Novel Degree-Based Topological Descriptors of Fenofibrate Using M-Polynomial
Journal of Mathematics, 2023 Chemical graph theory is currently expanding the use of topological indices to numerically encode chemical structure. The prediction of the characteristics provided by the chemical structure of the molecule is a key feature of these topological indices ...

Insect Conservation and Diversity, EarlyView.Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.
