Full Text Available Profound changes are taking place within working life, where established boundaries between work and personal life are challenged by increased global competition, ever-faster changing markets, and rapid development of boundary transcending information and communication technologies (ICT. The aim of this study was to investigate boundary management preferences in terms of keeping work and personal life domains separated or integrated, that is, segmenting or blending of domains, the perception of being in control of one´s preferred boundaries, and work-life balance among employees at a Swedish telecom company (N = 1,238, response rate 65%, men 73%, mean age 42 years. Psychosocial work factors, individual characteristics, sociodemographic factors, and work-life balance were investigated in relation to boundary management preferences and perceived boundary control. For high boundary control among segmenters, nearly all the studied psychosocial work factors were significant. Among integrators, this was the case only for clear expectations in work. For both groups, the individual capacity for self-regulation was associated with high boundary control. Regarding sociodemographic factors, cohabiting women with children who preferred segmentation had low boundary control. Finally, there was a main effect of boundary control on work-life balance. In particular, male segmenters perceiving high boundary control had better work-life balance than all others. Conclusions of the study are that segmenters need external boundaries in work for succesful boundary management. Moreover, self-regulation seems a crucial boundary competence in knowledge- intensive, flexible work. Results are of value for health promotion in modern work organizations in supporting employees achieving successful boundary control and subsequent work-life balance.

Sociologia e história na obra de José de Souza Martins

Directory of Open Access Journals (Sweden)

William Héctor Gómez Soto

Full Text Available Resumo O autor analisa a sociologia de José de Souza Martins, centrando a atenção em sua perspectiva teórica e seu método dialético. Martins escolhe como objeto aquilo que está à margem da sociedade e das ciências sociais, como, por exemplo, o destino das populações rurais, os sonhos dos trabalhadores das grandes cidades, a aparição do demônio numa fábrica e a vida cotidiana do homem simples. Discípulo de Florestan Fernandes, Martins dialoga com Marx e Lefebvre, dos quais toma duas noções fundamentais: a de menos-valia e a de resíduo. O autor deste artigo destaca que essas duas noções, aparentemente insignificantes, são a chave para compreender a contribuição de Martins. Na sociologia de Martins, o que está à margem e que é liminar não apenas é um tema como também, e principalmente, um recurso metodológico.

Purple martins are cavity-nesting swallows that once nested fairly widely in California’s oak woodlands but are now rare in that habitat. The old oaks of the Tehachapi Range (southern Sierra Nevada) may now host the last martins that nest in oak woodlands, with approximately 100-200 pairs or about 15 percent of the California population. In summer of 2000, we found 57...

HEALTH COVER, THE CASE OF MARTIN AND CAROLINA IN AUSTRALIA

Directory of Open Access Journals (Sweden)

Maximiliano E KORSTANJE

2014-07-01

Full Text Available This research examines, from a qualitative perspective, some public opinion related to issues associated with the management of a tensed situation. In that process, it identifies some of the subtle differences in the Anglo-Latino cultural expectations. Martin, an Argentine tourist, contracted the Gullien-Barre syndrome in Australia, while enjoying his honeymoon vacation on a Tasmanian island with his partner Carolina. With the passing of days, Martin lost his mobility and was finally hospitalized in emergency. Doctors induced Martin into a coma temporarily because his muscles were paralyzed by the action of the virus. Health costs were more expensive than the family could absorb in Australia. The family had to request the intervention of the Argentine embassy and chancellery for help. In other words, this incident contrasts two world views: hospitality as the institution that historically developed to care and protect travelers versus hospitality as the commercial practice of exploitation.

Constructing integrable full-pressure full-current free-boundary stellarator magnetohydrodynamic equilibrium solutions

International Nuclear Information System (INIS)

Hudson, S.R.

2002-01-01

For stellarators to be feasible candidates for fusion power stations it is essential that the magnetic field lines lie on nested flux surfaces; however, the lack of a continuous symmetry implies that magnetic islands, caused by Pfirsch-Schlueter currents, diamagnetic currents and resonant coil fields, are guaranteed to exist. The challenge is to design the plasma and coils such that these effects cancel. Magnetic islands in free-boundary full-pressure full-current stellarator magnetohydrodynamic equilibria are suppressed using a procedure based on the PIES code [Comp. Phys. Comm., 43:157, 1986] which iterates the equilibrium equations to obtain the plasma equilibrium. At each iteration, changes to a Fourier representation of the coil geometry are made to cancel resonant fields produced by the plasma. The changes are constrained to lie in the nullspace of certain measures of engineering acceptability and kink stability. As the iterations continue, the coil geometry and the plasma simultaneously converge to an equilibrium in which the island content is negligible. The method is applied to a candidate plasma and coil design for NCSX [Phys. Plas., 7:1911, 2000]. (author)

Bertlmann-Martin inequalities in hypernuclei

International Nuclear Information System (INIS)

Lombard, R.J.; Marcos, S.; Mares, J.

1994-01-01

Inequalities have been established by Bertlmann and Martin which link the rms radius and the kinetic energy of the 1s orbit to the lowest dipole transition energy. The derivation is based on the Thomas-Reiche-Kuhn sum rule, which requires a local Hamiltonian. In the present work, we extend these inequalities to Hamiltonian where the nonlocality can be expressed via spatial dependent effective mass. We discuss the case of hypernuclei, which provides a suitable example to verify the Bertlmann-Martin inequalities

Professor André Martin has been awarded the I.Ya.Pomeranchuk Prize 2010, alongside Professor Valentine Zakharov.   André Martin, CERN theorist, pictured at the ceremony held in honour of his 80th birthday (August 2009). Established by the Institute of Theoretical and Experimental Physics (ITEP) in memory of an outstanding scientist Isaak Yakovlevich Pomeranchuk, the prize is awarded for the study of analytic properties of the scattering amplitude; which lead to the Froissart—Martin bound on the cross section growth with energy. The prize comes as a great honor for Martin, who was in fact a good friend of Mr. Pomeranchuk, "I am surprised and delighted to learn that I will be receiving the 2010 Pomeranchuk Prize. I was an admirer of Pomeranchuk and we shared a great friendship. I met with him for the last time in Erevan (Armenia) in 1965. As a good-bye, he told me, 'Analyticity exists'. This is precisely what I proved to earn the prize"....

Characterization of the Boundary Layer on Full-Scale Bluefin Tuna

Science.gov (United States)

Amaral, Brian; Cipolla, Kimberly; Henoch, Charles

2014-11-01

The physics that enable tuna to cross large expanses of ocean while feeding and avoiding predators is not presently understood, and could involve complex control of turbulent boundary layer transition and drag reduction. Typical swimming speeds of Bluefin tuna are 1-2 m/s, but can be higher during strong accelerations. The goal of this work is to experimentally determine the approximate lateral location at which transition to turbulence occurs on the tuna for various speeds. The question is whether laminar flow or an advanced propulsion mechanism (or both) allows them to swim at high speeds. Uncertainties include the surface roughness of the skin, local favorable and adverse pressure gradients, and discontinuities such as the open mouth or juncture at the fins. Historically, much of the fluid mechanics work in the area of fish locomotion has focused on vortex shedding issues rather than the boundary layer. Here, the focus is obtaining information on the boundary layer characteristics of a rigid tuna model. A full scale model of a Pacific Bluefin tuna was fabricated using a mold made from an actual deceased tuna, preserving the surface features and details of the appendages. The model was instrumented with 32 wall pressure sensors and experiments performed in a tow tank. Results from flow visualization, drag and wall pressure measurements over a range of speeds and varying angles of attack will be presented.

Martin Luther in Primetime. Television Fiction and Cultural Memory Construction in Cold War Germany

Directory of Open Access Journals (Sweden)

Stewart Anderson

2013-06-01

Full Text Available In 1983, both East and West Germany celebrated Martin Luther’s 500th birthday with great fanfare.  Nowhere was this competition more provocative and visually arresting, however, than in two multi-part television plays which depicted Luther’s life: the West German Martin Luther, broadcast by the public station ZDF in April, and the East German title of the same name, aired in October.  In this essay, I argue that the East German version constituted an appropriative strategy of memory formation – one which depicted Luther’s positive qualities and grafted them into the Marxist canon of heroes.  In contrast, the ZDF Martin Luther, which featured a highly rational Luther, projected what Jan Assmann has termed a normative strategy of harnessing Luther’s memory, focusing on Luther’s intellectual arguments and anti-radicalism.

Wilson Martins: between the intelligentsia and the university (1951

Full Text Available Abstract The purpose of this article is to analyze the presence of Ortega y Gasset in the Parana’s State group during the 1950s, especially his influence in the thinking of Wilson Martins, and to emphasize the debate on the ideas of the intellectual and the university. The article discusses about the contributions of this Parana’s thinker on the Parana’s university teaching constituting and organizing process, and emphasizes that the Wilson Martins’ role consisted in promoting the debate on the presence of the intellectual person in modern society, attributing the mission as guardian of the moral and herald of cultural renovation, without forgetting the Brazilian and European political-cultural context as the founding background to higher education. It bases itself on the speech entitled “The rebellion against intelligence and the mission of the university”, that occurred at the University of Parana in 1951, and on the work The History of Brazilian Intelligence, written by Wilson Martins.

St. John le calviniste, ou l’émule de Gil-Martin Charlotte Brontë’s Calvinist St. John Emulating James Hogg’s Gil-Martin

Directory of Open Access Journals (Sweden)

Jean Berton

2009-07-01

Full Text Available This article aims to show how far Hogg’s archetypal character, Gil-Martin, influenced Charlotte Brontë’s enigmatic character, St. John, who appears in chapters XXVI to XXXV and is mentioned again in the conclusion of Jane Eyre. Some unexpected words, like “glen”, in a greater Yorkshire area, operate as keywords to a “deep context” study in a neo-contextualist approach. Even though St. John cannot be mistaken for a double of Gil-Martin, a fair number of details tend to prove that James Hogg’s Private Memoirs and Confessions of a Justified Sinner deeply influenced Charlotte Brontë—both pride-driven St. John and Gil-Martin stand for demonic despotism. Yet, if Gil-Martin is a straightforward Gothic illustration of Satan, St. John is a reincarnation of a marble-cold Apollo in a dogma-trapped Calvinist. Brontë’s intention was not so much to denounce noxious excesses in religious beliefs as to set her heroine’s wise independence against nefarious male domination: whereas victimised Robert Wringhim is driven to despair and suicide, self-reliant Jane Eyre escapes from St. John’s grip. In both narratives relationships between men and women are shown as tragically warped by religious behavioural extravagance, but only the female character is granted a positive outcome to serve an optimistic view on life: Robert Wringhim is violently wrung out of the society of men and women, St. John Rivers, from “Marsh End”, blindly drifts away to his death in India, and airy Jane, of “Moor House”, wafts away to anchor to Edward Rochester, the sender of the airwave-born call.

Free-boundary Full-pressure Island Healing in a Stellarator: Coil-healing

International Nuclear Information System (INIS)

Hudson, S.R.; Reiman, A.; Strickler, D.; Brooks, A.; Monticello, D.A.; Hirshman, S.P.

2002-01-01

The lack of axisymmetry in stellarators guarantees that in general magnetic islands and chaotic magnetic field lines will exist. As particle transport is strongly tied to the magnetic field lines, magnetic islands and chaotic field lines result in poor plasma confinement. For stellarators to be feasible candidates for fusion power stations it is essential that, to a good approximation, the magnetic field lines lie on nested flux-surfaces, and the suppression of magnetic islands is a critical issue for stellarator coil design, particularly for small aspect ratio devices. A procedure for modifying stellarator coil designs to eliminate magnetic islands in free-boundary full-pressure magnetohydrodynamic equilibria is presented. Islands may be removed from coil-plasma free-boundary equilibria by making small changes to the coil geometry and also by variation of trim coil currents. A plasma and coil design relevant to the National Compact Stellarator Experiment is used to illustrate the technique

The January 2006 Volcanic-Tectonic Earthquake Swarm at Mount Martin, Alaska

Science.gov (United States)

Dixon, James P.; Power, John A.

2009-01-01

On January 8, 2006, a swarm of volcanic-tectonic earthquakes began beneath Mount Martin at the southern end of the Katmai volcanic cluster. This was the first recorded swarm at Mount Martin since continuous seismic monitoring began in 1996. The number of located earthquakes increased during the next four days, reaching a peak on January 11. For the next two days, the seismic activity decreased, and on January 14, the number of events increased to twice the previous day's total. Following this increase in activity, seismicity declined, returning to background levels by the end of the month. The Alaska Volcano Observatory located 860 earthquakes near Mount Martin during January 2006. No additional signs of volcanic unrest were noted in association with this earthquake swarm. The earthquakes in the Mount Martin swarm, relocated using the double difference technique, formed an elongated cluster dipping to the southwest. Focal mechanisms beneath Mount Martin show a mix of normal, thrust, and strike-slip solutions, with normal focal mechanisms dominating. For earthquakes more than 1 km from Mount Martin, all focal mechanisms showed normal faulting. The calculated b-value for the Mount Martin swarm is 0.98 and showed no significant change before, during, or after the swarm. The triggering mechanism for the Mount Martin swarm is unknown. The time-history of earthquake occurrence is indicative of a volcanic cause; however, there were no low-frequency events or observations, such as increased steaming associated with the swarm. During the swarm, there was no change in the b-value, and the distribution and type of focal mechanisms were similar to those in the period before the anomalous activity. The short duration of the swarm, the similarity in observed focal mechanisms, and the lack of additional signs of unrest suggest this swarm did not result from a large influx of magma within the shallow crust beneath Mount Martin.

On 2 January 1995 Martin Stutzmann became Editor-in-Chief of physica status solidi, replacing Professor E. Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality.Martin

FULL GPU Implementation of Lattice-Boltzmann Methods with Immersed Boundary Conditions for Fast Fluid Simulations

Directory of Open Access Journals (Sweden)

G Boroni

2017-03-01

Full Text Available Lattice Boltzmann Method (LBM has shown great potential in fluid simulations, but performance issues and difficulties to manage complex boundary conditions have hindered a wider application. The upcoming of Graphic Processing Units (GPU Computing offered a possible solution for the performance issue, and methods like the Immersed Boundary (IB algorithm proved to be a flexible solution to boundaries. Unfortunately, the implicit IB algorithm makes the LBM implementation in GPU a non-trivial task. This work presents a fully parallel GPU implementation of LBM in combination with IB. The fluid-boundary interaction is implemented via GPU kernels, using execution configurations and data structures specifically designed to accelerate each code execution. Simulations were validated against experimental and analytical data showing good agreement and improving the computational time. Substantial reductions of calculation rates were achieved, lowering down the required time to execute the same model in a CPU to about two magnitude orders.

Three Decades Investigating Humor and Laughter: An Interview With Professor Rod Martin.

Science.gov (United States)

Martin, Rod; Kuiper, Nicholas A

2016-08-01

Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin's research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin's earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin's subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin's comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

Pronouncing that being is nothing in the work of Martin Heidegger

Directory of Open Access Journals (Sweden)

Grbić Safer

2017-01-01

Full Text Available Raising a question of Being, anew, after it had fallen into oblivion, was initiated by Martin Heidegger and that marked his complete philosophical work. Along those lines, the paper titled 'Pronouncing That Being is Nothing in the Work of Martin Heidegger' briefly discusses the history of the question of Being starting from the Parmenides' research on the topic, through Christian dogma, Hegel's Science of Logic and establishing Being-Dasein-Nothing, all the way to the Heidegger's distinction among Being, Dasein, and Nothing in the anxiety phenomenon along the lines of existential thinking of Kierkegaard. The hypothesis as a judgment that is presumed to be true in order to explain certain facts with it or as an assumption on the basis of facts reflects in the thesis that Heidegger, asking the question about the meaning of Being and the tendency of getting to his concept in the anxiety phenomenon, especially in his later speeches, gets to pronounce that Being is Nothing, without providing final answers, but considering that just asking the question about such a relation is a success.

I agree with Vivian Martin that ‘authenticating’ works better for early jazz and first wave USA revivalism (including Bunk Johnson and would like to say that at the time I wrote the abstract, I was favouring ‘managing authenticity’ over ‘authenticating’ as the core category in order to provide a more embracive category within which to consider early jazz, the 1940s New Orleans jazz revival (including Bunk Johnson, and the world-wide New Orleans jazz revivalist movement which continues to this day.

2018-04-01

ABSTRACT: April 4, 2018 commemorates the fiftieth anniversary of the death of Martin Luther King jr., in Memphis-Tennessee. The importance of Martin Luther King’s personality goes far beyond the borders of United States and spreads on the global scale. The present paper concerns the universality and the present impact of Martin Luther King’s legacy, considering also the European context. The paper analyses in brief the history of Martin Luther King, taking into account both his activism in the US and his international criticism against global issues such as post-colonialism and third-worldism; a second part is dedicated to the so called religious “global left” of the 50s and 70s. Conclusions show how and why the global religions have still to be considered a critical background for the rule of law, its inequalities and its injustices.

Olson, Peter

Owen Martin Phillips, a pioneer in geophysical fluid dynamics, died at home on 13 October 2010 in Chestertown, Md., at the age of 79. To his many friends and colleagues, Phillips was an inspirational and gracious person who combined a deep intellect, a lively spirit, and a generous heart that matched his passionate interest in the geophysical sciences. Phillips was born on 30 December 1930 in Parramatta, N. S. W., Australia. In 1948 he enrolled in the University of Sydney, where he earned a B.S. in applied mathematics in 1952. That same year, he joined the Cavendish Laboratory at Cambridge University as a research student, where he began to apply to the ocean concepts in turbulent flow recently developed by Andrei Kolmogorov, G. I. Taylor, and George Batchelor. While attending the 1956 celebration of Taylor's seventieth birthday, Phillips heard Fritz Ursell declare that “the process by which ocean waves are generated by the wind cannot be regarded as known.” In 1957 the Journal of Fluid Mechanics contained two remarkable papers offering contrasting theories for ocean wave generation. One paper, by the applied mathematician John Miles (J. Fluid Mech., 2(5), 417-445, 1957), proposed that energy transfer from the air to the sea occurs at a critical layer in the atmosphere boundary layer. The other paper, by Phillips, then 26 years old (J. Fluid Mech., 3(2), 185-204, 1957), proposed that turbulent pressure fluctuations in the wind resonate with propagating ocean waves, forcing them to grow. Together these became known as the Phillips-Miles process, and it was the opening salvo in Phillips's 50-year career of innovative contributions to geophysics through fluid mechanics.

THEOLOGYOF DIALOGUE. MARTIN BUBER AND CHRISTIANITY

Directory of Open Access Journals (Sweden)

G. ZAVERSHINSKY

2011-06-01

Full Text Available Martin Buber is one of pioneers of the dialog method, which is to complete the standard subject-object approach in the humanities. It was he, who had shaped the classic form to this method and attempted to use it when developing relationship patterns between Judaism and Christianity. In the author’s view, Buber failed in this attempt, as it shows the study of his work «Zwei Glaubensweisen». It had happened because of Buber’s not quite «dialogical» views on person of Christ and lack of good acquaintance with all the complexity and diversity of the Christian thought. Buber could not interpret properly the St. Paul’s thought without considering hypostatic communication with God as it is presented in the orthodox theology. In spite of this the author believes that fruits of Buber’s labor in the dialogue philosophy still can be in many ways useful for Christian theology and practice

Clinical repercussions of Martin-Gruber anastomosis: anatomical study

Directory of Open Access Journals (Sweden)

Cristina Schmitt Cavalheiro

2016-04-01

Full Text Available OBJECTIVE: The main objective of this study was to describe Martin-Gruber anastomosis anatomically and to recognize its clinical repercussions. METHOD: 100 forearms of 50 adult cadavers were dissected in an anatomy laboratory. The dissection was performed by means of a midline incision along the entire forearm and the lower third of the upper arm. Two flaps including skin and subcutaneous tissue were folded back on the radial and ulnar sides, respectively. RESULTS: Nerve communication between the median and ulnar nerves in the forearm (Martin-Gruber anastomosis was found in 27 forearms. The anastomosis was classified into six types: type I: anastomosis between the anterior interosseous nerve and the ulnar nerve (n = 9; type II: anastomosis between the anterior interosseous nerve and the ulnar nerve at two points (double anastomosis (n = 2; type III: anastomosis between the median nerve and the ulnar nerve (n = 4; type IV: anastomosis between branches of the median nerve and ulnar nerve heading toward the flexor digitorum profundus muscle of the fingers; these fascicles form a loop with distal convexity (n = 5; type V: intramuscular anastomosis (n = 5; and type VI: anastomosis between a branch of the median nerve to the flexor digitorum superficialis muscle and the ulnar nerve (n = 2. CONCLUSION: Knowledge of the anatomical variations relating to the innervation of the hand has great importance, especially with regard to physical examination, diagnosis, prognosis and surgical treatment. If these variations are not given due regard, errors and other consequences will be inevitable.

Nietzsche, autobiography, history: mourning and Martin and John.

Science.gov (United States)

Champagne, J

1998-01-01

How might gay and lesbian literature be read not as a mimetic representation of homosexuality, but as an activity linked to problems of subjectivity and historiography? Reading Dale Peck's novel Martin and John alongside passages from Friedrich Nietzsche's "On the Uses and Disadvantages of History for Life" and Sigmund Freud's "Mourning and Melancholia," this essay argues for an understanding of Peck's text as an attempt to link two apparently different processes of import to contemporary gay male subjects in particular: the writing of what Nietzsche terms "critical history," and the mourning of those lost to HIV disease. It concludes by linking Martin and John to feminist critiques of identity and traditional historiography, as well as noting the connection between these two critiques.

Martin L. Perl (1927-2014): A Biographical Memoir

Science.gov (United States)

Feldman, Gary; Jaros, John; Schindler, Rafe H.

2017-10-01

Particle physicist Martin Lewis Perl was recognized worldwide for his discovery of the τ (tau) lepton. For that achievement he received the 1982 Wolf Prize and shared the 1995 Nobel Prize in Physics. He was also a Fellow of the American Physical Society and a member of the National Academy of Sciences (elected 1981). Martin's distinctive approach to scientific investigation had its origins in his upbringing and in the influence of I. I. Rabi, his graduate advisor at Columbia University. After coming to Stanford University in 1963, Martin sought to understand why there should be two and only two families of leptons: the electron and its associated neutrino; and the muon and the muon neutrino. His discovery of the τ provided evidence for a third family of fundamental leptons. The bottom quark was discovered shortly afterward at the Fermi National Accelerator Laboratory, providing evidence for a third family of quarks. Direct evidence for the τ neutrino came later, thereby completing the third lepton generation, while the discovery of the top quark in 1995 completed the third generation of quarks. These achievements established leptons and quarks as fundamental constituents of matter and, along with the fundamental forces, provided the experimental basis of the "Standard Model," our picture of how all matter is made up and how its components interact. Why there are three and only three families of leptons and quarks remains an unsolved mystery to this day.

O zoneamento da vulnerabilidade natural à perda de solo foi elaborado com base nas informações referentes à declividade, geomorfologia, geologia e solos de acordo com o grau de vulnerabilidade de cada informação, por meio da álgebra de mapas. Para o território municipal de Silveira Martins identificou-se a ocorrência de cinco classes. Destacam-se as unidades estáveis com predomínio dos processos formadores do solo (38,08% da área municipal, e as unidades moderadamente vulneráveis, prevalecendo os processos erosivos (53,67%. As áreas classificadas como moderadamente vulnerável e vulnerável (8,25%, correspondem a áreas com inclinações superiores a 25º e com formação geológica e geomorfológica menos estáveis. Nas unidades em que predominou a vulnerabilidade natural, sugere-se especial atenção em relação ao meio natural e aos agentes que o influenciam, visando boas práticas sociais associadas às políticas ambientais no processo de tomada de decisões econômicas, possibilitando a valorização e proteção do meio natural.

Full Text Available Martin Walser’s play Eiche und Angora (1962 deals with the persistence of totalitarianism-oriented mental structures after the Second World War and the collapse of the Nazi regime. Walser represents political history as strongly opposed to the private sphere of ordinary people. Adjustment to the post-war situation of the Bundesrepublik and continuity with the historical past are seen by Walser as equivalent forms of self-defense against the inhuman attitude of political power.

About an inch inferior to the elbow joint, three branches arose from the median nerve. These were the anterior interosseous branch, a Martin-Gruber branch (MGB and a muscular branch. The MGB coursed infero-medially to join with the ulnar nerve by running posterior to the ulnar artery. It was surprising to observe that the MGB passed between the ulnar artery and its venae comitantes. There was an acute angulation of the MGB here, suggesting entrapment at this site.

All in the family: a belated response to Knudson-Martin's feminist revision of Bowen theory.

Science.gov (United States)

Horne, K Blake; Hicks, Mary W

2002-01-01

The first formal attempt at revising Bowen theory within the marriage and family therapy literature is represented in the work of Knudson-Martin (1994). Claiming that several of the theory's concepts are defined at odds with female development, Knudson-Martin (1994) reconceptualizes and expands Bowen theory to rectify these perceived shortcomings. In turn, we address several fundamental concerns with Knudson-Martin's critique and revision of Bowen theory. An alternative representation of Bowen Theory, as well as its relationship to feminist thought, is put forth. Suggestions for the field's future relationship to Bowen theory are also discussed.

Uranium deposits in the Beaverlodge area, northern Saskatchewan: their relationship to the Martin Group (Proterozoic) and the underlying basement

International Nuclear Information System (INIS)

Mazimhaka, P.K.; Hendry, H.E.

1989-01-01

The rocks of the Martin Group crop out in an area 60 km by 50 km north of Lake Athabasca near Uranium City, northern Saskatchewan. This area has numerous uranium showings within a few kilometres of the unconformity below the Martin Group. Mineralization occurs in fault zones, in basement rocks and in sedimentary and volcanic rocks of the Martin Group. Martin Group sediments accumulated in alluvial fans, braided streams, and ephemeral lakes. The thickest sequence (8 km to 10 km) is preserved in the Beaverlodge area, near Uranium City. The style of sedimentation changed through time as the basin evolved from deposition of conglomeratic detritus along fault scarps to the accumulation of silt in ephemeral lakes. The uneven nature of the sub-Martin unconformity surface, the lithotype of the lowermost conglomerates and breccias (Beaverlodge Formation), and the shape of the basin fill indicate deposition in fault-controlled basins. The earliest economic uranium mineralization in the rocks of the Martin Group was epigenetic. The mineralization was coeval with that in basement rocks. Economic mineralization in basement rocks and in the lowermost formation of the Martin Group is close to the unconformity. Epigenetic uranium mineralization thus appears to have resulted from processes that were related, in time and space, to either the formation of the unconformity or the deposition of the Martin Group or both.

Equilibrium and nonequilibrium many-body perturbation theory: a unified framework based on the Martin-Schwinger hierarchy

International Nuclear Information System (INIS)

Van Leeuwen, Robert; Stefanucci, Gianluca

2013-01-01

We present a unified framework for equilibrium and nonequilibrium many-body perturbation theory. The most general nonequilibrium many-body theory valid for general initial states is based on a time-contour originally introduced by Konstantinov and Perel'. The various other well-known formalisms of Keldysh, Matsubara and the zero-temperature formalism are then derived as special cases that arise under different assumptions. We further present a single simple proof of Wick's theorem that is at the same time valid in all these flavors of many-body theory. It arises simply as a solution of the equations of the Martin-Schwinger hierarchy for the noninteracting many-particle Green's function with appropriate boundary conditions. We further discuss a generalized Wick theorem for general initial states on the Keldysh contour and derive how the formalisms based on the Keldysh and Konstantinov-Perel'-contours are related for the case of general initial states.

