description: We revisit the operator mixing in massless QCD-like theories. In particular, we address the problem of determining under which conditions a renormalization scheme exists where the renormalized mixing matrix in the coordinate representation, $Z(x, μ)$, is diagonalizable to all perturbative orders. As a key step, we provide a differential-geometric interpretation of renormalization that allows us to apply the Poincaré-Dulac theorem to the problem above: We interpret a change of renormalization scheme as a (formal) holomorphic gauge transformation, $-\frac{γ(g)}{β(g)}$ as a (formal) meromorphic connection with a Fuchsian singularity at $g=0$, and $Z(x,μ)$ as a Wilson line, with $γ(g)=γ_0 g^2 + \cdots$ the matrix of the anomalous dimensions and $β(g)=-β_0 g^3 +\cdots$ the beta function. As a consequence of the Poincaré-Dulac theorem, if the eigenvalues $λ_1, λ_2, \cdots $ of the matrix $\frac{γ_0}{β_0}$, in nonincreasing order $λ_1 \geq λ_2 \geq \cdots$, satisfy the nonresonant condition $λ_i -λ_j -2k \neq 0$ for $i\leq j$ and $k$ a positive integer, then a renormalization scheme exists where $-\frac{γ(g)}{β(g)} = \frac{γ_0}{β_0} \frac{1}{g}$ is one-loop exact to all perturbative orders. If in addition $\frac{γ_0}{β_0}$ is diagonalizable, $Z(x, μ)$ is diagonalizable as well, and the mixing reduces essentially to the multiplicatively renormalizable case. We also classify the remaining cases of operator mixing by the Poincaré-Dulac theorem.

Shelf-life prediction and flavour quality assessment of pasteurized milk by multivariate analysis of dynamic headspace gas chromatographic data
Creators: name: Vallejo Cordoba, Belinda
Publisher: name: University of British Columbia
Year: 2008

description: An objective analytical system for shelf-life prediction and flavour quality monitoring of pasteurized milk was established. Dynamic headspace capillary gas chromatography (DH-GC) was optimized to achieve adequate resolution and maximum recovery of volatiles isolated from milk. The simultaneous factor optimization approach used for establishing purge and trap conditions during milk volatile isolation resulted in a method of high sensitivity and reproducibility. Volatiles, psychrotrophic bacterial counts and sensory evaluation were monitored during refrigerated storage of pasteurized milk and multivariate statistics were applied to accumulated data. Multivariate statistical analysis, including principal components regression and linear discriminant analysis was applied to 46 peak areas from 134 chromatograms. Principal components regression of gas chromatographic data and flavour related shelf-life was successful in developing a model for milk shelf-life prediction. The resulting standard error of the estimate of less than two days in shelf-life was an excellent approximation for shelf-life prediction purposes. Linear discriminant analysis was able to classify milk into good, marginal and poor quality or into fruity, rancid and normal flavour groups at a greater than 80% success rate (p<.001) In addition, the zone of “good” or “normal” flavour groups could be visualized in two dimensional canonical plots. Thus any sample deviating from this zone could be considered a defective product. Since any test for keeping quality of milk must emphasize those organisms (initially present in low numbers) that can spoil the product under refrigeration, preliminary incubation before volatile detection was included. Using DH-GC for shelf-life prediction and flavour quality assessment of pasteurized milk, results were available in 20 h (18h preliminary incubation + 2h detection and data processing). Although other rapid instrumental techniques have been proposed for milk shelf-life prediction, dynamic headspace gas chromatography coupled to mass spectrometry (DH-GC-MS) as reported in this thesis is the only method that allows the chemical identification of milk volatiles, which are ultimately the cause of off-flavours and termination of shelf-life. Linear discriminant analysis of gas chromatographic data allowed the identification of milk volatiles that contributed most significantly (p<0.01) to the discrimination among flavour quality groups. The analytical system established in this thesis may prove to be a useful quality control tool for the dairy industry.

description: A new and rather independent research field is now emerging on intermodalism, because intermodalism, that is the intermodal transportation, must study the behavior of systems different from single-mode transport systems. In fact, the importance of this new research field, its potential interdisciplinary of modeling the problem with the science of complex networks, are not yet completely appreciated by the scientific community. This is due to several reasons, among others the lack of a common background and a rather cumbersome approach of operation research to the modeling of transportation. In this paper we review the concept of intermodalism and the approach to intermodalism in the operation research field. Then we discuss the intermodal networks in the framework of real world networks to understand the behavior of intermodal systems as a whole.

