    Barbary, Kyle

    2016-03-01

    Astronomers love Python because it is open source, easy to learn, and has a tremendous ecosystem for scientific computing. The Julia programming language has many of those same characteristics. In this talk, I'll discuss the use of Julia in astronomy and the growing ecosystem of astronomy packages, particularly those managed by the JuliaAstro organization (http://JuliaAstro.github.io). Most importantly, I will highlight some areas ripe for collaboration between Python and Julia developers in astronomy.

  12. Wave equation modelling using Julia programming language

    Science.gov (United States)

    Kim, Ahreum; Ryu, Donghyun; Ha, Wansoo

    2016-04-01

    Julia is a young high-performance dynamic programming language for scientific computations. It provides an extensive mathematical function library, a clean syntax and its own parallel execution model. We developed 2d wave equation modeling programs using Julia and C programming languages and compared their performance. We used the same modeling algorithm for the two modeling programs. We used Julia version 0.3.9 in this comparison. We declared data type of function arguments and used inbounds macro in the Julia program. Numerical results showed that the C programs compiled with Intel and GNU compilers were faster than Julia program, about 18% and 7%, respectively. Taking the simplicity of dynamic programming language into consideration, Julia can be a novel alternative of existing statically typed programming languages.

  13. Entire functions whose Julia sets include any finitely many copies of quadratic Julia sets

    Katagata, Koh

    2017-06-01

    We prove that for any finite collection of quadratic Julia sets, a polynomial and a transcendental entire function exist whose Julia sets include copies of the given quadratic Julia sets. In order to prove the result, we construct quasiregular maps with required dynamics and employ the quasiconformal surgery to obtain the desired functions.

    We prove that wandering components of the Julia set of a polynomial are singletons provided each critical point in a wandering Julia component is non-recurrent. This means a conjecture of Branner-Hubbard is true for this kind of polynomials.

  15. The Nullness Analyser of julia

    Science.gov (United States)

    Spoto, Fausto

    This experimental paper describes the implementation and evaluation of a static nullness analyser for single-threaded Java and Java bytecode programs, built inside the julia tool. Nullness analysis determines, at compile-time, those program points where the null value might be dereferenced, leading to a run-time exception. In order to improve the quality of software, it is important to prove that such situation does not occur. Our analyser is based on a denotational abstract interpretation of Java bytecode through Boolean logical formulas, strengthened with a set of denotational and constraint-based supporting analyses for locally non-null fields and full arrays and collections. The complete integration of all such analyses results in a correct system of very high precision whose time of analysis remains in the order of minutes, as we show with some examples of analysis of large software.

    Full Text Available In her recent writings on the powers and limits of psychoanalysis, Julia Kristeva develops a theory of power and subjectivity that engages implicitly, if not explicitly, with biopolitical themes. Exploring these engagements, this paper draws on Kristeva to discuss the mute symptoms of homo sacer and the regulatory power of the spectacle. Staging an uncommon (and sometimes antagonistic conversation between Kristeva, Agamben, and Foucault, I construct a field of inquiry that I term the “psychic life of biopolitics.”

    In this paper, we investigate elliptic functions of the form fΛ = 1/(1 + (℘Λ)2), where ℘Λ is the Weierstrass elliptic function on a real rhombic lattice. We show that a typical function in this family has a superattracting fixed point at the origin and five other equivalence classes of critical points. We investigate conditions on the lattice which guarantee that fΛ has a double toral band, and we show that this family contains the first known examples of elliptic functions for which the Julia set is disconnected but not Cantor.

    We investigate the set of biaccessible points for connected polynomial Julia sets of arbitrary degrees $d\\geq 2$. We prove that the Hausdorff dimension of the set of external angles corresponding to biaccessible points is less than 1, unless the Julia set is an interval. This strengthens theorems of Stanislav Smirnov and Anna Zdunik: they proved that the same set of external angles has zero 1-dimensional measure.

  18. Lee Wick Dark Energy

    CERN Document Server

    Lee, Seokcheon

    2008-01-01

    We consider the cosmological application of Lee-Wick theory where a field has a higher derivative kinetic operators. The higher derivative term can be eliminated by introducing a set of auxiliary fields. We investigate the cosmological evolutions of these fields as a candidate of dark energy. This model has the same structure as so called ``quintom' model except the form of potentials and the sign of the slope of the potentials. This model can give the stable late time phantom dominated scaling solution ($\\omega_{\\DE} < -1$) or tracking attractors ($\\omega_{\\DE} = 0$) depending on the choice of the slopes of the potential. In order to be a viable dark energy candidate, the present energy density contrast of dark energy ($\\Omega_{\\DE}^{(0)}$) should be close to an observed value (0.73) at the same time. However, a simple toy model of the theory can not satisfy both $\\omega_{\\DE}^{(0)} \\simeq -1$ and $\\Omega_{\\DE}^{(0)} = 0.73$. This is also true for any quintom model in literatures unless we suffer from the...

  1. An image encryption algorithm utilizing julia sets and hilbert curves.

    Science.gov (United States)

    Sun, Yuanyuan; Chen, Lina; Xu, Rudan; Kong, Ruiqing

    2014-01-01

    Image encryption is an important and effective technique to protect image security. In this paper, a novel image encryption algorithm combining Julia sets and Hilbert curves is proposed. The algorithm utilizes Julia sets' parameters to generate a random sequence as the initial keys and gets the final encryption keys by scrambling the initial keys through the Hilbert curve. The final cipher image is obtained by modulo arithmetic and diffuse operation. In this method, it needs only a few parameters for the key generation, which greatly reduces the storage space. Moreover, because of the Julia sets' properties, such as infiniteness and chaotic characteristics, the keys have high sensitivity even to a tiny perturbation. The experimental results indicate that the algorithm has large key space, good statistical property, high sensitivity for the keys, and effective resistance to the chosen-plaintext attack.

    We show that, if the Julia set of a transcendental entire function is locally connected, then it takes the form of a spider's web in the sense defined by Rippon and Stallard. In the opposite direction, we prove that a spider's web Julia set is always locally connected at a dense subset of buried points. We also show that the set of buried points (the residual Julia set) can be a spider's web.

Diferentes definições de fractais surgiram com o aprimoramento de sua teoria. Sem rigor matemático pode-se definir fractais como objetos que apresentam auto-semelhança, ou seja, um fractal é um objeto cuja geometria se repete infinitamente em porções menores, semelhantes ao próprio objeto. Existem diversos tipos de fractais, mas apresentaremos as figuras geradas a partir de iterações de funções. Porém para chegar às figuras fractais, precisaremos falar em iterações de funções complexas, que associam a um ponto complexo $a+bi$ uma imagem complexa $f(a+bi = c+di$. O conjunto de Julia é conhecido como o conjunto que separa o plano complexo em dois conjuntos, o primeiro formado pelos pontos cujas órbitas tendem a origem e o segundo formado pelos pontos cujas órbitas tendem ao ponto no infinito. Os pontos do conjunto de Mandelbrot nos fornecem conjuntos de Julia conexos e os pontos que não estão no conjunto de Mandelbrot correspondem a conjuntos de Julia desconexos. Conjuntos de Julia e de Mandelbrot são de geometria fractal e neste artigo são discutidos a dinâmica da função quadrática complexa $f(z=z^2+c$}.

    Keller, Karsten

    2000-01-01

    This book is mainly devoted to the combinatorics of quadratic holomorphic dynamics. The conceptual kernel is a self-contained abstract counterpart of connected quadratic Julia sets which is built on Thurston's concept of a quadratic invariant lamination and on symbolic descriptions of the angle-doubling map. The theory obtained is illustrated in the complex plane. It is used to give rigorous proofs of some well-known and some partially new statements on the structure of the Mandelbrot set. The text is intended for graduate students and researchers. Some elementary knowledge in topology and in functions of one complex variable is assumed.

    2016-01-01

    We derive and study an approximate static vacuum solution generated by a point-like source in a higher derivative gravitational theory with a pair of complex conjugate ghosts. The gravitational theory is local and characterized by a high derivative operator compatible with Lee-Wick unitarity. In particular, the tree-level two-point function only shows a pair of complex conjugate poles besides the massless spin two graviton. We show that singularity-free black holes exist when the mass of the source $M$ exceeds a critical value $M_{\\rm crit}$. For $M > M_{\\rm crit}$ the spacetime structure is characterized by an outer event horizon and an inner Cauchy horizon, while for $M = M_{\\rm crit}$ we have an extremal black hole with vanishing Hawking temperature. The evaporation process leads to a remnant that approaches the zero-temperature extremal black hole state in an infinite amount of time.

  12. Generalization of 3D Mandelbrot and Julia sets

    Institute of Scientific and Technical Information of China (English)

    CHENG Jin; TAN Jian-rong

    2007-01-01

    In order to further enrich the form of 3D Mandelbrot and Julia sets, this paper first presents two methods of generating3D fractal sets by utilizing discrete modifications of the standard quaternion algebra and analyzes the limitations in them. To overcome these limitations, a novel method for generating 3D fractal sets based on a 3D number system named ternary algebra is proposed. Both theoretical analyses and experimental results demonstrate that the ternary-algebra-based method is superior to any one of the quad-algebra-based methods, including the first two methods presented in this paper, because it is more intuitive, less time consuming and can completely control the geometric structure of the resulting sets. A ray-casting algorithm based on period checking is developed with the goal of obtaining high-quality fractal images and is used to render all the fractal sets generated in our experiments. It is hoped that the investigations conducted in this paper would result in new perspectives for the generalization of3D Mandelbrot and Julia sets and for the generation of other deterministic 3D fractals as well.

  13. First OH reactivity measurements in Harvard Forest

    Herdlinger-Blatt, I. S.; Martin, S. T.; Hansel, A.; McKinney, K. A.

    2013-12-01

    The OH reactivity provides critical insight into the HOx budget under actual atmospheric conditions, and has implications for the production of ozone and the formation of secondary organic material. Previous studies have indicated that the OH reactivity measured at field sites often exceeds model estimations, but current experiments remain inconclusive about the origin of the discrepancy between the modeled and measured OH reactivity (Lou et al., 2010). As of now there are only a limited number of atmospheric studies of total OH reactivity available, so to improve understanding of the OH reactivity more studies are needed. The first OH reactivity measurements in the northeastern United States are being performed during the summer of 2013 at Harvard Forest. Harvard forest, is located about 100 km west of the Boston metropolitan area, is one of the most intensively studied forests in North America. The main biogenic VOC emitted from Harvard Forest is isoprene followed by monoterpenes and methanol. Sampling for the OH reactivity measurements will be conducted from a 30m tall meteorological tower at the Harvard Forest site. The air is drawn into a reaction cell where the OH reactivity is determined using the Comparative Reactivity Method (Sinha et al., 2008) employing a High-Sensitivity Proton Transfer Reaction Mass Spectrometer (Lindinger et al., 1998, Hansel et al., 1998). In addition to the OH reactivity measurements, the most abundant compounds present in the air sample will be quantified using PTR-MS. The quantification of these compounds is needed to compare the theoretical calculated OH reactivity with the measured OH reactivity data. The measurements will be used to evaluate our understanding of the OH budget at Harvard Forest. References: A. Hansel, A. Jordan, C. Warneke, R. Holzinger, and W.

  14. Julia Rush's diary: coping with loss in the early nineteenth century.

    Science.gov (United States)

    Thielman, S B; Melges, F T

    1986-09-01

    Julia Rush (1759-1848), wife of Benjamin Rush (1745-1813), recorded her thoughts over a 33-year period in an unpublished devotional journal. Many of the entries relate to her experience of the loss of Benjamin Rush. Although the diary is inadequate as a source of understanding psychodynamic processes at work, it provides considerable information about Julia Rush's coping behavior. An analysis of this journal reveals that she used three major coping strategies to deal with the loss of her husband: ritualized language, time marking, and cognitive reframing. These devotional meditations also illuminate the way early nineteenth-century religious views shaped Julia Rush's response to loss.

    Huang, Chao-Shang; Li, Tianjun; Liao, Wei; Zhu, Shou-Hua

    2008-07-01

    We study the possible origin of Friedberg-Lee symmetry. First, we propose the generalized Friedberg-Lee symmetry in the potential by including the scalar fields in the field transformations, which can be broken down to the Friedberg-Lee symmetry spontaneously. We show that the generalized Friedberg-Lee symmetry allows a typical form of Yukawa couplings, and the realistic neutrino masses and mixings can be generated via the seesaw mechanism. If the right-handed neutrinos transform nontrivially under the generalized Friedberg-Lee symmetry, we can have the testable TeV scale seesaw mechanism. Second, we present two models with the SO(3)×U(1) global flavor symmetry in the lepton sector. After the flavor symmetry breaking, we can obtain the charged lepton masses, and explain the neutrino masses and mixings via the seesaw mechanism. Interestingly, the complete neutrino mass matrices are similar to those of the above models with generalized Friedberg-Lee symmetry. So the Friedberg-Lee symmetry is the residual symmetry in the neutrino mass matrix after the SO(3)×U(1) flavor symmetry breaking.

    Directory of Open Access Journals (Sweden)

    M. A. Alia

    2007-01-01

    Full Text Available This paper describes a new cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Having fractal based digital signature scheme is possible due to the strong connection between the Mandelbrot and Julia fractal sets. The link between the two fractal sets used for the conversion of the private key to the public key. Mandelbrot fractal function takes the chosen private key as the input parameter and generates the corresponding public-key. Julia fractal function then used to sign the message with receiver's public key and verify the received message based on the receiver's private key. The propose scheme was resistant against attacks, utilizes small key size and performs comparatively faster than the existing DSA, RSA digital signature scheme. Fractal digital signature scheme was an attractive alternative to the traditional number theory digital signature scheme.

    Astola, Helena; Tabus, Ioan

    2016-01-01

    Based on an invariance-type property of the Lee-compositions of a linear Lee code, additional equality constraints can be introduced to the linear programming problem of linear Lee codes. In this paper, we formulate this property in terms of an action of the multiplicative group of the field [Formula: see text] on the set of Lee-compositions. We show some useful properties of certain sums of Lee-numbers, which are the eigenvalues of the Lee association scheme, appearing in the linear programming problem of linear Lee codes. Using the additional equality constraints, we formulate the linear programming problem of linear Lee codes in a very compact form, leading to a fast execution, which allows to efficiently compute the bounds for large parameter values of the linear codes.

Researchers have long assumed that above and belowground phenology is synchronous; for example, most parameterizations of belowground carbon allocation in terrestrial biosphere models are based on allometry and represent a fixed fraction of net C uptake. However, using results from metaanalysis as well as empirical data from oak and hemlock stands at Harvard Forest, we show that synchronous root and shoot growth is the exception rather than the rule. We collected root and shoot phenology measurements from studies across four biomes (boreal, temperate, Mediterranean, and subtropical). General patterns of root phenology varied widely with 1-5 production peaks in a growing season. Surprisingly, in 9 out of the 15 studies, the first root production peak was not the largest peak. In the majority of cases maximum shoot production occurred before root production (Offset>0 in 32 out of 47 plant sample means). The number of days offset between maximum root and shoot growth was negatively correlated with median annual temperature and therefore differs significantly across biomes (ANOVA, F3,43=9.47, pGrowth form (woody or herbaceous) also influenced the relative timing of root and shoot growth. Woody plants had a larger range of days between root and shoot growth peaks as well as a greater number of growth peaks. To explore the range of phenological relationships within woody plants in the temperate biome, we focused on above and belowground phenology in two common northeastern tree species, Quercus rubra and Tsuga canadensis. Greenness index, rate of stem growth, root production and nonstructural carbohydrate content were measured beginning in April 2012 through August 2013 at the Harvard Forest in Petersham, MA, USA. Greenness and stem growth were highest in late May and early June with one clear

    Araki, Takeshi; Geng, C. Q.

    We consider the µ - τ symmetric Friedberg-Lee (FL) symmetry for the neutrino sector and show that a specific FL translation leads to the tribimaximal mixing pattern of the Maki-Nakagawa-Sakata (MNS) matrix. We also apply the symmetry to the type-I seesaw framework and address the baryon asymmetry of the universe through the leptogenesis mechanism. We try to establish a relation between the net baryon asymmetry and CP phases included in the MNS matrix.

    The Yang-Lee zeros of an antiferromagnetic Heisenberg ladder model are determined. It is found that if J4≤0 Yang-Lee zeros are located on the unit circle and on the negative real axis in the complex activity plane. In particular, if J4≤0 and 2J2≥J4, Yang-Lee zeros are located on the unit circle and the Yang-Lee circle theorem is valid. If J4 > 0, Yang-Lee zeros are located on some complicated curves.

  13. The causes of the Roman civil war, 49 B.C.: Julia and Crassus

    Directory of Open Access Journals (Sweden)

    A. P. Koval

    2016-03-01

    Full Text Available The title of the article is ‘The Causes of the Roman Civil War, 49 B.C.: Julia and Crassus’. The purpose of the article was to examine the theory, provided by ancient writers, according to which deaths of Julia and Marcus Licinius Crassus are interpreted as one of the causes of the Roman Civil war in 49 B.C. This theory wasn’t an object of the special research and many modern scholars take on trust accounts of the ancient writers, following Mommsen’s view. According to the sources, Julia was the «pledge of consent» between Pompey and Caesar, while Crassus was their mediator. In contrast, E. Gruen believed, that the deaths of Julia and Crassus had not been so ruinous for relations of Pompey and Caesar. For example, Julia had died in 54 B.C., but the Civil war started in 49 B.C. – according to the sources, it should have been started immediately after Julia’s death. The study tested, that the main source of such interpretation of Julia’s and Crassus’ deaths was Lucan’s ‘Pharsalia’. Such characterization of those is the most full in his poem. Textual analysis proves, that Lucan’s poem was a source of this theory for many other ancient writers. For example, Plutarch’s and Appian’s characterizations of Julia and Crassus are the same, as in ‘Pharsalia’, considering the translation from Latin to Greek. Further examination established that Lucan was the main propagandist of such characterization, but he wasn’t its author. Julia was described as the «pledge of consent» in writings of Velleius Paterculus and Valerius Maximus that had been written in a few decades before ‘Pharsalia’. However, there is no such characterization in writings of Cicero and Livius, who were the eyewitnesses of the Civil war. As a result, it was concluded, that such characterization had been formed among Roman writers of the early principate and retailed by Lucan. As a conclusion it must be emphasized, that close study of the ancient

    Bennett, K.

