    Hartman's linearization theorem tells us that if matrix A has no zero real part and f(x) isbounded and satisfies Lipchitz condition with small Lipchitzian constant, then there exists a homeomorphismof Rn sending the solutions of nonlinear system x' = Ax + f(x) onto the solutions of linear system x' = Ax.In this paper, some components of the nonlinear item f(x) are permitted to be unbounded and we provethe result of global topological linearization without any special limitation and adding any condition. Thus,Hartman's linearization theorem is improved essentially.

    2014-05-07

    Tunneling times, including group delay and dwell time, are studied for massless Dirac electrons transmitting through a one-dimensional barrier in strain-engineered graphene. The Hartman effect, the independence of group delay on barrier length, is induced by the strain effect, and associated with the transmission gap and the evanescent mode. The influence of barrier height/length and strain modulus/direction on the group delay is also discussed, which provides the flexibility to control the group delay with applications in graphene-based devices. The relationship between group delay and dwell time is finally derived to clarify the nature of the Hartman effect.

  9. Tunable delay time and Hartman effect in graphene magnetic barriers

    2015-04-28

    Tunable group delay and Hartman effect have been investigated for massless Dirac electrons in graphene magnetic barriers. In the presence of magnetic field, dwell time is found to be equal to net group delay plus the group delay contributing from the lateral shifts. The group delay times are discussed in both cases of normal and oblique incidence, to clarify the nature of Hartman effect. In addition, the group delay in transmission can be modulated from subluminality to superluminality by adjusting the magnetic field, which may also lead to potential applications in graphene-based microelectronics.

    2005-01-01

    Adalbert Friedrich Markus (1753-1816) was one of the most eminent doctors of his time. His name was given not accidentally to one of the largest squares, a street and a bridge across the river Regnitz in Bamberg, the town where he worked more than 40 years. Markus was well-known among the population as an excellent doctor, he also was a personal doctor of Kurfürst bishop Franz Ludwig von Erthal. Markus was the first principal to found a hospital affordable to everyone, where medical personnel was taught and many professors worked. He was also founder and principal of the medico-surgical school, whose program of studies was equal to those of an university. On Markus' initiative a birthhouse was founded, as well as a sheltered housing complex for the elderly and a school, as well as a social system for poor citizens. In January 1803 Markus became the head of the health department of the principality of Frankonia. On his initiative a free smallpocks vaccination for all new born was carried out. Markus brought up an annual report of medical science and numerous magazines on therapy. In his scientifical articles in different magazines he wrote about diseases of respiratory tract, skin, liver, as well as typhus and feaver. In many of his published works he appears to be a philosopher supporting a naturalistic philosophy and disagreeing with its idealistic attitude at the same time. He was the head of a literature society called "Harmony", and he supported the construction of the first theatre where E. T. A Hoffmann worked who was a friend of Markus. A. F. Markus' death 1816 put his friends and supporters into a deep grief. According to the newspapers of that time, the whole town followed the funeral procession and all the churches rang their bells goodbye. The name of A. F. Markus has an important place among the extraordinary German physicians of the late 18th and early 19th century.

    @@ The Hartman effect inside the one-dimensional photonic crystals (1DPCS) composed of negative index materials (NIMS) is always and is reversed to the Hartman effect inside the 1DPCS composed of positive index materials (PIMs).By calculating the phases of Fourier components of a pulse accumulated inside the 1DPCs of NIMs and the evolution of the pulse inside the 1DPCs of NIMs, the origin of the negative phase time is explained.The evolution of the electromagnetic fields inside the 1DPCs of NIMs is time reversal with conjugate to that inside the 1DPCs of PIMs for real spectral pulses.

    2008-12-01

    The differential diagnosis of malingering in psychological evaluations for Posttraumatic Stress Disorder (PTSD) is complex and relies upon the integration of clinical knowledge and appropriate psychometric instruments. Over the years, there has been an increase in the use of validity measures, including Symptom Validity Tests (SVTs). In 2005, the National Academy of Neuropsychology published Symptom validity assessment: Practice issues and medical necessity, an official policy statement recognizing the importance of effort on test performance and recommending the utilization of specific SVTs to assess for response bias in neurocognitive and personality evaluations. As new SVTs become available, clinicians need a clear understanding of how to critique these tests and determine the strengths and limitations. This article demonstrates the fundamental principles of critiquing an SVT by applying a modified set of Hartman's [Hartman, D. E. (2002). The unexamined lie is a lie worth fibbing: Neuropsychological malingering and the Word Memory Test. Archives of Clinical Neuropsychology, 17, 709-714] criteria, originally developed for neuropsychological SVTs, to the Morel Emotional Numbing Test for Posttraumatic Stress Disorder (MENT).

    2011-01-01

    We study the continuous and discrete versions of the Markus-Yamabe Conjecture for polynomial vector fields in $ \\mathbb{R}^3 $ of the form $ X = \\lambda \\, I + H $, where $ \\lambda $ is a real number, I the identity map, and H a map with nilpotent Jacobian matrix $ JH $. We distinguish the cases when the rows of $ J H $ are linearly dependent over $ \\mathbb{R} $ and when they are linearly independent over $ \\mathbb{R} $. In the dependent continuous case, we give a polynomial family of counterexamples to the Markus-Yamabe conjecture which contains and generalizes that of Cima-Gasull-Ma\\~nosas. Furthermore, we construct a new class of polynomial vector fields in $\\mathbb{R}^3$ having the origin as a global attractor. We also find non--linearly triangularizable vector fields $ X $ for which the origin is a global attractor for both the continuous and the discrete dynamical systems generated by $ X $. In the independent continuous case, we present a family of vector fields that have orbits escaping to infinity.

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2017v70n1p135 For a better understanding of a given narrative it is essential to be aware of the one who perceives (the focalizer. His beliefs and comprehension determine which characters and circumstances are to be ignored or closely examined through his use of sight, hearing, feeling, taste or smell. Therefore, the issue concerning focalization is relevant to be taken into consideration when a literary work is analyzed. In the present article the work by the Australian author Markus Zusak, The Book Thief, is discussed under the assumptions from the narratological field, especially guided by Gérard Genette, Mieke Bal and Rimmon-Kenan. It is argued that focalization in The Book Thief is one of the main literary techniques which help creating the atmosphere and meaning of the text.

    We describe MarkUs, a web server for analysis and comparison of the structural and functional properties of proteins. In contrast to a ‘structure in/function out’ approach to protein function annotation, the server is designed to be highly interactive and to allow flexibility in the examination of possible functions, suggested either automatically by various similarity measures or specified by a user directly. This is combined with tools that allow a user to assess independently whether or not a suggested function is consistent with the bioinformatic and biophysical properties of a given query structure, further allowing the user to generate testable hypotheses. The server is available at http://wiki.c2b2.columbia.edu/honiglab_public/index.php/Software:Mark-Us. PMID:21672961

  7. Franz Kafka, Sigmund Freud and Markus Hajek. A connection in life and death.

    When Sigmund Freud was taken ill in 1923 with a malignant tumor of his right upper jaw he was initially treated by the famous Viennese rhino-laryngologist, Professor Markus Hajek. One year later, Franz Kafka, who was suffering from pulmonary tuberculosis which had spread to the larynx, was likewise placed under the care of this distinguished specialist. Neither of the encounters proved beneficial from the professional point of view and both well-known patients received remarkably poor attentions in keeping with the general autocratic attitude by clinical chiefs of the time in Vienna. Franz Kafka was terminally ill when he came to Hajek and no treatment was yet available for the disabling and painful laryngeal complication of his advanced tuberculosis. He died about a month after leaving Hajek's ward in Vienna. Sigmund Freud required repeated subsequent operations on his jaw and the insertion of a prothesis. Hajek had handed Freud over to Hans Pichler for further care and it was entirely due to the skill of this extremely competent and empathetic maxilliary surgeon that Freud lived for another 16 years, working to almost full capacity.

  9. _Also d'Susi wär e ganz e liebi Frau für de Markus!_ Zur Verdoppelung des indefiniten Artikels in der adverbiell erweiterten Nominalphrase im Schweizerdeutschen

    Directory of Open Access Journals (Sweden)

    Steiner, Janine

    2005-01-01

    Full Text Available Three possible constructions of adverbially complemented noun phrases are attested in Swiss German. In (1, the indefinite article is doubled, whereas in (2 and (3 the article appears only once; it precedes or follows the adverb, respectively:(1 Also d' Susi wär e ganz e liebi Frau für de Markus! So the Susi would_be Art really Art lovely wife for the Markus! 'Susi would be a really lovely wife for Markus!' (2 Also d' Susi wär ganz e liebi Frau für de Markus! So the Susi would_be really Art lovely wife for the Markus! 'Susi would be a really lovely wife for Markus!' (3 Also d' Susi wär e ganz liebi Frau für de Markus! So the Susi would_be Art really lovely wife for the Markus! 'Susi would be a really lovely wife for Markus!' Doubling of the indefinite article is quite often mentioned in dialectological literature. Unfortunately there is nothing to be found about regional differences, frequency or possible contexts for a doubling in most standard works of Swiss German dialectology. The present paper now fills in some of these gaps in research on the adverbially complemented noun phrase in Swiss German:In a quantitative analysis will be shown that the construction with the article between adverb and adjective (2 is the one given the highest acceptance and preference rates by the informants. Furthermore the paper also shows that the doubling-construction (1 is more prominent in some Swiss German speaking-areas than in others. An apparent time analysis reveals ongoing language change and, last but not least, it shows that sociolinguistic parameters have an impact on the adverbially complemented noun phrase as well.

    The purpose of this study is to analyze the repeatability and agreement of corneal power using a new Hartman type topographer in comparison to Scheimpflug+Placido and autorefractor devices. In this cross sectional, observational study performed at the cornea services of a specialty hospital, 100 normal eyes (100 consecutive candidates) without any previous ocular surgery or morbidity except refractive error were evaluated. All candidates underwent three measurements each on a Full gradient, Hartman type topographer (FG) (iDesign, AMO), Scheimpflug+Placido topographer (SP) (Sirius, CSO) and rotating prism auto-keratorefractor (AR) (KR1, Nidek). The parameters assessed were flat keratometry (K1), steep keratometry (K2), steep axis (K2 axis), mean K, J 0 and J 45. Intra-device repeatability and inter-device agreement were evaluated. On repeatability analysis, the intra-device means were not significantly different (ANOVA, p > 0.05). Intraclass correlations (ICC) were >0.98 except for J 0 and J 45. In terms of intra-measurement standard deviation (Sw), the SP and FG groups fared better than AR group (p 0.05, R (2) 0.05). ICC ranged from 0.92 to 0.99 (p < 0.001). Regression fits on Bland-Altman plots suggested no clinically significant effect of average values over difference in means. The repeatability of Hartman type topographer in normal eyes is comparable to SP combination device and better than AR. The agreement between the three devices is good. However, we recommend against interchanging these devices between follow-ups or pooling their data.

  13. SU-E-T-448: On the Perturbation Factor P-cav of the Markus Parallel Plate Ion Chambers in Clinical Electron Beams, Monte Carlo Based Reintegration of An Historical Experiment

    Energy Technology Data Exchange (ETDEWEB)

    Voigts-Rhetz, P von; Zink, K [Technische Hochschule Mittelhessen - University of Applied Sciences, Giessen, Hessen (Germany)

    2014-06-01

    Purpose: All present dosimetry protocols recommend well-guarded parallel-plate ion chambers for electron dosimetry. For the guard-less Markus chamber an energy dependent fluence perturbation correction pcav is given. This perturbation correction was experimentally determined by van der Plaetsen by comparison of the read-out of a Markus and a NACP chamber, which was assumed to be “perturbation-free”. Aim of the present study is a Monte Carlo based reiteration of this experiment. Methods: Detailed models of four parallel-plate chambers (Roos, Markus, NACP and Advanced Markus) were designed using the Monte Carlo code EGSnrc and placed in a water phantom. For all chambers the dose to the active volume filled with low density water was calculated for 13 clinical electron spectra (E{sub 0}=6-21 MeV) at the depth of maximum and at the reference depth under reference conditions. In all cases the chamber's reference point was positioned at the depth of measurement. Moreover, the dose to water DW was calculated in a small water voxel positioned at the same depth. Results: The calculated dose ratio D{sub NACP}/D{sub Markus}, which according to van der Plaetsen reflects the fluence perturbation correction of the Markus chamber, deviates less from unity than the values given by van der Plaetsen's but exhibits a similar energy dependence. The same holds for the dose ratios of the other well guarded chambers. But, in comparison to water, the Markus chamber reveals the smallest overall perturbation correction which is nearly energy independent at both investigated depths. Conclusion: The simulations principally confirm the energy dependence of the dose ratio D{sub NACP}/D{sub Markus} as published by van der Plaetsen. But, as shown by our simulations of the ratio D{sub W}/D{sub Markus}, the conclusion drawn in all dosimetry protocols is questionable: in contrast to all well-guarded chambers the guard-less Markus chamber reveals the smallest overall perturbation

    Full Text Available The aim of the study was to investigate surface and buildup region doses for 6 MV and 15 MV photon beams using a Markus parallel-plate ionization chamber, GafChromic EBT3 film, and MOSFET detector for different field sizes and beam angles. The measurements were made in a water equivalent solid phantom at the surface and in the buildup region of the 6 MV and 15 MV photon beams at 100 cm source-detector distance for 5 × 5, 10 × 10, and 20 × 20 cm2 field sizes and 0°, 30°, 60°, and 80° beam angles. The surface doses using 6 MV photon beams for 10 × 10 cm2 field size were found to be 20.3%, 18.8%, and 25.5% for Markus chamber, EBT3 film, and MOSFET detector, respectively. The surface doses using 15 MV photon beams for 10 × 10 cm2 field size were found to be 14.9%, 13.4%, and 16.4% for Markus chamber, EBT3 film, and MOSFET detector, respectively. The surface dose increased with field size for all dosimeters. As the angle of the incident radiation beam became more oblique, the surface dose increased. The effective measurement depths of dosimeters vary; thus, the results of the measurements could be different. This issue can lead to mistakes at surface and buildup dosimetry and must be taken into account.

    This paper proposes the exact solution for unsteady flow of a viscous incompressible electrically conducting fluid past a impulsively started infinite horizontal surface which is rotating with an angular velocity embedded in a saturated porous medium under the influence of strong magnetic field with hall effect. Our study focuses on the change of direction of the external magnetic field on the flow system which leads to change in the flow behavior and skin frictional forces at the boundary. Systems of flow equations are solved using Laplace transform technique. The impacts of control parameters Hartman number, rotation of the system, hall effect, inclination of the magnetic field, and Darcy number on primary and secondary velocities are shown graphically, skin friction at horizontal boundary in tabular form. For validating our results, in the absence of permeability of the porous medium and inclination of the magnetic field the results are in good agreement with the published results.

    The aim of the study was to investigate surface and buildup region doses for 6 MV photon beams using a Markus parallel-plate ionization chamber, GafChromic EBT3 film and MOSFET detector for different field sizes and beam angles. The measurements were made in a water equivalent solid phantom at the surface and in the buildup region of the 6 MV photon beams at 100 cm source-detector distance (SDD) for 5x5, 10x10 and 20x20 cm2 field sizes and 0, 30, 60, 80 and 90 beam angles. The surface doses for 10x10 cm2 field size were found to be 20.33%, 18.80% and 25.48% for Markus chamber, EBT3 film and MOSFET detector, respectively. The surface dose increased with field size for all dosimeters. As the angle of the incident radiation beam became more oblique, the surface dose increased. The effective measurement depths of dosimeters vary, thus the results of the measurements could be different. This issue can lead to mistakes at surface and buildup dosimetry, and must be taken into account.

    Full Text Available Anhand von qualitativen und quantitativen Daten wird in dieser soziologischen Studie die Bedeutung von Religiosität, Identität und Gender in muslimischen Frauenvereinen in Deutschland untersucht. Markus Gamper verknüpft die Ergebnisse mit den kulturtheoretischen Ansätzen von Stuart Hall und Homi K. Bhabha und vertritt die These, dass ein islamischer Feminismus in Deutschland existiere. Er stellt fest, dass es den in den Vereinen organisierten Frauen gelinge, Gegendiskurse zu der deutschen Mehrheitsgesellschaft sowie zu den androzentrisch geprägten muslimischen Gemeinschaften zu entwickeln und somit Widerstand gegen Diskriminierung zu leisten. Der Autor begegnet in den von ihm untersuchten Vereinen – statt ‚unterdrückten Muslima‘, wie sie von den Medien inszeniert werden – hochgebildeten Frauen, die selbstbewusst und unabhängig ein religiöses Leben führen.Using qualitative and quantitative data, this sociological study analyzes the meaning of religiosity, identity, and gender in Muslim women’s societies in Germany. Markus Gamper connects the findings to approaches from the field of cultural theory by Stuart Hall and Homi K. Bhabha. Furthermore, he advocates the proposition that Islamic feminism exists in Germany. He states that the women who are organized in these societies succeed in developing counter discourses to German mainstream society as well as to the androcentrically coined Muslim communities, thus, making a stand against discrimination. In the analyzed societies, the author encounters – instead of “suppressed Muslim women” as they are presented by the media – highly educated women, who, confidently and independently, lead a religious life.

    在《语言与生产:范式批判》一书中,马尔库什认为在诠释主体间性时,德国古典唯心主义发展出了一种超个人的主体理论。马克思批判了这种理论,并以生产范式重新诠释了主体间性概念,他把主体间性设定为一种外部的社会客观性。马克思以生产范式诠释主体间性的新颖之处就在于它首次使人类社会历史的客观性得到说明,并且为人类掌控自己的历史进程提供了契机。%In the book of Language and Production:A Critique of the Paradigms,Markus argues that the German classical idealism develops the theories of super-individual subject when understands inter-subjectivity. While Marx,who critiques those theories,interprets the inter-subjectivity by production paradigm and he posits it as ex-ternal social objectivity. The novelty of Marxˊs way is that the new interpretation first illustrates the objectivity of the historical development of human society and provides a moment for human beings to control their historical process.

    Röntgen's description of his discovery of x rays was convincing and comprehensive. The response of the scientific community and public was immediate and intense. In contrast, the discovery of radioactivity was a muddled affair that excited little interest. While it would prove far more revolutionary than that of x rays, the discovery of radioactivity began, in the words of Alfred Romer, as something of a dead horse. There it lay, too big to ignore, but what did you do with it? Even the discoverer, Henri Becquerel, left it to decay and went on to pursue other interests. For various reasons, others chose to investigate: Marie and Pierre Curie in France, William Crookes in England, and Ernest Rutherford in Canada. But it was Frederick Soddy, a young chemist with a fascination for alchemy, who, together with Rutherford, revealed the true nature of radioactivity: transmutation.

    The formalism to derive the absorbed dose to water from ionization chamber measurements in a phantom includes several wall correction factors depending on shape, size and composition of the chamber. Wall correction factors have been measured for a number of NACP and PTW/Markers Chambers. Significant deviations from calculated values occur due to uncertainties in the contribution to the total ionization from the different materials of these inhomogeneous ionization chambers. The discrepancies illustrate the need for the development of a homogeneous plane-parallel chamber. In addition, detailed Monte Carlo calculations, taking the different wall materials into account, are required to quantitatively predict the response of heterogeneous plane-parallel chambers in photon beams.

    The HATNet network consists of six identical fully automated instruments, with four at Fred Lawrence Whipple Observatory (FLWO) in AZ, and two on the roof of the Submillimeter Array Hangar Building at Mauna Kea Observatory (MKO) in HI. The light-gathering elements of each instrument include an 11cm diameter telephoto lens, a Sloan r filter, and a 4K*4K front-side-illuminated CCD camera. Observations made in 2007 and early 2008 were carried out using a Cousins R filter. The instruments have a field of view of 10.6°*10.6° and a pixel scale of 9"/pixel at the center of an image. Additional time-series photometric measurements were obtained for all four of the systems using Keplercam on the FLWO 1.2m telescope. For HAT-P-50 we also obtained follow-up photometry with the CCD imager on the Byrne Observatory at Sedgwick (BOS) 0.8m telescope, located at Sedgwick Reserve in Santa Ynez Valley, CA, and operated by the Las Cumbres Observatory Global Telescope institute (LCOGT).

  10. Development of whole sediment bioassay using the marine/estuarine polychaetes Polydora cornuta Bosc 1802 and Boccardia proboscidea Hartman 1940

    The growing need by Environment Canada for a battery of marine toxicity tests has prompted the development of chronic, sublethal, sediment bioassay tests using marine or estuarine annelids (polychaetes). Initially several species of polychaetes found in the Atlantic, Pacific and Arctic waters were assessed and a few of these were selected for testing survival and sensitivity under laboratory conditions and sensitivity to reference toxicants using field collected specimens. From these experiments, the authors identified several promising species and attempts were made to culture them. To date they have been successful in culturing one species from the Atlantic coast--Polydora cornuta and one species from the Pacific Coast--Boccardia proboscidea. They have been able to generate sufficient numbers of same-age larvae, raise them under controlled conditions to juveniles/young adults, and, subject them to a variety of Non-Contaminant Effects Trials (NCETs) and Contaminant Effects Trials (CETs). In the NCETs the authors determined the effect of food type and food ration, temperature, salinity, grain size, length of test condition. They found them to be moderately robust in terms of variable environmental parameters. In the CETs they found this species to be sensitive to sediments considered by Environment Canada to be toxic. They also determined the animal`s sensitivity to a reference toxicant CdCl{sub 2} (96 hr LC50).

