Elektromagnetisch induzierte Transparenz mit einem einzelnen Atom

Diese Arbeit demonstriert erstmalig das Phanomen der elektromagnetisch induzierten Transparenz (EIT) mit einem einzelnen Atom. Ein koharenter atomarer Dunkelzustand wird dazu verwendet, die Transmission eines Laserstrahls optisch zu kontrollieren. Die dafur notwendige, verstarkte Wechselwirkung von Licht und Materie wird durch die Kopplung des Atoms an die Mode eines optischen Resonators erreicht. Neben der Skalierung des Transmissionsspektrums mit der Atomzahl wird auch die Verlangsamung eines Lichtpulses unter EIT-Bedingungen untersucht. In einem zweiten Experiment wird die effiziente Erzeugung von Atom-Photon-Verschrankung auf der D1-Linie von Rubidium gezeigt. Durch das Abspeichern des Einzelphotons in einem Bose-Einstein-Kondensat wird dieses mit dem einzelnen Atom verschrankt und damit ein elementares, hybrides Quantennetzwerk realisiert.
Modeling of Proton Exchange Membrane Fuel Cell Performance with an Empirical Equation

An empirical equation [E = E{sub 0} {minus} b log i {minus} Ri {minus} m exp (in)] was shown to fit the experimental cell potential (E) vs. current density (i) data for proton exchange membrane fuel cells (PEMFCs), at several temperatures, pressures, and oxygen compositions in the cathode gas mixture. The exponential term compensates for the mass-transport regions of the E vs. i plot; i.e., the increase in slope of the pseudolinear region and the subsequent rapid fall-off of the cell potential with increasing current density. As has been previously shown, the terms E{sub 0} and b yield the electrode kinetic parameters for oxygen reduction in the PEMFC and R represents the resistance, predominantly ohmic and, to a small extent, the charge-transfer resistance of the electro-oxidation of hydrogen. The exponential term characterizes the mass-transport region of the E vs. i plot. The parameter n has more pronounced effects than the parameter m in this region. A physicochemical interpretation of these parameters is needed. The PEMFC is the most promising candidate fuel cell power source for a zero emission vehicle, because of its desirable characteristics, such as quick start capability, low operating temperature, high energy efficiency, and high power density.
General Applicability of the Channels Ratio Method of Measuring Liquid Scintillation Counting Efficiencies.

Determination of the counting efficiencies of liquid scintillation samples as a function of the ratio of the count rates in two channels of the pulse height spectrum is examined for a much wider variety of quenching agents, solvent systems, and fluor concentrations than previously reported. The behavior of the curves of efficiency vs channels ratio is examined as a function of small changes in multiplier phototube and discriminator voltages and other instrumental variables, and the overall accuracy of the method is assessed. It is concluded that the method is much more widely applicable than is generally realized and that extremely useful results are obtainable when instrumental parameters are properly chosen. (auth)
Analysis of Factors Affecting Temperature Rise of Oil-immersed Power Transformer

The key factors that affect the operation state of power transformer include thermal problem and insulation problem. It is of great significance to pay attention to the factors affecting the temperature rise characteristics of transformer to ensure its stable operation. The temperature rise characteristic model of transformer is established to explore the possibility of replacing mineral oil with plant insulation oil FR3 in this paper. On the basis of calculating the influence of ambient temperature change of external heat source on transformer temperature rise, the relative life loss rate of transformer under different ambient temperature is calculated. The results show that FR3 vegetable oil can replace mineral oil in terms of temperature rise. The temperature of the transformer core and winding hot spot increases with the ambient temperature. When the ambient temperature exceeds 293K, the relative life loss rate of the transformer increases very quickly. Therefore, the transformer should not be kept in an environment where the temperature exceeds 293K for a long time.
Positive real lemmas for singular fractional‐order systems: the case

: This study investigates the positive real lemmas for singular fractional-order linear time-invariant systems with the fractional order α ∈ (0,1) . Firstly, a novel condition for the stability and extended strictly positive realness of fractional-order systems is derived in terms of linear matrix inequalities. Secondly, a novel condition for the admissibility and extended strictly positive realness of singular fractional-order systems is obtained with two complex variables. Then, another novel condition for the admissibility and extended strictly positive realness of singular fractional-order systems is established with only one complex variable. Thirdly, the positive real controller synthesis problems are analysed and the corresponding positive real controllers are designed based on the positive real lemmas. Finally, four numerical examples are provided to show the effectiveness of the proposed results in this study.
A vivência de práticas físicas/motoras/esportivas de homens e mulheres para propor o construto orientação esportiva

