Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

Journal of Field Robotics, EarlyView.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Variable species establishment in response to microhabitat indicates different likelihoods of climate‐driven range shifts

Ecography, EarlyView.
Climate change is causing geographic range shifts globally, and understanding the factors that influence species' range expansions is crucial for predicting future biodiversity changes. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically ...

‘Unbecoming’ a Professional: The Role of Memory during Field Transitions in Japan and the USA

Journal of Management Studies, EarlyView.
Abstract Existing scholarship documents how, in becoming a professional, such as a partner in a professional services firm (PSF), one's habitus comes into alignment with field expectations. Less understood, however, is what happens to habitus and, relatedly, to professionals' accumulated cultural, social, and economic capitals, as individuals ‘unbecome’
