description: We performed Monte Carlo simulations of different properties of pulsar radio emission, such as: pulsar periods, pulse-widths, inclination angles and rates of occurrence of interpulse emission (IP). We used recently available large data sets of the pulsar periods P, the pulse profile widths W and the magnetic inclination angle alpha. We also compiled the largest ever database of pulsars with interpulse emission, divided into the double-pole (DP-IP) and the single-pole (SP-IP) cases. Their distribution on the P - Pdot diagram strongly suggests a secular alignment of the magnetic axis from the originally random orientation. We derived possible parent distribution functions of important pulsar parameters by means of the Kolmogorov-Smirnov significance test using the available data sets (P, W, alpha and IP), different models of pulsar radio beam rho = rho(P) as well as different trial distribution functions of pulsar period and the inclination angles. The best suited parent period distribution function is the log-normal distribution, although the gamma function distribution cannot be excluded. The strongest constraint on derived model distribution functions was the requirement that the numbers of interpulses were exactly (within 1sigma errors) at the observed level of occurrences. We found that a suitable model distribution function for the inclination angle is the complicated trigonometric function which has two local maxima, one near 0 deg and the other near 90 deg. The former and the latter implies the right rates of IP occurrence. It is very unlikely that the pulsar beam deviates significantly from the circular cross-section. We found that the upper limit for the average beaming factor fb describing a fraction of the full sphere (called also beaming fraction) covered by a pulsar beam is about 10%. This implies that the number of the neutron stars in the Galaxy might be underestimated.

description: Tsirelson's problem deals with how to model separate measurements in quantum mechanics. In addition to its theoretical importance, the resolution of Tsirelson's problem could have great consequences for device independent quantum key distribution and certified randomness. Unfortunately, understanding present literature on the subject requires a heavy mathematical background. In this paper, we introduce quansality, a new theoretical concept that allows to reinterpret Tsirelson's problem from a foundational point of view. Using quansality as a guide, we recover all known results on Tsirelson's problem in a clear and intuitive way.

description: We study the dynamics of planetary systems with two planets moving in the same plane, when frictional forces act on the two planets, in addition to the gravitational forces. The model of the general three-body problem is used. Different laws of friction are considered. The topology of the phase space is essential in understanding the evolution of the system. The topology is determined by the families of stable and unstable periodic orbits, both symmetric and non symmetric. It is along the stable families, or close to them, that the planets migrate when dissipative forces act. At the critical points where the stability along the family changes, there is a bifurcation of a new family of stable periodic orbits and the migration process changes route and follows the new stable family up to large eccentricities or to a chaotic region. We consider both resonant and non resonant planetary systems. The 2/1, 3/1 and 3/2 resonances are studied. The migration to larger or smaller eccentricities depends on the particular law of friction. Also, in some cases the semimajor axes increase and in other cases they are stabilized. For particular laws of friction and for special values of the parameters of the frictional forces, it is possible to have partially stationary solutions, where the eccentricities and the semimajor axes are fixed.

description: Irreversible logic circuits dissipate heat for every bit of information that is lost. Information is lost when the input vector cannot be recovered from its corresponding output vector. Reversible logic circuit naturally takes care of heating because it implements only the functions that have one-to-one mapping between its input and output vectors. Therefore reversible logic design becomes one of the promising research directions in low power dissipating circuit design in the past few years and has found its application in low power CMOS design, digital signal processing and nanotechnology. This paper presents the efficient approaches for designing reversible fast adders that implement carry look-ahead and carry-skip logic. The proposed 16-bit high speed reversible adder will include IG gates for the realization of its basic building block. The IG gate is universal in the sense that it can be used to synthesize any arbitrary Boolean-functions. The IG gate is parity preserving, that is, the parity of the inputs matches the parity of the outputs. It allows any fault that affects no more than a single signal readily detectable at the circuit's primary outputs. Therefore, the proposed high speed adders will have the inherent opportunity of detecting errors in its output side. It has also been demonstrated that the proposed design offers less hardware complexity and is efficient in terms of gate count, garbage outputs and constant inputs than the existing counterparts.

