A graph rewriting programming language for graph drawing
Rodgers, Peter
1998-01-01
This paper describes Grrr, a prototype visual graph drawing tool. Previously there were no visual languages for programming graph drawing algorithms despite the inherently visual nature of the process. The languages which gave a diagrammatic view of graphs were not computationally complete and so could not be used to implement complex graph drawing algorithms. Hence current graph drawing tools are all text based. Recent developments in graph rewriting systems have produced computationally com...

Layered Graph Drawing for Visualizing Evaluation Structures.
Onoue, Yosuke; Kukimoto, Nobuyuki; Sakamoto, Naohisa; Misue, Kazuo; Koyamada, Koji
2017-01-01
An evaluation structure is a hierarchical structure of human cognition extracted from interviews based on the evaluation grid method. An evaluation structure can be defined as a directed acyclic graph (DAG). The authors propose a layer-assignment method that is part of the Sugiyama framework, a popular method for drawing DAGs, to satisfy the requirements for drawing evaluation structures. Their evaluations demonstrate that the layered graph drawing produced by the proposed layer-assignment method is preferred by users and aids in the understanding of evaluation structures.

Drawing a baseline in aesthetic quality assessment
Rubio, Fernando; Flores, M. Julia; Puerta, Jose M.
2018-04-01
Aesthetic classification of images is an inherently subjective task. There does not exist a validated collection of images/photographs labeled as having good or bad quality from experts. Nowadays, the closest approximation to that is to use databases of photos where a group of users rate each image. Hence, there is not a unique good/bad label but a rating distribution given by users voting. Due to this peculiarity, it is not possible to state the problem of binary aesthetic supervised classification in such a direct mode as other Computer Vision tasks. Recent literature follows an approach where researchers utilize the average rates from the users for each image, and they establish an arbitrary threshold to determine their class or label. In this way, images above the threshold are considered of good quality, while images below the threshold are seen as bad quality. This paper analyzes current literature, and it reviews those attributes able to represent an image, differentiating into three families: specific, general and deep features. Among those which have been proved more competitive, we have selected a representative subset, being our main goal to establish a clear experimental framework. Finally, once features were selected, we have used them for the full AVA dataset. We have to remark that to perform validation we report not only accuracy values, which is not that informative in this case, but also, metrics able to evaluate classification power within imbalanced datasets. We have conducted a series of experiments so that distinct well-known classifiers are learned from data. Like that, this paper provides what we could consider valuable and valid baseline results for the given problem.
A New Graph Drawing Scheme for Social Network

2014-01-01
visualization is employed to extract the potential information from the large scale of social network data and present the information briefly as visualized graphs. In the process of information visualization, graph drawing is a crucial part. In this paper, we study the graph layout algorithms and propose a new graph drawing scheme combining multilevel and single-level drawing approaches, including the graph division method based on communities and refining approach based on partitioning strategy. Besides, we compare the effectiveness of our scheme and FM3 in experiments. The experiment results show that our scheme can achieve a clearer diagram and effectively extract the community structure of the social network to be applied to drawing schemes.
Graph-drawing algorithms geometries versus molecular mechanics in fullereness
Kaufman, M.; Pisanski, T.; Lukman, D.; Borštnik, B.; Graovac, A.
1996-09-01
The algorithms of Kamada-Kawai (KK) and Fruchterman-Reingold (FR) have been recently generalized (Pisanski et al., Croat. Chem. Acta 68 (1995) 283) in order to draw molecular graphs in three-dimensional space. The quality of KK and FR geometries is studied here by comparing them with the molecular mechanics (MM) and the adjacency matrix eigenvectors (AME) algorithm geometries. In order to compare different layouts of the same molecule, an appropriate method has been developed. Its application to a series of experimentally detected fullerenes indicates that the KK, FR and AME algorithms are able to reproduce plausible molecular geometries.

In this paper, we propose a syntactic pattern recognition method for non-schematic drawings, based on a new attributed graph grammar with flexible embedding. In our graph grammar, the embedding rule permits the nodes of a guest graph to be arbitrarily connected with the nodes of a host graph. The ambiguity caused by this flexible embedding is controlled with the evaluation of synthesized attributes and the check of context sensitivity. To integrate parsing with the synthesized attribute evaluation and the context sensitivity check, we also develop a bottom up parsing algorithm.

Subprogram STDPL for standard graph drawing of two-dimensional data
International Nuclear Information System (INIS)
Fujimura, Toichiro
1977-05-01
The subroutine STDPL has been developed for drawing the graphs of data. The data should have two components, and the graphs are drawn on x-y plane using refined parameters. A functional subroutine package, F-Series, was also developed by combining the basic plotter subroutines, which is employed in STDPL. Visualization of the data is important in grasping trend of the results obtained by experiment or calculation. However, plotting them by use of the basic subroutines alone is laborious and tends to give errors. The STDPL is designed to detect input-parameter errors and correct them as much as possible to continue the plotting. Some typical examples and FORTRAN list of the subroutines are also given. (auth.)
Toward Measuring Network Aesthetics Based on Symmetry

Zengqiang Chen
2017-05-01
Full Text Available In this exploratory paper, we discuss quantitative graph-theoretical measures of network aesthetics. Related work in this area has typically focused on geometrical features (e.g., line crossings or edge bendiness of drawings or visual representations of graphs which purportedly affect an observer’s perception. Here we take a very different approach, abandoning reliance on geometrical properties, and apply information-theoretic measures to abstract graphs and networks directly (rather than to their visual representaions as a means of capturing classical appreciation of structural symmetry. Examples are used solely to motivate the approach to measurement, and to elucidate our symmetry-based mathematical theory of network aesthetics.
Mechanical properties and aesthetics of FRP orthodontic wire fabricated by hot drawing.

1998-12-01
The FRP wires 0.5 mm in diameter with a multiple fiber structure were fabricated by drawing the fiber polymer complex at 250 degrees C for an esthetic, transparent orthodontic wire. Biocompatible CaO-P2O5-SiO2-Al2O3 (CPSA) glass fibers of 8-20 microm in diameter were oriented unidirectionally in the longitudinal direction in PMMA matrix. The mechanical properties were investigated by 3-point flexural test. The FRP wire showed sufficient strength and a very good elastic recovery after deformation. Young's modulus and the flexural load at deflection 1 mm were nearly independent of the fiber diameter and linearly increased with the fiber fraction. The dependence on fiber fraction obeys well the rule of mixture. This FRP wire could cover the range of strength corresponding to the conventional metal orthodontic wires from Ni-Ti used in the initial stage of orthodontic treatments to Co-Cr used in the final stage by changing the volume ratio of glass fibers with the same external diameter. The estheticity in external appearance was excellent. Thus the new FRP wire can satisfy both mechanical properties necessary for an orthodontic wire and enough estheticity, which was not possible for the conventional metal wire.

PLOT3D series of graphic codes (version 1 to 5) have been developed for drawing three dimensional graphs, maps, histograms and simple layout diagrams on monochrome or colour raster graphic terminal and plotter. Of these, PLOT3D Version-5 is an advanced code, equipped with several features that make it specially suitable for drawing 3D maps, multicolour 3D and contour graphs, and 3D layout diagrams, in axonometric or perspective projection. Prior to drawing, graphic parameters that define orientation, magnification, smoothening, shading, colour-map, etc. of the figure can be selected interactively by means of simple commands on the user terminal, or by reading those commands from an input data file. This code requires linking with any one of three supporting libraries: PLOT 10 TCS, PLOT 10 IGL, and CALCOMP, and the figure can be plotted in single colour, or displayed in single or multiple colours depending upon the type of library support and output device. Furthermore, this code can also be used to plot left and right eye view projections of 3D figure for composing a stereoscopic image from them with the aid of a viewer. 14 figures. (author)

How might the psycho-social effects of chronic skin disease, its treatments (and discontents) be figuratively expressed in writing and painting? Does the art reveal common denominators in experience and representation? If so, how do we understand the cryptic language of these expressions? By examining the works of artists with chronic skin diseases--John Updike, Elizabeth Bishop, and Zelda Fitzgerald--some common features can be noted. Chronically broken skin can fracture the ego or self-perception, resulting in a disturbed body image, which leads to personality disorders and co-morbid affective disorders such as anxiety and depression. The vertiginous feeling that results can be noted in the paradoxical characters, figures, and psyches portrayed in the works of these artists. This essay will examine the more specific ways in which artists disclose and/or conceal their experiences and the particular ways in which these manifest in their works. While certain nuances exist, the common denominators give us a starting point for developing an eczema aesthetic, a code for interpreting the ways in which artists' experiences with skin disease manifest in their works.

Full Text Available Being a linguistic phenomenon, poetry is marked by the defamilarization of language in a poetic discourse there is an aesthetic distortion of the normal codes, in which the aesthetic value is the most prominent function of the poetic texture . This study is a new adventure in correlating linguistics to aesthetics by and through the so-called approach Aesthetic stylistics( As. Aesthetic stylistics is the application of the theory of beauty to the intentionally violated components in literary text. It proceeds with the hypothesis that John Keats's Ode on a Grecian Urn and Kabbani's Maritime Poem are disinterested poetic experiences which create ecstatic responses to the reader's awareness, therefore, the judgment of the reader's taste is aesthetic. The study aims at highlighting the stylistic-aesthetic factors which generate the judgment of taste. While drawing heavily on the aestheticism of the Prague Linguistic Circle and Halliday's Functional Linguistics (FL, or what has come to be called the Traditional European Functionalism, the study will analyze Keats' Ode and Kabbani's poem in terms of Kant's Kritik der Urteilstraft, KdU. The two circles of the linguistic description and aesthetic interpretation will be internally interlinked to create the coherence of the stylistic process. The study consists of an introduction, two parts, one in theory and the other in analysis; it is eventually rounded up with concluding remarks elicited from the semiotic quest.

In painting art and photography have been happening genres and styles that have adopted criteria of one or another discipline. When photography became independent from painting as an artistic discipline, its relationship to the architecture affected both the acceptance of its stylistic canon and the broadcast area. With technological development and the emergence of the new concept of digital imaging, it has become an indispensable tool in the whole process of contemporary architecture, which should not contaminate the true sense of the architectural drawing.

Theoretic standings behind magnetic force-directed approach are stated together with review on how particular features of respective algorithms in combination with appropriate visual techniques are especially suitable for improved processing and presenting of knowledge that is captured in form of graphs. The complexity of retrieving multi-attributed information within the proposed approach is handled with dedicated tools, such as selective attraction of nodes to MFE (Magnetic Force Emitter based on search criteria, localization of POI (Point of Interest regions, graph node anchoring, etc. Implicit compatibility of aforementioned tools with interactive nature of data exploration is distinguished. Description of case study, based on bibliometric network analysis is given, which is followed by the review of existing related works in this field. Conclusions are made and further studies in the field of visualization of multi-attributed graphs are defined.

As the world around us is transformed into digitally enabled forms and processes, aesthetic strategies are required that articulate this underlying condition. A method for doing so involves a formal and conceptual strategy that is derived from collage, montage and assemblage. This triple "age" is termed "troiage", and it uses a style of computational apparency which articulates the edges of our current representational forms and processes as the semantic elements of culture. Each of these component aesthetics has previously had an important effect upon different areas of contemporary art and culture. Collage in painting, montage in film, assemblage in sculpture and architecture, are recombined via algorithmic methods, forefronting the structure of the algorithmic itself. The dynamic of the aesthetic is put into play by examining binary relationships such as: nature/culture, personal/public, U.S/Mexico, freedom/coercion, mediation/experience, etc. Through this process, the pervasiveness of common algorithmic approaches across cultural and social operations is revealed. This aesthetic is used in the project "The Scalable City" in which a virtual urban landscape is created by users interacting with data taken from the physical world in the form of different photographic techniques. This data is transformed by algorithmic methods which have previously been unfamiliar to the types of data that they are utilizing. The Scalable City project creates works across many media; such as prints, procedural animations, digital cinema and interactive 3D computer graphic installations.

The question of how to place psychoanalysis in relation to science has been debated since the beginning of psychoanalysis and continues to this day. The author argues that psychoanalysis is best viewed as a form of applied art (also termed applied aesthetics) in parallel to medicine as applied science. This postulate draws on a functional definition of modernity as involving the differentiation of the value spheres of science, art, and religion. The validity criteria for each of the value spheres are discussed. Freud is examined, drawing on Habermas, and seen to have erred by claiming that the psychoanalytic method is a form of science. Implications for clinical and metapsychological issues in psychoanalysis are discussed. © 2016 The Psychoanalytic Quarterly, Inc.

Art theorists, Carole Gray and Heather Delday (2010) pose the question, "What might be known through creative practice that could not be known by any other means?" As a visual artist with a doctorate degree in environmental planning from the TU-Berlin's Department of Soil Protection, I have long considered this question in my work and over the years contributed an active voice to discussions on research, education, and public engagement with soil and art and soil and culture in Germany and around the world. After presenting many other examples of artists' work at international scientific symposia, I would like to present examples of some of my own artistic practice with soil mapping and soil protection issues at the 2017 EGU. In combining methods of visual art, landscape analysis, and soil mapping, I have developed a practice called Aesthetic Cartography that employs sculptural techniques, object-making, installation and performance, printing and graphic design, as well as site analysis, data mining, and map reading and interpretation. Given my background in participatory planning practices, I also integrate small-group dialogic processes in the creation and implementation of my works. The projects making up the body of works in Aesthetic Cartography are mainly focused on urban issues, including: soil sealing, inner-city watershed management, creative brownfield use, rubble substrates and leachates, foraging and urban agriculture, and envisioning sustainable cities of the future. In the session SSS1.4 - Soil, Art, and Culture I will summarize project goals, materials and methods, venues and public contexts, elements of collaboration and participation, as well as target audiences involved in several projects of the Aesthetic Cartography series. The aim of the presentation is not to give a comprehensive answer to Gray and Delday's question above, but rather to share personal insights from a professional practice that merges artistic and scientific approaches to soil
An efficient algorithm for planar drawing of RNA structures with pseudoknots of any type.
Byun, Yanga; Han, Kyungsook
2016-06-01
An RNA pseudoknot is a tertiary structural element in which bases of a loop pair with complementary bases are outside the loop. A drawing of RNA secondary structures is a tree, but a drawing of RNA pseudoknots is a graph that has an inner cycle within a pseudoknot and possibly outer cycles formed between the pseudoknot and other structural elements. Visualizing a large-scale RNA structure with pseudoknots as a planar drawing is challenging because a planar drawing of an RNA structure requires both pseudoknots and an entire structure enclosing the pseudoknots to be embedded into a plane without overlapping or crossing. This paper presents an efficient heuristic algorithm for visualizing a pseudoknotted RNA structure as a planar drawing. The algorithm consists of several parts for finding crossing stems and page mapping the stems, for the layout of stem-loops and pseudoknots, and for overlap detection between structural elements and resolving it. Unlike previous algorithms, our algorithm generates a planar drawing for a large RNA structure with pseudoknots of any type and provides a bracket view of the structure. It generates a compact and aesthetic structure graph for a large pseudoknotted RNA structure in O([Formula: see text]) time, where n is the number of stems of the RNA structure.

Balancing bioethics by sensing the aesthetic.
Macneill, Paul
2017-10-01
This article is critical of "bioethics" as it is widely understood and taught, noting in particular an emphasis given to philosophical justification, reason and rationality. It is proposed that "balancing" bioethics be achieved by giving greater weight to practice and the aesthetic: Defined in terms of sensory perception, emotion and feeling. Each of those three elements is elaborated as a non-cognitive capacity and, when taken together, comprise aesthetic sensitivity and responsiveness. This is to recognise the aesthetic as a productive element in bioethics as practice. Contributions from the philosophy of art and aesthetics are drawn into the discussion to bring depth to an understanding of "the aesthetic". This approach is buttressed by philosophers - including Foucault and 18th century German philosophers (in particular Kant) - who recognized a link between ethics and aesthetics. The article aims to give substance to a claim that bioethics necessarily comprises a cognitive component, relating to reason, and a non-cognitive component that draws on aesthetic sensibility and relates to practice. A number of advantages of bioethics, understood to explicitly acknowledge the aesthetic, are proffered. Having defined bioethics in conventional terms, there is discussion of the extent to which other approaches to bioethics (including casuistry, virtue ethics, and narrative ethics) recognize aesthetic sensitivity in their practice. It is apparent that they do so to varying extents although not always explicitly. By examining this aspect of applied ethics, the paper aims to draw attention to aesthetic sensitivity and responsiveness as integral to ethical and effective health care. © 2017 John Wiley & Sons Ltd.

Using different methods for laying out a graph can lead to very different visual appearances, with which the viewer perceives different information. Selecting a "good" layout method is thus important for visualizing a graph. The selection can be highly subjective and dependent on the given task. A common approach to selecting a good layout is to use aesthetic criteria and visual inspection. However, fully calculating various layouts and their associated aesthetic metrics is computationally expensive. In this paper, we present a machine learning approach to large graph visualization based on computing the topological similarity of graphs using graph kernels. For a given graph, our approach can show what the graph would look like in different layouts and estimate their corresponding aesthetic metrics. An important contribution of our work is the development of a new framework to design graph kernels. Our experimental study shows that our estimation calculation is considerably faster than computing the actual layouts and their aesthetic metrics. Also, our graph kernels outperform the state-of-the-art ones in both time and accuracy. In addition, we conducted a user study to demonstrate that the topological similarity computed with our graph kernel matches perceptual similarity assessed by human users.
Psychotherapy in the aesthetic attitude.
Beebe, John
2010-04-01
Drawing upon the writings of Jungian analyst Joseph Henderson on unconscious attitudes toward culture that patients and analysts may bring to therapy, the author defines the aesthetic attitude as one of the basic ways that cultural experience is instinctively accessed and processed so that it can become part of an individual's self experience. In analytic treatment, the aesthetic attitude emerges as part of what Jung called the transcendent function to create new symbolic possibilities for the growth of consciousness. It can provide creative opportunities for new adaptation where individuation has become stuck in unconscious complexes, both personal and cultural. In contrast to formulations that have compared depth psychotherapy to religious ritual, philosophic discourse, and renewal of socialization, this paper focuses upon the considerations of beauty that make psychotherapy also an art. In psychotherapeutic work, the aesthetic attitude confronts both analyst and patient with the problem of taste, affects how the treatment is shaped and 'framed', and can grant a dimension of grace to the analyst's mirroring of the struggles that attend the patient's effort to be a more smoothly functioning human being. The patient may learn to extend the same grace to the analyst's fumbling attempts to be helpful. The author suggests that the aesthetic attitude is thus a help in the resolution of both countertransference and transference en route to psychological healing.

Planar graphs theory and algorithms
Nishizeki, T
1988-01-01
Collected in this volume are most of the important theorems and algorithms currently known for planar graphs, together with constructive proofs for the theorems. Many of the algorithms are written in Pidgin PASCAL, and are the best-known ones; the complexities are linear or 0(nlogn). The first two chapters provide the foundations of graph theoretic notions and algorithmic techniques. The remaining chapters discuss the topics of planarity testing, embedding, drawing, vertex- or edge-coloring, maximum independence set, subgraph listing, planar separator theorem, Hamiltonian cycles, and single- or multicommodity flows. Suitable for a course on algorithms, graph theory, or planar graphs, the volume will also be useful for computer scientists and graph theorists at the research level. An extensive reference section is included.

Full Text Available This article examines the modern process of aestheticization of culture and religion as consequent unfolding of the expansion of market rationality to the subjective life and the libidinal sphere of subjects. Its main objective is to inquire about the future of religion under the impact of sensation seeking culture and the inflation of aesthetics. Firstly, with the help of Türcke, Welsch, Foucault and Schultze´s investigate the aestheticization process of of social life, its causes and characteristics; Secondly, following Dufour, Türcke Leiss, Kline, Jhally e Welsch, it asks how the dynamics of aesthetical impacts the daily life and the bio-psychic economy of people; thirdly, it applies the results obtained to the analysis of what is happening with religion under the regime of aesthetics and sensational culture. Finally, it asks about the possible emancipatory potential of aestheticized own religious experience and tries to draw some further consequences for religion in the aesthetic field.
Summary: beyond fault trees to fault graphs
International Nuclear Information System (INIS)
Alesso, H.P.; Prassinos, P.; Smith, C.F.
1984-09-01
Fault Graphs are the natural evolutionary step over a traditional fault-tree model. A Fault Graph is a failure-oriented directed graph with logic connectives that allows cycles. We intentionally construct the Fault Graph to trace the piping and instrumentation drawing (P and ID) of the system, but with logical AND and OR conditions added. Then we evaluate the Fault Graph with computer codes based on graph-theoretic methods. Fault Graph computer codes are based on graph concepts, such as path set (a set of nodes traveled on a path from one node to another) and reachability (the complete set of all possible paths between any two nodes). These codes are used to find the cut-sets (any minimal set of component failures that will fail the system) and to evaluate the system reliability

Optimal Monotone Drawings of Trees
He, Dayu; He, Xin

A monotone drawing of a graph G is a straight-line drawing of G such that, for every pair of vertices u,w in G, there exists abpath P_{uw} in G that is monotone in some direction l_{uw}. (Namely, the order of the orthogonal projections of the vertices of P_{uw} on l_{uw} is the same as the order they appear in P_{uw}.) The problem of finding monotone drawings for trees has been studied in several recent papers. The main focus is to reduce the size of the drawing. Currently, the smallest drawi...

Information Technology and Aesthetics: Passive and Active Dimensions
Directory of Open Access Journals (Sweden)
John D Haynes
2007-09-01
Full Text Available This paper is concerned with examining and recognizing aesthetics in an Information System (an organization incorporating both humans and information technology. Aesthetics emerge from the wholeness of things, not from specific parts or components. As such, aesthetics may naturally be considered in “systems”, and we propose that an effective manner of thinking of aesthetics is to think in terms of “themes”. Humans have an extraordinary capacity to capture events thematically. In other words, human beings have a natural sense of aesthetics. To examine aesthetics in an information systems context, we argue that one must consider not only aesthetics that may be perceived by the senses (a passive dimension, but also aesthetics that may be conceived in the mind (an active dimension. This paper draws the conclusion that the benefits of aesthetics in relation to the study of Information Systems, has characteristics similar to the nature and importance of ethics in IS. Also, the study of aesthetics in IS has greater implications than simply recognizing and appreciating beauty and art. The very human capacity for recognizing and appreciating beauty and art is also the same capacity for effective creativity and happiness: the active aesthetic dimension. It follows that if an information system encouraged and provided the enabling circumstances for the human capacity of thematic recognition (as found in the human appreciation of art and beauty it thereby also provides the ground and the necessary thematically recognizable stimulus for effective creative and visionary organizational management.
Dynamics of aesthetic appreciation
Carbon, Claus-Christian
2012-03-01
Aesthetic appreciation is a complex cognitive processing with inherent aspects of cold as well as hot cognition. Research from the last decades of empirical has shown that evaluations of aesthetic appreciation are highly reliable. Most frequently, facial attractiveness was used as the corner case for investigating aesthetic appreciation. Evaluating facial attractiveness shows indeed high internal consistencies and impressively high inter-rater reliabilities, even across cultures. Although this indicates general and stable mechanisms underlying aesthetic appreciation, it is also obvious that our taste for specific objects changes dynamically. Aesthetic appreciation on artificial object categories, such as fashion, design or art is inherently very dynamic. Gaining insights into the cognitive mechanisms that trigger and enable corresponding changes of aesthetic appreciation is of particular interest for research as this will provide possibilities to modeling aesthetic appreciation for longer durations and from a dynamic perspective. The present paper refers to a recent two-step model ("the dynamical two-step-model of aesthetic appreciation"), dynamically adapting itself, which accounts for typical dynamics of aesthetic appreciation found in different research areas such as art history, philosophy and psychology. The first step assumes singular creative sources creating and establishing innovative material towards which, in a second step, people adapt by integrating it into their visual habits. This inherently leads to dynamic changes of the beholders' aesthetic appreciation.
Graph Treewidth and Geometric Thickness Parameters

Consider a drawing of a graph $G$ in the plane such that crossing edges are coloured differently. The minimum number of colours, taken over all drawings of $G$, is the classical graph parameter "thickness". By restricting the edges to be straight, we obtain the "geometric thickness". By further restricting the vertices to be in convex position, we obtain the "book thickness". This paper studies the relationship between these parameters and treewidth. Our first main result states that for grap...

