Detection of selection signatures in South African Mutton Merino sheep using whole-genome sequencing data.

Animal Genetics, 2022
The South African Mutton Merino (SAMM), a dual-purpose (meat and wool) sheep breed, is characterized by its excellent performance on growth, carcass traits and meat quality compared to other fine-wool Merino breeds.

Selection signatures in Shetland ponies

Animal Genetics, 2016
SummaryShetland ponies were selected for numerous traits including small stature, strength, hardiness and longevity. Despite the different selection criteria, Shetland ponies are well known for their small stature. We performed a selection signature analysis including genome‐wide SNPs of 75 Shetland ponies and 76 large‐sized horses.

Machine-Learning Prospects for Detecting Selection Signatures Using Population Genomics Data

J. Comput. Biol., 2022
Natural selection has been given a lot of attention because it relates to the adaptation of populations to their environments, both biotic and abiotic. An allele is selected when it is favored by natural selection.

Spectral Signatures of Saccade Target Selection

Brain Topography, 2015
Action generation relies on a widely distributed network of brain areas. However, little is known about the spatiotemporal dynamics of neuronal activity in the network that gives rise to voluntary action in humans. Here, we used magnetoencephalography (MEG) and source analysis (n = 15, 7 female subjects) to investigate the spectral signatures of human ...

Genetic diversity and selection signatures of four indigenous pig breeds from eastern China.

Animal Genetics, 2022
Chinese indigenous pig breeds have been undergoing selection for thousands of years, and have become invaluable genetic sources over the world. To investigate the population structure and genetic diversity of Jinhua (JH), Longyou Black (LYW), Shengxian ...

Selection of reference signatures for automatic signature verification

Proceedings of the Fifth International Conference on Document Analysis and Recognition. ICDAR '99 (Cat. No.PR00318), 1999
This paper presents an effective procedure to select the reference specimens for a signature verification system. Specifically, from the analysis of local stability in handwritten signatures, a suitable measure is proposed to determine the capability of different sets of signatures in supporting effective verification.

A Signature Complexity Measure to Select Reference Signatures for Online Signature Verification

2015 International Conference of the Biometrics Special Interest Group (BIOSIG), 2015
This paper presents an original procedure for selecting the reference online signature instances of a writer, an important issue for any effective signature verifier. To this end, for each signature instance, we propose a novel complexity measure, by exploiting a global description of signatures in the frequency domain as well as a global statistical ...

Genomic inbreeding and selection signatures in the local dairy breed Icelandic Cattle.

Animal Genetics, 2021
Icelandic Cattle is the only dairy cattle breed native to Iceland. It currently numbers ca. 26 000 breeding females. We used 50k genotypes of over 8000 Icelandic Cattle to estimate genomic and pedigree-based inbreeding and to detect selection signatures ...

A selection signatures study among Middle Eastern and European sheep breeds.

Journal of animal breeding and genetics = Zeitschrift fur Tierzuchtung und Zuchtungsbiologie, 2021
Selection, both natural and artificial, leaves patterns on the genome during domestication of animals and leads to changes in allele frequencies among populations. Detecting genomic regions influenced by selection in livestock may assist in understanding

Time-Selective Convertible Undeniable Signatures

2005
Undeniable signatures were introduced in 1989 by Chaum and van Antwerpen to limit the self-authenticating property of digital signatures. An extended concept – the convertible undeniable signatures – proposed by Boyar, Chaum, Damgard and Pedersen in 1991, allows the signer to convert undeniable signatures to ordinary digital signatures.
