In order to meet the fast and accurate automatic detection requirements of equipment maintenance in railway tunnels in the era of high-speed railways, as well as adapting to the high dynamic, low-illumination imaging environment formed by strong light at the tunnel exit, we propose an automatic inspection solution based on panoramic imaging and object recognition with deep learning. We installed a hyperboloid catadioptric panoramic imaging system on an inspection vehicle to obtain a large field of view as well as to shield the high dynamic phenomena at the tunnel exit, and proposed a YOLOv5-CCFE object detection model based on railway equipment recognition. The experimental results show that the mAP@0.5 value of the YOLOv5-CCFE model reaches 98.6%, and mAP@0.5:0.95 reaches 68.9%. The FPS value is 158, which can meet the automatic inspection requirements of railway tunnel equipment along the line and has high practical application value.

The regulation of photoperiod and light intensity significantly affected Agastache rugosa by enhancing growth, modifying flowering dynamics, and promoting the accumulation of key phenolic compounds. Agastache rugosa is a medicinal and aromatic plant valued for its bioactive compounds, which contribute to its application in the flavoring, perfume, and food industries. However, variability in the composition of the bioactive compounds poses challenges for its commercial utilization.

Skull base surgery requires precise spatial recognition; however, existing educational tools remain limited. To address this issue, we developed a step-by-step stereotactic three-dimensional anatomical model of the anterior transpetrosal approach using digital photogrammetry. Cadaveric dissection was subsequently performed in 17 steps, of which 10 were reconstructed into three-dimensional models.

As a critical component in hydropower systems, the Hydraulic Turbine Regulation System (HTRS) exhibits strong coupling characteristics that impose substantial challenges on control system design, necessitating the development of high-performance control strategies. To address the complex control requirements, this paper proposes an improved T-S fuzzy modeling method based on the Luenberger observer theory. It constructs a system model that combines high accuracy and simplicity.

As key pollinators, bees are increasingly threatened by environmental stressors such as heavy metals, pesticides, and temperature fluctuations, which can cause oxidative stress and disrupt cellular homeostasis. Glutathione S-transferases (GSTs) play crucial roles in antioxidant defense and detoxification, yet systematic studies on bee GST families remain limited. Here, we conducted a genome-wide analysis of cytosolic GST genes in 13 bee species, identifying 146 genes in total.
