A new extreme value copula and new families of univariate distributions based on Freund’s exponential model
Authors: Guzmics Sándor , Pflug Georg Ch. 
Published: December 2020

Abstract
The use of the exponential distribution and its multivariate generalizations is extremely popular in lifetime modeling. Freund’s bivariate exponential model (1961) is based on the idea that the remaining lifetime of any entity in a bivariate system is shortened when the other entity defaults. Such a model can be quite useful for studying systemic risk, for instance in financial systems. Guzmics and Pflug (2019) revisited Freund’s model, deriving the corresponding bivariate copula and examined some characteristics of it; furthermore, we opened the door for a multivariate setting. Now we present further investigations in the bivariate model: we compute the tail dependence coefficients, we examine the marginal and joint distributions of the componentwise maxima, which leads to an extreme value copula, which – to the best of our knowledge – has not been investigated in the literature yet. The original bivariate model of Freund has been extended to more variables by several authors. We also turn to the multivariate setting, and our focus is different from that of the previous generalizations, and therefore it is novel: examining the distribution of the sum and of the average of the lifetime variables (provided that the shock parameters are all the same) leads to new families of univariate distributions, which we call Exponential Gamma Mixture Type I and Type II (EGM) distributions. We present their basic properties, we provide asymptotics for them, and finally we also provide the limiting distribution for the EGM Type II distribution.
On quantile based co-risk measures and their estimation
Authors: Fuchs Sebastian , Trutschnig Wolfgang 
Published: December 2020

Abstract
Conditional Value-at-Risk (CoVaR) is defined as the Value-at-Risk of a certain risk given that the related risk equals a given threshold (CoVaR=) or is smaller/larger than a given threshold (CoVaR</CoVaR≥). We extend the notion of Conditional Value-at-Risk to quantile based co-risk measures that are weighted mixtures of CoVaR at different levels and hence involve the stochastic dependence that occurs among the risks and that is captured by copulas. We show that every quantile based co-risk measure is a quantile based risk measure and hence fulfills all related properties. We further discuss continuity results of quantile based co-risk measures from which consistent estimators for CoVaR< and CoVaR≥ based risk measures immediately follow when plugging in empirical copulas. Although estimating co-risk measures based on CoVaR= is a nontrivial endeavour since conditioning on events with zero probability is necessary we show that working with so-called empirical checkerboard copulas allows to construct strongly consistent estimators for CoVaR= and related co-risk measures under very mild regularity conditions. A small simulation study illustrates the performance of the obtained estimators for special classes of copulas.
Time to Reduce Complexity in a Data-Driven Regulatory Agenda – Perspectives on the MiFID II Best Execution Regime
Authors: Krüger Andersen Peter 
Published: December 2020

The revised Markets in Financial Instruments Directive and Regulation (the MiFID II regime)See Directive 2014/65/EU (MiFID II) and Regulation (EU) 600/2014 (MiFIR). is one of the most comprehensive reforms of market structural and investor protection regimes the world has yet seen. The MiFID II regime will affect the European – and likely the global – market structure for years to come. Based on relevant perspectives from the revised best execution regime under MiFID II, this article suggest that it is time to reduce complexity. It is argued that unless a sufficient degree of horizontal and vertical integration of the best execution regulation takes place, the policy objectives cannot be reached. Further, it is argued that the significant data exercise that comes with the new rules only serves end-investors if a sufficient level of data consistency can be achieved. From this outset, the article emphasises the increased importance of data in today’s EU financial regulation. The article includes relevant comparisons to the equivalent US rules on best execution.
The Principle of Directive-Compliant Development of the Law and the Contra Legem Limit
Authors: Möllers Thomas M.J. 
Published: December 2020

