The Pondicherry interpretation of quantum mechanics: An overview
Creators: name: Mohrhoff, Ulrich
Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: An overview of the Pondicherry interpretation of quantum mechanics is presented. This interpretation proceeds from the recognition that the fundamental theoretical framework of physics is a probability algorithm, which serves to describe an objective fuzziness (the literal meaning of Heisenberg's term "Unschaerfe," usually mistranslated as "uncertainty") by assigning objective probabilities to the possible outcomes of unperformed measurements. Although it rejects attempts to construe quantum states as evolving ontological states, it arrives at an objective description of the quantum world that owes nothing to observers or the goings-on in physics laboratories. In fact, unless such attempts are rejected, quantum theory's true ontological implications cannot be seen. Among these are the radically relational nature of space, the numerical identity of the corresponding relata, the incomplete spatiotemporal differentiation of the physical world, and the consequent top-down structure of reality, which defies attempts to model it from the bottom up, whether on the basis of an intrinsically differentiated spacetime manifold or out of a multitude of individual building blocks.

description: Systems of exchange-coupled spins are commonly used to model ferromagnets. The quantum correlations in such magnets are studied using tools from quantum information theory. Isotropic ferromagnets are shown to possess a universal low-temperature density matrix which precludes entanglement between spins, and the mechanism of entanglement cancellation is investigated, revealing a core of states resistant to pairwise entanglement cancellation. Numerical studies of one-, two-, and three-dimensional lattices as well as irregular geometries showed no entanglement in ferromagnets at any temperature or magnetic field strength.

description: We present the result of a systematic search for the iron Kalpha fluorescent line at 6.4 keV among 1616 X-ray sources detected by ultra-deep Chandra observations of the Orion Nebula Cluster and the obscured Orion Molecular Cloud 1 population as part of the Chandra Orion Ultra-deep Project (COUP). Seven sources are identified to have an excess emission at 6.4 keV among 127 control sample sources with significant counts in the 6.0-9.0 keV band. These seven sources are young stellar objects (YSOs) characterized by intense flare-like flux variations, thermal spectra, and near-infrared (NIR) counterparts. The observed equivalent widths of the line cannot be attributed to the fluorescence by interstellar or circumstellar matter along the line of sight. The X-ray spectral fits and NIR colors of the 6.4 keV sources show that these sources have X-ray absorption of > 1x10^22 cm^(-2) and NIR excess emission, which is not expected when the fluorescence occurs at the stellar photosphere. We therefore conclude that the iron fluorescent line of YSOs arises from reflection off of circumstellar disks, which are irradiated by the hard X-ray continuum emission of magnetic reconnection flares.

description: Connections between protected areas, tourism and development of the countryside were studied in the examples of the Triglav National Park and the Kozjanski Park. 200 local inhabitants were interviewed in each area. According to the results, it can be concluded that the studied protected areas give an opportunity to develop rural tourism. It cannot be claimed that the development of tourism in protected areas is more successful than the development of tourism outside the protected areas. The interviewed inhabitants of the Triglav National Park most support the development of tourism in the area (86.5 %) out of all other industries, whereas this is not true for the interviewed inhabitants of the Kozjanski Park. The latter agree the area should be oriented in agriculture and the development of small business and craft. Nevertheless it is not insignificant that a high share of the interviewed inhabitants of the Kozjanski Park agrees on focusing this area on tourism development (74.5 %). Almost half of the interviewed inhabitants of the Triglav National Park (47 %) and only 15 % of the interviewed inhabitants of the Kozjanski Park agree that the opportunity of the protected area is a better possibility in tourism business. Thus we can conclude that the Triglav National Park offers more opportunities or additional possibilities for business in tourism than the Kozjanski Park. In the protected area, where tourism is more developed (the Triglav National Park), the interviewed inhabitants believe that the nature conservation strategies are less successful and perceive more negative burdens of tourism (traffic and crowds, higher prices). On the contrary, in the protected area, where tourism is less developed (the Kozjanski Park), the interviewed inhabitants observe that nature conservation strategies are more successful and they are less influenced by tourism.

