In response to the problem of poor accuracy and the large model size in transmission line foreign object detection, an improved YOLOv7- tiny algorithm based on channel pruning has been proposed. Firstly, the ReXNet network is used to replace the backbone network of YOLOv7-tiny to address the feature bottleneck issue in the original network. Secondly, diversified branch blocks are introduced to enhance the network's feature fusion capability. Finally, through layer-adaptive magnitude-based pruning (LAMP), a pruning approach is employed to trade off some accuracy for a reduction in model size and computational load, preparing it for deployment on embedded devices. Experimental results indicate that the final improved model achieves a 3 percentage points increase in accuracy compared to the YOLOv7-tiny model, a 119.4% increase in FPS, and compresses the model size to 14% of the original size.

Objective: The aim of this study is to investigate the potential application of loop-mediated isothermal amplification technology (LAMP) in the diagnosis of pulmonary tuberculosis. Methods: The clinical data of 305 patients with suspected tuberculosis admitted to Baoding Second Central Hospital from June 2020 to June 2023 were retrospectively analyzed. Based on the pathological results, the non-tuberculosis group (123 cases) and tuberculosis group (182 cases) were included. The sputum samples with different traits, using modified Roche culture method, smear acid stain method and LAMP detection of Mycobacterium tuberculosis. Results: Compared with the smear acid-fast staining method and the improved Roche culture method, the positive rate of LAMP samples was relatively high, and the positive rate of LAMP samples with cheese sputum was relatively high compared with other samples. The results of acid-fast staining showed that 80 cases were positive, 119 cases were negative, 4 cases were misdiagnosed and 102 cases were missed. The results of modified Roche culture showed that 104 cases were positive, 120 cases were negative, 3 cases were misdiagnosed and 78 cases were missed. LAMP results showed that 135 cases were positive, 121 cases were negative, 2 cases were misdiagnosed and 47 cases were missed. Compared with smear acid staining method and modified Roche culture method, the sensitivity, negative predictive value, accuracy and area under the curve (AUC) value of LAMP examination were relatively high, in which the sensitivity, accuracy and AUC value of smear acid staining method were lower than those of modified Roche culture method (P<0.05). Conclusion: LAMP technique was beneficial to the identification of Mycobacterium tuberculosis in various trait samples, and had high diagnostic sensitivity, negative predictive value and accuracy for Mycobacterium tuberculosis in sputum samples, which had higher diagnostic value for pulmonary tuberculosis.

Pulsed xenon lamp is often used for performance testing of solar cells because its spectrum is most similar to sunlight. The pulsed xenon lamp power supply is the key factor to ensure the reliable operation of the pulsed xenon lamp and improve the photoelectric conversion efficiency. In order to solve the problems of the traditional pulsed xenon lamp power supply with large volume, large noise interference and low reliability, a highreliability pulsed xenon lamp power supply was designed. Staggered parallel Buck was adopted to reduce the output ripple, and the digital control scheme of the improved nested working sequence was used to improve the working reliability of the pulsed xenon lamp. By building an experimental prototype and testing, it is proved that the pulsed power supply can make the pulsed xenon lamp light up 100% and keep working stably. [ABSTRACT FROM AUTHOR]
