Kinds of Editing Terms modified by Editing Selected AbstractsQuantitative solid-state 13C NMR spectroscopy of organic matter fractions in lowland rice soilsEUROPEAN JOURNAL OF SOIL SCIENCE, Issue 2 2004R. J. Smernik Summary Spin counting on solid-state 13C cross-polarization (CP) nuclear magnetic resonance (NMR) spectra of two humic fractions isolated from tropical lowland soils showed that only 32,81% of potential 13C NMR signal was detected. The observability of 13C NMR signal (Cobs) was higher in the mobile humic acid (MHA) than in the calcium humate (CaHA) fraction, and increased with increasing intensity of irrigated rice cropping. NMR observability appeared to be related to the nature of the organic carbon, with phenol- and methoxyl-rich samples having the higher values of Cobs. The Bloch decay (BD) technique provided more quantitatively reliable 13C NMR spectra, as evidenced by values of Cobs in the range 91,100% for seven of the eight humic fractions studied. The BD spectra contained considerably more aryl and carbonyl signal, and less O,alkyl and alkyl signal, with the greatest differences between CP and BD spectra observed for the samples with low Cobs(CP). The causes of low CP observability were investigated using the spectral editing technique RESTORE ( REstoration of Spectra via TCH and T One Rho (T1,H) Editing). Rapid T1,H relaxation was found to be primarily responsible for the under-representation of carbonyl carbon, whereas inefficient cross-polarization was primarily responsible for the under-representation of aryl carbon in CP spectra. Proton NMR relaxation rates T1H and T1,H were found to correlate with other NMR properties and also with cropping management. Non-uniform rates of T1H relaxation in two of the CaHA fractions enabled the generation of proton spin relaxation editing subspectra. [source] Development Section, April 2008GEOGRAPHY COMPASS (ELECTRONIC), Issue 3 2008Cheryl McEwan EDITORIAL It is a great privilege to serve as Editor for the Development section of Geography Compass. The journal is an exciting new venture in electronic publishing that aims to publish state-of-the-art peer-reviewed surveys of key contemporary issues in geographical scholarship. As the first Editor of this section, it is my responsibility to establish the key aims and innovations for this section of the journal. These include: publishing reviews of scholarship on topics of contemporary relevance that are accessible and useful to researchers, teachers, students and practitioners; developing the range of topics covered across the spectrum of development geography; helping to set agendas in development geography by identifying gaps in existing empirical and conceptual research; commissioning articles from both established and graduate/early career researchers who are working at the frontiers of development geography; and communicating the distinctiveness of Geography Compass. Part of this distinctiveness is in publishing articles that are both of scholarly excellence and accessible to a wide audience. The first volume of Geography Compass was published in 2007, covering a wide range of topics (e.g. migration, children, technology, grassroots women's organizations, civil society, biodiversity, tourism, inequality, agrarian change, participatory development, disability, spirituality) in a number of specific geographical areas (e.g. Africa/southern Africa, Caribbean, China, Peru). Forthcoming in 2008/2009 are articles on the Gambia, Latin America, the Philippines, Southeast Asia, Bangladesh and South Africa, focusing on topics such as food security, comparative post-socialism, foreign aid and fair trade. Building on these diverse and excellent articles, I plan to communicate the distinctiveness of Development in a number of ways. First, I encourage an ecumenical approach to the notion of ,development geography' and welcome contributions from scholars across a range of social science disciplines whose work would be useful to a geography audience. This is important, not least because both development and geography, in disciplinary terms, are largely European inventions. Many scholars in Latin America, Africa and Asia, for example, do not refer to themselves as either development specialists or geographers but are producing important research in areas of direct relevance to students and researchers of ,development geography'. As the first editions illustrate, I also seek to publish articles that reflect ,development' in its broadest sense, encompassing economic, (geo)political, social, cultural and environmental issues. 2008 will be an interesting year for development, with a number of important issues and events shaping discourse and policy. These include: the Beijing Olympics and increasing focus on China's role in international development; political change in a number of African countries (Kenya, Zimbabwe, South Africa); the US presidential elections and potential shifts in policy on climate change, trade and security; the impacts of the Bali roadmap on climate change in the current economic context; the increasing number of impoverished people in Asia (notably China and India), sub-Saharan Africa and Latin America (notably Brazil) that even the World Bank has acknowledged; the implications of the increasing role of philanthropic foundations (e.g. the Gates Foundation and those emerging in India and Russia) in international development. I hope to see some of these issues covered in this journal. Second, I am keen to break down the association between ,development' and parts of the world variously categorized as ,Third World', ,Global South' or ,Developing World' by publishing articles that cut across North and South, East and West. The intellectual and disciplinary practices within (Western) geography that separate those researching issues in