Chaotic behavior in the Henon mapping
Energy Technology Data Exchange (ETDEWEB)
Marotto, F R [Drexel Univ., Philadelphia, PA (USA). Dept. of Mathematics
1979-01-01
In a previous work Henon investigated a two-dimensional difference equation which was motivated by a hydrodynamical system of Lorenz. Numerically solving this equation indicated for certain parameter values the existence of a 'strange attractor', i.e., a region in the plane which attracts bounded solutions and in which solutions wander erratically. In the present work it is shown that this behavior is related to the mathematical concept of 'chaos'. Using general methods previously developed, it is proven analytically that for some parameter values the mapping has a transversal homoclinic orbit, which implies the existence of the chaotic behavior observed by Henon.

Michel joined CERN early 1979. He started his career in the “Experimental Physics” Division "BCDMS (N4) Muon experiment" and later continued with software support to the GEM project with Emilio Pagiola. He joined the IT Department in 2005 and participated in the implementation of the digital version of PrintShop. Michel is one of the world experts in TeX and LaTex (programming languages for text layout) and is the author of several books on the subject. But at CERN, it is foremost through the Staff Association that we know Michel who successively served as Vice President, secretary and member of the Executive Committee, and since January 2011 and until December 2015, as President of the Staff Association. Do not forget that Michel has consistently been proactive with new proposals and is the initiator of social advances such as SLS (Saved Leaved Scheme) or PRP (Progressive Retirement Programme). At the end of his mandate, Michel expressed his pride fo...

An extended Henon-Heiles system
International Nuclear Information System (INIS)
Hone, A.N.W.; Novikov, V.; Verhoeven, C.
2008-01-01
We consider an integrable system of partial differential equations possessing a Lax pair with an energy-dependent Lax operator of second order, of the type described by Antonowicz and Fordy. By taking the travelling wave reduction of this system we show that the integrable case (ii) Henon-Heiles system can be extended by adding an arbitrary number of non-polynomial (rational) terms to the potential
Dynamics of unidirectionally coupled bistable Henon maps
International Nuclear Information System (INIS)
Sausedo-Solorio, J.M.; Pisarchik, A.N.
2011-01-01
We study dynamics of two bistable Henon maps coupled in a master-slave configuration. In the case of coexistence of two periodic orbits, the slave map evolves into the master map state after transients, which duration determines synchronization time and obeys a -1/2 power law with respect to the coupling strength. This scaling law is almost independent of the map parameter. In the case of coexistence of chaotic and periodic attractors, very complex dynamics is observed, including the emergence of new attractors as the coupling strength is increased. The attractor of the master map always exists in the slave map independently of the coupling strength. For a high coupling strength, complete synchronization can be achieved only for the attractor similar to that of the master map. -- Highlights: → We study dynamics of two bistable Henon maps coupled in a master-slave configuration. → Synchronization time for periodic orbits obeys a -1/2 power law with respect to coupling. → For a high coupling strength, the slave map remains bistable. → Complete synchronization can be achieved only when both maps stay at the same attractor.

In this paper, an adaptive fuzzy control method is presented to synchronize model-unknown discrete-time generalized Henon map. The proposed method is robust to approximate errors and disturbances, because it integrates the merits of adaptive fuzzy and the variable structure control. Moreover, it can realize the synchronizations of non-identical chaotic systems. The simulation results of synchronization of generalized Henon map show that it not only can synchronize model-unknown generalized Henon map but also is robust against the noise of the systems. These merits are advantageous for engineering realization.

2005-01-01
In this Letter, a generalized, systematic and automatic backstepping scheme is developed to investigate the Q-S synchronization of two identical 3a discrete-time dynamical systems and two different 3D discrete-time dynamical systems. With the aid of symbolic-numeric computation, we use the proposed scheme to illustrate chaos synchronization between two identical 3D generalized Henon map and Q-S synchronization between two different 3D generalized Henon map and Henon-like map via a scalar controller, respectively. Moreover numerical simulations are used to verify the effectiveness of the proposed scheme. In addition, the scheme can be also applied to investigate the tracking problem in the discrete-time systems and to generate automatically the scalar controller in computer with the aid of symbolic-numeric computation
What are mathematicians doing?
Friedman, B
1966-10-21
Let me emphasize the point I have been trying to make. The mathematician's playing with the roots of equations, a play which had no practical motivations and almost no possibilities of practical application, led to the recognition of the importance of symmetry and groups. The study of theory of groups led to mathematical discoveries in geometry and differential equations, and finally to prediction of the existence of a new elementary particle. Surely a surprising outcome for the ivory-tower speculations of an impractical mathematician! Despite my professional bias, I must acknowledge that the importance of symmetry was recognized before mathematicians invented the theory of groups. In 1794 William Blake wrote: Tiger, Tiger, burning bright In the forests of the night, What immortal hand or eye Could frame thy fearful symmetry? However, to the mathematicians must be given the credit of recognizing that, to understand symmetry, you must study the theory of groups. I can now answer my original question, What are mathematicians doing? They are trying to make precise the intuitions of poets.

When I was asked to give a talk here, being just a mathematician among the distinguished array of physicists invited to speak, I had great hesitation. Then it occurred to me, if Viki Weisskopf can conduct a symphony orchestra, maybe I can talk about physics. I felt consoled until yesterday evening when I discovered that he is a professional, and so I feel very, hesitant again. My title, "Physics for Mathematicians", will almost mean physics without mathematics. My interest is really to paraphrase a famous statement, not what mathematics can do for physics, but what physics can do for mathematics. That is the underlying motive...

This paper proposes a backstepping method to resolve the synchronization of discrete-time chaotic systems. The proposed scheme offers systematic design method for the synchronization of a class of discrete-time hyper-chaotic systems, which implies much complicated high-order chaotic systems can be used to improve the security in chaos communications. A well-known chaotic systems: generalized Henon map is considered as illustrative example to demonstrate the general applicability of backstepping design. Numerical simulations verify the effectiveness of the approach
Supersymmetry for mathematicians
Varadarajan, V S
2004-01-01
Supersymmetry has been the object of study by theoretical physicists since the early 1970's. In recent years it has attracted the interest of mathematicians because of its novelty, and because of significance, both in mathematics and physics, of the main issues it raises. This book presents the foundations of supersymmetry to the mathematically minded reader in a cogent and self-contained manner. It begins with a brief introduction to the physical foundations of the theory, especially the classification of relativistic particles and their wave equations, such as the equations of Dirac and Weyl

Topological and metric properties of Henon-type strange attractors
International Nuclear Information System (INIS)
Cvitanovic, P.; Gunaratne, G.H.; Procaccia, I.
1988-01-01
We use the set of all periodic points of Henon-type mappings to develop a theory of the topological and metric properties of their attractors. The topology of a Henon-type attractor is conveniently represented by a two-dimensional symbol plane, with the allowed and disallowed orbits cleanly separated by the ''pruning front.'' The pruning front is a function discontinuous on every binary rational number, but for maps with finite dissipation chemical bondbchemical bond<1, it is well approximated by a few steps, or, in the symbolic dynamics language, by a finite grammar. Thus equipped with the complete list of allowed periodic points, we reconstruct (to resolution of order b/sup n/) the physical attractor by piecing together the linearized neighborhoods of all periodic points of cycle length n. We use this representation to compute the singularity spectrum f(α). The description in terms of periodic points works very well in the ''hyperbolic phase,'' for α larger than some α/sub c/, where α/sub c/ is the value of α corresponding to the (conjectured) phase transition

Full Text Available The writers whose real vocation was not music left significant traces in the history of Serbian music critics and essayism of the late 19th century and the first half of the 20th century. Numerous authors, literary historians theoreticians and critics, jurists and theatre historians, wrote successfully on music in Serbian daily newspapers, literary and other magazines, until the Second World War. This study is devoted to Gustav Michel (1868 - 1926, one of the music amateurs who ought to be remembered in the history of Serbian music critics. Gustav Michel was a pharmacist by vocation. He ran a private pharmacy in Belgrade all his life. But he was a musician as well. He played the viola in the second (in chronological order of foundation Serbian String Quartet. The ensemble mostly consisted of amateurs, and it performed standard pieces of chamber music (W. A. Mozart L. v. Beethoven, F. Schubert, F. Mendelsohn-Bartholdy, A. Dvořžak. These musicians had performed public concerts in Belgrade since 1900 up until Michel’s death. Belgrade music critics prised the performances of this string ensemble highly. Gustav Michel was also a music critic. Until now only seven articles, published by this author between 1894 and 1903, in Order (Red, Folk Newspaper (Narodne novine and Serbian Literary Magazine (Srpski književni glasnik have been found. Michel’s preserved articles unambiguously prove that their author had a solid knowledge of music theory and history, the knowledge that exceeded amateurism. Nevertheless, Michel did not burden his first critics with expert language of musicology. Later on, in Serbian Literary Magazine, the magazine which left enough room for music, Michel penetrated more into musical terminology, thus educating slowly forming Serbian concert-going public. The analysis of Michel’s texts showed that he was not, in contrast to the majority of professional music critics, an opponent of virtuosity. Gentle and liberal, he did not
Strange attractor of Henon map and its basin

In this paper, Henon map is considered. For a positive measure set of parameters (a, b), we construct a trapping region G of topologically transitive strange attractor Aa,b for Ta,b, and prove that Aa,b= ∩n≥0Ta,bnG, and the basin B(Aa,b) of Aa,b is exactly the union of domain whose boundary is contained in w5(p) ∪wu(p) and ws(p). Therefore, that the conjecture posed by Benedicks and Carleson about the basin of strange attactor is true is proved. Furthermore, B(Aa,b) is simply connected and path-connected, w4(p2) is contained in the attainable boundary set of B(Aa,b) (where p2 is another hyperbolic fixed point of Ta,b).
Synchronization of generalized Henon map using polynomial controller
International Nuclear Information System (INIS)
Lam, H.K.
2010-01-01
This Letter presents the chaos synchronization of two discrete-time generalized Henon map, namely the drive and response systems. A polynomial controller is proposed to drive the system states of the response system to follow those of the drive system. The system stability of the error system formed by the drive and response systems and the synthesis of the polynomial controller are investigated using the sum-of-squares (SOS) technique. Based on the Lyapunov stability theory, stability conditions in terms of SOS are derived to guarantee the system stability and facilitate the controller synthesis. By satisfying the SOS-based stability conditions, chaotic synchronization is achieved. The solution of the SOS-based stability conditions can be found numerically using the third-party Matlab toolbox SOSTOOLS. A simulation example is given to illustrate the merits of the proposed polynomial control approach.

Full Text Available This paper investigates the synchronization of Yin and Yang chaotic T-S fuzzy Henon maps via PDC controllers. Based on the Chinese philosophy, Yin is the decreasing, negative, historical, or feminine principle in nature, while Yang is the increasing, positive, contemporary, or masculine principle in nature. Yin and Yang are two fundamental opposites in Chinese philosophy. The Henon map is an invertible map; so the Henon maps with increasing and decreasing argument can be called the Yang and Yin Henon maps, respectively. Chaos synchronization of Yin and Yang T-S fuzzy Henon maps is achieved by PDC controllers. The design of PDC controllers is based on the linear invertible matrix theory. The T-S fuzzy model of Yin and Yang Henon maps and the design of PDC controllers are novel, and the simulation results show that the approach is effective.
Mathematicians, Attributional Complexity, and Gender
Stalder, Daniel R.
Given indirect indications in sex role and soda! psychology research that mathematical-deductive reasoning may negatively relate to social acuity, Study 1 investigated whether mathematicians were less attributionally complex than nonmathematicians. Study 1 administered the Attributional Complexity Scale, a measure of social acuity, to female and male faculty members and graduate students in four Midwestern schools. Atlrihutional complexity (AC) is the ability and motivation to give complex explanations for behavior. Study 1 found a significant interaction between field and gender. Only among women did mathematicians score lower on AC. In addition, an established gender difference in AC (that women score higher than men) was present only among nonmathematicians. Studies 2 and 3 offered some preliminary support for the possibility that it is generally female students who score tow on AC who aspire to he mathematicians and for the underlying view that female students' perceived similarity to mathematicians can influence their vocational choices.

Full Text Available Do we have to drag in the thought of Michel Foucault to show the political (and not neutral, partial and local (and not universal and non-historic, active (and not merely transmissive face of science communication? Do we need the work of the controversial French intellectual to dispute the anxious search – almost a quest like that for the Holy Grail – for the “best practices” in the dissemination of scientific culture? If we read over the pages that Foucault dedicated to words and things, to the archaeology and genealogy of knowledge, to biopolitics, we have few doubts. Two elements, on the one hand the central nature of discourse and “regimes of truth”, on the other the concept of biopower (a “power over bodies”, enable us to reflect both on the important specific features of modern science in comparison with other forms of production and organisation of knowledge, and on the central role of its communication.
Presidents' words - Michel Goossens
Staff Association
2015-01-01
Michel Goossens Already at the beginning of 1955, just a few months after the creation of CERN, the members of the Organization's staff who then numbered less than 200, realized that they had to organize themselves into a corporate body to ensure a formal representation with Management and Member States. The Staff Association was born. As the 27th President of the Staff Association since its inception 60 years ago my task is highly interesting and rewarding, with plenty of responsibility, yet not always simple. Indeed, chosen by one’s peers as primus inter pares, the president is like the conductor of an orchestra, who must first convince his musicians to study the score together, before playing it in harmony. Of course, in my position I can rely on the solid foundations laid by my 26 predecessors, as well as the enthusiasm, loyalty, continuous efforts and perseverance of a core of dedicated collaborators, the elected delegates to the Staff Council.

Several prototypical distributions of finite-time Lyapunov exponents have been computed for the two-dimensional Henon-Heiles Hamiltonian system. Different shapes are obtained for each dynamical state. Even when an evolution is observed in the morphology of the distributions for the smallest integration intervals, they can still serve for characterizing the dynamical state of the system
Periodic orbits and non-integrability of Henon-Heiles systems
International Nuclear Information System (INIS)
Llibre, Jaume; Jimenez-Lara, Lidia
2011-01-01
We apply the averaging theory of second order to study the periodic orbits for a generalized Henon-Heiles system with two parameters, which contains the classical Henon-Heiles system. Two main results are shown. The first result provides sufficient conditions on the two parameters of these generalized systems, which guarantee that at any positive energy level, the Hamiltonian system has periodic orbits. These periodic orbits form in the whole phase space a continuous family of periodic orbits parameterized by the energy. The second result shows that for the non-integrable Henon-Heiles systems in the sense of Liouville-Arnol'd, which have the periodic orbits analytically found with averaging theory, cannot exist any second first integral of class C 1 . In particular, for any second first integral of class C 1 , we prove that the classical Henon-Heiles system and many generalizations of it are not integrable in the sense of Liouville-Arnol'd. Moreover, the tools we use for studying the periodic orbits and the non-Liouville-Arnol'd integrability can be applied to Hamiltonian systems with an arbitrary number of degrees of freedom.

Unlike the majority of Michel parameters which are consistent with the Standard Model V-A interaction, the experimental value of ξ''(=0.65±0.36) [1] is poorly known. Our experiment will measure the longitudinal polarization, P L , of positrons emitted from the decay of polarized muons. The value of P L , equal to unity in the Standard Model, will decrease for high energy positrons emitted antiparallel to the muon spin if the combination of Michel parameters ξ''/ξξ' - 1 deviates from the Standard Model value of zero
Symmetries in nature the scientific heritage of Louis Michel
Todorov, Ivan; Zhilinskii, Boris
2014-01-01
Reflecting the oeuvre of “a man of two cultures: the culture of pure mathematics and the culture of theoretical physics” (in the words of his long time friend and co-author, Kameshwar Wali), this volume is centred around the notion of symmetry and its breaking. Starting with particle physics, the content proceeds to symmetries of matter, defects, and crystals. The mathematics of group extensions, non-linear group action, critical orbits and phase transitions is developed along the way. The symmetry principles and general mathematical tools provide unity in the treatment of different topics. The papers and lecture notes are preceded by a lively biography of Louis Michel and a commentary that relates his selected works both to the physics of his time and to contemporary trends. This book should be of interest to theoretical physicists, chemists, applied mathematicians and historians of science, and is accessible to graduate (and advanced undergraduate) students.

Medical education... meet Michel Foucault.
Hodges, Brian D; Martimianakis, Maria A; McNaughton, Nancy; Whitehead, Cynthia
2014-06-01
There have been repeated calls for the greater use of conceptual frameworks and of theory in medical education. Although it is familiar to few medical educators, Michel Foucault's work is a helpful theoretical and methodological source. This article explores what it means to use a 'Foucauldian approach', presents a sample of Foucault's historical-genealogical studies that are relevant to medical education, and introduces the work of four researchers currently undertaking Foucauldian-inspired medical education research. Although they are not without controversy, Foucauldian approaches are employed by an increasing number of scholars and are helpful in shedding light on what it is possible to think, say and be in medical education. Our hope in sharing this Foucauldian work and perspective is that we might stimulate a dialogue that is forward-looking and optimistic about the possibilities for change in medical education. © 2014 John Wiley & Sons Ltd.
Quantum chaos in the Henon-Heiles oscillator under intense laser fields. IT-1

Gupta, Neetu; Deb, B.M.
2004-01-01
Full text: The quantum domain behaviour of the classically chaotic Henon-Heiles oscillator (HHO) has been studied earlier by several workers, without invoking either a weak or strong time- dependent external perturbation. This work looks at the motion of an electron moving in the HH potential under intense laser fields. The time-dependent Schroedinger equation is numerically solved in order to study the sensitivity of the system to initial conditions. The similarities in responses between the HHO and atoms/molecules to intense laser fields are examined; from this one might speculate that atoms/molecules in intense laser fields might exhibit quantum chaos
A Chaotic Cryptosystem for Images Based on Henon and Arnold Cat Map
Sundararajan, Elankovan
2014-01-01
The rapid evolution of imaging and communication technologies has transformed images into a widespread data type. Different types of data, such as personal medical information, official correspondence, or governmental and military documents, are saved and transmitted in the form of images over public networks. Hence, a fast and secure cryptosystem is needed for high-resolution images. In this paper, a novel encryption scheme is presented for securing images based on Arnold cat and Henon chaotic maps. The scheme uses Arnold cat map for bit- and pixel-level permutations on plain and secret images, while Henon map creates secret images and specific parameters for the permutations. Both the encryption and decryption processes are explained, formulated, and graphically presented. The results of security analysis of five different images demonstrate the strength of the proposed cryptosystem against statistical, brute force and differential attacks. The evaluated running time for both encryption and decryption processes guarantee that the cryptosystem can work effectively in real-time applications. PMID:25258724

The boundaries of golden-mean Siegel disks in the complex quadratic H\\'enon family are not smooth
Yampolsky, Michael; Yang, Jonguk
2016-01-01
As was recently shown by the first author and others, golden-mean Siegel disks of sufficiently dissipative complex quadratic H\\'enon maps are bounded by topological circles. In this paper we investigate the geometric properties of such curves, and demonstrate that they cannot be $C^1$-smooth.
Existe sujeito em Michel Maffesoli?
Directory of Open Access Journals (Sweden)
Marli Appel da Silva
2010-06-01
Full Text Available Este ensaio discute a concepção de sujeito na abordagem teórica de Michel Maffesoli. As ideias desse autor estão em voga em alguns meios acadêmicos no Brasil e são difundidas por algumas mídias de grande circulação nacional. Entretanto, ao longo de suas obras, os pressupostos que definem quem é o sujeito maffesoliano se encontram pouco clarificados. Portanto, para alcançar o objetivo a que se propõe, este ensaio desenvolve uma análise da epistemologia e da ontologia maffesoliana com a finalidade de compreender as origens dos pressupostos desse autor, ou seja, as teorias e os autores em que Maffesoli se baseou para desenvolver uma visão de sujeito. Com essa compreensão, pretende-se responder à questão: existe sujeito na abordagem teórica de Maffesoli.
Art in the life of mathematicians
Atiyah, Michael Francis
2015-01-01
I have always admired the abstraction ability of composers. The ingenious construction of beautiful patterns that can evoke such powerful emotions seems nothing short of magical. While mathematicians too construct beautiful patterns, I fear that few outside the math community appreciate that beauty or find any magic in it. I hope that this wonderful collection of articles, written by mathematicians who are themselves artists, will help better explain the many varied connections between mathematics and the arts, and illuminate better the beauty and magic in math. -Avi Wigderson, Institute for A

Poder disciplinario y capitalismo en Michel Foucault
Directory of Open Access Journals (Sweden)
Mauro Benente
2017-07-01
Full Text Available Establishing a relationship between the studies of Karl Marx and the research of Michel Foucault is not an easy task. There are readings describing the differences; others might emphasize the similarities while some others criticize Foucault’s developments from a Marxist perspective. In my present work I try to clarify the linkage between the disciplinary power and capitalism of Michel Foucault’s work within the context of the above-mentioned complexities. According to my proposed reading, capitalism does not explain the emergence of the disciplinary power, even if the production and accumulation of capital have applied disciplinary technics.
Recollections of a jewish mathematician in Germany
2016-01-01
Abraham A. Fraenkel was a world-renowned mathematician in pre–Second World War Germany, whose work on set theory was fundamental to the development of modern mathematics. A friend of Albert Einstein, he knew many of the era’s acclaimed mathematicians personally. He moved to Israel (then Palestine under the British Mandate) in the early 1930s. In his autobiography Fraenkel describes his early years growing up as an Orthodox Jew in Germany and his development as a mathematician at the beginning of the twentieth century. This memoir, originally written in German in the 1960s, has now been translated into English, with an additional chapter covering the period from 1933 until his death in 1965 written by the editor, Jiska Cohen-Mansfield. Fraenkel describes the world of mathematics in Germany in the first half of the twentieth century, its origins and development, the systems influencing it, and its demise. He also paints a unique picture of the complex struggles within the world of Orthodox Jewry in Germany....
The Albanian Mathematicians by the Flowside of the Mathematicians of the World
Kllogjeri, Pellumb
2014-01-01
I have had opportunities to see several world enciclopedies but I have found none of the Albanian mathematicians. Sure, can be found some great historical figures of Albania from the ancient world to the present time, even the names of cruel persons(this is ridicilous). But, how is it possible that no name of an Albanian mathematician is there? Does someone think that all that mathematical seed sown in Albania in different times, in different ways and by different sowers is dried out? Is n...
Peter Lax, mathematician an illustrated memoir
Hersh, Reuben
2015-01-01
Hersh's memoir of Peter Lax is a revealing glimpse into the life, times, and work of one of the giants of mathematics. The story, told through reminiscences and interviews with Lax himself, his family, and his close friends, is the story of mathematics and its relationships to science and society from the Second World War to the end of the century. -Charlie Epstein, University of Pennsylvania This book is a biography of one of the most famous and influential living mathematicians, Peter Lax. He is virtually unique as a preeminent leader in both pure and applied mathematics, fields which are o
Vector analysis for mathematicians, scientists and engineers
Simons, S
1970-01-01
Vector Analysis for Mathematicians, Scientists and Engineers, Second Edition, provides an understanding of the methods of vector algebra and calculus to the extent that the student will readily follow those works which make use of them, and further, will be able to employ them himself in his own branch of science. New concepts and methods introduced are illustrated by examples drawn from fields with which the student is familiar, and a large number of both worked and unworked exercises are provided. The book begins with an introduction to vectors, covering their representation, addition, geome
On mathematicians' different standards when evaluating elementary proofs.
Inglis, Matthew; Mejia-Ramos, Juan Pablo; Weber, Keith; Alcock, Lara
2013-04-01
In this article, we report a study in which 109 research-active mathematicians were asked to judge the validity of a purported proof in undergraduate calculus. Significant results from our study were as follows: (a) there was substantial disagreement among mathematicians regarding whether the argument was a valid proof, (b) applied mathematicians were more likely than pure mathematicians to judge the argument valid, (c) participants who judged the argument invalid were more confident in their judgments than those who judged it valid, and (d) participants who judged the argument valid usually did not change their judgment when presented with a reason raised by other mathematicians for why the proof should be judged invalid. These findings suggest that, contrary to some claims in the literature, there is not a single standard of validity among contemporary mathematicians. Copyright © 2013 Cognitive Science Society, Inc.
Mathematician for all seasons recollections and notes
Szymaniec, Irena; Weron, Aleksander; Shenitzer, Abe
2015-01-01
This book presents, in his own words, the life of Hugo Steinhaus (1887–1972), noted Polish mathematician of Jewish background, educator, and mathematical popularizer. A student of Hilbert, a pioneer of the foundations of probability and game theory, and a contributor to the development of functional analysis, he was one of those instrumental to the extraordinary flowering of Polish mathematics before and after World War I. In particular, it was he who “discovered” the great Stefan Banach. Exhibiting his great integrity and wit, Steinhaus’s personal story of the turbulent times he survived – including two world wars and life postwar under the Soviet heel – cannot but be of consuming interest. His recounting of the fearful years spent evading Nazi terror is especially moving. The steadfast honesty and natural dignity he maintained while pursuing a life of demanding scientific and intellectual enquiry in the face of encroaching calamity and chaos show him to be truly a mathematician for all seasons. ...

