The article uses CNKI and Google Scholar as the main document search methods. Through induction and analysis, it can be found that the call for urban renewal in Zhuhai has been sounded at this stage. The ancient villages in different areas of the city, such as Tangjiahuitong Village, Doumen Nanmen Village, and Nanping Beishan Village, have been given a certain degree by related scholars. For in-depth research, many journals and master and doctoral papers already have relevant documents available for retrieval. Through the analysis of relevant literature, we can see that the research method is a combination of quantitative and qualitative analysis, and some new results have been obtained through the analysis. In recent years, Qianshan Cuiwei Village also has some related literature studies, but there are few literatures. The literature is mainly It is a qualitative analysis and research, and there is no quantitative analysis. In the future, relevant scholars can start with quantitative analysis, and space syntax may be a good method. In the feasibility study of Cuiwei Village using this method, it was found that the spatial syntax has certain limitations at the geographic scale. Therefore, how to apply the spatial syntax scientifically, rationally and effectively in the village research is a question worthy of discussion in the future.

The policy of "bus priority" solves the problem of urban residents' travel and is an important part of urban construction. This paper analyzes the research progress and implementation of "bus priority" at the current stage in China and the problems existing in the current situation of urban trans-portation in the practice of "bus priority" in Macau through literature analysis. The results show that although large cities in China have better implemented the "bus priority" policy, there are large differences among cities, the coverage is small, most small cities have less literature, and the in-vestment in research and construction is insufficient. At this stage, people pay more attention to the punctuality, convenience, benefit and convenience of public transport. The author provides some feasible reference suggestions for the future development environment, infrastructure construction, social value and economic level of "bus priority" in Macau.

Although people can walk out of Cuiwei village, they are always in a confused state, and it is difficult to grasp the spatial form of the whole area. Taking Cuiwei village in Qianshan, Zhuhai as an example, based on the theory of spatial syntax, this paper analyzes the integration degree of ancient village vision and the spatial characteristics of historical location, the understandability degree and integration degree of village vision, the control value of vision and the spatial characteristics of historical location, and puts forward relevant suggestions for the future renewal of villages.

This study takes Cuiwei village, located in Qianshan District of Zhuhai City, as an example. First, it analyzes the human flow activities and activity size of village road a, the visual agglomeration degree and the spatial characteristics of historical sections. Secondly, select the most representative traditional buildings in the village, namely Sanwang temple and Wechsler mansion. When r=n and radius r=3, observe the changes of two parameters of visual integration and visual depth of the two historical buildings. And with the help of Baidu time machine photos of different periods to observe and record the changes of stores and human behavior characteristics. The results show that at this stage, the coordination of villages is poor, people's recognition in the village space is weak, people can't use local perception to reflect the overall space, there is an obvious interface between the inside and outside of the village, the isolation state is obvious, the local intelligibility is good, but the global intelligibility is poor.

With the continuous construction of urbanization, climate change, crowd concentration, disasters and risks and other factors have led to the continuous exposure of urban vulnerability, so the issue of urban safety and urban resilience has become an unavoidable issue in urban planning and construction in today's society. Zhuhai, located in the southwest of the Pearl River Delta, is an important node city in the Guangdong-Hong Kong-Macao Greater Bay Area, and in recent years, the flood disasters caused by extreme climate have adversely affected Zhuhai's economic development and social level. Based on the concept and meaning of resilient city, this study summarizes the relevant experience of resilient cities in China, analyzes the difference between disaster prevention planning and traditional planning from the perspective of resilient city planning, technical means and ideas, and studies on the governance of the current planning status of resilient cities in China, and discusses the resilience assessment of urban disasters in Zhuhai under the support of the resilient city theory based on the Zhuhai sponge city drainage special planning project, and from the urban disaster prevention and mitigation policies and disaster relief. The three aspects of climate adaptation planning technology and the construction of Zhuhai Community Disaster Prevention Park put forward corresponding countermeasures conducive to zhuhai's economic development and people's living standards improvement, enhance urban resilience, and at the same time adopt regional innovation methods, learn from the relevant treatment methods and methods of disaster prevention and mitigation and relief planning under the concept of Shenzhen Resilient City, and provide reference value for Zhuhai's resilient urban planning research and even for the resilience development of typical coastal cities.

