This book develops a general analysis and synthesis framework for impulsive and hybrid dynamical systems.

This book places thermodynamics on a system-theoretic foundation so as to harmonize it with classical mechanics. Using the highest standards of exposition and rigor, the authors develop a novel formulation of thermodynamics that can be viewed as a moderate-sized system theory as compared to statistical thermodynamics. This middle-ground theory involves deterministic large-scale dynamical system models that bridge the gap between classical and statistical thermodynamics. The authors' theory is motivated by the fact that a discipline as cardinal as thermodynamics--entrusted with some (...) of the most perplexing secrets of our universe--demands far more than physical mathematics as its underpinning. Even though many great physicists, such as Archimedes, Newton, and Lagrange, have humbled us with their mathematically seamless eurekas over the centuries, this book suggests that a great many physicists and engineers who have developed the theory of thermodynamics seem to have forgotten that mathematics, when used rigorously, is the irrefutable pathway to truth. This book uses system theoretic ideas to bring coherence, clarity, and precision to an extremely important and poorly understood classical area of science. (shrink)

The review of the theory of electromagnetic field together with the special and general theories of relativity has been made. The similar theory of gravitation has been presented which has the property of Lorentz-invariancy in its own representation in which the information is transferred at the speed of propagation of the gravitational field. Generalization of the specified gravitation theory on noninertial reference systems has been made with the help of the mathematical apparatus of the general relativity. It allows to avoid (...) some drawbacks of the standard general relativity theory and to expand its applicability. The possibility of complementary descriptions of the physical phenomena with the help of simultaneous use of the theories of gravitational and electromagnetic fields has been shown. (shrink)

ISBN 978-5-86007-556-6. (in Russian). -/- In the book we can find the analysis of some closely related problems – of the origin and essence of life, the universal world process and the global evolution. Examination of fractal nature of carriers through the distribution of terrestrial and space objects on the steps of scale staircase, depending on the masses and sizes, shows an appropriate relationship with the masses and sizes of live organisms. One of the conclusions is the complementarity of living (...) and nonliving carriers in universe, and the main difference between a living from nonliving matter is an independent source of ordering inherent in living forms and managing all of its reactions.

With the help of syncretiсs as a new philosophical logic, the philosophy of carriers, the theory of similarity and the theory of Infinite Hierarchical Nesting of Matter, the problems of modern physics are analyzed. We consider the classical and relativistic mechanics, the special and general theories of relativity, the theory of electromagnetic and gravitational fields, of weak and strong interactions. The goal is axiomatization of these theories, building models of elementary particles and of their interactions with each other. The main (...) obtained results are: the model of bead lightning; an explanation of redshift of the spectra of galaxies; the derivation of the Newton law in the concept of gravitons; the calculation of nuclear forces and the structure of simplest nuclei with the help of the theory of strong gravitation; building the model of weak interactions of elementary particles; presentation of quarks as a particular type of quasiparticles; explanation of the electron spin. The book should be useful for students and researchers, as well as for those interested in physical and philosophical problems. Tables 20. Fig. 30. Ref. 155 titles. (shrink)

Historical experience shows that politics, despite all its shortcomings, is the best tool created by people to organize the common life of large groups of the population and manage them. Therefore, the desire of thinkers of all times and peoples to obtain knowledge about politics is understandable, which, in its rigor, clarity, and accuracy of forecast, would be comparable to scientific knowledge. The present review analyzes the works of the Russian social scientist Viktor P. Makarenko, who researched the triad “politics–authority–bureaucracy” (...) for fifty years. The result was the creation of a political conceptology, which the author positions as a transdisciplinary approach to the study of politics. Analytical philosophy became the theoretical and methodological platform of political conceptology. The monographs, articles, and speeches of Makarenko reflect the process of establishing the author’s position, expanding the scope of problems, identifying additional points of contact between bureaucracy and politics, as well as improving the methodology of political analysis.

