description: This short survey of recent work in tile self-assembly discusses the use of simulation to classify and separate the computational and expressive power of self-assembly models. The journey begins with the result that there is a single universal tile set that, with proper initialization and scaling, simulates any tile assembly system. This universal tile set exhibits something stronger than Turing universality: it captures the geometry and dynamics of any simulated system. From there we find that there is no such tile set in the noncooperative, or temperature 1, model, proving it weaker than the full tile assembly model. In the two-handed or hierarchal model, where large assemblies can bind together on one step, we encounter an infinite set, of infinite hierarchies, each with strictly increasing simulation power. Towards the end of our trip, we find one tile to rule them all: a single rotatable flipable polygonal tile that can simulate any tile assembly system. It seems this could be the beginning of a much longer journey, so directions for future work are suggested.

description: The most detailed published census data on occupations and industries from nine British censuses between 1841 and 2011 have been computerised, and original methods developed both to re-district them from constantly changing historical districts to the 380 Local Authority Districts reported on by the 2011 census and to re-classify them to the 20 ‘Sections’ of the 2007 Standard Industrial Classification. This large dataset is then used to reveal new insights into the long-run evolution of geographical unevenness in the British economy. Initial analysis reported here maps the total percentage in the service sector for 1841, 1931, 1991 and 2011, with original data for key sectors presented for 1841, 1931 and 1991. While counts for individual districts and ‘Sections’ must be used carefully, overall trends appear robust: the localities of Britain have not just been moving steadily towards economies dominated by the service sector, they have steadily been becoming more similar.
A Novel Progressive Image Scanning and Reconstruction Scheme based on Compressed Sensing and Linear Prediction

description: Compressed sensing (CS) is an innovative technique allowing to represent signals through a small number of their linear projections. In this paper we address the application of CS to the scenario of progressive acquisition of 2D visual signals in a line-by-line fashion. This is an important setting which encompasses diverse systems such as flatbed scanners and remote sensing imagers. The use of CS in such setting raises the problem of reconstructing a very high number of samples, as are contained in an image, from their linear projections. Conventional reconstruction algorithms, whose complexity is cubic in the number of samples, are computationally intractable. In this paper we develop an iterative reconstruction algorithm that reconstructs an image by iteratively estimating a row, and correlating adjacent rows by means of linear prediction. We develop suitable predictors and test the proposed algorithm in the context of flatbed scanners and remote sensing imaging systems. We show that this approach can significantly improve the results of separate reconstruction of each row, providing very good reconstruction quality with reasonable complexity.

I Racconti dell’Atelier dell’Errore fra disegno e performance

description: L’idea che la narrazione sia a pieno titolo un comportamento cognitivo e un’attitudine tipica della specie Homo sapiens e che il racconto di storie attraverso cui si svelano traumi e condizioni di disagio sia necessario e salutare non solo per chi narra ma anche per chi ascolta è ormai consolidata nelle scienze cognitive, nella psicoanalisi, nella teoria letteraria, nelle neuroscienze, nella ricerca medica e nella pratica clinica. Ma cosa accade quando non può essere la sola parola il veicolo espressivo di una narrazione? Quando il solo dire, che non è certo il primo né l’unico dei nostri tanti modi di rappresentarci il mondo, non ce la fa, e ha bisogno di affidarsi al corpo e allearsi con altre arti – per esempio quelle corporee del disegno e del teatro – per far uscire un magma di emozioni altrimenti inesprimibili? È quanto accade nell’Atelier dell’Errore nato nel 2002, un laboratorio creativo progettato all’artista visivo Luca Santiago Mora come servizio integrativo all’attività clinica della Neuropsichiatria Infantile di Reggio Emilia in cui adolescenti con gravi disabilità cognitive si raccontano attraverso il disegno. Il contributo intende proporsi come riflessione intorno a questa esperienza di espressione emozionale, con una particolare attenzione alle modalità in cui i ragazzi dell’Atelier e la loro guida hanno tradotto e rispazializzato il racconto delle loro passioni dai fogli del disegno alla scena teatrale.

