description: Darboux transformations are employed in construction and analysis of Dirac Hamiltonians with pseudoscalar potentials. By this method, we build a four parameter class of reflectionless systems. Their potentials correspond to composition of complex kinks, also known as twisted kinks, that play an important role in the $1+1$ Gross-Neveu and Nambu-Jona-Lasinio field theories. The twisted kinks turn out to be multi-solitonic solutions of the integrable AKNS hierarchy. Consequently, all the spectral properties of the Dirac reflectionless systems are reflected in a non-trivial conserved quantity, which can be expressed in a simple way in terms of Darboux transformations. We show that the four parameter pseudoscalar systems reduce to well-known models for specific choices of the parameters. An associated class of transparent non-relativistic models described by matrix Schrödinger Hamiltonian is studied and the rich algebraic structure of their integrals of motion is discussed.

description: We construct the D4/D8 brane configuration in the Witten-Sakai-Sugimoto model by introducing a pair of heavy flavour brane with a heavy-light open string. The multiplets created by the heavy-light string acquire mass due to the finite separation of the heavy and light flavour branes thus they could be identified as the heavy-light meson fields in this model. On the other hand the glueball field is identified as the gravitational fluctuations carried by the close string in the bulk, so this model is able to describe the interaction of glueball and heavy-light meson through the open-close string interaction in gauge-gravity duality. We explicitly derive the effective action for the various glueballs and heavy-light mesons then numerically evaluate the associated coupling constants. Afterwards the decay widths of various glueballs to the lowest heavy-light meson, which is identified as $D^{0}$ meson, are calculated by using our effective action. This work extends the previous investigations of glueball in holographic QCD and it is also a further prediction of glueball-meson interaction.

subject: FOS: Physical sciences

description: The uncertainty principle being a cornerstone of quantum mechanics, it is surprising that in nearly 90 years there have been no direct tests of measurement uncertainty relations. This lacuna was due to the absence of two essential ingredients: appropriate measures of measurement error (and disturbance), and precise formulations of such relations that are {\em universally valid}and {\em directly testable}. We formulate two distinct forms of direct tests, based on different measures of error. We present a prototype protocol for a direct test of measurement uncertainty relations in terms of {\em value deviation errors} (hitherto considered nonfeasible), highlighting the lack of universality of these relations. This shows that the formulation of universal, directly testable measurement uncertainty relations for {\em state-dependent} error measures remains an important open problem. Recent experiments that were claimed to constitute invalidations of Heisenberg's error-disturbance relation are shown to conform with the spirit of Heisenberg's principle if interpreted as direct tests of measurement uncertainty relations for error measures that quantify {\em distances between observables}.

description: We show that the quantum automorphism group of the Clebsch graph is $SO_5^{-1}$. This answers a question by Banica, Bichon and Collins from 2007. More general for odd $n$, the quantum automorphism group of the folded $n$-cube graph is $SO_n^{-1}$. Furthermore, we show that if the automorphism group of a graph contains a pair of disjoint automorphisms this graph has quantum symmetry.

description: We apply principal component analysis to the study of event-by-event fluctuations in relativistic heavy-ion collisions. This method brings out all the information contained in two-particle correlations in a physically transparent way. We present a guide to the method, and apply it to multiplicity fluctuations and anisotropic flow, using ALICE data and simulated events. In particular, we study elliptic and triangular flow fluctuations as a function of transverse momentum and rapidity. This method reveals previously unknown subleading modes in both rapidity and transverse momentum for the momentum distribution as well as elliptic and triangular flows.

description: The interaction between phonons and high-energy excitations of electronic origin in cuprates and their role in the superconducting mechanisms is still controversial. Here we use coherent vibrational time-domain spectroscopy together with density functional and dynamical mean-field theory calculations to establish a direct link between the c-axis phonon modes and the in-plane electronic charge excitations in optimally doped YBCO. The non-equilibrium Raman tensor is measured by means of the broadband 'coherent-phonon' response in pump-probe experiments and is qualitatively described by our model using DFT in frozen phonon approximation plus single band DMFT to account for the electronic correlations. The major outcome of our experimental and theoretical study is to establish the link between out-of-plane copper ions displacements and the in-plane electronic correlations, and to estimate at few unit cells the correlation length of the associated phonon mode. The approach introduced here could help revealing the complex interplay between fluctuations of different nature and spatial correlation in several strongly-correlated materials.

