A rapid strengthening approach for existing A-type RC frames in substations considering low disturbance: a finite-element-driven design study

open access: yesFrontiers in Materials
The power system is an important lifeline engineering system, and substations play a crucial role in transferring the power supply. To ensure the reliability of the power supply, the safety of the existing A-type reinforced concrete frame cannot be ...

Multimodal Wearable Biosensing Meets Multidomain AI: A Pathway to Decentralized Healthcare

open access: yesAdvanced Science, EarlyView.
Multimodal biosensing meets multidomain AI. Wearable biosensors capture complementary biochemical and physiological signals, while cross‐device, population‐aware learning aligns noisy, heterogeneous streams. This Review distills key sensing modalities, fusion and calibration strategies, and privacy‐preserving deployment pathways that transform ...

A model to simulate the cyclic axial compressive behavior of RC columns confined with CFRP sheets [PDF]

open access: yes, 2008
In the present work a constitutive model to predict the cyclic axial compressive behavior of RC columns confined with CFRP is proposed. This model was implemented in a FEM-based computer program, able to simulate the material nonlinear behavior of ...

Effect of steel reinforcement with different degree of corrosion on degeneration of mechanical performance of reinforced concrete frame joints [PDF]

open access: yesFracture and Structural Integrity, 2016
Beam-column joints which shoulders high-level and vertical shearing effect that maintains balance of beam and column end is the major component influencing the performance of the whole framework.

FRP strengthening of RC walls with openings [PDF]

open access: yes, 2009
Strengthening reinforced concrete (RC) walls with openings using fibre reinforced polymers (FRP) has been proved experimentally to be a viable rehabilitation method. However, very few theoretical investigations are reported.

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

An Economic Comparison between Using Concrete and Steel Frames in a Medium MultiStory Building in Iraq

open access: yesTikrit Journal of Engineering Sciences
Building materials have always played essential roles in construction assessment, and cost calculation is important in selecting appropriate materials. Reinforced concrete and steel materials are usually used to construct multistory building structures.

Schooling Trajectories and the Development of Brain Dynamics: A Comparative Study of Montessori and Traditional Education

open access: yesAdvanced Science, EarlyView.
We investigate whether Montessori and traditional schooling systems shape the developmental trajectory of large‐scale brain dynamics in different ways. We quantify the arrow of time (“non‐reversibility”) in neural activity during resting state and movie‐watching, revealing distinct maturational patterns.