the South and post-socialist contexts from those researching similar issues in advanced capitalist economies are, it seems, no longer sustainable or sensible. Moreover, while studies of transnational and ethical trade, neoliberalism, household economies and ,commodity chains', for example, incorporate a multitude of case studies from across the world, these tend to be understood through conceptual lenses that almost always have their theoretical antecedents in Western theorization. The notion of ,learning from' debates, policy and practice in other parts of the world is still relatively alien within the discipline. There are thus issues in how we research and teach ethically and responsibly in and about different parts of the world, and in which this journal might make a contribution. Third, and related, part of my responsibility is to ensure that Compass reflects the breadth of debate about ,development' by publishing articles written by a truly international range of scholars. This has proved to be a challenge to date, in part reflecting the newness of the journal and the difficulties posed by English language publication. However, an immediate aim is to publish the work and ideas of scholars based outside of Anglophone contexts, in the Global South and in post-socialist contexts, and to use international referees who are able to provide valuable commentaries on the articles. A longer-term aim is to also further internationalize the Editorial Board. Currently, one-third of the Editorial Board is non-UK and I plan to increase this to at least 50% in future. Fourth, I plan to ensure that the Development section takes full advantage of electronic publication and the opportunities this offers. Thus, while I am keen to retain a word limit in the interest of publishing accessible articles, the lack of constraint regarding page space enables authors to include a wide range of illustrative and other material that is impossible in print journals. I plan to encourage authors to make greater use of visual materials (maps, photographs/photo-essays, video, sound recordings, model simulations and datasets) alongside text as well as more innovative forms of presentation where this might be appropriate. Finally, in the coming year, I intend to work more closely with other Compass section Editors to realize the potential for fostering debate that cuts across subdisciplinary and even disciplinary boundaries. The journal publishes across the full spectrum of the discipline and there is thus scope for publishing articles and/or special issues on development-related topics that might best be approached through dialogue between the natural and social sciences. Such topics might include resources (e.g. water, oil, bio-fuels), hazard and risk (from environmental issues to human and state security), and sustainability and quality of life (planned for 2008). Part of the distinctiveness of Compass is that electronic-only publication ensures that articles are published in relatively quick time , in some cases less than 3 months from initial submission to publication. It thus provides an important outlet for researchers working in fast-changing contexts and for those, such as graduate and early-career researchers, who might require swift publication for career purposes. Of course, as Editor I am reliant on referees both engaging with Manuscript Central and providing reports on articles in a relatively short space of time to fully expedite the process. My experience so far has been generally very positive and I would like to thank the referees for working within the spirit of the journal. Editing a journal is, of course, a collaborative and shared endeavour. The Development Editorial Board has been central to the successful launch of Development by working so generously to highlight topics and potential authors and to review articles; I would like to take this opportunity to thank Tony Bebbington, Reg Cline-Cole, Sara Kindon, Claire Mercer, Giles Mohan, Warwick Murray, Richa Nagar, Rob Potter, Saraswati Raju, Jonathan Rigg, Jenny Robinson and Alison Stenning. The Editors-in-Chief , Mike Bradshaw and Basil Gomez , have provided invaluable advice while adding humour (and colour) to the editorial process. Colleagues at Wiley-Blackwell have provided superb support, in particular, Helen Ashton who is constantly on hand to provide advice and assistance. I look forward to working closely with these people again in the coming year, as well as with the authors and readers who are vital to ensuring that Geography Compass fulfils its remit. [source] Berthold Auerbach's Deutscher Volks-Kalender: Editing as Political AgendaGERMAN LIFE AND LETTERS, Issue 1 2002Kristina R. Sazaki An analysis of Berthold Auerbach's Deutscher Volks-Kalender (1858,69) reveals how Auerbach attempted to participate in and to shape the discourse on national identity. One of the most popular writers of his day, he used his position as editor to carry out a political agenda that advocated German unification. He attempted to unify the diverse strata of society by providing specific ideas and values , above all on German unification and emigration , that would be understood and accepted by the practical as well as the literary reader. Many stories and essays called directly or indirectly for a united Germany. Others dealt with the hot topic of America during the Civil War as a means to encourage Germans to remain in Germany. Auerbach routinely engaged like-minded contributors from the fields of politics, science, sociology, and the arts to create a multidisciplinary forum on nationhood. By employing images of family, friendship, and the organic and also by conjuring up a common literary tradition in Friedrich Schiller, Auerbach projected his concept of nation onto a popular form of mass culture , the calendar.

