description: Nas últimas três décadas renasce o reconhecimento da relevância de empresas de pequeno porte, principalmente por sua capacidade de gerar emprego e possibilitar uma melhor condição para o desenvolvimento local, contribuindo para melhorar a distribuição de renda. A comprovação de que aglomeração de empresas de pequeno porte gera condições de competitividade, fez com que vários países passassem a adotar uma política pública de desenvolvimento local voltada para a promoção da interatividade entre essas empresas e instituições públicas e privadas. No Brasil vários estados e municípios já vêm adotando a estratégia de desenvolvimento fundamentado nas aglomerações das MPEs. Este trabalho visa mostrar o que é um arranjo produtivo local, identificar os principais fatores que devem existir dentro de um arranjo para que este alcance um grau mais elevado de sucesso, analisando os fatores de cooperação, capital social, aprendizado, competitividade e governança. Também será apresentado um estudo de caso com os produtores de hortaliças e flores do Projeto São Tomé, no município de Aratuba na região do Maciço de Baturité com intuito de identificar o estágio em que esse arranjo produtivo se encontra e analisar as dificuldades enfrentadas por esses produtores. Por fim serão apontadas sugestões que possam ajudar a enfrentar os gargalos identificados no arranjo.---------------------In the last three decades reborn recognition of the importance of small-size, mainly by its ability to generate employment and provide better conditions for local development, contributing to improving the distribution of income. The proof that agglomeration of smallsize creates conditions of competitiveness has caused several countries to become adopt a public policy for local development focused on the promotion of interactivity between these companies and public and private institutions. In Brazil several states and municipalities have already adopted a development strategy based on agglomerations of MEPs. This paper aims to show that the arrangement is a productive spot, identify the key factors that must exist within an arrangement for this reach a higher degree of success, considering the factors of cooperation, capital, learning, competitiveness and governance. It will also be presented a case study with the producers of vegetables and flowers Project Sao Tome, in the municipality of Aratuba in the Massif of Baturité with a view to identifying the stage where this arrangement is productive and analyzing the difficulties faced by those producers . Finally suggestions are given which can help address the bottlenecks identified in the arrangement.

description: We examine whether cubic non-linearities, allowed by symmetry in the elastic energy of a contact line, may result in a different universality class at depinning. Standard linear elasticity predicts a roughness exponent zeta=1/3 (one loop), zeta=0.39 (numerics) while experiments give zeta of about 0.5. Within functional RG we find that a non-local KPZ-type term is generated at depinning and grows under coarse graining. A fixed point with zeta=0.45 (one loop) is identified, showing that large enough cubic terms increase the roughness. This fixed point is unstable, revealing a rough strong-coupling phase. Experimental study of contact angles theta near pi/2, where cubic terms vanish in the energy, is suggested.

description: Non-local Thermodynamic Equilibrium (NLTE) calculations of hot white dwarf (WD) model atmospheres are the cornerstone of modern flux calibrations for the Hubble Space Telescope (HST) and for the CALSPEC database. These theoretical spectral energy distributions (SEDs) provide the relative flux vs. wavelength, and only the absolute flux level remains to be set by reconciling the measured absolute flux of Vega in the visible with the Midcourse Space Experiment (MSX) values for Sirius in the mid-IR. The most recent SEDs calculated by the \textsc{tlusty} and \textsc{tmap} NLTE model atmosphere codes for the primary WDs G191-B2B, GD153, and GD71 show improved agreement to 1\% from 1500~Å to 30~\micron, in comparison to the previous 1\% consistency only from 2000~Å to 5~\micron. These new NLTE models of hot WDs now provide consistent flux standards from the FUV to the mid-IR.

