Impact of Pointing Error on the BER Performance of an OFDM Optical Wireless Communication Link over Turbulent Condition
Authors: Barua Bobby , Majumder S. P.
Published: May 2020

An analytical approach is developed in this paper to evaluate the bit error rate (BER) performance of an optical wireless (OW) communication system with multiplexing of the RF orthogonal frequency division (OFDM) over turbulent condition taking into account the effect of pointing error. The received signal is detected through direct detection receiver followed by RF synchronous demodulation including the effect of OW channel and different form of noises such as receiver thermal noise, background channel noise and photo detector shot noise. Analysis is developed for an OFDM system over the OW channel, taking into account the effect of pointing error between the transmitter and the receiver in turbulent condition and the analysis reveals that the OFDM OW system is less affected by pointing error with deference to the major power penalty at BER performance. For instance, power penalty at BER 10−9 is found to be 3 dB for 256 OFDM subcarriers with 9 millidegree displacement angle at a data rate of 10 Gbps under turbulent condition. It is found that the system is more influenced by the atmospheric turbulence at a higher data rate.
Improvement in glycaemic parameters using SGLT-2 inhibitor and GLP-1 agonist in combination in an adolescent with diabetes mellitus and Prader-Willi syndrome: a case report
Authors: Candler Toby , McGregor David , Narayan Kruthika , Moudiotis Chris , Burren Christine P.
Published: May 2020

Objectives

Prader-Willi Syndrome (PWS) is characterised by hyperphagia often leading to obesity; a known risk factor for insulin resistance and type 2 (T2) diabetes. We present a prepubertal girl with PWS who developed diabetes.

Case presentation

Our case was diagnosed with PWS in infancy following investigation for profound central hypotonia and feeding difficulties. She commenced growth hormone (GH) aged 8 years for short stature and treatment improved linear growth. At age 12 years, she presented with polydipsia, polyuria and vulvovaginitis. She was overweight (BMI SDS +1.43). Diabetes was diagnosed (Blood glucose = 24.2 mmol/L, HbA1c = 121 mmol/mol or 13.2%). She was not acidotic and had negative blood ketones. Autoantibodies typical of type 1 diabetes were negative. She was initially treated with basal bolus insulin regime. GH was discontinued 3 months later due to concerns regarding GH-induced insulin resistance. Off GH, insulin requirements reduced to zero, allowing Metformin monotherapy. However off GH, she reported significant lethargy with static growth and increased weight. Combinations of Metformin with differing insulin regimes did not improve glucose levels. Liraglutide (GLP-1 agonist) and Metformin did not improve glucose levels nor her weight. Liraglutide and Empaglifozin (SGLT-2 inhibitor) therapy used in combination were well tolerated and demonstrated rapid normalisation of blood glucose and improvement in her HbA1c to within target (48 mmol/mol) which was sustained after 6 months of treatment.

Conclusions

Newer treatments for type 2 diabetes (e. g. GLP-1 agonists or SGLT-2 inhibitors) offer potential treatment options for those with diabetes and PWS when conventional treatments are ineffective.
Rates of metabolic acidosis at birth and Apgar score values at 1, 5, and 10 min in term infants: a Swedish cohort study
Authors: Cnattingius Sven , Johansson Stefan , Razaz Neda
Published: May 2020

Background

Metabolic acidosis, measured in arterial umbilical cord blood at birth, is the most accepted definition of birth asphyxia. The aim of the study was to investigate the rates of metabolic acidosis across the entire range of Apgar score values (0–10) at 1, 5, and 10 min in term infants.

Methods

In a population-based Swedish cohort of births between 2008 and 2013, we included 85,076 term (≥37 weeks) non-malformed infants with information from umbilical arterial blood gas analyses and complete information on Apgar scores (0–10) at 1, 5, and 10 min.

Results

Rates of metabolic acidosis generally decreased with increasing Apgar score values. For Apgar score at 1 min, this decrease was consistent from Apgar score 0 (35%) to Apgar score 10 (0%). For Apgar scores at 5 and 10 min, the decrease was consistent for Apgar score values from 6 to 10.

