description: In contrast with the fast solar wind, that originates in coronal holes, the source of the slow solar wind is still debated. Often intermittent and enriched with low FIP elements -- akin to what is observed in closed coronal loops -- the slow wind could form in bursty events nearby helmet streamers. Slow winds also exhibit density perturbations which have been shown to be periodic and could be associated with flux ropes ejected from the tip of helmet streamers, as shown recently by the WISPR white light imager onboard Parker Solar Probe (PSP). In this work, we propose that the main mechanism controlling the release of flux ropes is a flow-modified tearing mode at the heliospheric current sheet (HCS). We use MHD simulations of the solar wind and corona to reproduce realistic configurations and outflows surrounding the HCS. We find that this process is able to explain long ($\sim 10-20$h) and short ($\sim 1-2$h) timescales of density structures observed in the slow solar wind. This study also sheds new light on the structure, topology and composition of the slow solar wind, and could be, in the near future, compared with white light and in situ PSP observations.

description: This piece of work was carried out objectifying to adjust the time series models to the series of price indexes for the consumer ( PIC ) of Lavras MG. It aimed at verifying the occurrence of differences in trend as for the period which preceeded, as well as for the one which succeeded the Plano Real, and if there was a simple linear trend along with Plano Real ( 1994-1999 ) as well as if any seasonality occurred. It also objectified to comparing the series of both Lavras and the Federal District. It was verified that there was no trend along the whole series, nor there was any seasonality, notwithstanding the fact that a level change occurred, which was characterized as an intervention, rather than a trend. It was necessary to fit a model featuring an intervention for a better model adjustment and forecast. The parameters of the model which featured interventions were estimated and those coincided with the periods of governmental interventios in the Brazilian economy. The adjustment of a AR (1) model with intervention, proved to be more efficient than the one which would not consider the intervention in the forecast of PIC from May to December, 1999. To Brasília, the model fitted was an AR (2) with a permanent gradual intervention on the time 168 and a permanent sudden intervention on time 266 which correspond to two months, respectively the one following the introduction of Plano Cruzado and the other one, to the exact time when Plano Real was implanted. As for the period from August 1992 to December 1998, the series of both Lavras and Brasília are considered as being equal.
Il camouflage nel campo allargato. Variazioni su Disruptive Pattern Material e Dazzle Painting nella cultura visiva contemporanea

description: The First World War was the scenario that led to the invention and systematic use of military camouflage techniques. Between them, the two fundamental modes of static or pictorial camouflage: mimetic, known as Disruptive Pattern Material, and the naval, called Dazzle Painting. Avantgarde artists contributed to their birth. Immediately, there was the transfer of these techniques to the civilian sphere, revealing that its essentially practical essence did not prevent the exploitation of its aesthetic potential by contemporary visual culture. Throughout the twentieth and twenty-first centuries the fields of art, architecture and design continue importing and exploiting the strategies of these two types of military camouflage. This article analyzes the artistic potential of static military camouflage devised during World War I and its impact on the setting of an expanded notion of camouflage. If the camouflage was in its origins and early history a form of disclosure of modern art on a global scale, the use of DPM and Dazzle by contemporary artists, is a form of dissemination of military camouflage to civil level. We explore a double investment produced by military camouflage: providing avantgarde art with a practical sense, and providing camouflage with an aesthetic sense

description: Relativistic tidal equations are formulated with respect to the rest frame of a central gravitational source and their solutions are studied. The existence of certain relativistic critical tidal currents are thereby elucidated. Specifically, observers that are spatially at rest in the exterior Kerr spacetime are considered in detail; in effect, these fiducial observers define the rest frame of the Kerr source. The general tidal equations for the free motion of test particles are worked out with respect to the Kerr background. The analytic solutions of these equations are investigated and the existence of a tidal acceleration mechanism is emphasized.

description: During World War I, in response to substantial advancements in wartime surveillance, it became a common practice to rely on “vision specialists” to devise effective methods of fooling the enemy (tromper l’ennemi). These methods, collectively referred to now as camouflage, were designed by so-called camoufleurs, men who in civilian life had been trained as artists, graphic designers, architects, and theatre scenographers. Among the techniques they employed (for both ground and ship camouflage) were perspective-based spatial distortions, of the sort that are also frequently used in theatrical set design, trompe l’oeil paintings, and wildlife displays (called habitat dioramas). This paper describes these methods, explains how they were intended to work, and discusses their effectiveness.

