    Skedros, John G; Brand, Richard A

    2011-11-01

    This biographical sketch on Georg Hermann von Meyer highlights the interactions in the 1860s that von Meyer, a famous anatomist, had with Karl Culmann, a famous structural engineer and mathematician. The published papers from this interaction caught the attention of Julius Wolff and stimulated his development of the trajectorial hypothesis of bone adaptation--now called "Wolff's Law." The corresponding translations are provided: (1) von Meyer's 1867 paper that highlights the regularity of arched trabecular patterns in various human bones, and his discussions with Culmann about their possible mechanical relevance; and (2) Wolff's 1869 paper that first mentions the correspondence of stress trajectories in a solid, crane-like structure to the arched trabecular patterns in the proximal human femur. This biographical sketch on Georg Hermann von Meyer corresponds to the historic texts, The Classic: The Architecture of the Trabecular bone (by von Meyer), and The Classic: On the Significance of the Architecture of the Spongy Substance for the Question of Bone Growth. A preliminary publication (by Wolff) available at DOIs 10.1007/s11999-011-2041-5 , 10.1007/s11999-011-2042-4 . PMID:21901583

    Science.gov (United States)

    Olson, R E

    1986-12-01

    Wendell Griffith made an indelible impression on his students, his colleagues and the broad field of the nutrition sciences. He was the prototype of the physiological chemist studying intricate problems of intermediary metabolism in the whole animal or human body. His early scientific reports on choline and amino acid metabolism set a high standard for intellectual precision and literary clarity. Dr. Griffith's last research paper was entitled "The Present Knowledge of Methyl Groups in Nutrition" and appeared in Nutrition Reviews in 1968. In this paper he reviews the substance of figure 2, which depicts the advancement in knowledge of choline metabolism, methyl biosynthesis, and transmethylation during his career. It is fortunate that Dr. Griffith was able to witness many of the developments in a field that he had pioneered. If he were alive today, he would be delighted to see how much further this field has moved. Wendell Griffith was a complete man. He combined the traits of high intelligence with a selfless patience and kindness, uncommon in productive scientists. His lucid and absorbing lectures were a joy to his students. Furthermore, he was a mentor with warmth and charm in his relationships to his graduate students and young faculty members and was a superb role model for them. After they left his department he was most supportive. Part of his own rejuvenation, I am sure, occurred in the out-of-doors where he loved to garden, hike and fish. Griff did not grow old, or it seemed he did not. He died at the age of 72 in Baltimore from a brain tumor that was of relatively sudden onset, and is buried in Oak Hill cemetery in Kirkwood, MO, a suburb of St. Louis. He enriched the lives of all of us who had the good fortune to know him. Moreover, his work lives on to stimulate the minds of all serious students of biochemistry and nutrition. PMID:3543258

  19. Social change in the perspective of biographical reflection

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available The modern world is interpreted and described in terms of an autobiographical society, in which the fundamental issues of human life are resolved in the process of an individual decision and being involved in a peculiar type of a dialog. This dialog is more and more often a dialog with oneself and an author’s vision of the world created in the confrontation with virtual reality. In this epoch context the biography is taken into account as a tool for perceiving, understanding and describing the change of the world and the human’s place in the world. Even though, the biography has functioned in social life forever, only now with the epoch of individualization, and then virtualization of life, its formative character has been noticed. Who is the subject of (autobiography? Who is it aimed at as a message and testimony of life? How is it created? Why is it constructed? Who is it constructed by? And then the questions which are behind the autobiography in the theoretical sense – What is life? How do we discover it? What is the link between telling about life and living the life? How is the telling (living about a life connected with culture and history? How does reading (interpreting about life connect with telling about life and the truth about life? Social development phases coupled with transformations within biographical reflection have been distinguished: life in a traditional world – the culture of telling about life; the birth of individualism (the individualization of experience – the culture of describing life; the discovery of identity – the culture of reading about life; life in the net and cyberspace – the culture of constructing life; the new communalism – the culture of seeking the meaning of life. Every stage of biographical reflection enables us to distinguish new forms of creating, understanding and using it in both the humanities and social life, but also in ordinary people’s life.

  1. Robust Face Sketch Style Synthesis.

    Science.gov (United States)

    Shengchuan Zhang; Xinbo Gao; Nannan Wang; Jie Li

    2016-01-01

    Heterogeneous image conversion is a critical issue in many computer vision tasks, among which example-based face sketch style synthesis provides a convenient way to make artistic effects for photos. However, existing face sketch style synthesis methods generate stylistic sketches depending on many photo-sketch pairs. This requirement limits the generalization ability of these methods to produce arbitrarily stylistic sketches. To handle such a drawback, we propose a robust face sketch style synthesis method, which can convert photos to arbitrarily stylistic sketches based on only one corresponding template sketch. In the proposed method, a sparse representation-based greedy search strategy is first applied to estimate an initial sketch. Then, multi-scale features and Euclidean distance are employed to select candidate image patches from the initial estimated sketch and the template sketch. In order to further refine the obtained candidate image patches, a multi-feature-based optimization model is introduced. Finally, by assembling the refined candidate image patches, the completed face sketch is obtained. To further enhance the quality of synthesized sketches, a cascaded regression strategy is adopted. Compared with the state-of-the-art face sketch synthesis methods, experimental results on several commonly used face sketch databases and celebrity photos demonstrate the effectiveness of the proposed method.

    Karapanos, Evangelos; Hassenzahl, Marc

    2009-01-01

    This paper presents iScale, a survey tool that aims at eliciting users' experiences with a product from memory. iScale employs sketching in imposing a process in the reconstruction of one's experiences. Two versions of iScale, the Constructive and the Value-Account iScale, were motivated by two distinct theories on how people reconstruct emotional experiences from memory. These two versions were tested in two separate studies. Study 1 aimed at providing qualitative insight into the use of iScale and compared its performance to that of free-hand sketching. Study 2 compared the two iScale versions to a control condition: that of reporting one's experiences without employing any form of sketching. Significant differences between iScale and the "no-sketching" tool were found. Overall, iScale resulted in a) an increase in the number of experience reports that subjects provided, b) an increase in the amount of contextual information for the reported experiences, and c) an increase in subjects' accuracy in recalling...

  5. Sketch-n-Stretch: sketching animations using cutouts.

    Science.gov (United States)

    Sohn, Eisung; Choy, Yoon-Chul

    2012-01-01

    Sketch-n-Stretch lets novices quickly and easily create 2D animations. The system has a seamless two-layer drawing interface that supports cutouts using a whiteboard metaphor. Cutout animations serve as building blocks to help users construct sophisticated animations. While manipulating cutout animations, users can draw and write text to create effects-such as articulated figures, multiple motions, and image objects-that have been difficult with previous sketching approaches. An intuitive timeline interface employs visually integrated motion cues and supports several traditional animation effects. Novices positively evaluated Sketch-n-Stretch's effectiveness in creating object motions, compared to an existing sketching tool. They also used its advanced features to animate complete stories. This video demonstrates the Sketch-n-Stretch tool for making sketch-based animations. PMID:24806002

    Full Text Available Este artigo procura traçar o percurso profissional de Eliezer Schneider, um dos primeiros brasileiros com formação acadêmica em Psicologia. Formado em Direito em 1939, pela Faculdade Nacional de Direito da antiga Universidade do Brasil (hoje UFRJ, prestou concurso para o Instituto de Psicologia daquela universidade, onde ingressou em 1941. Poucos anos depois, obteve o título de Mestre em Psicologia pela Universidade de Iowa (EUA com tese sobre as teorias emergentistas da personalidade, orientada pelo professor Gustavo Bergman. Da experiência nessa Universidade permaneceu seu interesse pelo behaviorismo, menos talvez por sua metodologia do que por sua ênfase nas situações ambientais como determinantes do comportamento humano. Seu interesse pela Psicologia, segundo seu próprio relato, surgiu com o estudo do Direito - como entender o criminoso, como caracterizar a inimputabilidade? Sua principal influência, contudo, se encontra na formação de toda uma geração de professores de Psicologia Social que, com ele, aprendemos a estender nosso olhar além do paradigma individualista e intimista que caracteriza nossa Psicologia.This article presents the professional trajectory of Eliezer Schneider, one of the first Brazilians with academic training in Psychology. Graduated in Law, in 1939, by National College of Law of the old University of Brazil (nowadays Federal University of Rio de Janeiro, he applied to a position at the Institute of Psychology of that University, being hired in 1941. Few years later, he got the Master degree by University of Iowa (USA, with a thesis about the emergentist theories of personality, under the supervision of Gustavo Bergman. Due to his experience at that University, Schneider kept his interest in behaviorism alive, perhaps not so for its methodology but for its emphasis in environmental situations as determinants of human behavior. His interest in Psychology, according to his own report, began with Law studies - how to understand the criminal, how to characterize his/her unliability? However, his main contribution relates to the training of a whole generation of Social Psychology teachers, who have learned, with him, to extend our sight beyond the paradigm of individualism and intimacy that identifies our Psychology.

    Science.gov (United States)

    May, Ulrike

    2010-01-01

    On the basis of mostly unpublished sources, the author reconstructs the life of the Hungarian writer Viktor von Dirsztay (1884?-1935) who was personally acquainted with many expressionist artists and writers, e. g. with Karl Kraus, Oskar Kokoschka, Herwarth Walden, Walter Hasenclever, Hermann Broch and Arthur Schnitzler. This association puts Freud into closer proximity with the cultural avantgarde of his times than previously realized. Between 1910 and 1920 Dirsztay underwent several phases of analysis with Freud; then he was treated by Theodor Reik. The overall length of his analysis with Freud is almost unparalleled. The article discusses whether and in which way Dirsztay's writings might have been influenced by his analyses and how Freud and Reik might have drawn upon their experiences with this patient. It is argued that likely references can be discovered in both authors' theories of masochism. There is an intriguing late remark of Dirsztay's that he was "ruined by analysis".

  12. Warburg effect(s)-a biographical sketch of Otto Warburg and his impacts on tumor metabolism.

    Otto, Angela M

    2016-01-01

    Virtually everyone working in cancer research is familiar with the "Warburg effect", i.e., anaerobic glycolysis in the presence of oxygen in tumor cells. However, few people nowadays are aware of what lead Otto Warburg to the discovery of this observation and how his other scientific contributions are seminal to our present knowledge of metabolic and energetic processes in cells. Since science is a human endeavor, and a scientist is imbedded in a network of social and academic contacts, it is worth taking a glimpse into the biography of Otto Warburg to illustrate some of these influences and the historical landmarks in his life. His creative and innovative thinking and his experimental virtuosity set the framework for his scientific achievements, which were pioneering not only for cancer research. Here, I shall allude to the prestigious family background in imperial Germany; his relationships to Einstein, Meyerhof, Krebs, and other Nobel and notable scientists; his innovative technical developments and their applications in the advancement of biomedical sciences, including the manometer, tissue slicing, and cell cultivation. The latter were experimental prerequisites for the first metabolic measurements with tumor cells in the 1920s. In the 1930s-1940s, he improved spectrophotometry for chemical analysis and developed the optical tests for measuring activities of glycolytic enzymes. Warburg's reputation brought him invitations to the USA and contacts with the Rockefeller Foundation; he received the Nobel Prize in 1931. World politics and world wars heavily affected Warburg's scientific survival in Berlin. But, after his second postwar recovery, Warburg's drive for unraveling the energetic processes of life, both in plants and in tumor cells, continued until his death in 1970. The legacy of Otto Warburg is not only the Warburg effect, but also the identification of the "respiratory ferment" and hydrogen-transferring cofactors and the isolation of glycolytic enzymes. His hypothesis of respiratory damage being the cause of cancer remains to be a provocative scientific issue, along with its implications for cancer treatment and prevention. Warburg is therefore still stimulating our thinking, as documented in a soaring increase in publications citing his name in the context of tumor metabolism.

    Computer aided design is vitally important for the modern industry, particularly for the creative industry. Fashion industry faced intensive challenges to shorten the product development process. In this paper, a methodology is proposed for sketch design based on interactive genetic algorithms. The sketch design system consists of a sketch design model, a database and a multi-stage sketch design engine. First, a sketch design model is developed based on the knowledge of fashion design to describe fashion product characteristics by using parameters. Second, a database is built based on the proposed sketch design model to define general style elements. Third, a multi-stage sketch design engine is used to construct the design. Moreover, an interactive genetic algorithm (IGA) is used to accelerate the sketch design process. The experimental results have demonstrated that the proposed method is effective in helping laypersons achieve satisfied fashion design sketches.

    Full Text Available In this paper, we present results of an evaluation of Japanese word sketches and address in detail issues that were observed by the evaluators. A word sketch presents a list of salient collocates of a word, organized by the grammatical relations holding between the word and its collocate. The word sketch functionality is incorporated into the Sketch Engine corpus query system and has been created for more than twenty languages so far, including Japanese. The issues that have been discovered in the evaluation of word sketches in Japanese are to be addressed for further enhancement of the word sketch functionality. Other tools and resources which are combined for use and influence the performance of the word sketches should also be looked over. We divide the issues into the following: 1 the lemmatizer and tagger in use, 2 the sketch grammar that is specifically written for Japanese, and 3 the corpus and statistical methods.

    This paper presents a novel facial sketch image or face-sketch recognition approach based on facial feature extraction. To recognize a face-sketch, we have concentrated on a set of geometric face features like eyes, nose, eyebrows, lips, etc and their length and width ratio because it is difficult to match photos and sketches because they belong to two different modalities. In this system, first the facial features/components from training images are extracted, then ratios of length, width, a...

    Full Text Available This paper is a summary of some phonological and morphosyntactice features of the Bhadarwahi language of Indo-Aryan family. Bhadarwahi is a lesser known and less documented language spoken in district of Doda of Jammu region of Jammu and Kashmir State in India. Typologically it is a subject dominant language with an SOV word order (SV if without object and its verb agrees with a noun phrase which is not followed by an overt post-position. These noun phrases can move freely in the sentence without changing the meaning of the sentence. The indirect object generally precedes the direct object. Aspiration, like any other Indo-Aryan languages, is a prominent feature of Bhadarwahi. Nasalization is a distinctive feature, and vowel and consonant contrasts are commonly observed. Infinitive and participle forms are formed by suffixation while infixation is also found in causative formation. Tense is carried by auxiliary and aspect and mood is marked by the main verb.

    Two-dimensional (2D) maps and cross-sections, and 3D conceptual models, are fundamental tools for understanding, communicating and modeling geology. Yet geologists lack dedicated and intuitive tools that allow rapid creation of such figures and models. Standard drawing packages produce only 2D figures that are not suitable for quantitative analysis. Geologic modeling packages can produce 3D models and are widely used in the groundwater and petroleum communities, but are often slow and non-intuitive to use, requiring the creation of a grid early in the modeling workflow and the use of geostatistical methods to populate the grid blocks with geologic information. We present an alternative approach to rapidly create figures and models using sketch-based interface and modelling (SBIM). We leverage methods widely adopted in other industries to prototype complex geometries and designs. The SBIM tool contains built-in geologic rules that constrain how sketched lines and surfaces interact. These rules are based on the logic of superposition and cross-cutting relationships that follow from rock-forming processes, including deposition, deformation, intrusion and modification by diagenesis or metamorphism. The approach allows rapid creation of multiple, geologically realistic, figures and models in 2D and 3D using a simple, intuitive interface. The user can sketch in plan- or cross-section view. Geologic rules are used to extrapolate sketched lines in real time to create 3D surfaces. Quantitative analysis can be carried our directly on the models. Alternatively, they can be output as simple figures or imported directly into other modeling tools. The software runs on a tablet PC and can be used in a variety of settings including the office, classroom and field. The speed and ease of use of SBIM enables multiple interpretations to be developed from limited data, uncertainty to be readily appraised, and figures and models to be rapidly updated to incorporate new data or concepts.

    Capturing the nature of students' mental representations and how they change with learning is a primary goal in science education research. This can be challenging in spatially intense domains, such as geoscience, architecture, and engineering. In this research, we test whether sketching can be used to gauge level of expertise in geoscience, using new technology designed to facilitate this process. We asked participants with differing levels of geoscience experience to copy two kinds of geoscience images—photographs of rock formations and causal diagrams. To permit studying the process of sketching as well as the structure and content of the sketches, we used the CogSketch system (Forbus et al. 2011, Topics in Cognitive Science 3:648-666) to record the time course of sketching and analyze the sketches themselves. Relative to novices, geoscience students included more geological structures and relational symbols in their sketches of geoscience materials and were more likely to construct their sketches in a sequence consistent with the order of causal events. These differences appear to stem from differences in domain knowledge, because they did not show up in participants' sketches of materials from other fields. The findings and methods of this research suggest new ways to promote and assess science learning, which are well suited to the visual-spatial demands of many domains.

    In real life scenario, we may be interested in face recognition for identification purpose when we only got sketch of the face images, for example, when police tries to identify criminals based on sketches of suspect, which is drawn by artists according to description of witnesses, what they have in hand is a sketch of suspects, and many real face image acquired from video surveillance. So far the state-of-the-art approach toward this problem tries to transform all real face images into sketches and perform recognition on sketch domain. In our approach we propose the opposite which is a better approach; we propose to generate a realistic face image from the composite sketch using a Hybrid subspace method and then build an illumination tolerant correlation filter which can recognize the person under different illumination variations. We show experimental results on our approach on the CMU PIE (Pose Illumination and Expression) database on the effectiveness of our novel approach.

    The field of sketch-based interfaces and modeling (SBIM) is concerned with developing methods and techniques to enable users to interact with a computer through sketching - a simple, yet highly expressive medium. SBIM blends concepts from computer graphics, human-computer interaction, artificial intelligence, and machine learning. Recent improvements in hardware, coupled with new machine learning techniques for more accurate recognition, and more robust depth inferencing techniques for sketch-based modeling, have resulted in an explosion of both sketch-based interfaces and pen-based computing

    Sketching is a valuable field technique to support a person's observation, recording, interpretation and communication of important features in both natural and human-made landscapes. The Singapore geography syllabus employs an inquiry approach and encourages sketching as a fundamental geographical skill. Sketching allows the learner to connect with the world through a personal and kinesthetic experience. The Earth Observatory of Singapore collaborates with the Singapore Geography Teachers' Association, Urban Sketchers, and National Institute of Education professional development to give teachers both basic sketching skills and the opportunity to develop those skills in a scaffolded environment. In Singapore, geography and geology skills overlap in content area of coastal processes, climate change, and plate tectonics with its associated natural hazards such as volcanoes, earthquakes, and tsunami. Both disciplines are interested in how people live on the Earth. Likewise, basic skills such as observing, classifying, measuring, and communicating cut across disciplines of social and natural sciences in order to analyze, synthesize, and evaluate information about the world. Hence, sketching, commonly considered an art skill, is used to further scientific thinking. This somewhat unique collaboration to develop sketching in teachers is based on the long tradition of sketches in geological field work, the newly popular urban sketching community, and professional development by a professional organization and the Singapore National Institute of Education. Workshops provide technique as well as opportunities for sketching with experts in different areas relevant to the geography curriculum.

    Soon after you begin studying the sky through your small telescope or binoculars, you will probably be encouraged by others to make sketches of what you see. Sketching is a time-honored tradition in amateur astronomy and dates back to the earliest times, when telescopes were invented. Even though we have lots of new imaging technologies nowadays, including astrophotography, most observers still use sketching to keep a record of what they see, make them better observers, and in hopes of perhaps contributing something to the body of scientific knowledge about the Moon. Some even sketch because it satisfies their artistic side. The Moon presents some unique challenges to the astronomer-artist, the Moon being so fond of tricks of the light. Sketching the Moon: An Astronomical Artist’s Guide, by five of the best lunar observer-artists working today, will guide you along your way and help you to achieve really high-quality sketches. All the major types of lunar features are covered, with a variety of sketching te...

  9. Recursive Sketching For Frequency Moments

    In a ground-breaking paper, Indyk and Woodruff (STOC 05) showed how to compute $F_k$ (for $k>2$) in space complexity $O(\\mbox{\\em poly-log}(n,m)\\cdot n^{1-\\frac2k})$, which is optimal up to (large) poly-logarithmic factors in $n$ and $m$, where $m$ is the length of the stream and $n$ is the upper bound on the number of distinct elements in a stream. The best known lower bound for large moments is $\\Omega(\\log(n)n^{1-\\frac2k})$. A follow-up work of Bhuvanagiri, Ganguly, Kesh and Saha (SODA 2006) reduced the poly-logarithmic factors of Indyk and Woodruff to $O(\\log^2(m)\\cdot (\\log n+ \\log m)\\cdot n^{1-{2\\over k}})$. Further reduction of poly-log factors has been an elusive goal since 2006, when Indyk and Woodruff method seemed to hit a natural "barrier." Using our simple recursive sketch, we provide a different yet simple approach to obtain a $O(\\log(m)\\log(nm)\\cdot (\\log\\log n)^4\\cdot n^{1-{2\\over k}})$ algorithm for constant $\\epsilon$ (our bound is, in fact, somewhat stronger, where the $(\\log\\log n)$ term c...

  11. Sketch Matching on Topology Product Graph.

    2015-08-01

    Sketch matching is the fundamental problem in sketch based interfaces. After years of study, it remains challenging when there exists large irregularity and variations in the hand drawn sketch shapes. While most existing works exploit topology relations and graph representations for this problem, they are usually limited by the coarse topology exploration and heuristic (thus suboptimal) similarity metrics between graphs. We present a new sketch matching method with two novel contributions. We introduce a comprehensive definition of topology relations, which results in a rich and informative graph representation of sketches. For graph matching, we propose topology product graph that retains the full correspondence for matching two graphs. Based on it, we derive an intuitive sketch similarity metric whose exact solution is easy to compute. In addition, the graph representation and new metric naturally support partial matching, an important practical problem that received less attention in the literature. Extensive experimental results on a real challenging dataset and the superior performance of our method show that it outperforms the state-of-the-art.

    Cai Yuanpei wrote a great many biographical writings in his life though he wasn' t famous for writing biography. In the period of his formative education and studying freely, he accumulated the attainment of biographical writing and cultivated gradually the sense of cultural identification based on Chinese ancient bi- ography. When embarking on political revolution and educational innovation, he became more active in bio- graphical writing, especially choosing those revolutionaries, relatives and friends as leading characters. In his later years, he wrote autobiography with a style of annals suggested by Hu Shi. All in all, it was very obvious that Cai should be a helpful promotion to modem transformation of Chinese biographical idea though he wasn' t determined biographical writer and researcher, including his lack of more profound biographical theories and very self-conscious sense of modem biographical style.%蔡元培并不是一位以写作传记而闻名的文学家,但在一生中写下了大量的传记作品。在接受启蒙教育和“自由”读书的过程中,他积累了良好的传记写作素养,逐渐形成了对中国传记文化的认同感。随着政治革命、教育革新等活动的展开,他更是积极写作各种人物传记,其中的革命家传和亲友传最具特色。晚年在胡适的影响下用年谱体写作自传。尽管蔡元培的志向并不在传记写作及研究上,此外亦无十分深刻的传记理论见解和非常自觉的现代传记文体意识,但对中国传记文学观念的现代转型具有一定的助推作用。

    Presenting and communicating insights to an audience-telling a story-is one of the main goals of data exploration. Even though visualization as a storytelling medium has recently begun to gain attention, storytelling is still underexplored in information visualization and little research has been done to help people tell their stories with data. To create a new, more engaging form of storytelling with data, we leverage and extend the narrative storytelling attributes of whiteboard animation with pen and touch interactions. We present SketchStory, a data-enabled digital whiteboard that facilitates the creation of personalized and expressive data charts quickly and easily. SketchStory recognizes a small set of sketch gestures for chart invocation, and automatically completes charts by synthesizing the visuals from the presenter-provided example icon and binding them to the underlying data. Furthermore, SketchStory allows the presenter to move and resize the completed data charts with touch, and filter the underlying data to facilitate interactive exploration. We conducted a controlled experiment for both audiences and presenters to compare SketchStory with a traditional presentation system, Microsoft PowerPoint. Results show that the audience is more engaged by presentations done with SketchStory than PowerPoint. Eighteen out of 24 audience participants preferred SketchStory to PowerPoint. Four out of five presenter participants also favored SketchStory despite the extra effort required for presentation.

