(American Chemical Society (ACS), 2018-02-12)We propose an experimentally friendly scheme for trapping quasi-relativistic electrons in graphene by an electromagnetic beam with circular polarization and a spatially inhomogeneous profile with an intensity dip. The trapping is achieved due to the ... -
(American Physical Society (APS), 2017-10-11)It is shown theoretically that the renormalization of the electron energy spectrum of bilayer graphene with a strong high-frequency electromagnetic field (dressing field) results in the Lifshitz transition—the abrupt change in the topology of the Fermi ...

Optimal atomic structure of amorphous silicon obtained from density functional theory calculations (IOP Publishing, 2017-06-15)Atomic structure of amorphous silicon consistent with several reported experimental measurements has been obtained from annealing simulations using electron density functional theory calculations and a systematic removal of weakly bound atoms. The ...

(American Physical Society (APS), 2021-04-29)A complete analytical solution to the optimal reversal of a macrospin with easy-axis anisotropy is presented. An optimal control path minimizing the energy cost of the reversal is identified and used to derive the time-dependent direction and amplitude ...
-
(American Physical Society (APS), 2022-04-07)It is demonstrated by means of the optimal control theory that the energy cost of the spin-orbit torque induced reversal of a nanomagnet with perpendicular anisotropy can be strongly reduced by proper shaping of both in-plane components of the current ...

(Public Library of Science (PLoS), 2017-08-30)Background Type 2 diabetes and prediabetes are established risk factors for atherosclerosis. The aim of this study was to evaluate the atherosclerotic plaque burden in the carotid arteries of patients with acute coronary syndrome according to their ...
-
(BMJ, 2019-01)Introduction Intervention studies have mainly used oral nutritional supplements (ONS) for the management of patients with chronic obstructive pulmonary disease (COPD) identified as at nutritional risk. In this 12-month randomised feasibility trial, we ...

(The Educational Research Institute, 2020-07-13)Tilgangur rannsóknarinnar var að bera saman áhrif beinnar og óbeinnar orðaforðakennslu hjá börnum með málþroskaröskun. Einkenni málþroskaröskunar er slök færni í tungumálinu, bæði í málskilningi og máltjáningu. Beina orðaforðakennslan fólst í að ...

(Menntavísindasvið, Menntavísindastofnun Háskóla Íslands, 2018-12-31)Greinin fjallar um orðaforðahluta rannsóknar á þróun máls og læsis meðal íslenskra barna á aldrinum 4 til 8 ára. Um er að ræða viðamikla langtímarannsókn á flestum þáttum málþroska og tengslum hans við þróun læsis og félagsþroska. Til að bæta úr skorti ...
-
(SAGE Publications, 2017-06-30)Aims: The aims of this study were to study the correlation between lifestyle-related factors, such as organized leisure-time sport participation (OLSP), cardiorespiratory fitness, and adiposity, and academic achievement among preadolescents. Methods: ...

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 ...

(Institute of Technology and Vocational Education, Graduate School of Education and Human Development, Nagoya University, 2015-10-31)Pedagogically aimed craft education, or Sloyd, was established in Scandinavia at the close of the 19th century as a specific subject to be included in general education. The term Sloyd means skilful or handy and refers to the making of crafts (Chessin, ...

(Wiley, 2018-11-05)A novel viral haemorrhagic septicaemia virus (VHSV) of genotype IV was isolated from wild lumpfish (Cyclopterus lumpus), brought to a land-based farm in Iceland, to serve as broodfish. Two groups of lumpfish juveniles, kept in tanks in the same facility, ...
-
(Ferrata Storti Foundation (Haematologica), 2017-12-07)Epidemiology and outcome of myeloma are mainly reported from large university centers and collaborative groups, and do not represent ‘real-world’ patients. The Swedish Myeloma Registry is a prospective population-based registry documenting characteristics, ...
-
(MDPI AG, 2020-09-08)Iceland has been one of the main destinations that have been incorporated into the discourse of overtourism. However, Iceland is different to many other supposed overtourism destinations in that its tourism is based on natural areas. Nevertheless, ...
-
(Elsevier BV, 2019-05)Both intact and deficient neural processing of faces has been found in dyslexic readers. Similarly, behavioral studies have shown both normal and abnormal face processing in developmental dyslexia. We tested whether dyslexic adults are impaired in tests ...

(Hugvísindastofnun Háskóla Íslands, 2018-09-05)Einn þekktasti lofsöngur um höfuðborg Íslands, Reykjavík, er án efa kvæðið „Ó borg, mín borg“, eftir Vilhjálm frá Skáholti, sem Haukur Morthens gerði ódauðlegt um miðja síðustu öld. Til að veita því fjölmenningarlega samfélagi sem nú blómstrar á Íslandi ...

(Menntavísindastofnun Háskóla Íslands, 2018-12-31)Í Laxdælu fléttast saman margir þræðir. Sumir eru næstum eins og sjálfstæðar frásagnir inni í stærri framvindu. Þessi flókna saga er alloft notuð sem kennsluefni við grunnskóla og framhaldsskóla. Eitt af vandamálum kennara sem kynna hana fyrir unglingum ...

(Menntavísindastofnun, Menntavísindasvið, Háskóli Íslands, 2020-01-28)Greinin fjallar annars vegar um þá miklu áherslu sem lögð er á notkun gagna í skólastarfi og hins vegar um það að þau gefi litla leiðsögn í mikilvægum efnum. Umfang og margbreytileiki gagna vex hratt og margir ólíkir heimar gagna sem tengjast menntun ...
