description: We perform molecular dynamics simulations of liquid water at different temperatures and calculate the water viscosity, the translational and rotational water diffusivities in the laboratory frame as well as in the comoving molecular frame. Instead of interpreting the results as deviations from the Stokes-Einstein and Stokes-Einstein-Debye relations, we describe the translational and rotational diffusivities of water molecules by three models of increasing complexity that take the structural anisotropy of water into account on different levels. We first compare simulation results to analytical predictions for a no-slip sphere and a no-slip ellipsoid. We show that the no-slip sphere can approximate laboratory-frame isotropic translational and rotational diffusivities but fails to describe the anisotropic molecular-frame diffusivities. The no-slip ellipsoid can describe the translational anisotropic molecular-frame diffusivities exactly but fails to describe the translational and rotational anisotropic molecular-frame diffusivities simultaneously. Since an ellipsoidal model with slip boundary conditions is not analytically tractable, we define a heuristic spherical model with tensorial slip lengths and tensorial hydrodynamic radii. We show that this model simultaneously describes the laboratory-frame isotropic translational and rotational diffusivities, as well as, in a restricted viscosity range, the anisotropic molecular-frame diffusivities.
title: Di che cosa parliamo quando parliamo di diritti: uguaglianza, differenze, queer
Creators: name: Dell'Aversano, Carmen
Publisher: name: Università di Pisa
Year: 2019

description: This paper presents a critique of the Enlightenment concept of rights. Based as it is on equality, it deploys the term in both a descriptive and a prescriptive way, acting as a device to exact the performance of normalcy, and to deprive anyone who proves either unwilling or unable to comply of the “right to have rights”. A queer analysis of equality shows it to be constructed collusively, through the socially shared decision not to notice a number of traits, and to concentrate instead on what two or more objects have in common despite their inevitable differences. To opt out of this collusion means to embark on a radical critique of equality as the foundation of a philosophy of law, and to replace it with a nuanced and respectful consideration of the different and incommensurable needs and vulnerabilities of all sentient beings.

description: The degradation of proton exchange membrane water electrolysis cells is usually measured in a temporal increase of the cell voltage. Although this is sufficient to evaluate the stability of a system, it is less suitable for targeted material development. Thus, an overpotential-specific and temporally resolved electrochemical characterization protocol is proposed. In this the ohmic overpotential is determined with high frequency resistance measurements. These are also used in combination with polarization curves to distinguish between the kinetic and mass transport overpotentials and to determine kinetic key parameters, according to the Butler-Volmer and transition state theory. Complementary electrochemical impedance spectroscopy measurements further unravel the individual resistances. On this basis, the following statements can already be issued. The major share of the measured cell voltage increase, i.e. degradation, is of apparent nature as it is recovered once lower potentials are applied. It is suggested that this is due to changes in the oxidation states of the iridium-based catalyst. Real degradation occurs in the ohmic and mass transport overpotential mainly at higher current densities and longer operating times. The increasing kinetic overpotential with increasing operating time is primarily potential-driven. Interestingly, both the Tafel slope and the apparent exchange current density slightly increase over time. © 2019 The Author(s). Published by ECS.
The decolonial project of Alfredo Jaar
Creators: name: San Martin, Florencia
Publisher: name: No Publisher Supplied
Year: 2019

