Several studies from our laboratory show that axial stretch of the lower esophageal sphincter (LES) in an oral direction causes neurally mediated LES relaxation. Under physiological conditions, axial stretch of the LES is caused by longitudinal muscle contraction (LMC) of the esophagus. Because longitudinal muscle is composed of skeletal muscle in mice, vagal-induced LMC and LES relaxation are ...

We present a detailed map of the reddening in a 1.9◦ × 1.5◦ section of the Large Magellanic Cloud (LMC), constructed from UBV I photometry of 2069 O and B main sequence stars. We use two reddening-free photometric parameters to determine the line-of-sight reddening to these stars. We find a mean reddening, 〈E(B−V )〉LMC = 0.20 mag, with a non-Gaussian tail to high values. When the reddening is c...

Received ; accepted – 2 – ABSTRACT An expression is provided for the self-lensing optical depth of the thin LMC disk surrounded by a shroud of stars at larger scale heights. The formula is written in terms of the vertical velocity dispersion of the thin disk population. If tidal forcing causes ∼ 1 − 5% of the disk mass to have a height larger than 6 kpc and ∼ 10 − 15% to have a height above 3 k...

Abstract Since the hypervelocity stars were discovered in Milky Way, various mechanisms have been proposed to explain these runaway stars. Up now, however, dominant ejected mechanism of is still unclear. As largest and closest face-on satellite galaxy Large Magellanic Cloud (LMC) serves as a good target, allowing us study this issue. Based on high-precision astrometric parameters provided by Ga...

The Stone Representation Theorem for Boolean Algebras, first proved by M. H. Stone in 1936 ([4]), states that every Boolean algebra is isomorphic to a field of sets. This paper motivates and presents a proof.

We introduce Priestley rings of upsets (of a poset) and prove that inequivalent Priestley ring representations of a bounded distributive lattice L are in 1-1 correspondence with dense subspaces of the Priestley space of L. This generalizes a 1955 result of Bauer that inequivalent reduced field representations of a Boolean algebra B are in 1-1 correspondence with dense subspaces of the Stone spa...

In this paper we study the prime ideals space of a BL-algebra, proved that the prime ideals space being a 0 T-space and also a stone space. Furthermore, we study the properties of the prime ideals space.

We report the discovery of two new R Coronae Borealis (RCB) stars in the Large Magellanic Cloud (LMC) using the MACHO project photometry database. The identification of both stars has been confirmed spectroscopically. One is a cool RCB star (T ef f ∼ 5000 K) characterized by very strong Swan bands of C 2 and violet bands of CN, and weak or absent Balmer lines, G-band and 12 C 13 C bands. The se...
