Multilayer ion trap technology for scalable quantum computing and quantum simulation

We present a novel ion trap fabrication method enabling the realization of multilayer ion traps scalable to an in principle arbitrary number of metal-dielectric levels. We benchmark our method by fabricating a multilayer ion trap with integrated three-dimensional microwave circuitry. We demonstrate ion trapping and microwave control of the hyperfine states of a laser cooled 9Be+ ion held at a distance of 35 above the trap surface. This method can be used to implement large-scale ion trap arrays for scalable quantum information processing and quantum simulation

Influence of phosphate dosing on biofilms development on lead in chlorinated drinking water bioreactors

Phosphate dosing is used by water utilities to prevent plumbosolvency in water supply networks. However, there is a lack of knowledge regarding biofilm formation on lead and plastic materials when phosphate concentrations are modified in drinking water systems. In this study, biofilms were grown over lead coupons and PVC tubes in bioreactors supplied with local drinking water treated to provide different phosphate doses (below 1, 1 and 2 mg/L) over a period of 28 days. A range of commercial iron pellets (GEH104 and WARP) were tested aiming to maintain phosphate levels below the average 1 mg/L found in drinking water. Changes in biofilm community structure in response to three different phosphate treatments were characterised by Illumina sequencing of the 16S rRNA gene for bacteria and the ITS2 gene for fungi. Scanning electron microscopy was used to visualise physical differences in biofilm development in two types of materials, lead and PVC. The experimental results from the kinetics of phosphate absorption showed that the GEH104 pellets were the best option to, in the long term, reduce phosphate levels while preventing undesirable turbidity increases in drinking water. Phosphate-enrichment promoted a reduction of bacterial diversity but increased that of fungi in biofilms. Overall, higher phosphate levels selected for microorganisms with enhanced capabilities related to phosphorus metabolism and heavy metal resistance. This research brings new insights regarding the influence of different phosphate concentrations on mixed-species biofilms formation and drinking water quality, which are relevant to inform best management practices in drinking water treatment

Análisis de la Motivación, la Satisfacción y el Esfuerzo en la Implantación de un Grado Bilingüe

La internacionalización de las enseñanzas a través de la implantación de titulaciones bilingües presenta importantes retos para el alumnado, el profesorado y la institución. La identificación temprana de barreras y problemas es fundamental para lograr con éxito su implantación. Con este objetivo en mente, este trabajo presenta los resultados obtenidos de la evaluación de la implantación de un título bilingüe en un grado de Ingeniería Informática. En concreto, se han contemplado tres ejes fundamentales dentro de esta evaluación: (1) la motivación del alumnado para no elegir enseñanzas en inglés, (2) la satisfacción del alumnado con el desarrollo de las asignaturas en inglés, y (3) el esfuerzo del profesorado en la docencia en inglés. A partir de estos datos se realiza un análisis de la docencia en castellano y la docencia en inglés para el mismo conjunto de asignaturas. El objetivo último del estudio es proponer acciones para la mejora continua, así como extraer conclusiones sobre el funcionamiento del título que puedan servir como referencia para la puesta en marcha o mejora de otras iniciativas de implantación de títulos bilingües.Higher education internationalization by means of bilingual degrees presents great challenges for students, teaching staff and institutions. Early identification of burdens and issues is of utmost importance to offer such studies successfully. Within that goal, this work presents results obtained from the evaluation of a new bilingual degree (English) in Computer Science. Concretely, three main dimensions has been evaluated: (1) students’ motivation to learn in English; (2) students’ satisfaction with English teaching; and (3) perceived staff effort to teach in English. Based on the resulting data we perform an analysis about teaching in English and in Spanish the same subject set. The final goal of this study is to propose concrete actions for continuous enhancement and to derive conclusions about degree development, so that they may be useful for other initiatives of bilingual educational programs

"A little theatrical but mostly athletic": The mutable erotics of Miranda July's The First Bad Man

