光与纳米结构的相互作用一直是纳米光子学的重要研究内容之一,核心部件的纳米结构对光子器件的功能和性能具有决定性作用。纳米光子器件的设计存在两种思路:一是从物理原理出发的直观设计;二是根据所需光学响应探索最优结构的逆设计。近年来,逆设计在纳米器件中取得了一系列重要进展,尤其是最近将深度学习方法引入进来,开启了高性能纳米光子器件智能高效设计的新篇章。文章围绕纳米光子器件智能逆设计方法,分析归纳了这一新兴研究方向的产生背景、重要进展和典型应用,对智能逆设计面临的挑战及未来发展方向进行了展望。

中国三北地区电网风电渗透率较高，同时存在高比例燃煤热电联产机组用于满足冬季巨大的采暖需求，导致其灵活调节能力极其有限，弃风问题十分突出。现有研究尚缺乏对各种类型电采暖负荷促进风电消纳的经济性评价研究，尤其是以电力辅助服务市场为背景，对不同调节特性电采暖负荷的经济性分析还鲜有报道。由此，以集中蓄热式电采暖、直热式电采暖和分布式电采暖三种典型电采暖负荷为研究对象，利用时序生产模拟方法，构建基于实时调峰辅助服务的电采暖负荷消纳弃风经济评估模型，以北方地区实际运行的电采暖项目数据为算例，对比几类典型采暖负荷消纳弃风的经济性，并分析了辅助服务价格、弃风水平和采暖负荷运行特性等关键因素对经济性的影响。计算结果显示，与传统火电机组相比，集中蓄热式电采暖和分布式电采暖的可行辅助服务价格在315～460 元/MWh，具有一定的竞争力。

Based on Landsat satellite data, the band ratio method was used to obtain the water area of South Lake in Wuhan City from 2000 to 2021, and the spatiotemporal changes of the water area of South Lake were analyzed. The results showed that in 2003, South Lake had its largest water area, with a decrease in water area during 2000-2007, an increase during 2008-2012, and another decrease during 2013-2021. The timing of South Lake’s management coincides with the period of increased water area, indicating the effectiveness of lake management. Overall, the water area of South Lake decreased from 2000 to 2021, with a total reduction of 1. 02 km² . The most significant reductions occurred on the northern and eastern sides, and there was a rapid and abrupt decrease in South Lake’s area during 2004-2005. South Lake’s water area changes exhibit a positive correlation with evaporation, and a negative correlation with temperature. Both the exponential smoothing model and the long short-term memory (LSTM) neural network model could predict South Lake’s surface area. The water area was projected to increase from 2022 to 2024. However, the predictions from the exponential smoothing model were more accurate. [ABSTRACT FROM AUTHOR]

Outstanding teachers' training has always been given priorities in educational policies and regional teachers' education, but few studies have discussed the features of learning experience of outstanding teachers from a micro perspective. This research, based on the case study on ten outstanding teachers' learning experience, has adopted the cross-case analysis method to have analytical induction to gain the features of outstanding teachers' learning experience from the perspective of " environment-process-outcome" (EPO) evaluation framework. Here are some findings: outstanding teachers can experience highly challenging tasks and positive organizational atmosphere in the learning environment, they have high-level intrinsic motivation and strong will, their learning interaction is featured in active input of individuals and learning content is diversified and differentiated, and their learning outcome tends to point at internal professional achievement and sense of value. Suggestions are given as follows for the designers of outstanding teachers' learning and policy makers of teachers' continuing education: teachers' learning environment should highlight the features of working place and challenging tasks; teachers' learning process should strengthen the design of learning interaction; and teachers' learning outcome should go beyond the narrow-minded view of knowledge learning or competence cultivation.

Objective: To investigate the characteristics of voice-personality perception in blind persons and its relationship with their self-evaluation of personality. Methods: A total of 68 blind persons and 68 sighted peers were respectively recruited to rated 30 short voice recordings on traits of voice-personality perception (including maturity, sunshine, cuteness, indolence, seriousness, simpleness and honestness, gentleness, kindness, self-confidence and optimism). Meanwhile, data on self-evaluations of the above participants and speakers in those recordings, along with acquaintance's ratings on speakers' personality were collected. Results: The research found that compared to sighted peers, blind individuals had a lower voice-personality rating on speakers in traits of sunshine, seriousness, gentleness, kindness, self-confidence and optimism (Ps <0.005). It also detected that the voice-personality ratings on these speakers by blind individuals had a greater deviation from the rating by these speakers/ acquaintances in sunshine; gentleness; kindness and optimism (Ps <0.005). Meanwhile, blind individuals had lower self-rating on personality in sunshine and optimism (Ps <0.005). Furthermore, self-ratings of sunshine from blind individuals were positively associated with their voice-personality ratings of optimism on speakers (r = 0. 28, P<0.05), and their self-ratings of optimism were positively related to their voice-personality ratings of sunshine and self-confidence on speakers (r = 0.27, 0. 28, Ps < 0.05). Conclusion: The study shows that blind individuals have lower voice-personality ratings on others than their sighted peers, which might be due to some of their more negative personality characteristics.

Accurately predicting changes in the infiltration line is crucial for the stability and safety of tailings dams. To fully leverage the spatial features and temporal information provided by infiltration line data, this paper proposes a combined approach using one-dimensional convolutional neural network (1DCNN) and long short-term memory neural network (LSTM) for infiltration line prediction. Taking the main dam of the Qidashan Fengshuigou tailings storage facility in Liaoning Province, China, as an example, the model utilizes six major factors, including historical infiltration lines, reservoir water level, internal and external displacements of the dam, dry beach length, and rainfall, as input data to predict the infiltration line positions for the next 1 day and 3 days. The 1DCNN-LSTM model is compared with classical LSTM and backpropagation neural network (BP) models. The results indicate that the Pearson correlation coefficients (R) for the 1DCNN-LSTM infiltration line predictions are consistently above 0.9. For the next 1 day, the mean absolute error of infiltration line prediction is 0.002 meters, with a maximum absolute error of 0.08 meters. For the next 3 days, the mean absolute error is 0.003 meters, and the maximum absolute error is 0.068 meters. These results demonstrate the superiority of the 1DCNN-LSTM model over classical models, providing a reliable reference for short-term infiltration line predictions. [ABSTRACT FROM AUTHOR]

A full-Newton step feasible interior-point method was proposed to solve the monotone weighted linear complementarity problem (WLCP). Based on continuously differentiable function for linear optimization, new equivalent form of the central equation was given. Then Newton's method was applied to the equivalent system of equations defining the central path, which leads to new search direction for the monotone WLCP. Full-Newton steps are used along this search direction, and hence no line search was required. By appropriately selecting parameters, the strict feasibility of the full-Newton step was analyzed. It was proved that the algorithm was quadratically convergent and has polynomial time iteration complexity. Some numerical results showed that the algorithm was effective. [ABSTRACT FROM AUTHOR]