description: Gradient-based algorithms, popular strategies to optimization problems, are essential for many modern machine-learning techniques. Theoretically, extreme points of certain cost functions can be found iteratively along the directions of the gradient. The time required to calculating the gradient of $d$-dimensional problems is at a level of $\mathcal{O}(poly(d))$, which could be boosted by quantum techniques, benefiting the high-dimensional data processing, especially the modern machine-learning engineering with the number of optimized parameters being in billions. Here, we propose a quantum gradient algorithm for optimizing general polynomials with the dressed amplitude encoding, aiming at solving fast-convergence polynomials problems within both time and memory consumption in $\mathcal{O}(poly (\log{d}))$. Furthermore, numerical simulations are carried out to inspect the performance of this protocol by considering the noises or perturbations from initialization, operation and truncation. For the potential values in high-dimension optimizations, this quantum gradient algorithm is supposed to facilitate the polynomial-optimizations, being a subroutine for future practical quantum computer.

description: This paper reviews some of my work in experience-based computational sculpture, using a technique which I call Interactive 3D Printing, an amalgamation of generative art, livecoding, and sculpture. I3DP draws on a rich history of iterative revision and aesthetic refinement in the computational arts. This work foregrounds the time-based experience of digitally fabricating objects by describing them using only terms for time and rhythm (beats, beats-per-minute, duration, musical notes) following Paul Klee’s observation that “space itself is a temporal concept”. It explores the liminal state between finished/unfinished objects inside a manufacturing process by incorporating the sound of the manufacturing process into the experience of its products. I discuss how this work can be understood as both an improvised livecoding performance and a work of generative art where each iteration (or “instantiation”) has the potential to self-actualise and change over time according to the intrinsic nature of both computational and improvisational works of art.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: In this paper we present results on the disordered Holstein-Double Exchange model, explicitly in three dimension and `metallic' densities, obtained by using a recently developed Monte Carlo approach. Following up on our earlier paper, cond-mat/0406085, here we provide a detailed microscopic picture of the thermally driven metal-insulator transition (MIT) that arises close to the ferromagnet to paramagnet transition in this problem. This paper is focused mainly on the `diagnostics', clarifying the origin of the effective disorder that drives the MIT in this system. To that effect, we provide results on the thermal evolution of the distributions of (i) lattice distortions, (ii) the net `structural disorder' and (iii) the `hopping disorder' arising from spin randomness feeding back through the Hunds coupling. We suggest a phenomenology for the thermally driven MIT, viewing it as an `Anderson-Holstein' transition.

The critical exponent for nonlinear damped $σ$-evolution equations

Publisher: name: arXiv
Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)

description: In this paper, we derive suitable optimal $L^p-L^q$ decay estimates, $1\leq p\leq q\leq \infty$, for the solutions to the $σ$-evolution equation, $σ>1$, with structural damping and power nonlinearity $|u|^{1+α}$ or $|u_t|^{1+α}$, \[ u_{tt}+(-Δ)^σu +(-Δ)^θu_t=\begin{cases} |u|^{1+α}, \\ |u_t|^{1+α}, \end{cases}\] where $t\geq0$ and $x\in\mathbb{R}^n$. Using these estimates, we can solve the problem of finding the critical exponents for the two nonlinear problems above in the so-called non-effective case, $θ\in(σ/2,σ]$. This latter is more difficult than the effective case $θ\in[0,σ/2)$, since the asymptotic profile of the solution involves a diffusive component and an oscillating one. The novel idea in this paper consists in treating separately the two components to neglect the loss of decay rate created by the interplay of the two components. We deal with the oscillating component, by localizing the low frequencies, where oscillations appear, in the extended phase space. This strategy allows us to recover a quasi-scaling property which replaces the lack of homogeneity of the equation.

description: The formation of spherical polaron clusters is studied within the Fr$\ddot{o}$hlich polaron theory. In a dilute polaron gas, using the non-local statistical approach and the polaron pair interaction obtained within the Pekar strong coupling theory, the homogeneous phase results to be unstable toward the appearance of polaron clusters. The physical conditions of formation for the clusters are determined calculating the critical values of electron-phonon interaction for which bound states in the collective polaron potential develop. Finally the sequence in the filling of the states is found and the stability of the clusters is assessed.

