description: Доклад посвящен актуальной проблеме современного гуманитарного знания: взаимосвязи и разграничению предметных полей риторики и филологии. Обращение к диалогу двух древнейших связанных с языковой деятельностью дисциплин обусловлено возрождением риторики на новых социальных, теоретических и философских основаниях, а также с ее претензией выступать методологией исследования не только языкознания, но и гуманитарных наук в целом, и тем самым отвечать за характер формирования современной коммуникации и общественного сознания. Автор занимает следующую позицию: поместив риторику между социальной технологией и теорией общества, мы можем обнаружить, что риторика выступает не только руководством по организации эффективной коммуникации или теорией языкового воздействия на аудиторию, но и в качестве метода познания действительности и выявления критериев разумности совершаемых действий, а это, в свою очередь, открывает новые перспективы межпредметного взаимодействия риторики и филологии.

description: Timed automata (TA) have been widely adopted as a suitable formalism to model time-critical systems. Furthermore, contemporary model-checking tools allow the designer to check whether a TA complies with a system specification. However, the exact timing constants are often uncertain during the design phase. Consequently, the designer is often able to build a TA with a correct structure, however, the timing constants need to be tuned to satisfy the specification. Moreover, even if the TA initially satisfies the specification, it can be the case that just a slight perturbation during the implementation causes a violation of the specification. Unfortunately, model-checking tools are usually not able to provide any reasonable guidance on how to fix the model in such situations. In this paper, we propose several concepts and techniques to cope with the above mentioned design phase issues when dealing with reachability and safety specifications.

description: Biological membranes are host to proteins and molecules which may form domain-like structures resulting in spatially-varying material properties. Vesicles with such heterogeneous membranes can exhibit intricate shapes at equilibrium and rich dynamics when placed into a flow. Under the assumption of small deformations we develop a reduced order model to describe the fluid-structure interaction between a viscous background shear flow and an inextensible membrane in two dimensions with spatially varying bending stiffness and spontaneous curvature. Material property variations of a critical magnitude, relative to the flow rate and internal/external viscosity contrast, can set off a qualitative change in the vesicle dynamics. A membrane of nearly constant bending stiffness or spontaneous curvature undergoes a small amplitude swinging motion (which includes tangential tank-treading), while for large enough material variations the dynamics pass through a regime featuring tumbling and periodic phase-lagging of the membrane material, and ultimately for very large material variation to a rigid body tumbling behavior. Distinct differences are found for even and odd spatial modes of domain distribution. Full numerical simulations are used to probe the theoretical predictions, which appear valid even when studying substantially deformed membranes.

description: Right now, we have not enough knowledge to determine the hadron distribution amplitudes (DAs) which are universal physical quantities in the high energy processes involving hadron for applying pQCD to exclusive processes. Even for the simplest pion, one can't discriminate from different DA models. Inversely, one expects that processes involving pion can in principle provide strong constraints on the pion DA. For example, the pion-photon transition form factor (TFF) can get accurate information of the pion wave function or DA, due to the single pion in this process. However, the data from Belle and BABAR have a big difference on TFF in high $Q^2$ regions, at present, they are helpless for determining the pion DA. At the present paper, we think it is still possible to determine the pion DA as long as we perform a combined analysis of the most existing data of the processes involving pion such as $π\to μ\barν$, $π^0 \to γγ$, $B\to πl ν$, $D \to πl ν$, and etc. Based on the revised light-cone harmonic oscillator model, a convenient DA model has been suggested, whose parameter $B$ which dominates its longitudinal behavior for $ϕ_π(x,μ^2)$ can be determined in a definite range by those processes. A light-cone sum rule analysis of the semi-leptonic processes $B \to πl ν$ and $D \to πl ν$ leads to a narrow region $B = [0.01,0.14]$, which indicate a slight deviation from the asymptotic DA. Then, one can predict the behavior of the pion-photon TFF in high $Q^2$ regions which can be tested in the future experiments. Following this way it provides the possibility that the pion DA will be determined by the global fit finally.

description: Tuberculosis, caused by Mycobacterium tuberculosis (Mtb), is the infectious disease responsible for the highest number of deaths worldwide. Herein, 22 new N-oxide-containing compounds were synthesized followed by in vitro and in vivo evaluation of their antitubercular potential against Mtb. Compound 8 was found to be the most promising compound, with MIC90 values of 1.10 and 6.62 μM against active and nonreplicating Mtb, respectively. Additionally, we carried out in vivo experiments to confirm the safety and efficacy of compound 8; the compound was found to be orally bioavailable and highly effective, leading to a reduction of Mtb to undetectable levels in a mouse model of infection. Microarray-based initial studies on the mechanism of action suggest that compound 8 blocks translation. Altogether, these results indicate that benzofuroxan derivative 8 is a promising lead compound for the development of a novel chemical class of antitubercular drugs.