Spinor Structure and Internal Symmetries

description: Spinor structure and internal symmetries are considered within one theoretical framework based on the generalized spin and abstract Hilbert space. Complex momentum is understood as a generating kernel of the underlying spinor structure. It is shown that tensor products of biquaternion algebras are associated with the each irreducible representation of the Lorentz group. Space-time discrete symmetries $P$, $T$ and their combination $PT$ are generated by the fundamental automorphisms of this algebraic background (Clifford algebras). Charge conjugation $C$ is presented by a pseudoautomorphism of the complex Clifford algebra. This description of the operation $C$ allows one to distinguish charged and neutral particles including particle-antiparticle interchange and truly neutral particles. Spin and charge multiplets, based on the interlocking representations of the Lorentz group, are introduced. A central point of the work is a correspondence between Wigner definition of elementary particle as an irreducible representation of the Poincaré group and $SU(3)$-description (quark scheme) of the particle as a vector of the supermultiplet (irreducible representation of $SU(3)$). This correspondence is realized on the ground of a spin-charge Hilbert space. Basic hadron supermultiplets of $SU(3)$-theory (baryon octet and two meson octets) are studied in this framework. It is shown that quark phenomenologies are naturally incorporated into presented scheme. The relationship between mass and spin is established. The introduced spin-mass formula and its combination with Gell-Mann--Okubo mass formula allows one to take a new look at the problem of mass spectrum of elementary particles.

description: Diese Arbeit setzt sich mit der Analyse der Tanztheateraufführungen Radio Freedom und Und die Erde ist doch eine Scheibe auseinander, welche digitale Medien, wie Videos oder dreidimensionale Projektionen beinhalten. Nachdem kurz auf die Geschichte der Medieneinflüsse im Theaterbereich eingegangen wird, sollen in dieser Arbeit verwendete Begriffe, wie Intermedialität oder digitale Medien definiert werden. Aufgrund der technologischen Entwicklungen und des alltäglichen Gebrauchs digitaler Medien steigt das Bedürfnis nach einer Annäherung von Theater/Performance und digitalen Welten. Den Hauptgegenstand dieser Arbeit bildet die Frage, welche Auswirkungen der Einsatz digitaler Medien im Theater auf dramaturgische Konzepte hat. Konkrete Fragestellungen lauten etwa: Welche unterstützenden dramaturgischen Effekte hat der Einsatz digitaler Medien auf das Tanztheater? Wie kann der Einsatz digitaler Medien der Aufführung eine zusätzliche ästhetische Dimension verleihen? Welche Auswirkungen haben die digitalen Medien auf räumliche Aspekte? Geraten die menschlichen Figuren aufgrund eines großzügigen Einsatzes digitaler Medien auf der Bühne in den Hintergrund? Aufgrund aktueller Gegebenheiten soll ein weiteres Kapitel der Corona-Krise gewidmet werden, da das Rezipieren von theatralen Aufführungsformen während einiger Lockdowns nur mittels digitaler Medien, insbesondere Internet, ermöglicht wurde. Ziel der wissenschaftlichen Arbeit ist es, sowohl die unterstützenden Einflüsse als auch mögliche Gefahren und aufkommende Ängste hinsichtlich der Nutzung digitaler Medien im Theater herauszuarbeiten und damit einhergehende Aspekte, wie die sich verändernde Zuschauerrolle oder den pädagogischen Wert für Kinder und Jugendliche, zu thematisieren.

description: Deep neural networks typically outperform more traditional machine learning models in their ability to classify complex data, and yet is not clear how the individual hidden layers of a deep network contribute to the overall classification performance. We thus introduce a Generalized Discrimination Value (GDV) that measures, in a non-invasive manner, how well different data classes separate in each given network layer. The GDV can be used for the automatic tuning of hyper-parameters, such as the width profile and the total depth of a network. Moreover, the layer-dependent GDV(L) provides new insights into the data transformations that self-organize during training: In the case of multi-layer perceptrons trained with error backpropagation, we find that classification of highly complex data sets requires a temporal {\em reduction} of class separability, marked by a characteristic 'energy barrier' in the initial part of the GDV(L) curve. Even more surprisingly, for a given data set, the GDV(L) is running through a fixed 'master curve', independently from the total number of network layers. Furthermore, applying the GDV to Deep Belief Networks reveals that also unsupervised training with the Contrastive Divergence method can systematically increase class separability over tens of layers, even though the system does not 'know' the desired class labels. These results indicate that the GDV may become a useful tool to open the black box of deep learning.

