Evolvable self-reproducing cells in a two-dimensional artificial chemistry.

We present a novel unit of evolution: a self-reproducing cell in a two-dimensional artificial chemistry. The cells have a strip of genetic material that is used to produce enzymes, each catalyzing a specific reaction that may affect the survival of the cell. The enzymes are kept inside the cell by a loop of membrane, thus ensuring that only the cell that produced them gets their benefit. A set of reaction rules, each simple and local, allows the cells to copy their genetic information and physically divide. The evolutionary possibilities of the cells are explored, and it is suggested that the system provides a useful framework for testing hypotheses about self-driven evolution.

    This research is an extension of the author's article \cite{zar}, in which conformally invariant generalization of string theory was suggested to higher-dimensional objects. Special cases of the proposed theory are Einstein's theory of gravity and string theory. This work is devoted to the formatio...

    We link optimal filtering for hidden Markov models to the notion of duality For Markov processes. We show that when the signal is dual to a process that Has two components, one deterministic and one a pure death process, and with Respect to functions that define changes of measure conjugate to the e...

    We investigate the simultaneous presence of both effects, i.e. a dual-frequency Plasma driven by two consecutive harmonics with different electrode materials. We find, that the superposition of the EAE and the SEAE is non-linear, i.e. the Asymmetries generated by each individual effect do not simply...
