Jaundice The medical term for it is "icterus", from the Greek word "ίκτερος"; adjectival form, icteric. Jaundice Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and whites of the eyes due to high bilirubin levels. It is commonly associated with itchiness. The feces may be pale and the urine dark. Jaundice in babies occurs in over half in the first week following birth and in most is not a problem. If bilirubin levels in babies are very high for too long, a type of brain damage, known as kernicterus, may occur. Causes of jaundice vary
Sommerfeld radiation condition The other solutions are unphysical. For example, formula_23 can be interpreted as energy coming from infinity and sinking at formula_22 Sommerfeld radiation condition Arnold Sommerfeld defined the condition of radiation for a scalar field satisfying the Helmholtz equation as Mathematically, consider the inhomogeneous Helmholtz equation where formula_2 is the dimension of the space, formula_3 is a given function with compact support representing a bounded source of energy, and formula_4 is a constant, called the "wavenumber". A solution formula_5 to this equation is called "radiating" if it satisfies the Sommerfeld radiation condition uniformly in all directions (above, formula_8 is the imaginary
