Artificial visual systems can recognize desired objects and information from complex environments, and are therefore highly desired for pattern recognition, object detection, and imaging applications. However, state-of-the-art artificial visual systems with high recognition performances that typically consist of electronic devices face the challenges of requiring huge storage space and high power consumption owing to redundant data. Here, we report a terahertz(THz) frequency-selective surface using a graphene split-ring resonator driven by ferroelectric polarization for efficient visual system applications. The downward polarization of the ferroelectric material offers an ultrahigh electrostatic field for doping p-type graphene with an anticipated Fermi level. By optimizing the geometric parameters of the devices and modulating the carrier behaviors of graphene, our plasmonic devices exhibit a tunable spectral response in a range of 1.7–6.0 THz with continuous transmission values. The alloptical neural network using graphene plasmonic surfaces designed in this study exhibited excellent performance in visual preprocessing and convolutional filtering and achieved an ultrahigh recognition accuracy of up to 99.3% in training the Modified National Institute of Standards and Technology(MNIST) handwritten digit dataset. These features demonstrate the great potential of graphene plasmonic devices for future smart artificial vision systems.

Potassium-ion batteries(PIBs)have garnered significant attention as a promising alternative to commercial lithium-ion batteries(LIBs)due to abundant and cost-efficient potassium ***,the large size of potassium ions and the resulting sluggish reaction kinetics present major obstacles to the widespread use of ***,we present a simple method to ingeniously encapsulate SnS_(2)nanoparticles within sulfurized polyacrylonitrile(SPAN)fibers(SnS_(2)@SPAN)for serving as a high-performance PIB *** large interlayer spacing of SnS_(2)provides a fast transport channel for potassium ions during charge–discharge cycles,while the one-dimensional SPAN skeleton offers massive binding sites and shortens the diffusion path for potassium ions,facilitating faster reaction ***,the excellent ductility of SPAN can effectively accommodate the large volume changes that occur in SnS_(2)upon potassium-ion insertion,thereby enhancing the cyclic stability of SnS_(2).Benefiting from the above advantages,the SnS_(2)@SPAN composites exhibit impressive cyclability over 500 cycles at 4 A g−1,with a capacity retention rate close to 100%.This study provides an effective approach for stabilizing high-capacity PIB anode materials with large volume variations.

近年来,国家大力推动分布式光伏发电,准确可靠的光伏功率预测对于保证大规模分布式光伏接入电网是必不可少的。当前的分布式光伏功率预测方法尚未充分考虑到气象因素的影响,难以提升预测精度。针对上述问题,提出一种基于天气变化过程的自适应分型与匹配的分布式光伏短期功率预测方法。首先通过K-Medoids-Grey实现天气过程的场景划分,再通过改进的多元宇宙算法对卷积神经网络进行优化,实现分布式光伏的短期预测。以中国甘肃省某分布式光伏用户为例进行验证。结果表明,在测试集中,IMVO-CNN方法在聚类情况下的预测精度比不聚类情况下预测精度提高9.83百分点,验证了该方法的有效性。

银行作为我国金融体系中最重要的金融中介机构,其采取的旨在降低个体银行系统性风险的多元化战略成效如何,在理论和实践上都是一个重要话题。本文首次研究了银行贷款业务跨行业投放策略对银行系统性风险的影响。基于上市银行数据的研究发现,贷款跨行业多元化与银行系统性风险显著呈正相关关系,即存在明显的“多元化系统性风险”效应。进一步研究发现,贷款跨行业多元化对银行系统性风险的影响主要通过银行间资产相似性渠道展开。此外,本文发现,“多元化系统性风险”效应主要存在于股份制银行、高同业存款和高房地产贷款的银行中。上述研究发现对目前正在如火如荼开展的控制和防范银行系统性风险的改革和实践具有重要的参考价值。
