The Gini index is a measure of the inequality of a distribution that can be derived from Lorenz curves. While commonly used in, e.g., economic research, it suffers from ambiguity via lack of Lorenz dominance preservation. Here, investigation of large sets of empirical distributions of incomes of the World’s countries over several years indicated firstly, that the Gini indices are centered on a value of 33.33% corresponding to the Gini index of the uniform distribution and secondly, that the Lorenz curves of these distributions are consistent with Lorenz curves of log-normal distributions. This can be employed to provide a Lorenz dominance preserving equivalent of the Gini index. Therefore, a modified measure based on log-normal approximation and standardization of Lorenz curves is proposed. The so-called UGini index provides a meaningful and intuitive standardization on the uniform distribution as this characterizes societies that provide equal chances. The novel UGini index preserves Lorenz dominance. Analysis of the probability density distributions of the UGini index of the World’s counties income data indicated multimodality in two independent data sets. Applying Bayesian statistics provided a data-based classification of the World’s countries’ income distributions. The UGini index can be re-transferred into the classical index to preserve comparability with previous research.
The paper provides an updated checklist of the alien flora of Turkey with information on its structure. The alien flora of Turkey comprises 340 taxa, among which there are 321 angiosperms, 17 gymnosperms and two ferns. Of the total number of taxa, 228 (68%) are naturalized and 112 (32%) are casual. There are 275 neophytes (172 naturalized and 103 casual) and 61 archaeophytes (52 naturalized and 9 casual); four species could not be classified with respect to the residence time. In addition, 47 frequently planted taxa with a potential to escape are also listed. The richest families are Asteraceae (38 taxa), Poaceae (30), Fabaceae (23) and Solanaceae (22). As for the naturalized alien plants, the highest species richness is found in Asteraceae (31 taxa), Poaceae (22), Amaranthaceae (18) and Solanaceae (15). The majority of alien taxa are perennial (63.8% of the total number of taxa with this life history assigned, including those with multiple life histories), annuals contribute 33.8% and 2.4% are biennial aliens. Among perennials the most common life forms are phanerophytes, of which 20.3% are trees and 12.6% shrubs; woody vines, stem succulents, and aquatic plants are comparatively less represented. Most of the 340 alien taxa introduced to Turkey have their native ranges in Americas (44.7%) and Asia (27.6%). Of other regions, 9.1% originated in Africa, 4.4% in Eurasia, 3.8% in Australia and Oceania and 3.5% in the Mediterranean. The majority of taxa (71.9%) were introduced intentionally, whereas the remaining (28.1%) were introduced accidentally. Among the taxa introduced intentionally, the vast majority are ornamental plants (55.2%), 10.0% taxa were introduced for forestry and 6.7% as crops. Casual alien plants are most commonly found in urban and ruderal habitats (40.1%) where naturalized taxa are also often recorded (27.3%). Plants that occur as agricultural weeds are typically naturalized rather than casual (16.0% vs 7.1%, respectively). However, (semi)natural habitats in Turkey are often invaded by alien taxa, especially by those that are able to naturalize.
Kurt Oppert hat, vor allem gestützt auf Rilkes "Neue Gedichte", die Verbreitung der Bezeichnung 'Dinggedicht' initiiert. Obwohl die Forschung längst die Inadäquatheit der meisten Charakteristika, die Oppert unter anderem aus Rilkes Dinggedichten zu destillieren versuchte, herausgearbeitet hat, ist die Bezeichnung noch immer weit verbreitet. Aus guten Gründen, wie die folgende Analyse von "Die Flamingos" vor dem Hintergrund von Rilkes nuancierten kunsttheoretischen Reflexionen des Dingbegriffs zeigen wird.
