let $g=(v,e)$ be a connected graph. the eccentric connectivity index of $g$, $xi^{c}(g)$, is defined as $xi^{c}(g)=sum_{vin v(g)}deg(v)ec(v)$, where $deg(v)$ is the degree of a vertex $v$ and $ec(v)$ is its eccentricity. the eccentric distance sum of $g$ is defined as $xi^{d}(g)=sum_{vin v(g)}ec(v)d(v)$, where $d(v)=sum_{uin v(g)}d_{g}(u,v)$ and $d_{g}(u,v)$ is the distance between $u$ and $v$ ...

reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methyl-imi...

Coagulation factor XI was purified from human plasma using ion-exchange chromatography and affinity chromatography on high molecular weight kininogen-Sepharose. A monospecific precipitating antiserum was prepared and used to study factor XI antigen. Factor XI did not migrate during electrophoresis at pH 8.3. High molecular weight kininogen (HMWK), an alpha globulin, reversibly associates with f...

Collagen type XI is a component of hyaline cartilage consisting of alpha 1(XI), alpha 2(XI), and alpha 3(XI) chains; with 5-10% of the total collagen content, it is a minor but significant component next to type II collagen, but its function and precise localization in cartilaginous tissues is still unclear. Owing to the homology of the alpha 3(XI) and alpha 1(II) collagen chains, attempts to p...

Washed platelets, contaminated with less than 0.20% plasma factor XI, were examined for the presence of factor XI antigen and activity. These platelets contained a factor-XI-like coagulant activity (0.67 +/- 0.11 U/10(11) platelets) that remained constant after successive washes. By means of indirect immunofluorescence, a monospecific antibody to factor XI showed specific staining of both norma...

Abstract We consider d-order Markov chains satisfying a conditional constraint E(aθ(Xi−1, Xi) | Xi−1) = 0, where Xi−1 = (Xi−1, . . . , Xi−d). These comprise quasi-likelihood models and nonlinear and conditionally heteroscedastic autoregressive models with martingale innovations. Estimators for θ can be obtained from estimating equations ∑n i=1Wθ(Xi−1) aθ(Xi−1, Xi) = 0. We review different crite...

Max-3-SAT. In this problem, the domain is {0, 1}; a collection of constraint types are disjunctions of the form {xi∨xj ∨xk, xi∨xj ∨xk, xi∨xj ∨xk, . . . , xi∨xj ∨xk, xi∨xj, . . . , xi∨ xj, xi, xi} resulting in total of 14 constraint types. Max-Cut. Here, the domain is again {0, 1}, the collection of constraint types is simply {vi 6= vj}. Intuitively, we have one such constraint for each edge in ...

In contrast to the general trend for glaciers of the Southern Patagonia Icefield, Glaciar Pio XI has experienced a large cumulative frontal advance since 1945. In an effort to better understand this advancing behaviour, this paper presents a synoptic analysis of frontal fluctuations (1998–2014), ice velocities (1986–2014), ice-surface elevations (1975–2007) and supraglacial moraines (1945–2014)...

Utterances of counterfactual conditionals are typically attended by the information that their antecedents are false. But there is as yet no account of the source of this information that is both detailed and complete. This paper describes the problem of counterfactual antecedent falsity and argues that the problem can be addressed by appeal to an adequate account of the presuppositions of vari...

The traditional engineering approach to error estimation assumes that we know the probabilities of different values of measurement error ∆xi def = e xi − xi. Yet in many practical situations, we only know the upper bound ∆i for this error. Hence after the measurement, the only information that we have about xi is that it belongs to the interval xi def = [e xi−∆i, e xi+∆i]. In this case, we have...
