High-standard farmland construction (HSFC) is a key measure to ensure national food security. The development of digital technology has brought new opportunities for HSFC. Based on panel data from 30 provinces (municipalities and autonomous regions), this paper employs a two-way fixed effects model,...

Based on strip-tillage technology, this study explores the optimal seedbed environment for maize growth through a three-year field agronomic experiment. A comparative analysis of two planting modes, flat planting and ridge planting, was conducted, and a two-factor, three-level experimental design wa...

Study region: The Asian water tower (AWT) encompasses the Tibetan Plateau and adjacent mountain ranges. Study focus: The AWT serves as a key water supplier for China, yet its economic role has not been adequately quantified. To address this gap, we employ a hydro-economic model to quantitatively ass...

Landscape patch patterns are extensively used to reflect the functions and states of ecosystems, significantly influencing eco-hydrological processes. Fragmented patch patterns are common in alpine meadows on the Qinghai-Tibetan Plateau (QTP), potentially leading to the redistribution of water resou...

Objective: To investigate the therapeutic effect of an ilioinguinal lobed flap in the early repair of facial and neck injuries caused by sulfuric acid burn. Methods: A retrospective analysis was carried out on the case of a 29-year-old female patient with sulfuric acid burns. Initially, a left ilioi...

BackgroundPulmonary fibrosis (PF) remains a devastating disease with limited therapeutic options. Astragaloside IV (AS-IV), a natural compound from Astragalus mongholicus (AM), has shown promise as a possible treatment for fibrosis. However, a systematic evaluation of its therapeutic efficacy and un...

We utilized phase-field simulations to investigate the effects of polar-axis (PA) orientation fluctuations on the extrinsic properties of single ferroelectric (FE) grains, focusing on the coercive electrical field (EC) and the remnant polarization (Pr). The underlying mechanisms through which PA ori...

The SQUAMOSA promoter binding protein (SBP)-box genes encode a kind of plant-specific transcription factors (TFs) and play important roles in the regulation of plant development. In this study, a genome-wide characterization of this family was conducted in maize (Zea mays). Thirty-one SBP-box genes...

The loads of a model tilt-proprotor with a gimbaled hub were measured in the wind tunnel of CHRDI, operating at 90°, 80°, 70°, 60°, and 45° inclination angles to represent the rotor loads of helicopter and transient flight modes. The flap, lead-lag moments, and pitch rod forces were measured. A comp...

Antivirus (patch) is one of the most powerful tools for defending against malware spread. Distributed patching is superior to its centralized counterpart in terms of significantly lower bandwidth requirement. Under the distributed patching mechanism, a novel malware propagation model with double del...

Background Hyperparathyroidism (HPT) is classified into primary HPT (PHPT), secondary HPT (SHPT), tertiary HPT (THPT), and pseudohyperparathyroidism. Parathyroid surgery is generally reserved for patients with symptomatic PHPT and asymptomatic patients who meet the surgical guideline criteria. Howev...
