Considering recent advancements in the nonlinear pulse-echo technique, understanding reflected nonlinear waves from inaccessible edges and surfaces becomes important. A unique geometrical model solved numerically using the finite element method is proposed and studied via extensive numerical experiments to gain insight into harmonically scattered waves from different shapes of the 2-D spaced corners considering the challenges of theoretical solutions that can capture the interplay between multiple phenomena. Tang et al. (2012), Kube (2017-18), and Achenbach and Wang (2017-18) studied the harmonic scattering of waves from nonlinear inclusions using analytical techniques. Linear longitudinal waves scattered from the triangular, circular, and rectangular-shaped free and fixed edges of the 2-D spaced corner show mode conversion and energy transfer between bulk wave modes at fundamental frequencies. The interaction of nonlinear ultrasonic waves with the edges makes things complex due to an interplay between harmonic generation, linear scattering, harmonic scattering, bulk wave mode conversion, and harmonic energy redistribution between all harmonics of the scattered longitudinal and transverse waves. This results in non-intuitive interesting responses. These studies are extended to explore one-way and two-way two-wave mixing of longitudinal waves and their interesting nonlinear effects. Phase difference introduced during harmonic scattering distinguishes the sensitivity of fundamental harmonics.

The power quality of the Electrical Power System (EPS) is greatly affected by electrical harmonics. Hence, accurate and proper estimation of electrical harmonics is essential to design appropriate filters for mitigation of harmonics and their associated effects on the power quality of EPS. This paper presents a novel statistical (Least Square) and meta-heuristic (Grey wolf optimizer) based hybrid technique for accurate detection and estimation of electrical harmonics with minimum computational time. The non-linear part (phase and frequency) of harmonics is estimated using GWO, while the linear part (amplitude) is estimated using the LS method. Furthermore, harmonics having transients are also estimated using proposed harmonic estimators. The effectiveness of the proposed harmonic estimator is evaluated using various case studies. Comparing the proposed approach with other harmonic estimation techniques demonstrates that it has a minimum mean square error with less complexity and better computational efficiency.

The inverted U hypothesis in music predicts that listeners prefer intermediate levels of complexity. However, the shape of the liking response to harmonic complexity and the effect of musicianship remains unclear. Here, we tested whether the relationship between liking and harmonic complexity in single chords shows an inverted U shape and whether this U shape is different for musicians and non-musicians. We recorded these groups’ liking ratings for four levels of harmonic complexity, indexed by their level of acoustic roughness, as well as several measures of inter-individual difference. Results showed that there is an inverted U-shaped relationship between harmonic complexity and liking in both musicians and non-musicians, but that the shape of the U is different for the two groups. Non-musicians’ U is more left-skewed, with peak liking for low harmonic complexity, while musicians’ U is more right-skewed, with highest ratings for medium and low complexity. Furthermore, musicians who showed greater liking for medium compared to low complexity chords reported higher levels of active musical engagement and higher levels of openness to experience. This suggests that a combination of practical musical experience and personality is reflected in musicians’ inverted U-shaped preference response to harmonic complexity in chords.

The purpose of this study was to investigate the relationships between music training and musical complexity and focus of attention to melody or harmony. Participants ( N= 192) were divided into four groups: university jazz majors ( n= 64), other university music majors ( n= 64), high school instrumentalists ( n= 32), and junior high instrumentalists ( n= 32). The musical complexity variable consisted of four levels of melodic complexity and four levels of harmonic complexity each paired for a total of 16 possible combinations all heard by each participant. Each trial consisted of a melodic complexity/harmonic complexity pairing performed by the same performer on jazz piano. Subjects indicated their overall perceived focus of attention for melody or harmony either during or immediately after they listened. A four-factor ANOVA was conducted with two between-subjects factors (order and music-training groups) and two within-subjects factors (melodic complexity and harmonic complexity). Significant differences were found for focus of attention for both melodic complexity and harmonic complexity. Significant interactions occurred between music training and focus of attention. Overall, data showed that as music training increases, so does harmonic focus of attention. March 11, 2005 October 4, 2005

