The article examines public organizations that functioned and performed state functions in the field of physical culture and sports. Special attention is paid to previously little-studied issues of interaction of the Union of Sports Societies and Organizations of the USSR with state bodies. The source base of the article is the normative legal acts regulating the activities of this organization, as well as documents of the Kaliningrad regional Union of Sports Societies and Organizations that were not previously introduced into scientific circulation. The liberalization of public life during the Thaw period had a significant impact on the position of public organizations in the Soviet political system. The scientific literature of that time actively discussed the issues of involving citizens and public organizations in solving the problems facing the country. One form of such involvement was the transfer of state functions to public organizations. As a result, public organizations were able to make important decisions in a certain segment of the public sphere. The Union of Sports Societies and Organizations of the USSR became a unique organization that completely replaced the state body in the field of physical culture and sports. Based on the material studied, the author comes to the conclusion that the liquidation of the Union of Sports Societies and Organizations of the USSR in 1968 coincided with other processes aimed at curtailing liberal principles in the USSR. Almost 10 years of activity of this organization have shown that the transfer of state functions into the hands of the public is indeed possible.

A comparative structural study of two related donor–acceptor pyridine-based BF2 complexes, namely, 3-(dimethylamino)-1,1-difluoro-1H-pyrido[1,2-c][1,3,5,2]oxadiazaborinin-9-ium-1-uide, C8H10BF2N3O (1), and 3-{(1E,3E)-4-[4-(dimethylamino)phenyl]buta-1,3-dien-1-yl}-1,1-difluoro-1H-pyrido[1,2-c][1,3,5,2]oxadiazaborinin-9-ium-1-uide, C18H18BF2N3O (2), containing a dimethylamino group and either the shortest (in 1) or the longest (in 2) charge-transfer path known until now in this family of compounds, is presented. Single-crystal X-ray diffraction analysis supported by computational investigations shed more light on these systems, indicating, among other aspects, the predominance of C—H...F contacts in 1, the formation of antiparallel dimers held together by π–π interactions in both compounds, and the involvement of fused BF2-bearing rings in the charge-transfer process.

In this article we provide a framework for the study of Hecke operators acting on the Bredon (co)homology of an arithmetic discrete group. Our main interest lies in the study of Hecke operators for Bianchi groups. Using the Baum-Connes conjecture, we can transfer computations in Bredon homology to obtain a Hecke action on the $K$-theory of the reduced $C^{*}$-algebra of the group. We show the power of this method giving explicit computations for the group $SL_2(\mathbb{Z}[i])$. In order to carry out these computations we use an Atiyah-Segal type spectral sequence together with the Bredon homology of the classifying space for proper actions., Comment: 26 pages, minor changes.

In this article, we establish an asymptotic estimate on the number of cuspidal automorphic representations of GL 4 ( A Q ) which contribute to the cuspidal cohomology of GL 4 and are obtained from symmetric cube transfer of automorphic representations of GL 2 ( A Q ) of a given weight and with varying level structure. This generalises the recent work of C. Ambi about the similar problem for GL 3 .

In this paper we develop a method to transfer density results for primitive automatic sequences to logarithmic-density results for general automatic sequences. As an application we show that the logarithmic densities of any automatic sequence along squares $(n^2)_{n\geq 0}$ and primes $(p_n)_{n\geq 1}$ exist and are computable. Furthermore, we give for these subsequences a criterion to decide whether the densities exist, in which case they are also computable. In particular in the prime case these densities are all rational. We also deduce from a recent result of the third author and Lema\'nczyk that all subshifts generated by automatic sequences are orthogonal to any bounded multiplicative aperiodic function., Comment: 35 pages. We added an Appendix concerning upper densities of subsequences of automatic sequences

A data-driven procedure is developed to compute the optimal map between two conditional probabilities $$\rho (x|z_{1},\ldots ,z_{L})$$ and $$\mu (y|z_{1},\ldots ,z_{L})$$ , known only through samples and depending on a set of covariates $$z_{l}$$ . The procedure is tested on synthetic data from the ACIC Data Analysis Challenge 2017 and it is applied to non-uniform lightness transfer between images. Exactly solvable examples and simulations are performed to highlight the differences with ordinary optimal transport.

Solution uniqueness requires three such arcs connected via intermediate transfer orbits. Junction conditions provide state vector continuity at junction points. Fuel efficiency is compared with impulsive trajectories.

