Feeling Better Before, Not After: An Ecological Momentary Assessment of Affect Around Exercise in Women With Eating Disorders

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Maladaptive exercise includes excessive, compulsive, or compensatory exercise and is a common eating‐disorder (ED) symptom associated with increased severity, slower rates‐of‐recovery, and faster rates‐of‐relapse. Affect‐regulation theories posit that maladaptive exercise functions to reduce high negative affect (NA), although ...

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Learning Rocking Dynamics From Sparse Shake‐Table Data With Interpretable Physics‐Informed Neural Networks

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We present a hybrid interpretable Physics‐Informed Neural Network Long‐Short Term Memory (Hybrid PINN LSTM) framework for predicting the seismic response of rocking blocks. Existing analytical models rely on uncertain idealizations, while purely data‐driven and machine‐learning approaches lack physical consistency and interpretability.

Seismic Performance and Vibration‐Based Damage Identification of Two‐Storey Balloon‐Framed CLT Shear Walls

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT While cross‐laminated timber (CLT) is increasingly utilized in lateral force‐resisting systems in mass timber construction, research has predominantly focused on platform‐type construction. Balloon‐type CLT shear wall systems offer distinct structural advantages, notably the elimination of cumulative perpendicular‐to‐grain compression and a ...

Rocking and Rolling of Rigid Polygons Under Seismic Excitation

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We present an event driven analytical framework for rigid cyclic polygons subjected to horizontal ground excitation in which uplift, impact, and successive pivot switching are treated within a unified non‐smooth dynamical description. Rolling is defined as a sequence of energetically admissible transitions between neighbouring vertices tied to

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Numerical Simulation Study on Optimization of Horizontal Sublevel Top‐Coal Caving Mining Technique for Steeply Inclined Extra‐Thick Coal Seam

open access: yesEnergy Science &Engineering, EarlyView.
As the sublevel height increases, the top‐coal recovery amount gradually increases, but both the top‐coal recovery rate and the thickened top‐coal recovery rate show a downward trend, and the decline in the top‐coal recovery rate is gradually increasing. The comparison indicates that the optimal sublevel height is 20 m.
