Authors: Скляренко Олеся , Акімова Аліна , Свириденко Оксана 
Published: November 2019

Research actuality has determined the necessity to study the peculiarities of contextual realization of the concept ”MACHT” in German communicative and cultural area by means of using the results of free associative experiment and contextual analysis of proverbs and aphorisms that made it possible to find out value preferences and priorities of Germans.
The purpose of the article is to identify psycholinguistic peculiarities of the concept “MACHT” in German communicative and cultural area by comparing the results of contextual analyses of proverbs and aphorisms based on the results of free associative experiment.
To describe the results of linguistic material we used such methods as semantic cognitive concept modeling which allowed us to identify macro models and describe the frame model of the concept “MACHT” organization which we present as a chain-organized structure: the concept “MACHT”, macro frame “MACHT UND GESELLSCHAFT” and subframes “MACHT UND DAS POLITISCHE”, “MACHT UND DAS SOZIALE” “MACHT UND DAS HÄUSLICHE”. To find out the psycholinguistic peculiarities of conceptual realization we have used the methodology of free associative experiment.
The findings of the conducted analysis reveal that the concept “MACHT” is manifested in German communicative and cultural area as the subframes “MACHT UND DAS POLITISCHE”, “MACHT UND DAS SOZIALE” “MACHT UND DAS HÄUSLICHE”, where a typical representative of power is characterized by valuable possibilities to direct other, have respect, prosperity and some social characteristics, such as: medical insurance, social help in case of unemployment, possibility to implement himself/herself into society while having the refuges status or being a single parent, have the right to have holidays and free time, the right for sexual preferences. Valuable marker is very important here as it forms axiological personality marker of self-esteem and reflects in reaction of free associative experiment in nominations and markers of private properties, authority and keeping one’s own face in front of society and lifestyle.
Conclusion. In this way the general prototype of an ideal power subject is seen as an ethnic and cultural carrier of the German linguistic and cultural studies concerning the power subject, its communicative behavior, personal features necessary for successful result of power object, his/her appearance and social state.
Electronic Filing System of Language Innovations in Media: Psycholinguistic Metric
Authors: Шевченко Лариса , Сизонов Дмитро 
Published: November 2019

Objective. The article presents the concept of creating an electronic filing system of language innovations (new vocabulary/phraseology) that updates the material of Ukrainian mass media with great attention to its psycholinguistic and functional-stylistic metric. The complex analysis of the e-filing system, which is based on the dynamics of Ukrainian media communication (2016-2018), is the goal of this study.
Materials & Methods. An innovative author's methodology «10/10: new contexts / new editions» maximally allows to objectify the obtained results and accurately describe them at the relevant time. A special functional-stylistic & psycholinguistic marking allows to evaluate evolutionary processes in language, analyze the degree of axiology of language resource and predict the time of “life” of language innovation in Ukrainian mass consciousness.
Results. Special lexicographic markers are proposed to help: (a) determine the degree of influence of a new unit on mass consciousness; (b) assess typical / non-standard communicative situation of appearance of a unit in media; (c) find out the stylistic potential of language innovation in modern Ukrainian. About 1,000 language innovations (words, phraseologisms, semantically and word-transformed units) are represented in the electronic filing system (see author’s portal «Language Innovation.UA» on newlexua.blogspot.com on the Google-platform), which are lexicographically represented as a serial dictionary «New words and phraseologisms in Ukrainian mass media» (2016-2018). The theory of media psychology has helped to distribute the material in e-filing system according to evaluative (axiological) dominants (see Martin, J.), pointing to neutral, positive or negative word semantics.
Conclusions. The analyzed material allows to assert that updating of the lexical-phraseological fund of the Ukrainian language has an ongoing nature, an explanation of which is found in the interaction of extra- and intralinguistic factors (particularly, the phenomenon of «linguistic trend» in language innovations of the Western world, multiculturalism, expansion of the information space, etc.). The monitoring of contemporary Ukrainian media made it possible to analyze the causes of replication and consolidation of innovative vocabulary/phraseology in mass consciousness.

