    Carlos Chagas was born on 9 July 1878 in the farm "Bon Retiro" located close to the City of Oliveira in the interior of the State of Minas Gerais, Brazil. He started his medical studies in 1897 at the School of Medicine of Rio de Janeiro. In the late XIX century, the works by Louis Pasteur and Robert Koch induced a change in the medical paradigm with emphasis in experimental demonstrations of the causal link between microbes and disease. During the same years in Germany appeared the pathological concept of disease, linking organic lesions with symptoms. All these innovations were adopted by the reforms of the medical schools in Brazil and influenced the scientific formation of Chagas. Chagas completed his medical studies between 1897 and 1903 and his examinations during these years were always ranked with high grades. Oswaldo Cruz accepted Chagas as a doctoral candidate and directed his thesis on "Hematological studies of Malaria" which was received with honors by the examiners. In 1903 the director appointed Chagas as research assistant at the Institute. In those years, the Institute of Manguinhos, under the direction of Oswaldo Cruz, initiated a process of institutional growth and gathered a distinguished group of Brazilian and foreign scientists. In 1907, he was requested to investigate and control a malaria outbreak in Lassance, Minas Gerais. In this moment Chagas could not have imagined that this field research was the beginning of one of the most notable medical discoveries. Chagas was, at the age of 28, a Research Assistant at the Institute of Manguinhos and was studying a new flagellate parasite isolated from triatomine insects captured in the State of Minas Gerais. Chagas made his discoveries in this order: first the causal agent, then the vector and finally the human cases. These notable discoveries were carried out by Chagas in twenty months. At the age of 33 Chagas had completed his discoveries and published the scientific articles that gave him world

Mas, além dele, alguns outros reformadores influenciaram decisivamente o futuro desenvolvimento do Protestantismo. Um destes representantes foi Huldrych Zwingli (1484 - 1531, o reformador de Zurique na Suíça, que desenvolveu uma concepção religiosa própria. Zwingli não foi somente o líder teológico mais importante de Zurique, mas também o responsável pela divulgação da Reforma na Confederação Helvética. Além disso, criou a base teológica e intelectual, na qual, um pouco mais tarde, João Calvino (1509 - 1564 pôde continuar e desenvolver sua concepção de teologia e política. - Infelizmente, a vida e obra de Zwingli, a sua teologia, como as suas idéias políticas e sociais são pouco conhecidas no Brasil.

  19. Robust Face Sketch Style Synthesis.

    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.

    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...

    Fuzzy sketches, introduced as a link between biometry and cryptography, are a way of handling biometric data matching as an error correction issue. We focus here on iris biometrics and look for the best error-correcting code in that respect. We show that two-dimensional iterative min-sum decoding leads to results near the theoretical limits. In particular, we experiment our techniques on the Iris Challenge Evaluation (ICE) database and validate our findings.

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

    Science.gov (United States)

    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. PMID:26962452

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.

    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.

    It is commonly recognized that free-hand sketch maps are influenced by cognitive impacts and therefore sketch maps are incomplete, distorted, and schematized. This makes it difficult to achieve a one-to-one alignment between a sketch map and its corresponding geo-referenced metric map. Nevertheless, sketch maps are still useful to communicate spatial knowledge, indicating that sketch maps contain certain spatial information that is robust to cognitive impacts.

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.

    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.

    We propose Sketched Online Newton (SON), an online second order learning algorithm that enjoys substantially improved regret guarantees for ill-conditioned data. SON is an enhanced version of the Online Newton Step, which, via sketching techniques enjoys a running time linear in the dimension and sketch size. We further develop sparse forms of the sketching methods (such as Oja's rule), making the computation linear in the sparsity of features. Together, the algorithm eliminates all computati...

  16. Geometric Feature Based Face-Sketch Recognition

    OpenAIRE

    Pramanik, Sourav; Bhattacharjee, Debotosh

    2013-01-01

    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...

    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.

  16. Ḥanafī Biographical Dictionaries: A Survey

    Directory of Open Access Journals (Sweden)

    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.

    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 Since human life passes through an irreversible time axis, the passage of time makes us face with the idea of finiteness. As people age there is a change in their time perception and in the idea of their own death. With the aim of studying the changes related to their own temporality, this study analyses biographical trajectories of people in the fourth age. The analysis is based on three pillars: vital projects, organization of everyday life and bodily changes. An exploratory qualitative study was carried out based on 23 biographical interviews that constituted an intentional sample of self-validated persons, born between 1917 and 1932, from different socio-economic status and residing in the Metropolitan Area of Buenos Aires, Argentina. Results suggest that for people in their fourth age, time perception is narrow.

    Full Text Available The paper applies an interdisciplinary perspective to a fictional text showing that fractals as mathematical models are a powerful tool for conceptualizing life experience in biographical narratives. The multilevel construction of Chatterton by Peter Ackroyd is explored on the basis of fractal metaphor theory. This research focuses on the LIFE IS A STORY conceptual fractal metaphor which is built up on analogical mappings, mental space connections, and blends. The fractal model of metaphor in biographical narrative, which is assigned to the formula LIFE IS A STORY f (1 + f (2 + f (3 + … + f (n, contains the mental space of the intentional source domain story, which provides a way to structure the understanding of the limiting target domain of the concept life. Fractal metaphors aim at making the conceptual metaphor flexible and dynamic, renewing its ability of self-development and self-perfection, transforming itself into one of the means of changeable conceptualization of reality.

    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.

    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.

  19. Building Hierarchical Representations for Oracle Character and Sketch Recognition.

    2016-01-01

    In this paper, we study oracle character recognition and general sketch recognition. First, a data set of oracle characters, which are the oldest hieroglyphs in China yet remain a part of modern Chinese characters, is collected for analysis. Second, typical visual representations in shape- and sketch-related works are evaluated. We analyze the problems suffered when addressing these representations and determine several representation design criteria. Based on the analysis, we propose a novel hierarchical representation that combines a Gabor-related low-level representation and a sparse-encoder-related mid-level representation. Extensive experiments show the effectiveness of the proposed representation in both oracle character recognition and general sketch recognition. The proposed representation is also complementary to convolutional neural network (CNN)-based models. We introduce a solution to combine the proposed representation with CNN-based models, and achieve better performances over both approaches. This solution has beaten humans at recognizing general sketches. PMID:26571529

    Full Text Available The qualitative research interview engages with experience of social reality in sites of social interaction. Research interview respondents provide insight in biographical interviews into the significance of critical change processes for their individual and collective learning. Auto/biographical narratives of learning, are emergent, evolving accounts produced in a learning space hedged in by the demands of the "reflexive project of the self" which throw the individual more than ever before in processes of lifelong or life-wide learning onto their biographical resources. These resources can be understood as representing individual learning processes which are capable of furthering the creation of new cultural and social structures of experience, new forms of biographical knowledge which emerge out of the precarious balancing-act between routines and learning transitions. Research interviews embedded in interaction and participant reflexivity, addressing the learning transitions told in talk, access the construction of knowledge as adults move on to new biographical spaces and position themselves anew.

    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

    Saving of toner/ink consumption is an important task in modern printing devices. It has a positive ecological and social impact. We propose technique for converting print-job pictures to a recognizable and pleasant color sketches. Drawing a "pencil sketch" from a photo relates to a special area in image processing and computer graphics - non-photorealistic rendering. We describe a new approach for automatic sketch generation which allows to create well-recognizable sketches and to preserve partly colors of the initial picture. Our sketches contain significantly less color dots then initial images and this helps to save toner/ink. Our bio-inspired approach is based on sophisticated edge detection technique for a mask creation and multiplication of source image with increased contrast by this mask. To construct the mask we use DoG edge detection, which is a result of blending of initial image with its blurred copy through the alpha-channel, which is created from Saliency Map according to Pre-attentive Human Vision model. Measurement of percentage of saved toner and user study proves effectiveness of proposed technique for toner saving in eco-friendly printing mode.

  10. 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...

    Face sketch synthesis has wide applications in digital entertainment and law enforcement. Although there is much research on face sketch synthesis, most existing algorithms cannot handle some nonfacial factors, such as hair style, hairpins, and glasses if these factors are excluded in the training set. In addition, previous methods only work on well controlled conditions and fail on images with different backgrounds and sizes as the training set. To this end, this paper presents a novel method that combines both the similarity between different image patches and prior knowledge to synthesize face sketches. Given training photo-sketch pairs, the proposed method learns a photo patch feature dictionary from the training photo patches and replaces the photo patches with their sparse coefficients during the searching process. For a test photo patch, we first obtain its sparse coefficient via the learnt dictionary and then search its nearest neighbors (candidate patches) in the whole training photo patches with sparse coefficients. After purifying the nearest neighbors with prior knowledge, the final sketch corresponding to the test photo can be obtained by Bayesian inference. The contributions of this paper are as follows: 1) we relax the nearest neighbor search area from local region to the whole image without too much time consuming and 2) our method can produce nonfacial factors that are not contained in the training set and is robust against image backgrounds and can even ignore the alignment and image size aspects of test photos. Our experimental results show that the proposed method outperforms several state-of-the-arts in terms of perceptual and objective metrics. PMID:25879946

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

    Directory of Open Access Journals (Sweden)

    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.

    2011-01-01

    Distance computation is one of the most fundamental primitives used in communication networks. The cost of effectively and accurately computing pairwise network distances can become prohibitive in large-scale networks such as the Internet and Peer-to-Peer (P2P) networks. To negotiate the rising need for very efficient distance computation, approximation techniques for numerous variants of this question have recently received significant attention in the literature. The goal is to preprocess the graph and store a small amount of information such that whenever a query for any pairwise distance is issued, the distance can be well approximated (i.e., with small stretch) very quickly in an online fashion. Specifically, the pre-processing (usually) involves storing a small sketch with each node, such that at query time only the sketches of the concerned nodes need to be looked up to compute the approximate distance. In this paper, we present the first theoretical study of distance sketches derived from distance ora...