Aesthetic Response and Cosmic Aesthetic Distance
Madacsi, D.
2013-04-01
For Homo sapiens, the experience of a primal aesthetic response to nature was perhaps a necessary precursor to the arousal of an artistic impulse. Among the likely visual candidates for primal initiators of aesthetic response, arguments can be made in favor of the flower, the human face and form, and the sky and light itself as primordial aesthetic stimulants. Although visual perception of the sensory world of flowers and human faces and forms is mediated by light, it was most certainly in the sky that humans first could respond to the beauty of light per se. It is clear that as a species we do not yet identify and comprehend as nature, or part of nature, the entire universe beyond our terrestrial environs, the universe from which we remain inexorably separated by space and time. However, we now enjoy a technologically-enabled opportunity to probe the ultimate limits of visual aesthetic distance and the origins of human aesthetic response as we remotely explore deep space via the Hubble Space Telescope and its successors.

Drawing Contour Trees in the Plane.
Heine, C; Schneider, D; Carr, Hamish; Scheuermann, G
2011-11-01
The contour tree compactly describes scalar field topology. From the viewpoint of graph drawing, it is a tree with attributes at vertices and optionally on edges. Standard tree drawing algorithms emphasize structural properties of the tree and neglect the attributes. Applying known techniques to convey this information proves hard and sometimes even impossible. We present several adaptions of popular graph drawing approaches to the problem of contour tree drawing and evaluate them. We identify five esthetic criteria for drawing contour trees and present a novel algorithm for drawing contour trees in the plane that satisfies four of these criteria. Our implementation is fast and effective for contour tree sizes usually used in interactive systems (around 100 branches) and also produces readable pictures for larger trees, as is shown for an 800 branch example.

Full Text Available Trademarks are not just property, they are aesthetic creations that pervade everyday experience. One estimate is that the average person encounters more than 1,000 trademarks per day, many of which influence purchases and product use. As pervasive aesthetic creations having literary, pictorial, graphic, sculptural, and musical content, trademarks deserve aesthetic analysis. The article discusses the origins, strength, appeal, and effectiveness of trademarks within the context of aesthetic considerations such as meaning, intention, authorship, and mode of creation. Also reviewed are morphemic and phonemic analysis of trademarks, semantic positioning, the dichotomy between creation and discovery of trademarks, and the differences between trademarks and titles. The discussion is confined to "word marks" consisting of alphanumeric characters, since discussing other kinds of marks (such as designs, configurations, sounds, colors, and scents would raise issues well beyond the scope of a single article.

Unified Photo Enhancement by Discovering Aesthetic Communities From Flickr.
Hong, Richang; Zhang, Luming; Tao, Dacheng
2016-03-01
Photo enhancement refers to the process of increasing the aesthetic appeal of a photo, such as changing the photo aspect ratio and spatial recomposition. It is a widely used technique in the printing industry, graphic design, and cinematography. In this paper, we propose a unified and socially aware photo enhancement framework which can leverage the experience of photographers with various aesthetic topics (e.g., portrait and landscape). We focus on photos from the image hosting site Flickr, which has 87 million users and to which more than 3.5 million photos are uploaded daily. First, a tagwise regularized topic model is proposed to describe the aesthetic topic of each Flickr user, and coherent and interpretable topics are discovered by leveraging both the visual features and tags of photos. Next, a graph is constructed to describe the similarities in aesthetic topics between the users. Noticeably, densely connected users have similar aesthetic topics, which are categorized into different communities by a dense subgraph mining algorithm. Finally, a probabilistic model is exploited to enhance the aesthetic attractiveness of a test photo by leveraging the photographic experiences of Flickr users from the corresponding communities of that photo. Paired-comparison-based user studies show that our method performs competitively on photo retargeting and recomposition. Moreover, our approach accurately detects aesthetic communities in a photo set crawled from nearly 100000 Flickr users.

Eigenfunction statistics on quantum graphs
International Nuclear Information System (INIS)
Gnutzmann, S.; Keating, J.P.; Piotet, F.
2010-01-01
We investigate the spatial statistics of the energy eigenfunctions on large quantum graphs. It has previously been conjectured that these should be described by a Gaussian Random Wave Model, by analogy with quantum chaotic systems, for which such a model was proposed by Berry in 1977. The autocorrelation functions we calculate for an individual quantum graph exhibit a universal component, which completely determines a Gaussian Random Wave Model, and a system-dependent deviation. This deviation depends on the graph only through its underlying classical dynamics. Classical criteria for quantum universality to be met asymptotically in the large graph limit (i.e. for the non-universal deviation to vanish) are then extracted. We use an exact field theoretic expression in terms of a variant of a supersymmetric σ model. A saddle-point analysis of this expression leads to the estimates. In particular, intensity correlations are used to discuss the possible equidistribution of the energy eigenfunctions in the large graph limit. When equidistribution is asymptotically realized, our theory predicts a rate of convergence that is a significant refinement of previous estimates. The universal and system-dependent components of intensity correlation functions are recovered by means of an exact trace formula which we analyse in the diagonal approximation, drawing in this way a parallel between the field theory and semiclassics. Our results provide the first instance where an asymptotic Gaussian Random Wave Model has been established microscopically for eigenfunctions in a system with no disorder.

Beginning with the origin of the four color problem in 1852, the field of graph colorings has developed into one of the most popular areas of graph theory. Introducing graph theory with a coloring theme, Chromatic Graph Theory explores connections between major topics in graph theory and graph colorings as well as emerging topics. This self-contained book first presents various fundamentals of graph theory that lie outside of graph colorings, including basic terminology and results, trees and connectivity, Eulerian and Hamiltonian graphs, matchings and factorizations, and graph embeddings. The remainder of the text deals exclusively with graph colorings. It covers vertex colorings and bounds for the chromatic number, vertex colorings of graphs embedded on surfaces, and a variety of restricted vertex colorings. The authors also describe edge colorings, monochromatic and rainbow edge colorings, complete vertex colorings, several distinguishing vertex and edge colorings, and many distance-related vertex coloring...

The aesthetic illusion--the experience of the content of a work of art as reality--occurs through the mobilization and intensification of typical infantile fantasies in the beholder. This necessarily evokes intrapsychic conflict in the mature adult. Two illusion-producing strategies ameliorate this conflict and effect the aesthetic illusion. The first illusion is that the artist's proffered fantasy is the beholder's own personal and private fantasy. This isolates the beholder from the shame- and guilt-evoking social surround. The second illusion is that the protagonist depicted in the work is an actual person. This defends the beholder from the painful emotions attendant upon his instinctually gratifying identification with the protagonist. The first illusion is necessary for the establishment of the second, but it is the second that establishes the aesthetic illusion. The aesthetic illusion exists in a highly unstable dynamic equilibrium with the beholder's usual reality orientation. If either orientation is too powerful, the dynamic equilibrium is disrupted and the aesthetic experience as such is abolished.

No music was presented during the task. In addition, information about participants' musical background was collected. A variety of analysis techniques was used to determine the key results of our study. The adjective "beautiful" proved to be the core item of the concept under question. Interestingly......, the adjective "touching" was often listed together with "beautiful". In addition, we found music-specific vocabulary as well as adjectives related to emotions and mood states indicating that affective processes are an essential part of aesthetic responses to music. Differences between music experts and laymen...
Joint Graph Layouts for Visualizing Collections of Segmented Meshes
Ren, Jing; Schneider, Jens; Ovsjanikov, Maks; Wonka, Peter
2017-01-01
We present a novel and efficient approach for computing joint graph layouts and then use it to visualize collections of segmented meshes. Our joint graph layout algorithm takes as input the adjacency matrices for a set of graphs along with partial, possibly soft, correspondences between nodes of different graphs. We then use a two stage procedure, where in the first step, we extend spectral graph drawing to include a consistency term so that a collection of graphs can be handled jointly. Our second step extends metric multi-dimensional scaling with stress majorization to the joint layout setting, while using the output of the spectral approach as initialization. Further, we discuss a user interface for exploring a collection of graphs. Finally, we show multiple example visualizations of graphs stemming from collections of segmented meshes and we present qualitative and quantitative comparisons with previous work.

Measuring aesthetic emotions: A review of the literature and a new assessment tool.
Directory of Open Access Journals (Sweden)
Ines Schindler
Full Text Available Aesthetic perception and judgement are not merely cognitive processes, but also involve feelings. Therefore, the empirical study of these experiences requires conceptualization and measurement of aesthetic emotions. Despite the long-standing interest in such emotions, we still lack an assessment tool to capture the broad range of emotions that occur in response to the perceived aesthetic appeal of stimuli. Elicitors of aesthetic emotions are not limited to the arts in the strict sense, but extend to design, built environments, and nature. In this article, we describe the development of a questionnaire that is applicable across many of these domains: the Aesthetic Emotions Scale (Aesthemos. Drawing on theoretical accounts of aesthetic emotions and an extensive review of extant measures of aesthetic emotions within specific domains such as music, literature, film, painting, advertisements, design, and architecture, we propose a framework for studying aesthetic emotions. The Aesthemos, which is based on this framework, contains 21 subscales with two items each, that are designed to assess the emotional signature of responses to stimuli's perceived aesthetic appeal in a highly differentiated manner. These scales cover prototypical aesthetic emotions (e.g., the feeling of beauty, being moved, fascination, and awe, epistemic emotions (e.g., interest and insight, and emotions indicative of amusement (humor and joy. In addition, the Aesthemos subscales capture both the activating (energy and vitality and the calming (relaxation effects of aesthetic experiences, as well as negative emotions that may contribute to aesthetic displeasure (e.g., the feeling of ugliness, boredom, and confusion.

That is Cool: the Nature Of Aesthetics in Fluid Physics
Hertzberg, Jean
2013-11-01
Aesthetics has historically been defined as the study of beauty and thus as a metric of art. More recently, psychologists are using the term to describe a spectrum of responses from ``I hate it'' to ``I love it.'' In the context of fluid physics, what is beautiful? What elicits a ``Wow! Awesome! Cool!'' response versus a snore? Can we use aesthetics to deepen or change students' or the public's perceptions of physics and/or the world around them? For example, students seem to appreciate the aesthetics of destruction: environmental fluid dynamics such as storms, tornadoes, floods and wildfires are often responsible for massive destruction, yet humans draw pleasure from watching such physics and the attendant destruction from a safe distance. Can this voyeurism be turned to our advantage in communicating science? Observations of student and Facebook Flow Visualization group choices for fluid physics that draw a positive aesthetic response are sorted into empirical categories; the aesthetics of beauty, power, destruction, and oddness. Each aesthetic will be illustrated with examples drawn from flow visualizations from both the Flow Visualization course (MCEN 4151) taught at the University of Colorado, Boulder, and sources on the web.

Aesthetic experience of dance performances

2012-01-01
Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

[History of aesthetic rhinoplasty].
Nguyen, P S; Mazzola, R F
2014-12-01
One of the first surgical procedures described in the history of medicine is reconstructive surgery of the nose. Over the centuries, surgeons have developed techniques aimed at reconstructing noses amputated or traumatized by disease. The concept of aesthetic rhinoplasty was only introduced at the end of the 19th century. Since then, techniques have evolved toward constant ameliorations. Nowadays, this surgery is one of the most performed aesthetic procedures. Current technical sophistication is the result of over a century of history marked by many surgeons. All of these techniques derive from a detailed understanding of the anatomical nose from the surgical and artistic point of view. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

The concept of aesthetic self-esteem was explored for utilization in the medical spa environment. The aims and purposes of the analysis were outlined. The literature review identified various uses of the self-esteem concept as well as published definitions of the word. Defining attributes were also explored and examined, including positive and negative connotations of self-esteem. Two tools were utilized to help aesthetic nurse specialists assess patients for self-esteem and assess for a possible mental illness that may present as low self-esteem. A culturally sensitive theoretical definition of self-esteem was constructed to fit the needs and environment of medical spas. A model case of this definition, as well as a borderline and contrary case, was presented. Antecedents and consequences, as well as empirical referents of the concept, were explored.
Teaching 5th grade science for aesthetic understanding
Girod, Mark A.
Many scientists speak with great zeal about the role of aesthetics and beauty in their science and inquiry. Few systematic efforts have been made to teach science in ways that appeal directly to aesthetics and this research is designed to do just that. Drawing from the aesthetic theory of Dewey, I describe an analytic lens called learning for aesthetic understanding that finds power in the degree to which our perceptions of the world are transformed, our interests and enthusiasm piqued, and our actions changed as we seek further experiences in the world. This learning theory is contrasted against two other current and popular theories of science learning, that of learning for conceptual understanding via conceptual change theory and learning for a language-oriented or discourse-based understanding. After a lengthy articulation of the pedagogical strategies used to teach for aesthetic understanding the research is described in which comparisons are drawn between students in two 5th grade classrooms---one taught for the goal of conceptual understanding and the other taught for the goal of aesthetic understanding. Results of this comparison show that more students in the treatment classroom had aesthetic experiences with science ideas and came to an aesthetic understanding when studying weather, erosion, and structure of matter than students in the control group. Also statistically significant effects are shown on measures of interest, affect, and efficacy for students in the treatment class. On measures of conceptual understanding it appears that treatment class students learned more and forgot less over time than control class students. The effect of the treatment does not generally depend on gender, ethnicity, or prior achievement except in students' identity beliefs about themselves as science learners. In this case, a significant interaction for treatment class females on science identity beliefs did occur. A discussion of these results as well as elaboration and

This new edition illustrates the power of linear algebra in the study of graphs. The emphasis on matrix techniques is greater than in other texts on algebraic graph theory. Important matrices associated with graphs (for example, incidence, adjacency and Laplacian matrices) are treated in detail. Presenting a useful overview of selected topics in algebraic graph theory, early chapters of the text focus on regular graphs, algebraic connectivity, the distance matrix of a tree, and its generalized version for arbitrary graphs, known as the resistance matrix. Coverage of later topics include Laplacian eigenvalues of threshold graphs, the positive definite completion problem and matrix games based on a graph. Such an extensive coverage of the subject area provides a welcome prompt for further exploration. The inclusion of exercises enables practical learning throughout the book. In the new edition, a new chapter is added on the line graph of a tree, while some results in Chapter 6 on Perron-Frobenius theory are reo...

Synchronized movement is a ubiquitous feature of dance and music performance. Much research into the evolutionary origins of these cultural practices has focused on why humans perform rather than watch or listen to dance and music. In this study, we show that movement synchrony among a group of performers predicts the aesthetic appreciation of live dance performances. We developed a choreography that continuously manipulated group synchronization using a defined movement vocabulary based on arm swinging, walking and running. The choreography was performed live to four audiences, as we continuously tracked the performers' movements, and the spectators' affective responses. We computed dynamic synchrony among performers using cross recurrence analysis of data from wrist accelerometers, and implicit measures of arousal from spectators' heart rates. Additionally, a subset of spectators provided continuous ratings of enjoyment and perceived synchrony using tablet computers. Granger causality analyses demonstrate predictive relationships between synchrony, enjoyment ratings and spectator arousal, if audiences form a collectively consistent positive or negative aesthetic evaluation. Controlling for the influence of overall movement acceleration and visual change, we show that dance communicates group coordination via coupled movement dynamics among a group of performers. Our findings are in line with an evolutionary function of dance-and perhaps all performing arts-in transmitting social signals between groups of people. Human movement is the common denominator of dance, music and theatre. Acknowledging the time-sensitive and immediate nature of the performer-spectator relationship, our study makes a significant step towards an aesthetics of joint actions in the performing arts.

Graph Convolutional Neural Networks (Graph CNNs) are generalizations of classical CNNs to handle graph data such as molecular data, point could and social networks. Current filters in graph CNNs are built for fixed and shared graph structure. However, for most real data, the graph structures varies in both size and connectivity. The paper proposes a generalized and flexible graph CNN taking data of arbitrary graph structure as input. In that way a task-driven adaptive graph is learned for eac...

Full Text Available We study a family of graphs related to the $n$-cube. The middle cube graph of parameter k is the subgraph of $Q_{2k-1}$ induced by the set of vertices whose binary representation has either $k-1$ or $k$ number of ones. The middle cube graphs can be obtained from the well-known odd graphs by doubling their vertex set. Here we study some of the properties of the middle cube graphs in the light of the theory of distance-regular graphs. In particular, we completely determine their spectra (eigenvalues and their multiplicities, and associated eigenvectors.
Graph-theoretical concepts and physicochemical data

Full Text Available Graph theoretical concepts have been used to model the molecular polarizabilities of fifty-four organic derivatives, and the induced dipole moment of a set of fifty-seven organic compounds divided into three subsets. The starting point of these modeling strategies is the hydrogen-suppressed chemical graph and pseudograph of a molecule, which works very well for second row atoms. From these types of graphs a set of graph-theoretical basis indices, the molecular connectivity indices, can be derived and used to model properties and activities of molecules. With the aid of the molecular connectivity basis indices it is then possible to build higher-order descriptors. The problem of 'graph' encoding the contribution of the inner-core electrons of heteroatoms can here be solved with the aid of odd complete graphs, Kp-(p-odd. The use of these graph tools allow to draw an optimal modeling of the molecular polarizabilities and a satisfactory modeling of the induced dipole moment of a wide set of organic derivatives.
Can medicine be aesthetic? Disentangling beauty and health in elective surgeries.
Edmonds, Alexander
2013-06-01
This article analyzes tensions between aesthetics and health in medicine. The blurring of distinctions between reconstructive and cosmetic procedures, and the linking of plastic surgery with other medical treatments, have added to the legitimacy of an emerging "aesthetic medicine." As cosmetic surgeries become linked to other medical procedures with perceived greater medical necessity, health and aesthetics become entangled. One consequence is that medical needs are magnified while perceptions of the risks of surgery are minimized. Drawing on ethnographic work on plastic surgery, as well as other studies of obstetrics and cosmetic surgery, I illustrate this entanglement of health and aesthetics within the field of women's reproductive health care in Brazil. I argue that while it would be difficult to wholly disentangle aesthetics and health, analysis of how risk-benefit calculations are made in clinical practice offers a useful critical strategy for illuminating ethical problems posed by aesthetic medicine. © 2013 by the American Anthropological Association.
Aesthetic procedures in office practice.
Small, Rebecca
2009-12-01
Since the approval of botulinum toxin, dermal fillers, and lasers for cosmetic use, minimally invasive aesthetic procedures have rapidly become the treatments of choice for age-related facial changes. In the past 10 years, aesthetic procedures have increased nearly five-fold. Of the 10.2 million aesthetic treatments performed in 2008, 83 percent were minimally invasive procedures. Botulinum toxin and dermal filler injections, laser hair reduction, chemical peels, laser skin resurfacing, microdermabrasion, and intense pulsed light photorejuvenation were the most commonly performed procedures in 2008. These procedures are effective and associated with minimal discomfort, and they have a low incidence of adverse effects and short recovery times. High patient and physician satisfaction have contributed to their growing popularity and availability in the primary care setting. As patient demand for aesthetic treatments increases, family physicians should be familiar with common minimally invasive aesthetic procedures when advising patients or incorporating aesthetic care into office practice.

Full Text Available The topic of identifying the similarity of graphs was considered as highly recommended research field in the Web semantic, artificial intelligence, the shape recognition and information research. One of the fundamental problems of graph databases is finding similar graphs to a graph query. Existing approaches dealing with this problem are usually based on the nodes and arcs of the two graphs, regardless of parental semantic links. For instance, a common connection is not identified as being part of the similarity of two graphs in cases like two graphs without common concepts, the measure of similarity based on the union of two graphs, or the one based on the notion of maximum common sub-graph (SCM, or the distance of edition of graphs. This leads to an inadequate situation in the context of information research. To overcome this problem, we suggest a new measure of similarity between graphs, based on the similarity measure of Wu and Palmer. We have shown that this new measure satisfies the properties of a measure of similarities and we applied this new measure on examples. The results show that our measure provides a run time with a gain of time compared to existing approaches. In addition, we compared the relevance of the similarity values obtained, it appears that this new graphs measure is advantageous and offers a contribution to solving the problem mentioned above.

Graph complexes show up naturally in many different areas of mathematics, including commutative algebra, geometry, and knot theory. Identifying each graph with its edge set, one may view a graph complex as a simplicial complex and hence interpret it as a geometric object. This volume examines topological properties of graph complexes, focusing on homotopy type and homology. Many of the proofs are based on Robin Forman's discrete version of Morse theory. As a byproduct, this volume also provides a loosely defined toolbox for attacking problems in topological combinatorics via discrete Morse theory. In terms of simplicity and power, arguably the most efficient tool is Forman's divide and conquer approach via decision trees; it is successfully applied to a large number of graph and digraph complexes.
Introduction to quantum graphs
Berkolaiko, Gregory
2012-01-01
A "quantum graph" is a graph considered as a one-dimensional complex and equipped with a differential operator ("Hamiltonian"). Quantum graphs arise naturally as simplified models in mathematics, physics, chemistry, and engineering when one considers propagation of waves of various nature through a quasi-one-dimensional (e.g., "meso-" or "nano-scale") system that looks like a thin neighborhood of a graph. Works that currently would be classified as discussing quantum graphs have been appearing since at least the 1930s, and since then, quantum graphs techniques have been applied successfully in various areas of mathematical physics, mathematics in general and its applications. One can mention, for instance, dynamical systems theory, control theory, quantum chaos, Anderson localization, microelectronics, photonic crystals, physical chemistry, nano-sciences, superconductivity theory, etc. Quantum graphs present many non-trivial mathematical challenges, which makes them dear to a mathematician's heart. Work on qu...

Teaching and Learning Science for Transformative, Aesthetic Experience
Girod, Mark; Twyman, Todd; Wojcikiewicz, Steve
2010-11-01
Drawing from the Deweyan theory of experience (1934, 1938), the goal of teaching and learning for transformative, aesthetic experience is contrasted against teaching and learning from a cognitive, rational framework. A quasi-experimental design was used to investigate teaching and learning of fifth grade science from each perspective across an entire school year including three major units of instruction. Detailed comparisons of teaching are given and pre and post measures of interest in learning science, science identity affiliation, and efficacy beliefs are investigated. Tests of conceptual understanding before, after, and one month after instruction reveal teaching for transformative, aesthetic experience fosters more, and more enduring, learning of science concepts. Investigations of transfer also suggest students learning for transformative, aesthetic experiences learn to see the world differently and find more interest and excitement in the world outside of school.

Miserere. Aesthetics of Terror

Antonio Incampo
2011-10-01
Full Text Available I say: “Oh, what a beautiful surrealist picture!” With quite precise awareness: this páthos, these emotions of mine do not stem from our common sense. An aesthetic judgment is founded on an immediate subjective intuition: an emotion or a free feeling of a single subject towards an object. A universal sense, possibly. Some judgments of ours in ethics and in law are no different from our perceptions in front of art. It would be the same for a hypothetical sentence of the judge that concluded with these words: “I acquit Arsenio Lupin because of his magnificent handlebar moustache like that of Guy de Maupassant”. Everyone would think intuitively that it is an unfair sentence. Is there aesthetics of terror? The case that the article intends to examine is that of the famous kidnapping and murder of the Italian statesman Aldo Moro by the “Brigate Rosse” [Red Brigades] (1978. The method used here consists in studying the image of the kidnapping as iconic documentation of reality, and, above all, as an ethical-legal judgment about the terrorist crime. Moro was photographed during his kidnapping. There are at least two pictures. Both constitute an extraordinary source for a judgment on the basis of an image. In both of them, Aldo Moro is pictured in front of a Red Brigades banner during the captivity. In what sense do these pictures document an aesthetic judgment concerning the “case Moro”? The answer can be found in a remarkable iconic coincidence of these pictures with a masterpiece by Georges Rouault (Paris 1871-1958 devoted to the theme of the “Ecce Homo”. The Gospel in the “Ecce Homo” scene (John: 19, 4-5 narrates how Pontius Pilate wanted to arouse the compassion of the people with a scourging and the exposure of Jesus to the crowd. The plate under consideration is entitled “Qui ne se grime pas?” [Who does not have a painted face?] and is a key work in Rouault’s suite of prints Miserere, dated for 1923.

The psychology of Kant's aesthetics.
Guyer, Paul
2008-12-01
Contrary to both his own intentions and the views of both older and more recent commentators. I argue that Kant's aesthetics remains within the confines of eighteenth-century aesthetics as a branch of empirical psychology, as it was then practiced. Kant established a plausible connection between aesthetic experience and judgment on the one hand and cognition in general on the other, through his explanatory concept of the free play of our cognitive powers. However, there is nothing distinctly 'a priori' or 'transcendental' in his claim that this state of mind is what causes our pleasure in beauty or other aesthetic properties. Nor did Kant establish a genuinely a priori or transcendental principle that all human beings have the same disposition to experience a free play of their cognitive powers, let alone in response to the same objects. This failure, however, in no way limits the continuing significance of Kant's aesthetic theory.