Abstract
The Europeanisation of domestic law calls for a classical methodology to ‘update’ the established traditions of the law. The relationship between European directives and national law is difficult, since directives do apply, but European legal texts need to be implemented into national law. Whilst directives are not binding on private individuals, there is no direct third-party effect, but only an ‘indirect effect’. This effect is influenced by the stipulations of the ECJ, but is ultimately determined in accordance with methodical principles of national law. The ECJ uses a broad term of interpretation of the law. In contrast, in German and Austrian legal methodology the wording of a provision defines the dividing line between interpretation and further development of the law. The article reveals how legal scholars and the case-law have gradually shown in recent decades a greater willingness to shift from a narrow, traditional boundary of permissible development of the law to a modern line of case-law regarding the boundary of directive-compliant, permissible development of the law.
Effects of pulsed electric fields on sour cherry juice properties and formations of furfural and hydroxymethylfurfural
Authors: Akdemir Evrendilek Gulsun , Agcam Erdal , Akyildiz Asiye 
Published: December 2020

Abstract
Impacts of pulsed electric fields (PEF) on physicochemical properties, bioactive compounds, and furfural and hydroxymethylfurfural (HMF) formations were quantified for sour cherry juice (SCJ). pH, titratable acidity (TA), total soluble solids (TSS), a*, b*, chroma, and total monomeric anthocyanin content (TMAC) were not significantly affected by 0–0.0341 J/L. The initial total antioxidant capacity (TAC) significantly rose with all the PEF treatments but initial citric, malic, fumaric, oxalic, succinic (−)-epicatechin, ferrulic, gallic, luteolin, p-coumaric, and o-coumaric acids, Cy-3-sop, and Cy-3-glu did not significantly degrade with no formations of furfural and HMF. The best-fit regression models explained 60.1, 39.7, and 36.3% of variation in TAC, TMAC, and TSS, respectively. Frequency exerted a greater impact than did electric field strength (EFS) on TA, pH, TSS, total color difference (TCD), hue, chroma, TMAC, TAC, sinapic, oxalic, quinic and tartaric acids, Cy-3-glu-rut, and furfural formation. 350.9 µs, 6.78 kV/cm, and 98 Hz were pointed as optimal settings.
Anthropogenic climate change on a non-linear arctic sea-ice model of fractional Duffing oscillator
Authors: Eze Sunday C. 
Published: December 2020

Abstract
In this contribution, a non-linear arctic sea-ice model of fractional Duffing oscillator is given. The solution of the model was obtained using a new proposed analytical method, which is an elegant combination of asymptotic and Laplace methods. The result obtained showed that this method is a very powerful and efficient technique for finding the analytical solution of nonlinear fractional differential equation. From the analysis of the result, we observed that the impact of anthropogenic climate change on arctic sea-ice could lead to flooding in many coastal areas and low-lying island nations.
Tualang honey versus steroid impregnated nasal dressing following endoscopic sinus surgery: a randomized controlled trial
Authors: Kumarasamy Guhan , Ramli Ramiza Ramza , Singh Harvinder , Abdullah Baharudin 
Published: December 2020

Abstract

Objectives
Recurrence rate of nasal polyps is high following endoscopic sinus surgery. To improve the surgical outcome, steroid impregnated nasal dressing is used postoperatively We aimed to compare the effect of Tualang honey impregnated nasal dressing with steroid impregnated nasal dressing on wound healing and surgical outcomes in post endoscopic sinus surgery patients.

Methods
A prospective, randomized, controlled trial was carried out at two tertiary hospitals. 32 patients diagnosed with chronic rhinosinusitis and had underwent endoscopic sinus surgery were enrolled. The study group received 2 mL of Tualang honey nasal dressing and the control group received nasal dressing with 2 mL of triamcinolone 20 mg/mL as positive control. A 2 cm nasal dressing was placed longitudinally into the middle meatuses of both nasal cavities. Postoperative healing assessments of edema, crusting, secretions, scarring and symptoms were performed at postoperative day 7, 14, 28 and at 3 months using Sinonasal Outcome Test 22 questionnaire and modified Lund-Kennedy scoring system.

