description: We recently developed a new general relativistic magnetohydrodynamic code with adaptive mesh refinement that evolves the electromagnetic (EM) vector potential (A) instead of the magnetic fields directly. Evolving A enables one to use any interpolation scheme on refinement level boundaries and still guarantee that the magnetic field remains divergenceless. As in classical EM, a gauge choice must be made when evolving A, and we chose a straightforward "algebraic" gauge condition to simplify the A evolution equation. However, magnetized black hole-neutron star (BHNS) simulations in this gauge exhibit unphysical behavior, including the spurious appearance of strong magnetic fields on refinement level boundaries. This spurious behavior is exacerbated when matter crosses refinement boundaries during tidal disruption of the NS. Applying Kreiss-Oliger dissipation to the evolution of the magnetic vector potential A slightly weakens this spurious magnetic effect, but with undesired consequences. We demonstrate via an eigenvalue analysis and a numerical study that zero-speed modes in the algebraic gauge, coupled with the frequency filtering that occurs on refinement level boundaries, are responsible for the creation of spurious magnetic fields. We show that the EM Lorenz gauge exhibits no zero-speed modes, and as a consequence, spurious magnetic effects are quickly propagated away, allowing for long-term, stable magnetized BHNS evolutions. Our study demonstrates how the EM gauge degree of freedom can be chosen to one's advantage, and that for magnetized BHNS simulations the Lorenz gauge constitutes a major improvement over the algebraic gauge.

The transformative potential of participatory politics : energy planning and emergent sustainability in British Columbia, Canada
Creators: name: Dusyk, Nichole
Publisher: name: University of British Columbia
Year: 2013

description: This research examines the potential for local engagement in provincial energy planning and the contribution it might make to an energy transition. Combining a social worlds framework with the concept of hybrid forums, I develop the thesis that participation can facilitate sociotechnical change by facilitating the exploration of new identities and the collective reframing of problems and their solutions. This is what I call the transformative potential of participatory politics. I explore and elaborate this thesis using a discourse analysis of the provincial clean energy policy and two case studies of communities in British Columbia: Fort St. John and Dawson Creek. The discourse analysis examines the evolution of the clean energy storyline, introduced in 2007, and how it serves to position actors and technologies in the province. The analysis shows how the storyline, although integrating an environmental imperative into policy discourse, reproduces the trajectory and inertia of historical energy development. The case study analysis examines municipal energy planning and one large-scale renewable energy project in each of the communities: the proposed Site C Hydroelectric Project in Fort St. John and the Bear Mountain Wind Park in Dawson Creek. My analysis describes the mechanisms and sites of collective negotiation and how in each case, participatory processes have altered technologies, collective identities, and the framing of energy planning. The case studies support the thesis that participatory politics can contribute to energy transitions by altering the social and material characteristics of energy networks. In so doing, they add nuance to our understanding of what participatory energy governance can contribute and the circumstances in which it is effective. This includes findings that highlight the significance of the institutional, political, and infrastructural context in which participatory governance unfolds leading to the conclusion that participation, although potentially transformative, is not a panacea. In conclusion, I situate my findings in relation to the concept of procedural sustainability arguing that by making room for collective negotiation, participatory politics can help move beyond the apparent antagonism of implementing renewable energy projects toward a potentially more productive approach of localizing energy projects and collectively constructing sustainability discourses and practices.
Riscritture appropriate e approprianti. Traduzione e revisione del testo letterario

