Matrices induced by arithmetic functions,
primes and groupoid actions of directed
graphs
Authors: Cho Ilwoo , Jorgensen Palle E. T. 
Published: July 2015

Abstract
In this paper, we study groupoid actions acting on arithmetic functions. In particular, we are interested
in the cases where groupoids are generated by directed graphs. By defining an injective map α from
the graph groupoid G of a directed graph G to the algebra A of all arithmetic functions, we establish a corresponding
subalgebra AG = C*[α(G)]︀ of A. We construct a suitable representation of AG, determined both by
G and by an arbitrarily fixed prime p. And then based on this representation, we consider free probability on
AG.
Catalytic Supramolecular Photochirogenesis
Authors: Yan Zhiqiang , Wu Wanhua , Yang Cheng , Inoue Yoshihisa 
Published: July 2015

AbstractSupramolecular photochirogenesis is a new strategy for circumventing the inherent difficulties encountered in conventional photochirogenesis, i.e. the interactions associated with geometrically less-defined, short-lived excited states, by confining a prochiral substrate(s) in a chiral supramolecular environment(s) prior to photoexcitation. This rather simple, but very successful, strategy has been applied to a variety of chiral photoreactions. However, a stoichiometric, or even excess amount of supramolecular host is often needed to ensure full complexation of the substrate, and achieve the optimum stereochemical outcome. This apparent drawback has recently been removed by introducing a sensitizing moiety to the supramolecular host, or by bathochromically shifting the absorption band of substrate through Lewis acid, or charge-transfer complexation. Recent progress in catalytic supramolecular photochirogenesis will be reviewed.
Taxonomic Revision Of The Striativentre Species Group Of The Genus Tetramorium (Hymenoptera, Formicidae)
Authors: Radchenko A. G. , Scupola A. 
Published: July 2015

Abstract
The Tetramorium striativentre species group is revised. Workers and queens of the species of this group are characterized by the unique for all other Palaearctic Tetramorium species feature: the first gastral tergite, or at least its anterior half, is very densely and distinctly longitudinally striato-punctated. We place six species to this group, including two new ones: T. striativentre Mayr, T. schneideri Emery, T. kabulistanicum Pisarski, T. saudicum Sharaf, T. sabatinellii sp. n. from Jordan, and T. pisarskii sp. n. from Afghanistan. Additions to the diagnosis of T. striativentre and T. schneideri and the first descriptions of males of these two species are provided, and a key to species of this group is compiled.
New Records Of The Dipteran Genera Triphleba (Phoridae) And Prosphyracephala (Diopsidae) In Rovno And Baltic Ambers
Authors: Perkovsky E. E. , Mostovski M. B. , Henderickx H. 
Published: July 2015

Abstract
Dipteran insects constitute 51 % among arthropods of the Rovno Amber. There are 99 species and 23 genera of the Diptera described from the Rovno Amber; however, to date only 32 species are shared with the Baltic Amber fauna, including two species that are treated in this paper. Triphleba schulmanae Brown, 2003 (Phoridae), originally described from the Baltic Amber, is recorded in the Rovno Amber for the first time and its amended description is supplied. Genus Prosphyracephala Hennig, 1965 (Diopsidae), earlier known from the Baltic and Saxonian ambers, the Upper Eocene of Ruby River (Montana, USA) and the Lower Oligocene of Céreste (France), is recorded in the Rovno Amber for the first time. Prosphyracephala aff. succini (Loew, 1873) is the first diopsid record from Ukraine. A second specimen of Prosphyracephala kerneggeri Kotrba, 2009 is found in the Baltic amber; the complete wing venation is described for the first time for this species. Vast majority of the Old World Diopsidae are strictly thermophilous. In fact, all of them but the five species of brevicornis group of Sphyracephala Say (three Palearctic and two Nearctic ones) frequent tropic and the warmest subtropic areas, however the thermophilous Diopsidae are known in the New World neither in past nor in contemporary fauna.
Genetic Regulation of Dna2 Localization During the DNA Damage Response
Authors: Yimit Askar , Riffle Michael , Brown Grant W 
Published: July 2015

