Some notes on spaces realized as classifying spaces

In this work, we are concerned with the realization of spaces up to rational homotopy as classifying spaces. In this paper, we first show that a class of rank-two rational spaces cannot be realized up to rational homotopy as the classifying space of any n-connected and π-finite space for n≥1. We also show that the Eilenberg-Mac Lane space K(Qr,n)(r≥2,n≥2) can be realized up to rational homotopy as the classifying space of a simply connected and elliptic space X if and only if X has the rational homotopy type of ∏rSn−1 with n even.

Strategic Planning Peculiarities of an Art Project on the Example of Ukrainian “Jazz Kolo” by I. Zakus: Educational and Social Context

The purpose of the research is to analyze the practical experience of musicians, performers, and participants of an art project, to study the issues of strategic planning of artistic activity and its further interactive realization in the Ukrainian music space on the example of “Jazz Kolo” creative project. The article considers the peculiarities of strategy formation in the organization of an art project, the interaction and relationship of the existence’s parameters and the development of the structure using democratic approaches to dialogue between members of the art team. Possibilities of using research results in the non-formal education of musicians are revealed. The research methodology consists in general scientific methods and approaches in particular: system approach – for structuring and generalization of the organization strategy of a creative project; analytical – to study the scientific and practical experience of this problem; axiological – to identify the importance of the synthesis of artistic, cultural and special professional issues The scientific novelty of the research is the study of the art project in the Ukrainian music space as a complex phenomenon; the components of strategic project planning (artistic performance experiments, educational and social functions, international adaptation and communication, and related activities to create a financial basis, mobility and efficiency of existence, creating content in the market of cultural and artistic services) are substantiated. Conclusions. With a comprehensive approach to creating a model of the organization of an art project, a system of interaction of different cultural environments, active exchange of musical information between countries, project participants enriched the team “Jazz Kolo” and proved that in the formation of a strategic plan of any art business project it is possible to succeed in its implementation, using a decentralized model of group communication, subordinate to the idea and the appropriate team structure.

A Documentation Framework for Sound in Time-based Media Installation Art

ABSTRACT Perhaps because the visual arts predominate in museum collections, conservation documentation methods for audio in time-based media installation art are less developed than those for video. However, the aural elements are equally complex, both technically and creatively. This paper proposes a framework for documenting sound in time-based media installations, from the artist's vision for the listener experience of the artwork to its realization in the exhibition space. This documentation framework was applied to one artwork, The Visitors (2012) by Ragnar Kjartansson, as a case study. The framework and excerpts from the case study show how documentation focused on sound elements can yield unique insights about an artwork. For time-based media works that foreground sound, conservators must be conversant with sound physics, acoustics, audio engineering, and sound design so that they can have productive conversations with artists, sound professionals, and other stakeholders in order to create meaningful documentation of the significant aural properties of an artwork for the future. In this way, conservators can approach time-based media installations not only attending to how they look, but also to how they sound.

Crisis on infinite earths: short-lived de Sitter vacua in the string theory landscape

We construct purely non-perturbative anti-de Sitter vacua in string theory which, on uplifting to a de Sitter (dS) one, have a decay time many orders of magnitude smaller than those of standard constructions, such as the KKLT and LVS scenarios. By virtue of being constructed purely from non-perturbative terms, these vacua avoids certain obstructions plaguing other constructions of dS in string theory. This results in a new class of phenomenological dS vacua in string theory with novel distinctive characteristics such as having two maxima. After examining whether these uplifted dS vacua obey the TCC, we revisit some old problems of realization of dS space as a vacuum. We find that not only is it phenomenologically hard to construct TCC-compatible vacua, but also inherent temporal dependences of the degrees of freedom generically arise in such constructions, amongst other issues. This reinforces the idea that dS, if it exists in string theory, should be a Glauber-Sudarshan state and not a vacuum.

De Sitter space as a Glauber-Sudarshan state

Glauber-Sudarshan states, sometimes simply referred to as Glauber states, or alternatively as coherent and squeezed-coherent states, are interesting states in the configuration spaces of any quantum field theories, that closely resemble classical trajectories in space-time. In this paper, we identify four-dimensional de Sitter space as a coherent state over a supersymmetric Minkowski vacuum. Although such an identification is not new, what is new however is the claim that this is realizable in full string theory, but only in conjunction with temporally varying degrees of freedom and quantum corrections resulting from them. Furthermore, fluctuations over the de Sitter space is governed by a generalized graviton (and flux)-added coherent state, also known as the Agarwal-Tara state. The realization of de Sitter space as a state, and not as a vacuum, resolves many issues associated with its entropy, zero-point energy and trans-Planckian censorship, amongst other things.