By attending to the inherent flux of sexual fantasy, Miranda July’s first novel The First Bad Man reveals a mobile and mutable erotics capable of generating an enlarged range of self-identification and relational intimacy, far from any essentialist assumptions of stable or coherent sexual identity. July focuses specifically upon role-play as the means to unpack the normative categories of hetero/homosexuality, masculinity and femininity, celebrating rather than pathologising qualities like superficiality and inconsistency. The novel touches upon many polarising issues (for example, sexual violence, sadomasochism and assisted reproductive technology), deftly avoiding the conventional language which colours perception. Both erotic and humorous, The First Bad Man helps to redefine the often highly charged discourse around sex and sexuality

Complicaciones de la colocación de malla sintética vaginal para la incontinencia urinaria de esfuerzo

ResumenAntecedentesLas mallas para la incontinencia urinaria (IU) se han utilizado a pesar de la falta de evidencia de nivel i en la literatura para evaluar su seguridad y eficacia a largo plazo. Las complicaciones relacionadas con la malla provocaron una advertencia emitida por la FDA en 2008 y dejaron de ser consideradas eventos raros. Las complicaciones más comunes son la retención aguda de orina, sangrado, recurrencia o persistencia de la IU, erosión de uretra e infección de la malla.ObjetivoConocer cuáles son las complicaciones derivadas del tratamiento quirúrgico de la IU femenina con la colocación de mallas suburetrales.Material y métodoSe analizaron los pacientes con diagnóstico de IU operadas con cirugía antiincontinencia y colocación de malla vaginal del año 2007 al 2014. Se analizó las complicaciones derivadas de la colocación de malla y la recuperación de continencia.ResultadosA 58 pacientes se les colocó sling (cabestrillo) con malla sintética; edad promedio de 56 años. El 51% de las pacientes tenían IU de esfuerzo y el 49% IU mixta. Las complicaciones tempranas fueron: 4 pacientes con retención aguda de orina. Las complicaciones tardías: dolor uretral o vaginal (12.2%), dispareunia (20%) y extrusión de malla (10%) manejado con retiro de la misma, 2 de ellas requiriendo 2 procedimientos quirúrgicos. El 12% presentaron urgencia de novo, el 90.2% evolucionaron sin incontinencia, el 9.7% con IU postoperatoria y 2 pacientes sin mejoría.DiscusiónNuestra serie, aunque pequeña, muestra una baja tasa de complicaciones a largo plazo relacionadas con la malla en comparación con la mayoría de las series que muestran una tasa de reoperación de hasta>70% y con múltiples casos de retiro de malla, por lo que en nuestra experiencia los slings suburetrales continúan siendo una opción adecuada en el manejo de la IU.ConclusionesLos slings suburetrales son una opción segura y efectiva en el manejo de la IU.AbstractBackgroundSurgical mesh has been used for treating urinary incontinence (UI) despite the lack of level i evidence in the literature evaluating its long-term safety and efficacy. Mesh-related complications were responsible for a warning issued by the FDA in 2008 and they stopped being considered rare events. The most common complications are acute urinary retention, bleeding, recurrence or persistence of UI, erosion of the urethra, and mesh infection.AimsTo determine the complications derived from surgical UI treatment with the placement of suburethral mesh in women.Material and methodPatients diagnosed with UI that underwent anti-incontinence surgery with the placement of vaginal mesh within the time frame of 2007 and 2014 were analyzed. Mesh placement complications and the recovery of continence were evaluated.ResultsA synthetic mesh sling was placed in 58 patients with a mean age of 56 years. A total of 51% of the patients had stress urinary incontinence and 49% had mixed urinary incontinence. Early complications were: 4 patients with acute urine retention. Late complications were: urethral or vaginal pain (12.2%), dyspareunia (20%), and mesh extrusion (10%) that was managed through mesh removal; 2 of those patients required surgical procedures. Twelve percent of the patients presented with de novo urgency, 90.2% progressed with no incontinence, 9.7% presented with postoperative UI, and 2 patients had no improvement.DiscussionAlthough small, our case series showed a low long-term complication rate with the use of surgical mesh, compared with the majority of case series that demonstrate a re-operation rate>70%, as well as numerous cases of mesh removal. Thus, it is our experience that suburethral slings continue to be an adequate UI management option.ConclusionsSuburethral slings are a safe and effective option in UI management
