    Three figures of merit are proposed as quality measures for surface plasmon waveguides. They are defined as benefit-to-cost ratios where the benefit is confinement and the cost is attenuation. Three different ways of measuring confinement are considered, leading to three figures of merit. One of the figures of merit is connected to the quality factor. The figures of merit were then used to assess and compare the wavelength response of hree popular 1-D surface plasmon waveguides: the single metal-dielectric interface, the metal slab bounded by dielectric and the dielectric slab bounded by metal. Closed form expressions are given for the figures of merit of the single metal-dielectric interface.

    A new facility at the Goddard Space Flight Center is designed to measure with unusual accuracy the surface figure of mirrors at cryogenic temperatures down to 12 K. The facility is currently configured for spherical mirrors with a radius of curvature (ROC) of 600 mm, and apertures of about 150 mm or less. The goals of the current experiment were to 1) Obtain the best possible estimate of test mirror surface figure, S(x,y) at 87 K and 20 K; 2) Obtain the best estimate of the cryo-change, Delta (x,y): the change in surface figure between room temperature and the two cryo-temperatures; and 3) Determine the uncertainty of these measurements, using the definitions and guidelines of the ISO Guide to the Expression of Uncertainty in Measurement. A silicon mirror was tested, and the cry-change from room temperature to 20K was found to be 3.7 nm rms, with a standard uncertainty of 0.23 nm in the rms statistic. Both the cryo-change figure and the uncertainty are among the lowest such figures yet published. This report describes the facilities, experimental methods, and uncertainty analysis of the measurements.

  6. Influence of material removal programming on ion beam figuring of high-precision optical surfaces

    Ion beam figuring (IBF) provides a nanometer/subnanometer precision fabrication technology for optical components, where the surface materials on highlands are gradually removed by the physical sputtering effect. In this deterministic method, the figuring process is usually divided into several iterations and the sum of the removed material in each iteration is expected to approach the ideally removed material as nearly as possible. However, we find that the material removal programming in each iteration would influence the surface error convergence of the figuring process. The influence of material removal programming on the surface error evolution is investigated through the comparative study of the contour removal method (CRM) and the geometric proportion removal method (PRM). The research results indicate that the PRM can maintenance the smoothness of the surface topography during the whole figuring process, which would benefit the stable operation of the machine tool and avoid the production of mid-to-high spatial frequency surface errors. Additionally, the CRM only has the corrective effect on the area above the contour line in each iteration, which would result in the nonuniform convergence of the surface errors in various areas. All these advantages distinguish PRM as an appropriate material removal method for ultraprecision optical surfaces.

  7. Material removal and surface figure during pad polishing of fused silica

    2009-05-04

    The material removal and surface figure after ceria pad polishing of fused silica glass have been measured and analyzed as a function of kinematics, loading conditions, and polishing time. Also, the friction at the workpiece/lap interface, the slope of the workpiece relative to the lap plane, and lap viscoelastic properties have been measured and correlated to material removal. The results show that the relative velocity between the workpiece & lap (determined by the kinematics) and the pressure distribution determine the spatial and temporal material removal and hence the final surface figure of the workpiece. In the case where the applied loading and relative velocity distribution over the workpiece are spatially uniform, a significant non-uniform spatial material removal from the workpiece surface is observed. This is due to a non-uniform pressure distribution resulting from: (1) a moment caused by a pivot point and interface friction forces; (2) viscoelastic relaxation of the polyurethane lap; and (3) a physical workpiece/lap interface mismatch. Both the kinematics and these contributions to the pressure distribution are quantitatively described, and then combined to form a spatial and temporal Preston model & code for material removal (called Surface Figure or SurF{copyright}). The surface figure simulations are consistent with the experiment for a wide variety of polishing conditions. This study is an important step towards deterministic full-aperture polishing, which would allow optical glass fabrication to be performed in a more repeatable, less iterative, and hence more economical manner.

    Nepenthes pitcher inspired slippery lubricant-infused porous surfaces greatly impact the understanding of liquid-repellent surfaces construction and have attracted extensive attention in recent years due to their potential applications in self-cleaning, anti-fouling, anti-icing, etc. In this work, we have successfully fabricated transparent slippery lubricant-infused surfaces based on breath figure patterns (BFPs). Large-area BFPs with interconnected pores were initially formed on the glass substrate and then a suitable lubricant was added onto the surfaces. The interconnected pores in BFPs were able to hold the lubricant liquid in place and form a stable liquid/solid composite surface capable of repelling a variety of liquids. The liquid-repellent surfaces show extremely low critical sliding angles for various liquids, thus providing the surfaces with efficient self-cleaning property. It was also found that the liquid droplets' sliding behaviors on the surfaces were significantly influenced by the tilting angle of the substrate, liquid volume, liquid chemical properties, and pore sizes of the surfaces.

  10. X-ray Multilayers and Thin-Shell Substrate Surface-Figure Correction

    Science.gov (United States)

    Windt, David

    We propose a comprehensive experimental research program whose two main goals are (a) to improve the performance of hard X-ray multilayer coatings and (b) to develop a high-throughput method to correct mid-frequency surface errors in thin-shell mirror substrates. Achieving these goals will enable the cost-effective construction of light- weight, highly-nested X-ray telescopes having greater observational sensitivity, wider energy coverage, and higher angular resolution than can be achieved at present. The realization of this technology will thus benefit the development of a variety of Explorer- class NASA X-ray astronomy missions now being formulated for both the soft and hard X-ray bands, and will enable the construction of future facility-class X-ray missions that will require both high sensitivity and high resolution. Building on the success of our previous APRA-funded research, we plan to investigate new thin-film growth techniques, new materials, and new aperiodic coating designs in order to develop new hard X-ray multilayers that have higher X-ray reflectance, wider energy response, lower film stress, and good stability, and that can be produced more quickly, at reduced cost. Additionally, we propose to build upon our extensive experience in sub-nm film-thickness control using velocity modulation and masked deposition techniques, and in the recent development of low-roughness, low-stress films grown by reactive sputtering, in order to develop new methods for correcting mid-frequency surface errors in thin-shell mirror substrates using both differential deposition and ion-beam figuring, either alone or in combination. These two surface-correction techniques already being used for sub-nm figuring of precision optics in a variety of disciplines, including diffraction-limited EUV lithography and synchrotron applications requiring sub-micron focusing are ideally suited for controlling mm-scale surface errors in the thin-shell substrates used for astronomical X

    1987-01-01

    At present, grazing incidence mirrors are used almost exclusively as the first optical element in VUV and soft x-ray synchrotron radiation beamlines. The performance of these mirrors is determined by thermal and mechanical stress-induced figure errors as well as by figure errors remaining from the grinding and polishing process. With the advent of VUV and soft x-ray undulators and wigglers has come a new set of thermal stress problems related to both the magnitude and the spatial distribution of power from these devices. In many cases the power load on the entrance slits and gratings in these beamlines is no longer negligible. The dependence of thermally-induced front-end mirror figure errors on various storage ring and insertion device parameters (especially those at the National Synchrotron Light Source) and the effects of these figure errors on two classes of soft x-ray beamlines are presented.

    Differential deposition corrects the low- and mid- spatial-frequency deviations in the axial figure of Wolter-type grazing incidence X-ray optics. Figure deviations is one of the major contributors to the achievable angular resolution. Minimizing figure errors can significantly improve the imaging quality of X-ray optics. Material of varying thickness is selectively deposited, using DC magnetron sputtering, along the length of optic to minimize figure deviations. Custom vacuum chambers are built that can incorporate full-shell and segmented Xray optics. Metrology data of preliminary corrections on a single meridian of full-shell x-ray optics show an improvement of mid-spatial frequencies from 6.7 to 1.8 arc secs HPD. Efforts are in progress to correct a full-shell and segmented optics and to verify angular-resolution improvement with X-ray testing.

    Consensual stereotypes of some groups are relatively accurate, whereas others are not. Previous work suggesting that national character stereotypes are inaccurate has been criticized on several grounds. In this article we (a) provide arguments for the validity of assessed national mean trait levels as criteria for evaluating stereotype accuracy; and (b) report new data on national character in 26 cultures from descriptions (N=3,323) of the typical male or female adolescent, adult, or old person in each. The average ratings were internally consistent and converged with independent stereotypes of the typical culture member, but were weakly related to objective assessments of personality. We argue that this conclusion is consistent with the broader literature on the inaccuracy of national character stereotypes. PMID:24187394

  14. La petite fille de la surface comme figure de la dissolution du soi

    2015-12-01

    Full Text Available This article follows the traces of the jeune fille that can be found throughout Deleuze’s Logic of Sense, so as to pave the way for further reflection on possible links between feminism(s and Deleuzian thought. By analysing the key concepts of Logic of Sense, it is shown that Deleuze conceptualizes the jeune fille as the figure of the dissolution of the self, carried out through a close reading of Leibniz, Nietzsche and psychoanalysis. The jeune fille/the feminine is accordingly construed as an aleatory point at the intersection of possible world(s. This in turn resonates with Luce Irigaray’s project with respect to sexual difference, in which she calls upon feminists to create conceptions of the feminine as pure difference, not captured by the name of the Father or the patriarchal symbolic system.

    Brookhaven National Laboratory is the site of the National Synchrotron Light Source (NSLS); an electron synchrotron which is an intense source of hard and soft x-rays. Since there are no effective refracting elements for x rays, this radiation must be manipulated and focused by mirrors configured to give high reflectivity. This paper describes methods of predicting the degradation of the performance of a simple imaging system in terms of the statistics of the shape errors of the focusing element, and conversely, of specifying those statistics in terms of requirements on image quality. Results are illustrated for a normal-incidence x-ray mirrors having figure errors plus conventional and/or fractal finish errors

    The structure, dynamical equilibrium, and evolution of Saturn's moon Iapetus are studied. It has been shown that, in the current epoch, the oblateness of the satellite ɛ2 ≈ 0.046 does not correspond to its angular velocity of rotation, which causes the secular spherization behavior of the ice shell of Iapetus. To study this evolution, we apply a spheroidal model, containing a rock core and an ice shell with an external surface ɛ2, to Iapetus. The model is based on the equilibrium finite-difference equation of the Clairaut theory, while the model parameters are taken from observations. The mean radius of the rock core and the oblateness of its level surface, ɛ1 ≈ 0.028, were determined. It was found that Iapetus is covered with a thick ice shell, which is 56.6% of the mean radius of the figure. We analyze a role of the core in the evolution of the shape of a gravitating figure. It was determined that the rock core plays a key part in the settling of the ice masses of the equatorial bulge, which finally results in the formation of a large circular equatorial ridge on the surface of the satellite. From the known mean altitude of this ice ridge, it was found that, in the epoch of its formation, the rotation period of Iapetus was 166 times shorter than that at present, as little as T ≈ 11h27m. This is consistent with the fact that a driving force of the evolution of the satellite in our model was its substantial despinning. The model also predicts that the ice ridge should be formed more intensively in the leading (dark and, consequently, warmer) hemisphere of the satellite, where the ice is softer. This inference agrees with the observations: in the leading hemisphere of Iapetus, the ridge is actually high and continuous everywhere, while it degenerates into individual ice peaks in the opposite colder hemisphere.

    Sanabria, Orlando

    Guided by organizational theory, this phenomenological study explored the factors affecting forecast preparation and inaccuracies during the construction of fossil fuel-fired power plants in the United States. Forecast inaccuracies can create financial stress and uncertain profits during the project construction phase. A combination of purposeful and snowball sampling supported the selection of participants. Twenty project managers with over 15 years of experience in power generation and project experience across the United States were interviewed within a 2-month period. From the inductive codification and descriptive analysis, 5 themes emerged: (a) project monitoring, (b) cost control, (c) management review frequency, (d) factors to achieve a precise forecast, and (e) factors causing forecast inaccuracies. The findings of the study showed the factors necessary to achieve a precise forecast includes a detailed project schedule, accurate labor cost estimates, monthly project reviews and risk assessment, and proper utilization of accounting systems to monitor costs. The primary factors reported as causing forecast inaccuracies were cost overruns by subcontractors, scope gaps, labor cost and availability of labor, and equipment and material cost. Results of this study could improve planning accuracy and the effective use of resources during construction of power plants. The study results could contribute to social change by providing a framework to project managers to lessen forecast inaccuracies, and promote construction of power plants that will generate employment opportunities and economic development.

  7. Optimization of Gas Composition Used in Plasma Chemical Vaporization Machining for Figuring of Reaction-Sintered Silicon Carbide with Low Surface Roughness.

    2018-02-05

    In recent years, reaction-sintered silicon carbide (RS-SiC) has been of interest in many engineering fields because of its excellent properties, such as its light weight, high rigidity, high heat conductance and low coefficient of thermal expansion. However, RS-SiC is difficult to machine owing to its high hardness and chemical inertness and because it contains multiple components. To overcome the problem of the poor machinability of RS-SiC in conventional machining, the application of atmospheric-pressure plasma chemical vaporization machining (AP-PCVM) to RS-SiC was proposed. As a highly efficient and damage-free figuring technique, AP-PCVM has been widely applied for the figuring of single-component materials, such as Si, SiC, quartz crystal wafers, and so forth. However, it has not been applied to RS-SiC since it is composed of multiple components. In this study, we investigated the AP-PCVM etching characteristics for RS-SiC by optimizing the gas composition. It was found that the different etching rates of the different components led to a large surface roughness. A smooth surface was obtained by applying the optimum gas composition, for which the etching rate of the Si component was equal to that of the SiC component.

    Public perceptions of climate change and meta-perceptions of the public and climate scientist's perceptions of climate change were assessed to benchmark the National Network for Climate Change Interpretation's impacts. Meta-perceptions are important to examine because they can have implications for willingness to take action to address climate change. For instance, recent research suggests a tendency to misperceive that there is disagreement among climate scientists is predictive of lack of support for climate change policies. Underestimating public concern about climate change could also be problematic: it could lead individuals to withdraw from personal efforts to reduce impact and engage others in discussions about climate change. Presented results will demonstrate that respondents in a national survey underestimated the percent of the public who were very concerned, concerned or cautious about climate change and overestimated the extent others were disengaged, doubted, or non-believers. They underestimated the percent of the public who likely believed that humans caused climate change and overestimate the percent that believed climate change was not happening nor human induced. Finally, they underestimated the percent of the public that believed climate change threatened ocean health. The results also explore sources of misperceptions. First, correlates with TV viewing habits suggest that inaccuracy is a result of too little attention to network news, with one exception: Greater attention to FOX among doubters reduced accuracy. Second, adding to other evidence that basic cognitive heuristics (such as availability heuristic) influence perceptions of climate change, we show that that false consensus effects account for meta-perceptions of the public and climate scientists beliefs. The false consensus effect, in combination with underestimating concern among the public, results in those most concerned about climate change and those who believe it to be human

    Breath figures (BFs) are a kind of water droplet arrays that can be formed by condensing aqueous vapor onto a cold surface, such as dewy phenomenon on a spider web. This study developed a BF-inspired approach for direct introduction of desired materials onto the textile surfaces with three-dimensionally conformal porous microstructures by the evaporation of solution-coated fabric under high humidity environment, which brings a brand-new kind of modified textiles, three-dimensionally conformal porous microstructured fabrics (CPMFs). Such kind of CPMFs can possess customized multifunctional properties of introduced materials, and meanwhile maintain the inherent properties and unique texture features of fabrics. This nature-inspired BF approach is robust and versatile for customized preparation of CPMFs based on different fabrics with different common polymers. Moreover, it is also feasible for one-step functionalization of CPMFs by the incorporation of nanoparticles (such as titanium dioxide nanoparticles, TiO 2 NPs) into the porous microstructures during the BF process. Comparing to the sample modified without porous microstructures, the resultant TiO 2 NPs-incorporated CPMFs show an obviously enhanced performance on photocatalytic degradation of pollutants under the same ultraviolet irradiation conditions.

  19. Optimal Ordering Policy of a Risk-Averse Retailer Subject to Inventory Inaccuracy

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Inventory inaccuracy refers to the discrepancy between the actual inventory and the recorded inventory information. Inventory inaccuracy is prevalent in retail stores. It may result in a higher inventory level or poor customer service. Earlier studies of inventory inaccuracy have traditionally assumed risk-neutral retailers whose objective is to maximize expected profits. We investigate a risk-averse retailer within a newsvendor framework. The risk aversion attitude is measured by conditional-value-at-risk (CVaR. We consider inventory inaccuracy stemming both from permanent shrinkage and temporary shrinkage. Two scenarios of reducing inventory shrinkage are presented. In the first scenario, the retailer conducts physical inventory audits to identify the discrepancy. In the second scenario, the retailer deploys an automatic tracking technology, radiofrequency identification (RFID, to reduce inventory shrinkage. With the CVaR criterion, we propose optimal policies for the two scenarios. We show monotonicity between the retailer’s ordering policy and his risk aversion degree. A numerical analysis provides managerial insights for risk-averse retailers considering investing in RFID technology.

    The objective of this work, is that starting from a data file coming from a spectra that has been softened, and of the one that have been generated its coordinates to project it in stereographic form, to create the corresponding polar figure making use of the Cyber computer of the ININ by means of the GRAPHOS package. This work only requires a Beta, Fi and Intensity (I) enter data file. It starts of the existence of a softened spectra of which have been generated already with these data, making use of some language that in this case was FORTRAN for the Cyber computer, a program is generated supported in the Graphos package that allows starting of a reading of the Beta, Fi, I file, to generate the points in a stereographic projection and that it culminates with the graph of the corresponding polar figure. The program will request the pertinent information that is wanted to capture in the polar figure just as: date, name of the enter file, indexes of the polar figure, number of levels, radio of the stereographic projection (cms.), crystalline system to which belongs the sample, name the neuter graph file by create and to add the own general data.

    Mosetti, Renzo A.

    2017-05-01

    In this paper the conceptual framework for the regulation of rising global temperature is posed in terms of control systems theory. It is shown here that, for an optimal regulation of greenhouse gas emissions, a closed-loop feedback control system based on climate models is necessary. Furthermore, the concept of the Internal Model Principle (IMP) is crucial in attaining the proposed limits of the temperature increase. This is due to the presence of inaccuracies in the existing climate models, and to a lack of knowledge.

    Neste Corporation's net sales during 1991 totalled USD 12.6 billion, an increase of 11 % over the figure for 1990. The largest growth in net sales took place in Neste Oil's trading activities and sales of in-house-produced crude oil. In the chemicals sector. particular growth was recorded in resins production. Gas, Shipping and Exploration and Production performed slightly better than during 1990. Oil's performance remained satisfactory. The performance of Chemicals, however, fell back considerably, primarily, as a result of the worldwide drop in prices in the petrochemicals and plastics industries. As a result, the Corporation's overall result was substantially below the good level recorded in 1990. The Corporation's operating margin totalled USD 650 million

    Several spatial measures of community food access identifying so called "food deserts" have been developed based on geospatial information and commercially-available, secondary data listings of food retail outlets. It is not known how data inaccuracies influence the designation of Census tracts as areas of low access. This study replicated the U.S. Department of Agriculture Economic Research Service (USDA ERS) food desert measure and the Centers for Disease Control and Prevention (CDC) non-healthier food retail tract measure in two secondary data sources (InfoUSA and Dun & Bradstreet) and reference data from an eight-county field census covering169 Census tracts in South Carolina. For the USDA ERS food deserts measure accuracy statistics for secondary data sources were 94% concordance, 50-65% sensitivity, and 60-64% positive predictive value (PPV). Based on the CDC non-healthier food retail tracts both secondary data demonstrated 88-91% concordance, 80-86% sensitivity and 78-82% PPV. While inaccuracies in secondary data sources used to identify low food access areas may be acceptable for large-scale surveillance, verification with field work is advisable for local community efforts aimed at identifying and improving food access.

Javanese kiai mainly believe that a pesantren is a small palace where he becomes the ultimate source of power and authority. Even though he lives in a rural village, he becomes a member of elite group in social, politic and economic sides in the society. Kiai who leads big pesantren has successfully enlarged their power in term of nation so kiai could be accepted in national elite. The position of kiai is higher among all pesantren elements. The degree as an Islamic scholar is exactly a sacred degree in pesantren culture and tradition. Without his figure, it is impossible for a pesantren to develop and survive. Kiai holds an ultimate position on educate the behavior and morality of the santri (students to be qualified and compatible Muslims generation. Kiai is not only a leader but he is also the man behind the leadership itself in supporting the progress of Islamic education institution for Muslims generations.

    Great improvement has been made in the past several years in the quality of optical components used in synchrotron radiation (SR) beamlines. Most of this progress has been the result of vastly improved metrology techniques and instrumentation permitting rapid and accurate measurement of the surface finish and figure on grazing incidence optics. A significant theoretical effort has linked the actual performance of components used as x-ray wavelengths to their topological properties as measured by surface profiling instruments. Next-generation advanced light sources will require optical components and systems to have sub-arc second surface figure tolerances. This paper will explore the consequences of these requirements in terms of manufacturing tolerances to see if the present manufacturing state-of-the-art is capable of producing the required surfaces. 15 refs., 14 figs., 2 tabs

    2017-11-10

    The edge effect is regarded as one of the most difficult technical issues for fabricating large primary mirrors, as it can greatly reduce the key performance of the optical system. Ion beam figuring (IBF) has the advantage of no edge effect, so we can use it to remove high points on the edge and improve surface accuracy. The edge local correction method (ELCM) of IBF processes only the surface edge zone, and is very different from the current full caliber figuring method (FCFM). Therefore, it is necessary to study the ELCM of IBF. In this paper, the key factors of ELCM are analyzed, such as dwell time algorithm, edge data extension methods, and the outward dimension of the starting figuring point. At the same time, the distinctions between ELCM and FCFM are compared. Finally, a 142 mm diameter fused silica mirror is fabricated to verify the validity of the theoretical of ELCM. The experimental results indicate that the figuring precision and efficiency can be obviously improved by ELCM.

    The authors examined problem behaviors in preschool children as a function of perceived competence. Prior research has demonstrated a link between inaccuracy of self-perceptions and teacher-reported externalizing behaviors in preschool aged boys. This study extended past research by adding data collected from observed behaviors in a laboratory setting, as well as parent reports of internalizing and externalizing behaviors. Five-year-old children completed the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PSPCSA) in the lab, participated in a 10-min puzzle interaction task with their cotwin and mother, and completed a short task assessing cognitive abilities. Children were grouped into 3 self-esteem categories (unrealistically low, realistic, and unrealistically high) based on comparisons of self-reported (PSPCSA) versus actual competencies for maternal acceptance, peer acceptance, and cognitive competence. Results showed that children who overreported their maternal acceptance and peer acceptance had significantly more parent-reported externalizing problems as well as internalizing problems. There were no significant differences in accuracy for cognitive competence. The findings from this study underscore the negative impact of unrealistically high self-appraisal on problem behaviors in young children.

    Full Text Available Abstract. The subject of this article is the assessment of measurement uncertainty with the kinematic telescopic bar QC20-W in the accuracy test of MOTOMAN HP20 industrial robot. The measurements were performed to determine the statistical uncertainty of error measurement using the system applied. Analysed in tests was the robot’s ability to recreate a circular outline through standard, complex and extended measurement of uncertainty measurement. The obtained results were served to perform rapid evaluation of robot inaccuracy. These uncertainties were based on the information included in the device calibration certificate (estimated with method B but also on the basis of measurements and statistical data (estimated with method A. These components of the uncertainty budget take relatively small values (uc=0.818÷4.130; U=1.636÷8.260 for k=2, which proves that a properly selected method was applied to the research task. The method of research and calculation precisely identified key uncertainties allowing for an objective assessment of the industrial robot errors carried out with Renishaw the kinematic telescopic bar.

  18. Inaccuracy of age assessment from images of postpubescent subjects in cases of alleged child pornography.

    Rosenbloom, Arlan L

    2013-03-01

    Despite frequent medical expert testimony authoritatively stating that images of individuals who are postpubescent indicate age less than 18 and therefore, child pornography, developmental experts have noted that a scientific basis for such estimation is lacking. In fact, recent studies have demonstrated a high degree of inaccuracy in such estimates, and that the stage of breast development often used as indicative of age under 18 years is present in a substantial percentage of adult women. Ten images of adult women from legitimate pornographic sites promoting youthful images were shown to 16 pediatric endocrinologists expert in evaluating maturation, who determined whether or not the individuals represented were under 18 years of age. They also provided information about what features were most important in their evaluations. Sixty-nine percent of the 160 estimates were that the images represented females under 18 years of age. There was wide variability in the designation of importance of the various features of maturation in reaching conclusions, with breast development and facial appearance considered most important. This study confirms that medical testimony, even by experts in adolescent development, can deem images of adult women selected for their youthful appearance to be under age 18 two thirds of the time. Thus, important as prosecuting users of child pornographic material may be, justice requires the avoidance of testimony that is not scientifically based.

  19. Influence of inaccuracy of certain parameters on dose distribution in telecobalt therapy

    1975-01-01

    The role of the angle of incidence on the actual distribution of doses and the inaccuracy of certain parameters recorded during preparation for the therapy or shown during successive irradiation courses are studied. Only errors which can be easily quantified are retained. These are errors concerning the irradiation apparatus (source to skin distance, angle of the rays, field dimension) and those due to factors related to the patient treated: contour measurement, entrance point of rays and positional changes of the patient. The different errors can be associated in various ways for a given therapy protocol. For the same reason, an isodose of a given nominal value will have several curves. All these tracings are lined by two curves which are called ''superior and inferior envelopes'': these border the ''incertitude area''. It can be said that at the end of the treatment, the given isodose lies in this area, it is however impossible to define its form or exact position. A few examples in the text illustrate these results and show the possible practical angles of incidence. If errors during successive irradiations are distributed at random, a certain compensation is noted and the ''areas of incertitude'' decrease. But if the errors are constantly on the same side, as is sometimes the case, the dose distribution can be very different from that predicted in the dosimetric protocol [fr

  20. A compensation strategy for geometric inaccuracies of hot incrementally formed parts

    Science.gov (United States)

    Thyssen, Lars; Störkle, Denis D.; Kuhlenkötter, Bernd

    2017-10-01

    The incremental sheet forming (ISF) offers high geometrical form flexibility without the need of any part-dependent tools. However, the industrial application of incremental sheet metal forming is still limited by certain constraints, e.g. the low geometrical accuracy and the small number of formable alloys. One method to overcome the stated constraints is to use the advantages of metal forming at elevated temperatures. Literature shows the benefits of hot forming, e.g. to decrease the resulting forming forces, to increase the number of formable materials, and to enlarge the achievable deformation, but also the negative effects of forming at elevated temperatures. One of those negative effects is that hot formed parts tend to be smaller than parts which have been formed at room temperature. The paper presents a new approach to compensate the resulting inaccuracies of hot formed parts. More precisely, an online compensation strategy is presented which continuously calculates the present part deviation for each point of the tool path according to the actual process parameters and which adds a movement in the opposite direction of the deviation.