description: We study a strongly attractive system of a few spin-1/2 fermions confined in a one-dimensional harmonic trap, interacting via two-body contact potential. Performing exact diagonalization of the Hamiltonian we analyze the ground state and the thermal state of the system in terms of one-- and two--particle reduced density matrices. We show how for strong attraction the correlated pairs emerge in the system. We find that the fraction of correlated pairs depends on temperature and we show that this dependence has universal properties analogous to the gap function known from the theory of superconductivity. In contrast to the standard approach based on the variational ansatz and/or perturbation theory, our predictions are exact and are valid also in a strong attraction limit. Our findings contribute to the understanding of strongly correlated few-body systems and can be verified in current experiments on ultra-cold atoms.

We then consider ensembles of grammars, in particular the Random Language Model of E. DeGiuli, Phys. Rev. Lett., 122, 128301, 2019. This model is solved in the replica-symmetric ansatz, which is valid in the high-temperature, disordered phase. It is shown that in the phase in which languages carry information, the replica symmetry must be broken.

description: Hidden sector dark matter (DM) models with local dark gauge symmetry make a natural playground for the $γ$-ray excess from the galactic center (GC). In this paper, we first discuss in detail the GC $γ$-ray excess in scalar dark matter model with local $Z_{3}$ symmetry which was recently proposed by the present authors. Within this model, scalar DM with mass $30-70$GeV is allowed due to newly-opened (semi-)annihilation channels of DM pair into dark Higgs $ϕ$ and/or dark photon $Z^{'}$ pair, and can fit the $γ$-ray spectrum from the GC. Then we argue that the GC gamma ray excess can be easily accommodated in hidden sector dark matter models where DM is stabilized by local gauge symmetries, due to the presence of dark Higgs (and also dark photon for Abelian dark gauge symmetry). As by-products, the Higgs portal interaction between the dark Higgs and the SM Higgs boson can improve the EW vacuum stability up to Planck scale, and enable the Higgs inflation scenario to have potentially large tensor-to-scalar ratio, $r\sim O(0.01 - 0.1)$.

description: We report the observation of the baryonic decay $\bar{B}^0 \to Λ^+_c \bar{p} K^- K^+$ using a data sample of $471 \times 10^6$ $B\bar{B}$ pairs produced in $e^+e^-$ annihilations at $\sqrt{s}=10.58 \mathrm{\,GeV}$. This data sample was recorded with the $BABAR$ detector at the PEP-II storage ring at SLAC. We find ${\cal B}\left(\bar{B}^0 \to Λ^+_c \bar{p} K^- K^+ \right) = \left(2.5 \pm 0.4_{(\text{stat})} \pm 0.2_{(\text{syst})}\pm 0.6_{{\cal B}\left(Λ^+_c\right)} \right) \times 10^{-5}$, where the uncertainties are statistical, systematic, and due to the uncertainty of the $Λ^+_c \to p K^- π^+$ branching fraction, respectively. The result has a significance corresponding to 5.0 standard deviations, including all uncertainties. For the resonant decay $\bar{B}^0 \to Λ^+_c \bar{p} ϕ$, we determine the upper limit ${\cal B}\left(\bar{B}^0 \to Λ^+_c \bar{p} ϕ\right) <1.2 \times 10^{-5}$ at $90\%$ confidence level.

In this configuration, more complex quantum coherent and interference phenomena occur. In partic- ular, we find that the probe transmission spectra depend on the total phase of the applied fields. Our study also provides an efficient way to control propagation of amplification.