    1985-01-01

    A biographical conception of neurosis requires a dynamical perspective of personality which may be defined as the relative stability of a person in time. The life-cycle is not merely a sequence of data but a complex pattern which can be reconstructed by all semiotic systems. But the ordinary all-purpose language is to be preferred because of its flexibility to fit even very complicated state of affairs. The narration of a life-cycle does not end in a unique version but a multiplicity of legitimate narratives. The unity of all these versions is conceived as paradigma, that means a set of similar examples. The extensional set of the paradigma shows a kind of order which may be characterized intensionally by a rule or a sense. The seeming irrationality of a neurotic symptom is caused by its belonging to a different paradigma for which there is a sense. Psychotherapy is an attempt to give the seeming irrational symptoms a specific sense and to change it in a second step. PMID:3834702

    Debris-flow frequency, discharge, and travel distance are highly catchment dependent and typically controlled by topography, hydrological conditions, and sediment supply. As a consequence, detailed and case-specific investigations are needed to decipher debris-flow histories in order to improve hazard mitigation. This study documents past (ca. 10 years) debris-flow occurrences originating from the Ohya landslide, central Japan, by using a large set of methods including field monitoring, repeat airborne LiDAR, orthophoto interpretation, and tree-ring reconstructions. We demonstrate that the different approaches generally agree on the occurrence of debris flows but that mismatches may exist when it comes to the assessment of areas affected by individual events. These differences may even exceed the usual errors in precision inherent to each of the methods used. In the present case, high-resolution orthophoto interpretation tends to underestimate areas affected by debris flows, especially in the vertical direction, in the absence of lateral movement of the channel bed and as a result of shade and areas under trees. On the other hand, we realize that LiDAR data cannot necessarily be used to distinguish local changes in topography from noise. Tree-ring analyses can help to improve the temporal resolution of the analysis, but may have limitations when it comes to the definition of areas affected by an event because of the point-type nature of data. We conclude that the best and most complete results are obtained by combining multiple methods to improve the spatial and temporal resolution of past debris flows and to delimit areas affected by individual events.

    Sketching and streaming algorithms are in the forefront of current research directions for cut problems in graphs. In the streaming model, we show that $(1-\\epsilon)$-approximation for Max-Cut must use $n^{1-O(\\epsilon)}$ space; moreover, beating $4/5$-approximation requires polynomial space. For the sketching model, we show that $r$-uniform hypergraphs admit a $(1+\\epsilon)$-cut-sparsifier (i.e., a weighted subhypergraph that approximately preserves all the cuts) with $O(\\epsilon^{-2} n (r+\\...

    2008-01-01

    We present the basic ideas of forms (a generalization of Ehresmann's sketches) and their theories and models, more explicitly than in previous expositions. Forms provide the ability to specify mathematical structures and data types in any appropriate category, including many types of structures (e.g. function spaces) that cannot be specified by sketches. We also outline a new kind of formal logic (based on graphs instead of strings of symbols) that gives an intrinsically categorial definition of assertion and proof for each type of form. This formal logic is new to this monograph. The relationship between multisorted equational logic and finite product theories is worked out in detail.

  19. Ḥanafī Biographical Dictionaries: A Survey

    Ermin Sinanovic

    2001-06-01

    Full Text Available This paper deals with biographical dictionaries-one of the main genres in Muslim historiography. The first part involves some theoretical considerations related to biographical dictionaries. This includes definition and classification of this type of literature. In addition, this paper dismisses the claim forwarded by some Orientalists that this genre was initiated by Traditionalists so that they could pass themselves off as 'genuine' scholars to the exclusion of all others. While the Orientalists' claim may have some weight, this study contends that biographical dictionaries have been primarily motivated by the Islamic conception of historiography, i.e. the preservation of the memory of previous scholars so that later Muslim generations could emulate their deeds. The second part surveys five Ḥanafī biographical dictionaries within the framework of the questions of motive, method, selectivity, and the issue of factual information and subjective evaluation. The survey confirms the hypothesis that the composition of biographical dictionaries was genuinely inspired by religious considerations. The paper also examines the linkage among these different dictionaries, and derives several important conclusions there from. Lastly, the paper analyzes the content of the surveyed dictionaries and relates it to the theoretical considerations discussed in the first part.

    2016-02-01

    Full Text Available The continuous development of biometric technology has provided criminal investigators additional gadgets to discover the identity of criminals. In addition to DNA and incidental proofs, if a hidden fingerprint is found at an investigative sight or a surveillance camera captures an image or an footage of a suspect’s face, then these clues may be used to discover the culprit’s identity using automated biometric identification. However, many crimes occur where there is above information isn’t present, but instead an eyewitness of the crime is present. In these situations a forensic artist is often used to work with the witness or the victim in order to draw blueprints that depicts the facial features of the culprit according to the verbal illustrations. These blueprints are known as forensic sketches. This problem of comparing a forensic sketch to a gallery of headshots images is addressed here using a robust framework called local feature-based discriminant analysis (LFDA.

    Full Text Available Illustrated Sketches of Death Valley (1891 originated as a hastily-written series of journalistic sketches of our Western borax deserts. They were written on commission to supplement their authors income. Conceived as a means subtly to promote the borax industry the Sketches in time won unintended recognition as a classic source for their subject. They also assumed unforeseen importance as an illustration of the role of advertising in America’s changing economy.

    Zhan DING; Shu-chang XU; Xiu-zi YE; Yin ZHANG; San-yuan ZHANG

    2008-01-01

    In this paper we propose a method to model flowers of solid shape. Based on (Ijiri et al., 2005)'s method, we separate individual flower modeling and inflorescence modeling procedures into structure and geometry modeling. We incorporate interactive editing gestures to allow the user to edit structure parameters freely onto structure diagram. Furthermore, we use free-hand sketching techniques to allow users to create and edit 3D geometrical elements freely and easily. The final step is to automatically merge all independent 3D geometrical elements into a single waterproof mesh. Our experiments show that this solid modeling approach is promising. Using our approach, novice users can create vivid flower models easily and freely. The generated flower model is waterproof. It can have applications in visualization, animation, gaming, and toys and decorations if printed out on 3D rapid prototyping devices.

  20. Dressing and Hair-Styling Virtual Characters from a Sketch

    Science.gov (United States)

    Wither, Jamie; Cani, Marie-Paule

    This chapter presents a different use of sketch-based modeling, namely the modeling of complex objects from a single sketch, illustrated by the examples of dressing and hairstyling a virtual character. Knowing the nature of the object being modeled eases the extraction of information from a sketch, so that a single sketch depicting a front view (and optionally a second one from the back or side) is sufficient to specify these complex 3D shapes. We show how different levels of prior knowledge about the object being modeled, from basic rules of thumb to more intricate geometric or physically based properties, can be used to interpret the sketch strokes and to infer the missing 3D information, leading to different degrees of visual realism. In addition to discussing practical solutions for the sketch-based modeling of garments and hair that save several orders of magnitude of user time compared to standard 3D modeling methods, this chapter provides the basis of a general methodology towards the design of sketch-based interfaces for complex models.

  4. A Sketch Learning Support Environment that Gives Area-dependent Advice during Drawing the Sketch

    Science.gov (United States)

    Soga, Masato; Matsuda, Noriyuki; Taki, Hirokazu

    Skill, such as arts, sports and crafts, is regarded as a cycle that consists of the following three steps: recognition of objects, selection of appropriate action series and execution of the action. In arts and crafts, people produce works as a result of this cycle. Skill-learning environment should involve diagnosis-function providing appropriate advice for each step. This paper describes technique that is providing advice in real time when a learner learns recognition of drawing. To assist learners' recognition, we developed the sketch-area-dependent advising system that presents advice with voice for learners' drawing. The effectiveness of advice was confirmed through an experiment evaluating proposed technique.

  5. Mathematical Sketching: An Approach to Making Dynamic Illustrations

    Science.gov (United States)

    Laviola, Joseph J.

    Mathematical sketching is a pen-based, gestural interaction paradigm for mathematics problem solving. It derives from the familiar pencil-and-paper process of drawing supporting diagrams to facilitate the formulation of mathematical expressions; however, with mathematical sketching, users can also leverage their physical intuition by watching their hand-drawn diagrams animate in response to continuous or discrete parameter changes in their written formulas. Diagram animation is driven by implicit associations that are inferred, either automatically or with gestural guidance, from mathematical expressions, diagram labels, and drawing elements. In this chapter, we discuss the important issues related to the mathematical sketching paradigm such as the development of a fluid gestural user interface, recognition of mathematical expressions, and the preparation and translation of mathematical sketches into animated illustrations.

  7. Aircraft Conceptual Design Using Vehicle Sketch Pad

    Fredericks, William J.; Antcliff, Kevin R.; Costa, Guillermo; Deshpande, Nachiket; Moore, Mark D.; Miguel, Edric A. San; Snyder, Alison N.

    2010-01-01

    Vehicle Sketch Pad (VSP) is a parametric geometry modeling tool that is intended for use in the conceptual design of aircraft. The intent of this software is to rapidly model aircraft configurations without expending the expertise and time that is typically required for modeling with traditional Computer Aided Design (CAD) packages. VSP accomplishes this by using parametrically defined components, such as a wing that is defined by span, area, sweep, taper ratio, thickness to cord, and so on. During this phase of frequent design builds, changes to the model can be rapidly visualized along with the internal volumetric layout. Using this geometry-based approach, parameters such as wetted areas and cord lengths can be easily extracted for rapid external performance analyses, such as a parasite drag buildup. At the completion of the conceptual design phase, VSP can export its geometry to higher fidelity tools. This geometry tool was developed by NASA and is freely available to U.S. companies and universities. It has become integral to conceptual design in the Aeronautics Systems Analysis Branch (ASAB) here at NASA Langley Research Center and is currently being used at over 100 universities, aerospace companies, and other government agencies. This paper focuses on the use of VSP in recent NASA conceptual design studies to facilitate geometry-centered design methodology. Such a process is shown to promote greater levels of creativity, more rapid assessment of critical design issues, and improved ability to quickly interact with higher order analyses. A number of VSP vehicle model examples are compared to CAD-based conceptual design, from a designer perspective; comparisons are also made of the time and expertise required to build the geometry representations as well.

  10. Geoillustrator - fast sketching of geological illustrations and animations

    Science.gov (United States)

    Patel, Daniel; Langeland, Tor; Solteszova, Veronika

    2014-05-01

    We present our research results in the Geoillustrator project. The project has been going for four years and is ending in March. It was aimed at developing a rapid sketching tool for generating geological illustrations and animations for understanding the processes that have led to a current subsurface configuration. The sketching tool facilitates effective dissemination of ideas, e.g. through generation of interactive geo-scientific illustrations for interdisciplinary communication and communication to decision makers, media and lay persons. This can improve work processes in early phases of oil and gas exploration where critical decisions have to be taken based on limited information. It is a challenge for involved specialists in early exploration phases to externalize their ideas, and effectively achieve consensus in multidisciplinary working groups. In these work processes, a tool for rapid sketching of geology would be very useful for expressing geological hypotheses and creating and comparing different evolution scenarios. Often, decisions are influenced by factors that are not relevant, e.g. the geologists who produce the most polished illustrations of their hypothesis have a higher probability for getting their theories through to decision makers as it is more clearly communicated. This results in a competitive advantage for geologists who are skilled in creating illustrations. Having a tool that would lift the ability of all geologists to express their ideas to an equal level would result in more alternatives and better foundation for decision making. Digital sketching will also allow capturing otherwise lost material which can constitute a large amount of mental work and ideas. The results of sketching are currently scrapped as paper or erased from the blackboard or exist only as rough personal sketches. By using a digital sketching tool, the sketches can be exported to a form usable in modelling tools used in later phases of exploration. Currently, no

  11. gSketch: On Query Estimation in Graph Streams

    CERN Document Server

    Zhao, Peixiang; Wang, Min

    2011-01-01

    Many dynamic applications are built upon large network infrastructures, such as social networks, communication networks, biological networks and the Web. Such applications create data that can be naturally modeled as graph streams, in which edges of the underlying graph are received and updated sequentially in a form of a stream. It is often necessary and important to summarize the behavior of graph streams in order to enable effective query processing. However, the sheer size and dynamic nature of graph streams present an enormous challenge to existing graph management techniques. In this paper, we propose a new graph sketch method, gSketch, which combines well studied synopses for traditional data streams with a sketch partitioning technique, to estimate and optimize the responses to basic queries on graph streams. We consider two different scenarios for query estimation: (1) A graph stream sample is available; (2) Both a graph stream sample and a query workload sample are available. Algorithms for differen...

  13. Auditory Sketches: Very Sparse Representations of Sounds Are Still Recognizable.

    Directory of Open Access Journals (Sweden)

    Vincent Isnard

    Full Text Available Sounds in our environment like voices, animal calls or musical instruments are easily recognized by human listeners. Understanding the key features underlying this robust sound recognition is an important question in auditory science. Here, we studied the recognition by human listeners of new classes of sounds: acoustic and auditory sketches, sounds that are severely impoverished but still recognizable. Starting from a time-frequency representation, a sketch is obtained by keeping only sparse elements of the original signal, here, by means of a simple peak-picking algorithm. Two time-frequency representations were compared: a biologically grounded one, the auditory spectrogram, which simulates peripheral auditory filtering, and a simple acoustic spectrogram, based on a Fourier transform. Three degrees of sparsity were also investigated. Listeners were asked to recognize the category to which a sketch sound belongs: singing voices, bird calls, musical instruments, and vehicle engine noises. Results showed that, with the exception of voice sounds, very sparse representations of sounds (10 features, or energy peaks, per second could be recognized above chance. No clear differences could be observed between the acoustic and the auditory sketches. For the voice sounds, however, a completely different pattern of results emerged, with at-chance or even below-chance recognition performances, suggesting that the important features of the voice, whatever they are, were removed by the sketch process. Overall, these perceptual results were well correlated with a model of auditory distances, based on spectro-temporal excitation patterns (STEPs. This study confirms the potential of these new classes of sounds, acoustic and auditory sketches, to study sound recognition.

  2. The Pasteurization of Marie Curie: A (meta)biographical experiment.

    2015-08-01

    Biographies of scientists occupy a liminal space, highly popular with general readers but questioned in academia. Nonetheless, in recent years, historians of science have not only embraced the genre with more enthusiasm and less guilt, they have also turned to the metabiography in order to renew the study and story of scientists' roles. This essay focuses on Marie Curie, the world's most famous female scientist, in order to unpack some of the theoretical and methodological claims of the science biography, and especially to address the sexing mechanisms at play in the construction of the biographical subject. Pierre Curie (1923), Marie's biography of her husband Pierre, paid tribute to her dead husband and collaborator, but also allowed Curie a legitimate outlet to construct her own persona and legacy. Categories such as personhood, person, and persona are not only central to the biography genre but also are essential to the sense of self and self-fashioning of scientists. Looking at how Marie Curie negotiated these categories in Pierre Curie not only gives new insight into Curie's self-fashioning strategies but may also shed some light on the more general analytical lacunae of the science biography.

  9. Ingmar Bergman, the biographical legend and the intermedialities of memory

    Directory of Open Access Journals (Sweden)

    Maaret Koskinen

    2010-12-01

    Full Text Available Ingmar Bergman (1918–2007 wrote his autobiography The Magic Lantern (Laterna magica, 1987 5 years after he had finished his film career with Fanny and Alexander, his last feature made for the cinema screen. This arguably marked the second stage of his strictly literary career, the first being his plays for the stage in the 1940s. The Magic Lantern is of interest from an intermedial perspective in its forthright theatricalization or cinematization of the written text and the self-conscious performativity of its authorial voice. Of particular interest is the way the narrator turns into a kind of distanciated autobiographical witness, which in turn reminds the reader of the inherent narrative split in the autobiographical genre between the enunciating subject speaking from the present, and the described subject, the younger self in the past. In doing so the narrator seems to turn language itself into a performative venue: the medium of words becomes a theatrical stage or a cinematically charged mise-en-scène for memory as such.This is of course not only stylistically elegant, for what can be more natural than a film- and theater director who, as the very title of the autobiography announces, turns memories into cinematic and theatrical performances? But even more interesting is the extent to which Bergman in doing so seems to conjur forth his biographical legend, reminding the reader of who is in charge of text: the narrator becomes the director of the text, so to speak, lighting and setting the stage.Besides this artful approach, Bergman also clearly fictionalized his life in other ways, which is corroborated by the private note books and original manuscripts that the writer of this paper has gained access to.

    2016-04-01

    Full Text Available The paper focuses on the stages in the development of mind in adults related to biographical self-reflection. The hypothesis of the study was that biographical self-reflection affects meaning-making, self-regulation and adaptation in the adults. The sample consisted of 480 individuals aged 25—65 years. The study measured indicators of biographical self-reflection, social psychological adaptation, life meaningfulness and self-regu- lation. We have found that in the age period of 46-65 years there is a shift from self-reflection on the path of life to self-reflection on life experience, which reinforces the influence of biographical self-reflection on the meaningfulness of life and self-regulation in the adults. Our study also revealed increases in biographical self-reflection at the beginning of age crises in adulthood (30—35, 40—45, 55—60 years when, as a result of reflective analysis, the adult realizes the need for change in his/her life.

  16. From Great Men to Ordinary Citizens? The Biographical Approach to Narrating European Integration in Museums

    Directory of Open Access Journals (Sweden)

    Wolfram Kaiserm

    2011-10-01

    Full Text Available The history of European integration is not easy to tell – in books or, for that matter, in museums. Most importantly, it appears to lack drama. This lack of drama creates a dilemma for museum practitioners who wish to tell stories about the contemporary history of Europe as shared history. In these circumstances, one prominent way of telling stories about European integration history in museums, and the focus of this article, is the biographical approach. Drawing upon research in all of the museums mentioned in this article and many more, and some 60 interviews with museum practitioners from across Europe, this article first discusses three biographical approaches to narrating European integration history in museums. It proceeds to draw out general conclusions about the prospects of mainstreaming European integration in history museums, and about the particular opportunities and pitfalls of the biographical approach and its different varieties.

  10. Multi-pen Sketch Recognition in a Learning Environment

    Directory of Open Access Journals (Sweden)

    Liam Don

    2009-04-01

    Full Text Available Virtual physics environments are becoming increasingly popular as a teaching tool for high school level mechanical physics. While useful, these tools often offer a complex user interface, lacking the intuitive nature of the traditional whiteboard. Furthermore, the systems are often too advanced to be used by novice students for further experimentation. In this paper we describe a physics learning environment using multicolour sketch recognition techniques on digital whiteboards. The recognition system is based on a combination of Support Vector Machines and rule based methods. By assigning the various drawing modes to different physical drawing pens, we can resolve several ambiguities appearing in single pen sketching interfaces. Moreover, we argue that we can reduce the cognitive load of the user by exploiting the physical realisation of drawing modes in the form of drawing pens, instead of using textual descriptions of the modes on the screen. The system was tested using a constructive interaction method, with users completing a set task; first in a multi-pen drawing environment, and then for comparison purposes in a singlepen equivalent.

  11. Human motion retrieval from hand-drawn sketch.

    Chao, Min-Wen; Lin, Chao-Hung; Assa, Jackie; Lee, Tong-Yee

    2012-05-01

    The rapid growth of motion capture data increases the importance of motion retrieval. The majority of the existing motion retrieval approaches are based on a labor-intensive step in which the user browses and selects a desired query motion clip from the large motion clip database. In this work, a novel sketching interface for defining the query is presented. This simple approach allows users to define the required motion by sketching several motion strokes over a drawn character, which requires less effort and extends the users’ expressiveness. To support the real-time interface, a specialized encoding of the motions and the hand-drawn query is required. Here, we introduce a novel hierarchical encoding scheme based on a set of orthonormal spherical harmonic (SH) basis functions, which provides a compact representation, and avoids the CPU/processing intensive stage of temporal alignment used by previous solutions. Experimental results show that the proposed approach can well retrieve the motions, and is capable of retrieve logically and numerically similar motions, which is superior to previous approaches. The user study shows that the proposed system can be a useful tool to input motion query if the users are familiar with it. Finally, an application of generating a 3D animation from a hand-drawn comics strip is demonstrated. PMID:21383410

    Burchardt, Marian

    2016-05-01

    This article analyses and theorises the practice of biographical storytelling of HIV-positive AIDS activists in South Africa. Combining research in illness narratives, studies of emotions in social activism and analysis of global health institutions in Africa, I explore how biographical self-narrations are deployed to facilitate access to resources and knowledge and thus acquire material and symbolic value. I illustrate my argument through the analysis of the case of an AIDS activist who became a professional biographical storyteller. Based on the analysis which I claim to represent wider dynamics in human-rights-based health activism in the Global South, I propose the concept of narrative economies by which I mean the set of exchange relationships within which biographical self-narrations circulate and produce social value for individuals and organisations.

    Zhang, Yunsong; Camley, Brian; Rappel, Wouter-Jan; Levine, Herbert

    Cell migration plays an important role in a lot of biological processes, like chemotaxis, wound healing, and cancer metastasis. The fact it is highly integrated has brought great challenges, physical and mathematical, to the modeling efforts. Recently, a phase field model, which couples cellular reaction dynamics, intra-cellular hydrodynamics, cell-substrate adhesions and deformable cell boundaries, has successfully captured some characteristics of moving cells, including morphological change, cytosolic actin flow pattern, periodic migration and so on. Here we apply the phase field model to sketch the migration of Dictyostelium discoideum, which shows a completely different moving pattern from the cells (like fish keratocyte) in our previous attempts. And we will also compare our results with some experimental observations, not only on the cell morphology, but also on the traction force patterns on the substrate.

  19. A theoretical sketch of medical professionalism as a normative complex.

    Science.gov (United States)

    Holtman, Matthew C

    2008-05-01

    Validity arguments for assessment tools intended to measure medical professionalism suffer for lack of a clear theoretical statement of what professionalism is and how it should behave. Drawing on several decades of field research addressing deviance and informal social control among physicians, a theoretical sketch of professionalism is presented that can be used to predict how individual adjustment to professional norms should co-vary with other social and psychological phenomena. Physicians may understand and value professional norms but fail to enact them in practice because of conflicting normative demands. Physicians' social networks are predicted to act as conduits of social learning and social pressure, driving the resolution of normative conflicts in specific directions. A valid assessment of professionalism requires an adequate accounting of the social reaction to an individual's professional conduct, because the reaction and the conduct itself are inseparable.

    We report a unique lithographic process, termed "Sketch and Peel" lithography (SPL), for fast, clean, and reliable patterning of metallic structures from tens of nanometers to submillimeter scale using direct writing technology. The key idea of SPL process is to define structures using their presketched outlines as the templates for subsequent selective peeling of evaporated metallic layer. With reduced exposure area, SPL process enables significantly improved patterning efficiency up to hundreds of times higher and greatly mitigated proximity effect compared to current direct writing strategy. We demonstrate that multiscale hierarchical metallic structures with arbitrary shapes and minimal feature size of ∼15 nm could be defined with high fidelity using SPL process for potential nanoelectronic and nano-optical applications.

    Stephen Leacock(1869-1944) is one of the founding parents of Canadian letters and literature. In the early 20th centu-ry, his reputation as a humorist and a political economist was not limited by the boundaries of Canada but spread around the world. As one of his works, Sunshine Sketches of a Little Town has attracted world-wide admiration. It is a series of vignettes dra-matizing the comedy of day-to-day life in Mariposa. It is bathed in the warm sunshine for all of us to laugh at as one of us re-members the little towns we might have known or come from. As a matter of fact, Leacock employs several techniques in his writing for humorous effect. This paper elaborates on the auther and the work, and makes an analysis on the character-Smith.

    People's lived experiences of chronic illness have garnered increasing research interest over the last 30-40 years, with studies recognising the disruptive influence of illness onset and progression, both to people's everyday lives and to their biographical selves. We extend this body of work, drawing on the experiences of people living with Ménière's disease; a long-term progressive vestibular disorder characterised by unpredictable episodes of debilitating vertigo, tinnitus and permanent sensorineural hearing loss. In response to calls for more critical examination of the wider biographical contexts in which chronic illnesses are encountered, we draw on 28 in-depth narrative interviews with Ménière's patients and their family members to discuss how personal chronic illness experiences may be closely entwined with, and deeply shaped by, the life transitions (illness-related and otherwise) of 'linked others'. Interviews were conducted in south west England from January to June 2015. Focusing on intersecting transitions of parenthood, caregiving and retirement, we explore how and why familial relationships can both facilitate and hinder adaptation to a lifetime of chronically disrupted normalities, contributing to fluctuating experiences of 'cherished time', 'anomalous time' and 'turbulent time'. In so doing, we suggest that the onset and progression of chronic illness could usefully be re-conceptualised as one of many 'biographical oscillations' encountered during the life course that serve to re-route us between continually shifting life trajectories. In recognising life's dynamism and challenging the identity-limiting and self-damaging nature of entrenched cultural life course constructions, we suggest value in recognising alternative ways of 'living well' when negotiating the wide-ranging biographical maps that life can follow.

    Full Text Available Article is devoted to poetics of biographical and memorialistic genres of XX century, especially to the analysis of such forms of laughter as irony and parody. The basic idea is concerned with fiction of the authors, which seek to destroy Genesis and alter reality, which in no way satisfied with the artists.The purpose of the article is identifying of the specifics of literary and imaginative reconstruction of historical events in the novels of M. Kuzmin and Sasha Sokolov by analyzing specifications of its narration.Method or the methodology of work: Among research material are M. Kuzmin’s novel "A wonderful life of Joseph Balsamo, count Cagliostro" and Sasha Sololov’s novel "Palisandria". Analyzing the texts of works on the researched topic were used comparative-historical, historical-biographical and structural methods.Results: Our study suggests that irony and parody in biographical and memorialistic genres of XX century have integrated, multifunctional meaning. Analysis of the novels allows us to observe the transformation of traditional biographical memorialistic narration into the grotesque model of the reality. There are interesting observations of the functioning in the works such approaches as parody, travesty, illogic, allegory, etc. As a result of the use of similar artistic techniques the novels become metatext about human nature in generalPractical implications: The results of our research can be used for lectures on the history of Russian literature of XXth century, in the course "History of Russian Literature" at faculties and departments of Russian Philology institutes and universities.

