Paramedic views on clinical research in cardiac arrest
Authors: Rhys Megan , Voss Sarah , Davies Sian Emma , Coates Dave , Benger Jonathan 
Published: May 2018

Background: The success of pre-hospital research relies on positive engagement from paramedics. Without adequate participation and protocol compliance, trials will not succeed. Aims: The aims of the current research were to seek feedback from paramedics about trial participation and determine their views and preferences regarding a large-scale research study in future. Methods: Paramedics participating in REVIVE-Airways, a trial of airway management in out-of-hospital cardiac arrest, were sent a feedback questionnaire according to their study allocation. Findings: Of the total respondents, 99% were willing to participate in a further large-scale trial. Participants offered recommendations for future pre-hospital trials. Conclusion: There was strong support for further clinical trials of alternative airway management strategies during out-of-hospital cardiac arrest. Paramedics welcome opportunities to participate in research and receive feedback about trial progress and patient outcomes.
The screenplay/film relationship bifurcated: Reading Carl Mayer’s Sylvester (1924)
Authors: Ksenofontova Alexandra 
Published: May 2018

Abstract
The article explores the question of whether screenplays can be defined and interpreted based solely on their functional relation to film. It argues that another aspect of the screenplay/film relationship is crucial for a more precise definition and reading of scripts, namely the textual simulation of film as a medium. This argument is first made on a theoretical basis and supported by an analogy with the relationship between drama and theatre. The second half of the article illustrates and expands the theoretical claims in a close reading of the silent film script Sylvester written by German screenwriter Carl Mayer and published in 1924. In particular, it is argued, Mayer’s acclaimed ‘expressionist’ writing style does not aim at performing any function in the potential film production, but rather reflects a certain view on the media-related specifics of film and the possibilities of their verbal representation.
‘Real people’s lives rarely fall into a three-act structure’: Writing biographical drama for British television
Authors: Andrews Hannah 
Published: May 2018

Abstract
This article combines primary material based on interviews with British screenwriters who have written prominent dramas based on real lives with biography theory and screenwriting praxis. It seeks to analyse some of the solutions screenwriters have found to the unique challenges of writing drama based on real lives, specifically by comparing it with the developing field of biography theory. These issues are analysed in the light of the recommendations of well-known screenwriting theorist/practitioners on the creation of character and its relationship with story. The article considers some of the specific challenges for British screenwriters in creating biographical drama, given the context of public service broadcasting and its associated pressure for accuracy and fairness.
Therapeutic Plasma Exchange for Urgent Rivaroxaban Reversal
Authors: Kumar Varun , Allencherril Joseph , Bracey Arthur , Chen Alice J. , Lam Wilson W. 
Published: May 2018

Direct oral anticoagulants, which include the factor Xa inhibitor rivaroxaban, have some advantages over vitamin K antagonists in regard to stroke prevention in patients with atrial fibrillation. However, no antidotes to reverse the effect of oral anticoagulants are commercially available, which can complicate treating patients in whom reversal is urgent. We faced this challenge in a kidney transplant candidate, a 65-year-old man with end-stage renal disease who had been taking rivaroxaban for paroxysmal atrial fibrillation. When a deceased-donor kidney became available, we needed to rapidly reduce the patient's bleeding risk, while minimizing the cold ischemic time of the donor kidney. Therefore, we decided to take an experimental approach and perform therapeutic plasma exchange. The patient's plasma anti-factor Xa level decreased from 0.4 IU/mL immediately before treatment to 0.21 IU/mL afterward, indicating that rivaroxaban had been actively removed from circulation. Waste fluid showed significant anti-Xa activity, indicating that the risk of rebound anticoagulation had been mitigated. The patient subsequently underwent successful kidney transplantation.
To our knowledge, this is the first report of therapeutic plasma exchange to reverse the effects of rivaroxaban in a patient undergoing urgent surgery. This treatment may also be suitable for patients who have life-threatening, large-volume bleeding, especially in the presence of substantial kidney or liver dysfunction.
Moment functions on hypergroup joins
Authors: Vati Kedumetse , Székelyhidi László 
Published: May 2018

AbstractMoment functions play a basic role in probability theory. A natural generalization can be defined on hypergroups which leads to the concept of generalized moment function sequences. In a former paper we studied some function classes on hypergroup joins which play a basic role in spectral synthesis. Moment functions are also important basic blocks of spectral synthesis. All these functions can be characterized by well-known functional equations. In this paper we describe generalized moment function sequences on hypergroup joins.
Model-based development of a multi-agent system for controlling material flow systems
Authors: Fischer Juliane , Marcos Marga , Vogel-Heuser Birgit 
Published: May 2018

Abstract
The rising number of product variants requires flexible manufacturing systems, including their internal material flow systems (MFSs). An approach to design MFSs reconfigurably is the use of a decentralized control based on software agents. For implementing an agent-based control approach for MFSs this paper presents a meta model describing the knowledge base of individual agents and the overall control task to be fulfilled by the MFS.

