PURPOSE To compare the changes in visually guided performance as a function of age between Royal College of Surgeons (RCS) dystrophic and congenic rats and to correlate photoreceptor cell number with visually guided performance in age-matched populations of RCS dystrophic rats. METHODS The visually guided performances of RCS dystrophic (n=6) and congenic (n=7) rats were studied from 0.75 to 1...

BACKGROUND Refractory coeliac sprue (RCS) with an immunophenotypically aberrant clonal intraepithelial lymphocyte (IEL) population is considered a cryptic form of intestinal T cell lymphoma. AIMS To investigate the distribution of the abnormal and monoclonal IEL population in the digestive tract of RCS patients. PATIENTS AND METHODS We compared the frequency of lymphocytic gastritis (LG) an...

OBJECTIVE To determine the relation of maxillary sinus retention cysts (RCs) to ostiomeatal complex (OMC) obstruction and anatomic variation of the paranasal sinuses. METHODS The results of 410 computed tomographic scans of the sinuses ordered by otolaryngologists in an academic center during a 1-year period were reviewed. Computed tomographic scans with maxillary sinus RCs were studied to de...

Carbohydrate-containing macromolecules on pigment epithelium (PE) and photoreceptor outer segment (OS) membranes of 14 to 16-day-old Royal College of Surgeons (RCS) rats and their genetic control (RCS-rdy+) have been localized with peroxidase-conjugated lectins from wheat germ agglutinin (WGA), Ricinus communis (RCA), Lens culinaris (LCA), and concanavalin A (Con A). All lectins stain the plasm...

The scattering characteristics of a phased array depends on its feed network. The variation of scattered fields within the feed network affects the antenna mode scattering. In this paper, an attempt is made to determine the radar cross section (RCS) of a planar array with parallel-feed network. The scattered field of the array is obtained by following the path of the signals through the antenna...

This paper presents a method for measuring signal backscattering from an RFID tag and calculating tag radar cross-section (RCS), which depends on the chip input impedance. We present a derivation of a theoretical formula for RFID tag radar cross-section and an experimental RCS measurement method using a network analyzer connected to an antenna in an anechoic chamber where the tag is also locate...

* This paper is a condensation of 4-D/RCS: A Reference Model Architecture for Demo III, NISTIR 5994, March 1997 ABSTRACT 4-D/RCS is a reference model architecture that integrates the NIST (National Institute of Standards and Technology) RCS Real-time Control System [Albus & Meystel],with the German (Universitat der Bundeswehr Munchen) VaMoRs 4D approach to dynamic machine vision [Dickmanns]. 4-...

BACKGROUND Rural medical workforce shortage contributes to health disadvantage experienced by rural communities worldwide. This study aimed to determine the regional results of an Australian Government sponsored national program to enhance the Australian rural medical workforce by recruiting rural background students and establishing rural clinical schools (RCS). In particular, we wished to det...

Currently there is no control for real-time traffic sources in IP networks. This is a serious problem because real-time traffic can not only congest the network but can also cause unfairness and starvation of TCP traffic. In this paper, a new rate control scheme, RCS, is introduced for real-time traffic in networks with high bandwidth-delay products and high bit error rates. RCS is based on the...

Spaceborne synthetic aperture radars (SARs) measure surface radar cross section (RCS) with ground resolutions from 25 to 100 m. In turn, the RCS of the ocean surface is a function of wind speed and direction. Over the past few years, we have been routinely using RCS measured by the RADARSAT SAR to compute highresolution wind speed. We have converted over 3000 wide-swath SAR RCS images, provided...