description: Edge-coloured directed graphs provide an essential structure for modelling and analysis of complex systems arising in many scientific disciplines (e.g. feature-oriented systems, gene regulatory networks, etc.). One of the fundamental problems for edge-coloured graphs is the detection of strongly connected components, or SCCs. The size of edge-coloured graphs appearing in practice can be enormous both in the number of vertices and colours. The large number of vertices prevents us from analysing such graphs using explicit SCC detection algorithms, such as Tarjan's, which motivates the use of a symbolic approach. However, the large number of colours also renders existing symbolic SCC detection algorithms impractical. This paper proposes a novel algorithm that symbolically computes all the monochromatic strongly connected components of an edge-coloured graph. In the worst case, the algorithm performs $O(p \cdot n \cdot log~n)$ symbolic steps, where $p$ is the number of colours and $n$ is the number of vertices. We evaluate the algorithm using an experimental implementation based on binary decision diagrams (BDDs). Specifically, we use our implementation to explore the SCCs of a large collection of coloured graphs (up to $2^{48}$) obtained from Boolean networks -- a modelling framework commonly appearing in systems biology.

description: Down syndrome is caused by trisomy of chromosome 21. To date, a multiplicity of mouse models with Down-syndrome-related features has been developed to understand this complex human chromosomal disorder. These mouse models have been important for determining genotype-phenotype relationships and identification of dosage-sensitive genes involved in the pathophysiology of the condition, and in exploring the impact of the additional chromosome on the whole genome. Mouse models of Down syndrome have also been used to test therapeutic strategies. Here, we provide an overview of research in the last 15 years dedicated to the development and application of rodent models for Down syndrome. We also speculate on possible and probable future directions of research in this fast-moving field. As our understanding of the syndrome improves and genome engineering technologies evolve, it is necessary to coordinate efforts to make all Down syndrome models available to the community, to test therapeutics in models that replicate the whole trisomy and design new animal models to promote further discovery of potential therapeutic targets.

description: We study the canonical weak distributive law $δ$ of the powerset monad over the semimodule monad for a certain class of semirings containing, in particular, positive semifields. For this subclass we characterise $δ$ as a convex closure in the free semimodule of a set. Using the abstract theory of weak distributive laws, we compose the powerset and the semimodule monads via $δ$, obtaining the monad of convex subsets of the free semimodule.

description: The $Φ^4_3$ equation is a singular stochastic PDE with important applications in mathematical physics. Its solution usually requires advanced mathematical theories like regularity structures or paracontrolled distributions, and even local well-posedness is highly nontrivial. Here we propose a multiplicative transformation to reduce the periodic $Φ^4_3$ equation to a well-posed random PDE. This leads to a simple and elementary proof of global well-posedness, which only relies on Schauder estimates, the maximum principle, and basic estimates for paraproducts, and in particular does not need regularity structures or paracontrolled distributions.

description: It is well-known that the antipode $S$ of a commutative or cocommutative Hopf algebra satisfies $S^{2}=\operatorname*{id}$ (where $S^{2}=S\circ S$). Recently, similar results have been obtained by Aguiar, Lauve and Mahajan for connected graded Hopf algebras: Namely, if $H$ is a connected graded Hopf algebra with grading $H=\bigoplus_{n\geq0}H_n$, then each positive integer $n$ satisfies $\left( \operatorname*{id}-S^2\right)^n \left( H_n\right) =0$ and (even stronger) \[ \left( \left( \operatorname{id}+S\right) \circ\left( \operatorname{id}-S^2\right)^{n-1}\right) \left( H_n\right) = 0. \] For some specific $H$'s such as the Malvenuto--Reutenauer Hopf algebra $\operatorname{FQSym}$, the exponents can be lowered. In this note, we generalize these results in several directions: We replace the base field by a commutative ring, replace the Hopf algebra by a coalgebra (actually, a slightly more general object, with no coassociativity required), and replace both $\operatorname{id}$ and $S^2$ by "coalgebra homomorphisms" (of sorts). Specializing back to connected graded Hopf algebras, we show that the exponent $n$ in the identity $\left( \operatorname{id}-S^2\right) ^n \left( H_n\right) =0$ can be lowered to $n-1$ (for $n>1$) if and only if $\left( \operatorname{id} - S^2\right) \left( H_2\right) =0$. (A sufficient condition for this is that every pair of elements of $H_1$ commutes; this is satisfied, e.g., for $\operatorname{FQSym}$.)

