Abstract By introducing a delayed fractional-order differential equation model, we deal with the dynamics of the 2 Way 6.5" stability and Hopf bifurcation of a paddy ecosystem with three main components: rice, weeds, and inorganic fertilizer.In the system, there exists an equilibrium for rice and weeds extinction and an equilibrium for rice extinct

The reasonable calculation of ground appropriateness index in permafrost region is the precondition of highway route design in permafrost region.The theory of knowledge base and fuzzy mathematics are applied, and the damage effect of permafrost is Rear Camera Kit considered in the paper.Based on the idea of protecting permafrost the calculation met

We review the current status of general relativistic studies for the coalescence of black hole-neutron star (BH-NS) binaries.First, LADIES ACCESSORIES JEWELLERY procedures for a solution of BH-NS binaries in quasi-equilibrium circular orbits and the numerical results, such as quasi-equilibrium sequence and mass-shedding limit, of the high-precision