Numerical study on a canonized Hamiltonian system representing reduced magnetohydrodynamics and its comparison with two-dimensional Euler system

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Introducing a Clebsch-like parameterization, we have formulated a canonical Hamiltonian system on a symplectic leaf of reduced magnetohydrodynamics. An interesting structure of the equations is in that the Lorentz-force, which is a quadratic nonlinear term in the conventional formulation, appears as a linear term -ΔQ, just representing the current density (Q is a Clebsch variable, and Δ is the two-dimensional Laplacian); omitting this term reduces the system into the two-dimensional Euler vorticity equation of a neutral fluid. A heuristic estimate shows that current sheets grow exponentially (even in a fully nonlinear regime) together with the action variable P that is conjugate to Q. By numerical simulation, the predicted behavior of the canonical variables, yielding exponential growth of current sheets, has been demonstrated.

description: Unambiguous identification of Majorana physics presents an outstanding problem whose solution could render topological quantum computing feasible. We develop a numerical approach to treat finite-size superconducting chains supporting Majorana fermions, which is based on iterative application of a two-site Bogoliubov transformation. We demonstrate the applicability of the method by studying a resonant level attached to the superconductor subject to external perturbations. In the topological phase, we show that the spectrum of a single resonant level allows to distinguish peak coming from Majorana physics from the Kondo resonance.

description: Population shrinkage has gained attention from academics and policymakers in recent years, due to the long-term implications the phenomenon has for public service delivery and the viability of urban and rural communities. We visualise the socio-temporal evolution of population shrinkage and growth, utilising a spatially rectified dataset containing population data from seven Census of Population covering the 1986–2016 period in the Republic of Ireland. Spatial changes in population distribution are visualised in a map that classifies small administrative units using a spatial typology distinguishing between those experiencing population growth or shrinkage, across the 30-year period. The temporal dimensions of these developments are considered in a sequence of inset maps that apply the same typology to identify the intercensal changes. Overall, the map facilitates the visual communication of long-run population trends, the identification of areas experiencing limited or no growth, and indicates the relative consistency of these trends over time.

description: Self-exciting point processes describe the manner in which every event facilitates the occurrence of succeeding events. By increasing excitability, the event occurrences start to exhibit bursts even in the absence of external stimuli. We revealed that the transition is uniquely determined by the average number of events added by a single event, $1-1/\sqrt{2} \approx 0.2929$, independently of the temporal excitation profile. We further extended the theory to multi-dimensional processes, to be able to incite or inhibit bursting in networks of agents.

Explaining the Rise of East Asian Multinationals: State-Industry Links, a Stages Model of Structural Change, and Japan as a Precedent Setter

description: This paper examines state‐ and industry- linkages in the course of the rise of multinationals in emerging markets by drawing on East Asian experiences. Multinationals are both a creature and an instrument of industrial structural change that characterizes the process of economic development. In order for emerging markets to initiate and sustain catch‐up industrialization, they need government involvement to spark a takeoff and nurture their own multinationals so that they can exploit overseas business opportunities at each stage of structural change. Hence, a stages model of growth with five tiers of industry is adopted as an overall analytic. In this regard, Japan set two precedents in (i) transplanting low‐wage production abroad via outward FDI as a catalyst for industrial upgrading at home (i.e., what may be called “comparative advantage recycling in low-wage production”), and (ii) combining its resource-seeking FDI with economic cooperation in emerging host economies (i.e., development‐ oriented resources diplomacy). The precedent of low-wage production transplantation was followed by the NIEs and has just begun to be replicated by China. The precedent of FDI‐cum-economic cooperation was likewise followed by South Korea and Taiwan and is currently most actively repeated by China in its efforts to secure overseas minerals and fuels.