    2012-12-01

    As part of the Long Term Ecological Research (LTER) program, the Harvard Forest in Petersham, Massachusetts seeks to train the next generation of researchers, by involving K-12 grade students and their teachers in hands-on, field-based, ecological research in their own schoolyard and community. Students learn to collect data on important long-term ecological issues and processes. Student data are then shared on the Harvard Forest website. To prepare teachers for project protocols, teachers are given direct access to Harvard ecologists with professional development workshops and on-line resources. With the Harvard Forest Schoolyard LTER program, students can participate in three different research projects focusing on phenology, invasive insects, and vernal pools. Teachers attend the Summer Institute for Teachers to learn project content and methods. They return in fall to participate in one of three levels of data workshops to learn how to input, manage, and analyze project data. In the spring, teachers again meet with the Harvard ecologists about project protocols, and to share, through a series of teacher presentations, the ways these project themes are being integrated into class curricula. These professional development opportunities result in long term collaborative partnerships with local schools and the Harvard Forest LTER. In addition to the LTER Schoolyard Ecology Program, the Harvard Forest has supported a successful Research Experience for Teachers (RET) program for the last six years. Throughout the summer, teachers work on research projects alongside Harvard Forest and affiliated scientists, post-docs, graduate students, and REU's (Research Experience for Undergraduates). The RET program provides teachers with the opportunity to build scientific knowledge, develop an understanding of research methods, and translate their new knowledge and experiences into cutting edge classroom lessons. The past two summers I have worked with Dr. Andrew Richardson

    How did Pierre Fatou and Gaston Julia create what we now call Complex Dynamics, in the context of the early twentieth century and especially of the First World War? The book is based partly on new, unpublished sources.Who were Pierre Fatou, Gaston Julia, Paul Montel? New biographical information is given on the little known mathematician that was Pierre Fatou. How did the serious WW1 injury of Julia influence mathematical life in France? From the reviews of the French edition: "Audin’s book is indeed filled with marvelous biographical information and analysis, dealing not just with the men mentioned in the book’s title but a large number of other players, too … . the book under review addresses itself to scholars for whom the history of mathematics has a particular resonance and especially to mathematicians active, or even with merely an interest in, complex dynamics. … presents it all to the reader in a very appealing form."

    The Trading Agent Competition (TAC) is an annual event in which teams from around the world compete in a given scenario concerning the trading agent problem. This paper describes some of the key features and strategies employed by HarTAC, the Harvard University TAC SCM 2003 agent. HarTAC was built to be a moderately aggressive, production-oriented agent, combining a semi-conservative component purchasing strategy with a highly aggressive cycle-based sell side.

  1. Merton as Harvard sociologist: engagement, thematic continuities, and institutional linkages.

    Science.gov (United States)

    Nichols, Lawrence T

    2010-01-01

    In this paper I explore the significance of the initial decade of Robert K. Merton's graduate and professional career, from 1931, when he entered the new doctoral program in sociology at Harvard, until 1939, when he joined the Department of Sociology at Tulane University as an associate professor and acting chairperson. Drawing on archival sources, as well as the professional literature, I examine how Merton engaged the exceptionally rich, interdisciplinary context of Harvard in the 1930s, including both interpersonal networks and diverse intellectual perspectives. In particular, I identify connections between Merton's early writing, "oral publications" and teaching, and three locally developed and dominant paradigms of sociology. Following an assessment of the influence of Merton's works published from 1934 to 1939, I trace continuities between Merton's achievements at Harvard and his subsequent teaching and research at Tulane and Columbia. I conclude that a fuller appreciation of Merton's "less noticed" decade in Cambridge is indispensable for understanding his overall career, and that it clarifies linkages across sociological work at three universities in the mid-twentieth century.

  2. Julia Says’: The Spirit-Writing and Editorial Mediumship of W. T. Stead

    Directory of Open Access Journals (Sweden)

    Sarah Crofton

    2013-04-01

    Full Text Available In his work on Spiritualism, W. T. Stead wrote as both a commentator and a practitioner. In the same office, by the same hand, he penned editorial pieces for his occultist journal and engaged in spirit-writing. Stead claimed to serve as an amanuensis for the spirit of the late Julia Ames and printed her first-person accounts of the nature of life after death in the pages of 'Borderland.'   When he channelled Julia, Stead was following the current zeitgeist of modern Victorian occultism. In the previous half-century, spirit-writing had become firmly established as a key practice of Spiritualism.It was a literary tradition as well as a cultural one. Spirits who manifested through the written word propagated tropes and repeated narratives. One can trace common turns of phrase, philosophies, rhetorical tricks, shared metaphors, and myths of literary production across a broad range of channelled missives through different schools of occultist thought at the 'fin de siècle'. Stead was quick to internalize many of these, and ‘Julia’ was nothing if not solidly generic.   The literary nature of occultism both fuelled and thwarted Stead’s attempts to use the press to legitimize study of the ‘other world’. Stead envisioned 'Borderland' as an open court in which proofs of occultist phenomena could be publicized and judged on their own merits. Building on his wider ideas of the value of periodical literature as an open court (as expressed in his ‘Government by Journalism’, for example, Stead believed that a journal dedicated to collecting and assessing occultist claims would be the first step in a social mission to bridge the communication gap between the living and the dead, and to do so in a way which would render such links demotic and quotidian. Instead, the pages of 'Borderland' quickly filled with anecdotes and ghost stories. The magazine’s editorial authority could draw attention to the familiar tropes and recurring narratives of

  3. ON INTERIOR POINTS OF THE JULIA SET J(R) FOR RANDOM DYNAMICAL SYSTEM R

    The authors consider the random iteration of serval functions. Denote by J(R) the Julia set for the random iteration dynamical system formed by a set of complex functions R ={R1,R2,…, RM}. Some sufficient conditions axe given for J(R) to have no interior points.Also some conditions are given for J(R) to have interior points but fail to be the extendedplane. In addition, J(azn,bzn) (n ≥ 2,ab ≠ O) and J(z2+c1,x2+c2) are investigated and some interesting results are obtained.

  6. Infinitely renormalizable quadratic polynomials with non-locally connected Julia set

    DEFF Research Database (Denmark)

    Sørensen, Dan Erik Krarup

    1997-01-01

    We present two strategies for producing and describing some connected non-locally connected Julia sets of infinitely renormalizable quadratic polynomials. The main idea is to obtain the polynomial as the limit of repeated parabolic perturbations of the satellite type. The basic tool at each step...... is to control the behaviour of certain external rays. We distinguish between perturbations to left and right satellites and investigate the differences between one-sided and two-sided (ie. alternating) parabolic perturbations. In the one-sided case, we prove the existence of polynomials having an explicitly...

    2007-01-01

    On 30 August, Professor T.D. Lee, who received the Nobel Prize for Physics in 1957, gave a seminar at CERN on symmetry and asymmetry in electroweak interactions, 50 years after the discovery of the non-conservation of parity. In 1956, Tsung-Dao Lee postulated with Chen Ning Yang that parity is not conserved in weak interactions, and suggested several experiments to demonstrate this. The following year, an experiment led by Chien-Shiung Wu proved this prediction and, soon after, T.D. Lee and Chen Ning Yang were awarded the Nobel Prize for Physics. Still very active at over 80 years of age, T.D. Lee pursues his theory work to this day.

  12. Fenhexamid adsorption behavior on soil amended with wine lees.

    Science.gov (United States)

    Pinna, Maria Vittoria; Budroni, Marilena; Farris, Giovanni Antonio; Pusino, Alba

    2008-11-26

    The adsorption of fenhexamid (FEN) [N-(2,3-dichloro-4-hydroxyphenyl)-1-methylcyclohexanecarboxamide] on vineyard soil amended with wine lees (WL) produced by vinery was studied. The adsorption extent depends on WL fraction. The addition of the centrifuged solid lees (SWL) increases the FEN adsorption on soil. Most likely, the organic insoluble fraction formed mainly by dead fermentation yeasts is responsible for the observed increase. The adsorption measured on some deactivated yeasts of wine fermentation shows that Saccharomyces cerevisiae are the most active in FEN retention. On the other hand, the soil amendment with whole WL decreases considerably the fungicide adsorption. This opposite effect may be the result of FEN hydrophobic bonds with the dissolved organic matter of lees that keeps fungicide in solution. This hypothesis is substantiated by the increased FEN solubility in the supernatant of centrifuged wine lees (LWL). The results of soil column mobility confirm that the elution with LWL increases the mobility of FEN in soil.

  16. Friedberg-Lee Symmetry for Quark Masses and Flavor Mixing

    CERN Document Server

    Ren, Ping

    2008-01-01

    We point out a generic correlation between the Friedberg-Lee symmetry of quark mass operators and the vanishing of quark masses. We make phenomenological explorations on two textures of quark mass matrices with the broken Friedberg-Lee symmetry. We present a new pattern of quark mass matrices in agreement with current experimental data. Both analytical and numerical results of our calculations are discussed in detail.

    Lee-Wick electrodynamics in the vicinity of a conducting plate is investigated. The propagator for the gauge field is calculated and the interaction between the plate and a point-like electric charge is computed. The boundary condition imposed on the vector field is taken to be the one that makes, on the plate, the normal component of the dual field strength to the plate vanish. It is shown that the image method is not valid in Lee-Wick electrodynamics. (orig.)

    An improved modified approach to compute the inverse discrete cosine transform (IDCT) is proposed based on B. G. Lee algorithm. We replace the multiplication operator in original B. G. Lee algorithm with addition and shift operators and looking-up table to implement the fix-point computation. Due to the absence of the multiplication operator, this modified algorithm will take less time to complete the same computation.

  20. Predicting bed form roughness: the influence of lee side angle

    Science.gov (United States)

    Lefebvre, Alice; Winter, Christian

    2016-04-01

    Flow transverse bedforms (ripples and dunes) are ubiquitous in rivers and coastal seas. Local hydrodynamics and transport conditions depend on the size and geometry of these bedforms, as they constitute roughness elements at the bed. Bedform influence on flow energy must be considered for the understanding of flow dynamics, and in the development and application of numerical models. Common estimations or predictors of form roughness (friction factors) are based mostly on data of steep bedforms (with angle-of-repose lee slopes), and described by highly simplified bedform dimensions (heights and lengths). However, natural bedforms often are not steep, and differ in form and hydraulic effect relative to idealised bedforms. Based on systematic numerical model experiments, this study shows how the hydraulic effect of bedforms depends on the flow structure behind bedforms, which is determined by the bedform lee side angle, aspect ratio and relative height. Simulations reveal that flow separation behind bedform crests and, thus, a hydraulic effect is induced at lee side angles steeper than 11 to 18° depending on relative height, and that a fully developed flow separation zone exists only over bedforms with a lee side angle steeper than 24°. Furthermore, the hydraulic effect of bedforms with varying lee side angle is evaluated and a reduction function to common friction factors is proposed. A function is also developed for the Nikuradse roughness (k s), and a new equation is proposed which directly relates k s to bedform relative height, aspect ratio and lee side angle.

    Sake lees are solid parts filtered from the mash of sake, the traditional rice wine of Japan, which is brewed with Aspergillus oryzae and Saccharomyces cerevisiae. The moisture-holding activity of sake lees has long been recognized in Japan. However, the constituent responsible for this activity has not been elucidated. In this study, we first determined the structure of the glucosylceramides contained in sake lees. The glucosylceramides contained in sake lees were N-2'-hydroxyoctadecanoyl-l-O-β-D-glucopyranosyl-9-methyl-4,8-sphingadienine (d19:2/C18:0h), N-2'-hydroxyoctadecanoyl-l-O-β-D-glucopyranosyl-4,8-sphingadienine (d18:2/C18:0h), N-2'-hydroxyicosanoyl-l-O-β-D-glucopyranosyl-4,8-sphingadienine (d18:2/C20:0h) and N-2'-hydroxyicosanoyl-l-O-β-D-glucopyranosyl-4,8-sphingadienine (d18:2/C22:0h), which corresponded to those of A. oryzae and rice. The glucosylceramide produced by A. oryzae constituted the most abundant species (43% of the total glucosylceramide) in the sake lees. These results will be of value in the utilization of sake lees for cosmetics and functional foods.

    1994-01-01

    The Harvard ER-2 OH instrument is scheduled to be integrated into the NASA ER-2 high altitude aircraft ozone payload in August 1992. Design and fabrication is presently underway. This experiment is a descendant of a balloon borne instrument designed and built in the mid-1980s. The ER-2 instrument is being designed to measure OH and HO2 as part of the NASA ozone payload for the investigation of processes controlling the concentration of stratospheric ozone. Although not specifically designed to do so, it is hoped that valid measurements of OH and HO2 can be made in the remote free troposphere with this instrument.

    The Harvard Observing Project (HOP) is designed to get students excited about observational astronomy while collecting data valuable to the scientific community. The primary goal is to give undergraduates a chance to try out observing with “no strings attached”. Observations are led by experienced observers, mostly graduate students. This not only gives graduate students extra opportunities to interact and teach undergraduates, but also a chance for them to get more observing experience. Each semester, we choose an interesting target and monitor it each week over the course of the semester using Harvard University’s 16-inch DFM Clay Telescope. These observing projects often produce large amounts of data. This provides an excellent dataset for a young undergraduate to analyze. Some successful semester-long observing projects have included variable stars, supernova and binary systems. Short-term projects have included exoplanet candidate followup, asteroid and comet followup and collaborating with the Pro-Am White Dwarf Monitoring (PAWM) project in attempts to detect a transiting Earth-sized planet orbiting a white dwarf. Each dataset is an opportunity for an undergraduate to be introduced to scientific research and present the results to the community.

    Between 2009 and 2013, the Kepler spacecraft observed ~200,000 stars, repeatedly measuring their brightness to look for regular dimmings that could indicate the presence of a transiting planet (Borucki et al. 2010). This endeavor led to the discovery of thousands of planets. However, the data pertaining to one star, KIC 8462852, nicknamed “Tabby's Star” or “Boyajian's Star" indicated sporadic dimmings thought to be resulting from massive, evolving, and erratic shapes passing in front of the star (Boyajian et al. 2016, Wright and Sigurdsson 2016). Additional observations have indicated that KIC 8462852 has faded by approximately 20% over the past century (Wright and Sigurdsson 2016). Kepler is now observing other areas of space, and consequently, ground-based efforts have emerged in order to continue tracking the brightness of KIC 8462852. The Harvard Observing Project (HOP) is an observational astronomy initiative that engages undergraduate students and provides graduate students with the opportunity to lead sessions of data collection. During the fall 2016 semester, HOP will be observing KIC 8462852 in BVRI filters using Harvard's 16-inch DFM Clay telescope. We will present a light curve of the star spanning the course of three months.

  14. The 1951 Harvard student uprising against the intern match.

    Nakayama, Don K; Hendren, W Hardy

    2017-06-01

    In the fall of 1951, a group of Harvard medical students led by W. Hardy Hendren, III organized a national movement against the newly instituted match that would assign graduating seniors to hospital internship programs. Before then, hospitals with intern positions to fill rushed to secure commitments from students, who in turn accepted the first decent offer that came their way. Knowing that students could not risk waiting for a better offer, hospitals pushed them into making early commitments. When some students began getting offers in their junior and sophomore years, medical schools, professional groups, and hospitals organized the National Inter-association Committee on Internships to deal with the issue. The intern match was thus organized and scheduled to take place in 1952. When the plan was announced in mid-October 1951, Hendren recognized that the proposed algorithm placed students at a disadvantage if they did not get their first choice of hospitals. Facing resistance at every step from the National Inter-association Committee on Internships and putting his standing at Harvard Medical School at risk, Hendren led a nationwide movement of medical students to change the procedure to one that favored students' choices. Their success <1 month later established in the inaugural match the fundamental ethic of today's National Resident Matching Program to favor students' preferences at every step of the process.

    2011-01-01

    We study the constraints on the Lee-Wick Higgs sector arising from direct collider searches. We work in an effective-field theory framework, where all of the Lee-Wick partners are integrated out, with the sole exception of the Lee-Wick Higgs bosons. The resulting theory is a two-Higgs doublet model where the second doublet has wrong-sign kinetic and mass terms. We include the bounds coming from direct Higgs searches at both LEP and Tevatron using the code HiggsBounds, and show the currently excluded parameter space. We also analyze the prospects of LHC Run-I, finding that with a total integrated luminosity of 5 fb $^{-1}$ and a center-of-mass energy of 7 TeV, most of the parameter space for the SM-like CP-even Higgs will be probed.

    We write out the generic Dirac neutrino mass operator which possesses the Friedberg-Lee symmetry and find that its corresponding neutrino mass matrix is asymmetric. Following a simple way to break the Friedberg-Lee symmetry, we calculate the neutrino mass eigenvalues and show that the resultant neutrino mixing pattern is nearly tri-bimaximal. Imposing the Hermitian condition on the neutrino mass matrix, we also show that the simplified ansatz is consistent with current experimental data and favors the normal neutrino mass hierarchy.

  10. Morphology of the proboscis of Hubrechtella Juliae (Nemertea, Pilidiophora): implications for pilidiophoran monophyly.

