description: Given a directed graph $G$ and a pair of nodes $s$ and $t$, an \emph{$s$-$t$ bridge} of $G$ is an edge whose removal breaks all $s$-$t$ paths of $G$ (and thus appears in all $s$-$t$ paths). Computing all $s$-$t$ bridges of $G$ is a basic graph problem, solvable in linear time. In this paper, we consider a natural generalisation of this problem, with the notion of "safety" from bioinformatics. We say that a walk $W$ is \emph{safe} with respect to a set $\mathcal{W}$ of $s$-$t$ walks, if $W$ is a subwalk of all walks in $\mathcal{W}$. We start by considering the maximal safe walks when $\mathcal{W}$ consists of: all $s$-$t$ paths, all $s$-$t$ trails, or all $s$-$t$ walks of $G$. We show that the first two problems are immediate linear-time generalisations of finding all $s$-$t$ bridges, while the third problem is more involved. In particular, we show that there exists a compact representation computable in linear time, that allows outputting all maximal safe walks in time linear in their length. We further generalise these problems, by assuming that safety is defined only with respect to a subset of \emph{visible} edges. Here we prove a dichotomy between the $s$-$t$ paths and $s$-$t$ trails cases, and the $s$-$t$ walks case: the former two are NP-hard, while the latter is solvable with the same complexity as when all edges are visible. We also show that the same complexity results hold for the analogous generalisations of \emph{$s$-$t$ articulation points} (nodes appearing in all $s$-$t$ paths). We thus obtain the best possible results for natural "safety"-generalisations of these two fundamental graph problems. Moreover, our algorithms are simple and do not employ any complex data structures, making them ideal for use in practice.

description: The modified Mellin transform ${\cal Z}_k(s) = \int_1^\infty |ζ({1\over2}+ix|^{2k}x^{-s}{\rm d} x$ ($k\ge1$ is a fixed integer, $s = σ+ it$) is used to obtain estimates for $$ \sum_{r=1}^R\int_{t_r-G}^{t_r+G}|ζ(1/2+it)|^{2k}{\rm d} t\quad(T < t_1 < >... < t_R < 2T), $$ where $t_{r+1} - t_r \ge G (r =1,..., R-1), T^ε\le G \le T^{1-ε$. These results can be used to derive bounds for the moments of $}|ζ(1/2+it)|$.

description: Little theoretical work has been done previously on the welfare valuation of changes in price and quality when consumers are imperfectly informed. The presence of imperfect information is particularly important in the analysis of averting behaviors. We develop a theoretical welfare measure, called quasi-compensating variation, as a natural extension of compensating variation (CV). We show that this welfare measure offers not only a money metric of the "value of information", but also a means to appropriately evaluate the welfare effects of various policies when consumers are imperfectly informed of water contamination. With a numerical example and our decomposition results (Propositions 2 and 3), we demonstrate that (i) the value of information could potentially account for a large portion of the total welfare gains when regulators simultaneously disseminate accurate information and improve drinking water quality, (ii) the willingness to pay to avoid toxic contamination is strictly larger for imperfectly informed than perfectly informed consumers, and (iii) the distribution of imperfect information among consumers affects the relative performance of the two compelling policy alternatives, "self-protection" and "pollution control".

description: We present a two-pronged approach to the formation of early-type galaxies, using a sample of 18 galaxies at 0.5 < z < 1 from the HST/ACS Ultra Deep Field and GRAPES surveys: 1) We combine slitless low resolution spectroscopy from the GRAPES dataset with simple models of galaxy formation to explore their star formation histories. 2) We also perform an analysis of their surface brightness distribution with the unprecedented details provided by the ACS superb angular resolution and photometric depth. Our spectroscopic analysis reveals that their stellar populations are rather homogeneous in age and metallicity and formed at redshifts z ~ 2-5. Evolving them passively, they become practically indistinguishable from ellipticals at z = 0. Also, their isophotal shapes appear very similar to those observed for nearby ellipticals, in that the percentages of disky and boxy galaxies at z ~ 1 are close to the values measured at z = 0. Moreover,we find that the isophotal structure of z ~ 1 early-type galaxies obeys the correlations already observed among nearby ellipticals, i.e. disky ellipticals have generally higher characteristic ellipticities, and boxy ellipticals have larger half-light radii and are brighter in the restframe B band. In this respect then, no significant structural differences are seen for ellipticals between z = 0 and 1.

description: A combined fit is made to E791 data on D->K-pi-pi, LASS data on K-pi elastic scattering, and BES II data on J/Psi->K*(890)-K-pi.In all cases, the K-pi S-wave is fitted well with a kappa resonance and Ko(1430); the kappa requires an s-dependent width with an Adler zero near threshold. The pole position of the kappa is at M - iGamma/2 = (750 +30 -55) - i(342 +- 60) MeV. The E791 collaboration fitted their data using a form factor for the production process D->kappa-pi. It is shown that this form factor is not needed. The data require point-like production with an RMS radius <0.38 fm with 95 percent confidence.

