INDIVIDUAL TREE PARAMETERS ESTIMATION FOR CHINESE FIR (CUNNINGHAMIA LANCEOLATE (LAMB.) HOOK) PLANTATIONS OF SOUTH CHINA USING UAV OBLIQUE PHOTOGRAPHY: POSSIBILITIES AND CHALLENGES

Individual Tree Parameters Estimation for Chinese Fir (Cunninghamia lanceolate (Lamb.) Hook) Plantations of South China Using UAV Oblique Photography: Possibilities and Challenges

Chinese fir (Cunninghamia lanceolate (Lamb.) Hook) individual tree parameters extraction is important for scientific forest management.However, high-precision parameters extraction by field investigation or spaceborne optical remote sensing is difficult when the forest is dense and the terrain is complex.This article proposes a framework for extrac

Positive end-expiratory pressure (PEEP) level to prevent expiratory flow limitation during cardiac surgery: study protocol for a randomized clinical trial (EFLcore study)

Abstract Background Lung dysfunction commonly occurs after cardiopulmonary bypass (CPB).Randomized evidence suggests that the presence of expiratory flow limitation (EFL) in major abdominal surgery is associated with postoperative pulmonary complications.Appropriate lung recruitment and a correctly set positive end-expiratory pressure (PEEP) level

Fragile Treg cells: Traitors in immune homeostasis?

Regulatory T (Treg) cells play a key role in maintaining immune tolerance and tissue homeostasis.However, in some disease microenvironments, Treg cells exhibit fragility, which manifests as preserved FoxP3 expression accompanied by inflammation and loss of immunosuppression.Fragile Treg cells are formatively, phenotypically and functionally diverse
