(IOP Publishing, 2018-05-31)We study the structure of the elementary excitations and their propagation in chiral hybrid structure, comprising an array of two-level systems (TLSs) coupled to a one-dimensional photonic waveguide. The chirality is achieved via spin-locking effect, ... -
(BMJ, 2017-08)Introduction Sleep length has been associated with obesity and various adverse health outcomes. The possible association of sleep length and respiratory symptoms has not been previously described. The aim of this study was to investigate the association ...

(Public Library of Science (PLoS), 2017-10-25)The limits of life of aerobic microorganisms are well understood, but the responses of anaerobic microorganisms to individual and combined extreme stressors are less well known. Motivated by an interest in understanding the survivability of anaerobic ...
-
(Springer Nature, 2017-08-15)Background There are an increasing number of studies regarding genetic manipulation of cyanobacteria to produce commercially interesting compounds. The majority of these works study the expression and optimization of a selected heterologous pathway, ...

(University of Iceland, School of Health Sciences, Faculty of Nursing, 2017-06)Purpose: Continuous peripheral pulse oximetry for monitoring adequacy of oxygenation is probably the most important technological advance for patients’ monitoring and safety in the last decades. Pulse oximetry has the disadvantage of measuring the ...
-
(Public Library of Science (PLoS), 2017-03-22)Background Determination of the blood oxyhemoglobin saturation in the retinal vessels of the eye can be achieved through spectrophotometric retinal oximetry which provides access to the state of oxyhemoglobin saturation in the central nervous system ...
-
(Public Library of Science (PLoS), 2016-02-03)Dual wavelength retinal oximetry has been developed for adults, but is not available for infants. Retinal oximetry may provide insight into the pathophysiology of oxygen-mediated diseases like retinopathy of prematurity. More insight in the oxygen ...
-
(Elsevier BV, 2018)Introduction We have previously reported that retinal vessel oxygen saturation is increased in mild-to-moderate dementia of Alzheimer's type when compared with healthy individuals. Mild cognitive impairment (MCI) is the predementia stage of the disease. ...
-
(Springer Science and Business Media LLC, 2020-09-21)The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer ...
-
(Crimson Publishers, 2022-02-23)This study aims to consider the Nominal Operating Cell Temperature (NOCT) model for the photovoltaic (PV) module by adding the wind effect via experiment equation. The resulting model presents a linear wind convection heat transfer equation; the PV ...
-
(Elsevier BV, 2019-05-13)Currently around 10% of all energy generated worldwide comes from biomass. Most of this 10% is biofuel energy from the fermentation of corn and sugarcane. Fermentation of corn competes with the global food supply, and fermentation of sugarcane drives ...
-
(Elsevier BV, 2020-11)Sustainable energy development has become an international policy objective and an integral part of sustainable development. It is necessary to develop a robust and comprehensive set of indicators to monitor progress towards sustainable energy development. ...
-
(Springer Nature, 2021-10-30)Morphometric analyses are based on multiparametric datasets that describe quantitatively the shapes of objects. The stochastic nature of fracture-formation processes that break up magma during explosive eruptions yields mixtures of particles that have ...
-
(Wiley, 2018-04-24)Aim: This review examined and summarised the research published on child abuse in Iceland, which was mainly in the country's native language, to make the findings more accessible to English speakers. It specifically focused on child rearing and the ...
-
Revisiting the Contested Role of Natural Resources in Violent Conflict Risk through Machine Learning (MDPI AG, 2020-08-14)The integrated character of the sustainable development goals in Agenda 2030, as well as research in environmental security, flag that sustainable peace requires sustainable and conflict-sensitive natural resource use. The precise relationship between ...
-
Revisiting the Mössbauer Isomer Shifts of the FeMoco Cluster of Nitrogenase and the Cofactor Charge (American Chemical Society (ACS), 2017-01-10)Despite decades of research, the structure–activity relationship of nitrogenase is still not understood. Only recently was the full molecular structure of the FeMo cofactor (FeMoco) revealed, but the charge and metal oxidation states of FeMoco have ...

Rifting Kinematics Produced by Magmatic and Tectonic Stresses in the North Volcanic Zone of Iceland (Frontiers Media SA, 2020-06-02)In the North Volcanic Zone of Iceland, we studied with the greatest possible detail the complete structural architecture and kinematics of the whole Theistareykir Fissure Swarm (ThFS), an N-S-trending, 70 km long active rift. We made about 7500 ...

(eLife Sciences Publications, Ltd, 2020-07-14)Losing a co-twin by death is a severely stressful event yet with unknown impact on the surviving twin’s risk of psychiatric disorders. We identified all Swedish-born twins who lost a cotwin by death between 1973 and 2013 (n = 4,528), their 4939 non-twin ...
-
(University of Iceland, School of Humanities, Faculty of History and Philosophy, 2018-05)In this thesis the ritual killing and burial of animals on grave-fields in Viking Age Iceland is critically re-evaluated, on a site-by-site basis, in order to characterize these customs and place them in a social and historical context. The foundation ...
