Abstract	Pencil-beam Doppler scatterometers are a promising remote sensing tool for measuring ocean vector winds and currents from space. While several point designs exist in the literature, these designs have been constrained by the hardware they inherited, and the design is sub-optimal. Here, guidelines to optimize the design of these instruments starting from the basic sensitivity equations are presented. Unlike conventional scatterometers or pencil-beam imagers, appropriate sampling of the Doppler spectrum and optimizing the radial velocity error lead naturally to a design that incorporates a pulse-to-pulse separation and pulse length that vary with scan angle. Including this variation can improve radial velocity performance significantly and the optimal selection of system timing and bandwidth is derived. Following this, optimization of the performance based on frequency, incidence angle, antenna length, and spatial sampling strategy are considered. It is shown that antenna length influences the performance most strongly, while the errors depend only on the square root of the transmit power. Finally, a set of example designs and associated performance are presented.

Abstract	La sociedad global está en crisis debido a cambios ambientales, sociales y económicos exacerbados por la propagación de la COVID-19 entre el 2019 y el 2023; sumado a esto el deterioro del sistema financiero del Estado ecuatoriano ocasionando una crisis a nivel local. Este documento es un aporte para generar una reflexión crítica sobre el uso de las regalías obtenidas por conceptos de extracción petrolera que durante los últimos 40 años ha sido el principal rubro que alimenta al Producto Interno Bruto del Ecuador. Estas regalías no se han invertido de manera sostenible en sectores como educación, salud y servicios. Un cambio de la matriz productiva del Estado ecuatoriano debe considerar que los acuerdos nacionales e internacionales incluyendo a los países importadores de hidrocarburos para enfrentar el cambio climático, deben reducir su dependencia de este tipo de energía. A medida que se da esta transición energética, los países del sur global, ven comprometida su economía, pues no cuentan con un plan para enfrentar este escenario. Finalmente, esta crisis sistémica trae enormes desafíos para países en vías de desarrollo como Ecuador, cuya economía está basada en un modelo poco diversificado y extractivista, evidenciándose la necesidad de replantear un nuevo esquema de desarrollo. En este sentido, en el presente artículo: (1) reflexionamos sobre el modelo de crecimiento económico actual vs. el modelo de transición energética planteado desde diversos sectores de la sociedad global, (2) analizamos las conexiones entre el equilibrio ecológico, la salud y la economía global, y la pandemia de COVID-19; y (3) examinamos las alternativas y desafíos económicos basados en el aprovechamiento de la biodiversidad y los servicios ecosistémicos para enfrentar la era post petrolera en el Ecuador. En conclusión: la educación pública en todos sus niveles es una inversión estratégica para cualquier Estado soberano, que tiene como papel fundamental generar las condiciones necesarias para transformar la sociedad y mantener su matriz ...

Abstract	Objetivo: El presente estudio tiene como finalidad evaluar la percepción que tienen los pacientes con artritis reumatoide (AR) con relación a su enfermedad. Métodos: La muestra estuvo representada por 99 pacientes que cumplían con el diagnóstico de AR de acuerdo con los criterios ACR – EULAR 2010 de artritis reumatoide, con un predominio del género femenino de 93% y el promedio de edad fue de 51 años (± 23). Los promedios de DAS 28, HAQ y SF36, fueron de 3,88 (± 2,66), 1,05 (± 0,68) y 57, respectivamente. Resultados: En cuanto a la información aportada por el médico acerca de su enfermedad hubo una diferencia significativa en la percepción entre el grupo que respondió que No la información suministrada por su médico fue clara y suficiente que representó el 77% (N=77) y Si el 22% (N=22), ya que al comparar la media de los participantes se observó una diferencia estadísticamente significativa (p <0,028), evidenciándose que la percepción del paciente en relación con la información suministrada por el médico influenció la puntuación alcanzada. El haber recibido información acerca de su enfermedad tuvo impacto en la puntuación alcanzada, observándose que el grupo que no obtuvo información presentó menor puntuación que la contraparte, con una diferencia significativa (p< 0,001). Conclusión: La educación por parte del médico tratante representa un elemento de valor en el conocimiento de la enfermedad por parte de los pacientes con artritis reumatoide.