This study focuses on the development of new synthetic pathways to monosubstituted biguanides from amines. An exhaustive comparison of the conditions and reagents used for biamidine transfer was performed. New reagents were synthesized and optimized conditions for the synthesis of substituted biguanides under mild conditions were developed. Eventually, two high-yielding and straightforward protocols for the transfer of a biamidine group to various amines are proposed and their scope and limitations have been explored. These conditions include: i) a direct chromatography-free procedure and ii) an eco-friendly procedure in water compatible with bioinspired molecules. They are particularly efficient for the demanding conversion of aliphatic amines.

We study the Steklov problem on a subgraph with boundary $(\Omega,B)$ of a polynomial growth Cayley graph $\Gamma$. We prove that for each $k \in \mathbb{N}$, the $k^{\mbox{th}}$ eigenvalue tends to $0$ proportionally to $1/|B|^{\frac{1}{d-1}}$, where $d$ represents the growth rate of $\Gamma$. The method consists in associating a manifold $M$ to $\Gamma$ and a bounded domain $N \subset M$ to a subgraph $(\Omega, B)$ of $\Gamma$. We find upper bounds for the Steklov spectrum of $N$ and transfer these bounds to $(\Omega, B)$ by discretizing $N$ and using comparison Theorems., Comment: 17 pages

In this note we study some properties of an new TAN–G class of trigonometric cumulative distribution functions proposed by Souza, O. Junior, de Brito, Chesneau, Fernandes and Ferreira [1]. We consider also modified families of ”adaptive functions” with ”polynomial variable transfer” with applications to the Antenna–feeder Analysis. We study the ”saturation” - d in the Hausdorff sense for some special cases of this family. The article discusses only model aspects of the possible application that this new family finds in the above area. The models are very sensitive to the coefficients of the polynomial (respectively the number and location of its zeros). This makes these models attractive for simulations. Numerical examples, illustrating our results using CAS MATHEMATICA are given.

We establish sharp large deviation principles for cumulative rewards associated with a discrete-time renewal model, supposing that each renewal involves a broad-sense reward taking values in a real separable Banach space. The framework we consider is the pinning model of polymers, which amounts to a Gibbs change of measure of a classical renewal process and includes it as a special case. We first tackle the problem in a constrained pinning model, where one of the renewals occurs at a given time, by an argument based on convexity and super-additivity. We then transfer the results to the original pinning model by resorting to conditioning.

The main result is as follows: Fix an arbitrary prime $ q $ . A $ q $ -divisible torsion-free (discrete, countable) abelian group $ G $ has a $ \Delta^{0}_{2} $ -presentation if, and only if, its connected Pontryagin–van Kampen Polish dual $ \widehat{G} $ admits a computable complete metrization (in which we do not require the operations to be computable). We use this jump-inversion/duality theorem to transfer the results on the degree spectra of torsion-free abelian groups to the results about the degree spectra of Polish spaces up to homeomorphism. For instance, it follows that for every computable ordinal $ \alpha>1 $ and each $ {\mathbf{a}}>0^{(\alpha)} $ there is a connected compact Polish space having proper $ \alpha^{th} $ jump degree $ {\mathbf{a}} $ (up to homeomorphism). Also, for every computable ordinal $ \beta $ of the form $ 1+\delta+2n+1 $ , where $ \delta $ is zero or is a limit ordinal and $ n\in\omega $ , there is a connected Polish space having an $ X $ -computable copy if and only if $ X $ is $ non $ - $ low_{\beta} $ . In particular, there is a connected Polish space having exactly the $ non $ - $ low_{2} $ complete metrizations. The case when $ \beta=2 $ is an unexpected consequence of the main result of the author’s M.Sc. Thesis written under the supervision of Sergey S. Goncharov.

We prove one direction of a recently posed conjecture by Gan-Gross-Prasad, which predicts the branching laws that govern restriction from p-adic $GL_n$ to $GL_{n-1}$ of irreducible smooth representations within the Arthur-type class. We extend this prediction to the full class of unitarizable representations, by exhibiting a combinatorial relation that must be satisfied for any pair of irreducible representations, in which one appears as a quotient of the restriction of the other. We settle the full conjecture for the cases in which either one of the representations in the pair is generic. The method of proof involves a transfer of the problem, using the Bernstein decomposition and the quantum affine Schur-Weyl duality, into the realm of quantum affine algebras. This restatement of the problem allows for an application of the combined power of a result of Hernandez on cyclic modules together with the Lapid-Minguez criterion from the p-adic setting.