    2013-12-01

    The proboscis of Hubrechtella juliae was examined using transmission electron microscopy, scanning electron microscopy, and confocal laser scanning microscopy to reveal more features of basal pilidiophoran nemerteans for morphological and phylogenetic analysis. The proboscis glandular epithelium consists of sensory cells and four types of gland cells (granular, bacillary, mucoid, and pseudocnidae-containing cells) that are not associated with any glandular systems; rod-shaped pseudocnidae are 15-25 μm in length; the central cilium of the sensory cells is enclosed by two rings of microvilli. The nervous plexus lies in the basal part of glandular epithelium and includes 26-33 (11-12 in juvenile) irregularly anastomosing nerve trunks. The proboscis musculature includes four layers: endothelial circular, inner diagonal, longitudinal, and outer diagonal; inner and outer diagonal muscles consist of noncrossing fibers; in juvenile specimen, the proboscis longitudinal musculature is divided into 7-8 bands. The endothelium consists of apically situated support cells with rudimentary cilia and subapical myocytes. Unique features of Hubrechtella's proboscis include: acentric filaments of the pseudocnidae; absence of tonofilament-containing support cells; two rings of microvilli around the central cilium of sensory cells; the occurrence of subendothelial diagonal muscles and the lack of an outer diagonal musculature (both states were known only in Baseodiscus species). The significance of these characters for nemertean taxonomy and phylogeny is discussed. The proboscis musculature in H. juliae and most heteronemerteans is bilaterally arranged, which can be considered a possible synapomorphy of Hubrechtellidae + Heteronemertea (= Pilidiophora).

    We study the matter-antimatter asymmetry through the leptogenesis mechanism in a specific model with the Friedberg-Lee (FL) symmetry. We relate the leptogenesis with the CP violating Dirac and Majorana phases in the Maki-Nakagawa-Sakata leptonic mixing matrix and illustrate the net baryon asymmetry of the universe in terms of these phases.

    Lee de Forest, Yale doctorate and Oscar winner, gave voice to the radio and the motion picture. Yet by the 1930s, after the radio and the Talkies were regular features of American life, Lee de Forest had seemingly lost everything. Why? Why didn’t he receive the recognition and acclaim he sought his entire life until years later in 1959, when he was awarded an Oscar? A lifelong innovator, Lee de Forest invented the three-element vacuum tube which he developed between 1906 and 1916 as a detector, amplifier, and oscillator of radio waves. As early as 1907, he was broadcasting music programming. In 1918, he began to develop a system for recording and playing back sound by using light patterns on motion picture film. In order to promote and demonstrate his process he made hundreds of short sound films, found theatres for their showing, and issued publicity to gain audiences for his invention. While he received many patents for this technology, he was ignored by the film industry. Lee de Forest, King of Radio, Te...

    2015-08-01

    In 1929 the newly-reorganized Rockefeller Foundation funded the work of a cross-disciplinary group at Harvard University called the Committee on Industrial Physiology (CIP). The committee's research and pedagogical work was oriented towards different things for different members of the alliance. The CIP program included a research component in the Harvard Fatigue Laboratory and Elton May's interpretation of the Hawthorne Studies; a pedagogical aspect as part of Wallace Donham's curriculum for Harvard Business School; and Lawrence Henderson's work with the Harvard Pareto Circle, his course Sociology 23, and the Harvard Society of Fellows. The key actors within the CIP alliance shared a concern with training men for elite careers in government service, business leadership, and academic prominence. But the first communications between the CIP and the Rockefeller Foundation did not emphasize training in human biology. Instead, the CIP presented itself as a coordinating body that would be able to organize all the varied work going on at Harvard that did not fit easily into one department, and it was on this basis that the CIP became legible to the President of Harvard, A. Lawrence Lowell, and to Rockefeller's Division of Social Sciences. The members of the CIP alliance used the term human biology for this project of research, training and institutional coordination.

    2014-01-01

    James Ewing Mears (1838-1919) was a founding member of the Philadelphia Academy of Surgery. His 1910 book, The Problem of Race Betterment, laid the groundwork for later authors to explore the uses of surgical sterilization as a eugenic measure. Mears left $60,000 in his will to Harvard University to support the teaching of eugenics. Although numerous eugenic activists were on the Harvard faculty, and two of its Presidents were also associated with the eugenics movement, Harvard refused the Mears gift. The bequest was eventually awarded to Jefferson Medical College in Philadelphia. This article explains why Harvard turned its back on a donation that would have supported instruction in a popular subject. Harvard's decision illustrates the range of opinion that existed on the efficacy of eugenic sterilization at the time. The Mears case also highlights a powerful irony: the same week Harvard turned down the Mears legacy, the U.S. Supreme Court endorsed eugenic sterilization in the landmark case of Buck v. Bell. Justice Oliver Wendell Holmes, Jr., graduate of Harvard and former member of its law faculty wrote the opinion in that case, including the famous conclusion: "Three generations of imbeciles are enough."

    Tropical veterinary parasites have been maintained by the Museum of Comparative Zoology (MCZ) at Harvard University since the mid 1800s. Most of these are maintained by the Department of Invertebrate Zoology, but many vectors and intermediate hosts are maintained by the Departments of Entomology and Malacology. The largest collections are of avian and mammalian ticks (Acarina) that are important as both parasites and vectors. Nematodes are second in numbers, followed by cestodes, trematodes, and several minor helminth groups, crustacean parasites of fish, and protozoan parasites of various hosts. The MCZ directed or participated in several major expeditions to tropical areas around the globe in the early 1900s. Many of these expeditions focused on human parasites, but hundreds of veterinary and zoonotic parasites were also collected from these and numerous, smaller, tropical expeditions. Host sources include companion animals, livestock, laboratory species, domestic fowl, reptiles, amphibians, exotics/zoo animals, commercially important fishes, and other wildlife. Specimens are curated, either fixed whole in vials or mounted on slides as whole mounts or histopathological sections. The primary emphasis of MCZ's current work with tropical veterinary parasites is on voucher specimens from epidemiological, experimental, and clinical research.

  13. A new formulation of Lee-Wick quantum field theory

    Science.gov (United States)

    Anselmi, Damiano; Piva, Marco

    2017-06-01

    The Lee-Wick models are higher-derivative theories that are claimed to be unitary thanks to a peculiar cancelation mechanism. In this paper, we provide a new formulation of the models, to clarify several aspects that have remained quite mysterious, so far. Specifically, we define them as nonanalytically Wick rotated Euclidean theories. The complex energy plane is divided into disconnected regions, which can be related to one another by a well-defined, albeit nonanalytic procedure. Working in a generic Lorentz frame, the models are intrinsically equipped with the right recipe to treat the pinchings of the Lee-Wick poles, with no need of external ad hoc prescriptions. We describe these features in detail by calculating the one-loop bubble diagram and explaining how the key properties generalize to more complicated diagrams. The physical results of our formulation are different from those of the previous ones. The unusual behaviors of the physical amplitudes lead to interesting phenomenological predictions.

  15. A Higher-Derivative Lee-Wick Standard Model

    CERN Document Server

    Carone, Christopher D

    2009-01-01

    The Lee-Wick Standard Model assumes a minimal set of higher-derivative quadratic terms that produce a negative-norm partner for each Standard Model particle. Here we introduce additional terms of one higher order in the derivative expansion that give each Standard Model particle two Lee-Wick partners: one with negative and one with positive norm. These states collectively cancel unwanted quadratic divergences and resolve the hierarchy problem as in the minimal theory. We show how this next-to-minimal higher-derivative theory may be reformulated via an auxiliary field approach and written as a Lagrangian with interactions of dimension four or less. This mapping provides a convenient framework for studies of the formal and phenomenological properties of the theory.

    Full Text Available We discuss some aspects concerning the electromagnetic sector of the abelian Lee-Wick (LW quantum electrodynamics (QED. Using the Dirac’s theory of constrained systems, the higher-order canonical quantization of the LW electromagnetism is performed. A quantum bound on the LW heavy mass is also estimated using the best known measurement of the anomalous magnetic moment of the electron. Finally, it is shown that magnetic monopoles can coexist peacefully in the LW scenario.

    2016-06-01

    Full Text Available Jung Young Lee is a Korean-born theologian who employs creatively the doctrine of the Trinity from an Asian worldview. This article aims to analyze Lee’s approaches of the Trinity with the Yin-Yang symbolism. The main reference is based on the book written by him entitled ‘The Trinity in Asian Perspective (1996’. Lee has turned his attention to the topic of Trinity through the lens of the culture and thought patterns of his own milieu. One of the leading point in presenting Yin-Yang principle as Trinitarian thinking, Lee examines the interpretation of the term “in” in the Bible, "Believe me that I am in the Father and the Father is in me" (John 14:11. The statement leads to the point that Yin and Yang cannot exist without each other because relationality is given priority than individuality. The idea is based on the terminology of ‘both/and’. So, ‘and’ indicates a Trinitarian statement, there is interdependence and unification. With reference to Trinity, the Father and the Son are One because of ‘and’. In addition, the same concept implements to the Holy Spirit. Lee views ‘and’ is not only a linking principle in both-and thinking but also the principle that is ‘between’ two. When ‘two’ exists, the third also exist between them. Based on the idea of ‘middle’, represents the connecting element between two, which contributes for the existence of the Third. Accordingly, the Spirit is the third element in the Trinity relationship.

    The Friedberg-Lee model is studied at finite temperature and density. By using the finite temperature field theory, the effective potential of the Friedberg-Lee model and the bag constant B(T) and B(T,μ) have been calculated at different temperatures and densities. It is shown that there is a critical temperature TC≃106.6 MeV when μ=0 MeV and a critical chemical potential μ≃223.1 MeV for fixing the temperature at T=50 MeV. We also calculate the soliton solutions of the Friedberg-Lee model at finite temperature and density. It turns out that when T⩽TC (or μ⩽μC), there is a bag constant B(T) [or B(T,μ)] and the soliton solutions are stable. However, when T>TC (or μ>μC) the bag constant B(T)=0 MeV [or B(T,μ)=0 MeV] and there is no soliton solution anymore, therefore, the confinement of quarks disappears quickly.

By using the finite temperature field theory, the effective potential of the Friedberg-Lee model and the bag constant $B(T)$ and $B(T,\\mu)$ have been calculated at different temperatures and densities. It is shown that there is a critical temperature $T_{C}\\simeq 106.6 \\mathrm{MeV}$ when $\\mu=0 \\mathrm{MeV}$ and a critical chemical potential $\\mu \\simeq 223.1 \\mathrm{MeV}$ for fixing the temperature at $T=50 \\mathrm{MeV}$. We also calculate the soliton solutions of the Friedberg-Lee model at finite temperature and density. It turns out that when $T\\leq T_{C}$ (or $\\mu \\leq \\mu_C$), there is a bag constant $B(T)$ (or $B(T,\\mu)$) and the soliton solutions are stable. However, when $T>T_{C}$ (or $\\mu>\\mu_C$) the bag constant $B(T)=0 \\mathrm{MeV}$ (or $B(T,\\mu)=0 \\mathrm{MeV}$) and there is no soliton solution anymore, therefore, the confinement of quarks disappears quickly.

    B. van der Westhuizen

    2007-07-01

    Full Text Available The purpose of this article is firstly to distinguish between the notions “external locus of control” and “internal locus of control”, secondly to indicate ways in which the locus of control in humour in “The Gruffalo” by Julia Donaldson and Axel Scheffler can be identified and thirdly to indicate possible ways in which emphasis on the internal locus of control in the young reader can assist him/her in the development of a general mental/- psychological well-being. Different kinds of literary humour contribute to the ways in which young listeners/readers can identify with stories, poems, dramas and films. The young listener/reader can recognise him/herself in humorous situations, in the humorous use of imagery, wordplay and illustrations/visuals. He/she can also identify with or distance him-/herself from or reject the characters, the values represented and the author who created the text. When in interaction with the works of authors who use negative as well as positive kinds of humour to point out the dos and don’ts, the rights and the wrongs in life, the horizon of a young listener’s/reader’s experience can be expanded. Such a reading would contribute to the development of the young reader’s cognitive, emotional, social and moral values as it links up with an unconscious or conscious decision about the locus of control in his/her life.

    The primary care clerkship (PCC) at Harvard Medical School was established in 1997. The goals are to provide students with longitudinal experiences with patients and to include modern themes in the curriculum: managing illness and clinical relationships over time; finding the best available answers to clinical questions; preventing illness and promoting health; dealing with clinical uncertainty; getting the best outcomes with available resources; working in a health care team; and sharing decision making with patients. The PCC, a required course in the clinical years, meets one afternoon a week for nine months. Students spend three afternoons per month in primary care practices, where they see three to five patients per session and follow at least one patient ("longitudinal patient") over time. Classroom sessions, in both large- and small-group formats, promote a common educational philosophy and experience, and reinforce habits of problem-based learning established in the preclinical years. The students rated 74% of their preceptors excellent, especially praising their ability to facilitate and support good interpersonal relationships with patients, their ability to encourage students' independent evaluation of patients (as opposed to shadowing), and their enthusiasm for teaching. Students saw their longitudinal patients a mean of 4.8 times; 83% saw their patients at least three times. The PCC complements the curriculum of block clerkships in hospitals, and because the two are offered concurrently, students are required to come to terms with two substantially different cultures within medicine. Other medical schools are beginning to develop longitudinal clerkships to ensure that students have essential educational experiences that are difficult to achieve in block, hospital-based clerkships.

    We investigate the Friedberg-Lee (FL) symmetry and its promotion to include the {mu}-{tau} symmetry, and call this the twisted FL symmetry. Based on the twisted FL symmetry, two possible schemes are presented toward the realistic neutrino mass spectrum and the tri-bimaximal mixing. In the first scheme, we suggest the semi-uniform translation of the FL symmetry. The second one is based on the S{sub 3} permutation family symmetry. The breaking terms, which are twisted FL symmetric, are introduced. Some viable models in each scheme are also presented. (orig.)

    We write out the generic Dirac neutrino mass operator which possesses the Friedberg-Lee (FL) symmetry and find that its corresponding neutrino mass matrix is asymmetric. Following a simple way to break the FL symmetry, we calculate the neutrino mass eigenvalues and show that the resultant neutrino mixing pattern is nearly tri-bimaximal. Imposing the Hermitian condition on the neutrino mass matrix, we also show that the simplified ansatz is consistent with current experimental data and favors the normal neutrino mass hierarchy.

    (Abstract only) We describe the volunteer-driven project to digitize published visual observations found in the Annals of the Harvard College Observatory, the publication of record for Harvard's variable star data archives prior to the founding of the AAVSO. The addition of published data from the 19th and early 20th centuries to the AAVSO International Database has the potential to enable significant new science by extending long term light curves farther back in time with high-quality visual and photographic data. AAVSO volunteers working on this project have together digitized over well over 10,000 observations from the Harvard Annals, adding decades to the light curves of some stars. We highlight the work done so far, and show the potential to expand the project by both AAVSO Headquarters and by the volunteers themselves.

    2015-06-01

    In this article, we develop a fully integrated and dynamic Bayesian approach to forecast populations by age and sex. The approach embeds the Lee-Carter type models for forecasting the age patterns, with associated measures of uncertainty, of fertility, mortality, immigration, and emigration within a cohort projection model. The methodology may be adapted to handle different data types and sources of information. To illustrate, we analyze time series data for the United Kingdom and forecast the components of population change to the year 2024. We also compare the results obtained from different forecast models for age-specific fertility, mortality, and migration. In doing so, we demonstrate the flexibility and advantages of adopting the Bayesian approach for population forecasting and highlight areas where this work could be extended.

  2. Perturbative unitarity of Lee-Wick quantum field theory

    Science.gov (United States)

    Anselmi, Damiano; Piva, Marco

    2017-08-01

    We study the perturbative unitarity of the Lee-Wick models, formulated as nonanalytically Wick rotated Euclidean theories. The complex energy plane is divided into disconnected regions and the values of a loop integral in the various regions are related to one another by a nonanalytic procedure. We show that the one-loop diagrams satisfy the expected, unitary cutting equations in each region: only the physical d.o.f. propagate through the cuts. The goal can be achieved by working in suitable subsets of each region and proving that the cutting equations can be analytically continued as a whole. We make explicit calculations in the cases of the bubble and triangle diagrams and address the generality of our approach. We also show that the same higher-derivative models violate unitarity if they are formulated directly in Minkowski spacetime.

    The Friedberg-Lee (FL) symmetry is generated by a transformation of a fermionic field q to q+xiz. This symmetry puts very restrictive constraints on allowed terms in a Lagrangian. Applying this symmetry to N fermionic fields, we find that the number of independent fields is reduced to N-1 if the fields have gauge interaction or the transformation is a local one. Using this property, we find that a seesaw model originally with three generations of left- and right-handed neutrinos, with the left-handed neutrinos unaffected but the right-handed neutrinos transformed under the local FL translation, is reduced to an effective theory of minimal seesaw which has only two right-handed neutrinos. The symmetry predicts that one of the light neutrino masses must be zero.

  4. Modified Friedberg-Lee symmetry for neutrino mixing

    Zhao, Zhen-hua

    2015-12-01

    In this paper, we put forward a special neutrino mass matrix which is invariant under a modified Friedberg-Lee (FL) transformation νe→νe-2 ξ and νμ ,τ→νμ ,τ+ξ with ξ being a space-time independent element of the Grassmann algebra. Compared to the original FL symmetry (with the transformation νe ,μ ,τ→νe ,μ ,τ+ξ ) which results in the TM2 neutrino mixing, the modified FL symmetry will lead us to the TM1 mixing which has a better agreement with the experimental results. While the original FL symmetry has to be broken in order to produce a realistic neutrino mass spectrum, the modified FL symmetry is allowed to remain intact and give us a vanishing m1. A combination of the FL symmetry with the μ -τ reflection symmetry is also discussed.

    The excitation spectrum of a nucleon with spin 1/2 is examined using the Friedberg-Lee model containing constituent quarks and a scalar meson. An appropriate method of quantization for the non-linear meson field is employed by taking account of the non-topological soliton existing at the classical level. Our model space for the nucleon resonances includes the three quark plus one meson state, in addition to the pure three quark state. The excitation spectrum in this model space reveals that the positive parity state appears as the first excited state associated with the 0s-excitation of the scalar meson. The meson excitation also generates an additional negative parity state apart from the well-known 0p-excitation of the quark.

