(Springer Nature, 2017-04-25)Several copy number variants have been associated with neuropsychiatric disorders and these variants have been shown to also influence cognitive abilities in carriers unaffected by psychiatric disorders. Previously, we associated the 15q11.2(BP1–BP2) ... -
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04-13)The paper proposes a novel framework for accelerated re-design (dimension scaling) of antenna structures using inverse surrogates. The major contribution of the work is a sensitivity-based model identification procedure, which permits a significant ...

(Mary Ann Liebert Inc, 2019-08)Adolescent use of social media platforms such as Facebook, Instagram, and Snapchat has increased dramatically over the last decade and now pervades their everyday social lives. Active and passive social media use may impact emotional health differently, ...
-
(Public Library of Science (PLoS), 2018-12-26)Previous studies investigating the effects of transcranial direct current stimulation (tDCS) on muscle strength showed no consensus. Therefore, the purpose of this article was to systematically review the literature on the effects of single dose tDCS ...

(ACM, 2023-10-22)Cellular automata are an archetypical comonadic notion of computation in that computation happens in the coKleisli category of a comonad. In this paper, we show that they can also be viewed as graded comonadic—a perspective that turns out to be both ...
-
(MDPI AG, 2020-11-24)This study aimed to investigate the associations of competitive sport participation in adolescence and age at menarche (AAM) with body composition, femoral neck bone mineral density (BMD), physical performance, and physical activity (PA) in middle-aged ...
-
(Public Library of Science (PLoS), 2018-03-07)Sarcopenic muscular degeneration has been consistently identified as an independent risk factor for mortality in aging populations. Recent investigations have realized the quantitative potential of computed tomography (CT) image analysis to describe ...
-
(2023-03)Machine Learning (ML) is extensively used in diverse healthcare applications to aid physicians in diagnosing and identifying associations, sometimes hidden, between dif- ferent biomedical parameters. This PhD thesis investigates the interplay of ...
-
(2023-06)Crowd simulation focuses on modeling the movements and behaviors of large groups of people. This area of study has become increasingly important because of its several applications in various fields such as urban planning, safety, and entertainment. ...
-
(Springer, 2020)Monad algebras, turning computations over return values into values, are used to handle algebraic effects invoked by programs, whereas comonad coalgebras, turning initial states into environments (“cocomputations”) over states, describe production of ...
-
(Faculty of Kinesiology, University of Zagreb, 2018)The purpose of this study was to ascertain the pacing strategies employed in 10 km open water swimming events, and to define which split time was most determinant for the final performance as a function of sex and classification in International ...
-
(Elsevier BV, 2017-05)In addition to the mixing energy applied to the fresh concrete (i.e. shearing during mixing), the shear history after mixing is also important. This applies especially to binder rich concretes like the different types of high performance concrete (HPC). ...
-
(Háskólinn í Reykjavík, 2011-09-18)There are many open questions concerning the functioning of the human uterus. One of these open questions concerns exactly how the uterus operates as an organ to perform the very organized act of contracting in a synchronized fashion to expulse a new ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2020-05-27)Utilization of fast surrogate models has become a viable alternative to direct handling of full-wave electromagnetic (EM) simulations in EM-driven design. Their purpose is to alleviate the difficulties related to high computational cost of multiple ...
-
(2021-12-15)In the recent decade, marketing literature has acknowledged the advantages of applying an evolutionary lens to understand consumer behavior in different domains. Food choice context is one such domain, having implications for societal well-being, ...
-
(Háskólinn í Reykjavík, 2011-01-24)This thesis deals with approximation algorithms for the Maximum Independent Set and the Minimum Hitting Set problems on hypergraphs. As a hypergraph is a generalization of a graph, the question is whether the best known approximations on graphs can be ...
-
(BMJ, 2020-04-28)Objectives To compare the prevalence of different insomnia subtypes among middle-Aged adults from Europe and Australia and to explore the cross-sectional relationship between insomnia subtypes, respiratory symptoms and lung function. Design Cross-sectional ...
-
(Springer Science and Business Media LLC, 2020-02-18)The nonlinear trimodal regression analysis (NTRA) method based on radiodensitometric CT distributions was recently developed and assessed for the quantification of lower extremity function and nutritional parameters in aging subjects. However, the use ...
-
(2016-01)Liquid dominated reservoirs are a common type of hydrothermal reservoirs. They consist of fractured rock and reservoir fluid which may obey Darcy’s law. Steam can form in such reservoirs either through heat input which causes temperature increase or ...
-
(SAGE Publications, 2016-01-25)The life span approach to development provides a theoretical framework to examine the general principles of development across all ages (Baltes, Lindenberger, & Staudinger, 2006; Craik & Bialystok, 2006). Previously, developmental research has typically ...
