With the development of intelligent and automated information system in the information era,
the need for more efficient decision making method is growing. An effective method used to …

We derive the asymptotic expression for the number of labeled 2-connected planar graphs
with respect to vertices and edges. We also show that almost all such graphs with $ n $ …

The current understanding of how ecosystem services flow affects human well-being is not
sufficient. As an important component of the biogeochemical cycle, carbon flows through …

Combined exposure of chronic stress and alumina nanoparticles (AlNPs) aggravates
hippocampal injury, but the pathogenesis is unevaluated. This study aimed to investigate the effect …

The natural biomaterial sarcosine as an electron transport layer (ETL) to modify ITO or ITO/ZnO
