When Leonard D'Avolio (Figure 1) was working on his Ph.D. degree in biomedical informatics, he saw the power of machine learning in transforming multiple industries; health care, however, was not among them. "The reason that Amazon, Netflix, and Google have transformed their industries is because they have embedded learning throughout every aspect of what they do. If we could prove that is possible in health care too, I thought we would have the potential to have a huge impact," he says.

Full Text Available This paper describes how to teach Zen’s famous Ten Oxherding Pictures through Leonard Cohen’s song “Ballad of the Absent Mare.” It also explains how instructors can contextualize these pictures within the history of Buddhist visual culture and thereby frame Cohen’s adoption of them as a cowboy ballad motif. The essay begins by describing the metaphor of the ox. It then reviews three theories about the origin of the pictures, contextualizing them within the history of Buddhist visual culture. Finally, it provides a PowerPoint presentation that connects each of the Ten Oxherding Pictures to verses of Cohen’s song and offers comments for instructors’ use in class.

Constructing Failure: Leonard Hayflick, Biomedicine, and the Problems with Tissue Culture.

Science.gov (United States)

Park, Hyung Wook

2016-07-01

By examining the use of tissue culture in post-war American biomedicine, this paper investigates how scientists experience and manage failure. I study how Leonard Hayflick forged his new definition of failure and ways of managing it by refuting Alexis Carrel's definition of failure alongside his theory of the immortality of cultured cells. Unlike Carrel, Hayflick claimed that every vertebrate somatic cell should eventually die, unless it transformed into a tumour cell. This claim defined cell death, which had been a problem leading to a laboratory failure, as a normal phenomenon. On the other hand, permanent life, which had been considered a normal cellular characteristic, became a major factor causing scientific failure, since it implied malignant transformation that scientists hoped to control. Hayflick then asserted that his cell strains and method would partly enable scientists to manage this factor-especially that occurred through viral infection-alongside other causes of failure in routine tasks, including bacterial contamination. I argue that the growing biomedical enterprise fostered this work of Hayflick's, which had repercussions in both his career and the uses of cells in diverse investigations. His redefinition of failure in the age of biomedicine resulted in the broad dissemination of his cells, medium, and method as well as his long struggle with the National Institutes of Health (NIH), which caused his temporarily failed career.

The Wawel ensemble, including the Royal Castle, the Wawel Cathedral and other monuments, is perched on top of the Wawel hill immediately south of the Cracow Old Town, and is by far the most important collection of buildings in Poland. St. Leonard's Crypt is located under the Wawel Cathedral of St Stanislaus BM and St Wenceslaus M. It was built in the years 1090-1117 and was the western crypt of the pre-existing Romanesque Wawel Cathedral, so-called Hermanowska. Pope John Paul II said his first Mass on the altar of St. Leonard's Crypt on November 2, 1946, one day after his priestly ordination. The interior of the crypt is divided by eight columns into three naves with vaulted ceiling and ended with one apse. The tomb of Bishop Maurus, who died in 1118, is in the middle of the crypt under the floor; an inscription "+ MAVRVS EPC MCXVIII +" indicates the burial place and was made in 1938 after the completion of archaeological works which resulted in the discovery of this tomb. Moreover, the crypt hosts the tombs of six Polish kings and heroes: Michał Korybut Wiśniowiecki (King of the Polish-Lithuanian Commonwealth), Jan III Sobieski (King of the Polish-Lithuanian Commonwealth and Commander at the Battle of Vienna), Maria Kazimiera (Queen of the Polish-Lithuanian Commonwealth and consort to Jan III Sobieski), Józef Poniatowski (Prince of Poland and Marshal of France), Tadeusz Kościuszko (Polish general, revolutionary and a Brigadier General in the American Revolutionary War) and Władysław Sikorski (Prime Minister of the Polish Government in Exile and Commander-in-Chief of the Polish Armed Forces). The adjacent six crypts and corridors host the tombs of the other Polish kings, from Sigismund the Old to Augustus II the Strong, their families and several Polish heroes.

A Leonard-Sanders-Budiansky-Koiter-Type Nonlinear Shell Theory with a Hierarchy of Transverse-Shearing Deformations

Science.gov (United States)

Nemeth, Michael P.

2013-01-01

A detailed exposition on a refined nonlinear shell theory suitable for nonlinear buckling analyses of laminated-composite shell structures is presented. This shell theory includes the classical nonlinear shell theory attributed to Leonard, Sanders, Koiter, and Budiansky as an explicit proper subset. This approach is used in order to leverage the exisiting experience base and to make the theory attractive to industry. In addition, the formalism of general tensors is avoided in order to expose the details needed to fully understand and use the theory. The shell theory is based on "small" strains and "moderate" rotations, and no shell-thinness approximations are used. As a result, the strain-displacement relations are exact within the presumptions of "small" strains and "moderate" rotations. The effects of transverse-shearing deformations are included in the theory by using analyst-defined functions to describe the through-the-thickness distributions of transverse-shearing strains. Constitutive equations for laminated-composite shells are derived without using any shell-thinness approximations, and simplified forms and special cases are presented.

Cobalt Blues The Story of Leonard Grimmett, the Man Behind the First Cobalt-60 Unit in the United States

CERN Document Server

Almond, Peter R

2013-01-01

For the latter half of the 20th century, cobalt-60 units were the mainstay of radiation treatments for cancer. Cobalt Blues describes the development of the first cobalt-60 unit in the United States and the man behind it, Leonard Grimmett. Conceptually conceived before World War II, it only became possible because of the development of nuclear reactors during the war. Although Grimmett conceived of and published his ideas first, the Canadians built the first units because of the capability of their reactor to produce more suitable cobalt-60 sources. This book tells the story of how Grimmett and others came together at the time that the U S Atomic Energy Agency was pushing the use of radioactivity in medicine. Due to his sudden death, very little information about Grimmett was known until recently, when various documents have come to light, allowing the full story to be told.

A tale of three blind men on the proper subject matter of clinical science and practice: commentary on Plaud's behaviorism vs. Ilardi and Feldman's cognitive neuroscience.

Forsyth, J P; Kelly, M M

2001-09-01

Plaud (J Clin Psychol 57, 1089-1102, 1109-1111, 1119-1120) and Ilardi and Feldman (J Clin Psychol 57, 1067-1088, 1103-1107, 1113-1117, 1121-1124) argue for two very different approaches to clinical science and practice (i.e., behavior analysis and cognitive neuroscience, respectively). We comment on the assets and liabilities of both perspectives as presented and attempt to achieve some semblance of balance between the three protagonists embroiled in this current debate. The vision of clinical science we articulate is more ecumenical and evolutionary, rather than paradigmatic and revolutionary. As we see it, the problem clinical psychology faces is much larger than the authors let on; namely, how best to make clinical science meaningful and relevant to practitioners, consumers, the general public, and the behavioral health-care community. Clinical psychology's immediate internal problem is not pluralism with regard to subject matter, worldview, methodology, or school of thought, but pluralism in clinical psychologists' adherence to a scientific epistemology as the only legitimate form of clinical psychology. On this latter point, we still have a very long way to go. Copyright 2001 John Wiley & Sons, Inc.

Governor-General Leonard Wood’s neoliberal agenda of privatizing public assets stymied, 1921-1927

Full Text Available After a serious fiscal and financial crisis erupted in 1920 to 1921 (in the wake of the termination of World War I, the new American Governor General to the Philippines, U.S. Army Major General Leonard Wood, promised in his inaugural address to privatize the country’s government-owned and controlled corporations such as the Philippine National Bank and the Manila Railroad Company, among others. Wood’s neoliberal agenda in the Philippines was opposed by Filipino politicians in the executive and legislative departments from the start. This key policy disagreement climaxed in the resignation en masse of Governor Wood’s Filipino cabinet and the members of the executive-legislative Council of State in 1923. The particulars of the Cabinet Crisis of 1923 —the so-called Conley Affair— however, obscured from plain sight the true gravity of the broader conflict (i.e., Filipino opposition to Wood’s agenda.Moreover, the general perception that Governor Wood’s asset privatization program was successfully blocked by the Cabinet Crisis of 1923 is inaccurate. In truth, Wood was stymied by adverse international and national market conditions from 1921 to 1923. A further delay occurred from 1924 to 1926 when Governor Wood endeavored to get the Council of State and the Filipino Legislature’s Board of Control (an oversight committee on board his neoliberal agenda; he failed to get the support of the Filipino leaders in this regard. When Wood finally decided in 1926 to take unilateral steps, he was tied up by litigation (locally and in the United States arising from his actions until his death from an unsuccessful brain surgery in 1927.

Psyche=singularity: A comparison of Carl Jung's transpersonal psychology and Leonard Susskind's holographic string theory

Science.gov (United States)

Desmond, Timothy

In this dissertation I discern what Carl Jung calls the mandala image of the ultimate archetype of unity underlying and structuring cosmos and psyche by pointing out parallels between his transpersonal psychology and Stanford physicist Leonard Susskind's string theory. Despite his atheistic, materialistically reductionist interpretation of it, I demonstrate how Susskind's string theory of holographic information conservation at the event horizons of black holes, and the cosmic horizon of the universe, corroborates the following four topics about which Jung wrote: (1) his near-death experience of the cosmic horizon after a heart attack in 1944; ( 2) his equation relating psychic energy to mass, "Psyche=highest intensity in the smallest space" (1997, 162), which I translate into the equation, Psyche=Singularity; (3) his theory that the mandala, a circle or sphere with a central point, is the symbolic image of the ultimate archetype of unity through the union of opposites, which structures both cosmos and psyche, and which rises spontaneously from the collective unconscious to compensate a conscious mind torn by irreconcilable demands (1989, 334-335, 396-397); and (4) his theory of synchronicity. I argue that Susskind's inside-out black hole model of our Big Bang universe forms a geometrically perfect mandala: a central Singularity encompassed by a two-dimensional sphere which serves as a universal memory bank. Moreover, in precise fulfillment of Jung's theory, Susskind used that mandala to reconcile the notoriously incommensurable paradigms of general relativity and quantum mechanics, providing in the process a mathematically plausible explanation for Jung's near-death experience of his past, present, and future life simultaneously at the cosmic horizon. Finally, Susskind's theory also provides a plausible cosmological model to explain Jung's theory of synchronicity--meaningful coincidences may be tied together by strings at the cosmic horizon, from which they

Leonard Horner and an enthusiasm for Loess. [Leicester Studies in the History of Loess Research part I

Smalley, Ian; Kels, Holger

2018-04-01

Leonard Horner (1785-1864) made substantial contributions to the study of loess. He made field trips with J.J. Noeggerath and Charles Lyell and published useful material on the loess near Bonn. He was an unappreciated pioneer- he was the first person to direct attention to loess as a material. He pointed out that loess was intrinsically interesting. He studied the material transported by the Rhine, and the alluvial deposits in Egypt, looking for links to loess, and the problem of loess formation. He was born in Edinburgh in 1785 and directed the thoughts of young Charles Darwin towards science when he came to Edinburgh to study medicine. Circumstances placed him in Bonn in the critical years 1831-1833; in this time Charles Lyell married his eldest daughter Mary; and both Lyell and Horner encountered the loess. Lyell made it well known via vol.3 of the Principles of Geology, Horner became a loess enthusiast. In the summer of 1833 Horner & Lyell were in the crater of the Roderberg considering the more than 20 m of loess deposited there. His major paper was published in 1836 (reporting the Roderberg excursion) and he joined Lyell's list of loess investigators in the 5th edition of the Principles published in 1837. He was the last to join that select eleven: Bronn, Leonhard, Boue, Voltz, Steininger, Merian, Rozet, Hibbert, Noeggerath, von Meyer, Horner. Most of these were writing on the geology and landscapes of the Rhine valley, but Horner was drawing attention to the amazing nature of the loess itself, in particular the spectacular disaggregation on contact with water. He also published the first geological map of the Bonn region, including the Roderberg and the Siebengebirge, a region of loess and volcanoes.

The necessity of connection structures in neural models of variable binding.

Science.gov (United States)

van der Velde, Frank; de Kamps, Marc

2015-08-01

In his review of neural binding problems, Feldman (Cogn Neurodyn 7:1-11, 2013) addressed two types of models as solutions of (novel) variable binding. The one type uses labels such as phase synchrony of activation. The other ('connectivity based') type uses dedicated connections structures to achieve novel variable binding. Feldman argued that label (synchrony) based models are the only possible candidates to handle novel variable binding, whereas connectivity based models lack the flexibility required for that. We argue and illustrate that Feldman's analysis is incorrect. Contrary to his conclusion, connectivity based models are the only viable candidates for models of novel variable binding because they are the only type of models that can produce behavior. We will show that the label (synchrony) based models analyzed by Feldman are in fact examples of connectivity based models. Feldman's analysis that novel variable binding can be achieved without existing connection structures seems to result from analyzing the binding problem in a wrong frame of reference, in particular in an outside instead of the required inside frame of reference. Connectivity based models can be models of novel variable binding when they possess a connection structure that resembles a small-world network, as found in the brain. We will illustrate binding with this type of model with episode binding and the binding of words, including novel words, in sentence structures.

Bioassays for TSH Receptor Autoantibodies, from FRTL-5 Cells to TSH Receptor-LH/CG Receptor Chimeras: The Contribution of Leonard D. Kohn.

Giuliani, Cesidio; Saji, Motoyasu; Bucci, Ines; Napolitano, Giorgio

Since the discovery 60 years ago of the "long-acting thyroid stimulator" by Adams and Purves, great progress has been made in the detection of thyroid-stimulating hormone (TSH) receptor (TSHR) autoantibodies (TRAbs) in Graves' disease. Today, commercial assays are available that can detect TRAbs with high accuracy and provide diagnostic and prognostic evaluation of patients with Graves' disease. The present review focuses on the development of TRAbs bioassays, and particularly on the role that Leonard D. Kohn had in this. Indeed, 30 years ago, the Kohn group developed a bioassay based on the use of FRTL-5 cells that was characterized by high reproducibility, feasibility, and diagnostic accuracy. Using this FRTL-5 bioassay, Kohn and his colleagues were the first to develop monoclonal antibodies (moAbs) against the TSHR. Furthermore, they demonstrated the multifaceted functional nature of TRAbs in patients with Graves' disease, with the identification of stimulating and blocking TRAbs, and even antibodies that activated pathways other than cAMP. After the cloning of the TSHR, the Kohn laboratory constructed human TSHR-rat luteinizing hormone/chorionic gonadotropin receptor chimeras. This paved the way to a new bioassay based on the use of non-thyroid cells transfected with the Mc4 chimera. The new Mc4 bioassay is characterized by high diagnostic and prognostic accuracy, greater than for other assays. The availability of a commercial kit based on the Mc4 chimera is spreading the use of this assay worldwide, indicating its benefits for these patients with Graves' disease. This review also describes the main contributions made by other researchers in TSHR molecular biology and TRAbs assay, especially with the development of highly potent moAbs. A comparison of the diagnostic accuracies of the main TRAbs assays, as both immunoassays and bioassays, is also provided.

In (Cullen and Feldman 2006 SIAM J. Math. Anal. 37 137–95), Cullen and Feldman proved the existence of Lagrangian solutions for the semigeostrophic system in physical variables with initial potential vorticity in L p , p > 1. Here, we show that a subsequence of the Lagrangian solutions corresponding to a strongly convergent sequence of initial potential vorticities in L 1 converges strongly in L q , q < ∞, to a Lagrangian solution, in particular extending the existence result of Cullen and Feldman to the case p = 1. We also present a counterexample for Lagrangian solutions corresponding to a sequence of initial potential vorticities converging in BM. The analytical tools used include techniques from optimal transportation, Ambrosio's results on transport by BV vector fields and Orlicz spaces

Many beaches in Australia are under attack from shoreline erosion due rising sea levels and the action of waves. St Leonard's beach, a tourist town on the Victorian coastline, is of concern from this destructive erosion and the threat to the economic stability of the town. The major cause of erosion in this area is related to waves created from strong to gale force north to north-easterly winds. This in turn produces a northerly longshore current along with sediment suspension leading to a negative sediment budget. Ongoing and systematic monitoring of the shoreline movement is important to ensure the coast is understood and effectively managed now and into the future. Coastal land managers and agencies are required to find 'cost-effective' and 'fit-for-purpose' coastal monitoring methodologies which are affordable and efficient. This project forges a collaboration of stakeholders from academia, public sector land manager, local government and the private sector to compare four different methods of obtaining beach profiles. The four methods of obtaining beach profiles used for comparison are: 1. traditional survey method along transects using a total station theodolite, 2. traditional survey method along transects using a builder's grade laser level, 3. a small multi-rotor unmanned aerial vehicle (UAV) to produce a full 3D digital surface model of the study area, and 4. an experimental stationary device to produce a limited 3D model along a designated transect using terrestrial photogrammetric approach via a small GPS enabled camera. Assessment is made by comparing the method's precision, spatial coverage, expertise and equipment requirements/costs, preparation time, field acquisition time, number of people required in the field, post-acquisition processing time, and applicability for community use. Whilst is must be very clearly stated that all methods proved to be successful, the preliminary results of the "workflow and resourcing" assessment ranked the methods in

The Ultraviolet Albedo of Ganymede

McGrath, Melissa; Hendrix, A.

2013-10-01

A large set of ultraviolet images of Ganymede have been acquired with the Hubble Space Telescope over the last 15 years. These images have been used almost exclusively to study Ganymede’s stunning auroral emissions (Feldman et al. 2000; Eviatar et al. 2001; McGrath et al. 2004; Saur et al. 2011; McGrath et al. 2013), and even the most basic information about Ganymede’s UV albedo has yet to be gleaned from these data. We will present a first-cut analysis of both disk-averaged and spatially-resolved UV albedos of Ganymede, with focus on the spatially-resolved Lyman-alpha albedo, which has never been considered previously for this satellite. Ganymede's visibly bright regions are known to be rich in water ice, while the visibly dark regions seem to be more carbonaceous (Carlson et al., 1996). At Lyman-alpha, these two species should also have very different albedo values.

Landlady Kate Kennedy wanted to build her property in a conservation area three hours' drive south of San Francisco in a ranch-style house. Architect Jonathan Feldman added energy-efficient elements and a roof-integrated photovoltaic system to the project. Kennedy now produces more electricity than it can consume. [German] Hausherrin Kate Kennedy wollte ihr Anwesen in einem Naturschutzgebiet drei Autostunden suedlich von San Francisco unbedingt im Stil eines Ranch-Hauses bauen. Architekt Jonathan Feldman fuegte dem Projekt energieeffiziente Elemente und eine dachintegrierte Photovoltaikanlage hinzu. Nun produziert Kennedy mehr Solarstrom, als sie verbrauchen kann.

Determining vancomycin clearance in an overweight and obese population.

Science.gov (United States)

Leong, Julie V B; Boro, Maureen S; Winter, Michaele

2011-04-01

Two methods of calculating vancomycin clearance were compared to determine the best body weight measure to use when dosing vancomycin for overweight and obese patients. Hospitalized veterans weighing more than 120% of their ideal body weight (IBW) with serum vancomycin concentrations (SVCs) drawn between January 1, 2003, and June 30, 2005, were eligible for study inclusion. Exclusion criteria included weight of more than 300% the IBW, unstable renal function, dialysis, uncertain vancomycin dosing or sampling times, and distribution-phase sampling. Data from January 1 through December 31, 2003 (phase 1) determined the best-fit weight for vancomycin clearance for the Leonard and Boro method. The bias and precision of the modified Leonard and Boro method using the best-fit weight for vancomycin clearance were then compared with those of the Rushing and Ambrose method for predicting SVCs from January 1, 2004, through June 30, 2005 (phase 2). Forty-eight patients were included in phase 1, with 67 SVCs for analysis. During phase 1, adjusted body weight (ABW), using the Leonard and Boro method, was superior in predicting vancomycin clearance and the resultant SVCs. A total of 96 patients were included in phase 2 of the study, with 160 SVCs for analysis. The modified Leonard and Boro method was significantly more precise than the Rushing and Ambrose method in predicting vancomycin clearance. Use of ABW proved to be superior compared with total body weight when estimating vancomycin clearance in overweight and obese patients. While there was no difference in bias between methods, the modified Leonard and Boro method was significantly more precise than the Rushing and Ambrose method in predicting SVCs when dosing vancomycin for obese patients.

Toxoplasma gondii can infect all species of warm-blooded animals, including humans, and causes serious diseases in immunocompromized hosts. Live tachyzoites derived from serial passage in HeLa culture were used in the Sabin-Feldman dye test for detection of Toxoplasma gondii antibody in serum samples of 21 captive wild felids including one fishing cat (Prion nailurus viverrina), one leopard (Panthera pardus), two flat-headed cats (Prion nailurus planiceps), 6 tigers (Panthera tigris), two leopard cats (Felis bengalensis), two clouded leopards (Felis nebulosa), 3 pumas (Puma concolor), and 4 jungle cats (Felis chaus). Antibodies to Toxoplasma gondii were founded in 9 of 21 felids (42.8%). This study revealed that cell culture-derived tachyzoites can be used successfully as a source of live organisms in a gold standard Sabin-Feldman dye test, which is simpler, cheaper and less ethically sensitive than in vivo inoculation.

A Psychometric Evaluation of the Dutch Version of the Responses to Positive Affect Questionnaire

2010-12-01

Full Text Available In 698 respondents selected from the community, the authors examined the psychometric properties of the Dutch version of the Responses to Positive Affect questionnaire (RPA; Feldman, Joormann, & Johnson, 2008 which measures ruminative and dampening thoughts in response to positive affect. In a first sample ('n' = 170, exploratory factor analyses largely replicated the 3-factor model obtained by Feldman et al. (2008 with the following factors: Dampening, Self-focused positive rumination, and Emotion-focused positive rumination. The 3-factor model revealed in the first sample was confirmed using confirmatory factor analyses in a second independent sample of 528 respondents. All subscales showed adequate internal consistency and evidence of convergent and incremental validity with concurrent measures of depressive rumination, depressive symptoms, trait hypomania, and positive and negative affect. Results underscore the value of assessing responses to positive as well as negative affect in the study of mood disorders.

Search for Muon Neutrino Disappearance in the Booster Neutrino Beam of Fermilab; Busqueda de Desaparicion de Neutrinos del Muon en el Haz de Neutrinos del Booster de Fermilab

Energy Technology Data Exchange (ETDEWEB)

Mendez Mendez, Diana Patricia [Univ. Nacional Autonoma de Mexico (UNAM), Mexico City (Mexico)

2015-01-01

In this work we carried out the disappearance analysis of muon neutrinos produced in the Fermilab Booster Neutrino Beam, using the data released to the public by the collaborations of the MiniBooNE and SciBooNE experiments. The calculations were made with programs in C and C++, implementing the ROOT libraries. From the analysis, using both the classical Pearson method and the Feldman and Cousins frequentist corrections, we obtained the 90\\% C.L. limit for the oscillation parameters sin²2θ and Δm² in the region 0.1 ≤ Δm² ≤ 10 eV² using a two neutrino model. The result presented in this work is consistent with the official one, with small deviations ascribed to round-off errors in the format of the used data, as well as statistical fluctuations in the generation of fake experiments used in the Feldman and Cousins method. As the official one, our result is consistent with the null oscillation hypothesis. This work was carried out independently to the MiniBooNE and SciBooNE collaborations and its results are not official.