description: Weighted automata are a generalization of nondeterministic automata that associate a weight drawn from a semiring $K$ with every transition and every state. Their behaviours can be formalized either as weighted language equivalence or weighted bisimulation. In this paper we explore the properties of weighted automata in the framework of coalgebras over (i) the category $\mathsf{SMod}$ of semimodules over a semiring $K$ and $K$-linear maps, and (ii) the category $\mathsf{Set}$ of sets and maps. We show that the behavioural equivalences defined by the corresponding final coalgebras in these two cases characterize weighted language equivalence and weighted bisimulation, respectively. These results extend earlier work by Bonchi et al. using the category $\mathsf{Vect}$ of vector spaces and linear maps as the underlying model for weighted automata with weights drawn from a field $K$. The key step in our work is generalizing the notions of linear relation and linear bisimulation of Boreale from vector spaces to semimodules using the concept of the kernel of a $K$-linear map in the sense of universal algebra. We also provide an abstract procedure for forward partition refinement for computing weighted language equivalence. Since for weighted automata defined over semirings the problem is undecidable in general, it is guaranteed to halt only in special cases. We provide sufficient conditions for the termination of our procedure. Although the results are similar to those of Bonchi et al., many of our proofs are new, especially those about the coalgebra in $\mathsf{SMod}$ characterizing weighted language equivalence.

description: A current-carrying resonant nanoscale device, simulated by non-adiabatic molecular dynamics, exhibits sharp activation of non-conservative current-induced forces with bias. The result, above the critical bias, is generalized rotational atomic motion with a large gain in kinetic energy. The activation exploits sharp features in the electronic structure, and constitutes, in effect, an ignition key for atomic-scale motors. A controlling factor for the effect is the non-equilibrium dynamical response matrix for small-amplitude atomic motion under current. This matrix can be found from the steady-state electronic structure by a simpler static calculation, providing a way to detect the likely appearance, or otherwise, of non-conservative dynamics, in advance of real-time modelling.

description: Wigner's friend thought experiment is intended to reveal the inherent tension between unitary evolution and measurement collapse. On the basis of Wigner's friend experiment, Brukner derives a no-go theorem for observer-independent facts. We construct an extended Wigner's friend scenario including three laboratories, namely, Alice's laboratory, Bob's laboratory and Charlie's laboratory, where Alice, Bob and Charlie are standing outside the laboratories while their friends are placed inside their own laboratories. We consider quantum simulation via Q\# quantum programming and also realize the primary quantum circuits using IBM quantum computers. Then, we calculate the probabilities and corresponding statistical uncertainties. It has been shown that the results of quantum simulation are clearly consistent with theoretical values, while it has a slightly higher error rates for the experimental results of quantum computers mainly because of a series of quantum gates, especially CNOT gates.

Calibration and Study of the Contoured Nozzle of the T5 Free-Piston Hypervelocity Shock Tunnel
Creators: name: Rousset, Bernard
Publisher: name: California Institute of Technology
Year: 1995
Subjects: Aeronautics

description: A pitot pressure survey of the contoured nozzle of the T5 shock tunnel was performed over a wide range of reservoir conditions and in the region of the exit plane of the nozzle. A rake of thirteen pitot probes was used for this purpose. The survey includes an investigation of the repeatability of the facility and an analysis of the accuracy of the measurements. The features of the pitot pressure distribution across the exit plane are a pronounced minimum near but not exactly on the centerline, and a pronounced drop near the nozzle wall. The concave profile may be quantified in terms of the curvature of the pitot pressure distribution, which increases markedly as the enthalpy is decreased and as the area ratio is increased. The normalized value of the minimum pitot pressure is found to be independent of the reservoir enthalpy, in contrast to the behavior obtained by numerical computation of inviscid flows. The results of this survey show clearly, that the use of a contoured nozzle should be restricted to conditions very close to the design condition. Since flexibility in the reservoir enthalpy and pressure, as well as area ratio, is an important feature of a shock tunnel, the results of this survey strongly suggest the use of a conical nozzle.