The article deals with diversity of language signs in legal terminology. The aim of the article is to show the influence of both linguistic and extra-linguistic factors on the specificity of various linguistic units in the legal terminology. Though all terminological systems possess some similar features, there may be certain traits characteristic only for some of them. As specific systems of signs, legal terminologies show some peculiarities that are discussed in the article from the point of view of oppositions to (...) highlight the semiotic specifics of language units used by lawyers and also the organization of the terminological system under consideration. The oppositions under consideration emerge due to both linguistic and extra-linguistic factors. Extra-linguistic factors determine such oppositions as terminology of law: terminology of jurisprudence, modern terminology: historical terminology, terms: nomenclature signs. Linguistic factors stipulate the opposition of primary and derived terms. A combination of linguistic and extra-linguistic factors determines the following oppositions: native terms: borrowed terms, terms of the basic terminological system: terms attracted from other spheres of knowledge. Within these types of oppositions a number of more specific ones were elicited. The interaction of synchronic and diachronic approaches the article is based on allowed the authors to focus on the permanent semantic properties of the language signs pertaining to tribal customary and modern law, and on those emerging in the course of the evolution of law.

The article proposes a universal dual-axis intelligent systems assessment scale. The scale considers the properties of intelligent systems within the environmental context, which develops over time. In contrast to the frequent consideration of the “mind” of artificial intelligent systems on a scale from “weak” to “strong”, we highlight the modulating influences of anticipatory ability on their “brute force”. In addition, the complexity, the ”weight“ of the cognitive task and the ability to critically assess it beforehand determine the actual set of (...) cognitive tools, the use of which provides the best result in these conditions. In fact, the presence of ”common sense“ options is what connects the ability to solve a problem with the correct use of such an ability itself. The degree of ”correctness“ and ”adequacy“ is determined by the combination of a suitable solution with the temporal characteristics of the event, phenomenon, object or subject under study. The proposed approach can be applied in the evaluation of various intelligent agents in different contexts including AI and humans performing complex domain-specific tasks with high uncertainty.

This article considers how people judge the identity of objects (e.g., how people decide that a description of an object at one time, t₀, belongs to the same object as a description of it at another time, t₁). The authors propose a causal continuer model for these judgments, based on an earlier theory by Nozick (1981). According to this model, the 2 descriptions belong to the same object if (a) the object at t₁ is among those that are causally close (...) enough to be genuine continuers of the original and (b) it is the closest of these close-enough contenders. A quantitative version of the model makes accurate predictions about judgments of which a pair of objects is identical to an original (Experiments 1 and 2). The model makes correct qualitative predictions about identity across radical disassembly (Experiment 1) as well as more ordinary transformations (Experiments 2 and 3). (shrink)

The formalism of general probabilistic theories provides a universal paradigm that is suitable for describing various physical systems including classical and quantum ones as particular cases. Contrary to the usual no-restriction hypothesis, the set of accessible meters within a given theory can be limited for different reasons, and this raises a question of what restrictions on meters are operationally relevant. We argue that all operational restrictions must be closed under simulation, where the simulation scheme involves mixing and classical post-processing of (...) meters. We distinguish three classes of such operational restrictions: restrictions on meters originating from restrictions on effects; restrictions on meters that do not restrict the set of effects in any way; and all other restrictions. We fully characterize the first class of restrictions and discuss its connection to convex effect subalgebras. We show that the restrictions belonging to the second class can impose severe physical limitations despite the fact that all effects are accessible, which takes place, e.g., in the unambiguous discrimination of pure quantum states via effectively dichotomic meters. We further demonstrate that there are physically meaningful restrictions that fall into the third class. The presented study of operational restrictions provides a better understanding on how accessible measurements modify general probabilistic theories and quantum theory in particular. (shrink)