AbstractDNA damage response pathways are crucial for protecting genome stability in all eukaryotes. Saccharomyces cerevisiaeDna2 has both helicase and nuclease activities that are essential for Okazaki fragment maturation, and Dna2 is involved in long-range DNA end resection at double-strand breaks. Dna2 forms nuclear foci in response to DNA replication stress and to double-strand breaks. We find that Dna2-GFP focus formation occurs mainly during S phase in unperturbed cells. Dna2 colocalizes in nuclear foci with 25 DNA repair proteins that define recombination repair centers in response to phleomycin-induced DNA damage. To systematically identify genes that affect Dna2 focus formation, we crossed Dna2-GFP into 4293 nonessential gene deletion mutants and assessed Dna2-GFP nuclear focus formation after phleomycin treatment. We identified 37 gene deletions that affect Dna2-GFP focus formation, 12 with fewer foci and 25 with increased foci. Together these data comprise a useful resource for understanding Dna2 regulation in response to DNA damage.
Classical and Bayesian Estimation of Reliability in Multicomponent Stress-Strength Model Based on Weibull Distribution
Authors: Kizilaslan Fatih , Nadar Mustafa 
Published: July 2015

<p>In this study, we consider a multicomponent system which has k independent and identical strength components X1,...,Xk and each component is exposed to a common random stress Y when the underlying distributions are Weibull. The system is regarded as operating only if at least s out of k (1 ≤ s ≤ k) strength variables exceeds the random stress. We estimate the reliability of the system by using frequentist and Bayesian approaches. The Bayes estimate of the reliability has been developed by using Lindley's approximation and the Markov Chain Monte Carlo methods due to the lack of explicit forms. The asymptotic confidence interval and the highest probability density credible interval are constructed for the reliability. The comparison of the reliability estimators is made in terms of the estimated risks by the Monte Carlo simulations.</p>

Published: July 2015

ABSTRACTSynthesis, structural, magnetic properties and heating efficiency of γ-Fe2O3 nanoparticles have been investigated. X-ray diffraction (XRD) and Mössbauer spectroscopy show that the obtained nanoparticles are mainly composed of maghemite phase (γ-Fe2O3). Williamson-Hall method shows that the crystallite is around 14nm.The specific absorption rate (SAR) under an alternating magnetic field is investigated as a function of frequency. A highest SAR value of 12W/g for frequency 523 kHz was obtained.
The Properties of Dual Acceptor Delta-Doped ZnO Thin Films
Authors: Oder T N. , Gade R.C. , Merlo C. 
Published: July 2015

ABSTRACTWe report the investigation of ZnO thin films delta-doped with lithium and phosphorus introduced simultaneously. The films were deposited from high purity ceramic targets of ZnO and Li3PO4 on c-plane sapphire substrates by RF magnetron sputtering. An undoped ZnO film with a low background electron concentration was used as the buffer layer on the sapphire substrate. The doped films were prepared by carrying simultaneous sputtering from the ZnO and Li3PO4 ceramic targets. For uniform doped films, the simultaneous deposition from the ZnO and Li3PO4 was uninterrupted. For the delta-doped films on the other hand, deposition from the ZnO target was uninterrupted while that from the Li3PO4 was interrupted periodically using a shutter. Post-deposition annealing was carried using a rapid thermal processor in O2 at 900 oC for 3 min. Results obtained from photoluminescence spectroscopy measurements at 12 K revealed acceptor-related luminescence peaks at 3.35 eV, possibly due to the transition from exciton bound to a neutral acceptor. The x-ray diffraction 2θ-scans showed a single peak at about 34.4o. Hall effect measurements revealed p-type conductivities with an average Hall concentrations of 3.8 x 1013 cm-3 in uniform doped samples and 1.5 x 1016 cm-3 in delta doped samples. However, in some cases the Hall coefficients had both positive and negative values, making the determination of the carrier type inconclusive. The fluctuation in the carrier type could be due to the lateral inhomogeneity in the hole concentration caused by signal noise impacting the small Hall voltages in the measurements.
European Scales and Institutional Transformation in Russian Higher Education
Authors: Drantusova Natalya , Knyazev Evgeniy 
Published: July 2015

