  • Publication number: 20230401081
    Abstract: Isolating resources of a virtual machine (VM) guest from a host operating system. A computer system receives an acceptance request from a guest partition corresponding to an isolated VM. The acceptance request identifies a guest memory page that is mapped into a guest physical address space of the guest partition, and a memory page visibility class. The computer system determines whether a physical memory page that is mapped to the guest memory page meets the memory page visibility class. The computer system sets a page acceptance indication for the guest memory page from an unaccepted state to an accepted state based on the physical memory page meeting the memory page visibility class.

  • Patent number: 11809381
    Abstract: Disclosed are systems and methods of accessing content items stored at a content management system by a mobile device, when the mobile device is not communicatively coupled to the content management system. The content management system can receive an indication to mark a content item (e.g., folder and the content items associated with the folder) as available to a mobile device when the mobile device is offline. The content management system can mark the content item, and any content items associated with the content item, for offline access by the mobile device and determine a synchronization schedule for the content item(s). The content management system can then initially send to the mobile device, the marked content item(s) in accordance with the synchronization schedule. While offline, the mobile device can make changes to the marked content items. The changes can be synchronized between the mobile device and content management system when the mobile device is online.

  • Patent number: 11731078
    Abstract: A desulfurization gas process includes water vapor, CO2 and SOx (x=2 and/or 3). In a treatment unit, the gas contacts a cooled alkaline aqueous solution having a temperature lower than an initial gas temperature, water and a carbonate of an alkali metal, to cool the gas, condense some water vapor and absorb SOx in the carbonate-containing solution, produce an SOx-depleted gas and an acidic aqueous solution including sulfate and/or sulfite ions. The SOx-depleted gas and a portion of the acidic aqueous solution can then be withdrawn from the treatment unit. Carbonate of the alkali metal can be added to remaining acidic aqueous solution to obtain a made-up alkaline aqueous solution. This solution can be cooled and reused as the cooled alkaline aqueous solution. An SOx absorbent solution includes a bleed stream from a CO2-capture process, sodium or potassium carbonate, and an acidic aqueous solution obtained from desulfurization.

  • Patent number: 11676024
    Abstract: Artificial neural network systems involve the receipt by a computing device of input data that defines a pattern to be recognized (such as faces, handwriting, and voices). The computing device may then decompose the input data into a first subband and a second subband, wherein the first and second subbands include different characterizing features of the pattern in the input data. The first and second subbands may then be fed into first and second neural networks being trained to recognize the pattern. Reductions in power expenditure, memory usage, and time taken, for example, allow resource-limited computing devices to perform functions they otherwise could not.

  • Publication number: 20230120072
    Abstract: Provided herein are hybrid capture-based methods to extract single-stranded DNA or RNA directly from non-treated biospecimens. The methods allow for the detection and analysis of unexplored short single-stranded DNA (sssDNA, mean length 50 nt) and ultrashort single-stranded DNA (ussDNA, mean length 15 nt) of human origin present in the biospecimen. The methods allow the discovery of unexplored short single-stranded DNA (sssDNA) in isolated red blood cells, which were believed to be deprived of nucleic acids because of the lack of a nucleus in mature red blood cells. The DNA or RNA extracted using the disclosed methods can be used as disease prognostic biomarkers and treatment predictive biomarkers.
