Abstract: Methods, systems, and computer readable media for utilizing visuomotor error augmentation for balance rehabilitation are provided. An exemplary method includes displaying a dynamic virtual environment defined by an optical flow, obtaining position data of an anatomical portion of a subject that is virtually traversing the dynamic virtual environment, and using the position data to determine a mediolateral displacement measurement of the subject. The method further includes utilizing the mediolateral displacement measurement to define feedback control loop data, establishing an augmented visual error that dynamically adjusts the dynamic virtual environment, wherein the augmented visual error is based on the feedback control loop data and a predefined visual gain factor, and adjusting the optical flow of the dynamic virtual environment by using the augmented visual error.

Abstract: An edge device for monitoring safety of a highway work zone is disclosed. The edge device includes at least one camera, one or more processors, and memory. The at least one camera is configured to capture images in sequence. The memory stores computer-executable instructions that, when executed, cause the one or more processors to: perform vehicle detection over an input of a data stream of the images, from the at least one camera, utilizing just-in-time processing; determine a level of safety by tracking vehicles detected and performing a time sequence analysis of the vehicles; and send a signal to one or more assisted reality devices indicating the level of safety thereto.

Abstract: This specification describes systems and methods for using Zero Echo Time (ZTE) magnetic resonance imaging (MRI) sequences for applications to functional MRI (fMRI). In some examples, a system for functional magnetic resonance imaging includes a magnetic resonance imaging (MRI) scanner and a control console implemented on at least one processor. The control console is configured for executing, using the MRI scanner, a zero echo time (ZTE) pulse sequence; acquiring, using the MRI scanner, magnetic resonance data in response to the ZTE pulse sequence; and constructing at least one MRI image using the magnetic resonance data and measuring tissue oxygenation (PtO2)-related T1 changes as a proxy of neural activity changes of a subject using the at least one MRI image.

Abstract: Compositions and methods of transplanting cells by grafting strategies into solid organs (especially internal organs) are provided. These methods and compositions can be used to repair diseased organs or to establish models of disease states in experimental hosts. The method involves attachment onto the surface of a tissue or organ, a patch graft, a “bandaid-like” covering, containing epithelial cells with supporting early lineage stage mesenchymal cells. The cells are incorporated into soft gel-forming biomaterials prepared under serum-free, defined conditions comprised of nutrients, lipids, vitamins, and regulatory signals that collectively support stemness of the donor cells. The graft is covered with a biodegradable, biocompatible, bioresorbable backing used to affix the graft to the target site. The cells in the graft migrate into and throughout the tissue such that within a couple of weeks they are uniformly dispersed within the recipient (host) tissue.

Abstract: An apparatus for collecting or culturing cells or cell colonies includes: a common substrate formed from a flexible resilient polymeric material and having a plurality of wells formed therein; and a plurality of rigid cell carriers releasably connected to said common substrate, with said carriers arranged in the form of an array, and with each of the carriers resiliently received in one of the wells. A method of collecting or culturing cells or cell colonies with such an apparatus is carried out by depositing a liquid media carrying cells on the apparatus so that said cells settle on or adhere to said the carriers; and then (c) releasing at least one selected carrier having said cells thereon by gradual application of release energy to each carrier from the cavity in which it is received (e.g., by pushing with a probe).