With the rapid development of science and technology, since the reform and opening up, the speed of urbanization construction has been accelerating. Zhuhai City has steadily promoted the transformation of old factories, old towns and old villages, which in turn promoted the process of urban renewal and realized the economic development of the city. Take off, promote the transformation and upgrading of industries, and improve people's living standards. This study takes the former Shancuiwei Historic District as an example, and gives corresponding policy suggestions for village renovation and renewal and future development.

With the rapid development of China's economy, the urbanization process is gradually accelerating, and there are a large number of traditional village spaces are abandoned and compressed, which has greatly changed the original pattern of ancient villages. Cuiwei village is an example of Zhuhai's typical Lingnan Cantonese traditional village evolving into a village in the city, which has experienced many changes in spatial pattern. This paper adopts the method of qualitative investigation to conduct a detailed investigation and analysis of the types of historical buildings in Cuiwei village, and focuses on the impact of historical buildings on people's spatial feelings. It puts forward planning suggestions to provide reference for the follow-up protection of the architectural heritage of Cantonese traditional villages.

The climate of Lingnan determines the form of the building. As a well-preserved representative building in the world cultural heritage of Macau with the characteristics of Lingnan architectural style, the Mandarin’s House reflects the architectural design of the subtropical zone and the humid and hot climate of Macau, which is worthy of later analysis, study and research application.

In Macau, China, there are still many traditional buildings built at the end of the 19th century. Among the traditional residential buildings with Lingnan style, the Mandarin’s House is the largest, covering an area of 4,000 square meters. It consists of a number of buildings of different styles and open spaces. There are more than 60 large and small rooms. It is a rare family-style building complex in Macau. The building has a depth of more than 120 meters along the direction of Rua da Barra. The gate building, the servant room building and the two juxtaposed courtyard buildings behind the main gate building are arranged in sequence. In the 1950s and 1960s, the descendants of the Zheng family lived in different places and developed independently. Many spaces in the Mandarin’s House were sub-leased, and at one time more than 300 people lived in it. The scene of "Seventy-two Tenants" appears. It is precisely because there are so many families and tenants living there that the size of the space, the architectural components and the details of the decoration can all reflect the hierarchical system still retained in the late Qing Dynasty.

Hepatocellular carcinoma (HCC) is an aggressive malignancy. Previous studies have found that lamin B1 (LMNB1) contributes to the development of human cancers. However, the biological functions and prognostic values of LMNB1 in HCC have not been adequately elucidated. In our present research, the expression pattern of LMNB1 was analyzed. The prognostic values of LMNB1 were evaluated by Kaplan-Meier survival analysis and Cox proportional hazards regression analysis. The effects of LMNB1 on HCC progression were assessed by Cell Counting Kit-8 (CCK-8), colony formation, wound healing, Transwell and in vivo xenograft assays. The mechanisms of LMNB1 in HCC progression were elucidated by gene set enrichment analysis (GSEA) and loss-of-function assays. Besides, a nomogram for predicting overall survival (OS) was constructed. The results demonstrated that LMNB1 was overexpressed in HCC and that increased LMNB1 expression predicted a dismal prognosis. Further experiments showed that LMNB1 facilitated cell proliferation and metastasis in HCC. Functional enrichment analysis revealed that LMNB1 modulated metastasis-associated biological functions such as focal adhesion, extracellular matrix, cell junctions and cell adhesion. Mechanistically, we revealed that LMNB1 promoted HCC progression by regulating the phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) pathways. Moreover, incorporating LMNB1, Ki67 and Barcelona Clinic Liver Cancer (BCLC) stage into a nomogram showed better predictive accuracy than the Tumor-Node-Metastasis (TNM) stage and BCLC stage. In conclusion, LMNB1 may serve as an effective therapeutic target as well as a reliable prognostic biomarker for HCC.