Subjects: traduzione; revisione; riscrittura appropriata/appropriante; ibrido

description: Both the translation and the revised version of a literary text give rise to similar issues, for in both cases one can adopt a strategy of either appropriate rewriting or appropriating rewriting. In the former case, the tendency is to respect the properties and peculiar qualities of the Other; in the latter, the tendency is to manipulate and distort the text, to reduce the Other to the Self and not to contemplate the creative potentialities of contaminated language. Italian publishing houses seem to be afraid of hybridity: homologation, order, syntactical and lexical propriety appear more alluring. But it is the two elements of the foreign and the new enclosed in the concept of hybridity that allow the translator to challenge the cultural values of the publishing establishment. Even if liminal space is an unexplored area by the Italian publishing sector, the concept of in-betweeness is very useful for translation, in particular post-colonial translation. One of the fields in which the creative potential of liminal space can be fully explored by translators, revisers and publishers alike is the field of contact languages, for pidgins and creoles move freely in the interstitial zone. An example taken from Jean Rhys’ Wide Sargasso Sea (1966), and its comparison with Adriana Motti’s translation, published by Adelphi in 1971, allow us to show what is meant by appropriate and appropriating rewriting.

Towards the Evolution of Vertical-Axis Wind Turbines using Supershapes

description: We have recently presented an initial study of evolutionary algorithms used to design vertical-axis wind turbines (VAWTs) wherein candidate prototypes are evaluated under approximated wind tunnel conditions after being physically instantiated by a 3D printer. That is, unlike other approaches such as computational fluid dynamics simulations, no mathematical formulations are used and no model assumptions are made. However, the representation used significantly restricted the range of morphologies explored. In this paper, we present initial explorations into the use of a simple generative encoding, known as Gielis superformula, that produces a highly flexible 3D shape representation to design VAWT. First, the target-based evolution of 3D artefacts is investigated and subsequently initial design experiments are performed wherein each VAWT candidate is physically instantiated and evaluated under approximated wind tunnel conditions. It is shown possible to produce very closely matching designs of a number of 3D objects through the evolution of supershapes produced by Gielis superformula. Moreover, it is shown possible to use artificial physical evolution to identify novel and increasingly efficient supershape VAWT designs.

description: This study constitutes a further development of my doctoral thesis For a Methodology of Translation Criticism: the Italian Translations of The Secret Sharer by Joseph Conrad, where the importance of the translational metalanguage was discussed. In the first section of this paper several definitions of translation and rewriting (mainly by Eco, Bassnet and Lefevere, and Torop) are reviewed, thus highlighting contrasting positions concerning the very definition thereof. The main characteristics of an Italian version of The Secret Sharer for young readers – L’ospite segreto translated by Pieroni and Liberio – are listed, showing the editing and translating strategies underlying this specific text in which the target reader is very different from the source reader. The role of the target reader in translation practice is eventually examined, by stressing the vital status of metalanguage in translation criticism.

description: We present a new scenario for the cooling of compact stars considering the central source of Cassiopeia A (Cas A). The Cas A observation shows that the central source is a compact star that has high effective temperature, and it is consistent with the cooling without exotic phases. The observation also gives the mass range of $M \geqslant 1.5 M_\odot$, which may conflict with the current plausible cooling scenario of compact stars. There are some cooled compact stars such as Vela or 3C58, which can be barely explained by the minimal cooling scenario, which includes the neutrino emission by nucleon superfluidity (PBF). Therefore, we invoke the exotic cooling processes, where a heavier star cools faster than lighter one. However, the scenario seems to be inconsistent with the observation of Cas A. Therefore, we present a new cooling scenario to explain the observation of Cas A by constructing models that include a quark color superconducting (CSC) phase with a large energy gap; this phase appears at ultrahigh density region and reduces neutrino emissivity. In our model, a compact star has CSC quark core with a low neutrino emissivity surrounded by high emissivity region made by normal quarks. We present cooling curves obtained from the evolutionary calculations of compact stars: while heavier stars cool slowly, and lighter ones indicate the opposite tendency without considering nucleon superfluidity. Furthermore, we show that our scenario is consistent with the recent observations of the effective temperature of Cas A during the last 10 years, including nucleon superfluidity.

