Spectrograms of baleen whale records synthesized from Autoenconder architectures: CAE, VAE and CAE-LSTM

Revista Elektrón, 2022
In this paper, different architectures of simple convolutional networks are analyzed to generate synthetic spectrograms corresponding to baleen whales. Simplicity in these models plays an important role in the implementations of these type of networks on

Estudio comparativo de la heteroestructura CuO/CuWO₄ y los óxidos CuO y CuWO₄: validación de aplicaciones fotocatalíticas

Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales
Se presenta un estudio comparativo de las propiedades estructurales, morfológicas y ópticas de la heteroestructura CuO/CuWO₄ y las de estos óxidos individuales. Un primer análisis estructural semicuantitativo reveló la formación de las fases CuO

Ruiz Artola, Inés: Formiści, la síntesis de la modernidad (1917-1922). Conexiones y protagonistas.

Boletín de Arte, 2016
Libargo (2015), responde claramente a un estudio pormenorizado de un aspecto de las vanguardias artísticas europeas que ha pasado apenas desapercibido por la historiografía española: la revista polaca Formisci (1919-1921), precursora del arte moderno en ...

Nueva recurrencia periódica. A tale of 7 elements

Educación Química, 2018
Se dice que cada vez menos gente lee, lo cual puede que no sea del todo cierto si se considera que nunca habíamos existido tantos seres humanos; pero, de lo que no cabe duda, es que cada vez más gente escribe.

Chemoselective Aldehyde and Imine Reduction by a Macrocyclic Triazole–Borane Complex Triggered by a Non‐innocent Proton–Hydride Interaction

European Journal of Organic Chemistry, EarlyView.
This work describes the study on a new recyclable reagent, based on a macrocyclic triazole–borane complex. It showed high chemoselectivity for aldehyde reduction and reductive amination over ketones. This selectivity is driven by a noncovalent hydride–proton interaction that stabilizes the transition state for aldehydes but is sterically inhibited in ...

Statistical Downscaling of Daily Temperature and Precipitation From Regional Climate Models in Complex Mountain Terrain

International Journal of Climatology, EarlyView.
The study provides insights for post‐processing climate model output in complex terrain, useful for climate change impact models. We compared different bias adjustment and downscaling techniques from quantile delta mapping to simple lapse rates. We developed a new spatial downscaling method based on principal components analysis, which showed superior ...

Unpacking the task of synthesis when weaving knowledge systems for biodiversity assessments

People and Nature, EarlyView.
Abstract The pivot towards evidence‐based conservation since 2000 has inspired global environmental assessments to gather evidence across multiple knowledge systems, including through co‐production with Indigenous Peoples and local communities. Knowledge co‐production is highlighted as a strategy for transformative change towards a just future that ...

Síntesis de un pigmento rojo a partir de nanopartículas de oro

Boletín de la Sociedad Española de Cerámica y Vidrio, 2012
A simple method of synthesising red pigments for ceramic glazes, based on gold nanoparticles protected by a refractory oxide capsule, was developed. Gold nanoparticles of an appropriate size were obtained by reaction in an aqueous medium between an Au ...

‘Childish’ and ‘Minors’? Deconstructing Prejudice and Identity Transformation Among Spanish Women Religious During the Long Sixties1

Gender &History, EarlyView.
ABSTRACT This article explores the identity formation process undertaken by Spanish women's religious following the aggiornamento promoted by the Second Vatican Council. Specifically, it seeks to examine the context in which these women lived and acted, analysing the construction of their identities, their capacity for agency and transgression within ...