Dreaming and Experiencing in the Potential Space

The author presents some clinical sequences from two sessions in order to illustrate his thoughts about dreaming, about experiencing in analysis, and about the clinical realization of the potential space. When the dreamer’s conscious and unconscious relationship with her own dream turns the latter into a living psychic object, the experience that the dreamer can have of the dream occupies an intermediate area, placing itself between the internal world and external reality. When the dreamer lets the dream-experience affect the experience of external reality, a further transformation can take place in the analysis, since this intermediate intrapsychic area can become a transitional area between the patient and the analyst. The analyst and the patient were able to create a potential space in which, in addition to the transference repetition of cumulatively traumatic situations, an experience was generated that gave rise to embryonic processes of integration between dissociated aspects of the patient.

EVEKTIFITAS PEMANFAATAN RUANG TERBUKA PUBLIK DI TAMAN SULTAN HASANUDDIN GOWA

The importance of the existence of Green Open Space (RTH) in urban areas has begun to be felt by the community at this time. By looking at the phenomenon of the many public open spaces that are changing their faces into new high-rise buildings and housing, it has encouraged the enthusiasm of some people to restore the role of public space in urban areas. Various environmentalists took part, including the government through the Ministry of Public Works and Public Housing, various communities including the implementers of the 2015 world habitat day activity (HHD2015) and writers, to voice the urgency of public space and share ideas and strategies for encourage the realization of public space for all communities. Sultan Hasanuddin Park is a park located in Gowa Regency, but it is not passed by public transportation. Sultan Hasanuddin Park also has several supporting facilities but it does not function properly and some have been damaged. This study uses a qualitative descriptive method, which describes a phenomenon, events and conditions that exist. This study aims to Analyze the pattern of spatial use in Sultan Hasanuddin Park, Identify factors influencing the effectiveness of the utilization of the Sultan Hasanuddin Makassar Park facility and Analyze the utilization of supporting facilities for Sultan Hasanuddin Park as a public open space. The results showed that the Sultan Hasanuddin Park did not function properly, due to the lack of shade in the seating area, so that the upholders sat in a shaded area and not in the proper seat. The absence of a clear parking area so that the end of the park in the park and the absence of public bins so that one corner of the park used as public TPU. Lack of care / janitors who take care of the park so that plants and grasses that exist in the garden are not maintained.

Права сучасної української молоді в інформаційному просторі України

У статті розглядаються проблемні питання реалізації прав сучасної української молоді в інформаційному просторі України, з’ясовано, що актуальність завдань зростає, починаючи з XVII століття, агресивною політикою інформаційних інтервенцій сусідньої держави. Виявлено, що з 1991 року Росія намагалася втягнути Україну в поле власних інтеграційних інтересів, а український інформаційний простір наповнюється «українськими версіями» популярних російських газет і журналів, сторінки яких містять проросійські матеріали. Описана хронологія ядерного нищення українського інформаційного простору протягом XVII-XX століть, що не дало можливості українській молоді з XVII століття та майже за тридцять років незалежності ХХІ століття, отримати права на власний український інформаційний простір. Встановлено, що в українському інформаційному просторі майже всі ЗМІ представляють або окремі фінансово-політичні групи або належать іноземним власникам, які явно або через треті країни діють в пропагандистській парадигмі РФ. З’ясовано, що сучасний інформаційний простір незалежної України донині залишається незахищеним та вразливим до проникнення російської ідеологічної риторики. Політичний істеблішмент легко та відкрито використовує вказану риторику у власних, зовсім не державницьких цілях. Досліджено фундаментальні засади, складові елементи та етапи формування українського інформаційного простору в контексті реалізації прав молоді. Загалом диференціація актуальних проблем в українському інформаційному просторі відбувається навколо таких парадигм: політико-ідеологічної, економічної та гуманітарної. З 2019 року український інформаційний простір окреслює концептуальні засади реалізації політики Росії щодо України, втіленої в концепції «Русский мир», «Третій Рим». Встановлено, що в українському інформаційному просторі широко представлено реалізацію проросійських олігархічних інтересів, інтересів бізнес-корпорацій, що зумовлює посилення російського впливу, формування позитивного іміджу Росії за рахунок реалізації прав української молоді.