  8. SmartCanvas: Context-inferred Interpretation of Sketches for Preparatory Design Studies

    KAUST Repository

    Zheng, Youyi

    2016-05-27

    In early or preparatory design stages, an architect or designer sketches out rough ideas, not only about the object or structure being considered, but its relation to its spatial context. This is an iterative process, where the sketches are not only the primary means for testing and refining ideas, but also for communicating among a design team and to clients. Hence, sketching is the preferred media for artists and designers during the early stages of design, albeit with a major drawback: sketches are 2D and effects such as view perturbations or object movement are not supported, thereby inhibiting the design process. We present an interactive system that allows for the creation of a 3D abstraction of a designed space, built primarily by sketching in 2D within the context of an anchoring design or photograph. The system is progressive in the sense that the interpretations are refined as the user continues sketching. As a key technical enabler, we reformulate the sketch interpretation process as a selection optimization from a set of context-generated canvas planes in order to retrieve a regular arrangement of planes. We demonstrate our system (available at http:/geometry.cs.ucl.ac.uk/projects/2016/smartcanvas/) with a wide range of sketches and design studies. © 2016 The Author(s) Computer Graphics Forum © 2016 The Eurographics Association and John Wiley & Sons Ltd.

  10. Patients' narratives of chronic illnesses and the notion of biographical disruption.

    Science.gov (United States)

    Delbene, Roxana

    2011-01-01

    Bury's (1982) argument that the onset of a chronic illness represents a biographical disruption has become paradigmatic in the sociology of illness studies. More recently Bury (1991, 1997) himself Williams (2000) and other medical sociologists have argued that the notion of illness as biographical disruption needs re-examination. Following a phenomenological approach, in this paper the author draws on different narrative models (Labov and Waletzky 1967 and Ricoeur 1980) to analyze how patients orient to the onset of chronic illness as the complicating action. The data comprise eight narratives collected in South America: three correspond to patients with renal failure, and five to patients with HIV/AIDS disease. It is observed that in some cases, patients' complicating actions are rather oriented to experiences of poverty, drug addiction, and criminality that took place prior to their onset of their illnesses. These experiences, instead of the onset of their illnesses, occupy the place of the complicating action in these patients' narratives. The author discusses that in the studies of illness narratives, it is difficult to operate from a different paradigm, but argues that conflating the onset of chronic illness with a biographical disruption may confuse the episodic dimension of narrative with the configurational dimension.

    Full Text Available Reinterpretation is one of the activities that occur in visualization the role of reinterpretation is restructuring half form idea and it can be performed with applying sketch as a useful tool and creation development evaluation communication and sharing of ideas can be facilitated by sketching. Reinterpretation basically is the outcome of the lateral thinking process. Investigating of the reinterpretation of some designers indicate that externalizing a design may not be the solitary approach of designing visually and for expert architects sketching is not a crucial action in the early stages of conceptual designing. Moreover experts could progress in design by thinking only. However novice students have problem in reinterpreting patterns in their mental image whether tools such as sketch could help in the better performance of the reinterpretation process. This paper raises a fundamental question that if the sketch of novice students can support their mental imagery in order to answer this question this paper uses documentary method to investigate the previous studies in this field. Finally in accordance to the weakness of novices sketches this study concluded that their sketches could not support their mental imagery.

  12. Generation and use of sketches for chest X-ray image data base

    International Nuclear Information System (INIS)

    As the use of image processing technique extends into various fields, the realization of am image data base has been desired, which accumulates and manages images in large volume and takes the efficient retrieval and further the operative ability for processing into account. In this paper, the use of a kind of compressed images called ''sketch'' is proposed to do high grade retrieval based on image contents at high speed, and its usefulness is shown with the data base of actual chest X-ray images. The sketch must well express the main features of chest X-ray images (heart, ribs, blood vessels, forcuses, etc.) and minimize the quantity of data. The application of the developed sketch automatic extraction procedure to about 400 actual examples in the data base resulted in almost satisfactory extracted results. As an application of sketches, the retrieval using image pattern recognition technique and diagnostic results were recorded. In the experiment of extracting the cases of cardiomegaly out of 226 image sheets using the cardiothoracic ratio measured from the sketches, 11 sheets out of 14 true symptom cases were correctly retrieved to prove the usefulness of sketches to some extent. This data base of chest X-ray images is composed of an image input assembly which converts the directly and indirectly photographed images into digital density images of 3000 x 300 points, 8 bits per each point, and of five files, or master, control, header, temporary and sketch files.

    Full Text Available The issues associated with visualization images of the examined object and the method of sketches or visual notes have been discussed in the article. The images of lagenaria (bottle, shape pumpkins or gourds in works of art and agrobotanic illustration as a research tool have been selected, with the aim to conduct a visual analysis of the morphological characteristics of bottle gourd for further application of the knowledge gained in archaeogenetics and plant breeding. The article presents images of plants of lagenaria for the period from 1311 to 2014 years. Visual analysis of the morphological characteristics of lagenaria on the basis of visual notes allowed us to identify several key points: the polymorphism of fruits and different duration of the vegetation period, particularly of the reproductive system, which is characterized by different proportions of male and female flowers, the presence of pollinators, night flowering, fruit pubescence on the first stages of development, polymorphism seeds, features maturation based on the size and weight of the fetus. Understanding the range of individual development allows the breeder to submit a complete selection issue, search for new signs will touch the ancient forms of the object, diseases, pests, images which have remained only on the pictures. In our opinion, the method of visual notes can be successfully used in the educational process because it stimulates creativity and cognitive activity of students to search for information about the studied object and its reflection

    In order to learn effectively from measurements of generalised parton distributions (GPDs), it is desirable to compute them using a framework that can potentially connect empirical information with basic features of the Standard Model. We sketch an approach to such computations, based upon a rainbow-ladder (RL) truncation of QCD's Dyson-Schwinger equations and exemplified via the pion's valence dressed-quark GPD, $H_\\pi^{\\rm v}(x,\\xi,t)$. Our analysis focuses primarily on $\\xi=0$, although we also capitalise on the symmetry-preserving nature of the RL truncation by connecting $H_\\pi^{\\rm v}(x,\\xi=\\pm 1,t)$ with the pion's valence-quark parton distribution amplitude. We explain that the impulse-approximation used hitherto to define the pion's valence dressed-quark GPD is generally invalid owing to omission of contributions from the gluons which bind dressed-quarks into the pion. A simple correction enables us to identify a practicable improvement to the approximation for $H_\\pi^{\\rm v}(x,0,t)$, expressed as th...

    CERN Document Server

    Schrödinger, Erwin

    1992-01-01

    Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the twentieth century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman, but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. The philosopher Karl Popper hailed it as a 'beautiful and important book' by 'a great man to whom I owe a personal debt for many exciting discussions'. It appears here together with Mind and Matter, his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times. Schrodinger asks what place consciousness occupies in the evolution of life, and what part the state of development of the human mind plays in moral questions. Brought together with these two classics are Schrödinger's autobiographical sketches, published and translated here for the first time. They offer a fascinating fragmentary account of his life as a backgro...

  18. Facial Sketch Synthesis Using 2D Direct Combined Model-Based Face-Specific Markov Network.

    A facial sketch synthesis system is proposed, featuring a 2D direct combined model (2DDCM)-based face-specific Markov network. In contrast to the existing facial sketch synthesis systems, the proposed scheme aims to synthesize sketches, which reproduce the unique drawing style of a particular artist, where this drawing style is learned from a data set consisting of a large number of image/sketch pairwise training samples. The synthesis system comprises three modules, namely, a global module, a local module, and an enhancement module. The global module applies a 2DDCM approach to synthesize the global facial geometry and texture of the input image. The detailed texture is then added to the synthesized sketch in a local patch-based manner using a parametric 2DDCM model and a non-parametric Markov random field (MRF) network. Notably, the MRF approach gives the synthesized results an appearance more consistent with the drawing style of the training samples, while the 2DDCM approach enables the synthesis of outcomes with a more derivative style. As a result, the similarity between the synthesized sketches and the input images is greatly improved. Finally, a post-processing operation is performed to enhance the shadowed regions of the synthesized image by adding strong lines or curves to emphasize the lighting conditions. The experimental results confirm that the synthesized facial images are in good qualitative and quantitative agreement with the input images as well as the ground-truth sketches provided by the same artist. The representing power of the proposed framework is demonstrated by synthesizing facial sketches from input images with a wide variety of facial poses, lighting conditions, and races even when such images are not included in the training data set. Moreover, the practical applicability of the proposed framework is demonstrated by means of automatic facial recognition tests. PMID:27244737

    2015-09-01

    In this article we draw on Bury's theory of biographical disruption to discuss the meanings of, and emotional experiences related to, being diagnosed with breast cancer among southern Thai women. Qualitative methods, including in-depth interviewing and drawing methods, were used to collect data from 20 women with breast cancer. The women perceived breast cancer to be a rhok raai; an evil or dread disease. They believed that breast cancer would lead to death. The disruption in their biography occurred when they detected abnormalities indicating breast cancer. The women's narratives revealed their chaotic lives upon this diagnosis and the news precipitated in them shock, fear, anxiety and loss of hope. Although they experienced chaos and disruption, the women cultivated strategies that helped them cope with their experiences by accepting their fate and adhering to Buddhist beliefs and practices. Through their narratives of biographical disruption, the women in our study offer healthcare providers knowledge that could lead to an appreciation of their needs and concerns. This knowledge is crucial for health professionals who wish to provide emotional support to women who have been diagnosed with breast cancer in Thailand and elsewhere.

  1. Memorial and biographical history of Spain: El jinete polaco by Antonio Muñoz Molina

    2012-12-01

    Full Text Available The novel El jinete polaco by Antonio Muñoz Molina is a highly complex work in which the narrator mixes multiple plotlines in an effort to recreate or remember part of his family past. In the process, the collective memory of the town and people of Mágina (an allegoric space that represents the peasant life of the olive growers of southern Spain appears as a rich and contradictory montage of dreams and failures. And in a third level of discourse, the recent past of Spain also emerges through the main historic al events: the civil war, the protracted military government, and the economic development and current consolidation of democracy. In order to achieve this complex and ambitious narrative project, in El jinete polaco time is not represented as uninterrupted historical timeline but as the rich mixture of the simultaneous experiences of different life courses in terms of both values and cultural patterns in order to understand how the rapid social change affects relations between the various age groups. In other words, time is constructed as a synthesis of the biographical dimension within collective memory and major historical events. This paper seeks to point out the similarities and differences between biographical discourse, collective memory and history.

    This contribution is focused on the core tenet that the process of choice of occupation must encompass in its everyday routines the disabled person's biography, his or her life experiences, biographical self-appraisals as well as action orientations. Unless this is achieved, its professional strategies and interventions will remain prone to missing, or even counteracting, the biographical resources as well as thinking and perceptions of its clients. Biographical Diagnostics is presented here as a method seeking to access the individual in the process of choice of occupation in an understanding manner. It constitutes a new concept in terms of a biography-based, hermeneutic case approach conceived for implementation in the everyday routines of vocational rehabilitation. Two case examples serve to explicate the method of Biographical Diagnostics and set out the relevancy of a biographical orientation in the process of occupational choice. PMID:11579376

    2016-03-01

    Sketch maps are effective tools for assessing spatial memory. However, despite their widespread use in cognitive science research, sketch map analysis techniques remain unstandardized and carry limitations. In the present article, we present the Gardony Map Drawing Analyzer (GMDA), an open-source software package for sketch map analysis. GMDA combines novel and established analysis techniques into a graphical user interface that permits rapid computational sketch map analysis. GMDA calculates GMDA-unique measures based on pairwise comparisons between landmarks, as well as bidimensional regression parameters (Friedman & Kohler, 2003), which together reflect sketch map quality at two levels: configural and individual landmark. The configural measures assess the overall landmark configuration and provide a whole-map analysis. Individual landmark measures, introduced in GMDA, assess individual landmark placement and indicate how individual landmarks contribute to the configural scores. Together, these measures provide a more complete psychometric picture of sketch map analysis, allowing for comparisons between sketch maps and between landmarks. The calculated measures reflect specific and cognitively relevant aspects of interlandmark spatial relationships, including distance and angular representation. GMDA supports complex environments (up to 48 landmarks) and two software modes that capture aspects of maps not addressed by existing techniques, such as landmark size and shape variation and interlandmark containment relationships. We describe the software and its operation and present a formal specification of calculation procedures for its unique measures. We then validate the software by demonstrating the capabilities and reliability of its measures using simulation and experimental data. The most recent version of GMDA is available at www.aarongardony.com/tools/map-drawing-analyzer. PMID:25673320

  6. Time spent by people managing chronic obstructive pulmonary disease indicates biographical disruption.

    2014-01-01

    Since Bury's 1982 proposal that chronic illness creates biographical disruption for those who are living with it, there has been no effort to quantitatively measure such disruption. "Biographical disruption" refers to the substantial and directive influence that chronic illness can have over the course of a person's life. Qualitative research and time use studies have demonstrated that people with chronic illnesses spend considerable amounts of time managing their health, and that these demands may change over time. This study was designed to measure the time that older people with chronic illnesses spend on selected health practices as one indicator of biographical disruption. We look specifically at the time use of people with chronic obstructive pulmonary disease (COPD). As part of a larger time use survey, a recall questionnaire was mailed to 3,100 members of Lung Foundation Australia in 2011. A total of 681 responses were received (22.0% response rate), 611 of which were from people with COPD. Descriptive analyses were undertaken on the amount of time spent on selected health-related activities including personal care, nonclinical health-related care, and activity relating to health services. Almost all people with COPD report spending some time each day on personal or home-based health-related tasks, with a median time of 15 minutes per day spent on these activities. At the median, people also report spending about 30 minutes per day exercising, 2.2 hours per month (the equivalent of 4.4 minutes per day) on nonclinical health-related activities, and 4.1 hours per month (equivalent to 8.2 minutes per day) on clinical activities. Excluding exercise, the median total time spent on health-related activities was 17.8 hours per month (or 35.6 minutes per day). For people in the top 10% of time use, the total amount of time was more than 64.6 hours per month (or 2.2 hours per day) excluding exercise, and 104 hours per month (or 3.5 hours per day) including exercise

    Full Text Available The literature on the biographical backgrounds of entrepreneurs seems to contain many contradictory findings. This situation can partly be due to the assumption that samples of entrepreneurs were homogeneous rather than heterogeneous. It appears as if female entrepreneurs have been less well researched than their male counterparts. Differences in the biographical backgrounds and business situation of, respectively, the white and the black entrepreneurs in South Africa have been assumed but little empirical evidence exists in this respect. Black en-trepreneurs, and female entrepreneurs are in most developed societies' minority groups and have not specifically been studied in depth - hence the present study. The biographical and business backgrounds of 569 South African entrepreneurs (106 Black and 463 White; 136 female and 433 male were studied. One-way Analyses of Variance and Chi-squared followed by Discriminant analyses were carried out to determine whether, respectively, black and white entrepreneurs and male and female entrepreneurs differed in terms of the variables studied. Significant differences between the total group of male and female subjects were found on only five variables. White and black entrepreneurs differed statistically significantly on 16 of the 30 variables studied. Opsomming Die literatuur oor die biografiese agtergronde van entrepreneurs skyn baie teenstrydige bevindinge te bevat. Hierdie kan moontlik deels toegeskryf word aan die aanname dat steekproewe van entrepreneurs eerder homogeen eerder as heterogeen is.

    Edwin S. Shneidman (DOB: 1918-05-13; DOD: 2009-05-15) is a father of contemporary suicidology. His work reflects the intensive study of lives lived and deaths, especially suicides, and is the mirror to his mind. His contributions can be represented by five categories: psychological assessment, logic, Melville and Murray, suicide, and death. His works on suicide can be further divided into five parts: definitional and theoretical, suicide notes, administrative and programmatic, clinical and community, and psychological autopsy and postvention. In this article, not only are the selected works explicated, but also Dr. Shneidman's rather personal biographical notes are shared to allow the reader to understand one more unique individual's life lived, and his death: Edwin S. Shneidman. PMID:21034210

    This paper argues that tangible three dimensional sketching with textiles makes it more likely that these materials will be used when creating architectural spaces. Our research contributes to the more general idea that innovation in architecture and design can be stimulated by the exploration...... of new materials. With tangible three dimensional sketching, we mean an iterative process of physical model making. In two experiments with architectural students, all textile novices, spaces were modelled using a three dimensional sketching tool consisting of textiles, cardboard support and tools...... for giving form to and joining these materials. The chosen architectural task was how textiles could be used to regulate daylight by applying them to an exterior building skin or to interior spaces. Findings were that three different strategies were used: the tool was used to materialize, illustrate...

  15. Surface EMG-based Sketching Recognition Using Two Analysis Windows and Gene Expression Programming

    Science.gov (United States)

    2016-01-01

    Sketching is one of the most important processes in the conceptual stage of design. Previous studies have relied largely on the analyses of sketching process and outcomes; whereas surface electromyographic (sEMG) signals associated with sketching have received little attention. In this study, we propose a method in which 11 basic one-stroke sketching shapes are identified from the sEMG signals generated by the forearm and upper arm muscles from 4 subjects. Time domain features such as integrated electromyography, root mean square and mean absolute value were extracted with analysis windows of two length conditions for pattern recognition. After reducing data dimensionality using principal component analysis, the shapes were classified using Gene Expression Programming (GEP). The performance of the GEP classifier was compared to the Back Propagation neural network (BPNN) and the Elman neural network (ENN). Feature extraction with the short analysis window (250 ms with a 250 ms increment) improved the recognition rate by around 6.4% averagely compared with the long analysis window (2500 ms with a 2500 ms increment). The average recognition rate for the eleven basic one-stroke sketching patterns achieved by the GEP classifier was 96.26% in the training set and 95.62% in the test set, which was superior to the performance of the BPNN and ENN classifiers. The results show that the GEP classifier is able to perform well with either length of the analysis window. Thus, the proposed GEP model show promise for recognizing sketching based on sEMG signals.

Qualitative research and time use studies have demonstrated that people with chronic illnesses spend considerable amounts of time managing their health, and that these demands may change over time. This study was designed to measure the time that older people with chronic illnesses spend on selected health practices as one indicator of biographical disruption. We look specifically at the time use of people with chronic obstructive pulmonary disease (COPD. As part of a larger time use survey, a recall questionnaire was mailed to 3,100 members of Lung Foundation Australia in 2011. A total of 681 responses were received (22.0% response rate, 611 of which were from people with COPD. Descriptive analyses were undertaken on the amount of time spent on selected health-related activities including personal care, nonclinical health-related care, and activity relating to health services. Almost all people with COPD report spending some time each day on personal or home-based health-related tasks, with a median time of 15 minutes per day spent on these activities. At the median, people also report spending about 30 minutes per day exercising, 2.2 hours per month (the equivalent of 4.4 minutes per day on nonclinical health-related activities, and 4.1 hours per month (equivalent to 8.2 minutes per day on clinical activities. Excluding exercise, the median total time spent on health-related activities was 17.8 hours per month (or 35.6 minutes per day. For people in the

    Full Text Available This paper proposes a method of Content based image retrieval (CBIR using sketches, which is one of the most popular, rising research areas of the digital image processing. Most of the available image search tools, such as Google Images and Yahoo! Image search, are based on textual annotation of images. In these tools, images are manually annotated with keywords and then retrieved using text-based search methods. The performances of these systems are not satisfactory. The goal of CBIR is to extract visual content of an image automatically, like color, texture, or shape. The proposed method used to introduce the design and the creation of CBIR systems, which is based on a free hand sketch (Sketch based image retrieval – SBIR. In this method, we are using texture as feature for image retrieval. The texture features are obtained by using gray-level co-occurrence matrix (GLCM.This process can be used as coarse level in hierarchical CBIR that reduces the database size from very large set to a small one. This tiny database can further be scrutinized rigorously using the wavelets, edge detection, etc. The sketch based system allows users an intuitive access to search-tools. This process can be implemented in MATLAB simulation.

    2014-10-01

    This study aimed to identify biographical and behavioral factors associated with children pianists' motor skills using an objective assessment of a music-relevant motor task. Motor skills at the piano were assessed in 30 children pianists by measuring temporal unevenness in standardized scale playing using musical instrument digital interface (MIDI)-based scale analysis. Questionnaires were used to collect detailed information about the amount of time playing the piano, practice characteristics, attitudes toward music and practice, and the environment of music and practice. Associations between performance values and variables from the questionnaire were investigated using multivariable linear regression. A higher number of years playing the piano, more frequent parental involvement in the child's practice, more frequent practice of technical exercises, and greater enjoyment of practice and of the visual arts were associated with better motor performance. In addition to cumulative experience and aspects of practice, extrinsic motivational factors (e.g., parental interest) and intrinsic motivational factors (e.g., an artistic disposition) were associated with better performance on a musically-relevant motor task in children pianists.

    This study attempts to provide a concrete understanding to the embodied experience of HIV/AIDS. PLWHA have to cope with physical changes, especially lipodystrophy, caused by HIV and its treatment. These clinical manifestations make the disease socially visible and form a potential source of stigmatization. Visibility seems to transform the personal experience of this particular illness into a collective one. The changing body image and the stigma, which is often internalized by individuals, along with other consequences of chronic illness, such as alteration of life plans and social relationships, constitute new elements that appear in their life after diagnosis. These new experiences can break one's biographical continuity, especially in cases like HIV/AIDS. Semi-structured and in-depth interviews were conducted with 18 HIV-positive individuals (13 men, 5 women) with lipodystrophy. Their ages ranged from 36 to 65 years. The analysis of data revealed three main themes: loss of control over the body, ambivalence about visibility of HIV/AIDS, attributing positive meaning to HIV/AIDS. Physical changes caused by lipodystrophy are a source of dysphoria for PLWHA. This dissatisfaction was closely associated with the absence of control over their own body, due to the virus and the side effects of medication. Furthermore, it became evident that there was ambivalence among participants about the visibility of HIV, as it was in parallel a source of stigmatization, but also a part of their identity and biography. Results indicate that individuals were in search of meaning and constitute strategies in order to "answer" to the disruptive aspects of HIV. These were the normalization of illness, the integration into personal identity and the recognition of positive effects of HIV in their lives (e.g., stopping drug and alcohol abuse). Further research is required to identify the factors that determine the selection of each "answer" by these particular individuals who belong to

    Schroeder, David; Keefe, Daniel F

    2016-01-01

    We present Visualization-by-Sketching, a direct-manipulation user interface for designing new data visualizations. The goals are twofold: First, make the process of creating real, animated, data-driven visualizations of complex information more accessible to artists, graphic designers, and other visual experts with traditional, non-technical training. Second, support and enhance the role of human creativity in visualization design, enabling visual experimentation and workflows similar to what is possible with traditional artistic media. The approach is to conceive of visualization design as a combination of processes that are already closely linked with visual creativity: sketching, digital painting, image editing, and reacting to exemplars. Rather than studying and tweaking low-level algorithms and their parameters, designers create new visualizations by painting directly on top of a digital data canvas, sketching data glyphs, and arranging and blending together multiple layers of animated 2D graphics. This requires new algorithms and techniques to interpret painterly user input relative to data "under" the canvas, balance artistic freedom with the need to produce accurate data visualizations, and interactively explore large (e.g., terabyte-sized) multivariate datasets. Results demonstrate a variety of multivariate data visualization techniques can be rapidly recreated using the interface. More importantly, results and feedback from artists support the potential for interfaces in this style to attract new, creative users to the challenging task of designing more effective data visualizations and to help these users stay "in the creative zone" as they work.

  3. Face Recognition Algorithm for Photographs and Viewed Sketch Matching Using Score-Level Fusion

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available For criminal searches, the necessity of matching photographs with sketches is increasing. Previously, matching was performed manually by a human observer, a time‐consuming process whose accuracy can be affected by the level of human expertise. Therefore, we propose a new face recognition algorithm for photographs and sketches. This research is novel in the following three ways. First, to overcome the decrease in matching accuracy due to pose and illumination variation, we use eye alignment and retinex filtering to normalize pose, size and illumination. Second, we compare the performance of various face recognition methods, such as principal component analysis (PCA, local binary pattern (LBP, local non‐negative matrix factorization (LNMF, support vector machine‐discriminant analysis (SVM‐DA and modified census transform (MCT, for the matching of photographs and viewed sketches. Third, these five face recognition methods are combined on the basis of score‐ level fusion to enhance matching accuracy, thereby overcoming the performance limitations of single face recognition methods. Experimental results using a CUHK dataset showed that the accuracy of the proposed method is better than that of uni‐modal face recognition methods.

