    2000-01-01

    根据《棋经十三篇》这一部棋书,通过分析,看到了《棋经》与《孙子》的关系甚为密切,它不仅从篇章款式上摹拟《孙子十三篇》,而更是从有关棋的战略战术等内容问题上与《孙子十三篇》相吻合。因此,棋道如兵法,棋理合乎一般事物之辩证法则。%After analysing thirteen chapters of the Weiqi classic,we learned that this classic has much to do with the book master sun's art of war,both of them are identical not only in their writing structures but also in their contents such as strategies and tactics.Therefore,the ways of Weiqi is the same as the art of war with its principles in comformity with the dialectical law of the development of things.So the ways of Weiqi is the ways of the world.On character (one of thirteen charpters of the Weiqi classic)expounds nine kinds of moral quality in the players' skills in Weiqi.Considering the relationship of the methods of playing Weiqi to the players' characters,we can conclude that the heart of Weiqi is the heart of human.

    This chapter outlines the epidemiology of brucellosis in the Russian Federation and in five countries bordering Russia. Since the Soviet Union's dissolution, Russia and the newly formed independent republics have failed to maintain policies to control brucellosis and other zoonotic diseases. Many of these republics, due to weak animal control and prevention systems and dangerous food preparation practices, are still burdened with the human cost of brucellosis. The final summary of this section provides an example of the successful transboundary cooperative efforts between Arizona and Mexico, which could be applied to the situation between Russia and the bordering independent republics.

    The author had initiated a revision and translation of "Classical Diophantine Equations" prior to his death. Given the rapid advances in transcendence theory and diophantine approximation over recent years, one might fear that the present work, originally published in Russian in 1982, is mostly superseded. That is not so. A certain amount of updating had been prepared by the author himself before his untimely death. Some further revision was prepared by close colleagues. The first seven chapters provide a detailed, virtually exhaustive, discussion of the theory of lower bounds for linear forms in the logarithms of algebraic numbers and its applications to obtaining upper bounds for solutions to the eponymous classical diophantine equations.

    Disease control in domestic fleet in XVIII century was a part of government measures concerning protection of the territory of the Russian Empire from the penetration of dangerous infectious diseases. Understanding the role fleet could play in the spread of infection, the government sought to prevent its entry from the sea. Following this task, in the early 20-s of XVIII century on islands of the Gulf Seskar and Wolf organized sanitary quarantine stations where ships from unfavorable in relation to the epidemic areas stayed before they pester the Russian shore. Eventually when the Black Sea Fleet was created, similar items appeared in Ochakov, Sevastopol, Feodosia, Yalta and Kerch. In XVIII century health legislation was supplemented by a number of regulations relating to the activities of the fleet. In particular, during the reign of Peter I epidemic rules were composed, which, as it became known, lasted for about sixty years. In 1786, the band released a set of quarantine rules designed to streamline the work of sanitary and quarantine stations. Important for protection against the penetration of Russian borders infectious diseases had timely warning of epidemics broke out abroad. Cooperating with European countries in the prevention and control of communicable diseases, Russia has successfully developed methods antiepidemic protection.

    Stream temperature has direct and indirect effects on stream ecology and is critical in determining both abiotic and biotic system responses across a hierarchy of spatial and temporal scales. Temperature variation is primarily driven by solar radiation, while landscape topography, geology, and stream reach scale ecosystem processes contribute to local variability. Spatiotemporal heterogeneity in freshwater ecosystems influences habitat distributions, physiological functions, and phenology of all aquatic organisms. In this chapter we provide an overview of methods for monitoring stream temperature, characterization of thermal profiles, and modeling approaches to stream temperature prediction. Recent advances in temperature monitoring allow for more comprehensive studies of the underlying processes influencing annual variation of temperatures and how thermal variability may impact aquatic organisms at individual, population, and community based scales. Likewise, the development of spatially explicit predictive models provide a framework for simulating natural and anthropogenic effects on thermal regimes which is integral for sustainable management of freshwater systems.

    With the development of modern industry and modern economies, environmental problems, especially water pollution and water scarcity, have become the most serious global challenges. In dealing with these challenges, various kinds of functionalized materials and devices are purposefully developed, fabricated, and utilized. It is clear that smart materials have not only provided effective strategies for solving environmental problems, but have also exhibited unprecedented advantages over traditional materials by integrating multifunctions and/or processes into one advanced device/material. In this book, we will present a broad collection of bioinspired smart materials and systems that are used in environmental problem solving. The topics of these chapters span from bioinspired fog collection, self-healing materials, responsive particle-stabilized emulsions, smart draw solutions in forward osmosis, slippery coating, insightful analysis of problems and opportunities for hydrophobic surfaces applied in real conditions, to superwetting materials for oil-water separation.

    2016-07-01

    This chapter of the 2016 Billion-Ton Report provides an estimate of biomass potential at given minimum selling prices. This is not a projection of actual measured biomass or a simulation of commercial projects. Biomass potential is estimated based on 30 years of hourly local climate and strain-specific biophysical characteristics using the Biomass Assessment Tool (BAT), assuming sufficient available nutrients (including CO2). As is the case for terrestrial feedstocks, important resource analysis questions for algae include not only how much of the crop may be available but also what price might be needed to procure that supply. Identifying resource co-location opportunities for algal biofuel facilities has the potential to reduce costs, utilize waste resources, and focus attention on appropriate technologies and locations for commercialization.

    Human activity in the last century has led to a substantial increase in nitrogen (N) emissions and deposition (Galloway et al. 2003). Because of past, and, in some regions, continuing increases in emissions (Lehmann et al. 2005, Nilles and Conley 2001), this N deposition has reached a level that has caused or is likely to cause alterations and damage in many ecosystems across the United States. In some ecoregions, the impact of N deposition has been severe and has changed the biotic community structure and composition of ecosystems. In the Mediterranean California ecoregion, for example (see Chapter 13), replacement of native by exotic invasive vegetation is accelerated because exotic species are often more productive under elevated N deposition than native species in some California grasslands, coastal sage scrub, and desert scrub (Fenn et al. 2010, Rao and Allen 2010, Rao et al. 2010, Weiss 1999, Yoshida and Allen 2004). Such shifts in plant community composition and species richness can have consequences beyond changes in ecosystem structure: shifts may lead to overall losses in biodiversity and further impair particular threatened or endangered species (Stevens et al. 2004). Th e extirpation of the endangered checkerspot butterfl y (Euphydryas editha bayensis), because the host plant for the larval stage disappears in N-enriched ecosystems (Fenn et al. 2010, Weiss 1999), is just one example of the detrimental impacts of elevated N deposition.

    2013-01-01

    In the late 1970s, while the CERN community was busy preparing the SPS to operate as a collider and planning for LEP, people also had their eyes on the next chapter in the unfolding story of CERN.   That the LEP tunnel should be built with a future hadron collider in mind was a given by the end of the decade. But there had also been proposals to build large proton storage rings, or re-equip the ISR with superconducting magnets. Some people had suggested building an electron-proton collider at CERN, and there were ambitious plans looking far into the future at a possible Very Big Accelerator to be built somewhere in the world, which went by its acronym VBA. For the field of particle physics, with its very long lead times, this is part of the normal cycle, and while most of those options never came to fruition, this process did pave the way for the LHC. Today, with the LHC programme underway, the time has come for CERN to start seriously considering the options for its post-LHC future. Perhaps ...

  17. Collective Intelligence. Chapter 17

    Wolpert, David H.

    2003-01-01

    Many systems of self-interested agents have an associated performance criterion that rates the dynamic behavior of the overall system. This chapter presents an introduction to the science of such systems. Formally, collectives are defined as any system having the following two characteristics: First, the system must contain one or more agents each of which we view as trying to maximize an associated private utility; second, the system must have an associated world utility function that rates the possible behaviors of that overall system. In practice, collectives are often very large, distributed, and support little, if any, centralized communication and control, although those characteristics are not part of their formal definition. A naturally occurring example of a collective is a human economy. One can identify the agents and their private utilities as the human individuals in the economy and the associated personal rewards they are each trying to maximize. One could then identify the world utility as the time average of the gross domestic product. ("World utility" per se is not a construction internal to a human economy, but rather something defined from the outside.) To achieve high world utility it is necessary to avoid having the agents work at cross-purposes lest phenomena like liquidity traps or the Tragedy of the Commons (TOC) occur, in which agents' individually pursuing their private utilities lowers world utility. The obvious way to avoid such phenomena is by modifying the agents utility functions to be "aligned" with the world utility. This can be done via punitive legislation. A real-world example of an attempt to do this was the creation of antitrust regulations designed to prevent monopolistic practices.

  20. Chapter 59: Web Services

    Science.gov (United States)

    Graham, M. J.

    Web services are a cornerstone of the distributed computing infrastructure that the VO is built upon yet to the newcomer, they can appear to be a black art. This perception is not helped by the miasma of technobabble that pervades the subject and the seemingly impenetrable high priesthood of actual users. In truth, however, there is nothing conceptually difficult about web services (unsurprisingly any complexities will lie in the implementation details) nor indeed anything particularly new. A web service is a piece of software available over a network with a formal description of how it is called and what it returns that a computer can understand. Note that entities such as web servers, ftp servers and database servers do not generally qualify as they lack the standardized description of their inputs and outputs. There are prior technologies, such as RMI, CORBA, and DCOM, that have employed a similar approach but the success of web services lies predominantly in its use of standardized XML to provide a language-neutral way for representing data. In fact, the standardization goes further as web services are traditionally (or as traditionally as five years will allow) tied to a specific set of technologies (WSDL and SOAP conveyed using HTTP with an XML serialization). Alternative implementations are becoming increasingly common and we will cover some of these here. One important thing to remember in all of this, though, is that web services are meant for use by computers and not humans (unlike web pages) and this is why so much of it seems incomprehensible gobbledegook. In this chapter, we will start with an overview of the web services current in the VO and present a short guide on how to use and deploy a web service. We will then review the different approaches to web services, particularly REST and SOAP, and alternatives to XML as a data format. We will consider how web services can be formally described and discuss how advanced features such as security, state

  1. Primitive Ontology and the Classical World

    Science.gov (United States)

    Allori, Valia

    In this chapter, I present the common structure of quantum theories with a primitive ontology (PO), and discuss in what sense the classical world emerges from quantum theories as understood in this framework. In addition, I argue that the PO approach is better at analyzing the classical limit than the rival wave function ontology approach or any other approach in which the classical world is non-reductively "emergent:" even if the classical limit within this framework needs to be fully developed, the difficulties are technical rather than conceptual, while this is not true for the alternatives.

    The sequence of classic paradigms in taxonomy that partly replaced each other and partly co-exist is given as follows: the theory of "organ and organism similarity", the naturalistic theory, the descriptive theory, and the phylogenetic theory. The naturalistic classics accepted the notion of "the plan of creation". The rejection of appealing to this plan brought forth certain problems in the formulation of the purpose of taxonomy; these problems were differently solved by the descriptive and the phylogenetic classic traditions. The difficulties of the current paradigms arising from the loss of a "strong purpose", a problem to be solved by taxonomists that is to be clear and interesting to a wide range of non-professionals. The paradox of formalization led to the losing of content of the methods due to their formalization. To attract attention to taxonomy, a new "image of the results" of its work that would be interesting to the non-professionals is necessary. The co-existence of different methods of reseach applied to different groups of facts leads to the loss of integrity of the research. It is not only that the taxon becomes a hypothesis and such hypotheses multiply. The comparison of these hypotheses is problematic, because each of them is supported by its own independent scope of facts. Because of the existence of a fundamental meronotaxonomic discrepancy, taxonomic systems based on different groups of characters appear to be incomparable, being rather systems of characters than systems of taxa. Systems of characters are not directly comparable with each other; they can be compared only through appealing to taxa, but taxa themselves exist only in the form of a number of hypotheses. Consequently, each separate taxonomic approach creates its own nature, its own subject of research. Therefore, it is necessary to describe the subject of research correctly (and indicate the purpose of research), as well as to distinguish clearly between results achieved through

  6. The classical theory of fields electromagnetism

    CERN Document Server

    Helrich, Carl S

    2012-01-01

    The study of classical electromagnetic fields is an adventure. The theory is complete mathematically and we are able to present it as an example of classical Newtonian experimental and mathematical philosophy. There is a set of foundational experiments, on which most of the theory is constructed. And then there is the bold theoretical proposal of a field-field interaction from James Clerk Maxwell. This textbook presents the theory of classical fields as a mathematical structure based solidly on laboratory experiments. Here the student is introduced to the beauty of classical field theory as a gem of theoretical physics. To keep the discussion fluid, the history is placed in a beginning chapter and some of the mathematical proofs in the appendices. Chapters on Green’s Functions and Laplace’s Equation and a discussion of Faraday’s Experiment further deepen the understanding. The chapter on Einstein’s relativity is an integral necessity to the text. Finally, chapters on particle motion and waves in a dis...

  7. Chapter 1: Direct Normal Radiation

    Energy Technology Data Exchange (ETDEWEB)

    Myer, Daryl R.

    2016-04-15

    This chapter addresses the quantitative and qualitative aspects of the solar resource, the direct solar radiation. It discusses the total or integrated broadband direct beam extraterrestrial radiation (ETR). This total integrated irradiance is comprised of photons of electromagnetic radiation. The chapter also discusses the impact of the atmosphere and its effect upon the direct normal irradiance (DNI) beam radiation. The gases and particulates present in the atmosphere traversed by the direct beam reflect, absorb, and scatter differing spectral regions and proportions of the direct beam, and act as a variable filter. Knowledge of the available broadband DNI beam radiation resource data is essential in designing a concentrating photovoltaic (CPV) system. Spectral variations in the DNI beam radiation affect the performance of a CPV system depending on the solar cell technology used. The chapter describes propagation and scattering processes of circumsolar radiation (CSR), which includes the Mie scattering from large particles.

    Full Text Available This recent addition to the excellent Blackwell Companions series looks at the various forms of classical reception currently being researched as well as those deemed to have future importance. The diversity and volume of the themes and approaches contained in this book are truly impressive. As Hardwick and Stray state in their introduction, this collection “has been constructed on the basis that the activators of reception are many and varied and that we all gain from encountering examples from outside our own immediate areas of knowledge” (p. 4. Throughout the book they stay true to this motto and traditional approaches to classical reception are not given prominence over more recent (sometimes contentious approaches such as film studies, cultural politics and photography. The same goes for the various cultures involved and there is even a chapter on Greek drama in South Africa.

    This chapter describes the use of Fourier transform spectrometers (FTS) for accurate spectrophotometry over a wide spectral range. After a brief exposition of the basic concepts of FTS operation, we discuss instrument designs and their advantages and disadvantages relative to dispersive spectrometers. We then examine how common sources of error in spectrophotometry manifest themselves when using an FTS and ways to reduce the magnitude of these errors. Examples are given of applications to both basic and derived spectrophotometric quantities. Finally, we give recommendations for choosing the right instrument for a specific application, and how to ensure the accuracy of the measurement results..

    CERN Document Server

    Scheck, Florian

    2012-01-01

    The book describes Maxwell's equations first in their integral, directly testable form, then moves on to their local formulation. The first two chapters cover all essential properties of Maxwell's equations, including their symmetries and their covariance in a modern notation. Chapter 3 is devoted to Maxwell theory as a classical field theory and to solutions of the wave equation. Chapter 4 deals with important applications of Maxwell theory. It includes topical subjects such as metamaterials with negative refraction index and solutions of Helmholtz' equation in paraxial approximation relevant for the description of laser beams. Chapter 5 describes non-Abelian gauge theories from a classical, geometric point of view, in analogy to Maxwell theory as a prototype, and culminates in an application to the U(2) theory relevant for electroweak interactions. The last chapter 6 gives a concise summary of semi-Riemannian geometry as the framework for the classical field theory of gravitation. The chapter concludes wit...

    Bandler, Lilon Gretl

    2015-12-01

    Chapter 4.7 of the National Statement on Ethical Conduct in Human Research refers specifically to Aboriginal and Torres Strait Islander Peoples. It lays out the points at which researchers working with Aboriginal and Torres Strait Islanders must consider their approach, and the engagement with individuals, communities or groups who are involved in or affected by their research. History, of Australia and of research involving Aboriginal and Torres Strait Islander Australians, has informed this approach. The response to that history has been a rational, institutionalised, systematic demand for a different perception of what should direct research and research processes to ensure engagement with and service to the community with whom the researchers wish to do the work. This paper considers whether these principles could inform the approach to other research work.

    2004-06-01

    Full Text Available The 18th century defense of tolerance rests upon two lines of argument; lines that we can observe in thinkers such as Montesquieu and Rousseau, Diderot, Romilly and Voltaire. The first deconstructs the concept of absolute truth as it applies not only to the (orthodox doctrine itself, as revealed by God, but also to the Catholic Church insofar as it is taken to be the only institution where truth resides uniquely. The second line of argument would run as follows: Once we acknowledge the rights of consciousness to every single religion, how can we possibly avoid a circular justification of intolerance? Romilly and Voltaire defend, without renouncing to the rights of consciousness (which are the base of individual liberties, the Lockean thesis of the separation Church-State. However, they assign to the State the ius circa sacra. It is only upon this foundation that the idea and the practice of tolerance, both religiously as well as universally and multiculturally speaking, can be constructed.

    La defensa de la tolerancia, en el siglo XVIII, se apoya en dos líneas de argumentación, que observamos en pensadores como Montesquieu y Rousseau, Diderot, Romilly y Voltaire. Una es la que deconstruye el concepto de verdad absoluta aplicado tanto a la doctrina (ortodoxa, por ello revelada por Dios como a la institución considerada única depositaria de tal verdad, la Iglesia católica, única «verdadera». Otra sigue este argumento: si se reconocen los derechos de la conciencia a toda confesión religiosa, ¿acaso podría evitarse una justificación circular de la intolerancia? Sin renunciar a los derechos de la conciencia, base de las libertades individuales, Romilly y Voltaire sostienen la separación Iglesia-Estado, como lo hiciera Locke, asignando a éste el ius circa sacra. Sólo sobre esta base se logra fundamentar la idea y la práctica de la tolerancia no sólo religiosa, sino también universal o multicultural.

  4. What classicality? Decoherence and Bohr's classical concepts

    CERN Document Server

    Schlosshauer, Maximilian

    2010-01-01

    Niels Bohr famously insisted on the indispensability of what he termed "classical concepts." In the context of the decoherence program, on the other hand, it has become fashionable to talk about the "dynamical emergence of classicality" from the quantum formalism alone. Does this mean that decoherence challenges Bohr's dictum and signifies a break with the Copenhagen interpretation-for example, that classical concepts do not need to be assumed but can be derived? In this paper we'll try to shine some light down the murky waters where formalism and philosophy cohabitate. To begin, we'll clarify the notion of classicality in the decoherence description. We'll then discuss Bohr's and Heisenberg's take on the quantum-classical problem and reflect on different meanings of the terms "classicality" and "classical concepts" in the writings of Bohr and his followers. This analysis will allow us to put forward some tentative suggestions for how we may better understand the relation between decoherence-induced classical...

    Baulieu, Laurent; Sénéor, Roland

    2017-01-01

    Quantum Field Theory has become the universal language of most modern theoretical physics. This introductory textbook shows how this beautiful theory offers the correct mathematical framework to describe and understand the fundamental interactions of elementary particles. The book begins with a brief reminder of basic classical field theories, electrodynamics and general relativity, as well as their symmetry properties, and proceeds with the principles of quantisation following Feynman's path integral approach. Special care is used at every step to illustrate the correct mathematical formulation of the underlying assumptions. Gauge theories and the problems encountered in their quantisation are discussed in detail. The last chapters contain a full description of the Standard Model of particle physics and the attempts to go beyond it, such as grand unified theories and supersymmetry. Written for advanced undergraduate and beginning graduate students in physics and mathematics, the book could also serve as a re...

  8. Chapter 4: Geological Carbon Sequestration

    Energy Technology Data Exchange (ETDEWEB)

    Friedmann, J; Herzog, H

    2006-06-14

    Carbon sequestration is the long term isolation of carbon dioxide from the atmosphere through physical, chemical, biological, or engineered processes. The largest potential reservoirs for storing carbon are the deep oceans and geological reservoirs in the earth's upper crust. This chapter focuses on geological sequestration because it appears to be the most promising large-scale approach for the 2050 timeframe. It does not discuss ocean or terrestrial sequestration. In order to achieve substantial GHG reductions, geological storage needs to be deployed at a large scale. For example, 1 Gt C/yr (3.6 Gt CO{sub 2}/yr) abatement, requires carbon capture and storage (CCS) from 600 large pulverized coal plants ({approx}1000 MW each) or 3600 injection projects at the scale of Statoil's Sleipner project. At present, global carbon emissions from coal approximate 2.5 Gt C. However, given reasonable economic and demand growth projections in a business-as-usual context, global coal emissions could account for 9 Gt C. These volumes highlight the need to develop rapidly an understanding of typical crustal response to such large projects, and the magnitude of the effort prompts certain concerns regarding implementation, efficiency, and risk of the enterprise. The key questions of subsurface engineering and surface safety associated with carbon sequestration are: (1) Subsurface issues: (a) Is there enough capacity to store CO{sub 2} where needed? (b) Do we understand storage mechanisms well enough? (c) Could we establish a process to certify injection sites with our current level of understanding? (d) Once injected, can we monitor and verify the movement of subsurface CO{sub 2}? (2) Near surface issues: (a) How might the siting of new coal plants be influenced by the distribution of storage sites? (b) What is the probability of CO{sub 2} escaping from injection sites? What are the attendant risks? Can we detect leakage if it occurs? (3) Will surface leakage negate or

    Xochitl C Morgan

    Full Text Available Humans are essentially sterile during gestation, but during and after birth, every body surface, including the skin, mouth, and gut, becomes host to an enormous variety of microbes, bacterial, archaeal, fungal, and viral. Under normal circumstances, these microbes help us to digest our food and to maintain our immune systems, but dysfunction of the human microbiota has been linked to conditions ranging from inflammatory bowel disease to antibiotic-resistant infections. Modern high-throughput sequencing and bioinformatic tools provide a powerful means of understanding the contribution of the human microbiome to health and its potential as a target for therapeutic interventions. This chapter will first discuss the historical origins of microbiome studies and methods for determining the ecological diversity of a microbial community. Next, it will introduce shotgun sequencing technologies such as metagenomics and metatranscriptomics, the computational challenges and methods associated with these data, and how they enable microbiome analysis. Finally, it will conclude with examples of the functional genomics of the human microbiome and its influences upon health and disease.

    Sediment erosion, transport, and deposition in fluvial systems are complex processes that are treated in detail in other sections of this book. Development of methods suitable for the collection of data that contribute to understanding these processes is a still-evolving science. Sediment and ancillary data are fundamental requirements for the proper management of river systems, including the design of structures, the determination of aspects of stream behavior, ascertaining the probable effect of removing an existing structure, estimation of bulk erosion, transport, and sediment delivery to the oceans, ascertaining the long-term usefulness of reservoirs and other public works, tracking movement of solid-phase contaminants, restoration of degraded or otherwise modified streams, and assistance in the calibration and validation of numerical models. This chapter presents techniques for measuring bed-material properties and suspended and bed-load discharges. Well-established and relatively recent, yet adequately tested, sampling equipment and methodologies, with designs that are guided by sound physical and statistical principles, are described. Where appropriate, the theory behind the development of the equipment and guidelines for its use are presented.

    In the past decade, quantum algorithms have been found which outperform the best classical solutions known for certain classical problems as well as the best classical methods known for simulation of certain quantum systems. This suggests that they may also speed up the simulation of some classical systems. I describe one class of discrete quantum algorithms which do so--quantum lattice-gas automata--and show how to implement them efficiently on standard quantum computers.

    Zimbelman, J. R.; Garry, W. B.; Bleacher, J. E.; Crown, D. A.

