Between ‘indiewood’ and ‘nowherewood’: American independent cinema in the twenty-first century
Authors: Tzioumakis Yannis 
Published: February 2015

Abstract
The article will argue that American independent cinema became increasingly polarized in the first decade of the twenty-first century. On the one hand, ‘indiewood’, a very particular iteration of independent film-making that, for some critics, comprises ‘features associated with dominant, mainstream conventions and markers of “distinction” designed to appeal to more particular niche-audience constituencies’, continued to be the most commercially successful and visible expression of American independent cinema. On the other hand, however, a low-key, low-budget cinema practised primarily through the means of digital technology and exhibited mainly away from the theatres in various online and other digital platforms, became also a representative of American independent cinema, despite its relative absence from the Academy Awards and other platforms that provide recognition. Both these expressions of independent film-making in the United States have engaged with a variety of issues and subjects, though the wealth of resources at the film-makers’ disposal in the first case and the relative absence of financial and other support in the second means that each type of independent film-making has engaged with its subject matter in distinct ways. In this respect, the article will also provide examples through which indiewood and more clearly independent films have approached their topics, paying particular attention to openly political issues – in this case, the impact of the global financial crisis and the ways in which it has been handled by the films.
A pharaoh and multiple deities: Writing the female self in Arab drama series
Authors: Al-Mahadin Salam 
Published: February 2015

Abstract
This article examines the referential aesthetics of constructing the self by some prominent actresses in Egyptian television drama series (musalsal). More specifically, it explores how the self is mediated through the roles these actresses assume, the doubling back of the role on the self and the final conflation between the two. Oscillating between the self as a spectacle (a fetishized object of visual pleasure) and the self as transgressor (the female as a monster or femme fatale), these constellations of selfhood should prompt us to query whether it is at all possible to conceive of an Egyptian female role not rooted in a patriarchal symbolic order or an androcentric fantasy. What these Egyptian actresses dramatically/visually seem to be demanding is to be seen and perceived as the same as the roles they are playing, a coherent self that both underlies/defines and unifies the role with the actress playing it. This article will demonstrate that such conflations have often led to disempowered gender formulations on the screen in the case of Egyptian drama series. Conversely, the absence of the cult of the superstar actress/actor in Syrian drama has allowed for more positive portrayals of women, not necessarily by banishing the female as a spectacle or transgressor, but by problematizing those elements within the textual politics of the script.
Qualitative analysis of a mathematical model for tumor growth under the effect of periodic therapy
Authors: Xu Shihe 
Published: February 2015

AbstractIn this paper, a mathematical model for a solid avascular tumor growth under the effect of periodic therapy is studied. Necessary and sufficient conditions for the global stability of tumor free equilibrium are given. The conditions under which there exists a unique periodic solution to the model are determined and we also show that the unique periodic solution is global attractor of all other positive solutions.
Role of D278N mutation for stability of prion dimer and tetramer structure
Authors: Jurkowski Wiktor 
Published: February 2015

Abstract
Toxicity of the prion molecule is a result of transmission of conformational change by direct contact with malignant misfolded molecule. The aim of this study is analyze the role of D278N mutation in promoting preferential oligomerization modes. Proteins exist as ensembles in equilibrium between different structural and dynamic states, including functionally relevant conformers as the most populated states as well as malfunctioning conformers as less populated states. Furthermore, the existence of different conformations allows protein oligomerization with condition-specific affinities. The maintenance of a particular role requires specific conversion between multiple stable states. Protein-protein binding may facilitate or may be a necessary condition of structural adaptation. In the case of prion disease, protein-protein interactions, resulting in prion agglomeration, have toxic effect. How exactly increased concentrations of prion oligomers trigger mechanisms leading to neuronal death is not known. Nevertheless, first oligomerization and second aggregate recognition are likely sequence of events that have to happen before any pathological condition may arise. Here, we carry out structural and dynamic analyses of the effect of disease-causing mutations on the dimerization and tetramerization of prion molecule as the first step in aggregate formation. D178N mutation has almost no effect on the monomeric structure but helps to stabilize the dimer, which consequently facilitates tetramer formation and stability.
Enhancers, enhancers – from their discovery to today’s universe of transcription enhancers
Authors: Schaffner Walter 
Published: February 2015

