description: We present preliminary results for the contributions to the neutron EDM arising from the QCD $θ$-term, the Weinberg three-gluon and the quark chromo-EDM operators from our ongoing lattice calculations using clover valence quarks on the MILC HISQ lattices. We use the gradient-flow technique to smooth the lattices and renormalize the gluonic operators, and use the Schwinger source method to incorporate the quark chromo-EDM interactions in the quark propagator. For the QCD $θ$-term and the Weinberg three-gluon operator, we report results in the gradient-flow scheme from 8 ensembles at four lattice spacings and three pion masses, including 2 physical pion mass ensembles. For the quark chromo-EDM, unrenormalized results are presented at two lattice spacings, $a=0.12$ and $0.09$ fm, and two pion masses, $M_π= 310$ MeV and $220$ MeV.

Mira science with interferometry: a review
Creators: name: Scholz, Michael
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Model-predicted and observed properties of the brightness distribution on M-type Mira disks are discussed. Fundamental issues of limb-darkening and diameter definition, of assigning observational data to diameter-type quantities and of interpreting such quantities in terms of model diameters are outlined. The influence of model properties upon interpretation of measured data is clarified. The dependence of the centre-to-limb variation (CLV) of intensity on wavelength, on stellar parameters and on variablity phase and cycle may be used for analyzing the geometrical and physical structure of the Mira atmosphere, for determining fundamental stellar parameters, and for investigating the quality of models. Desirable future observations include simultaneous observations in different spectral features at different phases and cycles, observation of the position of the shock front and observation of the time- and wavelength-dependence of deviations from spherical symmetry.

description: The availability of technology plays a major role in the feasibility and costs of climate policy. Nonetheless, technological change is highly uncertain and capital intensive, requiring risky efforts in research and development of clean energy technologies. In this paper, we introduce a two-track method that makes it possible to maintain the rich set of information produced by climate-economy models while introducing the dimension of uncertainty in innovation ef- forts, without succumbing to computation complexity. In particular, we solve the problem of an optimal R&D portfolio by employing Approximate Dynamic Programming, through multiple runs of an integrated assessment model (IAM) for the purpose of computing the value function, and expert elicitation data to quantify the relevant uncertainties. We exemplify the methodology with the problem of evaluating optimal near-term innovation investment portfolios in four key clean energy technologies (solar, biofuels, bioelectricity and personal electric vehicle batteries), taking into account the uncertainty surrounding the effectiveness of innovation to improve the performance of these technologies. We employ an IAM (WITCH) which has a fairly rich description of the energy technologies and experts’ beliefs on future costs for the above-mentioned technologies. Focusing on Europe and its short-term climate policy commitments, we find that batteries in personal transportation dominate the optimal public R&D portfolio. The resulting ranking across technologies is robust to changes in risk-aversion, R&D budget limitation and assump- tions on crowding out of other investments. These results suggest an important upscaling of R&D efforts compared to the recent past.

description: The effect of repeatedly smearing SU(3) gauge configurations is investigated. Six gauge actions (Wilson, Symanzik, Iwasaki, DBW2, Beinlich-Karsch-Laermann, Langfeld; combined with a direct SU(3)-overrelaxation step) and three smearings (APE, HYP, EXP) are compared. The impact on large Wilson loops is monitored, confirming the signal-to-noise prediction by Lepage. The fat-link definition of the ``naive'' topological charge proves most useful on improved action ensembles.

description: The paper is largely based on the main findings of the research on the state of the utilisation of the labour force in Italy, carried out by a group of economists at the Faculty of Economics and the ISTAO of Ancona, from 1974 to 1978. The study analysed the Italian economy’s lagged level of development by making international comparisons of the structure of productive capacity and income distribution, and their relations with the labour market. In this regard, the structural imbalances of the productive system and the dualism in the labour market between the regular and irregular employment sectors were highlighted. The author provides an overall view of the most important empirical conclusions of the study. JEL: E23, E24