Allerdings haften der vielfach rejustierten Typusbezeichnung 'Dinggedicht' noch immer hartnäckig und nicht immer offensichtlich Reste einer intuitiven Konstellation von 'Ding' und lyrischem Sprechen an, die einst das Zentrum von Opperts Überlegungen gebildet hatte. Es ist daher das Projekt dieses Beitrags, Rilkes Arbeit an einem neuen, andersartigen Verhältnis von 'Gedicht' und 'Ding' freizulegen. Oppert versteht das 'Dinggedicht' als einen "Gegentypus" zu Goethes "werdende[m] Gedicht mit seiner subjektiven, echt lyrischen Stimmungshandlung ", "der auf unpersönliche, episch-objektive Beschreibung eines Seienden angelegt ist".
This study compares the dramas König Ottokars Glück und Ende by the Austrian dramatist Franz Grillparzer and Král Přemysl Otakar Druhý by the Czech writer František Zavřel. The focus is on the character of the Bohemian King Otakar II. The king is depicted by both authors as a strong and remarkable figure, but while Grillparzer presents him as an anti-hero who falls victim to his own ruthless politics, Zavřel shows him to be a form of superman, whose downfall is caused by the pettiness of those around him. The study explores these differences and seeks to explain their origins
Androgen receptor deregulation drives bromodomain-mediated chromatin alterations in prostate cancer
(2017)
Global changes in chromatin accessibility may drive cancer progression by reprogramming transcription factor (TF) binding. In addition, histone acetylation readers such as bromodomain-containing protein 4 (BRD4) have been shown to associate with these TFs and contribute to aggressive cancers including prostate cancer (PC). Here, we show that chromatin accessibility defines castration-resistant prostate cancer (CRPC). We show that the deregulation of androgen receptor (AR) expression is a driver of chromatin relaxation and that AR/androgen-regulated bromodomain-containing proteins (BRDs) mediate this effect. We also report that BRDs are overexpressed in CRPCs and that ATAD2 and BRD2 have prognostic value. Finally, we developed gene stratification signature (BROMO-10) for bromodomain response and PC prognostication, to inform current and future trials with drugs targeting these processes. Our findings provide a compelling rational for combination therapy targeting bromodomains in selected patients in which BRD-mediated TF binding is enhanced or modified as cancer progresses.
This paper discusses aspects of direct speech in James Joyce’s story "The Sisters". The story is often analyzed with special attention to the gaps and ellipses in the utterances, which are usually read as omissions, evasions, or uncomfortable silences, and thus as indicative of some transgressive behaviour of the dead priest who is at the centre of the dialogues. In this article we explore the hypothesis that the utterances in question show features that are quite common in natural spoken language and thus may also be read as literary techniques to create authentic oral discourse. This hypothesis is not intended to invalidate previous interpretations, but to introduce an additional aspect of interpretation that has been neglected so far. In the context of a literary work, features of natural spoken language acquire new meaning, and the very attempt to narrow the gap between literary and natural spoken language appears as inauthentic, ominous and as an artistic strategy to express the unspeakable. The story thus evokes suspicion and a feeling of eeriness while also offering narrative and linguistic information that allows for a more empathic assessment of the characters. We use quantitative methods of analysis and linguistic data from corpora of (authentic) spoken language to substantiate our hypothesis. As "The Sisters" is a rather short story and the present study is, in several respects, exploratory, our claims and hypotheses need to be confirmed and validated by more exhaustive research into Joyce’s major works.
Mit Baltasar Gracián vertrauten Walter Benjamin-Lesern fällt sofort auf, dass der letzte und abschließende Abschnitt von Benjamins Ursprung des deutschen Trauerspiels einen unverkennbar Gracián’schen Titel trägt: "Ponderación mysteriosa". Als fremdartiges und rätselhaftes Bruchstück stehen die spanischen Vokabeln im deutschen Text. Lange Zeit wurden sie übersehen oder in Benjamins Reflexionen subsumiert. Bernd Witte deutet in seinem Kommentar zum Trauerspielbuch die Figur der 'ponderación misteriosa' als "Sinnbild für Benjamins eschatologische Zuversicht: 'Subjektivität, die wie ein Engel in die Tiefe niederstürzt, wird von Allegorien eingeholt und wird am Himmel, wird in Gott durch 'Ponderación mysteriosa' festgehalten'". Für Witte verdichtet diese Figur den theologischen Gehalt des Trauerspielbuches, zugleich zeigt sie aber auch die "Fragwürdigkeit seines literarischen Anspruches". Mit diesem Urteil sieht Witte nicht nur Benjamins Theorie des Trauerspiels und der Allegorie als wenig bedeutsam an, sondern erschwert zudem den Zugang zu einem der produktivsten Momente der Rezeptionsgeschichte von Graciáns 'ponderación misteriosa' im 20. Jahrhundert.