Graphing trillions of triangles.
Burkhardt, Paul
2017-07-01
The increasing size of Big Data is often heralded but how data are transformed and represented is also profoundly important to knowledge discovery, and this is exemplified in Big Graph analytics. Much attention has been placed on the scale of the input graph but the product of a graph algorithm can be many times larger than the input. This is true for many graph problems, such as listing all triangles in a graph. Enabling scalable graph exploration for Big Graphs requires new approaches to algorithms, architectures, and visual analytics. A brief tutorial is given to aid the argument for thoughtful representation of data in the context of graph analysis. Then a new algebraic method to reduce the arithmetic operations in counting and listing triangles in graphs is introduced. Additionally, a scalable triangle listing algorithm in the MapReduce model will be presented followed by a description of the experiments with that algorithm that led to the current largest and fastest triangle listing benchmarks to date. Finally, a method for identifying triangles in new visual graph exploration technologies is proposed.

The spatial frequencies influence the aesthetic judgment of buildings transculturally.
Vannucci, Manila; Gori, Simone; Kojima, Haruyuki
2014-01-01
Recent evidence has shown that buildings designed to be high-ranking, according to the Western architectural decorum, have more impact on the minds of their beholders than low-ranking buildings. Here we investigated whether and how the aesthetic judgment for high- and low-ranking buildings was affected by differences in cultural expertise and by power spectrum differences. A group of Italian and Japanese participants performed aesthetic judgment tasks, with line drawings of high- and low-ranking buildings and with their random-phase versions (an image with the exact power spectrum of the original one but non-recognizable anymore). Irrespective of cultural expertise, high-ranking buildings and their relative random-phase versions received higher aesthetic judgments than low-ranking buildings and their random-phase versions. These findings indicate that high- and low-ranking buildings are differentiated for their aesthetic value and they show that low-level visual processes influence the aesthetic judgment based on differences in the stimuli power spectrum, irrespective of the influence of cultural expertise.
Aesthetic and emotional effects of meter and rhyme in poetry.
Obermeier, Christian; Menninghaus, Winfried; von Koppenfels, Martin; Raettig, Tim; Schmidt-Kassow, Maren; Otterbein, Sascha; Kotz, Sonja A
2013-01-01
Metrical patterning and rhyme are frequently employed in poetry but also in infant-directed speech, play, rites, and festive events. Drawing on four line-stanzas from nineteenth and twentieth German poetry that feature end rhyme and regular meter, the present study tested the hypothesis that meter and rhyme have an impact on aesthetic liking, emotional involvement, and affective valence attributions. Hypotheses that postulate such effects have been advocated ever since ancient rhetoric and poetics, yet they have barely been empirically tested. More recently, in the field of cognitive poetics, these traditional assumptions have been readopted into a general cognitive framework. In the present experiment, we tested the influence of meter and rhyme as well as their interaction with lexicality in the aesthetic and emotional perception of poetry. Participants listened to stanzas that were systematically modified with regard to meter and rhyme and rated them. Both rhyme and regular meter led to enhanced aesthetic appreciation, higher intensity in processing, and more positively perceived and felt emotions, with the latter finding being mediated by lexicality. Together these findings clearly show that both features significantly contribute to the aesthetic and emotional perception of poetry and thus confirm assumptions about their impact put forward by cognitive poetics. The present results are explained within the theoretical framework of cognitive fluency, which links structural features of poetry with aesthetic and emotional appraisal.

About a decade ago, psychology of the arts started to gain momentum owing to a number of drives: technological progress improved the conditions under which art could be studied in the laboratory, neuroscience discovered the arts as an area of interest, and new theories offered a more comprehensive look at aesthetic experiences. Ten years ago, Leder, Belke, Oeberst, and Augustin (2004) proposed a descriptive information-processing model of the components that integrate an aesthetic episode. This theory offered explanations for modern art's large number of individualized styles, innovativeness, and for the diverse aesthetic experiences it can stimulate. In addition, it described how information is processed over the time course of an aesthetic episode, within and over perceptual, cognitive and emotional components. Here, we review the current state of the model, and its relation to the major topics in empirical aesthetics today, including the nature of aesthetic emotions, the role of context, and the neural and evolutionary foundations of art and aesthetics. © 2014 The British Psychological Society.
Aesthetic occiput augmentation using methylmethacrylate.
Song, Yong Tai
2015-01-01
Cranioplasty for only aesthetic reasons has not been commonly performed to date. However, recently there has been a new focus by the public on a more aesthetically pleasing head shape with frequent patient requests for purely aesthetic contouring of the occiput, an important definer of cosmetic head shape. For example, in Asia, where the normal cranial shape is mesocephalic or brachycephalic and often with a planar occiput, requests for its aesthetic correction are increasingly common. Accordingly, the author developed a minimally invasive occiput augmentation using methylmethacrylate. In this study, the indications for aesthetic occiput contouring were planar occiput, left-right asymmetric occiput, and grooved occiput. Under local anesthesia, soft methylmethacrylate is subperiosteally inserted through a small incision (about 5-cm length), manually and precisely contoured in situ through the scalp to the desired occipital shape. All is performed as an outpatient procedure, and a quick recovery is the case. Between March 2007 and October 2013, 959 patients received such aesthetic occiput augmentation. The mean follow-up period was 49 months (range, 3-84 months). Nearly all patients were satisfied with the outcome, and complications were very rare. Only 5 patients (0.5%) needed additional corrective procedures. The author has concluded that aesthetic occiput augmentation using methylmethacrylate yields consistent, predictable, and satisfactory results. Additional long-term follow-up is required for a final conclusion, however.
Long Memory of Pathfinding Aesthetics

Full Text Available This paper investigates a new dynamic (i.e., space-time model to measure aesthetic values in pathfinding for videogames. The results we report are important firstly because the artificial intelligence literature has given relatively little attention to aesthetic considerations in pathfinding. Secondly, those investigators who have studied aesthetics in pathfinding have relied largely on anecdotal arguments rather than metrics. Finally, in those cases where metrics have been used in the past, they show only that aesthetic paths are different. They provide no quantitative means to classify aesthetic outcomes. The model we develop here overcomes these deficiencies using rescaled range (R/S analysis to estimate the Hurst exponent, . It measures long-range dependence (i.e., long memory in stochastic processes and provides a novel well-defined mathematical classification for pathfinding. Indeed, the data indicates that aesthetic and control paths have statistically significantly distinct signatures. Aesthetic paths furthermore have more long memory than controls with an effect size that is large, more than three times that of an alternative approach. These conclusions will be of interest to researchers investigating games as well as other forms of entertainment, simulation, and in general nonshortest path motion planning.

Full Text Available String diagrams are a powerful tool for reasoning about physical processes, logic circuits, tensor networks, and many other compositional structures. Dixon, Duncan and Kissinger introduced string graphs, which are a combinatoric representations of string diagrams, amenable to automated reasoning about diagrammatic theories via graph rewrite systems. In this extended abstract, we show how the power of such rewrite systems can be greatly extended by introducing pattern graphs, which provide a means of expressing infinite families of rewrite rules where certain marked subgraphs, called !-boxes ("bang boxes", on both sides of a rule can be copied any number of times or removed. After reviewing the string graph formalism, we show how string graphs can be extended to pattern graphs and how pattern graphs and pattern rewrite rules can be instantiated to concrete string graphs and rewrite rules. We then provide examples demonstrating the expressive power of pattern graphs and how they can be applied to study interacting algebraic structures that are central to categorical quantum mechanics.

Sonic morphology: Aesthetic dimensional auditory spatial awareness
Whitehouse, Martha M.
The sound and ceramic sculpture installation, " Skirting the Edge: Experiences in Sound & Form," is an integration of art and science demonstrating the concept of sonic morphology. "Sonic morphology" is herein defined as aesthetic three-dimensional auditory spatial awareness. The exhibition explicates my empirical phenomenal observations that sound has a three-dimensional form. Composed of ceramic sculptures that allude to different social and physical situations, coupled with sound compositions that enhance and create a three-dimensional auditory and visual aesthetic experience (see accompanying DVD), the exhibition supports the research question, "What is the relationship between sound and form?" Precisely how people aurally experience three-dimensional space involves an integration of spatial properties, auditory perception, individual history, and cultural mores. People also utilize environmental sound events as a guide in social situations and in remembering their personal history, as well as a guide in moving through space. Aesthetically, sound affects the fascination, meaning, and attention one has within a particular space. Sonic morphology brings art forms such as a movie, video, sound composition, and musical performance into the cognitive scope by generating meaning from the link between the visual and auditory senses. This research examined sonic morphology as an extension of musique concrete, sound as object, originating in Pierre Schaeffer's work in the 1940s. Pointing, as John Cage did, to the corporeal three-dimensional experience of "all sound," I composed works that took their total form only through the perceiver-participant's participation in the exhibition. While contemporary artist Alvin Lucier creates artworks that draw attention to making sound visible, "Skirting the Edge" engages the perceiver-participant visually and aurally, leading to recognition of sonic morphology.
Measuring aesthetic emotions: A review of the literature and a new assessment tool
Hosoya, Georg; Menninghaus, Winfried; Beermann, Ursula; Wagner, Valentin; Eid, Michael; Scherer, Klaus R.

Aesthetic perception and judgement are not merely cognitive processes, but also involve feelings. Therefore, the empirical study of these experiences requires conceptualization and measurement of aesthetic emotions. Despite the long-standing interest in such emotions, we still lack an assessment tool to capture the broad range of emotions that occur in response to the perceived aesthetic appeal of stimuli. Elicitors of aesthetic emotions are not limited to the arts in the strict sense, but extend to design, built environments, and nature. In this article, we describe the development of a questionnaire that is applicable across many of these domains: the Aesthetic Emotions Scale (Aesthemos). Drawing on theoretical accounts of aesthetic emotions and an extensive review of extant measures of aesthetic emotions within specific domains such as music, literature, film, painting, advertisements, design, and architecture, we propose a framework for studying aesthetic emotions. The Aesthemos, which is based on this framework, contains 21 subscales with two items each, that are designed to assess the emotional signature of responses to stimuli’s perceived aesthetic appeal in a highly differentiated manner. These scales cover prototypical aesthetic emotions (e.g., the feeling of beauty, being moved, fascination, and awe), epistemic emotions (e.g., interest and insight), and emotions indicative of amusement (humor and joy). In addition, the Aesthemos subscales capture both the activating (energy and vitality) and the calming (relaxation) effects of aesthetic experiences, as well as negative emotions that may contribute to aesthetic displeasure (e.g., the feeling of ugliness, boredom, and confusion).

Aesthetic Diagnosis in Gestalt Therapy.
Roubal, Jan; Francesetti, Gianni; Gecele, Michela
2017-10-17
The diagnostic process in psychotherapy using the aesthetic evaluation is described in this article. Unlike the classical diagnostic process, which presents a result of comparing clinicians´ observations with a diagnostic system (DSM, ICD, etc.), the aesthetic evaluation is a pre-reflexive, embodied, and preverbal process. A Gestalt Therapy theoretical frame is used to introduce a concept of the aesthetic diagnostic process. During this process, the clinicians use their own here-and-now presence, which takes part in the co-creation of the shared relational field during the therapeutic session. A specific procedure of the aesthetic evaluation is introduced. The clinical work with depressed clients is presented to illustrate this perspective.
Aura, Self, and Aesthetic Experience

Marshall Battani
2011-01-01
Full Text Available Aesthetic experiences are generated in encounters with cultural objects and such experiences are marked by the free play of cognitive and numinous experience unstructured by concepts. Kant’s famous three types of pleasure, made infamous in social theory by Pierre Bourdieu, are examined in relation to the critical theoretical concept of aura, the social psychology of “flow,” and cognitive explanations of perception to explain experience in aesthetic fields. Theories of aesthetic experience developed at the crossroad of critical social thought and cognitive science hold promise for a social analysis able to avoid the usual sociological pitfalls of either ignoring aesthetics or reducing it to structurally determined differences of taste.

Full Text Available While ecocriticism has become a respected field in literary theory and in the broader landscape of aesthetic philosophy, it could benefit from an enhanced ethical-political framework which social ecology – an underrated critical theory developed by Murray Bookchin – could provide. This essay attempts to tease out the potentials for such a framework, integrating the insights of social ecology, ecocriticism, Critical Realism, and John Dewey's aesthetic concepts into a layered idea-set used for the study of all kinds of aesthetic objects, from popular art to the gallery arts. Its key principles are the emergence of aesthetic objects (including formal artworks out of congealed human experience, the relation between organism and environment in assessing meaning, the breakdown of implicit or overt hierarchies within a work, and the idea of the artist and art-critic as a "gardener".
Aesthetic Diagnosis in Gestalt Therapy
Directory of Open Access Journals (Sweden)
Jan Roubal
2017-10-01
Full Text Available The diagnostic process in psychotherapy using the aesthetic evaluation is described in this article. Unlike the classical diagnostic process, which presents a result of comparing clinicians´ observations with a diagnostic system (DSM, ICD, etc., the aesthetic evaluation is a pre-reflexive, embodied, and preverbal process. A Gestalt Therapy theoretical frame is used to introduce a concept of the aesthetic diagnostic process. During this process, the clinicians use their own here-and-now presence, which takes part in the co-creation of the shared relational field during the therapeutic session. A specific procedure of the aesthetic evaluation is introduced. The clinical work with depressed clients is presented to illustrate this perspective.

This textbook acts as a pathway to higher mathematics by seeking and illuminating the connections between graph theory and diverse fields of mathematics, such as calculus on manifolds, group theory, algebraic curves, Fourier analysis, cryptography and other areas of combinatorics. An overview of graph theory definitions and polynomial invariants for graphs prepares the reader for the subsequent dive into the applications of graph theory. To pique the reader’s interest in areas of possible exploration, recent results in mathematics appear throughout the book, accompanied with examples of related graphs, how they arise, and what their valuable uses are. The consequences of graph theory covered by the authors are complicated and far-reaching, so topics are always exhibited in a user-friendly manner with copious graphs, exercises, and Sage code for the computation of equations. Samples of the book’s source code can be found at github.com/springer-math/adventures-in-graph-theory. The text is geared towards ad...

Generating Realistic Labelled, Weighted Random Graphs
Directory of Open Access Journals (Sweden)
Michael Charles Davis
2015-12-01
Full Text Available Generative algorithms for random graphs have yielded insights into the structure and evolution of real-world networks. Most networks exhibit a well-known set of properties, such as heavy-tailed degree distributions, clustering and community formation. Usually, random graph models consider only structural information, but many real-world networks also have labelled vertices and weighted edges. In this paper, we present a generative model for random graphs with discrete vertex labels and numeric edge weights. The weights are represented as a set of Beta Mixture Models (BMMs with an arbitrary number of mixtures, which are learned from real-world networks. We propose a Bayesian Variational Inference (VI approach, which yields an accurate estimation while keeping computation times tractable. We compare our approach to state-of-the-art random labelled graph generators and an earlier approach based on Gaussian Mixture Models (GMMs. Our results allow us to draw conclusions about the contribution of vertex labels and edge weights to graph structure.
Autoregressive Moving Average Graph Filtering

One of the cornerstones of the field of signal processing on graphs are graph filters, direct analogues of classical filters, but intended for signals defined on graphs. This work brings forth new insights on the distributed graph filtering problem. We design a family of autoregressive moving average (ARMA) recursions, which (i) are able to approximate any desired graph frequency response, and (ii) give exact solutions for tasks such as graph signal denoising and interpolation. The design phi...
Localization in random bipartite graphs: Numerical and empirical study
Slanina, František
2017-05-01
We investigate adjacency matrices of bipartite graphs with a power-law degree distribution. Motivation for this study is twofold: first, vibrational states in granular matter and jammed sphere packings; second, graphs encoding social interaction, especially electronic commerce. We establish the position of the mobility edge and show that it strongly depends on the power in the degree distribution and on the ratio of the sizes of the two parts of the bipartite graph. At the jamming threshold, where the two parts have the same size, localization vanishes. We found that the multifractal spectrum is nontrivial in the delocalized phase, but still near the mobility edge. We also study an empirical bipartite graph, namely, the Amazon reviewer-item network. We found that in this specific graph the mobility edge disappears, and we draw a conclusion from this fact regarding earlier empirical studies of the Amazon network.
Subgraph detection using graph signals
Chepuri, Sundeep Prabhakar
2017-03-06
In this paper we develop statistical detection theory for graph signals. In particular, given two graphs, namely, a background graph that represents an usual activity and an alternative graph that represents some unusual activity, we are interested in answering the following question: To which of the two graphs does the observed graph signal fit the best? To begin with, we assume both the graphs are known, and derive an optimal Neyman-Pearson detector. Next, we derive a suboptimal detector for the case when the alternative graph is not known. The developed theory is illustrated with numerical experiments.

Naturalizing aesthetics: brain areas for aesthetic appraisal across sensory modalities.
Brown, Steven; Gao, Xiaoqing; Tisdelle, Loren; Eickhoff, Simon B; Liotti, Mario
2011-09-01
We present here the most comprehensive analysis to date of neuroaesthetic processing by reporting the results of voxel-based meta-analyses of 93 neuroimaging studies of positive-valence aesthetic appraisal across four sensory modalities. The results demonstrate that the most concordant area of activation across all four modalities is the right anterior insula, an area typically associated with visceral perception, especially of negative valence (disgust, pain, etc.). We argue that aesthetic processing is, at its core, the appraisal of the valence of perceived objects. This appraisal is in no way limited to artworks but is instead applicable to all types of perceived objects. Therefore, one way to naturalize aesthetics is to argue that such a system evolved first for the appraisal of objects of survival advantage, such as food sources, and was later co-opted in humans for the experience of artworks for the satisfaction of social needs.

Organization aesthetics in nursing homes.
Hujala, Anneli; Rissanen, Sari
2011-05-01
The aim of this study was to make visible the material dimensions of nursing management. Management theories have mainly ignored the material dimensions, namely the physical spaces in which management actually takes place as well as the physical bodies of organization members. The perspective of organization aesthetics enhances our understanding of the role of materiality in nursing management. The data were collected in 2009 using observation and interviews in eight nursing homes. Qualitative content analysis with critical interpretations was used. Three main issues of organizational aesthetics related to nursing management were identified: (1) the functionality of working spaces and equipment; (2) the relevance of 'organizational' space; and (3) the emotional-aesthetic dimension of daily work. Materiality is closely related to management topics, such as decision-making, values and identity formation of organizational members. Aesthetic dimensions of care are constructed by management practices which, in their turn, influence the nature of management. Implications for nursing management Nurse managers need to be aware of the unintended and unnoticed consequences of materiality and aesthetics. Space and body issues may have considerable effects, for example, on the identity of care workers and on the attractiveness of the care branch. © 2011 The Authors.

Full Text Available A path π = (v1, v2, . . . , vk+1 in a graph G = (V,E is a downhill path if for every i, 1 ≤ i ≤ k, deg(vi ≥ deg(vi+1, where deg(vi denotes the degree of vertex vi ∈ V. The downhill domination number equals the minimum cardinality of a set S ⊆ V having the property that every vertex v ∈ V lies on a downhill path originating from some vertex in S. We investigate downhill domination numbers of graphs and give upper bounds. In particular, we show that the downhill domination number of a graph is at most half its order, and that the downhill domination number of a tree is at most one third its order. We characterize the graphs obtaining each of these bounds

Tailored graph ensembles are a developing bridge between biological networks and statistical mechanics. The aim is to use this concept to generate a suite of rigorous tools that can be used to quantify and compare the topology of cellular signalling networks, such as protein-protein interaction networks and gene regulation networks. We calculate exact and explicit formulae for the leading orders in the system size of the Shannon entropies of random graph ensembles constrained with degree distribution and degree-degree correlation. We also construct an ergodic detailed balance Markov chain with non-trivial acceptance probabilities which converges to a strictly uniform measure and is based on edge swaps that conserve all degrees. The acceptance probabilities can be generalized to define Markov chains that target any alternative desired measure on the space of directed or undirected graphs, in order to generate graphs with more sophisticated topological features.

AUMGARTEN’S AESTHETICS AS THE SCIENCE OF SENSITIVE COGNITION

Full Text Available A. G. Baumgarten grounds the aesthetics of which he was the founder on widely poetic and rhetoric in his ‘Aestetica’ (1750/58. Nevertheless, what is significant here for him is to validate the individualist right of ‘sensitive knowledge.’ The word ‘aesthetics’ (αíσυŋгηικόç here is strictly attached to its basic meaning which is ‘related to sense and perception,’ and ‘sensually understandable.’ The aesthetics of Baumgarten is the philosophy of sensual knowledge and perception, and its sensitivity cannot be perceived as the material of outer stimulation and logic; contrarily, it sincerely sees it as a special genre of the knowledge. Hence, the aesthetics is defined as the ‘science of sensitive knowledge.’ With this study, it has been targeted to draw a general outline of Baumgarten’s aesthetics understanding by discussing the basic chapters of ‘Aestetica.’

[Some considerations about aesthetic medicine].
Ferreira, Francisco Romão
2010-01-01
In this article, we will discuss some aspects of the construction of the meanings concerning the body from the scientific speech which was modeled based on modern thinking and became the hegemonic thinking of some sectors of the medical field. Meanings attributed to the body bring questions that come from other areas of the social life and those questions will build the aesthetic parameters which will be part of the identity construction, in the relation with the body itself, subjectivity and healthcare. We will describe some moments of the construction of the modern scientific thought and how this thought became hegemonic, influences the common sense, naturalizes identity construction and how dealing with the body, interferes in the healthcare, show a division among some sectors of the biomedicine, reinforce an specific type of medical rationality and makes an epistemic base and principle (theoretical and discursive) to some sectors connected to aesthetic medicine and aesthetic surgeries.

We consider the classical evolution of a particle on a graph by using a time-continuous Frobenius-Perron operator that generalizes previous propositions. In this way, the relaxation rates as well as the chaotic properties can be defined for the time-continuous classical dynamics on graphs. These properties are given as the zeros of some periodic-orbit zeta functions. We consider in detail the case of infinite periodic graphs where the particle undergoes a diffusion process. The infinite spatial extension is taken into account by Fourier transforms that decompose the observables and probability densities into sectors corresponding to different values of the wave number. The hydrodynamic modes of diffusion are studied by an eigenvalue problem of a Frobenius-Perron operator corresponding to a given sector. The diffusion coefficient is obtained from the hydrodynamic modes of diffusion and has the Green-Kubo form. Moreover, we study finite but large open graphs that converge to the infinite periodic graph when their size goes to infinity. The lifetime of the particle on the open graph is shown to correspond to the lifetime of a system that undergoes a diffusion process before it escapes

The time has now come when graph theory should be part of the education of every serious student of mathematics and computer science, both for its own sake and to enhance the appreciation of mathematics as a whole. This book is an in-depth account of graph theory, written with such a student in mind; it reflects the current state of the subject and emphasizes connections with other branches of pure mathematics. The volume grew out of the author's earlier book, Graph Theory -- An Introductory Course, but its length is well over twice that of its predecessor, allowing it to reveal many exciting new developments in the subject. Recognizing that graph theory is one of several courses competing for the attention of a student, the book contains extensive descriptive passages designed to convey the flavor of the subject and to arouse interest. In addition to a modern treatment of the classical areas of graph theory such as coloring, matching, extremal theory, and algebraic graph theory, the book presents a detailed ...

Proxy Graph: Visual Quality Metrics of Big Graph Sampling.
Nguyen, Quan Hoang; Hong, Seok-Hee; Eades, Peter; Meidiana, Amyra
2017-06-01
Data sampling has been extensively studied for large scale graph mining. Many analyses and tasks become more efficient when performed on graph samples of much smaller size. The use of proxy objects is common in software engineering for analysis and interaction with heavy objects or systems. In this paper, we coin the term 'proxy graph' and empirically investigate how well a proxy graph visualization can represent a big graph. Our investigation focuses on proxy graphs obtained by sampling; this is one of the most common proxy approaches. Despite the plethora of data sampling studies, this is the first evaluation of sampling in the context of graph visualization. For an objective evaluation, we propose a new family of quality metrics for visual quality of proxy graphs. Our experiments cover popular sampling techniques. Our experimental results lead to guidelines for using sampling-based proxy graphs in visualization.

The forming of this sensibility...... in the social context a central issue of aesthetics. Here, is the argument, is the link to an aesthetic education understood as an education of our senses through cultural products which is also a link to a perspective that appears to be absent in present debates on aesthetics in relation to design. Taking up...... is the goal of an aesthetic education.

Defining the Aesthetic(s of Negation in El Techo de la Ballena
Directory of Open Access Journals (Sweden)
Sean Nesselrode
2014-06-01
Full Text Available The radical artist collective El Techo de la Ballena (1961–1968 is primarily remembered as a scandalous, interdisciplinary pioneer of performative public interventions in Venezuela. Yet the group established a contradictory, pluralistic visual aesthetic(s that served as a refusal of the artistic and political hegemony of geometric and kinetic art. This paper examines several case studies to consider El Techo’s complex visual output, which variously draws upon medieval woodcuts, photography and photomontage, and a mode of gestural abstraction that came to be known as informalismo. The group looked to an alternative genealogy of Dada and Surrealist tactics as a means of introducing an arsenal of new artistic strategies that could be adapted to a specifically Venezuelan discourse of development and disillusion. By advancing a visual language of unpredictability and mutability, El Techo actively refused to achieve a singular identity, its deliberate dissonances complementing its guerrilla approach to artmaking and ultimately seeking to undo the perceived academicism of dominant visualities in Venezuelan art and politics.