Research Statement for Emilie Collyer's essay "Wrestling with Mode and Meaning: the Play of Poetry in Theatre"

Publisher: name: RMIT University
Year: 2021
Subjects: subject: 190402 Creative Writing (incl. Playwriting)
subject: FOS: Arts (arts, history of arts, performing arts, music)

description: Background: In her 2016 State of Play essay, renowned Australian playwright Patricia Cornelius wrote, in relation to her work: ‘It’s the very heart of theatre – to disturb, to agitate, to make one feel uneasy about the shit of a world we live in.’ How might theatre enact this goal? In this essay I make the case that a key tool some playwrights use in order to ‘disturb and agitate’ is poetic language.Contribution: In analysing recent works of theatre where playwrights employ poetic language (that is, language that disturbs narrative flow or delivers narrative in unusual ways) they are engaging with a deliberate strategy to engage audiences on a socio-political level as well as an artistic level. Using plays that deal with subjects including poverty, incarceration of women, and the history of US slavery as my examples, I demonstrate that by bringing two forms (poetry and playwriting) into conversation with each other, new ways of hearing and understanding language are made possible – for those performing the works and for those receiving them as audiences. Writing about the creative and critical possibilities that are made possible when experimenting with form in this way contributes new insights to both critical analysis discourse about performance writing, and also to creative practice theory in regard to how playwrights work and how their choices have political impact.Significance: This essay was published by Cordite, one of Australia's leading platforms with a focus on poetry, poetics and poetic inquiry meant that my exploration of form was disseminated to a wide audience and became part of a public conversation about poetic and theatrical conventions. Cordite has published essays by leading Australian writers including Natalie Harkin, Michael Mohammed Ahmad, Toby Fitch and many more.

description: We consider moving particles in media with nonlinear friction and drive them by an asymmetric dichotomic Markov process. Due to different energy dissipations, during the forward and backward stroke, we obtain a mean non-vanishing directed flow of the particles. Starting with the stationary velocity distribution, we calculate the stationary current of particles, the variance and the relative variance in dependence on the degree of nonlinearity of the friction, on the asymmetry and for different strengths of friction. In two dimensions the particle performs diffusional motion, if in addition the direction of the asymmetric drive changes stochastically.

description: We present a sum-rule extraction of the decay constants of heavy-light mesons from the two-point correlator of pseudoscalar currents. To this end, we compare the perturbative expansions for the correlator and the decay constant performed in terms of either the pole mass or the running MS-bar mass of the heavy quark. The perturbative expansion expressed in terms of the pole mass exhibits no sign of convergence whereas reorganizing this very expansion in terms of the MS-bar mass yields a rather clear hierarchy of the perturbative contributions. Accordingly, the decay constants extracted from the pole-mass correlator turn out to be considerably smaller than those extracted from its MS-bar-mass counterpart. Then, making use of the OPE in terms of the MS-bar mass we derive the decay constants of heavy mesons with emphasis on acquiring control over the uncertainties in the decay constants, related both to the input QCD parameters and to the limited accuracy of the method of sum rules. Gaining this control has become possible due to the application of our novel procedure for extracting hadron observables based on dual thresholds which depend on the Borel parameter.

