Designing non-Hermitian real spectra through electrostatics

Non-hermiticity presents a vast newly opened territory that harbors new physics and applications such as lasing and sensing. However, only non-Hermitian systems with real eigenenergies are stable, and great efforts have been devoted in designing them through enforcing parity-time (PT) symmetry. In this work, we exploit a lesser-known dynamical mechanism for enforcing real-spectra, and develop a comprehensive and versatile approach for designing new classes of parent Hamiltonians with real spectra. Our design approach is based on a new electrostatics analogy for modified non-Hermitian bulk-boundary correspondence, where electrostatic charge corresponds to density of states and electric fields correspond to complex spectral flow. As such, Hamiltonians of any desired spectra and state localization profile can be reverse-engineered, particularly those without any guiding symmetry principles. By recasting the diagonalization of non-Hermitian Hamiltonians as a Poisson boundary value problem, our electrostatics analogy also transcends the gain/loss-induced compounding of floating-point errors in traditional numerical methods, thereby allowing access to far larger system sizes.

The Proper Treatment of Cash Holdings in DCF Valuation Theory and Practice

Abstract The discounted cash flow (“DCF”) model is widely used for valuing corporate assets. But valuable assets that do not generate cash flows will be missed by the DCF approach. Because cash interest income is generally not included in the projected net cash flows of operating assets, the value of cash is regarded as a non-operating asset whose value must be added to the DCF enterprise value. Unfortunately, it has become standard practice on Wall Street and for the courts to exclude some amount of cash from non-operating assets on the basis that it will be used to finance the immediate operations of the business. The exclusion of so-called “operating” or “working-capital” cash is widely accepted as necessary and is recommended in virtually all valuation texts and treatises. We disagree and show that all cash should generally be added as a non-operating asset, except in unique circumstances where “wasting cash” is not earning a fair market return. We explain that excluding operating cash is correct only if either the interest income on cash is included in the net cash flows projections used to compute DCF value, or if the specific (near-term) operating expenses that will be covered by operating cash are excluded from the net cash flow projections. In either case, the full economic benefits of owning operating cash are fully reflected in the DCF enterprise value of the company, causing the DCF value to be higher by the exact amount of operating cash that is excluded. We call this the symmetry principle of operating cash. In practice, neither condition is normally met, so that all cash should generally be treated as a non-operating asset.

Micromagnetic Simulation of Saturation Magnetization of Nanocrystalline Soft Magnetic Alloys under High-Frequency Excitation

In order to explore the magnetic moment rotation in nanocrystalline soft magnetic alloys under high-frequency sinusoidal excitation, based on G. Herzer’s stochastic anisotropy theory and symmetry principle, a three-dimensional model of nanocrystalline alloy was established, and a sinusoidal alternating magnetic field with a frequency f of 1 kHz to 10 kHz and an amplitude H of 0.1 T to 0.8 T was applied to the model. The magnetic moment movement in the magnetization process is investigated at the mesoscopic and macroscopic levels by defining the magnetic moment deflection velocity ω and magnetization rate v, respectively. The results show that ω is positively correlated with the alternating magnetic field f and H, and the increase of f has a particularly significant effect on ω growth compared with the increase of H. Then the function relation between ω and f and H is obtained by fitting. In which the coefficient of f is much larger than that of H, about 2.5 times that of H. Finally, the magnetization curve is measured by an AC measuring device, and the functional relations between v and the alternating magnetic fields f and H are obtained, in which the coefficient of f is much larger than that of H, about 2.75 times that of H. This value is approximately the same as that of the ω analysis, at the same time the relative error is only 9.1%.

Creating «Teple misto platform»: how NGOS form Ivano-Frankivsk urban space

Purpose of the article. The article is devoted to the important topic: the impact of NGOs on the creating of urban space. We focused on the case of the Charity Organization Teple Misto Platform (which means “Warm City”) in Ivano-Frankivsk. This city is one of the province Ukrainian one where live about 200 000 people. However, with the help of initiative people who united around NGOs it became a progressive pleasant for investment city with creative projects and remarkable possibilities for the citizens. Methodologically, the study is based on Actor Network Theory the process of forming the urban space was investigate as the result of interaction different actors including NGO. From the point of view that every city has his own logic of development, “Teple Misto Platform” became an important element in the network, which form Ivano-Frankivsk urban space. The actor-network theory urges us to observe the principle of symmetry and consider the influence of different actors equally. Academic originality. The role of the non-government organizations in Ukrainian city has not traced correctly according to the real level of their influence. Many authors mixed the political parties and NGOs ignoring their differences and main points. However last searching (for example, by Zagoriy Foundation) showed the increasing role of NGOs in the Ukrainian society. Conclusions. During the research, we observed how important it is to have a common platform that acts as a ground and support for other, smaller initiatives. It is shown how from the activities of a few activists a force grows that is able to influence the formation of the development strategy of the entire city. This case and experience could be use with other cities from all over the world.

