(IOP Publishing, 2017-08-23)Solid state physics (SSP) research at ISOLDE has been running since the mid-1970s and accounts for about 10%–15% of the overall physics programme. ISOLDE is the world flagship for the on-line production of exotic radioactive isotopes, with high yields, ... -
(Springer Nature, 2017-09-07)Growing evidence for significant magmatic vesiculation prior to magma-water interaction (MWI) has brought into question the use of ‘diagnostic’ features, such as low vesicularities and blocky morphologies, to identify hydromagmatic pyroclasts. We address ...

(Informa UK Limited, 2018-01-23)The purpose of this article is analysis of discursive marginalisation through education in Nordic welfare states. What knowledge do Nordic research discourses produce about marginalisation through education in Nordic welfare states? What are the ...

(Elsevier BV, 2017-03)The conformational preference of the cyano group of the 1-cyano-1-silacyclohexane was studied experimentally by means of gas electron diffraction (GED) and dynamic nuclear magnetic resonance (DNMR) as well as by quantum chemical (QC) calculations ...
-
(Félag áhugamanna um heimspeki, 2017)Analytic philosophy has for a long time had the image of not being a field where social criticism is practiced. Instead, it gives the impression of putting all the emphasis on abstract concepts that have little or no application to current affairs. In ...

Origins of the Greenland shark (Somniosus microcephalus): Impacts of ice-olation and introgression (Wiley-Blackwell, 2017-09-08)erein, we use genetic data from 277 sleeper sharks to perform coalescent-based modeling to test the hypothesis of early Quaternary emergence of the Greenland shark (Somniosus microcephalus) from ancestral sleeper sharks in the Canadian Arctic-Subarctic ...

(MDPI AG, 2017-10-21)In Iceland, there is a large variation in daylight between summer and winter. The aim of the study was to identify how this large variation influences physical activity (PA) and sedentary behavior (SB). Free living PA was measured by a waist-worn ...
-
(MDPI AG, 2017-10-05)Climate change mitigation is an important goal for cities globally. Energy production contributes more than half of the global greenhouse gas emissions, and thus the mitigation potential of local municipal energy systems is important for cities to ...
-
(Springer Nature, 2017-10)Within gauge/gravity duality, we consider the local quench-like time evolution obtained by joining two 1+1-dimensional heat baths at different temperatures at time t = 0. A steady state forms and expands in space. For the 2+1-dimensional gravity dual, ...

(Springer Nature, 2017-10-10)Background: Ixodes ricinus is a three-host tick, a principal vector of Borrelia burgdorferi (s.l.) and one of the main vectors of tick-borne encephalitis (TBE) virus. Iceland is located in the North Atlantic Ocean with subpolar oceanic climate. During ...

Examining the link between maternal nutrition, gestational weight gain, and later offspring health (University of Iceland, School of Health Sciences, Faculty of Food Science and Nutrition, 2018-01)Aim: The aim of this Ph.D. thesis is to enhance understanding of the relation between maternal diet, gestational weight gain (GWG), and offspring’s cardio-metabolic factors. Moreover, the objective is to identify dietary predictors for excessive GWG. ...
-
(American Physical Society (APS), 2017-10-10)We show for a simple noncollinear configuration of the atomistic spins (in particular, where one spin is rotated by a finite angle in a ferromagnetic background) that the pairwise energy variation computed in terms of multiple-scattering formalism ...
-
(American Physical Society (APS), 2017-12-13)A coupled atomistic spin and lattice dynamics approach is developed which merges the dynamics of these two degrees of freedom into a single set of coupled equations of motion. The underlying microscopic model comprises local exchange interactions between ...
-
(Elsevier BV, 2017-09)The stability of magnetic skyrmions against thermal fluctuations and external perturbations is investigated within the framework of harmonic transition state theory for magnetic degrees of freedom. The influence of confined geometry and atomic scale ...
-
(Elsevier BV, 2017-11)The stability of skyrmions in various environments is estimated by analyzing the multidimensional surface describing the energy of the system as a function of the directions of the magnetic moments in the system. The energy is given by a Heisenberg-like ...
-
(American Physical Society (APS), 2017-04-24)Rohart et al. [Phys. Rev. B 93, 214412 (2016)] recently reported calculations indicating two mechanisms for the annihilation of a skyrmion in a Co monolayer on Pt(111). The path calculations were based on a method presented in the Supplemental Material ...
-
(Elsevier BV, 2017-07)Point-to-point ray tracing is an important problem in many fields of science. While direct variational methods where some trajectory is transformed to an optimal one are routinely used in calculations of pathways of seismic waves, chemical reactions, ...
-
(Wiley-Blackwell, 2018-01-03)The early stages of intraspecific diversity are important for the evolution of diversification and speciation. Early stages of diversification can be seen in individual specialization, where individuals consume only a portion of the diet of the population ...

Enumerations of Permutations Simultaneously Avoiding a Vincular and a Covincular Pattern of Length 3 (University of Waterloo, 2017)Vincular and covincular patterns are generalizations of classical patterns allowing restrictions on the indices and values of the occurrences in a permutation. In this paper we study the integer sequences arising as the enumerations of permutations ...

(Public Library of Science (PLoS), 2017-10-12)Marine Protected Areas (MPA) are important management tools shown to protect marine organisms, restore biomass, and increase fisheries yields. While MPAs have been successful in meeting these goals for many relatively sedentary species, highly mobile ...
