Representaciones culturales, narraciones y estéticas: La emergencia de las divas en el campo cultural latinoamericano: representaciones artísticas en la crónica modernista
Authors: Viu Adagio Julieta 
Published: November 2019

Las crónicas que Rubén Darío publica en la prensa chilena y Manuel Gutiérrez Nájera en la mexicana consolidan, a fines del siglo XIX, a la diva como tópicoliterario. Estas producciones forjan un imaginario que celebra la belleza, la armonía y la exclusividad y que por ello resulta contestatario de la concepción burguesa del arte y de la vida que rige las sociedades latinoamericanas finiseculares. En este artículo, consideramos las representaciones que los modernistas mencionados realizan de Sarah Bernhardt y Adelina Patti para analizar la emergencia del divismo, esto es, una narración donde la hegemonía de la estrella logra desplazar a un segundo plano a la obra interpretada. Contrastaremos este corpus con la crítica teatral que Paul Groussac escribe sobreSarah Bernhardt focalizada en la actriz y sus habilidades para la interpretación.
Producción audiovisual, políticas culturales y de la memoria: Documentales, justicia y memorias. Repre- sentación de los juicios a responsables de las dictaduras de los ’70 en Argentina y Chile
Authors: Nicola Mariné 
Published: November 2019

En este trabajo nos proponemos analizar las producciones audiovisuales documentales sobre los juicios en torno a los delitos cometidos durante las dictaduras cívico–militares de la década de los ’70 en el caso argentino y chileno. Al mismo tiempo, considerar a estos filmes en el proceso deconstrucción de memorias y su relación con las políticas de la memoria delineadas y desarrolladas en ambos países en torno a la producción audiovisual.Nos planteamos trabajar de manera comparativa las producciones documentales que representen los procesos judiciales en el caso argentino y el caso chileno, poniendo en tensión, por un lado, la relación historia–cine, hechos comprobables–representación de la realidad y, por otro, producción audiovisual y construcción de memorias. Cabe aclarar que el foco de indagación se condensa en la representación de los juicios y las memorias que entran en disputa, pujan, luchan en las tramas narrativas de los audiovisuales que toman este tema como central para sus producciones. Se estudia comparativamente de forma sincrónica dos casos con ciertas similitudes en la implantación e implementación de las dictaduras cívico–militares,pero con notables diferencias en los procesos de transición democrática, juzgamiento a los responsables y delineamientos de políticas de memoria, abordando el análisis comparativo en cuanto a lo que sucede con el juzgamiento y la representación fílmica de estos procesos en ambos países.Los objetivos que guían esta investigación se proponen considerar los documentales según país de procedencia, marcando diferencias en la modalidad derepresentación: qué elementos y recursos utilizan, cómo representan los acontecimientos y qué memorias entran en disputa en sus narrativas; indagar sobre las estrategias, recursos y dispositivos utilizados para la representación de los juicios.
Eigenvalues for a class of singular problems involving p(x)-Biharmonic operator and q(x)-Hardy potential

Published: November 2019

Abstract
In this paper, we consider the nonlinear eigenvalue problem:

$$\begin{array}{}
\displaystyle
\begin{cases}
{\it\Delta}(|{\it\Delta} u|^{p(x)-2}{\it\Delta} u)= \lambda \frac{|u|^{q(x)-2}u}{{\delta(x)}^{2q(x)}} \;\; \mbox{in}\;\; {\it\Omega}, \\
u\in W_0^{2,p(x)}({\it\Omega}),
\end{cases}
\end{array}$$
where Ω is a regular bounded domain of ℝN, δ(x) = dist(x, ∂Ω) the distance function from the boundary ∂Ω, λ is a positive real number, and functions p(⋅), q(⋅) are supposed to be continuous on Ω satisfying