U.S. and Canadian Livestock Prices: Market Integration and Trade Dependence

Year: 2006

description: Cointegration of Canadian and U.S. livestock prices points to the existence of market integration in the period 1996:1 to 2004:12 even though the trade flows of livestock and beef products were non-existent for many months in 2003 and 2004 (suggesting market segmentation) due to livestock/beef import bans by both countries due to BSE. It was also determined that Canada's trade dependence in livestock and beef is cointegrated with Canadian and U.S. livestock prices. However, as the trade dependence variable is shocked, the effects on Canadian and U.S. prices are opposite although one would expect that in an integrated market the price responses to an exogenous shock would be similar or statistically identical. This result reinforces the case against the use of cointegration in determining presence (or absence) of market integration. Empirical results in this article raise some very difficult questions. Gains from trade are well documented. Yet, once a country is very trade dependent, the prices in it are much more vulnerable to exogenous shocks that reduce the trade flows. Canadian livestock prices plummeted and stayed low following the BSE incident and U.S. (and Japanese) import bans on Canadian livestock and beef. Given the long cycles and high sunk cost in the livestock and beef industry, immediate adjustment (reduction in production) for Canadian producers was difficult and always unlikely. Moreover, the possibility of import bans being lifted in the near future may have further shaped their expectations and prolonged the decisions on herd reduction. In the meanwhile, U.S. prices increased following Canada's trade dependence shock due to BSE and remained above the original long-run equilibrium price.
Correlated disorder in a well relaxed model binary glass through a local SU(2) bonding topology

description: A quantitative understanding of the microscopic constraints which underlie a well relaxed glassy structure is the key to developing a microscopic theory of structural evolution and plasticity for the amorphous solid. Here we demonstrate the applicability of one such theory of local bonding constraints developed by D. R. Nelson [Phys. Rev. B 28, 5515 (1983)], for a model binary Lennard-Jones glass structure that has undergone an isothermal annealing simulation spanning over 10 micro-seconds of physical simulation time. By introducing a modified radical Voronoi tessellation which removes some ambiguity in how nearest neighbour bonds are enumerated, it is found, that a large proportion ($>95\%$) of local atomic environments follow the connectivity rules of the SU(2) topology of Nelson's work resulting in a dense network of disclination lines characterizing the defect bonds. Furthermore, it is numerically shown that a low energy glass structure corresponds to a reduced level of bond-length frustration and thus a minimally defected bond-defect network. It is then demonstrated that such a defect network provides a framework in which to analyse thermally-activated structural excitations, revealing those high-energy/low-density regions not following the connectivity constraints are more likely to undergo structural rearrangement that often results in a local relaxation that ends with the creation of new SU(2) local topology content.

description: We discuss a new leading-order parameterization of generalized parton distributions of the proton, which is based on the idea of duality. In its minimal version, the parameterization is defined by the usual quark singlet parton distributions and the form factors of the energy-momentum tensor. We demonstrate that our parameterization describes very well the absolute value, the Q^2-dependence and the W-dependence of the HERA data on the total DVCS cross section and contains no free parameters in that kinematics. The parameterization suits especially well the low-x_{Bj} region, which allows us to advocate it as a better alternative to the frequently used double distribution parameterization of the GPDs.

description: Smallpox, caused by the variola virus (VARV), was a highly virulent disease with high mortality rates causing a major threat for global human health until its successful eradication in 1980. Despite previously published historic and modern VARV genomes, its past dissemination and diversity remain debated. To understand the evolutionary history of VARV with respect to historic and modern VARV genetic variation in Europe, we sequenced a VARV genome from a well-described eighteenth-century case from England (specimen P328). In our phylogenetic analysis, the new genome falls between the modern strains and another historic strain from Lithuania, supporting previous claims of larger diversity in early modern Europe compared to the twentieth century. Our analyses also resolve a previous controversy regarding the common ancestor between modern and historic strains by confirming a later date around the seventeenth century. Overall, our results point to the benefit of historic genomes for better resolution of past VARV diversity and highlight the value of such historic genomes from around the world to further understand the evolutionary history of smallpox as well as related diseases.This article is part of the theme issue ‘Insights into health and disease from ancient biomolecules’.