Since the reform and opening up, the city has steadily promoted the renovation of old maternity houses, towns and villages in response to the call of the state, thus promoting urban renewal, realizing urban economic development, industrial upgrading and people's livelihood improvement. The living density of economic housing is high, and the quality needs to be further optimized. However, the current urban renewal needs to improve the living quality of housing to serve the people. Therefore, when planning, constructing and renovating the interior space of public housing and meeting people's basic living conditions, people's intuitive feeling of the environment should be put first, rather than excessive attention to formal beauty—taking the EDF. de Alameda da Tranquilidade in Macau, as an example, based on the theory of space syntax, this paper conducts a convex space analysis and research on the interior space form of the first building of EDF. de Alameda da Tranqui-lidade, including the global integration degree, local integration degree (R=3,6), connectivity, intelligibility, control and Mean Depth, analyze the areas with higher integration, connection value and control value and lower areas, and make suggestions for future plane optimization, related The recommendations also apply to the second and third buildings of Yongning Plaza Building, providing better reference value and reference for relevant government departments.

Chinese cities have a history of at least five thousand years, and the city of Chang'an in the Tang Dynasty is a milestone. The planning and design of Chang'an City represented the most advanced level in the world at that time and laid the foundation for the design of China's capital city. With the global outbreak of the new crown virus COVID-19, it is even more necessary to enter the "post-epidemic era" for urban epidemic prevention and governance measures. In the history of the Tang Dynasty, there were 49 plague outbreaks, but they still created prosperous situations such as the "Excellent Governance during the Zhenguan Times" and " Flourishment Age of Kaiyuan Era". Based on the historical data and documentary interviews and analysis of the textual research, this article summarizes the urban epidemic prevention and management of the Tang Chang’an city from six aspects, including the site selection, water supply and drainage system, medical isolation facilities, lifang management system, landscaping and mainstream medical ideological guidance system, and summarize the advanced experience of typical capitals in ancient China to provide a reference for modern urban epidemic prevention and governance.

Space syntax is one of the important methods of city analysis and calculation. Based on the theory of space syntax, this research takes two important commercial and financial buildings of Bank of China Tower and Edificio Comercial Si Toi in Macau as examples to analyze their internal spatial structure and import Depthmap for calculation. Combining with related topological calculation methods, by analyzing the topological values of the overall integration degree, local integration degree, global depth and selectivity of the space, quantitatively explore the structure of the space, understand the relationship between the overall space and local space of commercial buildings, and discover the spatial structure And proposed corresponding optimization strategies to provide a reference for the future reconstruction of the typical commercial building space in Macau from the 1980s to the 1990s.

Space syntax is one of the important methods for urban analysis and calculation. Based on the theory of space syntax, this study takes the Macau Conservatory of Music, an important Portuguese historical building, as an example, to first analyze the particularity of its development history in urban heritage, followed by the internal spatial structure, and import Depthmap for operation, combined with topology-related calculation methods. By analyzing the topological values such as the overall integration, local integration, global depth and selectivity of the space, we can quantitatively explore the structure of the space, understand the relationship between the overall space and the local space of the Macau Conservatory of Music, discover the deficiencies in the space structure, and propose corresponding optimization strategies are proposed to provide ideas and reference for the future renovation of the typical performing arts architectural space in the urban heritage of Macau.