Alternative integral equations and perturbation expansions for self-coupled scalar fields

1985-01-01

It is shown that the theory of a self-coupled scalar field may be expressed in terms of a class of integral equations which include the Yang-Feldman equation as a particular case. Other integral equations in this class could be used to generate alternative perturbation expansions which contain a nonanalytic dependence upon the coupling constant and are less ultraviolet divergent than the conventional perturbation expansion.

As amnésias do contemporâneo

Directory of Open Access Journals (Sweden)

Bruschi, Michel Euclides

1997-01-01

Full Text Available Este artigo faz uma viagem pela mente de Leonard Shelby, personagem principal do filme Amnésia (2000. Esta aventura é feita juntamente com o auxílio das idéias sobre narrativa, self transacional e cultura de Jerome Bruner (1997a, 1997b e 2001. O objetivo é de no final da viagem conseguirmos fazer algumas reflexões sobre as amnésias que vivenciamos na contemporaneidade a partir do nosso olhar sobre Leonard. A primeira amnésia é a da fragmentação que é apontada como uma das causas do vazio de sentidos do nosso tempo. No entanto, a fragmentação não impossibilita a construção de sentidos, sendo apenas um novo dificultador desse processo. A segunda amnésia é a de que através das representações estamos acessando diretamente o mundo exterior, esquecendo de todo o processo que ocorre para construirmos uma representação

Full Text Available A helmintosporiose, causada pelo fungo Exserohilum turcicum, é uma das principais doenças do milho-pipoca cultivado no Brasil. Devido às características da cultura, como porte da planta, extensão da área de plantio e rentabilidade econômica, o emprego de resistência genética e controle químico têm sido as principais formas de controle da doença. O emprego de agrotóxicos na agricultura tem levado riscos à saúde humana e freqüentes danos ao meio ambiente. Assim, na busca de métodos alternativos para o controle da helmintosporiose foi avaliado o efeito fungitóxico dos extratos vegetais das plantas Achillea milefollium (mil-folhas, Cymbopogon citratus (capim-limão, Artemisia camphorata (cânfora e Rosmarinus officinalis (alecrim no crescimento micelial de E. turcicum, em dois meios de cultura (BDA - batata-dextrose-ágar; e LCH - lactose caseína hidrolisada.

Due to its characteristics, such as plant size, planting area extension and economic profitability, the use of genetic resistance and chemical control has constituted the main procedure against such disease. The use of pesticides in agriculture has resulted in risks to the human health and frequent damages to the environment. Thus, the fungitoxic effect of plant extracts of Achillea millefolium (yarrow, Cymbopogon citratus (lemon grass, Artemisia camphorata (camphor and Rosmarinus officinalis (rosemary on the mycelial growth of E. turcicum was evaluated by using two culture media (PDA - potato dextrose agar, and LCH - lactose-casein hydrolysate in order to set alternative methods for controlling helminthosporiose. Rosemary and camphor extracts led to higher mycelial growth inhibition in both culture media, whereas yarrow and lemon grass extracts stimulated mycelial growth in LCH medium.

This paper posits that our current understanding of Jihadist Terrorism as a monolithic sub-type of Political Terrorism is flawed and that as a result our governments counter this threat with inappropriately-adapted methods. The author argues: (A) There is a sub-type of Jihadist Terrorism that is more consistent with Walter’s ‘Military Terrorism’ or Feldman and Hinojosa’s ‘Guerrilla Warfare’ than within the typology of Political Terrorism; (B) The author-proposed sub-type of ‘War Terrorism’ s...

Control of tongue movements in speech: The Equilibrium point Hypothesis perspective

OpenAIRE

Perrier , Pascal; Loevenbruck , Hélène; Payan , Yohan

1996-01-01

In this paper , the application of the Equilibrium Point Hypothesis— originally proposed by Feldman for the control of limb movements— to speech control is analysed . In the first part , physiological data published in the literature which argue in favour of such control for the tongue are presented and the possible role of this motor process in a global control model of the tongue is explicated . In the second part , using the example of the acoustic variability associated with vowel reducti...

Hayflick, his limit, and cellular ageing.

Almost 40 years ago, Leonard Hayflick discovered that cultured normal human cells have limited capacity to divide, after which they become senescent -- a phenomenon now known as the 'Hayflick limit'. Hayflick's findings were strongly challenged at the time, and continue to be questioned in a few circles, but his achievements have enabled others to make considerable progress towards understanding and manipulating the molecular mechanisms of ageing.

Teasing apart the relations between age, birth cohort, and vocational interests.

Science.gov (United States)

Leuty, Melanie E; Hansen, Jo-Ida C

2014-04-01

Empirical evidence supports that aging is related to differences in work attitudes and motivation (Inceoglu, Segers, & Bartram, 2012; Kooij, de Lange, Jansen, Kanfer, & Kikkers, 2011; Ng & Feldman, 2008, 2010), but little research has explored the relations between age and vocational interests. Furthermore, recent studies of age and work attitudes suggest that generational experiences (i.e., birth year) may account for age differences in the workplace (Inceoglu et al., 2012; Ng & Feldman, 2008, 2010), which in turn suggests that researchers need to incorporate both age and birth cohort effects in their designs. Thus, this study was designed to explore the relations of age at the time of testing and birth year to vocational interests using a sample of adults (N = 1,792) collected over a period of 3 decades. As expected, age was not a significant predictor of most interests, but birth year also was not found to predict most interests, with the significant prediction of Realistic interests by both age and birth year being the exception. Gender, however, significantly predicted most areas of interests. Neither age nor gender moderated any relationships between birth year and interests. Results suggest that birth year and age were minimally related to interests as all effect sizes were small. Discussion of the results illustrates the need for further research on this issue and also offers considerations for attracting and retaining different generations of workers in light of the findings.

Underestimating advertising: innovation and unpriced entertainment

OpenAIRE

Leonard I. Nakamura

2005-01-01

Leonard Nakamura states that despite consumers’ lack of respect for advertising, it nonetheless plays a significant role in the economy. For one thing, it helps consumers find out about new products, and new products have been rising in economic importance. It also plays a role in subsidizing broadcast entertainment and news programs. Ultimately, Nakamura shows that although advertising contributes to consumer welfare, its contribution is missing from our measures of output.

Full Text Available The movie O romance do vaqueiro voador, by Manfredo Caldas, is built departing from the homonymous cordel by João Bosco Bezerra Bonfim – which, on its turn, was inspired by the documentary Brasília segundo Feldman, by Vladimir Carvalho – aiming to tell, denounce and remember the tragedy the building of the city was. This article aims to discuss some questions: why choose as a character a pot cowboy to wander in the places of the tragedy? Why use a cordel to give origin to another movie?

Transferring alien genes to wheat

International Nuclear Information System (INIS)

Knott, D.R.

1987-01-01

In broad terms an alien gene can be considered to be any gene transferred to wheat from a related species. As described above by Maan (section 7D) the genus Triticum contains a broad range of species, some of which cross readily with the cultivated tetraploid (T. Turgidum L.) or hexaploid (T. aestivum L.) wheats, and others only with great difficulty. In addition, wheat will also cross with species in a number of other genera including Agropyron, Elymus, Elytrigia (=Agropyron), Haynaldia, Hordeum, and Secale (Riley and Kimber, 1966; Knobloch, 1968; Feldman and Sears, 1981). In discussing the Triticum and Aegilops spp., the classification by Kimber and Sears, section SA-I, above, will be followed. For the Agropyron and related species the classification described by Dewey (1983) will be used. To avoid confusion, in referring to the literature the designations used by the authors will be given, followed by the new designation. The wild relatives of wheat are adapted to a broad range of environments and carry a large reservoir of useful genes (Zohary et al., 1969; Kerber and Dyck, 1973; Brezhnev, 1977; Feldman and Sears, 1981; Limin and Fowler, 1981; Sharma et aI., 1981; McGuire and Dvorak, 1981). Initially they were considered to be primarily sources of disease resistance, but more recently they have been recognized as potential sources of genes for high protein, cold tolerance, salt tolerance, drought tolerance, lodging resistance, early maturity, and even yield. Extensive screening of the wild relatives of wheat needs to be done before their useful genes can be fully utilized

Harriot, Digges, and the Ghost in Hamlet.

Science.gov (United States)

Usher, P. D.

1998-12-01

The cosmic allegorical interpretation of Hamlet (BAAS 28, 1305, 1996; 29, 1262, 1997; Giornale di Astronomia 24:3, 27, 1998) may be regarded as a Galilean postulatum with testable consequences. It associates leading characters in the play with cosmologists from the time of Ptolemy (Claudius) to Tycho Brahe (Rosencrantz and Guildenstern) and Thomas Digges (Hamlet). Lines 3.3.8-23 describe how the concepts of geocentricism and the sphere of fixed stars shared by the Ptolemaic and Tychonic models are imperiled by the Infinite Universe of Digges. Hitherto baffling lines 5.2.100-125 list in short order at least 16 attributes of Thomas Harriot, including his short bibliography (``soul of great article'') which may explain why he receives mention only in passing. The Ghost is Thomas Digges' father Leonard, who is a ``mole'' in the ``cellarage.'' That Leonard may have gone underground following restoration of his lands is supported by the range of years (1559-1574) of his alleged death, and conspicuous absence of a gravesite. Circumstances of his disappearance have remained mysterious (N&Q 2:X, 162, 1860; 6:X, 368, 515, 1884; 8:V, 186, 1894.) I suggest that, having been saved from execution and restored to gentility, he continued to work, writing in the tradition of his confrere's father Thomas Wyatt, Sr. who pioneered the English sonnet. The first Dowden series of sonnets reflects his love for his only child. The history of the perspective glass explains lines in Sonnets 14 and 103 (``my blunt invention'') and in the I.M.S. encomium wherein he did ``rowle back the heavens'' with a ``cleere and equall surface'' that is ``reflecting ages past.'' A portrait of Tycho helps date Sonnet 16 to between 1581 and 1585. Sonnets 18 and 87 would date to 1583 and 1595. Allusions to old age are not surprising.

On the scale similarity in large eddy simulation. A proposal of a new model

International Nuclear Information System (INIS)

Pasero, E.; Cannata, G.; Gallerano, F.

2004-01-01

Among the most common LES models present in literature there are the Eddy Viscosity-type models. In these models the subgrid scale (SGS) stress tensor is related to the resolved strain rate tensor through a scalar eddy viscosity coefficient. These models are affected by three fundamental drawbacks: they are purely dissipative, i.e. they cannot account for back scatter; they assume that the principal axes of the resolved strain rate tensor and SGS stress tensor are aligned; and that a local balance exists between the SGS turbulent kinetic energy production and its dissipation. Scale similarity models (SSM) were created to overcome the drawbacks of eddy viscosity-type models. The SSM models, such as that of Bardina et al. and that of Liu et al., assume that scales adjacent in wave number space present similar hydrodynamic features. This similarity makes it possible to effectively relate the unresolved scales, represented by the modified Cross tensor and the modified Reynolds tensor, to the smallest resolved scales represented by the modified Leonard tensor] or by a term obtained through multiple filtering operations at different scales. The models of Bardina et al. and Liu et al. are affected, however, by a fundamental drawback: they are not dissipative enough, i.e they are not able to ensure a sufficient energy drain from the resolved scales of motion to the unresolved ones. In this paper it is shown that such a drawback is due to the fact that such models do not take into account the smallest unresolved scales where the most dissipation of turbulent SGS energy takes place. A new scale similarity LES model that is able to grant an adequate drain of energy from the resolved scales to the unresolved ones is presented. The SGS stress tensor is aligned with the modified Leonard tensor. The coefficient of proportionality is expressed in terms of the trace of the modified Leonard tensor and in terms of the SGS kinetic energy (computed by solving its balance equation). The

Following in a psychological and musicological tradition beginning with Leonard Meyer, and continuing through David Huron, we present a functional, cognitive account of the phenomenon of expectation in music, grounded in computational, probabilistic modeling. We summarize a range of evidence for this approach, from psychology, neuroscience, musicology, linguistics, and creativity studies, and argue that simulating expectation is an important part of understanding a broad range of human faculties, in music and beyond.

Noncommutative time in quantum field theory

International Nuclear Information System (INIS)

Salminen, Tapio; Tureanu, Anca

2011-01-01

We analyze, starting from first principles, the quantization of field theories, in order to find out to which problems a noncommutative time would possibly lead. We examine the problem in the interaction picture (Tomonaga-Schwinger equation), the Heisenberg picture (Yang-Feldman-Kaellen equation), and the path integral approach. They all indicate inconsistency when time is taken as a noncommutative coordinate. The causality issue appears as the key aspect, while the unitarity problem is subsidiary. These results are consistent with string theory, which does not admit a time-space noncommutative quantum field theory as its low-energy limit, with the exception of lightlike noncommutativity.

Budget projections - 1991 through 1996 for research in high energy physics

International Nuclear Information System (INIS)

1991-05-01

This research program in high energy physics is carried out under the general supervision of a committee which is composed of G.W. Brandenburg, G.J. Feldman, M.E. Franklin, R.J. Glauber, K. Kinoshita, F.M. Pipkin, K. Strauch, R. Wilson, and H. Yamamoto. Professor G.J. Feldman currently serves as chair of this committee. Dr. Brandenburg is the Director of the High Energy Physics Laboratory and administers the DOE high energy physics contract. In the fall of 1991 S. Mishra will join this committee. Harvard is planning to make one or two additional senior faculty appointments in experimental high energy physics over the next two years. The principal goals of the work described here are to carry out forefront programs in high energy physics research and to provide first rate educational opportunities for students. The experimental program supported through HEPL is carried out at the major accelerator centers in the world and addresses some of the most important questions in high energy physics. Harvard's educational efforts are concentrated in graduate education, where they are currently supporting thirteen research students. In addition, undergraduate students work in projects at HEPL during the academic year and over summers. These budget projections cover all of the Harvard based high energy physics experimental activities. The open-quotes umbrellaclose quotes nature of this contract greatly simplifies support of essential central technical and computer services and helps the group to take advantage of new physics opportunities and to respond to unexpected needs. The funding for the operation of the HEPL facility is shared proportionally by the experimental groups. Harvard financially supports this high energy physics research program in many ways

Quantized fields in interaction with external fields. Pt. 1

We consider a massive, charged, scalar quantized field interacting with an external classical field. Guided by renormalized perturbation theory we show that whenever the integral equations defining the Feynman or retarded or advanced interaction kernel possess non perturbative solutions, there exists an S-operator which satisfies, up to a phase, the axioms of Bogoliubov, and is given for small external fields by a power series which converges on coherent states. Furthermore this construction is shown to be equivalent to the one based on the Yang-Kaellen-Feldman equation. This is a consequence of the relations between chronological and retarded Green's functions which are described in detail. (orig.) [de

Here the authors present the SU(5) symmetry scheme by chosing the truth quark (t) as the fifth quark. To classify baryons and mesons, including the upsilon mesons and the associated hadrons, the Gel'fand and Tsetlin technique is exploited. This proves to be an elegant technique in this analysis. Also some relations are found between the masses of the truthful (3 + /2) baryons and the (3 + /2) non-truthful baryons by applying the Feldman and Matthews parallelogram rule to the different parallelograms formed by different baryons in the weight diagram. The results obtained by applying this rule are almost consistent with the corresponding results obtained from the mass spectrum of 3 + /2 baryons. (author)

Solar variability and climate change: An historical perspective

Science.gov (United States)

Feldman, Theodore S.

There is nothing new about the debate over the Sun's influence on terrestrial climate.As early as the late 18th century, widespread concern for the deterioration of the Earth's climate led to speculation about the Sun's role in climate change [Feldman, 1993; Fleming, 1990]. Drawing analogies with variations in the brightness of stars, the British astronomer William Herschel suggested that greater sunspot activity would result in warmer terrestrial climates. Herschel supported his hypothesis by referring to price series for wheat published in Adam Smiths Wealth of Nations [Hufbauer, 1991]. Later, the eminent American physicist Joseph Henry demonstrated by thermopile measurements that, contrary to Herschel's assumption, sunspots were cooler than the unblemished portions of the solar disk.

Suprathermal protons in the interplanetary solar wind

Science.gov (United States)

Goodrich, C. C.; Lazarus, A. J.

1976-01-01

Using the Mariner 5 solar wind plasma and magnetic field data, we present observations of field-aligned suprathermal proton velocity distributions having pronounced high-energy shoulders. These observations, similar to the interpenetrating stream observations of Feldman et al. (1974), are clear evidence that such proton distributions are interplanetary rather than bow shock associated phenomena. Large Alfven speed is found to be a requirement for the occurrence of suprathermal proton distribution; further, we find the proportion of particles in the shoulder to be limited by the magnitude of the Alfven speed. It is suggested that this last result could indicate that the proton thermal anisotropy is limited at times by wave-particle interactions

The Rutherford back scattering spectrometry (RBS)/channelling spectra of KTP crystals and the dark-mode spectrum have been measured. According to the multiple scattering formulae of Feldman and Rodgers, the damage profiles of z-cut KTP crystals have been calculated and extracted. The relations between the damage ratio, fluence and the ion-implanted depth have been established.

A dynamic global-coefficient mixed subgrid-scale model for large-eddy simulation of turbulent flows

International Nuclear Information System (INIS)

Singh, Satbir; You, Donghyun

2013-01-01

Highlights: ► A new SGS model is developed for LES of turbulent flows in complex geometries. ► A dynamic global-coefficient SGS model is coupled with a scale-similarity model. ► Overcome some of difficulties associated with eddy-viscosity closures. ► Does not require averaging or clipping of the model coefficient for stabilization. ► The predictive capability is demonstrated in a number of turbulent flow simulations. -- Abstract: A dynamic global-coefficient mixed subgrid-scale eddy-viscosity model for large-eddy simulation of turbulent flows in complex geometries is developed. In the present model, the subgrid-scale stress is decomposed into the modified Leonard stress, cross stress, and subgrid-scale Reynolds stress. The modified Leonard stress is explicitly computed assuming a scale similarity, while the cross stress and the subgrid-scale Reynolds stress are modeled using the global-coefficient eddy-viscosity model. The model coefficient is determined by a dynamic procedure based on the global-equilibrium between the subgrid-scale dissipation and the viscous dissipation. The new model relieves some of the difficulties associated with an eddy-viscosity closure, such as the nonalignment of the principal axes of the subgrid-scale stress tensor and the strain rate tensor and the anisotropy of turbulent flow fields, while, like other dynamic global-coefficient models, it does not require averaging or clipping of the model coefficient for numerical stabilization. The combination of the global-coefficient eddy-viscosity model and a scale-similarity model is demonstrated to produce improved predictions in a number of turbulent flow simulations

Rational decisions

It is widely held that Bayesian decision theory is the final word on how a rational person should make decisions. However, Leonard Savage--the inventor of Bayesian decision theory--argued that it would be ridiculous to use his theory outside the kind of small world in which it is always possible to ""look before you leap.""

The present study was conducted to investigate the prevalence of Toxoplasma gondii specific antibodies in domestic (Columba livia domestica) and wild (Columba livia livia) pigeons between October 2003-June 2004. Blood samples were collected from 216 pigeons, consisting of 105 (55 female, 50 male) domestic pigeons and 111 (53 female, 58 male) wild pigeons. The sera were tested for T. gondii antibodies using the Sabin Feldman Dye Test (SFDT). One of the 105 (0.95%) domestic pigeon and one of the 111 (0.90%) wild pigeon were found to be seropositive for T. gondii antibodies at the titer of 1:16. This is the first serological study on toxoplasmosis in the domestic and wild pigeon in the Niğde region of Turkey.

Relative Importance for Linear Regression in R: The Package relaimpo

Ulrike Gromping

2006-09-01

Full Text Available Relative importance is a topic that has seen a lot of interest in recent years, particularly in applied work. The R package relaimpo implements six different metrics for assessing relative importance of regressors in the linear model, two of which are recommended - averaging over orderings of regressors and a newly proposed metric (Feldman 2005 called pmvd. Apart from delivering the metrics themselves, relaimpo also provides (exploratory bootstrap confidence intervals. This paper offers a brief tutorial introduction to the package. The methods and relaimpo’s functionality are illustrated using the data set swiss that is generally available in R. The paper targets readers who have a basic understanding of multiple linear regression. For the background of more advanced aspects, references are provided.

Recent tests of the equilibrium-point hypothesis (lambda model).

1998-07-01

The lambda model of the equilibrium-point hypothesis (Feldman & Levin, 1995) is an approach to motor control which, like physics, is based on a logical system coordinating empirical data. The model has gone through an interesting period. On one hand, several nontrivial predictions of the model have been successfully verified in recent studies. In addition, the explanatory and predictive capacity of the model has been enhanced by its extension to multimuscle and multijoint systems. On the other hand, claims have recently appeared suggesting that the model should be abandoned. The present paper focuses on these claims and concludes that they are unfounded. Much of the experimental data that have been used to reject the model are actually consistent with it.

The Socratic method in teaching medical ethics: potentials and limitations.

Science.gov (United States)

Birnbacher, D

1999-01-01

The Socratic method has a long history in teaching philosophy and mathematics, marked by such names as Karl Weierstrass, Leonard Nelson and Gustav Heckmann. Its basic idea is to encourage the participants of a learning group (of pupils, students, or practitioners) to work on a conceptual, ethical or psychological problem by their own collective intellectual effort, without a textual basis and without substantial help from the teacher whose part it is mainly to enforce the rigid procedural rules designed to ensure a fruitful, diversified, open and consensus-oriented thought process. Several features of the Socratic procedure, especially in the canonical form given to it by Heckmann, are highly attractive for the teaching of medical ethics in small groups: the strategy of starting from relevant singular individual experiences, interpreting and cautiously generalizing them in a process of inter-subjective confrontation and confirmation, the duty of non-directivity on the part of the teacher in regard to the contents of the discussion, the necessity, on the part of the participants, to make explicit both their own thinking and the way they understand the thought of others, the strict separation of content level and meta level discussion and, not least, the wise use made of the emotional and motivational resources developing in the group process. Experience shows, however, that the canonical form of the Socratic group suffers from a number of drawbacks which may be overcome by loosening the rigidity of some of the rules. These concern mainly the injunction against substantial interventions on the part of the teacher and the insistence on consensus formation rooted in Leonard Nelson's Neo-Kantian Apriorism.

Sixteenth Century Astronomical Telescopy

Science.gov (United States)

Usher, P. D.

