A Novel Permutation Entropy–Based Method for Assessing the Stability of Seawalls on Soft Soils

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Evaluating the stability of seawalls constructed on soft soils is critical but challenging. Traditional methods often depend on whether settlement velocity exceeds predefined thresholds, which can overlook subtle settlement fluctuations and may be less adaptable to varying construction and environmental conditions.

Compactação de solos cultivados com cana-de-açúcar: I -modelagem e quantificação da compactação adicional após as operações de colheita Compaction of soils cultivated with sugarcane: I - modeling and quantification of the additional soil compaction after harvest operations

Engenharia Agrícola, 2010
A colheita mecanizada da cana-de-açúcar, quando realizada em épocas da safra em que o solo se encontra com conteúdos inadequados de água, tem sido responsável pela compactação do solo e a redução da produtividade nos ciclos posteriores da cultura.

Localized Energy Absorption through LaB6 Surface Modification of PA12 Enables Enhanced Tensile Performance in Diode Laser PBF‐LB

Chemistry–Methods, Volume 5, Issue 12, November 2025.
LaB6 surface modification of PA12 enables efficient NIR diode laser PBF‐LB processing, with enhanced tensile strength and tailored microstructures achieved at minimal additionaly energy. By reducing the need for high filler content, this approach expands the options and performance levels of advanced industrial‐grade polymer additive manufacturing. The

Improving Constitutive Modelling of Soft Organic Clays With New Experimental Insight

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 18, Page 4480-4501, 25 December 2025.
ABSTRACT The engineering response of soft organic clays is controlled by anisotropy, stress history and the nature of organic matter. The behaviour of these soils has been investigated extensively over compression triaxial paths, and models are available to successfully reproduce available experimental observations. However, open questions remain about

Strength, Hydraulic, and Microstructural Characteristics of Expansive Soils Incorporating Marble Dust and Rice Husk Ash

Advances in Civil Engineering, 2021
Expansive/swell-shrink soils exhibit high plasticity and low strength, which lead to settlement and instability of lightly loaded structures. These problematic soils contain various swelling clay minerals that are unsuitable for engineering requirements.

Modelling Wetting Collapse, Failure and Deposition of an Unsaturated Slope With Material Point Method

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 18, Page 4526-4551, 25 December 2025.
ABSTRACT The paper presents the modelling of unsaturated soils with the material point method (MPM), including the effect of wetting leading to the loss of strength and the volumetric collapse. The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an ...

How Compressible Are Salt Marshes? Unique Field Experiments Combined With Advanced Modeling Provide Novel Insights From the Venice Lagoon

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Coastal depositional environments, particularly salt marshes, are among the morphologies most vulnerable to relative sea‐level rise (RSLR). Their ability to withstand changing conditions is closely related to their capacity to accrete sediment, gaining elevation at a rate comparable to RSLR. Sedimentation, decomposition of organic remains, and
