Twistor Superstring in 2T-Physics
Creators: name: Bars, Itzhak

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: By utilizing the gauge symmetries of Two-Time Physics (2T-physics), a superstring with linearly realized global SU(2,2|4) supersymmetry in 4+2 dimensions (plus internal degrees of freedom) is constructed. It is shown that the dynamics of the Witten-Berkovits twistor superstring in 3+1 dimensions emerges as one of the many one time (1T) holographic pictures of the 4+2 dimensional string obtained via gauge fixing of the 2T gauge symmetries. In 2T-physics the twistor language can be transformed to usual spacetime language and vice-versa, off shell, as different gauge fixings of the same 2T string theory. Further holographic string pictures in 3+1 dimensions that are dual theories can also be derived. The 2T superstring is further generalized in the SU(4)=SO(6) sector of SU(2,2|4) by the addition of six bosonic dimensions, for a total of 10+2 dimensions. Excitations of the extra bosons produce a SU(2,2|4) current algebra spectrum that matches the classification of the high spin currents of N=4, d=4 super Yang Mills theory which are conserved in the weak coupling limit. This spectrum is interpreted as the extension of the SU(2,2|4 classification of the Kaluza-Klein towers of typeII-B supergravity compactified on AdS{5}xS(5), into the full string theory, and is speculated to have a covariant 10+2 origin in F-theory or S-theory. Further generalizations of the superstring theory to 3+2, 5+2 and 6+2 dimensions, based on the supergroups OSp(8|4), F(4), OSp(8*|4) respectively, and other cases, are also discussed. The OSp(8|4) case in 6+2 dimensions can be gauge fixed to 5+1 dimensions to provide a formulation of the special superconformal theory in six dimensions either in terms of ordinary spacetime or in terms of twistors.
description: 26 pages, LaTeX. In version 3, section 5, it is argued that the 6+2 2T-superstring with OSp(8*|4) supersymmetry provides a description of the special d=6 superconformal theory based on the tensor supermultiplet (not d=6 SYM as mentioned in version 2)

description: We consider light scattering by dielectric gratings supporting optical bound states in the continuum. Due to the presence of instantaneous Kerr nonlinearity the critical field enhancement in the spectral vicinity of the bound state triggers the effect of optical bistability. The onset of bistability is explained theoretically in the framework of the temporal coupled mode theory. As the central result we cast the problem into the form of a singly field-driven nonlinear oscillator. The theoretical results are verified in comparison against full-wave numerical simulations.

description: Recently, many countries ended the early 20th century-imposed sanctions on industrial hemp to invigorate the hemp-based economy. Following the revival, studies aimed at assessing the environment and economic sustainability of industrial hemp and products along (entire or certain) value chain nodes have become the priority of the research realm. Systematic assimilation of such studies may cater to comparison among diverse hemp-based products and their fossil-based counterparts. Therefore, the first objective of the current study was to conduct a systematic literature review aimed at evaluating the industrial hemp value chain from enviro-economic perspective. We searched databases, namely Science Direct, Scopus and Web of Science to retrieve articles on industrial hemp related to lifecycle assessment (LCA), value chain (VC) and financial feasibility components. The results of the literature search highlight hempcrete as an environmentally friendly product due to the carbon negativity. From the economic perspective, industrial hemp may not be viable for the entire value chain actors, however, addressing key intervention (such as harvesting and processing) nodes and capitalization of value addition and valorisation opportunities may foster promising future potential. Similarly, the second objective narrows the research gap in the global south (indicated by the review study) as it provides insights from Nepal where the hemp value chain may be legally contested. Using the case of Nepalese western mountain farmers and employing a mixed-method approach, we uncovered the tapestry of the illegal hemp value chain, evaluated the contribution of industrial hemp to pro-poor households, and analysed the structure, conduct, and performance of the industrial hemp value chain. Based on our findings, we conceptualized 'dark,' 'opaque,' and 'transparent' visions, which respectively illustrate the compassionate ground for production allowance, created opacity for outbound operations, and unconcealed distribution activities. Results suggest, albeit negative gross margin for hemp farmers, profit-making opportunities for downstream actors. Industrial hemp legalization, market integration, and consortium marketing are some of the identified strategies. Globally, the findings of this study have the potential to contribute to sustainability benchmarking of hemp-based products and encourage global collaboration in research and innovation. Nationally, it can guide policy intervention ii and the development of the integrated framework for greater industrial hemp value chain efficiency.
Partiti populisti, diritti e uguaglianza di genere

description: The Great Recession changed the political landscape of the European democracies with the electoral success of populist protest parties in different countries. In this article, we wonder if there are features that characterized these political parties about the issues of gender equality and women’s rights. Populism and feminization of politics are recurring topics in the scholars’ debate, but the relationships between these two phenomena are still little studied. Seeing as the issue is linked to context, and not only to the political parties’ differences, we will focus on three illustrative cases, in different European nations – Spain, Finland, Poland – analysing scientific literature and documents. The hypothesis is that the issues of gender can be an additional contentious line useful for defining identity and differences in the heterogeneous set of populist parties.

