Enhancing mechanical and tribological properties of laser-based directed energy deposited IN718 alloy via synchronised high repetition laser shock peening

Virtual and Physical Prototyping
Laser-based direct energy deposition (LDED) has been restricted by unavoidable defects and poor mechanical performance. This study proposes synchronised high repetition laser shock peening (HRLSP) to modify the mechanical and tribological properties of ...

Dynamic Peierls-Nabarro equations for elastically isotropic crystals

, 2010
The dynamic generalization of the Peierls-Nabarro equation for dislocations cores in an isotropic elastic medium is derived for screw, and edge dislocations of the `glide' and `climb' type, by means of Mura's eigenstrains method.

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Modelling of dislocation generation and interaction during high-speed deformation of metals

, 2000
Recent experiments by Kiritani et al. have revealed a surprisingly high rate of vacancy production during high-speed deformation of thin foils of fcc metals. Virtually no dislocations are seen after the deformation.

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

Evolution of tribo-magnetization during sliding of ferromagnetic materials

Friction
Sliding-induced subsurface microstructure evolution is believed to be decisive for determining the friction and wear performance of metallic contacts as well as the development of tribo-magnetization.

Fatigue crack growth characteristics of Fe and Ni under cyclic loading using a quasi-continuum method

Beilstein Journal of Nanotechnology, 2018
A quasi-continuum (QC) method based on the embedded atom method (EAM) potential was employed to investigate the fatigue crack growth and expansion characteristics of single-crystal Fe and Ni under cyclic loading modes I and II.

Brainstem and Cerebellar Volume Loss and Associated Clinical Features in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Progressive Supranuclear Palsy (PSP) is a neurodegenerative ‘tauopathy’ with predominating pathology in the basal ganglia and midbrain. Caudal tau spread frequently implicates the cerebellum; however, the pattern of atrophy remains equivocal.

Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics

Advanced Science
MXenes are a family of two‐dimensional (2D) transition metal carbides, nitrides, and carbonitrides with potential applications in ceramics and composites due to their nanometer‐thick morphology, hydrophilic surfaces, and negative zeta potentials. In this
