Uncertainty in aquatic greenhouse gas flux estimates arises from subjective processing of floating chamber time series

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate quantification of greenhouse gas (GHG) fluxes from aquatic systems is essential for constraining regional and global carbon budgets. Closed floating chambers are widely used to measure carbon dioxide (CO2) and methane (CH4) fluxes at the water–air interface, yet large uncertainties persist due to subjective processing of chamber time ...

Redistributive effects of unsteady flow regimes downstream of reservoirs

River, EarlyView.
Abstract Understanding unsteady flow regimes in river channels downstream of a reservoir, is essential for predicting and regulating water level and flow velocity in the lower basin. Using hourly observations of discharge and water level at Xiangjiaba Station from 2018 to 2022, an evaluation indicator was proposed to analyze unsteady flow regimes ...

Preventive Application of House Dust Mite‐Sublingual Immunotherapy Induces Blocking Antibodies in Sensitized Preschool Children

Allergy, EarlyView.
HDM‐pSLIT induced IgG, IgG1, and IgG4 specific to major HDM allergens in sensitized non‐allergic preschool children without increasing HDM‐sIgE. It blunted the development of new sensitizations and reduced HDM reactivity in skin and basophils. HDM‐pSLIT treated children displayed a blocking effect on HDM‐induced basophil activation.