Bakau merupakan sumber potensi lokal pesisir Kabupaten Karawang, yang diolah menjadi serbuk warna pada implementasi kain tekstil. Pada penelitian ini menyajikan kajian terbaharukan dari pengolahan zat warna alam (ZWA) dari serbuk dengan perlakuan panas dingin dengan variasi komposisi merang dan diuji terhadap pengaruh jenis fiksator terhadap variasi jenis kain (kain katun polos, sutera polos dan katun batik). Metode panas dingin dilakukan dengan merendam serbuk bakau dengan komposisi 100gr/1liter air, ditambahkan dengan variabel komposisi merang yang dibakar (metode panas) 100gr/1liter dan 200 gr/1liter air selama 48 jam. Zat warna alam yang dihasilkan, kemudian diujikan ke variasi jenis kain, dengan perlakuan non fiksator (sebagai pembanding dan kenampakan originalitas warna) dan variasi fiksator (tawas, kapur, dan tunjung). Parameter hasil uji dilakukan terhadapa skala penilaian kualitatif berdasarkan staining scale pada uji pencucian, uji kelunturan dan terik matahari. Pengolahan data kualitatif tersebut menggunakan ANOVA dua arah dengan beda nyata pada taraf uji 5%. Hasil penelitian menunjukkan, pada pengolahan ANOVA dua arah dihasilkan perbedaan yang signifikan antara beda perlakuan komposisi A dan B terhadap ragam penilaian persepsi keberadaan fiksator. Berdasarkan hal tersebut diperoleh kondisi terbaik pada perlakuan komposisi A. Sedangkan pengaruh ragam penilaian terhadap jenis kain, tidak ditemukan perbedaan yang nyata.
The Official Statistical Observation by Form “Report on Issue, Offering and Circulation of Securities”: The Importance for Decision-Making at the Ukrainian Stock Market
Authors: Panteleiev V. P. 
Published: December 2019

Practical aspects of preparation and use of the Official Statistical Observation of Ukrainian enterprises by Form “Report on Issue, Offering and Circulation of Securities” is highlighted from the perspectives of equity formation and transfer of ownership for equity components (shares and other securities). Value characteristics of issue, offering and circulation of issuers’ securities are discussed. It is demonstrated that the above characteristics constitute the information base for the operation of securities market, with the core data being the overall nominal value of securities belonging to the owners. Emphasis is made on the importance of data obtained from the form No 2-Б about issue, offering and circulation of securities for the Ukrainian stock market; data on key transactions on the securities market in 2012–2016 are given.
The classification and terms of the official statistical observation and the peculiarities of preparing the report on issue, offering and circulation of securities by form No 2-Б are discussed. The essential observation parameters are selected as the classification criteria, namely: characteristics of its organization, preparation, subject, respondents, statistical methodology, statistical tools, statistical indicators, etc.
It is stressed that statistical information carriers, e. i. observation forms, were being changed along with transformations in the Ukrainian economy. The evolution of the form No 2-Б for the official statistical observation of Ukrainian enterprises on issue, offering and circulation of securities over 1997–2017 is traced. The change in recording of aspects like bond value, as well as observation status, title, respondents, periodicity, contents of the form sections, etc. are shown.
The information base for the official statistical observation by form No 2-Б is the data from accounting and financial statements of enterprises issuing equity securities. The legal base is provisions and regulations of normative acts on equity, fixed in the statutory documents of an issuer. The information from accounting and financial statements of a joint-stock company on equity transferred to ownership has considerable value, being used for effective company management and for filling and submission of the form No 2-Б. The latter is of great interest for investors engaged in taking investment decisions. Conclusions from the study are made and areas of further studies are outlined.

Authors: Yoshinari Orie , Udani Jay , Moriyama Hiroyoshi , Shiojima Yoshiaki , Chien Xiaoming 
Published: December 2019