This paper presents a current suppression method based on a droop control strategy under distorted grid voltage with inter-harmonics and fundamental frequency fluctuation. In this proposed strategy, the current incomplete derivation controller is employed to decrease the negative impact caused by harmonic and inter-harmonic grid voltage. This method provides a good dynamic response and has low complexity against the inter-harmonics with unfixed fundamental frequency. Based on a mathematical model of the grid-connected inverter, we designed novel instantaneous frequency detection and feed-forward methods to suppress the grid fundamental frequency fluctuation impacts. Then the main parameters were analyzed. The simulation and experimental results verified the feasibility and effectiveness of the proposed method.

Abstract The direction, density, and diffusivity of light are important indicators of spatial characteristics in describing a three-dimensional light environment. Mury presented a method for describing, measuring, and visualizing the structure of light fields using spherical harmonics in terms of changes in the density and direction of light in three-dimensional space. We extended this study by using higher-order spherical harmonics, which would represent more diverse characteristics of the light environment. We also quantitatively described the light environment as numerical values and investigated the correspondence between these numerical values and human perceptual quantities. As a result, we confirmed that there is a certain degree of correspondence between the “complexity” quantified by the spherical harmonic and the “complexity” perceived by people when observing real space.

Abstract In this paper, a harmonic distortion measurement algorithm and its system design based on time-domain matrix operations are proposed, which can quickly calculate the harmonic amplitudes, phases and total harmonic distortion of a signal. To realize the calculation of harmonic signal parameters in the time domain, we proposed a method to convert the nonlinear function representing the signal into a linear function, constructed a matrix equation, and solved the equation by the row transformation method, which significantly reduced the complexity of the algorithm. Finally, based on the proposed algorithm, a system design was implemented by the digital signal processing theory, and the measurements showed that the system achieves an amplitude error of nearly 1% and a THD error of less than 0.3% when measuring the generated 10 kHz fundamental with 5-order harmonics. The system can be used to measure and calculate the amplitudes and THD of harmonic distortion signals with high precision.

Because of The low complexity of passive filters (PF) compared to the active filter, their high efficiency, their ease of installation and their different topologies,theyremained the devices required in the power system. In order to minimize the harmonic distortion produced by the large industrial loads, harmonic filters should, therefore, be designed with the utmost rigor, because a poorly designed filter may amplify the undesired harmonics. The determination of the PFcomponents requires both adetailed study ofthe power system parameters, which influence the efficiency and economic viability of the harmonic compensation and the reactive power required by the load.This article studies the use of the Cuckoo optimization algorithm (COA), in order to designpassive filters with an improved power quality and reduced cost. The optimal filters are connected concurrently to the power system so that each individual Harmonic distortion respects the recommended limits. The results show that the optimized (PF) is effective, and has a lower cost.

