Abstract Polarization indices such as the Foster-Wolfson index have been developed to measure extent of clustering in a few classes with wide gaps between them terms income distribution. However, Zhang and Kanbur (2001) failed empirically find clear differences polarization inequality measurement intertemporal distributional changes. This paper addresses this ‘distinction' problem on level resp...

In the probed-sinewave paradigm—used to study the dynamics of light adaptation—a small probe of light is superimposed on a sinusoidally flickering background. Detection threshold for the probe is measured at various times with respect to the flickering background. Here we present such stimuli using three methods: monoptic (the probe and the flickering background are presented to the same eye), ...

Abstract The noted Jewish scholar Harry Wolfson (d. 1929) claimed in youthful writings that the fifteenth‐century rabbinic thinker and physicist, Hasdai Crescas, was a pragmatist. This essay introduces evidence there are, indeed, significant analogies between elements of Crescas’s critique Aristotle Charles Peirce’s pragmatism. concludes primary work, Light Lord ( Or Hashem ), displays unique a...

Swelling media (e.g. gels, tumors) are usually described by mechanical constitutive laws (e.g. Hooke or Darcy laws). However, constitutive relations of real swelling media are not well-known. Here, we take an opposite route and consider a simple packing heuristics, i.e. the particles can’t overlap. We deduce a formula for the equilibrium density under a confining potential. We then consider its...

We consider the moduli space Rn of pairs of monic, degree n polynomials whose resultant equals 1. We relate the topology of these algebraic varieties to their geometry and arithmetic. In particular, we compute their étale cohomology, the associated eigenvalues of Frobenius, and the cardinality of their set of Fq-points. When q and n are coprime, we show that the étale cohomology of Rn/Fq is pur...