Reflections on Editing the Journal of Management StudiesJOURNAL OF MANAGEMENT STUDIES, Issue 1 2009Timothy Clark First page of article [source] The large form of ADAR 1 is responsible for enhanced hepatitis delta virus RNA editing in interferon- , -stimulated host cellsJOURNAL OF VIRAL HEPATITIS, Issue 3 2006D. Hartwig Summary., Hepatitis delta virus (HDV) RNA editing controls the formation of hepatitis-delta-antigen-S and -L and therefore indirectly regulates HDV replication. Editing is thought to be catalysed by the adenosine deaminase acting on RNA1 (ADAR1) of which two different forms exist, interferon (IFN)- , -inducible ADAR1-L and constitutively expressed ADAR1-S. ADAR1-L is hypothesized to be a part of the innate cellular immune system, responsible for deaminating adenosines in viral dsRNAs. We examined the influence of both forms on HDV RNA editing in IFN- , -stimulated and unstimulated hepatoma cells. For gene silencing, an antisense oligodeoxyribonucleotide against a common sequence of both forms of ADAR1 and another one specific for ADAR1-L alone were used. IFN- , treatment of host cells led to approximately twofold increase of RNA editing compared with unstimulated controls. If ADAR1-L expression was inhibited, this substantial increase in editing could no longer be observed. In unstimulated cells, ADAR1-L suppression had only minor effects on editing. Inhibition of both forms of ADAR1 simultaneously led to a substantial decrease of edited RNA independently of IFN- , -stimulation. In conclusion, the two forms of ADAR1 are responsible almost alone for HDV editing. In unstimulated cells, ADAR1-S is the main editing activity. The increase of edited RNA under IFN- , -stimulation is because of induction of ADAR1-L, showing for the first time that this IFN-inducible protein is involved in the base modification of replicating HDV RNA. Thus, induction of ADAR1-L may at least partially cause the antiviral effect of IFN- , in natural immune response to HDV as well as in case of therapeutic administration of IFN. [source] Shakespearean Editing and Why It MattersLITERATURE COMPASS (ELECTRONIC), Issue 1 2005Leah Marcus A generation ago, many Shakespearean scholars simply accepted the versions of the play that they were provided with by editors. So long as the label was right , Arden, Oxford, Cambridge, Penguin, Riverside, Pelican , the content was assumed to be reliable. But editing can never be transparent , it is always influenced by the cultural assumptions of the editor and his or her era, however submerged those assumptions may be in terms of the editor's stated textual practices. In the late twentieth and twenty-first centuries, as a result of feminist and postcolonial critical approaches to Shakespearean texts, we have begun to realize the degree to which our inherited editions are shaped in accordance with assumptions about colonialism, race, and the status of women that are no longer acceptable to us, and that in fact distort elements of Shakespeare's plays as they exist in early printed quarto and folio versions. As earlier disciplinary boundaries between editing and criticism have broken down, Shakespearean critics have increasingly turned to editing in order to undo some of the racist and sexist assumptions behind our received texts of the plays.

[source] Brain GABA editing by localized in vivo1H magnetic resonance spectroscopyNMR IN BIOMEDICINE, Issue 2 2004G. Bielicki Abstract Editing of GABA by 1H MRS in a specific brain area is a unique tool for in vivo non-invasive investigation of neurotransmission disorders. Selective GABA detection is achieved using sequences based on double quantum coherence (DQC). Our pulse sequence makes accurate measurements without artefacts due to spatial localization. The sequence was tested on a phantom solution. The effect of vigabatrin, a specific inhibitor of GABA transaminase, was measured in rat brain and GABA detection was performed in vivo in monkey brain using this procedure. Rats were spilt into two groups. In the control group, the rats had access to water and, in the other group (vigabatrin, VGB, rats), animals were allowed free access to drinking water containing vigabatrin. After 3 weeks of treatment, rats were anesthetized for in vivo NMR spectroscopy investigation. At the end of the experiment, brains were quickly removed, freeze-clamped and extracted with 4% perchloric acid. One part of the acid extract was used for GABA concentrations assessment by ion exchange chromatography with ninhydrin detection. The second was used for high-resolution NMR analysis. By chromatography measurements, the GABA concentration was 1.23±0.06,,mol/g for controls, while for vigabatrin-treated rats the GABA concentration was 4.89±1.60,,mol/g. The NMR in vivo results were closely correlated with the NMR ex vivo (r=0.99, p<0.01) and chromatography results (r=0.98, p<0.01). The correlation between ex vivo results and chromatography results was also high (r=0.99, p<0.001). This pulse sequence performed GABA editing from a 376,,l voxel located on the right basal ganglia area in a non-human primate brain. This in vivo GABA editing scheme can thus be proposed for accurate measurement of brain GABA concentrations. Copyright © 2004 John Wiley & Sons, Ltd. [source] Editing as a psychological practiceTHE JOURNAL OF ANALYTICAL PSYCHOLOGY, Issue 3 2006John Beebe Abstract:, The experience of the Jungian analyst in the role of editor of manuscripts by creative colleagues is examined. Historical precedents include Michael Fordham's editorial correspondence with Jung around the latter's synchronicity essay; Jung's handling of manuscripts submitted by Sabina Spielrein to the Jahrbuch für psychoanalytische und psychopathologische Forschungen and various authors to the Zentralblatt für Psychotherapie