As a well-known example of “living fossil,” horseshoe crabs are ecologically significant macroinvertebrates in coastal and estuarine ecosystems. The tri-spine crab, Tachypleus tridentatus , has been widely utilized for amebocyte lysate production food consumption since the 1980s, which led to considerable population declines along west coast Pacific Ocean. declining crab is expected have ecolog...

We consider the roughness properties of NYSE (New York Stock Exchange) stock-price fluctuations. The statistical properties of the data are relatively homogeneous within the same day but the large jumps between different days prevent the extension of the analysis to large times. This leads to intrinsic finite size effects which alter the apparent Hurst (H) exponent. We show, by analytical metho...

Faceless trading in a secondary stock market not only redistributes wealth among investors but also generates information that guides subsequent real decisions. We provide a disclosure model that reflects both functions of the secondary market. By partially preempting traders’information advantage established from information acquisition, disclosure reduces incentives for privately acquiring in...

We propose a mechanism by which the efficiency of mixing in chaotic flows can be enhanced. Our mechanism consists of introducing small changes in the system parameters in regions of phase space where the local Lyapunov exponent falls substantially below its average value. We have applied our mechanism to several typical chaotic maps and flows including a system of chemical reactions. We find th...