2001-12-01

Ophelia in Shakespeare's Hamlet is named for the ``moist star" which in mythology is the partner of Hamlet's royal Sun. Together the couple seem destined to rule on earth just as their celestial counterparts rule the heavens, but the tragedy is that they are afflicted, just as the Sun and Moon are blemished. In 1.3 Laertes lectures Ophelia on love and chastity, describing first Cytherean phases (crescent to gibbous) and then Lunar craters. Spots mar the Sun (1.1, 3.1). Also reported are Jupiter's Red Spot (3.4) and the resolution of the Milky Way into stars (2.2). These interpretations are well-founded and support the cosmic allegory. Observations must have been made with optical aid, probably the perspective glass of Leonard Digges, father of Thomas Digges. Notably absent from Hamlet is mention of the Galilean moons, owing perhaps to the narrow field-of-view of the telescope. That discovery is later celebrated in Cymbeline, published soon after Galileo's Siderius Nuncius in 1610. In 5.4 of Cymbeline the four ghosts dance ``in imitation of planetary motions" and at Jupiter's behest place a book on the chest of Posthumus Leonatus. His name identifies the Digges father and son as the source of data in Hamlet since Jupiter's moons were discovered after the deaths of Leonard (``leon+hart") and Thomas (the ``lion's whelp"). Lines in 5.4 urge us not to read more into the book than is contained between its covers; this is understandable because Hamlet had already reported the other data in support of heliocentricism and the cosmic model discussed and depicted by Thomas Digges in 1576. I conclude therefore that astronomical telescopy began in England before the last quarter of the sixteenth century.

Hawk and Handsaw

Science.gov (United States)

Usher, Peter D.

2008-05-01

In Shakespeare's Hamlet, Prince Hamlet states, "I am but mad north-north-west. When the wind is southerly, I know a hawk from a handsaw." This celebrated yet perennially baffling passage is readily understood in the context of the cosmic allegorical interpretation of the play (BAAS 28, 1305, 1996; Hamlet's Universe, 2006). The first direction points from Tycho Brahe's observatory on Hven to the fictional home of the geocentric Pyolemaic worldview at Elsinore, and the second from Hven to the home of Copernican heliocentricism at Wittenberg. The directions correspond to the two influences on Tycho's geo-heliocentric World model. Anyone at Elsinore who advocates the new organon of the New Philosophy is "mad," whereas sanity prevails at Wittenberg. "Hawk" refers to a bird of prey, the leonard, and to Leonard Digges, inventor of the world's first two-element telescope. "Handsaw" refers to the artistic tool necessary to sever the hands depicted in de Gheyn's two quasi-mirror-imaged portraits of Tycho at age 40, which show hands affixed to the wrong arms. Elsewhere in Hamlet, Shakespeare substantiates the New Astronomy through descriptions of planets and stars that could only have been determined telescopically. Therefore, the passage in question contrasts two modes of observing in the early modern era, viz. visual and telescopic. Shakespeare completed writing Hamlet in about 1601 and the Second Quarto appeared in 1604, so the first substantial account of astronomical telescopy is now over 400 years old. In addition, 432 years ago Thomas Digges published the first account of the New Astronomy in a popular almanac. These two means of presentation may seem odd by present standards, but contemporary culture was intolerant of 'natural magic,' and furthermore, it was prudent to minmize the risk of domestic persecution and threats from Continental armies and the European and Spanish Inquisitions.

In the popular imagination, the iconic American theoretical physicist is Richard Feynman, in all his safe-cracking, bongo-thumping, woman-chasing glory. I suspect that many physicists, if asked to name a living colleague who best captures the spirit of Feynman, would give the same answer as me: Leonard Susskind. As far as I know, Susskind does not crack safes, thump bongos, or chase women, yet he shares Feynman's brash cockiness (which in Susskind's case is leavened by occasional redeeming flashes of self-deprecation) and Feynman's gift for spinning fascinating anecdotes. If you are having a group of physicists over for dinner and want to be sure to have a good time, invite Susskind.

In this follow-up to the bestselling The Theoretical Minimum, physicist Leonard Susskind and data engineer Art Friedman offer a first course in the theory and associated mathematics of the strange world of quantum mechanics. Quantum Mechanics presents Susskind and Friedman’s crystal-clear explanations of the principles of quantum states, uncertainty and time dependence, entanglement, and particle and wave states, among other topics. An accessible but rigorous introduction to a famously difficult topic, Quantum Mechanics provides a tool kit for amateur scientists to learn physics at their own pace.

Study on the Pollution-heaven Hypothesis Focusing on Pollution-Intensive Industries

The purpose of this study is to test pollution-heaven hypothesis on the Korean pollution-intensive industries, that is, textile and clothing, petrochemical and primary metal industry. The empirical study examines that foreign direct investment(FDI) of Korean pollution-intensive industries regresses on couple of exogenous variables and the environmental regulation on FDI. As the environmental regulation is not directly observed, it uses C0{sub 2} emissions as the pollutant. The results of the study show that the environmental regulation in a host country is an insignificant determinant of FDI for the Korean polluting industries. That is, they do not support Leonard (1988), Xing and Kolstad (2000) that the hypothesis is a significant for heavily polluting industries. (author). 34 refs., 10 tabs.

Spherical harmonics and energy polynomial solution of the Boltzmann equation for neutrons, 1

International Nuclear Information System (INIS)

Toledo, P.S. de

1974-01-01

The approximate solution of the source-free energy-dependent Boltzmann transport equation for neutrons in plane geometry and isotropic scattering case was given by Leonard and Ferziger using a truncated development in a series of energy-polynomials for the energy dependent neutron flux and solving exactly for the angular dependence. The presence in the general solution of eigenfunctions belonging to a continuous spectrum gives rise to difficult analytical problems in the application of their method even to simple problems. To avoid such difficulties, the angular dependence is treated by a spherical harmonics method and a general solution of the energy-dependent transport equation in plane geometry and isotropic scattering is obtained, in spite of the appearance of matrices as argument of the angular polynomials [pt

The evolution of vortical structure in an impulsively started round jet has been studied numerically by means of a three-dimensional vortex blob method. The viscous diffusion of vorticity is approximated by a core spreading model originally proposed by Leonard (1980). The jet is forced by axisymmetric, helical and multiple disturbances. The multiple disturbances are combinations of two helical disturbances of the same mode rotating in the opposite directions. The multiple disturbances are found to enhance both the generation of small-scale structures and the growth rate of the jet. The small-scale structures have highly organized spatial distributions. The core spreading method is effective in aquiring the core overlapping in regions of high extensional rate of strain. 21 refs., 12 figs.

"Cosmomorphistic geometry" in the unconscious geometry of Johannes Kepler

Adam, Adolf

Some mathematical aspects of the Music theory by Johannes Kepler are discussed, paying a special attention to the book "De harmonice mundi". Other scientists interested in Music theory are mentioned throughout the paper: The Pythagorean school, Klaudios Ptolemaios, Leonard Euler, Gottfried Wilhelm Leibniz, Christian von Goldbach, Hermann Ludwig Ferdinand von Helmholz, Karl Friedrich Gauss. The relation with the ancient chinese schools of cosmography has been discussed: From the the Pythagorean to the ancient Chinese schools of cosmography we find arithmo-geometrical applications of numbers which are emblematic, hold meaning or represent the essence of things, the author writes. It was Johannes Kepler who taught us this "transconstructive method" of forming classical and ancient begginings of structuralistic thinking into a system from which deductions can readily be made.

Instrumental learning and relearning in individuals with psychopathy and in patients with lesions involving the amygdala or orbitofrontal cortex.

Previous work has shown that individuals with psychopathy are impaired on some forms of associative learning, particularly stimulus-reinforcement learning (Blair et al., 2004; Newman & Kosson, 1986). Animal work suggests that the acquisition of stimulus-reinforcement associations requires the amygdala (Baxter & Murray, 2002). Individuals with psychopathy also show impoverished reversal learning (Mitchell, Colledge, Leonard, & Blair, 2002). Reversal learning is supported by the ventrolateral and orbitofrontal cortex (Rolls, 2004). In this paper we present experiments investigating stimulus-reinforcement learning and relearning in patients with lesions of the orbitofrontal cortex or amygdala, and individuals with developmental psychopathy without known trauma. The results are interpreted with reference to current neurocognitive models of stimulus-reinforcement learning, relearning, and developmental psychopathy.

Pulsed neutron determination of anisotropic diffusion constants in multi-layered slabs

International Nuclear Information System (INIS)

Sri Ram, K.

1978-01-01

Anisotropic neutron diffusion parameters for graphite and plexiglas slab assemblies were calculated using one-dimensional discrete ordinates code ANISN, and also Case's eigenfunction expansion technique as suggested by Leonard. These calculated values were checked with the pulsed neutron experimental results as well as simple diffusion theory calculations of Spinrad. Relatively little experimental work has been done with heterogeneous assemblies which do not contain voids. The present comparison shows that the experimental results agree well with transport theory calculations. It appears from the results and inter-comparison of this work in simple geometries, that the pulsed neutron method can yield accurate experimental anisotropic diffusion constants, and can therefore be applied to more complicated geometries which may be difficult to calculate.

Grain-boundary free energy in an assembly of elastic disks.

Science.gov (United States)

Lusk, Mark T; Beale, Paul D

2004-02-01

Grain-boundary free energy is estimated as a function of misoriention for symmetric tilt boundaries in an assembly of nearly hard disks. Fluctuating cell theory is used to accomplish this since the most common techniques for calculating interfacial free energy cannot be applied to such assemblies. The results are analogous to those obtained using a Leonard-Jones potential, but in this case the interfacial energy is dominated by an entropic contribution. Disk assemblies colorized with free and specific volume elucidate differences between these two characteristics of boundary structure. Profiles are also provided of the Helmholtz and Gibbs free energies as a function of distance from the grain boundaries. Low angle grain boundaries are shown to follow the classical relationship between dislocation orientation/spacing and misorientation angle.

Monte Carlo molecular simulation of phase-coexistence for oil production and processing

KAUST Repository

Li, Jun

2011-01-01

The Gibbs-NVT ensemble Monte Carlo method is used to simulate the liquid-vapor coexistence diagram and the simulation results of methane agree well with the experimental data in a wide range of temperatures. For systems with two components, the Gibbs-NPT ensemble Monte Carlo method is employed in the simulation while the mole fraction of each component in each phase is modeled as a Leonard-Jones fluid. As the results of Monte Carlo simulations usually contain huge statistical error, the blocking method is used to estimate the variance of the simulation results. Additionally, in order to improve the simulation efficiency, the step sizes of different trial moves is adjusted automatically so that their acceptance probabilities can approach to the preset values.

Review of thorium-U233 cycle thermal reactor benchmark studies (AWBA Development Program)

A survey is made of existing integral experiments for U233 systems and thorium-uranium based fuel systems. The aim is to understand to what extent they give a consistent test of ENDF/B-IV nuclear data. A principal result is that ENDF/B-IV leads to an underprediction of neutron leakage. Results from testing alternate thorium data sets are presented. For one evaluation due to Leonard, the results depict a possible growing discrepancy between measured integral parameters such as rho 02 and I 232 and the differential data, which underpredicts these parameters. Sensitivities to other nuclear data components, notably the fission neutron spectrum, were determined. A new harder U233 spectrum significantly reduces a bias trend in K/sub eff/ vs leakage

Supporting student skill development in undergraduate research experiences through the development of a self-reflection guide

Science.gov (United States)

Hubenthal, M.; Brudzinski, M.

2016-12-01

There has been an increased emphasis on documenting the benefits of participating in undergraduate research opportunities (URO) and developing an understanding of the factors that influence these benefits. While tools to effectively measure the behavior, attitude, skills, interest, and/or knowledge (BASIK) that result from UROs have matured, little focus has been placed on developing practical tools and strategies to support students and mentors as they work to develop the BASIK being measured. Viewed through the lens of constructivism, a URO can be examined as a cognitive apprenticeship (CA) where learning occurs through several key methods: modeling, coaching, scaffolding, articulation, reflection, and exploration. In a study of UROs as CA, Feldman et al., (2013) found reflection to be one of the least commonly initiated methods employed by interns and mentors, and concluded, "there is need for professors to be more proactive in helping their students gain intellectual proficiency". This work, in its pilot stages, seeks to address this gap through the development of an intern self-reflection guide and implementation plan to further increase students' skill development. The guide is being developed based on IRIS's existing self-reflection tool. However, it has recently been revised to bring its constructs and items into better alignment with those of the Undergraduate Research Student Self-Assessment (URSSA) tool. The URSSA was selected because it is designed to measure skills and has recently undergone a validation study. In addition, it serves as the basis for the development of a new tool, the NSF Biology REU CORE. The revised self-reflection guide and protocol were piloted this summer in IRIS Summer REU program. The alignment between the constructs of the URSSA and the self-reflection guide will be presented along with findings from the 2016 program evaluation. Future development of the intervention will include a validation of the items on the self

1998-01-01

The lambda version of the equilibrium-point (EP) hypothesis as developed by Feldman and colleagues has been widely used and cited with insufficient critical understanding. This article offers a small antidote to that lack. First, the hypothesis implicitly, unrealistically assumes identical transformations of lambda into muscle tension for antagonist muscles. Without that assumption, its definitions of command variables R, C, and lambda are incompatible and an EP is not defined exclusively by R nor is it unaffected by C. Second, the model assumes unrealistic and unphysiological parameters for the damping properties of the muscles and reflexes. Finally, the theory lacks rules for two of its three command variables. A theory of movement should offer insight into why we make movements the way we do and why we activate muscles in particular patterns. The EP hypothesis offers no unique ideas that are helpful in addressing either of these questions.

We study broken symmetry states at integer Landau-level fillings in multivalley quantum Hall systems whose low-energy dispersions are anisotropic. When the Fermi surface of individual pockets lacks twofold rotational symmetry, like in bismuth (111) [Feldman et al. , Observation of a Nematic Quantum Hall Liquid on the Surface of Bismuth, Science 354, 316 (2016), 10.1126/science.aag1715] and in Sn1 -xPbxSe (001) [Dziawa et al., Topological Crystalline Insulator States in Pb1 -xSnxSe , Nat. Mater. 11, 1023 (2012), 10.1038/nmat3449] surfaces, interactions tend to drive the formation of quantum Hall ferroelectric states. We demonstrate that the dipole moment in these states has an intimate relation to the Fermi surface geometry of the parent metal. In quantum Hall nematic states, like those arising in AlAs quantum wells, we demonstrate the existence of unusually robust Skyrmion quasiparticles.

Dynamical behaviors determined by the Lyapunov function in competitive Lotka-Volterra systems

Science.gov (United States)

Tang, Ying; Yuan, Ruoshi; Ma, Yian

2013-01-01

Dynamical behaviors of the competitive Lotka-Volterra system even for 3 species are not fully understood. In this paper, we study this problem from the perspective of the Lyapunov function. We construct explicitly the Lyapunov function using three examples of the competitive Lotka-Volterra system for the whole state space: (1) the general 2-species case, (2) a 3-species model, and (3) the model of May-Leonard. The basins of attraction for these examples are demonstrated, including cases with bistability and cyclical behavior. The first two examples are the generalized gradient system, where the energy dissipation may not follow the gradient of the Lyapunov function. In addition, under a new type of stochastic interpretation, the Lyapunov function also leads to the Boltzmann-Gibbs distribution on the final steady state when multiplicative noise is added.

Photon propagator and pair production in stationary electric field

International Nuclear Information System (INIS)

Makhlin, A.N.; Olejnik, V.P.

1978-01-01

Effects related to pair production by an external field are discussed. It is shown that vacuum instability against pair production leads to an essential difference between the propagator and Feynman Green's function. Analysis of Yang-Feldman equations and of boundary conditions imposed upon the Green's function shows that using Feynman Green's function as a propagator contradicts the causality principle. The physical causality principle is satisfied by Heisenberg Green's function for which usual Schwinger-Dyson equations cannot be formulated. Heisenberg and Feynman Green's functions coincide for the case of stable vacuum state. All calculations are carried out using the technique of the so-called generalized Green's functions in terms of which the propagators are written. The polarization operator in the electric field is calculated in the one-loop approximation. Its' general structure is found. The photon propagator is obtained. Self oscillations of the photon vacuum are determined. It is shown that new modes correspond to collective excitations of the type ''photon+electron-positron pairs''

Fermionic functional integrals and the renormalization group

CERN Document Server

Feldman, Joel; Trubowitz, Eugene

2002-01-01

This book, written by well-known experts in the field, offers a concise summary of one of the latest and most significant developments in the theoretical analysis of quantum field theory. The renormalization group is the name given to a technique for analyzing the qualitative behavior of a class of physical systems by iterating a map on the vector space of interactions for the class. In a typical nonrigorous application of this technique, one assumes, based on one's physical intuition, that only a certain finite dimensional subspace (usually of dimension three or less) is important. The material in this book concerns a technique for justifying this approximation in a broad class of fermionic models used in condensed matter and high energy physics. This volume is based on the Aisenstadt Lectures given by Joel Feldman at the Centre de Recherches Mathematiques (Montreal, Canada). It is suitable for graduate students and research mathematicians interested in mathematical physics. Included are many problems and so...

On Bayesian treatment of systematic uncertainties in confidence interval calculation

CERN Document Server

Tegenfeldt, Fredrik

2005-01-01

In high energy physics, a widely used method to treat systematic uncertainties in confidence interval calculations is based on combining a frequentist construction of confidence belts with a Bayesian treatment of systematic uncertainties. In this note we present a study of the coverage of this method for the standard Likelihood Ratio (aka Feldman & Cousins) construction for a Poisson process with known background and Gaussian or log-Normal distributed uncertainties in the background or signal efficiency. For uncertainties in the signal efficiency of upto 40 % we find over-coverage on the level of 2 to 4 % depending on the size of uncertainties and the region in signal space. Uncertainties in the background generally have smaller effect on the coverage. A considerable smoothing of the coverage curves is observed. A software package is presented which allows fast calculation of the confidence intervals for a variety of assumptions on shape and size of systematic uncertainties for different nuisance paramete...

The evolution of conformist transmission in social learning when the environment changes periodically.

Science.gov (United States)

Nakahashi, Wataru

2007-08-01

Conformity is often observed in human social learning. Social learners preferentially imitate the majority or most common behavior in many situations, though the strength of conformity varies with the situation. Why has such a psychological tendency evolved? I investigate this problem by extending a standard model of social learning evolution with infinite environmental states (Feldman, M.W., Aoki, K., Kumm, J., 1996. Individual versus social learning: evolutionary analysis in a fluctuating environment. Anthropol. Sci. 104, 209-231) to include conformity bias. I mainly focus on the relationship between the strength of conformity bias that evolves and environmental stability, which is one of the most important factors in the evolution of social learning. Using the evolutionarily stable strategy (ESS) approach, I show that conformity always evolves when environmental stability and the cost of adopting a wrong behavior are small, though environmental stability and the cost of individual learning both negatively affect the strength of conformity.

Demonstration of resonant photopumping of Mo VII by Mo XII for a VUV laser near 600 Angstrom

International Nuclear Information System (INIS)

Ilcisin, K.J.; Aumayr, F.; Schwob, J.L.; Suckewer, S.

1993-09-01

We present data of experiments on the resonant photopumping of Mo VII by Mo XII as a method of generating a coherent VUV source near 600 angstrom. The experiment is based on a scheme proposed by Feldman and Reader in which the 4p 6 -- 4p 5 6s transition in Mo VII in resonantly photopumped by the 5s 2 S 1/2 -- 4p 2 P 1/2 transition in Mo XII. Results of the laser produced plasma experiments show the successful enhancement of the population of the Mo VII 4p 5 6s upper lasing level when pumped by an adjacent Mo VII plasma. No enhancement was seen in a control experiment where the Mo VII plasma was pumped by a Zr X plasma. Improvements of the intensity of the Mo XII pump source, achieved using an additional pump laser, lead to the generation of a population inversion for the VUV transition

Covariant description of Hamiltonian form for field dynamics

International Nuclear Information System (INIS)

Ozaki, Hiroshi

2005-01-01

Hamiltonian form of field dynamics is developed on a space-like hypersurface in space-time. A covariant Poisson bracket on the space-like hypersurface is defined and it plays a key role to describe every algebraic relation into a covariant form. It is shown that the Poisson bracket has the same symplectic structure that was brought in the covariant symplectic approach. An identity invariant under the canonical transformations is obtained. The identity follows a canonical equation in which the interaction Hamiltonian density generates a deformation of the space-like hypersurface. The equation just corresponds to the Yang-Feldman equation in the Heisenberg pictures in quantum field theory. By converting the covariant Poisson bracket on the space-like hypersurface to four-dimensional commutator, we can pass over to quantum field theory in the Heisenberg picture without spoiling the explicit relativistic covariance. As an example the canonical QCD is displayed in a covariant way on a space-like hypersurface

Curvature and the visual perception of shape: theory on information along object boundaries and the minima rule revisited.

Science.gov (United States)

Lim, Ik Soo; Leek, E Charles

2012-07-01

Previous empirical studies have shown that information along visual contours is known to be concentrated in regions of high magnitude of curvature, and, for closed contours, segments of negative curvature (i.e., concave segments) carry greater perceptual relevance than corresponding regions of positive curvature (i.e., convex segments). Lately, Feldman and Singh (2005, Psychological Review, 112, 243-252) proposed a mathematical derivation to yield information content as a function of curvature along a contour. Here, we highlight several fundamental errors in their derivation and in its associated implementation, which are problematic in both mathematical and psychological senses. Instead, we propose an alternative mathematical formulation for information measure of contour curvature that addresses these issues. Additionally, unlike in previous work, we extend this approach to 3-dimensional (3D) shape by providing a formal measure of information content for surface curvature and outline a modified version of the minima rule relating to part segmentation using curvature in 3D shape.

Optical fibre interferometer measurements on the H-1 heliac

Diagnostic techniques developed for discharge and plasma study, including electric and magnetic probes, optical and mass spectrometry, laser scattering, optical and microwave interferometry, Schlieren analysis, and laser Doppler anemometry (Huddlestone and Leonard, 1965) have limitations either with their range of application, their spatial resolution, or their disturbance of the discharge environment. Optical fibre sensors possess several attributes that make them attractive for probing electrical discharges and plasmas, including their insulating-nature, their small dimensions, and their immunity to high voltage and electromagnetic radiation. As insulators, optical fibres create none of the electrical disturbance or breakdown problems often associated with metal probes, and their small dimensions mean that distortion of discharge structure is minimised. With many discharges occurring in environments which are electromagnetically noisy and which involve high voltages and large inductive fields, signal transfer and processing through optical fibres provides significant benefits

Ever since Pythagoras hatched a 'little scheme' to invent a set of rules describing the entire universe, scientists and mathematicians have tried to seek order in the cosmos: Euclid, who in 300BC defined the nature of space; Descartes, a fourteenth-century gambler and idler who invented the graph; Gauss, the fifteen-year-old genius who discovered that space is curved; Einstein, who added time to the equation; and Witten, who ushered in today's weird new world of extra, twisted dimensions.

