Ultrafunctions and Generalized Solutions
Authors: Benci Vieri 
Published: March 2016

Abstract
The theory of distributions provides generalized solutions for problems which do not have a classical solution. However, there are problems which do not have solutions, not even in the space of distributions. As model problem you may think of

with Dirichlet boundary conditions in a bounded open star-shaped set. Having this problem in mind, we construct a new class of functions called ultrafunctions in which the above problem has a (generalized) solution. In this construction, we apply the general ideas of Non Archimedean Mathematics (NAM) and some techniques of Non Standard Analysis. Also, some possible applications of ultrafunctions are discussed.
Existence of Bound States for Schrödinger-Newton Type Systems
Authors: Vaira Giusi 
Published: March 2016

AbstractIn this paper we consider the following elliptic system in ℝ3where K(x), α(x) are non-negative real functions defined on ℝ3so that. When K(x) ≡ K∞and α(x) ≡ α∞we have already proved the existence of a radial ground state of the above system. Here, by using a new version of the moving plane method, we show that all positive solutions of the above system with K(x) ≡ K∞and a(x) ≡ α∞are radially symmetric and the linearized operator around a radial ground state is also non-degenerate. Using these results we further prove, under additional assumptions on K(x) and α(x), but not requiring any symmetry property on them, the existence of a positive solution for the system.

Authors: Wang Ying , Yang Jianfu 
Published: March 2016

Abstract
This paper is concerned with the following H’enon type problem

where B1(0) is the unit ball in ℝN centered at the origin, 1 < p, q and

if N ≥ 3. We show that there exists α∗ > 0 such that the ground state solution of the problem is non-radial if α > α∗. We also consider the limiting behavior of the ground state solution (u, v) as p + q → 2∗. We prove that the maximum points of two components u and v concentrate at the same point on the boundary ∂B1(0).

Authors: Kyritsi Sophia Th. , O’ Regan Donal , Papageorgiou Nikolaos S. 
Published: March 2016

Abstract
We consider nonlinear periodic problems driven by the scalar p-Laplacian with a Carathéodory reaction term. Under conditions which permit resonance at infinity with respect to any eigenvalue, we show that the problem has a nontrivial smooth solution. Our approach combines variational techniques based on critical point theory with Morse theory.

for 0 ≤ α < λ̅(Ω) and 1 < p ≤ n, and the supremum is infinity for α ≥ λ̅(Ω), where and ωn−1 is the surface area of the unit ball in ℝn. We also obtain the existence of the extremal functions for (0.2).
Nonlinear Problems with p(·)-Growth Conditions and Applications to Antiplane Contact Models
Authors: Boureanu Maria-Magdalena , Matei Andaluzia , Sofonea Mircea 
Published: March 2016

Abstract
We consider a general boundary value problem involving operators of the form div(a(·, ∇u(·)) in which a is a Carathéodory function satisfying a p(·)-growth condition. We are interested on the weak solvability of the problem and, to this end, we start by introducing the Lebesgue and Sobolev spaces with variable exponent, together with their main properties. Then, we state and prove our main existence and uniqueness result, Theorem 3.1. The proof is based on a Weierstrass-type argument. We also consider two antiplane contact problems for nonhomogenous elastic materials of Hencky-type. The contact is frictional and it is modelled with a regularized version of Tresca’s friction law and a power-law friction, respectively. We prove that the problems cast in the abstract setting, then we use Theorem 3.1 to deduce their unique weak solvability.

Authors: Furtado Marcelo F. , Silva Edcarlos D. , Silva Maxwell L. 
Published: March 2016

Abstract
We deal with the existence of nonzero solution for the quasilinear Schrödinger equation
−Δu + V(x)u − Δ(u2)u = g(x, u), x ∈ ℝN, u ∈ H1(ℝN),
where V is a positive potential and the nonlinearity g(x, s) behaves like K0(x)s at the origin and like K∞(x)|s|p, 1 ≤ p ≤ 3, at infinity. In the proofs we apply minimization methods.
Konzept eines wissensbasierten Frameworks zur Spezifikation und Diagnose von Inkonsistenzen in mechatronischen Modellen
Authors: Feldmann Stefan , Kernschmidt Konstantin , Vogel-Heuser Birgit 
Published: March 2016

