Recently, we initiated in [Systems Control Lett., 26 (1995), pp. 245–251] the study of exponential stability of neutral stochastic functional differential equations, and in this paper, we shall further our study in this area. We should emphasize that the main technique employed in this paper is the well-known Razumikhin argument and is completely different from those used in our previous paper ...

We transfer an optical frequency over 251 km of optical fiber with a residual instability of 6x10(-19) at 100 s. This instability and the associated timing jitter are limited fundamentally by the noise on the optical fiber and the link length. We give a simple expression for calculating the achievable instability and jitter over a fiber link. Transfer of optical stability over this long distanc...

This course prepares students to apply computational approaches to data analysis and visualization to real information from a variety of disciplines and applications. Data visualization is the interactive visual exploration of information using 2-D and 3-D graphics using techniques that highlight patterns and relationships. Data analysis incorporates data management, data transformations, stati...

An accumulation of knowledge with respect to biodiversity on the earth has continued for many years because of its great importance and the interest in investigating it. But further studies are necessary for bacterial biodiversity to reach the stage of complete elucidation. Moreover there is a trial calculation that only 1% of bacteria that actually exist on earth have been isolated (Rondon et ...

BACKGROUND Interleukin (IL)-8 plays important roles in the recruitment and activation of immune cells during visceral leishmaniasis (VL). Genetic variations in IL-8 modulate the expression of IL-8 protein and may be associated with VL. This study aimed to evaluate polymorphisms at the IL-8 -251 position in VL patients. METHODS This cross-sectional study was performed on three groups: Leishman...

Two myosin heavy chain cDNA clones (251 and 110), constructed from chick embryonic skeletal muscle mRNA, were subjected to extensive DNA sequence analysis. A complete description of the DNA sequence of clone 251 was obtained. This 1.5-kilobase pair cDNA sequence specified the COOH-terminal 439 amino acids of the myosin heavy chain, and included the entire 3' nontranslated region. The translated...

Methods From January 2008 to December 2011, 251 (mean age: 34+/-6) pregnant women with a T-ACE positive screen for risk of alcohol consumption while pregnant were evaluated in our regional alcohol center. The T-ACE asks four questions that give the assessment its name: Tolerance (how many drinks does it take to make you feel high?), Annoyed (have people ever annoyed you by criticizing your drin...

HST images (with WFPC2) of PHL 909 (z = 0.171) and PG 0052+251 (z = 0.155) show that these luminous radio-quiet quasars each occur in an apparently normal host galaxy. The host galaxy of PHL 909 is an elliptical galaxy (∼ E4) and the host of PG 0052+251 is a spiral (∼ Sb). Both host galaxies are several tenths of a magnitude brighter than L, the characteristic Schechter luminosity of field gala...
