AbstractModelling other agents is a challenging topic in artificial intelligence research particularly when a subject agent needs to optimise its own decisions by predicting their behaviours under uncertainty. Existing research often leads to a monotonic set of behaviours for other agents so that a subject agent can not cope with unexpected decisions from the other agents. It requires creative ideas about developing diversity of behaviours so as to improve the subject agent’s decision quality. In this paper, we resort to evolutionary computation approaches to generate a new set of behaviours for other agents and solve the complicated agents’ behaviour search and evaluation issues. The new approach starts with the initial behaviours that are ascribed to the other agents and expands the behaviours by using a number of genetic operators in the behaviour evolution. This is the first time that evolutionary techniques are used to modelling other agents in a general multiagent decision framework. We examine the new methods in two well-studied problem domains and provide experimental results in support.

So contended Edmund Burke in the House of Commons, during a May 1770 speech that ridiculed the government's American policy. It was not the first time Burke raised the subject of this 1543 statute. He had asked—rhetorically—during debates two weeks before, “The Act of Henry VIII. Did you mean to execute that?” He then answered his own question, the scorn beneath it probably apparent to all. “You showed your ill will to America, at the same time you dared not execute it.” Burke hoped that by shaming the ministry he might be able to push through a set of resolutions condemning its policies, which could open the way for a new approach to imperial management. He failed, but that did not mean he had been wrong about the futility of threatening to resurrect an old statute to intimidate protesting Americans.

The aim of  the  paper  is  to  show  the  conditions  of  subjectivity constitution in terms of dialogue and the figure of the Other. The analytical and hermeneutical approach I hold is the foundation of interdisciplinary attempt to describe  possible  concepts  of  shared  relation of the terms: consciousness, subjectivity and identity. The three appear to be recognized only in the ethical situation. It requires taking responsibility for the Other, for giving him the identity which mirrors one’s subjectivity. In this way the subject learns the limits and chances for gaining self-knowledge. The paper also presents a new approach towards redefining the definition of subjectivity, which includes artificially and medically enhanced entities.

1,1-Diphenylindan was treated with one molecule of bromine. It yielded a monobromide, which was condensed with methyl and ethyl alcohols, piperidine, p-toluidine, and aniline. With aqueous solutions of potassium carbonate, the monobromide directly gave rise to 1,1-diphenylindene and small quantities of diphenylindanyl ether.The condensation of the monobromide with sodium ethyl malonate yielded ethyl 1,1-diphenyl-3-indanmalonate from which 1,1-diphenyl-3-indanmalonic and 1-1-diphenyl-3-indanacetic acids were prepared. A few derivatives of these acids were also obtained.To establish the constitution of 1,1-diphenyl-3-indanacetic acid and, hence, that of the monobromide and of the other compounds, this acid was prepared directly from 3,3-diphenyl-1-indanone by a Reformatsky reaction with ethyl bromoacetate.The method of preparation of 1,1-diphenylindan has been improved, 1,1-diphenylindene has been obtained by new methods, and the following compounds are described, as far as the authors are aware, for the first time: 3-bromo-1,1-diphenylindan, 3-methoxy-1,1-diphenylindan, 3-ethoxy-1,1-diphenylindan, 3-N-piperidyl-1,1-diphenylindan, N-phenyl-1,1-diphenyl-3-indanamine, N-p-tolyl-1,1-diphenyl-3-indanamine, ethyl 1,1-diphenyl-3-indanmalonate, 1,1-diphenyl-3-indanmalonic acid, 1,1-diphenyl-3-indanmalonic acid p-nitrobenzyl ester, silver salt of 1,1-diphenyl-3-indanmalonic acid, 1,1-diphenyl-3-indanacetic acid, 1,1-diphenyl-3-indanacetic acid p-nitrobenzyl ester, silver salt of 1,1-diphenyl-3-indanacetic acid, 1,1-diphenyl-3-indanacetanilide, 1,1-diphenyl-3-indanacetamide, 1,1-diphenyl-3-indanacetonitrile, 1,1-diphenyl-3-indanethylamine hydrochloride, ethyl 3-hydroxy-1,1-diphenyl-3-indanacetate, ethyl 1,1-diphenyl-3-indeneacetate, 1,1-diphenyl-3-indeneacetic acid, silver salt of 1,1-diphenyl-3-indeneacetic acid, 1,1-diphenyl-3-indeneacetic acid p-nitrobenzyl ester, ethyl 1,1-diphenyl-3-indanacetate.

Aeschylus (also spelled Aischylos or Aiskhylos) was born c. 525/4 bce to an aristocratic family in Eleusis, a town in western Attica, part of the territory controlled by Athens. He was one of the earliest tragic poets. He first entered a tragic competition c. 499 (dramatic competitions were introduced in the 530s bce ) and won first prize for the first time in 484. In the 470s he visited Sicily, where he was the guest of Hieron of Syracuse. He also died in Sicily (at Gela) in 456/5, during a visit after the production of his Oresteia in Athens in 458. During his lifetime and after his death he was celebrated as one of the finest, if not the finest Athenian tragic poet. He won thirteen victories at tragic competitions (see Theater and Staging) and was credited with having written between seventy and ninety plays. Only seven complete plays survive, all tragedies. Of these, three form a connected trilogy in which the three plays tell a single overarching plot: the Oresteia (Agamemnon, Libation Bearers, Eumenides). Two more were parts of connected trilogies of which the other two plays are lost (Seven against Thebes and Suppliants). One formed part of a trilogy without any close connection to the other plays (Persians), and the authenticity of one is disputed (Prometheus Bound). In addition to his poetic achievement, ancient sources tell us that his epitaph recorded his resistance against the Persians at the battle of Marathon, when, in 490 bce, the Athenians and their allies drove back an attacking Persian horde of vastly superior numbers. It is also possible that Aeschylus fought in the naval battle at Salamis in 480 bce, another Greek victory over the Persians and the subject of his Persians.

