Pulse Dynamics in a Bistable Reaction-Diffusion System with Chemotaxis by Satoshi Kawaguchi

“…We consider pulse dynamics in a bistable reaction-diffusion system with chemotaxis. We derive the ordinary differential equation of interfaces by applying the multiple scales method to the reaction-diffusion system for examining the effect of the chemotaxis on pulse dynamics in one dimension. …”

Dynamics of Fuzzy BAM Neural Networks with Distributed Delays and Diffusion by Qianhong Zhang, Lihui Yang, Jingzhong Liu

“…Constructing a new Lyapunov functional and employing inequality technique, the existence, uniqueness, and global exponential stability of the periodic oscillatory solution are investigated for a class of fuzzy bidirectional associative memory (BAM) neural networks with distributed delays and diffusion. We obtained some sufficient conditions ensuring the existence, uniqueness, and global exponential stability of the periodic solution. …”

Turing Patterns in a Predator-Prey System with Self-Diffusion by Hongwei Yin, Xiaoyong Xiao, Xiaoqing Wen

“…However, in the real world, the tendency for prey and predators moving along the direction of lower density of their own species, called self-diffusion, should be considered. For this, we investigate Turing instability for a predator-prey system with nonlinear diffusion terms including the normal diffusion, cross-diffusion, and self-diffusion. …”

Pattern Formation in a Cross-Diffusive Holling-Tanner Model by Weiming Wang, Zhengguang Guo, R. K. Upadhyay, Yezhi Lin

“…Furthermore, we present novel numerical evidence of time evolution of patterns controlled by self- as well as cross-diffusion in the model, and find that the model dynamics exhibits a cross-diffusion controlled formation growth not only to spots, but also to strips, holes, and stripes-spots replication. …”

La diffusion spatiale de l’informatique en Inde by Divya Leducq

“…Beyond the fact that InfoTech are seen as a trickle-down development engine, it is the cluster which has become gradually a town planning measure in the sectoral policies followed by the central government and the regional states. The diffusion of this spatial model can be explained by the success stories which made the reputation of India and the expected benefits in terms of innovation. …”

Evaluation of effective diffusivity correlations for soybeans in thin layer drying by Felipe d'Avila, Rafael Maurício Urnau, Amanda Mansano Zanella Blauth, Marcos Flávio Pinto Moreira

“…The correlation proposed by Dotto et al. (2018) was the one with the lowest average error (0.048%) for the consideration of an average effective diffusivity. In order to consider a punctual effective diffusivity, modifications were made to the Dotto model, providing a maximum error of 2.6%. …”