The Bertlmann-Martin Inequality and Spin Degrees of Freedom

International Nuclear Information System (INIS)

Boufas, S.; Ighezou, F.-Z.; Lombard, R. J.

2012-01-01

The Bertlmann-Martin inequality based on the dipole sum rule is revisited taking into account the spin degrees of freedom. We consider 1 and 2 particles of spin 1/2 in a mean field, adding a spin dependent interaction. The derivation of the inequality relies on the closure relation. We discuss the effect of the Pauli principle, and the restrictions it imposes on the use of the closure relation. The problem is exemplified by a simple model based on harmonic forces. Moreover, in the 2 particle case, the model we use is separable in the relative and centre of mass coordinates. In this case, we show that for operators connecting only singlet states, their sum rule can be calculated in the usual way, i. e. via the double commutator of this operator with the Hamiltonian. An upper bound can also be obtained by using the Bertlmann-Martin technique. This is not possible for operators involving a transition between singlet and triplet states. (author)

Martin Van Butchell (1735-1814): the eccentric, "kook" dentist of old London.

Science.gov (United States)

Christen, A G; Christen, J A

1999-11-01

This article is a thumbnail sketch of the life and times of Martin Van Butchell (1735-1814), an eccentric, "kook" advertising dentist of Old London. Van Butchell earned these descriptive labels by displaying an unorthodox lifestyle, an outrageous personal appearance and outlandish, extreme and socially unacceptable personal and professional behaviors. While the general populace seemed to be fascinated by his strange ways, dentists and physicians were generally alienated by them. Nevertheless, he was considered a good dentist for his time, and he was extremely popular with his patients. Martin practiced dentistry for 23 years, and he practiced medicine as well, specializing in the treatment of ruptures and anal fistulas. Van Butchell interacted greatly with both John and William Hunter, who became two of the most famous and talented physicians, surgeons, anatomists and biologists of all time. When his first wife, Mary died, Martin arranged for her body to be embalmed and publicly displayed in his dental office for advertising purposes. Her preserved body was shown at the Museum of the Royal College of Surgeons (London), until it was destroyed by a German fire bomb in May, 1941. Mary's remains were on public display for a total of 166 years.

Recent advancements in robotic micro-optical assembly at the Lockheed Martin Optical Payload Center of Excellence

Science.gov (United States)

Hwang, David; Larson, Thomas M.

2017-08-01

Lockheed Martin Space Systems Company Optical Payloads Center of Excellence is in process of standing up the Robotic Optical Assembly System (ROAS) capability at Lockheed Martin Coherent Technologies in Colorado. This currently implemented Robotic Optical Assembly has enabled Lockheed Martin to create world-leading, ultra-lowSWAP photonic devices using a closed-loop control robot to precisely position and align micro-optics with a potential fill factor of >25 optics per square inch. This paper will discuss the anticipated applications and optical capability when ROAS is fully operational, as well as challenge the audience to update their "rules of thumb" and best practices when designing low-SWAP optical-mechanical systems that take advantage of Lockheed Martin's ROAS capability. This paper will reveal demonstrated optical pointing and stability performance achievable with ROAS and why we believe these optical specifications are relevant for the majority of anticipated applications. After a high level overview of the ROAS current state, this paper will focus in on recent results of the "Reworkable Micro-Optics Mounting IRAD". Results from this IRAD will correlate to the anticipated optical specifications required for relevant applications.

Price Theory and Money Coupled: some Remarks on the Ayres-Martinás Theory

Directory of Open Access Journals (Sweden)

Zsolt Gilanyi

2013-01-01

Full Text Available The main concern of economic science is to explain the Wealth of Nations. This tradition implies on the one hand, that wealth must be evaluated i.e.: economic science must elaborate a price theory; on the other hand, money should be integrated in economic theories because prices are expressed in monetary terms. Mainstream economic theory succeeds in price determination (with some limits but fails on money integration, while non-mainstream monetary models succeed on money integration but fail on price determination. In this paper I argue that the Ayres-Martinás theoretical framework is a promising tentative to cope with this challenge of economic science.

Fortissimus robore: Martin Krpan as a case of biblical reception

Directory of Open Access Journals (Sweden)

David Movrin

2009-12-01

Full Text Available Martin Krpan z Vrha, written by Fran Levstik as a conscious experiment in prose-writing, has been interpreted variously during the last century and a half. The duel between a Slovenian peasant and a giant who comes to terrorise Vienna was in turn read by scholars as a political satire, the realisation of a literary and linguistic programme, a literary parody etc. Its motif was mostly interpreted with reference to Slavic folklore characters (Pegam and Lambergar, Prince Marko,peter Klepec etc.. The analysis according to the model devised by Vladimir Propp, however, shows striking similarities with Biblical story of David and Goliath (1 Sm 17. The reception of this motif is marked by significant political overtones, already present in antiquity and then interest­ ingly developed in places as diverse as sixteenth-century Florence, Prague, and the Netherlands. As attested by the sources, Levstik used this motif several limes; to a certain extent he even identi­ fied with its hero.

Slovenian-Croatian boundary: backgrounds of boundary-making and boundary-breaking in Istria regarding the contemporary boundary dispute

Full Text Available Boundary-making in Istria is an old undertaking. It has actually never ceasesed, not even today. Istrian peninsula has thus undergone substantial boundary shifts during the last couple of centuries (especially after the Venetian demise in 1797. But Istria carries its worldwide fame also due to one of probably the harshest disputes on the post-war European grounds – the Trieste territory dispute. In author's perspective, this dispute is one of the four main corner-stones of the current Slovenian-Croatian boundary dispute. The remaining three include the Kozler's boundary around Dragonja (Rokava River, the ungraspable notions of Austrian censuses in Istria, and the narratives of partisan settlements on military jurisdiction. However, there are other very important aspects which significantly shaped the development of the dispute, but we will focus at assessing the importance of the aforementioned ones. In this sense, the analysis of the effects of the outcome of the Trieste dispute and its implications to the contemporary interstate dispute is set forth. By unveiling its material and consequently its psychological effects upon the contemporary bilateral relations, its analyses simultaneously reveals backgrounds of never answered question, why Kozler's proposed linguistic boundary around Dragonja (Rokava River turned out to become a boundary of national character. Though nowadays disputed, there is absolutely no chance for both involved parties to substantially draw away from once decisively drawn line of a layman. Despite the fierce battle of words in Slovenian public media on whether should the interstate boundary be placed on Mirna (Quieto or Dragonja Rivers, it will be argued here that the actual choice of the Valley of Dragonja as a boundary is by all means Slovenian. The arguments are based on extensive analyses of cartographic materials, relevant literature, documents, and statistical data.

Full Text Available El tratado clandestino Origo et fundamenta religionis christianae ataca los fundamentos del cristianismo y propone una religión natural. Pese a que todas las copias manuscritas que lo conservan datan del siglo xVIII, se encuentran suficientes indicios que señalan al silesio Martin Seidel como su autor y documentan la existencia del texto a finales del siglo xVI o principios del xVII. Las primeras fuentes sobre Seidel lo vinculan con los antitrinitarios de Heidelberg (1570, los unitarios polacos (1580 y los “cripto-socinianos” de Altdorf (1610. En este artículo valoro dichas fuentes y corrijo a la luz de las mismas algunas afirmaciones de la crítica reciente sobre Seidel y su Origo.

The Rufous Hummingbird in hovering flight -- full-body 3D immersed boundary simulation

Science.gov (United States)

Ferreira de Sousa, Paulo; Luo, Haoxiang; Bocanegra Evans, Humberto

2009-11-01

Hummingbirds are an interesting case study for the development of micro-air vehicles since they combine the high flight stability of insects with the low metabolic power per unit of body mass of bats, during hovering flight. In this study, simulations of a full-body hummingbird in hovering flight were performed at a Reynolds number around 3600. The simulations employ a versatile sharp-interface immersed boundary method recently enhanced at our lab that can treat thin membranes and solid bodies alike. Implemented on a Cartesian mesh, the numerical method allows us to capture the vortex dynamics of the wake accurately and efficiently. The whole-body simulation will allow us to clearly identify the three general patterns of flow velocity around the body of the hummingbird referred in Altshuler et al. (Exp Fluids 46 (5), 2009). One focus of the current study is to understand the interaction between the wakes of the two wings at the end of the upstroke, and how the tail actively defects the flow to contribute to pitch stability. Another focus of the study will be to identify the pair of unconnected loops underneath each wing.

Jean-Martin Charcot, father of modern neurology: an homage 120 years after his death

2013-10-01

Full Text Available Jean-Martin Charcot was a pioneer in a variety of subjects, including nervous system diseases; anatomy; physiology; pathology; and diseases of ageing, joints, and lungs. His medical achievements were mainly based on his anatomopathological proficiency, his observation, and his personal thoroughness that favored the delineation of the nosology of the main neurological diseases, including multiple sclerosis, amyotrophic lateral sclerosis, Parkinson’s disease, peroneal muscular atrophy, and hysteria/epilepsy. The link of this anatomoclinical method with iconographic representations and theatrical lessons, and the rich bibliographical documentations, carried out in a crowded diseased people barn - Salpetrière hospital were the basis of his achievements, which are still discussed 120 years after his death.

Social marketing and MARTIN: tools for organizing, analyzing, and interpreting qualitative data.

Science.gov (United States)

Higgins, J W

1998-11-01

The purpose of this article is to discuss how the computer software program MARTIN and social marketing concepts (understanding the consumer perspective, exchange, marketing mix, and segmentation) were used as organizational, analytical, and interpretive tools for qualitative data. The qualitative data are from a case study on citizen participation in a health reform policy in British Columbia. The concept of broad-based public participation is a fundamental element of health promotion and citizenship. There is a gap, however, between the promise and reality of citizen participation in health promotion. Emerging from the analysis was an understanding of the societal circumstances that inhibited or fostered participation. This article describes how the code-based, theory-building attributes of the MARTIN software facilitated a new conceptualization of participatory citizenship and generated new insights into understanding why some people participate and others do not.

A lower bound to (r) 1s is established from the Thomas-Reiche-Kuhn sum rule applied to the reduced equation for the s-states. It is linked to the average value of (r 2 ) 1s We discuss, on few examples, how the use of approximate value for (r 2 ) 1s , derived from the generalized Bertlmann and Martin inequalities, preserves the lower bound character of (r) 1s . Finally, by using the uncertainty principle and the uncertainty in the radial position, we derive a low bound to the ground state kinetic energy

Nuclear data uncertainties for local power densities in the Martin-Hoogenboom benchmark

International Nuclear Information System (INIS)

Van der Marck, S.C.; Rochman, D.A.

2013-01-01

The recently developed method of fast Total Monte Carlo to propagate nuclear data uncertainties was applied to the Martin-Hoogenboom benchmark. This Martin- Hoogenboom benchmark prescribes that one calculates local pin powers (of light water cooled reactor) with a statistical uncertainty lower than 1% everywhere. Here we report, for the first time, an estimate of the nuclear data uncertainties for these local pin powers. For each of the more than 6 million local power tallies, the uncertainty due to nuclear data uncertainties was calculated, based on random variation of data for 235 U, 238 U, 239 Pu and H in H 2 O thermal scattering. In the center of the core region, the nuclear data uncertainty is 0.9%. Towards the edges of the core, this uncertainty increases to roughly 3%. The nuclear data uncertainties have been shown to be larger than the statistical uncertainties that the benchmark prescribes

Stimmung e trascendenza. Il ruolo del pathos in Martin Heidegger

Directory of Open Access Journals (Sweden)

Elisa Zocchi

2017-04-01

Full Text Available This paper aims to investigate the significance of mood for a philosophical approach to emotion. Are moods problematic because they constrain us in an affective cage? Or do they rather give us access to the world? The starting point for this investigation is the work of Martin Heidegger: I analyze what he defines as vorweltlich (what comes before meaning arguing that this term refers to the emotional dimension of human existence, in particular, to mood, or, in Heideggerian terms, Stimmung. Human existence is not just a neutral being-there but a being-affected, a being-in-a-mood. I then move on to consider the role of mood in relation to the concept of transcendence, providing an analysis of two main source of inspiration in Heidegger’s thought: Augustine and Aristotle. This allows us to distinguish three aspects of Stimmung: Stimmung as openness to the world, Stimmung as teleological movement, and Stimmung as event of ontological difference. In the final section, I discuss the contribution of these aspects of Heidegger’s thought to the contemporary debate on emotions.

William Golding’s Apocalyptic Vision in Lord of the Flies and Pincher Martin

Directory of Open Access Journals (Sweden)

Chatterjee Arnab

2017-07-01

Full Text Available Humanity has long been haunted by the notions of Armageddon and the coming of a Golden Age. While the English Romantic poets like Shelley saw hopes of a new millennium in poems like “Queen Mab” and “The Revolt of Islam”, others like Blake developed their own unique “cosmology” in their longer poems that were nevertheless coloured with their vision of redemption and damnation. Even Hollywood movies, like The Book of Eli (2010, rehearse this theme of salvation in the face of imminent annihilation time and again. Keeping with such trends, this paper would like to trace this line of apocalyptic vision and subsequent hopes of renewal with reference to William Golding’s debut novel Lord of the Flies (1954 and his Pincher Martin (1956. While in the former, a group of young school boys indulge in violence, firstly for survival, and then for its own sake, in the latter, a lonely, shipwrecked survivor of a torpedoed destroyer clings to his own hard, rock-like ego that subsequently is a hurdle for his salvation and redemption, as he is motivated by a lust for life that makes him exist in a different moral and physical dimension. In Lord of the Flies, the entire action takes place with nuclear warfare presumably as its backdrop, while Pincher Martin has long been interpreted as an allegory of the Cold War and the resultant fear of annihilation from nuclear fallout (this applies to Golding’s debut novel as well. Thus, this paper would argue how Golding weaves his own vision of social, spiritual, and metaphysical dissolution, and hopes for redemption, if any, through these two novels.

The Kimber-Martin-Ryskin unintegrated partons via the MRST and GRV parametrizations

International Nuclear Information System (INIS)

Modarres, M.; Hosseinkhani, H.

2009-01-01

We consider the GRV98 (Glueck et al.) and MRST99 (Martin et al.) sets of parton distribution functions (PDFs) as the inputs to obtain the unintegrated PDFs (UPDFs) via the Kimber-Martin-Ryskin (KMR) procedure. The ratios of MRST99 to GRV98 for both PDFs and UPDFs are compared. Since UPDFs are two scales dependent functions (namely k t 2 and μ 2 ), by fixing the values of k t 2 or μ 2 , their relative behaviors for the wide range of μ 2 or k t 2 are investigated. It is shown that by increasing k t 2 the UPDFs are shifted toward the larger values of the scale μ 2 . Finally, it is observed that the KMR procedure is not only stable and insensitive to the variation of input sets of partons such as those of GRV or MRST, but also it has this ability to suppress these discrepancies to make the unique and reliable outputs for UPDFs

For the (non-axisymmetric) stellarator class of plasma confinement devices to be feasible candidates for fusion power stations it is essential that, to a good approximation, the magnetic field lines lie on nested flux surfaces; however, the inherent lack of a continuous symmetry implies that magnetic islands responsible for breaking the smooth topology of the flux surfaces are guaranteed to exist. Thus, the suppression of magnetic islands is a critical issue for stellarator design, particularly for small aspect ratio devices. Pfirsch-Schluter currents, diamagnetic currents, and resonant coil fields contribute to the formation of magnetic islands, and the challenge is to design the plasma and coils such that these effects cancel. Magnetic islands in free-boundary high-pressure full-current stellarator magnetohydrodynamic equilibria are suppressed using a procedure based on the Princeton Iterative Equilibrium Solver [Reiman and Greenside, Comp. Phys. Comm. 43 (1986) 157] which iterate s the equilibrium equations to obtain the plasma equilibrium. At each iteration, changes to a Fourier representation of the coil geometry are made to cancel resonant fields produced by the plasma. The changes are constrained to preserve certain measures of engineering acceptability and to preserve the stability of ideal kink modes. As the iterations continue, the coil geometry and the plasma simultaneously converge to an equilibrium in which the island content is negligible, the plasma is stable to ideal kink modes, and the coils satisfy engineering constraints. The method is applied to a candidate plasma and coil design for the National Compact Stellarator Experiment [Reiman, et al., Phys. Plasmas 8 (May 2001) 2083

2015-04-01

Gold mining is responsible for most Hg pollution in developing countries. The aims of this study were to assess the levels of total Hg (T-Hg) in human hair, fish, water, macrophyte, and sediment samples in the gold mining district of San Martin de Loba, Colombia, as well as to determine fish consumption-based risks for T-Hg ingestion. T-Hg levels were measured by electrothermal atomization and atomic absorption spectroscopy. The overall mean T-Hg level in hair for humans in the mining district of San Martin de Loba was 2.12 μg/g, whereas for the reference site, Chimichagua, Cesar, it was 0.58 μg/g. Mean T-Hg levels were not different when considered within localities belonging to the mining district but differed when the comparison included Chimichagua. T-Hg levels in examined locations were weakly but significantly associated with age and height, as well as with fish consumption, except in San Martin de Loba. High T-Hg concentrations in fish were detected in Pseudoplatystoma magdaleniatum, Caquetaia kraussii, Ageneiosus pardalis, Cyrtocharax magdalenae, and Triportheus magdalenae, whereas the lowest appeared in Prochilodus magdalenae and Hemiancistrus wilsoni. In terms of Hg exposure due to fish consumption, only these last two species offer some guarantee of low risk for Hg-related health problems. Water, floating macrophytes, and sediments from effluents near mining sites also had high Hg values. In mines of San Martin de Loba and Hatillo de Loba, for instance, the geoaccumulation index (I(geo)) for sediments reached values greater than 6, indicating extreme pollution. In short, these data support the presence of a high Hg-polluted environment in this mining district, with direct risk for deleterious effects on the health of the mining communities.

Full Text Available The history of the green fluorescent protein (GFP starts with Osamu Shimomura at the beginning of the 1960s, with his discovery from the extracts of the Aequorea victoria jellyfish. However, it is not until the beginning of the 1990s, that the neurobiologist Martin Chalfie, applying genetic engineering tech- niques, achieved for the first time the heterology expression of the GFP in prokaryotes (E. coli and eukaryotes (Caernohabditis elegans, from a clone of the jellyfish’s gen that codifies the GFP prepared by Douglas Prasher. Besides fluorescing in green, the results from this work also demonstrated that it does not require any other cofactor or enzyme of the jellyfish for its expression or for the own forming of a fluorophore. At the same time, Chalfie proposed that the GFP could be used for the marking of cells on living ani- mals or the tag of proteins. Based upon these results, many scientists started working on research related to the GFP; actually this protein is used on different fields such as biotechnol- ogy, development biology, environmental chemistry and medicine. In the case of the latter, it has helped to elucidate the cellular mechanisms from which diseases are made of. Science owes Roger Tsien, amongst other contributions, the creation of differ- ent mutations of the GFP.La historia de la proteína verde fluorescente (GFP se inicia con Osamu Shimomura a principios de la década de 1960, con su descubrimiento de esta proteína a partir de extractos de la medusa Aequorea victoria.

Brain response to prosodic boundary cues depends on boundary position

Directory of Open Access Journals (Sweden)

Julia eHolzgrefe

2013-07-01

Full Text Available Prosodic information is crucial for spoken language comprehension and especially for syntactic parsing, because prosodic cues guide the hearer’s syntactic analysis. The time course and mechanisms of this interplay of prosody and syntax are not yet well understood. In particular, there is an ongoing debate whether local prosodic cues are taken into account automatically or whether they are processed in relation to the global prosodic context in which they appear. The present study explores whether the perception of a prosodic boundary is affected by its position within an utterance. In an event-related potential (ERP study we tested if the brain response evoked by the prosodic boundary differs when the boundary occurs early in a list of three names connected by conjunctions (i.e., after the first name as compared to later in the utterance (i.e., after the second name. A closure positive shift (CPS — marking the processing of a prosodic phrase boundary — was elicited only for stimuli with a late boundary, but not for stimuli with an early boundary. This result is further evidence for an immediate integration of prosodic information into the parsing of an utterance. In addition, it shows that the processing of prosodic boundary cues depends on the previously processed information from the preceding prosodic context.

Boundary organizations to boundary chains: Prospects for advancing climate science application

Directory of Open Access Journals (Sweden)

Christine J. Kirchhoff

2015-01-01

Full Text Available Adapting to climate change requires the production and use of climate information to inform adaptation decisions. By facilitating sustained interaction between science producers, boundary organizations narrow the gap between science and decision-making and foster the co-production of actionable knowledge. While traditional boundary organization approaches focused on intense one-on-one interactions between producers and users increases usability, this approach requires significant time and resources. Forming “boundary chains”, linking complimentary boundary organizations together, may reduce those costs. In this paper, we use longitudinal observations of a boundary chain, interviews and surveys to explore: (1 how producer-user interactions increase understanding and information usability and (2 if and how efficiencies in climate information production, dissemination and use arise as a result of the boundary chain. We find that forming and sustaining an effective boundary chain requires not only interest, commitment and investment from every link in the chain but also a level of non-overlapping mutual dependency and complementary skill sets. In this case, GLISA’s strength in producing scientific information and their credibility as climate scientists and HRWC’s strengths in facilitation, connection with potential information users, and their recognition and reputation in the watershed add value to the boundary chain enabling the boundary chain to accomplish more with greater efficiency than if each organization in the chain tried to work independently. Finally, data show how the boundary chain increased efficiencies in educating potential users about the strengths and limitations of climate science and improving the production, dissemination, and use of climate information.

Geological and radiometric study of the anomaly ''San Martin'' municipality of Sierra Mojada, Coahuila

1975-01-01

When it first became known that there were uranium ores at the mine known as San Martin (72 hectares, Mining Agency, Sabinas, Mexico), exploration work was started with the sinking of two wells at the sites of maximum radiometric intensity. A short while afterwards, however, this work was suspended. In 1974, the work required for evaluation of the locality was begun. Geological and radiometric studies carried out both at the surface and underground pointed to the conclusion that the San Martin anomaly, down to the depth explored (40 metres), is a stockwork-type deposit or a tabular seam of the fissure type. It was concluded that in view of the grades obtained (0.0227%U 3 O 6 ) down to 40 metres, the deposit cannot be considered of econimic importance at the present time. (author)

First technoscience, then cyberscience, transform the human epistemic adventure in a risk and uncertainty factor for the survival of the species. The knowledge-power equivalence adds artificial vulnerability to natural vulnerability.

Solution of a Problem Linear Plane Elasticity with Mixed Boundary Conditions by the Method of Boundary Integrals

Directory of Open Access Journals (Sweden)

Nahed S. Hussein

2014-01-01

Full Text Available A numerical boundary integral scheme is proposed for the solution to the system of …eld equations of plane. The stresses are prescribed on one-half of the circle, while the displacements are given. The considered problem with mixed boundary conditions in the circle is replaced by two problems with homogeneous boundary conditions, one of each type, having a common solution. The equations are reduced to a system of boundary integral equations, which is then discretized in the usual way, and the problem at this stage is reduced to the solution to a rectangular linear system of algebraic equations. The unknowns in this system of equations are the boundary values of four harmonic functions which define the full elastic solution and the unknown boundary values of stresses or displacements on proper parts of the boundary. On the basis of the obtained results, it is inferred that a stress component has a singularity at each of the two separation points, thought to be of logarithmic type. The results are discussed and boundary plots are given. We have also calculated the unknown functions in the bulk directly from the given boundary conditions using the boundary collocation method. The obtained results in the bulk are discussed and three-dimensional plots are given. A tentative form for the singular solution is proposed and the corresponding singular stresses and displacements are plotted in the bulk. The form of the singular tangential stress is seen to be compatible with the boundary values obtained earlier. The efficiency of the used numerical schemes is discussed.

The Spectacle of Redemption: Guilt and Violence in Martin Scorsese’s Raging Bull

Directory of Open Access Journals (Sweden)

Arturo Serrano

2015-06-01

Full Text Available Of all the characters that undertake a search for redemption in Martin Scorsese’s films, perhaps it is the story of Jake La Motta in Raging Bull that for many reasons presents the greatest challenge to understanding redemption’s role in the narratives of his films. Is Jake La Motta a redeemed character at the end of Raging Bull? I argue that Scorsese uses Raging Bull to criticize a ritualistic view of redemption by portraying the beginning of Jake’s search as a futile attempt to submit himself to a public spectacle of ritual violence in the boxing ring while visually relating this to the Catholic sacraments and the crucifixion. It will only be later—in the loneliness of a jail cell, estranged from his family and without having to have had gone through a rite—that Jake achieves the self-awareness redemption requires.

On a Kubo-Martin-Schwinger state of the Sine-Gordon system

International Nuclear Information System (INIS)

Peskov, N.V.

1986-01-01

This paper considers the Sine-Gordon equation on a finite interval as a Hamiltonian system. A Gaussian measure is defined on an extension of the phase space. It is shown that the partition funciton Z employed in the statistical mechanics of the solitons is an integral with respect to this measure. An algebra of observables is defined and on it a state is constructed which satisfies the Kubo-Martin-Schwinger condition

The article substantiates the possibility of building full parametric analytical solutions of mathematical physics problems in arbitrary regions by means of computer systems. The suggested effective means for such solutions is the method of boundary states with perturbations, which aptly incorporates all parameters of an orthotropic medium in a general solution. We performed check calculations of elastic fields of an anisotropic rectangular region (test and calculation problems) for a generalized plane stress state.

2012-02-01

Full Text Available In this paper, we study the existence and multiplicity of positive solutions of a class of nonlinear fractional boundary value problems with  Dirichlet boundary conditions. By applying the fixed point theory on cones we establish a series of criteria for the existence of one, two, any arbitrary finite number, and an infinite number of positive solutions. A criterion for the nonexistence of positive solutions is also derived. Several examples are given for demonstration.

Ornamental “borderlands”: Elisabeth Wilson and Martin Heydrich’s historiographies of “primitive” ornament

Directory of Open Access Journals (Sweden)

Priyanka Basu

2015-06-01

Full Text Available This article examines texts by Elisabeth Wilson and Martin Heydrich written in 1914 at the University of Leipzig on the subject of ‘primitive’ ornament. Both synopsize the history and literature of this field from its beginnings in the nineteenth century to the time of their writing. This article considers how Wilson and Heydrich represent this history and how the field’s multidisciplinary practitioners perceived its pressing problems. Above all, Wilson and Heydrich set up a number of recurring oppositions between major approaches to ‘primitive’ art and ornament, between ‘materialist’ interpretation, allied with archaeology, symbolic interpretation practiced for the most part by ethnologists, and an ‘aesthetic’ approach, pursued by art theorists and focused on the psychological will of its creators. These issues and this configuration of approaches are further examined in one of August Schmarsow’s important essays on art history and ethnology.