Results
There were no significant differences noted in the scores of Sinonasal Outcome Test 22 and modified Lund-Kennedy at Day 7, 14 and 28 (p>0.05) for both groups. At 3rd month, patients in the triamcinolone group had lesser symptoms and better endoscopic findings (p<0.05).

Conclusion
Tualang honey is not as effective as steroid in achieving good wound healing and surgical outcomes in post endoscopic sinus surgery patients. Thus, it is not suitable as a substitute for steroid to reduce symptoms and prevent recurrence of disease.
The co-treatment of rosuvastatin with dapagliflozin synergistically inhibited apoptosis via activating the PI3K/AKt/mTOR signaling pathway in myocardial ischemia/reperfusion injury rats
Authors: Gong Lei , Wang Xuyang , Pan Jinyu , Zhang Mingjun , Liu Dian , Liu Ming , Li Li , An Fengshuang 
Published: December 2020

Abstract

Objective
The purpose of the present study was to evaluate the role of co-treatment of rosuvastatin (RSV) and dapagliflozin (DGZ) preconditioning in myocardium ischemia/reperfusion (I/R) injury and to further investigate the underlying mechanism.

Methods
Sprague-Dawley (SD) rats (n = 25) were divided into five groups randomly: (1) Sham, (2) I/R, (3) I/R + RSV (10 mg/kg), (4) IR + DGZ (1 mg/kg), and (5) I/R + RSV (10 mg/kg) + DGZ (1 mg/kg). The I/R model was induced with 30 min of left anterior descending occlusion followed by 120 min of reperfusion.

Results

In vivo pretreatment with RSV and DGZ, respectively, showed a significant reduction of infarction size, a significant increase in the levels of left ventricular systolic pressure, and maximal rate increase in left ventricular pressure (+dp/dt
max), decrease in the levels of left ventricular end-diastolic pressure (LVEDP), maximal rate of decrease of left ventricular pressure (−dp/dt
max) and activity of cardiac enzymes of creatine kinase (CK), creatine kinase MB isoenzymes (CK-MB), and hyper-tensive cardiac troponin I compared with the I/R group. H9C2 cells were exposed to hypoxia/reoxygenation to simulate an I/R model. In vitro administration of 25 µM RSV and 50 µM DGZ significantly enhanced cell viability, upregulated the expression levels of p-PI3K, p-Akt, p-mTOR, and Bcl-2, whereas it downregulated cleaved-caspase3, Bax. TUNEL assay indicated that pretreatment with RSV and DGZ decreased the apoptosis of H9C2 cells.

Conclusion
The combination of RSV and DGZ significantly enhances the cardioprotective effects compared with RSV or DGZ alone. RSV and DGZ have the potential cardioprotective effects against I/R injury by activating the PI3K/AKt/mTOR signaling pathway.

Im Anschluss werden methodische und konzeptuelle Herausforderungen hervorgehoben, die mit der Erhebung und Erforschung des Klimas im Justizvollzug in Theorie und Praxis einhergehen. Aus diesen werden eine Reihe von Empfehlungen für die Klimaforschung im Justizvollzug abgeleitet und diskutiert.
“Es gibt nur eine Sprache”: The ‘Task of the Translator’ in Rosenzweig’s Idea of Language and Redemption. Its Conceptual Homologies and Expansions
Authors: De Villa Massimiliano 
Published: December 2020

