Multimodal remote sensing image registration is a fundamental step for multisource data fusion and geospatial analysis. However, nonlinear radiometric, textural, and geometric discrepancies across modalities challenge in...

Abstract Irregular honeycomb structures occur abundantly in nature and in man-made products, and are an active area of research. In this paper, according to the optimization of regular honeycomb structures, two types of ...

In the paper InAs spherical quantum dots in a GaAs matrix were investigated. The energies of electrons and holes in single- and multi-band models (with strong, weak, and intermediate spin-orbit interaction) were calculat...

The sealed loading environment during the compaction process prevents the mechanical behavior of cyclotetramethylenetetranitramine (HMX) under compression from being fully understood. Elucidating the mechanical behavior ...

Sea ice fracture is a time-dependent process in which viscous relaxation delays the onset of cracking in the short term, but accumulated deformation and energy dissipation over long loading times can still lead to fractu...

Abstract The simulation and planning system (SPS) requires accurate and real-time feedback regarding the deformation of soft tissues during the needle insertion procedure. Traditional mechanical-based models such as the ...

Abstract A decrease in the weight of aerospace vehicles, large ships, weapons, and high-speed trains will increase the demand for wide-width magnesium alloy plates and their composite parts to replace steel and plastic. ...

This study investigates deterministic structures in statistical functionals derived from high-resolution measurements of Lake Baikal ice cover deformations preceding ice shocks - events caused by thermal expansion during...

Accurate deformation forecasting is essential for concrete dam safety monitoring, yet real-world deformation series are often nonlinear, nonstationary, and contaminated by noise, missing values, and outliers, which limit...

We study deformation theory of mod p Galois representations of p-adic fields with values in generalised reductive group schemes, such as L-groups and C-groups. We show that the corresponding deformation rings are complet...

Abstract We construct bi- and uni-vector deformations of 10d heterotic supergravity solutions with the gauged double field theory approach. We construct a generalization of the “open/closed” map for this case and con...

With the application of a linear theory of elasticity of anisotropic crystals and the use of experimental values of elastic moduli Сij and compliances Sij given in the Landolt-Börstein tables, characteristic surfaces o...

Laminate composites offer an effective strategy to overcome strength-ductility trade-off by harnessing the synergistic properties of constituent metals. In the TA1/304 steel composite, a unique nano-scale heterostructure...

With the advancement in understanding of the physics inside chaotic systems, chaos has been harnessed from a nuisance to a beneficial factor in optical devices. Light–matter interaction in chaotic systems has been util...

The article presents the results of an experimental and theoretical study of the prediction of deflections of timber beams made of three types of wood: massive, glued laminated, and cross-laminated timber. The aim of the...

Wood is a natural material widely used in construction. Unlike artificial building materials, wood is characterized by natural defects (flaws) that can negatively affect its performance under load. This study proposes a ...

While heterostructured materials leveraging both continuous and discontinuous precipitation have been developed to enhance the mechanical properties of L12-strengthened high-entropy alloys, the pivotal role of the hard-t...

Powder compaction is the most widely used technology to fabricate polymer bonded explosives (PBX), and its parameters significantly influence the structures and mechanical properties of the final products. By conducting ...

Abstract To satisfy the requirements for the precise formation of large-scale high-performance lightweight components with inner ring reinforcement, a new multidirectional loading rotary extrusion forming technology is d...

SiC reinforced aluminum matrix composites (AMCs) are widely employed in various fields, and great importance has been attached to SiC/Al interface. Here, SiC/2009Al AMCs are fabricated for further research into SiC/Al in...

The simultaneous determination of adhesion and deformability parameters of erythrocytes was carried out through a microfluidic device, which uses an inverted optical microscope with new image acquisition and analysis tec...

The sector of the Andes studied in this paper (33°30′-33°45′S) presents a key region to study the relationship between tectonic setting and deformation history in a transitional zone between flat (north of 33°S) a...

The Paleozoic evolution of Patagonia was the focus of controversies between its allochthonous or autochthonous origin. The arrival of plate tectonics supported new allochthonous alternatives and from an initial fixist re...

It has been shown that rolling an Fe–15Mn–5Si–9Cr–5Ni (wt.%) alloy at 800 °C followed by annealing at 650 °C gives a structure – a high density of stacking faults and enough austenite hardness – that promot...
