A Low-Cost FPGA-Based Test and Diagnosis Architecture for SRAMs

The continues improvement of manufacturing technologies allows the realization of integrated circuits containing an ever increasing number of transistors. A major part of these devices is devoted to realize SRAM blocks. Test and diagnosis of SRAM circuits are therefore an important challenge for improving quality of next generation integrated circuits. This paper proposes a flexible platform for testing and diagnosis of SRAM circuits. The architecture is based on the use of a low cost FPGA based board allowing high diagnosability while keeping costs at a very low leve

Multicolour photometry for exoplanet candidate validation

Context. The TESS and PLATO missions are expected to find vast numbers of new transiting planet candidates. However, only a fraction of these candidates will be legitimate planets, and the candidate validation will require a significant amount of follow-up resources. Radial velocity follow-up can be carried out only for the most promising candidates around bright, slowly rotating, stars. Thus, before devoting RV resources to candidates, they need to be vetted using cheaper methods, and, in the cases for which an RV confirmation is not feasible, the candidate's true nature needs to be determined based on these alternative methods alone. Aims. We study the applicability of multicolour transit photometry in the validation of transiting planet candidates when the candidate signal arises from a real astrophysical source. We seek to answer how securely can we estimate the true uncontaminated star-planet radius ratio when the light curve may contain contamination from unresolved light sources inside the photometry aperture when combining multicolour transit observations with a physics-based contamination model. Methods. The study is based on simulations and ground-based transit observations. The analyses are carried out with a contamination model integrated into the PyTransit v2 transit modelling package, and the observations are carried out with the MuSCAT2 multicolour imager installed in the 1.5 m TCS in the Teide Observatory. Results. We show that multicolour transit photometry can be used to estimate the amount of flux contamination and the true radius ratio. Combining the true radius ratio with an estimate for the stellar radius yields the true absolute radius of the transiting object, which is a valuable quantity in statistical candidate validation, and enough in itself to validate a candidate whose radius falls below the theoretical lower limit for a brown dwarf.Comment: Accepted to A&

Surface and Temporal Biosignatures

Recent discoveries of potentially habitable exoplanets have ignited the prospect of spectroscopic investigations of exoplanet surfaces and atmospheres for signs of life. This chapter provides an overview of potential surface and temporal exoplanet biosignatures, reviewing Earth analogues and proposed applications based on observations and models. The vegetation red-edge (VRE) remains the most well-studied surface biosignature. Extensions of the VRE, spectral "edges" produced in part by photosynthetic or nonphotosynthetic pigments, may likewise present potential evidence of life. Polarization signatures have the capacity to discriminate between biotic and abiotic "edge" features in the face of false positives from band-gap generating material. Temporal biosignatures -- modulations in measurable quantities such as gas abundances (e.g., CO2), surface features, or emission of light (e.g., fluorescence, bioluminescence) that can be directly linked to the actions of a biosphere -- are in general less well studied than surface or gaseous biosignatures. However, remote observations of Earth's biosphere nonetheless provide proofs of concept for these techniques and are reviewed here. Surface and temporal biosignatures provide complementary information to gaseous biosignatures, and while likely more challenging to observe, would contribute information inaccessible from study of the time-averaged atmospheric composition alone.Comment: 26 pages, 9 figures, review to appear in Handbook of Exoplanets.

Perfil de pacientes hematológicos atendidos en un servicio de urgencias hospitalario

