| 1 | Propagations of singularities in a parabolic system with coupling nonlocal sources显示文摘This paper deals with propagations of singularities in solutions to a parabolic system coupled with nonlocal nonlinear sources. The estimates for the four possible blow-up rates as well as the boundary layer profiles are established. The critical exponent of the system is determined also. | ZHANG He KONG LingHua ZHENG SiNing | 2009 | Science China Mathematics2009，52，1： | 10 |
| 2 | Numerical Simulation of a Class of Nonlinear Wave Equations by Lattice Boltzmann Method显示文摘In this paper,we develop a lattice Boltzmann model for a class ofone-dimensional nonlinear wave equations,including the second-order hyperbolictelegraph equation,the nonlinear Klein-Gordon equation,the damped and undampedsine-Gordon equation and double sine-Gordon equation.By choosing properly theconservation condition between the macroscopic quantity u,and the distributionfunctions and applying the Chapman-Enskog expansion,the governing equation isrecovered correctly from the lattice Boltzmann equation.Moreover,the local equilib-rium distribution function is obtained.The results of numerical examples have beencompared with the analytical solutions to confirm the good accuracy and the applica-bility of our scheme. | Yali Duan Linghua Kong Min Guo | 2017 | Communications in Mathematics and Statistics2017，5，1： | 4 |
| 3 | Multisymplectic Fourier pseudo-spectral integrators for Klein-Gordon-Schrdinger equations显示文摘A multisymplectic Fourier pseudo-spectral scheme,which exactly preserves the discrete multisymplectic conservation law,is presented to solve the Klein-Gordon-Schrdinger equations.The scheme is of spectral accuracy in space and of second order in time.The scheme preserves the discrete multisymplectic conservation law and the charge conservation law.Moreover,the residuals of some other conservation laws are derived for the geometric numerical integrator.Extensive numerical simulations illustrate the numerical behavior of the multisymplectic scheme,and demonstrate the correctness of the theoretical analysis. | KONG LingHua WANG Lan JIANG ShanShan DUAN YaLi | 2013 | Science China Mathematics2013，56，5： | 3 |
| 4 | Evaluation of triage strategies for high-risk human papillomavirus-positive women in cervical cancer screening:A multicenter randomized controlled trial in different resource settings in China显示文摘Objective:We aimed to evaluate the effectiveness of different triage strategies for high-risk human papillomavirus(hrHPV)-positive women in primary healthcare settings in China.Methods:This study was undertaken in 11 rural and 9 urban sites.Women aged 35-64 years old were enrolled.HrHPV-positive women were randomly allocated to liquid-based cytology(LBC),visual inspection with acetic acid and Lugol’s iodine(VIA/VILI)(rural only)triage,or directly referred to colposcopy(direct COLP).At 24 months,hrHPV testing,LBC and VIA/VILI were conducted for combined screening.Results:In rural sites,1,949 hrHPV-positive women were analyzed.A total of 852,218 and 480 women were randomly assigned to direct COLP,LBC and VIA/VILI.At baseline,colposcopy referral rates of LBC or VIA/VILI triage could be reduced by 70%-80%.LBC(n=3 and n=7)or VIA/VILI(n=8 and n=26)could significantly decrease the number of colposcopies needed to detect one cervical intraepithelial neoplasia(CIN)2 or worse and CIN3+compared with direct COLP(n=14 and n=23).For the 24-month cumulative detection rate of CIN2+,VIA/VILI triage was 0.50-fold compared with LBC triage and 0.46-fold with the direct COLP.When stratified by age,baseline LBC triage+performed best(P<0.001),peaking among women aged 35-44 years(Ptrend=0.002).In urban sites,1,728 women were hrHPV genotyping test positive.A total of 408,571 and 568women were randomly assigned to direct COLP for HPV16/18+,direct COLP for other hrHPV subtypes+,and LBC triage for other hrHPV subtypes+.LBC(n=12 and n=31)significantly decreased the number of colposcopies needed to detect one CIN2+and CIN3+compared with direct COLP(n=14 and n=44).HPV16/18+increased the 24-month cumulative detection rate of CIN2+(17.89%,P<0.001).Conclusions:LBC triage for hrHPV-positive women in rural settings and direct COLP for HPV16/18+women and LBC triage for other hrHPV subtype+women in urban settings might be feasible strategies. | Le Dang Linghua Kong Yuqian Zhao Yi Dai Li Ma Lihui Wei Shulan Zhang Jihong Liu Mingrong Xi Long Chen Xianzhi Duan Qing Xiao Guzhalinuer Abulizi Guonan Zhang Ying Hong Qi Zhou Xing Xie Li Li Mayinuer Niyazi Zhifen Zhang Jiyu Tuo Yiling Ding Youlin Qiao Jinghe Lang | 2022 | Chinese Journal of Cancer Research2022，34，5： | 2 |
