Opening the Black Box of the Radiation Belt Machine Learning Model
Space Weather, 2023 Many Machine Learning (ML) systems, especially deep neural networks, are fundamentally regarded as black boxes since it is difficult to fully grasp how they function once they have been trained. Here, we tackle the issue of the interpretability of a high‐

Understanding the Mechanisms of Radiation Belt Dropouts Observed by Van Allen Probes [PDF]
Journal of Geophysical Research: Space Physics, 2017 AbstractTo achieve a better understanding of the dominant loss mechanisms for the rapid dropouts of radiation belt electrons, three distinct radiation belt dropout events observed by Van Allen Probes are comprehensively investigated. For each event, observations of the pitch angle distribution of electron fluxes and electromagnetic ion cyclotron (EMIC)

Feminist Anthropology, EarlyView.Abstract In this article, I blend authoethnography and ethnography to activate a Chicanx feminist theory of the flesh, which is grounded in the sensibilities of vulnerability and rasquachismo. Rasquachismo is a politicized Mexican American visceral modality of being in the world—in art, in politics, in everydayness—that is rooted in purposeful defiance

Space Weather, 2022 In this study, we present an empirical model of the equatorial electron pitch angle distributions (PADs) in the outer radiation belt based on the full data set collected by the Magnetic Electron Ion Spectrometer (MagEIS) instrument onboard the Van Allen ...

Frontiers in Astronomy and Space Sciences, 2022 Nonlinear processes are involved in both the growth of VLF chorus waves and the energization of radiation belt electrons trapped in the wave potential. Nonlinear theory has led to analytic formulae describing both these processes.

Love Affair With Thin Air: Mortality, Mastery, and the Consumerism of Mountaineering
Psychology &Marketing, EarlyView.ABSTRACT Mountaineering is arguably one of the most dangerous recreational challenges an individual may ever choose to undertake, yet millions of people annually venture above 8000 feet to challenge themselves in pursuit of personal goals, ideals, and support of individual values.

People and Nature, EarlyView.Abstract There is growing interest in using urban greening projects to support biodiversity. While there are many potential co‐benefits, the health outcomes resulting from biodiversity‐supporting activities have yet to be synthesized. We conducted a systematic review of health outcomes associated with seven biodiversity‐supporting elements, including ...

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao
PLANTS, PEOPLE, PLANET, EarlyView.Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...
