Repeatable Velocity Fine Structure of Lightning K‐Leaders From a Single VHF Interferometer Made Three‐Dimensional

Abstract K‐processes re‐illuminate lightning channels at speeds of order 10 7 m s −1 , but measuring their three‐dimensional (3‐D) propagation velocity has required multi‐station systems available at few sites. An error‐isomorphism range inversion upgrades a single very‐high‐freq...

Interactive Effects of Planting Density and Nitrogen Rate on Maize Root Architecture, Soil Nitrogen Cycling, and Water and Nitrogen Use Efficiencies

Optimizing planting density and nitrogen (N) application is essential for sustaining maize yield while reducing water use and N inputs. However, their interactive effects on belowground root development and the soil N environment remain poorly understood. A two-year field experim...

Optimizing biochar application strategies to improve soil properties and crop productivity in salt-affected croplands: Evidence from a global meta-analysis and machine learning approach

CONTEXT Salt-affected soils have become a major constraint on global food security and sustainable agricultural development by degrading soil structure, limiting nutrient availability, and suppressing crop growth. Biochar, characterized by its porous architecture, high carbon sta...

Role and diagnostic value of miR-3188 targeting OGT in regulating osteoblast function in delayed fracture healing of tibial fractures

This study investigated the role and mechanism of miR-3188 in delayed healing of tibial fractures, aiming to aid diagnosis and targeted intervention. A total of 172 patients with tibial fracture were enrolled and divided into normal fracture healing group (NFH, n = 82) and DFH (...

Effects of drought stress and Ca supply on photosynthesis, fluorescence parameters and growth of Glycyrrhiza uralensis in the Hexi Corridor

Calcium (Ca) functions as a secondary messenger and contributes to plant drought tolerance. This study examined how Ca supplementation influences photosynthetic performance and growth in Glycyrrhiza uralensis seedlings under drought stress. Drought significantly reduced net photo...
