摘要：
In remote sensing, change detection has always been a fundamental yet challenging research topic, with profound theoretical significance and extensive application value. Over the past decades, the emergence and development of deep learning has provided new technical supports for supervised change detection and advanced its accuracy to unprecedented levels. Nevertheless, owing to the strong reliance and weak transferability of pre-labeled references, supervised learning modes still require some degrees of human assistance, which is not applicable to all the change detection tasks. In addition, agnostic to any specific inherent property, changes may display inconstant and irregular characteristics when occurring between different land cover categories, making them incompatible with traditional end-to-end learning formats. In this research, we investigate the utilization of unsupervised deep learning mode, and develop a novel approach, namely content-invariant translation (CIT), for unsupervised change detection in bi-temporal remotely sensed images. In this method, a new framework integrating the adversarial learning algorithm and hybrid attention mechanism is designed to learn a one-sided cross-domain translation from the pre-event domain to the post-event one. During this process, a self-attention module focuses on small-scale image patches and ensures the content consistency of each pair of pre-event and translated patches, and meanwhile, a cross-domain module focuses on large-scale images and guarantees the style similarity of two groups of translated and post-event patches. After translation, the style discrepancies in bi-temporal images are suppressed while the real content changes are highlighted. Extensive experiments conducted on three typical datasets that with diverse types of changes verify the effectiveness and competitiveness of our newly proposed CIT by a large margin.

摘要：
Wuhan hot-dry noodles, as one of the traditional Chinese snacks, have been famous in most parts of China for nearly 100 years. Its characteristic, taste, and quick cooking method cater to the needs of many people. However, food safety has become an essential obstacle in developing Wuhan hot-dry noodles. The present work developed evaluation indicators, and selected an entropy method to analyse the food safety problems of Wuhan hot-dry noodles based on the system safety theory. Results showed that the score was 2.59 over 5.00, which meant the performance was below average. This could have been due to poor perception of employees on food safety, primary enterprise management, and less effective and authoritative standards within the industry. Based on the system theory, the present work suggested engineering, education, and enforcement, namely the "3E principle", to solve the above problems. The key to the "3E principle" is to focus on identifying, controlling, and evaluating hazards around the most critical issues, and solving them in order of importance and urgency. The "3E principle" also emphasises circular processing for better food safety. (c) All Rights Reserved

摘要：
After the pandemic, China's fiscal and monetary authorities implemented macroeco-nomic restructuring measures to combat the pandemic. Using a difference-in-difference model based on data collected during the COVID-19 phase, this study attempted to determine the economic recovery in China using the pandemic means for economic growth and energy consumption in other economies. A 0.21 percent increase in the western region's economic growth is comparable to a 0.15 percent increase in the growth of the southern central and northern regions during the pandemic period. Accordingly, we found evidence of actual provincial spillover effects in the clustering of high-and poor-performing regions. The impact of China's economic resurgence beyond the pandemic phase plays an important role in expanding power consumption in different regions. Since headwinds hamper economic development to aggregate output, fiscal policy is the sole option for maintaining pollution levels while simultaneously improving household well-being in terms of demand and employment.(c) 2022 Economic Society of Australia, Queensland.

摘要：
Under Metaverse, security management of communication networks in digital cultural consumption has attracted more and more attention. As we know, security risks of communication networks caused by non-human factors are becoming weaker and weaker due to technology optimization. Meanwhile, play-ers play significant and increasing role in communication networks. Taking mobile games as an example, this paper designed and applied the security management model to improve security management of communication networks in digital cultural consumption under Metaverse. The results show that: (1) The physiological, psychological, pathological, pharmacological, physical and psychosocial factors exert tremendous influence on communication networks. The psychosocial factors are more prominent. (2) There is security threshold in communication networks. It means that the security state can be entered if security threshold is crossed. This paper designs security threshold as the III level (5.5 <= P < 6.5). (3) This paper proposes 3E rules (That is, engineering, education, enforcement). It is beneficial to deal with security risks in communication networks. (4) After two security evaluations, the result is G2 = 6.70 > G 1 = 5.01. This confirms the effectiveness of the security management model.(c) 2023 Published by Elsevier B.V. on behalf of Faculty of Computers and Information, Cairo University.