description: Following a recently considered generalisation of linear equations to unordered-data vectors and to ordered-data vectors, we perform a further generalisation to data vectors that are functions from k-element subsets of the unordered-data set to vectors of integer numbers. These generalised equations naturally appear in the analysis of vector addition systems (or Petri nets) extended so that each token carries a set of unordered data. We show that nonnegative-integer solvability of linear equations is in nondeterministic exponential time while integer solvability is in polynomial time.

description: In the current paper, the characteristic factor  is extracted from the analytical solution of the bending moment for a rectangular strainhardening beam first. Thereafter, the characteristic factor β is transplanted into the
previously proposed assessment of the critical buckling strain for rigid-perfectly plastic
bending pipe by analogy method, thus an extended expression of the critical buckling strain
for a pipe plastic bending including strain-hardening effect is developed. Moreover, available test data is employed to
check the suitability of the extended expression. The results show that the extended
expression is reasonable to reveal the effect of Hollomon type strain-hardening behavior on
the critical buckling strain of pipe plastic bending.

description: We investigate the problem of parameter synthesis for time Petri nets with a cost variable that evolves both continuously with time, and discretely when firing transitions. More precisely, parameters are rational symbolic constants used for time constraints on the firing of transitions and we want to synthesise all their values such that some marking is reachable, with a cost that is either minimal or simply less than a given bound. We first prove that the mere existence of values for the parameters such that the latter property holds is undecidable. We nonetheless provide symbolic semi-algorithms for the two synthesis problems and we prove them both sound and complete when they terminate. We also show how to modify them for the case when parameter values are integers. Finally, we prove that these modified versions terminate if parameters are bounded. While this is to be expected since there are now only a finite number of possible parameter values, our algorithms are symbolic and thus avoid an explicit enumeration of all those values. Furthermore, the results are symbolic constraints representing finite unions of convex polyhedra that are easily amenable to further analysis through linear programming. We finally report on the implementation of the approach in Romeo, a software tool for the analysis of time Petri nets.

description: Two-dimensional transition metal dichalcogenide (2D TMD) crystals are versatile platforms for realizing emergent optoelectronic devices. However, the ability to produce large-area 2D TMDs with spatial homogeneity and to accomplish broadband photodetection by tuning the operating wavelengths in photodetectors are two paramount prerequisites for practical applications of 2D TMD-based photodetectors. Here, we demonstrated all-solution-processed broadband photodetectors based on the wafer-scale perovskite quantum dots (PQDs)/MoS2 through light management via the monochromatization effect of the PQDs. The photodetectors exhibited broadband photodetection behavior that retained high photocurrents over a wide spectral range (254, 365, and 532 nm) by enhancing the photoresponse in the UV region through light management via the monochromatization effect of the PQDs. This intriguing strategy was proven with (i) electrical isolation realized by inserting an Al2O3 insulator between the PQDs and MoS2 and (ii) alteration of the PQD density. The rational nanohybrid-based photodetectors also exhibited superb air stability and exceptional bending durability.

The formalism is based on Dirac reduction applied to the $N+1$ periodic dressing chain with the odd number $N+1$ for which the Hamiltonian formalism is well known. The Hamilton dressing chain equations in the $N$ even case depend explicitly on a pair of conjugated Dirac constraints and are equivalent to $A^{(1)}_{N-1}$ invariant symmetric Painlevé equations.

Publisher: name: Technological University Dublin

description: Cycling as a mode of transport offers many benefits including a cheap, cost effective, healthy, fast, mainly congestion free and environmentally friendly means of getting to and from places of employment and education. Given the central location of Technological University Dublin campus buildings this would seem an ideal option for its third level students, but on the contrary, a DIT online travel survey conducted in March 2014 found that only 7% of students chose cycling as their primary mode of transport. Concerns about cyclist safety were a major factor cited by students who chose alternative modes of transport. Based on this feedback, DIT BSc Spatial Planning and Environmental management students undertook a study to evaluate the safety of cycling in Dublin City for DIT students As DIT campuses are located throughout Dublin City, the extent of the study area included all of the local areas managed by Dublin City Council. Historical cyclist collision data for years 2006 to 2012 was provided by the Road Safety Authority (RSA) and used with visualisation cluster analysis tools available in Geographical Information Systems (GIS) technology to identify spatio-temporal hot spot areas more susceptible to cyclist collisions. Based on preliminary results focus was placed on collisions that had occurred between small motorised vehicle and pedal cyclist, with emphasis on roads with on street cycle lanes as these were identified as being major contributors for a large percentage of cycle collisions during the study period.

