Title A name given to the resource Hybrid Biopolymer and Lipid Nanoparticles with Improved Transfection Efficacy for mRNA Creator An entity primarily responsible for making the resource Christian D. Siewert, Heinrich Haas, Vera Cornet, Sara S. Nogueira, Thomas Nawroth, Lukas Uebbing, Antje Ziller, Jozef Al-Gousous, Aurel Radulescu, Martin A. Schroer, Clement E. Blanchet, Dmitri I. Svergun, Markus P. Radsak, Ugur Sahin, Peter Langguth Description An account of the resource Hybrid nanoparticles from lipidic and polymeric components were assembled to serve as vehicles for the transfection of messenger RNA (mRNA) using different portions of the cationic lipid DOTAP (1,2-Dioleoyl-3-trimethylammonium-propane) and the cationic biopolymer protamine as model systems. Two different sequential assembly approaches in comparison with a direct single-step protocol were applied, and molecular organization in correlation with biological activity of the resulting nanoparticle systems was investigated. Differences in the structure of the nanoparticles were revealed by thorough physicochemical characterization including small angle neutron scattering (SANS), small angle X-ray scattering (SAXS), and cryogenic transmission electron microscopy (cryo-TEM). All hybrid systems, combining lipid and polymer, displayed significantly increased transfection in comparison to lipid/mRNA and polymer/mRNA particles alone. For the hybrid nanoparticles, characteristic differences regarding the internal organization, release characteristics, and activity were determined depending on the assembly route. The systems with the highest transfection efficacy were characterized by a heterogenous internal organization, accompanied by facilitated release. Such a system could be best obtained by the single step protocol, starting with a lipid and polymer mixture for nanoparticle formation.

Title A name given to the resource Hybrid Deep Learning-Based Epidemic Prediction Framework of COVID-19: South Korea Case Creator An entity primarily responsible for making the resource Firda Rahmadani, Hyunsoo Lee Description An account of the resource The emergence of COVID-19 and the pandemic have changed and devastated every aspect of our lives. Before effective vaccines are widely used, it is important to predict the epidemic patterns of COVID-19. As SARS-CoV-2 is transferred primarily by droplets of infected people, the incorporation of human mobility is crucial in epidemic dynamics models. This study expands the susceptible–exposed–infected–recovered compartment model by considering human mobility among a number of regions. Although the expanded meta-population epidemic model exhibits better performance than general compartment models, it requires a more accurate estimation of the extended modeling parameters. To estimate the parameters of these epidemic models, the meta-population model is incorporated with deep learning models. The combined deep learning model generates more accurate modeling parameters, which are used for epidemic meta-population modeling. In order to demonstrate the effectiveness of the proposed hybrid deep learning framework, COVID-19 data in South Korea were tested, and the forecast of the epidemic patterns was compared with other estimation methods.

Title A name given to the resource Hybrid Dual-Polarization Synthetic Aperture Radar Creator An entity primarily responsible for making the resource R. Keith Raney Description An account of the resource Compact polarimetry for a synthetic aperture radar (SAR) system is reviewed. Compact polarimetry (CP) is intended to provide useful polarimetric image classifications while avoiding the disadvantages of space-based quadrature-polarimetric (quad-pol) SARs. Two CP approaches are briefly described, &#960;/4 and circular. A third form, hybrid compact polarimetry (HCP) has emerged as the preferred embodiment of compact polarimetry. HCP transmits circular polarization and receives on two orthogonal linear polarizations. When seen through its associated data processing and image classification algorithms, HPC&#8217;s heritage dates back to the Stokes parameters (1852), which are summarized and explained in plain language. Hybrid dual-polarimetric imaging radars were in the payloads of two lunar-orbiting satellites, India&#8217;s Earth-observing RISAT-1, and Japan&#8217;s ALOS-2. In lunar or planetary orbit, a satellite equipped with an HCP imaging radar delivers the same class of polarimetric information as Earth-based radar astronomy. In stark contrast to quad-pol, compact polarimetry is compatible with wide swath modes of a SAR, including ScanSAR. All operational modes of the SARs aboard Canada&#8217;s three-satellite Radarsat Constellation Mission (RCM) are hybrid dual-polarimetric. Image classification methodologies for HCP data are reviewed, two of which introduce errors for reasons explained. Their use is discouraged. An alternative and recommended group of methodologies yields reliable results, illustrated by polarimetrically classified images. A survey over numerous quantitative studies demonstrates HCP polarimetric classification effectiveness. The results verify that the performance accuracy of the HCP architecture is comparable to the accuracy delivered by a quadrature-polarized SAR. Four appendices are included covering related topics, including comments on inflight calibration of an HCP radar.

