1. Modeling Financial Markets by Self-Organized Criticality

Alessandro Pluchino (CT)

We present a self-organized criticality (SOC) model to study herding and avalanche dynamics in financial markets. We first consider a community of interacting investors, distributed in a small-world network, who bet on the bullish (increasing) or bearish (decreasing) behavior of an exogenous real market. Then we modify the model in order to generate endogenously a realistic price dynamics and...

12. Self-organized Bistability

Mrs Serena Di Santo (Università di Parma)

Self-organized criticality elucidates the conditions under which systems tune themselves to the edge of a second-order phase transition, with scale invariance. Motivated by the empirical observation of bimodal activity-burst distributions in neuroscience and other fields, we propose and analyze a theory for the self-organization to the point of phase-coexistence in systems exhibiting a...

23. Stochastic model of CPEB3 oligomerization for synaptic facilitation and LTM formation

Dr Elena Tea Russo (UNIBO)

CPEB3 is a mammalian prion-like protein of the CPEB family, which has been shown to mediate local protein synthesis in the synaptic facilitation and Long Term Memory (LTM) formation both in vitro and in vivo. Moreover, it has been observed that SUMOYlayion of CPEB3 regulates its oligomerization and activity. In the basal state, SUMOylated CPEB3 is the most abundant among CPEB3 forms, while...
