  1. Croatian "Judiths"

    Directory of Open Access Journals (Sweden)

    Teodora Vigato

    2016-02-01

    Full Text Available In this paper, the authors deal with various interpretations in Croatian literature of the biblical Judith and Marulić’s Judith. They begin with the story of Judith from Zadar whose anonymous authors had the task to spread the biblical story of the courageous Judith. Then they speak about Judith in the works of Antun Gleđević and Ignjat Đurđević, in the Baroque literature of Dubrovnik, in the context of the Dubrovnik melodramatic or pseudolibretistic production. The paper highlights the Slavonian Judith, that is, her interludes and concludes with the contemporary Judiths of Miro Gavran and Boris Senker. The biblical text has served also as an inspiration for various interpretations in a wide range of performances, from musical to puppet theatre. Each author followed the point of view, the artistically specific, poetic, structural and technical requirements of the genre and placed the main character and her story in a new intertextual or media content.

  4. The Rhetoric of Madness in Kathy Acker’s Don Quixote

    Directory of Open Access Journals (Sweden)

    Claudia Cao

    2017-07-01

    Full Text Available This essay examines the rhetorical experimentation of Don Quixote by Kathy Acker, starting from a theoretical concept central in the author’s thought: her search for a “language of the body”. A brief introduction to Kathy Acker’s plagiaristic poetics frames her narrative strategies between postmodern rewriting and pastiche. It shows the way in which her Don Quixote transposes the representative scheme of the chivalric quest into the contemporary value system with the aim of questioning Cervantes’ text as one of the canonical works of the Western literary tradition. The following section deepens three focal concepts of Acker’s theoretical works – body, madness, and norm – illuminating the connections between her rhetorical experimentation and the works by Luce Irigaray and Judith Butler. Finally, the paper will demonstrate how these concepts in Acker's rewriting of Don Quixote are strictly related to paradox, which she uses in order to actualize a “language of the body”: in the passage from the former novel to the postmodern work, madness has become the device which, from the semantic level to the rhetorical one, expresses Acker’s idea of language of the body, as an alternative and in contrast to the canonical language of the logos.

    Full Text Available

    After a brief introduction on the literary production of Kathy Acker and a brief overview on some essays where she shows the relation between writing and power, and between writing and desire, this paper analyzes the meaning of the act of plagiarism in one of her most experimental works: Great Expectation.

    By means of the concept of “desiring-machine” illustrated by Deleuze and Guattari in their essay L’Anti-Œdipe. Capitalisme et Schizophrénie, this paper intends to highlight the link between the use of plagiarism in Kathy Acker’s novel and the schizophrenic thought elaborated by the two French theorists.

    Dopo una breve introduzione intorno alla produzione letteraria di Kathy Acker e dopo una panoramica su alcuni saggi in cui l’autrice si sofferma sulla stretta relazione esistente tra scrittura e potere, e tra scrittura e desiderio, l’articolo esamina il significato assunto dal plagio in una delle sue opere più sperimentali: Great Expectations.

    Prendendo le mosse da un concetto centrale nella riflessione elaborata da Deleuze e Guattari all’interno del loro L’Anti-Œdipe. Capitalisme et Schizophrénie, come quello di “macchina desiderante”, questo contributo intende illustrare la relazione esistente tra l’atto del plagio e il pensiero schizofrenico elaborato dai due pensatori francesi.

    1983-04-08

    The imidazopyridines EMD 35993 and EMD 41717 antagonized the anticonflict actions of diazepam and chlordiazepoxide in rodent models which are predictive for anxiolytic action in man. In contrast to other described benzodiazepine antagonists, these compounds did not antagonize either the anticonvulsant or muscle relaxant properties of either benzodiazepine. Both EMD 39593 and EMD 41717 competitively inhibit the binding of [3H]diazepam to brain membranes, but do not exhibit regional differences in potency. These observations suggest that both EMD 39593 and EMD 41717 display some selectivity in antagonizing the anxiolytic properties of benzodiazepines, and as such may be useful tools in identifying neuronal substrates of anxiety.

  10. What makes men and women identify with Judith? A Jungian mythological perspective on the feminist value of Judith today

    Directory of Open Access Journals (Sweden)

    Helen Efthimiadis-Keith

    2012-08-01

    Full Text Available Inspired by her student’s overwhelmingly positive interpretation of Judith as a model for women’s liberation in diverse African contexts – despite the debate around the feminist value of Judith-Judith – the author deals with what could possibly allow men and women, particularly the latter, to interpret Judith positively today. Given her interest in Jungian individuation theory and Ancient Near Eastern (ANE mythology, the author investigates the subject matter by exploring Judith’s relation to male and female individuation patterns, the myths of the hero’s quest and Demeter-Kore, and ANE warrior-goddess myths.

    2006-01-01

    Empirical mode decomposition (EMD) is an adaptive and approximately orthogonal filtering process that reflects human's visual mechanism of differentiating textures. In this paper, we present a modified 2D EMD algorithm using the FastRBF and an appropriate number of iterations in the shifting process (SP), then apply it to texture classification. Rotation-invariant texture feature vectors are extracted using auto-registration and circular regions of magnitude spectra of 2D fast Fourier transform(FFT). In the experiments, we employ a Bayesion classifier to classify a set of 15 distinct natural textures selected from the Brodatz album. The experimental results, based on different testing datasets for images with different orientations, show the effectiveness of the proposed classification scheme.

    2016-01-01

    Judith was a legendary Hebrew heroine who beheaded the general Holofernes and saved the children of Israel from destruction by the Assyrian army. In the Book of Judith, which is still present in the Catholic and Orthodox Christian Bibles, Judith is presented as an illustrious woman who defeated the enemy using her virtue and fortitude. The present investigation has revealed 24 portraits in which Judith has been depicted with variable grades of thyroid gland enlargement on the scene where she decapitates Holofernes. There is no doubt that the integration of a slight thyroid enlargement in the paintings is a stylistic hallmark that portrays an idealized female beauty with a balanced neck and graceful body. The large extended goiter was probably depicted by the artists as a symbol of a powerful masculine body and her courage, and at the same time, it probably also reflects better anatomic accuracy and knowledge of artists from that period.

    2016-04-01

    Full Text Available Narratives are never meant to be neutral in their rhetorical intent. They have power not onlyto reveal realities and prevail worldviews but also to create new realities and new worldviewsby refuting illusions and falsehood, and affirming the truth. The Judith narrative is a goodexample for the exploration of this claim. This article contributes by employing the thematiclevel of analysis, the veridictory square in particular, of the Greimassian approach to narratives,to map out the possible illusions and affirming the truth within the second temple Judaism.The study of the veridictory square as informed by the level of analysis, mentioned above,seems to persuade the reader by first, extracting the truth from illusion and thereafter exposingand shaming falsehood in Judith. Subsequently, the article asserts that Judith is not neutral in itsintent but was designed to deal with illusive ideas that might have been impacting the wellbeingof the second temple Judaism.

  8. Ultrasonic flaw detection using EMD-based signal processing

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    The precise detection of flaw echoes buried in backscattering noise caused by material microstructure is a problem of great importance in ultrasonic non-destructive testing (NDT). In this work, empirical mode decomposition (EMD) is proposed to deal with ultrasonic signal. A time-frequency filtering method based on EMD is designed to suppress noise and enhance flaw signals. Simulated results are presented,showing that the proposed method has an excellent performance even for a very low signal-to-noise ratio(SNR). The improvement in flaw detection was experimentally verified using stainless steel pipe sample with artificial flaws.

  9. Hydrogeology of the Judith River Formation in southwestern Saskatchewan, Canada

    2017-06-01

    The Judith River Formation forms an important regional aquifer in southwestern Saskatchewan, Canada. This aquifer is used for domestic and agricultural purposes in some areas and supports oil and gas production in other areas. As a result, the available data come from a range of sources and integration is required to provide an overview of aquifer characteristics. Here, data from oil and gas databases are combined with data from groundwater resource assessments. Analysis of cores, drill-stem tests and pumping tests provide a good overview of the physical hydrogeology of the Judith River Aquifer. Water chemistry data from oil and gas databases were less helpful in understanding the chemical hydrogeology due contamination of samples and unreliable laboratory analyses. Analytical modeling of past pumping in the aquifer indicates that decreases in hydraulic head exceeding 2 m are possible over distances of 10s of kilometers. Similar decreases in head should be expected for additional large withdrawals of groundwater from the Judith River Aquifer. Long-term groundwater abstraction should be limited by low pumping rates. Higher pumping rates appear to be possible for short-term uses, such as those required by the oil and gas industry.

  10. EMD-based GPS baseline solution and validation test

    2008-01-01

    A GPS baseline solution model is presented, based on the Empirical Mode Decomposition (EMD), which has the advantage of eliminating the error effects outside the model. The EMD technique is a new signal processing method for non-linear time series, which decomposes a time series into a finite and often small number of Intrinsic Mode Functions (IMFs). The decomposition procedure is adaptive and data-driven which is suitable for non-linear data series analysis. A multi-scale decomposition and reconstruction architecture is defined on the basis of the EMD theory and the error mitigation model is demonstrated as well. A standard of the scale selection for the elimination of errors, outside the model, was given in terms of the mean of the accumulated standardized modes. Thereafter, the scheme of the GPS baseline solution based on the EMD is suggested. The float solution residuals of the Double-Difference (DD) observation equation are used to extract the errors outside the model applied to modify the GPS DD measurements. Then the float solution was given again and the fixed solution was obtained by a Lambda algorithm. Three schemes are designed to test the proposed model and the experimental results show that the proposed model dramatically improves the relia- bility of ambiguity resolution after the elimination of errors outside the model.

  11. RESEARCH ON THEORETIC EVIDENCE AND REALIZATION OF DIRECTLY-MEAN EMD METHOD

    Institute of Scientific and Technical Information of China (English)

    Zhong Youming; Qin Shuren; Tang Baoping

    2004-01-01

    Emprical mode decomposition(EMD) is a method and principle of decomposing signal dealing with Hilbert-Huang transform (HHT) in signal analysis, while directly-mean EMD is an improved EMD method presented by N.E.Huang, the inventor of HHT, which is aimed at solving the problems of EMD principle. Although the directly-mean EMD method is very remarkable with its advantages and N. E. Huang has given a method to realize it, he did not find the theoretic evidence of the method so that the feasibility of the idea and correctness of realizing the directly-mean EMD method is still indeterminate. For this a deep research on the forming process of complex signal is made and the involved stationary point principle and asymptotic stationary point principle are demonstrated, thus some theoretic evidences and the correct realizing way of directly-mean EMD method is firstly presented. Some simulation examples for demonstrating the idea presented are given.

  12. Directional EMD and its application to texture segmentation

    Institute of Scientific and Technical Information of China (English)

    LIU Zhongxuan; PENG Silong

    2005-01-01

    In this paper we present the definition and framework of Directional Empirical Mode Decomposition (DEMD) and use DEMD to do texture segmentation. As a new technique of time-frequency analysis, EMD decomposes signals by sifting and then analyzes the instantaneous frequency of the obtained components called Intrinsic Mode Functions (IMFs). Compared with Bidimensional EMD (BEMD) which only extracts textures by radial basis function interpolation, the virtues of DEMD include: the directional quality is considered in this framework; four features can be extracted for each point from the decomposition. The technique of selecting directions for DEMD based on texture's Wold theory is also presented. Experimental results indicate the effectiveness of the method for texture segmentation. In addition, we show the explanation for the DEMD's ability for texture classification from visual views.

  14. Ideology and intertextuality: Intertextual allusions in Judith 16

    Directory of Open Access Journals (Sweden)

    S. Philip Nolte

    2011-03-01

    Full Text Available This article utilised the theory of intertextuality to investigate the way in which religious texts, specifically Judith 16, generate meaning in the act of the production of texts. The groundbreaking work on intertextuality done by Julia Kristeva served as the theoretical point of departure. Kristeva utilised Mikhail Bakhtin’s literary theory to develop her own views on intertextuality. According to the theory of intertextuality, all texts are intersections of different texts and are therefore polyvalent. The article argued that the ideology (or ideologies of author(s of texts underpin the ways in which other texts are used and alluded to. The purpose of the investigation was to illustrate how intertextual allusions in Judith 16 are used to describe ‘God/the Lord’ as a God of war and, thereby, to maintain an already existing ideology of war:We know now that a text is not a line of words releasing a single ‘theological’ meaning (the ‘message’ of the Author-God but a multi-dimensional space in which a variety of writings, none of them original, blend and clash. The text is a tissue of quotations drawn from the innumerable centres of culture. (Barthes, cited in Beal 1992:27

    2016-01-01

    Empirical mode decomposition (EMD) is a data-driven signal analysis method for nonlinear and nonstationary data. Since it is intuitive, direct, posterior and adaptive, EMD is widely applied to various fields of study. In this paper, EMD and ensemble empirical mode decomposition (EEMD), a modified method of EMD, are applied to financial time series. Through analyzing the intrinsic mode functions (IMFs) of EMD and EEMD, we find EEMD method performs better on the orthogonality of IMFs than EMD. With clustering the ordered frequencies of IMFs, the IMFs obtained from EEMD method are grouped into high-, medium-, and low-frequency components, representing the short-, medium-, and long-term volatilities of the index sequences, respectively. With the cross-correlation analysis of DCCA cross-correlation coefficient, our findings allow us to gain further and detailed insight into the cross-correlations of stock markets.

    Full Text Available In a current procedure for periodontal tissue regeneration, enamel matrix derivative (EMD, which is the active component, is mixed with a propylene glycol alginate (PGA gel carrier and applied directly to the periodontal defect. Exposure of EMD to physiological conditions then causes it to precipitate. However, environmental changes during manufacture and storage may result in modifications to the conformation of the EMD proteins, and eventually premature phase separation of the gel and a loss in therapeutic effectiveness. The present work relates to efforts to improve the stability of EMD-based formulations such as Emdogain™ through the incorporation of arginine, a well-known protein stabilizer, but one that to our knowledge has not so far been considered for this purpose. Representative EMD-buffer solutions with and without arginine were analyzed by 3D-dynamic light scattering, UV-Vis spectroscopy, transmission electron microscopy and Fourier transform infrared spectroscopy at different acidic pH and temperatures, T, in order to simulate the effect of pH variations and thermal stress during manufacture and storage. The results provided evidence that arginine may indeed stabilize EMD against irreversible aggregation with respect to variations in pH and T under these conditions. Moreover, stopped-flow transmittance measurements indicated arginine addition not to suppress precipitation of EMD from either the buffers or the PGA gel carrier when the pH was raised to 7, a fundamental requirement for dental applications.

Representative EMD-buffer solutions with and without arginine were analyzed by 3D-dynamic light scattering, UV-Vis spectroscopy, transmission electron microscopy and Fourier transform infrared spectroscopy at different acidic pH and temperatures, T, in order to simulate the effect of pH variations and thermal stress during manufacture and storage. The results provided evidence that arginine may indeed stabilize EMD against irreversible aggregation with respect to variations in pH and T under these conditions. Moreover, stopped-flow transmittance measurements indicated arginine addition not to suppress precipitation of EMD from either the buffers or the PGA gel carrier when the pH was raised to 7, a fundamental requirement for dental applications.

    This paper analyzes the Raman spectrum and Near Infrared Spectrum (NIR) with time-frequency method. The empirical mode decomposition spectrum becomes intrinsic mode functions, which the proportion calculation reveals the Raman spectral energy is uniform distributed in each component, while the NIR's low order intrinsic mode functions only undertakes fewer primary spectroscopic effective information. Both the real spectrum and numerical experiments show that the empirical mode decomposition (EMD) regard Raman spectrum as the amplitude-modulated signal, which possessed with high frequency adsorption property; and EMD regards NIR as the frequency-modulated signal, which could be preferably realized high frequency narrow-band demodulation during first-order intrinsic mode functions. The first-order intrinsic mode functions Hilbert transform reveals that during the period of empirical mode decomposes Raman spectrum, modal aliasing happened. Through further analysis of corn leaf's NIR in time-frequency domain, after EMD, the first and second orders components of low energy are cut off, and reconstruct spectral signal by using the remaining intrinsic mode functions, the root-mean-square error is 1.001 1, and the correlation coefficient is 0.981 3, both of these two indexes indicated higher accuracy in re-construction; the decomposition trend term indicates the absorbency is ascending along with the decreasing to wave length in the near-infrared light wave band; and the Hilbert transform of characteristic modal component displays, 657 cm⁻¹ is the specific frequency by the corn leaf stress spectrum, which could be regarded as characteristic frequency for identification.

    Full Text Available Gears are the most essential parts in rotating machinery. Crack fault is one of damage modes most frequently occurring in gears. So, this paper deals with the problem of different crack levels classification. The proposed method is mainly based on empirical mode decomposition (EMD and Euclidean distance technique (EDT. First, vibration signal acquired by accelerometer is processed by EMD and intrinsic mode functions (IMFs are obtained. Then, a correlation coefficient based method is proposed to select the sensitive IMFs which contain main gear fault information. And energy of these IMFs is chosen as the fault feature by comparing with kurtosis and skewness. Finally, Euclidean distances between test sample and four classes trained samples are calculated, and on this basis, fault level classification of the test sample can be made. The proposed approach is tested and validated through a gearbox experiment, in which four crack levels and three kinds of loads are utilized. The results show that the proposed method has high accuracy rates in classifying different crack levels and may be adaptive to different conditions.

    2016-11-01

    Wind turbine blades are both the source of power and the core technology of wind generators. After long periods of time or in some extreme conditions, cracks or damage can occur on the surface of the blades. If the wind generators continue to work at this time, the crack will expand until the blade breaks, which can lead to incalculable losses. Therefore, a crack diagnosis method based on EMD for wind turbine blades is proposed in this paper. Based on aerodynamics and fluid-structure coupling theory, an aero-elastic analysis on wind turbine blades model is first made in ANSYS Workbench. Second, based on the aero-elastic analysis and EMD method, the blade cracks are diagnosed and identified in the time and frequency domains, respectively. Finally, the blade model, strain gauge, dynamic signal acquisition and other equipment are used in an experimental study of the aero-elastic analysis and crack damage diagnosis of wind turbine blades to verify the crack diagnosis method proposed in this paper.

    2015-12-01

    Full Text Available Joyce Carol Oates’s short story “My Warszawa: 1980” follows the journey of well-respected academician Judith Horne as she travels to and within Poland to participate in an international conference on American culture. She has a vague connection to Poland, with remote family members who were killed in Auschwitz and a Jewish ancestry that can be seen in her features, but she considers these facts unimportant to who she is at the moment. She travels with her lover, who is as remote emotionally as her dead forbears are physically. The emotional connections she makes with the people and land begin to affect her well-ordered and controlled life, including her relationship with him. As they sit side by side on the plane to Poland, he attends to his work as journalist, typewriter on his lap, and Judith gazes at the landscape, an opened book on hers. It is Henry James’s The Awkward Age, unread, chosen by Judith with a logic she cannot recall. Why does Oates give James to Judith, and why does she choose this novel in particular to influence her? Nanda’s story is a warning to Judith, a red flag that unfolds as the younger girl’s ruin proceeds before her eyes, and Judith realizes that the man she loves will never marry her, just as Vanderbank refuses to propose to Nanda. Neither man is comfortable with a woman who is corrupted by knowledge that might undermine his need for authority in the relationship. Nanda understands her position too late, but Judith has time to reflect on her situation, and Oates leaves the story unfinished, with Judith on a plane home with Carl but not definitively resigned to the relationship.

    Full Text Available According to the non-stationary property of vibration signal, the vibration signal is decomposed by empirical mode decomposition (EMD. And this method is applied to study the remanufacturing level of engine. Based on the decomposition of vibration signal, correlation coefficient is introduced to study the correlation between IMF (Intrinsic Mode Function components and original signal, and dynamic structure of IMF components is analyzed by correlation dimension. In order to study the remanufacturing level of engine, correlation coefficient and correlation dimension are considered in the function of IMF, and an index of vibration intensity is proposed. A corresponding relationship is established between remanufacturing level and vibration intensity. This method has been proved that the running state of engine can be reflected by vibration intensity, and this index can be used to evaluate the remanufacturing level of engine.

  9. Judith Butler's theories: reflections for nursing research and practice.

    2016-10-01

    Judith Butler is one of the most influential late 20th and early 21st century philosophers in regard to left wing politics, as well as an active campaigner for social justice within the United States and worldwide. Her academic work has been foundational to the academic discipline of queer theory and has been extensively critiqued and applied across a hugely wide range of disciplines. In addition, Butler's work itself is extensive covering topics such as gender, sexuality, race, literary theory, and warfare. This article can only serve as a taster for the potential application of her work in relation to nursing, which is in its infancy. This introduction covers three of the potentially most productive themes in Butler's work, namely power, performativity, and ethics. Each of these themes are critically explored in turn, sometimes in relation to their actual application in nursing literature, but also in relation to their potential for producing novel critiques of nursing practice. Suggestions are made about how Butler's work can develop nursing research and practice. The article concludes with a short summary of Butler's key works as well as suggested reading for people interested in examining how her theories have been applied across different academic settings.

  10. Holography and hydrodynamics for EMD theory with two Maxwell fields

    2013-01-01

    We use `generalized dimensional reduction' to relate a specific Einstein-Maxwell-Dilaton (EMD) theory, including two gauge fields, three neutral scalars and an axion, to higher-dimensional AdS gravity (with no higher-dimensional Maxwell field). In general, this is a dimensional reduction over compact Einstein spaces in which the dimension of the compact space is continued to non-integral values. Specifically, we perform a non-diagonal Kaluza-Klein (KK) reduction over a torus, involving two KK gauge fields. Our aim is to determine the holographic dictionary and hydrodynamic behaviour of the lower-dimensional theory by performing the generalized dimensional reduction on AdS. We study a specific example of a black brane carrying a wave, whose universal sector is described by gravity coupled to two Maxwell fields, three neutral scalars and an axion, and compute the first order transport coefficients of the dual theory. In these theories $\\hat{\\z}_s / \\hat{\\eta} < 2(1(d-1)-\\hat{c}_s^2)$, where $\\hat{c}_s$ is th...

  11. Cathodic Polarization Coats Titanium Based Implant Materials with Enamel Matrix Derivate (EMD

    Full Text Available The idea of a bioactive surface coating that enhances bone healing and bone growth is a strong focus of on-going research for bone implant materials. Enamel matrix derivate (EMD is well documented to support bone regeneration and activates growth of mesenchymal tissues. Thus, it is a prime candidate for coating of existing implant surfaces. The aim of this study was to show that cathodic polarization can be used for coating commercially available implant surfaces with an immobilized but functional and bio-available surface layer of EMD. After coating, XPS revealed EMD-related bindings on the surface while SIMS showed incorporation of EMD into the surface. The hydride layer of the original surface could be activated for coating in an integrated one-step process that did not require any pre-treatment of the surface. SEM images showed nano-spheres and nano-rods on coated surfaces that were EMD-related. Moreover, the surface roughness remained unchanged after coating, as it was shown by optical profilometry. The mass peaks observed in the matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF MS analysis confirmed the integrity of EMD after coating. Assessment of the bioavailability suggested that the modified surfaces were active for osteoblast like MC3M3-E1 cells in showing enhanced Coll-1 gene expression and ALP activity.

    Full Text Available An intertextual analysis of the character of Achior in the book of Judith shows that the author of the book proposes a changed Judaean identity. The way in which he depicts the character of Judith and her alter ego, Achior, illustrates the author’s ideology that people like proselytes and marginalised widows are not only to be included in the society, but can even be the leaders of the community. A nationalistic and exclusivist approach is entwined in the narrative with an inclusivist viewpoint propagating a new identity for the people of that time.

  13. Does mode mixing matter in EMD-based highlight volume methods for hydrocarbon detection? Experimental evidence

    Xue, Ya-juan; Cao, Jun-xing; Du, Hao-kun; Zhang, Gu-lan; Yao, Yao

    2016-09-01

    Empirical mode decomposition (EMD)-based spectral decomposition methods have been successfully used for hydrocarbon detection. However, mode mixing that occurs during the sifting process of EMD causes the 'true' intrinsic mode function (IMF) to be extracted incorrectly and blurs the physical meaning of the IMF. We address the issue of how the mode mixing influences the EMD-based methods for hydrocarbon detection by introducing mode-mixing elimination methods, specifically ensemble EMD (EEMD) and complete ensemble EMD (CEEMD)-based highlight volumes, as feasible tools that can identify the peak amplitude above average volume and the peak frequency volume. Three schemes, that is, using all IMFs, selected IMFs or weighted IMFs, are employed in the EMD-, EEMD- and CEEMD-based highlight volume methods. When these methods were applied to seismic data from a tight sandstone gas field in Central Sichuan, China, the results demonstrated that the amplitude anomaly in the peak amplitude above average volume captured by EMD, EEMD and CEEMD combined with Hilbert transforms, whether using all IMFs, selected IMFs or weighted IMFs, are almost identical to each other. However, clear distinctions can be found in the peak frequency volume when comparing results generated using all IMFs, selected IMFs, or weighted IMFs. If all IMFs are used, the influence of mode mixing on the peak frequency volume is not readily discernable. However, using selected IMFs or a weighted IMFs' scheme affects the peak frequency in relation to the reservoir thickness in the EMD-based method. Significant improvement in the peak frequency volume can be achieved in EEMD-based highlight volumes using selected IMFs. However, if the weighted IMFs' scheme is adopted (i.e., if the undesired IMFs are included with reduced weights rather than excluded from the analysis entirely), the CEEMD-based peak frequency volume provides a more accurate reservoir thickness estimate compared with the other two methods. This

    Thermal conductivity of a material can be comprehended as being composed of microscopic building blocks relevant to the energy transfer due to a specific microscopic process or structure. The building block is called the partial thermal conductivity (PTC). The concept of PTC is essential to evaluate the contributions of various molecular mechanisms to heat conduction and has been providing detailed knowledge of the contribution. The PTC can be evaluated by equilibrium molecular dynamics (EMD) and non-equilibrium molecular dynamics (NEMD) in different manners: the EMD evaluation utilizes the autocorrelation of spontaneous heat fluxes in an equilibrium state whereas the NEMD one is based on stationary heat fluxes in a non-equilibrium state. However, it has not been fully discussed whether the two methods give the same PTC or not. In the present study, we formulate a Green-Kubo relation, which is necessary for EMD to calculate the PTCs equivalent to those by NEMD. Unlike the existing theories, our formulation is based on the local equilibrium hypothesis to describe a clear connection between EMD and NEMD simulations. The equivalence of the two derivations of PTCs is confirmed by the numerical results for liquid methane and butane. The present establishment of the EMD-NEMD correspondence makes the MD analysis of PTCs a robust way to clarify the microscopic origins of thermal conductivity.