Background: Nutraceuticals and functional foods are increasingly being used to help manage hypertension. Treatment with either pumpkin or onion can significantly lower systolic and diastolic blood pressure in animal studies. Traditionally, pumpkin has been used to support healthy blood pressure, glucose tolerance and lipid levels. Onion contains high levels of flavonoids, including quercetin, which decreases blood pressure and promotes restoration of healthy endothelial function. However, human trials on these food sources are limited, and the combined effects of pumpkin and onion have not been examined yet.Objective: We performed an open-label clinical study to evaluate the effects of a proprietary onion-pumpkin extract (OPtain120) on systolic and diastolic blood pressure.Methods: Healthy adults with systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the elevated range of 140-159 and 80-90 mmHg, respectively, were enrolled in this study. Subjects consumed one capsule of onion-pumpkin extract twice daily for 12 weeks. Daily Home Blood Pressure Measurement (HBPM) was taken upon waking and before bed. Office Blood Pressure Measurement (OBPM) was taken in-clinic at Week 0, 6, and 12.Results: 52 subjects were screened and 12 were enrolled in the study, with a total of 10 subjects completing the study. Systolic HBPM taken before bed demonstrated a statistically significant reduction from baseline (147.23 mmHg) to Week 12 (138.14 mmHg), representing a reduction of 9.09 mmHg (6.17%, p=0.021). Diastolic HBPM taken before bed demonstrated a decrease of 4.06 mmHg (4.46%, p=0.085), a significant reduction from baseline (91.07 mmHg) at Week 12 (87.02 mmHg). Non-statistically significant reductions were seen in the early morning Systolic (3.14%) and Diastolic (2.57%) HBPM and in the Systolic (1.36%) OBPM.Conclusion: OPtain120 was safely consumed over a 12-week period. OPtain120 appears to be effective in lowering Systolic Blood Pressure at bedtime in healthy individuals with slightly elevated blood pressure. This study suggests that onion-pumpkin extract may aid individuals who manage their cardiovascular risk factors with diet and lifestyle.Key Words: pumpkin, onion, extract, blood pressure
Dispersion estimates for 2D Dirac equation
Authors: Kopylova E.A. 
Published: November 2019

We obtain a dispersion long-time decay in weighted norms for solutions of the 2D Dirac equation with generic potentials. For high energy component we develop the approach of Boussaid relying on the Mourre estimates and the minimal escape velocity estimates of Hunziker, Sigal and Soffer. For the low energy component we obtain the asymptotics of the resolvent near the thresholds in the nonsingular case and apply 2D version of Jensen–Kato lemma on “one-and-half partial integration”. The results can be applied to the study of asymptotic stability and scattering of solitons for nonlinear 2D Dirac equations.
Large-time behavior of small solutions of a two-dimensional semilinear elliptic equation with a dynamical boundary condition
Authors: Fila Marek , Ishige Kazuhiro , Kawakami Tatsuki 
Published: November 2019

We consider the following initial value problem for a two-dimensional semilinear elliptic equation with a dynamical boundary condition: −Δu=up, x∈R2+, t>0, ∂tu+∂νu=0, x∈∂R2+, t>0, u(x,0)=φ(x1)≥0, x=(x1,0)∈∂R2+, where u=u(x,t), ∂t:=∂/∂t, ∂ν:=−∂/∂x2, R2+:={(x1,x2): x1∈R,x2>0} and p>1. We show that small solutions behave asymptotically like suitable multiples of the Poisson kernel. This is an extension of previous results of the authors of this paper to the two-dimensional case.
On the rate of convergence of solutions in domain with random multilevel oscillating boundary
Authors: Chechkin G.A. , D'Apice C. , De Maio U. , Piatnitski A.L. 
Published: November 2019

In the paper we deal with the homogenization problem for the Poisson equation in a singularly perturbed domain with multilevel oscillating boundary. This domain consists of the body, a large number of thin periodically situated cylinders joining to the body through thin random transmission zone with rapidly oscillating boundary. Inhomogeneous Fourier boundary conditions with perturbed coefficients are set on the boundaries of the thin cylinders and on the boundary of the transmission zone. We prove the homogenization theorems. Moreover we derive estimates of deviation of the solution to initial problem from the solution to the homogenized problem in different cases. It appears that depending on small parameters in Fourier boundary conditions of initial problem one can obtain Dirichlet, Neumann or Fourier boundary conditions in the homogenized problem. We estimate the convergence of solutions in these three cases.
A novel generalized solution expansion for the Lagerstrom model
Authors: Ou Chunhua , Wong R. 
Published: November 2019

In this paper we re-visit the Lagerstrom problem y" + (n-1)/r y' + εyy' = 0, y(1) = 0, y(∞) = 1, where ε is a small positive real number and n is a positive integer (or any real number greater than 2). Using rigorous analysis, a generalized asymptotic expansion, as ε→0, is derived for the solution of this problem. A trans-series expansion of the solution for large values of r is also presented; the leading term coefficient is determined by a connection formula between the values of the solution at the two points r=1 and r=∞. An extension and a discussion of the problem for n∈[1,2) is also given.
Overdamping and energy decay for abstract wave equations with strong damping
Authors: Goldstein Gisèle Ruiz , Goldstein Jerome A. , Reyes Guillermo 
Published: November 2019