We have analyzed how integration into the European education space affects the Russian higher education system. Two common European trends have been studied as driving forces of transformation: 1) institutional differentiation based on introducing the multi-level education system and 2) reform of the relationship between the higher education and the mass public. It appears that the multi-level system is implemented in Russian higher education through a State-initiated vertical differentiation of higher education institutions based on their research and development achievements and through a concentration of resources in a limited number of leading universities. We believe that an institutional differentiation like that, with different program levels, discards some crucial points: heterogeneity in the group of leading universities that get the pre-emption right to implement Master’s programs; inherent heterogeneity of individual higher education institutions that may have both high R&D potential departments and mass-market oriented ones; the danger of inhibiting the enthusiasm of universities by imposing rigid limitations on their activities, while Master’s degrees remain merely a source of profit for them. We are convinced that no consistent cooperation between employers and higher education in Russia is explained by the fact that, being guided by the Bologna Process principles, higher education outstripped employers by developing educational standards long before most industries adopted their occupational standards. We have singled out four models of university activities in the context of higher education system transformation: 1) research university, 2) system integration university, 3) regional integration university, and 4) human resource construction university.
Russian science and higher education in a more global era
Authors: Marginson Simon 
Published: July 2015

Since the end of the Soviet period much has changed, though in higher education and science, the world outside Russia may have changed more than the world within. In the Internet era all national research systems have become partly subsumed in the one English-language global science system, while still retaining distinct national identities. Most innovations in technology and product development are now sourced wholly or partly from global sources. It is essential to become very good at accessing global science, which means producing global science, and collaborating with others. Russian science remains surprisingly decoupled from world science. Global publication and citation rates at the leading universities are ver y low compared to their counterparts abroad. Between 1995 and 2012, international co-authorship of journal papers increased by 168 per cent at world level, and multiplied by ten times in China, but internationally joint papers rose by only 35 per cent in Russia. The lack of internationalization of Russian universities and science, coupled with the continued running down of the Soviet legacy, contributes to the country’s weak performance in research rankings, both objectively (real research paper output is falling, and Russia has been left well behind by dynamic developments in China and the rest of East Asia, and to a lesser extent by Brazil and India) and also subjectively (there are substantial national research strengths in areas like engineering, manufacturing, engineering and strategic industries but the work is mostly done in Russian and not published in global journals, so it is invisible). Achieving five universities in the world top 100, the national policy goal, is a long way off. It has taken China and Singapore two decades to build world-class systems and policy makers in Russia need a long view. There is real scope for rapid improvement however. Currently low levels of internationalization are a strategic opportunity. When cross-border cooperation, publishing, and benchmarking are stepped up significantly, as in the East Asian science systems, major gains can be made in Russia.

AQUÉM DA LINGUAGEM
Authors: Oliveira Mariana Camilo de 
Published: July 2015

A aporia entre trauma e representação, presente na poesia celaniana, é amiúde contraposta ao “dictum” adorniano da impossibilidade da lírica após Auschwitz. No presente trabalho, pretende-se discorrer sobre tal aporia, a partir do legado de Celan. Vislumbra-se a saída do impasse através de uma ética da representação, que não repete o trauma obscenamente ou se cala, mas incorpora o silêncio. Assim, a poética de Celan cita o ocorrido, evocando-o metonimicamente, à maneira da madeleine proustiana. Deparamo-nos com uma lírica indicial que, como cicatriz ou ruína, é contígua à memória.

