  The starburst galaxy NGC 253 revisited by H.E.S.S. and Fermi-LAT 

  Abdalla, H.; Arcaro, C.; Backes, M.; Barnard, M.; Böttcher, M.; Chandra, S.; Garrigoux, T.; Krüger, P.P.; Ndiyavala, H.; Seyffert, A.S.; Spanier, F.; Sushch, I.; Van der Walt, D.J.; Van Rensburg, C.; Venter, C.; Wadiasingh, Z.; Zacharias, M. (EDP Sciences, 2018)

  Context. NGC 253 is one of only two starburst galaxies found to emit γ-rays from hundreds of MeV to multi-TeV energies. Accurate measurements of the very-high-energy (VHE; E > 100 GeV) and high-energy (HE; E > 60 MeV) ...
• Sequence analysis of cell-free DNA derived from cultured human bone osteosarcoma (143B) cells 

  Bronkhorst, Abel Jacobus; Wentzel, Johannes F.; Peters, Dimetrie L.; Aucamp, Janine; Pretorius, Piet J. (Sage, 2018)

  The true importance of cell-free DNA in human biology, together with the potential scale of its clinical utility, is tarnished by a lack of understanding of its composition and origin. In investigating the cell-free DNA ...
• The development of a systems development methodology for location-based games 

  Barnard, Jacques; Huisman, Magda; Drevin, Günther R. (ACM, 2018)

  Currently, there is a lack of systems development methodologies (SDMs) suitable for the development of location-based games. This research introduced a newly developed SDM to aid in the development process of location-based ...
• Use of ion-assisted sputtering technique for producing photocatalytic titanium dioxide thin films: influence of thermal treatments on structural and activity properties based on the decomposition of stearic acid 

  Vishnyakov, V.; Kriek, R.J.; Kelly, P.J.; Humblot, J.; Allen, N.S. (Elsevier, 2018)

  Titanium dioxide thin films were deposited by the reactive ion-assisted sputtering method from titanium targets at various partial pressures and deposition parameters. The films were deposited onto substrates at temperatures ...
• Numerical integration of stochastic differential equations: a parallel cosmic ray modulation implementation on Africa’s fastest computer 

  Moloto, K.D.; Engelbrecht, N.E.; Strauss, R.D.; Van den Berg, J.P.; Moeketsi, D.M. (Elsevier, 2018)

  Three-dimensional studies of the transport and modulation of cosmic ray particles in turbulent astrospheres require large-scale simulations using specialized scientific codes. Essentially, a multi-dimensional Fokker-Planck ...
