Soil compaction and stress propagation after different wheeling intensities on a silt soil in South-East Norway

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
The objective of this study was to evaluate the effect of wheeling with two different wheel loads (1.7 and 2.8 Mg) and contrasting wheeling intensities (1x and 10x) on the bearing capacity of a Stagnosol derived from silty alluvial deposits.

Hydro-Physical Properties of a Typic Hapludult under the Effect of Rice Husk Ash

open access: yesRevista Brasileira de Ciência do Solo, 2016
The combustion of rice husk generates a partially burnt mixture called rice husk ash (RHA) that can be used as a source of nutrients to crops and as a conditioner of soil physical properties.

Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 43-55, March 2026.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 2, February 2026.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Nonadiabatic and Anharmonic Effects in High‐Pressure H3S and D3S Superconductors

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
Superconductivity in high‐pressure H3S${\rm H}_3{\rm S}$ and D3S${\rm D}_3{\rm S}$ is studied using first‐principles calculations that include anharmonic lattice dynamics and nonadiabatic electron‐phonon vertex corrections, going beyond the conventional Migdal‐Eliashberg framework. These effects suppress the effective electron–phonon coupling and lower
