The thermal transport properties of NiNB_(2)O_(6)as anode material for lithium-ion battery and the effect of strain were studied by machine learning interatomic potential combined with Boltzmann transport *** results show that the lattice thermal conductivity of NiNB_(2)O_(6)along the three crystal directions[100],[010],and[001]are 0.947 W·m^(-1)·K^(-1),0.727 W·m^(-1)·K^(-1),and 0.465 W·m^(-1)·K^(-1),respectively,indicating the anisotropy of the lattice thermal conductivity of NiNB_(2)O_(6).This anisotropy of the lattice thermal conductivity stems from the significant difference of phonon group velocities in different crystal directions of NiNB_(2)O_(6).When the tensile strain is applied along the[001]crystal direction,the lattice thermal conductivity in all three directions ***,when the compressive strain is applied,the lattice thermal conductivity in the[100]and[010]crystal directions is increased,while the lattice thermal conductivity in the[001]crystal direction is abnormally reduced due to the significant inhibition of compressive strain on the group *** indicate that the anisotropy of thermal conductivity of NiNB_(2)O_(6)can be enhanced by the compressive strain,and reduced by the tensile strain.

Taking a microwave product as an example, a system of integrated assembly structure design is presented. Getting design constraints from the upstream design section through product data management(PDM), the system generates the assembly scheme using the case? based method, then assigns the design requirements into each component of the assembly. The detail design for each component can be performed under these design constraints. In order to practise concurrent design, the system sends the final design result to the upstream section and downstream section through PDM to achieve information sharing and integration.

随着多媒体和Internet技术的广泛应用和深入普及,多媒体数据的数量正在飞速增长,音频数据作为多媒体数据的重要组成部分,其信息量也在不断膨胀。如何有效的对音频信息进行检索成为现代信息检索的一个重要的研究领域。然而,音频数据同传统的文本数据不同,文本检索中的相关技术不能简单地应用到音频信息检索中,因为后者往往是基于语义的,所以不可避免地要用到音频数据的特征提取和模式匹配等技术。本文将对音频数据检索相关技术和系统做一综述性的介绍。

High-resolution non-emissive displays based on electrochromic tungsten oxides (WOx) are crucial for future near-eye virtual/augmented reality interactions, given their impressive attributes such as high environmental stability, ideal outdoor readability, and low energy consumption. However, the limited intrinsic structure of inorganic materials has presented a significant challenge in achieving precise patterning/pixelation at the micron scale. Here, we successfully developed the direct photolithography for WOx nanoparticles based on in situ photo-induced ligand exchange. This strategy enabled us to achieve ultra-high resolution efficiently (line width m, the best resolution for reported inorganic electrochromic materials). Additionally, the resulting device exhibited impressive electrochromic performance, such as fast response ( 3600 cycles), as well as promising applications in electronic logos, pixelated displays, flexible electronics, etc. The success and advancements presented here are expected to inspire and accelerate research and development (R&D) in high-resolution non-emissive displays and other ultra-fine micro-electronics.

作为新时代乡村治理现代化的发展目标,乡村数字化治理是推进乡村振兴的关键环节。新质生产力赋能乡村数字化治理具有多重实施路径,通过“人的现代化”“物的现代化”“治理的现代化”与“技术的现代化”,立体构成赋能进程的运作机理。在赋能过程中所呈现的实践悖论具体表征为乡村数字化治理需求显现脱节情形、乡村建设基础设施伴生缺失风险、乡村数字化治理专业人才短缺、乡村数字化治理泛起内源动力不足、城乡之间数字鸿沟愈加凸显等客观现象,从而阻滞了乡村数字化治理的实践进程。为消解新质生产力赋能乡村数字化治理的实践偏差,应实现治理内容的有效融合与治理需求的有效对接,助推数字设施的广泛普及与乡村资源的充分开发,推动专业人才的重点培育与治理主体数字素养的全面提升,促进内源动力的有效激活与公共合作精神的最终形成,提升新质技术的发展水平与赋能发展的制度保障。