Il concetto di numero nella fondazione dell'aritmetica in Kant e Dedekind
Creators: name: Ruvidotti, Lucio
Publisher: name: Rivista Italiana di Filosofia Analitica Junior
Year: 2011

description: In this article we compare Kant and Dedekind position about foundation of arithmetic and concept of number. This paper is not focused on an exhausting presentation of these concepts and not even on a historical review. We want to show that Dedekind’s approach towards the logical and mathematical foundation of arithmetics seems to be delegitimating if compared with the one of philosphical foundation as it’s been conceived by Kant. Nonetheless, the foundation of arithmetics expressed by Kant, is clearly connected to the entire system of critics and assume a specific meaning that is wider than Dedekind ones. A logical clarification of arithmetics foundations does not deal with the question like the role of mathematics in the knowledge system and his relationship with empirical science. Moreover, it seems rightful to treat the problem within the frame of a philosophical research. In conclusion, we conclude with the proposal of a new evaluation of trascendental logic, in a weaker sense than the one originally intended by Kant, meant to be a philosophical discipline that tries to research refine such questions and possibly find responses for them. We present some considerations about the ontological status of numbers within the theories of Kant and Dedekind.

In particular, we prove that the all genus, virtual dimension zero Gromov-Witten theory of the blowup of P^3 at points coincides with that of the blowup at points of P^1xP^1xP^1, for non-exceptional classes. We observe a toric symmetry of the Gromov-Witten theory of P^1xP^1xP^1 analogous and intimately related to Cremona symmetry of P^3. Enumerative applications are given.

description: This thesis analyzes the pendant prints from the book The Mistake off Matrimonij (1641)by Dutch artist Crispijn de Passe the Younger (or Crispijn van de Passe the Younger) (1594/95−1670) and is dually concerned with both their production and reception. The volume’s introductory pages explicitly call out the “shameful” behaviors of European citizens who enabled or engaged in adultery and the paired images that follow attempt to persuade a reader that the represented individuals, and their illicit sexual actions, existed and were thus a threat to society. With select case studies of the volume’s pairings, the project argues that the visualization of the figures was compelled by and propelled contemporary marital surveillance networks and popular media’s gendered marital stereotypes. Chapter One considers the volume’s pictorial presentation of gossip not as a report of social anecdotes, but as images within and onto which social judgments were made. Chapter Two expands into a gender analysis to argue that the book’s characters were influenced by gendered tropes and expectations expressed in early modern imagery and nuptial literature. The latter chapter also addresses the representation of the figures in relation to “other” social identities, such as race and disability. Audience is a vital interpretive context, as the volume emphatically demonstrates its interest in a range of readers, most notably in its introductory pages, multilingual texts, and transnational subject matter. This project concludes that the book’s intended messaging was not strictly didactic, and that the volume established a discursive relationship with agentic readers.

description: We present imaging simulations of the Sunyaev-Zel'dovich effect of galaxy clusters for the Atacama Large Millimeter/submillimeter Array (ALMA) including the Atacama Compact Array (ACA). In its most compact configuration at 90GHz, ALMA will resolve the intracluster medium with an effective angular resolution of 5 arcsec. It will provide a unique probe of shock fronts and relativistic electrons produced during cluster mergers at high redshifts, that are hard to spatially resolve by current and near-future X-ray detectors. Quality of image reconstruction is poor with the 12m array alone but improved significantly by adding ACA; expected sensitivity of the 12m array based on the thermal noise is not valid for the Sunyaev-Zel'dovich effect mapping unless accompanied by an ACA observation of at least equal duration. The observations above 100 GHz will become excessively time-consuming owing to the narrower beam size and the higher system temperature. On the other hand, significant improvement of the observing efficiency is expected once Band 1 is implemented in the future.

