Role of vector resistance and grafting infection in Huanglongbing control models
Infectious Disease Modelling, 2023 Citrus huanglongbing (HLB) is one of the most devastating diseases affecting citrus almost worldwide due to the lack of a cure. To better understand the impact of insecticide resistance and grafting infection on the spread of HLB disease, a vector-borne ...

Mathematical and Computational Applications, 2020 In this paper, we introduce a novel localized collocation solver for two-dimensional (2D) phononic crystal analysis. In the proposed collocation solver, the displacement at each node is expressed as a linear combination of T-complete functions in each ...

Mean-field concept and direct numerical simulations of rotating magnetoconvection and the geodynamo [PDF]
, 2006 A comparison is made between mean-field models and direct numerical simulations of rotating magnetoconvection and the geodynamo. The mean-field coefficients are calculated with the fluid velocity taken from the direct numerical simulations. The magnetic fields resulting from mean-field models are then compared with the mean magnetic field from the ...

Investigation of hidden-charm pentaquarks with strangeness $$S=-1$$ S = - 1
European Physical Journal C: Particles and Fields, 2022 Recently, a new hidden-charm pentaquark state $$P_{cs}(4459)$$ P cs ( 4459 ) was reported by the LHCb Collaboration. Stimulated by the fact that all hidden-charm pentaquark states in $$S=0$$ S = 0 systems were successfully studied by the chiral quark ...

Numerical and modeling error assessment of large-eddy simulation using direct-numerical-simulation-aided large-eddy simulation [PDF]
arXiv, 2022 We study the numerical errors of large-eddy simulation (LES) in isotropic and wall-bounded turbulence. A direct-numerical-simulation (DNS)-aided LES formulation, where the subgrid-scale (SGS) term of the LES is computed by using filtered DNS data is introduced.

A resolution criterion based on characteristic timescales for MHD simulations of molecular clouds [PDF]
, 2021 We investigate the effect of numerical magnetic diffusion in magnetohydrodynamic simulations of magnetically supported molecular clouds. To this end, we have performed numerical studies on adaptive mesh isothermal simulations of marginally sub-critical molecular clouds.