und ihre Grenzgebiete, and the author's close editing of a paper submitted by Andrew Samuels to the Journal of Analytical Psychology. In addition to mustering an adequate amount of generosity, erudition, and availability, the analytic editor must know how to clarify a psychological argument and to gauge the psychological impact of the written text. Notwithstanding transference/countertransference phenomena that can emerge around issues of competition, envy, and territoriality when author and editor are also fellow-authors working in the same field, the editor needs to be comfortable about serving as the author's selfobject and midwife. From an analytic perspective, although communicating decisions about the best way to put ideas into words can sometimes attract transference to the editor, the more profound transference that analysts experience in the editing situation is toward the text being edited, which helps to motivate donated time spent caring for journal manuscripts. [source] Mitochondrial Cytochrome b mRNA Editing in Dinoflagellates: Possible Ecological and Evolutionary Associations?THE JOURNAL OF EUKARYOTIC MICROBIOLOGY, Issue 6 2005HUAN ZHANG Abstract. To verify the hypothesis that mt mRNA editing is widespread in dinoflagellates, we analyzed cytochrome b (cob) mRNA editing for six species representing distinct ecotypes and taxonomic classes of Dinophyceae. Editing is detected in all, which is similar to the three other species studied previously in that edited sites appear to aggregate in four clusters and occur predominantly at first and second positions of codons (93%), overwhelmingly involving A,G, U,C, or C,U substitutions with a smaller number of G,C, G,A changes. Comparative analyses on editing characteristics reveal interesting trends related to phylogenetic relatedness and ecological features. Editing density (percentage of nucleotide that is affected by editing) increases from early to derived lineages. Higher editing densities also map to red tide-forming lineages. Furthermore, similarity of location of edited codons (LOE) and the type of nucleotide changes (TOE) in different lineages mirror the taxonomic affinity of the lineages. Phylogenetic trees constructed from LOE and TOE resemble those inferred from cob sequences. The results bolster our earlier hypothesis that cob editing is widespread in dinoflagellates and suggest that density, location, and type of editing may bear yet-to-be-defined evolutionary and ecological significance. [source] Substrate and cofactor requirements for RNA editing of chloroplast transcripts in Arabidopsis in vitroTHE PLANT JOURNAL, Issue 1 2005Carla E. Hegeman Summary None of the macromolecular components of the chloroplast RNA editing apparatus has yet been identified. In order to facilitate biochemical purification and characterization of the chloroplast RNA editing apparatus, we have identified conditions suitable for production of chloroplast extracts from the model plant Arabidopsis that are capable of editing exogenous substrates produced by in vitro transcription. A simple poisoned primer extension assay readily quantified editing extent of mutated and wild-type substrates. Maximum editing efficiency typically varied from 10 to 40% with different chloroplast preparations. Substrates carrying as little as 47 nt surrounding the psbE editing site were as efficiently edited as longer substrates. Editing activity was stimulated when either ATP, CTP, or dCTP was provided to the extract, an unusual observation also recently seen with plant mitochondrial editing extracts. Editing was sensitive to a zinc chelator, also a characteristic of the mammalian APOBEC editing enzyme, which is a zinc-dependent cytidine deaminase. [source] Ectopic Beats in Heart Rate Variability Analysis: Effects of Editing on Time and Frequency Domain MeasuresANNALS OF NONINVASIVE ELECTROCARDIOLOGY, Issue 1 2001Mirja A. Salo M.Sc. Background: Various methods can be used to edit biological and technical artefacts in heart rate variability (HRV), but there is relatively little information on the effects of such editing methods on HRV. Methods: The effects of editing on HRV analysis were studied using R-R interval data of 10 healthy subjects and 10 patients with a previous myocardial infarction (Ml). R-R interval tachograms of verified sinus beats were analyzed from short-term (,5 min) and long-term (,24 hours) recordings by eliminating different amounts of real R-R intervals. Three editing methods were applied to these segments: (1) interpolation of degree zero, (2) interpolation of degree one, and (3) deletion without replacement. Results: In time domain analysis of short-term data, the standard deviation of normal-to-normal intervals (SDANN) was least affected by editing, and 30%-50% of the data could be edited by all the three methods without a significant error (< 5%). In the frequency domain analysis, the method of editing resulted in remarkably different changes and errors for both the high-frequency (HF) and the low-frequency (LF) spectral components. The editing methods also yielded in different results in healthy subjects and AMI patients. In 24-hour HRV analysis, up to 50% could be edited by all methods without an error larger than 5% in the analysis of the standard deviation of normal to normal intervals (SDNN). Both interpolation methods also performed well in the editing of the long-term power spectral components for 24-hour data, but with the deletion method, only 5% of the data could be edited without a significant error. Conclusions: The amount and type of editing R-R interval data have remarkably different effects on various HRV indices. There is no universal method for editing ectopic beats that could be used in both the time-domain and the frequency-domain analysis of HRV.