Scattering equations: from projective spaces to tropical grassmannians

We introduce a natural generalization of the scattering equations, which connect the space of Mandelstam invariants to that of points on ℂℙ1, to higher-dimensional projective spaces ℂℙk − 1. The standard, k = 2 Mandelstam invariants, sab, are generalized to completely symmetric tensors {mathrm{s}}_{a_1{a}_2dots {a}_k} subject to a ‘massless’ condition {mathrm{s}}_{a_1{a}_2dots {a}_{k-2}bb}=0 and to ‘momentum conservation’. The scattering equations are obtained by constructing a potential function and computing its critical points. We mainly concentrate on the k = 3 case: study solutions and define the generalization of biadjoint scalar amplitudes. We compute all ‘biadjoint amplitudes’ for (k, n) = (3, 6) and find a direct connection to the tropical Grassmannian. This leads to the notion of k = 3 Feynman diagrams. We also find a concrete realization of the new kinematic spaces, which coincides with the spinor-helicity formalism for k = 2, and provides analytic solutions analogous to the MHV ones.

Features of Teaching Russian to Students from the Republic of Angola

The article deals with the problematic issues of teaching Russian to students from the Republic of Angola. In particular, attention is drawn to the study of the topic of Russian prepositions. The author of the article conducts a comparative analysis of the meaning of prepositions «in/to» and «through/across» in Portuguese and Russian languages, highlighting their similarities and differences in speech. Among the reasons that cause difficulties in the perception of this topic, the author, among other things, points to extra-linguistic factors: national languages, place and method of resettlement of students, their social affiliation, cultural and linguistic features, and language picture of the world, worldview, culturally conditioned contacts, and the prevalence of the language. The presence of the above factors predetermines the teaching methods of this group of students. The article also discusses the impact of globalism on students and on the process of learning the Russian language. The features of syncretic cultures, the reasons of their origin and realization in modern cultural space of the world are noted.

The Virtual Dimension of Legal System

The purpose of the present research is identification of existence of legal system in space. This purpose is concretized by the following tasks: the analysis of existence of positive law, legal science, legal consciousness in measurement; disclosure of some features of law-making on the Internet; identification of separate aspects of right realization in space. The methodological device of this research is based on dialectic understanding of surrounding life in which borders between real and space have flexible character. At the same time use of the system approach causing existence of various methods of scientific knowledge is inevitable. It is possible to distinguish from them structurally functional, legalistic, and comparative and other methods. Authors of article recognize the known pluralism of the used categories. However in this research the terms virtual space, digital space, Internet space, cyberspace are used as synonyms. Results of the research can find the application in the sphere of jurisprudence and legal education. Also they can be considered in law-making processes.

MILP-Based Optimization of 2-D Block Masks for Timing-Aware Dummy Segment Removal in Self-Aligned Multiple Patterning Layouts

Self-aligned multiple patterning, due to its low overlay error, has emerged as the leading option for 1-D gridded back-end-of-line (BEOL) in sub-14-nm nodes. To form actual routing patterns from a uniform “sea of wires,” cut masks are needed for line-end cutting or realization of space between routing segments. The line-end cutting results in nonfunctional (i.e., dummy fill) patterns that change wire capacitance, and hence design timing and power. Therefore, to remove such dummy fill patterns, extra 2-D block masks are used. However, 2-D block masks cannot remove arbitrary dummy fill patterns, due to design rule constraints on the block mask shapes. In this paper, we address the timing-aware optimization of 2-D block mask layouts under various sets of mask rules that are derived from mask patterning technology options (e.g., 193i and 193d) for foundry 7-/5-nm (N7/N5) BEOL. Our central contribution is a mixed integer linear programming (MILP) optimization that minimizes timing impact due to dummy metal segments while satisfying block mask rules and metal density constraints. We also propose a distributed optimization flow to improve the scalability. With our optimizer, we recover up to 84% of the worst negative slack impact from dummy segments, with up to 64% dummy removal rate. We further extend our MILP to a co-optimization of cut and block masks. This paper gives new insights into fundamental limits of benefit from emerging cut and block mask technology options.

