The sample was compiled from the QDOT redshift survey, the 1 Jy ULIRGs survey and a sample obtained by a cross-correlation study of the IRAS Point Source ... More
A short note on the axiomatic requirements of uncertainty measureOct 08 2013In this note, we argue that the axiomatic requirement of range to the measure of aggregated total uncertainty (ATU) in Dempster-Shafer theory is not reasonable.
Towards experimental entanglement connection with atomic ensembles in the single excitation regimeApr 17 2007We present a protocol for performing entanglement connection between pairs of atomic ensembles in the single excitation regime. Two pairs are prepared in an asynchronous fashion and then connected via a Bell measurement. The resulting state of the two ... More
The Time Invariance Principle, Ecological (Non)Chaos, and A Fundamental Pitfall of Discrete ModelingFeb 23 2007Mar 09 2007This paper is to show that most discrete models used for population dynamics in ecology are inherently pathological that their predications cannot be independently verified by experiments because they violate a fundamental principle of physics. The result ... More
The Origin of 2 Sexes Through Optimization of Recombination Entropy Against Time and EnergyMar 09 2007Sexual reproduction in Nature requires two sexes, which raises the question why the reproductive scheme did not evolve to have three or more sexes. Here we construct a constrained optimization model based on the communication theory to analyze trade-offs ... More
Mechanistic Model to Replace Hodgkin-Huxley EquationsMay 13 2015In this paper we construct a mathematical model for excitable membranes by introducing circuit characteristics for ion pump, ion current activation, and voltage-gating. The model is capable of reestablishing the Nernst resting potentials, all-or-nothing ... More