Conclusion

Although there is a close association between Apgar score values and rates of metabolic acidosis, Apgar score is not and should not be used as a measure of birth asphyxia.

Published: May 2020

Background

The aim of the current study is the longitudinal epidemiological study of pregnancies, their outcome and the changes in their treatment, in patients with hemoglobinopathies, during 30 years at a Thalassemia and Sickle Cell Department.

Methods

The data of a total of 47 pregnancies of 40 women with hemoglobinopathies monitored in the Thalassemia and Sickle Cell Department of Hippokrateio General Hospital of Athens were retrospectively collected. The data were divided and evaluated in two time periods, the first before 2000 and the second between 2000 and 2017.

Results

There were four miscarriages and 43 completed pregnancies. The mean pregnancy duration was 34.92 weeks. Thalassemia major and thalassemia intermedia patients had higher percentages of in vitro fertilization (IVF) pregnancies and IVF attempts, with the majority of IVF attempts and pregnancies in the time period after 2000. During the period 2000–2017, more women received transfusions and iron chelation therapy both before and during pregnancy compared to the period before 2000. During the period 2000–2017, three women presented hemorrhagic complications. Placental abruption occurred in two cases, while one woman suffered a stroke. Six women had liver disease and two cardiac problems.

Conclusion

The rate of pregnancies in women with hemoglobinopathies has increased after the year 2000 due to the increased use of IVF technique. Pregnancy planning, close collaboration between gynecologists and hematologists and appropriate pregnancy monitoring are essential for an optimal pregnancy outcome.
Husserl's Project, Critique, and Idea of Reason
Authors: Cimino Andrea
Published: May 2020

The present study seeks to accomplish three goals: to shed light on the problem of reason in Husserl’s co-inherited philosophicalproject, to elucidate his transcendentalcritiqueof reason, and to present Husserl'sideaof reason in its distinctive features. A historical excursus first provides a frame to understand the necessity of a critique of reason, its proper subject-matter, and its function for the project of genuine philosophy. In particular, this historical reflection identifies the form that a critique must assume in order to fulfil its philosophical-scientific task. The focus is then directed at Husserl's methodological recalibration of the problem of reason. Husserl's ‘prinzipielle Kritik’ is elucidated in his transcendental reassessment of the headings ‘reason’ and ‘unreason,’ and is thought in connection to the concept ofSelbstbesinnung. Lastly, Husserl’s idea of reason is reconstructed in relation to, and in disambiguation from, the concepts of self-evidence, logos, synthesis, fulfilment, positing, etc. Reason, as teleological rule and structural form of transcendental subjectivity, is clarified in its dependence on, and irreducibility to, the problems of constitution and in light of the question of its objective/subjective character.
La traducción del lenguaje figurado: figuras de dicción y de pensamiento en la obra de François Villon
Authors: Ojeda Beatriz Martínez
Published: May 2020

The current article primarily aims at analysing the strategies utilised by quintessential translators of F. Villon to render into Spanish the figures of diction and thought that characterise the poetry of the 14th-century author, following the classical classification proposed by Abrams (1953). A second objective is to suggest a set of guidelines on how to translate the figurative use of discourse into a given target-language text. Accordingly, this article will first provide an overview on the most relevant approaches to poetry translation, which especially concern relaying the figurative language of a source into a target-language text. Moreover, it will analyse a set of examples that best illustrate the distinctive use of rhetorical devices by Villon, and will examine the ways to better transforming them into another target language, namely Spanish. Lately, this article will propose a set of translation guidelines for both the figures of diction and thought that permeate his poetry.
Partitive determiners in Piedmontese: A case of language variation and change in a contact setting
Authors: Cerruti Massimo , Regis Riccardo
Published: May 2020

