Real world markets display power-law features in variables such as price fluctuations in stocks. To further understand market behavior, we have conducted a series of market experiments on our web-base...
A new mechanism for the electromagnetic transition γ*N→N*(1535)
N*(1535) electromagnetic transition helicity amplitudes
font style='font-size:12px;'>
2010/5/7
The helicity amplitude Ap1/2 for the electromagnetic transition γ* N→N*(1535) is investigated. It is found that a new mechanism γ*→qq plays an important role in order to improve the description of thi...

Stony corals build hard skeletons of calcium carbonate (CaCO3) by combining calcium with carbonate ions derived, ultimately, from seawater. The concentration of carbonate ions relative to other carbon...
A mechanism for switching near a heteroclinic network
heteroclinic network switching

2010/4/8
We describe an example of a structurally stable heteroclinic network for which nearby orbits exhibit irregular but sustained switching between the various sub-cycles in the network. The mechanism for ...
Solitary wave in a Burridge-Knopoff model with slip-dependent friction as a clue to understanding the mechanism of the self-healing slip pulse in an earthquake rupture process
Solitary wave Burridge-Knopoff model slip-dependent friction earthquake rupture process
