Planar cell polarity (PCP) is a common feature in many epithelia, reflected in cellular organization within the plane of an epithelium. In the Drosophila eye, Frizzled (Fz)/PCP signaling induces cell-fate specification of the R3/R4 photoreceptors through regulation of Notch activation in R4. Except for Dl upregulation in R3, the mechanism of how Fz/PCP signaling regulates Notch in this context ...

THE ROLE OF FRIZZLED-1 AND FRIZZLED-3 IN OLFACTORY SENSORY NEURONAL TARGETING. Mina G. Safain. Department of Neurosurgery, Yale University School of Medicine, New Haven, CT. While most areas of the brain do not exhibit profound neurogenesis or continuing synaptogenesis in the adult, there are notable exceptions which include the olfactory and hippocampal regions of the nervous system. In the ol...

Wheat is among the world’s most important agricultural crops, with winter wheat accounting for approximately 25.5% of total crop in Lithuania. The unchangeable goal production to achieve good and economically beneficial yield, but such efforts are often based on conventional agrotechnological solutions, excessive fertilization, which uneconomical negatively affects soil, environment, human heal...

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...

Fractures of the zygomatic complex and their treatment have been the focus of much attention in the last 30 years. Treatment frequently depends on the surgical findings, experience, and discretion of the surgeon. Treatment of zygomatic complex (ZMC) fractures often requires stabilization at the frontozygomatic (FZ) suture. Frodel’ and Marentette’ have described the use of lag screw fixation of ...

Fig 2: A selected slice showing the SWI (A,B) and MIP (C, D) images with FH and FZ filters (α = 3, β = -0.1). Compared to FH (left), the FZ (right) showed clear improvement in the tissue contrast, both between gray and white matter tissue (B vs. A) and between veins and surrounding tissues (D vs. C). Fig 3: Determination of the optimal parameters α and β for FZ, using CoM. The optimal α is 2 t...

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...
