The present research presents an extended evacuation field model for simulating crowd emergency evacuation processes under the control of evacuation assistants. Furthermore, a communication field for describing the escape information transmission process and its effect on evacuees is introduced....

In the dynamic floor field model, the bosons are homogeneous. This causes a problem that the pedestrians are confused by their own traces. The model has been modified by the heterogeneous bosons. Compared with the dynamic floor field model based on the homogeneous bosons, the modified model...

The game-theoretic approach is an essential tool in the research of conflicts of human behaviors. The aim of this study is to research crowd dynamic conflicts during evacuation processes. By combining a conflict game with a Cellular Automata model, the following factors such as rationality,...

As a response to ligand binding, transmembrane cell receptors often enhance their clustering, or oligomerization, during the signalling process. Here we present a statistical mechanical model which combines the aspects of both clustering and signalling. In this model, receptors float on the...

Distributions of triplets in some genetic sequences are examined and found to be well described by a two-parameter Markov process with a sparse transition matrix. The standard deviations of all the relevant parameters are not large, indicating that most sequences gather in a small region in the...
