Conformal field theory correlations in the Abelian sandpile mode

Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: We calculate all multipoint correlation functions of all local bond modifications in the two-dimensional Abelian sandpile model, both at the critical point, and in the model with dissipation. The set of local bond modifications includes, as the most physically interesting case, all weakly allowed cluster variables. The correlation functions show that all local bond modifications have scaling dimension two, and can be written as linear combinations of operators in the central charge -2 logarithmic conformal field theory, in agreement with a form conjectured earlier by Mahieu and Ruelle in Phys. Rev. E 64, 066130 (2001). We find closed form expressions for the coefficients of the operators, and describe methods that allow their rapid calculation. We determine the fields associated with adding or removing bonds, both in the bulk, and along open and closed boundaries; some bond defects have scaling dimension two, while others have scaling dimension four. We also determine the corrections to bulk probabilities for local bond modifications near open and closed boundaries.

This provides, by use of M. Bonk and O.

Characterization and crystalization of Gelsolin

Publisher: name: University of British Columbia
Year: 2010

description: Actin, a protein existing in all eukaryotic cells, is involved in such cellular processes as cell movement, cell division, apoptosis and so on. Gelsolin, which consists of six structurally similar domains (G1-G6), can regulate these processes by calcium activated disassembly of actin filaments. In inactive gelsolin, the six domains pack into a compact globule so that none of the actin binding sites are accessible. From inactive gelsolin to activated gelsolin, three latches are unlocked to expose actin binding sites. Although the structure of fully activated, intact gelsolin is not available, those of the C-terminal and N-terminal halves of gelsolin, respectively, each bound to one actin molecule, have been solved. These structures may be added on to a model for F-actin to generate a model for a gelsolin-capped actin filament. In order to test these models, we set about to crystallize complexes in which one, two and three actin units bind to one activated intact gelsolin, i.e. GA, GA₂ and GA₃, respectively. This thesis centers on purification, characterization and crystallization of GA, GA₂ and GA₃ complexes. We have crystallized GA, GA₂ and GA₃, respectively, as confirmed by size exclusion chromatography and gel electrophoresis. We also confirmed our GA₂ and GA₃ complexes by MALDI mass spectrometry experiments. Although only the N-terminal half of gelsolin bound to one actin is visible in our GA₂ and GA₃ crystals by X-ray diffraction analysis, the crystals possess a unit cell that is sufficiently large to accommodate the second half of gelsolin bound to a second actin in a variety of different positions. We are still awaiting diffraction data of GA crystals and EDC cross-linked GA₃ crystals. We also soaked GA₂ and GA₃ crystals in Tb³⁺ -containing solutions in order to investigate the exchangeability of Ca²⁺ in these complexes.

description: Starting point of the analysis are theoretical considerations about multi-causal reasons of the management influence on the entrepreneurial success. In the further continuation an economic model illustrating the guidance idea of multi-causality is presented as well as a statistical evaluation method coordinated with it. Basis for the statistical illustration of the multi-causal context is an causal-analytic evaluation procedure. A priori formulated causal relations between not observable exogenous and endogenous variables are illustrated by a structural model. The structural model corresponds to the logical starting point of the regression analysis to provide documentary evidence of cause and effect relations. The latent variables of the regression-analytic part are measured by observed indicator variables. The measuring model itself is closely related to the logical starting point of the factor analysis. The causal-analytic evaluation procedure thus links the measuring models with cause and effect models. The formulation and examination of hypotheses are explained by case studies as a result of limited data. It refers only to the context between the market-focused management and the entrepreneurial success on the one hand as well as production and technology-oriented management and the entrepreneurial success on the other. Further unresolved tasks like further dimensions of the management – like employee orientation or financial orientation – have to be analysed more in detail. This task also gains significance because changes in the relative relevance of the identified management dimensions are to be expected.

description: We consider the extreme value statistics of $N$ independent and identically distributed random variables, which is a classic problem in probability theory. When $N\to\infty$, fluctuations around the maximum of the variables are described by the Fisher-Tippett-Gnedenko theorem, which states that the distribution of maxima converges to one out of three limiting forms. Among these is the Gumbel distribution, for which the convergence rate with $N$ is of a logarithmic nature. Here, we present a theory that allows one to use the Gumbel limit to accurately approximate the exact extreme value distribution. We do so by representing the scale and width parameters as power series, and by a transformation of the underlying distribution. We consider functional corrections to the Gumbel limit as well, showing they are obtainable via Taylor expansion. Our method also improves the description of large deviations from the mean extreme value. Additionally, it helps to characterize the extreme value statistics when the underlying distribution is unknown, for example when fitting experimental data.

