Health direction of section on table tennis

The article is devoted to the formation of a versatile harmoniously physically developed personality, ready for active creative self-realization in the space of universal human culture. The article discusses the health-improving orientation of table tennis lessons among students. Table tennis is one of the means of physical development, increasing the role of physical culture in the upbringing of student youth, health promotion, increasing in the volume of physical activity of students, developing their physical qualities and improving physical fitness, instilling skills in a healthy lifestyle Training efficiency depends on the degree of rational organization of closeness of employments, optimal dosage of loading, account of individual features of stu-dents. Depending on these factors and stage of preparation, employments can be conducted by means of different organizational forms (group, individual, frontal forms of training). The work of the table tennis section contributes to the development of basic physical qualities, the formation of vital motor skills and abilities, the development of coordination abilities and special psychophysical qualities, such as reaction, attention, thinking. The game contributes to the upbringing of a harmoniously developed personality, aimed at long-term preservation of a high level of general performance, upbringing of positive personality traits, collective interaction and cooperation in educational and competitive activities. The main advantage of table tennis is that it is a game. The game can be viewed as a kind of model of the elements of real life, reproducing the practical behavior of a person within the boundaries of predetermined conditions.

Neoclassical Supply and Demand, Experiments, and the Classical Theory of Price Formation

Neoclassical price theory was founded on axioms of price-taking behavior and the law of one price in a market, axioms inconsistent with a theory of endogenous price discovery in markets. Classical economists including Adam Smith narrated a price discovery process based on buyer and seller reservation values and their motivation to buy low and sell high; the classical sketch of price formation offers a quite fruitful foundation for a modern theory of price discovery, supplied below. Market experiments, based on private distributed reservation values and using rules governing open-outcry double auctions, converged endogenously, in three to four periods of repeat interaction, to an efficient outcome. These observations contradicted the widely believed, thought, and taught necessity for perfect information, large numbers, and price-taking behavior. However, these results were consistent with the old, classical, conception of price formation emerging from the collective interaction of the traders. Aggregation and price discovery constitute essential functions of classical markets. We explore the divergence of neoclassical scholars from this classical tradition. Revealingly, in describing the microdynamics of market price formation, prominent neoclassical utilitarians such as Marshall, with his description of a “corn-market in a county town,” and Böhm-Bawerk with his farmers’ horse market, reverted to this classical reservation-value framework.

Hybrid big bang–big crunch with ant colony optimization for email spam detection

Electronic mails (emails) have been widely adapted by organizations and individuals as efficient communication means. Despite the pervasiveness of alternate means like social networks, mobile SMS, electronic messages, etc. email users are continuously growing. The higher user growth attracts more spammers who send unsolicited emails to anonymous users. These spam emails may contain malware, misleading information, phishing links, etc. that can imperil the privacy of benign users. The paper proposes a self-adaptive hybrid algorithm of big bang–big crunch (BB–BC) with ant colony optimization (ACO) for email spam detection. The BB–BC algorithm is based on the physics-inspired evolution theory of the universe, and the collective interaction behavior of ants is the inspiration for the ACO algorithm. Here, the ant miner plus (AMP) variant of the ACO algorithm is adapted, a data mining variant efficient for the classification. The proposed hybrid algorithm (HB3C-AMP) adapts the attributes of B3C (BB–BC) for local exploitation and AMP for global exploration. It evaluates the center of mass along with the consideration of pheromone value evaluated by the best ants to detect email spam efficiently. The experiments for the proposed HB3C-AMP algorithm are conducted with the Ling Spam and CSDMC2010 datasets. Different experiments are conducted to determine the significance of the pre-processing modules, iterations, and population size on the proposed algorithm. The results are also evaluated for the AM (ant miner), AM2 (ant miner2), AM3 (ant miner3), and AMP algorithms. The performance comparison demonstrates that the proposed HB3C-AMP algorithm is superior to the other techniques.

Generation and collective interaction of giant magnetic dipoles in laser cluster plasma

Interaction of circularly polarized laser pulses with spherical nano-droplets generates nanometer-size magnets with lifetime on the order of hundreds of femtoseconds. Such magnetic dipoles are close enough in a cluster target and magnetic interaction takes place. We investigate such system of several magnetic dipoles and describe their rotation in the framework of Lagrangian formalism. The semi-analytical results are compared to particle-in-cell simulations, which confirm the theoretically obtained terrahertz frequency of the dipole oscillation.