This paper addresses the use of partitive determiners in Piedmontese as a case in point for the interplay of language variation and change in Italo-Romance. Firstly, a brief diachronic account will be provided of the development of partitive determiners in Piedmontese, ranging from the twelfth and thirteenth centuries to the nineteenth and twentieth centuries; such an overview will rely upon the results of recent studies on this subject. Next, the behavior of partitive determiners in contemporary Piedmontese will be examined; we will draw primarily on some unpublished materials collected within the ALEPO research program (ALEPO stands forAtlante linguistico ed etnografico del Piemonte Occidentale, “Linguistic and Ethnographic Atlas of Western Piedmont”), which consist of both responses to a questionnaire survey and spontaneous speech data. The study will help to shed light on the similarities and differences not only between different varieties of Piedmontese, but also between such varieties and Italian. The main paradigmatic differences identified will be argued to relate to two different ways of categorizing the relationship between mass nouns and countable plurals, one in which quantification prevails over classification, and the other in which classification is foregrounded. This state of affairs will then be discussed against the backdrop of the sociolinguistic situation under scrutiny, paying special attention to the contact between Piedmontese and Italian (as well as with French up to the end of the nineteenth century) and to the “superposition” of both an official standard language (i. e., Italian) and a regional koine (based on the variety of Turin) over local varieties of Piedmontese.
To Re-present a Nobel Prize Winner. Interpreting a Public Literary Conversation
Authors: Poignant Elisabeth Geiger , Wadensjö Cecilia
Published: May 2020

This article examines the unfolding of interaction in a growing and, so far, scarcely examined social and cultural practice – interpreter-mediated public literary conversations. In this context, the activity of interpreters, although indispensable when authors and audiences do not share a common language, is sometimes regarded as a “necessary evil” that allegedly causes delays and information loss. Exploring an interpreter-mediated public literary conversation with Nobel Laureate Svetlana Alexievich as a case in point, the focus of this article is rather on what the presence of an interpreter might add to the shared performance on stage. Attention is drawn to the temporal evolvement of the interlocutor’s communicative resources, evident within narrative sequences, drawing on prosody research and research on gestures. The study suggests that, apart from keeping the non-Russian speaking audience updated on content, the interpreter’s rhythmically calibrated performance adds an energizing asset to the event as a whole. The notion of the “coupled turn”, internally hosting gestural and prosodic coherence across topical boundaries and language frame shifts, emerges as a usable unit for the analysis.
Critical Transmodal Pedagogies: Student Teachers Play with Genre Conventions
Authors: Govender Navan N.
Published: May 2020

This paper explores how student teachers navigated moving between different modes of representation from written text to image. This enabled some students to play with genre conventions, rethink the relationship between word and image, and explore multimodality in interesting ways. Working at the intersection of Kress’ work on Multimodality, Newfield’s transmodal moment and the critical literacy project, I designed and implemented a course for English secondary education in one school of education in South Africa. Firstly, this article outlines the course’s aims and assessment to consider how multimodality might feature in a unit of work for student teachers. Specific focus is given to the final assessment task that required students to make a ‘transmodal shift’ from linguistic to visual-linguistic; from written narrative to multimodal storytelling. Secondly, a critical multimodal discourse analysis of students’ visual narratives is applied to explore how critical transmodality enabled some student teachers to imagine beyond traditional narrative structures and explore multimodal semiotic resources in innovative ways, relevant to the secondary English classroom. Finally, I conclude by considering the implications of multimodal semiotic play for both research and classroom practice in language and literacy education, including assessment, the value of non-linguistic modes, and genre as a construct of power.
Aroi Mai? The Multimodality of Thainess in Thai Tourism Videos
Authors: Jocuns Andrew
Published: May 2020

This paper offers two contributions to the multimodal discourse analysis of tourism advertising videos. First it shows how Thainess has been resemiotized to be accessible to non-Thai people and second it illustrates how the mediated action can be used as a unit of analysis to analyze advertising videos. Thainess has been a national identity strategy that has evolved into numerous polysemic. In this discussion five discursive stances to Thainess are identified: Thainess as a national identity, Thainess as a form other-ness, the Thai-ification of Thai people, Thainess as popular culture, and Thainess as commodified consumption. The analysis uses an integrative framework based in mediated discourse theory, multimodal discourse analysis and social semiotics to discuss and analyze the discursive stances of Thainess that emerge in two videos from the 2015 Discover Thainess campaign. Using the mediated action as the unit of analysis the multimodal features of Thainess that emerge from these videos are analyzed. Through this analysis Thainess is shown to be resemiotized in the videos where it was once inaccessible to westerners, the Thainess represented in the videos has been resemiotized to be both accessible and authentic to western tourists.

