Building the Prototype Open Knowledge Network (Proto-OKN)

This program supports the creation of a prototype Open Knowledge Network — an interconnected network of knowledge graphs supporting a very broad range of application domains. Open access to shared information is essential for the development and evolution of artificial intelligence (AI) and AI-powered solutions needed to address the complex challenges facing the nation and the world.

Computational Models of Cerebrospinal Fluid and Vascular Flow Dynamics (Human Spaceflight)

Some crewmembers on long-duration missions to the International Space Station (ISS) have experienced ophthalmic anatomical changes and visual performance decrements with varying degrees. In these cases, data suggest that intracranial pressure is simultaneously increased. NASA medical operations and research personnel have hypothesized that the microgravity induced cephalad fluid shift may be partially responsible for the observed ophthalmic changes through biomechanical means.
