Freezing tolerance of seeds can explain differences in the distribution of two widespread mistletoe subspecies in Europe
(Elsevier BV, 2021)The ability of plants to tolerate freezing limits their geographical distribution. Therefore, winter warming may shift a species’ occurrence northwards and/or to higher altitudes. In Europe, the hemiparasitic vascular plant ...Tieteelliset aikakauslehtiartikkelit

Functional Effects of an Interpenetrating Polymer Network on Articular Cartilage Mechanical Properties
(Elsevier BV, 2018)Objective Depletion of glycosaminoglycans (GAGs) and degradation of collagen network are early hallmarks of osteoarthritis (OA). Currently, there are no chondroprotective therapies that mitigate the loss of GAGs or ...Tieteelliset aikakauslehtiartikkelit

Functionalization of polymers and nanomaterials for water treatment, food packaging, textile and biomedical applications: a review
(Springer Nature, 2021)The inert nature of most commercial polymers and nanomaterials results in limitations of applications in various industrial fields. This can be solved by surface modifications to improve physicochemical and biological ...

Further optimisations of constant Q cepstral processing for integrated utterance and text-dependent speaker verification
(Institute of Electrical and Electronics Engineers (IEEE), 2016)Many authentication applications involving automatic speaker verification (ASV) demand robust performance using short-duration, fixed or prompted text utterances. Text constraints not only reduce the phone-mismatch between ...conferenceObject

Fusing diameter distributions predicted by an area-based approach and individual-tree detection in coniferous-dominated forests
(Canadian Science Publishing, 2019)An area-based approach (ABA) is the most common method used to predict forest attributes with airborne laser scanning (ALS) data. Individual-tree detection (ITD) offers an alternative to ABA; however, few studies have ...Tieteelliset aikakauslehtiartikkelit

Gamete-level immunogenetic incompatibility in humans - towards deeper understanding of fertilization and infertility?
(Springer Science and Business Media LLC, 2020)Human leukocyte antigen (HLA) immune genes play an important role in partner selection, but it has remained unclear if nonrandom pairing with respect to parental HLA genes could occur at the level of the gametes. We tested ...Tieteelliset aikakauslehtiartikkelit

Gamma Power of Electroencephalogram Arousal is Modulated by Respiratory Event Type and Severity in Obstructive Sleep Apnea
(IEEE, 2022)Objective: We aimed to investigate the differences in electroencephalogram (EEG) gamma power (30–40 Hz) of respiratory arousals between varying types and severities of respiratory events, and in different sleep stages. ...

Gammaproteobacterial methanotrophs dominate methanotrophy in aerobic and anaerobic layers of boreal lake waters
(Inter-Research Science Center, 2018)Small oxygen-stratified humic lakes of the boreal zone are important sources of methane to the atmosphere. Although stable isotope profiling has indicated that a substantial part of methane is already oxidized in the ...Tieteelliset aikakauslehtiartikkelit

Gas-to-Particle Partitioning of Cyclohexene- and α-Pinene-Derived Highly Oxygenated Dimers Evaluated Using COSMOtherm
(American Chemical Society (ACS), 2021)Oxidized organic compounds are expected to contribute to secondary organic aerosol (SOA) if they have sufficiently low volatilities. We estimated saturation vapor pressures and activity coefficients (at infinite dilution ...Tieteelliset aikakauslehtiartikkelit

Generalization of Pólya's Zero Distribution Theory for Exponential Polynomials, and Sharp Results for Asymptotic Growth
(Springer Science and Business Media LLC, 2021)An exponential polynomial of order q is an entire function of the form f(z)=P1(z)eQ1(z)+⋯+Pk(z)eQk(z), where the coefficients Pj(z),Qj(z) are polynomials in z such that max{deg(Qj)}=q. In 1977 Steinmetz proved that the ...Tieteelliset aikakauslehtiartikkelit