description: In the recent work of Nakariakov et al. (2004), it has been shown that the time dependences of density and velocity in a flaring loop contain pronounced quasi-harmonic oscillations associated with the 2nd harmonic of a standing slow magnetoacoustic wave. That model used a symmetric heating function (heat deposition was strictly at the apex). This left outstanding questions: A) is the generation of the 2nd harmonic a consequence of the fact that the heating function was symmetric? B) Would the generation of these oscillations occur if we break symmetry? C) What is the spectrum of these oscillations? Is it consistent with a 2nd spatial harmonic? The present work (and partly Tsiklauri et al. (2004b)) attempts to answer these important outstanding questions. Namely, we investigate the physical nature of these oscillations in greater detail: we study their spectrum (using periodogram technique) and how heat positioning affects the mode excitation. We found that excitation of such oscillations is practically independent of location of the heat deposition in the loop. Because of the change of the background temperature and density, the phase shift between the density and velocity perturbations is not exactly a quarter of the period, it varies along the loop and is time dependent, especially in the case of one footpoint (asymmetric) heating. We also were able to model successfully SUMER oscillations observed in hot coronal loops.

description: The paper examines the relationship between monetarism and ideology, as well as non-monetarism and ideology. The identification of two coexisting strands of the 1930s Chicago monetarism, distinguished in terms of business-cycle theory and stabilisation policy, provides the basis for the suggestion that monetarism is not the exclusive domain of conservatism. Furthermore, the delineation of the ideological battle during the 1930s and 1940s between Chicago monetarists Frank Knight and Henry Simons, on the one hand, and Paul Douglas, on the other, highlights the subsequent emergence of Chicago monetarism in association with right-wing ideology.

description: Exceptional orthogonal polynomials are families of orthogonal polynomials that arise as solutions of Sturm-Liouville eigenvalue problems. They generalize the classical families of Hermite, Laguerre, and Jacobi polynomials by allowing for polynomial sequences that miss a finite number of "exceptional" degrees. In this paper we introduce a new construction of multi-parameter exceptional Legendre polynomials by considering the isospectral deformation of the classical Legendre operator. Using confluent Darboux transformations and a technique from inverse scattering theory, we obtain a fully explicit description of the operators and polynomials in question. The main novelty of the paper is the novel construction that allows for exceptional polynomial families with an arbitrary number of real parameters.
Indicatori aggregati e settoriali della politica monetaria (Sectoral and aggregate indicators of monetary policy)

description: The recent debate on the management of monetary policy in Italy has paced attention on the problems of the meaning and use of synthetic indicators of monetary conditions. The present work seeks to clarify the logical relationships between the real "indicators" of monetary policy and other monetary magnitudes within the framework of the usual frame of reference instruments-goals intermediate-goals. On the basis of this analysis the authors examine the characteristics and significance of some aggregate monetary indicators currently used in Italy. Particular emphasis is placed on the cognitive limits of the aggregate indicators, which offer the notable advantage of synthetic and timely information, but if "read" in isolation, can sometimes lead to error. They then propose integrating the economic analysis based on aggregate indicators with the systematic use of sectoral indicators derived from the Financial Accounts of the Bank of Italy .

description: In this brief note the author comments on Carlo D’Adda’s Greater precision regarding “crowding out”, offering three additional observations on the topic. While it is true that the concept was used largely in ideological terms in Italy, it resulted in the widespread belief that an increase in spending and the public debt was simultaneously the cause and effect of the weakening of the productive structure - in the way in which it alternately depended on a reduction in the propensity to spend in the private sector or on a restrictive monetary policy. Even if imprecise, this diagnosis does not seem to be far from reality. JEL: E51, H63, E52

description: The Common Agricultural Policy (CAP), one of the main forces working for the integration of EEC member countries, generates an economic burden for each member which affects the balance of payments and the real income. This study assesses, for each member country, consumers’ transfers to the farmers of the other member countries, and calculates by how much imported and exported food prices are higher. The author establishes the net cost or benefit of the CAP to the balance of payments of each member country, i.e. the loss or gain of foreign exchange reserves. For simplicity, the methodology adopted assumes that there is no downward impact of the CAP on extra-EEC agricultural prices, which in its absence, would be higher. Results for each member countries are, therefore, not valid per se but in comparison with the results of the other member countries. Final results show that Italy bears the heaviest share of the burden. JEL: F31, F32, F36

description: In recent years several European municipalities have paired market-based measures with urban distribution centres (UDC) in order to reduce CO2 emissions and make more sustainable urban freight ‡ows. However, UDCs may add reloading costs and extra delivery times which have relevant impact on both urban supply chains and the competition among traditional and UDC-based logistics service providers in terms of service quality and freight rates. By using a duopolistic Hotelling framework, we show that market-based measures and subsidies might be substitutes to enhance the demand for UDC-based providers but public funding can be reduced by improving the quality of UDC services. These results can enlarge the scope for investments in UDC value-adding services in order to decrease private crowding-out effects in the long run.

