It was recently conjectured that 1/f noise is a fundamental characteristic of spectral fluctuations in chaotic quantum systems. In this Letter we show that the level fluctuations of experimental realizations of the Sinai billiard exhibit {\em 1/f} noise, corroborating the conjecture. Assuming that the statistical properties of these systems are those of the Gaussian orthogonal ensemble (GOE), we compare the experimental results with the universal behavior predicted in the random matrix framework, and find an excellent agreement. The deviations from this behavior observed at low frequencies can be easily explained with the semiclassical periodic orbit theory. In conclusion, it is shown that the main features of the conjecture are affected neither by non-universal properties due to the underlying classical dynamics nor by the uncertainties of the experimental setup., Comment: 5 pages, 2 figures, submitted to Europhysics Letters

The power law $1/f^{\alpha}$ in the power spectrum characterizes the fluctuating observables of many complex natural systems. Considering the energy levels of a quantum system as a discrete time series where the energy plays the role of time, the level fluctuations can be characterized by the power spectrum. Using a family of quantum billiards, we analyze the order to chaos transition in terms of this power spectrum. A power law $1/f^{\alpha}$ is found at all the transition stages, and it is shown that the exponent $\alpha$ is related to the chaotic component of the classical phase space of the quantum system., Comment: 4 pages, 5 figures, accepted for publication in Phys.

Nonlinear Sciences - Chaotic Dynamics - Abstract
It was recently conjectured that 1/f noise is a fundamental characteristic of spectral fluctuations in chaotic quantum systems. This conjecture is based on the behavior of the power spectrum of the excitation energy fluctuations, which is different for chaotic and integrable systems. Using random matrix theory we derive theoretical expressions that explain the power spectrum behavior at all frequencies. These expressions reproduce to a good approximation the power laws of type 1/f (1/f^2) characteristics of chaotic (integrable) systems, observed in almost the whole frequency domain. Although we use random matrix theory to derive these results, they are also valid for semiclassical systems., Comment: 5 pages (Latex), 3 figures

- Abstract
© 2006 The American Physical Society. We are particularly indebted to P. A. Mello for enlightening discussions. We also thank K. Wood for his help with this manuscript. This work is supported in part by Spanish Government Grants No. BFM2003-04147 and No. FTN2003-08337-C04-04., It is widely accepted that the statistical properties of energy level spectra provide an essential characterization of quantum chaos. Indeed, the spectral fluctuations of many different systems like quantum billiards, atoms, or atomic nuclei have been studied. However, noninteracting many-body systems have received little attention, since it is assumed that they must exhibit Poisson-like fluctuations. Apart from a heuristic argument of Bloch, there are neither systematic numerical calculations nor a rigorous derivation of this fact. Here we present a rigorous study of the spectral fluctuations of noninteracting identical particles moving freely in a mean field emphasizing the evolution with the number of particles N as well as with the energy. Our results are conclusive. For N >= 2 the spectra of these systems exhibit Poisson fluctuations provided that we consider sufficiently high excitation energies. Nevertheless, when the mean field is chaotic there exists a critical energy scale L-c; beyond this scale, the fluctuations deviate from the Poisson statistics as a reminiscence of the statistical properties of the mean field., Spanish Government, Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

- Abstract
©2006 The American Physical Society. This work is supported in part by Spanish Government Grants No. BFM2003-04147 and No. FTN2003-08337-C04-04., It was recently pointed out that the spectral fluctuations of quantum systems are formally analogous to discrete time series, and therefore their structure can be characterized by the power spectrum of the signal. Moreover, it is found that the power spectrum of chaotic spectra displays a 1/f behavior, while that of regular systems follows a 1/f(2) law. This analogy provides a link between the concepts of spectral rigidity and antipersistence. Trying to get a deeper understanding of this relationship, we have studied the correlation structure of spectra with high spectral rigidity. Using an appropriate family of random Hamiltonians, we increase the spectral rigidity up to hindering completely the spectral fluctuations. Analyzing the long range correlation structure a neat power law 1/f has been found for all the spectra, along the whole process. Therefore, 1/f noise is the characteristic fingerprint of a transition that, preserving the scale-free correlation structure, hinders completely the fluctuations of the spectrum., Spanish Government, Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

