Tri-axial Self-centering Reinforced Concrete Frame and Its Quasi-static Test

工程科学与技术, 2018
Self-centering reinforced concrete frame is a new type of earthquake resilient structure.Comparing to conventional RC structures,self-centering structure is known for its minimal damage under earthquakes and little residual deformation after earthquakes ...

Impact of Sleep on Glucose Metabolism in Individuals With Overweight or Obesity: A Systematic Review

Obesity Reviews, EarlyView.
ABSTRACT Introduction The obesity epidemic has coincided with chronic sleep deprivation. Sleep disturbances may contribute to metabolic dysfunction in individuals with BMI ≥ 25 kg/m2. This review investigates associations between sleep patterns and glucose metabolism in this population.

Beyond Directions: Symmetry‐Aware Rotation Sets for Triaxial Diffusion Encoding by Geometric Filter Optimization

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2489-2504, November 2026.
ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations). Based on this, we propose a method to

Comparison of Mesoscale Crack Advance and Process Zone Element Approaches for Simulating Ductile Crack Trajectories in Steel

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 11, Page 4850-4862, November 2026.
ABSTRACT Rigorous application of continuum damage mechanics (CDM) models coupled with crack propagation schemes can predict crack branching or zigzag trajectories near the crack tip, even when the macroscopic crack growth is straight. This arises from oscillations in the local damage field and is consistent with experimental observations of ductile ...

Fracture Modeling of Nearly Incompressible Hyperelastic Materials: A Phase‐Field Approach via Simo–Taylor–Pister Three‐Field Variation

International Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.
ABSTRACT Incompressibility is commonly observed in the majority of hyperelastic materials, which are fundamental to a wide range of technical applications owing to their distinctive properties, particularly their flexibility, stretchability, and resilience.
