timelike curves in general relativity; varieties of topological defects in field theory; and cosmological dynamics of extra spacetime dimensions.
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).
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 ...
Anomaly is a 2013 dystopian science-fiction Christian trilogy by Krista McGee, published through Thomas Nelson. The first book in the series, Anomaly , was published on July 9, 2013. The series's second entry, Luminary , was published on January 7, 2014.
In 2017, C R Moore and others reported a Pt anomaly at eleven continental sites dated to the Younger Dryas, which is linked with the Greenland Platinum anomaly. [118] In 2018, dealing with an "extraordinary biomass-burning episode" associated with the Younger Dryas Impact were reported by Wolbach and others [119] [120] and Lynch. [121]
Consequently, a planar Yang–Mills theory denotes a theory in the large N limit, with N usually the number of colors. Likewise, a planar limit is a limit in which scattering amplitudes are dominated by Feynman diagrams which can be given the structure of planar graphs. [ 11 ]
