Research on women’s social media practices in Muslim societies has primarily focused middle-class or elite women, such as influencers, activists, and members of online communities. However, we know little about working-class use contexts. Using ethnography interviews, I analyze TikTok’s early popularity with women Pakistan report three main findings. First, initial reception was fractured acros...

by MICHAEL ENGLES (Under the Direction of Billy R. Hammond, Jr.) ABSTRACT The macular pigment (MP) is composed of diet-derived carotenoids that screen blue light and are concentrated in and around the fovea. Several functions for the MP have been proposed. The earliest hypothesis, termed the Acuity Hypothesis, predicts that increased MP optical density should improve spatial vision by reducing ...

Given a single input rainy image, our goal is to visually remove rain streaks and the veiling effect caused by scattering and transmission of rain streaks and rain droplets. We are particularly concerned with heavy rain, where rain streaks of various sizes and directions can overlap each other and the veiling effect reduces contrast severely. To achieve our goal, we introduce a scale-aware mult...

Near IR spectra at low (R∼800) and medium (R∼9000) resolution, obtained with ISAAC at VLT, have been used to pose constraints on the evolutionary state and accretion properties of a sample of five embedded YSOs located in the R CrA core. This sample includes three Class I sources (HH100 IR, IRS2 and IRS5), and two sources with NIR excesses (IRS6 and IRS3). IRS5 and IRS6 have been discovered to ...

In photography, the presence of a bright light source often reduces quality and readability resulting image. Light rays reflect bounce off camera elements, sensor or diaphragm causing unwanted artifacts. These artifacts are generally known as "lens flare" may have different influences on photo: reduce contrast image (veiling glare), add circular circular-like effects (ghosting flare), appear sp...

We present a study of accretion in a sample of 45 young, low mass objects in a variety of star forming regions and young associations, about half of which are likely substellar. Based primarily on the presence of broad, asymmetric Hα emission, we have identified 13 objects (∼30% of our sample) which are strong candidates for ongoing accretion. At least 3 of these are substellar. We do not detec...