description: Trade policy reform prospects have generated debate about the impacts on poverty. Some critics assert that price changes induced by trade reform are minimal and may not be distinguishable from price fluctuations induced by other shocks to the global economy. This paper addresses this issue by developing an approach to assess whether poverty changes induced by trade reform can be statistically discernable, based on a comparison in the grains sector. Fluctuations in grains markets are implemented by incorporating stochastic simulations into a CGE model of the global economy. The resulting price distributions are inputted to a micro-simulation based on national household surveys. The conclusions are based on the comparison of the resulting poverty distributions from the weather-induced variability only, versus the combined effect of the latter and trade reform. Results indicate that, in this conservative approach of evaluating only the global grains markets, the short-run impacts on poverty of trade liberalization can not be distinguished from market volatility in some countries.

description: We have started an ambitious program to determine if the full diversity of extinction laws is real or if some of it is due to calibration or methodological issues. Here we start by analyzing the information on NIR extinction in a 2MASS stellar sample with good quality photometry and very red colours. We calculate the extinction at 1 $μ$m, $A_1$, and the power-law exponent, $α$ ($A_λ= A_1 λ^{-α}$), for the 2MASS stars located in the extinction trajectory in the $H-K$ vs. $J-H$ plane expected for red giants with $A_1 > 5$ mag. We test the validity of the assumption about the nature of those stars, whether a single or multiple values of $α$ are needed, and the spatial variations of the results. Most ($\sim$83%) of those stars can indeed be explained by high-extinction red giants and the rest is composed of extinguished AGB stars (mostly O-rich), blended sources, and smaller numbers of other objects, a contaminant fraction that can be reduced with the help of Gaia} DR2 data. Galactic red giants experience a NIR extinction with $α\sim 2.27$ and an uncertainty of a few hundredths of a magnitude. There is no significant spread in $α$ even though our sample is widely distributed and has a broad range of extinctions. Differences with previous results are ascribed to the treatment of non-linear photometric effects and/or the contaminant correction. Future research should concentrate in finding the correct functional form for the NIR extinction law. In the appendix we detail the treatment of non-linear photometric effects in the 2MASS bands.

For the dumbbell shapes of recently synthesized particles consisting of two intersecting spheres and for lens-shaped particles with spherical surfaces we calculate the isotropic and anisotropic interaction parameters that determine the immersion free energy and the orientation-dependent depletion interaction between particles that are induced by the polymers. Exact results are obtained for random-walk like (ideal) polymer chains.

description: Exclusive non-leptonic two-body decays of $B$ mesons have been studied extensively in the past two decades within the framework of factorization. However, the exploration of the corresponding three-body case has only started recently, in part motivated by new data. We consider here the simplest non-leptonic three-body $B$ decays from the point of view of factorization, namely heavy-to-heavy transitions. We provide a careful derivation of the SCET/QCDF factorized amplitudes to NNLO in $α_s$, and discuss the numerical impact of NLO and NNLO corrections. We then study the narrow-width limit, showing that the three-body amplitude reproduces analytically the known quasi-two-body decay amplitudes, and compute finite-width corrections. Finally, we discuss certain observables that are sensitive to perturbative NLO and NNLO corrections and to higher Gegenbauer moments of the dimeson LCDAs. This is the first study of non-leptonic three-body $B$ decays to NNLO in QCD.

Classification of plant communities in Gwaii Haanas National Park Reserve and Haida Heritage Site