Scale-free graph processing on a NUMA machine
Creators: name: Aasawat, Tanuj Kr
Publisher: name: University of British Columbia
Year: 2018

description: The importance of high-performance graph processing to solve big data problems targeting high-impact applications is greater than ever before. Graphs incur highly irregular memory accesses which leads to poor data locality, load imbalance, and data-dependent parallelism. Distributed graph processing frameworks, such as Google's Pregel, that employs memory-parallel, shared-nothing systems have experienced tremendous success in terms of scale and performance. Modern shared-memory systems embrace the so called Non-Uniform Memory Access (NUMA) architecture which has proven to be more scalable (in terms of numbers of cores and memory modules) than the Symmetric Multiprocessing (SMP) architecture. In many ways, a NUMA system resembles a shared-nothing distributed system: physically distinct processing cores and memory regions (although, cache-coherent in NUMA). Memory accesses to remote NUMA domains are more expensive than local accesses. This poses the opportunity to transfer the know-how and design of distributed graph processing to develop shared-memory graph processing solutions optimized for NUMA systems (which is surprisingly little-explored). In this dissertation, we explore if a distributed-memory like middleware that makes graph partitioning and communication between partitions explicit, can improve the performance on a NUMA system. We design and implement a NUMA aware graph processing framework that treats the NUMA platform as a distributed system, and embraces its design principles; in particular explicit partitioning and inter-partition communication. We further explore design trade-offs to reduce communication overhead and propose a solution that embraces design philosophies of distributed graph processing system and at the same time exploits optimization opportunities specific to single-node systems. We demonstrate up to 13.9x speedup over a state-of-the-art NUMA-aware framework, Polymer and up to 3.7x scalability on a four-socket machine using graphs with tens of billions of edges.

description: We investigate theoretically soliton excitations and dynamics of their formation in strongly correlated systems of ultracold bosonic atoms in two and three dimensional optical lattices. We derive equations of nonlinear hydrodynamics in the regime of strong interactions and incommensurate fillings, when atoms can be treated as hard core bosons. When parameters change in one direction only we obtain Korteweg-de Vries type equation away from half-filling and modified KdV equation at half-filling. We apply this general analysis to a problem of the decay of the density step. We consider stability of one dimensional solutions to transverse fluctuations. Our results are also relevant for understanding nonequilibrium dynamics of lattice spin models.

description: Artificial Intelligence (AI) is anticipated to exert a considerable impact on the global Gross Domestic Product (GDP), with projections estimating a contribution of 13 trillion dollars by the year 2030 (IEEE Board of Directors, 2019). In light of this influence on economic, societal, and intellectual realms, it is imperative for Policy Makers to acquaint themselves with the ongoing developments and consequential impacts of AI. The exigency of their preparedness lies in the potential for AI to evolve in unpredicted directions should proactive measures not be promptly instituted.This paper endeavors to address a pivotal research question: " Do United States Policy Makers have a sufficient knowledgebase to understand Responsible AI in relation to Machine Learning to pass Artificial Intelligence legislation; and if they do not, how should a pedological instructional framework be created to give them the necessary knowledge?" The pursuit of answers to this question unfolded through the systematic review, gap analysis, and formulation of an instructional framework specifically tailored to elucidate the intricacies of Machine Learning. The findings of this study underscore the imperative for policymakers to undergo educational initiatives in the realm of artificial intelligence. Such educational interventions are deemed essential to empower policymakers with the requisite understanding for formulating effective regulatory frameworks that ensure the development of Responsible AI. The ethical dimensions inherent in this technological landscape warrant consideration, and policymakers must be equipped with the necessary cognitive tools to navigate these ethical quandaries adeptly.In response to this exigency, the present study has undertaken the design and development of an instructional framework. This framework is conceived as a strategic intervention to address the evident cognitive gap existing among policymakers concerning the nuances of AI. By imparting an understanding of AI-related concepts, the framework aspires to cultivate a more informed and discerning governance ethos among policymakers, thus contributing to the responsible and ethical deployment of AI technologies.

