    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 ...

    Understanding of sequence diversity is the cornerstone of analysis of genetic disorders, population genetics, and evolutionary biology. Here, we present an update of our sequencing set to 15,220 Icelanders who we sequenced to an average genome-wide ...
  • Sitek, Anna; Ţolea, Mugurel; Niţă, Marian; Serra, Llorenç; Gudmundsson, Vidar; Manolescu, Andrei (Springer Nature, 2017-01-10)
    We study Coulomb interacting electrons confined in polygonal quantum rings. We focus on the interplay of localization at the polygon corners and Coulomb repulsion. Remarkably, the Coulomb repulsion allows the formation of in-gap states, i.e., ...
  • Bordbar, Aarash; Yurkovich, James T.; Paglia, Giuseppe; Rolfsson, Óttar; Sigurjónsson, Ólafur E.; Palsson, Bernhard O. (Springer Nature, 2017-04-07)
    The increasing availability of metabolomics data necessitates novel methods for deeper data analysis and interpretation. We present a flux balance analysis method that allows for the computation of dynamic intracellular metabolic changes at the cellular ...

    Staðgöngubjagi stafar af því að neysluhegðun breytist frá þeim tíma sem líður frá því að vogir neyslukörfu eru metnar og fram að notkun hennar við verðbólgumælingu. Neyslukannanir sem liggja til grundvallar mati á vogum 2/3 hluta neyslukörfunnar eru ...
  • Baldursson, Friðrik Már; Hall, Axel (Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands., 2008)
    Inflation scenarios in forecasts of the Central Bank of Iceland (CBI) appear to converge to the inflation target (2.5%) in 8-9 quarters. We ask whether this is a coincidence or an inherent property of the CBI’s model, QMM. We formulate a sub-model, ...
  • Einarsdottir, Arney; Olafsdottir, Katrin; Arnardóttir, Auður Arna (Stofnun stjórnsýslufræða og stjórnmála, Háskóli Íslands, 2011-12)
    Fyrirtæki og stofnanir þurfa að laga sig að breyttum aðstæðum þegar þjóðar - búskapurinn verður fyrir skyndilegu áfalli eins og raunin varð á Íslandi haustið 2008. Margt bendir til þess að skipulagsheildir beiti gjarnan uppsögnum ...
  • Kristjansson, Alfgeir L; Sigfusdottir, Inga Dora (BioMed Central, 2015-04-30)
    Electronic cigarette (EC) use is currently subject to a debate concerning safety, regulation need, and probable contribution to smoking cessation. An important gap in this debate is the lack of distinction between minors and adults. This is problematic ...
  • Torfason, Kristinn; Valfells, Agust; Manulesco, Andrei (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 ...