Clairambault, Jean
2011-12-01
I will present here a personal point of view on the commitment of mathematicians in medicine. Starting from my personal experience, I will suggest generalisations including favourable signs and caveats to show how mathematicians can be welcome and helpful in medicine, both in a theoretical and in a practical way.
Nonstandard analysis for the working mathematician
Wolff, Manfred
2015-01-01
Starting with a simple formulation accessible to all mathematicians, this second edition is designed to provide a thorough introduction to nonstandard analysis. Nonstandard analysis is now a well-developed, powerful instrument for solving open problems in almost all disciplines of mathematics; it is often used as a ‘secret weapon’ by those who know the technique. This book illuminates the subject with some of the most striking applications in analysis, topology, functional analysis, probability and stochastic analysis, as well as applications in economics and combinatorial number theory. The first chapter is designed to facilitate the beginner in learning this technique by starting with calculus and basic real analysis. The second chapter provides the reader with the most important tools of nonstandard analysis: the transfer principle, Keisler’s internal definition principle, the spill-over principle, and saturation. The remaining chapters of the book study different fields for applications; each begins...
Statistics for mathematicians a rigorous first course
Panaretos, Victor M
2016-01-01
This textbook provides a coherent introduction to the main concepts and methods of one-parameter statistical inference. Intended for students of Mathematics taking their first course in Statistics, the focus is on Statistics for Mathematicians rather than on Mathematical Statistics. The goal is not to focus on the mathematical/theoretical aspects of the subject, but rather to provide an introduction to the subject tailored to the mindset and tastes of Mathematics students, who are sometimes turned off by the informal nature of Statistics courses. This book can be used as the basis for an elementary semester-long first course on Statistics with a firm sense of direction that does not sacrifice rigor. The deeper goal of the text is to attract the attention of promising Mathematics students.
Emeritus Scientists, Mathematicians and Engineers (ESME) program
Energy Technology Data Exchange (ETDEWEB)
Sharlin, H.I.
1992-09-01
The Emeritus Scientists, Mathematicians and Engineers (ESME) program matches retired scientists and engineers with wide experience with elementary school children in order to fuel the children's natural curiosity about the world in which they live. The long-range goal is to encourage students to maintain the high level of mathematical and science capability that they exhibit at an early age by introducing them to the fun and excitement of the world of scientific investigation and engineering problem solving. Components of the ESME program are the emeriti, established teacher-emeriti teams that work to produce a unit of 6 class hours of demonstration or hands-on experiments, and the encounter by students with the world of science/engineering through the classroom sessions and a field trip to a nearby plant or laboratory.
Amongst mathematicians teaching and learning mathematics at university level
Nardi, Elena
2008-01-01
"Amongst Mathematicians" offers a unique perspective on the ways in which mathematicians perceive their students' learning, the way they teach and reflect on those teaching practices. Elena Nardi employs fictional characters to create a conversation on these important issues. While personas are created, the facts incorporated into their stories are based on large bodies of data including intense focus groups comprised of mathematicians and mathematics education.This book further develops analyses of the data and demonstrates the pedagogical potential that lies in collaborative research that engages educators, researchers, and students in undergraduate mathematics education. Nardi also addresses the need for action in undergraduate mathematics education by creating discourse for reform and demonstrating the feasibility and potential of collaboration between mathematicians and researchers. "Amongst Mathematicians" is of interest to the entire mathematics community including teacher educators, undergraduate and ...
Michele Ferro-Luzzi (1938-2015)
2015-01-01
We have learned with great sorrow of the passing away, on 11 May, of Michele Ferro-Luzzi, an engineer well-known to many physicists working at CERN from the late 1960s to the early 2000s. Michele was born in Rome in 1938. He attended primary and secondary schools in Asmara (Eritrea), where his family had moved to in 1939, and then he went to the University of Rome where he obtained a "laurea" in electronic engineering in 1962. After completing his military service he was hired by CERN, in 1965, in the applied physics group, created by the Nuclear Physics (NP) Division Leader, Peter Preiswerk, to support physics teams in the design and construction of detectors, which were becoming more and more complex at that time. Michele’s primary interest was the design of particle beams. He became an expert in beam optics and in all kinds of beam components. For twenty-five years he was the best-known member of his group, involved in nearly all its&nb...

Full Text Available RESUMEN El cementerio es uno de los tipos arquitectónicos más profundos y metafóricos. El concurso para la ampliación del cementerio de San Michele, convocado en 1998 por la administración Municipal de Venecia, se convierte en un excelente campo de pruebas sobre el que poder analizar el contexto histórico en torno a esta tipología, y su relación con la ciudad y el territorio. El estudio de este caso concreto nos permite descubrir personajes, relaciones casuales y hallazgos que se despliegan a lo largo del texto. La historia del cementerio de San Michele es también la crónica de la transformación de la ciudad de Venecia y su Laguna. Interpretando este concurso como un instrumento de investigación, el objetivo del artículo es el de comprender la realidad contemporánea de la arquitectura funeraria a través de la isla de San Michele, Venecia, y las propuestas finalistas de Carlos Ferrater, Enric Miralles y David Chipperfield. Una historia bajo la cual se vislumbran claves que nos sirven para reflexionar acerca del cementerio contemporáneo, la ciudad y el territorio. SUMMARY The cemetery is one of the most profound and metaphorical kinds of architecture. The competition for the extension of the San Michele Cemetery, called in 1998 by the Venice municipal administration, is an excellent testing ground on which to analyse the historical context surrounding this type of architecture, and its relationship with the city and the region. The study of this particular case allows us to uncover characters, casual relationships and findings that unfold throughout the text. The history of the San Michele cemetery is also the chronicle of the transformation of the city of Venice and its Lagoon. Interpreting this competition as a research tool, the aim of the paper is to understand the contemporary reality of funerary architecture through the island of San Michele, Venice, and the finalist proposals of Carlos Ferrater, Enric Miralles and David
Quantum field theory a tourist guide for mathematicians
Folland, Gerald B
2008-01-01
Quantum field theory has been a great success for physics, but it is difficult for mathematicians to learn because it is mathematically incomplete. Folland, who is a mathematician, has spent considerable time digesting the physical theory and sorting out the mathematical issues in it. Fortunately for mathematicians, Folland is a gifted expositor. The purpose of this book is to present the elements of quantum field theory, with the goal of understanding the behavior of elementary particles rather than building formal mathematical structures, in a form that will be comprehensible to mathematicians. Rigorous definitions and arguments are presented as far as they are available, but the text proceeds on a more informal level when necessary, with due care in identifying the difficulties. The book begins with a review of classical physics and quantum mechanics, then proceeds through the construction of free quantum fields to the perturbation-theoretic development of interacting field theory and renormalization theor...
Women Mathematicians = Kadın Matematikçiler

Ali DÖNMEZ
2001-01-01
Full Text Available In any book on the history of mathematics, mention about women mathematicians is hardly found. One wonders if there were any and, if any, why so few? The lives of some women mathematicians from different countries, the first who was born in 370 AD and the last who died in 1935. If there were only a few women mathematicians before the 20th Century, why have there been more in the 21th century what has been done, and what is being done, to increase their number? There is no enough space in this paper to examine the details of the mathematical research being conducted by these eight women. Instead the main interest will be the difficulties involved and the struggles they underwent while fulfilling their desire to become mathematicians, the first one of them who had a tragic end.
Poder y resistencia en Michel Foucault
Directory of Open Access Journals (Sweden)
Reinaldo Giraldo Díaz
2006-01-01
Full Text Available En este artículo se analizan los conceptos de poder y resistencia en las obras del período genealógico de Michel Foucault, es decir, después de El orden del discurso, texto programático y hasta el primer volumen de Historia de la Sexualidad. La voluntad de saber. El artículo realiza sobre todo una elaboración de las concepciones de Foucault sobre el poder y la resistencia en las sociedades disciplinarias y en las sociedades de control. Contrario a lo que sostienen los críticos de Foucault, en este artículo se considera que la resistencia no es negativa, ni reactiva. Nuestra hipótesis de trabajo es que para el pensador francés la resistencia es creativa, productiva y anterior al poder.

Coelho, Leandro dos Santos; Mariani, Viviana Cocco
2009-01-01
Particle swarm optimization (PSO) is a population-based swarm intelligence algorithm driven by the simulation of a social psychological metaphor instead of the survival of the fittest individual. Based on the chaotic systems theory, this paper proposed a novel chaotic PSO combined with an implicit filtering (IF) local search method to solve economic dispatch problems. Since chaotic mapping enjoys certainty, ergodicity and the stochastic property, the proposed PSO introduces chaos mapping using Henon map sequences which increases its convergence rate and resulting precision. The chaotic PSO approach is used to produce good potential solutions, and the IF is used to fine-tune of final solution of PSO. The hybrid methodology is validated for a test system consisting of 13 thermal units whose incremental fuel cost function takes into account the valve-point loading effects. Simulation results are promising and show the effectiveness of the proposed approach.
Michel Houellebecq : un homme, une (soumission
Directory of Open Access Journals (Sweden)
Marc Smeets
2015-12-01
Full Text Available Michel Houellebecq, l’auteur le plus controversé de la littérature française contemporaine, semble s’astreindre à une seule et unique mission : celle d’être « vrai » à n’importe quel prix. Observateur et peintre de la société actuelle dans tous ses états, l’auteur de Soumission s’inscrit dans une tradition littéraire qui remonte au XIXe siècle, prolongeant ainsi les fictions de Balzac, de Zola et de Huysmans. De ses prédécesseurs Houellebecq hérite d’un certain goût pour la controverse, talent qui fait naturellement la pluie et le beau temps dans la presse. Le rôle que jouent la documentation et la figure du célibataire permet de situer l’écrivain dans le sillage de la tradition réalistico-naturaliste.
Michel Houellebecq and the International Sexual Economy
Directory of Open Access Journals (Sweden)
Douglas Morrey
2004-01-01
Full Text Available This paper explores the notion of an ‘international sexual economy’ in the work of the French writer Michel Houellebecq, and particularly his latest novel, Plateforme (2001. Houellebecq suggests that, since westerners no longer have the time or the inclination to sleep with each other, and since those in the third world have nothing to sell but their bodies, the exchange of cash for sex on a truly international scale is likely to represent the most lucrative sector of the global economy in the coming century. Whilst acknowledging the objections to this idea, the paper shows how it is based in a serious analysis of global capitalism which has something in common with the theoretical work of Jean-François Lyotard, in terms of both the postmodern and the libidinal economies. The paper further suggests that the virulent anti-psychologism of Houellebecq’s often brutal worldview implies a (largely undeclared kinship with Friedrich Nietzsche. Finally, it offers an analysis of the ironic narrative strategies in Plateforme that are interpreted as the consequence of trying to criticize the cultural economy without being able to position oneself outside it.
Words of gratitude to Dr. Michel Huguet
International Nuclear Information System (INIS)

2003-01-01
It is impossible for the Japanese fusion community, in particular for those associated with the ITER Project,to hear about the retirement of Dr. Michel Huguet without a great amount of gratitude, recollections, warm feelings, and the inevitable sadness. He was a first-generation ITER EDA person. Three months after the signing of the ITER EDA Agreement in July 1992, he arrived at the Naka Joint Work Site as Deputy Director of the ITER Central Team and Head of the site and he stayed for more than ten years. The Naka site was for design and technical co-ordination in the areas of magnets, plasma control and heating, plant systems, buildings, etc. Dr. Huguet was considered a highly qualified person to fill the position, since he had been successful as Deputy Director in similar areas in the JET Joint Undertaking. During the ITER EDA he co-ordinated the R and D activities in areas for which the Naka Joint Work Site was responsible. These R and D results permitted the completion of the ITER design in the above areas under his supervision. We thank Dr. Huguet for his achievements and contributions to ITER. He played a crucial role in establishing the convincing scientific and technical basis for ITER implementation. This was only made possible by his broad abilities and his dedication to the cause of fusion in general and ITER in particular

The Michel parameters of the leptonic tau decays are measured using the OPAL detector at LEP. The Michel parameters are extracted from the energy spectra of the charged decay leptons and from their energy-energy correlations. A new method involving a global likelihood fit of Monte Carlo generated events with complete detector simulation and background treatment has been applied to the data recorded at center-of-mass energies close to sqrt(s) = M(Z) corresponding to an integrated luminosity of 155 pb-1 during the years 1990 to 1995. If e-mu universality is assumed and inferring the tau polarization from neutral current data, the measured Michel parameters are extracted. Limits on non-standard coupling constants and on the masses of new gauge bosons are obtained. The results are in agreement with the V-A prediction of the Standard Model.

Here we study the relaxation of a chain consisting of three masses joined by nonlinear springs and periodic conditions when the stiffness is weakened. This system, when expressed in their normal coordinates, yields a softened Henon-Heiles system. By reducing the stiffness of one low-frequency vibrational mode, a faster relaxation is enabled. This is due to a reduction of the energy barrier heights along the softened normal mode as well as for a widening of the opening channels of the energy landscape in configurational space. The relaxation is for the most part exponential, and can be explained by a simple flux equation. Yet, for some initial conditions the relaxation follows as a power law, and in many cases there is a regime change from exponential to power-law decay. We pinpoint the initial conditions for the power-law decay, finding two regions of sticky states. For such states, quasiperiodic orbits are found since almost for all components of the initial momentum orientation, the system is trapped inside two pockets of configurational space. The softened Henon-Heiles model presented here is intended as the simplest model in order to understand the interplay of rigidity, nonlinear interactions and relaxation for nonequilibrium systems such as glass-forming melts or soft matter. Our softened system can be applied to model β relaxation in glasses and suggest that local reorientational jumps can have an exponential and a nonexponential contribution for relaxation, the latter due to asymmetric molecules sticking in cages for certain orientations.
An outline of ethics on the work of Michel Foucault

An outline of ethics on the work of Michel Foucault The French philosopher Michel Foucault is well known for his critical thinking and for his genealogies of the human subject. In these analyzes power and knowledge (power-knowledge) plays a decisive role. For Foucault power-knowledge is the very...... (Kelly (edt.) 1994). Nevertheless, Foucault ended his academic career discussing ethics in the form of ethos (Foucault 1994). In this form his ethical project approaches an aesthetic project in the form of the individual’s self-creation. In my presentation I will introduce Foucault’s concept of ethos...... and discuss the possibilities and limitations in this position. In addition, I will argue that his insistently critical stance and power-knowledge concept can be considered as an ethical stance different from both deontology and utilitarism. As such, it could have an important impact on the practice...

How mathematicians think using ambiguity, contradiction, and paradox to create mathemathics
Byers, William
2007-01-01
To many outsiders, mathematicians appear to think like computers, grimly grinding away with a strict formal logic and moving methodically--even algorithmically--from one black-and-white deduction to another. Yet mathematicians often describe their most important breakthroughs as creative, intuitive responses to ambiguity, contradiction, and paradox. A unique examination of this less-familiar aspect of mathematics, How Mathematicians Think reveals that mathematics is a profoundly creative activity and not just a body of formalized rules and results

n a recent article, Inglis and Alcock (2012) contended that their data challenge the claim that when mathematicians validate proofs, they initially skim a proof to grasp its main idea before reading individual parts of the proof more carefully. This result is based on the fact that when mathematicians read proofs in their study, on average their…

The training to acquire or practicing to perform a skill, which may lead to structural changes in the brain, is called experience-dependent structural plasticity. The main purpose of this cross-sectional study was to investigate the presence of experience-dependent structural plasticity in mathematicians' brains, which may develop after long-term practice of mathematic thinking. Twenty-six volunteer mathematicians, who have been working as academicians, were enrolled in the study. We applied an optimized method of voxel-based morphometry in the mathematicians and the age- and sex-matched control subjects. We assessed the gray and white matter density differences in mathematicians and the control subjects. Moreover, the correlation between the cortical density and the time spent as an academician was investigated. We found that cortical gray matter density in the left inferior frontal and bilateral inferior parietal lobules of the mathematicians were significantly increased compared with the control subjects. Furthermore, increase in gray matter density in the right inferior parietal lobule of the mathematicians was strongly correlated with the time spent as an academician (r = 0.84; P mathematicians' brains revealed increased gray matter density in the cortical regions related to mathematic thinking. The correlation between cortical density increase and the time spent as an academician suggests experience-dependent structural plasticity in mathematicians' brains.

The life-cycle research productivity of mathematicians and scientists.
Diamond, A M
1986-07-01
Declining research productivity with age is implied by economic models of life-cycle human capital investment but is denied by some recent empirical studies. The purpose of the present study is to provide new evidence on whether a scientist's output generally declines with advancing age. A longitudinal data set has been compiled for scientists and mathematicians at six major departments, including data on age, salaries, annual citations (stock of human capital), citations to current output (flow of human capital), and quantity of current output measured both in number of articles and in number of pages. Analysis of the data indicates that salaries peak from the early to mid-60s, whereas annual citations appear to peak from age 39 to 89 for different departments with a mean age of 59 for the 6 departments. The quantity and quality of current research output appear to decline continuously with age.

Using the ARGUS detector at the DORIS II e + e - storage ring we have studied the electron and muon energy spectra in τ - →e - νanti ν and τ - →μ - νanti ν. The measured value of the Michel parameter, ρ=0.742±0.035±0.020, is in good agreement with a standard V-A coupling at the τ-ν τ -W vertex. Pure V, A and V+A couplings are completely excluded by this measurement. Upper limits have been obtained for two-body tau decays, including final states with a Goldstone boson. (orig.)

[Michel Foucault and the persistence of psychiatric power].
Caponi, Sandra
2009-01-01
This article aims studying the course held by Michel Foucault at the Collège de France in 1973-1974. The records of this course were published in 2003 under the name ' Psychiatric power' . The objective was to compare the different ways in which Foucault analyzes the question of madness in ' Psychiatric power' and in ' History of Madness in the Classical Age' (1961). It is a comparative study about the different ways of analyzing madness developed by Michel Foucault during the archeological and genealogic periods of his work. The absence of the body; binary diagnosis; the description of the surface of symptoms; the classification of diseases more similar to the botanical classification than to pathology; the process of cure directly linked to restitution of behaviors and moral values; as well as the over-power of the psychiatrist, seem to speak about the persistence of an old model of power, a pre-modern and pre-capitalist model, a residue of the old sovereign power.

Introduction to Louis Michel's lattice geometry through group action
Zhilinskii, Boris
2015-01-01
Group action analysis developed and applied mainly by Louis Michel to the study of N-dimensional periodic lattices is the central subject of the book. Different basic mathematical tools currently used for the description of lattice geometry are introduced and illustrated through applications to crystal structures in two- and three-dimensional space, to abstract multi-dimensional lattices and to lattices associated with integrable dynamical systems. Starting from general Delone sets the authors turn to different symmetry and topological classifications including explicit construction of orbifolds for two- and three-dimensional point and space groups. Voronoï and Delone cells together with positive quadratic forms and lattice description by root systems are introduced to demonstrate alternative approaches to lattice geometry study. Zonotopes and zonohedral families of 2-, 3-, 4-, 5-dimensional lattices are explicitly visualized using graph theory approach. Along with crystallographic applications, qualitative ...