description: The blazar 1ES1218+30.4 has been previously detected by the VERITAS and MAGIC telescopes in the very high energies. The new detection of VERITAS from December 2008 to April 2009 proves that 1ES1218+30.4 is not static, but shows short-time variability. We show that the time variability may be explained in the context of a self-consistent synchrotron-self Compton model, while the long time observation do not necessarily require a time-resolved treatment. The kinetic equations for electrons and photons in a plasma blob are solved numerically including Fermi acceleration for electrons as well as synchrotron radiation and Compton scattering. The light curve observed by VERITAS can be reproduced in our model by assuming a changing level of electron injection compared to the constant state of 1ES1218+30.4. The multiwavelength behaviour during an outburst becomes comprehensible by the model. The long time measurements of VERITAS are still explainable via a constant emission in the SSC context, but the short outbursts each require a time-resolved treatment.

description: Half-lives of radionuclides span more than 50 orders of magnitude. We characterize the probability distribution of this broad-range data set at the same time that explore a method for fitting power-laws and testing goodness-of-fit. It is found that the procedure proposed recently by Clauset et al. [SIAM Rev. 51, 661 (2009)] does not perform well as it rejects the power-law hypothesis even for power-law synthetic data. In contrast, we establish the existence of a power-law exponent with a value around 1.1 for the half-life density, which can be explained by the sharp relationship between decay rate and released energy, for different disintegration types. For the case of alpha emission, this relationship constitutes an original mechanism of power-law generation.

description: The development of university cooperation at the European level is closely related both to the needs of the single market and to those of an economic and social cohesion functional to a more effective protection of the rights of European citizens.


The recent launch of EU university alliances is part of this framework, although the absence of legal instruments explicitly conceived for institutionalised cooperation could undermine the success of the action of alliances.


The EU competence in higher education is limited to the support, coordination, and supplement of member state actions (art. 6TFEU). The absence of a harmonising competence circumscribes the possibilities of EU intervention and especially prevents the provision of EU degrees which could replace national diplomas.


However, the allocation of funding allows policies capable of effectively influencing the systems of member states (see for instance the EU experience in common agricultural policies sector).


In this context, the limits of the existing tools could be almost partially overpassed by the adoption of new regulations or directives, to allow an institutionalised cooperation between universities.


The existing solutions offered by the EU legal system are not fully satisfactory, nonetheless, some of them could be useful: among these, the European Economic Interest Grouping (EEIG) is especially interesting.

description: We explore the ground states and dynamics of ultracold atomic droplets in the crossover region from three to two dimensions by solving the two-dimensional and the quasi two-dimensional extended Gross-Pitaevskii equations numerically and with a variational approach. By systematically comparing the droplet properties, we determine the validity regions of the pure two-dimensional description, and therefore the dominance of the logarithmic nonlinear coupling, as a function of the sign of the averaged mean-field interactions and the size of the transverse confinement. One of our main findings is that droplets become substantially extended upon transitioning from negative-to-positive averaged mean-field interactions. This is accompanied by a significant reduction of their binding energies which are approximately inversely proportional to the square of their size. To explore fundamental dynamical properties in the crossover region, we study interaction quenches and show that the droplets perform a periodic breathing motion for modest quench strengths, while larger quench amplitudes lead to continuous expansion exhibiting density ring structures. We also showcase that it is possible to form complex bulk and surface density patterns in anisotropic geometries following the quench. Since we are working with realistic parameters, our results can directly facilitate future experimental realizations.
How unusual are the Shapley Supercluster and the Sloan Great Wall?

description: We use extreme value statistics to assess the significance of two of the most dramatic structures in the local Universe: the Shapley supercluster and the Sloan Great Wall. If we assume that Shapley (volume ~ 1.2 x 10^5 (Mpc/h)^3) evolved from an overdense region in the initial Gaussian fluctuation field, with currently popular choices for the background cosmological model and the shape and amplitude sigma8 of the initial power spectrum, we estimate that the total mass of the system is within 20 percent of 1.8 x 10^16 Msun/h. Extreme value statistics show that the existence of this massive concentration is not unexpected if the initial fluctuation field was Gaussian, provided there are no other similar objects within a sphere of radius 200 Mpc/h centred on our Galaxy. However, a similar analysis of the Sloan Great Wall, a more distant (z ~ 0.08) and extended concentration of structures (volume ~ 7.2 x 10^5 (Mpc/h)^3) suggests that it is more unusual. We estimate its total mass to be within 20 percent of 1.2 x 10^17 Msun/h; even if it is the densest such object of its volume within z=0.2, its existence is difficult to reconcile with Gaussian initial conditions if sigma8 < 0.9. This tension can be alleviated if this structure is the densest within the Hubble volume. Finally, we show how extreme value statistics can be used to address the likelihood that an object like Shapley exists in the same volume which contains the Great Wall, finding, again, that Shapley is not particularly unusual. It is straightforward to incorporate other models of the initial fluctuation field into our formalism.