    Full Text Available This article investigated whether Mark 5:25–34 proposes a radical discontinuity with the Jewish purity codes and subsequently, holds drastic liberating implications for women as far as access to the temple is concerned and more existentially speaking, access to Yahweh. It determined whether Leviticus speaks about women in such an androcentric and exclusive manner and whether Jewish culture is indeed so discriminating. This article argued that Mark 5:25–34 does indeed radically turn the Jewish purity codes upside down and that the Jesus movement proclaims a drastic liberation for women from social marginalisation. However, the original meaning of the text in Leviticus should not be viewed so negatively. The dreadful consequences of the exile and the destruction of the temple lead to the idea amongst the orthodox rabbi’s that the purity codes should be maintained in a very strict way. These codes were thought to ensure that the holiness of Yahweh would manifest in the social sphere, the people of Yahweh would be blessed and a catastrophe of these immense proportions would be avoided in future. Unfortunately, this lead to the degeneration of the cult, that became exclusive as many people were deprived from the presence of Yahweh. The author of the Gospel according to Mark is reacting to this and clearly voices his criticism against this marginalisation.

    In a recent report titled "Indications of anomalous heat energy production in a reactor device containing hydrogen loaded nickel powder" [arXiv:1305.3913], G. Levi and co-workers put forth several claims concerning the operations and performance of the so-called E-Cat of Andrea Rossi. We note first of all that the circumstances and people involved in the test make if far from being an independent one. We examine the claims put forth by the authors and note that in many cases they are not supported by the facts given in the report. The authors seem to jump to conclusions fitting pre-conceived ideas where alternative explanations are possible. In general we find that much attention is drawn to trivialities while important pieces of information and investigation are lacking and seem not to have been conducted or considered. These are characteristics more typically found in pseudo-scientific texts and have no place in a technical/scientific report on this level. We also note that the proposed claims would require...

  11. Radiative Peristaltic Flow of Jeffrey Nanofluid with Slip Conditions and Joule Heating.

    Directory of Open Access Journals (Sweden)

    Tasawar Hayat

    Full Text Available Mixed convection peristaltic flow of Jeffrey nanofluid in a channel with compliant walls is addressed here. The present investigation includes the viscous dissipation, thermal radiation and Joule heating. Whole analysis is performed for velocity, thermal and concentration slip conditions. Related problems through long wavelength and low Reynolds number are examined for stream function, temperature and concentration. Impacts of thermal radiation, Hartman number, Brownian motion parameter, thermophoresis, Joule heating and slip parameters are explored in detail. Clearly temperature is a decreasing function of Hartman number and radiation parameter.

  12. Factor analysis of the Career Decision Scale on South African high school students.

    Science.gov (United States)

    Watson, M B; Foxcroft, C D; Stead, G B

    1991-12-01

    A factor analytic study of the Career Decision Scale-High School version of Hartman and Hartman on 312 white South African adolescents from Grades 11 and 12 was undertaken. A simple two-factor structure emerged which accounted for 47.36% of the total variance in the scores. These results support the use of the version as a differential measure of career indecision and indicate that the number and structure of factors can change across populations. The implications of these results for research in South Africa are considered.

Both have rejected what Adams and Markus (2004) refer to as the "entity" conception of culture--the view that culture is coherent, stable, and located in the heads of collectivities' members--in favor of more supple and dynamic constructs. Culture, in…

  8. Effect of electromagnetic force on turbulent flow of molten metal in aluminum electrolysis cells

    Institute of Scientific and Technical Information of China (English)

    周萍; 梅炽; 周乃君; 姜昌伟

    2004-01-01

    The standard k-ε model was adopted to simulate the flow field of molten metal in three aluminum electrolysis cells with different anode risers. The Hartman number, Reynolds number and the turbulent Reynolds number of molten metal were calculated quantitatively. The turbulent Reynolds number is in the order of 103 , and Reynolds number is in the order of 104 if taking the depth of molten metal as the characteristic length. The results show that the molten metal flow is the turbulence of high Reynolds number, the turbulent Reynolds number is more appropriate than Reynolds number to be used to describe the turbulent characteristic of molten metal, and Hartman number displays very well that electromagnetic force inhibits turbulent motion of molten metal.

  9. Linearization via the Lie Derivative

    Directory of Open Access Journals (Sweden)

    Carmen Chicone

    2000-11-01

    Full Text Available The standard proof of the Grobman-Hartman linearization theorem for a flow at a hyperbolic rest point proceeds by first establishing the analogous result for hyperbolic fixed points of local diffeomorphisms. In this exposition we present a simple direct proof that avoids the discrete case altogether. We give new proofs for Hartman's smoothness results: A ${cal C}^2$ flow is ${cal C}^1$ linearizable at a hyperbolic sink, and a ${cal C}^2$ flow in the plane is ${cal C}^1$ linearizable at a hyperbolic rest point. Also, we formulate and prove some new results on smooth linearization for special classes of quasi-linear vector fields where either the nonlinear part is restricted or additional conditions on the spectrum of the linear part (not related to resonance conditions are imposed.

    This paper is devoted to the magnetohydrodynamic (MHD) peristaltic transport of nanofluid in a channel with wall properties. Flow analysis is addressed in the presence of viscous dissipation, partial slip and Joule heating effects. Mathematical modelling also includes the salient features of Brownian motion and thermophoresis. Both analytic and numerical solutions are provided. Comparison between the solutions is shown in a very good agreement. Attention is focused to the Brownian motion parameter, thermophoresis parameter, Hartman number, Eckert number and Prandtl number. Influences of various parameters on skin friction coefficient, Nusselt and Sherwood numbers are also investigated. It is found that both the temperature and nanoparticles concentration are increasing functions of Brownian motion and thermophoresis parameters. - Highlights: • Temperature rises when Brownian motion and thermophoresis effects intensify. • Temperature profile increases when thermal slip parameter increases. • Concentration field is a decreasing function of concentration slip parameter. • Temperature decreases whereas concentration increases for Hartman number.

Heat generation/absorption and convective surface condition effects are considered. Novel features of Brownian motion and thermophoresis are present. A non-uniform applied magnetic field is employed. Boundary layer and small magnetic Reynolds number assumptions are employed in the formulation. A newly developed condition with zero nanoparticles mass flux is imposed. The resulting nonlinear systems are solved. Convergence domains are explicitly identified. Graphs are analyzed for the outcome of sundry variables. Further local Nusselt number is computed and discussed. It is observed that the effects of Hartman number on the temperature and concentration distributions are qualitatively similar. Both temperature and concentration distributions are enhanced for larger Hartman number.

    2012-01-01

    After defining non-Gaussian L\\'evy processes for two-sided time, stochastic differential equations with such L\\'evy processes are considered. Solution paths for these stochastic differential equations have countable jump discontinuities in time. Topological equivalence (or conjugacy) for such an It\\^o stochastic differential equation and its transformed random differential equation is established. Consequently, a stochastic Hartman-Grobman theorem is proved for the linearization of the It\\^o ...

    2008-01-01

    Full Text Available Abstract We establish some exponential inequalities for positively associated random variables without the boundedness assumption. These inequalities improve the corresponding results obtained by Oliveira (2005. By one of the inequalities, we obtain the convergence rate for the case of geometrically decreasing covariances, which closes to the optimal achievable convergence rate for independent random variables under the Hartman-Wintner law of the iterated logarithm and improves the convergence rate derived by Oliveira (2005 for the above case.

    1997-01-01

    A phenomenological model for a measurement of barrier traversal times for particles is proposed. Two idealized detectors for passage and arrival provide entrance and exit times for the barrier traversal. The averaged traversal time is computed over the ensemble of particles detected twice, before and after the barrier. The Hartman effect can still be found when passage detectors that conserve the momentum distribution of the incident packet are used.

    An approximate solution to the problem of steady laminar flow of a viscous incompressible electrically con ducting fluid over a stretching sheet is presented. The approach is based on the idea of stretching the variables of the flow problem and then using least squares method to minimize the residual of a differential equation. The effects of the magnetic field on the flow characteristics are demonstrated through numerical computations with di f ferent values of the Hartman monber.

    2014-06-13

    We demonstrate the counterintuitive dispersion effect that the peaks (dips) in the gain spectrum correspond to abnormal (normal) dispersion, contrary to the usual Kramers-Kronig point of view. This effect may also lead to two unique features: a broadband abnormal dispersion region and an observable Hartman effect. These results are explained in terms of interference and boundary effects. Finally, two experiments are proposed for the potential experimental verification.

  7. Natural convection in square cavity filled with ferrofluid saturated porous medium in the presence of uniform magnetic field

    Science.gov (United States)

    Javed, Tariq; Mehmood, Z.; Abbas, Z.

    2017-02-01

    This article contains numerical results for free convection through square enclosure enclosing ferrofluid saturated porous medium when uniform magnetic field is applied upon the flow along x-axis. Heat is provided through bottom wall and a square blockage placed near left or right bottom corner of enclosure as a heat source. Left and right vertical boundaries of the cavity are considered insulated while upper wall is taken cold. The problem is modelled in terms of system of nonlinear partial differential equations. Finite element method has been adopted to compute numerical simulations of mathematical problem for wide range of pertinent flow parameters including Rayleigh number, Hartman number, Darcy number and Prandtl number. Analysis of results reveals that the strength of streamline circulation is an increasing function of Darcy and Prandtl number where convection heat transfer is dominant for large values of these parameters whereas increase in Hartman number has opposite effects on isotherms and streamline circulations. Thermal conductivity and hence local heat transfer rate of fluid gets increased when ferroparticles are introduced in the fluid. Average Nusselt number increases with increase in Darcy and Rayleigh numbers while it is decreases when Hartman number is increased.

    Full Text Available Opheliid polychaetes collected by the United States Antarctic Research Program and additional material from South America were made available for study through the Smithsonian Institution, Washington, D.C., USA. The Opheliidae from Antarctic seas were treated by Hartman (1966, 1967, 1978, who summarized earlier work and also described several new species. Of the five genera she recorded, two (Travisia and Kesun have since been synonymized and one, Ammotrypane, has been referred to Ophelina; Hartman’s records therefore encompass four genera, three of which are represented in the present collections. No representatives of Euzonus (Thoracophelia were found. The following species were recorded from Antarctica in the present study: Ophelia algida n. sp., Ophelina breviata (Ehlers, 1913, Ophelina cf. cylindricaudata (sensu Hartmann-Schröder and Rosenfeldt, 1989, Ophelina nematoides (Ehlers, 1913, Ophelina scaphigera (Ehlers, 1900, Ophelina cf. setigera (Hartman, 1978, Ophelina syringopyge (Ehlers, 1901, Travisia antarctica Hartman, 1967 (emended 1978, Travisia kerguelensis McIntosh, 1885, Travisia kerguelensis gravieri Monro, 1930, Travisia palmeri n. sp. and Travisia tincta n. sp. The new species of Ophelia is distinguished by having branchiae starting on chaetiger 2 (rather than on or after chaetiger 8 as in most species of this genus. Travisia palmeri has 22 chaetigers and is distinguished by long branchiae. Travisia kerguelensis gravieri is raised to full species status and renamed T. monroi. Travisia tincta n. sp., distinguished by a distinctive Methyl Green staining pattern and long branchiae, is described from off Peru.

  9. On Algebraic Approach in Quadratic Systems

    Directory of Open Access Journals (Sweden)

    Matej Mencinger

    2011-01-01

    Full Text Available When considering friction or resistance, many physical processes are mathematically simulated by quadratic systems of ODEs or discrete quadratic dynamical systems. Probably the most important problem when such systems are applied in engineering is the stability of critical points and (nonchaotic dynamics. In this paper we consider homogeneous quadratic systems via the so-called Markus approach. We use the one-to-one correspondence between homogeneous quadratic dynamical systems and algebra which was originally introduced by Markus in (1960. We resume some connections between the dynamics of the quadratic systems and (algebraic properties of the corresponding algebras. We consider some general connections and the influence of power-associativity in the corresponding quadratic system.

  11. Sex typing and the social perception of gender stereotypic and nonstereotypic behavior: the uniqueness of feminine males.

    Science.gov (United States)

    Lobel, T E

    1994-02-01

    The social perception of masculine, feminine, androgynous and undifferentiated males was examined. Preadolescent boys (n = 251) were shown a video film portraying a male target playing either a masculine game with boys, a feminine game with girls, a neutral game with boys, or a neutral game with girls and were required to make a variety of inferences about him. All 4 groups made similar cognitive stereotypic inferences that varied in accordance with the gender stereotypic nature of the target's behavior. However, for the affective judgments (e.g., liking the target and wanting to engage in activities with him), the feminine males showed a pattern of inferences that was not only different from other sex role orientations, but often the reverse. The implications of these results for S. L. Bem's gender schema theory (1981) and H. Markus's self schema theory (H. Markus, M. Crane, S. L. Bernstein, & M. Siladi, 1982) are discussed.

    1997-01-01

    The performance of two different alanine-ESR systems (1 mm ISS pellets and NRI films) in therapy proton beams was checked against reference dosimetry provided by a Markus parallel plate ionization chamber. Irradiations were performed at the OPTIS facility of the PSI with a 62 MeV proton beam. The energy dependence of the response was derived from the analysis of film stacks irradiated with pristine beams. In fact, 250 {mu}m films allowed for a high resolution sampling of the proton slowing down mechanisms. Moreover pellets were irradiated in unmodulated and modulated beams. Alanine dose distributions were always in good agreement with the PSI Markus chamber results. Simple density scaling allowed for the conversion of the results to the dose distributions in water, consistently with the good tissue equivalence properties of these detectors. (Author).

  7. Experimental determination of pCo perturbation factors for plane-parallel chambers.

    2007-12-07

    For plane-parallel chambers used in electron dosimetry, modern dosimetry protocols recommend a cross-calibration against a calibrated cylindrical chamber. The rationale for this is the unacceptably large (up to 3-4%) chamber-to-chamber variations of the perturbation factors (pwall)Co, which have been reported for plane-parallel chambers of a given type. In some recent publications, it was shown that this is no longer the case for modern plane-parallel chambers. The aims of the present study are to obtain reliable information about the variation of the perturbation factors for modern types of plane-parallel chambers, and-if this variation is found to be acceptably small-to determine type-specific mean values for these perturbation factors which can be used for absorbed dose measurements in electron beams using plane-parallel chambers. In an extensive multi-center study, the individual perturbation factors pCo (which are usually assumed to be equal to (pwall)Co) for a total of 35 plane-parallel chambers of the Roos type, 15 chambers of the Markus type and 12 chambers of the Advanced Markus type were determined. From a total of 188 cross-calibration measurements, variations of the pCo values for different chambers of the same type of at most 1.0%, 0.9% and 0.6% were found for the chambers of the Roos, Markus and Advanced Markus types, respectively. The mean pCo values obtained from all measurements are [Formula: see text] and [Formula: see text]; the relative experimental standard deviation of the individual pCo values is less than 0.24% for all chamber types; the relative standard uncertainty of the mean pCo values is 1.1%.

    Two new, large gas-giant exoplanets have been discovered orbiting close to their host stars. A recent study examining these planets and others like them may help us to better understand what happens to close-in hot Jupiters as their host stars reach the end of their main-sequence lives.OversizedGiantsUnbinned transit light curves for HAT-P-65b. [Adapted from Hartman et al. 2016]The discovery of HAT-P-65b and HAT-P-66b, two new transiting hot Jupiters, is intriguing. These planets have periods of just under 3 days and masses of roughly 0.5 and 0.8 times that of Jupiter, but their sizes are whats really interesting: they have inflated radii of 1.89 and 1.59 times that of Jupiter.These two planets, discovered using the Hungarian-made Automated Telescope Network (HATNet) in Arizona and Hawaii, mark the latest in an ever-growing sample of gas-giant exoplanets with radii larger than expected based on theoretical planetary structure models.What causes this discrepancy? Did the planets just fail to contract to the expected size when they were initially formed, or were they reinflated later in their lifetimes? If the latter, how? These are questions that scientists are only now starting to be able to address using statistics of the sample of close-in, transiting planets.Unbinned transit light curves for HAT-P-66b. [Hartman et al. 2016]Exploring Other PlanetsLed by Joel Hartman (Princeton University), the team that discovered HAT-P-65b and HAT-P-66b has examined these planets observed parameters and those of dozens of other known close-in, transiting exoplanets discovered with a variety of transiting exoplanet missions: HAT, WASP, Kepler, TrES, and KELT. Hartman and collaborators used this sample to draw conclusions about what causes some of these planets to have such large radii.The team found that there is a statistically significant correlation between the radii of close-in giant planets and the fractional ages of their host stars (i.e., the stars age divided by its full

Their carriers bring us this news of shards. Their message: behold this paltriness; this is all your history” (Armah 1973:2. It is this seeming paltriness, this history of meaningless fractions that Anne C. Bailey and Saidiya Hartman explore in their latest works, identifying and mending shards of memory and written and oral fragments into recognizable and meaningful forms. As with Armah in Two Thousand Seasons, for Bailey and Hartman, “the linking of those gone, ourselves here, those coming ... it is that remembrance that calls us” (Armah 1973:xiii. Both of them, haunted by remembrance and driven by a personal quest for reconciliation with the past and a scholarly desire for the truth, are unwilling to accept the past as passed, or to settle for the scattered silence that so often substitutes for the history of Africans and those of the diaspora.

    Objective of the present study is to determine the characteristics of magnetohydrodynamic flow by a rotating disk having variable thickness. At the fluid-solid interface we consider slip velocity. The governing nonlinear partial differential equations of the problem are converted into a system of nonlinear ordinary differential equations. Obtained series solutions of velocity are convergent. Impact of embedded parameters on fluid flow and skin friction coefficient is graphically presented. It is observed that axial and radial velocities have an opposite impact on the thickness coefficient of disk. Also surface drag force has a direct relationship with Hartman number.

    Full Text Available Effect of mass transfer in the magnetohydrodynamic flow of a Casson fluid over a porous stretching sheet is addressed in the presence of a chemical reaction. A series solution for the resulting nonlinear flow is computed. The skin friction coefficient and local Sherwood number are analyzed through numerical values for various parameters of interest. The velocity and concentration fields are illustrated for several pertinent flow parameters. We observed that the Casson parameter and Hartman number have similar effects on the velocity in a qualitative sense. We further analyzed that the concentration profile decreases rapidly in comparison to the fluid velocity when we increased the values of the suction parameter.

    This paper addresses mixed convective peristaltic flow of Jeffrey nanofluid in a channel with complaint walls. The present investigation includes the viscous dissipation, thermal radiation and Joule heating. Hall and ion slip effects are also taken into account. Related problems through long wavelength and low Reynolds number are examined for stream function, temperature and concentration. Impacts of thermal radiation, Hartman number, Brownian motion parameter, thermophoresis, Joule heating, Hall and ion slip parameters are investigated in detail. It is observed that velocity increases and temperature decreases with Hall and ion slip parameters. Further the thermal radiation on temperature has qualitatively similar role to that of Hall and ion slip effects.

    In this work a comparison between the response of alanine and Markus ionization chamber was carried out for measurements of the output factors (OF) of electron beams produced by a linear accelerator used for Intra-Operative Radiation Therapy (IORT). Output factors (OF) for conventional high-energy electron beams are normally measured using ionization chamber according to international dosimetry protocols. However, the electron beams used in IORT have characteristics of dose per pulse, energy spectrum and angular distribution quite different from beams usually used in external radiotherapy, so the direct application of international dosimetry protocols may introduce additional uncertainties in dosimetric determinations. The high dose per pulse could lead to an inaccuracy in dose measurements with ionization chamber, due to overestimation of ks recombination factor. Furthermore, the electron fields obtained with IORT-dedicated applicators have a wider energy spectrum and a wider angular distribution than the conventional fields, due to the presence of electrons scattered by the applicator's wall. For this reason, a dosimetry system should be characterized by a minimum dependence from the beam energy and from angle of incidence of electrons. This become particularly critical for small and bevelled applicators. All of these reasons lead to investigate the use of detectors different from the ionization chamber for measuring the OFs. Furthermore, the complete characterization of the radiation field could be accomplished also by the use of Monte Carlo simulations which allows to obtain detailed information on dose distributions. In this work we compare the output factors obtained by means of alanine dosimeters and Markus ionization chamber. The comparison is completed by the Monte Carlo calculations of OFs determined through the use of the Geant4 application "iort _ therapy" . The results are characterized by a good agreement of response of alanine pellets and Markus

    Full Text Available This article asks several questions: What is distinctive about Mark’s description about the rending of the curtain in the Jerusalem Temple during Jesus’ crucifixion?; What is his rhetorical strategy in doing so?; What role does the temple play in Jewish religion? What role does the Temple play in Jesus’ ministry and message?; and What is the context of the narrative about the torn temple curtain? The conclusion is that Mark utilises the description to demonstrate God’s judgement on the worship at the temple, but at the same time illustrates how the way between heaven and earth is opened at the moment of the death of God’s Son.Markus se onderskeidende beskrywing van die geskeurde tempelgordyn. Verskeie vrae kom in hierdie artikel aan die bod: Wat is onderskeidend in Markus se beskrywing van die gordyn in die Jerusalemtempel wat tydens Jesus se kruisiging skeur?; Wat is die evangelis se retoriese strategie?; Watter rol speel die tempel in Joodse godsdiens?; Watter rol speel dit in Jesus se bediening en boodskap?; en Wat is die konteks vir die narratief binne die Evangelie oor die gordyn wat skeur? Die gevolgtrekking is dat Markus die beskrywing benut om God se oordeel oor die tempel te demonstreer, maar terselfdertyd illustreer dit ook hoe die weg tussen hemel en aarde oopgebreek word in die oomblikke toe God se Seun sterf.

  9. Nanomechanics—the whole is more than the sum of its parts

    Science.gov (United States)

    2016-09-01

    Nanostructures, such as carbon nanotubes, are often added to polymers and composites to enhance their strength. The extreme mechanical properties of carbon nanotubes suggest an obvious rationale behind this approach. However as Markus Buehler and Isabelle Su at Massachusetts Institute of Technology in the US highlight in their recent topical review [1] the behaviour that renders nanomaterials soft or strong can be far from trivial, often involving interactions on a range of scales from macrostructures to nanostructures and—in the case of biostructures—the amino acids and proteins they are built from.