In Quart. Appl. Math. 71 (2013), 183–199, the authors find sharp exponential rates for the energy decay of nontrivial solutions to the abstract telegraph equation utt+2aut+S2u=0, where S is a strictly positive self-adjoint operator in a (complex) Hilbert space and a is a positive constant. The aim of this paper is a further extension of these results by considering equations of the form utt+2F(S)ut+S2u=0, where the damping term involves the action of the positive self-adjoint operator F(S). The main assumption on the continuous function F :(0,+∞)→(0,+∞) is that g(x)=F(x)−x changes sign only once, being positive close to zero. We obtain sharp estimates of the form E(t)≤Ce−2αt, where α>0 depends on the relative position of the bottom of the spectrum of S and the point where g vanishes, as well as on the specific behavior of F on the spectrum of S. The general result is then applied to some particular classes of functions F. We also provide a number of applications.
Fractal powers in Serrin's swirling vortex solutions
Authors: Bělík Pavel , Dokken Douglas P. , Scholz Kurt , Shvartsman Mikhail M. 
Published: November 2019

We consider a modification of the fluid flow model for a tornado-like swirling vortex developed by Serrin [Phil. Trans. Roy. Soc. London, Series A, Math & Phys. Sci. 271(1214) (1972), 325–360], where velocity decreases as the reciprocal of the distance from the vortex axis. Recent studies, based on radar data of selected severe weather events [Mon. Wea. Rev. 133(9) (2005), 2535–2551; Mon. Wea. Rev. 128(7) (2000), 2135–2164; Mon. Wea. Rev. 133(1) (2005), 97–119], indicate that the angular momentum in a tornado may not be constant with the radius, and thus suggest a different scaling of the velocity/radial distance dependence. Motivated by this suggestion, we consider Serrin's approach with the assumption that the velocity decreases as the reciprocal of the distance from the vortex axis to the power b with a general b>0. This leads to a boundary-value problem for a system of nonlinear differential equations. We analyze this problem for particular cases, both with nonzero and zero viscosity, discuss the question of existence of solutions, and use numerical techniques to describe those solutions that we cannot obtain analytically.
A nonlinear general Neumann problem involving two critical exponents

We discuss the existence of solutions to the following nonlinear problem involving two critical Sobolev exponents −div (p(x)∇u)=β|u|2*−2u+f(x,u)   in Ω, u≢0   in Ω, ∂u/∂ν=Q(x)|u|2*−2u   on ∂Ω, where β≥0, Q is continuous on ∂Ω, p∈H1(Ω) is continuous and positive in Ω¯ and f is a lower-order perturbation of |u|2*−1 with f(x,0)=0.
On a Φ-Kirchhoff multivalued problem with critical growth in an Orlicz–Sobolev space
Authors: Figueiredo Giovany M. , Santos Jefferson A. 
Published: November 2019

This paper is concerned with the multiplicity of nontrivial solutions in an Orlicz–Sobolev space for a nonlocal problem with critical growth, involving N-functions and theory of locally Lipschitz continuous functionals. More precisely, in this paper, we study a result of multiplicity to the following multivalued elliptic problem: −M(∫ΩΦ(|∇u|) dx)ΔΦu∈∂F(·,u)+αh(u)   in Ω, u∈W01LΦ(Ω), where Ω⊂RN is a bounded smooth domain, N≥3, M is a continuous function, Φ is an N-function, h is an odd increasing homeomorphism from R to R, α is positive parameter, ΔΦ is the corresponding Φ-Laplacian and ∂F(·,t) stands for Clarke generalized of a function F linked with critical growth. We use genus theory to obtain the main result.
Existence and localization of solutions for nonlocal fractional equations
Authors: Molica Bisci Giovanni , Repovš Dušan 
Published: November 2019

This work is devoted to the study of the existence of at least one weak solution to nonlocal equations involving a general integro-differential operator of fractional type. As a special case, we derive an existence theorem for the fractional Laplacian, finding a nontrivial weak solution of the equation (−Δ)su=h(x)f(u) in Ω, u=0 in Rn\Ω, where h∈L∞+(Ω)\{0} and f :R→R is a suitable continuous function. These problems have a variational structure and we find a nontrivial weak solution for them by exploiting a recent local minimum result for smooth functionals defined on a reflexive Banach space. To make the nonlinear methods work, some careful analysis of the fractional spaces involved is necessary.
Resonance widths in a case of multidimensional phase space tunneling
Authors: Grigis Alain , Martinez André 
Published: November 2019