Institutional Work of Regional Language Movements: Options for Intervention at the Regional Level Taken Brittany as an Example
Creators: name: Lesk, Susanne
Publisher: name: JournaLIPP
Year: 2014

description: According to the UNESCO Atlas of the World’s Languages in Danger, the Breton language is severely endangered. While there were over 1 million Breton speakers around 1950, only 194,500 remained in 2007. The annual decrease in Breton speakers by 8,300 cannot be compensated at present, leading to the crossing of the threshold of 100,000 Breton speakers in about a quarter of a century. The constitutional amendment in 2008, according, for the first time, an official status to regional languages in France, did not provide any real benefits either, except for a higher legitimacy for regional politicians and other actors of regional language movements to implement languagesensitive promotional measures. In this regard, the region of Brittany is a pioneer, as it has demonstrated a high commitment to the promotion of the Breton language since the mid-nineties. In this context, this paper investigates what possibilities exist for locallevel authorities and other strategic actors in the field to encourage the social use of a regional language in all domains of life. First, the sociolinguistic situation in Brittany is outlined and evaluated using secondary data. Second, a qualitative study (in-depth interviews) was conducted to provide further insights into the interdependencies between the different actors in the field of the Breton language policy, and revealed options for policy instrument development by regional governments. Institutional theory is used as a theoretical framework in order to assess distinct practices and instruments for promoting a regional language. Existing and frequently claimed measures are assigned to different forms of institutional work (e.g. mobilisation of support, imitation of best practices); they are performed by the stakeholders in the field and are aimed at boosting the social use of a language. From this institutional perspective, we observe intensive efforts by single persons, organisations and communities (institutional work) and solutions (institutions or socially accepted practices) for introducing institutional change. There is still additional and unused room to manoeuvre at the regional level and a lack of planning for operational implementation. The analysis shows that three forms of institutional work should be further developed in particular, namely: mimicry, theorising and educating. Educating is especially important as it translates into a demand for obligatory bilingual education in order to stabilise the number of speakers. Nonetheless, the motivation of the Breton population, when establishing a language policy for Brittany, should not be overlooked. This means that both top-down and bottom-up perspectives should be pursued at the same time.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We present a general theory of liquid crystals under inhomogeneous electric field in a Ginzburg-Landau scheme. The molecular orientation can be deformed by electric field when the dielectric tensor is orientation-dependent. We then investigate the influence of a charged particle on the orientation order in a nematic state. The director is aligned either along or perpendicular to the local electric field around the charge, depending on the sign of the dielectric anisotropy. The deformation becomes stronger with increasing the ratio $Ze/R$, where $Ze$ is the charge and $R$ is the radius of the particle. Numerical analysis shows the presence of defects around the particle for large $Ze/R$. They are nanometer-scale defects for microscopic ions. If the dielectric anisotropy is positive, a Saturn ring defect appears. If it is negative, a pair of point defects appear apart from the particle surface, each being connected to the surface by a disclination line segment.

