  • Publication number: 20180196924
    Abstract: A computer-implemented method of diagnosis of a patient comprises comparing a marker-print of a patient, wherein the marker-print comprises an N-value vector with each value in the vector indicative of a state of a biological marker of the patient, against a compendium of reference marker-prints, each reference marker-print having an associated biological condition, the reference marker-prints being stored in a marker-print database, to determine at least one reference marker-print having at least one matching value with the patient marker print. The method may comprise calculating, by a confidence module of the computer processor, a level of similarity between the patient marker-print and the at least one determined reference marker-print with the at least one matching value, thereby to provide an indication of a confidence level that the patient has the biological condition associated with the at least one determined reference marker-print having the at least one matching value.

  • Patent number: 9921105
    Abstract: The present invention discloses a spectrometer apparatus comprising a mobile device including an integrated camera, having a camera lens and an image sensor. The camera lens is located within a body of the mobile device that comprises a detachable housing coupled to the body of the mobile device. The detachable housing includes a first end and a second end opposed to the first end. The first end includes an optical input and the second end includes an opening that is substantially aligned with the camera lens. An optical spectrometer device is located within the housing and optically coupled to both the optical input at the first end of the housing and the camera lens at the second end of the housing. The optical spectrometer device receives a target image from the optical input and generates a spectral image that is received by the image sensor via the camera lens.

  • Publication number: 20180046771
    Abstract: Embodiments may provide the capability to identify genes or biological processes that may be targeted by other therapeutics in a group of individuals who are less likely to benefit from a specific targeted therapeutic. For example, a method may comprise receiving an indication of a biomarker or biological characteristic to be used to stratify patients into those who can benefit from a specified therapy or intervention versus those who have less or no benefit, computing an impact of the genomic state of at least one gene on survival or clinical progression of patients in the two groups, generating a ranking of a differential impact on survival for each of the at least one gene in the two groups, and based on the generated ranking, identifying genes whose state is more important to survival in the group who do not benefit from the therapy or intervention.

  • Publication number: 20170329914
    Abstract: Embodiments of the present invention may provide the capability to predict the metastasis of cancer in a patient from one tissue to another. In an embodiment, a computer-implemented method for predicting metastasis may comprise receiving an indication of at least one disrupted gene of the cancer, traversing data representing a gene-to-gene or protein-to-protein interaction network specific for a type of the cancer type from a position of the received gene in the network to a position of at least one gene involved in metastasis for a tissue type, organ or body part, determining at least one shortest path in the network between the received gene and the at least one gene involved in metastasis for the tissue type, organ or body part, generating a prediction of metastasis to the tissue type based on the at least one determined path, and generating an output display indicating a likelihood of spread of cancer to the tissue type, organ or body part.

  • Patent number: 9590001
    Abstract: A method of protecting a CMOS device within an integrated photonic semiconductor structure is provided. The method may include depositing a conformal layer of germanium over the CMOS device and an adjacent area to the CMOS device, depositing a conformal layer of dielectric hardmask over the germanium, and forming, using a mask level, a patterned layer of photoresist for covering the CMOS device and a photonic device formation region within the adjacent area. Openings are etched into areas of the deposited layer of silicon nitride not covered by the patterned photoresist, such that the areas are adjacent to the photonic device formation region. The germanium material is then etched from the conformal layer of germanium at a location underlying the etched openings for forming the photonic device at the photonic device formation region. The conformal layer of germanium deposited over the CMOS device protects the CMOS device.

  • Patent number: 9547125
    Abstract: A method of forming an integrated photonic semiconductor structure having a photodetector and a CMOS device may include forming the CMOS device on a first silicon-on-insulator region, forming a silicon optical waveguide on a second silicon-on-insulator region, and forming a shallow trench isolation (STI) region surrounding the silicon optical waveguide such that the shallow trench isolation electrically isolating the first and second silicon-on-insulator region. Within a first region of the STI region, a first germanium material is deposited adjacent a first side wall of the semiconductor optical waveguide. Within a second region of the STI region, a second germanium material is deposited adjacent a second side wall of the semiconductor optical waveguide, whereby the second side wall opposes the first side wall. The first and second germanium material form an active region that evanescently receives propagating optical signals from the first and second side wall of the semiconductor optical waveguide.
