An unsupervised machine learning approach to iron meteorite classification
Meteoritics &Planetary Science, EarlyView.Abstract Iron meteorites are usually classified manually using bivariate elemental plots. This study extends iron meteorite classification into multi‐element space. We present a computational method for the classification of iron meteorites by applying unsupervised machine learning using density‐based cluster analysis.

Sedimentology, EarlyView.ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

Seasonal and annual variations of sugarcane within-field variability, as observed in spot time series [PDF]
, 2007 At the field scale, crop spatial variability is related to multiple factors that are time-dependant. In this paper, we analyzed the within-field variability of a sugarcane crop at two different time-scales, season and year, and try to relate this ...

Suspicion: The politics of knowledge production when fieldwork and writing are uneasy
The Australian Journal of Anthropology, EarlyView.Abstract How might fieldwork anxieties serve as a productive site to revisit the theoretical presumptions that guide research practices? This article explores moments of suspicion and scepticism during fieldwork to reflect on the tensions of fixing anthropological lines of inquiry and conceptual lineages.