Then suitable quadrature rules are devised and order conditions of algebraic type are derived. Theoretical findings are validated by means of numerical experiments and the effectiveness of the proposed approach is illustrated by means of comparisons with other standard methods.

description: This is a preliminary theoretical discussion on the computational requirements of the state of the art smoothed particle hydrodynamics (SPH) from the optics of pattern recognition and artificial intelligence. It is pointed out in the present paper that, when including anisotropy detection to improve resolution on shock layer, SPH is a very peculiar case of unsupervised machine learning. On the other hand, the free particle nature of SPH opens an opportunity for artificial intelligence to study particles as agents acting in a collaborative framework in which the timed outcomes of a fluid simulation forms a large knowledge base, which might be very attractive in computational astrophysics phenomenological problems like self-propagating star formation.

We present here studies on the vacuum stability and color/charge breaking minima in the CMSSM and R parity violating minima in a B-L extended MSSM.

Does their instrumental effectiveness stand on the rock of secure concepts or the sand of unresolved fundamentals? Does measuring a quantum system probe, or even create, reality, or merely change belief? Must relativity and quantum theory just co-exist or might we find a new theory which unifies the two? To bring such questions into sharper focus, we convened a conference on Quantum Physics and the Nature of Reality. Some issues remain as controversial as ever, but some are being nudged by theory's secret weapon of experiment.

description: We propose a quantum fitting scheme to estimate the magnetic field gradient with $N$-atom spins preparing in W state, which attains the Heisenberg-scaling accuracy. Our scheme combines the quantum multi-parameter estimation and the least square linear fitting method to achieve the quantum Cramér-Rao bound (QCRB). We show that the estimated quantity achieves the Heisenberg-scaling accuracy. In single parameter estimation with assumption that the magnetic field is strictly linear, two optimal measurements can achieve the identical Heisenberg-scaling accuracy. Proper interpretation of the super-Heisenberg-scaling accuracy is presented. The scheme of quantum metrology combined with data fitting provides a new method in fast high precision measurements.

description: Recently, it was argued that the thermal deconfinement transition in pure Yang-Mills theory is continuously connected to a quantum phase transition in softly-broken N=1 SYM theory on R^3 x S^1. The transition is semiclassically calculable at small S^1 size L, occurs as the soft mass m_soft and L vary, and is driven by a competition between perturbative effects and nonperturbative topological molecules. These are correlated instanton--anti-instanton tunneling events, whose constituents are monopole-instantons "bound" by attractive long-range forces. The mechanism driving the transition is universal for all simple gauge groups, with or without a center, such as SU(N) or G_2. Here, we consider theories with fundamental quarks. We examine the role topological objects play in determining the fate of the (exact or approximate) center-symmetry in SU(2) SQCD, with or without soft-breaking terms. In theories whose large-m_soft limit is thermal nonsupersymmetric QCD with massive quarks, we find a crossover of the Polyakov loop, from approximately center-symmetric at small 1/L to maximally center-broken at larger 1/L, as seen in lattice thermal QCD with massive quarks and T=1/L. We argue that in all calculable cases, including SQCD with exact center symmetry, quarks deform instanton-monopoles by their quantum fluctuations and do not contribute to their binding. The semiclassical approximation and the molecular picture of the vacuum fail, upon decreasing the quark mass, precisely when quarks would begin mediating a long-range attractive force between monopole-instantons, calling for a dual description of the resulting strong-coupling theory.

How to Obtain Computational Completeness in P Systems with One Catalyst

Year: 2013

description: Whether P systems with only one catalyst can already be computationally complete, is still an open problem. Here we establish computational completeness by using specific variants of additional control mechanisms. At each step using only multiset rewriting rules from one set of a finite number of sets of multiset rewriting rules allows for obtaining computational completeness with one catalyst and only one membrane. If the targets are used for choosing the multiset of rules to be applied, for getting computational completeness with only one catalyst more than one membrane is needed. If the available sets of rules change periodically with time, computational completeness can be obtained with one catalyst in one membrane. Moreover, we also improve existing computational completeness results for P systems with mobile catalysts and for P systems with membrane creation.