IMMEDIATE CONSTITUENT ANALYSIS (IC analysis DİREKT BİLEŞENLER ANALİZİ

Muzaffer MALKOÇ

2011-06-01

Full Text Available IC analysis is a method of sentence analysis first explicitly introduced by American linguist Leonard Bloomfield in his book, Language, in 1933, though the underlying principle is common both to the traditional practice of parsing and to many modern systems of grammatical analysis. In IC analysis, a sentence is divided up into major divisions or immediate constituents, and these constituents are in turn divided into further immediate constituents. This process continues until irreducible constituents are reached, i.e., until each constituent consists of only a word or meaningful part of a word. The important tests used to analyze the sentences are deletion, permutation, transformation, and substitution tests.The end result of an IC analysis is often presented in a visual diagrammatic form that reveals the hierarchical immediate constituent structure of a sentence Direkt bileşenler analiz metodu Amerikalı dil bilimci Leonard Bloomfield tarafından 1933 yılında sentaks alanında başlatılmış, daha sonraki yıllarda fonetik ve morfoloji alanlarında da uygulanmıştır. Bu analiz metodunun amacı tümce veya kelime gruplarının parçalanması ve tasnif edilmesi işleminden ibarettir. Tümcelerin parçalanması en küçük dil birimine kadar kademe kademe yapılmalı ve bileşenlerin sınıflandırılmasında ise ana öbeğe veya ana gövdeye daha yakın olan unsurlar ile ikincil öğeler analizin amacına uygun olarak belirtilmelidir. Bu işlemler yapılırken Yok Etme Testi, Yer Değiştirme Testi, Dönüştürme Testi, Yerine Koyma Testi gibi metotlardan faydalanılır. Bu prensipler çerçevesinde yapılan analizin sonuçları hiyerarşik yapıları göstermek için bir grafikle özetlenir

La Public Diplomacy : de John F. Kennedy à Tony Blair Public Diplomacy: From John F. Kennedy to Tony Blair

Vanessa Leclercq

2009-10-01

Full Text Available Public diplomacy was first implemented under the impulsion of John F. Kennedy and Edward R. Murrow by the United States Information Agency in the 1960s. This article emphasizes the critical role of public diplomacy in the fight against communism as well as the way the British authorities resorted to this concept almost forty years later to offer public opinion abroad a more modern and efficient image of the UK. In this perspective, it is legitimate to observe the evolution of both technology and the various media as well as to focus on Edward R. Murrow and Mark Leonard, Murrow’s British counterpart. Far from being mere communication, public diplomacy consists in the actual representation of a country’s policies and core values, and can therefore not avoid being assimilated to propaganda, even if it serves the noble purpose of information, not disinformation.

Nonlinear mathematical modeling of vibrating motion of nanomechanical cantilever active probe

Directory of Open Access Journals (Sweden)

Reza Ghaderi

Full Text Available Nonlinear vibration response of nanomechanical cantilever (NMC active probes in atomic force microscope (AFM application has been studied in the amplitude mode. Piezoelectric layer is placed piecewise and as an actuator on NMC. Continuous beam model has been chosen for analysis with regard to the geometric discontinuities of piezoelectric layer attachment and NMC's cross section. The force between the tip and the sample surface is modeled using Leonard-Jones potential. Assuming that cantilever is inclined to the sample surface, the effect of nonlinear force on NMC is considered as a shearing force and the concentrated bending moment is regarded at the end. Nonlinear frequency response of NMC is obtained close to the sample surface using the dynamic modeling. It is then become clear that the distance and angle of NMC, the probe length, and the geometric dimensions of piezoelectric layer can affect frequency response bending of the curve.

From Fact to Fiction – An Introduction to the Mythology of Ice Hockey in Canadian Life and Literature

Directory of Open Access Journals (Sweden)

Jason Blake

2004-12-01

Full Text Available The title of Alice Munro’s Who do you think you are? could just as easily be asked of Canada, without eliciting an easy answer. In ethnic, linguistic, even geographical terms, Canada is hardly homogeneous. Because of this, we can only dream of a unified identity; we are, as Leonard Cohen writes in Beautiful Losers, condemned to “nightmares of identity.” If Canada is too complex for a uniform national identity, one derived from a convenient mythology and distilled into simple symbols, it often seems we have yet to realize it. We long for a mythology, even a modern, and blatantly constructed one. In contemporary Canadian society, ice hockey has filled that symbolic role, serving as a mythology that binds a fragmented people. This paper examines the role of ice hockey as a mythologized symbol of Canadian unity in literature, and questions the appropriateness of that usage.

Edmondson, Richard; Light, Kenneth; Bodenhamer, Andrew; Bosscher, Paul; Wilkinson, Loren

2012-06-01

Polaris Sensor Technologies (PST) has developed a stereo vision upgrade kit for TALON® robot systems comprised of a replacement gripper camera and a replacement mast zoom camera on the robot, and a replacement display in the Operator Control Unit (OCU). Harris Corporation has developed a haptic manipulation upgrade for TALON® robot systems comprised of a replacement arm and gripper and an OCU that provides haptic (force) feedback. PST and Harris have recently collaborated to integrate the 3D vision system with the haptic manipulation system. In multiple studies done at Fort Leonard Wood, Missouri it has been shown that 3D vision and haptics provide more intuitive perception of complicated scenery and improved robot arm control, allowing for improved mission performance and the potential for reduced time on target. This paper discusses the potential benefits of these enhancements to robotic systems used for the domestic homeland security mission.

Lexicalisation Patterns in Danish and Spanish

DEFF Research Database (Denmark)

Woldersgaard, Casper A. G

In this dissertation, I investigate the theoretical framework by Leonard Talmy (2000b) on lexicalisation patterns in Motion events. I examine his characterisations of Co-event languages (e.g., Danish) and Path-event languages (e.g., Spanish), and I relate his work to a Danish language setting....... Furthermore, my objective is to determine whether the predictions set forth by Talmy apply to Danish and Spanish from an empirical perspective, i.e., in a Danish monolingual reference corpus, Korpus-DK, and a Spanish monolingual reference corpus, CORPES. I present different methods for testing Talmy’s theory....... As a consequence, to identify Motion events and discard false positives is an extremely time-consuming process. I suggest that a context-free grammar is a way to facilitate the retrieval and analysis of linguistic data that contain Motion events. Thus, I implement a context-free grammar for Spanish. More...

Review of numerical methods for radionuclide transport in 3d porous media at high Peclet numbers

International Nuclear Information System (INIS)

Spalding, D.B.; Pun, W.M.

1986-10-01

This programme of work considers the relative accuracy exhibited by several alternative means of formulating the advection - diffusion equation, in three dimensions, with particular reference to the limitation of computing resources. It is concluded that the accuracy depends mainly on the formula used for the average concentration of pollutant in the fluid in a computational cell during a given time step. This average value of concentration is reasonably regarded as the weighted average of the upstream, downstream and neighbour values at the start and finish of the time step and the cell surface dimensions. Of the formulations surveyed, those of Leith and Leonard performed best, albeit with a tendency to develop non-physical overshoots. The fully explicit upwind formulation performed worst of all but was free from the non-physical problem. In general the moving grid formulation performed most satisfactorily when applied to many practical situations. (author)

The adventures of climate science in the sweet land of idle arguments

Science.gov (United States)

Winsberg, Eric; Goodwin, William Mark

2016-05-01

In a recent series of papers Roman Frigg, Leonard Smith, and several coauthors have developed a general epistemological argument designed to cast doubt on the capacity of a broad range of mathematical models to generate "decision relevant predictions." The presumptive targets of their argument are at least some of the modeling projects undertaken in contemporary climate science. In this paper, we trace and contrast two very different readings of the scope of their argument. We do this by considering the very different implications for climate science that these interpretations would have. Then, we lay out the structure of their argument-an argument by analogy-with an eye to identifying points at which certain epistemically significant distinctions might limit the force of the analogy. Finally, some of these epistemically significant distinctions are introduced and defended as relevant to a great many of the predictive mathematical modeling projects employed in contemporary climate science.

The theoretical minimum what you need to know to start doing physics

CERN Document Server

Susskind, Leonard

2013-01-01

In this unconventional and stimulating primer, world-class physicist Leonard Susskind and citizen-scientist George Hrabovsky combine forces to provide a brilliant first course in modern physics. Unlike most popular physics books - which give readers a taste of what physicists know but not what they actually do - Susskind and Hrabovsky teach the skills you need to do physics yourself. Combining crystal-clear explanations of the laws of the universe with basic exercises, the authors cover the minimum - the theoretical minimum of the title - that readers need to master in order to study more advanced topics. In a lucid, engaging style, they introduce all the key concepts, from classical mechanics to general relativity to quantum theory. Instead of shying away from the equations and maths that are essential to any understanding of physics, The Theoretical Minimum provides a toolkit that you won't find in any other popular science book.

Harmonic and reactive behavior of the quasiparticle tunnel current in SIS junctions

2016-04-15

In this paper, we show theoretically and experimentally that the reactive quasiparticle tunnel current of the superconductor tunnel junction could be directly measured at specific bias voltages for the higher harmonics of the quasiparticle tunnel current. We used the theory of quasiparticle tunneling to study the higher harmonics of the quasiparticle tunnel current in superconducting tunnel junction in the presence of rf irradiation. The impact of the reactive current on the harmonic behavior of the quasiparticle tunnel current was carefully studied by implementing a practical model with four parameters to model the dc I-V characteristics of the superconducting tunnel junction. The measured reactive current at the specific bias voltage is in good agreement with our theoretically calculated reactive current through the Kramers-Kronig transform. This study also shows that there is an excellent correspondence between the behavior of the predicted higher harmonics using the previously established theory of quasiparticle tunnel current in superconducting tunnel junctions by J.R. Tucker and M.J. Feldman and the measurements presented in this paper.

The binding of glucose to yeast hexokinase monomers is independent of ionic strength.

Mayes, E L; Hoggett, J G; Kellett, G L

1982-05-01

Hoggett & Kellett [Eur. J. Biochem. 66, 65-77 (1976)] have reported that the binding of glucose to the monomer of hexokinase PII isoenzyme is independent of ionic strength, in contrast to the subsequent claim of Feldman & Kramp [Biochemistry 17, 1541-1547 (1978)] that the binding is strongly dependent on ionic strength. Since measurements with native hexokinase P forms are complicated by the fact that the enzyme exists in a monomer-dimer association-dissociation equilibrium, we have now studied the binding of glucose to the proteolytically-modified S forms which are monomeric. At pH 8.5, the affinity of glucose for both SI and SII monomers is independent of salt concentration over the range of KCl concentrations 0-1.0 mol . dm-3 and is in good agreement with that of the corresponding P forms in both low and high salt. These observations confirm that the binding of glucose to hexokinase P monomers is independent of ionic strength and that the affinity of glucose for the hexokinase PII monomer is about an order of magnitude greater than that for the dimer.

How should neuroscience study emotions? by distinguishing emotion states, concepts, and experiences.

Science.gov (United States)

Adolphs, Ralph

2017-01-01

In this debate with Lisa Feldman Barrett, I defend a view of emotions as biological functional states. Affective neuroscience studies emotions in this sense, but it also studies the conscious experience of emotion ('feelings'), our ability to attribute emotions to others and to animals ('attribution', 'anthropomorphizing'), our ability to think and talk about emotion ('concepts of emotion', 'semantic knowledge of emotion') and the behaviors caused by an emotion ('expression of emotions', 'emotional reactions'). I think that the most pressing challenge facing affective neuroscience is the need to carefully distinguish between these distinct aspects of 'emotion'. I view emotion states as evolved functional states that regulate complex behavior, in both people and animals, in response to challenges that instantiate recurrent environmental themes. These functional states, in turn, can also cause conscious experiences (feelings), and their effects and our memories for those effects also contribute to our semantic knowledge of emotions (concepts). Cross-species studies, dissociations in neurological and psychiatric patients, and more ecologically valid neuroimaging designs should be used to partly separate these different phenomena. © The Author (2016).

We present the first in situ observations of heavy ion dropouts within the slow solar wind, observed for select elements ranging from helium to iron. For iron, these dropouts manifest themselves as depletions of the Fe/H ratio by factors up to {approx}25. The events often exhibit mass-dependent fractionation and are contained in slow, unsteady wind found within a few days from known stream interfaces. We propose that such dropouts are evidence of gravitational settling within large coronal loops, which later undergo interchange reconnection and become source regions of slow, unsteady wind. Previously, spectroscopic studies by Raymond et al. in 1997 (and later Feldman et al. in 1999) have yielded strong evidence for gravitational settling within these loops. However, their expected in situ signature plasma with heavy elements fractionated by mass was not observed prior to this study. Using data from the SWICS instrument on board the Advanced Composition Explorer (ACE), we investigate the composition of the solar wind within these dropouts and explore long term trends over most of a solar cycle.

We present the first in situ observations of heavy ion dropouts within the slow solar wind, observed for select elements ranging from helium to iron. For iron, these dropouts manifest themselves as depletions of the Fe/H ratio by factors up to ∼25.

A New Non-LTE Model based on Super Configurations

Bar-Shalom, A.; Klapisch, M.

1996-11-01

Non-LTE effects are vital for the simulation of radiation in hot plasmas involving even medium Z materials. However, the exceedingly large number of atomic energy levels forbids using a detailed collisional radiative model on-line in the hydrodynamic simulations. For this purpose, greatly simplified models are required. We implemented recently Busquet's model(M. Busquet, Phys. Fluids B, 5, 4191 (1993)) in NRL's RAD2D Hydro code in conservative form (M. Klapisch et al., Bull. Am. Phys. Soc., 40, 1806 (1995), and poster at this meeting.). This model is quick and the results make sense, but in the absence of precisely defined experiments, it is difficult to asses its accuracy. We present here a new collisional radiative model based on superconfigurations( A. Bar-Shalom, J. Oreg, J. F. Seely, U. Feldman, C. M. Brown, B. A. Hammel, R. W. Lee and C. A. Back, Phys. Rev. E, 52, 6686 (1995).), intended to be a benchmark for approximate models used in hydro-codes. It uses accurate rates from the HULLAC Code. Results for various elements will be presented and compared with RADIOM.

AlN films with thickness from 100 to 1000 nm were grown on SiC substrate by MBE. AlN crystalline films were doped by implantation with 160 keV Tb ions to fluences of 5x10 14 , 1.5x10 15 , 3x10 15 and 6x10 15 ions/cm 2 , respectively. The damage profiles in AlN films induced by Tb implantation were investigated using RBS/channeling technique. A procedure developed by Feldman and Rodgers was used to extract damage profile by considering the dechanneling mechanism of multiple. The comparison of the extracted profile with TRIM prediction shows a significant difference in the shape and in the position of damage profile. The damage profile in AlN film is similar as Tb distribution. The RBS/channeling of Tb-implanted AlN film before and after 950 deg. C annealing treatments show a good consistency, which indicate that high temperature annealing cannot result in a significant change in both crystal damage and in Tb distribution

From Wald to Savage: homo economicus becomes a Bayesian statistician.

Science.gov (United States)

Giocoli, Nicola

2013-01-01

Bayesian rationality is the paradigm of rational behavior in neoclassical economics. An economic agent is deemed rational when she maximizes her subjective expected utility and consistently revises her beliefs according to Bayes's rule. The paper raises the question of how, when and why this characterization of rationality came to be endorsed by mainstream economists. Though no definitive answer is provided, it is argued that the question is of great historiographic importance. The story begins with Abraham Wald's behaviorist approach to statistics and culminates with Leonard J. Savage's elaboration of subjective expected utility theory in his 1954 classic The Foundations of Statistics. The latter's acknowledged fiasco to achieve a reinterpretation of traditional inference techniques along subjectivist and behaviorist lines raises the puzzle of how a failed project in statistics could turn into such a big success in economics. Possible answers call into play the emphasis on consistency requirements in neoclassical theory and the impact of the postwar transformation of U.S. business schools. © 2012 Wiley Periodicals, Inc.

Aquinas and Contemporary Cosmology: Creation and Beginnings

Science.gov (United States)

Carroll, William E.

Discussions in the Middle Ages about creation and the temporal beginning of the world involved sophisticated analyses in theology, metaphysics, and natural philosophy. Mediaeval insights on this subject, especially Thomas Aquinas' defense of the intelligibility of an eternal, created universe, can help to clarify reflections about the philosophical and theological implications of contemporary cosmological theories: from the "singularity" of the Big Bang, to "quantum tunneling from nothing," to multiverse scenarios. Thomas' insights help us to see the value of Georges Lemaître's insistence that his cosmological reflections must be kept separate from an analysis of creation. This essay will look at different senses of "beginning" and examine the claim that creation, in its fundamental meaning, tells us nothing about whether there is a temporal beginning to the universe. Multiverse models, like that recently proposed by Stephen Hawking and Leonard Mlodinow, may challenge certain views of a Grand Designer, but not of a Creator.

The Eighth Rochester Conference on Coherence and Quantum Optics was held on the campus of the University of Rochester during the period June 13-16,2001. This volume contains the proceedings of the meeting. The meeting was preceded by an affiliated conference, the International Conference on Quantum Information, with some overlapping sessions on June 13. The proceedings of the affiliated conference will be published separately by the Optical Society of America. A few papers that were presented in common plenary sessions of the two conferences will be published in both proceedings volumes. More than 268 scientists from 28 countries participated in the week long discussions and presentations. This Conference differed from the previous seven in the CQO series in several ways, the most important of which was the absence of Leonard Mandel. Professor Mandel died a few months before the conference. A special memorial symposium in his honor was held at the end of the conference. The presentations from that sym...

Characteristics of Criteria for Selecting Investment Projects under Uncertainty

Full Text Available Within financial theory and practice, there are used five main criteria for selecting investment projects: the net present value (NPV criterion, the internal rate of return (IRR criterion, the return term (RT criterion, the profitability ratio (PR criterion and the supplementary return (SR criterion. The assay will emphasize several new properties of said indexes for investment assessment, having as starting point the hypotheses of (approximately normal repartition of cash-flows generated by an investment project. The obtained results point to the fact that the NPV indexes (the analysis of this criterion was carried out in the article “The NPV Criterion for Valuing Investments under Uncertainty”, Daniel Armeanu, Leonard Lache, Economic Computation and Economic Cybernetics Studies and Research no. 4/2009, pp. 133-143, IRR, PR, RT and SR register normal repartitions, therefore simplifying the investment analysis under economic uncertainty, by the capacity of building confidence intervals and assessing probabilities for the inferior limits of said investment assessment indexes.

Functional connectivity changes in the language network (Price, 2010), and in a control network involved in second language (L2) processing (Abutalebi & Green, 2007) were examined in a group of Persian (L1) speakers learning French (L2) words. Measures of network integration that characterize the global integrative state of a network (Marrelec, Bellec et al., 2008) were gathered, in the shallow and consolidation phases of L2 vocabulary learning. Functional connectivity remained unchanged across learning phases for L1, whereas total, between- and within-network integration levels decreased as proficiency for L2 increased. The results of this study provide the first functional connectivity evidence regarding the dynamic role of the language processing and cognitive control networks in L2 learning (Abutalebi, Cappa, & Perani, 2005; Altarriba & Heredia, 2008; Leonard et al., 2011; Parker-Jones et al., 2011). Thus, increased proficiency results in a higher degree of automaticity and lower cognitive effort (Segalowitz & Hulstijn, 2005). Copyright © 2012 Elsevier Inc. All rights reserved.

Molecular bases of cellular senescence: Hayflick phenomenon 50 years later

Directory of Open Access Journals (Sweden)

Patrycja Sosińska

2016-03-01

Full Text Available Normal human somatic cells have strictly limited proliferative capacity and reach a state of senescence when it becomes exhausted. It is believed that senescence is a response to extensive and irreparable DNA injury, localized in telomeric and/or non-telomeric regions of the genome. Main cause of this damage is oxidative stress, increasing due to deteriorated function of mitochondria. Senescent cells accumulate in tissues during aging, which is causatively linked with the development of various pathologies in elderly individuals, including cancer. This paper, prepared exactly 50 years after Leonard Hayflick’s discovery of the relationship between cellular senescence and organismal aging is aimed at presenting the current knowledge about molecular determinants of senescence, with particular emphasis paid to the role of oxidative stress, effectors of senescence at the level of cell cycle, markers of this phenomenon, and the effect of senescent cells on the development of certain age-related diseases.

Froehle, Andrew W; Schoeninger, Margaret J

2006-12-01

We conducted a meta-analysis of 45 studies reporting basal metabolic rate (BMR) data for Homo sapiens and Pan troglodytes to determine the effects of sex, age, and latitude (a proxy for climate, in humans only). BMR was normalized for body size using fat-free mass in humans and body mass in chimpanzees. We found no effect of sex in either species and no age effect in chimpanzees. In humans, juveniles differed significantly from adults (ANCOVA: P BMR and body size, and used them to predict total daily energy expenditure (TEE) in four early hominin species. Our predictions concur with previous TEE estimates (i.e. Leonard and Robertson: Am J Phys Anthropol 102 (1997) 265-281), and support the conclusion that TEE increased greatly with H. erectus. Our results show that intraspecific variation in BMR does not affect TEE estimates for interspecific comparisons. Comparisons of more closely related groups such as humans and Neandertals, however, may benefit from consideration of this variation. 2006 Wiley-Liss, Inc.

Farewell to reality how modern physics has betrayed the search for scientific truth

CERN Document Server

Baggott, Jim

2013-01-01

From acclaimed science author Jim Baggott, a pointed critique of modern theoretical physics. In this stunning new volume, Jim Baggott argues that there is no observational or experimental evidence for many of the ideas of modern theoretical physics: super-symmetric particles,super strings, the multiverse, the holographic principle,or the anthropic cosmological principle. These theories are not only untrue, it is not even science. It is fairy-tale physics: fantastical, bizarre and often outrageous, perhaps even confidence-trickery. This book provides a much-needed antidote. Informed,comprehensive, and balanced, it offers lay readers the latest ideas about the nature of physical reality while clearly distinguishing between fact and fantasy. With its engaging portraits of many central figures of modern physics, including Paul Davies, John Barrow, Brian Greene, Stephen Hawking, and Leonard Susskind, it promises to be essential reading for all readers interested in what we know and don’t know about the nature of...

Non-Traditional Security Threats in the Border Areas: Terrorism, Piracy, Environmental Degradation in Southeast Asian Maritime Domain

Science.gov (United States)

Dabova, E. L.