In the “Critique of Pure Reason” and subsequent “Prolegomena to Any Future Metaphysics...”, “Metaphysical Principles of Natural Science”, “Opus Postumum” Kant develops one of the modes of his transcendentalism, the metaphysics of possible experience, whose task is to study the transcendental conditions for the possibility of our (cognition), which, according to Kant, has a priori character. P. Strawson calls this mode of metaphysics ‘ descriptive metaphysics ’ and connects it with the analyzing the ‘conceptual structure’ of our thinking about the (...) world. The contemporary realistic trend (primarily within the framework of the analytical philosophical tradition) in the interpretation of Kant’s transcendental philosophy is associated with the modern theory of “two aspects” (80s of the 20th century), which replaced the classical theory of “two objects/worlds” (compare also with the opposition “ theory of appearance vs. theory of appearances ”). Within the framework of this theory, the Kantian ‘appearance’ receives an objectified status, it is not our mental representation, but corresponds (as its signs) to really existing things, or Kantian ‘objects of experience’. The article traces the formation of the historical and conceptual background of the ‘ metaphysics of experience ’ (H. Paton's original expression). Historically, the metaphysics of experience inherits the neo-Kantian approach to interpreting Kant's transcendentalism as a ‘theory of experience’ (H. Cohen, E. Cassirer), then it develops in logical positivism/empiricism (H. Reichenbach, R. Carnap; further in post-posivivism: the theory of I. Lakatos and T. Kuhn), analytical philosophy of science (W. Sellars, G. Buchdal, H. Putnam), and at present the metaphysics of experience is developing in a number of contemporary works of an analytical orientation (P. Strawson, K. Ameriks, L. Allais and etc.). (shrink)

The paper discusses the Strawsonian concept of descriptive metaphysics and its various implementations in conceptions of I. Kant, R.G. Collingwood and P.F. Strawson, their similarities and differences. Particular attention is paid to the analysis of Kant's transcendental philosophy (resp. transcendental idealism), or its metaphysics of appearance as a pioneer version of descriptive metaphysics and its comparison with the version of descriptive metaphysics of P. Strawson himself.

We develop a general theory of FDE-based modal logics. Our framework takes into account the four-valued nature of FDE by considering four partially defined modal operators corresponding to conditions for verifying and falsifying modal necessity and possibility operators. The theory comes with a uniform characterization for all obtained systems in terms of FDE-style formula-formula sequents. We also develop some correspondence theory and show how Hilbert-style axiom systems can be obtained in appropriate cases. Finally, we outline how different systems from the (...) literature can be expressed in our framework. (shrink)

We prove that a propositional Linear Temporal Logic with Until and Next has unitary unification. Moreover, for every unifiable in LTL formula A there is a most general projective unifier, corresponding to some projective formula B, such that A is derivable from B in LTL. On the other hand, it can be shown that not every open and unifiable in LTL formula is projective. We also present an algorithm for constructing a most general unifier.

The specificity of eukaryotic DNA organization into loops fixed to the nuclear matrix/chromosomal scaffold has been studied for more than fifteen years. The results and conclusions of different authors remain, however, controversial. Recently, we have elaborated a new approach to the study of chromosomal DNA loops. Instead of characterizing loop basements (nuclear matrix DNA), we have concentrated our efforts on the characterization of individual loops after their excision by DNA topoisomerase II‐mediated DNA cleavage at matrix attachment sites. In this review (...) the results of applying this mapping approach are compared with the results and conclusions from studies of nuclear matrix DNA. An attempt is also made to reconsider all data about the specificity of DNA interactions with the nuclear matrix and to suggest a model of spatial organization of the eukaryotic genome which resolves apparent contradictions between these data.