Title A name given to the resource Hybridization Chain Reactions Targeting the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Creator An entity primarily responsible for making the resource Wei-Yin Lin, Chii-Wann Lin, Chia-Chen Chang, Ching-Hsu Yang, Tzu-Heng Wu, Tan Joy Ee Description An account of the resource In this work, hybridization chain reactions (HCRs) toward Severe Acute Respiratory Syndrome Coronavirus 2 (SARS–CoV-2) nucleocapsid phosphoproteins gene loci and human RNase P are proposed to provide an isothermal amplification screening tool. The proposed chain reactions target the complementary DNA (cDNA) of SARS–CoV-2, with loci corresponding to gold-standard polymerase chain reaction (PCR) loci. Four hybridization chain reaction reactions are demonstrated herein, targeting N1/N2/N3 loci and human RNase P. The design of the hybridization chain reaction, herein, is assisted with an algorithm. The algorithm helps to search target sequences with low local secondary structure and high hybridization efficiency. The loop domain of the fuel hairpin molecule H1 and H2, which are the tunable segments in such reactions, are used as an optimization parameter to improve the hybridization efficiency of the chain reaction. The algorithm-derived HCR reactions were validated with gel electrophoresis. All proposed reactions exhibit a hybridization complex with a molecular mass >1.5k base pairs, which is clear evidence of chain reaction. The hybridization efficiency trend revealed by gel electrophoresis corresponds nicely to the simulated data from the algorithm. The HCR reactions and the corresponding algorithm serve as a basis to further SARS–CoV-2 sensing applications and facilitate better screening strategies for the prevention of on-going pandemics.

Title A name given to the resource Hydro-meteorological data analysis using OLAP techniques Creator An entity primarily responsible for making the resource Jorge Julián Vélez, Néstor Darío Duque-Méndez, Mauricio Orozco-Alzate Description An account of the resource La riqueza de los datos registrados por las redes de estaciones hidrometeorológicas ofrece una gran oportunidad para analizar, conocer y entender mejor las variables hidroclimatológicas. Por lo tanto, el almacenamiento eficiente de los datos y su tratamiento eficaz son un requisito previo para la investigación meteorológica e hidrológica que requiere de estrategias para que la captación, transmisión, almacenamiento y procesamiento de datos que garanticen su calidad y consistencia. El propósito de este trabajo es desarrollar un modelo conceptual para una bodega de datos diseñada en un esquema en estrella que permita el almacenamiento estructurado y el análisis multidimensional de series históricas de datos hidroclimatológicos. La información registrada por las redes telemétricas de estaciones hidrometeorológicas existentes en Manizales y en el Departamento de Caldas son la fuente de información. El esquema de bodega de datos propuesto aprovecha los datos disponibles (en algunos casos más de 50 años) con el fin de aplicar procesamiento analítico en línea (OLAP) para analizar la calidad de la información y descubrir relaciones ocultas entre las variables, en una región particularmente afectada por el cambio climático y especialmente por fenómenos de variabilidad climática. La principal contribución de este documento abarca la exploración de alternativas a los métodos tradicionales de almacenamiento y análisis de información y la presentación de un número de casos que demuestran la eficacia del modelo propuesto en la evaluación de la calidad de los datos y de la visualización de las relaciones entre las diversas variables a diferentes escalas y para casos específicos.

