A newly revised estimation of bulk densities and examination of the shape of individual Ryugu grains

Earth, Planets and Space, 2023
The bulk density of grains from a celestial body is a fundamental property related to its composition and structure, contributing to the understanding of its evolutionary history. In this study, we provide the bulk density of 637 grains returned from the

Space exploration in neglect [PDF]

Brain, 1998
The present study investigated the gaze as well as the head and the eye-in-head movements of neglect patients while they were exploring their surroundings. A random configuration of letters was presented on the inner surface of a sphere that surrounded the subject, requiring free exploratory eye and head movements. The subjects were requested to search
