Publication number: 20230209256Abstract: 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.Type: ApplicationFiled: February 17, 2023Publication date: June 29, 2023Applicants: The Board of Trustees of the Leland Stanford Junior University, University of LimerickInventors: Jonathan S.

Publication number: 20220214357Abstract: 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.Type: ApplicationFiled: May 4, 2020Publication date: July 7, 2022Applicant: University of LimerickInventors: Colum DUNNE, J.
