      Donner, Lucas; Wiklund Gustin, Lena (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-13)
      Caring conversations are considered essential in psychiatric and mental health nursing. However, some patients are more or less silent and rarely express themselves verbally. This can be challenging for nurses who also need to find ways of communicating with these patients. Therefore, the aim of this study is to describe psychiatric nurses’ lived experiences of communication with patients who rarely ...
    • Concepts for structured illumination microscopy with extended axial resolution through mirrored illumination 

      Manton, James D.; Ströhl, Florian; Fiolka, Reto; Kaminski, Clemens F.; Rees, Eric J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-20)
      Wide-field fluorescence microscopy, while much faster than confocal microscopy, suffers from a lack of optical sectioning and poor axial resolution. 3D structured illumination microscopy (SIM) has been demonstrated to provide optical sectioning and to double the resolution limit both laterally and axially, but even with this the axial resolution is still worse than the lateral resolution of ...
    • 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)], ...

      Intraoperative tracking of laparoscopic instruments is often a prerequisite for computer and roboticassisted interventions. While numerous methods for detecting, segmenting and tracking of medical instruments based on endoscopic video images have been proposed in the literature, key limitations remain to be addressed: Firstly, robustness, that is, the reliable performance of state-of-the-art methods ...
    • RAT-RS: a reporting standard for improving the documentation of data use in agent-based modelling 

      Achter, Sebastian; Borit, Melania; Chattoe-Brown, Edmund; Siebers, Peer-Olaf (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-30)
      This article describes and justifies a reporting standard to improve data use documentation in Agent-Based Modelling. Following the development of reporting standards for models themselves, empirical modelling has now developed to the point where these standards need to take equally effective account of data use (which previously has tended to be an afterthought to model description). It is ...

      Sønvisen, Signe Annie; Thorvaldsen, Trine; Holmen, Ingunn Marie (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-18)
      Since the late 1980s, Norwegian fishers have been subjected to a cohesive regulatory regime aimed at sustainable resource management. Despite high occupational injury rates and exposure to several factors that may influence health negatively, regulation of occupational health and safety (OHS) came late in fishing compared with other industries. Fisheries management and safety management are not ...
    • Dust observations from Parker Solar Probe: Dust ejection from the inner Solar System 

      Mann, Ingrid; Czechowski, Andrzej (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-02)
      Context. The FIELDS instrument onboard Parker Solar Probe (PSP) observes dust impacts on the spacecraft. The derived dust flux rates suggest that the particles originate from the vicinities of the Sun and are ejected by radiation pressure. Radiation pressure typically ejects particles of several 100 nm and smaller, which are also affected by the electromagnetic force.<p> Aims. We aim to understand ...