  6. A Fault Diagnosis Approach for Broken Rotor Bars Based on EMD and Envelope Analysis

    ZHANG Jian-wen; ZHU Ning-hui; YANG Li; YAO Qi; LU Qing

    2007-01-01

    Empirical Mode Decomposition (EMD) used to deal with non-linear and non-stable signals, is a time-frequency analytical method that has been developed recently. In this paper the EMD method is used to filter the noise from the stator current signal that arises when rotor bars break. Then a Hilbert Transform is used to extract the envelope from the filtered signal. With the EMD method again, the frequency band containing the fault characteristic-frequency components, 2sf, can be extracted from the signal's envelope. The last step is to use a Fast Fourier Transform (FFT) method to extract the fault characteristic frequency. This frequency can be detected in actual data from a faulty motor, as shown by example. Compared to the Extend Park Vector method this method is proved to be more sensitive under light motor load.

    Full Text Available This paper introduces a method for feature extraction and emotion recognition based on empirical mode decomposition (EMD. By using EMD, EEG signals are decomposed into Intrinsic Mode Functions (IMFs automatically. Multidimensional information of IMF is utilized as features, the first difference of time series, the first difference of phase, and the normalized energy. The performance of the proposed method is verified on a publicly available emotional database. The results show that the three features are effective for emotion recognition. The role of each IMF is inquired and we find that high frequency component IMF1 has significant effect on different emotional states detection. The informative electrodes based on EMD strategy are analyzed. In addition, the classification accuracy of the proposed method is compared with several classical techniques, including fractal dimension (FD, sample entropy, differential entropy, and discrete wavelet transform (DWT.

    Full Text Available A B-spline empirical mode decomposition (BEMD method is proposed to improve the celebrated empirical mode decomposition (EMD method. The improvement of BEMD on EMD mainly concentrates on the sifting process. First, instead of the curve that resulted from computing the average of upper and lower envelopes, the curve interpolated by the midpoints of local maximal and minimal points is used as the mean curve, which can reduce the cost of computation. Second, the cubic spline interpolation is replaced with cubic B-spline interpolation on account of the advantages of B-spline over polynomial spline. The effectiveness of BEMD compared with EMD is validated by numerical simulations and an application to find the basis functions of EMI signals.

    Awajan, Ahmad Mohd; Ismail, Mohd Tahir

    2017-08-01

    Recently, forecasting time series has attracted considerable attention in the field of analyzing financial time series data, specifically within the stock market index. Moreover, stock market forecasting is a challenging area of financial time-series forecasting. In this study, a hybrid methodology between Empirical Mode Decomposition with the Holt-Winter method (EMD-HW) is used to improve forecasting performances in financial time series. The strength of this EMD-HW lies in its ability to forecast non-stationary and non-linear time series without a need to use any transformation method. Moreover, EMD-HW has a relatively high accuracy and offers a new forecasting method in time series. The daily stock market time series data of 11 countries is applied to show the forecasting performance of the proposed EMD-HW. Based on the three forecast accuracy measures, the results indicate that EMD-HW forecasting performance is superior to traditional Holt-Winter forecasting method.

    2005-03-01

    The interaction of hot plasma with material in fusion devices can result in material erosion and irreversible damage. Carbon based materials are proposed for ITER divertor armour. To simulate carbon erosion under high heat fluxes, electron beam heating in the JUDITH facility has been used. In this paper, carbon erosion under energetic electron impact is modeled by the 3D thermomechanics code 'PEGASUS-3D'. The code is based on a crack generation induced by thermal stress. The particle emission observed in thermal shock experiments is a result of breaking bonds between grains caused by thermal stress. The comparison of calculations with experimental data from JUDITH shows good agreement for various incident power densities and pulse durations. A realistic mean failure stress has been found. Pre-heating of test specimens results in earlier onset of brittle destruction and enhanced particle loss in agreement with experiments.

    2015-05-01

    In this paper, the novel hybrid ensemble learning paradigm integrating ensemble empirical mode decomposition (EMD) and least square support machine (LSSVM) is proposed to improve the accuracy of fishery landing forecasting. This hybrid is formulated specifically to address in modeling fishery landing, which has high nonlinear, non-stationary and seasonality time series which can hardly be properly modelled and accurately forecasted by traditional statistical models. In the hybrid model, EMD is used to decompose original data into a finite and often small number of sub-series. The each sub-series is modeled and forecasted by a LSSVM model. Finally the forecast of fishery landing is obtained by aggregating all forecasting results of sub-series. To assess the effectiveness and predictability of EMD-LSSVM, monthly fishery landing record data from East Johor of Peninsular Malaysia, have been used as a case study. The result shows that proposed model yield better forecasts than Autoregressive Integrated Moving Average (ARIMA), LSSVM and EMD-ARIMA models on several criteria..

    2015-08-01

    Full Text Available During the measurement of friction force, the measured signal generally contains noise. To remove the noise and preserve the important features of the signal, a hybrid filtering method is introduced that uses the mutual information and a new waveform. This new waveform is the difference between the original signal and the sum of intrinsic mode functions (IMFs, which are obtained by empirical mode decomposition (EMD or its improved versions. To evaluate the filter performance for the friction signal, ensemble EMD (EEMD, complementary ensemble EMD (CEEMD, and complete ensemble EMD with adaptive noise (CEEMDAN are employed in combination with the proposed filtering method. The combination is used to filter the synthesizing signals at first. For the filtering of the simulation signal, the filtering effect is compared under conditions of different ensemble number, sampling frequency, and the input signal-noise ratio, respectively. Results show that CEEMDAN outperforms other signal filtering methods. In particular, this method is successful in filtering the friction signal as evaluated by the de-trended fluctuation analysis (DFA algorithm.

    Full Text Available O texto expõe o ponto de vista de duas grandes filósofas feministas da atualidade, Adriana Cavarero e Judith Butler, sobre subjetividade e relacionalidade, mostrando como ambas distanciaram-se dos temas específicos do feminismo de maneira a aprofundar e ampliar suas reflexões sobre política e ética. Questionando a tradição, Cavarero não compactua nem com o binarismo metafísico nem com a impessoalidade pós-moderna, combinando uma perspectiva feminista com a arendtiana da subjetividade embasada na relacionalidade. No entanto, diferentemente do pensamento de Cavarero, sob a perspectiva desconstrucionista de Butler a linguagem molda corpo e identidade. A subjetividade está presa às normas e valores sociais. Butler e Cavarero repensam a subjetividade, alinhando-se quanto à relacionalidade, ou seja, deslocando a política para longe do ser imune e realocando-a no ser vulnerável em relação com o outro e com os efeitos das regras e valores sociais impostos.The work presents the standpoint of two important contemporary feminist philosophers, Adriana Cavarero and Judith Butler, on subjectivity and relationality, showing how both moved away from the specific feminism motif in order to deepen and broaden their reflection on politics and ethics. Calling tradition into question, Cavarero agrees neither with the metaphysical binary, nor with the post-modern impersonality, combining a feminist and the arendtian perspectives of the subjectivity based on relationality. Contrary to Cavarero's thought, though, under Butler's deconstructionist standpoint language shapes body and identity. Subjectivity is "trapped" into social norms and values. Both Butler and Cavarero rethink subjectivity based on relationality, that is, displacing politics from the immune individual and reallocating it on the vulnerable individual in relation with the other and with the social rules and values imposed on them.

In the proposed method, first, we extract the detailed features of a PIR signal into five symbol sequences using an EMD-based symbolization method, then, we generate five feature descriptors for each PIR signal through constructing five probabilistic finite state automata with the symbol sequences. Finally, we use a weighted voting classification strategy to classify the PIR signals with their feature descriptors. Comparative experiments show that the proposed method can effectively classify the human and nonhuman PIR signals and reduce PIR detector’s false alarms.

  2. EMD and Wavelet Transform Based Fault Diagnosis for Wind Turbine Gear Box

    2013-01-01

    Full Text Available Wind turbines are mainly located in harsh environment, and the maintenance is therefore very difficult. The wind turbine faults are mostly from the gear box, and the fault signal is generally nonlinear and nonstationary. The traditional fault diagnosis methods such as Fast Fourier transform (FFT and the inverted frequency spectrum identification method based on FFT are not satisfactory in processing this kind of signal. This paper proposes a hybrid fault diagnosis method which combines the empirical mode decomposition (EMD and wavelet transform. The vibration signal is analyzed through wavelet transform, and the aliasing in high-frequency signals is then addressed by conducting EMD to the original signals. The experimental results based on a specific wind turbine gear box demonstrate that this method can diagnose the faults and locate their positions accurately.

    Emery-Dreifuss muscular dystrophy (EDMD) is caused by mutations in the EMD gene on the X chromosome, which codes for emerin, an inner nuclear membrane protein. Monoclonal antibodies against the N-terminus of emerin protein are used to screen for emerin deficiency in clinical practice. However, these tests may not accurately reflect the disease in some cases. We herein describe the identification of a splice site mutation in the EMD gene in a Japanese patient who suffered from complete atrioventricular conduction block, mild muscle weakness and joint contracture, and a persistently elevated serum creatine kinase level. We used multiple antibodies to confirm the presence of a novel truncating mutation in emerin without the transmembrane region and C-terminus in the skeletal muscle.

    The Empirical Mode Decomposition (EMD) and Auto-Regressive model (AR) are applied to a long-term prediction of sunspot numbers. With the sample data of sunspot numbers from 1848 to 1992, the method is evaluated by examining the measured data of the solar cycle 23 with the prediction: different time scale components are obtained by the EMD method and multi-step predicted values are combined to reconstruct the sunspot number time series. The result is remarkably good in comparison to the predictions made by the solar dynamo and precursor approaches for cycle 23. Sunspot numbers of the coming solar cycle 24 are obtained with the data from 1848 to 2007, the maximum amplitude of the next solar cycle is predicted to be about 112 in 2011-2012.

    2016-01-01

    Full Text Available Vibration signals resulting from railway rolling bearings are nonstationary by nature; this paper proposes a hybrid approach for the fault diagnosis of railway rolling bearings using segment threshold wavelet denoising (STWD, empirical mode decomposition (EMD, genetic algorithm (GA, and least squares support vector machine (LSSVM. The original signal is first denoised using STWD as a prefilter, which improves the subsequent decomposition into a number of intrinsic mode functions (IMFs using EMD. Secondly, the IMF energy-torques are extracted as feature parameters. Concurrently, a GA is employed to optimize the LSSVM to improve the classification accuracy. Finally, the extracted features are used as inputs for classification by the GA-LSSVM. Actual railway rolling bearing vibration signals are used to experimentally verify the effectiveness of the proposed method. The results show that the novel method is effective and accurate for fault diagnosis of railway rolling bearings.

    2016-01-01

    This paper presents a novel method for feature extraction from electroencephalogram (EEG) signals using empirical mode decomposition (EMD). Its use is motivated by the fact that the EMD gives an effective time-frequency analysis of nonstationary signals. The intrinsic mode functions (IMF) obtained as a result of EMD give the decomposition of a signal according to its frequency components. We present the usage of upto third order temporal moments, and spectral features including spectral centroid, coefficient of variation and the spectral skew of the IMFs for feature extraction from EEG signals. These features are physiologically relevant given that the normal EEG signals have different temporal and spectral centroids, dispersions and symmetries when compared with the pathological EEG signals. The calculated features are fed into the standard support vector machine (SVM) for classification purposes. The performance of the proposed method is studied on a publicly available dataset which is designed to handle various classification problems including the identification of epilepsy patients and detection of seizures. Experiments show that good classification results are obtained using the proposed methodology for the classification of EEG signals. Our proposed method also compares favorably to other state-of-the-art feature extraction methods.

  11. Use of Knowledge Base Systems (EMDS) in Strategic and Tactical Forest Planning

    2008-12-01

    The USDA Forest Service 2008 Planning Rule requires Forest plans to provide a strategic vision for maintaining the sustainability of ecological, economic, and social systems across USFS lands through the identification of desired conditions and objectives. In this paper we show how knowledge-based systems can be efficiently used to evaluate disparate natural resource information to assess desired conditions and related objectives in Forest planning. We use the Ecosystem Management Decision Support (EMDS) system (http://www.institute.redlands.edu/emds/), which facilitates development of both logic-based models for evaluating ecosystem sustainability (desired conditions) and decision models to identify priority areas for integrated landscape restoration (objectives). The study area for our analysis spans 1,057 subwatersheds within western Montana and northern Idaho. Results of our study suggest that knowledge-based systems such as EMDS are well suited to both strategic and tactical planning and that the following points merit consideration in future National Forest (and other land management) planning efforts: 1) Logic models provide a consistent, transparent, and reproducible method for evaluating broad propositions about ecosystem sustainability such as: are watershed integrity, ecosystem and species diversity, social opportunities, and economic integrity in good shape across a planning area? The ability to evaluate such propositions in a formal logic framework also allows users the opportunity to evaluate statistical changes in outcomes over time, which could be very useful for regional and national reporting purposes and for addressing litigation; 2) The use of logic and decision models in strategic and tactical Forest planning provides a repository for expert knowledge (corporate memory) that is critical to the evaluation and management of ecosystem sustainability over time. This is especially true for the USFS and other federal resource agencies, which are

    By virtue of neural network, a series of signals is extended forward and backward, as a result, two additional maxima and two additional minima are obtained at both ends of the original data set, with which the EMD decomposition can be exactly achieved with cubic spline interpolation. Meanwhile, by using of neural network every IMF component can also be extended forward and backward, which effectively restrains the end effect, thus the veracious Hilbert spectra are achieved. Verifications of the sample signals and the actual surface elevation of sea waves show that the present extension method is relatively accurate.

    针对风速为非线性非平稳序列的特点,提出一种基于经验模态分解(empirical mode decomposition ,EMD)和自回归滑动平均模型(auto-regressive moving average model,ARMA)的预测方法。EMD 在对风速序列进行分解时,可能存在模态混叠现象,会影响风速预测精度,为此,提出一种加入高频谐波来抑制模态混叠的方法。首先对风速序列加入高频谐波进行 EMD 分解,获得比原始序列较平稳的子序列,即固有模态函数(intrinsic mode function,IMF),然后利用 ARMA 模型对子序列进行建模预测分析,最后将子序列的预测结果相加得到风速的预测值。和 EMD-ARMA 及直接利用 ARMA 模型进行预测的结果相比,本文所提的方法预测精度更高。%To forecast wind speed within shot-term,this paper proposes a prediction method based on Empirical Mode Decomposi-tion (EMD)and Auto-Regressive Moving Average model (ARMA)for the characteristics of the wind speed as the nonlinear and non-stationary sequence.When wind speed sequence is decomposed by EMD,there may be a mode mixing phenomenon,which will affect the accuracy of wind speed forecasting.Therefore,a method of adding high frequency harmonics to suppress the mode mixing is proposed in this paper.Firstly,high frequency harmonic is added to the wind speed series,then the method uses EMD to decompose it into a series of Intrinsic Mode Functions (IMFS)which are smoother than the original sequence.Secondly,the ARMA model is used to predict the subsequences.Finally,the prediction result of the wind speed is obtained by adding the pre-dicted results of the subsequences.The proposed method is more accurate than the result obtained by directly using EMD-ARMA and ARMA for wind speed sequence.

    In order to improve precision of prediction on short-term wind speed,a prediction model for short-term wind speed combining improved empirical model decomposition (EMD)and radial basis function neural network (RBFNN)is pro-posed.Firstly,extreme point symmetric extension is used for processing on preprocessed wind speed sequences so as to re-strain fringe effect in decomposition caused by traditional EMD,and piecewise cubic Hermite interpolation method is used to solve overshoot or undershoot of traditional EMD envelope lines.Then,improved EMD is used to decompose wind speed se-quences into different intrinsic mode function (IMF)components and respective RBFNN model is constructed for predic-tion.Finally,prediction results of various components are reconstructed and overlayed to get final predicted value of original wind speed.Experimental results indicate that the improved EMD-RBFNN prediction model is able to effectively improve precision of prediction on wind speed and has certain application value.%为提高短期风速预测精度,提出改进经验模态分解法(empirical mode decomposition,EMD)与径向基函数神经网络(radial basis function neural network,RBFNN)相结合的短期风速预测模型。首先,利用极值点对称延拓法对预处理过的风速序列进行处理,以抑制传统EMD在分解过程中所引起的边缘效应,并引用分段三次埃米特插值法解决传统EMD包络线的过冲或欠冲问题;然后,利用改进 EMD 将风速序列分解成各本征模态(in-trinsic mode function,IMF)分量,再针对各分量分别构建各自的 RBFNN 模型进行预测;最后,将各分量的预测结果进行重构、叠加,得到最终的原始风速预测值。实验结果表明,改进的 EMD-RBFNN 预测模型能有效地提高风速预测精度,并具有一定的应用价值。

    Full Text Available Targeting the characteristics that periodic impulses usually occur whilst the rotating machinery exhibits local faults and the limitations of singular value decomposition (SVD techniques, the SVD technique based on empirical mode decomposition (EMD is applied to the fault feature extraction of the rotating machinery vibration signals. The EMD method is used to decompose the vibration signal into a number of intrinsic mode functions (IMFs by which the initial feature vector matrices could be formed automatically. By applying the SVD technique to the initial feature vector matrices, the singular values of matrices could be obtained, which could be used as the fault feature vectors of support vector machines (SVMs classifier. The analysis results from the gear and roller bearing vibration signals show that the fault diagnosis method based on EMD, SVD and SVM can extract fault features effectively and classify working conditions and fault patterns of gears and roller bearings accurately even when the number of samples is small.

    Full Text Available Coal-gangue interface detection during top-coal caving mining is a challenging problem. This paper proposes a new vibration signal analysis approach to detecting the coal-gangue interface based on singular value decomposition (SVD techniques and support vector machines (SVMs. Due to the nonstationary characteristics in vibration signals of the tail boom support of the longwall mining machine in this complicated environment, the empirical mode decomposition (EMD is used to decompose the raw vibration signals into a number of intrinsic mode functions (IMFs by which the initial feature vector matrices can be formed automatically. By applying the SVD algorithm to the initial feature vector matrices, the singular values of matrices can be obtained and used as the input feature vectors of SVMs classifier. The analysis results of vibration signals from the tail boom support of a longwall mining machine show that the method based on EMD, SVD, and SVM is effective for coal-gangue interface detection even when the number of samples is small.

    Full Text Available Changes in the frequencies of cell subsets that (coexpress characteristic biomarkers, or levels of the biomarkers on the subsets, are widely used as indices of drug response, disease prognosis, stem cell reconstitution, etc. However, although the currently available computational "gating" tools accurately reveal subset frequencies and marker expression levels, they fail to enable statistically reliable judgements as to whether these frequencies and expression levels differ significantly between/among subject groups. Here we introduce flow cytometry data analysis pipeline which includes the Earth Mover's Distance (EMD metric as solution to this problem. Well known as an informative quantitative measure of differences between distributions, we present three exemplary studies showing that EMD 1 reveals clinically-relevant shifts in two markers on blood basophils responding to an offending allergen; 2 shows that ablative tumor radiation induces significant changes in the murine colon cancer tumor microenvironment; and, 3 ranks immunological differences in mouse peritoneal cavity cells harvested from three genetically distinct mouse strains.

    Full Text Available Nowadays, the fault diagnosis of rolling bearing in aeroengines is based on the vibration signal measured on casing, instead of bearing block. However, the vibration signal of the bearing is often covered by a series of complex components caused by other structures (rotor, gears. Therefore, when bearings cause failure, it is still not certain that the fault feature can be extracted from the vibration signal on casing. In order to solve this problem, a novel fault feature extraction method for rolling bearing based on empirical mode decomposition (EMD and the difference spectrum of singular value is proposed in this paper. Firstly, the vibration signal is decomposed by EMD. Next, the difference spectrum of singular value method is applied. The study finds that each peak on the difference spectrum corresponds to each component in the original signal. According to the peaks on the difference spectrum, the component signal of the bearing fault can be reconstructed. To validate the proposed method, the bearing fault data collected on the casing are analyzed. The results indicate that the proposed rolling bearing diagnosis method can accurately extract the fault feature that is submerged in other component signals and noise.

    The Ecosystem Management Decision Support (EMDS) system is an application framework for knowledge-based decision support of ecological assessments at any geographic scale. The system integrates state-of-the-art geographic information system(GIS) as well as knowledge-based reasoning and decision modeling technologies to provide decision support for a substantial portion of the adaptive management process of ecosystem management. EMDS 3.0 is implemented as an ArcMap(R) extension and integrates the logic engine of NetWeaver(R) to perform landscape evaluations, and the decision modeling engine of Criterium DecisionPlus(R) for evaluating management priorities. Key features of the system's evaluation component include abilities to (1) reason about large, abstract, multi-faceted ecosystem management problems, (2) perform useful evaluations with incomplete information, (3) evaluate the influence of missing information, and (4)determine priorities for missing information. A key feature of the planning component is the ability to determine priorities for management activities, taking into account not only ecosystem condition, but also criteria that account for the feasibility and efficacy of potential management actions. Both components include powerful and intuitive diagnostic features that facilitate communicating the explanation of modeling results to a broad audience.

    Electroencephalogram (EEG) is widely used for monitoring, diagnosis purposes and also for study of brain's physiological, mental and functional abnormalities. Processing of information by the brain is reflected in dynamical changes of the electrical activity in time, frequency, and space. EEG signal processing tends to describe and quantify these variations in such a way that they are localized in temporal, spectral and spatial domain. Here we use multi-way (Tensor) analysis for localizing the EEG events. We used EMD process for decomposing EEG into distinct oscillatory modes, which are then mapped to TF plane using the near optimal Reassigned Spectrogram. Temporal, Spatial and Spectral information of the Multichannel EEG are then used to generate a three-way Frequency-Time-Space EEG tensor. Exploiting EMD also enables us to detrend the EEG recordings. Simulation results on both synthetic and real EEG data show that tensor analysis greatly improve separation and localization of overlapping events in EEG and it could be effectively exploited for detecting and characterizing the evoked potentials.

    In this paper, a method using higher order statistical moments of EEG signals calculated in the empirical mode decomposition (EMD) domain is proposed for detecting seizure and epilepsy. The appropriateness of these moments in distinguishing the EEG signals is investigated through an extensive analysis in the EMD domain. An artificial neural network is employed as the classifier of the EEG signals wherein these moments are used as features. The performance of the proposed method is studied using a publicly available benchmark database for various classification cases that include healthy, interictal (seizure-free interval) and ictal (seizure), healthy and seizure, nonseizure and seizure, and interictal and ictal, and compared with that of several recent methods based on time-frequency analysis and statistical moments. It is shown that the proposed method can provide, in almost all the cases, 100% accuracy, sensitivity, and specificity, especially in the case of discriminating seizure activities from the nonseizure ones for patients with epilepsy while being much faster as compared to the time-frequency analysis-based techniques.

    In order to reduce the muscle artifacts in multi-channel pervasive Electroencephalogram (EEG) signals, we here propose and compare two hybrid algorithms by combining the concept of wavelet packet transform (WPT), empirical mode decomposition (EMD) and Independent Component Analysis (ICA). The signal cleaning performances of WPT-EMD and WPT-ICA algorithms have been compared using a signal-to-noise ratio (SNR)-like criterion for artifacts. The algorithms have been tested on multiple trials of four different artifact cases viz. eye-blinking and muscle artifacts including left and right hand movement and head-shaking.

    The receptor tyrosine kinase MET is a prime target in clinical oncology due to its aberrant activation and involvement in the pathogenesis of a broad spectrum of malignancies. Similar to other targeted kinases, primary and secondary mutations seem to represent an important resistance mechanism to MET inhibitors. Here, we report the biologic activity of a novel MET inhibitor, EMD1214063, on cells that ectopically express the mutated MET variants M1268T, Y1248H, H1112Y, L1213V, H1112L, V1110I, V1206L, and V1238I. Our results show a dose-dependent decrease in MET autophosphorylation in response to EMD1214063 in five of the eight cell lines (IC50 2-43 nmol/L). Blockade of MET by EMD1214063 was accompanied by a reduced activation of downstream effectors in cells expressing EMD1214063-sensitive mutants. In all sensitive mutant-expressing lines, EMD1214063 altered cell-cycle distribution, primarily with an increase in G1 phase. EMD1214063 strongly influenced MET-driven biologic functions, such as cellular morphology, MET-dependent cell motility, and anchorage-independent growth. To assess the in vivo efficacy of EMD1214063, we used a xenograft tumor model in immunocompromised mice bearing NIH3T3 cells expressing sensitive and resistant MET-mutated variants. Animals were randomized for the treatment with EMD1214063 (50 mg/kg/d) or vehicle only. Remarkably, five days of EMD1214063 treatment resulted in a complete regression of the sensitive H1112L-derived tumors, whereas tumor growth remained unaffected in mice with L1213V tumors and in vehicle-treated animals. Collectively, the current data identifies EMD1214063 as a potent MET small-molecule inhibitor with selective activity towards mutated MET variants. ©2013 AACR.

    2015-01-01

    Contrary to the aliasing defect between the adjacent intrinsic model functions (IMFs) existing in empirical model decomposition (EMD), a new method of detecting dynamic unbalance with cardan shaft in high-speed train was proposed by applying the combination between EMD, Hankel matrix, singular value decomposition (SVD) and normalized Hilbert transform (NHT). The vibration signals of gimbal installed base were decomposed through EMD to get different IMFs. The Hankel matrix constructed through the single IMF was orthogonally executed through SVD. The critical singular values were selected to reconstruct vibration signs on the basis of the key stack of singular values. Instantaneous frequencys (IFs) of reconstructed vibration signs were applied to detect dynamic unbalance with shaft and eliminated clutter spectrum caused by the aliasing defect between the adjacent IMFs, which highlighted the failure characteristics. The method was verified by test data in the unbalance condition of dynamic cardan shaft. The results show that the method effectively detects the fault vibration characteristics caused by cardan shaft dynamic unbalance and extracts the nature vibration features. With comparison to the traditional EMD-NHT, clarity and failure characterization force are significantly improved.

