Tool for fast mismatch analysis of analog circuits

A tool is presented that evaluates statistical deviations in performance characteristics of analog circuits, starting from statistical deviations in the technological parameters of MOS transistors. Performance is demonstrated via the analysis of a Miller OTA in two different configurations and a linearized CMOS transconductor. The CPU time is reduced by a factor of 25 to 90 with respect to conventional Monte Carlo simulation, while maintaining similar accuracy in the computations

An advanced symbolic analyzer for the automatic generation of analog circuit design equations

A tool for symbolic analysis of analog integrated circuits is presented featuring accurate simplification, pole/zero extraction, and tools for parametric AC circuit characterization. The program, called ASAP, uses signal flowgraph methods and has been written in C for portability. In its current version, ASAP is able to deal with the complexity levels arising in typical analog building blocks when described by device-level models. The ASAP inputs and outputs, the architecture, and the graphical interface are discussed

Benchmarking Particle Filter Algorithms for Efficient Velodyne-Based Vehicle Localization

Keeping a vehicle well-localized within a prebuilt-map is at the core of any autonomous vehicle navigation system. In this work, we show that both standard SIR sampling and rejection-based optimal sampling are suitable for efficient (10 to 20 ms) real-time pose tracking without feature detection that is using raw point clouds from a 3D LiDAR. Motivated by the large amount of information captured by these sensors, we perform a systematic statistical analysis of how many points are actually required to reach an optimal ratio between efficiency and positioning accuracy. Furthermore, initialization from adverse conditions, e.g., poor GPS signal in urban canyons, we also identify the optimal particle filter settings required to ensure convergence. Our findings include that a decimation factor between 100 and 200 on incoming point clouds provides a large savings in computational cost with a negligible loss in localization accuracy for a VLP-16 scanner. Furthermore, an initial density of ∼2 particles/m 2 is required to achieve 100% convergence success for large-scale (∼100,000 m 2 ), outdoor global localization without any additional hint from GPS or magnetic field sensors. All implementations have been released as open-source software

System dynamics modelling in systems biology and applications in pharmacology

El modelado matemático de sistemas biológicos complejos es uno de los temas clave en la Biología de Sistemas y varios métodos computacionales basados ​​en la simulación computarizada han sido aplicados hasta ahora para determinar el comportamiento de los sistemas no lineales. La Dinamica de Sistemas es una metodología de modelado intuitivo basada en el razonamiento cualitativo por el cual un modelo conceptual se puede describir como un conjunto de relaciones de causa y efecto entre las variables de un sistema. A partir de esta estructura, es posible obtener un conjunto de ecuaciones dinámicas que describan cuantitativamente el comportamiento del sistema. Centrándose en los sistemas farmacológicos, el modelado compartimental a menudo se utiliza para resolver un amplio espectro de problemas relacionados con la distribución de materiales en los sistemas vivos en la investigación, el diagnóstico y la terapia en todo el cuerpo, los órganos y los niveles celulares. En este artículo presentamos la metodología de modelado de Dinámica del Sistema y su aplicación al modelado de un modelo compartimental farmacocinético-farmacodinámico del efecto de profundidad anestésica en pacientes sometidos a intervenciones quirúrgicas, derivando un modelo de simulación en el entorno de simulación orientada a objetos OpenModelica. La Dinamica de Sistemas se puede ver como una herramienta educativa poderosa y fácil de usar y en la enseñanza de Biología de Sistemas.Universidad de Málaga.

Satisfaction with the Care Received and the Childbirth and Puerperium Experience in Christian and Muslim Pregnant Women

Over the last three decades, there has been an increase in the population as a result of the migratory flow due to the arrival of migrants to Spain, including young women of childbearing age and with reproductive capacity. This phenomenon has made childbirth assistance an extremely important priority in recent years. The aim of this study was to assess the satisfaction and experience during childbirth and the postpartum period in pregnant women according to their religion after assistance in a tertiary hospital. A descriptive cross-sectional study was conducted on a sample of 242 women using the validated Spanish version of the Mackey Childbirth Satisfaction Rating Scale (MCSRS) to measure satisfaction with the childbirth experience during the months of January to April 2021. Statistically significant differences were found in the domains of birth satisfaction (p < 0.01), satisfaction with the obstetrician (p < 0.01), and perception of pain during labour (p < 0.01). The Christian group of women scored higher in these three domains as compared to the Muslim group. The rate of breastfeeding at birth was 5.26 times higher among the Muslim group compared to the Christian group (p = 0.02). The experience of childbirth and the puerperium significantly influenced the levels of satisfaction of pregnant women with the process of childbirth in a different way according to the religious culture of the patient

The lexical constructional model meets syntax: guidelines of the formalized lexical-constructional model (FL_CxG )

