      Shu, Beibei; Sziebig, Gabor; Solvang, Bjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-11)
      Bin picking is a typical work, which is easy to automate up to a given complexity of the work-piece dimensions. In case of casted work-pieces, the dimensions are most of the time not accurate enough for an industrial robot to be able to pick it up without additional sensors/intelligence. In this paper we introduce a cyber-physical system, where all sensors, actuators, machines and industrial robot ...

    • Fractional integral-like processing in retinal cones reduces noise and improves adaptation 

      Martinecz, Antal; Niitsuma, Mihoko (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-04)
      In the human retina, rod and cone cells detect incoming light with a molecule called rhodopsin. After rhodopsin molecules are activated (by photon impact), these molecules activate the rest of the signalling process for a brief period of time until they are deactivated by a multistage process. First, active rhodopsin is phosphorylated multiple times. Following this, they are further inhibited by the ...

    • How can a binary switch within the pars tuberalis control seasonal timing of reproduction? 

      Wood, Shona Hiedi (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10)
      Life in seasonally changing environments is challenging. Biological systems have to not only respond directly to the environment, but also schedule life history events in anticipation of seasonal changes. The cellular and molecular basis of how these events are scheduled is unknown. Cellular decision-making processes in response to signals above certain thresholds regularly occur i.e. cellular fate ...
    • Managing Risk of Non-Communicable Diseases in Women with Bulimia Nervosa or Binge Eating Disorders: A Randomized Trial with 12 Months Follow-Up 

      Mathisen, Therese Fostervold; Sundgot-Borgen, Jorunn; Rosenvinge, Jan H; Bratland-Sanda, Solfrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-03)
      Persons with bulimia nervosa (BN) or binge eating disorder (BED) have an elevated risk of non-communicable diseases (NCDs). However, lowering this risk is rarely addressed in standard cognitive-behavioral treatment (CBT). We aimed to compare CBT with an intervention combining physical exercise and dietary therapy (PED-t), and hypothesized that the PED-t would do better than CBT in lowering the risk ...