À partir de l’application répétée de l’opérateur somme à certaines séquences, en ce qui concerne leur longueur (appelée période), on observe des comportements intéressants et des propriétés mathématiques récurrentes. Certaines observations ont été faites par Anatol Vieru lui-même dans [18] : il a observé que la période des séquences tend généralement à augmenter quand on applique l’opérateur de somme, et pour certaines séquences cela reste toujours une puissance de 2. En outre, pour des séquences spécifiques, il y a des valeurs qui ont tendance à proliférer. La première formalisation mathématique a été faite par D.T. Vuza en 1982 ( [19]) et en [2] ont été présentés les résultats fondamentaux sur la décomposition en séquences idempotente et nilpotente (appelées réductibles et reproductibles respectivement). Dans[4] le problème de la prolifération de certaines valeurs dans les primitives de la séquence [2, 1, 2, 8, 4, 4, 8] P12 was studied in a computational way a été∈ étudié. Plus récemment, in [13] le formalisme des automates (cellular automata) a été utilisé pour étudier les propriétés duales de l’opérateur ∆. Nous résumons ici la théorie des séquences périodiques à valeurs modulairesdéveloppée jusqu’à présent et présentons les résultats obtenus sur la période des primitives et sur la prolifération des valeurs. Les résultats principaux (Lemma 1.3.5, Proposition 1.5.10, Theorems 1.5.6, 1.5.9 and 2.2.1, Section 2.3.2, Section 2.4) font partie d’un travail conjoint avec Luisa Fiorot et Alberto Tonolo (voir [8, 9]). L’homologie persistante a été utilisée dans la recherche mathématique et musicale, dans le but de relier les caractéristiques topologiques des codes-barres aux propriétés musicales des ensembles de données. En particulier, dans [23] l’homologie persistante est utilisée avec le Tonnetz pour le classement automatique des styles. Dans [24], la filtration Vietoris-Rips est utilisée pour calculer l’homologie persistante d’une partition de musique et pour afficher les caractéristiques thématiques des morceaux de musique Nous nous concentrons sur l’harmonie et, plus précisément, sur la complexité harmonique. Comme en [23], l’objectif est de reconstituer les propriétés harmoniques (densité harmonique) des séquences d’accords associées à des morceaux de musique. Nous utilisons deux bases de données musicales ([33, 26]) qui contiennent l’analyse harmonique du corpus des Beatles et de plusieurs corpus de musique classique respectivement. Par rapport à [23], nous abandonnons le Tonnetz au profit d’un objet plus souple : un graphe d’accords. Cela nous permet de modifier librement les relations entre les accords et aussi de considérer des distances non symétriques entre eux. Ce dernier aspect joue, à notre avis, un rôle central dans les progressions harmoniques, car il décrit bien l’asymétrie temporelle de la perception humaine de l’harmonie. Pour construire des complexes simpliciaux sur des graphes orientés, donc sans avoir une distance symétrique, nous utilisons la filtration Dowker, dont les avantages ont été présentés dans [22, 25]
From the repeated application of the sum operator to certain sequences, regarding their length (called period), interesting behaviors and recurrent mathematical properties are observed. Some observations were made by Anatol Vieru himself in [18]: he observed that the period of sequences generally tends to increase when applying the sum operator, and for some sequences it still remains a power of 2. In addition, for specific sequences, there are values that tend to proliferate. The first mathematical formalization was made by D.T. Vuza in 1982 ( [19]) and in [2] were presented the fundamental results on the decomposition into idempotent and nilpotent sequences (called reducible and reproducible respectively). In[4] the problem of the proliferation of certain values in sequence primitives [2, 1, 2, 8, 4, 4, 8] P12 was studied in a computational way was studied. More recently, in [13] the formalism of automata (cellular automata) has been used to study the dual properties of the operator . Here we summarize the theory of periodic sequences with modular valuesdeveloped so far and present the results obtained on the period of primitives and on the proliferation of values. The main results (Lemma 1.3.5, Proposition 1.5.10, Theorems 1.5.6, 1.5.9 and 2.2.1, Section 2.3.2, Section 2.4) are part of a joint work with Luisa Fiorot and Alberto Tonolo (see [8, 9]). Persistent homology has been used in mathematical and musical research, in order to link the topological characteristics of barcodes to the musical properties of data sets. In particular, in [23] the persistent homology is used with the Tonnetz for automatic classification of styles. In [24], the Vietoris-Rips filtration is used to calculate the persistent homology of a musical score and to display the thematic characteristics of musical pieces. As in [23], the objective is to reconstruct the harmonic properties (harmonic density) of chord sequences associated with music pieces. We use two musical databases ([33, 26]) which contain the harmonic analysis of the Beatles corpus and several classical music corpus respectively. Compared to [23], we abandon the Tonnetz in favor of a more flexible object: a graph of chords. This allows us to freely modify the relationships between agreements and also to consider non-symmetrical distances between them. This last aspect plays, in our opinion, a central role in harmonic progressions, because it describes well the temporal asymmetry of the human perception of harmony. To construct simplicial complexes on oriented graphs, therefore without having a symmetrical distance, we use Dowker filtration, the advantages of which have been presented in [22, 25]

