Increased encephalization, or larger brain volume relative to body mass, is a repeated theme in vertebrate evolution. Here we present an extensive sampling of relative brain sizes in fossil and extant taxa in the mammalian order Carnivora (cats, dogs, bears, weasels, and their relatives). By using Akaike Information Criterion model selection and endocranial volume and body mass data for 289 spe...

We investigated the structure, organization, and developmental regulation of soybean Kunitz trypsin inhibitor genes. The Kunitz trypsin inhibitor gene family contains at least 10 members, many of which are closely linked in tandem pairs. Three Kunitz trypsin inhibitor genes, designated as KTi1, KTi2, and KTi3, do not contain intervening sequences, and are expressed during embryogenesis and in t...

BACKGROUND In Kazakhstan, as in many other countries, a transformation of the traditional stereotypes of reproductive behavior, and change the types of family relationships is occurred. It is caused by social status changes, by the transformation of women's valuable orientations and social-role attitudes. The objective of this study was to identify the indicators of reproductive units and the m...

Transformation of a response variable can greatly expand the class problems for which linear regression model or mixed-model is appropriate. Beginning with fundamental work Box and Cox, maximum-likelihood-like estimation has been applied to select transformation from among family transformations, possible goals achieving approximate normality, removing nonlinearity in mean function, stabilizing...

The singular value decomposition (SVD) technique is extended to incorporate the additive components for approximation of a rectangular matrix by the outer products of vectors. While dual vectors of the regular SVD can be expressed one via linear transformation of the other, the modified SVD corresponds to the general linear transformation with the additive part. The method obtained can be relat...

We show that for a certain family of integrable reversible transformations, the curves of periodic points of a general transformation cross the level curves of its integrals. This leads to the divergence of the normal form for a general reversible transformation with integrals. We also study the integrable holomorphic reversible transformations coming from real analytic surfaces in C with non-d...

Outlier detection based on the Mahalanobis distance (MD) requires an appropriate transformation in case of compositional data. For the family of logratio transformations (additive, centered and isometric logratio transformation) it is shown that the MDs based on classical estimates are invariant to these transformations, and that the MDs based on affine equivariant estimators of location and co...

(Fam Med 2010;42(7):469-70.) We in academic family medicine have a tremendous amount of work ahead of us during this period of major transformation of the health care system in general and primary care practice in particular. There are both great opportunities and daunting tasks embedded in this transformation, and I plan to use the President’s Column pretty actively over the next year to give ...