On the (non-)optimality of Michell structures

Sigmund, Ole; Aage, Niels; Andreassen, Erik
2016-01-01
Optimal analytical Michell frame structures have been extensively used as benchmark examples in topology optimization, including truss, frame, homogenization, density and level-set based approaches. However, as we will point out, partly the interpretation of Michell’s structural continua...... as discrete frame structures is not accurate and partly, it turns out that limiting structural topology to frame-like structures is a rather severe design restriction and results in structures that are quite far from being stiffness optimal. The paper discusses the interpretation of Michell’s theory...... in the context of numerical topology optimization and compares various topology optimization results obtained with the frame restriction to cases with no design restrictions. For all examples considered, the true stiffness optimal structures are composed of sheets (2D) or closed-walled shell structures (3D...
[The birth of acknowledgement: Michel Foucault and Werner Leibbrand].
Mildenberger, Florian
2006-01-01
In 1964, Werner Leibbrand (1896-1974) was the first German medical historian to present, in Sudhoffs Archiv, a review of the work of Michel Foucault (1926-1984). This paper examines some of the reasons leading to the fact that Leibbrand's own generation refused to acknowledge the importance of Foucault's ideas, while, later on, younger German medical historians, although impressed with Foucault's writings, failed to acknowledge, first, the close relationship between Leibbrand's and Foucault's world views, and, second, Leibbrand's attempts at introducing Foucault to German medical historians. Leibbrand with his Jewish wife had survived the Nazi period partly in hiding. His attempts at clearing post-war German psychiatry and medical historiography of NS-sympathizers isolated him among his colleagues, many of whom had begun their career during the Third Reich. Leibbrand enjoyed the support by the Swiss medical historian and avowed Communist Erwin Ackerknecht (1906-1988), but later turned against him, possibly because Acknerknecht had called Leibbrand's writings "unscientific". Leibbrand was unable to overcome his antagonisms with his contemporaries. At the same time, opposition to Ackerknecht made him appear a respresentative of the past in the eyes of the younger generation. Thus, when Foucault was accepted by the latter, they were not prepared to examine the work of Leibbrand and realize how close some of the ideas developed by Leibbrand and Foucault had been.
A measurement of the tau Michel parameters at SLD

Quigley, J.
1997-05-01
This thesis presents a measurement of the tau Michel parameters. This measurement utilizes the highly polarized SLC electron beam to extract these quantities directly from the measured tau decay spectra using the 1993--95 SLD sample of 4,528 tau pair events. The results are ρ e = 0.71 ± 0.14 ± 0.05, ξ e = 1.16 ± 0.52 ± 0.06, and (ξδ) e = 0.85 ± 0.43 ± 0.08 for tau decays to electrons and ρ μ = 0.54 ± 0.28 - 0.14, η μ = -0.59 ± 0.82 ± 0.45, ξ μ = 0.75 ± 0.50 ± 0.14, and (ξδ) μ = 0.82 ± 0.32 ± 0.07 for tau decays to muons. Combining all leptonic tau decays gives ρ = 0.72 ± 0.09 ± 0.03, ξ = 1.05 ± 0.35 ± 0.04, and Ξδ = 0.88 ± 0.27 ± 0.04. These results agree well with the current world average and the Standard Model

Professional mathematicians differ from controls in their spatial-numerical associations.
Cipora, Krzysztof; Hohol, Mateusz; Nuerk, Hans-Christoph; Willmes, Klaus; Brożek, Bartosz; Kucharzyk, Bartłomiej; Nęcka, Edward
2016-07-01
While mathematically impaired individuals have been shown to have deficits in all kinds of basic numerical representations, among them spatial-numerical associations, little is known about individuals with exceptionally high math expertise. They might have a more abstract magnitude representation or more flexible spatial associations, so that no automatic left/small and right/large spatial-numerical association is elicited. To pursue this question, we examined the Spatial Numerical Association of Response Codes (SNARC) effect in professional mathematicians which was compared to two control groups: Professionals who use advanced math in their work but are not mathematicians (mostly engineers), and matched controls. Contrarily to both control groups, Mathematicians did not reveal a SNARC effect. The group differences could not be accounted for by differences in mean response speed, response variance or intelligence or a general tendency not to show spatial-numerical associations. We propose that professional mathematicians possess more abstract and/or spatially very flexible numerical representations and therefore do not exhibit or do have a largely reduced default left-to-right spatial-numerical orientation as indexed by the SNARC effect, but we also discuss other possible accounts. We argue that this comparison with professional mathematicians also tells us about the nature of spatial-numerical associations in persons with much less mathematical expertise or knowledge.

Mathematics delivering the advantage: the role of mathematicians in manufacturing and beyond.
Saward, Vicki
2017-05-01
Much has been written about the benefits that mathematics can bring to the UK economy and the manufacturing sector in particular, but less on the value of mathematicians and a mathematical training. This article, written from an industry perspective, considers the value of mathematicians to the UK's industrial base and the importance to the UK economy of encouraging young people in the UK to choose to study mathematics at school as a gateway to a wide range of careers. The points are illustrated using examples from the author's 20 years' experience in the security and intelligence and manufacturing sectors.

The Experimental Mathematician: The Pleasure of Discovery and the Role of Proof
Borwein, Jonathan M.
2005-01-01
The emergence of powerful mathematical computing environments, the growing availability of correspondingly powerful (multi-processor) computers and the pervasive presence of the Internet allow for mathematicians, students and teachers, to proceed heuristically and "quasi-inductively." We may increasingly use symbolic and numeric computation,…

Full Text Available Although mathematicians frequently use specialist software in direct teaching ofmathematics, as a means of delivery e-learning technologies have so far been lesswidely used. We (mathematicians insist that teaching methods should be subjectspecificand content-driven, not delivery-driven. We oppose generic approaches toteaching, including excessively generalist, content-free, one-size-fits-allpromotion of information and communications technology. This stance is fullyexpressed, for example, in the recent Teaching Position Statement from the LondonMathematical Society (2010 and is supported by a recent report from the NationalUnion of Students (2010, 5: “Not every area of study needed or was compatiblewith e-learning, and so to assume it would grant blanket advantages was notaccurate”. This paper is an attempt to explain mathematicians' selectivity in use ofinformation and communications technology and its guiding principles. The paperis addressed to our non-mathematician colleagues and is not intended to be a surveyof the existing software and courseware for mathematics teaching – the corpus ofexisting solutions is enormous and its discussion inevitably involves hardcoremathematics.
On the role of visual experience in mathematical development: Evidence from blind mathematicians.
Amalric, Marie; Denghien, Isabelle; Dehaene, Stanislas
2018-04-01
Advanced mathematical reasoning, regardless of domain or difficulty, activates a reproducible set of bilateral brain areas including intraparietal, inferior temporal and dorsal prefrontal cortex. The respective roles of genetics, experience and education in the development of this math-responsive network, however, remain unresolved. Here, we investigate the role of visual experience by studying the exceptional case of three professional mathematicians who were blind from birth (n=1) or became blind during childhood (n=2). Subjects were scanned with fMRI while they judged the truth value of spoken mathematical and nonmathematical statements. Blind mathematicians activated the classical network of math-related areas during mathematical reflection, similar to that found in a group of sighted professional mathematicians. Thus, brain networks for advanced mathematical reasoning can develop in the absence of visual experience. Additional activations were found in occipital cortex, even in individuals who became blind during childhood, suggesting that either mental imagery or a more radical repurposing of visual cortex may occur in blind mathematicians.

Several techniques are available to measure red cell cholinesterase; therefore, evaluations with several methods provide a measure of concordance. An equation was formulated to transform native data of reference values to reference units of cholinesterase activity as measured by Michel and EQM tests. The experimental design was descriptive, transversal and prospective. The group sampled was a representative adult working population, aged 18-75, without previous exposure to cholinesterase inhibitors pesticides. The individuals were affiliated to the Social Security System and resided in Valle de Aburrá and Cercano Oriente Antioqueño (Antioquia Province, northwestern Colombia). Of 827 individuals, quantitative erythrocytes (Michel y EQM) tests exhibited "r" coefficients between 0.67 and R2 coefficient of 44%.,This indicated that one test explained the results in other test in 44% of the cases. The corelation was higher in Aburrá than in Oriente. The linear model for the 827 individuals was as follows: EQM U/g oxy-hemoglobin = 9.575 U/ g oxy-hemoglobin + 29.791 (Michel delta pH/hour). Michel delta pH/hr = 0.3312 delta pH/hour + 0.0149 (EQM U/g oxy-hemoglobin), where EQM was expressed in U/g oxy-hemoglobin and Michel pH change/hr. Inter-sections (coefficient a) and inclines (coefficient b) were significant in this model. In the adjusted equations, after exclusion of 12 extreme data (1.5% of 827), the r coefficient increased from 0.67 to 0.72 The adjusted equations were as follows: EQM U/g oxy-hemoglobin = 8.1884 U/g oxy-hemoglobin + 31.3920 (Michel delta pH/hour); Michel delta pH/hr = 0.2925 delta pH/hr + 0.0161 (EQM U/g oxy-hemoglobin). This system of linear equations permitted the transformation of Michel (delta PH/ hr) units to EQM (U/g oxy-hemoglobin) units and vice versa. This will facilitate data comparisons by clinicians and epidemiologists who are using these methods of cholinesterase measurement.
Simulacra, Symbolic Exchange and Technology in Michel Tournier's La Goutte d'Or

Full Text Available In La Goutte d'Or , Michel Tournier offers a critique of Western culture by constructing a novel that reflects both Jean Baudrillard's theories of simulacra and the political economy of the sign and Martin Heidegger's meditations on technology. Tournier's novel explores the relationship between Heidegger's explanation of technology as an act of Enframing ( Ge-stell and Baudrillard's description of an economy based upon exchange-sign value. Thus, through La Goutte d 'Or , Michel Tournier depicts the violent confrontation between a symbolic exchange economy based on poietic acts and late capitalist economies of autonomized signs.
Role of mathematics in cancer research: attitudes and training of Japanese mathematicians.

An extensive survey of attitude towards scientific information of scientists in Japan was conducted in Japan. It was published in a technical report, and this survey is reviewed in this paper, with the hope that this will furnish findings important in working out the plan for promoting exploitation of mathematical talent in biomedical research. Findings are concordant with the impression of foreign visitors: (1) pure mathematicians tend to concentrate on mathematics only; (2) applied mathematics and statistics are heavily oriented toward industry; (3) mathematicians and pharmacologists are very different in their attitudes to scientific information. Based on the personal experience of the author, difficulties to be circumvented in utilizing aptitudes for mathematics and/or statistics in biomedical research are discussed. PMID:540605

Origins of the brain networks for advanced mathematics in expert mathematicians.
Amalric, Marie; Dehaene, Stanislas
2016-05-03
The origins of human abilities for mathematics are debated: Some theories suggest that they are founded upon evolutionarily ancient brain circuits for number and space and others that they are grounded in language competence. To evaluate what brain systems underlie higher mathematics, we scanned professional mathematicians and mathematically naive subjects of equal academic standing as they evaluated the truth of advanced mathematical and nonmathematical statements. In professional mathematicians only, mathematical statements, whether in algebra, analysis, topology or geometry, activated a reproducible set of bilateral frontal, Intraparietal, and ventrolateral temporal regions. Crucially, these activations spared areas related to language and to general-knowledge semantics. Rather, mathematical judgments were related to an amplification of brain activity at sites that are activated by numbers and formulas in nonmathematicians, with a corresponding reduction in nearby face responses. The evidence suggests that high-level mathematical expertise and basic number sense share common roots in a nonlinguistic brain circuit.

These congresses arose at the end of the 19-th century, being the last step on the professionalizing process of mathematical research. Its meetings have gathered all areas of mathematical research, exhibiting the best mathematics of the moment, and honouring the great mathematicians from the past. Prizes associated to ICMs have had a very important role, in particular, the Fields medal. The history of the congresses allow to appreciate how the rooted feeling among mathematicians of constituting a scientific research community has aided ICMs to overcome all the tragic events of the history of the 20-th century, arriving safely to the 25-th congress in Madrid in 2006.En este artículo se repasa la historia de los International Congress of Mathematicians (ICM.

Abraham Pais Prize for History of Physics Talk: Henry Cavendish, John Michell, Weighing the Stars
McCormmach, Russell
2010-03-01
This talk is about an interaction between two 18th-century natural philosophers (physical scientists), Henry Cavendish and John Michell, and its most important outcome, the experiment of weighing the world (their name for it) using a torsion balance (our name for it). Michell was the most inventive of the 18th century English natural philosophers, and Cavendish was the first of his countrymen to possess abilities at all comparable with Newton's. By their interests and skills, they were drawn to one another. Both were universal natural philosophers, equally adept at building scientific instruments, performing experiments, constructing theory, and using mathematics; both had a penchant for exacting, quantitative work. Both also had fitful habits of publication, which did not begin to reveal the range of their work, to the mystification of later scientists and historians. Late in life, Cavendish and Michell turned their attention to the force that Newton had examined most completely, a singular triumph of his natural philosophy, the force of universal gravitation. Over the course of the 18th century, abundant evidence of attraction had been gathered from the motions of the earth, moon, planets, and comets, phenomena which span the intermediate range of masses, sizes, and distances. But in three domains of experience, involving the extreme upper and lower limits of masses and dimensions, the universality of gravitation remained an article of faith. These were the gravity of the ``fixed'' stars, the mutual attraction of terrestrial bodies, and the gravitation of light and other special substances. Michell took on himself the task of deducing observable consequences from each of these prospective instances of universal gravitation. Cavendish encouraged Michell, and he followed up the resulting observational and experimental questions. The experiment of weighing the world was the last experiment Mitchell planned and the last experiment Cavendish published. The capstone of

Several types of hydraulic turbines can be used in small hydroelectric power plant, as Pelton, Francis, Turgo, Kaplan, Propeller, Banki, etc. In Brazil the more used are Francis and Kaplan followed by Pelton. The usage of the other types is almost unknown, mainly the Turgo turbine. The cross flow turbine, also known by the names of Michell-Banki, Banki, and Michell-Ossberger is defined as an action turbine that can be applicable to falls from 1 to 200 m and flows from 0,025 to 13 m{sup 3}/s. With the technical evolution mainly in the last two decades by traditional firms like Ossberger Turbinenfabrik and new firms like CINK, that turbine can reach diameters of rotors of 1,0 m with width of 2,6 m and to develop capacity up to 2,000 k W, with efficiency near 90%. The main evolutions are concentrated in modifications presented in the injector of the turbine by several manufacturers, and the use of new materials in the blades of the runner, shafts, bearings and the use of the draft tube. Case study shows the technical and economical implications using a cross flow turbine in comparison to a Francis turbine and a Kaplan. The conclusions will be reported after technical and economical viability analysis among the three types of turbines. (author)

Michel Borghini as a Mentor and Father of the Theory of Polarization in Polarized Targets
de Boer, Wim
2016-02-01
This paper is a contribution to the memorial session for Michel Borghini at the Spin 2014 conference in Bejing, honoring his pivotal role for the development of polarized targets in high energy physics. Borghini proposed for the first time the correct mechanism for dynamic polarization in polarized targets using organic materials doped with free radicals. In these amorphous materials the spin levels are broadened by spin-spin interactions and g-factor anisotropy, which allows a high dynamic polarization of nuclei by cooling of the spin-spin interaction reservoir. In this contribution I summarize the experimental evidence for this mechanism. These pertinent experiments were done at CERN in the years 1971 - 1974, when I was a graduate student under the guidance of Michel Borghini. I finish by shortly describing how Borghini’s spin temperature theory is now applied in cancer therapy.

Très bien documenté, son chantier dévoile un mobilier et un décor exemplaire par son homogénéité et par la place accordée à la peinture murale. Cette étude met en évidence, outre le rôle du peintre Alphonse Colas, des artistes méconnus comme Albéric Duyver et Marie Carin. L’iconographie, qui révèle un des plus importants cycles consacrés à l’archange saint Michel, est également extrêmement caractéristique de son temps.After the demolition of the fortifications at Lille, in 1858, a new quarter developed to the south of the city. One of the important features of this new neighbourhood was the Saint-Michel church, built between 1868 and 1874 to the designs of the architect Alfred Coisel. The building of this church is exceptionally well documented and reveals church furnishings and decoration of an exemplary nature in terms of homogeneity and the special place given over to mural paintings. This study underlines the role of the painter Alphonse Colas, but also the contribution of other, less well known artists such as Albéric Duyver and Marie Carin. The iconographical theme is one of the most important cycles of its time devoted to the archangel Saint Michel, and is highly characteristic of the period.

This is a book that the author wishes had been available to him when he was student. It reflects his interest in knowing (like expert mathematicians) the most relevant mathematics for theoretical physics, but in the style of physicists. This means that one is not facing the study of a collection of definitions, remarks, theorems, corollaries, lemmas, etc. but a narrative - almost like a story being told - that does not impede sophistication and deep results. It covers differential geometry far beyond what general relativists perceive they need to know. And it introduces readers to other areas
The ballet of the planets a mathematician's musings on the elegance of planetary motion
Benson, Donald
2012-01-01
The Ballet of the Planets unravels the beautiful mystery of planetary motion, revealing how our understanding of astronomy evolved from Archimedes and Ptolemy to Copernicus, Kepler, and Newton. Mathematician Donald Benson shows that ancient theories of planetary motion were based on the assumptions that the Earth was the center of the universe and the planets moved in a uniform circular motion. Since ancient astronomers noted that occasionally a planet would exhibit retrograde motion--would seem to reverse its direction and move briefly westward--they concluded that the planets moved in epicyc

The development of new and sophisticated Monte Carlo codes and tomographic human phantoms or voxels motivated the International Commission on Radiological Protection (ICRP) to revise the traditional models of exposure, which have been used to calculate effective dose coefficients for organs and tissues based on mathematician phantoms known as MIRD5. This paper shows the results of calculations using tomographic phantoms MAX (Male Adult voXel) and FAX (Female Adult voXel), recently developed by the authors as well as with the phantoms ADAM and EVA, of specific genres, type MIRD5, coupled to the EGS4 Monte Carlo and MCNP4C codes, for internal exposure with photons of energies between 10 keV and 4 MeV to several organs sources. Effective Doses for both models, tomographic and mathematician, will be compared separately as a function of the Monte Carlo code replacement, of compositions of human tissues and the anatomy reproduced through tomographs. The results indicate that for photon internal exposure, the use of models of exposure based in voxel, increases the values of effective doses up to 70% for some organs sources considered in this study, when compared with the corresponding results obtained with phantoms of MIRD-5 type
Bruno de Finetti: the mathematician, the statistician, the economist, the forerunner.
Rossi, C
2001-12-30
Bruno de Finetti is possibly the best known Italian applied mathematician of the 20th century, but was he really just a mathematician? Looking at his papers it is always possible to find original and pioneering contributions to the various fields he was interested in, where he always put his mathematical "formamentis" and skills at the service of the applications, often extending standard theories and models in order to achieve more general results. Many contributions are also devoted to educational issues, in mathematics in general and in probability and statistics in particular.He really thought that mathematics and, in particular, those topics related to uncertainty, should enter in everyday life as a useful support to everyone's decision making. He always imagined and lived mathematics as a basic tool both for better understanding and describing complex phenomena and for helping decision makers in assuming coherent and feasible actions. His many important contributions to the theory of probability and to mathematical statistics are well known all over the world, thus, in the following, minor, but still pioneering, aspects of his work, related both to theory and to applications of mathematical tools, and to his work in the field of education and training of teachers, are presented.

Michel Durand-Delga made a success of an outstanding career in geology. His route might be considered as one of a pioneer of a new kind. He set a meticulous rhythm in this discipline of the Earth sciences, particularly in Algeria, the country he loved for its geology, landscapes and population. The first of his fructuous works was published in 1948 on the geology of the Petite Kabylie and he continued, for most his life, to work very closely on this zone which he characterized, in a definitive way, as different from the African continent with at first structural then stratigraphical evidence. He highlighted the Kabylian thrust where the northern domain (internal, also called Kabyle) overlaps a southern domain (external or African). All the geological information that came later either produced by him or later by his students and opponents supported this great hypothesis which today has become a reliable paradigm. (Author)

Full Text Available In the frame of Quebec literature, Michel Tremblay’s poetics is an attempt to transfiguration of plebeian axiology in high literature, universal in scope. The slang of the Montreal periphery (so called joual and its speakers, which are mostly marginal characters, are highlighted by the application of the principles of religious drama, Greek tragedy and opera as the constituent parts of Tremblay’s theater and prose. To identify and illustrate these principles at different structural levels, the paper analyses the novels Le Premier Quartier de la lune (1989, Le cahier noir (2003, La Traversée de la ville (2008 and the drama Sainte Carmen de la Main (1976.

Literary Practice according to Michel Henry: A Philosophical Introduction to his Novels

Full Text Available Although the author of four novels, Michel Henry never produced an aesthetics of literature. The purpose of this article is, after a presentation of his philosophy of immanence and his concept of life, to locate where the literary practice takes place in his system. In this study, we are not interested in the poetic quality of his works, but in the possibility to base his singular creativity on his philosophical reflection. This leads us to insert literature in the vast phenomenon of culture and ethics, and to grasp the function of poetics in the struggle against barbarism.

The Crystal Ball detector at the Doris II storage ring at DESY has been used to study the electron energy spectrum of the decay τ→eνanti ν. In the standard model the Lorentz structure of the decay matrix element is of the well known V-A type, resulting in a Michel parameter of ρ=0.75. Our spectrum is found to be consistent with this value. A fit yields the value of 0.64±0.06±0.07. (orig.)

The Emeritus Scientists, Mathematicians and Engineers (ESME) program matches retired scientists and engineers with wide experience with elementary school children in order to fuel the children`s natural curiosity about the world in which they live. The long-range goal is to encourage students to maintain the high level of mathematical and science capability that they exhibit at an early age by introducing them to the fun and excitement of the world of scientific investigation and engineering problem solving. Components of the ESME program are the emeriti, established teacher-emeriti teams that work to produce a unit of 6 class hours of demonstration or hands-on experiments, and the encounter by students with the world of science/engineering through the classroom sessions and a field trip to a nearby plant or laboratory.

The aim of this paper is to examine the iconography on a set of star charts by Albrecht Dürer (1515), and celestial globes by Caspar Vopel (1536) and Christoph Schissler (1575). The iconography on these instruments is conditioned by strong traditions which include not only the imagery on globes and planispheres (star charts), but also ancient literature about the constellations. Where this iconography departs from those traditions, the change had to do with humanism in the sixteenth century. This "humanistic" dimension is interwoven with other concerns that involve both "social" and "technical" motivations. The interplay of these three dimensions illustrates how the iconography on celestial charts and globes expresses some features of the shared knowledge and shared culture between artisans, mathematicians, and nobles in Renaissance Europe.
The mathematician's mind the psychology of invention in the mathematical field
Hadamard, Jacques
1996-01-01
Fifty years ago when Jacques Hadamard set out to explore how mathematicians invent new ideas, he considered the creative experiences of some of the greatest thinkers of his generation, such as George Polya, Claude Lévi-Strauss, and Albert Einstein. It appeared that inspiration could strike anytime, particularly after an individual had worked hard on a problem for days and then turned attention to another activity. In exploring this phenomenon, Hadamard produced one of the most famous and cogent cases for the existence of unconscious mental processes in mathematical invention and other forms of creativity. Written before the explosion of research in computers and cognitive science, his book, originally titled The Psychology of Invention in the Mathematical Field, remains an important tool for exploring the increasingly complex problem of mental life. The roots of creativity for Hadamard lie not in consciousness, but in the long unconscious work of incubation, and in the unconscious aesthetic selection of ide...
Numbers and functions from a classical-experimental mathematician's point of view
Moll, Victor H
2012-01-01
New mathematics often comes about by probing what is already known. Mathematicians will change the parameters in a familiar calculation or explore the essential ingredients of a classic proof. Almost magically, new ideas emerge from this process. This book examines elementary functions, such as those encountered in calculus courses, from this point of view of experimental mathematics. The focus is on exploring the connections between these functions and topics in number theory and combinatorics. There is also an emphasis throughout the book on how current mathematical software can be used to discover and prove interesting properties of these functions. The book provides a transition between elementary mathematics and more advanced topics, trying to make this transition as smooth as possible. Many topics occur in the book, but they are all part of a bigger picture of mathematics. By delving into a variety of them, the reader will develop this broad view. The large collection of problems is an essential part of...

