Fungal foraging behaviour and hyphal space exploration in micro-structured Soil Chips
The ISME Journal, 2021 How do fungi navigate through the complex microscopic maze-like structures found in the soil? Fungal behaviour, especially at the hyphal scale, is largely unknown and challenging to study in natural habitats such as the opaque soil matrix.

An MCMC approach to extracting the global 21‐cm signal during the cosmic dawn from sky‐averaged radio observations [PDF]
, 2011 Efforts are being made to observe the 21-cm signal from the ‘cosmic dawn’ using sky-averaged observations with individual radio dipoles. In this paper, we develop a model of the observations accounting for the 21-cm signal, foregrounds and several major ...

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

Use of Photobioreactors in Regenerative Life Support Systems for Human Space Exploration
Frontiers in Microbiology, 2021 There are still many challenges to overcome for human space exploration beyond low Earth orbit (LEO) (e.g., to the Moon) and for long-term missions (e.g., to Mars).

Multi-Robot Space Exploration: An Augmented Arithmetic Approach
IEEE Access, 2021 Space exploration refers to constructing a map with the aid of sensor data. This exploration is achieved utilizing a group of robots in an obstacle cluttered environment and distributing tasks amongst these robot(s). The robotic configuration is equipped

A Design Space Exploration of Worlds in Miniature
International Conference on Human Factors in Computing Systems, 2021 Worlds-in-Miniature (WiMs) are interactive worlds within a world and combine the advantages of an input space, a cartographic map, and an overview+detail interface. They have been used across the extended virtuality spectrum for a variety of applications.

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
