      Hammer, Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-06)
      New ideas are constantly being produced as a changing world demands solutions to new problems. International environmental regimes often present ideas to reduce negative human effects on the environment. Implementation of ideas has often been studied through diffusion theory, where ideas are expected to be implemented in their original version. Translation theory from New Scandinavian Institutionalism ...
    • Almost every path structure is not variational 

      Kruglikov, Boris; Matveev, Vladimir S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-15)
      Given a smooth family of unparameterized curves such that through every point in every direction there passes exactly one curve, does there exist a Lagrangian with extremals being precisely this family? It is known that in dimension 2 the answer is positive. In dimension 3, it follows from the work of Douglas that the answer is, in general, negative. We generalise this result to all higher dimensions ...

      The Neogene–Quaternary development of the ∼700 km long mid-Norwegian and Lofoten–Vesterålen continental margin is reconstructed using a dense grid of 2D seismic data and exploration wellbores. Overall, widespread ocean current-controlled contourite drifts built up along the whole margin segment from the mid-Miocene onwards (c. 11 Ma, Kai Formation). The onset (c. 8.8 Ma) of a large inner shelf ...
    • Intersecting near-optimal spaces: European power systems with more resilience to weather variability 

      Grochowicz, Aleksander; van Greevenbroek, Koen; Benth, Fred Espen; Zeyringer, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-03)
      We suggest a new methodology for designing robust energy systems. For this, we investigate so-called near-optimal solutions to energy system optimisation models; solutions whose objective values deviate only marginally from the optimum. Using a refined method for obtaining explicit geometric descriptions of these near-optimal feasible spaces, we find designs that are as robust as possible to ...
    • Predicting Breast Cancer Leveraging Supervised Machine Learning Techniques 

      Aamir, Sanam; Rahim, Aqsa; Aamir, Zain; Abbasi, Saadullah Farooq; Khan, Muhammad Shahbaz; Alhaisoni, Majed; Khan, Muhammad Attique; Khan, Khyber; Ahmad, Jawad (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)
      Breast cancer is one of the leading causes of increasing deaths in women worldwide. The complex nature (microcalcification and masses) of breast cancer cells makes it quite difficult for radiologists to diagnose it properly. Subsequently, various computer-aided diagnosis (CAD) systems have previously been developed and are being used to aid radiologists in the diagnosis of cancer cells. However, due ...

      In recent years, the interest in cannabidiol (CBD) has increased because of the lack of psychoactive properties. However, CBD has low solubility and bioavailability, variable pharmacokinetics profiles, poor stability, and a pronounced presystemic metabolism. CBD nanoformulations include nanosuspensions, polymeric micelles and nanoparticles, hybrid nanoparticles jelled in cross-linked chitosan, and ...
    • A Computational Protocol for Vibrational Circular Dichroism Spectra of Cyclic Oligopeptides 

      Eikås, Karolina Solheimslid; Beerepoot, Maarten; Ruud, Kenneth (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-05)
      Cyclic peptides are a promising class of compounds for next-generation antibiotics as they may provide new ways of limiting antibiotic resistance development. Although their cyclic structure will introduce some rigidity, their conformational space is large and they usually have multiple chiral centers that give rise to a wide range of possible stereoisomers. Chiroptical spectroscopies such as ...
    • Effectiveness of LRB in Curved Bridge Isolation: A Numerical Study 

      Gupta, Praveen Kumar; Ghosh, Goutam; Kumar, Virendra; Paramasivam, Prabhu; Dhanasekaran, Seshathiri (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-07)
      Lead Rubber Bearings (LRBs) represent one of the most widely employed devices for the seismic protection of structures. However, the effectiveness of the same in the case of curved bridges has not been judged well because of the complexity involved in curved bridges, especially in controlling torsional moments. This study investigates the performance of an LRB-isolated horizontally curved ...
    • Supervised Classifications of Optical Water Types in Spanish Inland Waters 

      Pereira-Sandoval, Marcela; Ruescas, Ana Belen; García-Jimenez, Jorge; Blix, Katalin; Delegido, Jesús; Moreno, José (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-04)
      Remote sensing of lake water quality assumes there is no universal method or algorithm that can be applied in a general way on all inland waters, which usually have different in-water components affecting their optical properties. Depending on the place and time of year, the lake dynamics, and the particular components of the water, non-tailor-designed algorithms can lead to large errors or lags in ...
    • Spatial variability of nocturnal stability regimes in an operational weather prediction model 

      Kähnert, Marvin; Sodemann, Harald; Remes, Teresa Maaria; Fortelius, Carl; Bazile, Eric; Esau, Igor (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-15)
      Forecast errors in near-surface temperatures are a persistent issue for numerical weather prediction models. A prominent example is warm biases during cloud-free, snow-covered nights. Many studies attribute these biases to parametrized processes such as turbulence or radiation. Here, we focus on the contribution of physical processes to the nocturnal temperature development. We compare model timestep ...
