Abstract: Methods, systems, and non-transitory computer-readable media are configured to perform operations comprising determining an image of an environment. A drivable area and boundary information associated with the environment are determined based on the image. At least one boundary for navigation of the environment is generated based on the drivable area and boundary information.

Abstract: Systems and methods for providing individualized meeting content to participants in online meetings. Participant preferences may be summarized and displayed for speakers to see and attempt to follow, thus increasing the likelihood that meetings will progress according to the preferences of their attendees. Participants may also have their individual meeting feeds tailored to their preferences, if those preferences can be met in real time, during the meeting. Participants may further receive individual recordings of the meetings afterward, for those preferences that cannot be met in real time. In this manner, meeting participants may experience personalized versions of meetings, tailored to their particular preferences. This may improve participant interest in, and engagement with, online meetings.

Abstract: Machine learning is used to train a network to estimate a three-dimensional (3D) body surface and body regions of a patient from surface images of the patient. The estimated 3D body surface of the patient is used to determine an isocenter of the patient. The estimated body regions are used to generate heatmaps representing visible body region boundaries and unseen body region boundaries of the patient. The estimation of 3D body surfaces, the determined patient isocenter, and the estimated body region boundaries may assist in planning a medical scan, including automatic patient positioning.

Abstract: An integrated GHz ultrasonic neuro-cognitive system including a chip-cyborg having a network of biological neurons that forms a biological information processor, which can be controlled by electronics, optics, and GHz ultrasonic beams. In one example, the chip-scale microsystem includes a CMOS chip with RF CMOS and piezoelectric thin film transducers that can generate GHz ultrasonic waves, which can be phased to form narrow beams, achieving significant ultrasonic intensity to affect neurons. With a sufficient number of ultrasonic pixels, the focal point of the beam can be narrow enough to focus effect specific section of a neuron to enhance or decrease synaptic weights owing to ultrasonic radiation forces and acoustic streaming.

Abstract: A method for image processing performed by a computing device includes: (a) receiving one or more images and preprocessing the one or more images by extracting one or more features from the one or more images; (b) estimating image homographies (and/or fundamental matrices) based on the one or more features extracted from the one or more images; (c) determining particle trajectories based on composition of the image homographies (and/or fundamental matrices), wherein a particle trajectory comprises image pixel points identified in a subset of the one or more images; and (d) determining a joint estimation of camera pose, camera parameters, and a dense depth map using the particle trajectories.

Abstract: Provided are compositions and methods that relate ex vivo organoids that contain B cells and stromal cells in a three dimensional material includes a hydrogel. The hydrogel can be formed without exposure to ultraviolet light from an electronic ultraviolet light source. The hydrogel contains silicate nanoparticles (SiNPs) that are ionically bonded to a polyampholytic gelatin. The three dimensional material can be held at a temperature of at least 37 degrees Celsius and does not liquefy. The organoids exhibit mechanical properties that are similar to certain lymphoid tissues, and can include a germinal center. Methods of making the organoids are included, as are high throughput screening approaches that use the organoids for screening a variety of test agents. The organoids can synthesize a variety of compounds that can be recovered from the organoids or the organoid culture medium.