Poster [PC-355] Introducción: Durante los últimos años existe un aumento progresivo en la demanda de asistencia en los servicios de urgencias hospitalarios (SUH), tanto generales como pediátricos. Los pacientes hematológicos presentan numerosos episodios clínicos que precisan valoración clínica urgente y dada la facilidad de acceso a los SUH emplean este medio. Métodos: Estudio descriptivo observacional de las urgencias en pacientes con patología hematológica atendidas en el Servicio de Urgencias del Hospital Universitario Miguel Servet de Zaragoza (Hospital de tercer nivel). Periodo de estudio (Enero 2017-Diciembre 2017). Criterios de inclusión: Paciente: s con diagnóstico hematológico según la clasificación CIE-9 en el informe de alta de urgencias. Grupo de pacientes adultos (> 14 años): atendidos en el Hospital General, y grupo de pacientes pediátricos (< 14 años): atendidos en el Hospital Infantil. Variables analizadas: edad, sexo, grupo de patología y nivel de triaje. Datos recogidos a través del registro derivado de la Base de Datos generada por el aplicativo informático “Puesto Clínico Hospitalario de Urgencias”, que da soporte a la actividad asistencial de los servicios de urgencias hospitalarios de Aragón. Se obtuvo autorización correspondiente del centro y del SUH para el acceso a los datos informáticos. Resultados: Muestra total de 2193 pacientes: 1928 en el grupo de adultos y 265 en el grupo pediátrico. En el grupo de adultos la edad media de consulta en SUH fue de 71, 4 años (DE: 18.10), siendo el subgrupo de 81-90 años el que más frecuentemente acude (31.74%). En la población infantil la edad media de consulta fue de 6, 39 años (DE: 4.54), siendo entre los 0-2 años la edad que más frecuenta Urgencias (19.62%). Respecto a la distribución según sexo, el 55% de las consultas son realizadas por mujeres y el 45% por hombres. Sin embargo, en la población infantil el 52% de las consultas son realizadas por niños y el 48% por niñas. En el análisis según grupo de enfermedad: el grupo pediátrico consulta más frecuentemente por enfermedades de hemostasia (47.17%), mientras que los adultos consultan más por enfermedades de serie roja (61.28%). En ambos grupos, las consultas realizadas en Urgencias son de gran complejidad con una prioridad elevada de asistencia. El 93% de la patología en adultos y el 71% de la patología infantil hematológica es triada con niveles I-III de urgencia y tiempos asistenciales reducidos. Conclusiones: El comportamiento de las enfermedades hematológicas varía en función de la edad, el sexo y el tipo de enfermedad. La patología hematológica tiene un gran impacto dentro de los servicios de urgencias hospitalarios, dado que estos pacientes presentan un perfil complejo que requerirá diagnóstico y tratamiento rápido por la gravedad del tipo de complicaciones que asocian. En consonancia con la población envejecida, los pacientes que más demandan la atención en Urgencias y de forma repetida, son adultos muy mayores (81-90 años) pudiéndose plantear circuitos de asistencia urgente diferentes para estos pacientes

HD 219666 b: a hot-Neptune from TESS Sector 1

We report on the confirmation and mass determination of a transiting planet orbiting the old and inactive G7 dwarf star HD219666 (M-star = 0.92 +/- 0.03 M-circle dot, R-star = 1.03 +/- 0.03 R-circle dot, tau(star) = 10 +/- 2 Gyr). With a mass of M-b = 16.6 +/- 1.3 M-circle plus, a radius of R-b = 4.71 +/- 0.17 R-circle plus, and an orbital period of P-orb similar or equal to 6 days, HD219666 b is a new member of a rare class of exoplanets: the hot-Neptunes. The Transiting Exoplanet Survey Satellite (TESS) observed HD219666 (also known as TOI-118) in its Sector 1 and the light curve shows four transit-like events, equally spaced in time. We confirmed the planetary nature of the candidate by gathering precise radial-velocity measurements with the High Accuracy Radial velocity Planet Searcher (HARPS) at ESO 3.6 m. We used the co-added HARPS spectrum to derive the host star fundamental parameters (T-eff = 5527 +/- 65 K, log g(star) = 4.40 +/- 0.11 (cgs), [Fe/H] = 0.04 +/- 0.04 dex, log R-HK\u27 = -5.07 +/- 0.03), as well as the abundances of many volatile and refractory elements. The host star brightness (V = 9.9) makes it suitable for further characterisation by means of in-transit spectroscopy. The determination of the planet orbital obliquity, along with the atmospheric metal-to-hydrogen content and thermal structure could provide us with important clues on the formation mechanisms of this class of objects

Threshold voltage mismatch (Delta;VT) fault modeling

A reduced intrinsic threshold voltage (VT) in addition to its variability has a direct impact on circuit design. Worst-case design styles assume that all transistors use the same worst-case VT whose average and standard deviation come from inter-die statistical variations. However, intra-die differences, such as random local VT variations are not considered and may pose a serious problem for designs based on low-voltage low-power premises, e.g. clock skews, excessive leakage current, out of spec critical-path delays, etc. This paper formulates a fault model based on threshold voltage mismatch and analyzes its impact on circuit design. Simulation and experimental results support the fault model
