<h3>Importance</h3> Although effective vaccines against COVID-19 have been developed, additional are still needed. <h3>Objective</h3> To evaluate the efficacy and adverse events of 2 inactivated vaccines. <h3>Design, Setting, Participants</h3> Prespecified interim analysis an ongoing randomized, double-blind, phase 3 trial in United Arab Emirates Bahrain among adults 18 years older without known history COVID-19. Study enrollment began on July 16, 2020. Data sets used for were locked...
Although SARS-CoV-2 infection often causes milder symptoms in children and adolescents, young people might still play a key part transmission. An efficacious vaccine for adolescents could therefore assist pandemic control. For further evaluation of the inactivated COVID-19 candidate BBIBP-CorV, we assessed safety immunogenicity BBIBP-CorV participants aged 3-17 years.
Summary Soil salinity acts as a critical environmental filter on microbial communities, but the consequences for diversity and biogeochemical processes are poorly understood. Here, we characterized soil bacterial communities functional genes in coastal estuarine wetland ecosystem across gradient (~5 km) ranging from oligohaline to hypersaline habitats by applying PCR‐amplified 16S rRNA (rRNA) sequencing microarray‐based GeoChip 5.0 respectively. Results showed that saline soils marine...
The climatic warming and humidification observed in the arid region of Northwest China (ARNC) their impacts on ecological environment have become an issue concern. associated multi-scale characteristics environmental responses are currently poorly understood. Using data from satellite remote sensing, field observations, Coupled Model Intercomparison Project phase 6, this paper systematically analyzes process scale ARNC vegetation. results show that not only temperature precipitation...
Aboveground net primary production (ANPP) is strongly correlated with annual precipitation (AP) in grassland ecosystems. However, the relationship between interannual variation ANPP and variability remains controversial. In this study, we used long‐term data of biomass from 118 sites across global grasslands to examine AP. Our results showed that increased precipitation, but leveled off humid regions, led an increase ANPP. The relative maxima significantly AP minima also positively minima....
Lakes are an important component of the climate system. They provide moisture for precipitation, buffer temperature variations, and contribute to regional atmospheric carbon budgets. This article describes eddy covariance (EC) mesonet on Lake Taihu, a large (area 2400 km2) shallow (depth 2 m) lake situated in heavily populated Yangtze River Delta, China. The consists five sites, representing different biological attributes wind–wave patterns, land site near shore. Common all sites standard...
Abstract Models of lake physical processes provide the lower flux boundary conditions for numerical predictions weather and climate in basins. So far, there have been few studies on evaluating model performance at diurnal time scale against observations. The goal this paper is to evaluate National Center Atmospheric Research Community Land Model version 4–Lake, Ice, Snow Sediment Simulator using eddy covariance water temperature data obtained a subtropical freshwater lake, Lake Taihu, China....
Inland lakes play important roles in water and greenhouse gas cycling the environment. This study aims to test performance of a flux-gradient system for simultaneous measurement fluxes vapor, CO2, CH4 at lake–air interface. The concentration gradients over surface were measured with an analyzer based on wavelength-scanned cavity ring-down spectroscopy technology, eddy diffusivity was sonic anemometer. Results zero-gradient indicate flux precision 4.8 W m–2 0.010 mg s–1 0.029 μg CH4. During...
Abstract The oxygen isotopes of water (H 2 18 O and H 16 O) are tracers widely used for the investigation Earth science problems. tracer applications based on premise that O/ ratio open‐water evaporation ( δ E ) can be calculated from environmental conditions. A long‐standing issue concerns role kinetic fractionation, or diffusion transport, in process. Here we deployed an optical instrument at a large lake (area 2,400 km to make situ measurement D atmospheric vapor, then determined using...
Plant invasion alters the fundamental structure and function of native ecosystems by affecting biogeochemical pools fluxes materials energy. Native (Suaeda salsa) invasive (Spartina alterniflora) salt marshes were selected to study effects Spartina alterniflora on soil organic carbon (SOC) contents stocks in Yellow River Delta. Results showed that SOC (g/kg) (kg/m2) significantly increased (P < 0.05) after seven years, especially for surface layer (0–20 cm). The exhibited an even...
Abstract The deviations of the Priestley‐Taylor (PT) coefficient from a fixed value around 1.26 indicate nonlinear dependence wet surface evaporation ( ) on equilibrium , which is radiation term in Penman potential [ ]). linear PT equation with underestimates for small but overestimates large whereas calibrated wind function has opposite bias. In this study, sigmoid generalized complementary (SGC) by Han and Tian (2018a), https://doi.org/10.1029/2017wr021755 was applied to estimate setting...
Lakes are major emitters of methane (CH4); however, a longstanding challenge with quantifying the magnitude emissions remains as result large spatial and temporal variability. This study was designed to address issue using satellite remote sensing advantages coverage resolution. Using Aqua/MODIS imagery (2003–2020) in situ measured data (2011–2017) eutrophic Lake Taihu, we compared performance eight machine learning models predict diffusive CH4 found that random forest (RF) model achieved...
Abstract Does lake evaporation increase or decrease under the scenario of climate warming? This paper aims to answer this question by investigating controlling mechanism interannual variations in at a subtropical lake. The research methodology is based on continuous eddy covariance measurement over >7 years and diagnostic analysis using surface energy balance principle. results indicate that was enhanced mainly increasing inputs including solar radiation incoming longwave weakened...
Abstract Climate models generally predict higher precipitation in a future warmer climate. Whether the intensification occurred response to historical warming continues be subject of debate. Here, using observations ocean surface energy balance as hydrological constraint, we find that intensified at rate 0.68 ± 0.51% K −1 , which is slightly than multi-model mean calculation for climate (0.38 1.18% ). The reduction albedo associated with melting sea ice positive contributor temperature...