Ο κύριος στόχος είναι η παρουσίαση των διαφορετικών ερμηνευτικών προσεγγίσεων σε έργα που εμφανίζονται τόσο στην Ευρώπη όσο και στην Αμερική από τις αρχές του εικοστού αιώνα μέχρι και το 1970. Ξεκινώντας από την λεξιλογική ετυμολογία και τους ορισμούς του Φρόιντ και του Μπατάιγ που υποστηρίζουν την παρουσία τους μέσα στον άνθρωπο συνεχίζουμε στην σύντομη και επιλεκτική αναφορά της επιρροής και της πορείας τους στην Ευρωπαϊκή κοινωνία. Με κοινό χαρακτηριστικό την σύζευξη των δύο καταστάσεων στα τέσσερα κεφάλαια αναπτύσσονται θέματα όπως ο κύκλος της ζωής, οι ερωτικοί δεσμοί, ο φόβος για την γυναικεία σεξουαλικότητα αλλά το ανθρώπινο σώμα. Μέσα από αυτά οδηγούμαστε όχι μόνο σε μία καλλιτεχνική μετάβαση με την μία έννοια να επικρατεί έναντι της άλλης αλλά καταλήγουμε σε έναν γενικότερο προβληματισμό για την θέση και τον ρόλο του θανάτου και του ερωτισμού στον τελευταίο αιώνα πριν την νέα χιλιετία
description: This diploma thesis deals with the simultaneous coexistence of the concepts of death and eroticism. The main aim is to present the different hermeneutic approaches of artworks appearing both in Europe and in America from the early twentieth century until the 1970s. Starting from the lexical etymology and definitions of Freud and Bataille who support death’s and eroticism’s presence within the human being, we continue to a briefly and selectively citation of their influence and their progress in European society. Having in common the combination of the two cases, in the four chapters are developing issues such as the circle of life, the erotic relationships, the fear of female sexuality and the human body. Through these, we are coming to a conclusion that is not only the artistic transition where the one interpretation prevails over the other but we are ending up to a more general reflection of the position and the role of death and eroticism in the last century before the new millennium
“AVREI QUALCOSA DA DIRE”. UN PROGETTO DI SCRITTURA CREATIVA IN   CARCERE
Creators: name: Ottaviano, Giulia
Publisher: name: Italiano LinguaDue
Year: 2015

description: Questo lavoro nasce da un’esperienza di tirocinio all’interno della scuola media interna alla Casa Circondariale Lorusso e Cutugno di Torino. Nella prima parte si evidenziano l’importanza della scuola carceraria negli istituti penitenziari italiani e il fondamentale aiuto che essa può fornire, in particolare, ai detenuti stranieri. Viene poi descritta la struttura del penitenziario e il tipo di formazione offerto ai detenuti italiano e stranieri. Si è dedicata particolare attenzione alle problematiche di una scuola inserita in un contesto di reclusione, dove le limitazioni imposte dall’istituzione influenzano radicalmente non solo l’utenza scolastica ma lo stesso svolgimento delle attività formative. Infine, dopo aver sottolineato l’importanza della scrittura in carcere – strumento di comunicazione ma soprattutto spazio di libertà e libera azione – si propone un progetto didattico di scrittura creativa per detenuti stranieri e italiani che valorizzi l’integrazione tra reclusi provenienti da diverse zone del mondo e la loro cultura e lingua d’origine. Si vuole inserire tale intervento in un’ottica di rieducazione del detenuto, incoraggiandone le inclinazioni personali, favorendo l’acquisizione di fiducia nelle proprie capacità e stima di sé e dunque stimolando la motivazione personale all’apprendimento. Nondimeno si vuole rispondere ai bisogni comunicativi dei detenuti stranieri e non di diverso livello di competenza della lingua italiana.

“I have something to say.” Creative writing in prison

This work stems from the author’s internship experience during Middle school at the Lorusso e Cutugno Prison in Turin. In the first part the importance of school in Italian prisons and the fundamental help they can provide, especially to foreign detainees, is highlighted. The structure of the prison system and the type of training offered to Italian and foreign prisoners is described. Particular attention is paid to the problems a school within a prison faces, where the limitations imposed by the institution radically affect not only the students but the conducting of educational activities. Finally, after stressing the importance of writing in prison – both as a communication tool but especially as a space for freedom of thought and action – an educational project on creative writing for foreign and Italian prisoners that enhances integration between inmates from different parts of the world and native cultures and languages is presented. This experience is part of the process of prisoner re-education, to encourage their personal inclinations, favor the acquisition of self-confidence and self-esteem and thus stimulate the motivation to learn. No less important are the communication needs of foreign and Italian prisoners with different levels of competence in the Italian language.

