We examine surface modes at the nematic-isotropic interface in polymer-liquid-crystal mixtures using the dynamical Landau-de Gennes model for the orientational (non-conserved) order parameter coupled with Cahn-Hilliard equation for concentration (conserved order parameter) and with hydrodynamic degrees of freedom. The generalized dispersion relation is obtained and analyzed in particular cases....

We develop a methodology to analyze capital misallocation (dispersion in static marginal products) measure the contributions of technological/informational frictions and a rich class of firm-specific factors. An application to Chinese manufacturing firms reveals that adjustment costs and uncertainty, while significant, generate only a modest amount of MPK dispersion, which stems largely from ot...

We describe a new scanning microscopy technique, phase-dispersion microscopy (PDM). The technique is based on measuring the phase difference between the fundamental and the second-harmonic light in a novel interferometer. PDM is highly sensitive to subtle refractive-index differences that are due to dispersion (differential optical path sensitivity, 5 nm). We apply PDM to measure minute amounts...

In classical analysis of variance, dispersion is measured by considering squared distances of sample elements from the sample mean. We consider a measure of dispersion for univariate or multivariate response based on all pairwise distances between-sample elements, and derive an analogous distance components (DISCO) decomposition for powers of distance in (0,2]. The ANOVA F statistic is obtained...

The procedure for determining the six-dimensional phase space volume of high energy beams in the SLAC Linear Collider (SLC) requires multiple transverse profile and lattice measurements. The standard use of these measurements to determine the emittance and betatron functions is reviewed, and complications from anomalous dispersion are included. Anomalous dispersion influences betatron matching ...

We present a quantitative measure of the internal color dispersion within galaxies, which quantifies differences in galaxy morphology as a function of observed wavelength. We apply this statistic to a sample of local galaxies with archival images at 1500 Å and 2500 Å from the Ultraviolet Imaging Telescope, and ground–based B–band observations in order to investigate how the internal dispersion ...

In the limit of small concentrations and weak applied electric fields, the dielectric permittivity of suspensions of arbitrarily shaped, shelled and charged particles is calculated. It is proved that the dielectric behavior at low frequencies is dominated by the effects of the diffusion of the free charges on the shell surfaces. Our theoretical formula is valid in the low range of frequencies (...

We have conducted a search of 19 southern Galactic globular clusters for sub-millisecond pulsars at 660 MHz with the Parkes 64-m radio telescope. To minimize dispersion smearing we used the CPSR baseband recorder, which samples the 20 MHz observing band at the Nyquist rate. By possessing a complete description of the signal we could synthesize an optimal filterbank in software, and in the case ...

We axiomatize, in an Anscombe-Aumann framework, the class of preferences that admit a representation of the form V (f) = (d), where is the mean utility of the act f with respect to a given probability, d is the vector of state-by-state utility deviations from the mean, and (d) is a measure of (aversion to) dispersion that corresponds to an uncertainty premium. The key feature of these mean-disp...

We demonstrate two techniques to reduce the effects of fiber chromatic dispersion in fiber-wireless systems incorporating external modulators. We theoretically and experimentally show that the achievable link distance can be increased by varying the chirp parameter of the modulator to give large negative chirp using a dual-electrode Mach–Zehnder modulator (MZM) biased at quadrature. In addition...
