A system for breakage early warning of high-voltage transmission lines based on acoustic prints, including a data acquisition unit, an edge processing unit, a cloud server, a warning execution unit, and a communication unit. The data acquisition unit is configured to collect environmental information of a high-voltage transmission tower in real time through a multimodal sensing device. The edge processing unit includes an adaptive filtering module configured to eliminate wind noise interference in the environmental information and compensate for frequency response deviation. The cloud server can generate a warning instruction based on the environmental information. The warning execution unit can perform warning and alarming actions based on the warning instruction. The communication unit is configured to enable data and information transmission among the units. A method implemented by such system is also provided.

Implementations of this specification include receiving a synchronization request from a light-weight node of the blockchain network including an identity of the light-weight node; identifying one or more permissions associated with the identity of the light-weight node; determining an original world state structure associated with the block height and including a plurality of account records; identifying based on the one or more permissions, a subset of the plurality of account records that are authorized for access by the light-weight node; generating an isolated world state structure based on the original world state data structure including only the subset of the plurality of account records that are authorized for access by the light-weight node; sending a response to the light-weight node that includes the isolated world state data structure.

Data isolation in blockchain networks

Implementations of the present specification include receiving, by a blockchain node in the blockchain network, a request to read a particular block of the blockchain, wherein the request is received from a light-weight node of the blockchain network and includes an identity of the light-weight node, and wherein the particular block includes an original Merkle tree associated with the particular block; identifying, by the blockchain node, permissions associated with the identity of the light-weight node; generating, by the blockchain node, an isolated Merkle tree based on the original Merkle tree included in the block, the isolated Merkle tree including only transactions from the original Merkle tree that are determined to be accessible by the light-weight node based on the identified permissions, wherein the isolated Merkle tree is consistent with the original Merkle tree; and sending, by the blockchain node, a response to the light-weight node including the isolated Merkle tree.

Data isolation in a blockchain network

Implementations of the present disclosure include initializing a nonce table comprising a plurality of nonce slots, each nonce slot being associated with a nonce index and a status, and storing a respective nonce value; receiving a request for a nonce value from an application, and in response, requesting a nonce value from the nonce table; receiving a nonce value in response to the request, a status of a nonce slot corresponding to the nonce value being set to occupied; and in response to a transaction using the nonce value being one of successful and failed, executing one of: releasing the nonce value within the nonce slot and setting the status to unoccupied, if the transaction is successful, and setting the status to unoccupied, if the transaction failed.

Utilizing nonce table to resolve concurrent blockchain transaction failure

The present invention discloses a core-shell structure supported tungsten composite catalyst and a preparation method and use thereof. Most of the existing synthesis methods of the main ring of quinolone drugs have the defects of many synthesis steps, cumbersome operation, large amount of three wastes, higher costs and the like. The present invention prepares a magnetic separable core-shell supported tungsten composite catalyst, WO/SiO/FeO, by preparing FeOcolloid and SiO/FeOcomposite nano-particles. This magnetic separable core-shell supported tungsten composite catalyst, WO/SiO/FeO, is used to catalyze and synthesize quinolone compounds. The present invention provides an efficient preparation method of quinolone compounds using a catalyst which can be recovered by magnetic separation and recycled. The catalyst prepared by the present invention can be reused in the preparation of quinolone compounds and still retains the original activity without deactivation, which not only greatly improves the production efficiency, but also reduces the environmental pollution.

The present invention describes a novel synthetic method for preparing the key intermediate 2,6,10-trimethyl-1,1-dialkoxy-3,5,9-undecatriene of lycopene. An existing synthetic method have some disadvantages that it is very difficult to gain the raw material dialkyl 4-methyl-5,5-diakoxy-1-pentene-1-phosphonate (10) because no effective synthetic method can be adopted, and furthermore the obtained target compound is composed of several cis/trans isomers. This invention relates to a process comprising a condensation step wherein a starting C10-phosphonate is changed to its carbanion completely at a temperature of &#x2212;40&#x2dc;30 under an atmosphere of a non-reactive gas in an organic solvent catalyzed by base, and then C4-dialkyl is added to undergo Wittig-Horner condensation. This invention affords all trans C14-acetal and this method is characterized with the advantages of simple procedure, easy access to raw material and low cost, which makes it has the value of industrial application.