Year: 2009

description: Plant communities were classified and described for Gwaii Haanas National Park Reserve and Haida Heritage Site located on the Queen Charlotte Islands in British Columbia, Canada. Existing vegetation and environment data were compiled from various sources and assessed for their compatibility as an integrated database. The combined data set was subjected to floristic and physiognomic - floristic methods for vegetation classification using TWINSPAN. The results of each were assessed using multiple response permutation procedures (MRPP) and vegetation tabular analysis (VTAB) to determine which method was superior, based on the homogeneity of individual vegetation units and the presence of meaningful diagnostic species in each. Gradient analysis (Cannonical Correspondence Analysis) was also utilised in conjunction with classification results to explore vegetation - environment relationships. Each association was described individually and in a landscape context. Data considered for analysis in this study were deemed to be acceptable for amalgamation. A bias was detected in sampling distribution overall, favouring upland forests. Species identification effort varied between data sets, particularly with respect to the detection of bryophytes and graminoids. The physiognomic - floristic approach was determined to be moderately superior. This classification resulted in a hierarchical structure with 9 alliances, 20 associations and 12 subassociations. These associations range in an elevational gradient from estuarine meadows and rocky shoreline communities through upland forests and wetlands to subalpine parkland. Subalpine and alpine communities are limited in the study area and were poorly represented in the data. Most communities appear simplified, homogenous and poorly defined, in floristic composition. This has been ascribed to browsing pressure by introduced deer. This effect is particularly evident in the upland forest communities. Recommendations are made for future expansion of classification work in the protected area. Assessment of plant association distribution and abundance for conservation purposes is desirable but not possible due to a lack of spatial accuracy and poor correlation between plant associations and environmental attributes. Additional sampling which takes into consideration geographic stratification and positional accuracy will allow for more rigorous spatial analysis in the future.

description: In the present study, a biochemical-genetic analysis was performed to determine the relationship between isoenzyme polymorphism and the zebra mussel Dressena polymorpha body’s response to the harmful effects of the pesticides Cypermethrin and Chlopyrifos. The probable genetic control of four enzyme and protein groups - malate dehydrogenase, malate enzyme, superoxide dismutase and soluble proteins - was determined. Different intensity of expression of allelic products has been reported in individuals exposed to short- and long-term exposure to the pesticides Cypermethrin and Chlorpyrifos. The observed variability in the expression of superoxide dismutases, malate dehydrogenases and soluble proteins in control and experimental samples gives us reason to accept these enzyme and protein systems as markers for reporting the negative impact of the tested pesticides on the zebra mussel.
Trigger turbulent bands directly at low Reynolds numbers in channel flow using a moving-force technique

Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We show a method, for direct numerical simulations, to trigger and maintain turbulent bands directly at low Reynolds numbers in channel flow. The key is to impose a moving localised force which induces a local flow with sufficiently strong inflectional instability. With the method, we can trigger and maintain turbulent bands at Reynolds numbers down to $Re \simeq 500$. More importantly, we can generate any band patterns with desired relative position and orientation. The usual perturbation approach resorts to turbulent fields simulated at higher Reynolds numbers, random noise, or localised vortical perturbation, which neither assures a successful generation of bands at low Reynolds numbers nor offers a control on the orientation of the generated bands. A precise control on the position and orientation of turbulent bands is important for the investigation of all possible types of band interaction and for understanding the transition in channel flow at low Reynolds numbers.

description: The European Union sugar policies, in place for over 49 years, underwent a first major reform in 2005, yielding to mounting pressures coming from the EU 2004 enlargement, the recent EBA initiative to least developed countries and the recent WTO-panel ruling on EU sugar export subsidies. The reform package consists of lowering administrative prices as well as modifying the structure of production quotas leading to lower sugar production and bringing down subsidized export to within WTO limits. However, these reforms do not address other components of the EU sugar policies such as non-preferential tariffs, quota reallocation across regions, or opening up the competitive structure of the EU sugar industry. This makes it difficult to assess the economic and trade implications of the reform package. This paper offers a dual-modeling approach to examine the impact of the EU sugar policy reform on sugar production and prices in the EU, and the trade implications for third countries with particular distinction between preferential and non-preferential exporters.

description: The study evaluates the gains of avoiding data-dependent specification search on an estimation sample in an application to discrete choice models. We incorporate data splitting, the process by which the total available sample is randomly split in two or more sub-samples with the first (specification) sub-sample used for specification search, and the second (estimation) sub-sample used for obtaining clean estimates using the model chosen on the specification sub-sample according to a set criterion. We estimate 14 binary Logit models of the adoption of conservation tillage corresponding to the major sub-watersheds of the Upper Mississippi River Basin. For each of the sub-watershed models, we use the specification sub-sample to choose the explanatory variables that lead to the highest number of correct predictions provided that estimated coefficients are in conformity with economic theory. To evaluate the gains of avoiding specification search on the estimation sub-sample, we follow Gong (1986)[8] and calculate the expected excess error, which is a measure of excess optimism concerning model fit on the specification sample. We find that the excess optimism varies with the sub-watersheds and has a tendency to be larger for the sub-watersheds with smaller samples.