  17. The inaccuracy of heat transfer characteristics of insulated and non-insulated circular duct while neglecting the influence of heat radiation

    International Nuclear Information System (INIS)

    Hsien, T.-L.; Wong, K.-L.; Yu, S.-J.

    2009-01-01

    The non-insulated and insulated ducts are commonly applied in the industries and various buildings, because the heat radiation equation contains the 4th order exponential of temperature which is very complicate in calculations. Most heat transfer experts recognized from their own experiences that the heat radiation effect can be ignored due to the small temperature difference between insulated and non-insulated surface and surroundings. This paper studies in detail to check the inaccuracies of heat transfer characteristics non-insulated and insulated duct by comparing the results between considering and neglecting heat radiation effect. It is found that neglecting the heat radiation effect is likely to produce large errors of non-insulated and thin-insulated ducts in situations of ambient air with low external convection heat coefficients and larger surface emissivity, especially while the ambient air temperature is different from that of surroundings and greater internal fluid convection coefficients. It is also found in this paper that using greater duct surface emissivity can greatly improve the heat exchanger effect and using smaller insulated surface emissivity can obtain better insulation.

The method involves polishing or otherwise figuring the multilayer coating that has been deposited on an optical substrate, in order to correct for errors in the figure of the substrate and coating. A method such as ion-beam milling is used to remove material from the multilayer coating by an amount that varies in a specified way across the substrate. The phase of the EUV light that is reflected from the multilayer will be affected by the amount of multilayer material removed, but this effect will be reduced by a factor of 1-n as compared with height variations of the substrate, where n is the average refractive index of the multilayer.

    Background: To interpret blood pressure (BP) data appropriately, healthcare providers need to be knowledgeable of the factors that can potentially impact the accuracy of BP measurement and contribute to variability between measurements. Methods: A systematic review of studies quantifying BP measurement inaccuracy. Medline and CINAHL databases were searched for empirical articles and systematic reviews published up to June 2015. Empirical articles were included if they reported a study that was relevant to the measurement of adult patients’ resting BP at the upper arm in a clinical setting (e.g. ward or office); identified a specific source of inaccuracy; and quantified its effect. Reference lists and reviews were searched for additional articles. Results: A total of 328 empirical studies were included. They investigated 29 potential sources of inaccuracy, categorized as relating to the patient, device, procedure or observer. Significant directional effects were found for 27; however, for some, the effects were inconsistent in direction. Compared with true resting BP, significant effects of individual sources ranged from −23.6 to +33 mmHg SBP and −14 to +23 mmHg DBP. Conclusion: A single BP value outside the expected range should be interpreted with caution and not taken as a definitive indicator of clinical deterioration. Where a measurement is abnormally high or low, further measurements should be taken and averaged. Wherever possible, BP values should be recorded graphically within ranges. This may reduce the impact of sources of inaccuracy and reduce the scope for misinterpretations based on small, likely erroneous or misleading, changes. PMID:27977471

    2007-07-01

    Full Text Available Abstract Background The completion of the Plasmodium falciparum genome represents a milestone in malaria research. The genome sequence allows for the development of genome-wide approaches such as microarray and proteomics that will greatly facilitate our understanding of the parasite biology and accelerate new drug and vaccine development. Designing and application of these genome-wide assays, however, requires accurate information on gene prediction and genome annotation. Unfortunately, the genes in the parasite genome databases were mostly identified using computer software that could make some erroneous predictions. Results We aimed to obtain cDNA sequences to examine the accuracy of gene prediction in silico. We constructed cDNA libraries from mixed blood stages of P. falciparum parasite using the SMART cDNA library construction technique and generated 17332 high-quality expressed sequence tags (EST, including 2198 from primer-walking experiments. Assembly of our sequence tags produced 2548 contigs and 2671 singletons versus 5220 contigs and 5910 singletons when our EST were assembled with EST in public databases. Comparison of all the assembled EST/contigs with predicted CDS and genomic sequences in the PlasmoDB database identified 356 genes with predicted coding sequences fully covered by EST, including 85 genes (23.6% with introns incorrectly predicted. Careful automatic software and manual alignments found an additional 308 genes that have introns different from those predicted, with 152 new introns discovered and 182 introns with sizes or locations different from those predicted. Alternative spliced and antisense transcripts were also detected. Matching cDNA to predicted genes also revealed silent chromosomal regions, mostly at subtelomere regions. Conclusion Our data indicated that approximately 24% of the genes in the current databases were predicted incorrectly, although some of these inaccuracies could represent alternatively

  3. About errors, inaccuracies and sterotypes: Mistakes in media coverage - and how to reduce them

    Scherzler, D.

    2010-12-01

    The main complaint made by scientists about the work of journalists is that there are mistakes and inaccuracies in TV programmes, radio or the print media. This seems to be an important reason why too few researchers want to deal with journalists. Such scientists regularly discover omissions, errors, exaggerations, distortions, stereotypes and sensationalism in the media. Surveys carried out on so-called accuracy research seem to concede this point as well. Errors frequently occur in journalism, and it is the task of the editorial offices to work very hard in order to keep the number of errors as low as possible. On closer inspection some errors, however, turn out to be simplifications and omissions. Both are obligatory in journalism and do not automatically cause factual errors. This paper examines the different kinds of mistakes and misleading information that scientists observe in the mass media. By giving a view from inside the mass media it tries to explain how errors come to exist in the journalist’s working routines. It outlines that the criteria of journalistic quality which scientists and science journalists apply differ substantially. The expectation of many scientists is that good science journalism passes on their results to the public in as “unadulterated” a form as possible. The author suggests, however, that quality criteria for journalism cannot be derived from how true to detail and how comprehensively it reports on science, nor to what extent the journalistic presentation is “correct” in the eyes of the researcher. The paper suggests in its main part that scientists who are contacted or interviewed by the mass media should not accept that errors just happen. On the contrary, they can do a lot to help preventing mistakes that might occur in the journalistic product. The author proposes several strategies how scientists and press information officers could identify possible errors, stereotypes and exaggeration by journalists in advance and

  4. Retorical figures in advertising language

    2012-01-01

    Full Text Available Promotional activities are very often based on advertising and diverse types of public relations. In order to attract consumers' attention and achieve communication goals set by the corporate strategy, advertisers frequently use rhetorical elements in advertising discourse. The advertisers try to convey a desired message and to communicate with the recipient of the message by using various rhetorical figures. It is argued that understanding the structure and function of rhetorical figures in advertising requires a "text- and reader-aware approach". The use of rhetorical figures in advertising has been overlooked in consumer research. This paper shows that the use of rhetorical elements in the advertising discourse is very frequent, but at the same time it is questioned if the function of the rhetorical figures is just a communication with the target market (which is a base of communication models and if the consequences of linguistic influences are much more serious. The complex nature of advertising language with various rhetorical figures (thropes and schemes do not just stimulate recipients to demonstrate a desirable behavior, but indirectly it constructs a concept of desirable lifestyle and it induces them to identify themselves with the explained model. Moreover, the analyzed corpus included advertising slogans of social responsible companies as well as advertising campaigns with elements of diverse ideologies. In the time of digitization and a rapid information flow, consumer's attention is less dedicated to the advertising messages. Therefore, it should be expected that in the future advertisers will have to adjust linguistic, audio and visual techniques to the unfocused message recipients.

  5. Fast figuring of large optics by reactive atom plasma

    The next generation of ground-based astronomical observatories will require fabrication and maintenance of extremely large segmented mirrors tens of meters in diameter. At present, the large production of segments required by projects like E-ELT and TMT poses time frames and costs feasibility questions. This is principally due to a bottleneck stage in the optical fabrication chain: the final figuring step. State-of-the-art figure correction techniques, so far, have failed to meet the needs of the astronomical community for mass production of large, ultra-precise optical surfaces. In this context, Reactive Atom Plasma (RAP) is proposed as a candidate figuring process that combines nanometer level accuracy with high material removal rates. RAP is a form of plasma enhanced chemical etching at atmospheric pressure based on Inductively Coupled Plasma technology. The rapid figuring capability of the RAP process has already been proven on medium sized optical surfaces made of silicon based materials. In this paper, the figure correction of a 3 meters radius of curvature, 400 mm diameter spherical ULE mirror is presented. This work demonstrates the large scale figuring capability of the Reactive Atom Plasma process. The figuring is carried out by applying an in-house developed procedure that promotes rapid convergence. A 2.3 μm p-v initial figure error is removed within three iterations, for a total processing time of 2.5 hours. The same surface is then re-polished and the residual error corrected again down to λ/20 nm rms. These results highlight the possibility of figuring a metre-class mirror in about ten hours.

  7. Algorithm for ion beam figuring of low-gradient mirrors.

    Science.gov (United States)

    Jiao, Changjun; Li, Shengyi; Xie, Xuhui

    2009-07-20

    Ion beam figuring technology for low-gradient mirrors is discussed. Ion beam figuring is a noncontact machining technique in which a beam of high-energy ions is directed toward a target workpiece to remove material in a predetermined and controlled fashion. Owing to this noncontact mode of material removal, problems associated with tool wear and edge effects, which are common in conventional contact polishing processes, are avoided. Based on the Bayesian principle, an iterative dwell time algorithm for planar mirrors is deduced from the computer-controlled optical surfacing (CCOS) principle. With the properties of the removal function, the shaping process of low-gradient mirrors can be approximated by the linear model for planar mirrors. With these discussions, the error surface figuring technology for low-gradient mirrors with a linear path is set up. With the near-Gaussian property of the removal function, the figuring process with a spiral path can be described by the conventional linear CCOS principle, and a Bayesian-based iterative algorithm can be used to deconvolute the dwell time. Moreover, the selection criterion of the spiral parameter is given. Ion beam figuring technology with a spiral scan path based on these methods can be used to figure mirrors with non-axis-symmetrical errors. Experiments on SiC chemical vapor deposition planar and Zerodur paraboloid samples are made, and the final surface errors are all below 1/100 lambda.

  9. Hooke's figurations: a figural drawing attributed to Robert Hooke.

    Science.gov (United States)

    Hunter, Matthew C

    2010-09-20

    The experimental philosopher Robert Hooke (1635-1703) is known to have apprenticed to the leading painter Peter Lely on his first arrival in London in the late 1640s. Yet the relevance of Hooke's artistic training to his mature draughtsmanship and identity has remained unclear. Shedding light on that larger interpretive problem, this article argues for the attribution to Hooke of a figural drawing now in Tate Britain (T10678). This attributed drawing is especially interesting because it depicts human subjects and bears Hooke's name functioning as an artistic signature, both highly unusual features for his draughtsmanship. From evidence of how this drawing was collected and physically placed alongside images by leading artists in the early eighteenth century, I suggest how it can offer new insight into the reception of Hooke and his graphic work in the early Enlightenment.

    1992-01-01

    New developments in optical measurement techniques have made it possible to test the surface quality on grazing incidence optics with extreme precision and accuracy. An instrument developed at Brookhaven, the Long Trace Profiler (LTP), measures the figure of large (up to 1 m long) cylindrical aspheres with nanometer accuracy. The LTP optical system is based around a common-path interferometer design belonging to the class of slope measuring interferometers and, as such, it is very robust, stable, and vibration insensitive. A unique error correction technique removes the effect of tilt errors in the optical head as it traverses the air bearing, thus allowing one to accurately measure the absolute surface profile and radius of curvature. This is of critical importance to the manufacture of long-radius spherical optics used in high-resolution soft x-ray monochromators and in the testing of mirror bending systems. This talk will review the principle of operation of the LTP, probe the factors limiting the performance of the system, and will examine the current state of the art in synchrotron radiation mirror manufacturing quality (as viewed by our metrology techniques).

    2017-11-01

    Optical and structural elements made of silicon carbide are increasingly found in space instruments. Chemical vapor deposited silicon carbide (CVD-SiC) is used as a reflective coating on SiC optics in reason of its good behavior under polishing. The advantage of applying ion beam figuring (IBF) to CVD-SiC over other surface figure-improving techniques is discussed herein. The results of an IBF sequence performed at the Centre Spatial de Liège on a 100 mm CVD-SiC mirror are reported. The process allowed to reduce the mirror surface errors from 243 nm to 13 nm rms . Beside the surface figure, roughness is another critical feature to consider in order to preserve the optical quality of CVD-SiC . Thus, experiments focusing on the evolution of roughness were performed in various ion beam etching conditions. The roughness of samples etched at different depths down to 3 ≠m was determined with an optical profilometer. These measurements emphasize the importance of selecting the right combination of gas and beam energy to keep roughness at a low level. Kaufman-type ion sources are generally used to perform IBF but the performance of an end-Hall ion source in figuring CVD-SiC mirrors was also evaluated in this study. In order to do so, ion beam etching profiles obtained with the end-Hall source on CVD-SiC were measured and used as a basis for IBF simulations.

    We are developing grazing incidence x-ray optics for a balloon-borne hard-x-ray telescope (HERO). The HERO mirror shells are fabricated using electroform-nickel replication off super-polished cylindrical mandrels. One of the sources for mirror resolution error is departure of the shell figure from prescription. We have modified a Vertical-scan Long Trace Profilometer (VLTP) in order to measure the figure of the inner surface of the HERO mirror shells for diameters as small as 76 mm. Mirror alignment method and sources for systematic errors will be discussed. Comparison of figure metrology of the mandrel and the shells will be presented together with results from x-ray tests.

  15. The latest figures on uranium

    2010-01-01

    According to the latest figures on uranium, soon to be published by the NEA, uranium resources, production and demand are all on the rise. Exploration efforts have increased recently in line with the expected expansion of nuclear energy in the coming years. Total identified resources have grown and are now sufficient to cover 100 years of supply at 2008 rates of consumption. Costs of production have, however, also increased. This article is based on the latest edition of the 'Red Book', Uranium 2009: Resources, Production and Demand, which presents the results of the most recent biennial review of world uranium market fundamentals and a statistical profile of the world uranium industry as of 1 January 2009. It contains official data provided by OECD Nuclear Energy Agency (NEA) and International Atomic Energy Agency (IAEA) member countries on uranium exploration, resources, production and reactor-related requirements. Projections of nuclear generating capacity and reactor-related uranium requirements through 2035 are also provided as well as a discussion of long-term uranium supply and demand issues. Despite recent declines stemming from the global financial crisis, world demand for electricity is expected to continue to grow significantly over the next several decades to meet the needs of an increasing population and economic growth. The recognition by an increasing number of governments that nuclear power can produce competitively priced, base-load electricity that is essentially free of greenhouse gas emissions, coupled with the role that nuclear can play in enhancing security of energy supply, increases the prospects for growth in nuclear generating capacity, although the magnitude of that growth remains to be determined. Regardless of the role that nuclear energy ultimately plays in meeting rising electricity demand, the uranium resource base is more than adequate to meet projected requirements. Meeting even high-case requirements to 2035 would consume less

  16. Multiple possible inaccuracies cast doubt on a recent report suggesting selective serotonin reuptake inhibitors to be toxic and ineffective.

    2017-07-18

    According to a systematic review on the use of selective serotonin reuptake inhibitors (SSRIs) in adult depression that was recently published in BMC Psychiatry, the results of which have been widely disseminated in lay media, these drugs increase the risk for serious adverse events (SAEs) while exerting poor antidepressant efficacy. A cursory analysis, however, suggests the analysis of SAEs conducted by the authors to be marred by both methodological inaccuracies and blatant errors. After having corrected for these apparent mistakes, we conducted a sensitivity analysis in which we also accounted for a possible moderating effect of age; while this suggests SSRIs to be safe drugs in the non-elderly, they do confirm what is already known, that is, that they may enhance the risk for SAEs in the old. Given the loose definition of SAE, including also innocuous phenomena, the possible clinical significance of the latter observation, however, remains unclear until the nature and actual impact of the SAEs in question have been clarified. Moreover, with respect to efficacy, we find the paper in BMC Psychiatry misleading: first, the authors seem unaware of the well-established shortcomings associated with the conventional efficacy parameter on which their analysis is based, second, they have included suboptimal SSRI doses and third, they have missed some pivotal trials. Unless there are explanations for the many peculiarities in this paper that have escaped us, and which may be satisfactorily clarified by the authors, it seems important that the conclusions presented in this paper be publicly rectified.

By themselves, these figures are nearly always incomprehensible to both humans and machines and their associated texts are therefore essential for full comprehension. The associated text of a figure, however, is scattered throughout its full-text article and contains redundant information content. In this paper, we report the continued development and evaluation of several figure summarization systems, the FigSum+ systems, that automatically identify associated texts, remove redundant information, and generate a text summary for every figure in an article. Using a set of 94 annotated figures selected from 19 different journals, we conducted an intrinsic evaluation of FigSum+. We evaluate the performance by precision, recall, F1, and ROUGE scores. The best FigSum+ system is based on an unsupervised method, achieving F1 score of 0.66 and ROUGE-1 score of 0.97.

First one called shapely is formed eight open ended question which has concepts and figure. Second one called shapeless is formed eight open ended question which has only concepts. To prepare this data collection tools’ difficulty level we took two math teachers’ opinions. Developed data collection tools were applied 120 students at 9th grade and 11th grade in Trabzon Gazi Anatolian High School. First of all we applied shapeless questions. One month later we applied shapely questions. We investigated students’ answer and the data showed that students more succeed in shapely questions than shapeless questions. We concluded that the difficulty of solving shapeless question result from students didn’t manage to draw figure representing concept knowledge or draw wrong figure, figure drawn by students can’t fulfıl generalizability condition and students who have little knowledge of concept in geometry is under the influence of prototype figure.Key Words:    Figural concepts theory, geometrical reasoning, geometry teaching

    Full Text Available Viewers of Renaissance representations of the Annunciation miss an important irony. Where Mary is figured as unimpressed by Gabriel's proposal, she is upholding a masculinist ideal of female virtue. Where she is figured as delighted by the news, she represents an alternative feminine ideal that continues to be attractive to women and feminists, today. Inspired by the writings of Luce Irigaray and Julia Kristeva, I figure Mary in Renaissance representations of the Annunciation as contesting an ideal of feminine virtue that would deny her sexual difference and deny her pleasure in fulfilling her role as the bride and mother of God.

  9. Feed-forward segmentation of figure-ground and assignment of border-ownership.

    Directory of Open Access Journals (Sweden)

    Hans Supèr

    Full Text Available Figure-ground is the segmentation of visual information into objects and their surrounding backgrounds. Two main processes herein are boundary assignment and surface segregation, which rely on the integration of global scene information. Recurrent processing either by intrinsic horizontal connections that connect surrounding neurons or by feedback projections from higher visual areas provide such information, and are considered to be the neural substrate for figure-ground segmentation. On the contrary, a role of feedforward projections in figure-ground segmentation is unknown. To have a better understanding of a role of feedforward connections in figure-ground organization, we constructed a feedforward spiking model using a biologically plausible neuron model. By means of surround inhibition our simple 3-layered model performs figure-ground segmentation and one-sided border-ownership coding. We propose that the visual system uses feed forward suppression for figure-ground segmentation and border-ownership assignment.

  12. Figure and finish characterization of high performance metal mirrors

    International Nuclear Information System (INIS)

    Takacs, P.Z.; Church, E.L.

    1991-10-01

    Most metal mirrors currently used in synchrotron radiation (SR) beam lines to reflect soft x-rays are made of electroless nickel plate on an aluminum substrate. This material combination has allowed optical designers to incorporate exotic cylindrical aspheres into grazing incidence x-ray beam-handling systems by taking advantage of single-point diamond machining techniques. But the promise of high-quality electroless nickel surfaces has generally exceeded the performance. We will examine the evolution of electroless nickel surfaces through a study of the quality of mirrors delivered for use at the National Synchrotron Light Source over the past seven years. We have developed techniques to assess surface quality based on the measurement of surface roughness and figure errors with optical profiling instruments. It is instructive to see how the quality of the surface is related to the complexity of the machine operations required to produce it

  13. Presenting Fake Figures: A Tool to Teach Effective Scientific Figure Design

    Directory of Open Access Journals (Sweden)

    2013-08-01

    Full Text Available As trained scientists, we become adept not only at analyzing and understanding figures in the scientific literature, but also at designing figures to effectively represent our own data and findings. As educators, we strive to pass on these skills to our students, some of whom will ultimately become scientists themselves. Conveying the principles of effective figure design can be challenging, particularly when students have had little exposure to the process of reading scientific literature, much less writing a piece of scientific literature. Improvisational activities in the classroom reinforce teaching goals such as spontaneity, risk-taking, creativity, communication skills, team-building, and critical thinking (2. Indeed, improv training for scientists is becoming more common, helping scientists to communicate more spontaneously about their work and connect with their audience (1. In this article, we present an improvisational game that can aid in the teaching of effective scientific figure design. This “Present-a-Fake-Figure Exercise” is applicable to both the classroom and laboratory settings. In this learning activity, students improvise presenting fake scientific figures to an audience of their peers. These fake figures are prepared beforehand by the instructor and exemplify the do’s and don’ts of scientific figure design. Some of the learning outcomes of the activity include (1 identifying what makes a scientific figure cohesive, easy to analyze, and reader-friendly, and (2 identifying strategies that are useful in the design of a multi-panel figure to convey a scientific story.

  14. Performance Analysis of Measurement Inaccuracies of IMU/GPS on Airborne Repeat-pass Interferometric SAR in the Presence of Squint

    Full Text Available In the MOtion COmpensation (MOCO approach to airborne repeat-pass interferometric Synthetic Aperture Radar (SAR based on motion measurement data, the measurement inaccuracies of Inertial Measurement Unit/Global Positioning System (IMU/GPS and the positioning errors of the target, which may contribute to the residual uncompensated motion errors, affect the imaging result and interferometric measurement. Considering the effects of the two types of error, this paper builds a mathematical model of residual motion errors in presence of squint, and analyzes the effects on the residual motion errors induced by the measurement inaccuracies of IMU/GPS and the positioning errors of the target. In particular, the effects of various measurement inaccuracies of IMU/GPS on interferometric SAR image quality, interferometric phase, and digital elevation model precision are disscussed. Moreover, the paper quantitatively researches the effects of residual motion errors on airborne repeat-pass interferometric SAR through theoretical and simulated analyses and provides theoretical bases for system design and signal processing.

  15. Figure reversals and creativity: a research note.

    Science.gov (United States)

    Simpson, M T; Lansky, L M; Senter, R J; Peterson, J M

    1983-10-01

    In a series of studies, Bergum and Bergum (1979a, 1979b) noted a positive relationship between college students' self-perceptions of creativity and their passive rates of ambiguous figure reversal. While these authors suggest that a relationship may also exist between figure-reversal rate and creativity, as assessed by external measures, their research does not support this claim. Indeed, other research has not substantiated a relationship between rate of figure reversal and objective tests of creativity (Bloomberg, 1971; Bergum & Flamm, 1975). It may also be the case that students' perceptions of their own creative ability differ markedly from externally-derived measures of such ability. As part of a larger study relating figure-reversal rate, creativity, and handedness, the present authors attempted to replicate and extend the work of Bergum and Bergum through the use of professors' judgments of students' creativity. The subjects were 48 senior students of architecture (40 males, 8 females). Each student initially read a description of six factors commonly associated with creativity in the psychological literature and then rated himself in creative ability in comparison to his classmates. In accordance with Bergum and Bergum (1979a, 1979b), the students passively viewed (and recorded) figure reversals of six ambiguous figures. The six figures were presented for 60 sec. each, with 10-sec. intervals, in two random orders. Students' creative ability was also determined from rankings by two architecture professors who were familiar with the students' work. To guide their rankings, the professors used the same description of creativity as was given to the students.(ABSTRACT TRUNCATED AT 250 WORDS)

  16. The Possibility of Semantic Features and Analysis of Figures of Speech——Cognitive Figures and Expressive Figures

    Directory of Open Access Journals (Sweden)

    2007-10-01

    Full Text Available In this paper, linguistic methodology is suggested for approaching figures of speech formed due to shift of cognitive relations. First, requisite features, possible features and impossible features are proposed on the basis of semantic analysis and their interrelationships and expressions are discussed. Then it is further argued that all figures formed due to shift of cognitive relation are expressed to accept an impossible feature; and there are four semantic forms to accept it: “zero distance/distanced”, “implicit/explicit”, “direct/indirect”, “positive/negative”. Finally, starting from the two approaches to figures we comment on the traditional idea of separating decoration and substance and the new idea of “function as form”.

  20. BOOK REVIEW: Relativistic Figures of Equilibrium

    Science.gov (United States)

    Mars, M.

    2009-08-01

    Compact fluid bodies in equilibrium under its own gravitational field are abundant in the Universe and a proper treatment of them can only be carried out using the full theory of General Relativity. The problem is of enormous complexity as it involves two very different regimes, namely the interior and the exterior of the fluid, coupled through the surface of the body. This problem is very challenging both from a purely theoretical point of view, as well as regarding the obtaining of realistic models and the description of their physical properties. It is therefore an excellent piece of news that the book 'Relativistic Figures of Equilibrium' by R Meinel, M Ansorg, A Kleinwächter, G Neugebauer and D Petroff has been recently published. This book approaches the topic in depth and its contents will be of interest to a wide range of scientists working on gravitation, including theoreticians in general relativity, mathematical physicists, astrophysicists and numerical relativists. This is an advanced book that intends to present some of the present-day results on this topic. The most basic results are presented rather succinctly, and without going into the details, of their derivations. Although primarily not intended to serve as a textbook, the presentation is nevertheless self-contained and can therefore be of interest both for experts on the field as well as for anybody wishing to learn more about rotating self-gravitating compact bodies in equilibrium. It should be remarked, however, that this book makes a rather strong selection of topics and concentrates fundamentally on presenting the main results obtained by the authors during their research in this field. The book starts with a chapter where the fundamental aspects of rotating fluids in equilibrium, including its thermodynamic properties, are summarized. Of particular interest are the so-called mass-shedding limit, which is the limit where the body is rotating so fast that it is on the verge of starting

  6. INFORMATIONAL MODEL OF MENTAL ROTATION OF FIGURES

    2016-01-01

    Full Text Available Subject of Study.The subject of research is the information structure of objects internal representations and operations over them, used by man to solve the problem of mental rotation of figures. To analyze this informational structure we considered not only classical dependencies of the correct answers on the angle of rotation, but also the other dependencies obtained recently in cognitive psychology. Method.The language of technical computing Matlab R2010b was used for developing information model of the mental rotation of figures. Such model parameters as the number of bits in the internal representation, an error probability in a single bit, discrete rotation angle, comparison threshold, and the degree of difference during rotation can be changed. Main Results.The model reproduces qualitatively such psychological dependencies as the linear increase of time of correct answers and the number of errors on the angle of rotation for identical figures, "flat" dependence of the time of correct answers and the number of errors on the angle of rotation for mirror-like figures. The simulation results suggest that mental rotation is an iterative process of finding a match between the two figures, each step of which can lead to a significant distortion of the internal representation of the stored objects. Matching is carried out within the internal representations that have no high invariance to rotation angle. Practical Significance.The results may be useful for understanding the role of learning (including the learning with a teacher in the development of effective information representation and operations on them in artificial intelligence systems.