摘要：
The COVID-19 pandemic, with its risk of repeated fluctuations, has shifted the basis for decisions on tourism spending. Thus, it is crucial for the hospitality industry to understand the factors that influence accommodation consumption. Grounded in signaling theory, our empirical analysis is based on analyzing data from eLong on 7209 Chinese hotels using binary logistic regression and the ordinary least squares method (OLS). The main findings are as follows: (1) completeness of information, online hygiene rating and hygiene recommendation tags have a significant impact on hotel consumption; (2) online hygiene rating has a positively significant moderating effect on the relationship between information completeness and hotel sales; and (3) there is variability in the factors that influence the generation and growth of hotel sales. In addition, we discuss the role of online travel agencies (OTAs) and provide relevant advice for practitioners.

摘要：
The intense development of urban–rural integration has brought about a constant increase in people’s demand for public culture. In particular, as the equalization of public cultural services is promoted, narrowing the gap between the services offered in urban and rural settings has gradually become the dominant orientation to promote urban–rural integration and enhance the rights and interests of the people. Starting from the principles of the new public service, this research conducted field interviews in Xuling Town, Anhui Province, China. The Zaltman metaphor elicitation technique (ZMET) was used to analyze the interview content, and five inferences about the construction of township public culture were drawn: (1) cultural facilities have a significant impact on township public cultural construction; (2) the role of cultural talents is essential but lack of talent is normal in townships; (3) carrying out cultural activities is the top priority of township public cultural construction; (4) cultural management is an indispensable auxiliary link but the management level is insufficient; (5) and the cultural activities of traditional festivals are particularly important. Moreover, on the basis of these five inferences, the fuzzy-set qualitative comparative analysis (fsQCA) method was used to analyze the survey data and verify the underlying problems around public cultural service effectiveness as well as resource allocation in township areas. Finally, countermeasures are proposed on how to narrow the gap, which are of reference significance for improving the quality of township public cultural services in the context of urban–rural integration and meeting the cultural needs of residents.

摘要：
In this study, we investigate the urban landscape patterns in Wuhan, China based on the land use data in the vector format. Using the approach of landscape metric analysis, we calculate forty-four vector-based landscape metrics and then reduce redundant ones through a combination of Spearman correlation analysis and factor analysis, in order to extract a core set of characterizing landscape metrics. We find that the urban landscape can be depicted by six factors including the overall shape and diversity, mean proximity, overall area variation, fragmentation variation, elongation variation, and mean shape complexity. After analyzing typical patterns indicated by the core metrics and the spatial distribution of land use patterns, we compare our findings with other studies and discuss how the core metrics coincide and differ.

摘要：
Roads are closely related to people’s lives, and road network extraction has become one of the most important remote sensing tasks. This study aimed to propose a road extraction network with an embedded attention mechanism to solve the problem of automatic extraction of road networks from a large number of remote sensing images. Channel attention mechanism and spatial attention mechanism were introduced to enhance the use of spectral information and spatial information based on the U-Net framework. Moreover, residual densely connected blocks were introduced to enhance feature reuse and information flow transfer, and a residual dilated convolution module was introduced to extract road network information at different scales. The experimental results showed that the method proposed in this study outperformed the compared algorithms in overall accuracy. This method had fewer false detections, and the extracted roads were closer to ground truth. Ablation experiments showed that the proposed modules could effectively improve road extraction accuracy.