RNA secondary structure prediction using hierarchical folding
Creators: name: Hosna, Hosna
Publisher: name: University of British Columbia
Year: 2011

description: Algorithms for prediction of RNA secondary structure— the set of base pairs that form when an RNA molecule folds— are valuable to biologists who aim to understand RNA structure and function. Improving the accuracy and efficiency of prediction methods'is an ongoing challenge, particularly for pseudoknotted secondary structures, in which base pairs overlap. This challenge is biologically important, since pseudoknotted structures play essential roles in functions of many RNA molecules, such as splicing and ribosomal frameshifting. State-of-the- art methods, which are based on free energy minimization, have high runtime complexity (typically θ(n⁵) or worse), and can handle (minimize over) only limited types of pseudoknotted structures. We analyze a new approach for prediction of pseudoknotted structures, motivated by the hypothesis that RNA structures fold hierarchically, with pseudoknot free (non-overlapping) base pairs forming first, and pseudoknots forming later so as to minimize energy relative to the folded pseudoknot free structure. Our HFold algorithm, based on work of S. Zhao, uses two-phase energy minimization to predict hierarchically-formed secondary structures in 0(n³) time, matching the complexity of the best algorithms for pseudoknot free secondary structure prediction via energy minimization. Our algorithm can handle a wide range of biological structures, including kissing hairpins and nested kissing hairpins, which have previously required θ(n⁶) time. We also report on the experimental evaluations of HFold and present thorough analyses of the results. We show that if the input structure to the algorithm is correct, running the algorithm results in 16% accuracy improvement on average over the accuracy of the true pseudoknot free structures. However if the input structure is not correct, the accuracy improvement is not significant. If the first 10 suboptimal foldings are given as input to our algorithm instead of just the minimum free energy structure (MFE), the prediction accuracy improves significantly over the accuracy of the MFE structures. This improvement is even more when the number of suboptimal foldings as input to our algorithm increases. The comparison of the energy of the structures predicted by HFold on the true pseudoknot free structures with the energy of the true structures calculated using a different method with the same energy model shows that the energy model may be the cause for the cases for which HFold predicts structures far from the true structures. Our experimental result provides some ways in which the hierarchical folding hypothesis might need to be refined.

Building on the library, we have also implemented a detection pipeline accessible both as a desktop program (ViaNearby) and via a web server (Webrella), which we have successfully used in near real-time data reduction of a few asteroid surveys on the Wide Field Camera of the Isaac Newton Telescope. In this paper we describe the library, focusing on the interfaces and algorithms available, and we present the results obtained with the desktop version on a set of well-curated fields used by the EURONEAR project as an asteroid detection benchmark.

description: Since the Second World War, monetary policy in Italy has taken on a fundamental role in the control of the production cycle, the balance daily payments and prices. The present study analyzes the reasons for and effects of monetary policy over the last decade, when destabilizing impulses, both internal and external, became more frequent and intense and as a result required numerous interventions. The author also considers the stabilization policies of 1947-48 as well as those of the sixties, the control of interest rates and the evolution of monetary aggregates during the periods of development of the fifties and sixties, highlighting the similarities and differences in the instruments and performance with respect to the actions taken in the most recent period. The description is implemented in chronological order, situating the analysis of monetary policy actions in the context of economic developments, and in relation to other economic policy measures.

description: The work is concerned with the relationship between the monetary base and the quantity of money in Italy. The objective is not to develop a detailed description of the monetary base for Italy, but rather to explain in simple terms how the monetary base is related to bank deposits and money, and how changes in required reserve ratios have an impact on deposit determination in an equivalent way to changes in the monetary base that result from purchases of securities or foreign exchange by the monetary authorities. Building on this exposition, the paper shows that the method that the Bank of Italy uses to adjust the monetary base for required reserve ratio changes is incorrect. JEL: E51, E58