    2010-09-01

    The decision to publish the journals Der Schmerz and Narkose und Anaesthesie in 1928 was an important step towards the professionalization of anaesthesiology in Germany. The appearance of both journals, which for economic reasons merged into Schmerz - Narkose - Anaesthesie 1 year later, was initiated and vehemently supported by Jewish physicians. As editors and co-editors they were deeply involved with the editorial tasks of the journals for years from the early beginnings. When the National Socialistic Party took over the government in Germany many of the Jewish colleagues were forced to quit their editorial tasks, were eliminated and replaced by "Arians", they were persecuted and often arrested, forced to emigrate or decided to commit suicide due to inhumane personal circumstances. It is our intention to recall the biography and the terrible fate of the nearly unknown Jewish members of the editorial board of the first German anaesthesia journals. Moreover the biographic sketches promote a continuous discussion about the victims of an inhumane and barbarous ideology. PMID:20842476

    1990-01-01

    We present a multi-scale representation of grey-level shape, called scale-space primal sketch, that makes explicit features in scale-space as well as the relations between features at different levels of scale. The representation gives a qualitative description of the image structure that allows for extraction of significant image structure --- stable scales and regions of interest --- in a solely bottom-up data-driven manner. Hence, it can be seen as preceding further processing, which can t...

  17. Ethical Selves: A Sketch for a Theory of Relational Authenticity

    Directory of Open Access Journals (Sweden)

    Natalie Fletcher

    2013-01-01

    Full Text Available Philosophers who show interest in authenticity tend to narrowly focus on its capacity to help people evade conformity and affirm individuality, a simplistic reduction that neglects authenticity’s moral potential and gives credence to the many critics who dismiss it as a euphemism for excessive individualism. Yet when conceived relationally, authenticity can also allow for worthy human flourishing without falling prey to conformity’s opposite extreme—egoism. This essay proposes a sketch for a relational conception of authenticity that can help prevent the often-destructive excess of egoism while also offsetting the undesirable deficiency of heteronomy, concertedly moving agents towards socially responsible living.

  1. BioGraphE: High-performance bionetwork analysis using the Biological Graph Environment

    Energy Technology Data Exchange (ETDEWEB)

    Chin, George; Chavarría-Miranda, Daniel; Nakamura, Grant C.; Sofia, Heidi J.

    2008-05-28

    Graphs and networks are common analysis representations for biological systems. Many traditional graph algorithms such as k-clique, k-coloring, and subgraph matching have great potential as analysis techniques for newly available data in biology. Yet, as the amount of genomic and bionetwork information rapidly grows, scientists need advanced new computational strategies and tools for dealing with the complexities of the bionetwork analysis and the volume of the data. We introduce a computational framework for graph analysis called the Biological Graph Environment (BioGraphE), which provides a general, scalable integration platform for connecting graph problems in biology to optimized computational solvers and high-performance systems. This framework enables biology researchers and computational scientists to identify and deploy network analysis applications and to easily connect them to efficient and powerful computational software and hardware that are specifically designed and tuned to solve complex graph problems. In our particular application of BioGraphE to support network analysis in genome biology, we investigate the use of a Boolean satisfiability solver known as Survey Propagation as a core computational solver and high-performance parallel systems that utilize multi-threaded architectures. In our application of BioGraphE to conduct bionetwork analysis of homology networks, we found that BioGraphE and a custom, parallel implementation of the Survey Propagation SAT solver were capable of solving very large bionetwork problems at high rates of execution on different high-performance computing platforms.

  8. Multi-pen Sketch Recognition in a Learning Environment

    Directory of Open Access Journals (Sweden)

    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.

    2011-01-01

    The objective of this paper was to provide an update on NASA s current tools for design and analysis of hybrid wing body (HWB) aircraft with an emphasis on Vehicle Sketch Pad (VSP). NASA started HWB analysis using the Flight Optimization System (FLOPS). That capability is enhanced using Phoenix Integration's ModelCenter(Registered TradeMark). Model Center enables multifidelity analysis tools to be linked as an integrated structure. Two major components are linked to FLOPS as an example; a planform discretization tool and VSP. The planform discretization tool ensures the planform is smooth and continuous. VSP is used to display the output geometry. This example shows that a smooth & continuous HWB planform can be displayed as a three-dimensional model and rapidly sized and analyzed.

  12. 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.

    Berendonk, C; Stanek, S; Schönit, M; Kaspar, R; Bär, M; Kruse, A

    2011-02-01

    In nursing care for people with dementia, biographical work is a popular concept. In the literature and practice, many different viewpoints of the way biographical work can/should be promoted exist. In the DEMIAN concept, a nursing concept to promote emotional well-being for people with dementia, it is also of major significance. This article gives an overview of the importance of biographical work in caring for people with dementia. In particular, the role and arrangement of biographical work in the DEMIAN concept are described. Within the anamnesis of the DEMIAN concept, meaningful themes are identified in conversations with different participants (person with dementia, reference persons, and care workers) and through observations. From these findings, specific interventions, aimed at supporting emotional well-being of people with dementia, are derived and integrated into everyday nursing care to promote emotional well-being. The potential of the DEMIAN nursing concept are discussed and further possibilities are highlighted. PMID:21359631

    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.

    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.

    2015-08-01

    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.

  5. 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

  7. What is life? with Mind and Matter and Autobiographical Sketches

    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...

  8. Sketching the pion's valence-quark generalised parton distribution

    Directory of Open Access Journals (Sweden)

    C. Mezrag

    2015-02-01

    Full Text Available 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, Hπv(x,ξ,t. Our analysis focuses primarily on ξ=0, although we also capitalise on the symmetry-preserving nature of the RL truncation by connecting Hπv(x,ξ=±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 Hπv(x,0,t, expressed as the Radon transform of a single amplitude. Therewith we obtain results for Hπv(x,0,t and the associated impact-parameter dependent distribution, qπv(x,|b→⊥|, which provide a qualitatively sound picture of the pion's dressed-quark structure at a hadronic scale. We evolve the distributions to a scale ζ=2 GeV, so as to facilitate comparisons in future with results from experiment or other nonperturbative methods.

    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...

  11. Exploring Textiles in Architecture through Tangible Three-Dimensional Sketching Tools

    DEFF Research Database (Denmark)

    Heimdal, Elisabeth Jacobsen; Lenau, Torben Anker; O'Mahony, Marie

    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...

  12. Sharing one biographical detail elicits priming between famous names: Empirical and computational approaches

    Full Text Available In this paper three experiments and corresponding model simulations are reported that investigate the priming of famous name recognition in order to explore the structure of the part of the semantic system dealing with people. Consistent with empirical findings, novel computational simulations using Burton et al.'s interactive activation and competition model point to a conceptual distinction between how priming is initiated in single- and double-familiarity tasks, indicating that priming should be weaker or non-existent for the single-familiarity task. Experiment One demonstrates that, within a double-familiarity framework using famous names, categorial and associative priming are reliable effects. Pushing the model to the limit, it predicts that pairs of celebrities who are neither associatively- nor categorially-related but who share single biographical features, both died in a car crash for example, should prime each other. Experiment Two investigated this in a double familiarity task but the effect was not observed. We therefore simulated and realized a pairwise learning task that was conceptually similar to the double-familiarity decision task but allowed to strengthen the underlying connections. Priming based on a single biographical feature could be found both in simulations and the experiment. The effect was not due to visual or name similarity which were controlled for and participants did not report using the biographical links between the people to learn the pairs. The results are interpreted to lend further support to structural models of the memory for persons. Furthermore, the results are consistent with the idea that episodic features known about people are stored in semantic memory and are automatically activated when encountering that person.

    This paper uses a biographical and life-course perspective to explore some of the key narratives of return among return migrants to Ireland, focusing in particular on the themes of family, child-rearing, relationship breakdown and ‘settling down’. The ways in which return migrants use the concept of life-course transitions in order to make sense of and narrate their migration stories is explored. I argue that their narratives reflect a normative association of life stage with place, and that ...

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

    2016-08-01

    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

    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.

    Liamputtong, Pranee; Suwankhong, Dusanee

    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. PMID:25922881

    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

    1995-06-01

    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. Dit skyn asof minder navorsing oor vroulike as oor manlike entrepreneurs gedoen is. Ten spyte van aannames in die verband, bestaan min empiriese gegewens oor die biografiese agtergronde en sake-situasie van respektiewelik wit en swart Suid-Afrikaanse entrepreneurs. Swart en vroulike entrepreneurs is in meeste gemeenskappe minderheidsgroepe en is nog nie in diepte bestudeer nie, daarom die huidige studie. Die

  5. Autobiographical reasoning in life narratives buffers the effect of biographical disruptions on the sense of self-continuity.

