  • Owen-Smith, N.; Martin, J. (Public Library of Science, 2015-06)
    An intermediate spatiotemporal scale of food procurement by large herbivores is evident within annual or seasonal home ranges. It takes the form of settlement periods spanning several days or weeks during which foraging ...
  • Khusal, R.; Da Costa Dias, B; Moodley, K.; Penny, C.; Reusch, U.; Knackmuss, S.; Little, M.; Weiss, S.F.T. (Public Library of Science, 2013-03-12)
    The 37kDa/67kDa laminin receptor (LRP/LR) is a central receptor mediating interactions between tumour cells and the basement membrane and is thereby a key player in adhesion and invasion, essential processes in metastatic ...
  • Cardoso, Gabriel Lopes; Ciraficia, Michele; Nampurib, Suresh (Springer, 2014-10-03)
    In this note, we employ indefinite theta functions to regularize canonical partition functions for single-center dyonic BPS black holes. These partition functions count dyonic degeneracies in the Hilbert space of ...
  • De Mello Koch, R.; Van Zyl, H.J.R. (Elsevier, 2017-05)
    We study the worldsheet S-matrix of a string attached to a D-brane in AdS5×S5. The D-brane is either a giant graviton or a dual giant graviton. In the gauge theory, the operators we consider belong to the su(2|3)sector of ...
  • Sokol, Janusz; Ibrahim, Rabha W.; Ahmad, M. Z; Al-Janaby, Hiba F. (DE GRUYTER OPEN LTD, BOGUMILA ZUGA 32A ST, 01-811 WARSAW, POLAND, 2015)
    Let SH be the class of functions f = h + (g) over bar that are harmonic univalent and sense-preserving in the open unit disk U = {z : vertical bar z vertical bar < 1} for which f(0) = f'(0) - 1 = 0. In this paper, we ...
  • Nabarro, F.R.N. (Physical Society, 1940)
    An estimate is given of the way in which the strain energy associated with a particle of precipitate depends upon the shape of the particle. It is shown that the energy can only be reduced if the precipitate forms in flat ...
  • Zhou, Y.; Chan, C.K.; Wong, K.H.; Lee, Y.C.E. (Hindawi Publishing Corporation, 2015-10-26)
    Recently, the first oligopolistic competition model of the closed-loop supply chain network involving uncertain demand and return has been established. This model belongs to the context of oligopolistic firms that compete ...
  • de Mello Koch, R.; Ramgoolam, S. (Springer Verlag, 2016-03)
    In a recent paper we showed that the correlators of free scalar field theory in four dimensions can be constructed from a two dimensional topological field theory based on so(4, 2) equivariant maps (intertwiners). The free ...
  • Hunt, Tamsin (2013-07-01)
    For many years stone-walled structures have been classified into different groups using aerial photography. The development of technology such as Google Earth and Geographic Information Systems has resulted in an increase ...

  • Naidoo, K.; Malindisa, S.T.; Otgaar, T.C.; Da Costa Dias, B.; Ferreirra, E.; Reusch, U.; Knackmuss, S.; Little, M.; Weiss, S.F.T.; Letsolo, B.T. (Public Library of Science., 2015-11-06)
    Cancer has become a major problem worldwide due to its increasing incidence and mortality rates. Both the 37kDa/67kDa laminin receptor (LRP/LR) and telomerase are overexpressed in cancer cells. LRP/LR enhances the invasiveness ...
  • Khumalo, T.; Ferreira, E.; Jovanovic, K.; Veale, R.B.; Weiss, S.F.T. (2015-10-01)
    Cancer is a global burden due to high incidence and mortality rates and is ranked the second most diagnosed disease amongst non-communicable diseases in South Africa. A high expression level of the 37kDa/67kDa laminin ...
  • Coetzer, K.L.; Erasmus, B.F.N.; Witkowski, E.T.F.; Bachoo, A.K. (Academy of Science of South Africa (ASSAf), 2010-07)
    This paper is a first step towards a conservation plan for the Kruger to Canyons Biosphere Reserve K2C) on the South African Central Lowveld, quantifying the historical land-cover trends 1993-2006). During the analysis ...
  • Abdalgabar, Ammar; Cornell, Alan S.; Deandrea, Aldo; McGarrie, Moritz (Springer, 2014-07-31)
    Even if the unification and supersymmetry breaking scales are around 106 to 109 TeV, a large A t coupling may be entirely generated at low energies through RGE evolution in the 5D MSSM. Independent of the precise details ...
  • Athenodorou, A.; Bennett, E.; Bergner, G.; Elander, D.; Lin, C.-J.D.; Lucini, B.; Piai, M. (Springer Verlag, 2016-06)
    Besides the Higgs particle discovered in 2012, with mass 125 GeV, recent LHC data show tentative signals for new resonances in diboson as well as diphoton searches at high center-of-mass energies (2 TeV and 750 GeV, ...
  • Nabarro, F.R.N. (Institute of Metals, 1947-10)
    Four recent papers by Laszlo on "Tessellated Stresses, Parts I-IV" published in the Journal of the Iron and Steel Institute, are reviewed in detail. The present review contains no new results.
  • Grover, B.P.C.; Johnson, R.H.; Tutu, H. (South African Water Research Commission, 2016-01)
    Mine leachates from gold tailings impoundments usually contain elevated concentrations of metals and sulphates that impact negatively on water quality. This study was aimed at assessing the leachability of such metals from ...
  • Brummer, Felix; McGarrie, Moritz; Weiler, Andreas (Springer, 2014-04-10)
    We study models of gauge-mediated supersymmetry breaking with a gauged horizontal SU(3)F symmetry acting on the quark superfields. If SU(3)F is broken nonsupersymmetrically by F -term vacuum expectation values, the massive ...
  • de Mello Koch, R.; Mathwin, C.; Van Zyl, H.J.R. (Springer Verlag, 2016-03)
    We consider excitations of LLM geometries described by coloring the LLM plane with concentric black rings. Certain closed string excitations are localized at the edges of these rings. The string theory predictions for the ...

    This paper considers two replacement policies for systems which, during their useful life, are subject to deterioration. Strategy 1: after a failure, the repair cost is estimated. If the repair cost exceeds a given limit, ...
