We study the problem of computing isochrones in road networks, where the objective is to identify the region that is reachable from a given source within a certain amount of time. While there is a wide range of practical applications for this problem (e. g., reachability analyses, geomarketing, visualizing the cruising range of a vehicle), there has been little research on fast computation of i...

in the new millennium, information technology (it) has become very effective and this is becoming evident in both developed and developing countries. these areas are especially within the fields of information gathering, in the broadest sense, and of developing and strengthening networks both internal and external to the surrounding environment. today, more and more companies, organizations and...

PURPOSE We compared phospholipid (phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, and phosphatidylinositol) profiles of control and glaucomatous trabecular meshwork (TM) derived from human donors. METHODS Control TM and most primary open angle glaucoma (POAG) TM were collected from cadaver donors. A select subset of POAG surgical TM samples also were collected for analyses....
