Chaotic strings are a class of non-hyperbolic coupled map lattices, exhibiting a rich structure of complex dynamical phenomena with a surprising correspondence to physical contents. In this paper we introduce different types and models for chaotic strings, where 2B-strings with finite length are considered in detail. We demonstrate possibilities to extract renormalized quantities, which are expected to describe essential properties of the string.
AbstractIn this paper, the authors analyse the ambiguous political decision to ban the major Russian web resources from access to the Ukrainian market, in spite of heavy criticisms from local and foreign experts. While the supporters of the new internet policy claimed the new strategy to be coherent with cybersecurity priorities of the country, the opponents pointed out a set of legal and political limitations. Drawing on the setting and results of taking a new approach to information policy, we describe the fragility of Euromaidan democratic heritage and drawbacks of the current political regime. The logical method of legal interpretation has been applied to analyse the controversies of the current legislation on Russian internet resources restriction. The article concludes that Ukrainian post-Euromaidan governance model needs to consolidate the efforts in order to prove the commitment to freedom of speech as a core European value and replace spontaneous actions with an evidence-based approach to political decision-making.
This article surveys the official narrative on representation of Estonian identity and Estonianness through the tourism strategy implemented by Estonia from 2007 to 2015. Gathering material from brochures and documents targeting foreigners produced by the Estonian Institute and “Enterprise Estonia” (EAS) and analyzing the logic behind the interior design of Tallinn Airport, we engage with current debates on identity construction in post-Soviet spaces. In particular, we suggest that along with an established body of literature looking at the role of state actors in the construction of identity, studies should consider the role of nontraditional or non-state actors in identifying and promoting identity markers.

Names in programming are vital for understanding the meaning of code and big data. We define code2brain (C2B) interfaces as maps in compilers and brains between meaning and naming syntax, which help to understand executable code. While working toward an Evolvix syntax for general‐purpose programming that makes accurate modeling easy for biologists, we observed how names affect C2B quality. To protect learning and coding investments, C2B interfaces require long‐term backward compatibility and semantic reproducibility (accurate reproduction of computational meaning from coder‐brains to reader‐brains by code alone). Semantic reproducibility is often assumed until confusing synonyms degrade modeling in biology to deciphering exercises. We highlight empirical naming priorities from diverse individuals and roles of names in different modes of computing to show how naming easily becomes impossibly difficult. We present the Evolvix BEST (Brief, Explicit, Summarizing, Technical) Names concept for reducing naming priority conflicts, test it on a real challenge by naming subfolders for the Project Organization Stabilizing Tool system, and provide naming questionnaires designed to facilitate C2B debugging by improving names used as keywords in a stabilizing programming language. Our experiences inspired us to develop Evolvix using a flipped programming language design approach with some unexpected features and BEST Names at its core.
In Treatise 22.214.171.124 Hume provides an explanation of why ‘we naturally desire what is forbid, and take a pleasure in performing actions, merely because they are unlawful’. Hume's explanation of this phenomenon has barely received any attention so far. But a detailed analysis bears fruit for both Humean scholarship and contemporary moral psychology. After putting the passage in its context, I explain why desiring and taking pleasure in performing certain actions merely because they are unlawful poses a challenge to Hume's theory of evaluation. Then I propose a solution of the challenge which draws on Hume's treatment of malice, and highlights the role played by comparison and the self in these apparently paradoxical passions. Finally, I distinguish three views in contemporary discussions of desiring something under the guise of the bad (negationism, parasitism, at-face-valuism), and I argue that Hume's account stands out as a particularly plausible version of the third view.
The multisine excitation is widely used in impedance measurements to retain the advantages of the sine wave, while reducing the measurement time. Adding up sine waves increases the amplitude of the excitation signal, but, for the linearity assumption to be valid, the overall amplitude of the signal needs to be kept low. Thus, the crest factor (CF) of the excitation signal must be minimized. A novel empirical method for minimization of the CF is presented in this paper. As in case of other known methods, the computed CF may be guaranteed to be only a local minimum. However, a systematic variation of initial parameters, which is possible due to the sparing algorithm, ensures the CF value, very close or equal to the global minimum. A brief analysis of the calculation errors and comparison with the results from other sources is provided. In the DSP applications, initial phases of the waveforms must match the grid of sample points if separate signal sources are used to generate the components. An equation for calculation of the indexes of the sample points corresponding to the optimal initial phases is provided, and the time discreteness caused relative error of CF is illustrated.

The introduction of pottery vessels to Europe has long been seen as closely linked with the spread of agriculture and pastoralism from the Near East. The adoption of pottery technology by hunter–gatherers in Northern and Eastern Europe does not fit this paradigm, and its role within these communities is so far unresolved. To investigate the motivations for hunter–gatherer pottery use, here, we present the systematic analysis of the contents of 528 early vessels from the Baltic Sea region, mostly dating to the late 6th–5th millennium cal BC, using molecular and isotopic characterization techniques. The results demonstrate clear sub-regional trends in the use of ceramics by hunter–gatherers; aquatic resources in the Eastern Baltic, non-ruminant animal fats in the Southeastern Baltic, and a more variable use, including ruminant animal products, in the Western Baltic, potentially including dairy. We found surprisingly little evidence for the use of ceramics for non-culinary activities, such as the production of resins. We attribute the emergence of these sub-regional cuisines to the diffusion of new culinary ideas afforded by the adoption of pottery, e.g. cooking and combining foods, but culturally contextualized and influenced by traditional practices.
