We consider uid models with innnite buuer size. Let fZ N (t)g be the net input rate to the buuer where fZ N (t)g is a superposition of N homogeneous alternating on-oo ows. Under heavy traac environment fZ N (t)g converges in distribution to a centered Gaussian process with covariance function of a single ow. The aim of this paper is to prove the convergence of the stationary buuer content proce...

We identified a seven-pass transmembrane receptor of the cadherin superfamily, designated Flamingo (Fmi), localized at cell-cell boundaries in the Drosophila wing. In the absence of Fmi, planar polarity was distorted. Before morphological polarization of wing cells along the proximal-distal (P-D) axis, Fmi was redistributed predominantly to proximal and distal cell edges. This biased localizati...

This paper addresses model-based analysis of string instrument sounds. In particular, it reviews the application of autoregressive (AR) modeling to sound analysis/synthesis purposes. Moreover, a frequency-zooming autoregressive moving average (FZ-ARMA) modeling scheme is described. The performance of the FZ-ARMA method on modeling the modal behavior of isolated groups of resonance frequencies i...

Functional tissues not only polarize their epithelia in the apical-basolateral axis, but also often display a polarity within the plane of the epithelium. In Drosophila, all adult structures are derived from epithelia called imaginal discs and display planar polarization; the eye and the wing are particularly well suited for analysis. Studies of their polarization have identified several conser...

Solvent sublation has been studied for the separation and determination of trace iron(II) in various kinds of water samples. A strongly magenta-colored anionic [Fe(FZ)3](4-) complex was formed at pH 5.0 upon adding 3-(2-pyridyl)-5,6-bis(4-phenylsulfonic acid)-1,2,4-triazine (ferrozine, FZ) to the sample solution. Tetrabutylammonium bromide (TBAB) was added in the solution to form the (TBA)4[Fe(...

Members of the low density lipoprotein receptor family (LDLR), LRP5/6, were shown to interact with the Frizzled (Fz) receptors and to function as Wnt coreceptors. Here we show that mLRP4T100, a minireceptor of LRP1, another member of the LDLR family, interacts with the human Fz-1 (HFz1), previously shown to serve as a receptor transmitting the canonical Wnt-3a-induced signaling cascade. However...

In this issue of Cell, Inoue et al. (2004) reports that LIN-18, an atypical receptor tyrosine kinase related to mammalian Ryk and Drosophila Derailed, mediates Wnt signaling in parallel to LIN-17/Frizzled (Fz) during worm vulval development. LIN-18/Ryk and LIN-17/Fz appear to exhibit distinct Wnt specificity, and surprisingly, the LIN-18 intracellular domain may be dispensable.

Studies on neural decision making mostly investigated fast corrective adjustments of arm movements. However, fast leg movement corrections deserve attention as well, since they are often required to avoid falling after balance perturbations. The present study aimed at elucidating the mechanisms behind fast corrections of tripping responses by analyzing the concomitant leg muscle activity change...

STUDY OBJECTIVE This study was designed to assess the efficacy of using Fz as an additional electrode in screening arousals during polysomnography in children. METHODS Polysomnograms from 24 children were randomly selected from a sleep-study database of children from different diagnostic categories. Of the children whose polysomnograms selected, 5 were normal, 5 had severe obstructive sleep a...
