Proposed Diagnostic Reference Levels for Frequently Performed Paediatric Radiographic Examinations

Journal of Medical Radiation Sciences, EarlyView.
Paediatric diagnostic reference levels (DRLs) are weight‐stratified dose levels for typical medical imaging examinations for broadly defined types of equipment. The 75th percentiles of the FRLs across the nine X‐ray units from five centres in Australia were calculated as the proposed Local DRLs (LDRLs).

Evolution of Dynamic Recrystallization in 5CrNiMoV Steel during Hot Forming

Advances in Materials Science and Engineering, 2020
The dynamic recrystallization (DRX) behavior of 5CrNiMoV steel was investigated through hot compression at temperatures of 830–1230°C and strain rates of 0.001–10 s−1.

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, EarlyView.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).

Short‐Range Order and LixTM4−x Probability Maps for Disordered Rocksalt Cathodes

Small, EarlyView.
Monte Carlo mapping with a simplified cluster description framework discloses the origin of Li4${\rm Li}_4$ deficiency and unfavorable short‐range order prevalent in most DRX materials. Statistical mechanical sampling indicates that ordering quantities in the disordered state do not necessarily represent a simple attenuation of their low‐temperature ...

Modeling and simulation of dynamic recrystallization behavior for Q890 steel plate based on plane strain compression tests

Open Physics, 2020
In view that the traditional dynamic recrystallization (DRX) model cannot effectively predict the DRX process in the hot deformation process of sheet metal, DRX behavior modeling and simulation of q890 steel plate based on the plane strain compression ...

Sampling Colourings of the Triangular Lattice [PDF]

, 2010
We show that the Glauber dynamics on proper 9-colourings of the triangular lattice is rapidly mixing, which allows for efficient sampling. Consequently, there is a fully polynomial randomised approximation scheme (FPRAS) for counting proper 9-colourings ...

AstroECP: towards more practical electron channeling contrast imaging

Journal of Applied Crystallography, EarlyView.
We explore and address many of the major challenges associated with using electron channeling contrast imaging in a scanning electron microscope, with the goal of more easily revealing and characterizing crystalline defects such as dislocations.Electron channeling contrast imaging (ECCI) is a scanning electron microscope based technique which enables ...

A critical assessment of experimental investigation of dynamic recrystallization of metallic materials

Materials & Design, 2020
Dynamic recrystallization (DRX) often takes place during hot deformation of metallic materials, which then exerts significant influence on the final microstructures and mechanical properties of the formed components.
