New conditions, technological capabilities and development prospects of the geodetic industry in recent time are characterized. The directions and strategy of the developing the industry, aimed at increasing its national importance by expanding the field of activity from the level of geoinformation to the level of its widespread use are substantiated. The solutions and tasks for the transfer of geo-information activities to a digital basis are listed. The definition of the geospatial activity’s concept is given. The conceptual structure and essentially new directions of geospatial support development of territories taking into account the perspective are offered. They are creating a single territorial geo-information space, designing and developing geo-cognitive technologies for forming geospatial knowledge, developing geo-cognitive technologies for preparing geo-spatial solutions to ensure territorial development and management. The technological levels of formalization and use of geospatial knowledge at preparing spatial solutions are considered. The forecast of expected efficiency received from geospatial activity in the digital economy is given. The scientific and technical directions for the successful geospatial supporting the spatial development of the country and solving tasks of transition to the digital economy are listed.

The Introduction explains the combination of a narrative arc and conceptual structure in the organization of the book. The former, primarily diachronic, discussion is concerned with the development of the field of Romanticism since the 1980s, presented through both a review of scholarship and exemplary readings of well-known lyric poems. The latter, predominantly synchronic, presentation entails an argument for the analytical value of field theories of form—that is, frameworks drawn from early modern philosophy (Spinoza) and postclassical life- and physical sciences, especially models of self-organization. As an alternative to the external, retrospective perspective provided by, for example, Rita Felski in The Limits of Critique, it draws on the work of Martin Heidegger, Pierre Macherey, and the poet-critic J. H. Prynne to offer a conjunctural approach.

AbstractExploration of structure-property relationships as a function of dopant concentration is commonly based on mean field theories for solid solutions. However, such theories that work well for semiconductors tend to fail in materials with strong correlations, either in electronic behavior or chemical segregation. In these cases, the details of atomic arrangements are generally not explored and analyzed. The knowledge of the generative physics and chemistry of the material can obviate this problem, since defect configuration libraries as stochastic representation of atomic level structures can be generated, or parameters of mesoscopic thermodynamic models can be derived. To obtain such information for improved predictions, we use data from atomically resolved microscopic images that visualize complex structural correlations within the system and translate them into statistical mechanical models of structure formation. Given the significant uncertainties about the microscopic aspects of the material’s processing history along with the limited number of available images, we combine model optimization techniques with the principles of statistical hypothesis testing. We demonstrate the approach on data from a series of atomically-resolved scanning transmission electron microscopy images of MoxRe1-xS2 at varying ratios of Mo/Re stoichiometries, for which we propose an effective interaction model that is then used to generate atomic configurations and make testable predictions at a range of concentrations and formation temperatures.

AbstractIn this paper, we study strong solutions of some non-local difference–differential equations linked to a class of birth–death processes arising as discrete approximations of Pearson diffusions by means of a spectral decomposition in terms of orthogonal polynomials and eigenfunctions of some non-local derivatives. Moreover, we give a stochastic representation of such solutions in terms of time-changed birth–death processes and study their invariant and their limit distribution. Finally, we describe the correlation structure of the aforementioned time-changed birth–death processes.

Specifying a proper statistical model to represent asymmetric lifetime data with high kurtosis is an open problem. In this paper, the three-parameter, modified, slashed, generalized Rayleigh family of distributions is proposed. Its structural properties are studied: stochastic representation, probability density function, hazard rate function, moments and estimation of parameters via maximum likelihood methods. As merits of our proposal, we highlight as particular cases a plethora of lifetime models, such as Rayleigh, Maxwell, half-normal and chi-square, among others, which are able to accommodate heavy tails. A simulation study and applications to real data sets are included to illustrate the use of our results.

What is the impact of copyright(and neighbouring rights)on art— on the conditions for artistic production as well as on other art-related practices in modern societies like trading, conserving, exhibiting, performing, reproducing and distributing works of art or reproductions thereof in various media? And what is the particular relevance of art (and of aesthetic concepts, or theories of art) for copyright? Why should the dogmatics of copyright be concerned with aesthetics at all, and what function do aesthetic concepts fulfil in the conceptual structure of copyright and in the context of its legitimization?
