BowScribe: Supporting the violinist's performance model
Musicians often learn about their vision of a
piece through practicing it and listening to recordings. However,
this does not always free the player to develop his or her own
interpretation of the piece, especially when technique is lacking. We
have developed software, the BowScribe markup language, that supports
a violinist in creating a ``performance model'' of a piece currently
beyond his or her playing skills, by allowing the player fine control
over tempo, volume, and articulation, including playing of chords, at
a level of expressiveness and flexibility that is significantly beyond
the MIDI playback modes of popular music notation software. BowScribe
has been used by the first author (who was trained as a prfessional
violinist) to create a model of the entire Bach Chaconne (edited by
Glamian), a long and demanding piece of music for solo violin that has
many phrases that span groups of chords as well as melodic passages.
The markup language specified chords to be rolled in two classic ways,
as well as a wide variety of other strokes, including greater volume
for individual notes in long slurs and small but essential variations
in tempo
The Segal--Bargmann transform for odd-dimensional hyperbolic spaces
We develop isometry and inversion formulas for the Segal--Bargmann transform
on odd-dimensional hyperbolic spaces that are as parallel as possible to the
dual case of odd-dimensional spheres.Comment: To appear in Mathematic

The relationship between visual memory and rider expertise in a show-jumping context
Individuals develop visual skills while participating in sport. The aim of this study was to assess the effect of reported riding expertise on the recall of visual information relating to show-jumps. We identified a relevant (F1) and irrelevant (F2) point of focus in 22 photographs of show-jumps. Participants were students (n = 40) with varying levels of horse riding ability. The task, having viewed each photograph for four seconds, was to identify F1s or F2s from four alternatives viewed for ten seconds. F1s were recalled significantly more than F2s (P<0.001). Riding expertise did not affect overall recall but only intermediate/advanced riders recalled F1s significantly better than F2s (P<0.05 and P<0.001 respectively). Recall of F1s but not of F2s was significantly correlated with riding expertise (P<0.05). Training riders in visual attention techniques might improve ridden performance and could reduce the number of accidents associated with lack of experience and/or rider error
Roles, service knowledge and priorities in the provision of palliative care: a postal survey of London GPs
Objectives: To explore general practitioners' (GPs) current involvement in and attitudes towards the provision of palliative care in primary care. Methods: Postal survey of 356 London-based GPs, assessing attitudes towards palliative care provision, district nursing and specialist palliative care services, and priorities for future service development. Results: Currently, 65% of GPs were providing palliative care to patients on their list; 72% agreed or strongly agreed palliative care was a central part of their role; and 27% wanted to hand care over to specialists. Most GPs (66%) disagreed with the statement that 'palliative care is mainly district nursing (DN) work'. Many were unaware of out-of-hours DN and specialist palliative care services. Multi-variable analysis found four GP characteristics - larger practice size, more years experience as a GP, receipt of palliative care education, and current provision of palliative care - were associated with agreement that palliative care was central to a GP's role. Conclusion: A minority of NHS GPs in London would rather have no involvement in palliative care in primary care. Knowledge of current services for palliative care is generally poor among GPs. These findings highlight potential gaps in services, particularly in small practices. Specialists will need to consider these factors in working with GPs to develop primary palliative care and to enable greater access to specialist palliative care