2013-11-01

In addition to facilitating peaceful trade and economic development, sovereign territory, territorial waters and international waters are being used by various criminal groups that pose threats to governments, businesses and civilian population in Southeast Asia. Nonstate criminal maritime activities were not receiving appropriate attention as they were overshadowed by traditional military security challenges. Yet more and more frequently, the non-traditional actors challenge lines of communication, jeopardize access to strategic resources, complicate traditional defence tasks, and harm the environment. Understanding the nature of non-traditional threats, and the ways to combat them, requires international legal, historical and political science analysis within a united problem-oriented approach. A fair critique to pure interest, power and knowledge -based theories of regime formation was developed by E.K. Leonard's1, who explained the evolution of the international system from the global governance perspective. The present study is based on the premise that pure nation-state approaches are incapable of providing a theoretical ground for addressing the growing influence of international criminal networks in South East Asia. From an international relations theory perspective, the author of this study agrees with D.Snidal2 that the hegemonic stability theory has "limits" and is insufficient in describing modern challenges to sustainable international security regime, including non-traditional threats, where collective action is more efficient from an interest and capability standpoint. At the same time the author of this study does not share the viewpoint on "marginalization"3 of international law in current international order due to its fragmentation and regionalization4 and "global power shifts"5 . The United Nations, as a global institution at the top of the vertical hierarchy of international legal order, and the EU as an example of "self-contained" regime along

The effects of ionizing radiation on some biological parameters in rats have been studied. Sublethal whole body g-irradiation dose on the plasma lipid fractions and susceptibility to oxidative stress were investigated. Male albino rats were intraperitoneally injected with a-tocopheryl acetate (200 mg/kg body weight), and/or sodium selenite (0.1 mg/kg body weight), daily for two weeks before exposure to 6.5 Gy of ionizing radiation. Exposed rats to ionizing radiation showed significant alterations in the assayed parameters indicating lipid metabolism disturbances. The combined administration of a-tocopherol and selenium greatly ameliorated the increase in total cholesterol, triacylglycerols, phospholipids, low-density lipoprotein- cholesterol concentration in plasma. Moreover, the data revealed an increased consumption of vitamin E concentration in plasma following g-rays exposure. Vitamin E/triacylglycerols ratio was greatly corrected by combined administration of vitamin E and Selenium. Cholesterol has a long scientific history being representing a major essential constituent for all animal cell membranes (Gurr and Harwood, 1992). Plasma lipid levels are affected by genetic and dietary factors, medication and certain primary disease states (Feldman and Kuske, 1989). Hyperlipemia may occur due to exposure to ionizing radiation resulting in accumulation of cholesterol,

The logical primitives of thought: Empirical foundations for compositional cognitive models.

The notion of a compositional language of thought (LOT) has been central in computational accounts of cognition from earliest attempts (Boole, 1854; Fodor, 1975) to the present day (Feldman, 2000; Penn, Holyoak, & Povinelli, 2008; Fodor, 2008; Kemp, 2012; Goodman, Tenenbaum, & Gerstenberg, 2015). Recent modeling work shows how statistical inferences over compositionally structured hypothesis spaces might explain learning and development across a variety of domains. However, the primitive components of such representations are typically assumed a priori by modelers and theoreticians rather than determined empirically. We show how different sets of LOT primitives, embedded in a psychologically realistic approximate Bayesian inference framework, systematically predict distinct learning curves in rule-based concept learning experiments. We use this feature of LOT models to design a set of large-scale concept learning experiments that can determine the most likely primitives for psychological concepts involving Boolean connectives and quantification. Subjects' inferences are most consistent with a rich (nonminimal) set of Boolean operations, including first-order, but not second-order, quantification. Our results more generally show how specific LOT theories can be distinguished empirically. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Neurologizing the Psychology of Affects: How Appraisal-Based Constructivism and Basic Emotion Theory Can Coexist.

Science.gov (United States)

Panksepp, Jaak

2007-09-01

Abundant neurobehavioral data, not discussed by Lisa Feldman Barrett (2006), support the existence of a variety of core emotional operating systems in ancient subneocortical regions of the brain (Panksepp, 1998a, 2005a). Such brain systems are the primary-process ancestral birthrights of all mammals. There may be as many genetically and neurochemically coded subcortical affect systems in emotionally rich medial regions of the brain as there are "natural" emotional action systems in the brain. When emotional primes are aroused directly, as with local electrical or chemical stimulation, the affective changes sustain conditioned place preferences and place aversions, which are the premier secondary-process indices of affective states in animals. Humans are not immune to such brain manipulations; they typically exhibit strong emotional feelings. Human emotion researchers should not ignore these systems and simply look at the complex and highly variable culturally molded manifestations of emotions in humans if they wish to determine what kinds of "natural" emotional processes exist within all mammalian brain. Basic emotion science has generated workable epistemological strategies for under-standing the primal sources of human emotional feelings by detailed study of emotional circuits in our fellow animals. © 2007 Association for Psychological Science.

Searches for two-body charmless baryonic $B^0$ decays at LHCb

AUTHOR|(CDS)2083570; Eklund, Lars

2016-09-26

The results of two separate searches for the rare two-body charmless baryonic decays B0 -> p pbar and B0s -> p pbar at the LHCb experiment are reported in this thesis. The first analysis uses a data sample, corresponding to an integrated luminosity of 0.9 fb^-1, of proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. An excess of B0 -> p pbar candidates with respect to background expectations is seen with a statistical significance of 3.3 standard deviations. This constitutes the first evidence for a two-body charmless baryonic B0 decay. No significant B0s -> p pbar signal was observed. However, a small excess of B0s -> p pbar events allowed the extraction of two sided confidence level intervals for the B0s -> p pbar branching fraction using the Feldman-Cousins frequentist method. This improved the upper limit on the B0s -> p pbar branching fraction by three orders of magnitude over previous bounds. The 68.3% confidence level intervals on the branching fractions w...

The present study had two aims: (a) to replicate previous findings regarding the characteristics of sudden gains (SGs) in psychotherapy under routine clinical conditions and (b) to examine whether clients' narrative meaning-making processes were associated with SGs in mental health. 54 psychotherapy clients completed the Systemic Therapy Inventory of Change (Pinsof et al., 2009) and wrote private narratives prior to beginning treatment and between every session for 12 assessment points over the course of psychotherapy for a variety of presenting problems. Clients' narratives were coded using existing systems (Adler, 2012; A. M. Hayes, Feldman, & Goldfried, 2006) to assess their content in eight themes: processing, avoidance, coherence, positive self, negative self, agency, hope, and hopelessness. The prevalence, magnitude, and timing of SGs in mental health observed in the present study were similar to those observed in prior research. Two narrative meaning-making processes-processing and coherence-were significantly associated with SGs in mental health. The present study significantly extends prior research on SGs, replicating the characteristics of these gains in routine clinical conditions with a measure of general functioning and identifying two narrative meaning-making processes that are associated with SGs in mental health.

We present searches for the rare decay modes D{sup 0} {yields} e{sup +}e{sup -}, D{sup 0} {yields} {mu}{sup +}{mu}{sup -}, and D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}} in continuum e{sup +}e{sup -} {yields} c{bar c} events recorded by the BABAR detector in a data sample that corresponds to an integrated luminosity of 468 fb{sup -1}. These decays are highly GIM suppressed but may be enhanced in several extensions of the Standard Model. Our observed event yields are consistent with the expected backgrounds. An excess is seen in the D{sup 0} {yields} {mu}{sup +}{mu}{sup -} channel, although the observed yield is consistent with an upward background fluctuation at the 5% level. Using the Feldman-Cousins method, we set the following 90% confidence level intervals on the branching fractions: {Beta}(D{sup 0} {yields} e{sup +}e{sup -}) < 1.7 x 10{sup -7}, {Beta}(D{sup 0} {yields} {mu}{sup +}{mu}{sup -}) within [0.6, 8.1] x 10{sup -7}, and {Beta}(D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}) < 3.3 x 10{sup -7}.

How should neuroscience study emotions? by distinguishing emotion states, concepts, and experiences

Science.gov (United States)

2017-01-01

Abstract In this debate with Lisa Feldman Barrett, I defend a view of emotions as biological functional states. Affective neuroscience studies emotions in this sense, but it also studies the conscious experience of emotion (‘feelings’), our ability to attribute emotions to others and to animals (‘attribution’, ‘anthropomorphizing’), our ability to think and talk about emotion (‘concepts of emotion’, ‘semantic knowledge of emotion’) and the behaviors caused by an emotion (‘expression of emotions’, ‘emotional reactions’). I think that the most pressing challenge facing affective neuroscience is the need to carefully distinguish between these distinct aspects of ‘emotion’. I view emotion states as evolved functional states that regulate complex behavior, in both people and animals, in response to challenges that instantiate recurrent environmental themes. These functional states, in turn, can also cause conscious experiences (feelings), and their effects and our memories for those effects also contribute to our semantic knowledge of emotions (concepts). Cross-species studies, dissociations in neurological and psychiatric patients, and more ecologically valid neuroimaging designs should be used to partly separate these different phenomena.

Workshop on confidence limits. Proceedings

James, F.; Lyons, L.; Perrin, Y.

2000-01-01

The First Workshop on Confidence Limits was held at CERN on 17-18 January 2000. It was devoted to the problem of setting confidence limits in difficult cases: number of observed events is small or zero, background is larger than signal, background not well known, and measurements near a physical boundary. Among the many examples in high-energy physics are searches for the Higgs, searches for neutrino oscillations, B s mixing, SUSY, compositeness, neutrino masses, and dark matter. Several different methods are on the market: the CL s methods used by the LEP Higgs searches; Bayesian methods; Feldman-Cousins and modifications thereof; empirical and combined methods. The Workshop generated considerable interest, and attendance was finally limited by the seating capacity of the CERN Council Chamber where all the sessions took place. These proceedings contain all the papers presented, as well as the full text of the discussions after each paper and of course the last session which was a discussion session. The list of participants and the 'required reading', which was expected to be part of the prior knowledge of all participants, are also included. (orig.)

Unbiased contaminant removal for 3D galaxy power spectrum measurements

2016-11-01

We assess and develop techniques to remove contaminants when calculating the 3D galaxy power spectrum. We separate the process into three separate stages: (I) removing the contaminant signal, (II) estimating the uncontaminated cosmological power spectrum and (III) debiasing the resulting estimates. For (I), we show that removing the best-fitting contaminant (mode subtraction) and setting the contaminated components of the covariance to be infinite (mode deprojection) are mathematically equivalent. For (II), performing a quadratic maximum likelihood (QML) estimate after mode deprojection gives an optimal unbiased solution, although it requires the manipulation of large N_mode^2 matrices (Nmode being the total number of modes), which is unfeasible for recent 3D galaxy surveys. Measuring a binned average of the modes for (II) as proposed by Feldman, Kaiser & Peacock (FKP) is faster and simpler, but is sub-optimal and gives rise to a biased solution. We present a method to debias the resulting FKP measurements that does not require any large matrix calculations. We argue that the sub-optimality of the FKP estimator compared with the QML estimator, caused by contaminants, is less severe than that commonly ignored due to the survey window.

Full Text Available The role of technological innovation in enhancing competitive advantage at the level of individual companies and industries, regions, and even countries, has increased interest in the innovation component of the cluster, and has led to revision of the concept of the treatment of cluster effects and of approaches to their study. As a result of theoretical research and analysis of practical situations, in the late 1990s W. Feldman and J. Audretsch developed a theory of economic development through the establishment of innovation clusters. In this paper we aim to identify the quantitative link between the participation in innovation clusters and universities, research centres, and other institutes of innovative development; we will also try to find the key factors affecting them. We used econometric procedures for 413 companies (based on the data of accounting and statistical reports of the Perm region (Russia. The regression outcomes allow defining the ‘stimulating’ factors affecting participation in cluster relationships. The quantitative analysis was supplemented by in-depth interviews on different types of relationship forms among companies and institutes promoting innovation within the framework of a cluster concept.

Full Text Available The development of self-regulation in early childhood is related to development of emotional regulation and attention, in particular executive attention (Feldman, 2009; Posner & Rothbart, 1998. As the ability to self-regulate is crucial in life (Casey et al., 2011, it is important to reveal early predictors of self-regulation. The aim of the paper is to present the results of longitudinal studies on the relationships between the functioning of attention, regulation of emotion and later self-regulatory abilities. 310 children were assessed at three time points. At 12 months of age emotional regulation in situation of frustration and attention regulation were assessed. At 18 and 24 months behavioral-emotional regulation in the Snack Delay Task was measured. Additionally parents assessed executive attention using The Early Childhood Behavior Questionnaire when children were 26 months old. Structural equation modelling revealed two different paths to development of self-regulatory abilities at 18 months: emotional (reactive system and emotionalattentional and only one emotional-attentional path at 24 months. The early ability to focus attention and later executive attention functioning revealed to be important predictors of self-regulatory abilities both at 18 and 24 months of age.

The unclear etiology of rosacea fosters therapeutic difficulty; however, subtle clinical improvement with pharmacologic treatments of various drug categories suggests a multifactorial etiology of the disease. Factors that may contribute to disease pathogenesis include immune abnormality, vascular abnormality, neurogenic dysregulation, presence of cutaneous microorganisms, UV damage, and skin barrier dysfunction. The role of ivermectin in the treatment of rosacea may be as an anti-inflammatory and anti-parasitic agent targeting Demodex mites. In comparing topical ivermectin and metronidazole, ivermectin was more effective; this treatment modality boasted more improved quality of life, reduced lesion counts, and more favorable participant and physician assessment of disease severity. Patients who received ivermectin 1% cream had an acceptable safety profile. Ivermectin is efficacious in decreasing inflammatory lesion counts and erythema.

Full Text Available Severe word production difficulties remain one of the most challenging clinical symptoms to treat in individuals with jargon aphasia (JA. Although research has found a beneficial effect of phonological therapy in JA (e.g., FF in Bose 2013; GF in Robson et al., 1998, a lack of improvement in naming performance following this approach has also been reported (e.g., P9 in Leonard et al., 2008. Clinically, it is important to determine why some individuals with JA improve following phonological therapy when others do not. This research investigates the effect of phonological therapy on naming performance in JA and explores possible reasons for improvement or lack thereof (e.g., input/ output processing skills, ability to use and maintain cues. Methods Participant: AM, an 86 year old, English-speaking male, was 16 years post-stroke and presented with persistent, severe neologistic jargon, characterized by very high proportions of non-words and perseverations. Part 1: Effects of phonological cuing (initial phoneme vs. semantic cuing (semantically-related item on naming performance were tested on items from the Philadelphia Naming Test (Roach et al., 1996 to determine the most suitable course of therapy. Part 2: Using a single-subject multiple baseline design, Phonological Component Analysis (Leonard et al., 2008 was administered for three sets of words. In addition to analysis of therapy performance, naming accuracy was compared across three lists in three instances of a word being treated (i.e., 1st attempt without any phonological cues, 2nd attempt immediately after the phonological cues, and 3rd attempt after review of the phonological cues. Results and Discussion Part 1: Results showed a significant increase in naming accuracy following phonological cuing [χ2 (1 = 5.782, p = .01], whereas semantic cuing did not [χ2 (1 =.386, ns], thus motivating the implementation of a phonological therapy.

Circumvention of the Mycobactin Requirement of Mycobacterium paratuberculosis

Morrison, Norman E. (Johns Hopkins University-Leonard Wood Memorial Leprosy Research Laboratory, Baltimore, Md.). Circumvention of the mycobactin requirement of Mycobacterium paratuberculosis. J. Bacteriol. 89:762–767. 1965.—The mycobactin growth requirement of Mycobacterium paratuberculosis was circumvented on glucose-containing synthetic medium with an initial pH of 5.5. Mycobactin was required during the first transfer on the synthetic medium. Subsequent transfers have grown in the absence of mycobactin. The growth of mycobactin-“independent” strains of M. paratuberculosis on the synthetic medium was found to be stimulated by low concentrations of mycobactin. The circumvention of the mycobactin requirement appears to depend upon the properties of the medium and not upon having created conditions which promote endogenous mycobactin synthesis. Investigation of the glucose-containing synthetic medium showed that: (i) growth stimulatory compounds were formed during autoclaving, and (ii) compared with neutrality a pH of 5.5 gave markedly increased pellicle yields. It was suggested that the growth-stimulatory compounds formed during autoclaving may in part be responsible for the circumvention of the mycobactin requirement. PMID:14273658

Why Not Study Polytonal Psychophysics?

2007-01-01

Full Text Available The relative consonance/dissonance of 2-tone intervals is well understood both experimentally and theoretically and provides a strong foundation for explaining why diatonic scales or their subsets are used in most musical cultures. Frequent textbook assertions notwithstanding, however, the consonance of intervals fails to account for the basic facts of harmony (3 or more tone combinations. We have recently shown (Cook & Fujisawa, 2006 how consideration of 3-tone psychophysics can explain the fundamental regularities of diatonic harmony. Distinct from the dissonance of 2-tone intervals, 3-tone combinations introduce an effect described by Leonard Meyer (1956 as harmonic “tension”: when a third tone is located midway between an upper and a lower tone, the chord takes on an unresolved, unstable, tense character – a psychoacoustical property inherent to the diminished and augmented chords. If the effects of the upper partials are included in a formal model that includes both 2-tone and 3-tone effects, the perceived sonority of the triads (major>minor> diminished>augmented is easily explained.

Eating patterns, diet quality and energy balance: from the macro- to the microscopic.

Lowe, Michael R

2014-07-01

As a discussant for the 2013 IBRC Symposium on Eating Patterns, Diet Quality and Energy Balance at Purdue University, I describe here several reflections I had on the papers as a whole. I initially focus on the keynote address by Dr. Leonard. His address suggested that the evolutionary development of Homo sapiens during the past 2 million years may have "prepared" humans to seek and consume food beyond their immediate energy needs, a predisposition that may have rendered humans particularly vulnerable to modern food environments. Additional observations include: 1) the importance of differentiating between a given appetitive variable (e.g., snacking) as a potential cause versus consequence of an outcome of interest (e.g., obesity), 2) the need to move beyond research on the consummatory phase of appetite to the anticipatory phase of appetite, and 3) the opportunity that exists to take the many obesogenic nutritional influences documented in the symposium and "turn them on their heads" to facilitate, rather than undermine, long-term weight control.

A play portfolio is being constructed for the Permian Basin in west Texas and southeast New Mexico, the largest onshore petroleum-producing basin in the United States. Approximately 1,300 reservoirs in the Permian Basin have been identified as having cumulative production greater than 1 MMbbl (1.59 x 10{sup 5} m{sup 3}) of oil through 2000. Of these significant-sized reservoirs, approximately 1,000 are in Texas and 300 in New Mexico. There are 32 geologic plays that have been defined for Permian Basin oil reservoirs, and each of the 1,300 major reservoirs was assigned to a play. The reservoirs were mapped and compiled in a Geographic Information System (GIS) by play. The final reservoir shapefile for each play contains the geographic location of each reservoir. Associated reservoir information within the linked data tables includes RRC reservoir number and district (Texas only), official field and reservoir name, year reservoir was discovered, depth to top of the reservoir, production in 2000, and cumulative production through 2000. Some tables also list subplays. Play boundaries were drawn for each play; the boundaries include areas where fields in that play occur but are smaller than 1 MMbbl (1.59 x 10{sup 5} m{sup 3}) of cumulative production. Oil production from the reservoirs in the Permian Basin having cumulative production of >1 MMbbl (1.59 x 10{sup 5} m{sup 3}) was 301.4 MMbbl (4.79 x 10{sup 7} m{sup 3}) in 2000. Cumulative Permian Basin production through 2000 was 28.9 Bbbl (4.59 x 10{sup 9} m{sup 3}). The top four plays in cumulative production are the Northwest Shelf San Andres Platform Carbonate play (3.97 Bbbl [6.31 x 10{sup 8} m{sup 3}]), the Leonard Restricted Platform Carbonate play (3.30 Bbbl [5.25 x 10{sup 8} m{sup 3}]), the Pennsylvanian and Lower Permian Horseshoe Atoll Carbonate play (2.70 Bbbl [4.29 x 10{sup 8} m{sup 3}]), and the San Andres Platform Carbonate play (2.15 Bbbl [3.42 x 10{sup 8} m{sup 3}]).

Existing research has consistently demonstrated poor compliance by health care workers with hand hygiene standards. This study examined the extent to which incorrect hand hygiene occurred as a result of the inability to easily distinguish between different hand hygiene solutions placed at washbasins. A direct observational method was used using ceiling-mounted, motion-activated video camera surveillance in a tertiary referral emergency department in Australia. Data from a 24-hour period on day 10 of the recordings were collected into the Hand Hygiene-Technique Observation Tool based on Feldman's criteria as modified by Larson and Lusk. A total of 459 episodes of hand hygiene were recorded by 6 video cameras in the 24-hour period. The observed overall rate of error in this study was 6.2% (27 episodes). In addition an overall rate of hesitation was 5.8% (26 episodes). There was no statistically significant difference in error rates with the 2 hand washbasin configurations. The amelioration of causes of error and hesitation by standardization of the appearance and relative positioning of hand hygiene solutions at washbasins may translate in to improved hand hygiene behaviors. Placement of moisturizer at the washbasin may not be essential. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

Dispersion relations in quantum electrodynamics on the noncommutative Minkowski space

We study field theories on the noncommutative Minkowski space with noncommuting time. The focus lies on dispersion relations in quantized interacting models in the Yang-Feldman formalism. In particular, we compute the two-point correlation function of the field strength in noncommutative quantum electrodynamics to second order. At this, we take into account the covariant coordinates that allow the construction of local gauge invariant quantities (observables). It turns out that this does not remove the well-known severe infrared problem, as one might have hoped. Instead, things become worse, since nonlocal divergences appear. We also show that these cancel in a supersymmetric version of the theory if the covariant coordinates are adjusted accordingly. Furthermore, we study the {phi}{sup 3} and the Wess-Zumino model and show that the distortion of the dispersion relations is moderate for parameters typical for the Higgs field. We also discuss the formulation of gauge theories on noncommutative spaces and study classical electrodynamics on the noncommutative Minkowski space using covariant coordinates. In particular, we compute the change of the speed of light due to nonlinear effects in the presence of a background field. Finally, we examine the so-called twist approach to quantum field theory on the noncommutative Minkowski space and point out some conceptual problems of this approach. (orig.)

Search for the Flavor Changing Neutral Current Decay t → Z q at √(s) = 1.96 TeV

This thesis reports the results of a search for the flavor changing neutral current decay of the top quark, t → Zq, in decays of t$\\bar{t}$ pairs produced in p$\\bar{p}$ collisions at a center-of-mass energy of 1.96 TeV. This search is performed on a data sample recorded by the Collider Detector at Fermilab (CDF), corresponding to an integrated luminosity of 1.9 fb^-1. This search follows a previous CDF analysis that resulted in an upper limit for the branching fraction β(t → Zq) of 10.4% at 95% C.L. using a dataset equivalent to 1.1 fb^-1 of integrated luminosity. This thesis extends to 1.9 fb^-1 of data, and has improved sensitivity to the small signal with the introduction of a template fit technique that includes systematic uncertainties by a linear interpolation between templates. Using a Feldman-Cousins construction, an upper limit at 95% C.L. is set on β(t → Zq) of 3.7%, with the expected upper limit in absence of a signal is 5.0 ± 2.2% for a top mass of 175 GeV/c².

