Representations of hypergraph states with neural networks

引用

Communications in Theoretical Physics 2021年第10期73卷 99-108页

作者：杨莹曹怀信 school of Mathematics and Information Technology Yuncheng University school of Mathematics and Statistics Shaanxi Normal University

The quantum many-body problem(QMBP) has become a hot topic in high-energy physics and condensed-matter physics. With an exponential increase in the dimensions of Hilbert space, it becomes very challenging to solve the QMBP, even with the most powerful computers. With the rapid development of machine learning, artificial neural networks provide a powerful tool that can represent or approximate quantum many-body states. In this paper, we aim to explicitly construct the neural network representations of hypergraph states. We construct the neural network representations for any k-uniform hypergraph state and any hypergraph state,respectively, without stochastic optimization of the network parameters. Our method constructively shows that all hypergraph states can be represented precisely by the appropriate neural networks introduced in [Science 355(2017) 602] and formulated in [Sci. ***. Astron. 63(2020) 210312].

本文设计合成了一种Te^(4+)离子掺杂的Cs_(2)InCl_(5)·H_(2)O单晶,该单晶在紫外光激发下发射明亮橙光.未掺杂的Cs_(2)InCl_(5)·H_(2)O单晶几乎没有发光现象,但Te^(4+)掺杂的Cs_(2)InCl_(5)·H_(2)O单晶,发射峰位于660 nm,并伴随着大的Stokes位移和宽的发光半峰宽(180 nm).结合变温荧光光谱以及飞秒瞬态吸收光谱等表征,揭示了其发光机理为自陷激子发光.零维结构中的强电声耦合以及软晶格有利于形成并稳定自陷激子.特别地,由于Te^(4+)离子的最外层电子结构为5s^(2),对温度变化较为灵敏,Te^(4+)离子掺杂的Cs_(2)InCl_(5)·H_(2)O单晶的发光寿命表现出了非常强的温度依赖性,发光寿命从80 K下的6μs缩短至380 K下的19 ns,320 K处的相对灵敏度达到0.062 K^(-1),可以与传统稀土基光学测温材料相媲美.据我们所知,这是首次将铟基金属卤化物钙钛矿单晶应用于光学测温,将为设计合成新型多功能响应的金属卤化物钙钛矿发光材料提供借鉴意义.

Powerful lasers interacting with solid targets can generate intense electromagnetic pulses(EMPs).In this study,EMPs produced by a pulsed laser(1 ps,100 J)shooting at CH targets doped with different titanium(Ti)contents at the XG-III laser facility are measured and *** results demonstrate that the intensity of EMPs first increases with Ti doping content from 1%to 7%and then *** electron spectra show that EMP emission is closely related to the hot electrons ejected from the target surface,which is confirmed by an analysis based on the target–holder–ground equivalent antenna *** conclusions of this study provide a new approach to achieve tunable EMP radiation by adjusting the metal content of solid targets,and will also help in understanding the mechanism ofEMPgeneration and ejection of hot electrons during laser coupling with targets.

Significance of Substrate Selection in the Efficiency of Wastewater Treatment in Constructed Wetlands (CWs)

引用

Journal of Water Resource and Protection 2023年第9期15卷 424-441页

作者： Snezana Didanovic Danijel Vrhovsek Minisry of Ecology Spatial Planning and Urbanism Podgorica Montenegro and Jo&zcaronef Stefan International Postgarduate School Ljubljana Slovenija Jo&zcaron ef Stefan International Postgarduate School Ljubljana Slovenija

Constructed wetlands (CWs) can achieve a high-quality wastewater treatment and a quality that meets the prescribed standard, defined by legislation on wastewater discharge. A limitation in the application of constructed wetlands (CWs) is the large area requirement, which limits their application. The subject matter of this research is to check the possibility of improving the efficiency of wastewater treatment and reducing the required area for constructed wetlands (CWs) by using an adequate substrate under the conditions found in Montenegro. In the described experiment, the constructed wetlands (CW) have a vertical flow system and play the role of a secondary wastewater treatment, receiving water from the existing WWTP in Podgorica after the primary treatment. These vertical flow systems reflect experience with the use of similar systems in Slovenija, Austria and Italy. Measurements to date show that the substrate plays an important role and that wastewater treatment efficacy varies significantly with respect to the type of substrate when used under the conditions available in Montenegro.

基于注意力机制的LSTM时变水声信道深度学习预测（英文）

Journal of Marine Science and Application 2023年第3期 650-658页

作者：朱政亮童峰周跃海张梓峤张福民 National and Local Joint Engineering research Center for Navigation and Location Service Technology Xiamen University College of Ocean and Earth Sciences Xiamen University school of Electrical and Computer Engineering Georgia Institute of Technology Cheng Kar-Shun Robotics Institute Hong Kong University of Science and Technology

This paper investigates the channel prediction algorithm of the time-varying channels in underwater acoustic(UWA) communication systems using the long short-term memory(LSTM) model with the attention mechanism. AttLstmPreNet is a deep learning model that combines an attention mechanism with LSTM-type models to capture temporal information with different scales from historical UWA channels. The attention mechanism is used to capture sparsity in the time-delay scales and coherence in the gep-time scale under the LSTM framework. The soft attention mechanism is introduced before the LSTM to support the model to focus on the features of input sequences and help improve the learning capacity of the proposed model. The performance of the proposed model is validated using different simulation time-varying UWA channels. Compared with the adaptive channel predictors and the plain LSTM model, the proposed model is better in terms of channel prediction accuracy.
