  • Symmetries on self-similar fractals 
    Mentzoni, Mauritz Angell (Master thesis / Masteroppgave, 2023)
    This thesis discusses self-similar fractals, more specifically different symmetries on self-similar fractals. We build the fractal space as a collection of compact subsets of a complete metric space. Further, we add IFS ...
  • Symmetry in a space of conceptual variables 
    Helland, Inge Svein (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    A conceptual variable is any variable defined by a person or by a group of persons. Such variables may be inaccessible, meaning that they cannot be measured with arbitrary accuracy on the physical system under consideration ...
  • A symmetry-condition for quasi-symmetric domains 
    Zelow, R. (Research report / Forskningsrapport, 1980)
  • Symplectic birational transformations of finite order on O'Grady's sixfolds 
    Grossi, Annalisa; Onorati, Claudio; Veniani, Davide Cesare (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    We prove that any symplectic automorphism of finite order on a manifold of type OG6 acts trivially on the Beauville–Bogomolov–Fujiki lattice and that any birational transformation of finite order acts trivially on its ...
  • Syndecan-4 is essential for development of concentric myocardial hypertrophy via stretch-induced activation of the calcineurin-NFAT pathway 
    Finsen, Alexandra; Lunde, Ida Gjervold; Sjaastad, Ivar; Østli, Even K.; Lyngra, Marianne; Jarstadmarken, Hilde; Hasic, Almira; Nygård, Ståle; Wilcox-Adelman, Sarah A; Goetinck, Paul F; Lyberg, Torstein; Skrbic, Biljana; Florholmen, Geir; Tønnessen, Theis; Louch, William Edward; Djurovic, Srdjan; Carlson, Cathrine Rein; Christensen, Geir Arve (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2011)
    Sustained pressure overload leads to compensatory myocardial hypertrophy and subsequent heart failure, a leading cause of morbidity and mortality. Further unraveling of the cellular processes involved is essential for ...
  • Synspunkter på tidsrekkeanalyser 
    Sverdrup, Erling (Research report / Forskningsrapport, 1980)
  • Synthetic CDOs - An introduction, evaluation and risk estimation 
    Korsnes, Stig (Master thesis / Masteroppgave, 2008)
    In the last decade we have seen a tremendous growth in the issuance of derivatives linked to the credit risk of an individual, or a pool of obligors. While some have been around for a while, some are relatively new. One ...
  • System optimum vs. user equilibrium in static and dynamic traffic routing 
    Venstad, Jon Marius (Master thesis / Masteroppgave, 2008)
    This thesis treats traffic as flow in static and dynamic networks. This may be any kind of traffic; cars, information etc. Two flows are of particular interest: The system optimum, which minimizes total travel time for all ...
  • System reliability evaluation using conditional Monte Carlo methods 
    Huseby, Arne Bang; Naustdal, Morten; Vårli, Ingeborg Drengstig (Research report / Forskningsrapport, 2004)
    The paper shows how Monte Carlo methods can be improved significantly by conditioning on a suitable variable or vector. In particular this principle is applied to system reliability evaluation. Different choices of variables ...
  • Systems and Lattices 
    Aubert, Karl Egil (Research report / Forskningsrapport, 1972)
  • SYZYGIES OF ABELIAN AND BIELLIPTIC SURFACES IN ℙ⁴ 
    Aure, Alf; Decker, Wolfram; Hulek, Klaus; Popescu, Sorin; Ranestad, Kristian (Research report / Forskningsrapport, 1996)
  • Tailored Graphical Lasso for Data Integration in Gene Network Reconstruction 
    Lingjærde, Camilla (Master thesis / Masteroppgave, 2019)
    Conventional differential gene expression analysis by methods such as SAM (Chu et al., 2001), student’s t-test and Empirical Bayes (Efron et al., 2001) often searches for statistically significant genes without considering ...
  • Tailored graphical lasso for data integration in gene network reconstruction 
    Lingjærde, Camilla; Lien, Tonje G.; Borgan, Ørnulf; Bergholtz, Helga; Glad, Ingrid K. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Background Identifying gene interactions is a topic of great importance in genomics, and approaches based on network models provide a powerful tool for studying these. Assuming a Gaussian graphical model, ...
  • Take a look at the wild side 
    Ulfsby, Tale Bakken (Master thesis / Masteroppgave, 2018)
    The recent results on non-uniqueness of the Euler equations, all based on the theory developed in the papers by Camillo De Lellis and László Székelyhidi Jr., are believed to be connected to the theory of turbulent fluid ...
  • Tangent Structure of Non-Commutative Rings 
    Patrono, Richard Pedersen (Master thesis / Masteroppgave, 2020)
  • Tchebycheffian B-Splines Revisited: An Introductory Exposition 
    Lyche, Tom; Manni, Carla; Speleers, Hendrik (Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2019)
    Tchebycheffian splines are smooth piecewise functions where the different pieces are drawn from extended Tchebycheff spaces. They are a natural generalization of polynomial splines and can be represented in terms of an ...
  • Tchebycheffian spline spaces over planar T-meshes: Dimension bounds and dimension instabilities 
    Bracco, Cesare; Lyche, Tom; Manni, Carla; Speleers, Hendrik (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    We consider Tchebycheffian spline spaces over planar T-meshes and we study their dimension. We show that the structure of extended Tchebycheff spaces allows us to fully generalize the dimension upper bounds known in the ...
  • Ten modifiers of BRCA1 penetrance validated in a Norwegian series 
    Heramb, Cecilie; Ekstrøm, Per O; Tharmaratnam, Kukatharmini; Hovig, Eivind; Møller, Pål; Mæhle, Lovise (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Background Common genetic variants have been shown to modify BRCA1 penetrance. The aim of this study was to validate these reports in a special cohort of Norwegian BRCA1 mutation carriers that were selected ...
  • TENSOR PRODUCT FACTORIZATION AND MULTIPLIERS 
    Larsen, Ronald (Research report / Forskningsrapport, 1974)
  • A tensor product matrix approximation problem in quantum physics 
    Dahl, Geir; Leinaas, Jon Magne; Myrheim, Jan; Ovrum, Eirik (Research report / Forskningsrapport, 2006)
    We consider a matrix approximation problem arising in the study of entanglement in quantum physics. This notion represents a certain type of correlations between subsystems in a composite quantum system. The states of a ...
