Abstract: A method of renting rentable items using NFTs receives a request from an owner to list a rentable item for rent, causes a distributed ledger system to mint an inheritable rental NFT, and assign the rental NFT to the owner. The method lists the item for rent, receives a request from a renter to rent the item for a first set of time durations, and causes the distributed ledger system to mint a first set of child rental NFTs, where each child rental NFT is associated with a time duration in the first set of time durations, assign the first set of child rental NFTs to the renter, mint a second set of one or more child rental NFTs for the rentable item for time durations other than the first set of time durations, assign the second set of child rental NFTs to the owner, and burn the rental NFT.

Abstract: A Bluetooth Low Energy (BLE) mesh-based provisioning control method and system, and an electronic device. The method includes: the provisioner completes, within one interval scheduling cycle based on a preset ratio of effective transmission time to interval, interactive transmission of at least three data packets sent by the server; during provisioning between the provisioner and the to-be-connected device, the provisioner obtains current wireless access point information; the provisioner determines a target hopping channel value based on the current wireless access point information; after the to-be-connected device receives a connection request sent by the provisioner and sets the target hopping channel value as a to-be-connected device hopping value, the provisioner controls the to-be-connected device to hop at a frequency corresponding to the to-be-connected device hopping value to complete interaction of provisioning data packets.

Abstract: A method of validating the ownership of a cryptocurrency based on the user's biometric information is provided. The user's accounts are generated based on their biometric information. The biometric information of the users is stored in their accounts as their original biometric seeds. The users generate additional user-generated biometric seeds from portions of their original biometric seeds. The users use capsules as valued carriers. The users combine the capsules and their user-generated biometric seeds to generate cryptocurrencies with the same value as the capsules. When a cryptocurrency is transferred from a first owner to a second owner, the second owner decomposes the cryptocurrency to get a capsule with the same value as the cryptocurrency. The second user combines the capsule of the second user's user generated biometric seeds to generate a cryptocurrency.

Abstract: A power transmission line photonics-electronics converged long-distance monitoring device (10) and method.

Abstract: In alternative embodiments, provided are compositions, including products of manufacture and kits, and methods, for inhibiting the ability of neutrophils, or polymorphonuclear leukocytes (PMNs), to release reactive oxygen species (ROS), thus also inhibiting or ameliorating neutrophil (PMN) contribution to an inflammatory response, thus also treating, ameliorating or preventing neutrophil (PMN)-meditated inflammatory-related pathologies such as acute respiratory distress syndrome (ARDS), including ARDS caused by a viral infection such as COVID-19.