    Friedberg, Lee and Zhao (FLZ) proposed a method for effectively evaluating the eigenenergies and eigen wavefunctions of quantum systems. In this work, we study several special cases to investigate applicability of the method.Concretely, we calculate the ground-state eigenenergy of the Hellmann potential as well as the Cornell potential, and also evaluate the energies of the systems where linear term is added to the Coulomb as a perturbation. The results obtained in this method have a surprising agreement with the traditional method or the numerical results. Since the results in this method have obvious analyticity compared to that in other methods, and because of the simplicity for calculations this method can be applied to solving the Schrodinger equation and provides us a better understanding of the physical essence of the concerned systems. But meanwhile applications of the FLZ method are restricted at present, especially for certain potential forms, but due to its obvious advantages, it should be further developed.

Applying this symmetry to $N$ fermionic fields, we find that the number of independent fields is reduced to $N-1$ if the fields have gauge interaction or the transformation is a local one.

    The Yuan-Tseh Lee Array for Microwave Background Anisotropy (AMiBA) is the first interferometer dedicated to studying the cosmic microwave background (CMB) radiation at 3mm wavelength. The choice of 3mm is to minimize the contributions from foreground synchrotron radiation and Galactic dust emission. The initial configuration of seven 0.6m telescopes mounted on a 6-m hexapod platform, was dedicated in October 2006 on Mauna Loa, Hawaii. Scientific operations began with the detection of a number of clusters of galaxies via the thermal Sunyaev-Zel'dovich effect. We compare our data with Subaru weak lensing data in order to study the structure of dark matter. We also compare our data with X-ray data in order to derive the Hubble constant.

  13. Perturbations in Symmetric Lee-Wick Bouncing Universe

    CERN Document Server

    Cho, Inyong

    2012-01-01

    We investigate the tensor and the scalar perturbations in the symmetric bouncing universe driven by one ordinary field and its Lee-Wick partner field which is a ghost. We obtain the even- and the odd-mode functions of the tensor perturbation in the matter-dominated regime. The tensor perturbation grows in time during the contracting phase of the Universe, and decays during the expanding phase. The power spectrum for the tensor perturbation is evaluated and the spectral index is given by $n_{\\rm T} =6$. We add the analysis on the scalar perturbation by inspecting the even- and the odd-mode functions in the matter-dominated regime, which was studied numerically in our previous work. We conclude that the comoving curvature by the scalar perturbation is constant in the super-horizon scale and starts to decay in the far sub-horizon scale while the Universe expands.

  15. Super-renormalizable or finite Lee-Wick quantum gravity

    Science.gov (United States)

    Modesto, Leonardo

    2016-08-01

    We propose a class of multidimensional higher derivative theories of gravity without extra real degrees of freedom besides the graviton field. The propagator shows up the usual real graviton pole in k2 = 0 and extra complex conjugates poles that do not contribute to the absorptive part of the physical scattering amplitudes. Indeed, they may consistently be excluded from the asymptotic observable states of the theory making use of the Lee-Wick and Cutkosky, Landshoff, Olive and Polkinghorne prescription for the construction of a unitary S-matrix. Therefore, the spectrum consists of the graviton and short lived elementary unstable particles that we named ;anti-gravitons; because of their repulsive contribution to the gravitational potential at short distance. However, another interpretation of the complex conjugate pairs is proposed based on the Calmet's suggestion, i.e. they could be understood as black hole precursors long established in the classical theory. Since the theory is CPT invariant, the conjugate complex of the micro black hole precursor can be interpreted as a white hole precursor consistently with the 't Hooft complementarity principle. It is proved that the quantum theory is super-renormalizable in even dimension, i.e. only a finite number of divergent diagrams survive, and finite in odd dimension. Furthermore, turning on a local potential of the Riemann tensor we can make the theory finite in any dimension. The singularity-free Newtonian gravitational potential is explicitly computed for a range of higher derivative theories. Finally, we propose a new super-renormalizable or finite Lee-Wick standard model of particle physics.

  15. Women peers in the scientific realm: Sarah Bowdich (Lee)'s expert collaborations with Georges Cuvier, 1825–33

    Science.gov (United States)

    2015-01-01

    The accepted rule for women contributing to nineteenth-century science before 1851 was that they could play only secondary roles in its production and authorship—as translators, illustrators, popularizers—and these by virtue of kinship or marriage to eminent scientists in the field or the laboratory. Sarah Bowdich (Lee) (1791–1856) presents an important amendment to this rule. As an explorer of West Africa on an equal scientific footing with her husband, and then a writer of science independently after his early death, she had other key roles as Georges Cuvier's cross-Channel scientific collaborator and as his first biographer. This article investigates and reframes Sarah's many individual achievements in science and its writing, to examine the larger questions of her case. How were her publications and ‘uneasy career’ in science possible? Can research on women in science today find inspiration in her example? PMID:26489182

Her role was not only based on the fact she was a midwife, but she also managed to be a wife and an emperor’s mother. Honoured with several adjectives such as Augusta, Pía, Felix or mater Augustorum and mater castrorum, her influence spread all over the Empire. Therefore, we are dealing with a figure that went out from the margins imposed to women by the Roman society.

  17. Effacement énonciatif et doxa dans le discours théorique : l’exemple de Julia Kristeva The erasement of subjectivity and doxa in theoretical discourse: the case of Julia Kristeva

    Full Text Available Cet article entend contribuer à la réflexion menée sur les phénomènes d’effacement énonciatif, en particulier dans le discours théorique. L’approche se veut inséparablement rhétorique et socio-historique et porte sur un corpus composé des principaux articles publiés par Julia Kristeva dans les années 1960. Ceux-ci sont contrastés avec des interventions ultérieures de la théoricienne, répondant à d’autres enjeux et stratégies. Les effets construits par l’effacement énonciatif sont envisagés comme des opérations sur la doxa, orientées par un contrat rhétorique. Cette notion, située à l’intersection du socio-historique et du discursif, se veut un outil complémentaire pour l’analyse de l’efficace des discours dans un état de société.This paper tackles the issue of enunciative effacement, particularly in theoretical discourse. The approach is both rhetorical and socio-historical, as it focuses on texts published by Julia Kristeva in the sixties and contrasts them with more recent Kristeva speeches, corresponding to other issues and strategies. The effects brought about by enunciative effacement are considered as operations on doxa, which are oriented by a rhetorical contract. This notion, both socio-historical and rhetorical, provides a tool for analyzing the efficiency of discourses in a given state of society.

  18. Seeking Byzantium on the Borders of Narration, Identity, Space and Time in Julia Kristeva's Novel Murder in Byzantium

    Directory of Open Access Journals (Sweden)

    Helena Bodin

    2009-03-01

    Full Text Available This article discusses the notion of Byzantium and Byzantium's potential capacities as a multifaceted borderland, as shaped and perceived in Julia Kristeva's novel Murder in Byzantium. In spite of its title, this is not a historical, but rather a so-called total novel, which reconciles several different plots - romantic, criminal, political and philosophical. It relies on both fictive and historical texts, especially on The Alexiad, written in the 12th century by the Byzantine princess and the first female historian ever, Anna Comnena. Through a literary analysis, this article shows how Byzantium is shaped in the novel by transgressions of the borders of narration, identity, space and time. Byzantium is thus of great interest to the general public and an academic discussion of borders, origin, history and culture, so important for the discussion of Europe's role today in - or, as suggested in the novel, perhaps between - Eastern and Western cultures.

  19. James Lee Byars 1/2 an autobiography, sourcebook

    "I see my autobiography as an arbitrary segment of so many pages of time, of things that I have paid attention to at this point in my life," wrote James Lee Byars (1932-1997) in 1969. He was then 37, about half the average male lifespan at the time, and accordingly thought it appropriate to write his "1/2 autobiography." Byars' art ranged from highly refined objects to extremely minimal performance and events, and books, ephemera and correspondence that he distributed widely among friends and colleagues. Today, more than 15 years after his death, assessments of his art must negotiate Byars' performance of his charismatic self in his life and art. For his first major posthumous survey in the US, exhibition curators Magalí Arriola and Peter Eleey decided to produce a catalogue in two "halves," playing on his "1/2 autobiography": a catalogue of the exhibition itself, including new scholarship, and a sourcebook of primary documents. 1/2 an Autobiography, Sourcebook constitutes the latter volume--a reference guid...

  20. Tri-Bimaximal Mixing from Twisted Friedberg-Lee Symmetry

    CERN Document Server

    Araki, Takeshi

    2008-01-01

    We consider the tri-bimaximal generation mixing in terms of the Friedberg-Lee (FL) symmetry. The symmetry is a kind of translational one for the fermion field operators. The symmetry with uniform translation for each generation of neutrinos can partially realize the desired form of the neutrino mass matrix for the tri-bimaximal mixing but should be improved to obtain the experimentally favored neutrino mass spectrum. It is firstly pointed out that patterns of the uniformity breaking are important for resulting form of the neutrino mass matrix. Then we propose a promotion of the FL symmetry to have the $\\mu - \\tau$ one, and call that the twisted FL symmetry. Based on the twisted FL symmetry, two possible schemes are also presented toward the realistic neutrino mass spectrum and the tri-bimaximal mixing. The first possible scheme is that the uniformity of the FL symmetry is broken by terms preserving the twisted FL one. The second one is based on the $S_3$ permutation family symmetry. The breaking terms, which ...

    Light sterile neutrinos of mass about an eV with mixing U{sup -tilde}{sub ls} of a few percent to active neutrinos may solve some anomalies shown in experimental data related to neutrino oscillation. How to have light sterile neutrinos is one of the theoretical problems which have attracted a lot of attentions. In this article we show that such an eV scale light sterile neutrino candidate can be obtained in a seesaw model in which the right-handed neutrinos satisfy a softly-broken Friedberg–Lee (FL) symmetry. In this model a right-handed neutrino is guaranteed by the FL symmetry to be light comparing with other two heavy right-handed neutrinos. It can be of eV scale when the FL symmetry is softly broken and can play the role of eV scale sterile neutrino needed for explaining the anomalies of experimental data. This model predicts that one of the active neutrino is massless. We find that this model prefers inverted hierarchy mass pattern of active neutrinos than normal hierarchy. An interesting consequence of this model is that realizing relatively large |U{sup -tilde}{sub es}| and relatively small |U{sup -tilde}{sub μs}| in this model naturally leads to a relatively small |U{sup -tilde}{sub τs}|. This interesting prediction can be tested in future atmospheric or solar neutrino experiments.

    The problem on finite amplitude internal waves arising in a steady non-homogeneous flow over an uneven bottom is considered. Semi-analytical model deals with asymptotic solutions of the Euler equations of uniformly stratified fluid. Approximate solutions are constructed by the perturbation procedure combined with the Fourier method of modal expansion. Preliminary simulations used either of the first-order linear solution and the second-order non-linear solution (see [1,2]), and these numerical calculations found the fragmentation effect which occurs for near-field wave patterns forced by multi-bumped topography of finite extension. In this paper, we explain analytically the existence of sharp fronts which separate the flow domains having different wave scales. The results are illustrated numerically via modeling of wave structures generated by real bottom topography. References [1] N. Makarenko, J.

  5. Lee-Yang Model in Presence of Defects

    Deeb, Omar El

    2015-01-01

    I choose the Lee-Yang model and go through different approaches to analyze it using the form factor approach and the bootstrap program, the lattice description and the lattice TBA equations for a full understanding of the model. The bootstrap program aims to explicitly solve 1+1 dimensional integrable quantum field theories. In the first step, called the S-matrix bootstrap, the scattering matrix, is determined from its properties. In developing a defect form factor program the first step is the T-matrix bootstrap. Interacting integrable defect theories are purely transmitting and topological. We analyze both operators localized in the bulk and also on the defect. By finding their solutions, the spectral representation of any correlator can be determined. Next we consider the model on the lattice. The lattice approach allows to obtain both massive and massless excited TBA equations by studying the continuum scaling limit of the associated integrable lattice models. The most important input from the lattice app...

  6. Effect of the Lee-Wick partners in the evolution of the early universe

    Bhattacharya, Kaushik

    2012-01-01

    Recently some work has been done on Lee-Wick standard model where the authors tried to tackle the hierarchy problem by using higher derivative field theory. All those theories require unusual Lee-Wick partners to the Standard model particles where these unusual fields appear with negative signs in the Lagrangian. The thermodynamics of such unusual Lee-Wick particles has also been studied. In the present article the thermodynamic results of the Lee-Wick partner infested universe have been applied in a model where there is one Lee-Wick partner to each of the standard model particle. In this model one can analytically calculate the time-temperature relation in the very early radiation dominated universe which shows interesting new physics. The article also tries to point out how a Lee-Wick particle dominated early cosmology transforms into the standard cosmological model. Based on the results of the previous analysis a brief discussion on the more realistic model, which can accommodate two Lee-Wick parters for e...

  8. An analytical model for the amplitude of lee waves forming on the boundary layer inversion

    Lee waves are horizontally propagating gravity waves with a typical wavelength of 5-15 km that may be generated when stratified flow is lifted over a mountain. A frequently observed type of such waves is that of interfacial lee waves. Those develop, similar to surface waves on a free water surface, when the upstream flow features a density discontinuity. Such conditions are often present for example at the capping inversion in boundary layer flow. The dynamics of interfacial lee waves can be described concisely with linear interfacial gravity wave theory. However, while this theoretical framework accurately describes the wavelength, it fails to properly predict the amplitude of lee waves. It is well known that large amplitude lee waves may lead to low-level turbulence, which poses a potential hazard for aviation. Therefore, this property of interfacial lee waves deserves further attention. In this study, we develop a simple analytical model for the amplitude of lee waves forming on the boundary layer inversion. This model is based on the energetics of two-layer flow. We obtain an expression for the wave amplitude by equating the energy loss across an internal jump with the energy radiation through lee waves. The verification of the result with water tank experiments of density-stratified two-layer flow over two-dimensional topography from the HYDRALAB campaign shows good agreement between theory and observations. This new analytical model may be useful in determining potential hazards of interfacial lee waves with negligible computational cost as compared to numerical weather prediction models.

  9. About the triviality of the higher derivative sector in the abelian Lee-Wick model

    CERN Document Server

    Fiorentini, D

    2016-01-01

    Canonical quantization is reviewed here for the Abelian Lee-Wick model by using the Dirac constraints method. New degrees of freedom associated to the (higher derivatives) Lee-Wick ghost are excluded from the (physical) space of observables by a new prescription, based on the Nielsen-type BRST-extended symmetry for the Lee-Wick mass term. We prove that this prescription is nothing but an effective form of implementing the cohomological triviality of the higher-derivative pure sector associated to the existence of a new exclusive higher-derivative BRST symmetry.

  10. "They Sweat for Science": The Harvard Fatigue Laboratory and Self-Experimentation in American Exercise Physiology.

    Science.gov (United States)

    Johnson, Andi

    2015-08-01

    In many scientific fields, the practice of self-experimentation waned over the course of the twentieth century. For exercise physiologists working today, however, the practice of self-experimentation is alive and well. This paper considers the role of the Harvard Fatigue Laboratory and its scientific director, D. Bruce Dill, in legitimizing the practice of self-experimentation in exercise physiology. Descriptions of self-experimentation are drawn from papers published by members of the Harvard Fatigue Lab. Attention is paid to the ethical and practical justifications for self-experimentation in both the lab and the field. Born out of the practical, immediate demands of fatigue protocols, self-experimentation performed the long-term, epistemological function of uniting physiological data across time and space, enabling researchers to contribute to a general human biology program.

  11. The rise of pathophysiologic research in the United States: the role of two Harvard hospitals.

    Science.gov (United States)

    Tishler, Peter V

    2013-01-01

    Pathophysiologic research, the major approach to understanding and treating disease, was created in the 20th century, and two Harvard-affiliated hospitals, the Peter Bent Brigham Hospital and Boston City Hospital, played a key role in its development. After the Flexner Report of 1910, medical students were assigned clinical clerkships in teaching hospitals. Rockefeller-trained Francis Weld Peabody, who was committed to investigative, pathophysiologic research, was a critical leader in these efforts. At the Brigham, Harvard medical students observed patients closely and asked provocative questions about their diseases. Additionally, physicians returned from World War I with questions concerning the pathophysiology of wartime injuries. At the Boston City Hospital's new Thorndike Memorial Laboratory, Peabody fostered investigative question-based research by physicians. These physicians expanded pathophysiologic investigation from the 1920s. Post-war, Watson and Crick's formulation of the structure of DNA led shortly to modern molecular biology and new research approaches that are being furthered at the Boston Hospitals.

    Previous biomolecular and animal studies have shown that a room-temperature far-infrared-rayemitting ceramic material (bioceramic) demonstrates physical-biological effects, including the normalization of psychologically induced stress-conditioned elevated heart rate in animals. In this clinical study, the Harvard step test, the resting metabolic rate (RMR) assessment and the treadmill running test were conducted to evaluate possible physiological effects of the bioceramic material in human patients. The analysis of heart rate variability (HRV) during the Harvard step test indicated that the bioceramic material significantly increased the high-frequency (HF) power spectrum. In addition, the results of RMR analysis suggest that the bioceramic material reduced oxygen consumption (VO2). Our results demonstrate that the bioceramic material has the tendency to stimulate parasympathetic responses, which may reduce resting energy expenditure and improve cardiorespiratory recovery following exercise.

    2008-01-01

    Digital Access to a Sky Century @ Harvard (DASCH) is a project to digitize the collection of ~500,000 glass photographic plates held at Harvard College Observatory. The collection spans the time period from 1880 to 1985, during which time every point on the sky has been observed approximately 500 to 1000 times. In this paper we describe the results of the DASCH commissioning run, during which we developed the data-reduction pipeline and fine-tuned the digitzer's performance and operation. This initial run consisted of 500 plates taken from a variety of different plate-series, all containing the open cluster Praeseppe (M44). We report that accurate photometry at the 0.1mag level is possible on the majority of plates, and demonstrate century-long light-curves of various types of variable stars in and around M44.