description: We study the $J/ψ$ photoproduction from nuclei in the near-threshold beam energy region of $E_γ$=5--11 GeV within the nuclear spectral function approach by considering incoherent direct ($γN \to {J/ψ}N$) and two-step ($γp \to P^+_c(4312)$, $P^+_c(4312) \to {J/ψ}p$; $γp \to P^+_c(4440)$, $P^+_c(4440) \to {J/ψ}p$; $γp \to P^+_c(4457)$, $P^+_c(4457) \to {J/ψ}p$) $J/ψ$ production processes. We calculate the absolute excitation functions for the non-resonant and resonant production of $J/ψ$ mesons off $^{12}$C and $^{208}$Pb target nuclei within the different scenarios for in-medium modification of the directly photoproduced $J/ψ$ mesons and for branching ratios of the decays $P^+_c(4312) \to {J/ψ}p$, $P^+_c(4440) \to {J/ψ}p$ and $P^+_c(4457) \to {J/ψ}p$. We show that the non-resonant subthreshold $J/ψ$ production in $γA$ reactions reveals some sensitivity to employed in-medium modification scenarios for $J/ψ$ mesons, which is not masked by the resonantly produced $J/ψ$ mesons, only if above branching ratios are less than 5\%. We also demonstrate that if these branching ratios more than 5\% then the presence of the $P^+_c(4312)$, $P^+_c(4440)$ and $P^+_c(4457)$ resonances in $J/ψ$ photoproduction on nuclei produces above threshold additional enhancements in the behavior of the total $J/ψ$ creation cross section on nuclei, which could be also studied in the future JLab experiments at the CEBAF facility to provide both further evidence for their existence and valuable information on their nature.

Partecipazione e genere in Europa: una questione di contesto?

description: This study proposes an analysis on the theme of gender differences with respect to participation in political and social life. Specifically, it takes into account the findings of traditional, revisionist and radical studies, proposing an updated and gender sensitive interpretation. In this way, we can distinguish between cause, civic and campaign oriented forms of participation, selecting among the different types and classifications proposed by studies oriented to the analysis of female involvement. The hypotheses proposed refer to the possible effects of the availability of resources (time, money, education), socialization (children, marriage, religion, divorce), motivations (trust, self-direction, information) and values (materialist, solidal, liberalist ethics). Moreover, the dynamics linked to opportunities and contextual constraints are kept under control, specifically linked to welfare policies and availability of resources to guarantee equity. A further hypothesis concerns effects that discriminate not only with respect to gender but also with reference to the mechanisms of mobilization. The analyses, carried out with data from the wave 2018 of the European Social Survey, demonstrate the substantial validity of the hypotheses and, in particular, differences emerge with respect to the type of participation and strong impact of contextual dynamics. Finally, partial confirmations of differences in mobilisation mechanisms with respect to gender emerge.

description: (Abridged) We have obtained HST WFPC2 observations of three very luminous but morphologically different giant HII regions (GHRs) in M101, NGC5461, NGC5462, and NGC5471, in order to study cluster formation in GHRs. The measured (M_F547M - M_F675W) colors and M_F547M magnitudes are used to determine the ages and masses of the cluster candidates with M_F547M <= -9.0. NGC5461 is dominated by a very luminous core, and has been suggested to host a super-star cluster (SSC). Our observations show that it contains three R136-class clusters superposed on a bright stellar background in a small region. This tight group of clusters may dynamically evolve into an SSC in the future, and may appear unresolved and be identified as an SSC at large distances, but at present NGC5461 has no SSCs. NGC5462 has loosely distributed HII regions and clusters without a prominent core. It has the largest number of cluster candidates among the three GHRs, but most of them are faint and older than 10 Myr. NGC5471 has multiple bright HII regions, and contains a large number of faint clusters younger than 5 Myr. Two of the clusters in NGC5471 are older than R136, but just as luminous; they may be the most massive clusters in the three GHRs. The fraction of stars formed in massive clusters is estimated from the clusters' contribution to the total stellar continuum emission and a comparison of the ionizing power of the clusters to the ionizing requirement of the associated HII regions. Both estimates show that