Abstract
The concurrence of different languages is one of the tenets of Rosenzweig Sprachdenken and of his translation activity which finds its main theoretical explication in the afterword to his ‘Zweiundneunzig Hymnen und Gedichte des Yehuda Halevi’ (Konstanz, Wöhrle, 1924). In the afterword to the translation of ha-Levi’s lyrical corpus, Rosenzweig outlines a translation model which, trying to convey all the morphological, syntactic and lexical traits of the source language into the target language, gives way to a real linguistic fusion which defies the limits and boundaries of expression and opens onto a redemptive perspective. On the basis of this concluding note and of some passages from ‘The Star of Redemption’, the article tries to analyse Rosenzweig’s idea of language and of its nexus with the idea of redemption with reference to Walter Benjamin’s famous essay ‘The Task of the Translator’ and, as a point of convergence, with Paul Celan’s conception of poetic language.
Just West of East: The Paradoxical Place of the Theresienstadt Ghetto in Policy and Perception
Authors: Walch Teresa 
Published: December 2020

Abstract
When German authorities established the Theresienstadt Ghetto for Bohemian and Moravian Jews in late 1941, the site initially functioned much like other ghettos and transit camps at the time, as a mere way station to sites of extermination further East. The decision to reconfigure the ghetto as a site of internment for select “privileged” groups of Jews from Germany and Western Europe, and its advertisement as a “Jewish settlement” in Nazi propaganda, constituted an apparent paradox for a regime that sought to make the Greater German Reich “judenrein” (clean of Jews). This article investigates the Theresienstadt Ghetto from a historical-spatial perspective and argues that varying prejudices and degrees of antisemitism shaped divergent “spatial solutions” to segregate Jews from non-Jews, wherein the perceived divide between so-called “Ostjuden” and assimilated Western Jews played a central role. In this analysis, Theresienstadt emerges as a logical culmination to paradoxical policies designed to segregate select groups of German and assimilated Western European Jews.

Tractatus, Application and Use
Authors: van der Does Jaap , Stokhof Martin 
Published: December 2020

Abstract
The article argues for a contextualised reading of Wittgenstein’s Tractatus. It analyses in detail the role that use and application play in the text and how that supports a conception of transcendentality of logic that allows for contextualisation. The article identifies a tension in the text, between the requirement that sense be determinate and the contextual nature of application, and suggests that it is this tension that is a major driver of Wittgenstein’s later ideas.
Getting in touch with children with autism: Specialist guidelines for a touch-perceiving robot
Authors: Burns Rachael Bevill , Seifi Hasti , Lee Hyosang , Kuchenbecker Katherine J. 
Published: December 2020

Abstract
Children with autism need innovative solutions that help them learn to master everyday experiences and cope with stressful situations. We propose that socially assistive robot companions could better understand and react to a child’s needs if they utilized tactile sensing. We examined the existing relevant literature to create an initial set of six tactile-perception requirements, and we then evaluated these requirements through interviews with 11 experienced autism specialists from a variety of backgrounds. Thematic analysis of the comments shared by the specialists revealed three overarching themes: the touch-seeking and touch-avoiding behavior of autistic children, their individual differences and customization needs, and the roles that a touch-perceiving robot could play in such interactions. Using the interview study feedback, we refined our initial list into seven qualitative requirements that describe
robustness and maintainability
,
sensing range
,
feel
,
gesture identification
,
spatial
,
temporal
, and
adaptation
attributes for the touch-perception system of a robot companion for children with autism. Finally, by utilizing the literature and current best practices in tactile sensor development and signal processing, we transformed these qualitative requirements into quantitative specifications. We discuss the implications of these requirements for future human–robot interaction research in the sensing, computing, and user research communities.
Alternative Real Value Hybrid Model for the Valuation of Reversionary Leasehold Investment Properties
Authors: Ataguba Joseph Obaje 
Published: December 2020

