  • A wide class of Combinatorial matrices related with Reciprocal Pascal and Super Catalan matrices 

    Kilic, Emrah; Prodinger, Helmut (2019)

  • Prejudice, privilege, and power : conflicts and cooperation between recognizable groups 

    Bingham, Jeremy; Landi, Pietro; Hui, Cang (AIMS Press, 2019)
    The problem of cooperation remains one of the fundamental questions in the fields of biology, sociology, and economics. The emergence and maintenance of cooperation are naturally affected by group dynamics, since individuals ...
  • A complete study of the ramification for any separable cubic global function field 

    Marques, Sophie; Ward, Jacob (Springer, 2019)
    We explicitly describe the ramified places in any separable cubic extension of a cubic global function field in terms of a unique given parameter. This is all done using the uniqueness of the purely cubic closure, which ...

    We study the rare fluctuations or large deviations of time-integrated functionals or observables of an unbiased random walk evolving on Erdös-Rényi random graphs, and construct a modified, biased random walk that explains ...
  • Mixed convective flow of a visco elastic fluid between two porous parellel plates 

    Kumar, D. Satish; Murthy, C. H. V. Ramana; Anusha, S.; Makinde, Oluwole D. (Blue Eyes Intelligence Engineering and Sciences Publication, 2019)

  • On the centroid of increasing trees 

    Durant, Kevin; Wagner, Stephan (Episciences.org, 2019)
    A centroid node in a tree is a node for which the sum of the distances to all other nodes attains its minimum, or equivalently a node with the property that none of its branches contains more than half of the other nodes. ...
  • Quadratic Pade approximation : numerical aspects and applications 

    Fasondini, M.; Hale, N.; Spoerer, R.; Weideman, J. A. C. (Steklov Mathematical Institute, 2019)
    Pad´e approximation is a useful tool for extracting singularity information from a power series. A linear Pad´e approximant is a rational function and can provide estimates of pole and zero locations in the complex plane. ...
  • On the inducibility of small trees 

    Dossou-Olory, Audace A. V.; Wagner, Stephan (Episciences, 2019)
    The quantity that captures the asymptotic value of the maximum number of appearances of a given topological tree (a rooted tree with no vertices of outdegree 1) S with k leaves in an arbitrary tree with sufficiently large ...
  • Exponential damping : the key to successful containment of COVID-19 

    Zhang, Feng; Zhang, Jinmei; Cao, Menglan; Zhang, Yong; Hui, Cang (Frontiers Media, 2021-01-08)
    Due to its excessive capacity for human-to-human transmission, the 2019 coronavirus disease (COVID-19) has now been declared a global public health emergency. Here we propose a simple model based on exponential infectious ...
  • Impact of COVID-19 pandemic on mobility in ten countries and associated perceived risk for all transport modes 

    Barbieri, Diego Maria; Lou, Baowen; Passavanti, Marco; Hui, Cang; Hoff, Inge; Lessa, Daniela Antunes; Sikka, Gaurav; Chang, Kevin; Gupta, Akshay; Fang, Kevin (PLOS, 2021-02-01)
    The restrictive measures implemented in response to the COVID-19 pandemic have triggered sudden massive changes to travel behaviors of people all around the world. This study examines the individual mobility patterns for ...
  • Scaling relationships between leaf shape and area of 12 rosaceae species 

    Yu, Xiaojing; Hui, Cang; Sandhu, Hardev S.; Lin, Zhiyi; Shi, Peijian (MDPI, 2019)
    Leaf surface area (A) and leaf shape have been demonstrated to be closely correlated with photosynthetic rates. The scaling relationship between leaf biomass (both dry weight and fresh weight) and A has been widely studied. ...
  • Effects of salt stress on the leaf shape and scaling of pyrus betulifolia bunge 

    Yu, Xiaojing; Shi, Peijian; Hui, Cang; Miao, Lifei; Liu, Changlai; Zhang, Qiuyue; Feng, Chaonian (MDPI, 2019)
    Leaf shape can reflect the survival and development of plants in different environments. In particular, leaf area, showing a scaling relationship with other leaf-shape indices, has been used to evaluate the extent of salt ...
  • Near-vector spaces determined by finite fields and their fibrations 

    Howell, Karin-Therese (Scientific and Technological Research Council of TurkeyScientific and Technological Research Council of Turkey, 2019)
    In this paper we study near-vector spaces constructed from copies of finite fields. We show that for these near-vector spaces regularity is equivalent to the quasikernel being the entire space. As a second focus, we study ...
  • 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 ...