Efficient calibration for high-dimensional computer model output using basis methods

Publisher: name: arXiv
Year: 2019
Subjects: subject: Methodology (stat.ME)

description: Calibration of expensive computer models with high-dimensional output fields can be approached via history matching. If the entire output field is matched, with patterns or correlations between locations or time points represented, calculating the distance metric between observational data and model output for a single input setting requires a time intensive inversion of a high-dimensional matrix. By using a low-dimensional basis representation rather than emulating each output individually, we define a metric in the reduced space that allows the implausibility for the field to be calculated efficiently, with only small matrix inversions required, using projection that is consistent with the variance specifications in the implausibility. We show that projection using the $L_2$ norm can result in different conclusions, with the ordering of points not maintained on the basis, with implications for both history matching and probabilistic methods. We demonstrate the scalability of our method through history matching of the Canadian atmosphere model, CanAM4, comparing basis methods to emulation of each output individually, showing that the basis approach can be more accurate, whilst also being more efficient.

description: Terahertz emission between exciton-polariton branches in semiconductor microcavities is expected to be strongly stimulated in the polariton laser regime, due to the high density of particles in the lower state (final state stimulation effect). However, non-radiative scattering processes depopulate the upper state and greatly hinder the efficiency of such terahertz sources. In this work, we suggest a new scheme using multiple microcavities and exploiting the transition between two interband polariton branches located below the exciton level. We compare the non-radiative processes loss rates in single and double cavity devices and we show that a dramatic reduction can be achieved in the latter, enhancing the efficiency of the terahertz emission.

description: Das Ziel dieser Masterarbeit besteht darin herauszufinden, ob das Mentoring als Teil der Induktionsphase in Österreich die Professionalisierung von Lehrpersonen im Berufseinstieg fördern kann. Basierend auf dem berufsbiographischen Bestimmungsansatz von pädagogischer Professionalität wird Professionalisierung in diesem Kontext als Prozess der Bewältigung von beruflichen Herausforderungen verstanden, der in weiterer Folge die berufliche Weiterentwicklung von Lehrkräften befördert. Mithilfe einer Interview-Studie, in der sieben Lehrkräfte, die sich zur Zeit der Durchführung der Interviews in der Induktionsphase befanden oder diese bereits abgeschlossen haben, wurden zuerst die Herausforderungen und Entwicklungsaufgaben, die deren Berufseinstiegsphase charakterisieren, erläutert. In weiterer Folge wurde anhand der Erfahrungsberichte dargelegt, inwiefern das Mentoring ihnen eine Unterstützung bei den Herausforderungen bot und welche weiteren Unterstützungsangebote ihnen bei den Entwicklungsaufgaben halfen. Dabei konnte herausgefunden werden, dass das Mentoring in der Induktionsphase das Potential besitzt, die Professionalisierung von Lehrpersonen im Berufseinstieg zu fördern, indem es vier der sieben BerufseinsteigerInnen bei den zahlreichen beruflichen Aufgaben jedenfalls unterstützen konnte. Allerdings konnte festgestellt werden, dass die Art und Weise der Umsetzung sowie die Wirksamkeit des Mentorings auch vom Kontext der InterviewpartnerInnen abhängt, wie beispielsweise von den Rahmenbedingungen an den unterschiedlichen Schulstandorten sowie von den individuellen Dispositionen der am Mentoring beteiligten Personen, wie zum Beispiel vom Vorwissen der MentorInnen durch eine absolvierte Mentoringausbildung.

description: A new family of non-Hermitian PT-symmetric quantum models is proposed in which the Hamiltonians $H=T+V$ are finite-dimensional and in which the dynamical-input potential $V$ is multi-parametric and non-local. The choice is supported by the exact solvability of Schrödinger equation and by the well known fact that in PT-symmetric models a non-locality is already present due to the generic kinematical non-diagonality of the Hermitizing metrics $Θ$. For a subfamily of our $H$s, also {\em all\,} of the eligible metrics $Θ$ appear obtainable in closed form.

Die ROW Lampe zeichnet sich durch einen leuchtend orange-roten Überzug über einer weißen Engobe aus und erfreute sich vom 1. bis ins 3. Jahrhundert großer Beliebtheit. Anhand einer ersten mikroskopischen Analyse von 50 Proben aus Ephesos konnten zwei Haupttonarten unterschieden werden. Der Ton ist rötlich-braun und fein geschlämmt und zeigt unterschiedlichen Einschlüsse. Ein zweiter Teil widmet sich dem Aussehen und der Verzierungen der ROW Lampe, wobei zunächst eine Typo-Chronologie erstellt wurde. Dabei zeigen sich drei Haupttypen, welche aufgrund der Schnauzenform zu unterscheiden sind. Die Charakteristik des ROW Typs I besteht in einer Volutenschnauze, wohingegen ROW Typ II eine abgesetzte und ROW Typ III eine herzförmige Schnauze aufweist. Die ROW Lampen weisen zudem auch einen großen Motivreichtum auf, sowohl auf der Schulter, den Reflektoren und als Diskusdekoration.