    2015-01-01

    Spacecraft exploration has revealed abundant evidence that Mars possesses some of the most dramatic volcanic landforms found anywhere within the solar system. How did a planet half the size of Earth produce volcanoes like Olympus Mons, which is several times the size of the largest volcanoes on Earth? This question is an example of the kinds of issues currently being investigated as part of the space-age scientific endeavor called "comparative planetology." This chapter summarizes the basic information currently known about volcanism on Mars. The volcanoes on Mars appear to be broadly similar in overall morphology (although, often quite different in scale) to volcanic features on Earth, which suggests that Martian eruptive processes are not significantly different from the volcanic styles and processes on Earth. Martian volcanoes are found on terrains of different age, and Martian volcanic rocks are estimated to comprise more than 50% of the Martian surface. This is in contrast to volcanism on smaller bodies such as Earth's Moon, where volcanic activity was mainly confined to the first half of lunar history (see "Volcanism on the Moon"). Comparative planetology supports the concept that volcanism is the primary mechanism for a planetary body to get rid of its internal heat; smaller bodies tend to lose their internal heat more rapidly than larger bodies (although, Jupiter's moon Io appears to contradict this trend; Io's intense volcanic activity is powered by unique gravitational tidal forces within the Jovian system; see "Volcanism on Io"), so that volcanic activity on Mars would be expected to differ considerably from that found on Earth and the Moon.

  14. Chapter 8: Biomass Pyrolysis Oils

    Energy Technology Data Exchange (ETDEWEB)

    McCormick, Robert L.; Baldwin, Robert M.; Arbogast, Stephen; Bellman, Don; Paynter, Dave; Wykowski, Jim

    2016-09-06

    Fast pyrolysis is heating on the order of 1000 degrees C/s in the absence of oxygen to 40-600 degrees C, which causes decomposition of the biomass. Liquid product yield from biomass can be as much as 80% of starting dry weight and contains up to 75% of the biomass energy content. Other products are gases, primarily carbon monoxide, carbon dioxide, and methane, as well as solid char and ash. Residence time in the reactor is only 0.5-2 s so that relatively small, low-capital-cost reactors can be used. The low capital cost combined with greenhouse gas emission reductions relative to petroleum fuels of 50-95% makes pyrolysis an attractive process. The pyrolysis liquids have been investigated as a refinery feedstock and as stand-alone fuels. Utilization of raw pyrolysis oil has proven challenging. The organic fraction is highly corrosive because of its high organic acid content. High water content lowers the net heating value and can increase corrosivity. It can be poorly soluble in petroleum or petroleum products and can readily absorb water. Distillation residues can be as high as 50%, viscosity can be high, oils can exhibit poor stability in storage, and they can contain suspended solids. The ignition quality of raw pyrolysis oils is poor, with cetane number estimates ranging from 0 to 35, but more likely to be in the lower end of that range. While the use of raw pyrolysis oils in certain specific applications with specialized combustion equipment may be possible, raw oils must be significantly upgraded for use in on-highway spark-ignition (SI) and compression-ignition (CI) engines. Upgrading approaches most often involve catalytic hydrodeoxygenation, one of a class of reactions known as hydrotreating or hydroprocessing. This chapter discusses the properties of raw and upgraded pyrolysis oils, as well as the potential for integrating biomass pyrolysis with a petroleum refinery to significantly reduce the hydroprocessing cost.

    This chapter explains the functional requirements of a concentrator photovoltaic (CPV) sun tracker. It derives the design specifications of a CPV tracker. The chapter presents taxonomy of trackers describing the most common tracking architectures, based on the number of axes, their relative position, and the foundation and placing of tracking drives. It deals with the structural issues related to tracker design, mainly related to structural flexure and its impact on the system's acceptance angle. The chapter analyzes the auto-calibrated sun tracking control, by describing the state of the art and its development background. It explores the sun tracking accuracy measurement with a practical example. The chapter discusses tracker manufacturing and tracker field works. It reviews survey of different types of tracker designs obtained from different manufacturers. Finally, the chapter deals with IEC62817, the technical standard developed for CPV sun trackers.

  17. Chapter 17: Estimating Net Savings: Common Practices

    Energy Technology Data Exchange (ETDEWEB)

    Violette, D. M.; Rathbun, P.

    2014-09-01

    This chapter focuses on the methods used to estimate net energy savings in evaluation, measurement, and verification (EM&V) studies for energy efficiency (EE) programs. The chapter provides a definition of net savings, which remains an unsettled topic both within the EE evaluation community and across the broader public policy evaluation community, particularly in the context of attribution of savings to particular program. The chapter differs from the measure-specific Uniform Methods Project (UMP) chapters in both its approach and work product. Unlike other UMP resources that provide recommended protocols for determining gross energy savings, this chapter describes and compares the current industry practices for determining net energy savings, but does not prescribe particular methods.

  18. Entanglement in Classical Optics

    CERN Document Server

    Ghose, Partha

    2013-01-01

    The emerging field of entanglement or nonseparability in classical optics is reviewed, and its similarities with and differences from quantum entanglement clearly pointed out through a recapitulation of Hilbert spaces in general, the special restrictions on Hilbert spaces imposed in quantum mechanics and the role of Hilbert spaces in classical polarization optics. The production of Bell-like states in classical polarization optics is discussed, and new theorems are proved to discriminate between separable and nonseparable states in classical wave optics where no discreteness is involved. The influence of the Pancharatnam phase on a classical Bell-like state is deived. Finally, to what extent classical polarization optics can be used to simulate quantum information processing tasks is also discussed. This should be of great practical importance because coherence and entanglement are robust in classical optics but not in quantum systems.

  1. Collagen XVIII/endostatin expression in experimental endotoxemic acute renal failure

    Directory of Open Access Journals (Sweden)

    M.C. Cichy

    2009-12-01

    Full Text Available Acute renal failure (ARF is a frequent complication of Gram-negative sepsis, with a high risk of mortality. Lipopolysaccharide (LPS-induced ARF is associated with hemodynamic changes that are strongly influenced by the overproduction of nitric oxide (NO through the cytokine-mediated up-regulation of inducible NO synthase. LPS-induced reductions in systemic vascular resistance paradoxically culminate in renal vasoconstriction. Collagen XVIII is an important component of the extracellular matrix expressed in basement membranes. Its degradation by matrix metalloproteases, cathepsins and elastases results in the formation of endostatin, claimed to have antiangiogenic activity and to be a prominent vasorelaxing agent. We evaluated the expression of endostatin/collagen XVIII in an endotoxemic ARF model. ARF was induced in C57BL/6 mice by intraperitoneal injection of LPS (10 mg/kg followed by sacrifice 4 and 12 h later. Kidney tissue was the source of RNA and protein and the subject of histological analysis. As early as 4 h after LPS administration, blood urea, creatinine and NO levels were significantly increased compared to control. Endostatin/collagen XVIII mRNA levels were 0.71 times lower than sham-inoculated mice 4 h after LPS inoculation, returning to normal levels 12 h after LPS inoculation. Immunohistological examination revealed that acute injury caused by LPS leads to an increase of endostatin basement membrane staining in association with the decrease of CD31 endothelial basement membrane staining. These results indicate that in the early phase of endotoxemic ARF the endostatin levels were not regulated by gene expression, but by the metabolism of collagen XVIII.

  2. Increased angiogenic response in aortic explants of collagen XVIII/endostatin-null mice.

    Science.gov (United States)

    Li, Qing; Olsen, Bjorn R

    2004-08-01

    Endostatin, a proteolytic fragment of basement membrane-associated collagen XVIII, has been shown to be a potent angiogenesis inhibitor both in vivo and in vitro when given at high concentrations. The precise molecular mechanisms by which it functions and whether or not it plays a role in physiological regulation of angiogenesis are not clear. In mice with targeted null alleles of Col18a1, there appears to be no major abnormality in vascular patterns or capillary density in most organs. Furthermore, the growth of experimental tumors is not increased. However, a detailed analysis of induced angiogenesis in these mice has not been performed. Therefore, we compared the angiogenic responses induced by in vitro culture of aortic explants from collagen XVIII/endostatin-null mice (ko) to wild-type (wt) littermates. We found a twofold increase in microvessel outgrowth in explants from ko mice, relative to wt explants. This increased angiogenesis was reduced to the wt level by the addition of low levels (0.1 microg/ml) of recombinant mouse or human endostatin during the culture period. To address cellular/molecular mechanisms underlying this difference in angiogenic response between ko and wt mice, we isolated endothelial cells from both strains and compared their biological behavior. Proliferation assays showed no difference between the two types of endothelial cells. In contrast, adhesion assays showed a striking difference in their ability to adhere to fibronectin suggesting that collagen XVIII/endostatin may regulate interactions between endothelial cells and underlying basement membrane-associated components, including fibronectin, such that in the absence of collagen XVIII/endostatin, endothelial cells are more adhesive to fibronectin. In the aortic explant assay, characterized by dynamic processes of microvessel elongation and regression, this may result in stabilization of newly formed vessels, reduced regression, and a net increase in microvessel outgrowth in

    We present a photometric study of the Andromeda XVIII dwarf spheroidal galaxy associated with M31, and situated well outside of the virial radius of the M31 halo. The galaxy was resolved into stars with Hubble Space Telescope/Advanced Camera for Surveys revealing the old red giant branch and red clump. With the new observational data we determined the Andromeda XVIII distance to be D = 1.33+-0.08 Mpc using the tip of red giant branch method. Thus, the dwarf is situated at the distance of 579 kpc from M31. We model the star formation history of Andromeda XVIII from the stellar photometry and Padova theoretical stellar isochrones. An ancient burst of star formation occurred 12-14 Gyr ago. There is no sign of recent/ongoing star formation in the last 1.5 Gyr. The mass fractions of the ancient and intermediate age stars are 34 and 66 per cent, respectively, and the total stellar mass is 4.2x10^6 Msun. It is probable that the galaxy has not experienced an interaction with M31 in the past. We also discuss star form...

I will start with a basic characterization of classical pragmatism; then, I shall examine certain conceptions in Peirce's and James' pragmatism, in order to establish affinities with Davidson´s thought. Finally, and bearing in mind the previous con-nections, I will reflect briefly on the relevance –often unrecognized- of classical pragmatist ideas in the context of contemporary philosophi-cal discussions.

  12. Classical And Quantum Chaos: Strongly Interacting Particles In A Confined Geometry

    Ivanushkin, P S

    2003-01-01

    This dissertation details the classical and quantum dynamics of two mechanical systems. The first one represents a charged particle confined inside a square elastic boundary acted on by a uniform magnetic field—the Square Magnetic Billiard. The second system, called the Circular Coulomb Billiard, consists of two particles, interacting by virtue of the Coulomb potential, and enclosed inside a circular boundary. One of the particles is considered to be massive and remains stationary. The first two chapters give a brief history of classical and quantum chaos, and review the major theoretical concepts. The third chapter analyzes the classical dynamics of the Square Magnetic Billiard. A number of approaches were used for numerical experiments: which shows that the system's classical behavior ranges from completely integrable to fully chaotic, but then the system restores it's integrability as the magnetic field continues to grow. The fourth chapter examines the Square Magnetic Billiard quantum mechanical...

    2013-01-01

    Full Text Available Recent studies have suggested that endogenous angiogenesis inhibitor endostatin/collagen XVIII might play an important role in the secondary brain injury following traumatic brain injury (TBI. In this study, we measured endostatin/collagen XVIII concentrations serially for 1 week after hospitalization by using the enzyme-linked immunosorbent assay method in the cerebrospinal fluid (CSF of 30 patients with TBI and a Glasgow Coma Scale (GCS score of 8 or less on admission. There was a significant trend toward increased CSF levels of endostatin after TBI versus control from 72 h after injury. In patients with GCS score of 3–5, CSF endostatin concentration was substantially higher at 72 h after injury than that in patients with GCS score of 6–8 (P<0.05 and peaked rapidly at day 5 after injury, but decreased thereafter. The CSF endostatin concentration in 12 patients with an unfavorable outcome was significantly higher than that in 18 patients with a favorable outcome at day 5 (P=0.043 and day 7 (P=0.005 after trauma. Receiver operating characteristic curve analysis suggested a reliable operating point for the 7-day CSF endostatin concentration predicting poor prognosis to be 67.29 pg/mL. Our preliminary findings provide new evidence that endostatin/collagen XVIII concentration in the CSF increases substantially in patients with sTBI. Its dynamic change may have some clinical significance on the judgment of brain injury severity and the assessment of prognosis. This trial is registered with the ClinicalTrials.gov Identifier: NCT01846546.

    Giachetta, Giovanni; Sardanashvily, Gennadi

    2009-01-01

    Contemporary quantum field theory is mainly developed as quantization of classical fields. Therefore, classical field theory and its BRST extension is the necessary step towards quantum field theory. This book aims to provide a complete mathematical foundation of Lagrangian classical field theory and its BRST extension for the purpose of quantization. Based on the standard geometric formulation of theory of nonlinear differential operators, Lagrangian field theory is treated in a very general setting. Reducible degenerate Lagrangian theories of even and odd fields on an arbitrary smooth manifold are considered. The second Noether theorems generalized to these theories and formulated in the homology terms provide the strict mathematical formulation of BRST extended classical field theory

    Human activities have greatly increased nitrogen emissions and deposition across large areas of Earth. Although nitrogen is an essential nutrient for plant growth, too much nitrogen in excess of critical loads leads to losses of biodiversity, soil and stream acidification, nutrient imbalances, and other deleterious effects. In a new report quantifying critical loads of nitrogen deposition across the United States, USGS scientist Steve Perakis and co-authors provided a chapter about responses of marine west coast forests. Much of this region is understudied with respect to nitrogen deposition, and in this chapter the authors identify known adverse effects and estimate critical loads of nitrogen deposition for western Oregon and Washington and southeast Alaska forests. Perakis also contributed to the synthesis chapter, which includes background, objectives, advantages and uncertainties of critical loads, an overview of critical loads across U.S. ecoregions, and other topics.

  19. Chapter 10: CPV Multijunction Solar Cell Characterization

    Energy Technology Data Exchange (ETDEWEB)

    Osterwald, Carl R.; Siefer, Gerald

    2016-04-15

    Characterization of solar cells can be divided into two types: the first is measurement of electrooptical semiconductor device parameters, and the second is determination of electrical conversion efficiency. This chapter reviews the multijunction concepts that are necessary for understanding Concentrator photovoltaic (CPV) cell characterization techniques, and describes how CPV efficiency is defined and used. For any I-V measurement of a multijunction cell, the sun simulator spectrum has to be adjusted in a way that all junctions generate the same photocurrent ratios with respect to each other as under reference conditions. The chapter discusses several procedures for spectral irradiance adjustments of solar simulators, essential for multijunction measurements. It overviews the light sources and optics commonly used in simulators for CPV cells under concentration. Finally, the chapter talks about the cell area, quantum efficiency (QE), and current-voltage (I-V) curve measurements that are needed to characterize cells as a function of irradiance.

It also includes a rather exhaustive description of the theory behind these methods. This high degree of detail is partly because previous publications of this theory contain errors, and partly because having done all this work it*s nice to have it written up in full somewhere, and being slightly beyond the thesis writing stage, this is only possible for me in a chapter like this.

Voltaire’s complex operation succeed in mobilizing public opinion and was resumed in the well known Traité sur la tolérance, an early example of the typical scheme of the affaire. Through the analysis of the public opinion in France during the XVIII century, we will demonstrate the ambivalence of Voltaire’s thoughts in relation to this concept: one one side reign of the irrationality, when linked to the local reality, on the other, source of truth when enlightened and universal.

    Full Text Available En este artículo se plantea una aproximación a las luchas por el control y el acceso al agua entre las élites regionales hispanas y criollas y los pueblos de indios de la jurisdicción de Tula, durante el siglo XVIII. Una lucha que, en definitiva, hundía sus raíces en las nuevas perspectivas económicas regionales, provocadas por el descenso de la actividad ganadera. De esta manera, hacia el siglo XVIII la economía regional volteó la mirada hacia el cultivo de granos, sin dejar de lado la cría de ganado para las matanzas. Dentro de este contexto, las élites regionales, antiguas propietarias de grandes hatos de ganado, invirtieronimportantes capitales en la construcción de una infraestructura hidráulica (zanjas, presas, jagüeyes, encaminada al riego de los cultivos. Sin embargo, eran los pueblos indios quienes desde antaño habían controlado una parte importante de los recursos hídricos disponibles, por lo cual la confrontación fue el resultado inevitable del proceso.

    Full Text Available At the beginning of the 18th Century the indigenous people of Lima were accorded permission to celebrate the Spanish kings in a segregated group. The criollo elites expected them to represent their old kings in the demostrations, thus taking part in the exaltation of the Peruvian history. The descriptions of the limeño festivities, which show that the costumes of the Incas in the masquerades were highly hibridisized and baroque, allow us to analyse the characteristics of the Inca renaissance in the 18th Century. The costume played a basic role in the rehabilitation of the old Peruvian kings in the Colonial society.

    Al principio del siglo XVIII, se les otorgó a los indios de Lima la posibilidad de festejar a los monarcas españoles en grupo aparte. De ellos se esperaba que representasen a sus antiguos monarcas en desfiles o mascaradas y participaran por consiguiente, animados por las elites criollas, en la exaltación de la historia peruana. Fuertemente mestizada y apropiada a los gustos barrocos, la indumentaria de los incas de las mascaradas descrita en las relaciones de fiestas limeñas nos permite analizar las características del renacimiento incaico del siglo XVIII y ver cómo la vestimenta desempañaba un papel fundamental en la rehabilitación de los antiguos monarcas peruanos en la sociedad colonial.

    Full Text Available The expansion of the ideal of religious tolerance in 18th century Europe was not the exclusive work of deists or atheists. Many Christians then argued that intolerance was contrary to the Gospel and the spirit of the early centuries of the Church. The censorship of the Inquisition and the absence of religious minorities prevented the discussions on tolerance taking place in countries such as France or Austria from occurring south of the Pyrenees. Even so, Christian arguments in favour of religious freedom appeared, albeit stealthily, in 18th century Spain and were reflected in the texts of some Spanish reformers.La expansión del ideal de tolerancia religiosa en la Europa del siglo XVIII no fue obra exclusiva de deístas o ateos. Muchos cristianos defendieron por entonces que la intolerancia era contraria al Evangelio y al espíritu de los primeros siglos de la Iglesia. La labor censoria de la Inquisición y la ausencia de minorías religiosas impidieron que los debates sobre la tolerancia desarrollados en países como Francia o Austria se reprodujeran al sur de los Pirineos. Aun así, los argumentos cristianos en favor de la libertad religiosa entraron, aunque fuese a hurtadillas, en la España del siglo XVIII y se reflejaron en los textos de algunos reformistas españoles.

  4. Discrete Classical Electromagnetic Fields

    CERN Document Server

    De Souza, M M

    1997-01-01

    The classical electromagnetic field of a spinless point electron is described in a formalism with extended causality by discrete finite transverse point-vector fields with discrete and localized point interactions. These fields are taken as a classical representation of photons, ``classical photons". They are all transversal photons; there are no scalar nor longitudinal photons as these are definitely eliminated by the gauge condition. The angular distribution of emitted photons coincides with the directions of maximum emission in the standard formalism. The Maxwell formalism and its standard field are retrieved by the replacement of these discrete fields by their space-time averages, and in this process scalar and longitudinal photons are necessarily created and added. Divergences and singularities are by-products of this averaging process. This formalism enlighten the meaning and the origin of the non-physical photons, the ones that violate the Lorentz condition in manifestly covariant quantization methods.

  5. Between classical and quantum

    Landsman, N P

    2005-01-01

    The relationship between classical and quantum theory is of central importance to the philosophy of physics, and any interpretation of quantum mechanics has to clarify it. Our discussion of this relationship is partly historical and conceptual, but mostly technical and mathematically rigorous, including over 500 references. On the assumption that quantum mechanics is universal and complete, we discuss three ways in which classical physics has so far been believed to emerge from quantum physics, namely in the limit h -> 0 of small Planck's constant (in a finite system), in the limit of a large system, and through decoherence and consistent histores. The first limit is closely related to modern quantization theory and microlocal analysis, whereas the second involves methods of C*-algebras and the concepts of superselection sectors and macroscopic observables. In these limits, the classical world does not emerge as a sharply defined objective reality, but rather as an approximate appearance relative to certain "...

  6. Randomness: Quantum versus classical

    Science.gov (United States)

    Khrennikov, Andrei

    2016-05-01

    Recent tremendous development of quantum information theory has led to a number of quantum technological projects, e.g. quantum random generators. This development had stimulated a new wave of interest in quantum foundations. One of the most intriguing problems of quantum foundations is the elaboration of a consistent and commonly accepted interpretation of a quantum state. Closely related problem is the clarification of the notion of quantum randomness and its interrelation with classical randomness. In this short review, we shall discuss basics of classical theory of randomness (which by itself is very complex and characterized by diversity of approaches) and compare it with irreducible quantum randomness. We also discuss briefly “digital philosophy”, its role in physics (classical and quantum) and its coupling to the information interpretation of quantum mechanics (QM).

    This book guides undergraduate students in the use of Maxima—a computer algebra system—in solving problems in classical mechanics. It functions well as a supplement to a typical classical mechanics textbook. When it comes to problems that are too difficult to solve by hand, computer algebra systems that can perform symbolic mathematical manipulations are a valuable tool. Maxima is particularly attractive in that it is open-source, multiple-platform software that students can download and install free of charge. Lessons learned and capabilities developed using Maxima are easily transferred to other, proprietary software.

    2010-01-01

    We show how to enlarge the covariance group of any classical field theory in such a way that the resulting "covariantized" theory is 'essentially equivalent' to the original. In particular, our technique will render any classical field theory generally covariant, that is, the covariantized theory will be spacetime diffeomorphism-covariant and free of absolute objects. Our results thus generalize the well-known parametrization technique of Dirac and Kucha\\v{r}. Our constructions apply equally well to internal covariance groups, in which context they produce natural derivations of both the Utiyama minimal coupling and St\\"uckelberg tricks.

    2016-01-01

    In this work, we introduce classical holographic codes. These can be understood as concatenated probabilistic codes and can be represented as networks uniformly covering hyperbolic space. In particular, classical holographic codes can be interpreted as maps from bulk degrees of freedom to boundary degrees of freedom. Interestingly, they are shown to exhibit features similar to those expected from the AdS/CFT correspondence. Among these are a version of the Ryu-Takayanagi formula and intriguing properties regarding bulk reconstruction and boundary representations of bulk operations. We discuss the relation of our findings with expectations from AdS/CFT and, in particular, with recent results from quantum error correction.

  15. Metrology of Large Parts. Chapter 5

    Science.gov (United States)

    Stahl, H. Philip

    2012-01-01

    As discussed in the first chapter of this book, there are many different methods to measure a part using optical technology. Chapter 2 discussed the use of machine vision to measure macroscopic features such as length and position, which was extended to the use of interferometry as a linear measurement tool in chapter 3, and laser or other trackers to find the relation of key points on large parts in chapter 4. This chapter looks at measuring large parts to optical tolerances in the sub-micron range using interferometry, ranging, and optical tools discussed in the previous chapters. The purpose of this chapter is not to discuss specific metrology tools (such as interferometers or gauges), but to describe a systems engineering approach to testing large parts. Issues such as material warpage and temperature drifts that may be insignificant when measuring a part to micron levels under a microscope, as will be discussed in later chapters, can prove to be very important when making the same measurement over a larger part. In this chapter, we will define a set of guiding principles for successfully overcoming these challenges and illustrate the application of these principles with real world examples. While these examples are drawn from specific large optical testing applications, they inform the problems associated with testing any large part to optical tolerances. Manufacturing today relies on micrometer level part performance. Fields such as energy and transportation are demanding higher tolerances to provide increased efficiencies and fuel savings. By looking at how the optics industry approaches sub-micrometer metrology, one can gain a better understanding of the metrology challenges for any larger part specified to micrometer tolerances. Testing large parts, whether optical components or precision structures, to optical tolerances is just like testing small parts, only harder. Identical with what one does for small parts, a metrologist tests large parts and optics

  16. Strong Coupling and Classicalization

    CERN Document Server

    Dvali, Gia

    2016-01-01

    Classicalization is a phenomenon in which a theory prevents itself from entering into a strong-coupling regime, by redistributing the energy among many weakly-interacting soft quanta. In this way, the scattering process of some initial hard quanta splits into a large number of soft elementary processes. In short, the theory trades the strong coupling for a high-multiplicity of quanta. At very high energies, the outcome of such a scattering experiment is a production of soft states of high occupation number that are approximately classical. It is evident that black hole creation in particle collision at super-Planckian energies is a result of classicalization, but there is no a priory reason why this phenomenon must be limited to gravity. If the hierarchy problem is solved by classicalization, the LHC has a chance of detecting a tower of new resonances. The lowest-lying resonances must appear right at the strong coupling scale in form of short-lived elementary particles. The heavier members of the tower must b...

