A TEM, STEM and backscattered electron channeling imaging study of martensite formation in Co-19.6Fe
A high purity, C-free Co-19.6Fe alloy is shown to undergo a variety of martensitic and bainitic reactions.
TEM, STEM and back-scattered electron channelling patterns and images have been used to study the effects of ageing at temperatures below the α solvus and of grain boundary misorientation on the occurrence of martensitic transformation in the adjacent grains and on the nature of their product
Reply to "Comment on 'A linear optics implementation of weak values in Hardy's paradox'"
The comment by Lundeen et al. contains two criticisms of our proposal. While
we agree that the state-preparation procedure could be replaced by a simpler
setup as proposed by the authors of the comment, we do not agree with the
authors on their second, and more important point regarding two-particle weak
measurements. We believe this to be the result of a misunderstanding of our
original paper.Comment: 2 pages, accepted in PR

Linear optics implementation of weak values in Hardy's paradox
We propose an experimental setup for the implementation of weak measurements
in the context of the gedankenexperiment known as Hardy's Paradox. As Aharonov
et al. showed, these weak values form a language with which the paradox can be
resolved. Our analysis shows that this language is indeed consistent and
experimentally testable. It also reveals exactly how a combination of weak
values can give rise to an apparently paradoxical result.Comment: 4 pages, accepted by PR

Identifiability of generalised Randles circuit models
The Randles circuit (including a parallel resistor and capacitor in series
with another resistor) and its generalised topology have widely been employed
in electrochemical energy storage systems such as batteries, fuel cells and
supercapacitors, also in biomedical engineering, for example, to model the
electrode-tissue interface in electroencephalography and baroreceptor dynamics.
This paper studies identifiability of generalised Randles circuit models, that
is, whether the model parameters can be estimated uniquely from the
input-output data. It is shown that generalised Randles circuit models are
structurally locally identifiable. The condition that makes the model structure
globally identifiable is then discussed. Finally, the estimation accuracy is
evaluated through extensive simulations
Work-based training and job prospects for the unemployed: an evaluation of training for work
"Training for Work (TfW) was a major DfEE programme aimed at helping people who had been claimant unemployed for over six months to find jobs and improve their skills, by providing appropriate training and work experience. After initial assessment and guidance, entrants took one of three main routes: employer placements (with either trainee or employed status), full-time off-the-job training, or project placements... A nationally representative sample of TfW participants in England and Wales who left TfW during the autumn of 1995 was interviewed in spring 1996 and a second time in summer 1997. The present analysis excluded those who had been unemployed for less than six months at the point of entry to the programme (the 'special needs' group)." - Page 1
Which point sets admit a k-angulation?
For k >= 3, a k-angulation is a 2-connected plane graph in which every
internal face is a k-gon. We say that a point set P admits a plane graph G if
there is a straight-line drawing of G that maps V(G) onto P and has the same
facial cycles and outer face as G. We investigate the conditions under which a
point set P admits a k-angulation and find that, for sets containing at least
2k^2 points, the only obstructions are those that follow from Euler's formula.Comment: 13 pages, 7 figure
Thoughts on Barnette's Conjecture
We prove a new sufficient condition for a cubic 3-connected planar graph to
be Hamiltonian. This condition is most easily described as a property of the
dual graph. Let be a planar triangulation. Then the dual is a cubic
3-connected planar graph, and is bipartite if and only if is
Eulerian. We prove that if the vertices of are (improperly) coloured blue
and red, such that the blue vertices cover the faces of , there is no blue
cycle, and every red cycle contains a vertex of degree at most 4, then is
Hamiltonian.
This result implies the following special case of Barnette's Conjecture: if
is an Eulerian planar triangulation, whose vertices are properly coloured
blue, red and green, such that every red-green cycle contains a vertex of
degree 4, then is Hamiltonian. Our final result highlights the
limitations of using a proper colouring of as a starting point for proving
Barnette's Conjecture. We also explain related results on Barnette's Conjecture
that were obtained by Kelmans and for which detailed self-contained proofs have
not been published.Comment: 12 pages, 7 figure
