Abstract: In some embodiments provided herein is a method of preparing cargo-loaded platelets, comprising: treating platelets with a cargo and with a loading buffer comprising a salt, a base, a loading agent, and optionally ethanol, to form the cargo-loaded platelets.

Abstract: A projector sequentially generates light pulses to form a sparse grid array. The light pulses reflect off objects in an environment and are reflected towards a sensor array. The sensor array sequentially senses the reflected light pulses across pixels of the sensor array. A depth sensing system calculates depth information of objects in the environment based on the sequential nature of the pulse generation and the pulse sensing. The depth sensing system calculates depth information based on both the positional and temporal information of generated light pulses, and the positional and temporal information of sensed light pulses. The depth sensing system may generate a representation of the environment based on the depth information.

Abstract: Various embodiments of a fall-detection system for detecting personal fall while preserving the privacy of a detected person are disclosed. This disclosed fall-detection system can begin by receiving a sequence of video images comprising a person being monitored. The disclosed fall-detection system then processes each video image in the sequence of video images by: detecting the person in the video image; and extracting a skeletal figure of the detected person by identifying a set of human keypoints from the detected person. Next, the disclosed fall-detection system processes the sequence of skeletal figures corresponding to the sequence of video images by labeling each skeletal figure in the sequence of skeletal figures with an action among a set of predetermined actions. The disclosed fall-detection system subsequently generates a fall/non-fall decision for the detected person based on the set of action labels corresponding to the sequence of video images.

Abstract: A magnesium zinc oxide (MZO) nanostructure modified quartz crystal microbalance (MZOnano-QCM) takes advantage of the unique sensing ability and biocompatibility of MZO-based nanostructures, and combines them with the dynamic impedance spectrum capability of the bulk acoustic wave (BAW) devices including QCM, to form a real-time, noninvasive and label-free cell monitoring biosensor, specifically detecting the susceptibility and resistance of bacterial and fungal strains and cancer cells to various antibiotic and antifungal drugs and anticancer drugs, respectively.