Full Text Available In this paper, we review and critically evaluate George D. Birkhoff’s work concerning formalisation of aesthetics, as it appeared in his book Aaesthetic Measure from 1933, and discuss its influence on further research in the field. In the book, Birkhoff defines an aesthetic measure M of an art object as the ratio between its order and complexity, or more generally a function f of this ratio: M = f (OC , where O stands for order and C for complexity. The specific definitions of O and C depend on the type of the analysed object. Birkhoff applied the formula to multiple classes of objects (e.g. vases, music, or English poetry and calculated the aesthetic measure for many art objects from these classes. We give an example of Birkhoff’s analysis using polygons, and we further discuss to what extent the ordering of the polygons (or other objects according to the resulting measures can be used, or interpreted, as an ordering according to a degree of aesthetic preference. We also include an extensive bibliography, supplemented by a critical discussion of the influence of Birkhoff’s work on further research.

[Patients' decision for aesthetic surgery].
Fansa, H; Haller, S
2011-12-01
Aesthetic surgery is a service which entails a high degree of trust. Service evaluation prior to provision is difficult for the patient. This leads to the question of how to manage the service successfully while still focusing on the medical needs. The decision to undergo an operation is not influenced by the operation itself, but by preoperative events which induce the patient to have the operation done. According to "buying decisions" for products or in service management, the decision for an aesthetic operation is extensive; the patient is highly involved and actively searching for information using different directed sources of information. The real "buying decision" consists of 5 phases: problem recognition, gathering of information, alternative education, purchase decision, and post purchase behaviour. A retrospective survey of 40 female patients who have already undergone an aesthetic operation assessed for problem recognition, which types of information were collected prior to the appointment with the surgeon, and why the patients have had the operation at our hospital. They were also asked how many alternative surgeons they had been seen before. Most of the patients had been thinking about undergoing an operation for several years. They mainly used the web for their research and were informed by other (non-aesthetic) physicians/general practitioners. Requested information was about the aesthetic results and possible problems and complications. Patients came based on web information and because of recommendations from other physicians. 60% of all interviewees did not see another surgeon and decided to have the operation because of positive patient-doctor communication and the surgeon's good reputation. Competence was considered to be the most important quality of the surgeon. However, the attribute was judged on subjective parameters. Environment, office rooms and staff were assessed as important but not very important. Costs of surgery were ranked second
Aesthetic aspects in meaning making - an explorative study of dance education in a PETE programme
Directory of Open Access Journals (Sweden)
Suzanne Lundvall
2010-12-01
Full Text Available The article focuses on how aesthetic aspects of experience are involved in meaning making within an educational setting of body movement practice. The study explores stories of how physical education student teachers feel when participating in a dance lesson, with attention given to aesthetic aspects of embodied experiences in relation to meaning making. The study draws on Dewey’s theory of experimental learning. Aesthetic experience is defined as the feeling of wholeness or fulfilment in the transaction taking place. The categorical analysis of content, inspired by pragmatic epistemology analyses, uses the operational concepts of gaps, encounters, and relations. Three categories of stories emerge linked by the resemblance of positive or negative feelings expressed. The aesthetic experiences seem to inform the students of the purpose of what is undertaken, how to value the experience, and how the meaning of the embodied experience is perceived.

Study 2 investigated how contemporary East Asians and Westerners draw landscape pictures and take portrait photographs. Study 3 further investigated aesthetic preferences for portrait photographs. The results suggest that (a) traditional East Asian art has predominantly context-inclusive styles, whereas Western art has predominantly object-focused styles, and (b) contemporary members of East Asian and Western cultures maintain these culturally shaped aesthetic orientations. The findings can be explained by the relation among attention, cultural resources, and aesthetic preference.
Magic and the aesthetic illusion.
Balter, Leon
2002-01-01
The aesthetic illusion is the subjective experience that the content of a work of art is reality. It has an intrinsic relation to magic, an intrapsychic maneuver oriented toward modification and control of the extraspyschic world, principally through ego functioning. Magic is ontogenetically and culturally archaic, expresses the omnipotence inherent in primary narcissism, and operates according to the logic of the primary process. Magic is a constituent of all ego functioning, usually latent in later development. It may persist as an archaic feature or may be evoked regressively in global or circumscribed ways. It causes a general disinhibition of instincts and impulses attended by a sense of confidence, exhiliration, and exuberance. The aesthetic illusion is a combination of illusions: (1) that the daydream embodied by the work of art is the beholder's own, the artist being ignored, and (2) that the artistically described protagonist is a real person with a real "world." The first illusion arises through the beholder's emotional-instinctual gratification from his or her own fantasy-memory constellations; the second comes about because the beholder, by taking the protagonist as proxy, mobilizes the subjective experience of the imaginary protagonist's "reality." The first illusion is necessary for the second to take place; the second establishes the aesthetic illusion proper. Both illusions are instances of magic. Accordingly, the aesthetic illusion is accompanied by a heady experience of excitement and euphoria. The relation among the aesthetic illusion, magic, and enthusiasm is illustrated by an analytic case, J. D. Salinger's "The Laughing Man," Woody Allen's Play It Again, Sam, Don Quixote, and the medieval Cult of the Saints.
Coevolutionary aesthetics in human and biotic artworlds.
Prum, Richard O
2013-01-01
This work proposes a coevolutionary theory of aesthetics that encompasses both biotic and human arts. Anthropocentric perspectives in aesthetics prevent the recognition of the ontological complexity of the aesthetics of nature, and the aesthetic agency of many non-human organisms. The process of evaluative coevolution is shared by all biotic advertisements. I propose that art consists of a form of communication that coevolves with its own evaluation. Art and art history are population phenomena. I expand Arthur Danto's Artworld concept to any aesthetic population of producers and evaluators. Current concepts of art cannot exclusively circumscribe the human arts from many forms of non-human biotic art. Without assuming an arbitrarily anthropocentric perspective, any concept of art will need to engage with biodiversity, and either recognize many instances of biotic advertisements as art, or exclude some instances of human art. Coevolutionary aesthetic theory provides a heuristic account of aesthetic change in both human and biotic artworlds, including the coevolutionary origin of aesthetic properties and aesthetic value within artworlds. Restructuring aesthetics, art criticism, and art history without human beings at the organizing centers of these disciplines stimulate new progress in our understanding of art, and the unique human contributions to aesthetics and aesthetic diversity.

Fundamentals of algebraic graph transformation
Ehrig, Hartmut; Prange, Ulrike; Taentzer, Gabriele
2006-01-01
Graphs are widely used to represent structural information in the form of objects and connections between them. Graph transformation is the rule-based manipulation of graphs, an increasingly important concept in computer science and related fields. This is the first textbook treatment of the algebraic approach to graph transformation, based on algebraic structures and category theory. Part I is an introduction to the classical case of graph and typed graph transformation. In Part II basic and advanced results are first shown for an abstract form of replacement systems, so-called adhesive high-level replacement systems based on category theory, and are then instantiated to several forms of graph and Petri net transformation systems. Part III develops typed attributed graph transformation, a technique of key relevance in the modeling of visual languages and in model transformation. Part IV contains a practical case study on model transformation and a presentation of the AGG (attributed graph grammar) tool envir...
The STAPL Parallel Graph Library
Harshvardhan,
2013-01-01
This paper describes the stapl Parallel Graph Library, a high-level framework that abstracts the user from data-distribution and parallelism details and allows them to concentrate on parallel graph algorithm development. It includes a customizable distributed graph container and a collection of commonly used parallel graph algorithms. The library introduces pGraph pViews that separate algorithm design from the container implementation. It supports three graph processing algorithmic paradigms, level-synchronous, asynchronous and coarse-grained, and provides common graph algorithms based on them. Experimental results demonstrate improved scalability in performance and data size over existing graph libraries on more than 16,000 cores and on internet-scale graphs containing over 16 billion vertices and 250 billion edges. © Springer-Verlag Berlin Heidelberg 2013.

The field of topological graph theory has expanded greatly in the ten years since the first edition of this book appeared. The original nine chapters of this classic work have therefore been revised and updated. Six new chapters have been added, dealing with: voltage graphs, non-orientable imbeddings, block designs associated with graph imbeddings, hypergraph imbeddings, map automorphism groups and change ringing.Thirty-two new problems have been added to this new edition, so that there are now 181 in all; 22 of these have been designated as ``difficult'''' and 9 as ``unsolved''''. Three of the four unsolved problems from the first edition have been solved in the ten years between editions; they are now marked as ``difficult''''.

Let (G,w) be a weighted graph. We find necessary and sufficient conditions under which the weight w:E(G)→R{sup +} can be extended to a pseudoultrametric on V(G), and establish a criterion for the uniqueness of such an extension. We demonstrate that (G,w) is a complete k-partite graph, for k≥2, if and only if for any weight that can be extended to a pseudoultrametric, among all such extensions one can find the least pseudoultrametric consistent with w. We give a structural characterization of graphs for which the subdominant pseudoultrametric is an ultrametric for any strictly positive weight that can be extended to a pseudoultrametric. Bibliography: 14 titles.

The implementation of art education in nursing is said to have positive effects on nursing students. Most studies applied visual art dialogues or object design, whereas the effectiveness of drawing as a teaching and learning method is rarely examined and discussed. This paper aimed to discuss the potential and effectiveness of drawing as a learning and teaching method. Four drawings which were created by Hong Kong nursing students are demonstrated and the students' perspectives of how drawing enhanced learning are shown in this paper. Topics on drawing as a fun teaching and learning method and the way it can enhance critical thinking and creativity are also discussed. In conclusion, the activity was a great success, and students enjoyed the learning process and reflected positive comments. However, we cannot conclude that drawing is an effective teaching and learning method based on a single paper, therefore more similar studies should be conducted to investigate this method.

Drawing Theory. An Introduction
Directory of Open Access Journals (Sweden)
Stefano Milani
2014-08-01
Full Text Available Nowadays, drawing practices seem to operate in a rather uncertain field that is typical of an in-between phase of disciplinary development and that needs to be addressed, if an ‘anticipated projection’ of the development of drawing is to be attempted. The field of drawing, as practice and discourse, seems to have entered an end-condition, where the celebration of the extensive production of drawings is combined with a certain fatigue in both its understanding and reflection. Even though the role of drawing is nowadays still regarded as the most common act of architecture, this understanding of drawing is hardly subject to critical inquiries, and, unfortunately, mostly limited to its instrumental role within the representation of the project.A common characteristic in all of the papers in this issue of Footprint is that a specific character of the theoretical field generated by drawing is the elaboration of the correlation between two epistemic regions. This singular character probably belongs to drawing’s structural duality of being simultaneously a simulacrum of a reality and reality itself, memory and anticipation, subject and object, by being in essence the measure of two different facets inherent to architectural thinking. Drawing not only gives consistency to the poles, rendering them architectural matter, but also literally (reconstructs them. At the same time, drawing formalizes the theoretical distance between the two.

Using Graph and Vertex Entropy to Compare Empirical Graphs with Theoretical Graph Models
Directory of Open Access Journals (Sweden)
Tomasz Kajdanowicz
2016-09-01
Full Text Available Over the years, several theoretical graph generation models have been proposed. Among the most prominent are: the Erdős–Renyi random graph model, Watts–Strogatz small world model, Albert–Barabási preferential attachment model, Price citation model, and many more. Often, researchers working with real-world data are interested in understanding the generative phenomena underlying their empirical graphs. They want to know which of the theoretical graph generation models would most probably generate a particular empirical graph. In other words, they expect some similarity assessment between the empirical graph and graphs artificially created from theoretical graph generation models. Usually, in order to assess the similarity of two graphs, centrality measure distributions are compared. For a theoretical graph model this means comparing the empirical graph to a single realization of a theoretical graph model, where the realization is generated from the given model using an arbitrary set of parameters. The similarity between centrality measure distributions can be measured using standard statistical tests, e.g., the Kolmogorov–Smirnov test of distances between cumulative distributions. However, this approach is both error-prone and leads to incorrect conclusions, as we show in our experiments. Therefore, we propose a new method for graph comparison and type classification by comparing the entropies of centrality measure distributions (degree centrality, betweenness centrality, closeness centrality. We demonstrate that our approach can help assign the empirical graph to the most similar theoretical model using a simple unsupervised learning method.

Coloring geographical threshold graphs
Energy Technology Data Exchange (ETDEWEB)
Bradonjic, Milan [Los Alamos National Laboratory; Percus, Allon [Los Alamos National Laboratory; Muller, Tobias [EINDHOVEN UNIV. OF TECH
2008-01-01
We propose a coloring algorithm for sparse random graphs generated by the geographical threshold graph (GTG) model, a generalization of random geometric graphs (RGG). In a GTG, nodes are distributed in a Euclidean space, and edges are assigned according to a threshold function involving the distance between nodes as well as randomly chosen node weights. The motivation for analyzing this model is that many real networks (e.g., wireless networks, the Internet, etc.) need to be studied by using a 'richer' stochastic model (which in this case includes both a distance between nodes and weights on the nodes). Here, we analyze the GTG coloring algorithm together with the graph's clique number, showing formally that in spite of the differences in structure between GTG and RGG, the asymptotic behavior of the chromatic number is identical: {chi}1n 1n n / 1n n (1 + {omicron}(1)). Finally, we consider the leading corrections to this expression, again using the coloring algorithm and clique number to provide bounds on the chromatic number. We show that the gap between the lower and upper bound is within C 1n n / (1n 1n n){sup 2}, and specify the constant C.

In very simple terms a network can be de ned as a collection of points joined together by lines. Thus, networks can be used to represent connections between entities in a wide variety of elds including engi- neering, science, medicine, and sociology. Many large real-world networks share a surprising number of properties, leading to a strong interest in model development research and techniques for building synthetic networks have been developed, that capture these similarities and replicate real-world graphs. Modeling these real-world networks serves two purposes. First, building models that mimic the patterns and prop- erties of real networks helps to understand the implications of these patterns and helps determine which patterns are important. If we develop a generative process to synthesize real networks we can also examine which growth processes are plausible and which are not. Secondly, high-quality, large-scale network data is often not available, because of economic, legal, technological, or other obstacles [7]. Thus, there are many instances where the systems of interest cannot be represented by a single exemplar network. As one example, consider the eld of cybersecurity, where systems require testing across diverse threat scenarios and validation across diverse network structures. In these cases, where there is no single exemplar network, the systems must instead be modeled as a collection of networks in which the variation among them may be just as important as their common features. By developing processes to build synthetic models, so-called graph generators, we can build synthetic networks that capture both the essential features of a system and realistic variability. Then we can use such synthetic graphs to perform tasks such as simulations, analysis, and decision making. We can also use synthetic graphs to performance test graph analysis algorithms, including clustering algorithms and anomaly detection algorithms.

Since automated CAD drawing generation systems still require human intervention, improvements were focussed on an interactive processing section (data input and correcting operation) which necessitates a vast amount of work. As a result, human intervention was eliminated, the original objective of a computerized system. This is the first step taken towards complete automation. The effects of development and commercialization of the system are as described below. (1) The interactive processing time required for generating drawings was improved. It was determined that introduction of the CAD system has reduced the time required for generating drawings. (2) The difference in skills between workers preparing drawings has been eliminated and the quality of drawings has been made uniform. (3) The extent of knowledge and experience demanded of workers has been reduced. (author)
Groupies in multitype random graphs

2016-01-01
A groupie in a graph is a vertex whose degree is not less than the average degree of its neighbors. Under some mild conditions, we show that the proportion of groupies is very close to 1/2 in multitype random graphs (such as stochastic block models), which include Erd?s-R?nyi random graphs, random bipartite, and multipartite graphs as special examples. Numerical examples are provided to illustrate the theoretical results.

A wide range of knowledge discovery and analysis applications, ranging from business to biological, make use of semantic graphs when modeling relationships and concepts. Most of the semantic graphs used in these applications are assumed to be static pieces of information, meaning temporal evolution of concepts and relationships are not taken into account. Guided by the need for more advanced semantic graph queries involving temporal concepts, this paper surveys the existing work involving temporal representations in semantic graphs.
Quantum walks on quotient graphs
International Nuclear Information System (INIS)
Krovi, Hari; Brun, Todd A.
2007-01-01
A discrete-time quantum walk on a graph Γ is the repeated application of a unitary evolution operator to a Hilbert space corresponding to the graph. If this unitary evolution operator has an associated group of symmetries, then for certain initial states the walk will be confined to a subspace of the original Hilbert space. Symmetries of the original graph, given by its automorphism group, can be inherited by the evolution operator. We show that a quantum walk confined to the subspace corresponding to this symmetry group can be seen as a different quantum walk on a smaller quotient graph. We give an explicit construction of the quotient graph for any subgroup H of the automorphism group and illustrate it with examples. The automorphisms of the quotient graph which are inherited from the original graph are the original automorphism group modulo the subgroup H used to construct it. The quotient graph is constructed by removing the symmetries of the subgroup H from the original graph. We then analyze the behavior of hitting times on quotient graphs. Hitting time is the average time it takes a walk to reach a given final vertex from a given initial vertex. It has been shown in earlier work [Phys. Rev. A 74, 042334 (2006)] that the hitting time for certain initial states of a quantum walks can be infinite, in contrast to classical random walks. We give a condition which determines whether the quotient graph has infinite hitting times given that they exist in the original graph. We apply this condition for the examples discussed and determine which quotient graphs have infinite hitting times. All known examples of quantum walks with hitting times which are short compared to classical random walks correspond to systems with quotient graphs much smaller than the original graph; we conjecture that the existence of a small quotient graph with finite hitting times is necessary for a walk to exhibit a quantum speedup

Graph mining has been a popular research area because of its numerous application scenarios. Many unstructured and structured data can be represented as graphs, such as, documents, chemical molecular structures, and images. However, an issue in relation to current research on graphs is that they cannot adequately discover the topics hidden in graph-structured data which can be beneficial for both the unsupervised learning and supervised learning of the graphs. Although topic models have proved to be very successful in discovering latent topics, the standard topic models cannot be directly applied to graph-structured data due to the "bag-of-word" assumption. In this paper, an innovative graph topic model (GTM) is proposed to address this issue, which uses Bernoulli distributions to model the edges between nodes in a graph. It can, therefore, make the edges in a graph contribute to latent topic discovery and further improve the accuracy of the supervised and unsupervised learning of graphs. The experimental results on two different types of graph datasets show that the proposed GTM outperforms the latent Dirichlet allocation on classification by using the unveiled topics of these two models to represent graphs.

structural properties that can be exploited. For instance, a road network or a wire layout on a microchip is typically (near-)planar and distances in the network are often defined w.r.t. the Euclidean or the rectilinear metric. Specialized algorithms that take advantage of such properties are often orders...... of magnitude faster than the corresponding algorithms for general graphs. The first and main part of this thesis focuses on the development of efficient planar graph algorithms. The most important contributions include a faster single-source shortest path algorithm, a distance oracle with subquadratic...... for geometric graphs and graphs embedded in metric spaces. Roughly speaking, the stretch factor is a real value expressing how well a (geo-)metric graph approximates the underlying complete graph w.r.t. distances. We give improved algorithms for computing the stretch factor of a given graph and for augmenting...

Full Text Available Reading is a process of aesthetically appreciative receptive to emphasize critical-creative reading activities. Metacognitively students understand, address any and explore the idea of the author in the text. Students responded, criticize, and evaluate the author's ideas in the text. At this stage, students can construct their post read text into other forms (new text. The aim of this strategy equips students to understand the meaning of the story, explore ideas, responding critically, and creatively pouring backstory idea. Reading strategies aesthetically-critical-creative receptive grabbed cognitive, effective, and psychomotor toward literacy critical reading and creative writing. Read appreciative included into the activities of reading comprehension. This activity involves the sensitivity and ability to process aesthetically-receptive reading and critical-creative. Readers imagination roam the author to obtain meaningful understanding and experience of reading. Some models of reading comprehension proposed experts covering the steps before reading, when reading, and after reading. At that stage to enable students after reading thinking abilities. Activities that can be done at this stage, for example, examine the back story, retell, make drawings, diagrams, or maps the concept of reading, as well as making a road map that describes the event. Other activities that can be done is to transform our student's text stories through reinforcement form illustrated stories into comic book form, for example (transliteration.
Literary aesthetics: beauty, the brain, and Mrs. Dalloway.
Hogan, Patrick Colm
2013-01-01
Empirical research indicates that beauty is in part a matter of prototype approximation. Some research suggests that unanticipated pattern recognition is important as well. This essay begins by briefly outlining an account of beauty based on these factors. It goes on to consider complications. Minor complications include the partial incompatibility of these accounts and the importance of differentiating judgments of beauty from aesthetic response. More serious issues include the relative neglect of literature in neurologically-based discussions of beauty, which tend to focus on music or visual art. There is also a relative neglect of emotion, beyond the reward system. Finally, there is the almost complete absence of the sublime. After considering these problems broadly, the essay turns to Virginia Woolf's Mrs. Dalloway, examining its treatment of beauty and sublimity. The aim of this section is not merely to illuminate Woolf's novel by reference to neuroscientific research. It is equally, perhaps more fully, to expand our neuroscientifically grounded account of aesthetic response by drawing on Woolf's novel. In Mrs. Dalloway, there are gestures toward prototypes and patterns in beauty. But the key features are clearly emotional. Specifically, the emotions at issue in feelings of beauty and sublimity appear to be primarily attachment, on the one hand, and a profound sense of isolation, on the other. Woolf's novel also points us toward other features of aesthetic experience, crucially including the emotion-sharing that is a key function of the production and circulation of art. © 2013 Elsevier B.V.

Aesthetic Engagement, Ecosophy C, and Ecological Appreciation
Directory of Open Access Journals (Sweden)
Cheng Xiangzhan

Full Text Available With the aim of healing the earth and sustain a healthy ecosystem for all life forms, not humankind alone, ecoaesthetics emerges as a critique of Enlightenment mentality and of modern aesthetics as it is embodied in it. This mentality contributes greatly to the global ecological crisis and to other problem areas, such as population, economic, political and religious ones. In my understanding of aesthetics, ecoaesthetics is defined as the theory of ecological aesthetic appreciation.[1] With ecoaesthetics as my research horizon, there are at least two reasons for me to pay special attention to American philosopher Arnold Berleant’s conception of aesthetic engagement and his aesthetic theory based on it, an aesthetics of engagement. The first is our shared theme, which is the critique of modern aesthetics. The second reason is more complex for it involves the crucial question of the proper manner of aesthetic appreciation. From the perspective of ecoaesthetics, the contemplation of objects by a separated perceiver, an approach that is based on the modern philosophical dualism of subject and object, is unsatisfactory and inadequate. Berleant’s aesthetic engagement is a more satisfactory account of appreciation that is aesthetic and ecological. This emphasizes the ecological continuity or interrelatedness between the human appreciator and objects. Of course, any theory can occasion critique and development. Based on Berleant’s idea of aesthetic engagement, I would like to propose Ecosophy C. This can be contrasted with Ecosophy T proposed by the Norwegian, Arne Naess, and with traditional Chinese aesthetic wisdom. In contrast with these, I would like to develop my own view of ecological understanding. In order to construct a more comprehensive and reasonable ecoaesthetics, my Ecosophy C contains eight points that are crucial in building an ecological model of aesthetic appreciation for this period of ecological crisis.

We prove the Bohigas-Giannoni-Schmit conjecture in its most general form for completely connected simple graphs with incommensurate bond lengths. We show that for graphs that are classically mixing (i.e., graphs for which the spectrum of the classical Perron-Frobenius operator possesses a finite gap), the generating functions for all (P,Q) correlation functions for both closed and open graphs coincide (in the limit of infinite graph size) with the corresponding expressions of random-matrix theory, both for orthogonal and for unitary symmetry

2015-07-01
Full Text Available A connected dominating set is an important notion and has many applications in routing and management of networks. Graph products have turned out to be a good model of interconnection networks. This motivated us to study the Cartesian product of graphs G with connected domination number, γc(G=2,3 and characterize such graphs. Also, we characterize the k−γ-vertex (edge critical graphs and k−γc-vertex (edge critical graphs for k=2,3 where γ denotes the domination number of G. We also discuss the vertex criticality in grids.
Graph Creation, Visualisation and Transformation

Full Text Available We describe a tool to create, edit, visualise and compute with interaction nets - a form of graph rewriting systems. The editor, called GraphPaper, allows users to create and edit graphs and their transformation rules using an intuitive user interface. The editor uses the functionalities of the TULIP system, which gives us access to a wealth of visualisation algorithms. Interaction nets are not only a formalism for the specification of graphs, but also a rewrite-based computation model. We discuss graph rewriting strategies and a language to express them in order to perform strategic interaction net rewriting.