Walter Greiner: in memoriam
(2017)
Walter Greiner (29 October 1935 - 6 October 2016) was a German theoretical physicist. His scientific research interests include the thematic areas of atomic physics, heavy ion physics, nuclear physics, elementary particle physics (particularly quantum electrodynamics and quantum chromodynamics). He is most known in Germany for his series of books in theoretical physics, but he is also well known around the world. Greiner was born on October 29, 1935, in Neuenbau, Sonnenberg, Germany. He studied physics at the University of Frankfurt (Goethe University in Frankfurt Am Main), receiving in this institution a BSci in physics and a Master’s degree in 1960 with a thesis on plasma-reactors, and a PhD in 1961 at the University of Freiburg under Hans Marshal, with a thesis on the nuclear polarization in μμ-mesic atoms. During the period of 1962 to 1964 he was assistant professor at the University of Maryland, followed by a position as research associate at the University of Freiburg, in 1964. Starting in 1965, he became a full professor at the Institute for Theoretical Physics at Goethe University until 2003. Greiner has been a visiting professor to many universities and laboratories, including Florida State University, the University of Virginia, the University of California, the University of Melbourne, Vanderbilt University, Yale University, Oak Ridge National Laboratory and Los Alamos National Laboratory. In 2003, with Wolf Singer, he was the founding Director of the Frankfurt Institute for Advanced Studies (FIAS), and gave lectures and seminars in elementary particle physics. He died on October 6, 2016 at the age of 80.
Walter Greiner was an excellent teacher, researcher, friend. And he was a great supporter of the series of events known by the acronyms IWARA - International Workshop on Astronomy and Relativistic Astrophysics, STARS - Caribbean Symposium on Cosmology, Gravitation, Nuclear and Astroparticle Physics, and SMFNS - International Symposium on Strong Electromagnetic Fields and Neutron Stars. Walter Greiner left us. But his memory will remain always alive among us who have had the privilege of knowing him and enjoy his wisdom and joy of living.
It is with great joy and imbued with the contagious Christmas spirit lived in Macaronesia that I present the second issue of the sixth volume of this journal. This issue consolidates the new path tracked the beginning of 2016, which focused on the renewal of the editorial board and the broadening of the scope of the journal to new scientific areas.
É com grande alegria, e imbuída do contagiante espírito Natalício que se vive na Macaronésia, que apresento o segundo número do sexto volume desta revista. Este número consolida o novo rumo traçado no início de 2016, que apostou na renovação do corpo editorial e na ampliação do âmbito da revista para novas áreas científicas.
