The COVID-19 epidemic, caused by the SARS-CoV-2 virus, has resulted in 3352 deaths China as of April 12, 2020. This study aimed to investigate associations between particulate matter (PM) concentrations and case fatality rate (CFR) 49 Chinese cities, including epicenter Wuhan. We used Global Moran's I analyze spatial distribution autocorrelation CFRs, then we multivariate linear regression PM2.5 PM10 CFR. found positive PM pollution CFR cities both inside outside Hubei Province. For every 10...
Investigation of unloading rock failure under different σ2 facilitates the control mechanism excavation surrounding rock. This study focused on single-sided tests granite specimens true triaxial conditions. The strength and characteristics were studied with micro-camera acoustic emission (AE) monitoring. Furthermore, choice test path effect fracture discussed. Results show that increased can strengthen stability After unloading, rock's free surface underwent five phases, namely, inoculation,...
This study aims to explore the relationship between ambient NO2 levels and transmission ability (basic reproductive number, R0) of COVID-19 in 63 Chinese cities. After adjustment for temperature relative humidity, R0 was positively associated with concentration at city level. The temporal analysis within Hubei province indicated that all 11 cities (except Xianning City) had significant positive correlations (with 12-day time lag) (r > 0.51, p < 0.005). Since association may increase...
Elimination of hepatitis B virus (HBV) is a striking challenge for countries with high or moderate disease burden. Therefore, using China as practical case to share experiences similar may accelerate the achievement WHO 2030 target 90% reduction in HBV-related incidence. We aim evaluate impact national HBV immunization strategies China; and feasibility achieve targets under different scenarios.We constructed an expanded Susceptible-Exposed-Infectious-Recovered (SEIR) model decision...
Abstract The Coronavirus (COVID-19) epidemic, which was first reported in December 2019 Wuhan, China, has caused 3,314 death as of March 31, 2020 China. This study aimed to investigate the spatial associations daily particulate matter (PM) concentrations with rate COVID-19 We conducted a cross-sectional analysis examine PM2.5 and PM10 China through multiple linear regression method. found that held higher rates increasing concentration levels scale, may affect process patients developed from...
Deep rock are often in a true triaxial stress state. Studying the impacts of varying unloading speeds on their strain energy (SE) density is highly significant for predicting stability. Through principal experiments and equilibrium sandstone, this paper proposes method to compute SE compressive test. This aims analyze variation rocks under action stresses. Acoustic emission used verify correctness calculation paper. study found that: (1) Unloading one direction causes rise other directions....
To tackle the challenges of extensive drawing workloads and limited precision inherent in application block theory, this paper presents an optimization theory based on improved vector method. Additionally, Unwedge computer program is employed to conduct visual simulations applications, thereby enhancing ease utilizing theory. validate accuracy our research findings, we conducted a case study stability surrounding rock deeply buried underground caverns with complex geological structures at...
ABSTRACT Background Since its first case’s occurrence in Wuhan, China, the Coronavirus Disease 2019 (COVID-19) has been spreading rapidly to other provinces and neighboring countries. A series of intervention strategies have implemented, but didn’t stop spread. Methods Two mathematical models developed simulate current epidemic situation city Wuhan parts China. Special considerations were given mobility people for estimation forecast number asymptomatic infections, symptomatic infections...
While a COVID-19 vaccine protects people from serious illness and death, it remains concern when how to lift the high-cost strict non-pharmaceutical interventions (NPIs). This study examined joint effect of coverage NPIs on control local sporadic resurgence cases.Between July 2021 January 2022, we collected large-scale testing information case number imported patients website National Health Commission China. A compartment model was developed identify level that would allow safe relaxation...
The Coronavirus (COVID-19) epidemic, which was first reported in December 2019 Wuhan, China, has caused 219,331 confirmed cases as of 20 March 2020, with 81,301 being China. It been declared a pandemic by the World Health Organization 11 2020 (1). Although massive intervention measures have implemented China (e.g. shutting down cities, extending holidays and travel ban) many other countries, spread disease are unlikely to be stopped over world shortly. is becoming evident that environmental...
As of October 5, 2020, China has reported 2,921 cases imported from overseas. Assessing the effectiveness China's current policies on abroad is very important for and other countries that are facing or will face overseas cases. In April, we used a susceptible-exposed-infectious-recovered metapopulation model to simulate epidemic in seven foreign countries, three Chinese key cities. Based outside China, estimated proportion people incubation period calculated risk indexes cities through...
Abstract Background Hand, foot, and mouth disease (HFMD) is a common illness in young children. A monovalent vaccine has been developed China protecting against enterovirus-71, bivalent vaccines preventing HFMD caused by two viruses are under development. Objective To predict compare the incidence of different vaccination scenarios China. Methods We compartmental model to capture enterovirus transmission natural history children aged 0–5, calibrated reported cases same age-group from 2015...
(1) Background: It is important to improve vaccination strategies and immunization programs achieve herd immunity infectious diseases. (2) Methods: To assess the acceptance of COVID-19 vaccination, we conducted face-to-face surveys online in Shanghai, Zhejiang, Qinghai provinces. A fixed-effect model a random effects were used analyze factors associated with vaccination. (3) Findings: We initially recruited 3173 participants, 3172 participants completed full questionnaire (the response rate...
To investigate the influence of length-to-diameter ( L/D ) ratio and strain rate on evolution energy sandstone under uniaxial compression, experimental tests were conducted using RMT-150B rock mechanics test system. Specifically, compression experiments (UCE), loading-unloading experiment(ULUE) cyclic (UCLUE) performed. The results show that: 1) Based an investigation Kaiser effect in UCLUE, it is postulated that a small degree has negligible impact storage masses. hypothesis regarding...
Introduction The rise of live-stream selling has made the e-commerce platform attractive to many small and medium-sized retailers that are often faced with capital constraints. choice between financing (EPF) trade credit (TCF) for capital-constrained e-retailers engaging in is particularly important problem. Methods This paper considers a supply chain up manufacturer, an offers service consumers online retailer constraint. We, respectively, investigate optimal decisions enterprises under EPF...
Abstract The Coronavirus (COVID-19) epidemic, which was first reported in December 2019 Wuhan, China, has caused 3,314 death as of March 31, 2020 China. This study aimed to investigate the temporal association between case fatality rate (CFR) COVID-19 and particulate matter (PM) Wuhan. We conducted a time series analysis explore day-by-day associations. found held higher with increasing concentrations PM 2.5 10 scale, may affect process patients developed from mild severe finally influence...
During October 2021, China experienced localized outbreaks of COVID-19 in many cities. We analyzed the small local outbreak Zunyi (Guizhou Province), a major city southwestern China, and modeled effects different interventions on this outbreak.Data infections contacts, provided by Health Commission Guizhou Province, were used to analyze epidemiological characteristics calculate effectiveness vaccination.