Graph Sampling for Covariance Estimation
Chepuri, Sundeep Prabhakar
2017-04-25
In this paper the focus is on subsampling as well as reconstructing the second-order statistics of signals residing on nodes of arbitrary undirected graphs. Second-order stationary graph signals may be obtained by graph filtering zero-mean white noise and they admit a well-defined power spectrum whose shape is determined by the frequency response of the graph filter. Estimating the graph power spectrum forms an important component of stationary graph signal processing and related inference tasks such as Wiener prediction or inpainting on graphs. The central result of this paper is that by sampling a significantly smaller subset of vertices and using simple least squares, we can reconstruct the second-order statistics of the graph signal from the subsampled observations, and more importantly, without any spectral priors. To this end, both a nonparametric approach as well as parametric approaches including moving average and autoregressive models for the graph power spectrum are considered. The results specialize for undirected circulant graphs in that the graph nodes leading to the best compression rates are given by the so-called minimal sparse rulers. A near-optimal greedy algorithm is developed to design the subsampling scheme for the non-parametric and the moving average models, whereas a particular subsampling scheme that allows linear estimation for the autoregressive model is proposed. Numerical experiments on synthetic as well as real datasets related to climatology and processing handwritten digits are provided to demonstrate the developed theory.
A gray matter of taste: sound perception, music cognition, and Baumgarten's aesthetics.
Pannese, Alessia
2012-09-01
Music is an ancient and ubiquitous form of human expression. One important component for which music is sought after is its aesthetic value, whose appreciation has typically been associated with largely learned, culturally determined factors, such as education, exposure, and social pressure. However, neuroscientific evidence shows that the aesthetic response to music is often associated with automatic, physically- and biologically-grounded events, such as shivers, chills, increased heart rate, and motor synchronization, suggesting the existence of an underlying biological platform upon which contextual factors may act. Drawing on philosophical notions and neuroscientific evidence, I argue that, although there is no denying that social and cultural context play a substantial role in shaping the aesthetic response to music, these act upon largely universal, biological mechanisms involved with neural processing. I propose that the simultaneous presence of culturally-influenced and biologically-determined contributions to the aesthetic response to music epitomizes Baumgarten's equation of sensory perception with taste. Taking the argument one step further, I suggest that the heavily embodied aesthetic response to music bridges the cleavage between the two discrepant meanings-the one referring to sensory perception, the other referring to judgments of taste-traditionally attributed to the word "aesthetics" in the sciences and the humanities.

Practical Graph Mining with R presents a "do-it-yourself" approach to extracting interesting patterns from graph data. It covers many basic and advanced techniques for the identification of anomalous or frequently recurring patterns in a graph, the discovery of groups or clusters of nodes that share common patterns of attributes and relationships, the extraction of patterns that distinguish one category of graphs from another, and the use of those patterns to predict the category of new graphs. Hands-On Application of Graph Data Mining Each chapter in the book focuses on a graph mining task, such as link analysis, cluster analysis, and classification. Through applications using real data sets, the book demonstrates how computational techniques can help solve real-world problems. The applications covered include network intrusion detection, tumor cell diagnostics, face recognition, predictive toxicology, mining metabolic and protein-protein interaction networks, and community detection in social networks.

Canonical Labelling of Site Graphs
Directory of Open Access Journals (Sweden)
Nicolas Oury
2013-06-01
Full Text Available We investigate algorithms for canonical labelling of site graphs, i.e. graphs in which edges bind vertices on sites with locally unique names. We first show that the problem of canonical labelling of site graphs reduces to the problem of canonical labelling of graphs with edge colourings. We then present two canonical labelling algorithms based on edge enumeration, and a third based on an extension of Hopcroft's partition refinement algorithm. All run in quadratic worst case time individually. However, one of the edge enumeration algorithms runs in sub-quadratic time for graphs with "many" automorphisms, and the partition refinement algorithm runs in sub-quadratic time for graphs with "few" bisimulation equivalences. This suite of algorithms was chosen based on the expectation that graphs fall in one of those two categories. If that is the case, a combined algorithm runs in sub-quadratic worst case time. Whether this expectation is reasonable remains an interesting open problem.

Effective information analysis generally boils down to properly identifying the structure or geometry of the data, which is often represented by a graph. In some applications, this structure may be partly determined by design constraints or pre-determined sensing arrangements, like in road transportation networks for example.

The purpose of a comprehensive content analysis of print advertising is to determine whether the items indicated by evolutionists such as animals, flowers, certain types of landscapes, beautiful humans, and some colors are part of real advertising strategies. This article has shown that many evolutionary hypotheses (although not all of them are supported by empirical data. Along with these hypotheses, some inferences from Bourdieu’s cultural capital theory were tested. It turned out that advertising uses both biological schemata and cultural patterns to make an image more likable.

To assess the psychosocial impact of dental aesthetics using the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ) and self-rated Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Cross-sectional study. Dental Section, the Aga Khan University Hospital, Karachi, from August to September 2006. Adults with no prior orthodontic treatment were asked to complete a modified version of the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ). A total of four variables including 'Dental Self-confidence', 'Social impact', 'Psychological impact' and 'Perceived orthodontic treatment need' were assessed by a series of statements, whereas dental aesthetics were assessed by the respondents using the IOTN Aesthetic Component (self-rated IOTN-AC). Kruskal-Walli's test was applied to determine significance. The respondents were 120 adults (70 females and 50 males; mean age 25.8 years), all four of the above-mentioned variables measuring psychosocial impact showed positive and significant correlations with the perceived severity of malocclusion as depicted by the Aesthetic Component (AC) of Index of Orthodontic Treatment Need (IOTN), with p-value of less than 0.01 for all variables. The results indicate the strong psychosocial impact of altered dental aesthetics on the emotional state of an individual. The association between self-rated IOTN-AC grading with psychosocial well-being stands established, indicating that the perceived aesthetics of malocclusion may be as significant a factor in determining treatment need as the degree of malocclusion.

Headache in children's drawings.

2008-02-01
Headache is a common health problem in childhood. Children's drawings are helpful in the diagnosis of headache type. Children, especially younger ones, communicate better through pictures than verbally. The aim of the present study is to evaluate the usefulness of drawings of the child's headache in the diagnostic process carried out by a pediatrician and a pediatric neurologist. At the beginning of a visit in a neurological clinic, or on the first day of hospitalization, the child was asked, "Please draw your headache," or "How do you feel your headache?" without any additional explanations or suggestions. Clinical diagnosis of headache type was made on the basis of the standard diagnostic evaluation. For the purpose of this study, children's headaches were categorized as migraine, tension-type headache, or "the others." One hundred twenty-four drawings of children with headaches were analyzed by 8 pediatricians and 8 pediatric neurologists. The analysts were unaware of the clinical history, age, sex, and diagnosis of the patients. The clinical diagnosis was considered the "gold standard" to which the headache drawing diagnosis was compared. There were 68 girls 5-18 years of age and 56 boys 7-18 years of age. Of the 124 children, 40 were clinically diagnosed with migraine (32.2%), 47 with tension-type headache (37.9%), and 37 (29.8%) as the others. Children with migraine most frequently draw sharp elements. Children with tension-type headache mainly drew compression elements and pressing elements. In the group of "the other" headaches, 21 children were diagnosed with somatoform disorders. The most frequent element in this group's drawings was a whirl in the head. Colors used most frequently were black and red, which signify severe pain. There was no difference in sensitivity of diagnoses between neurologists and pediatricians. Because the evaluation of drawings by children with headaches done both by pediatricians and pediatric neurologists was correct for

Here we study graphs with the same adjacency spectrum as the $F_n$. Two graphs are called cospectral if the eigenvalues multiset of their adjacency matrices are the same. Let $G$ be a graph cospectral with $F_n$. Here we prove that if $G$ has no cycle of length $4$ or $5$, then $Gcong F_n$. Moreover if $G$ is connected and planar then $Gcong F_n$.All but one of connected components of $G$ are isomorphic to $K_2$.The complement $overline{F_n}$ of the friendship graph is determined by its adjacency eigenvalues, that is, if $overline{F_n}$ is cospectral with a graph $H$, then $Hcong overline{F_n}$.

Computational and Experimental Approaches to Visual Aesthetics
Brachmann, Anselm; Redies, Christoph
2017-01-01
Aesthetics has been the subject of long-standing debates by philosophers and psychologists alike. In psychology, it is generally agreed that aesthetic experience results from an interaction between perception, cognition, and emotion. By experimental means, this triad has been studied in the field of experimental aesthetics, which aims to gain a better understanding of how aesthetic experience relates to fundamental principles of human visual perception and brain processes. Recently, researchers in computer vision have also gained interest in the topic, giving rise to the field of computational aesthetics. With computing hardware and methodology developing at a high pace, the modeling of perceptually relevant aspect of aesthetic stimuli has a huge potential. In this review, we present an overview of recent developments in computational aesthetics and how they relate to experimental studies. In the first part, we cover topics such as the prediction of ratings, style and artist identification as well as computational methods in art history, such as the detection of influences among artists or forgeries. We also describe currently used computational algorithms, such as classifiers and deep neural networks. In the second part, we summarize results from the field of experimental aesthetics and cover several isolated image properties that are believed to have a effect on the aesthetic appeal of visual stimuli. Their relation to each other and to findings from computational aesthetics are discussed. Moreover, we compare the strategies in the two fields of research and suggest that both fields would greatly profit from a joined research effort. We hope to encourage researchers from both disciplines to work more closely together in order to understand visual aesthetics from an integrated point of view. PMID:29184491

Aesthetic criteria for designs are often debated in a very subjective manner which makes it difficult to reach consensus. In order to have a more rational and transparent process, in particular in industrial design, we propose a procedure based on Baumgarten's aesthetic considerations and Thommesen......'s dividing of a form into form elements.

[Exploration of nursing art and aesthetic experiences: cross-disciplinary links and dialogues].
Sheu, Shuh-Jen
2013-08-01
Interdisciplinary understanding is crucial for readers today. This article integrates the ideas of four care-aesthetics-column writers in order to illustrate and discuss nursing art and aesthetic care experiences in a cross-disciplinary conversation. This article reflects critically on the art, culture, and nature of nursing in the five themes of: 1) the shape of nursing knowledge, "science" or "art"?; 2) the caring arts: passively regulative or consciously creative labor?; 3) busy hospital workers: a landscape of persons and objects or the creators of the scenery?; 4) nursing skills, arts, and the Tao; and 5) art liberation: is the nursing profession in need of a revolution or fundamental reform? This article utilizes diverse and occasionally contradictory points of view together with practical examples in order to encourage readers to interlink their disparate professional nursing skills and draw aesthetic knowledge from multiple sources and experiences.
Optimization Problems on Threshold Graphs

Full Text Available During the last three decades, different types of decompositions have been processed in the field of graph theory. Among these we mention: decompositions based on the additivity of some characteristics of the graph, decompositions where the adjacency law between the subsets of the partition is known, decompositions where the subgraph induced by every subset of the partition must have predeterminate properties, as well as combinations of such decompositions. In this paper we characterize threshold graphs using the weakly decomposition, determine: density and stability number, Wiener index and Wiener polynomial for threshold graphs.

They should appeal both to researchers and students, as they contain enough material for an undergraduate or graduate graph theory course which emphasizes Eulerian graphs, and thus can be read by any mathematician not yet familiar with graph theory. But they are also of interest to researchers in graph theory because they contain many recent results, some of which are only partial solutions to more general problems. A number of conjectures have been included as well. Various problems (such a

In recent years, advanced network analytics have become increasingly important to na- tional security with applications ranging from cyber security to detection and disruption of ter- rorist networks. While classical computing solutions have received considerable investment, the development of quantum algorithms to address problems, such as data mining of attributed relational graphs, is a largely unexplored space. Recent theoretical work has shown that quan- tum algorithms for graph analysis can be more efficient than their classical counterparts. Here, we have implemented a trapped-ion-based two-qubit quantum information proces- sor to address these goals. Building on Sandia's microfabricated silicon surface ion traps, we have designed, realized and characterized a quantum information processor using the hyperfine qubits encoded in two 171 Yb + ions. We have implemented single qubit gates using resonant microwave radiation and have employed Gate set tomography (GST) to characterize the quan- tum process. For the first time, we were able to prove that the quantum process surpasses the fault tolerance thresholds of some quantum codes by demonstrating a diamond norm distance of less than 1 . 9 x 10 [?] 4 . We used Raman transitions in order to manipulate the trapped ions' motion and realize two-qubit gates. We characterized the implemented motion sensitive and insensitive single qubit processes and achieved a maximal process infidelity of 6 . 5 x 10 [?] 5 . We implemented the two-qubit gate proposed by Molmer and Sorensen and achieved a fidelity of more than 97 . 7%.

Bernard Tschumi Draws Architecture!
Directory of Open Access Journals (Sweden)
Gevork Hartoonian
2014-08-01
Full Text Available Bernard Tschumi’s delineation prepared for the Museu de Arte Contemporânea provides the starting point for this essay, which discusses the historicity of drawing and highlights the horizontality and the verticality that structure architecture’s contrast with the pictorial realm. Juxtaposing a freehand sketch with the digital image of the same project, Tschumi moves to address the paradox concerning the position of the body and drawing. This drawing also speaks for the reversal in the position of the body brought about by digital reproductivity.The reversal alludes to Tschumi’s theorization of architecture in terms of space and event. These, I will argue, are anticipated in The Manhattan Transcripts (1981 where a set of freehand drawings is used to evoke a filmic mood wherein the image is projected parallel to the spectator’s seated position. The essay goes further, suggesting that the theatricality permeating the present architecture is part of the shift from horizontality to the painterly, and yet the phenomenon is not merely a technical issue. Rather, it alludes to architecture’s dialogical rapport with painting at work since the Renaissance.

Full Text Available Graphing function is an important issue in mathematics education due to its use in various areas of mathematics and its potential roles for students to enhance learning mathematics. The use of some graphing software assists students’ learning during graphing functions. However, the display of graphs of functions that students sketched by hand may be relatively different when compared to the correct forms sketched using graphing software. The possible misleading effects of this situation brought a discussion of a misconception (asymptote misconception on graphing functions. The purpose of this study is two- fold. First of all, this study investigated whether using graphing software (GeoGebra in this case helps students to determine and resolve this misconception in calculus classrooms. Second, the reasons for this misconception are sought. The multiple case study was utilized in this study. University students in two calculus classrooms who received instructions with (35 students or without GeoGebra assisted instructions (32 students were compared according to whether they fell into this misconception on graphing basic functions (1/x, lnx, ex. In addition, students were interviewed to reveal the reasons behind this misconception. Data were analyzed by means of descriptive and content analysis methods. The findings indicated that those who received GeoGebra assisted instruction were better in resolving it. In addition, the reasons behind this misconception were found to be teacher-based, exam-based and some other factors.

Graph Theory. 2. Vertex Descriptors and Graph Coloring
Directory of Open Access Journals (Sweden)
Lorentz JÄNTSCHI
2002-12-01
Full Text Available This original work presents the construction of a set of ten sequence matrices and their applications for ordering vertices in graphs. For every sequence matrix three ordering criteria are applied: lexicographic ordering, based on strings of numbers, corresponding to every vertex, extracted as rows from sequence matrices; ordering by the sum of path lengths from a given vertex; and ordering by the sum of paths, starting from a given vertex. We also examine a graph that has different orderings for the above criteria. We then proceed to demonstrate that every criterion induced its own partition of graph vertex. We propose the following theoretical result: both LAVS and LVDS criteria generate identical partitioning of vertices in any graph. Finally, a coloring of graph vertices according to introduced ordering criteria was proposed.
On an edge partition and root graphs of some classes of line graphs
Directory of Open Access Journals (Sweden)
K Pravas
2017-04-01
Full Text Available The Gallai and the anti-Gallai graphs of a graph $G$ are complementary pairs of spanning subgraphs of the line graph of $G$. In this paper we find some structural relations between these graph classes by finding a partition of the edge set of the line graph of a graph $G$ into the edge sets of the Gallai and anti-Gallai graphs of $G$. Based on this, an optimal algorithm to find the root graph of a line graph is obtained. Moreover, root graphs of diameter-maximal, distance-hereditary, Ptolemaic and chordal graphs are also discussed.

Bell inequalities for graph states
International Nuclear Information System (INIS)
Toth, G.; Hyllus, P.; Briegel, H.J.; Guehne, O.
2005-01-01
Full text: In the last years graph states have attracted an increasing interest in the field of quantum information theory. Graph states form a family of multi-qubit states which comprises many popular states such as the GHZ states and the cluster states. They also play an important role in applications. For instance, measurement based quantum computation uses graph states as resources. From a theoretical point of view, it is remarkable that graph states allow for a simple description in terms of stabilizing operators. In this contribution, we investigate the non-local properties of graph states. We derive a family of Bell inequalities which require three measurement settings for each party and are maximally violated by graph states. In turn, any graph state violates at least one of the inequalities. We show that for certain types of graph states the violation of these inequalities increases exponentially with the number of qubits. We also discuss connections to other entanglement properties such as the positively of the partial transpose or the geometric measure of entanglement. (author)

Network reconstruction via graph blending
Estrada, Rolando
2016-05-01
Graphs estimated from empirical data are often noisy and incomplete due to the difficulty of faithfully observing all the components (nodes and edges) of the true graph. This problem is particularly acute for large networks where the number of components may far exceed available surveillance capabilities. Errors in the observed graph can render subsequent analyses invalid, so it is vital to develop robust methods that can minimize these observational errors. Errors in the observed graph may include missing and spurious components, as well fused (multiple nodes are merged into one) and split (a single node is misinterpreted as many) nodes. Traditional graph reconstruction methods are only able to identify missing or spurious components (primarily edges, and to a lesser degree nodes), so we developed a novel graph blending framework that allows us to cast the full estimation problem as a simple edge addition/deletion problem. Armed with this framework, we systematically investigate the viability of various topological graph features, such as the degree distribution or the clustering coefficients, and existing graph reconstruction methods for tackling the full estimation problem. Our experimental results suggest that incorporating any topological feature as a source of information actually hinders reconstruction accuracy. We provide a theoretical analysis of this phenomenon and suggest several avenues for improving this estimation problem.

To assess the prevalence of body dysmorphic disorder (BDD) in an aesthetic surgery setting in the region of Southwest China, and to ascertain the differences in terms of body images between patients in the aesthetic setting and general Chinese population. This study tracked patient satisfaction with their body image changes while undergoing aesthetic medical procedures to identify whether the condition of patients who were presenting with BDD symptoms or their psychological symptoms could be improved by enhancing their appearance. Additionally, this study explored whether there was improvement in quality of life (QoL) and self-esteem after aesthetic medical procedures. A total of 106 female patients who were undergoing aesthetic medical procedures for the first time (plastic surgery, n = 26; minimally invasive aesthetic treatment, n = 42; and aesthetic dermatological treatment, n = 38) were classified as having body dysmorphic disorder symptoms or not having body dysmorphic disorder symptoms, based on the body dysmorphic disorder examination (BDDE), which was administered preoperatively. These patients were followed up for 1 month after the aesthetic procedures. The multidimensional body self-relations questionnaire-appearance scales (MBSRQ-AS) and rosenberg self-esteem scale (RSE-S) were used to assess patients' preoccupation with appearance and self-esteem pre-procedure and 1 month post-procedure. Additionally, 100 female healthy control participants were recruited as a comparative group into this study and they were also assessed using BDDE, MBSRQ-AS, and RSE-S. A total of 14.2 % of 106 aesthetic patients and 1 % of 100 healthy controls were diagnosed with BDD to varying extents. BDDE scores were 72.83 (SD ± 30.7) and 68.18 (SD ± 31.82), respectively, before and after the procedure for the aesthetic patient group and 43.44 (SD ± 15.65) for the healthy control group (F = 34.28; p aesthetic patients (pre-procedure) and female adult norms from
Quantum chaos on discrete graphs

Adapting a method developed for the study of quantum chaos on quantum (metric) graphs (Kottos and Smilansky 1997 Phys. Rev. Lett. 79 4794, Kottos and Smilansky 1999 Ann. Phys., NY 274 76), spectral ζ functions and trace formulae for discrete Laplacians on graphs are derived. This is achieved by expressing the spectral secular equation in terms of the periodic orbits of the graph and obtaining functions which belong to the class of ζ functions proposed originally by Ihara (1966 J. Mat. Soc. Japan 18 219) and expanded by subsequent authors (Stark and Terras 1996 Adv. Math. 121 124, Kotani and Sunada 2000 J. Math. Sci. Univ. Tokyo 7 7). Finally, a model of 'classical dynamics' on the discrete graph is proposed. It is analogous to the corresponding classical dynamics derived for quantum graphs (Kottos and Smilansky 1997 Phys. Rev. Lett. 79 4794, Kottos and Smilansky 1999 Ann. Phys., NY 274 76). (fast track communication)
RJSplot: Interactive Graphs with R.
Barrios, David; Prieto, Carlos
2018-03-01
Data visualization techniques provide new methods for the generation of interactive graphs. These graphs allow a better exploration and interpretation of data but their creation requires advanced knowledge of graphical libraries. Recent packages have enabled the integration of interactive graphs in R. However, R provides limited graphical packages that allow the generation of interactive graphs for computational biology applications. The present project has joined the analytical power of R with the interactive graphical features of JavaScript in a new R package (RJSplot). It enables the easy generation of interactive graphs in R, provides new visualization capabilities, and contributes to the advance of computational biology analytical methods. At present, 16 interactive graphics are available in RJSplot, such as the genome viewer, Manhattan plots, 3D plots, heatmaps, dendrograms, networks, and so on. The RJSplot package is freely available online at http://rjsplot.net. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

On characterizing terrain visibility graphs
Directory of Open Access Journals (Sweden)
William Evans
2015-06-01
Full Text Available A terrain is an $x$-monotone polygonal line in the $xy$-plane. Two vertices of a terrain are mutually visible if and only if there is no terrain vertex on or above the open line segment connecting them. A graph whose vertices represent terrain vertices and whose edges represent mutually visible pairs of terrain vertices is called a terrain visibility graph. We would like to find properties that are both necessary and sufficient for a graph to be a terrain visibility graph; that is, we would like to characterize terrain visibility graphs.Abello et al. [Discrete and Computational Geometry, 14(3:331--358, 1995] showed that all terrain visibility graphs are “persistent”. They showed that the visibility information of a terrain point set implies some ordering requirements on the slopes of the lines connecting pairs of points in any realization, and as a step towards showing sufficiency, they proved that for any persistent graph $M$ there is a total order on the slopes of the (pseudo lines in a generalized configuration of points whose visibility graph is $M$.We give a much simpler proof of this result by establishing an orientation to every triple of vertices, reflecting some slope ordering requirements that are consistent with $M$ being the visibility graph, and prove that these requirements form a partial order. We give a faster algorithm to construct a total order on the slopes. Our approach attempts to clarify the implications of the graph theoretic properties on the ordering of the slopes, and may be interpreted as defining properties on an underlying oriented matroid that we show is a restricted type of $3$-signotope.

Graph embedding with rich information through heterogeneous graph
Sun, Guolei
2017-11-12
Graph embedding, aiming to learn low-dimensional representations for nodes in graphs, has attracted increasing attention due to its critical application including node classification, link prediction and clustering in social network analysis. Most existing algorithms for graph embedding only rely on the topology information and fail to use the copious information in nodes as well as edges. As a result, their performance for many tasks may not be satisfactory. In this thesis, we proposed a novel and general framework for graph embedding with rich text information (GERI) through constructing a heterogeneous network, in which we integrate node and edge content information with graph topology. Specially, we designed a novel biased random walk to explore the constructed heterogeneous network with the notion of flexible neighborhood. Our sampling strategy can compromise between BFS and DFS local search on heterogeneous graph. To further improve our algorithm, we proposed semi-supervised GERI (SGERI), which learns graph embedding in an discriminative manner through heterogeneous network with label information. The efficacy of our method is demonstrated by extensive comparison experiments with 9 baselines over multi-label and multi-class classification on various datasets including Citeseer, Cora, DBLP and Wiki. It shows that GERI improves the Micro-F1 and Macro-F1 of node classification up to 10%, and SGERI improves GERI by 5% in Wiki.

through the meeting with form. Therefore, since form has been the major theme for the aesthetics up until now, giving form to light is a complex and challenging task and reducing it to Lux and measurable numbers only an escape from facing what is actually percieved. In this way light seems to suffer from...... this article tries to establish a dialogue between the daylight and the artificial lighting. The article describes how light - this intangible building block – can become a more workable size in the aesthetic and architectural practice of today.

