Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

The Local Colocation Patterns of Crime and Land-Use Features in Wuhan, China

ISPRS International Journal of Geo-Information, 2017
Most studies of spatial colocation patterns of crime and land-use features in geographical information science and environmental criminology employ global measures, potentially obscuring spatial inhomogeneity. This study investigated the relationships of

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Effect of relaxation processes on stark echo intensity in the presence of nonresonant laser pulses with spatial inhomogeneity [PDF]

, 2013
We have studied the dependence of the intensity and appearance time of the Stark echo response on the ratio of the field strengths of nonresonant laser pulses with spatial inhomogeneity.

A Novel Framework for Accurate Segmentation of Brain Tumor Using Multiple Kernel Fuzzy Clustering Algorithm

Applied Medical Informatics, 2020
Magnetic Resonance Imaging (MRI) is one of the prominent imaging techniques for assessment of brain tumor progression. Intensity inhomogeneity, partial volume effect (PVE) and diverse nature of tumor render a challenging task for automatic segmentation ...

Distinct Lasing Operation From Chirped InAs/InP Quantum-Dash Laser

IEEE Photonics Journal, 2013
We study the enhanced inhomogeneity across the InAs quantum-dash (Qdash) layers by incorporating a chirped AlGaInAs barrier thickness in the InAs/InP laser structure.

Segmentation of ultrasound B-mode images with intensity inhomogeneity correction

IEEE Transactions on Medical Imaging, 2002
Displayed ultrasound (US) B-mode images often exhibit tissue intensity inhomogeneities dominated by nonuniform beam attenuation within the body. This is a major problem for intensity-based, automatic segmentation of video-intensity images because conventional threshold-based or intensity-statistic-based approaches do not work well in the presence of ...

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

Advanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Finite matrix crack penetrating a partially debonded circular inhomogeneity

Archives of Mechanics, 2012
We rigorously solve the problem of a finite matrix crack penetrating a partially debonded circular elastic inhomogeneity under longitudinal shear. The tips of the matrix crack are mutual image points with respect to the inhomogeneity/matrix interface and
