Authors: Udjiani SRRM Titi 
Published: November 2019

The definition of symmetric element in a ring with unity and equipped with involution can be generalized to generalized symmetric elements. But the properties of symmetric element not automatically can be generalized to generalized symmetric elements. In this paper, we discuss the property of symmetric element which can or cannot be generalized to generalized symmetric elements. Because of at least there is an element of symmetric and generalized symmetric elements which have the generalized Moore Penrose inverse, so method in this paper is by establishing a relationship between symmetric element, generalized symmetric element and generalized Moore Penrose inverse of element.

Published: November 2019

If we have two arbitrary non empty sets ,then their cartesian product can be constructed. Cartesian products of two sets can be generalized into number of sets. It has been found that if the algebraic structure of groups and rings are seen as any set, then the phenomenon of cartesian products of sets can be extended to groups and rings. Direct products of groups and rings can be obtained by adding binary operations to the cartesian product. This paper answers the question of whether the direct product phenomenon of groups and rings can also be extended at the near ring and Smarandache near ring ?. The method in this paper is by following the method in groups and rings, namely by seen that near ring and Smarandache near ring as a set and then build their cartesian products. Next, the binary operations is adding to the cartesian products that have been obtained to build the direct product definitions of near ring and near ring Smarandache.

Authors: Utami Rianti Siswi , Danardono Danardono 
Published: November 2019

Multiple imputation is one of estimation method used to impute missing observations. This method imputes missing observation several times then it is more possible to get the right estimate than just one time imputation. In this research, the method will be applied to estimate missing observations in covariates of recurrent event data. Some multiple imputation methods will be considered including combination of the event indicator, the event times, the logarithm of event times, and the cumulative baseline hazard. To compare these methods, Monte Carlo simulation will be used based on relative bias and Mean Squared Error (MSE). The recurrent events will be modelled using Cox proportional hazard model. Furthermore, real data application will be presented.

Published: November 2019

Abstract
Glutathione-chitosan conjugates are adequate carriers for anticancer treatment due to their ability for inhibition of efflux pumps, improved mucoadhesivity and in-situ gelling. These conjugates were obtained via carbodiimide at different reaction times in order to get different thiolation degrees (i.e., 4.4!, 5.1! and 7.0!) and their behavior in aqueous media at a pH of 4, 5 and 6 was assessed by measurements of hydrodynamic diameter, zeta potential and rheological analyses at a pH ranging from 4 to 6. Data examination was conducted by principal component analysis (PCA) which in turn explained 73.1! of data variability. All samples showed a Newtonian flow and thiolation rendered materials with a highly pronounced temperature-dependent behavior and a gel-like structure. In turn, the phase shift angle was the most prominent rheological change especially at a pH of 5.0 and 6.0 due to the formation of disulfide bonds. The thiolation degree was the most influential factor and it was inversely related to particle charge and consistency index.
PREDICT: a checklist for preventing preanalytical diagnostic errors in clinical trials
Authors: Lippi Giuseppe , von Meyer Alexander , Cadamuro Janne , Simundic Ana-Maria 
Published: November 2019

Abstract
Although the importance of guaranteeing a high level of preanalytical quality in routine diagnostic testing has already been largely acknowledged over the past decades, minor emphasis is currently being placed on the fact that accurate performance and standardization of many preanalytical activities are also necessary prerogatives of clinical trials. Reliable evidence exists that clear indications on how to manage the different preanalytical steps are currently lacking in many clinical trials protocols, nor have detailed authoritative documents been published or endorsed on this matter to the best of our knowledge. To fill this gap, the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) Working Group for Preanalytical Phase (WG-PRE) will provide here a specific checklist for preventing preanalytical diagnostic errors in clinical trials (PREDICT), especially focused on covering the most important preanalytical aspects of blood sample management in clinical studies, and thus encompassing test selection, patient preparation, sample collection, management and storage, sample transportation, as well as specimen retrieval before testing. The WG-PRE members sincerely hope that these recommendations will provide a useful contribution for increasing the success rate in clinical trials.
Social bureaucracy? The integration of social media into government communication
Authors: Figenschou Tine Ustad 
Published: November 2019

