Continuum dynamics of the formation, migration and dissociation of self-locked dislocation structures on parallel slip planes [PDF]

, 2016
In continuum models of dislocations, proper formulations of short-range elastic interactions of dislocations are crucial for capturing various types of dislocation patterns formed in crystalline materials. In this article, the continuum dynamics of straight dislocations distributed on two parallel slip planes is modelled through upscaling the ...

Manipulating the Light Systemic Signal HY5 Greatly Improve Fruit Quality in Tomato

Advanced Science, EarlyView.
This study establishes that HY5, activated by low‐dose light, acts as a systemic signal to enhance tomato fruit quality by directly promoting carotenoid synthesis and sugar metabolism. These findings demonstrate HY5's mobility from leaves to fruits and its application potential through nighttime LED lighting, offering a practical strategy for crop ...

Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics

Advanced Science, EarlyView.
This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...

Can Subscapularis Augmentation Serve as an Alternative to the Remplissage Procedure? A Case Report

Surgeries
When performing surgical treatment for shoulder dislocation, the Remplissage procedure for large Hill-Sachs lesions, which correspond to off-track lesions, has been reported to yield satisfactory results using an arthroscopic approach.

Data-driven Shoulder Inverse Kinematics [PDF]

arXiv, 2016
This paper proposes a shoulder inverse kinematics (IK) technique. Shoulder complex is comprised of the sternum, clavicle, ribs, scapula, humerus, and four joints. The shoulder complex shows specific motion pattern, such as Scapulo humeral rhythm. As a result, if a motion of the shoulder isgenerated without the knowledge of kinesiology, it will be seen ...

Large Built‐in Fields and Tunable Ferroelectricity in Composition‐Graded ScAlN Thin Films Deposited by Reactive Sputtering

Advanced Science, EarlyView.
This study explores composition‐graded ScxAl1‐xN thin films grown by large‐scale and CMOS‐compatible sputtering that can effectively suppress abnormally‐oriented grains. Importantly, their ferroelectric properties can also be tuned owing to large built‐in fields induced by chemical/polarization gradient.

Treatment and outcomes of chronic locked posterior shoulder dislocations: a retrospective case series

BMC Musculoskeletal Disorders, 2023
Background Posterior shoulder dislocations are rare injuries that are often missed on initial presentation. Cases left untreated for more than three weeks are considered chronic, cannot be reduced closely (they become locked) and are usually associated ...

Microplasticity and yielding in crystals with heterogeneous dislocation distribution [PDF]

, 2018
In this study, we use discrete dislocation dynamics (DDD) simulation to investigate the effect of heterogeneous dislocation density on the transition between quasi-elastic deformation and plastic flow in face-centered cubic single crystals. By analyzing the stress-strain curves of samples with an initial, axial dislocation density gradient, we arrive ...