This paper is dedicated to developing a formalism that takes rejection seriously. Bilateral notation of signed formulas with force indicators is adopted to define signed consequences which can be viewed as the bilateral counterpart of Tarskian consequence relations. Its relation to some other bilateral approaches is discussed. It is shown how David Nelson’s logic N4 can be characterized bilaterally and the corresponding completeness result is proved. Further, bilateral variants of three familiar notions are considered and investigated: that of a fragment, (...) of definitional equivalence, and of a conservative extension. (shrink)

We present novel proof systems for various FDE-based modal logics. Among the systems considered are a number of Belnapian modal logics introduced in Odintsov & Wansing and Odintsov & Wansing, as well as the modal logic KN4 with strong implication introduced in Goble. In particular, we provide a Hilbert-style axiom system for the logic $BK^{\square - } $ and characterize the logic BK as an axiomatic extension of the system $BK^{FS} $. For KN4 we provide both an FDE-style axiom system (...) and a decidable sequent calculus for which a contraction elimination and a cut elimination result are shown. (shrink)

We exploit properties of certain directed graphs, obtained from the families of sets with special effective enumeration properties, to generalize several results in computable model theory to higher levels of the hyperarithmetical hierarchy. Families of sets with such enumeration features were previously built by Selivanov, Goncharov, and Wehner. For a computable successor ordinal α, we transform a countable directed graph into a structure such that has a isomorphic copy if and only if has a computable isomorphic copy.A computable structure is (...) categorical if for all computable isomorphic copies of , there is an isomorphism from onto , which is . We prove that for every computable successor ordinal α, there is a computable, categorical structure, which is not relatively categorical. This generalizes the result of Goncharov that there is a computable, computably categorical structure, which is not relatively computably categorical.An additional relation R on the domain of a computable structure is intrinsically on if in all computable isomorphic copies of , the image of R is . We prove that for every computable successor ordinal α, there is an intrinsically relation on a computable structure, which not relatively intrinsically . This generalizes the result of Manasse that there is an intrinsically computably enumerable relation on a computable structure, which is not relatively intrinsically computably enumerable.The dimension of a structure is the number of computable isomorphic copies, up to isomorphisms. We prove that for every computable successor ordinal α and every n≥1, there is a computable structure with dimension n. This generalizes the result of Goncharov that there is a structure of computable dimension n for every n≥1.Finally, we prove that for every computable successor ordinal α, there is a countable structure with isomorphic copies in just the Turing degrees of sets X such that relative to X is not . In particular, for every finite n, there is a structure with isomorphic copies in exactly the non- Turing degrees. This generalizes the result obtained by Wehner, and independently by Slaman, that there is a structure with isomorphic copies in exactly the nonzero Turing degrees. (shrink)

This article deals with voice and bodily deixis as manifestations of performativity in written texts. A speech act of origin presents as both vocal and performative events. Ritual matrixes of culture contain performative complexes, as suggested by Austin. Such performative nuclei are neither true nor false, that is, their negation cannot be logically inferred from true premises. The term deixis describes the performative moment of the utterance, its active and transformative force. The first embodied deictic utterance in Western history would (...) be the biblical phrase “And the word made flesh.” It is the first mythopoetical performative denoting the bodily incarnation of logos. In the article, the term bodily deixis is considered against the background of experimental poetry of E.E. Cummings. (shrink)

The article focuses the possibility of elaboration of a cross-disciplinary methodological approach to formation of the semiotics of power. Four possible forms of relation of semiotic research to the problem of power are revealed upon the basis of Drechsler’s typology. The approaches of Mandoki and Siefkes to formation of the methodological basis of the semiotics of power are analyzed and compared. The author designates the perspective directions of a further research and formulates methodological prerequisites for realization of the specified directions.

The belief in the Darwinian theory of evolution appeared to be shaken when one tried to interpret statements of molecular biology in it. As a consequence there arose a theory of non-Darwinian neutral evolution. The supporters of this theory believe that under natural conditions no factors exist which can distinguish and select organisms on their internal (molecular) structure. In the opinion of these neutralists natural selection cannot in principle control the molecular constitution of organisms. Contrary to the viewpoint of the (...) critics of neutralism it is impossible to admit that nucleic acids, proteins and other biomolecules can evolve without the participation of natural selection. This controversy in contemporary theoretical biology can be solved by integrating the conceptions of molecular ecology with Darwinian theory. Molecular ecology acknowledges the interactions of organisms by means of chemical substances synthesized by them. Such chemical ecological factors play a leading part in the selective stages of biomolecular evolution. These diverse chemical ecological interrelations take place intensively when living beings interact with parasitic microbes. (shrink)