  15. A study of the woman in the crowd and her desperate courage (Mark 5:21–43

    Directory of Open Access Journals (Sweden)

    Robin G. Branch

    2013-11-01

    Full Text Available This article examines the cameo appearance of an unnamed woman in the gospel of Mark, a member of a crowd following Jesus (Mk 5:24b–34. Chronically ill and probably dying, she thinks she is inconspicuous. The text identifies her in terms of her gender, illness, covenant status, prolonged suffering and penury. Yet, a careful reading reveals her stealth, desperation, courage and eloquence − all elements of character and, it turns out, of a faith focused on Jesus. Combining both literary and canonical insights, this article shows how the story of the anonymous woman, set within the larger context of the healing of Jairus’ daughter, sheds light on the developing concepts of faith, fear, purity, discipleship, confession and family matters in Mark. The woman’s interaction with Jesus adds depth to Mark’s portrait of him and contributes to the ongoing revelation in Mark that Jesus is indeed the Son of God (Mk 1:1.Hierdie artikel ondersoek die reliëfverskyning van ’n naamlose vrou in die evangelie van Markus. Sy was deel van die skare wat Jesus gevolg het (Mark 5:24b–34. Omdat sy kronies siek en moontlik sterwend was, het sy gedink sy is onopvallend in die skare. Sy word in die teks geïdentifiseer in terme van haar geslag, siekte, verbondstatus, langdurige lyding en armoedige voorkoms. ’n Noukeurige bestudering van die gedeelte openbaar ook haar heimlikheid, desperaatheid, moed en welsprekendheid – alles eienskappe van ’n sterk karakter en, soos dit later blyk, haar gefokusde geloof op Jesus. Deur die letterkundige en kanonieke insigte te kombineer, wys die artikel hoe die verhaal van die anonieme vrou, gesien teen die agtergrond van die genesing van Jaïrus se dogtertjie, lig werp op die ontwikkelende konsepte van geloof, vrees, suiwerheid, dissipelskap, belydenis en familie-aangeleenthede in die boek Markus. Die vrou se interaksie met Jesus verskaf diepte aan Markus se uitbeelding van Hom en maak ’n bydrae tot Markus se

    In recent years, originally static and single purpose Wireless Sensor Networks have moved towards applications that need support for mobility and multiple purposes. These heterogeneous applications and services demand for a framework which distributes and discovers the various services, so that other pieces of equipment can use them. Markus Becker studies, extends, analytically models, simulates and employs the so called Trickle algorithm in measurements in a Wireless Sensor Network test bed for the service distribution. The obtained results apply to the application of the Trickle algorithm at

    2009-01-01

    A method is given for quantitatively rating the social acceptance of different options which are the matter of a complete preferential vote. Completeness means that every voter expresses a comparison (a preference or a tie) about each pair of options. The proposed method is proved to have certain desirable properties, which include: compliance with a majority principle, clone consistency, and continuity of the rates with respect to the data. One can view this method as a quantitative complement for a qualitative method introduced in 1997 by Markus Schulze. It is also related to certain methods of one-dimensional scaling or cluster analysis.

  5. Tailoring hospital marketing efforts to physicians' needs.

    Science.gov (United States)

    Mackay, J M; Lamb, C W

    1988-12-01

    Marketing has become widely recognized as an important component of hospital management (Kotler and Clarke 1987; Ludke, Curry, and Saywell 1983). Physicians are becoming recognized as an important target market that warrants more marketing attention than it has received in the past (Super 1987; Wotruba, Haas, and Hartman 1982). Some experts predict that hospitals will begin focusing more marketing attention on physicians and less on consumers (Super 1986). Much of this attention is likely to take the form of practice management assistance, such as computer-based information system support or consulting services. The survey results reported here are illustrative only of how one hospital addressed the problem of physician need assessment. Other potential target markets include physicians who admit patients only to competitor hospitals and physicians who admit to multiple hospitals. The market might be segmented by individual versus group practice, area of specialization, or possibly even physician practice life cycle stage (Wotruba, Haas, and Hartman 1982). The questions included on the survey and the survey format are likely to be situation-specific. The key is the process, not the procedure. It is important for hospital marketers to recognize that practice management assistance needs will vary among markets (Jensen 1987). Therefore, hospitals must carefully identify their target physician market(s) and survey them about their specific needs before developing and implementing new physician marketing programs. Only then can they be reasonably confident that their marketing programs match their customers' needs.

    2016-12-09

    Tunneling times in complex bianisotropic materials have been examined in detail, with absorption and dispersion taken into account. Tunneling is characterized by the dwell and the phase tunneling time. In this paper, we have developed a theoretical model and derived the appropriate expressions for each of these quantities, as well as a relationship between them and the corresponding expression for the energy density. The model has been verified through numerical calculations based on experimental data. We have distinguished cases in which the phases of transmitted and incident wave match each other, and showed that for small angles of incidence, the time that the wave spends inside the barrier can be approximated as a linear function of the barrier width. The Hartman effect has been detected, although for very thick layers of metamaterial. - Highlights: • We analyze the tunneling times in bianisotropic, dispersive and absorptive metamaterials. • Conditions of zero phase tunneling time are identified for a range of frequencies of interest. • The Hartman effect has been detected for very thick barriers of metamaterial.

    This year, the 48-hour film project (48hfp) returns to Geneva after a one-year hiatus. Organized by Neal Hartman and the CERN film-making club, Open Your Eyes Films, the 48hfp challenges teams of film-makers to write, shoot, soundtrack and edit a 4 to 7 minute film in 48 hours from 4 to 6 November.   At the start of the festival, contestants picked their film genre from a hat. The films will be screened on 8 and 9 November, with the awards presentation on the 9th. The winner will receive a trip to the US to compete in the international version of the competition. “There are so many short films being made now," says Hartman, “I think, however, that the 48hfp allows a critical creative mass to form. The result is that these 20 teams make 20 better films than if each participant were making their own." Each team draws a genre from a hat and is given a character, a prop and a line of dialogue that must appear in their film. The genres run the gamut from &am...

    1995-12-01

    In recent years, considerable efforts have been spent improving the precision and consistency in the whole process of calibration of high energy photon and electron beams (national protocols, primary calibration facilities ....). The reading in air of 5 different ionisation chambers (NE2532, NE2536, NE2571, PTWM23342, Markus) in an X-ray beam (RT50, HVL=0.35 mm Al) has been compared. Ali NE chambers were provided with a calibration factor Nk, the PTW chamber was directly calibrated in dose water ND,W. The polarisation and recombination effects were measured. In our reference field (ssd=4cm, field diameter 40 mm), the readings in air for the dedicated plan parallel chambers deviated by not more than 8%. The measurements with the NE2571 chamber did not correspond very well with the other measurements. For the equipment in our hospital, the dose rate in air for the reference field was measured from 1971 on and found to be very stable: 17.36 Gy/min (0.48) (1sd). An attempt was made to measure the BSF for the field defining cones used in clinical practice using a Markus plane parallel chamber, but the resulting BSF did not correspond to those reported in BJR/suppl. 17. Special attention has been be paid to the calibration of beams with field size comparable to the dimension of the chamber window- chamber body.

    Markus and Kitayama's (1991) theory of independent and interdependent self-construals had a major influence on social, personality, and developmental psychology by highlighting the role of culture in psychological processes. However, research has relied excessively on contrasts between North American and East Asian samples, and commonly used self-report measures of independence and interdependence frequently fail to show predicted cultural differences. We revisited the conceptualization and measurement of independent and interdependent self-construals in 2 large-scale multinational surveys, using improved methods for cross-cultural research. We developed (Study 1: N = 2924 students in 16 nations) and validated across cultures (Study 2: N = 7279 adults from 55 cultural groups in 33 nations) a new 7-dimensional model of self-reported ways of being independent or interdependent. Patterns of global variation support some of Markus and Kitayama's predictions, but a simple contrast between independence and interdependence does not adequately capture the diverse models of selfhood that prevail in different world regions. Cultural groups emphasize different ways of being both independent and interdependent, depending on individualism-collectivism, national socioeconomic development, and religious heritage. Our 7-dimensional model will allow future researchers to test more accurately the implications of cultural models of selfhood for psychological processes in diverse ecocultural contexts.

    In this study, a comparison was made between a plastic scintillator (BC400), a Faraday Cup (FC) and an ionization chamber (IC) used for routine proton dosimetry. Thin scintillators can be applied to proton dosimetry and consequently to proton therapy as relative dosimeters because of their water-equivalent nature, high energy-light conversion efficiency, low dimensions and good proportionality to the absorbed dose at low stopping powers. To employ such scintillators as relative dosimeters in proton therapy, the corrective factors must be applied to correct the quenching luminescence at the Bragg peak. A fine linear proportionality between the luminescence light yield Y and the proton flux in a thin (0.5 mm) scintillator for the 20 and 30 MeV proton beams were observed. The experimental peak/plateau ratios of Bragg Curve for 2, 1 and 0.5 mm scintillators with an accuracy of 0.5% were obtained to be 1.87, 1.91 and 2.30, respectively. With combination of the Markus chamber and the CR-39 detector, the peak/plateau ratio was improved to 3.26. The obtained data of the luminescence yield as a function of the specific energy loss is in agreement with the Craun-Birk's theory. Results show that the FC and Markus ionization chamber are in agreement within 4%, while the FC gives a lower dose evaluation. For a defined beam, the data for the fluence measurements are reproducible within a good accuracy.

    Particle physics research has many unique needs and sometimes has to create its own expertise to keep its systems running. For specialised areas like cryogenics and high-voltage technology, labs often run their own training courses. In line with this trend, CERN has started a series of International Trigger and Data Acquisition (ISOTDAQ) Schools. 2012 has seen the third ISOTDAQ School, which generated a lot of enthusiasm among the future generation of TDAQ experts.   Markus Joos tutoring a group of students. “Can I call you back in about an hour?

    The unidentified EGRET source 3EG J1828+0142, located at (l,b) ~ (31.9,5.8) (Hartman et al. 1999), is particularly enigmatic since it displays very high variability over timescales of months (Torres et al. 2000, Tompkins 1999) yet no blazar has been found within the 95% confidence contour of the gamma-ray location error-box (Punsly et al 2000). It also has an unusually steep gamma-ray spectral index of Gamma=2.76 +/- 0.39. It's relatively low latitude may be indicative of a galactic origin of the variable GeV flux. A multifrequency study of this source has been initiated and may reveal the presence of a novel type of compact object: a galactic 'microblazar'. X-ray data, especially those of high spatial resolution from CHANDRA, would be particularly useful in establishing such a connection.

    Wallace, James Kent

    2011-01-01

    This paper presents an optical configuration for a common-path phase-shifting interferometric wavefront sensor.1 2 This sensor has a host of attractive features which make it well suited for space-based adaptive optics. First, it is strictly reflective and therefore operates broadband, second it is common mode and therefore does not suffer from systematic errors (like vibration) that are typical in other interferometers, third it is a phase-shifting interferometer and therefore benefits from both the sensitivity of interferometric sensors as well as the noise rejection afforded by synchronous detection. Unlike the Shack-Hartman wavefront sensor, it has nearly uniform sensitivity to all pupil modes. Optical configuration, theory and simulations for such a system will be discussed along with predicted performance.

  17. On closed embeddings of free topological algebras

    2012-01-01

    Let $\\mathcal K$ be a complete quasivariety of completely regular universal topological algebras of continuous signature $\\mathcal E$ (which means that $\\mathcal K$ is closed under taking subalgebras, Cartesian products, and includes all completely regular topological $\\mathcal E$-algebras algebraically isomorphic to members of $\\mathcal K$). For a topological space $X$ by $F(X)$ we denote the free universal $\\mathcal E$-algebra over $X$ in the class $\\mathcal K$. Using some extension properties of the Hartman-Mycielski construction we prove that for a closed subspace $X$ of a metrizable (more generally, stratifiable) space $Y$ the induced homomorphism $F(X)\\to F(Y)$ between the respective free universal algebras is a closed topological embedding. This generalizes one result of V.Uspenskii concerning embeddings of free topological groups.

    2015-01-01

    We study generic two-dimensional dilaton gravity with a Maxwell field and prove its triviality for constant dilaton boundary conditions, despite of the appearance of a Virasoro algebra with non-zero central charge. We do this by calculating the canonical boundary charges, which turn out to be trivial, and by calculating the quantum gravity partition function, which turns out to be unity. We show that none of the following modifications changes our conclusions: looser boundary conditions, non-linear interactions of the Maxwell field with the dilaton, inclusion of higher spin fields, inclusion of generic gauge fields. Finally, we consider specifically the charged Jackiw--Teitelboim model, whose holographic study was pioneered by Hartman and Strominger, and show that it is non-trivial for certain linear dilaton boundary conditions. We calculate the entropy from the Euclidean path integral, using Wald's method and exploiting the chiral Cardy formula. The macroscopic and microscopic results for entropy agree with ...

    Benedetti, I.; Loi, N. V.; Malaguti, L.; Taddei, V.

    2017-02-01

    The paper deals with a second order integro-partial differential equation in Rn with a nonlocal, degenerate diffusion term. Nonlocal conditions, such as the Cauchy multipoint and the weighted mean value problem, are investigated. The existence of periodic solutions is also studied. The dynamic is transformed into an abstract setting and the results come from an approximation solvability method. It combines a Schauder degree argument with an Hartman-type inequality and it involves a Scorza-Dragoni type result. The compact embedding of a suitable Sobolev space in the corresponding Lebesgue space is the unique amount of compactness which is needed in this discussion. The solutions are located in bounded sets and they are limits of functions with values in finitely dimensional spaces.

    The tunneling of optical and acoustic phonons at normal incidence on a double-barrier is studied in this paper. Transmission coefficients and resonance conditions are derived theoretically under the assumption that the long-wavelength approximation is valid. It is shown that the behavior of the transmission coefficients for the symmetric double barrier has a Lorentzian form close to resonant frequencies and that Breit–Wigner's formula have a general validity in one-dimensional phonon tunneling. Authors also study the so-called generalized Hartman effect in the tunneling of long-wavelength phonons and show that this effect is a numerical artifact resulting from taking the opaque limit before exploring the variation with a finite barrier width. This study could be useful for the design of acoustic devices.

    2017-06-01

    Heat and mass transfer effects in the three-dimensional mixed convection flow of a viscoelastic fluid with internal heat source/sink and chemical reaction have been investigated in the present work. The flow generation is because of an exponentially stretching surface. Magnetic field normal to the direction of flow is considered. Convective conditions at the surface are also encountered. Appropriate similarity transformations are utilized to reduce the boundary layer partial differential equations into the ordinary differential equations. The homotopy analysis method is used to develop the solution expressions. Impacts of different controlling parameters such as ratio parameter, Hartman number, internal heat source/sink, chemical reaction, mixed convection, concentration buoyancy parameter and Biot numbers on the velocity, temperature and concentration profiles are analyzed. The local Nusselt and Sherwood numbers are sketched and examined.

    2016-01-01

    Gravity plays important roles in the evolution of molecular clouds. We present an acceleration mapping method to estimate the acceleration induced by gravitational interactions in molecular clouds based on observational data. We find that the geometry of a region has a significant impact on the behavior of gravity. In the Pipe nebula which can be approximated as a gas filament, we find that gravitational acceleration can effectively compress the end of this filament, which may have triggered star formation. We identify this as the "gravitational focusing" effect proposed by Burkert & Hartman (2004). In the sheet-like IC348-B3 region, gravity can lead to collapse at its edge, while in the centrally condensed NGC1333 cluster-forming region gravity can drive accretion towards the center. In general, gravitational acceleration tends to be enhanced in the localized regions around the ends of the filaments and the edges of sheet-like structures. Neglecting magnetic fields, these "gravitational focusing" and "ed...

    Full Text Available A theoretical analysis is presented for the peristaltic motion of a magneto-hydrodynamic (MHD non-Newtonian fluid in channel with complaint walls. The fluid obeys viscoelastic non-Newtonian model with Burger’s constitutive equation. The relevant equations are first developed and then solved using perturbation technique. Expressions of stream function and velocity components are constructed under the assumption that δ (characteristic ratio of transversal and axial scales of peristaltic motion is small. The results indicate the strong effects of Burger’s fluid parameter, Hartman number, Reynolds number, and complaint wall parameters on the velocity field and stream function. The obtained solutions are shown graphically for the different values of involved parameters.

    Full Text Available The aim of present paper is to study the series solution of time dependent MHD second grade incompressible nanofluid towards a stretching sheet. The effects of mixed convection and thermal radiation are also taken into account. Because of nanofluid model, effects Brownian motion and thermophoresis are encountered. The resulting nonlinear momentum, heat and concentration equations are simplified using appropriate transformations. Series solutions have been obtained for velocity, temperature and nanoparticle fraction profiles using Homotopy Analysis Method (HAM. Convergence of the acquired solution is discussed critically. Behavior of velocity, temperature and concentration profiles on the prominent parameters is depicted and argued graphically. It is observed that temperature and concentration profiles show similar behavior for thermophoresis parameter Νt but opposite tendency is noted in case of Brownian motion parameter Νb. It is further analyzed that suction parameter S and Hartman number Μ depict decreasing behavior on velocity profile.

    This paper is devoted to the magnetohydrodynamic (MHD) peristaltic transport of nanofluid in a channel with wall properties. Flow analysis is addressed in the presence of viscous dissipation, partial slip and Joule heating effects. Mathematical modelling also includes the salient features of Brownian motion and thermophoresis. Both analytic and numerical solutions are provided. Comparison between the solutions is shown in a very good agreement. Attention is focused to the Brownian motion parameter, thermophoresis parameter, Hartman number, Eckert number and Prandtl number. Influences of various parameters on skin friction coefficient, Nusselt and Sherwood numbers are also investigated. It is found that both the temperature and nanoparticles concentration are increasing functions of Brownian motion and thermophoresis parameters.

  8. Topology of Future Infinity in dS/CFT

    2013-01-01

    The dS/CFT proposal of Anninos, Hartman, and Strominger relates quantum Vasiliev gravity in dS_4 to a large N vector theory in three dimensions. We use this proposal to compute the Wheeler-de Witt wave function of a universe having a particular topology at future infinity. This amplitude is found to grow rapidly with the topological complexity of the spatial slice; this is due to the plethora of states of the Chern-Simons theory that is needed to impose the singlet constraint. Various mechanisms are considered which might ameliorate this growth, but none seems completely satisfactory. We also study the topology dependence in Einstein gravity by computing the action of complex instantons; the wave function then depends on a choice of contour through the space of metrics. The most natural contour prescription leads to a growth with genus similar to the one found in Vasiliev theory, albeit with a different power of Newton's constant.

  10. Magneto-Hydrodynamic Flow in a Two-Dimensional Inclined Rectangular Enclosure Heated and Cooled on Adjacent Walls

    Directory of Open Access Journals (Sweden)

    M.N Kherief

    2016-01-01

    Full Text Available Steady, laminar, natural-convection flow in the presence of a magnetic field in an inclined rectangular enclosure heated from one side and cooled from the adjacent side was considered. The governing equations were solved numerically for the stream function, vorticity and temperature using the finite-volume method for various Grashof and Hartman numbers and inclination angles and magnetic field directions. The results show that the orientation and the strength and direction of the magnetic field have significant effects on the flow and temperature fields. Counterclockwise inclination induces the formation of multiple eddies inside the enclosure significantly affecting the temperature field. Circulation inside the enclosure and therefore the convection become stronger as the Grashof number increases while the magnetic field suppresses the convective flow and the heat transfer rate.

    We study the tunneling of optical vibrational modes with transverse horizontal polarization that impinge, at a given angle, on a semiconductor heterostructure. We find a large influence of the Goos–Hänchen shift on tunneling times. In particular, a Goos–Hänchen shift larger than the barrier thickness is reported for the first time. The relation between Goos–Hänchen and Hartman effects is also discussed. The identity that equals the dwell time to the sum of transmission and interference times, previously derived for one-dimensional tunneling problems, is extended to the two-dimensional case. Closed-form expressions are developed for the relevant quantities. Instead of using the standard approach, the interference time is computed from the vibrational energy density. The present study could be useful for the design of semiconductor devices.

    The current work examines the peristaltic flow of Sutterby fluid in a planar symmetric channel. Electrically conducting fluid is considered via imposed magnetic field. An incompressible Sutterby fluid saturates the porous medium. Modified Darcy's law has been employed for the porous medium effect. The channel walls are compliant. Convective conditions of heat and mass transfer are imposed. Viscous dissipation and Joule heating are retained. Problem for large wavelength are numerically solved. The graphs are obtained for the velocity, temperature, concentration and heat transfer rate. Velocity and concentration profiles are observed to have opposite behavior for increasing Darcy number. It is found that the effect of Hartman number on the velocity and temperature profiles is similar. Further heat transfer coefficient strengthened when heat transfer Biot number is increased.

    Petersen, Jakob; Pollak, Eli

    2017-08-15

    Attosecond ionization experiments have not resolved the question "What is the tunneling time?". Different definitions of tunneling time lead to different results. Second, a zero tunneling time for a material particle suggests that the nonrelativistic theory includes speeds greater than the speed of light. Chemical reactions, occurring via tunneling, should then not be considered in terms of a nonrelativistic quantum theory calling into question quantum dynamics computations on tunneling reactions. To answer these questions, we define a new experimentally measurable paradigm, the tunneling flight time, and show that it vanishes for scattering through an Eckart or a square barrier, irrespective of barrier length or height, generalizing the Hartman effect. We explain why this result does not lead to experimental measurement of speeds greater than the speed of light. We show that this tunneling is an incoherent process by comparing a classical Wigner theory with exact quantum mechanical computations.