    Bacterial kidney disease (BKD) of salmonid fishes, caused by Renibacterium salmoninarum, has been recognized as a serious disease in salmonid fishes since the 1930s. This chapter discusses the occurrence and significance, etiology, and pathogenesis of BKD. It then describes the different vaccination procedures and the effects and side-effects of vaccination. Despite years of research, however, only a single vaccine has been licensed for prevention of BKD, and has demonstrated variable efficacy. Therefore, in addition to a presentation of the current status of BKD vaccination, a discussion of potential future directions for BKD vaccine development is included in the chapter. This discussion is focused on the unique characteristics of R. salmoninarum and its biology, as well as aspects of the salmonid immune system that might be explored specifically to develop more effective vaccines for BKD prevention.

    Oda, Ichiro

    2016-01-01

    We study various classical aspects of the Weyl transverse (WTDiff) gravity in a general space-time dimension. First of all, we clarify a classical equivalence among three kinds of gravitational theories, those are, the conformally-invariant scalar tensor gravity, Einstein's general relativity and the WTDiff gravity via the gauge fixing procedure. Secondly, we show that in the WTDiff gravity the cosmological constant is a mere integration constant as in unimodular gravity, but it does not receive any radiative corrections unlike the unimodular gravity. A key point in this proof is to construct a covariantly conserved energy-momentum tensor, which is achieved on the basis of this equivalence relation. Thirdly, we demonstrate that the Noether current for the Weyl transformation is identically vanishing, thereby implying that the Weyl symmetry existing in both the conformally-invariant scalar tensor gravity and the WTDiff gravity is a "fake" symmetry. We find it possible to extend this proof to all matter fields,...

    De Souza, M M

    1995-01-01

    The problems of Classical Electrodynamics with the electron equation of motion and with non-integrable singularity of its self-field stress tensor are well known. They are consequences, we show, of neglecting terms that are null off the charge world line but that gives a non null contribution on its world line. The self-field stress tensor of a point classical electron is integrable, there is no causality violation and no conflict with energy conservation in its equation of motion, and there is no need of any kind of renormalization nor of any change in the Maxwell's theory for this. (This is part of the paper hep-th/9510160, stripped , for simplicity, of its non-Minkowskian geometrization of causality and of its discussion about the physical meaning of the Maxwell-Faraday concept of field).

The bibliography analysis indicated that technical and esthetical demands lead to a practice of non-anatomical movements, causing the ballet dancer to suffer from a number of associated lesions. Most of the injuries are caused by technical mistakes and wrong training. Troubles in children are usually due to trying to force external rotation at hip level and to undue use of point ballet slippers. The commonest lesions are in feet and ankles, followed by knees and hips. The rarest ones are in the upper limbs. These injuries are caused by exercise excess, by repetitions always in the same side and by wrong and early use of point slippers. The study reached the conclusion that incorrect application of classical ballet technique predisposes the dancers to characteristic injuries.

  12. Classical and statistical thermodynamics

    CERN Document Server

    Rizk, Hanna A

    2016-01-01

    This is a text book of thermodynamics for the student who seeks thorough training in science or engineering. Systematic and thorough treatment of the fundamental principles rather than presenting the large mass of facts has been stressed. The book includes some of the historical and humanistic background of thermodynamics, but without affecting the continuity of the analytical treatment. For a clearer and more profound understanding of thermodynamics this book is highly recommended. In this respect, the author believes that a sound grounding in classical thermodynamics is an essential prerequisite for the understanding of statistical thermodynamics. Such a book comprising the two wide branches of thermodynamics is in fact unprecedented. Being a written work dealing systematically with the two main branches of thermodynamics, namely classical thermodynamics and statistical thermodynamics, together with some important indexes under only one cover, this treatise is so eminently useful.

  13. Randomness: quantum versus classical

    CERN Document Server

    Khrennikov, Andrei

    2015-01-01

    Recent tremendous development of quantum information theory led to a number of quantum technological projects, e.g., quantum random generators. This development stimulates a new wave of interest in quantum foundations. One of the most intriguing problems of quantum foundations is elaboration of a consistent and commonly accepted interpretation of quantum state. Closely related problem is clarification of the notion of quantum randomness and its interrelation with classical randomness. In this short review we shall discuss basics of classical theory of randomness (which by itself is very complex and characterized by diversity of approaches) and compare it with irreducible quantum randomness. The second part of this review is devoted to the information interpretation of quantum mechanics (QM) in the spirit of Zeilinger and Brukner (and QBism of Fuchs et al.) and physics in general (e.g., Wheeler's "it from bit") as well as digital philosophy of Chaitin (with historical coupling to ideas of Leibnitz). Finally, w...

  14. Computation in Classical Mechanics

    Timberlake, Todd

    2007-01-01

    There is a growing consensus that physics majors need to learn computational skills, but many departments are still devoid of computation in their physics curriculum. Some departments may lack the resources or commitment to create a dedicated course or program in computational physics. One way around this difficulty is to include computation in a standard upper-level physics course. An intermediate classical mechanics course is particularly well suited for including computation. We discuss the ways we have used computation in our classical mechanics courses, focusing on how computational work can improve students' understanding of physics as well as their computational skills. We present examples of computational problems that serve these two purposes. In addition, we provide information about resources for instructors who would like to include computation in their courses.

    Full Text Available Los cabildos de Antioquia, durante el siglo xviii, instaban a los habitantes de ciudades y villas a matar los cerdos callejeros. Este rasgo de violencia permite acercarse a la confrontación cotidiana entre la élite y los criadores de cerdos, un grupo social bajo. Los cabildos defendían un modelo de civilidad basado en estrategias de control social impulsadas por la administración borbónica. Los criadores de puercos, pobres en su mayoría, actuaban como colectivo defendiendo esta actividad, de donde obtenían unos pesos para subsistir. Con el frecuente ataque a los cerdos urbanos, y a sus dueños, la élite quiso impedir que ese sector de pobres adquiriera independencia económica, pues convenía sujetarlos, ocupando su mano de obra en labores mineras, agrícolas y ganaderas.

    Full Text Available This article will talk about the child in society of Hetman – the autonomous entity within the Russian Empire, which was rapidly losing the remnants of autonomy in the second half of the XVIII century, subjecting to the desire of the center to modernize and unify its border territory. Such interaction of traditions and innovations influenced the public's worldview and determined the attitude to the family, marriage, child. These topics are still relatively poorly studied in the Ukrainian material, particularly the problems of childhood. The studies of actually "little man" in Ukraine of XVIII century are made virtually from a clean slate and at the beginning it is necessary to determine whom society is considered as a child, and also when the childhood is ended. This issue is harder than it seems at first glance, because the society of Hetmanate in relation to children was guided by the stratagem of folk traditions, religious norms, the "old" law (the Lithuanian Statute, the Magdeburg right and sachsenspiegel inherited from the Commonwealth and the "new" laws of the Russian Empire. They determined the age of adulthood in different ways, when the individual became a child and was no longer to be, as well as the criteria of those age limits. It is important that the legal mechanisms of age-identification included in the action in the case of judicial proceedings, property disputes, marital conflicts. On a daily level, the perception of childhood and maturity depended on the combination of external features of an individual (body type, facial features, etc., conduct, and perform social roles. A huge role is played the institution of marriage, act of which was probably the most important and revealing marker of the fact that the kid finally became an adult.

Con este propósito se han revisado los niveles de acuñación, especialmente los de moneda menuda, porque esta era la que circulaba en los mercados cotidianamente y se usaba para fijar los precios de los comestibles, así como para pagar los jornales de los trabajadores en la ciudad de Santiago a fines del siglo XVIII y comienzos del siglo XIX. Esto quiere decir que la gente común conocía el dinero y lo utilizaba para pagar sus transacciones cotidianas, lo que a su vez implicaría que la economía chilena estaba creciendo y conformando un mercado con sus propias características.The object of this article is to illustrate that during the second half of the eighteenth century monetary circulation was much more active in Santiago than had been previously thought. To that end minting levels have been analyzed especially the volume of small change as this was the currency that circulated in the daily market and was used to fix the price of foodstuffs as well as to pay daily wages in the city of Santiago during the late eighteenth and the early nineteenth century. This means that common people knew about and used money in their daily transactions and also implies that the Chilean economy was growing and forming a market of its own.

    Theories of autobiographical memory posit that extended time periods (here termed chapters) and memories are organised hierarchically. If chapters organise memories and guide their recall, then chapters and memories should show similar temporal distributions over the life course. Previous research...... demonstrates that positive but not negative memories show a reminiscence bump and that memories cluster at the beginning of extended time periods. The current study tested the hypotheses that (1) ages marking the beginning of positive but not negative chapters produce a bump, and that (2) specific memories...... are over-represented at the beginning of chapters. Potential connections between chapters and the cultural life script are also examined. Adult participants first divided their life story into chapters and identified their most positive and most negative chapter. They then recalled a specific memory from...

    Types XV and XVIII collagen belong to a unique and novel subclass of the collagen superfamily for which the authors have proposed the name the MULTIPLEXIN family. Members of this class contain polypeptides with multiple triple-helical domains separated and flanked by non-triple-helical regions. In this paper, they report the isolation of human cDNAs and genomic DNAs encoding the [alpha]1 (XVIII) collagen chain. Utilizing a genomic clone as probe, they have mapped the COL18A1 gene to chromosome 21q22.3 by fluorescence in situ hybridization. In addition, using an interspecific backcross panel, they have shown that the murine Col18a1 locus is on chromosome 10, close to the loci for Col6a1 and Col6a2. 16 refs., 5 figs.

As an example, we take this analogy to any generic second order Lagrangian and exactly derive the trace anomaly relation suggested by Duff. This indicates that an intrinsic reason for the existence of such a relation sh...

    Full Text Available We show that the thermodynamics of ideal gases may be derived solely from the Democritean concept of corpuscles moving in vacuum plus a principle of simplicity, namely that these laws are independent of the laws of motion, aside from the law of energy conservation. Only a single corpuscle in contact with a heat bath submitted to a z and t-invariant force is considered. Most of the end results are known but the method appears to be novel. The mathematics being elementary, the present paper should facilitate the understanding of the ideal gas law and of classical thermodynamics even though not-usually-taught concepts are being introduced.

    Rosenfeld, Taylor; Webster, John; Garg, Sanjay

    2009-01-01

    The previous chapters have focused on the requirements for sensors and actuators for "More Intelligent Gas Turbine Engines" from the perspective of performance and operating environment. Even if a technology is available, which meets these performance requirements, there are still various hurdles to be overcome for the technology to transition into a real engine. Such requirements relate to TRL (Technology Readiness Level), durability, reliability, volume, weight, cost, etc. This chapter provides an overview of such universal requirements which any sensor or actuator technology will have to meet before it can be implemented on a product. The objective here is to help educate the researchers or technology developers on the extensive process that the technology has to go through beyond just meeting performance requirements. The hope is that such knowledge will help the technology developers as well as decision makers to prevent wasteful investment in developing solutions to performance requirements, which have no potential to meet the "universal" requirements. These "universal" requirements can be divided into 2 broad areas: 1) Technology value proposition; and 2) Technology maturation. These requirements are briefly discussed in the following.

    Petroleum hydrocarbons and fuel oxygenates are among the most commonly occurring and widely distributed contaminants in the environment. This chapter presents a summary of the sources, transport, fate, and remediation of volatile fuel hydrocarbons and fuel additives in the environment. Much research has focused on the transport and transformation processes of petroleum hydrocarbons and fuel oxygenates, such as benzene, toluene, ethylbenzene, and xylenes and methyl tert‐butyl ether, in groundwater following release from underground storage tanks. Natural attenuation from biodegradation limits the movement of these contaminants and has received considerable attention as an environmental restoration option. This chapter summarizes approaches to environmental restoration, including those that rely on natural attenuation, and also engineered or enhanced remediation. Researchers are increasingly combining several microbial and molecular-based methods to give a complete picture of biodegradation potential and occurrence at contaminated field sites. New insights into the fate of petroleum hydrocarbons and fuel additives have been gained by recent advances in analytical tools and approaches, including stable isotope fractionation, analysis of metabolic intermediates, and direct microbial evidence. However, development of long-term detailed monitoring programs is required to further develop conceptual models of natural attenuation and increase our understanding of the behavior of contaminant mixtures in the subsurface.

  6. Chapter 44: history of neurology in Italy.

    Science.gov (United States)

    Bentivoglio, Marina; Mazzarello, Paolo

    2010-01-01

    The chapter starts from the Renaissance (although the origins of Italian neurology can be traced back to the Middle Ages), when treatises of nervous system physiopathology still followed Hippocratic and Galenic "humoral" theories. In Italy, as elsewhere in Europe, the concepts of humoral pathology were abandoned in the 18th century, when neurology was influenced by novel trends. Neurology acquired the status of clinical discipline (as "clinic of mental diseases") after national reunification (declared in 1861 but completed much later). At the end of the 19th and first decades of the 20th century, eminent Italian "neuropsychiatrists" (including, among many others, Ugo Cerletti, who introduced electroconvulsive shock therapy in 1938) stimulated novel knowledge and approaches, "centers of excellence" flourished, and "Neurological Institutes" were founded. In the first half of the 20th century, the history of Italian neurology was dominated by World Wars I and II (which stimulated studies on the wounded) and the fascist regime in-between the Wars (when the flow of information was instead very limited). Italy became a republic in 1946, and modern neurology and its distinction from psychiatry were finally promoted. The chapter also provides detailed accounts of scientific societies and journals dedicated to the neurological sciences in Italy.

    A classical model of the Schrodinger's wave packet is considered. The problem of finding the energy levels corresponds to a classical manipulation game. It leads to an approximate but non-perturbative method of finding the eigenvalues, exploring the bifurcations of classical trajectories. The role of squeezing turns out decisive in the generation of the discrete spectra.

    Full Text Available Syphilis is a sexually or congenitally transmitted infectious disease with an impact on the health of human populations that has undergone important cycles in different countries and periods of history. Its presence was first diagnosed in Europe in the late XIV century. In Portugal, although there are various written records of the infection in the last centuries, there are rare references to it in archeological findings (mummified bodies are also rare in Portugal. The current study describes a probable case of congenital syphilis in an 18-month-old girl buried in the Church of the Sacrament in Lisbon. Her body, dating to the XVIII century, was found mummified together with dozens of others, still not studied. Symmetrical periostitis of the long bones, osteitis, metaphyseal lesions, left knee articular, and epiphyseal destruction, and a rarefied lesion with a radiological appearance compatible with Wimberger's sign all point to a diagnosis of congenital syphilis. The diagnosis of this severe form of the infection, possibly related to the cause of death in this upper-class girl, calls attention to the disease's presence in XVIII century Lisbon and is consistent with the intense mobilization at the time in relation to the risks posed by so-called heredosyphilis. It is the first case of congenital syphilis in a child reported in archeological findings in Portugal, and can be correlated with other cases in skeletons of adults buried in cemeteries in Lisbon (in the XVI to XVIII centuries and Coimbra (XIX century. Finally, this finding highlights the need to study the entire series of mummified bodies in the Church of the Sacrament in order to compare the paleopathological findings and existing historical documents on syphilis, so as to expand the paleoepidemiological knowledge of this infection in XVIII century Lisbon.

    Full Text Available XVII. century corresponds to a period called“Middle Classic Period” by literature historians, a periodwhere the Classic Turkish poetry was at the peak of itsmaturity. This period is also interesting, because it is aperiod that contains different styles/tastes feeding fromthe same source in Turkish poetry. It is a well known factthat until the XVII. century, there wasn’t a seriousseparation between the words and meaning in ClassicTurkish poetry, and some poets were considered betterthan the others by personal preferences, but this hasnever became a generally accepted idea. However,especially at the end of the XVI. century and beginning ofthe XVII. century, with the effect of Sebk-i Hindi, firstseen in Iran, India and then Divan poetry and based onhidden, concealed and complex meaning, some importantchanges were seen in the meaning domain of Turkishpoetry. In the same century, a new formation calledHikemi Tarz, known as Nabi school and prioritizesthoughts and wisdom in poetry, has shown its effect inliterature history. This new style was also based on themeaning like Sebk-i Hindi, but was interested in theconcrete side of the meaning; in other words thoughts.The poets influenced by this new style have opened a newwindow in classic poetry and tried to enrich the meaningdimension of poetry by thought axis. In this paper, the changes and developments inthe meaning domain of Turkish poetry caused by Classicstyle, Sebk-i Hindi, Hikemi Tarz and Localization poetry,seem on classic Turkish poetry in the XVII. and XVIII.centuries, will tried to be examined in sample versestaken from the poems of the poets representing thoseperiods.

    Full Text Available Este ensayo observa las insurrecciones populares del siglo XVIII no como episodios casuales o aislados, sino como síntomas de un sentimiento generalizado de descontento social e intensificado conflicto. Sentimientos cuya intensidad se incrementó durante la segunda mitad del siglo XVIII y culminó con la Gran Rebelión de 1780-1783 en el sur de los Andes, el levantamiento en Quito de 1765 y la Rebelión de los Comuneros en la Nueva Granada de 1781. Este artículo examina los trabajos que hacen referencia a estas revueltas, reconociendo el hecho que la producción académica de las insurrecciones de finales del siglo XVIII en las colonias americanas forman parte de los amplios debates académicos que abordan las insurrecciones fuera del contexto Andino, e incorpora preguntas promulgadas por los estudiosos de las revueltas campesinas y el conflicto armado en otros campos y otros periodos.

    Full Text Available With this essay we wish to contribute to the historical recuperation of our musical and cultural heritage with particular reference to one specific case. It will, therefore, describe the musical activity from 1700 to 1750 of the Cathedral Musical Chapel of La Seu d'Urgell which had been a particularly relevant centre ever since the Middle Ages for its importance as a frontier pass on the Pyrenees between France and Spain. There do exist certain historical studies of the Medieval and Renaissance periods that led to publications by Higini Anglés analyzing the figure of Joan Brudieu. But, on the other hand, very little is known about the musical life of that "Episcopal" town during the XVIII to XX centuries (recently being the bishop of La Seu also the prince of Andorra, all together with the President of the French Republic. Taking up where the work of Pedrell-Anglés had left off, this essay initiates the systematic compilation of whatever information concerning music is contained in the Cathedral Archives. Though it is our intention to continue our line of study, on this occasion we are only going to publish the Chapter Acts from the period 1700-1750, which will permit us to form a general idea about the activities and the repercussions of one of the principal Musical Chapel in Catalonia, and also of one of the centres in the Hispanic sphere of influence that Musicology has least studied until recently.

  20. Perspective: Quantum or classical coherence?

    Science.gov (United States)

    Miller, William H

    2012-06-07

    Some coherence effects in chemical dynamics are described correctly by classical mechanics, while others only appear in a quantum treatment--and when these are observed experimentally it is not always immediately obvious whether their origin is classical or quantum. Semiclassical theory provides a systematic way of adding quantum coherence to classical molecular dynamics and thus provides a useful way to distinguish between classical and quantum coherence. Several examples are discussed which illustrate both cases. Particularly interesting is the situation with electronically non-adiabatic processes, where sometimes whether the coherence effects are classical or quantum depends on what specific aspects of the process are observed.

  2. Grassmannization of classical models

    Pollet, Lode; Prokof'ev, Nikolay V; Svistunov, Boris V

    2016-01-01

    Applying Feynman diagrammatics to non-fermionic strongly correlated models with local constraints might seem generically impossible for two separate reasons: (i) the necessity to have a Gaussian (non-interacting) limit on top of which the perturbative diagrammatic expansion is generated by Wick's theorem, and (ii) the Dyson's collapse argument implying that the expansion in powers of coupling constant is divergent. We show that for arbitrary classical lattice models both problems can be solved/circumvented by reformulating the high-temperature expansion (more generally, any discrete representation of the model) in terms of Grassmann integrals. Discrete variables residing on either links, plaquettes, or sites of the lattice are associated with the Grassmann variables in such a way that the partition function (and correlations) of the original system and its Grassmann-field counterpart are identical. The expansion of the latter around its Gaussian point generates Feynman diagrams. A proof-of-principle implement...

    This comprehensive textbook is devoted to classical and quantum cosmology, with particular emphasis on modern approaches to quantum gravity and string theory and on their observational imprint. It covers major challenges in theoretical physics such as the big bang and the cosmological constant problem. An extensive review of standard cosmology, the cosmic microwave background, inflation and dark energy sets the scene for the phenomenological application of all the main quantum-gravity and string-theory models of cosmology. Born of the author's teaching experience and commitment to bridging the gap between cosmologists and theoreticians working beyond the established laws of particle physics and general relativity, this is a unique text where quantum-gravity approaches and string theory are treated on an equal footing.

    Full Text Available BACKGROUND: The impact of a scientific article is proportional to the citations it has received. In this study, we set out to identify the most cited works in epileptology in order to evaluate research trends in this field. METHODS: According to the Web of Science database, articles with more than 400 citations qualify as "citation classics". We conducted a literature search on the ISI Web of Science bibliometric database for scientific articles relevant to epilepsy. RESULTS: We retrieved 67 highly cited articles (400 or more citations, which were published in 31 journals: 17 clinical studies, 42 laboratory studies, 5 reviews and 3 classification articles. Clinical studies consisted of epidemiological analyses (n=3, studies on the clinical phenomenology of epilepsy (n=5 – including behavioral and prognostic aspects – and articles focusing on pharmacological (n=6 and non-pharmacological (n=3 treatment. The laboratory studies dealt with genetics (n=6, animal models (n=27, and neurobiology (n=9 – including both neurophysiology and neuropathology studies. The majority (61% of citation classics on epilepsy were published after 1986, possibly reflecting the expansion of research interest in laboratory studies driven by the development of new methodologies, specifically in the fields of genetics and animal models. Consequently, clinical studies were highly cited both before and after the mid 80s, whilst laboratory researches became widely cited after 1990. CONCLUSIONS: Our study indicates that the main drivers of scientific impact in the field of epileptology have increasingly become genetic and neurobiological studies, along with research on animal models of epilepsy. These articles are able to gain the highest numbers of citations in the time span of a few years and suggest potential directions for future research.

