We investigate the distance-redshift relation in a realistic inhomogeneous universe where the mass distribution is described by the mass function of Sheth and Tormen. It is found that the derived distance deviates systematically from the standard distance up to 10% depending on the choice of the lowest halo mass in which baryonic matter condensed to form luminous object such as galaxies. Remark...

We study the statistical properties of spacings between neighboring energy levels for multi-dimensional quantum harmonic oscillator that occur in a window [E, E + ΔE) fixed width ΔE as tends to infinity. This regime provides notable exception Berry–Tabor conjecture from chaos, and, reason, it was studied extensively by Berry and Tabor their seminal paper 1977. focus entirely on case (ratios of)...

Although myoneural mechanisms of arthropods have been extensively studied, comparatively little work has so far been carried out on the central connexions of motor units. The effect of motor discharges has usually been investigated with nerves isolated from their ganglia, and hence the role of the efferent synapses in modifying the information transmitted to the muscle is relatively unknown. On...
