Monocytes isolated by positive and negative magnetic sorting techniques show different molecular characteristics and immunophenotypic behaviour
Authors: Bhattacharjee Jashdeep , Das Barun , Mishra Alaknanda , Sahay Preeti , Upadhyay Pramod 
Published: December 2017

Background: Magnetic sorting of cells, based on microbead conjugated antibodies (Abs), employs positive as well as negative immunomagnetic separation methods, for isolation of a specific cell population. These microbeads are suggested to be nontoxic, biodegradable carriers conjugated to various antibodies. Isolation of cells through positive selection involves the attachment of antibody conjugated microbeads to the cells of interest, followed by their isolation in the presence of a strong magnetic field to obtain higher purity. Negative selection involves attachment of microbead conjugated antibodies to all other cell populations except the cells of interest, which remain untagged. In the present study, we compared the two methods for their effect on functional and immunophenotypic behavior of isolated CD14+ monocytes.Methods: Peripheral blood mononuclear cells (PBMCs) were isolated from blood collected from healthy volunteers by density gradient centrifugation. Human blood derived monocytes were isolated through positive selection and negative selection, making use of the appropriate monocyte isolation kit. Monocytes were then stimulated with lipopolysaccharide (LPS) and their activation and proliferation capacity were examined. The degradation or dissociation of cell-bound microbeads was also investigated.Results: We observed an impaired LPS sensitivity as well as poor activation and proliferation capacity upon stimulation by LPS in positively sorted CD14+ monocytes as compared to negatively sorted CD14+ monocytes. The attached microbeads did not degrade and remained attached to the cells even after 6 days of culture.Conclusions: Our results suggest that positively sorted CD14+ cells exhibit hampered functionality and may result in inaccurate analysis and observations in downstream applications. However, these cells can be used for immediate analytical procedures.
Dynamic Pricing Under Debt: Spiraling Distortions and Efficiency Losses
Authors: Besbes Omar , Iancu Dan A. , Trichakis Nikolaos 
Published: December 2017

Firms often finance their inventory through debt and subsequently sell it to generate profits and service the debt. Pricing of products is consequently driven by inventory and debt servicing considerations. We show that limited liability under debt induces sellers to charge higher prices and to discount products at a slower pace. We find that these distortions result in revenue losses that compound over time, leading to some form of performance spiral down. We quantify the extent to which these inefficiencies can be mitigated by practical debt contract terms that emerge as natural remedies from our analysis, and find debt amortization or financial covenants to be the most effective, followed by debt relief and early repayment options.

If at first you don’t succeed, rip it out and try again: The benefits of failure among DIY handcrafters
Authors: Stalp Marybeth C. , Winge Therèsa M. 
Published: December 2017

Abstract
Failure is a vital part of the creative process – we learn through failure. However, within the current culture that publicly celebrates success and achievement (sometimes at all costs) people are often hesitant to admit their failures – failure has become not just something to experience, but a negative and stigmatizing label, something to be avoided at all costs. Because of this, our ‘congratulatory culture’ reduces the importance of the creative process (including failure), especially in creative work. In this article, we focus on people who encounter failure regularly. We study people who make things with their hands – Do-It-Yourself (DIY) handcrafters who work with fibres and textiles. In our qualitative interview study with 44 North American handcrafters (e.g. those engaged in leisure weaving, knitting, crochet, patchwork), we examine ‘failure’, how handcrafters discuss the importance of failure, and how failure fits importantly into the creative process. We present discourse offered by the studies of the creative process and the importance of ‘failure’, as well as firsthand examples from our research and ethnographic experiences. We explore the complex creative process, including simultaneously positive and negative experiences.
Somatics herstories: Tracing Elsa Gindler’s educational antecedents Hade Kallmeyer and Genevieve Stebbins
Authors: Mullan Kelly Jean 
Published: December 2017

Abstract
This article explores origin stories within the field of Somatics and attempts to dispel some myths about the early work of the German somatic pioneer Elsa Gindler while also paying homage to teachers who preceded her. Based on my translations of German literature, new information about the Harmonic Gymnastics system that Elsa Gindler was certified to teach is provided. Developed by the American dancer and movement educator Genevieve Stebbins, Harmonic Gymnastics had a large impact on Gindler when her teacher Hade Kallmeyer brought the work to Germany. There is little commonly known about the heritage of Harmonic Gymnastics; therefore, this article hopes to illuminate Stebbins’ work. Genevieve Stebbins also acted as an inspiration to the American dance pioneers Ruth St. Denis and Isadora Duncan, hence, this article also touches upon Stebbins’ influence within the advent of American modern dance.
A gallery of hanging thoughts: On solo choreography (an artist’s perspective on mentoring post-graduate students)
Authors: Nunan Mary 
Published: December 2017