description: This paper examines the relations of trust in agricultural cooperation from two aspects. On the one hand, it gives a short review of relevant literature, with special regard to agri-food economy. On the other hand, it uses the results of empirical survey for the analysis of trust in machinery sharing arrangements of Hungarian agricultural producers. In connection with this, the trust is examined in two dimensions: contractual and competence trust. Our results prove that there is a positive correlation between the level of trust and the farmers’ activity in cooperative agreements. It could also be proved that the trust need is very different in the different fields of cooperation. It is a tendency that the contractual trust is more important in more intensive, higher-dependence cooperation activities, while competence trust becomes into the foreground in the more extensive solutions.

description: Electron spin coherence is induced via light-hole transitions in a quantum well waveguide without either an external or internal DC magnetic field. In the absence of spin precession, the induced spin coherence is detected through effects of quantum interference in the spectral domain coherent nonlinear optical response. We interpret the experimental results qualitatively using a simple few-level model with only the optical transition selection rule as its basic ingredients.
N-Impurity Superstring Spectra Near the pp-Wave Limit

description: The complicated non-linear sigma model that characterizes the first finite-radius curvature correction to the pp-wave limit of IIB superstring theory on AdS_5 x S^5 has been shown to generate energy spectra that perfectly match, to two loops in the modified 't Hooft parameter lambda', finite R-charge corrections to anomalous dimension spectra of large-R N=4 super Yang-Mills theory in the planar limit. This test of the AdS/CFT correspondence has been carried out for the specific cases of two and three string excitations, which are dual to gauge theory R-charge impurities. We generalize this analysis on the string side by directly computing string energy eigenvalues in certain protected sectors of the theory for an arbitrary number of worldsheet excitations with arbitrary mode-number assignments. While our results match all existing gauge theory predictions to two-loop order in lambda', we again observe a mismatch at three loops between string and gauge theory. We find remarkable agreement to all loops in lambda', however, with the near pp-wave limit of a recently proposed Bethe ansatz for the quantized string Hamiltonian in the su(2) sector. Based on earlier two- and three-impurity results, we also infer the full multiplet decomposition of the N-impurity superstring theory with distinct mode excitations to two loops in lambda'.

description: Because serial correlation in linear panel-data models biases the standard errors and causes the results to be less efficient, researchers need to identify serial correlation in the idiosyncratic error term in a panel-data model. A new test for serial correlation in random- or fixed-effects one-way models derived by Wooldridge (2002) is attractive because it can be applied under general conditions and is easy to implement. This paper presents simulation evidence that the new Wooldridge test has good size and power properties in reasonably sized samples.

Quale genere di astensionismo? La partecipazione elettorale delle donne in Italia nel periodo 1948-2018

description: In the study of voter turnout, a gender perspective is useful in many ways. Since in Italy women gained the right to vote relatively late (only in 1946), a gender gap perspective is utmost handy to grasp why women had an immediate and massive participation over the First Republic. It is also relevant for understanding why their institutional representation comparatively still scores low and why women still do not bear a grounded interest for politics. Previous research explains this anomalous behaviour (high turnout coupled with low institutional presence and interest) through the overwhelming social conformism in the Fifties and Sixties as an output of a stark contrast between mass parties, Catholic influence and deep social peer pressure. In the Second Republic, the explanation for the rise of female abstention is related to both the secularization of social and family behaviours and a general disaffection towards politics. This article outlines a long-term read of gender gap in the political turnout (1948-2018) through the aid of two sections (one pointing out the initial characteristics for a strong mobilization of female voters and another pinpointing the reverse phenomenon in the last 30 years). We then offer some points for discussion about attributed meanings, working from within inequalities and possible future effective policies to contain and reduce the gender gap in political turnout.