    Full Text Available The editors and editorial board of Human Organization are pleased to introduce readers to the following oral history interview with Michael M. Cernea, a development social scientist who has militated throughout his academic career and applied work for "putting people first", in the forefront of development projects and policies. Working for a long time for the promotion of anthropological and sociological knowledge, either in the activities of the World Bank or in the policies and programs of governments of both developed and developing countries, Dr. Cernea cleared pathways for applied social science that are sure to benefit people in development settings for many years to come. Undoubtedly many readers already know Dr. Cernea's work well, especially those of us who teach the anthropology of development or work in applied settings and organizations, but this interview embeds his broad body of work into a personal, human, and at times tragic context that opens with brushes with death, Nazi brutality, and exile. It also provides valuable insights for carrying out the work of development anthropologists within large-scale organizations and governments.This interview with Dr. Cernea was conducted by Dr. Judith Freidenberg, of the University of Maryland, on June 30, 2003, for the Society for Applied Anthropology Oral History Project, headquartered at the University of Kentucky Libraries. This Project aims to create, through the vehicle of oral histories, a record of the life, activities and experiences of number of selected scholars-anthropologists who devoted a great part of their scientific work to research, to applied work in different settings, to inducing development, including to hands-on work on crafting public social policies and actual development programs. The present transcript of the interview was reviewed by both participants for editorial purposes. Michael M. Cernea expanded some of his oral responses, for historical accuracy or to add

    Full Text Available In this paper we propose to look into different meanings of livability and life in Judith butler’s thought. Although crucial for her early work (she points to it in her 1999 Introduction to Gender Trouble, the concept of livability as such emerges more often and in a more pronounced manner in her later books (from Undoing Gender and Precarious life to Towards a Performative Theory of Assembly. Our main question is: what is the thread that runs through different concepts of life in butler’s work? What are the links between abject, unlivable, precarious, ungrievable, jettisoned and dispossessed life? this raises further questions: the question of gradation of livability (which life matters and ‘how much’, and how to think this quantifiability of something so unquantifiable; and the question of universality (all lives matter. these questions obviously need to take into account the terms under which a life is qualified and counted as livable. such conditions encompass the norms that organize the possibility of recognition and the orders of recognizability and differential allocation of humanness. they encompass the ways in which we are constituted politically, but also in which this ‘we’ is social and bodily. the question of livable life is thus very much entangled with the issue of (individual agency, but also with what we as agents require “in order to maintain and reproduce the conditions of (our own livability” (Undoing Gender 2004: 39.

    Full Text Available In this paper we take Judith Butler’s thinking as a basis from which to consider the ideas of three authors. In our view, these authors complement Butler’s project of helping excluded people to fight for a dignified life, a “liveable life”; and specifically to the idea of using performative resignifications of discourses and practices. On one hand, we present the writings of Sarah Ahmed and Lanei Rodemeyer; they consider the spatiality and temporality of the lived body (Ahmed and the relationship between the lived body and discourse (Rodemeyer. In both cases, “pure phenomenology” (and not hermeneutics is applied to the question of sexual diversity. On the other hand, we delve into the works of Louise Bourgeois, for whom artistic creation is a way of exorcising pain and becoming free of socially constructed prisons. Starting from the paths opened by these authors, we believe that a phenomenology is possible in which there is place for what does not fit into the norm. this phenomenology would make it possible, on one side, to rend visibility to those who do not fit into the established norms and categories and, on another side, to contribute to a reformulation of discourse, such a transformation that allows the excluded to inhabit them. “Pure” phenomenology, that aims at going to “the things themselves” do not naturalise oppressions, but it is rather an ally to recognise, denounce and provide a reparation for them.

    2005-01-01

    In this paper, response spectral characteristics of one-, two-, and three-lobe sinusoidal acceleration pulses are investigated, and some of their basic properties are derived. Furthermore, the empirical mode decomposition (EMD) method is utilized as an adaptive filter to decompose the near-fault pulse-like ground motions, which were recorded during the September 20, 1999, Chi-Chi earthquake. These ground motions contain distinct velocity pulses, and were decomposed into high-frequency (HF) and low-frequency (LF) components, from which the corresponding HF acceleration pulse (if existing)and LF acceleration pulse could be easily identified and detected. Finally, the identified acceleration pulses are modeled by simplified sinusoidal approximations, whose dynamic behaviors are compared to those of the original acceleration pulses as well as to those of the original HF and LF acceleration components in the context of elastic response spectra. It was demonstrated that it is just the acceleration pulses contained in the near-fault pulse-like ground motion that fundamentally dominate the special impulsive dynamic behaviors of such motion in an engineering sense. The motion thus has a greater potential to cause severe damage than the far-field ground motions, i.e. they impose high base shear demands on engineering structures as well as placing very high deformation demands on long-period structures.

    Noise may reduce the demodulation accuracy of fiber Bragg grating (FBG) sensing signal so as to affect the quality of sensing detection. Thus, the recovery of a signal from observed noisy data is necessary. In this paper, a precise self-adaptive algorithm of selecting relevant modes is proposed to remove the noise of signal. Empirical mode decomposition (EMD) is first used to decompose a signal into a set of modes. The pseudo modes cancellation is introduced to identify and eliminate false modes, and then the Mutual Information (MI) of partial modes is calculated. MI is used to estimate the critical point of high and low frequency components. Simulation results show that the proposed algorithm estimates the critical point more accurately than the traditional algorithms for FBG spectral signal. While, compared to the similar algorithms, the signal noise ratio of the signal can be improved more than 10 dB after processing by the proposed algorithm, and correlation coefficient can be increased by 0.5, so it demonstrates better de-noising effect.

    An investigation of Empirical Mode Decomposition (EMD) based noise filtering algorithm has been carried out on a mirror signal from a two fold germanium clover detector. EMD technique can decompose linear as well as nonlinear and chaotic signals with a precise frequency resolution. It allows to decompose the preamplifier signal (charge pulse) on an event-by-event basis. The filtering algorithm provides the information about the Intrinsic Mode Functions (IMFs) mainly dominated by the noise. It preserves the signal information and separates the overriding noise oscillations from the signals. The identification of noise structure is based on the frequency distributions of different IMFs. The preamplifier noise components which distort the azimuthal co-ordinates information have been extracted on the basis of the correlation between the different IMFs and the mirror signal. The correlation studies have been carried out both in frequency and time domain. The extracted correlation coefficient provides an important information regarding the pulse shape of the γ-ray interaction in the detector. A comparison between the EMD based and state-of-the-art wavelet based denoising techniques has also been made and discussed. It has been observed that the fractional noise strength distribution varies with the position of the collimated gamma-ray source. Above trend has been reproduced by both the denoising techniques.

    Judith Butler é mais conhecida como autora de Gender Trouble, no qual problematiza a maneira pela qual se pensava o gênero até então. A partir daí, ela publica diversas obras nas quais aprofunda e desenvolve sua filosofia, calcada em larga medida em considerações inicialmente propostas por Michel Foucault, partindo de sua noção de um poder produtivo dos sujeitos. Butler investiga os termos que desenham o campo de possibilidade dos sujeitos, desnudando como nossas noções de realidade são infor...

    Full Text Available This paper presents some general guidelines on the distinction sex/gender and its impact on the delimitation of the body category in feminist theory. Then, it offers some arguments that question the sexual dimorphism in natural terms from Judith Butler's psychoanalytic conceptualizations. According to this, essentialist and constructivist approaches are discussed in relation to the body, illustrated from Luce Irigaray and Judith Butler's proposals. Finally, it comes to the conclusion of the need to debate the sex category as a special occasion to reformulate the multiple conceptualizations involving the dimension of the body.

She concentrates on human rights and statutory provisions through which homosexual pairs are discriminated against in family planning. There exists a great need for a theoretically rich critique and for practical improvements. Butler exemplarily analyses the publically debated case of an operative sex change, in which neither the critics nor the supporters sufficiently notes the concerned person’s own wishes. The weakness of the volume lies in the ambiguous use of the term gender.

    Simultaneous electroencephalography (EEG) and functional magnetic resonance image (fMRI) acquisitions provide better insight into brain dynamics. Some artefacts due to simultaneous acquisition pose a threat to the quality of the data. One such problematic artefact is the ballistocardiogram (BCG) artefact. We developed a hybrid algorithm that combines features of empirical mode decomposition (EMD) with principal component analysis (PCA) to reduce the BCG artefact. The algorithm does not require extra electrocardiogram (ECG) or electrooculogram (EOG) recordings to extract the BCG artefact. The method was tested with both simulated and real EEG data of 11 participants. From the simulated data, the similarity index between the extracted BCG and the simulated BCG showed the effectiveness of the proposed method in BCG removal. On the other hand, real data were recorded with two conditions, i.e. resting state (eyes closed dataset) and task influenced (event-related potentials (ERPs) dataset). Using qualitative (visual inspection) and quantitative (similarity index, improved normalized power spectrum (INPS) ratio, power spectrum, sample entropy (SE)) evaluation parameters, the assessment results showed that the proposed method can efficiently reduce the BCG artefact while preserving the neuronal signals. Compared with conventional methods, namely, average artefact subtraction (AAS), optimal basis set (OBS) and combined independent component analysis and principal component analysis (ICA-PCA), the statistical analyses of the results showed that the proposed method has better performance, and the differences were significant for all quantitative parameters except for the power and sample entropy. The proposed method does not require any reference signal, prior information or assumption to extract the BCG artefact. It will be very useful in circumstances where the reference signal is not available. Copyright © 2017 Elsevier B.V. All rights reserved.

    We examined the effect of the selective serotonin 2A (5-HT(2A)) receptor antagonist 7-[4-[2-(4-fluoro-phenyl)-ethyl]-piperazine-1-carbonyl]-1H-indole-3-carbon itrile HCl (EMD 281014) [Bartoszyk, G.D., van Amsterdam, C., Bottcher, H., Seyfried, C.A., 2003. EMD 281014, a new selective serotonin 5-HT2A receptor antagonist. Eur. J. Pharmacol. 473, 229-230.] on change in affect following predator stress. Predator stress involved a 5 min unprotected exposure of rats to a domestic cat. Behavioral effects of stress were evaluated with hole board, plus maze, light/dark box and acoustic startle tests 1 week after stress. Predator stress increased anxiety-like behavior in the plus maze, light/dark box, and elevated response to acoustic startle. EMD 281014 (0.001, 0.01, 0.1, 1 or 10 mg/kg) and vehicle injection (ip) occurred either 10 min after predator stress (prophylactic testing), or 90 min prior to behavioral testing for the effects of predator stress (therapeutic testing 1 week after predator stress). In prophylactic testing, EMD 281014 prevented stress potentiation of startle in a dose dependent manner, though the most effective doses were midrange (0.01 and 0.1 mg/kg). Prophylactic administration of EMD 281014 also prevented stress-induced increase of open arm avoidance in the plus maze in a clear dose dependent manner (from 0.01 mg/kg onward). In therapeutic testing, EMD 281014 had no clear drug dependent effects on stress elevation of startle or on behavior of stressed rats in the elevated plus maze. Finally, EMD 281014 did not block the effects of stress on behavior in the light/dark box when given prophylactically or therapeutically. Findings implicate 5-HT(2A) receptors in initiation of some but not all lasting changes in anxiety-like behavior following predator stress. Potential clinical significance of findings are discussed.

    机载连接词语音识别系统与传统语音识别系统相比,具有背景噪声大,系统识别率要求高等特点.依据这些特点,提出了一种基于经验模态分解增强和位移差分倒谱特征的EMD-SDC连接词语音识别方法.经验模态分解的调频调幅特性,可以有效提高机载复杂噪声背景下的端点检测准确度,位移差分倒谱特征由语音帧的一阶差分谱连接扩展而成,能够更好地提取依赖于语言结构的时序信息.该方法对机载交通预警避撞系统提示语音库进行测试,实验结果表明,采用EMD-SDC方法的机载连接词语音识别系统,能够很好地克服机舱背景噪声干扰,在低信噪比条件下实现较高的识别率.%Compared with traditional speech recognition system, airplane conjunction speech recognition system has background noise, and requires a high recognition rate and so on. According to these features, this paper proposes a EMD-SDC method with empirical mode decomposition and shifted delta cepstral features. Empirical mode decomposition with characteristics of AM FM can substantially increase endpoint detection accuracy under complex airplane noise environment. Shifted delta cepstral which is composed of first-order differential spectral of the speech frames, can capture the time sequence information depending on the structure of the language well. This method is tested for airplane traffic collision avoidance system database, experimental result shows that the airplane conjunction speech recognition system with EMD-SDC method can overcome cabin background noise and achieve a higher recognition rate in the low SNR.

    Elizabeth A Freedman Fowler

    Full Text Available Brachylophosaurini is a clade of hadrosaurine dinosaurs currently known from the Campanian (Late Cretaceous of North America. Its members include: Acristavus gagslarsoni, which lacks a nasal crest; Brachylophosaurus canadensis, which possesses a flat paddle-shaped nasal crest projecting posteriorly over the dorsal skull roof; and Maiasaura peeblesorum, which possesses a dorsally-projecting nasofrontal crest. Acristavus, from the lower Two Medicine Formation of Montana (~81-80 Ma, is hypothesized to be the ancestral member of the clade. Brachylophosaurus specimens are from the middle Oldman Formation of Alberta and equivalent beds in the Judith River Formation of Montana; the upper Oldman Formation is dated 77.8 Ma.A new brachylophosaurin hadrosaur, Probrachylophosaurus bergei (gen. et sp. nov. is described and phylogenetically analyzed based on the skull and postcranium of a large individual from the Judith River Formation of northcentral Montana (79.8-79.5 Ma; the horizon is equivalent to the lower Oldman Formation of Alberta. Cranial morphology of Probrachylophosaurus, most notably the nasal crest, is intermediate between Acristavus and Brachylophosaurus. In Brachylophosaurus, the nasal crest lengthens and flattens ontogenetically, covering the supratemporal fenestrae in large adults. The smaller nasal crest of Probrachylophosaurus is strongly triangular in cross section and only minimally overhangs the supratemporal fenestrae, similar to an ontogenetically earlier stage of Brachylophosaurus. Sutural fusion and tibial osteohistology reveal that the holotype of Probrachylophosaurus was relatively more mature than a similarly large Brachylophosaurus specimen; thus, Probrachylophosaurus is not simply an immature Brachylophosaurus.The small triangular posteriorly oriented nasal crest of Probrachylophosaurus is proposed to represent a transitional nasal morphology between that of a non-crested ancestor such as Acristavus and the large flat

    Full Text Available In order to reduce the noise of a defect electromagnetic signal of the steel cord conveyor belt used in coal mines, a new signal noise reduction method by combined use of the improved threshold wavelet and Empirical Mode Decomposition (EMD is proposed. Firstly, the denoising method based on the improved threshold wavelet is applied to reduce the noise of a defect electromagnetic signal obtained by an electromagnetic testing system. Then, the EMD is used to decompose the denoised signal and then the effective Intrinsic Mode Function (IMF is extracted by the dominant eigenvalue strategy. Finally, the signal reconstruction is carried out by utilizing the obtained IMF. In order to verify the proposed noise reduction method, the experiments are carried out in two cases including the defective joint and steel wire rope break. The experimental results show that the proposed method in this paper obtains the higher Signal to Noise Ratio (SNR for the defect electromagnetic signal noise reduction of steel cord conveyor belts.

    2017-05-01

    The terrestrial Judith River Formation of northern Montana was deposited over an approximately 4 Myr interval during the Campanian (Late Cretaceous). Despite having been prospected and collected continuously by palaeontologists for over a century, few relatively complete dinosaur skeletons have been recovered from this unit to date. Here we describe a new genus and species of ankylosaurine dinosaur, Zuul crurivastator, from the Coal Ridge Member of the Judith River Formation, based on an exceptionally complete and well-preserved skeleton (ROM 75860). This is the first ankylosaurin skeleton known with a complete skull and tail club, and it is the most complete ankylosaurid ever found in North America. The presence of abundant soft tissue preservation across the skeleton, including in situ osteoderms, skin impressions and dark films that probably represent preserved keratin, make this exceptional skeleton an important reference for understanding the evolution of dermal and epidermal structures in this clade. Phylogenetic analysis recovers Zuul as an ankylosaurin ankylosaurid within a clade of Dyoplosaurus and Scolosaurus, with Euoplocephalus being more distantly related within Ankylosaurini. The occurrence of Z. crurivastator from the upper Judith River Formation fills a gap in the ankylosaurine stratigraphic and geographical record in North America, and further highlights that Campanian ankylosaurines were undergoing rapid evolution and stratigraphic succession of taxa as observed for Laramidian ceratopsids, hadrosaurids, pachycephalosaurids and tyrannosaurids.

    Growing evidence indicates that 5-hydrohytryptamine (5-HT) receptors mediate learning and memory. Particularly interesting are 5-HT(6) and 5-HT(7) receptors, which are localized in brain areas involved in memory formation. Interestingly, recently selective 5-HT(6) and 5-HT(7) receptor agonists and antagonists have become available. Previous evidence indicates that 5-HT(6) or 5-HT(7) receptors antagonists had no effects, improved memory formation and/or reversed amnesia. Herein, the effects of EMD (a 5-HT(6) receptor agonist) and AS19 (a 5-HT(7) receptor agonist) in the associative learning task of autoshaping were studied. Post-training systemic administration of EMD (1-10 mg/kg) or AS19 (1-10 mg/kg) were tested in short-term memory (STM) and long-term memory (LTM). Results showed that only EMD 5.0mg/kg impaired both STM and LTM. AS19 at 1-10 mg/kg significantly impaired STM but not LTM. In those groups used to test only LTM, EMD impaired it; while AS19 improved LTM. Moreover, in the interaction experiments, the STM EMD-impairment effect was partially reversed by the selective 5-HT(6) receptor antagonist SB-399885 (10 mg/kg). The STM AS19-impairment effect (5.0 mg/kg) was not altered by the selective 5-HT(1A) antagonist WAY 100635 (0.3 mg/kg) but reversed by the selective 5-HT(7) receptor antagonist SB-269970 (10.0 mg/kg). The AS19-SB-269970 combination impaired LTM. Taken together these data suggest that the stimulation of 5-HT(6) impaired both STM and LTM. 5-HT(7) receptors stimulation impaired STM but improved LTM. And these results are discussed in the context of their possible neural bases.

    2015-07-01

    Full Text Available En el presente artículo se abordan los aportes de Judith Butler en torno al concepto de ciudadanía. Si bien Butler no ha desarrollado una teoría sistemática de la ciudadanía se sostiene que su concepción puede ser reconstruida a partir de su propuesta de ontología social y su interpretación de la contradicción performativa. Para probar esta afirmación, en primer lugar, se realiza dicha reconstrucción. En segundo lugar, se deriva de esta reconstrucción un modo original para pensar el ejercicio de la ciudadanía en los términos de la contradicción performativa. En tercer lugar, se evaluará la conveniencia de este punto de vista para comprender las demandas ciudadanas radicales en la actualidad. Como ejemplo se analizará la demanda de la legalización del aborto en Argentina. En la medida en que esta demanda incluye la realización de abortos medicamentosos, expresa el ejercicio de un derecho que las mujeres aún no poseen legalmente.

    Full Text Available Las autoras de este artículo integramos un proyecto de investigación cuyo objetivo es analizar las articulaciones de subjetividad y agencia que se producen a partir del entramado de los clivajes étnico, de clase, de género y de edad. Partimos de entender que ninguno de estos clivajes opera separado de los demás sino que las subjetividades y las agencias emergen de una trama en la que los posicionamientos que visibilizan alguno de los clivajes implican otros que operan sin ser visibles. Tomamos como instrumentos conceptuales dos propuestas teóricas de Judith Butler. La primera de ellas tiene que ver con el debate en el campo de la teoría feminista por los supuestos etnocéntricos que subyacen al postulado de que la diferencia de género es anterior a otras diferencias y constituye una esfera autónoma de relaciones. La segunda es el uso de la metáfora del travestismo para analizar casos en los que la rearticulación de subjetividad falla en la materialización de la norma que es necesaria para completar la identificación. Con estos instrumentos teóricos analizaremos travestismos de género, clase, edad y etnicidad en Río Negro y Chubut.

    The U.S. Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) are working together to study sea-floor environments off the northeast coast of the United States. During 2008, NOAA survey H11996 collected multibeam echosounder data in a 65-square kilometer area in central Rhode Island Sound, southeast of Point Judith, Rhode Island. During 2010, the USGS collected bottom photographs and sediment samples from 25 stations in this study area. The bathymetry, photography, and sediment data are used to interpret sea-floor features including scour depressions, sand waves, trawl marks, and dredge spoils. Scour depressions cover the bathymetric highs in much of the study area. Sand waves are located mostly in the southwest, and trawl marks tend to be in the northern regions. Dredge spoils are located at a disposal site in a bathymetric low in the western end of the study area. Most stations have a sea-floor surface of sand or silty sand, but eight of the stations have boulders to pea-sized gravel or gravelly sediment on the surface. Photographs show sandy areas typically have scattered burrows, shells, amphipod communities, and worm tubes. Boulders and cobbles are commonly overgrown with hydrozoans and anemones.

    Full Text Available Im neueren Denken Judith Butlers nimmt der Begriff der Vulnerabilität eine Schlüsselrolle ein. Kaum eines der vielen Themen, denen sich die US-amerikanische Autorin seit der Jahrtausendwende widmet, kann ohne Kenntnis ihrer Überlegungen zu diesem Terminus angemessen verstanden werden.

    We examined the effect of the highly selective 5-hydroxytryptamine (5-HT)(2A) receptor antagonist 7-[4-[2-(4-fluoro-phenyl)-ethyl]-piperazine-1-carbonyl]-1H-indole-3-carbonitrile HCl (EMD 281014) in congenital learned helpless male rats in the forced swim test. The administration of EMD-281014 (0.3-30 mg/kg i.p.) to congenital learned helpless rats dose-dependently and significantly (at 10 and 30 mg/kg) decreased immobility and increased swimming compared to vehicle-treated animals. Thus, EMD 281014 produces effects in the forced swim test resembling those of antidepressants.

  18. Joint application of feature extraction based on EMD-AR strategy and multi-class classifier based on LS-SVM in EMG motion classification

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    This paper presents an effective and efficient combination of feature extraction and multi-class classifier for motion classification by analyzing the surface electromyografic (sEMG) signals. In contrast to the existing methods, considering the non-stationary and nonlinear characteristics of EMG signals, to get the more separable feature set, we introduce the empirical mode decomposition (EMD) to decompose the original EMG signals into several intrinsic mode functions (IMFs) and then compute the coefficients of autoregressive models of each IMF to form the feature set. Based on the least squares support vector machines (LS-SVMs), the multi-class classifier is designed and constructed to classify various motions. The results of contrastive experiments showed that the accuracy of motion recognition is improved with the described classification scheme. Furthermore,compared with other classifiers using different features, the excellent performance indicated the potential of the SVM techniques embedding the EMD-AR kernel in motion classification.

    Currently European Union Allowances (EUA) and secondary Certified Emission Reduction (sCER) have become two dominant carbon trading assets for investors and their linkage attracts much attention from academia and practitioners in recent years. Under this circumstance, we use the empirical mode decomposition (EMD) approach to decompose the two carbon futures contract prices and discuss their correlation from the multi-frequency perspective. The empirical results indicate that, first, the EUA and sCER futures price movements can be divided into those triggered by the long-term, medium-term and short-term market impacts. Second, the price movements in the EUA and sCER futures markets are primarily caused by the long-term impact, while the short-term impact can only explain a small fraction. Finally, the long-term (short-term) effect on EUA prices is statistically uncorrelated with the short-term (long-term) effect of sCER prices, and there is a medium or strong lead-and-lag correlation between the EUA and sCER price components with the same time scales. These results may provide some important insights of price forecast and arbitraging activities for carbon futures market investors, analysts and regulators.

    Nowadays, detecting fetal ECG using abdominal signal is a commonly used method, but fetal ECG signal will be affected by maternal ECG. Current FECG extraction algorithms are mainly aiming at multiple channels signal. They often assume there is only one fetus and did not consider multiple births. This paper proposed a single channel blind source separation algorithm to process single abdominal acquired signal. This algorithm decomposed single abdominal signal into multiple intrinsic mode function (IMF) utilizing empirical mode decomposition (EMD). Correlation matrix of IMF was calculated and independent ECG signal number was estimated using eigenvalue method. Nonnegative matrix was constructed according to determined number and decomposed IMF. Separation of MECG and FECG was achieved utilizing nonnegative matrix factorization (NMF). Experiments selected four channels man-made signal and two channels ECG to verify correctness and feasibility of proposed algorithm. Results showed that the proposed algorithm could determine number of independent signal in single acquired signal. FECG could be extracted from single channel observed signal and the algorithm can be used to solve separation of MECG and FECG.

  3. EMD Based Multi-scale Model for High Resolution Image Fusion%基于经验模态分解的高分辨率影像融合

    2008-01-01

    High resolution image fusion is a significant focus in the field of image processing. A new image fusion model is presented based on the characteristic level of empirical mode decomposition (EMD). The intensity hue saturation (IHS) trans- form of the multi-spectral image first gives the intensity image. Thereafter, the 2D EMD in terms of row-column extension of the 1D EMD model is used to decompose the detailed scale image and coarse scale image from the high-resolution band image and the intensity image. Finally, a fused intensity image is obtained by reconstruction with high frequency of the high-resolution image and low frequency of the intensity image and IHS inverse transform result in the fused image. After pre- senting the EMD principle, a multi-scale decomposition and reconstruction algorithm of 2D EMD is defined and a fusion tech- nique scheme is advanced based on EMD. Panchromatic band and multi-spectral band 3,2,1 of Quickbird are used to assess the quality of the fusion algorithm. After selecting the appropriate intrinsic mode function (IMF) for the merger on the basis of EMD analysis on specific row (column) pixel gray value series, the fusion scheme gives a fused image, which is compared with generally used fusion algorithms (wavelet, IHS, Brovey). The objectives of image fusion include enhancing the visibility of the image and improving the spatial resolution and the spectral information of the original images. To assess quality of an image after fusion, information entropy and standard deviation are applied to assess spatial details of the fused images and correlation coefficient, bias index and warping degree for measuring distortion between the original image and fused image in terms of spectral information. For the proposed fusion algorithm, better results are obtained when EMD algorithm is used to perform the fusion experience.