description: In recent years, researchers have proposed many deep learning (DL) methods for various tasks, and particularly face recognition (FR) made an enormous leap using these techniques. Deep FR systems benefit from the hierarchical architecture of the DL methods to learn discriminative face representation. Therefore, DL techniques significantly improve state-of-the-art performance on FR systems and encourage diverse and efficient real-world applications. In this paper, we present a comprehensive analysis of various FR systems that leverage the different types of DL techniques, and for the study, we summarize 168 recent contributions from this area. We discuss the papers related to different algorithms, architectures, loss functions, activation functions, datasets, challenges, improvement ideas, current and future trends of DL-based FR systems. We provide a detailed discussion of various DL methods to understand the current state-of-the-art, and then we discuss various activation and loss functions for the methods. Additionally, we summarize different datasets used widely for FR tasks and discuss challenges related to illumination, expression, pose variations, and occlusion. Finally, we discuss improvement ideas, current and future trends of FR tasks.

description: The research project ELDIA (European Language Diversity for All), funded by the 7th Framework Programme of the European Union from March 2010 till September 2013, set out to examine the state of multilingualism in today’s Europe. The project, working on a sample of Finno-Ugric minorities from the Barents Sea to Slovenia, began with a context analysis (desk research) and proceeded through fieldwork-based case studies (questionnaire surveys and interviews) as well as interconnected media-sociological and law analyses. One of the main results was the EuLaViBar (European Language Vitality Barometer), a tool for assessing the state of language maintenance and identifying the points where special support measures are needed. In this paper, some central results of the project, with respect to maintaining language diversity in Europe, are discussed.

German Sign Language (DGS) as an instance of an endangered language?
Creators: name: Wrobel, Ulrike
Publisher: name: JournaLIPP
Year: 2014

description: The aim of this article is to call attention to the fact that the existence of sign languages like German Sign Language is in danger. I would like to point out the factors that led to this development and to outline its extent. Firstly, I will give a very short introduction to sign language. In (2.), I will present the factors that led to the endangerment of sign languages: there are prejudices against the speakers (paternalism und discrimination, also with respect to public life), and reaction to this is personal withdrawal and social dissociation. In addition, there is a medicalisation of the speakers, a bias concerning the concurrent acquisition of a spoken and a signed language, a degradation of the language itself and deficiency of institutional support of the language as well as a lack of knowledge about the culture and its products. In (3.) I will try to evaluate these factors by referring to the sociolinguistic concept of vitality (see Giles, Bourhis/Taylor 1977) and will conclude with a calculation of the danger that German Sign Language will cease to exist in the future. It will be demonstrated that German Sign Language is an atypical example for an endangered language. The main reason for this estimation is the fact that there are also many young speakers, as well as the observation that all of the speakers are strongly trying to maintain their language and use it as often as they can. However, the analysis of DGS allows considering some recommendations for the preservation of languages in general.

description: We investigate the unpolarized virtual photon structure functions $F_2^gamma(x,Q^2,P^2)$ and $F_L^gamma(x,Q^2,P^2)$ in perturbative QCD for the kinematical region $Lambda^2 ll P^2 ll Q^2$, where $-Q^2(-P^2)$ is the mass squared of the probe (target) photon and $Lambda$ is the QCD scale parameter. Using the framework of the operator product expansion supplemented by the renormalization group method, we derive the definite predictions for the moments of $F_2^gamma(x,Q^2,P^2)$ up to the next-to-next-to-leading order (NNLO) (the order $alphaalpha_s$) and for the moments of $F_L^gamma(x,Q^2,P^2)$ up to the next-to-leading order (NLO) (the order $alphaalpha_s$). The NNLO corrections to the sum rule of $F_2^gamma(x,Q^2,P^2)$ are negative and found to be $7% sim10%$ of the sum of the LO and NLO contributions, when $P^2=1 {rm GeV}^2$ and $Q^2=30sim 100 {rm GeV}^2$ or $P^2=3 {rm GeV}^2$ and $Q^2=100 {rm GeV}^2$, and the number of active quark flavors $n_f$ is three or four. The NLO corrections to $F_L^gamma$ are also negative. The moments are inverted numerically to obtain the predictions for $F_2^gamma(x,Q^2,P^2)$ and $F_L^gamma(x,Q^2,P^2)$ as functions of $x$.

