Parameter identification for the linear wave equation with Robin boundary condition
Authors: Bacchelli Valeria , Pierotti Dario , Micheletti Stefano , Perotto Simona 
Published: May 2018

Abstract
We consider an initial-boundary value problem for the classical linear wave equation,
where mixed boundary conditions of Dirichlet and Neumann/Robin type are enforced at the endpoints of a bounded interval.
First, by a careful application of the method of characteristics, we derive a closed-form representation
of the solution for an impulsive Dirichlet data at the left endpoint, and valid for either a Neumann or a Robin
data at the right endpoint. Then we devise a reconstruction procedure for identifying both the interval length and
the Robin parameter. We provide a corresponding stability result and verify numerically its performance moving
from a finite element discretization.
Proximization and literature: Marquez’s “a very old man with enormous wings”
Authors: Farsi Roghayeh 
Published: May 2018

AbstractThis paper applies the politics-based theory of Discourse Space to a literary text in order to investigate its flexibility and possible contribution to literary interpretation. As a case study, Gabriel Garcia Marquez’s short story, “A very old man with enormous wings” has been selected; this story most obviously evolves out of dichotomies on both inter- and intra-character levels. The theory’s proximization model is the main core of the analysis based on which the role of the deictic centre in positioning the story’s entities is accentuated. The analysis shows that despite its advantages, the proximization model needs to be expanded in order to accommodate the variety of deictic centres which any literary text, unlike political discourse, has. A comparison between Discourse Space Theory and narratology shows the inadequate attention the latter assigns to the axiological and evaluative role of the deictic centre in the story.

Abstract

Background:
The receptor for advanced glycation end products (RAGE) has a critical role in the pathogenesis of inflammation. In healthy children, its basal expression on the peripheral blood mononuclear cell (PBMC) and the basal circulating soluble RAGE (sRAGE) levels are unknown. The aim of this study was to describe both.

Methods:
This is a monocentric, observational and descriptive study of samples obtained from healthy children. The RAGE expression on PBMC was analyzed using flow cytometry. The sRAGE values were determined with a specific sandwich enzyme-linked immunosorbent assay (ELISA) kit, later the relation between cellular RAGE and sRAGE was described.

Results:
Forty-three children were included. The median sRAGE level was 849.0±579.0 pg/mL. The RAGE mean fluorescence intensity (MFI) was 1382±506 in monocytes and 792±506 in lymphocytes. There were no differences between genders. A negative correlation was found between sRAGE and RAGE MFI in lymphocytes (r=−0.3; p=0.04).

Conclusions:
We describe for the first time the RAGE surface levels on PBMC in children. It showed a negative correlation with sRAGE. The sRAGE circulating level is lower than the sRAGE level described in adult population or non-healthy children. Our findings should be confirmed in order to apply them as reference values for future investigations.
Subordinate and interrogative clause negation in Iquito
Authors: Hansen Cynthia 
Published: May 2018

AbstractThis paper describes a specific non-standard negation strategy in Iquito, a moribund Zaparoan language spoken in northern Peruvian Amazonia. This strategy is used in finite subordinate clauses (namely adverbial dependent clauses and relative clauses), as well as information questions, and it utilizes two negative markers: a negative particle which is also found in standard negation, and a verbal affix which does not function as a negator in any other context. Using existing typological characterizations of subordinate clause negation, we see that Iquito exhibits the following attested traits: it uses the standard negator in a different position, it also utilizes a distinct negator, and it employs more negators in the subordinate clause than in the main clause. But unlike the languages presented in the literature, Iquito utilizes these parameters simultaneously. Additionally, the position of the standard negator changes within the subordinate clause, depending on the reality status of the clause. Using Iquito as a case study, I propose a set of parameters for comparing subordinate clause and interrogative negation strategies to standard negation strategies, which include the type of negator used, its position, the overall number of negators, the potential for interaction with other grammatical categories, such as reality status, and the resulting word order of the clause. This set of parameters expands the initial typological characterizations of subordinate clause negation strategies.
The conservation status of a poorly known range-restricted mammal, the Nimba otter-shrewMicropotamogale lamottei

Published: May 2018

AbstractWe have a poor understanding of the ecology of many African small mammals due to a lack of basic research. This has important conservation implications, particularly for range-restricted species in tropical regions. In this study, we provide new insight into the distribution and ecology of one such species, the Nimba otter-shrew (Micropotamogale lamotteiHeim de Balsac 1954). We apply niche and occupancy modeling to inform on the range and habitat use of this semi-aquatic species. We estimate that its global range [extent of occurrence (EOO)] is 14,725 km2. Using occupancy modeling, we show that mining has a direct impact on the occurrence of this species. We also provide preliminary observations of its movements through radio-tracking. Using maximum entropy (Maxent) modeling, we identify the North Lorma National Forest and the Wonegizi range (northern Liberia) that appear suitable for this species, but where it has not yet been recorded. We suggest that the Nimba otter-shrew has a global distribution centered on the Mount Nimba region, straddling the borders of Liberia, Guinea and Côte d’Ivoire, and that it requires urgent conservation attention to ensure its long-term persistence. Finally, we provide evidence to support an uplisting of its IUCN Red List conservation status to Vulnerable.
An Integrated Throughflow Method for the Performance Analysis of Variable Cycle Compression Systems
Authors: Liu Baojie , Jia Shaofeng , Yu Xianjun 
Published: May 2018

