Buckling analysis of flexspline in harmonic gear reducers

Journal of Physics: Conference Series
Abstract Harmonic gear reducers are widely used in the field of precision machinery due to their advantages of high transmission accuracy, large reduction ratio, and compact structure. As the core transmission component, the flexspline’s stability directly determines the performance and service life of the reducer.

A Methodological Pathway for Supporting the Transition From Theory to Practice in Action‐Oriented Research for Transformative Change

Sustainable Development, EarlyView.
ABSTRACT Over recent decades, action‐oriented research has gained prominence in co‐producing actionable knowledge to drive transformative change toward sustainability. However, further methodological developments are needed to support the transition to the application phase of such knowledge.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

An effective identification method of gear fault

Gong-kuang zidonghua, 2014
In view of problem that feature information of gear fault often submerged by noise in signal, an identification method of gear fault based on harmonic wavelet package, sample entropy and grey correlation degree was proposed. Firstly, the method uses rank-

High‐Speed Rail and Spatial Equity: Unpacking the Sustainability Paradox of Land Use and Fiscal Pressure in County‐Level Cities

Sustainable Development, EarlyView.
ABSTRACT Infrastructure‐led development in rapidly urbanizing economies often generates accessibility gains that fail to translate into balanced urban outcomes, particularly when local fiscal institutions redirect those gains toward revenue‐generating land uses. Filling this gap, especially in fiscally constrained county‐level cities where land finance

Bridging Global Sustainability Objectives With Corporate Reporting Standards: Sustainable Development Goals Meet European Sustainability Reporting Standards

Sustainable Development, EarlyView.
ABSTRACT Given the complexity of the Sustainable Development Goals (SDGs), aligning corporate sustainability with them can be challenging. Drawing on systems thinking, this study examines how the European Sustainability Reporting Standards (ESRS) align with the SDGs and bridge macro‐level global goals with firm‐level metrics.

Navigating Classical and Nonclassical Realms of Nucleation and Crystallization

Small, EarlyView.
Classical nucleation and growth theories have long been foundational, yet recent nonclassical concepts have challenged and refined our understanding of solid‐state genesis. This paradigm shift introduced new, often ambiguous vocabulary. Here, we clarify key concepts, correct common misconceptions, and provide a terminological field guide across systems,