  14. Harvard v. Canada: the myc mouse that still squeaks in the maze of biopatent law.

    Science.gov (United States)

    Deftos, L J

    2001-07-01

    The Canadian Supreme Court will soon make a decision about Harvard University's long-standing application for a Canadian patent on a mouse transgenic for the myc oncogene. That decision could reignite in North America the controversy that continues in Europe and elsewhere to surround the patenting of life forms. The tortuous steps in this 15-year patent maze are marked by the arguments about life patents that attended the U.S. Supreme Court's decision in Diamond v. Chakrabarty. This patent dispute about oil-digesting bacteria cracked open the door for animal patents in the United States and other countries, even though the legal arguments involved were based on patent applications for corn seeds and oysters, not mammals. The patent challenge to the Harvard mouse by the Canadian government now threatens to close this door in Canada. The arguments against life patents are commonly based on moral and religious grounds that regard the sanctity of life and oppose its commodification. The most compelling arguments for such patents are based on the benefits they deliver through commercial exploitation of inventions. The debate about patenting animals has been more heated outside North America and cacaphonic in the Third World. However, the Canadian debate could be amplified by the U.S. Supreme Court's recent entry on the biopatent stage through the side door of a new corn seed patent dispute. A narrow legal analysis by the Canadian Supreme Court would award the mouse patent to Harvard, while a policy analysis might support the government's challenge of the patent. Although the impact of the Harvard mouse patent process in Canada could be just a squeak, opponents of patenting life can mount the myc mouse to once again roar their opposition to animal patents. And the sound could resonate through the arguments about both biopatents and human cloning, with potentially important effects for academia, industry, and the public.

    Patients, providers, and policy leaders need a new moral compass to guide them in the turbulent U.S. health care system. Task forces have proposed excellent ethical codes, but these have been seen as too abstract to provide guidance at the front lines. Harvard Pilgrim Health Care's ten-year experience with an organizational ethics program suggests ways in which health care organizations can strengthen transparency, consumer focus, and overall ethical performance and contribute to the national health policy dialogue.

  7. Physical modelling of baroclinic development in the lee of the Alps

    Directory of Open Access Journals (Sweden)

    E. Ferrero

    1997-06-01

    Full Text Available When baroclinic development is triggered by an obstacle, like an extended mountain range, the so-called lee, or secondary cyclogenesis can develop. The presence of the obstacle exerts a blocking effect on the lower layers of the impinging airflow, forcing them to go round its borders and reach the lee region with a delay. Blocking and delay are both responsible for the initial pressure decrease downwind of the mountain and for the subsequent proper downstream baroclinic development. According to this rather simple scheme, a cyclogenesis episode in the lee of the Alps was simulated in a hydraulic turntable. The results of these experiments showed a good agreement, both from a qualitative and quantitative point of view, with the analysis of an episode of lee cyclogenesis coupled to a cold outbreak in the Mediterranean, which actually occured in Southern Europe downstream of the Alps.

    The present work is a systematic approach for valorization of wine lees regarding the recovery of squalene, a bioactive lipid. Such a study is presented for the first time in literature. Separate examination of squalene content in "light" and "heavy" lees from different vinification processes by RP-HPLC demonstrated that these waste streams can be used as a source for this lipid, despite variations due to technological or genetic effects. Next, ultrasound assisted extraction of squalene from the "industrial waste" (the mixture of wine lees generated from different wines) using n-hexane was optimized with the aid of response surface methodology (independent variables: sonication duration and duty cycles). Autolysis was monitored through optical microscopy. Squalene yield (0.6 ± 0.08 g SQ/kg dry lees) was comparable to that of recently examined potential sources (0.2-0.35 g SQ/kg dry olive pomace and 0.06 g SQ/kg olive leaves).

    Efficient conversion of beer lees wastes into biohydrogen gas by microorganisms was reported for the first time. Batch tests were carried out to analyze influences of several environmental factors on yield of H{sub 2} from beer lees wastes. The maximum yield of H{sub 2} 68.6mlH{sub 2}/g TVS was observed, the value is about 10-fold as compared with that of raw beer lees wastes. The hydrogen content in the biogas was more than 45% and there was no significant methane observed in this study. In addition, biodegradation characteristics of the substrate were also discussed. The results indicated that the HCl pretreatment of the substrate plays a key role in the conversion of the beer lees wastes into biohydrogen by the cow dung composts. (author)

    For the template-free modeling of human targets of CASP11, we utilized two of our modeling protocols, LEE and LEER. The LEE protocol took CASP11-released server models as the input and used some of them as templates for 3D (three-dimensional) modeling. The template selection procedure was based on the clustering of the server models aided by a community detection method of a server-model network. Restraining energy terms generated from the selected templates together with physical and statistical energy terms were used to build 3D models. Side-chains of the 3D models were rebuilt using target-specific consensus side-chain library along with the SCWRL4 rotamer library, which completed the LEE protocol. The first success factor of the LEE protocol was due to efficient server model screening. The average backbone accuracy of selected server models was similar to that of top 30% server models. The second factor was that a proper energy function along with our optimization method guided us, so that we successfully generated better quality models than the input template models. In 10 out of 24 cases, better backbone structures than the best of input template structures were generated. LEE models were further refined by performing restrained molecular dynamics simulations to generate LEER models. CASP11 results indicate that LEE models were better than the average template models in terms of both backbone structures and side-chain orientations. LEER models were of improved physical realism and stereo-chemistry compared to LEE models, and they were comparable to LEE models in the backbone accuracy.

    Full Text Available Infection by Escherichia coli and Shigella species are among the leading causes of death due to diarrheal disease in the world. Shiga toxin producing Escherichia coli (STEC that do not encode the locus of enterocyte effacement (LEE-negative STEC often possess Shiga toxin gene variants and have been isolated from humans and a variety of animal sources. In this study, we compare the genomes of nine LEE-negative STEC harboring various stx alleles with four complete reference LEE-positive STEC isolates. Compared to a representative collection of prototype E. coli and Shigella isolates representing each of the pathotypes, the whole genome phylogeny demonstrated that these isolates are diverse. Whole genome comparative analysis of the 13 genomes revealed that in addition to the absence of the LEE pathogenicity island, phage encoded genes including non-LEE encoded effectors, were absent from all nine LEE-negative STEC genomes. Several plasmid-encoded virulence factors reportedly identified in LEE-negative STEC isolates were identified in only a subset of the nine LEE-negative isolates further confirming the diversity of this group. In combination with whole genome analysis, we characterized the lambdoid phages harboring the various stx alleles and determined their genomic insertion sites. Although the integrase gene sequence corresponded with genomic location, it was not correlated with stx variant, further highlighting the mosaic nature of these phages. The transcription of these phages in different genomic backgrounds was examined. Expression of the Shiga toxin genes, stx1 and/or stx2, as well as the Q genes, were examined with quantitative reverse transcriptase polymerase chain reaction (qRT-PCR assays. A wide range of basal and induced toxin induction was observed. Overall, this is a first significant foray into the genome space of this unexplored group of emerging and divergent pathogens.

  9. Oxygen Consumption by Postfermentation Wine Yeast Lees: Factors Affecting Its Rate and Extent under Oenological Conditions

    Directory of Open Access Journals (Sweden)

    Jonas Müller

    2016-01-01

    Full Text Available Postfermentation wine yeast lees show antioxidant properties based on their ability to consume dissolved oxygen. The oxygen consumption capacity of suspended yeast lees obtained after fermentations with six commercial active dry yeast strains was investigated in model, white and red wines using fluorescence-based oxygen sensors operating in a nondestructive way. In model solution, the oxygen consumption rate of yeast lees was shown to depend on their amount, yeast strain, sulfur dioxide and temperature. It is slightly lower in red than in white wines. It is strongly decreased by current levels of free sulfur dioxide, thus excluding the complementary use of both as antioxidants in wine. However, in 25 randomly sampled white wines produced under commercial conditions, the rate and extent of oxygen consumption during the first six months of postfermentation had no significant correlation with any of these interacting factors, making it difficult to predict the actual antioxidant effect of yeast lees. In these wines, yeast lees consumed 0 to 47 % of the dissolved oxygen. Although total oxygen consumption capacity of yeast lees is not a limiting factor under commercial winemaking conditions, their oxygen consumption proceeds at a limited rate that reduces but cannot totally prevent concomitant chemical oxidation of the wine.

  12. The search for redemption: Julia Kristeva and Slavoj Žižek on Marx, psychoanalysis and religion

    Directory of Open Access Journals (Sweden)

    Boer Roland

    2007-01-01

    Full Text Available Slavoj Žižek and Julia Kristeva have followed strikingly similar paths in their intellectual and political development, moving from Marxism through psychoanalysis to Christianity. This article traces the way they have distanced themselves from Marxism and taken up psychoanalysis, of either the Freudian or Lacanian variety. For Kristeva, psychoanalysis provides the therapeutic solution to individual and at times social problems, whereas for Žižek it is the best description of those problems without necessarily providing answers. However, through psychoanalysis, they have gone a step further and become enamoured with Christianity, especially Paul’s letters in the New Testament and the doctrine of love. Paul provides for Kristeva another and earlier version of psychoanalytic solutions, but he enables Žižek to find the social and political answers for which he seeks. By connecting these intellectual moves with their own departures from Eastern Europe, one from Yugoslavia (and then Slovenia and the other from Bulgaria, I argue that their search for redemption, of both personal and social forms, betrays a residual socialism. In fact, their moves into psychoanalysis and Christianity may be read as compensations for a lost socialism, so much so that Žižek at least makes a belated recovery of Marx through Christianity and Kristeva can never quite excise Marx from her thought.

  13. Experiences of exclusion when living on a ventilator: reflections based on the application of Julia Kristeva's philosophy to caring science.

    Lindahl, Berit

    2011-01-01

    The research presented in this work represents reflections in the light of Julia Kristeva's philosophy concerning empirical data drawn from research describing the everyday life of people dependent on ventilators. It also presents a qualitative and narrative methodological approach from a person-centred perspective. Most research on home ventilator treatment is biomedical. There are a few published studies describing the situation of people living at home on a ventilator but no previous publications have used the thoughts in Kristeva's philosophy applied to this topic from a caring science perspective. The paper also addresses what a life at home on a ventilator may be like and will hopefully add some new aspects to the discussion of philosophical issues in nursing and the very essence of care. Kristeva's philosophy embraces phenomena such as language, abjection, body, and love, allowing her writings to make a fruitful contribution to nursing philosophy in that they strengthen, expand, and deepen a caring perspective. Moreover, her writings about revolt having the power to create hope add an interesting aspect to the work of earlier philosophers and nursing theorists. © 2010 Blackwell Publishing Ltd.

  14. "Teaching Physics as one of the humanities": The history of (harvard) project Physics, 1961-1970

    Science.gov (United States)

    Meshoulam, David

    In the United States after World War II, science had come to occupy a central place in the minds of policy makers, scientists, and the public. Negotiating different views between these groups proved a difficult task and spilled into debates over the role and scope of science education. To examine this process, this dissertation traces the history of Harvard Project Physics (HPP), a high-school physics curriculum from the 1960s that incorporated a humanistic and historical approach to teaching science. The narrative begins with the rise of General Education in the 1940s. Under the leadership of Harvard president James Conant, faculty at Harvard developed several Natural Science courses that connected science to history as a way to teach students about science and its relationship to culture. By the late 1950s this historical approach faced resistance from scientists who viewed it as misrepresenting their disciplines and called for students to learn specialized subject matter. With the support of the National Science Foundation (NSF), in the early 1960s scientists' vision of science education emerged in high-school classrooms across the country. By the mid 1960s, with the passage of the Civil Rights Act, the Elementary and Secondary Education Act, and the Daddario Amendment to the NSF, the political and education landscape began to change. These laws transformed the goals of two of the NSF and the Office of Education (USOE). These organizations faced demands to work together to develop projects that would speak to domestic concerns over equity and diversity. Their first joint educational venture was HPP. In order to succeed, HPP had to speak to the needs of disciplinary-minded scientists at the NSF, equity-minded educators at the USOE, and results-focused politicians in Congress. This work argues that HPP succeeded because it met the needs of these various stakeholders regarding the roles of science and education in American society.

    The Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) has not been explicitly tested on an adolescent population. In this study, the German version of the HGSHS:A was administered to 99 German adolescents aged 15 to 19. In contrast to other studies, the gender distribution was relatively balanced: 57% female and 43% male. Results were comparable to 14 earlier studies with regard to distribution, mean, and standard deviation. Some peculiarities in contrast to the 14 previous studies are pointed out. It is concluded that the HGSHS:A can be used as a valid and reliable instrument to measure hypnotic suggestibility in adolescent samples.

    The use of brachytherapy--and to a lesser extent, external-beam radiotherapy--in the management of locally recurrent breast cancer following ipsilateral breast tumor recurrence (IBTR) followed by repeat breast-conservation surgery and irradiation is currently an area of intense study. The current cosmetic scoring system is inadequate to score the outcome resulting from retreatment because it does not account for the cosmetic effect of the initial treatment. We propose a modification of the scale for patients who undergo retreatment--the Allegheny General Modification of the Harvard/NSABP/RTOG scoring scale.

    Harvard University has a growing astronomy program that offers various courses to the undergraduate concentrators, secondaries and non-majors. Many of the courses involve labs that use the 16-inch DFM Clay Telescope for night-time observations and the heliostat for observing the Sun. The goal is to proactively adapt the lab and telescope facilities to accommodate all students with disabilities. The current focus is converting the labs to accommodate visually impaired students. Using tactile images and sound, the intention is to create an experience equivalent to that of a student with full sight.

  19. Practicing psychology in the art gallery: Vernon Lee's aesthetics of empathy.

    Science.gov (United States)

    Lanzoni, Susan

    2009-01-01

    Late nineteenth-century psychologists and aestheticians were fascinated by the study of psychological and physiological aspects of aesthetic response, and the British intellectual and aesthete Vernon Lee was a major participant in this venture. Working outside the academy, Lee conducted informal experiments with Clementina Anstruther-Thomson, recording changes in respiration, balance, emotion, and body movements in response to aesthetic form. In fashioning her aesthetics of empathy, she mined a wealth of psychological theories of the period including motor theories of mind, physiological theories of emotion, evolutionary models of the usefulness of art, and, most prominently, the empathic projection of feeling and movement into form. Lee distributed questionnaires, contributed to scientific journals, carried out her own introspective studies, and debated aesthetics with leading psychologists. This paper critiques the prevailing view of Lee's aesthetics as a displaced sign of her gender or sexuality, and questions her status as simply an amateur in the field of psychology. Instead, I argue that Lee's empirically based empathy theory of art was a significant contribution to debates on psychological aesthetics at the outset of the twentieth century, offering a synthesis of Lipps's mentalistic Einfühlung and sensation-based imitation theories of aesthetic response.

    Biochar has great advantages in soil amendment and polluted soil remediation. Herein, the pore and adsorption properties of wine lees-derived biochar were explored. Specifically, the adsorption isotherm and kinetics of Pb(2+) onto wine lees-derived biochar were examined. Experimental results revealed that wine lees-derived biochar featured large specific surface area and total pore volume, and high contents of -COOH and -OH on its surface. Adsorption of Pb(2+) onto wine lees-derived biochar proceeded via a multilayer adsorption mechanism, as described by the Freundlich adsorption model. Adsorption kinetics followed the Lagergren pseudo-second-order kinetics model; adsorption equilibrium was achieved within 30-60 min. Furthermore, the effect of solution pH on the adsorption of Pb(2+) was investigated. Within the studied pH range of 3-6, the adsorption capacity increased with increasing pH. Under established optimized conditions, wine lees-derived biochar achieved a Pb(2+) adsorption capacity of 79.12 mg/g.

    This article examines the life of Lee Jungsook, a Korean nurse, as a independence activist during the Japanese colonial period. Lee Jungsook(1896-1950) was born in Bukchung in Hamnam province. She studied at Chungshin girl's high school and worked at Severance hospital. The characteristics and culture of her educational background and work place were very important factors which influenced greatly the life of Lee Jungsook. She learned independent spirit and nationalism from Chungshin girls' high school and worked as nurse at the Severance hospital which were full of intense aspiration for Korea's independence. Many of doctors, professors and medical students were participated in the 3.1 Independence Movement. Lee Jungsook was a founding member of Hyulsungdan who tried to help the independence activists in prison and their families and worked as a main member of Korean Women's Association for Korean Independece and Kyungsung branch of the Korean Red Cross. She was sent to jail by the Japanese government for her independence activism. After being released after serving two years confinement, she worked for the Union for Women's Liberation as a founding member. Lee Joungsook was a great independence activist who had a nursing care spirit as a nurse.

  2. Evolution of the New Pathway curriculum at Harvard Medical School: the new integrated curriculum.

    2011-01-01

    In 1985, Harvard Medical School adopted a "New Pathway" curriculum, based on active, adult learning through problem-based, faculty-facilitated small-group tutorials designed to promote lifelong skills of self-directed learning. Despite the successful integration of clinically relevant material in basic science courses, the New Pathway goals were confined primarily to the preclinical years. In addition, the shifting balance in the delivery of health care from inpatient to ambulatory settings limited the richness of clinical education in clinical clerkships, creating obstacles for faculty in their traditional roles as teachers. In 2006, Harvard Medical School adopted a more integrated curriculum based on four principles that emerged after half a decade of self-reflection and planning: (1) integrate the teaching of basic/population science and clinical medicine throughout the entire student experience; (2) reestablish meaningful and intensive faculty-student interactions and reengage the faculty; (3) develop a new model of clinical education that offers longitudinal continuity of patient experience, cross-disciplinary curriculum, faculty mentoring, and student evaluation; and (4) provide opportunities for all students to pursue an in-depth, faculty-mentored scholarly project. These principles of our New Integrated Curriculum reflect our vision for a curriculum that fosters a partnership between students and faculty in the pursuit of scholarship and leadership.