  5. Chapter 40: history of neurology in France.

    2010-01-01

    The history of neurology in France is characterized by the very high degree of centralization in that country where "everything seems to happen in Paris," and yet the considerable degree of autonomous diversity in the evolution of some other medical schools such as Montpellier and Strasbourg. It could be argued that France saw the birth of clinical neurology as a separate discipline since Jean Martin Charcot at the Salpêtrière Hospital obtained a chair of diseases of the nervous system in 1892, a first in the history of the academic world. The chapter shows, however, that the work of Charcot was preceded by a long evolution in medical thinking, which culminated with the introduction of experimental medicine developed by Claude Bernard and François Magendie, and by the study of aphasia by Paul Broca and its localization of language in a specific area of the brain. Many of the great neurologists of France like Duchenne de Boulogne, Gilles de la Tourette, Joseph Babinski and Pierre Marie gravitated around Charcot while others like Charles-Edward Brown-Sequard and Jules Dejerine developed their talents independently. The history of Sainte-Anne Hospital further illustrates this independence. It also shows the relation between neurology and psychiatry with Henri Ey, Jean Delay and Pierre Deniker, who collaborated with Henri Laborit in the clinical development of chlorpromazine. Sainte Anne also saw the birth of modern neuropsychology with Henry Hécaen. Jean Talairach and his group developed human stereotaxic neurosurgery and a 3-dimensional brain atlas that is used around the world. The chapter also mentions institutions (the CNRS and INSERM) that have contributed to developments partially independently from medical schools. It concludes with a presentation of schools located outside of Paris that have played a significant role in the development of neurology. Six of the most important ones are described: Montpellier, Toulouse, Bordeaux, Strasbourg, Lyon, and

    Apart from mercury itself, coal rank and halogen content are among the most important factors inherent in coal that determine the proportion of mercury captured by conventional controls during coal combustion. This chapter reviews how mercury in coal occurs, gives available concentration data for mercury in U.S. and international commercial coals, and provides an overview of the natural variation in halogens that influence mercury capture. Three databases, the U.S. Geological Survey coal quality (USGS COALQUAL) database for in-ground coals, and the 1999 and 2010 U.S. Environmental Protection Agency (EPA) Information Collection Request (ICR) databases for coals delivered to power stations, provide extensive results for mercury and other parameters that are compared in this chapter. In addition to the United States, detailed characterization of mercury is available on a nationwide basis for China, whose mean values in recent compilations are very similar to the United States in-ground mean of 0.17 ppm mercury. Available data for the next five largest producers (India, Australia, South Africa, the Russian Federation, and Indonesia) are more limited and with the possible exceptions of Australia and the Russian Federation, do not allow nationwide means for mercury in coal to be calculated. Chlorine in coal varies as a function of rank and correspondingly, depth of burial. As discussed elsewhere in this volume, on a proportional basis, bromine is more effective than chlorine in promoting mercury oxidation in flue gas and capture by conventional controls. The ratio of bromine to chlorine in coal is indicative of the proportion of halogens present in formation waters within a coal basin. This ratio is relatively constant except in coals that have interacted with deep-basin brines that have reached halite saturation, enriching residual fluids in bromine. Results presented here help optimize mercury capture by conventional controls and provide a starting point for

El trabajo está realizado, especialmente, en base a la documentación existente en el Archivo Histórico Municipal de Almagro, estudiándose la situación de la enseñanza primaria religiosa y seglar, así como la superior y universitaria. La enseñanza primaria religiosa estuvo dirigida básicamente por los jesuítas, que trataron pronto de sustraerse a la obligación contraída con el Ayuntamiento, cuando llegaron a Almagro; Íes relevaron en dicha obligación los hermanos hospitalarios de San Juan de Dios, que estaban muy necesitados de ayuda económica, por lo que aceptaron regentar las escuelas primarias. La enseñanza seglar estuvo a cargo de maestros, que en la mayoría de los casos ejercían sin titulación alguna, generando un evidente intrusismo profesional. En el último cuarto del siglo XVIII, con la aparición de maestros con titulación expedida por el Consejo de Castilla, se abrió un duro pleito entre unos y otros que se saldó en favor de los titulados, aunque siguieron funcionando las escuelas de maestros sin titulación. Por último se estudia la situación de los preceptores de Latinidad y Gramática, que preparaban a los alumnos para ingresar en las universidades españolas, así como la situación que padeció la Universidad de Almagro en el siglo xviii, en evidente proceso de decadencia, como otras muchas universidades menores.It is a question of a work where the elementary and most top education is analyzed in the 18th century, in so singular city, since it it (he, she was Almagro in this century, where it managed to be the capital of the province of the la Mancha.

    1998-01-01

    This clear, concise introduction to the classical theory of one complex variable is based on the premise that "anything worth doing is worth doing with interesting examples." The content is driven by techniques and examples rather than definitions and theorems. This self-contained monograph is an excellent resource for a self-study guide and should appeal to a broad audience. The only prerequisite is a standard calculus course. The first chapter deals with a beautiful presentation of special functions. . . . The third chapter covers elliptic and modular functions. . . in much more detail, and from a different point of view, than one can find in standard introductory books. . . . For [the] subjects that are omitted, the author has suggested some excellent references for the reader who wants to go through these topics. The book is read easily and with great interest. It can be recommended to both students as a textbook and to mathematicians and physicists as a useful reference. ---Mathematical Reviews Mainly or...

  15. Extended symmetrical classical electrodynamics.

    2008-03-01

    In this paper, we discuss a modification of classical electrodynamics in which "ordinary" point charges are absent. The modified equations contain additional terms describing the induced charges and currents. The densities of the induced charges and currents depend on the vector k and the vectors of the electromagnetic field, E and B . It is shown that the vectors E and B can be defined in terms of two four-potentials and the components of k are the components of a four-tensor of the third rank. The Lagrangian of the modified electrodynamics is defined. The conditions are derived at which only one four-potential determines the behavior of the electromagnetic field. It is also shown that static modified electrodynamics can describe the electromagnetic field in the inner region of an electric monopole. In the outer region of the electric monopole the electric field is governed by the Maxwell equations. It follows from boundary conditions at the interface between the inner and outer regions of the monopole that the vector k has a discrete spectrum. The electric and magnetic fields, energy, and angular momentum of the monopole are found for different eigenvalues of k .

    Applying Feynman diagrammatics to non-fermionic strongly correlated models with local constraints might seem generically impossible for two separate reasons: (i) the necessity to have a Gaussian (non-interacting) limit on top of which the perturbative diagrammatic expansion is generated by Wick’s theorem, and (ii) Dyson’s collapse argument implying that the expansion in powers of coupling constant is divergent. We show that for arbitrary classical lattice models both problems can be solved/circumvented by reformulating the high-temperature expansion (more generally, any discrete representation of the model) in terms of Grassmann integrals. Discrete variables residing on either links, plaquettes, or sites of the lattice are associated with the Grassmann variables in such a way that the partition function (as well as all correlation functions) of the original system and its Grassmann-field counterpart are identical. The expansion of the latter around its Gaussian point generates Feynman diagrams. Our work paves the way for studying lattice gauge theories by treating bosonic and fermionic degrees of freedom on equal footing.

  17. Time, classical and quantum

    We propose a new point of view regarding the problem of time in quantum mechanics, based on the idea of replacing the usual time operator T with a suitable real-valued function T on the space of physical states. The proper characterization of the function T relies on a particular relation with the dynamical evolution of the system rather than with the infinitesimal generator of the dynamics (Hamiltonian). We first consider the case of classical hamiltonian mechanics, where observables are functions on phase space and the tools of differential geometry can be applied. The idea is then extended to the case of the unitary evolution of pure states of finite-level quantum systems by means of the geometric formulation of quantum mechanics. It is found that T is a function on the space of pure states which is not associated with any self-adjoint operator. The link between T and the dynamical evolution is interpreted as defining a simultaneity relation for the states of the system with respect to the dynamical evolution itself. It turns out that different dynamical evolutions lead to different notions of simultaneity, i.e., the notion of simultaneity is a dynamical notion.

  18. Classical competing risks

    2001-01-01

    If something can fail, it can often fail in one of several ways and sometimes in more than one way at a time. There is always some cause of failure, and almost always, more than one possible cause. In one sense, then, survival analysis is a lost cause. The methods of Competing Risks have often been neglected in the survival analysis literature. Written by a leading statistician, Classical Competing Risks thoroughly examines the probability framework and statistical analysis of data of Competing Risks. The author explores both the theory of the subject and the practicalities of fitting the models to data. In a coherent, self-contained, and sequential account, the treatment moves from the bare bones of the Competing Risks setup and the associated likelihood functions through survival analysis using hazard functions. It examines discrete failure times and the difficulties of identifiability, and concludes with an introduction to the counting-process approach and the associated martingale theory.With a dearth of ...

    Radio techniques were the nrst to lead astronomy away from the quiescent and limited Universe revealed by traditional observations at optical wave­ lengths. In the earliest days of radio astronomy, a handful of radio physicists and engineers made one startling discovery after another as they opened up the radio sky. With this collection of classic papers and the extensive intro­ ductory material, the reader can experience these exciting discoveries, as well as understand the developing techniques and follow the motivations which prompted the various lines of inquiry. For instance he or she will follow in detail the several attempts to detect radio waves from the sun at the turn of the century; the unravelling by Jansky of a "steady hiss type static"; the incredible story of Reber who built a 9 meter dish in his backyard in 1937 and then mapped the Milky Way; the vital discoveries by Hey and colleagues of radio bursts from the Sun and of a discrete source in the constellation of Cygnus; the development of re...

    The ITER plasma control system has the same functional scope as the control systems in present tokamaks. These are plasma operation scenario sequencing, plasma basic control (magnetic and kinetic), plasma advanced control (control of RWMs, NTMs, ELMs, error fields, etc) and plasma fast shutdown. This chapter considers only plasma initiation and plasma basic control. This chapter describes the progress achieved in these areas in the tokamak experiments since the ITER Physics Basis (1999 Nucl. Fusion 39 2577) was written and the results of assessment of ITER to provide the plasma initiation and basic control. This assessment was done for the present ITER design (15 MA machine) at a more detailed level than it was done for the ITER design 1998 (21 MA machine) described in the ITER Physics Basis (1999 Nucl. Fusion 39 2577). The experiments on plasma initiation performed in DIII-D and JT-60U, as well as the theoretical studies performed for ITER, have demonstrated that, within specified assumptions on the plasma confinement and the impurity influx, ITER can produce plasma initiation in a low toroidal electric field (0.3 V m-1), if it is assisted by about 2 MW of ECRF heating. The plasma basic control includes control of the plasma current, position and shape—the plasma magnetic control, as well as control of other plasma global parameters or their profiles—the plasma performance control. The magnetic control is based on more reliable and simpler models of the control objects than those available at present for the plasma kinetic control. Moreover the real time diagnostics used for the magnetic control in many cases are more precise than those used for the kinetic control. Because of these reasons, the plasma magnetic control was developed for modern tokamaks and assessed for ITER better than the kinetic control. However, significant progress has been achieved in the plasma performance control during the last few years. Although the physics basis of plasma operation

    Covers the whole breadth of mineral dust research, from a scientific perspective Presents interdisciplinary work including results from field campaigns, satellite observations, laboratory studies, computer modelling and theoretical studies Explores the role of dust as a player and recorder of environmental change This volume presents state-of-the-art research about mineral dust, including results from field campaigns, satellite observations, laboratory studies, computer modelling and theoretical studies. Dust research is a new, dynamic and fast-growing area of science and due to its multiple roles in the Earth system, dust has become a fascinating topic for many scientific disciplines. Aspects of dust research covered in this book reach from timescales of minutes (as with dust devils, cloud processes, and radiation) to millennia (as with loess formation and oceanic sediments), making dust both a player and recorder of environmental change. The book is structured in four main parts that explore characteristics of dust, the global dust cycle, impacts of dust on the Earth system, and dust as a climate indicator. The chapters in these parts provide a comprehensive, detailed overview of this highly interdisciplinary subject. The contributions presented here cover dust from source to sink and describe all the processes dust particles undergo while travelling through the atmosphere. Chapters explore how dust is lifted and transported, how it affects radiation, clouds, regional circulations, precipitation and chemical processes in the atmosphere, and how it deteriorates air quality. The book explores how dust is removed from the atmosphere by gravitational settling, turbulence or precipitation, how iron contained in dust fertilizes terrestrial and marine ecosystems, and about the role that dust plays in human health. We learn how dust is observed, simulated using computer models and forecast. The book also details the role of dust deposits for climate reconstructions

    2015-01-01

    Full Text Available The subject of our study is the policy of the Avar Khans towards Russia in XVIII XIX centuries. Most researchers believe that the Avar Khans State was always interested in close relations with the powerful nation, pursued a policy of deepening relations and, almost always, been loyal to Russia. This can be seen in the period of open confrontation Highlanders during the Caucasian War. Of course, such a policy could not lead to conflicts between the Avar Khan State and its nearest neighbors, causing the latter to exercise intolerance such loyalty to Russia. All of these issues are covered with the involvement of the literary and archival materials. Thus, based on the analysis of sources, the author establishes that the manifestation of the desire of the Avar Khan State, which occupies an isolated position in relation to other feudal lords, the establishment of a strong alliance with Russia is always determined by the desire Khans have Russia as a strong and reliable ally than to amass it in as an enemy. On the basis of archival sources, we can state the fact that Russia, in turn, highly valued the loyalty of Khan's house and noted it all sorts of honors.

    Full Text Available The article discusses the history of christianity in the Caucasus in the IV–XVIII centuries. The main attention is paid to the complex process of the formation and fate of christianity among the various peoples of the region, the role of Byzantine, Georgian and Russian christian missionaries. Among the sources there are used the pre-revolutionary materials on the history of christianity in the Caucasus, as well as scientific publications. The decision of research tasks is based on the principle of historicism. The problem of the spread of christianity in the Caucasus, while maintaining the pagan beliefs are seen as a consequence of specific socio-historical conditions, in the formation of which the important role was played by external factors, and also the conservative mentality of highlanders. In conclusion, the authors note that every of the caucasian peoples had its story of the spread and adoption of christianity in the Caucasus. On the one hand, the ancient christian Armenia and Georgia, relatively quickly emerging with paganism, on the other, the mountain tribes, who had no public began taking christianity in the reduced forms under the influence of Byzantium, Georgia, Russia with the broad preservation of pagan beliefs. Ultimately, under the influence of the first Crimean khans, and then the Ottoman Empire, these tribes have consistently converted to Islam.

    Full Text Available Since the Renaissance, the Tiber River has been the object of the most unusual archaeological quests, driven mainly by fantastic medieval lore. In the 18th and 19th centuries, the excavations on the river intensified and were epitomized by the scientific atmosphere of the Enlightenment, even tough they resulted in little archaeological worth. In 1819, even the Spanish monarch Fernando VII almost became a Shareholder in one of these archaeological companies. After the Italian unification, many finds were discovered in the works done along the Tiber's urban region, of wich many are now in the Museo Nazionale Romano.Desde el Renacimiento el Tiber ha sido objeto de las más peregrinas búsquedas arqueológicas, emprendidas habitualmente sobre la base de fantásticos relatos medievales. En los siglos XVIII y XIX las excavaciones en el río se intensificaron y se dotaron del cientificismo propio de la Ilustración, siendo no obstante el fruto de estos trabajos muy escaso; en 1819, incluso el propio monarca español Fernando VII estuvo a punto de convertirse en accionista de una de estas empresas arqueológicas. Tras la Unificación italiana, las obras de estructuración del curso urbano del Tiber propiciaron finalmente numerosos hallazgos, muchos de los cuales se conservan en el Museo Nazionale Romano.

"La Science des Ingénieurs...", signed by Bernard Forest de Belidor, a french man of catalan origin, mathematics teacher in La Fére Artillery School, member as well of the Scientific Societies of London and Prussia and a correspondent of the Paris Royal Academy of Sciences. In this book we will appreciate a firm direction change in two fundamental aspects of the technical culture of actual engineers: the way to dimension structures, starting from the numerical procedures and the organization of the processes in construction works In the following pages I want to introduce you into the contents of this treatise in its original version and in its castiílan particular translation. But, before this, I have also to explain the teatrise role in the disociation of two professions that, till this time. have share attitudes and competitivines: architecture and engineering, such as they were understood in the Renaissance distant years where the durability, stability and solidity of a building, watever it was, was preceded by a perfect execution, by the use of appropriated materials, and where the different parts were measured following a general plan of whole proportions and the search of balance elements. We will see how -based on the science of these XVIII century engineers- all those principies have to be explained through the nature of the algebraical reasons, the mechanical knowledge and the abstract understanding of the structural elements. It is worthwhile to point out that this work is a part of a much more important investigation concerning the transformations of the technical knowledge concerning engineering and architecture between XVI and XVIII centuries, as well in Europe as in America, insisting on the role played by the academies and schools, in one or the other ocean side.En 1729 aparece publicado en París el

    Full Text Available El discurso de la limpieza de sangre es esencial para la comprensión de los valores de las sociedades hispanas de la época colonial. En este artículo se muestra cómo un discurso originado en el continente europeo pasó a ser la base del sistema de estratificación social en el nuevo orden colonial y se analiza el impacto de la transferencia de ideas desde España a las sociedades coloniales, a partir del estudio del Colegio de Abogados de Caracas. El concepto de limpieza de sangre en la provincia de Caracas fue distinto del establecido en la metrópolis. En estas tierras, la limpieza de sangre fue preocupación de todos los grupos sociales que conformaban la provincia durante el siglo XVIII y elemento fundamental para que la élite criolla mantuviera el control de las instituciones civiles y eclesiásticas.

Buscaban el exterminio del predador para acabar con los desmanes en los rebaños de ganado y con el temor ancestral, revivido constantemente en cuentos y leyendas.

    This chapter summarized the scope of what is known and not known about climate in the Southwestern United States. There is now more evidence and more agreement among climate scientists about the physical climate and related impacts in the Southwest compared with that represented in the 2009 National Climate Assessment (Karl, Melillo, and Peterson 2009). However, there remain uncertainties about the climate system, the complexities within climate models, the related impacts to the biophysical environment, and the use of climate information on decision making. Uncertainty is introduced in each step of the climate planning-an-response process--in the scenarios used to drive the climate models, the information used to construct the models, and the interpretation and use of the model' data for planning and decision making (Figure 19.1). There are server key challenge, drawn from recommendations of the authors of this report, that contribute to these uncertainties in the Southwest: - There is a dearth of climate observations at high elevations and on the lands of Native nations.

  18. Chapter 14: Web-based Tools - WESIX

    Science.gov (United States)

    Krughoff, K. S.; Connolly, A. J.

    We present here the design and features of the Web Enabled Source Identifier with X-Matching (WESIX). With the proliferation of large imaging surveys, it has become increasingly apparent that tasks performed frequently by astronomers need to be made available in a web-aware manner. The reasons for this are twofold: First, it is no longer feasible to work with the complete data sets. Calculations are much more efficient if they can be carried out at the data center where large files can be transferred quickly. Second, exploratory science can be greatly facilitated by combining common tasks into integrated web services. WESIX addresses both of these issues. It is deployable to large data centers where source identification can be carried out at the data source. In addition, WESIX can transparently leverage the capabilities of Open SkyQuery to crossmatch with large catalogs. The result is a web-based service that integrates object detection with the ability to crossmatch against published catalog data. In this chapter we will discuss how WESIX is constructed, its functionality and some example usage. Section 1 will give a brief overview of the architecture of the service. Section 2 will introduce the features of the service through both the web browser and SOAP web service interfaces. Section 3 gives a detailed overview of the web service methods. Section 4 walks through the example client distributed with the software package.

  19. Innovation: the classic traps.

    Kanter, Rosabeth Moss

    2006-11-01

    Never a fad, but always in or out of fashion, innovation gets rediscovered as a growth enabler every half dozen years. Too often, though, grand declarations about innovation are followed by mediocre execution that produces anemic results, and innovation groups are quietly disbanded in cost-cutting drives. Each managerial generation embarks on the same enthusiastic quest for the next new thing. And each generation faces the same vexing challenges- most of which stem from the tensions between protecting existing revenue streams critical to current success and supporting new concepts that may be crucial to future success. In this article, Harvard Business School professor Rosabeth Moss Kanter reflects on the four major waves of innovation enthusiasm she's observed over the past 25 years. She describes the classic mistakes companies make in innovation strategy, process, structure, and skills assessment, illustrating her points with a plethora of real-world examples--including AT&T Worldnet, Timberland, and Ocean Spray. A typical strategic blunder is when managers set their hurdles too high or limit the scope of their innovation efforts. Quaker Oats, for instance, was so busy in the 1990s making minor tweaks to its product formulas that it missed larger opportunities in distribution. A common process mistake is when managers strangle innovation efforts with the same rigid planning, budgeting, and reviewing approaches they use in their existing businesses--thereby discouraging people from adapting as circumstances warrant. Companies must be careful how they structure fledgling entities alongside existing ones, Kanter says, to avoid a clash of cultures and agendas--which Arrow Electronics experienced in its attempts to create an online venture. Finally, companies commonly undervalue and underinvest in the human side of innovation--for instance, promoting individuals out of innovation teams long before their efforts can pay off. Kanter offers practical advice for avoiding

  20. CLASSICISM STYLE IN GUNS‟ DECORATIONS (ON THE EXAMPLE OF I. LYALYIN

    Directory of Open Access Journals (Sweden)

    A. V. BAHMETOVA

    2015-01-01

    Full Text Available The article examines and analyses the works of the most famous gunsmith of the XVIII – early XIX centuries, Ivan Lyalyin, who was one of the founders of the new style tendencies in decorating small arms of Tula meeting the spirit of those times and the aesthetics of classicism style. All samples of decorated arms were created by imagination and professional skills of gunsmiths not by chance. They reflected the development of the technologies and the history of styles which followed each other. The arms of the late XVIII century show the great interest to the antiquity, what is reflected in the décor elements borrowed from the Roman Empire heritage, including accessories and fittings reminding the ancient Roman ones (lictor‟s fasces, javelins, arrows in quivers, garlands made of leaves and roses, vases, wreaths, Amour‟s heads, heraldic images of animals and so on. Ivan Lyalyin is also famous for his original colour décor solutions. He used combinations of white bone and golden-plated bronze, sometimes adding black patterns or gilded bone and expensive types of wood to make his works look festive and posh. Lyalyin used new materials and technologies, created original technical solutions in designing arms. His followers and like-minded gunsmiths kept on developing his creative principles and styles, what brought to the creation of «the School of Ivan Lyalyin».

    The application of a classical approach to various quantum problems - the secular perturbation approach to quantization of a hydrogen atom in external fields and a helium atom, the adiabatic switching method for calculation of a semiclassical spectrum of hydrogen atom in crossed electric and magnetic fields, a spontaneous decay of excited states of a hydrogen atom, Gutzwiller's approach to Stark problem, long-lived excited states of a helium atom recently discovered with the help of Poincar$\\acute{\\mathrm{e}}$ section, inelastic transitions in slow and fast electron-atom and ion-atom collisions - is reviewed. Further, a classical representation in quantum theory is discussed. In this representation the quantum states are treating as an ensemble of classical states. This approach opens the way to an accurate description of the initial and final states in classical trajectory Monte Carlo (CTMC) method and a purely classical explanation of tunneling phenomenon.

  10. Classical dynamics a modern perspective

    CERN Document Server

    Sudarshan, Ennackal Chandy George

    2016-01-01

    Classical dynamics is traditionally treated as an early stage in the development of physics, a stage that has long been superseded by more ambitious theories. Here, in this book, classical dynamics is treated as a subject on its own as well as a research frontier. Incorporating insights gained over the past several decades, the essential principles of classical dynamics are presented, while demonstrating that a number of key results originally considered only in the context of quantum theory and particle physics, have their foundations in classical dynamics.Graduate students in physics and practicing physicists will welcome the present approach to classical dynamics that encompasses systems of particles, free and interacting fields, and coupled systems. Lie groups and Lie algebras are incorporated at a basic level and are used in describing space-time symmetry groups. There is an extensive discussion on constrained systems, Dirac brackets and their geometrical interpretation. The Lie-algebraic description of ...

  11. Molecular Analysis of Collagen XVIII Reveals Novel Mutations, Presence of a Third Isoform, and Possible Genetic Heterogeneity in Knobloch Syndrome

    2002-01-01

    Knobloch syndrome (KS) is a rare disease characterized by severe ocular alterations, including vitreoretinal degeneration associated with retinal detachment and occipital scalp defect. The responsible gene, COL18A1, has been mapped to 21q22.3, and, on the basis of the analysis of one family, we have demonstrated that a mutation affecting only one of the three COL18A1 isoforms causes this phenotype. We report here the results of the screening of both the entire coding region and the exon-intron boundaries of the COL18A1 gene (which includes 43 exons), in eight unrelated patients with KS. Besides 20 polymorphic changes, we identified 6 different pathogenic changes in both alleles of five unrelated patients with KS (three compound heterozygotes and two homozygotes). All are truncating mutations leading to deficiency of one or all collagen XVIII isoforms and endostatin. We have verified that, in exon 41, the deletion c3514-3515delCT, found in three unrelated alleles, is embedded in different haplotypes, suggesting that this mutation has occurred more than once. In addition, our results provide evidence of nonallelic genetic heterogeneity in KS. We also show that the longest human isoform (NC11-728) is expressed in several tissues (including the human eye) and that lack of either the short variant or all of the collagen XVIII isoforms causes similar phenotypes but that those patients who lack all forms present more-severe ocular alterations. Despite the small sample size, we found low endostatin plasma levels in those patients with mutations leading to deficiency of all isoforms; in addition, it seems that absence of all collagen XVIII isoforms causes predisposition to epilepsy.

  18. Simultaneous classical-quantum capacities of quantum multiple access channels

    CERN Document Server

    Yard, J

    2005-01-01

    The rates at which classical and quantum information can be simultaneously transmitted from two spatially separated senders to a single receiver over an arbitrary quantum channel are characterized. Two main results are proved in detail. The first describes the region of rates at which one sender can send classical information while the other sends quantum information. The second describes those rates at which both senders can send quantum information. For each of these situations, an example of a channel is given for which the associated region admits a single-letter description. This is the author's Ph.D. dissertation, submitted to the Department of Electrical Engineering at Stanford University in March, 2005. It represents an expanded version of the paper quant-ph/0501045, containing a number of tutorial chapters which may be of independent interest for those learning about quantum Shannon theory.

