Abstract: Disclosed is a method and system for modifying content stored in a blockchain. The method comprises identifying an old block of the blockchain comprising undesired data in a transaction of the old block. An updated block may be created by correcting the transaction of the old block. A new block hash may be determined for the updated block. Corrected form of the transaction may be submitted, as a new transaction, along with the new block hash and the difference between the new block hash and hash of the old block. Miners may be allowed to mine the corrected form of the transaction, along with other new transactions. The other new transactions may be mined, based on a consensus of users of the blockchain, into a new block connected to a tip of the blockchain, and the old block may be edited to introduce the corrected form of the transaction.

Abstract: Disclosed is a system for facilitating identification of a sound generation device used for creating an audio clip. The audio clip is created by combining one or more audio signal chains corresponding to at least one sound generation device. Each audio signal chain is embedded with an audio signature having frequency beyond a frequency range of human hearing. The audio signature comprises a unique identification number corresponding to the sound generation device. The system upon receipt of the audio clip, identifies the audio signature associated with each audio signal chain from the one or more audio signal chains. Subsequently, the system analyses the audio signature to identify the sound generation device.

Abstract: Disclosed is a system for authenticating a sender of an E-mail to be sent over a network. The system assigns a public key and a private key to each of a plurality of E-mail addresses and thereby stores a plurality of public key over a blockchain. The system further sends an E-mail to a recipient over a network by creating a header, in the E-mail, storing content that needs to be sent to a recipient. The system further analyzes the header to determine whether the E-mail address is present on the blockchain. If the E-mail address is present, the system further retrieves a public key, of the plurality of public keys, corresponding to the E-mail address from the blockchain. The system further authenticates the sender of the E-mail upon verifying the signature, used to sign the content, by using the public key retrieved for the E-mail address from the blockchain.

Abstract: Disclosed is a system for authenticating a caller. The system assigns a public key and a private key to each Caller Identifications (CLID), of a plurality of CLIDs pertaining to a plurality of mobile telephony numbers. The system stores a plurality of CLIDs and a plurality of public keys, associated to the plurality of CLIDs, over a blockchain formed by the plurality of telephony service providers. The system sends a Multi Data Message Format (MDMF) message to a telephony service provider of a callee. The system analyzes the MDMF message to determine whether the CLID is present over the blockchain. The system enables the telephony service provider of the callee to retrieve a public key, of the plurality of public keys, corresponding to the CLID from the blockchain, when the CLID is present on the blockchain. The system authenticates the caller upon verifying the signature by using the public key.

Abstract: A system for authenticating a sender of an Electronic message transmitted over a telephony network assigns a public key and a private key to each of a plurality of mobile telephony numbers and thereby stores a plurality of public key over a blockchain. The public key and the private key are assigned upon registration of a mobile telephony number with a telephony service provider The Electronic message is sent to a recipient over the telephony network by creating a header, in the message, storing content that needs to be sent to a recipient. The system further analyzes the header to determine whether the mobile telephony number is present on the blockchain. If so the system further retrieves a public key corresponding to the mobile telephony number from the blockchain. The sender of the mobile telephony number is authenticated upon verifying the signature by using the public key from the blockchain.

Abstract: The present invention provides a new method for producing Engineered Heart Muscle (EHM) under chemically fully defined conditions and compounds all compatible with GMP regulations. The resulting human myocardium generates force and shows typical heart muscle properties.

Abstract: In some examples of the disclosure, a parameter override mechanism may include a variable length configuration data table with entries for specific models of memory devices. The configuration data table entries may include override parameters for different memory devices and may be dynamically updated with new entries and modifications of existing entries. The parameter override mechanism may be configured to automatically detect a model of memory device and select a corresponding configuration data table entry based on the detected model of memory device or restrict the use of a configuration data table entry based on the detected model of memory device.

Abstract: A position sensing device for sensing an upper limit position and a lower limit position of a hoisting line for raising and lowering a door leaf of an animal enclosure, the position sensing device comprising a hoisting line pathway for a hoisting line to raise and lower a door leaf of an animal enclosure, an actuator arm moveable between a first position and a second position, and a proximity switch having a first state corresponding to the actuator arm being in the first position and a second state corresponding to the actuator arm being in the second position.

Abstract: The present invention is directed to a method for producing bioengineered heart muscle (BHM) from pluripotent stem cells, generally comprising the steps of inducing mesoderm differentiation, cardiac differentiation, and cardiac maturation by directed tissue formation. The method is a robust, serum-free and reproducible way to produce BHM for multiple applications, and is applicable to multiple pluripotent stem cell lines. The present invention is also directed to the BHM produced by the method disclosed herein, as well as to uses of said BHM in pharmacologic and toxicity screenings, and its use in medicine.

Abstract: A system and method for structuring an online auction when a reserve price is not met are described. In an online auction, bidding activity is analyzed over a duration to determine whether there are multiple active bidders for the auction and whether the reserve price for the auction is met after a designated period of time. In response to making that determination, the bidder interface for a sole active bidder on the auction can be automatically updated to include a notification that the bid has not met the reserve price and an option to place a new bid on the item so that the auction is successful and does not end with no bids meeting the reserve.

Abstract: Examples described herein pertain generally to network computer systems, and more specifically, to network computer systems for evaluating contingency based outcomes for network transactions.
