The Comparative Legal Landscape Of Educational Pluralism, Nicole Stelle Garnett

Arkansas Law Review

In the United States, debates about private and faith-based education tend to focus on questions about government funding: which kinds of schools should the government fund (and at what levels)? Should, for example, students be able to use public funds to attend privately operated schools? Faith-based schools? If so, what policy mechanisms should be used to fund private schools—vouchers, tax credits, direct transfer payments? How much funding should these schools receive? The same amount as public schools or less? As a historical matter, the focus on funding in the United States makes sense because only public (that is, government-operated) elementary …

Image Spam Classification With Deep Neural Networks, Ajay Pal Singh, Katerina Potika

Faculty Publications, Computer Science

Image classification is a fundamental problem of computer vision and pattern recognition. We focus on images that contain spam. Spam is unwanted bulk content, and image spam is unwanted content embedded inside the images. Image spam potentially creates a threat to the credibility of any email-based communication system. While a lot of machine learning techniques are successful in detecting textual based spam, this is not the case for image spams, which can easily evade these textual-spam detection systems. In our work, we explore and evaluate four deep learning techniques that detect image spams. First, we train deep neural networks using …

Salinomycin Inhibits Proliferative Vitreoretinopathy Formation In A Mouse Model., Alison M. Heffer, Victor Wang, Richard T. Libby, Steven E. Feldon, Collynn F. Woeller, Ajay E. Kuriyan

Wills Eye Hospital Papers

Proliferative vitreoretinopathy (PVR) is a progressive disease that develops in a subset of patients who undergo surgery for retinal detachment repair, and results in significant vision loss. PVR is characterized by the migration of retinal pigment epithelial (RPE) cells into the vitreous cavity, where they undergo epithelial-to-mesenchymal transition and form contractile membranes within the vitreous and along the retina, resulting in recurrent retinal detachments. Currently, surgical intervention is the only treatment for PVR and there are no pharmacological agents that effectively inhibit or prevent PVR formation. Here, we show that a single intravitreal injection of the polyether ionophore salinomycin (SNC) …