description: In this letter, we investigate the detailed epidemic spreading process in scale-free networks with links' weights that denote familiarity between two individuals and find that spreading velocity reaches a peak quickly then decays in a power-law form. Numerical study exhibits that the nodes with larger strength is preferential to be infected, but the hierarchical dynamics are not clearly found, which is different from the well-known result in unweighed network case. In addition, also by numerical study, we demonstrate that larger dispersion of weight of networks results in slower spreading, which indicates that epidemic spreads more quickly on unweighted scale-free networks than on weighted scale-free networks with the same condition.

description: Given that the fast transformations occurred in national and international scenery point out to a necessity of gain of efficiency to increase in competitiveness to the firms, the environment which into they are and into they develop, assume a vital importance as been the supporter foundation of this development. For this environment can be understood as the process of space concentration of many correlative segments of a production chain, also called as clusterization process, which this special conformation gives to the firms special conditions to develops the superior competitive advantages than the others firms isolated. In this sense, this paper aim to arise how occurs the process of conformation of a big cluster, culminating in satisfaction of ten basic conditions described by Zaccarelli (1995), that gives to firms into them a advantageous competitive position in market. As the subject of study was focused on Bastos’ Eggs’ Agribusiness Chain which it been highly competitive in the national market of this product.

description: Charged stars have the potential of becoming charged black holes or even naked singularities. It is presented a set of numerical solutions of the Tolman-Oppenheimer-Volkov equations that represents spherical charged compact stars in hydrostatic equilibrium. The stellar models obtained are evolved forward in time integrating the Einstein-Maxwell field equations. It is assumed an equation of state of a neutron gas at zero temperature. The charge distribution is taken as been proportional to the rest mass density distribution. The set of solutions present an unstable branch, even with charge to mass ratios arbitrarily close to the extremum case. It is performed a direct check of the stability of the solutions under strong perturbations, and for different values of the charge to mass ratio. The stars that are in the stable branch oscillates and do not collapse, while models in the unstable branch collapse directly to form black holes. Stars with a charge greater or equal than the extreme value explode. When a charged star is suddenly discharged, it don't necessarily collapse to form a black hole. A non-linear effect that gives rise to the formation of an external shell of matter (see Ghezzi and Letelier 2005), is negligible in the present simulations. The results are in agreement with the third law of black hole thermodynamics and with the cosmic censorship conjecture.

Straightforward electrical resistance measurements of the interferometers give continuous read-out of the states, allowing us to construct the energy spectrum of the quantum circuit. The probe is estimated to be more precise and faster than previous methods, and can measure the local phase difference in a wide range of superconducting circuits.

description: This article wants to investigate the logic of mimicry and their communicative function in animal life adopting an aesthetical perspective. The relationship between appearance and not-appearance, between the act of making itself visible and the act of disguising itself, is investigated starting from the morphological thought of the Swiss biologist Adolf Portmann, in a continuous dialogue with great thinkers of past and actual time – Johann Wolfgang Goethe, Hannah Arendt and Roger Caillois – and with the artistic illustrations of the American painter Abbott Thayer, concerned with the laws of color camouflage. This productive relationship among biology, aesthetics and artistic practice allows us to show that the sphere of the skin, far from being "superficial" and meaningless, is the privileged point of view for a true semiotics of the visible.

description: The process of organizational change constitutes a highly complex theme due to the a host of both internal and external organizational factors that may cause changes to be either facilitated or restricted. Such process, which may come as the result of a previuos planning or otherwise will also feature a varied amplitude which enables it to result in either incremented changes, when comprising but a few organizational features or strategical, if a large number of such components get reached by the process. Using these as a starting point we aimed at learning, simulating and analizing in a comparative way, the main changes in family agro-business production units in two distinct locations in the town of Pato Branco PR, which have shown to be contrastive concerning general development and the exploitation of agriculture. A qualitative survey was employed, having the non-structured survey as research technic. Twelve typical agriculturists from each location, along with three rural extension technicians from Pato Branco were interviewed. In order to reconstruct and learn the changes a processual, contextual and historic perspective was adopted. In order to proceed as for the analysis, the changes were considered as having occurred within certain strategical periods. The five most representative strategical periods for the production units in each location were identified and it was verified that the local natural and social-economical conditions did represent relevant enabling factors for the huge contrasts in development between both locations. In spite of such contrast, most of the changes implemented by the studied producers are of incremental nature. Such changes are not usually planned for they occur as these agriculturists’ reactions to unforeseen new administrative situations.

