A scalable method for mining graph patterns stable under subsampling is proposed. The existing subsample stability and robustness measures are not antimonotonic according to definitions known so far. We study a broader notion of antimonotonicity for graph patterns, so that measures of subsample stability become antimonotonic. Then we propose gSOFIA for mining the most subsample-stable graph patterns. The experiments on numerous graph datasets show that gSOFIA is very efficient for discovering subsample-stable graph patterns.
The article considers the content of the concept ‘terpimost’ (‘tolerance’ and ‘toleration’) according to its usage fixed in the National Corpus of the Russian language. In its most usual meanings terpimost’ flourishes, develops, pacifies, gives the freedom of choice, plays a role, dominates, attracts etc. Terpimost’ is manifested towards hardships (when something unpleasant is endured), someone else’s opinion, position, conduct, flaws of others; in these cases terpimost’ is viewed as a virtue. In the axiological sense, it is selective since it depends on certain regulatory mechanisms and rules which are established in every sociocultural environment. Terpimost’ in the Russian language image of the world is metaphorized as a plant which blooms, as a Lordship that rules and grants a right, as a power that reigns, as a wave that propagates, as a benefit that attracts.
This paper deals with the Semantics/Pragmatics distinction in a contrastive ethnolinguistic aspect. I argue for the validity of this distinction based on cross-linguistic data. My claim is that the specificity of the so-called language key words [Wierzbicka 1990:15-17] - linguospecific items particularly representative of a given language speakersђ mentality - is due to pragmatic rather than semantic peculiarities. These pragmatic peculiarities distinguish the key words both from their synonyms within the same language and their counterparts in other languages. The languages under discussion are Russian and English, analyzed within a combined frame of Integral Language Description model [Apresjan 1995:8-238] and Wierzbickaђs ethnolinguistic approach.
Uncontroversially, the meaning of first and second person pronouns and “imposters”, i.e. expressions like yours truly, (Collins and Postal 2012), should be indexical (Kaplan 1977/1989, Stalnaker 1970), but how exactly this indexicality is achieved has been a matter of some debate. While not settling the debate, this paper aims to show that there is no single way to become a person indexical. Natural language allows for at least three different represen- tations leading to person indexicality. Evidence for this comes from sentences involving imposters and pronouns coreferent with or bound by them. Partic- ularly telling are cases of variation between third and non-third pronouns in sentences with imposters, first discussed by Collins and Postal. Constraints on this variation support the view that it is not adequate from either an empirical or an explanatory perspective to treat all person indexicals uniformly.
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.

This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
