Abstract: A visibility-enhanced corrugated structure is provided. The structure includes a base tube having an internal passage that slideably receives an inner element such as a hose, cable or fluid. A rub strip is provided on crests of the corrugated structure to mitigate abrasion wear of structures located beneath the crests. One or more visibility strips are provided within the corrugations in a flank or root region, thus protecting the visibility strip from wear. Suitable visibility strips may be reflective or phosphorescent.

Abstract: An isolated antigen-binding protein characterised in that it is capable of binding specifically to human Arginase II (ARG2) and inhibiting the enzyme activity of human ARG2.

Abstract: The current document is directed to flow-presentation methods, and systems that incorporate these methods that address needs of many elderly users for a simpler, more intuitive computer-system interface that continuously presents user-interface features to users that allow users to access and use programs, rather than waiting for a user to actively search for, and select, program entries. The currently described flow-presentation methods are incorporated into computer systems to create platforms that provide a continuous flow of news, entertainment, weather, scheduled events, and other information, referred to as “content,” to a user's computer, such as a mobile computing device, including cell phones, tablets, and laptops, a desktop computer, or an interactive television. The flow of content may, in certain implementations, continuously repeat as a sequence or presented information, like a carousel.