This research takes Cuiwei Village located in Qianshan District of Zhuhai City as an example. The village is investigated and analyzed through field research, and the street scale, spatial structure, functional characteristics of streets, internal commercial distribution forms, and functions in the Cuiwei Historic Block are studied and analyzed. Based on the convex space analysis method and the line of sight analysis method in the space syntax theory, with the help of the Depthmap software, the complex street nodes, that is, the space of the two nodes A and B analyzed. Through the establishment of a viewshed model, including the analysis of the viewport integration degree, the viewport agglomeration degree, the viewport connection value and the spatial characteristics of the historical area, the most representative traditional buildings in the village, namely the Sanwang Temple and the Weishi Mansion, are selected. =N and when the radius R=3, observe the changes of the two parameters, the integration of the visual field and the visual depth of the two historical buildings. And with the help of Baidu time machine photos in different periods to observe and record the store's changes and people's behavioural characteristics. The results show that: at the present stage, the coordination of villages is poor, people's recognition in the village space is weak, and people cannot use local perception to reflect the overall space. There are obvious sub-interfaces between the interior of the village and the outside world—good but poor global intelligibility. After an on-the-spot investigation and analysis, it can be seen that although people can walk out of Cuiwei Village, they are always in a state of confusion, and it is difficult to grasp the spatial form of the overall area. Therefore, the space syntax analysis results are consistent with the field survey results, so this research method has good reference value and reference significance in the study of village space.

As the urbanization process in developing countries continues to accelerate, although my country has achieved significant results in planning and construction, there are still many problems. For example, the rate of urban green space decreases with the continuous increase of urban buildings. Therefore, the domestic urban underground civil air defence Engineering construction is in a very important position at this stage, and our development goals must be shifted from above ground to underground. This article analyzes the general situation of the domestic civil air defence engineering system, expounds on the current situation and existing problems of my country's urban civil air defence engineering system, which has an important influence on the development of my country's cities. Functional departments must take into account the various functions of civil air defence projects and put people's safety first. At the same time, firefighters should also improve their professionalism, leadership and organizational skills, and evacuate people when encountering danger and arrange for them to take refuge in designated locations. The technicians in the relevant departments in the city need to use scientific and technological means to mix the urban network system in series and parallel so that the various structures of the urban network system are unified and interact with each other. When a disaster strikes, it can protect the safety of the people and reduce the economic loss of the city. Reduce to the lowest level to maximize benefits.

A turbulent medium with eddies of different scales gives rise to fluctuations in the index of refraction during the process of wave propagation, which interferes with the original spatial relationship, phase relationship and optical path. The outputs of two-dimensional imaging systems suffer from anamorphosis brought about by this effect. Randomness, along with multiple types of degradation, make it a challenging task to analyse the reciprocal physical process. Here, we present a generative adversarial network (TSR-WGAN), which integrates temporal and spatial information embedded in the three-dimensional input to learn the representation of the residual between the observed and latent ideal data. Vision-friendly and credible sequences are produced without extra assumptions on the scale and strength of turbulence. The capability of TSR-WGAN is demonstrated through tests on our dataset, which contains 27,458 sequences with 411,870 frames of algorithm simulated data, physical simulated data and real data. TSR-WGAN exhibits promising visual quality and a deep understanding of the disparity between random perturbations and object movements. These preliminary results also shed light on the potential of deep learning to parse stochastic physical processes from particular perspectives and to solve complicated image reconstruction problems given limited data. Turbulent optical distortions in the atmosphere limit the ability of optical technologies such as laser communication and long-distance environmental monitoring. A new method using adversarial networks learns to counter the physical processes underlying the turbulence so that complex optical scenes can be reconstructed.

Urban village is an important carrier of cultural heritage and a settlement space with regional characteristics. It can organically integrate and fully express the production and life and cultural customs of local residents. Taking Cuiwei historical village as an example, this study reasonably analyzes the problems encountered in the process of industrial development and transformation of historical villages, and provides reference for relevant departments.