[EN] This paper offers the basic guidelines of a formalized version of the Lexical Constructional Model (LCM; Ruiz de Mendoza & Mairal Usón, 2008, 2011; Ruiz de Mendoza & Galera, 2014), the Formalized Lexical-Constructional Grammar (FL_CxG), which will pave the way for future computational developments, such as parsers or lexical databases. The FL_CxG deploys (i) the typologically oriented syntactic apparatus of Role and Reference Grammar (Van Valin, 2005; Van Valin & LaPolla, 1997), (ii) the catalogue of constructional units arranged in a 4-layer typology, as proposed by the LCM, and (iii) some insights for semantic representations from the Generative Lexicon Theory (Pustejovsky, 1995; Pustejovsky & Batiukova, 2019), and Minimal English (Goddard, 2018). All the components of the FL_CxG (lexical units and construct(ion)s) are formally encoded as Typed Feature Structures in the format of Attribute Value Matrixes. These units are to be understood as constraints operating in the unification processes which underlie the generation/decoding of a given fragment of language.[ES] Este trabajo ofrece las directrices básicas de una versión formalizada del Modelo Léxico Construccional (MCL; Ruiz de Mendoza & Mairal Usón, 2008, 2011; Ruiz de Mendoza & Galera, 2014), la Gramática Léxico-Construccional Formalizada (FL_CxG), que allanará el camino para futuros desarrollos computacionales, como analizadores sintácticos o bases de datos léxicas. La FL_CxG despliega (i) el aparato sintáctico orientado tipológicamente de la Gramática de Roles y Referencias (Van Valin, 2005; Van Valin & LaPolla, 1997), (ii) el catálogo de unidades constructivas ordenadas en una tipología de 4 capas, como propone la LCM, y (iii) algunas ideas para las representaciones semánticas de la Teoría del Léxico Generativo (Pustejovsky, 1995; Pustejovsky & Batiukova, 2019), y el Inglés Mínimo (Goddard, 2018). Todos los componentes del FL_CxG (unidades léxicas y construct(ion)s) se codifican formalmente como Estructuras de Características Tipificadas en el formato de Matrices de Valores de Atributos. Estas unidades deben entenderse como restricciones que operan en los procesos de unificación que subyacen a la generación/decodificación de un fragmento dado de la lengua.Cortés-Rodríguez, FJ.; Díaz-Galán, A.

Violencia doméstica: una revisión bibliográfica y bibliométrica

La violencia ejercida entre personas vinculadas por lazos familiares y afectivos ha ganado gran relevancia social en los últimos años. Diversos profesionales han propuesto una gran variedad de conceptos para estudiar el fenómeno, sin que exista hasta el momento un acuerdo sobre lo apropiado de cada uno de éstos. El presente estudio se centra en el análisis de la productividad bibliográfica en torno al término Violencia Doméstica (Domestic Violence), quizás el más arraigado para describir la violencia en la pareja, y ofrece datos sobre años de publicación, país, idioma, sexo de la muestra, grupos de edad, revistas y autores más productivos y la relación víctima-agresor en dichas publicaciones, para finalizar con una reflexión sobre la pertinencia de su uso.Domestic violence: A bibliographic and bibliometric review. Violence among relatives and emotionally linked people has recently made a huge social impact. Professionals have suggested diverse concepts to explain the issue, but they have not yet reached an agreement about these concepts. The present work focuses on the scientific yield associated with the keywords «Domestic Violence», perhaps the most commonly used to refer to violence in romantic couples. A series of related publications is analyzed and data about publication years, countries, languages, sample genders, age groups, most prolific journals and authors, and victim-abuser relationships is provided, along with a reflection upon the correctness of the usage of the keyword

Radiative forcing under mixed aerosol conditions

The mixture of mineral dust with biomass burning or urban-industrial aerosols presents significant differences in optical properties when compared to those of the individual constituents, leading to different impacts on solar radiation levels. This effect is assessed by estimating the direct radiative forcing (ΔF) of these aerosols from solar flux models using the radiative parameters derived from the Aerosol Robotic Network (AERONET). These data reveal that, in oceanic and vegetative covers (surface albedo (SA) 0.30 are not present in East Asia region. At the bottom of atmosphere (BOA) the maximum ΔF values are associated with the highest AOD levels obtained for the mixture of mineral dust and biomass burning aerosols (−130 ± 44 Wm−2 with AOD = 0.8 ± 0.4 for SA < 0.30).Support for this study was given by Spanish Ministry of Education and Science, projects CGL2005‐03428‐C04‐02, CGL2007‐66477‐C02‐02/CLI, PI042005/033, and CGL2008‐04740/CLI

Lactic Acid Bacteria and Yeast Inocula Modulate the Volatile Profile of Spanish-Style Green Table Olive Fermentations

In this work, Manzanilla Spanish-style green table olive fermentations were inoculated with Lactobacillus pentosus LPG1, Lactobacillus pentosus Lp13, Lactobacillus plantarum Lpl15, the yeast Wickerhanomyces anomalus Y12 and a mixed culture of all them. After fermentation (65 days), their volatile profiles in brines were determined by gas chromatography-mass spectrometry analysis. A total of 131 volatile compounds were found, but only 71 showed statistical differences between at least, two fermentation processes. The major chemical groups were alcohols (32), ketones (14), aldehydes (nine), and volatile phenols (nine). Results showed that inoculation with Lactobacillus strains, especially L. pentosus Lp13, reduced the formation of volatile compounds. On the contrary, inoculation with W. anomalus Y12 increased their concentrations with respect to the spontaneous process, mainly of 1-butanol, 2-phenylethyl acetate, ethanol, and 2-methyl-1-butanol. Furthermore, biplot and biclustering analyses segregated fermentations inoculated with Lp13 and Y12 from the rest of the processes. The use of sequential lactic acid bacteria and yeasts inocula, or their mixture, in Spanish-style green table olive fermentation could be advisable practice for producing differentiated and high-quality products with improved aromatic profile.Gobierno de España-OliFilm-AGL-2013-48300-