Il razzismo come strategia di difesa sociale. Michel Foucault e le forme attuali del biopotere
Directory of Open Access Journals (Sweden)
Maura Simone
2010-01-01
Full Text Available Racism as a Social Defense Strategy. Michel Foucault and Current Forms of Biopower - During his lessons held at the College de France in 1976 Michel Foucault presents a genealogy of two types of narratives, concerning respectively war and race theory, considered in their historical development from the XVIth Century. Foucault’s work Il faut défendre la société outlines a specific model for the function of race theory, seen as a technique of normalization of diversity, and not longer as an “exceptional event” produced by the “totalitarian” narratives which arose in the XXth Century. This paper aims to stress the actuality of Foucault’s position, trying to show how the concept of bio-power, already at work in these lessons, deserves an active and productive role in the analysis of contemporary “democratic” societies, because of the structure of their internal cohesion, based on strategies developing “inclusion”/“exclusion” dynamics.
[A non-classical approach to medical practices: Michel Foucault and Actor-Network Theory].
Bińczyk, E
2001-01-01
The text presents an analysis of medical practices stemming from two sources: Michel Foucault's conception and the research of Annemarie Mol and John Law, representatives of a trend known as Actor-Network Theory. Both approaches reveal significant theoretical kinship: they can be successfully consigned to the framework of non-classical sociology of science. I initially refer to the cited conceptions as a version of non-classical sociology of medicine. The identity of non-classical sociology of medicine hinges on the fact that it undermines the possibility of objective definitions of disease, health and body. These are rather approached as variable social and historical phenomena, co-constituted by medical practices. To both Foucault and Mol the main object of interest was not medicine as such, but rather the network of medical practices. Mol and Law sketch a new theoretical perspective for the analysis of medical practices. They attempt to go beyond the dichotomous scheme of thinking about the human body as an object of medical research and the subject of private experience. Research on patients suffering blood-sugar deficiency provide the empirical background for the thesis of Actor-Network Theory representatives. Michel Foucault's conceptions are extremely critical of medical practices. The French researcher describes the processes of 'medicalising' Western society as the emergence of a new type of power. He attempts to sensitise the reader to the ethical dimension of the processes of medicalising society.
Banki-Michell Optimal Design by Computational Fluid Dynamics Testing and Hydrodynamic Analysis
Directory of Open Access Journals (Sweden)
Tullio Tucciarelli
2013-04-01
Full Text Available In hydropower, the exploitation of small power sources requires the use of small turbines that combine efficiency and economy. Banki-Michell turbines represent a possible choice for their simplicity and for their good efficiency under variable load conditions. Several experimental and numerical tests have already been designed for examining the best geometry and optimal design of cross-flow type machines, but a theoretical framework for a sequential design of the turbine parameters, taking full advantage of recently expanded computational capabilities, is still missing. To this aim, after a review of the available criteria for Banki-Michell parameter design, a novel two-step procedure is described. In the first step, the initial and final blade angles, the outer impeller diameter and the shape of the nozzle are selected using a simple hydrodynamic analysis, based on a very strong simplification of reality. In the second step, the inner diameter, as well as the number of blades and their shape, are selected by testing single options using computational fluid dynamics (CFD simulations, starting from the suggested literature values. Good efficiency is attained not only for the design discharge, but also for a large range of variability around the design value.

The Desire for Knowledge as an Incentive for Life in Community, following Michel de Montaigne
Directory of Open Access Journals (Sweden)
Víctor H. Palacios Cruz
2015-12-01
Full Text Available A tendency towards truth indicates an inclination towards being in tune with the world and inserting one’s own life within it. It is a process that requires the concurrence of other viewpoints, fragmentary and diverse, the incorporation of which ensures the objectivity of knowledge and respects the richness of what it is real. Knowledge requires habits of coexistence and communication that establish a common space for equality and plurality in exchanges. Michel de Montaigne, in the troubled sixteenth century, celebrated the pleasure of discussion and exhorted people to travel as a form of avoiding personal pride and increasing their being through the encounter. A loyal search for truth in conjunction with courtesy in controversy would entail the promotion of civic virtues beyond mere tolerance and bring about attitudes of mutual interest, cordiality, dialogue, inclusion and care for that which is common.
MICHEL FOUCAULT AND THE FINANCIAL GOVERNABILITY REFLECTIONS ON THE INTERNATIONAL FINANCIAL CRISIS
Directory of Open Access Journals (Sweden)
Juan Omar, Agüero
2010-01-01
Full Text Available In this paper I present a governability or power technology form what I call financial governability that differs from the German ordoliberalism and the North American anacor-liberalism, analyzed by Michel Foucault. In which context does this form emerge from financial rationality?, how does it emerge and develop itself?, what meanings has it got for biopolítics and governability? And what implications happen from this transformation process of the human work in financial capital?, these are some of the matters that are discussed in this paper. As from the concepts of biopolítics and governability, I treat the theories of the policy of society and human capital, as foundations of the German ordoliberalism and the North American anarco-liberalism, respectively, later discussing the governability form which I call financial governability, as power technology differentiated from those.

The non-place as a tourist destination in Michel Houellebecq’s Plateforme
Directory of Open Access Journals (Sweden)
Ana Filipa Prata
2014-11-01
Full Text Available This paper discusses the representation of mass tourism in Michel Houellebecq’s Plateform (2001 in relation to the concept of “non-place” defining the “supermodern” spaces proliferating in the globalized world deprived from historical, identitary and relational values. As the universe of tourism is the central element of the novel’s plot, we shall look at how it takes the form of a dysphoric configuration of a certain idea of travel, and how the language of simulacra, in which hotels airports constitute transfer platforms of the same capitalistic order, is sustaining it. Through the analysis of the production and consumption mechanisms of adventure circuits and vacation clubs, that slip inside the field of sexual tourism in Thailand, this book exposes ironically an alienated occidental society looking for an escape to everyday life in exotic destinations and à la carte sojourns.
Lungo le vie di pellegrinaggio: la lezione astronomica di Gerberto a San Michele della Chiusa
Paladino, Laura C.
A pilgrim on the trails of the Earth: that's how Gerbertus appears to us in the years preceding his pontificate as well in those, brief and intense, in which he was Pope. An ardent pilgrim of faith moved at the same time by vast intellectual interests that allowed him to come into contact with the most important schools of the time, of any cultural tradition; a pilgrim full of love, willing to transmit the enormous heritage of faith and knowledge of which he was custodian. The presence of the illustrious Benedictine is not explicitly documented in the Abbey of San Michele della Chiusa, but the signs of its cultural and ideological influence are evident both in historical memory as in the artistical vestiges of the Sacra: we investigate here, this presence, authoritative, original and versatile, to outline another aspect, still little investigated, of the lesson of Gerbert, monk, scientist, teacher and pastor.
Michel de Certeau and the Admirabile Commercium of Meanings in Education
Directory of Open Access Journals (Sweden)
Fabio Botelho Josgrilberg
2008-07-01
Full Text Available This paper aims at reflecting upon Michel de Certeau’s relationship with education. Even though the issue is marginal to his other fields of interest, such as history, religion and culture, the challenges he presents are inspiring for educators at varying levels and from different fields of knowledge. Certeau’s thought moving power is the movement towards other ones, fostered by ethical and epistemological demands; a movement which opens itself to the possibility that each encounter may reveal something new. The movement is born from the refusal of literal meanings or existing hierarchies, without falling into irresponsible relativism which denies his own memory. With Certeau we learn to see schools or universities as places of crossing paths, bricolage and operations which escape from established references.
Harmonies of disorder Norbert Wiener : a mathematician-philosopher of our time
Montagnini, Leone
2017-01-01
This book presents the entire body of thought of Norbert Wiener (1894–1964), knowledge of which is essential if one wishes to understand and correctly interpret the age in which we live. The focus is in particular on the philosophical and sociological aspects of Wiener’s thought, but these aspects are carefully framed within the context of his scientific journey. Important biographical events, including some that were previously unknown, are also highlighted, but while the book has a biographical structure, it is not only a biography. The book is divided into four chronological sections, the first two of which explore Wiener’s development as a philosopher and logician and his brilliant interwar career as a mathematician, supported by his philosophical background. The third section considers his research during World War II, which drew upon his previous scientific work and reflections and led to the birth of cybernetics. Finally, the radical post-war shift in Wiener’s intellectual path is considered, e...
Gregory Bateson and the mathematicians: from interdisciplinary interaction to societal functions.
Heims, S P
1977-04-01
An instance of fruitful cross-disciplinary contacts is examined in detail. The ideas involved include (1) the double-blind hypothesis for schizophrenia, (2) the critique of game theory from the viewpoint of anthropology and psychiatry, and (3) the application of concepts of communication theory and theory of logical types to an interpretation of psychoanalytic practice. The protagonists of the interchange are Gregory Bateson and the two mathematicians Norbert Wiener and John von Neumann; the date, March 1946. This interchange and its sequels are described. While the interchanges between Bateson and Wiener were fruitful, those between Bateson and von Neumann were much less so. The latter two held conflicting premises concerning what is significant in science; Bateson's and Wiener's were compatible. In 1946, Wiener suggested that information and communication might be appropriate central concepts for psychoanalytic theory--a vague general idea which Bateson (with Ruesch) related to contemporary clinical practice. For Bateson, Wiener, and von Neumann, the cross-disciplinary interactions foreshadowed a shift in activities and new roles in society, to which the post World War II period was conducive. Von Neumann became a high-level government advisor; Wiener, an interpreter of science and technology for the general public; and Bateson a counter-culture figure.
Yeast for Mathematicians: A Ferment of Discovery and Model Competition to Describe Data.
Lewis, Matthew; Powell, James
2017-02-01
In addition to the memorization, algorithmic skills and vocabulary which are the default focus in many mathematics classrooms, professional mathematicians are expected to creatively apply known techniques, construct new mathematical approaches and communicate with and about mathematics. We propose that students can learn these professional, higher-level skills through Laboratory Experiences in Mathematical Biology which put students in the role of mathematics researcher creating mathematics to describe and understand biological data. Here we introduce a laboratory experience centered on yeast (Saccharomyces cerevisiae) growing in a small capped flask with a jar to collect carbon dioxide created during yeast growth and respiration. The lab requires no specialized equipment and can easily be run in the context of a college math class. Students collect data and develop mathematical models to explain the data. To help place instructors in the role of mentor/collaborator (as opposed to jury/judge), we facilitate the lab using model competition judged via Bayesian Information Criterion. This article includes details about the class activity conducted, student examples and pedagogical strategies for success.
Quantum field theory III. Gauge theory. A bridge between mathematicians and physicists

Zeidler, Eberhard
2011-01-01
In this third volume of his modern introduction to quantum field theory, Eberhard Zeidler examines the mathematical and physical aspects of gauge theory as a principle tool for describing the four fundamental forces which act in the universe: gravitative, electromagnetic, weak interaction and strong interaction. Volume III concentrates on the classical aspects of gauge theory, describing the four fundamental forces by the curvature of appropriate fiber bundles. This must be supplemented by the crucial, but elusive quantization procedure. The book is arranged in four sections, devoted to realizing the universal principle force equals curvature: Part I: The Euclidean Manifold as a Paradigm Part II: Ariadne's Thread in Gauge Theory Part III: Einstein's Theory of Special Relativity Part IV: Ariadne's Thread in Cohomology For students of mathematics the book is designed to demonstrate that detailed knowledge of the physical background helps to reveal interesting interrelationships among diverse mathematical topics. Physics students will be exposed to a fairly advanced mathematics, beyond the level covered in the typical physics curriculum. Quantum Field Theory builds a bridge between mathematicians and physicists, based on challenging questions about the fundamental forces in the universe (macrocosmos), and in the world of elementary particles (microcosmos).

The most interesting section of the portal is Journals, which combines Russian periodical and continuous publications in the mathematical sciences as a unified information system. The portal structure and its diverse opportunities and tools available for information searches are described. A survey of similar Russian and foreign systems is presented. This article is aimed at the wide community of mathematicians ready to use new information technologies in their research. Technical details of the system's realization are omitted, and attention is focused rather on a description of the users' possibilities.
Michel Foucault et Paul Ricœur, vers un dialogue possible

Full Text Available Il est désormais connu que Michel Foucault s’est intéressé à la fin de sa vie à l’ ”herméneutique du sujet.” Mais cette histoire de la constitution du sujet (ou de la subjectivité fait étrangement l’économie d’une réflexion sur le rôle de la compréhension, alors que Foucault qualifie son travail d’ ”ontologie historique de nous-mêmes.” C'est sur ce point précis qu’est ici mis à l'épreuve le caractère médiateur de l’œuvre de Paul Ricœur, dont l’herméneutique du soi prend en charge une ontologie de la compréhension. Suite à ces considérations, la seconde partie de l’article cherche à démontrer que la théorie de l’agir de Ricœur peut favoriser le passage d’une reconnaissance de type objectale à une reconnaissance des capacités du sujet à se tenir pour responsable. Ce passage sera opéré directement sur le modèle d’analyse du “dernier Foucault,” c’est-à-dire son concept-clé de “processus de subjectivation.”In his later work, Michel Foucault manifested a strong interest for the “hermeneutics of the subject.” Yet this history of the constitution of the subject (or subjectivity does without any reflection on the role of understanding, even though Foucault characterizes his project as a historical ontology of ourselves. The power of mediation emphasized in the work of Paul Ricœur may help us redefine an ontology of understanding through a hermeneutics of the self. Following this, the second part of the article aims to show that Ricœur’s theory of action can facilitate a transition from the recognition of the self, first described as “objectivation,” to a recognition of the subject’s capacity to be held responsible. This passage will draw on the model of analysis in the later Foucault, specifically, on his key concept of the subjectivation process.

Nella linea di faglia rappresentata dal primo conflitto mondiale, i due sociologi sono in una doppia relazione interiore appunto franco-italiana Pareto e italo-tedesca Michels e una relazione esteriore fra il mondo di ieri e il mondo successivo al cataclisma che fu la prima guerra mondiale, quando ben quattro imperi colossali erano stati smembrati (l’Impero Russo, l’Impero Tedesco, l’Impero Austro-ungarico e l’Impero ottomano, nello stesso tempo in cui Emile Durkheim guardava con inquietudine alla disgregazione delle vecchie comunità tradizionali, dove il senso della crisi del tempo investe non solo le persone e i comportamenti, ma il mondo logico stesso. Lo scambio epistolare avviene nella stessa terra: Pareto a Celigny, sul lago di Ginevra , e Michels a Basilea , lungo le rive del Reno. Vi è, fra i due sociologi un profondo rispetto, che vedrà Robert Michels dedicare allo “scienziato e amico Vilfredo Pareto con venerazione” un’opera importante come “Problemi di sociologia applicata” pubblicata solo tre anni dopo il Trattato di Sociologia Generale del Maestro. In questa antologia di saggi Robert Michels, probabilmente composti fra il 1914 e il 1917, negli anni del grande cataclisma, anzi concepiti prima «dell’insediamento di questa terribile corte suprema di cassazione di tutte le nostre ideologie, che è la guerra» , quindi contemporanea al Trattato, il Maestro viene citato tre volte, come Max Weber, ma, de facto, la presenza di Pareto è continua. In particolare, il richiamo al Maestro è iscritto a due piste di ricerca: da una parte la realtà della ricerca sociologica e del suo amplissimo spettro di analisi e dall’altra la teoria della circolazione delle elités.

Full Text Available La losofía de Michel Foucault ha sido una de las influencias más importantes que el siglo XX ha ejercido sobre nuestro pensamiento político contemporáneo. Entre sus contribuciones, la noción de “biopoder” es notable tanto por el amplio espectro de problemas que ha señalado desde su creación por el pensador, cuanto por la flexibilidad con la que es capaz de cambiar su sentido en función del contexto de problematización en el que aparece. Para comprender cuál es el marco conceptual desde el que Foucault concibió esta noción en su Historia de la sexualidad, es necesario un trabajo de lectura atenta y análisis de las re exiones originales en torno a ella. Nuestra intención es prestar atención a cómo Foucault pensó el poder en sus cursos del Collège de France desde el inicio de la elabora- ción de Historia de la sexualidad.
Nacionalismos e internacionalismo: um debate entre Michael Löwy e Michel Cahen

Full Text Available Este artigo consiste em um debate realizado entre Michel Löwy e Michael Cahen em meados dos anos 1990 e revisto para esta publicação. Mesmo que a discussão refira-se a acontecimentos que até certo ponto podem ser considerados datados, a preocupação de fundo que é comum a esses artigos concede-lhes atualidade: a necessidade do aprofundamento de uma reflexão, a partir da teoria marxista, sobre o problema dos nacionalismos e do internacionalismo em tempos de mundialização. Esse aprofundamento, segundo os autores, faz-se necessário sobretudo por meio de uma reflexão que rompa criticamente com uma visão eurocêntrica dos diferentes nacionalismos e que supere a atitude de muitos marxistas de desprezarem tudo aquilo que não seja diretamente relevante à "consciência de classe".

The feature follows the Sanchification of Jerry (Jack Black, Gondry’s Don Quixote, and Quixotification of Mike (Mos Def, Gondry’s Sancho, as they nostalgically wrong cinematic rights through sweding and try to save their working-class neighbourhood from condemnation and gentrification through community film making. Gondry swedes the Quixote through his engagement with major themes and operations in Cervantes’s classic, including nostalgia, story-telling, conflicts between reality and fantasy, authorship, the grotesque and carnivalesque, (anti-heroes, race and gender-bending, genre, and addressees turned addressers. This article discusses Be Kind Rewind’s relationship to Hollywoodian and Cervantine classics through the theoretical frameworks of Julio Garcia Espinosa’s imperfect cinema and Foucauldian semiotics, respectively. Be Kind Rewind uses and abuses Hollywood stereotypes to re-purpose them for a critique of discriminatory practices. Where casting is concerned and where Michel’s characters diverge from Miguel’s, Be Kind Rewind advances that skin colour is not an arbitrary sign and that race has historical and contemporary meaning in intercultural interactions.

This place is also the location of the Egyptian Sphinx, half lion, half woman...... that the spirit of the place adjoins a metaphysical core of architecture; and as the very core of architecture could be connected to an absolute truth so it seems that genius loci is related to truth; even though it is a truth that is not directly visible. We ask in this paper if it is a truth that is perennially...... are going to hear the Sphinx ask us questions, all these riddling puzzles, we first have to ask the Sphinx to know how to ask questions. That genius loci are present in architectural theory owes much to the Scandinavian theoretician and architect Christian Norberg-Schulz, who emphasized considerations...
La Filosofía de Michel Serres: una Moral de Base Objetiva

Full Text Available Los temas que preocupan al filósofo francés Michel Serres son variados y, en cierto sentido, caóticos. Sin embargo, uno de los puntos esenciales de la filosofía del autor tiene como base empírica el problema de la moral, que el hombre deposita en los objetos tecnológicos en su proceso de elaboración. No es exagerado decir que el único propósito de su filosofía es el tema de la relación entre la ética y el desarrollo científico, que se manifestó con el uso de las bombas atómicas contra indefensos ciudadanos japoneses en la Segunda Guerra Mundial. El abordaje del tema de reflexión será el resultado de un camino explicativo que comienza por presentar la formación y el contexto de la obra del autor, continúa con la exposición de su método de trabajo y las nociones que integran el núcleo de su pensamiento. Al avanzar en esta propedéutica se analizarán sus nociones sobre la invención del futuro, el papel que en ella juega la tecnociencia y la necesidad de dotarla de una base moral.
The production of the psychiatric subject: power, knowledge and Michel Foucault.
Roberts, Marc
2005-01-01
The issue of power has become increasingly important within psychiatry, psychotherapy and mental health nursing generally. This paper will suggest that the work of Michel Foucault, the French philosopher and historian, has much to contribute to the discussion about the nature, existence and exercise of power within contemporary mental health care. As well as examining his original and challenging account of power, Foucault's emphasis on the intimate relationship between power and knowledge will be explored within the context of psychiatry and mental health nursing. This is to say that the paper will investigate Foucault's account of how power and knowledge are central to the process by which human beings are 'made subjects' and therefore how 'psychiatric identities' are produced. In doing so, it will be suggested that Foucault's work can not only make a valuable contribution to contemporary discussions about power and knowledge, but can also provide a significant critique and reconceptualization of the theoretical foundations and associated diagnostic and therapeutic practices of psychiatry and mental health nursing.

Critical thinking and contemporary mental health care: Michel Foucault's "history of the present".
Roberts, Marc
2017-04-01
In order to be able to provide informed, effective and responsive mental health care and to do so in an evidence-based, collaborative and recovery-focused way with those who use mental health services, there is a recognition of the need for mental health professionals to possess sophisticated critical thinking capabilities. This article will therefore propose that such capabilities can be productively situated within the context of the work of the French philosopher Michel Foucault, one of the most challenging, innovative and influential thinkers of the 20th century. However, rather than focusing exclusively upon the content of Foucault's work, it will be suggested that it is possible to discern a general methodological approach across that work, a methodological approach that he refers to as "the history of the present." In doing so, Foucault's history of the present can be understood as a productive, albeit provisional, framework in which to orientate the purpose and process of critical thinking for mental health professionals by emphasizing the need to both historicize and politicize the theoretical perspectives and therapeutic practices that characterize contemporary mental health care. © 2016 John Wiley & Sons Ltd.

Full Text Available In literature, questions of the self and the other are frequently presented. The identity politics that gained prominence after the attack on the World Trade Center in New York on 11 September 2001 has occupied considerable space in this debate throughout the globe, including in France. One example of a novel dealing with the self and other is Michel Houellebecq’s Soumission (2015. This article attempts to explore the processes of selfing and othering in this work. The politics of identity that seems to present Muslims and Islam as the other and French as the self is also extended to other identities and aspects involved in the novel. This article attempts to show, first, how the French author Houellebecq positions the self and other in Soumission; second, the type of self and other the novel focuses on; and third, how its selfing and othering processes reveal the gender hierarchy and social categorization of French society. It finds that the novel presents a hierarchy in its narrative through which characters are positioned based on their gender and sexual orientation, as well as their age and ethnic heritage.
Bodies spoken by the other: A reading of Michel de Certeau
Directory of Open Access Journals (Sweden)
Geraldo Luiz De Mori
2016-12-01
Full Text Available This article aims to schematize a reflection of Michel de Certeau regarding the various meanings attributed to the body by Ocidental culture, pointing out the resignifications of these meanings by the Christian religion. For this, in methodological terms, attention was given to interdisciplinary dialogue furthered by this author who easily moved among the fields of psychoanalysis, history, linguistics, philosophy, theology, and spirituality. As a first hypothesis, it postulated that for De Certeau the body is configured as a viable fiction of social practices, that is, an instance of authority capable of provoking agreements, conflicts and transformations. This is because, according to the aforementioned Jesuit, the body is constituted simultaneously both as a symbolic contribution to institutional powers as well as a mediation for political and cultural bricolage, departures and transgressions advanced in daily life. Concomitantly, it is considered, as a second hypothesis that, as indicated by De Certeau, the body in the Christian tradition was lived as a mystic instance, that is, as enunciating, by its manifestations, the desire to be habited by the other/Other. It is then suggested that an actualization of this existential and political condition now enables subjects to turn positive their intrinsic incompleteness and fragile humanness, favoring, as a result, historical and social experiences shared and felt.

