In vivo imaging of cellular proliferation in colorectal cancer using positron emission tomography
, 2003 Background and aims: Positron emission tomography (PET) using 18F labelled 2-fluoro-2-deoxy-D-glucose (18FDG) is an established imaging tool, although the recent development of a biologically stable thymidine analogue [18F] 3'-deoxy-3-fluorothymidine ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Positron Ring Cameras for Emission-Computed Tomography [PDF]
IEEE Transactions on Nuclear Science, 1977 A properly designed circular ring of NaI(Tl) crystals and suitable reconstruction algorithms can provide rapid, high-resolution transverse section images of positron-labeled compounds in the human body. The spatial resolution is limited by the crystal center-to-center spacing and by the positron range in tissue.

Models for the PET quantitative imaging of the adenosine receptor radioligand [11C] SCH442416 in humans [PDF]
, 2010 Positron Emission Tomography is an important imaging technique, that enables regional function to be assayed in a fully quantitative and noninvasive manner. It is based on the use of radioactive tracers: [11C]SCH442416, which is the compound of interest

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.
