  • Patent number: 12273725
    Abstract: A mobile device performs authentication with blinded tokens and swaps its international mobile subscriber identity (IMSI) value. For authentication with blinded tokens, the mobile device generates a blinded token and provides it to a server to encrypt. To redeem the token, the mobile device unblinds the encrypted blinded token and provides it to the server along with a public key. To complete authentication, the mobile device receives, from the server, a nonce encrypted with the public key and decrypts the nonce with a private key. For swapping its IMSI value, the mobile device retrieves two eSIM profiles with corresponding IMSI values and configures the first of the two profiles as active. In response to a trigger, the mobile device changes the active profile from the first to the second, swaps the first IMSI value with a new IMSI value, and changes the active profile back to the first profile.

  • Publication number: 20220054531
    Abstract: Methods are presented for treating cancers and hematopoietic stem cell disorders, comprising administering to a subject with a cancer or hematopoietic stem cell disorder who is receiving a treatment regimen, a heparin derivative capable of inhibiting, reducing, abrogating or otherwise interfering with the binding of CXCL12 to CXCR4, wherein the cancer or hematopoietic stem cell disorder is one in which interaction of CXCL12 with CXCR4 privileges the cancer or disordered HSCs against therapeutic intervention. In preferred embodiments, the heparin derivative is a substantially 2-O, 3-O-desulfated heparin derivative.

  • Patent number: 11055156
    Abstract: A method and related system to concurrently process a temporal message stream. The method comprises obtaining messages of a message stream, each message having an associated timestamp. The method further comprises storing each message in at least one of a plurality of queues, wherein the messages of each queue are ordered based on their timestamp such that a message with the earliest timestamp is positioned at the front of the queue. The method then comprises controlling retrieval of the target message from the front of a target queue based on a timing difference between the timestamp of the message and the timestamps of the front message of each of the other queues of the plurality of queues.

  • Patent number: 10905661
    Abstract: This application relates to methods and compositions for the administration of disulfiram (DSF) and heavy metals zinc and copper for the treatment and prevention of medical conditions, such as cancer. DSF and copper as well as DSF and zinc form active complexes that have been shown to be effective in the treatment of cancers. However, as described herein, DSF is incompatible with either copper or zinc for simultaneous oral administration. Included herein are improved methods and oral dosage forms comprising DSF and copper and DSF and zinc in fixed dose combinations that are configured to temporally stagger release of either DSF and copper or DSF and zinc after ingestion.