  4. Unsupervised polarimetric synthetic aperture radar image classification based on sketch map and adaptive Markov random field

    2016-04-01

    Markov random field (MRF) model is an effective tool for polarimetric synthetic aperture radar (PolSAR) image classification. However, due to the lack of suitable contextual information in conventional MRF methods, there is usually a contradiction between edge preservation and region homogeneity in the classification result. To preserve edge details and obtain homogeneous regions simultaneously, an adaptive MRF framework is proposed based on a polarimetric sketch map. The polarimetric sketch map can provide the edge positions and edge directions in detail, which can guide the selection of neighborhood structures. Specifically, the polarimetric sketch map is extracted to partition a PolSAR image into structural and nonstructural parts, and then adaptive neighborhoods are learned for two parts. For structural areas, geometric weighted neighborhood structures are constructed to preserve image details. For nonstructural areas, the maximum homogeneous regions are obtained to improve the region homogeneity. Experiments are taken on both the simulated and real PolSAR data, and the experimental results illustrate that the proposed method can obtain better performance on both region homogeneity and edge preservation than the state-of-the-art methods.

    We articulate a novel approach to geometric model completion via interactive sketches in this paper.First,the initial incomplete model (with holes) is decomposed into a base model and a high-frequency component,which represents global rough shape and geometric details,respectively.We then repair the base model via smooth hole-filling,and compute the geometry detail image using high frequency information.One novel element of our approach is that we allow users to interactively sketch a few structural curves that span across hole regions,with a goal to repair both local geometric details and global structure.With the help of local parameterization,we convert detailed geometry into gradient-domain images which can propagate along user-specified sketches.By integrating recovered gradient-domain images and base shape,we can generate a complete model that faithfully recovers both global structure and local details.The salient contribution of this paper is the unified approach for user interaction,global structure,and geometry details towards high-fidelity model completion.We demonstrate our new approach using a number of examples that exhibit salient global structure as well as local geometry details.

  6. A Visual Navigation Method of Mobile Robot Using a Sketched Semantic Map

    Full Text Available A new visual navigation method for a mobile robot is proposed in this paper. Its originality lies in integrating a sketched map with a semantic map together for the robot’s navigation and in using unified tags to help recognize landmarks. In this sketched semantic map, the outline and semantic information of key referenced objects are used to represent themselves and a rough route for the robot’s navigation is also sketched. Over the course of robot navigation along the route, and in order to easily recognize the referenced objects from the complex background, a kind of unified label is designed and pasted on the potential referenced objects in advance. A recognition method based on the Pseudo-Zernike Moment and the Normalized Moment of Inertia is used to compute the matching degree between the real‐time image of the referenced object and its similar outline in a database. In addition, the odometer information is also fused so as to roughly localize the robot. Finally, through a series of experiments, the advantage and efficiency of the new navigation method with real‐time dynamic obstacle avoidance are testified with the help of the imprecise real map and route.

  7. Visualization-by-Sketching: An Artist's Interface for Creating Multivariate Time-Varying Data Visualizations.

    Schroeder, David; Keefe, Daniel F

    2016-01-01

    We present Visualization-by-Sketching, a direct-manipulation user interface for designing new data visualizations. The goals are twofold: First, make the process of creating real, animated, data-driven visualizations of complex information more accessible to artists, graphic designers, and other visual experts with traditional, non-technical training. Second, support and enhance the role of human creativity in visualization design, enabling visual experimentation and workflows similar to what is possible with traditional artistic media. The approach is to conceive of visualization design as a combination of processes that are already closely linked with visual creativity: sketching, digital painting, image editing, and reacting to exemplars. Rather than studying and tweaking low-level algorithms and their parameters, designers create new visualizations by painting directly on top of a digital data canvas, sketching data glyphs, and arranging and blending together multiple layers of animated 2D graphics. This requires new algorithms and techniques to interpret painterly user input relative to data "under" the canvas, balance artistic freedom with the need to produce accurate data visualizations, and interactively explore large (e.g., terabyte-sized) multivariate datasets. Results demonstrate a variety of multivariate data visualization techniques can be rapidly recreated using the interface. More importantly, results and feedback from artists support the potential for interfaces in this style to attract new, creative users to the challenging task of designing more effective data visualizations and to help these users stay "in the creative zone" as they work.

  10. Comparative evaluation of two commercial PET scanners, ECAT EXACT HR+ and Biograph 2, using GATE

    International Nuclear Information System (INIS)

    Geant4 application for tomographic emission (GATE) is a generic Monte Carlo simulation platform based on a general-purpose code GEANT4 and designed to simulate positron emission tomography (PET) and single photon emission tomography systems. Monte Carlo simulations are used in nuclear medicine to model imaging systems and develop and assess tomographic reconstruction algorithms and correction methods for improved image quantification. The purpose of this study is to validate two GATE models of the commercial available PET scanner HR+ and the PET/CT Biograph 2. The geometry of the system components has been described in GATE, including detector ring, crystal blocks, PMTs etc. The energy and spatial resolution of the scanners as given by the manufacturers have been taken into account. The GATE simulated results are compared directly to experimental data obtained using a number of NEMA NU-2-2001 performance protocols, including spatial resolution, sensitivity and scatter fraction. All the respective phantoms are precisely modeled. Furthermore, an approximate dead-time model both at the level of single and coincidence events was developed so that the simulated count rate curve can satisfactorily match the experimental count rate performance curve for each scanner In addition a software tool was developed to build the sinograms from the simulated data and import them into the software for tomographic image reconstruction where the reconstruction algorithm of FBP3DRP was applied. An agreement of less than 0.8 mm was obtained between the spatial resolution of the simulated system and the experimental results. Also the simulated scatter fraction for the NEMA NU 2-2001 scatter phantom matched the experimental results to within 3% of measured values. Finally the ratio of the simulated sensitivities with sources radially offset 0 and 10 cm from the central axis of each of the two scanners reaches an agreement of less than 1% between the simulated and experimental values.

    A method for the assessment of six premorbid personality types from biographical data in psychiatric case histories is described. Trained raters have to fill in a list comprising 106 items as descriptors of a patient's premorbid behavioural development. The assignment to the types in question (the "manic type" and its rare variant, the "happy-go-lucky type", the "melancholic type", the "anxious insecure type" and its rare variant, the "unrealistic dreamy type", and finally, the "nervous tense type") is computed on the basis of the item scores by forming type scores and comparing their height intraindividually. The subject under study is assigned to the type reaching the comparatively highest value. Two raters independently analyzed 261 records from which all information on mental disorders in family members and the patient himself/herself as well as all biographical data from the first manifestation of a symptom disorder onwards had been erased by technical assistants. In 106 of the records, a global assignment to the types of premorbid personality had already been performed by one of the authors of the typology. The scores for the same type assessed by the two ratings correlated highly with each other (0.77 to 0.80), the concordance of types reached a kappa-value of 0.55 (P < 0.001), and the results of the operationalized typing agreed in the same order with the result of global typing in the subsample of n = 106.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. A DANE WRITES ABOUT CHOPIN. PEER HULTBERG’S “PRELUDES” AS AN EXAMPLE OF A CONTEMPORARY DANISH BIOGRAPHICAL NOVEL

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The paper A Dane writes about Chopin. Peer Hultberg’s “Preludes” as an example of a contemporary Danish biographical novel concerns the condition of a contemporary Danish biographical novel. The main focus is put on Peer Hultberg’s work Preludes on the famous Polish composer, Fryderyk Chopin. The author of the paper uses the definition of a biographical novel as Maria Jasinska understands it, and the definition of a modernist literary novel by Stephen J. Walton. The article also addresses other contemporary biographical novels written in Scandinavia. Its main aim is to examine in what respects Hultberg’s novel deviates from the standards of a modernist biographical novel. The research is based on four criteria: focus put on one character, chronological structure of the narration, including all life stages, presence of the milestones in the protagonist’s professional career and appearance of authentic characters in the novel’s plot. As it turns out, Preludes hardly fulfills any of the above-mentioned requirements. Although the protagonist is clearly defined, the polyphonic structure of the narration makes it difficult to focus on one character only. The chronological composition is present, but the plot does not include any of the milestones in the composer’s career, since the novel only concerns his childhood. As to authentic characters, they play a peripheral role in the novel’s plot. One can therefore assume that Peer Hultberg’s Preludes is a postmodernist biographical novel, where a fragment replaces the whole, and one stage of life, namely childhood, is capable of telling a story of the origin of genius.

  14. Enhancing ASTRO101 Student Engagement Using Student-Created ScienceSKETCHES

    2016-01-01

    As astronomy teaching faculty are changing their teaching strategies from those less desirable approaches that allow students to passively listen to professor-centered, information-lectures to more desirable, active-student engagement classrooms characterized by active learning, ASTRO 101 professors are looking for more ways to help students learn to participate in authentic scientific practices. This is consistent with notion advocated by the NRC that students should practice scientific thinking, scientific discourse, and scientific practices while learning science. Noticing that much informal scientific discussion is mediated by sketches—such as those occasionally lively discussions held after hours during scientific conferences—scholars at the CAPER Center for Astronomy & Physics Education Research have been piloting a series of active learning tasks where students are challenged to create scientific drawings to illustrate their understanding of astronomical phenomena or structures. Known informally as ScienceSKETCHES, examples of these tasks challenge students to illustrate: the spectral curve differences between high and low mass stars; the differences among galaxy shapes; the distribution of stars for the Andromeda Galaxy in terms of luminosity versus temperature; old and young planetary surfaces; or the relationships between distances and speeds of orbiting objects. Although our initial testing has focused on predominately on paper and pencil tasks, with the occasional cell phone picture of a ScienceSKETCH being texted to the professor, the electronic-based teaching world is nearly ready to support these sorts of drawing tasks. Already, the ability to complete and submit scientific sketches is becoming commonplace across electronic learning platforms, including shared white-boarding in many desktop videoconferencing systems, and handheld device learning systems for interactive classrooms, like those from Learning Catalytics, among many others.

    Full Text Available Knowledge dissemination is an emerging issue in population studies, both in terms of ethics and data quality. The challenge is especially important in long term follow-up surveys and it requires methodological imagination when the population is illiterate. The paper presents the dissemination project developed in a demographic surveillance system implemented in rural Mali over the last 20 years. After basic experience of document transfer, the feedback strategy was developed through audiovisual shows and theatre sketches. The advantages and drawbacks of these media are discussed, in terms of scientific communication and the construction of dialogue with the target population.

    Full Text Available Lawu is a severely endangered, undocumented Ngwi (Loloish language spoken in Yunnan, China. This paper presents a preliminary sketch of Lawu phonology based on lexico-phonetic data recorded from two speakers in 2008, with special attention to the tone splits and mergers that distinguish Lawu from other Ngwi languages. All tone categories except Proto-Ngwi Tone *3, a mid level pitch, have split, conditioned by the voicing of the initial segment. In the conditioning and effect of these tone splits, Lawu shows affinity with other Central Ngwi languages such as Lisu and Lahu and is provisionally classified as a Central Ngwi language.

  1. Eight Noble Opinions and the Economic Crisis: Four Literary-philosophical Sketches à la Eduardo Galeano

    2010-03-01

    Full Text Available Four literary-philosophical skecthes are presented here in order to celebrate the ten-year anniversary of the publication of the official English translation of one of Eduardo Galeano's most important books: Upside Down: A Primer for the Looking-glass World. Each of these four sketches deals with the current economic crisis, though from different perspectives of analysis, and attempts to make use of the vibrant and creative sylistic devices characterising Galeano's works, particularly Upside Down. In this book, Galeano explored insightfully the roots of the crisis to come. His critical conclusions were analogous to those of another eccentric observer of the most notable economic phenomena of the 1990s, John McMurtry, whose perception of the looming crisis was even more profound and technical. Therefore, also this Canadian thinker, indeed his theory of value, is evoked in the four sketches, for McMurtry's onto-axiology reveals the ongoing contradiction between the relentless search for profit of the mostly virtual global script type=text/javascript src=http://nome.st5.stefna.is/joomla/plugins/editors/jce/tiny_mce/themes/advanced/langs/en.js?version=156/scriptscript type=text/javascript src=http://nome.st5.stefna.is/joomla/plugins/editors/jce/tiny_mce/plugins/advcode/langs/en.js?version=156/scripteconomy and the requirements of natural and human life.

  2. The Creation and Modification of 3D Models Using Sketches and Curves

    Science.gov (United States)

    Kara, Levent Burak; Shimada, Kenji

    This chapter describes a pen-based modeling system for the styling design of 3D objects. Our system is tailored toward the rapid and natural design of styling features such as freeform curves and surfaces. In a typical scenario, the user begins by constructing the base wireframe model of the design object. For this, the user first sketches the initial feature curves on a very rough and simplified 3D template model. This template model acts as a platform that helps anchor users' initial strokes in 3D space. Once the initial curves comprising the wireframe are constructed, the base 3D template is removed, leaving the user with a set of 3D curves. Next, through direct sketching, the user modifies the initially created curves to give them the precise desired form. After the desired wireframe is obtained, the user constructs interpolating surfaces that cover the wireframe. Finally, using two physically-based deformation tools, the user modifies the newly created surfaces to the desired shapes. Once the basic wireframe and surfaces are created, further details can be added using the same strategy of curve creation, curve modification, surface creation, and finally surface modification.

  3. Beyond data collection in digital mapping: interpretation, sketching and thought process elements in geological map making

    2016-04-01

    Geological mapping techniques have advanced significantly in recent years from paper fieldslips to Toughbook, smartphone and tablet mapping; but how do the methods used to create a geological map affect the thought processes that result in the final map interpretation? Geological maps have many key roles in the field of geosciences including understanding geological processes and geometries in 3D, interpreting geological histories and understanding stratigraphic relationships in 2D and 3D. Here we consider the impact of the methods used to create a map on the thought processes that result in the final geological map interpretation. As mapping technology has advanced in recent years, the way in which we produce geological maps has also changed. Traditional geological mapping is undertaken using paper fieldslips, pencils and compass clinometers. The map interpretation evolves through time as data is collected. This interpretive process that results in the final geological map is often supported by recording in a field notebook, observations, ideas and alternative geological models explored with the use of sketches and evolutionary diagrams. In combination the field map and notebook can be used to challenge the map interpretation and consider its uncertainties. These uncertainties and the balance of data to interpretation are often lost in the creation of published 'fair' copy geological maps. The advent of Toughbooks, smartphones and tablets in the production of geological maps has changed the process of map creation. Digital data collection, particularly through the use of inbuilt gyrometers in phones and tablets, has changed smartphones into geological mapping tools that can be used to collect lots of geological data quickly. With GPS functionality this data is also geospatially located, assuming good GPS connectivity, and can be linked to georeferenced infield photography.

    Loewenberg, P

    1988-01-01

    Freud's paper is re-examined and placed in biographical and historical context, Moses and monotheism (1934-1938) is treated as a parallel text. Freud's ironic scepticism is viewed against the background of Thomas Mann's 1936 idealization of psychoanalysis. Freud was a sick and dying man in 1937 with every reason for personal pessimism. The political setting was the triumph of fascism in Austria and the impending seizure of Austria by Hitler. Freud fantasized the protection of psychoanalysis by the Roman Catholic Church. The paper is a polemic against the theories of Ferenczi, Adler, and Rank. Contemporaneous defence of prophylactic analysis by Fenichel is reviewed. Freud's political judgement of the moral equivalence of Social Democracy and fascism is critiqued. Freud's injunction to periodic re-analysis and his vision of analysis as 'unending' is supported. The possibility of intergenerational prophylaxis is presented. PMID:3042656

  7. Using evolutionary design to interactively sketch car silhouettes and stimulate designer's creativity

    CERN Document Server

    Cluzel, François; Dihlmann, Markus; 10.1016/j.engappai.2012.02.011

    2013-01-01

    An Interactive Genetic Algorithm is proposed to progressively sketch the desired side-view of a car profile. It adopts a Fourier decomposition of a 2D profile as the genotype, and proposes a cross-over mechanism. In addition, a formula function of two genes' discrepancies is fitted to the perceived dissimilarity between two car profiles. This similarity index is intensively used, throughout a series of user tests, to highlight the added value of the IGA compared to a systematic car shape exploration, to prove its ability to create superior satisfactory designs and to stimulate designer's creativity. These tests have involved six designers with a design goal defined by a semantic attribute. The results reveal that if "friendly" is diversely interpreted in terms of car shapes, "sportive" denotes a very conventional representation which may be a limitation for shape renewal.

    2012-01-01

      Humor is a pervasive human phenomenon. It is observable in many spheres and aspects of life in various human interactions. Humor plays an important role in our social life. Relevance Theory provides a new perspective on the analysis of humor interpretation. From a relevance-theoretic point of view, humor interpretation is a cognitive process in which the addressee is willing to sacrifice more cognitive effort to access the more covert interpretation in pursuit of the extra ef ect—amusement brought about by comic sketch. The conclusion is made in the end in which the Relevance Theory works as it plays such an important role in analyzing humor production that helps us understand and appreciate Zhao’s humor better.

    Barrett, Anne E; Pai, Manacy

    2008-01-01

    Much of the literature on teaching gerontology derives from experiences in face-to-face settings. There is limited discussion of either the applicability of teaching techniques drawn from the traditional setting to the online environment or the development of novel strategies to engage distance students of aging. We developed and assessed an exercise designed to stimulate an online, asynchronous discussion of ageism in a Web-based social gerontology course. The exercise required students to analyze patterns found in sketches of elders drawn by themselves and their peers. The activity, which was favorably evaluated by our students, provided a springboard for discussion of the origins and consequences of ageism, as well as issues at the intersection of gender and age inequality.

    2013-04-01

    The Sketch Match approach for Sulina pilot case was carried out in the frame of the project "People for Ecosystem Based Governance in Assessing Sustainable Development of Ocean and Coast" - PEGASO, funded by the Seventh Framework Programme. The PEGASO project has been designed to identify common threats and solutions in relation to the long-term sustainable development and environmental protection of coastal zones bordering the Mediterranean and Black Seas in ways relevant to the implementation of the Integrated Coastal Zone Management Protocol (ICZM) for the Mediterranean. PEGASO will use the model of the existing ICZM Protocol for the Mediterranean and adjust it to the needs of the Black Sea through innovative actions, one of them being Refine and develop efficient and easy to use tools for making sustainability assessments in the coastal zone tested through a number of relevant pilot sites. Thus, for the Romania case study, the Sketch Match approach was selected, being an interactive public participation planning method, developed by the Dutch Government, and applied for Sulina area in order to stimulate support and involvement from stakeholders regarding Integrated Coastal Zone Management Protocol by consulting and involving these people in the planning process and making use of a coherent package of interactive methods. Participants were representatives of a wide range of stakeholders, varying from local fisherman to representatives of the Local and County council and Danube Delta Biosphere Reserve Authority. They participated in a two-day design session, focused on problems and potentials of the area, with the aim to work out possible solutions for an integrated coastal spatial planning, focusing on the parallel enhance of the various local functions in the spatial design (coastal area protection next to industry, tourism, nature, recreation, and other activities).

  15. Divine Doctors: The Construction of the Image of Three Greek Physicians in Islamic Biographical Dictionaries of Physicians

    Directory of Open Access Journals (Sweden)

    Abbou Hershkovits, Keren

    2013-06-01

    Full Text Available This paper examines the way authors of three medieval Islamic biographical dictionaries portrayed the lives, behavior and characteristics of three key figures of Greco-Roman medicine, Asclepius, Hippocrates and Galen. Particular attention was given to the vocabulary and phrasing used in the biographies, and associations with other literary genres or figures. An analysis of these biographies demonstrates a significant resemblance between the portrayal of these Greco-Roman physicians and the lives of prophetic figures in Islam, and especially that of the Prophet Muḥammad. In addition, these biographies align with features attributed to pious Muslims. This study demonstrates that Muslim biographers constructed these biographies as part of a general tendency to associate medicine with Islam, and the origins of medical knowledge with prophetic wisdom. This study mantains that the connotations and use of this particular terminology allows for a positive view of the science of medicine in these Islamic compositions in which they were included.Este artículo analiza la manera en que los autores de tres diccionarios biográficos islámicos medievales retrataron la vida y características de las tres figuras más destacadas de la medicina greco-romana: Asclepio, Hipócrates y Galeno.

El análisis de estas biografías revela un considerable parecido entre el retrato de estos tres médicos greco-romanos y la vida de algunos profetas en el Islam, especialmente la del Profeta Muḥammad. Asimismo, estas biografías presentan elementos atribuidos a musulmanes piadosos. Este estudio demuestra que los biógrafos musulmanes construyeron esas biografías como parte de una tendencia general a asociar la medicina con el Islam y los orígenes del saber médico con la sabiduría profética. Igualmente, sostiene que

    Full Text Available Two months after the outbreak of the Anglo-Boer War a series of battles took place which shook Britain. These were Stormberg (10 December1899, Magersfontein (11 December 1899 and Colenso (15 December 1899. All had been reverses for the British army and had taken place within a week which became known as Black Week - a phrase coined by the British Liberal Party politician Asquith. Great Britain was regarded as having the world's most powerful army at the time and the losses suffered against the Boers resulted in humiliation and anguish for the British nation. However, nowhere was the anguish greater than in Scotland for at Magersfontein the Highland Brigade had fared badly suffering severe losses including their commander, Major-General Andrew Wauchope, killed in action. As Conan Doyle put it, "Never has Scotland had a more grievous day than this at Magersfontein. She had always given her best blood with lavish generosity for the Empire, but it may be doubted if any single battle has ever put' so many families of high and low, into mourning from the Tweed to Caithness shore." (Doyle, 1900:24 In the words of biographer William Baird "the empire has lost one of its noblest and best, a hero has gone down to his rest ere his full life's work was done". (Baird, 1902:196 Although these statements may seem somewhat flowery and were expressed during a period of much patriotic fervour, they nevertheless indicate the emotional reaction to Andrew Wauchope's untimely death.

    Chronic obstructive pulmonary disease (COPD) is a progressive illness that changes the lives of patients and their spouses dramatically. The aim of this paper is to show how spouses of COPD patients integrate their tasks as informal carers with their role as spouses and the tensions and challenges involved in this. The study draws on qualitative interviews with spouses of COPD patients, recruited from the patient pool of ambulatory pulmonary services of two hospitals in Oslo, Norway. The spouses described their great efforts to re-establish normality and continuity in their everyday lives. Accomplishing this was a delicate process because they faced several dilemmas in this work. They balanced the need to sustain the independence and integrity of both parties against the need to ensure safety and deal with the progression of the illness. We propose 'biographical we' as a concept that can highlight the great effort spouses put into establishing a sense of continuity in their lives. In times when healthcare policy involves mobilising informal caregiving resources, an awareness of the complexity of caregiving relationships is crucial when developing appropriate support for informal carers.

    Full Text Available Archaeological research provides the widest opportunity for researchers to analyse various aspects and disciplines appropriate to the subject and the object of choice. Subject and object selection is the work of exploration artefacts found in particular sites and archaeological heritage. Exploration and excavation on of a world heritage site such as Lenggong enables researchers to uncover various archaeological artefacts that are rich and meaningful. To find evidence of the strength and benefits of an artefact, further studies on each artefact should be carried out continuously. This essay will track the wisdom of the ancient artists use to produce paintings in a limestone cave in Lenggong, Perak, using spray techniques. Some artefacts that are identified as cave paintings show a very interesting sketch technique that are unique and special. This essay will also examine some of the cave paintings in other caves in Perak and also other caves in several countries as comparison. Studies involving cave paintings in Malaysia are new compared to Western countries. Thus, the study of one of the technique which is spray technique can open the eyes of the audience to acknowledge and recognise the ancient heritage. It also hoped that this study is able to increase the body of knowledge that goes beyond the boundaries of the arts district and the country.

  3. Fractality of Massive Graphs: Scalable Analysis with Sketch-Based Box-Covering Algorithm

    2016-01-01

    Analysis and modeling of networked objects are fundamental pieces of modern data mining. Most real-world networks, from biological to social ones, are known to have common structural properties. These properties allow us to model the growth processes of networks and to develop useful algorithms. One remarkable example is the fractality of networks, which suggests the self-similar organization of global network structure. To determine the fractality of a network, we need to solve the so-called box-covering problem, where preceding algorithms are not feasible for large-scale networks. The lack of an efficient algorithm prevents us from investigating the fractal nature of large-scale networks. To overcome this issue, we propose a new box-covering algorithm based on recently emerging sketching techniques. We theoretically show that it works in near-linear time with a guarantee of solution accuracy. In experiments, we have confirmed that the algorithm enables us to study the fractality of million-scale networks fo...