MACUNAÍMA, CARÁTER DA DESCONSTRUÇÃO OU DESCONSTRUÇÃO DO CARÁTER?
Authors: Timbó Eduardo 
Published: July 2015

O presente trabalho parte inicialmente da ideia suscitada por Jacques Derrida de que os limites entre literatura e filosofia não são facilmente identificados. A partir disso realizaremos uma aproximação entre Macunaíma, o herói sem nenhum caráter, livro de Mário de Andrade que se tornou expoente do Modernismo brasileiro, e a desconstrução derridiana, “abordagem filosófica” assim nomeada por Derrida.
APROPRIAÇÕES DA DESCONSTRUÇÃO PELA CRÍTICA LITERÁRIA
Authors: Losano Carmen Cristiane Borges 
Published: July 2015

A teoria da Desconstrução, “apropriada” pelos Estudos Culturais, promove uma revisão de conceitos e critérios da crítica literária, de forma a colaborar na valorização das manifestações artísticas e/ou culturais, independentemente dos velhos critérios de consagração das obras. Enfim, a valorização do que se denomina “arte menor”se deve, justamente, a Jacques Derrida.

TEMPORALIDADE E DIFFÉRANCE: DERRIDA, LEITOR DE FREUD E HUSSERL
Authors: Serra Alice Mara 
Published: July 2015

Primeiramente, serão examinados os sentidos em que as teorias de Freud sobre o a posteriori e o traço psíquico contribuem para a formulação de figuras de pensamento centrais da desconstrução: o traço, a arqui-escritura, a différance. Em seguida, será tematizada a crítica de Derrida à filosofia da presença de Husserl. Enfim, será questionado se se trata de manter a polarização estabelecida por Derrida entre o pensamento de Husserl e o pensamento da différance.
AS APORIAS DA RESPONSABILIDADE: HERESIA E SEGREDO EM DONNER LA MORT, DE DERRIDA, E TEMOR E TREMOR, DE KIERKEGAARD
Authors: Carvalho Maria Elvira Malaquias de 
Published: July 2015

Em Donner la mort, Jacques Derrida estuda a história do conceito de responsabilidade, construindo uma argumentação que torna relevantes as aporias que cercam a apreensão de tal conceito. O texto destaca como o autor empreende a releitura de Temor e Tremor, obra em que Kierkegaard analisa a crise de Abraão no relato bíblico do sacrifício de Isaac. Ao final, são dados os motivos pelos quais Derrida alega que a literatura herda e renega, ao mesmo tempo, a filiação abraâmica a ela atribuída.

A barbárie em campo
Authors: Muinhos Breno Pauxis 
Published: July 2015

O jornalista e escritor uruguaio Eduardo Galeano utiliza como cenário a América Latina em muitos de seus textos. Os assuntos traçam desde a política (fortemente discutida em As Veias Abertas da América Latina) do período colonial, passando pela devoção religiosa latino-americana, traçando heróis e vilões de nossa cultura, até reflexões críticas e apaixonadas sobre o futebol. E é sobre Literatura e barbárie, como categoria estética, que este trabalho se debruçará. Em Futebol ao sol e à sombra, tradução de Eric Nepomuceno, o premiado escritor uruguaio desvela as maravilhas do jogo e suas personagens, e as amarguras e maquinações políticas e comerciais que cercam a "festa pagã". No presente artigo, as crônicas As lágrimas não vêm do lenço, Os sacrifícios da festa pagã, Os cânticos do desprezo e O pecado de perder serão os objetos de enfoque, nos quais irá se observar e analisar os elementos da barbárie e da crônica.

Medidas abolicionistas en la Nueva Granada, 1814–1851
Authors: Restrepo Eduardo 
Published: July 2015

The paper focuses on the analysis of the narrative of various abolitionist acts and the impact they had on the problematization of slavery. The author argues that, from the very beginning, the analysis of abolitionist acts manifests a contradiction with the independence discourse with regards to the idea of maintaining a part of the population as slaves. Yet, in practice, the acts aimed less at the brining into being of citizens and more in providing guarantees to slave-owners of compensation as well as preventing, by means of individualized surveillance and other instruments of control like concertaje, that the liberated participate in the distribution of the wealth and prestige and they are kept on the margins of society.