description: At low strain, SiGe films on Si substrates undergo a continuous nucleationless morphological evolution known as the Asaro-Tiller-Grinfeld instability. We demonstrate experimentally that this instability develops on Si(001) but not on Si(111) even after long annealing. Using a continuum description of this instability, we determine the origin of this difference. When modeling surface diffusion in presence of wetting, elasticity and surface energy anisotropy, we find a retardation of the instability on Si(111) due to a strong dependence of the instability onset as function of the surface stiffness. This retardation is at the origin of the inhibition of the instability on experimental time scales even after long annealing.

description: The injection and evolution of turbulence in the intergalactic medium is studied by means of mesh-based hydrodynamical simulations, including a subgrid scale (SGS) model for small-scale unresolved turbulence. The simulations show that the production of turbulence has a different redshift dependence in the intracluster medium (ICM) and the warm-hot intergalactic medium (WHIM). We show that turbulence in the ICM is produced chiefly by merger-induced shear flows, whereas the production in the WHIM is dominated by shock interactions. Secondly, the effect of dynamical pressure support on the gravitational contraction has been studied. This turbulent support is stronger in the WHIM gas at baryon overdensities 1 < delta < 100, and less relevant for the ICM. Although the relative mass fraction of the gas with large vorticity is considerable (52% in the ICM), we find that for only about 10% in mass this is dynamically relevant, namely not associated to an equally large thermal pressure support. According to this result, a significant non-thermal pressure support counteracting the gravitational contraction is a localised characteristic in the cosmic flow, rather than a widespread feature.

description: The testing time for a system-on-chip(SOC) largely depends on the design of test wrappers and the test access mechanism(TAM).Wrapper/TAM co-optimization is therefore necessary to minimize SOC testing time . In this paper, we propose an efficient algorithm to construct wrappers that reduce testing time for cores. We further propose a new approach for wrapper/TAM co-optimization based on two-dimensional rectangle packing. This approach considers the diagonal length of the rectangles to emphasize on both TAM widths required by a core and its corresponding testing time.

Transmedia Narratives and Social Networks: Peaky Blinders' Television Fiction

description: Digital media expanded the scenarios in which people watch television and the communication contexts where fans comment on their content. This work focuses on the conversations between Spanish speakers that take place on the Internet about the Peaky Blinders TV series.


We focus on analysis of the discourse generated from the series’ content in social networks, where spectators converse with one another and on analysis of other, creative practices, which help to develop the transmedia narrative but are generated by the spectators themselves. This is known as fan fiction, cosplay or crossover.


We combine big data (Kitchin, 2014), to extract digital texts, and small data to analyze the construction of meanings from the perspective of discourse analysis (Gee, 2014). Big data were collected during the recent premiere of the fifth season in Spain, from 14 March to 15 June 2020 (3 months of which coincided with Covid-19 lockdown).The texts appeared on Twitter, Facebook, and YouTube, as well as in forums, comments, and other digital information. We dynamically defined 268 categories during the data collection stage. This study includes only those that the research team considered were more relevant, facilitating in-depth analysis of the conversations through discourse analysis.