    Full Text Available This paper presents a functional design sketch for the resource management module of a highly scalable collaborative system. Small and medium enterprises require such tools in order to benefit from and develop innovative business ideas and technologies. As computing power is a modern increasing demand and no easy and cheap solutions are defined, especially small companies or emerging business projects abide a more accessible alternative. Our work targets to settle a model for how P2P architecture can be used as infrastructure for a collaborative system that delivers resource access services. We are focused on finding a workable collaborative strategy between peers so that the system offers a cheap, trustable and quality service. Thus, in this phase we are not concerned about solutions for a specific type of task to be executed by peers, but only considering CPU power as resource. This work concerns the resource management module as a part of a larger project in which we aim to build a collaborative system for businesses with important resource demands

    While growing up in Cedar Rapids, Iowa, Milton Wright, The Wright Brothers Father, liked to purchase toys for his sons that he hoped would stimulate their imagination. One of the most memorable gifts was a toy helicopter that was designed by the French aeronautical experimenter Alphonse P naud. Milton gave his sons this gift in 1878, and, though it was a simple device with a stick bound to a four-blade rotor set in a spindle, it had the intended effect it caused them to dream. Twenty-five years separated the gift of this toy and their invention of the airplane, yet the Wright brothers were convinced it had exerted an important influence. Tom Crouch argued in The Bishop's Boys that toys like these perfectly illustrated the significance of play for technological innovation. He wrote, rotary-wing toys were to intrigue and inspire generations of children, a few of whom would, as adults, attempt to realize the dream of flight for themselves. If the first powered flight on 17 December 1903 represented a childhood dream realized, it was only the first step in the rapid evolution of the airplane from their flimsy kite-like contraption of wood and cloth to jet airliners and rockets in space. And, as extraordinary as the achievement of powered flight seemed in 1903, before the end of the century, space travel also would become a dream realized. Soviet astronaut Yuri Gagarin first circumnavigated Earth in April 1961, and, eight years later, American astronauts took the first steps for humankind on the Moon. It is with great pleasure that we introduce Realizing the Dream: Biographical Essays in Honor of the Centennial of Flight. These essays in celebration of the Wright brothers first flight 100 years ago grew out of presentations by a group of prominent scholars in 2003 at a conference sponsored by the NASA History Division and held at the Great Lakes Science Center in Cleveland, Ohio. The volume focuses on the careers of some of the many men and women who helped to realize

    Edward Teller died on September 9, 2003 in Stanford, California at the age of 95. He was both one of the great theoretical physicists of the twentieth century and a leading figure in the development of nuclear weapons and broader defense advocacy. Teller's work in physics, spanning many decades of the twentieth century, includes some of the most fundamental insights in the quantum behaviors of molecules and their spectra, nuclei, surfaces, solid state and spin systems, and plasmas. In the defense arena, Teller is best known for his key insight that made thermonuclear weapons possible. Teller was both a great scientific collaborator and physics teacher at all levels, known for his openness, generosity, personal warmth, and powerful physical intuition. Many of his graduate students went on to illustrious careers.

  15. [The advantage of a modern operational approach to the diagnosis of mental disorders. The case of the Bavarian King Ludwig II--an example from biographical research].

    Science.gov (United States)

    von Zerssen, D

    2013-05-01

    Worldwide discrepancies in the classification, terminology and diagnosis of mental disorders have induced efforts for unification after World War II. This led to the introduction of an operational diagnostic approach according to strict criteria, at the same time taking into account the comorbidity of disorders. However, this approach is still not routinely used. The consequences of this deficiency are demonstrated here by an example from biographical research referring to the Bavarian King Ludwig II. The study is based on an extensive search of the relevant literature. Although the pathography of this Bavarian king is well documented, the diagnoses published between 1910 and 2010 by altogether 21 specialists, are distributed rather chaotically over 24 diagnostic categories of the ICD-10. Merely in the (probably wrong) diagnosis of a schizophrenic psychosis is there agreement among half of the authors. This is concordant with the expert diagnosis of paranoia by von Gudden and his colleagues (1886) when considering the then contemporary concept of the disorder. According to modern diagnostic principles almost half of the 24 diagnoses can be confirmed. The others have to be regarded as false diagnoses. The conclusion is that modern principles of the diagnosis of mental disorders should be applied according to internationally accepted diagnostic manuals. This approach should be used in, but is not exclusive to, biographical research. Precondition is, of course, the exact knowledge and careful application of these principles.

  16. Enhancement of the Adaptive Shape Variants Average Values by Using Eight Movement Directions for Multi-Features Detection of Facial Sketch

    2012-04-01

    Full Text Available This paper aims to detect multi features of a facial sketch by using a novel approach. The detection of multi features of facial sketch has been conducted by several researchers, but they mainly considered frontal face sketches as object samples. In fact, the detection of multi features of facial sketch with certain angle is very important to assist police for describing the criminal’s face, when criminal’s face only appears on certain angle. Integration of the maximum line gradient value enhancement and the level set methods was implemented to detect facial features sketches with tilt angle to 15 degrees. However, these methods tend to move towards non features when there are a lot of graffiti around the shape. To overcome this weakness, the author proposes a novel approach to move the shape by adding a parameter to control the movement based on enhancement of the adaptive shape variants average values with 8 movement directions. The experimental results show that the proposed method can improve the detection accuracy up to 92.74%.

    GAMOS simulation code based on Geant4 is a very powerful tool for the design and modeling optimization on Positron Emission Tomography (PET) systems. In order to obtain a proper image quality, it results to be extremely important determine the optimal activity which is going to be delivered. For this reason a study about the internal system parameters that affects image quality, such as scatter fraction (SF) and the count rate equivalent noise (NEC), has been carried out. The study involves the comparison of experimental measures on both parameters, with those obtained by Monte Carlo simulation of Siemens Pet Biograph 6 True Point with True V option. Based on simulations results, a paralizable dead-time model that adjusts, depending on the activity provided, the proper dead-time for scanner detectors. Also a study about the variation of this proper dead-time with the activity has been carried out. (Author)

    Benzodiazepines are group of drugs used mainly as sedatives, hypnotics, muscle relaxants, and anti-epileptics. Tapering off benzodiazepines is, for some users, a painful, traumatic, and protracted process. In this article, I use an autoethnographic approach, adopting the metaphor of water, to examine heuristically my experience of iatrogenic illness and recovery. I draw on personal journals and blog entries and former users' narratives to consider the particular form of biographical disruption associated with benzodiazepines and the processes involved in identity reconstruction. I emphasize the role of the online community in providing benzodiazepine users such as myself with a co-cultural community through which to share a voice and make sense of our experiences. I explain how the success stories of former users provided me with the hope that I, the "medical victim," could become the "victor" and in the process construct a new life and fresh identity.

    2010-10-15

    This study is a prelude to the definition of a new synthetic parameter inserted in a 2D abacus. This parameter: the Amlouk-Boubaker optothermal expansivity <{psi}{sub AB}>, is defined, for a given PV-T material, as a thermal diffusivity-to-optical effective absorptivity ratio. This parameter's unit evokes a heat flow velocity inside the material. Consequently, the parameter {psi}{sub AB} could be combined with the already known bandgap energy E{sub g}, in order to establish a 2D abacus. A sketched scheme of the 2D abacus is proposed as a guide for investigation and evaluation of PV-T candidate materials like metal oxides, amorphous silicon, zinc-doped binary compounds, and hydrogenated amorphous carbon. Using this abacus, designers will be able to compare solar energy-related materials on the basis of conjoint optical and thermal efficiency. (author)

Pretty soon I met a talented director, writer and actor named Rani O'Brien and together we created the Lollygaggers—a sketch comedy musical about climate change for kids of all ages. For 16 weeks in 2014, The Lollygaggers ran in the Second City Studio Theater on Hollywood Blvd, brining laughs and lessons on climate change to a wide audience using puppets, characters and songs. This presentation will focus on how climate change and comedy can unite, how the Lollygaggers came to be, and will include a song from the show.

  4. Statistical safety evaluation of BWR turbine trip scenario using coupled neutron kinetics and thermal hydraulics analysis code SKETCH-INS/TRACE5.0

    International Nuclear Information System (INIS)

    The Best Estimate Plus Uncertainty (BEPU) method has been prepared for the regulatory cross-check analysis at Japan Nuclear Energy Safety Organization (JNES) on base of the three-dimensional neutron-kinetics/thermal-hydraulics coupled code SKETCH-INS/TRACE5.0. In the preparation, TRACE5.0 is verified against the large-scale thermal-hydraulic tests carried out with NUPEC facility. These tests were focused on the pressure drop of steam-liquid two phase flow and void fraction distribution. From the comparison of the experimental data with other codes (RELAP5/MOD3.3 and TRAC-BF1), TRACE5.0 was judged better than other codes. It was confirmed that TRACE5.0 has high reliability for thermal hydraulics behavior and are used as a best-estimate code for the statistical safety evaluation. Next, the coupled code SKETCH-INS/TRACE5.0 was applied to turbine trip tests performed at the Peach Bottom-2 BWR4 Plant. The turbine trip event shows the rapid power peak due to the voids collapse with the pressure increase. The analyzed peak value of core power is better simulated than the previous version SKETCH-INS/TRAC-BF1. And the statistical safety evaluation using SKETCH-INS/TRACE5.0 was applied to the loss of load transient for examining the influence of the choice of sampling method. (author)

  9. GATE Monte Carlo simulations for variations of an integrated PET/MR hybrid imaging system based on the Biograph mMR model

    International Nuclear Information System (INIS)

    A simulation toolkit, GATE (Geant4 Application for Tomographic Emission), was used to develop an accurate Monte Carlo (MC) simulation of a fully integrated 3T PET/MR hybrid imaging system (Siemens Biograph mMR). The PET/MR components of the Biograph mMR were simulated in order to allow a detailed study of variations of the system design on the PET performance, which are not easy to access and measure on a real PET/MR system. The 3T static magnetic field of the MR system was taken into account in all Monte Carlo simulations. The validation of the MC model was carried out against actual measurements performed on the PET/MR system by following the NEMA (National Electrical Manufacturers Association) NU 2-2007 standard. The comparison of simulated and experimental performance measurements included spatial resolution, sensitivity, scatter fraction, and count rate capability. The validated system model was then used for two different applications. The first application focused on investigating the effect of an extension of the PET field-of-view on the PET performance of the PET/MR system. The second application deals with simulating a modified system timing resolution and coincidence time window of the PET detector electronics in order to simulate time-of-flight (TOF) PET detection. A dedicated phantom was modeled to investigate the impact of TOF on overall PET image quality. Simulation results showed that the overall divergence between simulated and measured data was found to be less than 10%. Varying the detector geometry showed that the system sensitivity and noise equivalent count rate of the PET/MR system increased progressively with an increasing number of axial detector block rings, as to be expected. TOF-based PET reconstructions of the modeled phantom showed an improvement in signal-to-noise ratio and image contrast to the conventional non-TOF PET reconstructions. In conclusion, the validated MC simulation model of an integrated PET/MR system with an overall

    画像的画风识别广泛应用于名画甄别和刑侦破案领域。文中提出基于多核学习的画像画风的识别算法。首先根据艺术评论家从画像部件的处理方式鉴定画像画风的方法,从画像中提取脸、左眼、右眼、鼻和嘴5个部件。然后根据画家从画像的明暗度和画像作者的绘画笔法识别画像画风的方法,从每个部件上提取灰度直方图特征、灰度矩特征、快速鲁棒特征和多尺度的局部二值模式特征。最后通过多核学习将不同部件和不同特征融合以进行画像画风的识别。实验表明,文中算法性能较好,能取得较高识别率。%The drawing style recognition of facial sketches is widely used for painting authentication and criminal investigation. A drawing style recognition algorithm of facial sketch based on multiple kernel learning is presented. Firstly, according to the way of art critics recognize the drawing style of facial sketch, five parts, the face part, left eye part, right eye part, nose part and mouth part, are extracted from the facial sketch. Then, gray histogram feature, gray moment feature, speeded-up robust feature and multiscale local binary pattern feature are extracted from each part on the basis of artistsˊ different understandings of lights and shadows on a face and various usages of the pencil . Finally, different parts and features are integrated and the drawing styles of facial sketches are classified by multiple kernel learning. Experimental results demonstrate that the proposed algorithm has better performance and obtains higher recognition rates.

We propose a method to model flowers of solid shape. Our method separates individual flower modeling and inflorescence modeling pro-cedures into structure and geometry modeling. We incorporate interactive editing gestures to allow user to edit structure parameters freely onto structure diagram. Furthermore, our method uses free-hand sketching techniques to allow users to create and edit 3D geometrical elements freely and easily. The final step is to automatically merge all independent 3D geometrical elements into a single waterproof mesh. Experiments show that this solid modeling approach is promising. Using our approach, novice users can create vivid flower models easily and freely. The generated flower model is waterproof. It can have applications in visu-alization, animation and toys and decorations if printed out on 3D rapid prototyping devices.

    2014-01-01

    Compared with the long history of auto/biography, biographical research in social sciences is fairly a recent thing.There has been a major turn towards biographical approaches in social science (especially in sociology)since the 1980s.Used by Chicago School in the 1920s-1930s,biographical sociology has been supplemented and enlarged ever since.It explores the interplay of biography,culture,and history,and represents the sociological imagination promoted by Wright Mills.The turn,generally speaking,is a reaction against the positivistic domination grounded in social research,emphasizing the role of individual subjectivity and human agency in social life. The turn tries to overcome a series of dualisms or dichotomies inherent in traditional sociological theories.It intends to guide sociologists to rethink about the conceptual framework,topics of enquiry,and also the procedures and practices at the heart of sociology and other social sciences.However,this emergent turn remains controversial. Pierre Bourdieu even denounces it as an illusion. Despite this, biographical sociology will claim a bigger place in academic research with the coming of so-called “the age of biography”.For its further growth,biographical sociology needs to develop its own framework,referring to classic sociological theories,and also to advance its capability of producing original knowledge about social structure and process from the study of individual life stories.%20世纪80年代前后,传记取向成为社会(科)学中众多转向或取向的一种。相较于20世纪二三十年代由芝加哥学派引领的传记研究,这一取向的范围更为宽广。它关注个人经历、历史与文化之间的交互作用,反对奉实证主义为圭臬的社会科学研究,重视人的主体性与能动性。这一取向消解或者说超越了传统的二元论或二分法,促使社会学家反思自己的概念架构、研究方法以及书写实践。虽然在晚近的发展

  4. Stories we teach by: intersections among faculty biography, student formation, and instructional processes.

    Science.gov (United States)

    Hooper, Barbara

    2008-01-01

    Becoming a professional who embodies certain dispositions is known as identity formation. Little research has explored what intentions educators hold for student identity formation or how such intentions influence their teaching. Nine faculty members (all female) in an occupation-centered curriculum were interviewed and observed over 8 weeks. Data were analyzed primarily through narrative writing and data matrixes. Ultimately, educators in this study taught who they were; each personified an implicit curriculum, which conveyed the kind of people students were to become and the ways of knowing they were to adopt through the culture, artifacts, rituals, and modes of communication within a program. In the formation of self-defining professionals who embody occupational therapy's ethos, equal attention is needed to the biographical experiences of faculty members, to thoughtful design of the implicit curriculum, and to the ways of knowing portrayed to students every day in the classroom.

    Full Text Available This critical sketch is dedicated to a new biography of Edward Stachura by Marian Buchowski. A writer like Stachura, whose work is very closely intertwined with his life (at least in his declarations is a challenging protagonist for a biography. In this article, attempts are made at following the way in which Buchowski tries to bring out another human being in the text. His ideas are juxtaposed and confronted with Stachura’s own life-and-art ideas, as to him looking for various methods of recording existence was among the crucial goals of writing. As a result, the thesis is put forward that some sort of a writer’s “totality” is a feature linking Stachura and Buchowski. In this context, the biography written by Buchowski is not only of importance to research into Stachura’s writing but also a significant countersignature of his work.

The question of the ways in which women contributed to Nazism and so to its crimes was suppressed after the Nazi defeat. On the basis of their gender, women were constructed as victims of the war and the hardships of the post-war period. In Austria specifically, this victim construction was blended with a national victim discourse that depicted Austria as the first victim of Hitler’s Germany, so allowing the denial of Austrians’ participation in Nazi crimes. In this context, this article aims to show, through three reconstructed biographies how, with the help of victim constructions, the biographical subjects extenuate and deny their own involvement in the Nazi society, in so doing positioning women’s activity as exterior to the practice of a perpetrator group constructed as male

    This paper presents a novel method for interpreting online multi-stroke sketching with straight lines. The multi-strokes are interpreted as sketch content and are used to generate 2D geometric primitives. The pretreatment approach proposed is able to interpret the dashed or continuous strokes. Through between two strokes fitting line position relations, it is proposed to estimate which is the multi-stroke sketching, and gives the multi-stroke fitting line method using itself characteristic. The distinguish method is proposed for start or terminal points of the multi-stroke sketching. The integrated definitions of straight line are given. This paper develops a human-computer interface prototype system FSR using the proposed theory, which makes system interface easy and friendly to user. The FRS sys-. Tem has been tested with a number of multi-stroke sketches, and the test results show that the algorithm achieves a satisfactory interpretative efficiency.%综合考虑笔划的时空关系对在线多笔划手绘直线段进行识别.基于时间关系进行多笔划预处理;详细讨论基于空间关系的多笔划绘制直线段的识别方法.提出利用两条笔划拟合直线段间的位置关系进行多笔划判定的方法;提出依据其原有拟合特征的多笔划直线段拟合方法及相应的首尾点确定方法;并给出带线型直线段的完整定义.通过算例对提出的算法加以验证和应用.

    Stellar Formation brings together knowledge about the formation of stars. In seeking to determine the conditions necessary for star formation, this book examines questions such as how, where, and why stars form, and at what rate and with what properties. This text also considers whether the formation of a star is an accident or an integral part of the physical properties of matter. This book consists of 13 chapters divided into two sections and begins with an overview of theories that explain star formation as well as the state of knowledge of star formation in comparison to stellar structure

Meanwhile, the observation and expression characteristics of sketches and comics and the improvement of curricular training are discussed. Comics and traditional easel paintings are different from each other. However, they share something in common as well. The timeliness and epidemicity of comics determine their social function as commercial circulation. Hence, reasonable and beautiful frames have become the main needs. This means that the preliminary training of comics is similar to that of easel paintings. The only difference is, comics emphasize more on a quick-understanding expression, so that they can meet the fast-paced business needs, while easel paintings are comparatively a personal creation type, they require a long-term research that can gather rich experience as well as a quick expression.

    Full Text Available For policy making and spatial planning, information is needed about the impacts of climate change on natural ecosystems. To provide this information, commonly hydrological and ecological models are used. We give arguments for our assessment that modelling only is insufficient for determining the impacts of climate changes on natural ecosystems at regional scales. Instead, we proposed a combination of hydrological simulations, a literature review and process-knowledge on climate-hydrology-vegetation interactions, to compile a sketch-map that indicates climate change effects on a number of ecosystems in The Netherlands. Soon after its introduction, copies of our sketch-map appeared in policy documents and in a commercial and popular atlas of The Netherlands. Moreover, the map led to a question in the Dutch parliament about the survivability of bog reserves in the future climate. Apparently, there was an urgent need for the information provided by the map.

    The map shows that climate change will presumably have the largest influence on ecosystems in The Netherlands that depend on precipitation as the major water source, like heathlands, dry grasslands, rain-fed moorland pools and raised bogs. Also highly susceptible are fens in reserves surrounded by deeply drained polders, because such fens depend on the inlet of surface water, of which quality is likely to deteriorate upon climate change. While the map is indicative for directions of change, in view of the uncertainties of our study no conclusions should be drawn that may have far-reaching consequences, such as giving up certain nature targets that might no longer be feasible in the future climate. Instead, we advise to anticipate on the potential threats from climate change by taking a number of adaptation measures that enhance the robustness of nature reserves.

  18. Towards an auditory account of speech rhythm: application of a model of the auditory 'primal sketch' to two multi-language corpora.

    2004-10-01

    The world's languages display important differences in their rhythmic organization; most particularly, different languages seem to privilege different phonological units (mora, syllable, or stress foot) as their basic rhythmic unit. There is now considerable evidence that such differences have important consequences for crucial aspects of language acquisition and processing. Several questions remain, however, as to what exactly characterizes the rhythmic differences, how they are manifested at an auditory/acoustic level and how listeners, whether adult native speakers or young infants, process rhythmic information. In this paper it is proposed that the crucial determinant of rhythmic organization is the variability in the auditory prominence of phonetic events. In order to test this auditory prominence hypothesis, an auditory model is run on two multi-language data-sets, the first consisting of matched pairs of English and French sentences, and the second consisting of French, Italian, English and Dutch sentences. The model is based on a theory of the auditory primal sketch, and generates a primitive representation of an acoustic signal (the rhythmogram) which yields a crude segmentation of the speech signal and assigns prominence values to the obtained sequence of events. Its performance is compared with that of several recently proposed phonetic measures of vocalic and consonantal variability.

    CERN Document Server

    Combes, F

    1999-01-01

    The currently discussed theories of bulge formation are reviewed, including the primordial scenario, where bulges form rapidly and then accrete disks, the secular scenario, where bulges are formed by dynamical evolution of disks through bars and galaxy interactions, and some combinations of both, where formation of bulges and disks are more continuous and interleaved. The various scenarios make specific predictions about the relative masses, angular momenta, colours, metallicities of bulges relative to disks, and the bulge-to-disk ratio as a function of time. Dynamical processes relevant to the formation of bulges (bar instabilities, mergers) are described and tested against observed statistics. Current data suggest a dynamical feedback from gravitational instabilities in bulge and disk formation. It is very difficult to discriminate between the various scenarios from surveys at z=0 only, and observations at high redshift are presently the best hope for large progress.

    Conductive-atomic force microscope (c-AFM) lithography at the LaAlO3/SrTiO3 interface has enabled the creation of various classes of nanostructures, such as nanoscale transistors, single-electron transistors and has proven to be a promising testbed for mesoscopic physics. To date, these devices have used lithographically-defined side gates, which are limited by leakage currents. To reduce leakage and improve the electric field effect, we have investigated nanostructures with in-situ grown gold top gate. We will discuss designs of logic devices such as inverters, NAND, and NOR gates. In the quantum regime, we compare the performance of in-situ vertical top gates and that of written coplanar side gates with Quantum Dot devices.

    To understand the meaning of the term Systems Medicine and to distinguish it from seemingly related other expressions currently in use, such as precision, personalized, -omics, or big data medicine, its underlying history and development into present time needs to be highlighted. Having this development in mind, it becomes evident that Systems Medicine is a genuine concept as well as a novel way of tackling the manifold complexity that occurs in nowadays clinical medicine-and not just a rebranding of what has previously been done in the past. So looking back it seems clear to many in the field that Systems Medicine has its origin in an integrative method to unravel biocomplexity, namely, Systems Biology. Here scientist by now gained useful experience that is on the verge toward implementation in clinical research and practice.Systems Medicine and Systems Biology have the same underlying theoretical principle in systems-based thinking-a methodology to understand complexity that can be traced back to ancient Greece. During the last decade, however, and due to a rapid methodological development in the life sciences and computing/IT technologies, Systems Biology has evolved from a scientific concept into an independent discipline most competent to tackle key questions of biocomplexity-with the potential to transform medicine and how it will be practiced in the future. To understand this process in more detail, the following section will thus give a short summary of the foundation of systems-based thinking and the different developmental stages including systems theory, the development of modern Systems Biology, and its transition into clinical practice. These are the components to pave the way toward Systems Medicine. PMID:26677176

    Theoretical models of star formation are discussed beginning with the earliest stages and ending in the formation of rotating, self-gravitating disks or rings. First a model of the implosion of very diffuse gas clouds is presented which relies upon a shock at the edge of a galactic spiral arm to drive the implosion. Second, models are presented for the formation of a second generation of massive stars in such a cloud once a first generation has formed. These models rely on the ionizing radiation from massive stars or on the supernova shocks produced when these stars explode. Finally, calculations of the gravitational collapse of rotating clouds are discussed with special focus on the question of whether rotating disks or rings are the result of such a collapse. 65 references.

