Poezie Wilhelma Przeczka v českých a německých překladech
Authors: Martinek Libor 
Published: October 2020

In this article, we are presenting the work of a Polish poet from a Polish minority the Czech Cieszyn Silesia Wilhelm Przeczek (7. 4. 1936 v Karviná, Czechoslovakia - 10. 7. 2006 Třinec, Czech Republic) into the Czech and German language, as the author’s poetry was published not only in journals but also in books. We understand translation as an expression of intercultural communication, and especially in the area of the literature of a national minority, which is undoubtedly a Polish ethnic group in the Czech Cieszyn Silesia, it is a paramount phenomenon comparing the quality of literary life in the area with majority culture (Czech); as far as translations into German are concerned, it shows the interest of translators in the work of a poet from the Polish national minority, without this witnessing the emanation of a typical Polish soul in Polish literature in the Czech Republic and former Czechoslovakia, but it is evidence that it is fully competitive in total Polish national culture.
Pharmacokinetics and Pharmacodynamics Models of Tumor Growth and Anticancer Effects in Discrete Time
Authors: Atıcı Ferhan M. , Nguyen Ngoc , Dadashova Kamala , Pedersen Sarah E. , Koch Gilbert 
Published: October 2020

Abstract
We study the h-discrete and h-discrete fractional representation of a pharmacokinetics-pharmacodynamics (PK-PD) model describing tumor growth and anticancer effects in continuous time considering a time scale h𝕅0, where h > 0. Since the measurements of the drug concentration in plasma were taken hourly, we consider h = 1/24 and obtain the model in discrete time (i.e. hourly). We then continue with fractionalizing the h-discrete nabla operator in the h-discrete model to obtain the model as a system of nabla h-fractional difference equations. In order to solve the fractional h-discrete system analytically we state and prove some theorems in the theory of discrete fractional calculus. After estimating and getting confidence intervals of the model parameters, we compare residual squared sum values of the models in one table. Our study shows that the new introduced models provide fitting as good as the existing models in continuous time.
Special functions and Gauss–Thakur sums in higher rank and dimension
Authors: Gazda Quentin , Maurischat Andreas 
Published: October 2020

Abstract
Anderson generating functions have received a growing attention in function field arithmetic in the last years.
Despite their introduction by Anderson in the 1980s where they were at the heart of comparison isomorphisms, further important applications, e.g., to transcendence theory have only been discovered recently. The Anderson–Thakur special function interpolates L-values via Pellarin-type identities, and its values at algebraic elements recover Gauss–Thakur sums, as shown by Anglès and Pellarin.
For Drinfeld–Hayes modules, generalizations of Anderson generating functions have been introduced by Green–Papanikolas and – under the name of “special functions” – by Anglès, Ngo Dac and Tavares Ribeiro.
In this article, we provide a general construction of special functions attached to any Anderson A-module. We show direct links of the space of special functions to the period lattice, and to the Betti cohomology of the A-motive.
We also undertake the study of Gauss–Thakur sums for Anderson A-modules, and show that the result of Anglès–Pellarin relating values of the special functions to Gauss–Thakur sums holds in this generality.
3-Mercaptopyruvate sulfurtransferase: an enzyme at the crossroads of sulfane sulfur trafficking
Authors: Pedre Brandán , Dick Tobias P. 
Published: October 2020

Abstract
3-Mercaptopyruvate sulfurtransferase (MPST) catalyzes the desulfuration of 3-mercaptopyruvate to generate an enzyme-bound hydropersulfide. Subsequently, MPST transfers the persulfide’s outer sulfur atom to proteins or small molecule acceptors. MPST activity is known to be involved in hydrogen sulfide generation, tRNA thiolation, protein urmylation and cyanide detoxification. Tissue-specific changes in MPST expression correlate with ageing and the development of metabolic disease. Deletion and overexpression experiments suggest that MPST contributes to oxidative stress resistance, mitochondrial respiratory function and the regulation of fatty acid metabolism. However, the role and regulation of MPST in the larger physiological context remain to be understood.
Emerging roles for non-selenium containing ER-resident glutathione peroxidases in cell signaling and disease
Authors: Buday Katalin , Conrad Marcus 
Published: October 2020

