Recent work has shown that sulfur hazes may arise in the atmospheres of some giant exoplanets, due to the photolysis of H2S. We investigate the impact such a haze would have on an exoplanet’s geometric albedo spectrum and how it may affect the direct imaging results of the Wide Field Infrared Survey Telescope (WFIRST), a planned NASA space telescope. For temperate (250 K<Teq<700 K) Jupiter-...

In this paper, we address the single-image haze removal problem in nighttime scenes. The night is a severely ill-posed due to presence of various visible light sources with varying colors and non-uniform illumination. These are different shapes introduce noticeable amount glow To overcome these effects, deep learning-based DeGlow–DeHaze iterative model which accounts for glows. proposed linear ...

Background: The effect of corticosteroid therapy on corneal wound healing is controversial. The objective of this study was to evaluate the effects of combination therapy with dexametha-sone and acetylcysteine at different times and durations on experimentally-induced corneal wounds and haze in rabbits. Methods: Eighteen adult New Zealand white rabbits were divided into three groups of ...

Particulate matter (PM) pollution has raised serious concerns for public health. Although outdoor individual protection could be achieved by facial masks, indoor air usually relies on expensive and energy-intensive air-filtering devices. Here, we introduce a transparent air filter for indoor air protection through windows that uses natural passive ventilation to effectively protect the indoor a...

purpose : although applying mitomycin c (mmc) during photorefractive keratectomy (prk) has shown to reduce postoperative corneal haze but there is considerable evidence of mmc toxicity in the literature and concerns exist regarding side effects and long-term complications. we conducted this study to compare the efficacy of mmc 0.02% and 0.01% in prevention of haze after prk. methods : 210 eyes ...

PURPOSE To evaluate the outcome of primary or retreatment photorefractive keratectomy (PRK) or phototherapeutic keratectomy (PTK) with mitomycin C (MMC) 0.02% applied prophylactically intraoperatively for the prevention of haze and regression in cases of significant haze and regression after primary PRK, due to previous radial keratotomy (RK), in primary PRK eyes with high myopia, and in comeas...