A linear graph for digoxin radioimmunoassay
International Nuclear Information System (INIS)
Smith, S.E.; Richter, A.
1975-01-01
The determination of drug or hormone concentrations by radio-immunoassay involves interpolation of values for radioisotope counts within standard curves, a technique which requires some dexterity in curve drawing and which results in some inaccuracy in practice. Most of the procedures designed to overcome these difficulties are complex and time-consuming. In radioimmunoassays involving saturation of the antibody-binding sites a special case exists in that the bound radioactivity is directly proportional to the specific activity of the ligand in the system. Thus a graph of the ratio of radioactivity bound in the absence to that in the presence of added non-radioactive ligand is linear against the concentration of added ligand (Hales,C.N., and Randle, P.J., 1963, Biochem. J., vol. 88, 137). A description is given of a simple and convenient modification of their method, and its application to the routine clinical determination of digoxin using a commercial kit (Lanoxitest β digoxin radioimmunoassay kit, Wellcome Reagents Ltd.). Specially constructed graph paper, which yields linearity with standard solutions, was designed so that it could be used directly without data transmission. The specific activity function appears as the upper arithmetical horizontal scale; corresponding values of the concentration of non-radioactive ligand in the solution added were individually calculated and appear on the lower scale opposite the appropriate values of the upper scale. The linearity of the graphs obtained confirmed that binding of digoxin was approximately constant through the range of clinical concentrations tested (0.5 to 8ng/ml), although binding declined slightly at higher concentrations.

Aesthetic chills: Knowledge-acquisition, meaning-making and aesthetic emotions

2016-08-01
Full Text Available This article addresses the relation between aesthetic emotions, knowledge-acquisition, and meaning-making. We briefly review theoretical foundations and present experimental data related to aesthetic chills. These results suggest that aesthetic chills are inhibited by exposing the subject to an incoherent prime prior to the chill-eliciting stimulation, and that a meaningful prime makes the aesthetic experience more pleasurable than a neutral or an incoherent one. Aesthetic chills induced by narrative structures seem to be related to the pinnacle of the story, to have a significant calming effect and subjects describe a strong empathy for the characters. We discuss the relation between meaning-making and aesthetic emotions at the psychological, physiological, narratological, and mathematical levels and propose a series of hypotheses to be tested in future research.
Brain and Aesthetic Attitude: How to Integrate "Old" and "New" Aesthetics
Directory of Open Access Journals (Sweden)
Gianluca Consoli
2014-01-01
Full Text Available At present, various efforts are being put forward to naturalize aesthetics. One of the most controversial disciplines of aesthetics is neuroaesthetics. The first applications of neuroimaging of the aesthetic experience of paintings occurred ten years ago. Over this decade, neuroscientific findings have determined three common centers of visual aesthetic experience: top-down processing; reward and evaluation; and cortical sensory processing. Undoubtedly, these common centers require better identification and further investigation. However, the experimental data currently available make it possible to falsify or corroborate traditional philosophical theories of aesthetic perception and evaluation. Within an integrated approach to aesthetics, this selective function might constitute a future role for neuroaesthetics in humanities research.
Interest in Aesthetic Rhinoplasty Scale.
Naraghi, Mohsen; Atari, Mohammad
2017-04-01
Interest in cosmetic surgery is increasing, with rhinoplasty being one of the most popular surgical procedures. It is essential that surgeons identify patients with existing psychological conditions before any procedure. This study aimed to develop and validate the Interest in Aesthetic Rhinoplasty Scale (IARS). Four studies were conducted to develop the IARS and to evaluate different indices of validity (face, content, construct, criterion, and concurrent validities) and reliability (internal consistency, split-half coefficient, and temporal stability) of the scale. The four study samples included a total of 463 participants. Statistical analysis revealed satisfactory psychometric properties in all samples. Scores on the IARS were negatively correlated with self-esteem scores ( r = -0.296; p social dysfunction ( r = 0.268; p < 0.01), and depression ( r = 0.308; p < 0.01). The internal and test-retest coefficients of consistency were found to be high (α = 0.93; intraclass coefficient = 0.94). Rhinoplasty patients were found to have significantly higher IARS scores than nonpatients ( p < 0.001). Findings of the present studies provided evidence for face, content, construct, criterion, and concurrent validities and internal and test-retest reliability of the IARS. This evidence supports the use of the scale in clinical and research settings. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.
Stolen beauty: gender, aesthetics and embodiment in Brazilian drama
Directory of Open Access Journals (Sweden)
Heloisa Pontes
2008-01-01
Full Text Available Drawing from a broader research on gender inflections in the Brazilian intellectual field and in Brazilian drama, between 1940 and 1968, the article discusses the relations between aesthetics and gender, and their implications on the careers of actresses Cacilda Becker, Maria Della Costa, Tônia Carrero and Cleyde Yáconis. According to testimony of those who saw her perform on stage, Cacilda was never hampered by her less favorable physical attributes. The hypothesis is that this is due to the cunning tricks of the conventions of dramatic arts that allow the dodging of social, gender and physical constraints. Widely evoked by the media to portrait, underline or diminish women under its focus, beauty rarely features as a relevant dimension in the analysis of female trajectories. Hence the interest in discussing the subject through its refraction on the process of social construction of artistic careers.
Hierarchy of modular graph identities
International Nuclear Information System (INIS)
D’Hoker, Eric; Kaidi, Justin
2016-01-01
The low energy expansion of Type II superstring amplitudes at genus one is organized in terms of modular graph functions associated with Feynman graphs of a conformal scalar field on the torus. In earlier work, surprising identities between two-loop graphs at all weights, and between higher-loop graphs of weights four and five were constructed. In the present paper, these results are generalized in two complementary directions. First, all identities at weight six and all dihedral identities at weight seven are obtained and proven. Whenever the Laurent polynomial at the cusp is available, the form of these identities confirms the pattern by which the vanishing of the Laurent polynomial governs the full modular identity. Second, the family of modular graph functions is extended to include all graphs with derivative couplings and worldsheet fermions. These extended families of modular graph functions are shown to obey a hierarchy of inhomogeneous Laplace eigenvalue equations. The eigenvalues are calculated analytically for the simplest infinite sub-families and obtained by Maple for successively more complicated sub-families. The spectrum is shown to consist solely of eigenvalues s(s−1) for positive integers s bounded by the weight, with multiplicities which exhibit rich representation-theoretic patterns.
Semantic graphs and associative memories
Pomi, Andrés; Mizraji, Eduardo
2004-12-01
Graphs have been increasingly utilized in the characterization of complex networks from diverse origins, including different kinds of semantic networks. Human memories are associative and are known to support complex semantic nets; these nets are represented by graphs. However, it is not known how the brain can sustain these semantic graphs. The vision of cognitive brain activities, shown by modern functional imaging techniques, assigns renewed value to classical distributed associative memory models. Here we show that these neural network models, also known as correlation matrix memories, naturally support a graph representation of the stored semantic structure. We demonstrate that the adjacency matrix of this graph of associations is just the memory coded with the standard basis of the concept vector space, and that the spectrum of the graph is a code invariant of the memory. As long as the assumptions of the model remain valid this result provides a practical method to predict and modify the evolution of the cognitive dynamics. Also, it could provide us with a way to comprehend how individual brains that map the external reality, almost surely with different particular vector representations, are nevertheless able to communicate and share a common knowledge of the world. We finish presenting adaptive association graphs, an extension of the model that makes use of the tensor product, which provides a solution to the known problem of branching in semantic nets.

Animated construction of line drawings
Fu, Hongbo
2011-12-01
Revealing the sketching sequence of a line drawing can be visually intriguing and used for video-based storytelling. Typically this is enabled based on tedious recording of artists\\' drawing process. We demonstrate that it is often possible to estimate a reasonable drawing order from a static line drawing with clearly defined shape geometry, which looks plausible to a human viewer. We map the key principles of drawing order from drawing cognition to computational procedures in our framework. Our system produces plausible animated constructions of input line drawings, with no or little user intervention. We test our algorithm on a range of input sketches, with varying degree of complexity and structure, and evaluate the results via a user study. We also present applications to gesture drawing synthesis and drawing animation creation especially in the context of video scribing.

The Evolutionary Value of an Aesthetic Sense

Stephen Davies
2013-12-01
Full Text Available The aesthetic sense we inherited from our successful ancestors drew them toward conditions that made for survival and reproductive success and repelled them away from conditions that impacted negatively on longevity and fertility. But for them, as for us, those desirable outcomes were incidental and uncalculated. Their search was for the beautiful and sublime. Aesthetic behaviours are apparent in our forerunner species about 400,000 years ago. They sometimes made symmetrical hand axes that were then not used. We can take an aesthetic interest in more or less anything, but the aesthetic responses that are rooted in our biology include those to landscapes and environments, to non-human animals, and to the appearance and behaviour of our fellow humans.

Aesthetic Diagnosis in Gestalt Therapy †
Roubal, Jan; Francesetti, Gianni; Gecele, Michela
2017-01-01
The diagnostic process in psychotherapy using the aesthetic evaluation is described in this article. Unlike the classical diagnostic process, which presents a result of comparing clinicians´ observations with a diagnostic system (DSM, ICD, etc.), the aesthetic evaluation is a pre-reflexive, embodied, and preverbal process. A Gestalt Therapy theoretical frame is used to introduce a concept of the aesthetic diagnostic process. During this process, the clinicians use their own here-and-now presence, which takes part in the co-creation of the shared relational field during the therapeutic session. A specific procedure of the aesthetic evaluation is introduced. The clinical work with depressed clients is presented to illustrate this perspective. PMID:29039752
The phenomenology in the environmental aesthetic education

2000-01-01
In this paper we present an abstract about our Philosophical Doctor Thesis make on Campinas University (Sao Paulo, Brazil) titled educacion estetico ambiental y fenomenologia: problemas de la educacion estetico ambiental en la modernidad. In this thesis we do a critical thinking about the epistemological model of relation subject -object on modern education, and on the other side, we work in the construction about a aesthetic - environmental education model. We propose here an aesthetization of the education, for conjoint body and world-of-life (lebenswelt) into scenarios and actors of the pedagogical process. Body and world-of-life, are two concepts of Husserl's phenomenology that open the door about the environment' s studies aesthetization and aesthetic' s studies environment, separated on modernity, between the metaphysical subject and physicality objects. Body and world-of-life -symbolic-biotic- are marginal alterities on modernity. This marginality has been a structural lead on the contemporary environmental problems
Trash and Aesthetics in the Hoard
Directory of Open Access Journals (Sweden)
Charmaine Eddy
2015-06-01
Full Text Available Trash and Aesthetics in the Hoard by Charmaine Eddy, Issue 7: The Aesthetics of Trash. This article examines two reality television series, Hoarders and Hoarding: Buried Alive, in terms of a variation in the understanding of the object in relation to value based upon an aesthetic tied to consumer capitalism. Object collection is viewed as a spectacle of abjection in each episode, as items that were once worthy of purchase come to produce a garbage heap within the home. The concept of “trash” is an evaluative category applied to objects over time, but it also becomes part of the therapeutic process, as hoarders are required to dispose of their things. Object-oriented ontology, or “thing theory,” provides an alternate semiology for the object, ultimately illustrating how an evaluative aesthetics of the object in these series is linked to consumer capitalism and normative patterns of consumption.
Cultural history and aesthetics of nursing care.
Siles González, José; Ruiz, Maria del Carmen Solano
2011-01-01
The aim of this study was to clarify the role of aesthetics in the organization and motivation of care through history. The guiding questions were: What values and aesthetic feelings have supported and motivated pre-professional and professional care? and Based on what structures has pre-professional and professional care been historically socialized? Primary and secondary sources were consulted, selected according to established criteria with a view to avoiding search and selection bias. Data analysis was guided by the categories: "habitus" and "logical conformism". It was found that the relation between social structures and pre-professionals (motherhood, religiosity) and professional aesthetic standards (professionalism, technologism) of care through history is evidenced in the caregiving activity of the functional unit, in the functional framework and the functional element. In conclusion, in social structures, through the socialization process, "logical conformism" and "habitus" constitute the aesthetic standards of care through feelings like motherhood, religiosity, professionalism, technologism and humanism.

2011-08-01
Appearance of the male genitalia is linked with self-esteem and sexual identity. Aesthetic surgery of the male genitalia serves to correct perceived deficiencies as well as physical deformities, which may cause psychological distress. Attention to patient motivation for surgery and to surgical technique is key to achieving optimal results. In this review, the authors describe aesthetic surgical techniques for treatment of penile and scrotal deficiencies. They also discuss techniques for revision in patients with previous surgery.

d-spheres in graph theory are inductively defined as graphs for which all unit spheres S(x) are (d-1)-spheres and that the removal of one vertex renders the graph contractible. Eulerian d-spheres are geometric d-spheres which are d+1 colorable. We prove here that G is an Eulerian sphere if and only if the degrees of all the (d-2)-dimensional sub-simplices in G are even. This generalizes a Kempe-Heawood result for d=2 and is work related to the conjecture that all d-spheres have chromatic numb...

Orthodontics in the "Art" of Aesthetics.
Thomas, Mayuri
2015-01-01
Aesthetics in dentistry has of late become an awakening/actor among patients and often serves as a major reason for seeking dental treatment and care. Ever since the introduction of orthodontics as a separate specialty branch in dentistry, a variety of techniques have evolved, and methods developed both in the type of devices/instruments used and treatments planned. The discipline of orthodontic aesthetics involves micro and macro aesthetics, gingival, and facial aesthetics. This article helps focus on the artistic part of the orthodontic science. It brings out various important factors involved in customizing aesthetic orthodontic treatment planning according to the individual needs of the patient. Through this kind of treatment planning not only are the functional and biological needs of the patient met, they also provide a stable and durable results. Less invasive treatment planning makes it easier for the patient to select future treatment options as new technologies keep evolving. The review was selected by typing aesthetic orthodontics in the Google search engine, Pubmed, and Pubmed Central. Literature review of articles reflecting history, different analysis, factors responsible, and the latest technique was conducted.
Reshaping Spectatorship: Immersive and Distributed Aesthetics

Edwina Bartlem
2005-01-01
Full Text Available Although discourses of immersive aesthetics and distributed aesthetics may evoke associations with different media, creative processes, modes of audience engagement and even political ideologies, artists using these aesthetics often share similar interests in transforming and enhancing notions of the body and perception through technological intervention. This paper undertakes a comparison between immersive and distributed aesthetics in relation to Virtual Reality (VR and Networked Art (net.art, particularly networked installation art. It focuses on the ways in which both VR and networked installations immerse the viewer in states of perceptual and cognitive transition. Central to this article is the argument that VR and net.art are able to generate immersive experiences in the viewer by creating the sensation of being (tele-present in an electronically mediated environment that is illusionistic and sometimes remote from the physical body of the participant. Furthermore, the immersive and distributed aesthetics generated by specific VR and net.art projects have revolutionary consequences for traditional aesthetic theories of spectatorship and art appreciation that assert the need for critical and physical distance.
Brain correlates of aesthetic judgment of beauty.
Jacobsen, Thomas; Schubotz, Ricarda I; Höfel, Lea; Cramon, D Yves V
2006-01-01
Functional MRI was used to investigate the neural correlates of aesthetic judgments of beauty of geometrical shapes. Participants performed evaluative aesthetic judgments (beautiful or not?) and descriptive symmetry judgments (symmetric or not?) on the same stimulus material. Symmetry was employed because aesthetic judgments are known to be often guided by criteria of symmetry. Novel, abstract graphic patterns were presented to minimize influences of attitudes or memory-related processes and to test effects of stimulus symmetry and complexity. Behavioral results confirmed the influence of stimulus symmetry and complexity on aesthetic judgments. Direct contrasts showed specific activations for aesthetic judgments in the frontomedian cortex (BA 9/10), bilateral prefrontal BA 45/47, and posterior cingulate, left temporal pole, and the temporoparietal junction. In contrast, symmetry judgments elicited specific activations in parietal and premotor areas subserving spatial processing. Interestingly, beautiful judgments enhanced BOLD signals not only in the frontomedian cortex, but also in the left intraparietal sulcus of the symmetry network. Moreover, stimulus complexity caused differential effects for each of the two judgment types. Findings indicate aesthetic judgments of beauty to rely on a network partially overlapping with that underlying evaluative judgments on social and moral cues and substantiate the significance of symmetry and complexity for our judgment of beauty.

Game theory is one of the key paradigms behind many scientific disciplines from biology to behavioral sciences to economics. In its evolutionary form and especially when the interacting agents are linked in a specific social network the underlying solution concepts and methods are very similar to those applied in non-equilibrium statistical physics. This review gives a tutorial-type overview of the field for physicists. The first four sections introduce the necessary background in classical and evolutionary game theory from the basic definitions to the most important results. The fifth section surveys the topological complications implied by non-mean-field-type social network structures in general. The next three sections discuss in detail the dynamic behavior of three prominent classes of models: the Prisoner's Dilemma, the Rock-Scissors-Paper game, and Competing Associations. The major theme of the review is in what sense and how the graph structure of interactions can modify and enrich the picture of long term behavioral patterns emerging in evolutionary games.
Drawing evaluation report for sampling equipment drawings; TOPICAL

This document presents the results of a task to evaluate Tank Waste Remediation System (TWRS) sampling equipment drawings and identifies drawings category as either essential, support, or general drawings. This report completes the drawing evaluation task as outlined in Engineering Task Plan For Truck 3 and 4 Drawing Compliance and Evaluation (Wilson, 1997). The scope of this report is limited to an evaluation and identification of drawing category for drawings of certain tank waste sampling equipment for which the TRWS Characterization Project has been assigned custody, including: vapor sampling, grab sampling, auger sampling, and all core sampling equipment (see LMHC Task Order 304). This report does not address drawings for other waste tank deployed equipment systems having similar assigned custody, such as, Light Duty Utility Arm (LDUA), Cone Penetrometer system, or Long Length Contaminated Equipment (LLCE). The LDUA drawings are addressed in the Characterization Equipment Essential Drawings (HNF 1998). The Cone Penetrometer system drawings which are vendor drawings (not H- series) is not currently turned over to operations for deployment. The LLCE equipment was just recently assigned to Characterization Project and were not included in the original scope for this evaluation and will be addressed in the evaluation update scheduled for fiscal year 1999
Drawing experts have better visual memory while drawing.
Perdreau, Florian; Cavanagh, Patrick
2015-01-01
Drawing involves frequent shifts of gaze between the original and the drawing and visual memory helps compare the original object and the drawing across these gaze shifts while creating and correcting the drawing. It remains unclear whether this memory encodes all of the object or only the features around the current drawing position and whether both the original and the copy are equally well represented. To address these questions, we designed a "drawing" experiment coupled with a change detection task. A polygon was displayed on one screen and participants had to copy it on another, with the original and the drawing presented in alternation. At unpredictable moments during the copying process, modifications were made on the drawing and the original figure (while they were not in view). Participants had to correct their drawing every time they perceived a change so that their drawing always matched the current original figure. Our results show a better memory representation of the original figure than of the drawing, with locations relevant to the current production most accurately represented. Critically, experts showed better memory for both the original and the drawing than did novices, suggesting that experts have specialized advantages for encoding visual shapes.
Image-guided automatic triggering of a fractional CO2 laser in aesthetic procedures.
Wilczyński, Sławomir; Koprowski, Robert; Wiernek, Barbara K; Błońska-Fajfrowska, Barbara
2016-09-01
Laser procedures in dermatology and aesthetic medicine are associated with the need for manual laser triggering. This leads to pulse overlapping and side effects. Automatic laser triggering based on image analysis can provide a secure fit to each successive doses of radiation. A fractional CO2 laser was used in the study. 500 images of the human skin of healthy subjects were acquired. Automatic triggering was initiated by an application together with a camera which tracks and analyses the skin in visible light. The tracking algorithm uses the methods of image analysis to overlap images. After locating the characteristic points in analysed adjacent areas, the correspondence of graphs is found. The point coordinates derived from the images are the vertices of graphs with respect to which isomorphism is sought. When the correspondence of graphs is found, it is possible to overlap the neighbouring parts of the image. The proposed method of laser triggering owing to the automatic image fitting method allows for 100% repeatability. To meet this requirement, there must be at least 13 graph vertices obtained from the image. For this number of vertices, the time of analysis of a single image is less than 0.5s. The proposed method, applied in practice, may help reduce the number of side effects during dermatological laser procedures resulting from laser pulse overlapping. In addition, it reduces treatment time and enables to propose new techniques of treatment through controlled, precise laser pulse overlapping. Copyright © 2016 Elsevier Ltd. All rights reserved.

2018-01-01
A comprehensive survey of proper connection of graphs is discussed in this book with real world applications in computer science and network security. Beginning with a brief introduction, comprising relevant definitions and preliminary results, this book moves on to consider a variety of properties of graphs that imply bounds on the proper connection number. Detailed proofs of significant advancements toward open problems and conjectures are presented with complete references. Researchers and graduate students with an interest in graph connectivity and colorings will find this book useful as it builds upon fundamental definitions towards modern innovations, strategies, and techniques. The detailed presentation lends to use as an introduction to proper connection of graphs for new and advanced researchers, a solid book for a graduate level topics course, or as a reference for those interested in expanding and further developing research in the area.

Enterprises monitor cyber traffic for viruses, intruders and stolen information. Detection methods look for known signatures of malicious traffic or search for anomalies with respect to a nominal reference model. Traditional anomaly detection focuses on aggregate traffic at central nodes or on user-level monitoring. More recently, however, traffic is being viewed more holistically as a dynamic communication graph. Attention to the graph nature of the traffic has expanded the types of anomalies that are being sought. We give an overview of several cyber data streams collected at Los Alamos National Laboratory and discuss current work in modeling the graph dynamics of traffic over the network. We consider global properties and local properties within the communication graph. A method for monitoring relative entropy on multiple correlated properties is discussed in detail.
Open Graphs and Computational Reasoning
Directory of Open Access Journals (Sweden)
Lucas Dixon
2010-06-01
Full Text Available We present a form of algebraic reasoning for computational objects which are expressed as graphs. Edges describe the flow of data between primitive operations which are represented by vertices. These graphs have an interface made of half-edges (edges which are drawn with an unconnected end and enjoy rich compositional principles by connecting graphs along these half-edges. In particular, this allows equations and rewrite rules to be specified between graphs. Particular computational models can then be encoded as an axiomatic set of such rules. Further rules can be derived graphically and rewriting can be used to simulate the dynamics of a computational system, e.g. evaluating a program on an input. Examples of models which can be formalised in this way include traditional electronic circuits as well as recent categorical accounts of quantum information.

In this short note we argue that the toughness of split graphs can be computed in polynomial time. This solves an open problem from a recent paper by Kratsch et al. (Discrete Math. 150 (1996) 231–245).
Generating random networks and graphs
Coolen, Ton; Roberts, Ekaterina
2017-01-01
This book supports researchers who need to generate random networks, or who are interested in the theoretical study of random graphs. The coverage includes exponential random graphs (where the targeted probability of each network appearing in the ensemble is specified), growth algorithms (i.e. preferential attachment and the stub-joining configuration model), special constructions (e.g. geometric graphs and Watts Strogatz models) and graphs on structured spaces (e.g. multiplex networks). The presentation aims to be a complete starting point, including details of both theory and implementation, as well as discussions of the main strengths and weaknesses of each approach. It includes extensive references for readers wishing to go further. The material is carefully structured to be accessible to researchers from all disciplines while also containing rigorous mathematical analysis (largely based on the techniques of statistical mechanics) to support those wishing to further develop or implement the theory of rand...

The problem of identifying a functor between the categories of algebras and graphs is currently open. Based on a known algorithm that identifies isomorphisms of Latin squares with isomorphism of vertex-colored graphs, we describe here a pair of graphs that enable us to find a faithful functor between finite-dimensional algebras over finite fields and these graphs.

