Abstract: The present disclosure relates to compounds of Formula (Ia) and (Ib): or a pharmaceutically acceptable salt thereof, which are useful in the treatment of an HIV infection in heavily treatment-experienced patients with multidrug resistant HIV infection.

Abstract: A method for forming a graphene-reinforced polymer matrix composite is disclosed. The method includes distributing graphite microparticles into a molten thermoplastic polymer phase; and applying a succession of shear strain events to the molten polymer phase so that the molten polymer phase exfoliates the graphite successively with each event until at least 50% of the graphite is exfoliated to form a distribution in the molten polymer phase of single- and multi-layer graphene nanoparticles less than 50 nanometers thick along the c-axis direction.

Abstract: A method and a system for providing an alternative fulfillment for a buyer's unfulfilled order are described. The system has an order fulfillment issue detection module, an alternative fulfillment qualification module, a replacement item matching module, and a replacement item order module. The order fulfillment issue detection module detects a fulfillment delay of an item in an order placed in an online marketplace. The alternative fulfillment qualification module determines whether the fulfillment delay qualifies for an alternative fulfillment order. The replacement matching module determines a replacement item for the item. The replacement item order module cancels the order and replaces the order with the alternative fulfillment order for the replacement item.

Abstract: A flexible shipping delivery system has an online marketplace interface, a client interface, a shipping carrier interface, and a flexible shipping delivery engine. The online marketplace interface communicates with an online marketplace application. The client interface communicates with a client that places an order for an item on the online marketplace application. The client interface receives a shipping delivery preference of a user of the client. The shipping carrier interface communicates with a shipping carrier server. The shipping carrier server provides a tracking shipping status of the item. The flexible shipping delivery engine adjusts a delivery option of the item based on the tracking shipping status of the item and the shipping delivery preference.

Abstract: In one embodiment, a sheet separator includes a bias that resiliently biases a first sheet engaging surface in a direction away from a second surface, wherein the second surface engages the edge of sheets upon movement of the first surface. In one embodiment, a method applies opposite forces to a stack of sheets, wherein one of the opposite forces varies based upon a characteristic of the sheets.

Abstract: A system to assist sellers create automated sales for products and services the seller has made available for purchase. The embodiments include receiving sales information that includes data item information that identifies a plurality of data items that are offered for purchase by a seller on a network-based marketplace. The system provides means for scheduling a sale based on the sale information, the sale to begin at a first time and end at a second time, the first time associated with a reduction of a plurality of prices to a plurality of discounted prices. The plurality of prices respectively associated with the plurality of data items. The plurality of discounted prices respectively associated with the plurality of data items and the second time associated with a restoration of the plurality of prices for the plurality of data items.

Abstract: A media loading and separation system includes a spring pick block with an inclined surface having a lower end; an indentation, formed near the lower end of the inclined surface, having a substantially vertical surface; and a spring arm movably disposed in response to a media stack with respect to the inclined surface between rearward and forward positions. The media separation system can also include a corner media separator to engage a corner of the media stack.