    We demonstrate that thermoelectric properties of graphene nanoribbons can be dramatically improved by introducing nanopores. In monolayer graphene, this increases the electronic thermoelectric figure of merit ZT e from 0.01 to 0.5. The largest values of ZT e are found when a nanopore is introduced into bilayer graphene, such that the current flows from one layer to the other via the inner surface of the pore, for which values as high as ZT e = 2.45 are obtained. All thermoelectric properties can be further enhanced by tuning the Fermi energy of the leads.

    2012-03-01

    Most patients are decisionally incapacitated at the end of life, leaving final treatment decisions to proxies, whose substituted judgment is often inaccurate. We investigated the reluctance to burden others (RBO), a commonly cited patient value, as a possible source of proxy inaccuracy. In a sample of 202 elders and their proxies, elders responded to three burden-related questions and the Life-prolonging Treatment Preferences Questionnaire. Proxies used substituted judgment to respond to the same questions. Although RBO predicted treatment preferences for both elders and proxies, elders rated RBO significantly more important than did proxies. In addition, larger elder-proxy differences in RBO were associated with more inaccurate substituted judgment.

    2015-01-01

    This book addresses the mathematical rationality contained in the making of string figures. It does so by using interdisciplinary methods borrowed from anthropology, mathematics, history and philosophy of mathematics. The practice of string figure-making has long been carried out in many societies, and particularly in those of oral tradition. It consists in applying a succession of operations to a string (knotted into a loop), mostly using the fingers and sometimes the feet, the wrists or the mouth. This succession of operations is intended to generate a final figure. The book explores differ

    2008-09-01

    Full Text Available Figure skating is a physically demanding sport that requires a unique combination of artistic ability, speed, agility, flexibility and power. During the last decades not only the competitive schedule has become tougher, but after introduction of the new judging system in 2003, also more emphasis is put on difficult technical elements, jumps, steps and spins (ISU Rules, 2006. More studies about possible increasing prevalence of stress fractures in figure skaters and contributing factors are lacking (Dubravcic-Simunjak et al., 2003; Moran, 2000; Pecina et al., 1990. Therefore the aim of this study was to obtain data about the current stress fracture cumulative risk among elite junior and senior figure skaters, as well as possible factors that may contribute to stress fracture incidence. An anonymous questionnaire, divided into 5 sections, inquired about the prevalence of stress fracture were mailed and distributed to all 62 International Skating Union (ISU members by the ISU headquarters in Lausanne, Switzerland. The guidelines of the Helsinki declaration 2004 were followed. From the 644 skaters who received the questionnaire, 412 completed ones were returned from 110 female juniors (78 single skaters, 12 pair skaters and 20 ice dancers and 135 female seniors (97 single skaters, 16 pair skaters and 22 ice dancers and from 79 male juniors (47 single skaters, 12 pair skaters and 20 ice dancers and 88 male seniors (50 single skaters, 16 pair skaters and 22 ice dancers, coming from different ISU members. The response rate was 62% in females and 67% in males. The median age for female skaters was 16 years and for males 18 years (range 12-25 years. All participants started to skate between 3 and 6 years of age and started to compete in national and international competitions when they were between 5 and 7 years old. At the time of this analysis, they had been skating between 9 and 20 years.In females 41 (16.7%, and in males 25 (13.8% figure skaters

  12. Figuration of tourist personality and tourist travels

    Directory of Open Access Journals (Sweden)

    Đorđević Saša

    2013-01-01

    Full Text Available Quality of tourist travel is a relative category, because its success depends on the subjective perception of the personality of tourists on a tourist trip. For this reason, any tourist trip can be treated from the perspective of different types of figurative forms of tourists' personality, which also determine different quality of tourist travel, which, in turn, makes them different. Thus, any tourist trip, unto itself, has its own uniqueness, taking on the forms and content created, for the most part, by the tourists themselves, along with all other tourism stakeholders involved in this process. These forms and contents are primarily conditioned by the spiritual profile of tourists' personality and their psychological and motivational preferences, which is symbolically represented in the figurative context of a chess game. In addition to this, identification of essential characteristics of different spiritual profiles of tourist's personality, must be a starting point for the programming of overall content and especially of animation and cultural content.

  13. Ambiguous Authorities: Vertigo and the Auteur Figure

    Directory of Open Access Journals (Sweden)

    Isabelle Licari-Guillaume

    2017-12-01

    Full Text Available This article examines authorial performance in the context of DC’s Vertigo line. In the 1990s, Vertigo gained its reputation as an innovative and progressive imprint by promoting the work of British scriptwriters, who were hailed as true author figures, despite the inherently collaborative nature of the mainstream comics industry. In a manner reminiscent of “auteur theory”, writers such as Neil Gaiman, Warren Ellis or Grant Morrison developed attractive author personas which they consistently displayed through interviews, letter columns or social media, but also, more importantly, by inserting their avatars within the comics they scripted. Upon closer examination, however, it becomes clear that their work in fact simultaneously asserts and destabilizes writerly authority, in a manner that is consistent with Linda Hutcheon’s view of postmodernity. By multiplying author figures and playfully disseminating authority, Vertigo authors question their own authorial control over the text, asserting instead the crucial role played by the reader.

  17. Vacuum-Flex Figuring of Primary Telescope Mirrors

    Science.gov (United States)

    Albin, E. F. M.

    2004-12-01

    In the current investigation, details on the construction and performance of a vacuum-flexed (i.e., figured) 51 cm (20-inch) mirror, with a fast f/4 focal ratio, are presented. A vacuum has the chief advantage of being able to pull with a uniform or isotropic stress across a large surface area, which will naturally form a parabolic surface. The essence of the idea is to grind and polish a spherical mirror and then warp or flex it into a near perfect paraboloid, thus avoiding tedious figuring altogether. To date, telescope makers around the globe have experimented with small flexed mirrors with considerable success. In these instances, mirrors have been flexed by exerting tension on a bolt or sponge-pad adhered to the back of the mirror. The prototype mirror consists of two 51 cm disks of plate glass -- each slumped to an f/4 focal ratio. The front-plate (19 mm in thickness) is separated from the back-plate (13 mm in thickness) back a flexible 9.5 mm air filled gasket. Although the rubber gasket makes a fairly good vacuum seal, silicon cement was placed about the outer edge in order to produce a perfectly tight seal. A vacuum of 8 kPa on the back of the mirror resulted in approximately 164 kilograms of negative pressure, which is required to flex the mirror into the required paraboloid. Ronchi test show a nice smooth paraboloid free from astigmatism while foucault zonal measurements display a figure better than 1/20 wave. Preliminary star testing show promising results as well. Vacuum-flexed mirrors may have benefits for both amateur and professional telescope makers alike. A US patent is pending on the aforementioned design.

    The consumption of final energy in France in 2006 increased slightly on the whole (+0.6%) and in all sectors except the industry (-0.7%). The final energy consumption is defined as the difference between the total consumption of primary energy and the consumption of the energy production sector. The evolution of the consumption of final energy is different according to the type of energy: +4.1% for coal (due to the strong demand in the iron and steel industry), +3.6% for renewable energies (due to specific development programs), +1.5% for electrical power and no change for oil and natural gas. Despite high prices, sales of car fuels rose by 0.4%, this figure hides the fact that the sales of fuels for diesel cars rose by 2.7% (because of the growing population of diesel cars) while those of grade petrol kept on plummeting (-5.9%). It is important to note that the releases of CO 2 due to energy went down by -1.4% in 2006. The energy bill increased by +18.5% to fetch 46.2*10 9 euros despite the decrease of the imported volumes. This articles details the energy figures for France in 2006 and sheds light particularly on 3 aspects: first, the annual trends in energy since 1973, secondly, the energy bill and thirdly the figures for electricity, natural gas, solid mineral fuels, hydrocarbons and renewable sources of energy.

  20. Requirement of nuclear data and inaccuracy of nuclear data in evaluating the target values of shielding calculations for the light water reactor and the high-temperature reactor

    International Nuclear Information System (INIS)

    Kicherer, G.; Hehn, G.

    1982-01-01

    This study tries to investigate for the first time systematically and quantitatively the influence on the prediction of reactor shieldings from inaccuracies in nuclear data playing an essential part in design, monitoring, and estimation of the useful life of power reactors. The main objective is to calculate the contribution of the error in nuclear data to the inaccuracy of the targets of reactor shielding calculations expressed in terms of radiation dose, radiation damages and radiation heat, that have got a high safety relevance. As a result, it can be determined if there remains a sufficiently large margin for the errors from the mathematical method and the geometrical approximation. In the first part of the paper the most important international nuclear data libraries are compared by means of a one-dimensional shielding calculation for the BWR KRB II. In the second part a systematic sensitivity study for the shielding targets of a BWR (KRB II/1300 MWsub(el)) and a HTGR (THTR-300/300 MWsub(el)) is performed for the cross-section data of the individual nuclides. In relation with the evaluated nuclear data errors and the result of the sensitivity study the error in the nuclear data used for the prediction of the radiation damage to the RPV or liner respectively and of the radiation dose in the concrete of the primary shield can be analyzed for light water and high-temperature reactors.

  1. Dissociation of color and figure-ground effects in the watercolor illusion.

    Science.gov (United States)

    Von der Heydt, Rüdiger; Pierson, Rachel

    2006-01-01

    Two phenomena can be observed in the watercolor illusion: illusory color spreading and figure-ground organization. We performed experiments to determine whether the figure-ground effect is a consequence of the color illusion or due to an independent mechanism. Subjects were tested with displays consisting of six adjacent compartments--three that generated the illusion alternating with three that served for comparison. In a first set of experiments, the illusory color was measured by finding the matching physical color in the alternate compartments. Figureness (probability of 'figure' responses, 2AFC) of the watercolor compartments was then determined with and without the matching color in the alternate compartments. The color match reduced figureness, but did not abolish it. There was a range of colors in which the watercolor compartments dominated as figures over the alternate compartments although the latter appeared more saturated in color. In another experiment, the effect of tinting alternate compartments was measured in displays without watercolor illusion. Figureness increased with color contrast, but its value at the equivalent contrast fell short of the figureness value obtained for the watercolor pattern. Thus, in both experiments, figureness produced by the watercolor pattern was stronger than expected from the color effect, suggesting independent mechanisms. Considering the neurophysiology, we propose that the color illusion follows from the principles of representation of surface color in the visual cortex, while the figure-ground effect results from two mechanisms of border ownership assignment, one that is sensitive to asymmetric shape of edge profile, the other to consistency of color borders.

  2. The Emergence of Figural Effects in the Watercolor Illusion

    Science.gov (United States)

    Pinna, Baingio; Penna, Maria Pietronilla

    The watercolor illusion is characterized by a large-scale assimilative color spreading (coloration effect) emanating from thin colored edges. The watercolor illusion enhances the figural properties of the colored areas and imparts to the surrounding area the perceptual status of background. This work explores interactions between cortical boundary and surface processes by presenting displays and psychophysical experiments that exhibit new properties of the watercolor illusion. The watercolor illusion is investigated as supporting a new principle of figure-ground organization when pitted against principles of surroundedness, relative orientation, and Prägnanz. The work demonstrated that the watercolor illusion probes a unique combination of visual processes that set it apart from earlier Gestalt principles, and can compete successfully against them. This illusion exemplifies how long-range perceptual effects may be triggered by spatially sparse information. All the main effects are explained by the FACADE model of biological vision, which clarifies how local properties control depthful filling-in of surface lightness and color.

    Full Text Available This three-year study focused on first-year Calculus I students and their abilities to incorporate figures in technical reports. In each year, these calculus students wrote a technical report as part of the Polar Bear Module, an educational unit developed for use in partner courses in biology, computer science, mathematics, and physics as part of the Multidisciplinary Sustainability Education (MSE project at Ithaca College. In the first year of the project, students received basic technical report guidelines. In year two, the report guidelines changed to include explicit language on how to incorporate figures. In year three, a grading rubric was added to the materials provided to one of the two classes. In all three years, the students performed below expectations in their use of graphs in their reports. Reviews of the figures in the 78 technical reports written by the 106 students showed repeated deficiencies in the figures and how the students used them in the discussion sections and in evidence-based arguments. In year three the student’s quantitative literacy (QL skills were assessed using an extract from a QL assessment instrument published in Numeracy. The results indicated that the students could both read and interpret figures, suggesting that issues with QL were not the main contributor to student difficulty with written discussion about graphs. The study underscores the need that explicit instructional attention be given to developing student knowhow in the use of figures in technical reports.

  5. The inaccuracy of heat transfer characteristics for non-insulated and insulated spherical containers neglecting the influence of heat radiation

    2011-01-01

    In this investigation, the differences of heat transfer characteristics for insulated and non-insulated spherical containers between considering and neglecting the influence of heat radiation are studied by the simulations in some practical situations. It is found that the heat radiation effect cannot be ignored in conditions of low ambient convection heat coefficients (such ambient air) and high surface emissivities, especially for the non-insulated and thin insulated cases. In most practical situations when ambient temperature is different from surroundings temperature and the emissivity of insulation surface is different from that of metal wall surface, neglecting heat radiation will result in inaccurate insulation effect and heat transfer errors even with very thick insulation. However, the insulation effect considering heat radiation will only increase a very small amount after some dimensionless insulated thickness (such insulation thickness/radius ≥0.2 in this study), thus such dimensionless insulated thickness can be used as the optimum thickness in practical applications. Meanwhile, wrapping a material with low surface emissivity (such as aluminum foil) around the oxidized metal wall or insulation layer (always with high surface emissivity) can achieve very good insulated effect for the non-insulated or thin insulated containers.

    Is Hitler bigger than Napoleon? Washington bigger than Lincoln? Picasso bigger than Einstein? Quantitative analysts are rapidly finding homes in social and cultural domains, from finance to politics. What about history? In this fascinating book, Steve Skiena and Charles Ward bring quantitative analysis to bear on ranking and comparing historical reputations. They evaluate each person by aggregating the traces of millions of opinions, just as Google ranks webpages. The book includes a technical discussion for readers interested in the details of the methods, but no mathematical or computational background is necessary to understand the rankings or conclusions. Along the way, the authors present the rankings of more than one thousand of history's most significant people in science, politics, entertainment, and all areas of human endeavor. Anyone interested in history or biography can see where their favorite figures place in the grand scheme of things.

    2012-02-01

    Full Text Available Mika Elo is a postdoctoral researcher and lecturer in visual culture at Aalto University School of Arts, Design and Architecture (Aalto-ARTS, Helsinki. His research interests include theory of photographic media, philosophical media theory, and artistic research. He is participating in discussions in these areas in the capacity of curator, visual artist and researcher. He has published articles in Finnish, German, and English among others on Benjamin, Nancy, artistic research and photography theory. His doctoral thesis Valokuvan medium [The Medium of Photography] was published in Finnish in 2005 (Tutkijaliitto, Helsinki. In 2009–2011 he worked in the Figures of Touch research project (figuresoftouch.com, and since 2011 he is the director of Media Aesthetics research group at Aalto-ARTS, Department of Media.Author Biography The article reflects on digitality and interface design in terms of the multiple senses of touch. Touching is presented as a “pathic” sense of being exposed, which implies that touching exceeds the tactile and even the phenomenal world. A particular focus is set on Aristotle's and Husserl's ways of thematizing the sense of touch. In this way, two extremes of the phenomenological thinking of touching are articulated: touching as an indistinct and heterogeneous constituent of sensitivity and touching as the guarantor of immediacy of the sense experience. Referring to Derrida's critical notes concerning haptocentrism, the article attempts to problematize the hand and the finger as phenomenological figures of touch and as holds of haptic realism. The article concludes that insofar as digital interface design aims at haptic realism it conceives of the sense of touch in terms of narcissistic feedback and thus tends to conceal the pathic moment of touching.

  18. Solution algorithm of dwell time in slope-based figuring model

    2017-10-01

    Surface slope profile is commonly used to evaluate X-ray reflective optics, which is used in synchrotron radiation beam. Moreover, the measurement result of measuring instrument for X-ray reflective optics is usually the surface slope profile rather than the surface height profile. To avoid the conversion error, the slope-based figuring model is introduced introduced by processing the X-ray reflective optics based on surface height-based model. However, the pulse iteration method, which can quickly obtain the dell time solution of the traditional height-based figuring model, is not applied to the slope-based figuring model because property of the slope removal function have both positive and negative values and complex asymmetric structure. To overcome this problem, we established the optimal mathematical model for the dwell time solution, By introducing the upper and lower limits of the dwell time and the time gradient constraint. Then we used the constrained least squares algorithm to solve the dwell time in slope-based figuring model. To validate the proposed algorithm, simulations and experiments are conducted. A flat mirror with effective aperture of 80 mm is polished on the ion beam machine. After iterative polishing three times, the surface slope profile error of the workpiece is converged from RMS 5.65 μrad to RMS 1.12 μrad.

    The investigations of the Mars gravitational figure (areoid) on the base of gravitational field models, suggested by Jordan, Born, Rizenberg and Sjegren have been carried out. Level surfaces are determined by the iteration method, suggested by G.A. Mescheryakov. The maps of the Mars areoid surface are built up. Regional peculiarities of the Mars gravitational figure are shortly considered. A close connection of the areoid surface and topographical surface of the planet is shown. Correlation coefficient between radii-vectors of the areoid and the topographical surface equals 0.96. Latitudinal correlation functions of areoid and relief of the Mars coincide; longitudinal ones little differ from them and only with longitude more than 70 deg they begin to diverge

  2. Figure and Ground in the Visual Cortex: V2 Combines Stereoscopic Cues with Gestalt Rules

    Qiu, Fangtu T.; von der Heydt, Rüdiger

    2006-01-01

    Figure-ground organization is a process by which the visual system identifies some image regions as foreground and others as background, inferring three-dimensional (3D) layout from 2D displays. A recent study reported that edge responses of neurons in area V2 are selective for side-of-figure, suggesting that figure-ground organization is encoded in the contour signals (border-ownership coding). Here we show that area V2 combines two strategies of computation, one that exploits binocular stereoscopic information for the definition of local depth order, and another that exploits the global configuration of contours (gestalt factors). These are combined in single neurons so that the ‘near’ side of the preferred 3D edge generally coincides with the preferred side-of-figure in 2D displays. Thus, area V2 represents the borders of 2D figures as edges of surfaces, as if the figures were objects in 3D space. Even in 3D displays gestalt factors influence the responses and can enhance or null the stereoscopic depth information. PMID:15996555

  4. Display-wide influences on figure-ground perception: the case of symmetry.

    Science.gov (United States)

    Mojica, Andrew J; Peterson, Mary A

    2014-05-01

    Past research has demonstrated that convex regions are increasingly likely to be perceived as figures as the number of alternating convex and concave regions in test displays increases. This region-number effect depends on both a small preexisting preference for convex over concave objects and the presence of scene characteristics (i.e., uniform fill) that allow the integration of the concave regions into a background object/surface. These factors work together to enable the percept of convex objects in front of a background. We investigated whether region-number effects generalize to another property, symmetry, whose effectiveness as a figure property has been debated. Observers reported which regions they perceived as figures in black-and-white displays with alternating symmetric/asymmetric regions. In Experiments 1 and 2, the displays had articulated outer borders that preserved the symmetry/asymmetry of the outermost regions. Region-number effects were not observed, although symmetric regions were perceived as figures more often than chance. We hypothesized that the articulated outer borders prevented fitting a background interpretation to the asymmetric regions. In Experiment 3, we used straight-edge framelike outer borders and observed region-number effects for symmetry equivalent to those observed for convexity. These results (1) show that display-wide information affects figure assignment at a border, (2) extend the evidence indicating that the ability to fit background as well as foreground interpretations is critical in figure assignment, (3) reveal that symmetry and convexity are equally effective figure cues and, (4) demonstrate that symmetry serves as a figural property only when it is close to fixation.

It serves various functions in communication, it is used to share ideas, convey feelings and emotions, etc. The researchers are interested to uncover more on how people use language in terms of its variety and lexical in one of the popular social media networking platforms that we all know as Facebook. Based on the aforementioned background of the study, the problem of the research can be formulated as follows: (1 what are the figurative languages used in Facebook posts by female and male Facebook users? (2 How are the emotional lexical varieties e.g. used in Facebook posts? Method of research is a procedure needed to do the research better. In this case, method of research covers data source, data collection and data analysis. The data of this research have been taken from Facebook, it is as an online social networking website where people can create profiles, share information such as photos and quotes about themselves, and respond or link to the information posted by others. The method that used in collecting data is method of library research. They are collected by reading the Facebook user’s post, by underlining and note taking as well. The data analysis is the last step in this process of writing this research. The analysis is done by descriptive method. To make the analysis clearer, all of examples are completed with explanation.

    Full Text Available Layback spin is considered as one of the most beautiful and elegant spins performed in figure skating. It is also one of the required spins in competitive short program in female category. Different techniques of executing layback spin with variations in changing the positions of free parts of the body, as well as the evaluation of layback spin in accordance with ISU rules and regulations, which have been used in all International Skating Federation competitions since 2004 (World and European championships, Olympic Games are presented in this paper. Due to very difficult position of the body while performing a layback spin, it is essential that the skaters who want to master it should have excellent agility (especially of the spinal column and shoulder and knee joints and balance. Layback spin performance requires significant skating knowledge, so it cannot be performed by beginners. Depending on the fl exibility and creativity, a skater can execute various positions of the head, arms, body and free leg while performing a layback spin. In some cases, these variations can increase the level of difficulty, and in others only the mark given for executing this spin.

    Full Text Available The history of midwifery, fairly disregarded by Italian historiography, results crucial in order to fully understand both the role of women and of the foundation of the family in post-unification Italy. It firmly highlights the complexity, the undertones and, sometimes, the contradictions of the female models. The historical research, mainly in the English area, has fully recognized the indisputable significance of the midwives’ role. As a matter of fact, they emerge as representatives of medical professions in the volume by Willem Tousijn, Il sistema delle occupazioni sanitarie (2000, which combines both historical reconstruction and sociological survey. If, on the one hand, the history of midwifery is quite acquainted for the 17th and 18th centuries, thanks to the works by Mireill Laget (1982, and by Jacques Gélis (1988, on the other hand, however, the 19th century still remains to be written for the great part. In Italy, Laura Guidi, Claudia Pancino and Alessandra Gissi have traced an outline of the midwives’ path for their professional achievement throughout the 19th and the 20th centuries. This article briefly reviews these themes, rereading the texts and focusing, in particular, on the question of the professionalization of the midwife and on its actual recognition as a professional figure.

  9. An economics figure of merit in ALPS

    International Nuclear Information System (INIS)

    Shatilla, Y.A.

    2000-01-01

    One of the most pressing issues facing the deregulated nuclear electric power industry is its economic competitiveness when compared to other sources of electrical power. Traditionally, finding the optimum loading pattern (LP) that meets all the safety and operational objective functions and at the same time produces the most attractive economical solutions is an iterative process. This is because (a) LP search tools usually lack the capability to generate equilibrium solutions and (b) economics objective functions are hard to include in the search process. In this paper, the Westinghouse Advanced Loading Pattern Search code (ALPS) has been demonstrated to successfully find LPs that meet user-defined operational and safety as well as economics objectives. This has been made possible by the development of TULIP language that allows the integration of external procedures into the search process of the main program, ALPS. In the example given, an economic figure of merit (EFM) has been defined and included via TULIP script into the fuel management optimization problem of a three-loop Westinghouse core operating an 18-month cycle. The LPs found by ALPS exhibit a clear trend of meeting and, in some cases, exceeding the EFM objective function defined for the ALPS search process a priori

  12. Lighting, backlighting and watercolor illusions and the laws of figurality.

    Science.gov (United States)

    Pinna, Baingio; Reeves, Adam

    2006-01-01

    We report some novel 'lighting' and 'backlighting' effects in plane figures similar to those which induce the 'watercolor illusion', that is, figures made with outlines composed of juxtaposed parallel lines varying in brightness and chromatic color. These new effects show 'illumination' as an emergent percept, and show how arrangements of 'dark and light' along the boundaries of various plane figures model the volume and strengthen the illusion of depth. To account for these various effects we propose several phenomenological 'laws of figurality' to add to the Gestalt laws of organization and figure-ground segregation. We offer a set of meta-laws which are speculative but which serve to integrate and organize the phenomenological laws. These laws indicate how luminance gradient profiles across boundary contours define both the 3D appearance of figures and the properties of the light reflected from their volumetric shapes.

    Creatures in nature possess almost perfect structures and properties, and exhibit harmonization and unification between structure and function. Biomimetics, mimicking nature for engineering solutions, provides a model for the development of functional surfaces with special properties. Recently, honeycomb structure materials have attracted wide attention for both fundamental research and practical applications and have become an increasingly hot research topic. Though progress in the field of breath-figure formation has been reviewed, the advance in the fabrication materials of bio-inspired honeycomb structure films has not been discussed. Here we review the recent progress of honeycomb structure fabrication materials which were prepared by the breath-figure method. The application of breath figures for the generation of all kinds of honeycomb is discussed. PMID:28809319

    We are developing grazing incidence x-ray optics for a balloon-borne hard-x-ray telescope (HERO). The HERO mirror shells are fabricated using electroform-nickel replication off super-polished cylindrical mandrels. One of the sources for mirror resolution error is departure of the shell figure from prescription. We have modified a Vertical-scan Long Trace Profilometer (VLTP) in order to measure the figure of the inner surface of the HERO mirror shells for diameters as small as 74 mm. Metrology of the figure, the microroughness, tilt angle, the circularity for the shell mirrors and the mandrels, as well as alignment procedures are discussed. Comparison of metrology of the mandrel and the shells is presented together with results from x-ray tests.

  17. Determination of the crystallite orientation distribution from direct pole figures

    International Nuclear Information System (INIS)

    Araujo Gomes, P.A.M. de.

