Self-Acting Intermittent Siphons

Experimenting with the acting self.

Recent neuroscientific research has developed the concept of the embodied agent as a scientifically viable approach to the psychological concept of the self. Both the awareness of one's own actions and awareness of one's own body are necessary conditions for the experience of selfhood. The relative contributions of efferent and afferent information in self-awareness are yet to be fully understo...

Nanoparticle - laden tubeless and open siphons †

Tubeless and open siphons operate without conduits, in the open, supported only by extensional stresses. Here, we demonstrate that the addition of silica nanoparticles in modest concentrations (on the order of 1% by weight) to an aqueous Poly(ethylene oxide) (PEO) solution of a moderately low concentration (0.5% by weight) has a dramatic effect on the power of the siphon as well as on the abili...

Siphons in chemical reaction networks.

Siphons in a chemical reaction system are subsets of the species that have the potential of being absent in a steady state. We present a characterization of minimal siphons in terms of primary decomposition of binomial ideals, we explore the underlying geometry, and we demonstrate the effective computation of siphons using computer algebra software. This leads to a new method for determining wh...

A Fast Method for Extracting all Minimal Siphons from Maximal Unmarked Siphons of a Petri Net

In this paper, a fast method named algorithm 2 is proposed to extract all minimal siphons from maximal unmarked siphons obtained by the MIP-based deadlock detection method. Redundant computation is the major disadvantage of an existing method named algorithm 1 and it greatly decreases the computational efficiency of minimal siphons. In order to resolve this problem, the proposed method improves...