We prove an algebraic canonicity theorem for normal LE-logics of arbitrary signature, in a generalized setting in which the non-lattice connectives are interpreted as operations mapping tuples of elements of the given lattice to closed or open elements of its canonical extension. Interestingly, the syntactic shape of LE-inequalities which guarantees their canonicity in this generalized setting turns out to coincide with the syntactic shape of analytic inductive inequalities, which guarantees LE-inequalities to be equivalently captured by analytic structural rules of a proper display calculus. We show that this canonicity result connects and strengthens a number of recent canonicity results in two different areas: subordination algebras, and transfer results via G\"odel-McKinsey-Tarski translations., Comment: arXiv admin note: text overlap with arXiv:1603.08515, arXiv:1603.08341

This paper studies the class of rings in which every finitely projective ideal is projective (FPP-ring for short). We examine the transfer of this property to various context of commutative ring extensions such as direct product, homomorphic image, trivial ring extension and amalgamation ring. Our work is motivated by an attempt to generate new original classes of rings possessing this property.

The main contribution of Davies and Hoy (Am Econ Rev 85:980–986, 1995) was a “necessary and sufficient” condition for comparing inequality between income distributions according to the principle of transfer sensitivity (PTS). Chiu (Soc Choice Welf 28:375–399, 2007) showed that although the condition is sufficient, it is not necessary. In this paper, we provide the correct necessary and sufficient condition, and demonstrate with a simple example how the corrected condition allows for more pairs of distributions to be ranked by PTS. The correction clarifies the connection between Lorenz curve comparisons and inequality rankings when the curves intersect.

Given a partial order Q , its semiorder dimension is the smallest number of semiorders whose intersection is Q . When we look at the class of partial orders of fixed semiorder dimension k , no characterization is known, even in the case k = 2 . In this paper, we give a characterization of the class of interval orders with semiorder dimension two. It follows from our results that partial orders that are interval orders with semiorder dimension two can be recognized efficiently. As our characterization makes use of a certain substructure, we also discuss the possibility of a forbidden suborder characterization. We give a partial answer to this question by listing all forbidden suborders for a special case. We further transfer our characterization result to the class of interval graphs that induce orders with semiorder dimension two.

Properties of 0+ excited states generated by pairing and quadrupole-quadrupole forces in some rare-earth isotopes are investigated. Energies of the 0+ states, probabilities of the E(0) and E(2) transitions, Rasmussen parameters X, and effective cross sections of two-nucleon transfer reactions have been calculated taking into account mixing of the excited states with different Kπ values. The contribution of mixing of the excited states underestimates values of the calculated physical quantities.

As an application, we use those prime filters and maximal filters to construct the prime and maximal spectras of EQ-algebras. In another application, in order to transfer the spectra of EQ-algebras to the spectra of bounded distributive lattices, we study the reticulation of EQ-algebras.

Laser flash photolysis was used to investigate the photoinduced reactions of excited triplet bioquinone molecule duroquinone (DQ) with tryptophan (Trp) and tyrosine (Tyr) in acetonitrile-water (MeCN-H \begin{document}$_2$\end{document} O) and ethylene glycol-water (EG-H \begin{document}$_2$\end{document} O) solutions. The reaction mechanisms were analyzed and the reaction rate constants were measured based on Stern-Volmer equation. The H-atom transfer reaction from Trp (Tyr) to \begin{document}$^3$\end{document} DQ \begin{document}$^*$\end{document} is dominant after the formation of \begin{document}$^3$\end{document} DQ \begin{document}$^*$\end{document} during the laser photolysis. For DQ and Trp in MeCN-H \begin{document}$_2$\end{document} O and EG-H \begin{document}$_2$\end{document} O solutions, \begin{document}$^3$\end{document} DQ \begin{document}$^*$\end{document} captures H-atom from Trp to generate duroquinone neutral radical DQH \begin{document}$^\bullet$\end{document} , carbon-centered tryptophan neutral radical Trp \begin{document}$^\bullet$\end{document} /NH and nitrogen-centered tryptophan neutral radical Trp/N \begin{document}$^\bullet$\end{document} . For DQ and Tyr in MeCN-H \begin{document}$_2$\end{document} O and EG-H \begin{document}$_2$\end{document} O solutions, \begin{document}$^3$\end{document} DQ \begin{document}$^*$\end{document} captures H-atom from Tyr to generate duroquinone neutral radical DQH \begin{document}$^\bullet$\end{document} and tyrosine neutral radical Tyr/O \begin{document}$^\bullet$\end{document} . The H-atom transfer reaction rate constant of \begin{document}$^3$\end{document} DQ \begin{document}$^*$\end{document} with Trp (Tyr) is on the level of 10 \begin{document}$^9$\end{document} L \begin{document}$\cdot$\end{document} mol \begin{document}$^{-1}$\end{document} \begin{document}$\cdot$\end{document} s \begin{document}$^{-1}$\end{document} , nearly controlled by diffusion. The reaction rate constant of \begin{document}$^3$\end{document} DQ \begin{document}$^*$\end{document} with Trp (Tyr) in MeCN/H \begin{document}$_2$\end{document} O solution is larger than that in EG/H \begin{document}$_2$\end{document} O solution, which agrees with Stokes-Einstein relationship qualitatively.