description: We revisit the story of technology adoption and diffusion in the Meiji-era cotton spinning industry in Japan, the study of which was pioneered by Gary Saxonhouse in an article published in JEH exactly 40 years ago. Using a novel data set and modern methodology, we argue that both the ease with which the best technology was diffused and the role of “slavish imitation” in this process may have been overstated. We find an important role played by market competition, including asset reallocation. Our analyses provide researchers with even richer insights into general questions of innovation, technology diffusion, and economic growth.

description: In this paper we review the production of primordial black holes (PBHs) during preheating after a chaotic inflationary model. All relevant equations of motion are solved numerically in a modified version of HLattice, and we then calculate the mass variance to determine structure formation during preheating. It is found that production of PBHs can be a generic result of the model, even though the results seem to be sensitive to the values of the smoothing scale. We consider a constraint for overproduction of PBHs that could uncover some stress between inflation-preheating models and observations.

description: We count Higgs "phase" BPS states of general non-Abelian quiver, possibly with loops, by mapping the problem to its Abelian, or toric, counterpart and imposing Weyl invariance later. Precise Higgs index computation is particularly important for quivers with superpotentials; the Coulomb "phase" index is recently shown to miss important BPS states, dubbed intrinsic Higgs states or quiver invariants. We demonstrate how the refined Higgs index is naturally decomposed to a sum over partitions of the charge. We conjecture, and show in simple cases, that this decomposition expresses the Higgs index as a sum over a set of partition-induced Abelian quivers of the same total charge but generically of smaller rank. Unlike the previous approach inspired by a similar decomposition of the Coulomb index, our formulae compute the quiver invariants directly, and thus offer a self-complete routine for counting BPS states.

description: Dynamics of clumps within a magnetized advection dominated accretion flow is investigated by solving the collisionless Boltzmann equation and considering the drag force due to the relative velocity between the clumps and the gas. Toroidal component of the magnetic field is assumed to be dominant. Dynamical properties of the hot gaseous component such as the radial and the rotational velocities are affected by the magnetic effects, and so, drag force varies depending on the strength of magnetic field and the velocity dispersion of the clumps is then modified significantly. We show that when magnetic pressure is less than the gas pressure, the root of the averaged radial velocity square of the clumps decreases at the inner parts of the hot flow and increases slightly at its outer edge.

O objetivo deste artigo é investigar de que modo o tráfico de meninas e mulheres na Amazônia é ficcionalizado, tendo por base teórica as categorias Necropolítica (Mbembe, 2018); Homo sacer (Agamben, 2010) e Capitalismo gore (Triana Valencia, 2010). Como resultado preliminar de um estudo mais detalhado sobre romances contemporâneos brasileiros, tem-se que o romance estudado, problematiza a vida a partir do contexto da política da morte, denominada necropolítica (Mbembe, 2018), seja pela representação estética do remanescente colonial da escravidão; seja pela emergência de mercados criminosos que florescem em meio aos grupos submetidos a condições mortíferas.O artigo propõe uma leitura do romance brasileiro Pssica (2015), de Edyr Augusto partindo da premissa de que a narrativa ficcionaliza o problema das rotas de exploração sexual na Amazônia Brasileira.

description: We suggest an explanation of a sharp increase in the abundance of cosmogenic radiocarbon found in tree rings dated AD 775. The increase could originate from high-energy irradiation of the atmosphere by a galactic gamma-ray burst. We argue that, unlike a cosmic ray event, a gamma-ray burst does not necessarily result in a substantial increase in long-lived 10Be atmospheric production. At the same time, the 36Cl nuclide would be generated in the amounts detectable in the corresponding ice core samples from Greenland and Antarctica. These peculiar features allow experimental discrimination of nuclide effects caused by gamma-ray bursts and by powerful proton events.
Topology and Non-Deterministic Polynomial Time Computation : Avoidance of The Misbehaviour of Hub-Free Diagrams and Consequences

description: To study groups with small Dehn's function, Olshanskii and Sapir developed a new invariant of bipartite chords diagrams and applied it to hub-free realization of S-machines. In this paper we consider this new invariant together with groups constructed from S-machines containing the hub relation. The idea is to study the links between the topology of the asymptotic cones and polynomial time computations. Indeed it is known that the topology of such metric space depends on diagrams without hubs that do not correspond to the computations of the considered S-machine. This work gives sufficient conditions that avoid this misbehaviour, but as we shall see the method has a significant drawback.

