2Blockchain Data Analysis from the Perspective of Complex Networks:Overview显示文摘Cryptocurrency based on blockchain technology has gradually become a choice for people to invest in,and several users have participated in the accumulation of massive transaction data.Complete transaction records in blockchains and the openness of data provide researchers with opportunities to mine and analyze data in blockchains.Network modeling and analysis of cryptocurrency transaction records are common methods in blockchain data analysis.The analysis of attribute graphs can provide insights into various economic indicators,illegal activities,and general Internet security,among others.Accordingly,this article aims to summarize and analyze the literature on cryptocurrency transaction data from the perspective of complex networks.To provide systematic guidance for researchers,we put forward a blockchain data analysis framework based on the introduction of the relevant background and reviewed the work from five aspects:blockchain data model,data acquisition on blockchains,existing analysis tools,available insights,and common analysis methods.For each aspect,we introduce the research problems,summarize the methods,and discuss the results and findings.Finally,we present future research points and several open questions in the study of cryptocurrency transaction networks.Wanshui Song Wenyin Zhang Jiuru Wang Linbo Zhai Pengkun Jiang Shanyun Huang Bei Li 2023Tsinghua Science and Technology2023,28,1:0
3Health Status and Food Intake Frequency of Elderly Residents During COVID-19 Community Closure—Jiangxia District,Wuhan City,China,2020显示文摘What is already known about this topic?Elderly persons are vulnerable to infectious diseases,and nutritional status and health conditions were important to evaluate for disease prevention and ability to recover for the elderly during the coronavirus disease 2019(COVID-19)pandemic.What is added by this report?In our study,a rapid assessment questionnaire was used to investigate the change of household life and dietary intake of the elderly(aged 60 years or more)during community closure.Food consumption frequency of aquatic food products,soybeans,and fresh fruits declined dramatically with reductions of 70.9%,70.9%,and 53.0%,respectively,and 49.6%of the elderly lived with chronic non-communicable diseases but had little knowledge of nutrition and health.What are the implications for public health practice?Community closure measures in Wuhan City have played a key role in cutting off the transmission route of COVID-19 and protecting vulnerable groups.As a high-risk population,the elderly should be advised to maintain and strengthen a balanced diet with proper nutrition through increasing intake of aquatic food products,soybeans,fruits,and vegetables,reducing total caloric intake,and decreasing oil and salt consumption.These measures will be significant for the elderly to reduce the risk of chronic disease complications and COVID-19 infection and to decrease the chance of critical illness.Pengkun Song Cheng Li Ganyu Feng Jian Zhang Li Li Titi Yang Mingna Dong Ailing Liu Qi Zhang Yujing Liu Jinglei Wang Tanxi Ge Qing Yu Gangqiang Ding 2020China CDC weekly2020,2,27:0