$$\begin{array}{}
\displaystyle
1 \lt \min_{\overline{{\it\Omega} }}\,q\leq \max_{\overline{{\it\Omega}}}\,q \lt \min_{\overline{{\it\Omega} }}\,p \leq \max_{\overline{{\it\Omega}}}\,p \lt \frac{N}{2} \mbox{ and } \max_{\overline{{\it\Omega}}}\,q \lt p_2^*:= \frac{Np(x)}{N-2p(x)}
\end{array}$$
for any x ∈ Ω. We prove the existence of at least one non-decreasing sequence of positive eigenvalues. Moreover, we prove that sup Λ = +∞, where Λ is the spectrum of the problem. Furthermore, we give a proof of positivity of inf Λ > 0 provided that Hardy-Rellich inequality holds.
Gapless Lines and Gapless Proofs: Intersections and Continuity in Euclid’s Elements
Authors: De Risi Vincenzo 
Published: November 2019

Abstract
In this paper, I attempt a reconstruction of the theory of intersections in the geometry of Euclid. It has been well known, at least since the time of Pasch onward, that in the Elements there are no explicit principles governing the existence of the points of intersections between lines, so that in several propositions of Euclid the simple crossing of two lines (two circles, for instance) is regarded as the actual meeting of such lines, it being simply assumed that the point of their intersection exists. Such assumptions are labelled, today, as implicit claims about the continuity of the lines, or about the continuity of the underlying space. Euclid’s proofs, therefore, would seem to have some demonstrative gaps that need to be filled by a set of continuity axioms (as we do, in fact, find in modern axiomatizations).
I show that Euclid’s theory of intersections was not in fact based on any notion of continuity at all. This is not only because Greek concepts of continuity (such as the Aristotelian ones) were largely insufficient to ground a geometrical theory of intersections, but also, at a deeper level, because continuity was simply not regarded as a notion that had any role to play in the latter theory. Had Euclid been asked to explain why the points of intersections of lines and circles should exist, it would have never occurred to him to mention continuity in this connection. Ancient geometry was very different from ours, and it is only our modern views on continuity that tend to give rise to the expectation that this latter must be included in the foundations of elementary mathematics.
We may hope to reconstruct Euclid’s views on intersections if we undertake a critical examination both of the extension and of the limits of ancient diagrammatic practices. This is tantamount to attempting to understand to what extent the existence of an intersection point may be inferred just from the inspection of a diagram, and in which cases we need rather to supplement such inference by propositional rules. This leads us to discuss Euclid’s definition of a point, and to work out the details of the complex interaction between diagrams and text in ancient geometry. We will see, then, that Euclid may have possessed a theory of intersections that was sufficiently rigorous to dispel the main objections that could be advanced in antiquity.
Die Inszenierung von Text- und Werkgenesen in Dichter-, Künstler- und Komponistenhäusern
Authors: Plachta Bodo 
Published: November 2019

Abstract
The homes of poets, artists and composers are not only memorials and biographical museums but also places in which texts, pieces of art and music were created. A person’s biography is quickly revealed in these homes by looking at the original furniture and the typical objects of daily life common at the time. To make the creative work visible though, guidance and explanations are necessary. In many homes the pieces of work aren’t merely shown, instead, an attempt has been made to provide specific insight into the process of the creation of them. Not only are the relevant documents shown but also, using various media, the origins of the pieces are made comprehensible to the beholder. The origins are staged. Sometimes, with the help of drawers which can be opened, the stages of the origins can be contemplated (Franz Schubert, Wolfgang Koeppen) and then the manuscripts are illustrated in the order of their creation on a time beam (Honoré de Balzac). In Heinrich-Schütz’s home the development of a melody can be followed acoustically. But there are also homes in which their owners – mainly visual artists – even developed concepts for the keeping and archiving of the creation of their works (Gustave Moreau, Auguste Rodin) during their lifetimes, so that the observer can later experience them in all their authenticity in their original surroundings. In this article various forms of conveying the creation of works are presented, commented on and placed in the exploration context of places of creativity.
Vom Nutzen der Hybridedition
Authors: Kocher Ursula 
Published: November 2019

Abstract
The paper deals with the question, in which cases hybrid editions are indeed useful and not merely a duplication of the same content. Based on brief terminological considerations it examines which arguments are generally presented for this type of edition. In addition, the exemplarily selected hybrid editions show which concepts have led to this kind of presentation. Finally, the resulting requirements for hybrid editions are collated with the approach of the hybrid edition of Kurt Schwitters. Alle Texte (http://schwitters-digital.de).
The Effects of Micronutrient and Organic Fertilizers on Yield and Growth Characteristics of Sunflower (Helianthus annuus L.)