The efficacy of antiviral treatment for chronic hepatitis C virus (HCV) infection is determined by measuring HCV RNA at specific time points throughout therapy using highly sensitive and accurate HCV RNA assays. This study compared the performances of two recently developed real-time PCR HCV RNA assays, cobas HCV for use on the cobas 6800/8800 systems (cobas 6800/8800 HCV) and cobas HCV for use on the cobas 4800 system (cobas 4800 HCV), with those of two established assays, the Cobas AmpliPrep/Cobas TaqMan HCV quantitative test, version 2 (CAP/CTM v2) and the Cobas TaqMan HCV test, version 2 for use with the High Pure system (HPS/CTM v2). The limits of detection (LODs) and linearity at lower concentrations (5 to 1000 IU/ml) were assessed for cobas 6800/8800 HCV and cobas 4800 HCV using WHO standard traceable panels representing HCV genotypes (GT) 1 to 4. Pairwise assay comparisons were also performed using 245 clinical samples representing HCV GT 1 to GT 4. Results from cobas 6800/8800 HCV and cobas 4800 HCV were linear at low HCV RNA concentrations (<0.3 log10 IU/ml difference between expected and observed results) with LODs of 8.2 IU/ml and 11.7 IU/ml, respectively, for GT 1. The new assays showed excellent agreement with results from CAP/CTM v2 and HPS/CTM v2 in samples with quantifiable viral loads. The concordances using the 6 million IU/ml cutoff were high among all four assays (90 to 94%). In conclusion, the cobas 6800/8800 HCV and cobas 4800 HCV tests are sensitive and linear and correlate well with the established Roche assays used in clinical practice.
Sphingosine-1-phosphate (S1P) lyase irreversibly cleaves S1P, thereby catalysing the ultimate step of sphingolipid degradation. We show here that embryonic fibroblasts from S1P lyase-deficient mice (Sgpl1−/−-MEFs), in which S1P and sphingosine accumulate, have features of Niemann-Pick disease type C (NPC) cells. In the presence of serum, overall cholesterol content was elevated in Sgpl1−/−-MEFs, due to upregulation of the LDL receptor and enhanced cholesterol uptake. Despite this, activation of sterol regulatory element-binding protein-2 was increased in Sgpl1−/−-MEFs, indicating a local lack of cholesterol at the ER. Indeed, free cholesterol was retained in NPC1-containing vesicles, which is a hallmark of NPC. Furthermore, upregulation of amyloid precursor protein in Sgpl1−/−-MEFs was mimicked by an NPC1 inhibitor in Sgpl1+/+-MEFs and reduced by overexpression of NPC1. Lysosomal pH was not altered by S1P lyase deficiency, similar to NPC. Interestingly, lysosomal Ca2+ content and bafilomycin A1-induced [Ca2+]i increases were enhanced in Sgpl1−/−-MEFs, contrary to NPC. These results show that both a primary defect in cholesterol trafficking and S1P lyase deficiency cause overlapping phenotypic alterations, and challenge the present view on the role of sphingosine in lysosomal Ca2+ homeostasis.
Die heutige Situation im slowakischen Schulwesen ist sehr kompliziert. Das ist eine Folge der langjährigen Interessenlosigkeit der Regierung, die ab und zu durch absurde Reformen überdeckt wurde. Bis bestimmte Prioritäten gegen die ständige Fluktuation von Ministern für Schulwesen und die damit verbundene Sprachideologie nicht geschützt werden, werden wir immer Zeugen der ausgeübten Gewalt gegen bestimmte Fremdsprachen sein. Deshalb sollte eine der Prioritäten des Schulwesens die Beständigkeit bestimmter Gesetze und Maßnahmen unabhängig von den personalen Veränderungen in der Regierung werden. Bis zu dieser Zeit sollten wir, Deutschlehrer_innen, aber auch alle anderen Menschen, denen das Schicksal des Deutschen nicht gleichgültig ist, anhand von anderen Mitteln (z.B. auch von den oben erwähnten) weiter kämpfen.
Background: Taxonomy offers precise species identification and delimitation and thus provides basic information for biological research, e.g. through assessment of species richness. The importance of molecular taxonomy, i.e., the identification and delimitation of taxa based on molecular markers, has increased in the past decade. Recently developed exploratory tools now allow estimating species-level diversity in multi-locus molecular datasets.
Results: Here we use molecular species delimitation tools that either quantify differences in intra- and interspecific variability of loci, or divergence times within and between species, or perform coalescent species tree inference to estimate species-level entities in molecular genetic datasets. We benchmark results from these methods against 14 morphologically readily differentiable species of a well-defined subgroup of the diverse Drusinae subfamily (Trichoptera, Limnephilidae). Using a 3798 bp (6 loci) molecular data set we aim to corroborate a geographically isolated new species by integrating comparative morphological studies and molecular taxonomy.