The Hamar woman in the photo bears marks of whipping, a subject which raised the first divisions between Gardner and anthropologists Ivo Strecker and Jean Lydall, as Gardner was inclined to see the practice as a facet of female subordination and male cruelty. The Streckers, after many years of research, took a different view, which can be grasped in Jean Lydall's article ,Beating around the bush' (see http://www.uni-mainz.de/organisationen/SORC/fileadmin/texte/lydall/Beating) Gardner makes clear his feelings in this note, highlighted in his book The impulse to preserve: ,Editing the Rivers of sand imagery made a huge impression on me. I kept being reminded that I especially disliked Hamar man and I don't think I would have felt differently had there been no Women's Movement. I don't see how anyone can escape feeling the same way once they see the film. It was a painful life for both sexes. So why not say so? I don't think anthropology is doing its job by being value free. I do think it should accept responsibility to look for larger truths.'

The Declaration sets the minimum international standards for the promotion and protection of indigenous peoples' rights. The display boards capture the historic moment on 13 September 2007, when UN member states overwhelmingly supported the adoption of the Declaration at the General Assembly's 61st session. Votes in favour of the Declaration are shown in green (143 + 1 not shown), abstentions in orange (11) and votes against in red (4). With the exception of Montenegro, whose vote in favour did not register on screen, absent or non-voting states are blank. Such overwhelming support within the General Assembly was by no means guaranteed , it was the outcome of lengthy and delicate behind-the-scenes negotiations. Expectations that the Declaration would be adopted in December 2006 were dashed when the African Group of countries blocked it, claiming that, despite 23 years of negotiations, more time was needed for consultation. In the ensuing period, Mexico, Peru and Guatemala, as co-sponsors of the Declaration, took the lead in negotiating an agreement with the African Group that they would support a Declaration with three main amendments, and would block other amendments or delays put forward by Australia, Canada, the US and New Zealand. The co-sponsors then sought agreement to this amended Declaration from the Global Indigenous Peoples' Caucus, who engaged in their own worldwide consultation process with indigenous peoples' organizations. The outcome remained uncertain, however, until these giant screens in the UN General Assembly Hall finally flashed green, to spontaneous applause from the delegates and their supporters. Since anthropologists work with indigenous peoples worldwide, this historic vote raises the challenge of how they, individually and as a discipline, position themselves in relation to the new Declaration.

The resulting products provided first insights into the cytotoxicity profile of these extremely scarce macrolides. Deliberate deviations from the previously described total syntheses of amphidinolide X (1) and Y (2) allowed a collection of seven designed analogues of these extremely scarce marine natural products to be obtained. These fully synthetic "natural product-like" compounds enabled first insights into the previously unknown structure,activity relationships governing this series. Although the average cytotoxicity is moderate, it was found that certain bladder, colon and prostate cancer cell lines are fairly sensitive, and that the best synthetic analogues are more active than the natural products themselves. The syntheses rely on the 9-MeO-9-BBN variant of the Suzuki coupling for the formation of the carbon frameworks, as well as on Yamaguchi lactonization reactions for the cyclization of the macrocyclic rings.

Meanwhile the process of reviewing and rehabilitating unfashionable or neglected writers and consigning others to the periphery will go on, although a core of major authors will continue to attract scholarly and critical attention. There will be an increasing focus on the new histories of the book, on authorship and readership. Research on print culture in its widest sense will expand in the wake of the ongoing digitisation of printed materials, a process which ultimately will transform the way we do research. The focus on writers and texts will move from a metropolitan-centred one to embrace the literatures in English of the countries of the Empire and of North America, and more problematically, to include the literature and culture of Europe in the nineteenth century. The latter development poses a challenge to the hitherto monolingual nature of Victorian literary studies. Finally there will be a continued engagement in multi-disciplinary, cross-disciplinary if not truly interdisciplinary work that has been characteristic of Victorian Studies since its emergence in the 1950s.

