Food sovereignty and education: A Japanese type of harmonization

Every civilization has specific social-cultural rituals for eating, and contemporary Japan is a particularly interesting case. The architects of the Japanese food policy use a special respect for food in two ways: first, as a tool of soft power to spread Japanese influence worldwide; second, as an effective way to ensure food security. It is the second component that interests the authors. The article identifies key issues of Japan’s food policy. Based on the institutional analysis and the food regime theory, the authors identify the structural nature of food import dependency of the Land of the Rising Sun. The combination of the comparative approach and retrospective analysis allowed to discover a number of elements that are closely connected with the idea of food sovereignty, especially the concept of shokuiku (food education). Based on the historical-genetic method, the authors suggest a cognitive route of the terminological unit “from the component of folklore to the legislative act” and identify structural-functional features of the Basic Law ( Shokuiku Kihon-ho ). The analysis of three Basic Plans for promotion of Shokuiku proved the institutional reorientation of Japan to collectivism, healthy lifestyle and dietetics of younger generations. Despite the fact that effectiveness of re-profiling was verified by empirical data, the article provides a critical analysis of shokuiku as well. The state monopoly on food knowledge and risk discourse legitimize ideologies, generate alarmist feelings and lead to food nationalism.

Characterising the harmonic vocal repertoire of the Indian wolf (Canis lupus pallipes).

Vocal communication in social animals plays a crucial role in mate choice, maintaining social structure, and foraging strategy. The Indian grey wolf, among the least studied subspecies, is a social carnivore that lives in groups called packs and has many types of vocal communication. In this study, we characterise harmonic vocalisation types of the Indian wolf using howl survey responses and opportunistic recordings from captive and nine packs (each pack contains 2–9 individuals) of free-ranging Indian wolves. Using principal component analysis, hierarchical clustering, and discriminant function analysis, we found four distinct vocalisations using 270 recorded vocalisations (Average Silhouette width Si = 0.598) which include howls and howl-barks (N = 238), whimper (N = 2), social squeak (N = 28), and whine (N = 2). Although having a smaller body size compared to other wolf subspecies, Indian wolf howls have an average mean fundamental frequency of 422 Hz (±126), which is similar to other wolf subspecies. The whimper showed the highest frequency modulation (37.296±4.601) and the highest mean fundamental frequency (1708±524 Hz) compared to other call types. Less information is available on the third vocalisation type, i.e. ‘Social squeak’ or ‘talking’ (Mean fundamental frequency = 461±83 Hz), which is highly variable (coefficient of frequency variation = 18.778±3.587). Lastly, we identified the whine, which had a mean fundamental frequency of 906Hz (±242) and is similar to the Italian wolf (979±109 Hz). Our study’s characterisation of the Indian wolf’s harmonic vocal repertoire provides a first step in understanding the function and contextual use of vocalisations in this social mammal.

Compensation for the Influence of Fluctuations in the Distance to the Object During Noncontact Probing in Spectral Domain Optical Coherence Tomography

We propose and experimentally test a numerical method for correction of the influence of fluctuations in the distance to objects during noncontact probing in optical coherence tomography. The method is based on the analysis of phase shifts of the neighboring scans, which are due to microscale displacements, and further compensation for these displacements by using phasefrequency correction in the spectral domain. Unlike the known correlation methods, the proposed method does not distort the represented shape of the object surface. Its operability is demonstrated in model experiments in the cases of harmonic and random types of the motion of the scattering object, as well as in vivo imaging of the structures of the human middle ear.

