Aperiodic Order and Singular Spectra
, 2022 This work focuses on several models of aperiodic order and their applications in different areas of mathematics and mathematical physics. After a short introduction to the theory of dynamicals systems, we present random substitutions as a stochastic variant of substitutions which create symbolic dynamical systems that combine long-range order with a ...

Topics in Cognitive Science, EarlyView., 2023 Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Aperiodic Weighted Automata and Weighted First-Order Logic
arXiv: Formal Languages and Automata Theory, 2019 By fundamental results of Sch tzenberger, McNaughton and Papert from the 1970s, the classes of first-order definable and aperiodic languages coincide. Here, we extend this equivalence to a quantitative setting. For this, weighted automata form a general and widely studied model. We define a suitable notion of a weighted first-order logic. Then we show

Advanced Functional Materials, EarlyView.Zinc‐air batteries demonstrate great potential for sustainable energy storage but face major anode‐related challenges. This review provides a mechanism‐driven overview of zinc anode interfacial issues, e.g. dendrite formation, passivation, self‐corrosion, and hydrogen evolution; and explores advances in electrode, surface, and electrolyte engineering ...

From the Fibonacci Icosagrid to E8 (Part II): The Composite Mapping of the Cores
CrystalsThis paper is part of a series that describes the Fibonacci icosagrid quasicrystal (FIG) and its relation to the E8 root lattice. The FIG was originally constructed to represent the intersection points of an icosahedrally symmetric collection of planar ...

Advanced Functional Materials, EarlyView.This work utilizes poly(heptazine imides) as a model system to demonstrate how fine‐tuning the crystal structure influences the photocatalytic properties of layered carbon nitrides in the hydrogen evolution reaction. In particular, the nature of rotational defects and the hydration shell of cations are key contributors to enhanced hydrogen evolution ...

Ramanujan sums for signal processing of low frequency noise
, 2002 An aperiodic (low frequency) spectrum may originate from the error term in the mean value of an arithmetical function such as M\"obius function or Mangoldt function, which are coding sequences for prime numbers.
