We show that an experimental demonstration of quantum contextuality using 2 degrees of freedom of single neutrons based on a violation of an inequality derived from the Peres-Mermin proof of the Kochen-Specker theorem would be more conclusive than those obtained from previous experiments involving pairs of ions [M. A. Rowe, Nature (London) 409, 791 (2001)10.1038/35057215] and single neutrons [Y...

In this paper, we extend the population genetics model of [5] to the case where a fraction of the population does not migrate after the selection process. Mathematically, we study the asymptotic behavior of solutions to the recursion un+1 = Qg[un] where Qg[u](x) = (1− g) ∫ R K(x− y)f(u(y))dy + gf(u(x)), 0 ≤ g ≤ 1 . In the above definition of Qg, K is a probability density function and f behaves...

A locally causal hidden-variable theory of quantum physics need not be constrained by the Bell inequalities if this theory also partially violates the measurement independence condition. However, such violation can appear unphysical, implying implausible conspiratorial correlations between the hidden variables of particles being measured and earlier determinants of instrumental settings. A nove...

We attempt to elucidate whether there might be a causal connection between the socioeconomic status (SES) of the rearing environment and obesity in the offspring using data from two large-scale adoption studies: (1) The Copenhagen Adoption Study of Obesity (CASO), and (2) The Survey of Holt Adoptees and Their Families (HOLT). In CASO, the SES of both biological and adoptive parents was known, b...

In 1952, Holt and Withers (1) described esterase-rich intracellular bodies in rat kidney and liver. In kidney, these bodies were spherical and were present chiefly in the proximal convoluted tubules. In liver, they appeared to be more irregular and were aligned along the bile canaliculi. The indoxyl method used for the demonstration of this enzyme by Holt (2) has recently been further improved ...
