Improving the stability of discretization zeros with the Taylor method using a generalization of the fractional-order hold

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2014
Remarkable improvements in the stability properties of discrete system zeros may be achieved by using a new design of the fractional-order hold (FROH) circuit. This paper first analyzes asymptotic behaviors of the limiting zeros, as the sampling period T

Bottlenecked but Booming: Strong Inbreeding in a Highly Invasive Freshwater Mussel

open access: yesMolecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT The ‘genetic paradox of invasions’ refers to successful invasive populations originating from low founder numbers. Theory predicts that such invaders should exhibit reduced genetic diversity and increased inbreeding, which should restrict their evolutionary potential and often lead to inbreeding depression.

Gratitude and well-being: a review and theoretical integration

open access: yes, 2010
This paper presents a new model of gratitude as a "life orientation towards noticing and appreciating the positive in life", incorporating not only the gratitude that arises following help from others, but also a habitual focusing on and appreciating the

Repeated genetic adaptation under demographic limits in kiwifruit

open access: yesThe Plant Journal, Volume 128, Issue 1, October 2026.
SUMMARY Population genetic theory predicts that species with narrow geographic distributions experience stronger genetic drift, higher inbreeding, and greater mutational burden than their widespread relatives, yet how demographic history shapes the genomic basis of adaptation remains poorly understood.

Livestock Multi‐Omics Integration: A Systematic Framework From Statistical Association to Causal Interpretation

open access: yesAdvanced Science, Volume 13, Issue 50, 7 September 2026.
A three‐tier livestock multi‐omics framework resolves four typical analytical pitfalls. Moving from statistical association through machine learning preprocessing to triple‐modal causal inference, it converts omics results into genomic selection and gene editing strategies to achieve One Health, underpinned by multi‐omics data, multimodal sequencing ...

Assessing different metrics of pedigree and genomic inbreeding and inbreeding effect on growth, fertility, and feed efficiency traits in a closed-herd Nellore cattle population

open access: yesBMC Genomics
Background The selection of individuals based on their predicted breeding values and mating of related individuals can increase the proportion of identical-by-descent alleles.

Genome-Wide Runs of Homozygosity Revealed Selection Signatures in Bos indicus

open access: yesFrontiers in Genetics, 2020
Genome-wide runs of homozygosity (ROH) are suitable for understanding population history, calculating genomic inbreeding, deciphering genetic architecture of complex traits and diseases as well as identifying genes linked with agro-economic traits ...

Seascape Genomics Uncovers Weak Signs of Local Adaptation Despite Bottleneck Events, High Inbreeding and Low Heterozygosity in the Vulnerable Smooth Hammerhead Shark (Sphyrna zygaena)

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The smooth hammerhead shark (Sphyrna zygaena) is a highly migratory pelagic predator classified as Vulnerable due to overexploitation and rapid climate change. However, its genomic diversity, connectivity patterns and demographic history remain poorly understood.

Associations of autozygosity with a broad range of human phenotypes

open access: yesNature Communications, 2019
Inbreeding depression has been observed in many different species, but in humans a systematic analysis has been difficult so far. Here, analysing more than 1.3 million individuals, the authors show that a genomic inbreeding coefficient (FROH) is ...
