Numerical analysis of four-wave mixing between 2 ps mode-locked laser pulses in a tensile-strained bulk SOA
A numerical model of four-wave mixing between 2-ps pulses in a tensile-strained bulk semiconductor optical amplifier is presented. The model utilizes a modified Schrodinger equation to model the pulse propagation. The Schrodinger equation parameters such as the material gain first and second order dispersion, linewidth enhancement factors and optical loss coefficient are obtained using a previously developed steady-state model. The predicted four-wave mixing pulse characteristics show reasonably good agreement with experimental pulse characteristics obtained using frequency resolved optical gating
Molecular electrostatic potentials by systematic molecular fragmentation
A simple method is presented for estimating the molecular electrostatic potential in and around molecules using systematic molecular fragmentation. This approach estimates the potential directly from the electron density. The accuracy of the method is established for a set of organic molecules and ions. The utility of the approach is demonstrated by estimating the binding energy of a water molecule in an internal cavity in the protein ubiquitin
New Models for Medical Education: Web-Based Conferencing to Support HIV Training in Sub-Saharan Africa
Background: Healthcare workers in Africa managing human immunodeficiency virus (HIV)-infected patients often receive inadequate HIV-specific medical education. The acceptability and feasibility of Web-based distance learning tools to enhance HIV training in Africa have not been extensively evaluated.
Materials and Methods: In this prospective observational study, we assessed the feasibility of Web-conferencing to deliver HIV-specific medical training to clinicians supporting HIV care and treatment across 12 Sub-Saharan African countries over a 10-month period. Webinar attendance, technical quality, and participant satisfaction were measured for each Webinar. Demographic details about participants were recorded.
Results: Attendance increased from 40 participants in Month 1 to over 160 in Month 10. Thirty-six percent of participants were physicians, and 21% were in allied health professions. A mean of 95% of respondents found the content to be relevant. Participants reported that the opportunity to interact with HIV clinicians from other countries and expert teaching from leading scientists were major reasons for attendance. Audio quality was variable across countries and over time. Barriers to attendance included lack of information technology (IT) literacy and Internet connectivity.
Conclusions: This analysis demonstrates that Webinars are feasible and acceptable to support HIV training. Significant impediments to scale up in use of Web-conferencing for HIV education in resource-limited settings include lack of IT hardware and limited IT literacy. Strengthening IT capacity and Internet infrastructure is necessary to support expanded use of Webinars as a tool for continuing HIV education
Efficacy of manual therapy treatments for people with cervicogenic dizziness and pain : Protocol of a randomised controlled trial
BACKGROUND: Cervicogenic dizziness is a disabling condition characterised by postural unsteadiness that is aggravated by cervical spine movements and associated with a painful and/or stiff neck. Two manual therapy treatments (Mulligan’s Sustained Natural Apophyseal Glides (SNAGs) and Maitland’s passive joint mobilisations) are used by physiotherapists to treat this condition but there is little evidence from randomised controlled trials to support their use. The aim of this study is to conduct a randomised controlled trial to compare these two forms of manual therapy (Mulligan glides and Maitland mobilisations) to each other and to a placebo in reducing symptoms of cervicogenic dizziness in the longer term and to conduct an economic evaluation of the interventions. METHODS: Participants with symptoms of dizziness described as imbalance, together with a painful and/or stiff neck will be recruited via media releases, advertisements and mail-outs to medical practitioners in the Hunter region of NSW, Australia. Potential participants will be screened by a physiotherapist and a neurologist to rule out other causes of their dizziness. Once diagnosed with cervciogenic dizziness, 90 participants will be randomly allocated to one of three groups: Maitland mobilisations plus range-of-motion exercises, Mulligan SNAGs plus self-SNAG exercises or placebo. Participants will receive two to six treatments over six weeks. The trial will have unblinded treatment but blinded outcome assessments. Assessments will occur at baseline, post-treatment, six weeks, 12 weeks, six months and 12 months post treatment. The primary outcome will be intensity of dizziness. Other outcome measures will be frequency of dizziness, disability, intensity of cervical pain, cervical range of motion, balance, head repositioning, adverse effects and treatment satisfaction. Economic outcomes will also be collected. DISCUSSION: This paper describes the methods for a randomised controlled trial to evaluate the effectiveness of two manual therapy techniques in the treatment of people with cervicogenic dizziness for which there is limited established evidence-based treatment.

Remarks and Reflections on French Recitative: Ban Inquiry into Performance Practice Based on the Observations of Bénigne de Bacilly, Jean-Léonor de Grimarest, and Jean-Baptiste Dubos
This study concerns the declaimed performance of recitative in early French opera. Because the dramatic use of the voice was crucial to the opera genre, this investigation begins with a survey of historical definitions of declamation. Once the topic has been described, the thesis proceeds to thoroughly study three treatises dealing with sung recitation: Bacilly's Remarques curieuses, Grimarest's Traité de recitatif, and Dubos' Reflexions critiques. Principles from these sources are then applied to representative scenes from the literature. The paper closes with a commentary on the relationship between spoken and sung delivery and on the development of different declamatory styles
Andrew Melville, sacred chronology and world history: the Carmina Danielis 9 and the Antichristus
The accepted view of the ecclesiastical reformer Andrew Melville (1545–1622) as the dynamic leader of the Presbyterian movement in Jacobean Scotland has been severely eroded in recent years, with particular criticism of the actual importance of his contribution to the Kirk and to Scottish higher education. While this reductionism has been necessary, it has resulted in an inversion of the overwhelmingly positive traditional image of Melville, and does not give us a rounded assessment of his life and works. This article attempts to partially redress this balance by looking at a neglected aspect of Melville's Latin writings, which showcase his talents as a humanist intellectual and biblical commentator. It focuses on two long poems that are both commentaries and paraphrases of Daniel and Revelation: the Carmina Danielis and the Antichristus. Through these poems, we see how Melville engaged with two problems exercising reformed theologians across Europe: the dating of key biblical events and the historicised meaning of prophecies within these texts. We also find evidence that Melville read widely among both contemporary and ancient commentators on both these issues

The seroprevalence and factors associated with Ross River virus infection in Western Grey Kangaroos (Macropus fuliginosus) in Western Australia
A serosurvey was undertaken in 15 locations in the midwest to southwest of Western Australia (WA) to investigate the seroprevalence of Ross River virus (RRV) neutralizing antibodies and factors associated with infection in western grey kangaroos (Macropus fuliginosus). The estimated seroprevalence in 2632 kangaroo samples, using a serum neutralization test, was 43.9% (95% CI 42.0, 45.8). Location was significantly associated with seroprevalence (p 0.05). The results of this study indicate that kangaroos in WA are regularly infected with RRV and may be involved in the maintenance and transmission of RRV
