Big pyridyl Schiff base π-conjugated skeleton based cobalt/iron metal complexes: a bimetallic electrocatalyst for oxygen evolution reaction Schiff base metal complexes exhibit huge potential as efficient electrocatalysts for oxygen evolution reaction (OER). However, the high overpotential and complex synthesis process largely restrict their practical application.

5. Discussion 5.1. Uncertainty Analysis of Automatic Land Cover Mapping Based on Model MigrationIn order to explore the uncertainties in the automated land cover mapping based on the model migration strategy, we used validation samples () where the land cover type did not change between 2010 and 2020 to quantitatively analyze the spectral differences in each land cover type in the two study areas during the period from 2010 to 2020.

1 INTRODUCTION With the widespread adoption in breast cancer screening, the incidence of ductal carcinoma in situ (DCIS) was accounting for 25% of all new cancer cases,1 with 10% of them presenting in combination with ductal carcinoma in situ with microinvasion (DCIS-MI).2 According to the 8th edition of the American Joint Committee on Cancer (AJCC) staging system for breast cancer, DCIS-MI is defined by the presence of cancer cells that have penetrated the basement membrane and invaded...

AbstractChina’s extensive planted forests play a crucial role in carbon storage, vital for climate change mitigation. However, the complex spatiotemporal dynamics of China’s planted forest area and its carbon storage remain uncaptured. Here we reveal such changes in China’s planted forests from 1990 to 2020 using satellite and field data. Results show a doubling of planted forest area, a trend that intensified post-2000.
