    • Lipid Levels During Adult Lifetime in Men and Women With and Without a Subsequent Incident Myocardial Infarction: A Longitudinal Analysis of Data From the Tromsø Study 1974 to 2016 

      Albrektsen, Grethe; Wilsgaard, Tom; Heuch, Ivar; Løchen, Maja-Lisa; Thelle, Dag Steinar; Njølstad, Inger; Grimsgaard, Sameline; Bønaa, Kaare Harald (Journal article; Peer reviewed, 2023)
      Background The atherosclerotic effect of an adverse lipid profile is assumed to accumulate throughout life, leading to increased risk of myocardial infarction (MI). Still, little is known about age at onset and duration ...

    • Liposomal doxorubicin improves radiotherapy response in hypoxic prostate cancer xenografts 

      Hagtvet, Eirik; Røe, Kathrine; Olsen, Dag R. (Peer reviewed; Journal article, 2011-10-07)
      Background: Tumor vasculature frequently fails to supply sufficient levels of oxygen to tumor tissue resulting in radioresistant hypoxic tumors. To improve therapeutic outcome radiotherapy (RT) may be combined with cytotoxic ...

    • Local Gaussian Cross-Spectrum Analysis 

      Jordanger, Lars Arne; Tjøstheim, Dag Bjarne (Journal article; Peer reviewed, 2023)
      The ordinary spectrum is restricted in its applications, since it is based on the second-order moments (auto- and cross-covariances). Alternative approaches to spectrum analysis have been investigated based on other measures ...

    • Local Lead–Lag Relationships and Nonlinear Granger Causality: An Empirical Analysis 

      Otneim, Håkon; Berentsen, Geir Drage; Tjøstheim, Dag Bjarne (Journal article; Peer reviewed, 2022)
      The Granger causality test is essential for detecting lead–lag relationships between time series. Traditionally, one uses a linear version of the test, essentially based on a linear time series regression, itself being ...

    • Local Likelihood 

      Otneim, Håkon (Master thesis, 2012-04-23)
      Methods for probability density estimation are traditionally classified as either parametric or non-parametric. Fitting a parametric model to observations is generally a good idea when we have sufficient information on the ...

    • A Local Streamline Eulerian-Lagrangian Method for Two-Phase Flow 

      Ask, A. K.; Dahle, Henrik K.; Karlsen, Kenneth Hvistendahl; Nordhaug, Hans Fredrik (Journal article, 2000)
      A method for solving the saturation equation for two-phase now is presented. The method may be viewed as an operator splitting method or as an Eulerian-Lagrangian backtracking procedure or as a modi£ed method of characteristics. ...

    • Log Hochschild Homology of Categorical Products and Coproducts 

      Vågset, Erlend Raa (Master thesis, 2017-07-26)
      As the front page implies, this is a thesis about log Hochschild homology. Our primary goal will be to understand how the log Hochschild homology groups acts on products and coproducts in the category of commutative pre-log ...

    • Logarithmic Hochschild homology 

      Piceghello, Stefano (Master thesis, 2015-06-01)
      The purpose of this thesis is to analyse the logarithmic Hochschild homology for pre-log rings and to provide some tools to compute it in certain cases. One of the main strategies that we will employ to describe the log ...

    • Logistrule: A knowledge-based system for logistic regression 

      Aarseth, Jan H.; Heuch, Ivar (Statistical report no. 28, Research report, 1996-07)

    • Long time well-posedness of Whitham-Boussinesq systems 

      Paulsen, Martin Oen (Journal article; Peer reviewed, 2022)
      Consideration is given to three different full dispersion Boussinesq systems arising as asymptotic models in the bi-directional propagation of weakly nonlinear surface waves in shallow water. We prove that, under a ...

    • Long Wave Models with Application to High Speed Vessels in Shallow Water 

      Torsvik, Tomas (Doctoral thesis, 2007-02-23)

    • Machine learning in marine ecology: an overview of techniques and applications 

      Rubbens, Peter; Brodie, Stephanie; Cordier, Tristan; Desto Barcellos, Diogo; DeVos, Paul; Fernandes-Salvador, Jose A; Fincham, Jennifer; Gomes, Alessandra; Handegard, Nils Olav; Howell, Kerry L.; Jamet, Cédric; Kartveit, Kyrre Heldal; Moustahfid, Hassan; Parcerisas, Clea; Politikos, Dimitris V.; Sauzède, Raphaëlle; Sokolova, Maria; Uusitalo, Laura; Van den Bulcke, Laure; van Helmond, Aloysius; Watson, Jordan T.; Welch, Heather; Beltran-Perez, Oscar; Chaffron, Samuel; Greenberg, David S.; Kühn, Bernhard; Kiko, Rainer; Lo, Madiop; Lopes, Rubens M.; Möller, Klas Ove; Michaels, William; Pala, Ahmet; Romagnan, Jean-Baptiste; Schuchert, Pia; Seydi, Vahid; Villasante, Sebastian; Malde, Ketil; Irisson, Jean-Olivier (Journal article; Peer reviewed, 2023)
      Machine learning covers a large set of algorithms that can be trained to identify patterns in data. Thanks to the increase in the amount of data and computing power available, it has become pervasive across scientific ...

    • Marginalized iterative ensemble smoothers for data assimilation 

      Stordal, Andreas Størksen; Lorentzen, Rolf Johan; Fossum, Kristian (Journal article; Peer reviewed, 2023)
      Data assimilation is an important tool in many geophysical applications. One of many key elements of data assimilation algorithms is the measurement error that determines the weighting of the data in the cost function to ...

    • Markovmodulerte Poisson-prosessar som modellar for dykketidsdata 

      Mossestad, Mona Christin (Master thesis, 2010-03-23)
      Alle pattedyr som lever i sjøen må opp til overlata for å puste, og det er når dyra bryt overflata at det er mogeleg for oss å observere dei. Det er ikkje alltid lett å oppdage dyra, og sannsynligheten for å oppdage eit ...