    1977-01-01

    A method is described which allows to calculate the crystallite orientation distribution in polycrystalline material, from direct pole figures data of its crystallographic planes (Roe's Method). The programme was applied to (1010), (0002), (1011) and (1120) complete pole figures data for a commercial, thin sheet Zircaloy-4 tubing specimen. A semi-automatic Rigaku-Denki texture goniometer, which scans the reciprocal lattice sphere pointwise outputting the data in a punched tape, was used to obtain the pole figures. This is consistent with the results obtained through direct conclusion from the pole figures. (author)

    Full Text Available Although figures in scientific articles have high information content and concisely communicate many key research findings, they are currently under utilized by literature search and retrieval systems. Many systems ignore figures, and those that do not typically only consider caption text. This study describes and evaluates a fully automated approach for associating figures in the body of a biomedical article with sentences in its abstract. We use supervised methods to learn probabilistic language models, hidden Markov models, and conditional random fields for predicting associations between abstract sentences and figures. Three kinds of evidence are used: text in abstract sentences and figures, relative positions of sentences and figures, and the patterns of sentence/figure associations across an article. Each information source is shown to have predictive value, and models that use all kinds of evidence are more accurate than models that do not. Our most accurate method has an F1-score of 69% on a cross-validation experiment, is competitive with the accuracy of human experts, has significantly better predictive accuracy than state-of-the-art methods and enables users to access figures associated with an abstract sentence with an average of 1.82 fewer mouse clicks. A user evaluation shows that human users find our system beneficial. The system is available at http://FigureItOut.askHERMES.org.

  20. Structural Configuration of Myelin Figures Using Fluorescence Microscopy

    2012-01-01

    Full Text Available Using epifluorescence microscopy, the configuration of myelin figures that are formed upon hydration of lipid stack was studied qualitatively. Little knowledge is currently available for conditions that determine the diameter of myelin figures and their degree of multilamellarity. Examining more than 300 samples, we realized that there are distinct populations of myelin figures protruding from discrete regions of lipid stack. Each population contains myelin figures with similar diameters. This indicates a direct relationship between local characteristics of parent lipid stack and the diameter of myelin figures. Evidenced by fluorescent images, we classified all the observed myelin figures into three major groups of (1 solid tubes, (2 thin tethers, and (3 hollow tubes. Solid tubes are the most common structure of myelin figures which appeared as dense shiny cylinders. Thin tethers, with long hair-shaped structure, were observed protruding from part of lipid plaque which is likely to be under tension. Hollow tubes were protruded from the parts that are unpinned from the substrate and possibly under low or no tension. The abrupt change in the configuration of myelin figures from solid tubes to hollow ones was described in a reproducible experiment where the pinned region of the parent stack became unpinned. Our observations can indicate a relation between the membrane tension of the source material and the diameter of the myelin figures.

  2. The watercolor effect: a new principle of grouping and figure-ground organization.

    Science.gov (United States)

    2003-01-01

    The watercolor effect is perceived when a dark (e.g., purple) contour is flanked by a lighter chromatic contour (e.g., orange). Under these conditions, the lighter color will assimilate over the entire enclosed area. This filling-in determines figure-ground organization when it is pitted against the classical Gestalt factors of proximity, good continuation, closure, symmetry, convexity, as well as amodal completion, and past experience. When it is combined with a given Gestalt factor, the resulting effect on figure-ground organization is stronger than for each factor alone. When the watercolor effect is induced by a dark red edge instead of an orange edge, its figural strength is reduced, but still stronger than without it. Finally, when a uniform surface is filled physically using the color of the orange fringe, figure-ground organization is not different from that for the purple contour only. These findings show that the watercolor effect induced by the edge could be an independent factor, different from the classical Gestalt factors of figure-ground organization.

  3. Inaccuracies in helium isotope measurements

    Science.gov (United States)

    Aruev, N. N.; Boltenkov, B. S.

    2012-08-01

    The results of mass-spectrometric measurements of the helium isotope content in aluminum samples obtained at different times and under different conditions and also of the helium isotope content in iron-manganese concretions are presented. The measurement accuracy of the helium isotope content in aluminum depends on various measuring-technique-related factors: vacuum conditions, gas inleakage and escape in the mass analyzer and/or gas extraction system, the device memory effect as applied to any of the helium isotopes, preparation accuracy of reference samples, their persistence, etc. In the given case, the statistical processing of measurement data with different criteria indicates that the variances diverge considerably but does not discover the sources of divergence. To measure the helium isotope content in iron-manganese concretions, a powdered sample is placed in a metallic capsule, which is then thrown into a heated crucible in vacuum, where gases to be tested liberate. Our statistical analysis of measuring data confirms the supposition that, if the capsule is made of low-melting aluminum and the capsule with a fine powder is thrown into a heated crucible, the variance grows and measuring data are underestimated. This seems to be associated with rapid melting of the capsule, emission of fine particles of the sample out of the hot zone of the reactor, and their loss. When the capsule is made of nickel, a much higher melting material than aluminum, it does not melt and the test material is not ejected from the hot zone. That is what follows from the results of the statistical analysis in our opinion.

  4. Study of ordered macroporous polymer films by templating breath figures

    Song, Lulu

    2005-11-01

    Macroporous films with highly ordered pore patterns have many potential applications. Some examples include microstructured electrode surfaces, photonic band gap materials and filters for cell sorting and bio-interfaces. In this dissertation we discuss a "moist-casting" method to prepare hexagonally-ordered macroporous films with pore sizes in the range of sub-micron to several microns, where condensed water droplets ("breath figures") work as templates. Compared with other templating methods, this one is fast and simple. Well-ordered porous films can be obtained in tens of seconds and the pore size can be easily tailored and dynamically controlled by adjusting the casting conditions. More importantly, there is no need to remove the templates; water droplets just evaporate when the casting processes are finished. This study was carried out with the intention of characterizing the structures, understanding film-formation processes and exploring special properties and possible applications. For the structural characterization, film morphology was studied in detail by normal optical microscopy and laser scanning confocal microscopy (LSCM). Several interesting features have been revealed. Meanwhile, the degree of the order of the porous structures were characterized both in real space via Voronoi diagram and bond-orientational correlation function, and in reciprocal space via Fraunhofer diffraction pattern. To further understand the mechanism, the evaporation of the polymer solutions during the film formation was studied by monitoring their mass over time. Besides, the evolution of breath figures formed on the evaporating polymer solutions was in-situ recorded via a high-speed camera coupled to an optical microscope. Combined with the information on the film structures obtained via LSCM, explanations for some detailed features have been attempted. Wetting property of these films was studied in some detail. The films exhibited "lotus effect", mimicking natural non

  5. Figures and First Years: Examining first-year Calculus I student ability to incorporate figures into technical reports

    Science.gov (United States)

    Antonacci, Nathan; Rogers, Michael; Pfaff, Thomas

    This three-year study focused on first-year Calculus I students and their abilities to incorporate figures into technical reports. Students were handed guidelines as part of their Multidisciplinary Sustainability Education Module meant to aid them in crafting effective figures. Figure-specific questionnaires were added in the class to gain insight into the quantitative literacy skills students possessed both before starting their course and after its completion. Reviews of the figures in 78 technical reports written by 106 students showed repeated failure to refer to figures in discussion sections and use them in evidence-based arguments. Analysis of quantitative literacy skills revealed that the students could both read and interpret figures, suggesting that issues with literacy were not the main contributor to the sub-par graphs.

  6. Blurring the Edges: Ricoeur and Rothko on Metaphorically Figuring the Non-Figural

    Directory of Open Access Journals (Sweden)

    B. Keith Putt

    2017-02-01

    Full Text Available This essay examines Ricœur’s mimetic and transfigurative perspective on non-objective art and adopts it as an idiom for examining Mark Rothko’s artistic intention in the multiform canvases of his “classical” period from 1949 until his death in 1970. Rothko unequivocally denied being an abstractionist, a colorist, or a formalist, insisting, on the contrary, that he desired to communicate discrete dimensions of experience and emotions to his viewers, specifically, experiences of the sacred and the spiritual. His large canvases, with their blurred edges, force the spectator into an intimacy of experience that opens the potentiality of heterogeneous interpretations. In other words, one might consider his paintings to be metaphors of dense meanings that imitate reality, not through facile representation, but through a Kierkegaardian repetition of worlds that track Ricœur’s own ideas of prefiguration, configuration, and re-figuration. I contend in this essay that Rothko’s “abstract expressionism” adequately illustrates Ricœur’s contention that non-figurative art succeeds far better than representational art in refiguring new worlds of meaning.

    2013-09-01

    Innovative freeform optical systems such as head-up displays or LED headlights often require high quality and high volume optics. Injection molded polymer optics offer a cost effective solution. However, mold manufacturing for this process is extremely challenging as the machining of freeform surfaces is currently characterized by several independent production steps which can limit surface accuracy. By integrating diamond turning, milling, and metrology onto a single platform, the UPC 400 improves surface accuracy. Advanced software for machining and measurement data further reduces surface inaccuracies. This combination makes the UPC 400 efficient for prototyping free-form optics and manufacturing high precision molds.

    The figure of Nine Zone and Eight Winds is the only figure in Huangdi Neijing·Taisu. Recording in Lingshu·Jiuzhenlun identifies the origin of the division of the human body circumference. The human body division theory was consistent with archaeological discoveries of Shengui (sacred turtle) divinations and Renzitu (herringbone figure). By matching organs, and body surface with Ba Fang (eight directions), Ba Jie (eight solar terms) and Ba Feng (eight kinds of winds from eight directions), the figure of Nine Zone and Eight Winds connected time, space and human body, and the framework of the theory of the human body formed.

  4. Deviation in the predefined calibration factors of the dose calibrators and the associated inaccuracy in the radioactivity measurements of beta-gamma emitters

    2015-01-01

    To determine whether the predefined calibration factors of the dose calibrators can provide accurate radioactivity measurements of beta-gamma emitters used in routine therapeutic nuclear medicine procedures. Two models of dose calibrators were used in the present study for radioactivity measurements of 153 Sm ethylenediamine-N, N, N’, N’-tetrakis methylene phosphonic acid (EDTMP) and 177 Lu (EDTMP). A known (precalibrated) activity of each of the two beta emitters received by us from our National Supplier for administration to the patients with extensive bony metastases for bone pain palliation, was used for experiments. When we used the manufacturers’ provided dial setting of 450 × 10, each of the dose calibrators underestimated the radioactivity of 177 Lu by about 9.0%. Dial settings of 403 × 10 and 408 × 10 for 177 Lu on CRC-15R and CRC-ultra dose calibrators respectively were calculated experimentally using an iterative approach. The radioactivity measurements made at these settings provided an excellent agreement with the specified values. Likewise, a dial setting of 230 for each of the two dose calibrators was calculated for 153 Sm, which provided a good agreement between the experimentally derived radioactivity values and the certified values. A deviation of ± 5.0% was observed when radioactivity of 177 Lu and 153 Sm was measured over a wide range (4.0 MBq to 2.1 GBq) for time intervals equivalent to 4.5 half-lives of each of the two radionuclides. A deviation of ± 5% was observed when radioactivity was counted in different dilution volumes and in syringes of varying size. These variations could lead to a cumulative error of about 20.0% toward the inaccuracy in the radioactivity measurements of the beta-gamma emitters and thus predefined calibration factors of the dose calibrators may require experimental re-setting of these parameters and periodic checking to provide accurate radioactivity estimates of beta-gamma emitters in a given clinical

    Tables and figures play a critical role in enhancing the quality of an andrological paper. As visual elements, well-presented tables and figures can reduce the length of the manuscript and meanwhile efficiently capture a large amount of information by clear and concise display of detailed results and complex relationships, patterns and trends, offer explicit statistical or graphical support to important ideas, and add to the value of the whole paper. The effectiveness of a table or figure lies not only in its well-crafted structural design, but even more in its language presentation. This article presents some essential and practical guidelines to effective English writing of the title, body and footnotes of tables and figures in andrological papers.

  14. Figurativeness in the Sense of Distraction (Studies by Lithuanian Authors

    Directory of Open Access Journals (Sweden)

    Laimutė Monginaitė

    2017-04-01

    Full Text Available The phenomenon of the sense of distraction and the feature of figurativeness in it are analysed with the help of phenomenological description, the concept of sense of Juozas Mureika and the conception of imagination of Kristupas Sabolius. The position is followed that the acts of sense and the being of those existing found in them cannot be known in a purely rational way. Knowing is reached with intuitive insights. The experiencing of distraction is approached as one of the norms or intentions of consciousness. The sense of distraction is acknowledged to be a basic value becoming more and more important in a modern stressful life. The article indicates that the intentional beings of the sense of distraction are expressed in really various human activities and are distinguished with mono-subjectivity and unrepeatable feeling. Figurativeness is perceived as the result of imaginary, creative activity of the imagination and aesthetical quality. The peculiarities of the formation of figurativeness are revealed through the phenomenological description of imagination by Sabolius. Four features of the act of visualisation, determining the quality of figurativeness, are emphasized: intentionality, power of transformation, relation with emotions and the symbolism of the image. The conclusion is made that figurativeness, being the result of the creative act (visualisation of imagination, appears as aesthetical quality or the ensemble of qualities. Figurativeness sharpens the sense of distraction and calls the wave of new experiences.

    2017-01-01

    This Sandia National Laboratories / New Mexico (SNL/NM) submittal contains groundwater information that the United States Geological Survey (USGS) has requested. The USGS will use the information to assist Kirtland Air Force Base (KAFB) in its ongoing groundwater studies. The information in this submittal contains well-construction details and groundwater-elevation data for monitoring wells that SNL/NM has installed. Relevant well-construction data from other government agencies are also summarized. This submittal contains four data tables and three figures. Information in the tables has been used by SNL/NM to prepare groundwater compliance reports that have previously incorporated the three figures. The figures depict the potentiometric surface for the Perched Groundwater System, the potentiometric surface for the Regional Aquifer, and a Conceptual Site Model for the vicinity of Tijeras Arroyo in the northern portion of KAFB.

  16. Full text and figure display improves bioscience literature search.

    Directory of Open Access Journals (Sweden)

    Anna Divoli

    Full Text Available When reading bioscience journal articles, many researchers focus attention on the figures and their captions. This observation led to the development of the BioText literature search engine, a freely available Web-based application that allows biologists to search over the contents of Open Access Journals, and see figures from the articles displayed directly in the search results. This article presents a qualitative assessment of this system in the form of a usability study with 20 biologist participants using and commenting on the system. 19 out of 20 participants expressed a desire to use a bioscience literature search engine that displays articles' figures alongside the full text search results. 15 out of 20 participants said they would use a caption search and figure display interface either frequently or sometimes, while 4 said rarely and 1 said undecided. 10 out of 20 participants said they would use a tool for searching the text of tables and their captions either frequently or sometimes, while 7 said they would use it rarely if at all, 2 said they would never use it, and 1 was undecided. This study found evidence, supporting results of an earlier study, that bioscience literature search systems such as PubMed should show figures from articles alongside search results. It also found evidence that full text and captions should be searched along with the article title, metadata, and abstract. Finally, for a subset of users and information needs, allowing for explicit search within captions for figures and tables is a useful function, but it is not entirely clear how to cleanly integrate this within a more general literature search interface. Such a facility supports Open Access publishing efforts, as it requires access to full text of documents and the lifting of restrictions in order to show figures in the search interface.

  17. Figuring large optics at the sub-nanometer level: compensation for coating and gravity distortions.

    Gensemer, Stephen; Gross, Mark

    2015-11-30

    Large, precision optics can now be manufactured with surface figures specified at the sub-nanometer level. However, coatings and gravity deform large optics, and there are limits to what can be corrected by clever compensation. Instead, deformations caused by stress from optical mounts and deposited coatings must be incorporated into the optical design. We demonstrate compensation of coating stress on a 370mm substrate to λ/200 by a process of coating and annealing. We also model the same process and identify the leading effects that must be anticipated in fabrication of optics for future gravitational wave detectors and other applications of large, precisely figured optics, and identify the limitations inherent in using coatings to compensate for these deformations.

  18. Large thermoelectric figure of merit in graphene layered devices at low temperature

    Nanostructured materials have emerged as an alternative to enhance the figure of merit (ZT) of thermoelectric (TE) devices. Graphene exhibits a high electrical conductivity (in-plane) that is necessary for a high ZT; however, this effect is countered by its impressive thermal conductivity. In this work TE layered devices composed of electrochemically exfoliated graphene (EEG) and a phonon blocking material such as poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), polyaniline (PANI) and gold nanoparticles (AuNPs) at the interface were prepared. The figure of merit, ZT, of each device was measured in the cross-plane direction using the Transient Harman Method (THM) and complemented with AFM-based measurements. The results show remarkable high ZT values (0.81  <  ZT  <  2.45) that are directly related with the topography, surface potential, capacitance gradient and resistance of the devices at the nanoscale.

    Full Text Available Hundreds of millions of figures are available in biomedical literature, representing important biomedical experimental evidence. This ever-increasing sheer volume has made it difficult for scientists to effectively and accurately access figures of their interest, the process of which is crucial for validating research facts and for formulating or testing novel research hypotheses. Current figure search applications can't fully meet this challenge as the "bag of figures" assumption doesn't take into account the relationship among figures. In our previous study, hundreds of biomedical researchers have annotated articles in which they serve as corresponding authors. They ranked each figure in their paper based on a figure's importance at their discretion, referred to as "figure ranking". Using this collection of annotated data, we investigated computational approaches to automatically rank figures. We exploited and extended the state-of-the-art listwise learning-to-rank algorithms and developed a new supervised-learning model BioFigRank. The cross-validation results show that BioFigRank yielded the best performance compared with other state-of-the-art computational models, and the greedy feature selection can further boost the ranking performance significantly.

    Figure drawings were obtained from 97 preadolescent males who differed in self and behavioral assessments of self-esteem. These subjects had been selected from a much larger sample and represented five different types of self-esteem. The figure drawings were scored for 15 variables, dealing with formal characteristics, content, and global-interpretations of the total drawings. Five significant differences were obtained, with the content and global-interpretative categories proving more differentiating between self-esteem groups than did the formal characteristics. Behavioral expressions of self-esteem were more associated with figure drawing characteristics than were subjective evaluations. Discussion focuses on the nature of self-concept and self-esteem in children as a sensorimotor rather than symbolic expression.

  2. Cutting solid figures by plane - analytical solution and spreadsheet implementation

    Science.gov (United States)

    Benacka, Jan

    2012-07-01

    In some secondary mathematics curricula, there is a topic called Stereometry that deals with investigating the position and finding the intersection, angle, and distance of lines and planes defined within a prism or pyramid. Coordinate system is not used. The metric tasks are solved using Pythagoras' theorem, trigonometric functions, and sine and cosine rules. The basic problem is to find the section of the figure by a plane that is defined by three points related to the figure. In this article, a formula is derived that gives the positions of the intersection points of such a plane and the figure edges, that is, the vertices of the section polygon. Spreadsheet implementations of the formula for cuboid and right rectangular pyramids are presented. The user can check his/her graphical solution, or proceed if he/she is not able to complete the section.

    A grey pottery figure manufactured in the Western-Han Dynasty and the clay gathered from the same site of Beidongshan near Suzhou, China, have been studied by X-ray diffraction, X-ray fluorescence and Moessbauer spectroscopy. They were simultaneously fired under the same conditions in different atmospheres at various temperatures. The information on original firing atmosphere and temperature as well as its provenance can be inferred from the method of pottery re-firing and clay firing. The original firing temperatures deduced from both of them are in good self-agreement. It is found that the values of Moessbauer parameters for the un-re-fired pottery figure are approximately the same as those for the clay fired at 950 deg C for five hours in a reduced atmosphere. The XRF analysis confirmed that the locality of this pottery figure was somewhere near Beidongshan

    Directory of Open Access Journals (Sweden)

    Christian Giguere

    2015-12-01

    Full Text Available This paper examines the influence of Aristotle’s theory of place (topos on the conceptualization of cultural universality. Its main focus is in reinvesting the thought of Baruch Spinoza and Henri Bergson surrounding the fossilized spatial boundaries that limit understanding in order to scrutinize both the virtual and figurative processes inherent to the sketching of a universal human plane outside of local custom in certain literary works. This investigation yields a concept of “figurative agency” that is then delineated in the Tao Te Ching and Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde in order to demonstrate how the concept might serve as a bridge between the extended space of a national culture and the virtual plane invested by world literature.Keywords: world literature, Henri Bergson, Spinoza, figurative agency, The Strange Case of Dr. Jekyll and Mr. Hyde, Tao Te-Ching, literary epistemology

  6. 3-D vision and figure-ground separation by visual cortex.

    Science.gov (United States)

    Grossberg, S

    1994-01-01

    A neural network theory of three-dimensional (3-D) vision, called FACADE theory, is described. The theory proposes a solution of the classical figure-ground problem for biological vision. It does so by suggesting how boundary representations and surface representations are formed within a boundary contour system (BCS) and a feature contour system (FCS). The BCS and FCS interact reciprocally to form 3-D boundary and surface representations that are mutually consistent. Their interactions generate 3-D percepts wherein occluding and occluded object parts are separated, completed, and grouped. The theory clarifies how preattentive processes of 3-D perception and figure-ground separation interact reciprocally with attentive processes of spatial localization, object recognition, and visual search. A new theory of stereopsis is proposed that predicts how cells sensitive to multiple spatial frequencies, disparities, and orientations are combined by context-sensitive filtering, competition, and cooperation to form coherent BCS boundary segmentations. Several factors contribute to figure-ground pop-out, including: boundary contrast between spatially contiguous boundaries, whether due to scenic differences in luminance, color, spatial frequency, or disparity; partially ordered interactions from larger spatial scales and disparities to smaller scales and disparities; and surface filling-in restricted to regions surrounded by a connected boundary. Phenomena such as 3-D pop-out from a 2-D picture, Da Vinci stereopsis, 3-D neon color spreading, completion of partially occluded objects, and figure-ground reversals are analyzed. The BCS and FCS subsystems model aspects of how the two parvocellular cortical processing streams that join the lateral geniculate nucleus to prestriate cortical area V4 interact to generate a multiplexed representation of Form-And-Color-And-DEpth, or FACADE, within area V4. Area V4 is suggested to support figure-ground separation and to interact with

    The fabrication of large optics is traditionally a slow process, and fabrication capability is often limited by measurement capability. W hile techniques exist to measure mirror figure with nanometer precis ion, measurements of large-mirror prescription are typically limited to submillimeter accuracy. Using a lidar instrument enables one to measure the optical surface rough figure and prescription in virtuall y all phases of fabrication without moving the mirror from its polis hing setup. This technology improves the uncertainty of mirror presc ription measurement to the micron-regime.

    Thin x-ray optics with high angular resolution (≤ 0.5 arcsec) over a wide field of view enable the study of a number of astrophysically important topics and feature prominently in Lynx, a next-generation x-ray observatory concept currently under NASA study. In an effort to address this technology need, piezoelectrically adjustable, thin mirror segments capable of figure correction after mounting and on-orbit are under development. We report on the fabrication and characterization of an adjustable cylindrical slumped glass optic. This optic has realized 100% piezoelectric cell yield and employs lithographically patterned traces and anisotropic conductive film connections to address the piezoelectric cells. In addition, the measured responses of the piezoelectric cells are found to be in good agreement with finite-element analysis models. While the optic as manufactured is outside the range of absolute figure correction, simulated corrections using the measured responses of the piezoelectric cells are found to improve 5 to 10 arcsec mirrors to 1 to 3 arcsec [half-power diameter (HPD), single reflection at 1 keV]. Moreover, a measured relative figure change which would correct the figure of a representative slumped glass piece from 6.7 to 1.2 arcsec HPD is empirically demonstrated. We employ finite-element analysis-modeled influence functions to understand the current frequency limitations of the correction algorithm employed and identify a path toward achieving subarcsecond corrections.

  1. Research as Art: Using figures to make science approachable

    As scientists, we spend a significant amount of time thinking about how best to express the results of our research through figures. These can range from graphs to microscope images to movies, but they all serve the purpose of communicating complicated ideas to our colleagues in the scientific community. One component of scientific data representation that is often overlooked is the aesthetic of the image. Many images produced for data communication and publication are visually engaging even to a lay audience, allowing them to serve as a point of entry to learning about scientific research for the non-specialist. To help researchers embrace this secondary goal of scientific figures, we have instituted an annual event at the Lamont-Doherty Earth Observatory of Columbia University (LDEO) called Research as Art. For this event, scientists submit figures from their work that they see as artistic. These figures are displayed in a gallery-type exhibit for the community to appreciate. This year, the exhibit included movie and sculpture categories, allowing for attendees to interact with a broader range of scientific work. Each piece is accompanied by a brief, non-technical caption. Research as Art provides a gateway for scientists from a broad range of disciplines within the Earth Sciences to learn about work that is entirely unrelated to their own. After the event, attendees commented that they had never before thought about how a non-specialist would view their figures and that they would keep this in mind when making future figures. Thus, one of the biggest benefits of exhibits such as this is to teach scientists to view our work through a non-specialist's eyes. However, future plans for Research as Art include establishing a temporary exhibit at a local bar to expand the reach to a broader segment of the Columbia University area community. Our figures are art, and when we start to treat them that way, we open a world of possibilities for teaching the public about our

  2. Figurative language processing in atypical populations: The ASD perspective

    2015-02-01

    Full Text Available This paper is intended to provide a critical overview of experimental and clinical research documenting problems in figurative language processing in atypical populations with a focus on the Autistic Spectrum. Research in the comprehension and processing of figurative language in autism invariably documents problems in this area. The greater paradox is that even at the higher end of the spectrum or in the cases of linguistically talented individuals with Asperger syndrome, where structural language competence is intact, problems with extended language persist. If we assume that figurative and extended uses of language essentially depend on the perception and processing of more concrete core concepts and phenomena, the commonly observed failure in atypical populations to understand figurative language remains a puzzle.Various accounts have been offered to explain this issue, ranging from linking potential failure directly to overall structural language competence (Brock et al., 2008; Norbury, 2005 to right-hemispheric involvement (Gold and Faust, 2010. We argue that the dissociation between structural language and figurative language competence in autism should be sought in more general cognitive mechanisms and traits in the autistic phenotype (e.g., in terms of weak central coherence, Vulchanova et al., 2012b, as well as failure at on-line semantic integration with increased complexity and diversity of the stimuli (Coulson and van Petten, 2002. This perspective is even more compelling in light of similar problems in a number of conditions, including both acquired (e.g., Aphasia and developmental disorders (Williams Syndrome. This dissociation argues against a simple continuity view of language interpretation.

    The preferential orientation, not alone it exists in metals, but also in minerals or in general in crystalline materials, notwithstanding in the metals it can be transformed by means of those processes of having mechanical worked such as laminate, wrapping, etc. To the preferable orientation of the crystals is also known as texture and since the properties of the crystalline materials lens depend on the orientation that present its glasses, it is important to know its texture. The difficulty for to represent and to describe the grade of preferential orientation in textured materials take to F. Weber to adapt the stereo graphic projection of a monocrystal to a poles figure. Later on, its appeared but methods to obtain the polar figure, among them, that of reflection of L. G. Schultz, but again a technique appears it specifies for its obtaining. In all the cases, the methodology is the following one: a) It is obtained by means of the diffraction process, the correspondent spectra in digitized form. b) it is applied process of having softened mathematician of the spectrum. c) there are determined the fi coordinates, beta and intensity for graph nts of the polar figure. d) Its are graph the points generated in c obtaining the polar figures. The objective of this work, is leaving of a softened spectra, to generate the coordinated fi, beta and corresponding intensity to proceed to their graph and generation of the polar figure. In this specific work, the methodology of Philips is used that consists in making a sweeping in hairspring form with the radiation to detect in these points the execution of the Bragg law. (Author)

    Glovebox wipe surveys were conducted to correlate surface tritium contamination with atmospheric tritium levels. Surface contamination was examined as a function of tritium concentration and limited to the HT/T 2 form. The previously predicted relationship between atmospheric HTO concentration and cleanup times was examined in order to predict a model for atmospheric detritiation of stainless steel enclosures. 2 figures, 2 tables

  5. Surrogate inaccuracy in predicting older adults' desire for life-sustaining interventions in the event of decisional incapacity: is it due in part to erroneous quality-of-life assessments?