description: We consider general relativity with cosmological constant minimally coupled to the electromagnetic field and assume that the four-dimensional space-time manifold is a warped product of two surfaces with Lorentzian and Euclidean signature metrics. Field equations imply that at least one of the surfaces must be of constant curvature leading to the symmetry of the metric (``spontaneous symmetry emergence''). We classify all global solutions in the case when the Lorentzian surface is of constant curvature. These solutions are invariant with respect to the Lorentz SO(1,2) or Poincare IO(1,1) groups acting on the Lorentzian surface.

description: The elements of multifunctional agriculture are strongly related to national, regional and local conditions. This indicates that it is hard to find common measures, which could efficiently enhance multifunctionality in different areas with different agricultural conditions. In order to really enhance the multifunctional role of agriculture, there is a need for newly designed measures. A need exists to have information from the groups involved in agricultural policy. To respond to this need we apply the stated choice method to find out, which measures Finnish farmers prefer when the measures introduced include multifunctionality enhancing elements. We introduced to farmers 12 different measures involving different levels of targeting, contracting and monetary compensation. We estimated a multinomial logit model to explain farmers' first choice with respect to policy options introduced. The results show that farmers are willing to accept multifunctionality enhancing elements and complementary terms of support as a basis for agricultural policy. To ensure the fulfilment of these terms a need exists for a large enough compensation. In practice, this compensation needs to cover all the costs for farmers of fulfilling the terms introduced in any particular support scheme.

description: Free probability analogs of the basics of extreme-value theory are obtained, based on Ando's spectral order. This includes classification of freely max-stable laws and their domains of attraction, using ``free extremal convolutions'' on the distributions. These laws coincide with the limit laws in the classical peaks-over-threshold approach. A free extremal projection-valued process over a measure-space is constructed, which is related to the free Poisson point process.

description: We use hydrodynamical simulations of galaxy clusters and groups to study the effect of pre-heating on the entropy structure of the ICM. Our simulations account for non-gravitational heating of the gas either by imposing a minimum entropy floor at redshift z=3, or by considering feedback by galactic winds powered by supernova (SN) energy. In the adiabatic simulations we find that the entropy is increased out to the external regions as a consequence of the transition from clumpy to smooth accretion induced by extra heating. This result is in line with the predictions of the semi-analytical model by Voit et al. However, the introduction of radiative cooling substantially reduces this entropy amplification effect. While galactic winds of increasing strength are effective in regulating star formation, they have a negligible effect on the entropy profile of cluster-sized halos. Only in models where the action of the winds is complemented with diffuse heating corresponding to a pre-collapse entropy do we find a sizable entropy amplification out to the virial radius of the groups. Observational evidence for entropy amplification in the outskirts of galaxy clusters and groups therefore favours a scenario for feedback that distributes heating energy in a more diffuse way than predicted by the model for galactic winds from SN explosions explored here.

description: Finding the solutions of nonlinear operator equations has been a subject of research for decades but has recently attracted much attention. This paper studies the convergence of a newly introduced viscosity implicit iterative algorithm to a fixed point of a nonexpansive mapping in Banach spaces. Our technique is indispensable in terms of explicitly clarifying the associated concepts and analysis. The scheme is effective for obtaining the solutions of various nonlinear operator equations as it involves the generalized contraction. The results are applied to obtain a fixed point of λ-strictly pseudocontractive mappings, solution of α-inverse-strongly monotone mappings, and solution of integral equations of Fredholm type

Analysis of two members of the EXT family, EXT1 and EXT2 bearing ER-, Golgi-, and secretory vesicle-sorting motifs