    2015-01-01

    Personal identity depends on synchronic coherence and diachronic continuity of the self. Autobiographical remembering and autobiographical knowledge as well as the stability of bodily integrity, of social roles, of significant others and of physical and sociocultural environment have been suggested as supporting a pre-reflective sense of self-continuity. Stark biographical discontinuities or disruptions in these areas may destabilise the sense of self-continuity. To test the hypothesis that autobiographical reasoning in life narratives helps to compensate the effects of biographical discontinuities on the sense of self-continuity, life narratives of a lifespan sample with the ages of 16, 20, 24, 28, 44 and 69 (N = 150, 78 female) were investigated. Results confirm that if, and only if there have been biographical disruptions in the past four years, then autobiographical reasoning correlates positively with a sense of self-continuity. The findings contradict the thesis that mere remembering of past episodes is sufficient to maintain a sense of self-continuity under conditions of biographical change. PMID:24912017

    2002-05-01

    Full Text Available The article analyzes how biographical-narrative research has currently become a perspective or specific approach in educational research, rather than just another qualitative methodology to be added to the rest. This type of research changes the usual concepts of what is considered knowledge in social science, and what is important to know. However, since modern times there has been a methodological deficiency in the justification of this type of research (validity, generalization and reliability. This study pulls together and describes the main lines of support for autobiographical accounts, critically analyzing the theoretical and epistemological disputes that have arisen in the last few years (positivism vs. hermeneutics, paradigmatic method vs. narration of data analysis. The paper also deals with the limitations and epistemological problems that arise from the defense of a strictly narrative data focus, and how this can be compatible with the paradigmatic ways of knowing.

    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

    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.

  3. Analysis of the WWER-440 AER2 rod ejection benchmark by the SKETCH-N code

    International Nuclear Information System (INIS)

    The neutron kinetics code SKETCH-N has been recently extended to treat hexagonal geometry using a polynomial nodal method based on the conformal mapping of a hexagon into a rectangle. Basic features of the code are outlined. Results of the steady-state benchmark calculations demonstrate excellent accuracy of the nodal method. To test a neutron kinetics module for WWER applications, the second AER rod ejection benchmark is computed and the results are compared with the results of the production WWER codes: BIPR8, DYN3D, HEXTRAN and KIKO3D. The steady-state results show that the SKETCH-N code gives an ejected control rod worth close to that of BIPR8 and HEXTRAN. The assembly power distribution is compared with the DYN3D results. Maximum discrepancies of about 5% are found in the power of peripheral assemblies and assemblies with partially inserted control rods (Authors)

  5. A prototype sketch-based architecture modeling system with traditional design habits

    OpenAIRE

    2008-01-01

    Widely used for architectural design, CAD systems such as AutoCAD, 3ds MAX, provide powerful modeling functionality. However, they are often too complex for an architect to use, especially during the conceptualization stage involving primarily sketching of design ideas. Also, interactions with conventional CAD systems are typically driven by mouse and keyboard, but these devices cannot be used as freely as a pencil. For an architect, a tabletPC with stylus provides an ideal interface for desi...

    As an emerging field, cognitive map kept playing a significant role in geography these decades. To date, there are two dominant methods to externalize human's internal cognitive map, namely, multidimensional scaling (MDS) and skech mapping. However, among most recent researches on cognitive map, the differences between both methods are always ignored. The usage of one method over another is still under scrutiny. In order to shed light on the similarity or distinctions of MDS configuration and sketch mapping, we conducted an experiment on Beijing residents by requesting a sketch of the region within 3rd Ring and meanwhile extracting distance estimates between 8 landmarks. Employing the Bidimensional regression along with standard deviational ellipse, we studied the global and local distortions among two kinds of cognitive maps and quantitatively measure the overall and local cognitive maps distortions. Besides, we use Monte Carlo simulation method to calculate the radius of distortion for the Distortion Index (DI). It shows that the average cognitive distortion of habitants in Beijing is 2km to 3km, and the distortion takes 2nd-ring road as a border, displaying a southwest-northeast diagonal stretch and an east-west contracted tendency. The distortion in the two methods is remarkably both correlated with factors, such as travel frequency and years of residence. Comparing two methods, it turned out that sketch map was more consistent with real map, while the distortion orientations of sketch map resembled MDS configuration. Finally, we gave possible reasons with regard to above conclusions and advices for future usage of two methods.

    International audience A new profile-based anomaly detection and characterization procedure is proposed. It aims at performing prompt and accurate detection of both short-lived and long-lasting low-intensity anomalies, without the recourse of any prior knowledge of the targetted traffic. Key features of the algorithm lie in the joint use of random projection techniques (sketches) and of a multiresolution non Gaussian marginal distribution modeling. The former enables both a reduction in th...

    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.

    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.

    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

  17. 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.

    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.

  5. Coupling of the thermal-hydraulics TRAC codes with 3-D neutron kinetics code SKETCH-N

    International Nuclear Information System (INIS)

    Since 1997, the Japan Atomic Energy Research Institute (JAERI) has been developing the three-dimensional transient analysis codes: J-TRAC/SKETCH-N code system for pressurised water reactor (PWR), and the TRAC-BEY SKETCH-N for boiling water reactor (BWR). The J-TRAC code, developed by JAERI, has a framework based on the TRAC-PF1, which is best estimate system transient analysis code having the capability to simulate PWR system components and three-dimensional core in cylindrical R-9-Z coordinates. The TRAC-BF1 is a BWR system analysis code. The neutronics code SKETCH-N can solve the steady-state and kinetics forms of neutron diffusion equations in X-Y-Z geometry. The efficient polynomial and semi-analytic nodal methods based on the nonlinear iteration procedure are used in the code. Coupling with the TRAC codes is performed using the interface module based on the message-passing library Parallel Virtual Machine (PVM). The interface module is responsible for data transfer between the codes, mapping of the data between different spatial meshes and synchronization of the time stepping. Verification of the coupled TRAC/SKETCH code system has been performed against light water reactor (LWR) transient benchmark problems. J-TRAC/SKETCH has been verified by NEACRP PWR rod ejection benchmark and NEA/NSC PWR rod withdrawal benchmark. Verification of the TRAC-BF1/SKETCH-N has been performed using NEACRP BWR cold water injection benchmark. TRAC/SKETCH numerical results and a comparison with the other codes are given in the paper. The second part of the paper presents current status of the out-of-pile experiments at JAERI on BWR stability to assess and improve the TRAC-BF1 code. (authors)

    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.

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

    Watkins, Hannah; Bond, Clare; Butler, Rob

    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.

    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

    2013-01-01

    Conceptual design is the most fluid phase of aircraft design. It is important to be able to perform large scale design space exploration of candidate concepts that can achieve the design intent to avoid more costly configuration changes in later stages of design. This also means that conceptual design is highly dependent on the disciplinary analysis tools to capture the underlying physics accurately. The required level of analysis fidelity can vary greatly depending on the application. Vehicle Sketch Pad (VSP) allows the designer to easily construct aircraft concepts and make changes as the design matures. More recent development efforts have enabled VSP to bridge the gap to high-fidelity analysis disciplines such as computational fluid dynamics and structural modeling for finite element analysis. This paper focuses on the current state-of-the-art geometry modeling for the automated process of analysis and design of low-boom supersonic concepts using VSP and several capability-enhancing design tools.

    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.

    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.

    Even seemingly simple drawings, diagrams, and sketches are hard for computer programs to interpret, because these inputs can be highly variable in several respects. This variability corrupts the expected mapping between a prior model of a configuration and an instance of it in the scene. We propose a scheme for representing ambiguity explicitly, within a subgraph matching framework, that limits its impact on the computational and program complexity of matching. First, ambiguous alternative structures in the input are explicitly represented by coupled subgraphs of the data graph, using a class of segmentation post-processing operations termed graph elaboration. Second, the matching process enforces mutual exclusion constraints among these coupled alternatives, and preferences or rankings associated with them enable better matches to be found early on by a constrained optimization process. We describe several elaboration processes, and extend a straightforward constraint-based subgraph matching scheme to elaborated data graphs. The discussion focuses on the domain of human stick figures in diverse poses.

    Full Text Available Sketch-based interfaces provide a powerful, natural and intuitive way for users to interact with an application. By combining a sketch-based interface with a physically simulated environment, an application offers the means for users to rapidly sketch a set of objects, like if they are doing it on piece of paper, and see how these objects behave in a simulation. In this paper we present SketchyDynamics, a library that intends to facilitate the creation of applications by rapidly providing them a sketch-based interface and physics simulation capabilities. SketchyDynamics was designed to be versatile and customizable but also simple. In fact, a simple application where the user draws objects and they are immediately simulated, colliding with each other and reacting to the specified physical forces, can be created with only 3 lines of code. In order to validate SketchyDynamics design choices, we also present some details of the usability evaluation that was conducted with a proof-of-concept prototype

    This article summarizes the basic facts and ideas concerning the formation and evolution of cataclysmic variables (CVs). It is shown why the formation of CVs must involve huge losses of mass and orbital angular momentum, very likely via a common envelope evolution. A brief discussion of the principles of the long-term evolution of semi-detached binaries follows. Finally a brief sketch of CV evolution is given.

    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.

  20. Vehicle Sketch Pad: a Parametric Geometry Modeler for Conceptual Aircraft Design

    Science.gov (United States)

    Hahn, Andrew S.

    2010-01-01

    The conceptual aircraft designer is faced with a dilemma, how to strike the best balance between productivity and fidelity? Historically, handbook methods have required only the coarsest of geometric parameterizations in order to perform analysis. Increasingly, there has been a drive to upgrade analysis methods, but these require considerably more precise and detailed geometry. Attempts have been made to use computer-aided design packages to fill this void, but their cost and steep learning curve have made them unwieldy at best. Vehicle Sketch Pad (VSP) has been developed over several years to better fill this void. While no substitute for the full feature set of computer-aided design packages, VSP allows even novices to quickly become proficient in defining three-dimensional, watertight aircraft geometries that are adequate for producing multi-disciplinary meta-models for higher order analysis methods, wind tunnel and display models, as well as a starting point for animation models. This paper will give an overview of the development and future course of VSP.

  1. Application of CART3D to Complex Propulsion-Airframe Integration with Vehicle Sketch Pad

    Science.gov (United States)

    Hahn, Andrew S.