Enforcement of Harmonization Relying on the Country of Origin Principle

The Country of Origin (COO) Principle is frequently used as the template for secondary legislation aiming at realizing the internal market. The main feature of the harmonization using this model is that the home Member State should enforce the minimum requirement agreed on for issuing the relevant authorization, licence, etc. The other Member States in which the authorization, etc., is used (the host Member States) should recognize the harmonization and should neither enforce their own conditions for issuing an authorization, etc., nor try to make a parallel enforcement of the harmonized minimum requirement. Thus, the proper compliance with this type of harmonization faces two challenges: how to ensure that the host Member State enforces the minimum requirements agreed upon and continues to ensure that these are complied with, and how to ensure that the host Member States do not take it upon themselves to enforce the same requirements. If these two challenges are not overcome, the harmonization is not likely to work as intended, and consequently both the EU legislator and the Court of Justice of the European Union have taken different steps to overcome these challenges. By focusing on a selection of different areas using the COO Principle (insurance, driving licence, road haulage transport, audiovisual media services and credit institutions) these challenges and the remedies put in place to overcome them are analysed. This includes an analysis of recent reforms undertaken in these areas as well as an analysis of relevant case law. It is shown that different approaches have been used successfully to ensure better compliance, but there also seems to be approaches that are either less functional or a ‘no go’.

MUSCLE SPASTICITY AND ITS INTERACTION WITH MYOFASCIAL SYSTEM OF CHILDREN WITH CENTRAL PARESIS

Traditionally, the problem of muscle spasticity was considered by experts as a kind of local problem associated with the inhibition or traumatisation of the central motor neuron in a certain part of its path. According to this approach, only the first stage of the causal relationship of the two systems was reflected: the nervous and the muscular systems. In the following, intrasystem relations of the muscle and muscle complex appeared according to the type of harmonization or destructivization of the activity of this system. To resolve this problematic situation, the article examines the original theory of Thomas V. Myers about “anatomical trains” or “myofascial meridians” as an integral musculoskeletal system of the human body, which forms the basis of its anatomy and motor activity. Key ideas of tensegrity as a structure of balanced compression-tension of the musculoskeletal system are identified, and it is necessary to rush to the targets, carrying out the correction of motor disorders of the tender age children with paresis of central type by means of physical education. For deeper understanding of the activities of these mechanisms of children myofascial status harmonization, the main myofascial lines were briefly characterized: surface back line, surface frontal line, lateral line, spiral line, arm lines. On this basis, working hypothesis was formulated as for using the holistic myofascial system capabilities of the child’s body to correct both the tonic state of individual spastic muscles and to improve the general children motor status. To check the formulated hypothesis, the directions of the implementation of correctively directed physical education of tender age children with central paresis of different localization levels were indicated. An attempt was made to use the basic knowledge of the myofascial meridians functioning to increase the efficiency of diagnosing the state of musculoskeletal formations of children with spastic paresis, developing strategies and tactics for correcting their tonic state, methods and techniques for adjusting the balance of compression and tension of these structures to improve children motor activity and to improve the efficiency of their basic motor regimes mastering. There was made a fundamental conclusion that the correctional work by means of physical education should be preceded by preparatory work aimed at normalization of the whole myofascial system of a child with a spastic type of movement disorders, which can be carried out using purely medical techniques and the techniques based on the means of children physical education. Prospects of the scientific and practical development of the problem indicated in this article are highlighted separately.

Voltage harmonic injection angle optimisation for grid current harmonics using a PV converter

In this work, the impact of voltage harmonic injection angle on grid current harmonics using a power converter supplied by photovoltaic (PV) array is studied. Converter and PV non-linear operation cause harmonic distortion, which is superimposed to the existing harmonic content of the grid. First, a general mathematical expression connecting voltage harmonic injection angle and current distortion at the same frequency is theoretically proven. This general expression is verified by experimental results for various converter output levels and grid properties, and voltage harmonic injections at various orders and amplitudes. Since the expression is a convex function, there is a unique injection angle that minimises overall current harmonic at the same frequency. The second contribution of this research is that with a minimum of three injections at random angles the parameters of the general expression can be calculated, thus the optimum injection angle can be determined. In comparison to other works, the knowledge of converter harmonic properties, grid harmonic content or grid connection type (inductive, ohmic, mixed) is not needed.

