  • Publication number: 20260195735
    Abstract: Methods and systems for digital hot wallet protection are provided. A payment channel is established via a Layer-2 network of a cryptocurrency blockchain for transferring a cryptocurrency balance from a first digital wallet of a service provider to a second digital wallet of a trusted entity over a plurality of commitment transactions. A transaction receipt for each commitment transaction is transmitted to the trusted entity via a secure communication channel previously established between the service provider and the trusted entity outside of the Layer-2 network. A transaction log of the service provider is modified so that it no longer represents the current transaction state of the payment channel. Responsive to detecting a breach of the first wallet, a transaction is broadcast to a Layer-1 network of the blockchain for transferring the total cryptocurrency balance from the first wallet to the second wallet.

  • Publication number: 20250326697
    Abstract: Systems and methods are provided for reaction bonded SiC-diamond (RBSiC-Diamond) composite with machinable features. A reaction bonded silicon carbide (SiC) based article may have a main structure formed using a first composite, and machinable areas formed using a second composite added to the main structures, to form a single continuous structure. The first composite may be silicon carbide (SiC) composite combined with at least one other element or compound (e.g., diamond), where the at least one other element or compound is selected to ensure meeting one or more performance criteria. Adding the other element or compound makes the main structure hard to machine or tool. The second composite may include silicon carbide (SiC) composite. The machinable areas may require machining or tooling, and the second composite may be easier to machine or tool than the first composite. The first composite is reaction bond to the second composite through infiltration bonding.

  • Publication number: 20250049904
    Abstract: The present application is directed to immunomodulatory compositions comprising invariant NKT cell (iNKT cell) agonist compounds that induce expansion of tissue resident memory T-cells (Trm Cells) in combination with an immune stimulator agent that enhances an immune response to a target antigen or a polynucleotide encoding the immune stimulator. The iNKT agonists are ?-GalCer analogue compounds modified at the 6 position of the galactose ring. The immune stimulator is an antigen or an mRNA encoding an antigen to create a vaccine formulation. These combinations are used in the treatment of infection or cancer in a subject, or to enrich the number of Trm cells in the liver of a subject.

  • Publication number: 20240247366
    Abstract: Disclosed herein are bonded diamond composites that may include a ceramic composite layer, a diamond film layer, and a silicon carbide bonding layer bonding the diamond film layer to the ceramic composite layer. Example ceramic composite layers disclosed herein include diamond particles within a silicon carbide matrix. Methods of making bonded diamond composites through infiltration bonding are disclosed herein. Example methods include exposing a ceramic preform to molten silicon such that the silicon infiltrates into and through the silicon preform to a diamond film interfaced with the ceramic preform. Example methods include reacting the silicon with the ceramic preform and the diamond film to form a silicon carbide bonding layer bonding the diamond film to the resulting ceramic composite layer.
