(Springer Nature, 2017-01-19)Background Preterm delivery increases the risk of neonatal morbidity and mortality. Studies suggest that maternal diet may affect the prevalence of preterm delivery. The aim of this study was to assess whether maternal intakes of seafood and marine ... -
(Springer Nature, 2017-01-25)Quartz is a common phase in high-silica igneous rocks and is resistant to post-eruptive alteration, thus offering a reliable record of magmatic processes in silicic magma systems. Here we employ the 75 ka Toba super-eruption as a case study to show ...

(Association for Research in Vision and Ophthalmology (ARVO), 2017-02-28)We recently demonstrated that observers are capable of encoding not only summary statistics, such as mean and variance of stimulus ensembles, but also the shape of the ensembles. Here, for the first time, we show the learning dynamics of this process, ...

(Institute of Electrical and Electronics Engineers (IEEE), 2017)We present, in this paper, a new methodology for spectral unmixing, where a vector of fractions, corresponding to a set of endmembers (EMs), is estimated for each pixel in the image. The process first provides an initial estimate of the fraction vector, ...

(University of Iceland, Faculty of Life and Environmental Sciences, 2017-05)The parasite fauna of the Icelandic rock ptarmigan Lagopus muta had just been described when engaging in this project in 2010. Purpose was to study the influence that parasites exhibit on ptarmigan population change over a period of 7 years (2006–2012). ...
-
(Springer Nature, 2017-02-27)Remnants of cities and farmlands in China’s hyperarid Tarim Basin indicate that environmental conditions were significantly wetter two millennia ago in a region which is barren desert today. Historical documents and age data of organic remains show ...
-
(Acta Dermato-Venereologica, 2017)Psoriasis is a chronic inflammatory skin disease with profound effects on patients’ health-related quality of life (HRQoL). Twenty-nine patients with plaque psoriasis and a history of streptococcal-associated psoriasis exacerbations were randomly ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2017-06)Lung cancer is the third most common type of cancer and the prime cause of cancer-related deaths in Iceland. As surgical resection is the only well-defined and well-studied curative treatment, the aim is to offer surgery to as many patients as possible ...

(MDPI AG, 2017-01-16)GRB 130427A was the most luminous gamma-ray burst detected in the last 30 years. With an isotropic energy output of 8.5 x 10(53) erg and redshift of 0.34, it combined very high energetics with a relative proximity to Earth in an unprecedented way. ...
-
(Public Library of Science (PLoS), 2017-03-01)Background Dietary habits are linked to high maternal glucose levels, associated with preterm delivery. The aim of this study was to examine the associations between meal frequency and glycemic properties of maternal diet in relation to preterm ...
-
Detection and Selection of Behavioral Patterns Using Theme: A Concrete Example in Grassroots Soccer (MDPI AG, 2017-03-13)Observational methodology provides a rigorous yet flexible framework for capturing behaviors over time to allow for the performance of subsequent diachronic analyses of the data captured. Theme is a specialized software program that detects hidden ...
-
(Wiley-Blackwell, 2017-02)The importance of environmental disturbances as drivers of ecological communities depends not only on the magnitude of the disturbance, but also on the disturbance-specific sensitivity of the community. Organisms that alter the physical structure of ...
-
(Springer Nature, 2017-02)Boundary correlation functions provide insight into the emergence of an effective geometry in higher spin gravity duals of O(N ) or U(N ) symmetric field theories. On a compact manifold, the singlet constraint leads to nontrivial dynamics at finite ...
-
(Springer Nature, 2017-03-08)Background: The article explores the significance of abundant geothermal resources Icelanders enjoy, the comfort of inexpensively heated homes and easily accessible year-round public spaces where young and old can gather irrespective of social standing, ...
-
(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 ...
-
(Springer Nature, 2017-03)In the context of applications of the AdS/CFT correspondence to condensed matter physics, we compute conductivities for field theory duals of dyonic planar black holes in 3+1-dimensional Einstein-Maxwell-dilaton theories at zero temperature. We ...
-
(Copernicus GmbH, 2017-03-23)Deposition of small amounts of airborne dust on glaciers causes positive radiative forcing and enhanced melting due to the reduction of surface albedo. To study the effects of dust deposition on the mass balance of Brúarjökull, an outlet glacier of the ...
-
(MDPI AG, 2017-03-17)Aerial image classification has become popular and has attracted extensive research efforts in recent decades. The main challenge lies in its very high spatial resolution but relatively insufficient spectral information. To this end, spatial-spectral ...
-
(Språk och litteraturcentrum (Lunds universitet), 2016)This article examines aspects of Icelandic linguistic purism in the early 18th century, as revealed in a wordlist compiled by Jón Ólafsson from Grunnavík (1705–1779) and preserved in ms. AM 1013 4to (fol. 37v). After a brief introduction (§ 1), there ...

(Cambridge University Press (CUP), 2017-01-25)We assess ice loss and velocity changes between 1985 and 2014 of three tidewater and fiveland terminating glaciers in Godthabsfjord (Nuup Kangerlua), Greenland. Glacier thinning accounted for 43.8 +/- 0.2 km(3) of ice loss, equivalent to 0.10 mm eustatic ...