Elastic and inelastic scattering of α-particles by 9Be nuclei have been analyzed with different incident energies. Optical model parameters (OMPs) of elastic scattering of α-particles by 9Be were obtained on different energies. The Elastic scattering, inelastic scattering and transfer reaction using Coupled Reaction Channel (CRC) method were obtained using Fresco Code. The effect of involving CRC calculations on the differential cross section analysis has been examined. The transfer reaction of (5He) was studied in reaction 9Be(α,9Be)α. spectroscopic factor of 9Be as α+5He configuration was derived from experimental data. Also investigated is the effect of coupling to the excited states 1/2+ and 5/2- of 9Be, and its effect on elastic scattering results. Static deformation has been extracted for 9Be nuclei. The theoretical calculations have been done by codes have a good agreement with experimental data obtained from literature. One step of 5He transfer was sufficient to solve the oscillations in the middle angles of the differential cross section.

The experimental angular distributions for 20Ne + 16O elastic transfer are reanalyzed using different forms of both phenomenological and semi-microscopic potentials. The significant increase in the cross-sections at the backward hemisphere, due to the contribution of α-cluster transfer, is investigated using the distorted wave Born approximation (DWBA) method. The spectroscopic amplitude (SA) for the configuration 20Ne → 16O + α at the different concerned energies is extracted. The agreement between the experimental data and theoretical calculations using the two approaches is reasonably good.

The purpose of this research was to achieve visual simulation of circular weft-knitted transfer-jacquard fabric based on a computer-aided design platform. The corresponding mathematical models were established according to pattern presentations after analyzing the structural characteristics of this kind of stitch. To determine the spatial geometry of the loops, eight-point models were built, especially the introduced multi-course loop model. By comparing the influence of four usual lights on stereoscopic sense, directional light was selected to establish an illumination model. Based on these models and matrix operations, spatial positions of different loop types in the intermesh structure were confirmed by coordinate mapping. The simulation effects of three important parameters of yarn spline rendering were analyzed and discussed, so as to choose the most reasonable data. Integrated with a transfer-jacquard design program, the approach realized three-dimensional structural simulation of circular knitting transfer-jacquard fabric with a naturalistic visual impression which can shorten the proofing process and even inspire the design potential of developers.

We give an explicit computation of the ring structure in wrapped Floer homology of a class of real Lagrangians in $A_k$-type Milnor fibers. In the $A_k$-type plumbing description, those Lagrangians correspond to the cotangent fibers or the diagonal Lagrangians. The main ingredient of the computation is to apply a version of the Seidel representation. For a technical reason, we first carry out computations in v-shaped wrapped Floer homology, and this in turn gives the desired ring structure via the Viterbo transfer map., 34 pages, 4 figures, accepted for publication in Math.

Dynamic process is an approach to cooperative games, and it can be defined as that which leads the players to a solution for cooperative games. Hwang et al. (2005) adopted Hamiache’s associated game (2001) to provide a dynamic process leading to the Shapley value. In this paper, we propose a dynamic transfer scheme on the basis of the dual similar associated game, to lead to any solution satisfying both the inessential game property and continuity, starting from an arbitrary efficient payoff vector.