Monotonicity of strata in the stratification of the cone of totally positive matrices

According to a theorem of Bjorner [5], there exists a stratified space whose strata are labeled by the elements of [u, v] for every interval [u, v] in the Bruhat order of a Coxeter group W, and each closed stratum (respectively the boundary of each stratum) has the homology of a ball (respectively of a sphere). In [6], Fomin and Shapiro suggest a natural geometric realization of these stratified spaces for a Weyl group W of a semi-simple Lie group G, and then prove its validity in the case of the symmetric group. The stratified spaces arise as links in the Bruhat decomposition of the totally non-negative part of the unipotent radical of G. In this article, we verify the topological regularity property of the strata formed as a result of Bruhat partial ordering on the elements of theWeyl group (of rank 4) of a semi-simple simply connected algebraic group G which is SL(4,ℝ) in our case here. The Weyl group here is the Coxeter group S 4.

Geometry of the equilibrium distribution of interacting particles

The formations of structures in all systems of interacting particles at different temperatures and particle concentrations have the same physical nature and therefore they could be described geometrically the same way. We propose a geometric description of a thermodynamically stable distribution of interacting particles. The character and intensity of interaction between particles determine the effective geometry of the medium which is provided by the minimum of the total free energy with non-linearity. A realization of spaces with possible particle distributions of arbitrary-order symmetries (including fifth, seventh etc. orders) which cannot occur in the ordinary Euclidean space, is described.

Period polynomial relations of binomial coefficients and binomial realization of formal double zeta space

In this paper, we give a realization of the formal double zeta space by using binomial coefficients. Along with the results in [Period polynomial relations between formal double zeta values of odd weight, Math. Ann. 365 (2016) 345–362], this gives us two families of period polynomial relations among binomial coefficients. We also give another family of period polynomial relations among binomial coefficients which cannot be obtained from our binomial realization. At the end, some higher depth observation is provided.

Four basic classes of conflicts experienced by recently graduated teachers, and such conflicts are analyzed with support on concept of Third Space.

PROBLEM OF THE INTERACTION OF THE ADDITIONAL PROFESSIONAL EDUCATION WITH OTHER EDUCATIONAL SYSTEMS IN TERMS OF ACTIVE STANDARDIZATION OF EDUCATION

The article is devoted to the problem of interaction of additional professional education with educational systems in terms of standardization of modern domestic education. Set out the understanding of the additional professional education as an organized and socially determined educational process, contributing to the assimilation of adult scientific achievements, cultural-historical and spiritual-moral values of society through the development of additional professional programs; as a set of additional vocational programs with the purpose of professional development, training, retraining. The role of additional professional education in the system of continuous education of adults is analyzed. It is established that the interaction of the additional professional education with other educational systems is based on modern paradigm of the system of additional education as an open educational system based on constant interaction with the external environment. In modern conditions a priority in the development of additional professional education be the trends the provision of educational services by combining educational resources of different educational institutions of the normative embodied in the new national education standards. Presents the advantages of network interaction between system additional professional education and educational organizations, which allows you to build relationships based on equality and mutual interest in joint realization of innovative educational space. Identified problems in the network communication system additional professional education and educational organizations, which serve the unwillingness of subjects of education to implement network communication, the problems of organization of network interaction, and the lack of uniform networked educational structure. It is shown that the effective interaction of the additional professional education system with other educational systems is realized on the basis of the resource centers of additional education of adults on the basis of network interaction between subjects of education.

Parallel satellite orbital situational problems solver for space missions design and control

Solving different scientific problems for space applications demands implementation of observations, measurements or realization of active experiments during time intervals in which specific geometric and physical conditions are fulfilled. The solving of situational problems for determination of these time intervals when the satellite instruments work optimally is a very important part of all activities on every stage of preparation and realization of space missions.The elaboration of universal, flexible and robust approach for situation analysis, which is easily portable toward new satellite missions, is significant for reduction of missions’ preparation times and costs.Every situation problem could be based on one or more situation conditions. Simultaneously solving different kinds of situation problems based on different number and types of situational conditions, each one of them satisfied on different segments of satellite orbit requires irregular calculations.Three formal approaches are presented. First one is related to situation problems description that allows achieving flexibility in situation problem assembling and presentation in computer memory. The second formal approach is connected with developing of situation problem solver organized as processor that executes specific code for every particular situational condition. The third formal approach is related to solver parallelization utilizing threads and dynamic scheduling based on “pool of threads” abstraction and ensures a good load balance.The developed situation problems solver is intended for incorporation in the frames of multi-physics multi-satellite space mission’s design and simulation tools.