    2012-01-01

    Vehicle Sketch Pad (VSP) is an easy-to-use modeler used to generate aircraft geometries for use in conceptual design and analysis. It has been used in the past to generate metageometries for aerodynamic analyses ranging from handbook methods to Navier-Stokes computational fluid dynamics (CFD). As desirable as it is to bring high order analyses, such as CFD, into the conceptual design process, this has been difficult and time consuming in practice due to the manual nature of both surface and volume grid generation. Over the last couple of years, VSP has had a major upgrade of its surface triangulation and export capability. This has enhanced its ability to work with Cart3D, an inviscid, three dimensional fluid flow toolset. The combination of VSP and Cart3D allows performing inviscid CFD on complex geometries with relatively high productivity. This paper will illustrate the use of VSP with Cart3D through an example case of a complex propulsion-airframe integration (PAI) of an over-wing nacelle (OWN) airliner configuration.

    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

    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.

    2016-06-01

    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.

  7. Validation of the SimSET simulation package for modeling the Siemens Biograph mCT PET scanner

    International Nuclear Information System (INIS)

    Monte Carlo simulation provides a valuable tool in performance assessment and optimization of system design parameters for PET scanners. SimSET is a popular Monte Carlo simulation toolkit that features fast simulation time, as well as variance reduction tools to further enhance computational efficiency. However, SimSET has lacked the ability to simulate block detectors until its most recent release. Our goal is to validate new features of SimSET by developing a simulation model of the Siemens Biograph mCT PET scanner and comparing the results to a simulation model developed in the GATE simulation suite and to experimental results. We used the NEMA NU-2 2007 scatter fraction, count rates, and spatial resolution protocols to validate the SimSET simulation model and its new features. The SimSET model overestimated the experimental results of the count rate tests by 11–23% and the spatial resolution test by 13–28%, which is comparable to previous validation studies of other PET scanners in the literature. The difference between the SimSET and GATE simulation was approximately 4–8% for the count rate test and approximately 3–11% for the spatial resolution test. In terms of computational time, SimSET performed simulations approximately 11 times faster than GATE simulations. The new block detector model in SimSET offers a fast and reasonably accurate simulation toolkit for PET imaging applications. (note)

  9. Talking about Artifacts: Preschool Children’s Explorations with Sketches, Stories, and Tangible Objects

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Exploratory learning is recognized as a developmentally appropriate practice in early childhood education. During exploration, exposure to new things guides children in the acquisition of knowledge, while interactions with a range of familiar and unfamiliar artifacts can support developmental integration. Exploratory activity may occur spontaneously at any time, but it can also be structured and guided to achieve specific curricular and developmental goals. This paper explores preschool children’s interactions during semi-structured exploratory activities in three different conditions. Thirty-five 4- to 5-year-old children, from six preschool classrooms, were randomly assigned to three different conditions. Each condition included the same set of 13 different artifacts that were either artistically rendered in black ink on white paper (sketch condition, included in a children’s story book (book condition, or had the real artifact itself (tangible object condition. Children’s exploration and interactions were videotaped and analyzed to see which, if any, of the three conditions would appear to stimulate and encourage early engineering thinking the most. Initial hypothesis was that the tangible object condition would appear to be the most beneficial. Findings showed that this condition elicited the longest discussions and interactions with the artifacts, and it was also the condition during which children were demonstrating more knowledge and ideas with regard to possible functions of the artifacts. Regarding whether there was a condition that stimulated more interest toward specific artifacts, no clear pattern among the three conditions appeared. Implications are discussed in terms of preschool Science, Technology, Engineering, and Mathematics (STEM and child development.

    The article is an attempt of a new outlook first of all upon scientific output of many years' (the years 1878 - 1909) lecturer on Russian State Law in the Imperial University of Warsaw--Aleksandr Lwowicz Błok. Historians of literature, researchers of life and output of the scientist's son, an eminent poet-symbolist Aleksandr A. Błok, to a high degree were able to reconstruct lot of life and vicissitudes of the Warsaw professor. Thanks to the preserved university archival materials it was possible to add many details to Błok's biography, especially concerning his professional problems. They were connected with dramatic events in personal life of the professor. According to relations of the part of his university co-workers and students, the circumstances even brought about the symptoms of the mental illness. Prematurely elderly he was a man deeply miserable, lonely and deprived of understanding by associates. Up till now his scientific output has not been described precisely enough. Not numerous memories of his contemporaries (Szymon Askenazy, Nikołaj Dubrowskij) and even inconspicuous modern researches of the Polish (Janusz Woliński) brought about, in the author's opinion, too simplified and schematic character-sketch of Błok as a Russificator and nationalist, mediocre scholar and much worse lecturer. A scientific output of Błok is, indeed, inostensible--he published 2 books only--Master's thesis entitled: Władza państwowa w społeczeństwie europejskim. Poglad na polityczna teorie Lorenza Steina i na francuska rzeczywistość polityczna (1880) [State Authority in European Society. Outlook upon Political Theory of Lorenz Stein and French Political Facts (1880)] and Literatura polityczna w Rosj i o Rosji (1884) [Political Literature in Russia and on Russia (1884)] as an introduction to his course in State Law. Two thirds, so over 20 years of work, he gave to the not accomplished conception of creating a new classification of sciences that together with its

    2005-01-01

    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

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

    Directory of Open Access Journals (Sweden)

    Arif Muntasa

    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.

    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.

  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)

  8. 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

    Full Text Available It discusses the meanings given by 14 physical education teachers about their experiences with the continued formation process. It is a (auto biographical narrative research, which used focal groups and interviews as tools for compiling the data. The colaborators are six male teachers and eight female teachers of municipal networks from Serra, Vitoria and Viana municipalities in the metropolitan region of Vitória, ES. The analyzes indicate that the assigned meanings are related to the collective need to reorganize institutional provided formations in dialogue with the political interests of teachers and the specificity of Physical Education as a curriculum component. In general, teachers consider the formation focused on practice and in the teaching profession as those that best reflect their expectations. The practice appears as a know-how to be appropriate from continued formetion to be experienced in school; a knowledge that, when apprehended, is reframed to produce other experiences.

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.

    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

    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 a first version of our sketch map was published by a Dutch professional journal, copies appeared in policy documents, and also in a commercial and popular atlas of the Netherlands. Moreover, the map led to a question in the Dutch parliament about the sustainability of bog reserves under 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 the potential threats from climate change by taking a number of adaptation measures that enhance the robustness of nature reserves.

    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

    The article sketches the history of naukoznawstwo (literally meaning the science connoisseurship or the science of science or science studies) in Poland from the 1910s to the end of the Cold War (1991), and the recovery of full political independence in 1993. It outlines the changing research perspectives of this interdisciplinary field of knowledge in Poland against a background of changing political conditions caused by the reconfigurations of the political order. The first part of the article concerns the period from the 1910s, when Poland was occupied by Russia, Prussia, and Austria, through the regaining of independence by Poland in 1918, the reconstruction of the state in 1918-1939; the second part--World War II; the third part--the period from the initial period of Soviet dominance (1944-1954) in Poland and simultaneously the beginnings of the Cold War (1947-1954), the period 1955-1956 (when the Polish state was liberated from Sovietization), through the different political crises in October 1956, March 1968, December 1970, and June 1976, to the emergence of the Independent Self-governing Trade Union Solidarity in September 1980, the end of the Cold War (1991), and the recovery of full political independence in 1993. The article outlines the fundamental achievements of prominent Polish scholars (among others K. Twardowski, M. Ossowska, S. Ossowski, T. Kotarbiński, K. Ajdukiewicz, S. Michalski, F. Znaniecki, B. Suchodolski, L. Fleck, M. Choynowski, Z. Modzelewski, S. Amsterdamski), politicians (among others B. Bierut, E. Krasowska), politicians and scholars (H. Jabłoński, S.

  10. Bulge Formation

    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.

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

    Pavel Khondzinsky

    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.

    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.

  15. Star formation

    International Nuclear Information System (INIS)

    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

    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

    2013-01-01

    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...

  11. 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.

    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.

    Document similarity search is an important problem that has many applications especially in outsourced data. With the wide spread of cloud computing, users tend to outsource their data to remote servers which are not necessarily trusted. This leads to the problem of protecting the privacy of sensitive data. We design and implement two secure similarity search schemes for textual documents utilizing locality sensitive hashing techniques for cosine similarity. While the first one provides very ...

  17. On Knowledge of Learning. A Phenomenological Sketch

    Full Text Available He word “learning” has the endless meanings. The learning occurs not only from knowledge but also as knowledge. Learning in this sense depends not only on our initiative. 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.

    What is envy and how can we define it so as to incorporate the emotion in economic models? Through referring on philosophical and psychological researches, this paper aims at deriving a stable and concise definition of the emotion of envy. Philosophy allows us to define the elements that form envy and to disentangle the latter from other emotions. Researches on psychology help us in understanding the affective and behavioural responses of the emotion. We conclude that envy arises from any unf...

    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

  4. Overcoming difficulties with caviar formation, desanding of converter I, Leuna, 1941

    Energy Technology Data Exchange (ETDEWEB)

    1941-01-01

    The life of a coal stall was in most cases limited by the grinding action of the solid components of the coal. The so-called caviar produced the greatest amount of difficulties. Its elimination was accomplished by the removal of the coarsest particle from the first converter, the converter 1 desanding. Before desanding was introduced, perforated thermocouple-protecting tubes and catalyst tubes almost ground through were found in almost every dismantling of the stalls. Small-scale and large-scale solutions to this problem were discussed. A sketch of desanding in converter I was given. Another sketch showed the pipe line of the HOLD from the converter to the pressure relief. A screen analysis of the converter I desanding and of the normal HOLD were made to determine the proportion of coarse and fine sludge. Curve A and curve B given on two graphs showed the percent distribution and the actual amount involved. Sheet 1 gave diagrams of the residue and damage by wear in converters 1 and 2 of stall 8. Sheet 4 showed a diagram of converter 1 with an inclined plane for desanding and sheet 8 gave the desanding results from a test on converter 1. The final conclusion drawn was that desanding of converter 1 completely eliminated the formation and settling of caviar in the coal stall converters. The desanding process was one in which about 10% of the sludge in the first converter was periodically withdrawn from the bottom of converter, often to be sent on to be combined with hot oil letdown for further processing. The desanding residue could be readily carbonized because the proportion of asphalt to solids was very good. 8 diagrams

    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.

