    Uncertainty principles connected with the Mobius inversion formula

    No full text
    We say that two arithmetic functions ff and gg form a \emph{M\"{o}bius pair} if f(n)=dng(d)f(n) = \sum_{d \mid n} g(d) for all natural numbers nn. In that case, gg can be expressed in terms of ff by the familiar M\"{o}bius inversion formula of elementary number theory. In a previous paper, the first-named author showed that if the members ff and gg of a M\"{o}bius pair are both finitely supported, then both functions vanish identically. Here we prove two significantly stronger versions of this uncertainty principle. A corollary of our results is that in a nonzero M\"{o}bius pair, one cannot have both $\sum_{f(n) \neq 0}\frac{1}{n

    A red plait. Martin Pollack: Skażone krajobrazy. Przeł. Karolina Niedenthal. Wołowiec, Wydawnictwo Czarne, 2014, ss. 112. The present essay is devoted to a book by Martin Pollack entitled Skażone krajobrazy. In this volume the Austrian reporter and essayist creates a peculiar map of Central and EasternEurope. The former includes the sites of mass murders which were perpetrated in strict secrecy, and which until today have not been commemorated. Pollack argues that until this happens, the perpetrators who attempted at all costs to commit their crimes without any witnesses will prevail. A separate trait of Pollack’s essay has to do with a reflection about the “topography of terror”: the author presents with a poet’s devotion the landscapes in which acts of genocide were perpetrated. This enables the readers to examine the process of the Shoah from yet another perspective – a post‑anthropocentric perspective

    The difficult legacy and the obligation to remember in the "Topography of Remembrance" by Martin Pollack

    Der Beitrag beschäftigt sich mit den im Band "Topografie der Erinnerung" (2016) gesammelten Essays, die eine Auseinandersetzung Martin Pollacks mit der Erinnerung an seine Nazi-Vorfahren, vor allem an seinen Vater – SS-Sturmbahnführer, sind. Es werden folgende Fragen gestellt: Welche Bedeutung hat es für Pollack, Sohn eines Nazi-Verbrechers zu sein? Warum und aus welcher Perspektive schreibt er? Für wen macht er das? Wie verhält er sich dem Bild seines Vaters gegenüber? Die Antworten auf diese Fragen basieren auf einem theoretischen Diskurs über das Familiengedächtnis. Die These des Beitrags lautet, dass es Pollack nicht gelingt, in seinen Texten sich vom Vater zu distanzieren und objektiv zu schreiben. Er überlegt, was dies für seine eigene Identität bedeuten kann.Artykuł dotyczy esejów zebranych w tomie "Topografia pamięci" (2016) zajmujących się pamięcią Martina Pollacka o jego nazistowskich przodkach, zwłaszcza o jego ojcu – SS-manie. Autorka stawia następujące pytania: Jakie znaczenie ma dla Pollacka bycie synem nazistowskiego zbrodniarza? Dlaczego i z jakiej perspektywy pisze? Dla kogo to robi? Jak odnosi się do obrazu swojego ojca? Odpowiedzi na te pytania opierają się na teoretycznym dyskursie na temat pamięci rodzinnej i wynika z nich, że Pollack w swoich tekstach nie dystansuje się od swojego ojca i nie pisze obiektywnie, lecz pozostaje subiektywny w swojej narracji. Martwi go, że jest bezpośrednim potomkiem narodowych socjalistów i zastanawia się, co to może oznaczać dla jego własnej tożsamości.The article analyses essays collected in the volume "Topography of Remembrance" (2016) dealing with the memories of Martin Pollack about his Nazi ancestors, especially about his father who was an SS-man. The author of this article asks the following questions: What does it mean for Pollack to be the son of a Nazi criminal? Why and from what perspective is he writing? Who is he writing for? How does he relate to his father’s image? The answers to these questions are based on theoretical discourses on family memory. The thesis of the article is that Pollack does not distance himself from his father in his texts and does not write objectively but remains subjective in his narrative. He is concerned by the fact that he is a direct descendant of the National Socialists and he wonders what that might mean for his own identity

    Identification of the glutamine residue that may be involved in the transglutaminase-mediated intramolecular crosslinking of carp and walleye pollack myosin

    In order to elucidate the molecular mechanism of transglutaminase-mediated myosin cross-linking, a fluorescent monodansylcadaverine (MDC) was incorporated into carp Cyprinus carpio myosin and the reactive Gln residues were analyzed by cyanogen bromide cleavage. The fluorescence was predominantly detected in a 10.5 kDa BrCN-fragment, which is assumed to be located in subfragment 2 of the myosin heavy chain. Furthermore, lysyl endopeptidase digestion of the 10.5 kDa fragment revealed that MDC was specifically incorporated into the 520th Gln residue of the subfragment 2 domain. When meat paste prepared from walleye pollack Theragra chalcogramma frozen surimi was incubated with MDC, the fluorescence was mostly observed in a 16 kDa BrCN-fragment and also slightly detected in other three bands. By the digestion of 16 kDa fragment with lysyl endopeptidase, it was elucidated that MDC was incorporated specifically into Gln-520 of myosin subfragment 2, as well as detected in carp. This domain around Gln-520 is likely to be a common critical region for dimer formation of myosin heavy chains for both fish species. In walleye pollack, other reactive Gln residues are presumed to be exist in the C-terminus of the light meromyosin. This slight difference may be significant in a capacity to form tetramers or even larger multimers

    Eudora Welty and politics did the writer crusade?

    No full text
    This collection of complementary and interrelated essays by ten well-known Welty critics brings clarification to the controversial subject of Eudora Welty and the political. As the essays prove, Welty has been inaccurately assessed by critics from Diana Trilling in the Nation (1943) to Claudia Roth Pierpont in the New Yorker (1998) as a writer who avoids political, historical, or cultural engagement in her fiction. The better question these essayists explore is not whether but how Welty's work is to be understood as political. Harriet Pollack, Suzanne Marrs, Peggy Prenshaw, Noel Polk, Suzan Harrison, Ann Romines, Rebecca Mark, Barbara Ladd, Sharon Baris, and Daniele Pitavy-Souques place Welty's seeming rejection of the political in her 1961 essay "Must the Novelist Crusade?" into the cultural and historical context of 1940-1960. Welty, though she repudiated the concept of fiction as editorial, wrote stories that were inherently and unavoidably political. As the only living author to be reedited by the Library of America in its great American writers series, Eudora Welty deserves a sound appreciation of her complex oeuvre. Eudora Welty and politics provides just that, approaching Welty's work from an all-new point of view

    Intentions And Information In Discourse

    No full text
    This paper is about the flow of inference between communicative intentions, discourse structure and the domain during discourse processing. We augment a theory of discourse interpretation with a theory of distinct mental attitudes and reasoning about them, in order to provide an account of how the attitudes interact with reasoning about discourse structure. INTRODUCTION The flow of inference between communicative intentions and domain information is often essential to discourse processing. It is well reflected in this discourse from Moore and Pollack (1992): (1)a. George Bush supports big business. b. He's sure to veto House Bill 1711. There are at least three different interpretations. Consider Context 1: in this context the interpreter I believes that the author A wants to convince him that (1b) is true. For example, the context is one in which I has already uttered Bush won't veto any more bills. I reasons that A's linguistic behavior was intentional, and therefore that A believ..