Zusammenfassung
Inkonsistenzen, die im Engineering mechatronischer Systeme auftreten, können teuer werden – vor allem, wenn sie zu spät erkannt
werden. Die Herausforderung, Inkonsistenzen in den verschiedenen Modellen mechatronischer Systeme zu spezifizieren und zu
diagnostizieren liegt dabei vor allem in der Verschiedenartigkeit der Disziplinen. Folglich untersucht dieser Beitrag aus
wissenschaftlicher Sicht die Anforderungen an die Spezifikation und Diagnose von Inkonsistenzen und schlägt ein Konzept für ein
wissensbasiertes Framework vor. Hierzu werden Semantic Web Technologien eingesetzt, da diese sich aufgrund ihrer Flexibilität und
Erweiterbarkeit für den Einsatz in heterogenen Modellen besonders eignen. Anhand eines Anwendungsbeispiels werden die Erkenntnisse für
Praktiker illustriert und die Stärken und Limitationen eines solchen Ansatzes diskutiert.
Model based synthesis of automation functionality
Authors: Wagner Constantin , Kampert David , Schüller Andreas , Palm Florian , Grüner Sten , Epple Ulrich 
Published: March 2016

Abstract
The article demonstrates the advantages of meta-model-based solutions for multi-aspect automation tasks. Multi-aspect tasks require
solutions that consider information of multiple system aspects simultaneously. In today's practice, these aspects are maintained in
different tools which make implicitly use of tool-driven system models. In contrast, we propose to prioritize the models in order to
facilitate the handling of multi-aspect automation tasks. The article exemplifies this idea by introducing typical automation and
engineering models and illustrates their utility in a use-case example.
Does fiscal policy affect interest rates? Evidence from a factor-augmented panel
Authors: Dell’Erba Salvatore , Sola Sergio 
Published: March 2016

AbstractThis paper reconsiders the effects of fiscal policy on long-term interest rates employing a factor augmented panel (FAP) to control for the presence of common unobservable factors. We construct a real-time dataset of macroeconomic and fiscal variables for a panel of OECD countries for the period 1989–2013. We find that two global factors – the global monetary and fiscal policy stances – explain more than 60 percent of the variance in the long-term interest rates. Under our frame work, we find that the importance of domestic variables in explaining long-term interest rates is weakened. Moreover, the propagation of global fiscal shocks is larger in economies characterized by macroeconomic and institutional weaknesses.

Published: March 2016

AbstractAISI 316L stainless steel is commonly used as a low-cost material for permanent implants. It can be protected for degradation and corrosion by applying a hybrid silica based coating. Also the bioactive response of the implant can only be achieved by functionalizing the coated implant surface. The aim of this work is to synthesize and characterize a sol-gel made glass particles from the system SiO2-CaO-P2O5 with potential as bone inductive material, with and without an aging treatment of the precursor solution. The glass was synthesized by sol-gel technique that, comparing with melt glasses, generates an open net structure that could lead to particle dissolution and apatite deposition for biological purposes. The synthesized glass is dispersed by spray onto AISI 316L protected by a hybrid silica based coating, generating deposits with different size and morphology. To characterize the particles composition, microRaman spectroscopy was applied. It showed that no significant changes were reached after aging or thermal treatment of the deposited particles. Image processing techniques based on Mathematical Morphology were used to analyze morphology and sizes of the deposits obtain with the different sols (aged and no aged). Aproximately 50% of the surface was covered with particles made with a glass aged, and a 25% of covered area was reached with no aged one. When no aged glass particles were deposited, the particle size distribution shows the presence of many big particles with a roundness factor between 0.8 and 1 in a high percentage, meaning that they are spherical due to the presence of solvent and with a more open glass structure in the no aged glass. The Digital Image Processing and Raman spectroscopy tools help to analyze, characterize and quantify the bioactive particles deposited onto coated surgical grade stainless steel in terms of morphology, distribution and composition.
The problem with total error models in establishing performance specifications and a simple remedy
Authors: Krouwer Jan S. 
Published: March 2016

AbstractA recent issue in this journal revisited performance specifications since the Stockholm conference. Of the three recommended methods, two use total error models to establish performance specifications. It is shown that the most commonly used total error model – the Westgard model – is deficient, yet even more complete models fail to capture all errors that comprise total error. Moreover, total error models are often set at 95% of results, which leave 5% of results as unspecified. Glucose meter performance standards are used to illustrate these problems. The Westgard model is useful to asses assay performance but not to set performance specifications. Total error can be used to set performance specifications if the specifications include 100% of the results.
When do language comprehenders mentally simulate locations?
Authors: Liu Nian , Bergen Benjamin 
Published: March 2016

