What Future Lies Ahead for Circular Business Models Research?

Strategic Change, EarlyView.
ABSTRACT The circular economy—wherein waste is designed out, materials are circulated and nature is regenerated—has reached global recognition. From policy to business circles, it is seen as a viable strategy to address multiple societal grand challenges—including climate change and depletion of finite natural resources—and build a more resilient ...

Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

Limnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...
