Generating controllable atom-light entanglement with a Raman atom laser system

We introduce a scheme for creating continuous variable entanglement between an atomic beam and an optical field, by using squeezed light to outcouple atoms from a BEC via a Raman transition. We model the full multimode dynamics of the atom laser beam and the squeezed optical field, and show that with appropriate two-photon detuning and two-photon Rabi frequency, the transmitted light is entangled in amplitude and phase with the outcoupled atom laser beam. The degree of entanglement is controllable via changes in the two-photon Rabi frequency of the outcoupling process.Comment: 4 pages, 4 figure

Modification of the Ingram bicycle seat stool for the treatment of vaginal agenesis and stenosis

The use of nonsurgical techniques for the creation of a neovagina for vaginal agenesis and stenosis has been successful for many patients and is currently recommended as first‐line therapy. The Ingram bicycle seat stool technique, a nonsurgical approach, has largely replaced the surgical McIndoe technique as the method of choice for vaginal dilation. It provides an easy and comfortable way for patients to engage in dilation. However, the Ingram bicycle seat stool is not height adjustable. We have created a bicycle seat stool that is height adjustable and will likely provide patients with an improved, more comfortable, and individualized method of dilation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135330/1/ijgo301.pd

Achieving peak brightness in an atom laser

In this paper we present experimental results and theory on the first continuous (long pulse) Raman atom laser. The brightness that can be achieved with this system is three orders of magnitude greater than has been previously demonstrated in any other continuously outcoupled atom laser. In addition, the energy linewidth of a continuous atom laser can be made arbitrarily narrow compared to the mean field energy of a trapped condensate. We analyze the flux and brightness of the atom laser with an analytic model that shows excellent agreement with experiment with no adjustable parameters.Comment: 4 pages, 4 black and white figures, submitted to Physical Revie

People who inject drugs experiences of skin and soft tissue infections and harm reduction: A qualitative study.

Background: Bacterial skin and soft tissue infections (SSTI) among people who inject drugs (PWID) are considered a public health concern. There is a lack of qualitative research examining the lived experience of PWID who have had SSTI. This paper explores PWID views and experiences of their SSTI, their perceptions on the causes of their SSTI and their harm reduction (HR) behaviours. The implications for HR service delivery and practice will be discussed. Methods: Between October 2015-January 2016, 22 in-depth interviews were conducted with PWID who had experienced a SSTI within the past year. Interviewees were recruited from an injecting equipment provision service and a drug treatment service in Glasgow and Edinburgh respectively. The interview transcripts were transcribed verbatim and underwent thematic analysis. Results: We found that the experience of SSTI can cause strong negative feelings, including panic and stigma and that there was limited knowledge of SSTI prior to first hand experience. The awareness of the unacceptable social and physical consequences of SSTI fostered a sense of personal responsibility and agency which led to the introduction or improved HR uptake. However, when PWID were struggling to inject or when their physical and political environments were compromised there was an increased risk for SSTI and reduced effectiveness of HR. Conclusion: Compared to HCV and HIV, SSTI as an injecting related harm has received less policy attention. Policy makers need to address SSTI HR within enabling environments, such as ‘safer environment interventions’. It is recommended that peer based support, improved NSP provision and medically supervised injecting facilities are needed to deliver SSTI HR

Lamb and Wool Production as Influenced by Breed of Ewem Age and Management System (Progress Report)

The number of lambs marketed per ewe exposed has the greatest effect, of many factors studied including individual lamb weight, on the total weight of lamb marketed per ewe per year. Various approaches have been attempted to increase the number of lambs born per ewe lambing. Management techniques such as flushing, time of breeding and hormone therapy have all yielded success within moderate limits. The most successful approach at increasing lambing rate on a permanent basis has been by selection of appropriate breeds and/or their crosses. Although this has resulted in increased ovulations and birth rates, little information is available on total lifetime production in South Dakota. The purpose of this study was to evaluate a crossbred ewe (FDT) developed for potential high productivity under farm or range conditions found in South Dakota

Erratum : Squeezing and entanglement delay using slow light

An inconsistency was found in the equations used to calculate the variance of the quadrature fluctuations of a field propagating through a medium demonstrating electromagnetically induced transparency (EIT). The decoherence term used in our original paper introduces inconsistency under weak probe approximation. In this erratum we give the Bloch equations with the correct dephasing terms. The conclusions of the original paper remain the same. Both entanglement and squeezing can be delayed and preserved using EIT without adding noise when the decoherence rate is small.Comment: 1 page, no figur

Inequality, exclusion and infant mortality: listening to bereaved mothers

yesThis chapter will examine issues of social justice by focussing on social exclusion and infant mortality. Infant mortality is defined as the death of a live born child before its first birthday. Social exclusion and infant mortality are both important areas of policy debate in the UK and globally (1).We will examine how far they are linked and will focus on ethnic minority populations with higher than average rates of infant mortality. The chapter continues by considering a small group of women who have experienced the death of an infant and who have come together in a group called HOPE. We ask how their experience might inform our understanding of the needs of women at the time of childbirth and in the weeks immediately following it. Their experiences illuminate how feelings of exclusion, and injustice, can be manifest in and through the structures and processes of engaging with health care professionals. The potential to promote social justice and enhance inclusion via listening to the voices of those who have had this experience of loss is considere