These range from undergraduate resistance to reading long novels, to the funding councils' apparent preference for collaborative, interdisciplinary or large editorial projects, and proposed changes such as the Block Grants Partnership Scheme. The decline of ,feminist' in favour of ,gendered' critical approaches, and preference for generic and cultural issues over single author studies, mark a notable change of approach in the last few years. Although continuing loyalty towards historicism, and rejection of the more abstract literary theories of the 1990s, suggest that Victorian literary studies remains confident of its own direction in the next five years, the essay closes with a hope that the purely ,literary' analysis will not disappear for ever. [source] Performance-driven muscle-based facial animationCOMPUTER ANIMATION AND VIRTUAL WORLDS (PREV: JNL OF VISUALISATION & COMPUTER ANIMATION), Issue 2 2001Byoungwon Choe Abstract We describe a system to synthesize facial expressions by editing captured performances. For this purpose, we use the actuation of expression muscles to control facial expressions. We note that there have been numerous algorithms already developed for editing gross body motion. While the joint angle has direct effect on the configuration of the gross body, the muscle actuation has to go through a complicated mechanism to produce facial expressions. Therefore,we devote a significant part of this paper to establishing the relationship between muscle actuation and facial surface deformation. We model the skin surface using the finite element method to simulate the deformation caused by expression muscles. Then, we implement the inverse relationship, muscle actuation parameter estimation, to find the muscle actuation values from the trajectories of the markers on the performer's face. Once the forward and inverse relationships are established, retargeting or editing a performance becomes an easy job. We apply the original performance data to different facial models with equivalent muscle structures, to produce similar expressions. We also produce novel expressions by deforming the original data curves of muscle actuation to satisfy the key-frame constraints imposed by animators.Copyright © 2001 John Wiley & Sons, Ltd. [source] TouchTone: Interactive Local Image Adjustment Using Point-and-SwipeCOMPUTER GRAPHICS FORUM, Issue 2 2010Chia-Kai Liang Recent proliferation of camera phones, photo sharing and social network services has significantly changed how we process our photos. Instead of going through the traditional download-edit-share cycle using desktop editors, an increasing number of photos are taken with camera phones and published through cellular networks. The immediacy of the sharing process means that on-device image editing, if needed, should be quick and intuitive. However, due to the limited computational resources and vastly different user interaction model on small screens, most traditional local selection methods can not be directly adapted to mobile devices. To address this issue, we present TouchTone, a new method for edge-aware image adjustment using simple finger gestures. Our method enables users to select regions within the image and adjust their corresponding photographic attributes simultaneously through a simple point-and-swipe interaction. To enable fast interaction, we develop a memory- and computation-efficient algorithm which samples a collection of 1D paths from the image, computes the adjustment solution along these paths, and interpolates the solutions to entire image through bilateral filtering. Our system is intuitive to use, and can support several local editing tasks, such as brightness, contrast, and color balance adjustments, within a minute on a mobile device.

However, most of the existing bilayer segmentation algorithms require either considerable user intervention or a simple stationary camera configuration with known background, which is difficult to meet for many real world online applications. This paper demonstrates that various visually appealing montage effects can be online created from a live video captured by a rotating camera, by accurately retrieving the camera state and segmenting out the dynamic foreground. The key contribution is that a novel fast bilayer segmentation method is proposed which can effectively extract the dynamic foreground under rotational camera configuration, and is robust to imperfect background estimation and complex background colors. Our system can create a variety of live visual effects, including but not limited to, realistic virtual object insertion, background substitution and blurring, non-photorealistic rendering and camouflage effect. A variety of challenging examples demonstrate the effectiveness of our method. [source] Volume and Isosurface Rendering with GPU-Accelerated Cell Projection,COMPUTER GRAPHICS FORUM, Issue 1 2008R. Marroquim Abstract We present an efficient Graphics Processing Unit GPU-based implementation of the Projected Tetrahedra (PT) algorithm. By reducing most of the CPU,GPU data transfer, the algorithm achieves interactive frame rates (up to 2.0 M Tets/s) on current graphics hardware. Since no topology information is stored, it requires substantially less memory than recent interactive ray casting approaches. The method uses a two-pass GPU approach with two fragment shaders. This work includes extended volume inspection capabilities by supporting interactive transfer function editing and isosurface highlighting using a Phong illumination model. [source] Differential Representations for Mesh ProcessingCOMPUTER GRAPHICS FORUM, Issue 4 2006Olga Sorkine Abstract Surface representation and processing is one of the key topics in computer graphics and geometric modeling, since it greatly affects the range of possible applications. In this paper we will present recent advances in geometry processing that are related to the Laplacian processing framework and differential representations. This framework is based on linear operators defined on polygonal meshes, and furnishes a variety of processing applications, such as shape approximation and compact representation, mesh editing, watermarking and morphing. The core of the framework is the definition of differential coordinates and new bases for efficient mesh geometry representation, based on the mesh Laplacian operator. [source] Interactive editing of digital fault modelsCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 12 2010Jordan Van Aalsburg Abstract We describe an application to interactively create and manipulate digital fault maps, either by tracing existing (paper) fault maps created from geological surveys, or by directly observing fault expressions and earthquake hypocenters in remote sensing data such as high-resolution (,100k × 100k elevation postings) digital elevation models with draped color imagery. Such fault maps serve as input data to finite-element-method simulations of fault interactions, and are crucial to understand regional tectonic processes causing earthquakes, and have tentatively been used to forecast future seismic events or to predict the shaking from likely future earthquakes. This fault editor is designed for immersive virtual reality environments such as CAVEs, and presents users with visualizations of scanned 2D fault maps and textured 3D terrain models, and a set of 3D editing tools to create or manipulate faults. We close with a case study performed by one of our geologist co-authors (Yikilmaz), which evaluates the use of our fault editor in creating a detailed digital fault model of the North Anatolian Fault in Turkey, one of the largest, seismically active strike-slip faults in the world. Yikilmaz, who was directly involved in program development, used our fault editor both in a CAVE and on a desktop computer, and compares it to the industry-standard software package ArcGIS.

