  • Publication number: 20250005564
    Abstract: Various embodiments of the present disclosure provide techniques for modifying a value of a credential-less exchange in near real time using a plurality of identifier mappings, member interfaces, and exchange modifiers. The techniques may include receiving an exchange request for executing a value-based exchange that is indicative of a universally unique ephemeral key (UUEK) and one or more request attributes. The techniques include identifying an exchange data object based on the UUEK and identifying a user exchange modifier for the exchange request based on the exchange data object and the request attributes. The techniques include generating a modified exchange value for the exchange request based on the user exchange modifier and providing an exchange authorization request to a member platform with the modified exchange value.

  • Patent number: 12159281
    Abstract: Various embodiments of the present disclosure provide techniques for facilitating a credential-less exchange over a network using a plurality of identifier mappings, member interfaces, and security code tuples that are tailored to an ephemeral key. The techniques may include receiving a secured interaction request and issuing or enabling a previously issued universally unique ephemeral key (UUEK) in response to the secured interaction request. The techniques may include validating a user, instrument, or UUEK and, in response, storing a secured event for the user, instrument, or UUEK and providing a secured interaction response indicative of the secured event. The techniques may include subsequently receiving an exchange request for executing a value-based exchange using the UUEK and facilitating the exchange request based at least in part on the secured event.

  • Publication number: 20240271092
    Abstract: This disclosure relates to compositions and methods of reversing senescence in T cells by interrupting vasoactive intestinal peptide (VIP) signalling and/or inhibiting phosphatidylinositol-3-kinase (PI3 kinase) inhibitor signalling and uses in managing cancer and chronic viral infections. In certain embodiments, the disclosure contemplates methods of reversing T cell senescence by mixing T cell in vitro with an agent that prevents VIP from interacting with VIP receptors and/or a PI3 Kinase inhibitor. In certain embodiments, the disclosure contemplates the expansion of senescent T cells by mixing with a PI3 kinase inhibitor, an agent that block VIP and VIP receptor signalling, a VIP degrading enzyme, and combinations thereof.