description: Animal camouflage is said to be a mode of being negative, implying a setback visibility. On the contrary, we try here to restore all its aesthetic positivity considering the singularity of extremely varied forms it produces. It soon becomes apparent that the camouflage forces us to question the privilege of individuality and traditional drawdown on singularity. The disruptive camouflage, especially, that crushes the individual formal unity provides the argument in favor of an individuation with the environment, and more with the world: the animal camoufleur disappears under only an individual visibility; it appears on the contrary in all its pre-individual splendor when it involves with environment components to make them the most expressive.

description: A spreadsheet featuring production costs for coffee in different productivity ranges is presented in this study. The survey is based on the theory of costs and the study location was the southern region of the state of Minas Gerais, where data on 48 coffee production units were gathered during the 1998/99 harvest. Taking the economical indexes resulting from research into consideration, one may infer that expenses on variable resources represent the greater portion of the final cost of coffee. The items which affected production costs the most were crop formation, in the case of unvariable costs, and the expenses on labor, especially the seasonal kind. It was also concluded that coffee culture belongs to the scale-economy kind and , as a whole, the 1998/99 coffee harvest ended up economically profittable.

description: This piece of work objectified a historical analysis on the introduction and the widespread of coffee in the southern region of Minas Gerais. Considered as objects of historygraphic study were literary works, documents, journalistic, memorialistic, biographic, documental and didactic oriented texts. Yet another method used was the quantitative one, besides orally reported pieces of historical nature as well as life history which completed the official documentation. Our empiric investigation object was the southern side of Minas Gerais, the study’s theme being the historic development of coffee in such region. The widespread of coffee in the region caused the arisal of a new landscape profile- the coffee landscape. Self-supporting farms arised on sites formerly covered with untouched vegetation. It also caused many towns to expand, and railroads were multiplied substituting for the trails on which jack-asses were predominant.The first coffee cultures in the region were settled in Aiuruoca, Jacuí and Baependi, by the Sapucaí and Grande rivers valley in the late 1700’s, by the troopers which made the the limk between the south of Minas Gerais and the state of Rio de Janeiro. We inferred that the greatest barrier against the expansion of coffee in the south of Minas was the difficulties concerning transportation. The means of communication were then precarious and the distances to be covered were too long. Up until the end of the 19th century both production and exportation were only modest due to rival producing areas which were closer to the embarkation harbours.With the beginning of the 20th century came a new production dynamism, due to the railroads. It has been 200 years of coffee culture in the south of Minas Gerais, the greatest justification for the denomination “traditional coffee producing region.”

 The male from Vietnam, morphologically determined as R. luctus, showed a karyotype with a diploid chromosome number of 2 n = 32 and an autosomal fundamental number of FNa = 60. The karyotype consisted of 15 meta- to submetacentric autosomal pairs ranging from large to small, a large metacentric X chromosome and a large acrocentric Y chromosome (Fig. 1). C-banding revealed heterochromatin at all centromeres, in the proximal half of the short arm of the X chromosome, and in the Y chromosome with exception to the very proximal part (Fig. 2A). The secondary constriction in the short arm of chromosomal pair 8 (homologous to MMY21 and AST10) was proven to be the single site of Nucleolus Organizer Region (NOR) by silver-staining (Fig. 2B). The mean number of active NORs per cell was 1.7 (20 cells analyzed).
 The G-banding pattern of autosomal pairs was found to be similar to R. luctoides (Volleth et al., 2015). The identical arm composition of autosomes as in R. luctoides was confirmed by the results of whole chromosome painting with probes from A. stoliczkanus (AST), complemented with some probes from M. myotis (MMY3/4 and MMY8 for pair 1). The hybridization results are summarized on the karyotype (Fig. 1). Painting probes from biarmed AST autosomes hybridized to two different pairs each (examples in Fig. 3A and 3D).