Title A name given to the resource Hydrogen peroxide, superoxide, lipid peroxidation and membrane damage in leaves of the tree Prosopis nigra (Fabaceae) under simulated glyphosate drift Creator An entity primarily responsible for making the resource Diego Ariel Meloni, Graciela Inés Bolzón Description An account of the resource Introduction: The tree Prosopis nigra is native to the Western Chaco phytogeographic region, affected by the application of glyphosate in the surrounding crops. Objective: To determine the impact of simulated glyphosate drift on growth, photosynthesis and oxidative stress in P. nigra seedlings. Methods: We simulated drift in seedlings at doses of 0, 200, 400 and 800 g a.e. ha-1 of glyphosate. We also measured gas exchange and modulated fluorescence emission of chlorophyll a. Results: Glyphosate reduced biomass, photosynthetic rate, and stomatal conductance. Doses of 400 and 800 g a.e. ha-1 glyphosate produced photoinhibition. The electron transport rate was sensitive to glyphosate, and it decreased at all doses of the herbicide. Glyphosate generated oxidative stress, and produced damage to membranes, because of the accumulation of H2O2 and O2.. Conclusions: Glyphosate reduces growth and photosynthesis in these seedlings. The inhibition of photosynthesis is due to stomatal closure, and alterations in the photochemical stage, associated with oxidative stress.  Date A point or period of time associated with an event in the lifecycle of the resource 2021 Subject The topic of the resource Algarrobo negro, Ecophysiology, antioxidants, herbicides, photosynthesis Identifier An unambiguous reference to the resource within a given context 10.22458/urj.v13i1.3170 Source A related resource from which the described resource is derived Cuadernos de investigación UNED Publisher An entity responsible for making the resource available Universidad Estatal a Distancia (UNED) Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant General Works Relation A related resource <a href="https://revistas.uned.ac.cr/index.php/cuadernos/article/view/3170" target="_blank" rel="noreferrer noopener">https://revistas.uned.ac.cr/index.php/cuadernos/article/view/3170</a> https://socictopen.socict.org/files/original/3ac118cce6e268232b09f753c140c509.pdf 7f197d63791a3e7ac04ad3ba16629439 Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource Hydrologic response of the drainage basins that intersect Las Grutas town, Argentina Creator An entity primarily responsible for making the resource Sibila A. Genchi, María E. Carbone, María C. Piccolo, Gerardo M. E. Perillo Description An account of the resource La localidad de Las Grutas está emplazada en una región semiárida, en la costa Noroccidental del Golfo San Matías (Argentina) y es intersectada por dos cuencas de drenaje que responden ante eventos de precipitaciones intensas. Estos eventos generan flujos capaces de producir riesgos de inundación local, tal como la inundación de abril de 2004. El objetivo de este trabajo es establecer el comportamiento hidrográfico de dichas geoformas y la manera en el cual los usos de la tierra interactúan con ellas. La falta de registros hidrométricos conduce a explicar y predecir respuestas a través de aproximaciones empíricas como el análisis morfométrico fluvial y el número de curva del Servicio de Conservación del Suelo de los Estados Unidos (1972), apoyados en sistemas de información geográfica. El área en estudio presenta características que favorecen la concentración del escurrimiento en cauces durante eventos extremos. Los segmentos de primer orden juegan un rol importante en la respuesta hidrológica. El efecto de la urbanización produce un efecto adicional del 17.3 y 2.1% de escurrimiento en cada cuenca. El incremento potencial del número de eventos extremos en el futuro debido al cambio climático, podría conducir a mayores perturbaciones en el área urbanizada. Los resultados contribuirán a implementar medidas que mitiguen posibles consecuencias de los peligros de inundación.

Title A name given to the resource Hydroterritorial Configuration and Confrontation: The Daule-Peripa Multipurpose Hydraulic Scheme in Coastal Ecuador Creator An entity primarily responsible for making the resource Juan Pablo Hidalgo-Bastidas, Rutgerd Boelens, Edgar Isch Description An account of the resource There is a forceful new impetus toward mega-hydraulic projects in Latin America, which are booming but also highly controversial. They bring benefits to some social groups while many others are negatively affected. Technocratic discourses are dominant in the region; they strategically mobilize institutions, infrastructure, money, and knowledge to present particular hydrosocial territorial imaginaries—such as multipurpose dams—as natural, universal, and politically neutral. Meanwhile, affected local communities commonly envision and practice different discourses, values, and worldviews, based on contextualized notions of well-being and territoriality. Using a political ecology perspective, this article examines how the Daule-Peripa mega-hydraulic scheme—Ecuador’s “hydraulic heart”—has de- and repatterned the territory, producing new hierarchical relations and unequal distribution of socioenvironmental impacts. Though political discourses have changed throughout state-centralist and neoliberal époques, governmental policies and practices have continued and renewed their defense of mega-hydraulism. In turn, affected communities and families, through everyday territorial politics, respond and aim to rearrange the hydrosocial network in order to regain control over water, land, and territorial services. En América Latina hay un nuevo auge de proyectos megahidráulicos que, simultáneamente es muy controversial. Estos proyectos benefician a algunos grupos sociales, mientras que muchos otros son afectados negativamente. Junto a éstos, se movilizan estratégicamente instituciones, infraestructura, dinero y conocimiento con el fin de presentar a imaginarios hidro-sociales particulares como naturales y políticamente neutros. Al mismo tiempo, las comunidades afectadas practican y reproducen diferentes discursos y formas de valoración, fundamentadas en nociones situadas de bienestar y territorialidad. Desde la ecología política y la literatura crítica sobre neoextractivismo, este artículo muestra cómo el megasistema multipropósito Daule-Peripa –corazón hidráulico del Ecuador– ha transformado el territorio, involucrando nuevas relaciones jerárquicas y la distribución inequitativa de impactos socio-ambientales. A pesar de que los discursos oficialistas han cambiado desde la época neoliberal, las políticas y prácticas de gobierno se han renovado y continúan defendiendo y promocionando el imperativo megahidráulico durante regímenes autodenominados progresistas, como el liderado por la llamada revolución ciudadana. Este articulo muestra la importancia de entender el auge contemporáneo de megasistemas hidráulicos como construcciones sociotécnicas desde una perspectiva repolitizada e histórica.