Compressible subsonic flow on a staggered grid

Publisher: name: University of British Columbia
Year: 2011

description: This work focuses on numerically modelling the dynamics of a single phase fluid at varying densities and pressures. We explore the potential of incompressible flow simulation methods in modelling compressible flow, with an eye towards computer animation applications. The methods developed capture the interesting thermodynamic effects of compressible flow, and reduce to the standard Marker and Cell incompressible flow Poisson matrix in the incompressible limit. The method works well in modelling flows in the subsonic range that normal incompressible techniques do not capture and where compressible methods are inefficient. We have also investigated adapting these techniques to granular elastic-plastic flow.

description: Following the first oil crisis, France launched the world’s largest ever nuclear energy program, commissioning 58 new reactors. These reactors are now reaching 40 years of age, the end of their technological lifetime. This places France at an energy policy crossroads: should the reactors be retrofitted or should they be decommissioned? The cost-optimal decision depends on several factors going forward, in particular the expected costs of nuclear energy production, electricity demand levels and carbon prices, all of which are subject to significant uncertainty. To deal with these uncertainties, we apply the Robust Decision Making framework to determine which reactors should be retrofitted. We build an investment and dispatch optimization model, calibrated for France. Then we use it to study 27 retrofit strategies for all combinations of uncertain parameters, which amounts to nearly 3,000 runs. Our analysis produces two robust strategies, which involve shutting down between 7 and 14 of the 14 oldest reactors, while extending the lifetime of all remaining reactors. These strategies provide a hedge against the risks of unexpected increases in retrofit costs, low demand and low carbon price. Our robust strategies differ from the official French government scenarios on the timing and number of reactors suggested to be decommissioned. They provide a timely contribution to the current debate on the extension of lifetime of nuclear plants in France.

description: Over the course of the Seventies, the determination of the cost of labor per unit of output () has become increasingly important, not only as a key element in the analysis of the evolution of competitiveness, but also as a key to understanding and interpreting certain structural aspects. The conclusions of some comparative studies on the cost of labour have linked the evolution of the internal economic system as a whole with its position in the international economy. However, they have suffered from obvious and significant limitations since, referring to the average of very different sectoral situations, they do not consider the specific imbalances which call for structural economic policy interventions. The present study, based on the initial results of a research by sector and business units conducted by the Commission of the EEC, aims to contribute to overcoming these limitations with a comparative analysis of some of the most significant sectors of the Italian economy.

description: Model differences in technological and geographical scales are common, but their contributions to uncertainties have not been systematically quantified in the climate policy literature. This paper carries out a systematic assessment on the sensitivity of Computable General Equilibrium models to technological and geographical scales in evaluating the economic impacts of carbon mitigation policies. Taking Italy as an example, we find that the estimation for carbon price and the economic cost of a de-carbonization pathway by means of a model with technological and regional details can be lower than a model without such details by up to 40%. Additionally, the effect of representing regional details appears to be far more important than the effect of representing the details of electricity technology in both the estimated carbon prices and the estimated economic impacts. Our results for Italy highlight the importance of modeling uncertainties of these two key assumptions, which should be appropriately acknowledged when applying CGE models for policy impact assessment. Our conclusions can be generalized to different countries and policy scenarios not in terms of absolute numbers but in terms of economic explanations. In particular, intra-national trade and the sub-national sectoral/technological specialization are important variables for understanding the economic dynamics behind these outcomes.
Local Simulations of Heating Torques on a Luminous Body in an Accretion Disk

description: A luminous body embedded in an accretion disk can generate asymmetric density perturbations that lead to a net torque and thus orbital migration of the body. Linear theory has shown that this heating torque gives rise to a migration term linear in the body's mass that can oppose or even reverse that arising from the sum of gravitational Lindblad and co-orbital torques. We use high-resolution local simulations in an unstratified disk to assess the accuracy and domain of applicability of the linear theory. We find agreement between analytic and simulation results to better than 10\% in the appropriate regime (low luminosity, low thermal conductivity), but measure deviations in the non-linear (high luminosity) regime and in the high thermal conductivity regime. In the non-linear regime, linear theory overpredicts the acceleration due to the heating torque, which we find to be due to the neglect of non-linear terms in the heat flux. In the high thermal conductivity regime linear theory underpredicts the acceleration, although here both non-linear and computational constraints play a role. We discuss the impact of the heating torque for the evolution of low-mass planets in protoplanetary disks, and for massive stars or accreting compact objects embedded in AGN disks. For the latter case, we show that the thermal torque is likely to be the dominant physical effect at disk radii where the optical depth drops below a critical value.