O objetivo deste trabalho teórico-empírico foi investigar o histórico de vida das práticas físicas/ motoras/ esportivas de 407 graduandos de Ed. Física de uma universidade pública (211 homens e 196 mulheres) para tentar averiguar um traço de orientação para a prática de diferentes modalidades esportivas. Esse estudo foi realizado a partir de dados empíricos sobre a experiência prévia dos seus participantes para identificar um possível traço latente comum aos sujeitos desta pesquisa em suas preferências esportivas. Na análise dos dados utilizou-se recursos da estatística descritiva e inferencial por meio de testes t de student, qui quadrado, análise de regressão linear (backward) e análise fatorial exploratória. Os resultados mostraram que homens quanto as mulheres gostam tanto de atividades físicas cíclicas como complexas. No entanto, os homens demonstraram gostar mais de atividades físicas complexas. A diferença em relação ao perfil motor/esportivo entre os sexos caracteriza-se pela preferência dos homens por esportes coletivos de embate, enquanto as mulheres, por atividades físicas coletivas ligadasao ritmo. Diante dos resultados observados foi possível identificar um traço predominante para homens e mulheres, embasando a proposta de um novo constructo sobre a orientação esportiva composto por duas dimensões, embatividade e ritmicidade. Este novo constructo exige a proposição de um instrumento de medida que possa medir e predizer a orientação esportiva nas Ciências do Movimento.
Data Augmentation Method for Switchgear Defect Samples Based on Wasserstein Generative Adversarial Network

The problem of sample imbalance will lead to poor generalization ability of the deep learning model algorithm, and the phenomenon of overfitting during network training, which limits the accuracy of intelligent fault diagnosis of switchgear equipment. In view of this, this paper proposes a data augmentation method for switchgear defect samples based on Wasserstein generative adversarial network with the partial discharge live detection data of the substation and the real-time switchgear partial discharge simulation experimental data. This method can improve the imbalanced distribution of data, and solve the problems such as the disappearance of gradients and model collapses in the classic generative adversarial network model, and greatly improve the stability of training. Verification through examples and comparison with traditional data augmentation methods. The results show that the data augmentation method mentioned in this paper can more effectively reduce the data imbalance, improve the performance of data-driven technology, and provide data support for subsequent fault diagnosis of switchgear equipment.
Peer-to-Peer Energy Trading in a Prosumer-Based Community Microgrid: A Game-Theoretic Model

This paper proposes a novel game-theoretic model for peer-to-peer (P2P) energy trading among the prosumers in a community. The buyers can adjust the energy consumption behavior based on the price and quantity of the energy offered by the sellers. There exist two separate competitions during the trading process: 1) price competition among the sellers; and 2) seller selection competition among the buyers. The price competition among the sellers is modeled as a noncooperative game. The evolutionary game theory is used to model the dynamics of the buyers for selecting sellers. Moreover, an M-leader and N-follower Stackelberg game approach is used to model the interaction between buyers and sellers. Two iterative algorithms are proposed for the implementation of the games such that an equilibrium state exists in each of the games. The proposed method is applied to a small community microgrid with photo-voltaic and energy storage systems. Simulation results show the convergence of the algorithms and the effectiveness of the proposed model to handle P2P energy trading. The results also show that P2P energy trading provides significant financial and technical benefits to the community, and it is emerging as an alternative to cost-intensive energy storage systems.
Alcances y limitaciones de Programas de Entrenamiento Cognitivo Computarizado Dirigidos al Trastorno por déficit de atención con hiperactividad

Background: In recent years, the use of computerized cognitive training programs (CCT) has increased as a non-invasive therapeutic alternative, based on the brain's ability to modify itself structurally and functionally. The programs are aimed at the healthy population and at patients who have a specific disorder, including Attention Deficit Hyperactivity Disorder (ADHD). However, its effectiveness and the possibility of transferring the results to everyday life is still a controversial issue. The objective of this study was to identify the achievement and limitations of ECC programs aimed at children with ADHD. Method: Articles published in scientific journals registered in the PROQUEST database were taken as reference, during the years 2008 to 2018, under the commands "cognitive training", "ADHD", "children and youth". Results: 1229 articles were located, in the manual search of the reference list, 6 studies were identified that fulfilled the inclusion requirements. ECC programs were evaluated through controlled empirical studies, aimed at children with ADHD. Conclusions: The review made it possible to identify that, in general, the ECC is useful for the treatment of ADHD in terms of attentional difficulties or working memory. The evidence is ambiguous in terms of its impact on everyday life
The effect of soil electrical conductivity on moisture determination using time-domain reflectometry in sandy soil

