      The increasing use of pharmaceutical medications has significantly negative repercussions on the environment and human health. Here, a hydrothermal technique was employed to generate a single-crystalline molybdenum trioxide (MoO3)/functionalized multi-walled carbon nanotubes (MoO3/f-MWCNTs) nanocomposite that was then used as a novel electrode material for the electrochemical detection of phenothiazine ...
    • Rational design of Nd<inf>2</inf>O<inf>3</inf> decorated functionalized carbon nanofiber composite for selective electrochemical detection of carbendazim fungicides in vegetables, water, and soil samples 

      Palanisamy, Selvakumar; Alagumalai, Krishnapandi; Chiesa, Matteo; Kim, Seong-Cheol (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-22)
      Abuse of carbendazim (CBZ) leaves excessive pesticide residues on agricultural products, which endangers human health because of the residues' high concentrations. Hence, a composite consisting of functionalized carbon nanofibers (f-CNF) with neodymium oxide (Nd2O3) was fabricated to monitor CBZ at trace levels. The Nd2O3/f-CNF composite-modified electrode displays higher electro-oxidation ability ...

    • Transferability of graph neural networks: An extended graphon approach 

      Maskey, Sohir; Levie, Ron; Kutyniok, Gitta Astrid Hildegard (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-28)
      We study spectral graph convolutional neural networks (GCNNs), where filters are defined as continuous functions of the graph shift operator (GSO) through functional calculus. A spectral GCNN is not tailored to one specific graph and can be transferred between different graphs. It is hence important to study the GCNN transferability: the capacity of the network to have approximately the same ...
    • Real-Time Outdoor Localization Using Radio Maps: A Deep Learning Approach 

      Yapar, Cagkan; Levie, Ron; Kutyniok, Gitta Astrid Hildegard; Caire, Giuseppe (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-10)
      Global Navigation Satellite Systems typically perform poorly in urban environments, where the likelihood of line-of-sight conditions between devices and satellites is low. Therefore, alternative location methods are required to achieve good accuracy. We present LocUNet: A convolutional, end-to-end trained neural network (NN) for the localization task, which is able to estimate the position of a user ...

Maintaining the integrity of these standardized codes is important both for the functioning of health systems and for ensuring data used ...
    • New insights from an eight-year study on per- and polyfluoroalkyl substances in an urban terrestrial ecosystem 

      Heimstad, Eldbjørg Sofie; Nygård, Torgeir; Moe, Børge; Herzke, Dorte (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-06)
      Per- and polyfluoroalkyl substances (PFAS) were analysed in a high number of terrestrial samples of soil, earthworm, bird eggs and liver from red fox and brown rat in an urban area in Norway from 2013 to 2020. PFOS and the long chain PFCAs were the most dominating compounds in all samples, proving their ubiquitous distribution. Other less studied compounds such as 6:2 FTS were first and foremost ...

    • Ofret Nansen vitenskapen for freden? 

      Jølle, Harald Dag (Chapter; Bokkapittel, 2023)
      Da Fridtjof Nansen døde i 1930, skrev Nordahl Grieg hjem til sin bror Harald Grieg: «For et eventyrlig liv som er forbi, det var jo ikke én stor mand som døde, det var ti». Nansens brede virke, hans mange evner, hans tilstedeværelse i store hendelser gir alt et voldsomt inntrykk – og har gitt ham mange merkelapper: vitenskapsmann, polfarer, kunstner, diplomat, filantrop, for å nevne noen. <p> <p>Det ...

    • Advances in the expression and purification of human PARP1: A user-friendly protocol 

      Conceição, Carlota J.F.; Salgueiro, Bruno A.; Ribeiro, Paulo A.; Raposo, Maria; Moe, Elin (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-05)
      The PARP1 (Poly (ADP-ribose) polymerase 1) enzyme is essential for single and double-strand break repair in humans. Alterations affecting PARP1 activity have severe consequences for human health and are associated with pathologies like cancer, and metabolic and neurodegenerative disorders. Here, we have developed a fast and easy procedure for the expression and purification of PARP1. Biologically ...

    • DFT benchmarking for adsorption energy in wastewater treatment 

      Malloum, Alhadji; Conradie, Jeanet (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-31)
      Despite its potential importance, the computational chemistry of adsorption processes for wastewater treatment has received negligible attention. Exploring the literature shows several limitations in applying quantum chemistry to study adsorption processes in wastewater treatment. The choice of suitable functionals of density functional theory (DFT) is one of the critical limits of the current ...

      We present an implementation of a damped response framework for calculating resonant inelastic X-ray scattering (RIXS) at the equation-of-motion coupled-cluster singles and doubles (CCSD) and second-order approximate coupled-cluster singles and doubles (CC2) levels of theory in the open-source program eT. This framework lays the foundation for future extension to higher excitation methods (notably, ...
    • Exploring Earthly relations through curiography 

      Valtonen, Anu; Salmela, Tarja (Chapter; Bokkapittel, 2023-01-24)
      Recognizing that humans inhabit Earth with multiple others and that humans have worsened opportunities for life on Earth calls for a reassessment of the research practices through which the world is explored. The development of more-than-human methodologies is underway, as reflected in the emergence of more-than-human or multispecies ethnographies. However, leaning on ethnography as a methodological ...
    • Arctic HARE: A Machine Learning-Based System for Performance Analysis of Cross-Country Skiers