L'amélioration du contraste des images échographiques occupe une place importante en imagerie ultrasonore médicale puisque la qualité des images impacte directement le diagnostic médical. Les imageries de contraste sous et ultra-harmoniques sont deux techniques permettant de produire des images à fort contraste. Le développement de techniques de filtrage, permettant de mieux extraire les composantes sous et ultra-harmoniques présentes dans les signaux renvoyés par les produits de contraste ultrasonore, a pour conséquence d'améliorer encore plus le contraste des images. Les modèles non linéaires dits " boîtes noires " du type Volterra, Hammerstein, Wiener, sont souvent utilisés pour identifier et modéliser les systèmes non linéaires tels que les produits de contraste ultrasonore. Ces modèles, bien que très bien adaptés pour modéliser les composantes harmoniques entières, ne le sont plus en présence de sous et ultra-harmoniques. Dans les années 2000, une méthode permettant la modélisation de sous et ultra-harmoniques en utilisant un modèle de Volterra à plusieurs entrées (Muliple Input Single Output : MISO) a été développée. Pourtant, bien que cette méthode soit complètement originale dans le domaine considéré, les points clés qui la sous-tendent ne sont pas clairement identifiés. C'est en identifiant clairement les points clés de la méthode existante que nous pouvons la généraliser et proposer plusieurs nouveaux paradigmes pour la modélisation et l'extraction de sous et ultra-harmoniques. Nous proposons alors des alternatives beaucoup plus simples du type mono-entrée mono-sortie (Single Input Single Output: SISO). En modulant en fréquence l'entrée du système, nous avons pu ainsi identifier les réponses impulsionnelles des différents canaux du modèle de Hammerstein généralisé. À partir de ce cadre général, nous avons aussi proposé de nouvelles approches pour réduire la complexité du modèle de Volterra.

L’association de la bière avec les mets apparaît comme une nouvelle tendance en France. Il est donc nécessaire pour les promoteurs de bière et les professionnels de la gastronomie de fournir à leurs clients des conseils de qualité en terme d’accord bière et mets. Au vu de ce contexte, l’objectif de la thèse était d’identifier les principes d’association et de mieux comprendre les mécanismes perceptuels qui les sous-tendent. Les déterminants des accords mets et boissons ont, dans un premier temps, été identifiés à partir du discours d’experts. Les résultats ont montrés que les associations mets et boissons sont régies par des caractéristiques perceptuelles, conceptuelles et affectives, liées à des mécanismes physico-chimiques, perceptuels et cognitifs. Les experts ont souvent mentionné la «similarité aromatique» comme l'un des principaux principes d'association. Ce principe consiste à associer deux produits partageant des arômes similaires. Les mécanismes perceptuels sous-jacents à ce principe ont été investigués. Les résultats ont montrés qu’une similarité aromatique entre un mets et une boisson augmente le niveau d’harmonie et d’homogénéité de leur association et diminue sa complexité. Ces effets peuvent être renforcés en orientant l’attention du dégustateur sur l’arôme partagé. D’un point de vue théorique, cette thèse conclut que l’association bières et mets inclut des dimensions sensorielles avec une recherche d’harmonie, mais aussi des dimensions symboliques et contextuelles. D’un point de vue plus appliqué, cette thèse fournit aux professionnels de la gastronomie, de nouvelles informations concernant les mécanismes perceptifs sous-tendant les principes d’associations
Pairing between beer and dishes emerges as a new trend in France. Beer promoters or gastronomy professionals need to offer high-quality advices in terms of beer and food pairing to their customers. Within this context, the objective of the research was to identify pairing principles and to better understand the underlying perceptual mechanisms. Determinants of food and beverage pairing were first analysed from experts’ discourses. Results showed that food and beverage pairings are governed by perceptual, conceptual and affective features, related to physio-chemical, perceptual and cognitive processes. Experts often mentioned “Aromatic Similarity” as one of the main pairing principles. This “Aromatic similarity” principle consists in matching two products sharing similar aromas. Underlying perceptual mechanisms were then investigated. Results showed that aromatic similarity in food and beverage generally increases harmony and homogeneity and decreases complexity of the match. These effects can be reinforced by orientating the attentional focus on the shared aroma. From a theoretical point of view, this work concludes that beer and food pairing includes sensory dimensions with the search for harmony, as well as symbolic and contextual dimensions. From an applied point of view, this work provides useful information to gastronomy professionals with recent knowledge on perceptual mechanisms underlying food and beverage pairing principles