Abstract
Maintenance of cellular redox control is pivotal for normal cellular functions and cell fate decisions including cell death. Among the key cellular redox systems in mammals, the glutathione peroxidase (GPX) family of proteins is the largest conferring multifaceted functions and affecting virtually all cellular processes. The endoplasmic reticulum (ER)-resident GPXs, designated as GPX7 and GPX8, are the most recently added members of this family of enzymes. Recent studies have provided exciting insights how both enzymes support critical processes of the ER including oxidative protein folding, maintenance of ER redox control by eliminating H2O2, and preventing palmitic acid-induced lipotoxicity. Consequently, numerous pathological conditions, such as neurodegeneration, cancer and metabolic diseases have been linked with altered GPX7 and GPX8 expression. Studies in mice have demonstrated that loss of GPX7 leads to increased differentiation of preadipocytes, increased tumorigenesis and shortened lifespan. By contrast, GPX8 deficiency in mice results in enhanced caspase-4/11 activation and increased endotoxic shock in colitis model. With the increasing recognition that both types of enzymes are dysregulated in various tumor entities in man, we deem a review of the emerging roles played by GPX7 and GPX8 in health and disease development timely and appropriate.

Phonetik und Phonologie in der DaF-Lehrerausbildung: ein Spannungsverhältnis zwischen universitären Lernzielen und dem Einsatz von DaF-Lehrwerken
Authors: Cruz Romão Tito Lívio , Costa Pereira Rogéria , dos Santos Nogueira Francisco G. 
Published: October 2020

Zusammenfassung
In Brasilien stellt der Phonetikunterricht in der DaF-Lehrerausbildung eine besondere Herausforderung dar. Da die meisten Studierenden auch DaF-Anfängerinnen bzw. -Anfänger sind, müssen sie simultan in die lautsprachliche Wahrnehmung und Produktion des Deutschen eingeführt und mit der phonetischen Transkription vertraut gemacht werden. Ziel dieses Beitrags ist es, im Hinblick auf das zu bewältigende Phonetikpensum den Einsatz von Lehrwerken für die universitäre DaF-Lehrerausbildung kritisch zu analysieren.

History of English as punctuated equilibria? A meta-analysis of the rate of linguistic change in Middle English
Authors: Nevalainen Terttu , Säily Tanja , Vartiainen Turo , Liimatta Aatu , Lijffijt Jefrey 
Published: October 2020

AbstractIn this paper, we explore the rate of language change in the history of English. Our main focus is on detecting periods of accelerated change in Middle English (1150–1500), but we also compare the Middle English data with the Early Modern period (1500–1700) in order to establish a longer diachrony for the pace at which English has changed over time. Our study is based on a meta-analysis of existing corpus research, which is made available through a new linguistic resource, the Language Change Database (LCD). By aggregating the rates of 44 individual changes, we provide a critical assessment of how well the theory of punctuated equilibria (Dixon, Robert M. W. 1997.The rise and fall of languages. Cambridge: Cambridge University Press) fits with our results. More specifically, by comparing the rate of language change with major language-external events, such as the Norman Conquest and the Black Death, we provide the first corpus-based meta-analysis of whether these events, which had significant societal consequences, also had an impact on the rate of language change. Our results indicate that major changes in the rate of linguistic change in the late medieval period could indeed be connected to the social and cultural after-effects of the Norman Conquest. We also make a methodological contribution to the field of English historical linguistics: by re-using data from existing research, linguists can start to ask new, fundamental questions about the ways in which language change progresses.
All-optical integrated 2-to-4 decoder and 1-to-4 demultiplexer circuit with enable using SOA based MZI
Authors: Nair Nivedita , Kaur Sanmukh , Singh Hardeep 
Published: October 2020

Abstract
In this paper, we propose an all-optical integrated 2-to-4 decoder and a 1-to-4 demultiplexer circuit using SOA based MZI (Mach–Zehnder Interferometer) architecture. The proposed device has been applied an enable signal along with two data input signals at the same wavelength. Four output signals from 2-to-4 decoder and 1-to-4 demultiplexer have been attained at the same wavelength. The output timing diagrams of 2-to-4 decoder and 1-to-4 demultiplexer for different input data conditions with clear eye opening patterns confirms the operation of the proposed logic device at 10 Gb/s. Maximum value of extinction ratio, contrast ratio and minimum value of amplitude modulation achieved for the different output waveforms are 12, 9.5 and 0.1 dB respectively. Easy integration with active and passive devices and simple architecture makes this device suitable for all-optical processing.
Assessing pragmatic competence in oral proficiency interviews at the C1 level with the new CEFR descriptors
Authors: Eizaga-Rebollar Bárbara , Heras-Ramírez Cristina 
Published: October 2020