description: Bone is a stiff, porous, hierarchical structure living tissue that provides structural support to the body via the skeletal system. Bone structural integrity is crucial for the quality of life. However, bones can only bear a load until a certain limit, without experiencing permanent deformation or failure. Therefore, investigation of fracture behaviour of weight-bearing bones of the lower limbs such as femur is of great interest. Additionally, due to the anatomical location and geometry of femur neck, it is the most common fractured location of femur bone particularly in the older adults and patients who have musculoskeletal disorders that often cause to permanent disability or mortality. On the other hand, the mechanical and microstructural properties of cortical bone of femur neck are not adequately understood. This originates from limitations in specimen size for mechanical testing. Therefore, the size of the specimen is an essential matter in mechanical bone behaviour studies. Hence, this thesis aim to investigate the size limitation for maintaining the material continuum assumption. This aim can be accomplished by examining the structural and mechanical properties of cortical bone such as fracture toughness which explains the resistance of bone to crack beginning and propagation. In this thesis, fracture behaviour of cortical bone was studied under three-point bending test which was conducted on single-edge-notch bending (SENB) specimens with different size, 1 mm x 1 mm, 1.7 mm x 1.7 mm, and 3 mm x 3 mm, by the transverse notched direction from different cortex positions, called anterior, lateral, medial, and posterior, from mid-shaft of two equine femurs with different ages. Due to anisotropic behaviour and hierarchical structure of cortical bone, in this thesis, elastic plastic fracture mechanics approach is the best method to evaluate the fracture toughness and fracture energy of cortical bone that was conducted using J-integral approach. Fracture toughness of both equine cortical bone was found to be sensitive to beam size particularly in the young femur. However, most of the significant differences of fracture energy in the largest beam size still present in the smallest beam size with the lower detectability differences except for one case. Therefore, it should be feasible to use fracture energy for smaller samples where it is not possible to obtain larger samples.

description: The spatial distribution of agro-environmental policy benefits has important implications for the efficient allocation of management effort. The practical convenience of relying on sample mean values of individual benefits for aggregation can come at the cost of biased aggregate estimates. The main objective of this paper is to test spatial hypotheses regarding respondents’ local water quality and quantity, and their willingness-to-pay for improvements in water quality attributes. This paper combines choice experiment and spatially related water quality data via a Geographical Information System (GIS) to develop a method that evaluates the influence of respondents’ local water quality on willingness-to-pay for river and stream conservation programs in Canterbury, New Zealand. Results show that those respondents who live in the vicinity of low quality waterway are willing to pay more for improvements relative to those who live near to high quality waterways.
Assessment of collaborative decision-making in design development and coordination meetings
Creators: name: Golparvar Fard, Mani
Publisher: name: University of British Columbia
Year: 2010

description: Building design is a complex multi-disciplinary process that requires extensive collaboration to develop a coordinated design that satisfies the functional, aesthetic, and economic requirements of the owner. Today, design meetings typically take place in physical workspaces, such as conference rooms, where all the relevant members of the team work together in the same place and time. Although most project information is generated electronically, teams primarily communicate and share information using paper-based representations. Emerging technologies such as touch-sensitive large-screen displays, table-top displays, laptops, and tablet PCs offer great promise in enriching today’s paper-based workspaces to create what are known as interactive workspaces. 3D design tools are also gaining acceptance and providing significant benefits to the design coordination process. However, it remains unclear as to how such tools and technologies can be incorporated effectively in workspaces to support design coordination meetings. This research addresses this need by characterizing how people spend time performing collaborative decision-making tasks in design development meetings. I conducted a five-month field study of the design development process for the Centre for Interactive Research on Sustainability (CIRS) project being constructed near downtown Vancouver, British Columbia. I observed weekly design development meetings and performed a thorough post-meeting video analysis. During the meetings, I took detailed notes documenting the meeting activities, the kind of information sources and representations used, and the interactions meeting participants had with information. The video was analyzed to identify how time is spent on different decision-making tasks and to determine the effectiveness of those tasks. This research found that the majority of time in design development meetings is spent on descriptive (35%) and explanative (42%)a sks and very little time is spent on evaluative (12%)n d predictive (11%) tasks. However, resolution rates- percentage of tasks resolved- were still quite high in these meetings. with an average of 73%. Based on the analysis, paper-based meetings were compared and an initial set of requirements for accomplishing design development tasks in a computer-supported interactive workspace were identified. In summary, successful interactive workspaces should support physical as well as digital artefacts, digital records of meetings, and digital overlays of schematic diagrams.