[source] A Stitch in Time: Skills for the New LiteracyENGLISH IN EDUCATION, Issue 1 2000Cary Bazalgette Abstract This article examines the relationship between moving image study and English, with particular reference to understandings of the practice of editing. Starting from the premise that English teachers support the study of moving images in their subject, the article interrogates the kind of knowledge and understanding, and the range of skills which are implicated by editing. It ends by calling for a recasting of English in tune with the changes - and convergences - that new digital technologies are already heralding. [source] Peripheral B cell receptor editing may promote the production of high-affinity autoantibodies in CD22-deficient miceEUROPEAN JOURNAL OF IMMUNOLOGY, Issue 10 2006Yuval Yarkoni Abstract CD22-deficient mice are characterized by B cell hyperactivity and autoimmunity. We have constructed knock-in CD22,/, mice, expressing an anti-DNA heavy (H) chain (D42), alone or combined with V,1-J,1 or V,8-J,5 light (L) chains. The Ig-targeted mice produced a lupus-like serology that was age- and sex-dependent. High-affinity IgG autoantibodies were largely dependent on the selection of B cells with a particular H/L combination, in which a non-transgenic, endogenous L,chain was assembled by secondary rearrangements through the mechanism of receptor editing. Moreover, we present evidence that these secondary rearrangements are very prominent in splenic peripheral B cells. Since CD22 is primarily expressed on the surface of peripheral B cells, we propose a model for the development of a lupus-like autoimmune disease by a combination of peripheral receptor editing and abnormal B cell activation. [source] The tyrosine kinase Syk is required for light chain isotype exclusion but dispensable for the negative selection of B,cellsEUROPEAN JOURNAL OF IMMUNOLOGY, Issue 4 2004Josephine Meade Abstract In this study we set out to test whether Syk was required for negative selection of immature B,cells. B,cells expressing a B,cell antigen receptor (BCR) transgene (3,83, anti-H-2Kk) underwent negative selection independently of Syk in both fetal liver organ culture and radiation chimera models. Furthermore, Syk-independent negative selection was not reversed by transgenic overexpression of Bcl-2. Receptor editing was not apparent in Syk-deficient B,cells, presumably as a consequence of the failure of mature edited B,cells to develop in the absence of Syk. Interestingly, light chain isotype exclusion by the BCR transgene failed in the absence of Syk. We observed a dramatic reduction in the overall BCR-mediated tyrosine phosphorylation of cellular proteins in Syk-deficient immature B,cells. However, the tyrosine phosphorylation of a number of substrates including phospholipase,C,2, although reduced, was not completely abrogated. BCR ligation triggered an increase in calcium flux in the absence of Syk. Thus signaling events that mediate negative selection can still occur in the absence of Syk. This may be due to redundancy with zeta-associated protein,70 (ZAP-70), which we demonstrate to be expressed in immature B,cells. [source] COLLINGWOOD, BRADLEY, AND HISTORICAL KNOWLEDGEHISTORY AND THEORY, Issue 2 2006ROBERT M. BURNS ABSTRACT The central feature of the narrative structure of Collingwood's The Idea of History (IH) is the pivotal role accorded to Bradley, evident in the table of contents and in the two discussions of him. Few readers have noticed that, confusingly, the book's first discussion of Bradley (on pages 134-141) is a revision of the (1935) Inaugural Lecture "The Historical Imagination," which constitutes the book's second discussion of Bradley (on pages 231-249). The differences between these two presentations of Bradley are significant. The 1935 account (presented in IH on pages 231-249) seeks to portray the Bradley of the Presuppositions of Critical History as a Copernican revolutionary in historical thought, even though the neo-Kantian transcendentalism promoted in the Lecture had been the core of Collingwood's approach to philosophy of history from the mid-1920s, many years before he encountered Bradley's essay. By 1935 this transcendentalism was in the process of self-destructing because of inner contradictions. By 1936, once Collingwood's narrative and his criticisms of Bradley left the 1935 claims unsustainable, Collingwood shifted attention to Bradley's later works, in an unsuccessful attempt to sustain the notion of his originality (presented in IH on pages 134-141). Hitherto neglected Collingwood manuscripts held in the Bodleian prove that by 1940 Collingwood recognized this, so that the prominence Knox gave to Bradley in his editing of the IH is demonstrably not in accord with Collingwood's views and plans for The Idea of History. Knox's much-disputed claim that there was a radical shift to historicism in the later Collingwood