This type of institution propagates immediately by all Italian geography, and going beyond its borders will arrive at other European zones, among them to the Iberian Peninsula. Within the Hispanic monarchy in the beginnings of century XVIII the foundation of Monte de Piedad of Madrid takes place, by Piquer Father who will be inheriting of the spirit and objectives of primitive Italian predecessors and will include some new features as a result of the devotion of their founder and the particularities of that time. This Monte will serve as a model for other similar institutions as much in the peninsula as in the American virreinatos. With time, a series of new foundations will take place, bearing the same denomination (all will take by name Monte de Piedad, but with important differences in their constitutions and aims.

    Full Text Available The article discloses a feature of graphic ornamental motives of embroidery in clothing and household decoration, typical for the North-West region of Russia in the XVIII century. The semiotic status of the Russian clothing and household decorations with decorative ornaments embroidery with figurative ornamental motives as a group of functionally related items have remained very high, having both utilitarian and sign pragmatics for millennia. Despite the sociohistorical processes, changing the external shape of the suit, the symbolism of embroidery patterns remained unchanged and continued to exist until the twentieth century. In connection with the political events, readier subjects and fine motives can be traced in the Russian folk embroidery due to the resettlement of Novgorod in the XV century. This is the way from Novgorod to Arkhangelsk and the path from Veliky Novgorod to Vologda where Novgorod settled, keeping their culture. It is proved, that there is a correlation between the zoomorphic pendants, amulets female ornaments of the tenth century and plot embroidered with iconic ornamental motives of the North-West region of Russia. People piously observed the laws of their fathers and grandfathers. The embroidery from generation to generation has been portraying images of ancient mythology. The most common images in the northern Russian embroidery were the goddess of Mokos, Rozhanitsy, birds, horses, moose, deer, and wild animals and plants, depicted in subject compositions. The zoomorphic motives are also the images of flying dragons, symbolizing lightning, they are often found in Russian folk tales. Fire Dragon was considered the protector of property and fire. The people’s attitude to fire was special: it was called "You sir, the King-fire", and it was regards’ a god. One of the main roles in the embroidery is given to the technical side. Counted Russian embroidery stitches do not only recreate the image, but also express its

    Full Text Available El presente artículo examina las instalaciones y el equipamiento de los establecimientos vitivinícolas del Reino de Chile en el siglo XVIII. El tema es relevante porque en ese momento, Chile era el principal polo vitivinícola de América y ejercía un liderazgo en la región. Se estudian las distintas formas de lagares, tanto los de cuero como los de adobe, cal y ladrillo; también se indaga en la evolución de la vasija vinaria, de la greda la madera. Los hornos botijeros ocuparon un lugar importante por su aporte a la fabricación de tinajas y botijas. Estos recipientes fueron como un icono característico de la viticultura del sur de América (en México la vasija no era de greda sino de madera, aún al comienzo de la industria vitivinícola. Posteriormente, a partir de la mitad de la centuria, comenzó la incorporación de vasija de madera (pipas y barriles en Chile. Durante cincuenta años éstas convivieron con los recipientes de greda, hasta comenzar a sustituirlos progresivamente en el siglo XIX. Este equipamiento hizo posible el desarrollo de una de las principales industrias que hubo en América española durante la época colonial y que, actualmente, sigue siendo la principal industria de Chile.

    Full Text Available The present article describes a chemical and physical study of the colour, chemical composition and mineral phases of the decorative materials in the Seville City Hall Chapter House ceiling. The findings showed that the inner most layer of material, calcite, was covered with white lead, in turn concealed under a layer of gilded bole. The ceiling underwent re-gilding, also over bole, due in all likelihood to wear on the original gold leaf. In the nineteenth century, the entire ceiling with the exception of the inscriptions was whitewashed with calcite and white lead. Silver was employed on King John I’s sword (coffer 27. Gold leaf was used to adorn the royal attributes: crowns, belts, sceptres, swords and rosary beads. The high reliefs were likewise gilded. The pigments identified on the ceiling adornments included azurite, malachite, vermilion and gas black. A lime and ground dolomite mortar was used throughout.

    El objetivo de este trabajo es el estudio de diferentes aspectos, como el color, la composición química y las fases mineralógicas presentes en los diferentes materiales que forman la ornamentación del techo de la Sala Capitular del Ayuntamiento de Sevilla, mediante métodos físicos y químicos. Nuestros resultados muestran que el dorado fue realizado sobre una capa de bol previamente depositada sobre una lámina de blanco de plomo que cubría un estrato de calcita. Posteriormente, y probablemente debido a alteraciones en el dorado original, el techo fue de nuevo dorado usando una técnica similar. En el siglo XIX, casi todo el techo, excepto las zonas con inscripciones, fue blanqueado usando una mezcla de calcita y blanco de plomo. Se empleó plata para cubrir la espada del rey Juan I (casetón 27. Finísimas láminas de oro se usaron para decorar los atributos reales: coronas, cinturones, cetros, espadas y rosarios.

  19. Classical Knowledge for Quantum Security

    CERN Document Server

    D'Hondt, Ellie

    2008-01-01

    We propose a decision procedure for analysing security of quantum cryptographic protocols, combining a classical algebraic rewrite system for knowledge with an operational semantics for quantum distributed computing. As a test case, we use our procedure to reason about security properties of a recently developed quantum secret sharing protocol that uses graph states. We analyze three different scenarios based on the safety assumptions of the classical and quantum channels and discover the path of an attack in the presence of an adversary. The epistemic analysis that leads to this and similar types of attacks is purely based on our classical notion of knowledge.

    Quantum localization of classical mechanics within the BRST-BFV and BV (or field-antifield) quantization methods are studied. It is shown that a special choice of gauge fixing functions (or BRST-BFV charge) together with the unitary limit leads to Hamiltonian localization in the path integral of the BRST-BFV formalism. In turn, we find that a special choice of gauge fixing functions being proportional to extremals of an initial non-degenerate classical action together with a very special solution of the classical master equation result in Lagrangian localization in the partition function of the BV formalism.

  2. The Wigner representation of classical mechanics, quantization and classical limit

    2001-08-01

    Starting from the Liouvillian formulation of classical physics it is possible by means of a Fourier transform to introduce the Wigner representation and to derive an operator structure to classical mechanisms. The importance of this new representation lies on the fact that it turns out to be suitable route to establish a general method of quantization directly from the equations of motion without alluding to the existence of Hamiltonian and Lagrangian functions. Following this approach we quantize only the motion of a Browian particle with non-linear friction in the Markovian approximation - the thermal bath may be quantum or classical -, thus when the bath is classically described we obtain a master equation which reduces to Caldeira-Legget equation for the linear friction case, and when the reservoir is quantum we get an equation reducing to the one found by Caldeira et al. By neglecting the environmental influence we show that the system can be approximately described by equations of motion in terms of wave function, such as the Schrodinger-Langevin equation and equations of the Caldirola-Kanai type. Finally to make the present study self-consistent we evaluate the classical limit of these dynamical equations employing a new classical limiting method h/2{pi} {yields} 0. (author)

    We present the simplest model for classical transitions in flux vacua. A complex field with a spontaneously broken U(1) symmetry is embedded in $M_2\\times S_1$. We numerically construct different winding number vacua, the vortices interpolating between them, and simulate the collisions of these vortices. We show that classical transitions are generic at large boosts, independent of whether or not vortices miss each other in the compact $S_1$.

    1990-01-01

    The divergent part of the self force of a radiating string coupled to gravity, an antisymmetric tensor and a dilaton in four dimensions are calculated to first order in classical perturbation theory. While this divergence can be absorbed into a renormalization of the string tension, demanding that both it and the divergence in the energy momentum tensor vanish forces the string to have the couplings of compactified N = 1 D = 10 supergravity. In effect, supersymmetry cures the classical infinities.

No obstante, en México se hicieron varias publicacionesde cierto relieve, en especial por los misioneros jesuitas y otros estudiosos de la Nueva España. Esinteresante mencionar que aun con la trascendencia de Linneo para la biología moderna, algunoshistoriadores de los anfibios y los reptiles señalan que por lo menos para la herpetofauna de Méxicoexistió una importante regresión, ya que era mucho mayor el conocimiento que había dejadoFrancisco Hernández en el siglo XVI. Las contribuciones de los autores de la escuela francesa comoBuffon y quienes lo sucedieron como Lacepéde y Daudin, fueron los grandes pilares de laherpetología o estudios de los anfibios y los reptiles de la manera en que la conocemos en laactualidad. Las bases establecidas en el siglo XVIII sirvieron para que con la apertura de México almundo a partir de su independencia, se entrara en una de las etapas de mayor relevancia para laherpetología del país.

    Kazan Federal University has held the annual International Youth School "Coherent Optics and Optical Spectroscopy" since 1997. The choice of the topic is not accidental. Kazan is the home of photon echo which was predicted at Kazan Physical-Technical Institute in 1963 by Prof. U.G. Kopvil'em and V.R. Nagibarov and observed in Columbia University by N.A. Kurnit, I.D. Abella, and S.R. Hartmann in 1964. Since then, photon echo has become a powerful tool of coherent optical spectroscopy and optical information processing, which have been developed here in Kazan in close collaboration between Kazan Physical-Technical Institute and Kazan Federal University. The main subjects of the XVIII International Youth School are: Nonlinear and coherent optics; Atomic and molecular spectroscopy; Coherent laser spectroscopy; Problems of quantum optics; Quantum theory of radiation; and Nanophotonics and Scanning Probe Microscopy. The unchallenged organizers of that school are Kazan Federal University and Kazan E.K. Zavoisky Physical-Technical Institute. The rector of the School is Professor Myakzyum Salakhov, and the vice-rector is Professor Vitaly Samartsev. The International Youth Scientific School "Coherent Optics and Optical Spectroscopy" follows the global pattern of comprehensive studies of matter properties and their interaction with electromagnetic fields. Since 1997 more than 100 famous scientists from the USA, Germany, Ukraine, Belarus and Russia have given plenary lecture presentations. Here over 1000 young scientists had an opportunity to participate in lively discussions about the latest scientific news. Many young people have submitted interesting reports on photonics, quantum electronics, laser physics, quantum optics, traditional optical and laser spectroscopy, non-linear optics, material science and nanotechnology. Here we are publishing the fullsize papers prepared from the most interesting lectures and reports selected by the Program Committee of the School. The

    Full Text Available RESUMEN: Se ponen de relieve dos aspectos fundamentales y concatenados durante el siglo XVIII: el arraigo de numerosas prácticas religiosas colectivas en el seno familiar y la relación entre las vivencias domésticas y las formas externas de la existencia cotidiana popular.Se analizan la reiteración de los rituales funerarios sacralizados y el consumo de ropa, y la incidencia de ambos temas en las prácticas culturales populares. El mantenimiento de los signos externos de la religiosidad y los cambios en la civilización material tenían igual cabida en la cotidianidad de aquella Castilla semiilustrada.La gran cuestión giraba en torno a la necesaria mezcla de los cuidados espirituales y mundanos para lograr una cómoda felicidad terrena junto a la ansiada salvación. «Nada de lo divino era extraño; todo era religión»; pero también era una realidad en la época el ideal: «viva la industria de la persona».ABSTRACT: This paper highlights two fundamental closely connected developments of the Eighteenth century in Castile, namely: that many collective religious practices became deeply rooted in the family household; also, that a relationship took shape between domestic experiences and the outer forms of the people’s daily existence.Thus the reiteration of sacralized burial rites and the consumption of clothing are analysed, as well as the effect of both on popular culture practices. In the everyday life of semi-Enlightened Castile, the preservation of external signs of religiousness was on an equal footing with the evolution of material culture. It was a matter of attaining the necessary mixing of spiritual and worldly cares so as to attain comfortable, earthly happiness along with the much longed-for salvation. «Nada de lo divino era extraño; todo era religión», but no less true was the motto: «viva la industria de la persona».

  1. Censura gubernativa, Iglesia e inquisición en el siglo XVIII

    Directory of Open Access Journals (Sweden)

    Caro López, Ceferino

    2004-12-01

    Full Text Available Government censorship in Eighteenth Century Spain was another means of the Spanish Enlightenment policy. Until mid-century both powers of Church and State were balanced; from Charles Ill's reign on the censorship of the Consejo de Castilla tried to control and restrict not only the traditional power of the Inquisition, but also the intellectual output of the country, either ideological —criticism on the Crown's policy— or cultural-publishing religious works. It is important to notice that many members of the clergy collaborated with the State in that task; and also that, after the French Revolution, the Inquisition regained its previous role. In the last decade of the Seventeenth century the irreconcilable clash between the advocates and the critics of the Inquisition became evident.

    La práctica de la censura gubernativa fue, en el siglo XVIII, un instrumento más de la política regalista de la Ilustración española. Si hasta mediados del siglo se mantuvieron estables las relaciones de poder entre Iglesia y Estado, a partir del reinado de Carlos III se nota cómo la censura del Consejo de Castilla intentaba vigilar y limitar no sólo el tradicional poder de la Inquisición, sino también la producción ideológica —crítica a la política de la Corona— y cultural-edición de obras de religión. Es importante observar que muchos hombres de Iglesia colaboraron con el Estado en esas tareas; y también que tras la Revolución Francesa la Inquisición volvió a asumir el papel que había jugado con anterioridad. En el último decenio del Setecientos se pone de manifiesto el enfrentamiento irreconciliable entre los partidarios y los detractores de la Inquisición.

  2. Hermeneutic reading of classic texts.

    2013-09-01

    The purpose of this article is to broaden the understandinfg of the hermeneutic reading of classic texts. The aim is to show how the choice of a specific scientific tradition in conjunction with a methodological approach creates the foundation that clarifies the actual realization of the reading. This hermeneutic reading of classic texts is inspired by Gadamer's notion that it is the researcher's own research tradition and a clearly formulated theoretical fundamental order that shape the researcher's attitude towards texts and create the starting point that guides all reading, uncovering and interpretation. The researcher's ethical position originates in a will to openness towards what is different in the text and which constantly sets the researcher's preunderstanding and research tradition in movement. It is the researcher's attitude towards the text that allows the text to address, touch and arouse wonder. Through a flexible, lingering and repeated reading of classic texts, what is different emerges with a timeless value. The reading of classic texts is an act that may rediscover and create understanding for essential dimensions and of human beings' reality on a deeper level. The hermeneutic reading of classic texts thus brings to light constantly new possibilities of uncovering for a new envisioning and interpretation for a new understanding of the essential concepts and phenomena within caring science.

  3. Does classical liberalism imply democracy?

    Directory of Open Access Journals (Sweden)

    David Ellerman

    2015-12-01

    Full Text Available There is a fault line running through classical liberalism as to whether or not democratic self-governance is a necessary part of a liberal social order. The democratic and non-democratic strains of classical liberalism are both present today—particularly in the United States. Many contemporary libertarians and neo-Austrian economists represent the non-democratic strain in their promotion of non-democratic sovereign city-states (start-up cities or charter cities. We will take the late James M. Buchanan as a representative of the democratic strain of classical liberalism. Since the fundamental norm of classical liberalism is consent, we must start with the intellectual history of the voluntary slavery contract, the coverture marriage contract, and the voluntary non-democratic constitution (or pactum subjectionis. Next we recover the theory of inalienable rights that descends from the Reformation doctrine of the inalienability of conscience through the Enlightenment (e.g. Spinoza and Hutcheson in the abolitionist and democratic movements. Consent-based governments divide into those based on the subjects’ alienation of power to a sovereign and those based on the citizens’ delegation of power to representatives. Inalienable rights theory rules out that alienation in favor of delegation, so the citizens remain the ultimate principals and the form of government is democratic. Thus the argument concludes in agreement with Buchanan that the classical liberal endorsement of sovereign individuals acting in the marketplace generalizes to the joint action of individuals as the principals in their own organizations.

    At a fundamental level, the classical picture of the world is dead, and has been dead now for almost a century. Pinning down exactly which quantum phenomena are responsible for this has proved to be a tricky and controversial question, but a lot of progress has been made in the past few decades. We now have a range of precise statements showing that whatever the ultimate laws of Nature are, they cannot be classical. In this article, we review results on the fundamental phenomena of quantum theory that cannot be understood in classical terms. We proceed by first granting quite a broad notion of classicality, describe a range of quantum phenomena (such as randomness, discreteness, the indistinguishability of states, measurement-uncertainty, measurement-disturbance, complementarity, noncommutativity, interference, the no-cloning theorem, and the collapse of the wave-packet) that do fall under its liberal scope, and then finally describe some aspects of quantum physics that can never admit a classical understandi...

Further, a classical representation in quantum theory is discussed. In this representation the quantum states are treated as an ensemble of classical states. This approach opens the way to an accurate description of the initial and final states in classical trajectory Monte Carlo (CTMC) method and a purely classical explanation of tunneling phenomenon. The general aspects of the structure of the semiclassical series such as renormgroup symmetry, criterion of accuracy and so on are reviewed as well.

    Full Text Available Growth subject in economics is an important factor of development. Classic economics ecole indicates the population as main variable which tender of growth. On the other hand T. R. Malthus is known as economist who regards population as a problem and brings up it among the classical economists. However, Adam Smith is an intellectual who discussed population problem earlier on the classic economics theory. According to Adam Smith one of the main factors that realise the growth is labour. In addition to population made it established. The aim of this study is analyzing the mental relationship between Malthus whose name has been identified with relation between population-growth and Smith who discussed this subject first time but put it off on process of theorisation.

  10. Classical planning and causal implicatures

    DEFF Research Database (Denmark)

    Blackburn, Patrick Rowan; Benotti, Luciana

    In this paper we motivate and describe a dialogue manager (called Frolog) which uses classical planning to infer causal implicatures. A causal implicature is a type of Gricean relation implicature, a highly context dependent form of inference. As we shall see, causal implicatures are important...... to generate clarification requests"; as a result we can model task-oriented dialogue as an interactive process locally structured by negotiation of the underlying task. We give several examples of Frolog-human dialog, discuss the limitations imposed by the classical planning paradigm, and indicate...

  11. Comparing classical and quantum equilibration

    CERN Document Server

    Malabarba, Artur S L; Short, Anthony J

    2016-01-01

    By using a physically-relevant and theory independent definition of measurement-based equilibration, we show quantitatively that equilibration is easier for quantum systems than for classical systems, in the situation where the initial state of the system is completely known (pure state). This shows that quantum equilibration is a fundamental, nigh unavoidable, aspect of physical systems, while classical equilibration relies on experimental ignorance. When the state is not completely known, a mixed state, this framework also shows quantum equilibration requires weaker conditions.

  12. Principal bundles the classical case

    CERN Document Server

    Sontz, Stephen Bruce

    2015-01-01

    This introductory graduate level text provides a relatively quick path to a special topic in classical differential geometry: principal bundles.  While the topic of principal bundles in differential geometry has become classic, even standard, material in the modern graduate mathematics curriculum, the unique approach taken in this text presents the material in a way that is intuitive for both students of mathematics and of physics. The goal of this book is to present important, modern geometric ideas in a form readily accessible to students and researchers in both the physics and mathematics communities, providing each with an understanding and appreciation of the language and ideas of the other.

  13. Quantum teleportation without classical channel

    2016-11-01

    For the first time, we show how quantum teleportation can be achieved without the assistance of classical channels. Our protocol does not need any pre-established entangled photon pairs beforehand. Just by utilizing quantum Zeno effect and couterfactual communication idea, we can achieve two goals; entangling a photon and an atom and also disentangling them by non-local interaction. Information is completely transferred from atom to photon with controllable disentanglement processes. More importantly, there is no need to confirm teleportation results via classical channels.

    We analyze the procedure of lifting in classical stochastic and quantum systems. It enables one to `lift' a state of a system into a state of `system+reservoir'. This procedure is important both in quantum information theory and the theory of open systems. We illustrate the general theory of liftings by a particular class related to so called circulant states.

  7. Numerical approaches to complex quantum, semiclassical and classical systems

    Energy Technology Data Exchange (ETDEWEB)

    Schubert, Gerald

    2008-11-03

    In this work we analyse the capabilities of several numerical techniques for the description of different physical systems. Thereby, the considered systems range from quantum over semiclassical to classical and from few- to many-particle systems. In chapter 1 we investigate the behaviour of a single quantum particle in the presence of an external disordered background (static potentials). Starting from the quantum percolation problem, we address the fundamental question of a disorder induced (Anderson-) transition from extended to localised single-particle eigenstates. Distinguishing isolating from conducting states by applying a local distribution approach for the local density of states (LDOS), we detect the quantum percolation threshold in two- and three-dimensions. Extending the quantum percolation model to a quantum random resistor model, we comment on the possible relevance of our results to the influence of disorder on the conductivity in graphene sheets. For the calculation of the LDOS as well as for the Chebyshev expansion of the time evolution operator, the kernel polynomial method (KPM) is the key numerical technique. In chapter 2 we examine how a single quantum particle is influenced by retarded bosonic fields that are inherent to the system. Within the Holstein model, these bosonic degrees of freedom (phonons) give rise to an infinite dimensional Hilbert space, posing a true many-particle problem. Constituting a minimal model for polaron formation, the Holstein model allows us to study the optical absorption and activated transport in polaronic systems. Using a two-dimensional variant of the KPM, we calculate for the first time quasi-exactly the optical absorption and dc-conductivity as a function of temperature. In chapter 3 we come back to the time evolution of a quantum particle in an external, static potential and investigate the capability of semiclassical approximations to it. We address basic quantum effects as tunneling, interference and

Her text constituted by sixty five letters, addressed to her father confessor, the jesuit Manuel Alvarez. These letters are kept in the Archive of the Dominican Monastery of Santa Rosa de Lima in Santiago, Chile. The letters seem a manifestation of confessional discourse which the nuns had to write by order of their father confessors or ecclesiastical autorities. However, the Epistolary analysis reveals the transformations of that discoursive pattern, which Sor Josefa's writing constitutes itself in the support of a selfknowing process and in a construction of woman identity, which is not recognized only in her religious vocation and virtues, but also in her knowing capacity, wisdom and words management.

    2001-04-01

    . We describe the pattern of dental development of Hominid XVIII from the Middle Pleistocene Sima de los Huesos (SH) site of the Sierra de Atapuerca (Burgos, Spain). As expected, this pattern is similar to that of modern humans. A delay of development of the lower and upper canines was observed. In contrast, the relative advanced development of the lower second molars and, especially, the upper and lower third molars is noteworthy. This latter feature seems to be common in Pleistocene hominids, and suggests that the pattern of dental development evolved in the genus Homo during the Pleistocene. In European Middle Pleistocene hominids, this pattern probably was facilitated by the extra space available in the mandible and maxilla for developing teeth.

    2016-01-01

    At a fundamental level, the classical picture of the world is dead, and has been dead now for almost a century. Pinning down exactly which quantum phenomena are responsible for this has proved to be a tricky and controversial question, but a lot of progress has been made in the past few decades. We now have a range of precise statements showing that whatever the ultimate laws of nature are, they cannot be classical. In this article, we review results on the fundamental phenomena of quantum theory that cannot be understood in classical terms. We proceed by first granting quite a broad notion of classicality, describe a range of quantum phenomena (such as randomness, discreteness, the indistinguishability of states, measurement-uncertainty, measurement-disturbance, complementarity, non-commutativity, interference, the no-cloning theorem and the collapse of the wave-packet) that do fall under its liberal scope, and then finally describe some aspects of quantum physics that can never admit a classical understanding - the intrinsically quantum mechanical aspects of nature. The most famous of these is Bell's theorem, but we also review two more recent results in this area. Firstly, Hardy's theorem shows that even a finite-dimensional quantum system must contain an infinite amount of information, and secondly, the Pusey-Barrett-Rudolph theorem shows that the wave function must be an objective property of an individual quantum system. Besides being of foundational interest, results of this sort now find surprising practical applications in areas such as quantum information science and the simulation of quantum systems.

    The article is dedicated to discussion of irreversibility and foundation of statistical mechanics "from the first principles". Taking into account infinitesimal and, as it seems, neglectful for classical mechanics fluctuations of the physical vacuum, makes a deterministic motion of unstable dynamic systems is broken ("spontaneous determinism breaking", "spontaneous stochastization"). Vacuum fluctuations play part of the trigger, starting the powerful mechanism of exponent instability. The motion of the dynamic systems becomes irreversible and stochastic. Classical mechanics turns out to be applicable only for a small class of stable dynamic systems with zero Kolmogorov-Sinay entropy $h=0$. For alternative "Stochastic mechanics" there are corresponding equations of motion and Master Equation, describing irreversible evolution of the initial distribution function to equilibrium state.

