A Similarity Matrix for Preserving Haplotype Diversity Amongst Parents in Genomic Selection
Journal of Animal Breeding and Genetics, Volume 142, Issue 6, Page 652-668, November 2025.ABSTRACT In genomic selection, balancing genetic gain with the preservation of genetic diversity is a critical challenge, requiring innovative approaches to parent selection. Traditional methods risk losing valuable genetic diversity by not fully accounting for the complex patterns of haplotype distribution.

Natural Resource Modeling, Volume 38, Issue 4, November 2025.ABSTRACT This study explores existence of hydra effect and sustainable harvesting strategies in three species food chain system with all‐purpose Holling type response functions (HT‐I, II, III, and IV). The hydra effect (as mentioned in Sieber and Hilker 2012) is superficially ecological paradox which refers to an increase of a species population size ...

Journal of Numerical Analysis and Approximation Theory, 2010 In this paper, we obtain new results concerning the generalizations of additive and multiplicative majorizations by means of exponential convexity. We prove positive semi-definiteness of matrices generated by differences deduced from majorization type ...

Mokslas: Lietuvos Ateitis, 2015 Semidefinite Programming (SDP) is a fairly recent way of solving optimization problems which are becoming more and more important in our fast moving world. It is a minimization of linear function over the intersection of the cone of positive semidefinite

Scanner Data and the Construction of Inter‐Regional Price Indexes
Review of Income and Wealth, Volume 71, Issue 4, November 2025.ABSTRACT The paper uses scanner data to measure the welfare effects of differing product availability across six Japanese regions. To eliminate the chain drift problem associated with the use of scanner data, various multilateral indexes were computed: GEKS, Geary–Khamis, and Weighted Time Product Dummy Hedonic price indexes.

Sensitivity of Perron and Fiedler Eigenpairs to Structural Perturbations of a Network
Numerical Linear Algebra with Applications, Volume 32, Issue 5, October 2025.ABSTRACT One can estimate the change of the Perron and Fiedler values for a connected network when the weight of an edge is perturbed by analyzing relevant entries of the Perron and Fiedler vectors. This is helpful for identifying edges whose weight perturbation causes the largest change in the Perron and Fiedler values.
