The decision of local people's congresses to discuss major issues is a basic right granted to local people's congresses by the Chinese Constitution and laws.However,in practice,the implementation of the power of deliberation of major issues by local people's congresses is worrying.By applying the theory of Chinese traditionalism and unity in the theory of law,the theory of"sovereignty in the people"in the social contract theory of Western natural law school,Austin's"legal command theory55 in Western positivist law and Hart's"recognition""Rules theory"to argue that the integrity of rights necessarily involves the dual factors of decision-making and execution.At the same time,the existence and operation of the law always reflects the development of the political system.The realistic political situation requires us to make more precise and meticulous refinement of the external form and specific technical links of the legal system,and to coordinate the rules to make up the legal theory and Conflicts and conflicts in legal practice help to reform social institutions. 展开更多

Since The Big Bang Theory was introduced to our country, it has been warmly welcomed. It is its unique contents, characters of distinctive personalities, and humorous dialogues that enable it to be one of the most popular sitcoms now. The success of The Big Bang Theory is not only because of its own artistic charm but also because of its skillful and accurate subtitle translation. Chinese audience can learn about social values of foreign countries and also improve their oral English through subtitle translation. Therefore, subtitle translation is especially important. The thesis takes the subtitle translation of The Big Bang Theory as the example to analyze how subtitle translation helps audience to understand and enjoy the humorous dialogues from the perspective of Functional Equivalence Theory. Based on exemplification, the thesis discusses the principles and procedures in the subtitle translation from the aspects of linguistic, stylistic, and cultural equivalence to help people to better understand the subtitle translation and promote Chinese-English cultural communication. 展开更多

Objective:The aim of this article is to reflect on the role of theater nurses in a multidisciplinary team,understand the factors that have influenced theater nurses’practice,and improve the authors’clinical practice ultimately.Methods:The author used Smyth’s model to guide the process of reflection on the practice issue.Critical reflection,critical emancipatory theory,reflexivity,and critical social theory were used to help the author analyze the factors that have affected theater nurses’practice in the organization.Results:There are gaps between the espoused and enacted theories.A theater nurse’s practice is determined by multiple factors,such as political,structural,social,historical,cultural issues,and so on.The hierarchy of the health context could hinder possible changes in theater nurses’practice.To better understand our practice and implement transformation,we should shape a supportive environment,bear in mind the practice motto of“patient-centered”care,and improve our knowledge and reflection skills.Conclusions:Reflection plays a significant role in the advancing of practice among theater nurses and needs to be combined with clinical practice.To provide the best service of care to perioperative patients,a theater nurse should have an insightful understanding of the factors that have influenced her/his behaviors historically,socially,and culturally.By improving their critical reflection skills,practitioners could gain knowledge from experience. 展开更多

Advances on bidirectional intelligence are overviewed along three threads,with extensions and new perspectives.The first thread is about bidirectional learning architecture,exploring five dualities that enable Lmser six cognitive functions and provide new perspectives on which a lot of extensions and particularlly flexible Lmser are proposed.Interestingly,either or two of these dualities actually takes an important role in recent models such as U-net,ResNet,and Dense Net.The second thread is about bidirectional learning principles unified by best yIng-yAng(IA)harmony in BYY system.After getting insights on deep bidirectional learning from a bird-viewing on existing typical learning principles from one or both of the inward and outward directions,maximum likelihood,variational principle,and several other learning principles are summarised as exemplars of the BYY learning,with new perspectives on advanced topics.The third thread further proceeds to deep bidirectional intelligence,driven by long term dynamics(LTD)for parameter learning and short term dynamics(STD)for image thinking and rational thinking in harmony.Image thinking deals with information flow of continuously valued arrays and especially image sequence,as if thinking was displayed in the real world,exemplified by the flow from inward encoding/cognition to outward reconstruction/transformation performed in Lmser learning and BYY learning.In contrast,rational thinking handles symbolic strings or discretely valued vectors,performing uncertainty reasoning and problem solving.In particular,a general thesis is proposed for bidirectional intelligence,featured by BYY intelligence potential theory(BYY-IPT)and nine essential dualities in architecture,fundamentals,and implementation,respectively.Then,problems of combinatorial solving and uncertainty reasoning are investigated from this BYY IPT perspective.First,variants and extensions are suggested for AlphaGoZero like searching tasks,such as traveling salesman problem(TSP)and attributed graph matching(AGM)that ar 展开更多