A case of a severe anaphylactic reaction during general anesthesia was reported. Despite the high suspicion for cefuroxime as a trigger of the anaphylactic reaction, cisatracurium emerged being the culprit drug. This case illustrates the importance of testing all drugs used during procedures/operations, trying to find a culprit of anaphylaxis.
»Ich bin stark und mir passiert nichts« – Forschungspraktische und methodische Erkenntnisse aus einer quantitativen Opferbefragung im Gefängnis
Authors: Hofinger Veronika , Fritsche Andrea
Published: May 2020

Um die Bedingungen, das Ausmaß und die Betroffenheit von Gewalt in totalen Institutionen wie dem Gefängnis zu verstehen, bedarf es solider empirischer Grundlagen. Mit Hilfe von Dunkelfeldbefragungen können auch Gewaltvorfälle analysiert werden, die der Institution bzw. der Öffentlichkeit nicht bekannt sind. Doch Opferbefragungen sind mit einer Reihe theoretischer und methodischer Herausforderungen verbunden, die sich im Kontext der Haft weiter zuspitzen: Die institutionellen Charakteristika, die Diversität der Häftlingspopulation, die Normalität von Gewalt im Gefängnis und damit verbunden die notwendige Demonstration von Männlichkeit sowie die enge Verbindung zwischen Täter- und Opferschaft haben Auswirkungen auf die Stichprobenzusammensetzung, die Teilnahmebereitschaft und die Thematisierbarkeit von Gewalterfahrungen. Die Einhaltung ethischer Standards ist in einem Feld, das den Prämissen von Sicherheit und Kontrolle verpflichtet ist, zusätzlich herausfordernd. Auf Basis einer repräsentativen Befragung (n = 386) in zehn österreichischen Justizvollzugsanstalten zu Erfahrungen psychischer, körperlicher und sexueller Gewalt werden methodische Zugänge und Lösungsansätze diskutiert, die zur Ausleuchtung des Dunkelfeldes beitragen sollen. Für die Thematisierbarkeit von Gewalt in Haft sind nicht nur Erkenntnisse der Erforschung von Gewalterfahrungen von Männern zu berücksichtigen. Um das große Potenzial von Face-to-Face-Befragungen auszuschöpfen, ist eine situations- und personensensible, dynamische und zeitlich flexible Handhabung der quantitativen Messinstrumente notwendig. So generierte qualitative Evidenz schafft inhaltliches Wissen, das nicht nur die Interpretation der Zahlen unterstützt, sondern ermöglicht, das Phänomen von Gewalt im Gefängnis in seiner Bedeutung und in seinen konkreten Erscheinungsformen besser zu verstehen. Auch was nicht erzählt wird, erzählt uns etwas über die totalste aller Institutionen.
Recurrences for the genus polynomials of linear sequences of graphs

Given a finite graph H, the n

n−1 by adding edges or identifying vertices, always in the same way. The genus polynomial Γ

Published: May 2020

We denote the local “little” and “big” Lipschitz functions of a function f : ℝ → ℝ by lip f and Lip f. In this paper we continue our research concerning the following question. Given a set E ⊂ ℝ is it possible to find a continuous function f such that lip f = 1

E
or Lip f = 1

E
?

In giving some partial answers to this question uniform density type (UDT) and strong uniform density type (SUDT) sets play an important role.

In this paper we show that modulo sets of zero Lebesgue measure any measurable set coincides with a Lip 1 set.

On the other hand, we prove that there exists a measurable SUDT set E such that for any Gδ
set E͠ satisfying ∣EΔE͠∣ = 0 the set E͠ does not have UDT. Combining these two results we obtain that there exist Lip 1 sets not having UDT, that is, the converse of one of our earlier results does not hold.