    Family members are often called upon to make decisions for an incapacitated relative. Yet they have difficulty predicting a loved one's desire to receive treatments in hypothetical situations. We tested the hypothesis that this difficulty could in part be explained by discrepant quality-of-life assessments. The data come from 235 community-dwelling adults aged 70 years and over who rated their quality of life and desire for specified interventions in four health states (current state, mild to moderate stroke, incurable brain cancer, and severe dementia). All ratings were made on Likert-type scales. Using identical rating scales, a surrogate chosen by the older adult was asked to predict the latter's responses. Linear mixed models were fitted to determine whether differences in quality-of-life ratings between the older adult and surrogate were associated with surrogates' inaccuracy in predicting desire for treatment. The difference in quality-of-life ratings was a significant predictor of prediction inaccuracy for the three hypothetical health states (p quality of life compared to the older adult, the more he or she overestimated the older adult's desire to be treated. Discrepant quality-of-life ratings are associated with surrogates' difficulty in predicting desire for life-sustaining interventions in hypothetical situations. This finding underscores the importance of discussing anticipated quality of life in states of cognitive decline, to better prepare family members for making difficult decisions for their loved ones.

  6. On-orbit figure sensing and figure correction control for 0.5 arc-second adjustable X-ray optics

    Science.gov (United States)

    Reid, Paul

    changed constantly at several cycles/sec (active). In our approach, the mirror figure is corrected based on ground measurements, accounting for figure errors due to mirror manufacturing, mounting induced deformations, modeled gravity release, and modeled on-orbit thermal effects. The piezoelectric strain monitoring we seek to develop in this program extends adjustable mirror technology development, as it enables efficient adjustment and correction of mirror figure on-orbit, as required. This unprecedented level of system robustness will make telescopes less expensive to build because requirements for the non-optical systems can be looser, and it will also make the system more resistant to degradation, promoting mission success. The largest drivers for changes from ground calibration to on-orbit performance are piezoelectric material aging and an unexpected thermal environment (i.e., larger gradients than modeled or other thermal control system problem). Developing the capability to accurately monitor the health of each piezoelectric cell and the local mirror surface temperature will enable the real time sensing of any of these potential issues, help determine the cause, and enable corrections via updating models of on-orbit conditions and re-optimizing the required piezoelectric cell voltages for mirror figure correction. Our 3 year research program includes the development of the strain monitoring technology, its deposition on the adjustable optics, modeling and performance simulation, accelerated lifetime testing, and optical and electrical metrology of sample adjustable optics that incorporate monitoring sensors. Development of the capability to remotely monitor piezo performance and temperature to necessary precision will vastly improve reliability of the SMART-X mission concept, or the sub-arc-second X-ray Surveyor mission described in the 2013 NASA Astrophysics Roadmap, Enduring Quests Daring Visions.

    Full Text Available During the second half of the XIXth century, Europe, the United States and Russia witnessed a blossoming interest in the use of photography in the anthropological field, its specific use was not very clear and defined yet; as a consequence, its heuristic methodologies, technical shooting modalities, stylistic elements and figurative conventions were not clear either. We range goes from anthropometric photography to an ethnographic and folkloric portrait painting signed at the same time by anthropologists and travellers, professional photographers looking for exotic subjects, amateur photographers and soldiers who encourage a figural medley characterised by scientific, commercial and artistic veins that slowly finds its definition in some of its prevailing features, in primis those of the portrait with pictorial origins, however continuously declined and reinterpreted in several ways. In this context Anthropology seeks some links with aesthetics.

    We have investigated the thermoelectrical properties of chiral carbon nanotube and numerically evaluated the figure of merit. We observed that the properties are highly anisotropic and depend on the geometric chiral angle (GCA) θ h , temperature and the overlapping integrals (exchange energy) for the jumps along the tubular axis Δ z and the base helix Δ s . The thermopower α exhibited giant values with the peak occurring between 100 K and 150 K. The electron thermal conductivity showed unusually high value with the peaks shifting towards high temperature. We attribute the high peak values to electron-phonon interactions. Finally we noted that by changing the Δ s and Δ z it is possible to get a figure of merit greater than 1. (author)

  9. The Masculine Image of Presidents As Sporting Figures

    Directory of Open Access Journals (Sweden)

    Aaron J. Moore

    2012-07-01

    Full Text Available This article explores the role of the president identifying himself as a sporting figure, which can be successful as well as detrimental in the presidents’ overall public relations strategy, through an ideological criticism lens. To make this argument, the authors start by examining the role of sports in American popular culture and its relationship to a strong masculine image. Recognizing the value of publicity in the mediated political world, they then trace the evolution of the president from Eisenhower to Obama identifying himself as a sporting figure through the mass media. The article specifically focuses on the two most recent presidents’ use of sports and its effect on their masculine image. The authors conclude by addressing the implications of a future female president’s strategic use of sports.

    Bialystok, Ellen; Shapero, Dana

    2005-11-01

    Two studies are reported in which monolingual and bilingual children, approximately 6 years old, attempted to identify the alternative image in a reversible figure. In both studies, bilingual children were more successful than monolinguals in seeing the other meaning in the images. In the first study, there was no relation between the ability to reverse the interpretation and performance on the children's embedded figures task, a task that superficially appeared to involve similar processes. The second study replicated this finding but showed that performance was strongly related to success in the post-switch phase of the dimensional change card sort task. In both cases, the meaning of an image must be reassigned, and bilinguals were better in both these tasks.

    We present a complete scheme for managing the polarization of ion beams in Jefferson Lab's proposed Medium-energy Electron-Ion Collider (MEIC). It provides preservation of the ion polarization during all stages of beam acceleration and polarization control in the collider's experimental straights. We discuss characteristic features of the spin motion in accelerators with Siberian snakes and in accelerators of figure-8 shape. We propose 3D spin rotators for polarization control in the MEIC ion collider ring. We provide polarization calculations in the collider with the 3D rotator for deuteron and proton beams. The main polarization control features of the figure-8 design are summarized.

  14. Selection and presentation of imaging figures in the medical literature.

    Directory of Open Access Journals (Sweden)

    George C M Siontis

    Full Text Available BACKGROUND: Images are important for conveying information, but there is no empirical evidence on whether imaging figures are properly selected and presented in the published medical literature. We therefore evaluated the selection and presentation of radiological imaging figures in major medical journals. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed articles published in 2005 in 12 major general and specialty medical journals that had radiological imaging figures. For each figure, we recorded information on selection, study population, provision of quantitative measurements, color scales and contrast use. Overall, 417 images from 212 articles were analyzed. Any comment/hint on image selection was made in 44 (11% images (range 0-50% across the 12 journals and another 37 (9% (range 0-60% showed both a normal and abnormal appearance. In 108 images (26% (range 0-43% it was unclear whether the image came from the presented study population. Eighty-three images (20% (range 0-60% had any quantitative or ordered categorical value on a measure of interest. Information on the distribution of the measure of interest in the study population was given in 59 cases. For 43 images (range 0-40%, a quantitative measurement was provided for the depicted case and the distribution of values in the study population was also available; in those 43 cases there was no over-representation of extreme than average cases (p = 0.37. SIGNIFICANCE: The selection and presentation of images in the medical literature is often insufficiently documented; quantitative data are sparse and difficult to place in context.

  15. Combas & Co. or the Figure and the Great Divide

    Directory of Open Access Journals (Sweden)

    Monique Yaari

    1996-06-01

    Full Text Available The young painter, Robert Combas, leader of the 1980s "figuration libre" 'free figuration' movement, is seen here both as representative of stylistic and thematic trends in contemporary French art, and as illustrative, through the unfolding of his career, of the object "painting" and its sociology in contemporary France. Examined are: first, the "Postmodern convergence" of figurative, indeed narrative art, with the collapse of the "great divide" between elite and popular art forms; and second, traits such as hypertrophic verbal paratext, high erotic content, and political stand. Similar threads are followed in the work of a number of other artists, old and young, established or not, female and male—hence the "& Co." of the title. The essay raises, without claiming to solve, a set of sociologically and politically informed questions: What forces have shaped Combas' sensibility and style? What forces have made him a minor celebrity domestically, one that France's awesome cultural apparatus considers worthy of export? What, in the formation of contemporary mentalities and tastes, may account for the parallels found among artists as diverse as Combas, Quardon, Pierre and Gilles, Ben, and Klossowski?

  16. Francis Bacon: The Real's Brutality. The Figure and the Other

    Directory of Open Access Journals (Sweden)

    Guido Mannucci

    2014-03-01

    Full Text Available Getting in front of painting by Francis Bacon touches you deeply. I’m talking about aesthetics, sensations: resounding flow that strikes abruptly, making futile any search for meaning. Francis Bacon circumvents the figurative, the meaning, he aims to the figural: to feelings, not words. Beauty, in his paintings, shows itself in the peaceful union of the positive and of its contrary; if the negative wasn’t there, though, his paintings wouldn’t exude such a brutal sense of reality. This essay investigates the figure of Francis Bacon and the spectator – the Other – as he tries to confront the painting. Bacon will be analysed using a purely phenomenological approach, with references that range from Merleau-Ponty to Martin Heidegger; the meeting-collision between the spectator and the painting, instead, will be examined taking inspiration from the Winnicott’s thesis on the relationship between Bacon and mirrors in the painter’s childhood. In order to take distance from Winnicott’s psychoanalytical approach, this essay will focus on the relationship between spectator and painting from a more anthropological point of view. 

  17. Mitotic Figure Recognition: Agreement among Pathologists and Computerized Detector

    Directory of Open Access Journals (Sweden)

    Christopher Malon

    2012-01-01

    Full Text Available Despite the prognostic importance of mitotic count as one of the components of the Bloom – Richardson grade [3], several studies ([2, 9, 10] have found that pathologists’ agreement on the mitotic grade is fairly modest. Collecting a set of more than 4,200 candidate mitotic figures, we evaluate pathologists' agreement on individual figures, and train a computerized system for mitosis detection, comparing its performance to the classifications of three pathologists. The system’s and the pathologists’ classifications are based on evaluation of digital micrographs of hematoxylin and eosin stained breast tissue. On figures where the majority of pathologists agree on a classification, we compare the performance of the trained system to that of the individual pathologists. We find that the level of agreement of the pathologists ranges from slight to moderate, with strong biases, and that the system performs competitively in rating the ground truth set. This study is a step towards automatic mitosis count to accelerate a pathologist's work and improve reproducibility.

  18. Figuring out’ in science and the humanities

    Directory of Open Access Journals (Sweden)

    Giuseppe Martella

    2011-01-01

    Full Text Available The purpose of this article is to enquire into the notion of change in figures of speech, concepts, topics, and technical instruments-models when they are “travelling” through different milieus, contexts, systems or disciplines. I conceive of this travelling as a basic exchange of energy/information, amounting to an event which can reshape a given field of experience. My argument is based on the premise that our experience happens at multiple levels and areas, and develops along different phases, which imperceptibly flow into each other and bear at times barely decipherable traces of the events that have constituted them. The processes happening at a different level from that of present perception can only be conceived of as infractions of the world tissue and of the related universe of discourse. Therefore in any field of enquiry the process of discovery can develop only through figures of discourse. My thesis is that, at the present stage of techno-science, Scriptural Figurality, which constitutes the basis of both Western epistemology and hermeneutics, is superseded and has to be replaced by a new hypermedial rhetoric, capable to cope with complexity, infraction and emergence, both in science and the humanities.

    2011-01-01

    Full Text Available Borislav Pekic's seven-volume novel 'Golden Fleece' is the most comprehensive Borislav Pekic's prose text in Serbian literature. In this article, we have analyzed the figures of speech in relation to their function in the macrostructural composition of the novel. We have chosen the following figures of speech (style figures: allegory, irony, symbol, and parabasis. In considering these questions, we referred to the knowledge of the language obtained by philosophy of language and linguistics, as a scientific discipline, in adjacent relation to the science of literature. We referred to the views on the nature of language by Martin Heidegger, Ludwig Wittgenstein, Gadamer Hans-Heorg and Ferdinand de Saussure, believing that they (each within its own system of thinking of the world penetrated deeply into the mystery of language. In short-in the in the systems of minds of all listed thinkers, the language is seen or viewed as a tool, or even as the basis of linguistic communication. Borislav Pekic uses allegorical or ironic statements and structures with a view to expose the hypocrisy in relationships between people, to show that beneath every text, a subtext (that erases everything said before emerges. By using a powerful symbol in the narrative and direct intervention in the text (parabasis, the writer dorects the reader to the conclusion that the novel heroes live in dehumanized world, a world without future.

  1. Dissection of Drosophila Visual Circuits Implicative in Figure Motion

    Science.gov (United States)

    Kelley, Ross G.

    The Drosophila visual system offers a model to study the foundations of how motion signals are computed from raw visual input and transformed into behavioral output. My studies focus on how specific cells in the Drosophila nervous system implement this input-output transformation. The individual cell types are known from classical studies using Golgi impregnations, but the assembly of motion processing circuits and the behavioral outputs remain poorly understood. Using an electronic flight simulator for flies and a white-noise analysis developed by Aptekar et al., I screen specific neurons in the optic lobes for behavioral ramifications. This approach produces wing responses to both the spatial and temporal dynamics of motion signals. The results of these experiments give Spatiotemporal Action Fields (STAFs) across the entire visual panorama. Genetically inactivating a distinct grouping of cells in the third optic ganglion, the Lobula Plate, the Horizontal System (HS) cell group, produced a robust phenotype through STAF analysis. Using the Gal4-UAS transgene expression system, we selectively inactivated the HS cells by expressing in their membrane inward rectifying potassium channels (Kir2.1) to hyperpolarize these cells, preventing their role in synaptic signaling. The results of the experiments show mutants lose steering responses to several distinct categories of figure motion and reduced behavioral responses to figure motion set against a contrasting moving background, highlighting their role in figure tracking behavior. Finally, a synapse inactivating protein, tetanus toxin (TNT), expressed in the HS cell group, produces a different behavioral phenotype than overexpressing inward rectifier. TNT, a bacterial neurotoxin, cleaves SNARE proteins resulting in loss of synaptic output of the cell, but the dendrites are intact and signal normally, preserving dendro-dendritic interactions known to sculpt the visual receptive fields of these cells. The two distinct

    2017-10-25

    We describe herein a novel strategy for the fabrication of efficient 3D printed antibacterial scaffolds. For this purpose, both the surface topography as well as the chemical composition of 3D scaffolds fabricated by additive manufacturing were modified. The scaffolds were fabricated by fused deposition modeling (FDM) using high-impact polystyrene (HIPS) filaments. The surface of the objects was then topographically modified providing materials with porous surfaces by means of the Breath Figures approach. The strategy involves the immersion of the scaffold in a polymer solution during a precise period of time. This approach permitted the modification of the pore size varying the immersion time as well as the solution concentration. Moreover, by using polymer blend solutions of polystyrene and polystyrene-b-poly(acrylic acid) (PS 23 -b-PAA 18 ) and a quaternized polystyrene-b-poly(dimethylaminoethyl methacrylate) (PS 42 -b-PDMAEMAQ 17 ), the scaffolds were simultaneously chemically modified. The surfaces were characterized by scanning electron microscopy and infrared spectroscopy. Finally, the biological response toward bacteria was explored. Porous surfaces prepared using quaternized PDMAEMA as well as those prepared using PAA confer antimicrobial activity to the films, i.e., were able to kill on contact Staphylococcus aureus employed as model bacteria.

    One of the requirements for nuclear plant license renewal may be the establishment and demonstration of an effective aging management program. An analysis of both qualitative and quantitative information will be required to define the contents of this aging management program. The authors propose two quantitative figures of merit, Mean Event Detection Frequency and Mean Renewal Rate, that can be used to compare the effectiveness of various inspection, surveillance, test, and monitoring (ISTM) activities for aging mitigation. An example showing the relative effectiveness of an enhanced Loose Parts Monitoring System with current ISTM activities for steam generators and reactor internals is provided. (author)

    Full Text Available Attraverso due racconti di Cortázar, l'analisi di due figure del desiderio ci permette esplorare due estremi seguendo una verticalità. La distruzione, doppio tenebroso della nostra anima, ci rivela un erotismo legato alla morte e al desiderio morboso di possedere l'Altro; il suo contraltare è un'ascesa vertiginosa accompagnata da un godimento estetico, dall'amore sublime prossimo all'esperienza mistica che si concluderà con una discesa progressiva e nel rispetto di questo Altro. La creazione letteraria si presenta come uno sfogo alle nostre angosce, che sono anche una sorta d'espressione dell'erotismo.

    Ambiguous figures reverse their appearance during prolonged viewing and can be perceived in two (or more) available interpretations. Both physical stimulus manipulations and cognitive control influence the perception of ambiguous figures, but the underlying mechanisms remain poorly understood. In the current study, the perception of an ambiguous figure was manipulated by adaptation to unambiguous figures and/or placing the ambiguous figure into a context of unambiguous figures. Our results indicate that both adaptation and context can effectively modulate perception of the ambiguous figure. When manipulated together, adaptation and context processes showed additive effects upon the perception of the ambiguous figure implying the independent mechanisms. Thus, top-down and bottom-up processes seem to influence the perception of the ambiguous figures independently and neither seems to be uniquely responsible for the generation of perceptual changes.

    After an indication of some remarkable key figures (general data, data about office building, housing, industries, renewable energies, wastes, transports, agriculture and forests, and households, indication of some French and European objectives for 2020 and 2030), and a table containing indications of some international official texts (Kyoto protocol and its amendment, European directives) and of their content and scope (bio-fuels in transports, energy efficiency, buildings, labelling and eco-design, transports, renewable energies, energy and climate, greenhouse gas emissions and adaptation, air quality, wastes), and national texts (laws, plans) regarding the same issues, this publication presents figures and data under the form of graphs and tables to illustrate their evolution. They are general data on energy consumptions and intensities (data per sector and per country in Europe), markets and jobs related to renewable energies, certificates of energy saving, greenhouse gas emissions and climate change, regional data for France. The other chapters present large sets of graphs and tables of relevant data concerning housing buildings, office buildings, transports, industries, agriculture and forests, renewable energies and heat networks, wastes, and households. Generally, these data are presented in terms of evolution since the 1970's or the 1990's. They propose a detailed analytical point of view of the various energy and energy-related issues in these different sectors and fields

  10. Metaphorically speaking: cognitive abilities and the production of figurative language.

    2013-02-01

    Figurative language is one of the most common expressions of creative behavior in everyday life. However, the cognitive mechanisms behind figures of speech such as metaphors remain largely unexplained. Recent evidence suggests that fluid and executive abilities are important to the generation of conventional and creative metaphors. The present study investigated whether several factors of the Cattell-Horn-Carroll model of intelligence contribute to generating these different types of metaphors. Specifically, the roles of fluid intelligence (Gf), crystallized intelligence (Gc), and broad retrieval ability (Gr) were explored. Participants completed a series of intelligence tests and were asked to produce conventional and creative metaphors. Structural equation modeling was used to assess the contribution of the different factors of intelligence to metaphor production. For creative metaphor, there were large effects of Gf (β = .45) and Gr (β = .52); for conventional metaphor, there was a moderate effect of Gc (β = .30). Creative and conventional metaphors thus appear to be anchored in different patterns of abilities: Creative metaphors rely more on executive processes, whereas conventional metaphors primarily draw from acquired vocabulary knowledge.

  12. Surreal and Canny Selves: Photographic Figures in Claude Cahun

    Gayle Zachmann

    2003-06-01

    Full Text Available In her 1975 essay, Le Rire de la méduse , Hélène Cixous enthusiastically announced that it was high time for women to enter into discourse. A full half-century earlier, Claude Cahun (1894-1954, a powerful writer and a haunting photographer and artist, was already inscribing herself, Woman, and a woman's voice in visual and verbal self-portraits, photomontages, prose texts, poetry, and aesthetic and political treatises. Cahun's uncanny interventions in both verbal and visual discourse cannily interrogate conventions of literary and pictorial representation and the constructions of self, gender and culture that they exhibit. Insistently asking readers and spectators, "What's wrong with this picture?," her carnivalesque play with the doxa and the politics of identity, destabilizes not only gender and genre norms, but the boundaries and distinctions between visual and verbal representation. Surreal and Canny Selves explores the aesthetic frameworks of writer/artist Claude Cahun. Elucidating how Cahun's questioning of her self and Surrealist representations of woman were part of a much more expansive adventure that questioned more than femininity—the manuscript moves on to trace how and what Cahun's foregrounding of figuration and, more specifically, photographic figuration, might signify for the uncanny aesthetic practices deployed in the hybrid text Aveux non avenus .

    1988-11-01

    The Bender-Gestalt test was administered to 182 Israeli adolescent males: four groups of juvenile delinquents and two of nondelinquent high-school students. Each of the delinquent groups was administered one of the following versions: a standard administration with figure A first (n = 60), a change of sequence with figure A last (n = 22), a regular sequence with figure A changed to two adjacing circles (n = 20), and with figure A changed to two adjacent diamonds (n = 20). One nondelinquent group took the test under standard administration with figure A first (n = 30), and one took it with figure A last (n = 20). The results showed significantly low recall of the original figure A by delinquents when it appeared first. This phenomenon was related to both primary effect and the design depicted in figure A, with a greater influence of the latter. Difficulties in integration were suggested as inhibiting delinquents' recall.

    2016-01-01

    In some applications, like those for particle accelerators and transfer lines, electromagnet loads operate in cycling mode i.e. absorbing or extracting energy from or to a power source. Built-in energy storage such as electrochemical capacitors can be used whose lifetime is heavily depended on the current ripple and depth of discharge. Moreover, the sizing of this storage element is a trade-off between power taken from the grid and energy stored. Additionally, the adopted power conversion structure and control strategy impact on such decision process. In this work, a number of topologies have been evaluated for these applications and the key metrics used to compare them. The proposed figures of merit are used through examples to highlight the trade-offs related with the choice of dc-bus regulation topology and control strategy.

    2017-12-01

    Energy harvesting with triboelectric nanogenerators is a burgeoning field, with a growing portfolio of creative application schemes attracting much interest. Although power generation capabilities and its optimization are one of the most important subjects, a satisfactory elemental model that illustrates the basic principles and sets the optimization guideline remains elusive. We use a simple model to clarify how the energy generation mechanism is electrostatic induction but with a time-varying character that makes the optimal matching for power generation more restrictive. By combining multiple parameters into dimensionless variables, we pinpoint the optimum condition with only two independent parameters, leading to predictions of the maximum limit of power density, which allows us to derive the triboelectric material and device figure of merit. We reveal the importance of optimizing device capacitance, not only load resistance, and minimizing the impact of parasitic capacitance. Optimized capacitances can lead to an overall increase in power density of more than 10 times.

    2012-01-01

    Full Text Available In his pioneering History of Portraiture in Wax, Julius von Schlosser traced back the age-old history of a material which at that time seemed to be already antiquated, if not obsolete. Wax sculptures were rejected and ousted from art history because of their excessive similarity and adherence to models. One hundred years later, however, hyperrealism got its revenge with Maurizio Cattelan’s celebrated hanging children. Moving from that controversial artwork and focusing on the heated polemics over it, my paper will address the question of the well-known Unheimlichkeit of wax figures, investigated by Ernst Jentsch and Sigmund Freud in the early Twentieth Century and nowadays becoming increasingly topical thanks to the recent debate about the existence and nature of the so called Uncanny Valley.

    Full Text Available Waray children are “unconsciously shifting from their mother language to English and/or Tagalog in their vocabulary use”. English vocabularies are more familiar to Waray educands of today than are the indigenous Waray terms, for instance, for geometrical figures, colors, numbers, etc. Still, “it is an ongoing debate of what type of language should be used in the implementation of MTBMLE.” Should educators use a Waray that borrows heavily from English and other languages or a Waray that uses exclusively its own indigenous terms and concepts? The researchers formulate a single lesson plan using an inductive method incorporating the Montessori Approach. We have two types of pupils at LNU-ILS: Waray pupils whose language at home is Waray, and Waray pupils who are exposed to English at home.

    2015-07-01

    Grain boundaries are commonly observed in carbon nanostructures, but their influence on thermal and electric properties is still not completely understood. Using a combined approach of density functional tight-binding theory and nonequilibrium Green functions we investigate electron and phonon transport in carbon-based systems. In this work, quantum transport and thermoelectric properties are summarized for graphene sheets, graphene nanoribbons, and carbon nanotubes with a variety of grain boundary types in a wide temperature range. Motivated by previous findings that disorder scatters phonons more effectively than electrons, a significant improvement in the thermoelectric performance for polycrystalline systems is expected. As the effect is marginally sensitive to the grain boundary type, we demonstrate that grain boundaries are a viable tool to greatly enhance the figure of merit, paving the way for the design of new thermoelectric materials.

    People often search for cues in the environment to determine whether or not they will be judged or treated negatively based on their social identities. Accordingly, feedback from gatekeepers-members of majority groups who hold authority and power in a field-may be an especially important cue for those at risk of experiencing social identity threat, such as women in math settings. Across a series of studies, women who received positive ("Good job!") versus objective (score only) feedback from a male (vs. female) authority figure in math reported greater confidence; belonging; self-efficacy; more favorable Science, Technology, Engineering, and Mathematics (STEM) attitudes/identification/interest; and greater implicit identification with math. Men were affected only by the type of math feedback they received, not by the source of feedback. A meta-analysis across studies confirmed results. Together, these findings suggest that positive feedback from gatekeepers is an important situational cue that can improve the outcomes of negatively stereotyped groups.

    The public is unreasonably concerned and anxious about ionizing radiation. This undefined, irrational, but still real fear of something you know is there even if you cannot perceive it with your five senses is one of the greatest problems the nuclear industry has to attack today. The major problem in this case may be the technical language used by experts. The man in the street has no idea of the technical terms experts use. However, it is possible to make our message clear without the use of any units or figures. A lot can be done for the understanding and confidence by making comparisons to familiar concepts and situations, by taking off our doctors' coats and stepping down to the grass-root level to talk with people in their own everyday language.