Conflict detection in 3D MEP coordination : tools, constraints and cost
Creators: name: Subramanian, Ganesh
Publisher: name: University of British Columbia
Year: 2010

description: Coordination is an integral part of many activities during the life of a construction project. Traditionally, building systems are parts of the buildings that temper the building environment, distribute energy, allow for communication, enable critical manufacturing process, and provide and dispose water. With increases in the functionality and complexity of buildings, projects now include much more than just the traditional Mechanical, Electrical, and Plumbing (MEP) systems. The MEP scope now includes additional systems such as fire protection, controls, process piping, and telephone / datacom. Building system coordination involves the detailed layout and configuration of the various building systems such that it complies with design, construction, and operations criteria. Specialty contractors are typically responsible for the coordination of MEP systems, including checking clearances and identifying routes, fabrication details, and installation locations. The current MEP coordination process used in the industry is highly fragmented between design and construction firms, the level of technology used in different coordination scenarios varies significantly and does not provide a facility model for use over the complete life cycle. The main objective of this thesis is elaborate on the role of constraint-based design in MEP coordination process in conjunction with checking for constraint-based conflicts using the state-of- the-art tool, NavisWorks JetStream (NavisWorks). To achieve this objective the 3D Models of the MEP Systems of University of British Columbia’s (UBC) Chemical and Biological Engineering Building have been analyzed for the constraint-based conflicts and the constraints governing the MEP systems have been classified based on the resulting type of conflict they generate. Also, a quantification of MEP coordination costs sustained in the project and the cost and productivity benefits resulting by implementing 3D MEP coordination for the project have been discussed. The Thesis concludes that using NavisWorks for conflict detection and management does enhance the knowledge on the constraint-based conflicts (e.g. clearance related constraints) in comparison to Autodesk® Building Systems (ABS). The classification of the constraints based on the resulting type of conflicts helps the project participants to have an idea on which constraints have to be given more importance while designing the MEP systems. From the study on the MEP coordination costs and the effect of field generated conflicts on these costs and project productivity, this thesis concludes that the investments in coordination typically pay for themselves by reducing conflicts and field generated change order costs in MEP intensive projects.

In particular, a closed algebraic formula for the edge of regression of the surface is obtained in terms of the functions $Λ$, $M$, $ν$, which are closely related to the ones that appear in the standard decomposition of the derivative of the parametrisation of one of the bounding curves in terms of the director vector of the rulings and its derivative. It is also shown that all rational developable surfaces can be described as the set of developable surfaces which can be constructed with a constant $Λ$, $M$, $ν$ . The results are readily extended to rational spline developable surfaces.

description: This paper presents an introduction to the astrophysics of cosmic rays and diffuse gamma rays and discusses some of the puzzles that have emerged recently due to more precise data and improved propagation models: the excesses in Galactic diffuse gamma-ray emission, secondary antiprotons and positrons, and the flatter than expected gradient of cosmic rays in the Galaxy. These also involve the dark matter, a challenge to modern physics, through its indirect searches in cosmic rays. Though the final solutions are yet to be found, I discuss some ideas and results obtained mostly with the numerical propagation model GALPROP. A fleet of spacecraft and balloon experiments targeting these specific issues is set to lift off in a few years, imparting a feeling of optimism that a new era of exciting discoveries is just around the corner. A complete and comprehensive discussion of all the recent results is not attempted here due to the space limitations.

Charm elliptic flow from quark coalescence dynamics
Creators: name: Molnar, Denes
Publisher: name: arXiv
Year: 2004
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: From covariant transport theory, a significant ~10% light quark elliptic flow at RHIC implies an elliptic flow of similar magnitude for charm quarks, at moderately large pT > 2.5 - 3 GeV. At lower transverse momenta, charm quark elliptic flow reduces progressively, reminiscent of the mass ordering pattern in ideal hydrodynamics. From the quark flows we predict the elliptic flow of D mesons at RHIC via quark coalescence. The large parton opacities needed to generate the light quark flow also lead to substantial ~40-50% secondary charm production.

description: Tanulmányunkban az ökoélelmiszerek fogyasztói megítélését, a fogyasztói szokásokat és azokat befolyásoló tényezőket mutatjuk be. Az 1200 fős primer megkérdezés eredményei szerint a fogyasztók az ökoélelmiszerekről egyre bővebb ismeretekkel rendelkeznek, felismerik és keresik őket. A vegyszermentességük és természetességük miatt ezeket a termékeket az egészségre kedvező hatásúnak tartják. A magas ár azonban még mindig korlátot jelent, az értékarányos ár elfogadásához több tájékoztatás és erőteljesebb kommunikáció szükséges. Az ökotermékek értékesítésekor rendkívül fontos a bizalom, amely egyrészt az eladó és a vevő közvetlen kapcsolatának erősítésével, másrészt a minősítési rendszer szigorúságával garantálható. --------------------------------------- In our study we present consumers’ perception of organic food, consumer habits and the factors affecting them. Based on a survey of 1200 people, the results show us that con sumers have extensive information on organic food; they recognize such food and active ly seek it out. The absence of added chemicals in organic foods leads people to assume these products have a good effect on health. However, the high price of such foods is still a limiting factor. Stronger communication is necessary for consumers to accept a proportionate price. Reliability is very important in selling an organic food product. The authentically or ganic nature of a product can be guaranteed by strengthening the relationship of consum ers and vendors on one hand and through strict qualification systems on the other hand.