AbstractTranscriptional enhancers are short (200–1500 base pairs) DNA segments that are able to dramatically boost transcription from the promoter of a target gene. Originally discovered in simian virus 40 (SV40), a small DNA virus, transcription enhancers were soon also found in immunoglobulin genes and other cellular genes as key determinants of cell-type-specific gene expression. Enhancers can exert their effect over long distances of thousands, even hundreds of thousands of base pairs, either from upstream, downstream, or from within a transcription unit. The number of enhancers in eukaryotic genomes correlates with the complexity of the organism; a typical mammalian gene is likely controlled by several enhancers to fine-tune its expression at different developmental stages, in different cell types and in response to different signaling cues. Here, I provide a personal account of how enhancers were discovered more than 30 years ago, and also address the amazing development of the field since then.
Mathematical Modeling of the Mold Current and Its Influence on Slag and Ingot Behavior during ESR
Authors: Hugo Mathilde , Jardy Alain , Dussoubs Bernard , Escaffre Jessica , Poisson Henri 
Published: February 2015

AbstractElectroSlag Remelting (ESR) is widely used to produce high added value alloys for critical applications (aerospace industry, nuclear plants, etc.). In collaboration with Aubert & Duval, Institut Jean Lamour has been developing for several years a numerical transient model of an ESR heat. In the previous version of the model, the crucible was assumed to be perfectly electrically insulated from the electrode-slag-ingot system. However, this assumption must be challenged: the solidified slag skin at the slag/mold and ingot/mold interfaces may actually allow a fraction of the melting current to reach the crucible. In this paper, an evolution of the model is presented that enabled us to take into account the possibility of mold current. The simulation results were compared with actual experimental data. Sensitivity studies showed the influence of slag properties and operating parameters on the final quality of the ingot. Results highlighted that even a weakly conductive solidified slag skin at the inner surface of the model can be responsible for a non-negligible amount of current circulating between the slag and crucible, which modifies the fluid flow, heat transfer and solidification of both the slag phase and the metallic ingot.

Authors: Kovács György , Farkas József 
Published: February 2015

AbstractThis study shows the optimization method for a new complex structural model: laminated carbon fiber-reinforced plastic (CFRP) deck plates with polystyrene foam (EPS) inner core. The structure is designed for both minimal cost and minimal weight, taking into consideration the design constraints as follows: maximum deflection of the total structure, stress in the composite plates, stress in the polystyrene foam, eigenfrequency of the structure, thermal insulation of the structure, and size constraints for the design variables.
A New Generalized Algebraic Method and its Application in Nonlinear Evolution Equations with Variable Coefficients
Authors: Bai Cheng-Lin , Bai Cheng-Jie , Zhao Hong 
Published: February 2015

Abstract
In this paper, a new generalized algebraic method is proposed to construct a series of explicit exact solutions of general nonlinear evolution equations with variable coefficients. Compared with most existing methods, such as the tanh method, the extended tanh method, the Jacobi elliptic function method or the algebraic method, the proposed method seems to be more powerful. The efficiency of the method is demonstrated by applying it to the (1+1)-dimensional variable coefficients modified Korteweg-de Vries (MKdV) equation and the (2+1)-dimensional variable coefficients Kadomtsev- Petviashvili (KP) equation. A rich variety of new exact explicit solutions has been found. - PACS numbers: 03.40.Kf; 03.65.Fd; 02.30Jr.
Symbolic Computation and Non-travelling Wave Solutions of the (2+1)-Dimensional Korteweg de Vries Equation
Authors: Wang Dengshan , Zhang Hong-Qing 
Published: February 2015

Abstract
In this paper, with the aid of symbolic computation we improve the extended F-expansion method described in Chaos, Solitons and Fractals 22, 111 (2004) to solve the (2+1)-dimensional Korteweg de Vries equation. Using this method, we derive many exact non-travelling wave solutions. These are more general than the previous solutions derived with the extended F-expansion method. They include the Jacobi elliptic function, soliton-like trigonometric function solutions, and so on. Our method can be applied to other nonlinear evolution equations.
New Exact Solutions and Fractal Localized Structures for the (2+1)-Dimensional Boiti-Leon-Pempinelli System
Authors: Fang Jian-Ping , Ren Qing-Bao , Zheng Chun-Long 
Published: February 2015

Abstract
In this work, a novel phenomenon that localized coherent structures of a (2+1)-dimensional physical model possess fractal properties is discussed. To clarify this interesting phenomenon, we take the (2+1)-dimensional Boiti-Leon-Pempinelli (BLP) system as a concrete example. First, with the help of an extended mapping approach, a new type of variable separation solution with two arbitrary functions is derived. Based on the derived solitary wave excitation, we reveal some special regular fractal and stochastic fractal solitons in the (2+1)-dimensional BLP system. - PACS: 05.45.Yv, 03.65.Ge