Abstract
The article is intended to evoke a three-dimensional space in which some framed thoughts and reflections, on the process of creating solo choreographies, hang. The reader is invited to move through the gallery – to engage with the frames and with the spaces between them. The frames provide for experiences of solo making to be viewed from a number of perspectives. My stance as a writer and mentor is at times personal/intimate and at times more formal/distanced. It moves between both, weaving in the voices of other artists, scholars and students, all of whom I have found to be inspiring in their ability to clearly articulate their experience of some of the most delicate and subtle, as well as practical and logical, aspects of creating new work.
Eje 1. Documentales, actores, personajes y circuitos de circulación: Algo más que filmes para la Corona. John Grierson y el Movimiento Documental Británico
Authors: Campo Javier 
Published: December 2017

El primer movimiento cinematográfico en la historia del cine documental fue uno de los más controversiales, inasibles y malinterpretados de todos. El Movimiento Documental Británico, surgido al amparo de instituciones estatales, fue justamente definido más corrientemente por su vinculación con los intereses de la Corona y el gobierno inglés que por su aporte al desarrollo del cine documental durante sus primeros veinte años de vida.En buena medida las manifestaciones de los realizadores protagonistas de esta historia (y no las representaciones configuradas por los mismos) otorgaron materia a las malas interpretaciones posteriores. Pero en este estudio incluiremos lo que pocos: las películas. Es allí en donde los estudios sobre el Movimiento Británico no se pararon más que circunstancialmente. Es allí también en donde encontraremos los elementos que nos permitirán superar el umbral de «lo pedagógico institucional» de este conjunto de filmes para recuperar la real envergadura de los trabajos de Grierson y sus muchachos. Es allí en donde, por último, como dice Brian Winston: «Grierson y sus seguidores pusieron los problemas sociales con una puesta “poética”» (1995:55).

Published: December 2017

<p class="p1"><span class="s1"> </span>Dry electrodes, which have an array of vertically aligned conducting micro-needles over a conducting substrate/base are most suitable for long-term continuous monitoring of EEG-signal, and overcomesthe disadvantages of conventional wet electrodes. A crucial design requirement for thesemicro-needlearrays, is the choice of the needle material with suitable mechanical strength to penetrate the skin without mechanical failure. This paper gives, the results of mechanical failure analysis of different needle materials that have been typically used/proposed for invasive use. A conical needle with 150μ width at the base and 10μ width at the tip, and length in the range 10μ - 200μ was taken up for calculation. The Critical load for failure, falls in the following descending order for the selected materials: viz., Carbon Nanofibre (CNF), Titanium-alloy (Ti 6-4), Single Crystal Silicon, Nickel, Tungsten, Platinum-Iridium (Pt90 percent-Ir10 percent), Stainless Steel (SS304),Poly Methyl Methacrylate (PMMA), Polyimide, Polycarbonate, Gold, Silver, Photoresist-SU8, Polyurethane and Poly DiMethylSiloxane (PDMS).Taking the most accepted value of 0.1N as the penetration force required for needle penetration into skin, it is seen that for a needle length of 100μ, the following materials, Carbon Nanofibre (CNF), Titanium-alloy (Ti 6-4), Single Crystal Silicon, Nickel, Tungsten, Platinum -Iridium (Pt90 percent-Ir10 percent) andStainless Steel (SS304), can penetrate the skin without mechanical failure.</p>

<p>Every country is engaging its armed forces in different terrain and climatic conditions to protectsovereignty and manage internal conflict. During peace / wartime conflicts, the soldiers are subjected toextremeenvironmental conditions. These extreme, hostile, non-habitable conditions exert a toll on the soldiers’ performance and also pose threat to theirlife. Airmen are prone to be exposed to low pressures, high altitude, and hypoxic conditions. Similarly,a Mariner is exposed to high pressuresand hydro environment. Land soldiers are deployed in various terrain having myriadenvironmental conditions such ashigh temperature in deserts, subzero cold conditions in the high mountains andvarying range of difficulties encountered in forested hilly terrain.In addition to these adverse conditions, soldiers also need to counter theconflicts from neighboring / enemy countries. It is paramount that, these soldiers are protected from all these adverse extreme environmental conditions. </p>

