Lateral imaging of the superconducting vortex lattice using Doppler-modulated scanning tunneling microscopy

By spatially mapping the Doppler effect of an in-plane magnetic field on the quasiparticle tunneling spectrum, we have laterally imaged the vortex lattice in superconducting 2H-NbSe2. Cryomagnetic scanning tunneling spectroscopy was performed at 300 mK on the ab-surface oriented parallel to the field H. Conductance images at zero bias show stripe patterns running along H, with the stripe separation varying as H^-0.5. Regions of higher zero-bias conductance show lower gap-edge conductance, consistent with spectral redistribution by spatially-modulated superfluid momentum. Our results are interpreted in terms of the interaction between vortical and screening currents, and demonstrate a general method for probing subsurface vortices.Comment: 3 pages, 3 figures, to appear in Applied Physics Letter

Consumo de antidepresivos y ansiolíticos en Argentina en 1998

Fundamentos: Realizar una estadística sobre el consumo de drogas antidepresivas y ansiolíticas durante el año 1998fin de obtener conclusiones que nos permitan aportar datos para racionalizar el uso.Método: Se obtuvieron los datos de distribución de las dos más grandes droguerías proveedoras de medicamentosde la Región del Nordeste Argentino y de las farmacias elaboradoras de prescripciones magistrales con éstos fármacos.Resultados: Los datos obtenidos fueron los siguientes: cantidad de unidades distribuidas por las droguerías expendedoras:18.080 de antidepresivos y 177.205 de ansiolíticos y de las oficinas de farmacia magistrales de la zona seobtuvieron la cantidad de recetas preparadas con estas drogas: 4440.Conclusiones: Se evidencia un predominio de la medicación elaborada por la industria farmacéutica sobre lospreparados magistrales realizados por las oficinas de farmacia, aunque éstos últimos son utilizados de manera másracional

Preface

In August 2014 a conference on “Model reduction across disciplines” was held in Leicester, UK. As a scientific field, model reduction is an important part of mathematical modelling and data analysis with very wide areas of applications. The main scientific goal of the conference was to facilitate interdisciplinary discussion of model reduction and coarse-graining methodologies in order to reveal their general mathematical nature. This time, however, the conference had an additional personal and more profound mission – it was dedicated to the 60th birthday of Professor Alexander Gorban (albeit with some delay) whose fantastic achievements in applying model reduction techniques to a wide range of disciplines, from physical kinetics and fluid dynamics, to biochemical kinetics and data analysis, are well known in the scientific community

First report of Streptococcus parauberis in a cultured freshwater ornamental fish, the ram cichlid Mikrogeophagus ramirezi (Myers & Harry, 1948)

First paragraph: Since the first report of an outbreak of a streptococcal infection in rainbow trout (Oncorhynchus mykiss) in Japan in 1958 (Hoshina, Sano, & Morimoto,1958), streptococcosis has been responsible for significant mortalities resulting in considerable losses to the aquaculture industry (Noga,2010; Salati,2006). Numerous species from the family Streptococcaceae have been identified as aetiological agents of streptococcosis in fish (Noga,2010; Salati,2006; Toranzo, Magariños, & Romalde,2005), susceptibility to which was documented in both food (Inglis, Roberts, & Bromage,1993) and ornamental fish species (Russo, Mitchell, & Yanong,2006).Streptococcus parauberisis a coccoid, non-motile, alpha-haemolytic Gram-positive bacterium belonging to theStreptococcaceafamily (Nho etal.,2011) and has been reported as the aetiological agent of streptococcosis in a few fish species, including turbot (Scophthalmus maximus), olive flounder (Paralichthys olivaceus), sea bass (Sebastes ventricosus) and striped bass (Morone saxatilis) (Baeck, Kim, Gomez, & Park,2006; Domeénech etal.,1996; Haines etal.,2013; Mata etal.,2004; Oguro etal.,2014; Park etal.,2009).Streptococcus parauberishas been previously identified as the aetiological agent of bovine mastitis (Bradley,2002). It was formerly known asStreptococcustype II until comparative analysis of the sequence data ofStreptococcus uberistypes I and II showed that both were phylogenetically distinct, and the new speciesS.parauberiswas proposed (Williams and Collins1990)

Remote detection of trailing vortices, task 3, modification 3

The operation of a frequency tracker for use with the laser Doppler velocimeter (LDV) is reported. Topics discussed include: laser beam profile, lens matching, and LDV resolution data. It is concluded that the LDV provides good ground wind signals. The loss in sensitivity of the cavity system at high frequencies is partly compensated by an increase in the scattering cross section of the atmosphere due to dust
