Fractal Markets Hypothesis and the Global Financial Crisis: Wavelet Power Evidence [PDF]
Scientific Reports, 2013 We analyze whether the prediction of the fractal markets hypothesis about a dominance of specific investment horizons during turbulent times holds. To do so, we utilize the continuous wavelet transform analysis and obtained wavelet power spectra which give the crucial information about the variance distribution across scales and its evolution in time ...

The Higher Land Prices, the Worse Emission Performance? Theory and Evidence
Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.This study investigates whether high land prices in China have worsened polluting enterprises’ emission performance. Our model confirms that increases in pollution intensity led by rising land prices are the result of fewer resources being directed to abatement investments, which corresponds to smaller declines in emissions versus output.

Assessment of Life Safety Risk in Building Fires With an Integrated Fire and Evacuation Model
Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.This paper presents an integrated simulation methodology that combines fire hazard modeling with pedestrian evacuation analysis to evaluate how tenability conditions affect occupant egress. In the proposed approach, fire scenarios representative of leisure and spa resorts are modeled using the Fire Dynamics Simulator (FDS).

Forecasting Stock Return Based on the Multifactor Dynamic Attention Network
Discrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.The application of multifactor models for forecasting stock returns has become a relatively mature practice in the financial field. The assumption of no collinearity among factors in some existing research may lead to the loss of stock information. In order to address this issue, a novel multifactor model, the multifactor dynamic attention network ...