description: In this paper we classify invariant noncommutative connections in the framework of the algebra of endomorphisms of a complex vector bundle. It has been proven previously that this noncommutative algebra generalizes in a natural way the ordinary geometry of connections. We use explicitely some geometric constructions usually introduced to classify ordinary invariant connections, and we expand them using algebraic objects coming from the noncommutative setting. The main result is that the classification can be performed using a ``reduced'' algebra, an associated differential calculus and a module over this algebra.

description: This paper proposes an art historical critical review of (re-)staging analog process-based art at the intersection of technology and ecology in digital spaces. It highlights contemporary artistic practices such as experience design and collaborative worldbuilding as strategies of (re-)staging and (re-)documenting process-based art in contemporary video game and social media platforms (par. 1-2). The paper analyzes the role of video games as spaces for cultural practice and protest (par. 3). The focus is put on earthworks and performance art and the process of their transformation from natural phenomena to digital matter (part. 4-5). Shing Yin Khor’s transfer of Robert Smithson’s earthwork icon Spiral Jetty (Great Salt Lake, Utah, 1970) into the digital landscape of the video game Animal Crossing. New Horizons in 2020 is looked at closely, as well as Khor’s digital (re-)performance of Marina Abramović’s The Artist is Present (MoMA, New York, 2010). I argue that the (re-)staging of ephemeral process-based art such as earthworks and performances represents an artistic strategy of research and knowledge transfer at the intersection of imagination and memory, which can be made useful for archival and curatorial practices – both in analog and digital spaces.

We show how N scalar fields may be described by N kinetic fluids (with maximally stiff equation of state) interacting with a non-dynamical potential (with vacuum equation of state). We split generic perturbations into adiabatic and entropic parts, and give the coupled first-order evolution equations on all scales, including energy and momentum exchange. We identify the non-adiabatic effects on large scales, and define adiabatic initial conditions in the presence of multiple fluids and fields.

description: The balloon-borne Compton Spectrometer and Imager (COSI) had a successful 46-day flight in 2016. The instrument is sensitive to photons in the energy range $0.2$-$5$ MeV. Compton telescopes have the advantage of a unique imaging response and provide the possibility of strong background suppression. With its high-purity germanium detectors, COSI can precisely map $γ$-ray line emission. The strongest persistent and diffuse $γ$-ray line signal is the 511 keV emission line from the annihilation of electrons with positrons from the direction of the Galactic centre. While many sources have been proposed to explain the amount of positrons, $\dot{N}_{\mathrm{e^+}} \sim 10^{50}\,\mathrm{e^+\,yr^{-1}}$, the true contributions remain unsolved. In this study, we aim at imaging the 511 keV sky with COSI and pursue a full-forward modelling approach, using a simulated and binned imaging response. For the strong instrumental background, we describe an empirical approach to take the balloon environment into account. We perform two alternative methods to describe the signal: Richardson-Lucy deconvolution, an iterative method towards the maximum likelihood solution, and model fitting with pre-defined emission templates. Consistently with both methods, we find a 511 keV bulge signal with a flux between $0.9$ and $3.1 \times 10^{-3}\,\mathrm{ph\,cm^{-2}\,s^{-1}}$, confirming earlier measurements, and also indications of more extended emission. The upper limit we find for the 511 keV disk, $< 4.3 \times 10^{-3}\,\mathrm{ph\,cm^{-2}\,s^{-1}}$, is consistent with previous detections. For large-scale emission with weak gradients, coded aperture mask instruments suffer from their inability to distinguish isotropic emission from instrumental background, while Compton-telescopes provide a clear imaging response, independent of the true emission.