AbstractInspired by an institutional logics approach, this article analyzes the barriers to and drivers of the integration of social media in the communication practices in Norwegian ministries. Drawing on rich ethnographic data, the paper analyzes the process of integrating social media logic into government communication units that were largely organized through a news media regime. To understand the process, it emphasizes four dimensions: how the symbolic resources, material resources, formal rules and practices have defined the logics of government communication in the period studied (May 2015–May 2016). The analysis meets the call for more empirical investigation into the interplay between the traditional news logics and new digital logics.
Two General Lessons from the 2019 Personal Income Tax Reform of China
Authors: An Zhiyong 
Published: November 2019

Abstract
We have identified two general lessons, suggested from the 2019 personal income tax reform of China, regarding third-party reporting, tax compliance, and tax incidence. First, third-party reporting is an effective mechanism to enforce tax compliance. Second, tax evasion can affect tax incidence. We argue that these two general lessons are important for both academic researchers and policymakers.

Authors: Guo Xuesong , Kapucu Naim 
Published: November 2019

Abstract
Participatory System Dynamics modeling is presented as a methodology to engage stakeholders in collaborative decision making in scenarios involving humanitarian logistics. Using the System Dynamics (SD) model, we simulated different scenarios, the results of which yielded factors that influence performance of humanitarian logistics. Once these were identified and discussed, different options on performance improvement were tested. This approach showed that the SD model can facilitate system thinking for stakeholders and form shared mental models critical to reaching consensus-based decisions in humanitarian logistics situations.
Framing constructicography
Authors: Boas Hans C. , Lyngfelt Benjamin , Torrent Tiago Timponi 
Published: November 2019

Abstract
Constructicography can be defined as a blend between Construction Grammar and Practical Lexicography, which aims at developing constructicons: repositories of form and function pairings in a language. In this paper, we present a comprehensive overview of this emerging field by (i) tracking the origins of both Frame Semantics and Construction Grammar and the repercussions of their intertwined developments to Computational Lexicography and Constructicography; (ii) comparing the impacts of the different degrees of interconnection between constructicons and framenets and (iii) discussing the possible applications of these resources. Also, we argue that Constructicography, while obviously building on the accumulated knowledge compiled by numerous Construction Grammar approaches to language, also contributes to its mother theory, since the effort to build coherent formalized computational resources forces constructionist analysis to go beyond describing families of constructions into the enterprise of describing a coherent construction grammar of a language.
The German Constructicon Project: Framework, methodology, resources
Authors: Ziem Alexander , Flick Johanna , Sandkühler Phillip 
Published: November 2019

Abstract
The paper introduces aims and efforts of the German Constructicon Project (GCP) (www.german-constructicon.de) hosted at the University of Düsseldorf. The ultimate goal of the project is not only to identify and describe oftentimes overlooked grammatical constructions, but also to offer comprehensive descriptions of them in a dictionary-like online repository. Each construction entry is intended to provide all relevant grammatical information necessary to understand and correctly use the respective grammatical construction. Based on constructicographical analyses of authentic corpus examples, the paper reports on the methodological foundations of GCP, most importantly the annotation categories used, as well as on the computational work routine yielding construction entries. The routine includes five consecutive steps, (i) subcorporation and preliminary analysis, (ii) parsing pipeline (automatic annotations of part of speech, phrase type and grammatical function), (iii) semantic annotations, (iv) semi-automatic analyses of the annotations and, finally, (v) compilation of construction entries. For illustration, we present the geschweige denn (‘let alone’) construction in its habitat of the negating_connector construction family. The paper concludes with outlining a full-fledged construction entry for geschweige denn in the German Constructicon.

First, the theoretical framework will be defined (chapter 2) and then the concepts ‘internalʼ and ‘external syntaxʼ will be discussed (chapter 3). In chapter 4, the methods and problems of practical implementation are illustrated by means of specific case studies.
Towards a valency and argument structure constructicon of English: Turning the valency patternbank into a constructicon
Authors: Herbst Thomas , Uhrig Peter 
Published: November 2019

Abstract
This article describes the project of a Valency Constructicon, i. e. a constructicon that covers low level valency constructions of individual verbs and links them to more general argument structure constructions. It will be shown how the Erlangen Valency Patternbank can be converted into a constructicon. The project is intended to develop a new type of reference work, but at the same time it can be seen as a test case for constructionist theory with respect to the generalizability of constructions.
Interpreting collocations: An analysis of collocation dictionaries of: English, German and Russian
Authors: Garibyan Armine 
Published: November 2019