AbstractA streamline curvature method based integrated throughflow analysis approach is newly developed to deal with component matching problems of variable cycle compression systems. The construction of variable cycle compression system is modularly modelled in the procedure. Splitting and confluent flow are elaborately disposed. A numerical method based on the “streamline floating” character of streamline curvature method is developed to model the function of forward variable area bypass injector. Moreover, extensive models used in the throughflow calculations, including minimum loss incidence, deviation and loss models were assessed, selected and modified. Finally, code validations were conducted on three representative traditional compressors, i. e. NASA rotor 67, NASA stage 37 and a custom-designed low-speed repeating four-stage compressor. Both the predicted overall characteristics and spanwise profiles agree reasonably well with the experimental data. The validated procedure was finally used to sketch the performance maps of a double bypass compression system under two different control rules, i. e. the first bypass throttling and the second bypass throttling. The results show some aspects of the difficulties and complications in operating a variable cycle compression system, and meanwhile, demonstrate the superiority of the newly developed integrated throughflow method.
Herausforderungen bei der Messung von Wohlfahrt
Authors: Jochimsen Beate , Raffer Christian 
Published: May 2018

Zusammenfassung:Initiiert von einer lebhaften öffentlichen und wissenschaftlichen Debatte um die Eignung des Bruttoinlandsprodukts als Indikator für materiellen Wohlstand sind zahlreiche alternative Maße zur Wohlstands- und Wohlfahrtsmessung entwickelt worden. Fällt dabei die Wahl auf einen Indikatorensatz, ist die Bestimmung der optimalen Anzahl der Indikatoren eine zentrale Herausforderung. Je mehr Indikatoren ausgewählt werden, desto besser können zwar die Bestandteile der Wohlfahrt abgebildet werden, desto schlechter ist aber die Kommunizierbarkeit. Beate Jochimsen und Christian Raffer analysieren mit Hilfe mehrerer statistischer Methoden die Verbindungen der 10 W³-Leitindikatoren des Deutschen Bundestages untereinander. Es zeigt sich, dass bis zu vier dieser Indikatoren ohne großen Informationsverlust weggelassen werden können, da sie mit den verbleibenden eng korreliert sind. Ein kleinerer W³-Indikatorensatz könnte wesentlich leichter erklärt und kommuniziert werden. Im Ergebnis bedeutet dies, dass der Umfang aller, nationaler und internationaler, Indikatorensätze zur Wohlfahrtsmessung kritisch zu würdigen ist.
Synchronisation and Circuit Realisation of Chaotic Hartley System

Published: May 2018

Abstract
Hartley chaotic system is topologically the simplest, but its dynamical behaviours are very rich and its synchronisation has not been seen in literature. This paper aims to introduce a simple chaotic system which can be used as alternative to classical chaotic systems in synchronisation fields. Time series, phase portraits, and bifurcation diagrams reveal the dynamics of the mentioned system. Chaotic Hartley model is also supported with electronic circuit model simulations. Its exponential dynamics are hard to realise on circuit model; this paper is the first in literature that handles such a complex modelling problem. Modelling, synchronisation, and circuit realisation of the Hartley system are implemented respectively in MATLAB-Simulink and ORCAD environments. The effectiveness of the applied synchronisation method is revealed via numerical methods, and the results are discussed. Retrieved results show that this complex chaotic system can be used in secure communication fields.
Experimental and Theoretical Study on the Interaction of P-Aminophenol Hydrochloride with H2O
Authors: Hou Bingbing , Peng Peng , Zhang Ping , Zhai Cuiping 
Published: May 2018

Abstract
UV-Vis absorption spectra, cyclic voltammetry and 1H nuclear magnetic resonance (1H NMR) spectra were applied to explore the hydrogen bond interactions of p-aminophenol hydrochloride (PAH) with H2O. The results indicated the hydrogen bonds were formed in PAH–H2O system. The anodic/cathodic peak potentials and UV-Vis absorption bands of PAH in H2O could be affected due to the interactions. The results of density functional theory, atoms in molecules theory and natural bond orbital analyses further confirmed the existence of hydrogen bonds between the phenolic hydroxyl, –NH3
+ protons and Cl− of PAH and H2O. Furthermore, the π-π stacking was suggested between PAH benzene rings from the 1H NMR spectra at higher concentrations.

