Load theory of attention proposes that distractor processing is reduced in tasks with high perceptual load that exhaust attentional capacity within task-relevant processing. In contrast, tasks of low perceptual load leave spare capacity that spills over, resulting in the perception of task-irrelevant, potentially distracting stimuli. Tsal and Benoni (2010) find that distractor response competit...

The variational treatment of spin waves in the randomly diluted Heisenberg ferromagnet at zero temperature is studied. It is argued that a convenient variational principle for the excitation spectrum of an alloy is difficult to formulate rigorously. However, at extremely long wavelengths a simple variational calculatation probably has approximate validity providing localized excitations in isol...

Abstract In this article, detailed physicochemical characterization of ethylene glycol and caffeine + mixtures is performed based on density, viscosity refractive indices measurements in temperature range from (288.15 to 343.15) K. The apparent molar volume (V?), at infinite dilution (V?o), Masson's experimental slope (Sv), limiting expansibility, (E?o), B-coefficient, thermodynamical parameter...

The analysis of total intensity light scattering from solutions of macromolecules is discussed, covering the concentration range from infinite dilution to concentrated solutions, with a few examples for the scattering from colloidal dispersions of particles and micelles. The dependence on scattering angle is included over this entire range. Most of the discussion is limited to the Rayleigh-Gans...

The idea that the universe has zero total energy when one includes the contribution from the gravitational field is reconsidered. A Hamiltonian is proposed as an energy for the exact equations of FRW cosmology: it is then shown that this energy is constant. Thus open and critically open FRW universes have the energy of their asymptotic state of infinite dilution, which is Minkowski space with z...

We describe the design and testing of a new all-metal differential ebulliometer which is capable of working in the range 230 to 400 K at pressures to 3 MPa. It can be used to measure pure fluid vapor pressures and P ,T,x,y and infinite dilution activity coefficient data for binary mixtures. Tests for superheating and adjustments for condensed vapor holdup are described. Results are shown for pu...

a group g is said to be a (pf)c-group or to have polycyclic-by-finite conjugacy classes, if g/c_{g}(x^{g}) is a polycyclic-by-finite group for all xin g. this is a generalization of the familiar property of being an fc-group. de falco et al. (respectively, de giovanni and trombetti) studied groups whose proper subgroups of infinite rank have finite (respectively, polycyclic) conjugacy classes. ...