description: This dissertation reframes the art of Alfredo Jaar (b. Santiago, Chile, 1956; New York-based since 1982) through the lens of decolonial thought. Decoloniality is a post-continental philosophical system that regards colonialism as a fundamental element in the formation of the modern capitalist world system which began with European expansion in the Americas in the 16th century. A way of doing, thinking, and being, decoloniality posits that decolonization is an incomplete but urgent, necessary, and ethical imperative. I argue that Jaar’s art overall is itself a decolonial project whose aim is to identify and to challenge the inherently hierarchical relationships of our modern capitalist world system. Relying on archival research, personal interviews, and a transdisciplinary approach to contemporary art history, I propose that at the core of Jaar’s practice is a decolonial critique of the catastrophic humanitarian and epistemological consequences of neoliberalism, a capitalist economic project and ideological outlook that defines our present moment. This was particularly significant during the Chilean civic-military dictatorship (1973-1990) when Jaar was coming of age as an artist. While this dissertation examines main themes and concerns in Jaar’s art since his earliest series of works in 1974 to the present, it centers particularly in his work made in the early 1980s New York, since it was in this specific time and space that Jaar developed the main lines of inquiry of his practice. In examining Jaar’s critique of the enmeshed relationship between neoliberalism and coloniality, this dissertation also unearths an important hemispheric, anti-imperialist, and solidarity genealogy around Latin America whose epicenter was New York in the 1970s and 1980s. In an era where right-wing dictatorships have yielded to failed socialist states in Latin America, this dissertation provides a fresh and timely understanding of both Jaar’s art and the contemporary situation of the Americas. It is relevant for furthering the understanding of Latin American and American art as hemispheric and transdisciplinary fields, critiquing the discourse on globalization and global contemporary art, considering the relationship between art and politics and art and ethics, and contributing to the field of memory studies in Latin America.
title: Self-adaptive application for indoor wayfinding for individuals with cognitive impairments

Publisher: name: Technological University of Dublin
Year: 2018

description: This article focuses on describing a Model Driven Archi- tecture (COCA-MDA) approach that facilitates the develop- ment of self-adaptive application for indoor wayfinding for individuals with cognitive impairments. COCA-MDA pro- vides the following benefits: 1) It enables the architecture to anticipate several behavioural variations based on the context and the specific needs of the individuals with cog- nitive impairments. 2) It enables the application to proac- tively anticipate or reactively address unforeseen changes through support by a dynamic-decision making and policy framework. The policy framework is based on a stable de- scription of software models and proprieties. 3) It can de- compose the application into several architectural units to allow developers to decide which part of the architecture should be notified when a specific context condition occurs.

The broken symmetry associated with these Goldstone bosons is further speculated to be the conservation of the particles of dark matter.

Vibroacoustics of the piano soundboard: (Non)linearity and modal properties in the low and mid-frequency ranges

description: The piano soundboard transforms the string vibration into sound and therefore, its vibrations are of primary importance for the sound characteristics of the instrument. An original vibro-acoustical method is presented to isolate the soundboard nonlinearity from that of the exciting device (here: a loudspeaker) and to measure it. The nonlinear part of the soundboard response to an external excitation is quantitatively estimated for the first time, at \approx -40 dB below the linear part at the ff nuance. Given this essentially linear response, a modal identification is performed up to 3 kHz by means of a novel high resolution modal analysis technique (Ege et al., High-resolution modal analysis, JSV, 325(4-5), 2009). Modal dampings (which, so far, were unknown for the piano in this frequency range) are determined in the midfrequency domain where FFT-based methods fail to evaluate them with an acceptable precision. They turn out to be close to those imposed by wood. A finite-element modelling of the soundboard is also presented. The low-order modal shapes and the comparison between the corresponding experimental and numerical modal frequencies suggest that the boundary conditions can be considered as blocked, except at very low frequencies. The frequency-dependency of the modal density and the observation of modal shapes reveal two well-separated regimes. Below \approx 1 kHz, the soundboard vibrates more or less like a homogeneous plate. Above that limit, the structural waves are confined by ribs, as already noticed by several authors, and localised in restricted areas (one or a few inter-rib spaces), presumably due to a slightly irregular spacing of the ribs across the soundboard.
description: Research highlights: - Nonlinearity characterization of a structure independently from its exciting device. - Experimental modal identification, including damping, in the mid-frequency range. - Boundary conditions, low-and high-frequency regimes clarified in the piano soundboard. - Good match between experimental observations and FEM results at low frequencies. - FEM of a non-regularly ribbed soundboard reveals high-frequency localization in piano

description: Using a theoretical model for risky investment decisions, we study the effect of interest deductibility restrictions on the choice of organizational form. We analyze the two most widely used approaches: first, rules that limit the interest deductibility if the firm’s leverage exceeds a specific level, and second, rules that restrict the interest deduction if the interest expenses exceed a specific percentage of the firm’s earnings. Although these restrictions apply uniformly for partnerships and corporations in many countries, we find that they usually distort the choice of organizational form. We demonstrate that only leverage-based interest deductibility restrictions can in theory be modified to achieve organizational form neutrality. However, this requires a legal form dependent application or absence of dividend taxation and in any case a full loss offset which is in contrast to current law in many countries. If one considers corporate loss offset limitations, both types of interest deductibility restrictions always distort the choice of organizational form. Thus, the introduction of interest deductibility restrictions is actually in conflict with the legislators’ often declared aim to design tax systems that are neutral with respect to the choice of organizational form.