Abstract
The study of pragmatic competence has gained increasing importance within second language assessment over the last three decades. However, its study in L2 language testing is still scarce. The aim of this paper is to research the extent to which pragmatic competence as defined by the Common European Framework of Reference for Languages (CEFR) has been accommodated in the task descriptions and rating scales of two of the most popular Oral Proficiency Interviews (OPIs) at a C1 level: Cambridge’s Certificate in Advanced English (CAE) and Trinity’s Integrated Skills in English (ISE) III. To carry out this research, OPI tests are first defined, highlighting their differences from L2 pragmatic tests. After pragmatic competence in the CEFR is examined, focusing on the updates in the new descriptors, CAE and ISE III formats, structure and task characteristics are compared, showing that, while the formats and some characteristics are found to differ, the structures and task types are comparable. Finally, we systematically analyse CEFR pragmatic competence in the task skills and rating scale descriptors of both OPIs. The findings show that the task descriptions incorporate mostly aspects of discourse and design competence. Additionally, we find that each OPI is seen to prioritise different aspects of pragmatic competence within their rating scale, with CAE focusing mostly on discourse competence and fluency, and ISE III on functional competence. Our study shows that the tests fail to fully accommodate all aspects of pragmatic competence in the task skills and rating scales, although the aspects they do incorporate follow the CEFR descriptors on pragmatic competence. It also reveals a mismatch between the task competences being tested and the rating scale. To conclude, some research lines are proposed.

Published: October 2020

Abstract
The occurrence of biofluorescence across Mammalia is an area of active study. We examined three specimens of the platypus (Ornithorhynchus anatinus) from Tasmania and New South Wales, Australia, housed in the Field Museum of Natural History (Chicago, Illinois, USA) and the University of Nebraska State Museum (Lincoln, Nebraska, USA) under visible light and ultraviolet (UV) light. The pelage of the animals appeared uniformly brown under visible light and green or cyan under UV light, due to fluoresced wavelengths that peaked around 500 nm. Our observations are the first report of biofluorescence in a monotreme mammal.
Macroscopic QED for quantum nanophotonics: emitter-centered modes as a minimal basis for multiemitter problems
Authors: Feist Johannes , Fernández-Domínguez Antonio I. , García-Vidal Francisco J. 
Published: October 2020

AbstractWe present an overview of the framework of macroscopic quantum electrodynamics from a quantum nanophotonics perspective. Particularly, we focus our attention on three aspects of the theory that are crucial for the description of quantum optical phenomena in nanophotonic structures. First, we review the light–matter interaction Hamiltonian itself, with special emphasis on its gauge independence and the minimal and multipolar coupling schemes. Second, we discuss the treatment of the external pumping of quantum optical systems by classical electromagnetic fields. Third, we introduce an exact, complete, and minimal basis for the field quantization in multiemitter configurations, which is based on the so-called emitter-centered modes. Finally, we illustrate this quantization approach in a particular hybrid metallodielectric geometry: two quantum emitters placed in the vicinity of a dimer of Ag nanospheres embedded in a SiN microdisk.
Exact solutions of bending deflection for single-walled BNNTs based on the classical Euler–Bernoulli beam theory
Authors: Yawei Dong , Yang Zhang , Jianwei Yan 
Published: October 2020

Abstract
At the nanolevel, a classical continuum approach seems to be inapplicable to evaluate the mechanical behaviors of materials. With the introduction of scale parameter, the scale effect can be reasonably described by the modified continuum theory. For boron nitride nanotubes (BNNTs), the scale effect can be reflected by the curvature and the dangling bonds at both ends, mainly the former for a slender tube. This study aims to achieve a good capability of classical Euler–Bernoulli theory to directly predict the bending behaviors of single-walled BNNTs without introducing scale parameters. Elastic properties of BNNTs involving the scale effect have been first conducted by using an atomistic-continuum multiscale approach, which is directly constructed based on the atomic force field. The well-determined hexagonal boron nitride sheet is inherited in the present study of single-walled BNNTs which can be viewed as rolling up a boron nitride sheet into a seamless hollow cylinder. Euler–Bernoulli theory solution of bending deflection on the basis of the present thickness is found to be much closer to the atomistic-continuum simulation results than the commonly used interlayer space. Case studies with different tubular lengths, radii and constraints are investigated, and from which the yielded scattered scale parameters in modified continuum theories are discussed.
Remarks on the Role of the Perfect Participle in Italian Morphology and on its History
Authors: Calabrese Andrea 
Published: October 2020