description: The networked opinion diffusion in online social networks (OSN) is often governed by the two genres of opinions - endogenous opinions that are driven by the influence of social contacts among users, and exogenous opinions which are formed by external effects like news, feeds etc. Accurate demarcation of endogenous and exogenous messages offers an important cue to opinion modeling, thereby enhancing its predictive performance. In this paper, we design a suite of unsupervised classification methods based on experimental design approaches, in which, we aim to select the subsets of events which minimize different measures of mean estimation error. In more detail, we first show that these subset selection tasks are NP-Hard. Then we show that the associated objective functions are weakly submodular, which allows us to cast efficient approximation algorithms with guarantees. Finally, we validate the efficacy of our proposal on various real-world datasets crawled from Twitter as well as diverse synthetic datasets. Our experiments range from validating prediction performance on unsanitized and sanitized events to checking the effect of selecting optimal subsets of various sizes. Through various experiments, we have found that our method offers a significant improvement in accuracy in terms of opinion forecasting, against several competitors.

Dabei werden zunächst allgemeine Charakteristika einer Reliktvarietät vorgestellt und daran anschließend Reduktionsprozesse des deutschen Kasussystems bei 20 Sprechern dieser Varietät analysiert. Die Ergebnisse untermauern die Annahme, dass morphologische Strukturen nur in den Konstruktionen erhalten bleiben, die entweder im frühen Erwerbsprozess sehr stark verwurzelt waren (im Sinne von entrenched constructions) oder sehr häufig gebraucht wurden. Darüber hinaus zeigt sich, dass morphologische Markierungen besser bewahrt werden, wenn das schriftsprachliche System einer Sprache ebenfalls erworben wurde.

William Makepeace Thackeray’s Catherine : a story : a critical edition with commentaries
Creators: name: Goldfarb, Sheldon F.
Publisher: name: University of British Columbia
Year: 2008

description: This dissertation consists of a critically edited text of William Makepeace Thackeray's first novel, Catherine, along with a complete set of annotations, an extensive textual apparatus, appendices reprinting the sources for the real-life murder story on which Thackeray based his novel, and commentaries discussing the politics of the novel, the textual history and textual difficulties of the novel, and the novel's literary and historical context. In the absence of the manuscript, the copy-text for this edition is the first edition from Eraser's Magazine in 1839-40, the only edition from Thackeray's lifetime. Following this copy-text, the present edition includes all the passages expurgated in posthumous editions, expurgations recorded in one section of the Textual Apparatus. Another section of the apparatus consists of a glossary of Thackeray's characteristic spellings and capitalizations, based on a study of his surviving manuscripts. This study suggests that the style of accidentals in the first edition is not Thackerayan. However, because of the difficulty of restoring Thackerayan accidentals, the first edition accidentals have in general been left untouched, with the only emendations in this edition (all of which are recorded in the apparatus) being those made to correct errors in the copy-text. The annotations to the edition, besides explaining obscurities in the text, indicate the command Thackeray had over his historical materials, reveal his borrowings from earlier authors, and point out motifs that recur in other works by him. The political commentary to the edition discusses Thackeray's adoption of the Tory politics of Eraser's in his novel even though his views at the time were Radical. The critical commentary discusses the alterations Thackeray made to his sources for the murder story and points out that although the novel originated as an attack on the Newgate school of fiction and the glorification of criminals, it in fact, for the most part, celebrates the rogues it depicts. The general introduction notes that despite the resulting inconsistency in the novel, Catherine contains many qualities - including narrative virtuosity, satirical cleverness, and a skilful presentation of picaresque adventures - which suggest that it should no longer be neglected