Obituary: Martin F. McCarthy (1923-2010)

Science.gov (United States)

Coyne, George; Rubin, Vera

2011-12-01

Martin F. McCarthy, S.J., astronomer at the Vatican Observatory from 1958 until his retirement in 1999, died peacefully on 5 February at the age of 86 years at the Jesuit Campion Health Center in Weston, Massachusetts where he had resided since his retirement. McCarthy received his doctorate in astronomy from Georgetown University, Washington, DC in 1951. The study of carbon stars, stars whose atmospheres contain more carbon than oxygen, was a major interest for McCarthy. Carbon stars were originally discovered and studied in the 1860s by Fr. Secchi, the eminent Jesuit astronomer. Interestingly, Fr. Secchi spent 1848-50 at Georgetown University in Washington, where Martin McCarthy would receive his PhD degree 101 years later. Upon completion of his seminary studies in theology, he carried out post-doctoral research at Warner and Swasey Observatory, Lick Observatory, the Dominion Astrophysical Observatory and Yerkes Observatory until he began his career at the Vatican Observatory where he served as a key figure in the Observatory's transition to the world of modern research. He also brought the Observatory onto the international stage through his collaborations in research at, among other institutes, Palomar Observatory, Lowell Observatory, Las Campanas Observatories, the Cerro Tololo Interamerican Observatory and the Carnegie Institute of Washington. He served on the Executive Council of the Italian Astronomical Society (1969-1971), was chair of the National Committee of the Vatican to the International Astronomical Union (IAU) from 1979 until his retirement and was President of IAU Commission 25 Stellar Photometry and Polarimetry (1976-1979). During his career he published more than 120 research papers. He was a natural teacher, who enjoyed explaining and talking science to students and visitors. Among his many contributions to the growth of the Vatican Observatory, he was responsible in 1986 for the beginning of the series of the Vatican Observatory Summer

Full Text Available Martin Stannard is Professor of Modern English Literature at the University of Leicester. He read for his first degree in English at Warwick (1967-70, before taking an MA at Sussex University, and a DPhil at Oxford. Professor Stannard’s two-volume literary biography of Evelyn Waugh (1986, 1992, and his biography of Muriel Spark (2009 are essential reading for Waugh and Spark scholars, and are each studies in the value of historical contextualisation for appreciating the literary oeuvre of a writer. Stannard’s 1995 Norton Critical Edition of Ford Madox Ford’s modernist novel, The Good Soldier, similarly brings context to bear through his rigorous textual editing, annotation and critical apparatus. Stannard is currently the Principal Investigator for the Complete Works of Evelyn Waugh project, which is supported by a grant of  £822,000 from the AHRC, and which will see Oxford University Press publish 43 scholarly edition volumes of Waugh – the first of which appears next year. This year marks the fiftieth anniversary of Waugh’s death. Dr Barbara Cooke also teaches at the School of English at the University of Leicester. She received a BA and MA from Warwick (dates, and a PhD in Creative and Critical writing from the University of East Anglia for her interdisciplinary thesis Oil Men: the Twinned Lives of Arnold Wilson and Morris Young.

Entanglement properties of boundary state and thermalization

Guo, Wu-zhong

2018-06-01

We discuss the regularized boundary state {e}^{-{τ}_0H}\\Big|{.B>}_a on two aspects in both 2D CFT and higher dimensional free field theory. One is its entanglement and correlation properties, which exhibit exponential decay in 2D CFT, the parameter 1 /τ 0 works as a mass scale. The other concerns with its time evolution, i.e., {e}^{-itH}{e}^{-{τ}_0H}\\Big|{.B>}_a . We investigate the Kubo-Martin-Schwinger (KMS) condition on correlation function of local operators to detect the thermal properties. Interestingly we find the correlation functions in the initial state {e}^{-{τ}_0H}\\Big|{.B>}_a also partially satisfy the KMS condition. In the limit t → ∞, the correlators will exactly satisfy the KMS condition. We generally analyse quantum quench by a pure state and obtain some constraints on the possible form of 2-point correlation function in the initial state if assuming they satisfies KMS condition in the final state. As a byproduct we find in an large τ 0 limit the thermal property of 2-point function in {e}^{-{τ}_0H}\\Big|{.B>}_a also appears.

MARTINS: A foam/film flow model for molten material relocation in HWRs with U-Al-fueled multi-tube assemblies

International Nuclear Information System (INIS)

Kalimullah.

1994-01-01

Some special purpose heavy-water reactors (EM) are made of assemblies consisting of a number of coaxial aluminum-clad U-Al alloy fuel tubes and an outer Al sleeve surrounding the fuel tubes. The heavy water coolant flows in the annular gaps between the circular tubes. Analysis of severe accidents in such reactors requires a model for predicting the behavior of the fuel tubes as they melt and disrupt. This paper describes a detailed, mechanistic model for fuel tube heatup, melting, freezing, and molten material relocation, called MARTINS (Melting and Relocation of Tubes in Nuclear subassembly). The paper presents the modeling of the phenomena in MARTINS, and an application of the model to analysis of a reactivity insertion accident. Some models are being developed to compute gradual downward relocation of molten material at decay-heat power levels via candling along intact tubes, neglecting coolant vapor hydrodynamic forces on molten material. These models are inadequate for high power accident sequences involving significant hydrodynamic forces. These forces are included in MARTINS

Nonlinear Elliptic Boundary Value Problems at Resonance with Nonlinear Wentzell Boundary Conditions

Directory of Open Access Journals (Sweden)

Ciprian G. Gal

2017-01-01

Full Text Available Given a bounded domain Ω⊂RN with a Lipschitz boundary ∂Ω and p,q∈(1,+∞, we consider the quasilinear elliptic equation -Δpu+α1u=f in Ω complemented with the generalized Wentzell-Robin type boundary conditions of the form bx∇up-2∂nu-ρbxΔq,Γu+α2u=g on ∂Ω. In the first part of the article, we give necessary and sufficient conditions in terms of the given functions f, g and the nonlinearities α1, α2, for the solvability of the above nonlinear elliptic boundary value problems with the nonlinear boundary conditions. In other words, we establish a sort of “nonlinear Fredholm alternative” for our problem which extends the corresponding Landesman and Lazer result for elliptic problems with linear homogeneous boundary conditions. In the second part, we give some additional results on existence and uniqueness and we study the regularity of the weak solutions for these classes of nonlinear problems. More precisely, we show some global a priori estimates for these weak solutions in an L∞-setting.

Quantum “violation” of Dirichlet boundary condition

Directory of Open Access Journals (Sweden)

I.Y. Park

2017-02-01

Full Text Available Dirichlet boundary conditions have been widely used in general relativity. They seem at odds with the holographic property of gravity simply because a boundary configuration can be varying and dynamic instead of dying out as required by the conditions. In this work we report what should be a tension between the Dirichlet boundary conditions and quantum gravitational effects, and show that a quantum-corrected black hole solution of the 1PI action no longer obeys, in the naive manner one may expect, the Dirichlet boundary conditions imposed at the classical level. We attribute the ‘violation’ of the Dirichlet boundary conditions to a certain mechanism of the information storage on the boundary.

Full Text Available Background: Considering current demographic trends in society, education of seniors has become real needs and a challenge for the field of education and training institutions. Universities of the Third Age (UTA represent one option for senior education allowing them to study various fields at university level. Within UTA studies, the seniors are interested in studying mainly the issues of health and disease, aging and the social and legal issues. Seniors represent a group of students with specific educational needs. In teaching them it is therefore important to choose teaching methods that take account of developmental changes of the period, contain elements of clearness, and provide the space for communication and activity with the use of previous experiences of seniors. In the framework of elderly education at the UTA at Jessenius Faculty of Medicine in Martin (JFM CU the simulation methods are also used that bring elements of clarity and attractiveness into the teaching and serve to bridge theoretical education and practical training. Objective: The aim of the study was to determine the UTA senior students’ views on the use of simulation models and simulations in education and to find out what is their satisfaction with the training in the Simulation Center at JFM CU in Martin. Methods: Questionnaire of own construction was used to gather empirical data. The study involved 30 senior students of the third year of studies in the program “Elderly Care”, out of which 25 were women and 5 men. The average age of respondents was 67.3 years (SD 5.6. Results: Within education and training in Simulation Center, the seniors most positively evaluated preparedness, presentation and interpretation of the lecturer (4.96 and the way in which information were administered (4.76. They had the opportunity of hands-on work with the simulation models and practical training of their skills and such experience was evaluated as excellent (4.70. Seniors also

Healing relationships and the existential philosophy of Martin Buber

Directory of Open Access Journals (Sweden)

Stange Kurt C

2009-08-01

Full Text Available Abstract The dominant unspoken philosophical basis of medical care in the United States is a form of Cartesian reductionism that views the body as a machine and medical professionals as technicians whose job is to repair that machine. The purpose of this paper is to advocate for an alternative philosophy of medicine based on the concept of healing relationships between clinicians and patients. This is accomplished first by exploring the ethical and philosophical work of Pellegrino and Thomasma and then by connecting Martin Buber's philosophical work on the nature of relationships to an empirically derived model of the medical healing relationship. The Healing Relationship Model was developed by the authors through qualitative analysis of interviews of physicians and patients. Clinician-patient healing relationships are a special form of what Buber calls I-Thou relationships, characterized by dialog and mutuality, but a mutuality limited by the inherent asymmetry of the clinician-patient relationship. The Healing Relationship Model identifies three processes necessary for such relationships to develop and be sustained: Valuing, Appreciating Power and Abiding. We explore in detail how these processes, as well as other components of the model resonate with Buber's concepts of I-Thou and I-It relationships. The resulting combined conceptual model illuminates the wholeness underlying the dual roles of clinicians as healers and providers of technical biomedicine. On the basis of our analysis, we argue that health care should be focused on healing, with I-Thou relationships at its core.

Racism and the older voter? Arizona's rejection of a paid holiday to honor Martin Luther King.

Science.gov (United States)

Kastenbaum, R

1991-01-01

Two propositions that would have established a paid Martin Luther King holiday were defeated in Arizona's statewide elections of November 6, 1990. Communities and counties with high proportions of senior adult voters cast proportionately more votes against these propositions. Was this an example of racism among the primarily anglo senior adult voters of Arizona? Three models were proposed to account for the general pattern of election-related behavior as well as the vote itself: 1) proactive racist, 2) pragmatic self-interest, and 3) fortress mentality. It was suggested that proactive racism and pragmatic self-interest accounted for less of the opposition to a paid holiday honoring Martin Luther King than did a fortress mentality that has developed through a combination of circumstances. Attention is also given to the larger question of senior adults as perpetrators as well as victims of bigotry.

DOSEXPRT: A bioassay dosimetry code for Martin Marietta Energy Systems, Inc.

Energy Technology Data Exchange (ETDEWEB)

Ward, R.C.; Eckerman, K.F.

1992-04-01

The bioassay code DOSEXPRT was developed for Martin Marietta Energy Systems, Inc., to provide compliance with Department of Energy (DOE) Order 5480, Chapter 11. DOSEXPRT computes the intake of a radionuclide in any year (considering both acute and chronic intakes) from in vivo measurements of the retained activity and/or measurements of the activity in excreta. The committed effective and organ doses for the intake are computed as well as the effective and organ doses expected to be received in each calendar year out to 50 years beyond the year of intake. The bioassay records used as input for DOSEXPRT are extracted from the Martin Marietta Energy Systems Occupational Health Information System (OHIS). DOSEXPRT implements a set of algorithms with parameters governing the translocation, retention, and excretion of the nuclide contained in data files specific to the nuclide. These files also contain dose-per-unit-intake coefficients used to compute the committed dose equivalent for the intakes in the year. Annual organ and effective doses are computed using additional dose-rate files that contain data on the dose rate at various times following a unit intake. If measurements are presented for more than one assay for a given nuclide, DOSEXPRT estimates the intake by applying weights assigned in the nuclide file for each assay. DOSEXPRT is accessed off the OHIS MENU No. 4 and designed to be run as a batch processor, but can also be run interactively for testing purposes.

Rearranging social space: Boundary-making and boundary-work in a joint forest management project, Andhra Pradesh, India

Directory of Open Access Journals (Sweden)

Saito-Jensen Moeko

2010-01-01

Full Text Available Since the 1990s, there has been an increasing trend in developing countries to shift from state driven approaches to Community-based Natural Resource Management (CBNRM. In order to ensure sustainability of resources, the need for creating and maintaining clear resource use boundaries has been emphasised, both theoretically and in practice. However, there has been less attention to the varied social consequences for involved villages (whose inhabitants can access resources within the new boundaries and for excluded villages (whose inhabitants are prevented from accessing resources due to these boundaries. Drawing on a case study of three villages affected by the Joint Forest Management project in Andhra Pradesh, India, this article shows how resource use boundaries interact with social categories such as caste, gender and livelihood occupation in ways that facilitate asymmetric distribution of costs and benefits among local people. The article calls for more consultative processes in constituting new resources use boundaries and for flexible interventions to reconcile conflicts arising from boundary-making.

Rotor blade boundary layer measurement hardware feasibility demonstration

Science.gov (United States)

Clark, D. R.; Lawton, T. D.

1972-01-01

A traverse mechanism which allows the measurement of the three dimensional boundary layers on a helicopter rotor blade has been built and tested on a full scale rotor to full scale conditions producing centrifugal accelerations in excess of 400 g and Mach numbers of 0.6 and above. Boundary layer velocity profiles have been measured over a range of rotor speeds and blade collective pitch angles. A pressure scanning switch and transducer were also tested on the full scale rotor and found to be insensitive to centrifugal effects within the normal main rotor operating range. The demonstration of the capability to measure boundary layer behavior on helicopter rotor blades represents the first step toward obtaining, in the rotating system, data of a quality comparable to that already existing for flows in the fixed system.

Squares of White Noise, SL(2,C) and Kubo - Martin -Schwinger States

OpenAIRE

Prokhorenko, D. V.

2007-01-01

We investigate the structure of Kubo - Martin - Schwinger (KMS) states on some extension of the universal enveloping algebra of SL(2,C}. We find that there exists a one-to-one correspondence between the set of all covariant KMS states on this algebra and the set of all probability measures d\\mu on the real half-line, which decrease faster than any inverse polynomial. This problem is connected to the problem of KMS states on square of white noise algebra.

Boundary Hamiltonian Theory for Gapped Topological Orders

Science.gov (United States)

Hu, Yuting; Wan, Yidun; Wu, Yong-Shi

2017-06-01

We report our systematic construction of the lattice Hamiltonian model of topological orders on open surfaces, with explicit boundary terms. We do this mainly for the Levin-Wen string-net model. The full Hamiltonian in our approach yields a topologically protected, gapped energy spectrum, with the corresponding wave functions robust under topology-preserving transformations of the lattice of the system. We explicitly present the wavefunctions of the ground states and boundary elementary excitations. The creation and hopping operators of boundary quasi-particles are constructed. It is found that given a bulk topological order, the gapped boundary conditions are classified by Frobenius algebras in its input data. Emergent topological properties of the ground states and boundary excitations are characterized by (bi-) modules over Frobenius algebras.

On broadening the cognitive, motivational, and sociostructural scope of theorizing about gender development and functioning: comment on Martin, Ruble, and Szkrybalo (2002).

Science.gov (United States)

Bandura, Albert; Bussey, Kay

2004-09-01

In their article on gender development, C. L. Martin, D. N. Ruble, and J. Szkrybalo (see record 2002-18663-003) contrasted their conception of gender development with that of social cognitive theory. The authors of this commentary correct misrepresentations of social cognitive theory and analyze the conceptual and empirical status of Martin et al.'s (2002) theory that gender stereotype matching is the main motivating force of gender development. Martin et al. (2002) based their claim for the causal primacy of gender self-categorization on construal of gender discrimination as rudimentary self-identity, equivocal empirical evidence, and dismissal of discordant evidence because of methodological deficiencies. The repeated finding that gendered preferences and behavior precede emergence of a sense of self is discordant with their theory. Different lines of evidence confirm that gender development and functioning are socially situated, richly contextualized, and conditionally manifested rather than governed mainly by an intrinsic drive to match stereotypic gender self-conception.

The new investigation of Kimber-Martin-Ryskin unintegrated partons

International Nuclear Information System (INIS)

Modarres, M.; Hosseinkhani, H.

2010-01-01

The three sets of conventional integrated parton distribution functions (PDFs) such as MSTW 2008 (Martin et al), GJR08 (Glueck et al) and Coquet.6 (Nadol sky et al) are used as the inputs to generate the unintegrated parton distribution functions (U PDFs) via the Kimber-Martin-Ryskin (Kmr) procedure and the results are compared with each other. The U PDFs are obtained for several values of the squared transverse momentum component of parton (k t 2 ) and the longitudinal momentum fraction (x). The various aspects of the PDFs and the U PDFs ratios of GJR08 and CTEQ6.6 to MSTW 2008 are analyzed and discussed. In addition to our previous justification (Modarres and Hosseinkani in Nucl Phys A 815:40, 2009) about the stability and the reliability of KMR UPDFs, it is observed here that they are more convergent in the larger values of the scale k t 2 (i.e. the suppression of discrepancies of different PDFs schemes) such that the UPDFs produced via the KMR approach are stable with respect to the variation of the input sets of PDFs and they also tend to a unique value by increasing the scale k t 2 . As the final justifications and conclusions, it seems that the UPDFs produced via the KMR prescription are sufficiently reliable to use in the related phenomenological computations. Our investigation is based on the comparison of the generated UPDFs via the KMR approach by using the MSTW2008, the G J R and the CT Eq.6 sets of the conventional integrated partons as inputs. It is carried out by comparing the ratios G J R/MSTW2008 and CT Eq.6/MSTW2008 and analyzing the results. Although all the UPDFs are well behaved and applicable, but at the higher transverse momentum k 2 t the results are considerable. The most convergent and the unique UPDFs are for the gluon distributions which are noticeably good. (author)

We study boundary scattering in the ϕ{sup 4} model on a half-line with a one-parameter family of Neumann-type boundary conditions. A rich variety of phenomena is observed, which extends previously-studied behaviour on the full line to include regimes of near-elastic scattering, the restoration of a missing scattering window, and the creation of a kink or oscillon through the collision-induced decay of a metastable boundary state. We also study the decay of the vibrational boundary mode, and explore different scenarios for its relaxation and for the creation of kinks.

BSLIC: SLIC Superpixels Based on Boundary Term

Directory of Open Access Journals (Sweden)

Hai Wang

2017-02-01

Full Text Available A modified method for better superpixel generation based on simple linear iterative clustering (SLIC is presented and named BSLIC in this paper. By initializing cluster centers in hexagon distribution and performing k-means clustering in a limited region, the generated superpixels are shaped into regular and compact hexagons. The additional cluster centers are initialized as edge pixels to improve boundary adherence, which is further promoted by incorporating the boundary term into the distance calculation of the k-means clustering. Berkeley Segmentation Dataset BSDS500 is used to qualitatively and quantitatively evaluate the proposed BSLIC method. Experimental results show that BSLIC achieves an excellent compromise between boundary adherence and regularity of size and shape. In comparison with SLIC, the boundary adherence of BSLIC is increased by at most 12.43% for boundary recall and 3.51% for under segmentation error.

Lionfish (Pterois spp.) are invasive species that have recently spread throughout the Caribbean. Lionfish are available for purchase in local markets for human consumption in several islands of the region. We examined the prevalence of ciguatoxins (CTXs) in lionfish from the French Antilles, a ciguatera-endemic region. The neuroblastoma-2a (N2a) cell assay was used to assess composite cytotoxicity in 120 fish samples collected from the surrounding waters of Guadeloupe (n = 60), Saint Barthélemy Islands (n = 55) and Saint Martin (n = 5). Twenty-seven of these samples exhibited CTX-like activity by the N2a assay. Ciguatoxin (CTX) was confirmed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in multiple samples that presented highest composite toxicity levels by N2a. Those fish found to contain CTXs were all from Saint Barthélemy. Lionfish from Guadeloupe and Saint Martin did not exhibit toxin activity, although the sample size from Saint Martin was insufficient to draw any conclusions as to the incidence of CTXs. In this study, we provide information about the potential hazard of ciguatera associated with the consumption of lionfish from known endemic areas. We also demonstrate the utility of the cell-based assay combined with LC-MS/MS to assess activity and to provide structural confirmation of CTXs respectively. Copyright © 2015 Elsevier Ltd.

It can be concluded on the basis of a more precise analysis that quite unjustified and in principle incorrect physical results are obtained if the equations are used outside this region, i.e., for |t|approx-gt 0.15 GeV 2 . copyright 1997 The American Physical Society

The Hand with the Pen: Martin of Loka, Matjaž Jurčič of Kapela and Herman Talner of Trebnje and their Colophons

Full Text Available Beginning with expressions such as ideographs, the author’s autograph, and the copyist’s autograph, this paper explains the dilemma of some Late Medieval Manuscripts in Slovenian collections that were mistakenly identified as being the author’s own textual creation. The main part of this paper focuses on three mid-15th-century copyists: Martin of Loka, Matjaž Jurčič of Kapela, and Herman Talner of Trebnje. Because each of them added the name of their hometown to their signature, all three can be recognized as hailing from Slovenian places. Martin of (Škofja Loka was an erudite man, and this is evident from his texts he wrote in German, Slovenian and Latin, as well as from his many forms of scripts. Matjaž Jurčič of Kapela was probably a freelance artist, and the colophon to his copy of an epic poem contains an inscription in Latin, German and Provençal. Working in a remote location, the third, Herman Talner, copied a lengthy politically-oriented poem for Lord Ludvik of Castle Kozjak. At the end of their work all three added colophons which provide valuable information about these individuals and the conditions in which they worked.

In order to face the challenges in healthcare this century, it is essential that surgeons understand modern leadership principles. One of the greatest leaders in history was Dr. Martin Luther King, Jr., who provides a shining example of level-5 leadership for us to study. The study of leadership principles of great leaders can provide us with practical methods of conflict resolution as well as inspiration to keep us engaged and focused. As leaders of the medical community, we face numerous challenges, including discovering and implementing new treatments for disease, providing care for the indigent, overcoming educational challenges such as incorporating the ACGME Core Competencies into our surgical training and promoting diversity in education. Achieving these goals is often hindered by the environment in which we labor-nearly 50 million are uninsured, the rising cost of medical care is currently at 16% of the GNP, and reimbursement rates are falling-which makes the practice of surgery a significant challenge. Effective leadership will be paramount in achieving these goals. In this editorial, which summarizes a presentation given to the Surgical Section of the annual National Medical Association meeting, five important leadership principles that are important for surgeons have been selected and related to the outstanding leadership of Dr. Martin Luther King, Jr.

The very personal touch of Professor Martin Gibbs as a worldwide advocate for photosynthesis and plant physiology was lost with his death in July 2006. Widely known for his engaging humorous personality and his humanitarian lifestyle, Martin Gibbs excelled as a strong international science diplomat; like a personal science family patriarch encouraging science and plant scientists around the world. Immediately after World War II he was a pioneer at the Brookhaven National Laboratory in the use of (14)C to elucidate carbon flow in metabolism and particularly carbon pathways in photosynthesis. His leadership on carbon metabolism and photosynthesis extended for four decades of working in collaboration with a host of students and colleagues. In 1962, he was selected as the Editor-in-Chief of Plant Physiology. That appointment initiated 3 decades of strong directional influences by Gibbs on plant research and photosynthesis. Plant Physiology became and remains a premier source of new knowledge about the vital and primary roles of plants in earth's environmental history and the energetics of our green-blue planet. His leadership and charismatic humanitarian character became the quintessence of excellence worldwide. Martin Gibbs was in every sense the personification of a model mentor not only for scientists but also shown in devotion to family. Here we pay tribute and honor to an exemplary humanistic mentor, Martin Gibbs.

Mercury (Hg) is a heavy metal, considered a highly toxic pollutant. In its elemental state is volatile, making it easy to transport over long distances through the atmosphere, so that environmental pollution caused by it is a serious problem worldwide. Activities such as gold mining, where metallic Hg is used, have contributed with its global distribution, affecting ecosystems and human health. The aim of this study was to determine the levels of total mercury (T-Hg) in air in gold mining areas in Southern Bolivar, particularly in the mining district of San Martin de Loba, in the municipalities of San Martin de Loba and Barranco de Loba (Mina Santa Cruz), Colombia. In situ analyses were performed by atomic absorption spectroscopy, using a portable Ra-915 + Zeeman mercury analyzer. In Mina Santa Cruz, one of the most important gold mines in Colombia, concentrations of Hg in air ranged between 163.7 ± 6.6 and 40 455 ± 2154 mg/m{sup 3}, while in the urban area of San Martin de Loba varied from 223.6 ± 20.8 to 27 140 ± 212.5 ng/m{sup 3}. In those places where an amalgam burning process was taking place at the time of the measurements, Hg concentrations reached values of 40 455 ± 2154 ng/m{sup 3}. These data imply a severe occupational exposure to Hg for operators and citizens living in cities located near mines. Therefore, it is important to regulate and control the use of Hg in gold mining, avoiding a chronic impact of the metal on the health of people and the environment. (author)

Reflection of equatorial Kelvin waves at eastern ocean boundaries Part I: hypothetical boundaries

Directory of Open Access Journals (Sweden)

J. Soares

1999-06-01

Full Text Available A baroclinic shallow-water model is developed to investigate the effect of the orientation of the eastern ocean boundary on the behavior of equatorial Kelvin waves. The model is formulated in a spherical polar coordinate system and includes dissipation and non-linear terms, effects which have not been previously included in analytical approaches to the problem. Both equatorial and middle latitude response are considered given the large latitudinal extent used in the model. Baroclinic equatorial Kelvin waves of intraseasonal, seasonal and annual periods are introduced into the domain as pulses of finite width. Their subsequent reflection, transmission and dissipation are investigated. It is found that dissipation is very important for the transmission of wave energy along the boundary and for reflections from the boundary. The dissipation was found to be dependent not only on the presence of the coastal Kelvin waves in the domain, but also on the period of these coastal waves. In particular the dissipation increases with wave period. It is also shown that the equatorial β-plane approximation can allow an anomalous generation of Rossby waves at higher latitudes. Nonlinearities generally have a small effect on the solutions, within the confines of this model.Key words.

200 years ago - on September 24, 1789 - the pharmacist Martin Heinrich Klaproth (1743-1817) stated his discovery of uranium in the hearing of the Royal Prussian Academy of sciences in Berlin. This jubilee gave occasion to appreciate that discovery. The first part of the paper gives a brief bibliography of the researcher. His course of life from a pharmaceutical apprentice to the leading analytical chemist of his epoch is outlined; his performance and discoveries, in particular in the field of mineral chemistry, are appreciated. The second part deals with the discovery of uranium and his lifelong pursuit of the new metal in more detail. After briefly appreciating Klaproth's personality as a researcher, finally the importance is indicated that uranium meanwhile has gained as a source of nuclear power for the human race. (author).

Ob the Froissart-Martin bound in spaces with compact dimensions

CERN Document Server

Petrov, V A

2002-01-01

It is shown by the example of the 5-dimensional space-time, that by availability of the additional compact (space-time-like) measurements to the general Minkowski space all the conditions for proving the Froissart-Martin bound retain their force. Thus, by the circumference R -> 0 the theory smoothly transfers to the theory of the neutral scalar field in the 4-dimensional Minkowski space-time. It was assumed in this work, that the masses are bound from below by the non-zero value. The bounds for elastic scattering by absence of the mass gap are trivial, however in this case it is obviously possible to obtain also nontrivial bounds for complete inelastic cross sections. It takes place in the Regge-eikonal approach though there exist no strong proof for it

Naohiro eNakamura

2015-11-01

Full Text Available Although the energy transmitting boundary is accurate and efficient for the FEM earthquake response analysis, it could be applied in the frequency domain only. In the previous papers, the author proposed an earthquake response analysis method using the time domain energy transmitting boundary for two dimensional problems. In this paper, this technique is expanded for three dimensional problems. The inner field is supposed to be a hexahedron shape and the approximate time domain boundary is explained, first. Next, two dimensional anti-plane time domain boundary is studied for a part of the approximate three dimensional boundary method. Then, accuracy and efficiency of the proposed method are confirmed by example problems.

