Abstract: The present invention provides systems and methods for a content-addressable peer-to-peer storage network. The content-addressable peer-to-peer storage network includes a plurality of nodes. A node generates a new data block, which is witnessed by peer nodes to increase the integrity of the data. Each peer node responds to the node's signature request with an encoded digital signature of the data using a private key. The node appends the signature from each witness node to the data block and then generates a cryptographic hash of the entire data block, which is used as the identity of the block.

Abstract: A method for collective communications includes invoking a collective operation over a group of computing processes in which the processes concurrently transmit and receive data to and from other processes in the group via a communication medium. Messages are composed for transmission by source processes including metadata indicating how the data to be transmitted by the source processes in the collective operation are to be handled by destination processes that are to receive the data and also including in at least some of the messages the data to be transmitted by one or more of the source processes to one or more of the destination processes. The composed messages are transmitted concurrently from the source processes to the destination processes in the group over the communication medium. The data are processed by the destination processes in response to the metadata included in the messages received by the destination processes.

Abstract: Method, apparatus and system may control chronological sequencing of data items received from a plurality of client computing devices, according to times of completion of transmission respectively from the client computing devices and distributing the data items according to the chronological sequencing to one or more destination computing devices with minimal latency. In an exemplary implementation, trade orders from participant computing devices may be distributed by an electronic trading platform with minimal latency to exchange gateways, based on time of transmission of the trade orders to the platform instead of time of receipt of the trade orders by the platform, thereby avoiding unfairness to those participants whose computing devices are located at greater distances from the platform than other computing devices respectively of other participants.

Abstract: A bearing and/or seal assembly where pressurized gas (e.g., air) may be arranged to produce a contact-free bearing and/or seal is provided. The assembly includes a permeable body (12) including structural features (13) selectively engineered to convey a pressurized gas (Ps) from an inlet side (20) side of the permeable body to an outlet side (22) of the permeable body to form an annular film of the pressurized gas relative to the rotatable shaft. Disclosed embodiments may be produced by way of three-dimensional (3D) Printing/Additive Manufacturing (AM) technologies with practically no manufacturing variability; and may also cost-effectively and reliably benefit from the relatively complex geometries and the features and/or conduits that may be involved to, for example, form the desired distribution pattern or impart a desired directionality to the pressurized gas conveyed through the permeable body of the bearing and/or seal assembly.

Abstract: In a cell handover method and apparatus, first network device of a first cell obtains user information of a terminal device, and then the first network device may determine handover information based on the user information and running information of the first network device, so that after the first network device sends an RRC message including the handover information to the terminal device, the terminal device may perform N consecutive cell handovers based on the handover information. In the N cell handovers, the first network device only needs to obtain the user information once, to configure handover conditions for the N subsequent handovers in advance at a time. This simplifies a network signaling procedure, reduces network overheads, and reduces handover response time. The embodiments of this disclosure are applicable to a network handover in a satellite scenario.

Abstract: A method, apparatus and computer program product are provided to accelerate the estimation of a radio model of a beamforming access point within a radio environment, such as a beamforming access point that has been newly added to or relocated.

Abstract: Supporting multi-signal source communications in a distributed communications system (DCS) is disclosed. The DCS includes a routing circuit configured to route downlink and uplink communications signals between multiple signal sources and a number of remote units. In examples disclosed herein, the routing circuit and each of the remote units are functionally divided based on an open radio access network (O-RAN) Split 7.2 configuration. To support downlink communications from multiple signal sources, the routing circuit generates a downlink frequency-domain communications signal, which includes one or more selected logical channels associated with one or more of the multiple signal sources, for each of the remote units in the DCS. Accordingly, each remote unit converts the downlink frequency-domain communications signal into a downlink time-domain communications signal for transmission in a downlink radio frequency (RF) communications signal.
