The aim of this study was to assess high-resolution computed tomography (HRCT) findings of exogenous lipoid pneumonia. High-resolution computed tomography was obtained in 25 patients with proven exogenous lipoid pneumonia resulting from aspiration of squalene (derived from shark liver oil). Diagnosis was based on biopsy (n = 9), bronchoalveolar lavage (n =(More)
We investigated the activation of sensory and motor areas involved in the production of typing movements using functional magnetic resonance imaging (fMRI). Eleven experienced typists performed tasks, in which the spatial and temporal requirements as well as the number of digits involved were varied. These included a simple uni-digit repetitive task, a(More)
Interactions between microtubules and filamentous actin (F-actin) are essential to many cellular processes, but their mechanisms are poorly understood. We investigated possible roles of the myosin family of proteins in the interactions between filamentous actin (F-actin) and microtubules of budding yeast Saccharomyces cerevisiae with the general myosin(More)
Digital color halftoning is the process of transforming continuous-tone color images into images with a limited number of colors. The importance of this process arises from the fact that many color imaging systems use output devices such as color printers and low-bit depth displays that are bilevel or multilevel with a few levels. The goal is to create the(More)
The mitochondrial elongation factor EF-Tu (tufM) in rice (Oryza sativa L.) was isolated and characterized. The rice tufM cDNA clone contained 1,726 nucleotides and coded for a 453 amino acid protein including a putative mitochondrial transit peptide of 64 amino acid residues. This coding region was composed of 12 exons and 11 introns. The deduced amino acid(More)
We present an autoregressive model-based method which enables accurate respiratory rate extraction from pulse oximeter recordings over a wide range: 12–48 breaths/min. The method uses the optimal parameter search (OPS) technique to estimate accurate AR parameters which are then factorized into multiple pole terms. The pole with the highest magnitude is(More)
The quality of products from a machine tool system is largely determined by the tolerances maintained, which is a function of how well the desired contour is tracked. To mitigate contour errors in a three axis machine tool feed drive system, the control development in this paper is based on an error system that is transformed into tangential, normal and(More)
—This paper investigates the spatial correlation characteristics of multiple antenna arrays deployed in wireless communication systems. First, we derive a general closed-form formula for the spatial correlation function (SCF) of a multiple antenna array with arbitrary array configuration under uniform signal angular energy distribution. Based on this(More)
The successful use of the Design of Experiments (DOE) and Response Surface Modeling (RSM) approaches in an optimization study for a multilayer interdigitated passband filter is presented. The medium of interest is Liquid Crystal Polymer (LCP) and the frequency band is in the 60 GHz range. The two figures of merit chosen are the resonating frequency f o and(More)
