Composition inverses of the variations of the Baum-Sweet sequence

Studying and comparing arithmetic properties of a given automatic sequence and the sequence of coefficients of the composition inverse of the associated formal power series (the formal inverse of that sequence) is an interesting problem. This problem was studied before for the Thue-Morse sequence. In this paper, we study arithmetic properties of the formal inverses of two sequences closely related to the well-known Baum-Sweet sequence. We give the recurrence relations for their formal inverses and we determine whether the sequences of indices at which these formal inverses take value $0$ and $1$ are regular. We also show an unexpected connection between one of the obtained sequences and the formal inverse of the Thue-Morse sequence.Comment: 25 page

Formal inverses of the generalized Thue-Morse sequences and variations of the Rudin-Shapiro sequence

A formal inverse of a given automatic sequence (the sequence of coefficients of the composition inverse of its associated formal power series) is also automatic. The comparison of properties of the original sequence and its formal inverse is an interesting problem. Such an analysis has been done before for the Thue{Morse sequence. In this paper, we describe arithmetic properties of formal inverses of the generalized Thue-Morse sequences and formal inverses of two modifications of the Rudin{Shapiro sequence. In each case, we give the recurrence relations and the automaton, then we analyze the lengths of strings of consecutive identical letters as well as the frequencies of letters. We also compare the obtained results with the original sequences.Comment: 20 page

Old Germplasm for New Needs

The impacts of climate change on crop production are already a reality in Europe and across the rest of the world. In order to mitigate these impacts, access to unexploited genetic crop diversity for the production of new varieties that can thrive in more extreme environmental conditions is of prime importance. Herein, genetic diversity should provide the raw materials for breeding and plant improvements. Despite the vast pool of resources that exist, much of the germplasm richness found in gene banks is poorly documented. To overcome the barriers between germplasm conservation and use, a complete evaluation is necessary to determine the useful diversity they contain.This Special Issue focuses on “Old Germplasm for New Needs: Managing Crop Genetic Resources”. We gathered novel research, reviews, and opinion pieces covering all related topics, including germplasm evaluation, crop genetics and improvements, novel crops, phenotyping, physiological responses of inbred lines, management solutions, modeling, case studies from the field, and policy positions

Personal Knowledge Models with Semantic Technologies

Conceptual Data Structures (CDS) is a unified meta-model for representing knowledge cues in varying degrees of granularity, structuredness, and formality. CDS consists of: (1) A simple, expressive data-model; (2) A relation ontology which unifies the relations found in cognitive models of personal knowledge management tools, e. g., documents, mind-maps, hypertext, or semantic wikis. (3) An interchange format for structured text. Implemented prototypes have been evaluated

Schubert's mature operas: an analytical study

This thesis examines four of Franz Schubert's complete operas: Die Zwillingsbrűder D.647, Alfonso und Estrella D.732, Die Verschworenen D.787, and Fierrabras D.796. These works date from the period of 1818-1823, sometimes referred to as Schubert's 'years of crisis'. While this period saw many changes in the composer's personal situation, it is commonly thought that he underwent a process of creative re-evaluation during these years. This was also the period of Schubert's life during which he was most seriously engaged in writing music for the stage. Thus, I argue in this thesis that it is possible to understand these operas as key works within Schubert's stylistic development. Chapter 2 of this thesis studies Adorno's 1928 critique of Schubert and draws out common themes in critical writings about the composer to do with coherence, temporality and tone. These themes are then grounded in various different types of analytical observations about Schubert's emergent style. Chapter 3 examines selected numbers from the four mature operas. Through analysing these works, we find that Schubert's developing approach to form, rhythm, musical 'signs' and other structural devices is evident. Innovations in each of these fields are understood as responses to the various dramatic challenges offered by each of the libretti. Chapter 4 summarises the conclusions of our study of the operas and suggests some possibilities for interpretation of other works which are raised by these analyses