A series of laboratory experiments was conducted, in order to systematically explore the effect of soil electrical conductivity on soil moisture determination using time domain reflectometry (TDR). A Moisture Point MP-917 soil moisture instrument (E.S.I. Environmental Sensors Inc., Victoria, BC, Canada) was used to measure propagation time (time delay) of a step function along a probe imbedded in fine sand with different moisture and salinity. The volumetric soil water content was independently determined using a balance. With the help of the diode-switching technique, MP-917 could detect the reflection from the end of the probe as the electrical conductivity of saturated soil extract (ECe) increased to 15.29 dS m−1. However, the relationship between volumetric soil water content and propagation time expressed as T/Tair (the ratio of propagation time in soil to that in air over the same distance) deviated from a linear relationship as the conductivity exceeded 3.72 dS m−1. At the same water content, the t.
Is the RENP Process Probable for a Xe Atom Embedded in Quantum Solid

We studied the excitation spectra in the case of Xe@(p-H2)n embedded in a solid-state parahydrogen, making use of the ab initio molecular orbital method (QMO), in order to seek the possibility of the radiative emission of the neutrino pair (RENP) process that may be associated with the E1 × M1 transition processes. By means of a QMO calculation, the remarkable matrix effect was found in the structure of the electronic states. Three E1-type excitation bands (e1, e2, e3, in the order of increasing energy) in the UV absorption were found. In the present preliminary calculation, the second was too close to be clearly/well distinguished as an independent peak observed in the last experiment. Nevertheless, across the second (e2) band, two associated bands that may link to the M1-type transition were found. Therefore, the M1-type de-excitation process may be probable with the help of intensity borrowing from the e2 band, which may support the probability of the RENP process.
Substation Equipment Fault Identification Based on Infrared Image Analysis

As a key part of the power system, the substations undertake important work. With the development and construction of smart grids, the status data, image monitoring data, and environmental meteorological data of power systems are gradually being integrated and shared on a unified platform. Traditional models based on theoretical analysis are difficult to deal with multi-dimensional, massive data set information. Under this background, starting from the inherent law of the data itself, the use of machine learning methods combined with the infrared image data of the equipment can achieve intelligent identification and early warning of substation equipment failures. This paper first uses the convolutional neural network to identify the substation equipment in the picture, and then combines the infrared image to perform image registration. Finally, the deep belief network is used to determine whether the device is in wrong condition. The overall substation equipment fault identification is tested on real data, and the experimental results show that the proposed method has high accuracy.

Fever as an independent prognostic factor in traumatic brain injury

Traumatic Brain Injury (TBI) patients more often than not develop fever within the first few days of their hospitalization. Studies report that causes are variable and according to the pathogenesis, fever may be harmful or protective. The study was conducted to correlate the development of fever with clinical prognosis. Throughout the study spanning 6 months, a total of 98 patients of TBI were included. In the first 48 hours, 54 patients did not develop fever (temperature >37? ), 20 patients recorded temperatures between 37? and 39? ; and 24 patients developed high fever (39? ). On regular temperature monitoring and follow up, it was found that patients developing fever relatively early during hospitalization were more likely to end up with a poor outcome (Glasgow outcome scale 4 to 5). Therefore, fever is independently a predictor of poor prognosis in TBI patients and should be managed diligently in the first few days.
RESONANCE BEHAVIOR OF THE DIELECTRIC CONSTANT OF GaAs AT MICROWAVE FREQUENCIES

It has been observed that the lattice dielectric constant of single‐crystal gallium arsenide exhibits a broad resonance centered at about 9.5 GHz. The magnitude of the changes of dielectric constant associated with this resonance is comparatively large, but the magnitude of the losses associated with it is quite low. No satisfactory explanations for this resonance behavior has been suggested to date.
An Exploration of Richard Powers’ Ecological Thoughts in His The Echo Maker

Richard Powers is one of American famous contemporary writers, a rising star of American postmodernist fiction, and one of the representatives of the Generation Xers as well. He explores the impacts of some factors such as ecological environment, social culture, and family ethics on our modern society by use of his abundant knowledge about gene engineer, neurology, family ethics, etc. From the perspective of Marxism ecological philosophy, this paper deeply analyses The Echo Maker, Richard Powers’ masterpiece and interrelates the ecological thoughts implied in this novel. This work criticizes anthropocentrism and expresses the priority of nature. Human being is part of nature which our human being bases on and human being is closely related with nature. Human being should develop ecological consciousness, respect and care nature, and try every means to keep benign interaction with nature in order to build a stable and harmonious global community.
La rilevanza pratica dei sistemi di misurazione delle performance negli Enti Locali: analisi di un caso

