Regeneration failure, fire, topography, and climate interact to drive temperate wet forest landscapes into fire traps

open access: yesEcography, EarlyView.
Where early successional forests are more flammable than old‐growth forests, forested landscapes are vulnerable to shifting into ‘fire traps' through positive feedbacks, where fire leads to more fire. These feedbacks are amplified by increased flammability driven by climate change, the presence of non‐native flammable plant species, and slowed ...

Analytical Framework for System‐Level Fragility Surfaces of Reinforced Concrete Bridges Under Mainshock‐Aftershock Sequences

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.

On the existence of Hamiltonian cycles in hypercubes [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Building on the results of our previous work on Euclidean leaper tours, considering all integers k>1 and h>0, we study the existence of Hamiltonian cycles in the vertex set C(2,k):={0,1}ᵏ of the k-dimensional hypercube when the Euclidean distance between

Inter‐Material Transfer Learning for Accelerated Nanofluid Heat Transfer Prediction: A Machine Learning Approach for Energy Systems

open access: yesEnergy Science &Engineering, EarlyView.
This study presents an inter‐material transfer learning framework for nanofluid heat transfer prediction in energy systems. By leveraging knowledge from Al2O3‐water data, the model accurately predicts hybrid Al2O3‐TiO2 nanofluid performance with only 20 simulations, achieving R2 = 0.985 and reducing computational requirements by 78.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

open access: yesFire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.