Various aspects of this valuabe book collection have been studied lately. Books from this dispersed collection have been revealed and examined de visu. Their cataloguing incudes the description of individual book copies in view of their provenance. The purpose of the article is to provide the information on a complex of owners’ recordings and dedicatory inscriptions as well as bookplates left on the books making an attempt to trace the fate of the copies incorporated in the library of the Odessa mathematician. The information collected is considered in the context of the history of Mathematics. Many may characterise both direct and indirect expressions of the readers’ interests in books and reading. The study of provenance records demonstrate that the copies acquired by professor Timchenko used to be in the libraries of a number of men of science – mathematicians, physicists, philologists, etc. The findings of this article enable to enlarge the database of provenance making the practical value and results of the research.

Moving from Paris, Pisa, and Oxford to London, Amsterdam, and Cambridge, this essay documents extensive collaborations between anatomists and mathematicians. At a time when no standard way to acknowledge collaboration existed, it is remarkable that in all the cases I discuss anatomists expressed in print their debt to mathematicians. The cases I analyze document an extraordinarily fertile period in the history of anatomy and science and call into question historiographic divisions among historians of science and medicine. I focus on Steno's Myology, showing how his collaboration with mathematician Viviani led to a geometrical treatment of muscular contraction and to an epistemology inspired by Galileo. The collaboration between Steno and Viviani enables us to interpret a major text in the history of anatomy, one whose implications had so far eluded historians.

Não obstante, veio ganhar precisão teórica apenas em 1959, por Charles Ferguson. A partir da publicação do seu artigo, o conceito teve um sucesso imediato na Sociolinguística. Este artigo segue a esteira dessas discussões, com o objetivo de repensar o sujeito falante da “variedade baixa” ou “língua dominada”. Para tanto, valemo-nos da reflexão de Michel de Certeau (1994 sobre o cotidiano, especialmente das categorias de estratégia e de tática. Na primeira seção do artigo, traçamos um percurso pela história do termo diglossia, desde os seus significados nos primeiros testemunhos até a sua consolidação como conceito científico através de Ferguson (1959 e Fishman (1967. A seguinte é um encaminhamento à reflexão: expomos uma leitura crítica dos artigos mencionados e algumas críticas por parte de outros sociolinguistas. A terceira é o lugar de dar algumas informações sobre o caso de diglossia que serve de fundamento e ilustração à reflexão: a diglossia espanhol-catalão na Catalunha. Enfim, na quarta o leitor alcança a reflexão almejada: o sujeito falante da “variedade baixa” ou “língua dominada” não é um mero paciente em uma relação alto-baixo ou dominante-dominado, mas também um agente no campo hegemônico, que usa de táticas para contra-arrestar a dominação.

On the Bargmann-Michel-Telegdi equations, and spin-orbit coupling: A tribute to Raymond Stora
Duval, Christian
2016-11-01
The Bargmann-Michel-Telegdi equations describing the motions of a spinning, charged, relativistic particle endowed with an anomalous magnetic moment in an electromagnetic field, are reconsidered. They are shown to duly stem from the linearization of the characteristic distribution of a presymplectic structure refining the original one of Souriau. In this model, once specialized to the case of a static electric-like field, the angular momentum and energy given by the associated moment map now correctly restore the spin-orbit coupling term. This is the state-of-the-art of unfinished joint work with Raymond Stora.

Chen Jingrun (1933-1996), perhaps the most prodigious mathematician of his time, focused on the field of analytical number theory. His work on Waring's problem, Legendre's conjecture, and Goldbach's conjecture led to progress in analytical number theory in the form of "Chen's Theorem," which he published in 1966 and 1973. His early life was ravaged by the Second Sino-Japanese War and the Chinese Cultural Revolution. On the verge of solving Goldbach's conjecture in 1984, Chen was struck by a bicyclist while also bicycling and suffered severe brain trauma. During his hospitalization, he was also found to have Parkinson's disease. Chen suffered another serious brain concussion after a fall only a few months after recovering from the bicycle crash. With significant deficits, he remained hospitalized for several years without making progress while receiving modern Western medical therapies. In 1988 traditional Chinese medicine experts were called in to assist with his treatment. After a year of acupuncture and oxygen therapy, Chen could control his basic bowel and bladder functions, he could walk slowly, and his swallowing and speech improved. When Chen was unable to produce complex work or finish his final work on Goldbach's conjecture, his mathematical pursuits were taken up vigorously by his dedicated students. He was able to publish Youth Math, a mathematics book that became an inspiration in Chinese education. Although he died in 1996 at the age of 63 after surviving brutal political repression, being deprived of neurological function at the very peak of his genius, and having to be supported by his wife, Chen ironically became a symbol of dedication, perseverance, and motivation to his students and associates, to Chinese youth, to a nation, and to mathematicians and scientists worldwide.

En este trabajo se reflexiona, de manera bien introductoria, acerca de algunas preocupaciones planteadas por Michel Foucault, en especial lo que él llama disciplinalization y utopía del cuerpo. Deducimos que estos están influenciados por la filosofía post-sartreana, participan las afecciones resultantes a partir de mayo de 1968 y un retorno a la filosofía de Nietzsche. Este filósofo de la transgresión en tela de juicio los supuestos hasta ahora planteados por la filosofía perspectiva marxista, vinculadas al concepto de lucha de clases y militante función intelectual (Sartre, que pensar en el cuerpo y el poder. Por último, Foucault refleja cómo construir cierta sociedad disciplinaria, según las convenciones dadas paraliza el cuerpo, inventa y dominado por ciertos intereses permeadas por relaciones de micro-poder.

Full Text Available O presente trabalho visa problematizar a suposta constituição virtuosa entre educação e conhecimento oriunda de certa herança cultural da modernidade ocidental. A problemática ancora-se na indagação difusa, porém insistente, a ecoar no campo educacional: "o que é o ato do pensar, em educação, na contemporaneidade?". A tomada das condições atuais do pensamento como um problema de pesquisa educacional coloca em questão a histórica articulação entre conhecimento e pensamento reflexivo, obrigando ao confronto de certos amálgamas pedagógicos caros ao campo educacional moderno. Tal enfrentamento se realiza na companhia dos pensadores Michel Foucault e Friedrich Nietzsche, dada a relevância estratégica de suas produções, particularmente acerca da linguagem, da produção da verdade e de suas implicações nos modos de conhecer e pensar. Busca-se operacionalizar uma crítica da linguagem em direção a uma crítica do pensamento em educação, na chave de uma problematização ético-política. Nesse trabalho, tal plataforma analítica configura-se a partir das discussões de Michel Foucault - tanto em relação à questão do pensamento do fora, tal como elaborada por Maurice Blanchot, como em relação ao pensamento da diferença, tal como formulado por Gilles Deleuze. Sugerimos que a exploração desse debate possa atuar como um exercício de exterioridade ou de pensamento diferencial no jogo com o conhecimento e com o pensamento reflexivo presentes no campo educacional - seja no âmbito dos fazeres pedagógicos cotidianos da escola, seja no campo da produção da pesquisa educacional.This study aims to discuss the supposed virtuous constitution of education and knowledge originated from a certain cultural heritage of Western modernity.

Método: revisión integrativa de literatura, a partir de publicaciones científicas del área de la Salud, indexadas en las bases de datos SciELO ® , BVS, Scopus ® , CINAHL ® , PubMed ® , Web of Science ® . En el presente trabajo se analizaron los resultados obtenidos en el análisis de los resultados obtenidos en el estudio. Se empleó la palabra “Maffesoli”, teniendo como criterios de inclusión ser artículos completos, originales o de reflexión, que aplicaron el referencial teórico de Michel Maffesoli en el análisis o discusión de los datos, disponibles en los idiomas portugués, inglés, español y francés. Resultados : se seleccionaron 30 artículos, siendo gran parte de ellos con abordaje cualitativo y oriundos de la enfermería. Las nociones más presentes en los estudios fueron cotidianos, ética de la estética, tribu, potencia, juego doble, posmodernidad, los cuales abordaron lo cotidiano en sus diferentes escenarios de cuidado. Se expresa la importancia de estar atento a los aspectos subjetivos de lo cotidiano, considerando su complejidad, posibilitando nuevos y otros modos de estar-juntos. Conclusión : el pensamiento de Michel Maffesoli contribuye a la construcción del conocimiento en enfermería y salud, indicando caminos en las dimensiones del cuidado, en el campo académico y profesional, a partir del cotidiano de las personas, resignificando el cuidado que va más allá de la técnica, nos cambia la mirada y la dirección, para que podamos estar en sintonía con las diferentes situaciones del vivir y del convivir, abandonando el des-envolvimiento, para involucrarnos con un cuidado afectivo, el que toca, siendo, por lo tanto, efectivo.

Currently there are no brief, self-administered instruments for measuring the degree to which an adult with normal intelligence has the traits associated with the autistic spectrum. In this paper, we report on a new instrument to assess this: the Autism-Spectrum Quotient (AQ). Individuals score in the range 0-50. Four groups of subjects were assessed: Group 1: 58 adults with Asperger syndrome (AS) or high-functioning autism (HFA); Group 2: 174 randomly selected controls. Group 3: 840 students in Cambridge University; and Group 4: 16 winners of the UK Mathematics Olympiad. The adults with AS/HFA had a mean AQ score of 35.8 (SD = 6.5), significantly higher than Group 2 controls (M = 16.4, SD = 6.3). 80% of the adults with AS/HFA scored 32+, versus 2% of controls. Among the controls, men scored slightly but significantly higher than women. No women scored extremely highly (AQ score 34+) whereas 4% of men did so. Twice as many men (40%) as women (21%) scored at intermediate levels (AQ score 20+). Among the AS/HFA group, male and female scores did not differ significantly. The students in Cambridge University did not differ from the randomly selected control group, but scientists (including mathematicians) scored significantly higher than both humanities and social sciences students, confirming an earlier study that autistic conditions are associated with scientific skills. Within the sciences, mathematicians scored highest. This was replicated in Group 4, the Mathematics Olympiad winners scoring significantly higher than the male Cambridge humanities students. 6% of the student sample scored 32+ on the AQ. On interview, 11 out of 11 of these met three or more DSM-IV criteria for AS/HFA, and all were studying sciences/mathematics, and 7 of the 11 met threshold on these criteria. Test-retest and interrater reliability of the AQ was good. The AQ is thus a valuable instrument for rapidly quantifying where any given individual is situated on the continuum from autism to

At least 100 fish species are known to be present in the intertidal areas (estuaries, mudflats and salt marshes) of Mont Saint-Michel Bay. These and other comparable shallow marine coastal waters, such as estuaries and lagoons, play a nursery role for many fish species. However, in Europe little attention has been paid to the value of tidal salt marshes for fishes. Between March 1996 and April 1999, 120 tides were sampled in a tidal creek. A total of 31 species were caught. This community was largely dominated by mullets ( Liza ramada represent 87% of the total biomass) and sand gobies ( Pomatoschistus minutus and P. lozanoi represent 82% of the total numbers). These species and also Gasterosteus aculeatus , Syngnathus rostellatus, Dicentrarchus labrax, Mugil spp., Liza aurata and Sprattus sprattus were the most frequent species (>50% of monthly frequency of occurrence). In Europe, salt marshes and their creeks are flooded only during high spring tides. So, fishes only invade this environment during short immersion periods, and no species can be considered as marsh resident. But, the salt marsh was colonized by fish every time the tide reached the creek, and during the short time of flood, dominant fishes fed actively and exploited the high productivity. Nevertheless, this study shows that there is little interannual variation in the fish community and there are three ' seasons ' in the fish fauna of the marsh. Marine straggler and marine estuarine dependent species colonize marshes between spring (recruitment period in the bay) and autumn before returning into deeper adjacent waters. Estuarine fishes are present all year round with maximum abundances in the end of summer. The presence of fishes confirms that this kind of wetland plays an important trophic and nursery role for these species. Differences in densities and stages distribution of these species into Mont Saint-Michel systems (tidal mudflats, estuaries and tidal salt marshes) can reduce the trophic

To establish reference values for erythrocyte cholinesterase (EC 3.1.1.7) activity for the active working population of two regions of the department of Antioquia, Colombia, that are located at different altitudes above sea level. We took representative samples from populations of active working persons 18 to 59 years old from two regions in the department of Antioquia: (1) the Aburrá Valley (1 540 m above sea level) and (2) the near east of the department (2 150 m above sea level). We excluded workers who were using cholinesterase-inhibiting substances in their work or at home, those who had a disease that altered their cholinesterase levels, and those who said they were not in good health. We measured the erythrocyte cholinesterase activity using two methods: (1) the Michel method and (2) the EQM method (EQM Research, Cincinnati, Ohio, United States of America). We carried out the measurements with 827 people, 415 from the Aburrá Valley and 412 from the near east region. We compared proportions using the chi-square test and Fisher's exact test. We utilized the Student's t test for independent samples to compare two averages. To simultaneously compare three or more averages, analysis of variance was used, followed by the Newman-Keuls multiple-range test. When the variables were not normally distributed or when the variances were not homogeneous, Kruskal-Wallis nonparametric analysis of variance was used to compare the medians. Three computer software programs were used in the statistical analysis: SPSS 9.0, SGPlus 7.1, and Epi Info 6.04. In all the statistical tests the level of significance was set at P EQM method was 35.21 U/g hemoglobin (95% CI: 34.82 to 35.60).

Full Text Available El presente trabajo busca problematizar la supuesta constitución virtuosa entre educación y conocimiento, oriunda de cierta herencia cultural de la modernidad occidental. La problemática se apoya en la indagación difusa, aunque insistente, que se repite en el campo de la educación: “¿De qué se trata el acto de pensar, en educación, en la contemporaneidad?”. El tomar las condiciones actuales de pensamiento como un problema de investigación en educación, pone en duda la histórica articulación entre conocimiento y pensamiento reflexivo, lo que obliga a la confrontación de ciertas mezclas pedagógicas preciadas en el campo educativo moderno. Tal enfrentamiento se realiza a la luz de las reflexiones de los pensadores Michel Foucault y Friedrich Nietzsche, dada la relevancia estratégica de sus producciones, especialmente sobre el lenguaje, la producción de verdad y sus implicaciones en los modos de conocer y pensar. Se busca construir una crítica del lenguaje en dirección a una crítica del pensamiento en educación, en el centro de una problematización ético-política. En este trabajo, tal plataforma analítica se configura a partir de las discusiones de Michel Foucault, tanto en relación a la cuestión del pensamiento del afuera, como en relación al pensamiento de la diferencia, tal como fue formulado por Gilles Deleuze. Sugerimos que la explotación de ese debate, puede actuar como un ejercicio de exterioridad o de pensamiento diferencial en el juego con el conocimiento y con el pensamiento reflexivo presentes en el campo de la educación, sea en el ámbito de las tareas pedagógicas cotidianas en la escuela, o en el campo de la producción de la investigación en la educación.

Full Text Available Dieser Beitrag rekapituliert im Blick auf die Überlappungen von Macht, Souveränität und Herrschaft die soziale Morphologie der Foucaultschen Gesellschaftstheorie und betont dabei die Aktualität von Forschungen, die sich machtkritisch an den Dispositivbegriff anlehnen. Was ein Dispositiv ist, wird im Rekurs auf Deleuze und Agamben vor Augen geführt, um in der Figur der "schizophrenen Flucht" ein entscheidendes Moment der französischen Debatten auszumachen. Dabei ist der Panoptismus nach wie vor ein bemerkenswertes Modell, um historisch die innere Funktionsweise von Disziplinargesellschaften zu begreifen, die sich zu Kontrollgesellschaften gewandelt haben. Dem Homo digitalis steht angesichts von Big Data im Semiokapitalismus des 21. Jahrhunderts ein System wechselseitiger Kontrolle vor Augen, dem er sich lückenlos unterwerfen soll. Dem setzt sich nach wie vor die Figur der widerständigen Subjektivierung entgegen, wie sie Foucault in seinem Spätwerk entworfen hat. Auf allgemeinster Ebene hebt dieser Artikel hervor, dass wir auch heute noch ein politisches Modell vor Augen haben, dass der antiken Arena im Sinne einer politischen Heterotopie entspricht, in der es im Krieg um das nackte Überleben geht. Zusammenfassend wird Foucaults Kriegsparadigma über Michel de Certeaus Modellierung von Strategie und Taktik auf die Figur des Bürgerkriegs bezogen, um insgesamt zu betonen, dass dort wo Macht ist, immer auch Widerstand möglich ist. This article recaps the social morphology of Foucault’s theory of society in the light of power, sovereignty, and domination, emphasizing the actuality of research that is referring to the concept of apparatus.

The macrobenthic community of Mont Saint Michel Bay (English Channel, France) is mainly dominated by filter feeders, including cultivated species (oysters and mussels). An ecological model of the bay was developed, coupling a 2D hydro-sedimentary model and two biological models for primary production and filter-feeder filtration. The filter-feeder model includes three cultivated species ( Mytilus edulis, Crassostrea gigas and Ostrea edulis), one invasive species ( Crepidula fornicata) and eight wild native species ( Abra alba, Cerastoderma edule, Glycymeris glycymeris, Lanice conchilega, Macoma balthica, Paphia rhomboides, Sabellaria alveolata, andSpisula ovalis). For cultivated and invasive species, the production of biodeposits was computed to assess their role in restimulating primary production. Chlorophyll a concentrations appeared to be strongly controlled by the filter feeders. When the pressure of each benthic compartment on phytoplankton was estimated separately wild species and the invasive slipper limpet C.fornicata were shown to be key elements in the control of primary production. Conversely, the role of cultivated species, particularly oysters, was weaker. Feedback due to the mineralization of biodeposits also appears to be crucial to fully evaluate the role of filter feeders in primary production.

The present text examplifies by means of 60 citations from current textbooks for the study of physics the necessarity of a mathematically rigorous formulation of quantum mechanics. Well known statements of many physicists about quantum mechanics at their mathematical tool kit are commented in form of a dialogue und mathematical points of view. Supplemented are the representations by a selection of theorems of higher analysis relevant for quantum theory. The book applies to mathematicians and mathematically interested physicists or students with founded mathematical knowledge.
Ethical identification of the subject, and “techniques of the self” in the works of Michel Foucault

Full Text Available We are used to the image of an individual as getting into the social reality created before and without him; however, Michel Foucault questions the genealogy of the modern subject, and states that within a ready-made social reality an individual is not given even to himself. Foucault considers processes and practices of individual self-identification, and modes of subjectivation , i. e. the ways, by which an individual seeks and finds his place in an already and completely configured system of social relations. Foucault develops a specific conceptual tool - “techniques of the self” as sets of representations and practices, by which an individual changes oneself and integrates into some ethical systems (of knowledge, rules of behavior, power relations. “Techniques of the self” are purely social, they do not constitute any ethical identity; on the contrary, they provide a socially determined self-identification. Foucault’s “techniques of the self” let us conceptualize the coincidence of the seemingly anonymous processes of governing and individual self-definition; these techniques serve as indicators of individual ethical normalization. Identification of the “techniques of the self” in subjects’ actions helps to define the governing processes not as a violent submission, but as a basic state of the social interaction systems. In order to verify the heuristic potential of the “techniques of the self” concept, the author considers ancient and early Christian models of subjectivation, which Foucault opposed as two ethical models of subject’s access to the “truths”. With the ancient ethical “techniques of the self”, a subject is a full-fledged ethical agent; with the early Christian techniques, he is to accept one’s ontological inability to establish the righteousness based only on one’s personal experience. For example, such an opposition helps to explain differences between tutorship forms and self-control goals.
From Life to Existence: A Reconsideration of the Question of Intentionality in Michel Henry’s Ethics

Frédéric Seyler
2012-12-01
Full Text Available Michel Henry has renewed our understanding of life as immanent affectivity: life cannot be reduced to what can be made visible; it is – as immanent and as affectivity – radically invisible. However, if life (la vie is radically immanent, the living (le vivant has nonetheless to relate to the world: it has to exist. But, since existence requires and includes intentional components, human reality – being both living and existing – implies that immanence and intentionality be related to one another, even though they are conceived at the same time as radically distinct modes of appearing in Henry’s phenomenology of life. Following this line of thought, we are faced with at least two questions: First, what reality does immanent appearing have for us as existing and intentional beings? And second, from an ethical point of view, what does Henry’s opposition of “barbarism” and “second birth” mean in terms of existence? As will be shown, it follows from the standpoint of radical phenomenology itself that immanent affectivity has reality for us only insofar as it finds its expression or translation in the realm of the intentionally visible and that, with regard to ethics, both “barbarism” and its overcoming in “second birth” are effective only insofar as they are mediated through representations. Henry’s critique of representation and intentionality needs therefore to be revised, especially in the field of practical philosophy, where the essential role played by intentionality has to be acknowledged even by radical phenomenology.

Full Text Available Este artigo propõe-se a expor as reflexões de dois filósofos contemporâneos, quais sejam, Michel Foucault e Giorgio Agamben, de modo a promover um paralelo,ou mesmo uma analogia, entre duas noções que permeiam as obras dos respectivos autores. Estas noções consistem no que Foucault chamou de Racismo de Estado, e no que Agamben nomeou de Tanatopolítica. O contexto, e tambémo objeto, no qual se efetiva este intento é, em uma palavra, a política totalitária do Estado nazista.Ambos os autores compreendem os fenômenos totalitários a partir do ponto de vista da biopolítica, entretanto, ao tratar do Estado Nacional-socialista, Foucault identifica nele um paradoxo, sem, contudo desenvolver com maior profundidade a imbricação que ali se deu. Agamben, por sua vez, concebe semelhante paradoxo como pertencendo a uma forma de fazer política que já traz, desde a sua origem, os fundamentos que permitiram a emergência do fenômeno da forma como surgiu e que fora identificada pelos ditos autores, ou seja, trazendo em si tanto elementos antigos, como a glória e os ideais de sangue, quanto modernos, como a eugenia. A pesquisa bibliográfica que aqui se desenvolveu deu-se na leitura de, basicamente, três obras dos supraditos autores, quais sejam, Em defesa da sociedade, História da sexualidade I – A vontade de saber, de um lado (Foucault, e Homo sacer – O poder soberano e a vida nua I, de outro (Agamben.