description: The Leontief’s scheme and Sraffa’s model are significant examples in the field of linear models of analysis based on the assumption of the heterogeneity of capital goods and the homogeneity of work. This article aims to introduce the case of a non-homogeneous workforce within these same models and examine some initial implications. In particular, in the proposed model the different tasks, that is, the phases in which a manufacturing process can be divided, are performed by different types of specialized workers where the type of specialization considered is in turn produced in the same way as a good. On the basis of the specialization of the model, we can obtain a solution as the vector of prices and different wage rates of balance. JEL: J01, J30

description: In the WP4, different deterministic high-fidelity digital twins ofthe manufacturing processes of the OGV have been developed tomodel and to simulate the physics of the AFP, the RTM, the L-PBFand the assembly processes. The deterministic simulations of thedifferent steps of the processes were realized for the nominalconfigurations of the product / processes parameters. However,some of these parameters are uncertain in the real workshopenvironment. So, to be close to the real processes and materials,with their own variabilities, uncertainty quantification andpropagation strategies must be defined and integrated in thenumerical workflow. To ensure the uncertainty propagation inthe different deterministic processes simulations and digitaltwins, several “state of the art” methods have been selected infunction of the stochastic complexity of the deterministic modelsand simulations and of the computational times.

description: Cepas de rizobacterias asociadas con el cultivo de la yautia (Xanthosoma sagittifolium [L.] Schott) y antagonistas de Sclerotium rolfsii, Rhizoctonia solani, y Fusarium solani, agentes causales del mal seco de la yautia se probaron para determinar la resistencia a fungicidas. Se evaluaron los productos qulmicos Benomil (Benlate), Metilo- Etridiazol-Tiofanato (Ban Rot), Metalaxil (Ridomil), Azufre Elemental-Sulfato de Cobre Tribâsico (Top Cop). El crecimiento de algunas de las rizobacterias fue mayor en presencia de fungicidas que en el control. Los resultados indican la posibilidad de implementar estrategias combinadas de control quimico y biolôgico para la reducciôn del mal seco. La desinfecciôn preventiva de semillas de yautia con fungicidas que protegen contra los hongos patôgenos y que no inhiben el crecimiento de las rizobacterias antagonistas de estos hongos representan un potencial para el manejo integrado de la enfermedad bajo condiciones de campo.
Riflessioni sulla politica monetaria internazionale

description: The present article analyses the current state of international monetary policy and arrangements. The author first examines the nature of monetary arrangements guided by political institutions that are tempted to exploit the monetary system through the monopoly right to issue base money. The development of international institutions for controlling the monopoly right, the system of fixed exchange rates and the gold standard, and the eventual collapse of the Bretton Woods system are then reviewed. The recent development of the European Monetary System, its central issues and its prospects are then assessed. The author concludes that if the bureaucratic approach encouraged by the political process continues to disregard the one and only condition assuring a viable fix-rate system, that is sever constraints national monetary policies, the most likely outcome of the EMS will be a new series of speculative waves and an erratic monetary growth in the stronger currency areas with intermittent pressures on the stronger currency areas to accommodate the comparatively weaker area.

Productivity Analysis

description: Peanut (Arachis hypogea cv. 'Georgia Red') plants were grown, for periods of up to 109 days, in hydroponic culture, using ratios of modified (N:K = 1:2.4) Hoagland solution amended with the filtered effluent from aerobic bioreactors. The percentages of effluent used with the basal crop nutrient of modified half Hoagland (MHH) ranged from 0 to 100%. The source of effluent used in the studies were bioreactors from laboratory scale testing of aerobic biodégradation of inedible plant biomass. Experiments were conducted in Environmental Growth Chambers (EGC) with an average chamber volume of 2.1 m"3 and a day/night cycle of 12 h at 28°C and 12 h at 22°C. The average daily photon flux for the experiments reported was 600 μιηοΙ.πι"2^"1. The plants were grown at ambient CO2. Incorporating the effluent at ratios of 60% and higher were non-deleterious for peanut foliar growth. But increasing the effluent content caused a decline in the mean dry biomass per plant, with values for the MHH plants of 4.83±0.01 and of 2.1H0.15 and I.90±0.42 g/ plant, for the plants grown in 80% and 100% effluent, respectively. Also, the calcium content of effluent treated plants was significantly (P<0.05) reduced, when compared with control plants. The challenge facing researchers is the attainment of a balance between the maximum amount of effluent that may be utilized to provide nutrients for crop growth while not inducing a phytotoxic response.
A General Effective Theory for Dense Quark Matter