    The chlorophyll is the main pigment for the photosynthesis of crops. The BPNN is a novel method of inver-sing chlorophyll content. In order to study chlorophyll content inversion model with higher precision, it was used to increase the correlation between input factors and chlorophyll content by combining empirical mode decomposition (EMD) with spectral derivative (SD). And genetic algorithm(GA) was used to optimize BPNN building GA-BP model to get the best initial weights and thresholds. The spectral reflectance of corn leaf was pretreated by the meth-ods of EMD and derivative, getting the EMD-SD spectrum. It was selected as the input factors of GA-BP model that the EMD-SD values in five bands whose correlation coefficients with chlorophyll content were over 0. 6. Then the GA-BP model with seven hidden layer nodes was established, selecting the network whose fitness of the best individual was the lowest to predict the chlorophyll content of corn leaf. R2 of GA-BP model was the highest, at 0. 818, RMSE was 2. 442 and e was 5. 436%. The results showed that the predicting precision of GA-BP model using EMD-SD val-ues as input factors was higher than MLR and BP model. It was verified feasible that using GA-BP model based on EMD-SD spectrum to improve the inversion accuracy of corn leaf chlorophyll content.%叶绿素是作物进行光合作用所需的主要色素,BP神经网络( BPNN)是较为新颖的反演叶绿素含量的方法。为研究反演精度更高的叶绿素含量反演模型,将经验模态分解( EMD)与光谱微分( SD)结合来提高输入因子与叶绿素含量的相关性,并使用遗传算法( GA)优化BPNN得到GA-BP模型以获得最优初始权值阈值。将光谱数据EMD后进行一阶微分变换得到EMD-SD光谱,选择与叶绿素含量相关系数超过0.6的5个波段处的EMD-SD值作为GA-BP模型的输入因子,隐含层节点数为7,多次训练取最优个体适应度值最低的GA-BP模型来反演

    Full Text Available El enfoque interpretativo de la visión social de la bibliotecóloga mexicana Judith Licea se articuló en tres esferas: 1. bibliotecas y sociedad excluyente, 2. bibliotecas y sociedad incluyente, 3. bibliotecas y sociedad plural. Mediante dos esquemas que van de lo general a lo particular, se configuró el pensamiento de Judith Licea en torno a esas tres dimensiones. Este análisis concluye que la óptica social bibliotecológica de la autora hace posible tejer una serie de categorías asociadas a lo que hoy se denomina bibliotecología social; asimismo, que la idea homogénea en la esfera de la gestión de servicios bibliotecarios y de información debe quedar atrás para dar paso a la idea diferenciada. También se desprende del estudio que los profesionales de la biblioteca tienen un gran reto en los procesos formales, informales y continuos de enseñanza-aprendizaje.

    Electroencephalographic (EEG) recordings are often contaminated with muscle artifacts. This disturbing myogenic activity not only strongly affects the visual analysis of EEG, but also most surely impairs the results of EEG signal processing tools such as source localization. This article focuses on the particular context of the contamination epileptic signals (interictal spikes) by muscle artifact, as EEG is a key diagnosis tool for this pathology. In this context, our aim was to compare the ability of two stochastic approaches of blind source separation, namely independent component analysis (ICA) and canonical correlation analysis (CCA), and of two deterministic approaches namely empirical mode decomposition (EMD) and wavelet transform (WT) to remove muscle artifacts from EEG signals. To quantitatively compare the performance of these four algorithms, epileptic spike-like EEG signals were simulated from two different source configurations and artificially contaminated with different levels of real EEG-recorded myogenic activity. The efficiency of CCA, ICA, EMD, and WT to correct the muscular artifact was evaluated both by calculating the normalized mean-squared error between denoised and original signals and by comparing the results of source localization obtained from artifact-free as well as noisy signals, before and after artifact correction. Tests on real data recorded in an epileptic patient are also presented. The results obtained in the context of simulations and real data show that EMD outperformed the three other algorithms for the denoising of data highly contaminated by muscular activity. For less noisy data, and when spikes arose from a single cortical source, the myogenic artifact was best corrected with CCA and ICA. Otherwise when spikes originated from two distinct sources, either EMD or ICA offered the most reliable denoising result for highly noisy data, while WT offered the better denoising result for less noisy data. These results suggest that

    Speech signal is corrupted inevitably by noise which results in speech distortion during generation, transmission and reception process. In this paper, Empirical Mode Decomposition (EMD) for non -stationary and nonlinear signal analysis is applied to speech de - noising. Moreover, focusing on the problems of envelopes fitting and interpolation selection in conventional EMD, an improved EMD is proposed, which uses cubic Hermite interpola-tion instead of cubic spline for signal envelopes fitting, and doubly - iterative sifting method instead of local extrema for interpolation points selection. Thus, the errors of algorithm can be reduced, and overshoots or undershoots be a-voided. Simulation shows that the proposed method decreases speech distortion and increases output SNR, compared with speech de - noising based on wavelet and conventional EMD.%语音信号在产生、传输及接收过程中,不可避免会受到噪声干扰从而引起失真.针对传统经验模态分解算法存在的包络线拟合和插值点选择问题,为减少语音失真,提高语音质量,提出了一种改进的经验模态分解算法.采用分段三次埃尔米特插值代替三次样条来计算信号包络,并结合内、外双迭代法代替局部极值来求插值点,从而降低了算法的分解误差,避免了拟合时的过冲欠冲现象.仿真结果表明,与小波变换和传统经验模态分解的语音去噪相比,提出的算法减少了语音的失真,提高了输出信噪比.

    Using a large set of ultrasound features does not necessarily ensure improved quantitative classification of breast tumors; rather, it often degrades the performance of a classifier. In this paper, we propose an effective feature reduction approach in the transform domain for improved multi-class classification of breast tumors. Feature transformation methods, such as empirical mode decomposition (EMD) and discrete wavelet transform (DWT), followed by a filter- or wrapper-based subset selection scheme are used to extract a set of non-redundant and more potential transform domain features through decorrelation of an optimally ordered sequence of N ultrasonic bi-modal (i.e., quantitative ultrasound and elastography) features. The proposed transform domain bi-modal reduced feature set with different conventional classifiers will classify 201 breast tumors into benign-malignant as well as BI-RADS⩽3, 4, and 5 categories. For the latter case, an inadmissible error probability is defined for the subset selection using a wrapper/filter. The classifiers use train truth from histopathology/cytology for binary (i.e., benign-malignant) separation of tumors and then bi-modal BI-RADS scores from the radiologists for separating malignant tumors into BI-RADS category 4 and 5. A comparative performance analysis of several widely used conventional classifiers is also presented to assess their efficacy for the proposed transform domain reduced feature set for classification of breast tumors. The results show that our transform domain bimodal reduced feature set achieves improvement of 5.35%, 3.45%, and 3.98%, respectively, in sensitivity, specificity, and accuracy as compared to that of the original domain optimal feature set for benign-malignant classification of breast tumors. In quantitative classification of breast tumors into BI-RADS categories⩽3, 4, and 5, the proposed transform domain reduced feature set attains improvement of 3.49%, 9.07%, and 3.06%, respectively, in

    针对EMD(Empirical Model Decomposition)存在模式频率混叠带来的频谱杂乱的根本缺陷,提出一种高速列车万向轴动不平衡动态检测的新方法。该方法的核心是:对万向节安装机座的振动信号进行 EMD 分解得到基本模式分量,应用基本模式分量信号来构造 Hankel 矩阵,对该矩阵进行奇异值正交化分解,以奇异值关键叠层作为奇异值的选择准则对信号进行重构,应用重构信号的傅里叶谱来检测高速列车万向轴的动不平衡,消除 EMD 分解模式频率混叠带来频谱杂乱,提高了谱的清晰度,凸显了故障特征。应用万向轴动不平衡试验数据对该方法进行试验验证,结果表明:该方法能够有效检测万向轴动不平衡引起故障特征和万向轴的固有振动特性,与纯 EMD 方法相比,该方法在谱的清晰度和故障表征力上得到了显著提高。%A new method of detecting dynamic imbalance due to cardan shaft in high-speed train was proposed applying a synthesized method of EMD (Empirical Modal Decomposition),Hankel matrix and SVD (singular value decomposition)against the aliasing defect between adjacent intrinsic model functions existing in EMD.The vibration signals of gimbal installed base were decomposed through EMD to get the different intrinsic model components.The Hankel matrix,constructed of the single decomposition model components,was orthogonally decomposed through SVD and the key singular values were selected to reconstruct the vibration signal on the base of the key stack of singular values.The Fourier spectrum of the reconstructed signal was applied to detect dynamic imbalance of shaft and the clutter spectrum caused by the aliasing defect between adjacent intrinsic model functions was eliminated so as to highlight the failure characteristics.The method was verified by test data in the condition of dynamic imbalance.The results show the method can effectively detect the

    2012-01-01

    In order to improve the noise reduction effect of the control system, an active noise control system based on EMD(empirical mode decomposition) and loudness is proposed. The noise source is decomposed adaptively using EMD at first and the loudness of all IMFs is calculated in such a system. Then a shaping filter of the error signal is designed according to the amplitudes of the IMF loudness. The filter designed with this method can restrain the components of noise source with small loudness better than A-weighting shaping filter. The noise reduction effect of the active noise control system is simulated. The results show that the control system proposed in this paper can improve the noise reduction effect compared with the system based on filtered-X LMS (filtered-X least mean square) and A-weighting shaping filter.%为了提高有源噪声控制系统的降噪效果,提出了基于经验模态分解( empirical mode decomposition,EMD)和响度的控制系统.该系统首先采用EMD方法对噪声源进行自适应分解,并对分解后的各个固有模态函数(intrinsic mode function,IMF)分量的响度进行计算,然后根据各个分量的响度大小进行残差滤波器的设计.与基于A计权曲线设计的残差滤波器相比,该方法所设计滤波器能更好地抑制响度较小的信号频率成分.对有源噪声控制系统的降噪效果进行了仿真,结果表明,所提出的控制系统比传统滤波-X LMS(filtered-X least mean square)方法和采用基于A计权残差滤波器的系统降噪效果更好.

  6. The fragility of identity: about the internal experience of gender in Law N° 26.743 Reflections from Pierre Bourdieu and Judith Butler

    2014-12-01

    Full Text Available The following article intends to approach some aspects of bourdiean thoughts in order to develop an approach to the notion of gender and the way in which – within an androcentric symbolic order and a normative heterosexual matrix – function these diagrams in the way gender makes up the subjective corporal form. From those notions, we want to reflect about the emergency of sexual identities that transgress the cultural precepts around gender founded in doxic experience. Likewise, we will sketch a brief reference among inconscient dimension across psychoanalytical tradition and performative theory across Judith Butler in the feminists debates.Through this conceptual framework we will attempt to examine how may the dominant representations of femininity, androcentric and heterosexually regulated, influence the identity formation of a feminine transsexual person, founded in the morphological ideal which has sustenance in the man-woman dichotomy, leaving the questioning open about the ways that the transgressive assumption of sex of what appears like the order of things may take in a binomic gender matrix, examining the reception of this debates in te Gender Identity Law N° 26.743

    Full Text Available El presente trabajo rescata una de las líneas teóricas puestas en consideración en la mesa temática Problemas de Género durante el 9º Congreso Argentino y 4ºLatinoamericano de Educación Física y Ciencias. A partir de aquellos trabajos que referenciaron a Judith Butler en sus desarrollos, con el fin de cuestionar los criterios naturalizados con los que se clasifican los cuerpos, se intentan ampliar y profundizar las reflexiones de algunos expositores. Para tal fin, se exponen los interrogantes que emergieron en el interior de los debates sobre este punto, al tiempo que se enfatizan las líneas argumentativas utilizadas en algunas de las ponencias que dan cuenta de modos alternativos de pensar al cuerpo más allá de explicaciones esencialistas. Finalmente, se retoman algunas reflexiones llevadas a cabo en el debate posterior a la lectura de los trabajos que focalizaron el lugar de las prácticas de la educación física como reproductora y transformadora, al mismo tiempo, de las normas de género y sexualidad

  8. The pendulum is never static: Jesus Sira to Jesus Christ on women in the light of Judith, Susanna and LXX Esther

    Directory of Open Access Journals (Sweden)

    Pierre Jordaan

    2009-09-01

    Full Text Available When the New Testament is interpreted, directly preceding literature is largely neglected. The dialectical terms, discourse and contra-discourse do not often surface in research on this period. This is especially the case with reference to women. Jesus Ben Sira (ca. 196 BCE as well as other wisdom writers had quite a negative view of women. Although it has previously been argued that this negative discourse on women was challenged by Judith, this article goes further: the Additions to Esther and Susanna are added as possible challenging discourses. It is argued that these texts convincingly confront Ben Sira’s negative views and add substantial value to the worth and status of women. During the CE, both Jesus Christ and the Apostle Paul had a mainly positive view of women. Positive ideas and allusions from texts are pointed out that might have their roots in the Apocrypha. Lastly, this article argues that the disputed Pauline letters contain a swing back towards Jesus Ben Sira’s negative view of women.

    The existing methods ignore multicomponent characteristics of evolution process of Internet public opinions, which leads to an unsatisfactory performance of analysis and modeling. To deal with the problem, this paper presents an evolution analysis and modeling method of Internet public opinions based on Empirical Mode Decomposition(EMD). It decomposes the evolution process of Internet public opinions by EMD, to form trend component, period component, mutation component and random component. Then it analyzes and models the evolution process of Internet public op.nions by analyzing and modeling the above-mentioned components. Experiments show that the components decomposed by EMD have clear physical meanings, which can help to analyze the evolution patterns of Internet public opinions; at the same time, the method has good forecasting performance, thus is more suitable.%现有研究忽略网络舆情演化过程的多成分特性,导致演化分析与建模效果较差.为此,提出一种基于经验模态分解(EMD)的网络舆情演化分析与建模方法.对演化过程进行EMD分解,形成演化过程的趋势成分、周期成分、突发成分和随机成分,通过对各成分进行分析与建模,实现网络舆情的演化分析与建模.实验结果表明,该方法通过EMD分解得到的各成分物理含义明显,有助于分析网络舆情的演化规律,同时具有较好的趋势预测效果,适合进行演化建模.

    经验模态分解(EMD)及局域均值分解(LMD)都是转子故障诊断领域时频分析的有效方法.EMD为非平稳信号进行有意义的Hilbert变换起到了桥梁的作用,但是却会因此而产生了不能解释的负频率.而LMD将一个复杂的多分量信号分解为若干个瞬时频率有物理意义的乘积函数(Production Function PF),并且其局部均值函数与包络估计函数都是采用平滑处理的方法形成的避免了EMD方法中的过包络与欠包络现象.实验通过采用LMD与EMD方法对两类常见的转子故障信号的分析比对,得出LMD在高频和频率变化波动大的故障信号中比EMD效果更佳明显.

    2015-08-01

    Full Text Available Seizure detection using brain signal (EEG analysis is the important clinical methods in drug therapy and the decisions before brain surgery. In this paper, after signal conditioning using suitable filtering, the Gamma frequency band has been extracted and the other brain rhythms, ambient noises and the other bio-signal are canceled. Then, the wavelet transform of brain signal and the map of wavelet transform in multi levels are computed. By dividing the color map to different epochs, the histogram of each sub-image is obtained and the statistics of it based on statistical momentums and Negentropy values are calculated. Statistical feature vector using Principle Component Analysis (PCA is reduced to one dimension. By EMD algorithm and sifting procedure for analyzing the data by Intrinsic Mode Function (IMF and computing the residues of brain signal using spectrum of Hilbert transform and Hilbert – Huang spectrum forming, one spatial feature based on the Euclidian distance for signal classification is obtained. By K-Nearest Neighbor (KNN classifier and by considering the optimal neighbor parameter, EEG signals are classified in two classes, seizure and non-seizure signal, with the rate of accuracy 76.54% and with variance of error 0.3685 in the different tests.

    2009-01-01

    This article analysed the different narratives implied in Philemon by utilising the narrative therapeutic approach, as developed by Epston and White (1990). A dominant narrative (the harsh treatment of slaves in the early Christian environment) and a challenging narrative (a more humane conduct of slaves) were clearly distinguished. The article showed Paul’s attempt to bridge the gap between these two narratives by using certain pointers, possibly taken from mystery religions and Jesus’ examp...

    In order to suppress the cross term interference in the Cohen-class quadratic time-frequency distribution, a method was proposed based on empirical mode decomposition (EMD) and Choi-Williams distribution. In this method, several intrinsic mode functions (IMFs) of the signals were separated from the frequency domain by using EMD. The time-frequency transformation of Cohen-class distribution was carried out after deleting the false components generated by EMD, and then the Cohen-class time-frequency distribution of original signal was reconstructed by means of linear superposition of the IMFs Cohen-class distribution results. Simulation results showed that the method could be used to suppress effectively the cross terms of Cohen-class distribution, ensure Cohen-class distribution time-frequency concentration, and extract disturbance features.%针对Cohen类二次型时频分布存在的交叉项,提出一种基于EMD与Choi-Williams分布相结合的方法,利用经验模态分解将信号从频域上分离若干个固有模态函数经过去伪后进行Cohen分布的时频变换,将得到的结果叠加重构出原始信号的Cohen类时频分布.仿真结果表明,该方法能有效抑制时频分布的交叉项,保证Cohen分布的时频聚集性,提取扰动特征.

Methods Nine patients were treated with 4 mg/m2 per day of EMD 273063 given as a 4-h intravenous infusion on days 1, 2, and 3 every four weeks (one cycle. Peripheral blood was analyzed for T cell and natural killer cell phenotype and frequency, as well as levels of soluble IL2 receptor (sIL2R, IL10, IL6, tumor necrosis factor alpha and neopterin. Biopsies of tumor metastasis were performed prior to therapy and at day 10 of the first 2 cycles to study lymphocyte accumulation by immunohistochemistry. Results Treatment was generally well tolerated and there were no study drug-related grade 4 adverse events. Grade 3 events were mainly those associated with IL2, most commonly rigors (3 patients and pyrexia (2 patients. Best response on therapy was stable disease in 2 patients. There were no objective tumor regressions by standard response criteria. Systemic immune activation was demonstrated by increases in serum levels of sIL2R, IL10, and neopterin. There was evidence of increased tumor infiltration by T cells, but not NK cells, in most post-dosing biopsies, suggesting recruitment of immune cells to the tumor site. Conclusion EMD 273063 demonstrated biologic activity with increased immune-related cytokines and intratumoral changes in some patients consistent with the suspected mechanism of action of this immunocytokine.

First, EMD method was employed to decompose the signal into a group of IMFs according to their frequencies. The IMF with bigger energy power was chosen as the useful component. Then third-order cumulant was used to depress the white Gaussian noise and the short-time estimation of third-order cumulant diagonal slice can be received during the process. A detection function which is based on short-time estimation and its envelope were recognized as the detection statistic to determine whether there are transient signals. At last, simulated data were used to test the effect of the method. The results illustrate that the detection method based on EMD and third-order cumulant can detect the underwater acoustic transient signals at lower SNRs, which is very valuable in the engineering application.

    The electrolytic manganese dioxide (EMD) production in using graphite or copper hydrogen evolution cathode is high energy consumption, pollution and risks. To keep anodic reaction unchanged, a theoretically cell voltage cut of 1. 229 V can be obtained through the introduction of the electrolysis cell based on a gas diffusion cathode (GDE) of the green oxygen reduction reaction. Meanwhile, the acid mist will be reduced on the cathode. Studying the new synthetic method of EMD in using oxygen cathode for energy saving and environment friendly, it is confirmed that the cell voltage and energy consumption of new method by using GDE ( Pt/C type) will be 1/3 ~ 1/2 of that by using Cu and Pt cathode, compared with the traditional Cu and Pt hydrogen evolution cathode, at the current density of 20 ~ 140 A o m-2. XRD analysis shows that the anodic deposition of the powder belongs to γ -MnO2.

Will untersucht außerdem eine Reihe von Reformansätzen und Lösungsmodellen, mit welchen den bestehenden Defiziten begegnet werden soll, und neigt dabei zu einer Lösung, welche auf den Ausbau von Dienstleistungen für Familien setzt, z. B. durch Ausbau und qualitative Verbesserung öffentlicher Kinderbetreuung in Kindergärten, Krippen und Horten. Dies trage auch zu verbesserten Erwerbschancen für Frauen sowie zur Vermeidung von Familienarmut bei.In her very well structured work of social justice on the existing benefits intended to support families as well as those to be created in the future, Judith Will offers a comprehensive and (for the most part complete overview of all the essential social benefits needed for family support. Will examines, moreover, a series of proposals for reform and solution models, with which the existing deficits should be approached. She leans toward a solution that banks on the expansion of family services, for example through the qualitative improvement of public childcare in kindergartens, day cares, and after school care. This would also significantly better the earning chances for women and help to avoid family poverty.

As the signals are often corrupted by noise, so they are de-noised, and preprocessed signals are investigated using ANFIS analysis. The results show that the wavelet packet de-noising based on EMD can improve the Signal-to-Noise Ratio(SNR)effectively. After signals are preprocessed, the result of ANFIS analysis shows that average error is low. It can diagnose the three fault types above-mentioned better.

  8. ¿Por qué le llaman género cuando quieren decir sexo? Una aproximación a la teoría de la performatividad de Judith Butler

    Full Text Available Este artículo pretende constituir una aproximación desde la Psicología Social a la teoría de la performatividad de género de Judith Butler. Si bien dentro del pensamiento feminista contemporáneo se ha venido asociando la categoría "sexo" al ámbito de lo natural y la categoría "género" a la dimensión cultural y socialmente construida de las categorías asociadas al sexo (siendo presentados ambos términos como un par de opuestos, Butler efectúa en su obra una deconstrucción de dicha dicotomía, mostrando como el sexo es ya de por sí una construcción social que, por tanto, ha sido género todo el tiempo. En este texto también se intenta indagar en la aportación que la teoría de performatividad puede suponer para una teoría de la subjetividad en psicología social; para ello resulta fundamental la defensa que Butler hace de la aparentemente paradójica posibilidad de transformación social a partir de las categorías sociales que, a la vez que nos conforman como sujetos, nos están subordinando.

    To solve the problems of automatic fault diagnosis of rotating machinery, an intelligent method based on EMD and MLEM2 was presented. EMD was used to preprocess the original vibration signal, after that, six time-domain characteristic indices and five frequency-domain indices were calculated on the most appropriate IMF to form the dimensionless fault eigenvector of rolling bearings. According to the characteristic vector, fault decision table could be acquired by the data collected from the running machine. The MLEM2 algorithm was then applied to mine diagnostic rules from the data table. By these rules and an improved rule matching strategy, the final fault classification was carried out. EMD could discover the fault essence of the signal, and enhance the signal-to-noise rate of the selected IMF, while MLEM2 algorithm could be operated without attribute discretization, so the result rules were more complete and accurate. It was proved by the experiment of SKF6203 rolling bearings that the accuracy of this method reached 93.75%.It works like an expert system with the ability of acquiring knowledge itself, and does not need any artificial interference once the initialization is made. It is a valid method for intelligent fault diagnosis of rolling bearings.%针对旋转机械的自主故障诊断,提出一种基于EMD和MLEM2的智能解决方法.利用EMD预处理振动信号,在最适合的IMF分量上提取6个时域指标和5个频域指标构成无量纲的轴承故障特征向量.根据设备运行数据形成决策表,使用改进的MLEM2算法挖掘诊断规则,再结合改进的规则匹配策略进行状态识别.EMD能够剥离故障最本质的信息,提高所选分量的信噪比,而MLEM2算法无需对连续属性事先离散化,获得的诊断规则更完备、准确.SKF6203轴承试验表明,该方法诊断精度达到93.75%,相当于能够自主获取知识的专家系统,且只要一次初始设定,无需后续人工干预,是一种有效的智能诊断方法.

    Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used to determine rare earth element (REE) content of 76 fossil bones collected from the Upper Cretaceous (Campanian) Two Medicine (TMF) and Judith River (JRF) Formations of Montana. REE content is distinctive at the formation scale, with TMF samples exhibiting generally higher overall REE content and greater variability in REE enrichment than JRF samples. Moreover, JRF bones exhibit relative enrichment in heavy REE, whereas TMF bones span heavy and light enrichment fields in roughly equal proportions. TMF bones are also characterized by more negative Ce anomalies and greater U enrichment than JRF bones, which is consistent with more oxidizing diagenetic conditions in the TMF. Bonebeds in both formations show general consistency in REE content, with no indication of spatial or temporal mixing within sites. Previous studies, however, suggest that the bonebeds in question are attritional assemblages that accumulated over considerable time spans. The absence of geochemical evidence for mixing is consistent with diagenesis transpiring in settings that remained chemically and hydrologically stable during recrystallization. Lithology-related patterns in REE content were also compared, and TMF bones recovered from fluvial sandstones show relative enrichment in heavy REE when compared with bones recovered from fine-grained floodplain deposits. In contrast, JRF bones, regardless of lithologic context (sandstone versus mudstone), exhibit similar patterns of REE uptake. This result is consistent with previous reconstructions that suggest that channel-hosted microfossil bonebeds of the JRF developed via the reworking of preexisting concentrations embedded in the interfluve. Geochemical data further indicate that reworked elements were potentially delivered to channels in a recrystallized condition, which is consistent with rapid adsorption of REE postmortem.

    In recent years, extreme weather events have caused the widespread concern of the Whole world,but sustained extreme temperature events have been seldom researched up to now.The extreme threshold of temperature is defined in this paper by the percentile value of time series of daily maximum or minimum temperature,and the annual frequency of sustained(greater than two successive days)ex-treme high(FSEHT)and low temperature(FSELT)events during 1971-2005 in Yuncheng are alia.1yzed with the improved Empirical Mode Decomposition(EMD)method presented by Deering.The re-suits show that during the 35 years,the FSEHT and FSELT series both exhibit a linear decreasing trend in Yuncheng;the negative linear correlation between the FSELT series and the annual mean temperature series is statistically significant at the 0.05 confidence level, while changes in FSEHT are almost not af-fected by the annual mean temperature. Besides there are also oscillations of different periods in the two frequency series;and in view of principle periods,the oscillations of the two series are consistent with those of El Nino events.%采用每日最高(最低)气温的历史同期序列的分位数作为该日的极端阈值,运用改进的经验模态分解(empirical mode decomposition,EMD)方法对山西省运城市1971-2005年每年发生的持续(3 d及3 d以上)极端气温频数进行了初步分析.结果表明,1971-2005年运城市每年的持续极端高温频数(frequency of sustained extreme-high temperature,FSEHT)和持续极端低温频数(fre-quency of sustained extreme-low temperature,FSELT)序列均存在线性下降趋势;在0.05的水平下, 运城市的FSEHT序列与该地区的年平均气温序列的线性相关性不显著,而该地区的FSELT序列与年平均气温序列的负线性相关关系是显著的;此外,这两个频数序列分别存在不同的周期振荡.从主要周期看,运城市的FSEHT和FSELT序列与厄尔尼诺现象的周期相一致.