Comparison results for Markov processes with respect to function-class-induced (integral) stochastic orders have a long history. The most general results so far for this problem have been obtained based on the theory of evolution systems on Banach spaces. In this paper we transfer the martingale comparison method, known for the comparison of semimartingales to Markovian semimartingales, to general Markov processes. The basic step of this martingale approach is the derivation of the supermartingale property of the linking process, giving a link between the processes to be compared. This property is achieved using the characterization of Markov processes by the associated martingale problem in an essential way. As a result, the martingale comparison method gives a comparison result for Markov processes under a general alternative but related set of regularity conditions compared to the evolution system approach.

In this article, we study some properties of random regular expressions of size [Formula: see text], when the cardinality of the alphabet also depends on [Formula: see text]. For this, we revisit and improve the classical Transfer Theorem from the field of analytic combinatorics. This provides precise estimations for the number of regular expressions, the probability of recognizing the empty word and the expected number of Kleene stars in a random expression. For all these statistics, we show that there is a threshold when the size of the alphabet approaches [Formula: see text], at which point the leading term in the asymptotics starts oscillating.

We investigate the dynamics of quantum coherence of a system consisting of two interacting atoms coupling with a common cavity which is filled with a nonlinear Kerr-like medium, in the presence of intrinsic decoherence. It is shown that the stationary quantum coherence can arise in the system as the time approach to infinite. In particular, the amount of stationary quantum coherence can be enhanced by adjusting the Kerr interaction and dipole-dipole interaction. Furthermore, we also explore the influence of Kerr interaction and dipole-dipole interaction on the transfer of quantum information by a witness of the trace distance and find that the transferred information and stationary quantum information can be controlled by the Kerr interaction and dipole-dipole interaction.

Sorting (SRT) and matching-to-sample (MTS) tests have measured the formation of arbitrary stimulus classes. This experiment used SRT and MTS tests to document the expansion of class size. Thirty-two participants learned 12 conditional discriminations with a linear series training structure (A➔B➔C➔D➔E). SRT tests documented the formation of 5-member classes by 17 of the participants. Thereafter, 6-member class expansion was implemented by FC training. Nine of these 17 participants showed class expansion when tracked with a sequence of an SRT, MTS, and a final SRT test, and the other 8 showed expansion when tracked with a sequence of MTS and SRT tests. Thus, SRT tests documented class expansion, and the sequence of tests did not influence class expansion. The 15 participants who did not form the 5-member classes learned the baselines for new 3-member classes (A➔B➔C) and formed them as documented by an SRT test. Then, 4-member class expansion was implemented by FB training. Expansion was assessed using the above-mentioned testing sequences. All 15 showed class expansion with 100% correspondence between the SRT and MTS performances. Sorting documented the expansion of arbitrary stimulus classes, while the MTS tests showed that the stimuli also functioned as members of equivalence classes.

The quantum-mechanical model proposed earlier by Skourtis and Nitzan (J. of Chem. Phys. 119, (2003) 6271) to describe a charge transfer in a fragment of artificial DNA molecule has been numerically investigated. The current rationale for the model is carried out and values of its parameters are indicated. Within this model, the description of the transport of a hole carrier in DNA is based on solutions to the time-dependent Schrödinger equation including damping effects. The non-unitary dynamics of the hole carrier is treated by us within the framework of a theory of continuous quantum measurements by the environment in an open quantum system. Results of numerical analysis of the model are in a good agreement with experimental observations and demonstrate two different types of the charged carrier motion, presumably tunneling and incoherent hopping. The main concepts of the theory of decoherence and superselection for open quantum systems and the prospects for their application for further study of various mechanisms of motion of a charged carrier in DNA are briefly discussed.

The implant design is one of the main factors in implant stability because it affects the contact area between the bone and the implant surface and the stress-strain distribution at the bone-implant interface. In this study, the effect of different groove geometries on stress-strain distributions in small-diameter conical implants is investigated using the finite element method (FEM). Four different thread models (rectangular, buttressed, reverse buttressed, and symmetrical profile) are created by changing the groove geometry on the one-piece implants, and the obtained results are compared. The stress shielding effect is investigated through the dimensionless numbers that characterize the load-sharing between the bone-implant. It is determined that the lowest stress distribution is observed with rectangular profiled groove geometry. Besides, it is obtained that the buttressed groove geometry minimizes the stress effects transmitted to the periphery of the implant. The symmetrical profiles had better performance than rectangular profiles in stress transfer.