摘要
完成体和经历体 “过” 是汉语语法里用来表示事件内部时间结构的重要工具，两者在语法结构和功能上有许多差异。然而当前的主流教材在初级和中级课本的编写上，多半只着重教授经历体 “过” 的用法，忽视完成体 “过” 的介绍，造成课堂语法教学无法反映语言现实的情况。本文针对两种 “过” 的教学进行了一系列研究，首先讨论两种 “过” 的区别，再综述教学语法的基本原则以及体貌标记的习得研究，然后具体分析三套在美国广受欢迎的汉语教材在教学次序、语法解释及练习活动上对两种 “过” 的处理，最后以样例示范形式提出针对 “过” 的对教材编写及教学活动的建议。
On a class of shift-invariant subspaces of the Drury-Arveson
space
Authors: Arcozzi Nicola , Levi Matteo 
Published: May 2018

Abstract
In the Drury-Arveson space, we consider the subspace of functions whose
Taylor coefficients are supported in a set Y⊂ ℕd with
the property that ℕ\X + ej ⊂ ℕ\X for all j = 1, . . . ,
d. This is an easy example of shift-invariant subspace, which can be
considered as a RKHS in is own right, with a kernel that can be explicitly
calculated for specific choices of X. Every such a space can be seen as an
intersection of kernels of Hankel operators with explicit symbols. Finally,
this is the right space on which Drury’s inequality can be optimally adapted
to a sub-family of the commuting and contractive operators originally
considered by Drury.
Curvature estimates for stable free boundary minimal hypersurfaces
Authors: Guang Qiang , Li Martin Man-chun , Zhou Xin 
Published: May 2018

Abstract
In this paper, we prove uniform curvature estimates for immersed stable free boundary minimal hypersurfaces satisfying a uniform area bound, which generalize the celebrated Schoen–Simon–Yau interior curvature estimates up to the free boundary. Our curvature estimates imply a smooth compactness theorem which is an essential ingredient in the min-max theory of free boundary minimal hypersurfaces developed by the last two authors. We also prove a monotonicity formula for free boundary minimal submanifolds in Riemannian manifolds for any dimension and codimension. For 3-manifolds with boundary, we prove a stronger curvature estimate for properly embedded stable free boundary minimal surfaces without a-priori area bound. This generalizes Schoen’s interior curvature estimates to the free boundary setting. Our proof uses the theory of minimal laminations developed by Colding and Minicozzi.
Theoretical and experimental considerations on the neutral axis of wood beams with a hole in different locations
Authors: Wen Yuxin , Yang Ping , Zhao Jian , Zhao Dong 
Published: May 2018

Abstract
Holes contribute to the non-homogeneous nature of solid wood and shift the neutral axis of wood beams away from the centroid. Based on the plane-section assumption and idealized trapezoidal distribution, new calculating formulas will be presented in terms of the location of neutral axis for clear beams and wood beams with a hole at the center, compression zone and tension zone. To verify the results of theoretical analysis and formulas, four-point bending experiments of wood beams were performed by a digital image correlation (DIC) technique. There is a reasonable agreement between calculated and experimental results with a hole at the center or in the compression zone of the beams. Concerning a hole in the tension zone, on the other hand, the calculated locations of neutral axis are not in agreement with the experimental results, due to the plastic behavior on both the compression and tension zones of the beams in the inelastic stage.
Effect of autohydrolysis on alkaline delignification of mixed hardwood chips and on lignin structure
Authors: Curmi Hélène , Chirat Christine , Brochier Salon Marie-Christine , Lachenal Dominique 
Published: May 2018

AbstractAutohydrolysis (AH) prior to the kraft process is one way to valorize hemicelluloses. The presented results show that AH also has a beneficial effect insofar as kraft cooking can be substituted by soda cooking, and higher brightness levels can be achieved under the same bleaching conditions. The lignin has more free phenolic groups after AH, which is attributable to depolymerization, and which could partly explain the better pulping and bleaching results. Another explanation could be the lower amount of lignin involved in lignin carbohydrate complexes after an AH step.