description: CMInject simulates nanoparticle injection experiments of particles with diameters in the micrometer to nanometer-regime, e.g., for single-particle-imaging experiments. Particle-particle interactions and particle-induced changes in the surrounding fields are disregarded, due to low nanoparticle concentration in these experiments. CMInject's focus lies on the correct modeling of different forces on such particles, such as fluid-dynamics or light-induced interactions, to allow for simulations that further the scientific development of nanoparticle injection pipelines. To provide a usable basis for this framework and allow for a variety of experiments to be simulated, we implemented first specific force models: fluid drag forces, Brownian motion, and photophoretic forces. For verification, we benchmarked a drag-force-based simulation against a nanoparticle focusing experiment. We envision its use and further development by experimentalists, theorists, and software developers.

Miyako-Ryukyuan and its contribution to linguistic diversity
Creators: name: Jarosz, Aleksandra
Publisher: name: JournaLIPP
Year: 2014

description: The paper provides introductory information on Miyako-Ryukyuan (Miyakoan). Miyakoan belongs to the Sakishima branch of the Japonic language family, the concept of which counterbalances the until-recently prevalent notion that Japan should be a linguistically homogenous country, and Japanese a language isolate with many unintelligible “dialects”. Following the statement that the endangered Miyako-Ryukyuan language is in an urgent need of extensive documentation and in-depth description, as well as producing more works in English devoted to it, the author introduces a few topics that may be of interest to Japanese/ Japonic linguists and language typologists alike: the “apical” vowel, syllabic consonants, focus marking strategies and formal modality markers. Each topic has been exemplified by Miyako-Ryukyuan samples from Nikolay Nevskiy’s Taishō-era handwritten fieldnotes, as retrieved and analyzed by this author.

description: Database fingerprinting have been widely adopted to prevent unauthorized sharing of data and identify the source of data leakages. Although existing schemes are robust against common attacks, like random bit flipping and subset attack, their robustness degrades significantly if attackers utilize the inherent correlations among database entries. In this paper, we first demonstrate the vulnerability of existing database fingerprinting schemes by identifying different correlation attacks: column-wise correlation attack, row-wise correlation attack, and the integration of them. To provide robust fingerprinting against the identified correlation attacks, we then develop mitigation techniques, which can work as post-processing steps for any off-the-shelf database fingerprinting schemes. The proposed mitigation techniques also preserve the utility of the fingerprinted database considering different utility metrics. We empirically investigate the impact of the identified correlation attacks and the performance of mitigation techniques using real-world relational databases. Our results show (i) high success rates of the identified correlation attacks against existing fingerprinting schemes (e.g., the integrated correlation attack can distort 64.8\% fingerprint bits by just modifying 14.2\% entries in a fingerprinted database), and (ii) high robustness of the proposed mitigation techniques (e.g., with the mitigation techniques, the integrated correlation attack can only distort $3\%$ fingerprint bits).

description: The current-voltage ($IV$) characteristics beyond the linear response regime of magnetic tunnel junction (MTJ) is systematically investigated. We find a clear negative correlation between the two coefficients to characterize the linear ($I$$\propto$$V$) and the lowest-order nonlinear ($I$$\propto$$V^3$) currents, which holds regardless of the temperature and the thickness of the tunnel barrier. This observation cannot simply be explained by the standard tunneling model such as the Brinkman model, suggesting a mechanism intrinsic to MTJ. We propose a phenomenological model based on the Julliére model that attributes the observed negative correlation to the spin-flip tunneling assisted by a magnon. These results suggest a fundamental law between the linear and the nonlinear response of MTJ.

description: We construct the 11D supermembrane with topological central charges induced through an irreducible winding on a G2 manifold realized from the T7/Z2xZ2xZ2 orbifold construction. The hamiltonian H of the theory on a T7 target has a discrete spectrum. Within the discrete symmetries of H associated to large diffeomorphisms, the Z2xZ2xZ2 group of automorphisms of the quaternionic subspaces preserving the octonionic structure is relevant. By performing the corresponding identification on the target space, the supermembrane may be formulated on a G2 manifold, preserving the discretness of its supersymmetric spectrum. The corresponding 4D low energy effective field theory has N=1 supersymmetry.