description: We survey a new approach to the duality-invariant systems of nonlinear electrodynamics, based on introducing auxiliary bi-spinor fields. In this approach, the entire information about the given self-dual system is encoded in the U(1) invariant interaction of the auxiliary fields, while the standard self-dual Lagrangians appear on shell as a result of eliminating auxiliary fields by their equations of motion. Starting from the simplest U(1) duality, we show how this approach can be generalized to the U(N) duality (with N independent Maxwell field strengths), as well as to self-dual systems of N = 1 supersymmetric electrodynamics. Also, it works perfectly for self-dual systems with higher derivatives in the action.
title: Populism and the impact of technology in persuasive propaganda
Creators: name: Banerjee, Rituparna
Publisher: name: Universität Salzburg
Year: 2019

description: The recent years have exceedingly witnessed an ascent of leaders and movements world-wide that ostensibly reflect a certain ‘populist’ sentiment. In this connection, the world’s transforming political landscape has, in the past two decades, seen populist parties constitute parliaments based on an anti-elite, anti-corruption rhetoric – a new form of what is supposedly democracy. The rush towards energetic authoritarian ‘solutions’, purportedly people-centric, demonstrate wide ranging consequences from war (Russia, Turkey); ethno-religious ‘purification’ (India, Hungary, Myanmar); magnification of presidential powers and the corresponding abandonment of civil rights and rule of law in China, Rwanda, Venezuela, Thailand and the Philippines. These only constitute some of the telling examples. This paper intends to examine the evolution of populism vis-a-vis the ways in which it is increasingly being impacted by digital technology. One way in which I will approach this is through a brief study of the history of populism to explore its specific order or pattern of communication. This can inform ways in which digital technologies are shaping new structures and bringing hitherto absent dimensions to this age-old political/social phenomenon. I am motivated to explore the relationship between network society and political manipulation and investigate, if such a relationship at all exists, whether it is veiled in a garb of ‘populist inclusivity’. This study has three inter-related steps. In the first, I would attempt to formulate a working definition of populism. Secondly, I shall trace the evolution of populist propaganda and investigate if it is underscored historically by a common rhetoric. Finally, I attempt to demonstrate how digital technologies shape popular politics in recent times and impact the nature and content of publics’ discourses, foregrounding a complicated nexus in performing propaganda politics.

description: The purpose of this paper is to discuss the concept of e-democracy in literature, with a focus on the current challenges to its applicability in real voting systems. The discussion starts with a brief overview of relevant definitions by different scholars on the topic of electronic democracy. The main challenges to the applicability of e-democracy are then analysed from three different perspectives: technical challenges, ethical issues and the perception of the value of e-Votes in the modern digital society. The paper ends with the presentation and brief description of different relevant cases of existing e-voting platforms, with a focus on their principal weaknesses and features.

description: The timing properties of radio pulsars provide a unique probe of neutron star interiors. Recent observations have uncovered quasiperiodicities in the timing and pulse properties of some pulsars, a phenomenon that has often been attributed to free precession of the neutron star, with profound implications for the distribution of superfluidity and superconductivity in the star. We advance this program by developing consistency relations between free precession and pulsars glitches, and we show that there are difficulties in reconciling the two phenomena in some precession candidates. This indicates that the precession model used here needs to be modified or some other phenomenon is at work in producing the quasiperiodicities, or even that there is something missing in terms of our understanding of glitches. © 2017 Authors.