description: We extend knot contact homology to a theory over the ring $\mathbb{Z}[λ^{\pm 1},μ^{\pm 1}]$, with the invariant given topologically and combinatorially. The improved invariant, which is defined for framed knots in $S^3$ and can be generalized to knots in arbitrary manifolds, distinguishes the unknot and can distinguish mutants. It contains the Alexander polynomial and naturally produces a two-variable polynomial knot invariant which is related to the $A$-polynomial.

description: We carry out direct numerical simulation combined with adhesive discrete element calculations to investigate collision-induced breakage of agglomerates in homogeneous isotropic turbulence. Based on extensive simulation runs, an adhesion parameter Adn is constructed to quantify the possibility of occurrence of sticking, rebound, and breakage events. The collision-induced breakage rate is then formulated based on the Smoluchowski equation and a breakage fraction. The breakage fraction, defined as the fraction of collisions that result in breakage, is then analytically estimated by a convolution of the probability distribution of collision velocity and a universal transfer function. It is shown that the breakage rate decreases exponentially as the adhesion parameter Adn increases for doublets and scales as linear functions of the agglomerate size, with the slope controlled by Adn. These results allow one to estimate the breakage rate for early-stage agglomerates of arbitrary size. Moreover, the role of the flow structure on the collision-induced breakage is also examined. Violent collisions and breakages are more likely caused by particles ejected rapidly from strong vortices and happen in straining sheets. Our results extend the findings of shear-induced fragmentation, forming a more complete picture of breakage of agglomerates in turbulent flows.

description: The objective of this paper is to investigate the performance of different Value-at-Risk (VaR) models in the context of risk assessment in hog production. The paper starts with a description of traditional VaR models, i.e. Variance-Covariance-Method (VCM) and Historical Simulation (HS). We address two well known problems, namely the fat tailedness of return distributions and the time aggregation of VaR forecasts. Afterwards, Extreme-Value-Theory (EVT) is introduced in order to overcome these problems. The previously described methods are then used to calculate the VaR of hog production under German market conditions. It turns out that EVT, VCM, and HS lead to different VaR forecasts if the return distributions are fat tailed and if the forecast horizon is long. Finally, we discuss the strengths and weaknesses of these rather new risk management methods thereby trying to identify fields for potential applications in the agribusiness.

description: Recently, it was shown that fundamental gates for theoretically efficient quantum information processing can be realized by using single photon sources, linear optics and quantum counters. One of these fundamental gates is the NS-gate, that is, the one-mode non-linear sign shift. In this work, firstly, we prove by a new rigorous proof that the upper bound of success probability of NS-gates with only one helper photon and an undefined number of ancillary modes is bounded by 0.25. Secondly, we explore the upper bound of success probability of NS-gate with a new post-selection measurement. The idea behind this new post-selection measurement is to condition the success of NS-gate transformation to the observation of only one helper photon in whichever of the output modes.

description: In the current age of trade and financial openness, local economies in developing countries are becoming increasingly exposed to external investments. The objective of the proposed two-sector model with environmental externalities is to provide an insight into the interaction between external investors and local communities with a focus upon the different strategies and income sources available to each category. In this context, analysis suggests that environmental regulations and incentives offered in order to attract external capital investment (whether foreign or national) may have an un-uniform impact on the two typologies of actors.
Cones of ball-ball separable elements

description: Let B_1,B_2 be balls in finite-dimensional real vector spaces E_1,E_2, centered around unit length vectors v_1,v_2 and not containing zero. An element in the tensor product space E_1 \otimes E_2 is called B_1 \otimes B_2-separable if it is contained in the convex conic hull of elements of the form w_1 \otimes w_2, where w_1 \in B_1, w_2 \in B_2. We study the cone formed by the separable elements in E_1 \otimes E_2. We determine the largest faces of this cone via a description of the extreme rays of the dual cone, i.e. the cone of the corresponding positive linear maps. We compute the radius of the largest ball centered around v_1 \otimes v_2 that consists of separable elements. As an application we obtain lower bounds on the radius of the largest ball of separable unnormalized states around the identity matrix for a multi-qubit system. These bounds are approximately 12% better than the best previously known. Our results are extendible to the case where B_1,B_2 are solid ellipsoids.