A Mirror Detection Method in the Indoor Environment Using a Laser Sensor

When laser scanning is performed in some indoor environment, because of the mirror reflection problem, the exact information of the scene cannot be restored. In this paper, a method to detect the mirror based on mirror symmetry principle is proposed. By finding the corresponding relationship between the actual object and its image in the mirror, the position of the mirror could be determined without integrating any other sensor information.

The electroweak standard model

After introducing the basic symmetry principles, the full Lagrangian is derived in detail and the most relevant aspects of the electroweak phenomenology are discussed with special emphasis on the determination of the input parameters and the consistency checks of the model.

Data-Driven Model Predictive Control for Wave Energy Converters Using Gaussian Process

The energy harvested by an ocean wave energy converter (WEC) can be enhanced by a well-designed wave-by-wave control strategy. One of such superior control methods is model predictive control (MPC), which is a nonlinear constrained optimization control strategy. A limitation of the classical MPC algorithm is its requirement of an accurate WEC dynamic model for real-time implementation. This article overcomes this challenge by proposing a data-driven MPC scheme for wave energy converters. The data-based WEC model is developed by a Gaussian process (encompassing mean predictions and symmetric uncertainties) for a more accurate description of nonlinear and unmodeled system dynamics. A cross-entropy solver for data-driven MPC is employed for rapid, high-performance results, which samples trajectories from Gaussian distributions based on the concept of the symmetry principle. The proposed strategy is verified numerically by simulations which demonstrate its superior performance over a classical complex-conjugate controller.

A Double-Layer Patch Antenna for 5-6 GHz Wireless Communication.

This paper proposes a compact double-layer microstrip patch antenna with a wide bandwidth of 4.83–6.1 GHz and a gain reaching 4.7 dBi. By folding its mirror image through the electric field symmetry principle of the microstrip antenna, its electrical properties are maintained, and the physical size is halved to the compact size of only 25 × 40 mm2. The proposed antenna has the radiation characteristics of a planar inverted-F antenna (PIFA), which can generate the first resonant frequency and realize omnidirectional radiation characteristics. By coupling and feeding the upper patch, the second resonant frequency of the proposed antenna is produced and the directional radiation characteristics of the microstrip patch antenna can be achieved. The consistency of the results between the simulation and test indicates that the proposed antenna design is an ideal potential choice for home wireless local area network (WLAN) communication.

Influence of Elastic–Plastic Deformation on the Structure and Magnetic Characteristics of 13Cr-V Alloyed Steel Pipe

The principle of symmetry is one of the general methodological principles of science. The effects of any external influences, such as deformation, stresses, temperature, etc., could lead to the anisotropy (asymmetry) of properties in constructional materials. During operation, metal structures and machine parts are exposed to time-varying external mechanical loads, which can cause changes in the metal structure, the initiation of cracks, and, as a result, the destruction of the product. The application of nondestructive testing methods prevents changes in the stress–strain state and, consequently, the destruction of the object. This article contains the results of studying the effects of elastic–plastic deformation by uniaxial tension and torsion on the change in the structure and magnetic parameters of low-alloy 13Cr-V pipe steel. Modern methods of metallography and magnetic nondestructive testing methods were used as part of this study. The results of the EBSD analysis showed that deformation during torsion, in contrast to uniaxial tension, is unevenly distributed over the sample cross section. In the cross section of the sample, the most severely deformed grains with a change in their geometry are observed near the surface; in the center, there is no change in geometry. During tension, the deformation over the cross section of the sample is uniformly distributed. Correlations between the applied normal and tangential stresses and magnetic characteristics of the 13Cr-V structural steel were determined. Informative parameters that could be used for the development of nondestructive testing methodologies for solving concrete tasks were determined. Different methods of deformation lead to diverse structural changes in grain structure.

