The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, Volume 33, Issue 4, Page 1256-1284, August 2026.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

An Investigation into the Liquefaction Phenomena in the Iskenderun Bay Following the February 6 Kahramanmaraş Earthquake

Journal of Advanced Research in Natural and Applied Sciences
This study investigates the liquefaction phenomena in the İskenderun Bay by revisiting the site that was liquefied during the first major strike of the Kahramanmaraş earthquake events on February 6th, 2023 (with a moment magnitude of 7.7).

Seismic Risk of Critical Transport Systems: Sensitivity Analysis of the Campania Railway Network to Bradyseism's Features

Risk Analysis, Volume 46, Issue 8, August 2026.
ABSTRACT This study examines the impact of epistemic uncertainties on the seismic risk of a critical transport system, the Campania railway network, during the ongoing bradyseismic unrest at Campi Flegrei, south of Italy. Seismic risk is quantified as the length of the railway requiring post‐event inspection, an operational proxy for service disruption.

Influence of Shaking Sequence on Liquefaction Resistance and Shear Modulus of Sand Through Shaking Table Tests

Geosciences
Case histories have shown that the liquefaction behavior of soils can differ depending on the pre-seismic history of sites. Assessing the shear modulus in soils subjected to seismic events is critical for advancing the fundamental understanding of soil ...

Numerical modeling of wave-induced liquefaction around a gravity-based structure

Frontiers in Built Environment
Residual liquefaction, a significant issue in marine engineering, results from accumulated pore-water pressure in the seabed due to cyclic shear stresses, which compromises soil stability.

Sequential Evolution of Residual Liquefaction in a Silty Seabed: Effect of Wave-Loading History

Journal of Marine Science and Engineering
Multiple liquefaction events may occur if a seabed is subjected to repeated but intermittent wave loadings. This study aimed to investigate the influence of the wave-loading history on the evolution of residual liquefaction in a silty seabed through a ...

Vulnerability of Baghdad Soil to Liquefaction (Numerical Study)

Tikrit Journal of Engineering Sciences
A phenomenon known as "earthquake liquefaction" or "soil liquefaction" occurs when a mass of saturated soil gradually loses strength as a result of increased excess pore water pressure generated by ground shaking during a strong earthquake.

Shaking Table Test on Dynamic Response of Pile Foundations in Liquefiable Sites

工程科学与技术
ObjectiveSeismic damage investigations from recent strong earthquakes have demonstrated that soil liquefaction can induce complex and diverse failure modes in pile foundations, including excessive lateral displacement, bending failure, and post ...
