  • Publication number: 20240145625
    Abstract: A device including an activated p-type layer comprising a III-Nitride based Mg-doped layer grown by vapor phase deposition or a growth method different from MBE. The p-type layer is activated through a sidewall of the p-type layer after the removal of defects from the sidewall thereby increasing a hole concentration in the p-type layer. In one or more examples, the device includes an active region between a first n-type layer and the p-type layer; a second n-type layer on the p-type layer; and a tunnel junction between the second n-type layer and the p-type layer, and the activated p-type layer has a hole concentration characterized by a current density of at least 100 Amps per centimeter square flowing between the first n-type layer and the second n-type layer in response to a voltage of 4 volts or less applied across the first n-type layer and the second n-type layer.

  • Publication number: 20240146188
    Abstract: A multi-phase hybrid power converter architecture which provides high efficiency, high power density and high conversion ratios for non-isolated DC to DC power conversion. Hybrid converters are described in which a switched-capacitor network is interoperably merged with a switched-inductor network having multiple inductors, resulting in a circuit with reduced component count and in which soft-charging of the capacitors is performed. Multi-phase switching is utilized and includes a freewheeling state for output voltage regulation in which inductor current ramps down. The SC converter can be configured to provide various conversion ratios, such as 4-to-1, 6-to-1 and 8-to-1, and optimized for the needs of specific application.

  • Publication number: 20240138597
    Abstract: A smart retail product shelf liner called ‘MOOCA’ to detect product loads on its surface. The liner preferably has an origami like structure whose properties (e.g., angles, unit size, material) are adjusted to make the liner configurable for different sizes, load ranges, and product packaging. The smart liner is well suited for autonomous checkout systems. MOOCA is an origami-inspired low-cost configurable surface structure having conductive threads and copper wires integrated into the origami structure to detect and recognize product loads and thus to detect when products are either picked-up, or put-down, upon the smart MOOCA liner of the shelf.

  • Publication number: 20240142474
    Abstract: Opsin proteins are GPCRs known for light perception. Here it is shown that these receptors are also expressed in chemosensory cells and function as chemosensory receptors activated by a range of molecules, including tastants such as theobromine, for which a receptor has not previously been known. Provided are novel assay systems for assessing chemosensory opsin activation by chemical ligands. By these assays, novel ligands of chemosensory opsins may be identified, the chemosensory properties of molecules may be evaluated; and the modulation of chemosensory properties by modifications or modulators may be tested.

  • Publication number: 20240142436
    Abstract: Candidate cancer antigens are identified using transposable elements. Differential expression levels are determined for proteins using baseline expression levels (using measurements of healthy tissue) and tumor expression levels (using measurements of tumor tissue). Protein(s) having a differential expression level greater than a threshold are selected. Cancer vaccine(s) are generated for the selected cancer antigens (s). Particular cancer vaccine(s) are selected for a patient based on differential expression levels for proteins using baseline expression levels of the patient and tumor expression levels of the patient. A vaccine for protein(s) having a differential expression level greater than a threshold can be selected. A microarray can be used for the measurements of the patient. A first array of probes can hybridize to RNA from transposable elements. A second array of probes can hybridize to RNA of different MHC haplotypes. A third array of probes can hybridize to RNA of different APOBEC genotypes.

  • Patent number: 11970572
    Abstract: Embodiments of the presently disclosed technology provide a synergistic combination of a conjugated open-shell donor-acceptor polymer with a carbon-based compound (e.g., reduced graphene oxide) to produce a composite electrode material which demonstrates state-of-the-art capacitance and potential window, with excellent kinetics and cycle life. The conjugated open-shell donor-acceptor polymer may comprise a plurality of alternating electron-rich monomers (i.e., donors) and electron-deficient monomers (i.e., acceptors) bonded together via a conjugated backbone. The conjugated backbone may comprise a connection of n-orbitals of the plurality of monomers in alternating single and double bonds that facilitates unpaired electron delocalization—thereby stabilizing charge for the polymer. The carbon-based compound of the composite electrode material may provide porous, conductive scaffolds for the composite electrode material, resulting in electrodes scalable to microns-thick films with fast kinetics.

  • Patent number: 11972408
    Abstract: A method may include embedding, in a hidden layer and/or an output layer of a first machine learning model, a first digital watermark. The first digital watermark may correspond to input samples altering the low probabilistic regions of an activation map associated with the hidden layer of the first machine learning model. Alternatively, the first digital watermark may correspond to input samples rarely encountered by the first machine learning model. The first digital watermark may be embedded in the first machine learning model by at least training, based on training data including the input samples, the first machine learning model. A second machine learning model may be determined to be a duplicate of the first machine learning model based on a comparison of the first digital watermark embedded in the first machine learning model and a second digital watermark extracted from the second machine learning model.
