A broken symmetry approach for the modeling and analysis of antiparallel diodes-based chaotic circuits: a case study

This paper focuses on the modeling and symmetry breaking analysis of the large class of chaotic electronic circuits utilizing an antiparallel diodes pair as nonlinear device necessary for chaotic oscillations. A new and relatively simple autonomous jerk circuit is used as a paradigm. Unlike current approaches assuming identical diodes (and thus a perfect symmetric circuit), we consider the more realistic situation where both antiparallel diodes present different electrical properties in spite of unavoidable scattering of parameters. Hence, the nonlinear component synthesized by the diodes pair exhibits an asymmetric current–voltage characteristic which engenders the explicit symmetry break of the whole electronic circuit. The mathematical model of the new circuit consists of a continuous time 3D autonomous system with exponential nonlinear terms. We investigate the chaos mechanism with respect to model parameters and initial conditions as well, both in the symmetric and asymmetric modes of operation by using bifurcation diagrams and phase space trajectories plots as main indicators. We report period doubling route to chaos, spontaneous symmetry breaking, merging crisis and the coexistence of two, four, or six mutually symmetric attractors in the symmetric regime of operation. More intriguing and complex nonlinear behaviors are revealed in the asymmetric system such as coexisting asymmetric bubbles of bifurcation (a new kind of phenomenon discovered in this work), hysteretic dynamics, critical phenomena, and coexisting multiple (i.e. two, three, four, or five) asymmetric attractors for some appropriately selected values of parameters. Laboratory experimental tests are conducted to support the theoretical analysis. The results obtained in this work clearly indicate that chaotic circuits with back to back diodes can demonstrate much more complex dynamics than what is reported in the relevant literature and thus should be reconsidered accordingly following the method described in this paper.

What's New About Fake News?

The term "fake news" ascended rapidly to prominence in 2016 and has become a fixture in academic and public discussions, as well as in political mud-slinging. In the flurry of discussion, the term has been applied so broadly as to threaten to render it meaningless. In an effort to rescue our ability to discuss—and combat—the underlying phenomenon that triggered the present use of the term, some philosophers have tried to characterize it more precisely. A common theme in this nascent philosophical discussion is that contemporary fake news is not a new kind of phenomenon, but just the latest iteration of a broader kind of phenomenon that has played out in different ways across the history of human information-dissemination technologies. While we agree with this, we argue that newer sorts of fake news reveal substantial flaws in earlier understandings of this notion. In particular, we argue that no deceptive intentions are necessary for fake news to arise; rather, fake news arises when stories which were not produced via standard journalistic practice are treated as though they had been. Importantly, this revisionary understanding of fake news allows us to accommodate and understand the way that fake news is plausibly generated and spread in a contemporary setting, as much by non-human actors as by ordinary human beings.

Phantom holomorphic projections arising from Sturm’s formula

We construct Siegel Poincare series of weight three and genus two outside their natural domain of convergency by the method of analytic continuation. In contrast to genus two Poincare series of higher weights greater three, the Poincare series thus obtained do not define holomorphic cuspforms of weight three. In fact, additional nonholomorphic phantom parts show up and we are able to describe them explicitly in terms of holomorphic forms of weight one. As a consequence of this result on Poincare series, in the case under consideration we can also show that Sturm’s operator not only projects to the holomorphic discrete series of weight three, as one would expect, but also gives rise to an additional phantom projection. For genus two the weight three case is distinguished, giving the first example for this new kind of phenomenon.

Color fluctuations in high energy hadron- and photon-nucleus collisions

We explain that coherence of high energy QED and QCD processes implies existence of new kind of phenomena which are beyond a framework based on Regge poles (cuts). New phenomena emerge as the consequence of compositeness of the bound states and the Lorentz slowing down of interaction. We focus on the color fluctuations phenomena predicted earlier for [Formula: see text] collisions within QCD and recent evidence for this phenomenon from [Formula: see text] LHC run, significant modification of nuclear shadowing phenomenon in the diffractive photoproduction of vector mesons observed recently in the ultra peripheral collisions at LHC. We outlined briefly general properties of color fluctuations phenomena and perspectives of future studies of this phenomenon in electron (photon) collisions with nuclei.