Mixed Boundary Value Problem on Hypersurfaces

R. DuDuchava

2014-01-01

Full Text Available The purpose of the present paper is to investigate the mixed Dirichlet-Neumann boundary value problems for the anisotropic Laplace-Beltrami equation divC(A∇Cφ=f on a smooth hypersurface C with the boundary Γ=∂C in Rn. A(x is an n×n bounded measurable positive definite matrix function. The boundary is decomposed into two nonintersecting connected parts Γ=ΓD∪ΓN and on ΓD the Dirichlet boundary conditions are prescribed, while on ΓN the Neumann conditions. The unique solvability of the mixed BVP is proved, based upon the Green formulae and Lax-Milgram Lemma. Further, the existence of the fundamental solution to divS(A∇S is proved, which is interpreted as the invertibility of this operator in the setting Hp,#s(S→Hp,#s-2(S, where Hp,#s(S is a subspace of the Bessel potential space and consists of functions with mean value zero.

Antireflective Boundary Conditions for Deblurring Problems

Directory of Open Access Journals (Sweden)

Marco Donatelli

2010-01-01

Full Text Available This survey paper deals with the use of antireflective boundary conditions for deblurring problems where the issues that we consider are the precision of the reconstruction when the noise is not present, the linear algebra related to these boundary conditions, the iterative and noniterative regularization solvers when the noise is considered, both from the viewpoint of the computational cost and from the viewpoint of the quality of the reconstruction. In the latter case, we consider a reblurring approach that replaces the transposition operation with correlation. For many of the considered items, the anti-reflective algebra coming from the given boundary conditions is the optimal choice. Numerical experiments corroborating the previous statement and a conclusion section end the paper.

Casimir pistons with general boundary conditions

Directory of Open Access Journals (Sweden)

Guglielmo Fucci

2015-02-01

Full Text Available In this work we analyze the Casimir energy and force for a scalar field endowed with general self-adjoint boundary conditions propagating in a higher dimensional piston configuration. The piston is constructed as a direct product I×N, with I=[0,L]⊂R and N a smooth, compact Riemannian manifold with or without boundary. The study of the Casimir energy and force for this configuration is performed by employing the spectral zeta function regularization technique. The obtained analytic results depend explicitly on the spectral zeta function associated with the manifold N and the parameters describing the general boundary conditions imposed. These results are then specialized to the case in which the manifold N is a d-dimensional sphere.

The Eighth Annual NASA/Contractors Conference and 1991 National Symposium on Quality and Productivity provided a forum to exchange knowledge and experiences in these areas of continuous improvement. The more than 1,100 attendees from government, industry, academia, community groups, and the international arena had a chance to learn about methods, tools, and strategies for excellence and to discuss continuous improvement strategies, successes, and failures. This event, linked via satellite to concurrent conferences hosted by the NASA Goddard Space Flight Center in Greenbelt, Maryland, and Martin Marietta Astronautics Group in Denver, Colorado, also explored extending the boundaries of Total Quality Management to include partnerships for quality within communities and encouraged examination, evaluation, and change to incorporate the principles of continuous improvement.

Conformal boundary loop models

Jacobsen, Jesper Lykke; Saleur, Hubert

2008-01-01

We study a model of densely packed self-avoiding loops on the annulus, related to the Temperley-Lieb algebra with an extra idempotent boundary generator. Four different weights are given to the loops, depending on their homotopy class and whether they touch the outer rim of the annulus. When the weight of a contractible bulk loop x≡q+q -1 element of (-2,2], this model is conformally invariant for any real weight of the remaining three parameters. We classify the conformal boundary conditions and give exact expressions for the corresponding boundary scaling dimensions. The amplitudes with which the sectors with any prescribed number and types of non-contractible loops appear in the full partition function Z are computed rigorously. Based on this, we write a number of identities involving Z which hold true for any finite size. When the weight of a contractible boundary loop y takes certain discrete values, y r ≡([r+1] q )/([r] q ) with r integer, other identities involving the standard characters K r,s of the Virasoro algebra are established. The connection with Dirichlet and Neumann boundary conditions in the O(n) model is discussed in detail, and new scaling dimensions are derived. When q is a root of unity and y=y r , exact connections with the A m type RSOS model are made. These involve precise relations between the spectra of the loop and RSOS model transfer matrices, valid in finite size. Finally, the results where y=y r are related to the theory of Temperley-Lieb cabling

POPULARIZING EPIC NARRATIVE IN GEORGE R.R. MARTIN'S A GAME OF THRONES

2012-11-01

Full Text Available This research is intended to show the sustainability of epic in latest years of human history through the most phenomenal fantasy in American literature, A Game of Thrones. Along with the capability of human beings in thinking dearly and sensibly, it is commonsensical that people tend to free themselves from irrationality. The reality shows, however, that the existence of epic fantasy still has power in appealing audiences or readers. This is the case with A Game of Thrones written by George RR Martin who was given the award of One of The Most Influential People in 2011 by Time magazine. This qualitative march, using genre approach, finds out that in order to be compatible with today's society, an epic seen in A Game of Thrones, which is commonly known as a story centering on the legendary hero and his heroic deed in oral folk tradition, keeps its power as an epic fantasy narrative through certain archetypes and formulas. Through genre analysis using semiotic approach, the research brings about conclusions that the elements of high fantasy, elements built through rational representation, and a smart combination of convention and invention brings about its popularity. It is also concluded that there is a close relationship between the myth and the mode of people living even in the most modern context.

The ratio between upstream and far downstream surface friction velocities relative to a change in surface roughness is given on the basis of results from surface Rossby number similarity theory. By simple theories for the internal boundary layer, which are found to compare quite well with recent...... numerical results from higher-order closure models, it is found that, even at a downwind distance such that the internal boundary layer has grown to the full height of the planetary boundary layers, the surface stress still considerably exceeds the equilibrium value...

Identifying Phase Space Boundaries with Voronoi Tessellations

2016-11-24

Determining the masses of new physics particles appearing in decay chains is an important and longstanding problem in high energy phenomenology. Recently it has been shown that these mass measurements can be improved by utilizing the boundary of the allowed region in the fully differentiable phase space in its full dimensionality. Here we show that the practical challenge of identifying this boundary can be solved using techniques based on the geometric properties of the cells resulting from Voronoi tessellations of the relevant data. The robust detection of such phase space boundaries in the data could also be used to corroborate a new physics discovery based on a cut-and-count analysis.

According to the facial feedback hypothesis, people's affective responses can be influenced by their own facial expression (e.g., smiling, pouting), even when their expression did not result from their emotional experiences. For example, Strack, Martin, and Stepper (1988) instructed participants to rate the funniness of cartoons using a pen that they held in their mouth. In line with the facial feedback hypothesis, when participants held the pen with their teeth (inducing a "smile"), they rated the cartoons as funnier than when they held the pen with their lips (inducing a "pout"). This seminal study of the facial feedback hypothesis has not been replicated directly. This Registered Replication Report describes the results of 17 independent direct replications of Study 1 from Strack et al. (1988), all of which followed the same vetted protocol. A meta-analysis of these studies examined the difference in funniness ratings between the "smile" and "pout" conditions. The original Strack et al. (1988) study reported a rating difference of 0.82 units on a 10-point Likert scale. Our meta-analysis revealed a rating difference of 0.03 units with a 95% confidence interval ranging from -0.11 to 0.16. © The Author(s) 2016.

Model-based estimation with boundary side information or boundary regularization

Chiao, P.C.; Rogers, W.L.; Fessler, J.A.; Clinthorne, N.H.; Hero, A.O.

1994-01-01

The authors have previously developed a model-based strategy for joint estimation of myocardial perfusion and boundaries using ECT (Emission Computed Tomography). The authors have also reported difficulties with boundary estimation in low contrast and low count rate situations. In this paper, the authors propose using boundary side information (obtainable from high resolution MRI and CT images) or boundary regularization to improve both perfusion and boundary estimation in these situations. To fuse boundary side information into the emission measurements, the authors formulate a joint log-likelihood function to include auxiliary boundary measurements as well as ECT projection measurements. In addition, the authors introduce registration parameters to align auxiliary boundary measurements with ECT measurements and jointly estimate these parameters with other parameters of interest from the composite measurements. In simulated PET O-15 water myocardial perfusion studies using a simplified model, the authors show that the joint estimation improves perfusion estimation performance and gives boundary alignment accuracy of <0.5 mm even at 0.2 million counts. The authors implement boundary regularization through formulating a penalized log-likelihood function. The authors also demonstrate in simulations that simultaneous regularization of the epicardial boundary and myocardial thickness gives comparable perfusion estimation accuracy with the use of boundary side information

Full Text Available Historical ethical dilemmas are a valuable tool in bioethics courses. However, garnering student interest in reading and discussing the assigned cases in the classroom can be challenging. In an effort to actively engage undergraduate and graduate students in an Ethical Issues in Biotechnology course, an activity was developed to encourage reflection on a classical ethical dilemma between a patient, St. Martin, and his employer/caretaker, Beaumont. Two different texts were used to analyze the ethical ramifications of this relationship: a chapter in a popular press book and a short perspective in a medical journal. Participants read the book chapter for homework and discussed it in class. This easy read highlights the fundamental ethical issues in the relationship between two men. Students were then provided with a second text focusing on the scientific accomplishments achieved through Beaumont's experimentation on St. Martin. A structured worksheet prompted participants to reflect on their feelings after reading each text and create a concept map depicting the dilemma. Student-generated concept maps and written reflections indicate participants were able to list the ethical issues, analyze the situation, and evaluate the information provided. This activity not only encouraged higher-level thinking and reflection, it also mirrored the course's structured approach of using concept mapping and reflection to dissect ethical dilemmas.

From boundaries to boundary work: middle managers creating inter-organizational change.

Oldenhof, Lieke; Stoopendaal, Annemiek; Putters, Kim

2016-11-21

Purpose In healthcare, organizational boundaries are often viewed as barriers to change. The purpose of this paper is to show how middle managers create inter-organizational change by doing boundary work: the dual act of redrawing boundaries and coordinating work in new ways. Design/methodology/approach Theoretically, the paper draws on the concept of boundary work from Science and Technology Studies. Empirically, the paper is based on an ethnographic investigation of middle managers that participate in a Dutch reform program across health, social care, and housing. Findings The findings show how middle managers create a sense of urgency for inter-organizational change by emphasizing "fragmented" service provision due to professional, sectoral, financial, and geographical boundaries. Rather than eradicating these boundaries, middle managers change the status quo gradually by redrawing composite boundaries. They use boundary objects and a boundary-transcending vocabulary emphasizing the need for societal gains that go beyond production targets of individual organizations. As a result, work is coordinated in new ways in neighborhood teams and professional expertise is being reconfigured. Research limitations/implications Since boundary workers create incremental change, it is necessary to follow their work for a longer period to assess whether boundary work contributes to paradigm change. Practical implications Organizations should pay attention to conditions for boundary work, such as legitimacy of boundary workers and the availability of boundary spaces that function as communities of practice. Originality/value By shifting the focus from boundaries to boundary work, this paper gives valuable insights into "how" boundaries are redrawn and embodied in objects and language.

The Conergy company, based in Hamburg, is active on five continents and is one of the world's most successful renewable energy businesses. Its turnover is about 800 million Euros and it has a staff of 1200. Hans-Martin Rueter founded the company in 1998 and is currently its Chief Executive Officer. In an interview, he revealed that he expects the renewables market will be worth US$300 billion by 2015. He sees three major market sectors to be exploited: they are (a) power-plant scale installations; (b) 'solitaire' installations such as homeowners might purchase and (c) network systems using a combination of systems such as PV with wind. Rueter is already expanding into new markets worldwide and becoming less dependent on the German market. He explains his strategy for finding new markets and providing what the customer wants.

Full Text Available Nesta comunicação procuramos mostrar a propriedade das idéias de Martin Buber, na obra Eu e Tu (2001, para se pensar as inter-relações na escola. Em termos antropológicos, no cotidiano escolar se configuram, simultaneamente, cultura organizacional e a cultura de grupos, segundo Edgar Morin (1984 e Michel Maffesoli (1998. Buscamos na “filosofia do encontro” uma reflexão sobre as relações inter-subjetivas produzidas pelos sujeitos no cotidiano escolar. São relações que efetivam a comunicação, definida por Buber como um encontro, no qual se dá a complementaridade e reciprocidade das ações entre o Eu-Tu, o dialógico, em detrimento à experiência de contato proporcionada no Eu-Isso, o monológico. A questão a ser iluminada diz respeito ao fato de que, por meio da “filosofia do encontro”, talvez possamos encontrar suportes teóricos consistentes para repensarmos as relações produzidas pelos sujeitos no âmbito escolar, o que evidencia o caráter “ontológico” de uma questão crucial na escola: ensino-aprendizagem. Abstract: This paper will attempt to point out relevance of the ideas of Martin Buber, in the work “I and Thou” (2001, to think the interrelations in school. In anthropological terms, in the school daily life both organizational culture and the culture of groups are established, according Edgar Morin (1984 and Michel Maffesoli (1998. We searched on the “Philosophy of the Meeting" a reflection on the inter-subjective relations produced by the subjects in the everyday life school. They are relations that implement the communication, defined by Buber as an encounter, which gave the complementarity and reciprocity of actions between the “I-Thou”, the dialogical, to the detriment of the experience of contact provided in the “I-That”, the monological. The issue to be enlightened relates to the fact that, through the "philosophy of the meeting," perhaps we can find consistent theoretical support in

Mercury (Hg) is a heavy metal, considered a highly toxic pollutant. In its elemental state is volatile, making it easy to transport over long distances through the atmosphere, so that environmental pollution caused by it is a serious problem worldwide. Activities such as gold mining, where metallic Hg is used, have contributed with its global distribution, affecting ecosystems and human health. The aim of this study was to determine the levels of total mercury (T-Hg) in air in gold mining areas in Southern Bolivar, particularly in the mining district of San Martin de Loba, in the municipalities of San Martin de Loba and Barranco de Loba (Mina Santa Cruz), Colombia. In situ analyses were performed by atomic absorption spectroscopy, using a portable Ra-915 + Zeeman mercury analyzer. In Mina Santa Cruz, one of the most important gold mines in Colombia, concentrations of Hg in air ranged between 163.7 ± 6.6 and 40 455 ± 2154 mg/m 3 , while in the urban area of San Martin de Loba varied from 223.6 ± 20.8 to 27 140 ± 212.5 ng/m 3 . In those places where an amalgam burning process was taking place at the time of the measurements, Hg concentrations reached values of 40 455 ± 2154 ng/m 3 . These data imply a severe occupational exposure to Hg for operators and citizens living in cities located near mines. Therefore, it is important to regulate and control the use of Hg in gold mining, avoiding a chronic impact of the metal on the health of people and the environment. (author)

Prosodic boundaries in writing: Evidence from a keystroke analysis

Directory of Open Access Journals (Sweden)

Susanne Fuchs

2016-11-01

Full Text Available The aim of the paper is to investigate duration between successive keystrokes during typing in order to examine whether prosodic boundaries are expressed in the process of writing. In particular, we are interested in interkey durations that occur next to punctuation marks (comma and full stops while taking keystrokes between words as a reference, since these punctuation marks are often realized with minor or major prosodic boundaries during reading. A two-part experiment was conducted: first, participants’ keystrokes on a computer keyboard were recorded while writing an email to a close friend (in two conditions: with and without time pressure. Second, participants read the email they just wrote. Interkey durations were compared to pause durations at the same locations during read speech. Results provide evidence of significant differences between interkey durations between words, at commas and at full stops (from shortest to longest. These durations were positively correlated with silent pause durations during reading. A more detailed analysis of interkey durations revealed patterns that can be interpreted with respect to prosodic boundaries in speech production, namely as phrase-final and phrase-initial lengthening occurring at punctuation marks. This work provides initial evidence that prosodic boundaries are reflected in the writing process.

Determining the masses of new physics particles appearing in decay chains is an important and longstanding problem in high energy phenomenology. Recently it has been shown that these mass measurements can be improved by utilizing the boundary of the allowed region in the fully differentiable phase space in its full dimensionality. Here we show that the practical challenge of identifying this boundary can be solved using techniques based on the geometric properties of the cells resulting from Voronoi tessellations of the relevant data. The robust detection of such phase-space boundaries in the data could also be used to corroborate a new physics discovery based on a cut-and-count analysis. (orig.)

In many physical scenarios, close relations between the bulk properties of quantum systems and theories associated to their boundaries have been observed. In this work, we provide an exact duality mapping between the bulk of a quantum spin system and its boundary using Projected Entangled Pair States (PEPS). This duality associates to every region a Hamiltonian on its boundary, in such a way that the entanglement spectrum of the bulk corresponds to the excitation spectrum of the boundary Hamiltonian. We study various models and find that a gapped bulk phase with local order corresponds to a boundary Hamiltonian with local interactions, whereas critical behavior in the bulk is reflected on a diverging interaction length of the boundary Hamiltonian. Furthermore, topologically ordered states yield non-local Hamiltonians. As our duality also associates a boundary operator to any operator in the bulk, it in fact provides a full holographic framework for the study of quantum many-body systems via their boundary.

Hartmann, E

1989-11-01

Previous work by the author and his collaborators on frequent nightmare sufferers demonstrated that these people had striking personality characteristics which could be called "thin boundaries" in a number of different senses. In order to measure thin and thick boundaries, a 145-item questionnaire, the Boundary Questionnaire, has been developed which has now been taken by over 1,000 persons. Preliminary results are presented indicating that, as predicted a priori, several new groups of nightmare sufferers and groups of art students scored usually "thin," whereas a group of naval officers had usually "thick" boundaries. Overall, thinness on the Boundary Questionnaire correlated highly positively (r = .40) with frequency of dream recall and also significantly (r = .16) with length of sleep.

In this article, we describe Martin Mayman's approach to early childhood memories as a projective technique, beginning with his scientific interest in learning theory, coupled with his interest in ego psychology and object relations theory. We describe Mayman's contributions to the use of the early memories technique to inform the psychotherapy process, tying assessment closely to psychotherapy and making assessment more useful in treatment. In this article, we describe a representative sample of research studies that demonstrate the reliability and validity of early memories, followed by case examples in which the early memories informed the therapy process, including issues of transference and countertransference.

A Novel Mesh Quality Improvement Method for Boundary Elements

Directory of Open Access Journals (Sweden)

Hou-lin Liu

2012-01-01

Full Text Available In order to improve the boundary mesh quality while maintaining the essential characteristics of discrete surfaces, a new approach combining optimization-based smoothing and topology optimization is developed. The smoothing objective function is modified, in which two functions denoting boundary and interior quality, respectively, and a weight coefficient controlling boundary quality are taken into account. In addition, the existing smoothing algorithm can improve the mesh quality only by repositioning vertices of the interior mesh. Without destroying boundary conformity, bad elements with all their vertices on the boundary cannot be eliminated. Then, topology optimization is employed, and those elements are converted into other types of elements whose quality can be improved by smoothing. The practical application shows that the worst elements can be eliminated and, with the increase of weight coefficient, the average quality of boundary mesh can also be improved. Results obtained with the combined approach are compared with some common approach. It is clearly shown that it performs better than the existing approach.

The Concept of Origin in Meister Eckhart and the Philosophical Relevance of his Thought in the Work of Martin Heidegger

Directory of Open Access Journals (Sweden)

Ricardo Baeza García

2013-11-01

Full Text Available The intention of this article is twofold. In one hand it exposes the issue concerning the response to the question about the origin in Meister Eckhart’s work. In order to answer this question, the article at hand analyzes the concepts of eigenschaft and gêlazenheit, which are fundamental within the Eckhartian thought. The purpose of this first block is to demonstrate to what extent the work of this author stems from the coordinates of the scholastic-medieval discourse, unfolding a thought of great originality and philosophical interest. On the other hand, the present article analyzes, in the third section, the influence of the Eckhartian mysticism in the work of Martin Heidegger. The fundamental aim of this second thematic block is to reveal in what way the work of Eckhart transcends the parameters of what Heidegger understands as metaphysical thought

For scalar and electromagnetic fields we evaluate the vacuum expectation value of the energy-momentum tensor induced by a curved boundary in the Robertson-Walker spacetime with negative spatial curvature. In order to generate the vacuum densities we use the conformal relation between the Robertson-Walker and Rindler spacetimes and the corresponding results for a plate moving by uniform proper acceleration through the Fulling-Rindler vacuum. For the general case of the scale factor the vacuum energy-momentum tensor is presented as the sum of the boundary free and boundary induced parts.

Characterization of floodflows along the Arkansas River without regulation by Pueblo Reservoir, Portland to John Martin Reservoir, Southeastern Colorado

Science.gov (United States)

Little, John R.; Bauer, Daniel P.

1981-01-01

The need for a method for estimating flow characteristics of flood hydrographs between Portland, Colo., and John Martin Reservoir has been promoted with the construction of the Pueble Reservoir. To meet this need a procedure was developed for predicting floodflow peaks, traveltimes, and volumes at any point along the Arkansas River between Portland and John Martin Reservoir without considering the existing Pueble Reservoir detention effects. A streamflow-routing model was calibrated initially and then typical flood simulations were made for the 164.8-mile study reach. Simulations were completed for varying magnitudes of floods and antecedent streamflow conditions. Multiple regression techniques were then used with simulation results as input to provide predictive relationships for food peak, volume, and traveltime. Management practices that may be used to benefit water users in the area include providing methods for the distribution and allotment of the flood waters upstream of Portland to different downstream water users according to Colorado water law and also under the Arkansas River Compact.

Khambampati, Anil Kumar; Kim, Sin; Lee, Bo An; Kim, Kyung Youn

2012-01-01

This paper is about locating the boundary of a moving cavity within a homogeneous background from the voltage measurements recorded on the outer boundary. An inverse boundary problem of a moving cavity is formulated by considering a two-phase vapor–liquid flow in a pipe. The conductivity of the flow components (vapor and liquid) is assumed to be constant and known a priori while the location and shape of the inclusion (vapor) are the unknowns to be estimated. The forward problem is solved using the boundary element method (BEM) with the integral equations solved analytically. A special situation is considered such that the cavity changes its location and shape during the time taken to acquire a full set of independent measurement data. The boundary of a cavity is assumed to be elliptic and is parameterized with Fourier series. The inverse problem is treated as a state estimation problem with the Fourier coefficients that represent the center and radii of the cavity as the unknowns to be estimated. An extended Kalman filter (EKF) is used as an inverse algorithm to estimate the time varying Fourier coefficients. Numerical experiments are shown to evaluate the performance of the proposed method. Through the results, it can be noticed that the proposed BEM with EKF method is successful in estimating the boundary of a moving cavity. (paper)

Regularization of the Boundary-Saddle-Node Bifurcation

Directory of Open Access Journals (Sweden)

Xia Liu

2018-01-01

Full Text Available In this paper we treat a particular class of planar Filippov systems which consist of two smooth systems that are separated by a discontinuity boundary. In such systems one vector field undergoes a saddle-node bifurcation while the other vector field is transversal to the boundary. The boundary-saddle-node (BSN bifurcation occurs at a critical value when the saddle-node point is located on the discontinuity boundary. We derive a local topological normal form for the BSN bifurcation and study its local dynamics by applying the classical Filippov’s convex method and a novel regularization approach. In fact, by the regularization approach a given Filippov system is approximated by a piecewise-smooth continuous system. Moreover, the regularization process produces a singular perturbation problem where the original discontinuous set becomes a center manifold. Thus, the regularization enables us to make use of the established theories for continuous systems and slow-fast systems to study the local behavior around the BSN bifurcation.

To address a critical gap in the social work literature, this article examines the deleterious effects of racial profiling as it pertains to police targeting of male African Americans. The authors use the Trayvon Martin court case to exemplify how racial profiling and black male stigma help perpetuate social inequality and injustice for black men. A racism-centered perspective is examined historically and contemporarily as a theoretical approach to understanding the role that race plays in social injustice through racial profiling. Implications for social work research design and practice aimed at increasing the social work knowledge base on racial profiling are discussed. The authors call for attention and advocacy by major social work organizations in the reduction of black male stigma and racial profiling. © 2017 National Association of Social Workers.

The discovery of uranium by Martin Heinrich Klaproth 200 years ago

Schuettmann, W.

1989-01-01

200 years ago - on September 24, 1789 - the pharmacist Martin Heinrich Klaproth (1743-1817) stated his discovery of uranium in the hearing of the Royal Prussian Academy of sciences in Berlin. This jubilee gave occasion to appreciate that discovery. The first part of the paper gives a brief bibliography of the researcher. His course of life from a pharmaceutical apprentice to the leading analytical chemist of his epoch is outlined; his performance and discoveries, in particular in the field of mineral chemistry, are appreciated. The second part deals with the discovery of uranium and his lifelong pursuit of the new metal in more detail. After briefly appreciating Klaproth's personality as a researcher, finally the importance is indicated that uranium meanwhile has gained as a source of nuclear power for the human race. (author)

Defensible Spaces in Philadelphia: Exploring Neighborhood Boundaries Through Spatial Analysis

Directory of Open Access Journals (Sweden)

Rory Kramer

2017-02-01

Full Text Available Few spatial scales are as important to individual outcomes as the neighborhood. However, it is nearly impossible to define neighborhoods in a generalizable way. This article proposes that by shifting the focus to measuring neighborhood boundaries rather than neighborhoods, scholars can avoid the problem of the indefinable neighborhood and better approach questions of what predicts racial segregation across areas. By quantifying an externality space theory of neighborhood boundaries, this article introduces a novel form of spatial analysis to test where potential physical markers of neighborhood boundaries (major roads, rivers, railroads, and the like are associated with persistent racial boundaries between 1990 and 2010. Using Philadelphia as a case study, the paper identifies neighborhoods with persistent racial boundaries. It theorizes that local histories of white reactions to black in-migration explain which boundaries persistently resisted racial turnover, unlike the majority of Philadelphia’s neighborhoods, and that those racial boundaries shape the location, progress, and reaction to new residential development in those neighborhoods.

Elvin, John D.

1996-03-01

This paper discusses Lockheed Martin's perspective on the development of a cost effective Reusable Launch Vehicle (RLV). Critical to a successful Single Stage To Orbit (SSTO) program are; an economic development plan sensitive to fiscal constraints; a vehicle concept satisfying present and future US launch needs; and an operations concept commensurate with a market driven program. Participation in the economic plan by government, industry, and the commercial sector is a key element of integrating our development plan and funding profile. The RLV baseline concept design, development evolution and several critical trade studies illustrate the superior performance achieved by our innovative approach to the problem of SSTO. Findings from initial aerodynamic and aerothermodynamic wind tunnel tests and trajectory analyses on this concept confirm the superior characteristics of the lifting body shape combined with the Linear Aerospike rocket engine. This Aero Ballistic Rocket (ABR) concept captures the essence of The Skunk Works approach to SSTO RLV technology integration and system engineering. These programmatic and concept development topics chronicle the key elements to implementing an innovative market driven next generation RLV.

The Martin Marietta Energy Systems personnel neutron dosimetry program

McMahan, K.L.

1991-01-01

Martin Marietta Energy Systems, Inc. (Energy Systems), manages five sites for the US Department of Energy. Personnel dosimetry for four of the five sites is coordinated through a Centralized External Dosimetry System (CEDS). These four sites are the Oak Ridge National Laboratory (ORNL), the Oak Ridge Y-12 Plant (Y-12), the Oak Ridge K-25 Site (K-25), and the Paducah Gaseous Diffusion Plant (PGDP). The fifth Energy Systems site, Portsmouth Gaseous Diffusion Plant, has an independent personnel dosimetry program. The current CEDS personnel neutron dosimeter was first issued in January 1989, after an evaluation and characterization of the dosimeters' response in the workplaces was performed. For the workplace characterization, Energy Systems contracted with Pacific Northwest Laboratory (PNL) to perform neutron measurements at selected locations at ORNL and Y-12. K-25 and PGDP were not included because their neutron radiation fields were similar to others already planned for characterization at ORNL and Y-12. Since the initial characterization, PNL has returned to Oak Ridge twice to perform follow up measurements, and another visit is planned in the near future

The complex variable boundary element method: Applications in determining approximative boundaries

Hromadka, T.V.