    The Harvard-MIT Research Program in Short-lived Radiopharmaceuticals was established in 1977 to foster interaction among groups working in radiopharmaceutical chemistry at Harvard Medical School, the Massachusetts Institute of Technology, and the Massachusetts General Hospital. To this was added a group at The Childrens Hospital. From these collaborations and building upon the special strengths of the participating individuals, laboratories and institutions, it was hoped that original approaches would be found for the design of new, clinically useful, radiolabeled compounds. The original thrust of this proposal included: (a) examination of the coordination chemistry of technetium as a basis for rational radiopharmaceutical design, (b) development of an ultrashort-lived radionuclide generator for the diagnosis of congenital heart disease in newborns, (c) synthesis of receptor-site-directed halopharmaceuticals, (d) improved facile labeling of complex molecules with positron-emitting radionuclides. The authors` 1986 proposal was oriented toward organs and disease, emphasizing radiolabeled agents that delineate specific functions and the distribution of receptors in brain, heart, and tumors. In 1989, they further refined their purposes and focused on two major aims: (a) synthesis and utilization of neutral technetium and rhenium complexes of high specific activity, and (b) development of new approaches to the radiolabeling of proteins, peptides, immunoglobulins, and their fragments. In 1992, the authors amended this proposal to concentrate their efforts on biologically active peptides and proteins for targeted radiodiagnosis and therapy.

    The Harvard Medical School Cambridge Integrated Clerkship is a longitudinal integrated clerkship that has provided an alternative clinical model for medical education in psychiatry since its inception in 2004. This study was undertaken in an effort to better understand the student experience of the Cambridge Integrated Clerkship and how it may have impacted students' perceptions of and interest in psychiatry, as well as performance. Qualitative surveys were sent via e-mail to the first 11 student cohorts who had completed the Cambridge Integrated Clerkship (from 2004 to 2014) and for whom we had e-mail addresses (N = 100), and the free-text responses were coded thematically. All available standardized scoring data and residency match data for Cambridge Integrated Clerkship graduates were obtained. From 2006 to 2014, 12 out of 73 Cambridge Integrated Clerkship students who entered the match chose a psychiatry residency (16.4%), four times more than students in traditional clerkships at Harvard Medical School (3.8% of 1355 students) or the national average (4.1% of 146,066 US applicants). Thirty of the 100 surveyed Cambridge Integrated Clerkship graduates (30%) responded to the qualitative survey with free-text remarks on a number of themes. Cambridge Integrated Clerkship students compared positively to their classmates in terms of standardized test performance. Their fourfold higher match rate into psychiatry compared to other students raises intriguing questions as to what role a longitudinal clerkship might have played in developing interest in psychiatry as a career.

  5. Does it really care? The Harvard report on health care reform for Hong Kong.

    Science.gov (United States)

    Po-wah, J T

    1999-12-01

    This paper aims to provide a rendition of the care ethic in Confucian philosophy and to argue that social policy developments in Hong Kong society, including health care policy, have been significantly shaped and justified in terms of the ideal of care in the Confucian moral tradition. On the basis of this analysis, the paper raises a number of questions about a recent proposal for health care reform for Hong Kong put forth by the Harvard School of Public Health which argues for adopting the principle of equity as the overriding value for the moral foundation of Hong Kong's health care system. The paper examines how the over-emphasis on equity in the Harvard Report proposals can lead to the erosion of care and ultimately the eclipse of the vision of care in Hong Kong's health care system. It argues that the pursuit of equity, which is itself a valuable principle, should not displace the importance of the value of care or undermine the ideal of care and that health care decisions must be firmly embedded in local cultures and moral traditions.

    2013-01-01

    The current research focuses on mesoscale dynamics of the atmospheric circulation around an idealized coastal cape representing typical summertime circulation along the northwest coast of the U.S., studied using a mesoscale coupled ocean-atmosphere modeling system. The orographic wind maximum features a strong NW flow extending a few hundred kilometers downstream and seaward of the cape, which closely follows mesoscale orographic low pressure developed in the lee of the cape. Both wind maximum and the lee trough experience a pronounced diurnal cycle, marked by maximum northwest flow and minimum pressure in the local evening hours (its opposite phase during morning hours), and confirmed by observations from limited buoy and coastal stations. Vertical structure of the atmospheric boundary layer over the coastal ocean on the lee side of the cape indicated the downward propagation of potential temperature and wind features during the course of the day, as opposed to the traditional surface-driven development of t...

  8. The Lee-Wick Extension of the Two-Higgs Doublet Model

    CERN Document Server

    Johansen, Aria R; Thrasher, Keith

    2015-01-01

    The Lee-Wick Standard Model is a highly constrained model which solves the gauge hierarchy problem at the expense of including fields with negative norm. It appears to be macroscopically causal and consistent. This model is extended by considering the two-Higgs doublet extension of the Lee-Wick model. Rewriting the Lagrangian using auxiliary fields introduces two additional doublets of Lee-Wick partners. The model is highly constrained, with only one or two additional parameters beyond that of the usual two-Higgs doublet model, and yet there are four doublets. Mass relations are established by diagonalizing the mass matrices and further constraints are established by studying results from B --> tau nu, neutral B-meson mixing, and B --> X_s gamma. The prospects of detecting evidence for this model at the LHC are discussed.

    that characterizes mortality data. We find empirical evidence that this feature of the Lee-Carter model overly restricts the system dynamics and we suggest to separate the deterministic and stochastic time series components at the benefit of improved fit and forecasting performance. In fact, we find...... as a two (or several)-factor model where one factor is deterministic and the other factors are stochastic. This feature generalizes to the range of models that extend the Lee-Carter model in various directions.......The Lee and Carter (1992) model assumes that the deterministic and stochastic time series dynamics loads with identical weights when describing the development of age specific mortality rates. Effectively this means that the main characteristics of the model simplifies to a random walk model...

    2014-08-01

    The Harvard Clinical and Translational Science Center ("Harvard Catalyst") Research Subject Advocacy (RSA) Program has reengineered subject advocacy, distributing the delivery of advocacy functions through a multi-institutional, central platform rather than vesting these roles and responsibilities in a single individual functioning as a subject advocate. The program is process-oriented and output-driven, drawing on the strengths of participating institutions to engage local stakeholders both in the protection of research subjects and in advocacy for subjects' rights. The program engages stakeholder communities in the collaborative development and distributed delivery of accessible and applicable educational programming and resources. The Harvard Catalyst RSA Program identifies, develops, and supports the sharing and distribution of expertise, education, and resources for the benefit of all institutions, with a particular focus on the frontline: research subjects, researchers, research coordinators, and research nurses.

  11. A modified Lee-Carter model for analysing short-base-period data.

    Zhao, Bojuan Barbara

    2012-03-01

    This paper introduces a new modified Lee-Carter model for analysing short-base-period mortality data, for which the original Lee-Carter model produces severely fluctuating predicted age-specific mortality. Approximating the unknown parameters in the modified model by linearized cubic splines and other additive functions, the model can be simplified into a logistic regression when fitted to binomial data. The expected death rate estimated from the modified model is smooth, not only over ages but also over years. The analysis of mortality data in China (2000-08) demonstrates the advantages of the new model over existing models.

    2015-02-01

    Reduction of duplicative Institutional Review Board (IRB) review for multiinstitutional studies is a desirable goal to improve IRB efficiency while enhancing human subject protections. Here we describe the Harvard Catalyst Master Reciprocal Common IRB Reliance Agreement (MRA), a system that provides a legal framework for IRB reliance, with the potential to streamline IRB review processes and reduce administrative burden and barriers to collaborative, multiinstitutional research. The MRA respects the legal autonomy of the signatory institutions while offering a pathway to eliminate duplicative IRB review when appropriate. The Harvard Catalyst MRA provides a robust and flexible model for reciprocal reliance that is both adaptable and scalable.

  15. Digitization Procedures of Analogue Seismograms from the Adam Dziewonski Observatory (HRV) at Harvard, MA

    Torpey, M.; Ishii, M.

    2010-12-01

    This project explores methods of digitization of analogue seismic recordings for better preservation and to facilitate data distribution to the community. Different techniques are investigated using seismograms from one particular station, the Adam Dziewonski Observatory (HRV) at Harvard, Massachusetts. This seismological station, still in operation as a part of the Global Seismographic Network today, is one of the oldest stations in the United States. The station was built in 1933, and since its installation, the station has produced approximately 16,000 analogue seismograms. The majority of these recordings were taken between 1933 and 1953, with some intermittent recordings between 1962 and 1998 after digital seismometers had become a standard. These analogue seismograms have the potential of expanding the database for seismological research such as identification of events previously not catalogued. Due to poor storage environment at the station, some of the records, especially those on regular type of paper, are damaged beyond repair. Nevertheless, many of the records on photographic paper are in better condition, and we have focused on a subset of these recordings that are least damaged. Even these seismograms require cleaning and, in consultation with the Weissman Preservation Center of Harvard Library, preparation techniques for the photographic records are examined. After the seismograms are cleaned and flattened, three different equipments are investigated for digitization, i.e., a copy machine, scanner, and camera. These instruments allow different imaging resolutions, ranging from 200 dots per inch (dpi) to 800 dpi. The image resolution and the bit depth have a wide range of implications that are closely linked to the digitization program one chooses to convert the image to time series. We explore three different software for this conversion, SeisDig (Bromirski and Chuang, 2003), Teseo2 (Pintore and Quintiliani, 2008), and NeuraLog (www

    2009-10-15

    Beer lees are the main by-product of the brewing industry. Biohydrogen production from beer lees using anaerobic mixed bacteria was investigated in this study, and the effects of acidic pretreatment, initial pH value and ferrous iron concentration on hydrogen production were studied at 35 C in batch experiments. The hydrogen yield was significantly enhanced by optimizing environmental factors such as hydrochloric acid (HCl) pretreatment of substrate, initial pH value and ferrous iron concentration. The optimal environmental factors of substrate pretreated with 2% HCl, pH = 7.0 and 113.67 mg/l Fe{sup 2+} were observed. A maximum cumulative hydrogen yield of 53.03 ml/g-dry beer lees was achieved, which was approximately 17-fold greater than that in raw beer lees. In addition, the degradation efficiency of the total reducing sugar, and the contents of hemicellulose, cellulose, lignin and metabolites are presented, which showed a strong dependence on the environmental factors.

  13. Unitarity, Lorentz invariance and causality in Lee-Wick theories: An asymptotically safe completion of QED

    CERN Document Server

    van Tonder, André

    2008-01-01

    We revisit the previously unsolved problems of ensuring Lorentz invariance and non-perturbative unitarity in Lee-Wick theories. We base our discussion on an ultraviolet completion of QED by Lee-Wick ghost fields, which is argued to be asymptotically safe. We argue that as long as the state space is based upon a suitable choice of distributions of a type invented by Gel'fand and Shilov, the Lee-Wick ghosts can be eliminated while preserving Lorentz invariance to produce a unitary theory. The method for eliminating ghosts is in principle non-perturbatively well-defined, in contrast with some previous proposals. We also point out a second, independent mechanism for producing a unitary theory, based on a covariant constraint on the maximum four-momentum, which would imply an amusing connection, based on naturalness, between the coupling constant and the hierarchy of scales in the theory. We further emphasize that the resulting theory is causal, and point out some analogies between between the behaviour of Lee-Wic...

  19. Lee-Yang-Fisher zeros for DHL and 2D rational dynamics, II. Global Pluripotential Interpretation

    CERN Document Server

    Bleher, Pavel; Roeder, Roland

    2011-01-01

    In a classical work of the 1950's, Lee and Yang proved that for fixed nonnegative temperature, the zeros of the partition functions of a ferromagnetic Ising model always lie on the unit circle in the complex magnetic field. Zeros of the partition function in the complex temperature were then considered by Fisher, when the magnetic field is set to zero. Limiting distributions of Lee-Yang and of Fisher zeros are physically important as they control phase transitions in the model. One can also consider the zeros of the partition function simultaneously in both complex magnetic field and complex temperature. They form an algebraic curve called the Lee-Yang-Fisher (LYF) zeros. In this paper we study their limiting distribution for the Diamond Hierarchical Lattice (DHL). In this case, it can be described in terms of the dynamics of an explicit rational function $R$ in two variables (the Migdal-Kadanoff renormalization transformation). We prove that the Lee-Yang-Fisher zeros are equidistributed with respect to a dyn...

  5. Multifractal Omori-Utsu Law for Earthquake Triggering: New Tests on the Harvard and Japanese Catalogs

    CERN Document Server

    Ouillon, G; Sornette, D

    2006-01-01

    The Multifractal Stress-Activated (MSA) model is a statistical model of triggered seismicity based on mechanical and thermodynamic principles. It predicts that, above a triggering magnitude cut-off $M_0$, the exponent $p$ of the Omori-Utsu law for the seismic decay of aftershocks is a linear increasing function $p(M) =a M+b$ of the mainshock magnitude $M$ [Ouillon and Sornette, 2005]. First empirical support for this prediction has been presented for the Southern California SCEC catalog. Here, we confirm this law on the worlwide Harvard CMT and the Japanese JMA catalogs, with similar ranges of variation from $p(M=3)=0.7 \\pm 0.1$ to $p(M=8)=1.1 \\pm 0.2$. However, the statistically significant differences of the slopes $a$, intercepts $b$ and cut-offs $M_0$ suggest different multifractal properties of the three catalogs, likely associated with different thermal and mechanical properties.

    2014-12-01

    Trauma exposure contributes to poor mental health among refugees, and exposure often is measured using a cumulative index of items from the Harvard Trauma Questionnaire (HTQ). Few studies, however, have asked whether trauma subtypes derived from the HTQ could be superior to this cumulative index in predicting mental health outcomes. A community sample of recently arrived Iraqi refugees (N = 298) completed the HTQ and measures of posttraumatic stress disorder (PTSD) and depression symptoms. Principal components analysis of HTQ items revealed a 5-component subtype model of trauma that accounted for more item variance than a 1-component solution. These trauma subtypes also accounted for more variance in PTSD and depression symptoms (12 and 10%, respectively) than did the cumulative trauma index (7 and 3%, respectively). Trauma subtypes provided more information than cumulative trauma in the prediction of negative mental health outcomes. Therefore, use of these subtypes may enhance the utility of the HTQ when assessing at-risk populations.

    Hungarian norms for the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) are presented. The Hungarian translation of the HGSHS:A was administered under standard conditions to 434 participants (190 males, 244 females) of several professions. In addition to the traditional self-scoring, hypnotic behavior was also recorded by trained observers. Female participants proved to be more hypnotizable than males and so were psychology students and professionals as compared to nonpsychologists. Hypnotizability varied across different group sizes. The normative data-including means, standard deviations, and indicators of reliability-are comparable with previously published results. The authors conclude that measuring observer-scores increases the ecological validity of the scale. The Hungarian version of the HGSHS:A seems to be a reliable and valid measure of hypnotizability.

    The Portuguese version of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) was administered to 313 Portuguese college students. Score distribution, item pass rates, item analysis, and reliability of the HGSHS:A are presented and compared to earlier published reference samples. No differences were found between males and females. Reliability of the HGSHS:A Portuguese version was lower than that reported by most of the studies but within the range of the non-English versions. In general, Portuguese data are congruent with the reference samples and the Portuguese translation of the HGSHS:A. It appears to be a viable instrument for primary screening of hypnotic suggestibility in a Portuguese context.

    2016-01-01

    Full Text Available The number of refugees and asylum seekers in Serbia is significantly increasing. Many have experienced traumatic events and suffer from posttraumatic stress disorder and depression. In order to provide them with adequate assistance, caregivers need adjusted assessment tools. The main goal of this research was the adaptation of the Harvard Trauma Questionnaire for working with refugees and asylum seekers in Serbia. A total of 16 focus groups were interviewed in two phases in order to create an adequate list of traumatic events for this population. The adapted list was subsequently administered to 226 persons seeking asylum in Serbia, along with the remaining parts of HTQ, HSCL-25 and BDI-II. Results show that the adapted list of traumatic events, as well as a shorter version, has good validity and other metric properties. The adaptation of the first assessment tool for working with refugees and asylum seekers in Serbia has significant practical implications.

    Earthquake is the best information source for describing the present-day crustal tectonic zones and crustal stress field, containing comprehensive and abundant geodynamic connotations.Based on the distribution of global earthquakes and their kinematic and dynamic characteristics, the most active global-scale tectonics can be divided into three first-order tectonic systems: the Circum-Pacific deep subduction tectonic system, the mid-oceanic ridge tectonic system, and the continent-continent shallow underthrusting tectonic system using the Harvard CMT catalogue that provides various parameters of hypocenter. Furthermore, the differences of fault types, seismicity, and distribution of focal depths in different tectonic systems are discussed as well. The results show that different tectonic system possesses different environment and geodynamics.

    Many graduates of the Harvard Medical Unit (HMU) at Boston City Hospital, in either the clinical training/residency program or the research program at the Thorndike Memorial Laboratory, contributed in major ways to the HMU and constantly relived their HMU experiences. The HMU staff physicians, descending from founder and mentor physicians Francis W. Peabody, Soma Weiss, and George R. Minot, were dedicated to the teaching, development, and leadership of its clinical and research trainees, whose confidence and dedication to patient care as a result of their mentorship led many to lifelong achievements as clinicians, teachers, and mentors. Their experience also led to a lifelong love of the HMU (despite its loss), camaraderie, happiness, and intense friendships with their associates.

