An Alpha Particle Model for Carbon-12

We introduce a new model for the Carbon-12 nucleus and compute its lowest energy levels. Our model is inspired by previous work on the rigid body approximation in the $B=12$ sector of the Skyrme model. We go beyond this approximation and treat the nucleus as a deformable body, finding several new states. A restricted set of deformations is considered, leading to a configuration space $\mathcal{C}$ which has a graph-like structure. We use ideas from quantum graph theory in order to make sense of quantum mechanics on $\mathcal{C}$ even though it is not a manifold. This is a new approach to Skyrmion quantisation and the method presented in this paper could be applied to a variety of other problems.Comment: New figures added.

Quantum graph model for rovibrational states of protonated methane

We extend the quantum graph model for the protonated methane (CH5+) molecular ion, allowing for orientational degrees of freedom. This enables us to compute J>0 rovibrational states, and we present our results for J=0,1,2,3

Coriolis terms in Skyrmion Quantization

We consider the problem of quantizing a Skyrmion which is allowed to vibrate, rotate and isorotate. Previous approaches have neglected the interactions between vibrations and zero modes (analogous to so-called Coriolis terms in the molecular physics literature). A new formalism incorporating these interactions is introduced, inspired by a principal bundle approach to deformable-body dynamics. We quantize the B=4 and B=7 Skyrmions and compare the results to observed nuclear properties of Helium-4 and the Lithium-7/Beryllium-7 isospin doublet

Exploring aspects of physiotherapy care valued by breast cancer patients

OBJECTIVE: To explore the reported value of physiotherapy care received by patients who had accessed a Specialist Breast Care Physiotherapy Service. DESIGN: Exploratory qualitative study using in-depth interviews to explore aspects of physiotherapy care valued by breast cancer patients. Thematic network analysis was used to interpret the data and bring together the different experiences of the participants and identify common themes. SETTING: Physiotherapy Department at a NHS Foundation Trust Teaching Hospital. PARTICIPANTS: Nineteen participants were recruited and three were selected to take part in the in-depth interviews. All participants had received physiotherapy care from a Specialist Breast Care Physiotherapy Service and had been discharged within the last six months. RESULTS: Participants valued a patient-centred holistic approach to care and access to a Specialist Service with an experienced clinician. In particular the importance of the therapeutic alliance and the value of psychological, emotional and educational support emerged, with the participants feeling empowered in their recovery. CONCLUSION AND CLINICAL IMPLICATIONS: Participants reported an overall positive experience of their physiotherapy care. This study supports the need for service providers to evaluate their current physiotherapy provision and subsequently develop Specialised Services to meet the physiotherapy needs of breast cancer patients throughout all stages of their treatment pathway from the delivery of pre-operative care through to post-treatment follow-up

Development and application of the GIM code for the Cyber 203 computer

The GIM computer code for fluid dynamics research was developed. Enhancement of the computer code, implicit algorithm development, turbulence model implementation, chemistry model development, interactive input module coding and wing/body flowfield computation are described. The GIM quasi-parabolic code development was completed, and the code used to compute a number of example cases. Turbulence models, algebraic and differential equations, were added to the basic viscous code. An equilibrium reacting chemistry model and implicit finite difference scheme were also added. Development was completed on the interactive module for generating the input data for GIM. Solutions for inviscid hypersonic flow over a wing/body configuration are also presented
