Supersymmetric Reflection Matrices

We briefly review the general structure of integrable particle theories in 1+1 dimensions having N=1 supersymmetry. Examples are specific perturbed superconformal field theories (of Yang-Lee type) and the N=1 supersymmetric sine-Gordon theory. We comment on the modifications that are required when the N=1 supersymmetry algebra contains non-trivial topological charges.Comment: 7 pages, Revtex, 2 figures, talk given at the International Seminar on Supersymmetry and Quantum Field Theory, dedicated to the memory of D.V.Volkov, Kharkov (Ukraine), January 5-7, 199

The 1996 research assessment exercise : the library and information management panel

Reports on the 1996 Research Assessment Exercise (RAE), the fourth such exercise aimed at providing funding councils of UK universities (including former polytechnics) with the necessary data to rate the quality of UK academic research for predetermined units of assessment in order to fund research selectively. Previous RAEs were conducted in 1986, 1989, and 1992 (for a report of the 1992 RAE see JOLIS 26 (3) Sep 94, 141-7 (LISA ref. 9409765)). Reports generally on the work of the Library and Information Management Panel in agreeing criteria specific to their assessment task, particularly the five principal modes of publication: research monographs; articles in scholarly periodicals; refereed conference papers; published research reports; and book chapters. Discusses the methodology used by the Panel, research submissions received and the overall results

Sea Level in the Strait of Gibraltar: Tides

A network of tide gauges with eight observation recording points was in operation in the Strait of Gibraltar during the years 1984 and 1985, which made it possible to draw up detailed charts of the tides showing their refined structure. For the first order, the Strait of Gibraltar represents the nodal line of the stationary wave of the western Mediterranean, which, hypothetically, would end at the Cadiz meridian (6°17.0W). The tide is basically semi-diurnal; on average, 90% of the energy is associated with the second order and, for this, the Strait of Gibraltar tends to represent an antinode of the stationary wave, although the influence of the bottom topography and the rotation is interpreted in phase delays in the sill area (slightly progressive wave) and in increased non-linear constituents of higher orders. The radiational tide S is evaluated in the area studied and it is ascertained that it shows the same characteristics as the tides having strictly gravitational constituents, which implies that it is fundamentally co-oscillating. Order 4 displays characteristics of resonant amplification due to the existence of the free oscillation mode of the western Mediterranean basin the period of which is close to 6 hours. Of order 3 it should be stressed that M3, though small, is perfectly detectable in the area

Femtosecond pulsed laser deposition of nanostructured CdS films

In this work, we report an investigation of the properties of nanostructured deposits obtained from femtosecond pulsed laser deposition of CdS sintered targets. Specifically, we address the effects of laser irradiation wavelength, laser fluence, and substrate temperature (from 25 to 450 °C). The composition of the deposits was characterized using X-ray photoelectron spectroscopy (XPS), their crystallinity by X-ray diffraction (XRD), and the surface morphology was studied by environmental scanning electron microscopy (ESEM) and atomic force microscopy (AFM). It has been found that the smallest nanoparticles, with an average diameter of 25 nm and a narrow size distribution, together with particulates in the range of 80-120 nm, are obtained at the shortest laser wavelength of 266 nm on room-temperature substrates. Deposits do not contain microscopic droplets in any of the explored conditions. © 2010 American Chemical Society.Peer Reviewe

Evolución del perfil comunicacional de los médicos residentes de medicina de familia