Les années soixante ont laissé libre expression aux pionniers d’une musique nouvelle — leurs expérimentations et l’avènement de la musique électroacoustique ont fait apparaître d’innombrables formes et théories qui ont définitivement changé les fondements du langage de la musique savante et la façon dont on l’aborde. Face à la musique contemporaine on se trouve dans une impasse quand on cherche à expliquer, par une démarche analytique classique, les interactions complexes de cette musique qui produisent des formes et des sons inédits. Nous cherchons à éviter cette impasse en nous appuyant sur une méthodologie innovante fondée sur les théories de la systémique, approche adoptée par les sciences contemporaines parce qu’elle donne priorité au qualitatif sur le quantitatif. Appliquée à une œuvre qui intègre les éléments électroacoustiques en interaction avec les instruments traditionnels, cette méthodologie nous permet de dégager et d’expliquer les processus qui permettent au compositeur d’intervenir à l’intérieur même du son et de créer les illusions et les paradoxes sonores, autrement dit, les émergents. L’objet de cette analyse sera l’approche de la composition de Gérard Pape, artiste singulier, pour lequel, l’énergie musicale est une force transcendante. Sa vision innovante de la composition contemporaine intègre la notion d’émergence dans une écriture complexe et dynamique. Les paradoxes sonores frappent l’auditeur alors qu’ils échappent en partie à l’écriture de la partition. Nous cherchons à dégager les éléments définis par la partition au regard des effets dits « émergents » produits par l’interrelation dynamique de ces éléments. En utilisant la systémique comme approche d’analyse musicale, nous voulons développer une approche transversale qui permet de souligner l’apparition de structures et de propriétés nouvelles, proches de celles du vivant. Par elles, l’écriture musicale explose pour aller, comme en témoigne l’œuvre de Gérard Pape, de l’harmonie au chaos
The free expression of the sixties gave rise to a generation of pioneers that we now call the avant-garde. The arrival of electroacoustic music fuelled their experimentation and as a result, numerous new musical genres and theories appeared which have not only changed the language of music at a fundamental level, but have also redefined the ways we perceive it. Contemporary music now finds itself confronted by an analytical dilemma. The limits of a traditional approach simply don’t take into account the complex interactions in this music that are responsible for its unusual forms and original sounds. We hope to resolve this dilemma by integrating an innovative methodology based on systems theory, a scientific approach that takes into account the qualitative aspects of scientific problems, reason for which it has gained momentum over the past thirty years. By applying this approach to a musical work we aim to develop a methodology that will permit us to explain the process by which the composer intervenes at the molecular level of sound and thus creates illusions and musical paradoxes, which we might consider emergent effects. The objective of this analysis is to gain an understanding of Gerard Pape’s particular musical approach, for whom musical energy seems to be a transcendental force. His innovative musical vision engages the principles of emergence in the dynamic complexity of his writing. Sonic paradoxes strike the listener but are less evident to transcribe into a musical score. We hope to find a link between the notated score and the emergent effect produced by the dynamic interrelations of its content. By undertaking a systems approach to musical analysis, we hope to develop a transversal model that will enable us to highlight the elusive new structures and properties that seem to grow out of this process. In Pape’s music, these emergent features distort the musical surface, and although engendered by the score, seem to burst out of nowhere, leading the listener from harmony into chaos

This study aims to explore the complexity of chord progressions and its application to the automatic accompaniment system. Experiment was conducted to verify the harmony complexity by general public. To make a better accompaniment with melody, we use harmony complexity to control music accompaniment texture. In addition, we propose DCPA (Dual Chord Progressions Algorithm) automatic accompaniment system, which is divided into four parts: key finding, chord analysis, chord select algorithm, and pattern accompaniment system. To improve the versatility of system, we establish the rule of chord function to make the chord progressions comply with the rules. In pattern accompaniment system, users can add a variety of different patterns accompaniment, so that the automatic accompaniment sounds richer. Researchers can make more chord-select rules and patterns to coordinate specific music style in the future work.