| 5 | Novel Multi-Symplectic Integrators for Nonlinear Fourth-Order Schrodinger Equation with Trapped Term显示文摘The multi-symplectic Runge-Kutta (MSRK) methods and multi-symplecticFourier spectral (MSFS) methods will be employed to solve the fourth-orderSchrodinger equations with trapped term. Using the idea of split-step numericalmethod and the MSRK methods, we devise a new kind of multi-symplectic integrators, which is called split-step multi-symplectic (SSMS) methods. The numerical experiments show that the proposed SSMS methods are more efficient than the conventionalmulti-symplectic integrators with respect to the the numerical accuracy and conservation perserving properties. | Jialin Hong Linghua Kong | 2010 | Communications in Computational Physics2010，7，3： | 2 |

| 11 | Study of Wastewater Advanced Treatment and Reclaimed Water Reuse for a Large General Hospital显示文摘A combined process of biological aerated filter,fiber ball filter and chlorine dioxide disinfection was used to treat effluent of primary hospital wastewater in Jinan.Its treatment capacity was designed as 400m^3/d based on the reclaimed water demand of the large general hospital.The quality of the effluent can meet the requirements of the Reuse of Urban Recycling Water——Water Quality Standard for Urban Miscellaneous Water Consumption(GB/T18920-2002).The project has less site area,low investment and operation cost and high automatic control level,so it can provide scientific references for design and operation of similar projects. | Kong Linghua Chu Guangyi Wang Yonglei Hu Lihua Zheng Yan | 2016 | Meteorological and Environmental Research2016，7，4： | 1 |
| 12 | A Compact Scheme for Coupled Stochastic Nonlinear Schrodinger Equations显示文摘In this paper,we propose a compact scheme to numerically study the coupled stochastic nonlinear Schrodinger equations.We prove that the compact scheme preserves the discrete stochastic multi-symplectic conservation law,discrete charge conservation law and discrete energy evolution law almost surely.Numerical experiments confirm well the theoretical analysis results.Furthermore,we present a detailed numerical investigation of the optical phenomena based on the compact scheme.By numerical experiments for various amplitudes of noise,we find that the noise accelerates the oscillation of the soliton and leads to the decay of the solution amplitudes with respect to time.In particular,if the noise is relatively strong,the soliton will be totally destroyed.Meanwhile,we observe that the phase shift is sensibly modified by the noise.Moreover,the numerical results present inelastic interaction which is different from the deterministic case. | Chuchu Chen Jialin Hong Lihai Ji Linghua Kong | 2017 | Communications in Computational Physics2017，21，1： | 1 |
| 13 | LOD-MS for Gross-Pitaevskii Equation in Bose-Einstein Condensates显示文摘The local one-dimensional multisymplectic scheme(LOD-MS)is developed for the three-dimensional(3D)Gross-Pitaevskii(GP)equation in Bose-Einstein condensates.The idea is originated from the advantages of multisymplectic integrators and from the cheap computational cost of the local one-dimensional(LOD)method.The 3D GP equation is split into three linear LOD Schrodinger equations and an exactly solvable nonlinear Hamiltonian ODE.The three linear LOD Schrodinger equations are multisymplectic which can be approximated by multisymplectic integrator(MI).The conservative properties of the proposed scheme are investigated.It is masspreserving.Surprisingly,the scheme preserves the discrete local energy conservation laws and global energy conservation law if the wave function is variable separable.This is impossible for conventional MIs in nonlinear Hamiltonian context.The numerical results show that the LOD-MS can simulate the original problems very well.They are consistent with the numerical analysis. | Linghua Kong Jialin Hong Jingjing Zhang | 2013 | Communications in Computational Physics2013，14，6： | 1 |