    2011-01-01

    It is pointed out that the noncloning theorem in quantum mechanics also holds for unknown state in linear classical physics. The apparent capability of copying of a classical state is essentially the capability of perfect measurement in classical physics. The difference in copying between quantum and classical physics is the difference in measurement between the two theories. A classical copying process is the combined action of measurement of an unknown state and the preparation of this state onto another system. Hence perfect measurability in classical physics enables the copying of a classical state.

    The origin of the phenomenological deterministic laws that approximately govern the quasiclassical domain of familiar experience is considered in the context of the quantum mechanics of closed systems such as the universe as a whole. We investigate the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e. such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones. We discuss these requirements generally but study them specifically for coarse grainings of the type that follows a distinguished subset of a complete set of variables while ignoring the rest. More coarse graining is needed to achieve decoherence than would be suggested by naive arguments based on the uncertainty principle. Even coarser graining is required in the distinguished variables for them to have the necessary inertia to approach classical predictability in the presence of t...

  8. Classical databases and knowledge organization

    DEFF Research Database (Denmark)

    Hjørland, Birger

    2015-01-01

    This paper considers classical bibliographic databases based on the Boolean retrieval model (such as MEDLINE and PsycInfo). This model is challenged by modern search engines and information retrieval (IR) researchers, who often consider Boolean retrieval a less efficient approach. The paper...... examines this claim and argues for the continued value of Boolean systems, which suggests two further considerations: (1) the important role of human expertise in searching (expert searchers and “information literate” users) and (2) the role of library and information science and knowledge organization (KO......) in the design and use of classical databases. An underlying issue is the kind of retrieval system for which one should aim. Warner’s (2010) differentiation between the computer science traditions and an older library-oriented tradition seems important; the former aim to transform queries automatically...

  9. From classical to quantum physics

    CERN Document Server

    Stehle, Philip

    2017-01-01

    Suitable for lay readers as well as students, this absorbing survey explores the twentieth-century transition from classical to quantum physics. Author Philip Stehle traces the shift in the scientific worldview from the work of Galileo, Newton, and Darwin to the modern-day achievements of Max Planck, Albert Einstein, Ernest Rutherford, Niels Bohr, and others of their generation. His insightful overview examines not only the history of quantum physics but also the ways that progress in the discipline changed our understanding of the physical world and forces of nature. This chronicle of the second revolution in the physical sciences conveys the excitement and suspense that new developments produced in the scientific community. The narrative ranges from the classical physics of the seventeenth-century to the emergence of quantum mechanics with the entrance of the electron, the rise of relativity theory, the development of atomic theory, and the recognition of wave-particle duality. Relevant mathematical details...

  10. Quantum Models of Classical World

    Directory of Open Access Journals (Sweden)

    Petr Hájíček

    2013-02-01

    Full Text Available This paper is a review of our recent work on three notorious problems of non-relativistic quantum mechanics: realist interpretation, quantum theory of classical properties, and the problem of quantum measurement. A considerable progress has been achieved, based on four distinct new ideas. First, objective properties are associated with states rather than with values of observables. Second, all classical properties are selected properties of certain high entropy quantum states of macroscopic systems. Third, registration of a quantum system is strongly disturbed by systems of the same type in the environment. Fourth, detectors must be distinguished from ancillas and the states of registered systems are partially dissipated and lost in the detectors. The paper has two aims: a clear explanation of all new results and a coherent and contradiction-free account of the whole quantum mechanics including all necessary changes of its current textbook version.

  11. Classical Corrections in String Cosmology

    CERN Document Server

    Brustein, Ram; Brustein, Ram; Madden, Richard

    1999-01-01

    An important element in a model of non-singular string cosmology is a phase in which classical corrections saturate the growth of curvature in a deSitter-like phase with a linearly growing dilaton (an `algebraic fixed point'). As the form of the classical corrections is not well known, here we look for evidence, based on a suggested symmetry of the action, scale factor duality and on conformal field theory considerations, that they can produce this saturation. It has previously been observed that imposing scale factor duality on the $O(\\alpha')$ corrections is not compatible with fixed point behavior. Here we present arguments that these problems persist to all orders in $\\alpha'$. We also present evidence for the form of a solution to the equations of motion using conformal perturbation theory, examine its implications for the form of the effective action and find novel fixed point structure.

  12. Potential Theory in Classical Electrodynamics

    Engelhardt, Wolfgang

    2012-01-01

    In Maxwell's classical theory of electrodynamics the fields are frequently expressed by potentials in order to facilitate the solution of the first order system of equations. This method obscures, however, that there exists an inconsistency between Faraday's law of induction and Maxwell's flux law. As a consequence of this internal contradiction there is neither gauge invariance, nor exist unique solutions in general. It is also demonstrated that inhomogeneous wave equations cannot be solved by retarded integrals.

    2010-01-01

    This study introduces a new signal analysis method called SCSA, based on a semi-classical approach. The main idea in the SCSA is to interpret a pulse-shaped signal as a potential of a Schr\\"odinger operator and then to use the discrete spectrum of this operator for the analysis of the signal. We present some numerical examples and the first results obtained with this method on the analysis of arterial blood pressure waveforms.

    Hohmann, Manuel; Wohlfarth, Mattias N R

    2008-01-01

    We propose a mathematical model of quantum spacetime as an infinite-dimensional manifold locally homeomorphic to an appropriate Schwartz space. This extends and unifies both the standard function space construction of quantum mechanics and the manifold structure of spacetime. In this picture we demonstrate that classical spacetime emerges as a finite-dimensional manifold through the topological identification of all quantum points with identical position expectation value. We speculate on the possible relevance of this geometry to quantum field theory and gravity.

The nearly 300 problems and exercises range from simple applications to open problems. Exercises are embedded in the text as essential parts of the exposition. Problems are collected at the end of each chapter; solutions to select problems are given at the end of the book. Mathematica®, Matlab™, and Xfig are used to illustrate selected concepts and results. The careful selection of results serves to show the reader how to prove the most important theorems in the subject, which may become the foundation of future progress...

  18. Bayesian signal processing classical, modern, and particle filtering methods

    CERN Document Server

    Candy, James V

    2016-01-01

    This book aims to give readers a unified Bayesian treatment starting from the basics (Baye's rule) to the more advanced (Monte Carlo sampling), evolving to the next-generation model-based techniques (sequential Monte Carlo sampling). This next edition incorporates a new chapter on "Sequential Bayesian Detection," a new section on "Ensemble Kalman Filters" as well as an expansion of Case Studies that detail Bayesian solutions for a variety of applications. These studies illustrate Bayesian approaches to real-world problems incorporating detailed particle filter designs, adaptive particle filters and sequential Bayesian detectors. In addition to these major developments a variety of sections are expanded to "fill-in-the gaps" of the first edition. Here metrics for particle filter (PF) designs with emphasis on classical "sanity testing" lead to ensemble techniques as a basic requirement for performance analysis. The expansion of information theory metrics and their application to PF designs is fully developed an...

  19. Psychology of the scientist: LXXXII. Coverage of classical conditioning in textbooks in the psychology of learning, 1952-1995.

    Science.gov (United States)

    Coleman, S R; Fanelli, A; Gedeon, S

    2000-06-01

    Objective information was obtained from 89 textbooks in the psychology of learning published from 1952 through 1995 to answer questions about their coverage of classical conditioning. We found (a) that classical conditioning consistently received less coverage than instrumental and operant conditioning, (b) that the distinction of classical and instrumental conditioning has become established as a textbook-construction device, (c) that use of the classical-instrumental distinction by textbook authors has "hardened" after a period of "fluidity" in the 1970s, (d) that the currency of references in the basic classical (as well as instrumental) conditioning chapters diminished from 1952 to 1995. Findings are discussed in regard to the possibility that, as a class, and in comparison to other textbooks, the textbooks of the psychology of learning fall short of fulfilling some of their recognized roles.

  20. Quantum-Classical Correspondence: Dynamical Quantization and the Classical Limit

    Energy Technology Data Exchange (ETDEWEB)

    Turner, L [Los Alamos National Laboratory, Los Alamos, NM 87545 (United States)

    2004-11-12

    In only 150 pages, not counting appendices, references, or the index, this book is one author's perspective of the massive theoretical and philosophical hurdles in the no-man's-land separating the classical and quantum domains of physics. It ends with him emphasizing his own theoretical contribution to this area. In his own words, he has attempted to answer: 1. How can we obtain the quantum dynamics of open systems initially described by the equations of motion of classical physics (quantization process) 2. How can we retrieve classical dynamics from the quantum mechanical equations of motion by means of a classical limiting process (dequantization process). However, this monograph seems overly ambitious. Although the publisher's description refers to this book as an accessible entre, we find that this author scrambles too hastily over the peaks of information that are contained in his large collection of 272 references. Introductory motivating discussions are lacking. Profound ideas are glossed over superficially and shoddily. Equations morph. But no new convincing understanding of the physical world results. The author takes the viewpoint that physical systems are always in interaction with their environment and are thus not isolated and, therefore, not Hamiltonian. This impels him to produce a method of quantization of these stochastic systems without the need of a Hamiltonian. He also has interest in obtaining the classical limit of the quantized results. However, this reviewer does not understand why one needs to consider open systems to understand quantum-classical correspondence. The author demonstrates his method using various examples of the Smoluchowski form of the Fokker--Planck equation. He then renders these equations in a Wigner representation, uses what he terms an infinitesimality condition, and associates with a constant having the dimensions of an action. He thereby claims to develop master equations, such as the Caldeira

  1. Quantum Transitions Between Classical Histories: Bouncing Cosmologies

    CERN Document Server

    Hartle, James

    2015-01-01

    In a quantum theory of gravity spacetime behaves classically when quantum probabilities are high for histories of geometry and field that are correlated in time by the Einstein equation. Probabilities follow from the quantum state. This quantum perspective on classicality has important implications: (a) Classical histories are generally available only in limited patches of the configuration space on which the state lives. (b) In a given patch states generally predict relative probabilities for an ensemble of possible classical histories. (c) In between patches classical predictability breaks down and is replaced by quantum evolution connecting classical histories in different patches. (d) Classical predictability can break down on scales well below the Planck scale, and with no breakdown in the classical equations of motion. We support and illustrate (a)-(d) by calculating the quantum transition across the de Sitter like throat connecting asymptotically classical, inflating histories in the no-boundary quantu...

  2. Intuitionism vs. classicism a mathematical attack on classical logic

    CERN Document Server

    Haverkamp, Nick

    2015-01-01

    In the early twentieth century, the Dutch mathematician L.E.J. Brouwer launched a powerful attack on the prevailing mathematical methods and theories. He developed a new kind of constructive mathematics, called intuitionism, which seems to allow for a rigorous refutation of widely accepted mathematical assumptions including fundamental principles of classical logic. Following an intense mathematical debate esp. in the 1920s, Brouwer's revolutionary criticism became a central philosophical concern in the 1970s, when Michael Dummett tried to substantiate it with meaning-theoretic considerations.

    In this chapter, we illustrate benefits of thinking in terms of thread management techniques when using a centralized scheduler model along with interoperability of MPI and PThread. This is facilitated through an exploration of thread placement strategies for an algorithm modeling radiative heat transfer with special attention to the 61st core. This algorithm plays a key role within the Uintah Computational Framework (UCF) and current efforts taking place at the University of Utah to model next-generation, large-scale clean coal boilers. In such simulations, this algorithm models the dominant form of heat transfer and consumes a large portion of compute time. Exemplified by a real-world example, this chapter presents our early efforts in porting a key portion of a scalability-centric codebase to the Intel Xeon Phi coprocessor. Specifically, this chapter presents results from our experiments profiling the native execution of a reverse Monte-Carlo ray tracing-based radiation model on a single coprocessor. These results demonstrate that our fastest run configurations utilized the 61st core and that performance was not profoundly impacted when explicitly oversubscribing the coprocessor operating system thread. Additionally, this chapter presents a portion of radiation model source code, a MIC-centric UCF cross-compilation example, and less conventional thread management technique for developers utilizing the PThreads threading model.

  12. The Relation between Classical and Quantum Electrodynamics

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Quantum electrodynamics presents intrinsic limitations in the description of physical processes that make it impossible to recover from it the type of description we have in classical electrodynamics. Hence one cannot consider classical electrodynamics as reducing to quantum electrodynamics and being recovered from it by some sort of limiting procedure. Quantum electrodynamics has to be seen not as an more fundamental theory, but as an upgrade of classical electrodynamics, which permits an extension of classical theory to the description of phenomena that, while being related to the conceptual framework of the classical theory, cannot be addressed from the classical theory.

    Directory of Open Access Journals (Sweden)

    Konstantin D. BUGROV

    2016-01-01

    Full Text Available The paper deals with the issue of functioning of the legal political language in Russian public thought of XVIII century. The author demonstrates that for XVIII century Russian elites legal categories were inferior in comparison with the moral categories of the political analysis. The Russian political culture was dominated by the court communication sphere with panegyric, manifesto and report as its main genres and therefore was not sensitive to the theories of natural law and contractualism, staying closer to moralism of Leibniz rather than natural law jurisprudence of Pufendorf. However, in Russia the court political discourse also embraced the idea of miracle, a direct intervention of Providence into the political life, which reflected in the legitimation of several palace coups. The court elites were treating the law as a classification of administrative regulations and the necessity of punishing the vices and rewarding the virtues, just as Godly justice did. In turn, the growing public sphere also had little interest in the juridical glossaries, preferring to debate the moral, historical and economic texts. The author concludes that the weakness of the juridical doctrines in XVIII century Russia was conditioned by the specifics of Russian political system.

    In this thesis, the numerical simulation of strongly-interacting many-body quantum-mechanical systems using matrix product states (MPS) is considered. Matrix-Product-States are a novel representation of arbitrary quantum many-body states. Using quantum information theory, it is possible to show that Matrix-Product-States provide a polynomial-sized representation of one-dimensional quantum systems, thus allowing an efficient simulation of one-dimensional quantum system on classical computers. Matrix-Product-States form the conceptual framework of the density-matrix renormalization group (DMRG). After a general introduction in the first chapter of this thesis, the second chapter deals with Matrix-Product-States, focusing on the development of fast and stable algorithms. To obtain algorithms to efficiently calculate ground states, the density-matrix renormalization group is reformulated using the Matrix-Product-States framework. Further, time-dependent problems are considered. Two different algorithms are presented, one based on a Trotter decomposition of the time-evolution operator, the other one on Krylov subspaces. Finally, the evaluation of dynamical spectral functions is discussed, and a correction vector-based method is presented. In the following chapters, the methods presented in the second chapter, are applied to a number of different physical problems. The third chapter deals with the existence of chiral phases in isotropic one-dimensional quantum spin systems. A preceding analytical study based on a mean-field approach indicated the possible existence of those phases in an isotropic Heisenberg model with a frustrating zig-zag interaction and a magnetic field. In this thesis, the existence of the chiral phases is shown numerically by using Matrix-Product-States-based algorithms. In the fourth chapter, we propose an experiment using ultracold atomic gases in optical lattices, which allows a well controlled observation of the spin-charge separation (of

    2003-01-01

    The problem of inter-band tunneling in a semiconductor (Zener breakdown) in a nonstationary and homogeneous electric field is solved exactly. Using the exact analytical solution, the approximation based on classical trajectories is studied. A new mechanism of enhanced tunneling through static non-one-dimensional barriers is proposed in addition to well known normal tunneling solely described by a trajectory in imaginary time. Under certain conditions on the barrier shape and the particle energy, the probability of enhanced tunneling is not exponentially small even for non-transparent barriers, in contrast to the case of normal tunneling.

  17. Motions of Classical Charged Tachyons

    CERN Document Server

    Davidson, M P

    2001-01-01

    It is shown by numerical simulation that classical charged tachyons have self-orbiting helical solutions in a narrow neighborhood of certain discrete values for the velocity when the electromagnetic interaction is described by Feynman-Wheeler electrodynamics. The force rapidly oscillates between attractive and repulsive as a function of velocity in this neighborhood. Causal electrodynamics is also considered, and in this case it is found that when the force is attractive the tachyon loses energy to radiation. Only certain narrow ranges of velocity give attractive forces, and a geometrical derivation of these special velocities is given. Possible implications of these results for hidden variable theories of quantum mechanics are conjectured.

    This review of solar physics emphasizes several of the more conspicuous scientific puzzles posed by contemporary observational knowledge of the magnetic activity of the Sun. The puzzles emphasize how much classical physics we have yet to learn from the Sun. The physics of solar activity is based on the principles of Newton, Maxwell, Lorentz, Boltzmann, et. al., along with the principles of radiative transfer. In the large, these principles are expressed by magnetohydrodynamics. A brief derivation of the magnetohydrodynamic induction and momentum equations is provided, with a discussion of popular misconceptions.

In standard Quantum Mechanics only the wave function or the results of measurements exist, and to answer the question of how the classical world can be part of the quantum world is a rather formidable task. However, this is not the case for Bohmian mechanics, which, like classical mechanics, is a theory about real objects. In Bohmian terms, the problem of the classical limit be...

    Successful management of classical ballet dancers with overuse injuries requires an understanding of the art form, precise knowledge of anatomy and awareness of certain conditions. Turnout is the single most fundamental physical attribute in classical ballet and 'forcing turnout' frequently contributes to overuse injuries. Common presenting conditions arising from the foot and ankle include problems at the first metatarsophalangeal joint, second metatarsal stress fractures, flexor hallucis longus tendinitis and anterior and posterior ankle impingement syndromes. Persistent shin pain in dancers is often due to chronic compartment syndrome, stress fracture of the posteromedial or anterior tibia. Knee pain can arise from patellofemoral syndrome, patellar tendon insertional pathologies, or a combination of both. Hip and back problems are also prevalent in dancers. To speed injury recovery of dancers, it is important for the sports medicine team to cooperate fully. This permits the dancer to benefit from accurate diagnosis, technique correction where necessary, the full range of manual therapies to joint and soft tissue, appropriate strengthening programmes and maintenance of dance fitness during any time out of class with Pilates-based exercises and nutrition advice. Most overuse ballet conditions respond well to a combination of conservative therapies. Those dancers that do require surgical management still depend heavily on ballet-specific rehabilitation for a complete recovery.

    The origin of the phenomenological deterministic laws that approximately govern the quasiclassical domain of familiar experience is considered in the context of the quantum mechanics of closed systems such as the universe as a whole. A formulation of quantum mechanics is used that predicts probabilities for the individual members of a set of alternative coarse-grained histories that [ital decohere], which means that there is negligible quantum interference between the individual histories in the set. We investigate the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e., such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones. We discuss these requirements generally but study them specifically for coarse grainings of the type that follows a distinguished subset of a complete set of variables while ignoring the rest. More coarse graining is needed to achieve decoherence than would be suggested by naive arguments based on the uncertainty principle. Even coarser graining is required in the distinguished variables for them to have the necessary inertia to approach classical predictability in the presence of the noise consisting of the fluctuations that typical mechanisms of decoherence produce. We describe the derivation of phenomenological equations of motion explicitly for a particular class of models.

    The aerobic and anaerobic energy yield during professional training sessions ("classes") of classical ballet as well as during rehearsed and performed ballets has been studied by means of oxygen uptake, heart rate, and blood lactate concentration determinations on professional ballet dancers from the Royal Swedish Ballet in Stockholm. The measured oxygen uptake during six different normal classes at the theatre averaged about 35-45% of the maximal oxygen uptake, and the blood lactate concentration averaged 3 mM (N = 6). During 10 different solo parts of choreographed dance (median length = 1.8 min) representative for moderately to very strenuous dance, an average oxygen uptake (measured during the last minute) of 80% of maximum and blood lactate concentration of 10 mM was measured (N = 10). In addition, heart rate registrations from soloists in different ballets during performance and final rehearsals frequently indicated a high oxygen uptake relative to maximum and an average blood lactate concentration of 11 mM (N = 5). Maximal oxygen uptake, determined in 1971 (N = 11) and 1983 (N = 13) in two different groups of dancers, amounted to on the average 51 and 56 ml X min-1 X kg-1 for the females and males, respectively. In conclusion, classical ballet is a predominantly intermittent type of exercise. In choreographed dance each exercise period usually lasts only a few minutes, but can be very demanding energetically, while during the dancers' basic training sessions, the energy yield is low.

  9. Classical Black Holes Are Hot

    Curiel, Erik

    2014-01-01

    In the early 1970s it is was realized that there is a striking formal analogy between the Laws of black-hole mechanics and the Laws of classical thermodynamics. Before the discovery of Hawking radiation, however, it was generally thought that the analogy was only formal, and did not reflect a deep connection between gravitational and thermodynamical phenomena. It is still commonly held that the surface gravity of a stationary black hole can be construed as a true physical temperature and its area as a true entropy only when quantum effects are taken into account; in the context of classical general relativity alone, one cannot cogently construe them so. Does the use of quantum field theory in curved spacetime offer the only hope for taking the analogy seriously? I think the answer is `no'. To attempt to justify that answer, I shall begin by arguing that the standard argument to the contrary is not physically well founded, and in any event begs the question. Looking at the various ways that the ideas of "tempe...

  10. Fluctuations in classical sum rules.

    2010-10-01

    Classical sum rules arise in a wide variety of physical contexts. Asymptotic expressions have been derived for many of these sum rules in the limit of long orbital period (or large action). Although sum-rule convergence may well be exponentially rapid for chaotic systems in a global phase-space sense with time, individual contributions to the sums may fluctuate with a width which diverges in time. Our interest is in the global convergence of sum rules as well as their local fluctuations. It turns out that a simple version of a lazy baker map gives an ideal system in which classical sum rules, their corrections, and their fluctuations can be worked out analytically. This is worked out in detail for the Hannay-Ozorio sum rule. In this particular case the rate of convergence of the sum rule is found to be governed by the Pollicott-Ruelle resonances, and both local and global boundaries for which the sum rule may converge are given. In addition, the width of the fluctuations is considered and worked out analytically, and it is shown to have an interesting dependence on the location of the region over which the sum rule is applied. It is also found that as the region of application is decreased in size the fluctuations grow. This suggests a way of controlling the length scale of the fluctuations by considering a time dependent phase-space volume, which for the lazy baker map decreases exponentially rapidly with time.

    A new classical, non singular solution with arbitrarily low energy is found for SU(2) non abelian fields in the presence of a static charge. Physically it means that a classical charge coupled to any SU(N) non abelian gauge field will develop a pure gauge field, carrying no energy, that will completely screen it - there are no visible classical non abelian charges.

    2016-01-01

    This chapter enumerates the steps required in designing and planning field studies on the ecology and conservation of reptiles, as these involve a high level of uncertainty and risk. To this end, the chapter differentiates between goals (descriptions of what one intends to accomplish) and objectives (the measurable steps required to achieve the established goals). Thus, meeting a specific goal may require many objectives. It may not be possible to define some of them until certain experiments have been conducted; often evaluations of sampling protocols are needed to increase certainty in the biological results. And if sampling locations are fixed and sampling events are repeated over time, then both study-specific covariates and sampling-specific covariates should exist. Additionally, other critical design considerations for field study include obtaining permits, as well as researching ethics and biosecurity issues.

  4. Inflation and classical scale invariance

    CERN Document Server

    Racioppi, Antonio

    2014-01-01

    BICEP2 measurement of primordial tensor modes in CMB suggests that cosmological inflation is due to a slowly rolling inflaton taking trans-Planckian values and provides further experimental evidence for the absence of large $M_{\\rm P}$ induced operators. We show that classical scale invariance solves the problem and allows for a remarkably simple scale-free inflaton model without any gauge group. Due to trans-Planckian inflaton values and VEVs, a dynamically induced Coleman-Weinberg-type inflaton potential of the model can predict tensor-to-scalar ratio $r$ in a large range. Precise determination of $r$ in future experiments will allow to test the proposed field-theoretic framework.

  5. A Classical Model of Gravitation

    Directory of Open Access Journals (Sweden)

    Wagener P.