Frameworks for Assessing Human Influence on Water Availability

2016-12-01

The water cycle is tightly coupled with water management and human water use behavior. Human activities and water use behavior can intensify the effects of a meteorological drought (a notion referred to as Anthropogenic Drought). In this presentation, we provide a general definition of anthropogenic drought. We then briefly review two different methods for assessing human influence on water availability: (1) a data-driven multivariate approach that links the information on inflow and surface reservoir storage to water demand; (2) A model-based framework that brings a top-down and bottom-up approach to provide localized water assessment based on local available infrastructure and projected water demands. Finally, we will show how the proposed methods can be used for water management scenario analysis (e.g., local water availability based on different human water demands scenarios). This presentation is primarily based on Mehran et al (Mehran A., Mazdiyasni O., AghaKouchak A., 2015, A Hybrid Framework for Assessing Socioeconomic Drought: Linking Climate Variability, Local Resilience, and Demand, Journal of Geophysical Research, 120 (15), 7520-7533, doi: 10.1002/2015JD023147.) and AghaKouchak et al (AghaKouchak A., Feldman D., Hoerling M., Huxman T., Lund J., 2015, Recognize Anthropogenic Drought, Nature, 524 (7566), 409-4011, doi:10.1038/524409a).

A new model of equilibrium subsurface hydration on Mars

Science.gov (United States)

Hecht, M. H.

2011-12-01

One of the surprises of the Odyssey mission was the discovery by the Gamma Ray Spectrometer (GRS) suite of large concentrations of water-equivalent hydrogen (WEH) in the shallow subsurface at low latitudes, consistent with 5-7% regolith water content by weight (Mitrofanov et al. Science 297, p. 78, 2002; Feldman et al. Science 297, p. 75, 2002). Water at low latitudes on Mars is generally believed to be sequestered in the form of hydrated minerals. Numerous attempts have been made to relate the global map of WEH to specific mineralogy. For example Feldman et al. (Geophys. Res. Lett., 31, L16702, 2004) associated an estimated 10% sulfate content of the soil with epsomite (51% water), hexahydrite (46% water) and kieserite (13% water). In such studies, stability maps have been created by assuming equilibration of the subsurface water vapor density with a global mean annual column mass vapor density. Here it is argued that this value significantly understates the subsurface humidity. Results from the Phoenix mission are used to suggest that the midday vapor pressure measured just above the surface is a better proxy for the saturation vapor pressure of subsurface hydrous minerals. The measured frostpoint at the Phoenix site was found to be equal to the surface temperature by night and the modeled temperature at the top of the ice table by day (Zent et al. J. Geophys. Res., 115, E00E14, 2010). It was proposed by Hecht (41st LPSC abstract #1533, 2010) that this phenomenon results from water vapor trapping at the coldest nearby surface. At night, the surface is colder than the surface of the ice table; by day it is warmer. Thus, at night, the subsurface is bounded by a fully saturated layer of cold water frost or adsorbed water at the surface, not by the dry boundary layer itself. This argument is not strongly dependent on the particular saturation vapor pressure (SVP) of ice or other subsurface material, only on the thickness of the dry layer. Specifically, the diurnal

Study of in vivo generators Pb-212/Bi--212 and U-230/Th-226 for alpha radioimmunotherapy

2011-01-01

Alpha-radioimmunotherapy is a promising cancer therapy that uses a-particles vectorized by monoclonal antibody to break down cancerous tumors. The notion of in vivo generator was introduced in 1989 by Leonard Mausner. The concept involves labeling of various molecular carriers (antibodies, peptides, etc) with intermediate half-life generator parents, which after accumulation in the desired tissue generate much shorter half-life daughter radionuclide. This thesis focuses on the study of two in vivo generators potentially interesting for alpha-radioimmunotherapy: Pb-212 / Bi-212 generator and U-230 / Th-226 generator. The first part of this work presents the Pb-212 / Bi-212 generator, two approaches allowing the vectorization. Chelation approach on a protein and an approach by encapsulation in liposomes have been proposed. This last approach appears to be the most interesting. In vitro stability studies have been performed on these labeling. The second part of this work presents the U-230 / Th-226 generator. Studies have first been made to achieve a theoretical model to describe the speciation of Th(IV) in human serum. The efficacy of DTPA as chelating agent for complexation of Th(IV) in human serum could thus be estimated. (author)

The ability to interpret vocal (prosodic) cues during social interactions can be disrupted by Parkinson's disease, with notable effects on how emotions are understood from speech. This study investigated whether PD patients who have emotional prosody deficits exhibit further difficulties decoding the attitude of a speaker from prosody. Vocally inflected but semantically nonsensical 'pseudo-utterances' were presented to listener groups with and without PD in two separate rating tasks. Task I required participants to rate how confident a speaker sounded from their voice and Task 2 required listeners to rate how polite the speaker sounded for a comparable set of pseudo-utterances. The results showed that PD patients were significantly less able than HC participants to use prosodic cues to differentiate intended levels of speaker confidence in speech, although the patients could accurately detect the politelimpolite attitude of the speaker from prosody in most cases. Our data suggest that many PD patients fail to use vocal cues to effectively infer a speaker's emotions as well as certain attitudes in speech such as confidence, consistent with the idea that the basal ganglia play a role in the meaningful processing of prosodic sequences in spoken language (Pell & Leonard, 2003).

SIALIDASE (NEURAMINIDASE) OF CORYNEBACTERIUM DIPHTHERIAE.

Warren, Leonard (National Institute of Arthritis and Metabolic Diseases, Bethesda, Md.) and C. W. Spearing. Sialidase (neuraminidase) of Corynebacterium diphtheriae. J. Bacteriol. 86:950-955. 1963.-The characteristics of a sialidase produced by Corynebacterium diphtheriae were studied. The enzyme was partially purified from preparations of diphtheria toxin on a column of Sephadex G-75. By this means the lethal factor of diphtheria toxin was separated, in part, from the sialidase activity. There appeared to be a close immunological relationship between the sialidases of C. diphtheriae and clostridia, since a preparation of diphtheria antitoxin was as effective an inhibitor of diphtheria sialidase as of the sialidase of three species of clostridia. Conversely, antitoxin to clostridia inhibited diphtheria sialidase. Diphtheria antitoxin was essentially inactive toward influenza virus sialidase, and was completely inactive against purified sialidase of Vibrio cholerae. Removal of sialic acid from the proteins in a preparation of diphtheria antitoxin did not alter the inhibitory activity of the antitoxin against diphtheria sialidase. The enzyme operated optimally at pH 5.5 and did not require calcium ions for activity. The substrate specificity of diphtheria sialidase appears to be the same as that of other previously described sialidases.

"Education for Values and Bioethics" is a project which aims to help the student to build his/her personal ethics. It was addressed to ninth grade students (mean age 14) who frequented public education in all schools of the City of Porto, Portugal-EU in 2010-2013 (N-1164). This research and action project intended to promote the acquisition of knowledge in the following areas: interpersonal relationships, human rights, responsible sexuality, health, environment and sustainable development, preservation of public property, culture, financial education, social innovation and ethical education for work. The students were asked to answer to a knowledge questionnaire on bioethics. To assess the values it was used Leonard Gordon's Survey of Personal Values and Survey of Interpersonal Values. The results of this study show that the project contributes to an increase of knowledge in the area of bioethics. Also the students enrolled in the program showed a development with regards the acquisition of the basic values of pluralistic societies. It is also suggested that this general knowledge on bioethics could be especially helpful to students that want a career in health sciences.

Leonard Susskind nous a enseigné la mécanique classique dans le premier volume de cette série, Le Minimum Théorique. Avec son co-auteur Art Friedman, il nous expose maintenant les bases théoriques et les concepts mathématiques associés au monde étrange de la physique quantique. Dans ce deuxième ouvrage, Susskind et Friedman proposent une introduction claire et vivante à ce domaine notoirement ardu et déroutant pour le néophyte. Ils nous font comprendre le comportement des objets sub-atomiques au travers d'abstractions mathématiques simples. A la différence de la plupart des ouvrages de vulgarisation – souvent mal à l'aise quant à la façon d'aborder les singularités de la mécanique quantique –, le livre embrasse cet univers dans sa totalité, y compris les paradoxes si contraires à notre logique. Susskind et Friedman proposent des explications limpides aux problématiques d'état quantique, d'incertitude, d'intrication quantique ou de représentation de l'état d'une particule. Accessib...

The flipped classroom module incorporates independent study in advance of in-class instructional sessions. It is unproven whether this methodology is effective within a medical school second-year organ system module. We report the development, implementation, and effectiveness of the flipped classroom methodology in a second-year medical student dermatology module at the University of Miami Leonard M. Miller School of Medicine. In a retrospective cohort analysis, we compared attitudinal survey data and mean scores for a 50-item multiple-choice final examination of the second-year medical students who participated in this 1-week flipped course with those of the previous year's traditional, lecture-based course. Each group comprised nearly 200 students. Students' age, sex, Medical College Admission Test scores, and undergraduate grade point averages were comparable between the flipped and traditional classroom students. The flipped module students' mean final examination score of 92.71% ± 5.03% was greater than that of the traditional module students' 90.92% ± 5.51% ( P flipped methodology to attending live lectures or watching previously recorded lectures. The flipped classroom can be an effective instructional methodology for a medical school second-year organ system module.

Lejaren A. Hiller, Jr.: A Memorial Tribute to a Chemist-Composer

Lejaren Hiller (1924-1994) was trained in chemistry but maintained a lifelong love of music. Like Alexander Borodin, the Russian chemist-composer, but eventually dedicated his career solely to music. His early work on the chemistry of polymers with Fred Wall at the University of Illinois introduced him to the Illiac computer, with which he did Monte Carlo calculations of polymer conformations. He promptly collaborated with Leonard Isaacson, a graduate student also associated with the Wall group, to teach the Illiac to compose music. Using a modified Monte Carlo technique to select the notes and other aspects of the music, they applied increasingly complex rules to define what constituted acceptable music. The result was their String Quartet #4, produced in 1957, often called the Illiac Suite. It is generally acknowledged as the first piece of music composed by a computer. Hiller remained a pioneer in the field of copmuter composition during his distinguished career at the University of Illinois and the State University of New York at Buffalo. This paper traces Hiller's careers in chemistry and music and examines the connections between the two.

The Unifying Strands: Formalism and Gestalt Theory in the Musical Philosophies of Aristoxenus, Descartes, and Meyer

Directory of Open Access Journals (Sweden)

Amanda N. Staufer

2018-03-01

Full Text Available In every age, philosophers deal with inquiries concerning musical meaning and the effect of music on the listener. Instead of answering the formidable question of musical meaning, this essay demonstrates the parallel aspects of three musical theories from ancient, Enlightenment, and modern times. Using the two criteria of musical formalism and Gestalt Theory, this essay systematically connects the philosophies of Aristoxenus of Tarentum, René Descartes, and Leonard Meyer. Musical formalism holds that music’s nature is innate, self-evident, able to be systematically deduced, and rational. According to formalism, musical meaning is defined by things objectively ‘there’ in the music, musical experience relies on cognition, and music is less a matter of sense than of mind. Gestalt Theory asserts that music is a unified totality—the whole gives meaning to the parts. This project demonstrates that three seemingly dissimilar musical philosophies include and prefigure the same foundational principles, although the theories reach different conclusions about musical meaning. In the research process, this essay utilizes documentary evidence. This essay concludes that the philosophies of Aristoxenus, Descartes, and Meyer are united by tendencies toward musical formalism and strands of the Gestalt view of music.

Report of the second Human Genome Diversity workshop

1992-12-31

The Second Human Genome Diversity Workshop was successfully held at Penn State University from October 29--31, 1992. The Workshop was essentially organized around 7 groups, each comprising approximately 10 participants, representing the sampling issues in different regions of the world. These groups worked independently, using a common format provided by the organizers; this was adjusted as needed by the individual groups. The Workshop began with a presentation of the mandate to the participants, and of the procedures to be followed during the workshop. Dr. Feldman presented a summary of the results from the First Workshop. He and the other organizers also presented brief comments giving their perspective on the objectives of the Second Workshop. Dr. Julia Bodmer discussed the study of European genetic diversity, especially in the context of the HLA experience there, and of plans to extend such studies in the coming years. She also discussed surveys of world HLA laboratories in regard to resources related to Human Genome Diversity. Dr. Mark Weiss discussed the relevance of nonhuman primate studies for understanding how demographic processes, such as mate exchange between local groups, affected the local dispersion of genetic variation. Primate population geneticists have some relevant experience in interpreting variation at this local level, in particular, with various DNA fingerprinting methods. This experience may be relevant to the Human Genome Diversity Project, in terms of practical and statistical issues.

Climate and history in the late 18th and early 19th centuries

Science.gov (United States)

Feldman, Theodore S.

As in many areas of human knowledge, the notion of climate acquired a deeper historical content around the turn of the 19th century. Natural philosophers, geographers, and others became increasingly aware of climate's own history and its relation to human, plant and animal, and Earth history. This article examines several aspects of this “historicization” of climate.The lively 18th century discussion of the influence of climate on society is well known. Montesquieu is its most famous representative, but Voltaire, Hume, Kant, and others also participated. Their debate was literary more than scientific, their goal the understanding of man, not climate. Partly for this reason and partly because of the lack of good information on climates, they made no attempt to gather substantial climatic data. In fact, the importance of systematically collecting reliable data was scarcely understood in any area of natural philosophy before the last decades of the century [Cf. Frängsmyr et al., 1990; Feldman, 1990]. Instead, participants in the debate repeated commonplaces dating from Aristotle and Hippocrates and based their conclusions on unreliable reports from travelers. As Glacken wrote of Montesquieu, “his dishes are from old and well-tested recipes” [Glacken, 1967, chapter 12]. This is not to say that the debate over climatic influence was not significant—only that its significance lay more in the history of man than in the atmospheric sciences.

An optimally weighted estimator of the linear power spectrum disentangling the growth of density perturbations across galaxy surveys

International Nuclear Information System (INIS)

Sorini, D.

2017-01-01

Measuring the clustering of galaxies from surveys allows us to estimate the power spectrum of matter density fluctuations, thus constraining cosmological models. This requires careful modelling of observational effects to avoid misinterpretation of data. In particular, signals coming from different distances encode information from different epochs. This is known as ''light-cone effect'' and is going to have a higher impact as upcoming galaxy surveys probe larger redshift ranges. Generalising the method by Feldman, Kaiser and Peacock (1994) [1], I define a minimum-variance estimator of the linear power spectrum at a fixed time, properly taking into account the light-cone effect. An analytic expression for the estimator is provided, and that is consistent with the findings of previous works in the literature. I test the method within the context of the Halofit model, assuming Planck 2014 cosmological parameters [2]. I show that the estimator presented recovers the fiducial linear power spectrum at present time within 5% accuracy up to k ∼ 0.80 h Mpc −1 and within 10% up to k ∼ 0.94 h Mpc −1 , well into the non-linear regime of the growth of density perturbations. As such, the method could be useful in the analysis of the data from future large-scale surveys, like Euclid.

Neutrinoless double beta decay is a phenomenon of fundamental interest in particle physics. The decay rates of double beta decay transitions to the excited states can provide input for Nuclear Transition Matrix Element calculations for the relevant two neutrino double beta decay process. It can be useful as supplementary information for the calculation of Nuclear Transition Matrix Element for the neutrinoless double beta decay process. In the present work, double beta decay of {sup 94}Zr to the 2{sup +}{sub 1} excited state of {sup 94}Mo at 871.1 keV is studied using a low background ∝ 230 cm{sup 3} HPGe detector. No evidence of this decay was found with a 232 g.y exposure of natural zirconium. The lower half-life limit obtained for the double beta decay of {sup 94}Zr to the 2{sup +}{sub 1} excited state of {sup 94}Mo is T{sub 1/2}(0ν + 2ν) > 3.4 x 10{sup 19} y at 90% C.L., an improvement by a factor of ∝ 4 over the existing experimental limit at 90% C.L. The sensitivity is estimated to be T{sub 1/2} (0ν + 2ν) > 2.0 x 10{sup 19} y at 90% C.L. using the Feldman-Cousins method. (orig.)

The genesis of unified gauge theories

Kibble, Tom

1993-01-01

The theoretical physics group at London's Imperial College in 1959 had three permanent faculty: Abdus Salam, his erstwhile thesis supervisor Paul Matthews, and John C.Taylor. I joined as a lecturer the following year. In those early days we had lots of visitors, both long- and short-term - Murray Gell-Mann, Ken Johnson, John Ward, Lowell Brown, Gordon Feldman and Steven Weinberg. About a year after I arrived we were transferred from the Mathematics to the Physics Department under the formidable Patrick (P.M.S.) Blackett. Having been brought up in the Cavendish Laboratory tradition under Lord Rutherford, Blackett was rather scornful of theoretical physicists, but he knew a good thing when he saw one and had persuaded Salam to join the rapidly expanding Physics Department. In 1960 field theory was widely regarded as very passé. It had had its triumphs: renormalization theory had made sense of divergences, and quantum electrodynamics had been magnificently vindicated. But field theory didn't seem to work for anything else, particularly not for the strong interactions, and was definitely out of fashion. There were, however, a few places in the world where field theory was still studied unashamedly. Imperial College was one. Harvard was certainly another; many of our visitors over the next few years were Julian Schwinger's students

Attachment as a mediator between community violence and posttraumatic stress symptoms among adolescents with a history of maltreatment.

Experiences that are detrimental to the attachment relationship, such as childhood maltreatment, may reduce feelings of safety among survivors and exacerbate the effects of exposure to subsequent violence, such as witnessing community violence. Though attachment style has been examined in regard to posttraumatic stress in adults who have a history of exposure to violence in childhood, less is known about the influence of attachment on the relationship between exposure to violence and posttraumatic stress symptoms in children and adolescents. The current study aimed to explore the role of attachment in the link between exposure to community violence and posttraumatic stress symptoms in adolescents with a history of childhood abuse. Participants included adolescents (aged 15-18 years) who had a history of maltreatment (N=75) and a matched sample without a childhood abuse history (N=78) from the National Data Archive on Child Abuse and Neglect (Salzinger, Feldman, & Ng-Mak, 2008). A conditional process model using bootstrapping to estimate indirect effects showed a significant indirect effect of insecure attachment on the relationship between exposure to community violence and posttraumatic stress symptoms for adolescents with a history of childhood physical abuse, but not for adolescents without this history. Implications for a cumulative risk model for post-trauma pathology starting in adolescence are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

On the unitary transformation between non-quasifree and quasifree state spaces and its application to quantum field theory on curved spacetimes

International Nuclear Information System (INIS)

Gottschalk, Hanno; Hack, Thomas-Paul

2009-12-01

Using *-calculus on the dual of the Borchers-Uhlmann algebra endowed with a combinatorial co-product, we develop a method to calculate a unitary transformation relating the GNS representations of a non-quasifree and a quasifree state of the free hermitian scalar field. The motivation for such an analysis and a further result is the fact that a unitary transformation of this kind arises naturally in scattering theory on non-stationary backgrounds. Indeed, employing the perturbation theory of the Yang-Feldman equations with a free CCR field in a quasifree state as an initial condition and making use of extended Feynman graphs, we are able to calculate the Wightman functions of the interacting and outgoing fields in a φ p -theory on arbitrary curved spacetimes. A further examination then reveals two major features of the aforementioned theory: firstly, the interacting Wightman functions fulfil the basic axioms of hermiticity, invariance, spectrality (on stationary spacetimes), perturbative positivity, and locality. Secondly, the outgoing field is free and fulfils the CCR, but is in general not in a quasifree state in the case of a non-stationary spacetime. In order to obtain a sensible particle picture for the outgoing field and, hence, a description of the scattering process in terms of particles (in asymptotically flat spacetimes), it is thus necessary to compute a unitary transformation of the abovementioned type.

In order to obtain a sensible particle picture for the outgoing field and, hence, a description of the scattering process in terms of particles (in asymptotically flat spacetimes), it is thus necessary to compute a unitary transformation of the abovementioned type.

The genesis of unified gauge theories

Energy Technology Data Exchange (ETDEWEB)

Kibble, Tom

1993-06-15

The theoretical physics group at London's Imperial College in 1959 had three permanent faculty: Abdus Salam, his erstwhile thesis supervisor Paul Matthews, and John C.Taylor. I joined as a lecturer the following year. In those early days we had lots of visitors, both long- and short-term - Murray Gell-Mann, Ken Johnson, John Ward, Lowell Brown, Gordon Feldman and Steven Weinberg. About a year after I arrived we were transferred from the Mathematics to the Physics Department under the formidable Patrick (P.M.S.) Blackett. Having been brought up in the Cavendish Laboratory tradition under Lord Rutherford, Blackett was rather scornful of theoretical physicists, but he knew a good thing when he saw one and had persuaded Salam to join the rapidly expanding Physics Department. In 1960 field theory was widely regarded as very passé. It had had its triumphs: renormalization theory had made sense of divergences, and quantum electrodynamics had been magnificently vindicated. But field theory didn't seem to work for anything else, particularly not for the strong interactions, and was definitely out of fashion. There were, however, a few places in the world where field theory was still studied unashamedly. Imperial College was one. Harvard was certainly another; many of our visitors over the next few years were Julian Schwinger's students.

On a third S-matrix in the theory of quantized fields on curved spacetimes

International Nuclear Information System (INIS)

Gottschalk, H.; Hack, T.

2007-01-01

Wightman functions for interacting quantum fields on curved space times are calculated via the perturbation theory of the Yang-Feldman equations, where the incoming field is a free field in a quasifree representation. We show that these Wightman functions that are obtained as a sum over extended Feynman graphs fulfill the basic axioms of hermiticity, invariance, spectrality (on stationary spacetimes), perturbative positivity and locality (the latter property is shown up to second order in the loop expansion). In the case of non-stationary spacetimes, the outgoing field in general is in a non-quasifree representation of the CCR. This makes it necessary to develop a method to calculate the unitary transformation between a non quasifree representation and a quasifree one. This is carried out using *-calculus on the dual of the Borchers algebra with a combinatorial co-product. Given that preferred quasifree representations for early and late times exist, we thus obtain a complete scattering description using three S-matrices: The first is determined by vacuum expectation values between incoming and outgoing fields. The second is a unitary transformation between the non-quasifree representation for the ''out''-fields and the quasifree representation for the ''in''-field. The last one is the Bogoliubov transformation between the preferred representation at early times (i.e. the ''in''-field representation) and the preferred representation at late times. (orig.)