description: Energy storage systems - in particular, Pumped Hydropower Storage (PHS) - will be increasingly important to support the transition of power systems toward zero emissions. The reason is that PHS can mitigate the variability and uncertainty of renewable energy production from solar and wind power to balance electricity demand with supply. In this paper, we propose an integer programming problem for PHS siting that uses a Digital Elevation Model (DEM) to meet an energy storage requirement. It assumes the existence of a reservoir, lake, or river, and decides where to build a reservoir that will constitute the PHS with the existing body of water. This model finds minimum-cost project candidates given parameters such as desired head, power, and operation time. The paper discusses different solution methods to assure reservoir closure and avoid its fragmentation. A heuristic explores the representations of the DEM, from more aggregate to more precise, to sequentially refine the solution based on the last selected site, which reduces computational effort. The formulation is general and the objective function includes both construction and equipment costs. Constraints are related to the energy storage target and reservoir closure based on the DEM. We illustrate the methodology by selecting multiple PHS projects next to the reservoir of the Sobradinho hydropower plant in Brazil. The result of this model can be seen as a bottom-up step that prepares PHS candidate projects to be considered by an integrated resource planning model in a top-down step, that would select from these shortlisted projects.

Investigation of neutron density distribution of $^{208}$Pb nucleus when the proton density is constrained to its experimental distribution

Publisher: name: arXiv
Year: 2020
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: In this study, two novel improvements for the theoretical calculation of the neutron distributions are presented. First, the available experimental proton distributions are used as a constraint rather than inferred from the calculation. Second, the recently proposed distribution formula, d3pF, is used for the neutron density, which is more detailed than the usual shapes, for the first time in nuclear structure calculation. A semi-microscopic approach for binding energy calculation is considered in this study, however, the proposed improvements can be introduced to any other approach. The ground state binding energy and neutron density distribution of $^{208}$Pb nucleus are calculated by optimizing the binding energy considering three different distribution formulae. The implementation of the proposed improvements leads to a qualitative and quantitative improvement in the calculation of the binding energy and neutron density distribution. The calculated binding energy agrees with the experimental value, and the calculated neutron density shows fluctuations within the nuclear interior, which agrees with the predictions of self-consistent approaches.

description: We propose a realistic approach to climate policy based on the Copenhagen Agreement to reduce Greenhouse Gases (GHGs) emissions. We assess by how much the non-binding, although official, commitments to reduce emissions made in Copenhagen will affect the level of world GHGs emissions in 2020. Our estimates are based on official communications to the UNFCCC, on historic data and on the Business-as-Usual scenario of the WITCH model. We are not interested in estimating the gap between the expected level of emissions and what would be needed to achieve the 2°C target. Nor do we attempt to calculate the 2100 temperature level implied by the Copenhagen pledges. We believe these two exercises are subject to high uncertainty and would not improve the current state of negotiations. Rather, we take stock of the present politically achievable level of commitment and suggest an effective way to push forward the climate policy agenda. The focus is on what can be done rather than on what should be done. To this end, we estimate the potential of the financial provisions of the Copenhagen Agreement to sponsor mitigation effort in Non-Annex I countries. Using scenarios produced with the WITCH model, we show that lower commitment on domestic abatement measures can be compensated by devoting roughly 50% of the Copenhagen financial provisions in 2020 to mitigation in Non-Annex I countries. The policy implications of our results will be discussed.

description: The sensory evaluation of cocoa has become increasingly important, both at the research and production level. With a trained tasting panel, a series of cocoa liquors, from different origins in the main cocoa-producing areas of Venezuela, have been evaluated. The objective of this research was to update the wheels of flavors and aromas of Venezuela cocoa by including new types of cocoa and other producing areas from the first edition of these wheels in 2013. The cocoa samples that participated in the research, they come from different producers from all over the country, they underwent the following stages: selection, reception, coding, physical analysis of the grains, elaboration of the liquor and tasting. Thanks to the palatability of Venezuelan cocoa, the panelists identified typical venezuelan cocoa descriptors, which allowed the development of a new wheel of odors and flavors by profiles. The new scents are; wild flowers, forest, herbal, tobacco, spicy cloves, wine, guava, coconut, cherries, banana, fermented fruits, and perfume. While the new flavors are; caramel, ripe banana, plums, brown sugar, dried wood, nuts, tangerine, apple, peach and cinnamon. With these additional descriptors, the diversity of odors and Venezuelan cocoa is expanded, which allows discriminating cocoa by type and quality, being the new areas evaluated, Trincheras, Canoabo, Patanemo in the Carabobo state; Tucupita in Delta Amacuro state; The Azulita, Santa Cruz of Mora and Zea in Mérida state; The Tendida in Táchira state; Barinitas and Socopó in Barinas state; San Felipe in the Yaracuy state and Alto Apure, in Apure.