description: Extreme pressure strongly affects the superconducting properties of ``simple'' elemental metals, like Li, K and Al. Pressure induces superconductivity in Li (as high as 17 K), while suppressing it in Al. We report first-principles investigations of the superconducting properties of dense Li, K and Al based on a recently proposed, parameter-free, method. Our results show an unprecedented agreement with experiments, assess the predictive power of the method over a wide range of densities and electron-phonon couplings, and provide predictions for K, where no experiments exist so far. More importantly, our results help uncovering the physics of the different behaviors of Li and Al in terms of phonon softening and Fermi surface nesting in Li.

description: In this paper, we introduce the notion of a noncommutative Poisson bialgebra, and establish the equivalence between matched pairs, Manin triples and noncommutative Poisson bialgebras. Using quasi-representations and the corresponding cohomology theory of noncommutative Poisson algebras, we study coboundary noncommutative Poisson bialgebras which leads to the introduction of the Poisson Yang-Baxter equation. A skew-symmetric solution of the Poisson Yang-Baxter equation naturally gives a (coboundary) noncommutative Poisson bialgebra. Rota-Baxter operators, more generally O-operators on noncommutative Poisson algebras, and noncommutative pre-Poisson algebras are introduced, by which we construct skew-symmetric solutions of the Poisson Yang-Baxter equation in some special noncommutative Poisson algebras obtained from these structures.

description: Combinatorial rigidity theory seeks to describe the rigidity or flexibility of bar-joint frameworks in R^d in terms of the structure of the underlying graph G. The goal of this article is to broaden the foundations of combinatorial rigidity theory by replacing G with an arbitrary representable matroid M. The ideas of rigidity independence and parallel independence, as well as Laman's and Recski's combinatorial characterizations of 2-dimensional rigidity for graphs, can naturally be extended to this winder setting. As we explain, many of these fundamental concepts really depend only on the matroid associated with G (or its Tutte polynomial) and have little to do with the special nature of graphic matroids or the field R. Our main result is a "nesting theorem" relating the various kinds of independence. Immediate corollaries include generalizations of Laman's Theorem, as well as the equality of 2-rigidity and 2-parallel independence. A key tool in our study is the space of photos of M, a natural algebraic variety whose irreducibility is closely related to the notions of rigidity independence and parallel independence. The number of points on this variety, when working over a finite field, turns out to be an interesting Tutte polynomial evaluation.

Single qubit measurements with an asymmetric single-electron transistor

description: We investigate qubit measurements using a single electron transistor (SET). Applying the Schrödinger equation to the entire system we find that an asymmetric SET is considerably more efficient than a symmetric SET. The asymmetric SET becomes close to an ideal detector in the large asymmetry limit. We also compared the SET detector with a point-contact detector. This comparison allows us to illuminate the relation between information gain in the measurement process and the decoherence generated by these measurement devices.

description: We analyze the existence and stability of localized solutions in the one-dimensional discrete nonlinear Schrödinger (DNLS) equation with a combination of competing self-focusing cubic and defocusing quintic onsite nonlinearities. We produce a stability diagram for different families of soliton solutions, that suggests the (co)existence of infinitely many branches of stable localized solutions. Bifurcations which occur with the increase of the coupling constant are studied in a numerical form. A variational approximation is developed for accurate prediction of the most fundamental and next-order solitons together with their bifurcations. Salient properties of the model, which distinguish it from the well-known cubic DNLS equation, are the existence of two different types of symmetric solitons and stable asymmetric soliton solutions that are found in narrow regions of the parameter space. The asymmetric solutions appear from and disappear back into the symmetric ones via loops of forward and backward pitchfork bifurcations.