    2016-01-01

    Through the analysis of the theory of Hegel, Nietzsche, Freud and Althusser, Judith But-ler points out a way of theoretical reflection on subjective self-sufficiency. The subject may submit to pow-er, while taking shape and acquiring dynamism at the same time. For Butler, to theorize subjection re-quires a psychoanalytic theory of the constitution of the subject. The spiritual world of the subject is de-termined by the power operation of the social world. But identification of the subject to power may not al-ways be realized, which implies some kind of resistance. In a sense, Butler’s research is not traditional e-mancipatory politics but the politics of recognition.%美国著名哲学家朱迪斯·巴特勒通过对黑格尔、尼采、弗洛伊德和阿尔都塞的理论的分析,指认出一条反思主体自足性的理论路径,其表明个体对权力的服从既是向权力屈从的过程,同时也是主体得以形成并获得能动性的条件。巴特勒试图从精神分析的角度去探究主体在精神方面获得建构的过程,指出主体的精神世界是由社会世界的权力运作决定的,自我在形成过程中内化了特定的社会规训。但主体对权力的认同未必总能实现,其中蕴含着某种反抗的可能。可以说,巴特勒的研究不再是传统意义上的解放政治,而是一种承认的政治、服从的政治。

    针对风电场并网点电压故障引起的风机大规模脱网问题,提出了基于柔性形态算子和经验模态分解(empirical mode decomposition,EMD)去噪技术的电网电压故障检测方法。首先,利用EMD对采样信号进行时频自适应预处理,从而确定噪声主导模态;然后,通过柔性形态学变换加阈值输出,有效放大信号奇异点,避免了因电网电压信号周期性变化和噪声引起的背景梯度对检测结果的影响,实现故障定位检测。通过对不同噪声强度的电压暂降故障信号进行检测对比分析发现,随着信号信噪比下降,标准形态学方法的检测误差进一步增大,当信噪比达到25db时,甚至出现了误检现象,而柔性形态EMD检测方法仍然可以有效检测故障扰动的起止时间,表明该方法与标准形态学和小波阈值方法相比,在简化运算过程的同时可以获得更高的检测精度。最后,对某风电场并网点故障电压的分析结果与实测数据的一致性,验证了该方法可以有效检测电网电压的瞬态故障信息,从而为风电场无功补偿装置的投切控制提供了依据。%As the penetration of wind power has become significant, one of the important challenges of power distribution network with wind power integration is the risk of large-scale wind turbine tripping accidents caused by over/under voltage faults in farms and systems, which also leads to unexpected variations in frequency parameters and thereby power quality issues.

    A wind power prediction method based on empirical mode decomposition(EMD) and support vector machine(SVM) is proposed to treat with the nonlinearity and nonstationarity of wind speed data.Firstly,the wind speed data is decomposed into a series of components with stationarity by using EMD to reduce the influence between different feature information.Then,different models were built and different kernel functions and parameters were chosen to deal with each group of data by using SVM in order to improve the forecasting accuracy.Finally,short term wind power forecasting was made based on wind speed data through a practical wind power curve.Case study was carried out to investigate the validity of the novel algorithm and the results illustrated that the forecasting error of EMD-SVM combined model decreased by 5%~10% compared to single statistics model.The proposed combined model can improve the short term forecasting accuracy of wind power effectively by tracking the change of wind power.%针对风速序列随时间、空间呈现非平稳性变化的特征,提出一种基于经验模态分解(empirical mode decomposition,EMD)和支持向量机(support vector machine,SVM)的EMD-SVM短期风电功率组合预测方法。该方法首先利用EMD将风速序列分解为一系列相对平稳的分量,以减少不同特征信息间的相互影响;然后利用SVM法对各分量建立预测模型,针对各序列自身特点选择不同的核函数和相关参数来处理各组不同数据,以提高单个模型预测精度。最后将风速预测结果叠加并输入功率转化曲线以得到风电功率预测结果。研究结果表明,EMD-SVM组合预测模型能更好地跟踪风电功率的变化,其预测误差比单一统计模型降低了5%~10%,有效地提高了短期风电功率预测的精度。

    In order to extract dynamic characteristics of vehicle-track coupling system, the method of improved empirical mode decomposition (IEMD) was presented. In the method, the field mean of extrema was adopted instead of the points envelope mean and the boundary wave matching algorithm was used to restrain the end effect. Based on the theory of vehicle-track coupling dynamics, the vehicle ballastless-track vertically coupling dynamics model was established. With the rail corrugation and rail irregularity excitation model, dynamic responses of vehicle-track coupling system were calculated at different driving speed. The dynamic responses were decomposed by IEMD, and then the intrinsic mode functions of vertical contact force, bogie acceleration, and car body acceleration were analyzed and compared. The results show: the IEMD can self-adaptively decompose vibration signals to intrinsic mode functions and so effectively extract dynamic characteristics of vehicle-track coupling system.%提出利用一种改进的经验模态分解(EMD)方法提取车辆-轨道耦合系统的动力学特性.该方法以改进的极值域均值代替极值点包络线的均值来提高局部均值的求解精度,以边界波形匹配预测法来抑制端点效应.基于车辆-轨道耦合动力学理论,建立客车-弹性支承块无砟轨道垂向耦合动力学模型,计算车辆-轨道耦合系统在波浪形磨损和轨道不平顺组合激励模型下的振动响应.运用改进的EMD方法对系统的振动响应进行经验模态分解,并且对轮轨力、转向架和车体加速度的本征函数进行分析和比较.研究结果表明:改进的EMD方法自适应地将振动响应分解成本征函数,能有效地提取车辆-轨道耦合系统的动力学特性.

The original AE signals were decomposed by EMD, and the intrinsic mode function (IMF) including the main feature information was selected. The energy ratios of IMF were constructed as a feature vector to identify the type of damage signals. BP neutral network pattern classifier was then established to identify four types of plywood damage signals. The measured result from a five-layed plywood damage shows that the method can extract AE signals characteristics precisely and identify damage types efficiently.

    In Bodies that Matter,Judith Butler examed the material dimensions of the construction of "sex" and "body",which continued the topic of performative theory in the last book Gender Trouble.Initially,she used the power theory of Foucault to sketch the body's topography of construction.Consequently,the assumption of sex was phantasmatic identification within the psychoanalysis,although Freud and Lacan was phallocentrism.In the end,through a critical engagement with Slavoj Zizek's performative theory of names,Butler provided the resignification function of names could show us the agency of subject.%《身体之重》是美国学者朱迪斯.巴特勒继提出性别述行理论的成名作《性别麻烦》之后,继续探讨生理性别与身体在物质维度上如何述行建构这一问题的力作。一方面,她借助米歇尔.福柯的权力话语理论,对身体的物质性建构进行了考察;另一方面,她力图在精神分析理论的菲勒斯中心主义框架内揭示性别认同的幻象。通过批判齐泽克的称谓述行理论,巴特勒提出称谓的再赋义功能,认为主体在话语的掌控当中依然具有能动性。

    经典的经验模式分解(EMD)方法通过求解信号的上下2条三次样条包络曲线的均值曲线,实现对原始信号的分解.但是对于非平稳、非线性信号,包络平均无法代替真正的局部平均.另外,基于包络平均的分解方法还会引入极值过冲和欠冲问题.利用B样条的良好局部性质直接计算信号的局部均值插值曲线,克服了三次样条包络方法在EMD分解中的不足.通过对旋转机械故障振动信号的分解处理,表明基于B样条局部均值插值曲线的经验模式分解方法得到的固有模式函数更符合信号的真实物理意义,分解结果更好.

    Herring (Clupea harengus pallasi) spawning sites in Puget Sound, Washington overlap spatially and temporally with blooms of Alexandrium catenella, a toxic dinoflagellate species responsible for paralytic shellfish poisoning. Consequently, newly hatched herring larvae may be regularly exposed to the suite of dissolved paralytic shellfish toxins that are released into the water column from toxic cells during blooms. To date, virtually nothing is known about the impacts of these neurotoxins on early developmental stages of marine fish. In the present study, herring larvae at three ages, 0 days post hatch (dph), 4 dph, and 11 dph, were exposed to dissolved saxitoxin (STX) in 24-h and multi-day exposures. All larvae were examined for sensorimotor function (i.e. spontaneous swimming behavior and touch response). Significant reductions in spontaneous and touch-activated swimming behavior occurred within 1 h of exposure. EC50s at 1 h of exposure were 1,500, 840, and 700 μg STX equiv. l−1 for larvae introduced to STX at 0, 4, and 11 dph, respectively. This progressive age-specific increase in STX-induced paralysis suggests that older larvae were more sensitive to the toxin than younger larvae. Interestingly, herring larvae at all ages exhibited a significant degree of neurobehavioral recovery within 4–24 h of continuous exposure relative to the 1-h time point. This recovery of normal motor behaviors was not observed in previous studies with freshwater zebrafish (Danio rerio) larvae under the same continuous exposure conditions, suggesting that an adaptive detoxification or toxin sequestration mechanism may have evolved in some species of marine fish larvae. Our data reveal that (1) dissolved STX is bioavailable to marine finfish larvae, (2) the toxin is a paralytic agent with potencies that differ between developmental stages, and (3) STX-induced sensorimotor inhibition occurs rapidly but is transient in marine larvae. Collectively, these results suggest that dissolved algal toxins may have important sublethal effects on marine fish populations.

    Full Text Available This commentary examines the contribution in this edition by Roach Anleu & Mack, based on arguments that reducing judicial performance evaluation (ergo any professional performance to that which is easily measurable removes the human aspect of that performance, and is therefore less accurate. Here, “measurable” is meant as focusing only on the “outward performance”, “interaction with stakeholders” and how judges perform in relation to numbers of cases. Compared to such organisational standards, judicial codes of ethics or other written codes reflect the more traditional values of the judiciary, such as independence and impartiality. This can be seen e.g. in the experiences of the Organisation for Security and Cooperation in Europe in supporting the use of judicial performance standards. The argument in the paper, supported by this commentator, is that such exercises are superficial and more depth is needed to capture the entirety of the judicial experience using the model presented. Este comentario analiza el artículo de Roach Anleu y Mack en este número, en base a los argumentos de que limitar la evaluación del rendimiento judicial (ergo cualquier rendimiento profesional a lo que es fácilmente medible elimina el aspecto humano de ese rendimiento, y es por lo tanto menos preciso. Aquí, por “medible” se entiende lo que está centrado únicamente en el “rendimiento exterior”, la “interacción con los interesados” y el rendimiento de los jueces en relación con el número de casos. En comparación con estas normas de organización, los códigos judiciales de ética u otros códigos escritos reflejan los valores más tradicionales de la judicatura, como la independencia o imparcialidad. Esto puede verse, por ejemplo, en las experiencias de la Organización para la Seguridad y la Cooperación en Europa en apoyar el uso de las normas de rendimiento judicial. El argumento del artículo, apoyado por esta autora, es que estos ejercicios son superficiales y se necesita más profundidad para capturar en su totalidad la experiencia judicial utilizando el modelo presentado.

    Full Text Available Nota è la storia della biblica Giuditta, seduttrice e poi omicida per conto di Dio: il generale degli assiri, Oloferne, ha assediato Betulia e la bellissima vedova offre se stessa per salvare la città. Abbigliata con grande sfarzo, uscirà di notte dalle mura, raggiungerà l’accampamento nemico e, dopo aver conquistato l’ignaro comandante, lo ucciderà a tradimento durante il sonno. La pregnanza semantica di una figura come quella della betuliense è dunque particolarmente evidente: la «vedovetta» di petrarchesca memoria incarna, infatti, un prototipo eroico particolarmente complesso, poiché, se da un lato, esso evoca la vittoria del debole sul forte (secondo la vulgata tradizionale, dall’altro, diviene progressivamente emblema di forza e di trasgressione femminile contro la protervia maschile, ben rappresentata da quell’Oloferne che, vinto dall’ebbrezza e dalla concupiscenza, finirà sotto i micidiali colpi della sua spada. Giuditta, protagonista di una fabula di grande potenza narrativa, è dunque una perfetta figura del desiderio: elementi fondanti della storia sono Amore e Morte, seduzione e castrazione, inganno mulìebre, perpetrato grazie all’arte della parola, ed insipienza virile di fronte all’eccezionale bellezza della donna. Nel percorso qui proposto, si evidenziano le profonde somiglianze esistenti fra il personaggio tassiano di Armida, emblema di seduzione entro il campo nemico, e quello biblico di Giuditta. Due “feticci”, due “oggetti” del desiderio maschile destinati ad interpretare la medesima parte (ma con esiti diversi, evidentemente. Lo sguardo si allarga poi all’Europa, con particolare attenzione alla produzione francese, riformata e cattolica (dal poema Judit del Du Bartas fino all’Holoferne. Tragédie sacrée extraite de l’histoire de Iudith dell’ecclesiastico Adrien d’Amboise, infine si analizza il rapporto fra parola e immagine all’interno della tragedia Iudit redatta dall’astigiano Della Valle, ove la nascita del desiderio (in Oloferne coincide con la descrizione di una vestizione mulìebre rimasta celeberrima. La purezza, la fede senza titubanze, l’incontaminata virtù della vedova biblica saranno riprese, all’inizio del Settecento, dalla Betulia liberata di Metastasio, capace di creare un nuovo modello di eroina, che tuttavia non avrà eredi. Nei secoli della modernità, infatti, l’immagine di Giuditta si ergerà ad icona potente di femminilità castratrice e sarà quindi destinata a confondersi con il mito di Salomé, anche grazie a celebri interpretazioni freudiane a noi più vicine.

    Full Text Available In this article I propose to study the interpretation of Butler around dialectics between master and slave. I recognize two original points in her research: the place of the body in Hegel’s philosophy and the role of the unfortunate consciousness. On the other hand, I would like to criticize the link that Butler proposes between the structure of subjection in Hegel and the notion of subjection in Foucault’s writings. I will take distance from Butler’s interpretation, since I prefer to explore a different relationship between both thinkers. Finally, I incorporate the works of Malabou, when she discusses with Butler about the place of the body in Hegel’s philosophy.

For safety reasons, major modifications of the facility had to be fulfilled in advance to the tests. The influence of energy densities has been investigated in the range between 1 and 7 MJ/m{sup 2}. In addition the influence of an increasing number of shots at constant energy density has been studied. For all samples, surface profiles have been measured before and after the experiments. Additional information has been gained from scanning electron microscopy, and from metallography.

  18. Towards a Research Framework for Race in Education: Critical Race Theory and Judith Butler

    Science.gov (United States)

    Chadderton, Charlotte

    2013-01-01

    There has been much debate around the extent to which post-structuralist theory can be applied to critical research. In this article, it is argued that aspects of the two approaches can be combined, resulting in productive tensions that point towards a possible new framework for researching race and racism in education in the UK. The article…

    There is no standard definition of empathy, but the concept is assumed to be innately pro-social and teachable regardless of factors such as power dynamics or other manifestations of social injustice within a society. Such assumptions in discursive practices, whether academic, popular, or pedagogical, obscure the emergence of two important…

  2. Analysis of non-stationary turbulent flows using Multivariate EMD and Matching Pursuits

    Science.gov (United States)

    Mohan, Arvind; Agostini, Lionel; Gaitonde, Datta; Visbal, Miguel

    2016-11-01

    Time-series analysis of highly transient non-stationary turbulent flow is challenging. Traditional Fourier based techniques are generally difficult to apply because of the highly aperiodic nature of the data. Another significant obstacle is assimilating multivariate data, such as multiple variables at a location or from different sources in a flow-field. Such an analysis has the potential to identify sensitive events common among these sources. In this work, we explore two techniques to address these challenges - Multivariate Empirical Mode Decomposition and Matching Pursuits, on deep dynamic stall of a plunging airfoil in a mixed laminar-transitional-turbulent regime. Although primarily used for neuroscience applications, we use them in fluid mechanics and highlight their significant potential to overcome limitations of more traditional techniques. Application of these methods highlight different stages in the development of stall. A first stage shows development of 2-D boundary layer oscillations at frequencies similar to those associated with trailing edge vortices. Subsequently, new instabilities arise due to imminent separation. The separation bubble itself is characterized by relatively higher frequency content, and further analysis indicates its 3-D collapse.

  3. Interplay between <em>De Novo Biosynthesis and Sequestration of Cyanogenic Glucosides in Arthropods

    DEFF Research Database (Denmark)

    Fürstenberg-Hägg, Joel

    Cyanogenic glucosides (CNglcs) are phytoanticipins that are present in more than 2650 plant species. They play an important role in defense against generalist herbivory due to their bitter taste and their hydrolysis upon tissue disruption results in release of toxic hydrogen cyanide. Zygaena larvae....... Adult females are shown to transfer CNglcs to the eggs following emergence from the pupa, providing protection against predation at this vulnerable developmental stage. It is finally speculated that de novo biosynthesis of CNglcs enabled colonization of and subsequently sequestration from the food plant...

    Full Text Available Intersexuality is considered a critical, subversive and deconstructive tool for the categories of sex and gender, in particular from social constructivist theoretical positions well nurtured by post-estructuralist rethoric. The purpose of this article is to discuss the reception of Foucault’s thought in studies on Intersexuality, explain his concepts and how they are incorporated, and which ideas they contribute to destabilizing or reifying within the current debates.

    La Intersexualidad es considerada una herramienta de crítica, subversión y deconstrucción de las categorías sexo y género, singularmente desde posiciones ligadas al constructivismo social y muy nutridas por las retóricas postestructuralistas. La propuesta de este artículo es la de discutir la recepción del pensamiento de Michel Foucault en los estudios sobre la Intersexualidad, y explicar qué conceptos y cómo se incorporan, y qué ideas contribuyen a desestabilizar o reificar dentro de estos debates.

    St. John, C.M.

    1977-04-01

    An underground repository containing heat generating, High Level Waste or Spent Unreprocessed Fuel may be approximated as a finite number of heat sources distributed across the plane of the repository. The resulting temperature, displacement and stress changes may be calculated using analytical solutions, providing linear thermoelasticity is assumed. This report documents a computer program based on this approach and gives results that form the basis for a comparison between the effects of disposing of High Level Waste and Spent Unreprocessed Fuel.

    论文着重批判性地讨论朱迪斯·巴特勒的(跨)性别/酷儿表演性和她在性别三部曲《性别麻烦》《身体之重——论性别的话语界限》及《消解性别》中关于表演性颠覆的理论建构。在第一部分,论文从五个方面深入解读巴特勒的性别表演性理论对奥斯汀言语行为理论的借鉴和改进:一、将言语事件延伸到性别构成;二、视陈述性言语为行为性言语;三、把表演者对权威/习俗的执行修改为对法律/常规的引用;四、认为行为性言语是不断重复、再叙述的动态过程;五、着重"受挫的"言语行为以及颠覆常规的潜质。第二部分重在讨论巴特勒提出的性别表演理论,尤其是性别表演性从内部颠覆性别常规的局限。文章重点探讨性别表演理论几个比较突出的问题:巴特勒将后结构主义方法嫁接到言语行为的可行性问题;表演性的(跨)性别/酷儿转向问题;内部颠覆作为消解性别麻烦的最终策略问题;以及对颠覆本身的酷儿化问题,即引用易装和酷儿作为表演颠覆的原型问题。

    表演性理论可以追溯到奥斯汀以讨论施事行为为核心的言语行为理论,而德里达以"引用性"和"重复性"等概念为主的解构批评为表演性奠定了理论基础.真正使得表演性成为人文社会科学流行话语的,是朱迪斯·巴特勒和她的性别研究.一方面,施事行为和表演性的论述,尤其是德里达的有关观点,是巴特勒的思想资源和理论源泉;另一方面,巴特勒第一次以身体、性别为基础建构了一种新的表演性理论体系.这一理论对后女性主义、酷儿研究、表演研究、文化和政治批评等产生了深刻影响,但是也遭到了一些批评.

    "Organized human endeavor can be lifted an order of magnitude through teaching if it is inspiring" (Editor, Am J Dis Child, 1972). The benevolent influence of Dr. Judy Hall's inspiring clinical teaching in the field of genetic syndromes and birth defects is illustrated through the eventual surgical remediation of conductive hearing loss for a 4-year-old girl with unusual knuckles. The fascinating history of this child's syndrome has been further explored in the descendents of the first Earl of Shrewsbury. The legends of his story and his role in the Hundred Years War were immortalized by William Shakespeare in his play Henry VI Part I, but neither Shakespeare nor historians documented that the Earl actually had abnormal finger joints. Heterozygous mutations in the human noggin gene (NOG) cause a spectrum of joint fusions, including this child's traits. On behalf of practitioners of medicine, pediatrics, clinical genetics, and dysmorphology, as well as research scientists in the many domains of genetics, thank you, Judy, for your inspiration, enthusiasm, and teaching.

    Full Text Available Körperlichkeit und Geschlechterrollen sind jene Themen, die im öffentlichen Diskurs um Religion, vor allem um die drei monotheistischen Religionen, am meisten kontrovers diskutiert werden. Wie sehr der weibliche Körper in der Auseinandersetzung mit Fragen von Macht und Amt, ‚Reinheit‘ und ‚Unreinheit‘, aber auch für das Gottesbild und das Sprechen über Gott eine Rolle spielt, zeigt der vorgestellte Sammelband. Die Autorinnen sind Angehörige des Judentums, Christentums und Islams und geben zu den genannten Themen ihre Perspektive wieder, gehen aber auch auf die jeweils anderen Blickwinkel ein, so dass sich ein überraschend vielschichtiges Bild ergibt. Das Buch stellt einen hochinteressanten Beitrag zur aktuellen Debatte um Religion, Geschlecht und Gesellschaft dar.Corporeality and gender roles are those themes that are most controversial in public discourse on religion, especially in the three monotheistic religions. The collected volume introduced here shows how the female body plays an extensive role in the discussion over questions of power and office, “purity” and “impurity,” but also on the image of God and talking about God. The authors each practice Judaism, Christianity, and Islam and express their individual perspectives on the themes mentioned. They each also respond to the other perspectives. The result is a surprisingly multilayered image. The book represents a very interesting contribution to the current debate on religion, gender, and society.

    Hablar sobre la muerte puede parecer filosófico o teológico. Entrenarse y trabajar periódicamente con la propia mortalidad o con enfermos terminales es otro asunto. Las teorías no sirven de nada cuando morimos, o cuando el que esta muriendo es un ser humano cercano. La muerte en el mejor de los casos produce paz; en condiciones no tan ventajosas es incómoda; en condición habitual, nos aterra y desagrada; y, a veces, nos congela en el pánico.  En Estados Unidos y Europa occidental, hace por lo...

    2015-04-01

    Full Text Available Der zweisprachige Band The Art of Urban Intervention / Die Kunst des urbanen Handelns zeigt anhand einer Bandbreite künstlerischer Projekte in verschiedenen Städten Europas, wie Künstler_innen als Gestalter_innen von Stadt eine aktive und kritische sowie teilweise auch widerständige Rolle in urbanen Transformationsprozessen einnehmen. Sie ermöglichen Begegnungen und Beziehungen zwischen den verschiedenen lokalen Akteur_innen – von Nachbar_innen, Migrant_innen und Händler_innen bis hin zu Immobilienentwickler_innen oder Investor_innen – und werden so Teil von Gemeinschafts- und Sinnstiftung in den vor Ort herrschenden Lebenswelten. Teilweise mit den pragmatischen Realitäten seitens der Stadtplanung und  entwicklung konfrontiert, eignen sich die beteiligten Künstler_innen nicht nur Räume, sondern auch Formen des Einflusses auf die Ausgestaltung der Stadt von morgen an. Neben der rezensierenden Analyse gehen wir zudem kritisch auf den Umgang mit den Begriffen ‚Handeln‘ und ‚Intervention‘ ein.

    朱迪斯·巴特勒的后女性主义理论从质疑和重写以波伏瓦为代表的女性主义理论入手,在消解了生理性别与社会性别的差异性后指出,历来的社会性别都是基于生理性别而建构的,这就道破了男尊女卑之性别秩序的内在机制.巴特勒通过她的性别述行理论揭示了生理性别与社会性别的一致性和建构性,在她看来,宣称性与性别是述行性的,也就是宣称身体从来不是仅仅被陈述或被描述的,而是在描述的过程中被建构的.这就彻底打破了性与性别的稳定性,从而为女性主义理论的发展开启了新的路径.

  4. The Significance of Judith Butler's Theory to Current China's Gender Studies%巴特勒的理论之于中国当代性别研究的意义

    在文化研究的大语境之下,性别研究近十多年来也有了长足的发展,它是传统的女权/性主义的自然延申和在后结构主义时代的最新发展.在性别研究的各种理论中,巴特勒的理论无疑有着最大的影响.经过中国学界的译介,巴特勒的理论在中国也得到一批青年女性研究者的追捧.我们究竟应该如何看待这种现象?作者认为,中国当代社会确实出现了一些令人难以解释的社会和文化现象,这在传统的理论那里是难以解释的,而用巴特勒的理论则至少可以对此加以解释.但另一方面,作者也提请国内学界注意,即使在西方学界,巴特勒的理论也是备受争议的,因此运用于中国社会文化现象的解释必须首先将其“语境化”,并对之进行改造和重构,这样才能达到理论的双向旅行.

    “自我”与“他者”之间的关系是文化身份研究的重要问题之一,也是美国学者朱迪斯·巴特勒身份研究的重要问题.早年巴特勒提出消解身份的激进主张,但近几年日益寻求身份团结,转而结合犹太传统和福柯伦理思想来修正个人主义.巴特勒的新身份主张视“自我”与“他人”为主体间性结构,在这种结构中,各个主体间既有温暖关系又难以避免相互伤害.巴特勒主张当伤害发生时,应当避免以暴制暴,而当视为与他人相遇的特殊机会,重构“人”的身份.

In doing so, she not only addresses a long overdue topic, but she also succeeds in elaborating it on a most abstract level. However, the formalistic consistency that the author uses to advance her research is ambivalent: on the one hand, the reduction of complexity bridges gaps between different disciplines, on the other hand, gender loses meaning if it is eventually subsumed under performance. Consequently, an outline of a general pedagogy, which omits the subject-constituting power of gender, emerges.

    To better understand the evolution modes and self-memory characteristics of the Yellow River annual runoff,a gray self-memory prediction model is developed by using empirical mode decomposition theory.A auto-correlation function is adopted to define the backdate orders of this model to improve its accuracy.The results show that the runoff series at Huayuankou gauge can be decomposed into seven intrinsic mode functions(IMF) and a tendency function.Since 1965 the evolution modes and periodicity of runoff series has changed under the influences by water resources development and climate change in this river basin.%为了研究径流的长期演化模式及自记忆特征,采用自相关函数确定重构序列的回溯阶数,并构建基于经验模态函数(EMD)分解的灰色自记忆GM(1,N)预测模型。分析回溯阶和自相关函数之间关系,进一步阐明自记忆原理在水文领域应用的合理性。结果表明,黄河花园口86年天然径流序列存在长期演化的自记忆特征,演化模式可由7个内在本征模态函数(IMF)和趋势项组成;受流域水资源开发及气候变化因素影响,1965年后,径流演化模式发生变化,出现周期衰减现象;回溯阶与时间序列自相关函数变化相对应,序列平稳化后,依据自相关函数确定回溯阶数,可提高自记忆模型预测精度。

    本文中针对发动机振动信号的非平稳特性,采用经验模式分解方法对信号进行分解,并将其应用于发动机再制造性能的研究中。首先在对振动信号经验模式分解的基础上,引入相关系数表征各IMF分量与原始信号的相关性,并运用关联维数来分析各IMF分量的动态结构。接着为了分析发动机的再制造水平,综合考虑相关系数与关联维数对IMF分量的作用,并将二者有机融合,提出评价发动机再制造水平的一个振动综合度指标,建立了发动机再制造水平与振动综合度之间的对应关系。最后进行了试验研究,结果表明,振动综合度这一指标反映了发动机的运行状态,可以用来评价发动机的再制造水平。%In view of its non-stationary feature, the vibration signal of engine is decomposed by empirical mode decomposition method, which is applied to the study on engine remanufacturing performance in this paper. Firstly on the base of empirical mode decomposition on vibration signal, a concept of‘correlation coefficient’ is in-troduced to characterize the correlation between each intrinsic mode function ( IMF ) components and original sig-nals, and correlation dimension is used to analyze the dynamic structure of each IMF components. Then for studying the remanufacturing level of engine, by concurrently considering the effects of correlation coefficient and correlation dimension on IMF components with both of them organically fused, an indicator of‘overall measure of vibration’ is proposed to evaluate the remanufacturing level of engine with a corresponding relationship between engine remanu-facturing level and the overall measure of vibration established. Finally an experimental study is conducted and the results show that the indicator of ‘overall measure of vibration ’ reflects the operation status of engine and can be used to evaluate the remanufacturing level of engine.

