Die Beschädigung von etwa 300 Exemplaren des Tagebuchs des deutsch-jüdischen Mädchens Anne Frank in Japan scheint die wissenschaftliche Ansicht, in Japan gäbe es kaum Antisemitismus, in Frage zu stellen. Insgesamt soll es 2014 ähnliche Vorfälle in 38 Bibliotheken allein in Tokio gegeben haben. Ein Zeichen für die Rückkehr des Rechtsradikalismus in Japan? Da viele Japaner sich ein Bild vom Holocaust anhand dieses einen Buches machen, stellt sich auch die Frage: Was für ein Bild von der Schriftstellerin und vom Holocaust vermittelt die japanische Übersetzung? Studien zeigen, wie Übersetzungen ein Original verzerren können. Inwieweit ist das japanischsprachige Bild von Anne Frank eine Verzerrung? Dieser Vortrag vergleicht Das Tagebuch in seiner ersten japanischen Übersetzung (1952) mit der ihr zugrunde liegenden englischen Übersetzung (1952): Inwieweit wurden Anne Frank und ihre Geschichte japanisiert? Was hat man weggelassen, was hinzugefügt? Die Geschichte des japanischen Antisemitismus und Berichte von jüdischjapanischen Beziehungen während des Zweiten Weltkriegs bilden den Hintergrund.

There has long been a need for a simulation environment rich enough to support the development of an AI system sufficiently knowledgeable about physical causality to pass certain tests of Psychometric Artificial Intelligence (PAI) and Psychometric Artificial General Intelligence (PAGI). In this article, we present a simulation environment, PAGI World, which is: cross-platform (as it can be run on all major operating systems); open-source (and thus completely free of charge to use); able to work with AI systems written in almost any programming language; as agnostic as possible regarding which AI approach is used; and easy to set up and get started with. It is our hope that PAGI World will give rise to AI systems that develop truly rich knowledge and representation about how to interact with the world, and will allow AI researchers to test their already-developed systems without the additional overhead of developing a simulation environment of their own. After clarifying both PAI and PAGI, we summarize arguments that there is great need for a simulation environment like PAGI World. We present multiple examples of already-available PAI and PAGI tasks in PAGI World, covering a wide range of research areas of interest to the general-purpose AI community.

John Licato et al.Pyridoxiz Acid Excretion During Low Vitamin BH-6 Intake, Total Fasting, and Bed Rest

Vitamin B-6 metabolism in 10 volunteers during 21 d of total fasting was compared with results from 10 men consuming a diet low only in vitamin B-6 (1.76 mumol/d) and with men consuming a normal diet during bed rest. At the end of the fast mean plasma concentrations of vitamin B-6 metabolites and urinary excretion of 4-pyridoxic acid tended to be higher in the fasting subjects than in the low-vitamin B-6 group. The fasting subjects lost approximately 10% of their total vitamin B-6 pool and approximately 13% of their body weight. The low-vitamin B-6 group lost only approximately 4% of their vitamin B-6 pool. Compared with baseline, urinary excretion of pyridoxic acid was significantly increased during 17 wk of bed rest. There was no increase in pyridoxic acid excretion during a second 15-d bed rest study. These data suggest the possibility of complex interactions between diet and muscle metabolism that may influence indexes that are frequently used to assess vitamin B-6 status.

Stephen P. Coburn et al.Universal Upper and Lower Bounds on Energy of Spherical Designs
http://opus.ipfw.edu/math_facpubs/169
http://opus.ipfw.edu/math_facpubs/169Wed, 17 Aug 2016 07:47:31 PDT
Linear programming (polynomial) techniques are used to obtain lower and upper bounds for the potential energy of spherical designs. This approach gives unified bounds that are valid for a large class of potential functions. Our lower bounds are optimal for absolutely monotone potentials in the sense that for the linear programming technique they cannot be improved by using polynomials of the same or lower degree. When additional information about the structure (upper and lower bounds for the inner products) of the designs is known, improvements on the bounds are obtained. Furthermore, we provide ‘test functions’ for determining when the linear programming lower bounds for energy can be improved utilizing higher degree polynomials. We also provide some asymptotic results for these energy bounds.

We derive and investigate lower bounds for the potential energy of finite spherical point sets (spherical codes). Our bounds are optimal in the following sense – they cannot be improved by employing polynomials of the same or lower degrees in the Delsarte-Yudin method. However, improvements are sometimes possible and we provide a necessary and sufficient condition for the existence of such better bounds. All our bounds can be obtained in a unified manner that does not depend on the potential function, provided the potential is given by an absolutely monotone function of the inner product between pairs of points, and this is the reason for us to call them universal. We also establish a criterion for a given code of dimension n and cardinality N not to be LP-universally optimal, e.g. we show that two codes conjectured by Ballinger et al to be universally optimal are not LP-universally optimal.

In recent years, the numerical range lifting problem has been solved for operators on , , and on certain Orlicz spaces . Specifically, given an operator , there exists a compact perturbation such that the numerical range of equals the essential numerical range of . This result has also been established for essentially Hermitian operators on . In the present paper, the authors establish this result for all operators on .

In this paper, we investigate the prediction (or best approximation) operator from a uniformly convex real Orlicz space to a subset of σ-lattice measurable functions. In particular, a counterexample to the monotoncity property, which holds in Lp spaces, is given. Also, a sufficient condition for monotonicity to hold is given. Finally, nested σ-lattices, as occur in isotonic regression, are considered.

It is well known that T(r,f) is differentiable at least for r>r0. We show that, in fact, T(r,f) is differentiable for all but at most one value of r, and if T(r,f) fails to have a derivative for some value of r, then f is a constant times a quotient of finite Blaschke products.

We construct a candidate for the natural best L_{1}-approximation to an integrable function, ƒ, by elements of an L_{1}-closed convex proximinal set. If ƒ is a Lebesgue integrable function on [0, 1] and the approximating set is the set of all nondecreasing functions, we show that our construction gives an extension of the known natural best L_{1}-approximation operator from ∪_{p > 1}L_{p} to L_{1}. In the course of doing this, we also complete the characterization, given in (Huotari, Meyerowitz, and Sheard, J. Approx. Theory47(1986), 85–91) of the set of all best L_{1}-approximations. Finally, in the case of isotonic approximation to a function of several variables, we extend a previous result concerning the almost everywhere convergence of the best L_{p}-approximations, p > 1, to the natural best L_{1}-approximation.

http://opus.ipfw.edu/math_facpubs/192
http://opus.ipfw.edu/math_facpubs/192Wed, 17 Aug 2016 07:38:41 PDT
We define the property “E-cylindrical,” which relates to a subset of ^{m} certain directed cylinders. We investigate some of the consequences of this definition, showing, for example, that polyhedral convex sets and smooth, rotund convex bodies are E-cylindrical. Suppose X is a finite set, F is the set of all real-valued functions on X, fϵF, andK ⊂F is closed, convex, and E-cylindrical. For 1 < p < ∞, let f_{p} be the best l_{p}-approximation to f by elements of K. We show that lim_{p → ∞}f_{p} exists. We give an example to show that {f_{p}} may fail to converge if X is countably infinite. We discuss the relationship between discrete (l_{p}) and continuous (L_{p}) approximation.