is, however, confirmed, clear proof being adduced that in the later 1930s the attempt transcendentally to deduce universal and necessary presuppositions of historical knowledge is abandoned for a radically historicist account, paralleled by a demotion of "critical history" as the final form of "history proper" in favor of "scientific history." [source] Induction of 150-kDa adenosine deaminase that acts on RNA (ADAR)-1 gene expression in normal T lymphocytes by anti-CD3-, and anti-CD28IMMUNOLOGY, Issue 4 2007Dama Laxminarayana Summary We and other investigators have demonstrated up-regulation of the expression of the RNA-editing gene 150-kDa adenosine deaminase that acts on RNA (ADAR1) in systemic lupus erythematosus (SLE) T cells and B cells, peripheral blood mononuclear cells (PBMC), natural killer (NK) cells. The presence of a small proportion of activated T cells is the hallmark of SLE. Therefore, it was hypothesized that 150-kDa ADAR1 gene expression is induced by the physiological activation of T cells. To examine this hypothesis, normal T cells were activated by anti-CD3-, plus anti-CD28 for various time periods from 0 to 48 hr. The expression of 110-kDa and 150-kDa ADAR1, and interleukin (IL)-2 and ,-actin gene transcripts was analysed. An approximately fourfold increase in 150-kDa ADAR1 gene expression was observed in activated T cells. ADAR2 gene transcripts are substrates for ADAR1 and ADAR2 enzymes. Therefore, we assessed the role of the 150-kDa ADAR enzyme in editing of ADAR2 gene transcripts. In activated T cells, site-selective editing of the ,2 site was observed. Previous studies indicate that this site is predominantly edited by ADAR1. In addition to this, novel editing sites at base positions ,56, ,48, ,45, ,28, ,19, ,15, +46 and +69 were identified in activated T cells. On the basis of these results, it is proposed that 150-kDa ADAR1 gene expression is selectively induced in T cells by anti-CD3-, and anti-CD28 stimulation and that it may play a role in site-selective editing of gene transcripts and in altering the functions of several gene products of T cells during activation and proliferation. [source] Non-functional immunoglobulin G transcripts in a case of hyper-immunoglobulin M syndrome similar to type 4IMMUNOLOGY, Issue 2 2004John M. Darlow Summary 86% of immunoglobulin G (IgG) heavy-chain gene transcripts were found to be non-functional in the peripheral blood B cells of a patient initially diagnosed with common variable immunodeficiency, who later developed raised IgM, whereas no non-functionally rearranged transcripts were found in the cells of seven healthy control subjects. All the patient's IgM heavy-chain and , light-chain transcripts were functional, suggesting that either non-functional rearrangements were being selectively class-switched to IgG, or that receptor editing was rendering genes non-functional after class-switching. The functional ,-chain sequences showed a normal rate of somatic hypermutation while non-functional sequences contained few somatic mutations, suggesting that most came from cells that had no functional gene and therefore were not receiving signals for hypermutation. However, apoptosis of peripheral blood lymphocytes was not impaired. No defects have been found in any of the genes currently known to be responsible for hyper-IgM syndrome but the phenotype fits best to type 4. [source] Face modeling and editing with statistical local feature control modelsINTERNATIONAL JOURNAL OF IMAGING SYSTEMS AND TECHNOLOGY, Issue 6 2007Yu Zhang Abstract This article presents a novel method based on statistical facial feature control models for generating realistic controllable face models. The local feature control models are constructed based on the exemplar 3D face scans. We use a three-step model fitting approach for the 3D registration problem. Once we have a common surface representation for examples, we form feature shape spaces by applying a principal component analysis (PCA) to the data sets of facial feature shapes. We compute a set of anthropometric measurements to parameterize the exemplar shapes of each facial feature in a measurement space. Using PCA coefficients as a compact shape representation, we approach the shape synthesis problem by forming scattered data interpolation functions that are devoted to the generation of desired shape by taking the anthropometric parameters as input. The correspondence among all exemplar face textures is obtained by parameterizing a 3D generic mesh over a 2D image domain. The new feature texture with desired attributes is synthesized by interpolating the exemplar textures. With the exception of an initial tuning of feature point positions and assignment of texture attribute values, our method is fully automated. In the resulting system, users are assisted in automatically generating or editing a face model by controlling the high-level parameters. © 2008 Wiley Periodicals, Inc.