"La grammatica della fantasia" arriva in Brasile: problemi e difficoltà nella prima traduzione in lingua portoghese di Gianni Rodari
Creators: name: Alberani, Elisa

Year: 2020

description: La pubblicazione dell’opera La Grammatica della Fantasia avviene, in Italia, nel 1973 e sarà la prima opera di Gianni Rodari ad essere tradotta e pubblicata in Brasile, nel 1982. Gli anni ’80 in Brasile rappresentano un periodo peculiare per la letteratura per l’infanzia e la pubblicazione, in questi anni, dell’opera di Rodari non è casuale, ma rientra in un progetto educativo specifico. La Grammatica è un’opera pedagogica, didattica, e, al contempo, metalinguistica, un aspetto, quest’ultimo, che ha portato a non poche difficoltà nella resa traduttiva in lingua portoghese. Scegliendo un approccio straniante, con pochissimi elementi addomesticanti, la traduzione brasiliana non risulta di facile lettura: essendo un libro pensato per un pubblico sia di adulti che di giovani, ci si interroga se le scelte traduttive effettuate abbiano influito sul tipo di ricezione e se abbiano altresì influenzato la pubblicazione delle altre opere di Rodari in Brasile, che a parte una sola eccezione, avviene quasi vent’anni dopo, già nel nuovo secolo.

Goal-Oriented Setup and Usage of Custom-Tailored Software Cockpits
Creators: name: Heidrich, Jens

Year: 2014
Subjects: subject: Software Engineering (cs.SE)

description: Software Cockpits, also known as Software Project Control Centers, support the management and controlling of software and system development projects and provide means for quantitative measurement-based project control. Currently, many companies are developing simple control dashboards that are mainly based on Spreadsheet applications. Alternatively, they use solutions providing a fixed set of project control functionality that cannot be sufficiently customized to their specific needs and goals. Specula is a systematic approach for defining reusable, customizable control components and instantiate them according to different organizational goals and characteristics based on the Quality Improvement Paradigm (QIP) and GQM. This article gives an overview of the Specula approach, including the basic conceptual model, goal-oriented measurement, and the composition of control components based on explicitly stated measurement goals. Related approaches are discussed and the use of Specula as part of industrial case studies is described.

description: Compressed sensing (CS) is an innovative technique allowing to represent signals through a small number of their linear projections. Hence, CS can be thought of as a natural candidate for acquisition of multidimensional signals, as the amount of data acquired and processed by conventional sensors could create problems in terms of computational complexity. In this paper, we propose a framework for the acquisition and reconstruction of multidimensional correlated signals. The approach is general and can be applied to D dimensional signals, even if the algorithms we propose to practically implement such architectures apply to 2-D and 3-D signals. The proposed architectures employ iterative local signal reconstruction based on a hybrid transform/prediction correlation model, coupled with a proper initialization strategy.
La conquista del diritto alla differenza: uno sguardo alla letteratura brasiliana per l'infanzia

