Before the first world war, local government boards advised district councils generally to employ health visitors: breastfeeding and child nutrition needed particular attention. In 1910, Hucknall District Council in Nottinghamshire, England, appointed nurse Ellen Woodcock to advise ...

Abstract Violation of the no-signaling principle may occur in PT-symmetric evolutions, that is, evolutions stem from Hamiltonians are symmetric with respect to parity and time-reversal, bipartite entangled states. The violation can be avoided by using a non-conventional inner product. We show even within formalism utilizes conventional product between physical state vectors separable Hilbert sp...

Context. The intergalactic medium (IGM) is believed to contain the majority of baryons in universe and trace same dark matter structure as galaxies, forming filaments sheets. Ly α absorbers, which sample neutral component IGM, have been extensively studied at low high redshift, but exact relation between absorption, large-scale observationally not well constrained. Aims. In this study, we aim c...