This work is supported in part by Spanish Government grants for the research projects BFM2003-04147-C02 and FTN2003-08337-C04-04., We apply a principal components analysis (PCA) to the secondary particle density distributions at ground level produced by cosmic gamma-rays and protons. For this purpose, high-energy interactions of cosmic rays with Earth's atmosphere and the resulting extensive air showers have been simulated by means of the CORSIKA Monte Carlo code. We show that a PCA of the two-dimensional particle density fluctuations provides a decreasing sequence of covariance matrix eigenvalues that have typical features of a polynomial law, which are different for different primary cosmic rays. This property is applied to the separation of electromagnetic showers from proton simulated extensive air showers, and it is proposed as a new discrimination method that can be used experimentally for gamma-proton separation. A cutting parameter related to the polynomial behavior of the decreasing sequence of covariance matrix eigenvalues is calculated, and the efficiency of the cutting procedure for gamma-proton separation is evaluated., Spanish Government, Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

- Abstract
©2002 The American Physical Society. This work is supported in part by Spanish Government Grants No. BFM2000-0600 and No. FTN2000-0963-C02., The main signature of chaos in a quantum system is provided by spectral statistical analysis of the nearest-neighbor spacing distribution P(s) and the spectral rigidity given by the Delta(3)(L) statistic. It is shown that some standard unfolding procedures, such as local unfolding and Gaussian broadening, lead to a spurious saturation of Delta(3)(L) that spoils the relationship of this statistic with the regular or chaotic motion of the system. This effect can also be misinterpreted as Berry's saturation., Spanish Government, Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

- Abstract
International Spring Seminar on Nuclear Physics: New Quests in Nuclear Structure (10th. 2010. Vietri sul Mare, Italy), A survey of chaotic dynamics in atomic nuclei is presented, using on the one hand standard statistics of quantum chaos studies, and on the other a new approach based on time series analysis methods. The study of shell-model spectra in the pf shell shows that nuclear chaos is strongly isopin dependent and increases with excitation energy. On the other hand, it is found that chaotic quantum systems exhibit 1/f noise and regular systems exhibit 1/f(2) behaviour. It is shown that the time series approach can be used to calculate quite accurately the fraction of missing levels and the existence of mixed symmetries in experimental level spectra., Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

- Abstract
© 2015 IOP Publishing Ltd. International Spring seminar on nuclear physics: shell model and nuclear structure (11th. MAY 12-16, 2014. Ischia, Italia)., Shell-model calculations with realistic empirical interactions constitute an excellent tool to study statistical properties of nuclei. Using large-scale shell-model calculations in pf-shell nuclei, we study how the onset of chaos depends on different properties of the nuclear interaction and on excitation energy. We make use of classical random matrix theory and other theoretical developments based on information theory and time series analysis. We show that besides energy-level statistics, other statistical properties like the complexity of wave functions are fundamental for a proper determination of the dynamical regime of nuclei. Important deviations from GOE are observed in level fluctuations and in the complexity of wave functions., Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