  15. Properties of group delay for photon tunneling through dispersive metamaterial barriers

    Science.gov (United States)

    Wang, Xinglin; Wang, Huisheng; Zheng, Fanong

    2017-01-01

    We make a detailed investigation on properties of the group delay for photon tunneling through dispersive metamaterial barriers by employing stationary phase method. Due to the anomalous dispersion of the different barriers, it is found that the group delay is positive for double negative metamaterial (DNM) barrier, while for single negative metamaterial (SNM) and negative-zero-positive index metamaterial (NZPIM) barriers, they can change from negative to positive with variations of both frequency and incident angle. The lateral shift for the photon tunneling has also been studied, whose sign is found not to dominate the sign of the group delay. It is further confirmed that the group delay tends to a saturation value with increasing barrier length because of Hartman effect. These results may provide some ideas for further study on the photon tunneling, suggest the analogous phenomena of valence electron in graphene, and produce some potential application in integrated optics and optical devices.

    Clay minerals are fundamental constituents of life, not only as possible actors in the development of life on the Earth (Cairns-Smith and Hartman, 1986), but mainly because they are essential constituents of soils, the interface between the solid planet and the continental biosphere. Many, many authors have devoted themselves to the study of clays and clay minerals since the publication of the early modern studies by Grim (1953, 1962) and Millot (1964). In those years two very important associations were established in Europe (Association Internationale pour l'Etude des Argiles, AIPEA) and in the USA (Clay Mineral Society, CMS). The importance of these societies is to put together people that work in very different fields (agronomy, geology, geochemistry, industry, etc.), but with a common language (clays), very useful in scientific work. Currently excellent texts are being published, but introductory notes are also available on the web (Schroeder, 1998).

    The role of surface relaxation on habit controlling energetics and growth morphology are investigated within the framework of Burton-Cabrera-Frank (BCF) and Hartman-Perdok (HP) models. The habit controlling energetics has been calculated using first principles method. The growth morphology obtained using BCF theory shows that the structural relaxation has considerable effect on growth morphology. The relaxed growth morphology obtained using BCF model match with the experimental result from vapour phase. On the other hand the shape obtained using HP model does not correspond with the experimental shape. Observed polar growth morphology of urea crystal has been discussed particularly in the context of different atomic environments of (111) and (111) faces.

  3. Instability in electromagnetically driven flows Part I

    Gissinger, Christophe; Fauve, Stephan

    2016-01-01

    The MHD flow driven by a travelling magnetic field (TMF) in an annular channel is investigated numerically. For sufficiently large magnetic Reynolds number Rm, or if a large enough pressure gradient is externally applied, the system undergoes an instability in which the flow rate in the channel dramatically drops from synchronism with the wave to much smaller velocities. This transition takes the form of a saddle-node bifurcation for the time-averaged quantities. In this first paper, we characterize the bifurcation, and study the stability of the flow as a function of several parameters. We show that the bifurcation of the flow involves a bistability between Poiseuille-like and Hartman-like regimes, and relies on magnetic flux expulsion. Based on this observation, new predictions are made for the occurrence of this stalling instability.

    This paper addresses mixed convective peristaltic flow of Jeffrey nanofluid in a channel with complaint walls. The present investigation includes the viscous dissipation, thermal radiation and Joule heating. Hall and ion slip effects are also taken into account. Related problems through long wavelength and low Reynolds number are examined for stream function, temperature and concentration. Impacts of thermal radiation, Hartman number, Brownian motion parameter, thermophoresis, Joule heating, Hall and ion slip parameters are investigated in detail. It is observed that velocity increases and temperature decreases with Hall and ion slip parameters. Further the thermal radiation on temperature has qualitatively similar role to that of Hall and ion slip effects. - Highlights: • Peristalsis in the presence of Jeffery nanofluid is formulated. • Compliant properties of channel walls are addressed. • Impact of Hall and ion slip effects is outlined. • Influence of Joule heating and radiation is investigated. • Mixed convection for both heat and mass transfer is present.

    Ma, Xiongfeng

    2011-01-01

    A combinatorial design is a family of sets that are almost disjoint, which is applied in pseudo random number generations and randomness extractions. The parameter, $\\rho$, quantifying the overlap between the sets within the family, is directly related to the length of a random seed needed and the efficiency of an extractor. Nisan and Wigderson proposed an explicit construction of designs in 1994. Later in 2003, Hartman and Raz proved a bound of $\\rho\\le e^2$ for the Nisan-Wigderson construction. In this work, we prove a tighter bound of $\\rho

    Available type material of Prionospio heterobranchia Moore, 1907, P. ( Prionospio) texana Hartman, 1951, P. spongicola Wesenberg-Lund, 1958 and P. ( P.) newportensis Reish, 1959, as well as newly collected material from the Southern Gulf of Mexico and Chetumal Bay in the Caribbean Sea, was examined. Several important differences were found between P. heterobranchia, P. ( Prionospio) texana, P. spongicola and P. ( P.) newportensis, and as a result, these three species are removed from synonymy with P. heterobranchia Moore, 1907, and redescribed and reinstated as valid species. In addition, three new species were identified and described: P. caribensis sp. nov., P. rosariae sp. nov. and P. jamaicensis sp. nov. A key to all species of Prionospio with five pairs of branchiae is provided.

    2015-01-01

    Type material of several polychaete species described by Enrique Rioja from Mexican coasts are lost, and the current status of some species is doubtful. Nereis oligohalina (Rioja, 1946) was described from the Gulf of Mexico, but it has been considered a junior synonym of Nereis occidentalis Hartman, 1945, or regarded as a distinct species with an amphiamerican distribution. On the other hand, Nereis garwoodi González-Escalante & Salazar-Vallejo, 2003, described from Chetumal Bay, Caribbean coasts, could be confused with Nereis oligohalina. In order to clarify these uncertainties, Nereis oligohalina is redescribed based on specimens from the Mexican Gulf of Mexico, including a proposed neotype; further, Nereis garwoodi is redescribed including the selection of lectotype and paralectotypes, and Nereis confusa sp. n. is described with material from the Gulf of California. A key for the identification of similar species and some comments about speciation in nereidid polychaetes are also included.

    The nereidid polychaete genus Namalycastis Hartman, 1959 has been recorded almost exclusively in non-marine environments. This genus includes species having four pairs of tentacular cirri, and its species mainly differ by the relative size of dorsal cirri in posterior chaetigers. Namalycastis occulta n. sp. is described based upon non-mature and mature specimens collected in the intertidal from Chetumal Bay, Quintana Roo, Mexico. Its distinctive features are the lack of notopodial spinigers, eyes, and teeth in the mandibles. Namalycastis borealis Glasby was found in Tamalcab Island, Chetumal Bay and it is the first record for Mexico. Analyses of the intraspecific variability, a key to the known species in the Grand Caribbean region, and commentaries about some taxonomic topics are also included.

  10. Analysis of the Magnetic Field Effect on Entropy Generation at Thermosolutal Convection in a Square Cavity

    2011-05-01

    Full Text Available Thermosolutal convection in a square cavity filled with air and submitted to an inclined magnetic field is investigated numerically. The cavity is heated and cooled along the active walls with a mass gradient whereas the two other walls of the cavity are adiabatic and insulated. Entropy generation due to heat and mass transfer, fluid friction and magnetic effect has been determined in transient state for laminar flow by solving numerically the continuity, momentum energy and mass balance equations, using a Control Volume Finite—Element Method. The structure of the studied flows depends on four dimensionless parameters which are the Grashof number, the buoyancy ratio, the Hartman number and the inclination angle. The results show that the magnetic field parameter has a retarding effect on the flow in the cavity and this lead to a decrease of entropy generation, Temperature and concentration decrease with increasing value of the magnetic field parameter.

    2017-06-01

    Full Text Available This paper focuses on solving the fluid flow and heat transfer equations inside a two-dimensional square enclosure containing three hot obstacles affected by gravity and magnetic force placed on a ramp using Boltzmann method (LBM applying multiple relaxation times (MRT. Although, the Lattice Boltzmann with MRT is a complex technique, it is a relatively new, stable, fast and high-accurate one. The main objective of this research was to numerically model the fluid flow and ultimately obtaining the velocity field, flow and temperature contour lines inside a two-dimensional enclosure. The results and their comparisons for different types of heat transfer revealed that free or forced heat transfer has a considerable impact on the heat transfer and stream lines. This can be controlled by modifying the Richardson number. It is revealed that changing the intensity of the magnetic field (Hartman number has an appreciable effect on the heat transfer.

    We study the time evolution of cMERA (continuous MERA) under quantum quenches in free field theories. We calculate the corresponding holographic metric using the proposal in arXiv:1208.3469 and confirm that it qualitatively agrees with its gravity dual given by a half of the AdS black hole spacetime, argued by Hartman and Maldacena in arXiv:1303.1080. By doubling the cMERA for the quantum quench, we give an explicit construction of finite temperature cMERA. We also study cMERA in the presence of chemical potential and show that there is an enhancement of metric in the infrared region corresponding to the Fermi energy.

  14. Entanglement, Tensor Networks and Black Hole Horizons

    Molina-Vilaplana, Javier

    2014-01-01

    We elaborate on a previous proposal by Hartman and Maldacena on a tensor network which accounts for the scaling of the entanglement entropy in a system at a finite temperature. In this construction, the ordinary entanglement renormalization flow given by the class of tensor networks known as the Multi Scale Entanglement Renormalization Ansatz (MERA), is supplemented by an additional entanglement structure at the length scale fixed by the temperature. The network comprises two copies of a MERA circuit with a fixed number of layers and a pure matrix product state which joins both copies by entangling the infrared degrees of freedom of both MERA networks. The entanglement distribution within this bridge state defines reduced density operators on both sides which cause analogous effects to the presence of a black hole horizon when computing the entanglement entropy at finite temperature in the AdS/CFT correspondence. The entanglement and correlations during the thermalization process of a system after a quantum q...

  15. On the Traversal Time of Barriers

    Aichmann, Horst; Nimtz, Günter

    2014-06-01

    Fifty years ago Hartman studied the barrier transmission time of wave packets (J Appl Phys 33:3427-3433, 1962). He was inspired by the tunneling experiments across thin insulating layers at that time. For opaque barriers he calculated faster than light propagation and a transmission time independent of barrier length, which is called the Hartman effect. A faster than light (FTL or superluminal) wave packet velocity was deduced in analog tunneling experiments with microwaves and with infrared light thirty years later. Recently, the conjectured zero time of electron tunneling was claimed to have been observed in ionizing helium inside the barrier. The calculated and measured short tunneling time arises at the barrier front. This tunneling time was found to be universal for elastic fields as well as for electromagnetic fields. Remarkable is that the delay time is the same for the reflected and the transmitted waves in the case of symmetric barriers. Several theoretical physicists predicted this strange nature of the tunneling process. However, even with this background many members of the physics community do not accept a FTL signal velocity interpretation of the experimental tunneling results. Instead a luminal front velocity was calculated to explain the FTL experimental results frequently. However, Brillouin stated in his book on wave propagation and group velocity that the front velocity is given by the group velocity of wave packets in the case of physical signals, which have only finite frequency bandwidths. Some studies assumed barriers to be cavities and the observed tunneling time does represent the cavity lifetime. We are going to discus these continuing misleading interpretations, which are found in journals and in textbooks till today.

    Mixed convection in a lid-driven square cavity filled with Cu-water nanofluid and subjected to inclined magnetic field is investigated in this paper. Partial slip effect is considered along the lid driven horizontal walls. A constant heat flux source on the left wall is considered, meanwhile the right vertical wall is cooled isothermally. The remainder cavity walls are thermally insulted. A control finite volume method is used as a numerical appliance of the governing equations. Six pertinent parameters were studied these; the orientation of the magnetic field (Φ=0-360°), Richardson number (Ri=0.001-1000), Hartman number (Ha=0-100), the size and position of the heat source (B=0.2-0.8, D=0.3-0.7, respectively), nanoparticles volume fraction (ϕ=0.0-0.1), and the lid-direction of the horizontal walls (λ=±1) where the positive sign means lid-driven to the right while the negative sign means lid-driven to the left. The results show that the orientation and the strength of the magnetic field can play a significant role in controlling the convection under the effect of partial slip. It is also found that the natural convection decreases with increasing the length of the heat source for all ranges of the studied parameters, while it is do so due to the vertical distance up to Hartman number of 50, beyond this value the natural convection decreases with lifting the heat source narrower to the top wall.

    2000-01-01

    In medical radiation physics, an increasing number of Monte Carlo codes are being used, which requires intercomparison between them to evaluated the accuracy of the simulated results against benchmark experiments. The Monte Carlo code EGS4, commonly used to simulate electron beams from medical linear accelerators, was compared with GEANT3 and MCNP4b. Intercomparison of electron energy spectra, angular and spatial distribution were carried out for the Siemens KD2 linear accelerator, at beam energies of 10 and 15 MeV for a field size of 10x10 cm2. Indirect validation was performed against electron depth doses curves and beam profiles measured in a MP3-PTW water phantom using a Markus planar chamber. Monte Carlo isodose lines were reconstructed and compared to those from commercial treatment planning systems (TPS's) and with experimental data.

    Serious scientific games, especially those that include a virtual apprenticeship component, provide players with realistic experiences in science. This article discusses how science games can influence learning about science and the development of science-oriented possible selves through repeated practice in professional play and through social influences (e.g., peer groups). We first review the theory of possible selves (Markus and Nurius 1986) and discuss the potential of serious scientific games for influencing the development of scientific possible selves. As part of our review, we present a forensic game that inspired our work. Next we present a measure of scientific possible selves and assess its reliability and validity with a sample of middle-school students (N=374). We conclude by discussing the promise of science games and the development of scientific possible selves on both the individual and group levels as a means of inspiring STEM careers among adolescents.

    Full Text Available The theory of control analyzes the proprieties of commanded systems. Problems of optimal control (OC have been intensively investigated in the world literature for over forty years. During this period, series of fundamental results have been obtained, among which should be noted the maximum principle (Pontryagin et al., 1962 and dynamic programming (Bellman, 1963. For many of the problems of the optimal control theory (OCT, adequate solutions are found (Bryson and Yu-chi, 1969, Lee and Markus, 1967, Gabasov and Kirillova, 1977, 1978, 1980. Results of the theory were taken up in various fields of science, engineering, and economics. The present paper aims at extending the constructive methods of Balashevich et al., (2000 that were developed for the problems of optimal control with the bounded initial state is not fixed are considered.

    Right to left: Thomas Wobmann and Markus Zemp visit the LHC tunnel at CERN with G nther Dissertori and Marcel Wyler of ETH Zurich. Their visit was part of the top prize for a competition organised by the ETH department of physics to coincide with its open day in June. Residents of Zurich and surrounding Swiss cantons were invited to answer five physics questions broadcast on local radio and the Internet the week before the open day. The two winners' reward for knowing who did not believe that God plays dice, among other things, was a flight offered by Swiss International Air Lines to Geneva and a VIP tour of CERN. One highlight was a trip to the underground site of the future CMS experiment, where the scale of the enormous cavern makes construction machines look like children's toys.

    Skin-sparing benefits derived from the use of megavoltage photon beams can be strongly reduced when filters are inserted between the source and the patient. The use of plastic masks for immobilizing the patient is the most important cause of this reduction in head and neck treatments. The influence of thermoplastics, commercially available for patient immobilization systems (Orfit Raycast (Luxilon Ind. Co.), Posicast (Sinmed bv) and Optimold (WFR Aquaplast Corp.)), on the patient skin dose value has been investigated by using an NE2534 'Markus' chamber. Indicative measurements with moulded masks (carried out with 2-mm Orfit and 3.2-mm Optimold layers) show significant differences between masks moulded with the two thermoplastics.

    Three dosimetric systems were compared regarding dosimetry of small circular x ray fields used in radiosurgery. The dosimetric parameters for circular cones, with diameters ranging from 7 to 30 mm, were acquired using a 6 MV Clinac 600 C linear accelerator. For the measurement of tissue maximum ratios, total scatter factor and radiation field profile, Kodak X-Omat type V radiographic films, and ionization chamber of 0.1 cm{sup 3} and a plane parallel ionization chamber type Markus were used. The plane parallel ionization chamber showed satisfactory results for measurement of tissue maximum ratios and total scatter only for cone sizes larger than 11 mm in diameter. Beam profile showed better spatial resolution when films ere used. The main physical parameters of small circular fields used in radiosurgery can be obtained by combining the dosimetry results of radiation therapy equipment used in current clinical practice.

  4. Essentializing the binary self: individualism and collectivism in cultural neuroscience.

    2013-01-01

    Within the emerging field of cultural neuroscience (CN) one branch of research focuses on the neural underpinnings of "individualistic/Western" vs. "collectivistic/Eastern" self-views. These studies uncritically adopt essentialist assumptions from classic cross-cultural research, mainly following the tradition of Markus and Kitayama (1991), into the domain of functional neuroimaging. In this perspective article we analyze recent publications and conference proceedings of the 18th Annual Meeting of the Organization for Human Brain Mapping (2012) and problematize the essentialist and simplistic understanding of "culture" in these studies. Further, we argue against the binary structure of the drawn "cultural" comparisons and their underlying Eurocentrism. Finally we scrutinize whether valuations within the constructed binarities bear the risk of constructing and reproducing a postcolonial, orientalist argumentation pattern.

    Trindade, A.; Rodrigues, P.; Alves, C.; Chaves, A.; Lopes, M. C.; Oliveira, C.; Peralta, L.

    In medical radiation physics, an increasing number of Monte Carlo codes are being used, which requires intercomparison between them to evaluated the accuracy of the simulated results against benchmark experiments. The Monte Carlo code EGS4, commonly used to simulate electron beams from medical linear accelerators, was compared with GEANT3 and MCNP4b. Intercomparison of electron energy spectra, angular and spatial distribution were carried out for the Siemens KD2 linear accelerator, at beam energies of 10 and 15 MeV for a field size of 10x10 cm2. Indirect validation was performed against electron depth doses curves and beam profiles measured in a MP3-PTW water phantom using a Markus planar chamber. Monte Carlo isodose lines were reconstructed and compared to those from commercial treatment planning systems (TPS's) and with experimental data.

    The CIAS Chalonge Workshop `Dark Matter in the Universe and Universal Properties of Galaxies: Theory and Observations', was held at the Meudon Ch^ateau of Observatoire de Paris on 8-11 June 2010. The Workshop approached DM in a fourfold way: astronomical observations of DM structures (galaxy properties, halos, rotation curves and density profiles), DM numerical simulations (with and without baryons), theoretical astrophysics and cosmology (kinetic theory, Boltzmann-Vlasov evolution), astroparticle physics. Peter Biermann, Alfonso Cavaliere, Hector J. de Vega, Gianfranco Gentile, Chandra Jog, Andrea Lapi, Paolo Salucci, Norma G. Sanchez, Pasquale Serpico, Rainer Stiele, Janine van Eymeren and Markus Weber present here their highlights of the Workshop. The summary and conclusions by H. J. de Vega and N. G. Sanchez stress among other points the growing evidence that DM particles have a mass in the keV scale and that those keV scale particles naturally produce the small scale structures observed in galaxies.

  7. Smart structures for shock wave attenuation using ER inserts

    2001-08-01

    This Paper demonstrates the possibility of shock wave attenuation propagating through a smart structure that incorporates ER insert. The wave transmission of ER inserted beam is theoretically derived using Mead & Markus model and the theoretical results are compared with the finite element analysis results. To experimentally verify the shock wave attenuation, ER insert in an aluminum plate is made and two piezoceramic disks are used as transmitter and receiver of the wave. The transmitter sends a sine pulse signal such that a component of shock wave travels through the plate structure and the receiver gets the transmitted wave signal. Wave propagation of the ER insert can be adjusted by changing the applied electric field on the ER insert. Details of the experiment are addressed and the possibility of shock wave attenuation is experimentally verified. This kind of smart structure can be used for warship and submarine hull structures to protect fragile and important equipment.

    An experimental intercomparison between the proton response of LiF TLD-100 and alanine detectors is reported. The investigations were performed with LiF chips and alanine pellets in a 62 MeV proton beam at the Paul Scherrer Institut in Villigen (CH). Results were compared with reference dosimetry provided by Markus type parallel plate ionization chamber. The response of the detectors was studied, in a phantom, at different beam penetration depths in pristine and modulated beams. For both alanine and TL detectors, within the experimental uncertainty of the measurements, no significant energy dependence in the response was observed down to the Bragg peak region. The sensitivity of alanine and LiF detectors to protons was measured in the centre of modulated Bragg peak and no significant difference was found with respect to {sup 60}Co. Contrary to LiF, alanine also offers a remarkable tissue equivalence which favours its choice for in-phantom dosimetry. (author).

  11. Experimental determination of the effective point of measurement for various detectors used in photon and electron beam dosimetry

    Science.gov (United States)

    Khee Looe, Hui; Harder, Dietrich; Poppe, Björn

    2011-07-01

    The subject of this study is the 'shift of the effective point of measurement', Δz, well known as a method of correction compensating for the 'displacement effect' in photon and electron beam dosimetry. Radiochromic EBT 1 films have been used to measure the 'true' TPR curves of 6 and 15 MV photons and 6 and 9 MeV electrons in the solid water-equivalent material RW3. For the Roos and Markus chambers, the cylindrical 'PinPoint', 'Semiflex' and 'Rigid-Stem' chambers, the 2D-Array and the E-type silicon diode (all from PTW-Freiburg), the positions of the effective points of measurement have been determined by direct or indirect comparison between their TPR curves and those of the EBT 1 film. Both for the Roos and Markus chambers, we found Δz = (0.4 ± 0.1) mm, which confirms earlier experimental and Monte Carlo results, but means a shortcoming of the 'water-equivalent window thickness' formula. For the cylindrical chambers, the ratio Δz/r was observed to increase with r, confirming a recent Monte Carlo prediction by Tessier (2010 E2-CN-182, Paper no 147, IDOS, Vienna) as well as the experimental observations by Johansson et al (1978 IAEA Symp. Proc. (Vienna) IAEA-SM-222/35 pp 243-70). According to a theoretical consideration, the shift of the effective point of measurement from the reference point of the detector is caused by a gradient of the fluence of the ionizing particles. As the experiments have shown, the value of Δz depends on the construction of the detector, but remains invariant under changes of radiation quality and depth. Other disturbances, which do not belong to the class of 'gradient effects', are not corrected by shifting the effective point of measurement.

