'Yu Zou'] Dislocation motion, an important mechanism underlying crystal plasticity, is critical for the hardening, processing, and application of a wide range of structural and functional materials. For decades, the movement of dislocations has been widely observed in crystalline solids under mechanical loading.…

We revisit some recents results inspired by the Peierls-Nabarro model on edge dislocations for crystals which rely on the fractional Laplace representation of the corresponding equation. In particular, we discuss results related to heteroclinic, homoclinic and multibump patterns for the atom dislocation function, the…

modes Authors: ['Long-Zhou Huang' 'Yun-Jiang Wang' 'Matteo Baggioli'] Because of the inevitably disordered background, structural defects are not well-defined concepts in amorphous solids. In order to overcome this difficulty, it has been recently proposed that topological defects can be still identified in the pattern…

'Gabrielle Dykhouse' 'Taylor J Manes' 'Phillip C McKegg' 'Cameron J Sabet' 'Brett Barthman' 'Robert Golden'] Introduction Hip dislocations are devastating injuries that require urgent intervention to minimize the development of severe complications. This study aimed to evaluate the epidemiology of hip dislocations in…

'Yukihide Nishimura' 'Daisuke Nishiyama' 'Hiroshi Yamada' 'Ken Kouda'] Most previous studies on dislocation after total hip arthroplasty (THA) have focused on patient- and surgery-related factors without detailing the specific circumstances of dislocation events. Therefore, this study aimed to analyze dislocation cases…

'Zhijian Yang' 'Yejun Gu' 'Yang Xiang'] Dislocation climb plays an important role in understanding plastic deformation of metallic materials at high temperature. In this paper, we present a continuum formulation for dislocation climb velocity based on densities of dislocations. The obtained continuum formulation is an…

dislocations and wedge disclinations Authors: ['Shunsuke Kobayashi' 'Katsumi Takemasa' 'Ryuichi Tarumi'] This study presents a comprehensive mathematical model for Volterra defects and explores their relations using differential geometry on Riemann–Cartan manifolds. Following the standard Volterra process, we derived…

Rationale: Ipsilateral simultaneous shoulder and elbow dislocations are rare and complex injuries. Only a few case reports have been published in the literature. Therefore, little is known about the mechanism of injury and its treatment. Patient concerns: An 83-year-old woman presented with severe pain in the right…

Identifying the regions responsible for plastic flow in amorphous solids remains an open problem, since structural disorder seems to prevent the direct application of concepts such as dislocations, topological defects that successfully describe irreversible deformations in crystalline systems. Here, we introduce fields…

'John P Scanaliato' 'Annette H Yoon' 'Morgan R Askew' 'Kyle J Klahs' 'John C Dunn' 'Nata Parnes'] Background Elbows are one of the most frequently dislocated large joints; however, there is limited epidemiological data, especially during the coronavirus disease 2019 (COVID-19) pandemic. This study characterizes elbow…

Background Glenohumeral dislocation combined with fracture of the proximal humerus is extremely rare in children, and this study aims to investigate its incidence in the pediatric population and review the treatment strategy for this condition. Methods Between Jan 2014 and Jan 2019, 280 patients with unilateral…

Hydrogen embrittlement severely degrades mechanical properties of austenitic stainless steels (γ-SS), yet the bulk deformation microstructures responsible for this phenomenon have not been directly observed. While the internal microstructure is essential to define metal plasticity, deformation, and fracture, no…

(1) Background: The true dislocation incidence following THA is difficult to ascertain in population-based cohorts. In this study, we explored the cumulative dislocation incidence (CDI), the relationship between the incidence of dislocation and revision surgery, patient- and surgery-related factors in patients…

Solid-state Li-ion batteries, utilizing Ni-rich oxide cathodes, hold promise for high-energy electrochemical storage. However, Li intercalation-induced dimensional changes can lead to crystal defect formation in these cathodes, and contact mechanics problems between cathode and solid electrolyte. Understanding the…

The dynamics of a system of particles subject to a 4th order potential field modeling the space-time evolution of wedge disclinations is studied, focusing on finite systems of disclinations within a circular domain. Existence theorems for the trajectories of these disclinations are presented, considering both the…

Plant cell growth depends on slow, irreversible creep of the fibrous cell wall stretched by turgor, yet the mechanics of creep—and how it differs from elasto-plastic deformation—remains uncertain^1–3^. Using multiscale modeling, we show how wall creep emerges from elementary sliding of cellulose microfibrils along…

Kinesin-1 is a dynamic heterotetrameric assembly of two heavy and two light chains (KHC and KLC) that mediates microtubule-based intracellular transport of many different cargoes. The complex adopts a compact, autoinhibited state that is activated by cargo-adaptor proteins containing specific short linear peptide…
