Variation in breeding practices and geographic isolation drive subpopulation differentiation, contributing to the loss of genetic diversity within dog breed lineages
(Springer Science and Business Media LLC, 2020)Background Discrete breed ideals are not restricted to delimiting dog breeds from another, but also are key drivers of subpopulation differentiation. As genetic differentiation due to population fragmentation results in ...Tieteelliset aikakauslehtiartikkelit

Verbalization has regulatory influences on autonomic activity during recall of unpleasant experience
(Elsevier BV, 2021)The purpose of the study was to examine effects of verbalization of affective experience on heart-rate variability and emotions (HRV). We measured HRV of 35 subjects while they were viewing and verbalizing 48 affective ...Tieteelliset aikakauslehtiartikkelit

Very early osteoarthritis changes sensitively fluid flow properties of articular cartilage
(Elsevier BV, 2015)In this study, fibril-reinforced poroelastic (FRPE) modeling was used for rabbit knee after anterior cruciate ligament transection (ACLT) to assess how the mechanical properties of collagen, proteoglycans, and fluid in ...info:eu-repo/semantics/article

Visualizing Overlapping Biclusterings and Boolean Matrix Factorizations
(Springer Nature Switzerland AG, 2023)Finding (bi-)clusters in bipartite graphs is a popular data analysis approach. Analysts typically want to visualize the clusters, which is simple as long as the clusters are disjoint. However, many modern algorithms find ...

Voice biometrics security: Extrapolating false alarm rate via hierarchical Bayesian modeling of speaker verification scores
(Elsevier BV, 2019)How secure automatic speaker verification (ASV) technology is? More concretely, given a specific target speaker, how likely is it to find another person who gets falsely accepted as that target? This question may be addressed ...Tieteelliset aikakauslehtiartikkelit

Volatile Organic Compounds from Logwood Combustion: Emissions and Transformation under Dark and Photochemical Aging Conditions in a Smog Chamber
(American Chemical Society (ACS), 2018)Residential wood combustion (RWC) emits high amounts of volatile organic compounds (VOCs) into ambient air, leading to formation of secondary organic aerosol (SOA), and various health and climate effects. In this study, ...Tieteelliset aikakauslehtiartikkelit

Volatility of mixed atmospheric humic-like substances and ammonium sulfate particles
(Copernicus Publications on behalf of the European Geosciences Union, 2017)The volatility of organic aerosols remains poorly understood due to the complexity of speciation and multiphase processes. In this study, we extracted humic-like substances (HULIS) from four atmospheric aerosol samples ...info:eu-repo/semantics/article

Volcanic dust veils from sixth century tree-ring isotopes linked to reduced irradiance, primary production and human health
(Springer Nature, 2018)The large volcanic eruptions of AD 536 and 540 led to climate cooling and contributed to hardships of Late Antiquity societies throughout Eurasia, and triggered a major environmental event in the historical Roman Empire. ...Tieteelliset aikakauslehtiartikkelit
