Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1179-1202, May 2026.
ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.

Comparison of Enamel, Dentin, and the Dentin–Enamel Junction in Horse, Dog, Wild Boar, and Macaque Using Confocal Raman Microscopy

Journal of Raman Spectroscopy, Volume 57, Issue 5, Page 871-878, May 2026.
Confocal Raman microscopy was used to map the dentin–enamel junction (DEJ) across four mammalian species. Chemical maps highlighted variations in mineral (phosphate/carbonate) and organic (amide/CH) phase. These results provide a comparative Raman framework to link tooth microchemistry with species‐specific structure and function.

Reliable Estimation of Wavenumbers for Calcite Peaks

Journal of Raman Spectroscopy, Volume 57, Issue 5, Page 821-827, May 2026.
The wavenumbers of the calcite peaks were accurately estimated using a combination of a He–Ne laser and Ne emission lines. The values following the ± symbol represent the expanded uncertainties, corresponding to an approximate 95% confidence interval. ABSTRACT The Raman‐shift wavenumber ( ∆ν~), which is calculated as the difference between the absolute

Magnetic Properties of Ferritin at Different Levels of Degradation: Implications for MRI‐Based Iron Quantification in the Brain

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2892-2897, May 2026.
ABSTRACT Purpose Ferritin's iron core exhibits complex magnetic properties, as suggested by magnetometry and Mössbauer spectroscopy, which remain incompletely understood. In particular, the antiferromagnetic inner core could influence the accuracy of iron quantification using MRI and raise concerns about postmortem validation studies involving degraded

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Effects of Hold Time on the Elevated Temperature Fatigue Crack Growth Behavior of Alloy 247LC‐DS

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1794-1808, May 2026.
ABSTRACT Creep–fatigue crack growth (CFCG) experiments were performed at 850°C and 950°C on nominally 12.70‐mm‐thick compact‐type specimens of alloy 247LC‐DS, a Ni‐base superalloy. The loading cycles consisted of trapezoidal waveforms with hold times of 2 and 20 min at the maximum force.