Published: November 2019

Abstract
To evaluate the effect of different micronutrients (Mn, Fe, Zn) and farmyard manure (FYM) on the vegetative, phenological, and achene yield components of sunflower a field experiment was conducted in Maragheh, North West of Iran during the growing season 2018–2019. The treatments were arranged in a split-plot design- with three replicates. The main plots assigned to two levels of FYM (0 and 20 t ha−1) and sub plots assigned to the recommended dose of three micronutrients (Mn, Fe, Zn). The results revealed significant improvements in the growth and yield of sunflower due to the main and interaction effects of farmyard manure and inorganic fertilizer application. The highest number of leaves and the highest leaf area was observed in a plant grown by FYM + Zn. However, there was no significant difference between micronutrients under inorganic condition (without FYM application). The highest leaf relative water content (RWC), plant height, internode distance, and chlorophyll was recorded for plants grown by Fe or Zn under FYM applied condition. Application of FYM and micronutrients reduced the number of days to flowering. However, the application of FYM significantly delayed plant maturity. Achene number per head, 100-achene weight, achene length, achene width, achene oil percent, achene yield, and harvest index significantly increased with the application of FYM and the best performance was in a plant grown by FYM + Zn and FYM + Fe. The percentage of hollow and empty achene was significantly reduced by the application of FYM. Combined applications of FYM and micronutrients has become an increasingly common practice.
The Political Role of Business Magnates in Competitive Authoritarian Regimes
Authors: Pleines Heiko 
Published: November 2019

Abstract
This contribution examines the role of business magnates (“oligarchs”) in political transitions away from competitive authoritarianism and towards either full authoritarianism or democracy. Based on 65 cases of competitive authoritarian regimes named in the academic literature, 24 historical cases with politically active business magnates are identified for further investigation. The analysis shows that in about half of those cases business magnates do not have a distinct impact on political regime change, as they are tightly integrated into the ruling elites. If they do have an impact, they hamper democratization at an early stage, making a transition to full democracy a rare exception. At the same time, a backlash led by the ruling elites against manipulation through business magnates makes a transition to full autocracy more likely than in competitive authoritarian regimes without influential business magnates.
Constructing fluid relationships through language: A study of address terms in a Japanese drama and its pedagogical implications
Authors: Yonezawa Yoko 
Published: November 2019

AbstractThis study investigates address practices among family members in a Japanese TV drama. It qualitatively analyses not only a speaker’s culturally normative use of address terms but also his/her deviations from the norm, including the use of terms that are atypical in Japanese communication. The study sheds light on dynamic aspects of interaction in Japanese in which the speaker creates meaning and constructs fluid relationships with other interlocutors through the use of address terms. The pedagogical implications of these findings are discussed, along with the value of using telecinematic discourse in teaching, to give learners of Japanese a socio-pragmatic understanding of address practices.
Suitability of FBG for Gain Flatness of 64 × 10 Gbps DWDM System Using Hybrid (EDFA+YDFA) Optical Amplifier in C + L Band up to 50 GHz (0.4 nm) Channel Spacing
Authors: Singh Harjit , Sheetal Anu 
Published: November 2019