    Plane-parallel ionisation chambers are regularly used to conduct relative dosimetry measurements for therapeutic kilovoltage beams during commissioning and routine quality assurance. This paper presents the first quantification of the polarity effect in kilovoltage photon beams for two types of commercially available plane-parallel ionisation chambers used for such measurements. Measurements were performed at various depths along the central axis in a solid water phantom and for different field sizes at 2 cm depth to determine the polarity effect for PTW Advanced Markus and Roos ionisation chambers (PTW-Freiburg, Germany). Data was acquired for kilovoltage beams between 100 kVp (half-value layer (HVL)  =  2.88 mm Al) and 250 kVp (HVL  =  2.12 mm Cu) and field sizes of 3-15 cm diameter for 30 cm focus-source distance (FSD) and 4  ×  4 cm(2)-20  ×  20 cm(2) for 50 cm FSD. Substantial polarity effects, up to 9.6%, were observed for the Advanced Markus chamber compared to a maximum 0.5% for the Roos chamber. The magnitude of the polarity effect was observed to increase with field size and beam energy but was consistent with depth. The polarity effect is directly influenced by chamber design, with potentially large polarity effects for some plane-parallel ionisation chambers. Depending on the specific chamber used, polarity corrections may be required for output factor measurements of kilovoltage photon beams. Failure to account for polarity effects could lead to an incorrect dose being delivered to the patient.

    Increasing forest carbon-sequestration has become an important measure to address the climate changes. Based on the assumptions of planting in bare lands with medium site conditions and management intensity, this research analyzed the impact of carbon subsidies and carbon tax policies on Chinese fir (Cun-ninghamia lanceolata) plantation through the Chinese fir growth model and the modified Hartman model. The research findings indicated that raising carbon price had little effect on the optimal rotation and carbon supply in a comparatively large price range because the profit from the wood was much higher than that from carbon sequestration. However, the optimal rotation and carbon supply showed a tendency to rise; the land expected value was positively correlated with the carbon price. Because of the implementation of carbon subsidies and carbon tax policies, the values of forest land had been increased. Compared with other types of land use such as agricultural land, more land should be used as forest land.%增加森林碳汇已经成为应对气候变化的重要举措.基于在中等立地条件和经营强度的土地类型上进行裸地造林的假设,运用杉木 Cunninghamia lanceolata 生长模型和修正的 Faustman-Hartman 模型分析碳补贴和碳税政策对杉木人工林的影响.研究表明:由于木材收益远大于碳汇收益,所以在较大的价格区间内碳汇价格增加对于最优轮伐期和碳供给的影响不显著,但最优轮伐期和碳供给量呈上升趋势;土地期望值与碳汇价格呈正相关.由于碳补贴和碳税政策的实施,林地的价值在增长,与其他土地利用类型如农业用地相比,更多的土地将被用作林业用地.

    This paper proposed the multi-index nonlinear control design method for simple-input simple-output (SISO) differential algebraic system with implicit fimction (DASM1NC) in order to ensure all states of the system have excellent dynamic and steady-state performances. By means of Hartman-Grobman theorem, this paper deduced the relationship between parameter matrix (cl, C2) and characteristic roots of linear approximate system to nonlinear differential algebraic system. Therefore, the essence of DASMINC is revealed. Applying the method to single machine infinite bus system, which belong to a nonlinear differential algebraic model, a multi-index nonlinear excitation control law was designed. Simulation results show that the control law can enhance the stability of the system, improve the regulative precision of generator terminal voltage, and make each state trace for their given values rapidly. It manifests that the proposed method can effectively coordinate the dynamic and the steady-state performances for nonlinear differential algebraic system.%针对含隐函数的单输入单输出微分代数系统,提出多指标非线性控制设计方法,以确保各状态量均具有良好的动、静态性能。借助于哈特曼-格鲁勃曼(Hartman-Grobmanl定理推证非线性微分代数系统对应的一次近似系统的特征根与输出函数中参数矩阵(c1,c2)之间的关系,从而揭示了该方法的实质。将该方法应用于非线性微分代数模型的发电机单机无穷大系统中,设计了一个多指标的非线性励磁控制律。仿真表明:该控制律既能增强系统的稳定性,又能提高发电机机端电压控制精度,使各个状态量快速地追踪其给定值。说明该方法能有效地解决微分代数系统的动、静态性能的协调问题。

    A multi-index coordinated control method based nonlinear differential algebraic model for single machine infinite bus power system with thyristor controlled braking resistor (TCBR) is proposed. By means of Hartman-Grobman theorem, differential algebraic system multi-index nonlinear control (DASMINC) design method can reassign the closed-loop system eigenvalues of linear approximate system to the nonlinear differential algebraic system via appropriately selecting output function parameter matrix. Therefore, the system can access to good control performance and strong anti-interference ability.

    2016-07-01

    As a lesson from the Fukushima nuclear disaster, a radical change has taken place in climate and energy policy in Germany since 2011. This is characterized by the phase-out of the nuclear energy, which is fixed by the 13th Atomic Enforcement Act, by the end of 2022. This entails a multitude of complex legal questions and subsequent problems. The latest decisions are the forthcoming decisions of the BVerfG on the constitutional consistency of the nuclear phase-out law and nuclear fuel tax, Vattenfall's much discussed arbitration award before the ICSID arbitration court, and controversial legal questions both in the context of the decommissioning and dismantling of nuclear power plants and the disposal of highly radioactive waste. In addition, the moral-ethical evaluation of the nuclear phase-out and the power turn-around is the focus of the interdisciplinary approach. The problem clusters are analyzed by the contributions of the anthology. He documents a conference organized by Professor Dr. Markus Ludwig, which took place on April 8, 2016, at the University of Wuerzburg, within the framework of a project funded by the Fritz Thyssen Stiftung (''The Law of the Energy Transition''). [German] Als Lehre aus der Atomkatastrophe von Fukushima ist in Deutschland seit 2011 ein radikaler Wandel in der Klima- und Energiepolitik erfolgt. Praegend hierfuer ist der durch die 13. Atomgesetznovelle fixierte Ausstieg aus der Kernenergie bis Ende 2022. Damit verbunden ist eine Vielzahl komplexer Rechtsfragen und Folgeprobleme. Aktuelle Schlaglichter bilden die anstehenden Entscheidungen des BVerfG zur Verfassungskonformitaet von Atomausstiegsgesetz und Kernbrennstoffsteuer, die vieldiskutierte Schiedsklage von Vattenfall vor dem ICSID-Schiedsgericht sowie die kontroversen Rechtsfragen sowohl im Kontext der Stilllegung und des Rueckbaus von Kernkraftwerken als auch hinsichtlich der Endlagerung hochradioaktiver Abfaelle.

    Reynolds, T; Gerbi, B; Higgins, P [UniversityMinnesota, Minneapolis, MN (United States)

    2014-06-01

    Purpose: To compare the surface dose (SD) measured using a PTW 30-360 extrapolation chamber with different commonly used dosimeters (Ds): parallel plate ion chambers (ICs): RMI-449 (Attix), Capintec PS-033, PTW 30-329 (Markus) and Memorial; TLD chips (cTLD), TLD powder (pTLD), optically stimulated (OSLs), radiochromic (EXR2) and radiographic (EDR2) films, and to provide an intercomparison correction to Ds for each of them. Methods: Investigations were performed for a 6 MV x-ray beam (Varian Clinac 2300, 10x10 cm{sup 2} open field, SSD = 100 cm). The Ds were placed at the surface of the solid water phantom and at the reference depth dref=1.7cm. The measurements for cTLD, OSLs, EDR2 and EXR2 were corrected to SD using an extrapolation method (EM) indexed to the baseline PTW 30-360 measurements. A consistent use of the EM involved: 1) irradiation of three Ds stacked on top of each other on the surface of the phantom; 2) measurement of the relative dose value for each layer; and, 3) extrapolation of these values to zero thickness. An additional measurement was performed with externally exposed OSLs (eOSLs), that were rotated out of their protective housing. Results: All single Ds measurements overestimated the SD compared with the extrapolation chamber, except for Attix IC. The closest match to the true SD was measured with the Attix IC (− 0.1%), followed by pTLD (0.5%), Capintec (4.5%), Memorial (7.3%), Markus (10%), cTLD (11.8%), eOSL (12.8%), EXR2 (14%), EDR2 (14.8%) and OSL (26%). The EM method of correction for SD worked well for all Ds, except the unexposed OSLs. Conclusion: This EM cross calibration of solid state detectors with an extrapolation or Attix chamber can provide thickness corrections for cTLD, eOSLs, EXR2, and EDR2. Standard packaged OSLs were not found to be simply corrected.

    This paper numerically investigates the effect of an externally evanescent magnetic field on total entropy generation in a fluid enclosed in a square cavity by using a control volume finite element method to solve the conservation equations at Prandtl number of 0·71. The values of relaxation time of the magnetic field are chosen, so that the Lorentz force acts only in the transient state of entropy generation in natural convection. The total entropy generation was calculated for, fixed value of irreversibility distribution ratio, different relaxation time varying from 0 to 1/5 and Grashof number varying from 104 to 105. The effects of the Hartman number and the magnetic field inclination angle on the evolution of total entropy generation throughout the transient regime were investigated. Results show that the application of evanescent magnetic field not only suppresses the fluctuation of the total entropy generation in the transient state, but also reduces the gap for magnetic field relaxation time less than 1/10.

    Full Text Available The linear stability of plan Poiseuille flow of an electrically conducting viscoelastic fluid in the presence of a transverse magnetic field is investigated numerically. The fourth-order Sommerfeld equation governing the stability analysis is solved by spectral method with expansions in lagrange’s polynomials, based on collocation points of Gauss-Lobatto. The critical values of Reynolds number, wave number and wave speed are computed. The results are shown through the neutral curve. The main purpose of this work is to check the combined effect of magnetic field and fluid’s elasticity on the stability of the plane Poiseuille flow. Based on the results obtained in this work, the magnetic field is predicted to have a stabilizing effect on the Poiseuille flow of viscoelastic fluids. Hence, it will be shown that for second-order fluids (K 0 is that the critical Reynolds numbers Rec increase when the Hartman number M increases for certain value of elasticity number K and decrease for others. The latter result is in contrast to previous studies.

    Full Text Available Sequestering carbon in forest stands and using woody bioenergy are two potential ways to utilize forests in mitigating emissions of greenhouse gases (GHGs. Such forestry related strategies are, however, greatly influenced by carbon and bioenergy markets. This study investigates the impact of both carbon and woody bioenergy markets on land expectation value (LEV and rotation age of loblolly pine (Pinus taeda L. forests in the southeastern United States for two scenarios—one with thinning and no fertilization and the other with thinning and fertilization. Economic analysis was conducted using a modified Hartman model. The amount of carbon dioxide (CO2 emitted during various activities such as management of stands, harvesting, and product decay was included in the model. Sensitivity analysis was conducted with a range of carbon offset, wood for bioenergy, and forest product prices. The results showed that LEV increased in both management scenarios as the price of carbon and wood for bioenergy increased. However, the results indicated that the management scenario without fertilizer was optimal at low carbon prices and the management scenario with fertilizer was optimal at higher carbon prices for medium and low forest product prices. Carbon payments had a greater impact on LEV than prices for wood utilized for bioenergy. Also, increase in the carbon price increased the optimal rotation age, whereas, wood prices for bioenergy had little impact. The management scenario without fertilizer was found to have longer optimal rotation ages.

    Identifying regions important for spreading and mediating perturbations is crucial to assess the susceptibilities of spatio-temporal complex systems such as the Earth's climate to volcanic eruptions, extreme events or geoengineering. Here a data-driven approach is introduced based on a dimension reduction, causal reconstruction, and novel network measures based on causal effect theory that go beyond standard complex network tools by distinguishing direct from indirect pathways. Applied to a data set of atmospheric dynamics, the method identifies several strongly uplifting regions acting as major gateways of perturbations spreading in the atmosphere. Additionally, the method provides a stricter statistical approach to pathways of atmospheric teleconnections, yielding insights into the Pacific-Indian Ocean interaction relevant for monsoonal dynamics. The novel causal interaction perspective provides a complementary approach to simulations or experiments for understanding the functioning of complex spatio-temporal systems with potential applications in increasing their resilience to shocks or extreme events.

  8. On (non)elementary singularities in Liénard systems

    2017-07-01

    Liénard systems originate from ordinary differential equation (ODE) of the form x ¨+f (x )x ˙+g (x )=0 , which is well-known in (electro)mechanics and for example in radio and vacuum tube technology. The Van der Pol oscillator, which is a textbook example of a system with a limit cycle, is governed by the Liénard equation. There are two types of phase system representations in the literature: x' = y - F(x), y' = - g(x) and x' = y, y ' = -f(x)y - g(x), where F'(x) = f(x). In our case f(0)= f'(0) = g(0) = 0, g'(0) = c1, which makes (0,0) possibly nonelementary nonhyperbolic singular point of the system. Liénard showed that under some conditions on f(x) and g(x) in the system auto-oscillations arise. In this paper we consider a five-parameter family of Liénard systems with a possibly nonhyperbolic singular point. In the case of hyperbolic singularity according to the Hartman-Grobman theorem the stability of the singularity is preserved. In the case of nonhyperbolic singularity we resolve the so called center-focus problem and provide the numerical simulation of the corresponding oscillations. Recently, some generalizations of Liénard systems are studied for cyclicity, which is a part of famous Hilbert's sixteenth problem.

    Lymphangioma is a rare, benign lesion derived from a malformation of the lymphatic system, which is more frequently found in the head, neck, and axilla. However, it may be present anywhere in the body, and the diagnosis involves adults as children with some distinct clinical features among them. In pediatric patients, abdominal cystic lymphangioma occurs mostly in the mesentery presenting abdominal pain, intestinal obstruction, or, more rarely, hemorrhage. The authors report the case of a child with a short-course history of fever, abdominal pain, and constipation. The physical examination disclosed the presence of an abdominal mass and signs of peritoneal irritation. Imaging was consistent with a cystic lesion compressing the sigmoid colon and laterally displacing the remaining loops. Exploratory laparotomy was undertaken, and a sigmoidectomy, followed by Hartman's colostomy, was performed. Histological examination revealed the nature of the lesion as a cystic lymphangioma. The authors highlight the clinical features of this entity and call attention to this disease in the differential diagnosis of acute abdomen or abdominal pain, mainly in pediatric patients.

    Innovative technologies are needed to support and augment the development of various types of deformable mirrors (DM), such as Micro Electro Mechanical Systems (MEMS), segmented, bimorph and membrane types that are currently used in adaptive-optic (AO) systems. The paper discusses the results of initial studies that, could, potentially, be employed for full characterization of the dynamic behavior of adaptive optics mirrors. The experimental data were obtained from a typical bimorph mirror using both, a Shack-Hartman wavefront sensor (SHWFS) and an Imaging Laser Doppler Vibrometer (ILDV) developed exclusively by AS and T Inc. These two sensors were employed for quantitative measurement of both the spatial and temporal dynamics of the DM under broadband excitation via the piezo electric drive elements. The need to characterize the spatial and temporal dynamic response of current and future DM mirror designs is essential for optimizing their performance to a level adequate for high bandwidth AO systems, such as those employed for real-time compensation of wavefront perturbations.

    Full Text Available Robin C Wackernah,1 Matthew J Minnick,1 Peter Clapp2 1Department of Pharmacy Practice, 2Department of Pharmaceutical Sciences, School of Pharmacy, Rueckert-Hartman College for Health Professions, Regis University, Denver, CO, USA Abstract: Alcohol use disorders (AUD continue to be a concerning health issue worldwide. Harmful alcohol use leads to 2.5 million deaths annually worldwide. Multiple options exist for the management of dependence on alcohol, not all of which are approved by drug-regulating agencies. Current practice in treating AUD does not reflect the diversity of pharmacologic options that have potential to provide benefit, and guidance for clinicians is limited. Few medications are approved for treatment of AUD, and these have exhibited small and/or inconsistent effects in broad patient populations with diverse drinking patterns. The need for continued research into the treatment of this disease is evident in order to provide patients with more specific and effective options. This review describes the neurobiological mechanisms of AUD that are amenable to treatment and drug therapies that target pathophysiological conditions of AUD to reduce drinking. In addition, current literature on pharmacologic (both approved and non-approved treatment options for AUD offered in the United States and elsewhere are reviewed. The aim is to inform clinicians regarding the options for alcohol abuse treatment, keeping in mind that not all treatments are completely successful in reducing craving or heavy drinking or increasing abstinence.

  13. Extracting and compensating dispersion mismatch in ultrahigh-resolution Fourier domain OCT imaging of the retina

    We present a numerical approach to extract the dispersion mismatch in ultrahigh-resolution Fourier domain optical coherence tomography (OCT) imaging of the retina. The method draws upon an analogy with a Shack-Hartmann wavefront sensor. By exploiting mathematical similarities between the expressions for aberration in optical imaging and dispersion mismatch in spectral / Fourier domain OCT, Shack-Hartmann principles can be extended from the two-dimensional paraxial wavevector space (or the x-y plane in the spatial domain) to the one-dimensional wavenumber space (or the z-axis in the spatial domain). For OCT imaging of the retina, different retinal layers, such as the retinal nerve fiber layer (RNFL), the photoreceptor inner and outer segment junction (IS/OS), or all the retinal layers near the retinal pigment epithelium (RPE) can be used as point source beacons in the axial direction, analogous to point source beacons used in conventional two-dimensional Shack-Hartman wavefront sensors for aberration characterization. Subtleties regarding speckle phenomena in optical imaging, which affect the Shack-Hartmann wavefront sensor used in adaptive optics, also occur analogously in this application. Using this approach and carefully suppressing speckle, the dispersion mismatch in spectral / Fourier domain OCT retinal imaging can be successfully extracted numerically and used for numerical dispersion compensation to generate sharper, ultrahigh-resolution OCT images.

    Full Text Available This theoretical essay aims to study how scales are developed and through which procedures they can be considered valid and suitable for use as legitimate scientific instruments. In this perspective, this paper’s objective was to develop a protocol for constructing scales to measure attitude. The proposed protocol is configured as a logical meeting of steps based on theorists such as Allport and Hartman (1925, Thurstone (1928, Likert (1932, Campbell and Fiske (1959 and Bock (1972, which permeate all aspects of drafting scales, including construct definition, the choice of the scale itself, item preparation, scale purification, and finally its validation. At the end of the study, we present a protocol for the preparation of specific scales to measure attitude that differs from existing protocols in Churchill (1979, Rossiter (2002 and DeVellis (2003. This is in order to unite for the first time a set of promising techniques, primarily the objective delineation of the construct using focus group methodology, the proposition of an inherently dichotomous scale, scale purification via item response theory (IRT, and predictive validity.

    MHD mixed convection has been one of the center points of attraction to the heat transfer engineers for many years. In this paper, unsteady mixed convection in a T-shaped ventilated cavity filled with single phase Ferrofluid (Fe3O4-water) is analyzed thoroughly under externally applied magnetic field. The top wall of the cavity is maintained at constant cold temperature while the bottom wall of the cavity is sinusoidally heated along with adiabatic vertical walls. For pure mixed convection (Ri = 1), two different inlet velocity profiles namely uniform and Poiseuille are considered in this analysis and numerical solution is obtained for each type of inlet velocity profile, considering constant solid volume fraction of nanofluid (ϕ = 0.05) and Hartman number (Ha = 25). Qualitative analyses are presented in terms of streamline and isotherm contours and quantitative analyses are presented through Nusselt number (Nu) and average temperature (Θav) inside the cavity. It has been observed that, Nu decreases over a certain range of time and then increases very slowly. Also, Nu is a little higher in case of uniform inlet flow profile compared to Poiseuille flow profile. Interestingly, convective heat transfer rate decreases and conduction heat transfer becomes dominating, due to the externally applied magnetic field.

    The National Ignition Facility (NIF) laser will use a 192-beam multi-pass architecture capable of delivering several MJ of UV energy in temporal pulse formats varying from sub-ns square to 20 ns precisely-defined high-contrast shapes. Each beam wavefront will be subjected to effects of optics inhomogeneities, figuring errors, mounting distortions, prompt and slow thermal effects from flashlamps, driven and passive air-path turbulence, and gravity-driven deformations. A 39-actuator intra-cavity deformable mirror, controlled by data from a 77-lenslet Hartman sensor will be used to correct these wavefront aberrations and thus to assure that stringent farfield spot requirements are met. We have developed numerical models for the expected distortions, the operation of the adaptive optic system, and the anticipated effects on beam propagation, component damage, frequency conversion, and target-plane energy distribution. These models have been extensively validated against data from LLNL's Beamlet, and Amplab lasers. We review the expected beam wavefront aberrations and their potential for adverse effects on the laser performance, describe our model of the corrective system operation, and display our predictions for corrected-beam operation of the NI

    Therapies with magnetic/electromagnetic field are employed to relieve pains or, to accelerate flow of blood-particles, particularly during the surgery. In this paper, a theoretical study of the blood flow along with particles suspension through capillary was made by the electro-magneto-hydrodynamic approach. Analytical solutions to the non-dimensional blood velocity and non-dimensional particles velocity are obtained by means of the Laplace transform with respect to the time variable and the finite Hankel transform with respect to the radial coordinate. The study of thermally transfer characteristics is based on the energy equation for two-phase thermal transport of blood and particles suspension with viscous dissipation, the volumetric heat generation due to Joule heating effect and electromagnetic couple effect. The solution of the nonlinear heat transfer problem is derived by using the velocity field and the integral transform method. The influence of dimensionless system parameters like the electrokinetic width, the Hartman number, Prandtl number, the coefficient of heat generation due to Joule heating and Eckert number on the velocity and temperature fields was studied using the Mathcad software. Results are presented by graphical illustrations.