Some properties of D-weak operator topology
Authors: Polakovič Marcel
Published: May 2020

Let 𝓖
D
(𝓗) denote the generalized effect algebra consisting of all positive linear operators defined on a dense linear subspace D of a Hilbert space 𝓗. The D-weak operator topology (introduced by other authors) on 𝓖
D
(𝓗) is investigated. The corresponding closure of the set of bounded elements of 𝓖
D
(𝓗) is the whole 𝓖
D
(𝓗). The closure of the set of all unbounded elements of 𝓖
D
(𝓗) is also the set 𝓖
D
(𝓗). If Q is arbitrary unbounded element of 𝓖
D
(𝓗), it determines an interval in 𝓖
D
(𝓗), consisting of all operators between 0 and Q (with the usual ordering of operators). If we take the set of all bounded elements of this interval, the closure of this set (in the D-weak operator topology) is just the original interval. Similarly, the corresponding closure of the set of all unbounded elements of the interval will again be the considered interval.

Published: May 2020

Analysing dynamics of a single biomolecule using high-resolution imaging techniques has been had significant attentions to understand complex biological system. Among the many approaches, vertical nanopillar arrays in contact with the inside of cells have been reported as a one of useful imaging applications since an observation volume can be confined down to few-tens nanometre theoretically. However, the nanopillars experimentally are not able to obtain super-resolution imaging because their evanescent waves generate a high optical loss and a low signal-to-noise ratio. Also, conventional nanopillars have a limitation to yield 3D information because they do not concern field localization in z-axis. Here, we developed novel hybrid nanopillar arrays (HNPs) that consist of SiO2 nanopillars terminated with gold nanodisks, allowing extreme light localization. The electromagnetic field profiles of HNPs are obtained through simulations and imaging resolution of cell membrane and biomolecules in living cells are tested using one-photon and 3D multiphoton fluorescence microscopy, respectively. Consequently, HNPs present approximately 25 times enhanced intensity compared to controls and obtained an axial and lateral resolution of 110 and 210 nm of the intensities of fluorophores conjugated with biomolecules transported in living cells. These structures can be a great platform to analyse complex intracellular environment.

Neuroscience in transgender people: an update
Authors: Kiyar Meltem , Collet Sarah , T’Sjoen Guy , Mueller Sven C.
Published: May 2020

Transgender persons identify with a gender different from the one they were assigned at birth. Although describing oneself as transgender is not a new phenomenon, media attention has lately been increasing exponentially, thanks to progressive changes in laws and change in societal attitudes. These changes also allow more people nowadays to (openly) identify as transgender and/or seek gender-affirming treatment. However, simultaneously, not much is presently understood about the underlying neurobiology, and specifically the brain structure and brain function of transgender persons. One major question in neuroimaging and neuroscience has been to determine whether, at the brain level, transgender people resemble more their gender identity, their sex assigned at birth, or have a unique neural profile. Although the evidence is presently inconsistent, it suggests that while the brain structure, at least before hormonal treatment, is more similar to sex assigned at birth, it may shift with hormonal treatment. By contrast, on “sex-stereotypical tasks,” brain function may already be more similar to gender identity in transgender persons, also before receiving gender-affirming hormone treatment. However, studies continue to be limited by small sample sizes and new initiatives are needed to further elucidate the neurobiology of a ‘brain gender’ (sex-dimorphic change according to one’s gender).
Disrupting Digital Divide Narratives: Exploring the U.S. Black Diasporic Immigrant Context
Authors: Ndumu Ana
Published: May 2020