Identity involving symmetric sums of regularized multiple zeta-star values

An identity involving symmetric sums of regularized multiple zeta-star values of harmonic type was proved by Hoffman. In this paper, we prove an identity of shuffle type. We use Bell polynomials appearing in the study of set partitions to prove the identity.

Heat exchanger system boundary regulation

AbstractThe boundary feedback regulator design for heat exchangers with delayed feedback is developed. Counter‐flow/parallel‐flow heat exchanger systems described by a pair of coupled transport hyperbolic partial differential equations (PDEs) with delayed boundary feedback loop modeled by the boundary time lag are considered. The coupled transport hyperbolic PDEs and boundary delay by application of boundary transformation are transformed in the corresponding linear infinite‐dimensional system utilized in the regulator design. The regulator design initially addresses a full state feedback controller realization augmented by the observer design to achieve simultaneously output exponential stabilization as well as tracking and disturbance rejection of polynomial and/or harmonic type of reference signals. The simulations studies demonstrate the proposed design for counter‐flow and parallel‐flow heat exchangers, two common configurations present in industrial practice.

The Forelli-Rudin type theorem and a class of integral operator related to hypergeometric function

The boundedness and the accurate norm of a class of integral operator related to hypergeometric function are discussed by using the theory of hypergeometric function and Schurs test. The establishment of the main results not only builds the bridge between holomorphic Forelli-Rudin type theorem and harmonic Forelli-Rudin type theorem, but also deepens the understanding of the Bergman projection and Berezin transform.

Criteria of psychological health of adolescents with orthopedic diseases

Introduction. The task of preserving the psychological health of children and adolescents is recognized as most important in the complex conditions of the modern world. Interdisciplinary research addresses the psychological aspects of mental health. For psychological health, understanding the highest level of mental health is an integral characteristic of the well-being of the individual, and the prerequisites for the development of personal maturity. Among the adverse factors in relation to mental and psychological health is what is known as somatic suffering, which occurs in orthopedic diseases. Cognitive, emotional, and behavioral responses to orthopedic disease, eliminating maladaptive manifestations in difficult life situations due to the disease, can be important indicators of psychological health of adolescents.
 Aim. We identify specific indicators of psychological health in adolescents with various orthopedic diseases.
 Materials and methods. The study involved 90 adolescents: 60 aged 1217 years with orthopedic diseases (30 with articular juvenile chronic arthritis and 30 with long-term consequences of mechanical trauma of the upper and lower limbs, resulting from an accident due to negligence) and a control group consisting of healthy adolescents of the same age. The characteristics of the self-esteem personality component (satisfaction with various aspects of their own lives) in adolescents with orthopedic diseases and their healthy peers were considered traditional indicators of psychological health. We used PiersHarris scale modified by V.I. Gordeev Y.S. Aleksandrovich and test of attitude to disease.
 Results. In adolescents with various forms of orthopedic disorders, the formation of stable variants of the attitude to the disease with a violation of adaptation of inter- and intrapsychic types is accompanied by the experience of discomfort, difficulties of self-regulation during treatment, and signs of a negative attitude. Formation of stable variants of emotional, cognitive, and behavioral responses without expressed disorders of mental and social adaptation is accompanied by a feeling of comfort and self-satisfaction. The prevailing reaction at harmonic, allopathic, and anosognosic types of mogutt act as a sanogenic effect. Emerging resistant variants of the attitude to the disease with a violation of adaptation of inter- and intrapsychic types can represent risk factors for breach of psychological health in adolescents with orthopedic diseases.

