O DINAMISMO ECONÔMICO E PRODUTIVO DO ESTADO DE MATO GROSSO DO SUL PÓS-2003: AS TRANSFORMAÇÕES PRODUTIVAS DAS MESORREGIÕES
Authors: Farias Fernando Rodrigo , Espíndola Carlos José , Cunha Roberto César 
Published: February 2021

O Estado do Mato Grosso do Sul apresentou, a partir de 2003, um crescimento econômico médio na ordem de 9,5% ao ano. O Produto Interno Bruto, em 2003, somou R$ 21,8 bilhões e, em 2017, saltou para R$ 96,3 bilhões. O setor de exportações, apesar dos períodos de flutuações econômicas, teve crescimento expressivo no período analisado. Em 2003, o volume das receitas das exportações somou R$ 497,9 milhões e, em 2019, atingiu R$ 5,2 bilhões. Diante disso, surge a questão central: quais os fatores geoeconômicos endógenos e exógenos que contribuíram para a ocorrências dessas transformações? Nesse sentido, o artigo visa demonstrar as recentes alterações na dinâmica produtiva no estado do Mato Grosso do Sul pós-2003 e suas combinações geoeconômicas propulsoras. Metodologicamente, partiu-se de uma revisão bibliográfica acompanhada de coletas de dados nos órgãos oficiais e visando identificar as alterações na dinâmica produtiva no estado. As transformações e o reordenamento regional da matriz produtiva aconteceram de maneira concentrada em número reduzido de municípios em forma de “ilhas de desenvolvimento” nas mesorregiões. Isso ocorreu devido à estreita relação entre os investimentos estatais em setores estratégicos ligados ao movimento da economia nacional e a dinâmica do mercado externo.

Abstract.
Given a Carnot–Carathéodory space with associated frame of vector fields , we derive the subelliptic ∞-Laplace system for mappings , which reads

in the limit of the subelliptic p-Laplacian as . Here is the horizontal gradient and is the projection on its nullspace. Next, we identify the variational principle characterizing the subelliptic ∞-Laplacian system, which is the “Euler–Lagrange PDE” of the supremal functional

for an appropriately defined notion of horizontally ∞-minimal mappings. We also establish a maximum principle for for solutions to the subelliptic ∞-Laplacian system. These results extend previous work of the author [J. Differential Equations 253 (2012), no. 7, 2123–2139; Proc. Amer. Math. Soc., to appear] on vector-valued calculus of variations in L
∞ from the Euclidean to the subelliptic setting.

Published: February 2021

Zusammenfassung
In einer Produktionsumgebung beeinflussen mechanische Vibrationen den Relativabstand zwischen Inspektionsgerät und Werkstück, was für
Messungen im Nanometerbereich hinderlich ist. Dieser Beitrag stellt eine Metrologieplattform zur Montage eines Inspektionsgerätes vor,
die mittels eines H∞-Reglers den Relativabstand zum Werkstück konstant hält. Ein Laboraufbau mit einem Freiheitsgrad zeigt,
dass in der Produktionsumgebung vorkommende Vibrationen um eine Größenordnung reduziert werden können, was eine
Oberflächencharakterisierung im Nanometerbereich direkt in der Produktion ermöglicht.
Extremum seeking dead-zone pre-compensator for an industrial control system
Authors: Dincmen Erkin 
Published: February 2021

Abstract
PID type industrial controllers such as PI, PD, PID are mature control algorithms and they are intensively used in
industry due to their simplicity and easily implementability. However, they start to fail when there is an unknown or
unpredictable nonlinear behavior in the plant or actuator. In this paper, a novel compensation algorithm is proposed for
PD type industrial control systems, which possess an unknown dead-zone nonlinearity. An extremum-seeking technique is
utilized in the compensation algorithm. The aim is to propose a new, effective and robust compensator which can be added
easily to an existing industrial controller without any need to change/retune the controller settings/parameters. It is
shown that by adding the compensator to an existing PD control system, the sensitivity of the controller to the dead-zone
nonlinearity is removed.
Structural Analysis of the Lactoferrin Iron Binding Pockets
Authors: Marchewka Damian , Roterman Irena , Strus Magdalena , Śpiewak Klaudyna , Majka Grzegorz 
Published: February 2021