-20th century born American scientists and among yet earlier European biologists and mathematicians. Results A group representing 1,925 American scientists showed the SCZ-resistance, GP2-coincident seasonality. However, this effect proved to be mostly due to biologists because biochemists, chemists, and physicists showed gradually less seasonality while mathematicians suggested an altogether artist-like, GP1-coincident seasonality. This intimation of a biologist-mathematician antithesis was pursued with an investigation of most major figures in the history of the two sciences from the 15th to the early-20th century. The two groups, numbering 576 mathematicians and 787 biologists, shared the same mean decade of birth, the 1780s, and essentially the same geographic origin in Western Europe. The mathematicians showed a very significant SCZ liability-like, GP1-coincident seasonality while the biologists showed an even more significant SCZ resistance-like, GP2-coincident seasonality. The latter effect was particularly strong among naturalists, anatomists and other groups representing biological “observationalism” as opposed to “experimentalism.” Discussion The findings are discussed in light of a) new evidence that the annual photoperiod is indeed alone responsible for both peaks of general births, with the GP1 and the GP2 being caused by maternal periconceptional exposure to, respectively, the summer-solstice sunlight maximum and the winter-solstice minimum, and b) an approach/withdrawal theory of lateralization of basic emotions where the left cerebral cortex would handle external stimuli eliciting complacent emotions towards external realities while the right cortex would handle internal stimuli eliciting disdain for those realities.

Às voltas com a História da Loucura: um percurso intelectual de Michel Foucault

Full Text Available Trata-se de compreender o projeto em História da Loucura na Idade Clássica [1961] como um élan à trajetória intelectual de Foucault, a qual problematiza a racionalidade das nossas relações com o Outro da cultura ocidental, isto é, com aquele que reside historicamente no não dito. Para tanto, torna-se necessário discutir as implicações sociais a partir da oposição entre o normal e o patológico, de modo a ressaltar uma questão fundamental em sua tese de 1961, a saber: de que maneira o louco, como representante de uma das experiências limite problematizadas por Foucault, passou a ser concebido como o Outro a ser recusado pela racionalidade ocidental. Desse modo, por meio de sua análise histórico- filosófica e da demonstração da crescente subordinação da loucura à razão – a partir da qual se torna possível a emergência da loucura e de suas redes de controle social –, trata-se de evidenciar de que modo o homem, como um objeto fictício de si, aparece como uma problematização já em seus primeiros escritos. Às voltas com as embrionárias reflexões e problematizações das (não relações que se tem com os saberes sujeitados da cultura ocidental, confere-se a contribuição de Michel Foucault à filosofia contemporânea, em sua tarefa crítica do pensamento que implica a arte de não ser governado pela verdade em sentido a-histórico.

This groundbreaking work features two essays written by the renowned mathematician Ilan Vardi. The first essay presents a thorough analysis of contrived problems suggested to "undesirable" applicants to the Department of Mathematics of Moscow University. His second essay gives an in-depth discussion of solutions to the Year 2000 International Mathematical Olympiad, with emphasis on the comparison of the olympiad problems to those given at the Moscow University entrance examinations. The second part of the book provides a historical background of a unique phenomenon in mathematics, which flourished in the 1970s-80s in the USSR. Specially designed math problems were used not to test students' ingenuity and creativity but, rather, as "killer problems," to deny access to higher education to "undesirable" applicants. The focus of this part is the 1980 essay, "Intellectual Genocide", written by B Kanevsky and V Senderov. It is being published for the first time.

Full Text Available During a school cycle of a year we implemented an experience of philosophy with children inspired by the thoughts of Michel Foucault. The objective of our meetings was to foster thought-experiments aimed at problematizing the world around us and thinking otherwise. In the course of our experience, the thoughts of children led to different questions and reflections which we have organized according to five categories in dialogue with the ideas of Foucault: 1 critical thinking, 2 self-criticism, 3 curiosity, 4 relationship with the truth and 5 thinking otherwise. In this paper, we share a part of the expressions that, from our perspective, show how children thought differently about the world that surrounds us, and their own thinking.

Among the mummies preserved in the Basilica of San Domenico Maggiore in Naples, there are the bodies of the wife and three children of Jean Antoine Michel Agar, Minister of Finance of Naple's Kingdom during the Monarchy of Joachim Murat (1808-1815). Between 1983 and 1987 paleopathological analyses were performed; in particular, X-ray examination allowed investigation of the health status of the Agar family members and reconstruction of the embalming processes used to preserve the bodies. In addition, an analysis of the historical and archival documents was carried out, to formulate hypotheses about the causes of death, demonstrating how these sources could become important instruments to obtain diagnoses and pathological histories.

Full Text Available This article explores one of the most incidental, and thus least studied, equivocations in Michel Foucault's work: his understan-ding of slavery in relation to his conceptualizations of power, domination, resistance and freedom. The article also considers the heuristic value of these equivocations for thinking about the regimes of the large slave plantations of the Americas. Does slavery describe a relation of power or a state of domination? What distinct analytical and ethical implications would this distinction have upon examining the problem of freedom under subjugation? Through a careful exegesis of two late instances in the work of the French thinker, "Subject and power" (1982 and "The ethics of care of the self as a practice of freedom" (1984, this article identifies the conceptual ambiguities that accompany his brief observations on slavery, and takes them as a starting point for highlighting a series of moments in which games of power during the period of slavery in the Americas show the limits that were intuited, yet not theorized, by Foucault; limits which are no other than extreme violence and death. This is exemplified through a discussion of certain paradoxes in the phenomena of the fugitive slaves (cimarronaje and of the aporias, that were manifested through the uses of the Christian pastoral as a means of subjection at the beginnings of the Cuban slave plantations during the 18th century - and in dialogue with their symbolization in art.

Na atualidade o uso dos documentos e de arquivos para criminalizar, encarcerar e segregar os desviantes sociais é uma prática cotidiana, e funciona pelo dispositivo de confissão nas adjacências do Poder Judiciário, operando as noções de risco e perigo, em termos de biopolítica. Já a escrita disciplinar aciona a constituição de casos e dossiês, por meio dos exames, das observações vigilantes e da sanção normalizadora, em uma microeconomia penal. é relevante criticar essas práticas e pensar campos de possibilidade de resistência a essas escritas de uma memória das infâmias na judicialização da vida.

All the data acquired with these technologies could be stored and managed together with other information in a Historical Building Information Model (HBIM). In this paper, it will be shown the case study of the San Michele in Acerboli's church, located in Santarcangelo di Romagna, Italy. This church, dated about the 6th century A.D., represents a high relevant Romanic building of the high Medieval period. The building presents an irregular square plan with a different length of the lateral brick walls and a consequential oblique one in correspondence of the apse. Nevertheless, the different lengths of the lateral brick walls are balanced thanks to the irregular spaces between the windows. Different changes occurred during the centuries, such as the closing of the seven main doors and the building of the bell tower, in the 11th century A.D., which is nowadays the main entrance of the church. An integrated survey was realized, covering the exterior and the interior. The final 3D model represents a valid support not only for documentation, but also to maintain and manage in an integrate approach the available knowledge of this Cultural Heritage site, developing a HBIM system in which all the mentioned historical, geometrical, material matters are collected.

Ensuring the accuracy of the dating method is of the utmost importance in order to achieve results which are pertinent enough to have archaeological significance. This paper deals with an archaeological building study of the first church built on the Mont-Saint-Michel (France) and improvements made to the TL-protocol in Bordeaux. The aim is to achieve precise dates for the material under analysis and therefore, a better understanding of the evolution of the building. For this study, 14 bricks have been sampled from eight different masonries and submitted for TL dating analysis. With the exception of one sample which appears to be non-contemporaneous to the others, the date results range from 900{+-}80 to 1020{+-}60 AD. The results were then averaged according to the two phases established by the archaeological building study. The first two stages of the primitive church both date from the 10th century.

This essay explores the practical significance of Michel Henry's "material phenomenology." Commencing with an exposition of his most basic philosophical intuition, i.e., his insight that transcendental affectivity is the primordial mode of revelation of our selfhood, the essay then brings to light how this intuition also establishes our relation to both the world and others. Animated by a radical form of the phenomenological reduction, Henry's material phenomenology brackets the exterior world in a bid to reach the concrete interior transcendental experience at the base of all exteriority. The essay argues that this "counter reduction," designed as a practical orientation to the world, suspends all traditional parameters of onto(theo)logical individuation in order to rethink subjectivity in terms of its transcendental corporeality, i.e., in terms of the invisible display of "affective flesh." The development of this "metaphysics of the individual" anchors his "practical philosophy" as he developed it-under shifting accents-throughout his oeuvre. In particular, the essay brings into focus Henry's reflections on modernity, the industry of mass culture and their "barbaric" movements. The essay briefly puts these cultural and political areas of Henry's of thinking into contact with his late "theological turn," i.e., his Christological account of Life and the (inter)subjective self-realization to which it gives rise.

Full Text Available En el contexto de su crítica a la fenomenomenología husserliana Michel Henry apela a la caracterización de los errores de la perspectiva hetero-afectiva remitiéndose a sus orígenes en la tradición sintetizados en los parámetros de la “gnosis griega” y su compromiso con la racionalidad entendida como comprensión de “objetos puestos a distancia”. La revisión de los alcances de esta categoría revela, sin embargo, que existen tratamientos en el pensamiento griego que apelan a la auto-afección y la inmanencia para dar cuenta de elementos que exceden la dimensión ek-stática. En este trabajo se revisa el planteo henryano para mostrar sus puntos de contacto con el estoicismo, especialmente a partir de la teoría de Hierocles a propósito de la oikeîosis. Este recorrido permitirá sugerir que entre ambos planteos existe una compatibilidad estructural que hace posible apelar a claves de interpretación similares para dar cuenta de la convivencia de mecanismos de explicación que apelan a lo auto-afectivo y lo hétero-afectivo en un conjunto coherente.

Most studies focusing on political movements only implicitly address the connection between biographical experiences and political attitudes. Moreover, a detailed understanding of these impacts often remains merely hypothetical. Biographical studies increasingly address the relationship between politics and biography through empirical and hermeneutic approaches. For his doctoral thesis, Dirk MICHEL conducts autobiographical narrative interviews with 20 Jewish Israelis. Based on their extraordinary biographical experiences, MICHEL categorized the interviewees into two groups—the "German Zionists" and the "German Holocaust survivors." He then conducts semi-structured interviews with each of the participants with the aim of analyzing their political attitudes. However, the conceptual categorization of the interviewees, the empirical investigation of the research question and the subsequent analysis all challenge the underpinning theoretical and methodological concepts of the study.

Full Text Available Michel Onfray e André Comte-Sponville são os dois mais famosos representantes do ateísmo filosófico francês contemporâneo, que continua uma tradição iniciada no século XVIII de negação irreligiosa da noção monoteísta de Deus. Embora compartilhando várias ideias, como o naturalismo e, obviamente, a rejeição do monoteísmo, suas propostas têm diferenças importantes. Onfray imputa à religião a maioria dos males enfrentados pela humanidade, recusando-se a fazer qualquer concessão à tradição religiosa monoteísta, e propondo uma filosofia libertária de tipo hedonista e materialista. Comte-Sponville vê aspectos positivos na religião no tocante à manutenção da unidade social e propõe uma espiritualidade mística ateia. O artigo faz uma breve apresentação de suas teses e formula críticas a ambas as propostas. Onfray está muito mais preocupado em convencer de uma proposta política do que em argumentar filosoficamente em favor de uma tese e Comte-Sponville não parece perceber as consequências auto-refutadoras do naturalismo, que também torna muito problemática a própria noção de moralidade. Palavras-chave: Michel Onfray; Comte-Sponville; ateísmo; neoateísmo; naturalismo. Abstract Michel Onfray and André Comte-Sponville are the most famous representatives of philosophical contemporary French atheism, which is a continuation of a tradition begun in the 18th Century of irreligious denying of the monotheistic notion of God. Although sharing many ideas, like naturalism and, obviously, the rejection of the monotheistic conception of God, their proposals show important distinctions. Onfray blames on religion most of evils faced by humanity, refusing to make any concession to monotheism, and proposing a libertarian, hedonistic, materialistic philosophy. Comte-Sponville sees positive aspects in religion regarding the keeping of social unity, and puts forward an atheistic spirituality. The article makes a brief

Full Text Available O artigo apresenta o resultado da pesquisa que abordou a investigação sobre as rupturas epistemológicas e o discurso sobre Deus na obra As palavras e as coisas, de Michel Foucault. Intitulada como "Deus, as palavras e as coisas", a pesquisa parcialmente apresentada aqui pretende ser uma colaboração para a análise do que se tem identificado como fenômeno do neo-ateísmo, um tema de grande relevância para a Filosofia da Religião nos dias atuais. Para compreendê-lo, apresentam-se, seguindo a perspectiva foucaultiana, os distintos matizes epistemológicos que sustentam a concepção sobre Deus. Em seus três momentos, o texto apresenta a episteme renascentista e o discurso de Deus, a episteme clássica e a idéia sobre Deus e, por fim, a episteme moderna, a morte de Deus e a morte do homem. Acredita-se que aquilo que se decide na contemporaneidade não seja necessariamente o acabamento do tempo da morte de Deus e a consequente morte do homem, fruto do modo moderno de compreender e tematizar o divino, o infinito, o absoluto ou o verdadeiro, mas uma clara disputa entre variadas perspectivas epistemológicas em suas concretizações científica, política, cultural e religiosa. Palavras-chaves: Michel Foucault, Filosofia da Religião, Epistemologia, Deus, Ateísmo. Abstract The article presents the results of research that investigate on epistemological ruptures and speaking about God in The Order of Things writhed by Michel Foucault. Entitled as "God, words and things," this research partially presented here is intended as collaboration for the analysis of what has been identified as phenomenon of neo-atheism, a topic very important for the Philosophy of Religion today. To understand it, we present, following the Foucaultian perspective, the different epistemological nuances underpinning conception of God. In her three moments, the text presents the Renaissance episteme and the God's discourse, the classical episteme and the idea of God

Nicolas Bourbaki, whose mathematical publications began to appear in the late 1930s and continued to be published through most of the twentieth century, was a direct product as well as a major force behind an important revolution that took place in the early decades of the twentieth century that completely changed Western culture.Pure mathematics, the area of Bourbaki's work, seems on the surface to be an abstract field of human study with no direct connection with the real world. In reality, however, it is closely intertwined with the general culture that surrounds it. Major developments in m

Full Text Available The secondary-school mathematics curriculum is narrow in scope and technical in character; this is quite different from the nature of the discipline itself. As a result, it offers little inspiration to both students and teachers, and provides students with poor preparation for university mathematics courses and indeed for life. Over the past century, recently more than ever, there have been calls for change, for a curriculum that is true to the subject of mathematics as the creation and study of patterns and structures. While there are hopeful responses to this at the elementary level, there is almost nothing at the secondary level. Ironically, it is felt that in order to prepare students for university calculus, the secondary curriculum simply has to be what it is. This is a special case of a myth that needs to be destroyed.

Mostra-se como este instituto, bem como a matemática ali produzida, serviram para a formação do campo científico de matemáticos no Brasil. Os principais resultados apontam para: a consolidação de linhas de pesquisa em Sistemas Dinâmicos, Álgebra, Análise Matemática, Geometria Diferencial e Estatística Matemática; a preocupação de formar pesquisadores para atender as demandas de quadros docentes das universidades brasileiras, produzir matemática e recrutar alunos "talentosos" visando garantir a formação de pesquisadores e a produção de matemática de qualidade. A rede de influências estabelecida pelos pesquisadores do instituto extrapolou seus limites, uma vez que os líderes ocupavam posições importantes nos órgãos de fomento e em outras instituições e sociedades intelectuais. O discurso dos pesquisadores revela a hierarquia acadêmica e o corporativismo reinante na instituição assim como seu prestígio na comunidade científica.This article presents the role played by the Institute of Pure and Applied Mathematics - Impa -, created in 1952 by the National Council for Scientific and Technological Development, in the education of researchers in mathematics in Brazil.

The aim of this article is to shed light on contemporary forensic psychiatric care through a philosophical examination of the empirical results from two lifeworld phenomenological studies from the perspective of patients and carers, by using the French philosopher Michel Foucault's historical-philosophical work. Both empirical studies were conducted in a forensic psychiatric setting. The essential results of the two empirical studies were reexamined in a phenomenological meaning analysis to form a new general structure in accordance with the methodological principles of Reflective Lifeworld Research. This general structure shows how the caring on the forensic psychiatric wards appears to be contradictory, in that it is characterized by an unreflective (non-)caring attitude and contributes to an inconsistent and insecure existence. The caring appears to have a corrective approach and thus lacks a clear caring structure, a basic caring approach that patients in forensic psychiatric services have a great need of. To gain a greater understanding of forensic psychiatric caring, the new empirical results were further examined in the light of Foucault's historical-philosophical work. The philosophical examination is presented in terms of the three meaning constituents: Caring as correction and discipline, The existence of power, and Structures and culture in care. The philosophical examination illustrates new meaning nuances of the corrective and disciplinary nature of forensic psychiatric care, its power, and how this is materialized in caring, and what this does to the patients. The examination reveals embedded difficulties in forensic psychiatric care and highlights a need to revisit the aim of such care.

This article discusses Michel Foucault's main writings on "madness and psychiatry" from his early works up to the 1970s. On the one hand, we reconstruct the overall theoretical and methodological development of his positions over the course of the different periods in his oeuvre. On the other hand, we also take a closer look at Foucault's philosophical considerations regarding the subjects of his investigations. After an initial introduction of our conceptual approach, we draw on the most recent research on Foucault to show to what extent the phenomenological description of the topic at hand and the historical-critical perspective that are reflected in his early writings of 1954 (the Introduction to Binswanger's Dream and Existence and Mental Illness and Personality) laid the ground for his later work. Moving on to Foucault's work during the 1960s, we look at the core features and methodological bases of his 1961 classic Folie et déraison (History of Madness). His propositions regarding the "absence of madness" in modernity are conceptualized as an inherently contradictory attempt to liberate the topic under study from the common assumptions at that time. We then situate his 1973/74 lectures on Psychiatric Power in the context of his shift towards analyzing the dynamics of power and highlight the renewed shift of focus in his statements on the "productivity" of madness as an effect of power. Finally, we sum up our critique by taking into account the history of the reception of Foucault's writings and ask about their potential significance for the contemporary philosophy and history of psychiatry.

Full Text Available O objetivo deste artigo é oferecer ferramentas conceituais que possam ajudar na reflexão acerca da questão das biopolíticas da saúde a partir da obra de Michel Foucault, Agnes Heller e Hannah Arendt. Para Foucault, desde o século XVIII, a vida biológica e a saúde da nação tornaram-se alvos fundamentais de um poder sobre a vida que enfatizava especialmente as noções de sexualidade, raça e degenerescência, cujo objetivo era a otimização da qualidade biológica das populações. Para Arendt, esse movimento de politização da vida é profundamente antipolítico. A vida passa a ocupar o vazio deixado pela decomposição do âmbito público. No caso de Agnes Heller, o antipolitismo do discurso biopolítico se manifesta na procura constante de legitimação quase científica. O pensamento de raça, gênero, saúde é um pensamento científico imitado que substitui a opinião pela verdade. Se a política é o campo do confronto das opiniões, do diálogo, da iniciativa, do novo, da espontaneidade e da ação em liberdade, o pensamento biopolítico legitimado cientificamente é o espaço da verdade, da certeza, da necessidade, do determinismo e da causalidade, no qual o diálogo é substituído por uma política da autoclausura, de amigos e inimigos, e a pluralidade de opiniões é reduzida a uma única opinião politicamente correta.

Full Text Available O objetivo deste artigo é, partindo das ponderações de Pierre Bourdieu acerca da importância do estudo das condições sociais da circulação internacional de ideias, fazer uma sociologia histórica da circulação e da recepção do livro Sociologia dos partidos políticos, de Robert Michels. Toma-se como foco a passagem de Michels e de seu livro pelos Estados Unidos, procurando mostrar como consolidou-se a partir daí uma forma de leitura do texto e uma representação do autor que é hoje predominante e que está na base da sua celebração e da sua consagração como um clássico da Ciência Política. Para tanto, faz-se uma comparação sistemática de diferentes edições e traduções do livro, bem como de resenhas que dele foram produzidas, procurando identificar distintas leituras feitas ao longo do tempo, associando-as com elementos da trajetória biográfica do autor, bem como com a história das Ciências Sociais nos Estados Unidos e, em particular, com a história da Ciência Política nesse país. De um autor pessimista em relação à democracia, ou mesmo com um viés antidemocrático, associado ao fascismo, Michels foi sendo visto no pós-Guerra como um pensador realista e suas teses como base para a formulação de uma noção de democracia identificada com o pluralismo liberal.

Quels avantages a-t-il pu présenter aux yeux des deux auteurs d’Ennemis publics, le philosophe Bernard-Henri Lévy et le romancier Michel Houellebecq ? La prise en charge de vérités autobiographiques et la notion de « littérature d’aveu » occupent une place centrale parmi ces avantages : elles nous permettront de problématiser la question de la lettre, « laboratoire de valeurs ». Le questionnement éthique auquel ils se livrent les incite ainsi à s’interroger sur leurs conceptions de la nature du sujet, de la responsabilité, de l’engagement et de l’action. On analysera, chemin faisant, quelques tropes spécifiques de leurs « visions du monde » antithétiques et on tentera de rendre compte du fait que leurs débats permettent de partager une aventure heuristique qui défige leurs images publiques respectives, objets de critiques virulentes de la part de nombreux journalistes et de commentateurs. L’évocation polémique de ces critiques joue certes un rôle important dans Ennemis publics, mais elle ne fera pas l’objet de cette contribution. On tentera ici de démontrer que cette correspondance met en œuvre et concrétise quelques-uns des concepts et des questionnements majeurs inhérents à la réflexion philosophique sur l’éthique.The epistolary genre is not the only discursive framework in which the justification of axiological beliefs can be observed and analyzed.

No momento da colheita, foi avaliado o desempenho agronômico da variedade Rebo. Em São Joaquim, o ciclo da variedade Rebo é mais longo, o acúmulo térmico é menor, a precipitação pluviométrica e a radiação solar global acumulada são maiores do que em San Michele All’Adige. As temperaturas mais baixas e a menor insolação durante a floração-mudança de cor das bagas são os principais fatores climáticos relacionados com as menores produtividades das plantas. Em São Joaquim, as baixas temperaturas e as elevadas taxas de radiação solar global na maturação contribuem de maneira positiva na formação dos compostos fenólicos, mas dificultam a degradação dos ácidos da variedade Rebo.

The article focuses not only on the similarities, but also on the divergences between the concept of prospective architecture defined in France and VAL’s projects from the 1970s. The article will try to reveal parallels between the VAL’s definition of architecture as a result of a game and a way to anticipate the new society, and the approach of architects and groups active in France as the Utopia, or the Internationale Situationniste. In conclusion, the text will emphasize the specificity of VAL’s projects, inseparably linked to the context of Czechoslovakia during the period of Normalization, and stress its heterogeneous character linking them more closely to the postmodern architecture.

