Abstract ( 74 )
The muon anomalous magnetic moment aμ=(gμ-2)/2 is a fundamental property of the muon particle, which plays a foundation role in the formation of the Standard Model. The first results of the Fermilab Muon g-2 experiment show that the experimental measurement of aμ deviates with the theoretical prediction by 3.3 standard deviation, as in agreement with the previous measurements from the BNL experiment. The combined result of the two experiments is 4.2 standard deviation away from the Standard Model prediction, which provides a strong evidence for new physics, indicating the existence of possible unknown particles or new forces.

Abstract ( 134 )
The optimization of the territorial spatial pattern is a vital task. The territorial spatial planning and control plays an important supporting role in realizing the "dual carbon" goal. Based on the optimization of the territorial spatial development and protection pattern, this paper discusses the theoretical transformation, the key ways and corresponding "carbon neutralization" management strategies of the territorial spatial planning and control under the "dual carbon" goal, to help the implementation of the "dual carbon" goals. It is shown that the key points of the territorial spatial pattern optimization and the planning response to adapt to the "dual carbon" goal in the future include:constructing the "dual carbon" responsibility regional division system based on the main functional area, exploring the theoretical system for the carbon emission reduction and the carbon sink increase from "air" to "land", and studying the key planning technical ways to help the fine management of the "carbon neutralization".

Abstract ( 107 )
In the context of the goal of the carbon peak and the carbon neutrality, this paper analyzes the challenges of the territorial spatial planning in the carbon technology system integration, the quantitative evaluation of the carbon benefits, the effective implementation of the carbon targets, and proposes the requirements of the adaptation transformation in five aspects:the planning target, the planning scale, the planning vision, the planning technology and the planning countermeasures, based on the analysis of the urban low-carbon development direction and the connotation of the ‘dual carbon’ goals. Combined with the characteristics of the territorial spatial planning in the new era, the response path of the territorial spatial planning under the goal of the carbon peak and the carbon neutrality is explored from four dimensions:the resource footprint accounting, the overall planning of the whole space, the multi-level effective transmission, and the full-cycle systematic supervision, focusing on the spatial structure optimization and the spatial governance.

Abstract ( 90 )
The digital technology in the urban field provides a dynamic data information platform for the accurate acquisition and analysis of the spatial carbon source and sink data. The platform can improve the efficiency of all-factor control of the territorial spatial planning and promote the carbon emission reduction in the urban domain. By integrating the advantages of the multi-discipline, the multi-scale and the multi-probability, the digital technology can make full use of various models and sensors to update and run the data of each system anytime. The trajectory data mining in the digital technology of the urban spatial carbon emission is the development direction that needs attention, while the spatio-temporal trajectory mining of the urban carbon emission should focus on the system update, the spatial surface domain feature mining and the big data application. Based on the digital analysis method, it is found that the ecological vulnerability identification and the security pattern construction are the aspects that need to be focused on to establish the ecologically resilient urban space. Using the remote sensing technology to measure the carbon sinks of the same category will have errors due to different geographical features, and this difficulty deserves attention. The accurate measurement of the urban spatial carbon sinks in the future needs to be realized by combining macro and microscopic features and combining multi-platform and multi-temporal dynamic monitoring.

Abstract ( 85 )
In the background of the "dual carbon" policy, to further clarify the summer thermal environment characteristics of the waterfront settlement in the cold areas of China, the Landsat-8 remote sensing images and the impact factors of 91 typical waterfront settlements in Tianjin, along with the correlation analysis and the multiple linear regression method are used to obtain the characteristics of the thermal environment. It is shown that the thermal environment regulation effect of the planar water is better than that of the linear water, with the difference of the UHI effect up to 1.57℃. The UHI effect has a significant positive correlation with the building density (BD) and the waterfront distance (WD), and is significantly negatively correlated with the average building height (H), the normalized difference vegetation index (NDVI), and the water surface ratio within a radius of 1 km (WR), with the NDVI and the WR having the highest influence weight. There are differences in the influencing factors of the UHI effect in the settlement with different building layouts. The lattice-type settlement has the lowest UHI effect, and the enclosed-type settlement has the highest UHI effect. When the BD is less than 19.08%, the thermal environment can be adjusted well by reducing the WD and increasing the WR. Finally, recommendations for the thermal environment improvement of the waterfront settlements in cold regions are made.

