USB Dead Drop
A USB dead drop is a USB mass storage device installed in a public space. For example, a USB flash drive might be mounted in an outdoor brick wall and fixed in place with fast concrete. Members of the public are implicitly invited to find files, or leave files, on a dead drop by directly plugging their laptop into the wall-mounted USB stick in order to transfer data. (It is also possible to use smartphones and tablets for this purpose, by utilizing a USB on-the-go cable.) The dead drops can therefore be regarded as an anonymous, offline, peer-to-peer file sharing network. However, in practice USB dead drops are often used for social or artistic reasons, rather than for practical ones.

Usage-Based Insurance Policy Auction Mechanism
An auction mechanism is developed for the UBI blockchain platform to enhance consumer trust. The study identifies correlations between driving behaviors and associated risks to determine a driver’s score. A decentralized bidding algorithm is proposed and implemented on a blockchain platform using elliptic curve cryptography and first-price sealed-bid auctions.

URL Normalization
URL normalization is the process by which URLs are modified and standardized in a consistent manner. The goal of the normalization process is to transform a URL into a normalized URL so it is possible to determine if two syntactically different URLs may be equivalent. Search engines employ URL normalization in order to assign importance to web pages[clarify] and to reduce indexing of duplicate pages. Web crawlers perform URL normalization in order to avoid crawling the same resource more than once. Web browsers may perform normalization to determine if a link has been visited or to determine if a page has been cached.

Urban Scene Reconstruction via Neural Radiance Fields
3D reconstruction of urban scenes is an important research topic in remote sensing. Neural Radiance Fields (NeRFs) offer an efficient solution for both structure recovery and novel view synthesis. The realistic 3D urban models generated by NeRFs have potential future applications in simulation for autonomous driving, as well as in Augmented and Virtual Reality (AR/VR) experiences.

Urban Flood Monitoring Technology
Owing to rapid climate change, large-scale floods have occurred yearly in cities worldwide, causing serious damage. General flooding and overflow modeling was performed based on a model that utilizes the flow of water and its geographical characteristics. More detailed geographical data and drainage network information are utilized in urban regions.

Upper Tract Urothelial Carcinoma
Upper tract urothelial carcinoma (UTUC) is a rare malignancy, occurring in 5–10% of patients diagnosed with UC, and involves the renal pelvis, calyces, or ureters. UTUC can be sporadic or hereditary as a clinical manifestation of Lynch syndrome. Therapeutic management of these patients is challenging. Following risk stratification of localized disease, patients with low-grade UTUC may undergo kidney-sparing surgery or radical nephroureterectomy (RNU) and/or chemoablation with mitomycin-c instillation to reduce recurrence.

Uplay
Uplay is a digital distribution, digital rights management, multiplayer and communications service developed by Ubisoft to provide an experience similar to the achievements/trophies offered by various other game companies. The service is provided across various platforms. Uplay is used exclusively by first-party Ubisoft games, and although some third-party ones are sold through the Uplay store, they do not use the Uplay platform. Responses to the platform have been generally negative, with coverage comparing it negatively to its competitors and calling it the worst part of Ubisoft's games.