A Theory for Harmonics Created by Resonance in Converter-Grid Systems

This letter presents a theory for the creation of harmonics by resonance in converter-grid systems. A harmonic of this type is usually not present or observable under normal operation, but may suddenly appear, with a growing magnitude and at a frequency that coincides with a system resonance frequency. The growth may be unbounded, leading eventually to a shutdown of the converter or other components in the system due to protection or physical damage, but often it stops after certain time and the harmonic sustains itself at a constant magnitude. The latter is the focus of this work and is identified as a result of system operation changing from an initially unstable mode to a critically stable mode achieved via a self-adjusting process. Small-signal sequence impedance models are used to explain this self-adjusting process and to determine the resulting harmonic responses. Experimental measurements are presented to validate the theory and to demonstrate the characteristics of this new type of harmonics.

Oscillating about coplanarity in the 4 body problem

For the Newtonian 4-body problem in space we prove that any zero angular momentum bounded solution suffers infinitely many coplanar instants, that is, times at which all 4 bodies lie in the same plane. This result generalizes a known result for collinear instants ("syzygies") in the zero angular momentum planar 3-body problem, and extends to the $d+1$ body problem in $d$-space. The proof, for $d=3$, starts by identifying the center-of-mass zero configuration space with real $3 \times 3$ matrices, the coplanar configurations with matrices whose determinant is zero, and the mass metric with the Frobenius (standard Euclidean) norm. Let $S$ denote the signed distance from a matrix to the hypersurface of matrices with determinant zero. The proof hinges on establishing a harmonic oscillator type ODE for $S$ along solutions. Bounds on inter-body distances then yield an explicit lower bound $\omega$ for the frequency of this oscillator, guaranteeing a degeneration within every time interval of length $\pi/\omega$. The non-negativity of the curvature of oriented shape space (the quotient of configuration space by the rotation group) plays a crucial role in the proof.

Output feedback anti-disturbance control of input-delayed systems with time-varying uncertainties

For input-delayed systems with time-varying uncertainties in industrial applications, a robust predictor-based anti-disturbance control design is proposed in this paper based on only output measurement, which can be applied to improve system performance in the presence of constant, asymptotically stable, step, ramp, or harmonic type disturbances, typically encountered in engineering practice. A novel predictor, named state & disturbance observer–predictor (SDOP), is firstly introduced to estimate the ‘delay-free’ system state and disturbance dynamics simultaneously, with no need to store the control history as required in the existing predictor-based control methods. To allow for long input delay, another design of sequential SDOPs (SSDOPs) is proposed such that each SSDOP only needs to estimate the future system state and disturbance in terms of a specified step size for implementation. Moreover, a recursive sub-optimal H∞ design of SSDOPs is given such that the computation burden is independent of the number of SSDOPs and thus could be significantly reduced. Consequently, two anti-disturbance control schemes are developed based on an SDOP or SSDOPs to improve system performance. For the nominal system, the input delay is allowed to be arbitrarily long by increasing the number of SSDOPs. For the presence of time-varying plant uncertainties, asymptotic disturbance rejection performance can be achieved. A sufficient condition for robust stability of the closed-loop system is established in terms of matrix inequality, which can be effectively solved to determine the controller parameters. An illustrative example from the literature is used to demonstrate the effectiveness and merit of the proposed method. ,

Mathematical analysis of giving up smoking model via harmonic mean type incidence rate

This article deals with qualitative analysis of a smoking model and provides parametric conditions for controlling diseases under the influence of smoking. The model is obtained by taking into account a novel uptake function, which relates the incidence of potential smoker with occasional smoker, of harmonic mean type for the potential and occasional smokers. Introducing a new type of incidence rate, the local as well as global stabilities for the proposed model are discussed at its steady–states. Minimizing the number of individuals involved in a substance abuse in any community is very difficult task, therefore we have introduced four control variables in the controlled system. Pontrygin’s maximum principal is used to derive optimality system. Finally, the obtained results are illustrated numerically and graphically.