Given a connected simple graph $G$ that is not isomorphic to a path, a cycle, or a $K_{1,3}$, let $δ(G)$ denote the minimum degree of $G$, let $h_s(G)$ denote the smallest integer $i$ such that the iterated line graph $L^{i}(G)$ is $s$-Hamiltonian, and let $\ell(G)$ denote the length of the longest non-closed path $P$ in which all internal vertices have degree 2 such that $P$ is not both of length 2 and in a $K_3$. For a simple graph $G$, we establish better upper bounds for $h_s(G)$ as follows. \begin{equation*} h_s(G)\le \left\{ \begin{aligned} & \ell(G)+1, &&\mbox{ if }δ(G)\le 2 \mbox{ and }s=0;\\ & \widetilde d(G)+2+\lceil \lg (s+1)\rceil, &&\mbox{ if }δ(G)\le 2 \mbox{ and }s\ge 1;\\ & 2+\left\lceil\lg\frac{s+1}{δ(G)-2}\right\rceil, && \mbox{ if } 3\leδ(G)\le s+2;\\ & 2, &&{\rm otherwise}, \end{aligned} \right. \end{equation*} where $\widetilde d(G)$ is the smallest integer $i$ such that $δ(L^i(G))\ge 3$. Consequently, when $s \ge 6$, this new upper bound for the $s$-hamiltonian index implies that $h_s(G) = o(\ell(G)+s+1)$ as $s \to \infty$. This sharpens the result, $h_s(G)\le\ell(G)+s+1$, obtained by Zhang et al. in [Discrete Math., 308 (2008) 4779-4785].

description: Проблема обусловленности речевого этикета коммуникативными установками и социальной дифференциацией общества рассматривается в диахроническом аспекте. Расширение диапазона этикетных средств происходит обычно в периоды интенсивного развития языка, изменения условий его функционирования, связанных с кардинальными преобразованиями в государственном устройстве и всех сферах жизнедеятельности общества. Исследуются некоторые особенности формирования и функционирования норм речевого этикета в деловом языке XVIII в., роль которого в жизни общества возрастает в связи с реформами Петра I. Затрагивается вопрос о преемственности и новациях в области делового речевого этикета, совершенствование которого происходит в нескольких направлениях, что приводит к преобразованию нормы, выстраиванию шкалы этикетных языковых средств, маркирующих «горизонтальные» и «вертикальные» официально-деловые отношения.

description: For a finite-dimensional simple Lie algebra $\mathfrak{g}$, let $U^+_q(\mathfrak{g})$ be the positive part of the quantized universal enveloping algebra, and $A_q(\mathfrak{g})$ be the quantized algebra of functions. We show that the transition matrix of the PBW bases of $U^+_q(\mathfrak{g})$ coincides with the intertwiner between the irreducible $A_q(\mathfrak{g})$-modules labeled by two different reduced expressions of the longest element of the Weyl group of $\mathfrak{g}$. This generalizes the earlier result by Sergeev on $A_2$ related to the tetrahedron equation and endows a new representation theoretical interpretation with the recent solution to the 3D reflection equation for $C_2$. Our proof is based on a realization of $U^+_q(\mathfrak{g})$ in a quotient ring of $A_q(\mathfrak{g})$.

description: Статья посвящена вопросам изучения лингвистического краеведения, играющего особую роль в учебно-воспитательной работе школы и других учебных заведений. Рассматривается топонимия, представляющая одну из наиболее важных и интересных тем лингвокраеведения. На примере топонимов костромского края, содержащих сведения о языке создавшего их народа, истории, географии, этнографии, показывается значимость использования топонимических материалов на занятиях различного вида. Обращается внимание на то, что топонимы, отражающие все стороны жизни людей, — настоящая национально-культурная ценность. Особенно значимой является «законсервированная» в них информация о своеобразии народной речи, в том числе, что очень важно, той её части, которая со временем по разным причинам подвергается серьёзным изменениям или исчезает. Изучение топонимии развивает интерес не только к географическим названиям, но и к тому, что с ними связано, помогает воспитывать бережное отношение к языковой культуре, патриотизм к родному языку, родному краю.

