摘要：在高场磁体中,压缩磁径向应力比拉伸应力更受青睐,原因是它能降低磁体绕组内的整体峰值磁应力.这对于无绝缘高温超导(NI HTS)磁体尤为重要,因为压缩径向应力能够产生良好的匝间接触,这对于无绝缘高温超导线圈中的电流共享以及随之而来的自保护行为至关重要.根据关键磁体设计参数(如目标中心场、背景磁场、内外绕组直径和外部径向堆叠),我们给出了可以从解析上确定高场超导磁体具有压缩径向应力的电磁-力学条件.本文提出的方法可以识别干绕线圈中径向匝间接触行为的3种不同模式:(1)完全分离;(2)完全接触;以及(3)混合模式(即部分分离和接触).文章随后提出一种使用完全压缩径向应力电磁-力学条件来计算干绕线圈中应力分布的解析方法.并通过有限元分析示例验证了解析方法与数值方法的良好一致性.文章结果可以帮助磁体工程师在早期设计阶段更好地概览高场超导磁体的电磁-力学行为.

摘要：Pat Mora＇s House of Houses is a collection of memories about a Southwestern Mexican immigrant family. She develops multilayered meanings of the house in terms of psychological, spiritual, and sensory influences on both her private and communal life. She deploys sensory signiflers to portray religious and spiritual memories in a picturesque or performative way. The book reveals that the primacy of the senses as a perceptual device transforms the habitual religious rituals of popular Catholicism into the unconscious. This book shows how sensory perception is engaged in appropriating mystical space/time and interiorizing spiritual objects of family life. Thus, the paper investigates how the sensory agencies contribute to exploring culturally plural ways of experiencing the divine. It also illustrates how Mora＇s deployment of corporeality is related to her reassessment of femaleness and understanding of a meaning of the divine, which is distinctively embodied through 1o cotidiano. In effect, it focuses on Mora＇s treatment of the sensible body in connection with spiritual and religious connotations.

摘要：Perovskite light-emitting diodes(PeLEDs)have been considered to be the most promising candidate for solid-state lighting and high-definition full-color display due to their attractive properties such as tunable emission wavelengths,narrow full width at half maximum(FWHM),and high photoluminescence quantum yield(PLQY)[1–3].The external quantum efficiencies(EQEs)of greenand red-emitting Pe LEDs have exceeded 20%,rocketing toward the theoretical limit[4,5],but the blue Pe LEDs still suffer from the obstacles of low efficiency and poor operational stability,which largely overshadows their real applications and industrialscale adoption.

摘要：The term ＂ontology＂ is used to describe the nature of reality and demarcates the parameters of existence. An understanding and description of ontology is crucial for academic pursuit as it unveils applicable realities, yet it is often disregarded. The general neglect of ontology provided three motivations for this paper： Firstly, the discussion of the ontological underpinnings in research papers is often neglected while the methodology and methods receive extensive review. Secondly, tertiary students in an academic research-writing course face tremendous difficulty to describe the philosophical ideas that support their interpretation of reality and existence. Thirdly, the philosophical underpinnings of contemporary ontological thought are further complicated by the epistemological challenges posed by the tension between modernism and postmodernism. This paper suggests the use of literature （novels） as a relativity accessible platform to initiate the development of ontological thought. Through a close reading of a sample of Dutch novels published during the last decade of the 20th century, three themes were developed to illuminate the nature of postmodem reality and establish a literary-based ontology. The following three themes were developed： reality as fragments of fiction, reality as dream of paradoxes, and reality as plethora of stories. By using literature as source, ontological thought can be developed to illuminate the extent of the realities acknowledged in research projects.

摘要：The application-specific multiprocessor system-on-chip(MPSoC) architecture is becoming an attractive solution to deal with increasingly complex embedded applications,which require both high performance and flexible programmability. As an effective method for MPSoC development,we present a gradual refinement flow starting from a high-level Simulink model to a synthesizable and executable hardware and software specification. The proposed methodology consists of five different abstract levels:Simulink combined algorithm and architecture model(CAAM),virtual architecture(VA),transactional accurate architecture(TA),virtual prototype(VP) and field-programmable gate array(FPGA) emulation. Experimental results of Motion-JPEG and H.264 show that the proposed gradual refinement flow can generate various MPSoC architectures from an original Simulink model,allowing processor,communication and tasks design space exploration.

摘要：Recent efforts have focused on the fabrication and application of three- dimensional （3-D） nanoarchitecture electrodes, which can exhibit excellent electrochemical performance. Herein, a novel strategy towards the design and synthesis of size- and thickness-tunable two-dimensional （2-D） MnO2 nanosheets on highly conductive one-dimensional （l-D） backbone arrays has been developed via a facile, one-step enhanced chemical bath deposition （ECBD） method at a low temperature （-50 ℃）. Inclusion of an oxidizing agent, BrO3-, in the solution was crucial in controlling the heterogeneous nucleation and growth of the nanosheets, and in inducing the formation of the tailored and uniformly arranged nanosheet arrays. We fabricated supercapacitor devices based on 3-D MnO2 nanosheets with conductive Sb-doped SnO2 nanobelts as the backbone. They achieved a specific capacitance of 162 F·g-1 at an extremely high current density of 20 A·g% and good cycling stability that shows a capacitance retention of -92% of its initial value, along with a coulombic efficiency of almost 100% after 5,000 cycles in an aqueous solution of I M Na2SO4. The results were attributed to the unique hierarchical structures, which provided a short diffusion path of electrolyte ions by means of the 2-D sheets and direct electrical connections to the current collector by 1-D arrays as well as the prevention of aggregation by virtue of the well-aligned 3-D structure.