We observe that the point scatterer acts as a barrier confining the low-level modes to one side of the plate while assuming the Dirichlet boundary condition at a point does not induce this type of localization. This low-energy phenomenon extends to higher modes as we increase the eccentricity of the plate.

description: We present the results of a photometric study of 85 objects from the updated sample of galaxies residing in the nearby Lynx--Cancer void. We perform our photometry on u, g, r, and i-band images of the Sloan Digital Sky Survey. We determine model-independent galaxy parameters such as the integrated magnitudes and colors, effective radii and the corresponding surface brightness values, optical radii and Holmberg radii. We analyze the radial surface brightness profiles to determine the central brightness values and scale lengths of the model discs. We analyze the colors of the outer parts of the galaxies and compare them with model evolutionary tracks computed using the PEGASE2 software package. This allowed us to estimate the time T_SF elapsed since the onset of star formation, which turned out to be on the order of the cosmological time T_0 for the overwhelming majority of the galaxies studied. However, for 13 galaxies of the sample the time T_SF does not exceed T_0/2 ~ 7 Gyr, and for 7 of them T_SF < 3.5 Gyr. The latter are mostly unevolved objects dominated by low-luminosity galaxies with M_B > -13.2. We use the integrated magnitudes and colors to estimate the stellar masses of the galaxies. We estimate the parameter M(HI)/L_B and the gas mass fractions for void galaxies with known HI-line fluxes. A small subgroup (about 10%) of the gas-richest void galaxies with M(HI)/L_B > 2.5 has gas mass fractions that reach 94-99%. The outer regions of many of these galaxies show atypically blue colors. To test various statistical differences between void galaxies and galaxies from the samples selected using more general criteria, we compare some of the parameters of void galaxies with similar data for the sample of 195 galaxies from the Equatorial Survey (ES) based on a part of the HIPASS blind HI survey. abridged

description: The study was carried out to determine the different productive and reproductive parameters and their correlation with time periods (P1, P2, P3, P4, P5 and P6) and seasons (S1, S2, S3 and S4) in Crossbred (Jersey X Sahiwal) cows at Dairy Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh (India). Productive and reproductive data such as body weight, lactation yield, lactation period age at first calving, calving interval and gestation period of crossbred (Jersey X Sahiwal) cows from 2010 to 2015 was collected and used for analysis with the help of SPSS (Statistical Package for social science). The overall mean of weight, age at first calving, first lactation milk yield, first lactation period, calving interval, gestation period was 421.85 ± 1.43 kg, 1662.55± 0.208 days, 2238.42 ± 13.69 liters, 289.23 ± 8.96 days, 399.61 ± 5.96 days, 283.27± 0.42 days, respectively. Cows belonging to 4th batch recorded significantly (P<0.05) higher lactation milk yield of 2475.93 ± 19.65 liters in the present study. Cows born during rainy and winter seasons matured at significantly earlier age (750.18 ± 0.79 and 760.18 ± 0.18 days, respectively). Lowest age at first calving (1092.46 ± 7.47 days) was observed in cows born in winter followed by those born in rainy (1134.88 ± 6.47 days) and summer (1173.95 ± 5.89 days) seasons. It can be concluded that crossbred (Jersey X Sahiwal) cows have shown a good productive as well as reproductive performance during the present study and should be managed in such a way so that the calving interval and dry period can be reduced up to the maximum extent to enhance the lactation period and milk yield. Based on the current findings, parturition should take place during the winter season rather than summer or rainy seasons.

description: We review the empirical comparison of SAOMs and TERGMs by Leifeld and Cranmer (2019) in Network Science. We note that their model specification uses nodal covariates calculated from observed degrees instead of using structural effects, thus turning endogeneity into circularity. In consequence, their out-of-sample predictions using TERGMs are based on out-of-sample information and thereby predict the future using observations from the future. We conclude that their analysis rest on erroneous model specifications that render the article's conclusions meaningless. Consequently, researchers should disregard recommendations from the criticized paper when making informed modelling choices.