Global existence of the harmonic map heat flow into Lorentzian manifolds

We investigate a parabolic–elliptic system for maps (u,v) from a compact Riemann surface M into a Lorentzian manifold N×R with a warped product metric. That system turns the harmonic map type equations into a parabolic system, but keeps the v-equation as a nonlinear second order constraint along the flow. We prove a global existence result of the parabolic–elliptic system by assuming either some geometric conditions on the target Lorentzian manifold or small energy of the initial maps. The result implies the existence of a Lorentzian harmonic map in a given homotopy class with fixed boundary data.

Classification of the Type of Harmonic Source Based on Image-Matrix Transformation and Deep Convolutional Neural Network

The classification of harmonic source types is a necessary step to alleviate harmonic pollution. This study proposes a method for the harmonic source classification based on 2-D image-matrix transformation (IMT) and deep convolutional neural network (CNN). The method firstly converts the V-I waveforms of different harmonic source types into a matrix by IMT, which was then applied to express the V-I waveform of each harmonic source as an input CNN model. Thereafter, features were extracted automatically from the harmonic source IMT matrix by the CNN model. Finally, favorable results are achieved after identifying the type of harmonic source via a classifier. In case study, a number of verifications were performed on the proposed method. Moreover, compared with existing harmonic source classification methods, the proposed strategy in this study not only avoids extracting features through expert knowledge, but also reduces the amount of data required for the harmonic source classification, and achieves higher accuracy than other methods.

Мишени психологической реабилитации пациентов с ишемическим инсультом в период компенсации и реадаптации

The paper presents the results of an empirical study aimed at determining the targets for psychological rehabilitation (the type of attitude to the disease, manifestations of depression and anxiety, quality of life, and hardiness) at different stages of rehabilitation treatment required for further development of the psychological correction programs for post-stroke patients. To collect empirical data, the authors applied the following techniques: Type of Attitude to the Disease, Hospital Anxiety and Depression Scale, The 36-Item Short Form Health Survey, and Hardiness Test. Statistical data were processed through the SPSS correlation analysis. The study reveals that during the compensation period within the rehabilitation process, it is necessary to maintain the harmonic, ergopathic, and anosognosic types of response to disease, the physical and psychological components of the quality of life, and the hardiness of patients. The research determines that during the readaptation period, the rehabilitation targets include the anxious, hypochondriac, and dysphoric types of response, the manifestations of depression and anxiety, the involvement and the physical component of the quality of life that can be compensated by vitality, social functioning, control and risk acceptance, and the psychological component of the quality of life.

Estimates for solutions of Dirac equations and an application to a geometric elliptic-parabolic problem

We develop estimates for the solutions and derive existence and uniqueness results of various local boundary value problems for Dirac equations that improve all relevant results known in the literature. With these estimates at hand, we derive a general existence, uniqueness and regularity theorem for solutions of Dirac equations with such boundary conditions. We also apply these estimates to a new nonlinear elliptic-parabolic problem, the Dirac-harmonic heat flow on Riemannian spin manifolds. This problem is motivated by the supersymmetric nonlinear \sigma -model and combines a harmonic heat flow type equation with a Dirac equation that depends nonlinearly on the flow.

Driving a dissipative quantum oscillator

The open driven quantum harmonic oscillator is studied for three different possible mechanisms of driving; a generalization of the forced oscillator, driving due to a time-dependent coupling to a two-level system, and driving due to an adiabatic modulation of the frequency. The first case encompasses all possible configurations going from the standard forced harmonic oscillator to the classical pumping type of driving typically used in quantum optics. In the second case, an additional two-level system, coupled to the oscillator at a time-varying rate, is assumed and the reduced dynamics of the oscillator and the qubit is examined. In the driving due to adiabatic modulation, the dynamics of a harmonic oscillator whose frequency slowly varies in time is studied. The study done in this paper is focused on a harmonic type of driving, although the solutions are derived for an arbitrary type of driving. In all the cases, the oscillator is assumed to be in contact with a zero- or finite-temperature environment, which provides dissipation to the system. The treatment done in this paper is fully analytic and the derivation of the solutions is based on the employment of the double Fourier transform of the Wigner function.
