Abstract :
Inorganic solid electrolyte-based all-solid-state lithium-sulfur batteries (ASSLSBs) have garnered significant attention due to their inherent safety and higher energy density, making them a promising candidate for the upcoming lithium batteries. However, employing sulfur as the active material in all-solid-state composite cathodes introduces two critical challenges: sluggish electrochemical reaction kinetics and insufficient solid-solid contact between the sulfur, conductive additive, and solid electrolyte phases. These issues directly impact battery performance and hinder the commercialization of ASSLSBs. In this comprehensive review, the underlying causes of these issues are first discussed to gain a fundamental understanding of potential improvement directions. Subsequently, we summarize the recent progress in enhancing sulfur reaction kinetics and optimizing solid-solid contact. The fundamental principles, fabrication techniques, and resultant performance enhancement of diverse strategies are systematically categorized, summarized, and evaluated. Finally, the challenges and future outlook of advanced ASSLSB cathode research are discussed at the end of this review.

Abstract :
All-solid-state batteries (ASSBs) with high-energy-density and enhanced safety are ideal for next-generation energy storage in electric transportation and Internet of Things. Fundamentally, the augmentation of their energy density relays on advanced cathode materials. This imperative has driven growing interest in Se-based cathodes, which demonstrate a high volumetric energy density, as well as higher electrical conductivity and better environmental adaptability compared to the well-known S cathodes. However, to ensure sufficient mechanical strength and mitigate the continuous deterioration of the solid-solid interface caused by the substantial volume expansion of the Se, the all-solid-state Li-Se batteries reported thus far typically employ thick solid electrolytes (50-200 mu m), which severely limits their energy density. Here, the first successful fabrication of all-solid-state thin-film Li-Se batteries is reported, featuring an ultra-thin (approximate to 1.4 mu m) lithium phosphorus oxynitride solid electrolyte and a hybrid Se cathode supported by vertical graphene nanoarrays (VGs). The conductive VGs, serving as the Se host, effectively mitigate the volume change during cycling and ensure stable solid-solid contact. Consequently, the cells exhibit over 1000 stable cycles with a capacity retention rate of 89% are attained in the "all-thin film" configuration. This study provides a novel design strategy for the development of next-generation high-performance ASSBs.

借助前期研制的张拉仿生机器鱼,通过实验初步探索鱼体的身体刚度分布与鱼体波参数之间的关系.使用鱼体波重构方法,获取张拉机器鱼在频率为 1.87 Hz时不同刚度分布下的鱼体波参数.实验结果表明,摆幅、相位、波速和曲率与刚度分布之间存在关系.通过调整机器鱼的刚度分布,波速最大可提高约 21.5%,并且可以实现与真实鱼类相似的摆幅和改变最大曲率发生的位置.非均匀刚度分布在改变摆幅等方面存在优势.机器鱼第 4 关节的刚度对波速具有较大影响,但对曲率影响较小.刚度分布与鱼体波参数的相关性有助于机器鱼通过控制身体刚度优化鱼体波参数,提高游动性能.

Abstract :
Micro energy sources as the nucleus of intelligent microdevices guarantee their full autonomy in the dimensions of time and space. However, the state-of-the-art micro energy storage components, like all-solid-state thin-film microbatteries (ASSTFBs), whose direct integration is impeded by the stereotyped vacuum-based manufacturing technologies, for which an inevitable high-temperature annealing step (> 500 degrees C) can exert catastrophic effects on the attached microdevices during the crystallization of manufactured insertion thin-film cathodes, especially in flexible integration. Herein, a prototype construction is created to benchmark concrete feasibility for the low-temperature manufacturing of ASSTFBs via a nonvacuum-based spin-coating electrode architecture. Results show that the spin-coated LiFePO4 films enable low-temperature (approximate to 45 degrees C) manufacturing of ASSTFBs, by which it can deliver excellent cycling performance up to 1000 cycles. Importantly, this technology presents the versatility of integrating various cathode composites into ASSTFBs and is therefore generalized to the LiCoO2- and Li4Ti5O12-based solid-state chemistries. Furthermore, ASSTFBs with such compliant electrodes manifest outstanding flexibility without pronounced capacity degradation by successfully integrating on flexible temperature-sensitive substrates. The spin-coating protocol provides a general solution for excessive processing temperatures and ample opportunities for the development of on-chip integratable and flexible ASSTFBs.

Abstract :
Short-term water demand forecasting is essential for ensuring the sustainable use of water resources. The accuracy of water demand forecasting directly impacts the rationality of water resources management and the effectiveness of scheduling. Therefore, it is vital to accurately forecast water demand across various timescales. Based on this motivation, we propose an improved patch time series Transformer (PatchTST) model to forecast the multi-timescale short-term water demand. By introducing relative positional encoding (RPE), the model effectively learns the relationships between tokens. The model combines the global token information capture ability of the self-attention mechanism with the local token information capture ability of the convolutional network to enhance feature extraction abilities. Additionally, the model integrates the advantages of patch-wise and series-wise representation, enabling it to simultaneously capture both local and global dependencies in time series. We utilize historical data collected from district metering area to experimentally validate the effectiveness of the proposed model. Compared with one-dimensional convolutional neural network (1D-CNN), long shortterm memory (LSTM), Transformer, DLinear, and PatchTST models, our model demonstrates superior performance across all five forecasting scales. Finally, the effectiveness of the proposed design is further validated through ablation experiments.

Abstract :
Concurrent multipath transmission provides an effective solution for streaming high-quality mobile videos in heterogeneous wireless networks. Rate control is commonly adopted in multimedia communication systems to fully utilize the available network bandwidth. This paper proposes a novel rate control for concurrent multipath video transmission. The existing rate control algorithms mainly adapt bit rate in the short-term pattern, i.e., without considering the long-term video transmission quality. We propose a long-term rate control scheme that takes into account the status of both the transmission buffer and video frames. First, a mathematical model is developed to formulate the non-convex problem of long-term quality maximization. Second, we develop a dynamic programming solution for online encoding bit rate control based on buffer status. The performance evaluation is conducted in a real test bed over LTE and Wi-Fi networks. Experimental results demonstrate that the proposed long-term rate control scheme achieves appreciable improvements over the short-term rate control schemes in terms of video quality and delay performance.