Symmetry in World-Historic Perspective: Reply to Lynch

Abstract William Lynch has persistently questioned the politics underlying my appeal to science and technology studies’ flagship symmetry principle. He believes that it licenses the worst features of the ‘post-truth condition’. I respond in two parts, the first facing the future and the second facing the past. In the first part, I argue that the symmetry principle will be crucial in decisions that society will increasingly need to make concerning the inclusion of animals and machines on grounds of sentience, consciousness, intelligence, etc. In the second part, I argue that the symmetry principle has been in fact at the core of the ‘justice as fairness’ idea that has been at the core of both liberal and socialist democracies. Difficulties start once the means of expression and communication are made widely available and the standards of fairness are subject to continual questioning and renegotiation.

Does Post-truth Expand or Restrict Political Choice? Politics, Planning, and Expertise in a Post-truth Environment

Abstract Steve Fuller has replied to my critique of his endorsement of a post-truth epistemology. I trace the divergence in our approach to social epistemology by examining our distinct responses to the principle of symmetry in the sociology of scientific knowledge. Fuller has extended the concept of symmetry and challenged the field to embrace a post-truth condition that flattens the difference between experts and the public. By contrast, I have criticized the concept of symmetry for policing the field to rule ideology critique out of court. I argue that a focus on post-truth populism obscures the role of counter-elites and ideologies that restrict political choice. A better way to promote democracy would be to support minority positions within science that promise to open up suppressed political possibilities and to seek the coordinated use of different disciplines to address significant public problems.

К формированию модели слуховой функции в задаче освещения окружающей обстановки

The large-scale-temporal representation of acoustic signals and technical solutions for their processing, allowing visualization of the environment in conditions of limited visibility using the operator's auditory analyzer, are considered. The principle of symmetry of physical laws is extended to the processing of signals from objects that are the purposes of detection and classification. Mod-els of scale-time representation of acoustic signals and their processing for visualization of the scene by the operator are proposed.

Infinitesimal reference frames suffice to determine the asymmetry properties of a quantum system

Symmetry principles are fundamental in physics, and while they are well understood within Lagrangian mechanics, their impact on quantum channels has a range of open questions. The theory of asymmetry grew out of information-theoretic work on entanglement and quantum reference frames, and allows us to quantify the degree to which a quantum system encodes coordinates of a symmetry group. Recently, a complete set of entropic conditions was found for asymmetry in terms of correlations relative to infinitely many quantum reference frames. However, these conditions are difficult to use in practice and their physical implications unclear. In the present theoretical work, we show that this set of conditions has extensive redundancy, and one can restrict to reference frames forming any closed surface in the state space that has the maximally mixed state in its interior. This in turn implies that asymmetry can be reduced to just a single entropic condition evaluated at the maximally mixed state. Contrary to intuition, this shows that we do not need macroscopic, classical reference frames to determine the asymmetry properties of a quantum system, but instead infinitesimally small frames suffice. Building on this analysis, we provide simple, closed conditions to estimate the minimal depolarization needed to make a given quantum state accessible under channels covariant with any given symmetry group.

Metaphor of the labyrinth in the musical culture of the second half of the XX century: ballet "Labyrinths" by A. Schnittke

The metaphor of the labyrinth in the second half of the XX century becomes an iconic model of the postmodern world order. In musical culture, the phenomenon of the labyrinth has acquired the meaning of a symbol of intertextuality, a game with cultural codes and musical heritage of the past, multivariance, variability, uncertainty. The ballet "Labyrinths" by Alfred Schnittke is an example of the embodiment of the labyrinth paradigm and is the object of research. The subject of the study is the peculiarity of the implementation of the idea of the labyrinth at the compositional and dramatic level of the ballet cycle. In the light of the author's individual interpretation, the labyrinth model takes the form of a "macrolabirint" and a "microlabiint", where the macrostructure is the construction of the whole, and the microstructure is the last, fifth part. The novelty of the research lies in the consideration of the compositional and dramatic features of the ballet "Labyrinths" in the context of the metaphor of the labyrinth. The concept of the "macrolabyrint" contributed to the relief display of the principles of symmetry and centralization inherent in the labyrinth of the classical Cretan type. Symmetry in the ballet cycle found expression in the structure of the extreme parts, in their author's division into sections, the presence of a reprise in Maestoso and Meno mosso, a single tonal organization interspersed with modal episodes, the assertion of the third c–e in the intonation system of the parts. Centralization of the Cretan labyrinth was reflected in the endowment of the fourth part with the properties of the culmination point, characterized by an increase in sonorous qualities, an abundance of cluster verticals, and heterogeneous stratified tissue. The concept of "microlabirint" contributed to the depiction of the multivariance of the maze-confusion in the fifth part of the ballet. The nonlinear movement of the characters along the branched labyrinth model was carried out by the interaction of contrasting sections correlated with deviation into various emotional states. The conducted research allowed us to conclude about a new interpretation of the labyrinth paradigm in ballet in the light of Schnittke's individual author's handwriting.

