The microscopic molecular characteristic will impact on the mechanical property of hydrate. Thus, dynamics simulation is employed to investigate and methane hydrate/ water/ ice mixture system. brittle fracture occurred during tensile deformation Besides, maximum stress system lower than that intact hydrate strain studied smaller pure order parameters F3 F4 can be used for determining position c...

Given a graph G, an incidence matrix N (G) is defined on the set of distinct isomorphism types of induced subgraphs of G. It is proved that Ulam’s conjecture is true if and only if the N -matrix is a complete graph invariant. Several invariants of a graph are then shown to be reconstructible from its N -matrix. The invariants include the characteristic polynomial, the rank polynomial, the numbe...

We study a flexible class of finite disc process models with interaction between the discs. We let U denote the random set given by the union of discs, and use for the disc process an exponential family density with the canonical sufficient statistic only depending on geometric properties of U such as the area, perimeter, Euler-Poincaré characteristic, and number of holes. This includes the qua...

There are two notions of exponent finite-dimensional Hopf algebras introduced and studied in the literature. In this note, we discuss compare their properties including invariance finiteness. Specifically, one notion is invariant under twisting taking Drinfeld double, exactly as other one. We also find that if non-cosemisimplicity dual Chevalley property hold, both exponents infinite characteri...

Investment risk models with infinite variance provide a better description of distributions of individual property returns in the Property Council of Australia data base from 1985 to 1996 than normally distributed risk models. The shape of the distribution of Australian property returns is virtually indistinguishable from the shape of United States property returns in the NCREIF Property Index ...

In this paper, we study Fractal Gene Regulatory Networks (FGRNs) evolved as local controllers for a modular robot in snake topology that reacts adaptively to environment. The task is to have the robot moving in a specific direction until it reaches a randomly placed targetzone and stays there. We point to a characteristic of FGRN model, namely “state-switching property” and demonstrate it as a ...

objective: endothelial progenitor cells (epcs) have a potential application for cell therapy, however, their biological nature is not well-understood. epcs also possess some stemness features, such as their clonogenicity and differentiation capacity. the main aim of this study was to evaluate the expression of certain transcription factors regulating self-renewal property of stem cells. materia...

This paper proposes fuzzy entropy minimization as an emergent property of holonic structures. When applied in the context of multi-agent systems this emergent property leads to automatic clustering of the agents into holonic organizations. When modeling enterprises as software agents the property turns into an inherent characteristic of holonic virtual organizations that enables clustering the ...

In order to forecast the stock market more accurately, according to the dynamic property for the stock market, propose the real time modeling forecast via dynamic recurrent neural network and use GA to study online, then it improves the network performance and better describes the dynamic characteristic of stock market. By forecasting Shanghai negotiable securities index, it shows better validi...