L'incompatibilità tra il paradigma fregeano e l'esternismo di Tyler Burge
Creators: name: Costa, Davide
Publisher: name: Rivista Italiana di Filosofia Analitica Junior
Year: 2011

description: The paper suggests an analysis concerning the supposed compatibility between Frege’s intuitive criterion for difference (i.e. if it is possible, for a subject S, to believe p and not believe q, then the content of p is different from the content of q) and an externalist perspective in determining the content of beliefs. Although initially endorsing the fregean criterion, Burge (1979a) claims that the individual competence is negligible for matters concerning reference: the competence of the linguistic community is what solely must be taken into account for it. But this inevitably leads to the rejection of Frege’s criterion. The discussion pursues Burge’s thought, showing how even a more sophisticated point of view, such as Burge (1982), leads to the same conclusion, nonetheless depicting Burge’s form of externalism as thoroughly problematical.

description: In this paper we study the critical behaviour of the fully-connected p-colours Potts model at the dynamical transition. In the framework of Mode Coupling Theory (MCT), the time autocorrelation function displays a two step relaxation, with two exponents governing the approach to the plateau and the exit from it. Exploiting a relation between statics and equilibrium dynamics which has been recently introduced, we are able to compute the critical slowing down exponents at the dynamical transition with arbitrary precision and for any value of the number of colours p. When available, we compare our exact results with numerical simulations. In addition, we present a detailed study of the dynamical transition in the large p limit, showing that the system is not equivalent to a random energy model.

Evolution, Moral Justification, and Moral Realism

description: Does evolutionary theory have the potential to undermine morality? In his book The Evolution of Morality, Richard Joyce (2006) argues for a positive answer. He contends that an evolutionary account of morality would undermine moral judgements and lend support to moral scepticism. I offer a critique of Joyce’s argument. As it turns out, his case can be read in two different ways. It could be
construed as an argument to establish a general scepticism about the justification of moral judgements. Or it could be read as an argument that targets only a particular meta-ethical position, namely moral realism. My claim is that it fails on both interpretations. There is no reason to believe that evolutionary considerations undermine morality.

Sexual health outcomes of a yoga therapy intervention for breast cancer survivors
Creators: name: Carson, Anna
Publisher: name: University of British Columbia
Year: 2013

description: Background: Breast cancer treatment has improved survival prognoses; as such, the late effects of breast cancer and its treatment have become an increasingly important field of inquiry. Although the prevalence of sexual health problems among breast cancer survivors (BCSs) varies, they are among the most distressing side effects associated with breast cancer and its treatment. However, effective interventions for sexual health issues within this population have yet to be established. Yoga therapy, a health promoting, non-invasive, and non-pharmaceutical intervention, holds promise as an effective and acceptable approach to sexual health problems after breast cancer and its treatment. Methods: Using a controlled pre-post design, changes in sexual health outcome scores were assessed for participants in a three-armed yoga therapy intervention (YTI) study (Anusara yoga, Iyengar yoga, or waitlisted control). Multiple linear regression analysis was guided by a modified version of a pre-established framework comprising sexual health predictors in BCSs, in order to assess the strength of the relationship between YTI participation and changes in sexual health outcome scores. A subset analysis of only partnered participants was carried out because of the established importance of partnered relationships to sexual health. Results: Participation in Anusara yoga was significantly associated with an increase of 14 (of 91) points (p-value<0.05) on the Overall Sexual Health scale in partnered participants (AR²=0.43, p=0.001). Both age (p<0.001) and physical function (p<0.05) were also significant predictors in this model. Participation in Iyengar yoga was significantly associated with an increase in 3 (of 28) points (p<0.05) on the Sexual Function scale among all participants (AR²=0.23, p=0.026). Both age (p<0.05) and physical function (p<0.05) were also significant predictors. Conclusions: This YTI study showed evidence of effect in terms of improved Overall Sexual Health scores among partnered Anusara participants and increased Sexual Function among all Iyengar participants. Although preliminary, these results indicate that yoga therapy may be an effective, gentle, and safe intervention for BCSs who experience sexual health problems. Future interventions with larger, randomized samples, comprised by and designed specifically for BCSs with self-identified sexual health complaints, are recommended based upon our results.

