A problem of self-referential paradox and self-reproduction is discussed in a network model of machines and tapes. A tape consists of a bit string, encoding function of a machine. Tapes are replicated when it is attached by an adequate machine. Generally, a tape is replicated but it may be di erent from the original one. In this paper, external noise evolves diversity in a system. New reaction ...

When Richard Drew of 3M developed creped paper masking tape in 1925, he began a revolutionary change in the way we live. From that first step, taking us from the over a century-old cloth backed pressure sensitive tape for surgical use to the many and varied industrial tapes which followed Richard Drew’s masking tape, it changed how we make things and how we do things. It is used in the manufact...

We define a model of advised computation by finite automata where the advice is provided on a separate tape. We consider several variants of the model where the advice is deterministic or randomized, the input tape head is allowed real-time, one-way, or two-way access, and the automaton is classical or quantum. We prove several separation results among these variants, demonstrate an infinite hi...

Depth profile analysis of a ferromagnetic layered sample composed of y-Fe203 and Cr02 tapes were performed with photothermally modulated ferromagnetic resonance (PMFMR). Those analysis were done by using phase-resolved and modulation frequency variation methods. The experiments showed the advantages of this technique over the conventional one. The dependency of the detected signal on the modula...

Low molecular weight gelators (LMWG) self-assemble in solution into one-dimensional objects such as fibres or tapes. The entanglement of these fibres or tapes results in the formation of a network and a gel. In general, LMWG are investigated as single component systems. However, there are significant potential opportunities from mixed LMWG systems, which are rarely investigated. Here, we discus...

In the title compound, C(4)H(6)N(3) (+)·C(6)HCl(2)O(4) (-)·H(2)O, anions, cations and water mol-ecules are linked by inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds into one-dimensional tapes along [111]. These tapes are further linked by weak Cl⋯Cl inter-actions [Cl⋯Cl = 3.394 (2) Å], forming sheets parallel to the (10) plane.

The title compound, 2C3H7N6 (+)·C6H7NO6 (2-)·3H2O, was obtained by mixing melamine and nitrilo-tri-acetic acid in aqueous solution. There is proton transfer from the nitrilo-triacteic acid to melamine to produce two melaminium cations and an inter-nal proton transfer to generate the [HN(CH2COO)](2-) zwitterion. The melaminium cations are arranged in hydrogen-bonded tapes formed by N-H⋯N inter-a...

This paper discusses how finite-state automata with multiple tapes can be used to construct decision procedures for fragments of first-order theories with interpreted functions and relations, useful in the verification of programs. There is a natural correspondence between automata accepting input on n > 1 tapes and predicates over n variables, but multi-tape automata that read input asynchrono...

The fabrication of nanowire (NW) devices on diverse substrates is necessary for applications such as flexible electronics, conformable sensors, and transparent solar cells. Although NWs have been fabricated on plastic and glass by lithographic methods, the choice of device substrates is severely limited by the lithographic process temperature and substrate properties. Here we report three new t...