The writings in which an author expresses his thought may actually be the product of certain cultural practices of his age. The article considers how such practices are manifested in the writings of Isidore of Seville, particularly with respect to the meaning of the metaphor of taste. Isidore borrows this metaphor from texts that explain the process of understanding Scripture and applies it to the achievement of wisdom. On the one hand, the metaphor stresses the transformative aspect of understanding (rather (...) than the informative, scientia). It focuses on the special experience of the reader who senses the sweetness of the text, and not on the application of the text to one’s life. On the other hand, reading and writing were imagined in terms related to food. The text was food that had to be prepared, to ‘read’ meant to ‘taste’, to ‘meditate’ on it meant to ‘ruminate’. Against this background, the writings of Isidore seem to appeal to the memory of the reader and his ability to meditate upon the text and, finally, to experience the taste of wisdom. Only the outermost level of texts was intended to inform the reader. (shrink)

In the course of a close analysis of Kant’s essay in which he gives his original answer to the question, “What is Enlightenment?” I examine the causes and consequences of the theses about Enlightenment which makes a plea for emancipation from the shackles of guardianship, above all by getting rid of one’s own cowardice. In search of an answer to the question, “What is the real reason of self-incurred immaturity?” I consider the bifurcation: Is it all about unjust social institutions (...) established in the interests of the ruling social estates, as the best European brains contended throughout the Enlightenment era, thus anticipating and justifying revolutionary upheavals, or is it within ourselves who have refused to use our reason independently and regularly? — something which Kant unequivocally considers to be everyone’s special kind of guilt. Following Kant, I look for an answer to the question, “Which limits impede Enlightenment, and which limits, far from obstructing it, are bound to promote it?” and reveal the hidden paradox of the Kantian solution: maturity has to be preceded by the granting of freedoms; and the granting of freedoms in turn calls for a mature public. I also ask the question, “Whose yoke is heavier, one’s own or the guardian’s?” and offer my version of an answer. In conclusion, I assemble all parts of the complicated and original formula of the Kantian recipe of Enlightenment. Among other things, I reveal a special type of bonding within the social organism implied by Kant, and that is the requirement to obey those who are not above us in thinking and the right to speak out in public, which ultimately means not only personal maturity, but implies also the maturity of society’s functioning in accordance with the said maxim.

The logic with independent truth and falsehood operators TFL is proposed. In TFL(→) standard truth-conditions for the implication are adopted. Nevertheless the laws of classical logic are not valid. In this language more then 107 different binary connectives can be defined. So this logic can be treated as universal logic relatively to the class of sentential logics.

The Greek Prophetologion manuscript Q12 from the library of the Academy of Sciences in St. Petersburg, copied in 1275, contains some thirty marginal notes written in Alanic, a pre-stage of Ossetic. On leaf 100r, the glossator provided the Greek heading τ παραμο(ν) τς μέ(σο) ν´ (i.e. μεσοπεντηκοστς), ‘Eve of Mid-Pentecost’, with a gloss πητζινάκ χουτζάου πάν which most probably means ‘Pecheneg Sunday’. A Pecheneg festival established after the decisive victory of John II over the Pechenegs is attested by both Nicetas (...) Choniates and Ecloga Basilicorum. It is no wonder that this festival reached distant Alania, since the 12th century was a heyday for the Orthodox Christianity in the Northern Caucasus. The battle took place near Beroea in spring of the “fifth year” of John II's reign. The majority of historians tend to opt for 1122, but we would not exclude 1123 either. Whatever the year, the marginal note from Q12 may help in establishing the day of the battle, which is not mentioned either in Greek or in Scandinavian sources. If the battle of Beroea took place in 1122, it happened either on the 20th–22nd or on the 24th–26th of April. If the battle was fought in 1123, the day of the victory could then be either the 10th–12th or the 14th–16th of May. (shrink)