Of the many composers in the Western classical tradition who celebrated the marriage between psyche and sound, those explored in this book followed the lines diverging from Wagner in philosophizing the nature of desire in music. This book offers two new theories of tonal functionality in the music of the first half of the twentieth century that seek to explain its psychological complexities. First, the book further develops Riemann’s three diatonic chord functions, extending them to account for chromatic chord progression and substitution. The three functions (tonic, subdominant, and dominant) are compared to Jacques Lacan’s twin concepts of metaphor and metonymy, which drive the apparatus of human desire. Second, the book develops a technique for analyzing the drives that pull chromatic music in multiple directions simultaneously, creating a libidinal surface that mirrors the tensions of the psyche found in Schopenhauer, Freud, and the post-Freudians Lacan, Lyotard, and Deleuze. The harmonic models are tested in psychologically challenging pieces of music by post-Wagnerian composers. From the obsession with death and mourning in Suk’s Asrael Symphony to an exploration of “perversion” in Strauss’s Elektra, from the post-Kantian transcendentalism of Ives’s Concord Sonata to the “Accelerationism” of Skryabin’s late piano works, and from the Sufi mysticism of Szymanowski’s Song of the Night to the failed fantasy of the American dream in Copland’s The Tender Land, the book cuts a path through the dense forests of chromatic complexity and digs deep into the psychological makeup of post-Wagnerian psychodynamic music.

In modernist music, disability functions as an artistic resource: a source of images and an impetus for narrative. Disability enables musical modernism. Modernist music is centrally concerned with the representation of disabled bodies. Its most characteristic features—fractured forms, immobilized harmonies, conflicting textural layers, radical simplification of means in some cases, and radical complexity and hermeticism in others—can be understood as musical representations of disability conditions, including deformity/disfigurement, mobility impairment, madness, idiocy, and autism. Although modernist music embodies negative, eugenic-era attitudes toward disability, it also affirmatively claims disability as a resource, thus manifesting its disability aesthetics.

Choreographer Mark Morris is generally regarded as a supremely musical choreographer, and his respect for the musical score and his preference for working very closely with it are well known. A close reading of his works leads one to examine the nature of the relationship between what is seen and what is heard in the context of art, and in relation to one’s embodied existence. In this study ofAll Fours(2003), choreographed to Bartok’sFourth String Quartet, structural comparative analysis allows for an examination of the temporal dimension of the relationship and changes in and through time—meter, pulse, rhythm, pitch and harmony, dynamic shaping, and instrumentation. Through this, layers of complexity in the choreomusical relationships are revealed that stimulate questions concerning the interface of aural and kinetic in art, and which reveal how Morris’s work resonates with a deeply affirmative and holistic philosophy of life.

Modernist music is centrally concerned with the representation and narration of disability. The most characteristic features of musical modernism—fractured forms, immobilized harmonies, conflicting textural layers, radical simplification of means in some cases, and radical complexity and hermeticism in others—can be understood as musical representations of disability conditions, including deformity/disfigurement, mobility impairment, madness, idiocy, and autism. Modernist musical representation and narration of disability both reflect and shape (construct) disability in a eugenic age, a period when disability was viewed simultaneously with pity (and a corresponding urge toward cure or rehabilitation) and fear (and a corresponding urge to incarcerate or eliminate). Disability is right at the core of musical modernism; it is one of the things that musical modernism is fundamentally about. This book draws on two decades of work in disability studies and a growing body of recent work that brings the discussion of disability into musicology and music theory. This interdisciplinary enterprise offers a sociopolitical analysis of disability, focusing on social and cultural constructions of the meaning of disability, and shifting attention from biology and medicine to culture. Within modernist music, disability representations often embody pernicious stereotypes and encourage sentimentalizing, exoticizing, or more directly negative responses. Modernist music claims disability as a valuable resource, but does so in a tense, dialectical relationship with medicalized, eugenic-era attitudes toward disability.

