重塑与移换:青春片《五个扑水的少年》的跨文化改编

《五个扑水的少年》翻拍自日本导演矢口史靖的同名电影。该片在创作时自觉呼应本土语境,成功塑造出新时代青年形象,并基于社会现实进行主题转换,切实观照本土青少年的精神需要;同时,对原作中的各类符号进行适宜的替换、添加与沿用,营造出中国化故事氛围,成功实现了跨文化改编。该片的改编实践印证了青春片跨文化翻拍成败的关键在于能否结合本土语境和社会现实进行合理化改编,能否讲述契合中国观众审美经验和情感诉求的本土青春故事。

《五个扑水的少年》的本土化策略

宋灏霖执导的《五个扑水的少年》,翻拍自矢口史靖的同名电影。在原作中,存在很多推动叙事发展的要素,如文化祭、男女分校、风俗店等,显然无法安放于中国的时空环境,而高中男生顶着课业压力投入大量精力练习花样游泳,也是国内观众难以想象的,这些都为改编设置了重重阻碍。宋灏霖通过巧妙改编,不仅完成了叙事逻辑的自洽,而且根据国人的审美习惯,运用本土艺术符号,开掘本土生活经验,从故事层面、视听符号层面乃至审美与文化价值观层面上完成了作品的本土化。

“平成废柴”与“铁拳男人”——从《五个扑水的少年》与《铁拳男人》看体育类型电影的主题实现路径

《五个扑水的少年》(日本,矢口史靖导演)与《铁拳男人》(美国,朗·霍华德导演)是两部时代背景迥异、气质差别鲜明的体育类型电影。在同一电影类型和相似的类型语言基础上,两部影片实现了差异显著的故事主题表达。

“扑水”考辨

文章考释了宋代疑难词语“扑水”,认为“扑水”同“泊水”,是宫廷、庙宇和官署建筑中正殿或厅堂周围接建的房屋,其形制就是早期的抱厦。“扑水”是“颇厦”的方言记音。随着建筑形制的发展变化,“扑水”引申指偏屋,汉语方言中表示偏屋的词语多与“扑水”“颇厦”有着渊源。

水扑翼枢轴位置优化及实验验证

为解决平原河网水动力不足的问题,利用复合谐波运动的仿生水翼在超低扬程工况下进行推水作业,并基于有限体积法(FVM)和重叠动网格技术,通过数值仿真与实验相结合的方法,确定了扑动水翼推水作业时的最佳枢轴位置。结果表明:扑动水翼尾迹流场结构呈现反卡门涡街状态,其尾迹涡街偏斜程度、前缘涡的强度以及每个时刻前缘涡的状态变化均受枢轴位置影响;当枢轴位置向水翼尾部移动时,推水效率先增后减,L=0.2c时效率最佳,相较枢轴位于水翼前缘时,效率可提升2%~5%;扑动水翼的水力特性曲线与传统水泵相似,其最大扬程小于1 m,且随着枢轴位置向水翼尾部移动,其最大扬程呈现减小的趋势,进一步满足了超低扬程工况需求。

Experimental Study on a Cascade Flapping Wing Hydroelectric Power Generator

A hydroelectric power generator, which is able to extract the water flow energy from the hydroelastic response of an elastically supported rectangular wing, is experimentally investigated. An electric motor is used to excite pitching oscillations of the wing. Both the wing and the electric motor are supported by leaf springs which are designed to work both as a linear guide for the sway oscillations and as elastic elements. The wing mass in sway direction necessary to achieve a hydroelastic response is obtained by utilizing a mechanical snubber mechanism. The appropriate load to generate electricity is provided by magnetic dampers. In the previous paper, the generating power rate and the efficiency were examined through the experiments with a single wing model, and the feasibility of the flapping wing hydroelectric power generator was verified. In this paper, the influence of the neighboring wings is examined by using two experimental apparatuses, with the intention of achieving a practical cascade wing generator. Tests revealed that the cascade moving in-phase with the neighboring wings at narrower intervals has a higher rate of electric power generation.

Manipulating the spin configuration by topochemical transformation for optimized intermediates adsorption ability in oxygen evolution reaction

The underlying spin-related mechanism remains unclear,and the rational manipulation of spin states is challenging due to various spin configurations under different coordination conditions.Therefore,it is urgent to study spin-dependent oxygen evolution reaction(OER)performance through a controllable method.Herein,we adopt a topochemical reaction method to synthesize a series of selenides with eg occupancies ranging from 1.67 to 1.37.The process begins with monoclinic-CoSeO_(3),featuring a distinct laminar structure and Co-O6 coordination.The topochemical reaction induces significant changes in the crystal field's intensity,leading to spin state transitions.These transitions are driven by topological changes from a Co-O-Se-O-Co to a Co-Se-Co configuration,strengthening the crystalline field and reducing eg orbital occupancy.This reconfiguration of spin states shifts the rate-determining step from desorption to adsorption for both OER and the hydrogen evolution reaction(HER),reducing the potential-determined step barrier and enhancing overall catalytic efficiency.As a result,the synthesized cobalt selenide exhibits significantly enhanced adsorption capabilities.The material demonstrates impressive overpotentials of 35 mV for HER,250 mV for OER,and 270 mV for overall water splitting,indicating superior catalytic activity and efficiency.Additionally,a negative relation between eg filling and OER catalytic performance confirms the spin-dependent nature of OER.Our findings provide crucial insights into the role of spin state transitions in catalytic performance.