Abstract ( 173 )
Against the backdrop of the severe global climate change, it is a consensus to achieve the goal of the carbon peaking and the carbon neutrality for the climate change mitigation. At the same time, building resilient cities is a new concept and a new way to adapt to the climate change. This paper reviews the studies of the low-carbon resilient cities in response to the climate change, focusing on the practical experience of the climate change mitigation and adaptation in Boston, the United States, Copenhagen, Denmark and Vancouver, Canada, including how to address the climate change through planning. The concept of the low-carbon resilience is proposed to be incorporated into China's territorial spatial planning system to provide a planning support for the realization of the dual-carbon goal and the resilience construction.

Abstract ( 109 )
With the transformation from the traditional document-based systems engineering (DBSE) to the model-based systems engineering (MBSE), it becomes more and more difficult for the "Vee" process model of the DBSE to reflect the characteristics and the requirements of the system of systems (SoS) engineering. Based on the analysis of the SoS engineering (SoSE) process models and their shortcomings, this paper takes the capability as the invariant feature in the system requirement analysis, the design, the verification and the evaluation. The architecture with its prototype is selected as the connector of all activities of the SoSE. A ring model for the SoSE process is proposed and analyzed from the viewpoints of the time, the capability and the architecture. The results of this paper could be used for understanding the SoSE process, establishing the architecturecentric SoSE theory and guiding the SoSE practice.

Abstract ( 146 )
To actively respond to the challenges of the population aging in China, this paper introduces the concept of the PHM model, along with the theoretical support for achieving the "proactive health" instead of the "passive health". The Proactive Health Management (PHM) model is a person-oriented model, which emphasizes one's "own-responsibility" for one's health, in the context of the whole population's engagement and benefit. This paper analyzes the historical development of the health management in China and proposes five dimensions of the PHM concept, including improving the public awareness of the health management, accurately predicting the health risks, intelligently warning for the health crises at an early age, and developing effective interventions, improving health outcomes for all. This paper explores the supporting conditions and technology systems applied in this PHM model based on these five dimensions. Specifically, this paper suggests to conceptualize the PHM, to promote the PHM community at the policy level, and to utilize the information technology, the artificial intelligence, and the behavioral health intervention in the health field. The existing challenges of applying the PHM in practice are reviewed, along with the potential future directions to develop the PHM model in China, particularly, in the health management, the data ecology, the artificial intelligence, the community practice, and the evidence-based medicine. The PHM focuses on the whole population's engagement to ensure that the Chinese population benefits from this model. This study proposes a PHM model as a "five dimension-in-one-place" model that integrates with the informatics and bionomics technologies, putting one's health information in a life circle.

Abstract ( 92 )
Like the Facebook, the Twitter and the TikTok, the WeChat is a well-known mobile instant messaging product with over 1 billion active accounts, and it supports text messages, voices, videos, pictures and payments. The Ministry of Science and Technology of the People's Republic of China makes the science and technology management through various social media, including the WeChat, and the "Rui Ke Ji(Sharp S&T)" is the official WeChat account of the Ministry of Science and Technology, providing information for scientists and technicians. Unlike the editing of the traditional science and technology newspapers and periodicals, the WeChat official account "Rui Ke Ji" has its own characteristics in the manuscript selection and publication (push). In order to see the coverage of the topics of the WeChat articles changing over the time and the relationship between the topics of the articles and the view accounts, a Bias probability topic model, AToT, is used to quantitatively analyze and mine the contents of the articles in the "Rui Ke Ji" and its sub account the "Rui dong yuan(Sharp Dynamic Source)" in this paper. The results reveal where the ministry's publicity lies and how the topics of the articles change over the time. The reading preferences of Chinese scientists and technicians are analyzed and it is shown that there is a certain relationship between the contents of the WeChat articles and the page views. This study helps to improve the editing level of the new media and the science and technology publicity.