Os procedimentos metodológicos de investigação foram divididos em dois momentos. Primeiro, foram pesquisados os artigos publicados nos últimos dez anos nos anais de dois dos mais representativos encontros científicos da academia de administração no Brasil: o Encontro Nacional da ANPAD (EnANPAD, encontro anual, e o Encontro de Estudos Organizacionais (EnEO, que ocorre de dois em dois anos. A pesquisa foi feita nos artigos que referenciavam Michel Foucault no título ou no escopo do resumo. No que diz respeito ao número de ocorrências encontradas, os resultados obtidos totalizaram 41 artigos. Em um segundo momento, após a identificação dos artigos, estes foram lidos e analisados de forma a identificar como Michel Foucault é categorizado por cada um dos pesquisadores em questão. Os resultados obtidos na pesquisa levam a crer que as questões epistemológicas ainda não fazem parte do corpo de preocupações de grande parte dos pesquisadores brasileiros na área de administração. Tal ausência apresenta-se, ao mesmo tempo, significativa e preocupante. Significativa, porque mostra que os pesquisadores brasileiros não estão preocupados com o contexto teórico de produção e disseminação das idéias, incorporando-as como verdades em suas pesquisas de forma descontextualizada e acrítica. E preocupante, uma vez que a luta por poder no campo das idéias não significa apenas um embate em torno dos melhores postos acadêmicos, posições institucionais e governamentais de financiamento ou um lugar de destaque nos comitês editoriais dos periódicos mais influentes. O perigo reside em uma dimensão complementar e inerente a essa

Full Text Available Resumo: Este trabalho tem o objetivo de analisar a relação entre a Missão dos Padres Matemáticos, expedição organizada pela Coroa portuguesa na primeira metade do século XVIII para realizar estudos sobre os territórios portugueses na América, e o desenvolvimento de uma cultura ilustrada em Portugal, pois, segundo nosso entendimento, a “missão” se relaciona às transformações culturais vividas em Portugal naquele período. Nesta análise partimos do pressuposto teórico de que as ações humanas, apesar de expressarem uma individualidade, correspondem a um determinado contexto social, político, econômico e cultural. Isso significa que o pensamento e comportamento humano associam-se a uma “configuração” – conceito aplicado por Norbert Elias, na obra A sociedade de corte (2001, para estudar a sociedade da corte francesa entre os séculos XVII e XVIII.Palavras-chave: Ilustração – Fronteiras Americanas – Mineração – Padres Matemáticos. Abstract: This paper is intended to analyze the relationship between the Mission of the Mathematicians Priest expedition organized by the Portuguese crown in the first half of the eighteenth century to conduct studies on the Portuguese territories in America, and the development of an illustrated culture in Portugal. According to our understanding, the "mission" is connected to cultural transformations in Portugal at that time. In this analysis we set of theory premise that human actions, although expressing individuality, correspond to a particular, political, economic and cultural context. This means that human thought and behavior associated to a "configuration" - concept applied by Norbert Elias, The society in the work of cutting (2001, to study the society of the French court between the seventeenth and eighteenth centuries.Keywords: Illustration – American Borders – Mining – Mathematical Priests.

Full Text Available Questo articolo cerca di esplorare il rapporto tra parrēsia ed exemplum negli ultimi Corsi al Collège de France di Michel Foucault. A partire da L’ermeneutica del soggetto, viene analizzato il campo semantico e pratico relativo alla direzione di coscienza stoica ed epicurea, in cui Foucault oppone la parrēsia all’adulazione e alla retorica per collocarla invece all’interno di un’importante serie di concetti: la paradosis (la trasmissione dei discorsi di verità, il kairos (il momento giusto, la circostanza opportuna e l’exemplum definito come «il cuore della parrēsia» poiché esso assicura l’adæquatio tra il soggetto di enunciazione e il soggetto di comportamento che si conforma alla verità espressa dal primo. Successivamente, viene posta l’attenzione sul legame tra parrēsia ed exemplum nell’ultimo Corso, Il coraggio della verità, per mettere in evidenza un’importante riconfigurazione all’interno della parrēsia cinica, in cui l’esempio appare come una categoria etica basata sulla permanenza e sull’identità a sé. Pertanto, esso si rivela inadeguato per questo regime aleturgico della parrēsia cinica, che invece consiste in un atteggiamento etico sperimentale, una mise à l’épreuve cui sottomettere la vita per arrivare a una trasformazione politica del mondo attraverso una continua e scandalosa provocazione degli altri, in grado di mettere in discussione la percezione di norme culturali e di abitudini consolidate.
A new interpretation of the symbolic codes for the Henon Map. II
International Nuclear Information System (INIS)
Yamaguchi, Yoshihiro; Tanikawa, Kiyotaka
2011-01-01
A certain region in the phase space for the area- and orientation-preserving Heon map is filled with the resonance chains. Taking this fact into account, the concept of block word has been introduced in the preceding paper. The concept of resonance chains in the symbol plane is also introduced and the marquetry structure of the symbol plane is investigated. If the orbit in the horseshoe travels over the resonance chains, the orbit is represented by a block word sequence. There are four purposes discussed in this paper. The first purpose is to introduce a new concept of parity to characterize the periodic orbits. The second is to study the detailed structure of the symbol plane. The third is to clarify the behaviors of symmetric periodic orbits in the resonance chain and determine their block word sequences. The fourth is to propose an improved construction method to make a braid for a non-Birkhoff periodic orbit in a resonance chain. (author)
On the design of henon and logistic map-based random number generator
Magfirawaty; Suryadi, M. T.; Ramli, Kalamullah
2017-10-01
The key sequence is one of the main elements in the cryptosystem. True Random Number Generators (TRNG) method is one of the approaches to generating the key sequence. The randomness source of the TRNG divided into three main groups, i.e. electrical noise based, jitter based and chaos based. The chaos based utilizes a non-linear dynamic system (continuous time or discrete time) as an entropy source. In this study, a new design of TRNG based on discrete time chaotic system is proposed, which is then simulated in LabVIEW. The principle of the design consists of combining 2D and 1D chaotic systems. A mathematical model is implemented for numerical simulations. We used comparator process as a harvester method to obtain the series of random bits. Without any post processing, the proposed design generated random bit sequence with high entropy value and passed all NIST 800.22 statistical tests.
Michel Foucault e a teoria do poder
ALBUQUERQUE, JOSÉ AUGUSTO GUILHON
1995-01-01
Mais do que a teoria do poder, Foucault propõe regras ou cautelas metodológicas. Diferentemente das concepções correntes, Foucault pretende explicar o poder sem o rei como sua fonte e natureza. Depois de comparar diferentes concepções correntes de poder, mostrando sua dependência da noção de um soberano, define-se o poder em Foucault como uma relação assimétrica que institui a autoridade e a obediência, e não como um objeto preexistente em um soberano, que o usa para dominar seus súditos.

Full Text Available "Si j'étais prétentieux, je donnerais comme titre général à ce que je fais : généalogie de la morale." Dietro questa affermazione, rilasciata nel contesto colloquiale di un'intervista, è possibile scorgere il segno di una confessione intellettuale e il compendio di un pensiero. In primo luogo, allusivamente, rinvia alla figura di Nietzsche e alla traccia indelebile che il suo pensiero ha lasciato nella filosofia e nella ricerca di Foucault. In secondo luogo, autorizza a osservare nella riflessione foucaultiana la filigrana di quella genealogia che il presente lavoro si propone di affrontare come stile d'interrogazione filosofica.

Full Text Available RESUMOEstuda-se contribuições teórico-metodológicas de Foucault, realçando seu uso de elementos metodológicos clássicos. O artigo se organiza em três eixos analíticos: o exame de fragmentos da obra desse autor, especialmente de seus Cursos; aproximações de sua perspectiva com a literatura contemporânea sobre pesquisa qualitativa; e a análise de textos nos quais ele explicita suas escolhas metodológicas. Acentua-se sua opção de estudar problemas a partir de "suas formas mais singulares e concretas". Explora-se o delineamento, concomitantemente clássico e inovador, de sua pesquisa derradeira da genealogia do sujeito moderno analisando as razões de suas escolhas metodológicas. Considera-se que a construção de problemas de pesquisa relevantes, associada ao trabalho detalhado e preciso, contribuiu para o impacto incisivo de sua obra.

O pensador Michel Maffesoli, sociólogo francês estudioso do imaginário e do cotidiano, mostra como o espírito pós-moderno de diluição, desconstrução e quebra de paradigmas pervade todas as dimensões da vida contemporânea, inclusive formatando o jeito de crer e a forma de entender o religioso. A partir daí, os estudos do religioso – especialmente Teologia, Ciências da Religião e Ensino Religioso – reelaboram seus conceitos modernos, reestruturando seu campo a partir de novas categorias de análise da sociedade propostas por Maffesoli: Sociedade Neotribal, Associação pelo Desejo-de-estar-juntos, Processos de indentificação, Homeopatia do mal, Efeito de composição, entre outros.Palavras-chave: Michel Maffesoli; estudos de religião; pós-modernidade; neotribalismo; sociologia, imaginário religioso.

The organizations, the power and Michel Foucault / Las organizaciones, el poder y Michel Foucault

Full Text Available Max Weber alleged that power and domination coexist in organizations; and that power is the ability to attain certain resources (economic, force, knowledge, etc.. When an organization is operating -using these resources, e.g., power-, and requires that orders are observed, domination must be applied under the logic of the administrative framework. This assumption attributes, as expected, a very reactionary role to the administration. Foucault rephrases the dilemma using the microphysics of power, relieving the administration of any suspicion of conservatism.

Full Text Available The aim of the present article is to reveal the essential connection of MichelFoucault’s critical attitude regarding social relationships with the formation of thepostmodern ethos of making out of the human life an artwork. It will be shown thatthe main object of Foucault’s critique are the relations of power and knowledge inthe Christian priesthood and their modern transformation in nonreligious institutions.From this point of view, mainly based on the philosophy of Friedrich Nietzsche,the Christian ethics occur to be an accumulation of techniques of disciplinizationand normalization. This attitude towards Christianity and modernity leads to thepostmodern ethos of making out of life an artwork. This notion is mainly based onthe antique Greek and Roman philosophy, where instead of obeying to universalethical principles the human being struggled to be his own master. Therefore thepostmodern existence tries to be beyond all traditional boundaries, which resultsin the danger of neglecting the historical fact, that Christianity was and still is animportant institution of the Western Civilization.

Full Text Available Healthcare remote devices are recognized as a promising technology for treating health related issues. Among them are the wireless Implantable Medical Devices (IMDs: These electronic devices are manufactured to treat, monitor, support or replace defected vital organs while being implanted in the human body. Thus, they play a critical role in healing and even saving lives. Current IMDs research trends concentrate on their medical reliability. However, deploying wireless technology in such applications without considering security measures may offer adversaries an easy way to compromise them. With the aim to secure these devices, we explore a new scheme that creates symmetric encryption keys to encrypt the wireless communication portion. We will rely on chaotic systems to obtain a synchronized Pseudo-Random key. The latter will be generated separately in the system in such a way that avoids a wireless key exchange, thus protecting patients from the key theft. Once the key is defined, a simple encryption system that we propose in this paper will be used. We analyze the performance of this system from a cryptographic point of view to ensure that it offers a better safety and protection for patients.

Approximating Perfection considers the background behind mechanics as well as the mathematical ideas that play key roles in mechanical applications. Concentrating on the models of applied mechanics, the book engages the reader in the types of nuts-and-bolts considerations that are normally avoided in formal engineering courses: how and why models remain imperfect, and the factors that motivated their development. The opening chapter reviews and reconsiders the basics of c
André-Louis Cholesky mathematician, topographer and army officer
Brezinski, Claude
2014-01-01
Outside the professional circles of topography and applied mathematics, the life and work of André-Louis Cholesky (1875–1918) are still relatively unknown to the scientific community. This new book appreciably widens the exposure of his remarkable personal achievements in topography and mathematics to a much larger international audience. Cholesky is also interesting to historians because he is a perfect representative of the "scientists engineers" that, since the early 19th century, had issued from the French scientific high schools. Because they had received a high level of mathematical education, they were able to innovate in their practice of engineering. In the case of Cholesky, this resulted in original contributions in artillery, topography, numerical analysis and graphical calculation. In addition, the book places his education and works within the history of several European countries through the 17th to 19th centuries. The book begins with Cholesky's biography, followed by his family’s hi...
Perturbative algebraic quantum field theory an introduction for mathematicians
Rejzner, Kasia
2016-01-01
Perturbative Algebraic Quantum Field Theory (pAQFT), the subject of this book, is a complete and mathematically rigorous treatment of perturbative quantum field theory (pQFT) that doesn’t require the use of divergent quantities. We discuss in detail the examples of scalar fields and gauge theories and generalize them to QFT on curved spacetimes. pQFT models describe a wide range of physical phenomena and have remarkable agreement with experimental results. Despite this success, the theory suffers from many conceptual problems. pAQFT is a good candidate to solve many, if not all of these conceptual problems. Chapters 1-3 provide some background in mathematics and physics. Chapter 4 concerns classical theory of the scalar field, which is subsequently quantized in chapters 5 and 6. Chapter 7 covers gauge theory and chapter 8 discusses QFT on curved spacetimes and effective quantum gravity. The book aims to be accessible researchers and graduate students interested in the mathematical foundations of pQFT are th...

Autocrate negli encomi imperiali di Michele Psello (1018-1081

Lauritzen Frederick
2012-01-01
Full Text Available In the imperial encomia of Michael Psellos (1018-1081? the terms αυτοκράτωρ and βασιλευς are not equivalent and the former appears quite rarely. One may deduce that αυτοκράτωρ is not a generic term but has a specific meaning which indicates that the emperor has delegated his executive power to a minister. The term βασιλευς, instead, simply indicates an emperor. The term αυτοκράτωρ was used mainly when the μεσάζωυ was Constantine Leichoudes (1042-1050. Therefore the term αυτοκράτωρ actually indicates not only the delegation of executive power to a μεσάζωυ but also that a certain cultural current was present at court to which belonged Psellos. Moreover, the term αυτοκράτωρ is employed as an adjective with moral connotations. Such an understanding of the meaning of αυτοκράτωρ implies that the encomia were written for the person of the emperor but also included the culture of his μεσάζωυ.

The aim of this paper is to present the design of a hydraulic microturbine (MTH), which may be installed in areas where supplies are not available for electric power transmission lines, but possessing hydroelectric. MTH's role is to convert hydraulic energy into mechanical work, is coupled to an electric generator, whose function is to convert the mechanical energy into electrical energy. The turbine generator set will produce more electric power the greater the hydroelectric of the area. In southern Mexico, we have great hydroelectric potential, as the case of the states of Veracruz, Chiapas and Oaxaca, which have small causes of rivers where the MTH could be installed and put into operation. [Spanish] El objetivo de este articulo es presentar el diseno de una microturbina hidraulica (MTH), la cual podra ser instalada en zonas donde no se cuente con suministro de energia electrica por medio de lineas de transmision, pero que posean aprovechamientos hidroelectricos. La funcion de la MTH es convertir la energia hidraulica en trabajo mecanico, estara acoplada a un generador electrico, cuya funcion es convertir dicha energia mecanica en energia electrica. El conjunto turbina generador producira mas potencia electrica mientras mayor sea el aprovechamiento hidroelectrico de la zona. En el sur de Mexico contamos con un gran potencial hidroelectrico, como el caso de los estados de Veracruz, Chiapas y Oaxaca, que cuentan con pequenos causes de rios donde las MTH podrian ser instaladas y puestas en operacion.

Optimal transport for applied mathematicians calculus of variations, PDEs, and modeling
Santambrogio, Filippo
2015-01-01
This monograph presents a rigorous mathematical introduction to optimal transport as a variational problem, its use in modeling various phenomena, and its connections with partial differential equations. Its main goal is to provide the reader with the techniques necessary to understand the current research in optimal transport and the tools which are most useful for its applications. Full proofs are used to illustrate mathematical concepts and each chapter includes a section that discusses applications of optimal transport to various areas, such as economics, finance, potential games, image processing and fluid dynamics. Several topics are covered that have never been previously in books on this subject, such as the Knothe transport, the properties of functionals on measures, the Dacorogna-Moser flow, the formulation through minimal flows with prescribed divergence formulation, the case of the supremal cost, and the most classical numerical methods. Graduate students and researchers in both pure and appl...

Finding zero a mathematician's odyssey to uncover the origins of numbers
Aczel, Amir D
2015-01-01
The invention of numerals is perhaps the greatest abstraction the human mind has ever created. Virtually everything in our lives is digital, numerical, or quantified. The story of how and where we got these numerals, which we so depend on, has for thousands of years been shrouded in mystery. Finding Zero is an adventure filled saga of Amir Aczel’s lifelong obsession: to find the original sources of our numerals. Aczel has doggedly crisscrossed the ancient world, scouring dusty, moldy texts, cross examining so-called scholars who offered wildly differing sets of facts, and ultimately penetrating deep into a Cambodian jungle to find a definitive proof. Here, he takes the reader along for the ride. The history begins with the early Babylonian cuneiform numbers, followed by the later Greek and Roman letter numerals. Then Aczel asks the key question: where do the numbers we use today, the so-called Hindu-Arabic numerals, come from? It is this search that leads him to explore uncharted territory, to go on a gran...

Daniel Walter Brown
2010-10-01
Full Text Available This brief forum contribution reflects upon some historical factors in the formation of nineteenth century science and of the literature and science discipline that has since arisen to study its literary receptions. Noting the preponderance of studies focusing upon forms of scientific developmentalism, principally Darwinian biology, and of novels and other prose, and more broadly, on literary figures, rather than the writings of scientists, the paper introduces some poetry on science by scientists. It concentrates principally on those working and writing in the fields of physics and mathematics, areas that have been neglected in literature and science studies.

[The unbroken power of psychiatry as seen through the eyes of Michel Foucault].
Kraan, H F
2006-01-01
Is the psychiatrist still a powerfulforce in society? Foucault, a 'historical philosopher' concerned with power relations, would have answered this question in the affirmative. Possibly, however, the psychiatrist's sovereign power is weaker than it was a century ago because some of the psychiatrist's tasks have been re-allocated. Some have been assigned to the growing number of specialist groups in the mental health service, others have been put in the hands of 'health managers' who form part of our country's growing bureaucracy and put a financial and economic burden on our health service. Nevertheless, the procedural power of psychiatrist has not been weakened; psychiatrists are able to deprive patients of their freedom, pronounce them unfit for work and reduce punishments and sentences for serious crime on the grounds of diminished responsibility. This procedural power is accentuated by the increasing influence of psychology in society. The power of psychiatric knowledge has shifted from an archaic to a demonstrative discourse about truth which is rooted in evidence-based medicine and which enhances the power of psychiatrists still further. This may also mean that the 19th century concept of hysteria is perpetuated in psychiatric practice in all kinds of modern clinical forms.

Michel Foucault and the genealogy as a criticism of the present
Directory of Open Access Journals (Sweden)
Selvino José Assmann
2007-04-01
Full Text Available The main goal of this paper is to analyze the criticism to modernity that is in Foucault’s genealogy. First we discuss Focault’s analysis of Kant’s article on Aufklärung and Baudelaire’s concept of dandy. So, we focus gave emphasis the “truth analytic” and its ontextualization made by Foucault of the social role of an intellectual in the light of the great changes in knowledge and in the practices of power in the last decades. To conclude, we suggest that, by studying the Aufklärung investigating the excess of modern racionality, Foucault tries to reassess the possibilities of freedom practices, sustaining the criticism exercise as philosophical ethos. This is needed to redefine the governability and ethical and political commitments made by the agents in different social places.
FINAL REPORT "Extreme non-linear optics of plasmas" Pierre Michel (16-LW-022)
Energy Technology Data Exchange (ETDEWEB)
Michel, Pierre [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
2017-11-03
Large laser facilities such as the National Ignition Facility (NIF) are typically limited in performance and physical scale (and thus cost) by optics damage. In this LDRD, we investigated a radically new way to manipulate light at extreme powers and energies, where “traditional” (crystal-based) optical elements are replaced by a medium that is already “broken” and thus does not suffer from optics damage: a plasma. Our method consisted in applying multiple lasers into plasmas to imprint refractive micro-structures with optical properties designed to be similar to those of crystals or dielectric structures used in optics. In particular, we focused our efforts on two elements used to manipulate the polarization of lasers (i.e. the orientation of the light’s electric field vector): i) a polarizer, which only lets a given polarization direction pass and blocks the others, and ii) a “Pockels cell”, which can “rotate” the polarization direction or convert it from linear to elliptical or circular. These two elements are essential building blocks in almost all laser systems – for example, they can be combined to design optical gates. Here, we introduced the new concepts of a “plasma polarizer” and a “plasma Pockels cell”. Both concepts were demonstrated in proof-of-principle laboratory experiments in this LDRD. We also demonstrated that such laser-plasma systems could be used to provide full control of the refractive index of plasmas as well as their dispersion (variation of the index vs. the light wavelength), which constituted the basis for a final experiment aimed at demonstrating the feasibility of “slow light” in plasmas, i.e. the capability to slow down a light pulse almost to a full stop.