Predicative reduplication: Functions, their relationships and iconicities
Authors: Lǐ Yuèyuán , Ponsford Dan 
Published: May 2018

AbstractWe survey the predicative functions of reduplication and analyze the relationships between them in terms of semantic affinity and iconicity. Forty-five functions are identified in 108 languages. The most frequent ones have to do with repetition/continuity of events, multiplicity of participants, and intensity. Reduplication can be polysemous. Based on high cross-linguistic frequency of expression by a common reduplicative form and cases of ambiguity, we identify semantic affinities among twelve functions, together comprising a semantic map. We also analyze the functions in terms of five iconicities—iconic relationships between specific aspects of form and meaning. An interesting relationship emerges: for any pair of semantically closely related functions, the iconicities of one are always a superset of the iconicities of the other. On the widely-held assumption that initial uses are high in iconicity, the picture is one of monotonic loss of iconicity as use is extended. As well as showing empirically how the functions relate to each other, we also review three earlier proposals which were largely based on reasoning.

This issue of the journal developed from interest generated around a conference held in Cambridge entitled Art and the Brain, which examined how human neurophysiological capacities are exemplified by early art. This is a theme of great interest today, with attention focused on the ability to produce art as one of the defining characteristics of fully modern human beings, since their emergence in Africa 100,000 years ago, and the desire to understand the role of art in the story of human evolution.
Prediction of Film Cooling Effectiveness on a Gas Turbine Blade Leading Edge Using ANN and CFD
Authors: Dávalos J. O. , García J. C. , Urquiza G. , Huicochea A. , De Santiago O. 
Published: May 2018

Abstract
In this work, the area-averaged film cooling effectiveness (AAFCE) on a gas turbine blade leading edge was predicted by employing an artificial neural network (ANN) using as input variables: hole diameter, injection angle, blowing ratio, hole and columns pitch. The database used to train the network was built using computational fluid dynamics (CFD) based on a two level full factorial design of experiments. The CFD numerical model was validated with an experimental rig, where a first stage blade of a gas turbine was represented by a cylindrical specimen. The ANN architecture was composed of three layers with four neurons in hidden layer and Levenberg-Marquardt was selected as ANN optimization algorithm. The AAFCE was successfully predicted by the ANN with a regression coefficient R2<0.99 and a root mean square error RMSE=0.0038. The ANN weight coefficients were used to estimate the relative importance of the input parameters. Blowing ratio was the most influential parameter with relative importance of 40.36 % followed by hole diameter. Additionally, by using the ANN model, the relationship between input parameters was analyzed.

Published: May 2018

Einleitung:
Gesundheit ist einer der gesellschaftlichen Bereiche mit traditionell hohen Zustimmungswerten für Solidarität und Gleichheit. Vor dem Hintergrund einer Zunahme (gefühlter) gesellschaftlicher Ungleichheit in vielen Bereichen kann sich mögliche ungleiche Behandlung im Gesundheitswesen daher rasch hoher Aufmerksamkeit gewiss sein. Vor diesem Hintergrund betrachtet dieser Beitrag nach kurzen Überlegungen zu den Diskussionssträngen zum dualen Krankenversicherungssystem die Unterschiede zwischen gesetzlicher und privater Krankenversicherung in den zentralen Versorgungsbereichen – ambulante ärztliche Versorgung, Krankenhausversorgung und Arzneimittel – und geht auf die in der aktuellen politischen Debatte unterbreiteten Lösungsvorschläge ein.
Crystal structures and Hirshfeld surface analyses of seven 7-aryl-4,7-dioxoheptanoic acids: differing carboxylic acid interactions leading to dimers, chains and three-dimensional arrays

Published: May 2018

Abstract
Crystal structures and Hirshfeld surface analysis are reported of seven aryl-CO–CH2CH2COCH2CH2CO2H derivatives, namely aryl=4-ClC6H4, 1: 2-HOC6H4, 2: (2,4-(MeO)2C6H3, 3: 3,5-Me2-4-MeOC6H2, 4: 4-MeC6H4, 5: C6H5, 6: 2,4-(HO)2C6H3, 7. There are significant differences in their molecular conformations and their crystal packing. Within the group of compounds, three different types of carboxylic acid intermolecular interactions are exhibited, all involving O–H···O hydrogen bonds. These three types are (i) symmetric R2
2(8) dimers formed from pairs of O–H···O hydrogen bonds in compounds 1–5, (ii) infinite 1D homo-assemblies of carboxylic groups (homo-AA,A catemers), and (iii), a 3-D array, in which there are no direct carboxylic acid–carboxylic acid interactions, generated from O–H···O interactions of each carboxylic acid group with the hydroxyl and carbonyl groups of other molecules in 7. Each of the carboxylic acid groups in the catemer exhibit anti arrangements with all the carboxylic acid oxygen atoms lying in a plane. Disorder is exhibited in the carboxylic acid groups in 2 and 6. With the variety of oxygen substituents present in 1–7, a large number of O–H···O and C–H···O hydrogen bonds are exhibited, resulting in all cases in three dimension assemblies. In 1–5, interlayer contacts between the carboxylic acid R2
2(8) dimers in rows, with differing sets of weaker C–H···O and/or C–H···π interactions, result in the formation of two-molecular wide columns and/or infinite sheets. While column and sheet sub structures can also be designated in compound 6, on linking the carboxylic acid groups with other substituents via C–H···O, C–H···π and C=O···π interactions, these differ from those in 1–5 due to the different arrangements of the CO2H groups.
Fabrication of Ag2S/CdS Heterostructured Nanosheets via Self-Limited Cation Exchange
Authors: Ruhmlieb Charlotte , Rieckmann Angelique , Strelow Christian , Kipp Tobias , Mews Alf 
Published: May 2018

