Incremental Shifts, Strategic Orbits: The Evolution of EU Space Policy Through Gradual Security Linkages

open access: yesGlobal Policy, EarlyView.
ABSTRACT This article examines the evolution of European Union (EU) space policy through the lens of historical institutionalism, highlighting how security and defence considerations have been incrementally integrated into a domain originally framed as civilian and scientific.

Multi-Objective Optimization Method for Comprehensive Modification of High-Contact-Ratio Asymmetrical Planetary Gear Based on Hybrid Surrogate Model

open access: yesMachines
The contact performance of high-contact-ratio asymmetrical planetary gears is comprehensively evaluated using multiple indicators. The relationship between the indicators and modification parameters is difficult to accurately describe with a single type ...

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.

(Un)threading Rhythms: On Affect and Vibe in a Rave

open access: yesAnthropology of Consciousness, EarlyView.
ABSTRACT In Toronto, raves arise across large nightclubs, DIY venues and outdoors, despite changing regulations that have further arranged and narrowed their possibility in the past 4 years. Following a rave in Toronto, this work explores ways that potentialities and affects emerge in a single night, through my entry of taking part in dancing and ...

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

open access: yesBoreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

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

open access: yesConservation 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.

Understanding the Range and Impact of Visitor Experiences at Science Museums

open access: yesCurator: The Museum Journal, EarlyView.
ABSTRACT While the core mission of science museums is to provide engaging learning experiences that promote scientific literacy among the visiting public, attention has recently been focused on the wide range of visitor experiences that surround and support visitor learning.

Efficiency analysis of planetary gears [PDF]

open access: yes, 2018
By kinematic combinations of toothed pairs with external and internal contacts, we can obtain planetary gears with a considerably improved performance than the corresponding ones with fixed axes, as well as planetary gears with notably poor performance regarding the efficiency.
