Efficient, watt-level, tunable 1.7  µm fiber Raman laser in H2-filled hollow-core fibers
Authors: Huang Wei , Li Zhixian , Cui Yulong , Zhou Zhiyue , Wang Zefeng 
Published: December 2019

We report here an efficient watt-level tunable 1.7 µm fiber gas Raman laser. Pumped by a homemade pulsed fiber amplifier around 1.5 µm wavelength, a tunable laser ranging from 1687 to 1723 nm is demonstrated in a hydrogen-filled hollow-core photonic crystal fiber (HC-PCF). A maximum average power of

(pulse energy of

) is achieved on a 20-m-long HC-PCF filled with 16 bar of hydrogen gas, corresponding to a maximum Raman power conversion efficiency of 60%. A steady-state model of the rotational stimulated Raman scattering in hydrogen-filled HC-PCF, considering the pump pulse shape, is also established. The predicted output power and pulse shapes of the pump and Stokes waves are in good agreement with the experimental results. Our system offers an elegant solution for realizing efficient, tunable, and high-power fiber lasers operating at 1.7 µm wavelength range.

How to reveal topological phases and their boundaries is an intriguing issue in various systems. Entanglement, which plays a fundamental role in quantum information, has been found profoundly related to topological phases. However, experimentally exploring this relation is precluded by the limited ability to obtain entanglement in many-body systems. In this work, we propose and experimentally demonstrate that the robustness of entanglement, quantified by the von Neumann entropy, can be used to reveal the topological phase with winding number

and topological phase with

in quantum walks. With the different robustness of entanglement against perturbations of a parameter, the phase boundaries between the distinct topological phases can be further determined. As a result, our work not only offers a new perspective for quantum walks but also exhibits the deep connection between entanglement and topological physics.
Immutability and impermanence in Qiu Zhijie's work: From Buddhism to New Confucianism to Mainland New Confucianism
Authors: Kayser Christine Vial 
Published: December 2019

Abstract'The need to go back to the past' is central to Qiu Zhijie (b. 1969)'s understanding of human agency, and in consequence is central to his artistic endeavour. By 'the past' Qiu means Chinese (immutable) history and identity, based on a sense of impermanence. Chinese philosophy has informed his work from its beginning in the 1990s, as he imagined calligraphic performances, infused his installations and photographs with explicit references to Buddhist sutras and Koan. Since 2000 he has peppered his discourse and curating practices with implicit references to Confucianism (such as the celebration of the master/student relationship, the search for social harmony). Initial works used a mix of western contemporary and Chinese traditional art forms, and were concerned to the cultivation of the self. The latter have become associated with social aims such as diffusing art to the masses, promoting ancient arts and crafts in curated projects that link the artist's individual development with that of the collective. Qiu designates this holistic aim as 'Total art'. Critics explain Qiu's concept of Total art using the Wagnerian concept ofGesamtkunstwerkor of post-structural criticality of history. Others compare Qiu's endeavour to Republican New Confucianism. Still others consider it as part of Chinese literati tradition, in an ahistorical perspective. We want to emphasize rather its relation to Mainland New Confucianist philosophy that emerged since the millennium, which is characterized by a will to use ontological Chinese values to defend a political vision of Confucianism that is both social and authoritarian, essentially Chinese and opened to the world. This explains how Qiu reconciles his view of 'going to the past', with his participation in the Government's sponsored international programmes. We shall question its consequence on Qiu's position as global 'avant-garde'.
Association Between Metformin Use and Risk of Esophageal Squamous Cell Carcinoma in a Population-Based Cohort Study
Authors: Wang Qiao-Li , Santoni Giola , Ness-Jensen Eivind , Lagergren Jesper , Xie Shao-Hua 
Published: December 2019

OBJECTIVES:
Esophageal cancer is a highly fatal malignant neoplasm, with 2 etiologically different histological types. A large prospective study is expected to elucidate the specific risk of the 90% subtype of esophageal cancer, esophageal squamous cell carcinoma (ESCC), with metformin therapy. This study aims to determine the association between metformin use and incident ESCC risk.

METHODS:
This was a nationwide population-based prospective cohort study conducted in Sweden in 2005–2015. Among 8.4 million participants identified in the cohort, 411,603 (5%) were metformin users. The users were compared with 10 times as many frequency-matched nonusers of metformin (n = 4,116,030) by age and sex. Metformin use was treated as a time-varying variate, and multivariable cause-specific proportional hazards model was used to calculate hazard ratios (HR) with 95% confidence intervals (CI) for ESCC, adjusted for age, sex, calendar year, residence area, tobacco smoking, alcohol overconsumption, and use of nonsteroidal anti-inflammatory drugs or statins.

