Universal collective fluctuations in gene expression dynamics from yeast to human
J. C. Nacher, T. Ochiai, T. Akutsu
In this work, the dynamics of fluctuations in gene expression time series is investigated. By using collected data of gene expression from yeast and human organisms, we found that…
Symmetry and Dynamics in living organisms: The self-similarity principle governs gene expression dynamics
T. Ochiai, J. C. Nacher, T. Akutsu
The ambitious and ultimate research purpose in Systems Biology is the understanding and modelling of the cell's system. Although a vast number of models have been developed in orde…
Flexible construction of hierarchical scale-free networks with general exponent
J. C. Nacher, N. Ueda, M. Kanehisa +1
Extensive studies have been done to understand the principles behind architectures of real networks. Recently, evidences for hierarchical organization in many real networks have al…
Clustering under the line graph transformation: Application to reaction network
J. C. Nacher, N. Ueda, T. Yamada +2
Many real networks can be understood as two complementary networks with two kind of nodes. This is the case of metabolic networks where the first network has chemical compounds as…
Two complementary representations of a scale-free network
J. C. Nacher, T. Yamada, S. Goto +2
Several studies on real complex networks from different fields as biology, economy, or sociology have shown that the degree of nodes (number of edges connected to each node) follow…
Two pion photoproduction on nucleons and nuclei in the rho and sigma regions
E. Oset, L. Roca, M. J. Vicente Vacas +1
In this talk we report on two physical processes, the photoproduction of mesons in nuclei and the photoproduction in nuclei at low energies. In the first case the aim…
