  • Bruce, Christina D.; Vanden Berg, Emily R.; Pfoh, Jamie R.; Steinback, Craig D.; Day, Trevor A. (Physiological Reports, 2021)
    Central and peripheral respiratory chemoreceptors are stimulated during voluntary breath holding due to chemostimuli (i.e., hypoxia and hypercapnia) accumulating at the metabolic rate. We hypothesized that voluntary ...
  • del Valle, Coen; Dukes, Peter J.; Garaschuk, Kseniya (arXiv, 2019)
    Motivated by problems involving triangle-decompositions of graphs, we examine the facet structure of the cone τn of weighted graphs on n vertices generated by triangles. Our results include enumeration of facets for small ...
  • Chang, Yanxun; Dukes, Peter J.; Feng, Tao (arXiv, 2019)
    We consider maximum packings of edge-disjoint 4-cliques in the complete graph Kn. When n 1 or 4 (mod 12), these are simply block designs. In other congruence classes, there are necessarily uncovered edges; we examine the ...
  • Dukes, Peter J.; Bowditch, Flora Caroline (arXiv, 2020)
    In a balanced graph decomposition, every vertex of the host graph appears in the same number of blocks. We propose the use of colored loops as a framework for unifying various other types of local balance conditions in ...
  • Dukes, Peter J.; del Valle, Coen; Bailey, Michael (arXiv, 2020)
    It is known that N(n), the maximum number of mutually orthogonal latin squares of order n, satisfies the lower bound N(n) > n1/14.8 for large n. For h > 2, relatively little is known about the quantity N(hn), which denotes ...
  • Dinitz, Jeffrey H.; Dukes, Peter J.; Stinson, Douglas R. (The Electronic Journal of Combinatorics, 2005)
    In this paper, we consider a weakening of the de nitions of uniform and perfect one-factorizations of the complete graph. Basically, we want to order the 2n − 1 one-factors of a one-factorization of the complete graph ...
  • Dukes, Peter J.; MacGillivray, Gary; Parton, Kristin (Contributions to Discrete Mathematics, 2007)
    A complete k-colouring of a hypergraph is an assignment of k colours to the points such that (1) there is no monochromatic hyperedge, and (2) identifying any two colours produces a monochromatic hyperedge. The achromatic ...
  • del Valle, Coen; Dukes, Peter J. (Bulletin of the ICA, 2019)
    The dimension of a block design is the maximum positive integer d such that any d of its points are contained in a proper subdesign. Pairwise balanced designs PBD(v, K) have dimension at least two as long as not all ...
  • Dimoff, Sean A.; Halliday, William D.; Pine, Matthew K.; Tietjen, Krista L.; Juanes, Francis; Baum, Julia K. (Ecological Indicators, 2021)
    Monitoring coral reefs is vital to the conservation of these at-risk ecosystems. While most current monitoring methods are costly and time-intensive, passive acoustic monitoring (PAM) could provide a cost-effective, large ...
  • Chouhan, Devendra; Mishra, Vinod; Srivastava, H.M. (Results in Applied Mathematics, 2021)
    In this paper, generalized fractional-order Bernoulli wavelet functions based on the Bernoulli wavelets are constructed to obtain the numerical solution of problems of anomalous infiltration and diffusion modeling by a ...
  • Gawryluk, Ryan M. R.; Stairs, Courtney W. (Biochimica et Biophysica Aca (BBA) - Bioenergetics, 2021)
    Eukaryotic microbes (protists) that occupy low-oxygen environments often have drastically different mitochondrial metabolism compared to their aerobic relatives. A common theme among many anaerobic protists is the serial ...
  • Srivastava, H.M.; Deniz, Sinan; Saad, Khaled M. (Journal of King Saud University - Science, 2021)
    In this work, the newly developed optimal perturbation iteration technique with Laplace transform is applied to the generalized regularized long wave equations with a new fractional operator to obtain new approximate ...

    Effective cancer therapy requires identification of signaling networks and investigating their potential role in proliferation and invasion of cancer cells. Among molecular pathways, signal transducer and activator of ...
  • Jardon, Mario A.; Rothe, Katharina; Bortnik, Svetlana; Vezenkov, Lubomir; Jiang, Xiaoyan; Young, Robert N.; Lum, Julian J.; Gorski, Sharon M. (Autophagy, 2013)
    Multidisciplinary approaches are increasingly being used to elucidate the role of autophagy in health and disease and to harness it for therapeutic purposes. The broad range of topics included in the program of the Vancouver ...
  • van den Driessche, P.; Yakubu, Abdul-Aziz (Journal of Biological Dynamics, 2018)
    We use a general autonomous discrete-time infectious disease model to extend the next generation matrix approach for calculating the basic reproduction number, R0, to account for populations with locally asymptotically ...
  • Dukes, Peter J.; Ling, Alan C. H.; Malloch, Amanda (The Australasian Journal of Combinatorics, 2016)
    We show that the necessary divisibility conditions for the existence ofaσ-resolvable BIBD(v,k,λ) are sufficient for largev. The key idea isto form an auxiliary graph based on an [r,k]-configuration ...
  • Dukes, Peter J.; Lamken, Esther R.; Ling, Alan C. H. (The Electronic Journal of Combinatorics, 2016)
    We prove that the necessary divisibility conditions are sufficient for the existence of resolvable group divisible designs with a fixed number of sufficiently large groups. Our method combines an application of the Rees ...
  • Dukes, Peter J.; Iwasaki, Kaoruko (Ars Mathematica Contemporanea, 2020)
    An (n3) configuration is an incidence structure equivalent to a linear hypergraph on n vertices which is both 3-regular and 3-uniform. We investigate a variant in which one constraint, say 3-regularity, is present, and we ...
  • Dimoff, Sean (2021-02-05)
    Coral reefs around the world are threatened by a variety of sources, from localized impacts, including overfishing and coastal development, to global temperature increases and ocean acidification. Conserving these marine ...

H.; van Vuuren, Detlef P.; Parkinson, Simon; et al. (Water, 2019)
    Increasing human demands for water, energy, food and materials, are expected to accentuate resource supply challenges over the coming decades. Experience suggests that long-term strategies for a single sector could yield ...
