Supporting Information: Spatiotemporally programmable metasurfaces via viscoelastic shell snapping

Supplementary Text 1: Material modeling and characterization We used the following incompressible neo-Hookean material model to define the instantaneous constitutive behavior of the shells, = tr − 3, (S1) where W is the strain energy density function, µ is the shear modulus, F is the deformation gradient tensor. To describe the viscoelastic behavior of the shells, Prony series were used and the shear modulus µ can be expressed as = 1 − ∑ 1 − ⁄ , (S2) where µ0 is the instantaneous shear modulus, n is the number of the series terms, is the dimensionless relaxation modulus, t is the time, and τi is the relaxation time constant. Here we characterize the viscoelastic properties of the silicone rubber (Dragon SkinTM30) and urethane rubber (VytaFlexTM 20). We modeled their viscou

«One, Two - Trees...»: Counting-out Rhymes in the Teaching of Ukrainian Language to Foreign Students

The article is devoted to the research of linguodidactic potential of counting-out rhymes in classes of Ukrainian as a foreign language. Now there are many works in Ukrainian methodology of teaching language to foreign students concerning the formation of a set of texts for studying purposes. The authors of selected scientific articles suggest including folklore texts (fairy tales, songs, legends, proverbs and sayings, tongue twisters) in the teaching of the Ukrainian language. The aim of our article is to explore the place and role of the counting-out rhyme as a supplementary text for foreign students of beginner level. For this purpose, we describe the definition of the term «counting-out rhyme», define the linguistic and methodological criteria for selecting texts and how they should be presented to foreign audiences. Results of the research. The counting-out rhyme is a genre of children's playful folklore, a small-form poetic text with a clear rhyme-rhythmic structure. For to study Ukrainian as a foreign language at the beginning stage not all the texts of counting-out rhymes are suitable, but only those that folklorist G. Vinogradov called «chislovka» or «proper chislovka". This type of counting-out rhymes have cardinal numbers and ordinal numbers as a part of their structure. We consider that the main criteria for selecting and presenting texts of this genre as educational units should be: 1) a simple structure, clear and understandable content of the text; 2) the common vocabulary of counting-out rhymes, which corresponds as much as possible to communicative topics and grammatical material of the beginner level of Ukrainian language learning; 3) the texts of the counting rhymes should be chosen with the aim of practising certain speech skills and abilities; 4) limited amount of the material. In classes with foreign students, we primarily use counting-out rhymes to introduce the category of numerals and to teach counting. Children's folklore play texts act as very important supplementary linguistic material. Rational, accurate counting (mostly from one to ten) and the rhythm and rhythmics of the short poetic text help a foreign student to learn to count in Ukrainian quickly and easily. In addition, the expressive reading of counting-out rhymes helps to improve the phonetic aspect of foreign language speech - clear pronunciation of separate sounds, intonation, accents, training of rhythm, speed of speech. Working with the texts of counting-out rhymes in UFL classes also actualises word meanings within the boundaries of communicative topics of the first year of language learning, enriches vocabulary, and optimises the rapid memorisation of typical lexical-grammatical constructions with their subsequent inclusion in the active vocabulary. Moreover, tasks with counting-out rhymes engage an element of a game in the learning process, making the lesson more exciting and interesting. Conclusions. The results of the analysis show that the counting-out rhymes have linguodidactic potential and can be used as supplementary teaching material in UFL classes (beginner level).

Peritext of the Russian translation of William Hogarth’s Analysis of Beauty: a case study

Translation of philosophical texts is a special challenge because of specific philosophical idiom and conceptual complexity of the narrative. It is not surprising that such translations are often accompanied by commentaries where the translator steps out of the shadows to justi­fy the translational decisions. This kind of supplementary text called the “translational peritext” is under study in this paper aiming to reveal the cognitive effort the translation process involves, and to explore the author-translator-reader relationship. The purpose of the article is to analyze paratextual elements in the translation of an essay on philosophical aes­thetics in search of answers to three main questions: What does the translator choose to com­ment on, and why? What is specific about the role and function of translational peritext in philosophical artistic discourse? How do the commented translational decisions affect, if at all, the reader’s understanding of the author’s stance? The problem of revealing the translator’s agency, his/her motivations and decision-making is investigated on the basis of the essay Analysis of Beauty by the celebrated 18th century English artist William Hogarth — an in­fluential philosophical treatise whose ideas have never lost their relevance. The paper starts with the brief account of the concept of paratext, its types and functions; it will then proceed to specificities of philosophical translation. In the main part of the article, the background information on the material under study precedes the analysis of the identified commented translational issues.

