Anti-pollution flashover of insulator is important for power systems. In recent years, haze-fog weather occurs frequently, which makes discharge occurs easily on the insulator surface and accelerates insulation aging of insulator. In order to study the influence of haze-fog on the surface discharge of room temperature vulcanized silicone rubber, an artificial haze-fog lab was established. Based...

Unmanned aerial vehicles (UAVs) have gradually become a major air threat to ships because of small size, good maneuverability, and low cost. Vision-based UAV detection offers one the main ways identify protect against UAVs. Unlike land environment, weather is complicated at sea. The visibility an object undermined by such factors as sea fog sunlight, which makes it difficult detect UAVs through...

Additional size-resolved chemical information is needed before the physicochemical characteristics and sources of airborne particles can be understood; however, this information remains unavailable in most regions of China due to lacking measurement data. In this study, we report observations of various chemical species in size-segregated particle samples that were collected over 1 year in the ...

Recognizing whether a planet can support life is a primary goal of future exoplanet spectral characterization missions, but past research on habitability assessment has largely ignored the vastly different conditions that have existed in our planet's long habitable history. This study presents simulations of a habitable yet dramatically different phase of Earth's history, when the atmosphere co...

PURPOSE: To report persistent subepithelial haze in two patients following femtosecond LASIK associated with creation of a thin fl ap. METHODS: Subepithelial haze was assessed by slit-lamp photography, high-resolution Scheimpfl ug imaging, and corneal confocal microscopy. RESULTS: Two patients showed distinct subepithelial haze and reduced corrected distance visual acuity at 3 months after LASI...

PURPOSE The effects of various eye drops on corneal wound healing, particularly in the subepithelial haze area, were investigated histologically following superficial keratectomy in rabbits. METHODS Mechanical superficial keratectomy was performed in rabbit eyes. Tranilast, betamethasone, hyaluronic acid, and diclofenac eye drops were administered after the procedure. Physiological saline was...