    Model simulation and in situ observation are the two most important means in studying the water and carbon cycles of terrestrial ecosystems, but have their own advantages and shortcomings. To combine these two means would help to reflect the dynamic changes of ecosystem water and carbon fluxes more accurately. Data assimilation provides an effective way to integrate the model simulation and in situ observation. Based on the observation data from the Harvard Forest Environmental Monitoring Site (EMS), and by using ensemble Kalman Filter algorithm, this paper assimilated the field measured LAI and remote sensing LAI into the Biome-BGC model to simulate the water and carbon fluxes in Harvard forest area. As compared with the original model simulated without data assimilation, the improved Biome-BGC model with the assimilation of the field measured LAI in 1998, 1999, and 2006 increased the coefficient of determination R2 between model simulation and flux observation for the net ecosystem exchange (NEE) and evapotranspiration by 8.4% and 10.6%, decreased the sum of absolute error (SAE) and root mean square error (RMSE) of NEE by 17.7% and 21.2%, and decreased the SAE and RMSE of the evapotranspiration by 26. 8% and 28.3%, respectively. After assimilated the MODIS LAI products of 2000-2004 into the improved Biome-BGC model, the R2 between simulated and observed results of NEE and evapotranspiration was increased by 7.8% and 4.7%, the SAE and RMSE of NEE were decreased by 21.9% and 26.3%, and the SAE and RMSE of evapotranspiration were decreased by 24.5% and 25.5%, respectively. It was suggested that the simulation accuracy of ecosystem water and carbon fluxes could be effectively improved if the field measured LAI or remote sensing LAI was integrated into the model.

  14. Limited effect of ozone reductions on the 20-year photosynthesis trend at Harvard forest.

    Ozone (O3 ) damage to leaves can reduce plant photosynthesis, which suggests that declines in ambient O3 concentrations ([O3 ]) in the United States may have helped increase gross primary production (GPP) in recent decades. Here, we assess the effect of long-term changes in ambient [O3 ] using 20 years of observations at Harvard forest. Using artificial neural networks, we found that the effect of the inclusion of [O3 ] as a predictor was slight, and independent of O3 concentrations, which suggests limited high-frequency O3 inhibition of GPP at this site. Simulations with a terrestrial biosphere model, however, suggest an average long-term O3 inhibition of 10.4% for 1992-2011. A decline of [O3 ] over the measurement period resulted in moderate predicted GPP trends of 0.02-0.04 μmol C m(-2)  s(-1)  yr(-1) , which is negligible relative to the total observed GPP trend of 0.41 μmol C m(-2)  s(-1)  yr(-1) . A similar conclusion is achieved with the widely used AOT40 metric. Combined, our results suggest that ozone reductions at Harvard forest are unlikely to have had a large impact on the photosynthesis trend over the past 20 years. Such limited effects are mainly related to the slow responses of photosynthesis to changes in [O3 ]. Furthermore, we estimate that 40% of photosynthesis happens in the shade, where stomatal conductance and thus [O3 ] deposition is lower than for sunlit leaves. This portion of GPP remains unaffected by [O3 ], thus helping to buffer the changes of total photosynthesis due to varied [O3 ]. Our analyses suggest that current ozone reductions, although significant, cannot substantially alleviate the damages to forest ecosystems. © 2016 John Wiley & Sons Ltd.

    Julia Ching is a brilliant, productive and outstanding Canadian- Chinese scholar, religion expert and philosopher. Julia Ching defined that religion is the belief in god and the efforts of self - transcendence, and she thought that Chinese religion has the characteristics of harmonicity, and it includes not only Confucianism, Taoism and Buddhism, but also the crazy primitive religions. This pluralistic religious thought and multi - religious participation concept is beneficial to the self- development of religions, the resolution of the conflicts between world religions, and dialogue and integration of religions.%秦家懿是一位成就卓著的加拿大籍华裔学者、宗教学家和哲学家。她将宗教界定为对神的信仰和自我超越的努力,认为中国宗教不仅包括儒学,道教和佛教,还包括狂热的原始宗教,具有调和性的特点。这是一种多元主义宗教观和多种宗教参与观,对宗教的自我发展、化解世界宗教间冲突,以及促进彼此对话和融合是一种行之有效的方法。

    A highly modular approach to N-substituted 4-(1-fluorovinyl)triazoles is described. In situ desilylation and Cu-catalyzed ligation reaction of TMS-protected α-fluoropropargyl benzothiazole sulfone with aryl, alkyl, and metallocenyl azides furnished second-generation Julia-Kocienski reagents in good to excellent yields. Condensation reactions of these reagents with aldehydes can be tuned to yield E or Z-alkenes selectively. Under mild conditions with DBU as the base, reactions of aldehydes furnished E-alkenes as the major isomer. On the other hand, in condensation reactions with LHMDS as the base and in appropriate solvents, both aldehydes and ketones reacted to yield fluoroalkenes with Z-selectivity. Stereochemical assignment of E/Z olefins obtained in the reaction of a ketone with two Julia reagents was performed via X-ray crystallographic analysis and comparisons of NMR data. The method allows efficient and ready diversification of the N1-substituent and substituents at the double bond.

  20. Bacterial-Chromatin Structural Proteins Regulate the Bimodal Expression of the Locus of Enterocyte Effacement (LEE Pathogenicity Island in Enteropathogenic Escherichia coli

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available In enteropathogenic Escherichia coli (EPEC, the locus of enterocyte effacement (LEE encodes a type 3 secretion system (T3SS essential for pathogenesis. This pathogenicity island comprises five major operons (LEE1 to LEE5, with the LEE5 operon encoding T3SS effectors involved in the intimate adherence of bacteria to enterocytes. The first operon, LEE1, encodes Ler (LEE-encoded regulator, an H-NS (nucleoid structuring protein paralog that alleviates the LEE H-NS silencing. We observed that the LEE5 and LEE1 promoters present a bimodal expression pattern, depending on environmental stimuli. One key regulator of bimodal LEE1 and LEE5 expression is ler expression, which fluctuates in response to different growth conditions. Under conditions in vitro considered to be equivalent to nonoptimal conditions for virulence, the opposing regulatory effects of H-NS and Ler can lead to the emergence of two bacterial subpopulations. H-NS and Ler share nucleation binding sites in the LEE5 promoter region, but H-NS binding results in local DNA structural modifications distinct from those generated through Ler binding, at least in vitro. Thus, we show how two nucleoid-binding proteins can contribute to the epigenetic regulation of bacterial virulence and lead to opposing bacterial fates. This finding implicates for the first time bacterial-chromatin structural proteins in the bimodal regulation of gene expression.

    Full Text Available A regional overview of the water quality and ecology of the River Lee catchment is presented. Specifically, data describing the chemical, microbiological and macrobiological water quality and fisheries communities have been analysed, based on a division into river, sewage treatment works, fish-farm, lake and industrial samples. Nutrient enrichment and the highest concentrations of metals and micro-organics were found in the urbanised, lower reaches of the Lee and in the Lee Navigation. Average annual concentrations of metals were generally within environmental quality standards although, on many occasions, concentrations of cadmium, copper, lead, mercury and zinc were in excess of the standards. Various organic substances (used as herbicides, fungicides, insecticides, chlorination by-products and industrial solvents were widely detected in the Lee system. Concentrations of ten micro-organic substances were observed in excess of their environmental quality standards, though not in terms of annual averages. Sewage treatment works were the principal point source input of nutrients, metals and micro-organic determinands to the catchment. Diffuse nitrogen sources contributed approximately 60% and 27% of the in-stream load in the upper and lower Lee respectively, whereas approximately 60% and 20% of the in-stream phosphorus load was derived from diffuse sources in the upper and lower Lee. For metals, the most significant source was the urban runoff from North London. In reaches less affected by effluent discharges, diffuse runoff from urban and agricultural areas dominated trends. High microbiological content, observed in the River Lee particularly in urbanised reaches, was far in excess of the EC Bathing Water Directive standards. Water quality issues and degraded habitat in the lower reaches of the Lee has led to impoverished aquatic fauna but, within the mid-catchment reaches and upper agricultural tributaries, less nutrient enrichment and channel

Firstly, the ideas on a changed view of the deity are discussed. This conversation is augmented by a discussion of the criticism levelled at the idea that reading the Bible has consequences for other people, and that a different reading would lead to a different concept of God. Van Deventer�s comments regarding the difficulty of debating theological issues are strengthened by a critical discussion of a debate in Die Kerkblad regarding the grammatical-historical method. His critical remarks regarding the value of a historical consciousness are discussed by way of a question on the relationship between a liberal theology and a conservative political point of view. Le Roux�s struggle with Snyman�s utilisation of apartheid as a rhetorical strategy leads the discussion to a recent example of overcoming racism while using unreflectingly racist imagery. This example indicates how theology effects cosmetic changes, without taking on the real issue. For this reason, the author concludes that a critical reading of the own Western tradition in Africa has become necessary.�--- Abstract translated into Sipedi ---Go bala, go bona, go bolela le go dumela ka go fapana - go arabela go balwa ga 'Om die Bybel anders te lees: �n Etiek van Bybellees' ke babadi ba bangweBjale ka ge go fetleka Bibele go etwa pele ke ditumelo t�a go tiba t�a teologi, mongwadi wa Om die Bybel anders te lees: �n Etiek van Bybellees (2007 o arabela ditsholo t�a puku ye t�eo di tswet�wego ke seminare ye e fetilego - kudu ditshwayotshwayo

    The ~500,000 Harvard glass plate photographic negatives are the world’s largest and most complete (full sky; 107y time span) database for Time Domain Astronomy (TDA) on days-months-decades to century timescales. With plate fields of view ranging from 3o - 30o exposed quasi-randomly full sky from 1885 - 1992, any object is observed ~1000 - 3000 times, with limiting magnitudes ranging from B =12-18. I briefly review some of the colorful history of this massive plate-taking project and a few of the pivotal discoveries (e.g. the “Leavitt Law” for the Cepheid Period-Luminosity relation) made by visual studies of the plates by the true TDA pioneers, the likely Harvard (DASCH) project to fully digitize and reduce this wealth of data 1 Pb) and provide it on spinning disk to the full astronomical community and public. Using the full-sky APASS catalog giving BVR magnitudes (for V ~9-17) as well as GSC2.3.2 for both fainter and brighter stars, DASCH does spatially resolved (0.25o -0.6o bins) photometric calibrations to derive B magnitudes with rm 0.1mag over the full plate and over the (typically) ~6-8 different principal plate series (telescopes and plate scales) covering any given object, along with ~0.3-1 arcsec astrometry (depending on plate scale) for each stellar object averaged over ~1year. The high speed/precision scanner, plate processing, and analysis pipeline have now enabled the first data releases (DR1-DR3) of 12 to cover full sky and already enabled a wealth of new discoveries. I describe a few examples, such as: K2III giants with decadal variations; a new class of Symbiotic novae; ~50-100y recurrence times for black hole X-ray binary outbursts; and QPOs from 3C273. The DASCH data are increasingly available 15% now; 100% in 3.5y) for TDA on largely unexplored timescales. We are grateful to NSF for support with grants AST-0407380, AST-0909073 and AST-1313370.

  4. Dynamical fragmentation of flux tubes in the Friedberg-Lee model

    1997-02-01

    We present two novel dynamical features of flux tubes in the Friedberg-Lee model. First the fusion of two (anti-)parallel flux tubes, where we extract a string-string interaction potential which has a qualitative similarity to the nucleon-nucleon potential in the Friedberg-Lee model obtained by Koepf et al. Furthermore we show the dynamical breakup of flux tubes via q overlineq- particle production and the disintegration into mesons. We find, as a shortcoming of the present realization of the model, that the full dynamical transport approach presented in a previous publication fails to provide the disintegration mechanism in the semiclassical limit. Therefore, in addition, we present here a molecular dynamical approach for the motion of the quarks and show, as a first application, the space-time development of the wuarks and their mean-fields for Lund-type string fragmentation processes.

The analysis of the data indicates experimental accessibility of the critical exponent {mu} of the Yang-Lee edge singularities. They manifest themselves in divergences of the density functions g({theta}), which quantify the distribution of the zeros of the partition function on the Lee-Yang unit circle in the complex plane. In accordance with the hypothesis of universality, a critical exponent close to the theoretical prediction for the two-dimensional Ising ferromagnet, {mu}=-1/6, is found. (author).

    Sparkling wines (SW) have a special biological ageing on lees that is performed using two distinct methods: in the bottle (Champenoise) or in isobaric tanks (Charmat method). The objective of this study was to compare the levels of phenolic compounds, β-Glucosidase and antioxidant activity during the ageing on lees, in samples of SW produced at industrial scale by both methods. The β-Glucosidase activity has been constant over time, showing a close relationship with all the polyphenols studied (resveratrol, piceid, tyrosol, gallic, caffeic and ferulic acids), which were affected by the sur lie time. With these cross-reactions, the biological properties of the SW were also modulated. The results showed that the long period of ageing decreased the antioxidant potential in all samples. This work demonstrates that the sur lie is more important than the production method itself, due to its ability to modulate the necessary changes to achieve the specific objective.

    We have discussed the vacuum tunnelling in Friedberg-Lee model. The tunnelling coefficient is derived in the field configuration space by calculating the transition amplitude using the path integral under the stationary phase approximation and the dilute instanton gas approximation. By studying the tunnelling effect between the two degenerating vacuums at the critical temperature and chemical potential, we find that the system could be deconfined by tunnelling, which could possibly change the first order deconfinement phase transition to crossover.

    The Friedberg-Lee (FL) model is studied at finite temperature and density. The soliton solutions of the FL model in the deconfinement phase transition are solved and thoroughly discussed for certain boundary conditions. We indicate that the solitons before and after the deconfinement have different physical meanings: the soliton before deconfinement represents hadrons, while the soliton after the deconfinement represents the bound state of quarks which leads to a strongly interacting quark-gluon plasma phase. The corresponding phase diagram is given.

In the frame of functional renormalization group, we extend the often used potential expansion method for continuous phase transitions to the first-order phase transition in the model. By solving the flow equations we find that, the magnetic field displays a catalysis effect and it becomes more difficult to break through the confinement in hot and dense medium.

In this scenario, the phenomenology, including effective neutrino masses, mixings, and thermal flavor-dependent leptogenesis and lepton flavor violation decays are studied. We investigate the combined constrain of the parameters in this scenario and test its consistency with present data.

    2017-04-01

    In the 1960-70s, South Korea was still in the position of a science latecomer. Although the scientific research environment in South Korea at that time was insufficient, there was a scientist who achieved outcomes that could be recognized internationally while acting in South Korea. He was Ho Wang Lee(1928~ ) who found Hantann Virus that causes epidemic hemorrhagic fever for the first time in the world. It became a clue to identify causative viruses of hemorrhagic diseases that were scattered here and there throughout the world. In addition, these outcomes put Ho Wang Lee on the global center of research into epidemic hemorrhagic fever. This paper examines how a Korean scientist who was in the periphery of virology could go into the central area of virology. Also this article shows the process through which the virus found by Ho Wang Lee was registered with the international academia and he proceeded with follow-up research based on this progress to reach the level at which he generalized epidemic hemorrhagic fever related studies throughout the world. While he was conducting the studies, experimental methods that he had never experienced encountered him as new difficulties. He tried to solve the new difficulties faced in his changed status through devices of cooperation and connection. Ho Wang Lee's growth as a researcher can be seen as well as a view of a researcher that grew from a regional level to an international level and could advance from the area of non-mainstream into the mainstream. This analytic tool is meaningful in that it can be another method of examining the growth process of scientists in South Korea or developing countries.

    Mountain lee waves have been previously observed in data from the Moderate Resolution Imaging Spectroradiometer (MODIS) "water vapor" 6.7 micrometers channel which has a typical peak sensitivity at 550 hPa in the free troposphere. This paper reports the first observation of mountain waves generated by the Appalachian Mountains in the MODIS total column water vapor (CWV) product derived from near-infrared (NIR) (0.94 micrometers) measurements, which indicate perturbations very close to the surface. The CWV waves are usually observed during spring and late fall or some summer days with low to moderate CWV (below is approx. 2 cm). The observed lee waves display wavelengths from3-4 to 15kmwith an amplitude of variation often comparable to is approx. 50-70% of the total CWV. Since the bulk of atmospheric water vapor is confined to the boundary layer, this indicates that the impact of thesewaves extends deep into the boundary layer, and these may be the lowest level signatures of mountain lee waves presently detected by remote sensing over the land.

    The effect of different treatments involving contact with natural lees on the aromatic profile of cider has been evaluated. Comparing with the untreated ciders, the contact with lees brought about a significant increase of the concentrations of most of the volatile compounds analysed, in particular fatty acids, alcohols, ethyl esters and 3-ethoxy-1-propanol. The opposite was observed among fusel acetate esters and 4-vinylguaiacol. The addition of β-glucanase enhanced the increase of ethyl octanoate, but produced a decrease in the contents of decanoic acid and all of the major volatiles excepting acetaldehyde, ethyl acetate and acetoine, whereas the application of oxygen influenced the rise of the level of 3-ethoxy-1-propanol only. The olfactometric profiles also revealed significant effects of the treatment with lees for ethyl propionate, diacetyl, cis-3-hexenol, acetic acid, benzyl alcohol, and m-cresol, while the addition of oxygen significantly influenced the perception of ethyl hexanoate, 1-octen-3-one, 3-methyl-2-butenol, t-3-hexenol and c-3-hexenol.

    Very recently, the Lee-Wick standard model has been introduced as a non-SUSY extension of the Standard model which solves the Hierarchy problem. In this model, each field kinetic term attains a higher derivative term. Like any Lee-Wick theory, this model suffers from existence of Ghost states. In this work, we consider a prototype scalar field theory with its kinetic term has a higher derivative term, which mimics the scalar sector in the Lee-Wick Standard model. We introduced an imaginary auxiliary field to have an equivalent non-Hermitian two-field scalar field theory. We were able to calculate the positive definite metric operator in quantum mechanical and quantum field versions of the theory in a closed form. The obtained metric operator also diagonalize the Hamiltonian in the two fields (no mixing). Moreover, its Hermiticity constrained the two Higgs masses to be related as $M>2m$, which has been obtained in another work using a very different regime and thus supports our calculation. Besides, the equiva...

