e15658 Background: Leptomeningeal carcinomatosis occurs in approximately 5% of patients with cancer. The most common cancers involving the leptomeninges are breast and lung cancer. However, gastric adenocarcinoma has been rarely reported with leptomeningeal carcinomatosis (LMC). METHODS We analyzed 54 cases of cytological confirmed gastric LMC at 4 institutions from 1994 to 2007. RESULTS Ma...
A unital Fréchet algebra A is called contractible if there exists an element d ∈ A⊗̂A such that πA(d) = 1 and ad = da for all a ∈ A where πA : A⊗̂A → A is the canonical Fréchet A-bimodule morphism. We give a sufficient condition for an infinite-dimensional contractible Fréchet algebra A to be a direct sum of a finite-dimensional semisimple algebra M and a contractible Fréchet algebra N without an...
in this note the notion of interval-valued fuzzy b-algebras (briefly,i-v fuzzy b-algebras), the level and strong level b-subalgebra is introduced.then we state and prove some theorems which determine the relationshipbetween these notions and b-subalgebras. the images and inverse images ofi-v fuzzy b-subalgebras are defined, and how the homomorphic images andinverse images of i-v fuzzy b-subalge...
We describe a few recent microlensing results from the MA-CHO Collaboration. The aim of the MACHO Project was the identification and quantitative description of dark and luminous matter in the Milky Way using microlensing toward the Magellanic Clouds (LMC and SMC) and the Galactic bulge. We start with a discussion of the Hubble Space Telescope follow-up observations of the microlensing events t...
In this paper we introduce the notion of $varphi$-commutativity for a Banach algebra $A$, where $varphi$ is a continuous homomorphism on $A$ and study the concept of $varphi$-weak amenability for $varphi$-commutative Banach algebras. We give an example to show that the class of $varphi$-weakly amenable Banach algebras is larger than that of weakly amenable commutative Banach algebras. We charac...
I construct a near-IR star count map of the LMC and demonstrate, using the viewing angles derived in Paper I, that the LMC is intrinsically elongated. I argue that this is due to the tidal force from the Milky Way. The near-IR data from the 2MASS and DENIS surveys are ideally suited for studies of LMC structure, because of the large statistics and insensitivity to dust absorption. The survey da...
Leptomeningeal carcinomatosis (LMC), or neoplastic meningitis, occurs in about 5-20% of patients with metastatic cancer, depending on the type of the primary malignancy and kind of treatment received. The association of LMC with renal cell carcinoma (RCC) is a rare entity, and only two cases of papillary renal cell cancer with leptomeningeal metastasis have been reported. Leptomeningeal spread ...
We report on observations of the Large Magellanic Cloud with the Fermi Gamma-Ray Space Telescope. The LMC is clearly detected with the Large Area Telescope (LAT) and for the first time the emission is spatially well resolved in gamma-rays. Our observations reveal the massive star forming region 30 Doradus as a bright source of gamma-ray emission in the LMC. The observations furthermore show tha...
The oldest and most metal-poor Milky Way stars form a kinematically hot halo, which motivates the two major formation scenarios for our galaxy: extended hierarchical accretion and rapid collapse. RR Lyrae stars are excellent tracers of old and metal-poor populations. We measured the kinematics of 43 RR Lyrae stars in the inner regions of the nearby Large Magellanic Cloud (LMC) galaxy. The veloc...
چکیده: در این رساله ابتدا مفهوم c*-جبر را بیان می کنیم سپس با تجزیه وتحلیل دقیق مقاله های on frames in hilbert modules over pro-c*-algebras, projections on hilbert modules over locally c*-algebras. مفهوم c*-جبر موضعی و قاب ضربگرها در مدول های هیلبرت روی c*-جبرموضعی بیان می شود و نشان می دهیم برخی از ویژگیهای قابها در c*-مدول های هیلبرت برای قاب ضربگرها در مدول های هیلبرت روی c*-جبرموض...