    To simulate lines and shades in sketch style better, this paper presented an improved technique for rendering 3D meshes in the pencil drawing style. The algorithm divided the rendering process into three processes - contour drawing, texture drawing and tone adjustment. For contour drawing, this paper used multi-sampling to detect object contours and proposed chi-square distribution and trigonometric function to imitate the pencil line drawing. For texture drawing, this paper used the tangent and binormal of the model to generate integration directions. Then a pencil drawing texture was generated by using Liner Integral Convolution ( LIC) technology. As the result of the blend of multiple rendering may lead the tone to gray, this paper added the tone drawing before the final output. Through the Newton interpolation method to calculate the output curve, the final color distribution results were more like pencil drawing style. Experiments show that the work is more efficient and has a better performance. This algorithm can better simulate the hand-painted style lines and be applied to video game rendering.%为了更好地模拟素描画中线条的轻重变化和明暗变化,提出了一种改进的素描风格渲染算法。将渲染过程分为轮廓线绘制、纹理绘制和色调调整三个部分;在轮廓线染绘制过程中采用多重采样来辨识轮廓线,利用卡方分布和紊乱场来模拟生成素描化线条绘制;在纹理渲染绘制中,利用模型的切线和副法线生成多个方向场,通过对白噪声纹理的线性卷积( LIC)生成素描化纹理;通过牛顿插值法重新计算了输出曲线解决多重渲染混合后绘制效果偏灰问题。实验结果显示改进后素描风格渲染算法具有更高的渲染效率和更好的渲染效果。算法能够较好地实现素描风格的渲染效果,并可广泛适用于影视游戏开发中。

  20. On the Source of the Quotation from a «Biographer» of st. Sergius of Radonezh in prince E. N. Trubetskoy’s Lecture «Speculation in Colours»

    2014-12-01

    Full Text Available In his lecture «Speculation in Colours» prince E. N. Trubetskoy quotes an unnamed «biographer» of St. Sergius of Radonezh, who reported that the saint «erected a church in the name of the Holy Trinity as a mirror for all those whom he had gathered for communal life, so that the contemplation of the Holy Trinity might vanquish the fear of the hateful dividedness of the world». It is however noteworthy, that detecting the source of this quotation has not been possible up to this day: in fact, none of the ancient Vitae of St. Sergius contains it. Besides, although we can say with certainty that it was St. Sergius who has initiated special veneration of the Holy Trinity in the Russian tradition, an analysis of text sources shows that the idea of unification of the whole creation on the model of the Trinitarian unity — that exactly idea which was elaborated by prince E. N. Trubetskoy on the basis of the passage cited — is not presented in them. This makes the author of this article believe that the source for this quotation belongs to a much later epoch. His research let him claim that the source of the quotation is a text by archimandrite Anthony (Khrapovitsky which was interpolated by N. F. Fedorov into his own discourse and reproduced by prince Trubetskoy in Fedorov’s «transcription». This conclusion enables us to make our apprehensions about the Old Russian tradition more precise and to assess critically the concepts of modern theologians, philosophers and art scholars based on this quotation.

  1. The Patient’s Pain in Her Own Words: Margaret Mathewson’s ‘Sketch of Eight Months a Patient, in the Royal Infirmary of Edinburgh, A.D. 1877’

    Full Text Available It has been commonly assumed that nineteenth-century hospital patients were objectified, silenced, treated as the 'accident' of their disease, to use Michel Foucault's term, and also that as charity patients they were largely illiterate paupers, and consequently did not write accounts of their hospital experience. One such account has been known, however, since the 1970s, when W. B. Howie and S. A. B. Black published two articles in medical journals on Margaret Mathewson's 'Sketch of Eight Months a Patient, in the Royal Infirmary of Edinburgh, A.D. 1877'. Martin Goldman subsequently published excerpts from the 'Sketch' in 'Lister Ward' (1987. But Mathewson's account of her experience as a surgical patient of Joseph Lister has never been published in its entirety, nor has it been known that the two existing copies of the manuscript differ extensively, as Mathewson decided to leave out 'some insignificant items and put in others more interesting' in the later version. Admitted because Lister thought he could save her arm from amputation by excision of her tuberculous shoulder joint, her narrative vividly details what it was like to be a surgical patient in Scotland in 1877. Her revisions to that narrative provide clues as to what she thought prudent to exclude from her account, after friends had asked her to publish it. As a charity patient, she was subordinated to the hospital staff, expected to wait uncomplainingly and to accept whatever treatment was given. But her 'Sketch' reveals such unexpected and surprising information as the willingness of the staff, including Lister himself, to teach her and other patients about the nature of their disease and also how to care for themselves, especially how to change their own dressings. Even more startling, Mathewson's narrative documents her confrontation of a 'cruel dresser', a medical student whom she believed to be deliberately causing her pain when he changed her dressing and manipulated her arm

    幽默广泛地存在于人们的日常生活中。语言,面部表情,身体移动等多种形式都能制造幽默。但最常见的的表现形式则是言语幽默。喜剧小品就是一种借助语言表达幽默的艺术形式。许多语言学家从关联理论、言语行为理论等视角研究过小品中的言语幽默,但是以语用预设为理论框架的研究相对较少。文章运用孙茂玲在《近十年语用预设研究综述》中归纳的语用预设的基本特征为理论框架,从共知性、合适性、主观性和单向性四个方面对小品“今天的幸福”中的言语幽默进行研究,发现语用预设可以对中国喜剧小品中的幽默发挥重要作用。%Humor universally exists in people's daily life. Humor can be produced via language, facial expressions, body move-ments, etc, but the most common form is verbal humor. The comedy sketch is a kind of art form which expresses the humor with the help of a language. Many linguists study the verbal humor in comedy sketch from the views of relevance theory, speech act theory, etc, but less based on the theoretical framework of pragmatic presupposition. This paper used the characteristics of pragmatic presupposition summarized by Sun Maoling in A General Survey on the Pragmatic Presupposition as the theoretical framework. This paper anal sized the verbal humor in Chinese comedy sketch Jin tian de xing fu from the perspectives of com-mon ground, appropriateness, subjectivity and monotones. The discovery indicates that pragmatic presupposition plays an impor-tant role in the humor and amusement of comedy sketch.

    Full Text Available A novel gains value by means of the harmony among itscomponents. In this harmony, each component is equally important.However, ıt is important to analyze each component separately. In thisstudy, hero is handled as one of these components. A hero in a novel is a component that has undertaken the dramatic action and the thematic power. The hero is also handled from identity and personality point of view, and considered as the most essential instrument of reality impression. The presentation of the hero, therefore, is the main concern. The presentation of the hero is important. The author is completely free in selection and the regulation of the details that are used to shape the identity and personality of a hero. Biographic novels, in this sense, are hero centred narratives. However, they are supposed to combine the reality with the fiction to a certain degree as they are narratives partly resting on the reality. Bearing these in mind, the restricted use of fiction framed by the reality in biographic novels is an important issue, and it is worth questioning how it is used by different authors. This study aims to compare and contrast two biographic novels that narrates Yunus Emre by Emine Işınsu and İskender Pala. It further aims to investigate how identity and personality of Yunus shaped by these two authors. It is concluded that each narrative is some kind of interpretation.

    It is argued that within the standard Big Bang cosmological model the bulk of the mass of the luminous parts of the large galaxies likely had been assembled by redshift z approximately 10. Galaxy assembly this early would be difficult to fit in the widely discussed adiabatic cold dark matter model for structure formation, but it could agree with an isocurvature version in which the cold dark matter is the remnant of a massive scalar field frozen (or squeezed) from quantum fluctuations during inflation. The squeezed field fluctuations would be Gaussian with zero mean, and the distribution of the field mass therefore would be the square of a random Gaussian process. This offers a possibly interesting new direction for the numerical exploration of models for cosmic structure formation.

  5. The taphonomy of dinosaurs from the Upper Jurassic of Tendaguru (Tanzania based on field sketches of the German tendaguru expedition (1909–1913

    Full Text Available Tendaguru is one of the most important dinosaur localities in Africa. The Tendaguru Beds have produced a diverse Late Jurassic (Kimmeridgian to Tithonian dinosaur assemblage, including sauropods (Brachiosaurus, Barosaurus, Dicraeosaurus, Janenschia, theropods (e.g., Elaphrosaurus, Ceratosaurus, Allosaurus, and ornithischians (Kentrosaurus, Dryosaurus. Contrary to the well studied skeletal anatomy of the Tendaguru dinosaurs, the available taphonomic information is rather limited, and a generally accepted taphonomic model has not yet been established. Assessment of unpublished excavation sketches by the German Tendaguru expedition (1909–1913 document bone assemblages of sauropod and ornithischian dinosaurs from the Middle Saurian Bed, Upper Saurian Bed, and the Transitional Sands above the Trigonia smeei Bed, and shed some light on the taphonomy of the Tendaguru dinosaurs. Stages of disarticulation range from incomplete skeletons to solitary bones, and strongly argue for carcass decay and post-mortem transport prior to burial. The sauropod bone accumulations are dominated by adult individuals, and juveniles are rare or missing. The occurrence of bones in different superimposed dinosaur-bearing horizons indicates that skeletal remains were accumulated over a long time span during the Late Jurassic, and the majority of the bone accumulations are probably attritional. These accumulations are likely to have resulted from long-term bone imput due to normal mortality events caused by starvation, seasonal drought, disease, old age and weakness. The depositional environment of the Middle and Upper Saurian Bed was mainly limnic to brackish in origin, while the palaeoenvironment of the Transitional Sands was marginal marine. Tendaguru zählt zu den bedeutendsten Dinosaurier-Lagerstätten Afrikas. Aus den Tendaguru-Schichten sind zahlreiche Skelettreste von Sauropoden (Brachiosaurus, Barosaurus, Dicraeosaurus, Janenschia, Theropoden (z.B. Elaphrosaurus

    InkSurvey is free, web-based software designed to facilitate the collection of real-time formative assessment. Using this tool, the instructor can embed formative assessment in the instruction process by posing an open-format question. Students equipped with pen-enabled mobile devices (tablet PCs, iPads, Android devices including some smartphones) are then actively engaged in their learning as they use digital ink to draw, sketch, or graph their responses. When the instructor receives these responses instantaneously, it provides insights into student thinking and what the students do and do not know. Subsequent instruction can then repair and refine student understanding in a very timely manner. Although this pedagogical tool is appealing because of its broad theoretical foundations, the cost of pen-enabled mobile technology was until recently a significant barrier to widely implementing this teaching model. However, less expensive tablets, iPads, and Android devices are now filling the market (and student ba...

    The annual mean volume and heat transport sketches through the inter-basin passages and transoceanic sections have been constructed based on 1 400-year spin up results of the MOM4p1. The spin up starts from a state of rest, driven by the monthly climatological mean force from the NOAA World Ocean Atlas (1994). The volume transport sketch reveals the northward transport throughout the Pacific and southward trans-port at all latitudes in the Atlantic. The annual mean strength of the Pacific-Arctic-Atlantic through flow is 0.63×106 m3/s in the Bering Strait. The majority of the northward volume transport in the southern Pacific turns into the Indonesian through flow (ITF) and joins the Indian Ocean equatorial current, which subse-quently flows out southward from the Mozambique Channel, with its majority superimposed on the Ant-arctic Circumpolar Current (ACC). This anti-cyclonic circulation around Australia has a strength of 11×106 m3/s according to the model-produced result. The atmospheric fresh water transport, known as P-E+R (pre-cipitation minus evaporation plus runoff ), constructs a complement to the horizontal volume transport of the ocean. The annual mean heat transport sketch exhibits a northward heat transport in the Atlantic and poleward heat transport in the global ocean. The surface heat flux acts as a complement to the horizontal heat transport of the ocean. The climatological volume transports describe the most important features through the inter-basin passages and in the associated basins, including:the positive P-E+R in the Arctic substantially strengthening the East Greenland Current in summer;semiannual variability of the volume transport in the Drake Passage and the southern Atlantic-Indian Ocean passage;and annual transport vari-ability of the ITF intensifying in the boreal summer. The climatological heat transports show heat storage in July and heat deficit in January in the Arctic;heat storage in January and heat deficit in July in the

    As Chinese paintings of the 20th century have been influenced by western realistic paintings, the issue of sketching or painting from life has aroused great attention. This interview, while dealing with current Chinese paintings and sketches' emphasis on presenting authentic mountains and rivers, also touches upon the dilemma confronting current Chinese paintings--the lack of tradition and the lack of refining and sublimation in traditional brushes and inks. Chinese painting sketches should not only represent the authentic realities, but also turn these authentic experiences into expressions of inner feelings and emotions. The development of Chinese paintings should attend to both reality and traditional techniques. With the rapid development of economy, capital injection into art is also increasing, and capital is exerting a powerful influence on the development of art. The second issue of this interview mainly discusses the relationship between art market and artistic value and the influence of capital on artistic creation.%20世纪的中国画,由于受西方写实绘画的影响,写生的问题受到前所未有的重视。本访谈主要述及目前的中国画写生在强调对真山真水感受的同时,面临着缺少传统、缺少用传统的笔墨去提炼和升华写生的困境。中国画写生发展应在对真山真水的体验过程中,把体验转发为内心情感的表达,而不是现场真实性的再现,“一手伸向传统,一手伸向生活”,写实和传统技法要二者兼顾。由于经济的快速发展,资本对艺术的注入越来越多,资本的力量强劲地左右着艺术的发展,本访谈第二个问题主要阐述艺术市场与艺术价值的关系以及资本对艺术创作的影响。

  18. Formate Formation and Formate Conversion in Biological Fuels Production

    Directory of Open Access Journals (Sweden)

    Bryan R. Crable

    2011-01-01

    Full Text Available Biomethanation is a mature technology for fuel production. Fourth generation biofuels research will focus on sequestering CO2 and providing carbon-neutral or carbon-negative strategies to cope with dwindling fossil fuel supplies and environmental impact. Formate is an important intermediate in the methanogenic breakdown of complex organic material and serves as an important precursor for biological fuels production in the form of methane, hydrogen, and potentially methanol. Formate is produced by either CoA-dependent cleavage of pyruvate or enzymatic reduction of CO2 in an NADH- or ferredoxin-dependent manner. Formate is consumed through oxidation to CO2 and H2 or can be further reduced via the Wood-Ljungdahl pathway for carbon fixation or industrially for the production of methanol. Here, we review the enzymes involved in the interconversion of formate and discuss potential applications for biofuels production.

Among them, monarch images could be classified into four groups, namely ambitious, diligent, extravagant and romantic; while official image four groups, namely uninhibited, upright, reclusive and heroic; and the relationship between monarch and officials approximately into three groups, namely wise and harmonious, pleasure seeking and harmonious, and suspicious and strained. All these images with sameness or differences became the unique picture of Five Dynasties and Ten Kingdoms with frequent wars.

    The elegance of inflationary cosmology and cosmological perturbation theory ends with the formation of the first stars and galaxies, the initial sources of light that launched the phenomenologically rich process of cosmic reionization. Here we review the current understanding of early star formation, emphasizing unsolved problems and technical challenges. We begin with the first generation of stars to form after the Big Bang and trace how they influenced subsequent star formation. The onset of chemical enrichment coincided with a sharp increase in the overall physical complexity of star forming systems. Ab-initio computational treatments are just now entering the domain of the predictive and are establishing contact with local observations of the relics of this ancient epoch.

We cannot just resolve to learn. The whole reliable order can reach deadlock.. The old reliable knowledge and ability mismatchwhile we do not yet have any new possibility. Learning in this sense means a kind of “awakening”, in statu nascendi as the response to a challenge. Thus the condition of learning is sensitiveness to the other or to something, while it is possible via agreement that is not always disposed to us because of our peculiar attitudes. We always think more than we can express. Inevitably, we can do more than we anticipate. Only after the other takes this surplus the knowledge and the ability correspond to reality before they are realized. In learning we are met by another, to which we answer as to something.. This Something is always outstripping the meanings and aspirations. That is why this learning in true sense begins not in us. The destiny of every experience concerning us depends on this, while we cannot anticipate it exactly. Thus, the sense of in statu nascendi corresponds to the saying modo praeterito.

    First Academies originated in Italy at the beginnings of the Renaissance. Their works were of encyclopedic extent. Regarding to scientific academies, the first was the "Accademia dei Lincei" founded in Rome on August 17, 1603, due to the initiative of four young men; three naturalists and a physician. Later, several distiguished scientists were admitted, such as Giambattista della Porta, inventor of the dark chamber (1610) and Galileo Galilei (1611). This Academy sponsored the publication of a compendium of Francisco Hernández manuscripts, prepared by the Italian physician Antonio Nardo Recchi. Many years later, other scientific academies arose, such as the "Accademia del Cimento", established in 1657 in Florence and inspired by Galilean thought. In 1662, the "Royal Society" of London, was formally recognized, following Bacon's empirical line, and in 1666 the "Académie Royale des Sciences" was created in Paris, which followed the mechanicist orientation of Descartes. These scientific societies aspired to become centers of information and exchange ideas. Therefore, the "Philosophical Transactions" in London and the "Journal des Savants" in Paris began to be published in 1665. Both publications often included medical articles and notes. Regarding New Spain, the worthy "Academia médico-quirúrgica" of Puebla, mentioned since 1802, must be considered. In independent Mexico, two successive medical academies were established that paved the way for our National Academy of Medicine (1864). This society, since its birth, has been publishing the "Gaceta Médica de México", dean of the Mexican medical journals. PMID:12872422

    2014-05-01

    Full Text Available Professional development plays a demanding role in the continuous advancement of teachers. It does support all facets of academic careers, but accepting its importance to teaching is the most significant accountability of the organization and the teachers themselves. Professional faculty development bridges faculty across disciplines and career phases, serving to create a pedagogical community within the college or university. Professional development is not remedial or an activity only for those having concerns, but should be an essential component of every faculty member’s endeavor to become more effective in the classroom. It form teachers attentive of what they achieve, inquire them why and demand them to continually do it more excellent. Professional development enhances the affective, thoughtful and social aspects of academic life. It reforms the academic experience at institutions for teachers and students. Correctly designed faculty development approaches can promote and create a culture that supports a mindful focus on teaching, while concurrently, nourish a sense of association and collegiality across the organization that is crucial to constant innovation and progress. This study recommends a faculty professional development framework that can be designed to improve the collegial culture at a higher educational organization.

    The molecular gas content of local early-type galaxies is constrained and discussed in relation to their evolution. First, as part of the Atlas3D survey, we present the first complete, large (260 objects), volume-limited single-dish survey of CO in normal local early-type galaxies. We find a surprisingly high detection rate of 22%, independent of luminosity and at best weakly dependent on environment. Second, the extent of the molecular gas is constrained with CO synthesis imaging, and a variety of morphologies is revealed. The kinematics of the molecular gas and stars are often misaligned, implying an external gas origin in over a third of the systems, although this behaviour is drastically diffferent between field and cluster environments. Third, many objects appear to be in the process of forming regular kpc-size decoupled disks, and a star formation sequence can be sketched by piecing together multi-wavelength information on the molecular gas, current star formation, and young stars. Last, early-type gala...

    CERN Document Server

    Morbidelli, Alessandro

    2016-01-01

    Over the past two decades, large strides have been made in the field of planet formation. Yet fundamental questions remain. Here we review our state of understanding of five fundamental bottlenecks in planet formation. These are: 1) the structure and evolution of protoplanetary disks; 2) the growth of the first planetesimals; 3) orbital migration driven by interactions between proto-planets and gaseous disk; 4) the origin of the Solar System's orbital architecture; and 5) the relationship between observed super-Earths and our own terrestrial planets. Given our lack of understanding of these issues, even the most successful formation models remain on shaky ground.

    Watanabe,Shinsaku

    1982-12-01

    Full Text Available Paraquat is a broad spectrum herbicide known to be highly lethal to man and animals. Its toxicity is characterized by acute lung injury. Paraquat produces such toxic effects through the generation of the superoxide anion according to one proposed mechanism. The present experiment, methemoglobin formation was demonstrated after incubation of oxyhemoglobin with paraquat. The generation of the superoxide anion through the interaction of oxyhemoglobin with paraquat was suggested by chemiluminescence of luminol. Superoxide dismutase (SOD and catalare inhibited methemoglobin formation. The generation of the superoxide anion is discussed in regard to methemoglobin formation by paraquat.

  1. Formation of planetary systems

    Science.gov (United States)

    Lin, Douglas N. C.

    The discovery of extrasolar planets and the determination of their orbital properties have provided golden opportunities for new advancements in the quest to understand the origin and evolution of planets and planetary systems. While their bizarre variety presents a challenge for the existing theories, their ubiquity suggests that planetary formation is a robust process. Combining data obtained from solar system exploration, star formation studies and the searches for extra solar planets, we address some outstanding issues concerning critical processes of grain condensation, planetesimal coagulation, and gas accretion. Some implications of these investigations are: 1) the about of heavy elements available for planetary formation in protostellar disks is retained at a similar level as that empirically inferred for the primordial solar nebula, through self regulated processes and 2) the critical stages of planet formation, from grain condensation, planetesimal coagulation, to gas accretion, proceed on the timescale of a few million years.

    This book provides an introduction to the field of star formation at a level suitable for graduate students or advanced undergraduates in astronomy or physics. The structure of the book is as follows. The first two chapters begin with a discussion of observational techniques, and the basic phenomenology they reveal. The goal is to familiarize students with the basic techniques that will be used throughout, and to provide a common vocabulary for the rest of the book. The next five chapters provide a similar review of the basic physical processes that are important for star formation. Again, the goal is to provide a basis for what follows. The remaining chapters discuss star formation over a variety of scales, starting with the galactic scale and working down to the scales of individual stars and their disks. The book concludes with a brief discussion of the clearing of disks and the transition to planet formation. The book includes five problem sets, complete with solutions.

    Schild, Rudolph E

    2010-01-01

    Recent spacecraft observations exploring solar system properties impact standard paradigms of the formation of stars, planets and comets. We stress the unexpected cloud of microscopic dust resulting from the DEEP IMPACT mission, and the existence of molten nodules in STARDUST samples. And the theory of star formation does not explain the common occurrence of binary and multiple star systems in the standard gas fragmentation scenario. No current theory of planet formation can explain the iron core of the earth, under oceans of water. These difficulties are avoided in a scenario where the planet mass objects form primordially and are today the baryonic dark matter. They have been detected in quasar microlensing and anomalous quasar radio brightening bursts. The primordial planets often concentrate together to form a star, with residual matter seen in pre-stellar accretion discs around the youngest stars. These primordial planet mass bodies were formed of hydrogen-helium, aggregated in dense clumps of a trillion...

    In this review, three major changes in our understanding of the early history of the Solar System are presented. 1) Early differentiation: A few recent results support the idea that protoplanet formation and differentiation occurred partly simultaneously than CAI formation. First, some iron meteorites, eucrites, and angrites older than the chondrules or even than the CAI have been found. Second, iron meteorites could be debris of early disrupted differentiated planetesimals, scattered from the terrestrial planet region to the Main Belt. Finally, chondrules contain fragments of planetesimal material. 2) Earth and Moon: An equilibration mechanism explains the identical Oxygen isotopic composition of the Earth and the Moon. In addition, it has been shown that the Earth and the Moon mantles have the same 182^W anomaly, in contrast to what was believed before. Consequently, the Moon forming impact should have occurred after the extinction of the 182Hf radioactivity, about 60 Myr after Solar System formation. This ...

Biofilm cells were resistant to penicillin, but not to rifampin or ciprofloxacin. For some strains......, microcolony formation within biofilms was observed. Microcolony formation in strain MC58 depended on a functional copy of the pilE gene encoding the pilus subunit pilin, and was associated with twitching of cells. Nevertheless, unpiliated pilE mutants formed biofilms showing that attachment and accumulation......X alleles was identified among genetically diverse meningococcal strains.

  10. Formats and data storage

    International Nuclear Information System (INIS)

    The currently used ENDF-6 format has a number of shortcomings that originate from the punch-card legacy. Some, such as redundancy, counting lines, too short MAT number and too many options could be resolved within the current format. The more critical issues, such as rigidity to extensions, limited accuracy due to fixed number of digits, difficulty of reading by humans, lack of native software support, and lack of integration with EXFOR and ENSDF libraries, would require such considerable efforts that migration to a new and modern format, offering additional advantages, is a more attractive option. Actually, such an option is even more justified by the existence of the well advanced General Nuclear Data (GND) format being developed by LLNL. This XML based framework is easily extensible, its numerical precision is not fixed, it is easier to edit, can store additional information (e.g. renormalized experimental data used in the evaluation), allows for storing various versions side by side (e.g. reconstructed data, group-wise data, alternative evaluations), it may include hyperlinks to documentation or another set of data (e.g. covariances). Two additional advantages are the possibility of using native Python support software and already available conversion (in both directions) to the binary HDF5 format which allows to organize, store, access, analyze, share, and preserve data huge in both size and complexity. The GND format comes with the processing software FUDGE, whose class structure mirrors the GND format. It provides for arbitrary alteration of the data, energy deposition/kermas, data checking, translation to different format (ENDF-6, HDF5, ENDL), grouping, resonance reconstruction, visualization and sampling from covariances. It is deemed advantageous to the Nuclear Data community to adopt this new system and develop interfaces to the currently used processing codes and retrieval systems to take full advantage of the evolving technology. Such modernization is

  18. Generic file format

    Science.gov (United States)

    Felgate, Nick

    2002-11-01

    The Generic File Format (GFF) is a file format developed within the UK ASW community for the interchange and storage of underwater sonar data. Originally developed for the interchange of time-series data between analysis systems, it has been extended to provide for storage of processed acoustic data (e.g., power and DEMON spectrum, lofargram grey-scale), nonacoustic data (e.g., own-ship dynamics, sensor configuration) and event data (e.g., tracker output, sonar intercepts). The format employs the chunk concept, as used in the WAV and AIFF file formats, to provide extendability (including local variants) while providing a measure of backward compatability. However, the basic concept has been adapted to allow for the mixing in the one file of multiple channels of different sample-rates and data-types through the inclusion of a data frame concept and multiple data blocks. Chunk cross-referencing has been employed to ensure data consistency. A provision is made in the header of the file to store details of the sensor and processing for the data (e.g., the number of hydrophones, beam direction, FFT size) so that an analysis system does not need to know about the sensor or other system from which the data originated.

