description: We find constrained instantons in Einstein gravity with and without a cosmological constant. These configurations are not saddle points of the Einstein-Hilbert action, yet they contribute to non-perturbative processes in quantum gravity. In some cases we expect that they give the dominant contribution from spacetimes with certain fixed topologies. With negative cosmological constant, these metrics describe wormholes connecting two asymptotic regions. We find many examples of such wormhole metrics and for certain symmetric configurations establish their perturbative stability. We expect that the Euclidean versions of these wormholes encode the energy level statistics of AdS black hole microstates. In the de Sitter and flat space settings we find new homogeneous and isotropic bounce and big bang/crunch cosmologies.

description: Declines in dairy farm numbers and milk production in Minnesota and Wisconsin continue to cause concern to the industry and stimulate activities and proposals to reverse the trend. But, simply viewing the aggregate changes in the states' industries overlooks some of the more positive changes in industry structure. The purpose of this article is to utilize the data that have recently been made available from the 1992 Census of Agriculture to illustrate some divergent trends in dairy farm structure and to make some projections of future industry structure in these two states.

(Figs. 6–10, 13–14)
 Material examined. 3 males, China: Hubei Province, Jingshan County, Lulin, Tianmenguan village, 31.2836 N, 113.0814 E, light trap, 2010. VII.11, Qifei Liu.
 Distribution. China, Laos, Myanmar, Vietnam, Thailand.
 Diagnosis. The present species appears to be a member of the difficult N. cavalerieri (Navás) complex that occurs throughout Southeast Asia and has been shown to exhibit considerable variation among taxa (Sivec & Zwick 1987; Stark & Sivec 2008). The three males exhibit little variation in aedeagal armature in the numbers of sac spines; aedeagal sac with only small spiny cushion of basodorsal spines and three irregular rows of ventral spines (Fig. 9–10, 13–14). We provide illustrations for aiding the recognition of this species from Hubei Province.

description: We report on 1.6 and 5.0 GHz observations of the ultraluminous infrared galaxy (ULIRG) Mrk 273, using the European VLBI Network (EVN) and the Multi-Element Radio-Linked Interferometer Network (MERLIN). We also make use of published 1.4 GHz VLBA observations of Mrk 273 by Carilli & Taylor (2000). Our 5 GHz images have a maximum resolution of 5-10 mas, which corresponds to linear resolutions of 3.5-7 pc at the distance of Mrk 273, and are the most sensitive high-resolution radio observations yet made of this ULIRG. Component N1, often pinpointed as a possible AGN, displays a steep spectral index ($α= 1.2 \pm 0.1; S_ν\propto ν^{-α}$); hence it is very difficult to reconcile with N1 being an AGN, and rather suggests that the compact nonthermal radio emission is produced by an extremely high luminous individual radio supernova (RSN), or a combination of unresolved emission from nested supernova remnants (SNR), luminous RSNe, or both. Component N2 is partly resolved out into several compact radio sources --none of which clearly dominates-- and a region of extended emission about 30 pc in size. The integrated spectral index of this region is flat ($α= 0.15 \pm 0.1$), which can be interpreted as due to a superposition of several unresolved components, e.g., RSNe or SNRs, whose radio emission peaks at different frequencies and is partially free-free absorbed. The overall extended radio emission from component N is typical of nonthermal, optically thin radio emission ($α= 0.8 \pm 0.1$), and its 1.4 GHz luminosity ($L_{1.4 \rm GHz} = (2.2 \pm 0.1)\times 10^{23} $ WHz$^{-1}$) is consistent with being produced by relativistic electrons diffused away from supernova remnants in an outburst.

description: This paper contributes new insights into discretizing Coulomb collisions in kinetic plasma models. Building on the previous works [Carrillo et al. J. Comp. Phys. X 7:100066 (2020), Hirvijoki and Burby Phys. Plasmas 27(8):082307 (2020)], I propose deterministic discrete-time energy- and positivity-preserving, entropy-dissipating marker-particle schemes for the standard Landau collision operator and the electrostatic gyrokinetic Landau operator. In case of the standard Landau operator, the scheme preserves also the discrete-time kinetic momentum. The improvements, the extensions of the structure-preserving discretizations in [Carrillo et al. J. Comp. Phys. X 7:100066 (2020), Hirvijoki and Burby Phys. Plasmas 27(8):082307 (2020)] to discrete time, are made possible by exploiting the underlying metriplectic structure of the collision operators involved and the so-called discrete-gradient integrators.