Improved representation of sequence Bloom trees

Motivation Algorithmic solutions to index and search biological databases are a fundamental part of bioinformatics, providing underlying components to many end-user tools. Inexpensive next generation sequencing has filled publicly available databases such as the Sequence Read Archive beyond the capacity of traditional indexing methods. Recently, the Sequence Bloom Tree (SBT) and its derivatives were proposed as a way to efficiently index such data for queries about transcript presence. Results We build on the SBT framework to construct the HowDe-SBT data structure, which uses a novel partitioning of information to reduce the construction and query time as well as the size of the index. Compared to previous SBT methods on real RNA-seq data, HowDe-SBT can construct the index in less than 36% of the time, and with 39% less space, and can answer small-batch queries at least five times faster. We also develop a theoretical framework in which we can analyze and bound the space and query performance of HowDe-SBT compared to other SBT methods. Availability and implementation HowDe-SBT is available as a free open source program on https://github.com/medvedevgroup/HowDeSBT.

Carl Czerny's Mechanical Reproductions

This article reassesses the “mechanical” style of playing featured in Carl Czerny's pedagogical works and keyboard arrangements—specifically, the Complete Theoretical and Practical Piano Forte School, op. 500 (1839), its supplementary text Letters to a Young Lady (ca. 1840), and the four-hand transcription of Beethoven's Symphony no. 9 in D Minor, op. 125 (the “Choral”). The first part of the article situates opus 500 within the larger pedagogical milieu of Biedermeier music culture and Johann Heinrich Pestalozzi's progressivist educational reforms, exploring the way it tasked predominantly women amateurs with assembling basic finger sensations in an exercise-by-exercise—“progressive”—fashion. I propose that this cumulative logic reflects an early-century epistemic norm—what Friedrich Kittler dubs a “mechanical program” of assembly and augmentation. The second part considers Czerny's transcription of the finale of Beethoven's Ninth from the perspective of ludo-musicology and cultural techniques media analysis, outlining the reductive and replicative—“reproductive”—techniques by which Czerny accommodated his former teacher's work to the hands he shaped in the private sphere. I argue that his pedagogies and transcriptions were recursively interrelated. Czerny was simultaneously a mechanic of the hand pedagogically and a mechanical reproducer of symphonies transcriptively, creating a multivalent corpus that forces us to rethink the media-theoretical concept of “mechanical reproduction” vis-à-vis “Discourse Network 1800.”

Landscape of gene transposition-duplication within the Brassicaceae family

ABSTRACTWe developed the CLfinder-OrthNet pipeline that detects co-linearity in gene arrangement among multiple closely related genomes; find ortholog groups; and encodes the evolutionary history of each ortholog group into a representative network (OrthNet). Using a search based on network topology, out of a total of 17,432 OrthNets in six Brassicaceae genomes, we identified 1,394 that included gene transposition-duplication (tr-d) events in one or more genomes. Occurrences of tr-d shared by subsets of Brassicaceae genomes mirrored the divergence times between the genomes and their repeat contents. The majority of tr-d events resulted in truncated open reading frames (ORFs) in the duplicated loci. However, the duplicates with complete ORFs were significantly more frequent than expected from random events. They also had a higher chance of being expressed and derived from older tr-d events. We also found an enrichment, compared to random chance, of tr-d events with complete loss of intergenic sequence conservation between the original and duplicated loci. Finally, we identified tr-d events uniquely found in two extremophytes among the six Brassicaceae genomes, including tr-d of SALT TOLERANCE 32 and ZINC TRANSPORTER 3. The CLfinder-OrthNet pipeline provides a flexible and a modular toolkit to compare gene order, encode and visualize evolutionary paths among orthologs as networks, and identify all gene loci that share the same evolutionary history using network topology searches.Funding source: This work was supported by National Science Foundation (MCB 1616827) and the Next Generation BioGreen21 Program (PJ011379) of the Rural Development Administration, Republic of Korea.Online-only Supplementary materials includes supplementary text (S1-S10), methods (M1-M4), figures (S1-S7), and tables (S1-S3), in two PDF files, one for text and methods and the other for figures and tables.