Abstract
Highly crystalline vertically aligned Ag2S/CdS heterostructured nanosheets with lateral sizes of several micrometers and thicknesses of a few nanometers are prepared directly on silver surfaces by a two-step process. Firstly, Ag2S sheets were prepared by direct reaction of partially dissolved elementary sulfur in methanol with a solid silver surface in methanol at room temperature. The second step involves a self-limited cation exchange of Ag+ vs. Cd2+ to achieve the formation of large-area Ag2S/CdS heteronanosheets on the solid substrate. The cation exchange was proven and investigated over time via several analytical methods, e.g. X-ray diffraction, Raman spectroscopy and three-dimensional photoluminescence mapping.
Repeatability of Contour Method Residual Stress Measurements for a Range of Materials, Processes, and Geometries
Authors: Olson Mitchell D. , DeWald Adrian T. , Hill Michael R. 
Published: May 2018

Abstract
This article examines the precision of the contour method using five residual stress measurement repeatability studies. The test specimens evaluated include the following: an aluminum T-section, a stainless steel plate with a dissimilar metal slot-filled weld, a stainless steel forging, a titanium plate with an electron beam slot-filled weld, and a nickel disk forging. These specimens were selected to encompass a range of typical materials and residual stress distributions. Each repeatability study included contour method measurements on five to ten similar specimens. Following completion of the residual stress measurements, an analysis was performed to determine the repeatability standard deviation of each population. In general, the results of the various repeatability studies are similar. The repeatability standard deviation tends to be relatively small throughout the part interior, and there are localized regions of higher repeatability standard deviations along the part perimeter. The repeatability standard deviations over much of the cross section range from 5 MPa for the aluminum T-section to 25 MPa for the nickel disk forging. There is a strong correlation between the elastic modulus of the material and the repeatability standard deviation. These results demonstrate the precision of the contour method over a broad range of specimen geometries, materials, and stress states.
Experimental Study of Jet Cavitation Erosion Applicable to Oil and Water-Hydraulic Equipment
Authors: Kazama Toshiharu 
Published: May 2018

AbstractHydraulic components, such as valves, pumps, and actuators, include many narrow passages in the form of nozzles, orifices, and gaps. Cavitation can occur when jets flow from high to low pressure through such sections, making it unavoidable for jets containing cavitation bubbles to impinge on the inner walls of hydraulic components. This report summarizes a series of experiments involving erosion tests, flow visualization, and pressure measurements with hydraulic oils and municipal water. For the erosion tests, the ASTM G134, Standard Test Method for Erosion of Solid Materials by a Cavitating Liquid Jet, method of jet cavitation erosion is used to evaluate the eroded mass loss and the specimen’s surface damage. The experimental apparatus consists of a stainless steel cylindrical chamber, a high-pressure hydraulic pump, and auxiliary hydraulic components. The main test parameters are the standoff distance, cavitation number, nozzle outlet geometry, specimen surface shape, and liquid type. The specimen mass is measured, and the eroded surfaces are recorded at specific intervals. For the visualization tests, an acrylic chamber and a digital video camera are used. Video frames are extracted as pictures and are processed by superposition. For the pressure measurements, pressure-sensitive films are used to estimate the pressure distributions on the impinged surfaces. The films are bonded on the specimen surface beforehand, exposed to the cavitating jets for a short period, and then analyzed using an image analysis system. Overall, by comparing the mass loss, surface damage, visualization pictures, and pressure mapping, the effects of the experimental parameters on the erosion characteristics are examined. Moreover, design approaches that are applicable to both oil and water-hydraulic components are proposed in order to reduce erosion by cavitating jets.