    2008-07-01

    Full Text Available A classical model of gravitation is proposed with time as an independent coordinate. The dynamics of the model is determined by a proposed Lagrangian. Applying the canonical equations of motion to its associated Hamiltonian gives conservation equa- tions of energy, total angular momentum and the z component of the angular momen- tum. These lead to a Keplerian orbit in three dimensions, which gives the observed values of perihelion precession and bending of light by a massive object. An expression for gravitational redshift is derived by accepting the local validity of special relativity at all points in space. Exact expressions for the GEM relations, as well as their associated Lorentz-type force, are derived. An expression for Mach’s Principle is also derived.

  6. Classical electromagnetism in a nutshell

    CERN Document Server

    Garg, Anupam

    2012-01-01

    This graduate-level physics textbook provides a comprehensive treatment of the basic principles and phenomena of classical electromagnetism. While many electromagnetism texts use the subject to teach mathematical methods of physics, here the emphasis is on the physical ideas themselves. Anupam Garg distinguishes between electromagnetism in vacuum and that in material media, stressing that the core physical questions are different for each. In vacuum, the focus is on the fundamental content of electromagnetic laws, symmetries, conservation laws, and the implications for phenomena such as radiation and light. In material media, the focus is on understanding the response of the media to imposed fields, the attendant constitutive relations, and the phenomena encountered in different types of media such as dielectrics, ferromagnets, and conductors. The text includes applications to many topical subjects, such as magnetic levitation, plasmas, laser beams, and synchrotrons.

    Galley, Chad R

    2013-04-26

    Hamilton's principle of stationary action lies at the foundation of theoretical physics and is applied in many other disciplines from pure mathematics to economics. Despite its utility, Hamilton's principle has a subtle pitfall that often goes unnoticed in physics: it is formulated as a boundary value problem in time but is used to derive equations of motion that are solved with initial data. This subtlety can have undesirable effects. I present a formulation of Hamilton's principle that is compatible with initial value problems. Remarkably, this leads to a natural formulation for the Lagrangian and Hamiltonian dynamics of generic nonconservative systems, thereby filling a long-standing gap in classical mechanics. Thus, dissipative effects, for example, can be studied with new tools that may have applications in a variety of disciplines. The new formalism is demonstrated by two examples of nonconservative systems: an object moving in a fluid with viscous drag forces and a harmonic oscillator coupled to a dissipative environment.

    The rainbow, the moon, a spinning top, a comet, the ebb and flood of the oceans ...a falling apple. There is only one universe and it fell to Isaac Newton to discover its secrets. Newton was arguably the greatest scientific genius of all time, and yet he remains a mysterious figure. Written and illustrated by William Rankin, "Introducting Newton and Classical Physics" explains the extraordinary ideas of a man who sifted through the accumulated knowledge of centuries, tossed out mistaken beliefs, and single-handedly made enormous advances in mathematics, mechanics and optics. By the age of 25, entirely self-taught, he had sketched out a system of the world. Einstein's theories are unthinkable without Newton's founding system. He was also a secret heretic, a mystic and an alchemist, the man of whom Edmund Halley said "Nearer to the gods may no man approach!". This is an ideal companion volume to "Introducing Einstein".

  9. Scientific Realism and Classical Physics

    2008-01-01

    We recount the successful long career of classical physics, from Newton to Einstein, which was based on the philosophy of scientific realism. Special emphasis is given to the changing status and number of ontological entitities and arguments for their necessity at any time. Newton, initially, began with (i) point particles, (ii) aether, (iii) absolute space and (iv) absolute time. The electromagnetic theory of Maxwell and Faraday introduced `fields' as a new ontological entity not reducible to earlier ones. Their work also unified electricity, magnetism and optics. Repeated failure to observe the motion of earth through aether led Einstein to modify the Newtonian absolute space and time concepts to a fused Minkowski space-time and the removal of aether from basic ontological entities in his special theory of relativity. Later Einstein in his attempts to give a local theory of gravitation was led to further modify flat Minkowski space-time to the curved Riemannian space time. This reduced gravitational phenome...

    2002-12-30

    We study planar classical scattering from an oscillating heavy target whose dynamics defines a five-dimensional phase space. Although the system possesses no periodic orbits, and thus topological chaos is not present, the scattering functions display a variety of structures on different time scales. These structures are due to scattering events with a strong energy transfer from the projectile to the moving disk resulting in low-velocity peaks. We encounter initial conditions for which the projectile exhibits infinitely many bounces with the oscillating disk. Our numerical investigations are supported by analytical results on a specific model with a simple time-law. The observed properties possess universal character for scattering off oscillating targets.

The investigation was carried out in two stages: one, description in which 106 dancers participated; the other, causal comparative in which 50 dancers participated; and (a questionnaire; (b a checkerboard; (c postural chart; (d measure tape; (e camera and (f pedoscope were used as instrument. Descriptive and inferential statistics was used for analysis. The results revealed the most frequent postural changes such as hyperlordosis, unleveled shoulders and pronated ankles. Ballet seems to have negative implications in the postural development , affecting especially the vertebral spine, trunk and feet. The practice time was not a parameter to indicate the increase in postural changes. In conclusion, ballet may be associated with postural changes and determining a characteristic postural pattern.

    Lai, Kent; Boxer, Matthew B; Marabotti, Anna

    2014-06-01

    Classic galactosemia is an inherited metabolic disease for which, at present, no therapy is available apart from galactose-restricted diet. However, the efficacy of the diet is questionable, since it is not able to prevent the insurgence of chronic complications later in life. In addition, it is possible that dietary restriction itself could induce negative side effects. Therefore, there is a need for an alternative therapeutic approach that can avert the manifestation of chronic complications in the patients. In this review, the authors describe the development of a novel class of pharmaceutical agents that target the production of a toxic metabolite, galactose-1-phosphate, considered as the main culprit for the cause of the complications, in the patients.

    Classic galactosemia (CG) is an autosomal recessive disorder of galactose metabolism that affects approximately 1/50,000 live births in the USA. Following exposure to milk, which contains large quantities of galactose, affected infants may become seriously ill. Early identification by newborn screening with immediate dietary galactose restriction minimizes or prevents the potentially lethal acute symptoms of CG. However, more than half of individuals with CG still experience long-term complications including cognitive disability, behavioral problems, and speech impairment. Anecdotal reports have also suggested frequent gastrointestinal (GI) problems, but this outcome has not been systematically addressed. In this study we explored the prevalence of GI symptoms among 183 children and adults with CG (cases) and 190 controls. Cases reported 4.5 times more frequent constipation (95% CI 1.8-11.5) and 4.2 times more frequent nausea (95% CI 1.2-15.5) than controls. Cases with genotypes predicting residual GALT activity reported less frequent constipation than cases without predicted GALT activity but this difference was not statistically significant. Because the rigor of dietary galactose restriction varies among individuals with galactosemia, we further tested whether GI symptoms associated with diet in infancy. Though constipation was almost four times as common among cases reporting a more restrictive diet in infancy, this difference was not statistically significant. These data confirm that certain GI symptoms are more common in classic galactosemia compared to controls and suggest that future studies should investigate associations with residual GALT activity and dietary galactose restriction in early life.

    Full Text Available The numerous hospitals in existence in the city of Zamora in the Middle Ages were considerably streamlined in the Early Modern Era. The foundation of the Sotelo hospital in the 16th century and the La Encarnación hospital in the 17th century endowed the city with two main centres offering medical and health care. This study focused on an analysis of the patients who received care at the La Encarnación hospital, which was governed by the City Council and the Cathedral Chapter. A patient profile was constructed from admission and mortality records, depending on the case. However, the main focus was an analysis of the hospital’s area of influence, which was found to amply exceed its immediate geographical context.El gran número de hospitales que tuvo la ciudad de Zamora durante la Edad Media quedó notablemente simplificado en la época Moderna. La fundación en el siglo XVI del hospital de Sotelo y en el XVII de La Encarnación, supuso dotar a la ciudad con dos importantes centros que ofrecía atención médico-sanitaria. Este trabajo está centrado en el de La Encarnación, entre cuyos administradores se hallaban el Ayuntamiento y el Cabildo de la Catedral, y el objeto de análisis han sido los asistidos. A partir de los registros de ingreso y defunciones, dependiendo del momento, hemos trazado el perfil de los mismos, pero, sobre todo, nos hemos centrado en el radio de influencia del establecimiento, que, como hemos podido comprobar, superaba ampliamente el marco geográfico de emplazamiento.

  16. Hilbert space theory of classical electrodynamics

    RAJAGOPAL A K; GHOSE PARTHA

    2016-06-01

    Classical electrodynamics is reformulated in terms of wave functions in the classical phase space of electrodynamics, following the Koopman–von Neumann–Sudarshan prescription for classical mechanics on Hilbert spaces sans the superselection rule which prohibits interference effects in classical mechanics. This is accomplished by transforming from a set of commutingobservables in one Hilbert space to another set of commuting observables in a larger Hilbert space. This is necessary to clarify the theoretical basis of the much recent work on quantum-like features exhibited by classical optics. Furthermore, following Bondar et al, {\\it Phys. Rev.} A 88, 052108 (2013), it is pointed out that quantum processes that preserve the positivity or nonpositivity of theWigner function can be implemented by classical optics. This may be useful in interpreting quantum information processing in terms of classical optics.

    Full Text Available A lo largo del sigloXVIII, en diversas catedrales novohispanas se plan-teó el problema de los rituales propios de los vicepatronos, en particu-lar durante las solemnidades del Jueves Santo. Este tema fue abordadosólo de manera indirecta y ambigua en la legislación civil. Losreformadores borbónicos no se decidieron a establecer reglas fijaspara él, por lo que estuvo fuertemente marcado por la diversidad decostumbres locales. Así, se introdujeron prácticas como la demostra-ción de la Eucaristía antes de su depósito o la entrega de la llave delSagrario a los vicepatronos. Los obispos de la época, aunque fielessúbditos de la Corona, trataron de limitar en lo posible su intervenciónen unas ceremonias que estimaban sagradas. Se fue construyendo asíel ceremonial que heredarían los primeros gobiernos republicanos.

    Full Text Available El artículo se refiere al Epistolario de una monja chilena del siglo XVIII, sor Josefa de los Dolores Peña y Lillo, y se centra en la consideración de la imagen mística de la "bodega del amor" que en el texto se transforma en "retrete del amor". A propósito de ello, se establece la vinculación del Epistolario con la tradición de la literatura mística española y se proponen sentidos para el relieve de lo íntimo y privado que esa transformación confiere a la imagen mística tradicionalThis article refers to the Epistolary of a Chilean nun of the 18th Century, Sister Josefa de los Dolores Peña y Lillo. It centers on the consideration of the mystical image of the "Love's storeroom", which in the text is transformed into the "Love privy". In relation to it, a link between the Epistolary and the tradition of the Spanish mystical literature is discussed, while different senses are suggested for the highlighting of the private and intimate which that transformation confers upon the traditional mystical image

    Full Text Available Partiendo de un análisis de las dimensiones del reformismo en el virreinato novohispano a través de la amplia bibliografía cubriendo casi todo el siglo XVIII completo, este estudio analiza las dimensiones políticas del reformismo en sus distintas fases, desde Felipe V hasta Carlos IV. Insistiendo particularmente en el período de la visita de José de Gálvez, el estudio parte de la hipótesis de que los conflictos en torno a estas reformas versan en el fondo sobre si debería continuar el régimen imperial, heredado del período de los habsburgos y condensada en órden legal en la Recopilación de las Leyes de Indias de 1680/1, o si la cohesión de la monarquía transatlántica exigía el cambio a un régimen de gobierno territorial. A pesar de las reformas de Carlos III y sus ministros, el dilema se mantiene hasta el final del siglo y explica en gran medida que, a pesar del cúmulo de reformas, nunca se decide de forma clara esta alternativa subyacente de las reformas.

    Extracellular matrix and soluble plasma proteins generate peptides that regulate biological activities such as cell growth, differentiation and migration. Bradykinin, a peptide released from kininogen by kallikreins, stimulates vasodilatation and endothelial cell proliferation. Various classes of substances can potentiate these biological actions of bradykinin. Among them, the best studied are bradykinin potentiating peptides (BPPs) derived from snake venom, which can also strongly inhibit angiotensin I-converting enzyme (ACE) activity. We identified and synthesized sequences resembling BPPs in the vicinity of potential proteolytic cleavage sites in the collagen XVIII molecule, close to endostatin. These peptides were screened as inhibitors of human recombinant wild-type ACE containing two intact functional domains; two full-length ACE mutants containing only a functional C- or N-domain catalytic site; and human testicular ACE, a natural form of the enzyme that only contains the C-domain. The BPP-like peptides inhibited ACE in the micromolar range and interacted preferentially with the C-domain. The proteolytic activity involved in the release of BPP-like peptides was studied in human serum and human umbilical-vein endothelial cells. The presence of enzymes able to release these peptides in blood led us to speculate on a physiological mechanism for the control of ACE activities.

    Full Text Available El presente trabajo se centra en el análisis de los conflictos que giraron en torno a las operaciones de compra de esclavos en el nororiente neogranadino durante el siglo XVIII. Legalizaciones aplazadas, ventas desautorizadas, pagos pendientes, esclavos hipotecados y confusiones sobre el estado real del esclavo comercializado fueron situaciones que desataron enconadas disputas y pleitos judiciales que terminaron algunas veces con la declaratoria de redhibitoria, es decir, la anulación del contrato de venta y la devolución del esclavo. En vista de estos antecedentes, y con un ánimo preventivo, los negociantes se aseguraron de fijar en las escrituras de compraventa ciertas garantías o aclaraciones para no verse involucrados en tales litigios. This paper focuses on the analysis of the conflicts that revolved around the buying of slaves in northeast New Granada during the 18th century. Deferred legalization, unauthorized sales, pending payments, mortgaged slaves, confu-sion about the real state of the slave traded, were situations that triggered bitter disputes and lawsuits ended sometimes with the declaration of rescission, that is, the cancellation of the contract of sale and the return of the slave. Given this background, traders were careful to place certain warranties or clarifications into the deed of sale to avoid being involved in such litigation.

    Full Text Available El artículo estudia cómo resolvía el Estado español el abastecimiento de armas en los siglos XVII y XVIII según la fórmula empresarial utilizada: qué tipo de empresario y qué tipo de organización empresarial. Ello lleva, en primer lugar, a una somera, pero necesaria descripción del sector, en concreto, la fabricación de cañones, de municiones y de fusiles. Esta parte incluye consideraciones sobre la organización empresarial y sobre los aspectos técnicos. El cuerpo del trabajo estudia la figura de los asentistas en cada sector: quiénes eran, qué otros negocios tenían, cuáles eran las características de los asientos, cuál era su relación con la Administración, si desarrollaban vínculos familiares, etc. Hasta 1760 dominó el abastecimiento por asiento, pero tras esa fecha el Estado cambió, en unos cuantos casos, hacia otras fórmulas, para pasar a ser un Estado fabricante. La última parte del artículo estudia esta época, sus circunstancias y las consecuencias que trajo en la producción, en el abastecimiento y en los empresarios.

Sin embargo, a pesar del reconocimiento que los Ilustrados otorgaron al sexo femenino, siguieron relegando a éstas a las paredes del hogar, exhortándoles a quedarse fuera del mundo del trabajo extra-doméstico, reservado sólo para los hombres de la familia. No obstante, la necesidad obligaba, y cuando los recursos u hombres de una casa escaseaban, la mujer tenía que salir a buscarse el sustento. Este es el caso de cientos de mujeres del Principado de Asturias, dónde, a mediados del siglo XVIII, la realidad femenina difería de lo que lo que se consideraba ideal. Este trabajo arrojará pues luz, en un campo hasta ahora desconocido: el del mundo profesional de las mujeres asturianas del Setecientos, dónde comprobaremos cómo en ocasiones llegaban a adquirir, gracias a su status profesional, papeles relevantes dentro de la sociedad.

    Miller, C. J.

    The local environment of a Brightest Cluster Galaxy (BCG) can provide insight into the (still not understood) formation process of the BCG itself. BCGs are the most massive galaxies in the Universe, and their formation and evolution are a popular and current research topic (Linden et al. 2006, Bernardi et al. 2006, Lauer et al. 2006). They have been studied for some time (Sandage 1972, Ostriker & Tremaine 1975, White 1976, Thuan & Romanishin 1981, Merritt 1985, Postman and Lauer 1995, among many others). Our goal in this chapter is to study how the local environment can affect the physical and measurable properties of BCGs. We will conduct an exploratory research exercise. In this chapter, we will show how the Virtual Observatory (VO) can be effectively utilized for doing modern scientific research on BCGs. We identify the scientific functionalities we need, the datasets we require, and the service locations in order to discover and access those data. This chapter utilizes IDL's VOlib, which is described in Chapter 24 of this book and is available at http://www.nvo.noao.edu. IDL provides the capability to perform the entire range of astronomical scientific analyses in one environment: from image reduction and analysis to complex catalog manipulations, statistics, and publication quality figures. At the 2005 and 2006 NVO Summer Schools, user statistics show that IDL was the most commonly used programming language by the students (nearly 3-to-1 over languages like IRAF, Perl, and Python). In this chapter we show how the integration of IDL to the VO through VOlib provides even greater capabilities and possibilities for conducting science in the era of the Virtual Observatory. The reader should familiarize themselves with the VOlib libraries before attempting the examples in this tutorial. We first build a research plan. We then discover the service URLs we will need to access the data. We then apply the necessary functions and tools to these data before we can do our

    We analyze here the common features of two dynamical regimes: a quantum and a classical one. We deal with a well known semi-classic system in its route towards the classical limit, together with its purely classic counterpart. We wish to ascertain i) whether some quantum remnants can be found in the classical limit and ii) the details of the quantum-classic transition. The so-called mutual information is the appropriate quantifier for this task. Additionally, we study the Bandt–Pompe's symbolic patterns that characterize dynamical time series (representative of the semi-classical system under scrutiny) in their evolution towards the classical limit. - Highlights: • We investigate the classical limit (CL) of a well known semi classical model. • The study is made by reference to the Bandt Pompe symbolic approach. • The number and type of associated symbols changes as one proceeds towards the CL. • We ascertain which symbols pertaining to the quantum zone remain in the CL.

    Full Text Available The author discusses the relocation of Panamá City to its current site, as well as the morphological characteristics that made it both a fortress and a market place. In its new location, the city continued to play to role of the sea port and commercial center that it played before by being a key stop in the silver route and house of trade of the Americas; but the new city was surrounded by the wall, and built according to a plan that is the perfect example of the classic colonial city in Spanish America.

    Se analiza aquí el traslado de la ciudad de Panamá la Vieja a su actual emplazamiento y las características morfológicas que la convierten en una ciudad "fortaleza y mercado" a la vez, dado que sigue desempeñando la misma función portuaria y comercial que antaño: la de centro neurálgico del comercio americano y puerto de tránsito y transbordo en la ruta de la plata, sólo que ahora su perímetro urbano es ceñido por un gran cinturón abaluartado y su trazado reproduce con gran perfección el modelo clásico de la ciudad americana colonial.

    Full Text Available The purpose. The objective of this paper is to illustrate how the biological basis of the “natural” male and female characteristics is subjected to doubt in the books of the women-writers - “feminists before feminism” despite the dictatorship of the specific gender norms of the philosophical concepts of that period. These very concepts of the classical philosophy determined ideology, psychology and reasoning of both sexes in the Enlightenment including both public and private spheres. The “picture” of the sociocultural realia of that period is analyzed with the help of the gender which is used here not only as a role or feature but as methodology. The scientific novelty lies in constructing a more complete polyphonical picture of the sociocultural life in the epoch of the Enlightenment in rejecting the “one-sex” interpretation of the philosophy and culture of that period in assuring that there were two subjects in the Enlightenment history and culture-representatives of both sexes. The analysis of philosophical texts and fiction allows to make a conclusion: early feminists were sure that the rational capabilities of men and women do not differ the sexual differences are irrelevant in the problems of intellectual and moral education.

  15. Religious ecstasy in classical Sufism

    Directory of Open Access Journals (Sweden)

    Göran Ogén

    1982-01-01

    Full Text Available The purpose of this essay is to shed some light on the phenomenon of religious ecstasy as met within Islamic mysticism and there particularly during its classical period. In this case, the expression "classical Sufism" refers to the period of Sufi history from about 850 A.D. until circa 1100 A.D. In the Sufi vocabulary there is even a rather differentiated terminology concerning these ecstatic experiences or states; whether different descriptions of one and the same experience are involved or whether the terms actually describe different experiences is a question that we must set aside for the present. There are, however, Sufis expressing the opinion that these different states of mind are based on one single experience in spite of the difference in terms. A generic term for these experiences or states is not to be found in the Sufi terminology however, so the problem of which of these phenomena must be present in order for ecstasy to be evidenced—or which of them would be sufficient— does not therefore arise for the Sufis. So instead of speaking of religious ecstasy in general, they either refer to the single specific terms in question or else use the plural of one of the words employed to designate one of the terms we include in "religious ecstasy". They thus speak of "ecstasies", mawagid from the singular form wagd—if one should at all attempt a translation of this plural. This plural is a genuine Sufi construction and does not otherwise seem to occur in the Arabic language, except as a later borrowing. Psalmody based on the Koranic vocabulary remains the main procedure for putting oneself in ecstasy. If we add 'and listening to psalmody', we then obtain a fairly satisfactory picture of the external conditions for the Sufis' ecstasy until the eleventh century, when various innovations begin to appear. As far as the darwiš-dance is concerned, it is not until the thirteenth century with Rumi that it becomes transformed from an expression

    Any two infinite-dimensional (separable) Hilbert spaces are unitarily isomorphic. The sets of all their self-adjoint operators are also therefore unitarily equivalent. Thus if all self-adjoint operators can be observed, and if there is no further major axiom in quantum physics than those formulated for example in Dirac’s ‘quantum mechanics’, then a quantum physicist would not be able to tell a torus from a hole in the ground. We argue that there are indeed such axioms involving observables with smooth time evolution: they contain commutative subalgebras from which the spatial slice of spacetime with its topology (and with further refinements of the axiom, its - and ∞ - structures) can be reconstructed using Gel’fand–Naimark theory and its extensions. Classical topology is an attribute of only certain quantum observables for these axioms, the spatial slice emergent from quantum physics getting progressively less differentiable with increasingly higher excitations of energy and eventually altogether ceasing to exist. After formulating these axioms, we apply them to show the possibility of topology change and to discuss quantized fuzzy topologies. Fundamental issues concerning the role of time in quantum physics are also addressed.

    Maly, Joseph; Alinari, Lapo

    2016-09-01

    Pembrolizumab is a humanized monoclonal antibody directed against programmed cell death protein 1 (PD-1), a key immune-inhibitory molecule expressed on T cells and implicated in CD4+ T-cell exhaustion and tumor immune-escape mechanisms. Classical Hodgkin's lymphoma (cHL) is a unique B-cell malignancy in the sense that malignant Reed-Sternberg (RS) cells represent a small percentage of cells within an extensive immune cell infiltrate. PD-1 ligands are upregulated on RS cells as a consequence of both chromosome 9p24.1 amplification and Epstein-Barr virus infection and by interacting with PD-1 promote an immune-suppressive effect. By augmenting antitumor immune response, pembrolizumab and nivolumab, another monoclonal antibody against PD-1, have shown significant activity in patients with relapsed/refractory cHL as well as an acceptable toxicity profile with immune-related adverse events that are generally manageable. In this review, we explore the rationale for targeting PD-1 in cHL, review the clinical trial results supporting the use of checkpoint inhibitors in this disease, and present future directions for investigation in which this approach may be used.

    2011-06-01

    It is an old result of Bohr that, according to classical statistical mechanics, at equilibrium a system of electrons in a static magnetic field presents no magnetization. Thus a magnetization can occur only in an out of equilibrium state, such as that produced through the Foucault currents when a magnetic field is switched on. It was suggested by Bohr that, after the establishment of such a nonequilibrium state, the system of electrons would quickly relax back to equilibrium. In the present paper, we study numerically the relaxation to equilibrium in a modified Bohr model, which is mathematically equivalent to a billiard with obstacles, immersed in a magnetic field that is adiabatically switched on. We show that it is not guaranteed that equilibrium is attained within the typical time scales of microscopic dynamics. Depending on the values of the parameters, one has a relaxation either to equilibrium or to a diamagnetic (presumably metastable) state. The analogy with the relaxation properties in the Fermi Pasta Ulam problem is also pointed out.