Language documentation in the 21st century
Creators: name: Austin, Peter K.
Publisher: name: JournaLIPP
Year: 2014

description: Language documentation emerged as a new sub-field of linguistics in 1995 and has developed and expanded over the past 20 years. In this paper we outline the defining characteristics of language documentation as presented in the late 1990s and discuss some of the changes in the field that have occurred since. These include a move away from concern for best practices, standards and tools to a more critical and reflexive approach that highlights diversity and flexibility of individual documentation projects in their social, cultural and political contexts, as well as the need for greater attention to goals and outcomes. There have also been developments in archiving that build upon social networking models linking people to each other, rather than seeing documentation as being primarily about ‘data’ and ‘resources’.

description: Cosmological models predict that galaxies forming in the early Universe experience a chaotic phase of gas accretion and star formation, followed by gas ejection due to feedback processes. Galaxy bulges may assemble later via mergers or internal evolution. Here we present submillimeter observations (with spatial resolution of 700 parsecs) of ALESS 073.1, a starburst galaxy at redshift z~5, when the Universe was 1.2 billion years old. This galaxy's cold gas forms a regularly rotating disk with negligible noncircular motions. The galaxy rotation curve requires the presence of a central bulge in addition to a star-forming disk. We conclude that massive bulges and regularly rotating disks can form more rapidly in the early Universe than predicted by models of galaxy formation.

Forum on Jerrold Levinson, "Contemplating Art"
Creators: name: Rotili, With J. Levinson
Publisher: name: Lebenswelt. Aesthetics and philosophy of experience.
Year: 2014

description: Jerrold Levinson’s Contemplating Art provides the readers with a variety of heterogeneous topics and issues. The discussants who took part in the Forum about Levinson’s book chose four different “tracks” dealt with, offering four different reflections. The main topics of the debate are: music, historicity, aesthetic properties and aesthetic contextualism.

Starting on the fact that music is one of the main fields of Contamplating Art Alessandro Bertinetto focus his paper on the ‘musical’ chapters of the book that 1) defend the theory of musical expressivity presented by Levinson in his previous books (the ‘theory of musical persona’); 2. articulate it in reference to particular aspects of musical experience, and 3. examine its contribution for the understanding of the narrative and dramatic dimension of music as well as 4., in general, for its artistic value.

Michele Di Monte’s aim is to focus on the questions raised by the alleged essential historicality of the concept of art and the formal definition of the concept itself. He discusses, in particular, the epistemic basis and status of what Levinson calls ‘our present concept of art’, the logical outcomes of its role in defining and identifying the art of the past and the problematic relationship between a universality requirement and the theory’s pretension to historicality.

Filippo Focosi discusses in the first place the passages of Levinson’s book where his paradigmatic aesthetic principle explicitly occurs; secondly, he shows how such a principle, as is there articulated, can disclose interest perspectives on other aspects of Levinson’s theories about art and aesthetic properties.

The paper by Lisa Giombini focuses on on the role of context in Levinson’s definition of art.Afterdefining Levinson’s version of aesthetic contextualism, Giombiniunderlines how Levinson’s intentional-historical definition may provide fertile ground for a peculiar form of contextualism where the relevant context is constituted by the history of art and the practice of art alone. Finally she inquires whether Levinson’s identifying works of art with wholly relational intentionally-historically defined concepts may interfere with his adhesion to aesthetic realism.