Abstract
Gain flatness of erbium-doped fiber amplifier (EDFA) is an important aspect to support high speed multimedia applications for smart devices, cloud computing, big data analysis and high definition television (HDTV) as it achieves equal power for all dense wavelength division multiplexing (DWDM) channels. In this paper, we compare 32 and 64 channels 10 Gbps DWDM system using hybrid EDFA+ Ytterbium-doped silica fiber amplifier (YDFA) in C + L band for 0.4, 0.8 and 1.6 nm wavelength spacing along with FBG for gain flattening. The system performance has been analyzed in terms of optical signal to noise ratio and spectral gain fluctuation observed from the optical power spectrums. It is observed that YDFA although extends the amplification window of EDFA from 1530 to 1610 nm (C to L band), but gain fluctuates over the operating wavelength range. Gain flatness is enormously improved (5–10 dB) by adding FBG as a gain flattening filter to the hybrid (EDFA+YDFA) amplifier. It is found that as the channel spacing decreases (from 1.6 to 0.4 nm) and the number of channels increases (from 32 to 64), the gain reduces due to inter-channel crosstalk and four wave-mixing effect.
Shape-Based Analysis on Component-Graphs for Multivalued Image Processing

Published: November 2019

Abstract
Connected operators based on hierarchical image models have been increasingly considered for the design of efficient image segmentation and filtering tools in various application fields. Among hierarchical image models, component-trees represent the structure of grey-level images by considering their nested binary level-sets obtained from successive thresholds. Recently, a new notion of component-graph was introduced to extend the component-tree to any grey-level or multivalued images. The notion of shaping was also introduced as a way to improve the anti-extensive filtering by considering a two-layer component-tree for grey-level image processing. In this article, we study how component-graphs (that extend the component-tree from a spectral point of view) and shapings (that extend the component-tree from a conceptual point of view) can be associated for the effective processing of multivalued images. We provide structural and algorithmic developments. Although the contributions of this article are theoretical and methodological, we also provide two illustration examples that qualitatively emphasize the potential use and usefulness of the proposed paradigms for image analysis purposes.

Authors: Zhang Changgong , Hao Xuezhi 
Published: November 2019

Abstract

Background
The expression and significance of CD276 in non-small cell lung cancer (NSCLC) was explored.

Method
The BioGPS database was used to analyze the expression level of CD276 in normal tissues. Studies on the expression of CD276 in NSCLC patients using the Oncomine database. The prognostic roles of CD276 in NSCLC was studied using the Kaplan-Meier plotter database.

Result
The BioGPS database showed CD276 expression in all the human normal tissues. Compared with normal lung tissue, CD276 gene highly expressed in NSCLC tissue at mRNA level (P<0.05). The expression level of CD276 gene was negatively correlated with overall survival (OS) of NSCLC patients. Subgroup analysis showed that CD276 expression level had a significant effect on OS of patients with lung adenocarcinoma, while in squamous cell carcinoma its expression level had no significant effect on OS.

Conclusion
According to the information mined from the tumor gene database, CD276 mRNA was found highly expressed in NSCLC tissue and the expression of CD276 has a significant impact on survival of NSCLC patients, which provides an important theoretical basis for further study of the role of CD276 in the occurrence and development of NSCLC.

Published: November 2019

Abstract
Detailed characterization of the permeability and vascular volume of brain tumor vasculature can provide essential insights into tumor physiology. In this study, we evaluated the consistency of measurements in tumor blood volume and examined the feasibility of using ultrasmall superparamagnetic iron oxide (USPIO) versus gadolinium-diethylene triamine pentaacetic acid (Gd-DTPA) as contrast agents for MR perfusion imaging of brain gliomas in C6 Rats. Eighteen rats were intracerebrally implanted with C6 glioma cells, randomly divided into two groups and examined by 3.0T perfusion MR imaging with Gd-DTPA and USPIO. Tumor relative cerebral blood volume (rCBV) and relative maximum signal reduction ratio (rSRRmax) were created based on analysis of MR perfusion images. The mean values for rCBV were 2.09 and 1.57 in the USPIO and the Gd-DTPA groups, respectively, and rSRRmax values were 1.92 and 1.02 in the USPIO and the Gd-DTPA groups, respectively, showing signifi cant differences in both rCBV and rSRRmax between the USPIO and the Gd-DTPA groups (P < 0.05). The results showed that early vascular leakage occurred with gadolinium rather than USPIO in perfusion assessment, revealing that USPIO was useful in perfusion MR imaging for the assessment of tumor vasculature.