ABSTRACT
Lactoferrin (Lf) - member of the transferrin family of proteins responsible for many different functions in the body of mammals participates in regulation of free iron level in the body fluids making the protein bacteriostatic.
The main goal of studies was to test the suitability of molecular dynamic simulation to study structural changes in the tertiary structure of lactoferrin.
According to ConSurf Server analysis one of the most conservative amino acids was found not only in iron- but also in carbohydrates- binding pockets which may suggest a significant impact of carbohydrates on the functions performed by lactoferrin. Pocket-Finder program applied to find iron-binding pockets revealed the potential Fe binding area. The stability of the ligand deprived protein was verified performing the 50 ns dynamic simulation using the Gromacs program. The tertiary structure changes during the simulation were observed in N-lob solely. No structural changes were observed in C-lob iron-binding pocket.
Assessing the impacts of nonindigenous marine macroalgae: an update of current knowledge
Authors: Davidson Alisha D. , Campbell Marnie L. , Hewitt Chad L. , Schaffelke Britta 
Published: February 2021

Abstract
Nonindigenous marine species continue to be one of the foremost threats to marine biodiversity. As an update to a 2007 review of the impacts of introduced macroalgae, we assessed 142 additional publications to describe species’ impacts as well as to appraise information on the mechanisms of impact. Only 10% of the currently known nonindigenous macroalgal species were subjects of ecological impact studies, with changed community composition as the most commonly reported effect. Economic impacts were rarely published. Recent research has focused on the impacts of introduced macroalgal assemblages: red algal introductions to the Hawaiian Islands and turf algae in the Mediterranean. Several general issues were apparent. First, many publications included nonsignificant results of statistical analyses but did not report associated power. As many of the studies also had low effect and sample size, the potential for type II errors is considerable. Second, there was no widely accepted framework to categorize and compare impacts between studies. Information in this updated review was still too sparse to identify general patterns and mechanisms of impact. This is a critical knowledge gap as rates of introductions and hence impacts of nonindigenous macroalgae are expected to accelerate with climate change and increasing global trade connectivity.
The Gezi Resistance and activist citizen reporters
Authors: Çoban Barış , Ataman Bora 
Published: February 2021

Abstract
This study discusses how activist citizen reporters in Turkey, who initiated a brand-new alternative new media practice,
transformed news gathering and writing activities in the process of the Gezi Park Resistance, which erupted in Istanbul in
June 2013. A handful of citizens, outraged by the police violence as well as interested in human rights from a journalistic
perspective chose to create their own make-shift media outlets or to become medium themselves. They gathered and simultaneously
disseminated news and broadcast live on many occasions mostly through social media platforms such as Twitter, Facebook and
livestream, in the absence of traditional mainstream and/or alternative media. They also contributed to the solidarity of the resistance.
In this context, the theoretical framework of this study is based on concepts such as alternative media, citizen media and citizen
journalism. Likewise, concepts like democracy, citizen and journalism are also re-evaluated from a radical perspective. After theorizing
‘Çapulcu Media’, a local variant of the Rodriguez’s ‘citizen media’, constructed in the Gezi Resistance by a few activist citizen reporters,
this ethnographic study concentrates on their activities in the field as well as the process of their identity formation based on data
collected from in-depth interviews and continuous attention given to their social media accounts. Finally, this study aims to develop
a critical understanding of a radical variant of citizen journalism in the context of contemporary Occupy movements.
Extensions of Cantor minimal systems and dimension groups
Authors: Glasner Eli , Host Bernard 
Published: February 2021

Abstract.

Given a factor map of Cantor minimal systems, we study the relations between the dimension groups of the two systems. First, we interpret the torsion subgroup of the quotient of the dimension groups
in terms of intermediate extensions which are extensions of
(Y,S) by a compact abelian group. Then we show that, by contrast, the existence of an intermediate non-abelian
finite group extension can produce a situation where the dimension group of
(Y,S) embeds into a proper subgroup of the dimension group of (X,T),
yet the quotient of the dimension groups is nonetheless torsion free. Next we define higher order cohomology groups
associated to an extension, and study them in various cases (proximal extensions, extensions by,
not necessarily abelian, finite groups, etc.). Our main result here is that all the cohomology groups
are torsion groups. As a consequence we can now identify
as the torsion group of the quotient group .
Tilting modules over tame hereditary algebras
Authors: Angeleri Hügel Lidia , Sánchez Javier 
Published: February 2021

Abstract.