description: L’autismo è un disturbo pervasivo dello sviluppo neuropsicologico che interessa all’incirca un bambino su mille. Purtroppo, si tratta di un dato destinato ad aumentare, anche per via dell’interesse mediatico e scientifico che questa patologia è stata capace di richiamare intorno a sé. Da un lato, infatti, sono aumentate le richieste di screening presso i numerosi centri che monitorano questa complessa patologia neurologica e dall’altro sono migliorate le tecniche di diagnosi che sempre più spesso si avvalgono di esami genetici all’avanguardia in aggiunta alle ormai classiche interviste psicologiche. L’autismo pone, dunque, serie questioni all’attenzione della ricerca scientifica sia nel vasto campo delle neuroscienze che in quello della neuropsichiatria e della psicologia clinica. Ebbene: quel settore della filosofia che guarda alla scienza con interesse particolare, non può che seguire con partecipazione i progressi nella spiegazione di questa misteriosa patologia che, attualmente, resta un vero e proprio rompicapo per tutti coloro che hanno a che fare con la complessità dell’organizzazione cerebrale dell’essere umano.

description: An analysis of the cross section for hadronic production of gluino-squark pairs close to threshold is presented. Within the framework of non-relativistic QCD a significant enhancement compared to fixed order perturbation theory is observed which originates from the characteristic remnants of the gluino-squark resonances below the nominal pair threshold. The analysis includes all colour configurations of S-wave gluino-squark pairs, i.e. triplet, sextet and 15 representation. Matching coefficients at leading order are separately evaluated for all colour configurations. The dominant QCD corrections, arising from initial- and final-state radiation are included. The non-relativistic dynamics of the gluino pair is solved by calculating the Green's function in Next-to-Leading Order (NLO). The results are applied to benchmark scenarios, based on Snowmass Points and Slopes (SPS). As a consequence of the large decay rate of at least one of the constituents squark or gluino annihilation decays of the bound state (\tilde{g}\tilde{q})\rightarrow gq, qγ, qZ or q'W^{\pm} are irrelevant. Thus the signatures of gluino-quark production below and above the nominal threshold are identical. Numerical results for the cross section at the Large Hadron Collider (LHC) at \sqrt{s}=7 TeV and 14 TeV are presented. The enhancement of the total cross section through final state interaction amounts to roughly 3%.

Second-order differential uniformity for cryptographic Boolean functions
Creators: name: O'Reilly, Connor
Publisher: name: Loughborough University
Year: 2025

description: We discuss the second-order differential uniformity of vectorial Boolean functions. The closely related notion of second-order zero differential uniformity has recently been studied in connection to resistance to the boomerang attack. We prove that monomial functions with univariate form $x^d$ where $d=2^{2k}+2^k+1$ and $\gcd(k,n)=1$ have optimal second-order differential uniformity. Computational results suggest that, up to affine equivalence, these might be the only optimal cubic power functions. We begin work towards generalising such conditions to all monomial functions of algebraic degree 3. We also discuss further questions arising from computational results.
Electromigration occurrences and its effects on metallic surfaces submitted to high electromagnetic field : A novel approach to breakdown in accelerators

description: The application of a high electrical field on metallic surfaces leads to the well described phenomena of breakdown. In the classical scenario, explosive electron emission (EEE), breakdown (BD) originates from an emitting site (surface protrusion). The conditioning process consists of "burning" the emitting sites one after another and numerous observations exhibit surfaces covered with molten craters that more or less overlap. When dealing with RF cavities for accelerators, where increasingly fields are now sought, one can legitimately wonder if other physical phenomena should also be taken into account. In particular, we believe that electromigration, especially at surfaces or grain boundaries cannot be neglected anymore at high field (i.e. 50-100 MV/m). Many publications in the domain of liquid metal emission sources show that very stable and strong emission sources, either ions or electrons, build up on metallic surfaces submitted to electrical fields through a mechanism that is slightly different from the usual localized breakdown evoked in accelerators. This mechanism involves the combination of electromigration and collective motion of surface atoms. The recent results obtained on 30 GHz CLIC (Compact Linear Collider) accelerating structures, altogether with the data exposed hereafter have led us to propose a complementary scenario (pre-plasma apparition), based on electromigration, which could explain early melting of large areas of the surface.