The spectra of the skew-adjacency matrices of a graph are considered as a possible way to distinguish adjacency cospectral graphs. This leads to the following topics: graphs whose skew-adjacency matrices are all cospectral; relations between the matchings polynomial of a graph and the characteristic
Chromatic polynomials of random graphs

2010-01-01
Chromatic polynomials and related graph invariants are central objects in both graph theory and statistical physics. Computational difficulties, however, have so far restricted studies of such polynomials to graphs that were either very small, very sparse or highly structured. Recent algorithmic advances (Timme et al 2009 New J. Phys. 11 023001) now make it possible to compute chromatic polynomials for moderately sized graphs of arbitrary structure and number of edges. Here we present chromatic polynomials of ensembles of random graphs with up to 30 vertices, over the entire range of edge density. We specifically focus on the locations of the zeros of the polynomial in the complex plane. The results indicate that the chromatic zeros of random graphs have a very consistent layout. In particular, the crossing point, the point at which the chromatic zeros with non-zero imaginary part approach the real axis, scales linearly with the average degree over most of the density range. While the scaling laws obtained are purely empirical, if they continue to hold in general there are significant implications: the crossing points of chromatic zeros in the thermodynamic limit separate systems with zero ground state entropy from systems with positive ground state entropy, the latter an exception to the third law of thermodynamics.
Commuting graphs of matrix algebras

Akbari, S.; Bidkhori, H.; Mohammadian, A.
2006-08-01
The commuting graph of a ring R, denoted by Γ(R), is a graph whose vertices are all non- central elements of R and two distinct vertices x and y are adjacent if and only if xy = yx. The commuting graph of a group G, denoted by Γ(G), is similarly defined. In this paper we investigate some graph theoretic properties of Γ(M n (F)), where F is a field and n ≥ 2. Also we study the commuting graphs of some classical groups such as GL n (F) and SL n (F). We show that Γ(M n (F)) is a connected graph if and only if every field extension of F of degree n contains a proper intermediate field. We prove that apart from finitely many fields, a similar result is true for Γ(GL n (F)) and Γ(SL n (F)). Also we show that for two fields E and F and integers m, n ≥> 2, if Γ(M m (E)) ≅ Γ(M n (F)), then m = n and vertical bar E vertical bar = vertical bar F vertical bar. (author)

Using Behavior Over Time Graphs to Spur Systems Thinking Among Public Health Practitioners.
Calancie, Larissa; Anderson, Seri; Branscomb, Jane; Apostolico, Alexsandra A; Lich, Kristen Hassmiller
2018-02-01
Public health practitioners can use Behavior Over Time (BOT) graphs to spur discussion and systems thinking around complex challenges. Multiple large systems, such as health care, the economy, and education, affect chronic disease rates in the United States. System thinking tools can build public health practitioners' capacity to understand these systems and collaborate within and across sectors to improve population health. BOT graphs show a variable, or variables (y axis) over time (x axis). Although analyzing trends is not new to public health, drawing BOT graphs, annotating the events and systemic forces that are likely to influence the depicted trends, and then discussing the graphs in a diverse group provides an opportunity for public health practitioners to hear each other's perspectives and creates a more holistic understanding of the key factors that contribute to a trend. We describe how BOT graphs are used in public health, how they can be used to generate group discussion, and how this process can advance systems-level thinking. Then we describe how BOT graphs were used with groups of maternal and child health (MCH) practitioners and partners (N = 101) during a training session to advance their thinking about MCH challenges. Eighty-six percent of the 84 participants who completed an evaluation agreed or strongly agreed that they would use this BOT graph process to engage stakeholders in their home states and jurisdictions. The BOT graph process we describe can be applied to a variety of public health issues and used by practitioners, stakeholders, and researchers.
Graph Quasicontinuous Functions and Densely Continuous Forms

Full Text Available Let $X, Y$ be topological spaces. A function $f: X \\to Y$ is said to be graph quasicontinuous if there is a quasicontinuous function $g: X \\to Y$ with the graph of $g$ contained in the closure of the graph of $f$. There is a close relation between the notions of graph quasicontinuous functions and minimal usco maps as well as the notions of graph quasicontinuous functions and densely continuous forms. Every function with values in a compact Hausdorff space is graph quasicontinuous; more generally every locally compact function is graph quasicontinuous.

Full Text Available Purpose: It has been known that psychological factors have an important effect on the decision to undergo aesthetic surgery. In this study, we aimed to test the hypothesis that the personality traits of people admitted for aesthetic surgery differ from those of people who have never planned to undergo aesthetic surgery in their lives. Material and Methods: Forty-seven patients who were referred to the outpatient clinic of the Faculty of Medicine, Department of Plastic, Reconstructive, and Aesthetic Surgery, Kirikkale University to undergo aesthetic surgery were enrolled in the study. Forty-three subjects who neither underwent nor planned to undergo aesthetic surgery at any time in their lives were included in the study as a control group. Psychometric evaluation of the patients and the control group was conducted using the Turkish version of the Minnesota Multiphasic Personality Inventory (MMPI. Results: Taking 65 as a cut-off point, the ratio of patients who scored and #8805;65 on the hysteria subscale of the MMPI was found to be significantly higher in the sugery group than in the control group and the ratio on social introversion subscale was also higher in the patient group than in the control group, very closely approaching significance. Conclusion: It should be kept in mind that people who have personality traits that can be partially improved with psyachiatric treatment, such as social introverted, lonely, timid, shy, and hysterical and feel the need for validation by others, may be more often admitted for aesthetic surgery.

Full Text Available The aesthetic expression and its orders are important for steel structures forming. Steel structures are a compilation of structural elements, where its shapes have standard dimensions and pre-fabricated. As the steel construction systems not only aim to achieve the functional requirements for users, but must also have the symbolic aesthetics which provides visually and cognitive expression for viewers. In this sense the research interested in expressional aesthetics in these systems and highlights the importance of attention as structural items. Therefore the visual items which related with steel structures contain some of the most powerful forms of modern architecture, steel structures with a glass cladding, agility and accuracy in manufacture of structural elements as visual items, structural interest in the forms of spaces which have long span systems or in high buildings are different forms of expression and influence. So the research focuses on the study of those expressive patterns related with the steel construction properties, including the advantages of these systems at the level of strength and firmness, flexibility and economy as well as aesthetic and expression. Accordingly, the research problem concentrated on educational shortage in the study of the structural steel system aspects concerning constructional characteristic, expressive and aesthetic features, and how to deal with them as a language bearing the symbols and meanings which have clear structural style, because it the best ways to make those systems as communication means with users, by premise that the use of expressional symbol in steel construction increases the aesthetic value. Therefore the research aims to reveal the most structural and expressive patterns by analysis the expressional means and steel structural aesthetics.

Graph-links arise as the intersection graphs of turning chord diagrams of links. Speaking informally, graph-links provide a combinatorial description of links up to mutations. Many link invariants can be reformulated in the language of graph-links. Khovanov homology, a well-known and useful knot invariant, is defined for graph-links in this paper (in the case of the ground field of characteristic two). Bibliography: 14 titles.

Full Text Available After the success of GNSS (Global Navigational Satellite Systems and navigation services for public streets, indoor seems to be the next big development in navigational services, relying on RTLS – Real Time Locating Services (e.g. WIFI and allowing seamless navigation. In contrast to navigation and routing services on public streets, seamless navigation will cause an additional challenge: how to make routing data accessible to defined users or restrict access rights for defined areas or only to parts of the graph to a defined user group? The paper will present case studies and data from literature, where seamless and especially indoor navigation solutions are presented (hospitals, industrial complexes, building sites, but the problem of restricted access rights was only touched from a real world, but not a technical perspective. The analysis of case studies will show, that the objective of navigation and the different target groups for navigation solutions will demand well defined access rights and require solutions, how to make only parts of a graph to a user or application available to solve a navigational task. The paper will therefore introduce the concept of private graphs, which is defined as a graph for navigational purposes covering the street, road or floor network of an area behind a public street and suggest different approaches how to make graph data for navigational purposes available considering access rights and data protection, privacy and security issues as well.
Confidence, Visual Research, and the Aesthetic Function
Directory of Open Access Journals (Sweden)
Stan Ruecker
2007-05-01
Full Text Available The goal of this article is to identify and describe one of the primary purposes of aesthetic quality in the design of computer interfaces and visualization tools. We suggest that humanists can derive advantages in visual research by acknowledging by their efforts to advance aesthetic quality that a significant function of aesthetics in this context is to inspire the user’s confidence. This confidence typically serves to create a sense of trust in the provider of the interface or tool. In turn, this increased trust may result in an increased willingness to engage with the object, on the basis that it demonstrates an attention to detail that promises to reward increased engagement. In addition to confidence, the aesthetic may also contribute to a heightened degree of satisfaction with having spent time using or investigating the object. In the realm of interface design and visualization research, we propose that these aesthetic functions have implications not only for the quality of interactions, but also for the results of the standard measures of performance and preference.
Aesthetic quality inference for online fashion shopping
Chen, Ming; Allebach, Jan
2014-03-01
On-line fashion communities in which participants post photos of personal fashion items for viewing and possible purchase by others are becoming increasingly popular. Generally, these photos are taken by individuals who have no training in photography with low-cost mobile phone cameras. It is desired that photos of the products have high aesthetic quality to improve the users' online shopping experience. In this work, we design features for aesthetic quality inference in the context of online fashion shopping. Psychophysical experiments are conducted to construct a database of the photos' aesthetic evaluation, specifically for photos from an online fashion shopping website. We then extract both generic low-level features and high-level image attributes to represent the aesthetic quality. Using a support vector machine framework, we train a predictor of the aesthetic quality rating based on the feature vector. Experimental results validate the efficacy of our approach. Metadata such as the product type are also used to further improve the result.
Towards a sensorimotor aesthetics of performing art.
Calvo-Merino, B; Jola, C; Glaser, D E; Haggard, P
2008-09-01
The field of neuroaesthetics attempts to identify the brain processes underlying aesthetic experience, including but not limited to beauty. Previous neuroaesthetic studies have focussed largely on paintings and music, while performing arts such as dance have been less studied. Nevertheless, increasing knowledge of the neural mechanisms that represent the bodies and actions of others, and which contribute to empathy, make a neuroaesthetics of dance timely. Here, we present the first neuroscientific study of aesthetic perception in the context of the performing arts. We investigated brain areas whose activity during passive viewing of dance stimuli was related to later, independent aesthetic evaluation of the same stimuli. Brain activity of six naïve male subjects was measured using fMRI, while they watched 24 dance movements, and performed an irrelevant task. In a later session, participants rated each movement along a set of established aesthetic dimensions. The ratings were used to identify brain regions that were more active when viewing moves that received high average ratings than moves that received low average ratings. This contrast revealed bilateral activity in the occipital cortices and in right premotor cortex. Our results suggest a possible role of visual and sensorimotor brain areas in an automatic aesthetic response to dance. This sensorimotor response may explain why dance is widely appreciated in so many human cultures.
Hospitalization and aesthetic health in older adults.
Moss, Hilary; Donnellan, Claire; O'Neill, Desmond
2015-02-01
To assess the impact of hospitalization on arts engagement among older people; and to assess perceptions of whether hospitals are aesthetically deprived environments. A Survey of Aesthetic and Cultural Health was developed to explore the role of aesthetics before, during and after hospital. Study participants were n = 150 hospital in-patients aged >65. Descriptive and inferential statistics were used to analyze the data. Attendance at arts events was an important part of life for this sample and a large drop off was noted in continuation of these activities in the year post-hospital stay. Physical health issues were the main causes but also loss of confidence and transport issues. Film, dance, and music were the most popular arts for this sample prior to hospital stay. Noise pollution caused by other patients, lack of control over TV/radio, and access to receptive arts in hospital (reading and listening to music) were important issues for patients in hospital. This study identifies a trend for decreasing exposure to arts beginning with a hospital stay and concludes that older people may need encouragement to resume engagement in arts following a hospital stay. There is relatively limited evidence regarding the nature of, and potential benefit from, aesthetics in healthcare and limited studies with rigorous methodology, and further research is needed to understand the aesthetic preferences of older people in hospital.

Aging well--the role of minimally invasive aesthetic dermatological procedures in women over 65.
Wollina, Uwe; Payne, Christopher Rowland
2010-03-01
The western world is getting older. Aging well has become the new target of preventative medicine. Aesthetic dermatology can contribute to this quest. Females over 65 represent an important and growing group of consumers of cosmetic procedures. In this group, there is a paucity of scientific evaluation of aesthetic procedures. To review the use of minimally invasive procedures for facial rejuvenation in women over 65. Drawing from both the literature and personal experience, the opportunities, modifications, and limitations of minimally invasive techniques for facial rejuvenation in older women are considered. In this older age group, dermal fillers, chemical and laser peels, and nonablative photorejuvenation remain useful and can each be used as stand-alone treatments. In this age group, botulinum toxin (BTX) injections are more often used in combination with other procedures. With respect to aesthetic procedures, women over 65 are different from younger women. More scientific investigation is necessary to better meet needs of this growing part of the population. Available data suggest that aesthetic dermatology can make a major contribution to the complex matter of aging well.
Should advertising by aesthetic surgeons be permitted?

2017-01-01
Full Text Available Cosmetic, aesthetic and cutaneous surgical procedures require qualified specialists trained in the various procedures and competent to handle complications. However, it also requires huge investments in terms of infrastructure, trained staff and equipment. To be viable advertising is essential to any establishment which provides cosmetic and aesthetic procedures. Business men with deep pockets establish beauty chains which also provide these services and advertise heavily to sway public opinion in their favour. However, these saloons and spas lack basic medical facilities in terms of staff or equipment to handle any complication or medical emergency. To have a level playing field ethical advertising should be permitted to qualified aesthetic surgeons as is permitted in the US and UK by their respective organisations.
Complications associated with cutaneous aesthetic procedures.
Hartmann, Daniela; Ruzicka, Thomas; Gauglitz, Gerd G
2015-08-01
In recent years, a plethora of novel therapeutic approaches to fight signs of aging and to influence external body appearance have become available in aesthetic dermatology. Extensive research in this field has led to advanced understanding of the anatomy and physiology of the aging face. To successfully address the complex age-related alterations anti-aging treatment nowadays calls for a multi-faceted approach. Most frequently utilized aesthetic procedures include the use of botulinum toxin, a variety of filling substances, microneedling (collagen induction therapy), chemical peeling, lasers, radiofrequency, thread facelift and injectional lipolysis with phosphatidylcholine/deoxycholate among others. Unfortunately, many clinicians still lack in-depth understanding of potential complications, risk factors and side effects associated with minimal-invasive procedures. The following review aims to give a broad overview of nowadays most frequently used approaches in the dermato-aesthetic field and their related complications. © 2015 Deutsche Dermatologische Gesellschaft (DDG).

Fractal Analysis of Stealthy Pathfinding Aesthetics
Directory of Open Access Journals (Sweden)
Ron Coleman
2009-01-01
Full Text Available This paper uses a fractal model to analyze aesthetic values of a new class of obstacle-prone or “stealthy” pathfinding which seeks to avoid detection, exposure, openness, and so forth in videogames. This study is important since in general the artificial intelligence literature has given relatively little attention to aesthetic outcomes in pathfinding. The data we report, according to the fractal model, suggests that stealthy paths are statistically significantly unique in relative aesthetic value when compared to control paths. We show furthermore that paths generated with different stealth regimes are also statistically significantly unique. These conclusions are supported by statistical analysis of model results on experimental trials involving pathfinding in randomly generated, multiroom virtual worlds.

Full Text Available Box graphs succinctly and comprehensively characterize singular fibers of elliptic fibrations in codimension two and three, as well as flop transitions connecting these, in terms of representation theoretic data. We develop a framework that provides a systematic map between a box graph and a crepant algebraic resolution of the singular elliptic fibration, thus allowing an explicit construction of the fibers from a singular Weierstrass or Tate model. The key tool is what we call a fiber face diagram, which shows the relevant information of a (partial toric triangulation and allows the inclusion of more general algebraic blowups. We shown that each such diagram defines a sequence of weighted algebraic blowups, thus providing a realization of the fiber defined by the box graph in terms of an explicit resolution. We show this correspondence explicitly for the case of SU(5 by providing a map between box graphs and fiber faces, and thereby a sequence of algebraic resolutions of the Tate model, which realizes each of the box graphs.

Degree-based graph construction is a ubiquitous problem in network modelling (Newman et al 2006 The Structure and Dynamics of Networks (Princeton Studies in Complexity) (Princeton, NJ: Princeton University Press), Boccaletti et al 2006 Phys. Rep. 424 175), ranging from social sciences to chemical compounds and biochemical reaction networks in the cell. This problem includes existence, enumeration, exhaustive construction and sampling questions with aspects that are still open today. Here we give necessary and sufficient conditions for a sequence of nonnegative integers to be realized as a simple graph's degree sequence, such that a given (but otherwise arbitrary) set of connections from an arbitrarily given node is avoided. We then use this result to present a swap-free algorithm that builds all simple graphs realizing a given degree sequence. In a wider context, we show that our result provides a greedy construction method to build all the f-factor subgraphs (Tutte 1952 Can. J. Math. 4 314) embedded within K n setmn S k , where K n is the complete graph and S k is a star graph centred on one of the nodes. (fast track communication)
Hierarchical organisation of causal graphs
International Nuclear Information System (INIS)
Dziopa, P.
1993-01-01
This paper deals with the design of a supervision system using a hierarchy of models formed by graphs, in which the variables are the nodes and the causal relations between the variables of the arcs. To obtain a representation of the variables evolutions which contains only the relevant features of their real evolutions, the causal relations are completed with qualitative transfer functions (QTFs) which produce roughly the behaviour of the classical transfer functions. Major improvements have been made in the building of the hierarchical organization. First, the basic variables of the uppermost level and the causal relations between them are chosen. The next graph is built by adding intermediary variables to the upper graph. When the undermost graph has been built, the transfer functions parameters corresponding to its causal relations are identified. The second task consists in the upwelling of the information from the undermost graph to the uppermost one. A fusion procedure of the causal relations has been designed to compute the QFTs relevant for each level. This procedure aims to reduce the number of parameters needed to represent an evolution at a high level of abstraction. These techniques have been applied to the hierarchical modelling of nuclear process. (authors). 8 refs., 12 figs
Integer Flows and Circuit Covers of Graphs and Signed Graphs
Cheng, Jian
The work in Chapter 2 is motivated by Tutte and Jaeger's pioneering work on converting modulo flows into integer-valued flows for ordinary graphs. For a signed graphs (G, sigma), we first prove that for each k ∈ {2, 3}, if (G, sigma) is (k - 1)-edge-connected and contains an even number of negative edges when k = 2, then every modulo k-flow of (G, sigma) can be converted into an integer-valued ( k + 1)-ow with a larger or the same support. We also prove that if (G, sigma) is odd-(2p+1)-edge-connected, then (G, sigma) admits a modulo circular (2 + 1/ p)-flows if and only if it admits an integer-valued circular (2 + 1/p)-flows, which improves all previous result by Xu and Zhang (DM2005), Schubert and Steffen (EJC2015), and Zhu (JCTB2015). Shortest circuit cover conjecture is one of the major open problems in graph theory. It states that every bridgeless graph G contains a set of circuits F such that each edge is contained in at least one member of F and the length of F is at most 7/5∥E(G)∥. This concept was recently generalized to signed graphs by Macajova et al. (JGT2015). In Chapter 3, we improve their upper bound from 11∥E( G)∥ to 14/3 ∥E(G)∥, and if G is 2-edgeconnected and has even negativeness, then it can be further reduced to 11/3 ∥E(G)∥. Tutte's 3-flow conjecture has been studied by many graph theorists in the last several decades. As a new approach to this conjecture, DeVos and Thomassen considered the vectors as ow values and found that there is a close relation between vector S1-flows and integer 3-NZFs. Motivated by their observation, in Chapter 4, we prove that if a graph G admits a vector S1-flow with rank at most two, then G admits an integer 3-NZF. The concept of even factors is highly related to the famous Four Color Theorem. We conclude this dissertation in Chapter 5 with an improvement of a recent result by Chen and Fan (JCTB2016) on the upperbound of even factors. We show that if a graph G contains an even factor, then it

Integrated color face graphs for plant accident display
International Nuclear Information System (INIS)
Hara, Fumio
1987-01-01
This paper presents an integrated man-machine interface that uses cartoon-like colored graphs in the form of faces, that, through different facial expressions, display a plant condition. This is done by drawing the face on a CRT by nonlinearly transforming 31 variables and coloring the face. This integrated color graphics technique is applied to display the progess of events in the Three Mile Island nuclear power plant accident. Human visual perceptive characteristics are investigated in relation to the perception of the plant accident process, the naturality in face color change, and the consistency between facial expressions and colors. This paper concludes that colors used in an integrated color face graphs must be completely consistent with emotional feelings perceived from the colors. (author)
A New Kind of Aesthetics —The Mathematical Structure of the Aesthetic
Directory of Open Access Journals (Sweden)
Akihiro Kubota
2017-06-01
Full Text Available This paper proposes a new approach to the investigation into aesthetics. Specifically, it~argues that it is possible to explain the aesthetic and its underlying dynamic relations with an~axiomatic structure (the octahedral axiom-derived category based on contemporary mathematics (namely category theory, and through this argument suggests the possibility for discussion about the mathematical structure of the aesthetic. If there were a way to describe the structure of the aesthetic with the language of mathematical structures and mathematical axioms---a~language completely devoid of arbitrariness---then we would make possible a universal argument about the essential human activity of ``the aesthetic'', and we would also gain a new method and viewpoint into the philosophy and meaning of the act of creating a work of art and artistic activities. This paper presents one mathematical structure as a foundation in constructing the science of dynamic aesthetics based on axiomatic functionalism, which is in turn based on a new interdisciplinary investigation into the generative structure of the aesthetic.

This study assessed the dynamic relationship between person and object in aesthetic experience. Patterns of the structure of aesthetic experience were derived from a conceptual model based on philosophical and psychological ideas. These patterns were further informed by interviewing individuals with extensive involvement in aesthetic activities and 25 secondary students. Accordingly, patterns were tested by developing a large pool of items attempting to identify measurable structural components of aesthetic experience. Refined first in a pilot study, the 36-item questionnaire was administered to 652 Greek students, aged from 13 to 15 years. Correlation matrices and exploratory factor analyses on principal components were used to examine internal structural relationships. The obliquely rotated five-factor solution of the refined instrument accounted for the 44.1% of the total variance and was combatible with the conceptual model of aesthetic experience, indicating the plausibility of both. The internal consistency of the items was adequate and external correlational analysis offered preliminary support for subsequent development of a self-report measure that serves to operationalize the major constructs of aesthetic experience in the general adolescent population. The results also raise theoretical issues for those interested in empirical aesthetics, suggesting that in experiential functioning, expressive perception and affect may play a more constructive role in cognitive processes than is generally acknowledged.

The history of beauty is as old as mankind itself--throughout history people have tried to improve their attractiveness and to enhance their beauty. The technical basis for many of nowadays procedures like lipoplasty, breast augmentation or rhinoplasty was thereby initiated more than a hundred years ago and evolved to the modern standards of today. The aim of this article is to recall the early days of aesthetic medicine and show the swift progress up to the highly specialized medical discipline of our modern time. Combining the past, present and future of aesthetic medicine, allows to incorporate this perspective and ultimately to delivery better patient care.

The biological roots of aesthetics and art.
Heinrich, Bernd
2013-07-18
Animals' choice behavior is driven by motivation that is attributable to both innate urges and from positive and negative reinforcements. Using a comparative approach as well as experimental evidence, I explore how the first involves fitness-enhancing benefits from aesthetics that are derived from ancestral choices via natural selection. Innate urges and aesthetics help guide animals to produce appropriate positive and negative choices that are species-specific. Choices of food, habitat and mates or associates are considered. I propose that art is not a uniquely human product, but a representation or an extension of the maker, as are the ornaments, displays, and songs of a bird.

Graph modeling systems and methods
Neergaard, Mike
2015-10-13
An apparatus and a method for vulnerability and reliability modeling are provided. The method generally includes constructing a graph model of a physical network using a computer, the graph model including a plurality of terminating vertices to represent nodes in the physical network, a plurality of edges to represent transmission paths in the physical network, and a non-terminating vertex to represent a non-nodal vulnerability along a transmission path in the physical network. The method additionally includes evaluating the vulnerability and reliability of the physical network using the constructed graph model, wherein the vulnerability and reliability evaluation includes a determination of whether each terminating and non-terminating vertex represents a critical point of failure. The method can be utilized to evaluate wide variety of networks, including power grid infrastructures, communication network topologies, and fluid distribution systems.

Results on graph turnpike problem without distinctness, including its NP-completeness, and an O(m+n log n) algorithm, is presented. The usual turnpike problem has all pairwise distances given, but does not specify which pair of vertices w e corresponds to. There are two other problems that can be viewed as special cases of the graph turnpike problem, including the bandwidth problem and the low-distortion graph embedding problem. The aim for the turnpike problem in the NP-complete is to orient the edges with weights w i in either direction so that when the whole cycle is transversed in the real line, it returns to a chosen starting point for the cycle. An instance of the turnpike problem with or without distinctness is uniquely mappable if there exists at most one solution up to translation and choice of orientation.