description: Funding adaptation requires adequate governance and there are different ways to organise and channel the funds to where it is most efficient and most necessary. This paper investigates this issue and studies the practical implementation of a development under conditionality, namely adaptation-development, and its requirement in terms of financing architecture. To contribute to this research, it looks at similar problems that have been met in the past, namely the European funding programs for Eastern Europe countries that were candidates to adhesion, and European internal structural and cohesion funds. These funding examples provide a pertinent analogy for the adaptation problem, and most issues in adaptation finance have also been met in these funds (difficulty to define and measure additionality and incremental cost, concept fuzziness, need for leverage and mainstreaming, ownership and sovereignty issues). Publicly available documents from the European Commission and the European Court of Auditors are reviewed, providing interesting insights into possible implementation of adaptation finance. These insights can be summarized into seven main lessons: (1) “black-spot” programs are less flexible but more efficient than “concept-based” programs; (2) a multi-scale and multi-step approach can minimize sovereignty and ownership issue, and facilitate capacity building; (3) private funding leverage is a myth, and funding based on the “additional cost” is highly inefficient; (4) non substitutability among objectives and regions is necessary; (5) sub-national eligibility criteria are a viable solution; (6) institutional capacity matter: low-capacity countries should focus on capacity building and “black-spot” strategies; higher-capacity countries can follow a concept-based approach; and (7) the EU should use its own experience to promote its views of adaptation funds.

description: It is clear that climate change involves changes in temperature and precipitation and therefore directly affects land productivity. However, this is not the only channel for climatic change to affect agro-systems. Biodiversity is subject to climatic fluctuations and in turn may alter land productivity too. Firstly, biodiversity is an input into agro-ecosystems. Secondly, biodiversity supports the functioning of these systems (e.g. the balancing of the nutrient cycle). Thirdly, agro-systems also host important wildlife species which, though not always, play a functional role in land productivity, nonetheless constitute important sources of landscape amenities. The present paper illustrates a unique attempt to economically assess this additional effect climate change may imply on agriculture. We first empirically evaluate changes in land productivity due to climatic change effect on temperature, precipitations and biodiversity. Then we estimate the economic cost of biodiversity impact on agro-systems. Our key finding is that climate-change-induced biodiversity impact on European agro-systems measured in terms of GDP change in year 2050 is sufficiently large to deepen the direct climate-change effect in some regions and to reverse it in others. Different economies show different resilience profiles to deal with this effect.
Deliberation in representative institutions: an analytical framework for a systemic approach

description: This article presents a novel analytical account of the relationship between deliberation and representation by reconstructing the specific institutional logics that guide deliberative action in parliaments. In contrast to the dominant generalised paradigm in empirical deliberation research it develops a contextualised-systemic approach. The article argues that the parliamentary context is characterised by a tension between two equally legitimate institutional logics: a discursive one, institutionalised through parliamentary procedures, and a positional one, constituted by relations of representation. The resulting theoretical model links the specific institutional and situational conditions to different forms and functions of deliberation. Depending on the specific balance between both logics deliberation fulfils functions of either integration or contestation. The model is applied to a comparative analysis of different cases of parliaments demonstrating how this account can advance both the comparative analysis of deliberation in representative institutions and the development of deliberative democracy after the systemic turn.
Donor atom substitutions in amidophosphine ligands : early transition metal complexes of arsine and aryloxide containing ligands