The purpose of this study is to probe biased library and information science (LIS) presumptions of digital divides among U.S. immigrants. The stance of the foreign-born as “digital immigrants” departs from migration and population research which hold that gaps in immigrant Internet and technology access are rapidly closing, even when accounting for immigrant type. The research is based on analysis of the 2016 U.S. Census Bureau American Community Survey data. Black immigrant households’ ICT device and Internet access were determined and then compared to those of the general population. Findings suggest that Black immigrant households primarily access the Internet through smartphone and laptop devices along with mobile and at-home hi-speed Internet plans. When compared to the general population, Black immigrant households demonstrate significantly greater smartphone access, and they maintain comparable levels of hi-speed Internet and computer/laptop device access. This study adds to a growing body of research on the narrowing digital divide gap among U.S. immigrants. Immigrants rely on the Internet to transition and integrate into U.S. society.
“The Earth Is Flat!” The Literary Complexity of Truth, Lies and Fake Knowledge
Authors: Larsen Svend Erik
Published: May 2020

Truth is never self-evident or based on ocular proof alone. It has to be based on an argument and, thus, to be shaped for communication, which makes knowledge with a truth-claim a social phenomenon that can only be obtained through a complex mediation of theoretical preconditions, research technology, interdisciplinary collaboration and significant financial investments. Moreover, it is always disseminated in a politically charged context through complex media platforms, today ranging from journals and monographs to social media. The contemporary debate on truth-claims, and thus on ontology and epistemology, often lacks historical perspective beyond its contemporaneity nurtured by the debates about fake news. Yet, the awareness of the lies and fake knowledge this modern complexity may release was clear already in the emerging modern entanglement of science and culture during the Enlightenment, before electronic media. A reading of the comedy “Erasmus Montanus” (1731) by Ludvig Holberg serves as a case in point.

Digital Media, Fears, and Their Ontological Demagogic Power: Utopia, Homeland, Occupied
Authors: Bezrucka Yvonne
Published: May 2020

The article aims to focus on the rhetoric of TV-series. Utopia, Homeland, and Occupied, are thus examined in their characterizing traits, being all constructed via the epistemic filter of a fear-eristics that often produces an oversimplified propaganda jargon linked to a racist imagology. How these digital, but ontologically guided, rhetorical strategies then work with populism is made clear in the essay.
Aqueous two-phase systems as a tool for bioseparation – emphasis on organic acids
Authors: Yankov Dragomir
Published: May 2020

Aqueous two-phase systems (ATPS) are universally recognized as an excellent alternative to the conventional separation techniques in the biotechnology, because of their undoubted advantages such as mild and biocompatible conditions, high water content, low interfacial tension, ease of process integration and scale up, etc. The formation of ATPS is due to the incompatibility of two polymers in a common solution. Other types of ATPS are formed by polymer/salt, ionic and/or non-ionic surfactants, inorganic salt/short-chain alcohols, and based on room temperature ionic liquids. ATPS are successfully used (even in large scale) for cells, enzyme and protein separation, while their application for recovery of small molecules such as organic acids, antibiotics, alcohols is more complicated as they are usually hydrophilic and tend to distribute evenly between the phases. The purpose of this paper is to overview and summarize the efforts made for the application of different types of ATPS for the separation of organic acids.

Computational methods towards increased efficiency design of graphene membranes for gas separation and water desalination
Authors: Muraru Sorin , Ionita Mariana
Published: May 2020

The potential impact of climate change is widely known as having serious consequences. The themes of water desalination and gas separation are closely related to the environment and energy industry. Graphene-based membranes are promising filtration devices for the two tasks. This review aims to supply a comprehensive overview of the recent computational studies investigating the performance of graphene-based membranes used in water desalination or gas separation. With the use of computational methods, the literature covered finds evidence for key factors, such as pore shape and density, affecting the performance of the investigated membranes. The reviewed studies are expected to act as an impulse towards more computational studies and eventually actual design of graphene-based membranes for water desalination and gas separation.
Acquiring variable commands at home and abroad: Examining optatives and imperatives in L1 and L2 Spanish
Authors: Neumann Farrah , Kanwit Matthew
Published: May 2020