    Improvement in life expectancies has driven further declines in mortality. The sustained reduction in mortality rates and its systematic underestimation has been attracting the significant interest of researchers in recent years because of its potential impact on population size and structure, social security systems, and (from an actuarial perspective) the life insurance and pensions industry worldwide. Among all forecasting methods, the Lee-Carter model has been widely accepted by the actuarial community and Heligman-Pollard model has been widely used by researchers in modelling and forecasting future mortality. Therefore, this paper only focuses on Lee-Carter model and Heligman-Pollard model. The main objective of this paper is to investigate how accurately these two models will perform using Malaysian data. Since these models involves nonlinear equations that are explicitly difficult to solve, the Matrix Laboratory Version 8.0 (MATLAB 8.0) software will be used to estimate the parameters of the models. Autoregressive Integrated Moving Average (ARIMA) procedure is applied to acquire the forecasted parameters for both models as the forecasted mortality rates are obtained by using all the values of forecasted parameters. To investigate the accuracy of the estimation, the forecasted results will be compared against actual data of mortality rates. The results indicate that both models provide better results for male population. However, for the elderly female population, Heligman-Pollard model seems to underestimate to the mortality rates while Lee-Carter model seems to overestimate to the mortality rates.

    Recent proton dosimetry intercomparisons have demonstrated that the adoption of a common protocol, e.g. ICRU Report 59, can lead to improved consistency in absorbed dose determinations. We compared absorbed dose values, measured in the 160 MeV proton radiosurgery beamline at the Harvard Cyclotron Laboratory, based on ionization chamber methods with those from a Faraday cup technique. The Faraday cup method is based on a proton fluence determination that allows the estimation of absorbed dose with the CEMA approximation, under which the dose is equal to the fluence times the mean mass stopping power. The ionization chamber technique employs an air-kerma calibration coefficient for {sup 60}Co radiation and a calculated correction in order to take into account the differences in response to {sup 60}Co and proton beam radiations. The absorbed dose to water, based on a diode measurement calibrated with a Faraday cup technique, is approximately 2% higher than was obtained from an ionization chamber measurement. At the Bragg peak depth, the techniques agree to within their respective uncertainties, which are both approximately 4% (1 standard deviation). The ionization chamber technique exhibited superior reproducibility and was adopted in our standard clinical practice for radiosurgery. (author)

  9. Incorporating Language Leaming Into the Academic Setting: A Practical Example at Harvard University

    Full Text Available There has been a growing interest in the learning of African languages in US institutions in recent years. Students learn these languages for various reasons: to fulfill academic requirements, to connect with their heritage, to undertake academic research and learn to help them understand materials in an academic course they are taking. To make this process meaningful to learners, there is a need to integrate language learning into academic disciplines. However, this is one area which has received little attention in an African language syllabus at the university level. There abound areas in African language learning which can be made meaningful to its students within the university academic arena. This paper describes how the African Languages Program at Harvard University collaborated with a professor of Anthropology to teach the course Delimiting health disparities in the African Diaspora: A Laboratory for social Engagement. This involved twenty-two students in three African languages (Akan -Twi, Dinka, and W olof as well as Haitian Creole.

    At the Harvard Forest, Petersham, MA, the impact of 20 years of annual ammonium nitrate application to the mixed hardwood stand on soil bacterial communities was studied using 16S rRNA genes pyrosequencing. Amplification of 16S rRNA genes was done using DNA extracted from 30 soil samples (three treatments × two horizons × five subplots) collected from untreated (control), low N-amended (50 kg ha(-1) year(-1)) and high N-amended (150 kg ha(-1) year(-1)) plots. A total of 1.3 million sequences were processed using qiime. Although Acidobacteria represented the most abundant phylum based on the number of sequences, Proteobacteria were the most diverse in terms of operational taxonomic units (OTUs). UniFrac analyses revealed that the bacterial communities differed significantly among soil horizons and treatments. Microsite variability among the five subplots was also evident. Nonmetric multidimensional scaling ordination of normalized OTU data followed by permutational manova further confirmed these observations. Richness indicators and indicator species analyses revealed higher bacterial diversity associated with N amendment. Differences in bacterial diversity and community composition associated with the N treatments were also observed at lower phylogenetic levels. Only 28-35% of the 6 936 total OTUs identified were common to three treatments, while the rest were specific to one treatment or common to two.

    The Harvard Lakes 1:24,000-scale quadrangle spans the Arkansas River Valley in central Colorado, and includes the foothills of the Sawatch Range on the west and Mosquito Range on the east. The Arkansas River valley lies in the northern end of the Rio Grande rift and is structurally controlled by Oligocene and younger normal faults mostly along the west side of the valley. Five separate pediment surfaces were mapped, and distinctions were made between terraces formed by the Arkansas River and surfaces that formed from erosion and alluviation that emanated from the Sawatch Range. Three flood deposits containing boulders as long as 15 m were deposited from glacial breakouts just north of the quadrangle. Miocene and Pliocene basin-fill deposits of the Dry Union Formation are exposed beneath terrace or pediment deposits in several places. The southwestern part of the late Eocene Buffalo Peaks volcanic center, mostly andesitic breccias and flows and ash-flow tuffs, occupy the northeastern corner of the map. Dated Tertiary intrusive rocks include Late Cretaceous or early Paleocene hornblende gabbro and hornblende monzonite. Numerous rhyolite and dacite dikes of inferred early Tertiary or Late Cretaceous age also intrude the basement rocks. Basement rocks are predominantly Mesoproterozoic granites, and subordinately Paleoproterozoic biotite gneiss and granitic gneiss.

    This article is an update of the algorithm for schizophrenia from the Psychopharmacology Algorithm Project at the Harvard South Shore Program. A literature review was conducted focusing on new data since the last published version (1999-2001). The first-line treatment recommendation for new-onset schizophrenia is with amisulpride, aripiprazole, risperidone, or ziprasidone for four to six weeks. In some settings the trial could be shorter, considering that evidence of clear improvement with antipsychotics usually occurs within the first two weeks. If the trial of the first antipsychotic cannot be completed due to intolerance, try another until one of the four is tolerated and given an adequate trial. There should be evidence of bioavailability. If the response to this adequate trial is unsatisfactory, try a second monotherapy. If the response to this second adequate trial is also unsatisfactory, and if at least one of the first two trials was with risperidone, olanzapine, or a first-generation (typical) antipsychotic, then clozapine is recommended for the third trial. If neither trial was with any these three options, a third trial prior to clozapine should occur, using one of those three. If the response to monotherapy with clozapine (with dose adjusted by using plasma levels) is unsatisfactory, consider adding risperidone, lamotrigine, or ECT. Beyond that point, there is little solid evidence to support further psychopharmacological treatment choices, though we do review possible options.

    This revision of previous algorithms for the pharmacotherapy of generalized anxiety disorder was developed by the Psychopharmacology Algorithm Project at the Harvard South Shore Program. Algorithms from 1999 and 2010 and associated references were reevaluated. Newer studies and reviews published from 2008-14 were obtained from PubMed and analyzed with a focus on their potential to justify changes in the recommendations. Exceptions to the main algorithm for special patient populations, such as women of childbearing potential, pregnant women, the elderly, and those with common medical and psychiatric comorbidities, were considered. Selective serotonin reuptake inhibitors (SSRIs) are still the basic first-line medication. Early alternatives include duloxetine, buspirone, hydroxyzine, pregabalin, or bupropion, in that order. If response is inadequate, then the second recommendation is to try a different SSRI. Additional alternatives now include benzodiazepines, venlafaxine, kava, and agomelatine. If the response to the second SSRI is unsatisfactory, then the recommendation is to try a serotonin-norepinephrine reuptake inhibitor (SNRI). Other alternatives to SSRIs and SNRIs for treatment-resistant or treatment-intolerant patients include tricyclic antidepressants, second-generation antipsychotics, and valproate. This revision of the GAD algorithm responds to issues raised by new treatments under development (such as pregabalin) and organizes the evidence systematically for practical clinical application.

    To facilitate large-scale functional studies in Drosophila, the Drosophila Transgenic RNAi Project (TRiP) at Harvard Medical School (HMS) was established along with several goals: developing efficient vectors for RNAi that work in all tissues, generating a genome-scale collection of RNAi stocks with input from the community, distributing the lines as they are generated through existing stock centers, validating as many lines as possible using RT-qPCR and phenotypic analyses, and developing tools and web resources for identifying RNAi lines and retrieving existing information on their quality. With these goals in mind, here we describe in detail the various tools we developed and the status of the collection, which is currently composed of 11,491 lines and covering 71% of Drosophila genes. Data on the characterization of the lines either by RT-qPCR or phenotype is available on a dedicated website, the RNAi Stock Validation and Phenotypes Project (RSVP, http://www.flyrnai.org/RSVP.html), and stocks are available from three stock centers, the Bloomington Drosophila Stock Center (United States), National Institute of Genetics (Japan), and TsingHua Fly Center (China).

    AG Pegasi (AG Peg) is a symbiotic binary star composed of a red supergiant and a white dwarf. Between 1860 and 1870, AG Peg brightened from magnitude 9 to 6, before gradually dimming. In 2015, the star began another brightening phase. The outbursts are thought to be caused by accretion of material onto the white dwarf. Once there is enough hydrogen accreted, hydrogen shell-burning starts leading to the the star’s evolution into a A-supergiant with a high mass-loss rate (Kenyon et al. 1993). The Harvard Observing Project (HOP) collected photometric data in BVRI filters using Harvard’s 16-inch Clay Telescope in the Fall term of 2015 and again in the Fall term of 2016. HOP is designed to get undergraduate students interested in astronomy and observing, and to allow graduate students opportunities to interact with undergraduates and get more observing/teaching experience. This study monitors the luminosity of AG Peg to constrain the amplitude and duration of the latest outburst.

    Gerhardt, U

    1999-01-01

    This article argues that for Parsons and some of his colleagues at Harvard, the Second World War and the post-war period provided a context in which their work contributed to the transformation from totalitarianism to democracy in Central Europe (especially Germany) and Japan. The various agendas of Parsons' work are shown, supplemented by that of three of his colleagues with whom he collaborated (Gordon W. Allport, Carl J. Friedrich, Clyde Kluckhohn). The immediate effect of this work, for Parsons, however, meant frustration rather than fame, and his eventual reputation, I maintain, came unexpectedly with the third of his three attempts in the immediate post-war period to sum up what he believed were crucial insights that the Second World War had yielded concerning the ways in which sociology could contribute to the analytical understanding of democracy. The significance of this work is that it was both political and scientific. Because of the world situation of the 1940s, when the Holocaust in Germany was the nadir of civilization, Parsons believed that social science could contribute to the cause of making the world safe for future democracy. In the 1940s, this future depended on brave citizens, or such might have been Parsons' worldview. Targets envisaged for the 1950s, then, were community and citizenship in the newly democratic societies such as (West) Germany, the land that defeated Nazism. Copyright 1999 John Wiley & Sons, Inc.

    2011-03-01

    Full Text Available This essay examines two novels by Dominican American author Julia Alvarez, How the García Girls Lost Their Accents and In the Time of the Butterflies. By undertaking a transnational feminist reading practice, the author explicates the novels’ critique of the political constructions of the Latin American Third World as “deprived” and “depraved.” Alvarez’s work traces how these representations have been constitutive of a North American liberal feminist imaginary, limiting its conception of the forms of feminist agency available to women in the Americas as well as the liberal social rebellion and “development” of the woman of color in the United States. Ultimately, the two novels uncover the imperial history between the United States and the Dominican Republic that (neoliberal linkages otherwise obscure.

    Full Text Available A former model and fashion photographer turned war photographer, Lee Miller visited Romania twice, in 1938 and 1946 respectively. After her second visit she published her impressions and pictures, under the title of Roumania, in Vogue magazine. Besides the published material there are her manuscripts from The Lee Miller Achives at Farley Farm House, East Sussex, England, on which this paper is based. She crossed the border coming from Hungary in early February 1946. Heading for Sibiu her car, a Chevrolet Sedan, slipping on the ice-covered road, stopped on a snowbank far off in the ditch. While looking for help in the nearby village she and her companions left the car unguarded to discover it plundered of everything, wheels included.On a Sunday afternoon she had the privilege of being received by King Mihai I and Queen Mother Elena with whom she talked exstensively. She also took magnificent pictures with the Royal Family in the imposing Peleş Castle. At Sinaia, „the summer capital of Roumania” she had also the opportunity to portray Dinu Brătianu and Iuliu Maniu, the two elderly statesmen. Maniu was surrounded by friends and party members, among whom was young Corneliu Coposu, his private secretary.Moving to Bucharest, she met old friends such as Harri Brauner and his wife, Lena Constante, with whom she wandered through the country eight years ago. Lena and Elena Pătrășcanu, wife of Lucrețiu Pătrășcanu, Minister of Justice, have started a successful marionette theatre where Lee took nice pictures. Other were taken on the streets, with peasants, street vendors and their customers. Harri took her to a bistro where they met Maria Lătărețu, the celebrating folk singer whom Brauner recorded many times. They enjoyed her songs. Suffering from fibrositis, Lee Miller undertook a peculiar treatment in a gypsy village where the inhabitants were dancing bears trainers. She was massaged by a bear weighing about 300 pounds while Brauner took

  17. H-NST induces LEE expression and the formation of attaching and effacing lesions in enterohemorrhagic Escherichia coli.

    Full Text Available Enteropathogenic E. coli (EPEC and enterohemorrhagic E. coli are important causes of morbidity and mortality worldwide. These enteric pathogens contain a type III secretion system (T3SS responsible for the attaching and effacing (A/E lesion phenotype. The T3SS is encoded by the locus of enterocyte effacement (LEE pathogenicity island. The H-NS-mediated repression of LEE expression is counteracted by Ler, the major activator of virulence gene expression in A/E pathogens. A regulator present in EPEC, H-NST, positively affects expression of H-NS regulon members in E. coli K-12, although the effect of H-NST on LEE expression and virulence of A/E pathogens has yet-to-be determined.We examine the effect of H-NST on LEE expression and A/E lesion formation on intestinal epithelial cells. We find that H-NST positively affects the levels of LEE-encoded proteins independently of ler and induces A/E lesion formation. We demonstrate H-NST binding to regulatory regions of LEE1 and LEE3, the first report of DNA-binding by H-NST. We characterize H-NST mutants substituted at conserved residues including Ala16 and residues Arg60 and Arg63, which are part of a potential DNA-binding domain. The single mutants A16V, A16L, R60Q and the double mutant R60Q/R63Q exhibit a decreased effect on LEE expression and A/E lesion formation. DNA mobility shift assays reveal that these residues are important for H-NST to bind regulatory LEE DNA targets. H-NST positively affects Ler binding to LEE DNA in the presence of H-NS, and thereby potentially helps Ler displace H-NS bound to DNA.H-NST induces LEE expression and A/E lesion formation likely by counteracting H-NS-mediated repression. We demonstrate that H-NST binds to DNA and identify arginine residues that are functionally important for DNA-binding. Our study suggests that H-NST provides an additional means for A/E pathogens to alleviate repression of virulence gene expression by H-NS to promote virulence capabilities.

    [Purpose] Efficient management using exercise programs with various benefits should be provided by educational institutions for children in their growth phase. We analyzed the heart rates of children during ski simulator exercise and the Harvard step test to evaluate the cardiopulmonary endurance by calculating their post-exercise recovery rate. [Subjects and Methods] The subjects (n = 77) were categorized into a normal weight and an overweight/obesity group by body mass index. They performed each exercise for 3 minutes. The cardiorespiratory endurance was calculated using the Physical Efficiency Index formula. [Results] The ski simulator and Harvard step test showed that there was a significant difference in the heart rates of the 2 body mass index-based groups at each minute. The normal weight and the ski-simulator group had higher Physical Efficiency Index levels. [Conclusion] This study showed that a simulator exercise can produce a cumulative load even when performed at low intensity, and can be effectively utilized as exercise equipment since it resulted in higher Physical Efficiency Index levels than the Harvard step test. If schools can increase sport durability by stimulating students' interests, the ski simulator exercise can be used in programs designed to improve and strengthen students' physical fitness.

    In the late 1920s, the American obstetrician Joseph DeLee brought the motion-picture camera into the birth room. Following that era's trend of adapting industrial efficiency practices for medical environments, DeLee's films give spectacular and unexpected expression to the engineering concept of 'streamlining'. Accomplishing what more tangible obstetric streamlining practices had failed to, DeLee's cameras, and his post-production manipulation, shifted birth from messy and dangerous to rationalized, efficient, death-defying. This was film as an active and effective medical tool. Years later, the documentarian Pare Lorentz produced and wrote his own birth film, The Fight for Life (1940). The documentary subject of the film was DeLee himself, and the film was set in his hospitals, on the same maternity 'sets' that had once showcased film's remarkable streamlining capacity to give and keep life. Yet relatively little of DeLee was retained in the film's content, resulting in a showdown that, by way of contrast, further articulated DeLee's understanding of film's medical powers and, in so doing, hinted at a more dynamic moment in the history of medicine while speaking also to the process by which that understanding ceased to be historically legible.

    Lees are the wastes generated during the fermentation and aging processes of different industrial activities concerning alcoholic drinks such as wine, cider and beer. They must be conveniently treated to avoid uncontrolled dumping which causes environmental problems due to their high content of phenols, pesticides, heavy metals, and considerable concentrations of nitrogen, phosphate and potassium as well as high organic content. The companies involved must seek alternative environmental and economic physicochemical and biological treatments for their revalorization consisting in the recovery or transformation of the components of the lees into high value-added compounds. After describing the composition of lees and market of wine, beer and cider industries in Spain, this work aims to review the recent applications of wine, beer and cider lees reported in literature, with special attention to the use of lees as an endless sustainable source of nutrients and the production of yeast extract by autolysis or cell disruption. Lees and/or yeast extract can be used as nutritional supplements with potential exploitation in the biotechnological industry for the production of natural compounds such as xylitol, organic acids, and biosurfactants, among others.