Published: November 2019

Abstract

Background
Clinically relevant potential drug-drug interactions are considered preventable adverse drug reactions.

Objective
The aim of this study was to ascertain the frequency of potential drug-drug interactions in acute ischemic stroke patients and to explore factors associated with occurrence of potentially contraindicated drug-drug interactions.

Methods
This observational retrospective cohort and nested case-control study was carried out among patients treated for acute ischemic stroke at the Neurological Intensive Care Unit in the Clinical Centre Kragujevac, Serbia. The potentially drug-drug interactions for each day of hospitalization were identifi ed using Micromedex® soft ware. Based on the existence or absence of potentially contraindicated drug-drug interactions, the participants were divided into a group of cases (n=111) and the control group (n=444).

Results
A total of 696 patients were analysed. All patients had a minimum of one potential drug-drug interaction during hospitalization. The most common drugs involved in potential drug-drug interactions were aspirin (8.02%), diclofenac (7.49%) and warfarin (7.14%). The number of medications prescribed for simultaneous use during hospitalisation and the use of antipsychotics in therapy signifi cantly increased the likelihood of potentially contraindicated drug-drug interactions aft er adjustment by means of logistic regression for 1.2 and 3 times, respectively.

Conclusions
This study suggests that patients with acute ischemic stroke are frequently exposed to potential drug-drug interactions. It is essential to identify potentially drug-drug interactions in these patients as early as possible in order to prevent adverse drug reactions and ensure safe recovery. Besides, full attention should be paid when adding each new medication in therapy, particularly when a neurologist decides to prescribe antipsychotics, such as risperidone.

Abstract

Introduction
Renal artery embolization is performed before radical nephrectomy (RN) for renal mass in order to induce preoperative infarction and to facilitate surgical intervention through decrease of intraoperative bleeding. Moreover, in metastatic renal cancer it seems to stimulate tumour-specific antibodies, even if no established benefits in clinical response or survival have been reported. The role of preoperative renal artery embolization (PRAE) in management of renal masses has been often debated and its real benefits are still unclear. Nevertheless, in huge and complex renal masses, which are often characterized by a high and anarchic blood supply and rapid local invasion, radical nephrectomy can be challenging even for skilled surgeons. The aim of this prospective randomized study was to evaluate the effectiveness and safety of PRAE in complex masses by comparing perioperative outcomes of RN with and without PRAE.

Materials and methods
From December 2015 to May 2018 we enrolled prospectively 64 patients who underwent RN for localized (T2a-b) or locally advanced (T3 and T4) or advanced (N+, M+) renal cancers. Patients were divided in two groups. The first group included 30 patients who underwent PRAE; in the second group we enrolled 34 patients who did not undergo RN without PRAE. Perioperative outcomes in terms of operative time, blood loss, transfusion rate and length of hospitalization were evaluated. Statistical analysis was performed using GraphPad Prism 6.0 software.

Results
Median blood loss was 250 ml (50-500) and 400 ml (50-1000) in the first and second group, respectively, with a statistically significant difference (p=0.0066). Median surgical time was 200 min (90-390) and 240 min (130-390) in PRAE and No-PRAE group (p=0.06), respectively. No major complications occurred after embolization. Overall complication rate in Group 1 and 2 was 46.7% (14/30) and 50% (17/34), respectively (p=0.34). No major complications occurred in both groups. The mean follow up was 21,5 months.

Conclusions
Our results prove PRAE to be a safe procedure with low complications rate. To our experience, PRAE seems to be a useful tool in surgical management of a large mass and advanced disease.
