Abstract: Systems and methods are disclosed for improving on-chip security, while minimizes the latency and cost of security techniques to improve system-level performance and power simultaneously. The framework uses machine learning algorithms, such as an artificial neural network (ANN), for runtime attack detection with higher accuracy. Further, a learning-based attack mitigation method using deep reinforcement learning is disclosed, where the method may be used to isolate the malicious components and to optimize network latency and energy-efficiency.
Abstract: Systems and methods are disclosed for air flow optimization. In certain embodiments, the technology is a system comprising sensors, injectors, actuators, and a system processor. In order to optimize the air flow, the system processor directs the injectors to expel aerosol particles into an environment, such that the aerosol particles can be measured by the one or more sensors. Flow intensity map generation is then used to map the aerosol particles and air flow is changed to optimize aerosol particle concentration using the actuators.

Abstract: A cyber-physical system for conducting a telehealth session. In embodiments, the system includes a hardware control box that enables patients (e.g., elderly or cognitively-impaired patients) to easily participate in the telehealth session. In some embodiments, the system analyzes sensor data (e.g., thermal images, eye tracking data, etc.) and calculates state variables that form a mathematical representation (a “digital twin”) indicative of the physical, emotive, cognitive, or social state of the patient. In some of those embodiments, the system calculates Myasthenia Gravis core examination metrics by performing computer vision analysis on patient video data and/or audio analysis on patient audio data. In some embodiments, the system controls a pan-tile-zoom camera to zoom in on each region of interest that is relevant to the examination.

Abstract: A photonic Mach Zehnder Interferometer (MZI) has a first arm with a first photonic waveguide transmitting a first light having a first phase, a second arm with a second photonic waveguide transmitting a second light having a second phase, and a Transparent Conducting Oxide (TCO) based assembly. The TCO assembly is positioned about the first photonic waveguide of the first arm to modulate the first phase of the first light traveling in the first photonic waveguide.
Abstract: Due to the precautions put in place during the COVID-19 pandemic, utilization of telemedicine has increased quickly for patient care and clinical trials. Unfortunately, teleconsultation is closer to a video conference than a medical consultation with the current solutions setting the patient and doctor into a discussion that relies entirely on a two-dimensional view of each other. A telehealth platform is augmented by a digital twin of the patient that assists with diagnostic testing of ocular manifestations of myasthenia gravis. A hybrid algorithm combines deep learning with computer vision to give quantitative metrics of ptosis and ocular muscle fatigue leading to eyelid droop and diplopia. The system works both on a fixed image and video in real time allowing capture of the dynamic muscular weakness during the examination.

Abstract: Systems and methods for microscopic imaging include an inverted microscope directed at a sample on a coverglass, where the sample is comprised of one or more cells and one or more chromophores. A ridge separates the coverglass from a silicon dioxide layer, and a silicon mirror is situated on the silicon dioxide layer, opposite the ridge and coverglass, while a weight is situated against the silicon mirror, opposite the silicon dioxide layer. The inverted microscope uses a spatial light modulator to diffract light through a linear polarizer and a filter wheel comprised of one or more Fourier filters. A beam or beams of s-polarized light is directed to the silicon mirror to create axial light modulation with its reflection on the silicon mirror, producing image data that is captured at a light detector.
