Abstract: An apparatus, system, and method for magnetic separation of cells are disclosed. By combining inkjet printing technology and magnetic labeling of cells, accurate cell counts are obtained using an optical microscope. Mouse CD4+ lymphocytes are attached to micron sized magnetic beads and printed through a modified, commercial inkjet printer. The labeled cells are then attached to a glass slide covering a permanent magnet. Cell counts can be obtained by use of regular and inverted optical microscopes and imaging software. The magnetically-labeled beads are collected for evaluation on a modified polymer coupon that is placed in front of a permanent magnet and the unlabeled cells fall into an excess container. Flow cytometry results verify the presence of the CD4+ protein on the LBRM-33 lymphocytes membrane. Protein-specific attachment of magnetic microspheres to the lymphocytes is utilized for sorting CD4+ lymphocytes.

Abstract: A system and method for communication failover is disclosed. The disclosed embodiments allow voice communications (both inbound and outbound) that are normally carried by VoIP to be automatically switched over to a PSTN in the event of a failure of the VoIP communication network.

Abstract: Macromolecular imprinted silica particles (“MIP”) in the presence of polymer grafted carbon black are disclosed. The disclosed molecular imprinted beads can detect disease in body fluids. For the silica gel matrix, tetraethyl orthosilicate (TEOS) was used as the backbone monomer and 3-aminopropy/triethoxysilane (APS) as a functional monomer. Carbon black was added to the sol-gel process, yielding black silica particles. Furthermore, sodium dodecyl sulfate (SDS) was used as a structure-directing agent to increase network diffusion of the template. A total of 16 MIPs were synthetized in parallel with variables that evaluate the role of key reactants in the synthesis procedure. Agglomeration tests were performed with all 16 MIPs in the presence of their template, alongside their respective controls using only phosphate buffered saline (“PBS”). Each of the MIPs was evaluated using a novel device capable of simultaneously measuring up to four samples for near infrared transmission.

Abstract: An inkjet printing method, system, and computer-usable tangible storage device to print cells and biomaterials for three-dimensional cellular scaffolds and engineered skin grafts are disclosed. The process simultaneously deposits living cells, nutrients, growth factors, therapeutic drugs along with biomaterial scaffolds at the right time and location. This technology can also be used for the microvasculature fabrication using appropriate human microvascular endothelial cells and fibrin to form the microvasculature. When printing human microvascular endothelial cells in conjunction with the fibrin, the cells aligned themselves inside the channels and proliferated to form confluent linings. The 3D tubular structure was also found in the printed patterns. Simultaneously printing biological materials to form a three-dimensional cellular scaffold promotes human microvascular endothelial cell proliferation and microvasculature formation.

Abstract: Based on information used by the external system to identify a target user, the external system generates a target user hash identifier that is communicated to the social networking system along with a message. Using information from user profiles maintained by the social networking system, the social networking system generates hash identifiers for its users and compares the target user hash identifier to the generated hash identifiers hash identifiers for social networking system users are generated. The social networking system sends the message to a user associated with a hash identifier generated from user profile information that matches the target user hash identifier. Hence, an external application may communicate with social networking system users without accessing access information about the users maintained by the social networking system.

Abstract: An entity provides a competitive block list for one or more of its objects in a social networking system. The competitive block list identifies advertisers or other entities prevented from targeting advertisements based on connections between users and objects of the entity. If a later received advertisement is targeted based on a connection between a user and an object of the entity, the social networking system determines whether the advertiser associated with the advertisement is included on the competitive block list. If the competitive block list includes the advertiser, the advertisement is determined not to be valid, and not presented to users. Otherwise, the advertisement is determined to be valid, and may be presented to users thereafter.

Abstract: The present invention is a light weight, rigid, carrying handle that allows a single user to safely and securely transport multiple cylinders with one hand. The carrying handle consists of a rectangular grip plate, a tab at each end of the grip plate extending away from the grip plate about perpendicular to the surface of the grip plate, and a grip guard on each side of the grip plate also extending away from the grip plate about perpendicular to the surface of the grip plate. The tabs and grip guards all preferably extend in the same direction away from a inner surface of the carrying handle. The tabs are configured thin such that it can be inserted into and through an opening in a cylinder collar bracket.

Abstract: A planetary carrier includes a side plate having a front face and a shaft journal which is arranged on the front face of the side plate. A bearing seating is formed on an outer circumferential surface of the shaft journal on a front-face-proximal end of the shaft journal. The planetary carrier has an annular groove directly adjacent to the bearing seating in coaxial relationship to the shaft journal and undercutting the front face and the outer circumferential surface.

Abstract: In one embodiment, the social networking selects a display item to display to a viewing user based on information about the viewing user and a display sequence tree associated with an ad campaign. The display items include advertisements, sponsored stories, and content objects created by users. The information about the user includes the viewing user's interactions, the viewing user's demographic information, and the viewing user's inferred characteristics. A display sequence tree associated with an ad campaign is a hierarchical arrangement of nodes that correspond to display items and represent possible sequences of display items. An ad campaign includes at least one request for a display item.

Abstract: A social networking system maintains profile information about a subject user and about a viewing user. The viewing user requests a page of information about the subject user (e.g., a profile page) from the social networking system. The social networking system determines a set of interests or other information about the subject user based on the subject user's profile information. One or more ads are selected based at least in part on the set of determined interests or other information about the subject user. The profile page of the subject user is generated, where the profile page comprises profile information about the subject user along with the selected ads. The profile page of the subject user is then sent to the viewing user for display.