Abstract
Unless online collocation tools have not become common yet, printed collocation dictionaries are still one of the few sources of checking collocative possibilities of a lexical unit. The aim of this paper is to analyse one printed collocation dictionary in each of the 3 languages: English, German and Russian and see which interpretation of collocation was focused on and what user groups were targeted. Also, it was attempted to see whether the morphological specificity of the languages was taken consideration of as compared to the structure of these dictionaries, and further determine whether inclusion or exclusion of certain language-specific information aims at a particular group of target users.
Imprinted plasmonic measuring nanocylinders for nanoscale volumes of materials
Authors: Zhu Jinfeng , Chen Xizhao , Xie Yinong , Ou Jun-Yu , Chen Huanyang , Liu Qing Huo 
Published: November 2019

Abstract
Optical measurement of materials at the nanoscale is important for nanotechnology. Various plasmonic nanorulers have been studied for measuring nanoscale distance and orientation of materials, but they lack the capability to contain and measure nanoscale volumes, especially for liquid or soft materials. Here, we demonstrate the use of imprinted plasmonic volumetric nanocylinders, which act as nanoscale graduated cylinders and facilitate nanomaterial measurement via visible light. Our theoretical and experimental achievements illuminate a promising method for non-destructive, low-cost and fast measurement of material volume changes at the nanoscale, which will benefit the fields of analytical chemistry, nanofabrication and biomedical sensing.
Hydrophobin HGFI–based fibre-optic biosensor for detection of antigen–antibody interaction
Authors: Duan Shaoxiang , Wang Bo , Qiao Mingqiang , Zhang Xu , Liu Bo , Zhang Hao , Song Binbin , Wu Jixuan 
Published: November 2019

Abstract
A compact S-tapered fibre biosensor functionalised with class I hydrophobin HGFI found in Grifola frondosa has been proposed for the first time to accrue label-free detection of reaction between goat–anti-rabbit immunoglobulin G (IgG) (GAR, antibody) and rabbit–anti-hemagglutinin IgG (R, antigen). The HGFI nanolayer self-assembled on fibre surface provides a distinguished analytical platform to implement biocompatible binding owing to its prominent amphiphilicity and remarkable optical as well as biochemical properties. Water contact angle measurements, atomic force microscopy, and immunofluorescence assay are utilised to characterize the modification properties of siliconised substrate surface with HGFI. Functionalisation of the S-tapered fibre is achieved by exploiting self-assembly of HGFI and immobilisation of GAR for specific R detection. HGFI with a concentration of 300 μg/ml allows the formation of a self-assembled amphipathic film on fibre surface, which can adsorb antibody smoothly with such desirable merits as ease of operation, fast response, good stability, good repeatability, and no side effects. Immunoassay experiments are conducted based on dip wavelengths interrogation of the interferometric transmission spectrum. In this study, we propose a novel antigen detection scheme, which could be extended for the detection of other biomolecules owing to its high integration, good specificity, real-time detection, and simple detection scheme.

Published: November 2019

Abstract
Graphene has been widely used in silicon-based optical modulators for its ultra-broadband light absorption and ultrafast optoelectronic response. By incorporating graphene and slow-light silicon photonic crystal waveguide (PhCW), here we propose and experimentally demonstrate a unique double-layer graphene electro-absorption modulator in telecommunication applications. The modulator exhibits a modulation depth of 0.5 dB/μm with a bandwidth of 13.6 GHz, while graphene coverage length is only 1.2 μm in simulations. We also fabricated the graphene modulator on silicon platform, and the device achieved a modulation bandwidth at 12 GHz. The proposed graphene-PhCW modulator may have potentials in the applications of on-chip interconnections.

Published: November 2019

Abstract
Copper matrix composites reinforced with 1, 3, 5, 7 vol.% Cu-coated SiC whiskers of consistent orientation (SiCw/Cu) were prepared by powder metallurgy and hot extrusion. The microstructure of composites was investigated by scanning electron microscopy. The SiC whiskers were arranged along the direction of hot extrusion and distributed uniformly. The composites were fabricated into specimens with different whisker orientations, and their electrical conductivity was tested. The effects of SiC whiskers orientation and content on the electrical conductivity of composites were investigated through experiment. Results show that the SiC whiskers content was the major factor affecting the electrical conductivity of the composites. With increasing SiC whisker orientations angel, the electrical conductivity of composites is improved. The electrical conductivity model has been established by taking into account the SiC whiskers content, whisker orientation and microstructure parameters, and the results were in good agreement with experimental data.