Motivated by the study of resonances for molecular systems in the Born–Oppenheimer approximation, we consider a semiclassical 2×2 matrix Schrödinger operator of the form P=−h2ΔI2+diag (xn−μ,τV2(x))+hR(x,hDx), where μ and τ are two small positive constants, V2 is real-analytic and admits a nondegenerate minimum at 0, and R=(rj,k(x,hDx))1≤j,k≤2 is a symmetric off-diagonal 2×2 matrix of first-order differential operators with analytic coefficients. Then, denoting by e1 the first eigenvalue of −Δ+〈τV2″(0)x,x〉/2, and under some ellipticity condition on r1,2=r2,1*, we show that, for any μ sufficiently small, and for 0<τ≤τ(μ) with some τ(μ)>0, the unique resonance ρ of P such that ρ=τV2(0)+(e1+r2,2(0,0))h+𝒪(h2) (as h→0+) satisfies Im ρ=−h3/2f(h,ln 1/h)e−2S/h, where f(h,ln 1/h)~Σ0≤m≤ℓfℓ,mhℓ(ln 1/h)m is a symbol with f0,0>0, and S is the imaginary part of the complex action along some convenient closed path containing (0,0) and consisting of a union of complex nul-bicharacteristics of p1:=ξ2−xn−μ and p2:=ξ2+τV2(x) (broken instanton). This broken instanton is described in terms of the outgoing and incoming complex Lagrangian manifolds associated with p2 at the point (0,0), and their intersections with the characteristic set p1−1(0) of p1.
Nonnegative solutions for a class of singular parabolic problems involving p-Laplacian
Authors: de Bonis Ida , Giachetti Daniela 
Published: November 2019

We deal with the existence of nonnegative solutions to parabolic problems which are singular in the u variable whose model is ut−Δpu=f(x,t)(1/uθ+1) in Ω×(0,T), u(x,t)=0 on ∂Ω×(0,T), u(x,0)=u0(x) in Ω. Here Ω is a bounded open subset of RN, N≥2, 0<T<+∞, θ>0, Δpu=div (|∇u|p−2∇u) with p>1. As far as the data are concerned, we assume f(x,t)∈Lr(0,T;Lm(Ω)), with 1/r+N/pm<1, f(x,t)≥0 a.e. in Ω×(0,T) and u0(x)≥0 a.e. in Ω. We consider also the case where the right-hand side depends on the gradient of the solution. In this last case the model of the right-hand side is F(x,t,u,∇u)=(f(x,t)+D|∇u|q)/uθ, with θ>0, D>0, 1<q<p and f(x,t) as before.
Boundedness of global solutions of a p-Laplacian evolution equation with a nonlinear gradient term
Authors: Attouchi Amal 
Published: November 2019

We investigate the boundedness and large time behavior of solutions of the Cauchy–Dirichlet problem for the one-dimensional degenerate parabolic equation with gradient nonlinearity: ut=(|ux|p−2ux)x+|ux|q in (0,∞)×(0,1),q>p>2. We prove that: either ux blows up in finite time, or u is global and converges in W1,∞(0,1) to the unique steady state. This in particular eliminates the possibility of global solutions with unbounded gradient. For that purpose a Lyapunov functional is constructed by the approach of Zelenyak.
Basis properties in a problem of a nonhomogeneous string with damping at the end
Authors: Gomilko Alexander , Rzepnicki Łukasz 
Published: November 2019

This paper is concerned with the equation of a nonhomogeneous string of length one with one end fixed and the other one damped with a parameter h∈C. This problem can be rewritten as an abstract Cauchy problem for a densely defined closed operator iAh acting on an appropriate energy Hilbert space H. Under assumptions that the density function of the string ρ∈W21[0,1] is strictly positive and has ρ(1)≠h2 (if h∈R), we prove that the set of root vectors of Ah form a basis with parentheses in H. We show that with the additional condition ∫01ω12(ρ′,τ)/τ2 dτ<∞, where ω1 is the integral modulus of continuity, the root vectors of the operator Ah form a Riesz basis in H.

Published: November 2019

The one-dimensional Dirac operator [Formula: see text] considered on $[0,\uppi ]$ with periodic or antiperiodic boundary conditions, has discrete spectra. For large enough |n|, n∈Z, there are two (counted with multiplicity) eigenvalues λn−, λn+ (periodic if n is even, or antiperiodic if n is odd) such that |λn±−n|<1/2. We study the asymptotics of spectral gaps γn=λn+−λn− in the case P(x)=ae−2ix+Ae2ix,  Q(x)=be−2ix+Be2ix, where a, A, b, B are any complex numbers. We show, for large enough m, that γ±2m=0 and [Formula: see text]
