Mechanical and Metallurgical Evaluation of Four Rotary Nickel‐Titanium File Systems: A Multimethod Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim To compare four rotary nickel‐titanium (NiTi) file systems (Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo) using a multimethod approach to evaluate their mechanical and metallurgical properties. Materials and Methods Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo (all size 25/0.06 with an S‐shaped cross‐section; 52 instruments

Humidity‐driven shape morphing enhances fog harvesting in porous cactus spines

New Phytologist, EarlyView.
Spine straightening and water collection during fog exposure in Turbinicarpus alonsoi. Summary Cacti develop spines instead of conventional leaves, which often serve as mechanical defence against herbivores. However, some cactus species grow porous and flexible spines, suggesting fundamentally different functions.

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 3796-3817, December 2026.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Lateral-torsional buckling of vertically layered composite beams with interlayer slip under uniform moment

, 2012
International audienceThe lateral-torsional stability of vertically layered composite beams with interlayer slip is investigated in this paper, based on a variational approach. Vertically layered elements are typically used in timber engineering but also

Enhancing the Seismic Resilience of Masonry‐Infilled RC Structures Using Rubber Joints: Full‐Scale 3D Shaking Table Tests

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 4088-4112, December 2026.
ABSTRACT Masonry infills in reinforced concrete (RC) frames are highly vulnerable to seismic damage, often sustaining severe cracking even under moderate ground motion, which in turn leads to considerable economic losses and safety risks. To address this issue, this study experimentally evaluates the effectiveness of two innovative rubber‐based joints ...

Direction‐Aware Period Prediction for Seismic Risk Assessment and Application to an Urban Tall Building Portfolio in China

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 4113-4136, December 2026.
ABSTRACT Reliable estimation of the principal periods is essential for regional seismic risk assessment (RSRA) of urban building portfolios. For tall buildings, however, existing period‐prediction formulas are constrained by the lack of representative data, while building translational azimuths are neglected despite their importance for regional ...
