The compound may comprise a non-ionic acid labile surfactant. The compound may be used to facilitate solubilization of proteins and other molecules in an aqueous environment.

Abstract: A reconfigurable seating system may include a bank of seating units disposed in rows. Associated chairs may be arranged in the seating units, supported on support beams by chair brackets. The reconfigurable seating systems may be installed on flat floors or sloped floors and may be arranged in linear-rows and/or arched-row configurations.

Abstract: Systems, methods, and computer-readable media for managing collaboration on a virtual work of art between multiple electronic devices are provided. A first graphical display system of a first device may generate an input command in response to receiving user information through a user interface of the first device, and may then share this input command with a second graphical display system of a second device. The first graphical display system may process the shared input command to generate pixel array data in a canvas of the first device while the second graphical display system may process the shared input command to generate pixel array data in a canvas of the second device. By sharing input commands rather than pixel array data, system latency may be reduced. Despite operating on the same artwork, the user interfaces and graphical processing capabilities of each device may vary, thereby providing the user greater expressiveness.

Abstract: A new user interface and display system for a video display device with a touch screen makes it possible to peek at, that is view briefly, a selected video content while watching other content. During a video peek, video from a second video source will be seen to partially displace and temporarily replace a portion of a video presently being viewed. Selection of the other video sources can be controlled, for example, by swiping with one, two, three or four finger tips and by swiping inwardly from any one of the four edges of a video display. Moreover, the video presently being viewed can be interchanged with the video being peeked at.

Abstract: According to some aspects, a tug and barge arrangement is provided that is configured with an articulated conduit system for transferring fluid between the tug and the barge. In some embodiments, an articulated conduit system is provided that comprises a plurality of conduits fluidically interconnected by rotatable joints configured to permit positional alterations of the fluid conduits that result from differential movement between a tug and barge.

Abstract: The present invention extends to methods, systems, and computer program products for linking diagnostic visualizations to regions of application code. Diagnostic visualizations emitted during execution of an application are displayed. The diagnostic visualizations partially represent the abstract objective of the application (e.g., as envisioned by a developer). Diagnostic data for at least one of a plurality of components is displayed. The diagnostic data indicates the performance of the at least one of the plurality of components during execution of the application. The displayed one or more diagnostic visualizations and the displayed diagnostic data is correlated to link the one or more diagnostic visualizations to the at least one of the plurality of components. Linking the one or more diagnostic visualizations to the at least one of the plurality of components can better indicate how the application's behavior reconciles the abstract objective.

Abstract: Rocker style chairs and rocker style chairs with pivoting seats are provided along with modular components for use within rocker style chairs and parts for assembling within the modular components. The related components and chair assemblies minimize manufacturing time, maximize material usage and decrease related installation time. The related rocker style chairs may provide comfort to chair occupants and minimize noise during related chair component motion.

Abstract: According to some aspects, a tug and barge arrangement is provided that is configured with an articulated conduit system for transferring a fuel gas (e.g., natural gas) between the tug and barge. In some embodiments, an articulated conduit system is provided that comprises a plurality of conduits fluidically interconnected by rotatable joints configured to permit positional alterations of the fluid conduits that result from differential movement between a tug and barge, such as relative vertical displacement between the tug and barge and/or relative rotation between the tug and barge about a forward-aft axis of the tug.

Abstract: The telescopic seating systems, and foldable chairs and related components for use within telescopic seating systems, of the present disclosure may incorporate occupant support elements within a space between a top surface of a seat frame structure and a bottom surface of the seat frame structure. Springs may be attached to the top surface of the chair frame structure and configured to extend into the space. Alternatively, or additionally, a chair cushion may extend into the space.

Abstract: This is directed to a preview application for displaying several documents simultaneously in a single window, where the several documents are displayed as books. To view the pages of a document, the preview application can open the book and display the pages of the document (e.g., in a one or two-dimensional array). A user can also search for particular terms within the several documents. In response to a search, the preview application can filter the pages of the several documents and only display those pages that include the search terms. The displayed pages can be ordered in any suitable manner, including for example by search rank.
