      Fosse, Thomas Hol; Buch, Robert; Säfvenbom, Reidar; Martinussen, Monica (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-23)
      In order to optimize recruitment and the overall outcome of educational programmes, it is crucial to understand personal determinants of achievement. While several cognitive abilities and skills individually predict performance in academic and professional settings, it is less clear how personality translates into performance. This study addresses the impact of the Big Five personality trait, ...

    • Wavelet-based analogous phase scintillation index for high latitudes 

      Ahmed, Abu Baker E.; Tiwari, Rajesh N.; Strangeways, Hal J.; Dlay, Satnam Singh; Johnsen, Magnar Gullikstad (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-14)
      The Global Positioning System (GPS) performance at high latitudes can be severely affected by the ionospheric scintillation due to the presence of small-scale time-varying electron density irregularities. In this paper, an improved analogous phase scintillation index derived using the wavelet-transform-based filtering technique is presented to represent the effects of scintillation regionally at ...

    • A quantitative model for heat pulse propagation across large helical device plasmas 

      Zhu, Hao; Dendy, Richard O.; Chapman, Sandra; Inagaki, Shigeru (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-26)
      It is known that rapid edge cooling of magnetically confined plasmas can trigger heat pulses that propagate rapidly inward. These can result in large excursion, either positive or negative, in the electron temperature at the core. A set of particularly detailed measurements was obtained in Large Helical Device (LHD) plasmas [S. Inagaki et al., Plasma Phys. Controlled Fusion 52, 075002 (2010)], ...

    • Validation of the Graded Prognostic Assessment for Melanoma Using Molecular Markers (Melanoma-molGPA). 

      Nieder, Carsten; Hintz, Mandy; Bilger, Angelika; Oehlke, Oliver; Grosu, Anca L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03)
      Background: It has been suggested to replace the diagnosis-specific graded prognostic assessment (DS-GPA, based on performance status and number of brain metastases) for patients with primary malignant melanoma with the new Melanoma-molGPA. The latter is a more complex assessment, which also includes BRAF mutation status, age and extracranial metastases. To test the performance of the Melanoma-molGPA, ...

      Hermansen, Nina; Olsen, Kjell Ole Kjærland (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-20)
      We analyze how the implementation of the Norwegian policy on the Sámi language in school has shaped some Norwegian-speaking Sámi youths’ experiences and challenges of language learning. The research was conducted in Alta, Finnmark county. The youths interviewed in this study have had education in the Sámi language for the larger part, or for the entirety, of their primary and secondary education. ...

    • Zonal Wave Number Diagnosis of Rossby Wave-Like Oscillations Using Paired Ground-Based Radars 

      He, Maosheng; Yamazaki, Yosuke; Hoffmann, Peter; Hall, Chris; Tsutsumi, Masaki; Li, Guozhu; Chau, Jorge L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-03)
      Free traveling Rossby wave normal modes (RNMs) are often investigated through large-scale space-time spectral analyses, which therefore is subject to observational availability, especially in the mesosphere. Ground-based mesospheric observations were broadly used to identify RNMs mostly according to the periods of RNMs without resolving their horizontal scales. The current study diagnoses zonal ...

    • Some new (Hp,Lp) type inequalitiesof maximal operators of Vilenkin-Nörlund means with non-decreasing coefficients 

      Persson, Lars Erik; Tephanadze, G; Wall, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12)
      In this paper we prove and discuss some new (H<sub>p</sub>,L<sub>p</sub>) type inequalities of maximal operators of Vilenkin-Nörlund means with non-decreasing coefficients. We also apply these inequalities to prove strong convergence theorems of such Vilenkin-N ¨orlund means. These inequalities are the best possible in a special sense. As applications, both some well-known and new results are pointed out.

    • Fysisk aktivitet, risikofaktorer for hjerte- og karsykdommer og risiko for tidlig død blant samer og nordmenn i Finnmark 

      Hermansen, Rune Hermann; Jacobsen, Bjarne K. (Chapter; Bokkapittel, 2022-03-16)
      Hjerte- og karsykdommer er en av hovedårsakene til for tidlig død. Fokus på forebyggende tiltak er derfor viktig. Fysisk aktivitet er et gunstig forebyggende tiltak, men det er mangelfull kunnskap om sammenhengen mellom fysisk aktivitet, risikofaktorer for hjerte-og karsykdom og død hos urfolk, som eksempelvis samer. Historisk har den fleretniske befolkningen i nord hatt høyere hjerte- og kardødelighet ...

      Introduction: The relationship between circulating prolactin and invasive breast cancer has been investigated previously, but the association between prolactin levels and in situ breast cancer risk has received less attention.<p> <p>Methods: We analysed the relationship between pre-diagnostic prolactin levels and the risk of in situ breast cancer overall, and by menopausal status and use of ...

    • Designing a Service for Compliant Sharing of Sensitive Research Data 

      Sharma, Aakash; Bye Nilsen, Thomas; Johansen, Sivert; Johansen, Dag; Johansen, Håvard D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-09)
      Data-driven research is increasingly becoming fueled by access to open datasets, often shared publicly on the Internet. However, many research projects study sensitive data. They cannot easily participate in this shift as access to their data is significantly controlled by ethical and regulatory constraints. This paper discusses the requirements for building a service that enables sensitive data for ...

    • The oncolytic peptide LTX-315 kills cancer cells through Bax/Bak-regulated mitochondrial membrane permeabilization 

      Zhou, Heng; Forveille, Sabrina; Sauvat, Allan; Sica, Valentina; Izzo, Valentina; Durand, Sylvère; Müller, Kevin; Liu, Peng; Zitvogel, Laurence; Rekdal, Øystein; Kepp, Oliver; Kroemer, Guido (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-10)
      LTX-315 has been developed as an amphipathic cationic peptide that kills cancer cells. Here, we investigated the putative involvement of mitochondria in the cytotoxic action of LTX-315. Subcellular fractionation of LTX-315-treated cells, followed by mass spectrometric quantification, revealed that the agent was enriched in mitochondria. LTX-315 caused an immediate arrest of mitochondrial ...

    • Protein kinase A opposes the phosphorylation-dependent recruitment of glycogen synthase kinase 3β to A-kinase Anchoring Protein 220 

      Whiting, Jennifer L.; Nygren, Patrick J.; Tunquist, Brian J.; Langeberg, Lorene K.; Seternes, Ole Morten; Scott, John D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-18)
      The proximity of an enzyme to its substrate can influence rate and magnitude of catalysis. A-kinase anchoring protein 220 (AKAP220) is a multivalent anchoring protein that can sequester a variety of signal transduction enzymes. These include protein kinase A (PKA) and glycogen synthase kinase 3 (GSK3). Using a combination of molecular and cellular approaches we show that GSK3 phosphorylation of ...

    • Kunstnerisk utviklingsarbeid og satelittvirksomhet 

      Torell, Lisa; Edvine, Larssen (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      Kan man ane en viss risiko idet kunstutdanningsinstitusjonene nå overtar ansvaret individuelt for det arbeidet det nasjonale og tverrkunstneriske stipendiatprogrammet for kunstnerisk utviklingsarbeid (PKU), har utført? spør Edvine Larssen og Lisa Torell.