description: We examine the impact of sorbitol admixture to the hole-conduction polymer PEDOT:PSS [poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)] on the characteristics of PEDOT:PSS/crystalline silicon heterojunction solar cells. We fabricate solar cells where the PEDOT:PSS layer is deposited as a hole-collecting contact at the cell rear, whereas the electron-collecting front is conventionally processed by means of phosphorus diffusion. Surprisingly, we observe that the admixture of the infrared-transparent sorbitol not only improves the short-circuit density of the solar cells due to the reduction of the infrared parasitic absorption, but also improves the passivation quality of PEDOT:PSS on silicon and hence the open-circuit voltage of the solar cells. The series resistance is not influenced by the admixture of sorbitol up to 4.0 wt.% sorbitol admixture in the PEDOT:PSS dispersion, but shows a pronounced increase for larger sorbitol contents. The optimal sorbitol content concerning efficiency is hence 4.0 wt.%, leading to an energy conversion efficiency of 20.4% at one sun, which is more than 1% absolute higher compared to the efficiency of the reference cells without sorbitol.

description: The objective of the PANACEA ICT-2007.2.2 EU project is to build a platform that automates the stages involved in the acquisition, production, updating and maintenance of the large language resources required by, among others, MT systems. The development of a Corpus Acquisition Component (CAC) for extracting monolingual and bilingual data from the web is one of the most innovative building blocks of PANACEA. The CAC, which is the first stage in the PANACEA pipeline for building Language Resources, adopts an efficient and distributed methodology to crawl for web documents with rich textual content in specific languages and predefined domains. The CAC includes modules that can acquire parallel data from sites with in-domain content available in more than one language. In order to extrinsically evaluate the CAC methodology, we have conducted several experiments that used crawled parallel corpora for the identification and extraction of parallel sentences using sentence alignment. The corpora were then successfully used for domain adaptation of Machine Translation Systems.

These Fermi velocity values and their average were found to decrease with increasing in-plane homogeneous biaxial strain; the variation in Fermi velocity is quadratic in strain. The results, which can be verified by Landau level spectroscopy and quantum capacitance measurements of bi-axially strained graphene, promise potential applications in graphene based straintronics and flexible electronics.

description: Locally aluminum-doped p-type silicon regions are formed by in-line high-rate evaporation of aluminum. We deposit aluminum layers of 28 μm thickness at dynamic deposition rates of 20 μm×m/min on locally laser-ablated Al2O3 / SiNx passivation layers. Due to the high substrate temperature of up to 778°C during deposition an Al-doped p+ region is formed. Using the camera-based dynamic infrared lifetime mapping technique we determine a contact recombination velocity of 1000 ± 100 cm/s for local Al-p+ regions on p-type silicon wafers of 1.5 ωcm resistivity. The recombination velocity between the contacts is determined to 4.4 ± 0.5 cm/s after deposition.
Superfluid, staggered state, and Mott insulator of repulsively interacting three-component fermionic atoms in optical lattices

description: We review our theoretical analysis of repulsively interacting three-component fermionic atoms in optical lattices. We discuss quantum phase transitions at around half filling with a balanced population by focusing on Mott transitions, staggered ordering, and superfluidity. At half filling (with 3/2 atoms per site), characteristic Mott transitions are induced by the anisotropic interactions, where two-particle repulsions between any two of the three colors have different strengths. At half filling, two types of staggered ordered states appear at low temperatures depending on the anisotropy of the interactions. As the temperature increases, phase transitions occur from the staggered ordered states to the unordered Mott states. Deviating from half filling, an exotic superfluid state appears close to a regime in which the Mott transition occurs. We explain the origin of these phase transitions and present the finite-temperature phase diagrams.

description: This article focuses on some of the characters of Euripides' Bacchae using a queer, philologically founded, analisys approach. Our starting hypothesis is that the family relationships between some characters of the tragedy correspond to a symbolic genealogy, that connects some different episodes of ancient Greek mythology, creating a unique, coherent meaning. So, three characters of the tragedy – Actaeon, Pentheus and Dionysus – will be analyzed as different models of masculinity: two of them (Atteone and Penteo) are “loser” men, for different reasons, while Dionysus appears to be a winner, but his model of masculinity is absolutely heretical, eccentric, basically not virile and, in the last instance, queer.