Magnetic-field enhanced high-thermoelectric performance in topological Dirac semimetal Cd3As2 crystal

Thermoelectric materials can be used to convert heat to electric power through the Seebeck effect. We study magneto-thermoelectric figure of merit （ZT） in three-dimensional Dirac semimetal Cd3A 5 2 crystal. It is found that enhancement of power factor and reduction of thermal conductivity can be realized at the same time through magnetic field although magnetoresistivity is greatly increased. ZT can be highly enhanced from 0.17 to 1.1 by more than six times around 350 K under a perpendicular magnetic field of 7 T. The huge enhancement of ZT by magnetic field arises from the linear Dirac band with large Fermi velocity and the large electric thermal conductivity in CdsA 5 2. Our work paves a new way to greatly enhance the thermoelectric performance in the quantum topological materials.

Algorithms for seismic topology optimization of water distribution network

As an essential lifeline engineering system,water distribution network should provide enough water to maintain people's life after earthquake in addition to working under daily operation.However,the design of water distribution network usually ignores the influence of earthquake,resulting in water stoppage in large area during many recent strong earthquakes.This study introduced a seismic design approach of water distribution network,i.e.,topology optimization design.With network topology as the optimization goal and seismic reliability as the constraint,a topology optimization model for designing water distribution network under earthquake is established.Meanwhile,two element investment importance indexes,a pipeline investment importance index and a diameter investment importance index,are introduced to evaluate the importance of pipelines in water distribution network.Then,four combinational optimization algorithms,a genetic algorithm,a simulated annealing genetic algorithm,an ant colony algorithm and a particle swarm algorithm,are introduced to solve this optimization model.Moreover,these optimization algorithms are used to optimize a network with 19 nodes and 27 pipelines.The optimization results of these algorithms are compared with each other.

Injectivity and projectivity in analysis and topology

We give new proofs of many injectivity results in analysis that make more careful use of the duality between abelian C*-algebras and topological spaces. We then extend many of these ideas to incorporate the case of a group action. This approach gives new insight into Hamana's theory of G-injective operator spaces and G-injective envelopes. Our new proofs of these classic results, use only topological methods and eliminate the need for results from the theory of Boolean algebras and AW*-algebras.

Coordinated motion of molecular motors on DNA chains with branch topology

To understand the macroscopic mechanical behaviors of responsive DNA hydrogels integrated with DNA motors,we constructed a state map for the translocation process of a single FtsKc on a single DNA chain at the molecular level and then investigated the movement of single or multiple FtsKc motors on DNA chains with varied branch topologies.Our studies indicate that multiple.FtsKc motors can have coordinated motion,which is mainly due to the force-responsive behavior of individual FtsKc motors.We further suggest the potential application of motors of FtsKc,together with DNA chains of specific branch topology,to serve as strain sensors in hydrogels.

Design of single-axis flexure hinges using continuum topology optimization method

The design of compliant hinges has been extensively studied in the size and shape level in the literature.This paper presents a method for designing the single-axis flexure hinges in the topology level.Two kinds of hinges,that is,the translational hinge and the revolute hinge,are studied.The basic optimization models are developed for topology optimization of the translational hinge and the revolute hinge,respectively.The objective for topology optimization of flexure hinges is to maximize the compliance in the desired direction meanwhile minimizing the compliances in the other directions.The constraints for accomplishing the translational and revolute requirements are developed.The popular Solid Isotropic Material with Penalization method is used to find the optimal flexure hinge topology within a given design domain.Numerical results are performed to illustrate the validity of the proposed method.

Topology optimization of supporting structure for seismic response reduction of an arch

A flexible supporting structure that reduces seismic response of an arch is proposed. Topology and cross-sectional areas of the supporting structure modeled as a truss structure are optimized through two steps of static and dynamic optimization problems. In the first step, a flexible supporting structure that has diagonal displacement at the top under horizontal load is obtained by solving static optimization problems. Then, in the second step, the cross-sectional area of the flexible member is optimized to minimize the seismic response acceleration of the arch evaluated by the complete quadratic combination(CQC) method. Time-history seismic response analysis is carried out to show that the response in the normal direction of the roof successfully decreases due to flexibility of the supporting structure; in addition, installing passive energy dissipation devices into the flexible supporting structure is very effective in reducing the tangential response of the arch.
