Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 12, Page 2435-2490, December 2026.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Multi‐Vendor and Multi‐Site Characterization of 13C Coils for Clinical Studies

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 6, Page 2885-2893, December 2026.
ABSTRACT Purpose Due to the inherently low signal‐to‐noise ratio (SNR) domain for 13C imaging, optimal coil performance is essential to maximize data quality. Quality control (QC) for 13C coils employed in magnetic resonance spectroscopy (MRS) is of paramount importance.

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3540-3560, November 2026.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Design Internal Forces of Non‐Dissipative Members in CBFs With Regular and Irregular Brace Configurations

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3443-3465, November 2026.
ABSTRACT Steel Concentrically Braced Frames (CBFs) are widely used in seismic regions, with chevron and split‐X configurations commonly adopted for their structural efficiency and architectural flexibility. Although extensive research has been carried out on these systems, the effectiveness of the formulations available in the literature for estimating