The relevance of performance measurement systems in Local Authorities In the last decades, public organisations have been subject to several institutional changes, aimed at increasing their efficiency through the introduction of management control tools. The proliferation of management accounting tools planned for public companies has not always generated a corresponding diffusion of these tools in practice, widening the gap between theoretical models and practice. This gap is due to the divergence between meanings and roles assigned to performance measurement by theoretical models and practical dimensions. Focusing on the Local government context, this paper aims to understand the practical relevance of performance measurement systems in public organizations, verifying how these systems can affect the logics and behaviours of actors involved in the decision making pro-cess. The theoretical insights coming from literature review are used to interpret the practical relevance of performance measurement systems in a case study of a Local government placed in the South of Italy. The empirical evidence showed that the actors’ interests and objectives can affect the Performance Plan contents and its im-plementation, activating interpretive processes that are not always consistent with the underlying logics to which the measurement should be inspired. The case study showed how the practical relevance of the performance Plans is greater for those projects in which there was a sharing of the measurement meanings by political and administrative actors, which affects the definition of the Performance Plan contents and its implementation.
The Phonological of Patani Malay Dialect: An Analysis Of Autosegmental Theory

This paper aims at identifying and determining Malay dialect phonemes and the syllable structure of Patani Malay Dialect (PMD). The study is also conducted to analyze the phonological processes of PMD. The researcher used The autosegmental theory based on distinctive feature geometry model by Halle (1995), Clement’s representation level of syllable structure (1985) and, Zaharani and Teoh Boon Seongs’ building of syllable structure (2006). A qualitative method was used in this study. The data were collected from the field work where observations and interviewing were carried out. The results show that the PMD can be divided into three vowel phoneme categories. The first vowel phoneme category consists of six vowel phonemes. They are /i/, /e/, /a/, /«/, /o/, /u/. The second vowel phoneme category has two derived vowel phonemes such as [E], [] and the last vowel phoneme category consists of four nasalization vowels such as [u)], [E)], [)] dan [a)]. The study also found that PMD has 28 consonants. They can be grouped into three consonant categories. The first consonant category consists of 20 original consonants such as /p/, /t/, /k/, /b/, /d/, /g/, /c&/, /j&/, /s/, /l/, /r/, /A/, /m/, /n/, /N/, /o/, /w/, /j/, /h/, ///. The second consonant category has four aspiration consonants such as /p h /, /t h /, /k h /, /c h /. The third consonant category has four loan consonants such as /f/, /z/, /x/, /S/. While the syllable structure of PMD is categorised as type III which is a pattern of CV(C) syllable. The study suggests that the phonological processes of PMD identified and analysed based on the autosegmental theory have the characteristics of assimilation, vowels nasalizasion, deletion, glottalisation, monophthongisation and vowels changing.
Orientação sexual e seus efeitos no mercado de trabalho: um estudo com base na técnica de revisão sistemática

Ao fazer uso da técnica de revisão sistemática, este trabalho apresenta dois objetivos. Em primeiro lugar, procurou-se identificar por meio da literatura especializada diferentes formas de classificação da orientação sexual no âmbito do mercado de trabalho. Tendo em vista o segundo objetivo, analisou-se o mercado de trabalho como um canal que gera distribuição desigual de renda mediante mecanismos discriminatórios a partir dos diferenciais de rendimentos com base na orientação sexual. A fonte de dados utilizada foi a plataforma Periódicos Capes. Entre os resultados, quatro formas de identificação da orientação sexual foram observadas, tendo as uniões consensuais (coabitação) o maior número de estudos, seguidas da autodeclaração, comportamento e militância. Adicionalmente, pode-se destacar a penalidade salarial sofrida por homens gays vis-à-vis as suas contrapartes sexuais, prêmio salarial para lésbicas, com relação às mulheres heterossexuais, e desvantagens dos homossexuais na inserção do mercado de trabalho em simulações na taxa de convite para entrevista, revelando, assim, indícios de discriminação logo na etapa inicial de contratação. Finalmente, é ressaltado que, mesmo na presença de legislações que protejam minorias sexuais, até em países mais liberais e tolerantes, o ambiente profissional não está completamente alinhado à produtividade do trabalhador.
