The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1390-1403, September 2026.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Critical Research Spaces as Scholarship: an Ethnography Lab as an Apparatus for the Experimental, the Imaginary, and the Relational

American Anthropologist, Volume 128, Issue 3, Page 469-479, September 2026.
ABSTRACT The creation of critical research spaces, such as ethnography labs, studios, and other collaborative research environments, requires attention and attunement in anthropology to focus on the kinds of imaginative and generative spaces where creative ethnographic research can unfold as scholarship.

Ground Penetrating Radar

2007
Ground penetrating radar2 (GPR) is an electromagnetic pulse reflection method based on physical principles similar to those of reflection seismics. It is a geophysical technique for shallow investigations with high resolution which has undergone a rapid development during the last two decades (cf. e.g. GPR Conference Proceedings 1994 to 2006).

Fundamentals of Ground Penetrating Radar

Symposium on the Application of Geophysics to Engineering and Environmental Problems 1989, 1989
Ground penetrating radar (GPR) is a relatively new technique for investigating shallow geologic, engineering and hydrologic features. The principles and theory are based on the wave equation derived from Maxwell’s Equations for electromagnetic wave propagation, and the antenna designs have evolved from field testing.