© 2008 The American Physical Society. This work was supported in part by Spanish Government Grants Nos. FIS2006-12783-C03-01 and FIS2006-12783-C03-02 and by Comunidad de Madrid–CSIC Grant No. 200650M012. A.R. was supported by the Spanish program “Juan de la Cierva”., The continuous Gaussian ensemble, also known as the nu-Gaussian or nu-Hermite ensemble, is a natural extension of the classical Gaussian ensembles of real (nu= 1), complex (nu= 2), or quaternion (nu=4) matrices, where nu is allowed to take any positive value. From a physical point of view, this ensemble may be useful to describe transitions between different symmetries or to describe the terrace-width distributions of vicinal surfaces. Moreover, its simple form allows one to speed up and increase the efficiency of numerical simulations dealing with large matrix dimensions. We analyze the long-range spectral correlations of this ensemble by means of the delta(n) statistic. We derive an analytical expression for the average power spectrum of this statistic, <(P(k)(delta))over bar>, based on approximated forms for the two-point cluster function and the spectral form factor. We find that the power spectrum of delta(n) evolves from <(P(k)(delta))over bar> proportional to 1/ k at nu= 1 to <(P(k)(delta))over bar> proportional to 1/ k(2) at nu= 0. Relevantly, the transition is not homogeneous with a 1/ f alpha noise at all scales, but heterogeneous with coexisting 1/ f and 1/ f(2) noises. There exists a critical frequency k(c)proportional to nu that separates both behaviors: below k(c), <(P(k)(delta))over bar> follows a 1/f power law, while beyond kc, it transits abruptly to a 1/ f(2) power law. For nu>1 the 1/ f noise dominates through the whole frequency range, unveiling that the 1/ f correlation structure remains constant as we increase the level repulsion and reduce to zero the amplitude of the spectral fluctuations. All these results are confirmed by stringent numerical calculations involving matrices with dimensions up to 10(5)., Spanish Government, Comunidad de Madrid, CSIC, Spanish program “Juan de la Cierva”, Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

© 2006 Elsevier B.V. All rights reserved. R.A.M. would like to thank E. Grosse, A.Wagner and G. Rusev of the Fz. Rossendorf for suggesting this work. A.R. is supported by the Spanish “Juan de la Cierva” program. This work is supported in part by Spanish Government grants BFM2003-04147-C02 and FTN2003-08337-C04-04., Sequences of energy levels in nuclei are often plagued with missing levels whose number and position are unknown. It is also quite usual that all the quantum numbers of certain levels cannot be experimentally determined, and thus levels of different symmetries are mixed in the same sequence. The analysis of these imperfect spectra (from the point of view of spectral statistics) is unavoidable if one wants to extract some statistical information. The power spectrum of the delta(q) statistic has emerged in recent years as an important tool for the study of quantum chaos and spectral statistics. We derive analytical expressions for the observed power spectrum in terms of the fraction of observed levels and the number of mixed sequences. These expressions are tested with large shell model spectra simulating realistic experimental situations. A good estimation of the number of mixed symmetries and the fraction of missing levels is obtained by means of a least-squares fit in a wide set of different situations., Spanish “Juan de la Cierva” program, Spanish Government, Depto. de Estructura de la Materia, Física Térmica y Electrónica, Fac. de Ciencias Físicas, TRUE, pub

El repentino cambio climático y los desastres ambientales, naturales o provocados por el hombre, han obligado a miles de personas en todo el mundo a abandonar sus países en busca de refugio y de una vida mínimamente digna en otro territorio. Este artículo busca abordar el problema del desplazamiento humano causado por estas catástrofes, investigando la protección legal requerida para estas personas desplazadas a la luz de un análisis del Estatuto de Refugiado desde la perspectiva del principio pro homine. Para ello, además de una explicación sobre el refugiado, como instituto jurídico de protección a nivel mundial, se analizarán los desastres ambientales para discutir, posteriormente, uno de los problemas que surgen, precisamente, por estos desastres, que no es otro que el desplazamiento masivo de personas, forzadas por la falta de condiciones para permanecer en la zona afectada con dignidad.

Capim Annoni ,Eragrostis Plana ,Erva Daninha - Abstract
The current study evaluated the efficiency of mechanical, physical, chemical and cultural methods, used exclusively or integrated, to control tough lovegrass. The experimental design was completely randomized, with 15 treatments and four repetitions. Physical control of tough lovegrass was based on the application of fire, whereas mechanical controls consisted in mowing and harrowing/plowing procedures. The herbicide clethodim and different glyphosate salts were evaluated for chemical control. Glyphosate and soil fertility correction were applied as cultural and integrated methods, in addition to isopropylamine + potassium salts combination, soil fertility correction and implantation of one of the following forage plants: Elephant grass, Pangola grass, Forage peanut and Birdsfoot trefoil. The effect of treatments on the incidence of tough lovegrass and on its botanical composition was evaluated one year after their applications. Isolated control methods, except for glyphosate using, did not present efficient tough lovegrass control. Glyphosate salts could control tough lovegrass plants, but their association with improved soil fertility and Pangola grass implantation was the best strategy to control the invasive plant. Key words: Eragrostis plana Nees, native pasture, weed control. Made available in DSpace on 2022-04-06T14:06:37Z (GMT).