description: The effects of donor atom substitution in the amidophosphine ligands [sup PH][P₂N₂] (where [sup PH][P₂N₂] = PhP(CH₂SiMe₂NSiMe₂CH₂) ₂PPh) and [sup PH][NPN] (where [NPN] = PhP(CH₂SiMe₂NPh) ₂ with both stronger and weaker donors is explored through early transition metal coordination chemistry. The diamidodiarsine macrocycle Ph[As₂N₂] (where [sup PH][As₂N2₂] = [sup PH]As(CH₂SiMe₂NSiMe₂CH₂)₂AsPh) can be synthesized as a 1,4-dioxane adduct of the dilithium salt, [sup PH][As₂N₂]Li₂ ( 1,4-dioxane). Reactions of the lithium salt with appropriate metal halides affords the complexes [sup PH][As₂N₂]ZrCl₂ ,[sup PH][As₂N₂]TiCl₂ and ([sup PH][As₂N₂]Y) ₂ (μ-Cl) ₂, The yttrium complex is the first structurally characterized complex containing an yttrium arsenic bond. Attempts to reduce the halide salts in the presence of dinitrogen lead to mixtures of products, and evidence points to the reduction of arsenic within the macrocycle. The chelating diamidoarsine [sup PH] [NAsN] (where [sup PH] [NAsN] = PhAs(CH₂SiMe₂NPh)₂) can be synthesized as a THF adduct of the lithium salt, [sup PH] [NAsN]Li₂ (THF)₂ . Reaction of the lithium salt with TaMe₃Cl₂ affords the fivecoordinate alkyl complex [sup PH][NAsN]TaMe₃ . Hydrogenation of [sup PH] [NAsN]TaMe₃ does not produce a hydride complex, but instead a modest yield of the protonated ligand precursor [sup PH] [NAsN]H₂. Evidence suggests that [sup PH] [NAsN]H₂ is produced through hydrogenation of tantalum-amide bonds. Density functional theory calculations carried out on the model complexes 'NAsN'TaMe₃ and ('NAsN'Ta)₂ (μ-H)4 (where 'NAsN' CH₃As(CH₂SiH₂NCH₃)₂ ) suggest that dissociation of the arsenic donor may play a role in the hydrogenation of the trimethyl complex. The bis(aryloxy)phosphine ligands R[OPO] (where [sup R][OPO] = RP(3,5- (Bu₂C₆H₂0 ) ₂) (R = Ph, 'Pr) are prepared as dimeric lithium salts ([sup R][OPO]Li₂)₂ (THF)₄, protonated ligand precursors R[OPO]H₂ , the dimeric potassium salt ([sup PH] [OPO]K₂)₂ (THF)₆, and trimeric ([sup Pr][OPO]K₂)₃(THF)₃ . Reaction of [OPO] precursors with group 4 and 5 halides affords [sup PH][OPO]MCl₂ (THF) (M = Ti, Zr, Hi) and R[OPO]TaCl₃ . Direct alkylations of [sup PH][OPO]TaCl₃ produce only mixtures of products; however, the methyl complexes [sup PH][OPO]TaMeC₂ , [sup PH][OPO]TaMe₂Cl and [sup PH][OPO]TaMe₃ can be prepared by reaction of [sup PH][OPO] precursors with TaMe₃Cl₂. Alkylation and reduction chemistry of the halide complexes is dominated by the formation of bis-ligand complexes, including [sup PH][OPO]₂Ti, likely a result of the reduced steric bulk that is inherent to these metal-ligand systems. Preliminary investigations suggest it may be possible to prepare dinitrogen complexes through reactions with hydrazine and substituted hydrazines, or through ligand exchange with the dinitrogen complex [TaCl₃(THF)₂] ₂ (μ-N₂).

description: The Value of a Statistical Life is a key input into the calculation of the benefits of environmental policies that save lives. To date, the VSL used in environmental policy analyses has not been adjusted for age or the cause of death. Air pollution regulations, however, are linked to reductions in the risk of dying for cancer, heart disease, and respiratory illnesses, raising the question whether a single VSL should be applied for all of these causes of death. We conducted a conjoint choice experiment survey in Milan, Italy, to investigate this question. We find that the VSL increases with dread, exposure, the respondents’ assessments of the baseline risks, and experience with the specific risks being studied. The VSL is higher when the risk reduction is delivered by a public program, and increases with the effectiveness rating assigned by the respondent to public programs that address specific causes of death. The effectiveness of private risk-reducing behaviors is also positively associated with the VSL, but the effect is only half as large as that of public program effectiveness. The coefficients on dummies for the cause of death per se—namely, whether it’s cancer, a road traffic accident or a respiratory illness—are strongly statistically significant. All else the same, the fact that the cause of the death is “cancer” results in a VSL that is almost one million euro above the amount predicted by dread, exposure, beliefs, etc. The VSL in the road safety context is about one million euro less than what is predicted by dread, exposure, beliefs, etc. These effects are large, but the majority of the variation in the VSL is accounted for by the public program feature, the effectiveness of public programs at reducing the indicated risk, and dread. The effects of exposure and experience are smaller. These results raise the question whether using VSL figures based on private risk reduction, which is usually recommended to avoid double-counting, severely understates how much a society might be willing to pay for public safety.