description: La letteratura brasiliana per l’infanzia si è fondata, nella sua evoluzione storica, su una sostanziale marginalizzazione dei personaggi di pelle nera. Per buona parte del ‘900, anche in conseguenza del lungo passato schiavista, le storie non fanno altro che evidenziare la condizione subalterna degli afrodiscendenti mediante rappresentazioni stereotipate che li vedono pressoché muti e sempre ai limiti di ciò che è considerato accettabile o desiderabile (sia dal punto di vista sociale che estetico). Tra la fine degli anni ’70 e l’inizio degli anni ’80, grazie all’azione sempre più forte dei movimenti di rivendicazione sociale e razziale, si manifestano i primi accenni di una produzione letteraria impegnata nel superamento delle discriminazioni etnico-razziali. Tuttavia, il punto di svolta arriva solo con l’inizio del nuovo millennio: la legge 10.693/03, che rende obbligatorio l’insegnamento della storia della cultura afro-brasiliana e africana all’interno degli istituti scolastici pubblici e privati, rappresenta un’autentica rottura con la “tradizione del preconcetto” stimolando la pubblicazione di opere che guidano bambine e bambini neri verso l’auto-accettazione di sé e delle radici africane. Tra i testi pubblicati sulla scia delle nuove politiche educative, Amanhecer Esmeralda di Ferréz rappresenta un esempio originale poiché, forse in maniera più incisiva di altre opere destinate ai giovani lettori, ripensa il diritto all’educazione includendovi il diritto alla differenza.

Lithium incorporation at the MoS2/graphene interface: an ab initio investigation

description: Based on ab initio calculations, we examine the incorporation of Li atoms in the MoS2/graphene interface. We find that the intercalated Li atoms are energetically more stable than Li atoms adsorbed on the MoS2 surface. The intercalated atoms interact with both graphene sheet and MoS2 layer, increasing the Li binding energies. However, the equilibrium geometries are ruled by the MoS2 layer, where the intercalated Li atoms lie on the top (Li_T) and hollow (Li_H) sites of the MoS2 layer. We calculate the Li diffusion barriers, along the Li_T -> Li_H diffusion path, where we find similar energy barriers compared with that obtained for Li adatoms on the MoS2 surface. Our results allow us to infer that the Li storage capacity increases at MoS2/G interfaces, in comparison with Li adatoms on the MoS2 surface, however, with no reduction on the mobility of the intercalated Li atoms. Those properties are interesting/useful to the development of Li batteries based on MoS2.

description: Al buzón de Litoral lleva asomándose durante sus casi cien años de historia un abundantísimo material. En el principio de todo fue la carta fundacional, y desde el renacer de la publicación en 1968 de la mano de José María Amado hasta la actualidad con Lorenzo Saval como director, hemos catalogado y acaso ordenado una multiplicidad de corresponsales y letras manuscritas, de material epistolar y documentos personales —una caligrafía que llega en ocasiones a la consumación artística—, de los autores y artistas que por sus páginas han pasado. Una ojeada a la nómina de sus colaboradores es un recorrido completo por todo el panorama de la poesía, la música, la pintura y la tipografía españolas contemporáneas. Este trabajo es el segundo de una serie dedicada al mismo tema.

description: The protection of privacy of individual-level information in genome-wide association study (GWAS) databases has been a major concern of researchers following the publication of "an attack" on GWAS data by Homer et al. (2008) Traditional statistical methods for confidentiality and privacy protection of statistical databases do not scale well to deal with GWAS data, especially in terms of guarantees regarding protection from linkage to external information. The more recent concept of differential privacy, introduced by the cryptographic community, is an approach that provides a rigorous definition of privacy with meaningful privacy guarantees in the presence of arbitrary external information, although the guarantees may come at a serious price in terms of data utility. Building on such notions, Uhler et al. (2013) proposed new methods to release aggregate GWAS data without compromising an individual's privacy. We extend the methods developed in Uhler et al. (2013) for releasing differentially-private $χ^2$-statistics by allowing for arbitrary number of cases and controls, and for releasing differentially-private allelic test statistics. We also provide a new interpretation by assuming the controls' data are known, which is a realistic assumption because some GWAS use publicly available data as controls. We assess the performance of the proposed methods through a risk-utility analysis on a real data set consisting of DNA samples collected by the Wellcome Trust Case Control Consortium and compare the methods with the differentially-private release mechanism proposed by Johnson and Shmatikov (2013).
