Lattice of Substitutions
نویسنده
چکیده
Let us consider V , C. Observe that SubstitutionSet(V,C) is non empty. Let us consider V , C and let A, B be elements of SubstitutionSet(V,C). Then A∪B is an element of Fin(V→̇C). Let us consider V , C. One can check that there exists an element of SubstitutionSet(V,C) which is non empty. Let us consider V , C. One can verify that every element of SubstitutionSet(V,C) is finite. Let us consider V , C and let A be an element of Fin(V→̇C). The functor μA yielding an element of SubstitutionSet(V,C) is defined by:

The Incompleteness of the Lattice of Substitutions
In [12] we proved that the lattice of substitutions, as defined in [10], is a Heyting lattice (i.e. it is pseudo-complemented and it has the zero element). We show that the lattice needs not to be complete. Obviously, the example has to be infinite, namely we can take the set of natural numbers as variables and a singleton as a set of constants. The incompleteness has been shown for lattices of...

متن کاملRole of helix-helix interactions in assembly of the bacteriorhodopsin lattice.
The purple membrane of Halobacterium salinarium is a two-dimensional lattice of lipids and the integral membrane protein bacteriorhodopsin (BR). To determine whether helix-helix interactions within the membrane core stabilize this complex, we substituted amino acid residues at the helix-helix interface between BR monomers and examined the assembly of the protein into the lattice. Lattice assemb...
متن کاملMultidimensional Euclidean algorithms, numeration and substitutions
The aim of this survey is to discuss multidimensional continued fraction and Euclidean algorithms from the viewpoint of numeration systems, substitutions, and the symbolic dynamical systems they generate. We will mainly focus on two types of multidimensional algorithms, namely, unimodular Markovian ones which include the most classical ones like e.g. Jacobi-Perron algorithm, and algorithms issu...
متن کاملThe Effect of Coinage Transition Metal (Cu, Ag, Au) Substitutions on Two-electron Redox Potential of Quinones
Quinones are a class of compounds which have widespread importance in chemistry, biology and medicine. Because of their appropriate performance in electron transferring rate, quinones are among the most applicable mediators in biosensors. Recently, the effects of different non-metal substitutions on redox potential of quinone have been investigated to design suitable mediators for different ele...
متن کاملStructural insights into the effects of charge-reversal substitutions at the surface of horseradish peroxidase
Horseradish peroxidase (HRP), has gained significant interests in biotechnology, especially in biosensor field and diagnostic test kits. Hence, its solvent-exposed lysine residues 174, 232, and 241 have been frequently modified with the aim of improving its stability and catalytic efficiency. In this computational study, we investigated the effects of Lys-to-Glu substitutions on HRP structure t...