Four types of specialized epithelial cells have been observed in the fish tastebud, within the capsule formed by the flattened epidermal cells. However, only two or three of these have been previously noted in any one species, including the glass catfish Kryptopterus bicirrhis, the subject of this investigation (1,2). For the first time, all four types of specialized cells have been observed,and an artifact of fixation relevant to the identification of these cell types has been uncovered.A single basal, or B cell lies on the basement membrane of the epidermis (Fig. 1). It makes many synapses with the afferent nerve plexus, which lies just above it. The other three cell types, designated S,L and T cells (Fig. 2A) are external to the nerve plexus, and only rarely make synapses onto nerves, confirming the observations of several other investigations.

The article describes the use of the anthropomorphic robot ROMA in the educational process. The trends and the main threats associated with the avalanche-like development of robotics and total robotization of society, and the tasks that the teachers face are considered. A small robot ROMA developed at the Kazan Federal University is presented, and its characteristics are described. A comparison is made with the characteristics of foreign analogues, whence it is clear that the presented robot occupies a worthy place in its niche. Various variants for using the ROMA robot in the educational process — from primary school classes to senior university students, are considered. There are educational disciplines and specific topics on which the use of the robot can give a significant impetus to understanding and mastering the subject. On the one hand, this is connected with the students’ interest in the robot as such, and on the other hand, the robot allows to physically demonstrate certain abstract concepts, the effect of algorithm execution, etc. The robot can be used at school for technology lessons. It may be indispensable when studying programming at various levels, 3D modeling, the theory of automatic control, elements of artificial intelligence, pattern recognition, and in a number of other courses. Currently, the process of developing methodological support for various disciplines is underway.

While approaches that had already established historical precedents – computer-assisted analytical approaches drawing on statistics and information theory – developed further, many research projects conducted during the 1980s aimed at the development of new methods of computer-assisted music analysis. Some projects discovered new possibilities related to using computers to simulate human cognition and perception, drawing on cognitive musicology and Artificial Intelligence, areas that were themselves spurred on by new technical developments and by developments in computer program design. The 1990s ushered in revolutionary methods of music analysis, especially those drawing on Artificial Intelligence research. Some of these approaches started to focus on musical sound, rather than scores. They allowed music analysis to focus on how music is actually perceived. In some approaches, the analysis of music and of music cognition merged. This article provides an overview of computer-assisted music analysis of the 1980s and 1990s, as it relates to music cognition. Selected approaches are being discussed.

The purpose of the article is to compare two approaches to analyzing the philosophical and cultural concepts of the Alien that are developing in modern science, to distinguish their specific features and to allow further synthesis. Methodology. System analysis will show the regularity and necessity of studying any encounter with the Other in social reality and must be correlated by the researcher with the configuration of power relations of competing discourses. Results. Drawing on a comparative approach, the author identifies that in both the concept of J. Lacan and the theory of subjection by J. Butler the Other / Alien is an integral part of the personality of the subject. This is a peculiar stage of its formation. Originality. For the first time, the study finds the idea of the subject as alien to oneself. The idea of forming a subject means the experience of communicating with oneself as someone else's (identity crisis), and one of the endpoints of such a process is accepting oneself in a new role, reconciling with oneself in the new capacity of the subject. Practical significance. The information contained in this work can be used for further research and development of methodological material for new courses of lectures and seminars on cultural philosophy and methodology for studying contemporary theories of culture.

The article deals with the problems of a composer's creative work and his own musical piece transcription process by himself. The purpose of this publication is to determine the instrumentation as a factor of the artistic interpretation in the art of composition on the example of fragments from two versions (the piano and the orchestral) of the first part of “Spanish Rhapsody” by M. Ravel. The research is implemented in the bounds of the functional-structural method for the consideration of structural organization components of musical piece fragments, which are studied in the article. A philosophical and aesthetic approach is also applied to found the theoretical part of the article, which defines the interpretative essence of the instrumentation. On the analytical work basis, it is concluded that the instrumentation as a factor of the artistic interpretation in the art of composition touches upon all levels of the organization of musical material, influencing the contents of a musical piece. In this case, the instrumentation correlates with other contents’ components of analyzing fragments and enhances their imaginative characteristics. The subject of the article may be continued in explorations aimed at further analysis and comparison of two versions of the "Spanish Rhapsody" by M. Ravel in sense of the composer’s interpretation context, the timbre and texture interaction or the instrumentation’s interpretational power. It is also possible to direct the vectors of subsequent publications to the way of the melody, rhythm and harmony analysis of this musical composition and their expression in the instrumentation. Research results could be valuable for the educational process in courses of instrumentation, analysis of musical works, interpretation, music history and individual special classes of composition and instrumentation. Fragments from two versions of the first part of the "Spanish Rhapsody" by M. Ravel were analyzed in the context of the interpretative potential of the instrumentation for the first time in this article. A new approach to the musical piece analysis proposed there, aimed at a detailed survey of certain contents’ components of the work and their combined implementation in the timbre.
