  • Publication number: 20160068604
    Abstract: Human antibodies, preferably recombinant human antibodies, both humanized and chimeric, which specifically bind to human OX40 are disclosed. Preferred antibodies have high affinity for OX40 receptor and activate the receptor in vitro and in vivo. The antibody can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, are useful for modulating receptor activity, e.g., in a human subject suffering from a disorder in which OX40 activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies are provided, and methods of synthesizing the recombinant human antibodies, are also provided.

    Abstract: A system and method for maximizing displaying of trajectory elements in an edit area of a navigational display are disclosed. In one embodiment, navigational display parameters are obtained from a cockpit display system. Further, flight plan information is obtained from a flight management system (FMS). Furthermore, a portion of the flight plan information which lies within the edit area of the navigation display is dynamically determined using the navigational display parameters. In addition, a display buffer is dynamically populated with only the determined portion of the flight plan information. Moreover, any needed data that is in the determined portion of the flight plan information is dynamically refreshed in the display buffer. Also, the flight plan information is dynamically displayed on the edit area of the navigation display using the refreshed and populated flight plan information and the needed data.

  • Publication number: 20150328586
    Abstract: A method and system for mitigating a urea deposit within an SCR system that includes determining a mass of an accumulated urea deposit present within the SCR catalyst and SCR piping, comparing the mass of the accumulated urea deposit with a deposit upper threshold limit, and initiating an SCR regeneration event when the mass of the accumulated urea deposit is greater than the deposit upper threshold limit. The method further includes determining an amount of NH3 passing through the SCR catalyst downstream of the urea deposit, comparing the amount of NH3 passing through the SCR catalyst with an NH3 regeneration threshold limit, and terminating the SCR regeneration event when the level of NH3 passing through the SCR catalyst is less than the SCR NH3 regeneration threshold.

  • Publication number: 20150285996
    Abstract: The present invention relates to an integrated photonic device comprising a photonic substrate, and an integrated waveguide provided in or on this substrate. The waveguide is adapted for conducting radiation of a predetermined wavelength. The device further comprises a sub-wavelength grating optically connected to the waveguide, which provides a first periodic variation of the refractive index in at least one first spatial direction. The device also comprises a diffracting grating arranged over the sub-wavelength grating for coupling radiation of the predetermined wavelength in and/or out of the integrated waveguide via the sub-wavelength grating. The diffracting grating provides a second periodic variation of the refractive index in at least one second spatial direction. The first periodic variation has a first pitch that is less than half of the predetermined wavelength, while the second periodic variation has a second pitch that is at least half of the predetermined wavelength.