description: This paper investigates the question of promotion of more efficient use of energy and for an increase in supply and use of energy from the renewable sources of energy in rural areas. The empirical research is based on the analysis of the survey evidence that is obtained by the written questionnaire. The 516 in-depth surveys were conducted among the scholars, students, and employees from social sciences, natural sciences, electrical energy supply, and energy management in the six different towns in Slovenia. The surveys data are analysed by using descriptive statistics, comparisons of average values, correlation, and multivariate factor analysis. The needs for more efficient energy use between different users and the significance of production of renewable sources of energy from different sources have been confirmed. This has implications for rationalization of energy supply, efficient energy use and use of the renewable sources of energy for more underlined environmental protection and the sustainable development.

description: Modern neural networks (NN) featuring a large number of layers (depth) and units per layer (width) have achieved a remarkable performance across many domains. While there exists a vast literature on the interplay between infinitely wide NNs and Gaussian processes, a little is known about analogous interplays with respect to infinitely deep NNs. NNs with independent and identically distributed (i.i.d.) initializations exhibit undesirable forward and backward propagation properties as the number of layers increases. To overcome these drawbacks, Peluchetti and Favaro (2020) considered fully-connected residual networks (ResNets) with network's parameters initialized by means of distributions that shrink as the number of layers increases, thus establishing an interplay between infinitely deep ResNets and solutions to stochastic differential equations, i.e. diffusion processes, and showing that infinitely deep ResNets does not suffer from undesirable forward-propagation properties. In this paper, we review the results of Peluchetti and Favaro (2020), extending them to convolutional ResNets, and we establish analogous backward-propagation results, which directly relate to the problem of training fully-connected deep ResNets. Then, we investigate the more general setting of doubly infinite NNs, where both network's width and network's depth grow unboundedly. We focus on doubly infinite fully-connected ResNets, for which we consider i.i.d. initializations. Under this setting, we show that the dynamics of quantities of interest converge, at initialization, to deterministic limits. This allow us to provide analytical expressions for inference, both in the case of weakly trained and fully trained ResNets. Our results highlight a limited expressive power of doubly infinite ResNets when the unscaled network's parameters are i.i.d. and the residual blocks are shallow.

description: Employing a real time effective action formalism we analyze electron transport and current fluctuations in comparatively short coherent conductors in the presence of electron-electron interactions. We demonstrate that, while Coulomb interaction tends to suppress electron transport, it may {\it strongly enhance} shot noise in scatterers with highly transparent conducting channels. This effect of excess noise is governed by the Coulomb gap observed in the current-voltage characteristics of such scatterers. We also analyze the frequency dispersion of higher current cumulants and emphasize a direct relation between electron-electron interaction effects and current fluctuations in disordered mesoscopic conductors.

description: Feedback from radio jets associated with Active Galactic Nuclei (AGN) plays a profound role in the evolution of galaxies. Kinetic power of these radio jets appears to show temporal variation, but the mechanism(s) responsible for this process are not yet clear. Recently, the LOw Frequency ARray (LOFAR) has uncovered large populations of active, remnant and restarted radio jet populations. By focusing on LOFAR data in the Lockman Hole, in this work we use the Radio AGN in Semi-Analytic Environments (RAiSE) dynamical model to present the first self-consistent modelling analysis of active, remnant and restarted radio source populations. Consistent with other recent work, our models predict that remnant radio lobes fade quickly. Any high (>10 percent) observed fraction of remnant and restarted sources therefore requires a dominant population of short-lived jets. We speculate that this could plausibly be provided by feedback-regulated accretion.

description: The main objective of the present paper is to reveal the most important reasons for admitting and supporting a local factor, such as a Union of Agricultural Cooperatives, by the rural residents of a typical Greek region. Moreover, the investigation of the possible dependence relationships among the socioeconomic variables of a market research, which refers to the willingness to purchase dairy products from the Cooperative (the dependent variable) and the independent variables, constitute the intention of the paper. From a methodological point of view, the study extends the employment of categorical multivariate methodologies into rural development issues. Interesting results are revealed from the segmentation of rural populations regarding the drivers of project adoption. In particular, the majority of the potential adopters of the local project face the same, more or less, challenges in supporting local cooperative projects and therefore in supporting their incomes. The survey results indicate the success of the investment project of the Union and the confidence of the local community in a local cooperative organization in supporting the development of the region.

