In this paper, we use growing season Normalized Difference Vegetation Index (NDVI) as an indicator of plant growth to quantify the relationships between vegetation production and intra‐annual precipitation patterns for three major temperate biomes in China: grassland, deciduous broadleaf forest, coniferous forest. With increased precipitation, NDVI grassland forest increased, but that decreased. More frequent significantly did not alter at low levels constrained its high levels. The average...
The structure of age groups and social contacts the total population influenced infection scales hospital-bed requirements, especially severe infections deaths during global prevalence COVID-19. Before end year 2022, Chinese government implemented national vaccination had built herd immunity cross country, announced Twenty Measures (November 11) Ten New (December 7) for further modifications dynamic zero-COVID polity on mainland. With nation-wide modified measures background, Fuzhou COVID-19...
In the winters of 2012–2018, a total 25 'ultra-long' (≥6 days), wide-ranging pollution events occurred in northern China. The results showed that atmospheric circulation pattern corresponding to 62.5% persistent 'most serious' and 'more air China were blocking structures, 43.75% 500-hPa anomalies middle high latitudes Eurasia 'dual-blocking', 18.75% them 'single-blocking'. abnormally stable situation provided special background for occurrence maintenance heavy Okhotsk is significantly...
Hepatitis C virus (HCV) is a bloodborne that causes both acute and chronic hepatitis with the severity from mild illness to liver cirrhosis cancer. As one of major infectious diseases in China, monthly surveillance data Fujian Provincial Center for Disease Control Prevention shows increasing tendency 2004 2011, stable 2012 2016, declining 2017 2022. The 2004-2022 HCV infection Province affected by nation-wide main control measures Chinese government, because no are modified 2020 2022 during...
<abstract><p>In this study, we proposed two, symptom-dependent, HIV/AIDS models to investigate the dynamical properties of in Fujian Province. The basic reproduction number was obtained, and local global stabilities disease-free endemic equilibrium points were verified deterministic model. Moreover, indicators $ R_0^s R_0^e derived for stochastic model, conditions stationary distribution extinction investigated. By using surveillance data from Provincial Center Disease Control...
A COVID-19 outbreak in the rural areas of Shijiazhuang City was attributed to complex interactions among vaccination, host, and non-pharmaceutical interventions (NPIs). Herein, we investigated epidemiological characteristics all reported symptomatic cases by picking City, Hebei Province Northern China as research objective. In addition, established a with age-group mathematical model perform optimal fitting investigate dynamical profiles under three scenarios.All epidemic (January 2-February...
Since its emergence, SARS-CoV-2 virus, the causative agent of COVID-19, has undergone over three years evolutionary changes. Throughout this process, multiple variants, such as Alpha, Beta, Gamma, Delta, and Omicron, have emerged, leading to widespread outbreaks pandemics. A comprehensive analysis evolution past reveals progression through distinct stages.
The complex interactions were performed among non-pharmaceutical interventions, vaccinations, and hosts for all epidemics in mainland China during the spread of COVID-19. Specially, small-scale epidemic city described by SVEIR model was less found current studies. with control established to analyze dynamical epidemiological features two Jinzhou City led Omicron variants before after Twenty Measures. In this study, total population (N) divided into five compartments: susceptible (S),...
The epidemiological characteristics and distributions of two epidemics in Fujian Province Southeast China were attributed to the complex interactions among variant, host, non-pharmaceutical interventions (NPIs). All reported cases Putian epidemic (September 8–October 2, 2021, Delta variant B.1.617.2) Fuzhou (October 22–November 18, 2022, Omicron BA.5.2) classified by sex, age group, occupation, location this study. Using surveillance data from Provincial Center for Disease Control...
A vector–host model of dengue with multiple stages and independent fluctuations is investigated in this paper. Firstly, the existence uniqueness positive solution are shown by contradiction. When death rates aquatic mosquitoes, adult human beings respectively control intensities white noises, if R0s>1, then persistence mean for both infective mosquitoes derived. R0s>1 valid, stationary distribution derived through constructing several appropriate Lyapunov functions. If noises...
The differences of SARS-CoV-2 variants brought the changes transmission characteristics and clinical manifestations during prevalence COVID-19. In order to explore evolution mechanisms impacts variant evolution, classic SIR (Susceptible-Infected-Recovered) compartment model was modified a generalized SVEIR (Susceptible-Vaccinated-Exposed-Infected-Recovered) with age-group varying in this study. By using least squares method, optimal fittings against surveillance data from Fujian Provincial...
