This paper investigates the impact of query topology on the difficulty of answering conjunctive queries in the presence of OWL 2 QL ontologies. Our first contribution is to clarify the worst-case size of positive existential (PE), non-recursive Data log (NDL), and first-order (FO) rewritings for various classes of tree-like conjunctive queries, ranging from linear queries to bounded tree width queries. Perhaps our most surprising result is a super polynomial lower bound on the size of PE-rewritings that holds already for linear queries and ontologies of depth 2. More positively, we show that polynomial-size NDL-rewritings always exist for tree-shaped queries with a bounded number of leaves (and arbitrary ontologies), and for bounded tree width queries paired with bounded depth ontologies. For FO-rewritings, we equate the existence of polysize rewritings with well-known problems in Boolean circuit complexity. As our second contribution, we analyze the computational complexity of query answering and establish tractability results (either NL-or LOGCFL-completeness) for a range of query-ontology pairs. Combining our new results with those from the literature yields a complete picture of the succinctness and complexity landscapes for the considered classes of queries and ontologies.

An array DBMS streamlines large N-d array management. A large portion of such arrays originates from the geospatial domain. The arrays often natively come as raster files while standalone command line tools are one of the most popular ways for processing these files. Decades of development and feedback resulted in numerous feature-rich, elaborate, free and quality-assured tools optimized mostly for a single machine. ChronosDB partially delegates in situ data processing to such tools and offers a formal N-d array data model to abstract from the files and the tools. ChronosDB readily provides a rich collection of array operations at scale and outperforms SciDB by up to 75× on average.
1. Description of the problem. Instrumental analysis makes it possible to find the arguments of adjudication on the bounders and structure of corpus delicti, its correlation to criminal and filling-up legislation. 2. Initial theses. Corpus delicti is regarded as that expressed in criminal law doctrine result of reorganization of orders of criminal law into other practically necessary form. That happens in the process of theory and practical experience accumulation. The construction of corpus delicti is transformed for practical needs, textually expressed system of features, regulated by criminal law and characterizing deeds as a crime of a definite type. Correlation of construction of corpus delicti with law and doctrine. Corpus delicti, its algorithm. Transition from law regulations to corpus delicti can be done: 1) prog-nostically; 2) within constant analysis of law; 3) in the process of law application. 3. Stages of instrumental building of corpus delicti: prognostic, doctrinal, law applicatory. Instrumental approach to corpus delicti includes within each stage: 1) based on criminal law decision of classification of corpus delicti and its borders; 2) objective description of a factual model; 3) acception of meaning correlated with legal notions and constructions; 4) choice of the construction of the corpus delicti and disposal of characteristics; 5) verification of legitimacy, necessity and adequacy of foundation. 4. Instrumental analysis of disputable questions of understanding and application of constructions of corpus delicti. A. Functions and purposes of application of construction of corpus delicti. Functions of corpus delicti: a) modeling; b) communicative; c) identificatory; d) technological. B. Contents of corpus delicti. Contents of corpus delicti as it is traditionally regarded does not correspond to indications of crime, does not characterize features of social danger; sign of danger of penalty also does go into corpus delicti. Two variants are proposed for the discussion: widening of the borders of corpus delicti by means of introduction of signs of social danger and signs, defining individualization of penalty and to limitate corpus delicti by characteristic of criminally punished act, separating it from contents of guilt and contents of social danger. C. Structure of corpus delicti. There are two problems: division of elements of crime seems to be extremely harsh and inadequate - it is expedient to include signs of special and time limits of act, causal links, crossing signs of objective and subjective sides, first of all consequences and an object of crime, into the structure of corpus delicti. Forms of committing a criminally punished act is a crime commitment in complicity, ideal system, not finished crime.
The article analyzes the legislation in force as well as the legal opinions that exist with respect to the legal treatment of public services, legal powers, and administrative functions of the executive authority. The author notes the ambiguous and contradictory nature of legal regulation in the sphere of public services and the absence of a uniform approach to understanding them in the Russian law theory. The existing legislation defines public services through administrative functions or works or activities or legal powers. This is unacceptable from the standpoint of legal writing as clarity and unambiguousness of terminology adopted in legislation is one of the most important factors of its efficiency and of the quality of state governing. The author concludes that public services, legal powers, and administrative functions are widely different terms that denote different legal phenomena. "Legal powers" and administrative functions are an institution of public law, whereas "public services" belong to the domain of private law.

Psychology is a discipline standing at the crossroads of hard and social sciences. Some of psychology journals are attributed to SCIE in Web of Science database while others to SSCI (and some to both). So it is especially interesting to study bibliometric characteristics of psychology journals. We study not the citedness itself (IF etc.) but the citation distribution across papers within psychology publications. This is, so to say, “indicators of the second order” which measure the digression of the citations received by individual papers from the journal’s average. This also influences the publication strategies of the authors. Some journals guarantee to the author receiving of the mean number of citations while others have much more “All or Nothing” grade when any individual paper may have many cites or not have them at all. We also define four different types of psychology journals and explore their characteristics separately.
We solve a problem about the orthogonal complement of the space spanned by restricted shifts of functions in L^2 [0,1] posed by M.Carlsson and C.Sundberg.
The article is devoted to a particular form of freedom of assembly — the right to counter-demonstrate. The author underlines the value of this right as an element of democratic society, but also acknowledges the risk of violent actions among participants of opposing demonstrations. Due to this risk, the government may adopt adequate measures restricting the right to counter-demonstrate, certain types of which are analyzed in this paper.
Development of standards of international controllability is reviewed in the article. Institutional approach is applied to development of international legal regime of Energy Charter. Definition of controllability is connected to development of international standards of dispute settlement, which are described in the article in detail. In connection with controllability, Russian interest, defense of investment in European Union and ecological investment encouragement, is reviewed in the article.