    2016-01-01

    Multi-length scale porous polymer (MLSPP) films were fabricated using commercially available polystyrene (PS) via static breath figure (BF) process and sequent hypercrosslinking reaction. One level of ordered pores in microscale were introduced using static BF process, and the other level in nanoscale were produced by the sequent Friedel-Crafts hypercrosslinking reaction. The chemical structure of the PS MLSPP film was investigated by Fourier transformation infrared spectrometry and solid state nuclear magnetic resonance, and the morphology of the film was observed with electron microscopes. The MLSPP films showed large specific surface areas and excellent chemical and thermal stabilities, owing to the micropores and the crosslinked chemical structure produced by the Friedel-Crafts reaction. The methodology reported in this paper is a template-free, low cost and general strategy for the preparation of MLSPP films, which has potential applications in the areas of environment and energy.

    The traditional Mach-Zehnder modulator (MZM) figure of merit (FOM) has been defined as (V π 2 )/υ 3dBe , and works effectively for LiNbO 3 long haul modulators. However, for plasma dispersion based electro-optic modulators, or any modulator that has an inherent relationship between its bandwidth, required drive voltage, and optical insertion loss/gain, this FOM is inappropriate. This is particularly true for short reach links with no optical amplification. In the following, we propose a new modulator FOM (M-FOM) based on device metrics that are essential for short-reach links, such as the peak-to-peak drive voltage, modulator rise-fall time, and relative optical modulation amplitude. Link sensitivity measurements from two MZMs that have different bandwidths and optical losses are compared using our M-FOM to demonstrate its utility. Furthermore, we present a novel application protocol of our M-FOM to provide deeper insight into the relative system impact that modulator performance has on data links with no optical amplification, by taking the ratio of M-FOMs from two modulators driven with the same radio frequency drive power.

    2016-11-01

    Full Text Available Learning idioms which is considered a very essential part of learning and using language (Sridhar and Karunakaran, 2013 has recently attracted a great attention of English learning researchers particularly the assessment of how well Asian language learners acquire and use idioms in communication (Tran, 2013. Understanding and using them fluently could be viewed as a sign towards language proficiency as they could be an effective way to give students better conditions to enhance their communication skills in the daily context (Beloussova, 2015. Investigating how idiomatic expressions are dealt with and processed in a second language or foreign language is an issue worth examining further since it may give language teachers a better idea of some of the strategies language learners use in order to interpret figurative language. Despite their importance, learning and using English idioms by Arab EFL learners have not been investigated extensively, and no research has been conducted on Jordanian students’ idiomatic competency. Thus, the researcher decided to work on these un-tackled issues in the Jordanian context. Most idioms-based investigations are the difficulties Jordanians learners of English face when translating them into Arabic (Hussein, Khanji, and Makhzoumi, 2000; Bataineh and Bataineh, 2002; Alrishan and Smadi, 2015. The analysis of the test showed students’ very poor idiomatic competence; particularly a very limited awareness of the most frequently used idioms despite their overwhelming desire to learn them. Data analysis of the questionnaire revealed the strategies students use and the problems they face in understanding and learning idioms.

    Neuroscience research has thoroughly studied how nonliteral language is processed during metaphor comprehension. However, it is not clear how the brain actually creates nonliteral language. Therefore, the present study for the first time investigates the neural correlates of metaphor production. Participants completed sentences by generating novel metaphors or literal synonyms during functional imaging. Responses were spoken aloud in the scanner, recorded, and subsequently rated for their creative quality. We found that metaphor production was associated with focal activity in predominantly left-hemispheric brain regions, specifically the left angular gyrus, the left middle and superior frontal gyri-corresponding to the left dorsomedial prefrontal (DMPFC) cortex-and the posterior cingulate cortex. Moreover, brain activation in the left anterior DMPFC and the right middle temporal gyrus was found to linearly increase with the creative quality of metaphor responses. These findings are related to neuroscientific evidence on metaphor comprehension, creative idea generation and episodic future thought, suggesting that creating metaphors involves the flexible adaptation of semantic memory to imagine and construct novel figures of speech. Furthermore, the left DMPFC may exert executive control to maintain strategic search and selection, thus facilitating creativity of thought. Copyright © 2013 The Authors. Published by Elsevier Inc.

  20. Documents and detachment in the figurational sociology of sport

    Directory of Open Access Journals (Sweden)

    Paddy Dolan

    2015-01-01

    Full Text Available This article discusses the methodological implications of using a figurational approach to the study of Gaelic games (the Irish sports of hurling and Gaelic football and their organisation and governance from the late nineteenth century onwards. Following Norbert Elias, we argue that data generation guided by theories, and potentially modifying such theories, are essential components of research endeavours. The problem of generalisation or representativeness of historical documents can be addressed by treating documents as part of a fi guration of evidence, thereby constituting a mutually supporting network of data that serves as a scaffold or structure for theoretical and empirical findings. Based on the experience of using documents such as newspaper and referee reports of matches, and also organisational documents such as the minutes of meetings at various levels of governance, we contribute to the discussion concerning borders and boundary maintenance between history, sociology and historical sociology. While we elaborate on the Eliasian perspective on emotional detachment, and secondary involvement, when conducting research, we also note the dificulties in avoiding ‘preferred’ readings of national history given that Gaelic games have been intertwined with the narrative and project of national self-determination in Ireland. Researchers are compelled to recognise the theoretical significance of sports as a motor and symbol of emotional identifications, but must also create distance from their own national habitus in order to prioritise participation in intergenerational knowledge generation over further national myth-making.

    Full Text Available The article concerns itself with the figure of the teacher in Estonian society. We do not concentrate on the educational system as a whole, but on one specific and crucial element in this apparatus - the teacher. We begin by offering a brief historical overview of the conditions of pedagogues in the 20th century before moving on to describe the adoption of neo-liberal free market policies since the 1990s and the effects these policies had and still have on education. Our main concern is to understand the teacher as an actor in power relations; to achieve this understanding we have selected as our examples 1 surveillance techniques in school environment that have direct relations to the state and the market; and 2 the 2012 educational workers' strike that made it quite clear that the teachers have been fixed to a position of wage workers. The overall and more abstract aim of the paper is to think about the social role of the teacher in Estonia.

    The efficient use of reversible thermal effects in magnetocaloric, electrocaloric, and elastocaloric materials is a promising avenue that can lead to a substantially increased efficiency of refrigeration and heat pumping devices, most importantly, those used in household and commercial cooling applications near ambient temperature. A proliferation in caloric material research has resulted in a wide array of materials where only the isothermal change in entropy in response to a handful of different field strengths over a limited range of temperatures has been evaluated and reported. Given the abundance of such data, there is a clear need for a simple and reliable figure of merit enabling fast screening and down-selection to justify further detailed characterization of those material systems that hold the greatest promise. Based on the analysis of several well-known materials that exhibit vastly different magnetocaloric effects, the Temperature averaged Entropy Change is introduced as a suitable early indicator of the material's utility for magnetocaloric cooling applications, and its adoption by the caloric community is recommended.

  3. Figures of Merit Guiding Research on Organic Solar Cells

    While substantial progress in the efficiency of polymer-based solar cells was possible by optimizing the energy levels of the polymer and more recently also the acceptor molecule, further progress beyond 10% efficiency requires a number of criteria to be fulfilled simultaneously, namely, low energy-level offsets at the donor–acceptor heterojunction, low open-circuit voltage losses due to nonradiative recombination, and efficient charge transport and collection. In this feature article we discuss these criteria considering thermodynamic limits, their correlation to photocurrent and photovoltage, and effects on the fill factor. Each criterion is quantified by a figure of merit (FOM) that directly relates to device performance. To ensure a wide applicability, we focus on FOMs that are easily accessible from common experiments. We demonstrate the relevance of these FOMs by looking at the historic and recent achievements of organic solar cells. We hope that the presented FOMs are or will become a valuable tool to evaluate, monitor, and guide further development of new organic absorber materials for solar cells.

  4. Theatre as a Figure and a Place of Cultural Memory

    Full Text Available Cultural memory is the starting point for studying culture. Theatre, on the other hand, is a multidimensional play with memory; it is an emblem of a certain culture, and of the overall blending of various discourses within it. Hence the relation between theatre and memory is rather complex and multifaceted. Theatre is a medium synthesising text and performance, speech and gesture (play, acting, as well as establishing direct, at least doubly articulated communication: among the actors on stage on the one hand, and between the actors and the audience on the other. They are all subjects of theatrical memory. Theatre not only uses memory in order to create the plot, develop the characters or establish communication with the audience, but also becomes a figure of memory itself: a culturally modelled, socially mandated (iconic, narrative, etc. memory image (Assman. Additionally, theatre may be considered a place of memory, as well. But theatre is not a simple mnemonic of repeating reality—it is not merely a simulacrum, but also a quotation of reality; it does not aim to copy or memorise reality, but to represent it and interpret it critically. This is particularly true of the contemporary rough theatre of brutality.

    Full Text Available Abstract Elite adolescent figure skaters must accommodate both the physical demands of competitive training and the accelerated rate of bone growth that is associated with adolescence, in this sport that emphasizes leanness. Although, these athletes apparently have sufficient osteogenic stimuli to mitigate the effects of possible low energy availability on bone health, the extent or magnitude of bone accrual also varies with training effects, which differ among skater disciplines. Purpose We studied differences in total and regional bone mineral density in 36 nationally ranked skaters among 3 skater disciplines: single, pairs, and dancers. Methods Bone mineral density (BMD of the total body and its regions was measured by dual energy x-ray absorptiometry (DXA. Values for total body, spine, pelvis and leg were entered into a statistical mixed regression model to identify the effect of skater discipline on bone mineralization while controlling for energy, vitamin D, and calcium intake. Results The skaters had a mean body mass index of 19.8 ± 2.1 and % fat mass of 19.2 ± 5.8. After controlling for dietary intakes of energy, calcium, and vitamin D, there was a significant relationship between skater discipline and BMD (p = 0.002, with single skaters having greater BMD in the total body, legs, and pelvis than ice dancers (p  Conclusions Single and pair skaters have greater BMD than ice dancers. The osteogenic effect of physical training is most apparent in single skaters, particularly in the bone loading sites of the leg and pelvis.

    The aim of research is to study of the spirometry figures of bronchoobstructive syndrome in concomitant intestinal parasitosis. There are 81 patients aged from 5 to 61 years (male 43, female 38) were examined. The patients were divided into 2 groups: 1 group - patients treated only with bronchodilator therapy (14 patients with protozoa, 14 - with helminth, 12 - with combination of parasitosis); 2 group - patients treated with bronchodilator therapy in common with anti-parasitic therapy (14 patients with protozoa, 17 - with helminth, 10 - with combination of parasitosis). There are 22 patients with bronchoobstructive syndrome without parasites were included in control group. Functional disorders at the initial examination are not significantly distinguished between patients with protozoa, helminth, with combined parasitosis and patients without parasites. Considerable differences manifested in dynamics after treatment: only bronchodilator therapy of patients infected with parasites is not lead to sufficient increase of the indices of external respiration function, even the decreasing of the most parameters were observed in patients with helminth. The least growth of spirometric indices were observed in patients from group 1 - 2,17/ 5,09% predicted volumes (-6,81min; 10,54max), the highest growth were observed in patients from group 2 - 20,26/ 12,45% p.v. (2,77min; 43,85max). The spirographic indicators increase after treatment in the control group was more moderate in comparison with 1 and 2 groups - 5,96/ 2,97% p.v. (0,39min; 9,59max). Thus, using antiparasitic therapy in common with bronchodilator therapy in treatment of patients with intestinal parasitosis (group 2) is lead to the reliably significant positive dynamic of spirometry parameters in comparison not only to 1 group (<0,05 for many parameters) but also to control group (<0,01 for many parameters).

  11. Thirteen years of the fight against doping in figures.

    Every year, the World Anti-Doping Agency (WADA) publishes the main statistics reported by the accredited laboratories, which provide very valuable information for assessing changes in the patterns of doping in sports over time. Using the information provided since 2003 as the basis for the analysis, the evolution of doping/anti-doping figures over the last decade can be examined in reasonable detail, at least in reference to samples analyzed and categories of substances more commonly found in athletes' samples. This brief analysis of the WADA statistical reports leads us to the following outcomes: the increase in anti-doping pressure from 2003 to 2015, as evidenced by increased numbers of samples analyzed and banned substances, has not directly produced a higher frequency of adverse/atypical findings. Although this could be interpreted as steady state in the capacity to detect doping through this whole period, it also resulted in a significant increase in the absolute number of samples catalogued as doping (from 2247 in 2003 to 5912 in 2015). Anabolic agents have been the most common doping substances detected in all statistics reports while the remaining groups of substances are much less frequently found in doping control samples. Given that one might have expected the enhancement of the anti-doping programme led by WADA over this last decade to have increased the percentage of adverse/atypical findings, the fact that it did not might indicate the need to take another step in sampling strategies, such as 'more intelligent testing' based on the differences in the prevalence of doping substances among sports.

  13. Arrays of Hollow Silica Half-Nanospheres Via the Breath Figure Approach

    KAUST Repository

    Gao, Yangqin

    2015-04-21

    Breath figures (BFs) are patterns of liquid droplets that usually form upon condensation on a cold surface. Earlier work has shown that BFs can be used to produce continuous films of porous honeycomb-structured patterns on various types of materials, paving the path to a number of important applications such as the manufacturing of highly ordered nano- and micron-sized templates, micro lenses, and superhydrophobic coatings. It is worth noting, however, that few new findings have been reported in this area in recent years, limiting pursuits of novel architectures and key applications. In this report, an alternative method is described by which arrays of hollow silica half-nanospheres can be produced via BF templates. In the present method, a chemical vapor deposition (CVD) protocol performed while the BF is formed on a glass substrate yields a nanostructured pattern of silica half-spheres, which size (100-700 nm) and density across the glass surface vary with substrate modification and with the relative rates of water condensation and hydrolysis from silica precursors (a process carried out at room temperature). This method of forming arrays of hollow half-nanospheres via the BF approach may be applicable to various other oxides and a broad range of substrates including large-area flexible plastics. © 2015 WILEY-VCH Verlag GmbH & Co.

    Herein, we report the fabrication of microstructured porous surfaces with controlled enzymatic activity by combining the breath figures and the layer-by-layer techniques. Two different types of porous surfaces were designed based on fluorinated and carboxylated copolymers in combination with PS, using poly(2,3,4,5,6-pentafluorostyrene)-b-polystyrene (PS5F31-b-PS21) and polystyrene-b-poly(acrylic acid) (PS19-b-PAA10) block copolymers, respectively. For comparative purposes, flat surfaces having similar chemistry were obtained by spin-coating. Poly(sodium 4-styrenesulfonate)/poly(allylamine hydrochloride) (PSS/PAH) multilayers incorporating alkaline phosphatase (ALP) were built on these porous surfaces to localize the enzyme both inside and outside of the pores using PS/PS5F31-b-PS21 surfaces and only inside the pores on PS/PS19-b-PAA10 surfaces. A higher catalytic activity of ALP (about three times) was obtained with porous surfaces compared to the flat ones. The catalysis happens specifically inside the holes of PS/PS19-b-PAA10surfaces, where ALP is located. This opens the route for applications in microreactors.

    Full Text Available Article is devoted to features of realization of figurativeness in the Turkish political discourse of an oral public statement. As material for the analysis oral public statements of modern Turkish politicians have served. A research objective - to define language means at the expense of which figurativeness in the Turkish political discourse of an oral public statement is realized. In article the conclusion is drawn that the tripartite structure of an image unites signs of an initial subject, transfers them to a new subject, and the new word (phrase gains new value. Figurativeness is structural-semantic property of the word, in each word figurativeness is concluded. The thought that understanding by the recipient of figurative maintenance of a lexical unit and the communicative importance of the image realized in her show contexts is emphasized. Each figurative word and expression possesses the associative resources. Ability of the recipient to understand the right sense put in figurative lexicon depends on completeness of association. The concept of figurativeness is accompanied by concept of a metaforization. Figurative means of language in an oral public statement of the politician are a certain instrument of impact on audience with the purpose to influence vision of a political situation. In the Turkish political discourse of an oral public statement there are both universal, and cultural features of functioning of figurative language means. Figurativeness implementers in this research are understood as graphic means of language, namely a track, such as a metaphor, a metonymy, figurative comparison, the phraseological unit, an epifor and others.

    Full Text Available As mulheres que tanto a história como a imaginação popular mitificaram como "bruxas" constituem figuras que expurgam as fobias da Contra Reforma. As bruxas foram torturadas e queimadas para sinalizar os perigos de práticas e saberes à margem da Igreja e de outras instituições dominantes na Idade Moderna. Parteiras, curandeiras e carpideiras, as bruxas misturam em seu caldeirão os mistérios da vida e da morte herdados das tradições pagãs. Este artigo percorre textos de historiadores, em especial o de Jules Michelet, que no século XIX construiu a imagem romântica e martirizada da bruxa, e o manual de inquisidores do século XIV, o Malleus Maleficarum, que descreve os poderes da bruxa, sua aliança com o demônio e sua ameaça para o cristianismo. Os discursos instaurados por tais textos constroem tanto a imagem que glorifica a bruxa quanto aquela que a execra, mostrando ambas o potencial transformador de suas práticas e de sua ligação com a sexualidade.The women whom history and popular imagination mythicized as "witches" constitute figures that purge the phobias of the Counter Reformation. Witches were tortured and burned to signal the dangers of practices and knowledge in the margins of the Church and other dominant institutions in the Modern Age. Midwives, healers and weepers, the witches blend in their large kettle the mysteries of life and death inherited from pagan traditions. This paper examines some historians' texts, especially that of Jules Michelet, who created the witch's romantic and martyred image, and the inquisitors' manual Malleus Maleficarum, that describes the witch's powers, her alliance with the demon and her threat to Christianity. These texts establish, through their different discourses, two opposing images: one that glorifies witches and another that execrates them, in order to show the transforming potential of their practices and their connection with sexuality.

    Any polycrystalline aggregate normally has a preferred crystallographic orientation, or texture which depends on its thermal and or mechanical history. Preferred orientation is best described by means of a pole figure. A pole figure is a stereographic projection which shows the variation in pole density with pole orientation, for a selected set of crystal planes. In this work, computer programs was developed to plot pole figures. The corrected intensities are calculated and directly transmitted to the plotter. The different intensities levels are represented by different colors in the pole figure. (author)

    The figures included in many of the biomedical publications play an important role in understanding the biological experiments and facts described within. Recent studies have shown that it is possible to integrate the information that is extracted from figures in classical document classification and retrieval tasks in order to improve their accuracy. One important observation about the figures included in biomedical publications is that they are often composed of multiple subfigures or panels, each describing different methodologies or results. The use of these multimodal figures is a common practice in bioscience, as experimental results are graphically validated via multiple methodologies or procedures. Thus, for a better use of multimodal figures in document classification or retrieval tasks, as well as for providing the evidence source for derived assertions, it is important to automatically segment multimodal figures into subfigures and panels. This is a challenging task, however, as different panels can contain similar objects (i.e., barcharts and linecharts) with multiple layouts. Also, certain types of biomedical figures are text-heavy (e.g., DNA sequences and protein sequences images) and they differ from traditional images. As a result, classical image segmentation techniques based on low-level image features, such as edges or color, are not directly applicable to robustly partition multimodal figures into single modal panels. In this paper, we describe a robust solution for automatically identifying and segmenting unimodal panels from a multimodal figure. Our framework starts by robustly harvesting figure-caption pairs from biomedical articles. We base our approach on the observation that the document layout can be used to identify encoded figures and figure boundaries within PDF files. Taking into consideration the document layout allows us to correctly extract figures from the PDF document and associate their corresponding caption. We combine pixel

We present new examples of 3-d PDF figures, explain how they have been made, validate them, and comment on their advantages over traditional, static 2-dimensional (2-d) figures. With the judicious use of 3-d rather than 2-d figures, scientists can now publish, share and archive more useful, flexible and faithful representations of their study outcomes. The article you are reading does not have embedded 3-d figures. The full paper, with embedded 3-d figures, is recommended and is available as a supplementary download from PLoS ONE (File S2).

    Full Text Available The title of this study is, “An Analysis of Figurative Languages Used in Paulo Coelho’s novel Entitled “The Alchemist”. The objectives of the study are to describe the types of the figurative language found in the book and to identify the contextual meaning of the figurative language. The method used in collecting the data related to the subject of this research is documentation method because the researcher collected the data from novel. This study was conducted by collecting any relevant data and information about the topic or problem of the study from novels and internet that are available for the analysis. The data collection used the following steps: reading the novel, and then selecting the data that used the types of figurative language. While the steps to analyze the data are identifying the types of figurative language according to Leech, identifying the contextual meaning of the figurative language, and the last is interpreting the data.The result shows that there are 70 sentences that have figurative language. From all the sentences, there are 30 items or 42.9% of simile, 27 items or 38.6% of personification, 12 items or 17.1% of metaphor, and 1 item or 1.4% of hyperbole. It can be indicated that the dominant type of figurative language in the novel is simile. The author uses simile to explain circumstances, to describe the characters, to express emotion of the characters, and to make his writing more vivid and entertaining. It can be concluded that figurative language has important roles in this novel. That‘s why the author used so many sentences that have figurative language in this novel. Using figurative language makes the novel more interesting to read, and helps the readers to imagine the story, the character based on the illustration that the author has already given in the story.

    Human activities are changing the composition of the atmosphere. In particular the burning of fossil fuels emits carbon dioxide, one of the so-called ''greenhouse gases'' that help maintain the Earth's surface at a temperature suitable for life. They transmit incoming sunlight but trap outgoing radiated heat. Levels of greenhouse gases are increasing, giving rise to concern that the world may warm further, leading to climate change. Energy efficiency can make an important contribution to controlling the greenhouse effect, and brings further benefits for industry and commerce through cost savings. 17 figs

    Full Text Available Sophie Calle's texts are elaborate devices that facilitate the production of figures, of complex symbolic entities. In fact, her work enables us to better understand how figures emerge and unfold in the imaginary. Thus, we find in her Disparitions (Disappearances, a startling figure, which we can name the "Vanished Child". I will present this figure and explain how it stems from the description of a painting by Rembrandt, stolen at the Gardner Museum in Boston. I will start by identifying some of the essential processes implied in the identification of a figure, and, to do so, I will give two short examples, drawn from Witold Gombrowicz and Don DeLillo. Then, after having described in details the figure of the Vanished Child, I will argue, following the French art historian Georges Didi-Huberman in his reading of Walter Benjamin, that figures are auratic objects. Dans ses textes, Sophie Calle emploie des techniques détaillées qui facilitent la production de figures, d'entités symboliques complexes. Son œuvre nous permet effectivement de mieux comprendre comment les figures émergent et se déploient dans l'imaginaire. Ainsi, nous trouvons dans ses Disparitions (Disappearances une figure surprenante que nous pouvons désigner comme « l'enfant disparu ». Je présenterai cette figure en expliquant comment elle découle de la description d'un tableau de Rembrandt volé au musée Gardner à Boston. J'identifierai d'abord quelques-uns des procédés essentiels à l'identification d'une figure, et pour ce faire je donnerai deux exemples, tirés des œuvres de Witold Gombrowicz et Don DeLillo. Puis je décrirai de façon détaillée la figure de l'enfant disparu, avant de démontrer le caractère auratique des figures à partir de la lecture de Walter Benjamin qu'exécute l'historien de l'art français Georges Didi-Huberman.

    Mammography represents the most powerful screening tool available for the early detection of breast cancer. As a screening technique, it addresses to asymptomatic women and therefore the implementation of the 'As Low As Reasonably Achievable' (ALARA) principle is of increased importance. The overall optimization of any radiographic procedure requires the definition of a suitable Figure of Merit (FOM), based on a representative combination of image quality and dose characteristics. For the present study, Monte Carlo simulation of the mammographic process was utilized to derive the energy deposition inside the breast phantom and the signal beneath it. Certain signal characteristics (Subject Contrast (SC), Contrast to Noise Ratio (CNR), squared CNR) were studied (normalized to the output signal) and combined with appropriate dose indices (Entrance Surface Dose (ESD), Average Glandular Dose (AGD), Mid Plane Dose (MPD)) to extract an appropriate FOM index, suitable for spectrum based optimization. Results, for different breast glandularities and lesion sizes and compositions, demonstrate that the choice of the optimum spectrum strongly depends not only on the breast and lesion characteristics, but also on the selection of the utilized FOM index. For screen-film mammography, where the primary image quality index is considered the SC, the traditionally used Mo and Rh-anode spectra demonstrate improved overall performance, despite their inferior dosimetric characteristics compared to W-anode spectra. If digital mammography is considered, where the CNR is of primary importance, W-anode spectra demonstrate a noticeable improved performance.

    We investigate the figure of merit of a quantum dot (QD) system irradiated with an external microwave filed by nonequilibrium Green's function (NGF) technique. Results show that the frequency of microwave field influence the figure of merit ZT significantly. At low temperature, a sharp peak can be observed in the figure of merit ZT as the frequency of ac field increases. As the frequency varies, several zero points and resonant peaks emerge in the figure of merit ZT. By adjusting the frequency of the microwave field, we can obtain high ZT. The figure of merit ZT increases with the decreasing of linewidth function Γ. In addition, Wiedemann–Franz law does not hold, particularly in the low frequency region due to multi-photon emission and absorption. Some novel thermoelectric properties are also found in two-level QD system.

  12. Can music be figurative? Exploring the possibility of crossmodal similarities between music and visual arts

    Directory of Open Access Journals (Sweden)

    Actis-Grosso Rossana

    2017-01-01

    Full Text Available According to both experimental research and common sense, classical music is a better fit for figurative art than jazz. We hypothesize that similar fits may reflect underlying crossmodal structural similarities between music and painting genres. We present two preliminary studies aimed at addressing our hypothesis. Experiment 1 tested the goodness of the fit between two music genres (classical and jazz and two painting genres (figurative and abstract. Participants were presented with twenty sets of six paintings (three figurative, three abstract viewed in combination with three sound conditions: 1 silence, 2 classical music, or 3 jazz. While figurative paintings scored higher aesthetic appreciation than abstract ones, a gender effect was also found: the aesthetic appreciation of paintings in male participants was modulated by music genre, whilst music genre did not affect the aesthetic appreciation in female participants. Our results support only in part the notion that classical music enhances the aesthetic appreciation of figurative art. Experiment 2 aimed at testing whether the conceptual categories ‘figurative’ and ‘abstract’ can be extended also to music. In session 1, participants were first asked to classify 30 paintings (10 abstract, 10 figurative, 10 ambiguous that could fit either category as abstract or figurative and then to rate them for pleasantness; in session 2 participants were asked to classify 40 excerpts of music (20 classical, 20 jazz as abstract or figurative and to rate them for pleasantness. Paintings which were clearly abstract or figurative were all classified accordingly, while the majority of ambiguous paintings were classified as abstract. Results also show a gender effect for painting’s pleasantness: female participants rated higher ambiguous and abstract paintings. More interestingly, results show an effect of music genre on classification, showing that it is possible to classify music as figurative or

  13. Italian cancer figures, report 2012: Cancer in children and adolescents.

    Science.gov (United States)

    2013-01-01

    . The expected number of cancer cases in children aged between 0 and 14 years of age is approximately 7,000 in the period 2016- 2020, while the corresponding figure for adolescents between 15 and 19 years of age is 4,000, with no relevant variation in comparison with the previous five-year period. The present findings update descriptive cancer epidemiology in children and adolescents in Italy based on data provided by an extensive network of general and specialized population-based cancer registries. Data obtained from cancer registries are supplemented by additional information collected by specialized clinical AIEOP centres and mortality reports collected by the National Institute of Statistics (ISTAT). Incidence rates reported in Italy were slightly higher in comparison to other developed Countries, but relatively consistent between different Italian areas. Our results also showed that the significant increase in cancer incidence observed until the end of Nineties has halted, with the exception solely of thyroid cancer in adolescents. Efficacy of therapeutic protocols has improved constantly since the Seventies, and recent findings confirm this trend in all age groups and, in particular, for rarer tumours and cancer types that have very poor prognosis. Findings derived from cross-analysis with AIEOP data suggest that it is possible to further improve the efficiency of our healthcare system, in particular for adolescents; migration can be reduced with a more rational use of hospitals throughout Italy.