  12. GLOBAL STAR FORMATION REVISITED

    International Nuclear Information System (INIS)

    A general treatment of disk star formation is developed from a dissipative multiphase model, with the dominant dissipation due to cloud collisions. The Schmidt-Kennicutt (SK) law emerges naturally for star-forming disks and starbursts. We predict that there should be an inverse correlation between Tully-Fisher law and SK law residuals. The model is extended to include a multiphase treatment of supernova feedback that leads to a turbulent pressure-regulated generalization of the star formation law and is applicable to gas-rich starbursts. Enhanced pressure, as expected in merger-induced star formation, enhances star formation efficiency. An upper limit is derived for the disk star formation rate in starbursts that depends on the ratio of global ISM to cloud pressures. We extend these considerations to the case where the interstellar gas pressure in the inner galaxy is dominated by outflows from a central active galactic nucleus (AGN). During massive spheroid formation, AGN-driven winds trigger star formation, resulting in enhanced supernova feedback and outflows. The outflows are comparable to the AGN-boosted star formation rate and saturate in the super-Eddington limit. Downsizing of both SMBH and spheroids is a consequence of AGN-driven positive feedback. Bondi accretion feeds the central black hole with a specific accretion rate that is proportional to the black hole mass. AGN-enhanced star formation is mediated by turbulent pressure and relates spheroid star formation rate to black hole accretion rate. The relation between black hole mass and spheroid velocity dispersion has a coefficient (Salpeter time to gas consumption time ratio) that provides an arrow of time. Highly efficient, AGN-boosted star formation can occur at high redshift.

  14. When efficient star formation drives cluster formation

    CERN Document Server

    Parmentier, G

    2008-01-01

    We investigate the impact of the star formation efficiency in cluster forming cores on the evolution of the mass in star clusters over the age range 1-100Myr, when star clusters undergo their infant weight-loss/mortality phase. Assuming a constant formation rate of gas-embedded clusters and a weak tidal field, we show that the ratio between the total mass in stars bound to the clusters over that age range and the total mass in stars initially formed in gas-embedded clusters is a strongly increasing function of the averaged local SFE, with little influence from any assumed core mass-radius relation. Our results suggest that, for young starbursts with estimated tidal field strength and known recent star formation history, observed cluster-to-star mass ratios, once corrected for the undetected clusters, constitute promising probes of the local SFE, without the need of resorting to gas mass estimates. Similarly, the mass ratio of stars which remain in bound clusters at the end of the infant mortality/weight-loss ...

    2015-01-01

    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.

    Bulges, often identified with the spheroidal component of a galaxy, have a complex pedigree. Massive bulges are generally red and old, but lower mass bulges have broader dispersions in color that may be correlated with disk colors. This suggests different formation scenarios. I will review possible formation sequences for bulges, describe the various signatures that distinguish these scenarios, and discuss implications for the high redshift universe.

    The author reviews current ideas and models in the problem of star formation from molecular cloud cores that are relatively isolated from the influences of other forming stars. He discusses the time scales, flow dynamics, and density and temperature structures applicable to each of the four stages of the entire process: (1) formation of a magnetized cloud core by ambipolar diffusion and evolution to a pivotal state of gravomagneto catastrophe; (2) self-similar collapse of the pivotal configuration and the formation of protostars, disks, and pseudo-disks; (3) onset of a magnetocentrifugally driven, lightly ionized wind from the interaction of an accretion disk and the magnetosphere of the central star, and the driving of bipolar molecular outflows; (4) evolution of pre-main-sequence stars surrounded by dusty accretion disks. For each of these stages and processes, he considers the characteristics of the molecular diagnostics needed to investigate the crucial aspects of the observational problem.

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...... PilX alleles was identified among genetically diverse meningococcal strains.

    What else can be said about star formation rate indicators that has not been said already many times over? The `coming of age' of large ground-based surveys and the unprecedented sensitivity, angular resolution and/or field-of-view of infrared and ultraviolet space missions have provided extensive, homogeneous data on both nearby and distant galaxies, which have been used to further our understanding of the strengths and pitfalls of many common star formation rate indicators. The synergy between these surveys has also enabled the calibration of indicators for use on scales that are comparable to those of star-forming regions, thus much smaller than an entire galaxy. These are being used to investigate star formation processes at the sub-galactic scale. I review progress in the field over the past decade or so.

  9. 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.

    Galaxy pairs provide a potentially powerful means of studying triggered star formation from galaxy interactions. We use a large cosmological N-body simulation coupled with a well-tested semi-analytic substructure model to demonstrate that the majority of galaxies in close pairs reside within cluster or group-size halos and therefore represent a biased population, poorly suited for direct comparison to 'field' galaxies. Thus, the frequent observation that some types of galaxies in pairs have redder colors than 'field' galaxies is primarily a selection effect. We use our simulations to devise a means to select galaxy pairs that are isolated in their dark matter halos with respect to other massive subhalos (N= 2 halos) and to select a control sample of isolated galaxies (N= 1 halos) for comparison. We then apply these selection criteria to a volume-limited subset of the 2dF Galaxy Redshift Survey with M{sub B,j} {le} -19 and obtain the first clean measure of the typical fraction of galaxies affected by triggered star formation and the average elevation in the star formation rate. We find that 24% (30.5 %) of these L* and sub-L* galaxies in isolated 50 (30) h{sup -1} kpc pairs exhibit star formation that is boosted by a factor of {approx}> 5 above their average past value, while only 10% of isolated galaxies in the control sample show this level of enhancement. Thus, 14% (20 %) of the galaxies in these close pairs show clear triggered star formation. Our orbit models suggest that 12% (16%) of 50 (30) h{sup -1} kpc close pairs that are isolated according to our definition have had a close ({le} 30 h{sup -1} kpc) pass within the last Gyr. Thus, the data are broadly consistent with a scenario in which most or all close passes of isolated pairs result in triggered star formation. The isolation criteria we develop provide a means to constrain star formation and feedback prescriptions in hydrodynamic simulations and a very general method of understanding

    Isothermal (i.e. time dependent) martensite formation in steel was first observed in the 40ies of the XXth century and is still treated as an anomaly in the description of martensite formation which is considered as a-thermal (i.e. independent of time). Recently, the clarification of the mechanism...... leading to isothermal kinetics acquired new practical relevance because of the identification of isothermal martensite formation as the most likely process responsible for enhanced performances of sub-zero Celsius treated high carbon steel products. In the present work, different iron based alloys are...... chosen to investigate time dependent martensite formation. Among them, a Fe-11wt%Ni-0.6wt%C model alloy and Fe-1.6wt%Cr-1wt%C (AISI 52100), Fe-17wt%Cr-7wt%Ni (AISI 631) and Fe-16wt%Cr-5wt%Ni (AISI 630) commercial steels.

    Habermas, Tilmann

    2011-01-01

    Autobiographical reasoning is the activity of creating relations between different parts of one's past, present, and future life and one's personality and development. It embeds personal memories in a culturally, temporally, causally, and thematically coherent life story. Prototypical autobiographical arguments are presented. Culture and socializing interactions shape the development of autobiographical reasoning especially in late childhood and adolescence. Situated at the intersection of cognitive and narrative development and autobiographical memory, autobiographical reasoning contributes to the development of personality and identity, is instrumental in efforts to cope with life events, and helps to create a shared history.

  16. What I see when I think it's about me: people low in rejection-sensitivity downplay cues of rejection in self-relevant interpersonal situations.

    Science.gov (United States)

    Romero-Canyas, Rainer; Downey, Geraldine

    2013-02-01

    Gauging one's impression on a potential mate is challenging. There is a need to make reasonably accurate inferences from subtle, dynamic facial expressions and to maintain motivation to connect despite the risk of rejection. 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.

    International Nuclear Information System (INIS)

    A general description is made of clay as a geochemical medium, including a rapid review of the principal mineralogic data characterizing typical clay minerals, whereafter a description follows of the formation of geologic clay deposits. Two examples are used as illustration: the Boom clay formation at the Nuclear Center of Mol in Belgium and the marly clay layer at the Trisaia Nuclear Research Center in Italy. The principal physico-chemical and hydrogeologic properties of clays e.g. permeability and pore water composition are discussed in some detail due to their importance in assessing clay layers as host rock. Ion exchange of clays is reviewed with particular emphasis on the distribution coefficients, the diffusion coefficient and the migration parameters of radionuclides. Specific data relating to the Boom clay are commented in connection to the required conditioning techniques. The influence of heat on clay is shortly addressed and data are given of the heat transfer coefficients found in Belgium and Italy

  19. Moment formation in solids

    International Nuclear Information System (INIS)

    The problem of moment formation in metallic systems lies at the interface of localized and itinerant magnetism. The phenomena observed correspond to destruction rather than to formation of spin-correlations. They give rise to the progression from localized ground states through Kondo and mixed-valence behavior to itinerant magnetic or non-magnetic systems. Somewhere in the progression superconductivity can occur in the presence of f-moments. This conference presents information on the following topics: neuron inelastic scattering as a probe of moments in metallic systems; cyclotron resonance and relaxation of hot charge carriers; orbital effects in actinide systems; theory of elementary excitations in intermediate valence materials: phenomena involving magnetic moment suppresion; and superconducting ground state of a strongly interacting electron system: UBe13

    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.

