UAV-LiDAR-Based Study on AGB Response to Stand Structure and Its Estimation in Cunninghamia Lanceolata Plantations

open access: yesRemote Sensing
Forest spatial structure is of significant importance for studying forest biomass accumulation and management. However, above-ground biomass (AGB) estimation based on satellite remote sensing struggles to capture forest spatial structure information ...

Simulation for field emission images of micrometer-long SWCNTs

open access: yes, 2009
The electron distribution of open-ended single-walled carbon nanotubes with chirality indexes (7,0) and (5,5) in the field emission conditions was calculated via a multi-scaled algorithm. The field emission images were produced numerically.

Unveiling High‐Resolution CH4 Profiles Over Southeast China: Novel Insights From AirCore Balloon Observations

open access: yesGeophysical Research Letters
Vertical profiles of methane (CH4) are essential for validating satellite observations and quantifying regional sources and sinks. This study presents the first two high‐resolution CH4 profiles (0–25 km) over southeastern China, an economically developed

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Quantitative investigation of moisture migration during microwave drying of coal slime dough through simulation and tracer analysis

open access: yesScientific Reports
Moisture migration during the microwave drying process of coal slime is critical for improving drying efficiency and reducing energy consumption. Nevertheless, current methods for quantifying these migration behaviors remain insufficient.
