Simulation of a suite of generic long-pulse neutron instruments to optimize the time structure of the European Spallation Source.

The Review of scientific instruments

Lefmann K, Klenø KH, Birk JO, Hansen BR, Holm SL, Knudsen E, Lieutenant K, von Moos L, Sales M, Willendrup PK, Andersen KH.
PMID: 23742588
Rev Sci Instrum. 2013 May;84(5):055106. doi: 10.1063/1.4803167.

We here describe the result of simulations of 15 generic neutron instruments for the long-pulsed European Spallation Source. All instruments have been simulated for 20 different settings of the source time structure, corresponding to pulse lengths between 1 ms...

Geophysics. Longitudinal variation in springtime ozone trends.

Nature

Knudsen BM, Andersen SB.
PMID: 11607021
Nature. 2001 Oct 18;413(6857):699-700. doi: 10.1038/35099677.

Satellite measurements indicate that mid-latitude ozone depletion in the Northern Hemisphere spring during 1979-97 was worst over Europe and Russia. Here we show that these longitudinal differences in ozone trends are due to a combination of decadal variations in...

Chronic fatigue syndrome in the media: a content analysis of newspaper articles.

JRSM short reports

Knudsen AK, Omenås AN, Harvey SB, Løvvik CM, Lervik LV, Mykletun A.
PMID: 21637403
JRSM Short Rep. 2011 May;2(5):42. doi: 10.1258/shorts.2011.011016. Epub 2011 May 25.

OBJECTIVES: Although cognitive behavioural therapy and graded exercise treatment are recognized evidence-based treatments for chronic fatigue syndrome/myalgic encephalomyelitis (ME), their use is still considered controversial by some patient groups. This debate has been reflected in the media, where many...

Steady-state two-phase flow in porous media: statistics and transport properties.

Physical review letters

Tallakstad KT, Knudsen HA, Ramstad T, Løvoll G, Måløy KJ, Toussaint R, Flekkøy EG.
PMID: 19257676
Phys Rev Lett. 2009 Feb 20;102(7):074502. doi: 10.1103/PhysRevLett.102.074502. Epub 2009 Feb 18.

We study experimentally the case of steady-state simultaneous two-phase flow in a quasi-two-dimensional porous media. The dynamics is dominated by the interplay between a viscous pressure field from the wetting fluid and bubble transport of a less viscous, nonwetting...

Thermal dissociation of molten KHSO4: temperature dependence of Raman spectra and thermodynamics.

The journal of physical chemistry. B

Knudsen CB, Kalampounias AG, Fehrmann R, Boghosian S.
PMID: 18767773
J Phys Chem B. 2008 Sep 25;112(38):11996-2000. doi: 10.1021/jp801853z. Epub 2008 Sep 03.

Raman spectroscopy is used to study the thermal dissociation of molten KHSO4 at temperatures of 240-450 degrees C under static equilibrium conditions. Raman spectra obtained at 10 different temperatures for the molten phase and for the vapors thereof exhibit...

Computer disease simulation models: integrating evidence for health policy.

Academic radiology

Rutter CM, Knudsen AB, Pandharipande PV.
PMID: 21435924
Acad Radiol. 2011 Sep;18(9):1077-86. doi: 10.1016/j.acra.2011.02.004. Epub 2011 Mar 23.

Computer disease simulation models are increasingly being used to evaluate and inform health care decisions across medical disciplines. The aim of researchers who develop these models is to integrate and synthesize short-term outcomes and results from multiple sources to...

An eEF1A1 truncation encoded by PTI-1 exerts its oncogenic effect inside the nucleus.

Cancer cell international

Dahl LD, Corydon TJ, Ränkel L, Nielsen KM, Füchtbauer EM, Knudsen CR.
PMID: 24571548
Cancer Cell Int. 2014 Feb 26;14(1):17. doi: 10.1186/1475-2867-14-17.

BACKGROUND: The oncogene PTI-1 was originally isolated from a prostate cancer cell line by its capability to transform rat fibroblasts. The PTI-1 mRNA has a very eccentric structure as the 5'UTR is similar to prokaryotic 23S rRNA, while the...

Cardiac Microvascular Dysfunction in Women Living With HIV Is Associated With Cytomegalovirus Immunoglobulin G.

Open forum infectious diseases

Knudsen A, Thorsteinsson K, Christensen TE, Hasbak P, Ripa RS, Panum I, Lebech AM, Kjaer A.
PMID: 30214912
Open Forum Infect Dis. 2018 Sep 11;5(9):ofy205. doi: 10.1093/ofid/ofy205. eCollection 2018 Sep.

BACKGROUND: People living with HIV (PLWH) appear to be at increased risk of cardiovascular disease (CVD), and this is possibly more pronounced in women living with HIV (WLWH). In the general population, men are more likely to develop obstructive...

Functional Ultrasound Imaging of Spinal Cord Hemodynamic Responses to Epidural Electrical Stimulation: A Feasibility Study.