Abstract	This paper examines the impact of COVID-19 on bilateral trade flows using a state-of-the-art gravity model of trade. Using the monthly trade data of 68 countries exporting across 222 destinations between January 2019 and October 2020, our results are threefold. First, we find a greater negative impact of COVID-19 on bilateral trade for those countries that were members of regional trade agreements before the pandemic. Second, we find that the impact of COVID-19 is negative and significant when we consider indicators related to governmental actions. Finally, this negative effect is more intense when exporter and importer country share identical income levels. In the latter case, the highest negative impact is found for exports between high-income countries.

Abstract	Soil is one of the main reservoirs of fungi. The aim of this study was to study the richness of ascomycetes in a set of soil samples from Mexico and Spain. Fungi were isolated after 2% w / v phenol treatment of samples. In that way, several strains of the genus Penicillium were recovered. A phylogenetic analysis based on internal transcribed spacer (ITS), beta-tubulin ( BenA ), calmodulin ( CaM ), and RNA polymerase II subunit 2 gene ( rpb 2) sequences showed that four of these strains had not been described before. Penicillium melanosporum produces monoverticillate conidiophores and brownish conidia covered by an ornate brown sheath. Penicillium michoacanense and Penicillium siccitolerans produce sclerotia, and their asexual morph is similar to species in the section Aspergilloides (despite all of them pertaining to section Lanata - Divaricata ). P. michoacanense differs from P. siccitolerans in having thick-walled peridial cells (thin-walled in P. siccitolerans ). Penicillium sexuale differs from Penicillium cryptum in the section Crypta because it does not produce an asexual morph. Its ascostromata have a peridium composed of thick-walled polygonal cells, and its ascospores are broadly lenticular with two equatorial ridges widely separated by a furrow. All four new species are xerophilic. Despite the genus Penicillium containing more than 480 known species, they are rarely reported as xerophilic.

Abstract	The kinetic energy transfer between the atmosphere and oceans, called wind work, affects ocean dynamics, including near-inertial oscillations and internal gravity waves, mesoscale eddies, and large-scale zonal jets. For the most part, the recent numerical estimates of global wind work amplitude are almost five times larger than those reported 10 years ago. This large increase is explained by the impact of the broad range of spatial and temporal scales covered by winds and currents, the smallest of which has only recently been uncovered by increasingly high-resolution modeling efforts. However, existing satellite observations do not fully sample this broad range of scales. The present study assesses the capabilities of ODYSEA, a conceptual satellite mission to estimate the amplitude of wind work in the global ocean. To this end, we use an ODYSEA measurement simulator fed by the outputs of a km scale coupled ocean–atmosphere model to estimate wind work globally. The results indicate that compared with numerical truth estimates, the ODYSEA instrument performs well globally, except for latitudes north of 40 <semantics> ∘ </semantics> N during summer due to unresolved storm evolution. This performance is explained by the wide-swath properties of ODYSEA (a 1700 km wide swath with 5 km posting for winds and surface currents), its twice-a-day (daily) coverage at mid-latitudes (low latitudes), and the insensitivity of the wind work to uncorrelated errors in the estimated wind and current.

Abstract	The climate change impact and adaptation communities need future scenarios with sufficient high resolution, which are frequently achieved by applying Statistical Downscaling Models (SDMs) over global climate models. A large variety of SDMs exists, and some can be more suitable than others for each specific purpose. For this reason, it is important to develop tools to facilitate the evaluation and generation of downscaled scenarios following different approaches. In this paper we present a service, ‘pyClim-SDM’, which allows users to generate and evaluate their own downscaled scenarios with a very simple and user-friendly graphical interface. This tool includes a large collection of state-of-the-art methods belonging to different families to downscale daily data of the following surface variables: temperature, precipitation, wind, relative humidity and cloud coverage. Additionally, the software is prepared to be applied over any other user-defined target variable. Thus, multivariable indexes can be tackled as target variables themselves, instead of being calculated from the downscaled primary variables. With this possibility, potential intervariable inconsistencies are avoided. An application example for a Fire Weather Index, dependent on temperature, wind, humidity and precipitation, is shown. The service here presented -mainly based on a new downscaling software and a user-friendly graphical interface- is an essential piece for evaluating and generating high-resolution projection data within the Spanish national climate change adaptation strategy which includes, among other elements, a common database for all sectors, viewer and data distribution portal, etc.
