The authors obtain necessary and sufficient conditions for the existence of oscillatory solutions with a specified asymptotic behavior of solutions to a nonlinear neutral differential equation with distributed delay of third order. We give new theorems which ensure that every solution to be either oscillatory or converges to zero asymptotically. Examples dwelling upon the importance of applicab...

Abstract Three distinct paragenetic and compositional types of tourmaline were described from the Velence Granite surrounding contact slate. Rare, pitch-black, disseminated I (intragranitic tourmaline) occurs in granite, pegmatite, aplite; very rare, black to greenish-gray, euhedral II (miarolitic miarolitic cavities pegmatites; abundant, gray, brown yellow or even colorless, acicular III (meta...

The tight junction is an intricate seal between adjoining epithelial cells that also separates the apical and basolateral membranes within these cells. A paper in this issue of Cell by Umeda et al. (2006) demonstrates that loss of the ZO scaffolding proteins prevents the formation of tight junctions but surprisingly does not perturb apico-basal polarity.

This article examines New York City’s first attempt to regulate adult entertainment establishments through zoning provisions. Specifically, it discusses whether the adult-use zoning provisions comply with federal and state constitutional requirements, and it examines whether the adult-use amendments would cause a reduction in adult-use establishments in New York City, which would render the ame...

This paper investigates different strategies allowing integration of contextual information during the feature extraction stage of a cursive handwriting HMM-based recognition system. First we propose to use linear discriminant analysis (LDA) in order to integrate the class information during feature set building. Secondly several zoning strategies are used to integrate local contextual informat...

The stability of stratified Rivlin-Ericksen fluid in porous medium in the presence of suspended particles and magnetic field has been investigated. Upon application of normal mode technique, the dispersion relation was obtained. The important results obtained in this paper include the instability of non-oscillatory modes and the stability of oscillatory modes. Also, it was found that the system...

film coating solutions containing different grades of hpmc (e5, e15 and e50) with and without polyethylene glycol (with various molecular weights) were examined by an oscillatory method, using haake cv 100 rheometer. fundamental rheological parameters (?, g? and g² ) were measured over the frequency range from 0.04 to 2 hz. the variation with frequency of the loss tangent (a ratio of viscous to...