  20. Simulating Cosmic Structure Formation

    CERN Document Server

    Weinberg, D H; Hernquist, L E; Weinberg, David H.; Katz, Neal; Hernquist, Lars

    1997-01-01

    We describe cosmological simulation techniques and their application to studies of cosmic structure formation, with particular attention to recent hydrodynamic simulations of structure in the high redshift universe. Collisionless N-body simulations with Gaussian initial conditions produce a pattern of sheets, filaments, tunnels, and voids that resembles the observed large scale galaxy distribution. Simulations that incorporate gas dynamics and dissipation form dense clumps of cold gas with sizes and masses similar to the luminous parts of galaxies. Models based on inflation and cold dark matter predict a healthy population of high redshift galaxies, including systems with star formation rates of 20 M_{\\sun}/year at z=6. At z~3, most of the baryons in these models reside in the low density intergalactic medium, which produces fluctuating Lyman-alpha absorption in the spectra of background quasars. The physical description of this ``Lyman-alpha forest'' is particularly simple if the absorption spectrum is viewe...

  1. Emptiness Formation Probability

    Crawford, Nicholas; Ng, Stephen; Starr, Shannon

    2016-08-01

    We present rigorous upper and lower bounds on the emptiness formation probability for the ground state of a spin-1/2 Heisenberg XXZ quantum spin system. For a d-dimensional system we find a rate of decay of the order {exp(-c L^{d+1})} where L is the sidelength of the box in which we ask for the emptiness formation event to occur. In the {d=1} case this confirms previous predictions made in the integrable systems community, though our bounds do not achieve the precision predicted by Bethe ansatz calculations. On the other hand, our bounds in the case {d ≥ 2} are new. The main tools we use are reflection positivity and a rigorous path integral expansion, which is a variation on those previously introduced by Toth, Aizenman-Nachtergaele and Ueltschi.

  2. Plasma formation in TBR

    International Nuclear Information System (INIS)

    In this work are presented and discussed results of the formation and equilibrium of the plasma current in TBR, a small tokamak, designed and contructed at the Instituto de Fisica of Universidade de Sao Paulo. The measured breakdown curves for H2, A and He are compared with the predictions of a simple model with reasonable agreement. The influence of stray magnetic fields in the plasma formation is investigated and conditions are chosen to facilitate the breakdown. The time profile of loop voltage and plasma current for shots with plasma equilibrium are shown. A comparison is made between experimental results and analytical-numerical model for tokamaks discharges with ohmic heating. Reasonable agreement is obtained when Z, effective atomic number, is assumed as a parameter. (Author)

  3. Induced galaxy formation

    CERN Document Server

    Dokuchaev, V; Rubin, S; Dokuchaev, Vyacheslav; Eroshenko, Yury; Rubin, Sergei

    2004-01-01

    We describe the model of protogalaxy formation around the cluster of primordial black holes with a minimum extension of standard cosmological model. Namely, it is supposed, that a mass fraction of the universe ~10^-3 is composed of the compact clusters of primordial (relict) black holes produced during the phase transitions in the early universe. These clusters are the centers of the dark matter (DM) condensations. As a result the protogalaxies with a mass 2x10^8Msun form at the redshift z=15. These induced protogalaxies contain the central black holes of mass ~10^5Msun and look like the dwarf spheroidal galaxies with a central density spike. Subsequent merging of the induced protogalaxies and ordinary DM haloes leads to the standard scenario of the large scale structure formation. Black holes merging gives the nowadays supermassive black holes and reproduces the observed correlations between their masses and velocity dispersions in the bulges.

    2013-01-01

    While most research in Social Network Analysis has focused on single networks, the availability of complex on-line data about individuals and their mutual heterogenous connections has recently determined a renewed interest in multi-layer network analysis. To the best of our knowledge, in this paper...... we introduce the first network formation model for multiple networks. Network formation models are among the most popular tools in traditional network studies, because of both their practical and theoretical impact. However, existing models are not sufficient to describe the generation of multiple...... networks. Our model, motivated by an empirical analysis of real multi-layered network data, is a conservative extension of single-network models and emphasizes the additional level of complexity that we experience when we move from a single- to a more complete and realistic multi-network context....

    The formation of frost in presence of salt (NaCl) crystal is experimentally investigated on a hydrophobic surface. It presents several remarkable features due to the interplay of salty-water saturation pressure evolution, initially lower than the saturation pressure of ice and water, and the percolating propagation of ice dendrites from defects throughout the supercooled water droplet pattern. In particular, it is remarkable that nucleation of supercooled water and/or ice is prevented around ...

  12. Formation of transient lamellipodia.

    Directory of Open Access Journals (Sweden)

    Juliane Zimmermann

    Full Text Available Cell motility driven by actin polymerization is pivotal to the development and survival of organisms and individual cells. Motile cells plated on flat substrates form membrane protrusions called lamellipodia. The protrusions repeatedly appear and retract in all directions. If a lamellipodium is stabilized and lasts for some time, it can take over the lead and determine the direction of cell motion. Protrusions traveling along the cell perimeter have also been observed. Their initiation is in some situations the effect of the dynamics of the pathway linking plasma membrane receptors to actin filament nucleation, e.g. in chemotaxis. However, lamellipodia are also formed in many cells incessantly during motion with a constant state of the signaling pathways upstream from nucleation promoting factors (NPFs, or spontaneously in resting cells. These observations strongly suggest protrusion formation can also be a consequence of the dynamics downstream from NPFs, with signaling setting the dynamic regime but not initiating the formation of individual protrusions. A quantitative mechanism for this kind of lamellipodium dynamics has not been suggested yet. Here, we present a model exhibiting excitable actin network dynamics. Individual lamellipodia form due to random supercritical filament nucleation events amplified by autocatalytic branching. They last for about 30 seconds to many minutes and are terminated by filament bundling, severing and capping. We show the relevance of the model mechanism for experimentally observed protrusion dynamics by reproducing in very good approximation the repetitive protrusion formation measured by Burnette et al. with respect to the velocities of leading edge protrusion and retrograde flow, oscillation amplitudes, periods and shape, as well as the phase relation between protrusion and retrograde flow. Our modeling results agree with the mechanism of actin bundle formation during lamellipodium retraction suggested by

  15. Galaxy Formation and Evolution

    Science.gov (United States)

    Nagamine, Kentaro; Reddy, Naveen; Daddi, Emanuele; Sargent, Mark T.

    2016-07-01

    In this chapter, we discuss the current status of observational and computational studies on galaxy formation and evolution. In particular, a joint analysis of star-formation rates (SFRs), stellar masses, and metallicities of galaxies throughout cosmic time can shed light on the processes by which galaxies build up their stellar mass and enrich the environment with heavy elements. Comparison of such observations and the results of numerical simulations can give us insights on the physical importance of various feedback effects by supernovae and active galactic nuclei. In Sect. 1, we first discuss the primary methods used to deduce the SFRs, stellar masses, and (primarily) gas-phase metallicities in high-redshift galaxies. Then, we show how these quantities are related to each other and evolve with time. In Sect. 2, we further examine the distribution of SFRs in galaxies following the `Main Sequence' paradigm. We show how the so-called `starbursts' display higher specific SFRs and SF efficiencies by an order of magnitude. We use this to devise a simple description of the evolution of the star-forming galaxy population since z ˜3 that can successfully reproduce some of the observed statistics in the infrared (IR) wavelength. We also discuss the properties of molecular gas. In Sect. 3, we highlight some of the recent studies of high-redshift galaxy formation using cosmological hydrodynamic simulations. We discuss the physical properties of simulated galaxies such as luminosity function and escape fraction of ionizing photons, which are important statistics for reionization of the Universe. In particular the escape fraction of ionizing photons has large uncertainties, and studying gamma-ray bursts (which is the main topic of this conference) can also set observational constraints on this uncertain physical parameter as well as cosmic star formation rate density.

The organism forms peculiar macrocysts in the enrichment culture. In its other characteristics, the organism is similar to Methanococcus mazei. However, it classified as Methanosarcina, biotype 3, due to the characteristic formation of multicellular pseudococci.

  20. Terrestrial planet formation.

    Science.gov (United States)

    Righter, K; O'Brien, D P

    2011-11-29

    Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets. This information helps to guide numerical models for the three stages of planet formation from dust to planetesimals (~10(6) y), followed by planetesimals to embryos (lunar to Mars-sized objects; few 10(6) y), and finally embryos to planets (10(7)-10(8) y). Defining the role of turbulence in the early nebula is a key to understanding the growth of solids larger than meter size. The initiation of runaway growth of embryos from planetesimals ultimately leads to the growth of large terrestrial planets via large impacts. Dynamical models can produce inner Solar System configurations that closely resemble our Solar System, especially when the orbital effects of large planets (Jupiter and Saturn) and damping mechanisms, such as gas drag, are included. Experimental studies of terrestrial planet interiors provide additional constraints on the conditions of differentiation and, therefore, origin. A more complete understanding of terrestrial planet formation might be possible via a combination of chemical and physical modeling, as well as obtaining samples and new geophysical data from other planets (Venus, Mars, or Mercury) and asteroids.

    In this paper we show a plausible mechanism that could lead to the formation of the Dark Lanes in Lunar Swirls, and the electromagnetic shielding of the lunar surface that results in the preservation of the white colour of the lunar regolith. We present the results of a fully self-consistent 2 and 3 dimensional particle-in-cell simulations of mini-magnetospheres that form above the lunar surface and show that they are consistent with the formation of `lunar swirls' such as the archetypal formation Reiner Gamma. The simulations show how the microphysics of the deflection/shielding of plasma operates from a kinetic-scale cavity, and show that this interaction leads to a footprint with sharp features that could be the mechanism behind the generation of `dark lanes'. The physics of mini-magnetospheres is described and shown to be controlled by space-charge fields arising due to the magnetized electrons and unmagnetized ions. A comparison between model and observation is shown for a number of key plasma parameters...

The interpersonal optimism of people low in rejection sensitivity (RS), people who confidently expect acceptance rather than anxiously expect rejection, as do their high RS counterparts, suggests that they may strategically underestimate social threat cues when inferring the impression they have made on others. To test this hypothesis, participants viewed the videotaped reactions of individuals said to have read the participant's own or someone else's biographical sketch in an online dating context, and then estimated the emotions of the targets. Estimates of negativity were unrelated to RS when participants believed the videos captured the reactions to someone else's biographical sketch. However, to the extent that participants were low in RS, they made lower estimates of negativity when they believed the videos showed reactions to their biographical sketch compared to when they believed the videos captured the reactions to someone else's biographical sketch. The tracking accuracy of participants estimating negativity was unrelated to RS under either condition, but increased with trait empathy. RS was unrelated to estimates of positivity. Supporting functional perspectives on interpersonal perception, results show that interpersonal optimism shapes impressions of others' reactions to the self in ways that can foster relationship initiation.

    2012-12-01

    Full Text Available The Bouyei language is divided into three vernaculars, the southern vernacular, the central vernacular and the southwestern vernacular. This paper aims to describe the lexicology of the southern vernacular of the Bouyei language focusing on word formation process. Bouyei words are formed by affixing, compounding and reduplicating. First, the affixation consists of prefixing and suffixing. Infixing is not found in this language. Second, the compound is divided into the semantic and syntactic compound. Finally, the reduplication is divided into the simple and complex reduplication. The simple reduplication is normally used to emphasize the meaning of the root or to indicate plurality.

    A new model to simulate the time evolution of river delta formation process is presented. It is based on the continuity equation for water and sediment flow and a phenomenological sedimentation/ erosion law. Different delta types are reproduced using different parameters and erosion rules. The structures of the calculated patterns are analyzed in space and time and compared with real data patterns. Furthermore our model is capable to simulate the rich dynamics related to the switching of the mouth of the river delta. The simulation results are then compared with geological records for the Mississippi river.

    2014-01-01

    We examine the star formation histories (SFHs) of galaxies in smoothed particle hydrodynamics (SPH) simulations, compare them to parametric models that are commonly used in fitting observed galaxy spectral energy distributions, and examine the efficacy of these parametric models as practical tools for recovering the physical parameters of galaxies. The commonly used tau-model, with SFR ~ exp(-t/tau), provides a poor match to the SFH of our SPH galaxies, with a mismatch between early and late star formation that leads to systematic errors in predicting colours and stellar mass-to-light ratios. A one-parameter lin-exp model, with SFR ~ t*exp(-t/tau), is much more successful on average, but it fails to match the late-time behavior of the bluest, most actively star-forming galaxies and the passive, "red and dead" galaxies. We introduce a 4-parameter model, which transitions from lin-exp to a linear ramp after a transition time, which describes our simulated galaxies very well. We test the ability of these paramet...

  15. Formation of planetary systems

    International Nuclear Information System (INIS)

    It seemed appropriate to devote the 1980 School to the origin of the solar system and more particularly to the formation of planetary systems (dynamic accretion processes, small bodies, planetary rings, etc...) and to the physics and chemistry of planetary interiors, surface and atmospheres (physical and chemical constraints associated with their formation). This Summer School enabled both young researchers and hard-nosed scientists, gathered together in idyllic surroundings, to hold numerous discussions, to lay the foundations for future cooperation, to acquire an excellent basic understanding, and to make many useful contacts. This volume reflects the lectures and presentations that were delivered in this Summer School setting. It is aimed at both advanced students and research workers wishing to specialize in planetology. Every effort has been made to give an overview of the basic knowledge required in order to gain a better understanding of the origin of the solar system. Each article has been revised by one or two referees whom I would like to thank for their assistance. Between the end of the School in August 1980 and the publication of this volume in 1982, the Voyager probes have returned a wealth of useful information. Some preliminary results have been included for completeness

    2014-04-01

    Among the most fascinating and hotly-debated areas in contemporary astrophysics are the means by which planetary systems are assembled from the large rotating disks of gas and dust which attend a stellar birth. Although important work is being done both in theory and observation, a full understanding of the physics of planet formation can only be achieved by opening observational windows able to directly witness the process in action. The key requirement is then to probe planet-forming systems at the natural spatial scales over which material is being assembled. By definition, this is the so-called Hill Sphere which delineates the region of influence of a gravitating body within its surrounding environment. The Planet Formation Imager project has crystallized around this challenging goal: to deliver resolved images of Hill-Sphere-sized structures within candidate planet-hosting disks in the nearest star-forming regions. In this contribution we outline the primary science case of PFI and discuss how PFI could significantly advance our understanding of the architecture and potential habitability of planetary systems. We present radiation-hydrodynamics simulations from which we derive preliminary specifications that guide the design of the facility. Finally, we give an overview about the interferometric and non-interferometric technologies that we are investigating in order to meet the specifications.

    Protein disulfide isomerase, ERp5 and ERp57, among perhaps other thiol isomerases, are important for the initiation of thrombus formation. Using the laser injury thrombosis model in mice to induce in vivo arterial thrombus formation, it was shown that thrombus formation is associated with PDI secretion by platelets, that inhibition of PDI blocked platelet thrombus formation and fibrin generation, and that endothelial cell activation leads to PDI secretion. Similar results using this and other...

  20. Cosmological Structure Formation

    CERN Document Server

    2015-01-01

    LCDM is remarkably successful in predicting the cosmic microwave background and large-scale structure, and LCDM parameters have been determined with only mild tensions between different types of observations. Hydrodynamical simulations starting from cosmological initial conditions are increasingly able to capture the complex interactions between dark matter and baryonic matter in galaxy formation. Simulations with relatively low resolution now succeed in describing the overall galaxy population. For example, the EAGLE simulation in volumes up to 100 cubic Mpc reproduces the observed local galaxy mass function nearly as well as semi-analytic models. It once seemed that galaxies are pretty smooth, that they generally grow in size as they evolve, and that they are a combination of disks and spheroids. But recent HST observations combined with high-resolution hydrodynamic simulations are showing that most star-forming galaxies are very clumpy; that galaxies often undergo compaction which reduces their radius and ...

  1. Synapse formation and remodeling

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Synapses are specialized structures that mediate information flow between neurons and target cells,and thus are the basis for neuronal system to execute various functions,including learning and memory.There are around 1011 neurons in the human brain,with each neuron receiving thousands of synaptic inputs,either excitatory or inhibitory.A synapse is an asymmetric structure that is composed of pre-synaptic axon terminals,synaptic cleft,and postsynaptic compartments.Synapse formation involves a number of cell adhesion molecules,extracellular factors,and intracellular signaling or structural proteins.After the establishment of synaptic connections,synapses undergo structural or functional changes,known as synaptic plasticity which is believed to be regulated by neuronal activity and a variety of secreted factors.This review summarizes recent progress in the field of synapse development,with particular emphasis on the work carried out in China during the past 10 years(1999-2009).

  2. Dislocation Formation in Alloys

    Minami, Akihiko; Onuki, Akira

    2006-05-01

    An interaction between dislocations and phase transitions is studied by a phase field model both in two and three dimensional systems. Our theory is a simple extension of the traditional linear elastic theory, and the elastic energy is a periodic function of local strains which is reflecting the periodicity of crystals. We find that the dislocations are spontaneously formed by quenching. Dislocations are formed from the interface of binary alloys, and slips are preferentially gliding into the soft metals. In three dimensional systems, formation of dislocations under applied strain is studied in two phase state. We find that the dislocation loops are created from the surface of hard metals. We also studied the phase separation above the coexisting temperature which is called as the Cottrell atmosphere. Clouds of metals cannot catch up with the motion of dislocations at highly strained state.

    . Gallstone incidence was assessed through repeated ultrasound examinations. Body mass index (BMI), blood pressure, self-rated health, lifestyle variables, blood lipids, and use of female sex hormones were measured at the baseline examination. Statistical analyses included logistic regression. Based...... on a prospective protocol, a systematic review of the literature was performed identifying all articles dealing with determinants of incident gallstones. Meta-analyses of comparable determinants were performed through fixed effect models. Results: Participants with no gallstones at baseline and with at least one...... associations were found for blood pressure, smoking, alcohol consumption, HDL cholesterol, or triglycerides in meta-analyses. Conclusions: Age, female sex, BMI, non-HDL cholesterol, and polyps are independent determinants for gallstone formation. Incident gallstones and the metabolic syndrome share common risk...

    We present a detailed study of the formation of the amniotic sac in the avian embryo, and a comparison with the crocodile amniotic sac. We show that the amniotic sac forms at a circular line of stiffness contrast, separating rings of cell domains. Cells align at this boundary, and this in turn orients and concentrates the tension forces. The tissue fold which forms the amniotic sac is locked exactly along this line due to the colocalization of the stiffness contrast and of the tensile force. In addition, the tensile force plays a regenerative role when the amniotic sac is cut. The fold forming the ventral side of the embryo displays the same characteristics. This work shows that amniote embryogenesis consists of a cascade of buckling events taking place at the boundaries between regions of differing mechanical properties. Hence, amniote embryogenesis relies on a simple and robust biomechanical scheme used repeatedly, and selected ancestrally. PMID:27627351

    2009-11-01

    Anyone who has ever used baking soda instead of baking powder when trying to make a cake knows a simple truth: ingredients matter. The same is true for planet formation. Planets are made from the materials that coalesce in a rotating disk around young stars - essentially the "leftovers" from when the stars themselves formed through the gravitational collapse of rotating clouds of gas and dust. The planet-making disk should therefore initially have the same gas-to-dust ratio as the interstellar medium: about 100 to 1, by mass. Similarly, it seems logical that the elemental composition of the disk should match that of the star, reflecting the initial conditions at that particular spot in the galaxy.

    2005-01-01

    Broad and diverse ranges of activities are conducted within and by organized groups of individuals, including political, economic and social activities. These activities have recently become a subject of intense interest in economics and game theory. Some of the topics investigated in this collection are models of networks of power and privilege, trade networks, co-authorship networks, buyer-seller networks with differentiated products, and networks of medical innovation and the adaptation of new information. Other topics are social norms on punctuality, clubs and the provision of club goods and public goods, research and development and collusive alliances among corporations, and international alliances and trading agreements. While relatively recent, the literature on game theoretic studies of group formation in economics is already vast. This volume provides an introduction to this important literature on game-theoretic treatments of situations with networks, clubs, and coalitions, including some applications.

    2013-01-01

    The formation of complex nonuniform phases of nuclear matter, known as nuclear pasta, is studied with molecular dynamics simulations containing 51200 nucleons. A phenomenological nuclear interaction is used that reproduces the saturation binding energy and density of nuclear matter. Systems are prepared at an initial density of 0.10fm$^{-3}$ and then the density is decreased by expanding the simulation volume at different rates to densities of 0.01 fm$^{-3}$ or less. An originally uniform system of nuclear matter is observed to form spherical bubbles ("swiss cheese"), hollow tubes, flat plates ("lasagna"), thin rods ("spaghetti") and, finally, nearly spherical nuclei with decreasing density. We explicitly observe nucleation mechanisms, with decreasing density, for these different pasta phase transitions. Topological quantities known as Minkowski functionals are obtained to characterize the pasta shapes. Different pasta shapes are observed depending on the expansion rate. This indicates non equilibrium effects...

    Full Text Available Chinese language is one of the typical isolated languages. It lacks morphological variation; part of speech has no morphological signs; the additional component of word formation is less; and the roots never change their forms. The major method of Chinese word formation is the combination of roots according to certain grammatical relations. Although the affix word formation is not part of mainstream Chinese word formation, affix-formation is still an integral part of the Chinese word-formation. Article used literature review, summarized the types and meanings of Chinese affixes. And meanwhile, article analyzed word formation function of Chinese Affixes and quasi-affixes. The Chinese quasi-affixes have stronger capabilities in forming new words, but development direction of Chinese quasi-affixes has to stand the test of time.

    Methane is an important greenhouse gas and energy resource generated dominantly by methanogens at low temperatures and through the breakdown of organic molecules at high temperatures. However, methane-formation temperatures in nature are often poorly constrained. We measured formation temperatures of thermogenic and biogenic methane using a "clumped isotope" technique. Thermogenic gases yield formation temperatures between 157° and 221°C, within the nominal gas window, and biogenic gases yield formation temperatures consistent with their comparatively lower-temperature formational environments (<50°C). In systems where gases have migrated and other proxies for gas-generation temperature yield ambiguous results, methane clumped-isotope temperatures distinguish among and allow for independent tests of possible gas-formation models.

    Full Text Available Este artigo tem como propósito reconstituir o sentido conferido por D. Luciano Mendes de Almeida (1930-2006, bispo-auxiliar de São Paulo e arcebispo de Mariana, secretário e presidente da CNBB além de vice-presidente do CELAM, à sua própria trajetória biográfica. Verifica-se que, se cotejada com balizas culturais contemporâneas, tal configuração de si porta contornos aparentemente paradoxais: ao invés de fortalecer uma identidade pessoal, ela pressupõe uma dinâmica antropológico-religiosa de autoesvaziamento, concomitante a uma atuação mediadora em prol de relações ternárias entre Deus, os sujeitos e si mesmo, processo denominado por D. Luciano como “interiorização da figura Jesus Cristo”. Com o suporte teórico provindo da semiótica e da história religiosa, tal interiorização é aqui compreendida como um programa narrativo específico, que adquiriu formas singulares ao longo dos séculos, com destaque à espiritualidade inaciana, mas preservando sua concepção como um agir, pela fé, em nome da competência atribuída a um Outro. Sugere-se ainda que, na atualidade, a interiorização possa ser aproximada do relato de testemunho, face ao engajamento ético por ela suscitado, que reconfigura o sujeito no compartilhar de experiências vividas e postas em discurso.

These clouds could host star clusters with the masses and sizes of real globular clusters. I describe current state-of-the-art simulations aimed at understanding the origin of the cluster mass function and metallicity distribution. Metallicity bimodality of globular cluster systems appears to be a natural outcome of hierarchical formation and gradually declining fraction of cold gas in galaxies. Globular cluster formation was most prominent at redshifts z>3, when massive star clusters may have contributed as much as 20% of all galactic star formation.

