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
Krein's condition Krein's condition In mathematical analysis, Krein's condition provides a necessary and sufficient condition for exponential sums to be dense in a weighted L space on the real line. It was discovered by Mark Krein in the 1940s. A corollary, also called Krein's condition, provides a sufficient condition for the indeterminacy of the moment problem. Let "μ" be an absolutely continuous measure on the real line, d"μ"("x") = "f"("x") d"x". The exponential sums are dense in "L"("μ") if and only if Let "μ" be as above; assume that all the moments of "μ" are finite. If holds, then the Hamburger moment