A new reverse Hardy\u2013Hilbert inequality with the power function as intermediate variables

In this paper, by virtue of the symmetry principle, applying the techniques of real analysis and Euler–Maclaurin summation formula, we construct proper weight coefficients and use them to establish a reverse Hardy–Hilbert inequality with the power function as intermediate variables. Then, we obtain the equivalent forms and some equivalent statements of the best possible constant factor related to several parameters. Finally, we illustrate how the obtained results can generate some particular reverse Hardy–Hilbert inequalities.

Participatory research in institutional contexts: achieving ethical symmetry in research practice

ABSTRACT The article examines the question of asymmetries in participatory research relationships in institutional contexts. The principle of ethical symmetry forms the theoretical framework for the investigation. It draws on experience from three (participatory) research projects in different settings, involving academics and people living in the settings as co-researchers. The central methodological tool is a research process model used to systematically dissect the research process and its progress over time. The three-step empirical analysis was structured as follows: First, building on Foucault’s concept of the dispositif, we discuss the invocations experienced by the academic and co-researchers. Secondly, we investigate how the actors handled the invocations, adopting a relational understanding of agency. Finally, we integrate the two perspectives to explore the possibilities of achieving ethical symmetry. The article concludes with reflections – drawing on the findings from the three case studies – on the impact of the principle of ethical symmetry on social work practice and research.

Du libre et du lié dans les références doctrinales et nominales de Jakobson et de Troubetzkoy

Pierre CAUSSAT, University of Paris-X Nanterre : « On the Doctrines Referred to in Jakobson's and Trubetzkoy's Work : Bound or Unbound references »
 One of the peculiarities characteristic of R. Jakobson's work is the numerous doctrinal quotations derived from Russian culture, as well as from Western culture. In fact, their apparent eclecticism is implicitly based on a well-defined «axiom of choice» : the presence – or absence ­– in the doctrines referred to of principles of order, symmetry and system. This axiom is strongly linked with the most constant stock of the «Russian tradition» liable, in every field, to sort out and claim its own.

Investigating Cohesiveness of QS. Al-Mā’idah: A Review on Michel Cuypers Implementation of Semitic Rhetorical Analysis (SRA)

This article examines Michel Cuyper’s interpretation of the Qur’an which is the result of the application of Semitic Rhetorical Analysis (SRA) in QS. Al-Mā’idah. Although SRA’s implementation has demonstrated the coherence of the Qur’anic text; however, no one has properly articulated the cohesiveness of the Qur’anic text as the basis of that coherence. Thus, to ascertain the text’s cohesiveness in terms of positions and forms from the SRA’s perspective, this study applied cohesion text theories to Cuypers’ implementation of SRA in QS. Al-Mā’idah. A thesis of the paper is that, according to SRA, the cohesiveness of a qur’anic text in QS Al-Mā’idah can be shown through the pairings of words or sentences inside particular groupings of text particles following the principles of Semitic Rhetoric. The Semitic Rhetoric’s principle of parallel, concentric, or mirror symmetry in those text particle groups determined which words or phrases are paired in a text particle group. As a result, from an SRA perspective, the Qur’anic text’s cohesiveness may be discovered at each level of the text particle group, demonstrating multi-layered cohesiveness. In Cuypers’ reading of QS Al-Mā’idah, synonyms and repetition are used to maintain lexical cohesion, while ellipsis, substitution, and reference established grammatical cohesion.

Enstrophy from symmetry

We study symmetry principles associated with the approximately conserved enstrophy current, responsible for the inverse energy cascade in non relativistic 2+1 dimensional turbulence. We do so by identifying the accidental symmetry associated with enstrophy current conservation in a recently realized effective action principle for hydrodynamics. Our analysis deals with both relativistic and non relativistic effective actions and their associated symmetries.