    A new hybrid optical detector is described that has many of the attributes desired for the next generation AO wavefront sensors. The detector consists of a proximity focused MCP read out by four multi-pixel application specific integrated circuit (ASIC) chips developed at CERN (â€ワMedipix2”) with individual pixels that amplify, discriminate and count input events. The detector has 512 x 512 pixels, zero readout noise (photon counting) and can be read out at 1 kHz frame rates. The Medipix2 readout chips can be electronically shuttered down to a temporal window of a few microseconds with an accuracy of 10 nanoseconds. When used in a Shack-Hartman style wavefront sensor, it should be able to centroid approximately 5000 spots using 7 x 7 pixel sub-apertures resulting in very linear, off-null error correction terms. The quantum efficiency depends on the optical photocathode chosen for the bandpass of interest. A three year development effort for this detector technology has just been funded as part of the...

    The proteolytic breakdown of the amyloid precursor protein (APP) by secretases is a complex cellular process that results in the formation of neurotoxic Aβ peptides, causative of neurodegeneration in Alzheimer's disease (AD). Processing involves monomeric and dimeric forms of APP that are transported through distinct cellular compartments where the various secretases reside. Amyloidogenic processing is also influenced by modifiers such as sorting receptor-related protein (SORLA), an inhibitor of APP breakdown and a major AD risk factor. This paper analyzed the temporal behavior of a mathematical model describing APP processing under the influence of SORLA, by performing a stability analysis of the mathematical model. We found one biochemically meaningful equilibrium point ξ. By means of linearization, Hartman-Grobman theorem, and Routh-Hurwitz test, it was shown that ξ is a locally asymptotically stable equilibrium point. The region of attraction of ξ was approximated by using the fluctuation lemma. An immediate consequence of the stability analysis of the reduced system to the temporal behavior of the solutions of the original system was also obtained. The biological implications of these results for the dynamic behavior of the activity of APP and secretases under SORLA's influence were established.

    Full Text Available This paper investigates the theoretical influence of buoyancy and thermal radiation on MHD flow over a stretching porous sheet. The model which constituted highly nonlinear governing equations is transformed using similarity solution and then solved using homotopy analysis method (HAM. The analysis is carried out up to the 5th order of approximation and the influences of different physical parameters such as Prandtl number, Grashof number, suction/injection parameter, thermal radiation parameter and heat generation/absorption coefficient and also Hartman number on dimensionless velocity, temperature and the rate of heat transfer are investigated and discussed quantitatively with the aid of graphs. Numerical results obtained are compared with the previous results published in the literature and are found to be in good agreement. It was found that when the buoyancy parameter and the fluid velocity increase, the thermal boundary layer decreases. In case of the thermal radiation, increasing the thermal radiation parameter produces significant increases in the thermal conditions of the fluid temperature which cause more fluid in the boundary layer due to buoyancy effect, causing the velocity in the fluid to increase. The hydrodynamic boundary layer and thermal boundary layer thickness increase as a result of increase in radiation.

  2. Synthetic alienation of microbial organisms by using genetic code engineering: Why and how?

    The main goal of synthetic biology (SB) is the creation of biodiversity applicable for biotechnological needs, while xenobiology (XB) aims to expand the framework of natural chemistries with the non-natural building blocks in living cells to accomplish artificial biodiversity. Protein and proteome engineering, which overcome limitation of the canonical amino acid repertoire of 20 (+2) prescribed by the genetic code by using non-canonic amino acids (ncAAs), is one of the main focuses of XB research. Ideally, estranging the genetic code from its current form via systematic introduction of ncAAs should enable the development of bio-containment mechanisms in synthetic cells potentially endowing them with a "genetic firewall" i.e. orthogonality which prevents genetic information transfer to natural systems. Despite rapid progress over the past two decades, it is not yet possible to completely alienate an organism that would use and maintain different genetic code associations permanently. In order to engineer robust bio-contained life forms, the chemical logic behind the amino acid repertoire establishment should be considered. Starting from recent proposal of Hartman and Smith about the genetic code establishment in the RNA world, here the authors mapped possible biotechnological invasion points for engineering of bio-contained synthetic cells equipped with non-canonical functionalities.

    A new species of Sphaerodoridium Lützen, 1961 (Polychaeta: Sphaerodoridae) collected off Iceland during the BIOICE programme is described. Sphaerodoridium guerritai sp. nov. is mostly present in waters around the northern half of Iceland, and seems to be common in soft bottoms at depths of 49-1253 m. It is mainly characterized by having macrotubercles which are provided with a long stalk which bears 1-3 small papillae; this seems an unique feature in Sphaerodoridium and the closely related genus Clavodorum Hartman and Fauchald, 1971. Furthermore, the new species is also characterized by having one transversal row of 11-12 dorsal macrotubercles per chaetiger in midbody; 10-16 spherical papillae in front of each row of macrotubercles, somewhat arranged in a dorsal zig-zag; 10-18 ventral papillae per chaetiger arranged following a non-random pattern: two transversal rows on parapodial areas and one on interparapodial area, of usually 4, 6 and 5 papillae respectively. Short paired tubular structures with distal opening were found on the ventrum of most chaetigers and are interpreted as nephridial papillae and nephridiopores, respectively. Females show special ventral structures between chaetigers 9-10 which may represent genital openings as suggested for other sphaerodorids; males do not show any apparent copulatory structures. A comprehensive table comparing some diagnostic features regarding macrotubercles and body papillae of all known species of Sphaerodoridium and Clavodorum is provided. 

  4. Angle Dependence of the Orbital Magnetoresistance in Bismuth

    Full Text Available We present an extensive study of angle-dependent transverse magnetoresistance in bismuth, with a magnetic field perpendicular to the applied electric current and rotating in three distinct crystallographic planes. The observed angular oscillations are confronted with the expectations of semiclassic transport theory for a multivalley system with anisotropic mobility and the agreement allows us to quantify the components of the mobility tensor for both electrons and holes. A quadratic temperature dependence is resolved. As Hartman argued long ago, this indicates that inelastic resistivity in bismuth is dominated by carrier-carrier scattering. At low temperature and high magnetic field, the threefold symmetry of the lattice is suddenly lost. Specifically, a 2π/3 rotation of magnetic field around the trigonal axis modifies the amplitude of the magnetoresistance below a field-dependent temperature. By following the evolution of this anomaly as a function of temperature and magnetic field, we map the boundary in the (field, temperature plane separating two electronic states. In the less symmetric state, confined to low temperature and high magnetic field, the three Dirac valleys cease to be rotationally invariant. We discuss the possible origins of this spontaneous valley polarization, including a valley-nematic scenario.

    Colorectal cancer usually present with known symptoms while there are less common manifestation including abscess formation which can be intra or extra peritoneal. A 60-year-old Caucasian male with a history of RLQ abdominal pain, nausea, vomiting and anorexia from 15 days ago referred to surgery ward. Ultrasound showed a hypoachoic lesion with diameters 50 mm × 70 mm in RLQ of abdomen and a round echogenic area in right lobe of liver with diameter 15 mm. The findings were revealed an abscess located in right iliac fossa then local drainage of abscess was performed. Four days later the patient was re-admitted because of severe abdominal distention and lack of bowel movement. Laparoscopy was performed before proceeding with further examinations, due to the poor general condition of the patient. The sigmoid was adherent into the abdominal wall and mild intestinal loop distention and apple-core view was observed during operation. Can-cer of sigmoid complicated by a right iliac fossa abscess was diagnosed and Hartman colestomy was undertaken. At the last follow-up examination 3 months after operation, the patient was in good health with no clinical evidence of recurrence.

  7. MHD peristaltic transport of spherical and cylindrical magneto-nanoparticles suspended in water

    2015-07-01

    Full Text Available Advancements in the biomedical engineering have enhanced the usage of magnto-nanoparticles in improving the precision and efficiency of the magneto-drug delivery systems. Such systems make use of the externally applied magnetic fields to direct the drug towards a specific target in the human body. Peristalsis of magneto-nanofluids is of significant importance in such considerations. Hence peristaltic transport of Fe3O4-water nanofluid through a two-dimensional symmetric channel is analyzed in the presence of an externally applied constant magnetic field. Hamilton-Crosser’s model of the thermal conductivity is utilized in the problem development. The nanofluid saturates a non-uniform porous medium in which the porosity of the porous medium varies with the distance from the channel walls. Analysis is performed for the spherical and the cylindrical nanoparticles. Resulting system of equations is numerically solved. Impacts of sundry parameters on the axial velocity, temperature, pressure gradient and heat transfer rate at the boundary are examined. Comparison between the results for spherical and cylindrical nanoparticles is also presented. Results show that the nanoparticles volume fraction and the Hartman number have increasing effect on the pressure gradient throughout the peristaltic tract. Effective heat transfer rate at the boundary tends to enhance with an increase in the nanoparticles volume fraction. Use of spherical nanoparticles results in a higher value of axial velocity and the temperature at the center of channel when compared with the case of cylindrical nanoparticles.

  8. Amplitude and phase beam characterization using a two-dimensional wavefront sensor

    1996-09-01

    We have developed a two-dimensional Shack-Hartman wavefront sensor that uses binary optic lenslet arrays to directly measure the wavefront slope (phase gradient) and amplitude of the laser beam. This sensor uses an array of lenslets that dissects the beam into a number of samples. The focal spot location of each of these lenslets (measured by a CCD camera) is related to the incoming wavefront slope over the lenslet. By integrating these measurements over the laser aperture, the wavefront or phase distribution can be determined. Since the power focused by each lenslet is also easily determined, this allows a complete measurement of the intensity and phase distribution of the laser beam. Furthermore, all the information is obtained in a single measurement. Knowing the complete scalar field of the beam allows the detailed prediction of the actual beam`s characteristics along its propagation path. In particular, the space- beamwidth product M{sup 2}, can be obtained in a single measurement. The intensity and phase information can be used in concert with information about other elements in the optical train to predict the beam size, shape, phase and other characteristics anywhere in the optical train. We present preliminary measurements of an Ar{sup +} laser beam and associated M{sup 2} calculations.

    Full Text Available Cloacogenic carcinoma (CC, basaloid carcinoma generally occurs around the dentate line, rarely it can arise from the other sides of the colon. There are only 5 cases of CC located outside the anal canal in the literature. The first occurrence of a CC presents as intraabdominal abscess. We describe a 23-year-old male patient who was admitted with fever and severe abdominal pain. Computed tomography imaging showed diffuse wall thickening about 10–11 cm above the rectosigmoid junction, intraabdominal abscess and a soft tissue lession covering the pelvis with a size of 8 × 8.5 cm including cystic necrotic areas. We performed Hartman procedure since the mass was nonresectable. Histopathological examination showed CC. In total, three times radiotherapy and a concurrent three-drug regimen of irinotecan, fluorouracil and folinic acid chemotherapy were administered for 6 weeks. As a result, the patient was lost because of multiple organ dysfunction syndrome that developed 3 months after radio-chemotherapy.

    Transpositions are large-scale mutational events that occur when a block of genes moves from a region of a chromosome to another region within the same chromosome. The transposition distance problem is the minimum number of transpositions required to transform one genome into another. Recently, Bulteau et al. [Bulteau L, Fertin G, Rusu U, Automata, Languages and Programming, Vol. 6755 of Lecture Notes in Computer Science, pp. 654-665, Springer Berlin, Heidelberg, 2011] proved that finding the transposition distance is a NP-Hard problem. Some approximation algorithm for this problem have been presented to date [Bafna V, Pevzner PA, SIAM J Discr Math11(2):224-240, 1998; Elias I, Hartman T, IEEE/ACM Trans Comput Biol Bioinform3(4):369-379, 2006; Mira CVG, Dias Z, Santos HP, Pinto GA, Walter ME, Proc 3rd Brazilian Symp Bioinformatics (BSB'2008), pp. 115-126, Santo André, Brazil, 2008; Walter MEMT, Dias Z, Meidanis J, Proc String Processing and Information Retrieval (SPIRE'2000), pp. 199-208, Coruña, Spain, 2000]. Here we focus on developing heuristics to provide an improved approximated solution. Our approach outperforms other algorithms on small sized permutations. We also show that our algorithm keeps the good performance on longer permutations.

    In order to obtain a clear image of the retina of model eye, an adaptive optics system used to correct the wave-front error is introduced in this paper. The spatial light modulator that we use here is a liquid crystal on a silicon device instead of a conversional deformable mirror. A paper with carbon granule is used to simulate the retina of human eye. The pupil size of the model eye is adjustable (3-7 mm). A Shack-Hartman wave-front sensor is used to detect the wave-front aberration. With this construction, a value of peak-to-valley is achieved to be 0.086 λ, where A is wavelength.The modulation transfer functions before and after corrections are compared. And the resolution of this system after correction (691p/m) is very close to the diffraction limit resolution. The carbon granule on the white paper which has a size of 4.7μm is seen clearly. The size of the retina cell is between 4 and 10 μm. So this system has an ability to image the human eye's retina.

    This paper addresses the peristaltic flow in curved channel with combined heat/mass transfer and convective effects. The channel walls are flexible. An imposed magnetic field is applied in radial direction to increase the wave amplitude (used in ECG for synchronization purposes). The pseudoplastic fluid comprising shear-thinning/shear thickening effects has been used in mathematical modeling. Small Reynolds number assumption is employed to neglect inertial effects. Half channel-width to wavelength ratio is small enough for the pressure to be considered uniform over the cross-section. The graphical results obtained are compared with planar channel. Results show the non-symmetric behavior of sundry parameters in contrary to the planar case. Additionally more clear results are seen when the curved channel is approached. - Highlights: • The behavior of curvature parameter k on velocity is not symmetric. • Temperature is decreasing function of Biot number Bi. • Hartman number has similar qualitative effects on both velocity and temperature. • Behavior of concentration is opposite to that of temperature in a qualitative sense. • Bolus size via curvature parameter has opposite effect near the upper and lower channel walls.

    Abstract Diplocirrus Haase, 1915, includes flabelligerids having cylindrical to club-shaped bodies, with cirriform papillae, multiarticulate chaetae in both parapodial rami, 8 branchial filaments of two types (thick and rarely lamellate, or cirriform), gonopodial lobes in chaetigers 5 or 6, or multiple gonopores along some anterior chaetigers. Bradiella Rullier, 1965, has included only the type species: Bradiella branchiata Rullier, 1965, described from Eastern Australia. The original description has been overlooked and it lacked enough details on branchial and chaetal features. Diversibranchius Buzhinskaja, 1993, with Diplocirrus nicolaji Buzhinskaja, 1994, as the type species, was introduced for a similar species from the Japan Sea. These two monotypic genera share the same morphologic features with Diplocirrus, and are herein regarded as its junior synonyms. As herein redefined, Diplocirrus includes, besides its type species, Diplocirrus glaucus (Malmgren, 1867)from Scandinavia : Diplocirrus branchiatus (Rullier, 1965), comb. n. from Queensland, Australia, Diplocirrus capensis Day, 1961 from South Africa, Diplocirrus erythroporus Gallardo, 1968 from Vietnam, Diplocirrus hirsutus (Hansen, 1882) from Arctic and subarctic regions, Diplocirrus incognitus Darbyshire & Mackie, 2009 from South Africa, Diplocirrus kudenovi sp. n. from off Western Mexico, Diplocirrus longisetosus (von Marenzeller, 1890) restricted to the Bering Sea, Diplocirrus micans Fauchald, 1972 from deep water off Oregon and Western Mexico, Diplocirrus nicolaji (Buzhinskaja, 1994), comb. n. from the Japan Sea, Diplocirrus normani (McIntosh, 1908), comb. n. from Scandinavia, Diplocirrus octobranchus (Hartman, 1965), comb. n. from off New England, and Diplocirrus stopbowitzi Darbyshire & Mackie, 2009 from the Irish Sea.

  16. Entanglement, tensor networks and black hole horizons

    Molina-Vilaplana, J.; Prior, J.

    2014-11-01

    We elaborate on a previous proposal by Hartman and Maldacena on a tensor network which accounts for the scaling of the entanglement entropy in a system at a finite temperature. In this construction, the ordinary entanglement renormalization flow given by the class of tensor networks known as the Multi Scale Entanglement Renormalization Ansatz (MERA), is supplemented by an additional entanglement structure at the length scale fixed by the temperature. The network comprises two copies of a MERA circuit with a fixed number of layers and a pure matrix product state which joins both copies by entangling the infrared degrees of freedom of both MERA networks. The entanglement distribution within this bridge state defines reduced density operators on both sides which cause analogous effects to the presence of a black hole horizon when computing the entanglement entropy at finite temperature in the AdS/CFT correspondence. The entanglement and correlations during the thermalization process of a system after a quantum quench are also analyzed. To this end, a full tensor network representation of the action of local unitary operations on the bridge state is proposed. This amounts to a tensor network which grows in size by adding succesive layers of bridge states. Finally, we discuss on the holographic interpretation of the tensor network through a notion of distance within the network which emerges from its entanglement distribution.

    Pedoto, J P; Hartman, B W

    1992-12-01

    This study has empirically assessed whether artistic orientation and avoidance are good predictors of chronic career indecision for college-attending adult children and grandchildren of alcoholics. The sample consisted of 143 freshman and sophomore introductory psychology students attending a county college in the northeast. Osipow's Career Decision Scale total scores of artistically oriented children and grandchildren of alcoholics were not significantly higher than scores of those who were not artistic. As predicted, the Career Decision Scale total scores of avoidant subjects were significantly higher than those of nonavoidant subjects. As expected in both instances, no differences were found between artistic subjects and nonartistic subjects or between the avoidant and nonavoidant subjects. The findings suggest (1) that the artistic career-undecided children of alcoholics observed by Schumrum and Hartman in 1988 were, in fact, members of a broader avoidant group and (2) that the relationship between career indecision and avoidant personality style does vary according to family status of whether subjects are adult children and grandchildren of alcoholics.

    KAPAO (KAPAO A Pomona Adaptive Optics instrument) is a dual-band natural guide star adaptive optics system designed to measure and remove atmospheric aberration over UV-NIR wavelengths from Pomona College’s telescope atop Table Mountain. We present here, the final optical system, KAPAO Prime, designed in Zemax Optical Design Software that uses custom off-axis paraboloid mirrors (OAPs) to manipulate light appropriately for a Shack-Hartman wavefront sensor, deformable mirror, and science cameras. KAPAO Prime is characterized by diffraction limited imaging over the full 81” field of view of our optical camera at f/33 as well as over the smaller field of view of our NIR camera at f/50. In Zemax, tolerances of 1% on OAP focal length and off-axis distance were shown to contribute an additional 4 nm of wavefront error (98% confidence) over the field of view of our optical camera; the contribution from surface irregularity was determined analytically to be 40nm for OAPs specified to λ/10 surface irregularity (632.8nm). Modeling of the temperature deformation of the breadboard in SolidWorks revealed 70 micron contractions along the edges of the board for a decrease of 75°F when applied to OAP positions such displacements from the optimal layout are predicted to contribute an additional 20 nanometers of wavefront error. Flexure modeling of the breadboard due to gravity is on-going. We hope to begin alignment and testing of KAPAO Prime in Q1 2013.

On their success depends the ability of the accelerator to function correctly at nominal energy. No mean challenge, considering it comes on top of the tenfold reduction already achieved since 2009.   The graph plots the rate of LHC beam dumps due to single-event effects against beam luminosity. An indication of the challenge that faces the R2E project teams during LS1! The origins of the project known as R2E (Radiation to Electronics) go back to 2007, when the CNGS (CERN Neutrinos to Gran Sasso) experiment was being commissioned. "Right from the outset, some CNGS control systems were causing problems. They would regularly break down in operations with beam," recalls Markus Brugger, head of the R2E project. "Even though the beam intensity was very low, we began to suspect that radiati...

However, parents of elite athletes may be critical and demanding. Moreover, there is evidence that girls report more favorable perceived parenting styles compared with boys. The aim of the present study was to investigate perceived parenting styles among female and male adolescent elite athletes and controls. We sampled 258 adolescent elite athletes (139 females, 119 males and 176 controls (139 females, 37 males. Participants completed a questionnaire to assess perceived parenting styles (support, commendation, reproach, restriction, inconsistency. Results showed that parenting styles did not differ between athletes and controls, except for restriction, for which athletes reported lower levels. Female adolescents had higher scores for positive and lower scores for negative perceived parenting styles.Keywords: parenting style, gender, elite athletes, controls

    This study was performed to evaluate the accuracy of a commercial treatment planning system (TPS), in optimising proton pencil beam dose distributions for small targets of different sizes (5-30 mm side) located at increasing depths in water. The TPS analytical algorithm was benchmarked against experimental data and the FLUKA Monte Carlo (MC) code, previously validated for the selected beam-line. We tested the Siemens syngo® TPS plan optimisation module for water cubes fixing the configurable parameters at clinical standards, with homogeneous target coverage to a 2 Gy (RBE) dose prescription as unique goal. Plans were delivered and the dose at each volume centre was measured in water with a calibrated PTW Advanced Markus® chamber. An EBT3® film was also positioned at the phantom entrance window for the acquisition of 2D dose maps. Discrepancies between TPS calculated and MC simulated values were mainly due to the different lateral spread modeling and resulted in being related to the field-to-spot size ratio. The accuracy of the TPS was proved to be clinically acceptable in all cases but very small and shallow volumes. In this contest, the use of MC to validate TPS results proved to be a reliable procedure for pre-treatment plan verification.