Suffering is an unavoidable reality in healthcare. Not only are patients and families suffering but also the clinicians who care for them. Commonly the suffering experienced by clinicians is moral in nature, in part a reflection of the increasing complexity of health care, their roles within it, and the expanding range of available interventions that challenge their moral foundations. Moral suffering is the anguish that arises occurs in response to moral adversity that challenges clinicians’ integrity: the inner harmony that arises when their essential values and commitments are aligned with their choices and actions. The sources and sequelae of moral distress, one type of moral suffering, have been documented among clinicians across specialties. Transforming their suffering will require solutions that expanded individual and system strategies. Moral resilience, the capacity of an individual to restore or sustain integrity in response to moral adversity, offers a path forward. It encompasses capacities aimed at developing self- regulation and self-awareness, buoyancy, moral efficacy, self-stewardship and ultimately personal and relational integrity. Whether it involves gradual or profound radical change clinicians have the potential to transform themselves and their clinical practice in ways that more authentically reflect their character, intentions and values. The burden of healing our healthcare system is not the sole responsibility of individuals. Clinicians and healthcare organizations must work together to transform moral suffering by cultivating the individual capacities for moral resilience and designing a new architecture to support ethical practice. Used worldwide for scalable and sustainable change, the Conscious Full Spectrum approach, offers a method to solve problems to support integrity, shift patterns that undermine moral resilience and ethical practice, and leverage the inner potential of clinicians and leaders to produce meaningful and sustainable results that benefit all.

A one-dimensional free-electron laser code has been written that includes harmonic generation. In this code the electrons are driven by a spatially-averaged superposition of the fundamental and its overtones. The waves are driven by the Fourier-analyzed transverse current. The initial wave amplitude at all harmonics originates from a stochastic placement of particles. We show that when the overtones are small compared to the fundamental, a self-consistent description is not necessary, thereby reducing the computational complexity.

This electronic resource contains a critical summary of the problems of sovereign statehood and the responsibility of public authority in the light of an interdisciplinary systemic organic approach. The author reveals the essence and content of the categories “sovereign statehood” and “responsibility of public authority” as key factors of the state legal system for ensuring the life of the Russian Federation in the conditions of the emergence of a new world order. It is shown that the multi-valued category of “statehood” (statehood, stateness, nationhood, nationness) reflects the complexity of the concept, which characterizes the status and ability of the state to carry out its functions, and on the other hand, reflects the cultural-historical and spiritual-ideological unity of society, which is the deepest internal semantic content both preceding the state and completing its sociohistorical formation in the course of state development and historical transformations. Based on the systemic-organic approach and within the framework of the structure of the Aristotelian tetrad, the author reveals an integral model of the political and legal phenomenon of “statehood”, in which the final cause (ethion) is determined by “sovereign statehood”, which presupposes unity, integrity, actual autonomy, independence, independence and self-sufficiency states in making decisions that ensure the historical existence and development of the country. The work presents a theoretical understanding of social (public) solidarity as a legal construct and instrument of social harmony and integrity of the state-legal body of the Russian Federation. It is shown that public solidarity, as a constitutional and administrative-legal phenomenon in its positive and negative forms, creates the necessary basis for the implementation of the principle of mutual responsibility of the individual, society and state. An idea of the responsibilities of the state, its bodies and officials to the individual and society is given, the role and place of public legal responsibility of holders of power in the solidary social mechanism is outlined. In general, the results of interdisciplinary research are aimed at identifying key factors in social theory and practice that contribute to the acquisition of true independence and self-sufficiency of Russian statehood and the preservation of the civilizational foundations of a multinational Russian society. The manual will be useful to undergraduate and graduate students studying social and political sciences, and anyone interested in the theory and practice of government.