Computer-assisted estimates for Birkhoff normal forms

description: Birkhoff normal forms are commonly used in order to ensure the so called "effective stability" in the neighborhood of elliptic equilibrium points for Hamiltonian systems. From a theoretical point of view, this means that the eventual diffusion can be bounded for time intervals that are exponentially large with respect to the inverse of the distance of the initial conditions from such equilibrium points. Here, we focus on an approach that is suitable for practical applications: we extend a rather classical scheme of estimates for both the Birkhoff normal forms to any finite order and their remainders. This is made for providing explicit lower bounds of the stability time (that are valid for initial conditions in a fixed open ball), by using a fully rigorous computer-assisted procedure. We apply our approach in two simple contexts that are widely studied in Celestial Mechanics: the Hénon-Heiles model and the Circular Planar Restricted Three-Body Problem. In the latter case, we adapt our scheme of estimates for covering also the case of resonant Birkhoff normal forms and, in some concrete models about the motion of the Trojan asteroids, we show that it can be more advantageous with respect to the usual non-resonant ones.

description: We propose a new source for the cosmological density perturbation which is passive fluctuations of the inflaton driven dynamically by a colored quantum noise as a result of its coupling to other massive quantum fields. The created fluctuations grow with time during inflation before horizon-crossing. However, the larger-scale modes cross out the horizon earlier, thus resulting in a suppression of their density perturbation as compared with those on small scales. By using current observed CMB data to constrain the parameters introudced, we find that a significant contribution from the noise-driven perturbation to the density perturbation is still allowed. It in turn gives rise to a suppression of the large-scale CMB anisotropy that may be relevant to the observed low quadrupole in the WMAP CMB anisotropy data. We also briefly discuss the implications to the energy scale of inflation and the spectral index and non-Gaussianity of the density perturbation.

description: Quantum Key Distribution (QKD) allows unconditionally secure communication based on the laws of quantum mechanics rather then assumptions about computational hardness. Optimizing the operation parameters of a given QKD implementation is indispensable in order to achieve high secure key rates. So far, there exists no model that accurately describes entanglement-based QKD with continuous-wave pump lasers. For the first time, we analyze the underlying mechanisms for QKD with temporally uniform pair-creation probabilities and develop a simple but accurate model to calculate optimal trade-offs for maximal secure key rates. In particular, we find an optimization strategy of the source brightness for given losses and detection-time resolution. All experimental parameters utilized by the model can be inferred directly in standard QKD implementations, and no additional assessment of device performance is required. Comparison with experimental data shows the validity of our model. Our results yield a tool to determine optimal operation parameters for already existing QKD systems, to plan a full QKD implementation from scratch, and to determine fundamental key rate and distance limits of given connections.

description: The purpose of this survey is to explain an approach to the Atiyah-Floer conjecture via a new instanton Floer homology with Lagrangian boundary conditions. This is a joint project with Dietmar Salamon. This paper also provides a rough guide to the analysis of anti-self-dual instantons with Lagrangian boundary conditions (in earlier papers), which is the crucial ingredient of our approach.

Bairisch nach Maß?
Creators: name: Eibl, Melanie
Publisher: name: JournaLIPP
Year: 2014

description: Im Jahr 2009 wurde das Bairische durch den UNESCO Atlas of the World´s Languages in Danger als „vulnerable“ und somit „potenziell gefährdet“ eingestuft. Interessant an dieser Einordnung ist neben der öffentlichen Debatte um eine etwaige Bedrohung des Dialekts auch die UNESCO-Darstellung des Bairischen als Sprache, da es in der Linguistik gemeinhin als größter deutscher Dialektverband angesehen wird. Diese Klassifizierung bedient die Debatte um Dialekt und Standard erneut. In diesem Beitrag soll nach einer Diskussion über Sprache und Dialekt und der entsprechenden Einordnung des Bairischen der Frage nachgegangen werden, ob es in Bayern staatliche Sprachplanung bereits gibt oder ob es solcher insgesamt gesehen bedarf. Dabei werden staatliche wie auch von anderen Institutionen angeregte sprachpflegerische und -planerische Bemühungen und Regelungen erörtert. Ziel ist es, sich angesichts der „besonderen“ Situation des Bairischen und der in Bayern vorkommenden Varietäten mit Sinn und Wichtigkeit sprachregulierender Maßnahmen auseinanderzusetzen.
