A method for detection of misinformation without the need to analyze any articles (HINTS) includes forming a mixed graph containing at least two different node types, such as users and articles, with edges between users and articles, and with user weights for user nodes and article weights for article nodes. Seed nodes are planted for at least one user node and at least one article node. User weights and article weights are manually assigned to the seed nodes, then neighborhoods are defined for the seed nodes. A HITS-like algorithm is then run for a predetermined number of rounds updating both people and articles, while keeping the weights of the seed nodes constant to converge the graph for the weights of articles and users. Finally, a set of highest weights for users and/or articles is outputted and possible remedial action can be taken.

A distributed data storage system breaks data into n slices and k checksums using at least one matrix-based erasure code based on matrices with invertible submatrices, stores the slices and checksums on a plurality of storage elements, retrieves the slices from the storage elements, and, when slices have been lost or corrupted, retrieves the checksums from the storage elements and restores the data using the at least one matrix-based erasure code and the checksums. In a method for ensuring restoration and integrity of data in computer-related applications, data is broken into n pieces, k checksums are calculated using at least one matrix-based erasure code based on matrices with invertible submatrices, and the n data pieces and k checksums are stored on n+k storage elements or transmitted over a network. If, upon retrieving the n pieces from the storage elements or network, pieces have been lost or corrupted, the checksums are retrieved and the data is restored using the matrix-based erasure code and the checksums.

Methods and an apparatus for implementing a read cycle for identifying RFID tags among a plurality of RFID tags is disclosed. The read cycle comprises of selecting a group of items for reading and receiving identifiers from one or more items of the group, determining an aggregate data of the received identifiers, and comparing the aggregate data of the received identifiers with the aggregate data for the group from a previous read cycle. Further, where the aggregate data compared is equal, the read cycle is terminated, or where the aggregate data compared is not equal, the read cycle is repeated by forming at least one new group or by dividing the group into at least two subgroups and running the read cycle for each subgroup. The read cycle is performed in a time proportional to the number of tags that have changed and logarithmic in the total number of tags.

A distributed heterogeneous or homogeneous file storage system divides logical responsibility for data from actual control of the data by using separate file and storage managers. Each file manager provides access to stored files and stores metadata associated with each of the files for which it is responsible. A file manager control component allocates responsibilities among file managers, assigns management responsibilities for individual files, and maintains a record of which files are assigned to each manager. Each storage manager is responsible for managing storage of files on data storage devices and maintains a record of the location of each stored file. A storage manager control component allocates responsibilities among storage managers, assigns responsibilities for individual files, and maintains a record of which files and storage devices are assigned to each manager. A client provides user access, initiates actions within the system, and implements a redundant data recovery and reconstruction scheme.

The invention captures harvestable mechanical energy, e.g., in the form of wind or moving water, and uses it for electrical generation or other work. In various embodiments a turbine is used to pressurize a fluid, and the pressurized fluid is then optionally stored and then used to drive an electric generator. Because the pressurized fluid can be stored in a pressurized state indefinitely, the invention provides a straightforward way to accumulate the mechanical energy until it is needed. Additionally, the invention allows portions of the system, e.g., a pressure vessel or generator, to be located away from the turbine, reducing the costs of deploying and maintaining the system.

An improved system and method is provided for using sampling for scheduling advertisements in an online auction with budget and time constraints. A multi-armed bandit engine may be provided for sampling new advertisements by allocating advertisements for web page placements of equal quality and optimizing payments to maximize the welfare of the advertisers while remaining within advertiser's budget and time constraints. Advertisers may report their private information including arrival time, departure time, value per click, and budget. And the multi-armed bandit mechanism may approximate the maximal welfare that may be achieved under budget and time constraints by bounding the possible gain from any possible lie an advertiser might submit in reporting private information. Advertisers departing from the online auction may be charged using a payment method that may provide truthful guarantees on budget, arrivals, departures, and valuations for a budget-constrained online auction.

There is disclosed a method of operating a communications network having a plurality of selfish users. Each selfish user may send messages to a destination node with the messages being forwarded through intermediate nodes of a mesh network. Each selfish user may accumulate a debt equal to the power saved by having messages forwarded through other nodes in the mesh network less the power consumed forwarding messages for other nodes in the mesh network. Each selfish user having greater than zero accumulated debt may be required to forward messages for other nodes.
