To optimize the subindex for functional longevity in Austrian Fleckvieh, an approximate multivariate approach was analyzed. Genetic parameters for functional longevity and five type traits were estimated multivariately based on yield deviations. Genetic parameters differed slightly from the ones used in the routine evaluation. Indices and reliabilities computed in a full multivariate approach w...

We show how to construct power indices that respect proportionality between power and weight from average representations of a game. If restricted to account for the lack of power of dummy voters, average representations become coherent measures of voting power, such that the resulting power distributions are proportional to the distribution of weights. Imposing other restrictions may lead to a...

Mild-to-moderate vitamin C depletion in weanling guinea-pigs affects pyridinoline:deoxypyridinoline (collagen cross-link) ratios in femur shaft and urine, attributed to impairment of hydroxylation of collagen lysine. We investigated: (1). whether the picture at two time points is compatible with progressive accumulation of abnormal collagen; (2). whether any changes are seen in skin, where litt...

Abstract Large-scale interdependent teleconnections influence precipitation at various spatio-temporal scales. Selecting the relevant climate indices based on geographical location is important. Therefore, this study focuses spatial multivariate selection of influencing variability over India, using partial least square regression and variable importance projection technique. 17 gridded dataset...

Background Traditionally, embryo incubation and assessment daily has been under a light microscope, these observations are inevitably restricted to specific times and considering that the development of the embryo is a dynamic process, several critical stages in between observations may go unnoticed. For this reason, the new technologies, time lapse monitoring, have focused on the research for ...

Selection criteria that can facilitate grain yield improvement would be considered important plant breeding tools. We assessed the value of spectral refl ectance indices (SRI) as indirect selection tools for grain yield improvement in winter wheat (Triticum aestivum L.). The objectives of this study were to estimate genetic correlation between SRI and grain yield, heritability, response to sele...

Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...

Feature selection for unsupervised data is a difficult task because a reference partition is not available to evaluate the relevance of the features. Recently, different proposals of methods for consensus clustering have used external validity indices to assess the agreement among partitions obtained by clustering algorithms with different parameter values. Theses indices are independent of the...

Serial assessments of neurocognitive functioning in athletes with concussion are commonly used for return to play decisions. This study provides reliable change indices (RCIs) for computerized tests from 40 NCAA Division I collegiate athletes that suffered a sports-related concussion. The normative data that resulted from the RCIs and subsequent analyses of differences between improved and not ...
