(Public Library of Science (PLoS), 2016-04-21)Vertebral fragility fractures are often treated by injecting bone cement into the collapsed vertebral bodies (vertebroplasty). The mechanisms by which vertebroplasty induces pain relief are not completely understood yet and recent debates cast doubt ... -
(American Physical Society (APS), 2016-02-09)We demonstrate that a spin-dependent Seebeck effect can be detected in quantum wells with zinc-blend structure with equal Rashba-Dresselhaus spin-orbit couplings. This theory is based on the establishment of an itinerant antiferromagnetic state, a low ...

(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 ...

(American Physical Society (APS), 2016-05-31)We analyze theoretically electronic transport through a core-shell nanowire in the presence of a transversal magnetic field. We calculate the conductance for a variable coupling between the nanowire and the attached leads and show how the snaking ...

(Walter de Gruyter GmbH, 2016-05-31)A simulation-based optimization approach to design of phase excitation tapers for linear phased antenna arrays is presented. The design optimization process is accelerated by means of Surrogate-Based Optimization (SBO); it uses a coarse-mesh surrogate ...
-
(Walter de Gruyter GmbH, 2016-12-13)Re-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various ...
-
(Polish Academy of Sciences, 2016-12-01)In this paper, a novel structure of a compact UWB slot antenna and its design optimization procedure has been presented. In order to achieve a sufficient number of degrees of freedom necessary to obtain a considerable size reduction rate, the slot is ...

(Springer Nature, 2017-10-14)The literature on sexual minority adolescents and young adults has highlighted a poor mental status among those groups compared to their heterosexual peers. Sexual minorities are also more likely to experience stress factors such as bullying and physical ...

(Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands, 2018-06-25)While half of undergraduate students in business are women, only one in five full professors in business in the US are female. According to the pipeline theory, this discrepancy should correct itself through time and more women join the ranks of full ...

(Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands, 2018-06-25)Previous studies have identified eight parameters as being the most influential on the Icelandic economy in the light of prevailing climate change. This study aims to investigate these economic parameters in relation to the Arctic Region and the Icelandic ...

(Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands, 2018-06-25)A persistent unexplained gender wage gap exists in Iceland and women are still in a minority as directors, chairs of boards and board members within organizations. Organizations are required by law to have a gender equality statement, but in addition ...

(Stofnun stjórnsýslufræða og stjórnmála við Háskóla Íslands, 2018-06-20)Í greininni er lagalegt umhverfi íþrótta á Íslandi kannað með hliðsjón af kynjajafnréttissjónarmiðum með hinni fræðilegu lagalegu aðferð (e. doctrinal method). Þannig eru skoðuð sjónarmið sem legið hafa til grundvallar lagasetningu um íþróttir, ...

(Exeley, Inc., 2018)Background: Studies on early intervention have reported significant gains for many children with autism. Knowledge on how these children fare in adulthood is limited. Objective: To examine long-term outcome of children with autism who received ...
-
(Wiley, 2017-12-20)To find sequence variants affecting prostate cancer (PCA) susceptibility in an unscreened Romanian population we use a genome‐wide association study (GWAS). The study population included 990 unrelated pathologically confirmed PCA cases and 1034 male ...
-
(American Chemical Society, 2018-04-21)The distinctive prismatic geometry of semiconductor core-shell nanowires leads to complex localization patterns of carriers. Here, we describe the formation of optically active in-gap excitonic states induced by the interplay between localization of ...
-
(Public Library of Science (PLoS), 2018-03-07)Sarcopenic muscular degeneration has been consistently identified as an independent risk factor for mortality in aging populations. Recent investigations have realized the quantitative potential of computed tomography (CT) image analysis to describe ...
-
(Stofnun stjórnsýslufræða og stjórnmála við Háskóla Íslands, 2017-12-14)The multinational retailer, Costco, opened its first store in Iceland during spring 2017. Not only was the opening greatly anticipated but following the store opening, Costco became one of the key issues in the Icelandic media. Our analysis focuses ...

(Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands, 2017-12-19)In conventional portfolio management returns are maximised subject to given risk levels. In this framework the only variables of relevance are risk and returns and their interrelationship as expressed in terms of the efficient frontier. It is increasingly ...

(Springer Nature, 2016-10-17)Studies assessing psychological treatment of attention deficit hyperactivity disorder (ADHD) in adults are increasingly reported. However, functional outcomes are often neglected in favour of symptom outcomes. We investigated functional outcomes in 95 ...

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 ...