    Czirok, Andras; Little, Charles D

    2012-06-01

    Vasculogenesis, the assembly of the first vascular network, is an intriguing developmental process that yields the first functional organ system of the embryo. In addition to being a fundamental part of embryonic development, vasculogenic processes also have medical importance. To explain the organizational principles behind vascular patterning, we must understand how morphogenesis of tissue level structures can be controlled through cell behavior patterns that, in turn, are determined by biochemical signal transduction processes. Mathematical analyses and computer simulations can help conceptualize how to bridge organizational levels and thus help in evaluating hypotheses regarding the formation of vascular networks. Here, we discuss the ideas that have been proposed to explain the formation of the first vascular pattern: cell motility guided by extracellular matrix alignment (contact guidance), chemotaxis guided by paracrine and autocrine morphogens, and sprouting guided by cell-cell contacts.

    Sunlight is the ultimate driver of biosynthesis but photochemical steps late in biosynthetic pathways are very rare. They appear to play a role in the formation of certain furanocembranoids isolated from Caribbean corals. One of these compounds, intricarene, has been suspected to arise from an intramolecular 1,3-dipolar cycloaddition involving an oxidopyrylium. Here we show, by a combination of experiments and theory, that the oxidopyrylium forms under photochemical conditions and that its cycloaddition occurs via a triplet state. The formation of a complex by-product can be rationalized by another photochemical step that involves a conical intersection. Our work raises the question whether intricarene is biosynthesized in the natural habitat of the corals or is an artefact formed during workup. It also demonstrates that the determination of exact irradiation spectra, in combination with quantum chemical calculations, enables the rationalization of complex reaction pathways that involve multiple excited states.

  4. 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)

    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....

  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.

    Layer formation in a thermally destabilized fluid with stable density gradient has been observed in laboratory experiments and has been proposed as a mechanism for mixing molecular weight in late stages of stellar evolution in regions which are unstable to semiconvection. It is not yet known whether such layers can exist in a very low viscosity fluid: this work undertakes to address that question. Layering is simulated numerically both at high Prandtl number (relevant to the laboratory) in or...

  18. 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

  1. Unemployment and Household formation

    OpenAIRE

    Ebrahim, Amina; Woolard, Ingrid; Leibbrandt, Murray

    2013-01-01

    In comparison to other continents, Africa has received little scholarly attention with regard to household composition. Household composition is endogenous to a variety of welfare issues and little is understood about the determinants of this composition. Understanding the household composition and formation decision may improve our understanding of how the unemployed gain access to resources and how household composition could provide a safety net to the unemployed. However, increasingly, mo...

  2. THE ALLIANCE FORMATION PROCESS

    OpenAIRE

    Whipple, Judith M.; Frankel, Robert

    1998-01-01

    While interest in developing strategic alliances within the food system continues to increase, there remains considerable risk when firms adopt such a cooperative strategy. The risk is due in part to the lack of concrete guidelines that illustrate the steps or stages of alliance development and the important strategic and operational decisions required at each stage. The existence of such guidelines would facilitate alliance formation and enable managers and researchers to better understand a...

    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.

  4. Mars brine formation experiment

    Evaporites, particularly carbonates, nitrates, and sulfates, may be major sinks of volatiles scavenged from the martian atmosphere. Mars is thought to have once had a denser, warmer atmosphere that permitted the presence of liquid surface water. The conversion of atmospheric CO2 into carbonate is hypothesized to have degraded the martian climate to its present state of a generally subfreezing, desiccated desert. The rate for such a conversion under martian conditions is poorly known, so the time scale of climate degradation by this process cannot be easily evaluated. If some models are correct, carbonate formation may have been fast at geological time scales. The experiments of Booth and Kieffer also imply fast (10(exp 6) - 10(exp 7) yr) removal of the missing CO2 inventory, estimated to be 1 - 5 bar, by means of carbonate formation. The timing of formation of many of the fluvial features observed on Mars is, in large part, dependent on when and how fast the atmosphere changed. A knowledge of the rate at which carbonates and nitrates formed is also essential for assessing the probability that life, or its chemical precursors, could have developed on Mars. No previous experiments have quantitatively evaluated the rate of solution for a suite of mobile anions and cations from unaltered minerals and atmospheric gases into liquid water under Mars-like conditions. Such experiments are the focus of this task.

  5. Cosmic Star Formation History

    CERN Document Server

    Madau, Piero

    2014-01-01

    Over the last decade and a half, an avalanche of new data from multiwavelength imaging and spectroscopic surveys has revolutionized our view of galaxy formation and evolution. Making sense of it all and fitting it together into a coherent picture remains one of astronomy's great challenges. Here we review the range of complementary techniques and theoretical tools that are allowing astronomers to map the cosmic history of star formation, heavy element production, and reionization of the universe from the cosmic "dark ages" to the present epoch. A consistent picture is emerging from modern galaxy surveys, whereby the star formation rate density peaked about 3.5 Gyr after the Big Bang, at redshift 1.9, and declined exponentially at later times, with an e-folding timescale of 3.9 Gyr. Half of the stellar mass observed today was formed before redshift 1.3. Less than 1% of today's stars formed during the epoch of reionization, at redshift greater than 6. Under the simple assumption of a universal initial mass func...

    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...

    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.

    2014-04-01

    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.

  20. 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

  1. Compact toroid formation experiments

    International Nuclear Information System (INIS)

    We present the design and experimental performance of a compact toroid (CT) formation experiment. The device has co-axial electrode diameters of 0.9 m (inner) and 1.25 m (outer), and an electrode length of ∼ 1.2 m, including an expansion/drift section. The CT is formed by a 0.1--0.2 Tesla initial radial magnetic field embedded co-axial puff gas discharge. The gas puff is injected with an array of 60 pulsed solenoid driven fast valves. The formation discharge is driven by a 108 microfarad, 40 to 100 KV, 86 to 540 kilojoule 2 to 5 megamp capacitor discharge with ∼ 20 nanohenry initial total discharge inductance. The hardware includes transmission line connections for a Shiva Star (1300 microfarad, up to 120 KV, 0.4 megajoule) capacitor bank driven acceleration discharge. Experimental measurements include current, voltage; azimuthal, radial and axial magnetic field at numerous location; fast photography, optical spectroscopy; microwave, CO2 laser, and He-Ne laser interferometry. Auxiliary experiments include Penning ionization gauge, pressure probe, and breakdown gas trigger diagnostics of gas injection, and Hall probe measurements of magnetic field injection

  5. 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.

  6. DUST FORMATION IN MACRONOVAE

    International Nuclear Information System (INIS)

    We examine dust formation in macronovae (as known as kilonovae), which are the bright ejecta of neutron star binary mergers and one of the leading sites of r-process nucleosynthesis. In light of information about the first macronova candidate associated with GRB 130603B, we find that dust grains of r-process elements have difficulty forming because of the low number density of the r-process atoms, while carbon or elements lighter than iron can condense into dust if they are abundant. Dust grains absorb emission from ejecta with an opacity even greater than that of the r-process elements, and re-emit photons at infrared wavelengths. Such dust emission can potentially account for macronovae without r-process nucleosynthesis as an alternative model. This dust scenario predicts a spectrum with fewer features than the r-process model and day-scale optical-to-ultraviolet emission

  7. Standardizing exchange formats

    An international network of co-operating data centres is described who maintain identical data bases which are simultaneously updated by an agreed data exchange procedure. The agreement covers ''data exchange formats'' which are compatible to the centres' internal data storage and retrieval systems which remain different, optimized at each centre to the available computer facilities and to the needs of the data users. Essential condition for the data exchange is an agreement on common procedures for the data exchange is an agreement on common procedures for the data compilation, including critical data analysis and validation. The systems described (''EXFOR'', ''ENDF'', ''CINDA'') are used for ''nuclear reaction data'', but the principles used for data compilation and exchange should be valid also for other data types.

    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 ...

  9. 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).

    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.

    Schneider, A S; Hughto, J; Berry, D K

    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...

  15. Recipes for planet formation

    Meyer, Michael R.

    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.

    Models of sprite formation for positive cloud-to-ground lightning strokes predict both downward (positive), and upward (negative) propagating streamers. Previous high speed camera observations of sprites are generally consistent with these predictions, but have been unable to resolve the temporal formation of the streamers due to frame rates limited to a few thousand frames per second. We report observations made during the evening of 9 July 2005 at 10,000 frames per second, with the image intensifier gated to 50 microseconds per frame. These observations often show the streamer head to be a bead-like structure propagating downward at approximately 7x106 m/s for 1,500 microseconds. The bead is followed by a dark region, and the main emissions from the sprite column are delayed ~800 microseconds after the passage of the streamer head. There are also "beads" which clearly propagate upward. Some events appear to be very similar to laboratory images of time resolved streamer zones. We interpret these observations in terms of positive/negative streamers. We see evidence for branching of the streamer tips in several cases, as well as evidence of upward propagating streamers transitioning into a more diffuse emission. Previous work (Pasko and Stenbaek-Nielsen, GRL 29(10), 2002) indicates this transition region has a lower border at an altitude when the dielectric relaxation time scale equals the time scale for an individual electron to develop into a streamer, and an upper border when the dielectric relaxation time scale roughly equals the dissociative attachment time scale. The present observations appear to be broadly consistent with this interpretation.

    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.

