Abstract: Various systems and methods are provided for MAR in CT images. A corrupted CT image, of a region of interest (ROI) of a subject, including artifacts caused by a metal object in the subject may be acquired. A corrupted sinogram including a corrupted region of corrupted data caused by the metal object and an uncorrupted region of uncorrupted data may be generated. A mask sinogram that delineates the corrupted region of the corrupted data may be generated. A corrected sinogram including the uncorrupted region of the uncorrupted data and an inpainted region of inpainted data corresponding to the corrupted region may be generated using a denoising diffusion probabilistic model, the corrupted sinogram, and the mask sinogram. A corrected CT image, of the ROI of the subject, that includes reduced artifacts relative to the artifacts in the corrupted CT image may be generated based on the corrected sinogram.

Abstract: A topical cluster hierarchy (TCH) is constructed by recursive subclustering of document clusters until a termination condition is detected. The clusters have centroids of topic proximity with respect to at least one user-specified topic. Subclustering starts after thresholds of minimal cluster topic proximity or minimal cluster coherence are met, thus avoiding processing of low-utility clusters. Subclustering terminates when sufficient topic proximity, coherence, or cluster depth is reached. A tool utilizes the TCH to control topic-directed searching, topic-directed filtering, analyzing, summarizing, or categorizing, of documents.

Abstract: A weighted multicategory querying (WMQ) tool generates alternates of an initial query through spelling correction, grammar correction, natural language processing, ambiguous term resolution, term normalization, keyword reordering, synonyms, and similar terms. The WMQ tool generates additional queries in different weighted categories such as keyword combination, query programming language (QPL), metadata, or embedding space. Query result individual topic proximity scores are combined with category weights to calculate a combined topic proximity score, which is employed to rank the query result. Embedding space query weight is increased for queries classified as broad. QPL query weight or metadata query weight is increased for queries which contain part or all of a metadata field name. Language models are leveraged for query generation, topic proximity scoring, or both.

The first controller writes first data to a first address in the nonvolatile memory and instructs the power supply circuit to apply the destruction voltage to the nonvolatile memory. The first controller determines whether the first data can be correctly read from the first address in the nonvolatile memory and checks destruction of the nonvolatile memory based on the determination.

Abstract: A computer-implemented method for performing a document search action includes receiving a search request identifying a sample document. A plurality of terms occurring within the sample document is identified. Each term is scored based on a global term frequency of that term within a collection of documents. Each term is then weight based on proximity, within the sample document, of that term to at least one of the other terms of the first plurality of terms. A document search query is created to include a proximity-limiting clause restricting results to include documents that have a highest-weighted term of the first plurality of terms within a threshold distance of another term of the first plurality of terms. The document search query is performed, thereby resulting in identification of a first resulting document.

The adjacent stand columns are connected by an upper support and a lower support. Each stand column is composed of an upper column body and a lower column body that are arranged coaxially.

Abstract: Techniques have been developed to facilitate the capture of performances on handheld or other portable computing devices and, in some cases, the pitch-correction and mixing of such vocal performances with backing tracks for audible rendering on such devices. Captivating visual animations and/or facilities for listener comment and ranking are provided in association with an audible rendering of a performance, e.g., a vocal performance captured and pitch-corrected at another similarly configured mobile device and mixed with backing instrumentals and/or vocals. Geocoding of captured vocal performances and/or listener feedback may facilitate animations or display artifacts in ways that are suggestive of a performance or endorsement emanating from a particular geographic locale on a user manipulable globe. In this way, implementations of the described functionality can transform otherwise mundane mobile devices into social instruments that foster a unique sense of global connectivity and community.

Abstract: A CT apparatus in which the x-ray source is coupled to a source robotic arm and the detector is coupled to a detector robotic arm. A motion correction module utilizes a locally linear embedding motion correction algorithm to estimate the geometry-describing parameters associated with the positions of the source and detector and the angle of the detector. These estimates are used to reconstruct the image data and produce corrected images with fewer errors resulting from patient movement, misalignments, and coordination issues in the system.