Connecting the clinical IT infrastructure to a service-oriented architecture of medical devices
Authors: Andersen Björn , Kasparick Martin , Ulrich Hannes , Franke Stefan , Schlamelcher Jan , Rockstroh Max , Ingenerf Josef 
Published: December 2017

AbstractThe new medical device communication protocol known as IEEE 11073 SDC is well-suited for the integration of (surgical) point-of-care devices, so are the established Health Level Seven (HL7) V2 and Digital Imaging and Communications in Medicine (DICOM) standards for the communication of systems in the clinical IT infrastructure (CITI). An integrated operating room (OR) and other integrated clinical environments, however, need interoperability between both domains to fully unfold their potential for improving the quality of care as well as clinical workflows. This work thus presents concepts for the propagation of clinical and administrative data to medical devices, physiologic measurements and device parameters to clinical IT systems, as well as image and multimedia content in both directions. Prototypical implementations of the derived components have proven to integrate well with systems of networked medical devices and with the CITI, effectively connecting these heterogeneous domains. Our qualitative evaluation indicates that the interoperability concepts are suitable to be integrated into clinical workflows and are expected to benefit patients and clinicians alike. The upcoming HL7 Fast Healthcare Interoperability Resources (FHIR) communication standard will likely change the domain of clinical IT significantly. A straightforward mapping to its resource model thus ensures the tenability of these concepts despite a foreseeable change in demand and requirements.
Estimation of the Time-Dependent Body Force Needed to Exert on a Membrane to Reach a Desired State at the Final Time
Authors: Boyadjiev Lyubomir , Rashedi Kamal , Sini Mourad 
Published: December 2017

Abstract
We are concerned with the wave propagation in a homogeneous 2D or 3D membrane Ω of finite size. We assume that either the membrane is initially at rest or we know its initial shape
(but not necessarily both) and its boundary is subject to a known boundary force.
We address the question of estimating the needed time-dependent body force to exert on the membrane to reach
a desired state at a given final time T. As an additional information, we ask for
the displacement on the boundary. We consider the displacement either at a single point of the boundary or on the whole boundary.
First, we show the uniqueness of solution of these inverse problems under natural conditions on the final time T. If, in addition, the displacement on the whole boundary is only time dependent (which means that the boundary moves with a constant speed), this condition on T is removed if Ω satisfies Schiffer’s property.
Second, we derive a conditional Hölder stability inequality for estimating such a time-dependent force. Third, we propose a numerical procedure based on the application of the satisfier function along with the standard Fourier expansion of the solution to the problems. Numerical tests are given to illustrate the applicability of the proposed procedure.
Computational Fluid Dynamics calculation of a planar solid oxide fuel cell design running on syngas
Authors: Pianko-Oprych Paulina , Zinko Tomasz , Jaworski Zdzisław 
Published: December 2017

Abstract
The present study deals with modelling and validation of a planar Solid Oxide Fuel Cell (SOFC) design fuelled by gas mixture of partially pre-reformed methane. A 3D model was developed using the ANSYS Fluent Computational Fluid Dynamics (CFD) tool that was supported by an additional Fuel Cell Tools module. The governing equations for momentum, heat, gas species, ion and electron transport were implemented and coupled to kinetics describing the electrochemical and reforming reactions. In the model, the Water Gas Shift reaction in a porous anode layer was included. Electrochemical oxidation of hydrogen and carbon monoxide fuels were both considered. The developed model enabled to predict the distributions of temperature, current density and gas flow in the fuel cell.
The influence of supercritical foaming conditions on properties of polymer scaffolds for tissue engineering
Authors: Kosowska Katarzyna , Henczka Marek 
Published: December 2017