Abstract
Embodied approaches to comprehension propose that understanding language entails performing mental simulations of its content. The evidence, however, is mixed. Action-sentence Compatibility Effect studies (Glenberg and Kaschak 2002) report mental simulation of motor actions during processing of motion language. But the same studies find no evidence that language comprehenders perform spatial simulations of the corresponding locations. This challenges simulation-based approaches. If locations are not represented in simulation, but are still understood, then simulation may be unnecessary for understanding. We conducted a Location-sentence Compatibility experiment, to determine whether understanders mentally simulate locations. People did indeed simulate locations, but only when sentences used progressive (and not perfect) grammatical aspect. Moreover, mental simulations of locations differed for language about concrete versus abstract events. These findings substantiate the role of mental simulation in language understanding, while highlighting the importance of the grammatical form of utterances as well as their content.

Published: March 2016

Abstract
Bevacizumab was the first molecular-targeted antiangiogenic therapy approved for the treatment of metastatic colorectal cancer. Until now, there are no predictive biomarkers available to decide the prescription of bevacizumab in patients with colorectal cancer. The purposes of this review were to provide a critical appraisal of the evidence and to identify possible predictive genetic biomarkers. A literature search was performed to identify studies that determine different levels of treatment response between patients stratified according to defined biomarkers. Interesting findings were reported between patients stratified according to rs3025039 and rs833061 polymorphisms of the gene VEGFA, with statistically and clinically significant differences for progression-free survival and overall survival. However, another study conducted in a larger sample does not confirm these previous findings, suggesting that well-designed prospective studies are still needed to achieve conclusive results. FLT1 (or VEGFR1) rs9513070 seems to be an interesting candidate as a predictive biomarker, with differences of more than 10 months in OS between different patients groups. In our opinion, possible interesting biomarker candidates for future research could be the polymorphisms rs833061 and rs3025039 of VEGF-A, rs9513070 or haplotype analysis of FLT1, rs2661280 of RGS5, rs444903 and rs6220 of EGF and Ang-2 or LDH plasma levels.

Authors: Qi Feng , Guo Bai-Ni 
Published: March 2016

Abstract
In the paper, we establish necessary and sufficient conditions for two families of functions involving divided differences of the di- and tri-gamma functions to be completely monotonic. Consequently, we derive necessary and sufficient conditions for two families of functions involving the ratio of two gamma functions to be logarithmically completely monotonic. Furthermore, we deduce some inequalities for bounding the ratio of two gamma functions and divided differences of polygamma functions.

WE- and ELF-informed classroom practices: proposals from a pre-service teacher education programme in Italy
Authors: Vettorel Paola 
Published: March 2016

AbstractThe long-standing research in World Englishes (WE) and, more recently, in English as a Lingua Franca (ELF) has greatly contributed to problematizing several areas in connection to English Language Teaching, highlighting in particular the importance of teacher education as a first and fundamental step towards a more “inclusive” and “realistic” approach in ELT. A WE- and ELF-informed teacher education can indeed play a pivotal role in promoting awareness of the sociolinguistic and cultural changes brought about by the pluralization of English on the one hand, and of its function as a lingua franca on the other hand, and contribute to fostering a critical evaluation of ELT approaches, and materials, traditionally based on an Anglo-centric monolithic view of language and culture, taking account of different viewpoints in connection to the current modified reality of English. This paper will illustrate findings from an ongoing research study aimed at investigating trainee teachers’ beliefs concerning ELT pedagogic practices inclusive of the current pluralization of English. The study has been carried out with trainee teachers of English attending pre-service TFA (Tirocinio Formativo Attivo) and PAS (Percorso Abilitante Speciale) teacher education courses at the Department of Foreign Languages and Literatures, University of Verona, Italy, where part of the English Language course focused on issues related to WE, ELF and their pedagogical implications. By means of questionnaires and interviews, as well as class reflections and materials developed by the trainees as part of the course, the aim was to investigate to what extent a WE- and ELF-aware teacher education can contribute to expanding and/or modifying teachers’ awareness of the above issues in pedagogical terms. Findings related to the participants’ comments and practical proposals for the inclusion of WE- and ELF-informed activities in their teaching practices, as well as their critical reflections about problematic points, particularly in the local context and syllabi, will also be discussed.
Parallel Distance-Based Instance Selection Algorithm for Feed-Forward Neural Network
Authors: Fuangkhon Piyabute 
Published: March 2016

