  • Publication number: 20230209256
    Abstract: The present embodiments generally relate to enabling participants in an online gathering with networked audio to use a cancelling auralizer at their respective locations to create a common acoustic space or set of acoustic spaces shared among subgroups of participants. For example, there are a set of network connected nodes, and the nodes can contain speakers and microphones, as well as participants and node mixing-processing blocks. The node mixing-processing blocks generate and manipulate signals for playback over the node loudspeakers and for distribution to and from the network. This processing can include cancellation of loudspeaker signals from the microphone signals and auralization of signals according to control parameters that are developed locally and from the network.

  • Patent number: 11492454
    Abstract: A material susceptible to dielectric heating has a base polymeric thermoplastic material (1) and a dielectric heating susceptor (2, 3) which increases susceptibility to heating by irradiation with electromagnetic, for example RF or microwave, radiation. The dielectric heating susceptor has a polymeric material (2) such as PVDF which is different from the base polymeric material and has a higher dielectric loss factor than the base polymeric material. The dielectric heating susceptor also comprises electrically polarisable entities such as carbon black dispersed within the base polymeric material without forming a conductive network. The two susceptor materials in combination with the base polymer are particularly effective together at improving susceptibility to electromagnetic radiation heating of the whole material.

  • Publication number: 20220214357
    Abstract: The Applicant has discovered a cytokine profile that can accurately distinguish between ulcerative colitis (UC) and Crohn's disease (CD) in a subject having, or having symptoms of, inflammatory bowel disease (IBD). The profile of ulcerative colitis is increased IL-10 levels (compared with a reference IL-10 level, and decreased IL-23 levels (compared with a reference IL-23 level). The cytokine profile can be detected at a protein or genomic level, and is generally determined from a peripheral blood sample (i.e. a blood fraction such as serum, plasma, or blood cells such as peripheral blood mononuclear cells). Distinguishing between UC and CD in a subject with IBD allows a clinician prescribe a suitable therapeutic regime for the subject using a non-invasive blood test, and avoiding the need for scoping or tissue biopsy, which are undesirable for the subject. The cytokine profile can also be used to monitor a therapeutic regime for effectiveness.

  • Patent number: 11058985
    Abstract: A method of separating acetylene from a gas mixture comprising acetylene is provided. The method involves the use of a hybrid porous material with an affinity for acetylene adsorption. The hybrid porous material comprises a three-dimensional structure of metal species (M) and first and second linker groups (L1 and L2), wherein the metal species (M) are linked together in a first and second direction by first linker groups (L1) and are linked together in a third direction by second linker groups (L2) to form the three-dimensional structure. The hybrid porous materials may have a high selectivity for acetylene and/or a high capacity for acetylene adsorption. The method may be particularly useful for the purification of ethylene gas contaminated with acetylene during an ethylene production/purification process. The method may be particularly useful for the large scale separation of acetylene from other gases such as ethylene and carbon dioxide, during an acetylene production/purification process.