description: A magyar hűtőipar számára a külföldi piacokon való értékesítés nagy jelentőségű. A hűtőipar talán az egyetlen ágazat, melynek termelése minőségileg sosem különült el az értékesítés piacai szerint, köszönhetően annak, hogy a vertikumban a nemzetközi követelmények érvényesültek. A komplex vásárlói modellek elemzését követően megállapítható, hogy az ízesített termékeket leginkább az aktív szellemi foglalkozásúak részesítik előnyben, akik átlag feletti jövedelemmel rendelkeznek. Az ízesített termékek és a vegyes összetevőjű (mix) termékek tipikus vásárlója között nem tapasztalható jelentős eltérés. A vizsgálat eredményei alapján az a következtetés vonható le, hogy az egy összetevőjű termékek vásárlói között a legalacsonyabb a férfiak és a legmagasabb a nők, valamint a középfokú végzettségűek aránya. --------------------------------------------- The marketing of products in foreign markets is of paramount importance for the Hungarian deep freeze industry. The deep freeze industry may be the only sector where the quality of products has never varied according to the target market, as the product chain is ruled by international requirements. The analysis of complex customer models leads us to conclude that flavoured products were favoured by mostly persons of white collar vocations, who have an above average in come. No significant discrepancies were perceived between the typical customers of flavoured products and products of mixed ingredients. Based on the results of the analysis it can be stated that among the customers choosing products consisting of one component only, the ratio of men was lowest whereas that of women and persons having secondary education was highest.

description: Hazánkban az utóbbi években egyre nagyobb területeken folyik alkaloida és étkezési mák termelése. Megállapítható, hogy nem igazolódtak be azok a várakozások, melyek az uniós csatlakozástól a máktermelés csökkenését várták, annak ellenére, hogy az unió korlátozta egyes hazai, magasabb alkaloidatartalmú fajták termelését. Vizsgálataink alapján megállapítható, hogy a máktermelés magas hektáronkénti termelési költsége ellenére jövedelmező. Ha a hazai máktermelést az 1960-as évek szintjére emelnék, akkor az hozzájárulhatna a napjainkban fennmaradásukért és mindennapi megélhetésükért küzdő – elsősorban a szegényebb kelet-magyarországi régiókban – gazdálkodók megélhetéséhez. ------------------------------------- The area used for growing poppy seed for human consumption or alkaloid production in Hungary has been growing in recent years. We can conclude that the fears that Hunga ry’s accession to the European Union would reduce poppy seed growing did not come true even though the Community limited the growing of certain Hungarian varieties with a higher alkaloid concentration. Our research shows that despite its high per-hectare cost, poppy seed growing is a profitable activity. If we could increase poppy seed growing in Hungary to the level where it was in the 1960-ies, it could contribute to the livelihood of farmers - especially in the poorer areas of Eastern Hungary – who are currently fighting to make ends meet and survive.

description: We present a nonparametric statistical framework for the quantification, analysis, and propagation of data uncertainty in direct volume rendering (DVR). The state-of-the-art statistical DVR framework allows for preserving the transfer function (TF) of the ground truth function when visualizing uncertain data; however, the existing framework is restricted to parametric models of uncertainty. In this paper, we address the limitations of the existing DVR framework by extending the DVR framework for nonparametric distributions. We exploit the quantile interpolation technique to derive probability distributions representing uncertainty in viewing-ray sample intensities in closed form, which allows for accurate and efficient computation. We evaluate our proposed nonparametric statistical models through qualitative and quantitative comparisons with the mean-field and parametric statistical models, such as uniform and Gaussian, as well as Gaussian mixtures. In addition, we present an extension of the state-of-the-art rendering parametric framework to 2D TFs for improved DVR classifications. We show the applicability of our uncertainty quantification framework to ensemble, downsampled, and bivariate versions of scalar field datasets.