description: Several large-scale experimental facilities and space-missions are being suggested to probe the universe across the gravitational-wave (GW) spectrum. Here we propose Gravitational-wave Lunar Observatory for Cosmology (GLOC) - the first concept design in the NASA Artemis era for a GW observatory on the Moon. Using feasible interferometer technologies, we find that a lunar-based observatory is ideal for probing GW frequencies in the range between deci-Hz to 5 Hz, an astrophysically rich regime that is very challenging for both Earth- and space-based detectors. GLOC can survey binaries with neutron stars, stellar and intermediate-mass black holes to $\gtrsim 70\%$ of the observable volume of our universe without significant background contamination. The sensitivity at $\mathcal{O}(1~\mathrm{Hz})$ allows a unique window into calibrating Type Ia supernovae. At its ultimate sensitivity limits, GLOC would trace the Hubble expansion rate up to redshift $z \sim 3$ and test General Relativity and $Λ$CDM cosmology up to $z\sim 350$.

Effect of Spin Current on Uniform Ferromagnetism: Domain Nucleation

description: Large spin current applied to a uniform ferromagnet leads to a spin-wave instability as pointed out recently. In this paper, it is shown that such spin-wave instability is absent in a state containing a domain wall, which indicates that nucleation of magnetic domains occurs above a certain critical spin current. This scenario is supported also by an explicit energy comparison of the two states under spin current.

description: Sensitive ac susceptibility measurements of a topological insulator, Bi$_2$Se$_3$ single crystal, using mutual two coil inductance technique (Ref. 32) shows coupling and decoupling of high conducting surface states. The coupling of the surface states exists upto thickness of 70 microns, which is much larger than the direct coupling limit of thickness approximately 5 to 10 nanometers found in thin films. The high conducting topological surface states are coupled through the crystal via high electrically conducting channels, generated by Selenium vacancies. These conducting channels through the bulk disintegrate beyond 70 micron thickness and at high temperatures, thereby leading to decoupling of the topological surface states. We show the decoupled surface states persist upto room temperature in the topological insulator. Analysis of Nyquist plot of ac-susceptibility response of the TI using a resistor (R) Inductor (L) model shows an inductive nature of the coupling between surface states found in these Bi$_2$Se$_3$ crystals.

description: This paper used the Uganda National Household Survey (UNHS) data set of 2005/06 to examine the productivity of improved inputs used by smallholder maize farmers in Uganda. Yield and gross profit functions were estimated with the stochastic frontier model. Results revealed a significant effect improved inputs use on yield but not gross profit. Moreover, farmers who planted recycled seed (of improved variety) without fertilizer obtained lower yield but the highest gross profit. Furthermore, if the opportunity cost of own land and labour inputs in maize production were imputed, overall, farmers made economic losses. Based on the prevailing farmers’ production technology and market conditions, maize cultivation in the range of 2‐3 ha was found to give optimum profit while cultivation under 1 ha or above 4 ha led to economic losses. A major contribution of this paper is that maize cultivation in Uganda in 2005/06 and even at present was/may be of no economic consequence other than food, at household level.

description: Using an N-body/SPH code, we explore the scenario in which a dwarf elliptical galaxy (dE) is subjected to ram-pressure stripping due to the intracluster medium (ICM). Our simulations show that while (i) smaller dEs lose their ISM almost immediately after entering the cluster, (ii) more massive dEs are able to retain their gas for considerable timespans.

Triple-pomeron dynamics: valence vs. glue

description: Three pomerons are known to couple via the gluon loop and interactions of this kind which are responsible for high-mass diffraction are described in terms of the gluonic structure function of the QCD pomeron. We show that the triple-pomeron coupling via the light quark loop associated with the ``valence'' in the pomeron is of the same strength as the purely gluonic coupling. The large $Q^2$ behavior of this new contribution is described by the DLLA evolution from the non-perturbative $f\bar f$ valence state of the pomeron. Numerical estimates of the high-mass diffraction structure functions based on the consistent account of both couplings are in good agreement with experimental data.

On three-point functions in ABJM and the latitude Wilson loop

description: I consider three-point functions of twist-one operators in ABJM at weak coupling. I compute the structure constant of correlators involving one twist-one un-protected operator and two protected ones for a few finite values of the spin, up to two-loop order. As an application I enforce a limit on the gauge group ranks, in which I relate the structure constant for three chiral primary operators to the expectation value of a supersymmetric Wilson loop. Such a relation is then used to perform a successful five-loop test on the matrix model conjectured to describe the supersymmetric Wilson loop.
