Quantum Auctions: Facts and Myths
No full textQuantum game theory, whatever opinions may be held due to its abstract physical formalism, have already found various applications even outside the orthodox physics domain. In this paper we introduce the concept of a quantum auction, its advantages and drawbacks. Then we describe the models that have already been put forward. A general model involves Wigner formalism and infinite dimensional Hilbert spaces - we envisage that the implementation might not be an easy task. But a restricted model advocated by the Hewlett-Packard group (Hogg et al) seems to be much easier to implement. We focus on problems related to combinatorial auctions and technical assumptions that are made. Powerful quantum algorithms for finding solutions would extend the range of possible applications. Quantum strategies, being qubits, can be teleported but are immune from cloning - therefore extreme privacy of agent's activity could in principle be guaranteed. Then we point out some key problem that have to be solved before commercial use would be possible. With present technology, optical networks, single photon sources and detectors seems to be sufficient for experimental realization in the near future.
Eine intermediale Literaturadaption: »Sandmann« von M. Mikolajczak und J. Piotrowski
No full text»Die Graphic Novel [...] ist wahrscheinlich die einzige Kunstform, die als Kind unserer Zeit betrachtet werden kann«, behauptet der italienische Essayist und Journalist Goffredo Fofi, der die Aktualität, die Vielfalt und die expressive Freiheit der sogenannten ‚neunten Kunst‘ (A. Tosti) betont. In dieser Hinsicht erweist sich Sandmann (2019) von M. Mikolajczak und J. Piotrowski als besonders geeignet, das innovative und intermediale Potenzial des Literatur-Comics zu demonstrieren.
Diese Graphic Novel zeichnet sich durch einen zugleich eng gefassten und originellen Umgang mit dem Ausgangstext aus, wie die Rückseite des Buchs ankündigt, wo die Adaption als »fiktive Fortsetzung, [...] Gruselgeschichte und Psychothriller« bezeichnet wird. Inhaltliche und sprachliche Fragmente von E. T. A. Hoffmanns Text werden mit Erfindungen auf bildlicher und textueller Ebene kreativ ‚montiert‘, ebenso wie auf der Ebene der Figuren, deren Charakterisierung und Funktionalisierung. Die Perspektivierung und die Erzählstrategien wurzeln in der Erzählung, weichen aber auch deutlich von ihr ab, um Themenbereiche wie z. B. Psychopathie und Erotik zu stärker hervorzuheben, die das Werk für zeitgenössische und nicht unbedingt spezifisch vorgebildete Rezipienten attraktiver werden lassen.
Höchst interessant sind außerdem sowohl die bildlichen Bezugnahmen auf Filme des Expressionismus wie Nosferatu und Das Cabinet des Dr. Caligari ‒ die Sandmann mit früheren Literatur-Comics wie Dino Battaglias Olimpia (1970) verbinden ‒, als auch Anklänge an allgemein bekannte Gruselfiguren wie das Monster in Alien oder Gollum in Der Herr der Ringe. Bildzitate in Literatur-Comics bilden außerdem »ein Scharnier zwischen der Comic-Geschichte und der Kunst-Geschichte« (M. Schmitz-Emans), wie auch Sandmann beweist, indem Stilisierungen von Gemälden u. a. von Botticelli, Schiele und Gauguin das Bildgedächtnis des Lesers herausfordern. Das Auge herrscht auf allen Ebenen vor.
Die originelle und fesselnde Montage von Bild- und Textzitaten in dieser Graphic Novel wirkt bisweilen desorientierend, doch die Kenntnis des ‚Hypotextes‘ (G. Genette) dient als hilfreicher Kompass für diejenigen Rezipienten, die Nathanael und Coppelius in die Tiefe des Textes begleiten wollen. »Adaptation is a form of repetition without replication« (L. Hutcheon): Sandmann von M. Mikolajczak und J. Piotrowski ist ein überzeugender Beweis dafür
Large eddy simulations of weakly heated stratocumulus top boudary layer
No full textPerforming Large Eddy Simulations (LES) of marine stratocumulus in the weakly heated boundary layer is an opportunity to evaluate the relative importance of radiative cooling and of a wind shear in cloud top region on cloud structure. It is shown that cooling due to longwave radiation influences the convective circulation in the atmospheric boundary layer and counteracts dilution caused by the wind shear