description: Higgs bosons - the amplitude modes - have been experimentally investigated in condensed matter for many years. An example is superfluid $^3$He-B, where the broken symmetry leads to 4 Goldstone modes and at least 14 Higgs modes, which are characterized by angular momentum quantum number $J$ and parity. Based on the relation $E_{J+}^2+E_{J-}^2=4Δ^2$ for the energy spectrum of these modes, Yoichiro Nambu proposed the general sum rule, which relates masses of Higgs bosons and masses of fermions. If this rule is applicable to Standard Model, one may expect that the observed Higgs boson with mass $M_{{\rm H}1}=125$ GeV has a Nambu partner -- the second Higgs boson with mass $M_{{\rm H}2}=325$ GeV. Together they satisfy the Nambu relation $M_{{\rm H}1}^2 + M_{{\rm H}2}^2 = 4 M_{\rm top}^2$, where $M_{\rm top}$ is the top quark mass. Also the properties of the Higgs modes in superfluid $^3$He-A, where the symmetry breaking is similar to that of the Standard Model, suggest the possible existence of two electrically charged Higgs particles with masses $M_{{\rm H}+}=M_{{\rm H}-}\sim 245$ GeV, which together obey the Nambu rule $M_{{\rm H}+}^2 + M_{{\rm H}-}^2 = 4 M_{\rm top}^2$. A certain excess of events at 325 GeV and at 245 GeV has been reported in 2011, though not confirmed in 2012 experiments. Besides, we consider the particular relativistic model of top - quark condensation that suggests the possibility that two twice degenerated Higgs bosons contribute to the Nambu sum rule. This gives the mass around 210 GeV for the Nambu partner of the 125 GeV Higgs boson. We also discuss the other possible lessons from the condensed matter to Standard Model, such as hidden symmetry, where light Higgs emerges as quasi Nambu-Goldstone mode, and the role of broken time reversal symmetry.

description: Рассматриваются важнейшие свойства словарей и энциклопедий, определяющие их особое место в современном мире. Массовое читательское  внимание к словарям и энциклопедиям показывает их роль в осмыслении синтагматики и парадигматики языка культуры. Словари различных типов отвечают на разнообразные запросы пользователей, при этом выбор словаря, соответствующий конкретным коммуникативно-познавательным задачам, требует особых навыков. Свойства словаря соотносятся с познавательной деятельностью языковой личности. Лексикографическая компетенция рассматривается как одна из важнейших составляющих профессиональной компетенции специалиста, которую следует формировать у студентов, обучающихся по различным программам, но прежде всего, конечно, у студентов-филологов. Результаты проведенного опроса студентов позволили выявить характер прагматических запросов пользователей. В статье приводятся разнообразные виды учебно-исследовательских работ, направленных на формирование лексикографической компетенции студентов: лексикографический портрет слова, лексический анализ фрагментов текста современной литературы, редактирование фрагментов текстов детской литературы.

description: The goal in the area of functions property testing is to determine whether a given black-box Boolean function has a particular given property or is $\varepsilon$-far from having that property. We investigate here several types of properties testing for Boolean functions (identity, correlations and balancedness) using the Deutsch-Jozsa algorithm (for the Deutsch-Jozsa (D-J) problem) and also the amplitude amplification technique. At first, we study here a particular testing problem: namely whether a given Boolean function $f$, of $n$ variables, is identical with a given function $g$ or is $\varepsilon$-far from $g$, where $\varepsilon$ is the parameter. We present a one-sided error quantum algorithm to deal with this problem that has the query complexity $O(\frac{1}{\sqrt{\varepsilon}})$. Moreover, we show that our quantum algorithm is optimal. Afterwards we show that the classical randomized query complexity of this problem is $Θ(\frac{1}{\varepsilon})$. Secondly, we consider the D-J problem from the perspective of functional correlations and let $C(f,g)$ denote the correlation of $f$ and $g$. We propose an exact quantum algorithm for making distinction between $|C(f,g)|=\varepsilon$ and $|C(f,g)|=1$ using six queries, while the classical deterministic query complexity for this problem is $Θ(2^{n})$ queries. Finally, we propose a one-sided error quantum query algorithm for testing whether one Boolean function is balanced versus $\varepsilon$-far balanced using $O(\frac{1}{\varepsilon})$ queries. We also prove here that our quantum algorithm for balancedness testing is optimal. At the same time, for this balancedness testing problem we present a classical randomized algorithm with query complexity of $O(1/\varepsilon^{2})$. Also this randomized algorithm is optimal. Besides, we link the problems considered here together and generalize them to the general case.