  14. Problems in Translating Figures of Speech: A Review of Persian Translations of Harry Potter Series

    Full Text Available Due to the important role of figures of speech in prose, the present research tried to investigate the figures of speech in the novel, Harry Potter Series, and their Persian translations. The main goal of this research was to investigate the translators’ problems in translating figures of speech from English into Persian. To achieve this goal, the collected data were analyzed and compared with their Persian equivalents. Then, the theories of Newmark (1988 & 2001, Larson (1998, and Nolan (2005 were used in order to find the applied strategies for rendering the figures of speech by the translators. After identifying the applied translation strategies, the descriptive and inferential analyses were applied to answer the research question and test its related hypothesis. The results confirmed that the most common pitfalls in translating figures of speech from English into Persian based on Nolan (2005 were, not identifying of figures of speech, their related meanings and translating them literally. Overall, the research findings rejected the null hypothesis. The findings of present research can be useful for translators, especially beginners. They can be aware of the existing problems in translating figures of speech, so they can avoid committing the same mistakes in their works.

    Systematic reviewers often encounter incomplete or missing data, and the information desired may be difficult to obtain from a study author. Thus, systematic reviewers may have to resort to estimating data from figures with little or no raw data in a study's corresponding text or tables. We discuss a case study in which participants used a publically available Web-based program, called webplotdigitizer, to estimate data from 2 figures. We evaluated and used the intraclass coefficient and the accuracy of the estimates to the true data to inform considerations when using estimated data from figures in systematic reviews. The estimates for both figures were consistent, although the distribution of estimates in the figure of a continuous outcome was slightly higher. For the continuous outcome, the percent difference ranged from 0.23% to 30.35% while the percent difference of the event rate ranged from 0.22% to 8.92%. For both figures, the intraclass coefficient was excellent (>0.95). Systematic reviewers should consider and be transparent when estimating data from figures when the information cannot be obtained from study authors and perform sensitivity analyses of pooled results to reduce bias.

    The article contributes to a revision of today’s understanding of the 1950s Danish art scene. By presenting three exhibitions and analysing the reception of them, I point out that figurative art enjoyed a much more central role than later accounts have recognised. All three exhibitions were...... entitled Mennesket (Man), and featured figurative, graphic art, concerned with depictions of the human figure and with the post-war psychological condition of the individual human being. Among the artists were Palle Nielsen, Svend Wiig Hansen, Dan Sterup-Hansen and Henry Heerup. The exhibitions took place...

  18. Un lieu pour les figures dans la théorie de l’argumentation A Place for Rhetorical Figures in Argumentation Theory

    Directory of Open Access Journals (Sweden)

    Christian Plantin

    2009-04-01

    Full Text Available A partir du traitement des figures dans le Traité de l’Argumentation (TA de Perelman et Olbrechts-Tyteca, cet article porte sur la question de la place des figures dans la théorie de l’argumentation. La première partie revient brièvement sur différentes formes de rhétorique, dont une rhétorique de l’ornement ayant pour instrument principal les figures. Une théorie moderne de l’argumentation orientée vers la recherche des fallacies établit une coupure radicale entre argumentation, instrument de recherche de la vérité et rhétorique ornée, que Locke caractérise comme « a powerful instrument of error and deceit ». Cette conception suppose l’usage d’un langage qu’on peut rapidement caractériser comme « artificiel », qui n’est pas celui de l’argumentation ordinaire. Avant d’être des « decorations » les figures sont des « instruments » de structuration de la parole ; et les topoi, instruments de l’argumentation, n’obéissent pas à d’autres mécanismes que les tropes, qui semblent toujours parler à côté et manquer leur objet. La seconde partie s’intéresse à une partie quelque peu délaissée du TA, l’usage qu’il fait des figures et la vision théorique, à la fois cavalière et décisive, qu’il en propose. Le TA ouvre la voie à une conception des figures non pas comme « vain ornement » mais comme une première sémantique du discours argumentatif ; c’est ce qu’on peut montrer sur le cas des « figures du choix, de la présence et de la communion ». En conséquence, la pensée des figures peut et doit être intégrée à une théorie de l’argumentation qui prend en compte le langage dans la parole, avec ses stratégies de construction des objets, du locuteur, de l’interlocuteur et de leurs émotions.This paper deals with the treatment of figures of speech in Perelman’s and Olbrechts-Tyteca’s Treatise on Argumentation (TA, and, more broadly, with the place of

    Full Text Available This article is a content analysis of the socio– demographic characteristics and the social and commercialfunctions carried out by the human figure in the beverage commercials broadcasted in Spain in 2006. The used methodology combines the qualitative with the quantitative analysis. Given the fact that human figures can be present in different forms inthe commercials: being a character of a story, a presenter or a voice over, we have studied those forms separately and jointly:we have identified their socio– demographics characteristics (social class, sex, age putting them in relation with the target.We have also studied the relation of the human figure with other human figures also presents in the commercials,distinguishing between their familiar roles, their labour roles and their commercial roles: what relation do they have with theproduct.

  2. Children's figure ratings: relationship to self-esteem and negative stereotyping.

    Science.gov (United States)

    Tiggemann, M; Wilson-Barrett, E

    1998-01-01

    Numerous studies have used figure ratings to demonstrate substantially greater body dissatisfaction among women than men. The present study aimed to investigate gender differences in body dissatisfaction in younger children. A children's version of the Figure Rating Scale was administered to 140 children between the ages of 7 and 12 years. Children also completed measures of self-esteem and negative stereotyping of fat people. Irrespective of age, girls rated their ideal figure as smaller than the one they considered most attractive to boys, and as substantially smaller than their current figure. For boys, there was no difference in ratings. Level of body dissatisfaction correlated negatively with self-esteem and positively with negative stereotyping for boys, but not for girls. The results are consistent with body dissatisfaction being "a normative discontent" for young girls as well as for adult women.

    2016-01-01

    This article develops an analytic approach to comedic performance by examining the performance of the Chapayeka ritual clowns as a series of semiotic shifts and reversals: the Chapayekas play with images and contexts, introducing unpredictable figures to effectively shift the grounding conditions...... to function as both symbolic figures in the ritual and self-contained contextual grounds, which enables them to produce further signs and manipulate figure-ground relations within and beyond the ritual. The analytic view developed here is informed by the complex and multilayered semiotics of comedic...... performance; this exploration offers a novel perspective on how comedic performances create and wield semiotic force through establishing grounds and evoking figure-ground relations....

  7. Central Coherence in Eating Disorders: A Synthesis of Studies Using the Rey Osterrieth Complex Figure Test.

    Directory of Open Access Journals (Sweden)

    Katie Lang

    Full Text Available Large variability in tests and differences in scoring systems used to study central coherence in eating disorders may lead to different interpretations, inconsistent findings and between study discrepancies. This study aimed to address inconsistencies by collating data from several studies from the same research group that used the Rey Osterrieth Complex Figure Test (Rey Figure in order to produce norms to provide benchmark data for future studies.Data was collated from 984 participants in total. Anorexia Nervosa, Bulimia Nervosa, recovered Anorexia Nervosa, unaffected family members and healthy controls were compared using the Rey Figure.Poor global processing was observed across all current eating disorder sub-groups and in unaffected relatives. There was no difference in performance between recovered AN and HC groups.This is the largest dataset reported in the literature and supports previous studies implicating poor global processing across eating disorders using the Rey Figure. It provides robust normative data useful for future studies.

  8. Conoscopic figure: a complex consequence of a not so simple phenomenon

    Science.gov (United States)

    Pečar, Maja; Čepič, Mojca

    2015-01-01

    Observation of conoscopic figures through a special microscope is widely used as an experimental method for determination of optical properties of anisotropic materials. The conoscopic figure appears when a divergent light passes through an anisotropic material sandwiched between crossed polarizers. The complex pattern of bright and dark areas appears due to different polarization states of light. The pattern gives information about optical axes and birefringence of the material and allows for deduction of microscopic structures at the origin of such properties. Due to the complexity of the figure, the method is often used following recipes. This contribution presents a series of experiments that provide students with experiences needed for construction and comprehension of optical phenomena that contribute to the complexity of the conoscopic figure.

  11. Sexual attitudes as correlates of sexual details in human figure drawing.

    Science.gov (United States)

    Przybyla, D P; Byrne, D; Allgeier, E R

    1988-02-01

    The hypothesis that sexual attitudes, as measured by the Sexual Opinion Survey, are related to the explicitness with which nude figures are drawn was examined. The presence or absence of various sexual and nonsexual anatomical features, as well as length and width measurements, were assessed in the drawing of nudes by 17 male and 23 female undergraduates. Individuals with relatively positive sexual attitudes (erotophiles), as compared with individuals with relatively negative attitudes (erotophobes), were more likely to include such details as a glans, a urinary meatus, and chest hair on male figures and pubic hair and nipples on female figures. Positive sexual attitudes were also associated with drawing figures with longer and wider penises, breasts, testicles, and mons. Relationships between sexual attitudes and the drawing of nonsexual body parts were generally not significant. The results are discussed in terms of the pervasive generality of sexual attitudes in influencing quite varied sex-related behaviors.

    Breath figures have been formed by the direct breath figure method on polymethyl methacrylate electrode sand hexagonal oriented holes with 0.5- to 10- μm2 surface area have been created. Deposition of materials on the electrodes has been performed by the spray-coating method. polythiophene (PTh) nanoparticles, polythiophene-graphene oxide (PTh-GO) and polythiophene-reduced graphene oxide (PTh-G) nanocomposites were synthesized by emulsion polymerization, while characterization of synthetic materials have been carried out by Fourier transform infrared, Χ-ray diffraction, transmission electron microscopy, UV-Vis spectroscopy and field emission scanning electron microscopy techniques. Also, the electrochemical properties of the designed electrodes were investigated by cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy techniques. Specific capacitance of porous electrodes coated by PTh nanoparticles, PTh-GO and PTh-G nanocomposites were calculated from cyclic voltammetry curves at 5 mV/s scan rate, andthe values are 3.5 F/g, 16.39 F/g, and 28.68 F/g, respectively. Also, the energy density of each electrode at 5 mV/s scan rate has been calculated and the results show that incorporation of GO and G nanolayers with PTh nanoparticles enhances the electrochemical properties of electrodes.

  19. The equivalent width as a figure of merit for XPS narrow scans

    International Nuclear Information System (INIS)

    Singh, Bhupinder; Velázquez, Daniel; Terry, Jeff; Linford, Matthew R.

    2014-01-01

    Highlights: • We introduce a new figure of merit for XPS narrow scans: the equivalent width (EW XPS ). • EW XPS is less subjective and involves lesser user bias than traditional peak fitting. • EW XPS is responsive to changes in chemical states of materials. • EW XPS could be used for quality control and comparing spectra from similar samples. • EW XPS has the potential to be part of an expert software system for machine interpretation of spectra. - Abstract: X-ray Photoelectron Spectroscopy (XPS) is a widely used surface analytical tool that provides information about the near surface regions of materials. And while indispensable for XPS data analysis, peak fitting of narrow scans is often a fairly subjective exercise. Herein we introduce the equivalent width (EW) as an additional and less subjective figure of merit for XPS narrow scans. We believe that this parameter will prove particularly useful for analyzing series of similar or nominally identical spectra, perhaps as a component of an expert software system for the machine interpretation of spectra. It also appears to be useful, shedding light on the chemical state of materials, when additional information about a sample is known. The EW XPS is simply defined as the area of a narrow scan divided by the height of the maximum of its peak envelope. To limit any ambiguity in EW XPS for a series of spectra, we may also list the peak position of the maximum of the envelope (PE max ). The potential usefulness and limitations of the EW XPS and PE max parameters are demonstrated by their application to the narrow scans of: (i) four sets of ozone-treated carbon nanotubes (EW XPS ∼ 2.11–2.16 eV for a Shirley background, and up to 2.88 eV for no background, PE max ∼ 284.4–284.5 eV), (ii) a series of silicon wafers with different oxide thicknesses (EW XPS ∼ 1.5–2.8 eV, PE max ∼ 99–103 eV), (iii) hydrogen-terminated silicon before and after derivatization with pentyl groups, and after annealing of

  20. First and second language child speakers of Afrikaans’s knowledge of figurative language

    Directory of Open Access Journals (Sweden)

    Van der Merwe, Kristin

    2008-12-01

    Full Text Available This article reports on a study that compared the knowledge of figurative language in first (L1 and second language (L2 speakers of Afrikaans, aged 8 to 10. To assess comprehension of figurative language, 25 idioms were initially presented without context; only if the child gave an incorrect interpretation was the idiom placed in context. There was no statistically significant difference between the comprehension of idioms by the two language groups and they gave comparable numbers of literal interpretations. Providing context was beneficial to both groups. In the simile completion task, the child had to give the last word of a simile read to him by the researcher. This proved easier for both groups than the idiom task, but still no significant differences were found between the two groups. The results imply that the extent to which a child is aware of the existence of figurative language (i.e., that what is said is not always what is meant possibly has a greater influence on his/her figurative language skills than does the amount of exposure to figurative language used by others. This implies that an awareness of figurative language as well as the specific meaning of idioms and similes needs to be taught explicitly, regardless of whether the child is an L1 or L2 learner.

  1. Readability of the Translation of Figure of Speech in Srimad Bhagavatam From English Into Indonesian

    2017-01-01

    Full Text Available The research is a descriptive translation study focusing on the methods and ideology of translation of figure of speech used in the text of Srimad Bhagavatam into Indonesian. It departed from a translation paradigm that considered Srimad Bhagavatam as a product, and the impact of the methods and ideology applied to the readability level of figure of speech translation contained in Srimad Bhagavatam from English to Indonesian. This is a library study and the method used in collecting the data is observation, by reading the studied text carefully on the sentences that contain figure of speech. Data collection technique used is a qualitative one, namely by determining and explaining the methods and ideology embraced by the translator in translating the figure of speech. To view the translation readability level, three informants are involved to complete a questionnaire containing about the readability level of translation. This study shows that the ideology held by the translator is domestication by applying a communicative method of translation on most sentences with figure of speech. Overall, all translation methods used by the translator has a positive impact on the readability level of figure of speech translation from English into Indonesian.

  2. Spatio-temporal dynamics of impulse responses to figure motion in optic flow neurons.

    Directory of Open Access Journals (Sweden)

    Yu-Jen Lee

    Full Text Available White noise techniques have been used widely to investigate sensory systems in both vertebrates and invertebrates. White noise stimuli are powerful in their ability to rapidly generate data that help the experimenter decipher the spatio-temporal dynamics of neural and behavioral responses. One type of white noise stimuli, maximal length shift register sequences (m-sequences, have recently become particularly popular for extracting response kernels in insect motion vision. We here use such m-sequences to extract the impulse responses to figure motion in hoverfly lobula plate tangential cells (LPTCs. Figure motion is behaviorally important and many visually guided animals orient towards salient features in the surround. We show that LPTCs respond robustly to figure motion in the receptive field. The impulse response is scaled down in amplitude when the figure size is reduced, but its time course remains unaltered. However, a low contrast stimulus generates a slower response with a significantly longer time-to-peak and half-width. Impulse responses in females have a slower time-to-peak than males, but are otherwise similar. Finally we show that the shapes of the impulse response to a figure and a widefield stimulus are very similar, suggesting that the figure response could be coded by the same input as the widefield response.

  3. Public figure announcements about cancer and opportunities for cancer communication: a review and research agenda.

    Noar, Seth M; Willoughby, Jessica Fitts; Myrick, Jessica Gall; Brown, Jennifer

    2014-01-01

    Announcements by public figures and celebrities about cancer diagnosis or death represent significant events in public life. But what are the substantive effects of such events, if any? The purpose of this article is to systematically review studies that examined the impact of public figure cancer announcements on cancer-oriented outcomes. Using comprehensive search procedures, we identified k = 19 studies that examined 11 distinct public figures. The most commonly studied public figures were Jade Goody, Kylie Minogue, Nancy Reagan, and Steve Jobs, with the most common cancers studied being breast (53%), cervical (21%), and pancreatic (21%) cancer. Most studies assessed multiple outcome variables, including behavioral outcomes (k = 15), media coverage (k = 10), information seeking (k = 8), cancer incidence (k = 3), and interpersonal communication (k = 2). Results fairly consistently indicated that cancer announcements from public figures had meaningful effects on many, if not most, of these outcome variables. While such events essentially act as naturally occurring interventions, the effects tend to be relatively short term. Gaps in this literature include few contemporary studies of high-profile public figures in the United States and a general lack of theory-based research. Directions for future research as well as implications for cancer communication and prevention are discussed.

    2009-05-01

    Full Text Available Bien que l’iconographie wordsworthienne s’attache à représenter le poète en promeneur solitaire, les paysages qu’il retrace lui-même dans le Prélude de 1805 sont fort peuplés. De multiples personnages — qu’il faudra bien appeler figures — animent ses paysages. Ils les animent au sens propre du terme : c’est-à-dire qu’ils conduisent le mouvement dont les paysages wordsworthiens sont à la fois le produit et la scène. Ces figures, loin de faire de la figuration, donc, configurent, dans un jeu typiquement wordsworthien d’activité passive, la nouvelle vision du monde qui se trame dans ces paysages. Ils effectuent et relayent les principes de la poétique wordsworthienne — combinaison, rayonnement, exaltation — par laquelle “la révolution copernicienne” du romantisme a “lieu”.

  13. ‘Farm’ Animal Metaphors in Malay and Arabic Figurative Expressions: Implications for Language Learning

    Directory of Open Access Journals (Sweden)

    Sabariah MD Rashid

    2012-11-01

    Full Text Available Animals are commonly used in figurative expressions, such as proverbs and idioms. Their features, characteristics, and/or behaviours are employed as metaphors to convey certain meanings. This study sought to examine animal metaphors of Malay and Arabic figurative expressions.  Data examined comprised Malay figurative expressions such as simpulan bahasa (two-word idioms and peribahasa (proverbs, as well as Arabic figurative expressions such as istiarah (proverbs containing ‘farm’ animals, such as cow, donkey, horse and goat. The analysis focused on the description of animal images used in the expressions and their connotations. Findings of the study revealed some similarities and differences, in terms of the images and connotations used in the expressions of the two languages, which may be attributed to cultural differences. The differences reflected in the Malay and Arabic figurative expressions may contribute to the difficulty in grasping the meanings of the expressions amongst learners of these languages.Thus, it is essential that learners of each language be exposed to the elements related to the cultural differences of the two languages to help them understand the expressions better and become effective language learners.

    The biography of historical figures is often fascinating to be known. Everything about their character, work, invention, and personal life sometimes are presented in their biography. The social and family relationships among historical figures also put into concern, especially for political figures, heroes, kings or persons who have ever been ruled a monarchy in their past. Some biographies can be found in Wikipedia as articles. Most of the social and family relationship contents of these figures are not completely depicted due to a various article’s contributors and sources. Fortunately, the missing relatives of a person might reside in the other figures’ biography in different pages. Each Wikipedia article has metadata which represents its essential information of content. By processing the metadata obtained from DBpedia and composing the inferencing rules (in the form of ontology) to identify the relationships content, it can generate several new inferred facts that complement the existing relationships. This work proposes a methodology for finding missing relationships among historical figures using inference rules in an ontology. As a result, our method can present new facts about the relationships that absent in the existing Wikipedia articles.

    In this work 3D surface scans of wounds are used to obtain several measurement including wound top area, true surface area (rue area), depth, and volume for the purpose of assessing the progress of ulcer wounds throughout treatment. KONICA MINOLTA 910 laser scanner is used to obtain the surface scans. The algorithm for estimating top area and true surface area from surface scan can reduce the inaccuracy that might result when using manual method. Two methods for solid construction and volume computation were considered; namely mid-point projection and convex hull approximation (Delaunay tetrahedralization). The performance of convex hull approximation method for volume estimation is improved by performing surface subdivision prior to the approximation. The performance of these algorithms on different patterns of simulated wound models is presented. Furthermore the algorithms are tested in two molded wounds printed using rapid prototyping (RP) technique.

    Many exoplanets have been observed close to their parent stars with orbital periods of a few days. As for the major satellites of the Jovian planets, the figure of these planets is expected to be strongly shaped by tidal forces. However, contrary to solar system satellites, exoplanets may present high values for the obliquity and eccentricity due to planetary perturbations, and may also be captured in spin-orbit resonances different from the synchronous one. Here we give a general formulation of the equilibrium figure of those bodies that makes no particular assumption on the spin and/or orbital configurations. The gravity field coefficients computed here are well suited for describing the figure evolution of a body whose spin and orbit undergo substantial variations in time.

  18. Universal Curve of Optimum Thermoelectric Figures of Merit for Bulk and Low-Dimensional Semiconductors

    This paper is a contribution to the Physical Review Applied collection in memory of Mildred S. Dresselhaus. Analytical formulas for thermoelectric figures of merit and power factors are derived based on the one-band model. We find that there is a direct relationship between the optimum figures of merit and the optimum power factors of semiconductors despite of the fact that the two quantities are generally given by different values of chemical potentials. By introducing a dimensionless parameter consisting of the optimum power factor and lattice thermal conductivity (without electronic thermal conductivity), it is possible to unify optimum figures of merit of both bulk and low-dimensional semiconductors into a single universal curve that covers many materials with different dimensionalities.

    In a preprint by Montgomery (https://people.ucsc.edu/~rmont/Nbdy.html), the author attempted to prove the existence of a shape space figure-8 solution of the Newtonian three body problem with two equal masses (it looks like a figure 8 in the shape space, which is different from the famous figure-8 solution with three equal masses (Chenciner and Montgomery 2000 Ann. Math. 152 881-901)). Unfortunately there is an error in the proof and the problem is still open. Consider the α-homogeneous Newton-type potential, 1/rα, using action minimization method, we prove the existence of this solution, for α \\in (1, 2) ; for α=1 (the Newtonian potential), an extra condition is required, which unfortunately seems hard to verify at this moment.

    The grey pottery figure manufactured in the Western-Han Dynasty (175-118 B.C.) and the clay gathered from the same site of Beidongshan in Xuzhou have been studied by X-ray Diffration (XRD), X-ray Fluorescence (XRF), and Moessbauer spectroscopy. They were simultaneously fired under the same conditions in different atmospheres at various temperature up to 1100degC. This study deals with the original firing atmosphere, original firing temperature and its provenance. The information mentioned above can be inferred from the method of the refiring pottery and the firing clay. The results of the original firing temperature deduced from both of them are in goodself agreement. It is found that the values of the Moessbauer parameters for the unrefired pottery figure are approximately the same as those for the clay fired at 950degC for five hours in a reduced atmosphere. The XRF analysis confirmed the locality of this pottery figure. (orig.)

Large statistical divergence is educed in the absolute indexes of class force which needs the differentiated approach in the process of correction.

  2. Vagabond Figures in Slovenian Visual Art and Literature at the Beginning of the Twentieth Century

    2011-07-01

    Full Text Available The article explores the relationship between visual and literary motifs in Slovenian painting (and illustration, graphics, and drawing and literature (both prose and poetry at the beginning of the twentieth century. It uses examples to show the popularity and rich variety of vagabond figures and their transformations and reciprocity at the level of the painting/text. However, a distinctive feature of this article is that it places the subject within the context of hermeneutics, a method that has not been used in Slovenian art history. In addition, it also reveals the symbolic complexity of the vagabond figure in the context of writers, other works, and social-historical circumstances. The emphasis is placed on artists that showed enthusiasm for this figure as a subject during the Belle Époque and also those that followed the very popular bohemian lifestyle in their everyday lives. The reception of Slovenian folk and traditional motifs from the past produced visual and semantic oscillation in which the phenomena of vagabond figures were systematized and interpreted. Many painters (e.g., Gvidon Birolla, and Maksim Gaspari and writers (e.g., Oton Župančič, Cvetko Golar, and Ivan Cankar clung to the Slovenian tradition with romantic overtones and, in line with their artistic atmosphere, integrated vagabond figures into typical Slovenian landscapes or environments. Some of them followed Symbolism and modernized the figures with autobiographical references (e.g., Fran Tratnik. The situation among the youngest generation of artists in particular showed that they managed to “escape” from copying traditional motifs and instead used them in a modern form in the “here and now” (e.g., Ivan Cankar. The discrepancy between the lack of the vagabond theme in oil painting and strong diversification in illustration, drawing, graphics, and literature could be explained by consumers’ perceived difference between “high” and “popular” art.

    In the classical theory of thermoelectricity, the performance integrals for a fully self-compatible material depend on the dimensionless figure of merit zT. Usually these integrals are evaluated for constraints z = const. and zT = const., respectively. In this paper we discuss the question from a mathematical point of view whether there is an optimal temperature characteristics of the figure of merit. We solve this isoperimetric variational problem for the best envelope of a family of curves z(T)T.

    2013-12-01

    Full Text Available The essay explains Giovanni Verga’s Malavoglia according to the narrative theory of Franz Karl Stanzel, arguing that the novel provides an example of the figural narrative situation. The figuralization (or reflectorization of Malavoglia is achieved mainly by the so-called (the definition is Ann Banfield’s non-reflective consciousness, that is, by the perceptive interplay of characters, independent of the intervention of an actual narrator. Such a methodological point of view implies a revision of some typological features of modernist novel, which has been too often interpreted only through texts of the “northern” Flaubert-James-Joyce-Woolf line.