    This paper mainly forecasts the daily closing price of stock markets. We propose a two-stage technique that combines the empirical mode decomposition (EMD) with nonparametric methods of local linear quantile (LLQ). We use the proposed technique, EMD-LLQ, to forecast two stock index time series. Detailed experiments are implemented for the proposed method, in which EMD-LPQ, EMD, and Holt-Winter methods are compared. The proposed EMD-LPQ model is determined to be superior to the EMD and Holt-Winter methods in predicting the stock closing prices.

  16. Emdogain in regenerative periodontal therapy. A review of the literature.

    The goal of regenerative periodontal therapy is the reconstitution of the lost periodontal structures (i.e. the new formation of root cementum, periodontal ligament and alveolar bone). Results from basic research have pointed to the important role of the enamel matrix protein derivative (EMD) in the periodontal wound healing. Histological results from animal and human studies have shown that treatment with EMD promotes periodontal regeneration. Moreover, clinical studies have indicated that treatment with EMD positively influences periodontal wound healing in humans. The goal of the current overview is to present, based on the existing evidence, the clinical indications for regenerative therapy with EMD. Surgical periodontal treatment of deep intrabony defects with EMD promotes periodontal regeneration. The application of EMD in the context of non-surgical periodontal therapy has failed to result in periodontal regeneration. Surgical periodontal therapy of deep intrabony defects with EMD may lead to significantly higher improvements of the clinical parameters than open flap debridement alone. The results obtained following treatment with EMD are comparable to those following treatment with GTR and can be maintained over a longer period. Treatment of intrabony defects with a combination of EMD + GTR does not seem to additionally improve the results compared to treatment with EMD alone or GTR alone. The combination of EMD and some types of bone grafts/bone substitutes may result in certain improvements in the soft and hard tissue parameters compared to treatment with EMD alone. Treatment of recession-type defects with coronally repositioned flaps and EMD may promote formation of cementum, periodontal ligament and bone, and may significantly increase the width of the keratinized tissue. Application of EMD seems to provide better long-term results than coronally repositioned flaps alone. Application of EMD may enhance periodontal regeneration in mandibular Class II

    The Earth Mover Distance (EMD) between point sets A and B is the minimum cost of a bipartite matching between A and B. EMD is an important measure for estimating similarities between objects with quantifiable features and has important applications in several areas including computer vision....... The streaming complexity of approximating EMD between point sets in a two-dimensional discretized grid is an important open problem proposed in [8,9]. We study the problem of approximating EMD in the streaming model, when points lie on a discretized circle. Computing the EMD in this setting has applications...

Specifically, the researchers wish to discover, firstly the students’ habit and attitude in EMD use; secondly, to discover their knowledge with regard to the language learning resources available in EMD; thirdly, to discover their skill in using EMD, and finally, to discover whether there were formal instructions in EMD use when they were studying in their former schools and tertiary education. One hundred and ninety-six students took part in the survey by answering a questionnaire. The results of the study reveal that the respondents were poor users of EMD. They rarely consulted the EMD; their knowledge of the language learning resources in the EMD was limited; most perceived their EMD skill as average, and there was no instruction in EMD when they were at tertiary education and previously when they were at school.

    2011-02-28

    The concomitant influence of grandparental (Generation 1; G1) and parental (G2) substance use disorder (SUD) on grandchild (G3) emotional disorder (EmD) across three generations is unclear. The present study addressed this in a sample of 284 families participating in the Oregon Adolescent Depression Project. Structured clinical interviews were used to collect psychiatric history data on a community cohort of G2 individuals and their G1 parents. G2 parents rated EmD symptoms in their G3 children (M age=5 years, SD=2.4). Results indicated that G1 SUD was associated with increased risk of G3 EmD symptom elevations, above and beyond the influence of comorbid G1 EmD. G2 SUD was associated with a similar independent increase in risk for G3 EmD symptoms. Also, G1 SUD conferred risk for G2 SUD. Mediational tests indicated that the influence of G1 SUD on G3 EmD was transmitted via its influence on G2 SUD. G1 and G2 SUD did not interact in predicting G3 EmD; rather results suggested an additive influence. There was no evidence that the influence of G1 SUD on G3 EmD was transmitted via G2 EmD. These findings shed light on the multigenerational processes through which SUD influences EmD.

    2007-05-01

    Enamel matrix derivative (EMD), such as Emdogain, has been suggested for the improvement of wound healing in periodontal surgical therapy. The present qualitative study seeks to illustrate the ultrastructural changes associated with a human gingival wound at 10 days after the application of EMD as an adjunct to a laterally-positioned flap in a patient with gingival recession. An otherwise healthy patient, who had been suffering from bilateral gingival recession defects on teeth #23 and #26, was studied. One defect was treated with a laterally-positioned flap, while the other was treated with a combination of EMD and a laterally-positioned flap. Ten days after the operation gingival biopsy specimens were obtained from the dentogingival region and examined using a transmission electron microscope. A considerable difference was found in both the cellular and extracellular phases of EMD and non-EMD sites. The fibroblasts of EMD site were more rounded with plump cytoplasms and euchromatic nuclei. A well-developed rough endoplasmic reticulum and numerous mitochondria could be detected. In contrast, the fibroblasts of non-EMD site were of flattened spindle-like morphology. While the signs of apoptosis could rarely be detected at EMD site, apoptotic bodies and ultra-structural evidence of apoptosis (crescent-like heterochromatic nuclei and dilated nuclear envelopes) were consistent features at non-EMD site. The extracellular matrix at EMD site mainly consisted of well-organised collagen fibres, while non-EMD site contained sparse and incompletely-formed collagen fibres. Coccoid bacteria were noted within the extracellular matrix and neutrophils at non-EMD site. It seems that EMD may enhance certain features of gingival wound healing, which may be attributable to its anti-apoptotic, anti-bacterial or anti-inflammatory properties.

  14. Energy-Efficiency Policy Opportunities for Electric Motor-Driven Systems

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2011-07-01

    This publication is the first global analysis of energy consumption and energy efficiency potential of EMDS (electric motor- driven system). The electric motors and systems they drive are the largest single electricity end use, accounting for more than 40% of global electricity consumption. Huge energy efficiency potential was found untapped in EMDS - around 25% of EMDS electricity use could be saved cost-effectively, reducing total global electricity demand by about 10%. However, the energy efficiency of EMDS has been relatively neglected in comparison with other sustainable energy opportunities. It is crucial to scale up the operations and resources committed to realizing the vast savings potential of optimized EMDS. This paper proposes a comprehensive package of policy recommendations to help governments realize the potential for energy savings in EMDS.

Based on the above two theories, an improved EMD method is further proposed. The advantage of the improved EMD is evaluated by a simulated vibration signal. Then this method is applied to study the axle box vibration response caused by wheel flats, considering the influence of both track irregularity and vehicle running speed on diagnosis results. Finally, the effectiveness of the proposed method is verified by a test rig experiment. Research results demonstrate that the improved EMD can inhibit mode mixing phenomenon and extract the wheel fault characteristic effectively.

    Full Text Available Empirical mode decomposition (EMD is particularly useful in analyzing nonstationary and nonlinear time series. However, only partial data within boundaries are available because of the bounded support of the underlying time series. Consequently, the application of EMD to finite time series data results in large biases at the edges by increasing the bias and creating artificial wiggles. This study introduces a new two-stage method to automatically decrease the boundary effects present in EMD. At the first stage, local polynomial quantile regression (LLQ is applied to provide an efficient description of the corrupted and noisy data. The remaining series is assumed to be hidden in the residuals. Hence, EMD is applied to the residuals at the second stage. The final estimate is the summation of the fitting estimates from LLQ and EMD. Simulation was conducted to assess the practical performance of the proposed method. Results show that the proposed method is superior to classical EMD.

    20世纪最后10年,朱迪斯·巴特勒对性别“自然性”的质疑之辩改变了我们思考性别、普适伦理和言语行为的方式.文章以巴特勒的后结构主义女性主义理论为基点,侧重考察性别表演理论之后,她在性别与伦理、伦理与政治之间所进行的理论介入与文化批判的努力.笔者认为,巴特勒质疑女性主义、重构主体的再生产意义和建构美国犹太文化“它者”生存策略是对美国女性主义政治的伦理式演进.尽管巴特勒在世纪之交倡导回归伦理,但她希望保持“伦理两难”的思考状态,让阅读生发更多的问题而非提供思考的结果.她的思考照见了西方人文主义研究中关于人学的一个盲点——人的脆弱性,这或许也是巴特勒无法回避的“伦理两难”的境遇.

    In acute promyelocytic leukemia (APL, extramedullary disease (EMD is particularly rare and shows special clinical and biological features. It is estimated that about 3–5% of APL patients will suffer extramedullary relapse. The most common site of EMD in APL is the CNS.  At present, there are still many issues of EMD in APL needing further clarification, including pathogenesis, risk factors, prognosis and treatment. A better understanding of the biological mechanisms underlying EMD is important to be able to devise more effective CNS prophylaxis and induction-consolidation therapeutic strategies

    Enamel matrix derivative Emdogain (EMD) is widely used in periodontal treatment to regenerate lost connective tissue and to improve the attachment of the teeth. Gelatinases (MMP-2 and -9) have an essential role in the promotion and progression of oral cancer growth and metastasis formation. We studied the effects of EMD on human tongue squamous cell carcinoma (HSC-3) cells in vitro and in vivo. In vitro, EMD (100 microg/ml and 200 microg/ml) remarkably induced the MMP-2 and -9 production from HSC-3 cells analysed by zymography and enzyme-linked immunosorbent assay. EMD also slightly induced the MMP-2 and -9 production from benign human mucosal keratinocytes (HMK). Furthermore, EMD clearly induced the transmigration of HSC-3 cells but had no effect on the HMK migration in transwell assays. The in vitro wound closure of HSC-3 cells was notably accelerated by EMD, whereas it had only minor effect on the wound closure of HMKs. The migration of both cell lines was inhibited by a selective cyclic anti-gelatinolytic peptide CTT-2. EMD had no effect on HSC-3 cell proliferation or apoptosis and only a limited effect on cell attachment to various extracellular matrix components. The in vivo mice experiment revealed that EMD substantially induced HSC-3 xenograft metastasis formation. Our results suggest that the use of EMD for patients with oral mucosal carcinomas or premalignant lesions should be carefully considered, possibly avoided.

    The goal of regenerative periodontal therapy is the reconstitution of the lost periodontal structures (i. e. the new formation of root cementum, periodontal ligament and alveolar bone). Results from basic research have pointed to the important role of an enamel matrix protein derivative (EMD) in periodontal wound healing. Histological results from experiments in animals and from human case reports have shown that treatment with EMD promotes periodontal regeneration. Moreover, clinical studies have indicated that treatment with EMD positively influences periodontal wound healing in humans. The goal of the current overview is to present the clinical indications for regenerative therapy with EMD based on the existing evidence.

    Full Text Available Objective Enamel matrix derivative (EMD is used clinically to promote periodontal tissue regeneration. However, the effects of EMD on gingival epithelial cells during regeneration of periodontal tissues are unclear. In this in vitro study, we purified ameloblastin from EMD and investigated its biological effects on epithelial cells. Material and Methods Bioactive fractions were purified from EMD by reversed-phase high-performance liquid chromatography using hydrophobic support with a C18 column. The mouse gingival epithelial cell line GE-1 and human oral squamous cell carcinoma line SCC-25 were treated with purified EMD fraction, and cell survival was assessed with a WST-1 assay. To identify the proteins in bioactive fractions of EMD, we used proteome analysis with two-dimensional gel electrophoresis followed by identification with liquid chromatography-tandem mass spectrometry (LC-MS/MS analysis. Results Purified fractions from EMD suppressed proliferation of GE-1 and SCC-25. LC-MS/MS revealed that ameloblastin in EMD is the component responsible for inhibiting epithelial cell proliferation. The inhibitory effect of ameloblastin on the proliferation of GE-1 and SCC-25 was confirmed using recombinant protein. Conclusion The inhibitory effects of EMD on epithelial cell proliferation are caused by the biological activities of ameloblastin, which suggests that ameloblastin is involved in regulating epithelial downgrowth in periodontal tissues.

    The use of various combinations of enamel matrix derivative (EMD) and grafting materials has been shown to promote periodontal wound healing/regeneration. However, the downstream cellular behavior of periodontal ligament (PDL) cells and osteoblasts has not yet been studied. Furthermore, it is unknown to what extent the bleeding during regenerative surgery may influence the adsorption of exogenous proteins to the surface of bone grafting materials and the subsequent cellular behavior. In the present study, the aim is to test EMD adsorption to the surface of natural bone mineral (NBM) particles in the presence of blood and determine the effect of EMD coating to NBM particles on downstream cellular pathways, such as adhesion, proliferation, and differentiation of primary human osteoblasts and PDL cells. NBM particles were precoated in various settings with EMD or human blood and analyzed for protein adsorption patterns via fluorescent imaging and high-resolution immunocytochemistry with an anti-EMD antibody. Cell attachment and cell proliferation were quantified using fluorescent double-stranded DNA-binding dye. Cell differentiation was analyzed using real-time polymerase chain reaction for genes encoding runt-related transcription factor 2, alkaline phosphatase (ALP), osteocalcin (OC), and collagen1α1 (COL1A1), and mineralization was assessed using red dye staining. Analysis of cell attachment and cell proliferation revealed significantly higher osteoblast and PDL cell attachment on EMD-coated surfaces when compared with control and blood-coated surfaces. EMD also stimulated release of growth factors and cytokines, including bone morphogenetic protein 2 and transforming growth factor β1. Moreover, there were significantly higher mRNA levels of osteoblast differentiation markers, including COL1A1, ALP, and OC, in osteoblasts and PDL cells cultured on EMD-coated NBM particles. The present results suggest that 1) EMD enhances osteoblast and PDL cell attachment

  10. Relevant modes selection method based on Spearman correlation coefficient for laser signal denoising using empirical mode decomposition

    Empirical mode decomposition (EMD) is a recently proposed nonlinear and nonstationary laser signal denoising method. A noisy signal is broken down using EMD into oscillatory components that are called intrinsic mode functions (IMFs). Thresholding-based denoising and correlation-based partial reconstruction of IMFs are the two main research directions for EMD-based denoising. Similar to other decomposition-based denoising approaches, EMD-based denoising methods require a reliable threshold to determine which IMFs are noise components and which IMFs are noise-free components. In this work, we propose a new approach in which each IMF is first denoised using EMD interval thresholding (EMD-IT), and then a robust thresholding process based on Spearman correlation coefficient is used for relevant modes selection. The proposed method tackles the problem using a thresholding-based denoising approach coupled with partial reconstruction of the relevant IMFs. Other traditional denoising methods, including correlation-based EMD partial reconstruction (EMD-Correlation), discrete Fourier transform and wavelet-based methods, are investigated to provide a comparison with the proposed technique. Simulation and test results demonstrate the superior performance of the proposed method when compared with the other methods.

    In the event of a cardiac arrest, emergency medical dispatchers (EMDs) play a critical role by providing telephone-assisted cardiopulmonary resuscitation (T-CPR) to laypersons. The aim of our investigation was to describe compliance with the T-CPR protocol, the performance of the laypersons in a simulated T-CPR situation, and the communication between laypersons and EMDs during these actions. We conducted a retrospective observational study by analysing 20 recorded video and audio files. In a simulation, EMDs provided laypersons with instructions following T-CPR protocols. These were then analysed using a mixed method with convergent parallel design. If the EMDs complied with the T-CPR protocol, the laypersons performed the correct procedures in 71% of the actions. The single most challenging instruction of the T-CPR protocol, for both EMDs and laypersons, was airway control. Mean values for compression depth and frequency did not reach established guideline goals for CPR. Proper application of T-CPR protocols by EMDs resulted in better performance by laypersons in CPR. The most problematic task for EMDs as well for laypersons was airway management. The study results did not establish that the quality of communication between EMDs and laypersons performing CPR in a cardiac arrest situation led to statistically different outcomes, as measured by the quality and effectiveness of the CPR delivered.

    Detrended fluctuation analysis (DFA) is a simple but very efficient method for investigating the power-law long-term correlations of non-stationary time series, in which a detrending step is necessary to obtain the local fluctuations at different timescales. We propose to determine the local trends through empirical mode decomposition (EMD) and perform the detrending operation by removing the EMD-based local trends, which gives an EMD-based DFA method. Similarly, we also propose a modified multifractal DFA algorithm, called an EMD-based MFDFA. The performance of the EMD-based DFA and MFDFA methods is assessed with extensive numerical experiments based on fractional Brownian motion and multiplicative cascading process. We find that the EMD-based DFA method performs better than the classic DFA method in the determination of the Hurst index when the time series is strongly anticorrelated and the EMD-based MFDFA method outperforms the traditional MFDFA method when the moment order q of the detrended fluctuations is positive. We apply the EMD-based MFDFA to the 1 min data of Shanghai Stock Exchange Composite index, and the presence of multifractality is confirmed. We also analyze the daily Austrian electricity prices and confirm its anti-persistence.

    The enamel matrix derivative (EMD) has a positive effect on the proliferation of human periodontal ligament cells and the healing of periodontal tissues. The aim of this study was to evaluate the effects of EMD on the proliferation and differentiation of human dental pulp cells (hDPCs) in vitro. hDPCs were isolated from human impacted third molars and cultured in vitro. After treatment with100μg/mL EMD, the proliferation of hDPCs was determined by a cell counting kit 8 (CCK8) assay. After incubation in EMD osteogenic induction medium for 14 days, the osteogenic differentiation of hDPCs was evaluated by alkaline phosphatase (ALP) activity, alizarin staining and the expression of osteogenesis-related genes. The EMD osteogenic induction medium enhanced the proliferation of hDPCs. After osteogenic induction, EMD increased the osteogenic potential of hDPCs, as measured by alkaline phosphatase activity and calcium accumulation; the expression levels of osteogenesis-related genes, such as ALP, DSPP, BMP, and OPN were also upregulated. In addition, the expression levels of odontogenesis-related transcription factors Osterix and Runx2 were upregulated. EMD could enhance the mineralization of hDPSCs upregulated the expression of markers for odontoblast/osteoblast-like cells. Further studies are required to determine if EMD can improve pulp tissue repair and regeneration. Copyright © 2013. Published by Elsevier Ltd.

    Our purpose was to determine how enamel matrix derivative (EMD) affects the expression of osteogenesis-and chondrogenesis-related transcription factors in undifferentiated mesenchymal cells.C3H10T1/2 cell line, a typical pluripotential mesenchymal cell line, was cultured with or without EMD for up to 7 d. Expression of mRNAs encoding osteogenesis-and chondrogenesis-related transcription factors(Runx2, Osterix, AJ18, Dlx5, Msx2, Sox5, Sox9 and Zfp60) was measured using real-time polymerase chain reaction. Runx2 and Sox9 protein expression and the presence of bone morphogenetic protein (BMP)-6-like molecules in EMD were determined by Western blotting. EMD substantially increased mRNA levels of osteogenesis-and chondrogenesis-related transcription factors. EMD also induced Runx2 and Sox9 protein expression. Western blotting analysis of EMD using anti-BMP-6 antibody revealed immunoreactive bands corresponding to about 14 kDa and 60 kDa. These results suggest that EMD stimulates osteogenesis-and chondrogenesis-related transcription factors, and these activities may be mediated, at least in part, by BMP-6in EMD.

    This study investigated the effect of enamel matrix derivative (EMD) on spreading, proliferation, and differentiation of osteoblasts cultured on zirconia disks with smooth and rough surfaces. EMD was added to the culture medium or coated on zirconia disks that had machined (smooth) or sandblasted (rough) surfaces. The effects of EMD on cell proliferation of MC3T3-E1 osteoblastic cells were examined using a hemocytometer. Osteoblastic differentiation was examined by histologic analysis of alkaline phosphatase (ALP) activity and the degree of mineralization. ALP activity was also measured quantitatively. Scanning electron microscopic analysis was performed to observe cell morphology. Enzyme-linked immunosorbent assay of osteocalcin and reverse-transcriptase polymerase chain reaction of osteocalcin, osteopontin, and type 1 collagen were performed to investigate the expression of osteoblast-related genes. The addition of EMD to the medium enhanced the spreading, proliferation, and differentiation of osteoblasts cultured on zirconia. However, when it was coated on zirconia, EMD reduced osteoblastic spreading and adhesion in the early stage of culture, although it enhanced proliferation and differentiation of osteoblasts in later stages. A promotive effect of EMD on osteocalcin mRNA expression, mineralization, and ALP activity of osteoblasts cultured on the rough surface was observed. EMD may contribute to treatment with zirconia implants via its promotion of osteoblastic proliferation and activity. However, the procedure for application of EMD may be a crucial factor for the outcome of implants.

    This systematic review focused on the question, if and to what extent enamel matrix derivative (Emdogain) [EMD]) promotes the regeneration of bone. The influence of combinations with other biomaterials was additionally evaluated. Twenty histomorphometric studies were included in this systematic review. Main results of the reviewed articles were (i) guide tissue regeneration (GTR) of infrabony defects seems to result in a higher degree of bone regeneration compared to treatment with EMD; (ii) combined therapy (GTR + EMD) of infrabony defects might not lead to better results than GTR therapy alone; (iii) there seems to be no additional benefit of combined therapy (GTR + EMD) in furcation defects over GTR therapy alone; (iv) EMD seems to lead to more bone regeneration of infrabony defects compared to open flap debridement; (v) however, EMD application might result in more bone formation when applied in supporting defects compared to nonsupporting defects; and (vi) EMD does not seem to promote external jaw/parietal bone formation in the titanium capsule model. The results of one study that suggest that EMD increases the initial growth of trabecular bone around endosseous implants by new bone induction need to be confirmed by additional research.

    Emdogain (EMD) is an enamel matrix derivative extracted from developing porcine teeth with demonstrated periodontal regenerative potential. EMD has been shown to influence a number of properties of periodontal ligament cells including proliferation, cell attachment and matrix synthesis. To date, the effect of EMD on the epithelial cell rests of Malassez (ERM) is unknown. In this study, periodontal ligament fibroblasts, ERM, alveolar bone cells and gingival fibroblasts were obtained from porcine periodontal ligament, alveolar bone and gingiva. This study investigated, in vitro, the effect of EMD at three concentrations on proliferation, cell attachment and expression of mRNA for two mineralised tissue-related proteins (osteopontin and bone sialoprotein). As for other periodontal cells, the ERM proliferative response was enhanced by EMD. Attachment assays revealed a highly significant increase for ERM and gingival fibroblasts after EMD treatment at all concentrations. This study has also shown that EMD stimulated expression of osteopontin mRNA by ERM and alveolar bone cells. The results from this study provide evidence that EMD enhanced cellular events related with proliferation, attachment and osteopontin mRNA expression by porcine periodontal cells, in a manner consistent with its role in periodontal regenerative therapy.

    Full Text Available Enamel matrix derivative (EMD has been found to induce reactive dentin formation; however the molecular mechanisms involved are unclear. The effect of EMD (5–50 μg/mL on primary human pulp cells were compared to untreated cells and cells incubated with 10−8 M dexamethasone (DEX for 1, 2, 3, 7, and 14 days in culture. Expression analysis using Affymetrix microchips demonstrated that 10 μg/mL EMD regulated several hundred genes and stimulated the gene expression of proteins involved in mesenchymal proliferation and differentiation. Both EMD and DEX enhanced the expression of amelogenin (amel, and the dentinogenic markers dentin sialophosphoprotein (DSSP and dentin matrix acidic phosphoprotein 1 (DMP1, as well as the osteogenic markers osteocalcin (OC, BGLAP and collagen type 1 (COL1A1. Whereas, only EMD had effect on alkaline phosphatase (ALP mRNA expression, the stimulatory effect were verified by enhanced secretion of OC and COL1A from EMD treated cells, and increased ALP activity in cell culture medium after EMD treatment. Increased levels of interleukin-6 (IL-6, interleukin-8 (IL-8, and monocyte chemoattractant proteins (MCP-1 in the cell culture medium were also found. Consequently, the suggested effect of EMD is to promote differentiation of pulp cells and increases the potential for pulpal mineralization to favor reactive dentine formation.

    Determining the temperature distribution of coronal plasmas can provide stringent constraints on coronal heating. Current observations with the Extreme ultraviolet Imaging Spectrograph onboard Hinode and the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory provide diagnostics of the emission measure distribution (EMD) of the coronal plasma. Here we test the reliability of temperature diagnostics using 3D radiative MHD simulations. We produce synthetic observables from the models, and apply the Monte Carlo Markov chain EMD diagnostic. By comparing the derived EMDs with the "true" distributions from the model we assess the limitations of the diagnostics, as a function of the plasma parameters and of the signal-to-noise of the data. We find that EMDs derived from EIS synthetic data reproduce some general characteristics of the true distributions, but usually show differences from the true EMDs that are much larger than the estimated uncertainties suggest, especially when structures with signif...

  5. Emdogain in carcinogenesis: a systematic review of in vitro studies.

    2010-03-01

    Emdogain is a commercial product of unknown composition and is clinically used to induce periodontal regeneration. This study aims to review current knowledge of the in vitro effects of Emdogain on oral tissues and, in particular, factors related to carcinoma. A systematic approach was used to review studies from the Embase and Pubmed databases; a total of 76 studies were included. These comprised in vitro studies of the cytokines in, or regulated by, Emdogain and assays designed to study the effects of EMD on human cells in oral tissues or malignant cells. Several studies have shown that EMD regulates the proliferation, migration, adhesion, gene expression, and cytokine production of (pre-)osteoblasts, periodontal fibroblasts, and gingival fibroblasts. However, the effects of EMD on malignant oral cells are not well understood. EMD seems to have broad regulatory effects on malignant cells and on several carcinoma-related factors. Evidence suggests that patients with premalignant or malignant mucosal lesions should not be treated with EMD.

