Systematic variation in observing altitude of enhanced ion line by the pump near fifth gyroharmonic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-20)The observation of ultra high frequency radar during an ionospheric experiment carrying out at the European Incoherent Scatter Scientific Association, demonstrates a systematic variation in the altitude of the pump enhanced ion line, which is quite remarkably dependent on the pump frequency, that is, when the pump frequency sweeps above the fifth gyroharmonic, the altitude of the enhanced ion line ... -
Novel Scaffolds for Dual Specificity Tyrosine-Phosphorylation-Regulated Kinase (DYRK1A) Inhibitors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-10)DYRK1A is one of five members of the dual-specificity tyrosine (Y) phosphorylation-regulated kinase (DYRK) family. The DYRK1A gene is located in the Down syndrome critical region and regulates cellular processes related to proliferation and differentiation of neuronal progenitor cells during early development. This has focused research on its role in neuronal degenerative diseases, including ... -

Evaluation of the Weather Research and Forecasting (WRF) model with respect to wind in complex terrain
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018)In this study the performance of the Weather Research and Forecast (WRF) model in a complex and coastal terrain has been evaluated with focus on wind resource assessment. The study area is a small community on the northern part of the island Senja, Norway. The community, with fishery and seafood as its main industry, is being limited by poor grid connection. One of the solutions is to increase ... -

Menopausal hormone therapy and breast cancer risk: effect modification by body mass through life
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-06)It is not known whether increased breast cancer risk caused by menopausal hormone therapy (HT) depends on body mass patterns through life. In a prospective study of 483,241 Norwegian women aged 50–69 years at baseline, 7656 women developed breast cancer during follow-up (2006–2013). We combined baseline information on recalled body mass in childhood/adolescence and current (baseline) body mass index ... -
Granulocyte and monocyte CD11b expression during plasma separation is dependent on complement factor 5 (C5) – an ex vivo study with blood from a C5-deficient individual
(Journal article; Tidsskriftartikkel, 2018)The aim of the study was to investigate the role of complement factor 5 (C5) in reactions elicited by plasma separation using blood from a C5‐deficient (C5D) individual, comparing it to C5‐deficient blood reconstituted with C5 (C5DR) and blood from healthy donors. Blood was circulated through an <i>ex vivo</i> plasma separation model. Leukocyte CD11b expression and leukocyte–platelet conjugates were ... -
Bone trait ranking in the population is not established during antenatal growth but is robustly established in the first postnatal year
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-17)Efforts to understand the pathophysiology of bone fragility must focus on bone traits during growth. We hypothesized that variance in individual trait ranking in the population distribution is established by genetic factors and is reflected in foetal trait ranking in early pregnancy, but intrauterine factors modify trait ranking in late pregnancy, followed by the reinstating of this ranking during ... -

Pointwise estimates for heat kernels of convolution-type operators
(Journal article; Peer reviewed; Tidsskriftartikkel, 2018-04-16)We study the large‐time behaviour of the fundamental solution of parabolic equations with an elliptic part being non‐local convolution‐type operator. We assume that this operator is a generator of a Markov jump process, and that its convolution kernel decays at least exponentially at infinity. The fundamental solution shows rather different asymptotic behaviour depending on whether | x | ≲ t , or t ... -

Various social media platforms have recently emerged, providing free and simple science communication tools to reach the public and young people ... -
The asymmetric geospace as displayed during the geomagnetic storm on 17 August 2001
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-29)Previous studies have shown that conjugate auroral features are displaced in the two hemispheres when the interplanetary magnetic field (IMF) has a transverse (<i><sub>Y</sub></i>) component. It has also been shown that a <i>B<sub>Y</sub></i> component is induced in the closed magnetosphere due to the asymmetric loading of magnetic flux in the lobes following asymmetric dayside reconnection when the ... -
Electron Energy Spectrum and Auroral Power Estimation From Incoherent Scatter Radar Measurements
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-23)Differential energy flux of electrons precipitating into the high‐latitude ionosphere can be estimated from incoherent scatter radar observations of the ionospheric electron density profile. We present a method called ELSPEC for electron spectrum estimation from incoherent scatter radar measurements, which is based on integration of the electron continuity equation and spectrum model selection by ...
