A 65 year gentleman had complaints of difficulty in swallowing primarily for solids along with foreign body sensation in throat for six months duration. Patient also had to do multiple attempts at swallowing the bolus. Occasionally patient also had episodes of coughing during swallowing of liquids. Patient had no loss of weight, fever and hematemesis. Barium swallow revealed narrowing at level ...

Received ; accepted – 2 – ABSTRACT We performed SPH simulations to study the nuclear morphology of a barred galaxy NGC 4314. We have constructed the mass models based on the results of a profile decomposition into disk, bulge, and bar components. Our models have three different nuclear structures according to the assumption about the nuclear bar: no nuclear bar, a synchronous nuclear bar and a ...

Females homozygous for the sex-linked dominant, Bar, occasionally give rise to wild-type reversions and to forms with more extreme eye reduction than Bar. This behavior was shown by Sturtevant' to result from unequal crossing-over. The Bar-reverted type was considered to be a deficiency for the Bar gene; while the extreme form, called Ultra-Bar or Double-Bar, was interpreted as a duplication fo...

Bar charts are common data representations in scientific and technical papers. In order to recognize the printed bar charst, we present a new Hough based bar chart recognition algorithm which combines syntactic analysis into segmentation. We first detect the most salient feature in any bar chart, bar patterns, using syntactic analysis in the Hough domain. Then we group text primitives according...

This paper describes a general methodology for simplifying the design and analysis of BAR protocols. BAR protocols allow the participation of Byzantine, Altruistic, and Rational players. Because BAR protocols tolerate both arbitrary behaviors by some nodes and selfish behavior by the rest, they are appropriate for service and applications spanning multiple administrative domains. We focus our a...

We have used 2D Fabry-Perot absorption-line spectroscopy of the SB0 galaxy NGC 7079 to measure its bar pattern speed, Ωp. As in all previous cases of bar pattern speed measurements, we find a fast bar. We estimate that NGC 7079 has been undisturbed for at least the past Gyr or roughly 8 bar rotations, long enough for the bar to have slowed down significantly through dynamical friction if the di...

Evidence of a misaligned secondary bar, within the primary bar of the Large Magellanic Cloud (LMC), is presented. The density distribution and the dereddened mean magnitudes ( ) of the red clump stars in the bar I0 obtained from the Optical Gravitational Lensing Experiment II data are used for this study. The bar region that predominantly showed a wavy pattern in the line of sight in a recent p...