    During degradation of organic pollutants in soil, metabolites, microbial biomass, CO2and "bound" residues ("non-extractable" residues in soil organic matter) are formed. Enhanced transformation of these contaminants into "bound" residues has been proposed as an alternative remediation method for polluted soils. However, this kind of residues may pose a potential risk for the environment due to their chemical structure and possible remobilization under different conditions. Therefore particular attention is given actually to "bound" residues. Part of these non-extractable residues may be "biogenic," because microorganisms use the carbon from the pollutant to form their biomass components (fatty acids, amino acids, amino sugars), which subsequently may be incorporated into soil organic matter. Furthermore, the CO2 originating from mineralization of xenobiotics, can be re-assimilated by microorganisms and also incorporated into "biogenic residue". The hazard posed by "bound" residues may be overestimated because they are "biogenic" (contain microbial fatty acids and amino acids). The knowledge about the pathways of "biogenic residue" formation is necessary for a proper assessment of the fate of tested pollutants and their turnover in the soil environment. Moreover, these data are needed to establish the realistic degradation rates of the contaminants in soil. The main objectives of this study are: to quantify the extent of "biogenic residue" (fatty acids, amino acids, amino sugars) formation during the degradation of a model pollutant (2,4-dichlorophenoxyacetic acid = 2,4-D) and during CO2 assimilation by microorganisms and to evaluate which components are mainly incorporated into "bound" residues. To investigate the extent of "biogenic residue" formation in soil during the degradation of 2,4-D, experiments with either 14C-U-ring and 13C6-2,4-D or carboxyl-14C 2,4-D were performed. The incubation experiments were performed according to OECD test guideline 307, in the

    Objective To explore the mechanisms of differentiation and development of pancreatic endocrine cells as well as pancreatic regeneration. Methods Human embryonic pancreatic tissue at 7-14 weeks of gestation was collected. Diabetes mellitus rat model was induced with 65 mg/kg of streptozotocin. Insulin, glucagon, somatostatin, nestin, and cytokeratin 19 (CK19)of pancreatic tissues were observed by immunohistochemistry. Results At 9 weeks of gestation, pancreatic epithelial cells began to co-express insulin, glucagon, somatostatin, and CK19 before migration. Islet cells gradually congregated along with the increase of aging, and at 14 weeks of gestation histological examination showed islet formation. At 12 weeks of gestation, nestin-positive cells could be seen in the pancreatic mesenchyme. During early embryogenesis, islet cells of pancreatic ducts co-expressed insulin, glucagon, and somatostatin. During pancreatic regeneration after damage, nestin expression of islet cells increased. Conclusion In the early stage of embryogenesis, islet cells of primary pancreatic ducts can be differentiated to multipotential endocrine cells before migration. During tissue regeneration, pancreatic stem cells may differentiate and proliferate to form pancreatic islet.

    There are a large number of image formats already in use within the remote sensing community but currently there is no format that provides the features of: compression, support for large file sizes, ground control points, raster attribute tables and inbuilt image pyramids. Therefore, a new image format, named KEA, after the New Zealand bird, has been proposed. The KEA format provides a full implementation of the GDAL data model and is implemented within a HDF5 file. A software library with a GDAL driver have been freely provided to the community allowing use through any GDAL based software. The new format has comparable performance with existing formats while producing smaller file sizes and is already within active use for a number of projects within Landcare Research, New Zealand, and the wider community.

    The growth and composition of Earth is a direct consequence of planet formation throughout the Solar System. We discuss the known history of the Solar System, the proposed stages of growth and how the early stages of planet formation may be dominated by pebble growth processes. Pebbles are small bodies whose strong interactions with the nebula gas lead to remarkable new accretion mechanisms for the formation of planetesimals and the growth of planetary embryos. Many of the popular models for ...

    We present a study of droplet formation in a gas-liquid mixing layer using direct numerical simulation. It is seen that two mechanisms compete to generate the droplets: fingering at the tip of the waves and hole formation in the thin liquid sheet. The three dimensional liquid structures are much shorter than the longitudinal wavelength of the instability at the first instant of their formation. As time evolves, the structures evolves to larger and larger scales, in a way similar to the inverse cascade of length scales in droplet impact and impact crown formation.

    When a group of dense particles is released instantaneously into water, their motion has been conceptualized as a circulating particle thermal (Ruggerber 2000). However, Wen and Nacamuli (1996) observed the formation of particle clumps characterized by a narrow, fast moving core shedding particles into wakes. They observed the clump formation even for particles in the non-cohesive range as long as the source Rayleigh number was large (Ra > 1E3) or equivalently the source cloud number (Nc) was small (Nc < 3.2E2). This physical phenomenon has been investigated by Zhao et al. (2014) through physical experiments. They proposed the theoretical support for Nc dependence and categorized the formation processes into cloud formation, transitional regime and clump formation. Previous works focused mainly on the behavior of monodisperse particles. The present study further extends the experimental investigation to the formation process of bidisperse particles. Experiments are conducted in a glass tank with a water depth of 90 cm. Finite amounts of sediments with various weight proportions between coarser and finer particles are released from a cylindrical tube. The Nc being tested ranges from 6E-3 to 9.9E-2, which covers all the three formation regimes. The experimental results showed that the introduction of coarse particles promotes cloud formation and reduce the losses of finer particles into the wake. More quantitative descriptions of the effects of source conditions on the formation processes will be presented during the conference.

  2. The formation of Pangea

    2013-05-01

    The making of Pangea is the result of large-scale amalgamation of continents and micro-continents, which started at the end of the Neoproterozoic with the formation of Gondwana. As pieces were added to Gondwana on its South-American, Antarctica and Australia side, ribbon-like micro-continents were detached from its African and South-Chinese side: Cadomia in the late Neoproterozoic, Avalonia and Hunia in the Ordovician, Galatia in the Devonian and Cimmeria in the Permian. Cadomia was re-accreted to Gondwana, but the other ribbon-continents were accreted to Baltica, North-China, Laurussia or Laurasia. Finding the origin of these numerous terranes is a major geological challenge. Recently, a global plate tectonic model was developed together with a large geological/geodynamic database, at the Lausanne University, covering the last 600 Ma of the Earth's history. Special attention was given to the placing of Gondwana derived terranes in their original position, using all possible constraints. We propose here a solution for the Variscan terranes, another paper deals with the Altaids. The Galatian super-terrane was detached from Gondwana in the Devonian, during the opening of Paleotethys, and was quickly separated into four sub-terranes that started to by-pass each other. The leading terranes collided at the end of the Devonian with the Hanseatic terrane detached from Laurussia. In the Carboniferous, Gondwana started to impinge onto the amalgamated terranes, creating the Variscan chain and the Pangean super-continent. East of Spain Paleotethys remained opened until the Triassic, subducting northward under Laurasia. Roll-back of the Paleotethyan slab triggered the collapse of most of the European Variscan orogen, which was replaced by series of Permian rifts, some of them becoming oceanized back-arc basins during the Triassic. Major force changes at the Pangean plate limits at the end of the Triassic provoked its break-up, through the opening of the proto

    Full Text Available This article aims at presenting a state of the art status of formative assessment as a pedagogic tool. To this end, a brief developmental account of different modes of assessment over the last decades will be presented first. Then, formative assessment will be discussed in its constructivist guise. The present literature on assessment suggests that assessment for learning (formative assessment not only represents an assessment tool but it also serves as a pedagogic tool to enhance learning and thinking. It has also gone to lengths to affect the design of classroom tasks and activities. Attempts have been made to delineate the underlying principles of formative assessment which can be used to picture the formation process of learners’ knowledge and development. Subsequently, alternative assessment techniques of which the present article will give an account have been suggested by scholars to operationalize these principles.

    The study of primordial star formation has a history of nearly sixty years. It is generally thought that primordial stars are one of the key elements in a broad range of topics in astronomy and cosmology, from Galactic chemical evolution to the formation of super-massive blackholes. We review recent progress in the theory of primordial star formation. The standard theory of cosmic structure formation posits that the present-day rich structure of the Universe developed through gravitational amplification of tiny matter density fluctuations left over from the Big Bang. It has become possible to study primordial star formation rigorously within the framework of the standard cosmological model. We first lay out the key physical processes in a primordial gas. Then, we introduce recent developments in computer simulations. Finally, we discuss prospects for future observations of the first generation of stars.

The main task of this paper is clearly to show processes of formation of spectral lines as well as their distinction by validity and by location. For 503 photospheric lines of various chemical elements in the wavelength range 300--1000 nm we list in Table the average formation depths of the line depression and the line emission for the line centre and on the half-width of the line, the average formation depths of the continuum emission as well as the effective widths of the layer of the line depression formation. Dependence of average depths of line depression formation on excitation potential, equivalent widths, and central line depth are demonstrated by iron lines.

However, many disadvantages such as slow mapping speed, poor mapping precision, difficulty in modification and management are caused subsequently. So the old method using manual mapping and processing can not meet the need of modernization. A new system implementing automatic mapping based on ArcGIS Engine is proposed, and the main architecture and basic function of this system are introduced.

    Kuhlen, M; Madau, P; Smith, B; Wise, J

    2011-01-01

    We describe cosmological galaxy formation simulations with the adaptive mesh refinement code Enzo that incorporate a star formation prescription regulated by the local abundance of molecular hydrogen. We show that this H2-regulated prescription leads to a suppression of star formation in low mass halos (M_h 4, alleviating some of the dwarf galaxy problems faced by theoretical galaxy formation models. H2 regulation modifies the efficiency of star formation of cold gas directly, rather than indirectly reducing the cold gas content with "supernova feedback". We determine the local H2 abundance in our most refined grid cells (76 proper parsec in size at z=4) by applying the model of Krumholz, McKee, & Tumlinson, which is based on idealized 1D radiative transfer calculations of H2 formation-dissociation balance in ~100 pc atomic--molecular complexes. Our H2-regulated simulations are able to reproduce the empirical (albeit lower z) Kennicutt-Schmidt relation, including the low Sigma_gas cutoff due to the transi...

  16. Portfolio Optimization under Habit Formation

    CERN Document Server

    Naryshkin, Roman

    2008-01-01

    The "standard" Merton formulation of optimal investment and consumption involves optimizing the integrated lifetime utility of consumption, suitably discounted, together with the discounted future bequest. In this formulation the utility of consumption at any given time depends only on the amount consumed at that time. However, it is both theoretically and empirically reasonable that an individuals utility of consumption would depend on past consumption history. Economists term this "Habit Formation". We introduce a new formulation of habit formation which allows non-addictive consumption patterns for a wide variety of utility specification. In this paper we construct a simple mathematical description of this habit formation and present numerical solutions. We compare the results with the standard ones and draw insights obtained from the habit formation. The consumption path tends to increase with time and be less sensitive to the market fluctuations, which perfectly reflects the existence of habit persistenc...

    2014-01-01

    Accumulation of dust and ice particles into planetesimals is an important step in the planet formation process. Planetesimals are the seeds of both terrestrial planets and the solid cores of gas and ice giants forming by core accretion. Left-over planetesimals in the form of asteroids, trans-Neptunian objects and comets provide a unique record of the physical conditions in the solar nebula. Debris from planetesimal collisions around other stars signposts that the planetesimal formation process, and hence planet formation, is ubiquitous in the Galaxy. The planetesimal formation stage extends from micrometer-sized dust and ice to bodies which can undergo run-away accretion. The latter ranges in size from 1 km to 1000 km, dependent on the planetesimal eccentricity excited by turbulent gas density fluctuations. Particles face many barriers during this growth, arising mainly from inefficient sticking, fragmentation and radial drift. Two promising growth pathways are mass transfer, where small aggregates transfer u...

    Full Text Available Motivated by the idea of multiplexed model predictive control (MMPC, this paper introduces a new framework for unmanned aerial vehicles (UAVs formation flight and coordination. Formulated using MMPC approach, the whole centralized formation flight system is considered as a linear periodic system with control inputs of each UAV subsystem as its periodic inputs. Divided into decentralized subsystems, the whole formation flight system is guaranteed stable if proper terminal cost and terminal constraints are added to each decentralized MPC formulation of the UAV subsystem. The decentralized robust MPC formulation for each UAV subsystem with bounded input disturbances and model uncertainties is also presented. Furthermore, an obstacle avoidance control scheme for any shape and size of obstacles, including the nonapriorily known ones, is integrated under the unified MPC framework. The results from simulations demonstrate that the proposed framework can successfully achieve robust collision-free formation flights.

  1. EPR dosimetric properties of formates

    International Nuclear Information System (INIS)

    As a part of a program to develop an electron paramagnetic resonance (EPR) dosimeter suited for clinical use (doses in the cGy range), polycrystalline samples of lithium formate monohydrate (HCO2Li·H2O), magnesium formate dihydrate (C2H2O4Mg·2H2O), and calcium formate (C2H2O4Ca) have been examined. L-Alanine was included for comparison and reference. Samples were irradiated with 60Co γ-rays and 60-220 kV X-rays. The dosimeter response was assessed using the peak-to-peak amplitude of the first-derivative EPR spectrum. Dose-response curves for the 60Co γ-irradiated samples were constructed, and the dependences of the response on the photon energy, microwave power, and modulation amplitude were studied. Stability of the irradiation products upon storage (signal fading) was also investigated. Lithium formate monohydrate is by far the best candidate of the tested formates, suitable for measuring doses down to approximately 0.1 Gy. Lithium formate monohydrate is more sensitive than alanine by a factor of 5.6-6.8 in the tested photon energy range, it exhibits no zero-dose signal and shows a linear dose response in the dose range from 0.2 to 1000 Gy. Its EPR signal was found unchanged in shape and intensity 1 week after irradiation to 10 Gy. Various less favorable properties rendered the other formates generally unsuitable, although calcium formate exhibits some interesting EPR dosimetric properties

    During the mineralisation of metal carbonates MCO3 (M = Ca, Sr, Ba, Mn, Cd, Pb) liquid-like amorphous intermediates emerge. These intermediates that form via a liquid/liquid phase separation behave like a classical emulsion and are stabilized electrostatically. The occurrence of these intermediates is attributed to the formation of highly hydrated networks whose stability is mainly based on weak interactions and the variability of the metal-containing pre-critical clusters. Their existence and compositional freedom are evidenced by electrospray ionization mass spectrometry (ESI-MS). Liquid intermediates in non-classical crystallisation pathways seem to be more common than assumed.During the mineralisation of metal carbonates MCO3 (M = Ca, Sr, Ba, Mn, Cd, Pb) liquid-like amorphous intermediates emerge.

    "A Visit to the Hangchow Bore" in The Popular Science Monthly (1908) is one of Charles K. Edmunds' sketches written during his travels around China in early 20th century. It records in great details his observations of and reflections on what he saw along the canals between Shanghai and Haining, as well as the Hangchow Bore. Like other similar sketches by John Green and William R. Kahler during approximately the same period, it provides an objective reference to our understanding of the local culture in the regions of Jiaxing and Haining a century ago. Unfortunately these sketches were written either in English or in German, and in them there are many proper names and special terminology that need expli- cation. The present paper is an attempt in this direction.%美国传教士晏文士发表在《大众科学月刊》上的一篇海宁观潮连载文章,是他在中国各地旅行时细心观察和记录的成果之一。它详细记载了作者从上海至海宁的旅途见闻和在海宁观看钱江大潮的细节和感受。与同期的葛骆和葛利等其他两位外国人所写的钱江观潮游记一样,它为我们了解百年前的杭嘉湖地域文化提供了一个客观的参照。由于上述游记是用英文、德文等欧洲文字发表的,而且文章中有不少人名、地名和意思比较隐晦的专门术语,一般的读者难以看懂,需要有人对此加以翻译和解读。本文便是这样的一种尝试。

    A number of theoretical and simulation results on star and structure formation in galaxy interactions and mergers is reviewed, and recent hydrodynamic simulations are presented. The role of gravity torques and ISM turbulence in galaxy interactions, in addition to the tidal field, is highlighted. Interactions can drive gas inflows towards the central kpc and trigger a central starburst, the intensity and statistical properties of which are discussed. A kinematically decoupled core and a supermassive central black hole can be fueled. Outside of the central kpc, many structures can form inside tidal tails, collisional ring, bridges, including super star clusters and tidal dwarf galaxies. The formation of super star clusters in galaxy mergers can now be directly resolved in hydrodynamic simulations. Their formation mechanisms and long-term evolution are reviewed, and the connection with present-day early-type galaxies is discussed.

    Land tenure inequity is a major social problem in developing nations worldwide. In societies, where land is a commodity, inequities in land tenure are associated with gaps in income distribution, poverty and biodiversity loss. A common pattern of land tenure inequities through the history of civilization has been the formation of latifundia [Zhuāngyuán in chinese], i.e., a pattern where land ownership is concentrated by a small fraction of the whole population. Here, we use simple Markov chain models to study the dynamics of latifundia formation in a heterogeneous landscape where land can transition between forest, agriculture and recovering land. We systematically study the likelihood of latifundia formation under the assumption of pre-capitalist trade, where trade is based on the average utility of land parcels belonging to each individual landowner during a discrete time step. By restricting land trade to that under recovery, we found the likelihood of latifundia formation to increase with the size of the system, i.e., the amount of land and individuals in the society. We found that an increase of the transition rate for land use changes, i.e., how quickly land use changes, promotes more equitable patterns of land ownership. Disease introduction in the system, which reduced land profitability for infected individual landowners, promoted the formation of latifundia, with an increased likelihood for latifundia formation when there were heterogeneities in the susceptibility to infection. Finally, our model suggests that land ownership reforms need to guarantee an equitative distribution of land among individuals in a society to avoid the formation of latifundia. PMID:24376597

    It is clear that PAHs play an important role in PCDF formation. It does not matter if PCDF are formed from carbonaceous material or from PAH adsorbed on the carbon surface. The role of PAH in the formation of PCDF has been studied by several authors. Probably one of the most complete investigations was conducted by Wilhelm et al. They investigated PCDF formation from twelve different PAHs with structures similar to the PCDF. The results of this study showed that biphenyl-like structures can be easily converted to PCDFs. Although the biphenyl-like structures are clearly involved in PCDF formation, there are several aspects of this formation pathway that are not well understood. Iino et al. found that higher PCDF yields could be obtained from pyrene than phenanthrene, contradicting biphenyl intermediate formation pathway theory as phenantrene structure can more easily be converted to biphenyl than pyrene. All previous PCDD/F formation studies from PAHs were conducted using CuCl{sub 2} as model fly ash. CuCl{sub 2} is highly volatile and probably not present in any significant quantities in the actual fly ash. High temperature oxidative conditions in the high temperature zone are able to oxidize all transition metals to their oxides. Therefore, Cu in actual fly ash is most probably present as CuO or Cu2O. Also in previous studies, PAH - model fly ash mixtures were prepared at room temperature and then heated to experimental temperatures. This experimental method can lead to some uncertainties because depending on PAH boiling point, various amounts of different PAHS would have evaporated by the time experimental temperatures were achieved. The main objective of this study is to address all the above issues and develop a better understanding of the role of biphenyl structures in PCDF formation. The salient features of this study are: Use of CuO+HCl as model fly ash instead of CuCl{sub 2} which was traditionally used in earlier De Novo studies. Study major non

    We investigate the triggering of star formation in clouds that form in Galactic scale flows as the interstellar medium passes through spiral shocks. We use the Lagrangian nature of smoothed particle hydrodynamics simulations to trace how the star-forming gas is gathered into self-gravitating cores that collapse to form stars. Large-scale flows that arise due to Galactic dynamics create shocks of the order of 30 km s-1 that compress the gas and form dense clouds (n > several × 102 cm-3) in which self-gravity becomes relevant. These large-scale flows are necessary for creating the dense physical conditions for gravitational collapse and star formation. Local gravitational collapse requires densities in excess of n > 103 cm-3 which occur on size scales of ≈1 pc for low-mass star-forming regions (M 103 M⊙). Star formation in the 250 pc region lasts throughout the 5 Myr time-scale of the simulation with a star formation rate of ≈10-1 M⊙ yr-1 kpc-2. In the absence of feedback, the efficiency of the star formation per free-fall time varies from our assumed 100 per cent at our sink accretion radius to values of <10-3 at low densities.

  14. Resolving the Formation of Protogalaxies

    Cosmic structure originated from minute density perturbations in an almost homogeneous universe. The first stars are believed to be very massive and luminous, providing the first ionizing radiation and heavy elements to the universe and forming 100 million years after the Big Bang. The impact from primordial stellar radiation is far reaching and affects subsequent star and galaxy formation. In this thesis, we present results from adaptive mesh refinement calculations of the formation of the first galaxies. We gradually introduce important physical processes, such as molecular hydrogen cooling and stellar feedback, to base models that only consider atomic hydrogen and helium cooling. In these base models, we find that gas in dark matter halos with masses ~10^8 solar masses centrally collapse before multiple fragmentation occurs in a global disc. We then investigate the importance of molecular hydrogen cooling in early structure formation in the presence of a soft ultraviolet radiation background. We find that ...

    Galaxies are the basic unit of cosmology. The study of galaxy formation is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning. The physics of galaxy formation is complicated because it deals with the dynamics of stars, thermodynamics of gas and energy production of stars. A black hole is a massive object whose gravitational field is so intense that it prevents any form of matter or radiation to escape. It is hypothesized that the most massive galaxies in the universe- "elliptical galaxies"- grow simultaneously with the supermassive black holes at their centers, giving us much stronger evidence that black holes control galaxy formation. This book reviews new evidence in the field.

  16. Formation of porous gas hydrates

    Gas hydrates grown at gas-ice interfaces are examined by electron microscopy and found to have a submicron porous texture. Permeability of the intervening hydrate layers provides the connection between the two counterparts (gas and water molecules) of the clathration reaction and makes further hydrate formation possible. The study is focused on phenomenological description of principal stages and rate-limiting processes that control the kinetics of the porous gas hydrate crystal growth from ice powders. Although the detailed physical mechanisms involved in the porous hydrate formation still are not fully understood, the initial stage of hydrate film spreading over the ice surface should be distinguished from the subsequent stage which is presumably limited by the clathration reaction at the ice-hydrate interface and develops after the ice grain coating is finished. The model reveals a time dependence of the reaction degree essentially different from that when the rate-limiting step of the hydrate formation at...

  17. Spatial competition and price formation

    We look at price formation in a retail setting, that is, companies set prices, and consumers either accept prices or go someplace else. In contrast to most other models in this context, we use a two-dimensional spatial structure for information transmission, that is, consumers can only learn from nearest neighbors. Many aspects of this can be understood in terms of generalized evolutionary dynamics. In consequence, we first look at spatial competition and cluster formation without price. This leads to establishement size distributions, which we compare to reality. After some theoretical considerations, which at least heuristically explain our simulation results, we finally return to price formation, where we demonstrate that our simple model with nearly no organized planning or rationality on the part of any of the agents indeed leads to an economically plausible price.

    Bundling of single polymer chains is a crucial process in the formation of biopolymer network gels that make up the extracellular matrix and the cytoskeleton. This bundled architecture leads to gels with distinctive properties, including a large-pore-size gel formation at very low concentrations and mechanical responsiveness through nonlinear mechanics, properties that are rarely observed in synthetic hydrogels. Using small-angle X-ray scattering (SAXS), we study the bundle formation and hydrogelation process of polyisocyanide gels, a synthetic material that uniquely mimics the structure and mechanics of biogels. We show how the structure of the material changes at the (thermally induced) gelation point and how factors such as concentration and polymer length determine the architecture, and with that, the mechanical properties. The correlation of the gel mechanics and the structural parameters obtained from SAXS experiments is essential in the design of future (synthetic) mimics of biopolymer networks.

    We investigate the properties of massive, dense clouds formed in a barred galaxy and their possible relation to star formation, performing a two-dimensional hydrodynamical simulation with the gravitational potential obtained from the 2Mass data from the barred spiral galaxy, M83. Since the environment for cloud formation and evolution in the bar region is expected to be different from that in the spiral arm region, barred galaxies are a good target to study the environmental effects on cloud formation and the subsequent star formation. Our simulation uses for an initial 80 Myr an isothermal flow of non-self gravitating gas in the barred potential, then including radiative cooling, heating and self-gravitation of the gas for the next 40 Myr, during which dense clumps are formed. We identify many cold, dense gas clumps for which the mass is more than $10^4M_{\\odot}$ (a value corresponding to the molecular clouds) and study the physical properties of these clumps. The relation of the velocity dispersion of the i...

  20. Formation of the first stars

    International Nuclear Information System (INIS)

    Understanding the formation of the first stars is one of the frontier topics in modern astrophysics and cosmology. Their emergence signalled the end of the cosmic dark ages, a few hundred million years after the Big Bang, leading to a fundamental transformation of the early Universe through the production of ionizing photons and the initial enrichment with heavy chemical elements. We here review the state of our knowledge, separating the well understood elements of our emerging picture from those where more work is required. Primordial star formation is unique in that its initial conditions can be directly inferred from the Λ cold dark matter (ΛCDM) model of cosmological structure formation. Combined with gas cooling that is mediated via molecular hydrogen, one can robustly identify the regions of primordial star formation, the so-called minihalos, having total masses of ∼106 M⊙ and collapsing at redshifts z ≃ 20–30. Within this framework, a number of studies have defined a preliminary standard model, with the main result that the first stars were predominantly massive. This model has recently been modified to include a ubiquitous mode of fragmentation in the protostellar disks, such that the typical outcome of primordial star formation may be the formation of a binary or small multiple stellar system. We will also discuss extensions to this standard picture due to the presence of dynamically significant magnetic fields, of heating from self-annihalating WIMP dark matter, or cosmic rays. We conclude by discussing possible strategies to empirically test our theoretical models. Foremost among them are predictions for the upcoming James Webb space telescope (JWST), to be launched ∼2018, and for ‘stellar archaeology’, which probes the abundance pattern in the oldest, most-metal poor stars in our cosmic neighborhood, thereby constraining the nucleosynthesis inside the first supernovae.