1984-01-01

The complex variable boundary element method (CVBEM) is used to determine approximation functions for boundary value problems of the Laplace equation such as occurs in potential theory. By determining an approximative boundary upon which the CVBEM approximator matches the desired constant (level curves) boundary conditions, the CVBEM is found to provide the exact solution throughout the interior of the transformed problem domain. Thus, the acceptability of the CVBEM approximation is determined by the closeness-of-fit of the approximative boundary to the study problem boundary. ?? 1984.

Altered Ecological Flows Blur Boundaries in Urbanizing Watersheds

Directory of Open Access Journals (Sweden)

Todd R. Lookingbill

2009-12-01

Full Text Available The relevance of the boundary concept to ecological processes has been recently questioned. Humans in the post-industrial era have created novel lateral transport fluxes that have not been sufficiently considered in watershed studies. We describe patterns of land-use change within the Potomac River basin and demonstrate how these changes have blurred traditional ecosystem boundaries by increasing the movement of people, materials, and energy into and within the basin. We argue that this expansion of ecological commerce requires new science, monitoring, and management strategies focused on large rivers and suggest that traditional geopolitical and economic boundaries for environmental decision making be appropriately revised. Effective mitigation of the consequences of blurred boundaries will benefit from a broad-scale, interdisciplinary framework that can track and explicitly account for ecological fluxes of water, energy, materials, and organisms across human-dominated landscapes.

Mustafa Turkyilmazoglu

2016-02-01

Full Text Available A combined analytic-numeric approach is undertaken in the present work for the solution of boundary-value problems in the finite or semi-infinite domains. Equations to be treated arise specifically from the boundary layer analysis of some two and three-dimensional flows in fluid mechanics. The purpose is to find quick but accurate enough solutions. Taylor expansions at either boundary conditions are computed which are next matched to the other asymptotic or exact boundary conditions. The technique is applied to the well-known Blasius as well as Karman flows. Solutions obtained in terms of series compare favorably with the existing ones in the literature.

Boundary-bulk relation in topological orders

Directory of Open Access Journals (Sweden)

Liang Kong

2017-09-01

Full Text Available In this paper, we study the relation between an anomaly-free n+1D topological order, which are often called n+1D topological order in physics literature, and its nD gapped boundary phases. We argue that the n+1D bulk anomaly-free topological order for a given nD gapped boundary phase is unique. This uniqueness defines the notion of the “bulk” for a given gapped boundary phase. In this paper, we show that the n+1D “bulk” phase is given by the “center” of the nD boundary phase. In other words, the geometric notion of the “bulk” corresponds precisely to the algebraic notion of the “center”. We achieve this by first introducing the notion of a morphism between two (potentially anomalous topological orders of the same dimension, then proving that the notion of the “bulk” satisfies the same universal property as that of the “center” of an algebra in mathematics, i.e. “bulk = center”. The entire argument does not require us to know the precise mathematical description of a (potentially anomalous topological order. This result leads to concrete physical predictions.

Here, we investigate full-wave simulations of realistic implementations of multifunctional nanoantenna enabled detectors (NEDs). We focus on a 2x2 pixelated array structure that supports two wavelengths of operation. We design each resonating structure independently using full-wave simulations with periodic boundary conditions mimicking the whole infinite array. We then construct a supercell made of a 2x2 pixelated array with periodic boundary conditions mimicking the full NED; in this case, however, each pixel comprises 10-20 antennas per side. In this way, the cross-talk between contiguous pixels is accounted for in our simulations. We observe that, even though there are finite extent effects, the pixels work as designed, each responding at the respective wavelength of operation. This allows us to stress that realistic simulations of multifunctional NEDs need to be performed to verify the design functionality by taking into account finite extent and cross-talk effects.

Boundary effects and gapped dispersion in rotating fermionic matter

Directory of Open Access Journals (Sweden)

Shu Ebihara

2017-01-01

Full Text Available We discuss the importance of boundary effects on fermionic matter in a rotating frame. By explicit calculations at zero temperature we show that the scalar condensate of fermion and anti-fermion cannot be modified by the rotation once the boundary condition is properly implemented. The situation is qualitatively changed at finite temperature and/or in the presence of a sufficiently strong magnetic field that supersedes the boundary effects. Therefore, to establish an interpretation of the rotation as an effective chemical potential, it is crucial to consider further environmental effects such as the finite temperature and magnetic field.

Boundary element method for internal axisymmetric flow

Directory of Open Access Journals (Sweden)

Gokhman Alexander

1999-01-01

Full Text Available We present an accurate fast method for the computation of potential internal axisymmetric flow based on the boundary element technique. We prove that the computed velocity field asymptotically satisfies reasonable boundary conditions at infinity for various types of inlet/exit. Computation of internal axisymmetric potential flow is an essential ingredient in the three-dimensional problem of computation of velocity fields in turbomachines. We include the results of a practical application of the method to the computation of flow in turbomachines of Kaplan and Francis types.

Relaxation processes of kinetic nonequilibrium collisionless boundary layers near spherical charged full absorbing surfaces in binary low-temperature plasmas are investigated. The effect of magnetic field on relaxation processes was neglected. The dynamics of components of the ionized gas was treated near the boundary layer. The potential distribution and the space dependence of concentration were calculated numerically. These results agree well with the experimental data. (D.Gy.)

Lyapunov Based Estimation of Flight Stability Boundary under Icing Conditions

Directory of Open Access Journals (Sweden)

Binbin Pei

2017-01-01

Full Text Available Current fight boundary of the envelope protection in icing conditions is usually defined by the critical values of state parameters; however, such method does not take the interrelationship of each parameter and the effect of the external disturbance into consideration. This paper proposes constructing the stability boundary of the aircraft in icing conditions through analyzing the region of attraction (ROA around the equilibrium point. Nonlinear icing effect model is proposed according to existing wind tunnel test results. On this basis, the iced polynomial short period model can be deduced further to obtain the stability boundary under icing conditions using ROA analysis. Simulation results for a series of icing severity demonstrate that, regardless of the icing severity, the boundary of the calculated ROA can be treated as an estimation of the stability boundary around an equilibrium point. The proposed methodology is believed to be a promising way for ROA analysis and stability boundary construction of the aircraft in icing conditions, and it will provide theoretical support for multiple boundary protection of icing tolerant flight.

Slow Manifolds and Multiple Equilibria in Stratocumulus-Capped Boundary Layers

Directory of Open Access Journals (Sweden)

Junya Uchida

2010-12-01

Full Text Available In marine stratocumulus-capped boundary layers under strong inversions, the timescale for thermodynamic adjustment is roughly a day, much shorter than the multiday timescale for inversion height adjustment. Slow-manifold analysis is introduced to exploit this timescale separation when boundary layer air columns experience only slow changes in their boundary conditions. Its essence is that the thermodynamic structure of the boundary layer remains approximately slaved to its inversion height and the instantaneous boundary conditions; this slaved structure determines the entrainment rate and hence the slow evolution of the inversion height. Slow-manifold analysis is shown to apply to mixed-layer model and large-eddy simulations of an idealized nocturnal stratocumulus- capped boundary layer; simulations with different initial inversion heights collapse onto single relationships of cloud properties with inversion height. Depending on the initial inversion height, the simulations evolve toward a shallow thin-cloud boundary layer or a deep, well-mixed thick cloud boundary layer. In the large-eddy simulations, these evolutions occur on two separate slow manifolds (one of which becomes unstable if cloud droplet concentration is reduced. Applications to analysis of stratocumulus observations and to pockets of open cells and ship tracks are proposed.

Full Text Available In order to solve the boundary value problem of fractional impulsive differential equations with countable impulses and integral boundary conditions on the half line, the existence of solutions to the boundary problem is specifically studied. By defining suitable Banach spaces, norms and operators, using the properties of fractional calculus and applying the contraction mapping principle and Krasnoselskii's fixed point theorem, the existence of solutions for the boundary value problem of fractional impulsive differential equations with countable impulses and integral boundary conditions on the half line is proved, and examples are given to illustrate the existence of solutions to this kind of equation boundary value problems.

Full Text Available Extraction of road boundary accurately from crowdsourcing trajectory lines is still a hard work.Therefore,this study presented a new approach to use vehicle trajectory lines to extract road boundary.Firstly, constructing constrained Delaunay triangulation within interpolated track lines to calculate road boundary descriptors using triangle edge length and Voronoi cell.Road boundary recognition model was established by integrating the two boundary descriptors.Then,based on seed polygons,a regional growing method was proposed to extract road boundary. Finally, taxi GPS traces in Beijing were used to verify the validity of the novel method, and the results also showed that our method was suitable for GPS traces with disparity density,complex road structure and different time interval.

2013-12-01

Full Text Available A two-dimensional incompressible laminar boundary layer and its control using blowing and suction over a flat plate and around the NACA 0012 and 661012 profiles, is studied numerically. The study is based on the Prandtl boundary layer model using the finite differences method and the Crank-Nicolson scheme. The velocity distribution, the boundary layer thickness and the friction coefficient, are determined and presented with and without control. The application of the control technique, has demonstrated its positive effect on the transition point and the friction coefficient. Both control procedures are compared for different lengths, speeds and angles of blowing and suction.

On a variational principle for shape optimization and elliptic free boundary problems

Raúl B. González De Paz

2009-02-01

Full Text Available A variational principle for several free boundary value problems using a relaxation approach is presented. The relaxed Energy functional is concave and it is defined on a convex set, so that the minimizing points are characteristic functions of sets. As a consequence of the first order optimality conditions, it is shown that the corresponding sets are domains bounded by free boundaries, so that the equivalence of the solution of the relaxed problem with the solution of several free boundary value problem is proved. Keywords: Calculus of variations, optimization, free boundary problems.

A Probabilistic Approach for Breast Boundary Extraction in Mammograms

Directory of Open Access Journals (Sweden)

Hamed Habibi Aghdam

2013-01-01

Full Text Available The extraction of the breast boundary is crucial to perform further analysis of mammogram. Methods to extract the breast boundary can be classified into two categories: methods based on image processing techniques and those based on models. The former use image transformation techniques such as thresholding, morphological operations, and region growing. In the second category, the boundary is extracted using more advanced techniques, such as the active contour model. The problem with thresholding methods is that it is a hard to automatically find the optimal threshold value by using histogram information. On the other hand, active contour models require defining a starting point close to the actual boundary to be able to successfully extract the boundary. In this paper, we propose a probabilistic approach to address the aforementioned problems. In our approach we use local binary patterns to describe the texture around each pixel. In addition, the smoothness of the boundary is handled by using a new probability model. Experimental results show that the proposed method reaches 38% and 50% improvement with respect to the results obtained by the active contour model and threshold-based methods respectively, and it increases the stability of the boundary extraction process up to 86%.

Model-based estimation with boundary side information or boundary regularization [cardiac emission CT].

Science.gov (United States)

Chiao, P C; Rogers, W L; Fessler, J A; Clinthorne, N H; Hero, A O

1994-01-01

The authors have previously developed a model-based strategy for joint estimation of myocardial perfusion and boundaries using ECT (emission computed tomography). They have also reported difficulties with boundary estimation in low contrast and low count rate situations. Here they propose using boundary side information (obtainable from high resolution MRI and CT images) or boundary regularization to improve both perfusion and boundary estimation in these situations. To fuse boundary side information into the emission measurements, the authors formulate a joint log-likelihood function to include auxiliary boundary measurements as well as ECT projection measurements. In addition, they introduce registration parameters to align auxiliary boundary measurements with ECT measurements and jointly estimate these parameters with other parameters of interest from the composite measurements. In simulated PET O-15 water myocardial perfusion studies using a simplified model, the authors show that the joint estimation improves perfusion estimation performance and gives boundary alignment accuracy of <0.5 mm even at 0.2 million counts. They implement boundary regularization through formulating a penalized log-likelihood function. They also demonstrate in simulations that simultaneous regularization of the epicardial boundary and myocardial thickness gives comparable perfusion estimation accuracy with the use of boundary side information.

Prosodic Boundaries in Writing: Evidence from a Keystroke Analysis.

Science.gov (United States)

Fuchs, Susanne; Krivokapić, Jelena

2016-01-01

The aim of the paper is to investigate duration between successive keystrokes during typing in order to examine whether prosodic boundaries are expressed in the process of writing. In particular, we are interested in interkey durations that occur next to punctuation marks (comma and full stops while taking keystrokes between words as a reference), since these punctuation marks are often realized with minor or major prosodic boundaries during overt reading. A two-part experiment was conducted: first, participants' keystrokes on a computer keyboard were recorded while writing an email to a close friend (in two conditions: with and without time pressure). Second, participants read the email they just wrote. Interkey durations were compared to pause durations at the same locations during read speech. Results provide evidence of significant differences between interkey durations between words, at commas and at full stops (from shortest to longest). These durations were positively correlated with silent pause durations during overt reading. A more detailed analysis of interkey durations revealed patterns that can be interpreted with respect to prosodic boundaries in speech production, namely as phrase-final and phrase-initial lengthening occurring at punctuation marks. This work provides initial evidence that prosodic boundaries are reflected in the writing process.

St. Vicent Ferrer’s Catalán sermon on St. Martin of Tours

Ferreiro, Alberto

2013-12-01

Full Text Available One of the most widely venerated saints in the Middle Ages was St. Martin of Tours whose cult continues to this day in many parts of the world. In the Middle Ages, he became as popular as other major saints such as Thomas Becket, Santiago de Compostela and the Virgin Mary. St. Martin’s cult became very prominent in the Iberian Peninsula before and after the emergence of the cult of Santiago de Compostela. In St. Vicent Ferrer’s voluminous sermons this one in Catalán is dedicated to this most venerated Gallic saint. The most important late antique and early medieval sources that form the background of this sermon are by Sulpicius Severus- the Gallus and Vita Sancti Martini. In the high Middle Ages, however, his cult was popularized through the Legenda Aurea written by the Dominican Jacobus of Voragine, who synthesized Sulpicius’ two works on St. Martin. Moreover, St. Vicent preached not to make any major doctrinal breakthroughs- his main interest was to evangelize, not to write academic theology- he nevertheless exhibited great creativity. The object of this study is St. Vicent’s Catalán sermon Alius Sermo Sancti Martini, CXXXIV.Uno de los santos más venerados en la edad media fue San Martín de Tours, cuyo culto continúa hasta hoy en muchas partes del mundo. En la edad media, se hizo tan popular como otros grandes Santos: Thomas Becket, Santiago de Compostela y la Virgen María.

En los sermones voluminosos de San Vicente Ferrer esta uno en Catalán que está dedicado a este santo tan venerado de Galia. Las fuentes más importantes procedentes de la antigu.edad tardía y principios medievales que forma el fondo de este sermón son Gallus y la Vita Sancti Martini de Sulpicio Severo. Sin embargo, en la alta edad media, su culto se popularizó a través de la Legenda Aurea escrita por el dominico

Radykalna interpretacja intencjonalności w filozofii Martina Heideggera (Radical interpretation of intentionality in Martin Heidegger’s philosophy

Directory of Open Access Journals (Sweden)

Andrzej Dąbrowski

2012-06-01

Full Text Available The aim of this paper is to present Martin Heidegger’s view on intentionality. We start from initial observations on the phenomenon of intentionality (here we refer to four possible concepts of intentionality: mentalistic, linguistic, pragmatic, and naturalistic and a few remarks on the fundamental ontology of Heidegger. Then we show what intentionality is not for Heidegger: fi rst, it is not an objectively existing relationship between two entities and, secondly, intentionality is not the subjectivity of the subject; and we specify what intentionality is: in Heidegger’s ontology, intentionality is closely related to the transcendence of being-in-the-world. Transcending – the constancy in crossing – Dasein enables it to refer to itself, other conscious beings, and, in general, all present entities. We have shown that none of the above concepts of intentionality (mentalistic, linguistic, pragmatic, and naturalistic is not congruent with the interpretation of Heidegger, which concentrates on the following issue: how to go beyond the traditional understanding of intentionality and reach a more basic form of experience.

Entropy Stability and the No-Slip Wall Boundary Condition

We present an entropy stable numerical scheme subject to no-slip wall boundary conditions. To enforce entropy stability only the no-penetration boundary condition and a temperature condition are needed at a wall, and this leads to an L bound on the conservative variables. In this article, we take the next step and design a finite difference scheme that also bounds the velocity gradients. This necessitates the use of the full no-slip conditions.

Effects of shock on hypersonic boundary layer stability

Science.gov (United States)

Pinna, F.; Rambaud, P.

2013-06-01

The design of hypersonic vehicles requires the estimate of the laminar to turbulent transition location for an accurate sizing of the thermal protection system. Linear stability theory is a fast scientific way to study the problem. Recent improvements in computational capabilities allow computing the flow around a full vehicle instead of using only simplified boundary layer equations. In this paper, the effect of the shock is studied on a mean flow provided by steady Computational Fluid Dynamics (CFD) computations and simplified boundary layer calculations.

Controllability for a Wave Equation with Moving Boundary

Directory of Open Access Journals (Sweden)

Lizhi Cui

2014-01-01

Full Text Available We investigate the controllability for a one-dimensional wave equation in domains with moving boundary. This model characterizes small vibrations of a stretched elastic string when one of the two endpoints varies. When the speed of the moving endpoint is less than 1-1/e, by Hilbert uniqueness method, sidewise energy estimates method, and multiplier method, we get partial Dirichlet boundary controllability. Moreover, we will give a sharper estimate on controllability time that only depends on the speed of the moving endpoint.

Method of interior boundaries in a mixed problem of acoustic scattering

Directory of Open Access Journals (Sweden)

P. A. Krutitskii

1999-01-01

Full Text Available The mixed problem for the Helmholtz equation in the exterior of several bodies (obstacles is studied in 2 and 3 dimensions. The Dirichlet boundary condition is given on some obstacles and the impedance boundary condition is specified on the rest. The problem is investigated by a special modification of the boundary integral equation method. This modification can be called ‘Method of interior boundaries’, because additional boundaries are introduced inside scattering bodies, where impedance boundary condition is given. The solution of the problem is obtained in the form of potentials on the whole boundary. The density in the potentials satisfies the uniquely solvable Fredholm equation of the second kind and can be computed by standard codes. In fact our method holds for any positive wave numbers. The Neumann, Dirichlet, impedance problems and mixed Dirichlet–Neumann problem are particular cases of our problem.

Reduction of Islands in Full-pressure Stellarator Equilibria

International Nuclear Information System (INIS)

Hudson, S.R.; Monticello, D.A.; Reiman, A.H.

2001-01-01

The control of magnetic islands is a crucial issue in designing Stellarators. Islands are associated with resonant radial magnetic fields at rational rotational-transform surfaces and can lead to chaos and poor plasma confinement. In this article, we show that variations in the resonant fields of a full-pressure stellarator equilibrium can be related to variations in the boundary via a coupling matrix, and inversion of this matrix determines a boundary modification for which the island content is significantly reduced. The numerical procedure is described and the results of island optimization are presented. Equilibria with islands are computed using the Princeton Iterative Equilibrium Solver, and resonant radial fields are calculated via construction of quadratic-flux-minimizing surfaces. A design candidate for the National Compact Stellarator Experiment [Phys. Plasmas 8, 2001], which has a large island, is used to illustrate the technique. Small variations in the boundary shape are used to reduce island size and to reverse the phase of a major island chain

Hydrogeological investigations conducted by the Geological Survey of Canada in the Lake Saint-Martin region of Manitoba have confirmed earlier reports of naturally elevated F - and B concentrations in local groundwaters. Fluoride and B concentrations are highly correlated (r 2 = 0.905) and reach 15.1 mg/L and 8.5 mg/L, respectively. Virtually all groundwaters with F - concentrations greater than the drinking water limit of 1.5 mg/L are from wells within the Lake Saint-Martin impact structure, a 208 Ma complex crater 23 km in diameter underlying a large part of the study area. The high-F - groundwaters can be classified into two groups according to their anionic and isotopic compositions. Group I samples consist of Na-mixed anion groundwaters, with Cl greater than 100 mg/L and highly depleted 18 O compositions indicative of recharge under much cooler climatic conditions than at present. Samples belonging to this group exhibit a striking relationship to crater morphology, and are found in an arcuate belt within the southern rim of the impact structure. Group II high-F - samples consist of Na-HCO 3 -SO 4 groundwaters, with little Cl, and less depleted 18 O compositions. Samples belonging to this group are associated with groundwaters recharged locally, on a low ridge within the impact structure. This paper traces the probable source of high-F - groundwaters to phosphatic pellets in shales of the Winnipeg Formation, a regional basal clastic unit which sub-crops at shallow depth beneath the crater rim as a result of more than 200 m of structural uplift associated with the impact event. This extensive aquifer is known elsewhere in southern Manitoba for its naturally-softened groundwaters and locally elevated F - concentrations. Group I groundwaters are interpreted as discharge from the Winnipeg Formation where it abuts against crater-fill deposits. Group II high-F - groundwaters are interpreted as modern recharge from within the impact structure, displacing Group I

Definition of Turbulent Boundary-Layer with Entropy Concept

Zhao Rui

2016-01-01

Full Text Available The relationship between the entropy increment and the viscosity dissipation in turbulent boundary-layer is systematically investigated. Through theoretical analysis and direct numerical simulation (DNS, an entropy function fs is proposed to distinguish the turbulent boundary-layer from the external flow. This approach is proved to be reliable after comparing its performance in the following complex flows, namely, low-speed airfoil flows with different wall temperature, supersonic cavity-ramp flow dominated by the combination of free-shear layer, larger recirculation and shocks, and the hypersonic flow past an aeroplane configuration. Moreover, fs is deduced from the point of energy, independent of any particular turbulent quantities. That is, this entropy concept could be utilized by other engineering applications related with turbulent boundary-layer, such as turbulence modelling transition prediction and engineering thermal protection.

Boundary effect on liquid invasion in tight gas reservoirs

Directory of Open Access Journals (Sweden)

Li Gao

2015-01-01

Full Text Available Liquid invasion is an important transport phenomenon in many geophysical and environmental applications. A new capillary model considering boundary effect is proposed to reveal its mechanism. The boundary fluid layer not only reduces the effective flow radius, but also changes the viscosity of fluid. Thus the capillary force and viscosity resistance increases, however, the increase of capillary force is faster than that of viscosity resistance, therefore the invasion front arrives at the critical distance earlier.

This work is a simulation technology demonstrator, of sweep jet flow control used to suppress boundary layer separation and increase the maximum achievable load coefficients. A sweep jet is a discrete Coanda jet that oscillates in the plane parallel to an aerodynamic surface. It injects mass and momentum in the approximate streamwise direction. It also generates turbulent eddies at the oscillation frequency, which are typically large relative to the scales of boundary layer turbulence, and which augment mixing across the boundary layer to attack flow separation. Simulations of a fluidic oscillator, the sweep jet emerging from a nozzle downstream of the oscillator, and an array of sweep jets which suppresses boundary layer separation are performed. Simulation results are compared to data from a dedicated validation experiment of a single oscillator and its sweep jet, and from a wind tunnel test of a full-scale Boeing 757 vertical tail augmented with an array of sweep jets. A critical step in the work is the development of realistic time-dependent sweep jet inflow boundary conditions, derived from the results of the single-oscillator simulations, which create the sweep jets in the full-tail simulations. Simulations were performed using the computational fluid dynamics (CFD) solver Overow, with high-order spatial discretization and a range of turbulence modeling. Good results were obtained for all flows simulated, when suitable turbulence modeling was used.

Fiat or bona fide boundary--a matter of granular perspective.

Directory of Open Access Journals (Sweden)

Lars Vogt

Full Text Available Distinguishing bona fide (i.e. natural and fiat (i.e. artificial physical boundaries plays a key role for distinguishing natural from artificial material entities and is thus relevant to any scientific formal foundational top-level ontology, as for instance the Basic Formal Ontology (BFO. In BFO, the distinction is essential for demarcating two foundational categories of material entity: object and fiat object part. The commonly used basis for demarcating bona fide from fiat boundary refers to two criteria: (i intrinsic qualities of the boundary bearers (i.e. spatial/physical discontinuity, qualitative heterogeneity and (ii mind-independent existence of the boundary. The resulting distinction of bona fide and fiat boundaries is considered to be categorial and exhaustive.By Referring to various examples from biology, we demonstrate that the hitherto used distinction of boundaries is not categorial: (i spatial/physical discontinuity is a matter of scale and the differentiation of bona fide and fiat boundaries is thus granularity-dependent, and (ii this differentiation is not absolute, but comes in degrees. By reducing the demarcation criteria to mind-independence and by also considering dispositions and historical relations of the bearers of boundaries, instead of only considering their spatio-structural properties, we demonstrate with various examples that spatio-structurally fiat boundaries can nevertheless be mind-independent and in this sense bona fide.We argue that the ontological status of a given boundary is perspective-dependent and that the strictly spatio-structural demarcation criteria follow a static perspective that is ignorant of causality and the dynamics of reality. Based on a distinction of several ontologically independent perspectives, we suggest different types of boundaries and corresponding material entities, including boundaries based on function (locomotion, physiology, ecology, development, reproduction and common history

We construct rigidly supersymmetric bulk-plus-boundary actions, both in x-space and in superspace. For each standard supersymmetric bulk action a minimal supersymmetric bulk-plus-boundary action follows from an extended F- or D-term formula. Additional separately supersymmetric boundary actions can be systematically constructed using co-dimension one multiplets (boundary superfields). We also discuss the orbit of boundary conditions which follow from the Euler-Lagrange variational principle. (orig.)

This article is a retrospective review of patients who presented to Martin Luther King, Jr./Drew Medical Center with gunshot wounds and had either isolated or associated injuries to the hand. The following is an account of those injuries noting the location, soft-tissue or bony involvement, and interventional methods that were implemented in the treatment of these patients who resided primarily in South Central Los Angeles. Prompt evaluation and initiation of treatment is essential in the management of both high- and low-velocity gunshot wounds so as to decrease the potential morbidity that often follows. Society must also look at the prevalence of these injuries and address the underlying issues that often are the root of the acts of violence.

Boundary Region Detection for Continuous Objects in Wireless Sensor Networks

Directory of Open Access Journals (Sweden)

Yaqiang Zhang

2018-01-01

Full Text Available Industrial Internet of Things has been widely used to facilitate disaster monitoring applications, such as liquid leakage and toxic gas detection. Since disasters are usually harmful to the environment, detecting accurate boundary regions for continuous objects in an energy-efficient and timely fashion is a long-standing research challenge. This article proposes a novel mechanism for continuous object boundary region detection in a fog computing environment, where sensing holes may exist in the deployed network region. Leveraging sensory data that have been gathered, interpolation algorithms have been applied to estimate sensory data at certain geographical locations, in order to estimate a more accurate boundary line. To examine whether estimated sensory data reflect that fact, mobile sensors are adopted to traverse these locations for gathering their sensory data, and the boundary region is calibrated accordingly. Experimental evaluation shows that this technique can generate a precise object boundary region with certain time constraints, and the network lifetime can be prolonged significantly.