Year: 2025

description: Based on formalism of the recently proposed pSPSS model for heavy neutralleptons (HNLs), we study the possibility of measuring the oscillations of HNLs at the FCC-ee with a parametrised detector simulation. We further discuss strategies for discriminationof the Dirac or Majorana nature of the HNLs, and we assess how this strategy can be appliedto constrain the parameters of the model in the parameter space in which the oscillationmay not be observable.

description: We present a new shear free model for the gravitational collapse of a spherically symmetric charged body. We propose a dissipative contraction with radiation emitted outwards. The Einstein field equations, using the junction conditions and an ansatz, are integrated numerically. A check of the energy conditions is also performed. We obtain that the charge delays the black hole formation and it can even halt the collapse.

Development, validation and application of analytical methods to measure prognostic biomarkers in patients receiving on-pump coronary artery bypass grafting surgery

Publisher: name: University of British Columbia
Year: 2013

description: Temporary interception and then re-infusion of oxygenated blood into heart during on-pump Coronary Artery Bypass Grafting (CABG) surgery causes ischemia-reperfusion injury (IRI). Propofol is an intravenous anesthetic agent that maybe potentially cardioprotective against IRI. This thesis presents the development, validation and application of analytical methods for monitoring propofol and a series of prognostic biomarkers in hope of identifying contributory factors to IRI and propofol cardioprotection. I developed a Capillary Electrophoresis (CE) method to quantify propofol concentrations in blood. Propofol concentrations in the μg/mL range were measured from 400 μL samples. A dosefinding study using this method determined a practical infusion rate of 120 μg•kg•min⁻¹ to achieve the target blood concentration of 5 μg•mL⁻¹. To measure the oxidative stress biomarker, 15-F₂t₋isoprostane, the nitrosative stress biomarker, 3-nitrotyrosine, the myocardial protective factor, adenosine, and the cardiovascular risk factor, asymmetric dimethylarginine (ADMA), I developed simple, sensitive and robust Liquid Chromatography-Mass Spectrometry (LC-MS) or Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) methods. Briefly, a basic mobile phase and base-resistant column were used for the LC-MS analysis of 15-F₂t-isoprostane. A one-step solid phase extraction and pentafluorophenyl (PFP) core-shell column were employed for the LC-MS/MS analysis of 3- nitrotyrosine. A Strong Cation Exchange (SCX) solid phase extraction and modifier-free mobile phase were implemented for the LC-MS/MS analysis of adenosine. A new derivatization method to enable baseline separation of ADMA and its regio-isomer symmetric dimethylarginine (SDMA) was developed for the ADMA LC-MS/MS quantitation. Performance parameters for these methods, including linearity, precision, accuracy, Limit of Detection (LOD), Limit of Quantitation (LOQ), Lower Limit of Quantitation (LLOQ) and stability were found satisfactory. Concentrations of 15-F₂t₋isoprostane, 3-nitrotyrosine and adenosine were found to rise after on-pump CABG surgery. However, these changes were not able to explain the cardioprotective effect of propofol. Nonetheless, the correlations of 15-F₂t₋isoprostane with diabetes, glucose concentration and PTEN level were significant. Patients with low cardiac output syndrome experienced more 3-nitrotyrosine increase than patients without this syndrome. The basal adenosine level was found to increase more in patients with low left ventricular ejection fraction. These findings and the underlying methodologies are important for identifying new prognostic biomarkers.
