A possible resolution of the information loss paradox for black holes is proposed in which a phase transition occurs when the temperature of an evaporating black hole equals a critical value, Tc, and Lorentz invariance and diffeomorphism invariance are spontaneously broken. This allows a generalization of Schrödinger’s equation for the quantum mechanical density matrix, such that a pure state c...

To elucidate the genes involved in the formation of white and black plumage in ducks, RNA from white and black feather bulbs of an F(2) population were analyzed using RNA-Seq. A total of 2,642 expressed sequence tags showed significant differential expression between white and black feather bulbs. Among these tags, 186 matched 133 annotated genes that grouped into 94 pathways. A number of genes...

This paper addresses the problem of rising Black/White disparities in imprisonment and seeks to determine factors predicting which states will have the highest Black imprisonment rates for various offenses. Annual state imprisonment rates for 1983-1999 are calculated from the Correctional Populations of the United States (CPUS) and National Corrections Reporting Program (NCRP) data. Dependent v...

This study assesses the effect of black-white differences in school quality on black-white differences in health in later life resulting from the racial convergence in school quality for cohorts born between 1910 and 1950 in southern states with segregated schools. Using data from the 1984-2007 National Health Interview Surveys linked to race-specific data on school quality, we find that reduct...

We present a new family of Nim games where the rules depend on a given ‘coloring’ of the tokens, each token being either black or white. The rules are as in Nim with the restriction that a white token on top of each heap is not allowed. We resolve the winning strategies of two disjoint game families played on two heaps. The heap-sizes with black tokens correspond to the numbers ⌊βn⌋, where β > ...

Plasma levels of lipids, lipoprotein-cholesterol and three major apolipoproteins (ApoA-I, A-II and C-II) were studied in 318 black and white males and females randomly sampled in Evans County, Georgia. Black-white differences in lipid and lipoprotein-cholesterol concentrations were observed, with low-density fractions higher in whites and high-density fractions higher in blacks. Plasma levels o...

Using aggregate data from the General Social Survey (GSS), 1974-1996, Lynn (1998) claims that the Black-White intelligence difference in the United States has not been narrowing over time. We replicate Lynn's analysis and challenge his conclusion by identifying several methodological problems. By analyzing changes in Black-White differences in the GSS vocabulary test across survey years, rather...