A theory of 2+1D bosonic topological orders

Abstract In primary school, we were told that there are four phases of matter: solid, liquid, gas, and plasma. In college, we learned that there are much more than four phases of matter, such as hundreds of crystal phases, liquid crystal phases, ferromagnet, anti-ferromagnet, superfluid, etc. Those phases of matter are so rich, it is amazing that they can be understood systematically by the symmetry breaking theory of Landau. However, there are even more interesting phases of matter that are beyond Landau symmetry breaking theory. In this paper, we review new ‘topological’ phenomena, such as topological degeneracy, that reveal the existence of those new zero-temperature phase—topologically ordered phases. Microscopically, topologically orders are originated from the patterns of long-range entanglement in the ground states. As a truly new type of order and a truly new kind of phenomena, topological order and long-range entanglement require a new language and a new mathematical framework, such as unitary fusion category and modular tensor category to describe them. In this paper, we will describe a simple mathematical framework based on measurable quantities of topological orders (S, T, c) proposed around 1989. The framework allows us to systematically describe all 2+1D bosonic topological orders (i.e. topological orders in local bosonic/spin/qubit systems).

Experimental Evidence of a Zonal Magnetic Field in a Toroidal Plasma

A zonal magnetic field is found in a toroidal plasma. The magnetic field has a symmetric bandlike structure, which is uniform in the toroidal and poloidal directions and varies radially with a finite wavelength of mesoscale, which is analogous to zonal flows. A time-dependent bicoherence analysis reveals that the magnetic field should be generated by the background plasma turbulence. The discovery is classified as a new kind of phenomenon of structured magnetic field generation, giving insight into phenomena such as dipole field generation in rotational planets.

Small Production and State Intervention in Agriculture

The rapid accumulation of state functions in agriculture during this century is a new kind of phenomenon in our history. It is also a process common to all developed capitalist countries in Europe. This article concentrates on the main features of agricultural policies in Finland, in order to illustrate the socio-economic reasons behind state intervention in agriculture. Production, income and structural policies all have, besides agricultural, also more general social and economic goals But mechanisms exist that counteract the attainment of these goals Capitalization of subsidies to land prices, differentiation as a cause and as a consequence of policies, and rising accumulation threshold are considered It is suggested that expanded repro duction is inevitable for family farms and that generation change is a most critical point of the reproduction process. Thus it also is a most strategic object for state intervention.

Low Thermal Expansion of Alkali Zirconium Phosphates Using a Microcomputer Automated Diffractometer

The thermal expansion of ceraptic materials has become a property of interest to more people recently since the desirability of a thermally stable space platform was recognized. The interest in low thermal expansion materials in the past has been driven mildly by the recognition that low thermal expansion will foster good thermal shock resistance. The tradition of the ceramics industry for nearly one hundred years has been that zircon and cordierite were the low expanding materials. Fused silica has long been recognized for its low expansion. But when in 1947 Hummel (1957, I960) found ultra-low-expanding bodies in the lithium aluminum silicates with spodumene and later β-eucryptite structures, a new kind of phenomena had been introduced. Roy (1949), Roy, Roy and Osborn (1950) and Roy and Osborn (1959) provided much of the crystal chemical and phase diagram background on this family.

The "Social Forces" Error

At the World's Congress of Arts and Sciences which was held at St. Louis in I904, I ventured to enter a protest against the loose way in which the word is employed by sociologists, saying among other things that sociologists have no more occasion to refer to any than the biologists have to speak of a vital There is a concept of force in general, to which I raise no objection, and there is a concept of social forces in particular, which is the object of my criticism. The former is the general metaphysical concept of power. In this sense according to prevalent modern philosophy there is but One Force which underlies and continuously causes all things that do appear, and is operative in the swinging of the spheres, in the bubbling of gases, and in the chemistry of growth in every grass blade. According to the theory of evolution the operation of The Force appeared first in the simplest phenomena, not however absolutely without differences among themselves. These simple phenomena became the conditions of other phenomena which, being added to the first, made a more complex situation and afforded the conditions for still other manifestations, or as we say, other phenomena, every new kind of phenomena being added to those which had preceded to form the conditions of still higher manifestations of the One Power. Scientific explanation is the description of the situation out of which a new kind of phenomena emerges a statement of those conditions which are the necessary logical antecedents of the phenomena explained. Now as often as we come across a kind of phenomena the conditioning of which we do not understand, we are tempted to say it is caused by a force. It is indeed caused by The Force