We give a complete classification of the infinite dimensional tilting modules over a tame hereditary algebra R.
We start our investigations by considering
tilting modules of the form where is a union of tubes, and denotes the universal localization of R at in the sense of Schofield and Crawley-Boevey. Here is a direct sum of the Prüfer modules corresponding to the tubes in . Over the Kronecker algebra, large tilting modules are of this form in all but one case, the exception being the Lukas tilting module L whose tilting class consists of all modules without indecomposable preprojective summands. Over an arbitrary tame hereditary algebra, T can have finite dimensional summands, but the infinite dimensional part of T is still built up from universal localizations, Prüfer modules and (localizations of) the Lukas tilting module. We also recover the classification of the infinite dimensional cotilting R-modules due to Buan and Krause.
On reduced Beltrami equations and linear families of quasiregular mappings
Authors: Jääskeläinen Jarmo 
Published: February 2021

Abstract.

This paper studies linear classes of planar quasiregular mappings. We give a positive answer to a conjecture of K. Astala, T. Iwaniec, and G. Martin (2009) on reduced Beltrami equations. Moreover, we use it to prove a Wronsky-type theorem for general linear Beltrami systems. This is a key to show that the associated Beltrami equation of a linear quasiregular family is unique.

Epitaxial Growth and Multiferroic Properties of (001)-Oriented BiFeO3-YMnO3 Films
Authors: Nie Peng-Xiao , Wang Yi-Ping , Yang Ying , Yuan Guo-Liang , Li Wei , Ren Xue-Ting 
Published: February 2021

Abstract
In this paper, high-quality multiferroic (1-x)BiFeO3-xYMnO3 (x=0.05, 0.10, 0.15) thin films were successfully epitaxially grown on (001)SrTiO3 substrates with La0.67Sr0.33MnO3 buffered layers by pulsed laser deposition (PLD). X-ray diffraction shows the thin films are all single-phase perovskite with preferential orientation along the (001) direction. The (002) diffraction angles of thin films (from 0 to 0.15) shift to right, indicating the decrease of lattice parameters. All YMnO3-doped thin films exhibit strong upward self-poling via piezoelectric force microscope (PFM) measurement. Saturated ferroelectric hysteresis loops of thin films cannot be obtained even at the frequency of 50 kHz because of large leakage currents. It is noted that BFO-YMO thin films exhibit ferroelectricity considering the PFM and ferroelectric test. The magnetization measurements show that all BiFeO3-based films exhibit weak ferromagnetic behaviors with saturated magnetization at room temperature. The enhancement of magnetization was observed because of YMO doping, with the maximum saturation magnetization (M
s) of 17.07 emu/cm3 in x=0.10 thin film.
Omkring Johannes V. Jensens himmerlandshistorie ”Wombwell”
Authors: Jørgensen Aage 
Published: February 2021

Abstract
This article discusses one of Johannes V. Jensens ”Himmerland Sto­ries”, ”Wombwell”, which appeared in Nye Himmerlandshistorier in 1904, as well as some related texts. ”Wombwell” may be said to illustrate how the tradition-bound inhabitants of rural Himmerland experienced the hurried, violent modern world passing by in the shape of the well-known, world-famous English menagerie established in 1805 by George Wombwell, whose successors as a matter of fact toured in Northern Jutland in the summer of 1888. A major issue raised in the text is a longing Wombwell’s magnificent appearance inspires in the minds of three local youngsters, now wishing to escape from their familiar milieu. An equivalent longing motivates the hero’s departure from his childhood setting in popular tales in order to take possession of unknown parts of the outer (and inner) world. In Jensen’s story this aspect is represented by Miss Alice, the attractive lion trainer of the menagerie. Aspects like these are also unfolded in three other texts of Jensen to which ”Wombwell” is compared, ”Løverne” (“The Lions”), ”Circus Rieger” and ”Menageriet” (“The Menagerie”).
These texts point to a major generic issue in Jensen’s Himmerland stories, in that he navigates along the borderline between childhood remembrance and fictional creation, or between description and narration. That borderline becomes blurred and even disappears since the process of remembrance turns out to be much more creative than simply reconstructive.
”Jag satt till bords med de bästa”. Interkulturella möten i Vilhelm Ekelunds verk
Authors: Aronsson Mattias 
Published: February 2021

Abstract
The Swedish poet, essayist and aphorist Vilhelm Ekelund wrote extensively on the topic of foreign authors. Some of these writers represent the Greek and Roman cultural heritage; some belong to the modern-day literary canon. This article investigates the nature of these “intercultural encounters” in Ekelund’s body of work. By processing data from Andar i den Ekelundska sfären (1989) and Konkordans till Vilhelm Ekelunds skrifter (2000), we have been able to count all references made to the most important individuals appearing in Ekelund’s texts. At the top end of the table we find such prominent writers as Goethe (1343 references), Nietzsche (985) and Plato (503 references). We show that Ekelund’s oeuvre is largely dominated by male authors and philosophers of Western cultural heritage: the most prominently figured foreign nationalities being German (20,7%), Greek (10,1%), French (9,2%) and Roman (5,4%) writers. The quantitative method applied in our study is a good complement to more textcentered approaches to literature. In this case, it allows us to determine, with a great deal of accuracy, the extent and nature of the intercultural encounters in Vilhelm Ekelund’s body of work.
”Jeg tænker, altså er jeg en del af labyrinten.” – Zum Zusammenhang von System und Sprache in Inger Christensens brev i april
Authors: Schmidt Philipp-Sebastian 
Published: February 2021