The nonlinear vibration characteristics of the piezoelectric circular cylindri- cal nanoshells resting on an elastic foundation are analyzed. The small scale effect and thermo-electro-mechanical loading are taken into account. Based on the nonlocal elastic- ity theory and Donnell’s nonlinear shell theory, the nonlinear governing equations and the corresponding boundary conditions are derived by employing Hamilton’s principle. Then, the Galerkin method is used to transform the governing equations into a set of ordinary differential equations, and subsequently, the multiple-scale method is used to obtain an approximate analytical solution. Finally, an extensive parametric study is conducted to examine the effects of the nonlocal parameter, the external electric potential, the temperature rise, and the Winkler-Pasternak foundation parameters on the nonlinear vibration characteristics of circular cylindrical piezoelectric nanoshells. 展开更多

The current paper presents a thorough study on the pull-in instability of nanoelectromechanical rectangular plates under intermolecular, hydrostatic, and thermal actuations. Based on the Kirchhoff theory along with Eringen’s nonlocal elasticity theory, a nonclassical model is developed. Using the Galerkin method(GM), the governing equation which is a nonlinear partial differential equation(NLPDE) of the fourth order is converted to a nonlinear ordinary differential equation(NLODE) in the time domain. Then, the reduced NLODE is solved analytically by means of the homotopy analysis method. At the end, the effects of model parameters as well as the nonlocal parameter on the deflection, nonlinear frequency, and dynamic pull-in voltage are explored. 展开更多

Humic acid is a key component of extracellular electron acceptor. Experimental study elucidates that humic acid molecular ligand with different metal elements has different abilities to accept electrons. By using density functional theory, this article selected the leonardite humic acid(LHA) organic macromolecule as ligand to study interactions between the ligand and different metals. At the same time, the calculation of binding energy, the analysis of characteristics for the complex structure and the distribution of frontier molecular orbital were also completed. On the basis of Marcus theory, the reorganization energy, matrix element and charge transport rate constant were calculated. The results show that the order of the charge transfer rates is Fe^3+>Cu^2+>Al^3+ for different metal complexes, and are in good agreement with the experimental ones. 展开更多

An extrapolation to the physical limit for the lattice data of Λ_b →Λ_c form factors computed in the nonphysical region is made in this work through a class of fitting functions proposed by us with nonlinear dependence on m2/π derived in the chiral perturbative theory(ChPT) and the heavy quark effective theory(HQET) framework. Then the results are applied to calculate the differential and integrated Λ_b →Λ_c semileptonic decay rates. Meanwhile, a comparison between our results and those obtained through the extrapolation functions with naive linear dependenceon m2/π is made.It is shown that the difference between the extrapolated central values of these two cases is about 5%.The total uncertainties(depending on the momentum transfer q~2) in the linear case are about 5% ~10%(caused by the uncertainties of lattice data) and those in the nonlinear case are about 10% ~ 20%(caused by the uncertainties of both lattice data and input parameters in Ch PT and HQET). More accurate lattice data and parameters in ChPT and HQET are needed to reduce the uncertainties of the extrapolated results. 展开更多

