  • Publication number: 20180162944
    Abstract: The present disclosure provides monoclonal antibodies against protein programmed cell death 1 ligand (PD-L1), which can block the binding of PD-L1 to PD-1, and therefore block the inhibitory function of PD-L1 on PD-1 expressing T cells. The antibodies of disclosure provide very potent agents for the treatment of multiple cancers via modulating human immune function.

  • Publication number: 20170137613
    Abstract: A polyolefin composition includes a polyolefin substrate having incorporated therein a nucleating agent and a filler, wherein the composition exhibits an impact strength of >35 in-lb measured according to ASTM D4226, and a coefficient of linear thermal expansion of <4.5×10E-05 in/in/ft measured according to ASTM D696. The polyolefin composition may further include one or more of an ultraviolet light absorber, a hindered amine light stabilizer, an antioxidant, a colorant, a flame retardant, and an antimicrobial compound. The polyolefin compositions may be useful for construction articles for outdoor use, for instance house siding, cladding, soffit or roofing.

  • Publication number: 20160244591
    Abstract: Polyolefin compositions useful for construction articles for outdoor use, for instance house siding, cladding, soffit or roofing. The compositions comprise a polyolefin substrate which has incorporated therein one or more additives selected from the group consisting of a) one or more ultraviolet light absorbers, b) one or more hindered amine light stabilizers and c) one or more antioxidants. Advantageously, the polyolefin substrate also has incorporated therein d) one or more colorants, e) one or more fillers, f) one or more flame retardants and optionally g) one or more antimicrobial compounds. The compositions exhibit certain performance levels according to standard tests, for example impact strength of >35 in-lb per ASTM D4226, coefficient of linear thermal expansion of <4.

  • Patent number: 9036557
    Abstract: A wireless communication device communicates using a Long Term Evolution (LTE) wireless protocol and a different wireless protocol. The wireless device processes a first user input to direct a wireless transceiver to transmit and receive using the different wireless protocol and to direct a wireless paging receiver receive using the LTE wireless protocol. The transceiver then transmits and receives using the different wireless protocol, and the paging receiver receives pages using the LTE wireless protocol. The device processes a second user input to direct the transceiver to transmit and receive using the LTE wireless protocol, and the transceiver uses the LTE wireless protocol. In some examples, the device also processes the second user input to direct the paging receiver to receive other pages using the different wireless protocol, and the paging receiver receives the other pages using the different wireless protocol.

  • Patent number: 8699414
    Abstract: A wireless communication device receives a first user instruction to execute a first application requiring first wireless communications. The device selects a first wireless protocol for the first wireless communications based on the first application. A transceiver in the device exchanges the first wireless communications with a first wireless communication access node using the first wireless protocol and monitors a first paging channel of the first wireless protocol. A paging receiver monitors a second paging channel of a second wireless protocol in response to the application-based selection of the first wireless protocol.