description: The Hungarian artist Vera Molnar, living in Paris, is considered a pioneer in computer art. At first glance, her plotter drawings from the 1960s and 1970s seem to stand out as chaotic images, but upon closer inspection they let some structures appear. The series make visible the transformations resulting from her algorithmic instructions combined with a random generator, producing multiple configurations. The interest was to push the study of forms to disorder and discover structures within it. The computer images rising at the time were investigated by Georg Nees in his doctoral dissertation, supervised by philosopher Max Bense. The paper brings together Molnar’s early works and Nees’s information aesthetics, which analyzes the metric, statistical, and topological structures of computer images, in order to discuss their implications for philosophical aesthetics in relation to the complexity of computer graphics as openness to form processes.

description: DeepDream is a computer vision program designed to make associations starting from a given image; these associations are based on its training, that is its recognition “habits”. The aim of this article is to analyze DeepDream’s specific functioning as an example of non-human imaginative behavior endowed with its own visual style (par. 1). This claim is substantiated by a non-anthropocentric perspective on style (par. 2) and creativity (par. 3). Style is conceptualized as an encounter between different factors (such as function, form, context and materials) occurring within a problematic field; creativity, on the other hand, is referred to the systemic capacity of entering a process of self-organization resulting in an act of individuation.

Parasites at Work.

description: The paper considers the field of glitch art and aims to analyze it historically and theoretically. In the first section, the glitch is addressed in its general features, i.e., as a minor malfunction that calls into question the ordinary functioning of both technical and socio-political machines. Then (section 2), I sketch a history of the ways in which the glitch has circulated across different artistic media and genres. The third section draws attention to an often-overlooked aspect of glitching dynamics, i.e., the fact that the glitch differs logically and practically from the bug that generates it. While these three sections are also intended as a critical survey on the existing literature, the fourth section aims to outline an original proposal for an aesthetics of glitch art. Such account unfolds as an aesthetics of parasitism, where the bug plays the role of the parasite (the material and yet invisible element that perturbs the artwork’s digital code) and the glitch plays the role of the symptom (the artwork’s hyper-visible, disturbing phenomenal appearance).

La recherche du visage parfait dans le numérique.
Creators: name: Leone, Massimo
Publisher: name: Trópos
Year: 2023

description: The article provides a critical examination of the cultural semiotics of mathematics, recognizing it as a language rooted in human cognition. It posits that mathematics frequently transcends its role as a mere structural tool of reality, morphing instead into a form of biased rhetoric. This shift imbues various human domains, inherently unstructured and swayed by ideological biases, with a misleading sense of commensurability, precision, and accuracy. A key focus of the study is the mathematical measurement of the body, particularly the head and face. The practice of bodily measurements was pivotal in advancing ancient medicine into a modern science and practice. Nonetheless, these methods have progressively been appropriated as instruments of biopolitical control. The essay delves into the specific practice of “facial mensuration” originating in the Enlightenment era. This practice was based on thepremise that measuring heads, skulls, and faces could yield objective insights into beauty, intelligence, morality, and an individual’s position within a natural evolutionary hierarchy. However, a cultural semiotic analysis of this practice uncovers its use of facial mathematics as a tool for masking and objectifying racist prejudices. Importantly, the analysis highlights that the inherent biases do not lie in the measurements themselves but rather in the underlying decision to employ these measurements.

description: This paper delves into an examination of the relationship between images, materiality, and objects, employing diverse approaches to critically engage with this nexus. Drawing upon the phenomenology of images articulated by Husserl and Sartre, the study explores the transformative shifts and prominent historical paradigms shaping the conceptualization and interaction with images and their corresponding desires – spanning from idols to icons and artistic works. Expanding upon Benjamin’s thesis, it advances a framework to comprehend the evolving status of “technical” images through the concept of “cleavage” between the image’s support and the image-object, aligning this perspective with derealization theories that construe the proliferation of images as a loss of reality. Ultimately, the paper provides an interpretation of the distinctive phenomenon of digital images and their potential object status, contextualized within emerging practices, advocating for a stance in favor of digital materialism.

