Time-varying Reliability Analysis of Planetary Gear Reducers Based on Fatigue Failure

Jixie chuandong
With technological innovation and social development, the reliability of planetary gear reducers is required to be higher and higher. However, the reliability of planetary gear reducers changes due to fatigue factors in its operation.

Countdown to extinction: Role of invasive wild boars in the population dynamics of the Yelkouan shearwater (Puffinus yelkouan) on Port‐Cros Island

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Wild boars that have recently arrived in Port‐Cros National Park are reducing the reproductive success of Yelkouan shearwaters by destroying nests and predating on eggs and chicks. In the absence of measures to control the wild boar population, this would likely accelerate the decline of the Yelkouan shearwater population.

Terrestrial Ecosystem Detection Based on Deep Learning Framework and Satellite Image Geographical Information

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
The proposed deep learning framework integrates ResNet‐50 and LSTM models to detect and classify terrestrial ecosystems from satellite imagery. The workflow begins with image preprocessing using bilateral, guided, and median filters to enhance image quality and preserve edges.

Out There No One Has a Right to Die

Bioethics, Volume 40, Issue 6, Page 565-572, July 2026.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have