Since many linguistic structures are variable (i. e. conveyed by multiple forms), building a second-language grammar critically involves developing sociolinguistic competence (Canale and Swain. 1980. Theoretical bases of communicative approaches to second language teaching and testing. Applied Linguistics 1(1). 1–47), including knowledge of contexts in which to use one form over another (Bayley and Langman. 2004. Variation in the group and the individual: Evidence from second language acquisition. International Review of Applied Linguistics in Language Teaching 42(4). 303–318). Consequently, researchers interested in such competence have increasingly analyzed the study-abroad context to gauge learners’ ability to approximate local norms following a stay abroad, due to the quality and quantity of input to which learners may gain access (Lafford. 2006. The effects of study abroad vs. classroom contexts on Spanish SLA: Old assumptions, new insights and future research directions. In Carol Klee & Timothy Face (eds.), Selected proceedings of the 7th conference on the acquisition of Spanish and Portuguese as first and second languages, 1–25. Somerville, MA: Cascadilla Proceedings Project). Nevertheless, the present study is the first to examine native or learner variation between imperative (e. g. ven ‘come’) and optative Spanish commands (e. g. que vengas ‘come’). We first performed a corpus analysis to determine the linguistic factors to manipulate in a contextualized task, which elicited commands from learners before and after four weeks abroad in Alcalá de Henares, Spain. Their overall rates of selection and predictive factors were compared to local native speakers (NSs) and a control group of at-home learners.

Results revealed that the abroad learners more closely approached NS rates of selection following the stay abroad. Nonetheless, for both learner groups conditioning by independent variables only partially approximated the NS system, which was more complex than previously suggested.
Lack of hotspot mutations other than TP53 R249S in aflatoxin B1 associated hepatocellular carcinoma
Authors: Akyerli Cemaliye B. , Yüksel Şirin K. , Yakıcıer M. Cengiz
Published: May 2020

Objective

Despite the recent advances in diagnosis and treatment of hepatocellular carcinoma (HCC), it is still a major health problem. Therefore, understanding the molecular mechanism is very important. Our aim is to investigate the molecular basis of aflatoxin B1 (AFB1) induced HCC other than the hotspot TP53 p.Arg249Ser (c.747G>T) (R249S) mutation.

Methods

525 genes previously reported to be involved in carcinogenesis with mutations in different cancer types were analyzed by next generation sequencing for 525 cancer-gene panel (Roche/NimbleGen) in one tumor sample (T29) and one cell line (MAHLAVU) carrying TP53 R249S mutation. Additionally, ARID2 and BCORL1 genes were analyzed by Sanger sequencing for MAHLAVU and Primary Liver Carcinoma/Poliomyelitis Research Foundation/5 (PLC/PRF/5) cell lines.

Results

No other common gene mutations were found in the analyzed T29 and MAHLAVU samples and also no genetic variation possibly associated with AFB1 was detected in PLC/PRF/5 cell line and 68 COSMIC HCC samples. Likewise, no pathogenic mutation was detected in ARID2 and BCORL1 genes of MAHLAVU and PLC/PRF/5 cell lines.

Conclusion

No fingerprint mutations were detected in the analyzed genes. To the best of our knowledge, other hotspot mutations appear to be absent if not at a very low frequency in HCC carrying TP53 R249S mutation.
Die Vermittlung der Transzendenz in die Immanenz
Authors: Hannemann Tilman
Published: May 2020

Die gotische Kirchenarchitektur galt in der Religionsphänomenologie als ein Ideal für die Vermittlung von Transzendenz. Historisch betrachtet avancierte zunächst im religiösen Umfeld des Sturm und Drang der zeichenhafte ‚Thurm‘ des Straßburger Münster zu einer natursprachlichen Repräsentation von ,Wahrheit‘. Der Münsterturm wurde als Wahrnehmungsraum emotional codiert und eine kleine Pilgerpraxis entwickelte sich von 1770 bis 1780. Gut zwanzig Jahre später erneuerte Friedrich Schlegel im Zuge der deutschen Nationalbewegung die Rezeption der Gotik anhand des Kölner Doms.

