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.

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.

The application of an activation threshold voltage to the accelerator results in a surge in system performance parameters.

Abstract: A proactive fault-tolerant scheme which improves performance and energy efficiency for NoCs. The fault-tolerant scheme allows routers to switch among several different fault-tolerant operations. Each operation mode has different trade-offs among fault-tolerant capability, retransmission traffic, latency, and energy efficiency. Another example provides a proactive, dynamic control policy to balance and optimize the dynamic interactions and trade-offs. The example control policy uses example machine learning algorithm called reinforcement learning (RL). The example RL-based controller independently observes a set of NoC system parameters at runtime, and over time they evolve optimal per-router control policies. By automatically and optimally switching among the four fault-tolerant modes, the trained control policy results in minimizing system level network latency and maximizing energy efficiency while detecting and correcting errors.

Abstract: A cardiac patch for treatment of a mammalian heart including perfusable vessels embedded integratedly between two layers of anisotropically oriented myocardial fibers. The cardiac patch is made using a dual 3D bioprinting technique using stereolithography to form an anisotropic construct and extrusion printing to form perfusion vessels. A nutrient and oxygen containing media can be provided within the perfusion vessels for growth of cells in the cardiac patch. The technique permits larger patches to be made for the treatment of cardiac damage in both small and large mammalian hearts.