  19. Modeling Formation of Globular Clusters: Beacons of Galactic Star Formation

    CERN Document Server

    Gnedin, Oleg Y

    2010-01-01

    Modern hydrodynamic simulations of galaxy formation are able to predict accurately the rates and locations of the assembly of giant molecular clouds in early galaxies. 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.

Formation in situ from disks with radial mass surface density, $\\Sigma$, profiles similar to the minimum mass solar nebula (MMSN) but boosted in normalization by factors $\\gtrsim 10$ has been suggested. We propose that a more natural way to create these planets in the inner disk is formation sequentially from the inside-out via creation of successive gravitationally unstable rings fed from a ...

    The question of whether alliance formation contributes to peace or to war is analyzed for the modern Great Power system over the last 500 years. It is found that for none of the last five centuries has alliance formation been correlated (tau-b) with war involving the Great Powers, and has often been correlated with peace. Furthermore, disproportionately few wars have been preceded by alliance formation (compared to random probability models), suggesting that alliances are not among the more i...

    International standards for lexicon formats are in preparation. To a certain extent, the proposed formats converge with prior results of standardization projects. However, their adequacy for (i) lexicon management and (ii) lexicon-driven applications have been little debated in the past, nor are they as a part of the present standardization effort. We examine these issues. IGM has developed XML formats compatible with the emerging international standards, and we report experimental results on large-coverage lexica.

    2015-01-01

    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.

    Er, Jenn Wei; Zhao, Bing; Law, Adrian W. K.; Adams, E. Eric

    2014-11-01

    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.

  9. The formation of Pangea

    Stampfli, G. M.; Hochard, C.; Vérard, C.; Wilhem, C.; vonRaumer, J.

    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

    2010-11-01

    Full Text Available Abstract Background Although solid surface-associated biofilm development of S. oneidensis has been extensively studied in recent years, pellicles formed at the air-liquid interface are largely overlooked. The goal of this work was to understand basic requirements and mechanism of pellicle formation in S. oneidensis. Results We demonstrated that pellicle formation can be completed when oxygen and certain cations were present. Ca(II, Mn(II, Cu(II, and Zn(II were essential for the process evidenced by fully rescuing pellicle formation of S. oneidensis from the EDTA treatment while Mg (II, Fe(II, and Fe(III were much less effective. Proteins rather than DNA were crucial in pellicle formation and the major exopolysaccharides may be rich in mannose. Mutational analysis revealed that flagella were not required for pellicle formation but flagellum-less mutants delayed pellicle development substantially, likely due to reduced growth in static media. The analysis also demonstrated that AggA type I secretion system was essential in formation of pellicles but not of solid surface-associated biofilms in S. oneidensis. Conclusion This systematic characterization of pellicle formation shed lights on our understanding of biofilm formation in S. oneidensis and indicated that the pellicle may serve as a good research model for studying bacterial communities.

  18. Modes of clustered star formation

    CERN Document Server

    Pfalzner, S; Olczak, C

    2012-01-01

    The realization that most stars form in clusters, raises the question of whether star/planet formation are influenced by the cluster environment. The stellar density in the most prevalent clusters is the key factor here. Whether dominant modes of clustered star formation exist is a fundamental question. Using near-neighbour searches in young clusters Bressert et al. (2010) claim this not to be the case and conclude that star formation is continuous from isolated to densely clustered. We investigate under which conditions near-neighbour searches can distinguish between different modes of clustered star formation. Near-neighbour searches are performed for model star clusters investigating the influence of the combination of different cluster modes, observational biases, and types of diagnostic and find that the cluster density profile, the relative sample sizes, limitations in observations and the choice of diagnostic method decides whether modelled modes of clustered star formation are detected. For centrally ...

    We have summed up our investigations performed in 1970--1993. 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.

    Based on the recently proposed Interactive Model of Identity Formation, we examine how top-down deductive and bottom-up inductive identity formations influence intentions and behaviour in multiparty negotiations. Results show that a shared identity can be deduced from the social context through recognition of superordinate similarities. However, shared identities can also be induced by intragroup processes in which individuals get acquainted with one another on an interpersonal basis. Both top-down and bottom-up processes led to the formation of a sense of shared identity, and this in turn exerted a positive influence on behavioural intentions and actual behaviour in multiparty negotiations.

  7. 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...

    2011-07-01

    Full Text Available The development of secondary distant organ and lymph node metastasis has an extraordinary impact on the prognosis of patients with solid cancer. In most cases the advent of metastatic growth represents the turning point from a local, potentially curable, disease to a systemic non-curable situation. As a highly regulated process, metastasis formation follows a distinct, non-random pattern characteristic for each tumor entity. Metastasis formation and strategies to prevent this lethal event in the progression of cancer is of fundamental interest for cancer science and patient care. In this special issue of Cancers, papers highlighting cellular mechanisms of metastasis formation, genetic and epigenetic aspects associated with organ and tumor specific metastasis formation, as well as papers outlining experimental and clinical therapeutic concepts for anti-metastatic treatment are included.

    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...

    2006-01-01

    The old dream of integrating into one the study of micro and macrocosmos is now a reality. Cosmology, astrophysics, and particle physics intersect in a scenario (but still not a theory) of cosmic structure formation and evolution called Lambda Cold Dark Matter (LCDM) model. This scenario emerged mainly to explain the origin of galaxies. In these lecture notes, I first present a review of the main galaxy properties, highlighting the questions that any theory of galaxy formation should explain. Then, the cosmological framework and the main aspects of primordial perturbation generation and evolution are pedagogically detached. Next, I focus on the ``dark side'' of galaxy formation, presenting a review on LCDM halo assembling and properties, and on the main candidates for non-baryonic dark matter. It is shown how the nature of elemental particles can influence on the features of galaxies and their systems. Finally, the complex processes of baryon dissipation inside the non-linearly evolving CDM halos, formation o...

  14. Robust Decentralized Formation Flight Control

    Directory of Open Access Journals (Sweden)

    2011-01-01

    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.

  17. 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.

    The manner the galaxy accretes matter along with the star formation rates at different epochs, influence the evolution of the stable isotopic inventories of the galaxy. A detailed analysis is presented here to study the dependence of the galactic chemical evolution on the accretion scenario of the galaxy along with the star formation rate during the early accretionary phase of the galactic thick disk and thin disk. Our results indicate that a rapid early accretion of the galaxy during the for...

    This thesis investigates the dynamics of European identity formation with the purpose of contributing to our understanding of the circumstances affecting the potential for collective identity formation within the EU. Theoretically the thesis draws upon self-categorization theory according to which collective identities take form on the basis of a very basic human need for a social identity. As such collective identities emerge when individual’s social identity are activated. In such situatio...

    Meyer-Ortmanns, Hildegard

    We study ghetto formation in a population with natives and immigrants in the framework of the two-dimensional Ising-model with Kawasaki-exchange dynamics. It is the phase structure of the Ising model, the integration speed and the immigration rate which determine whether ghetto formation between natives and immigrants can be avoided or not. Our simulations are performed in- and out-of-equilibrium.

    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.

  7. An historical sketch of the American population control movement.

    Science.gov (United States)

    Mass, B

    1974-01-01

    The fundamental premises and historical development of the American population control movement are critically examined from the Marxist viewpoint. It is initially shown how the Malthusian theories of population growth became interwoven with those of the eugenics movement during the first 4 decades of the 20th century. After World War II, the concern of eugenicists with race betterment and with halting the growth in numbers of the "unfit" was superseded by claims that the world was gravely menaced by a "population explosion." Subsequently, it is shown how American financiers and industrialists became leading figures of the "Population Establishment" and promoted private and public funding for support of population control activities. The uneven growth in the 1950's and the rapid growth in the 1960's of United States' efforts to promote domestic and international family planning activities are described at length. Activities of UN agencies and of United States Government agencies, particularly the activities of the Agency for International Development, are emphasized. A description of events connected with World Population Year notes the opposition of many developing countries to what they regard as an overemphasis upon birth control divorced from broad programs of social and economic development. The alleged economic exploitation of capitalism is regarded as a fundamental roadblock to intelligent family planning. Thus, talk of the population bomb merely masks the need to eliminate capitalism and proceed with an equitable distribution of the world's resources. PMID:4463172

  8. A framework and two sketches concerning psychoanalytical training and practice.

    Science.gov (United States)

    Mandelbaum, Belinda

    2003-02-01

    The author discusses the mode of knowledge production in psychoanalysis based on a reflection on the psychoanalytical education and its relationship to clinical practice. She points out that there is a risk in a form of clinical activity found in our education, which, under the fascination of the analyst's power of operating in the metaphorical domain of words, loses sight of the material dimension of the clinical action. In other words, this form of clinical activity loses sight of the meeting with another human being, of the repertoire of theories and experiences that informs this action and the patient's and the analyst's concrete life situation. The author highlights the role of writing as a privileged way of dealing with the material and immaterial facts that constitute the clinical action and reflects on some of the forces that structure nowadays the reception of knowledge production inside the psychoanalytical field. She uses the notion of 'minor literature', by Franz Kafka, to express the possibility that a live circuit of writings exchanged among psychoanalysts can offer to an interchange of experiences and ideas that is the live expression of the history of the psychoanalytical groups. A clinical session is presented in order to promote considerations about the psychoanalytical education, theory and practice. PMID:12639266

  9. CHINA AND THE SOCIALIST TRANSITION - A BRIEF SKETCH

    Directory of Open Access Journals (Sweden)

    Luís Carapinha

    2014-06-01

    Full Text Available The troubled course of the revolutionary process of building socialism in China reveals a gradual reorientation of revolutionary energies to the "technical tasks", focused on economic development and increase of productive forces. The theoretical and practical reframing of Chinese socialist transition acquires a qualitative dimension with the proclamation of the Reform and Opening policy and the recognition of the historical phase that the Communist Party of China, since Deng Xiaoping, defined as the primary stage of socialism. The economic reformulation stresses the issue of the use of market instruments in the process of socialist transition in China, establishing a parallel with the pioneering experience of Soviet NEP. The socialist market economy in China corresponds to a model of mixed economy, in which public ownership and the State hold the commanding heights of the economy, and the integration into the world economy is a key lever. This reality that does not set as granted a return of China to the dominance of capitalism. At the same time, the inevitable clash between the dynamics of two conflicting economic systems – socialism and capitalism – raises to the CCP and the Chinese proletariat the theoretical and practical requirement of safeguarding a re-updated class perspective.