Convective instability in a time-dependent buoyancy driven boundary layer

The stability of the parallel time-dependent boundary layer adjacent to a suddenly heated vertical wall is described. The flow is investigated through experiments in water, through direct numerical simulation and also through linear stability analysis. The full numerical simulation of the flow shows that small perturbations to the wall boundary conditions, that are also present in the experimental study, are responsible for triggering the instability. As a result, oscillatory behaviour in the boundary layer is observed well before the transition to a steady two-dimensional flow begins. The properties of the observed oscillations are compared with those predicted by a linear stability analysis of the unsteady boundary layer using a quasi-stationary assumption and also using non-stationary assumptions by the formulation of parabolized equations (PSE).

Einstein-Gauss-Bonnet theory of gravity: The Gauss-Bonnet-Katz boundary term

Science.gov (United States)

Deruelle, Nathalie; Merino, Nelson; Olea, Rodrigo

2018-05-01

We propose a boundary term to the Einstein-Gauss-Bonnet action for gravity, which uses the Chern-Weil theorem plus a dimensional continuation process, such that the extremization of the full action yields the equations of motion when Dirichlet boundary conditions are imposed. When translated into tensorial language, this boundary term is the generalization to this theory of the Katz boundary term and vector for general relativity. The boundary term constructed in this paper allows to deal with a general background and is not equivalent to the Gibbons-Hawking-Myers boundary term. However, we show that they coincide if one replaces the background of the Katz procedure by a product manifold. As a first application we show that this Einstein Gauss-Bonnet Katz action yields, without any extra ingredients, the expected mass of the Boulware-Deser black hole.

The Treatment of Violence in Martin Amis’ Money and Pinters’ The Caretaker

Directory of Open Access Journals (Sweden)

Almasa Mulalic

2015-07-01

Full Text Available Towards the end of 1960s there was a huge hippie movement which was marked as Turbulent Decade. In Britain the labor party gained power in 1964, in France the protests in 1968 forced president Charles de Gaulle to leave the country. For some people in Europe, May 1968 meant the end of traditional collective action and the beginning of a new era to be dominated mainly by different social movement emerging at that time throughout the world (Brinkley, 1997; Erlanger, 2008. Harold Pinter’s The Caretaker (1960 and Martin Amis’ Money: The Suicide Note (1984 are embedded with violence and mistreatement among the main characters. With an attempt to reflect social dimensions of the society of that time, both novels deal with violence between very close people who have family or very close friendship ties. The Cartaker is the play in which people are portrayed as living on the edge, and are ready to accept any possibility at presented in order to fulfill their individual psychological needs. The Money is a novel about John Self, a film director, a man who makes deals, spends a lot of money, abuses alcohol, tobacco, pills, pornography, and as a result he is portrayed as extremely violent. This paper attempts to analyze the question of violence that is presented and described in these two works. More importantly, this paper uses socio-psychological approaches and the historical context in analyzing violence in these two works. An analysis of absurd and satirist worlds presented by Pinter and Amis is especially valuable because of their relevance for describing and tackling present-day violence in our societies.

Grain boundary structure and properties

International Nuclear Information System (INIS)

Balluffi, R.W.

1979-01-01

An attempt is made to distinguish those fundamental aspects of grain boundaries which should be relevant to the problem of the time dependent fracture of high temperature structural materials. These include the basic phenomena which are thought to be associated with cavitation and cracking at grain boundaries during service and with the more general microstructural changes which occur during both processing and service. A very brief discussion of the current state of our knowledge of these fundamentals is given. Included are the following: (1) structure of ideal perfect boundaries; (2) defect structure of grain boundaries; (3) diffusion at grain boundaries; (4) grain boundaries as sources/sinks for point defects; (5) grain boundary migration; (6) dislocation phenomena at grain boundaries; (7) atomic bonding and cohesion at grain boundaries; (8) non-equilibrium properties of grain boundaries; and (9) techniques for studying grain boundaries

A novel derivation of the boundary term for the action in Lanczos-Lovelock gravity

Chakraborty, Sumanta; Parattu, Krishnamohan; Padmanabhan, T.

2017-09-01

We present a novel derivation of the boundary term for the action in Lanczos-Lovelock gravity, starting from the boundary contribution in the variation of the Lanczos-Lovelock action. The derivation presented here is straightforward, i.e., one starts from the Lanczos-Lovelock action principle and the action itself dictates the boundary structure and hence the boundary term one needs to add to the action to make it well-posed. It also gives the full structure of the contribution at the boundary of the complete action, enabling us to read off the degrees of freedom to be fixed at the boundary, their corresponding conjugate momenta and the total derivative contribution on the boundary. We also provide a separate derivation of the Gauss-Bonnet case.

Interfaces are a critical determinant of the full range of materials properties, especially at the nanoscale. Computational and experimental methods developed a comprehensive understanding of nanograin evolution based on a fundamental understanding of internal interfaces in nanocrystalline nickel. It has recently been shown that nanocrystals with a bi-modal grain-size distribution possess a unique combination of high-strength, ductility and wear-resistance. We performed a combined experimental and theoretical investigation of the structure and motion of internal interfaces in nanograined metal and the resulting grain evolution. The properties of grain boundaries are computed for an unprecedented range of boundaries. The presence of roughening transitions in grain boundaries is explored and related to dramatic changes in boundary mobility. Experimental observations show that abnormal grain growth in nanograined materials is unlike conventional scale material in both the level of defects and the formation of unfavored phases. Molecular dynamics simulations address the origins of some of these phenomena.

Critical effects of downstream boundary conditions on vortex breakdown

1992-01-01

The unsteady, compressible, full Navier-Stokes (NS) equations are used to study the critical effects of the downstream boundary conditions on the supersonic vortex breakdown. The present study is applied to two supersonic vortex breakdown cases. In the first case, quasi-axisymmetric supersonic swirling flow is considered in a configured circular duct, and in the second case, quasi-axisymmetric supersonic swirling jet, that is issued from a nozzle into a supersonic jet of lower Mach number, is considered. For the configured duct flow, four different types of downstream boundary conditions are used, and for the swirling jet flow from the nozzle, two types of downstream boundary conditions are used. The solutions are time accurate which are obtained using an implicit, upwind, flux-difference splitting, finite-volume scheme.

Social Entrepreneurship: Definition and Boundaries

Samer Abu-Saifan

2012-02-01

Full Text Available While individuals may be publicly recognized as social entrepreneurs for their contributions to improve the welfare of communities, the field of social entrepreneurship continues to struggle to gain academic legitimacy. Social entrepreneurship is a term in search of a good definition. The current use of the term seems vague and limitless; it needs boundaries to demarcate its function. The lack of a common definition hinders research and raises questions about which social or profit-making activities fall within the spectrum of social entrepreneurship. To become an important stream in the entrepreneurship literature, social entrepreneurship needs to be properly defined and it requires a theoretical framework that links it to the theory of entrepreneurship. This article builds on the literature to define social entrepreneurship, discusses the boundaries of socially-oriented entrepreneurial activities, and positions the social entrepreneur in the spectrum of entrepreneurship.

Writing 'new' decalogues: Martin Luther’s development of the Pauline-Augustinian tradition of natural law

Directory of Open Access Journals (Sweden)

A. Raath

2005-07-01

Full Text Available This essay argues in favour of Martin Luther subscribing to the theory of natural law in his theology. An in-depth study of Luther’s views on natural law finds support for Brown’s thesis that Luther’s contribution to the tradition of natural law cannot be taken to form the basis of the theory of divine right prominent in the seventeenth century. Without venturing into the debate on natural law versus legal positivism, it is found that the perspective emanating from Luther’s natural law theory has an important political message for mankind as a whole in its implicit warning against positivistic and legalistic perspectives on law because these are apt to lead to confusion, relativism and historicism. Man, according to Luther’s view, therefore, has to revert to more fundamental principles (or values, representative of “ideal,” “good,” or “true,” norms for testing manmade law. The more specific implications of Luther’s views on natural law for Christians concern an eschatological vision of Christians’ involvement and work in God’s creation. This vision concerns man’s divine appointment to hold office and promote peace in society, and to contribute humbly towards God’s involvement in societies suffering from the effects of legalism or torn apart by conflict.

Optimal boundary control and boundary stabilization of hyperbolic systems

CERN Document Server

Gugat, Martin

2015-01-01

This brief considers recent results on optimal control and stabilization of systems governed by hyperbolic partial differential equations, specifically those in which the control action takes place at the boundary.  The wave equation is used as a typical example of a linear system, through which the author explores initial boundary value problems, concepts of exact controllability, optimal exact control, and boundary stabilization.  Nonlinear systems are also covered, with the Korteweg-de Vries and Burgers Equations serving as standard examples.  To keep the presentation as accessible as possible, the author uses the case of a system with a state that is defined on a finite space interval, so that there are only two boundary points where the system can be controlled.  Graduate and post-graduate students as well as researchers in the field will find this to be an accessible introduction to problems of optimal control and stabilization.

Levels of insecticide resistance to deltamethrin, malathion, and temephos, and associated mechanisms in Aedes aegypti mosquitoes from the Guadeloupe and Saint Martin islands (French West Indies).

In the Guadeloupe and Saint Martin islands, Aedes aegypti mosquitoes are the only recognized vectors of dengue, chikungunya, and Zika viruses. For around 40 years, malathion was used as a mosquito adulticide and temephos as a larvicide. Since the European Union banned the use of these two insecticide molecules in the first decade of the 21st century, deltamethrin and Bacillus thuringiensis var. israelensis are the remaining adulticide and larvicide, respectively, used in Guadeloupe. In order to improve the management of vector control activities in Guadeloupe and Saint Martin, we investigated Ae. aegypti resistance to and mechanisms associated with deltamethrin, malathion, and temephos. Ae. aegypti mosquitoes were collected from six different localities of Guadeloupe and Saint Martin. Larvae were used for malathion and temephos bioassays, and adult mosquitoes for deltamethrin bioassays, following World Health Organization recommendations. Knockdown resistance (Kdr) genotyping for V1016I and F1534C mutations, and expression levels of eight enzymes involved in detoxification mechanisms were examined in comparison with the susceptible reference Bora Bora strain. Resistance ratios (RR 50 ) calculated for Ae. aegypti larvae showed high resistance levels to temephos (from 8.9 to 33.1-fold) and low resistance levels to malathion (from 1.7 to 4.4-fold). Adult females displayed moderate resistance levels to deltamethrin regarding the time necessary to affect 50% of individuals, varying from 8.0 to 28.1-fold. Molecular investigations on adult mosquitoes showed high resistant allele frequencies for V1016I and F1534C (from 85 to 96% and from 90 to 98%, respectively), as well as an overexpression of the glutathione S-transferase gene, GSTe2, the carboxylesterase CCEae3a, and the cytochrome genes 014614, CYP6BB2, CYP6M11, and CYP9J23. Ae. aegypti populations from Guadeloupe and Saint Martin exhibit multiple resistance to organophosphates (temephos and malathion), and

Edgardo Rebagliati Martins Hospital of the Peruvian Institute of Social Security started its activities in 1957, as the largest metropolitan general hospital for the insured workers of the I.P.S.S. At present, it has 1350 hospital beds, attends 36,600 external consults per month, about 10,700 x-rays examinations, as well as 16,800 radiotherapy treatments monthly. 200 brachytherapies with Cesium or Radium are performed annually, besides many other (examinations) imaging exams that use ionizing radiation are carried out by our radiology staff with diagnosis or therapeutic purposes. This is the reason why the hospital directory sent some staff physicians abroad to learn all about radiation protection in a hospital setting, so that they will be able to organize a Radiation Protection Committee to advise and to set up rules and regulations to protect exposed personnel, as well as public in general, improving quality and, consequently, saving costs to the institution. The Constitution of the Radiation Protection Committee, its importance in a medical institution, is informed, and finally its experiences of the every day work and how to act in hospital accidents where ionizing radiation is involved, are transmitted.

Jean-Martin Charcot and Parkinson's disease: Teaching and teaching materials.

Science.gov (United States)

Walusinski, O

2018-04-10

James Parkinson's 1817 seminal article was not well known in France until 1861, when Jean-Martin Charcot and his friend, Alfred Vulpian, published a detailed description in French of paralysis agitans. Their article provided clinical information to help French physicians make an accurate diagnosis by considering gait, shaking and rigidity as well as masked facies. As Charcot always had a strong desire to teach, this article describes his lessons on Parkinson's disease from 1868 to 1888, and also examines the teaching approach he used to pass on his latest findings to his students and colleagues. Charcot also used his role as thesis advisor to disseminate Parkinson's work, and seven of the theses he oversaw, which until now have been overlooked, reveal another facet of his teacher-student relationship. These dissertations provided Charcot with an opportunity to highlight what he had already identified concerning what is today referred to as 'Parkinson-plus syndromes'. Finally, this report concludes with an historical survey of the teaching materials that Paul Richer and Albert Londe developed for the Master at La Salpêtrière to provide him with visual documentation.

2015-08-01

Full Text Available A study of the environmental impacts on the coral resources in the vicinity of the Saint Martin Island Bangladesh was conducted with a view to making an assessment of the current status of coral resources in the island and identifying major natural and anthropogenic environmental threats to the future sustainability of these resources. It is evident that the coral resources have been reduced significantly and currently only 41 coral species are available. The existing environmental condition assessed by pH salinity turbidity and temperature in the island is not found responsible for the survival of the corals. The study also reveals that the major anthropogenic interventions are responsible for the gradual depletion of the coral resources. The major anthropogenic threats to the coral resources are coral collection and overfishing. In addition coral extraction is identified as a potential threat to the future integrity of coral communities in the island. Environmental threats from anthropogenic activities related to sedimentation land erosion and pollution are also the concerns for the coral communities in the island. For the conservation of the coral population no coral monitoring cell has been established in this island.

Paredes, Pedro; Choudhari, Meelan M.; Li, Fei; Chang, Chau-Lyan

2016-01-01

The linear form of the parabolized linear stability equations is used in a variational approach to extend the previous body of results for the optimal, nonmodal disturbance growth in boundary-layer flows. This paper investigates the optimal growth characteristics in the hypersonic Mach number regime without any high-enthalpy effects. The influence of wall cooling is studied, with particular emphasis on the role of the initial disturbance location and the value of the spanwise wave number that leads to the maximum energy growth up to a specified location. Unlike previous predictions that used a basic state obtained from a self-similar solution to the boundary-layer equations, mean flow solutions based on the full Navier-Stokes equations are used in select cases to help account for the viscous- inviscid interaction near the leading edge of the plate and for the weak shock wave emanating from that region. Using the full Navier-Stokes mean flow is shown to result in further reduction with Mach number in the magnitude of optimal growth relative to the predictions based on the self-similar approximation to the base flow.

The metazoan genome is compartmentalized in areas of highly interacting chromatin known as topologically associating domains (TADs). TADs are demarcated by boundaries mostly conserved across cell types and even across species. However, a genome-wide characterization of TAD boundary strength in mammals is still lacking. In this study, we first use fused two-dimensional lasso as a machine learning method to improve Hi-C contact matrix reproducibility, and, subsequently, we categorize TAD boundaries based on their insulation score. We demonstrate that higher TAD boundary insulation scores are associated with elevated CTCF levels and that they may differ across cell types. Intriguingly, we observe that super-enhancers are preferentially insulated by strong boundaries. Furthermore, we demonstrate that strong TAD boundaries and super-enhancer elements are frequently co-duplicated in cancer patients. Taken together, our findings suggest that super-enhancers insulated by strong TAD boundaries may be exploited, as a functional unit, by cancer cells to promote oncogenesis.

Full Text Available Despite heavy pressure and disturbance, state property regimes have stemmed deforestation within protected areas of the West Mengo region of Uganda for over 50 yr. In this manuscript, we reconstruct the process of creation and maintenance of forest reserve boundaries in the West Mengo region of Uganda to identify why these boundaries have largely remained stable over the long term under conditions in which they may be predicted to fail. The dramatic boundary stability in West Mengo we attribute to key aspects of institutional design and enforcement of boundaries.

Full Text Available The fractional Riccati expansion method is used to solve fractional differential equations with variable coefficients. To illustrate the effectiveness of the method, the moving boundary space-time fractional Burger’s equation is studied. The obtained solutions include generalized trigonometric and hyperbolic function solutions. Among these solutions, some are found for the first time. The linear and periodic moving boundaries for the kink solution of the Burger’s equation are presented graphically and discussed.

A Method for Extracting Road Boundary Information from Crowdsourcing Vehicle GPS Trajectories

Full Text Available Crowdsourcing trajectory data is an important approach for accessing and updating road information. In this paper, we present a novel approach for extracting road boundary information from crowdsourcing vehicle traces based on Delaunay triangulation (DT. First, an optimization and interpolation method is proposed to filter abnormal trace segments from raw global positioning system (GPS traces and interpolate the optimization segments adaptively to ensure there are enough tracking points. Second, constructing the DT and the Voronoi diagram within interpolated tracking lines to calculate road boundary descriptors using the area of Voronoi cell and the length of triangle edge. Then, the road boundary detection model is established integrating the boundary descriptors and trajectory movement features (e.g., direction by DT. Third, using the boundary detection model to detect road boundary from the DT constructed by trajectory lines, and a regional growing method based on seed polygons is proposed to extract the road boundary. Experiments were conducted using the GPS traces of taxis in Beijing, China, and the results show that the proposed method is suitable for extracting the road boundary from low-frequency GPS traces, multi-type road structures, and different time intervals. Compared with two existing methods, the automatically extracted boundary information was proved to be of higher quality.

Results obtained from iterative solutions of inviscid and boundary-layer equations are presented and compared with experimental values. The calculated results were obtained with an Euler code and a transonic potential code in order to furnish solutions for the inviscid flow; they were interacted with solutions of two-dimensional boundary-layer equations having a strip-theory approximation. Euler code results are found to be in better agreement with the experimental data than with the full potential code, especially in the presence of shock waves, (with the sole exception of the near-tip region).

Active Boundary Layer Control on a Highly Loaded Turbine Exit Case Profile

Directory of Open Access Journals (Sweden)

Julia Kurz

2018-03-01

Full Text Available A highly loaded turbine exit guide vane with active boundary layer control was investigated experimentally in the High Speed Cascade Wind Tunnel at the University of the German Federal Armed Forces, Munich. The experiments include profile Mach number distributions, wake traverse measurements as well as boundary layer investigations with a flattened Pitot probe. Active boundary layer control by fluidic oscillators was applied to achieve improved performance in the low Reynolds number regime. Low solidity, which can be applied to reduce the number of blades, increases the risk of flow separation resulting in increased total pressure losses. Active boundary layer control is supposed to overcome these negative effects. The experiments show that active boundary layer control by fluidic oscillators is an appropriate way to suppress massive open separation bubbles in the low Reynolds number regime.

Borders, boundaries and desirable wishes

Full Text Available “Borders, boundaries and desirable wishes” is the title of the residential workshop offered to a group of young adults (aged 18-25 of the Centro di Salute Mentale (Mental Health Center of the DSM Basaglia of ASL TO2 in Turin. The idea of the workshop, the definition of the objectives and the topics, which are clearly expressed in the title, come from the work of the team dedicated to group psychotherapies, which has been offering group psychodrama sessions to young adults of this age since 2008. In the delicate move to the adult age, these young adults are lost and stuck in static realities where it is not possible to open up to the dimension of desire nor to the transforming encounter with the Other, since they didn’t have the experience of boundaries and lack. These two elements are necessary to acquire the ability to make projects for oneself. During the workshop the following instruments were used: group, psychodrama and art therapy. The group, as a paternal function, ensured the presence of safe boundaries enabling individuals to experiment; psychodrama and art therapy enabled the bodies to experience encounters and transformations, using doing as a metaphor for the movement against the inhibition of doing and as a way to show oneself to the Other and be able to see the Other.

2014-01-01

Full Text Available An analysis is carried out to investigate the influence of variable thermal conductivity and partial velocity slip on hydromagnetic two-dimensional boundary layer flow of a nanofluid with Cu nanoparticles over a stretching sheet with convective boundary condition. Using similarity transformation, the governing boundary layer equations along with the appropriate boundary conditions are transformed to a set of ordinary differential equations. Employing Runge-kutta fourth-order method along with shooting technique, the resultant system of equations is solved. The influence of various pertinent parameters such as nanofluid volume fraction parameter, the magnetic parameter, radiation parameter, thermal conductivity parameter, velocity slip parameter, Biot number, and suction or injection parameter on the velocity of the flow field and heat transfer characteristics is computed numerically and illustrated graphically. The present results are compared with the existing results for the case of regular fluid and found an excellent agreement.

Making Boundaries Great Again: Essentialism and Support for Boundary-Enhancing Initiatives.

Science.gov (United States)

Roberts, Steven O; Ho, Arnold K; Rhodes, Marjorie; Gelman, Susan A

2017-12-01

Psychological essentialism entails a focus on category boundaries (e.g., categorizing people as men or women) and an increase in the conceptual distance between those boundaries (e.g., accentuating the differences between men and women). Across eight studies, we demonstrate that essentialism additionally entails an increase in support for boundary-enhancing legislation, policies, and social services, and that it does so under conditions that disadvantage social groups, as well as conditions that benefit them. First, individual differences in essentialism were associated with support for legislation mandating that transgender people use restrooms corresponding with their biological sex, and with support for the boundary-enhancing policies of the 2016 then-presumptive Republican presidential nominee (i.e., Donald Trump). Second, essentialism was associated with support for same-gender classrooms designed to promote student learning, as well as support for services designed to benefit LGBTQ (lesbian, gay, bisexual, transgender, queer) individuals. These findings demonstrate the boundary-enhancing implications of essentialism and their social significance.

The Boundary Function Method. Fundamentals

Science.gov (United States)

Kot, V. A.

2017-03-01

The boundary function method is proposed for solving applied problems of mathematical physics in the region defined by a partial differential equation of the general form involving constant or variable coefficients with a Dirichlet, Neumann, or Robin boundary condition. In this method, the desired function is defined by a power polynomial, and a boundary function represented in the form of the desired function or its derivative at one of the boundary points is introduced. Different sequences of boundary equations have been set up with the use of differential operators. Systems of linear algebraic equations constructed on the basis of these sequences allow one to determine the coefficients of a power polynomial. Constitutive equations have been derived for initial boundary-value problems of all the main types. With these equations, an initial boundary-value problem is transformed into the Cauchy problem for the boundary function. The determination of the boundary function by its derivative with respect to the time coordinate completes the solution of the problem.

Circular resistor networks for electrical impedance tomography with partial boundary measurements

International Nuclear Information System (INIS)

Borcea, L; Mamonov, A V; Druskin, V

2010-01-01

We introduce an algorithm for the numerical solution of electrical impedance tomography (EIT) in two dimensions, with partial boundary measurements. The algorithm is an extension of the one in Borcea et al (2008 Inverse Problems 24 035013 (31pp)) and Vasquez (2006 PhD Thesis Rice University, Houston, TX, USA) for EIT with full boundary measurements. It is based on resistor networks that arise in finite volume discretizations of the elliptic partial differential equation for the potential on so-called optimal grids that are computed as part of the problem. The grids are adaptively refined near the boundary, where we measure and expect better resolution of the images. They can be used very efficiently in inversion, by defining a reconstruction mapping that is an approximate inverse of the forward map, and acts therefore as a preconditioner in any iterative scheme that solves the inverse problem via optimization. The main result in this paper is the construction of optimal grids for EIT with partial measurements by extremal quasiconformal (Teichmüller) transformations of the optimal grids for EIT with full boundary measurements. We present the algorithm for computing the reconstruction mapping on such grids, and we illustrate its performance with numerical simulations. The results show an interesting trade-off between the resolution of the reconstruction in the domain of the solution and distortions due to artificial anisotropy induced by the distribution of the measurement points on the accessible boundary

EXTRACTION OF BUILDING BOUNDARY LINES FROM AIRBORNE LIDAR POINT CLOUDS

Directory of Open Access Journals (Sweden)

Y.-H. Tseng

2016-10-01

Full Text Available Building boundary lines are important spatial features that characterize the topographic maps and three-dimensional (3D city models. Airborne LiDAR Point clouds provide adequate 3D spatial information for building boundary mapping. However, information of boundary features contained in point clouds is implicit. This study focuses on developing an automatic algorithm of building boundary line extraction from airborne LiDAR data. In an airborne LiDAR dataset, top surfaces of buildings, such as roofs, tend to have densely distributed points, but vertical surfaces, such as walls, usually have sparsely distributed points or even no points. The intersection lines of roof and wall planes are, therefore, not clearly defined in point clouds. This paper proposes a novel method to extract those boundary lines of building edges. The extracted line features can be used as fundamental data to generate topographic maps of 3D city model for an urban area. The proposed method includes two major process steps. The first step is to extract building boundary points from point clouds. Then the second step is followed to form building boundary line features based on the extracted boundary points. In this step, a line fitting algorithm is developed to improve the edge extraction from LiDAR data. Eight test objects, including 4 simple low buildings and 4 complicated tall buildings, were selected from the buildings in NCKU campus. The test results demonstrate the feasibility of the proposed method in extracting complicate building boundary lines. Some results which are not as good as expected suggest the need of further improvement of the method.

Well-established aspects of grain-boundary migration are first briefly reviewed (influences of driving force, temperature, orientation and foreign atoms). Recent developments of the experimental methods and results are then examined, by considering the various driving of resistive forces acting on grain boundaries. Finally, the evolution in the theoretical models of grain-boundary motion is described, on the one hand for ideally pure metals and, on the other hand, in the presence of solute impurity atoms [fr

Besides, we give the convergence of this new method.

Grain Boundary Segregation in Metals

CERN Document Server

Lejcek, Pavel

2010-01-01

Grain boundaries are important structural components of polycrystalline materials used in the vast majority of technical applications. Because grain boundaries form a continuous network throughout such materials, their properties may limit their practical use. One of the serious phenomena which evoke these limitations is the grain boundary segregation of impurities. It results in the loss of grain boundary cohesion and consequently, in brittle fracture of the materials. The current book deals with fundamentals of grain boundary segregation in metallic materials and its relationship to the grain boundary structure, classification and other materials properties.

Full Text Available The aim of this paper is to show boundaries between fair and harmful tax competition. The author analyses OECD’s reports and literature related to the tax competition. In the beginning, the author presents the notion of tax competition and its division into fair and unfair tax competition. Differences between tax heaven and preferential tax regime are also discussed. In the summary, the author highlights that boundaries between fair and harmful tax competition are not obvious, but there are well-known guidelines, which let distinguish above-mentioned issues. The author considers that there are real tax burden, effective exchange of tax information and transparency in the fair tax regime. The author states that taxpayer can do justified tax planning in such tax system.

Stability and Bifurcation of a Fishery Model with Crowley-Martin Functional Response

Science.gov (United States)

Maiti, Atasi Patra; Dubey, B.

To understand the dynamics of a fishery system, a nonlinear mathematical model is proposed and analyzed. In an aquatic environment, we considered two populations: one is prey and another is predator. Here both the fish populations grow logistically and interaction between them is of Crowley-Martin type functional response. It is assumed that both the populations are harvested and the harvesting effort is assumed to be dynamical variable and tax is considered as a control variable. The existence of equilibrium points and their local stability are examined. The existence of Hopf-bifurcation, stability and direction of Hopf-bifurcation are also analyzed with the help of Center Manifold theorem and normal form theory. The global stability behavior of the positive equilibrium point is also discussed. In order to find the value of optimal tax, the optimal harvesting policy is used. To verify our analytical findings, an extensive numerical simulation is carried out for this model system.

