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...
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...
Population forces: Sexual antagonisms, dominant genetic effects Guess: William Rice, 1984, Evolution; Brian Charlseworth et al, 1987, Am Nat Vibranovski M et al, 2009, PLoS Genetics (In press): Stag...
We present a general concept of mechanisms of preseismic phenomena in the atmosphere and ionosphere. After short review of observational results we conclude: 1. Upward migration of fluid substrate mat...
paper proposes a generic design principle for generating robust traits in complex systems that requires two basic conditions to be satisfied: 1) agents are versatile enough to perform more than one si...
The nonlinear mechanism of long gravitational surface water wave generation by high-frequency bottom oscillations in a water layer of constant depth is investigated analytically. The connection betwee...
The problem of tsunami wave generation by variable meteo-conditions is discussed. The simplified linear and nonlinear shallow water models are derived, and their analytical solutions for a basin of co...
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       font style='font-size:12px;'> 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 ...
A one-dimensional Burridge-Knopoff spring-block model with slip-dependent friction was studied to explore the possibility of a solitary wave solution existing for the problem of earthquake faulting. T...
Modulation of short surface ripples by long surface or internal waves by a cascade mechanism is considered. At the first stage, the orbital velocity of the long wave (LW) adiabatically modulates an in...
Clarification is offered of the energy transfer role played by the Hall effect in a recent paper: de Paor, A., A theory of the Earth's magnetic field and of sunspots, based on a self-excited dynamo in...
Biomass burning in the Indochina Peninsula (Indochina) is one of the important ozone sources in the low troposphere over East Asia in springtime. Moderate Resolution Imaging Spectroradiometer (MODIS) ...
MECHANISM OF GROUND WATER RESERVOIRS      MECHANISM  GROUND WATER RESERVOIRS        font style='font-size:12px;'> 2009/10/29
The article deals with unsteady ground water flow in an aquifer of limited horizontal extent. The changes in storage are taken to be dependent on a storage coefficient S, and flow rates are taken to...
The physical problem dealt with in this article is the unsteady groundwater flow in an aquifer of limited horizontal extent and arbitrary boundary shape.The unsteady ground-water level is described ...
