The State of Virtual Healthcare

In recent years, telehealth or telemedicine has become an integral component of health systems. During the COVID-19 pandemic, telehealth became the primary route of treatment for patients and doctors. The goals of telehealth are to make healthcare more accessible to patients who have limited mobility, time, or transportation options and those who live in rural or isolated communities. Telehealth aims to improve coordination and care between healthcare teams and their patients. While addressing accessibility, telehealth sets health systems on a path to meet their decarbonization and energy reduction goals. The document provides insights and best practices for telehealth, including carbon reduction, space utilization, equitable access, and technology.

Dynamic, resilient virtual sensing system and shadow controller for cyber-attack neutralization

An industrial asset may have monitoring nodes (e.g., sensor or actuator nodes) that generate current monitoring node values. An abnormality detection and localization computer may receive the series of current monitoring node values and output an indication of at least one abnormal monitoring node that is currently being attacked or experiencing a fault. An actor-critic platform may tune a dynamic, resilient state estimator for a sensor node and output tuning parameters for a controller that improve operation of the industrial asset during the current attack or fault. The actor-critic platform may include, for example, a dynamic, resilient state estimator, an actor model, and a critic model. According to some embodiments, a value function of the critic model is updated for each action of the actor model and each action of the actor model is evaluated by the critic model to update a policy of the actor-critic platform.
