It is known that a single stranded DNA molecule might produce a hairpin structure due to two biological principles, namely Watson-Crick complementarity and annealing. In many DNA-based algorithms, these DNA molecules cannot be used in the subsequent computations. Hairpin or hairpin-free DNA structures have numerous applications to DNA computing and molecular genetics. Suggested by the two afore...

We study finite automata running over infinite binary trees. A run of such an automaton is usually said to be accepting if all its branches are accepting. In this article, we relax the notion of accepting run by allowing a certain quantity of rejecting branches. More precisely we study the following criteria for a run to be accepting: (i) it contains at most finitely (resp. countably) many reje...

A number of eubacterial species contain methyl-accepting taxis proteins that are antigenically and thus structurally related to the well-characterized methyl-accepting chemotaxis proteins of Escherichia coli. Recent studies of the archaebacterium Halobacterium halobium have characterized methyl-accepting taxis proteins that in some ways resemble and in other ways differ from the analogous eubac...

modern manufacturing is under ever increasing pressure to develop solutions for highly complextasks. in order to maintain the business survival in a highly competitive environment, it is vital toobtain customer satisfaction, which requires developing products with shorter lifecycles and higherquality meanwhile to reduce the production costs. in order to achieve such objectives a paradigmhas bee...

evaluation of the advantages and weaknesses of principles oftransnational civil procedure, the joint work of the institute of americanlaw and the institute of unification of private law is the main subject ofthis article. the innovations of these principles such as the cooperationtheory, the distinction between the “principles” and the “rules”, thereasonable speed in addressing the case, provid...

The adoption of technology may be a necessary condition, but it is not sufficient for the digital transformation, seen as mobilizing challenge to do something new and different. Without strategic vision, we take risk acquiring resources same before, essentially changing format. This inability imprisons school inconsequential models, strategies. Interdisciplinary, social project-based learning t...