Accuracy of multi-point boundary crossing time analysis

Directory of Open Access Journals (Sweden)

J. Vogt

2011-12-01

Full Text Available Recent multi-spacecraft studies of solar wind discontinuity crossings using the timing (boundary plane triangulation method gave boundary parameter estimates that are significantly different from those of the well-established single-spacecraft minimum variance analysis (MVA technique. A large survey of directional discontinuities in Cluster data turned out to be particularly inconsistent in the sense that multi-point timing analyses did not identify any rotational discontinuities (RDs whereas the MVA results of the individual spacecraft suggested that RDs form the majority of events. To make multi-spacecraft studies of discontinuity crossings more conclusive, the present report addresses the accuracy of the timing approach to boundary parameter estimation. Our error analysis is based on the reciprocal vector formalism and takes into account uncertainties both in crossing times and in the spacecraft positions. A rigorous error estimation scheme is presented for the general case of correlated crossing time errors and arbitrary spacecraft configurations. Crossing time error covariances are determined through cross correlation analyses of the residuals. The principal influence of the spacecraft array geometry on the accuracy of the timing method is illustrated using error formulas for the simplified case of mutually uncorrelated and identical errors at different spacecraft. The full error analysis procedure is demonstrated for a solar wind discontinuity as observed by the Cluster FGM instrument.

Siriwitpreecha, A.; Onjun, T.; Suwanna, S.; Poolyarat, N.; Picha, R.

2009-07-01

Full text: The models for predicting temperature and density of ions and electrons at boundary conditions in L-mode tokamak plasma are developed using an empirical approach and optimized against the experimental data obtained from the latest public version of the International Pedestal Database (version 3.2). It is assumed that the temperature and density at boundary of L-mode plasma are functions of engineering parameters such as plasma current, toroidal magnetic field, total heating power, line averaged density, hydrogenic particle mass (A H ), major radius, minor radius, and elongation at the separatrix. Multiple regression analysis is carried out for these parameters with 86 data points in L-mode from Aug (61) and JT60U (25). The RMSE of temperature and density at boundary of L-mode plasma are found to be 24.41% and 18.81%, respectively. These boundary models are implemented in BALDUR code, which will be used to simulate the L-mode plasma in the tokamak

Full Text Available Objective: The present study aimed at examining the effect of multidimensional motivation interventions based on Martin's model on cognitive and behavioral components of motivation.Methods: The research design was prospective with pretest, posttest, and follow-up, and 2 experimental groups. In this study, 90 students (45 participants in the experimental group and 45 in the control group constituted the sample of the study, and they were selected by available sampling method. Motivation interventions were implemented for fifteen 60-minute sessions 3 times a week, which lasted for about 2 months. Data were analyzed using repeated measures multivariate variance analysis test.Results: The findings revealed that multidimensional motivation interventions resulted in a significant increase in the scores of cognitive components such as self-efficacy, mastery goal, test anxiety, and feeling of lack of control, and behavioral components such as task management. The results of one-month follow-up indicated the stability of the created changes in test anxiety and cognitive strategies; however, no significant difference was found between the 2 groups at the follow-up in self-efficacy, mastery goals, source of control, and motivation.Conclusions: The research evidence indicated that academic motivation is a multidimensional component and is affected by cognitive and behavioral factors; therefore, researchers, teachers, and other authorities should attend to these factors to increase academic motivation.

Subgroup report on grain boundary and interphase boundary structure and properties

In many high temperature structural applications, the performance characteristics of a materials system are largely controlled by the properties of its grain and interphase boundaries. Failure in creep and fatigue frequently occurs by cavitation, or cracking along grain boundaries. In a few special cases, this failure problem has been overcome by directional alignment of grain and interphase boundaries by various types of metallurgical processing such as directional solidification and directional recrystallization. A good example is to be found in the application of directionally aligned structures in high performance gas-turbine airfoils. However, where fine, equiaxed grain structures are desirable, other methods of controlling grain boundary properties have been developed. Important among these has been the introduction of improvements in primary melting practices, designed to control important impurities. This is of decisive importance because even traces of certain impurity elements present in grain boundaries in high temperature materials can seriously affect properties. Impurities are deleterious and need to be removed. However, in certain cases, (e.g., creep fracture) controlled impurity additions can be beneficial and result in improved properties

«Il nastro a rovescio». Possibili influenze di Storie Naturali ne La freccia del tempo di Martin Amis

Giuseppe Alvino

2016-11-01

Full Text Available Il presente contributo si propone di ripercorrere le tappe del rapporto letterario tra Martin Amis e Primo Levi, sottolineando l’attenzione dello scrittore inglese nei confronti dei testi di Levi. Come Amis stesso scrive più volte, Levi fu per lui una delle letture fondamentali nel suo percorso di ricerca letteraria; e nella Postfazione di una delle sue opere principali, Time’s arrow (La freccia del tempo, l’autore richiama per ben due volte l’attenzione su Levi, da un lato, ritenendo che senza le letture leviane non avrebbe potuto scrivere il suo romanzo, e dall’altro, avvertendo il lettore che il titolo pensato originariamente era un’espressione leviana, La natura dell’offesa (oggi secondo titolo de La freccia del tempo. Partendo da questi presupposti si nota come, nel racconto Trattamento di quiescenza della raccolta Storie Naturali, Levi parla tangenzialmente di uno scorrere del tempo al contrario e con una causalità inversa, nello stesso modo in cui Amis, in maniera più sistematica e precisa, costruisce per intero il suo romanzo. Dunque si potrebbe ipotizzare che Amis si sia ispirato non solo al Levi di Se questo è un uomo, La tregua e I sommersi e i salvati per il tema del suo romanzo (e cioè la barbarie nazista, ma anche al Levi dei racconti per il modo tutto particolare di narrare la sua storia. Del resto, la scelta di scrivere il romanzo ‘al contrario’ è funzionale al tema: solo in un mondo con un tempo e una causalità ‘al contrario’ la barbarie dei campi di concentramento sarebbe giustificabile. The purpose of this paper is to explore the literary relationship between Martin Amis and Primo Levi, highlighting how the English writer directed his attention to Levi’s works. As Amis himself often writes, Levi was one of his fundamental readings in his literary research; in the Afterword of one of his masterpieces, Time’s Arrow, the author mentions Levi twice: on the one hand, he claims that he could not

Coupled vs. decoupled boundary layers in VOCALS-REx

Directory of Open Access Journals (Sweden)

C. R. Jones

2011-07-01

Full Text Available We analyze the extent of subtropical stratocumulus-capped boundary layer decoupling and its relation to other boundary-layer characteristics and forcings using aircraft observations from VOCALS-REx along a swath of the subtropical southeast Pacific Ocean running west 1600 km from the coast of Northern Chile. We develop two complementary and consistent measures of decoupling. The first is based on boundary layer moisture and temperature stratification in flight profiles from near the surface to above the capping inversion, and the second is based the difference between the lifted condensation level (LCL and a mean lidar-derived cloud base measured on flight legs at 150 m altitude. Most flights took place during early-mid morning, well before the peak in insolation-induced decoupling.

We find that the boundary layer is typically shallower, drier, and well mixed near the shore, and tends to deepen, decouple, and produce more drizzle further offshore to the west. Decoupling is strongly correlated to the "mixed layer cloud thickness", defined as the difference between the capping inversion height and the LCL; other factors such as wind speed, cloud droplet concentration, and inversion thermodynamic jumps have little additional explanatory power. The results are broadly consistent with the deepening-warming theory of decoupling.

In the deeper boundary layers observed well offshore, there was frequently nearly 100 % boundary-layer cloud cover despite pronounced decoupling. The cloud cover was more strongly correlated to a κ parameter related to the inversion jumps of humidity and temperature, though the exact functional relation is slightly different than found in prior large-eddy simulation studies.

Full Text Available We discuss how homology computation can be exploited in computational electromagnetism. We represent various cellular mesh reduction techniques, which enable the computation of generators of homology spaces in an acceptable time. Furthermore, we show how the generators can be used for setting up and analysis of an electromagnetic boundary value problem. The aim is to provide a rationale for homology computation in electromagnetic modeling software.

Exact and Optimal Quantum Mechanics/Molecular Mechanics Boundaries.

Motivated by recent work in density matrix embedding theory, we define exact link orbitals that capture all quantum mechanical (QM) effects across arbitrary quantum mechanics/molecular mechanics (QM/MM) boundaries. Exact link orbitals are rigorously defined from the full QM solution, and their number is equal to the number of orbitals in the primary QM region. Truncating the exact set yields a smaller set of link orbitals optimal with respect to reproducing the primary region density matrix. We use the optimal link orbitals to obtain insight into the limits of QM/MM boundary treatments. We further analyze the popular general hybrid orbital (GHO) QM/MM boundary across a test suite of molecules. We find that GHOs are often good proxies for the most important optimal link orbital, although there is little detailed correlation between the detailed GHO composition and optimal link orbital valence weights. The optimal theory shows that anions and cations cannot be described by a single link orbital. However, expanding to include the second most important optimal link orbital in the boundary recovers an accurate description. The second optimal link orbital takes the chemically intuitive form of a donor or acceptor orbital for charge redistribution, suggesting that optimal link orbitals can be used as interpretative tools for electron transfer. We further find that two optimal link orbitals are also sufficient for boundaries that cut across double bonds. Finally, we suggest how to construct "approximately" optimal link orbitals for practical QM/MM calculations.

Detecting Boundary Nodes and Coverage Holes in Wireless Sensor Networks

Li-Hui Zhao

2016-01-01

Full Text Available The emergence of coverage holes in wireless sensor networks (WSNs means that some special events have broken out and the function of WSNs will be seriously influenced. Therefore, the issues of coverage holes have attracted considerable attention. In this paper, we focus on the identification of boundary nodes and coverage holes, which is crucially important to preventing the enlargement of coverage holes and ensuring the transmission of data. We define the problem of coverage holes and propose two novel algorithms to identify the coverage holes in WSNs. The first algorithm, Distributed Sector Cover Scanning (DSCS, can be used to identify the nodes on hole borders and the outer boundary of WSNs. The second scheme, Directional Walk (DW, can locate the coverage holes based on the boundary nodes identified with DSCS. We implement the algorithms in various scenarios and fully evaluate their performance. The simulation results show that the boundary nodes can be accurately detected by DSCS and the holes enclosed by the detected boundary nodes can be identified by DW. The comparisons confirm that the proposed algorithms outperform the existing ones.

Full Text Available The article refers to the political art scene in Austria during the 1990s and early 2000s. Participatory art-activism projects by the group WochenKlausur and by Martin Krenn and Oliver Ressler are juxtaposed to artistic work used for political activism by the women migrants' organization maiz. All case-studies engage with issues of immigration in Austria, touching also upon official immigration policies and practices in the European Union after 1989. In the case studies the artists transfer political activism practices (giving people a voice to art practices by means of participatory, public art projects, where, for instance, migrants are interviewed. In reverse, the activists transfer artistic practices (e.g., performance to their political activism practices.

Development of boundary layers

International Nuclear Information System (INIS)

Herbst, R.

1980-01-01

Boundary layers develop along the blade surfaces on both the pressure and the suction side in a non-stationary flow field. This is due to the fact that there is a strongly fluctuating flow on the downstream blade row, especially as a result of the wakes of the upstream blade row. The author investigates the formation of boundary layers under non-stationary flow conditions and tries to establish a model describing the non-stationary boundary layer. For this purpose, plate boundary layers are measured, at constant flow rates but different interferent frequency and variable pressure gradients. By introducing the sample technique, measurements of the non-stationary boundary layer become possible, and the flow rate fluctuation can be divided in its components, i.e. stochastic turbulence and periodical fluctuation.

Axisymmetric Tornado Simulations with a Semi-Slip Boundary

Directory of Open Access Journals (Sweden)

Brian H. Fiedler

2017-12-01

Full Text Available The structure of natural tornadoes and simulated analogs are sensitive to the lower boundary condition for friction. Three-dimensional numerical simulations of storms require a choice for turbulence parameterizations and resolution of wind near the lower boundary. This article explores some of the consequences of choices of a surface drag coefficient on the structure of a mature simulated tornado, using a conventional axisymmetric model. The surface drag parameterization is explored over the range of the semi-slip condition, including the extremes of no-slip and free-slip. A moderate semi-slip condition allows for an extreme pressure deficit, but without the unrealistic vortex breakdown of the no-slip condition.

A simple and efficient outflow boundary condition for the incompressible Navier–Stokes equations

Directory of Open Access Journals (Sweden)

Yibao Li

2017-01-01

Full Text Available Many researchers have proposed special treatments for outlet boundary conditions owing to lack of information at the outlet. Among them, the simplest method requires a large enough computational domain to prevent or reduce numerical errors at the boundaries. However, an efficient method generally requires special treatment to overcome the problems raised by the outlet boundary condition used. For example, mass flux is not conserved and the fluid field is not divergence-free at the outlet boundary. Overcoming these problems requires additional computational cost. In this paper, we present a simple and efficient outflow boundary condition for the incompressible Navier–Stokes equations, aiming to reduce the computational domain for simulating flow inside a long channel in the streamwise direction. The proposed outflow boundary condition is based on the transparent equation, where a weak formulation is used. The pressure boundary condition is derived by using the Navier–Stokes equations and the outlet flow boundary condition. In the numerical algorithm, a staggered marker-and-cell grid is used and temporal discretization is based on a projection method. The intermediate velocity boundary condition is consistently adopted to handle the velocity–pressure coupling. Characteristic numerical experiments are presented to demonstrate the robustness and accuracy of the proposed numerical scheme. Furthermore, the agreement of computational results from small and large domains suggests that our proposed outflow boundary condition can significantly reduce computational domain sizes.

Vibration Analysis of Annular Sector Plates under Different Boundary Conditions

Directory of Open Access Journals (Sweden)

Dongyan Shi

2014-01-01

Full Text Available An analytical framework is developed for the vibration analysis of annular sector plates with general elastic restraints along each edge of plates. Regardless of boundary conditions, the displacement solution is invariably expressed as a new form of trigonometric expansion with accelerated convergence. The expansion coefficients are treated as the generalized coordinates and determined using the Rayleigh-Ritz technique. This work allows a capability of modeling annular sector plates under a variety of boundary conditions and changing the boundary conditions as easily as modifying the material properties or dimensions of the plates. Of equal importance, the proposed approach is universally applicable to annular sector plates of any inclusion angles up to 2π. The reliability and accuracy of the current method are adequately validated through numerical examples.

Plasma boundaries at Mars: a 3-D simulation study

Directory of Open Access Journals (Sweden)

A. Bößwetter

2004-12-01

Full Text Available The interaction of the solar wind with the ionosphere of planet Mars is studied using a three-dimensional hybrid model. Mars has only a weak intrinsic magnetic field, and consequently its ionosphere is directly affected by the solar wind. The gyroradii of the solar wind protons are in the range of several hundred kilometers and therefore comparable with the characteristic scales of the interaction region. Different boundaries emerge from the interaction of the solar wind with the continuously produced ionospheric heavy-ion plasma, which could be identified as a bow shock (BS, ion composition boundary (ICB and magnetic pile up boundary (MPB, where the latter both turn out to coincide. The simulation results regarding the shape and position of these boundaries are in good agreement with the measurements made by Phobos-2 and MGS spacecraft. It is shown that the positions of these boundaries depend essentially on the ionospheric production rate, the solar wind ram pressure, and the often unconsidered electron temperature of the ionospheric heavy ion plasma. Other consequences are rays of planetary plasma in the tail and heavy ion plasma clouds, which are stripped off from the dayside ICB region by some instability.

Choice of futility boundaries for group sequential designs with two endpoints

Directory of Open Access Journals (Sweden)

Svenja Schüler

2017-08-01

Full Text Available Abstract Background In clinical trials, the opportunity for an early stop during an interim analysis (either for efficacy or for futility may relevantly save time and financial resources. This is especially important, if the planning assumptions required for power calculation are based on a low level of evidence. For example, when including two primary endpoints in the confirmatory analysis, the power of the trial depends on the effects of both endpoints and on their correlation. Assessing the feasibility of such a trial is therefore difficult, as the number of parameter assumptions to be correctly specified is large. For this reason, so-called ‘group sequential designs’ are of particular importance in this setting. Whereas the choice of adequate boundaries to stop a trial early for efficacy has been broadly discussed in the literature, the choice of optimal futility boundaries has not been investigated so far, although this may have serious consequences with respect to performance characteristics. Methods In this work, we propose a general method to construct ‘optimal’ futility boundaries according to predefined criteria. Further, we present three different group sequential designs for two endpoints applying these futility boundaries. Our methods are illustrated by a real clinical trial example and by Monte-Carlo simulations. Results By construction, the provided method of choosing futility boundaries maximizes the probability to correctly stop in case of small or opposite effects while limiting the power loss and the probability of stopping the study ‘wrongly’. Our results clearly demonstrate the benefit of using such ‘optimal’ futility boundaries, especially compared to futility boundaries commonly applied in practice. Conclusions As the properties of futility boundaries are often not considered in practice and unfavorably chosen futility boundaries may imply bad properties of the study design, we recommend assessing the

Response of a Hypersonic Boundary Layer to Freestream Pulse Acoustic Disturbance

Directory of Open Access Journals (Sweden)

Zhenqing Wang

2014-01-01

Full Text Available The response of hypersonic boundary layer over a blunt wedge to freestream pulse acoustic disturbance was investigated. The stability characteristics of boundary layer for freestream pulse wave and continuous wave were analyzed comparatively. Results show that freestream pulse disturbance changes the thermal conductivity characteristics of boundary layer. For pulse wave, the number of main disturbance clusters decreases and the frequency band narrows along streamwise. There are competition and disturbance energy transfer among different modes in boundary layer. The dominant mode of boundary layer has an inhibitory action on other modes. Under continuous wave, the disturbance modes are mainly distributed near fundamental and harmonic frequencies, while under pulse wave, the disturbance modes are widely distributed in different modes. For both pulse and continuous waves, most of disturbance modes slide into a lower-growth or decay state in downstream, which is tending towards stability. The amplitude of disturbance modes in boundary layer under continuous wave is considerably larger than pulse wave. The growth rate for the former is also considerably larger than the later the disturbance modes with higher growth are mainly distributed near fundamental and harmonic frequencies for the former, while the disturbance modes are widely distributed in different frequencies for the latter.

Healing relationships and the existential philosophy of Martin Buber

Science.gov (United States)

Scott, John G; Scott, Rebecca G; Miller, William L; Stange, Kurt C; Crabtree, Benjamin F

2009-01-01

The dominant unspoken philosophical basis of medical care in the United States is a form of Cartesian reductionism that views the body as a machine and medical professionals as technicians whose job is to repair that machine. The purpose of this paper is to advocate for an alternative philosophy of medicine based on the concept of healing relationships between clinicians and patients. This is accomplished first by exploring the ethical and philosophical work of Pellegrino and Thomasma and then by connecting Martin Buber's philosophical work on the nature of relationships to an empirically derived model of the medical healing relationship. The Healing Relationship Model was developed by the authors through qualitative analysis of interviews of physicians and patients. Clinician-patient healing relationships are a special form of what Buber calls I-Thou relationships, characterized by dialog and mutuality, but a mutuality limited by the inherent asymmetry of the clinician-patient relationship. The Healing Relationship Model identifies three processes necessary for such relationships to develop and be sustained: Valuing, Appreciating Power and Abiding. We explore in detail how these processes, as well as other components of the model resonate with Buber's concepts of I-Thou and I-It relationships. The resulting combined conceptual model illuminates the wholeness underlying the dual roles of clinicians as healers and providers of technical biomedicine. On the basis of our analysis, we argue that health care should be focused on healing, with I-Thou relationships at its core. PMID:19678950

Motivation: Reconstructing the full- length expressed transcripts (a. k. a. the transcript assembly problem) from the short sequencing reads produced by RNA-seq protocol plays a central role in identifying novel genes and transcripts as well as in studying gene expressions and gene functions. A crucial step in transcript assembly is to accurately determine the splicing junctions and boundaries of the expressed transcripts from the reads alignment. In contrast to the splicing junctions that can be efficiently detected from spliced reads, the problem of identifying boundaries remains open and challenging, due to the fact that the signal related to boundaries is noisy and weak.

Full Text Available Abdulrahman Saud Al-rasheed Department of Psychology, King Saud University, Riyadh, Kingdom of Saudi Arabia Abstract: Despite a plethora of behavioral research exploring the phenomenon of color categorical perception (CP known as "better discrimination between pair of colors stimuli from different categories and pair of colors stimuli from the same category even when the stimulus differences between the pairs of stimuli are equal", most of the evidence for the CP of color was derived from Roman or top-to-down script readers and very rarely from right-to-left script readers in primary category. To date, no studies of color CP have been conducted on right-to-left script readers in secondary category boundary to support this theory. Three experiments have been conducted: Experiments 1 and 2 established the Arabic blue–purple secondary category boundary, and Experiment 3 tested the CP of color in the blue–purple category boundary. Sixty participants (30 men and 30 women took part in this study. All spoke Arabic as their first language, and all were undergraduate or postgraduate students at King Saud University. Their ages ranged from 18–35 years with a mean age of 21.9 years (SD =5.2. The result indicated that for Experiments 1 and 2, it appeared that the Arabic blue–purple category boundary was approximately 10PB and it is in the same location as for English. For Experiment 3, reaction times in the between-categories condition were significantly faster than those in the within-category condition; this suggested that CP of color was shown in the Arabic's blue–purple secondary category boundary.

Jeff Foxworthy’s Redneck Humor and the Boundaries of Middle-Class American Whiteness

Directory of Open Access Journals (Sweden)

J. David Thomas

2016-04-01

Full Text Available Recent studies examine the use of rhetorical boundaries to produce intra-racial othering within whiteness. I expand this project by exploring the textual and social codes in Jeff Foxworthy humor that demarcate the boundaries between the redneck and the non-redneck. Such boundaries are complex, porous fault-lines that use symbolic pollution embedded in humor to stigmatize White outsiders. Social codes referencing symbolic pollution establish boundaries to define and insulate a normative, mainstream White identity from the intra-racial threat of redneck identity. This project provides a novel addition to whiteness studies by taking redneck humor analytically seriously and concludes by drawing comparisons between codes found in Foxworthy humor and those levied against rural Whites during the eugenics era.

Exchange Processes in the Atmospheric Boundary Layer Over Mountainous Terrain

Stefano Serafin

2018-03-01

Full Text Available The exchange of heat, momentum, and mass in the atmosphere over mountainous terrain is controlled by synoptic-scale dynamics, thermally driven mesoscale circulations, and turbulence. This article reviews the key challenges relevant to the understanding of exchange processes in the mountain boundary layer and outlines possible research priorities for the future. The review describes the limitations of the experimental study of turbulent exchange over complex terrain, the impact of slope and valley breezes on the structure of the convective boundary layer, and the role of intermittent mixing and wave–turbulence interaction in the stable boundary layer. The interplay between exchange processes at different spatial scales is discussed in depth, emphasizing the role of elevated and ground-based stable layers in controlling multi-scale interactions in the atmosphere over and near mountains. Implications of the current understanding of exchange processes over mountains towards the improvement of numerical weather prediction and climate models are discussed, considering in particular the representation of surface boundary conditions, the parameterization of sub-grid-scale exchange, and the development of stochastic perturbation schemes.

Current Challenges in Understanding and Forecasting Stable Boundary Layers over Land and Ice

Gert-Jan eSteeneveld

2014-10-01

Full Text Available Understanding and prediction of the stable atmospheric boundary layer is challenging. Many physical processes come into play in the stable boundary layer, i.e. turbulence, radiation, land surface coupling and heterogeneity, orographic turbulent and gravity wave drag. The development of robust stable boundary-layer parameterizations for weather and climate models is difficult because of the multiplicity of processes and their complex interactions. As a result, these models suffer from biases in key variables, such as the 2-m temperature, boundary-layer depth and wind speed. This short paper briefly summarizes the state-of-the-art of stable boundary layer research, and highlights physical processes that received only limited attention so far, in particular orographically-induced gravity wave drag, longwave radiation divergence, and the land-atmosphere coupling over a snow-covered surface. Finally, a conceptual framework with relevant processes and particularly their interactions is proposed.

Full Text Available Chemical composition of interfaces—free surfaces and grain boundaries—is generally described by the Langmuir–McLean segregation isotherm controlled by Gibbs energy of segregation. Various components of the Gibbs energy of segregation, the standard and the excess ones as well as other thermodynamic state functions—enthalpy, entropy and volume—of interfacial segregation are derived and their physical meaning is elucidated. The importance of the thermodynamic state functions of grain boundary segregation, their dependence on volume solid solubility, mutual solute–solute interaction and pressure effect in ferrous alloys is demonstrated.

Boundary Associated Long Noncoding RNA Mediates Long-Range Chromosomal Interactions.

Directory of Open Access Journals (Sweden)

Ifeoma Jane Nwigwe

Full Text Available CCCTC binding factor (CTCF is involved in organizing chromosomes into mega base-sized, topologically associated domains (TADs along with other factors that define sub-TAD organization. CTCF-Cohesin interactions have been shown to be critical for transcription insulation activity as it stabilizes long-range interactions to promote proper gene expression. Previous studies suggest that heterochromatin boundary activity of CTCF may be independent of Cohesin, and there may be additional mechanisms for defining topological domains. Here, we show that a boundary site we previously identified known as CTCF binding site 5 (CBS5 from the homeotic gene cluster A (HOXA locus exhibits robust promoter activity. This promoter activity from the CBS5 boundary element generates a long noncoding RNA that we designate as boundary associated long noncoding RNA-1 (blncRNA1. Functional characterization of this RNA suggests that the transcript stabilizes long-range interactions at the HOXA locus and promotes proper expression of HOXA genes. Additionally, our functional analysis also shows that this RNA is not needed in the stabilization of CTCF-Cohesin interactions however CTCF-Cohesin interactions are critical in the transcription of blncRNA1. Thus, the CTCF-associated boundary element, CBS5, employs both Cohesin and noncoding RNA to establish and maintain topologically associated domains at the HOXA locus.

Full Text Available In this study an investigation using log-files of teachers’ Collections of educational resources in two different platforms was conducted. The goal was to find empirical evidence from the field that teachers use and reuse learning resources that are in a language other than their mother tongue and originate from different countries than they do, for this, the term cross-boundary use of learning resources is used. In both contexts behavioural evidence was found that cross-boundary use and reuse takes place, and it was shown that it correlates with the general use and reuse trends. Moreover, it was found that cross-boundary reuse, when compared to 20% of general reuse, was notably less (37% to 55% of it. The motivation to study cross-boundary use and reuse is to set a baseline for future studies, and to understand how it can be supported and enhanced in the future.

An effective absorbing layer for the boundary condition in acoustic seismic wave simulation

Science.gov (United States)

Yao, Gang; da Silva, Nuno V.; Wu, Di

2018-04-01

Efficient numerical simulation of seismic wavefields generally involves truncating the Earth model in order to keep computing time and memory requirements down. Absorbing boundary conditions, therefore, are applied to remove the boundary reflections caused by this truncation, thereby allowing for accurate modeling of wavefields. In this paper, we derive an effective absorbing boundary condition for both acoustic and elastic wave simulation, through the simplification of the damping term of the split perfectly matched layer (SPML) boundary condition. This new boundary condition is accurate, cost-effective, and easily implemented, especially for high-performance computing. Stability analysis shows that this boundary condition is effectively as stable as normal (non-absorbing) wave equations for explicit time-stepping finite differences. We found that for full-waveform inversion (FWI), the strengths of the effective absorbing layer—a reduction of the computational and memory cost coupled with a simplistic implementation—significantly outweighs the limitation of incomplete absorption of outgoing waves relative to the SPML. More importantly, we demonstrate that this limitation can easily be overcome through the use of two strategies in FWI, namely variable cell size and model extension thereby fully compensating for the imperfectness of the proposed absorbing boundary condition.

