Complementation and Lebesgue-type decompositions of linear operators and relations
(John Wiley & Sons, 15.04.2024)
articleIn this paper, a new general approach is developed to construct and study Lebesgue-type decompositions of linear operators or relations T in the Hilbert space setting. The new approach allows to introduce an essentially ... -
Decomposition formula for rough Volterra stochastic volatility models
(World Scientific Publishing Company, 14.04.2021)
articleThe research presented in this paper provides an alternative option pricing approach for a class of rough fractional stochastic volatility models. These models are increasingly popular between academics and practitioners ... -
Diagnostic accuracy of contrast-enhanced CT for neck abscesses : A systematic review and meta-analysis of positive predictive value
(Public Library of Science, 26.10.2022)
articleObjectives To review the diagnostic accuracy of contrast-enhanced computed tomography (CT) in differentiating abscesses from cellulitis in patients with neck infections, using surgical findings as the reference ... -
Diagnostic Accuracy of MRI in Detecting the Perineural Spread of Head and Neck Tumors : A Systematic Review and Meta-Analysis
(MDPI, 04.01.2024)
articleThe purpose of this study was to review the diagnostic accuracy of MRI in detecting perineural spreading (PNS) of head and neck tumors using histopathological or surgical evidence from the afflicted nerve as the reference ... -
Diagnostic performance of short noncontrast biparametric 3‑T MRI for tonsillar infections : comparison with a full protocol including contrast‑enhanced sequence
(Springer, 24.10.2023)
articleBackground We investigated whether a short, 5-min magnetic resonance imaging (MRI) protocol consisting of only axial T2-weighted and diffusion-weighted imaging (DWI) sequences can discriminate between tonsillar infections, ... -

Effects of single family room architecture on parent-infant closeness and family centered care in neonatal environments : a single-center pre-post study
(Springer Nature, 06.07.2021)
articleOBJECTIVE: The aim of this study was to evaluate the effects of a single family room architecture in a neonatal intensive care unit (SFR-NICU) on parents’ presence, parent–infant skin-to-skin contact (SSC) and the quality ... -
Equity Warrants Pricing Formula for Uncertain Financial Market
(MDPI, 22.02.2022)
articleIn this paper, inside the system of uncertainty theory, the valuation of equity warrants is explored. Different from the strategies of probability theory, the valuation problem of equity warrants is unraveled by utilizing ... -
Fewer maternal depression symptoms after the Close Collaboration with Parents intervention : Two-year follow-up
(Wiley, 18.02.2022)
articleAim To test whether the implementation of the Close Collaboration with Parents intervention at a neonatal intensive care unit (NICU) decreases depression symptoms of mothers up to two years after the delivery of preterm ... -
Financial crises and the asymmetric relation between returns on banks, risk factors, and other industry portfolio returns
(Wiley, 29.01.2021)
articleWe show that the relations between the returns on the banking industry, risk factors, and other industries often are asymmetric. Lagged banking industry returns seem to improve predictability but the positive impact of a ... -
Forecasting the Finnish house price returns and volatility : a comparison of time series models
(Emerald, 11.04.2021)
articlePurpose The purpose of this paper is to compare different models’ performance in modelling and forecasting the Finnish house price returns and volatility. Design/methodology/approach The competing models are the ... -

(Wiley, 12.05.2022)
articleThe paper is a continuation of Part I and contains several further results on generalized boundary triples, the corresponding Weyl functions, and applications of this technique to ordinary and partial differential operators. ... -
Generalized Schur Functions as Multivalent Functions
(Springer, 14.01.2021)
articleThe multivalency approach to generalized Nevanlinna functions established in Wietsma (Indag Math 29:997–1008, 2018) is here extended to the related class of generalized Schur functions giving thereby rise to new characterizations ... -
Health-Related Quality of Life Outcomes of Instrumented Circumferential Spinal Fusion for Pediatric Spondylolisthesis : A Comparison With Age and Sex Matched Healthy Controls
(Lippincott, Williams & Wilkins, 01.12.2020)
articleStudy Design. A prospective study on the clinical, radiographic, and the health-related quality of life (HRQOL) outcomes in adolescents with spondylolisthesis undergoing instrumented circumferential spinal fusion compared ... -
Lebesgue type decompositions and Radon–Nikodym derivatives for pairs of bounded linear operators
(Springer, 01.09.2022)
articleFor a pair of bounded linear Hilbert space operators A and B one considers the Lebesgue type decompositions of B with respect to A into an almost dominated part and a singular part, analogous to the Lebesgue decomposition ... -