Graphical abstract: Copper matrix composites reinforced with SiC whiskers of consistent orientation were prepared. The orientation of SiC whiskers changes from 0∘ to 90∘, resulting in electrical conductivity anisotropy of composites.
The United States and European Defense Cooperation European Strategic Autonomy and Fighter Aircraft Procurement Decisions
Authors: Hellemeier Lucas Fernando 
Published: November 2019

Abstract
This paper addresses a topic that has taken on increasing urgency since the presidency of Donald Trump: how can the European Union member states insure strategic autonomy in military defense? One answer given by policymakers and academics alike is that an independent industrial-military base is central to achieving autonomy. In particular, the production and procurement of military equipment ought to be EU-internal. However, the US remains the most important provider of military equipment worldwide, and many EU member states continue to procure from the US. In this context, this paper asks why some EU member states procure fighter jets from the US while others procure from European sources. It hypothesizes that those countries with a security or economic dependence on the US are more likely to continue to procure from the US. The paper tests this hypothesis with a statistical analysis that seeks a relationship between indicators of security and economic dependence on the US and procurement decision. The results this analysis yields are mixed, but I find that on average European countries that decide to procure US-made fighter are more subordinate to the US.
Fiscal policy uncertainty and US output
Authors: Popiel Michal Ksawery 
Published: November 2019

Abstract
The rise in US partisan conflict following the Great Recession led to a popular belief that uncertainty about fiscal policy was impeding output growth. I explore this hypothesis by nesting it in a standard structural vector autoregression (SVAR) model traditionally used for estimating fiscal multipliers. I augment the model with stochastic volatility (a measure of uncertainty) and allow that to interact with the endogenous variables. I consider various trend assumptions, subsamples and information sets and find that the evidence does not support this hypothesis. The results reveal that there is no systematic relationship between fiscal policy uncertainty and output. Moreover, a time-varying parameter version of the model shows that the lack of consistency across specifications is not driven by changes in the transmission of uncertainty shocks over time. Finally, I revisit Fernández-Villaverde, Guerrón-Quintana, Kuester, and Rubio-Ramírez (Fernández-Villaverde, J., P. Guerrón-Quintana, K. Kuester, and J. Rubio-Ramírez. 2015. “Fiscal Volatility Shocks and Economic Activity.” American Economic Review 105: 3352–3384) who find a significant negative relationship between fiscal policy uncertainty and output. I show that when their estimation is modified to incorporate the uncertainty around the estimate of uncertainty, their empirical result falls in line with the findings in this paper.

Abstract

Background
Neutrophil-mediated killing of pathogens is one of the most significant functions of the primary defense of the host. Neutrophil activity and migration play a key role in inflammatory conditions. To gain insights into the interactions between neutrophils and neutrophil migration-related disorders, a large number of sophisticated methods have been developed. The technical limitations of isolating highly purified neutrophil populations, minimizing both cell death and activation during the isolation process, and the short lifespan of neutrophils present challenges for studying specific functions of neutrophils in vitro. In this study, we aimed to evaluate a separation medium-based density gradient method to obtain highly purified neutrophil populations and combined this protocol with a model for studying neutrophil migration in-vitro.

Materials and methods
Human granulocytes were isolated using Lympholyte-poly solution. The purity and viability of isolated neutrophils were assessed by flow cytometry and morphological analysis. Neutrophil activation was confirmed by immunocytochemistry. Lastly, filter assay was performed to measure neutrophil chemotaxis.

Results and discussion
All validation experiments revealed that this method was capable of generating a highly purified neutrophil population for further functional in-vitro assays. Consequently, this study demonstrates a quick, cost effective, and easy-to-follow model, and may be a significant alternative to isolation methods that need extra subsequent steps such as flow cytometry-based cell sorting for reaching highly purified neutrophil population.

Conclusion
The suggested combination of methods for the isolation and cell migration analysis of human neutrophils is highly recommended to use for disease models involving neutrophil migration such as autoinflammatory disorders.