The fast and robust detection of far targets is one of the key techniques in infrared searching and tracking applications. Using multiorder directional derivatives, an effective and concise detection method performed on a single IR image is proposed in this article. First, multiorder directional derivatives of an image are derived from the facet model. According to the derivative characteristics of small targets, enhancement filters are designed to maximize the target components. Convolved with these filters, the small targets are enhanced and the backgrounds are suppressed in each derivative subband. The final result is obtained by fusing all these filtered derivative subbands. The experimental results demonstrate that the proposed method consistently achieves a robust and effective performance on all datasets. In addition, the low computational complexity makes the proposed method suitable for real time detection purpose.

Recently, research on thermal infrared human face analysis grows rapidly. However, due to the low contrast and limited information, human face in thermal infrared images is difficult to segment precisely. To overcome these shortcomings of thermal images, we propose an improved circular shortest path method in this paper. In our method, the proposed gradient based cost function enhances the gradient information and extracts detail of the original image. In addition, we propose a shape constraint by using ellipse derivative in the cost function. The constraint helps the contour to conform to the real human face. Moreover, the proposed certainty penalty term and straight path penalty term restrain the effect of the local minima regions and improve the robustness of our method. Our method could effectively extract the precise human face contour and thus segment the complete human face. Experimental results show that our method performs well for thermal infrared face segmentation, in both visual and quantitative ways.

Interest point detection has been widely used in image analysis applications. However, some interest points, including small structures and large angle corners, could not be effectively extracted. This paper proposes a limiting form of median Laplacian of Gaussian (LMLG) filter, which combines the superiority of the traditional Laplacian of Gaussian (LoG) filter and a limiting form of the weighted median LoG filter. A detector is also proposed based on the LMLG filter. The LMLG filter aims to improve the detection of LoG-based methods for interest points, especially small structures and large angle corners. Also, it could detect blobs, edges, and local structures. We conduct the repeatability and discrimination experiments on the Oxford dataset. Moreover, we conduct the recall rate experiment on the DTU dataset. The experiments show that the proposed method achieves comparable performance with state-of-the-art methods. In order to verify the utility of the LMLG detector, we carry out a series of interest point detector-based applications: face recognition, infrared-visible image registration, and image classification. The results demonstrate that the LMLG detector performs better than the nine detectors in face recognition. The LMLG detector outperforms the nine detectors and Hrkać's, Han's and Liu's methods in infrared-visible image registration. Our method also gives a comparable result on image classification. The source code of the proposed LMLG detector is made publicly available at https://github.com/chenjzBUAA/LMLG-detector.

Objective To investigate the prognostic factors of patients with pancreatic neuroendocrine tumor (pNETs) after surgical resection, and to analyze the value of enucleation for pNETs without distant metastasis that are well-differentiated (G1) and have a diameter ≤ 4 cm. Methods Data from pNET patients undergoing surgical resection between 2004 and 2017 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. Kaplan–Meier analysis and log-rank testing were used for the survival comparisons. Adjusted HRs with 95% CIs were calculated using univariate and multivariate Cox regression models to estimate the prognostic factors. P Results This study found that female, cases diagnosed after 2010, and pancreatic body/tail tumors were protective factors for good survival, while histological grade G3, a larger tumor size, distant metastasis, AJCC 8th stage III-IV and age over 60 were independent prognostic factors for a worse OS/CSS. For the pNETs that were well-differentiated (G1) and had a tumor diameter ≤ 4 cm, the type of surgery was an independent factor for the long-term prognosis of this group. Compared with pancreaticoduodenectomy and total pancreatectomy, patients who were accepted enucleation had better OS/CSS. Conclusion For pNETs patients undergoing surgical resection, sex, year of diagnosis, tumor location, pathological grade, tumor size, distant metastasis, race, and age were independent prognostic factors associated with the OS/CSS of patients. For pNETs patients with G1 and a tumor diameter less than 4 cm, if the tumor was located over 3 mm from the pancreatic duct, enucleation may be a wise choice.
