A generalized variable-coefficient algebraic method is appfied to construct several new families of exact solutions of physical interest for （3＋1）-dimensional Kadomtsev-Petviashvilli （KP） equation. Among them, the Jacobi elliptic periodic solutions exactly degenerate to the soliton solutions at a certain limit condition. Compared with the existing tanh method, the extended tanh method, the Jacobi elliptic function method, and the algebraic method, the proposed method gives new and more general solutions.

In this paper, we present a new rational algebraic approach to uniformly construct a series of exact analytical solutions for nonlinear partial differential equations. Compared with most existing tanh methods and other sophisticated methods, the proposed method not only recovers some known solutions, but also finds some new and general solutions. The solutions obtained in this paper include rational form triangular periodic wave solutions, solitary wave solutions, and elliptic doubly periodic wave solutions. The efficiency of the method can be demonstrated on （2＋1）-dimensional dispersive long-wave equation.

A new approach is presented by means of a new general ansitz and some relations among Jacobian elliptic functions, which enables one to construct more new exact solutions of nonlinear differential-difference equations. As an example, we apply this new method to Hybrid lattice, diseretized mKdV lattice, and modified Volterra lattice. As a result, many exact solutions expressible in rational formal hyperbolic and elliptic functions are conveniently obtained with the help of Maple.

The generalized transformation method is utilized to solve three-dimensional Nizhnik-Novikov-Veselov equation and construct a series of new exact solutions including kink-shaped and bell-shaped soliton solutions, trigonometric function solutions, and Jacobi elliptic doubly periodic solutions. Among them, the Jacobi elliptic periodic wave solutions exactly degenerate to the soliton solutions at a certain limit condition. Compared with the existing tanh methods and Jacobi function method, the method we used here gives more general exact solutions without much extra effort.

It is shown that in an open lambda type atomic system,the gain and dispersion of the probe field are quit sensitive to variation of spontaneously generally coherence （SGC）. The value of the parameter p reflects whether SGC effect exists and the size of SGC effect. Under certain condition, when p = 0. 002, electromagnetically induced transparency occurs; when p≠0. 002, lasing without inversion can be realized;when p = 0.95, high index of the refraction with zero absorption can be obtained.

Surgical robots are designed to provide enhanced precision and dexterity compared to manual surgical procedures,which mainly rely on multimodal sensing technologies for the surgeon to seamlessly operate the robotic arms and *** with single-mode sensors, optical and mechanical bi-modal sensors provide improved precision, enhanced safety,and robustness of human-machine interaction systems. Here, the template-guided and pneumatic printing technologies are combined to construct perovskite and graphene parallel structures with both optical and mechanical sensing capabilities. The printed uniformly crystallized perovskite microstructure exhibits fast and sensitive photoelectric response characteristics,enabling shadow recognition functionality. The combination of graphene and elastic rubber endows the great printability to prepare parallel structures near the perovskite arrays for force sensing capabilities. Thus, the printed perovskite and graphene structures possess non-contact optical sensing capabilities to detect hand position by recognizing shadows between the hand and the sensor, as well as contact mechanical sensing capabilities to detect touch force applied by the hand. It provides a synergistic platform for real-time and multidimensional feedback to improve human-machine interaction.

目的总结中枢神经系统原发性黑色素细胞肿瘤(简称黑色素细胞肿瘤)的临床、影像学和病理学特征,提高对疾病的诊断与鉴别诊断能力。方法与结果纳入2012年1月至2019年10月在广东三九脑科医院诊断与治疗的7例黑色素细胞肿瘤患者,5例手术切除,2例行组织活检术;MRI表现为T1WI高信号,T2WI低信号,FLAIR成像高信号;组织学形态由卵圆形或多边形黑色素细胞构成,胞核偏位,核仁嗜酸性,胞质内含数量不等的色素细胞,细胞异型性不等;免疫组化染色,Melan-A、S-100蛋白呈阳性,HMB-45呈阴性、散在阳性或强阳性。最终诊断为黑色素细胞瘤4例,黑色素瘤1例,弥漫性黑色素细胞增生症1例,黑色素瘤病1例。3例黑色素细胞瘤术后辅以放疗,其中2例分别随访56和116个月状态良好,1例失访;1例未行放疗的黑色素细胞瘤患者总生存期为20个月;1例黑色素瘤患者术后辅以放化疗,总生存期为15个月;1例弥漫性黑色素细胞增生症患者总生存期为13个月;1例黑色素瘤病患者经放化疗后7个月状态良好。结论中枢神经系统原发性黑色素细胞肿瘤罕见,黑色素细胞瘤常见于中老年人,黑色素细胞增生症好发于儿童。肿瘤细胞恒定表达Melan-A和S-100蛋白,而HMB-45表达模式有助于鉴别肿瘤良恶性。肿瘤预后尚不清楚,黑色素细胞瘤预后最好,放疗可获益。
