Abstract: An electronic device and method for using neural language models for long-term action anticipation from videos is provided. The electronic device receives a video that includes one or more objects performing a physical task and generates, based on the video, a first set of tags that corresponds to a first sequence of actions associated with the physical task. The electronic device generates a first prompt for a neural language model based on the first set of tags and predicts, by application of the neural language model on the first prompt, a second set of tags that corresponds to a second sequence of actions associated with the physical task. The second sequence of actions succeeds the first sequence of actions. The electronic device controls a display device to display first prediction information based on the second set of tags.

Abstract: An electronic device and method for object-centric video representation for action prediction is provided. The electronic device extracts a first sequence of video segments from video content associated with a domain and detects a set of objects in the first sequence of video segments. The electronic device generates a set of embeddings based on the first sequence of video segments and the set of objects. The electronic device applies a PTE model on the set of embeddings. The electronic device predicts, based on the application, a set of object-action pairs associated with a second sequence of video segments of the video content. Each object-action pair includes an action to be executed using an object of the set of objects in a video segment of the second sequence of video segments. The second sequence of video segments succeeds the first sequence of video segments in a timeline of the video content.

Abstract: A method includes receiving data, flagging outliers in the received data, each of the outliers representing extreme data values in the received data that stand out greatly from an overall pattern of data values at a given scale in the received data, storing the flagged outliers in an outlier file, removing the flagged outliers from the received data, curating the flagged data points with respect to various neighborhood kernel sizes, and further curating data points with small perturbations using contextual custom regression techniques as a second order refinement process.

Abstract: A method includes providing an ensemble of distributed sensors, delivering radio frequency (RF) power to each sensor by inductive near-field coupling by a magnetic field projected by an epidermal transmit (Tx) coil, in each individual sensor, detecting a sparse binary event in its immediate environment, reporting the detected sparse binary event to an external RF receiver hub asynchronously and with low latency, and minimizing error rates due to statistical data packet collisions in asynchronous telemetry by digitally encoding each sensor according to a particular address scheme where each address is one function from an infinite set of mathematically orthogonal functions, enabling a simultaneous detection from up to ten thousand points without interference at a common receiver.

Abstract: The invention provides enhancer RNAs (eRNAs) that are expressed specifically in glioma stem cells and whose expression correlates with decreased survival of patients with glioblastomas. The eRNAs are selected, for example, from eTMEM88b, eRTP5, or eNINJ1. The invention also provides an RNA therapy that targets glioma stem cell eRNAs using synthetic oligonucleotides that knock out the eRNA expression. The invention further provides viral vectors that deliver shRNA that inhibit the expression of the eRNA.

Abstract: A patient communication system comprises a hand-held data input subsystem and a display subsystem. The data input subsystem may be configured to sense, and wirelessly convey, information associated with 3-D movement of the data input subsystem, and actuation of a signaling element within the data input subsystem. The display subsystem may receive the information and to present a visual representation of the information in a graphical user interface (GUI). The display subsystem may adaptively interpret the information with respect to range of motion sensitivity and orientation of the data input subsystem, and movement of the data input subsystem with respect to its prior state. The system may map the conveyed information to the GUI, generate and display images on the GUI with which a patient may interact by manipulating the data input subsystem, and capture one or more selections executed by the patient through actuation of the signaling element.

Abstract: A thermal accelerant is delivered to a tissue site and localized to modulate the shape, extent or other characteristic of RF or microwave-induced hyperthermic tissue ablation. The accelerant may be provided via an image-guided hand piece or via a lumen added to a microwave antenna, and promotes faster heating, more complete ablation and/or a more extensive treatment region to reduce recurrence of treated cancers, overcoming natural limitations, variations in tissue response and drop-off or thermal loss away from the antenna. The accelerant is delivered as a viscous but heat sensitive fluid, and is fixed in place to provide regions of preferential absorption or heating. Shorter exposure times to heat the far field may allow survival of vulnerable tissue such as vessels, and multiple antennae may be used for effective treatment of irregular or large tumors.

Abstract: The present disclosure generally relates to mass spectrometers, including but not limited to mass spectrometers able to emit ions at determinable times. In some aspects, the time between when ions leave an ion source and the time the ions reach a detector may be determined at a relatively high time resolutions, which may be useful for certain applications such as sequencing of biopolymers. In addition, in some cases, a relatively high number of ions leaving an ion source may be determined at a detector, e.g., at least 50% or more of the ions that are produced. Other aspects are generally directed to systems and methods for using such mass spectrometers, techniques involving such mass spectrometers, or the like.