Published: February 2015

Abstract
Dust acoustic solitary waves are investigated on the nonlinear, unmagnetized homogeneous dust ion and dust ion electron plasma with the effects of dust streaming. The Sagdeev’s pseudopotential is determined in terms of ud, the dust ion speed. It is found that there exist a critical value of ud, beyond which the solitary waves cease to exist.
The First Measured Stark Width and Shift of the 402.6186 nm He I Line
Authors: Djeniže Stevan , Srećković Aleksandar , Bukvić Srdjan 
Published: February 2015

Abstract
Stark width (W) and shift (d) of the neutral helium (He I) 402.6186 nm spectral line in the high lying 2p-5d transition have been measured in the optically thin helium plasma created in a linear, low-pressure, pulsed arc discharge at a 52,000 K electron temperature and 1.3 · 1023 m−3 electron density. Obtained data are the first experimental values of the Stark width and shift related to the mentioned He I spectral line. Direct comparison with theoretical results is not possible due to the fact that available data are calculated for considerably lower electron densities. We found that at 1023 m−3 electron density the lowering of the effective ionization energy has influence on the number and contribution of the perturbing energy levels, especially in the case of the high lying parent energy level of the particular transition. This effect generates lower Stark widths in the high lying He I transitions than the existing theoretical approximations provide. We have found negative Stark shift.
A pozsonyi egyetemalapítás az oktatási helyszínek tükrében
Authors: Schmelczer-Pohánka Éva 
Published: February 2015

There were many plans for placing the faculties and institutes of the Royal Erzsébet University (founded in 1912). Some of these would have placed the campus in the inner city area, while others intended it for the outskirts of the city. The start of the First World War had a significant effect on the operation and the development of the university venues. Finally, the University in Pozsony was able to start instruction after moving into already existing buildings. This study provides an overview of this process, the various plans and the buildings that were eventually used.

Az Erzsébet Tudományegyetem pécsi épületei
Authors: Pilkhoffer Mónika 
Published: February 2015

Founded in 1912, the Erzsébet University of Pozsony found its home in Pécs following the disintegration of historic Hungary. In 1921, shortly after the Serbian occupation of the town ended, the only way the university could find a home was to have buildings donated to the institute. As the cadet academy, the only big enough structure, was not available, the faculties, institutes and clinics of the university began operations in 1923 in buildings located in 19 different points around town. The clinics of the university found appropriate housing thanks to the numerous medical institutes of the town, but the theoretical institutes, especially the faculties of law and humanities were constantly lacking sufficient space. The period between the two world wars did not see such large scale university investments as those in Szeged or Debrecen, but a few new structures were built: in 1929 the Szent Mór College was consecrated, in 1931 the teachers’ living quarters was erected, and by 1934 the new faculty of law building and in 1939 the gymnasium were completed. Although the idea of a joint campus has emerged a few times, the buildings of the university are still scattered around Pécs to this day.

Az egyetemi infrastruktúra kiépülése a Ferencz József Tudományegyetem Szegedre kerülését követően
Authors: Kiss Róbert 
Published: February 2015

Due to the war situation in Transylvania in 1919, the Ferencz József University was forced to flee the city of Kolozsvár. After a short stay in Buda, the Ministry of Religion and Education and the political leaders of Szeged negotiated its relocation to Szeged. In the five-year period following the university’s opening in October 1921, it experienced hardships and everyday operational problems, but from 1926 it received significant state resources thanks to the Minister of Religion and Education, Kuno Klebersberg. Although the Great Depression resulted in the depletion of these resources, as a result of the prior constructions and investments, the university could find its final home in Szeged, and could become a modern think tank of Western European standards.

Comparison of the exposure‐excretion relationship between men and women exposed to organic solvents: Toshio Kawai, et al. Osaka Occupational Health Service CenterObjectiveThe present study was initiated to examine if application of the same biological occupational exposure limits (BOELs) for organic solvents is applicable across the sexes.MethodsA survey was conducted in 69 microscale enterprises in a furniture‐producing industrial park. In practice, 211 men and 52 women participated in the survey. They worked in a series of production process, and were exposed to solvent vapor mixtures. The exposure intensities were monitored with two types of diffusive samplers, one with carbon cloth (for solvents in general) and the other with water (for methyl alcohol) as adsorbents. Solvents in the adsorbents and headspace air from urine samples were analyzed with capillary FID‐GC. The measured values were subjected to linear regression analysis followed by statistical evaluation for possible sex‐related differences in slopes.ResultsEssentially no significant difference was detected between men and women in regression line parameters including slopes. Possible differences in the cases of acetone and toluene were discussed and excluded.ConclusionsWith the exceptions for acetone and toluene, the present study did not detect any clear differences between men and women. In examinations of past reports, no support for the observed differences was found. The present findings deserve further study so that a solid conclusion can be formed.