Plate boundary deformation at the latitude of the Salton Trough - northern Gulf of California (Invited)

characteristics suggest that the zone of strike-slip faults related to past plate boundary deformation extends eastward into SW Arizona and beneath the Sonoran coastal plain. 3) 'New' crust and mantle lithosphere at the plate boundary, in the Salton Trough and the non-oceanic part of the northern Gulf of California, varies in seismic velocity structure and dimensions, both within and across extensional segments. Details of within-segment variations imaged by SSIP (e.g., Ma et al., and Han et al., this meeting) are attributed to active fault patterns and small scale variations in hydrothermal activity and magmatism superposed on a more uniform sedimentation. Differences between the Imperial Valley rift segment and the north Gulf of California segments may be due to more involvement of low angle normal faults in the marine basins in the south (Martin et al., 2013, Tectonics), as well as differences in lower crustal or mantle lithospheric flow from the adjacent continental regions.

Signatures of chaos and non-integrability in two-dimensional gravity with dynamical boundary

Full Text Available We propose a model of two-dimensional dilaton gravity with a boundary. In the bulk our model coincides with the classically integrable CGHS model; the dynamical boundary cuts of the CGHS strong-coupling region. As a result, classical dynamics in our model reminds that in the spherically-symmetric gravity: wave packets of matter fields either reflect from the boundary or form black holes. We find large integrable sector of multisoliton solutions in this model. At the same time, we argue that the model is globally non-integrable because solutions at the verge of black hole formation display chaotic properties.

Numerical study of magnetohydrodynamics (MHD boundary layer slip flow of a Maxwell nanofluid over an exponentially stretching surface with convective boundary condition

P.BalaAnki Reddy

2017-12-01

Full Text Available This paper focuses on a theoretical analysis of a steady two-dimensional magnetohydrodynamic boundary layer flow of a Maxwell fluid over an exponentially stretching surface in the presence of velocity slip and convective boundary condition. This model is used for a nanofluid, which incorporates the effects of Brownian motion and thermophoresis. The resulting non-linear partial differential equations of the governing flow field are converted into a system of coupled non-linear ordinary differential equations by using suitable similarity transformations, and the resultant equations are then solved numerically by using Runge-Kutta fourth order method along with shooting technique. A parametric study is conducted to illustrate the behavior of the velocity, temperature and concentration. The influence of significant parameters on velocity, temperature, concentration, skin friction coefficient and Nusselt number has been studied and numerical results are presented graphically and in tabular form. The reported numerical results are compared with previously published works on various special cases and are found to be an in excellent agreement. It is found that momentum boundary layer thickness decreases with the increase of magnetic parameter. It can also be found that the thermal boundary layer thickness increases with Brownian motion and thermophoresis parameters.

Deletion of an X-inactivation boundary disrupts adjacent gene silencing.

Directory of Open Access Journals (Sweden)

Lindsay M Horvath

2013-11-01

Full Text Available In mammalian females, genes on one X are largely silenced by X-chromosome inactivation (XCI, although some "escape" XCI and are expressed from both Xs. Escapees can closely juxtapose X-inactivated genes and provide a tractable model for assessing boundary function at epigenetically regulated loci. To delimit sequences at an XCI boundary, we examined female mouse embryonic stem cells carrying X-linked BAC transgenes derived from an endogenous escape locus. Previously we determined that large BACs carrying escapee Kdm5c and flanking X-inactivated transcripts are properly regulated. Here we identify two lines with truncated BACs that partially and completely delete the distal Kdm5c XCI boundary. This boundary is not required for escape, since despite integrating into regions that are normally X inactivated, transgenic Kdm5c escapes XCI, as determined by RNA FISH and by structurally adopting an active conformation that facilitates long-range preferential association with other escapees. Yet, XCI regulation is disrupted in the transgene fully lacking the distal boundary; integration site genes up to 350 kb downstream of the transgene now inappropriately escape XCI. Altogether, these results reveal two genetically separable XCI regulatory activities at Kdm5c. XCI escape is driven by a dominant element(s retained in the shortest transgene that therefore lies within or upstream of the Kdm5c locus. Additionally, the distal XCI boundary normally plays an essential role in preventing nearby genes from escaping XCI.

References to texts of the Roman law were meant to give ‘authority’ to resolutions often based upon customary praxis. The norms elaborated by Middle Ages jurists are thus given a formal legal shape; yet, they are linked to a perception of the boundaries between communities that was affected by the displacements, the customs, the common needs of everyday life. On the other side the existence of actual neat demarcations was linked to the exertion of certain rights and privileges rather than to an exclusive and absolute political claim.

Consistent boundary conditions for open strings

We study boundary conditions for the bosonic, spinning (NSR) and Green-Schwarz open string, as well as for (1+1)-dimensional supergravity. We consider boundary conditions that arise from (1) extremizing the action, (2) BRST, rigid or local supersymmetry, or κ(Siegel)-symmetry of the action, (3) closure of the set of boundary conditions under the symmetry transformations, and (4) the boundary limits of bulk Euler-Lagrange equations that are 'conjugate' to other boundary conditions. We find corrections to Neumann boundary conditions in the presence of a bulk tachyon field. We discuss a boundary superspace formalism. We also find that path integral quantization of the open string requires an infinite tower of boundary conditions that can be interpreted as a smoothness condition on the doubled interval; we interpret this to mean that for a path-integral formulation of open strings with only Neuman boundary conditions, the description in terms of orientifolds is not just natural, but is actually fundamental

A General 2D Meshless Interpolating Boundary Node Method Based on the Parameter Space

Hongyin Yang

2017-01-01

Full Text Available The presented study proposed an improved interpolating boundary node method (IIBNM for 2D potential problems. The improved interpolating moving least-square (IIMLS method was applied to construct the shape functions, of which the delta function properties and boundary conditions were directly implemented. In addition, any weight function used in the moving least-square (MLS method was also applicable in the IIMLS method. Boundary cells were required in the computation of the boundary integrals, and additional discretization error was not avoided if traditional cells were used to approximate the geometry. The present study applied the parametric cells created in the parameter space to preserve the exact geometry, and the geometry was maintained due to the number of cells. Only the number of nodes on the boundary was required as additional information for boundary node construction. Most importantly, the IIMLS method can be applied in the parameter space to construct shape functions without the requirement of additional computations for the curve length.

2014-01-01

Full Text Available The magnetohydrodynamic (MHD boundary layer flow of a nanofluid past a stretching/shrinking sheet with velocity, thermal, and solutal slip boundary conditions is studied. Numerical solutions to the governing equations were obtained using a shooting method. The skin friction coefficient and the local Sherwood number increase as the stretching/shrinking parameter increases. However, the local Nusselt number decreases with increasing the stretching/shrinking parameter. The range of the stretching/shrinking parameter for which the solution exists increases as the velocity slip parameter and the magnetic parameter increase. For the shrinking sheet, the skin friction coefficient increases as the velocity slip parameter and the magnetic parameter increase. For the stretching sheet, it decreases when the velocity slip parameter and the magnetic parameter increase. The local Nusselt number diminishes as the thermal slip parameter increases while the local Sherwood number decreases with increasing the solutal slip parameter. The local Nusselt number is lower for higher values of Lewis number, Brownian motion parameter, and thermophoresis parameter.

2006-01-01

We revisit the exact solution of the two space-time dimensional quantum field theory of a free massless boson with a periodic boundary interaction and self-dual period. We analyze the model by using a mapping to free fermions with a boundary mass term originally suggested in Ref. [J. Polchinski, L. Thorlacius, Phys. Rev. D 50 (1994) 622]. We find that the entire SL (2, C) family of boundary states of a single boson are boundary sine-Gordon states and we derive a simple explicit expression for the boundary state in fermion variables and as a function of sine-Gordon coupling constants. We use this expression to compute the partition function. We observe that the solution of the model has a strong-weak coupling generalization of T-duality. We then examine a class of recently discovered conformal boundary states for compact bosons with radii which are rational numbers times the self-dual radius. These have simple expression in fermion variables. We postulate sine-Gordon-like field theories with discrete gauge symmetries for which they are the appropriate boundary states

Solution of moving boundary problems with implicit boundary condition

International Nuclear Information System (INIS)

Moyano, E.A.

1990-01-01

An algorithm that solves numerically a model for studying one dimensional moving boundary problems, with implicit boundary condition, is described. Landau's transformation is used, in order to work with a fixed number of nodes at each instant. Then, it is necessary to deal with a parabolic partial differential equation, whose diffusive and convective terms have variable coefficients. The partial differential equation is implicitly discretized, using Laasonen's scheme, always stable, instead of employing Crank-Nicholson sheme, as it has been done by Ferris and Hill. Fixed time and space steps (Δt, Δξ) are used, and the iteration is made with variable positions of the interface, i.e. varying δs until a boundary condition is satisfied. The model has the same features of the oxygen diffusion in absorbing tissue. It would be capable of estimating time variant radiation treatments of cancerous tumors. (Author) [es

Investigation of turbulence models with compressibility corrections for hypersonic boundary flows

Directory of Open Access Journals (Sweden)

Han Tang

2015-12-01

Full Text Available The applications of pressure work, pressure-dilatation, and dilatation-dissipation (Sarkar, Zeman, and Wilcox models to hypersonic boundary flows are investigated. The flat plate boundary layer flows of Mach number 5–11 and shock wave/boundary layer interactions of compression corners are simulated numerically. For the flat plate boundary layer flows, original turbulence models overestimate the heat flux with Mach number high up to 10, and compressibility corrections applied to turbulence models lead to a decrease in friction coefficients and heating rates. The pressure work and pressure-dilatation models yield the better results. Among the three dilatation-dissipation models, Sarkar and Wilcox corrections present larger deviations from the experiment measurement, while Zeman correction can achieve acceptable results. For hypersonic compression corner flows, due to the evident increase of turbulence Mach number in separation zone, compressibility corrections make the separation areas larger, thus cannot improve the accuracy of calculated results. It is unreasonable that compressibility corrections take effect in separation zone. Density-corrected model by Catris and Aupoix is suitable for shock wave/boundary layer interaction flows which can improve the simulation accuracy of the peak heating and have a little influence on separation zone.

Recently, we have extended research on this phenomenon by showing that undergraduates with no formal musical training and children as young as 3 years lengthen phrase boundaries during self...... uncertain than low-entropy contexts. Because phrase boundaries tend to afford high-entropy continuations, thus generating uncertain expectations in the listener, one possibility is that boundary perception is directly related to entropy.

Numerical simulation of boundary heat flow effects on directional solidification microstructure of a binary alloy

Directory of Open Access Journals (Sweden)

Xue Xiang

2010-08-01

Full Text Available The boundary heat flow has important significance for the microstructures of directional solidified binary alloy. Interface evolution of the directional solidified microstructure with different boundary heat flow was discussed. In this study, only one interface was allowed to have heat flow, and Neumann boundary conditions were imposed at the other three interfaces. From the calculated results, it was found that different boundary heat flows will result in different microstructures. When the boundary heat flow equals to 20 W·cm-2, the growth of longitudinal side branches is accelerated and the growth of transverse side branches is restrained, and meanwhile, there is dendritic remelting in the calculation domain. When the boundary heat flow equals to 40 W·cm-2, the growths of the transverse and longitudinal side branches compete with each other, and when the boundary heat flow equals to 100-200 W·cm-2, the growth of transverse side branches dominates absolutely. The temperature field of dendritic growth was analyzed and the relation between boundary heat flow and temperature field was also investigated.

Understanding and prediction of the stable atmospheric boundary layer is a challenging task. Many physical processes are relevant in the stable boundary layer, i.e. turbulence, radiation, land surface coupling, orographic turbulent and gravity wave drag, and land surface heterogeneity. The development of robust stable boundary layer parameterizations for use in NWP and climate models is hampered by the multiplicity of processes and their unknown interactions. As a result, these models suffer ...

Effect of boundary conditions on downstream vorticity from counter-rotating swirlers

Directory of Open Access Journals (Sweden)

Weiye Huo

2015-02-01

Full Text Available Particle image velocimetry (PIV is utilized to measure the non-reacting flow field in a reflow combustor with multiple and single swirlers. The velocity field, vortex structure and total vorticity levels are experimentally obtained using two different boundary conditions, representing a single confined swirler and multiple swirlers in an annular combustor. The influence of the boundary conditions on the flow field at several locations downstream of the swirlers is experimentally investigated, showing that the central vortex in the multi-swirler case is more concentrated than in the single-swirler case. The vorticity of the central vortex and average cross-sectional vorticity are relatively low at the swirler outlet in both cases. Both of these statistics gradually increase to the maximum values near 20 mm downstream of the swirler outlet, and subsequently decrease. It is also found that the central vortex in the multi-swirler case is consistently greater than the single-swirler case. These results demonstrate the critical influence of boundary conditions on flow characteristic of swirling flow, providing insight into the difference of the experiments on test-bed combustor and the full-scale annular combustors.

Work and personal life boundary management: boundary strength, work/personal life balance, and the segmentation-integration continuum.

Bulger, Carrie A; Matthews, Russell A; Hoffman, Mark E

2007-10-01

While researchers are increasingly interested in understanding the boundaries surrounding the work and personal life domains, few have tested the propositions set forth by theory. Boundary theory proposes that individuals manage the boundaries between work and personal life through processes of segmenting and/or integrating the domains. The authors investigated boundary management profiles of 332 workers in an investigation of the segmentation-integration continuum. Cluster analysis indicated consistent clusters of boundary management practices related to varying segmentation and integration of the work and personal life domains. But, the authors suggest that the segmentation-integration continuum may be more complicated. Results also indicated relationships between boundary management practices and work-personal life interference and work-personal life enhancement. Less flexible and more permeable boundaries were related to more interference, while more flexible and more permeable boundaries were related to more enhancement.

Pyramidal resistor networks for electrical impedance tomography with partial boundary measurements

International Nuclear Information System (INIS)

Borcea, L; Mamonov, A V; Druskin, V; Vasquez, F Guevara

2010-01-01

We introduce an inversion algorithm for electrical impedance tomography (EIT) with partial boundary measurements in two dimensions. It gives stable and fast reconstructions using sparse parameterizations of the unknown conductivity on optimal grids that are computed as part of the inversion. We follow the approach in Borcea et al (2008 Inverse Problems 24 035013) and Vasquez (2006 PhD thesis Rice University, Houston, TX, USA) that connects inverse discrete problems for resistor networks to continuum EIT problems, using optimal grids. The algorithm in Borcea et al (2008 Inverse Problems 24 035013) and Vasquez (2006 PhD Thesis Rice University, Houston, TX, USA) is based on circular resistor networks, and solves the EIT problem with full boundary measurements. It is extended in Borcea et al (2010 Inverse Problems 26 045010) to EIT with partial boundary measurements, using extremal quasi-conformal mappings that transform the problem to one with full boundary measurements. Here we introduce a different class of optimal grids, based on resistor networks with pyramidal topology, that is better suited for the partial measurements setup. We prove the unique solvability of the discrete inverse problem for these networks and develop an algorithm for finding them from the measurements of the Dirichlet to Neumann map. Then, we show how to use the networks to define the optimal grids and to approximate the unknown conductivity. We assess the performance of our approach with numerical simulations and compare the results with those in Borcea et al (2010)

New Boundary-Driven Twist States in Systems with Broken Spatial Inversion Symmetry

Hals, Kjetil M. D.; Everschor-Sitte, Karin

2017-09-01

A full description of a magnetic sample includes a correct treatment of the boundary conditions (BCs). This is in particular important in thin film systems, where even bulk properties might be modified by the properties of the boundary of the sample. We study generic ferromagnets with broken spatial inversion symmetry and derive the general micromagnetic BCs of a system with Dzyaloshinskii-Moriya interaction (DMI). We demonstrate that the BCs require the full tensorial structure of the third-rank DMI tensor and not just the antisymmetric part, which is usually taken into account. Specifically, we study systems with C∞ v symmetry and explore the consequences of the DMI. Interestingly, we find that the DMI already in the simplest case of a ferromagnetic thin film leads to a purely boundary-driven magnetic twist state at the edges of the sample. The twist state represents a new type of DMI-induced spin structure, which is completely independent of the internal DMI field. We estimate the size of the texture-induced magnetoresistance effect being in the range of that of domain walls.

Analytic Solution to Shell Boundary – Value Problems

Full Text Available Object of research is to find analytical solution to the shell boundary – value problems, i.e. to consider the solution for a class of problems concerning the mechanics of hoop closed shells strain.The objective of work is to create an analytical method to define a stress – strain state of shells under non-axisymmetric loading. Thus, a main goal is to derive the formulas – solutions of the linear ordinary differential equations with variable continuous coefficients.The partial derivative differential equations of mechanics of shells strain by Fourier's method of variables division are reduced to the system of the differential equations with ordinary derivatives. The paper presents the obtained formulas to define solutions of the uniform differential equations and received on their basis formulas to define a particular solution depending on a type of the right parts of the differential equations.The analytical algorithm of the solution of a boundary task uses an approach to transfer the boundary conditions to the randomly chosen point of an interval of changing independent variable through the solution of the canonical matrix ordinary differential equation with the subsequent solution of system of algebraic equations for compatibility of boundary conditions at this point. Efficiency of algorithm is based on the fact that the solution of the ordinary differential equations is defined as the values of Cauchy – Krylova functions, which meet initial arbitrary conditions.The results of researches presented in work are useful to experts in the field of calculus mathematics, dealing with solution of systems of linear ordinary differential equations and creation of effective analytical computing methods to solve shell boundary – value problems.

Analysis of turbulent boundary layers

Analysis of Turbulent Boundary Layers focuses on turbulent flows meeting the requirements for the boundary-layer or thin-shear-layer approximations. Its approach is devising relatively fundamental, and often subtle, empirical engineering correlations, which are then introduced into various forms of describing equations for final solution. After introducing the topic on turbulence, the book examines the conservation equations for compressible turbulent flows, boundary-layer equations, and general behavior of turbulent boundary layers. The latter chapters describe the CS method for calculati

Thermal Simulations, Open Boundary Conditions and Switches

Directory of Open Access Journals (Sweden)

Burnier Yannis

2018-01-01

Full Text Available SU(N gauge theories on compact spaces have a non-trivial vacuum structure characterized by a countable set of topological sectors and their topological charge. In lattice simulations, every topological sector needs to be explored a number of times which reflects its weight in the path integral. Current lattice simulations are impeded by the so-called freezing of the topological charge problem. As the continuum is approached, energy barriers between topological sectors become well defined and the simulations get trapped in a given sector. A possible way out was introduced by Lüscher and Schaefer using open boundary condition in the time extent. However, this solution cannot be used for thermal simulations, where the time direction is required to be periodic. In this proceedings, we present results obtained using open boundary conditions in space, at non-zero temperature. With these conditions, the topological charge is not quantized and the topological barriers are lifted. A downside of this method are the strong finite-size effects introduced by the boundary conditions. We also present some exploratory results which show how these conditions could be used on an algorithmic level to reshuffle the system and generate periodic configurations with non-zero topological charge.

Turbulent fluxes in stably stratified boundary layers

International Nuclear Information System (INIS)

L'vov, Victor S; Procaccia, Itamar; Rudenko, Oleksii

2008-01-01

We present here an extended version of an invited talk we gave at the international conference 'Turbulent Mixing and Beyond'. The dynamical and statistical description of stably stratified turbulent boundary layers with the important example of the stable atmospheric boundary layer in mind is addressed. Traditional approaches to this problem, based on the profiles of mean quantities, velocity second-order correlations and dimensional estimates of the turbulent thermal flux, run into a well-known difficulty, predicting the suppression of turbulence at a small critical value of the Richardson number, in contradiction to observations. Phenomenological attempts to overcome this problem suffer from various theoretical inconsistencies. Here, we present an approach taking into full account all the second-order statistics, which allows us to respect the conservation of total mechanical energy. The analysis culminates in an analytic solution of the profiles of all mean quantities and all second-order correlations, removing the unphysical predictions of previous theories. We propose that the approach taken here is sufficient to describe the lower parts of the atmospheric boundary layer, as long as the Richardson number does not exceed an order of unity. For much higher Richardson numbers, the physics may change qualitatively, requiring careful consideration of the potential Kelvin-Helmoholtz waves and their interaction with the vortical turbulence.

Hu, Jiancheng

2016-01-01

In this paper, a second-order nonlinear singular boundary value problem is presented, which is equivalent to the well-known Falkner-Skan equation. And the one-dimensional third-order boundary value problem on interval [Formula: see text] is equivalently transformed into a second-order boundary value problem on finite interval [Formula: see text]. The finite difference method is utilized to solve the singular boundary value problem, in which the amount of computational effort is significantly less than the other numerical methods. The numerical solutions obtained by the finite difference method are in agreement with those obtained by previous authors.

A new banding technique for nesting adult purple martins

Mery (1966) showed an almost equal sex ratio, males returned more frequently than females, over 50% of returns paired with other returns, an adult return rate of 20%, and no pair bonds maintained for more than one season. Her study lasted 13 years. Our study has shown that the return rate of locals to parent colonies is 4.1%, sex ratios are nearly equal (combination of banding and observation), return rate of locals to nearby colonies is 0.9,one pair maintained the pair bond for two years, SY females lay fewer eggs than ASY's, SY adults occasionally do not feed frequently enough to maintain the normal growth pattern of the young, SY adults often build poorly constructed nests with little or no mud, overall nest success is lower in SY adults, adults do indeed return to the same colony (19.6%) box and/or compartment, sexes are balanced in a stable colony, males or females are sometimes in excess in a new colony, SY adults are predominate in a new colony, the limiting factor in colony size is most likely the number of boxes and/or compartments available for nesting and,finally, adults and young do indeed use the boxes for roosting after nesting and fledging is complete (even boxes not their own). All of our results are tentative and subject to change after f rther study. Much additional study will be required before we can come up with conclusive answers to many of these questions about the Purple Martin.

Two-point functions and logarithmic boundary operators in boundary logarithmic conformal field theories

2004-01-01

Amongst conformal field theories, there exist logarithmic conformal field theories such as c p,1 models. We have investigated c p,q models with a boundary in search of logarithmic theories and have found logarithmic solutions of two-point functions in the context of the Coulomb gas picture. We have also found the relations between coefficients in the two-point functions and correlation functions of logarithmic boundary operators, and have confirmed the solutions in [hep-th/0003184]. Other two-point functions and boundary operators have also been studied in the free boson construction of boundary CFT with SU(2) k symmetry in regard to logarithmic theories. This paper is based on a part of D. Phil. Thesis [hep-th/0312160]. (author)

Oscillations of the Outer Boundary of the Outer Radiation Belt During Sawtooth Oscillations

Directory of Open Access Journals (Sweden)

Jae-Hun Kim

2006-09-01

Full Text Available We report three sawtooth oscillation events observed at geosynchronous orbit where we find quasi-periodic (every 2-3 hours sudden flux increases followed by slow flux decreases at the energy levels of ˜50-400 keV. For these three sawtooth events, we have examined variations of the outer boundary of the outer radiation belt. In order to determine L values of the outer boundary, we have used data of relativistic electron flux observed by the SAMPEX satellite. We find that the outer boundary of the outer radiation belt oscillates periodically being consistent with sawtooth oscillation phases. Specifically, the outer boundary of the outer radiation belt expands (namely, the boundary L value increases following the sawtooth particle flux enhancement of each tooth, and then contracts (namely, the boundary L value decreases while the sawtooth flux decreases gradually until the next flux enhancement. On the other hand, it is repeatedly seen that the asymmetry of the magnetic field intensity between dayside and nightside decreases (increases due to the dipolarization (the stretching on the nightside as the sawtooth flux increases (decreases. This implies that the periodic magnetic field variations during the sawtooth oscillations are likely responsible for the expansion-contraction oscillations of the outer boundary of the outer radiation belt.

Simulation of Thermal Flow Problems via a Hybrid Immersed Boundary-Lattice Boltzmann Method

Directory of Open Access Journals (Sweden)

J. Wu

2012-01-01

Full Text Available A hybrid immersed boundary-lattice Boltzmann method (IB-LBM is presented in this work to simulate the thermal flow problems. In current approach, the flow field is resolved by using our recently developed boundary condition-enforced IB-LBM (Wu and Shu, (2009. The nonslip boundary condition on the solid boundary is enforced in simulation. At the same time, to capture the temperature development, the conventional energy equation is resolved. To model the effect of immersed boundary on temperature field, the heat source term is introduced. Different from previous studies, the heat source term is set as unknown rather than predetermined. Inspired by the idea in (Wu and Shu, (2009, the unknown is calculated in such a way that the temperature at the boundary interpolated from the corrected temperature field accurately satisfies the thermal boundary condition. In addition, based on the resolved temperature correction, an efficient way to compute the local and average Nusselt numbers is also proposed in this work. As compared with traditional implementation, no approximation for temperature gradients is required. To validate the present method, the numerical simulations of forced convection are carried out. The obtained results show good agreement with data in the literature.

Inside Out: Organizations as Service Systems Equipped with Relational Boundaries

Directory of Open Access Journals (Sweden)

María Jimena Crespo Garrido

2017-04-01

Full Text Available Currently, literature on organizational boundaries is at the center of a heated debate, characterized by a shift from a transactional approach to a broader immaterial perspective centered on the concept of boundless organizations. However, the overestimation of the effects of contemporary dematerialization on business processes can lead to the progressive neglect of the existence of corporate borders. In light of this consideration, the present work aims at proposing a new type of criterion for defining organizational boundaries, halfway between the conception of the firm’s total openness and total closure. To this end, the authors envisage the use of a new interpretive logic defined as “relational”, resulting from the specification of the systemic view (and as the sum of the logic underlying the viable systems approach (VSA. This approach views the definition of boundaries. Therefore, in the large and intricate scenery of the studies dedicated to organizational boundaries, this work contributes to a better understanding of border selection as an interactive and changeable process capable of pushing organizations towards a greater awareness of their strategic dimension. This paper also offers some insights for future research, suggesting that both scholars and professionals investigate, firstly, new frontiers for the identification of organizational boundaries and, secondly, the possible positive repercussions that new organizational redesign modes could determine for a greater competitive success.

Complex Dynamics on the Routes to Chaos in a Discrete Predator-Prey System with Crowley-Martin Type Functional Response

2018-01-01

Full Text Available We present in this paper an investigation on a discrete predator-prey system with Crowley-Martin type functional response to know its complex dynamics on the routes to chaos which are induced by bifurcations. Via application of the center manifold theorem and bifurcation theorems, occurrence conditions for flip bifurcation and Neimark-Sacker bifurcation are determined, respectively. Numerical simulations are performed, on the one hand, verifying the theoretical results and, on the other hand, revealing new interesting dynamical behaviors of the discrete predator-prey system, including period-doubling cascades, period-2, period-3, period-4, period-5, period-6, period-7, period-8, period-9, period-11, period-13, period-15, period-16, period-20, period-22, period-24, period-30, and period-34 orbits, invariant cycles, chaotic attractors, sub-flip bifurcation, sub-(inverse Neimark-Sacker bifurcation, chaotic interior crisis, chaotic band, sudden disappearance of chaotic dynamics and abrupt emergence of chaos, and intermittent periodic behaviors. Moreover, three-dimensional bifurcation diagrams are utilized to study the transition between flip bifurcation and Neimark-Sacker bifurcation, and a critical case between the two bifurcations is found. This critical bifurcation case is a combination of flip bifurcation and Neimark-Sacker bifurcation, showing the nonlinear characteristics of both bifurcations.