description: EXT1 and EXT2 are type II transmembrane glycosyltransferases involved in the biosynthesis of heparan sulfate (HS) polysaccharide chains (McCormick et al., 2000). These two glycoproteins are found predominantly in the ER when overexpressed individually but form a Golgi-localized heterocomplex when co-transfected together (Kobayashi et al., 2000; McCormick et al., 2000). To examine the roles of the N-terminal domains of EXT1 and EXT2, a series of chimeric cDNAs were constructed with ER-, Golgi- and secretory vesicle-sorting motifs. These constructs were transiently expressed in mammalian cells and tested for in vivo HS biosynthetic activity, heterocomplex formation, and subcellular localization. All EXT1 chimeras were able to synthesize HS in vivo as determined by their ability to restore herpes simplex virus infectivity to normally resistant HS-deficient Sog9 cells, though with varying efficiencies. Sec-EXT1 and Sec-EXT2 were able to form a heterocomplex together despite the loss of their wild-type (wt) cytoplasmic N-termini, putative transmembrane domains and 10 aa of their stem regions, suggesting that the N-termini of EXT1 and EXT2 are not essential for heterocomplex formation. The steady state subcellular distribution of the chimeras was determined by indirect immunofluorescence microscopy. As specified by their sorting motifs, ER-EXT1 and ER-EXT2 distributed in staining patterns distinctive of the ER, and Sec-EXT1 and Sec-EXT2 displayed staining patterns indicative of secretory vesicles. Though Golgi-EXT1 and Golgi-EXT2 did result in perinuclear distribution, a majority of transfected cells exhibited staining patterns typically observed for ERGIC- or early Golgi-localization. Interestingly, when each of the EXT1 chimeric constructs was co-transfected with wt EXT2, both proteins co-localized together and exhibited a staining pattern characteristic of the Golgi regardless of their respective sorting signals. This suggests that when a wt anchoring partner is present, chimeric EXT Is are able to form a heterocomplex with wt EXT2 and localize to the Golgi. Taken together, the results presented in this thesis suggest that the major Golgi-localization mechanism used by EXT1 and EXT2 is hetero-oligomer formation as described in the kin recognition model (Nilsson et al., 1993) which hypothesizes that Golgi-resident proteins form complexes too large to enter transport vesicles and are thus retained in the Golgi.

description: With the development of farm management extension services in Australia, a need has arisen for an analytical technique which can be handled by extension officers and readily comprehended by farmers. Inter farm comparison met this need at a similar stage of development in the United States and United Kingdom, and its application to Australian conditions is discussed. Comparative analysis is presented as an integral feature of farm management accounting.
Stochastic Perturbation Theory and the Gluon Condensate

description: On the lattice searching for the gluon condensate is difficult because a large perturbative contribution to the expectation value of the action has to be subtracted before looking for a small contribution from a possible gluon condensate. The perturbative calculation therefore has to be very precise. We use a modified version of stochastic perturbation theory to calculate a perturbative series in a boosted coupling, which converges more rapidly than the series with the usual lattice coupling, reducing the uncertainties in our results. We do not see any condensate of dimension two, as suggested by some earlier lattice studies, but we do find a contribution from a dimension four condensate. The value of this condensate is approximately 0.04(1) GeV^4, but with large uncertainties.

description: We consider the explicit solution to the axisymmetric diffusion equation. We recast the solution in the form of a Mellin inversion formula, and outline a method to compute a formula for $u(r,t)$ as a series using the Cauchy residue theorem. As a consequence, we are able to represent the solution to the axisymmetric diffusion equation as rapidly converging series.

description: Primary production including subsistence production, accounts for about 60 per cent of the national income of Papua and New Guinea. The bulk of the indigenous people are subsistence farmers, or have contact with the cash economy through agriculture, and the agricultural industries provide virtually the sole source of export earnings. The position is nevertheless changing rapidly.

description: We present a systematic study on the strange and multi-strange particles production in Pb+Pb collisions at $\sqrt{S_{NN}} = 2.76$ TeV based on the PACIAE model simulations. Two different mechanisms, namely the single string structure variations and multiple string interactions, are implemented in the simulations. These modifications give rise to an enhancement of the string tension value involved in the Lund string fragmentation framework and generate more strange particles in the hadronic final state. By comparing the simulation results with the ALICE experimental data, it turns out that the inclusion of the variable effective string tension in the PACIAE model is capable to reach an improved agreement between theory and experiment on the strangeness production in Pb+Pb collisions.

Two-dimensional N=(2,2) super Yang-Mills theory on the lattice via dimensional reduction

description: The N=(2,2) extended super Yang-Mills theory in 2 dimensions is formulated on the lattice as a dimensional reduction of a 4 dimensional lattice gauge theory. We use the plaquette action for a bosonic sector and the Wilson- or the overlap-Dirac operator for a fermion sector. The fermion determinant is real and, moreover, when the overlap-Dirac operator is used, semi-positive definite. The flat directions in the target theory become compact and present no subtlety for a numerical integration along these directions. Any exact supersymmetry does not exist in our lattice formulation; nevertheless we argue that one-loop calculable and finite mass counter terms ensure a supersymmetric continuum limit to all orders of perturbation theory.
