  • 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: 20150315281
    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.

  • 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.

  • Publication number: 20150065149
    Abstract: Systems and methods are disclosed for using structured communications in an observation platform with distributed traffic flow. A signal from a first mobile device is received at a second mobile device wherein the first mobile device and the second mobile devices act as a nodes in a first environment which comprises a plurality of nodes, wherein a first characteristic of the signal corresponds to an audible source and a second characteristic of the signal corresponds to information indicative of a geographic position of the first mobile device. Context information is derived, via the second mobile device, from the signal based on the first characteristic and/or the second characteristic. A third mobile device is determined, via the second mobile device, as a destination for the signal. The signal is relayed from the second mobile device to the third mobile device without relaying the signal to a central server computer system.