Full Text Available Measuring of estradiol level in the peripheral blood in dog is important for the precise estrus detection. In proestrus, estradiol dominates. In estrus, however, estradiol progressively decreases while progesterone and LH increase, the latter shortly and abruptly. The research of Feldman and Nelson (7 indicates that the beginning of the sexual cycle of the female dog is the result of complex interaction of the environment, general health condition, condition of the ovaries, condition of the uterus, animal age, and some unidentified factors. Estradiol level in the peripheral circulation is starting to rise before the beginning of the proestrus, and during the proestrus the female dog is under the influence of estradiol (4. Our research included 30 female dogs on the territory of Tuzla Municipality, in the springtime. The female dogs were divided in three groups according to the breeding and living conditions: group A (female dogs living in the house environment; group B (female dogs living in the shelter; group C (female stray dogs. For the researched groups, estradiol level varied between 6,265 pg\\ml and 69,734 pg\\ml over the springtime. Of importance is the results can be applied in the evaluation of estrus in the female dogs, and when considering factors crucial for their sustainable reproduction potential.Key words: dogs, estradiol, spring

Educating science teachers for sustainability: questions, contradictions and possibilities for rethinking learning and pedagogy

Rahm, Jrène; Gorges, Anna

2017-09-01

In this review, we explore what educating science teachers for sustainability implies according to the 23 book chapters and many sampled teacher education and science methods courses in the edited book by Susan Stratton, Rita Hagevick, Allan Feldman and Mark Bloom, entitled Educating Science Teachers for Sustainability, published in 2015 by Springer as part of the ASTE Series in Science Education. We situate the review in the current complex landscape of discourses around sustainability education, exploring its grounding in an anthropocentric ideology next to emancipatory practices and a holistic vision of the world. We offer a quick overview of the chapters and themes addressed. We then take up some ideas to think with. We are particularly invested in thinking about the implications of sustainability education as going beyond science teachers and science education, and as implying a serious engagement with and critique of current unsustainable ways of living. We play with the idea of taking sustainability education beyond neoliberal ideals of education and offer some suggestions by bringing in voices of students, youth, land-based learning and the idea of living sustainability. We also explore what indigenous scholars and epistemologies could have contributed to an exploration of sustainability education, a voice that was absent in the book, yet helps desettle the conversation and actions taken, moving the discourse beyond an Eurocentric grounding.

Feldman, Sue S

2018-04-30

The primary value relative to health information exchange has been seen in terms of cost savings relative to laboratory and radiology testing, emergency department expenditures, and admissions. However, models are needed to statistically quantify value and sustainability and better understand the dependent and mediating factors that contribute to value and sustainability. The purpose of this study was to provide a basis for early model development for health information exchange value and sustainability. A qualitative study was conducted with 21 interviews of eHealth Exchange participants across 10 organizations. Using a grounded theory approach and 3.0 as a relative frequency threshold, 5 main categories and 16 subcategories emerged. This study identifies 3 core current perceived value factors and 5 potential perceived value factors-how interviewees predict health information exchanges may evolve as there are more participants. These value factors were used as the foundation for early model development for sustainability of health information exchange. Using the value factors from the interviews, the study provides the basis for early model development for health information exchange value and sustainability. This basis includes factors from the research: fostering consumer engagement; establishing a provider directory; quantifying use, cost, and clinical outcomes; ensuring data integrity through patient matching; and increasing awareness, usefulness, interoperability, and sustainability of eHealth Exchange. ©Sue S Feldman.

Lyman Alpha Camera for Io's SO2 atmosphere and Europa's water plumes

McEwen, Alfred S.; Sandel, Bill; Schneider, Nick

2014-05-01

The Student Lyman-Alpha Mapper (SLAM) was conceived for the Io Volcano Observer (IVO) mission proposal (McEwen et al., 2014) to determine the spatial and temporal variations in Io's SO2 atmosphere by recording the H Ly-α reflection over the disk (Feldman et al., 2000; Feaga et al., 2009). SO2 absorbs at H Ly-α, thereby modulating the brightness of sunlight reflected by the surface, and measures the density of the SO2 atmosphere and its variability with volcanic activity and time of day. Recently, enhancements at the Ly-α wavelength (121.57 nm) were seen near the limb of Europa and interpreted as active water plumes ~200 km high (Roth et al., 2014). We have a preliminary design for a very simple camera to image in a single bandpass at Ly-α, analogous to a simplified version of IMAGE EUV (Sandel et al. 2000). Our goal is at least 50 resolution elements across Io and/or Europa (~75 km/pixel), ~3x better than HST STIS, to be acquired at a range where the radiation noise is below 1E-4 hits/pixel/s. This goal is achieved with a Cassegrain-like telescope with a 10-cm aperture. The wavelength selection is achieved using a simple self-filtering mirror in combination with a solar-blind photocathode. A photon-counting detector based on a sealed image intensifier preserves the poisson statistics of the incoming photon flux. The intensifier window is coated with a solar-blind photocathode material (CsI). The location of each photon event is recorded by a position-sensitive anode based on crossed delay-line or wedge-and-strip technology. The sensitivity is 0.01 counts/pixel/sec/R, sufficient to estimate SO2 column abundances ranging from 1E15 to 1E17 per cm2 in a 5 min (300 sec) exposure. Sensitivity requirements to search for and image Europa plumes may be similar. Io's Ly-α brightness of ~3 kR exceeds the 0.8 kR brightness of Europa's plume reported by Roth et al. (2014), but the plume brightness is a direct measurement rather than inferring column abundance from

'New legislation in Queensland has provided a "pathway" for the privatisation of health assets and services in Queensland, which effectively realigns the health care system to the financial market. This column explores how this legislation contained the antecedents of the Queensland doctors' dispute when doctors roundly rejected new employment contracts in February 2014. It also argues that such legislation and its attendant backlash provides a valuable case study in view of the federal government's 2014 budget offer to the States of extra funding if they sell their health assets to fund new infrastructure. The move to privatise health in Queensland has also resulted in a government assault on the ethical credibility of the opposing medical profession and changes to the health complaints system with the introduction of a Health Ombudsman under ministerial control. The column examines these changes in light of R (Heather) v Leonard Cheshire Foundation [2001] EWHC Admin 429, a case concerning the obligations of a private entity towards publically funded clients in the United Kingdom. In discussing concerns about the impact of privatisation on the medical profession, the column points to a stark conflict between the duty to operate hospitals as a business rather than as a duty to patients.

Czy filozof powinien bać się Stephena Hawkinga?

Full Text Available Scientists, who have made significant contributions to the deepening of knowledge in their area of research, often engage in discussions concerning the ultimate explanations of the Universe. This is particularly visible in cosmology for the theories presented directly refer to the major questions raised by the philosophers such as the origin and the fate of the Universe, the nature of the physical laws and the existence of God. Stephen Hawking has made himself known as one of the most vocal speakers in this regard by insisting that the no-boundary Hartle-Hawking model can be used to explain away the need for any external agent in the creation of the Universe. In his recent popular book entitled The Grand Design written together with Leonard Mlodinow, Hawking declared the death of philosophy on the grounds that it did not stood up to the challenges of science by not answering the ultimate questions the way science is now capable of doing. The article aims at demonstrating that Hawking’s and Mlodinow’s radical claims rest on very strong and ill-justified philosophical assumptions of the model dependent realism. Although it is a philosophically legitimate standpoint, its reductive character does not permit the extent of generalization as suggested in The Grand Design.

Originally discovered by Leonard da Vinci in the 15th century, the force of friction is directly proportional to the applied load (known as Amontons' first law of friction). Furthermore, kinetic friction is independent of the sliding speed (known as Coulomb's law of friction). These empirical laws break down at high normal pressure (due to plastic deformation) and low sliding speed (in the transition regime between static friction and kinetic friction). An important example of this phenomenon is friction between the asperities of tectonic plates on the Earth. Despite its significance, little is known about the detailed mechanism of friction in this regime due to the lack of experimental methods. Here we demonstrate in situ time-lapse nanoscopy of friction between asperities sliding at ultralow speed (∼0.01 nm/s) under high normal pressure (∼GPa). This is made possible by compressing and rubbing a pair of nanometer-scale crystalline silicon anvils with electrostatic microactuators and monitoring its dynamical evolution with a transmission electron microscope. Our analysis of the time-lapse movie indicates that superplastic behavior is induced by decrystallization, plastic deformation, and atomic diffusion at the asperity-asperity interface. The results hold great promise for a better understanding of quasi-static friction under high pressure for geoscience, materials science, and nanotechnology.

Full Text Available In this paper the influence of types of interlayer interactions on the elastic modules of multilayer graphene sheets (GS and nanocomposites is studied. The modeling and investigation of mechanical properties of graphite layers are performed using molecular mechanics (MM method. Initially, due to improving the model and decreasing the amount of computations, three types of elements such as beam, linear spring and nonlinear spring are used. To continue, the mechanical properties of multilayers and nanocomposites are compared using three types of interlayer interactions. Initially, nonlinear spring defined by Leonard Jones potential is used to define interlayer interactions (ordinary case. To continue, linear spring with certain stiffness, to obtain an equal linear spring and also to investigate the ultimate capacity of interlayer interactions in the force translation, by increasing the stiffness of linear springs, is employed (chemical change. Then once by omitting all Van der Waals interactions and defects creation in graphite layers, they are devoted to create covalent interlayer interactions (using Morse potential and another time, Van der Waals and covalent interlayer interactions are created spontaneously to study the properties of multilayers and nanocomposites (functionalization. The results are compared with other available literatures in this case to validate the modeling.

Crofelemer is a first-in-class antidiarrheal agent that is United States Food and Drug Administration approved for noninfectious diarrhea in persons with HIV on antiretroviral therapy. Crofelemer is derived from the blood-red sap of Croton lechleri, a South American plant whose latex is associated with various healing attributes. In fact, it has a unique effect on chloride channels in the gastrointestinal lumen, and leads to decreased efflux of sodium molecules and water, thereby decreasing the frequency of stools. Crofelemer – a plant-based compound, discovered and investigated as the result of the increased prevalence of ethnobotany – is a novel and effective agent with a good safety profile. It could potentially improve the quality of life for HIV-infected patients and hopefully, in turn, will improve antiretroviral therapy compliance.Keywords: chloride channels, secretory diarrhea, botanical, sangre de grado, intra-luminal

Subgrid-scale turbulence in shock-boundary layer flows

2015-04-01

Data generated by direct numerical simulation (DNS) for a Mach 2.75 zero-pressure gradient turbulent boundary layer interacting with shocks of different intensities are used for a priori analysis of subgrid-scale (SGS) turbulence and various terms in the compressible filtered Navier-Stokes equations. The numerical method used for DNS is based on a hybrid scheme that uses a non-dissipative central scheme in the shock-free turbulent regions and a robust monotonicity-preserving scheme in the shock regions. The behavior of SGS stresses and their components, namely Leonard, Cross and Reynolds components, is examined in various regions of the flow for different shock intensities and filter widths. The backscatter in various regions of the flow is found to be significant only instantaneously, while the ensemble-averaged statistics indicate no significant backscatter. The budgets for the SGS kinetic energy equation are examined for a better understanding of shock-tubulence interactions at the subgrid level and also with the aim of providing useful information for one-equation LES models. A term-by-term analysis of SGS terms in the filtered total energy equation indicate that while each term in this equation is significant by itself, the net contribution by all of them is relatively small. This observation is consistent with our a posteriori analysis.

Purpose: To provide historical background on the development and initial studies of the gynecological (gyn) applicators developed by Dr. Gilbert H. Fletcher, a radiation oncologist and chairperson from 1948 to 1981 of the department at the M.D. Anderson Hospital (MDAH) for Cancer Research in Houston, TX, and to acknowledge the previously unrecognized contribution that Dr. Leonard G. Grimmett, a radiation physicist and chairperson from 1949 to 1951 of the physics department at MDAH, made to the development of the gynecological applicators. Methods and Materials: We reviewed archival materials from the Historical Resource Center and from the Department of Radiation Physics at University of Texas M. D. Anderson Cancer Center, as well as contemporary published papers, to trace the history of the applicators. Conclusions: Dr. Fletcher’s work was influenced by the work on gynecologic applicators in the 1940s in Europe, especially work done at the Royal Cancer Hospital in London. Those efforts influenced not only Dr. Fletcher’s approach to the design of the applicators but also the methods used to perform in vivo measurements and determine the dose distribution. Much of the initial development of the dosimetry techniques and measurements at MDAH were carried out by Dr. Grimmett.

A positive attitude toward medication reported by patients was significantly associated with greater clinical improvement on the Positive and Negative Syndrome Scale and lower discontinuation rates. These results suggest that patients’ perceptions of treatment benefits are associated with objective clinical measures, including reduction of symptom severity and lower discontinuation rates. Furthermore, olanzapine may be associated with more positive treatment attitudes. These findings may contribute to a better understanding of reasons for treatment adherence from patients’ own perspectives.Keywords: antipsychotic agents, medication adherence, patient satisfaction, schizophrenia, treatment efficacy

An Organizational Perspective to the Creation of the Research Field.

2016-09-01

The aim of the paper is to contribute to the definition and analysis of the "access to the field" (Feldman et al. 2003) through an inter-organizational perspective. The paper discusses a case study on the access of a researcher to a hospital department where both organizations and actors are shown as actively constructing the research site. Both researcher and participants are described in terms of work organizations originally engaged in parallel systems of activity. Dynamics of negotiation "tied" the different actors' activities in a new activity system where researcher and participants concur to the effectiveness of both organizations (i.e., the research and the hospital ward). An Activity Theory perspective (Leont'ev 1978) is used with the aim of focusing the analysis on the activities in charge to the different actors. The approach adopted introduces the idea that, from the outset, research is made possible by a process of co-construction that works through the development of a completely new and shared work space arising around the encounter between researchers and participants. It is the balance between improvised actions and the co-creation of "boundary objects" (Star and Griesemer 1989), which makes interlacement possible between the two activity systems. The concept of "knotworking" (Engeström 2007a) is adopted to interpret specific actions by both organizations and actors intended to build a knot of activities whereby the new research system takes place.

This thesis describes a search for the rare decay K L → π 0 π 0 γ using data from the KTeV experiment, using the topology K L → π 0 π D 0 γ (where π D 0 → γe + e - ). Due to Bose statistics and the real nature of the photon, the K L → π 0 π 0 γ decay can proceed at lowest order only by the Cp conserving direct emission of an E2 photon. The decay vanishes to O(p 4 ) in chiral perturbation theory and is a probe of the theory to the sixth order. The primary background to this decay consists of K L → π 0 π 0 π D 0 events with one lost photon. The upper limit for the decay K L → π 0 π 0 γ presented in this thesis is 2.32 x 10 -7 at the 90% confidence level. This upper limit was derived from both 1997 and 1999 data, using a blind analysis. The upper limit was derived from a Feldman-Cousins method, based on a weighted total of 0.53 data events in the signal region with an expected K L → π 0 π 0 π D 0 background of 0.37 ± 0.28 events. The previous upper limit for this decay was 5.6 x 10 -6 at the 90% confidence level

Research purpose: The purpose of this study was to investigate intention to quit amongst Generation Y academics in HEIs. Motivation for the study: Higher education institutions are more dependent on the abilities and commitment of their staff than most other organisations. More than 4000 academics will retire and need to be replaced by 2018, providing justification for the study of intention to quit of academics. Research design, approach and method: An ex post facto quantitative research design was followed. Academics at six HEIs in South Africa were sampled. Measurement instruments included abridged versions of the Utrecht Work Engagement Scale, Multifactor Leadership Questionnaire, Arnold and Feldman Intention to Quit Scale, Job Descriptive Scale and Chew’s reward scale. Main findings: Employee engagement, job satisfaction, remuneration, reward, recognition and transformational leadership were significantly related to intention to quit. In the partial model, three of these variables explained 45% of the variance in intention to quit. Partial least square path modelling revealed that employee engagement and job satisfaction have significant negative impacts on intention to quit. Practical/managerial implications: The findings serve as input for the development of efficacious strategies to retain Generation Y academics at HEIs in South Africa. Contribution/value-add: This study contributes to our knowledge of intention to quit amongst Generation Y academics. It provides evidence of the complexity and inter-relatedness of variables in the phenomenological network of intention to quit.

Additionally, multiple comorbidities exist, including cardiovascular, metabolic, and psychiatric. The chronic nature of psoriasis is often frustrating for both patients and physicians alike. Many options for treatment exist, though successful disease management rests largely on patients through the application of topical corticosteroids, Vitamin D analogs, and calcineurin inhibitors, amongst others and the administration of systemic medications such as biologics and methotrexate. Phototherapy is another option that also requires active participation from the patient. Many barriers to effective self-management of psoriasis exist. Successful treatment requires the establishment of a strong doctor-patient relationship and patient empowerment in order to maximize adherence to a treatment regimen and improve outcomes. Improving patient adherence to treatment is necessary in effective self-management. Many tools exist to educate and empower patients, including online sources such as the National Psoriasis Foundation and online support group, Talk Psoriasis, amongst others. Effective self management is critical in decreasing the physical burden of psoriasis and mitigating its multiple physical, psychological, and social comorbidities, which include obesity, cardiovascular disease, alcohol dependence, depression, anxiety, and social anxiety.

Despite the availability of effective interventions, most individuals with social anxiety disorder do not seek treatment. Given their fear of negative evaluation, socially anxious individuals might be especially susceptible to stigma concerns, a recognized barrier for mental health treatment. However, very little is known about the stigma specific to social anxiety disorder. In a design similar to Feldman and Crandall (2007), university undergraduate students read vignettes about target individuals with a generic mental illness label, major depressive disorder, and social anxiety disorder. Subjects rated each of 3 people in the vignettes on social distance and 17 dimensions including dangerousness, heritability and prevalence of the disorder, and gender ratio. Results indicated that being male and not having experience with mental health treatment was associated with somewhat greater preferred social distance. Multiple regression analyses revealed that being embarrassed by the disorder and dangerousness predicted social distance across all 3 vignettes. The vignette for social anxiety disorder had the most complex model and included work impairment, more common among women, and more avoidable. These results have implications for understanding the specific aspects of the stigma associated with social anxiety disorder. Public service messages to reduce stigma should focus on more accurate information about dangerousness and mental illness, given this is an established aspect of mental illness stigma. More nuanced messages about social anxiety might be best incorporated into the treatment referral process and as part of treatment. (c) 2015 APA, all rights reserved).

In a previous paper wave propagation was studied according to a sixth-order partial differential equation involving a complex mass M. The corresponding Yang-Feldman integral equations (indicated as SM-YF-equations), were formulated using modified Green's functions Gsub(R)sup(M)(x) and Gsub(A)sup(M)(x), which then incorporate the partial differential equation together with certain boundary conditions. In this paper certain limit properties of these modified Green's functions are derived: (a) It is shown that for mod(M)→infinity the Green's functions Gsub(R)sup(M)(x) and Gsub(A)sup(M)(x) approach the Green's functions Δsub(R)(x) and Δsub(A)(x) of the corresponding KG-equation (Klein-Gordon equation). (b) It is further shown that the asymptotic behaviour of Gsub(R)sup(M)(x) and Gsub(A)sup(M)(x) is the same as of Δsub(R)(x) and Δsub(A)(x)-and also the same as for Dsub(R)(x) and Dsub(A)(x) for t→+-infinity;, where Dsub(R) and Dsub(A) are the Green's functions for the KG-equation with mass zero. It is essential to take limits in the sense of distribution theory in both cases (a) and (b). The property (b) indicates that the wave propagation properties of the SM-YF-equations, the KG-equation with finite mass and the KG-equation with mass zero are closely related in an asymptotic sense.

Health informatics research has traditionally been dominated by experimental and quasi-experimental designs. An emerging area of study in organisational sociology is routinisation (how collaborative work practices become business-as-usual). There is growing interest in the use of ethnography and other in-depth qualitative approaches to explore how collaborative work routines are enacted and develop over time, and how electronic patient records (EPRs) are used to support collaborative work practices within organisations. Following Feldman and Pentland, we will use 'the organisational routine' as our unit of analysis. In a sample of four UK general practices, we will collect narratives, ethnographic observations, multi-modal (video and screen capture) data, documents and other artefacts, and analyse these to map and compare the different understandings and enactments of three common routines (repeat prescribing, coding and summarising, and chronic disease surveillance) which span clinical and administrative spaces and which, though 'mundane', have an important bearing on quality and safety of care. In a detailed qualitative analysis informed by sociological theory, we aim to generate insights about how complex collaborative work is achieved through the process of routinisation in healthcare organisations. Our study offers the potential not only to identify potential quality failures (poor performance, errors, failures of coordination) in collaborative work routines but also to reveal the hidden work and workarounds by front-line staff which bridge the model-reality gap in EPR technologies and via which "automated" safety features have an impact in practice.

The Swedish Zero Power Reactor R0

1961-05-15

The reactor R0 is a critical facility built for heavy water and natural uranium or fuel of low enrichment,, The first criticality was achieved September 25, 1959. During a first period of more than two years the R0 will be operated as a bare reactor in order to simplify interpretation of results. The reactor tank is 3. 2 m high and 2. 25 m in diameter. The fuel suspension system is quite flexible in order to facilitate fuel exchange and lattice variations. The temperature of the water can be varied between about 10 and 90 C by means of a heater and a cooler placed in the external circulating system. The instrumentation of the reactor has to meet the safety requirements not only during operation but also during rearrangements of the core in the shut-down state. Therefore, the shut-down state is always defined by a certain low 'safe' moderator level in the reactor tank. A number of safety rods are normally kept above the moderator ready for action. For manual or automatic control of the reactor power a specially designed piston pump is needed, by which the moderator level is varied. The pump speed is controlled from the reactor power error by means of a Ward-Leonard system. Moderator level measurement is made by means of a water gauge with an accuracy of {+-} 0. 1 mm.

One key question in neurolinguistics is the extent to which the neural processing system for language requires linguistic experience during early life to develop fully. We conducted a longitudinal anatomically constrained magnetoencephalography (aMEG) analysis of lexico-semantic processing in 2 deaf adolescents who had no sustained language input until 14 years of age, when they became fully immersed in American Sign Language. After 2 to 3 years of language, the adolescents' neural responses to signed words were highly atypical, localizing mainly to right dorsal frontoparietal regions and often responding more strongly to semantically primed words (Ferjan Ramirez N, Leonard MK, Torres C, Hatrak M, Halgren E, Mayberry RI. 2014. Neural language processing in adolescent first-language learners. Cereb Cortex. 24 (10): 2772-2783). Here, we show that after an additional 15 months of language experience, the adolescents' neural responses remained atypical in terms of polarity. While their responses to less familiar signed words still showed atypical localization patterns, the localization of responses to highly familiar signed words became more concentrated in the left perisylvian language network. Our findings suggest that the timing of language experience affects the organization of neural language processing; however, even in adolescence, language representation in the human brain continues to evolve with experience. © The Author 2014.