RESULTS:
The incidence rates of ESCC were 3.5 per 100,000 person-years among the metformin users and 5.3 per 100,000 person-years in the nonusers. Metformin users overall were at a decreased risk of ESCC compared with nonusers (HR 0.68, 95% CI 0.54–0.85). The decrease in risk was more pronounced in new metformin users (HR 0.44, 95% CI 0.28–0.64) and participants aged 60–69 years (HR 0.45, 95% CI 0.31–0.66).

DISCUSSION:
Metformin use decreases the risk of developing ESCC.
Fulminant Liver Failure due to Hepatitis B Reactivation During Treatment With Tocilizumab
Authors: Sonneveld Milan J. , Murad S. Darwish , van der Eijk A.A. , de Man R.A. 
Published: December 2019

ABSTRACT
Tocilizumab is a humanized monoclonal antibody targeting the interleukin-6 receptor that is frequently used for the treatment of refractory rheumatoid arthritis. Since patients with hepatitis B virus (HBV) infection were excluded from pivotal trials, the risk of HBV reactivation with this novel drug class remains uncertain. We present the first case of tocilizumab-associated HBV reactivation resulting in fulminant hepatic failure and a need for liver transplant. Our findings underscore the need for prophylactic antiviral therapy in patients being treated with novel immunosuppressive agents.

Authors: Bretas Wagner Viana , Morais Alline Sardinha Cordeiro , Hora Henrique Rego Monteiro da , Azevedo Filho Edson Terra 
Published: December 2019

Goal: This article aims to propose a model for stratifying technological information from meta-data contained in international patent bases, capable of supporting the strategic decision making that potentiates actions directed to foreign trade.
Design / Methodology / Approach: This applied research was based on the KDD - Knowledge Discovery in Databases methodology and carried out a study focused on green patents. Patent bibliographic data published in the Patent Cooperation Treaty (PCT) from 2003 to 2012, focusing on alternative energies, more precisely on biofuels, were obtained from the Derwent database, with the search string based on the Green Patents IPC Inventory, published by the World Intellectual Property Organization (WIPO). After treatment and sanitization, more than 36,000 resulting records were performed under C4.5 algorithm, denominated J-48 from the software Weka, resulting in Brazil as the destination country.
Results: A decision tree was established, in which Mexico was highlighted as the main discretionary country. It was also verified the adhesion of the other emerging countries, which, along with Brazil, compose the BRICS.
Limitations of the investigation: The proposed model is limited to areas that show intensive use of technology in products and processes.
Practical implications: It could be inferred that the proposed method can help companies to identify international markets more sensitive to a certain technology, from a free database, reliable and capable of being used by micro and small companies.
Originality / Value: In scientific communication, it is not easy to find Data mining applied to Patent database, and in this study, BRICS cluster were identified in Green patents WIPO deposit.
Digital music, online outlets and their business models
Authors: Nakano Davi 
Published: December 2019

Goal: to describe the current configuration of digital music distribution, and to give an overview of the business practices adopted by digital music outlets.
Design/Methodology/Approach: Longitudinal study using descriptive statistics and cluster analysis on two datasets collected in 2011 and 2018.
Results: Three clusters were identified in 2011: paid download, music streaming, and video streaming. Data shows that, in 2018, although streaming was the predominant technical mode, many outlets still applied the paid download business model (BM), and that cluster presented the highest survival rate. Large outlets used streaming, but the specialized ones still adhered to download, and catalog specialization and consumer behavior are the explaining factors.
Limitations of the investigation: Data was gathered from 70 digital outlets operating in two major digital markets, USA and UK, but some large ones, such as Korea and Japan, were not analyzed.
Practical implications: While a dominant technology prevails on mass markets, old technologies can still be adopted in niche markets, due to market limitations and consumer behavior. Thus, even in concentrated markets, small competitors can benefit from exploring segments with special needs that are not addressed by large players.
Originality/Value: There are few quantitative studies and longitudinal analyses on digital music business models.

