Gene expression profiling reveals similarities between the spatial architectures of postnatal articular and growth plate cartilage. [PDF]

open access: yesPLoS ONE, 2014
Articular and growth plate cartilage are discrete tissues but arise from a common cartilaginous condensation and have comparable spatial architectures consisting of distinct layers of chondrocytes.

High efficiency and scalable fabrication of fresnel zone plates using holographic femtosecond pulses

open access: yesNanophotonics, 2022
To meet the growing demand for photonic integration and device miniaturization, planar diffractive Fresnel zone plates (FZPs) are widely applied in integrated optical systems.

Effect of Cone-Plate Clarifier Structure Parameters on Flocculation Efficiency

open access: yesSeparations, 2021
In this study, a coal mine water flocculation system was established. A series of flocculation tests were carried out at different structural parameters (cylinder height, cone-plate insertion depth and cone-plate spacing) to better investigate the effect

New hypothesis to explain Quaternary forearc deformation and the variety of plate boundary earthquakes along the Suruga–Nankai Trough by oblique subduction of undulations on the Philippine Sea Plate

open access: yesEarth, Planets and Space, 2020
Plate-boundary earthquakes of magnitude 8 or greater along the Suruga–Nankai Trough subduction zone have repeated at intervals of 90–150 years, but with widely varying magnitudes and rupture areas.

Cantor dust zone plates

open access: yesOptics Express, 2013
In this paper we use the Cantor Dust to design zone plates based on a two-dimensional fractal for the first time. The pupil function that defines the coined Cantor Dust Zone Plates (CDZPs) can be written as a combination of rectangle functions. Thus CDZPs can be considered as photon sieves with rectangular holes. The axial irradiances produced by CDZPs

Spatial regulation of bone morphogenetic proteins (BMPs) in postnatal articular and growth plate cartilage. [PDF]

open access: yesPLoS ONE, 2017
Articular and growth plate cartilage both arise from condensations of mesenchymal cells, but ultimately develop important histological and functional differences. Each is composed of three layers-the superficial, mid and deep zones of articular cartilage

Zone Plate Interferometer

open access: yesApplied Optics, 1974
A developed form of the Fresnel zone-plate interferometer is described. Three basic configurations are distinguished, associated with the real and virtual first order foci of a zone plate. Related versions and higher order variants are also educed. Compensated phase zone plates used in this application are found to produce uniform amplitude wavefronts.

Electromyography of the muscle spindle

open access: yesScientific Reports, 2022
In needle electromyography, there are two spontaneous waveforms, miniature end plate potentials and “end plate spikes”, appearing usually together.

Bidirectional Loading of the Subduction Interface: Evidence From the Kinematics of Slow Slip Events

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Subduction zones host some of Earth's most damaging natural hazards, including megathrust earthquakes and earthquake‐induced tsunamis. A major control on the initiation and rupture characteristics of subduction megathrust earthquakes is how the coupled ...
