Dynamic Response of Planetary Bearings in a Double Planetary Gear Train with Forward and Reverse Carrier Rotations

Machines
Planetary bearings are critical components in double planetary gear trains. The influence of carrier rotation direction on bearing dynamic behavior remains insufficiently understood, which hinders accurate reliability assessment and optimal design.

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, EarlyView.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

Conservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

The hole in the doughnut: Formalizing and testing a key model of degrowth

Contemporary Economic Policy, EarlyView.
Abstract Degrowth scholars often claim that capitalism generates social and ecological imbalances, as captured by Kate Raworth's leading doughnut model. We formalize this model using social and environmental indices and measure imbalances using their coefficient of variation.

Global distribution of aquatic animal telemetry effort reveals geographic biases and opportunities for more inclusive tracking studies

Conservation Science and Practice, EarlyView.
Despite broad global distribution of aquatic telemetry studies, important biogeographic regions remain poorly investigated. The most important variables correlated with the distribution of telemetry studies were political stability, conservation funding, number of scientific documents, and English as a first language.