    Full Text Available This work attempts to rehabilitate Donna Haraway’s (1991 figure of the cyborg to increase the possibilities of alliances between transnational feminism and cyborg or technoscience feminism. Haraway’s cyborg offers little impetus for political investment and coalition building. This work develops an optional prosthesis of responseability for the cyborg figuration, one that enables the cyborg to invest locally. This ethic of response-ability is developed via the work of Mary Strine (1989, Adrienne Rich (1984 and Aimee Carillo Rowe (2005. This supplementary ethic grafts a “collectivist conscience” onto the permeable being of the cyborg, encouraging alliance- and coalitionbuilding.

    Accelerator mass spectrometry radiocarbon ages have been taken for a test suite of small samples of material removed from some of the ``beeswax`` art figures found in rock shelters in northern Australia. The results indicate that we can reliably date this unique form of rock art with no noticeable damage. We had not expected to find figures of any great antiquity, and so were surprised to find that the ages obtained spanned the time period from the recent past to about 4000 BP. (Author).

    2014-01-01

    As part of ongoing development efforts at MSFC, we have begun to investigate mounting strategies for highly nested xray optics in both full-shell and segmented configurations. The analytical infrastructure for this effort also lends itself to investigation of active strategies. We expect that a consequence of active figure control on relatively thin substrates is that errors are propagated to the edges, where they might affect the effective precision of the mounting points. Based upon modeling, we describe parametrically, the conditions under which active mounts are preferred over fixed ones, and the effect of active figure corrections on the required number, locations, and kinematic characteristics of mounting points.

  12. Wave-equation dispersion inversion of surface waves recorded on irregular topography

    2017-08-17

    Significant topographic variations will strongly influence the amplitudes and phases of propagating surface waves. Such effects should be taken into account, otherwise the S-velocity model inverted from the Rayleigh dispersion curves will contain significant inaccuracies. We now show that the recently developed wave-equation dispersion inversion (WD) method naturally takes into account the effects of topography to give accurate S-velocity tomograms. Application of topographic WD to demonstrates that WD can accurately invert dispersion curves from seismic data recorded over variable topography. We also apply this method to field data recorded on the crest of mountainous terrain and find with higher resolution than the standard WD tomogram.

    According to the metaphorical framing model, the use of metaphors in discussing an issue influences recipients' understanding and assessment of that issue. In a recent study, participants read a text referring to a city's crime problem either as a beast or a virus and then proposed counter-measures for that problem. Participants' suggestions differed depending on the metaphor they had read. This replication matched the original procedure regarding the content of the rhetorical figures (beast vs virus), the topic under focus (crime) and the measurement of the dependent variable (open-end format to collect participants' proposals). The procedure differed from the original with respect to language (German instead of English) and by including the formal type of rhetorical figure (metaphor or simile) as a factor. A systematic influence of the content of the figure on subjects' proposals was observed. Presenting the rhetorical figure as a metaphor or a simile had no effect. Taken together, we were able to replicate the main effect of the original study. Metaphors do indeed frame reasoning.

  4. High figure-of-merit SOI power LDMOS for power integrated circuits

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available The structural modifications in the conventional power laterally diffused metal-oxide-semiconductor field-effect transistor (LDMOS are carried out to improve the breakdown voltage, on-resistance, gate-charge and figure-of-merits of the device with reduced cell pitch. The modified device has planer structure implemented on silicon-on-insulator which is suitable for low to medium voltage power integrated circuits. The proposed LDMOS consists of two gate electrodes placed vertically in two separate trenches build in the drift region and single source and drain contacts are taken on the top. The trench structure reduces the electric field inside the drift region and allow increased drift layer doping concentration leading to higher breakdown voltage, lower specific on-resistance, reduced gate-drain charge, and substantial improvement in the figure-of-merits. Using two-dimensional simulations, the performance of the proposed LDMOS is optimized and results are compared with the conventional LDMOS. Our simulation results show that the proposed device exhibits 110% higher breakdown voltage, 40% reduction in cell pitch, 19% lower specific on-resistance, 30% lower gate-to-drain charge leading to 5.5 times improvement in Baliga's figure-of-merit and 43% reduction in dynamic figure-of-merit over the conventional device.

  10. Interplay of Multisensory Processing, Attention, and Consciousness as Revealed by Bistable Figures

    Directory of Open Access Journals (Sweden)

    Su-Ling Yeh

    2011-10-01

    Full Text Available We examined the novel crossmodal semantic congruency effect on bistable figures in which a static stimulus gives rise to two competing percepts that alternate over time. Participants viewed the bistable figure “my wife or my mother-in-law” while listening to the voice of an old woman or a young lady speaking in an unfamiliar language. They had to report whether they saw the old woman, the young lady, or a mixed percept. Robust crossmodal semantic congruency effects in the measures of the first percept and the predominance duration were observed. The possibilities that the participants simply responded to, and/or that they fixed at the location in favor of, the percept congruent with the sound that they happened to hear were ruled out. When the participants were instructed to maintain their attention to a specific view, a strong top-down modulation on the perception of bistable figure was observed, although the audiovisual semantic congruency effect still remained. These results thus demonstrate that top-down attention (ie,, selection and/or voluntary control modulates the audiovisual semantic congruency effect. As the alternating percepts in bistable figures indicate competition for conscious perception, this study has important implications for the multifaceted interactions between multisensory processing, attention, and consciousness.

  14. Satiation or availability? Effects of attention, memory, and imagery on the perception of ambiguous figures

    Science.gov (United States)

    Horlitz, Krista L.; O'Leary, Ann

    1993-01-01

    The prolonged-inspection technique has been used to demonstrate effects of satiation on the perception of ambiguous figures. We propose that the inspection phase, in which subjects view an unambiguous version of the stimulus prior to observing the ambiguous figure, does not create neural fatigue but rather provides a context in which the alternative percept is apprehended and gains perceptual strength through processes such as imagination or memory. The consequent availability of the alternative organization drives the perceptual phenomena that have been thought to reflect satiation. In Experiment 1, we demonstrated that (1) preexperimental exposure to the target figures and (2) allocation of attention to the inspection figures were both necessary in order to obtain results similar to those predicted by the satiation model. In Experiment 2, we obtained similar results, finding that effects of prior inspection were greater the greater the amount and availability of information regarding the alternative percept during the inspection phase. Subjects who generated visual images of the noninspected alternative during inspection yielded results comparable to those from subjects to whom both versions were presented visually.

    This article asks how public pedagogical texts mobilise particular meanings about whose bodies/minds matter or figure? How do they articulate particular affective investments, desires, and values related to our everyday understanding of invisible and visible impairments, and the ways in which discourses of "normalcy" are taught?

    As Amanda Diekman and Sarah Murnen (2004) note, studies of "nonsexist" children's books tend to focus on girls performing stereotypically masculine behaviors without consideration of how boy characters perform gender (p. 381); however, this narrow focus on girl figures in the identification of nonsexist works has two side-effects:…

  20. Science in the Making: Right Hand, Left Hand. II: The duck-rabbit figure.

    2010-01-01

    The BBC television programme Right Hand, Left Hand, broadcast in August 1953, showed a version of the duck-rabbit figure and asked viewers to say what they could see in the “puzzle picture”. Nearly 4,000 viewers described the image, and the answers to those questions have recently been found and analysed. The programme probably used the same version of the figure as appeared in Wittgenstein's Philosophical Investigations, which had been published a month or two previously. Although Dr Jacob Bronowski, the presenter of the programme, had suspected that left- and right-handers might differ in their perception of the figure, since they might scan it from different sides, in fact there is no relationship in the data between six measures of lateralisation and a propensity for seeing a duck or a rabbit. However the large data set does show separate effects of both age and sex on viewing the figure, female and older viewers being more likely to report seeing a rabbit (although a clear majority of viewers reported seeing a duck). There was also a very significant tendency for female viewers to use more typical descriptions of the duck, whereas males used a wider variety of types.

    Anti-fat prejudice (weight bias, obesity stigma) is strong, prevalent, and increasing in adults and is associated with negative outcomes for those with obesity. However, it is unknown how early in life this prejudice forms and the reasons for its development. We examined whether infants and toddlers might display an anti-fat bias and, if so, whether it was influenced by maternal anti-fat attitudes through a process of social learning. Mother-child dyads (N=70) split into four age groups participated in a preferential looking paradigm whereby children were presented with 10 pairs of average and obese human figures in random order, and their viewing times (preferential looking) for the figures were measured. Mothers' anti-fat prejudice and education were measured along with mothers' and fathers' body mass index (BMI) and children's television viewing time. We found that older infants (M=11months) had a bias for looking at the obese figures, whereas older toddlers (M=32months) instead preferred looking at the average-sized figures. Furthermore, older toddlers' preferential looking was correlated significantly with maternal anti-fat attitudes. Parental BMI, education, and children's television viewing time were unrelated to preferential looking. Looking times might signal a precursor to explicit fat prejudice socialized via maternal anti-fat attitudes. Copyright © 2015 Elsevier Inc. All rights reserved.

    Art exploration is a complex process conditioned by factors at different levels and includes both basic visual principles and complex cognitive factors. The human figure is considered a critical factor attracting the attention in art painting. Using an eye-tracking methodology, the goal of this study was to explore different elements of the human figure performing an action (face and body parts in action) in complex social scenes characterized by different levels of social interaction between agents depicted in scenes (individual vs. social). The sample included 44 laypersons, and the stimuli consisted of 10 fine art paintings representing the figurative style of classical art. The results revealed different scanning patterns of the human figure elements related to the level of social interaction of agents depicted in the scene. The agents' face attracted eye movements in social interaction scenes while the agents' body parts attracted eye movements only when the agents were involved in individual actions. These processes were confirmed specifically in participants with high empathic abilities who became immediately fixated on faces to develop a mimetic engagement with other agents. Future studies integrating other measures would help confirm the results obtained and strengthen their implication for embodiment processes.

  11. Equilibrium Figures inside the Dark-Matter Ring and the Shapes of Elliptical Galaxies

    Directory of Open Access Journals (Sweden)

    Kondratyev B. P.

    2015-12-01

    Full Text Available We solve the general problem of the theory of equilibrium figures and analyze two classes of liquid rotating gravitating figures residing inside a gravitating ring or torus. These figures form families of sequences of generalized oblate spheroids and triaxial ellipsoids, which at the lower limit of the tidal parameter α = 0 have the form of the Maclaurin spheroids and the Jacobi ellipsoids. In intermediate cases 0 < α ≤ αmax each new sequence of axisymmetric equilibrium figures has two non-rotating boundary spheroids. At the upper limit αmax/(πGρ = 0.1867 the sequence degenerates into a single non-rotating spheroid with the eccentricity ecr ≈ 0.96 corresponding to the flattening limit of elliptical galaxies (E7. We also perform a detailed study of the sequences of generalized triaxial ellipsoids and find bifurcation points of triaxial ellipsoids in the sequences of generalized spheroids. We use this method to explain the shapes of E-galaxies. According to observations, very slowly rotating oblate E-type galaxies are known that have the shapes, which, because of instability, cannot be supported by velocity dispersion anisotropy exclusively. The hypothesis of a massive dark-matter outer ring requires no extreme anisotropy of pressure; it not only explains the shape of these elliptical galaxies, but also sheds new light on the riddle of the ellipticity limit (E7 of elliptical galaxies.

  12. The principal moments of inertia calculated with the hydrostatic equilibrium figure of the Earth

    Directory of Open Access Journals (Sweden)

    Chengjun Liu

    2017-05-01

    Full Text Available As an indication of the Earth's mass distribution, the principal moments of inertia (PMOI, i.e., A, B, C of the Earth are the basic parameters in studies of the global dynamics of the earth, like earth nutation, and the geophysics. From the aspect of observation, the PMOI can be calculated from the spherical coefficients of observed gravity field. In this paper, the PMOI are calculated directly according to its definition with the figures of the Earth's interior derived by a generalized theory of the hydrostatic equilibrium figure of the Earth. We obtain that the angle between the principal axis of the maximum moment of PMOI and the rotational axis is 0.184°, which means that the other two principal axes are very closely in the equatorial plane. Meanwhile, B-A is 1.60 × 10−5 MR2, and the global dynamical flattening (H is calculated to be 3.29587 × 10−3, which is 0.67% different from the latest observation derived value Hobs(3.273795 × 10−3 (Petit and Luzum, 2010, and this is a significant improvement from the 1.1% difference between the value of H derived from traditional theories of the figure of the Earth and the value of Hobs. It shows that we can calculate the PMOI and H with an appropriate accuracy by a generalized theory of the hydrostatic equilibrium figure of the Earth.

    To examine the association of adolescents' wanting to look like figures in the media with physical activity levels. Cross-sectional mailed survey of 11,606 boys and girls, between the ages of 9 and 16 years, participating in the Growing Up Today Study in 1997. Participants reported detailed information on physical activities over the previous year, and the degree to which they were trying to look like same-sex images in television, movies, and magazines. We performed linear regression modeling to assess the independent effects of wanting to look like figures in the media on physical activity levels. Mean total weekly physical activity levels were 12.4 hours in girls and 15.2 hours in boys. 3019 (46%) girls and 1360 (27%) boys reported making at least some effort to look like figures in the media. Adjusted for age, body mass index, sexual maturity rating, and race/ethnicity, total physical activity levels were higher by 0.7 (95% CI 0.5-0.9) and 1.2 (95% CI 0.9-1.6) hours per week in girls and boys, respectively, for every 1 (out of 5) category increase in wanting to look like figures in the media. Adjustment for intrapersonal and social confounders modestly attenuated the associations. Wanting to look like figures in the media was associated with higher physical activity levels among older children and adolescents, independent of other personal and social influences. These data suggest that television, movie, and magazine industries should be encouraged to cultivate and reinforce realistic and healthy norms of physical activity and body image.

  16. Medical and surgical practice as represented in cultural figures from the pre-conquest Mesoamerican territories.

    Goodrich, James Tait; Ponce de Leon, Fernando Chico

    2010-07-01

    To review medical and surgical practices in pre-Conquest Mexico in the Olmec and Mayan regions and areas of West Mexico as depicted on terra-cotta, stone, and stelae figures. A search was undertaken to locate and describe interesting and unusual medical and surgical figures from the pre-Conquest period of Mesoamerica. Using the details of these figures, descriptions of medical and surgical practices are outlined. Neurosurgery was not a defined or developed surgical technique in the Mesoamerican territories; nevertheless, elements of medical and surgical practice were clearly widespread. Two important cultures that developed in the pre-Conquest period were the Olmec and the Mayan civilizations. Both cultures had a written language; however, most of their manuscripts were destroyed by the Spanish during the Conquest in the 16th and 17th centuries. These early cultures were rich in sculpted artifacts: stone and terra-cotta figures depict scenes that reveal much about this period and, in particular, early medical and neurosurgical practice. A similar but not quite so advanced civilization was also developing in West Mexico in what are now the States of Colima, Nayarit, and Jalisco. Sculptures and figures from these periods illustrate some of the early medical and surgical practices and provide interesting insights into the rich and varied cultures of these Mesoamerican territories. The focus of this article is on two important cultures and periods: the Olmec (1200 bc-200 ad) and the classical Mayan (200 ad-900 ad) societies, as well as the West Mexico cultures (100 bc-500 ad). Review of the data and images reveals a sophisticated society clearly interested in detailing various medical and surgical practices in Mesoamerica and hints at some early neurosurgical practices in this era.

  20. Atlas-free surface reconstruction of the cortical grey-white interface in infants.

    Directory of Open Access Journals (Sweden)

    François Leroy

    Full Text Available BACKGROUND: The segmentation of the cortical interface between grey and white matter in magnetic resonance images (MRI is highly challenging during the first post-natal year. First, the heterogeneous brain maturation creates important intensity fluctuations across regions. Second, the cortical ribbon is highly folded creating complex shapes. Finally, the low tissue contrast and partial volume effects hamper cortex edge detection in parts of the brain. METHODS AND FINDINGS: We present an atlas-free method for segmenting the grey-white matter interface of infant brains in T2-weighted (T2w images. We used a broad characterization of tissue using features based not only on local contrast but also on geometric properties. Furthermore, inaccuracies in localization were reduced by the convergence of two evolving surfaces located on each side of the inner cortical surface. Our method has been applied to eleven brains of one- to four-month-old infants. Both quantitative validations against manual segmentations and sulcal landmarks demonstrated good performance for infants younger than two months old. Inaccuracies in surface reconstruction increased with age in specific brain regions where the tissue contrast decreased with maturation, such as in the central region. CONCLUSIONS: We presented a new segmentation method which achieved good to very good performance at the grey-white matter interface depending on the infant age. This method should reduce manual intervention and could be applied to pathological brains since it does not require any brain atlas.

    2013-05-01

    Full Text Available In this work, we analyze different configurations of a thermoelectric system (TES composed of three thermoelectric generators (TEGs. We present the following considerations: (a TES thermally and electrically connected in series (SC; (b TES thermally and electrically connected in parallel (PSC; and (c parallel thermally and series electrical connection (SSC. We assume that the parameters of the TEGs are temperature-independent. The systems are characterized by three parameters, as it has been showed in recent investigations, namely, its internal electrical resistance, R, thermal conductance under open electrical circuit condition, K, and Seebeck coefficient α. We derive the equivalent parameters for each of the configurations considered here and calculate the Figure of Merit Z for the equivalent system. We show the impact of the configuration of the system on Z, and we suggest optimum configuration. In order to justify the effectiveness of the equivalent Figure of Merit, the corresponding efficiency has been calculated for each configuration.

  2. Radioactive indium labelling of the figured elements of blood. Method, results, applications

    International Nuclear Information System (INIS)

    Ducassou, D.; Nouel, J.P.

    Following the work of Thakur et al. the authors became interested in red corpuscle, leucocyte and platelet labelling with indium 111 or 113m (8 hydroxyquinolein-indium). For easier labelling of the figured elements of blood the technique described was modified. The chelate is prepared by simple contact at room temperature of indium 111 or 113m chloride and water-soluble 8 hydroxyquinolein sulphate, in the presence of 0.2M TRIS buffer. The figured element chosen suspended in physiological serum is added directly to the solution obtained, the platelets and leucocytes being separated out beforehand by differential centrifugation. While it gives results similar to those of Thabur et al. the method proposed avoids the chloroform extraction of the radioactive chelate and the use of alcohol, liable to impair the platelet regation capacity [fr

    The present study tested the direct effect of watching thin-ideal focused television aimed at (young) adults on body dissatisfaction in preadolescent girls (9-12 years old). A within-subject design was used in which the girls (N=60) were tested three times. They watched three movie clips in random order that were either focused explicitly (thin-ideal program) or indirectly (soap opera) on the thin ideal or were neutral in content. Afterwards, they filled out questionnaires concerning their body dissatisfaction. Only older preadolescent girls (11-12 years old) showed greater body dissatisfaction after watching the thin-ideal focused television clip than after watching the neutral television clip. After watching thin-ideal focused television, they desired a thinner body figure than after watching neutral television. The findings imply that watching (adult) thin-ideal television directly affects the ideal body figure in older preadolescent girls. Copyright © 2010 Elsevier Ltd. All rights reserved.

    This work presents the study of crystalline texture of Zr-2.5%Nb pressure tubes (A, B and C); structural components of CANDU nuclear power reactors [1]. The study of texture was made using the RX diffraction technique, making measurements of direct pole figures [2], in a Phillips diffractometer with pole goniometer (IFIR-CONICET). The texture was determined calculating the coefficients of JJ Kearns [3]. The samples used correspond to transversal sections of the tubes, front and back, and were characterized making de measurements of five pole figures with Miller index (001), (100), (101), (102) and (110), in order to represent in a complete way the texture in the material. The calculated Kearns coefficients were compared with the specifications given by the designer of pressure tubes AECL [4] (author)

    2013-09-01

    Full Text Available Among the different rhetorical strategies of contemporary story, one stands out peculiarly in magazine journalism, the employment of Figures of Language as forms of enchantment and persuasion. Considering the proliferation of information on more immediate media, magazines like Veja and Época, objects of analysis of this study, produce a kind of text with more complex functions. Concomitantly pragmatic and poetic, the interpretive story intends to guide, to make knowing, thinking, feeling and deciding. There is an aesthetic work, of creation of an emotional ambience, in order that the raised arguments and propositions gain the adhesion of the reader. Thus, we aim to analyse the function of Figures of Language to understand and explain how the two most widely read magazines in the country weave meanings so penetrant.

    A statistical study of the detection process demonstrates that the free parameter is essential to compute the counting efficiency in both CIEMAT/NIST and TDCR methods. An analysis of the computed counting efficiencies shows the uselessness of old definition of the figure of merit. A new definition is required and we adopt the idea of taking quantities related with the output of the photomultiplier. In addition, we justify the application of the chemical quenching simulation with the electronic variation of the photomultiplier gain. Finally, we describe a new procedure to determine the figure of merit and the optimum ionization-quenching factor from the pulse spectrum of different radionuclides. The robustness of the new procedure is tested with three different sets of stopping power for low-energy electrons

    2010-01-01

    The multifarious issues of health and safety at work require multi-disciplinary skills, both in the risk assessment and in the subsequent definition and management of preventive measures, and this requires a renewed operational protocol that supports integration and co-operation between the technical prevention figures. Thus, between occupational physicians and technical advisers there should be a concrete and fruitful interaction, which should not be episodic or occasional, but a modus operandi systematic and constant. In this contribution is discussed as the technical prevention figures should be included in the Health and Safety Management System and should make a specific contribution in defining corporate policies on prevention. In particular it is outlined the role that the occupational physician may play in the development of prevention and health promotion activities within the strategies of corporate social responsibility.

  9. Figure Types in the AAS Journals: A Treasure Trove of Unmined Data

    Schwarz, Greg

    2013-01-01

    I present an analysis of the types of figures submitted to the AAS Journals as the prelude of a long term AAS project to capture more of the supporting data. Figures can be classified into 3 broad categories, diagrams, line art, and images. Diagrams are schematic, drawings, or illustrations and are meant to convey purely visual information. There is no intrinsic machine readable data underlying them. Line art and images, on the other hand, are snapshots of the larger underlying observational and model generated data sets. The advantages of including more data in a Virtual Observatory supported format is obvious for the reader but would also be an advantage for the author through greater visibility and thus higher citation counts. In this poster I present statistics from the August 2012 Astronomical Journal (V144 n2) and September 10th, 2012 Astrophysical Journal (v756 n2) issues and outline the near term challenges in capturing this "missing mass".

    Previous research has shown that bilinguals outperform monolinguals on a variety of tasks that have been described as involving executive functioning, but the precise mechanism for those effects or a clear definition for "executive function" is unknown. This uncertainty has led to a number of studies for which no performance difference between monolingual and bilingual adults has been detected. One approach to clarifying these issues comes from research with children showing that bilinguals were more able than their monolingual peers to perceive both interpretations of an ambiguous figure, an ability that is more tied to a conception of selective attention than to specific components of executive function. The present study extends this notion to adults by assessing their ability to see the alternative image in an ambiguous figure. Bilinguals performed this task more efficiently than monolinguals by requiring fewer cues to identify the second image. This finding has implications for the role of selective attention in performance differences between monolinguals and bilinguals.

    Nowadays heavy experimental efforts are focussed on doped oxide thermoelectrics to increase the thermopower and thermoelectric performance. We propose a high thermoelectric figure of merit for half-metallic SrTi1−xCoxO3 (x = 0, 0.125, 0.25, 0.375, and 0.5) in a superlattice with SrTiO3, which is stable at high temperatures and in an oxygen environment. The maximal value of Z hardly depends on the doping, while the temperature at which the maximum occurs increases with the Co concentration. The easy tunability from being an insulator to a half-metal under substitutional doping combined with the colossal figure of merit opens up great potential in the emerging field of spin-caloritronics.

  13. Assessment of the impact chemistry text and figures have on visually impaired students' learning

    Mayo, Provi M.

    Most of the literature fails to address how blind students visualize abstract science, specifically chemistry material. It also fails to discuss or access mental imageries of highly visual and abstract material and how blind students as well as the professors cope with this type of concepts in a science course. Chemistry texts and figures are being translated into braille and tactile paper for blind science students, yet there has not been an assessment of their impact on students' learning. This study describes what blind students visualize or understand when they read a text describing abstract chemistry material with words with high visual context; how their visualizations differ when they are reading the chemistry text from tactual perception versus reading a description in braille; and how blind students reconcile the discrepancy between their perception of molecular models from the text and tactual perception of the figures.

    The Medium-energy Electron-Ion Collider (MEIC) proposed by Jefferson Lab is designed to provide high polarization of both colliding beams. One of the unique features of JLab's MEIC is figure-8 shape of its rings. It allows preservation and control of polarization of all ion species including small-anomalous-magnetic-moment deuterons during their acceleration and storage. The figure-8 design conceptually expands the capability of obtaining polarized high-energy beams in comparison to conventional designs because of its property of having no preferred periodic spin direction. This allows one to control effectively the beam polarization by means of magnetic insertions with small field integrals. We present a complete scheme for preserving the ion polarization during all stages of acceleration and its control in the collider's experimental straights.

    Neutron diffraction is an excellent tool for pole figure measurement of rock samples. Due to high penetration depth of neutrons for most materials neutron diffraction represents an efficient tool to measure complete pole figures with reliable grain statistics even in coarse grained or inequi-granular materials. In the field of structural geology, the measurement of anisotropy of magnetic susceptibility is a standard technique to reveal the tectonic history of deformed rocks. The application of both techniques on still ongoing studies of Precambrian, Carboniferous and Quaternary rocks which are characterised by fundamental different tectonic evolutions and mineralogical compositions shows the wide field of relevance and importance of these methods in understanding tectonic processes in detail

    Structure of the Moon's Surface aims to assemble and marshal relevant matter, and to produce a largely unprejudiced text which brings lunar studies up to date and stresses the importance of certain features of the Moon which have frequently been disregarded in the past, largely because of lack of knowledge about them. The book contains 14 chapters organized into two parts. Part I reviews and summarizes important physical problems. These include the liberations of the moon; height determinations of points of the moon's surface; the figure of the moon; and the moon's temperature and atmosphere.

  18. Visual relations children find easy and difficult to process in figural analogies

    Analogical reasoning, the ability to learn about novel phenomena by relating it to structurally similar knowledge, develops with great variability in children. Furthermore, the development of analogical reasoning coincides with greater working memory efficiency and increasing knowledge of the entities and relations present in analogy problems. In figural matrices, a classical form of analogical reasoning assessment, some features, such as color, appear easier for children to encode and infer ...

    Full Text Available Thermoelectric effects arising in a sample placed in a measuring oscillating loop have been studied. It has been shown that asymmetric character of flowing current results in a volumetric bundle of induced Foucault currents and regions of Peltier heat release by thermoelectric sample which leads to increasing of irreversible heat losses recorded by measuring oscillating loop. The presence of this effect has caused the emergence of ingenious non-invasive method for recording of thermoelectric materials figure of merit.