China, the attribute of virtual property rights has changed from real rights to non-real rights. Article No. 127 thereof does not clarify the nature of virtual property rights after all, and the place where virtual property is put in the “Civil Rights” chapter of General Provisions of the Civil Law makes the concept even more complex and confusing. The “relationships paradigm” protection of virtual property does not have a definite classification criterion, nor stands opposite to the “rights paradigm.” There are two different ways to justify the “theory of virtual property as a real right” under the “rights paradigm” protection, namely, essentialism and consequentialism. The former resulted from utilizing features in a demonstration and identifying disposal rights with real rights, while the latter resulted from adherence to the dichotomy system of property rights comprising real rights and creditor’s rights. From the perspective of larceny in Criminal Law and virtual property insurance in The Social Insurance Law, the attribute of virtual property rights is irrelevant to creditor’s rights. The attribute of virtual property rights shall be defined as virtual property rights so that it can be included in the system of civil rights. The uniqueness of virtual property is enough to become an object of emerging civil rights;intangible property rights as a superordinate theoretical concept cannot reflect the essence of virtual property rights. The legislative frame of virtual property rights shall be comprised of the subject, object, exercise, publication and change of the rights. 展开更多

The distribution of dopants significantly influences the properties of semiconductors,yet effective modulation and separation of p-type and n-type dopants in homogeneous materials remain challenging,especially for nanostructures.Employing a bond orbital model with supportive atomistic simulations,we show that axial twisting can substantially modulate the radial distribution of dopants in Si nanowires(NWs)such that dopants of smaller sizes than the host atom prefer atomic sites near the NW core,while dopants of larger sizes are prone to staying adjacent to the NW surface.We attribute such distinct behaviors to the twist-induced inhomogeneous shear strain in NW.With this,our investigation on codoping pairs further reveals that with proper choices of codoping pairs,e.g.B and Sb,n-type and p-type dopants can be well separated along the NW radial dimension.Our findings suggest that twisting may lead to realizations of p–n junction configuration and modulation doping in single-crystalline NWs. 展开更多

This paper deals with geometric error modeling and sensitivity analysis of an overconstrained parallel tracking mechanism. The main contribution is the consideration of overconstrained features that are usually ignored in previous research. The reciprocal property between a motion and a force is applied to tackle this problem in the framework of the screw theory. First of all, a nominal kinematic model of the parallel tracking mechanism is formulated. On this basis, the actual twist of the moving platform is computed through the superposition of the joint twist and geometric errors. The actuation and constrained wrenches of each limb are applied to exclude the joint displacement. After eliminating repeated errors brought by the multiplication of wrenches, a geometric error model of the parallel tracking mechanism is built. Furthermore,two sensitivity indices are defined to select essential geometric errors for future kinematic calibration. Finally, the geometric error model with minimum geometric errors is verified by simulation with SolidWorks software. Two typical poses of the parallel tracking mechanism are selected, and the differences between simulation and calculation results are very small. The results confirm the correctness and accuracy of the geometric error modeling method for over-constrained parallel mechanisms. 展开更多

Warm and ice-rich frozen soil(WIRFS) exhibits lower shear strength due to the weak binding forces between soil particles and ice crystals. To enhance the strength of WIRFS, frozen soil was treated separately with Portland, Phosphate, Sulphoaluminate, Portland-Phosphate and PortlandSulphoaluminate cements. After the samples were cured under -1.0°C for 7 days, the microscopic pore distribution characteristics and the macro-mechanical properties of WIRFS were investigated using mercury intrusion porosimetry(MIP), scanning electron microscopy(SEM) and unconfined compressive strength(UCS) tests. To quantitatively analyze the laws of pore-size transformation and the variation of Hausdorff volumetric fractal dimensions for pre-and post-treated WIRFS, the CURVEEXTRACT and Image-Pro Plus(IPP) image analysis system has been developed for analysing SEM images of the soil samples. Statistics of the pore-area dimension and pore-volume dimension were calculated. The results reveal that the cement-based treatment of WIRFS can improve the cementation fill of soil pores and the bond forces between soil particles. There is an evident correlation between the microstructure characteristics and the mechanical properties of the treated WIRFS. As the fractal dimensions of pore-area decrease, the unconfined compressive strength of cement-treated WIRFS increases significantly. In contrast, as the fractal dimensions of pore-volume increases, the unconfined compressive strength decreases remarkably. 展开更多
