  • A simple ecological model captures the transmission pattern of COVID-19 outbreak in China 

    Zhang, Feng; Zhang, Jinmei; Cao, Menglan; Hui, Cang (BioMed Central, 2020)
    Background The rapid spread of the 2019 novel coronavirus disease (COVID-19), initially reported in the city of Wuhan in China, and quickly transmitted to the entire nation and beyond, has become an international ...
  • Near-vector spaces constructed from near domains 

    Howell, Karin-Therese; Sanon, Sogo Pierre (Miskolci Egyetemi Kiado, 2018)
    In this paper we prove some new results on near-vector spaces and near domains and give a first application of the nearring of quotients with respect to a multiplicative set, namely we construct a new class of near-vector ...
  • Why does not the leaf weight-area allometry of bamboos follow the 3/2-power law? 

    Lin, Shuyan; Shao, Lijuan; Hui, Cang; Song, Yu; Reddy, Gadi V. P.; Gielis, Johan; Li, Fang; Ding, Yulong; Wei, Qiang; Shi, Peijian (Frontiers Media, 2018)
    The principle of similarity (Thompson, 1917) states that the weight of an organism follows the 3/2-power law of its surface area and is proportional to its volume on the condition that the density is constant. However, the ...
  • Spatial segregation facilitates the coexistence of tree species in temperate forests 

    Shi, Peijian; Gao, Jie; Song, Zhaopeng; Liu, Yanhong; Hui, Cang (MDPI, 2018)
    Competition between plants has an important role during the natural succession of forest communities. Niche separation between plants can reduce such interspecific competition and enable multispecies plant to achieve ...
  • Influence of rotation on transversely isotropic piezoelectric rod coated with a thin film 

    Selvamani, Rajendran; Makinde, Oluwole Daniel (Polish Academy of Sciences, 2018)
    In this paper, the influence of rotation on axisymmetric waves of a piezoelectric rod coated with a thin film is studied using constitutive form linear theory elasticity and piezo-electric equations. Potential functions ...
  • On the distribution of subtree orders of a tree 

    Ralaivaosaona, Dimbinaina; Wagner, Stephan (University of Primorska, 2018)
    We investigate the distribution of the number of vertices of a randomly chosen subtree of a tree. Specifically, it is proven that this distribution is close to a Gaussian distribution in an explicitly quantifiable way if ...
  • Upscaling biodiversity : estimating the species–area relationship from small samples 

    Kunin, William E.; Harte, John; He, Fangliang; Hui, Cang; Jobe, R. Todd; Ostling, Annette; Polce, Chiara; Sizling, Arnost; Smith, Adam B.; Smith, Krister; Smart, Simon M.; Storch, David; Tjorve, Even; Ugland, Karl‐Inne; Ulrich, Werner; Varma, Varun (Ecological Society of America, 2018)
    The challenge of biodiversity upscaling, estimating the species richness of a large area from scattered local surveys within it, has attracted increasing interest in recent years, producing a wide range of competing ...
  • Drivers of species turnover vary with species commonness for native and alien plants with different residence times 

    Latombe, Guillaume; Richardson, David M.; Pysek, Petr; Kucera, Tomas; Hui, Cang (Ecological Society of America, 2018)
    Communities comprising alien species with different residence times are natural experiments allowing the assessment of drivers of community assembly over time. Stochastic processes (such as dispersal and fluctuating ...
  • Weighing evidence 

    Muller, M. A. (Author retain copyright, 2019-12)
    Often different pieces of evidence of different degrees of credibility are submitted in legal proceedings. Then a court “weighs” the evidence and arrives at a conclusion. But how should evidence be weighed? The use of ...
  • On spanning sets and generators of near-vector spaces 

    Howell, Karin-Therese; Sanon, Sogo Pierre (Scientific and Technological Research Council of Turkey, 2018)
    In this paper we study the quasi-kernel of certain constructions of near-vector spaces and the span of a vector. We characterize those vectors whose span is one-dimensional and those that generate the whole space.
  • Dynamical phase transition in drifted Brownian motion 

    Nyawo, Pelerine Tsobgni; Touchette, Hugo (American Physical Society, 2018)
    We study the occupation fluctuations of drifted Brownian motion in a closed interval and show that they undergo a dynamical phase transition in the long-time limit without an additional low-noise limit. This phase transition ...
  • The definable (Q, Q)-theorem for distal theories 

    Boxall, Gareth; Kestner, Charlotte (Association for Symbolic Logic, 2018)
    Answering a special case of a question of Chernikov and Simon, we show that any non-dividing formula over a model M in a distal NIP theory is a member of a consistent definable family, definable over M.
  • Hofstadter point spectrum trace and the almost Mathieu operator 

    Ouvry, Stephane; Wagner, Stephan; Wu, Shuang (AIP, 2018)
    We consider point spectrum traces in the Hofstadter model. We show how to recover the full quantum Hofstadter trace by integrating these point spectrum traces with the appropriate free density of states on the lattice. ...
  • Parabolic curve fitting study subject to Joule heating in MHD thermally stratified mixed convection stagnation point flow of Eyring-Powell fluid induced by an inclined cylindrical surface 

    Rehman, Khalil-Ur; Malik, M. Y.; Makinde, O. D. (Elsevier, 2018)
    The current analysis is carried out to envision the properties of magneto-hydrodynamic boundary layer stagnation point flow of Eyring-Powell (non-Newtonian) fluid induced by an inclined stretching cylindrical surface in ...
  • Quantifying multiple-site compositional turnover in an Afrotemperate forest, using zeta diversity 

    Hui, Cang; Vermeulen, Wessel; Durrheim, Graham (SpringerOpen, 2018)
    Background: Species turnover is typically measured by partitioning diversity components into alpha and pairwise beta diversity. However, alpha and beta components cannot express the full spectrum of multiple-site ...
  • Growing and destroying Catalan–Stanley trees 

    Hack, Benjamin; Prodinger, Helmut (Discrete Mathematics and Theoretical Computer Science, 2018)
    Stanley lists the class of Dyck paths where all returns to the axis are of odd length as one of the many objects enumerated by (shifted) Catalan numbers. By the standard bijection in this context, these special Dyck paths ...
  • Modeling top-down and bottom-up drivers of a regime shift in invasive aquatic plant stable states 

    Strange, Emily F.; Landi, Pietro; Hill, Jaclyn M.; Coetzee, Julie A. (Frontiers Media, 2019)
    The evidence for alternate stable states characterized by dominance of either floating or submerged plant dominance is well established. Inspired by an existing model and controlled experiments, we conceptually describe a ...
  • Visibility problems related to skip lists 

    Prodinger, Helmut (Combinatorial Mathematics Society of Australasia, 2018)
    For sequences (words) of geometric random variables, visibility problems related to a sun positioned in the north-west are considered. This leads to a skew version of such words. Various parameters are analyzed, such as ...
  • Evolutionary fields can explain patterns of high-dimensional complexity in ecology 

    Wilsenach, James; Landi, Pietro; Hui, Cang (American Physical Society, 2017)
    One of the properties that make ecological systems so unique is the range of complex behavioral patterns that can be exhibited by even the simplest communities with only a few species. Much of this complexity is commonly ...
  • Representing derivatives of Chebyshev polynomials by Chebyshev polynomials and related questions 

    Prodinger, Helmut (De Gruyter, 2017)
    A recursion formula for derivatives of Chebyshev polynomials is replaced by an explicit formula. Similar formulae are derived for scaled Fibonacci numbers.