Ein Streifzug durch die Abstraktionsebenen digitaler Formen
Creators: name: Martin, Katharina D.
Publisher: name: Trópos
Year: 2023

description: The binary system as presented by Leibniz owes its metaphysical appeal to a mathematical universality which is also often incorrectly attributed to digital operationality. The article draws on Friedrich Kittler and Umberto Eco to remind us that digital functionality is based on the conjunction of the binary system and mathematical logic. Strictly speaking, digital machines are part of a complex information technology, based on translation processes and dependent on a code (Joseph Weizenbaum). However, this essay not only explains the underlying operational principle of digital machines, but also introduces digital forms (Yuk Hui) that are existentially linked to our discourses, our way of thinking, and our modes of behaviour. The article does not answer the ontological question of whether the binary/logical machines develop creatively and intellectually – a notion that Dieter Mersch clearly contradicts – but gives us a form-theoretical investigation that visualises digital productivity.

Algorithmic approach to diagrammatic expansions for real-frequency evaluation of susceptibility functions

description: We systematically generate the perturbative expansion for the two-particle spin susceptibility in the Feynman diagrammatic formalism and apply this expansion to a model system - the single-band Hubbard model on a square lattice. We make use of algorithmic Matsubara integration (AMI) [A. Taheridehkordi, S. H. Curnoe, and J. P. F. LeBlanc, Phys. Rev. B 99, 035120 (2019)] to analytically evaluate Matsubara frequency summations, allowing us to symbolically impose analytic continuation to the real frequency axis. We minimize our computational expense by applying graph invariant transformations [Amir Taheridehkordi, S. H. Curnoe, and J. P. F. LeBlanc, Phys. Rev. B 101, 125109 (2020)]. We highlight extensions of the random-phase approximation and T-matrix methods that, due to AMI, become tractable. We present results for weak interaction strength where the direct perturbative expansion is convergent, and verify our results on the Matsubara axis by comparison to other numerical methods. By examining the spin susceptibility as a function of real-frequency via an order-by-order expansion we can identify precisely what role higher order corrections play on spin susceptibility and demonstrate the utility and limitations of our approach.

Œuvres achéiropoïètes.
Creators: name: Chiurazzi, Gaetano
Publisher: name: Trópos
Year: 2023

description: Taking as a pretext the painting, exhibited in 1910 in Paris, that was signed by J.-R. Boronali but in fact painted by the donkey Lolo, this text aims to discuss the possibility that art can be made by non-human beings. The question is renewed today in the case of Artificial Intelligence, which also is supposed to paint and make art without human intervention. This strange coincidence of artistic production involving animals and Artificial Intelligence is then compared to the issue concerning acheiropoietic images, i.e. images that “have not been painted by human hand”, discussed during the Middle Ages. Like these icons, the works of animals and artificial intelligence enjoy an almost divine status, as they are believed not to have been made by any human being. The thesis supported here is that it is still the human being the one who, in any case, produces works of art, however mediated the process leading to the final product may be. Art is the work of the human, i.e. it is “made by human hand”.

description: The Energy Star label program to promote the diffusion of energy efficient home appliances is arguably the most significant government effort to reduce U.S. residential energy consumption. Program effectiveness requires that consumers are aware of the labeling scheme and also change their purchase decisions based on label information. This paper examines the factors associated with consumer awareness of the Energy Star label of recently purchased ‘white’ major appliances and the factors associated with the choice of Energy Star labeled appliances. The paper finds that household characteristics have a much stronger association with consumers awareness of labels than with the choice of Energy Star appliances. Renting the home, Hispanic ethnicity, being poor or near poor, and living in regions with lower ACEEE scores do, however, decrease the propensity for households to purchase Energy Star appliances. Eliminating these gaps in Energy Star appliance adoption would result in house electricity cost savings of $164 million per year and associated carbon emission reductions of about 1.1 million metric tons per year.
A Landscape called not and now : performing selected scenes from a play by Gertrude Stein
Creators: name: Arvidson, Heather
Publisher: name: University of British Columbia
Year: 2009