Towards a quantitative research framework for historical disciplines
No full textThe ever-expanding wealth of digital material that researchers have at their disposal today, coupled with growing computing power, makes the use of quantitative methods in historical disciplines in- creasingly more viable. However, applying exist- ing techniques and tools to historical datasets is not a trivial enterprise (Piotrowski, 2012; McGillivray, 2014). Moreover, scholarly communities react dif- ferently to the idea that new research questions and insights can arise from quantitative explorations that could not be made using purely qualitative ap- proaches. Some of them, such as linguistics (Jenset and McGillivray, 2017), have been acquainted with quantitative methods for a longer time. Others, such as history, have seen a growth in quantitat- ive methods on the fringes of the discipline, but have not incorporated them into the mainstream of scholarly practice (Hitchcock, 2013)
Plugged in: How media attract and affect youth
No full textNow, as never before, young people are surrounded by media—thanks to the sophistication and portability of the technology that puts it literally in the palms of their hands. Drawing on data and empirical research that cross many fields and continents, authors Valkenburg and Piotrowski examine the role of media in the lives of children from birth through adolescence, addressing the complex issues of how media affect the young and what adults can do to encourage responsible use in an age of selfies, Twitter, Facebook, and Instagram. This important study looks at both the sunny and the dark side of media use by today’s youth, including why and how their preferences change throughout childhood, whether digital gaming is harmful or helpful, the effects of placing tablets and smartphones in the hands of toddlers, the susceptibility of young people to online advertising, the legitimacy of parental concerns about media multitasking, and more. Patti M. Valkenburg is a university distinguished professor of media, youth, and society at the University of Amsterdam. Jessica Taylor Piotrowski is associate professor of youth and media entertainment at the University of Amsterdam

Treatment-integrated imaging, radiomics, and personalised radiotherapy: the future is at hand
No full textSince the introduction of computed tomography for planning purposes in the 1970s, we have been observing a continuous development of different imaging methods in radiotherapy. The current achievements of imaging technologies in radiotherapy enable more than just improvement of accuracy on the planning stage. Through integrating imaging with treatment machines, they allow advanced control methods of dose delivery during the treatment. This article reviews how the integration of existing and novel forms of imaging changes radiotherapy and how these advances can allow a more individualised approach to cancer therapy. We believe that the significant challenge for the next decade is the continued integration of a range of different imaging devices into linear accelerators. These imaging modalities should show intra-fraction changes in body morphology and inter-fraction metabolic changes. As the use of these more advanced, integrated machines grows, radiotherapy delivery will become more accurate, thus resulting in better clinical outcomes: higher cure rates with fewer side effects

Symbol (in / of) cutting age
No full textWith reference to the idea of postmodern culture which uses the episteme of tmesis, I attempt to consider in its context the status of symbol. Even if the Nietzschean programme of suspension of symbolization processes is preached, the desymbolization – forced by the Cutting Age – cannot succeed. By distinguishing various types of symbolization based on the concepts of tekmérion, tekmar and eikos, I show that the postmodern cut makes a paradoxical synthesis of those types and it does not violate the identity of symbol, because symbol as a unit (sym-bállica) implies some dichotomisation. Referring to Carl Gustav Jung, who referred to a ceremony of reconstructing an ape, I find the most spectacular manifestation of this symbolization in the attempts at dehumanization and demonization of Barack Obama's person.Akademia Sztuk Pięknych w ŁodziBarthes Roland, L'aventure sémiologique, Paris 1985.Barthes Roland, Przyjemność tekstu, przeł.