The objective of the study was to evaluate the efficiency of herbicides use in the control of tough lovegrass according to the availability of solar radiation and the presence or absence of flooded. Two experiments were conducted in a completely randomized design, in a 2x2x4 and 2x2x5 factorial scheme, where factor A was equivalent to the environment (natural or reduced radiation); factor B to water condition (with a 2 cm flooded or without); and, factor C the herbicides: cyhalofop butyl (315 g ha-1), glyphosate (1080 g ha-1), cyhalofop butyl + glyphosate (315 g ha-1 + 1080 g ha-1) and control (without application) in the first experiment. In the second experiment, the herbicides used were cyhalofop butyl (315 g ha-1), glyphosate (1080 g ha-1), sethoxydim (184g ha-1), imazethapyr (106 g ha-1) and control (without application). Glyphosate efficiently controls plants of tough lovegrass with four tillers (>90%), being superior to cyhalofop, imazethapyr and sethoxydim; independently, of resource conditions. Reduction in the availability of solar radiation generates less shoot dry mass production from the weed, and improves the control only by imazethapyr and cyhalofop. In general, a flooded condition does not affect tough lovegrass control by herbicides.Key words: flooded, glyphosate, pasture, shading, weed control.

Para isso, foram conduzidos dois experimentos em delineamento inteiramente casualizado, em esquema fatorial 2x2x4 e 2x2x5, em que o fator A equivaleu ao ambiente (radiação natural ou reduzida); fator B à condição hídrica (com lâmina d?água de 2 cm ou sem); e, o fator C aos herbicidas: cyhalofop butyl (315 g ha-1), glyphosate (1080 g ha-1), cyhalofop butyl + glyphosate (315 g ha-1 + 1080 g ha-1) e testemunha (sem aplicação) no primeiro experimento. No segundo experimento, os herbicidas utilizados foram: cyhalofop butyl (315 g ha-1), glyphosate (1080 g ha-1), sethoxydim (184 g ha-1), imazethapyr (106 g ha-1) e testemunha (sem aplicação). Glyphosate controla eficientemente plantas de capim-annoni com quatro afilhos (>90%), sendo superior a cyhalofop butyl, imazethapyr e sethoxydim, independente das condições. A redução da disponibilidade de radiação solar gera menor produção de matéria seca da parte aérea pelo capim-annoni, podendo inclusive, contribuir para maior eficiência de controle somente por imazethapyr e cyhalofop. De maneira geral, a condição de lâmina d?água não afeta o controle de capim-annoni pelos herbicidas.Palavras-chave: lâmina d ́água, glifosato, pastagem, sombreamento, controle de plan Made available in DSpace on 2021-02-03T15:19:21Z (GMT).