    Full Text Available In order to obtain reliable information on yield and root quality of new sugar beet hybrids, the micro varietal trials were set up on the experimental field of the Faculty of Agriculture at the University of Zagreb in the period from 2010 to 2013. The study included a total of 51 sugar beet hybrids owned by five breeding companies present in the Croatian market. There were significant differences among investigated hybrids in root and sugar yield and sugar content in the roots in all years of research, except in the dry 2011. However, a large number of hybrids achieved statistically equal values because the differences were within the statistical tolerance. In 2010, the highest root yield (107.5 t/ha and the highest technological sugar yield (13.5 t/ha were achieved by the hybrid Elvis. That year, the largest sugar content (15.68% was achieved by the hybrid Markus. In 2012, the highest root yield (86.4 t/ha, and the highest sugar yield (12.0 t/ha were achieved by the hybrid Serenada KWS. The largest root sugar content (17.37% was achieved by the hybrid Denisa KWS. In 2013, the highest root yield (90.2 t/ha and the highest sugar yield (10.8 t/ha were achieved by the hybrid Terranova KWS. That year, the largest sugar content in root (15.23% was achieved by the hybrid Pharaon.

  6. Estimating the impact of enterprise resource planning project management decisions on post-implementation maintenance costs: a case study using simulation modelling

    Fryling, Meg

    2010-11-01

    Organisations often make implementation decisions with little consideration for the maintenance phase of an enterprise resource planning (ERP) system, resulting in significant recurring maintenance costs. Poor cost estimations are likely related to the lack of an appropriate framework for enterprise-wide pre-packaged software maintenance, which requires an ongoing relationship with the software vendor (Markus, M.L., Tanis, C., and Fenema, P.C., 2000. Multisite ERP implementation. CACM, 43 (4), 42-46). The end result is that critical project decisions are made with little empirical data, resulting in substantial long-term cost impacts. The product of this research is a formal dynamic simulation model that enables theory testing, scenario exploration and policy analysis. The simulation model ERPMAINT1 was developed by combining and extending existing frameworks in several research domains, and by incorporating quantitative and qualitative case study data. The ERPMAINT1 model evaluates tradeoffs between different ERP project management decisions and their impact on post-implementation total cost of ownership (TCO). Through model simulations a variety of dynamic insights were revealed that could assist ERP project managers. Major findings from the simulation show that upfront investments in mentoring and system exposure translate to long-term cost savings. The findings also indicate that in addition to customisations, add-ons have a significant impact on TCO.

    Full Text Available Since 2007 the university library at the Medical University Vienna runs a provenance research project. Books, stolen between 1938 and 1945, were acquired by at that time discrete libraries at institutions and clinics of the former medical faculty at Vienna University. A systematic survey of the now centralised book collection should bring to light these misgotten book acquisitions. Aim of the project is to document such cases and to restitute books to their lawful owners or their legal successors. Until Novemver 2008 about 80,000 volumes were scrutinised directly at the shelves by so-called autopsy. So far about 200 definitely stolen books and approximately 1800 suspicious books were dedected. This paper describes the initial position, method and hitherto existing results of the provenance research project. Ten cases of such book theft, recorded in the now centralised collection of the university library of the Medical University Vienna (former medical faculty, should depict victims of book expropiation during nazi regime.

    Perforated thermoplastic masks are used to provide patients immobilization. This procedure inserts a material in the path of the radiation beam, that attenuates and modifies the beam fluence and flatness. The present study evaluates the increase in skin dose as a result of using thermoplastic masks. Relative doses were measured on the surface of a solid water phantom, in the presence and absence of masks. These masks were stretched according to deformation patterns observed in clinical routine. The measurements were obtained with a plane-parallel chamber (Markus type 23343) and radiochromic film (EBT Gafchromic) for 6MV X-rays from a linear accelerator, and for a radiation beam from a cobalt therapy unit. The results showed that thermoplastic masks, whose thickness varied between 2 and 3 mm, increased the dose on the surface by a factor of 3. Due to the variations in the skin dose distribution, clinical procedures were suggested to minimize radiobiological damages in subcutaneous tissue, and to keep the skin sparing effect. (author)

The findings indicated that PA was directly and indirectly associated with SE. BMI predicted SE neither directly nor indirectly, but was directly associated with PPF and both directly and indirectly with BI. Furthermore, PPF was directly related to BI and SE, and a direct association was found between BI and SE. The pattern of results suggests that among a sample of adults, PA is directly and indirectly associated with SE, PPF, and BI, but not with BMI. PA, PPF, and BI appear to play an important role in SE. Accordingly, regular PA should be promoted, in particular, among adults reporting lower SE. Keywords: physical activity, self-esteem, physical fitness, body image, adults

Several case studies have reported neurological and psychiatric complications of N2O use. To date, however, there has not been a study using standardized diagnostic procedures to assess psychiatric comorbidities in a patient consuming N2O. Here, we report about a 35-year-old male with magnetic resonance imaging confirmed subacute myelopathy induced by N2O consumption, who suffered from comorbid cannabinoid and nicotine dependence as well as abuse of amphetamines, cocaine, lysergic acid diethylamide, and ketamine. Additionally, there was evidence of a preceding transient psychotic and depressive episode induced by synthetic cannabinoid abuse. In summary, this case raises awareness of an important mechanism of neural toxicity, with which physicians working in the field of ­substance-related disorders should be familiar. In fact, excluding N2O toxicity in patients with recognized substance-related disorders and new neurological deficits is compulsory, as untreated for months the damage to the nervous system is at risk of becoming irreversible.

    Full Text Available M Andrea Markus, Brian J MorrisSchool of Medical Sciences and Bosch Institute, The University of Sydney, Sydney, NSW, AustraliaAbstract: Resveratrol is a potent member of the class of natural, plant-derived chemicals known as polyphenols. These help explain in part why a diet high in fruit and vegetables confers health benefits and are associated with reduced risk of common complex conditions such as cardiovascular disease, cancer, diabetes, and Alzheimer’s disease. We present the latest molecular findings that account for the beneficial actions of resveratrol. The intracellular pathways activated are crucial for anti-oxidant defence, regulation of the cell cycle, mitochondrial energy production, vascular tone, oncogene suppression, and many other phenomena which if unchecked lead to morbidity and mortality from onset and progression of these various diseases. While a healthy diet and lifestyle is strongly recommended in prevention of such conditions, the future bodes well for the use of resveratrol and analogues of higher potency than the natural form for treatment of diseases that afflict humans, particularly as they age.Keywords: resveratrol, longevity, SIRT, wine, aging, cancer

  19. An abstract approach to some spectral problems of direct sum differential operators

    Directory of Open Access Journals (Sweden)

    Maksim S. Sokolov

    2003-07-01

    Full Text Available In this paper, we study the common spectral properties of abstract self-adjoint direct sum operators, considered in a direct sum Hilbert space. Applications of such operators arise in the modelling of processes of multi-particle quantum mechanics, quantum field theory and, specifically, in multi-interval boundary problems of differential equations. We show that a direct sum operator does not depend in a straightforward manner on the separate operators involved. That is, on having a set of self-adjoint operators giving a direct sum operator, we show how the spectral representation for this operator depends on the spectral representations for the individual operators (the coordinate operators involved in forming this sum operator. In particular it is shown that this problem is not immediately solved by taking a direct sum of the spectral properties of the coordinate operators. Primarily, these results are to be applied to operators generated by a multi-interval quasi-differential system studied, in the earlier works of Ashurov, Everitt, Gesztezy, Kirsch, Markus and Zettl. The abstract approach in this paper indicates the need for further development of spectral theory for direct sum differential operators.

  1. Determination of relative ion chamber calibration coefficients from depth-ionization measurements in clinical electron beams

    2014-10-01

    A method is presented to obtain ion chamber calibration coefficients relative to secondary standard reference chambers in electron beams using depth-ionization measurements. Results are obtained as a function of depth and average electron energy at depth in 4, 8, 12 and 18 MeV electron beams from the NRC Elekta Precise linac. The PTW Roos, Scanditronix NACP-02, PTW Advanced Markus and NE 2571 ion chambers are investigated. The challenges and limitations of the method are discussed. The proposed method produces useful data at shallow depths. At depths past the reference depth, small shifts in positioning or drifts in the incident beam energy affect the results, thereby providing a built-in test of incident electron energy drifts and/or chamber set-up. Polarity corrections for ion chambers as a function of average electron energy at depth agree with literature data. The proposed method produces results consistent with those obtained using the conventional calibration procedure while gaining much more information about the behavior of the ion chamber with similar data acquisition time. Measurement uncertainties in calibration coefficients obtained with this method are estimated to be less than 0.5%. These results open up the possibility of using depth-ionization measurements to yield chamber ratios which may be suitable for primary standards-level dissemination.

    Small circular beams of synchrotron radiation (0.1 mm and 0.4 mm in diameter) were used to irradiate ionization chambers of the types commonly used in radiotherapy. By scanning the chamber through the beam and measuring the ionization current, a spatial map of the dosimetric response of the chamber was recorded. The technique is able to distinguish contributions to the large-field ionization current from the chamber walls, central electrode and chamber stem. Scans were recorded for the NE 2571 Farmer chamber, the PTW 30013, IBA FC65-G Farmer-type chambers, the NE 2611A and IBA CC13 thimble chambers, the PTW 31006 and 31014 pinpoint chambers, the PTW Roos and Advanced Markus plane-parallel chambers, and the PTW 23342 thin-window soft x-ray chamber. In all cases, large contributions to the response arise from areas where the incident beam grazes the cavity surfaces. Quantitative as well as qualitative information about the relative chamber response was extracted from the maps, including the relative contribution of the central electrode. Line scans using monochromatic beams show the effect of the photon energy on the chamber response. For Farmer-type chambers, a simple Monte Carlo model was in good agreement with the measured response.

    Full Text Available After the famous exhibition “Copier créer” curated by Jean Pierre Cuzin in the “Musée du Louvre” in 1993, the practice of drawing art has acquired a renovated interest. This exhibition revised the theoretical concepts introduced by Bober and others in the second half of the XXth century and increased the value of the contribution of drawing in the study of art history instead of the idea of copying. An important catalog and essay by Haverkamp, Begemann and Login, titled “Creative copies”, appeared in 1988 and contained the best examples of the main collections. The last but not least important consequence was the collaboration between international museums, using their own spaces, with contemporary artists. The hermeneutic drawings and paintings by Markus Lüpertz in the Munich Glyptotheck and the exhibition of Giacometti’s drawings shown in the IVAM in 2000 are two excellent examples of the European relevance in this field. I want to analyze here twenty years of drawing done in different museums and institutions around the world and its close relationship with the process of recovering our historical memory by using visual art.

    2015-01-01

    The aim of this volume is to provide an extensive account of the most recent advances in statistics for discretely observed Lévy processes. These days, statistics for stochastic processes is a lively topic, driven by the needs of various fields of application, such as finance, the biosciences, and telecommunication. The three chapters of this volume are completely dedicated to the estimation of Lévy processes, and are written by experts in the field. The first chapter by Denis Belomestny and Markus Reiß treats the low frequency situation, and estimation methods are based on the empirical characteristic function. The second chapter by Fabienne Comte and Valery Genon-Catalon is dedicated to non-parametric estimation mainly covering the high-frequency data case. A distinctive feature of this part is the construction of adaptive estimators, based on deconvolution or projection or kernel methods. The last chapter by Hiroki Masuda considers the parametric situation. The chapters cover the main aspects of the est...

    This study was performed to evaluate the accuracy of a commercial treatment planning system (TPS), in optimising proton pencil beam dose distributions for small targets of different sizes (5–30 mm side) located at increasing depths in water. The TPS analytical algorithm was benchmarked against experimental data and the FLUKA Monte Carlo (MC) code, previously validated for the selected beam-line. We tested the Siemens syngo® TPS plan optimisation module for water cubes fixing the configurable parameters at clinical standards, with homogeneous target coverage to a 2 Gy (RBE) dose prescription as unique goal. Plans were delivered and the dose at each volume centre was measured in water with a calibrated PTW Advanced Markus® chamber. An EBT3® film was also positioned at the phantom entrance window for the acquisition of 2D dose maps. Discrepancies between TPS calculated and MC simulated values were mainly due to the different lateral spread modeling and resulted in being related to the field-to-spot size r...

  7. Business Value Creation from IT Investments: towards a process theory of IT governance

    2005-05-01

    Full Text Available The history of Information Systems (IS as a discipline has been accompanied by vigorous debate on how, and indeed whether, IT investments contribute to improving organisational performance and hence in delivering value to the organisation. A number of models have been put forward to describe the relationship between IT expenditure and business value. This paper considers one such model, the process model of Soh and Markus (1995, and although this model has many attractive features, it is perhaps deficient in the way in which it links IT investment proposals back to business objectives, drivers and requirements. A modification of this model is thus proposed, and empirically assessed through qualitative interviews with CIOs in large organisations to understand the practises and processes by which they assert that business value is achieved through IT investments. The modified model was largely supported by the empirical study, but an additional factor, that of the need for and importance of sound IT governance processes and procedures to be in place if business value is to be derived form IT expenditure.

  8. Cultural values and performance appraisal: assessing the effects of rater self-construal on performance ratings.

    2013-01-01

    Much of the prior research investigating the influence of cultural values on performance ratings has focused either on conducting cross-national comparisons among raters or using cultural level individualism/collectivism scales to measure the effects of cultural values on performance ratings. Recent research has shown that there is considerable within country variation in cultural values, i.e. people in one country can be more individualistic or collectivistic in nature. Taking the latter perspective, the present study used Markus and Kitayama's (1991) conceptualization of independent and interdependent self-construals as measures of individual variations in cultural values to investigate within culture variations in performance ratings. Results suggest that rater self-construal has a significant influence on overall performance evaluations; specifically, raters with a highly interdependent self-construal tend to show a preference for interdependent ratees, whereas raters high on independent self-construal do not show a preference for specific type of ratees when making overall performance evaluations. Although rater self-construal significantly influenced overall performance evaluations, no such effects were observed for specific dimension ratings. Implications of these results for performance appraisal research and practice are discussed.

In some cases, no neurological deficits are present, even after penetrating trauma. These patients have a greater risk of suffering from secondary injuries due to secondary infections, brain edema, and hematomas. We present a case report which illustrates that brain injuries that do not induce neurological deficits can still result in a fatal clinical course and death, with medicolegal consequences.Clinical presentation: A 19-year-old patient was admitted to hospital suffering from a head injury due to an assault. He reported that he was attacked from behind. Medical examination showed no neurological deficits, and only a small occipital wound. Neuroimaging of the cranium revealed that a knife blade was penetrating the cranial bone and touching the superior sagittal sinus.Intervention: After removing the foreign body, magnetic resonance imaging showed that the superior sagittal sinus remained open.Conclusion: We want to stress that possible problems can arise due to the retention of objects in the cranium, while also highlighting the risk of superficial clinical examination.Keywords: head trauma, guidelines, retained object, neuroimaging

    Calculation of ab initio potential energy surfaces for molecules to high accuracy is only manageable for a handful of molecular systems. Among them is the simplest polyatomic molecule, the H_3^+ cation. In order to achieve a high degree of accuracy (transitions of H_3^+ with MHz-level precision, all of which have arisen from low lying rotational levels. Here we present new measurements of rovibrational transitions arising from higher rotational and vibrational levels. These transitions not only allow for probing higher energies on the potential energy surface, but through the use of combination differences, will ultimately lead to prediction of the "forbidden" rotational transitions with MHz-level accuracy.

Como opción se plantea ampliar la perspectiva, partir del “eje del florecimiento humano” (donde el ser humano se encuentra completo y “recortar” su contenido para arribar al del eje del nivel de vida. En el eje del florecimiento humano es donde puede desarrollarse la reflexión sobre las “necesidades y capacidades humanas” que, a su vez, debe fundamentarse en una discusión sistemática sobre la “esencia humana”.

    Metabolite identification from tandem mass spectra is an important problem in metabolomics, underpinning subsequent metabolic modelling and network analysis. Yet, currently this task requires matching the observed spectrum against a database of reference spectra originating from similar equipment and closely matching operating parameters, a condition that is rarely satisfied in public repositories. Furthermore, the computational support for identification of molecules not present in reference databases is lacking. Recent efforts in assembling large public mass spectral databases such as MassBank have opened the door for the development of a new genre of metabolite identification methods. We introduce a novel framework for prediction of molecular characteristics and identification of metabolites from tandem mass spectra using machine learning with the support vector machine. Our approach is to first predict a large set of molecular properties of the unknown metabolite from salient tandem mass spectral signals, and in the second step to use the predicted properties for matching against large molecule databases, such as PubChem. We demonstrate that several molecular properties can be predicted to high accuracy and that they are useful in de novo metabolite identification, where the reference database does not contain any spectra of the same molecule.

    Cerebrospinal fluid (CSF) circulation and turnover provides a sink for the elimination of solutes from the brain interstitium, serving an important homeostatic role for the function of the central nervous system. Disruption of normal CSF circulation and turnover is believed to contribute to the development of many diseases, including neurodegenerative conditions such as Alzheimer's disease, ischemic and traumatic brain injury, and neuroinflammatory conditions such as multiple sclerosis. Recent insights into CSF biology suggesting that CSF and interstitial fluid exchange along a brain-wide network of perivascular spaces termed the 'glymphatic' system suggest that CSF circulation may interact intimately with glial and vascular function to regulate basic aspects of brain function. Dysfunction within this glial vascular network, which is a feature of the aging and injured brain, is a potentially critical link between brain injury, neuroinflammation and the development of chronic neurodegeneration. Ongoing research within this field may provide a powerful new framework for understanding the common links between neurodegenerative, neurovascular and neuroinflammatory disease, in addition to providing potentially novel therapeutic targets for these conditions.

Attitudes and beliefs are bound to change over time and are affected by socio-cultural changes, particularly in areas such as power relationships, the image of women and that of identity construction. The first coursebook analyses in terms of women’s representations and sexist attitudes date back to the 70s and the 80s (e.g. Hartman, Judd 1978; Stern 1976; Porreca 1984; Schmitz 1975, 1984 and have been greatly influenced by language and gender studies (e.g. Sunderland 1992, 1994, 2000; Sunderland, Litosseliti 2002; Cameron 2005. This paper is aimed at presenting the results of a study on how women and their voices have been portrayed in ELT coursebooks addressed to Italian students over time. The analysis carried out in a diachronic perspective, have specifically focussed upon textbooks published between the 1950s and the beginning of the 80s in order to represent different historical perspectives. The proposed stretch in time to the 80s is aimed at investigating the most relevant shifts occurring in ELT coursebooks in the 70s as a consequence of changes in society and the influence of gender studies. The categories used to analyse the ELT materials have been: the representation (as well as the omission of women and their roles in texts and illustrations; the language used to refer to women and its role in maintaining, diminishing or reinforcing sexist values. Despite a correspondence between gender representations and ongoing changes in society, the textbooks examined appear to represent more traditional than innovative views on women.

    This work compares the surface modifications induced by the immersion in solutions that simulate inflammatory conditions of pure titanium (cpTi) and medical grade stainless steel (SS). The inflammatory conditions were simulated using a mixture of Hartman solution and 50 mM of hydrogen peroxide (H{sub 2}O{sub 2}) at pH = 5.2. The samples were immersed by 7 days refreshing the solution every day to keep the reactivity of the H{sub 2}O{sub 2}. The surface characteristics that were investigated were: elemental composition by X-ray photoelectron spectroscopy (XPS); topography by atomic force microscopy (AFM) and profilometry; wettability and surface energy by sessile drop contact angle and point of zero charge by titration. Moreover, the variations in the electrochemical response were evaluated by open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) performed before and after the treatment using the Hartman solution as the electrolyte. The XPS results indicated that for both metallic samples, oxidation of the surface was promoted and/or the oxide layer was thicker after the immersion. The roughness and the solid-liquid surface energy were increased; the samples showed a more hydrophilic character after the treatment. However, the surface energy of the solid estimated using the Van Oss–Chaudhury–Good approach showed different trends between the cpTi and the SS surfaces; the polar component decreased for cpTi, while it increased for SS. Finally, the electrochemical results indicated that the corrosion resistance (R{sub cor}) and the pore resistance (R{sub po}) significantly decreased for cpTi, while both resistances were not significantly different for the SS. This is indicative of a higher dissolution of the cpTi compared to SS and the lower R{sub po} means that the species are easily transported through the surface layer, which can be explained in terms of the formation of a porous TiO{sub x} layer, not

  2. SYNCHROTRON RADIATION SOURCES

    Synchrotron radiation is a very bright, broadband, polarized, pulsed source of light extending from the infrared to the x-ray region. It is an extremely important source of Vacuum Ultraviolet radiation. Brightness is defined as flux per unit area per unit solid angle and is normally a more important quantity than flux alone particularly in throughput limited applications which include those in which monochromators are used. It is well known from classical theory of electricity and magnetism that accelerating charges emit electromagnetic radiation. In the case of synchrotron radiation, relativistic electrons are accelerated in a circular orbit and emit electromagnetic radiation in a broad spectral range. The visible portion of this spectrum was first observed on April 24, 1947 at General Electric's Schenectady facility by Floyd Haber, a machinist working with the synchrotron team, although the first theoretical predictions were by Lienard in the latter part of the 1800's. An excellent early history with references was presented by Blewett and a history covering the development of the utilization of synchrotron radiation was presented by Hartman. Synchrotron radiation covers the entire electromagnetic spectrum from the infrared region through the visible, ultraviolet, and into the x-ray region up to energies of many 10's of kilovolts. If the charged particles are of low mass, such as electrons, and if they are traveling relativistically, the emitted radiation is very intense and highly collimated, with opening angles of the order of 1 milliradian. In electron storage rings there are three possible sources of synchrotron radiation; dipole (bending) magnets; wigglers, which act like a sequence of bending magnets with alternating polarities; and undulators, which are also multi-period alternating magnet systems but in which the beam deflections are small resulting in coherent interference of the emitted light.

