(Elsevier BV, 2019-02)MicroRNAs regulate developmental events such as branching morphogenesis, epithelial to mesenchymal transition (EMT) and its reverse process mesenchymal to epithelial transition (MET). In this study, we performed small RNA sequencing of a breast epithelial ... -
(Menntavísindasvið Háskóli Íslands, 2016)Athugun á niðurstöðum í stærðfræði í PISA-rannsókninni 2003 sýndi að árangur nemenda í tveimur stærstu skólunum var marktækt betri en í minni skólum. Sérstaklega var árangurinn slakur í skólum með 11–25 þátttakendur. Athugun á árangri í dönskum skólum ...

(Springer Science and Business Media LLC, 2019-01-31)The MITF transcription factor is a master regulator of melanocyte development and a critical factor in melanomagenesis. The related transcription factors TFEB and TFE3 regulate lysosomal activity and autophagy processes known to be important in ...
-
(The Company of Biologists, 2015-06-19)The v-ATPase is a fundamental eukaryotic enzyme that is central to cellular homeostasis. Although its impact on key metabolic regulators such as TORC1 is well documented, our knowledge of mechanisms that regulate v-ATPase activity is limited. Here, we ...

(Informa UK Limited, 2019-01-08)The complete mitogenome of Buccinum undatum obtained from transcriptome analysis is presented here. The mitogenome is 15,265 bp in length and comprises 13 protein-coding genes, 2 ribosomal subunit genes, and 22 transfer RNAs. The complete genome was ...
-
(Cambridge University Press (CUP), 2017)A two-dimensional theory of adolescent coping with cross-cultural and cross-Human Development Index Categories (HDI) application was tested: the Measure of Adolescent Coping Strategies (MACS). The MACS was answered by 809 adolescents of diverse origins ...
-
(Royal Society of Chemistry (RSC), 2019-10-15)Molybdenum nitrogenase is one of the most intriguing metalloenzymes in nature, featuring an exotic iron-molybdenum-sulfur cofactor, FeMoco, whose mode of action remains elusive. In particular, the molecular and electronic structure of the N2-binding ...
-
(American Chemical Society (ACS), 2019-02-18)Afterglow is an important phenomenon in luminescent materials and can be desired (e.g., persistent phosphors) or undesired (e.g., scintillators). Understanding and predicting afterglow is often based on analysis of thermally stimulated luminescence ...
-
(2018-06)In the recent years, formal modeling and verification of realtime systems have become very important. Difficult-to-use modeling languages and inefficient analysis tools are the main obstacles to use formal methods in this domain. Timed actor model is ...
-
(Copernicus GmbH, 2018-01-19)Glaciers with extensive surface debris cover respond differently to climate forcing than those without supraglacial debris. In order to include debris-covered glaciers in projections of glaciogenic runoff and sea level rise and to understand the ...
-
(Language Centre – University of Cyprus, 2018)The present article deals with the development of basic linguistic terminology in Icelandic. Such terminology pertains to five categories (general, graphematics, phonetics, morphology and lexicon) and has been collected from 19 different sources from ...
-
(Elsevier BV, 2019-06-15)Molards have been defined in the past as conical mounds of debris that can form part of a landslide's deposits. We present the first conclusive evidence that molards in permafrost terrains are cones of loose debris that result from thawing of frozen ...
-
(IOP Publishing, 2016-08)The hybrid graphene - hexagonal boron nitride (G-hBN) systems offer new routes in the design of nanoscale electronic devices. Using ab initio density functional theory calculations we investigate the dynamics of zig-zag nanoribbons a few interatomic ...
-
(ArXiv, 2016-08)High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission from a prolate spheroidal tip. The space charge limited current is several times lower than the current calculated with ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017)Molybdenum isotopes are used to quantify changes in Earth’s paleoredox conditions but their application relies upon a simplified model in which rivers dominate the ocean input with minor contributions from hydrothermal fluids. The effect of groundwater ...
-
(Acta Universitatis Upsaliensis, 2015)Domestic animals have rich phenotypic diversity that can be explored to advance our understanding of the relationship between molecular genetics and phenotypic variation. Since the advent of second generation sequencing, it has become easier to ...
-
(HERMES History Education Research Network, 2017-01-18)In this article I attempt to answer the question - is there is a conceptual link between moral and historical consciousness? I shall first discuss moral concepts and moral development; try to explore what they mean, and what they involve. In doing ...

(Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands., 2010)Þessi grein fjallar um áhrif uppgangs íslenska útrásarhagkerfisins og hruns fjármálakerfisins í kjölfarið á ýmsa eignamarkaði og eigna- og tekjuskiptingu í landinu. Dregið er fram að áhrifin af eignaverðsbólunni eru um margt svipuð og í Ponzi-leik þar ...