ObjetivoConocer cómo evolucionan en los residentes de medicina de familia las habilidades de relación con los pacientes, al comienzo y al final de su tercer año de residencia, cuando atienden a problemas de salud comunes en su especialidad.DiseñoEstudio cuasi-experimental (antesdespués), multicéntrico, de ámbito nacional. Un total de 193 médicos residentes de tercer año de medicina familiar de 8 unidades docentes, que realizaron su residencia entre 1996–1999. Durante este período los residentes realizaron las actividades formativas y asistenciales habituales que marca el Programa Nacional de la Especialidad. Se valoraron 6 escenarios clínicos videograbados con pacientes estandarizados (3 al inicio del tercer año y 3 al finalizar) mediante el cuestionario GATHA-RES. Análisis estadístico descriptivo, bivariado y multivariante.ResultadosSe evaluó un total de 1.024 entrevistas. El tiempo empleado con cada paciente disminuye significativamente al finalizar la residencia; se observa una relación directamente proporcional entre el tiempo de consulta y las puntuaciones obtenidas (p < 0,05). Se detectan mejorías en los aspectos formales y organizativos de la consulta. Por el contrario, las habilidades relacionadas con la exploración de los aspectos personales y contextuales de la dolencia, así como las habilidades negociadoras, empeoran al finalizar el estudio. Las variables que mejor predicen el perfil comunicacional de los residentes fueron: edad (inversamente), duración de la entrevista, formación del tutor en entrevista clínica y unidad docente.ConclusionesLos residentes aprenden a acortar el tiempo de consulta en detrimento de habilidades de comunicación básicas para la realización de una correcta asistencia a los problemas de salud de sus pacientes. Estos resultados sugieren la necesidad de cambios sustanciales en la formación de los médicos residentes de medicina de familia en España.AimsTo study the development of patient relation skills, as used during interviews with patients for health problems that are common within their specialty, in family medicine residents during the third year of their residency program.MethodsQuasi-experimental (before-after), national-level, multicenter study. The participants were 193 third-year residents in family medicine at 8 training units who were trained between 1996 and 1999. During this period all residents participated in the usual training and clinical activities included in the National Plan for this specialty. The GATHA-RES questionnaire was used to evaluated six clinical scenarios in video recordings of encounters with standardized patients (3 at the start of the third year and 3 at the end of the third year). Descriptive, bivariate and multivariate statistical analyses were used.ResultsA total of 1,024 interviews were analyzed. The time spent with each patient decreased significantly at the end of the residency program; the duration of the visit was directly proportional to the score on the GATHA-RES questionnaire (p < 0.05). Improvements were seen in formal and organizational aspects of the interview. In contrast, skills related with the exploration of personal and contextual aspects of the problem, and negotiating skills, were worse at the end of the study. The variables that best predicted residents’ communicational profile were age (inverse relation), duration of the interview, training of the tutor in clinical interviewing, and teaching unit.ConclusionsResidents learn to shorten the duration of the visit to the detriment of communication skills that are basic to appropriate care for their patients’ health problems. These results suggest the need for substantial changes in the training of family medicine residents in Spain

Coastal Upwelling Off The Rias Bajas, Galicia, Northwest Spain I: Hydrographic Studies

Coastal upwelling occurs off the Rias Bajas of Spain between April and October. Superimposed on large-scale upwelling is a mesoscale regime of enhanced upwelling induced by topographic influences. We show that the region surrounding Cape Finisterre has intensified topographically induced upwelling. The rias have a relatively unobstructed connection with the open ocean. Upwelling of high nitrate water on the continental shelf by Ekman transport sets up pressure gradients at the mouth of the rias that induce upwelled water to flow into the rias. Deep water in the rias responds directly to cycles of upwelling and downwelling on the continental shelf

Valence Quark Distribution in A=3 Nuclei

We calculate the quark distribution function for 3He/3H in a relativistic quark model of nuclear structure which adequately reproduces the nucleon approximation, nuclear binding energies, and nuclear sizes for small nuclei. The results show a clear distortion from the quark distribution function for individual nucleons (EMC effect) arising dominantly from a combination of recoil and quark tunneling effects. Antisymmetrization (Pauli) effects are found to be small due to limited spatial overlaps. We compare our predictions with a published parameterization of the nuclear valence quark distributions and find significant agreement.Comment: 18pp., revtex4, 4 fig

Deformed Skyrme Crystals

The Skyrme crystal, a solution of the Skyrme model, is the lowest energy-per-charge configuration of skyrmions seen so far. Our numerical investigations show that, as the period in various space directions is changed, one obtains various other configurations, such as a double square wall, and parallel vortex-like solutions. We also show that there is a sudden "phase transition" between a Skyrme crystal and the charge 4 skyrmion with cubic symmetry as the period is gradually increased in all three space directions.Comment: 13 pages, 6 figures.