- Abstract
A epistasia já é conhecida desde o início dos estudos em genética, porém sua contribuição para as estimativas dos componentes da variância genética e para o melhoramento genético ainda não é bem entendida. A maioria dos modelos usados para estudar a herança dos caracteres quantitativos considera apenas os efeitos genéticos aditivos e de dominância, assumindo ausência da epistasia, mesmo que as análises não forneçam testes para tal suposição. Portanto, na sua presença, estimativas de variância aditiva e dominância, coeficientes de herdabilidade e respostas esperadas com a seleção estão viesadas. Os objetivos deste estudo foram: (i) verificar se a epistasia está presente na expressão de diversos caracteres em testecrosses; (ii) estimar os efeitos epistáticos em cada planta 2 F para estes caracteres; e (iii) verificar se a epistasia interage com ambientes e testadores. Uma população de 100 progênies F2:3 foi obtida do cruzamento das linhagens endogâmicas L-08-05F e L-38-05D e foram retrocruzadas com as linhagens parentais e sua geração 1 F , conforme o delineamento triple test cross. As 300 progênies de retrocruzamento foram cruzadas com as linhagens testadoras L-02-03D e L-04-05F. Os testecrosses obtidos foram avaliados em dez ambientes no município de Piracicaba, SP, em delineamento látice a no esquema fatorial com duas repetições por ambientes. Os caracteres avaliados foram produção de grãos, prolificidade, acamamento e quebramento de plantas, florescimento masculino e feminino, intervalo entre florescimentos, altura de planta e espiga e posição relativa da espiga. A presença de epistasia foi detectada para todos os caracteres nos testecrosses de ambos testadores, exceto para acamamento e quebramento de plantas em que a epistasia foi observada somente nos testecrosses provenientes do testador L-04-05F. Cada testador detectou efeitos epistáticos em diferentes grupos de plantas 2 F e estes não foram unidirecionais para todos os caracteres avaliados. A interação epistasia por testador foi significativa para todos os caracteres, enquanto que a interação epistasia x ambientes não foi observada para nenhum caráter em ambos testadores. A presença de desequilíbrio de ligação na população foi observada para todos os caracteres, exceto para acamamento e quebramento. As estimativas dos componentes de variância e dos coeficientes de herdabilidade diferiram significativamente de zero, com exceção dos parâmetros estimados para os testecrosses do testador L-04-05F para o caráter acamamento e quebramento. Os resultados sugerem que as estimativas da variância aditiva e dos coeficientes de herdabilidade para aqueles caracteres nos quais foi verificada a presença de epistasia estarão viesados, caso a epistasia seja desconsiderada. Além disso, a presença de desequilíbrio de ligação na população gera vieses adicionais nas estimativas desses parâmetros. Epistasis has been known since the beginning of the genetics studies. However its contribution to genetic variance components and to plant breeding is not well understood. Most of the genetic models designed to study the inheritance of the quantitative traits consider the absence of epistasis although most of these analyses dont provide test for such assumption. Therefore in its presence estimates of additive and dominance variances, heritability coefficients and selection responses would be biased. The objectives of this study were: (i) to verify whether epistasis is significant to the expression of several traits in testcrosses; (ii) to estimate the epistatic effects in individual 2 F plants for these traits; and (iii) to verify whether epistasis interacts with environment and with testers. A population of 100 3 : 2 F progenies from the cross of inbred lines L-08-05F and L-38-05D were backcrossed to the parental lines and their 1 F following the triple test cross design. The 300 backcrossed progenies were testcrossed to the inbred lines L-02-03D and L-04-05F. The 600 testcrosses were grown at ten environments in Piracicaba, SP, using the látice a design on a factorial scheme with two replications per environment. The traits recorded were grain yield, prolificacy, root and stalk lodging, days to anthesis, days to silk emergence, anthesis-silking interval, plant height, ear height and ear placement. Epistasis was detected for all traits in both testcrosses, but for root and stalk lodging epistasis was detected only in the testcrosses from L-04-05F tester. Each tester detected epistasis in different groups of 2 F plants, and the epistatic effects were not unidirectional for all traits. The epistasis by tester interaction was significant for all traits in both testers, but epistasis by environment interaction was not significant for all traits. Also linkage disequilibrium in the population was detected for all traits, except for root and stalk lodging. Estimates of variance components and heritability coefficients were all significant, except for testcrosses from L-04-05F tester for root and stalk lodging. The results suggested that the estimates of additive variance and heritability coefficients will be biased if the epistasis be unconsidered. Moreover the presences of linkage disequilibrium produce additional biases in the estimative theses parameters.

The objective of the research was to select common bean lines with pink grain, high grain yield with good cooking ability, and resistance to anthracnose and angular leaf spot. One hundred and forty three lines were selected from five F8 segregant families derived from the cross Rosinha Maria da Fé x ESAL 693. Those lines were evaluated in the rainy season of 2005/2006 at Lavras county, MG State. Ninety nine lines were kept and tested in the dry season of 2006 at Lavras and Lambari. The 24 selected lines were again evaluated in the same last sites in the winter/spring of 2006. Traits recorded included grain yield, grain type, cooking time, angular leaf spot reaction, and resistance test against the pathotype 65 of Colletotrichum lindemuthianum. The lines were genetically different for all traits as confirmed by the high estimates of heritability, assuring high selection gains. Four lines were selected with high grain yield and ideal pink type plus good cooking ability and resistance to anthracnose and angular leaf spot.