description: Organic farming may be seen as an alternative approach to agriculture that tries to integrate environmental concerns in management practices. By means of DEA, in this work we calculate and compare the efficiency of two samples of conventional and organic vineyards, from two different perspectives: in the first instance, the relationship between inputs and outputs is considered, exclusively, that is, the private efficiency; in the second instance, social efficiency is calculated, and the environmental impacts arising from the activity are also included. The comparison of the results obtained in these two scenarios allows us to draw some conclusions on the efficiency of organic farming in dry-farming conditions.
Speed of synchronization in complex networks of neural oscillators Analytic results based on Random Matrix Theory

description: We analyze the dynamics of networks of spiking neural oscillators. First, we present an exact linear stability theory of the synchronous state for networks of arbitrary connectivity. For general neuron rise functions, stability is determined by multiple operators, for which standard analysis is not suitable. We describe a general non-standard solution to the multi-operator problem. Subsequently, we derive a class of rise functions for which all stability operators become degenerate and standard eigenvalue analysis becomes a suitable tool. Interestingly, this class is found to consist of networks of leaky integrate and fire neurons. For random networks of inhibitory integrate-and-fire neurons, we then develop an analytical approach, based on the theory of random matrices, to precisely determine the eigenvalue distribution. This yields the asymptotic relaxation time for perturbations to the synchronous state which provides the characteristic time scale on which neurons can coordinate their activity in such networks. For networks with finite in-degree, i.e. finite number of presynaptic inputs per neuron, we find a speed limit to coordinating spiking activity: Even with arbitrarily strong interaction strengths neurons cannot synchronize faster than at a certain maximal speed determined by the typical in-degree.

Speeding up cloth simulation
Creators: name: Boxerman, Eddy
Publisher: name: University of British Columbia
Year: 2009

description: Simulating the motion of cloth is an important component in virtual character animation. Believable animations are now expected in feature films. Games and virtual reality are next, but the computational costs are still high. In this thesis we present a number of methods which reduce these costs, without losing accuracy or generality. To this end, we introduce a novel adaptive implicit-explicit time integration scheme, which takes advantage of simulation parameters — locally in both space and time — to improve the efficiency of the computation. Building upon this technique, we present a decomposition method which attempts to decouple the cloth mesh into multiple components that can be solved separately and in parallel. These techniques are introduced in the context of particle-system models, and include discussions on a variety of modelling and simulation issues. We also significantly improve the efficiency of the modified preconditioned conjugate gradient technique often used in cloth simulation for implicit integration schemes. We present improvements in the form of a preconditioner for the constrained problem and a better initial guess.
Farm Tourism and Spatial Competition

description: Changes in EU agricultural policies towards an increased focus on rural development issues raise questions regarding the economic impact of local and regional spatial competition. Farmers are typically price takers in the traditional markets for the major agricultural products. This is, however, not necessarily the case for “new enterprises” active in local and regional markets. This paper examines local/regional spatial competition for farm tourism. A spatial econometrics framework is applied to a hedonic pricing model. It is shown that spatial dependence affects the pricing of both Self-catering and Bed & Breakfast. However, the results indicate that local/regional competition may have a positive effect on the former but a negative effect on the latter. The findings illustrate the potential importance of local competition for rural developments studies.
“Intermittency: the differential of time and the integral of space. The intensive spatiality of the Monad, the Apokatastasis and the Messianic World in Benjamin's latest thinking”

description: The main topic of my paper concerns the theological-philosophical nexus between the intensive and qualitative spatiality of the Monad and the Origenian idea of Apokatastasis as a nexus that can clarify Benjamin's latest idea of the Messianic World. The first step will be, therefore, to explain (1) Benjamin's use of the Origenian notion of Apokatastasis in his Essay on Leskov and in the Passagenwerk. Secondly, I will discuss (2) how and to what extent such use is relevant for Benjamin's idea of Messianism. Thirdly, I will propose (3) the thesis that, for Benjamin, a messianic idea of time implies a monadological idea of space. In this regard, the relationship between continuity and discontinuity, which is crucial to understand the late Benjamin's idea of history, must be understood precisely as a dialectical relationship that involves not only time but also space. (4 ) The figure of intermittence – as we shall see – expresses in the most suitable way the intertwining of space and time as dialectically and messianicaly oriented. This sequence of logical steps and critical considerations will shed light on the true nature of Benjamin's idea of dialectics and on its relationship to the idea of the totality. The real term of confrontation of Benjamin's late philosophy (from the Passagenwerk to the Theses on the concept of history) does not concern, therefore, Heidegger, but Hegel. In the light of this confrontation, Heidegger's Being and Time is already in pieces. It is as it were – we can say – behind Benjamin's movement of thought.