Published: February 2015

ABSTRACTThis article discusses novel algorithms for molecular-dynamics (MD) simulations with short-ranged forces on modern multi- and many-core processors like the Intel Xeon Phi. A task-based approach to the parallelization of MD on shared-memory computers and a tiling scheme to facilitate the SIMD vectorization of the force calculations is described. The algorithms have been tested with three different potentials and the resulting speed-ups on Intel Xeon Phi coprocessors are shown.
Bimetallic PdCu Nanoparticle Catalyst Supported on Hydrotalcite for Selective Aerobic Oxidation of Benzyl Alcohol
Authors: Nishimura Shun , Yoshida Nao , Ebitani Kohki 
Published: February 2015

ABSTRACTTo decrease the amount of precious metal usage for Pd-catalyzed aerobic alcohol oxidation, various amount of Cu-contained Pd bimetallic nanoparticle-supported solid base hydrotalcite catalyst (PdxCuy-PVP/HTs) were prepared and applied for aerobic benzyl alcohol oxidation. It was found that the addition of Cu atoms into Pd in the range of 0-40% provided a similar or a little superior activity to that of Pd100-PVP catalyst, whereas a large quantity of co-existence Cu (>40%) gradually decreased their activity of the catalyst. The aerobic benzyl alcohol oxidation over Pd80Cu20-PVP/HT served 77% yield and 95% selectivity towards benzaldehyde at 313 K for 5 h in toluene under O2 flow. X-ray adsorption spectroscopy (XAS) studies and scanning transmission electron microscopy-high angle annuar dark field (STEM-HAADF) with energy dispersive X-ray spectroscopy (EDS) analyses suggested that Cu atoms doping into Pd(0) NP influenced not only localized nanostructure but also oxidation state around Pd atoms. We suggested that substitution of precious metal with small amount of transition metals such as Cu lead to geometric/electronic changes in active sites would be one of nice strategies for reducing the cost for the catalyst in the oxidation process.

Zwei Landpfarreien im Umbruch: Agrarmodernisierung in der Po-Ebene im Zeichen von politischer Konfrontation und Mentalitätswandel (1850–1914)
Authors: Fincardi Marco 
Published: February 2015

Two Parishes in Turmoil: Modernization in the Valley of the Po Between Political Confrontation and Changing Mentalities (1850–1915) From the 1860s, the modernization of agriculture was generating a far-reaching crisis in the rural society of the Po valley, which was dominated by the clergy and the landed nobility. The micro-history of two local communities throws light upon the effects of this structural crisis from the viewpoint of the village priest and of the changes in village life. The economic inequalities and social tensions became so acute that from the 1880s the social life of the commune was increasingly polarized between the newly emerging counter-culture of day labourers and artisans united by secular and socialistic values on the one hand, and the new class of tenant farmers and agrarian bourgeoisie on the other. Leadership of the latter was taken over by the priests who from 1910 organised the opposition of the small farmers and leaseholders against the rise of socialist trade unions and cooperative movements among the farm labourers. The political and social confrontation in both communities may be interpreted as a conflict that had its roots in the changing mental attitudes of rural society, whose leading groups were particularly susceptible to urban lifestyles and examples.
Cinéma et religion dans l'Europe du XXe siècle
Authors: Sorlin Pierre 
Published: February 2015

Film and Religion in 20th Century Europa The article focuses on the conflict zones and compromises of the ambivalent relationship which developed between film and religion in Europe. European film production was more reluctant than Hollywood to treat Biblical themes; on the other hand, the Christian Churches oscillated between damning, controlling and producing their own films. Their censorship and criticism were frequently the occasion of stormy internal debates about Church strategy toward the decline of traditional religiosity. Subjects such as the position and role of the pastor in his congregation and the lives of the saints were made into films; specific religious themes, however, remained rare. For the historian, these films offer symptomatic indicators of sensitivities, complex problems and uncertainties concerning religious life at the time.
