3D image guided adaptive brachytherapy in patients with locally advanced cervical cancer: experience and clinical results from a minimum of six years of follow-up
(Peer reviewed; Journal article, 2021)In 2005, individualized 3D image guided brachytherapy was implemented for cervical cancer patients, in accordance with the (GYN) GEC ESTRO recommendation, at St. Olav's Hospital, Trondheim, Norway. This study reports the ... -
3D Maps of Mineral Composition and Hydroxyapatite Orientation in Fossil Bone Samples Obtained by X-ray Diffraction Computed Tomography
(Journal article; Peer reviewed, 2018)Whether hydroxyapatite (HA) orientation in fossilised bone samples can be non-destructively retrieved and used to determine the arrangement of the bone matrix and the location of muscle attachments (entheses), is a question ... -
3HSP J095507.9+355101: A flaring extreme blazar coincident in space and time with IceCube-200107A
(Peer reviewed; Journal article, 2020)The uncertainty region of the highly energetic neutrino IceCube200107A includes 3HSP J095507.9+355101 (z = 0.557), an extreme blazar, which was detected in a high, very hard, and variable X-ray state shortly after the ... -
The 3rd ESTRO-EFOMP core curriculum for medical physics experts in radiotherapy
(Peer reviewed; Journal article, 2022)Purpose To update the 2011 ESTRO-EFOMP core curriculum (CC) for education and training of medical physics experts (MPE)s working in radiotherapy (RT), in line with recent EU guidelines, and to provide a framework for ... -
6.8 W all-fiber supercontinuum source at 1.9-2.5 um
(Journal article; Peer reviewed, 2014)We report a simple method of generating a spectrally flat and high average power spectral density (up to 14 mW/nm) optical supercontinuum in the 1.95–2.5 μm range covering a transparency window of the atmosphere. The ... -
A consistent reduction of the two-layer shallow-water equations to an accurate one-layer spreading model
(Journal article; Peer reviewed, 2019)The gravity-driven spreading of one fluid in contact with another fluid is of key importance to a range of topics. These phenomena are commonly described by the two-layer shallow-water equations (SWE). When one layer is ... -
A correlative spatiotemporal microscale study of calcium phosphate formation and transformation within an alginate hydrogel matrix.
(Journal article; Peer reviewed, 2016)The modification of soft hydrogels with hard inorganic components is a method used to form composite materials with application in non-load-bearing bone tissue engineering. The inclusion of an inorganic component may provide ... -
