A plug (2) comprising: a ring (10); and an insert (12) inserted within the ring, wherein the insert comprises a head, a body and an opening for passing a cable or a pipe through the head and the body, wherein the insert is made entirely of intumescent material.

A sensory toy for a baby comprises an arch for supporting one or more images, the arch comprising a first sheet and a second sheet, the first and second sheets having folds and being connected by slot joints to form a plurality of A-frames arranged in series along the arch. In use, the sensory toy may encourage the baby to tilt their head to look at the sensory toy, and may help the baby develop their neck muscles and head control, as well as providing a visual stimulus to the baby to aid neurological development. Another aspect provides a kit of parts for assembling the sensory toy.

Methods, devices, and data structures for processing large volumes of transactions in blockchain nodes. Solutions are provided for transaction clean-up following receipt of a block announcement from another node. In one example, transaction identifiers in a list matching the local candidate block are marked if they match transaction identifiers in the announced block and, once the block is validated, the block assembly service uses unmarked transaction identifiers to build the new candidate block. In other examples, a candidate database of transaction identifiers is built during the mining phase and TxIDs are marked with an array identifier or a node identifier as arrays are announced by other nodes on the network. This may speed clean-up once the block is announced and reduces memory footprint for carrying out the post-solution marking of TxIDs as being included in the solved block.

A computer-implemented method for generating an identity-based cryptographic key, the method comprising: obtaining a set of private key shares and a set of corresponding public key shares, wherein each private key share is generated based on the personal identifier, and wherein at least one of the set of private key shares is generated by a respective one of a set of key-generating parties; generating an identity-based private key based on each of the one or more private key shares; and generating a partial identity-based public key, wherein the partial identity-based public key is generated based on each of the set of corresponding public key shares; transmitting the partial identity-based public key to at least one of the set of key-generating parties for generating the identity-based public key; and/or generating the identity-based public key, wherein the identity-based public key comprises the personal identifier and the partial identity-based public key.

Systems and computer-implemented methods for freezing or unfreezing digital assets on a blockchain. A freeze administration service may send a signed freeze request to mining nodes, which maintain two blacklists of digital asset identifiers: a pending blacklist and a consensus blacklist. The digital asset identifiers may be transaction outpoints in some cases. If accepted by the mining node, the transaction outpoints in the freeze request are added to the pending blacklist, which causes rejection of any transactions using those outpoints, but does not cause rejection of any new blocks that include transactions using those outpoints. If a consensus threshold of acceptances is reached based on hash power, the request becomes an order and the outpoints are added to the consensus blacklist, which causes rejection of any transaction or block containing a transaction using those outpoints.

There is disclosed a transportable medical unit for the provision of radioligand therapy or molecular radiotherapy services, comprising: one or more treatment rooms, each treatment room having lead walls and a lead ceiling, wherein in a first state, the unit is lifted off the ground, and in a second state the unit is placed on the ground such that the floor of the unit is in contact with the ground.

Various strategies for training a machine learning model are provided. One method computes a gradient matrix of a training loss function and applies a whitening transformation. Gradient normalization and whitening are employed to update weight vectors solely based on current gradient information without the need for exponential moving averages. A second method determines a state matrix to derive a truncated basis matrix composed of selected principal eigenvectors and additional orthogonal vectors and calculates an updated weight by projecting the gradient onto this low-dimensional subspace.

A computer-implemented method includes storing threat intelligence documents and a graph data store. The graph data store includes entity nodes and a plurality of edges between the nodes extracted from the plurality of threat intelligence documents. Data is also stored linking the entity nodes and edges to the threat intelligence documents from which they were extracted. A generative machine learning model is employed to generate a summary text of threat intelligence for a first entity node, based on the first entity node, second entity nodes connected to the first entity node and the threat intelligence documents from which they were extracted. The summary text is inserted as a summary node into the graph comprising the generated summary text.

This disclosure enhances a resilient high-bandwidth state-transition computer by incorporating a novel decentralized platform. The decentralized platform introduces a hierarchical, multi-level architecture utilizing node-sets and validation clusters to achieve exceptional scalability, fault tolerance, and data integrity. Entities, comprising distinct data sets, are distributed across node-sets, each maintaining a blockchain to record state changes. Node-set-level Merkle trees provide efficient data verification within node-sets, while a global Merkle tree combines node-set states into a unified representation of the global state, verified through consensus among validation clusters. This multi-dimensional cryptographic linking, enhanced by inter-node-set activations, creates a robust and tamper-proof system capable of handling millions of entities and ensuring data consistency across a distributed network.

A cap configured for engagement with a coupling can comprise an annular ring extending circumferentially around an outer portion of the cap, the cap defining an inner end and an outer end disposed opposite from the inner end, the annular ring defining a sealing surface between the inner end and the outer end, the annular ring defining a raised lip at the inner end, the raised lip extending radially outward from the sealing surface; and a web, the web enclosing the annular ring.