Negation switching invariant signed graphs
Directory of Open Access Journals (Sweden)
Deepa Sinha
2014-04-01
Full Text Available A signed graph (or, $sigraph$ in short is a graph G in which each edge x carries a value $\\sigma(x \\in \\{-, +\\}$ called its sign. Given a sigraph S, the negation $\\eta(S$ of the sigraph S is a sigraph obtained from S by reversing the sign of every edge of S. Two sigraphs $S_{1}$ and $S_{2}$ on the same underlying graph are switching equivalent if it is possible to assign signs `+' (`plus' or `-' (`minus' to vertices of $S_{1}$ such that by reversing the sign of each of its edges that has received opposite signs at its ends, one obtains $S_{2}$. In this paper, we characterize sigraphs which are negation switching invariant and also see for what sigraphs, S and $\\eta (S$ are signed isomorphic.

I introduce a continuous-time quantum walk on graphs called the quantum snake walk, the basis states of which are fixed-length paths (snakes) in the underlying graph. First, I analyze the quantum snake walk on the line, and I show that, even though most states stay localized throughout the evolution, there are specific states that most likely move on the line as wave packets with momentum inversely proportional to the length of the snake. Next, I discuss how an algorithm based on the quantum snake walk might potentially be able to solve an extended version of the glued trees problem, which asks to find a path connecting both roots of the glued trees graph. To the best of my knowledge, no efficient quantum algorithm solving this problem is known yet.
[A "dialogue" between the aesthetics of nursing and philosophy].
Chang, Chia-Hsiu; Chen, Chung-Hey
2012-02-01
Nursing aesthetics belong to the broader school of aesthetics, a branch of philosophy, as well as the nursing arts, an element of professional nursing. The philosophy of aesthetics recognizes the connection between an author and appreciators and identifies both substantive and abstract aesthetic experiences in interpersonal communication through the fine arts. Nursing aesthetics values the meaningful moments of patients, is sensitive to the influences of different circumstances and situations, and appreciates the unique qualities of humanness. Nursing aesthetics is emancipatory knowledge and involves empirical, ethical and personal knowing. The article is based on a search of OvidSP and Chinese Electronic Periodical Services (CEPS) database references using key words including aesthetic, aesthetics, art of nursing, or nursing aesthetics as well as a review of books related to aesthetics, knowledge construction, and nursing aesthetics. Authors determined definitions as defined by nursing experts and the applications thereof in clinical practice. This article aimed to illustrate that the ultimate concern of philosophy is "goodness" and that the foundation of caring behaviors is "love". In practice, nursing aesthetics is expressed through empathy, appreciation, inspiration and the therapeutic use of the self. Through aesthetic knowing and enhanced perceptual sensibility and reflection, nurses can transform intuitive knowing into art-acts and ultimately enhance nursing care quality.
Smyth, Charles Piazzi
Reprinted from the Memoirs of the Royal Astronomical Society 15, 1846, pp. 71-82. With annotations and illustrations added by Klaus Hentschel. The activities of the Astronomer Royal for Scotland, Charles Piazzi Smyth (1819-1900), include the triangulation of South African districts, landscape painting, day-to-day or tourist sketching, the engraving and lithographing of prominent architectural sites, the documentary photography of the Egyptian pyramids or the Tenerife Dragon tree, and `instant photographs' of the clouds above his retirement home in Clova, Ripon. His colorful records of the aurora polaris, and solar and terrestrial spectra all profited from his trained eye and his subtle mastery of the pen and the brush. As his paper on astronomical drawing, which we chose to reproduce in this volume, amply demonstrates, he was conversant in most of the print technology repertoire that the 19th century had to offer, and carefully selected the one most appropriate to each sujet. For instance, he chose mezzotint for the plates illustrating Maclear's observations of Halley's comet in 1835/36, so as to achieve a ``rich profundity of shadows, the deep obscurity of which is admirably adapted to reproduce those fine effects of chiaroscuro frequently found in works where the quantity of dark greatly predominates.'' The same expertise with which he tried to emulate Rembrandt's chiaroscuro effects he applied to assessing William and John Herschel's illustrations of nebulae, which appeared in print between 1811 and 1834. William Herschel's positive engraving, made partly by stippling and partly by a coarse mezzotint, receives sharp admonishment because of the visible ruled crossed lines in the background and the fact that ``the objects, which are also generally too light, [have] a much better definition than they really possess.'' On the other hand, John Herschel's illustration of nebulae and star clusters, given in negative, ``in which the lights are the darkest part of the

R2R - software to speed the depiction of aesthetic consensus RNA secondary structures
2011-01-01
Background With continuing identification of novel structured noncoding RNAs, there is an increasing need to create schematic diagrams showing the consensus features of these molecules. RNA structural diagrams are typically made either with general-purpose drawing programs like Adobe Illustrator, or with automated or interactive programs specific to RNA. Unfortunately, the use of applications like Illustrator is extremely time consuming, while existing RNA-specific programs produce figures that are useful, but usually not of the same aesthetic quality as those produced at great cost in Illustrator. Additionally, most existing RNA-specific applications are designed for drawing single RNA molecules, not consensus diagrams. Results We created R2R, a computer program that facilitates the generation of aesthetic and readable drawings of RNA consensus diagrams in a fraction of the time required with general-purpose drawing programs. Since the inference of a consensus RNA structure typically requires a multiple-sequence alignment, the R2R user annotates the alignment with commands directing the layout and annotation of the RNA. R2R creates SVG or PDF output that can be imported into Adobe Illustrator, Inkscape or CorelDRAW. R2R can be used to create consensus sequence and secondary structure models for novel RNA structures or to revise models when new representatives for known RNA classes become available. Although R2R does not currently have a graphical user interface, it has proven useful in our efforts to create 100 schematic models of distinct noncoding RNA classes. Conclusions R2R makes it possible to obtain high-quality drawings of the consensus sequence and structural models of many diverse RNA structures with a more practical amount of effort. R2R software is available at http://breaker.research.yale.edu/R2R and as an Additional file. PMID:21205310

Graph topologies on closed multifunctions
Directory of Open Access Journals (Sweden)
Giuseppe Di Maio
2003-10-01
Full Text Available In this paper we study function space topologies on closed multifunctions, i.e. closed relations on X x Y using various hypertopologies. The hypertopologies are in essence, graph topologies i.e topologies on functions considered as graphs which are subsets of X x Y . We also study several topologies, including one that is derived from the Attouch-Wets filter on the range. We state embedding theorems which enable us to generalize and prove some recent results in the literature with the use of known results in the hyperspace of the range space and in the function space topologies of ordinary functions.
Cyclic graphs and Apery's theorem

2002-01-01
This is a survey of results about the behaviour of Hermite-Pade approximants for graphs of Markov functions, and a survey of interpolation problems leading to Apery's result about the irrationality of the value ζ(3) of the Riemann zeta function. The first example is given of a cyclic graph for which the Hermite-Pade problem leads to Apery's theorem. Explicit formulae for solutions are obtained, namely, Rodrigues' formulae and integral representations. The asymptotic behaviour of the approximants is studied, and recurrence formulae are found
Interacting particle systems on graphs
Sood, Vishal
In this dissertation, the dynamics of socially or biologically interacting populations are investigated. The individual members of the population are treated as particles that interact via links on a social or biological network represented as a graph. The effect of the structure of the graph on the properties of the interacting particle system is studied using statistical physics techniques. In the first chapter, the central concepts of graph theory and social and biological networks are presented. Next, interacting particle systems that are drawn from physics, mathematics and biology are discussed in the second chapter. In the third chapter, the random walk on a graph is studied. The mean time for a random walk to traverse between two arbitrary sites of a random graph is evaluated. Using an effective medium approximation it is found that the mean first-passage time between pairs of sites, as well as all moments of this first-passage time, are insensitive to the density of links in the graph. The inverse of the mean-first passage time varies non-monotonically with the density of links near the percolation transition of the random graph. Much of the behavior can be understood by simple heuristic arguments. Evolutionary dynamics, by which mutants overspread an otherwise uniform population on heterogeneous graphs, are studied in the fourth chapter. Such a process underlies' epidemic propagation, emergence of fads, social cooperation or invasion of an ecological niche by a new species. The first part of this chapter is devoted to neutral dynamics, in which the mutant genotype does not have a selective advantage over the resident genotype. The time to extinction of one of the two genotypes is derived. In the second part of this chapter, selective advantage or fitness is introduced such that the mutant genotype has a higher birth rate or a lower death rate. This selective advantage leads to a dynamical competition in which selection dominates for large populations
DrawFromDrawings: 2D Drawing Assistance via Stroke Interpolation with a Sketch Database.
Matsui, Yusuke; Shiratori, Takaaki; Aizawa, Kiyoharu
2017-07-01
We present DrawFromDrawings, an interactive drawing system that provides users with visual feedback for assistance in 2D drawing using a database of sketch images. Following the traditional imitation and emulation training from art education, DrawFromDrawings enables users to retrieve and refer to a sketch image stored in a database and provides them with various novel strokes as suggestive or deformation feedback. Given regions of interest (ROIs) in the user and reference sketches, DrawFromDrawings detects as-long-as-possible (ALAP) stroke segments and the correspondences between user and reference sketches that are the key to computing seamless interpolations. The stroke-level interpolations are parametrized with the user strokes, the reference strokes, and new strokes created by warping the reference strokes based on the user and reference ROI shapes, and the user study indicated that the interpolation could produce various reasonable strokes varying in shapes and complexity. DrawFromDrawings allows users to either replace their strokes with interpolated strokes (deformation feedback) or overlays interpolated strokes onto their strokes (suggestive feedback). The other user studies on the feedback modes indicated that the suggestive feedback enabled drawers to develop and render their ideas using their own stroke style, whereas the deformation feedback enabled them to finish the sketch composition quickly.

In this paper, we first argue that drawing lines on polygons is harder than it may appear. We then propose two novel and robust techniques for a special case of this problem, namely wireframe drawing. Neither method suffers from the well-known artifacts associated with the standard two pass, offset...... based techniques for wireframe drawing. Both methods draw prefiltered lines and produce high-quality antialiased results without super-sampling. The first method is a single pass technique well suited for convex N-gons for small N (in particular quadrilaterals or triangles). It is demonstrated...
Engineering drawing from the beginning
Cousins, M F
1970-01-01
Engineering Drawing from the Beginning, Volume 2 discusses the methods for communicating technical engineering concepts through illustrations and drawings. This volume covers the more advance techniques in engineering drawing. The coverage of the text includes the helix, which is the path traced by a point moving uniformly around the surface of a right cylinder that is moving axially. The book also covers drawings of solid objects such as prisms, pyramids, and cones, along with hollow objects made from sheet material. In Chapter 5, the text presents the conventional representations of common
Blackness, religion, aesthetics: Johannes Anyuru’s literary explorations of migration and diaspora
Directory of Open Access Journals (Sweden)
Anne Heith
2014-07-01
Full Text Available The article analyses deconstructions of the European construct from the vantage point of how skin colour, physical appearance and religion have been used for drawing boundaries between white, Christian Europe and the black, Muslim world. The analysis is based on literary texts by the Afro-Swedish author Johannes Anyuru. The article proposes that his first collection of poems from 2003, the first novel from 2010 and a multifaceted text from 2011, which is a kind of diary on the surface level, contribute to the shaping of new notions of belonging, home and identity that challenge ideas of cultural purity and homogeneity. On the level of aesthetics the texts exemplify a diaspora aesthetic characterized by hybridization. This involves a mixture of elements from various stylistic registers and locations from within and outside Europe.
Crafty Entanglements: Knitting and Hard Distinctions in Aesthetics and Political Theory
Directory of Open Access Journals (Sweden)
Kate M. Daley
2013-01-01
Full Text Available Many theoretical writings on aesthetics and politics rely on hard distinctions between what is and is not art, and what is and is not political. In this article, I draw on the work of theorists, knitters, and fiber artists to argue that hand knitting provides a lens through which to unsettle some of these distinctions. I illustrate some of the ways in which aesthetic theory relies on hard distinctions between art and not-art and politics and not-politics, with particular focus on the work of Kant, Hegel, Heidegger, and Rancière. I explain how knitting is often seen as falling clearly outside the definitions of art and politics, and explore the surprising ways in which knitting shows the instability of these categories and expectations. I show that common social traditions and practices that often go unanalyzed can provide insight into the limitations and complexities of prevalent theoretical assumptions.
Maintaining "Synk" in Detroit: Two Case Studies in the Remix Aesthetic
Directory of Open Access Journals (Sweden)
Carleton S. Gholz
2011-03-01
Full Text Available Advances in audio-visual remixing technologies have produced a significant, largely unintended, consequence: audiences at EDM performances are dancing less—if at all. Instead, utilizing digital mobile devices, audiences have increasingly become interactive media producers within an environment encouraged by savvy, former DJs. Drawing from the fields of EDM studies, sound studies and film studies, I outline the historical arc of the remix aesthetic by comparing and contrasting recent work by two long-time EDM artists from the Detroit-Windsor region, Jeff Mills and Richie Hawtin. These two artists were central to the global proliferation of EDM culture during its mass-communication phase. However, in an era of heightened media convergence what scholars have traditionally understood as EDM has irreparably changed. Mills and Hawtin have much to contribute to this apparent impasse.Keywords: EDM, film studies, film sound, remix aesthetic, soundscape, media convergence, Jeff Mills, Richie Hawtin, Plastikman
Design and the question of contemporary aesthetic experiences

The article raises the question of the historical relativism of aesthetic experiences and argues that aesthetic experiences have changed according to new conditions in the contemporary age of globalization, mediatization and consumer culture. In this context, design gains attention as a primary...... case for aesthetic evaluation as design objects are, more than ever, framed and staged to be experienced aesthetically. Basing on this starting point, the article argues that an understanding of contemporary aesthetic experiences requires a meeting of cultural theory and philosophical approaches....... On the one hand, cultural theory is required to understand the changed conditions of the production, circulation and consumption of aesthetic meaning in cultural forms of art and design. On the other, philosophical aesthetics gives access to understanding the mechanisms of aesthetic judgments and how...
Combinatorial and geometric aspects of Feynman graphs and Feynman integrals
Energy Technology Data Exchange (ETDEWEB)
Bergbauer, Christoph
2009-06-11
The integrals associated to Feynman graphs must have been a source of frustration for particle physicists ever since. Indeed there is a delicate difference between being able to draw a Feynman graph and being able to compute the associated Feynman integral. Although perturbation theory has brought enormous breakthroughs, many physicists turned to more abstract developments in quantum field theory, looked for other ways to produce perturbational results, or left the field entirely. Nonetheless there is a significant number of physicists, computational and theoretical, who pursue the quest for concepts and algorithms to compute and understand those integrals to higher and higher orders. Their motivation is to help test the validity of the underlying physical theory. For a mathematician, Feynman graphs and their integrals provide a rich subject in their own right, independent of their computability. It was only recently though that the work of Bloch, Esnault and Kreimer has brought a growing interest of mathematicians from various disciplines to the subject. In fact it opened up a completely new direction of research: a motivic interpretation of Feynman graphs that unites their combinatorial, geometric and arithmetic aspects. This idea had been in the air for a while, based on computational results of Broadhurst and Kreimer, and on a theorem of Belkale and Brosnan related to a conjecture of Kontsevich about the generality of the underlying motives. A prerequisite for the motivic approach is a profound understanding of renormalization that was established less recently in a modern language by Connes and Kreimer. This dissertation studies the renormalization of Feynman graphs in position space using an adapted resolution of singularities, and makes two other contributions of mostly combinatorial nature to the subject. I hope this may serve as a reference for somebody who feels comfortable with the traditional position space literature and looks for a transition to the

Multiple graph regularized protein domain ranking
Wang, Jim Jing-Yan
2012-11-19
Background: Protein domain ranking is a fundamental task in structural biology. Most protein domain ranking methods rely on the pairwise comparison of protein domains while neglecting the global manifold structure of the protein domain database. Recently, graph regularized ranking that exploits the global structure of the graph defined by the pairwise similarities has been proposed. However, the existing graph regularized ranking methods are very sensitive to the choice of the graph model and parameters, and this remains a difficult problem for most of the protein domain ranking methods.Results: To tackle this problem, we have developed the Multiple Graph regularized Ranking algorithm, MultiG-Rank. Instead of using a single graph to regularize the ranking scores, MultiG-Rank approximates the intrinsic manifold of protein domain distribution by combining multiple initial graphs for the regularization. Graph weights are learned with ranking scores jointly and automatically, by alternately minimizing an objective function in an iterative algorithm. Experimental results on a subset of the ASTRAL SCOP protein domain database demonstrate that MultiG-Rank achieves a better ranking performance than single graph regularized ranking methods and pairwise similarity based ranking methods.Conclusion: The problem of graph model and parameter selection in graph regularized protein domain ranking can be solved effectively by combining multiple graphs.

Foucault, Counselling and the Aesthetics of Existence
Peters, Michael A.
2005-01-01
Michel Foucault was drawn late in life to study the "arts of the self" in Greco-Roman culture as a basis, following Nietzsche, for what he called an "aesthetics of existence." By this, he meant a set of creative and experimental processes and techniques by which an individual turns him- or herself into a work of art. For Nietzsche, it was above…

Jacques Joseph: Father of modern aesthetic surgery

Full Text Available When we review the history of modern aesthetic surgery, a name that stands out as bright as a beacon and precious as gold is undoubtedly that of Jacques Joseph. A surgeon, par excellence, far ahead of his time, who chose to think out of the box, Joseph, despite all odds set out to give respectability to Aesthetic Surgery without depriving it of any scientific core values. By his words and deeds proved beyond doubt that only the very best in the field of reconstructive surgery, can visualize the hidden perfection in imperfection and formulate a treatment plan and a surgical strategy to achieve that elusive perfection. The rich surgical literature that he has left behind, the wealth of surgical instruments that he had designed and above all a way of thinking that he propagated, that aesthetic surgery is not frivolous but very serious endeavor, and treating the psychology of the patient is as important as treating his disease, undoubtedly makes him the revered ′Father of Modern Aesthetic Surgery′.

Aesthetic Solidarity "after" Kant and Lyotard

One of the most complex issues in Kant's "Critique of Judgment" is the aesthetic judgment's claim to universal validity and shareability. Kant is not very clear about the exact status of this claim. Kant's distinction between the beautiful and the sublime only complicates the matter, since the universal shareability of the judgment of the sublime…

Kant's "Critique of Judgment," which was published in 1790, referred in detail to the affinity between beauty and morality. Schiller's writings from the 1790s dealing with aesthetics and ethics are intertwined, simultaneously, both with an affirmative reception of Kant's ideas and with critical attitudes against them. This applies to essays such…
Social aesthetics and the management of addiction.
Musalek, Michael
2010-11-01
One of the main causes of nonadherence is that the goals and forms of addiction treatment are not sufficiently attractive. To study the attractiveness of treatment in clinical practice inevitably means to enter the field of social aesthetics. The call for the implementation of social aesthetics in practice results in a shift of paradigms in the treatment of patients suffering from dependence syndromes. The main themes in the literature covered by the article focus on the role of social aesthetics in medicine in general, as well as on the attractiveness of addiction treatment, in particular. When treatment objectives and programmes become more attractive the result will be reduced drop-out rates, and in turn an increase of treatment effectiveness. Transferring theory of social aesthetics to clinical practice, the Anton Proksch Institute's Orpheus Programme is concerned with opening up spaces and creating atmospheres in which it becomes possible for the individual addicts to realise their possibilities. The challenge in the therapeutic process is not only to recognise the significance of the disorders' pathology but also to find ways out of the imagined impossibilities by opening up new possibilities and uncovering resources of the suffering human.
[The aesthetic character of caring knowledge].
Tsai, Cheng-Yun
2013-08-01
The identity of nursing is founded on caring knowledge, which is derived from our understanding of its experience-revealed essence. This purposive knowledge differs from scientific knowledge because validity guides the latter and ethics guides the former. Therefore, justifying the objectivity of caring knowledge should be based on the aesthetic character of this knowledge rather than on a general social-science explanation.

Studies in Cup Drawing Behavior of Polymer Laminated Sheet Metal
Elnagmi, M.; Jain, M.; Bruhis, M.; Nielsen, K.
2011-08-01
Axisymmetric deep drawing behavior of a polymer laminated sheet metal (PLSM) is investigated using an axisymmetric cup drawing test. PLSMs are of interest as a replacement for painted finishes for automotive applications as they have the potential to achieve good quality long lasting and aesthetically appealing surfaces on stamped parts. However, there is limited understanding of PLSMs in automotive deep drawing situations to produce complex 3-D parts. The tests are carried out using well-controlled, laboratory-based, dual-action, servo-hydraulic forming presses under blank-holder force and punch displacement control conditions. An optical strain mapping system is used to measure the surface strains (and to construct 3D strain maps) from the film side of the deformed samples for a range of forming conditions. Deep drawing characteristics such as punch load versus punch displacement traces, strain distribution along the cup profile, flange wrinkling and fracture characteristics are experimentally assessed for stainless steel-plastic film laminated sheet materials. Also the effect of lamination pressure on wrinkling and delamination is investigated for a decorative pressure sensitive adhesive film affixed to the stainless steel sheet.
Purists, Partisans, and the Aesthetic Dimension of Sport
Charles Robinson
2014-01-01
Purists, Partisans, and the Aesthetic Dimension of Sport Stephen Mumford, in his book Watching Sport, identifies two types of sports spectator – partisans and purists. Partisans are more concerned to see their team win, whether they do so in an aesthetically pleasing way or not, while purists have no such irrational commitment, and instead pursues the higher aesthetic experience of sport. The purist, Mumford argues, is superior because she watches sport for aesthetic and intellectual reas...
Aesthetic Appreciation, Ethics, and 9/11
Directory of Open Access Journals (Sweden)
Emmanouil Aretoulakis
2008-01-01
Full Text Available There have been numerous critical articles on what really happened on the otherwise beautiful morning of 11 September 2001. Beyond doubt, the bulk of the critical responses to the terrorist attacks focused on the ethical and humanitarian, or rather the unethical and inhumane implications of the atrocious act, leaving no room for any philosophical reflection on the potential assessment or reception of the event from the perspective of art and aesthetics. The few years that have gone by since 2001 have provided us with some a sense of emotional detachment from the horror of that day, a detachment that may have awakened our aesthetic and artistic instincts with regard to the attacks themselves as well as their visual representation. Chronological distance renders an unprejudiced and independent stance more possible now than ever. It also allows us to reconsider our initial politically correct and ethically justified repulsion of the efforts made by a few artists to aestheticize 9/11. Such repulsion, however, was associated with the delusion that by denouncing aesthetics we were really securing the prevalence of politics, morality and ethical responsibility in a terror-afflicted society. My point in this paper is that there is a need for aesthetic appreciation when contemplating a violent event such as the 9/11 terrorist attacks. What is more, appreciation of the beautiful, even in case of a 9/11, seems necessary because it is a key to establishing an ethical stance towards terror, life, and art. It should be stressed that independent aesthetic experience is not important in itself but is a means of cultivating an authentic moral and ethical judgment.
The Cosmological Potential of Byzantine Ascetic Aesthetics
Directory of Open Access Journals (Sweden)
Аndrey Tsarenok
2017-09-01
Full Text Available The study explores the peculiarities of the cosmological senses, which exist in Byzantine ascetic aesthetical doctrine. Underlining the obvious strong connection between theological aesthetics, ontology and cosmology, the author of the article points out the interpretation of world’s beauty, order and harmony by representatives of ascetic culture of Byzantium (sts. Grigoriy the Theologian, Grigoriy, bishop of Niss, Ioann Chrysostom, Ioann Damaskin, Simeon the New Theologian and others. The aesthetics of the asceticism is characterized as theocentrical ontology of beauty. Its development has been influenced by theism, trinitary monotheism and theocentrism of Christian world-view tradition. The theologians speak about the existence of the Highest Absolute Beauty, Who is the cause of the beautiful things in created reality. The impressive qualities of cosmos are considered as evidence of being of their Almighty Creator. Therefore, the sensual cognition can help believer in his or her search of God. At the same time, ascetic aesthetics prevents from unreasonable enjoying of the sensual (material, somatic beauty for such enjoying is able to make the true person’s spiritual perfection impossible. Moreover, according to Christian theology, absolutization of the cosmical beauty regularly distorts the person’s belief: Byzantine ascetics point out the “aesthetical” cause of paganism appearance. Appealing to Bible, theologians differentiate two periods in history of cosmos, which can be interpreted as the pre-sin and the post-sin ones. The beginning of visible world existence was marked with being of original beauty, order and harmony, but the transgression, committed by the first people, distorted the cosmos to a great degree. Acknowledging of this sorrowful fact does not ruin quite an optimistic character of ascetic aesthetical, ontological and cosmological conceptions of Byzantium. According to them, the beauty of Universe will be completely

Evolutionary graph theory (EGT) is recently proposed by Lieberman et al. in 2005. EGT is successful for explaining biological evolution and some social phenomena. It is extremely important to consider the time of fixation for EGT in many practical problems, including evolutionary theory and the evolution of cooperation. This study characterizes the time to asymptotically reach fixation.
