Abstract: There is provided a method for conducting a lecture. The method including transmitting to a plurality of learner devices signals for providing a graphical user interface that presents one or more requests to the leaners to provide structured feedback at a corresponding plurality of first content locations predefined to be interspersed among a plurality of ordered content segments and one or more requests to the learners to provide unstructured feedback, receiving the structured and unstructured feedback from at least one of the learners, upon analyzing the structured and unstructured feedback, estimating engagement metrics each measuring a degree of engagement of the learners at a corresponding time points during the lecture, and transmitting to a lecturer device, data for generating a visual representation of the engagement metrics, including a graph of the degree of engagement over the plurality of time points and visually mapped to the content segments.

Abstract: Introduced here is a computer program that is representative of a software-implemented collaboration platform that is designed to facilitate conversations in virtual environments, document those conversations, and analyze those conversations, all in real time. The collaboration platform can include or integrate tools for turning ideas—expressed through voice—into templatized, metadata-rich data structures called “knowledge objects.” Discourse throughout a conversation can be converted into a transcription (or simply “transcript”), parsed to identify topical shifts, and then segmented based on the topical shifts. Separately documenting each topic in the form of its own “knowledge object” allows the collaboration platform to not only better catalogue what was discussed in a single ideation session, but also monitor discussion of the same topic over multiple ideation sessions.

Abstract: In various examples, systems for performing cloud-based updating of operating systems (e.g., root file systems) using system partitioning. For instance, a system(s) may initiate updates of the operating systems of machines, where the machines use system partitioning for the updating. More specifically, the system(s) may cause a machine to update the operating system using a standby system partition while the machine is currently running on another, active system partition. In some circumstances, the system(s) may perform these processes in order to update a cluster of machines, such as during a specific time period or at a certain frequency. By using such processes, the cluster of machines may still operate during the updating of the machines and/or even if the update fails on one or more of the machines.

Abstract: A portable tray is provided for use in a motor vehicle. The portable tray includes a base adapted to be supported on a vehicle seat and a pair of spaced apart legs depending therefrom. A front end is positionable toward a front portion of the seat, and a rear end is positionable toward a rear portion of the seat. An upper planar surface of the base provides a level support surface for articles being used by an occupant of the motor vehicle. At least one cavity into which articles can be placed is provided. A recess is provided through the side wall and is in communication with the cavity, and allows for an object to pass therethrough and into the cavity. An opening provided is the base and a strap having a seat anchor attached thereto extends through the opening. The strap has a thickened portion which is positioned on one side of the rear wall to secure the strap to the base.

Abstract: In examples, a parallel processing unit (PPU) operates within a trusted execution environment (TEE) implemented using a central processing unit (CPU). A virtual machine (VM) executing within the TEE is provided access to the PPU by a hypervisor. However, data of an application executed by the VM is inaccessible to the hypervisor and other untrusted entities outside of the TEE. To protect the data in transit, the VM and the PPU may encrypt or decrypt the data for secure communication between the devices. To protect the data within the PPU, a protected memory region may be created in PPU memory where compute engines of the PPU are prevented from writing outside of the protected memory region. A write protect memory region is generated where access to the PPU memory is blocked from other computing devices and/or device instances.

Abstract: In examples, trusted execution environments (TEE) are provided for an instance of a parallel processing unit (PPU) as PPU TEEs. Different instances of a PPU correspond to different PPU TEEs, and provide accelerated confidential computing to a corresponding TEE. The processors of each PPU instance have separate and isolated paths through the memory system of the PPU which are assigned uniquely to an individual PPU instance. Data in device memory of the PPU may be isolated and access controlled amongst the PPU instances using one or more hardware firewalls. A GPU hypervisor assigns hardware resources to runtimes and performs access control and context switching for the runtimes. A PPU instance uses a cryptographic key to protect data for secure communication. Compute engines of the PPU instance are prevented from writing outside of a protected memory region. Access to a write protected region in PPU memory is blocked from other computing devices and/or device instances.

Abstract: Bio-Inks and methods of using compositions comprising the bio-Inks are disclosed. 3-D tissue repair and regeneration through precise and specific formation of biodegradable tissue scaffolds in a tissue site using the bio-inks are also provided. Specific methylacrylated gelatin hydrogels (MAC) and methacrylated chitosan (MACh) preparations formulated with sucrose, a silicate-containing component (such as laponite), and/or a cross-linking agent (such as a photo-initiator or chemical initiator), as well as powdered preparations of these, are also disclosed. Kits containing these preparations are provided for point-of-care tissue repair in vivo. Superior, more complete (up to 99.85% tissue regeneration within 4 weeks applied in situ), and rapid in situ tissue repair and bone formation are also demonstrated.

Abstract: A memory manager of a processor identifies a block of data for eviction from a first memory module to a second memory module. In response, the processor copies only those portions of the data block that have been identified as modified portions to the second memory module. The amount of data to be copied is thereby reduced, improving memory management efficiency and reducing processor power consumption.