  15. Scenario sketches for Nordic H{sub 2} Energy introduction

    Energy Technology Data Exchange (ETDEWEB)

    Eriksson, E.A. [FOI Defence Analysis, Stockholm (Sweden)

    2003-12-01

    This report departs from a set of external scenarios setting the context for a Nordic H2 energy introduction, and a set of H2 related socio-technical visions, amended and assessed by an expert workshop (Stockholm, August 2003). Based on this it attempts to outline a Nordic policy strategy aiming at as internationally leading a position in H2 energy as reasonable under different external conditions. Then this putative policy commitment is set against the nine context scenarios (three alternative stage-setting developments in the 2003-15 time frame and for each of these three alternative, more specifically energy-relevant developments for 2015-30). The result is that the prospects for H2 energy introduction differ widely across future developments. However, a policy strategy that combines RTD centres of excellence and large-scale socio-technical experimentation (e.g., demos and pilots) with polices that stimulate entrepreneurs to exploit niche markets and technology foresight and the like, not least to achieve bottom-up coordination. While strong policy interventions for H2 energy are conceivable under certain sets of external conditions, more typically it will have to win out in some type of competition. Therefore it is important that energy innovation policies be reasonably unbiased with respect to different energy forms rather than trying to prematurely pick winners. (au)

  16. Changing Paradigms: A Sketch for Sustainable Wellbeing and Ecosocial Policy

    Directory of Open Access Journals (Sweden)

    Tuuli Hirvilammi

    2014-04-01

    Full Text Available We live in the Anthropocene era, where human action has an unforeseen impact on global ecosystems. This is visible, for instance, in climate change, in the loss of biodiversity and in the acidification of the oceans. Little attention is given to the fact that the Anthropocene is related to anthropocentric thinking that also guides our policies. Therefore, we argue that ecologically and socially sustainable policies will not be achieved by incidental policy measures alone, but a change of paradigm is needed. In our article, we lay out the tenets of a relational paradigm resting on holistic thinking and deep ecology. On the basis of this paradigm, the principles, conceptions and goals specific to any given policy can be formulated, giving them a common ground. In this article, we apply the relational paradigm to social policy in order to contribute to the quest for sustainable wellbeing in the overconsuming welfare states. Here, we formulate a multidimensional and relational conception of wellbeing, the HDLB-model (Having-Doing-Loving-Being, which is a modification of sociologist Erik Allardt’s theory. We illustrate how this model could provide the foundation of a sustainable ecosocial policy.

  2. A sketch of language history in the Korean Peninsula.

    Directory of Open Access Journals (Sweden)

    Sean Lee

    Full Text Available Among 7100 languages spoken on Earth, the Koreanic language is the 13th largest, with about 77 million speakers in and around the Korean Peninsula. In comparison to other languages of similar size, however, surprisingly little is known about the evolution of the Koreanic language. This is mainly due to two reasons. The first reason is that the genealogical relationship of the Koreanic to other neighboring languages remains uncertain, and thus inference from the linguistic comparative method provides only provisional evidence. The second reason is that, as the ancestral Koreanic speakers lacked their own writing system until around 500 years ago, there are scant historical materials to peer into the past, except for those preserved in Sinitic characters that we have no straightforward way of interpreting. Here I attempt to overcome these disadvantages and shed some light on the linguistic history of the Korean Peninsula, by analyzing the internal variation of the Koreanic language with methods adopted from evolutionary biology. The preliminary results presented here suggest that the evolutionary history of the Koreanic language is characterized by a weak hierarchical structure, and intensive gene/culture flows within the Korean Peninsula seem to have promoted linguistic homogeneity among the Koreanic variants. Despite the gene/culture flows, however, there are still three detectable linguistic barriers in the Korean Peninsula that appear to have been shaped by geographical features such as mountains, elevated areas, and ocean. I discuss these findings in an inclusive manner to lay the groundwork for future studies.

    The present paper is about a preliminary study of the georesources (water and raw materials for construction) of Niamey city (Niger). Such research is part of an UNICOO project (funded by the University of Turin) and connected to the Edulink Cooperation Project (R.U.S.S.A.D.E.), a multidisciplinary project between Italy, Niger, Burquina Faso and Tchad funded on ACP- EU cooperation program in Higher Education. The main goals are the qualitative and quantitative characterization of the surface water and groundwater, and of aggregates (exploited in sands and gravel quarries). More specifically, at the beginning of the study there was a census of wells and quarries in the Niamey area, with a consequent sampling survey (surface water and groundwater sampling and aggregate sampling). After that, an in situ characterization was set: measure of piezometric levels in wells, water characterization (pH, electrolytic conductivity, temperature, nitrate and ammonia concentration) and an in situ evaluation of the quarrying techniques and quarry exploitation (present and old quarries). The samples were analyzed in Earth Science Dep. (UNITO) to evaluate the content of the main anions and cations (chemical analysis of sampled water) and the size distribution of the materials coming from the investigated quarries. Schematic reports of wells and quarries (location and features) were produced with the support of a Geodatabase with all available data. Geomatics instruments and methodologies (Geotagged Photos, Digital Mapping, GNSS Survey, Satellite Multitemporal Maps,) were basic starting point for the field data collection and a fundamental aid for data arrangement and final dissemination. The present study evidenced the actual condition of surface water and groundwater, also highlighting local phenomena of pollution. Nitrate in groundwater, i.e., showed locally concentration up to 5 times the WHO limit (50 mg/L). Thanks to the local quarry survey it was possible to evaluate how the open quarries works (open air yards, exploited by means of hand shovels and basic sieves) and what is the destination of the closed one (most of time the closed quarries are abandoned, not monitored and used as dumping areas, increasing the possibility of groundwater contamination). The safety condition of workers are very scarce: no protection devices, hard works and not safe yards (narrow tunnels, dug by hand and without protections). A sustainable management of natural resources and an appropriate environmental recovery are recommended, in order to prevent pollution and environmental deterioration. All the information arising from the present work are useful for local decision makers to enhance Niamey georesources management. At last, the information on water quality and quantity is fundamental in a wider perspective of food security and for life quality improvement. A final GIS project was prepared in order to have a good overview of the data and for dissemination purposes.

    2011-01-01

    We present an application of interactive global illumination and spatially augmented reality to architectural daylight modeling that allows designers to explore alternative designs and new technologies for improving the sustainability of their buildings. Images of a model in the real world, captured by a camera above the scene, are processed to construct a virtual 3D model. To achieve interactive rendering rates, we use a hybrid rendering technique, leveraging radiosity to simulate the interreflectance between diffuse patches and shadow volumes to generate per-pixel direct illumination. The rendered images are then projected on the real model by four calibrated projectors to help users study the daylighting illumination. The virtual heliodon is a physical design environment in which multiple designers, a designer and a client, or a teacher and students can gather to experience animated visualizations of the natural illumination within a proposed design by controlling the time of day, season, and climate. Furthermore, participants may interactively redesign the geometry and materials of the space by manipulating physical design elements and see the updated lighting simulation. PMID:21071786

  7. A systematic approach to sketch Bethe-Salpeter equation

    CERN Document Server

    Qin, Si-xue

    2016-01-01

    To study meson properties, one needs to solve the gap equation for the quark propagator and the Bethe-Salpeter (BS) equation for the meson wavefunction, self-consistently. The gluon propagator, the quark-gluon vertex, and the quark--anti-quark scattering kernel are key pieces to solve those equations. Predicted by lattice-QCD and Dyson-Schwinger analyses of QCD's gauge sector, gluons are non-perturbatively massive. In the matter sector, the modeled gluon propagator which can produce a veracious description of meson properties needs to possess a mass scale, accordingly. Solving the well-known longitudinal Ward-Green-Takahashi identities (WGTIs) and the less-known transverse counterparts together, one obtains a nontrivial solution which can shed light on the structure of the quark-gluon vertex. It is highlighted that the phenomenologically proposed anomalous chromomagnetic moment (ACM) vertex originates from the QCD Lagrangian symmetries and its strength is proportional to the magnitude of dynamical chiral symm...

    Energy Technology Data Exchange (ETDEWEB)

    Berenstein, D. [Physics Department, University of California, Santa Barbara, CA 93106 (United States)

    2014-09-11

    In this paper three notions of emergent geometry arising from the study of gauge/gravity duals are discussed. The unifying theme behind these notions of emergent geometry is that one can derive properties of the effective action of a probe or excitation around some configuration in gauge theory which can be argued to be localized at a particular position in the gravity dual, and match this description to various degrees of accuracy in the gravity dual. The three examples discussed are giant gravitons in AdS{sub 5} x S{sup 5}, open strings stretching between these giants and the probe dynamics of a D0 brane in the presence of a thermal matrix configuration of the BFSS matrix model.

    Methods for treating a tar sands formation are described herein. The tar sands formation may have one or more karsted zones. Methods may include providing heat from one or more heaters to one or more karsted zones of the tar sands formation to mobilize fluids in the formation. At least some of the mobilized fluids may be produced from the formation.

    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