Published: December 2019

This study proofing on the existence of Bugis community who lived in Karimunjawa for a long time. As ethnic migrants, Bugis ethnic community have a strong spiritual value, which is accumulated in their wandering philosophy. The philosophy ofpalettui alemu riolo tejjokamu is believed to bethe driver of their high work ethic and adaptation to the environment. In Karimunjawa, Bugis lives in several places such as in Parang village and the biggest settlement of Bugis ethnic community in Kemujan village. Bugis culture and tradition also color their lives such as tradition related to birth, the rite of transition from childhood to adolescence, marriage, death, and other tradition associated with the commemoration of religious holidays. After a long time interacting with the local community and communities of various ethnicities, they experience social changes related to changes in livelihoods, structures, and forms of the settlement, ideology, education, and so on. In line with the development of the tourism sector in Karimunjawa, Bugis people began to exploit their culture and tradition for the tourism sector such as Bugis houses built on shores for tourist lodging. The problem is that will the influx of tourists affect and erode Bugis culture in Karimunjawa? This article is intended to provide a better understanding of social change and the strategy of preserving Bugis ethnic culture in Karimunjawa. Data collection was performed by observation and field study as well as in-depth interviews. Informant selection was performed randomly to obtain homogeneous and purposive samples in order to find the appropriate informant according to the topic of research and snowball sampling to find an informant who knows the research problems based on the recommendation of other parties.
The Berber in the Texts of the Algerian Constitutions. Analysis of Discursive Practices. Discursive and Jurilinguistic Approaches
Authors: Boukherrouf Ramdane 
Published: December 2019

AbstractOur contribution consists in analyzing the discursive practices of the three Algerian constitutional texts (1996, 2002, and 2016) dedicated to the constitutionalisation of the Amazigh language. It is about showing and putting in evidence, through a textual and pragmatic analysis of these texts, the status and the definition that has been scattered over the national territory. To carry out our analysis, we will mainly appeal to the field of jurilinguistics. Moreover, the Amazigh language is defined in the constitution as a set of certified varieties throughout the national territory.
LEX.CH.IT: A Corpus for Micro-Diachronic Linguistic Investigations of Swiss Normative Acts in Italian
Authors: Canavese Paolo 
Published: December 2019

Abstract
The aim of this paper is to present LEX.CH.IT, a corpus for micro-diachronic linguistic investigations of Swiss normative acts in Italian. Italian has a peculiar position as an official minority translation language within the Swiss institutional system. Until now, few studies have focused on Swiss legal Italian, but the academic interest has been growing over the last two decades. In order to further expand on research in this field, resources such as corpora are fundamental. This is why LEX.CH.IT has been compiled. This corpus was originally created in the context of a doctoral research project, which will be briefly outlined in this paper. The main goals of the project are to determine whether clarity is a feature of Swiss legislation in Italian, whether there have been relevant evolutions over the last five decades and to assess the role of translation for a clear legislation. In the future, LEX.CH.IT could also be useful for a number of other projects aiming to shed light on the features of this language variety.
Estimates by gap potentials of free homotopy decompositions of critical Sobolev maps
Authors: Schaftingen Jean Van 
Published: December 2019

AbstractA free homotopy decomposition of any continuous map from a compact Riemannian manifold 𝓜 to a compact Riemannian manifold 𝓝 into a finite number maps belonging to a finite set is constructed, in such a way that the number of maps in this free homotopy decomposition and the number of elements of the set to which they belong can be estimated a priori by the critical Sobolev energy of the map inWs,p(𝓜, 𝓝), withsp=m= dim 𝓜. In particular, when the fundamental groupπ1(𝓝) acts trivially on the homotopy groupπm(𝓝), the number of homotopy classes to which a map can belong can be estimated by its Sobolev energy. The estimates are particular cases of estimates under a boundedness assumption on gap potentials of the form$$\begin{array}{} \displaystyle \iint\limits_{\substack{(x, y) \in \mathcal{M} \times \mathcal{M} \\ d_\mathcal{N} (f (x), f (y)) \ge \varepsilon}} \frac{1}{d_\mathcal{M} (y, x)^{2 m}} \, \mathrm{d} y \, \mathrm{d}x. \end{array}$$Whenm≥ 2, the estimates scale optimally asε→ 0. Whenm= 1, the total variation of the maps appearing in the decomposition can be controlled by the gap potential. Linear estimates on the Hurewicz homomorphism and the induced cohomology homomorphism are also obtained.
The anti-corrosion behaviour of Satureja montana L. extract on iron in NaCl solution
Authors: Pilić Zora , Dragičević Ivan , Martinović Ivana 
Published: December 2019

