Exploring experiences of externalising and the anorexic voice
Part A
This review synthesised literature exploring people with anorexia nervosa’s (PwAN's), carers' and clinicians' experiences of therapeutic externalisation. Relevant literature was discovered using a systematic search of online databases which found 18 papers that met inclusion criteria. Meta-ethnography was used to synthesise the literature. Findings highlighted stakeholders' contradictory views on the impact of externalisation on PwAN's relationships and sense of identity, indicating that this technique has the potential to help or harm PwAN's recovery. Ways of understanding these contradictory views and the need for clinicians to adapt externalising techniques were emphasised. Review limitations, clinical implications and future research needs are outlined.
Part B
This qualitative study explored carers’ perceptions of the anorexic voice (ANV). Thirteen participants were interviewed, and their transcripts interpreted using Reflexive Thematic Analysis. Findings revealed that the ANV holds many meanings, and the construct attracted advocates and critics among carers. Advocates recognised the ANV as a powerful bully and found they could bring positive changes by altering their relationship with it. Carers outlined benefits, shortcomings and criticisms of the ANV, which under scrutiny, revealed significant overlap with perspectives on externalising. These findings are outlined in the context of existing literature, and the limitations, clinical implications and future directions are illustrated
Using modular decomposition technique to solve the maximum clique problem
In this article we use the modular decomposition technique for exact solving
the weighted maximum clique problem. Our algorithm takes the modular
decomposition tree from the paper of Tedder et. al. and finds solution
recursively. Also, we propose algorithms to construct graphs with modules. We
show some interesting results, comparing our solution with Ostergard's
algorithm on DIMACS benchmarks and on generated graph
Recent Load Calibrations Experience with the YF-12 Airplane
The use of calibrated strain gages to measure wing loads on the YF-12A airplane is discussed as well as structural configurations relative to the thermal environment and resulting thermal stresses. A thermal calibration of the YF-12A is described to illustrate how contaminating thermal effects can be removed from loads equations. The relationship between ground load calibrations and flight measurements is examined for possible errors, and an analytical approach to accommodate such errors is presented
A study of the effect of radical load distributions on calibrated strain gage load equations
For several decades, calibrated strain gages have been used to measure loads on airplanes. The accuracy of the equations used to relate the strain gage measurements to the applied loads has been based primarily on the results of the load calibration. An approach is presented for studying the effect of widely varying load distributions on strain gage load equations. The computational procedure provides a link between the load calibration and the load to be measured in flight. A matrix approach to equation selection is presented, which is based on equation standard error, load distribution, and influence coefficient plots of the strain gage equations, and is applied to a complex, delta-wing structure
Enhancement of localization in one-dimensional random potentials with long-range correlations
We experimentally study the effect of enhancement of localization in weak
one-dimensional random potentials. Our experimental setup is a single mode
waveguide with 100 tuneable scatterers periodically inserted into the
waveguide. By measuring the amplitudes of transmitted and reflected waves in
the spacing between each pair of scatterers, we observe a strong decrease of
the localization length when white-noise scatterers are replaced by a
correlated arrangement of scatterers.Comment: 4 pages, 6 figure
Current and vorticity auto correlation functions in open microwave billiards
Using the equivalence between the quantum-mechanical probability density in a
quantum billiard and the Poynting vector in the corresponding microwave system,
current distributions were studied in a quantum dot like cavity, as well as in
a Robnik billiard with lambda=0.4, and an introduced ferrite cylinder. Spatial
auto correlation functions for currents and vorticity were studied and compared
with predictions from the random-superposition-of-plane-waves hypothesis. In
addition different types of vortex neighbour spacing distributions were
determined and compared with theory.Comment: PTP-LaTeX, 10 pages with 6 figures submitted to Progress of

Selective enhancement of topologically induced interface states in a dielectric resonator chain
The recent realization of topological phases in insulators and
superconductors has advanced the quest for robust quantum technologies. The
prospects to implement the underlying topological features controllably has
given incentive to explore optical platforms for analogous realizations. Here
we realize a topologically induced defect state in a chain of dielectric
microwave resonators and show that the functionality of the system can be
enhanced by supplementing topological protection with non-hermitian symmetries
that do not have an electronic counterpart. We draw on a characteristic
topological feature of the defect state, namely, that it breaks a sublattice
symmetry. This isolates the state from losses that respect parity-time
symmetry, which enhances its visibility relative to all other states both in
the frequency and in the time domain. This mode selection mechanism naturally
carries over to a wide range of topological and parity-time symmetric optical
platforms, including couplers, rectifiers and lasers.Comment: 5 pages, 4 figures, + supplementary information (3 pages, 4 figures
Experimental observation of the mobility edge in a waveguide with correlated disorder
The tight-binding model with correlated disorder introduced by Izrailev and
Krokhin [PRL 82, 4062 (1999)] has been extended to the Kronig-Penney model. The
results of the calculations have been compared with microwave transmission
spectra through a single-mode waveguide with inserted correlated scatterers.
All predicted bands and mobility edges have been found in the experiment, thus
demonstrating that any wanted combination of transparent and non-transparent
frequency intervals can be realized experimentally by introducing appropriate
correlations between scatterers.Comment: RevTex, 4 pages including 4 Postscript figure