Intermittent decoherence blockade in a chiral ring environment

It has long been recognized that emission of radiation from atoms is not an intrinsic property of individual atoms themselves, but it is largely affected by the characteristics of the photonic environment and by the collective interaction among the atoms. A general belief is that preventing full decay and/or decoherence requires the existence of dark states, i.e., dressed light-atom states that do not decay despite the dissipative environment. Here, we show that, contrary to such a common wisdom, decoherence suppression can be intermittently achieved on a limited time scale, without the need for any dark state, when the atom is coupled to a chiral ring environment, leading to a highly non-exponential staircase decay. This effect, that we refer to as intermittent decoherence blockade, arises from periodic destructive interference between light emitted in the present and light emitted in the past, i.e., from delayed coherent quantum feedback.

Art and the Aesthetics of Cultural Gentrification : The Cases of Boyle Heights and Little Tokyo in Los Angeles

The art world has been linked to gentrification. Such art is associated with a modernist aesthetics based on abstraction, individual experience, and exchange value. This chapter identifies a different kind of art based on an aesthetics of engagement in the historic immigrant neighbourhoods of Boyle Heights and Little Tokyo in Los Angeles. This aesthetics is linked to ethics, collective interaction, and the participatory community development of specific places. Furthermore, gentrification is often only understood as an economic process. The concept of cultural gentrification is presented to demonstrate how transformations in the symbolic sphere can trigger a loss of belonging. Art that is borne from the specific culture of a place, however, can open up new potential in combating gentrification.

Complex networks approach for detecting tropical basin interactions

<p>Interaction between the tropical Pacific, Atlantic, and Indian Ocean basins is increasingly recognized as a key factor in understanding climate variability on interannual to decadal timescales. Most of the studies deal with the connection between pair of basins and less attention has been paid to analyze the degree of collective interaction among the three tropical oceans and its variability along time.In this study, we consider a complex network perspective to analyze the collective connectivity among the three tropical basins. To do so, we first construct a climate network considering as network’ nodes the indices that represent the variability of the SST over the tropical Pacific, the tropical north Atlantic, the equatorial Atlantic and the tropical Indian Ocean. Then, we focus on detecting periods of maximum degree of collective connectivity (synchronization periods) using the mean network distance definition.Results show that the degree of collective connectivity among the three tropical oceans present a large muti-decadal variability and that during the observed period there were two synchronization periods: one developed over the period (1900-1935) and the other from 1975 to present. A period center in the 1950’s is characterized by being the three basins uncoupled .Using this information, an analysis of background conditions in the ocean and the atmosphere has been conducted in order to elucidate causes for this change in connectivity.</p>

Cavity-enhanced microwave readout of a solid-state spin sensor

Overcoming poor readout is an increasingly urgent challenge for devices based on solid-state spin defects, particularly given their rapid adoption in quantum sensing, quantum information, and tests of fundamental physics. However, in spite of experimental progress in specific systems, solid-state spin sensors still lack a universal, high-fidelity readout technique. Here we demonstrate high-fidelity, room-temperature readout of an ensemble of nitrogen-vacancy centers via strong coupling to a dielectric microwave cavity, building on similar techniques commonly applied in cryogenic circuit cavity quantum electrodynamics. This strong collective interaction allows the spin ensemble’s microwave transition to be probed directly, thereby overcoming the optical photon shot noise limitations of conventional fluorescence readout. Applying this technique to magnetometry, we show magnetic sensitivity approaching the Johnson–Nyquist noise limit of the system. Our results pave a clear path to achieve unity readout fidelity of solid-state spin sensors through increased ensemble size, reduced spin-resonance linewidth, or improved cavity quality factor.

Universal Transcendental Logic-Based Ontology

In this paper, Kant's philosophical doctrine of the categories of the reason is used to substantiate the conceptual model of knowledge representation, based on the collective interaction of a lot of intellectual atomic elements of knowledge (knowledge quanta), which are combined into clusters like neurons in the brain; and also a phenomenological description of the corresponding universal ontology, proceeding from the philosophical premise of Husserl-Heidegger that the meaning of intelligence is not so much in knowing the absolute truth as in survival, is presented. In the process of cognizing the surrounding world, a person uses both a priori knowledge and a posteriori knowledge, but the transcendental content of a priori forms of thinking does not allow them to be used directly in logical judgments. Nevertheless, one can try to use them as "ontological predicates" following the advice of I. Kant, what was done in this article. Heuristic ontological relations that directly follow from the categories of Kant are easy to use and sufficient to describe any ontology. Offered knowledge representation model, the key idea of which is the primacy of knowledge to logical inference and their emergent ability to self-organize, in conjunction with the transcendental logic-based ontology of empirical knowledge can be used to create a universal inference engine.
