BACKGROUND There is increasing interest in the predictive value of C-reactive protein (CRP) and fibrin D-dimer in the prediction of ischemic heart disease (IHD). We assessed their joint and independent associations with IHD in a large combined analysis of 2 population cohorts. METHODS AND RESULTS Men aged 49 to 66 years from the general populations of Caerphilly and Speedwell were studied bet...
Beefmaster, Brahman, Brangus, and Santa Gertrudis field data records were used to determine genetic and environmental parameter estimates using a multiple-trait, pseudo-expectation approach. Adjusted birth weight, 205-d weight, and postweaning gain records were analyzed for each breed. Also, Brangus weaning sheath and navel scores were both analyzed using a single-trait, pseudo-expectation meth...
Based on the results of Blum, Shub and Smale 1], Meer 5], Cucker and Matamala 3] and Koiran 7], we develop the study of real computation models restricted to additive operations. More speciically we introduce some complexity classes deened by algebraic circuits and we study their relationships with the real computation model. We show that the languages accepted by nonuniform additive circuits o...
Crossbreeding parameters for milk production and reproductive traits and for cow live weight (LW) of crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) cattle were estimated using data from a dairy herd in the lowland coastal tropics of Kenya. An individual animal model was fitted to the data to estimate the breed cross means of 25 genotypes. The means were then regressed on...
Let R be a ring and U be a Lie ideal of R. Suppose that σ, τ are endomorphisms of R. A family D = {d n } n ∈ N of additive mappings d n :R → R is said to be a (σ,τ)- higher derivation of U into R if d 0 = I R , the identity map on R and [Formula: see text] holds for all a, b ∈ U and for each n ∈ N. A family F = {f n } n ∈ N of additive mappings f n :R → R is said to be a generalized (σ,τ)- high...
We combine high-level theoretical and ab initio understanding of graphite to develop a simple, parametrized force-field model of interlayer binding in graphite, including the difficult non-pairwise-additive coupled-fluctuation dispersion interactions. The model is given as a simple additive correction to standard density functional theory (DFT) calculations, of form ΔU(D) = f(D)[U(vdW)(D) - U(D...
Let R be an associative ring not necessarily with identity element. For any x, y ∈ R. Recall that R is prime if xRy = 0 implies x = 0 or y = 0, and is semiprime if xRx = 0 implies x = 0. Given an integer n ≥ 2, R is said to be n−torsion free if for x ∈ R, nx = 0 implies x = 0.An additive mapping d : R → R is called a derivation if d(xy) = d(x)y + yd(x) holds for all x, y ∈ R, and it is called a...
Let Xt be any additive process in R d. There are finite indices δi, βi, i = 1, 2 and a function u, all of which are defined in terms of the characteristics of Xt, such that lim inf t→0 u(t) −1/η X * t = 0, if η > δ1, ∞, if η < δ2, lim sup t→0 u(t) −1/η X * t = 0, if η > β2, ∞, if η < β1, a.s., where X * t = sup 0≤s≤t |Xs|. When Xt is a Lévy process with X0 = 0, δ1 = δ2, β1 = β2 and u(t) = t. Th...
Whole genome duplication (WGD) is an evolutionary phenomenon, which causes significant changes to genomic structure and trait architecture. In recent years, a number of studies decomposed the additive genetic variance explained by different sets of variants. However, they investigated diploid populations only and none of the studies examined any polyploid organism. In this research, we extended...