description: The paper provides analysis of dairy farms in the Baltic States, their development since accessing EU. During this period the specialisation level has increased but the total number of farms has fast reduced. The total economic indicators increased until 2007, but they still significantly lag behind Western Europe. Big investment has been made, but in the result, the cost level has not reduced but even increased, which has several reasons. Thus many farms were not ready to survive the economic downturn. The results of the research allow concluding that when planning future support for dairy industry the main attention should be paid to introducing cost competitive technologies, supporting cooperation in the purchase and use of fixed assets; it is necessary to educate farmers in efficient business management, as well as to facilitate integration of milk producing and processing enterprises.
Distinción y periferia en el discurso de la prensa ilustrada : Plus ultra (1916-1930)
Creators: name: Carbonetti, Maria
Publisher: name: University of British Columbia
Year: 2009

description: The following investigation examines the discourse of the press in Plus Ultra, a magazine for the Argentinean aristocratic elite, published in Buenos Aires between 1916 and 1930. Plus Ultra emerges during a unique historical period, when nationalism confronts the alternative ideologies of socialism and anarchism. The magazine welcomes and publishes its last issue in 1930 shortly after the first coup d'état led by General Uriburu took place. This thesis undertakes the study of the complete edition of the magazine from the point of view of the practices of distinction, by which cultural, symbolic, and material consumption establish a dialogue with the modern nature of the magazine as a means of mass communication. The relationship between distinction and modernity reveals the tensions within the elite's needs to consolidate its social and political power and the impetus of progress endorsed by the same social group. In doing so, Plus Ultra exposes the diminishing power of the oligarchy through an agenda based on self-referentiality and allegory between family genealogy and national history. The magazine blends the contents of high culture with the social manners of the oligarchy. From a Cultural Studies perspective, which includes concepts and notions developed by Raymond Williams and Pierre Bourdieu, as well as contributions from Fredric Jameson, Walter Benjamin and Benedict Anderson, Plus Ultra reveals to be a unique publication among the numerous newspapers and magazines of the time. Its corpus includes chronicles, literary texts, images and graphic design. Moreover, Plus Ultra exposes the main theoretical and methodological problems that the miscellaneous press poses. To date, in Latin America an in-depth study of this type of cultural artifact, has not been carried out.

description: In recent years, convolutional neural network has gained popularity in many engineering applications especially for computer vision. In order to achieve better performance, often more complex structures and advanced operations are incorporated into the neural networks, which results very long inference time. For time-critical tasks such as autonomous driving and virtual reality, real-time processing is fundamental. In order to reach real-time process speed, a light-weight, high-throughput CNN architecture namely RoadNet-RT is proposed for road segmentation in this paper. It achieves 90.33% MaxF score on test set of KITTI road segmentation task and 8 ms per frame when running on GTX 1080 GPU. Comparing to the state-of-the-art network, RoadNet-RT speeds up the inference time by a factor of 20 at the cost of only 6.2% accuracy loss. For hardware design optimization, several techniques such as depthwise separable convolution and non-uniformed kernel size convolution are customized designed to further reduce the processing time. The proposed CNN architecture has been successfully implemented on an FPGA ZCU102 MPSoC platform that achieves the computation capability of 83.05 GOPS. The system throughput reaches 327.9 frames per second with image size 1216x176.

description: The dynamics of a ring of vortices in two-dimensional Bose-Einstein condensates (with and without an additional vortex at the center) is studied for (1) a uniform condensate in a rigid cylinder and (2) a nonuniform trapped condensate in the Thomas-Fermi limit. The sequence of ground states (within these single-ring configurations) is determined as a function of the external rotation frequency by comparing the free energy of the various states. For each ground state, the Tkachenko-like excitations and the associated dynamical stability are analyzed.

description: The geometric distribution of high-energy hadrons >100 GeV in shower cores measured with the KASCADE calorimeter is analyzed. The data are checked for sensitivity to hadronic interaction features and indications of new physics as discussed in the literature. The angular correlation of the most energetic hadrons and in particular the fraction of events with hadrons being aligned are quantified by means of the commonly used parameter lambda_4. The analysis shows that the observed lambda_4 distribution is compatible with that predicted by simulations and is not linked to an angular correlation from hadronic jet production at high energy. Another parameter, d_4^max, describing distances between hadrons measured in the detector, is found to be sensitive both to the transverse momenta in secondary hadron production and the primary particle type. Transverse momenta in high-energy hadron interactions differing by a factor two or more from what is assumed in the standard simulations are disfavoured by the measured d_4^max distribution.