    Full Text Available Aim of this article - to analyze Hegel and Karl Marx’s classic bureaucracy theories and also Max Weber’s concept of rational bureaucracy and its development in the works of Herbert Simon, Robert Merton, Peter Blau and Michel Crozier. It shows that the above listed researchers only undertook a change of terminology within the same theoretical tradition. The article describes different approaches to the bureaucratic system of administrative schools of the late 1950s and early 1980s. Major conclusions in the article include the following: administering the state apparatus consists in the organization of government on the basis of regulated rights, mandatory procedures that are invoked to ensure balance in the interest of man and society; bad effectiveness of government, infringement of the rights and freedoms of the individual is the result of dysfunction in the state apparatus; the struggle against it can be carried out with the help of administrative, economical and legal methods.DOI: http://dx.doi.org/10.12731/2218-7405-2013-6-45

    Full Text Available Cada país tiene sus casos historiográficos y Portugal no escapa a la regla. Tenemos muchos casos, muchas dudas, muchas historias. El dia 3 de septiembre de 1758 quedará para siempre envuelto en el misterio, lo que no impide que procuremos hacer la mayor luz posible sobre el tema del atentado contra el rey D. José, junto a la quinta de Belém. El atentado originó un proceso sumarísimo que en casi cuatro meses liquidó las Casas de Távora, Atouguia y Aveiro, así como a la Compañía de Jesús, con las monstruosas ejecuciones en el patíbulo de Belém del 13 de enero de 1759. Los inventarios y el secuestro de bienes ejecutados por orden de la Junta da Inconfidência, pueden servir tanto para medir la grandeza de las Casas, como también su situación social y financiera. Por estos inventarios se evidencia que estas Casas, que eran socialmente de las más consideradas en Portugal en el siglo XVIII, estaban bastante endeudadas. A mediados del siglo XVIII, la clase emergente de hombres de negocios y de prestamistas era, de hecho, la poseedora de los grandes activos de éstos y de otros Grandes de Portugal ya que los mismos servían de garantía a los créditos concedidos. Sin embargo, la aristocracia, profundamente endogámica, no se permitía ninguna contaminación con las clases adineradas, pero sin título.

  1. Structure of classical affine and classical affine fractional W-algebras

    We introduce a classical BRST complex (See Definition 3.2.) and show that one can construct a classical affine W-algebra via the complex. This definition clarifies that classical affine W-algebras can be considered as quasi-classical limits of quantum affine W-algebras. We also give a definition of a classical affine fractional W-algebra as a Poisson vertex algebra. As in the classical affine case, a classical affine fractional W-algebra has two compatible λ-brackets and is isomorphic to an algebra of differential polynomials as a differential algebra. When a classical affine fractional W-algebra is associated to a minimal nilpotent, we describe explicit forms of free generators and compute λ-brackets between them. Provided some assumptions on a classical affine fractional W-algebra, we find an infinite sequence of integrable systems related to the algebra, using the generalized Drinfel’d and Sokolov reduction.

    2009-04-01

    Lichens growing on skulls were known in late medieval times as usnea or moss of a dead man's skull and were recommended as highly beneficial in various diseases. They were, in addition, the main ingredient of Unguentum armariun, a liniment used in a curious medical practice: the magnetic cure of wounds. We can place this chapter of the history of phytotherapy within the wider cultural context of the period, which saw the definition of nature become increasingly more fluid and open to a variety of novel interpretations.

  4. Locking classical correlation in quantum states

    We show that there exist bipartite quantum states which contain large hidden classical correlation that can be unlocked by a disproportionately small amount of classical communication. In particular, there are $(2n+1)$-qubit states for which a one bit message doubles the optimal classical mutual information between measurement results on the subsystems, from $n/2$ bits to $n$ bits. States exhibiting this behavior need not be entangled. We study the range of states exhibiting this phenomenon and bound its magnitude.

    Classical communication through quantum channels may be enhanced by sharing entanglement. Superdense coding allows the encoding, and transmission, of up to two classical bits of information in a single qubit. In this paper, the maximum classical channel capacity for states that are not maximally entangled is derived. Particular schemes are then shown to attain this capacity, firstly for pairs of qubits, and secondly for pairs of qutrits.

  6. Chapter 9: understanding the nervous system in the 18th century.

    Science.gov (United States)

    Smith, Christopher U M

    2010-01-01

    The 18th century was an age of transition. The time-honored neuropsychology of classical and medieval times, mechanized in Descartes' hydraulic neurophysiology, was undermined by microscopical observations and careful physiological experimentation. Yet it was not until the very end of the century, when work on electric fish and amphibia began to suggest an acceptable successor to "animal spirit," that the old understanding of human neurophysiology began to fade. This chapter traces this slow retreat from the iatrophysics of the early part of the century, with its hollow nerves and animal spirits, through a number of stop-gap explanations involving mysterious subtle fluids or forces described variously as irritability, élan vital, vis viva, vis insita, the spirit of animation etc., or perhaps involving vibrations and vibratiuncles and mysterious magnetic effluvia, to the dawning electrophysiology of the end of the century and the beginning of the next. This developing understanding filtered slowly through to affect medical education, and the 18th century saw the development of strong medical schools at Leiden, Edinburgh, Paris, Bologna and London. Associated with these developments there was a great increase, as a well-known physician looking back at the beginning of the following century noted, in a class of diseases that had little concerned physicians in the preceding century - "nervous disorders."

    2012-01-01

    After a general description of the tomographic picture for classical systems, a tomographic description of free classical scalar fields is proposed both in a finite cavity and the continuum. The tomographic description is constructed in analogy with the classical tomographic picture of an ensemble of harmonic oscillators. The tomograms of a number of relevant states such as the canonical distribution, the classical counterpart of quantum coherent states and a new family of so called Gauss--Laguerre states, are discussed. Finally the Liouville equation for field states is described in the tomographic picture offering an alternative description of the dynamics of the system that can be extended naturally to other fields.

  8. Classical Fields and the Quantum Concept

    CERN Document Server

    De Souza, M M

    1996-01-01

    We do a critical review of the Faraday-Maxwell concept of classical field and of its quantization process. With the hindsight knowledge of the essentially quantum character of the interactions, we use a naive classical model of field, based on exchange of classical massless particles, for a comparative and qualitative analysis of the physical content of the Coulomb's and Gauss's laws. It enlightens the physical meaning of a field singularity and of a static field. One can understand the problems on quantizing a classical field but not the hope of quantizing the gravitational field right from General Relativity.

  9. Seven Steps Towards the Classical World

    2001-01-01

    Classical physics is about real objects, like apples falling from trees, whose motion is governed by Newtonian laws. In standard Quantum Mechanics only the wave function or the results of measurements exist, and to answer the question of how the classical world can be part of the quantum world is a rather formidable task. However, this is not the case for Bohmian mechanics, which, like classical mechanics, is a theory about real objects. In Bohmian terms, the problem of the classical limit becomes very simple: when do the Bohmian trajectories look Newtonian?

  10. Limitations on Cloning in Classical Mechanics

    OpenAIRE

    Fenyes, Aaron

    2010-01-01

    In this paper, we show that a result precisely analogous to the traditional quantum no-cloning theorem holds in classical mechanics. This classical no-cloning theorem does not prohibit classical cloning, we argue, because it is based on a too-restrictive definition of cloning. Using a less popular, more inclusive definition of cloning, we give examples of classical cloning processes. We also prove that a cloning machine must be at least as complicated as the object it is supposed to clone.

    1986-01-01

    The wavelengths of inner-shell 1s-2p transitions in the ions Fe XVIII-XXIV have been measured in solar flare spectra recorded by the Naval Research Laboratory crystal spectrometer (SOLFLEX) on the Air Force P78-1 spacecraft. The measurements are compared with previous measurements and with recently calculated wavelengths. It is found that the measured wavelengths are systematically larger than the wavelengths calculated using the Z-expansion method by up to 0.65 mA. For the more highly charged ions, these differences can be attributed to the QED contributions to the transition energies that are not included in the Z-expansion calculations.

During the second half of the XVIII century and under the government of the Borbones, the politics established seemed to accompany the increase and growth of the cities and the towns in Spanish America, and to incentivate the urbanization of the areas of frontier of their Empire. Two queries articulate this work. Can the proposals formulated by the colonial authorities for Buenos Aires be located inside the urbanization politics proposed by the Borbones for frontier areas in Spanish America ? If this was this way, what concretion level has this politics had during the last decades of colonial bond? The establishment of towns will be studied for the case of Buenos Aires during the last decades of the XVIII century.Aunque el desarrollo urbano en América no fue privativo de la colonización europea, la fundación de pueblos y ciudades constituyó una política específica de conquista y dominación colonial.

Si esto fue así, ¿qué nivel de concreción ha tenido dicha política durante las últimas décadas de vínculo colonial?

    2004-06-01

    Full Text Available Los procesos inquisitoriales a beatas por ilusas y alumbradas en la Nueva España, durante el siglo XVIII, muestran cómo la "anormalidad" del modelo de espiritualidad místico y ascético, al que las mujeres fueron tan proclives en dicha centuria, pasó al campo del discurso médico. La mirada masculina se desconcierta con la continuidad de los signos exteriores de la espiritualidad femenina, son sus cuerpos el medio por el cual dan cuenta de que algo fuera de lo normal las identifica: arrobamientos, posesiones, ataques, temblores y mal de corazón, entre otros. En las beatas, estos fenómenos desconciertan y son considerados más sospechosos, por cuanto ellas suelen ser mujeres pobres y simples -al decir de los religiosos- que viven de forma indenpendiente y hacen de la vida religiosa una forma de subsistencia. Este trabajo muestra cómo los inquisidores se suman a la lógica racionalista del siglo institucionalizando la asociación entre fenómenos místicos, locura e histeria en las mujeres. El cuerpo femenino, su extrañeza y la incomodidad que provoca en toda sociedad, permite en la sociedad occidental y en el espacio colonial realizar los primeros usos legales de la histeria como devaluación del verbo y la acción de las mujeres en el gran relato de la historiaThe inquisitorial trials of pious women on the charges of being deluded and spellbound in the New Spain, during the XVIII century, show how the ""abnormality" of the mistic and ascetic model of spirituality to which women were so fond of in said century moved in to the realm of the medical discourse. The male look is bewildered by the continuity of the external signs of female sprirituality, their bodies are the means through which they account for something out the normalcy that identifies them: raptures, possessions, fits, shudders, and melancholy, among others. In the pious women, these phenomena puzzle the mind and are suspiciously considered in that they used to be poor and

In an altar table, presently covered with modern white paint, were found some layers of ancient paintings from different periods, and identified by the pigments used in each one. The analysis of 15 sculptures - dating from XVII and XVIII centuries - revealed the original pigments, the elemental composition of the clay and materials employed in recent restorations. In most of the cases the original gilding had been covered with commercial golden paint. The analysis of 14 wood panels (XVIII century), at the vault and side walls of the chapel - representing nine episodes of the saint's life - revealed original pigments and retouching regions. The original pigments used in the paintings were: lead white, vermilion, ochre (red, yellow and brown), umber, bone black, green earth, verdigris and Prussian blue. In some regions of retouching were identified: chromium yellow, viridian/chromium oxide and zinc white. (author)

  1. Usos y acepciones de chino, china en el norte del Perú, siglos XVIII-XIX

    Full Text Available ResumenSe estudian los usos de la palabra chino, china en el norte peruano, entre los siglos XVIII y XIX, a partir de documentos históricos y coplas de la lírica popular. En contra de propuestas anteriores, se confirma el uso efectivo del término, sobre todo en su forma femenina, y se postulan dos acepciones: la primera, vinculada a la terminología de castas, alude a un tipo de mestizaje que une los troncos indio y africano, con un componente menor, variable, de “sangre blanca”, mientras que la segunda hace referencia a una mujer joven, generalmente campesina. Se estudia también el uso de la palabra como una fórmula de apelación a la amada en la lírica popular y se concluye que, aunque probablemente esta fórmula se derivó de la terminología racial, la palabra rápidamente adquirió matices afectivos positivos, con lo cual permitió aludir a la mujer cercana, aquella que era posible cortejar. Se sugiere que la antigua acepción ‘criada’, central en las fuentes coloniales del XVI y el XVII, se empezó a desdibujar en el período estudiado y, en línea con trabajos previos, se postula una competencia entre este lexema y la palabra homófona referida a las migrantes asiáticas desde fines del XIX.Palabras clave: categorización racial de seres humanos, lexicología, norte del Perú, siglos XVIII y XIXAbstractThis paper studies the uses of the word chino, china in northern Peru in the eighteenth and nineteenth centuries, via historical documents and popular poetry couplets. Contrary to previous proposals, we corroborate the actual use of this term, especially in its feminine form, and we propose two possible meanings for it: the first, linked to caste terminology, refers to a type of “racial mix” between “Indian” and “African”, with a minor and variable component of “white blood”, while the second refers to a young woman, usually a peasant. We also examine the use of the word as a formulaic

    The chapter provides an itinerary of knowledge on nervous system anatomy as one of the pillars of clinical neurology. The journey starts from the Renaissance explosion on the approach to the human body, its functions and its diseases, dealing with the seminal contributions of Leonardo da Vinci and Vesalius. The itinerary proceeds through the contributions of the 17th century, especially by Thomas Willis and the pioneering investigations of Marcello Malpighi and Antony van Leeuwenhoek, and onto the 18th century. The itinerary thus leads to the progress from gross anatomy to the microscopic investigation of the nervous system in the 19th century: the reticular theories, the revolution of the neural doctrine and their protagonists (Camillo Golgi and Santiago Ramón y Cajal), which initiated the modern era of the neurosciences. The chapter also includes sections on the contributions of developmental neuroanatomy to neurology, on the history of tract tracing, and on the cytoarchitecture of the cerebral cortex. The never-ending story of the anatomical foundations of clinical neurology continues to evolve at the dawn of the 21st century, including knowledge that guides deep brain stimulation, and novel approaches to the anatomy of the living brain based on rapidly developing neuroimaging technology.

    Full Text Available ¿Como eran enfrentados los desastres naturales en los siglos XVIII y XIX, cuando no existían los mecanismos institucionales que hoy conocemos bajo el moderno concepto de la 'prevención de desastres', con todo su sistema de ayudas tecnológicas, médicas e institucionales? Los desastres se asemejan a las enfermedades, al ser un elemento de desorganización social y un factor de temido desarreglo para la vida cotidiana, por lo que permiten hacer visibles las articulaciones internas de una sociedad y las tensiones que la atraviesan. Son un punto privilegiado para percibir el significado de mecanismos administrativos y prácticas religiosas en torno a fenómenos que vulneran una comunidad, así como la imagen que una sociedad tiene de sí misma. A pesar de que los archivos coloniales y republicanos poseen información dispersa sobre el tema, es posible identificar la manera como se sucedían con recurrencia fuertes temporadas de invierno que obstaculizaban el comercio y la movilización de personas y mercancías. Los documentos históricos también permiten conocer la ocurrencia de tempestades, granizadas, inundaciones, largas temporadas de sequía, vendavales, erupciones volcánicas, terremotos y deslizamientos de tierra y lodo. que podían arrasar cultivos, animales del campo y poblaciones enteras. Al hecho de que sucedieran estos eventos, contribuían las acciones humanas de intervención sobre los paisajes naturales.

However, we find very few images that show hermit activities with different habits and from different places. Thus the importance of the XVIIIth century picture subject of this paper, that depicts religious forms associated to cave life which had a long tradition on the site of La Luz in Murcia. We study the locus amoenus which is symbolic but inspired on a real environment of hermit inhabited caves, whose practices were regulated by the prelate of the Diocese of Cartagena, as proven by an inscription and by historic records. We look at the uniqueness of the picture and relate it to historic and literary sources on the subject.Las representaciones pictóricas de Tebaidas fueron comunes en la Edad Moderna. Sin embargo, apenas se conocen imágenes que muestren actividad eremítica con monjes de diversa procedencia y con distintos hábitos. De ahí la importancia del cuadro analizado del siglo XVIII, que plasma formas de religiosidad, vinculadas a la vida rupestre, de larga tradición en el paraje mostrado de La Luz en Murcia. Se estudia el locus amoenus pintado, que se inspira en un lugar simbólico y en un entorno real, con las cuevas que habitaron anacoretas, cuyas prácticas fueron reglamentadas por el prelado de la Diócesis de Cartagena, como prueban una inscripción y datos de archivo. Se aborda la singularidad del lienzo, relacionándolo con fuentes documentales y literarias alusivas al tema.

Dans cette province-ci, les contacts avec le mouvement d'idées européen ont été plus puissants. La lutte d'affirmation nationale a mené à l'augmentation de la conscience politique de la société moldave et à une participation plus accentuée à la vie politique.

    Full Text Available Este trabajo aborda la relación entre honor y prácticas sociales en el siglo XVIII chileno, analizando la figura de los duelos o expresiones de violencia masculina formalizada. Junto con indagar en los mecanismos restitutorios del honor y su vinculación a los fundamentos de una masculinidad tradicional, reflexiona sobre las gamas de manejo social de dicho valor en el período señalado. Teóricamente se rescatan los aportes de la antropología y se hace un balance del tratamiento historiográfico del problema. Desde los registros judiciales se plantea el carácter transversal del honor en términos sociales y se aborda su "doble naturaleza" en cuanto espacio relacional y ámbito de confrontación de los individuos.This works deals with the relationship between honor and social practices in Chile's eighteenth century and analyzes formal duels or expressions of legalized masculine violence. This article explores various manifestations of the social ways used to deal with honor at that time, together with the inquiries about mechanisms used to restore honor and its links with traditional masculinity. Theoretically, this work rescues contributions made by anthropologists and provides an overview of how honor and masculinity have been examined in the historiography. Starting from judicial records, the article considers the transversal character of honor in social terms and approaches its "double significance" as both a relational space for people and as a sphere for the confrontation of individuals.

    Full Text Available O presente artigo estuda o contrabando no século XVIII, em especial em relação ao Rio de Janeiro e ao Atlântico Sul. Neste artigo discuto não apenas a mecânica do contrabando e os participantes deste comércio ilegal, mas os vários fatores que ocasionaram as medidas portuguesas, metropolitanas e coloniais para impedir o comércio clandestino. Estudo particularmente como tais medidas representaram um compromisso entre diferentes interesses, tais como: o papel do monarca, a integridade ou a maleabilidade da autoridade real, a aplicação dessa legislação e os tipos de penalidades impostas aos infratores, trazendo questões sobre o que constituíam ações legais ou ilegais, assim como questões mais amplas relativas à ética e à moralidade pública no Brasil colônia.This article focuses on contraband in the eighteenth century, with special reference to Rio de Janeiro and the South Atlantic. It discusses not merely the mechanics of contraband and the participants in this illegal trade, but the many factors that contributed to Portuguese metropolitan and colonial measures to curb clandestine trade. I am particularly intrigued by the degree to which such measures represented a compromise between different interests. The role of the monarch, the integrity or malleability of royal authority, the latitude in enforcement of such legislation and the range of penalties imposed on infractors raise questions as to what constituted legal or illegal actions, as well as broader issues of ethics and public morality in colonial Brazil.

    Full Text Available RESUMEN: La crueldad o barbarie ibérica alimenta la Leyenda Negra antihispánica desde el siglo XVI. En el siglo XVIII, Siglo de las Luces, los viajeros franceses llegan a España con la idea de que los españoles son seres violentos, bárbaros y crueles e intentan demostrarlo, basándose en el examen de tres aspectos de la sociedad española: las corridas de toros, el tribunal de la Inquisición y los crímenes con navaja. No obstante, las reacciones no serán unánimes como se podía pensar: unos seguirán condenando a los crueles ibéricos, otros adoptarán una actitud más moderada, intentando analizar la situación con objetividad y sentido crítico.ABSTRACT: Iberian cruelty or barbarity has been fueling the anti-hispanic Black Legend since the 16th century. In the 18th century, the Age of the Enlightenment, French travellers arrived in Spain bearing in mind that the Spaniards were violent, barbarian and cruel beings and they attempted to demostrate that this was so by taking a close look at three aspects of Spanish society: bullfighting, the Inquisition and bloody murders. However, the reactions were not as identical as one might think: some relentlessly condemned the cruel Spaniards, while others adopted a more moderate attitude, trying to analyse the situation objectively and critically.

    Full Text Available This article analyses an unpublished text written by a nun in Santiago of Chile around the mid-eighteenth century. The text, written by her confessor’s command, recounts the visions and locutions that she had with the Virgin Mary, which revolved around the figure of the confessor. This makes quite a special report because the priest appears as a central character of the visions, and the one who benefits from the intercession of the nun before the heavenly beings. At the same time, the account gives evidence of the nun’s awareness of her role, her limitations as a woman and her mediator power. On the other hand, the nun’s narrative shows not only the way of living her faith, but also allows us to get nearer to the ‘religious mentality’ of her time.El artículo analiza un texto inédito escrito por una monja de Santiago de Chile, a mediados del siglo XVIII, por mandato de su confesor. En él se refieren las visiones y locuciones tuvo con la Virgen, las que giran en torno a la figura del confesor. Esto hace bastante especial el relato, pues el sacerdote aparece como un personaje central de las visiones, que se beneficia de la intercesión de la religiosa ante los seres celestiales. Pero al mismo tiempo, la narración deja en evidencia a una religiosa muy consciente de su papel, de sus limitaciones como mujer y de su poder mediador. Por otra parte, el relato de la monja muestra no sólo su manera de vivir la fe, sino también nos permite acercarnos a la mentalidad religiosa de su época.

    Tunneling in the unimolecular reactions H/sub 2/C/sub 2/ ..-->.. HC/sub 2/H, HNC ..-->.. HCN, and H/sub 2/CO ..-->.. H/sub 2/ + CO is studied with a classical Hamiltonian that allows the reaction coordinate and transverse vibrational modes to be considered directly. A combination of classical perturbation theory and the semiclassical WKB method allows tunneling probabilities to be obtained, and a statistical theory (RRKM) is used to construct rate constants for these reactions in the tunneling regime. In this fashion, it is found that tunneling may be important, particularly for low excitation energies. Nonadiabatic charge transfer in the reaction Na + I ..-->.. Na /sup +/ + I/sup -/ is treated with classical trajectories based on a classical Hamiltonian that is the analogue of a quantum matrix representation. The charge transfer cross section obtained is found to agree reasonably well with the exact quantum results. An approximate semiclassical formula, valid at high energies, is also obtained. The interaction of radiation and matter is treated from a classical viewpoint. The excitation of an HF molecule in a strong laser is described with classical trajectories. Quantum mechanical results are also obtained and compared to the classical results. Although the detailed structure of the pulse time averaged energy absorption cannot be reproduced classically, classical mechanics does predict the correct magnitude of energy absorption, as well as certain other qualitative features. The classical behavior of a nonrotating diatomic molecule in a strong laser field is considered further, by generating a period advance map that allows the solution over many periods of oscillation of the laser to be obtained with relative ease. Classical states are found to form beautiful spirals in phase space as time progresses. A simple pendulum model is found to describe the major qualitative features. (WHM)

    The International Association for Mathematical Geosciences (IAMG) Student Chapter Freiberg was founded in 2007 at the Technische Universität Bergakademie Freiberg (TUBAF) in Germany by national and international graduate and undergraduate students of various geoscientific as well as natural science disciplines. The major aim of the IAMG is to promote international cooperation in the application and use of Mathematics in Geosciences research and technology. The IAMG encourages all types of students and young scientists to found and maintain student chapters, which can even receive limited financial support by the IAMG. Following this encouragement, generations of students at TUBAF have build up and established a prosperous range of activities. These might be an example and an invitation for other young scientists and institutions worldwide to run similar activities. We, some of the current and former students behind the student chapter, have organised talks, membership drives, student seminars, guest lectures, several short courses and even international workshops. Some notable short courses were held by invited IAMG distinguished lecturers. The topics included "Statistical analysis in the Earth Sciences using R - a language and environment for statistical computing and graphics", "Geomathematical Natural Resource Modeling" and "Introduction to Geostatistics for Environmental Applications and Natural Resources Evaluation: Basic Concepts and Examples". Furthermore, we conducted short courses by ourselves. Here, the topics included basic introductions into MATLAB, object oriented programming concepts for geoscientists using MATLAB and an introduction to the Keyhole Markup Language (KML). Most of those short courses lasted several days and provided an excellent and unprecedented teaching experience for us. We were given credit by attending students for filling gaps in our university's curriculum by providing in-depth and hands-on tutorials on topics, which were merely