The paper deals with the expression "God is able to make a calf from a tree-trunk"—a very popular phrase in medieval treatises, especially in the context of God's omnipotence. Its attestations are thoroughly documented and considered, contexts discussed, and attributions examined. It is argued that the attribution to Anselm of Canterbury is false and late. It is claimed that the phrase goes back to a popular saying as attested by William of Conches, Peter Comestor, and ps.-Bonaventurian Ars concionandi. Thus, it (...) is a rare example of a rustic proverb used in scholastic debates as a standard scholarly argument. (shrink)

This article considers late additions to the miracles of Antichrist as found in fifteenth-century manuscripts such as Wellcome Library, MS 49 and the Antichrist-Bildertext. One of these miracles—a castle hanging by a thread—has a parallel in the German nonsense poetry tradition. The poem ‘Sô ist diz von lügenen’ from a fourteenth-century manuscript depicts a topsy-turvy world where Rome and the Lateran also hang by a thread. Subsequently the same motif occurs in the Emblemata of Théodore de Bèze (1580). A tense (...) interaction of text and image is a characteristic feature of this motif, which seems to be a local German invention. The borrowing from a tall tale into an eschatological legend, unusual as it seems, underscores the closeness of the topsy-turvy world of the popular imagination and the apocalyptical narrative with the Antichrist playing a demonstrably parodical part.

Personal branding has become an important concept in management literature in recent years. Yet, with more than 100 scholarly papers published on the concept to date, it has developed into a fragmented area of research with a diversity of definitions and conceptual boundaries. This paper posits that this heterogeneity of extant research impedes theoretical and empirical advancement. To strengthen the foundation for future work, we review the extant literature and offer an integrative model of personal branding. Through our systematic literature (...) review we identify the key attributes of the construct, establish its clarity by comparing it with similar concepts in its nomological network, and suggest the definitions of personal branding and personal brand based on the reviewed literature. Further, we propose a theoretical model of personal branding summarizing the findings from the reviewed papers. The proposed model outlines the trends conducive to personal branding, as well as its drivers, processes, and outcomes. Finally, we discuss ethical implications of personal branding for both scholarly work and practice. In conclusion, we outline a further research agenda for studying personal branding as a critical career and organizational behavior activity in contemporary working environment. (shrink)

Nammalvar, a Tamil poet who lived in IX-X centuries, is revered as one of the great mystics of India. His four poetic works are equated with the sacred hymns and are part of the ritual worship in the temples of South India. Artistic images of Nammalvar formed the basis of the philosophy of Vishishta-Advaita several centuries later. The poem “Thiruviruttam” is considered as his early work, where he combines the canons of ancient Tamil poetry and his devoted love for Vishnu-Tirumal. (...) The study presents a religious and philosophical interpretation of the poem. The secret of the poem is its dualism: external beauty and sacred meaning. There is a spiritual meaning in symbols of Tamil poetry. Nammalvar takes canons of his predecessors, poets of the Sangam era. However, he fills one with new content. The author compares ancient Tamil poetry and the work of Nammalvar. The plot describes the love between God and the soul. The poet reveals several types of bhakti or devoted love. The description of bhakti subsequently formed the basis for the classification of souls in the philosophy of vishishta-advaita. Bhakti leads to the transition to Vaikuntha or the heaven city. Sri Vaishnavism teachers turned the description of relationship soul-Vishnu into a spiritual practice. The artistic images of Nammalvar are compared with Hindu concepts such as transcendence, darshan, divine grace and moksha. In South India “Thiruviruttam” is considered the Tamil Rig Veda. Poem is performed at home, in the temple, during festive processes. It helps to find the roots of Vaishnavism and understand its poetic origin. (shrink)