She assesses the influence the Crii-Rad had on official communication on nuclear issues. Then, she addresses the issue of nuclear wastes, the choice of sites, the opinion of the population which could be favourable only because the people make their living from this activity. She outlines the role of the military nuclear sector and that it is an opaque one. She states that nuclear is obsolete, that the waste issue has not been solved, and that nuclear fission still creates new radioactive materials and thus raises problems. She outlines that it will always be more difficult to build a nuclear power plant, that the concept of public interest is not relevant for nuclear energy. She finally briefly evokes alternate solutions such as gas which indeed produces CO_2 but much less than transports

Introduction To Control Of Oscillations And Chaos
International Nuclear Information System (INIS)
Fradkov, A. L.; Pogromsky, A. Yu.
1998-01-01
This book gives an exposition of the exciting field of control of oscillatory and chaotic systems, which has numerous potential applications in mechanics, laser and chemical technologies, communications, biology and medicine, economics, ecology, etc. A novelty of the book is its systematic application of modern nonlinear and adaptive control theory to the new class of problems. The proposed control design methods are based on the concepts of Lyapunov functions, Poincare maps, speed-gradient and gradient algorithms. The conditions which ensure such control goals as an excitation or suppression of oscillations, synchronization and transformation from chaotic mode to the periodic one or vice versa, are established. The performance and robustness of control systems under disturbances and uncertainties are evaluated.The described methods and algorithms are illustrated by a number of examples, including classical models of oscillatory and chaotic systems: coupled pendula, brusselator, Lorenz, Van dar Pol, Duffing, Henon and Chua systems. Practical examples from different fields of science and technology such as communications, growth of thin films, synchronization of chaotic generators based on tunnel diodes, stabilization of swings in power systems, increasing predictability of business-cycles are also presented. The book includes many results on nonlinear and adaptive control published previously in Russian and therefore were not known to the West. Researchers, teachers and graduate students in the fields of electrical and mechanical engineering, physics, chemistry, biology, economics will find this book most useful. Applied mathematicians and control engineers from various fields of technology dealing with complex oscillatory systems will also benefit from it

The “Monty Hall Dilemma” (MHD) is a well known probability puzzle in which a player tries to guess which of three doors conceals a desirable prize. After an initial choice is made, one of the remaining doors is opened, revealing no prize. The player is then given the option of staying with their initial guess or switching to the other unopened door. Most people opt to stay with their initial guess, despite the fact that switching doubles the probability of winning. A series of experiments investigated whether pigeons (Columba livia), like most humans, would fail to maximize their expected winnings in a version of the MHD. Birds completed multiple trials of a standard MHD, with the three response keys in an operant chamber serving as the three doors and access to mixed grain as the prize. Across experiments, the probability of gaining reinforcement for switching and staying was manipulated, and birds adjusted their probability of switching and staying to approximate the optimal strategy. Replication of the procedure with human participants showed that humans failed to adopt optimal strategies, even with extensive training. PMID:20175592

The linear-quadratic (LQ) model is the only mathematical formula linking cellular survival and radiation dose that is sufficiently consensual to help radiation oncologists and radiobiologists in describing the radiation-induced events. However, this formula proposed in the 1970s and α and β parameters on which it is based remained without relevant biological meaning. From a collection of cutaneous fibroblasts with different radiosensitivity, built over 12 years by more than 50 French radiation oncologists, we recently pointed out that the ATM protein, major actor of the radiation response, diffuses from the cytoplasm to the nucleus after irradiation. The evidence of this nuclear shuttling of ATM allowed us to provide a biological interpretation of the LQ model in its mathematical features, validated by a hundred of radiosensitive cases. A mechanistic explanation of the radiosensitivity of syndromes caused by the mutation of cytoplasmic proteins and of the hypersensitivity to low-dose phenomenon has been proposed, as well. In this review, we present our resolution of the LQ model in the most didactic way. Copyright © 2016 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS.

Many educational researchers are concerned with the apparent poor performance of different racial and ethnic groups in the fields of science, engineering, and mathematics in the United States. Despite improvements in the performance of African Americans, Hispanic Americans, and Native Americans in these areas over the past decade, these groups are still less likely to enroll in advanced math and science courses or score at or above the proficient level in mathematics. Furthermore, these groups continue to be underrepresented in the nation's technical and scientific workforce. The purpose of this study was to identify the critical elements related to the success of African Americans in science, engineering, and mathematics. Specifically, this study was designed to answer the following questions as they pertained to African American graduate students: What factors were perceived to have contributed to the students' initial interest in science, engineering, or mathematics? What factors were perceived to have contributed to the students' decisions to continue their studies in their specific areas of interest? What factors, associated with the K--12 schooling experience, were perceived to have contributed to the students' success in science, engineering, or mathematics? The data for the study were acquired from interviews with 32 African American students (16 males and 16 females) who were engaged in graduate work in science, engineering, or mathematics. Four major themes emerged from the analysis of the interview data. The first was that all students were involved in experiences that allowed a significant level of participation in science, engineering, and mathematics. Second, all of the students experienced some form of positive personal intervention by another person. Third, all students possessed perceptions of these fields that involved some sort of positive outcome. Finally, all of the of the students believed they possessed intrinsic qualities that qualified and prepared them for their involvement with science, engineering, and mathematics. These four themes exhibited themselves in different ways during the course of the students' lives. As a result, the discussion of the results of the study was divided among the three developmental periods: the interest-building phase, the knowledge-acquisition phase, and the careerbuilding phase. The study's findings provide valuable information to schools, educators, policy makers, and researchers on how to prepare effectively all children for a science and technology driven society, and for some, induction into tomorrow's scientific community.

Para o alcance do mesmo, optamos por fazer uma análise de documentos, ou seja, de três dissertações de mestrado e uma tese de doutorado, sendo que os dados foram coletados a partir de quatro questões norteadoras vinculadas ao objetivo geral do estudo: quais os componentes do processo de viver as relações familiares no cotidiano? Quais as dificuldades que as famílias encontram na convivência cotidiana com o doente mental? Quais as formas de manejos apresentadas pelas famílias em diferentes situações no convívio cotidiano com o alcoolista? Qual a percepção do ser e viver saudável da mulher no seu cotidiano? Na análise dos dados, buscamos convergências e divergências que nos permitissem uma melhor compreensão dos aspectos em estudo.

What difficulties do families have to cope with mentally handicapped individuals? How do families handle different situations in daily living with alcohol addicted individuals? What was the women’s perception regarding being and living healthy in their daily routine? When analyzing the data, we looked for convergences and divergences which provided better understanding of the aspects under study.

Full Text Available French geographer, Michael Rochefort (1927-2015, built his career as an important name in the planning of his country. Part of this was because of his lengthy participation in the Comissariat General du Plan, a governmental agency in France, whose objectives are quite similar to the Brazilian Institute of Geography and Statistics (IBGE, an institution which would be one of the nodal points in Rochefort’s relationship with Brazil for over five decades. This article analyses this relationship in the 1960s, when IBGE, together with the methodologies proposed by Rochefort and François Perroux, developed important subsidy policies for planning. Despite the theoretical limitations in IBGE’s work in the 1960s, the institute’s work turned out to be of great importance for the political territories in at least the two decades following. Michael Rochefort exemplifies, through his work, the undeniable contribution of French geography to Brazilian geography during the years marked by the period of planning and national developmentalism in Brazil.

The article presents the results of a doctoral dissertation defended at the Universidad de Salamanca, based on Foucault's final decade of writings. If Foucault's goal in writing The History of Sexuality was to fashion a genealogy of ethics, my goal in analyzing this book, along with his other writings, is to demonstrate his last contribution to the history of medicine. He moves from a conception of power over others towards a conception of power over oneself, an exclusive terrain of ancient Greek morality. As a thinker who tries to understand today's problems by going to their roots, Foucault develops less a history than a philosophy of history. Considered an anti-humanist, he leaves us with a portrait of a wholly ethical-humanistic medicine.

Full Text Available Montaigne traza una conciencia de la individualidad en un punto medio que evita tanto la deploración del yo del luteranismo como la absolutización de la razón del cartesianismo. Somos un punto en el tiempo y el espacio, pequeñez que desestima cualquier divinización del juicio personal y, de paso, explica la pluralidad del mundo. Pequeñez que alienta tanto el trato con la interioridad como el interés por los otros. Montaigne fosters a sort of awareness of the individual, which is halfway in between the Lutheran denial of the self and the Carthesian absolutization of reason. We are just a tiny dot in time and space; a fact that prevents us from deifying our personal judgment and, in so doing, explains the plurality of the world. And this smallness encourages us both to care of our own intimacy, and to worry about the others.

Full Text Available This article agrees with Meretz (2014 that the peer producing cooperatives which are proposed by Bauwens & Kostakis (2014 will become parts and parcels of the capitalist economy. Further, it argues that the so called Peer Production Licenses (PPL, originally designed by Dmitry Kleiner (2010, which is the basis of their proposal is a rent seeking instrument. Contra Bauwens & Kostakis, it argues that, from the perspectives of both reform and revolution, GPL is profoundly anti-capitalist. The article critiques Meretz`s understanding of exchange and reciprocity, on the one hand, and his underestimation of GPL`s communist aspect, on the other. On the positive side, the article, explicating the communist nature of GPL-oriented peer production, speculates about the general contours of a society where peer production is the dominant mode of production. The technological basis of this society, the article suggests, will be digital copying and automation. Spatially, it will be based on localities that transcend the current division between the city and country, synthesising agriculture with industrial, affective and symbolic production. The rise of a globally unified revolutionary social struggle which adopts peer production as its platform is indispensible for the transformation of capitalism into such a society. A global network of revolutionary peer producing cooperatives which break with market and reduce their relations to it to an absolutely unavoidable necessary minimum can be a significant component of this social struggle. The building of these revolutionary cooperatives requires a massive exodus from the city to the country.

Full Text Available Scepticism is a doctrine which holds the possibilities of knowledge to be limited. There are many types of scepticism (practical /theoretical, partial/total, moderate/ radical, etc. Scepticism as a philosophy began with Pyrrho of Elis (365–275 BC. The rediscovery of the sceptical texts during Renaissance affected the developmentof modern sceptical currents. In France philosophical statements of scepticism were offered by Michel de Montaigne (1533–1592. Blaise Pascal (1623–1662 great French mathematician, scientist, inventor an religious thinker was familiar with Montaigne sceptical ideas. Pascal refers to Montaigne as the most illustrious defender of scepticism. Blaise Pascal point of view is original. Whenever he insiststhat no proof is ever certain but simultaneously he adds that scepticism is untenable because we have reasons to believe.

Full Text Available Faced with the growth of nationalism and racism in Occident, this essay aims to provide some theoretical tools to think ‘historically’ racism. To this end, I propose a study of the reflections of Foucault and Balibar about this issue. Their positions, although different, converge in approaching racism as a problem connected with the construction of identity, in which the stakes are, according to Balibar, the political hegemony of a class in the national context, and, according to Foucault, the establishment of power relationships in the social context. In the years in which Foucault studies the genesis of racism, he’s also interested to the political role of knowledge as tool both of domination and struggle. So, according to his re-enacting, biological racism takes form in opposition to the idea of revolution to present the domination of a part of society as something founded in their dangerous nature. Balibar assumes that after the decolonization a new racism has taken shape, in which the category of race has been replaced by that of immigration. According to the new racism, cultures can’t live in peace if they mix each other and the only antidote to racism is closing nation’s borders. In this regard, Balibar shows that the same creation of nation needs the division of society in races: racism appears so closely connected with nationalism but also with ideology of class, that presents differences of class as insuperable anthropological and moral differences.

Full Text Available Como reconocimiento a los aportes de Foucault a la investigación histórica, este análisis relaciona historia y crítica con la comprensión del funcionamiento de la subjetividad moderna y contemporánea, con el fin de descifrar la forma como este autor revela las matrices de subjetivación que nos constituyen como sujetos modernos. La analítica de sus obras permite entender la coherencia de su objetivo al relacionar el trabajo histórico con la comprensión minuciosa del presente, y así ubicarse en una línea de trabajo establecida por Kant. Lo cual implica entender relaciones problemáticas, como las que establecemos entre su comprensión del mundo greco-romano y la búsqueda de formas históricas de vida que permitan construir posiciones de sujeto frente a las situaciones contemporáneas de los mundos neoliberales, orientadas a darle un sentido al discurso histórico asociándolo a la búsqueda de una fundamentación ética de la existencia.

Full Text Available The purpose of this writing is to propose a frame of view, a form as the eternal world element, that is compatible with paradox within the history of ideas, modern discovery as they confront one another. Under special consideration are problems of representation of phenomena, life, the cosmos as the rational facility of mind confronts the physical/perceptual, and itself. Current topics in pursuit are near as diverse and numbered as are the possibilities for a world composed strictly of uniqueness able to fill infinite space; it is assumed that not all of the paths chosen in contemporary pursuits will produce coherent determinations in an appropriate frame able to accommodate a world of nominals in motion, containing motion, and is commensurate with basic physical law and the propagation of form, change from within. Intended as a potential guiding post for the aim of reason seeking to select, define and capture topics, chosen as special examples are the works of logistician/mathematician Lewis Carroll as he presents a paradox of actuality verses the reality of perception in Alice in Wonderland, the theory of relativity of Albert Einstein as he fails to elaborate a mathematics to communicate an inertial frame of reference, and the reconstruction ideas of Jacques Derrida as he refers for contrast with the scientific world view constructed of dualisms, monisms that are conceived to have no opposites. Supporting discussion is evolved from the works of Bertrand Russell, Erwin Schrodinger, Jurgen Habermas, Bronislaw Malinowski, Michel Foucault.

We study numerically the dynamics of a network made of two coupled one-dimensional ensembles of discrete-time systems. The first ensemble is represented by a ring of nonlocally coupled Henon maps and the second one by a ring of nonlocally coupled Lozi maps. We find that the network of coupled ensembles can realize all the spatio-temporal structures which are observed both in the Henon map ensemble and in the Lozi map ensemble while uncoupled. Moreover, we reveal a new type of spatiotemporal structure, a solitary state chimera, in the considered network. We also establish and describe the effect of mutual synchronization of various complex spatiotemporal patterns in the system of two coupled ensembles of Henon and Lozi maps.

Tensor Calculus and Analytical Dynamics provides a concise, comprehensive, and readable introduction to classical tensor calculus - in both holonomic and nonholonomic coordinates - as well as to its principal applications to the Lagrangean dynamics of discrete systems under positional or velocity constraints. The thrust of the book focuses on formal structure and basic geometrical/physical ideas underlying most general equations of motion of mechanical systems under linear velocity constraints.

We study the transition from coherence (complete synchronization) to incoherence (spatio-temporal chaos) in ensembles of nonlocally coupled chaotic maps with nonhyperbolic and hyperbolic attractors. As basic models of a partial element we use the Henon map and the Lozi map. We show that the transition to incoherence in a ring of coupled Henon maps occurs through the appearance of phase and amplitude chimera states. An ensemble of coupled Lozi maps demonstrates the coherence-incoherence transition via solitary states and no chimera states are observed in this case.

Full Text Available Analisa-se o termo medicalização nos estudos de Illich e Foucault, com vistas a oferecer ferramentas conceituais para o estudo dos movimentos contestatórios à medicalização. Illich aborda a hipertrofia da medicalização na modernidade, ressaltando o efeito de redução da autonomia dos sujeitos, sobretudo pelo fato de as instituições médicas assumirem a responsabilidade de cuidar da dor, transformando seu significado íntimo e pessoal em um problema técnico. Foucault aborda a medicalização a partir da noção de biopoder, e, quando trabalha a noção de governamentalidade, abre espaço para a análise das formas de resistência dos indivíduos ao exercício do poder. Ambos os trabalhos, que têm como preocupação propor formas de exercício da liberdade - apesar de Foucault o fazer de forma mais detalhada e diversificada - parecem apropriados para se pensar o processo atual de desmedicalização ou recusa do diagnóstico médico por parte de seus portadores ou familiares.

Ordinary differential equations having a first integral may be solved numerically using one of several methods, with the integral preserved to machine accuracy. One such method is the discrete gradient method. It is shown here that the order of the method can be bootstrapped repeatedly to higher orders of accuracy. The method is illustrated using the Henon-Heiles system. (letter to the editor)

Design of High-Security USB Flash Drives Based on Chaos Authentication

Full Text Available This paper aims to propose a novel design of high-security USB flash drives with the chaos authentication. A chaos authentication approach with the non-linear encryption and decryption function design is newly proposed and realized based on the controller design of chaos synchronization. To complete the design of high-security USB flash drives, first, we introduce six parameters into the original Henon map to adjust and obtain richer chaotic state responses. Then a discrete sliding mode scheme is proposed to solve the synchronization problem of discrete hyperchaotic Henon maps. The proposed sliding mode controller can ensure the synchronization of the master-slave Henon maps. The selection of the switching surface and the existence of the sliding motion are also addressed. Finally, the obtained results are applied to design a new high-security USB flash drive with chaos authentication. We built discrete hyperchaotic Henon maps in the smartphone (master and microcontroller (slave, respectively. The Bluetooth module is used to communicate between the master and the slave to achieve chaos synchronization such that the same random and dynamical chaos signal can be simultaneously obtained at both the USB flash drive and smartphone, and pass the chaos authentication. When users need to access data in the flash drive, they can easily enable the encryption APP in the smartphone (master for chaos authentication. After completing the chaos synchronization and authentication, the ARM-based microcontroller allows the computer to access the data in the high-security USB flash drive.

This report concerns two proposals of law which have a common concern: warranting the rights of the miners and retired miners after the disappearing of the national association of retired miners management (ANGR), the members of which are the three companies of Charbonnages de France group (French national coal board), today undergoing a progressive shut-down. In this report, it is proposed to merge the contributions of both proposals with the creation of a new national agency for the warranty of the perenniality of miners' rights. It proposes also some necessary adaptations of the structures of Charbonnages de France group and some dispositions aiming at modernizing the French mining law and ensuring the exploitation of solid mineral fuels after the disappearing of the group.

Do dynamical systems follow Benford's law?

Data compiled from a variety of sources follow Benford's law, which gives a monotonically decreasing distribution of the first digit (1 through 9). We examine the frequency of the first digit of the coordinates of the trajectories generated by some common dynamical systems. One-dimensional cellular automata fulfill the expectation that the frequency of the first digit is uniform. The molecular dynamics of fluids, on the other hand, provides trajectories that follow Benford's law. Finally, three chaotic systems are considered: Lorenz, Henon, and Roessler. The Lorenz system generates trajectories that follow Benford's law. The Henon system generates trajectories that resemble neither the uniform distribution nor Benford's law. Finally, the Roessler system generates trajectories that follow the uniform distribution for some parameters choices, and Benford's law for others. (c) 2000 American Institute of Physics
Measuring transient chaos in nonlinear one- and two-dimensional maps
International Nuclear Information System (INIS)
Buszko, Katarzyna; Stefanski, Krzysztof
2006-01-01
In this paper, we present results of numerical experiments on chaotic transients in families of the logistic and Henon maps. The duration of chaotic transients (the rambling time) for logistic maps estimated according to a rigorous criterion shows monotonic regularities with respect to both the period and the number of periodic window in a series of a given period. Due to inapplicability of this criterion to multidimensional maps, a more universal, though approximate, criterion is systematically studied on the family of logistic maps to optimize a choice of the free parameter value. The same approximate criterion is used to estimate rambling time for a number of periodic windows for the family of Henon maps. The dependence of the rambling time on the width of periodic windows is tested

In this work we analyse nonlocally coupled networks of identical chaotic oscillators. We study both time-discrete and time-continuous systems (Henon map, Lozi map, Lorenz system). We hypothesize that chimera states, in which spatial domains of coherent (synchronous) and incoherent (desynchronized) dynamics coexist, can be obtained only in networks of chaotic non-hyperbolic systems and cannot be found in networks of hyperbolic systems. This hypothesis is supported by numerical simulations for hyperbolic and non-hyperbolic cases.

2009-01-01
The function projective synchronization of discrete-time chaotic systems is presented. Based on backstepping design with three controllers, a systematic, concrete and automatic scheme is developed to investigate function projective synchronization (FPS) of discrete-time chaotic systems with uncertain parameters. With the aid of symbolic-numeric computation, we use the proposed scheme to illustrate FPS between two identical 3D Henon-like maps with uncertain parameters. Numeric simulations are used to verify the effectiveness of our scheme. (general)
A Hybrid Chaotic and Number Theoretic Approach for Securing DICOM Images
Directory of Open Access Journals (Sweden)
Jeyamala Chandrasekaran
2017-01-01
Full Text Available The advancements in telecommunication and networking technologies have led to the increased popularity and widespread usage of telemedicine. Telemedicine involves storage and exchange of large volume of medical records for remote diagnosis and improved health care services. Images in medical records are characterized by huge volume, high redundancy, and strong correlation among adjacent pixels. This research work proposes a novel idea of integrating number theoretic approach with Henon map for secure and efficient encryption. Modular exponentiation of the primitive roots of the chosen prime in the range of its residual set is employed in the generation of two-dimensional array of keys. The key matrix is permuted and chaotically controlled by Henon map to decide the encryption keys for every pixel of DICOM image. The proposed system is highly secure because of the randomness introduced due to the application of modular exponentiation key generation and application of Henon maps for permutation of keys. Experiments have been conducted to analyze key space, key sensitivity, avalanche effect, correlation distribution, entropy, and histograms. The corresponding results confirm the strength of the proposed design towards statistical and differential crypt analysis. The computational requirements for encryption/decryption have been reduced significantly owing to the reduced number of computations in the process of encryption/decryption.

In the main part of this report, the author first proposes an overview of the energy policy as a shared competence and priority of the Junker Commission: this competence is shared between the European Union and member States, and a Union of energy is a political priority at the service of economic growth and of commitments for the climate. The author also proposes an overview of the main legal measures present in the fourth energy package: energy efficiency and energetic performance of buildings, development of renewable energies, organisation of the electric power market and security of supply, governance of the Union of energy and sector regulation. He discusses the position of the French Senate Commission for economic affairs: a general agreement (notably about energy efficiency, renewable energies, central role awarded to consumers, industrial and social support for energy transition) with some reservations on some proposed action modalities (notably with respect to the principles of subsidiarity, proportionality, sovereignty and responsibility of member states).

This classic textbook by two mathematicians from the USSR's prestigious Kharkov Mathematics Institute introduces linear operators in Hilbert space, and presents in detail the geometry of Hilbert space and the spectral theory of unitary and self-adjoint operators. It is directed to students at graduate and advanced undergraduate levels, but because of the exceptional clarity of its theoretical presentation and the inclusion of results obtained by Soviet mathematicians, it should prove invaluable for every mathematician and physicist. 1961, 1963 edition.
Maccone, C.
SETI searches are, by definition, the extraction of very weak radio signals out of the cosmic background noise. When SETI was born in 1959, it was "natural" to attempt this extraction by the only detection algorithm well known at the time: the Fourier Transform (FT). In fact: 1) SETI radio astronomers had adopted the viewpoint that a candidate ET signal would necessarily be a sinusoidal carrier, i.e. a very narrow-band signal. Over such a narrow band, the background noise is necessarily white. And so, the basic assumption behind the FT that the background noise must be white was "perfectly matched" to SETI for the next fifty years! 2) In addition, the Americans, J. W. Cooley and J. W. Tukey discovered in April 1965 that all the FT computations could be speeded up to N*ln(N) (rather than N2) (N is the number of numbers to be processed) by their own Fast Fourier Transform (FFT). Then, SETI radio astronomers all over the world gladly and unquestioningly adopted the new FFT forever. In 1983, however, the French SETI radio astronomer, François Biraud, dared to challenge this view (ref. [6]). He argued that we only can make guesses about ET's telecommunication systems, and that the shifting trend on Earth was from narrow-band to wide-band telecommunications. Thus, a new transform, other than the FFT, was needed that could detect signals over both narrow and wide bands, regardless of the colored noise distribution over any finite bandwidth. Such a transform had actually been pointed out as early as 1946 by the Finn mathematician, Kari Karhunen, and the French mathematician, Michel Loève, and is thus named KLT for them. In conclusion, François Biraud suggested to "look for the unknown in SETI" by adopting the KLT rather than the FFT. The same ideas were reached independently by this author also, and starting 1987, he too was "preaching the KLT": first at the SETI Institute, then (since 1990) at the Italian CNR (now called INAF) SETI facilities at Medicina, near Bologna