On January 12, 1975, a rock seemed to fall from the sky over New York State’s Schoharie County hitting the tractor of a local farmer, who was “preparing his fields for spring planting.” As the farmer later described the event to a reporter from the UFO INVESTIGATOR, the object glanced off the tractor, fell to the ground, and melted its way through a patch of ice that was two and one half inches thick. The farmer, Leonard Tillapaugh, called the county sheriff, Harvey Stoddard, who recovered the rock, noting that it “was still warm.” Why and how a sample of the rock came to Los Alamos is not known. However, it captivated a wide Laboratory audience, was subjected to rigorous testing and evaluation. Los Alamos used the scientific method in the manner promoted by Hynek. Did Los Alamos solve the mystery of the rock’s origin? Not definitively. Although the exact origin could not be determined, it was shown conclusively that the rock was not from outer space. With that said, the saga of Rock that hit New York came to an end. Nothing more was said or written about it. The principals involved have long since passed from the scene. The NICAP ceased operations in 1980. And, the rock, itself, has disappeared.

Full Text Available Brent S Sorenson, Kaysie L Banton, Lance B Augustin, Arnold S Leonard, Daniel A SaltzmanDepartment of Surgery, University of Minnesota Medical School, Minneapolis, MN, USAAbstract: Fruit seeds high in antioxidants have been shown to have anticancer properties and enhance host protection against microbial infection. Recently we showed that a single oral dose of Salmonella enterica serovar Typhimurium expressing a truncated human interleukin-2 gene (SalpIL2 is avirulent, immunogenic, and reduces hepatic metastases through increased natural killer cell populations in mice. To determine whether antioxidant compounds enhance the antitumor effect seen in SalpIL2-treated animals, we assayed black cumin (BC, black raspberry (BR, and milk thistle (MT seed oils for the ability to reduce experimental hepatic metastases in mice. In animals without tumor, BC and BR oil diets altered the kinetics of the splenic lymphocyte response to SalpIL2. Consistent with previous reports, BR and BC seed oils demonstrated independent antitumor properties and moderate adjuvant potential with SalpIL2. MT oil, however, inhibited the efficacy of SalpIL2 in our model. Based on these data, we conclude that a diet high in antioxidant oils promoted a more robust immune response to SalpIL2, thus enhancing its antitumor efficacy.Keywords: antioxidants, colorectal cancer, tumor models, metastasis

From Hayflick to Walford: the role of T cell replicative senescence in human aging.

Science.gov (United States)

Effros, Rita B

2004-06-01

The immunologic theory of aging, proposed more than 40 years ago by Roy Walford, suggests that the normal process of aging in man and in animals is pathogenetically related to faulty immunological processes. Since that time, research on immunological aging has undergone extraordinary expansion, leading to new information in areas spanning from molecular biology and cell signaling to large-scale clinical studies. Investigation in this area has also provided unexpected insights into HIV disease, many aspects of which represent accelerated immunological aging. This article describes the initial insights and vision of Roy Walford into one particular facet of human immunological aging, namely, the potential relevance of the well-studied human fibroblast replicative senescence model, initially developed by Leonard Hayflick, to cells of the immune system. Extensive research on T cell senescence in cell culture has now documented changes in vitro that closely mirror alterations occurring during in vivo aging in humans, underscoring the biological significance of T cell replicative senescence. Moreover, the inclusion of high proportions of putatively senescent T cells in the 'immune risk phenotype' that is associated with early mortality in octogenarians provides initial clinical confirmation of both the immunologic theory of aging and the role of the T cell Hayflick Limit in human aging, two areas of gerontological research pioneered by Roy Walford.

Classification of underwater targets from autonomous underwater vehicle sampled bistatic acoustic scattered fields.

Fischell, Erin M; Schmidt, Henrik

2015-12-01

One of the long term goals of autonomous underwater vehicle (AUV) minehunting is to have multiple inexpensive AUVs in a harbor autonomously classify hazards. Existing acoustic methods for target classification using AUV-based sensing, such as sidescan and synthetic aperture sonar, require an expensive payload on each outfitted vehicle and post-processing and/or image interpretation. A vehicle payload and machine learning classification methodology using bistatic angle dependence of target scattering amplitudes between a fixed acoustic source and target has been developed for onboard, fully autonomous classification with lower cost-per-vehicle. To achieve the high-quality, densely sampled three-dimensional (3D) bistatic scattering data required by this research, vehicle sampling behaviors and an acoustic payload for precision timed data acquisition with a 16 element nose array were demonstrated. 3D bistatic scattered field data were collected by an AUV around spherical and cylindrical targets insonified by a 7-9 kHz fixed source. The collected data were compared to simulated scattering models. Classification and confidence estimation were shown for the sphere versus cylinder case on the resulting real and simulated bistatic amplitude data. The final models were used for classification of simulated targets in real time in the LAMSS MOOS-IvP simulation package [M. Benjamin, H. Schmidt, P. Newman, and J. Leonard, J. Field Rob. 27, 834-875 (2010)].

Spatial Learning: Conditions and Basic Effects

Directory of Open Access Journals (Sweden)

Victoria D. Chamizo

2002-01-01

Full Text Available A growing body of evidence suggests that the spatial and the temporal domains seem to share the same or similar conditions, basic effects, and mechanisms. The blocking, unblocking and overshadowing experiments (and also those of latent inhibition and perceptual learning reviewed by Prados and Redhead in this issue show that to exclude associative learning as a basic mechanism responsible for spatial learning is quite inappropriate. All these results, especially those obtained with strictly spatial tasks, seem inconsistent with O’Keefe and Nadel’s account of true spatial learning or locale learning. Their theory claims that this kind of learning is fundamentally different and develops with total independence from other ways of learning (like classical and instrumental conditioning -taxon learning. In fact, the results reviewed can be explained appealing on to a sophisticated guidance system, like for example the one proposed by Leonard and McNaughton (1990; see also McNaughton and cols, 1996. Such a system would allow that an animal generates new space information: given the distance and address from of A to B and from A to C, being able to infer the distance and the address from B to C, even when C is invisible from B (see Chapuis and Varlet, 1987 -the contribution by McLaren in this issue constitutes a good example of a sophisticated guidance system.

The old pillars of new retailing.

Science.gov (United States)

Berry, L L

2001-04-01

Despite the harsh realities of retailing, the illusion persists that magical tools can help companies overcome the problems of fickle consumers, price-slashing competitors, and mood swings in the economy. Such wishful thinking holds that retailers will thrive if only they communicate better with customers through e-mail, employ hidden cameras to learn how customers make purchase decisions, and analyze scanner data to tailor special offers and manage inventory. But the truth is, there are no quick fixes. In the course of his extensive research on dozens of retailers, Leonard Berry found that the best companies create value for their customers in five interlocking ways. Whether you're running a physical store, a catalog business, an e-commerce site, or a combination of the three, you have to offer your customers superior solutions to their needs, treat them with respect, and connect with them on an emotional level. You also have to set prices fairly and make it easy for people to find what they need, pay for it quickly, and then move on. None of these pillars is new, and each sounds exceedingly simple, but don't be fooled--implementing these axioms in the real world is surprisingly difficult. The author illustrates how some retailers have built successful operations by attending to these commonsense ways of dealing with their customers and how others have failed to do so.

Bergson and Derrida: A Question of Writing Time as Philosophy’s Other

Directory of Open Access Journals (Sweden)

Daniel Alipaz

2011-08-01

Full Text Available Following the 1988 publication of Bergsonism by Gilles Deleuze, many contemporary critics such as Leonard Lawlor and Paul Douglass have re-contextualized Bergson within poststructuralism. In so doing, Bergsonian theory enables us to readdress questions associated with concepts of temporality and their relation to language. In considering this re-appropriation, Suzanne Guerlac in Thinking in Time: an introduction to Henri Bergson (2006, asks why Bergson has never been considered in relation to Derrida, given that the two philosophers share fundamental concerns about time and writing. Following Derrida’s critique of Husserl in La Voix et le phénomène (1967, it is perhaps the case that many critics categorize Bergson as a phenomenologist. However, I aim to develop the argument that Guerlac instigates and show that Derrida’s critique of Husserl in fact establishes a close proximity with Bergson’s view that Western metaphysics suppresses time as durée. I will show how both Bergson and Derrida operate with the understanding of a particular rupture in the full presence of the present, an expansion of consciousness as a ‘now’ to include a constant deferral to memory. While this overlap establishes an affinity, I conclude by showing that it simultaneously marks a point of diffraction with regard to how both seek to methodologically embody such a concept of time.

The primary objective of this project is to stimulate academic interest in the conventional hydropower field by supplying research support for at least eight individual Master of Science (MS) or Doctoral (PhD) level research projects, each consisting of a graduate student supervised by a faculty member. We have completed many of the individual student research projects: 2 PhD students have finished, and 4 are still working towards their PhD degree. 4 MS students have finished, and 2 are still working towards their MS degree, one of which is due to finish this April. In addition, 4 undergraduate student projects have been completed, and one is to be completed this April. These projects were supervised by 7 faculty members and an Advisory/Review Panel. Our students and faculty have presented their work at national or international conferences and have submitted several journal publications. Three of our graduate students (Keith Martin, Dan Leonard and Hosein Foroutan) have received HRF Fellowships during the course of this project. All of the remaining students are anticipated to be graduated by the end of Fall Semester 2014. All of the tasks for this project will have been completed once all the students have been graduated, although it will be another year or two until all the journal publications have been finalized based on the work performed as part of this DOE Hydropower project.

On the Path to SunShot - Emerging Opportunities and Challenges in Financing Solar

Financial innovations—independent of technology-cost improvements—could cut the cost of solar energy to customers and businesses by 30%–60% (see Feldman and Bolinger 2016). Financing is critical to solar deployment, because the costs of solar technologies are paid up front, while their benefits are realized over decades. Solar financing has been shaped by the government incentives designed to accelerate solar deployment. This is particularly true for federal tax incentives, which have spawned complex tax-equity structures that monetize tax benefits for project sponsors who otherwise could not use them efficiently. Although these structures have helped expand solar deployment, they are relatively costly and inefficient. This has spurred solar stakeholders to develop lower-cost financing solutions such as securitization of solar project portfolios, solar-specific loan products, and methods for incorporating residential PV’s value into home values. To move solar further toward an unsubsidized SunShot future, additional financial innovation must occur. Development of a larger, more mature U.S. solar industry will likely increase financial transparency and investor confidence, which in turn will enable simpler, lower-cost financing methods. Utility-scale solar might be financed more like conventional generation assets are today, non-residential solar might be financed more like a new roof, and residential solar might be financed more like an expensive appliance. Assuming a constant, SunShot-level installed PV system price, such financing innovations could reduce PV’s LCOE by an estimated 30%–60% (depending on the sector) compared with historical financing approaches.

How Does Your Brain See “Living” Circles: A Study of Animacy and Intention Using fMRI

Directory of Open Access Journals (Sweden)

P McAleer

2011-04-01

Full Text Available It is widely reported that the perception of animacy can occur from simple displays of moving shapes with participants attributing such qualities as goals, beliefs, and intentions. Furthermore, via neuroimaging studies, a network of brain areas, including regions of the temporal and frontal lobes, has been shown to process the percept. However, problems exist that prevent the bridging of fMRI studies on the perception of animacy and intention in shapes to the same percept of human movement. First, the issue of prior displays being poorly controlled in terms of low-level visual cues blurs the actual root of the effect. Second, the general use of synthetically generated displays and their relationship to actual human movement: a problem previously addressed in behavioural studies via a systematic reduction of live visual footage of human actors. Therefore, we propose experiments that incorporate both synthetically generated animacy stimuli and displays derived from human motion. Following the classic Tremoulet and Feldman displays, stimuli are created that allow for manipulation of animacy and intent whilst controlling low-level visual cues. These displays are then used in a whole-brain fMRI study to locate neural regions sensitive to the perception of animacy and intention. Finally, within these regions, a region-of-interest analysis is performed to examine the change in brain activation from viewing animacy displays derived from human movement with varying intent (eg, chasing or following. This study develops the relationship between previous animacy literature and the real-world perception of intent.

The neuroimaging approach to the assessment of mild cognitive impairment

International Nuclear Information System (INIS)

Lucignani, Giovanni

2006-01-01

Imaging techniques, including emission tomography and magnetic resonance imaging, are progressively being exploited for the classification and prognostic evaluation (indispensable for possible treatments) of mild cognitive impairment (MCI). The main traits of MCI and unsolved issues in its assessment are discussed in two review articles by Feldman and Jacova from the Division of Neurology, Dept. of Medicine, Clinic for Alzheimer Disease and Related Disorders, University of British Columbia, in Vancouver, Canada [1] and Chong and Sahadevan from the Department of Geriatric Medicine, Tan Tock Seng Hospital, Jalan Tan Tock Seng, Singapore [2]. Because MCI has different presentations in terms of the type and degree of cognitive deficits observed, several clinical subtypes of MCI besides the amnestic form have now been recognised and characterised on the basis of deficits in different cognitive domains, either in isolation or in combination with amnesia. The different subtypes of MCI suggest that MCI has a heterogeneous nature, with several possible causes that lead to the same symptoms. This is a field in evolution, and a uniform diagnostic classification of MCI has not yet been accomplished. Lopez et al. from the Departments of Neurology and Psychiatry, University of Pittsburgh, School of Medicine,Pittsburgh, Pennsylvania, USA [3] point out that the classification of MCI subtypes is useful to improve prediction of the subsequent risk of dementia and the type of dementia, and that the manner in which MCI subjects are classified into subgroups has implications for the cognitive profile of the group and thus for our inferences about the aetiology and possible clinical course of the disorder

The History of Hiatal Hernia Surgery

2005-01-01

Objective: This review addresses the historical evolution of hiatal hernia (HH) repair and reports in a chronological fashion the major milestones in HH surgery before the laparoscopic era. Methods: The medical literature and the collections of the History of Medicine Division of the National Library of Medicine were searched. Secondary references from all sources were studied. The senior author's experience and personal communications are also reported. Results: The first report of HH was published in 1853 by Bowditch. Rokitansky in 1855 demonstrated that esophagitis was due to gastroesophageal reflux, and Hirsch in 1900 diagnosed an HH using x-rays. Eppinger diagnosed an HH in a live patient, and Friedenwald and Feldman related the symptoms to the presence of an HH. In 1926, Akerlund proposed the term hiatus hernia and classified HH into the 3 types that we use today. The first elective surgical repair was reported in 1919 by Soresi. The physiologic link between HH and gastroesophageal reflux was made at the second half of the 20th century by Allison and Barrett. In the midst of a physiologic revolution, Nissen and Belsey developed their famous operations. In 1957, Collis published his innovative operation. Thal described his technique in 1965, and in 1967, Hill published his procedure. Many modifications of these procedures were published by Pearson and Henderson, Orringer and Sloan, Rossetti, Dor, and Toupet. Donahue and Demeester significantly improved Nissen's operation, and they were the first to truly understand its physiologic mechanism. Conclusion: Hiatal hernia surgery has evolved from anatomic repair to physiological restoration. PMID:15622007

Imaging techniques, including emission tomography and magnetic resonance imaging, are progressively being exploited for the classification and prognostic evaluation (indispensable for possible treatments) of mild cognitive impairment (MCI). The main traits of MCI and unsolved issues in its assessment are discussed in two review articles by Feldman and Jacova from the Division of Neurology, Dept. of Medicine, Clinic for Alzheimer Disease and Related Disorders, University of British Columbia, in Vancouver, Canada [1] and Chong and Sahadevan from the Department of Geriatric Medicine, Tan Tock Seng Hospital, Jalan Tan Tock Seng, Singapore [2]. Because MCI has different presentations in terms of the type and degree of cognitive deficits observed, several clinical subtypes of MCI besides the amnestic form have now been recognised and characterised on the basis of deficits in different cognitive domains, either in isolation or in combination with amnesia. The different subtypes of MCI suggest that MCI has a heterogeneous nature, with several possible causes that lead to the same symptoms. This is a field in evolution, and a uniform diagnostic classification of MCI has not yet been accomplished. Lopez et al. from the Departments of Neurology and Psychiatry, University of Pittsburgh, School of Medicine,Pittsburgh, Pennsylvania, USA [3] point out that the classification of MCI subtypes is useful to improve prediction of the subsequent risk of dementia and the type of dementia, and that the manner in which MCI subjects are classified into subgroups has implications for the cognitive profile of the group and thus for our inferences about the aetiology and possible clinical course of the disorder.

In the first half of 1995, the Anglo-Australian Observatory is due to commission a wide field (2.1(deg) ), 400-fiber, double spectrograph system (2dF) at the f/3.3 prime focus of the AAT 3.9m bi-national facility. The instrument should be able to measure ~ 4000 galaxy redshifts (assuming a magnitude limit of b_J ~\\ 20) in a single dark night and is therefore ideally suited to studies of large-scale structure. We have carried out simple 3D numerical simulations to judge the relative merits of sparse surveys and contiguous surveys. We generate a survey volume and fill it randomly with particles according to a selection function which mimics a magnitude-limited survey at b_J = 19.7. Each of the particles is perturbed by a gaussian random field according to the dimensionless power spectrum k(3) P(k) / 2pi (2) determined by Feldman, Kaiser & Peacock (1994) from the IRAS QDOT survey. We introduce some redshift-space distortion as described by Kaiser (1987), a `thermal' component measured from pairwise velocities (Davis & Peebles 1983), and `fingers of god' due to rich clusters at random density enhancements. Our particular concern is to understand how the window function W(2(k)) of the survey geometry compromises the accuracy of statistical measures [e.g., P(k), xi (r), xi (r_sigma ,r_pi )] commonly used in the study of large-scale structure. We also examine the reliability of various tools (e.g. genus) for describing the topological structure within a contiguous region of the survey.

Soil water erosion on cultivated lands is a severe threat to soil resources in the world (Leh et al., 2013; Zhao et al., 2013). In particular, Mediterranean areas deserve a particular attention because of their edaphic, topographic and climatic conditions. Among the cultivated lands, concerns have arisen about vineyards because, aside representing one of the most important crop in terms of income and employment, they also have proven to be the form of agricultural land that causes one of the highest soil losses (Tropeano et al., 1984; Leonard and Andrieux, 1998; Ferrero et al., 2005; Cerdà et al., 2007; Blavet et al., 2009; Casalí et al., 2009; Novara et al., 2011; Martínez Casasnovas et al., 2013; Ruiz Colmenero et al., 2013; Tarolli et al., 2014). Although the topic of soil water erosion on vineyards has been studied, it still raises uncertainties. These are due to the i) high complexity of processes involved, ii) different methodologies used to analyze them and iii) analyses carried out at different spatial and temporal scales. At this regard, this work aims to evaluate the impact of factors controlling erosion such as rainfall characteristics, topography, soil properties and soil and water conservation techniques. Data derived from experimental plots have been reviewed. At first, what emerges is the difficulty of comparing erosion rates obtained with different methodologies and at different spatial scales. Secondly, all the factors demonstrate to have a strong impact on soil erosion but a 'general rule' upon which to consider one factor always predominant over the others does not come out. Therefore, this work supports the importance of monitoring soil water erosion by field measurements to better understand the relationship between the factors. Variables like rainfall characteristics, topography and soil properties are much more difficult to modify than the soil and water management techniques. Hence, future researches are needed to both recommend the best

“Protective Bystander Effects Simulated with the State-Vector Model”—HeLa x Skin Exposure to 137Cs Not Protective Bystander Response But Mammogram and Diagnostic X-Rays Are

The recent Dose Response journal article “Protective Bystander Effects Simulated with the State-Vector Model” (Schollnberger and Eckl 2007) identified the suppressive (below natural occurring, zero primer dose, spontaneous level) dose response for HeLa x skin exposure to 137Cs gamma rays (Redpath et al 2001) as a protective Bystander Effect (BE) behavior. I had previously analyzed the Redpath et al (2001) data with a Microdose Model and conclusively showed that the suppressive response was from Adaptive Response (AR) radio-protection (Leonard 2005, 2007a). The significance of my microdose analysis has been that low LET radiation induced single (i.e. only one) charged particle traversals through a cell can initiate a Poisson distributed activation of AR radio-protection. The purpose of this correspondence is to clarify the distinctions relative to the BE and the AR behaviors for the Redpath groups 137Cs data, show conversely however that the Redpath group data for mammography (Ko et al 2004) and diagnostic (Redpath et al 2003) X-rays do conclusively reflect protective bystander behavior and also herein emphasize the need for radio-biologist to apply microdosimetry in planning and analyzing their experiments for BE and AR. Whether we are adamantly pro-LNT, adamantly anti-LNT or, like most of us, just simple scientists searching for the truth in radio-biology, it is important that we accurately identify our results, especially when related to the LNT hypothesis controversy.

Transitions to absorbing states are of fundamental importance in nonequilibrium physics as well as ecology. In ecology, absorbing states correspond to the extinction of species. We here study the spatial population dynamics of three cyclically interacting species. The interaction scheme comprises both direct competition between species as in the cyclic Lotka-Volterra model, and separated selection and reproduction processes as in the May-Leonard model. We show that the dynamic processes leading to the transient maintenance of biodiversity are closely linked to attractors of the nonlinear dynamics for the overall species' concentrations. The characteristics of these global attractors change qualitatively at certain threshold values of the mobility and depend on the relative strength of the different types of competition between species. They give information about the scaling of extinction times with the system size and thereby the stability of biodiversity. We define an effective free energy as the negative logarithm of the probability to find the system in a specific global state before reaching one of the absorbing states. The global attractors then correspond to minima of this effective energy landscape and determine the most probable values for the species' global concentrations. As in equilibrium thermodynamics, qualitative changes in the effective free energy landscape indicate and characterize the underlying nonequilibrium phase transitions. We provide the complete phase diagrams for the population dynamics and give a comprehensive analysis of the spatio-temporal dynamics and routes to extinction in the respective phases.

Full Text Available History on Dutch TelevisionIn ‘Dat is wel eens anders geweest!’ [It was different then!] Paul Knevel and Jouke Turpijn attempt to provide tools for historians to analyse history on the television in a broad historiographical perspective. They cover the first history productions in the Netherlands and the remarkable success of major series in the twentyfirst century. The difficult relation between academic and public history on the television in the Netherlands is placed in an international context. A Critical Look at Ten Oorlog [To War] reflects critically on the popular television programme Ten Oorlog,thereby examining the field of tension between history and entertainment, between historians and ‘the public’. In ‘Dat is wel eens anders geweest!’ reiken Paul Knevel en Jouke Turpijnhandvatten aan om geschiedenis op televisie in een breed histori(ografisch perspectief te duiden. Vertrekkend vanaf de eerste producties bespreken zij het wonderbaarlijke succes van geschiedenisseries in de eenentwintigste eeuw. Zij staan stil bij de moeizame relatie in Nederland tussen academische geschiedenis engeschiedenis op televisie en vergelijken dit met andere landen. Hans Boers, Jelena Dobbels en Ingrid Leonard werpen een kritische blik op het populaire televisieprogramma Ten Oorlog en gaat daarbij in op het spanningsveld tussen geschiedenis en entertainment, tussen historici en ‘het publiek’. Geschiedenis kan via verschillende formats zoals een historische documentaire of een reisprogramma aan bod komen op televisie.