    The CHARA array is an optical/near infrared interferometer consisting of six 1-meter diameter telescopes the longest baseline of which is 331 meters. With sub-millisecond angular resolution, the CHARA array is able to spatially resolve nearby stellar systems to reveal the detailed structures. To improve the sensitivity and scientific throughput, the CHARA array was funded by NSF-ATI in 2011, and by NSF-MRI in 2015, for an upgrade of adaptive optics (AO) systems to all six telescopes. The initial grant covers Phase I of the adaptive optics system, which includes an on-telescope Wavefront Sensor and non-common-path (NCP) error correction. The WFS use a fairly standard Shack-Hartman design and will initially close the tip tilt servo and log wavefront errors for use in data reduction and calibration. The second grant provides the funding for deformable mirrors for each telescope which will be used closed loop to remove atmospheric aberrations from the beams. There are then over twenty reflections after the WFS at the telescopes that bring the light several hundred meters into the beam combining laboratory. Some of these, including the delay line and beam reducing optics, are powered elements, and some of them, in particular the delay lines and telescope Coude optics, are continually moving. This means that the NCP problems in an interferometer are much greater than those found in more standard telescope systems. A second, slow AO system is required in the laboratory to correct for these NCP errors. We will breifly describe the AO system, and it's current status, as well as discuss the new science enabled by the system with a focus on our YSO program.

One hundred and twenty sisters of breast cancer patients completed questionnaires assessing response efficacy of mammography screenings, physical activity, and fruit and vegetable consumption on decreasing breast cancer risk, breast cancer worry, involvement in their sister’s cancer care, mammography screenings, physical activity, and fruit and vegetable consumption. Results indicate that greater perceived effectiveness for mammograms was associated with a 67% increase in odds of yearly mammograms. Greater involvement in the patient’s care was associated with a 7% decrease in odds of yearly mammograms. Greater perceived effectiveness for physical activity was significantly related to greater physical activity. There was a trend for greater perceived effectiveness for fruits and vegetables to be associated with consuming more fruits and vegetables. Breast cancer worry was not significantly associated with the outcomes. While perceived effectiveness for a specific health behavior in reducing breast cancer risk was consistently related to engaging in that health behavior, women reported significantly lower perceived effectiveness for physical activity and fruits and vegetables than for mammograms. Making women aware of the health benefits of these behaviors may be important in promoting changes.Keywords: breast cancer risk, mammograms, physical activity, diet, perceived effectiveness

  5. Morphological variations caused by fixation techniques may lead to taxonomic confusion in Laeonereis (Polychaeta: Nereididae

    Full Text Available The nereidid polychaete Laeonereis acuta (Treadwell, 1923 is either considered to be a valid species, or a synonym of Laeonereis culveri (Webster, 1879. The species epithet, acuta, refers to the acuminate anterior region of the body followed by a widening that is visible up to the 10th setiger. The relative width of the anterior region of the body, however, has been reported in the taxonomic literature as variable for Laeonereis Hartman, 1945, a genus known from the eastern coast of North America to Patagonia (southern South America. To test whether variations in this character are real, or whether they correspond to an artifact, we analyzed morphological changes associated with different anesthesia and fixation techniques regularly used to prepare specimens of Laeonereis from southern Brazil (formerly reported as L. acuta. Six treatments, including combinations of anesthetics and fixative agents, and a control, were evaluated in groups of 25 adult animals. A simple model II regression analysis on living specimens showed that the growth is approximately isometric. One-way ANOVA was used to compare the treatment effect on the ratio of peristome width: setiger 6 width. This ratio was smaller in non-anesthetized individuals, especially when prepared in formalin and freshwater. When anesthetized with menthol and fixed in formalin with sea water, individuals retained a shape that was closest to their in vivo shape. Consequently, our results suggest that fixation without prior anesthesia is not recommended for morphological and taxonomical studies. Since morphology and morphometrics of the anterior region are consistently influenced by preparation techniques, it is likely that inadequate fixation routines have introduced several errors in the taxonomic and ecological literature of Laeonereis.

    CYP2E1 metabolizes a wide array of small, hydrophobic molecules, resulting in their detoxification or activation into carcinogens through Michaelis-Menten as well as cooperative mechanisms. Nevertheless, the molecular determinants for CYP2E1 specificity and metabolic efficiency toward these compounds are still unknown. Herein, we employed computational docking studies coupled to Molecular Dynamics simulations to provide a critical perspective for understanding a structural basis for cooperativity observed for an array of azoles from our previous binding and catalytic studies (Hartman, JH et al (2014) Biochem Pharmacol 87, 523-33). The resulting 28 CYP2E1 complexes in this study revealed a common passageway for azoles that included a hydrophobic steric barrier causing a pause in movement toward the active site. The entrance to the active site acted like a second sieve to restrict access to the inner chamber. Collectively, these interactions impacted the final orientation of azoles reaching the active site and hence could explain differences in their biochemical properties observed in our previous studies, such as the consequences of methylation at position 5 of the azole ring. The association of a second azole demonstrated significant differences in interactions stabilizing the bound complex than observed for the first binding event. Intermolecular interactions occurred between the two azoles as well as CYP2E1 residue side chains and backbone and involved both hydrophobic contacts and hydrogen bonds. The relative importance of these interactions depended on the structure of the respective azoles indicating the absence of specific defining criteria for binding unlike the well-characterized dominant role of hydrophobicity in active site binding. Consequently, the structure activity relationships described here and elsewhere are necessary to more accurately identify factors impacting the observation and significance of cooperativity in CYP2E1 binding and catalysis

  7. The Economics of Forest Carbon Sequestration: The Challenge for Emissions Offset Trading

    This paper provides an overview of the role that forestry activities can play in mitigating climate change. The price of carbon offset credits is used for incentivizing a reduction in the release of CO2 emissions and an increase in sequestration of atmospheric CO2 through forestry activities. Forestland owners essentially have two options for creating carbon offset credits: (1) avoid or delay harvest of mature timber; or (2) harvest timber and allow natural regeneration or regeneration with `regular' or genetically-enhanced growing stock, storing carbon in post-harvest products, using sawmill and potentially logging residues to generate electricity. In this study, a model representative of the Quesnel Timber Supply Area (TSA) in the BC interior is developed. The objective is to maximize net discounted returns to commercial timber operations (and sale of downstream products) plus the benefits of managing carbon fluxes. The model tracks carbon in living trees, organic matter, and, importantly, post-harvest carbon pools and avoided emissions from substituting wood for non-wood in construction or wood bioenergy for fossil fuels. Model constraints ensure that commercial forest management is sustainable, while carbon prices incentivize sequestration to ensure efficient mitigation of climate change. The results are confirmed more generally by comparing the carbon fluxes derived from the integrated forest management model with those from a Faustmann-Hartman rotation age model that explicitly includes benefits of storing carbon. One other question is addressed: If carbon offsets are created when wood biomass substitutes for fossil fuels in power generation, can one count the saved emissions from steel/cement production when wood substitutes for non-wood materials in construction?

    In the present study, entropy generation due to mixed convection in a partially heated square double lid driven cavity filled with Al2O3 -water nanofluid under the influence of inclined magnetic field is numerically investigated. At the lower wall of the cavity two heat sources are fixed, with the condition that the remaining part of the bottom wall is kept insulated. Top wall and vertically moving walls are maintained at constant cold temperature. Buoyant force is responsible for the flow along with the two moving vertical walls. Governing equations are discretized in space using LBB-stable finite element pair Q2 / P1disc which lead to 3rd and 2nd order accuracy in the L2-norm for the velocity/temperature and pressure, respectively and the fully implicit Crank-Nicolson scheme of 2nd order accuracy is utilized for the temporal discretization. The discretized systems of nonlinear equations are treated by using the Newton method and the associated linear subproblems are solved by means of Guassian elimination method. Numerical results are presented and analyzed by means of streamlines, isotherms, tables and some useful plots. Impacts of emerging parameters on the flow, in specific ranges such as Reynolds number (1 ≤ Re ≤ 100) , Richardson number (1 ≤ Ri ≤ 50) , Hartman number (0 ≤ Ha ≤ 100) , solid volume fraction (0 ≤ ϕ ≤ 0.2) as well as the angles of inclined magnetic field (0 ° ≤ γ ≤ 90 °) are investigated and the findings are exactly of the same order as that of the previously performed analysis. Calculation of average Nusselt number, entropy generation due to heat transfer, fluid friction and magnetic field, total entropy generation, Bejan number and kinetic energy are the main focus of our study.

  9. Timing of the deposition of uppermost Cretaceous and Paleocene coal-bearing deposits in the Greater Glendive area, Montana and North Dakota

    1996-02-01

    With the aid of a grant from the National Geographic Society, a cooperative agreement with the State University of New York at Stony Brook, and contract with the U.S. Department of Energy, Late Cretaceous and Paleocene geologic and paleontologic field studies were undertaken in Makoshika, State Park and vicinity, Dawson County, Montana. This region was chosen as a study area because of its potential for yielding new fossil localities and extensive exposures both above and below the K/T boundary, as suggested by previous research by David W. Krause and Joseph H. Hartman. Related field studies were also undertaken in areas adjacent to the Cedar Creek Anticline in North Dakota. This work was part of ongoing research to document change in the composition of mammalian and molluscan faunas during the Late Cretaceous and Paleocene and to relate observed patterns to floral and invertebrate changes in composition. This study focuses on the record of mammals and mollusks in the Makoshika stratigraphic section and places old and new observations into a paleomagnetic and palynomorph framework. Of particular interest is the appearance and diversification of archaic ungulate mammals. Simultaneous dinosaur extinction with ungulate radiation has been invoked in gradual, as opposed to catastrophic, models of faunal change at the K/T boundary. However, supposed Cretaceous localities bearing archaic ungulates and other mammals of {open_quotes}Paleocene aspect{close_quotes} may be the product of faunal reworking. Elsewhere in the Williston Basin (e.g., Garfield and McCone Counties, Montana), the molluscan record of uppermost Cretaceous and Paleocene strata indicates the extinction of all of the highly sculptured unionid bivalves just prior to the onset of coal swamps and subsequent coal formation.

  10. Chirality Switching by Martensitic Transformation in Protein Cylindrical Crystals: Application to Bacterial Flagella

    Science.gov (United States)

    Komai, Ricardo Kiyohiro

    Martensitic transformations provide unique engineering properties that, when designed properly, become important parts of new technology. Martensitic transformations have been studied for many years in traditional alloys (iron, steel, titanium, etc.), however there is still much to be learned in regards to these transformations in biological materials. Olson and Hartman showed in 1982 that these transformations are also observed in bacterial flagella and T4 bacteriophage viral sheaths, allowing for propulsion of bacteria in a fluid environment and, for the virus, is responsible for the infection mechanism. This work demonstrates, using the bacterial flagella as an example, that these transformations can be modelled using thermodynamic methods that are also used to model the transformations in alloys. This thesis work attempts to explain the transformations that occur in bacterial flagella, which are capable of small strain, highly reversible martensitic transformations. The first stress/temperature phase diagrams of these flagella were created by adding the mechanical energy of the transformation of the flagella to limited chemical thermodynamics information of the transformation. Mechanical energy is critical to the transformation process because the bacterial body applies a torque to the radius of the flagella. Finally, work has begun and will be completed in regards to understanding the kinetics of the transformation of the flagella. The motion of the transformation interface can be predicted by using a Landau-Ginzburg model. The crystallography of the transformation in bacterial flagella is also being computed to determine the invariant lines of transformation that occur within this cylindrical crystal. This work has shown that it is possible to treat proteins in a similar manner that alloys are treated when using thermodynamic modelling. Much can be learned from translating what is known regarding phase transformations in hard material systems to soft, organic

    Since the introduction of the pyramid wavefront sensor [P-WFS] concept (Ragazzoni), numerous investigations have clearly shown its ability to achieve better performance (sensitivity, dynamic range) than the standard Shack-Hartman [SH-WFS]. It has recently been successfully implemented on LBT and has already been provided very interesting results (Esposito et al). Then, most of the future adaptive optics [AO] systems, mainly for ELT instrumentation, will probably integrate one or several pyramidal sensors. However, the pyramid behavior still needs to be extensively studied in order to ensure its optimization in real conditions of operation. So, the coupling in an AO loop and the control of this type of sensor is fundamental for an efficient implementation in the future AO systems. At LAM, we recently carried out in labs demonstration of an extremely performant pyramid sensor (up to 60x60), using particularly an OCAM2 detector (1.5 kHz, RON close to zero). Both modulated and fixed configurations are investigated and compared with numerical models. The P-WFS is being coupled with a dedicated RTC and a 12×12 DM to achieve a first AO closed loop operation. For modulation, a fine control is needed: a specific electronic module, interfaced with the RTC, is being developed to drive the TT mirror (OCAM2 triggering). Then, various TT mirrors are under test to determine a suitable one. After tests of the pyramid specificities (optimiziation, calibration and operation procedures), the P-WFS will be tested on-sky and compared with an already existing SH-WFS (using the same OCAM²) on the ONERA bench.

  12. Hearing and sports: a bidirectional interaction. [Audición y Control motor: Una relación recíproca].

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Introduction Motor control is crucially dependent on many sensory inputs that involve classically the proprioreceptors located in the tendons, joints and the muscle itself as well as inputs from the vestibular organ and eyes (Fitzpatrick and McCloskey, 1994. However, additional sensory input from the auditory system is often necessary to perform the sport-associated complex motor-tasks. This holds not only for team sports that requires continuous communication with the other players but also for others such as figure skating or gymnastics where the movements of the body need to be coordinated with music. In addition, hearing is also important for avoiding accidents e.g. during skiing to recognize other people on the same track. Conversely, specific sports wear used in these sports may negatively influence hearing as it was shown for ski helmets that reduce perception of safety-relevant frequencies (Ruedl, Kopp, Burtscher, Zorowka, Weichbold, Stephan, Koci and Seebacher, 2014; Tudor, Ruzic, Bencic, Sestan and Bonifacic, 2010. Moreover, the reaction time and force generated during voluntary contractions could be influenced by sound. For instance, runners closer to the starter's pistol at Olympic Games react sooner than runners farther away (Brown, Kenwell, Maraj and Collins, 2008. Finally, hearing could even influence the overall physical fitness as it might be reduced in deaf children (Hartman, Visscher and Houwen, 2007 although other studies could not confirm (Wierzbicka-Damska, Samolyk, Jethon, Wiercinska and Murawska-Cialowicz, 2005. In the elderly, sensory deficits such as poor vision and hearing may increase the risk of mobility decline (Viljanen, Kaprio, Pyykko, Sorri, Koskenvuo and Rantanen, 2009a; Viljanen, Kaprio, Pyykko, Sorri, Pajala, Kauppinen, Koskenvuo and Rantanen, 2009b.

    Hydrogen adsorption in porous, high surface area, and stable metal organic frameworks (MOF's) appears a novel route towards hydrogen storage materials [N.L. Rosi, J. Eckert, M. Eddaoudi, D.T. Vodak, J. Kim, M. O'Keeffe, O.M. Yaghi, Science 300 (2003) 1127; J.L.C. Rowsell, A.R. Millward, K. Sung Park, O.M. Yaghi, J. Am. Chem. Soc. 126 (2004) 5666; G. Ferey, M. Latroche, C. Serre, F. Millange, T. Loiseau, A. Percheron-Guegan, Chem. Commun. (2003) 2976; T. Loiseau, C. Serre, C. Huguenard, G. Fink, F. Taulelle, M. Henry, T. Bataille, G. Férey, Chem. Eur. J. 10 (2004) 1373]. A prerequisite for such materials is sufficient adsorption interaction strength for hydrogen adsorbed on the adsorption sites of the material because this facilitates successful operation under moderate temperature and pressure conditions. Here we report detailed information on the geometry of the hydrogen adsorption sites, based on the analysis of inelastic neutron spectroscopy (INS). The adsorption energies for the metal organic framework MOF5 equal about 800 K for part of the different sites, which is significantly higher than for nanoporous carbon materials (˜550 K) [H.G. Schimmel, G.J. Kearley, M.G. Nijkamp, C.T. Visser, K.P. de Jong, F.M. Mulder, Chem. Eur. J. 9 (2003) 4764], and is in agreement with what is found in first principles calculations [T. Sagara, J. Klassen, E. Ganz, J. Chem. Phys. 121 (2004) 12543; F.M. Mulder, T.J. Dingemans, M. Wagemaker, G.J. Kearley, Chem. Phys. 317 (2005) 113]. Assignments of the INS spectra is realized using comparison with independently published model calculations [F.M. Mulder, T.J. Dingemans, M. Wagemaker, G.J. Kearley, Chem.

    Fournier gangrene is a very rare and a rapidly progressing, polymicrobial necrotizing faciitis or myonecrosis of the perineal, perianal and genital regions, with a high mortality rate. Infection is associated with superficial traum, urological and colorectal diseases and operations. The most commonly found bacteria are Escherichia coli followed by Bacteroides and streptococcal species. Diabetes mellitus, alcoholism, and immunosuppression are perpetuating co-factors. Fournier's gangrene complicating inflammatory bowel disease has been reported in three patients so far, two with Crohn's disease. A 78-year-old man diagnosed with ulcerative pancolitis was referred for fever, and painful perianal and scrotal swelling after perianal surgery for a horseshoe-type perianal abscess. Since bowel disease diagnosis, patient was on mesalazine and achieved long-term remission. Perianal abscess occurred suddenly one week before perianal surgery without any evidence of pre-existing fistula or other abnormalities. Physical examination showed extensive edema and crepitus of perineum and genitalia and patient had symptoms of significant toxicity. The diagnosis of Fournier's gangrene was made and patient underwent emergency surgery with extensive surgical debridement of the scrotal and perianal area and Hartman procedure with a diverting colostomy. In addition, patient started on therapy with mesalazine 3gr, methylprednisolone 16 mg, parenteral nutrition and broad spectrum of antibiotics. Two days after the first operation the patient needed a second operation for perianal debridement. On the fourth day, blood cultures showed E. coli. Patient had an uneventful recovery and was discharged after 34 days of hospitalization. On follow up, disease review is scheduled and colostomy closure is planned.

    Full Text Available The research on aluminium content was conducted in water and on aquatic flora of Polish lakes in the central part of the coast. The study included the lakes Sarbsko, Choczewskie, Bia.e, K.odno, D.brze and Salino investigated in the summer of 2013. The examined lakes belong mainly to the direct basin of the Baltic Sea. Samples of aquatic plants and lake waters were collected. In the water samples pH and electrolytic conductivity were measured. The aluminium content was determined both in water and aquatic plants. Submerged hydromacrophyte studies included Myriophyllum alterniflorum L., Potamogeton perfoliatus L. and Ceratophyllum demersum L. Emergent hydromacrophyte studies included Phragmites australis (Cav. Trin. ex Steud., Juncus bulbosus L., Iris pseudacorus L., Eleocharis palustris (L. Roem. % Schult., Phalaris arundinacea L., Carex riparia Curt., Mentha aquatic L., Stratiotes aloides L., Alisma plantago-aquatica L., Glyceria maxima (Hartman Holmb., Sagittaria sagittifolia L., Scirpus lacustris L. and Typha angustifolia L. The purpose of this investigation was the determination of the aluminium content in submerged and emergent hydromacrophytes and also the definition of their bioaccumulative abilities. The average concentration of aluminium in water was 2.68 fęg Al dm.3. The average content of aluminium in plants was 2.8015 mg Al kg.1. The bioaccumulation factor ranged from BCF=19.74 to BCF=16619. On the basis of the analysis of the aluminium content in water and aquatic plants results show that both water and plants were characterized by a moderate level of aluminium. The recorded concentrations indicate a mid-range value and are much lower than those which are quoted for a variety of surface waters in various parts of the world.

    The family Nereididae includes more than 500 polychaete species described worldwide, and includes species common in many benthic environments, but some other species may tolerate freshwater or can even thrive in humid substrates in tropical forests. In estuarine environments, nereidid polychaetes can be abundant and relevant as a food source for resident or migratory birds. Laeonereis culveri (Webster, 1879) is a common estuarine species found in tropical and subtropical Atlantic American shores and was described from New Jersey; its median and posterior parapodia have upper notopodial ligules usually longer than the lower ones, and the latter are parallel to the notaciculae throughout the body. L. culveri distribution is from Connecticut to central Argentina; however, this wide distribution might be due to the inclusion of several other species as junior synonyms, despite that some morphological differences were found between them. One of such species is L. nota (Treadwell, 1941), that was described from Texas; its parapodia have notopodial ligules of about the same size, and the lower ones are oblique to the notaciculae. In order to clarify the differences between these two species, and to define which inhabits the Northwestern Caribbean region, topotype materials from these two species and specimens from Chetumal Bay were collected, and their morphological features were compared. Our results indicated that L. culveri and L. nota are different species and that the latter is found in Chetumal Bay. On the basis of mature specimens, L. culveri is hereby restricted to the Northern Gulf of Mexico and Northwestern Atlantic Ocean, and L. nota are reinstated and its distribution extends from Texas, in the Gulf of Mexico to Chetumal Bay, in the Northwestern Caribbean Sea. A key to identify all species in Laeonereis Hartman (1945) is also included.