description: Robotics have recently contributed to cosmological spectroscopy to automatically obtain the map of the observable universe using robotic fiber positioners. For this purpose, an assignment algorithm is required to assign each robotic fiber positioner to a target associated with a particular observation. The assignment process directly impacts on the coordination of robotic fiber positioners to reach their assigned targets. In this paper, we establish an optimal target assignment scheme which simultaneously provides the fastest coordination accompanied with the minimum of colliding scenarios between robotic fiber positioners. In particular, we propose a cost function by whose minimization both of the cited requirements are taken into account in the course of a target assignment process. The applied simulations manifest the improvement of convergence rates using our optimal approach. We show that our algorithm scales the solution in quadratic time in the case of full observations. Additionally, the convergence time and the percentage of the colliding scenarios are also decreased in both supervisory and hybrid coordination strategies.

description: SN2002kg is a type IIn supernova, detected in October 2002 in the nearby spiral galaxy NGC 2403. We show that the position of SN2002kg agrees within the errors with the position of the LBV V37. Ground based and HST ACS images however show that V37 is still present after the SN2002kg event. We compiled a lightcurve of V37 which underlines the variablity of the object, and shows that SN2002kg was the brightening of V37 and not a supernova. The recent brightening is not a giant eruption, but more likely part of an S Dor phase. V37 shows strong Halpha +[NII] emission in recent images and in the SN2002kg spectrum, which we interprete as the signature of the presence of an LBV nebula. A historic spectrum lacks emission, which may hint that we are witnessing the formation of an LBV nebula.

Thanks to Gaia-DR2$^3$ and spectroscopic surveys$^4$, the stellar remnants of such mergers have been identified$^{5-7}$. The chronological dating of such events is crucial to uncover the formation and evolution of the Galaxy at high redshift, but it has so far been challenging owing to difficulties in obtaining precise ages for these oldest stars. Here we combine asteroseismology -- the study of stellar oscillations -- with kinematics and chemical abundances, to estimate precise stellar ages ($\sim$ 11%) for a sample of stars observed by the $\mathit{Kepler}$ space mission$^8$. Crucially, this sample includes not only some of the oldest stars that were formed inside the Galaxy, but also stars formed externally and subsequently accreted onto the Milky Way. Leveraging this resolution in age, we provide compelling evidence in favour of models in which the Galaxy had already formed a substantial population of its stars (which now reside mainly in its thick disc) before the in-fall of the satellite galaxy Gaia-Enceladus/Sausage$^{5,6}$ around 10 billions years ago

description: Empirical evidence and microeconomic theory suggest that, in many settings, farm household production and consumption decisions are "non-separable." Non-separability may have important policy implications, including lack of response or threshold effects when incentives change. This paper extends the literature in two ways. First, we develop a non-separable farm household model with transaction costs and endogenous choice of market "regime" (surplus, self-sufficiency, or deficit) for production-consumption items (commodities and factors that are both demanded and supplied by the household). Second, we embed this household model in an economy-wide computable general equilibrium model which is formulated as a mixed-complementarity problem. Simulations with a model based on data for a stylized, low-income, Sub-Saharan African country show that the proposed formulation enhances our ability to analyze the impact of exogenous changes on African farmers.

description: The idea of quantum state storage is generalized to describe the coherent transfer of quantum information through a coherent data bus. In this universal framework, we comprehensively review our recent systematical investigations to explore the possibility of implementing the physical processes of quantum information storage and state transfer by using quantum spin systems, which may be an isotropic antiferromagnetic spin ladder system or a ferromagnetic Heisenberg spin chain. Our studies emphasize the physical mechanisms and the fundamental problems behind the various protocols for the storage and transfer of quantum information in solid state systems.

description: This paper presents an overview of macroeconomic and agricultural trends in Latin America and the Caribbean. It argues that world-level macroeconomic and agricultural cycles, of expansion during the 1960s and 1970s, and stagnation and retrenchment during the 1980's, had an important impact on the economies of the LAC countries and on the performance of the agricultural sector in the region. They played over, and interacted with, a sustained trend of technological change in agriculture, that had begun in the developed countries before, and that in the last quarter of a century spread to developing countries.

