    The hybrid graphene - hexagonal boron nitride (G-hBN) systems offer new routes in the design of nanoscale electronic devices. Using ab initio density functional theory calculations we investigate the dynamics of zig-zag nanoribbons a few interatomic ...
  • Torfason, Kristinn; Valfells, Agust; Manolescu, Andrei (ArXiv, 2016-08)
    High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission from a prolate spheroidal tip. The space charge limited current is several times lower than the current calculated with ...

    This study examined the effects and specificity of structured and unstructured activities played at the playground Primo Sport 0246 in Northern Italy on motor skill competence in five years old children. The playground was specifically designed to ...
  • Song, Yiran; Cheng, Qingsha S.; Koziel, Slawomir (MDPI AG, 2019-07-09)
    In order to minimize the number of evaluations of high-fidelity (fine) model in the optimization process, to increase the optimization speed, and to improve optimal solution accuracy, a robust and computational-efficient multi-fidelity local surrogate-model ...
  • Budde, Henning; Wegner, Mirko; Soya, Hideaki; Voelcker-Rehage, Claudia; McMorris, Terry (Hindawi Limited, 2016)
    The human brain adapts to changing demands by altering its functional and structural properties (neuroplasticity) which results in learning and acquiring skills. Convergent evidence from both human and animal studies suggests that enhanced physical ...
  • Gargiulo, Paolo; Árnadóttir, Íris Dröfn; Gíslason, Magnús; Edmunds, Kyle; Ólafsson, Ingvar (Hindawi Limited, 2017)
    This paper illustrates the feasibility and utility of combining cranial anatomy and brain function on the same 3D-printed model, as evidenced by a neurosurgical planning case study of a 29-year-old female patient with a low-grade frontal-lobe glioma. ...

    Muscle degeneration has been consistently identified as an independent risk factor for high mortality in both aging populations and individuals suffering from neuromuscular pathology or injury. While there is much extant literature on its quantification ...
  • Reuter, Eva-Maria; Vieluf, Solveig; Koutsandreou, Flora; Hübner, Lena; Budde, Henning; Godde, Ben; Voelcker-Rehage, Claudia (Frontiers Media SA, 2019-01-28)
    The ability to selectively attend to task-relevant information increases throughout childhood and decreases in older age. Here, we intended to investigate these opposing developmental trajectories, to assess whether gains and losses early and late in ...

    Falls to the side are the leading cause of hip fractures in the elderly. The load that a person experiences during a fall cannot be measured with volunteers for ethical reasons. To evaluate injurious loads, while considering relevant energy input and ...
  • Bekasiewicz, Adrian; Koziel, Slawomir (Polish Academy of Sciences, 2016-12-01)
    In this paper, a novel structure of a compact UWB slot antenna and its design optimization procedure has been presented. In order to achieve a sufficient number of degrees of freedom necessary to obtain a considerable size reduction rate, the slot is ...
  • Koziel, Slawomir; Bekasiewicz, Adrian (Walter de Gruyter GmbH, 2016-12-13)
    Re-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various ...
  • Fleps, Ingmar; Enns-Bray, William S.; Guy, Pierre; Ferguson, Stephen J.; Cripton, Peter A.; Helgason, Benedikt (Public Library of Science (PLoS), 2018-11-26)
    The majority of hip fractures have been reported to occur as a result of a fall with impact to the greater trochanter of the femur. Recently, we developed a novel cadaveric pendulum-based hip impact model and tested two cadaveric femur-pelvis constructs, ...
  • Sigurðardóttir, Silja Rán (Háskólinn í Reykjavík, 2014-09-30)
    Low temperature geothermal resources provide hot water that is commonly used for space heating and various applications. A geothermal resource is considered to be a renewable energy source that can be utilized by current and future generations if ...
  • Abdullah, Nzar; Tang, Chi-Shung; Manolescu, Andrei; Gudmundsson, Vidar (Springer Science and Business Media LLC, 2019-10-11)
    Transport properties of a quantum dot coupled to a photon cavity are investigated using a quantum master equation in the steady-state regime. In the off-resonance regime, when the photon energy is smaller than the energy spacing between the lowest ...
