Master robots are integral components of teleoperated robot-assisted minimally invasive surgery systems.Among them,parallel mechanism-based 6-degree-of-freedom master robots are distinguished by low inertia and high-force feedback.However,complex kinematics and singularities are the main barriers limiting its usage.This study converts the Hexa-type 6-RUS mechanism into a master robot to construct master-slave teleoperation system.The clinical background is briefly introduced and a representative surgical robot is employed to analyze the master-slave mapping relationship.The inverse/forward kinematics,the Jacobian matrix,and the translation and orientation workspace are derived as the bases of master robot’s application.The architecture parameters are optimized by the global transmission index to achieve better motion/force transmissibility.Based on the optimal result,the prototype and the master-slave control loop are constructed.Finally,the corresponding master-slave teleoperation experiment and model experiment demonstrate that the proposed master robot satisfies the basic need for medical application. 展开更多

Ultraviolet nanoimprint lithography(UV-NIL)is a versatile and cost-effective technique for the fabrication of micro-and nanostructures by copying master patterns in a planar or a roll-to-roll process through curing of a liquid UV-sensitive precursor.For applications with a high pattern complexity,new UV-NIL process chains must be specified.Master fabrication is a challenging part of the development and often cannot be accomplished using a single master fabrication technique.Therefore,an approach combining different patterning fabrication techniques is developed here for polymer masters using laser direct writing and photolithography.The polymer masters produced in this way are molded into inverse silicone stamps that are used for roll-to-roll replication into an acrylate formulation.To fit the required roller size for large-area UV-NIL,several submasters with micrometer-sized dot and line gratings and prism arrays,which have been patterned by these different techniques,are assembled to final size of ~200×600 mm^(2) with an absolute precision of better than 50μm.The size of the submasters allows the use of standard laboratory equipment for patterning and direct writing,thus enabling the fabrication of micro-and even nanostructures when electron-beam writing is utilized.In this way,the effort,time,and costs for the fabrication of masters for UV-NIL processes are reduced,enabling further development for particular structures and applications.Using this approach,patterns fabricated with different laboratory tools are finally replicated by UV-NIL in an acrylate formulation,demonstrating the high quality of the whole process chain. 展开更多

Near-eutectic Al-Si alloys are widely used in automotive manufacturing due to their superior wear resistance and high temperature performance.Because of high Si content,the grain refinement of near-eutectic Al-Si alloy has been a problem for many years.In this study,the effect of deep cryogenic treatment(DCT)on the microstructure and mechanical properties of Al-12Si-4Cu-2Ni-Mg alloy with addition of Al-Ti-C-B master alloy was fully investigated.Results show that the average grain size of the alloy is greatly reduced from 0.92 mm to 0.50 mm,and the eutectic Si and Al7Cu4Ni precipitates are spheroidized and refined in Al-12Si-4Cu-2Ni-Mg after DCT for 24 h and aging treatment.Thereby these changes of microstructures result in a significant increment of about 22.5%in elongation and a slight enhancement of about 6.8%in tensile strength.Moreover,the refinement of microstructure also significantly improves the fatigue life of the alloy. 展开更多

Based on thermodynamic calculations and continuous rheological extrusion(CRE)technology,Al-Ti-V-B master alloys were designed and prepared.The morphology and the distribution of the refined phases in the master alloys were analyzed by XRD,SEM,and TEM.The effects of master alloy addition and holding time on the microstructure and mechanical properties of A356 alloy were investigated.Under the optimum refiner addition of 0.3wt.%and the holding time of 20 min,the average grain size of the refined A356 alloy is 151.8±9.11μm,89.62%lower than that of original A356 alloy.The tensile strength and elongation of as-cast A356refined alloy are 196.11 MPa and 5.75%,respectively.After T6 treatment,the tensile strength and elongation of A356 refined alloy are 290.1 MPa and 3.09%,respectively.The fracture morphology is characterized by a predominance of along-crystal fracture with a small amount of through-crystal fracture,attributed to the refined grains.Finer grains promote crack path deflection and localized plastic deformation,enhancing energy dissipation and reducing the tendency for brittle fracture.This study provides a novel approach to improving the mechanical properties of A356 alloy through grain refinement using CRE Al-Ti-V-B master alloy. 展开更多

Practical jurisprudence is a completely new proposition in legal education and research.The introduction of the concept of“practical jurisprudence”in the teaching of the Civil Procedure Law of the People’s Republic of China(the“Civil Procedure Law”)is a major innovation in terms of values and methodology.Practical jurisprudence focuses more on practical issues,Chinese characteristics,and major needs,while strengthening the practical nature of the Civil Procedure Law.China’s traditional education system for juris masters(for non-law graduates)(“non-law JMs”)emphasizes the development of foundational legal theoretical knowledge.However,it has not fully achieved its goal of cultivating interdisciplinary and practical legal professionals.Therefore,the traditional education system for the Civil Procedure Law needs reconstruction and supplementation through the practical jurisprudence teaching system in the following areas:(a)System composition:The focus should be on the eight tertiary subsystems under the two secondary subsystems—“the knowledge teaching system and the practical teaching system”of practical jurisprudence in the Civil Procedure Law,as well as the management of their interrelationships.(b)Credit structure:The proportion of credits for“practical teaching and training”should be increased.(c)Practical ability requirements:Legal professionals should be cultivated according to the standards for juris masters(for law graduates)as stipulated by the Law of the People’s Republic of China on Academic Degrees.(d)Practice evaluation:“Formalization of the evaluations,”“homogeneity of the evaluators,”and“reliance on written formats”should be avoided. 展开更多

Under the current medical education reform,the“clinical-research”model for TCM master’s degrees is a key approach to advancing the modernization of traditional Chinese medicine.With the core of“dual-track integration,”this model aims to enhance both clinical practice and research abilities simultaneously.However,ten years of practice have shown that it still faces multiple challenges:an imbalance between clinical rotation time and research investment,deeply rooted attitudes that prioritize clinical work over research,insufficient TCM research resources and fragmented platforms,and poor coordination between policy and teaching design.These issues,particularly the methodological differences between TCM experience-based medicine and modern evidence-based medicine,further complicate the integration of clinical and research efforts.Therefore,there is an urgent need to promote the deep integration of research training into clinical practice through system design,value orientation,and evaluation systems,fostering a new ecological environment where clinical and research efforts thrive together.This will help cultivate TCM professionals with both strong clinical skills and innovative research capabilities,providing sustained momentum for the high-quality development of traditional Chinese medicine. 展开更多