AbstractInstance selection endeavors to decide which instances from the data set should be maintained for further use during the learning process. It can result in increased generalization of the learning model, shorter time of the learning process, or scaling up to large data sources. This paper presents a parallel distance-based instance selection approach for a feed-forward neural network (FFNN), which can utilize all available processing power to reduce the data set while obtaining similar levels of classification accuracy as when the original data set is used. The algorithm identifies the instances at the decision boundary between consecutive classes of data, which are essential for placing hyperplane decision surfaces, and retains these instances in the reduced data set (subset). Each identified instance, called a prototype, is one of the representatives of the decision boundary of its class that constitutes the shape or distribution model of the data set. No feature or dimension is sacrificed in the reduction process. Regarding reduction capability, the algorithm obtains approximately 85% reduction power on non-overlapping two-class synthetic data sets, 70% reduction power on highly overlapping two-class synthetic data sets, and 77% reduction power on multiclass real-world data sets. Regarding generalization, the reduced data sets obtain similar levels of classification accuracy as when the original data set is used on both FFNN and support vector machine. Regarding execution time requirement, the speedup of the parallel algorithm over the serial algorithm is proportional to the number of threads the processor can run concurrently.

Antibiofilm and antifouling activities of extracellular polymeric substances isolated from the bacteria associated with marine gastropod Turbo sp
Authors: Viju Nadarajan , Satheesh Sathyaneson , Punitha Stanislaus Mary Josephine 
Published: March 2016

Abstract
The extracellular polymeric substances (EPS) produced by the bacteria associated with the gastropod Turbo sp. were isolated and screened for antibacterial activity against biofilm-forming bacteria. EPS of five out of 13 strains showed inhibitory activities in the antibacterial assay. Furthermore, the antibiofilm and antifouling activity of the most active EPS isolated from the strain KT1 was studied using various in vitro and in vivo bioassays. Results revealed that EPS significantly inhibited the growth and biofilm formation of bacteria. Furthermore, the antifouling coating developed with bacterial EPS considerably reduced the recruitment of fouling organisms on coated surfaces submerged in the seawater. The functional groups present in EPS, characterized by strong activity, were analyzed using FT-IR and the spectrum showed the presence of alcohol, amines, carboxylic acid and esters. The bacterium responsible for the production of bioactive EPS was identified as Pseudomonas aeruginosa, using the 16S rRNA gene. Since the findings of this study revealed the antibiofilm and antifouling activities of EPS, further long term field tests and characterization of the bioactive compound of the EPS could lead to the development of eco-friendly antifouling coating.

Abstract
The first comprehensive meiobenthos study was carried out in Turkey, the Southern Black Sea (Sinop) from August 2009 to July 2010.Sediment samples were collected monthly at eight stations at 3 m and 10 m water depths located on four transects. A metal push core sampler (surface area 12.56 cm2 and length 10 cm was used to obtain the material. Meiofaunal abundance and composition were examined. The results revealed that the meiofaunal community consists of twenty five higher taxonomic groups. Four groups dominated the community; Nematoda, Harpacticoida, Foraminifera and Polyuchaeta. Spatial and temporal meiofaunal abundance fluctuated among stations and over time.
Some Thoughts on the Spatial Forms and Practices of Storytelling
Authors: Bieger Laura 
Published: March 2016

Abstract
Our notions of space and place are deeply invested with narrative – to the degree that one can think of storytelling as a spatial form and practice. Critical engagements with space and place have bypassed these investments so far since narrative is firmly associated with matters of time whereas space, commonly perceived as the stable backdrop to history’s transformative operations, is yet to be emancipated from the dominance of time. Parallel to reconstructing space in ways that bring out its own productivity, narratologists have been reassessing narrative’s vastly neglected relation to space. This essay zooms in on two venues of this work: on general recalibrations of the relation of space and narrative, and on the spatial metaphors evoked and employed by it. Linking these reassessments of narrative spatiality to on-going revisions of representational narrativity, I hope to show how these parallel strands of critical rethinking can deepen our understanding of both space and narrative – if they are brought to converge.