AbstractThe effect ofSatureja montana L. extract (SM) and phenolic fraction ofSatureja montanaL. (PF) on the corrosion behaviour of iron in 0.1 mol L-1sodium chloride solution was studied by electrochemical techniques, UV/Vis spectrophotometry and atomic absorption spectrometry. The results of all techniques showed that SM and PF contributed to iron corrosion inhibition. The calculated inhibition efficiency values were about 45% for SM and 55% for PF. Results indicate that the inhibitive action occurs via a precipitation of the Fe-complex onto the iron surface which resulting in a decrease of the passive current density. The atomic absorption spectrometry (AAS) method was applied to the quantitative determination of iron in solution. The obtained results demonstrated good agreement with results obtained by electrochemical techniques.
Writer Identity Construction Revisited: Stance, Voice, Self, and Identity in Academic Written Discourse
Authors: Li Ying , Deng Liming 
Published: December 2019

AbstractRecent research on academic discourse has revealed the intersection of writing and writer identity construction. However, some terms that are being used in writer identity study are sometimes not only interchangeably used without making an explicit connection between them but also used in a way that may cause misunderstanding. The paper is intended to tease out four key terms, namely, stance, voice, self, and identity so that the respective role that each plays in academic written discourse can be differentiated on the one hand, and their interrelationship can be clarified on the other. It is hoped that such a panoramic picture can offer some pedagogical implications for academic writing teaching and research and provide some insights into the research on writer identity construction in academic written discourse as well.
Personal and Social Voices in Written Discourse Revisited1
Authors: Bagheri Fatemeh , Deng Liming 
Published: December 2019

AbstractFor years, personal and social voices have been the issue of discussion on voice construction in written discourse (e.g., Elbow, 1999; Flowerdew, 2011; Hyland, 2002, 2010a, 2012b; Mauranen, 2013; Ramanathan & Atkinson, 1999; Tardy, 2005). However, there is a lack of an integrated examination of the dimensions which determine voice construction in writing from personal and social perspectives. This article re-examines the issue of voice construction through a critical review of previous literature on identity in written discourse. It is argued that there are five major dimensions for the construction of voice in written discourse. How writers appropriate their voice according to such five dimensions as genre, transition, culture, discipline and audience will be discussed. This paper lends further support to the view that voice in written discourse is both personal and social. As it is known, good writing expresses both personal and social voices. However, based on the dominant dimension(s), voice construction should be adjusted. Sometimes personal voice is boldly expressed; sometimes social voice is; and some other times the boundary between the two is unnoticeable. The study provides an integrated framework as well as pedagogical implications for the teaching of academic writing within L1 and L2 contexts.
A Corpus-Based Comparative Study of Generality in Chinese EFL Students’ and International Scholars’ Stance in Academic Writing
Authors: Liu Yingliang , Liu Jiaying 
Published: December 2019

AbstractAuthorial stance has attracted increasing attention in the study of second language writing. Many studies have focused on certainty in students’ academic writing, but little attention has been paid to generality in students’ academic stance. Employing a corpus-based approach, this study investigates features of generality in Chinese EFL students’ stance in academic writing through comparison with the writing of international scholars. Results show that the Chinese EFL students employed significantly more generalization markers than international scholars in their academic writing, while the international scholars used more qualified generalizations. Moreover, clear differences in the focus of generalization markers and in the distribution of qualified generalizations were found, though the two groups exhibit similar tendencies in the functions of these generalization features. The findings suggest that Chinese EFL students tend to generalize their claims to a larger scope in order to make their academic writing more persuasive, leaving an impression of exaggeration and overstatement, whereas international scholars are more likely to restrict the use of generality markers in their academic writing, making more circumscribed claims. The results have practical and pedagogical implications for second language academic writing instruction.
Instant Replay
Authors: Engell Lorenz 
Published: December 2019

Abstract
In a first part, the contribution goes through different competing and/or complementary concepts of ontography as they appear in phenomenology, object-oriented ontology, science and technology studies, and semiotics. From this comparative examination, the text develops a notion of ontography in contrast to that of ontology. It highlights the ontography of temporal objects and adds a specific media-philosophical approach to it by concentrating on the operations and tools of ontographical writing, registering or drawing being in time. In a second part, ontography is analysed as a techno-aesthetic operation on television, namely as the core of the slow motion replay. Four spectacular examples of instant replay are taken from the history of television that make the writing of an extended and malleable presence through television visible. From that, the contribution develops a hypothesis about the ontographical functioning of the medium of television and of its approach to the world.