Abstract
The results of experimental investigations into foaming process of poly(ε-caprolactone) using supercritical CO2 are presented. The objective of the study was to explore the aspects of fabrication of biodegradable and biocompatible scaffolds that can be applied as a temporary three-dimensional extracellular matrix analog for cells to grow into a new tissue. The influence of foaming process parameters, which have been proven previously to affect significantly scaffold bioactivity, such as pressure (8-18 MPa), temperature (323-373 K) and time of saturation (1-6 h) on microstructure and mechanical properties of produced polymer porous structures is presented. The morphology and mechanical properties of considered materials were analyzed using a scanning electron microscope (SEM), x-ray microtomography (μ-CT) and a static compression test. A precise control over porosity and morphology of obtained polymer porous structures by adjusting the foaming process parameters has been proved. The obtained poly(ε-caprolactone) solid foams prepared using scCO2 have demonstrated sufficient mechanical strength to be applied as scaffolds in tissue engineering.
An accurate Kriging-based regional ionospheric model using combined GPS/BeiDou observations
Authors: Abdelazeem Mohamed , Çelik Rahmi N. , El-Rabbany Ahmed 
Published: December 2017

AbstractIn this study, we propose a regional ionospheric model (RIM) based on both of the GPS-only and the combined GPS/BeiDou observations for single-frequency precise point positioning (SF-PPP) users in Europe. GPS/BeiDou observations from 16 reference stations are processed in the zero-difference mode. A least-squares algorithm is developed to determine the vertical total electron content (VTEC) bi-linear function parameters for a 15-minute time interval. The Kriging interpolation method is used to estimate the VTEC values at a 1 ° × 1 ° grid. The resulting RIMs are validated for PPP applications using GNSS observations from another set of stations. The SF-PPP accuracy and convergence time obtained through the proposed RIMs are computed and compared with those obtained through the international GNSS service global ionospheric maps (IGS-GIM). The results show that the RIMs speed up the convergence time and enhance the overall positioning accuracy in comparison with the IGS-GIM model, particularly the combined GPS/BeiDou-based model.
On Kierkegaard’s Reaction to H.N. Clausen
Authors: Suto Takaya 
Published: December 2017

AbstractThe purpose of this article is to rethink the relationship between Kierkegaard and the Enlightenment by looking at his reaction to Henrik Nicolai Clausen (1793-1877). Certainly, Kierkegaard did not display a historical-critical study of theology in his authorship such as that of Clausen, but nevertheless we can trace a line that runs from Clausen to Kierkegaard that tracks their strong focus and emphasis on the New Testament, self-appropriation, works after inner faith, critique of speculation, the limits of historical research and the positivity of Christianity. For Kierkegaard, Clausen was an important figure in revising the understanding of Christianity in 19th-century Denmark.
Comparative FEM Analysis of Gears Modeled With Analytical, Solid Subtracting and Mixed CAD Generating Method
Authors: Tolvaly-Rosca Ferenc , Kakucs András , Forgó Zoltán , Máté Márton 
Published: December 2017

Abstract
The paper proposes a comparative FEM analysis of gears solid model bodies, obtained with three different methods. The analytical method is based on the mathematical equations of the tooth flanks. It supposed to be the most accurate and precise solid modeling process. However, it reveals it’s limits by handling of surfaces that are not deduced mathematically, or in case of tooth geometries which needs to be modified in order to perform a quick test regarding the probably effects of the mentioned modifications. The solid subtraction- and the newly developed, mixed CAD method are pure CAD generating methods. As any discrete generating method, their precision is influenced by the fineness of the iteration steps. In case of the mixed CAD solution the precision is influenced by the filtering algorithm applied to the generated Points Cloud. The visual comparison of the three mentioned methods, was presented in previously published papers. The present paper validates the novel mixed CAD method comparing the FEA analysis of the generated solid models.
Convergence results for a family of Kantorovich max-product neural network operators in a multivariate setting
Authors: Costarelli Danilo , Vinti Gianluca 
Published: December 2017

AbstractThe theory of multivariate neural network operators in a Kantorovich type version is here introduced and studied. The main results concerns the approximation of multivariate data, with respect to the uniform andLpnorms, for continuous andLpfunctions, respectively. The above family of operators, are based upon kernels generated by sigmoidal functions. Multivariate approximation by constructive neural network algorithms are useful for applications to neurocomputing processes involving high dimensional data. At the end of the paper, several examples of sigmoidal functions for which the above theory holds have been presented.

Abstract
Topologies of special type in a product of two topological spaces are introduced and considered here, in a general case, then in ℝ
n
to finish on the plane. In the last case, the graph of any function is closed in the considered topology, so it leads to interesting examples of open sets. Our purpose is to study properties of these topologies and connections between them. We prove also that every continuous real function from the plane equipped with the considered topology is in the first class of Baire.