description: A general effective action for quark matter at nonzero temperature and/or nonzero density is derived. Irrelevant quark modes are distinguished from relevant quark modes, and hard from soft gluon modes, by introducing two separate cut-offs in momentum space, one for quarks, $Λ_q$, and one for gluons, $Λ_g$. Irrelevant quark modes and hard gluon modes are then exactly integrated out in the functional integral representation of the QCD partition function. Depending on the specific choice for $Λ_q$ and $Λ_g$, the resulting effective action contains well-known effective actions for hot and/or dense quark matter, for instance the ``Hard Thermal Loop'' (HTL) or the ``Hard Dense Loop'' (HDL) action, as well as the high-density effective theory proposed by Hong and others.

description: Gibberellins are bioregulators associated with yam tuber dormancy. When yam tubers were dipped in GA3 solution at concentration from 100-1000 ppm bud breaking never ocurred. Furthermore, bud breaking was delayed by three folds with GA3 at 1 ppm compared with the control. Similar effects were found with Promalin at concentration from 1-1000 ppm. Daminozide and Paclobutrazole also extended dormancy but in a less degree. None of the treatments inhibited the dormancy period compared with the control. Experiments were design to characterize giberellins in yam tubers. Methanol and ethyl acetate extracts were prepared from tuber tissue. Extracts were purified by adsortion chromatography using a polyvinylpolypirrolidone column followed by charcoal-celite column. Further purification was made using C-18 reversed phase HPLC. Fractions with biological activity were detected by the lettuce hypocotyl bioassay.
Doubly Special Relativity in Position Space Starting from the Conformal Group

description: We propose version of doubly special relativity theory starting from position space. The version is based on deformation of ordinary Lorentz transformations due to the special conformal transformation. There is unique deformation which does not modify rotations. In contrast to the Fock-Lorentz realization (as well as to recent position-space proposals), maximum signal velocity is position (and observer) independent scale in our formulation by construction. The formulation admits one more invariant scale identified with radius of three-dimensional space-like hypersection of space-time. We present and discuss the Lagrangian action for geodesic motion of a particle on the DSR space. For the present formulation, one needs to distinguish the canonical (conjugated to $x^μ$) momentum $p^μ$ from the conserved energy-momentum. Deformed Lorentz transformations for $x^μ$ induce complicated transformation law in space of canonical momentum. $p^μ$ is not a conserved quantity and obeys to deformed dispersion relation. The conserved energy-momentum $P^μ$ turns out to be different from the canonical one, in particular, $P^μ$-space is equipped with nontrivial commutator. The nonlinear transformations for $x^μ$ induce the standard Lorentz transformations in space of $P^μ$. It means, in particular, that composite rule for $P^μ$ is ordinary sum. There is no problem of total momentum in the theory. $P^μ$ obeys the standard energy-momentum relation (while has nonstandard dependence on velocity).

description: Whitefly-transmitted geminiviruses (Subgroup ΙΠ, Geminiviridae) have long recognized as pathogens of weed species and bean crops in Puerto Rico, and were recently shown to cause diseases of tomato. At least five symptoms phenotypes were associated with infected tomato in P.R. during 1991-1996. Geminivirus etiology was demonstrated by whitefly transmission and polymerase chain reaction (PCR) detection using subgroup III universal PCR primers. At least three distinct genotypes were discerned in infected tomato based upon comparison of key virus sequences with those of well-characterized subgroup III viruses. Each virus genotype has a unique experimental host range and causes differential symptoms in diagnostic test species. The precise relationships between P.R. viruses that are indigenous to weed hosts and those found in bean and tomato are under investigation in order to identify the most economically important viruses to target for resistance efforts, to map their distribution in host plants, and to evaluate the potential for recombination or reassortment in the formation of new and emerging geminiviruses.
