With this method, we can calculate the rank distance and sample entropy of microblog data according to the evaluation word rank vector of microblog false information, carry out the block matching of false

Novel insights in the Levy–Levy–Solomon agentbased economic market model Int. J. Mod. Phys. C (IF 1.228) Pub Date : 20201110
Maximilian Beikirch; Torsten TrimbornThe Levy–Levy–Solomon (LLS) model [M. Levy, H. Levy and S. Solomon, Econ. Lett.45, 103 (1994)] is one of the most influential agentbased economic market models. In several publications this model has been discussed and analyzed. Especially Lux and Zschischang [E. Zschischang and T. Lux, Physica A: Stat. Mech. Appl.291, 563 (2001)] have shown that the model exhibits finitesize effects. In this study

AIMpy: A Python code to solve Schrödingerlike equations with the asymptotic iteration method Int. J. Mod. Phys. C (IF 1.228) Pub Date : 20201107
Mesut KarakoçThis paper presents an opensource program called AIMpy built on Python language. AIMpy is a solver for Schrödingerlike differential equations using asymptotic iteration method (AIM). To confirm that the code works seamlessly, it has been shown through the paper, with recalculation of some previously studied eigenvalue examples, that the code can very well reproduce their results.
