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

open access: yesThe 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).

Distinct neural input strategies to motor units in the soleus and medial gastrocnemius during quiet standing

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Motor unit spike trains were decomposed from high‐density surface electromyograms recorded from the medial gastrocnemius (MG; left, in red) muscle and soleus (SOL; right, in blue). To compare the neural input to the spinal motoneurons between them, we quantified the intramuscular coherence (IMC) of motor unit spike trains within ...

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 3859-3879, December 2026.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Three‐Dimensional Analytical Model of a Podium Structure With Rocking Columns of Square Cross Section

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 4055-4068, December 2026.
ABSTRACT Allowing structural systems to uplift and rock during seismic excitation has emerged as an effective and inherently self‑centering form of seismic isolation. This paper develops a computationally efficient 3D analytical model suitable for the understanding of the behavior of rocking bridges.

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

open access: yesEarthquake 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 ...