title: Exploring queer spaces in and through the Indian classical dance Bharatanatyam
Creators: name: Azzarelli, Sara
Publisher: name: Università di Pisa
Year: 2019

description: In the Indian classical dance Bharatanatyam, dancers use their body as a means to tell stories. In particular, Abhinaya, the narrative narrative technique featured in this choreutic form, provides performers with codified series of bodily attitudes, hand gestures and facial expressions through which they become any character of their epic and mythological narrations, flowing between age, class and gender differences. From a mainstream perspective, this play of impersonations is largely considered - among dancers and observers - as a mere matter of acting. However, by exploring the peculiar artistic and activist activities of a number LGBTIQ Indian dancers encountered by Sara during her ethnographic research in Tamil Nadu, as well as by reflecting on our own work – which has been partly shared with the Cirque Conference’s Audience who have attended our performance – we aim to recount the marginal perspective of a minority of dancers who find, in – and through -this dance form, multiple spaces of agency, inclusive zones of unstable, changing identities and desires, queer spaces.

description: This article investigates queer vocality as it impacts on contemporary experiences and imaginings of race, gender and sexuality within the South African context. By examining the very applicability of queer (as term and methodology) within the South African context, and paying particular attention to its relationship to voice, this article explores how ideas surrounding race, gender and sexuality bears on South Africa as a sonic environment. The work of South African performing artist Umlilo is specifically drawn upon as the basis of this investigation. As a self-identified queer, black, non-binary artist, Umlilo offers a vocal challenge to patriarchal, racist, hetero- and/or cisnormative conventions, and this article explores how such challenges are brought into effect and into voice.
title: Ambivalence in encounters with my big fat Greek closet
Creators: name: Chairetis, Spyridon
Publisher: name: Università di Pisa

description: Both fat people and queer people diverge from the norms that control who is perceived as societally normal versus abnormal. While literature on the closet has encapsulated the experiences of the two subject positions as distinct entities, limited scholarship examines the relationship between fatness and queerness vis-à-vis the closet. Drawing on fat studies, queer theory, and autoethnography, I critically examine my encounters with the closet both inside and outside of Greece. Reflecting on my experience as a queer fat boy/man who spent a great deal of his teenage and early adult life in Greece and the United Kingdom, I weave together stories and emotions embodied in different spatiotemporal contexts and problematize notions of gender, sexuality, fatness, agency, and Greekness. This article considers how a subject may react to and negotiate the tensions that arise when multiple identity markers intersect, overlap and/or collide. It also revisits the undertheorized concept of ambivalence through a queer lens, in order to propose fresh strategies and ways of inhabiting bodies, identities, and spaces.

description: Ultra-thin silicon wafer have to withstand forces and stresses during handling procedures without breakage. Here we investigate the failure stresses of ?30 ?m thick monocrystalline silicon films produced with the porous silicon process by use of a three line bending setup. We use a finite element simulation in order to evaluate the experiments and conclude that the porous silicon layers break at stresses comparable to those of silicon wafers with standard thickness. The edge preparation has a large impact on the failure stress. For samples with manually cleaved edges the failure stress surpasses 600 MPa, which is the largest stress that is accessible with our testing setup.

description: We demonstrate an up to now unrecognized and very effective mechanism which prevents filament collapse and allows persistent self-guiding propagation retaining a large portion of the optical energy on axis over unexpected long distances. The key ingredient is the possibility of continuously leaking energy into the normal dispersion regime via the emission of resonant radiation. The frequency of the radiation is determined by the dispersion dynamically modified by photogenerated plasma, thus allowing us to excite new frequencies in spectral ranges which are otherwise difficult to access. © 2017 American Physical Society.