description: We discuss a sufficiently large 4-dimensional Schwarzschild black hole which is in equilibrium with a heat bath. In other words, we consider a black hole which has grown up from a small one in the heat bath adiabatically. We express the metric of the interior of the black hole in terms of two functions: One is the intensity of the Hawking radiation, and the other is the ratio between the radiation energy and the pressure in the radial direction. Especially in the case of conformal matters we check that it is a self-consistent solution of the semi-classical Einstein equation, $G_{μν}=8πG \langle T_{μν}\rangle$. It is shown that the strength of the Hawking radiation is proportional to the c-coefficient, that is, the coefficient of the square of the Weyl tensor in the 4-dimensional Weyl anomaly.

description: The decomposition of electronic and nuclear motion presented in~[A. Abedi, N. T. Maitra, and E. K. U. Gross, Phys. Rev. Lett. 105, 123002 (2010)] yields a time-dependent potential that drives the nuclear motion and fully accounts for the coupling to the electronic subsystem. Here we show that propagation of an ensemble of independent classical nuclear trajectories on this exact potential yields dynamics that are essentially indistinguishable from the exact quantum dynamics for a model non-adiabatic charge transfer problem. We point out the importance of step and bump features in the exact potential that are critical in obtaining the correct splitting of the quasiclassical nuclear wave packet in space after it passes through an avoided crossing between two Born-Oppenheimer surfaces, and analyze their structure. Lastly, an analysis of the exact potentials in the context of trajectory surface hopping procedure is presented, including preliminary investigations of velocity-adjustment, and the force-induced decoherence effect.

Critique of Quantum Optical Experimental Refutations of Bohr's Principle of Complementarity, of the Wootters-Zurek Principle of Complementarity, and of the Particle-Wave Duality Relation

description: I argue that quantum optical experiments that purport to refute Bohr's principle of complementarity (BPC) fail in their aim. Some of these experiments try to refute complementarity by refuting the so called particle-wave duality relations, which evolved from the Wootters-Zureck reformulation of BPC (WZPC). I therefore consider it important for my forgoing arguments to first recall the essential tenets of BPC, and to clearly separate BPC from WZPC, which I will argue is a direct contradiction of BPC. This leads to a need to consider the meaning of particle-wave duality relations and to question their fundamental status. I further argue (albeit, in opposition to BPC) that particle and wave complementary concepts are on a different footing than other pairs of complementary concepts.

description: Модальные испытания летательных аппаратов (ЛА) проводятся с целью определения собственных частот, форм, обобщенных масс и характеристик демпфирования собственных тонов колебаний. Эти модальные параметры используются в оценках эксплуатационной нагруженности, обеспечении прочности, управляемости и аэроупругой устойчивости ЛА. Предлагаемый способ испытаний относится к классическому экспериментальному модальному анализу динамических систем. Для его реализации выделяются собственные тона колебаний конструкции в заданном частотном диапазоне методом фазового резонанса путем использования многоканальной системы возбуждения и измерения колебаний. Определяются собственные частоты тонов по фазовым резонансам. По соотношениям между вынужденными монофазными и собственными колебаниями выявляются диссипативные свойства динамической системы. Так, если монофазные колебания при монофазном возбуждении совпадают с собственными на частотах, отличающихся от собственных частот, то колебания конструкции по каждому собственному тону описываются уравнением движения линейного осциллятора. Параметрами осциллятора являются обобщенная масса, обобщенное демпфирование и обобщенная жесткость соответствующего тона. Определение параметров осциллятора производится по амплитудно-частотной характеристике конструкции в окрестности частоты фазового резонанса из условия минимума различия обобщенных сил, реализующих одинаковые амплитуды колебаний конструкции и осциллятора. Если же монофазные колебания при монофазном возбуждении не существуют или не совпадают с собственными колебаниями, то для определения модальных параметров используется немонофазное возбуждение. Достоинствами такого способа идентификации модальных характеристик конструкций является обоснованность принимаемой модели демпфирования, низкая чувствительность к погрешностям измерений колебаний в процессе испытаний и к взаимному влиянию тонов с близкими собственными частотами, а также возможность оценки достоверности определения обобщенных масс и жесткостей через частоты фазовых резонансов. Достоверность определяемых предложенным способом обобщенных характеристик собственных тонов колебаний подтверждена результатами модальных испытаний динамически подобной модели самолета Ту-334 и натурных изделий Су-30, Як-152 и агрегата космического аппарата.
