First-order properties of trees, star-free expressions, and aperiodicity [PDF]
RAIRO - Theoretical Informatics and Applications, 1991 It was shown by \textit{W. Thomas} [Trees in algebra and programming, 9th Coll., Bordeaux, France, 31-49 (1984; Zbl 0557.68051)] that for tree languages the notions of first-order definability, aperiodicity and star- freeness are not equivalent as they are in the case of regular word languages.

The Curled Up Dimension in Quasicrystals
Crystals, 2021 Most quasicrystals can be generated by the cut-and-project method from higher dimensional parent lattices. In doing so they lose the periodic order their parent lattice possess, replaced with aperiodic order, due to the irrationality of the projection ...

Group Theory of Syntactical Freedom in DNA Transcription and Genome Decoding
Current Issues in Molecular Biology, 2022 Transcription factors (TFs) are proteins that recognize specific DNA fragments in order to decode the genome and ensure its optimal functioning. TFs work at the local and global scales by specifying cell type, cell growth and death, cell migration ...

Broadband Mid-IR superabsorption with aperiodic polaritonic photonic crystals [PDF]
Journal of the European Optical Society-Rapid Publications, 2014 We propose an approach for broadband near-perfect absorption with aperiodic-polaritonic photonic crystals (PCs) operating in the phonon-polariton gap of the constituent material.

FO-definable transformations of infinite strings [PDF]
, 2016 The theory of regular and aperiodic transformations of finite strings has recently received a lot of interest. These classes can be equivalently defined using logic (Monadic second-order logic and first-order logic), two-way machines (regular two-way and
