Drug-eluting stents: is it the beginning of the end for coronary artery bypass surgery?

Chinese medical Journal 2004年第9期117卷 1377-1387页

作者： shahzad G Raja Department of Cardiac Surgery Royal Hospital for Sick Children Yorkhill NHS TrustGlasgow G3 8SJScotland

myocardial revascularization therapy of coronary artery disease is one of the most important medical advances of the past 50 years.1 Coronary revascularization by either bypass surgery or coronary angioplasty relieves angina and may improve the prognosis in patients with coronary artery disease.2,3 Randomized comparisons reveal no difference in survival free from myocardial infarction (mI) between surgery and balloon angioplasty.4,5 Stenting significantly improved the long-term outcome, while surgery is still associated with fewer reinterventions during follow-up.6-10 However, subsequent improvements in both percutaneous and surgical techniques may now limit the validity of any conclusions that have been drawn from the earlier studies. In fact, the lines of demarcation for patients suited for bypass or angioplasty are becoming blurry with each passing day.

作者： Khurram shahzad SANA Weiduo HU School of Astronautics Beihang UniversityBeijing 102206China

This paper proposes a novel hybrid algorithm called Fractional-order Particle Swarm optimization Gravitational Search Algorithm(FPSOGSA)and applies it to the trajectory planning of the hypersonic lifting reentry flight *** proposed method is used to calculate the control profiles to achieve the two objectives,namely a smoother trajectory and enforcement of the path constraints with terminal *** smoothness of the trajectory is achieved by scheduling the bank angle with the aid of a modified scheme known as a Quasi-Equilibrium Glide(QEG)*** aerodynamic load factor and the dynamic pressure path constraints are enforced by further planning of the bank angle with the help of a constraint enforcement *** maximum heating rate path constraint is enforced through the angle of attack *** Common Aero Vehicle(CAV)flight vehicle is used for the simulation purpose to test and compare the proposed method with that of the standard Particle Swarm Optimization(PSO)method and the standard Gravitational Search Algorithm(GSA).The simulation results confirm the efficiency of the proposed FPSOGSA method over the standard PSO and the GSA methods by showing its better convergence and computation efficiency.

Bulk moduli of two-dimensional Yukawa solids and liquids obtained from periodic compressions

Plasma Science and Technology 2023年第3期25卷 15-20页

Langevin dynamical simulations are performed to determine the bulk modulus in twodimensional(2D) dusty plasmas from uniform periodic radial compressions. The bulk modulus is calculated directly from its physical definition of the ratio of the internal pressure/stress to the volume strain. Under various conditions, the bulk moduli obtained agree with the previous theoretical derivations from completely different approaches. It is found that the bulk moduli of2D Yukawa solids and liquids are almost independent of the system temperature and the external compressional frequency.

Elastic-viscoplastic constitutive model for capturing the mechanical response of polymer composite at various strain rates

引用

Journal of materials Science & Technology 2020年第22期54卷 12-17页

作者： shahzad Fateh Ali Jitang Fan State Key Laboratory of Explosion Science and Technology Beijing Institute of TechnologyBeijing700087China

Recently, polymer composites, consisting of hard segments and soft segments blend, attract a broad research interest because of the high flow stress and large deformation under a high rate loading. They display an outstanding energy absorption capability for impact resistant engineering. In this paper,a physics-based elastic-viscoplastic constitutive model is developed which accounts the activation of molecular chains motion at different segments upon an applied stress as well as the rate dependency of mechanical properties. Accordingly, finite element simulations are conducted to derive the mechanical performance at various strain rates. It involves the linearly elastic deformation to yielding, softening behavior with a slight decrease of stress, plastic flow at a plateau stress accompanied by a considerable straining, densification with a fast increase of stress. The results achieved from model simulations match well with these obtained by experiments and the mechanical response in the strain rate range from 0.0001 s^(-1) to 8000 s^(-1) can be captured by this model. Finally, energy absorption capability of the polymer composite is discussed, and the physical mechanisms in material science are addressed by post-loading analysis. This work is full of interest to develop the constitutive model for designing the impact-resistant polymers and illustrating the dynamic mechanical response, which will promote the application of light-weight transparent protection structure against a high-speed impact.

Thermodynamic Characteristics of Dusty Plasma Studied by Using molecular Dynamics Simulation

引用

Plasma Science and Technology 2012年第9期14卷 771-777页

作者： Aamir shahzad 何茂刚 Key Laboratory of Thermo-Fluid Science and Engineering of ministry of Education(mOE) Xi'an Jiaotong University Department of Physics Government College University Faisalabad(GCUF)Allama Iqbal RoadFaisalabad 38000Pakistan

Thermodynamic properties of a Debye-Yukawa system of particles are explored by using molecular dynamics simulation in the canonical ensemble. The excess free energy f of the Debye-Yukawa system is calculated by using two different approaches for the liquid phase, and the energy is obtained in a coupling parameter range of 0 ≤ F ≤100 and a wide range of the screening parameter κ. Simulation measurements for excess internal energy and pressure of the system over dimensionless parameters （κ, F） are also presented and compared with previous theoretical and simulated results. A F-expansion-fitting approach for the liquid phase is introduced with the expansion coefficients, which are functions of the screening parameter κ. The fitting coefficients are obtained by directly comparing them with the simulation measurements with a relative deviation of 1% or less. It is shown that the computational results provide a relatively simple method to calculate the excess internal energy and free energy in certain cases, which depend strongly on Г.