    2006-08-01

    Full Text Available Background and Aim: Intrabony periodontal defects are important problems in periodontology and up to now several ways have been suggested for their treatment .Treatment with enamel matrix derivatives (EMD has been shown to enhance periodontal regeneration. There is limited information available from clinical trials regarding the performance of EMD in the treatment of periodontal intrabony defects. This study was designed to compare the clinical and radiographic effects of EMD treatment to that of open flap debridment (OFD for two and three walled intrabony defects. Materials and Methods: 18 patients were included in this clinical trial which have 24 two and/ or three intrabony defects. Defects were randomly divided into two groups (test and control. Defects in test group were treated with flap surgery plus EMD and in control group with open flap debridment. At baseline and at 3 and 6 months follow up, clinical and radiographic measurements were performed. Data were analyzed using Greenhouse-Geisser test with p<0.05 as the limit of significance. Results: At 3 and 6 months, mean probing pocket depth reduction was greater in the test group (EMD (4.33 mm and 4.70 mm compared to the OFD group (2.54 mm and 3.09 mm. Mean values for clinical attachment gain in the EMD group after 3 and 6 months were 4.29 mm and 4.98 mm, and in OFD group were 2.83 and 2.82 mm respectively. Radiographic bone gain measured by radiovisiography technique was greater in the EMD group compared to the OFD group (4.66 mm in EMD and 1.11 mm in OFD group after 3 months and 5.78 mm in EMD and 1.39 mm in OFD group after 6 months. Conclusion: Based on the results of this study, treatment with flap surgery and EMD compared to open flap debridment, produced more favorable clinical improvements in two and three walled intrabony defects.

  16. Osteoblast response (initial adhesion and alkaline phosphatase activity following exposure to a barrier membrane/enamel matrix derivative combination

    Directory of Open Access Journals (Sweden)

    Thangakumaran S

    2009-01-01

    Full Text Available Background and Objective: The enamel matrix derivative (EMD has been used in combination with barrier membranes to optimize regeneration in vertical osseous defects. However, the osteoblast response when exposed to the EMD/barrier membrane combination has not yet been evaluated. The osteoblast behavior when exposed to a combination of regenerative materials must be evaluated to fully understand their effect on bone regeneration. Therefore, the present study was undertaken to estimate the initial adhesion and alkaline phosphatase (ALP activity of an osteoblast cell line (SaOS-2 when exposed to four commercially available resorbable membranes and determine if the addition of EMD had any modulatory effect on osteoblast behavior. Materials and Methods: 5 x 104 SaOS-2 cells between passages 7-10 were cultured in two 24-well culture plates. Plate A was used for the adhesion assay and Plate B was used for the ALP assay. A MTT (3-[4, 5-dimethylthiazolyl-2]-2, 5-diphenyltetrazolium bromide assay was done after 24 hours to determine the adhesion of the osteoblastic cells to four barrier membranes: 1 a non cross-linked porcine Type I and III collagen membrane (BG, 2 a weakly cross-linked Type I collagen membrane (HG, 3 a glutaraldehyde cross-linked bovine Type I collagen (BM, and 4 a resorbable polymer membrane (CP. Osteoblast differentiation was studied using an ALP assay with p-nitro phenyl phosphate as the substrate at 24 hours, 72 hours, and 1 week. A total of 50 µg/ml of EMD dissolved in 10 mM acetic acid was added into each well and the entire experimental protocol outlined above was repeated. Results: The osteoblast adhesion to collagen barriers showed a statistically insignificant reduction following the addition of EMD. Adhesion to the polymer barrier, although significantly lower when compared with collagen barriers, was unaffected by the addition of EMD. ALP activity after 1 week among the various groups was as follows: EMD alone (75.59±2

  7. Electrode microwave discharge: Areas of application and recent results of discharge physics

    2010-01-01

    The first paper on the electrode microwave discharge (EMD) appeared in 1996. Presently many problems of EMD physics and applications have already been solved. Several examples of EMD application are discussed: diamond growth, deposition of CNx films and nanotubes, deposition of metal films (Cu, Al), deposition of TiN and TiO2 films, generation of O2(a1Δ), and EMD as a plasma cathode. Results of EMD experiments and modeling give rise to the assumption that an EMD consists of a self-sustained domain (near-electrode plasma region with overcritical plasma density) which is surrounded by a region of a non-self-sustained discharge (ball shaped region with undercritical plasma density). We assumed that the layer of charge separation and of induced electrostatic field originated at the outer EMD boundary was one of the reasons for the abrupt decrease of the plasma density which leads to the formation of a compact plasma structure. Recent modeling results of the strongly nonuniform electrode microwave plasma based on a quasi static, 1D spherically symmetric model showed that such a layer can be generated at the point where a sudden increase of the total ionization rate takes place.

    In the past decade, rapid technological developments have advanced electronic monitoring devices (EMD) for asthma inhalers beyond simple recording of actuations to providing adherence promotion features and detailed information about patterns of medication use. This article describes currently available EMDs, discusses their utility and limitations in assessing adherence, and describes the potential for EMD-based adherence promotion interventions in clinical settings. To date, the main use of EMDs has been in clinical research. In selected populations, simple EMD-based adherence interventions, delivered either through clinician-to-patient feedback about medication use or by direct-to-patient reminders for missed doses, can significantly improve adherence. Further work is now needed to determine the impact of EMDs on clinical outcomes and their cost-effectiveness and feasibility for different clinical settings, including in disadvantaged populations. If this evidence can be provided, then the use of EMDs could expand into the management of asthma in populations with high health care costs, eg, severe asthma. In the future, medication monitoring could help distinguish poor treatment response from poor adherence, guide prescribing decisions, and prompt providers to discuss barriers to adherence; electronic health records may provide the gateway for integrating medication-use monitoring into digital chronic care management.

    The aim of this study was to evaluate atrial electromechanical delay (EMD), P wave dispersion (Pwd), and left atrial (LA) mechanical functions in patients with active acromegaly. Twenty-three patients with active acromegaly and 27 age- and sex-matched controls were included in this study. All atrial electromechanical interval parameters (PA lateral, PA septum, PA tricuspid, interatrial EMD, intra-LA EMD, and intra-right atrial EMD) were measured from mitral lateral annulus, mitral septal annulus, and right ventricular tricuspid annulus by tissue Doppler imaging. LA volumes were measured by the disk method in the apical four-chamber view and were indexed to the body surface area. Mechanical function parameters of LA were calculated. Pwd was performed by 12-lead electrocardiograms. Atrial electromechanical intervals (PA lateral, PA septum, PA tricuspid, interatrial EMD, intra-LA EMD, and intra-right atrial EMD) and Pwd were similar between patients with acromegaly and control subjects (all p > 0.05). LA volumes (maximum, minimum, and presystolic) and LA mechanical functions were not significantly different between the groups (all p > 0.05). Additionally, serum levels of growth hormone and insulin-like growth factor-1 were not correlated with atrial electromechanical parameters and LA mechanical functions. Atrial electrical conduction times were not prolonged and LA mechanical functions were not impaired in patients with active acromegaly compared with controls. And the prevalence of supraventricular arrhythmia risk may not increase in this population.

    Full Text Available The e phase of electrolytic manganese dioxide (EMD is the structural form most easily converted in the LiMn2O4 spinel used as cathode in lithium batteries. Thus, employing titanium as anode, a study of electrolysis parameters was carried out in order to determine the best conditions to produce an e-EMD suitable for that spinel preparation. The influence of solution temperature (65oC and 90oC and current density (between 1 mA/cm2 and 17.5 mA/cm2 on the anode potential and the EMD properties was investigated using an aqueous 2.0 mol/L MnSO4 + 0.30 mol/L H2SO4 solution. In any of the electrolysis conditions tested only the e-EMD structure was obtained, but its specific surface area varied with the applied current density and temperature. Drying the e-EMD at temperatures between 60oC and 120oC did not cause any phase changes. To produce a suitable EMD at the highest current density possible without passivation of the titanium anode, the best electrolysis parameters were determined to be 90oC and 15 mA/cm2. The e-EMD thus obtained had a specific surface area (BET of ca. 65 m2/g.

    Aim: The aim of this study is to evaluate the response of human pulp tissue to mineral trioxide aggregate (MTA), Emdogain (EMD), and combination of MTA/EMD. Materials and Methods: This study was performed on sixty intact first and second premolars of human maxillary and mandibular teeth. A standard pulpal exposure was done on all the teeth and was divided into three groups of twenty teeth each and was capped with MTA, EMD, and MTA/EMD combination. The final restoration was done with resin-modified glass ionomer cement. The teeth were then extracted on the 15th or 45th day and histological evaluation done. Results: Differences in inflammatory response and thickness of dentin bridge formation of the exposed pulp to the three different groups were statistically evaluated using Chi-square and Mann–Whitney tests and were found to be significant. No significant difference was found between MTA/EMD and MTA in terms of calcified bridge formation and pulp inflammatory response to the capping materials. Conclusions: MTA and MTA/EMD combination produced a better quality hard tissue response compared with the use of EMD. PMID:27994315

    Modifications of implant surface topography and chemistry have proven a means to enhance osseointegration, a process that ensures the stability of bone-contacting devices, including titanium dental implants. The commercial product Emdogain is an enamel matrix derivative (EMD) extracted from porcine teeth commonly used in periodontal surgery, where it has been shown to potentiate regeneration of bone. The aim of the present study was to evaluate the effect of EMD on the attachment, proliferation and differentiation of osteoblasts on titanium surfaces in vitro. Pickled (smooth) and SLA (roughened) titanium discs were coated with EMD or left uncoated. Primary rat calvarial osteoblasts were cultured on each surface from 1h to 4 weeks. EMD significantly increased cell spreading and proliferation at time points ranging from 3 to 7 days on both topographies. Alkaline phosphatase activity was significantly increased on EMD-coated titanium compared with titanium alone. Moreover, there was a 6 fold increase in levels of mRNA encoding bone sialoprotein and osteocalcin in osteoblasts cultured on EMD-coated titanium surfaces compared with uncoated surfaces. We conclude that coating of titanium with EMD enhances the proliferation and differentiation of osteoblasts irrespective of the titanium substratum topography.

    Although enamel matrix derivative (EMD) has been used to promote periodontal regeneration, little is known of its effect on the microbiome. Therefore, this investigation aims to identify changes in periodontal microbiome after treatment with EMD using a deep-sequencing approach. Thirty-nine patients with mandibular Class II buccal furcation defects were randomized to beta-tricalcium-phosphate/hydroxyapatite graft (BONE group), EMD+BONE, or EMD alone. Plaque was collected from furcation defects at baseline and 3 and 6 months post-treatment. Bacterial DNA was analyzed using terminal restriction fragment length polymorphism and 16S pyrotag sequencing, resulting in 169,000 classifiable sequences being compared with the Human Oral Microbiome Database. Statistical comparisons were made using parametric tests. At baseline, a total of 422 species were identified from the 39 defects, belonging to Fusobacterium, Pseudomonas, Streptococcus, Filifactor, and Parvimonas. All three regenerative procedures predictably altered the disease-associated microbiome, with a restitution of health-compatible species. However, EMD and BONE+EMD groups demonstrated more long-term reductions in a higher number of species than the BONE group (P <0.05), especially disease-associated species, e.g., Selenomonas noxia, F. alocis, and Fusobacterium. EMD treatment predictably alters a dysbiotic subgingival microbiome, decreasing pathogen richness and increasing commensal abundance. Further investigations are needed to investigate how this impacts regenerative outcomes.

    Although mnemonics are commonly used in medical education there are few data on their effectiveness. A RCT was undertaken to test the hypothesis that a new aide memoire, "EMD-aide", would be superior to the conventional "4Hs+4Ts" mnemonic in facilitating recall of causes of electromechanical dissociation (EMD) among house officers. "EMD-aide", organises causes of EMD by frequency of occurrence and ease of reversibility: four groups organised by shape, colour, position, numbering, clockwise sequence, and use of arrows. Eight hospitals were randomised in a controlled trial and 149 house officers were then recruited by telephone. Baseline ability to recall causes of EMD was recorded at one minute and overall. House officers were then sent a copy of either "4Hs+4Ts" or "EMD-aide" according to randomisation group. Recall ability was retested at one month. 68 of 80 and 51 of 69 house officers completed the study in the "4Hs+4Ts" and "EMD-aide" groups respectively (NS) with similar baseline recall. After intervention median number of recalled causes was greater in the "EMD-aide" group, eight compared with seven at one minute (p = 0.034) and eight compared with seven overall, p = 0.067. Recall of all eight causes was more common in "EMD-aide" group, 54% compared with 35%, p = 0.054, and these house officers spent longer examining their aide memoire, pEducational psychology of medical learning and the use of aide memoires in general are worthy of further study.

    Enamel matrix derivative (EMD) is an effective biomaterial for periodontal tissue regeneration and might stimulate angiogenesis. In order to clarify mechanisms underlying its biological activity, we separated two EMD fractions with different molecular weight protein components and investigated their effects on human umbilical vein endothelial cells (HUVECs) in vitro. Fraction Low-Molecular Weight (LMW) included proteins with a molecular weight (M.W.)8kDa and lower than approximately 55kDa. The effect of EMD fractions on proliferation/viability, apoptosis, migration and expression of angiopoetin-2 (ang-2), von Willebrand factor (vWF), E-selectin, intracellular adhesion molecules 1 (ICAM-1), vascular endothelial growth factor (VEGF) receptors Flt-1 and KDR was investigated. The proliferation/viability of HUVECs was inhibited by both LMW and LMW-depleted at concentrations 100μg/ml, whereas EMD slightly increased cell proliferation/viability. The expression of all investigated proteins was up-regulated by EMD. However, differences in the effect of EMD fractions on the protein expression were observed. The effect of LMW-depleted on the expression of ICAM-1 and E-selectin was markedly higher compared to LMW. In contrast, the expression of vWF and VEGF receptors Flt-1 and KDR was primarily affected LMW than by LMW depleted. The expression of ang-2 was not influenced by LMW and LMW-depleted. HUVECs migration was stimulated more strongly by LMW than by EMD and LMW-depleted. Our in vitro study shows that the proteins composing EMD have different and specific biological activities and consequently have the ability to cover different aspects of EMD's biological and clinical effects.

    Full Text Available Objectives The effects of bone morphogenetic protein-2 (BMP-2 and enamel matrix derivative (EMD respectively with mineral trioxide aggregate (MTA on hard tissue regeneration have been investigated in previous studies. This study aimed to compare the osteogenic effects of MTA/BMP-2 and MTA/EMD treatment in MC3T3-E1 cells. Materials and Methods MC3T3-E1 cells were treated with MTA (ProRoot, Dentsply, BMP-2 (R&D Systems, EMD (Emdogain, Straumann separately and MTA/BMP-2 or MTA/EMD combination. Mineralization was evaluated by staining the calcium deposits with alkaline phosphatase (ALP, Sigma-Aldrich and Alizarin red (Sigma-Aldrich. The effects on the osteoblast differentiation were evaluated by the expressions of osteogenic markers, including ALP, bone sialoprotein (BSP, osteocalcin (OCN, osteopontin (OPN and osteonectin (OSN, as determined by reverse-transcription polymerase chain reaction analysis (RT-PCR, AccuPower PCR, Bioneer. Results Mineralization increased in the BMP-2 and MTA/BMP-2 groups and increased to a lesser extent in the MTA/EMD group but appeared to decrease in the MTA-only group based on Alizarin red staining. ALP expression largely decreased in the EMD and MTA/EMD groups based on ALP staining. In the MTA/BMP-2 group, mRNA expression of OPN on day 3 and BSP and OCN on day 7 significantly increased. In the MTA/EMD group, OSN and OCN gene expression significantly increased on day 7, whereas ALP expression decreased on days 3 and 7 (p < 0.05. Conclusions These results suggest the MTA/BMP-2 combination promoted more rapid differentiation in MC3T3-E1 cells than did MTA/EMD during the early mineralization period.

    An empirical mode decomposition (EMD) approach to the harmonic signal extraction from chaotic interference is proposed. Based on the EMD and the concept that any signal is composed of a series of simple intrinsic modes, the chaotic interference signal is decomposed to a series of intrinsic mode functions (IMFs), among which one IMF is the recovered harmonic signal. In this study, harmonic signals are contaminated with a chaotic interference signal which is generated by a Duffing oscillator, and the simulation results show that the harmonic signals can be effectively recovered from the contaminated signals by the EMD approach.

    2004-01-01

    Time synchronous averaging of vibration data is a fundament technique for gearbox diagnosis. Currently, this technique relies on hardware tachometer to give phase synchronous information. Empirical mode decomposition (EMD) is introduced to replace time synchronous averaging of gearbox vibration signal. With it, any complicated dataset can be decomposed into a finite and often small number of intrinsic mode functions (IMF). The key problem is how to assure that vibration signals deduced by gear defects could be sifted out by EMD. The characteristic vibration signals of gear defects are proved IMFs, which makes it possible to utilize EMD for the diagnosis of gearbox faults. The method is validated by data from recordings of the vibration of a single-stage spiral bevel gearbox with fatigue pitting. The results show EMD is powerful to extract characteristic information from noisy vibration signals.

    This study explores the efficacy of eye movement desensitization and reprocessing (EMD/R) in the management of acute pain induced by hand exposures to ice water. Thirty participants were randomly assigned to one of the following interventions: (a) eye movement desensitization and reprocessing, (b) eye movement desensitization with music (EMD/M), and (c) control. The EMD/R participants focused on negative experiences associated with exposure to ice water, generated positive self-talk, and diverted their attention away from pain by focusing on a rapidly moving light on a monitor. The EMD with music group received eye movement desensitization coupled with preferred music. Repeated measures univariate and multivariate analysis of covariance was used to analyze the data. Results indicated that both procedures alleviated participants' pain to a similar degree and significantly more than the control, P < 0.05.

    2008-05-01

    Full Text Available The aim of this paper was to compare empirical mode decomposition (EMD and two new extended methods of  EMD named complex empirical mode decomposition (complex-EMD and bivariate empirical mode decomposition (bivariate-EMD. All methods were used to analyze stabilogram center of pressure (COP time series. The two new methods are suitable to be applied to complex time series to extract complex intrinsic mode functions (IMFs before the Hilbert transform is subsequently applied on the IMFs. The trace of the analytic IMF in the complex plane has a circular form, with each IMF having its own rotation frequency. The area of the circle and the average rotation frequency of IMFs represent efficient indicators of the postural stability status of subjects. Experimental results show the effectiveness of these indicators to identify differences in standing posture between groups.

  5. On identification of elementary motion detectors

    Hidayat, Egi; Medvedev, Alexander; Nordström, Karin

    2013-10-01

    The classical mathematical elementary motion detector (EMD) model stimulated with sinusoidal and pulsatile input signals is treated analytically. Drifting sinusoidal gratings are often used in insect vision research, enabling direct comparison with biological data. When displayed on a cathode ray tube monitor, the sinusoidal grating is modulated by the refresh rate of the monitor. Due to the resulting pulsatile nature of the visual stimuli and the corresponding biological response, a Laguerre domain identification method for estimating the dynamics of a single EMD appears to be suitable. A pool of spatially distributed EMDs is considered as the model for the measured neural output. The weights of the contributing EMDs are evaluated by a sparse optimization method to fit the experimental data.

    Full Text Available Motion detection in the fly is extremely fast with low computational requirements. Inspired from the fly's vision system, we focus on a real-time flight control on a miniquadrotor with fast visual feedback. In this work, an elaborated elementary motion detector (EMD is utilized to detect local optical flow. Combined with novel receptive field templates, the yaw rate of the quadrotor is estimated through a lookup table established with this bioinspired visual sensor. A closed-loop control system with the feedback of yaw rate estimated by EMD is designed. With the motion of the other degrees of freedom stabilized by a camera tracking system, the yaw-rate of the quadrotor during hovering is controlled based on EMD feedback under real-world scenario. The control performance of the proposed approach is compared with that of conventional approach. The experimental results demonstrate the effectiveness of utilizing EMD for quadrotor control.

    Hyperthyroidism is a well-known cause of atrial fibrillation (AF) which is associated with increased morbidity and mortality. Atrial electromechanical delay (EMD) is a significant predictor of AF. The aim of this study was to assess the atrial EMD and diastolic functions in subclinical and overt hyperthyroidism by using tissue Doppler imaging (TDI). The study population consisted of 3 groups: group I (30 healthy subjects), group II (38 patients with subclinical hyperthyroidism), and group III (25 patients with overt hyperthyroidism). Atrial electromechanical coupling was measured with TDI. Standard echocardiographic measurements and parameters of diastolic function were obtained by conventional echocardiography and TDI. Intra- and inter-atrial EMD were significantly prolonged in subclinical and overt hyperthyroidism compared with control group (P = 0.03 and P hyperthyroidism. TSH level and mitral Em /Am ratio were found as independent predictors of atrial EMD. © 2013, Wiley Periodicals, Inc.

    The main objective of this study was to evaluate the clinical effectiveness of platelet-rich fibrin membrane used in combination with a coronally advanced flap (CAF) and to compare it with the use of an enamel matrix derivative (EMD) in combination with a coronally advanced flap in gingival recession treatment. 20 split-mouth cases of maxillary anterior teeth or bicuspids presenting with Miller Class I or II gingival recession were treated with a CAF combined with a platelet-rich fibrin membrane (PRF group) or with EMD (EMD group) placed under a CAF. The following parameters were measured at baseline and at 12 months post treatment: gingival recession (GR), apicocoronal width of the keratinized tissue (WKT), and probing depth (PD). Complete rot coverage in the PRF group was 65% (13 out of 20 recessions) and 60% in the EMD group (12 out of 20 recessions). GR was 4.10 ± 1.05 mm in the PRF group and 3.90 ± 1.00 mm in the EMD group at baseline, and 1.05 ± 0.45 mm in the PRF group and 1.15 ± 0.65 mm in the EMD group at 12 months. The difference observed between the tow groups at 12 months was statistically significant. Average root coverage was 70.5% in the EMD group and 72.1% in the PRF group. WKT was 1.30 ± 0.56 mm in the EMD group and 1.45 ± 0.86 mm in the PRF group at baseline, and 1.90 ± 0.81 mm in the EMD group and 1.62 ± 0.28 mm in the PRF group at 12 months. The difference observed between the two groups at 12 months was not statistically significant. Twelve-month changes in PD were not significantly different between the two groups. The pain intensity was statistically different between the two groups. The pain intensity was statistically different between groups for the first 5 days, favoring the PRF group. The present study did not succeed in demonstrating any clinical advantage of the use of PRF compared to EMD in the coverage of gingival recession with the CAF procedure. The EMD group showed a higher success rate in increasing WKT than did the PRF

    Full Text Available Reconstructive periodontal surgery aims at predictably restoring tooth’s supporting structure lost due to perio‐ dontal disease or trauma. One such modality, which has been demonstrate to promote periodontal regeneration, is an enamel matrix derivative (EMD, consisting of a formu‐ lation of amelogenin proteins from developing porcine enamel. This review article provides a brief update on the effects of blood interaction, occurring during periodontal surgery, on the effectiveness of EMD adsorption on the root surfaces and its implications for periodontal recon‐ structive surgery.The clinical use of an enamel matrix derivative (EMD has been successfully proved in periodontal surgery, as promoting regeneration of periodontal tissues including new cementum, periodontal ligament (PDL and alveolar bone [1]. Despite its widespread use, only recently has the effect of blood, occurring during periodontal surgery, been evaluated for contamination of the effectiveness of EMD adsorption onto root surfaces. The aim of this review arti‐ cle is to provide the clinician a summary of findings from in vitro experiments testing the effects of EMD adsorption onto root surfaces in the presence and absence of blood and its effect on PDL cell behavior [2]. Until recently, the extent to which bleeding occurring during periodontal sur‐ gery affects the adsorption of EMD onto root surfaces could not be established.In summary, the teeth extracted for orthodontic reasons were subject to ex vivo scaling and root planing and expo‐ sed to 6 clinically relevant scenarios, as illustrated in figure 1. EMD application is usually performed following root surface conditioning with 24% EDTA. Findings from high resolution scanning electron microscopy (SEM demons‐ trated that the proteins found in blood (mainly albumin were able to compete with those found in EMD (Figure 2, reducing the effectiveness of EMD thereafter. No apparent effect of conditioning the surface

    Gingival fibroblasts (GFs) play a considerable role in the maintenance of the gingival apparatus as well as in connective tissue repair. Mobility of a periodontal wound or soft tissue graft can impair connective tissue healing from the GFs. Enamel matrix derivative (EMD) is an enamel matrix protein used clinically for periodontal regeneration of intrabony defects and furcations, as well as treatment of gingival margin recessions. The goal of this project was to compare the effects of varying concentrations of EMD, with and without cyclic mechanical strain, on cellular wound fill of human GFs using an in vitro defect healing model. GFs were seeded and cultured in six-well flexible-bottomed plates. A 3-mm wound was created in the central portion of each confluent well. Three wells were treated with each EMD concentration of 0 Μg/mL (control), 30 Μg/mL, 60 Μg/mL, or 120 Μg/mL. The plates were placed in an incubator containing a strain unit to subject test plates to cyclic strain. An identical set of control plates were not flexed. Cells were examined on days 4, 8, 12, and 16. Microphotographs were taken and wound fill measurements made using image analysis software. The percent wound fill was calculated. All nonflexed plates, regardless of EMD concentration, reached > 90% defect fill at similar rates by day 16. However, in the flexed plates, EMD had a significant negative effect on defect fill. The defect fill was 55.7% for 0 Μg/mL EMD, 48.2% for 30 Μg/mL EMD, 36.7% for 60 Μg/mL EMD, and 34.1% for 120 Μg/mL EMD on day 16 for the flexed GFs. EMD, in concentrations as high as 120 Μg/mL, did not significantly affect the amount of defect fill with nonflexed GFs. However, when the GFs were flexed, the addition of EMD had a significant negative effect on defect fill in a dose-dependent manner.

