A tipping point for tipping points

Oikos, EarlyView.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

Public perceptions of anthropogenic and natural sounds: Disparities in soundscapes and corresponding sense of place

People and Nature, EarlyView.
Abstract Noise pollution is an environmental stressor negatively affecting humans and biodiversity. Noise pollution is often measured and regulated according to loudness, but in this study, we assessed noise pollution based on human perceptions of soundscapes.

Predictive Assessment of Progressive Damage in Mechanically Fastened Glass–Epoxy Composites

Polymer Composites, EarlyView.
Progressive damage in mechanically fastened glass–epoxy composites. ABSTRACT Ensuring the structural integrity of advanced composites necessitates precise methodologies for forecasting the onset and progression of damage. This research focused on the predicting progressive damage (PD) for riveted joints composite laminates employing a combined ...

Comparative Evaluation of Large Amplitude Oscillatory Shear (LAOS) Analysis Methods for Detecting Surfactant‐Induced Structural Evolution in Xanthan Gum Solutions

Journal of Polymer Science, EarlyView.
A comparative large‐amplitude oscillatory shear analysis reveals how cationic surfactants progressively weaken xanthan gum networks. While conventional rheology identifies network softening, advanced LAOS methods uncover nonlinear deformation mechanisms and transient structural evolution that remain hidden in cycle‐averaged measurements.

Evaluating anisotropy‐based Monin–Obukhov similarity theory over canopies and complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study shows that an anisotropy‐based generalization of Monin–Obukhov surface‐layer scaling (SC23) applies readily across a wide range of atmospheric conditions with variable terrain, canopies, and land‐cover complexity. This work focuses on the scaling of velocity variances for 7 years at the 47 sites in the National Ecological Observation Network