Dieser Artikel rekonstruiert die mediale Funktion von Architektur im Zusammenhang dieser historischen Wahrnehmungsräume und historisiert den Transzendenzbegriff. Die Gestaltung religiöser Emotionen erfolgt im Austausch mit zeitgenössischen Theorien über Anschauung und Wahrnehmung. Welche architektonischen Motive standen für die Erfahrung von Transzendenz? Welche Sprachstrategien bezeugten eine erfolgreiche Vermittlung?
Kulturspezifischer Dualismus bei der Übersetzung griechischer Philosophie in die Chaldäischen Orakel hinein
Authors: Elsas Christoph
Published: May 2020

In dankbarer Erinnerung an Carsten Colpes Forschungen untersucht der Artikel Tradition und Translation an den als „heidnische Bibel“ oder „Weisheit Zoroasters“ sowie als kosmisch-mystisches Kritikpotential in Christentum und Islam bedeutsam gewordenen Chaldäischen Orakeln. Ich kann wechselseitige Anregungen zwischen den Chaldäischen Orakeln und der mittelplatonischen Religionsphilosophie des Numenios von Apameia um 180 n. Chr. zeigen: durch Möglichkeiten iranischen und griechischen Verständnisses von Dualismus sowie einerseits Orientalismus bei Numenios und andererseits Affinität zu Platon und Homer beim Theurgen Julian. Die Fragmente der Chaldäischen Orakel sind keine Originalzeugnisse aus Chaldäa oder des Zoroastrismus – aber Abwandlungen. Es gab die mesopotamische Priesterwissenschaft mit Divination um Ištar, die von zoroastrischen Priestern mit der gleichfalls Himmel und Erde verbindenden Wassergöttin Anâhitâ und im Römerreich mit Hekate als Zaubergöttin und beseelendem Prinzip identifiziert wurde.
Transparente Lieferketten per Gesetz

The current discussion about the sustainability and transparency of supply chains is characterized by conflicting positions. Whereas there is a widespread consensus that sustainable behavior of German companies in supply chains is necessary, the discussion about appropriate policy measures to enforce sustainability is still ongoing fiercely. The so-called development community insists on legal rprovisions with a strict enforcement mechanism and severe punishment. Others argue that such provisions will rather crowd out German companies of developing countries and leave the field to companies from countries where human rights and the environment play a minor role. In other words, it is doubted whether too strict requirements produce a backlash with respect to sustainability and transparency of supply chains in developing countries. The paper presents the arguments of this discussion and concludes that voluntary agreements are superior to legal provisions.
Da eine oder mehrere betroffen …

Based on a corpus study conducted using the GerManC corpus (1650–1800), the paper sketches the functional and sociosymbolic development of subordinate clause constructions introduced by the subjunctorda‘since’ in different text genres. In the second half of the 17thand the first half of the 18thcentury, thedaclauses were characterized by semantic vagueness: Besides temporal, spatial and causal relations, the subjunctor established conditional, concessive, and adversative links between clauses. The corpus study reveals that different genres are crucial to the readings ofdaclauses. Spatial and temporal usages, for example, occur more often in sermons than in other genres. The conditional reading, in contrast, strongly tends to occur in legal texts, where it displays very high frequency. This could be the reason whydaclauses carry indexical meaning in contemporary German and are associated with formal language. Over the course of the 18thcentury, the causal usages increase in all genres. Surprisingly, these causaldaclauses tend to be placed in front of the matrix clause despite the overall tendency of causal clauses to follow the matrix clause.
Untersuchungen zum deutschen Asylgesetz aus der funktionalen Satzperspektive
Authors: Pang Wenwei , Liu Ningning
Published: May 2020

Under the background of the current refugee crisis in Europe, Germany is undoubtedly playing an increasingly decisive role, which is why the substantive changes to German Asylum Act have attracted attention worldwide. In order to contribute to a better understanding of the information delivery and communication of the Asylum Act, this article analyzes the relevant paragraphs of this Act from a functional sentence perspective (FSP). By scrutinizing the influencing factors of the communicative dynamics (CD) of the Asylum Act, this article examines and clarifies how FSP participates in the communication of the Act. Besides tracking and assessing the related approach, varied types of results that can be achieved by functional analysis are particularly presented. This article hopes to produce some new insights into the FSP theory and shed light on future research directions for the applications of FSP.
