For various lattice gas models with nearest neighbour exclusion (and, in one case, second-nearest neighbour exclusion as well), we obtain lower bounds on m, the average number of particles on the non-excluded lattice sites closest ∗We dedicate this work to the memory of Ann Stell, beloved friend of OP and beloved wife of GS.

This paper is about Arthur Prior’s first published piece of philosophy, “The Nation and the Individual” (1937). Its aims are (1) to show that Prior made a remarkable contribution to social ontology in the 1930s; (2) to interpret Prior’s proposal as a promise of reduction by translation; (3) to connect Prior’s ideas with Searle’s social ontology. I. Arthur Prior was 23 when he published his firs...

PURPOSE Visual prostheses offer a possibility of restoring useful reading ability to the blind. The psychophysics of simulating reading with a prosthesis using pixelized text has attracted attention recently. This study was an examination of the reading accuracy and efficiency of pixelized Chinese paragraphs after different parameters were altered. METHODS Forty native Chinese speakers with n...

Two hundred and forty mildly myopic schoolchildren aged 9-11 years were randomly allocated to three treatment groups and the progression of myopia was followed-up for three years. The treatment groups were: (1) minus lenses with full correction for continuous use (the reference group), (2) minus lenses with full correction to be used for distant vision only, and (3) bifocal lenses with +1.75 D ...

as a contemporary fiction writer, bizhan najdi is lessappreciated despite the fact that his short stories are of significant depthand deserve close examination. through the poetic language, “a plant inquarantine” creates a situation which provides a fertile ground to inspect therelation between past and present. a deep analysis of this relationship is themain focus of this paper. in this study,...

We show that public-key bit encryption schemes which support weak (i.e., compact) homomorphic evaluation of any sufficiently “sensitive” collection of functions cannot be proved message indistinguishable beyond AM ∩ coAM via general (adaptive) reductions, and beyond statistical zero-knowledge via reductions of constant query complexity. Examples of sensitive collections include parities, majori...

By considering the energy cost of messages carried by proteins as proportional to their information content we found experimental proof that proteins from all living organisms tend to have their estimated semantic content of information per unit mass, statistically, close to a constant. Thus, in the message carried by proteins −to achieve minimum energy waste− the rate of information content pe...

Children in single-parent families, particularly children born to unmarried parents, are at high risk for experiencing material hardship. Previous research based on cross-sectional data suggests that father involvement, especially visitation, diminishes hardship. This article uses longitudinal data to examine the associations between nonresident fathers' involvement with their children and mate...