Conclusions: Our results indicate that only multi-locus species delimitation provides taxonomically relevant information. The data further corroborate the new species Drusus zivici sp. nov. We provide differential diagnostic characters and describe the male, female and larva of this new species and discuss diversity patterns of Drusinae in the Balkans. We further discuss potential and significance of molecular species delimitation. Finally we argue that enhancing collaborative integrative taxonomy will accelerate assessment of global diversity and completion of reference libraries for applied fields, e.g., conservation and biomonitoring.
The article presents the first German-Czech handbook and textbook about forestry (written by Wenzel Elias Lenhardt). The text is of particular interest due to the language situation and the practical use of both German and Czech in the Bohemian Crown Lands during the 18th century. The paper also discusses several aspects of the handbook and textbook - including the author and the addressee from a pragmalinguistic perspective - and summarizes the results of an analysis of its textual characteristics, writing style, syntax and lexis.
According to general doctrine canceroselectivity of Cyclophosphamide is based on different activities of the 4-hydroxycyclophosphamide (OHCP) detoxifying cellular enzyme aldehyde dehydrogenase in tumor and normal cells. Aldehyde dehydrogenase converts the OHCP tautomere aldophosphamide (ALDO) to the non-cytotoxic carboxyphosphamide. Due to different activities of the detoxifying enzyme more cytotoxic phosporamide mustard (PAM) is spontaneously released from OHCP/ALDO in tumor cells. PAM unfolds its cytotoxic activity by forming intrastrand and interstrand DNA crosslinks. This hypothesis is supported by in vitro experiments which show inverse correlations of aldehyde dehydrogenase activity and sensitivity of tumor cells against activated congeners of cyclophosphamide like mafosfamide which hydrolyses within a few minutes to OHCP. In protein free rat serum ultrafiltrate however free OHCP and its coexisting tautomer ALDO are stable compounds. Its half-life in protein free rat serum ultrafiltrate (pH7, 37oC) is more than 20 h. Contrary to protein free ultrafiltrate in whole serum ALDO is enzymatically decomposed to PAM and 3-hydroxypropionaldehyde (HPA) within minutes. The decomposing enzyme was identified as 3´-5´ phosphodiesterase, the Michaelis constant was determined to be 10-3 M in human serum.
The experiments presented clearly demonstrate that ALDO is not only cleaved base catalyzed yielding acrolein and PAM but also cleaved enzymatically by serum phosphodiesterases yielding HPA and PAM. It is discussed that the reason of the high canceroselectivity of cyclophosphamide is not only due to enrichment of OHCP/ALDO in tumor cells due to less detoxification of ALDO in tumor cells than in normal cells. It is discussed that there is a good reason for an additional mechanism namely the amplification of apoptosis of PAM damaged cells by HPA.
A two step mechanism for the mechanism of action of OHCP/ALDO is discussed. During the first step, the DNA is damaged by alkylation by PAM. During the second step the cell containing damaged DNA is eliminated by apoptosis, supported by HPA.
Kaum hat der Bundestag das Gesetz über die Öffnung der Ehe beschlossen, wird es schon verfassungsrechtlich diskutiert. Dass das Bundesverfassungsgericht es für verfassungswidrig erklären wird, ist wenig wahrscheinlich. Und das lässt sich auch ohne Rückgriff auf den historischen Willen des Verfassungsgebers überzeugend begründen.
Fällt nach der Einführung der Ehe für alle der grundgesetzliche und der zivilrechtliche Ehebegriff auseinander? Das wäre nicht nur für die Ehe für alle als eine politische Errungenschaft, sondern auch für das Grundgesetz selbst ausgesprochen unglücklich. Wenn der Gesetzgeber in diesem Sinne die Ehe für alle öffnet, kann das dementsprechend den verfassungsrechtlichen Ehebegriff nicht unberührt lassen.