The results discuss how participants construct narratives that we interpret from a triple model. First, digital and situated storytelling (Ryan, 2019) through reconstruction of the contents and formats of the series by fans (Lacasa, 2020). Second, digital media and the presence of multi-platforms, which have generated transmedia strategies (Kavoori et al., 2017 (Kavoori, 2017)).


The study establishes the relationships between these multiple platforms and how audiences are present there. Third, digital contexts that generate conversations, creating dialogue between cultural industries and TV series followers.

Acousmatic Foley: Son-en-Scène
Creators: name: Pinheiro, Sara
Publisher: name: International Journal of Film and Media Arts

description: “Acousmatic Foley” is practice-based research on sound dramaturgy stemming from musique concrète and Foley Art. This article sets out a theory based on the concept of “son-en-scène”, which forms the sonic content of the mise-en-scène, as perceived (esthesic sound). The theory departs from the well-known features of a soundscape (R. M. Schafer, 1999) and the listening modes in film as asserted by Chion (1994), in order to arrive at three main concepts: sound-prop, sound-actor and sound-motif. Throughout their conceptualization, the study theorizes a sonic dramaturgy that focuses on the sounds themselves and their practical influence on film's story-telling elements. For that, it conveys an assessment of sound in film-history based on the “montage of attractions” and foley art, together with the principles of acousmatic listening. This research concludes that film-sound should be to sound designers what a “sonorous object” is to musique concrète, albeit conveying all sound’s fictional aspects.

description: We present reflected light spectral observations from 0.4 to 2.5 micron of 24 asteroids chosen from the population of asteroids initially classified as Tholen X-type objects (Tholen, 1984). The X complex in the Tholen taxonomy comprises the E, M and P classes which have very different inferred mineralogies but which are spectrally similar to each other, with featureless spectra in visible wavelengths. The data were obtained during several observing runs in the 2004-2007 years at the NTT, TNG and IRTF telescopes. We find a large variety of near-infrared spectral behaviors within the X class, and we identify weak absorption bands in spectra of 11 asteroids. Our spectra, together with albedos published by Tedesco et al. (2002), can be used to suggest new Tholen classifications for these objects. In order to constrain the possible composition of these asteroids, we perform a least-squares search through the RELAB spectral database. Many of the best fits are consistent with meteorite analogue materials suggested in the published literature. In fact, we find that 7 of the new M-types can be fit with metallic iron (or pallasite) materials, and that the low albedo C/P-type asteroids are best fitted with CM meteorites, some of which have been subjected to heating episodes or laser irradiation. Finally, we consider and analyse the sample of the X-type asteroids we have when we combine the present observations with previously published observations for a total of 72 bodies.

description: Improving software process to achieve high quality in a software development organization is the key factor to success. Bangladeshi software firms have not experienced much in this particular area in comparison to other countries. The ISO 9001 and CMM standard has become a basic part of software development. The main objectives of our study are: 1) To understand the software development process uses by the software developer firms in Bangladesh 2) To identify the development practices based on established quality standard and 3) To establish a standardized and coherent process for the development of software for a specific project. It is revealed from this research that software industries of Bangladesh are lacking in target set for software process and improvement, involvement of quality control activities, and standardize business expertise practice. This paper investigates the Bangladeshi software industry in the light of the above challenges.

Re[PLAY] As imagens televisionadas do futebol como material videográfico

description: The space dedicated to football in several and different television programs in which this industry is debated is often taken by the search for the “true image”, the image that proves the origin of the penalty, the image that supports the warning of the red card, or the image that betrays the irregularity of the goal. All these moments are, today, the target of thousands of hours of commentary in the television space, demonstrating a huge bias on the power of images repeated ad nauseum, there even being a moment where some formats of this type of program were questioned due to the « noise” and the “toxicity” that arose in such confrontations of ideas. This investigation aims to create an artistic object (filmic/video/installation) that explores the condition of the manipulable image-file that arises in this type of programs, and where it is often scrutinized, edited, altered, decontextualized, etc., in an incessant search for determination of a truth-moment.