Gift giving is psychologically and culturally complex. In any context, a gift can have multiple meanings. In the context of the doctor-patient relationship, the giving of gifts and decisions about whether to accept gifts raise complex ethical issues. In this essay, a number of pediatric oncologists discuss the ethical considerations that should guide physicians as they decide how to respond to an extravagant gift from a family.
Diagnostics as prevention — a rapid testing-based strategy of sex workers against sexual HIV exposure

Published: May 2018

Introduction: German sex workers have illegally established a prevention strategy, which consists of testing potential sexual partners with human immunodeficiency virus (HIV)-specific rapid diagnostic tests (RDTs) prior to engaging in unprotected sexual intercourse eventually performed in case of a negative test result. Based on a recently established modeling approach, the effectiveness of this strategy regarding the risk of HIV exposure was compared with protection provided by condom use.
Methods: Based on a literature search, the following assumptions were used for the calculations: an averaged 80% exposure risk reduction with a condom used during sexual intercourse, usage of a well-characterized 4th-generation HIV RDT, and a 10 day post-infection period without any measurable viral load in peripheral blood followed by a seroconversion period of about 3 weeks with 12.3% test sensitivity (antigen-specific) and only afterwards 97.3% (antibody-specific) test sensitivity.
Results: In most constellations, the HIV exposure risk in case of RDT-based prevention was lower than with condom use.
Conclusions: The RDT-based HIV exposure prevention as established by sex workers is effective in most situations. A notable weakness of the strategy is the RDTs' poor sensitivity in spite of a high transmission risk during the seroconversion stage.
Struggling to Fit in. The Dutch in a Transnational Army, 1936–1939
Authors: Kruizinga Samuël 
Published: May 2018

Struggling to Fit In. The Dutch in a Transnational Army, 1936-1939 The Spanish Civil War (1936–1939) possessed a transnational resonance that echoed far beyond the borders of the country in which it was fought. It drew thousands of foreign fighters to Spain where, as many believed, the future of Europe would be decided. Most of them fought on the side of the embattled Republican government against an uprising supported by international Fascism. Given the foreign fighters’ similar socio-economic backgrounds and shared anti-Fascist sentiment, historians have suggested that the «International Brigades», formed out of these foreign fighters, constitute a true transnational army. This article suggests, however, that many of these foreign fighters had real trouble forging a transnational connection with their fellow fighters. Focusing on Dutch Interbrigadiers, it further highlights how the specificities of Dutch political culture and the legal regime created in the Netherlands combined to create a unique set of circumstances that impeded Dutch foreign fighters’ abilities to effectively work together with their German colleagues in Spain and their post-Spanish Civil War efforts to resist the Nazi occupation of the Netherlands. This article suggests, therefore, that the International Brigades do not possess a single, distinctive and collectively transnational identity. Rather, they are made up of different identity layers that can, but need not, be mutually exclusive, and are linked to elements of different national and/or military cultures.
Collaboration and Resistance in Wartime Poland (1939–1945) – A Case for Differentiated Occupation Studies
Authors: Böhler Jochen , Młynarczyk Jacek Andrzej 
Published: May 2018

Collaboration and Resistance in Wartime Poland (1939-1945) - A Case for Differentiated Occupation Studies This article aims to diffenenciate the often simplistic depiction of war and occupation in Europe between 1939 and 1945 as a fight of good against evil. Such a description can be found not only in popular culture, but also, though less blatantly, in historical literature. Without questioning the overall responsibility of the Axis powers for the horrendous crimes committed during the war, this article argues for a more nuanced approach that takes into account the often complex nature of interaction between the occupiers and the occupied. Instead of invoking moral judgment, the authors aim to prioritize the historical analysis of the reality of Poland's occupation by the Nazis, recognizing that the parties involved had their own agency and often conflicting agendas. The authors apply this approach to two major phenomena: collaboration with, and resistance against the occupying forces. It thereby becomes clear that violence was exchanged not only between the occupants and the occupied, but also between different political and ethnic groups of the Polish society.

The perspective of young people as co-researchers has recently increased as a participatory framework of study in several fields of inquiry. The focus has mostly been on empowering the youth instead of methodological perspective which is the focus in this arts-based pedagogical study on youth documentary theatre as an action research. The objective of the text is to describe how the integrated practices of research and documentary theatre support youth as co-researchers.The article is based on a youth documentary theatre implemented in 2016 as a case example. Seven 17–28-year-old youngsters were invited to make theatre as co-researchers and as informants of their own life course, especially in-between the stages of schooling. The research material consists of multiple data, for example, research diary of the director, interviews, the verbatim theatre piece and the documented five live performances including audience feedback.Results show that documentary theatre can function as a research team, following the collective praxis method in which the youth co-research is supported by director’s choices implementing equal partnerships. Director’s role is a facilitator giving freedom and space to the youth’s decisions on the narrative and play. This is the way for more robust insider knowledge as well.How cultural policies and research are taking into account youth agency? Dignifiying youth is offered as a conclusion. In institutions like theatre, inclusive youth pedagogies and forms of directing are suggested, taking youth as co-artists together with professional adults. This applies to youth research as well.