description: This report develops an interpretation of Gertrude Stein's theory that plays could be landscapes rather than narratives, and describes the project of producing part of Stein's "A Play Called Not and Now" as a landscape play. Over the course of a two-week workshop and a final performance on June 2, 2005 at UBC's Telus Studio Theatre, I directed a team of actors in an adaptation of scenes from the play. Informed by her theory, this collaborative project provided the opportunity to concretely work through Stein's idea of what was, in her time, a radically new kind of theatre. The staging was based on physical theatre exercises inspired loosely by Anne Bogart's Viewpoints. These provided a method for realizing Stein's sketch of a spatial theatre in which spectators can remain continuously present to the sounds, sights, lights and presences that surround them. The ensemble's movement and dynamic relationships created a physical landscape to fill the basic, elliptical structure of a play that Stein scripted in "A Play Called Not and Now." In this way, we took up Stein's invitation to collaboratively animate her script and pose it in relation to a physical composition, elucidating both text and theory in the process.
Ideal classes of three dimensional Artin-Schelter regular algebras

description: We determine the possible Hilbert functions of graded rank one torsion free modules over three dimensional Artin-Schelter regular algebras. It turns out that, as in the commutative case, they are related to Castelnuovo functions. From this we obtain an intrinsic proof that the space of torsion free rank one modules on a non-commutative projective plane is connected. A different proof of this fact, based on deformation theoretic methods and the known commutative case has recently been given by Nevins and Stafford. For the Weyl algebra it was proved by Wilson.

description: We develop a stochastic calculus that makes it easy to capture a variety of predictable transformations of semimartingales such as changes of variables, stochastic integrals, and their compositions. The framework offers a unified treatment of real-valued and complex-valued semimartingales. The proposed calculus is a blueprint for the derivation of new relationships among stochastic processes with specific examples provided below.

How Policy Affects Incentives and Contract Duration in Biomass Production

description: Policies such as Biomass Crop Assistance Program (BCAP) which aim to assist farmers with biomass production may act as a double-edged sword. On one hand, they lure farmers to adopt biomass production in the short term. On the other hand, they can’t be irresponsible for farmers’ abandonment of biomass production in the long run. The paper sharpens this idea in a principal-agent setting and argues that by offering a timely loyalty premium the agents’ take-and-run behavior can be mitigated. Moreover, the model shows that effort and investment in human capital are increasing in loyalty premium when agents decide to continue providing biomass after testing-water contract expires.
Finite Gauge Theory on Fuzzy CP^2

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We give a non-perturbative definition of U(n) gauge theory on fuzzy CP^2 as a multi-matrix model. The degrees of freedom are 8 hermitian matrices of finite size, 4 of which are tangential gauge fields and 4 are auxiliary variables. The model depends on a noncommutativity parameter 1/N, and reduces to the usual U(n) Yang-Mills action on the 4-dimensional classical CP^2 in the limit N -> \infty. We explicitly find the monopole solutions, and also certain U(2) instanton solutions for finite N. The quantization of the model is defined in terms of a path integral, which is manifestly finite. An alternative formulation with constraints is also given, and a scaling limit as R^4_θis discussed.

Region of the anomalous compression under Bondi-Hoyle accretion

description: We investigate the properties of an axisymmetric non-magnetized gas flow without angular momentum on a small compact object, in particular, on a Schwarzschild black hole in the supersonic region near the object; the velocity of the object itself is assumed to be low compared to the speed of sound at infinity. First of all, we see that the streamlines intersect (i.e., a caustic forms) on the symmetry axis at a certain distance $r_x$ from the center on the front side if the pressure gradient is neglected. The characteristic radial size of the region, in which the streamlines emerging from the sonic surface at an angle no larger than $θ_0$ to the axis intersect, is $Δr= r_xθ^2_0/3.$ To refine the flow structure in this region, we numerically compute the system in the adiabatic approximation without ignoring the pressure. We estimate the parameters of the inferred region with anomalously high matter temperature and density accompanied by anomalously high energy release.
