Investigating tetraquarks composed of $$us\bar{d}\bar{b}$$ usd¯b¯ and $$ud\bar{s}\bar{b}$$ uds¯b¯
European Physical Journal C: Particles and Fields, 2019 In the framework of the quark delocalization color screening model, we investigate tetraquarks composed of $$us\bar{d}\bar{b}$$ usd¯b¯ and $$ud\bar{s}\bar{b}$$ uds¯b¯ in two structures: meson-meson structure and diquark–antidiquark structure.

Numerical simulation of inextensible elastic ribbons [PDF]
arXiv, 2019 Using dimensionally reduced models for the numerical simulation of thin objects is highly attractive as this reduces the computational work substantially. The case of narrow thin elastic bands is considered and a convergent finite element discretization for the one-dimensional energy functional together with a fully practical, energy-monotone iterative

Computational Hypersonic Aerodynamics with Emphasis on Earth Reentry Capsules
INCAS Bulletin, 2016 The temperature in the front region of a hypersonic vehicle nose can be extremely high, for example, reaching approximately 11 000 K at a Mach number of 36 (Apollo reentry) due to the bow shock wave.

On the simulation of multibody systems with holonomic constraints [PDF]
arXiv, 2006 We use Lagrangian formalism and jet spaces to derive a computational model to simulate multibody dynamics with holonomic constraints. Our approach avoids the traditional problems of drift-off and spurious oscillations. Hence even long simulations remain physically relevant. We illustrate our method with several numerical examples.

Most Probable Phase Portraits of Stochastic Differential Equations and its Numerical Simulation [PDF]
arXiv, 2017 A practical and accessible introduction to most probable phase portraits is given. The reader is assumed to be familiar with stochastic differential equations and Euler-Maruyama method in numerical simulation. The article first introduce the method to obtain most probable phase portraits and then give its numerical simulation which is based on Euler ...
arxiv
arXiv, 2013 We present different techniques to numerically solve the equations of motion for the widely studied Discrete Nonlinear Schroedinger equation (DNLS). Being a Hamiltonian system, the DNLS requires symplectic routines for an efficient numerical treatment.
