Repair of heat-damaged RC flat slabs using a hybrid CFRP rope–sheet technique

Results in Engineering
The punching shear behavior for the flat slabs is considered the most important parameter that might be affected when the slab is subjected to elevated temperatures, which makes it important to use a repairing technique for such damaged slabs ...

Fuels Mediate the Influence of Climate Teleconnections on Wildfires in Dryland Ecosystems

Global Change Biology, Volume 31, Issue 8, August 2025.
Climate teleconnections, such as those driven by El Niño–Southern Oscillation (ENSO), modulate regional wildfire activity via the immediate mediating effect of weather and the delayed mediating effect of fuel. We show that in drylands such as Australia, the Horn of Africa, and the northern Middle East, the fuel‐related lagged effect plays a stronger ...

Novel approach for strengthening T-beams deficient in shear with near-surface mounted CFRP ropes in form of closed stirrups

Developments in the Built Environment
Existing reinforced concrete buildings frequently require shear-strengthening to ensure structural integrity, and externally bonded carbon fiber-reinforced polymers (EB-CFRP) have become a wide-applicable approach.

Trialling floral‐baited traps to survey flower‐visiting insects in tropical crops: Findings from an oil palm case study

Entomologia Experimentalis et Applicata, Volume 173, Issue 2, Page 140-155, February 2025.
Monitoring pollinating arthropods in crop systems can provide important information about pollinator populations but can be hampered by accessibility to flowers, or the timing of flowering and pollinator visits. We used oil palm as a case study system to trial a new trap design to survey flower‐visitors of insect‐pollinated crops.

Data‐driven model for seismic assessment, design, and retrofit of structures using explainable artificial intelligence

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 3, Page 281-300, 20 January 2025.
Abstract Retrofitting building designs is crucial given the global aging infrastructure and increased in frequency of natural hazards like earthquakes. While traditional data‐driven models are widely used for predicting building conditions, there has been limited exploration of recent artificial intelligence (AI) techniques in structural design.

Finite Element Performance Assessment of RC Columns Strengthened With Hybrid NSM Steel and FRP Bars Subjected to Static and Repeated Loads

Modelling and Simulation in Engineering, Volume 2025, Issue 1, 2025.
A numerical finite element analysis has been investigated in this paper to examine the performance of strengthened reinforced concrete (RC) columns with near‐surface mounted (NSM) fiber‐reinforced polymer (FRP) and steel bars under static and repeated loads using the finite element software ABAQUS/Standard.

Climatic Predictors of Long‐Distance Migratory Birds Breeding Productivity Across Europe

Global Ecology and Biogeography, Volume 33, Issue 11, November 2024.
ABSTRACT Aim Ongoing climate changes represent a major determinant of demographic processes in many organisms worldwide. Birds, and especially long‐distance migrants, are particularly sensitive to such changes. To better understand these impacts on long‐distance migrants' breeding productivity, we tested three hypotheses focused on (i) the shape of the