Abstract
This study is a design of an alternative real value hybrid model for the valuation of reversionary leasehold investment properties characterized by divergence in the revision period of sub-rent and head rent respectively. The development of this model commenced with a synthesis of inputs for the modified rational- and real value hybrid models, and the derivation of an equivalent cash flow multiplier for terminal investments. With exception of the generic real value model, term incomes across all other contemporary models including the alternative real value hybrid model were discounted using the equated yield. The discounted reversionary cash flows in the valuation template associated with the alternative real value hybrid model appears identical to that in the generic real value model, while exhibiting itself as a surrogate reversionary income multiplier for the modified rational, and the real value/short-cut DCF models respectively. The alternative real value hybrid model was validated as capable of producing valuations that are identical to those churned out from all the existing contemporary models for the valuation of this category of reversionary leasehold investment property. The study is a novel attempt towards redesigning the modified rational model of leasehold investment property valuation and according it a real value perspective.
La troisième dimension — De la fonction éthique et esthétique du décor dans le théâtre de machines français du XVIIe siècle
Authors: Dickhaut Kirsten 
Published: December 2020

Abstract
The machine theatre in France achieves its peak in the second half of the seventeenth century. It is the construction of machines that permits the adequate representation of the third dimension on stage. This optical illusion is created by flying characters, as heroes, gods, or demons moving horizontally and vertically. The enumeration indicates that only characters possessing either ethically exemplary character traits or incorporating sin are allowed to fly. Therefore, the third dimension indicates bienséance – or its opposite. According to this, the following thesis is deduced: The machine theatre illustrates via aesthetic concerns characterising its third dimension an ethic foundation. Ethic and aesthetics determine each other in the context of both, decorum and in theatre practice. In order to prove this thesis three steps are taken. First of all, the machine theatre’s relationship to imitation and creation is explored. Second, the stage design, representing the aesthetic benefits of the machines in service of the third dimension, are explained. Finally, the concrete example of Pierre Corneille’s Andromède is analysed by pointing out the role of Pegasus and Perseus.
Der Dichter vor dem Porträt. Dichtung und Malerei um die Sonetti Benedetto Varchis
Authors: Vatteroni Selene Maria 
Published: December 2020

Abstract
Benedetto Varchi’s Due Lezzioni not only represent the high point of the debate on the paragone between painting and sculpture, but they also bring up the question of the comparison of painting and poetry. Building his argument on their common foundation in imitation, in the second lecture Varchi advocates the superiority of poetry over painting based on its mimetic capacity. My paper investigates this topic in Varchi’s sonnets, focusing on a rhetorically consistent series of poems addressed to the painter and poet Angolo Bronzino, with whom the poet enjoyed a close friendship, and culminating in a correspondence with the medalist Domenico Poggini. In these poems Varchi renovates the Petrarchan model of Rvf 77–78 by setting up a Neo-platonically based dialectic between dentro as the domain of poetry and fuori as the domain of painting, thereby shifting the comparison from the field of their mimetic capacity to that of their glorifying and immortalizing function.

Published: December 2020

Abstract

Objectives
To investigate the possible protective effects of resveratrol against oxidative testicular damage due to scattered radiation during pelvic ionizing radiation exposure in rats.

Methods
Rats were divided into 5 groups; control, radiation, and radiation + resveratrol therapy in early and late periods. Under anesthesia, 20 Gy ionizing radiation was applied to prostatic region. Resveratrol was administered (10 mg/kg/day) orally before ionizing radiation exposure. Animals were decapitated at the end of 1st and 10th weeks. Biochemical markers of oxidative stress; caspase-3 and sirtuin-1 protein expressions; testosterone levels were evaluated, histological examinations were performed.

Results
Significant increases in malondialdehyde, 8-hydroxy-deoxyguanosine levels, myeloperoxidase, and caspase-3 activities were observed after ionizing radiation exposure, also superoxide dismutase and glutathione activities were significantly decreased. Radiotherapy increased caspase-3 and decreased sirtuin-1 protein expressions. Resveratrol treatment significantly reversed these parameters and also reversed the decrease in testosterone levels back to control levels in late period.

Conclusion
Resveratrol showed antioxidant and sirtuin-activating properties against oxidative damage caused by scattered radiation to testis and provided hormonal protection. These results suggest that resveratrol may be an alternative protective agent on testicular tissues against the effects of scattered pelvic radiation.