Conformal Geometry and Invariants of 3-strand Brownian Braids

description: We propose a simple geometrical construction of topological invariants of 3-strand Brownian braids viewed as world lines of 3 particles performing independent Brownian motions in the complex plane z. Our construction is based on the properties of conformal maps of doubly-punctured plane z to the universal covering surface. The special attention is paid to the case of indistinguishable particles. Our method of conformal maps allows us to investigate the statistical properties of the topological complexity of a bunch of 3-strand Brownian braids and to compute the expectation value of the irreducible braid length in the non-Abelian case.

description: A long-term goal of reinforcement learning agents is to be able to perform tasks in complex real-world scenarios. The use of external information is one way of scaling agents to more complex problems. However, there is a general lack of collaboration or interoperability between different approaches using external information. In this work, while reviewing externally-influenced methods, we propose a conceptual framework and taxonomy for assisted reinforcement learning, aimed at fostering collaboration by classifying and comparing various methods that use external information in the learning process. The proposed taxonomy details the relationship between the external information source and the learner agent, highlighting the process of information decomposition, structure, retention, and how it can be used to influence agent learning. As well as reviewing state-of-the-art methods, we identify current streams of reinforcement learning that use external information in order to improve the agent's performance and its decision-making process. These include heuristic reinforcement learning, interactive reinforcement learning, learning from demonstration, transfer learning, and learning from multiple sources, among others. These streams of reinforcement learning operate with the shared objective of scaffolding the learner agent. Lastly, we discuss further possibilities for future work in the field of assisted reinforcement learning systems.

description: There is a continuing need to use recent and consistent multisectoral economic data to support policy analysis and the development of economywide models. Updating and estimating input-output tables and Social Accounting Matrices (SAMs) for a recent year is a difficult and a challenging problem. Typically, input-output data are collected at long intervals (usually five years or more), while national income and product data are available annually, but with a lag. Supporting data also come from a variety of sources; e.g., censuses of manufacturing, labor surveys, agricultural data, government accounts, international trade accounts, and household surveys. The traditional RAS approach requires that we start with a consistent SAM for a particular period and “update” it for a later period given new information on row and column sums. This paper extends the RAS method by proposing a flexible entropy difference approach to estimating a consistent SAM starting from inconsistent data estimated with error, a common experience in many countries. The method is flexible and powerful when dealing with scattered and inconsistent data. It allows incorporating errors in variables, inequality constraints, and prior knowledge about any part of the SAM (not just row and column sums). Since the input-output accounts are contained within the SAM framework, updating an input-output table can be viewed as a special case of the general SAM estimation problem. The paper presents the structure of a SAM and a mathematical description of the estimation problem. It then describes the classical RAS procedure and the entropy difference approach. An example of the entropy difference approach applied to the case of Mozambique is presented. In addition, an appendix includes a listing of the computer code in the GAMS language used in the procedure.

Income effects of alternative trade policy adjustments on Philippine rural households: a general equilibrium analysis

description: Three types of trade policy adjustments to deal with an unsustainable current account deficit are examined in this paper for their economywide income and equity effects, based on the results of simulation experiments using a CGE model of the Philippine economy. Gross domestic product (GDP) expectably decreases with import rationing and less markedly, with the imposition of a general import surtax; by contrast, adjustment through the reduction of tariffs leads to a larger GDP. The latter result, however, is counterbalanced by a substantial loss in government income. With respect to the distribution of income gains (and losses), the additional market distortions and rent-seeking that accompany the implementation of import rationing heavily discriminate in favor of Metro Manila households, whose average income is the highest among the five household groups distinguished in the model. Moving to a general import surtax represents an improvement in that non-Metro Manila households are penalized less. However, these first two policy options are deemed inferior to tariff liberalization--which yields larger income benefits to small-farm and "other rural" households relative to the more affluent Metro Manila, other urban, and large-farm households.

Chiral asymmetry in the weak interaction via Clifford Algebras

description: Despite its tremendous success, the Standard Model of particle physics does not explain why the weak interaction breaks chiral symmetry. Various unified theories got us closer to an answer, but too often the explanation consists of labeling the $\operatorname{SU}(2)_w$ singlet representations as right-handed, and the doublet ones as left handed. This by itself does not ensure a chiral preference, because chirality itself, arising in the Dirac spinors, is not a property of the internal gauge group representations. Something deeper than mere labeling is required. In this paper, some of the progress using exterior and Clifford algebras is reviewed, and a possible explanation for chiral asymmetry is presented. It is shown how such a solution is present, rather implicitly, in a model proposed in a previous article.