description: Phase matching of high-order harmonic generation is investigated experimentally for various parameters in a semi-infinite gas-cell (SIGC) geometry. The optimized harmonic yield is identified using two different noble gases (Xe and He) and its parameter dependence is studied in a systematic way. Beside the straightforward setup of the SIGC, this geometry promises a high photon flux due to a large interaction region. Moreover, since the experimental parameters within this cell are known accurately, direct comparison to simulations is performed. Spectral splitting and blueshift of high-order harmonics are observed. © 2009 The American Physical Society.
title:  La differenza queer della traduzione a teatro : Il caso di Porci e cani di Caryl Churchill
Creators: name: Guarracino, Serena
Publisher: name: Università di Pisa
Year: 2019

description: Questo contributo esplora il ruolo della traduzione teatrale come forma di attivismo femminista e queer attraverso l’analisi di Porci e cani (2017), traduzione italiana di Pigs and Dogs (2016) della drammaturga britannica Caryl Churchill. Parte di un più ampio progetto per sostenere la ricezione di un’autrice ancora poco rappresentata sulle scene italiane, questa traduzione e la sua drammatizzazione ad opera di Bluemotion si inseriscono in un ampio scenario di ricerca sulla messa in scena dei corpi sessuati come pratica di resistenza politica. Rispetto alle esperienze maturate in Italia, questo testo sollecita però anche un confronto con la posizionalità del corpo queer rispetto alla linea del colore, e al suo ruolo nell’elaborazione del discorso nazionale e transnazionale sui diritti civili. La traduzione – sia sulla pagina che sulla scena – apre quindi uno spazio che permette di interrogare la differenza su diversi livelli (linguistico, corporeo, performativo), mostrando lo spazio e il tempo della performance al centro della ricerca di immaginari alternativi all’etero-patriarcato di marca coloniale, e che il teatro civile resta una delle forme di attivismo politico più significative nell’Italia contemporanea.

subject: Mental health services

description: Mental disorders are the greatest health challenges affecting young people, compared to medical health issues tend to affect people more when they’re older. Tertiary students experience even higher levels of mental disorder than other young people who were not tertiary students. Therefore, this thesis project aimed to understand how to promote resilience in tertiary education students. The results found that paying attention to the present and purpose in life had large impacts on improving resilience in tertiary education students. It also found that exercise, positive relations with others, humour, and acceptance of difficult circumstances helped to improve student resilience.

description: Solid-state nuclear magnetic resonance spectroscopy is an efficient technique to characterize dynamics and structure of materials. It has been widely used to elucidate ion dynamics in lithium ion conductors. Fast moving lithium ions are needed in energy storage devices, whereas slow ion motion is exploited in some materials used, for example, as blankets in fusion reactors. β-lithium gallium oxide (LiGaO2) is a slow Li+ ionic conductor similar to γ-lithium aluminum oxide (LiAlO2). In an ion conductor, in addition to the main diffusion process, localized motions (to-and-fro jumps) may be present. In the present work, with the help of solid-state NMR experiments, we report on the localized movements of Li+ ionic species in β-LiGaO2 in the temperature range between 300 K and 450 K. In this work, we have mainly extracted the peculiarities of ion dynamics from 7Li spin-alignment echo NMR measurements and the observation of the motional narrowing of the central transition signal of 7Li. © 2017 Walter de Gruyter GmbH, Berlin/Boston 2017.
CaLi2 superconductor under the pressure of 100 GPa: the thermodynamic critical field and the specific heat

description: In the paper, the thermodynamic properties of the CaLi$_2$ superconductor have been studied. It has been assumed the high value of the pressure: $p=100$ GPa. The thermodynamic critical field ($H_{C}$) and the specific heats for the superconducting and normal state ($C^{S}$ and $C^{N}$) have been obtained. The calculations have been made within the framework of the Eliashberg approach for the wide range of the Coulomb pseudopotential: $μ^{\star}\in<0.1,0.3>$. It has been shown that the low-temperature critical field and the specific heat jump at $T_{C}$ strongly decrease if $μ^{\star}$ increases. The value of the dimensionless ratio $R_{C}\equiv(C^{S}-C^{N})/C^{N}$ at the critical temperature differs significantly from the value predicted by the BCS model. In particular, the parameter $R_{C}$ decreases from 1.83 to 1.73 with the increase of the Coulomb pseudopotential value. In the paper, the interpolation formulas for the functions $T_{C}(μ^{\star})$ and $R_{C}(μ^{\star})$ have been also given.