摘要：
In cold chain logistics, fresh agricultural products are susceptible to deteriorate due to the passage of time in the distribution process. To reduce the loss of cargo, this research integrates the traditional refrigeration cost into the freshness-keeping cost invested in the process of transportation and unloading goods. We rely on the investment of freshness-keeping cost to reduce the cargo damage cost caused by the distribution process and then propose a new vehicle routing problem (VRP). According to all relevant costs, this research builds a mathematical model with the goal of minimizing the total distribution cost. A hybrid ant colony optimization is designed to solve the problem, and the effectiveness of the model and algorithm are verified through two sets of comparative experiments. To determine which products should be invested in freshness-keeping cost to reduce the total distribution cost, we perform numerical analysis on the relevant parameters in the model. Results provide decision-making references for cold chain logistics distribution enterprises in the design of distribution routes.

摘要：
Geometric-semantic coherent building models are demanding in many geoscience applications. Conventional building modeling methods often rely on successive roof plane segmentation and fitting. The subsequent reconstruction procedure is difficult to assure topologic consistency and geometric accuracy. This article starts with a library of predefined building models or primitives, including pyramid, gable, hip, etc. We propose an optimal model fitting approach that holistically determines all of its parameters from segmented point cloud data. The approach is formulated as an optimization problem that minimizes the point-to-mesh distance between the point cloud and the meshed primitive model. Necessary constraints in the form of inequality equations are introduced to assure correct and reliable solution. For complex roofs consisting of several predefined primitive models, a hierarchical procedure is presented to reconstruct the major roof model and its superstructures sequentially. The CityGML LoD2 model is created from the parameterized primitives. The quality and performance of this approach are evaluated with airborne lidar and photogrammetric point clouds. Based on the experiments with 910 buildings, the primitive fitting accuracy is 7.8 cm and the corner uncertainty is 0.36 m or 0.78 times the ground point spacing; the building boundary consistency is 89.6%. The study demonstrates a piecewise continuous polyhedral building model can be determined through a holistic parameter optimization process. The resultant building models intrinsically best fit to the input point cloud with topologic integrity. The approach not only qualitatively generates semantic building models but also exhibits the potential for building reconstruction over large areas.

摘要：
Although synthetic aperture radar (SAR) sensors function well at all times and under all weather conditions, the images they produce are not intuitively straightforward. A novel idea based on data fusion is introduced to translate SAR data into optical image in this paper. The proposed SAR-optical image translation is implemented using an intensity–hue–saturation (IHS) and wavelet transform integrated fusion (IHSW), so as to preserve as much as spatial details from SAR data, and minimize the spectral distortion of translated output. COSMO-SkyMed and ENVISAT-ASAR images are translated into optical images with the fusion of Landsat TM images, and the fusion results are compared with some conventional fusion methods, as well as the texture synthesis approach. Quality assessment of different fused outputs is carried out by using six quality indices. Visual and statistical comparisons of the final results indicate that the proposed approach achieves an effective translation from SAR to optical image and is superior to texture synthesis-based algorithm in terms of preserving spatial and spectral information. The proposed translation technique presents an alternative to improve the interpretability of SAR images.

摘要：
The availability of very high spatial resolution (VHR) remote sensing imagery provides unique opportunities to exploit meaningful change information in detail with object-oriented image analysis. This study investigated land cover (LC) changes in Shahu Lake of Wuhan using multi-temporal VHR aerial images in the years 1978, 1981, 1989, 1995, 2003, and 2011. A multi-resolution segmentation algorithm and CART (classification and regression trees) classifier were employed to perform highly accurate LC classification of the individual images, while a post-classification comparison method was used to detect changes. The experiments demonstrated that significant changes in LC occurred along with the rapid urbanization during 1978–2011. The dominant changes that took place in the study area were lake and vegetation shrinking, replaced by high density buildings and roads. The total area of Shahu Lake decreased from ~7.64 km<sup>2</sup>to ~3.60 km<sup>2</sup>during the past 33 years, where 52.91% of its original area was lost. The presented results also indicated that urban expansion and inadequate legislative protection are the main factors in Shahu Lake's shrinking. The object-oriented change detection schema presented in this manuscript enables us to better understand the specific spatial changes of Shahu Lake, which can be used to make reasonable decisions for lake protection and urban development.<br/> 2018 by the authors.
