Abstract Efficient and accurate insulator defect detection is essential for maintaining the safe stable operation of transmission lines. However, effectiveness adversely impacted by complex changeable environmental backgrounds, particularly under extreme weather that elevates accident risks. Therefore, this research proposes a high‐precision intelligent strategy based on synthetic algorithm improved YOLOv7 detecting defects weather. The proposed methodology involves augmenting dataset with...
To address the technical challenge of rapid and reliable interruption DC faults in offshore wind power collection transmission systems, which are critical for large-scale renewable energy integration, this paper proposes an integrated multi-port circuit breaker (DCCB) with bus fault clearing capability based on a dual H-bridge configuration. By extending pair bridge arms to connect employing diodes load commutation switches (LCSs) form second H-bridge, proposed DCCB not only achieves...
Maize, the world’s most widely cultivated food crop, is critical in global security. Low temperatures significantly hinder maize seedling growth, development, and yield formation. Efficient accurate assessment of quality under cold stress essential for selecting cold-tolerant varieties guiding field management strategies. However, existing evaluation methods lack a multimodal approach, resulting inefficiencies inaccuracies. This study combines phenotypic extraction technologies with...
Abstract Day length modulates hypocotyl elongation in seedlings to optimize their overall fitness. Variations cell growth‐associated genes are regulated by several transcription factors. However, the specific factors through which plant clock increases fitness still being elucidated. In this study, we identified no apical meristem, Arabidopsis thaliana ‐activating factor (ATAF‐1/2), and cup‐shaped cotyledon (NAC) family ATAF1 as a novel repressor of under short‐day (SD) photoperiod. day...
Background: Imported cases of infectious disease provide invaluable information about epidemiological conditions abroad, and should guide treatment decisions at home abroad.Here, we examined malaria imported from Africa to China for mutations eroding the efficacy sulfadoxine-pyrimethamine (SP), sometimes used as an intermittent preventive during pregnant women infants.Methods: A total 208 blood samples were collected P. falciparum-infected workers who had returned Western Central Guangxi...
The insulation coordination of the converter station is very important for security and economy UHVDC power transmission system, lightning surge overvoltages at should be calculated accurately. This paper mainly analyzes influence modeling methods on caused by backflashover incoming dc lines using PSCAD program, such as selection stroke current waveform, tower model, flashover criterion insulator, so on. simulation results show that have a great withstand level lines, but their influences...
Background: Low-temperature stress significantly restricts maize germination, seedling growth and development, yield formation. However, traditional methods of evaluating quality are inefficient. This study established a method grading based on phenotypic extraction deep learning. Methods: A pot experiment was conducted using different low-temperature combinations treatment durations at six stages between the sowing phases. Changes in 27 indices, including plant morphology photosynthetic...
Plasmodium vivax transmission in West Africa, dominant for the Duffy-negative blood group, has been increasingly recognized from both local residents as well international travelers who contracted P. malaria there. However, relapsing pattern and sensitivity to antimalarial treatment of strains originated this region are largely unknown. There is evidence that efficacy primaquine radical cure depends on host factors such hepatic enzyme cytochrome P450 (CYP) 2D6.A 49-year-old Chinese man was...
The burgeoning demand for enhanced power-system safety means that there is increased attention on technologies the detection and location of cable faults. double-terminal fault method, which senses a current using transformer (CT), most effective widely applied method in industrial practice. However, CT sensors may suffer from magnetic saturation when exposed to high current, resulting significant errors, their sensitivity cannot be adjusted. To address this problem, paper describes an...
Partial discharge (PD) detection has proven to be one of the most acceptable techniques for insulation estimation power apparatus. A powerful tool conducting on‐site PD and location in cables is urgently needed. In view this issue, study covers research development efforts design, implement, test a novel damped AC (DAC) system based on frequency‐tuned resonant technique (AC–DAC). This gives cost‐effective solution cables. The topology operation principle proposed are presented described....
Photodynamic therapy (PDT) agents induce photodamage only where photosensitizers localize in tumor cells. Since apoptosis is a major pathway of PDT-mediated cell death vivo, the therapeutic efficacy PDT drugs against cells may be improved by regulating intrinsic apoptosis. Mitochondria are intracellular organelles that regulate apoptosis, thus triphenylphosphonium, well-known mitochondria-targeting molecule, was appended to photoactive platinum diimine complex. The ability...