Abstract
On the basis of the underlying mathematical permutation, Inger Christensen’s brev i april counts as part of her systemic poetry (’systemdigtning’). The form of the poem, structured by the mathematical permutation, becomes a carrier of significance which is interwoven with the content level of the poem by a pattern of motives. The possible infinity of the permutation as much as the periodical ending of it, refer in its double structure to the cyclic life of mankind. Furthermore, the structure of the poem emphasizes a profound skepticism towards language, which is the central aspect of the poem, and rais­es the question, if language can refer to the world and the things within it. The poem therefore discusses the human (in)ability to name the things in the world. Furthermore, it opens up the picture of a labyrinth between mankind and the world, i.e. the loss of the connection between them. The positive ending, ­however, is, on the basis of the periodical structure, not a guaranty for a positive future.
Litterær eksistensforskning. Eksklusion og marginalisering i Naja Marie Aidts Bavian
Authors: Svendsen Erik 
Published: February 2021

Abstract

Bavian (2006), Danish writer Naja Maria Aidt’s collection of short stories, is not only, as suggested by the title, about the animal in the human being. The stories are also about the ways human beings today are prone to exclude others. The texts are about people on the move and most often Aidt lets descriptions of bodily reactions and affect speak instead of talk and dialogue. However, it is significant for Aidt’s writing that the body never represents an idea about freedom – rather, the opposite of freedom. Moreover, personal freedom is not thought about as a way of escape to Aidt’s characters; it is more an alibi for disregarding others. The article suggests that Bavian maybe read as showing how ‘the naked life’ (Agamben) has been talking about is turning into a common lot.
A simple index of prediction accuracy in multiple regression analysis
Authors: Liu Xiaofeng Steven 
Published: February 2021

Abstract

Objectives
Within the context of multiple regression the coefficient of determination can be converted to a probability of agreement between the actual and predicted outcomes, suitably dichotomized.

Methods
This probability of agreement can be used as a simple index of prediction accuracy to help capture the probability of a correct prediction in multiple regression.

Results
The simple index of prediction accuracy makes the multiple correlation comprehensible to statisticians and laypeople alike. Two examples are provided to demonstrate the application of the simple index.

Conclusions
In short, the paper introduces the simple index, its computation formula, and its theoretical affinity to the confusion matrix, binomial effect size, probit model, and tetrachoric correlation.
Two-party key establishment: From passive to active security without introducing new assumptions
Authors: Neupane Kashi 
Published: February 2021

Abstract.
Key establishment protocols based on hardness assumptions, such as the discrete logarithm problem and the integer factorization problem, are vulnerable to quantum computer attacks, whereas the protocols based on other hardness assumptions, such as the conjugacy search problem and the decomposition search problem, can resist such attacks. The existing protocols based on the hardness assumptions which can resist quantum computer attacks are only passively secure. Compilers are used to convert a passively secure protocol to an actively secure protocol. Compilers involve some tools such as a signature scheme and a collision-resistant hash function. If there are only passively secure protocols but not a signature scheme based on the same assumption, then the application of existing compilers requires the use of such tools based on different assumptions. But the introduction of new tools, based on different assumptions, makes the new actively secure protocol rely on more than one hardness assumption.
We offer an approach to derive an actively secure two-party protocol from a passively secure two-party protocol without introducing further hardness assumptions. This serves as a useful formal tool to transform any basic algebraic method of public key cryptography to the real world applicable cryptographic scheme.

On Integral Bernstein Operators in Some Classes of Measurable Bivariate Functions
Authors: Taberski Roman 
Published: February 2021

Abstract
The two main theorems are cencerned with the approximation of (complex-valued) functions on the real plane by sums of Bernstein pseudoentire functions. They are formulated and proved in Section 4, after prior determination of the suitable integral operators. Analogous results for pseudopolynomial approximations were obtained by , Gonska, and Jetter ([Izv. Akad. Nauk SSSR, Ser. Mat. 34: 564-583, 1970],[J. Approx. Theory 48: 396-406, 1986]).