    We introduce a new nonlinear electrophoretic model for complex-forming systems with a fully charged analyte and a neutral ligand. The background electrolyte is supposed to be composed of two constituents, which do not interact with the ligand. In order to characterize the electromigration dispersion (EMD) of the analyte zone we define a new parameter, the nonlinear electromigration mobility slope, S(EMD,A). The parameter can be easily utilized for quantitative prediction of the EMD and for comparisons of the model with the simulated and experimental profiles. We implemented the model to the new version of PeakMaster 5.3 Complex that can calculate some characteristic parameters of the electrophoretic system and can plot the dependence of S(EMD,A) on the concentration of the ligand. Besides S(EMD,A), also the relative velocity slope, S(X), can be calculated. It is commonly used as a measure of EMD in electrophoretic systems. PeakMaster 5.3 Complex software can be advantageously used for optimization of the separation conditions to avoid high EMD in complexing systems. Based on the theoretical model we analyze the S(EMD,A) and reveal that this parameter is composed of six terms. We show that the major factor responsible for the electromigration dispersion in complex-forming electrophoretic systems is the complexation equilibrium and particularly its impact on the effective mobility of the analyte. To prove the appropriateness of the model we showed that there is a very good agreement between peak shapes calculated by PeakMaster 5.3 Complex (plotted using the HVLR function) and the profiles simulated by means of Simul 5 Complex. The detailed experimental verification of the new mode of PeakMaster 5.3 Complex is in the next part IV of the series.

  13. Premature osteoblast clustering by enamel matrix proteins induces osteoblast differentiation through up-regulation of connexin 43 and N-cadherin.

    Richard J Miron

    Full Text Available In recent years, enamel matrix derivative (EMD has garnered much interest in the dental field for its apparent bioactivity that stimulates regeneration of periodontal tissues including periodontal ligament, cementum and alveolar bone. Despite its widespread use, the underlying cellular mechanisms remain unclear and an understanding of its biological interactions could identify new strategies for tissue engineering. Previous in vitro research has demonstrated that EMD promotes premature osteoblast clustering at early time points. The aim of the present study was to evaluate the influence of cell clustering on vital osteoblast cell-cell communication and adhesion molecules, connexin 43 (cx43 and N-cadherin (N-cad as assessed by immunofluorescence imaging, real-time PCR and Western blot analysis. In addition, differentiation markers of osteoblasts were quantified using alkaline phosphatase, osteocalcin and von Kossa staining. EMD significantly increased the expression of connexin 43 and N-cadherin at early time points ranging from 2 to 5 days. Protein expression was localized to cell membranes when compared to control groups. Alkaline phosphatase activity was also significantly increased on EMD-coated samples at 3, 5 and 7 days post seeding. Interestingly, higher activity was localized to cell cluster regions. There was a 3 fold increase in osteocalcin and bone sialoprotein mRNA levels for osteoblasts cultured on EMD-coated culture dishes. Moreover, EMD significantly increased extracellular mineral deposition in cell clusters as assessed through von Kossa staining at 5, 7, 10 and 14 days post seeding. We conclude that EMD up-regulates the expression of vital osteoblast cell-cell communication and adhesion molecules, which enhances the differentiation and mineralization activity of osteoblasts. These findings provide further support for the clinical evidence that EMD increases the speed and quality of new bone formation in vivo.

    This article describes two different surgical techniques of root coverage using Emdogain and shows preliminary results on 26 shallow recessions in 14 patients. For the treatment of 13 recessions, Emdogain was used in combination with a coronally advanced flap (CAF+EMD group). In the other 13 recessions, Emdogain and the flap were used in combination with a subepithelial connective tissue graft (CAF+CTG+EMD group). For the CAF+EMD group, the root coverage at 6 months was 93.97%, with an attachment gain of 3.2 mm; for the CAF+CTG+EMD group, the root coverage was 93.59%, with an attachment gain of 3.4 mm (no statistically significant difference between groups). When complete root coverage was not achieved, the residual recession was 1 mm in four cases and 2 mm in one case. Keratinized gingiva was increased for both groups, but more for the CAF+CTG+EMD group (1.38 mm versus 0.69 mm; statistically significant difference). Clinical attachment level decreased significantly in both groups, from 4.46 to 1.23 mm in the CAF+EMD group, and from 4.62 to 1.23 mm in the CAF+CTG+EMD group. Preliminary results show that Emdogain, in combination with CAF or CAF+CTG for the treatment of Miller Class I or II gingival recessions, displays good clinical results, with percentage of root coverage comparable or superior to other techniques. Further experimental studies on the dynamics of wound healing are needed to prove that EMD is really responsible for improving the percentage of regenerated versus repaired tissues with respect to other techniques.

    When measured in vivo electromechanical delay (EMD) depends mainly on the elastic properties of the muscle-tendon unit. Recent studies have shown changes in stiffness of the triceps surae (TS) following a period of training. To confirm the influence of musculo-tendinous stiffness on EMD, this study investigates paired changes in these two parameters after a training period. Two types of training known to induce opposite changes in stiffness were analysed. EMD and musculo-tendinous stiffness were measured on adult subjects before and after 10 weeks of endurance (n = 21) or plyometric (n = 9) trainings. EMD was defined as the time lag between the TS M-wave latency and the onset of muscle twitch evoked at rest by supramaximal electrical stimulations of the posterior tibial nerve. Quick release tests were used to evaluate the musculo-tendinous stiffness of the ankle plantar flexors. The stiffness index was defined as the slope of the relationship between angular stiffness and external torque values. Endurance training, known to preferentially activate the slow, stiffer muscle fibers, leads to a decrease in EMD and to an increase in stiffness index. Following plyometric training, which specifically recruits fast, more compliant fibers, EMD and the stiffness index exhibited adaptations directionally opposite to those seen with endurance training. When pooling the data for the two subject groups, a correlation was found between changes in EMD and changes in musculo-tendinous stiffness indexes. Thus, changes in EMD values are proposed to indirectly link to changes in musculo-tendinous stiffness for subjects involved in muscle training.

    The combination of osseous graft with barrier membrane and enamel matrix protein derivative (EMD) has the potential to result in a synergistic effect. Therefore, the aim of this study was to evaluate the effectiveness of EMD in combination with demineralized freeze-dried bone allograft (BG) and bioresorbable membrane (Biomesh) in the treatment of human mandibular Class II furcation defects over a period of 12 months. Thirty patients with chronic periodontitis and a single Class II furcation defect on the buccal or lingual surface of mandibular teeth were included. The clinical parameters evaluated were probing pocket depth (PPD), horizontal probing depth (HPD), vertical relative attachment level (V-RAL), and relative gingival margin level (RGML). three groups were created based on treatment method: EMD + BG + guided tissue regeneration (GTR), BG + GTR, and open flap debridement (OFD). All three groups showed a statistically significant PPD reduction of 1.74 ± 1.00 mm, 0.81 ± 0.31 mm, and 0.46 ± 0.52 mm at 12 months postsurgery. EMD + BG + GTR showed a significantly greater PPD reduction compared with BG + GTR, as well as OFD. EMD + BG + GTR showed a statistically significant vertical clinical attachment gain of 2.12 ± 1.07 mm at 12 months compared with BG + GTR as well as OFD. Significant reductions in mean HPD were observed for EMD + BG + GTR (2.10 mm) as well as BG + GTR (1.5 mm). The number of Class II furcation defects that closed or converted to Class I was greatest for EMD + BG + GTR. It can be concluded that EMD + BG + GTR resulted in a statistically significant reduction of PPD, V-RAL gain, and a nonsignificantly greater reduction of HPD compared to BG + GTR.

    In a radiation-dominated universe, dark matter kinetically decouples from Standard Model particles when the momentum-transfer rate equals the expansion rate. However, dark matter may kinetically decouple during an early matter-dominated era (EMDE), which occurs when the energy content of the Universe is dominated by either an oscillating scalar field or a semi-stable massive particle before Big Bang Nucleosynthesis. Until now, it has been assumed that kinetic decoupling during an EMDE happens...

    Li, Hongguang; Hu, Yue; Li, Fucai; Meng, Guang

    2017-02-01

    Empirical mode decomposition (EMD) has been extensively studied and widely utilized in various areas. In this paper, order-statistics filters are used to replace the traditional interpolation methods and estimate envelopes of the EMD method. Window size selection criteria are proposed to optimize the processing results. Both simulated and experimental signal are applied to investigate characteristics and effectiveness of the proposed method. The results demonstrate that the envelope estimation procedure provides a tremendous enhancement of the EMD method. In the proposed method, application of the order-statistics filter can simplify the process of estimating envelopes and minimize the end effect of the traditional EMD method. Moreover, sifting stop criterion and window width selection are optimized to improve the decomposition speed and processed results. Hence, the processed method is fast, time efficient and effective, and is named as succinct and fast EMD (SF-EMD) in this paper. An application of multiple fault diagnosis for a rotor test rig verifies its potential in practical engineering.

    Full Text Available Background. The purpose of this study was to evaluate the combination of an enamel matrix derivative (EMD and an osteoconductive bone ceramic (BC in improving bone regeneration. Materials and Methods. Four cylindrical cavities (6×6mm were prepared bilaterally in the mandible in three dogs. The defects were randomly assigned to four different treatments—filled with EMD/BC and covered with a nonresorbable membrane, filled with EMD/BC without membrane, membrane coverage only, or control (left untreated—and healed for 2, 4, or 6 weeks. Harvested specimens were prepared for histologic, histomorphometric, and immunohistochemical analyses. Results. Sites treated with EMD/BC with or without membrane showed more total bone formation and lamellar bone formation than membrane-only and control defects. There were no statistically significant differences in total bone formation between EMD/BC with or without membrane. Conclusion. EMD with BC might improve bone formation in osseous defects more than membrane coverage alone; the use of a membrane had no significant additive effect on total bone formation.

    Full Text Available "nAbstract: The aim of the present study was the histological evaluation of Enamel Matrix Derivative (EMD effectiveness for regeneration of periodontal defects. EMD activates cementum synthesis, PDL and bone during the maturation stage of follicole. In this research, EMD was used in surgical defects of premolar teeth in four adult sheep. Muccoperiosteal flap was reflected in buccal site of teeth. The buccal bone plate was removed from mesial to distal in 4 mm depth. After eliminating the cementum by bur and its etching, EMD was applied on exposed dentine and flap was sutured. In opposite sites of those teeth (control sites the same process was performed without etching. After 100 days, sheep were sacrificed and histological study through light microscopic was performed on black sections of operation sites. The results showed that in test sites, regeneration of cementum and bone was 62/5% and 42/5-50% respectively. But in control sites regeneration of cementum and bone was 37.5% and 32/5-42/5% respectively. Also the migration of junctional epithelium in control sites was 8-10% more than test sites. The important point is that in test sites, cementum was completely attached to undermining dentine. But, in control sites, the gap between cementum and dentine was visible. As a result, this study suggests that EMD promotes periodontal regeneration, and EMD application is a successful achievement in regenerative periodontal therapy.

    Full Text Available Extramedullary disease (EMD in multiple myeloma (MM patients is an uncommon event and more attention was directed toward the feature of these patients. Cytogenetic aberration is an important characteristic of MM and is associated with patients’ outcome. In this study, we aimed to compare the cytogenetic abnormality of patients with and without extramedullary manifestation, and to analyze the clinical outcomes of novel agents in EMD patients. We retrospectively investigated data from 41 MM patients. Our analyses showed del(17p13 in 31% of EMD versus 13% of medullary disease (P=0.03 and amp(1q21 in 55% versus 32% (P=0.019. No differences were shown in del(13q14 and t(4;14. 24/27 patients with EMD at diagnosis responded to the novel agents-containing regimens. However, when relapsed, 70% of patients did not benefit from the sequential use of novel agents as salvage therapy. In 14 patients who developed EMD at relapse phase, only 2 patients responded to novel agents therapy. Median overall survival of patients with extramedullary manifestations was 30 months, in comparison to 104 months for patients without EMD (P=0.002. Patients with extramedullary manifestation bore high incidence of poor cytogenetic aberration and novel agents resistance.

    Full Text Available Abstract Background Extracellular matrix proteins are key factors that influence the regenerative capacity of tissues. The objective of the present study was to evaluate the effects of enamel matrix derivative (EMD, TGF-β1, and the combination of both factors (EMD+TGF-β1 on human osteoblastic cell cultures. Methods Cells were obtained from alveolar bone of three adult patients using enzymatic digestion. Effects of EMD, TGF-β1, or a combination of both were analyzed on cell proliferation, bone sialoprotein (BSP, osteopontin (OPN and alkaline phosphatase (ALP immunodetection, total protein synthesis, ALP activity and bone-like nodule formation. Results All treatments significantly increased cell proliferation compared to the control group at 24 h and 4 days. At day 7, EMD group showed higher cell proliferation compared to TGF-β1, EMD + TGF-β1 and the control group. OPN was detected in the majority of the cells for all groups, whereas fluorescence intensities for ALP labeling were greater in the control than in treated groups; BSP was not detected in all groups. All treatments decreased ALP levels at 7 and 14 days and bone-like nodule formation at 21 days compared to the control group. Conclusions The exposure of human osteoblastic cells to EMD, TGF-β1 and the combination of factors in vitro supports the development of a less differentiated phenotype, with enhanced proliferative activity and total cell number, and reduced ALP activity levels and matrix mineralization.

    Seismic P phase arrival picking of weak events is a difficult problem in seismology. The algorithm proposed in this research is based on Empirical Mode Decomposition (EMD) and on the Akaike Information Criterion (AIC) picker. It has been called the EMD-AIC picker. The EMD is a self-adaptive signal decomposition method that not only improves Signal to Noise Ratio (SNR) but also retains P phase arrival information. Then, P phase arrival picking has been determined by applying the AIC picker to the selected main Intrinsic Mode Functions (IMFs). The performance of the EMD-AIC picker has been evaluated on the basis of 1938 micro-seismic signals from the Yongshaba mine (China). The P phases identified by this algorithm have been compared with manual pickings. The evaluation results confirm that the EMD-AIC pickings are highly accurate for the majority of the micro-seismograms. Moreover, the pickings are independent of the kind of noise. Finally, the results obtained by this algorithm have been compared to the wavelet based Discrete Wavelet Transform (DWT)-AIC pickings. This comparison has demonstrated that the EMD-AIC picking method has a better picking accuracy than the DWT-AIC picking method, thus showing this method's reliability and potential.

    The purpose of this study was to compare the clinical and radiographic success rates of two different pulpotomy agents: one novel agent, the biologically active odontogenic protein enamel matrix derivative (EMD) versus formocresol (FC). A randomized, single-blind, split-mouth study was used with a sample of 15 children aged 4 to 7 years (mean age, 5 +/- 0.73 years). A total of 15 pairs of teeth, 1 pair per child, were selected for treatment. One tooth from each pair was randomly assigned to either the EMD pulpotomy group or the FC pulpotomy group. All teeth were followed up clinically and radiographically at 2, 4, and 6 months. After 6 months, the clinical success rates for the FC and EMD groups were 67% and 93%, respectively. Although most likely clinically relevant, the clinical success rate difference after 6 months was not statistically significant. After 6 months, the radiographic success rates for the FC and EMD groups were 13% and 60 %, respectively. There was a statistically significant difference at p < or = 0.05. The clinical and radiographic assessment of EMD pulpotomized teeth in this study offers preliminary evidence that EMD is a promising material which may be as successful, or more so, than other pulpotomy agents.

    Full Text Available What has been undertaken in the present study is the exploration of Caryl Churchill’s selected drama Cloud Nine(1978 with an eye to Judith Butler’s theorizations in regard to “gender performativity”.  According to Judith Butler, gender identity is a socio-political construction that achieves legitimacy and naturality via perpetual observation, repetition and “a stylized repetition of acts”. This stylized repetition of acts along with continuous surveillance, observation and correction leads to the construction of gender identity. In Cloud Nine (1978,we witness how Caryl Churchill(1938- , who occupies a lofty position in the world of theater due to her theatrical expertise, realizes Butler’s conviction and vividly portrays the stylization of gender identity under the sovereignty and hegemony of  phallocentrism and heterosexuality. Key Words: Caryl Churchill, Judith Butler, Cloud Nine, stylization of gendered identity, surveillance, correction

    2014-01-01

    Full Text Available Background: Tissue engineering represents very exciting advances in regenerative medicine; however, periodontal literature only contains few reports. Emdogain (EMD consists of functional molecules that have shown many advantages in regenerative treatments. This study investigated EMD effect on gingival fibroblast adhesion to different membranes. Materials and Methods: Two dense polytetrafluoroethylene membranes (GBR-200, TXT-200, Alloderm and a collagenous membrane (RTM Collagen were used in this experimental study. Each membrane was cut into four pieces and placed at the bottom of a well in a 48-well plate. 10 μg/mL of EMD was added to two wells of each group.Two wells were left EMD free. Gingival fibroblasts were seeded to all the wells. Cell adhesion was evaluated by means of a Field Emission Scanning Electron Microscope after 24 hours incubation. Data was analyzed by independent t-test, one-way and two-way ANOVA and post hoc LSD test. P < 0.05 in independent t-test analysis and P < 0.001 in one-way ANOVA, two-way ANOVA and post hoc LSD analysis was considered statistically significant. Results: Alloderm had the highest cell adhesion capacity in EMD+ group and the difference was statistically significant (P < 0.001. In EMD- group, cell adhesion to TXT-200 and Alloderm was significantly higher than GBR-200 and collagenous membrane (P < 0.001. Conclusion: This study showed that EMD may decrease the cell adhesion efficacy of GBR-200, TXT-200 and collagenous membrane but it can promote this efficacy in Alloderm. It also showed the composition of biomaterials, their surface textures and internal structures can play an important role in their cell adhesion efficacy.

  12. A Novel Denoising Method for an Acoustic-Based System through Empirical Mode Decomposition and an Improved Fruit Fly Optimization Algorithm

    Directory of Open Access Journals (Sweden)

    Jing Xu

    2017-02-01

    Full Text Available Generally, the sound signal produced by transmission unit or cutting unit contains abundant information about the working state of a machine. The acoustic-based diagnosis system presents some distinct advantages in some severe conditions particularly due to its unique non-contact measurement and unlimited use at the installation site. However, the original acoustic signal collected from manufacture process is always polluted by various background noises. In order to eliminate noise components from machinery sound effectively, an empirical mode decomposition (EMD threshold denoising method optimized by an improved fruit fly optimization algorithm (IFOA is launched in this paper. The acoustic signal was first decomposed by the adaptive EMD to obtain a series of intrinsic mode functions (IMFs. Then, the soft threshold function was applied to shrink the IMF coefficients. While the threshold of each IMF was determined by statistical estimation and empirical value for traditional EMD denoising, the denoising effect was often not desired and time-consuming. To solve these disadvantages, fruit fly optimization algorithm (FOA was introduced to search global optimal threshold of each IMF. Moreover, to enhance the group diversity during production of the next generation of fruit flies and balance the local and global searching ability, a variation coefficient and a disturbance coefficient was introduced to the basic FOA. Then, a piece of simulated acoustic signal produced by the train was applied to validate the proposed EMD and IFOA threshold denoising (EMD-IFOA. The simulation results, which decreased 35.40% and 18.92% in mean squared error (MSE and percent root mean square difference (PRD respectively, and increased 40.36% in signal-to-noise ratio improvement (SNRimp compared with basic EMD denoising scheme at SNR = 5 dB, illustrated the effectiveness and superiority of the proposed approach. Finally, the proposed EMD-IFOA was conducted on an actual

    2006-02-01

    The aim of the present study was to evaluate the efficiency of Emdogain (EMD) in preserving the size of the periodontal ligament progenitor pool (clonogenic capacity) and in promoting their proliferation. Periodontal ligament fibroblasts (PDLF) were obtained from explants of young permanent healthy tooth. After initial outgrowth (10 days to 2 weeks following explantation), the culture medium of experimental flasks was replaced with medium supplemented with 100 microg ml(-1) EMD, whereas the other served as controls and were fed with regular medium. Following 5 weeks, the cells were washed (3x), harvested (trypsin + EDTA), and evaluated for their viability. Viable cells from each group were inoculated into six 96-well plates at a concentration of one viable cell per two wells and were allowed to grow for 5 weeks. The percentage of cells with clonogenic capacity was determined as the number of colonies formed/number of cells seeded x 100 in the experimental and control groups. Three degrees of dish area coverage were utilized: up to 25%, between 25% and 75% and higher than 75%. This experiment was repeated four times from four different donors. A total of 2328 cells were evaluated, half of which, were cultured with EMD. The mean percentage of cells (from all donors) who exhibited any clonogenic capacity in the presence of EMD was comparable with that of cells cultured in the absence of EMD: 26.6 +/- 14.3% when compared with 34.6 +/- 20.6% respectively (P = 0.186). Similarly, the percentage of clones that proliferated to cover up to 25% of the well area was comparable in the two groups 7.5 +/- 8.6 for EMD-treated clones and 7.1 +/- 7.8 for untreated clones (P = 0.674). The percentage of clones that proliferated to cover 25% up to 75% of the well area was greater EMD-treated clones as compared with the untreated cells: 8.1 +/- 6.7% vs 3.8 +/- 3%. However this difference was not statistically significant (P = 0.277). In contrast, the percentage of clones that covered

    2008-01-01

    The electromagnetic mass damper (EMD) control system, as an innovative active control system to reducestructural vibration, offers many advantages over traditional active mass driver/damper (AMD) control systems. In this paper,studies of several EMD control strategies and bench-scale shaking table tests of a two-story model structure are described.First, two structural models corresponding to uncontrolled and Zeroed cases are developed, and parameters of these modelsare validated through sinusoidal sweep tests to provide a basis for establishing an accurate mathematical model for furtherstudies. Then, a simplified control strategy for the EMD system based on the pole assignment control algorithm is proposed.Moreover, ideal pole locations are derived and validated through a series of shaking table tests. Finally, three benchmarkearthquake ground motions and sinusoidal sweep waves are imposed onto the structure to investigate the effectiveness andfeasibility of using this type of innovative active control system for structural vibration control. In addition, the robustnessof the EMD system is examined. The test results show that the EMD system is an effective and robust system for the controlof structural vibrations.

  15. The inner structure of empirical mode decomposition

    Wang, Yung-Hung; Young, Hsu-Wen Vincent; Lo, Men-Tzung

    2016-11-01

    The empirical mode decomposition (EMD) is a nonlinear method that is truly adaptive with good localization property in the time domain for analyzing non-stationary complex data. The EMD has been proven useful in a wide range of applications. However, due to the nonlinear and complex nature of the sifting process, the most essential step of the EMD, a firm mathematical foundation or a transparent physical description are still lacked for EMD. Here, we embark on constructing a mathematical theory of the sifting operator. We first show that the sifting operator can be expressed as the data plus the sum of the responses to the impulses (multiplied by the data value) at the extrema. Such an expression of the sifting operator is then used to investigate the adaptive nature and the localizing effect of the EMD. Alternatively, the sifting operator can also be represented by a sifting matrix, which depends nonlinearly on the extrema distribution. Based on the eigen-decomposition of the sifting matrix, the transfer function of the sifting process is analyzed. Finally we answer what an intrinsic mode function (IMF) is from the wave perspective by exploring the physical basis of the IMFs.

  16. GPR Signal Denoising and Target Extraction With the CEEMD Method

    KAUST Repository

    Li, Jing

    2015-04-17

    In this letter, we apply a time and frequency analysis method based on the complete ensemble empirical mode decomposition (CEEMD) method in ground-penetrating radar (GPR) signal processing. It decomposes the GPR signal into a sum of oscillatory components, with guaranteed positive and smoothly varying instantaneous frequencies. The key idea of this method relies on averaging the modes obtained by empirical mode decomposition (EMD) applied to several realizations of Gaussian white noise added to the original signal. It can solve the mode-mixing problem in the EMD method and improve the resolution of ensemble EMD (EEMD) when the signal has a low signal-to-noise ratio. First, we analyze the difference between the basic theory of EMD, EEMD, and CEEMD. Then, we compare the time and frequency analysis with Hilbert-Huang transform to test the results of different methods. The synthetic and real GPR data demonstrate that CEEMD promises higher spectral-spatial resolution than the other two EMD methods in GPR signal denoising and target extraction. Its decomposition is complete, with a numerically negligible error.

  17. Nanoflake Manganese Oxide and Nickel-Manganese Oxide Synthesized by Electrodeposition for Electrochemical Capacitor

    Directory of Open Access Journals (Sweden)

    Man Van Tran

    2015-01-01

    Full Text Available Nanoflake structures of electrochemical manganese oxide (EMD and nickel mixed manganese oxide (NiMD were directly deposited on a stainless steel by using Chronoamperometry and Cyclic Voltammetry (CV techniques. The structure, morphology, and capacitive behavior of EMD or NIMD nanoflake were affected by the electrodeposition modes and deposition time. The highest specific capacitance (Csp was obtained for only two-minute deposition by both methods. EMD nanoflakes electrodeposited by CV technique show higher specific capacitance values than those prepared by Chronoamperometry owing to its homogenous and highly porous surface. All EMD samples exhibited excellent cycle behavior, less than 5% capacitance loss after 1000 cycles. Ni mixed MnO2 was prepared at different Mn2+/Ni2+ ratios for 2 minutes of electrodeposition. The presence of Ni2+ ion enhanced the Csp value at high charge-discharge rate due to the decrease of the charge transfer resistance. The supercapacitor prototype of 2 cm × 2 cm was assembled using EMD and NiMD as electrode material and tested at 1 A·g−1.

  18. Understanding emergency medical dispatch in terms of distributed cognition: a case study.

    Science.gov (United States)

    Furniss, Dominic; Blandford, Ann

    Emergency medical dispatch (EMD) is typically a team activity, requiring fluid coordination and communication between team members. Such working situations have often been described in terms of distributed cognition (DC), a framework for understanding team working. DC takes account of factors such as shared representations and artefacts to support reasoning about team working. Although the language of DC has been developed over several years, little attention has been paid to developing a methodology or reusable representation which supports reasoning about an interactive system from a DC perspective. We present a case study in which we developed a method for constructing a DC account of team working in the domain of EMD, focusing on the use of the method for describing an existing EMD work system, identifying sources of weakness in that system, and reasoning about the likely consequences of redesign of the system. The resulting DC descriptions have yielded new insights into the design of EMD work and of tools to support that work within a large EMD centre.

    The major problem with the empirical mode decomposition (EMD) algorithm is its lack of a theoretical framework. So, it is difficult to characterize and evaluate this approach. In this paper, we propose, in the 2-D case, the use of an alternative implementation to the algorithmic definition of the so-called "sifting process" used in the original Huang's EMD method. This approach, especially based on partial differential equations (PDEs), was presented by Niang in previous works, in 2005 and 2007, and relies on a nonlinear diffusion-based filtering process to solve the mean envelope estimation problem. In the 1-D case, the efficiency of the PDE-based method, compared to the original EMD algorithmic version, was also illustrated in a recent paper. Recently, several 2-D extensions of the EMD method have been proposed. Despite some effort, 2-D versions for EMD appear poorly performing and are very time consuming. So in this paper, an extension to the 2-D space of the PDE-based approach is extensively described. This approach has been applied in cases of both signal and image decomposition. The obtained results confirm the usefulness of the new PDE-based sifting process for the decomposition of various kinds of data. Some results have been provided in the case of image decomposition. The effectiveness of the approach encourages its use in a number of signal and image applications such as denoising, detrending, or texture analysis.
