However, current local path planning methods often result in trajectories with numerous sharp or inflection points, which are not ideal for smooth UAV flight. This paper introduces a UAV path planning approach based on distance gradients.

Antimicrobial peptides (AMPs) are small-molecule peptides that play a vital role in the nonspecific immune defense system of organisms. They mainly kill microorganisms by physically destroying the cell membrane and causing the leakage of contents. AMPs have attracted much attention as potential alternatives to antibiotics due to their low susceptibility to resistance.

Large-scale utilization of high-alkali fuels is considered an effective solution for alleviating energy shortages and reducing CO emissions. However, combustion of high-alkali fuels in boilers releases alkali metals into the flue gas, which leads to severe ash deposition and corrosion on the heating surface. Consequently, research into the efficient use of highly alkaline fuels has been conducted in recent years.

Photovoltaic (PV) cell defect detection has become a prominent problem in the development of the PV industry; however, the entire industry lacks effective technical means. In this paper, we propose a deep-learning-based defect detection method for photovoltaic cells, which addresses two technical challenges: (1) to propose a method for data enhancement and category weight assignment, which effectively mitigates the impact of the problem of scant data and data imbalance on model performance; (2) to propose a feature fusion method based on ResNet152-Xception. A coordinate attention (CA) mechanism is incorporated into the feature map to enhance the feature extraction capability of the existing model.

However, fabrications and applications of solar-blind PSDs remain yet to be harnessed. Herein, we demonstrate a solar-blind PSD developed from a graphene/GaO Schottky junction with a 25-nanometer-thick GaO film, in which the absorption of the nanometer-thick GaO is enhanced by multibeam interference.

However, little attention has been paid to photomemories working in the solar-blind region so far, which may have unique advantages of insusceptibility to ambient light and higher capacity. Herein, we propose and demonstrate a GaO based solar-blind photomemory array with logic, arithmetic, and optoelectronic memory functions.

Background: Schistosomiasis japonica is an infectious disease caused by Schistosoma japonicum that seriously endangers human health. Domestic animals have important roles in disease transmission and goats are considered a primary reservoir host and source of infection. The prevalence and intensity of schistosomiasis infections have significantly decreased in China, and a more sensitive, specific detection method is urgently needed.

In this work, MoS@γ-FeO, formed by the sulfuration of phosphomolybdic acid (HPMo)-grafted γ-FeO, was developed as a magnetic and regenerable sorbent to recover gaseous Hg from coal-fired flue gas as a cobenefit to the use of wet electrostatic precipitators. The thermal stability of γ-FeO was notably enhanced by HPMo grafting; thus, the magnetization of MoS@γ-FeO hardly decreased during the application.

In this study, Ti was incorporated into sulfurated γ-FeO to improve its performance for capturing Hg from smelting flue gas, and the mechanism of Ti incorporation on Hg adsorption onto sulfurated γ-FeO was investigated by comparing the kinetic parameters. The kinetic analysis showed that the Hg adsorption rate primarily depended on the amounts of surface adsorption sites for the physical adsorption of Hg and surface S for Hg oxidation.

Pancreatic stellate cells (PSC) have become a research hotspot in recent years, and play a vital role in PDAC microenvironment by secreting soluble factors such as transforming growth factor β, interleukin-6, stromal cell-derived factor-1, hepatocyte growth factor and galectin-1. These PSC-derived cytokines and proteins contribute to PSC activation, participating in PDAC cell proliferation, migration, fibrosis, angiogenesis, immunosuppression, epithelial-mesenchymal transition, and chemoradiation resistance, leading to malignant outcome.

SSCs were identified by alkaline phosphatase staining and SSEA-1 fluorescence. The EGFP gene was transfected into SSCs by three different methods: electroporation, liposome transfer and calcium acid phosphate precipitation.