This study compared severity of angular leaf spot in common bean lines, based on the healthy and diseased leaf area, and the graded scale. We used 12 common bean lines in the dry and rainy seasons. Two contiguous experiments were conducted in each season, with and without chemical control of the pathogen. We evaluated the percentage of the healthy and diseased leaf area; severity based on a graded scale and the area under the disease progress curve; and yield. The diseased or healthy leaf area is efficient to evaluate the severity of angular leaf spot with a sample of 20 to 30 leaflets per plot. For all traits, the results of central and border areas did not differ, indicating that the evaluation of border rows is unnecessary and, finally, the severity assessment of the upper plant half can discriminate the lines more efficiently. A severidade da mancha angular do feijoeiro foi avaliada com base nas áreas sadia e doente da folha e na escala diagramática. Foram avaliadas 12 linhagens de feijão nas épocas das secas e das águas. Em cada época foram conduzidos dois experimentos contíguos, com e sem controle químico do patógeno. Foram avaliadas as porcentagens das áreas sadia e doente da folha, severidade da doença segundo uma escala diagramática, área abaixo da curva sob progresso da doença e produtividade de grãos. As áreas sadia e doente da folha são eficientes para avaliar a severidade da mancha angular com uma amostra de 20 a 30 folíolos por parcela. A avaliação de todos os caracteres na área útil ou bordadura da parcela não difere, indicando que a bordadura por parcela é desnecessária. A avaliação da severidade na metade superior da planta discrimina as linhagens mais eficientemente.

- Abstract
Shell-model calculations with realistic empirical interactions constitute an excellent tool to study statistical properties of nuclei. Using large-scale shell-model calculations in pf- shell nuclei, we study how the onset of chaos depends on different properties of the nuclear interaction and on excitation energy. We make use of classical random matrix theory and other theoretical developments based on information theory and time series analysis. We show that besides energy-level statistics, other statistical properties like the complexity of wave functions are fundamental for a proper determination of the dynamical regime of nuclei. Important deviations from GOE are observed in level fluctuations and in the complexity of wave functions.

Termodinámica - Abstract
The power spectrum of the δ_(n) statistic of quantum spectra presents 1/ƒ^(α) noise. For chaotic systems α = 1 while for regular systems α = 2. Although the transition from regularity to chaos is non universal, for a wide variety of systems with a mixed phase space the value of α is intermediate between 1 and 2 and can be related to the fraction of regular or chaotic orbits in the total phase space. This statistic can be a very useful tool for the analysis of experimental spectra, specially in the case of missing levels or spectral sequences with mixed symmetries.

The power law $1/f^{\alpha}$ in the power spectrum characterizes the fluctuating observables of many complex natural systems. Considering the energy levels of a quantum system as a discrete time series where the energy plays the role of time, the level fluctuations can be characterized by the power spectrum. Using a family of quantum billiards, we analyze the order to chaos transition in terms of this power spectrum. A power law $1/f^{\alpha}$ is found at all the transition stages, and it is shown that the exponent $\alpha$ is related to the chaotic component of the classical phase space of the quantum system., Comment: 4 pages, 5 figures, accepted for publication in Phys.

- Abstract
A survey of chaotic dynamics in atomic nuclei is presented, using on the one hand standard statistics of quantum chaos studies, and on the other a new approach based on time series analysis methods. The study of shell-model spectra in the pf shell shows that nuclear chaos is strongly isopin dependent and increases with excitation energy. On the other hand, it is found that chaotic quantum systems exhibit 1/f noise and regular systems exhibit 1/f 2 behaviour. It is shown that the time series approach can be used to calculate quite accurately the fraction of missing levels and the existence of mixed symmetries in experimental level spectra.
