1Primary pulmonary artery chondrosarcoma: the use of different imaging modalities显示文摘Fewer than 300 patients with primary pulmonary artery sarcoma have been reported since 1923,when it was first described by Mandelstamm.1 The diagnosis of pulmonary artery sarcoma is difficult,and misdiagnosis as chronic pulmonary embolism often occurs.Herein,we reported a case of primary pulmonary artery chondrosarcoma.So far as we know,this patient served as the first case ever reported to receive computed tomography pulmonary angiography (CTPA),gadolinium enhanced magnetic resonance imaging (MRI),and positron emission tomography/computed tomography (PET/CT) before surgery.By these means,the utility of different imaging modalities for pulmonary artery sarcoma was well demonstrated.Wang Fengdan Wang Yining Xue Huadan Zhang Yingqiang Sun Jian Miao Qi Zhang Yan 2014Chinese Medical Journal2014,,15:4
2Approximate Controllability of the System Governed by Double Coupled Semilinear Degenerate Parabolic Equations显示文摘This paper concerns the approximate controllability of the initialboundary problem of double coupled semilinear degenerate parabolic equations.The equations are degenerate at the boundary,and the control function acts in the interior of the spacial domain and acts only on one equation.We overcome the difficulty of the degeneracy of the equations to show that the problem is approximately controllable in L2 by means of a fixed point theorem and some compact estimates.That is to say,for any initial and desired data in L2,one can find a control function in L2 such that the weak solution to the problem approximately reaches the desired data in L2 at the terminal time.Chunpeng Wang Fengdan Xu Qian Zhou 2020Communications in Mathematical Research2020,36,4:0
3A SCALAR AUXILIARY VARIABLE (SAV) FINITE ELEMENT NUMERICAL SCHEME FOR THE CAHN-HILLIARD-HELE-SHAW SYSTEM WITH DYNAMIC BOUNDARY CONDITIONS显示文摘In this paper,we consider the Cahn-Hilliard-Hele-Shaw(CHHS)system with the dynamic boundary conditions,in which both the bulk and surface energy parts play important roles.The scalar auxiliary variable approach is introduced for the physical system;the mass conservation and energy dissipation is proved for the CHHS system.Subsequently,a fully discrete SAV finite element scheme is proposed,with the mass conservation and energy dissipation laws established at a theoretical level.In addition,the convergence analysis and error estimate is provided for the proposed SAV numerical scheme.Changhui Yao Fengdan Zhang Cheng Wang 2024Journal of Computational Mathematics2024,42,2:0
