Correlations and Omori law in Spamming
The most costly and annoying characteristic of the e-mail communication system is the large number of unsolicited commercial e-mails, known as spams, that are continuously received. Via the investigation of the statistical properties of the spam delivering intertimes, we show that spams delivered to a given recipient are time correlated: if the intertime between two consecutive spams is small (...

The role of the stock market in allocating resources in the economy has been limited and ineffective. The most successful part of the financial system, in terms of supporting the growth of the overall economy, is a shadow banking sector that c...
متن کاملMagnitude-Dependent Omori Law: Empirical Study and Theory
We propose a new physically-based “multifractal stress activation” model of earthquake interaction and triggering based on two simple ingredients: (i) a seismic rupture results from activated processes giving an exponential dependence on the local stress; (ii) the stress relaxation has a long memory. The combination of these two effects predicts in a rather general way that seismic decay rates ...
متن کاملDouble Power Law Decay of the Persistence in Financial Markets
Abstract The persistence phenomenon is studied in the Japanese financial market by using a novel mapping of the time evolution of the values of shares quoted on the Nikkei Index onto Ising spins. The method is applied to historical end of day data from the Japanese stock market during 2002. By studying the time dependence of the spins, we find clear evidence for a double-power law decay of the ...
