Abstract: Embodiments may provide a cache for query results that can adapt the cache-space utilization to the popularity of the various topics represented in the query stream. For example, a method for query processing may perform receiving a plurality of queries for data and requesting data responsive to at least one query from a data cache comprising a temporal cache, wherein the temporal cache is configured to store data based on a topic associated with the data and is configured to retrieve data based on a topic, and wherein the data cache is configured to retrieve data responsive to at least one query from the computer system.

Abstract: Methods of inhibiting release of one or more cytokines, or inhibiting a cytokine storm, or preventing cytokine release syndrome or a cytokines storm, in a subject infected with severe acquired respiratory syndrome coronavirus 2. The method involves administering to the subject an effective amount of one or more NAD+ precursors, one or more inhibitors of stimulator of interferon genes (STING), one or more famesoid X receptor (FXR) agonists, or a combination thereof. In addition, treatment regimens involving the use of one or more NAD+ precursors, one or more STING inhibitors, one or more FXR agonists, or a combination thereof; and kits comprising pharmaceutical compositions of one or more NAD+ precursors, one or more inhibitors of stimulator of interferon genes, one or more farnesoid X receptor agonists, or combinations thereof.
Abstract: A method for training vibrotactile speech perception in the absence of auditory speech includes selecting a first word, generating a first control signal configured to cause at least one vibrotactile transducer to vibrate against a person's body with a first vibration pattern based on the first word, sampling a second word spoken by the person, generating a second control signal configured to cause at least one vibrotactile transducer to vibrate against the person's body with a second vibration pattern based on the sampled second word, and presenting a comparison between the first word and the second word to the person. An array of vibrotactile transducers can be in contact with the person's body.

Abstract: A specialized computing environment that includes hardware and data security features to enable competitive organizations to co-analyze proprietary data without revealing the underlying proprietary data to unauthorized users. Proprietary data are stored in volatile memory, which may be automatically erased according to pre-stored criteria. The analysis is performed automatically by a processing unit without human intervention. Analytical results are sanitized (e.g., using data masking) to prevent the analytical result from being tracible to any particular data source. Sanitized analytical results are output without outputting the underlying proprietary data (except to users authorized to validate analytical results). The computing environment is enclosed within a secure enclosure (e.g.

Abstract: Methods of generating a population of tumor cells, such as circulating tumor cells (CTCs) isolated from fluid from a subject. The methods involve collecting a fluid sample containing the tumor cells from the subject, and culturing the tumor cells in the fluid sample in a three-dimensional cell culture, wherein the three-dimensional cell culture comprises at least one inhibitor of Rho-kinase to generate the population of CTCs. If the fluid is whole blood or contains blood, the method may also involve subjecting the fluid sample to density gradient separation to separate the tumor cells from the fluid prior to culturing. In addition, methods of identifying a candidate treatment for a subject having a condition marked by the presence of tumor cells, methods of monitoring in a subject the persistence, regression, or progression of a disease or condition marked by the presence of tumor cells, and methods of generating a cell line of tumor cells.

Abstract: Embodiments of the present systems and methods may provide techniques for synthesizing speech in any voice in any language in any accent. For example, in an embodiment, a text-to-speech conversion system may comprise a text converter adapted to convert input text to at least one phoneme selected from a plurality of phonemes stored in memory, a machine-learning model storing voice patterns for a plurality of individuals and adapted to receive the at least one phoneme and an identity of a speaker and to generate acoustic features for each phoneme, and a decoder adapted to receive the generated acoustic features and to generate a speech signal simulating a voice of the identified speaker in a language.
Abstract: A method for treating against, or at least inhibiting or suppressing, the proliferation of an internal ribosome entry site-utilizing virus (IRES-utilizing virus) involves administering a compound, a tautomer, or a pharmaceutically acceptable salt thereof, in an amount effective for inhibiting replication of the IRES-utilizing virus in cells, wherein the compound is represented by the formula: wherein each R1 is independent of the other and represents a halogen atom selected from the group consisting of bromo, chloro, fluoro and iodo.

Abstract: A gait analysis system, which includes a neural network with a recurrent neural network layer and a fully connected layer, that receives sensor data indicative of an individual's gait and outputs an assessment regarding the individual's health. The neural network is trained using training data indicative of abnormal gaits and normal gaits. To analyze the training data and the sensor data, the recurrent neural network layer parses each piece of data into a series of windows and analyzes each window in series to generate a context vector characterizing each window and the previously analyzed windows. The fully connected layer, having been trained to differentiate between normal gaits and abnormal gaits based on context vectors characterizing the training data, is used to generate a final assessment characterizing the user gate as normal or abnormal using one or more of the context vectors characterizing the sensor data.
Abstract: A method effective in treating a viral infection involves administering a therapeutically effective amount of at least one compound capable of inhibiting expression of at least a portion of a virus genome containing an internal ribosomal entry site, or a pharmaceutically acceptable salt thereof. The compound has an azole moiety comprising a five member heterocyclic ring containing at least one nitrogen atom, a hydrophobic moiety bonded to the heterocyclic ring of the azole, and a donor/acceptor moiety bonded to the heterocyclic ring having at least one of hydrogen bond donor and a hydrogen bond acceptor.
