  • Britz, Thomas; Cavenagh, Nicholas J.; Sørensen, Henrik Kragh (Electronic Journal of Combinatorics, 2015)
    We prove that each maximal partial Latin cube must have more than 29.289% of its cells filled and show by construction that this is a nearly tight bound. We also prove upper and lower bounds on the number of cells containing ...
  • Jackson, Marcel; Stokes, Tim E. (Elsevier, 2015)
    We study the algebraic theory of computable functions, which can be viewed as arising from possibly non-halting computer programs or algorithms, acting on some state space, equipped with operations of composition, if-then-else ...
  • Jung, Yoonsuh; Hu, Jianhua (Taylor and Francis, 2015)
    Cross-validation (CV) type of methods have been widely used to facilitate model estimation and variable selection. In this work, we suggest a new K-fold CV procedure to select a candidate ‘optimal’ model from each hold-out ...
  • Cavenagh, Nicholas J. (Electronic Journal of Combinatorics, 2015)
    Let G be an even bipartite graph with partite sets X and Y such that |Y | is even and the minimum degree of a vertex in Y is at least 95|X|/96. Suppose furthermore that the number of edges in G is divisible by 4. Then G ...
  • Litvinenko, Yuri E.; Wheatland, M.S. (The American Astronomical Society, 2015)
    Disintegration of sunspots (and starspots) by fluxtube erosion, originally proposed by Simon and Leighton, is considered. A moving boundary problem is formulated for a nonlinear diffusion equation that describes the sunspot ...
  • Delbourgo, Daniel; Peters, Lloyd (Cambridge University Press, 2015)
    For the (d+1)-dimensional Lie group G=Z×pZp⊕d we determine through the use of p-power congruences a necessary and sufficient set of conditions whereby a collection of abelian L-functions arises from an element in K₁Zp[G]. ...
  • Akram, Raja Naeem; Ko, Ryan K.L. (Institute of Electrical and Electronics Engineers Inc., 2015)
    One of the most crucial components of modern Information Technology (IT) systems is data. It can be argued that the majority of IT systems are built to collect, store, modify, communicate and use data, enabling different ...
  • Akram, Raja Naeem; Ko, Ryan K.L. (IEEE Computer Society, 2015)
    Along with the invention of computers and interconnected networks, physical societal notions like security, trust, and privacy entered the digital environment. The concept of digital environments begins with the trust ...
  • Fitzgerald, Alannah; Wu, Shaoqun; Marín, María José (Research-publishing.net, 2015)
    In this case study we present innovative work in building open corpus-based language collections by focusing on a description of the opensource multilingual Flexible Language Acquisition (FLAX) language project, which is ...
  • Keegan, Te Taka Adrian Gregory; Mato, Paora James; Ruru, Stacey (Ngā Pae o te Māramatanga, 2015)
    Language revitalization theory suggests that one way to improve the health of a language is to increase the number of domains where the language is used. Social network platforms provide a variety of domains where indigenous- ...
  • Luz, Saturnino; Masoodian, Masood; Cesario, Manuel (Taylor & Francis, 2015)
    The development and deployment of information technology, particularly mobile tools, to support collaboration between different groups of healthcare professionals has been viewed as a promising way to improve disease ...
  • Craig, Ian J.D.; Effenberger, Frederic (IOP PUBLISHING LTD, 2014)
    The open problem of how singular current structures form in line-tied, three-dimensional magnetic fields is addressed. A Lagrangian magneto-frictional relaxation method is employed to model the field evolution toward the ...
  • Emslie, A. Gordon; Holman, Gordon D.; Litvinenko, Yuri E. (Institute of Physics Publishing, 2014)
    Electrons accelerated in solar flares are injected into the surrounding plasma, where they are subjected to the influence of collisional (Coulomb) energy losses. Their evolution is modeled by a partial differential equation ...
  • Durrant, Robert J.; Kabán, Ata (Springer Verlag, 2014)
    We prove theoretical guarantees for an averaging-ensemble of randomly projected Fisher linear discriminant classifiers, focusing on the casewhen there are fewer training observations than data dimensions. The specific form ...
  • Matthaeus, William H.; Oughton, Sean; Osman, Kareem T.; Servidio, Sergio; Wan, Minping; Gary, S.P.; Shay, M.A.; Valentini, F.; Roytershteyn, V.; Karimabadi, H.; Chapman, S.C. (American Astronomical Society, 2014)
    The application of linear kinetic treatments to plasma waves, damping, and instability requires favorable inequalities between the associated linear timescales and timescales for nonlinear (e.g., turbulence) evolution. In ...
  • Jung, Yoonsuh; Huang, Jianhua; Hu, Jianhua (Taylor & Francis, 2014)
    In genome-wide association studies, the primary task is to detect biomarkers in the form of Single Nucleotide Polymorphisms (SNPs) that have nontrivial associations with a disease phenotype and some other important ...
  • Yoo, Jae Suk; Kim, Joon Bum; Ro, Sun Kyun; Jung, Yoonsuh; Jung, Sung-Ho; Choo, Suk Jung; Lee, Jae Won; Chung, Cheol Hyun (The Japanese Circulation Society, 2014)
    Background: The clinical benefit of concomitant atrial fibrillation (AF) ablation at the time of aortic valve replacement (AVR) is uncertain. Methods and Results: A total of 124 patients with AF who underwent AVR with ...
  • Lester, Joanne L.; Wessels, Andrew L.; Jung, Yoonsuh (Oncology Nursing Society, 2014)
    Purpose/Objectives: To survey nurses about their knowledge of cancer survivorship care. Design: Descriptive, cross-sectional. Setting: Midwestern comprehensive cancer center. Sample: 223 registered and advanced ...
  • Cunningham, Sally Jo; Nichols, David M. (2014)
    As researchers retire or pass away, the online record of their work and their research careers begins to fragment and fade away. We begin with case studies of four New Zealand Humanities researchers, nearing or at the ends ...
  • Cunningham, Sally Jo; Nichols, David M.; Bainbridge, David; Ali, Hasan (ISMIR, 2014)
    This paper builds an understanding of how music is currently experienced by a social group travelling together in a car - how songs are chosen for playing, how music both reflects and influences the group’s mood and social ...
