Blind individuals have been deprived of the use of diagrams as a form of knowledge representation and an aid to problem solving as well as a means of communication. Our focus is on providing them with access to a specific type of diagram – the node-link diagram, also known as a combinatorial graph. Graphs figure prominently in computer science and software engineering as well as chemistry and o...

BACKGROUND This study is an extension of a 28-week, randomized, double-blind, placebo-controlled study of memantine in 252 patients with moderate to severe Alzheimer disease. OBJECTIVE To evaluate long-term memantine treatment in moderate to severe Alzheimer disease. DESIGN, SETTING, AND PATIENTS Open-label, 24-week extension trial. Raters remained blind to the patients' initial study treat...

Non-orthogonal multiple access (NOMA) has been widely acclaimed as a promising solution to enhance spectral efficiency, increase user fairness, and scale up the number of users in wireless networks by enabling share symmetrical resources. This work is concerned with development implementation blind reconfigurable intelligent surface (RIS)-aided ordered NOMA (ONOMA) for smart reflector (SR) poin...

Blind image super-resolution (Blind-SR) is the process of leveraging a low-resolution (LR) image, with unknown degradation, to generate its high-resolution (HR) version. Most existing blind SR techniques use degradation estimator network explicitly estimate blur kernel guide supervision ground truth (GT) kernels. To solve this issue, it necessary design an implicit that can extract discriminati...
