Methyl-accepting chemotaxis proteins are central to both the excitation and adaptation phases of chemotactic behavior. Using null mutations in the genes coding for the two major methyl-accepting proteins (tsr and tar), we identified the gene products among the membrane proteins of Escherichia coli visualized on one- and two-dimensional gels. On two-dimensional gels, both the tsr and the tar pro...
Mouse DNA methyltransferase is able to catalyse the transfer of a methyl group to certain CG-containing single-stranded oligonucleotides. The presence of a methylcytosine is required for efficient transfer. This methylcytosine may or may not be on the same oligonucleotide as that containing the accepting CG dinucleotide. When the accepting CG dinucleotide forms part of an unmethylated CG dinucl...
This paper introduces a three-dimensional synchronized alternating Turing machine (3-SATM), and investigates fundamental properties of 3-SATM ′s whose input tapes are restricted to cubic ones. The main topics of this paper are: (1) a relationship between the accepting powers of 3-SATM ′s and three-dimensional alternating Turing machines with small space bounds, (2) a relationship between the ac...
Humans report perceptions of unease or eeriness as humanoid/android robots and digital avatars approach human-like physical resemblance, a phenomenon alluded by the Uncanny Valley theory. This study extends discussions on interactions acceptance with findings from three experiments. In first, perceptive evaluation actors in clips computer-generated animation live-action version same movie was e...
In this paper, we study the concept of accepting grammars within various forms of regulated grammars like programmed grammars, matrix (set) grammars, grammars with regular (set) control, periodically time-variant grammars as variants of grammars controlled by bi-coloured digraphs. We focus on their descriptive capacity. In this way, we continue our studies of accepting grammars 1, 2, 3, 11, 13,...
A condition characterizing the class of regular languages which have several nonisomorphic minimal reversible automata is presented. The condition concerns the structure of the minimum automaton accepting the language under consideration. It is also observed that there exist reduced reversible automata which are not minimal, in the sense that all the automata obtained by merging some of their e...
The dissimilatory Fe(III) reducer Geobacter metallireducens reduced Fe(III) bound in humic substances, but the concentrations of Fe(III) in a wide range of highly purified humic substances were too low to account for a significant portion of the electron-accepting capacities of the humic substances. Furthermore, once reduced, the iron in humic substances could not transfer electrons to Fe(III) ...
