Numerical Simulation of the Thin Film Coating Flow in Two-Dimension  [PDF]
Zhiyong Liang, Hui Zhou
Open Journal of Fluid Dynamics (OJFD) , 2017, DOI: 10.4236/ojfd.2017.73021
Abstract: Thin film coating is a process of making liquid film cover and deposit base body surface by the way of dipping, spraying, sliding or spin coating, which is a kind of modern surface engineering. It plays an important role in the actual processing, such as improving the surface properties, fine processing, and new surface properties. Analysis of the influence of substrating morphology and fluid flow properties itself on coating fluid motion has an important significance to optimize the thin film coating and improve the quality of the final film. The influence from uneven substrate surface’s geometry configuration on internal motion of the flow field in slip-coating is analyzed by using the FLUENT software as a calculation platform. A two-dimension model of slip coating under isosceles triangle and isosceles trapezoid substrate was established, and thin film coating fluid motions under different configuration parameters were simulated. It is pointed out that the key factor determining the turbulence generation and evolution is the parameter of substrating surface nature. The effects of the change of Reynolds number on turbulent appearance and action area are studied. The velocity contours of fluid field on different substrate surfaces are shown, and the impact of substrate geometry on the backwater region is analyzed.
Recent Developments in Option Pricing  [PDF]
Hui Gong, Aerambamoorthy Thavaneswaran, You Liang
Journal of Mathematical Finance (JMF) , 2011, DOI: 10.4236/jmf.2011.13009
Abstract: In this paper, we investigate recent developments in option pricing based on Black-Scholes processes, pure jump processes, jump diffusion process, and stochastic volatility processes. Results on Black-Scholes model with GARCH volatility (Gong, Thavaneswaran and Singh [1]) and Black-Scholes model with stochastic volatility (Gong, Thavaneswaran and Singh [2]) are studied. Also, recent results on option pricing for jump diffusion processes, partial differential equation (PDE) method together with FFT (fast Fourier transform) approximations of Pillay and O’ Hara [3] and a recently proposed method based on moments of truncated lognormal distribution (Thavaneswaran and Singh [4]) are also discussed in some detail.

A transgenic wheat with a stilbene synthase gene resistant to powdery mildew obtained by biolistic method


科学通报(英文版) , 2000,
Abstract: Stilbene, a kind of phytoalexin, plays an important role in resistance to fungal and bacterial infection in plants. It strongly inhibits the growth of fungi and sprout of spore. Stilbene synthase gene (Vst1) obtained from grapevine has been transferred into common spring wheat Jinghong 5 by using the biolistic transformation method. Five transgenic plants (T0) were obtained from the bombarded 2014 immature embryos. One immune plantlet and 3 plantlets with mid-resistance to powdery mildew were identified from the transgenic plants of T3 generation which came from 2 T0 transgenic plants.
Gynecology and Gynecological Nursing Theories and Practices in Traditional Chinese Medicine: Review on the Ancient Literatures  [PDF]
Xiangeng Zhang, Hui Zhang, Xiaoli Liang, Qin Liu, Miqu Wang
Chinese Medicine (CM) , 2011, DOI: 10.4236/cm.2011.23014
Abstract: Objective: the study is aimed to introduce the developing history of gynecology and gynecological nursing in traditional Chinese medicine (TCM). Study Design: the development of gynecology and gynecological nursing consists of six periods in Chinese history. They are: 1) budding stage represented by the inscriptions of Nü (female) on oracle bones; 2) physiological development stages of women; 3) specialized chapters of gynecology in TCM; 4) features of gynecological nursing; 5) monograph of gynecology and gynecological nursing; 6) integration of ancient gynecological nursing perceptions. Results: TCM has a profound understanding of gynecology and gynecological nursing. For period one, the inscriptions of Nü (female) on oracle bones is the symbol of the budding stage. For period two, physiogenesis stages of women are recorded in The Yellow Emperor of Classics of Inner Medicine. For period three, the specialized chapters of gynecology appeared, represented by Golden Chamber, Woman. For period four, the features of gynecological nursing were elaborated in Essential Prescriptions Worth A Thousand Gold including menstruation, depression, yin-dampness, and menopause. For period five, monographs of gynecology and gynecological nursing represented by Good Comprehensive Woman Formulae appeared. For period six, Integrative studies of gynecological nursing perceptions were carried out with the representation by Integrated Ancient and Modern Books. Conclusion: TCM gynecology and gynecological nursing harbors a long history of treating and nursing gynecological disorders. With therapeutic and nursing modalities, they are effective systems of un-derstanding and managing woman health as proven by medical literatures, clinical benefits and basic research studies.
Ocean Wave Model and Wave Drift Caused by the Asymmetry of Crest and Trough  [PDF]
Jin-Liang Wang, Hui-Feng Li
Open Journal of Marine Science (OJMS) , 2017, DOI: 10.4236/ojms.2017.73025
Abstract: It follows from the review on classical wave models that the asymmetry of crest and trough is the direct cause for wave drift. Based on this, a new model of Lagrangian form is constructed. Relative to the Gerstner model, its improvement is reflected in the horizontal motion which includes an explicit drift term. On the one hand, the depth-decay factor for the new drift accords well with that of the particle’s horizontal velocity. It is more rational than that of Stokes drift. On the other hand, the new formula needs no Taylor expansion as for Stokes drift and is applicable for the waves with big slopes. In addition, the new formula can also yield a more rational magnitude for the surface drift than that of Stokes.

Formation and Radiation Acceleration of Pair Plasmoids Near Galactic Black Holes
Hui Li,Edison P. Liang
Physics , 1995, DOI: 10.1086/176833
Abstract: We study quantitatively the formation and radiation acceleration of electron-positron pair plasmoids produced by photon-photon collisions near Galactic black holes (GBHs). The terminal ejecta velocity is found to be completely determined by the total disk luminosity, proton loading factor and disk size, with no dependence on the initial velocity. We discuss potential applications to the recently discovered Galactic superluminal sources GRS1915, GROJ1655 and possibly other GBHs.
Spin Current and Shot Noise in Single-Molecule Quantum Dots with a Phonon Mode
Hui Yu,J. -Q. Liang
Physics , 2005, DOI: 10.1103/PhysRevB.72.075351
Abstract: In this paper we investigate the spin-current and its shot-noise spectrum in a single-molecule quantum dot coupled with a local phonon mode. We pay special attention on the effect of phonon on the quantum transport property. The spin-polarization dependent current is generated by a rotating magnetic filed applied in the quantum dot. Our results show the remarkable influence of phonon mode on the zero-frequency shot noise. The electron-phonon interaction leads to sideband peaks which are located exactly on the integer number of the phonon frequency and moreover the peak-height is sensitive to the electron-phonon coupling.