AbstractSince (Aronoff, Mark. 1994.Morphology by itself. Cambridge, MA: The MIT Press), the disparate morphosyntactic roles that past participle forms have in Latin (and Italian) morphology have played a central role in arguing for morphomic approaches. In this article, I will propose an alternative analysis of the special behavior of these participle forms in Distributed Morphology (DM, Halle Morris, & Alec Marantz. 1993. Distributed morphology and the pieces of inflection. In Kenneth Hale & Samuel Jay Keyser (eds.),The view from building 20: Essays in linguistics in honor of Sylvain Bromberger, 111–176. Cambridge, MA: MIT Press.). In particular, I will propose that morphological spell-out, as a first stage of the PF derivation, includes morphological repairs triggered by abstract “morphomic” constraints. These repairs can insert “ornamental” pieces – structures that are not motivated syntactically or semantically but only morphologically – to mediate the interface between abstract syntactico-semantic structures and surface PF construction. I will demonstrate the role that these repairs play in accounting for the surface convergence between perfect and passive participle forms, and adjectival stative ones, and for the appearance of past participles in nominalizations. The article ends with an analysis of Latin past participle morphology focusing on its historical development. The first part of this analysis deals with the development of Latin verbal structure from Proto-Indo-European (PIE) and in particular with the development of “ornamental” thematic vowels. It then turns to a brief investigation of the historical development of the Latin past participle exponent /-t-/ from PIE adjectival suffix*-tó-,and of the PIE agentive and action/result nominal suffixes*-tér/tor, *-ti-, *-tu, *-men-(to)-.This will lead to a discussion of Latin nominalizations, the supine and the future participle and a possible explanation of why they contain participial morphology.
Understanding (coupled) large amplitude motions: the interplay of microwave spectroscopy, spectral modeling, and quantum chemistry
Authors: Nguyen Ha Vinh Lam , Kleiner Isabelle 
Published: October 2020

Abstract
A large variety of molecules contain large amplitude motions (LAMs), inter alia internal rotation and inversion tunneling, resulting in tunneling splittings in their rotational spectrum. We will present the modern strategy to study LAMs using a combination of molecular jet Fourier transform microwave spectroscopy, spectral modeling, and quantum chemical calculations to characterize such systems by the analysis of their rotational spectra. This interplay is particularly successful in decoding complex spectra revealing LAMs and providing reference data for fundamental physics, astrochemistry, atmospheric/environmental chemistry and analytics, or fundamental researches in physical chemistry. Addressing experimental key aspects, a brief presentation on the two most popular types of state-of-the-art Fourier transform microwave spectrometer technology, i.e., pulsed supersonic jet expansion–based spectrometers employing narrow-band pulse or broad-band chirp excitation, will be given first. Secondly, the use of quantum chemistry as a supporting tool for rotational spectroscopy will be discussed with emphasis on conformational analysis. Several computer codes for fitting rotational spectra exhibiting fine structure arising from LAMs are discussed with their advantages and drawbacks. Furthermore, a number of examples will provide an overview on the wealth of information that can be drawn from the rotational spectra, leading to new insights into the molecular structure and dynamics. The focus will be on the interpretation of potential barriers and how LAMs can act as sensors within molecules to help us understand the molecular behavior in the laboratory and nature.
Generation of tailored subsurface zones in steels containing metastable austenite by adaptive machining and validation by eddy current testing
Authors: Fricke Lara Vivian , Nguyen Hai Nam , Breidenstein Bernd , Denkena Berend , Dittrich Marc-André , Maier Hans Jürgen , Zaremba David 
Published: October 2020

Abstract
In order to withstand high mechanical and tribological loads, it is important that the components not only have a high core ductility but also a hard surface. Typically, a suitable microstructure is created by heat treatment processes before the workpiece is machined. However, these processes are time and energy consuming and can lead to component distortion. It would therefore be of great advantage if no additional heat treatment process would be required to produce a hardened subsurface zone. Since turning is often already integrated as a machining process in production lines, it would be advantageous to create a hardened subsurface within this process. As there is no possibility to measure the hardness directly during the turning process, a soft sensor was developed to determine the properties of the subsurface directly during the machining process. Steels with metastable austenite are of particular interest in this context, as metastable austenite can be converted into martensite by deformation. The amount of martensite produced in the subsurface can be adjusted provided that suitable turning parameters can be found. For this purpose, a process parallel material removal simulation was used to determine the actual conditions governing the process. It was found that there is a correlation between the martensite content and the amplitude of the 3rd harmonic of eddy current testing. Therefore, an eddy current sensor accompanying the process can be used as a basis for controlling the turning process for tailored martensite volume content adjustment.