title: The Common Agricultural Policy: A Benefit or Barrier to Biodiversity Conservation in General and Bird Conservation in Particular?
Creators: name: Butler, Maya
Publisher: name: University of Kent
Year: 2015

description: The Common Agricultural Policy (CAP) is the principal agricultural framework for the 28 Member States of Europe. It provides subsidies to promote efficient, environmentally sustainable, productive farming practices. The environment and the conservation of wildlife thus form an integral component of CAP via two ‘pillars’: the newly introduced “greening” in Pillar I, which will come into effect in 2015 and the agri-environmental schemes of Pillar II. Whether changes such as greening will be more or less advantageous to the environment remains to be seen. This thesis examines the role that CAP and its schemes (current and proposed) play in biodiversity conservation, as well as the attitudes of key stakeholders towards them. Research objectives include critiquing the agri-environmental schemes of the 2007-2013 CAP and forecasting the likely uptake of new schemes in the 2014-2020 reformed CAP, as well as the potential biodiversity value of these. Surveying a range of key stakeholders from research sites in East Kent and North Cornwall, as well as representatives from Parliament and the European Commission, I used a mixed-methods approach – postal survey and in-depth interviews. I hypothesised that scheme uptake would be limited due to financial constraints, compliance issues and bureaucracy, but that with greening, biodiversity outcomes would likely be reached. My research uncovered the threat that, because greening will be an annual non-contractual agreement that dilutes restrictions and compliance, making sustained environmental gains questionable, farmers may disregard schemes because of greening such that the outcomes for wildlife could be jeopardised. However, with more stakeholder collaboration and further policy refinement, CAP does have the potential to successfully promote its aims of conservation and food production.

description: We consider the incompressible 3D Navier-Stokes equations subject to a shear induced by noisy movement of part of the boundary. The effect of the noise is quantified by upper bounds on the first two moments of the dissipation rate. The expected value estimate is consistent with the Kolmogorov dissipation law, recovering an upper bound as in [15] for the deterministic case. The movement of the boundary is given by an Ornstein-Uhlenbeck process; a potential for over-dissipation is noted if the Ornstein-Uhlenbeck process were replaced by the Wiener process.

description: A Schrödinger-cat state is a coherent superposition of macroscopically distinguishable quantum states, in quantum optics usually realized as superposition of coherent states. Protocols to prepare photonic cats have been presented for atomic systems. Here, we investigate in what manner and how well the preparation protocols can be transferred to a solid state platform, namely a semiconductor quantum-dot--cavity system. In quantum-dot--cavity systems there are many disruptive influences like cavity losses, the radiative decay of the quantum dot, and the pure-dephasing type coupling to longitudinal acoustic phonons. We show that for one of the protocols these influences kill the quantum coherence between the states forming the cat, while for a second protocol a parameter regime can be identified where the essential characteristics of Schrödinger-cat states survive the environmental influences under realistic conditions.

Subjects: chain goals; consumer perceptions; traditional food products

description: Organizations no longer compete as independent entities, but as chains (Christopher, 1998; Cox, 1999; Lambert, Cooper, 2000). Consequently, chain strategies became more important in creating competitive advantage (Vickery et al., 2003; Gunasekaran et al., 2004). Despite the growing recognition of the importance of chain strategies, many chains active in the agri-business sector still face difficulties in developing common chain strategies and implementing them collaboratively to generate additional mutual gains and savings. Chains lacking a chain strategy and having short-term perspectives face difficulties in envisaging and implementing cooperative solutions to problems they cannot manage alone. Despite this recognition, the actual development of such chain strategies lags behind because of some particular issues which still need to be addressed (e.g. vision, mission, values or action plans). Therefore, the objective of this paper is to identify and consolidate chain members’ goals, to select a minimum set of key goals and to confront these chain goals with consumer preferences. This way, the paper develops the vision of traditional food chains in the EU, as a first step of strategy development. First, chain members goals are identified and consolidated with the help of approximately 100 stakeholders (suppliers, focal companies, customers) from three European countries representing 5 traditional food product categories (cheese, beer, dry ham, dry sausage and white pepper). The most important goals of traditional food chains are to maintain traditionalism, to improve responsiveness, to maintain superior quality and to create chain balance. These chain goals are tested against the perception of 4828 consumers from six European countries (Belgium, France, Italy, Norway, Poland and Spain). As a result, the vision of traditional food chains is developed: the European traditional food sector envisions a competitive sector maintaining the traditional character and superior quality of their food product(s) via more efficient and responsive chains where risks and benefits are distributed in a balanced way between the members.

description: This paper describes the first measurement of b-quark fragmentation fractions into bottom hadrons in Run II of the Tevatron Collider at Fermilab. The result is based on a 360 pb-1 sample of data collected with the CDF II detector in p-pbar collisions at sqrt{s}=1.96 TeV. Semileptonic decays of B0, B+, and B_s mesons, as well as Lambda_b baryons, are reconstructed. For an effective bottom hadron p_T threshold of 7 GeV/c, the fragmentation fractions are measured to be f_u/f_d=1.054 +/- 0.018 (stat) +0.025-0.045(sys) +/- 0.058 (Br), f_s/(f_u+f_d)=0.160 +/- 0.005 (stat) +0.011-0.010 (sys) +0.057-0.034 (Br), and f_{Lambda_b}/(f_u+f_d)=0.281\pm0.012 (stat) +0.058-0.056 (sys) +0.128-0.086 (Br), where the uncertainty (Br) is due to uncertainties on measured branching ratios. The value of f_s/(f_u+f_d) agrees within one standard deviation with previous CDF measurements and the world average of this quantity, which is dominated by LEP measurements. However, the ratio f_{Lambda_b}/(f_u+f_d) is approximately twice the value previously measured at LEP. The approximately 2 sigma discrepancy is examined in terms of kinematic differences between the two production environments.

Thin accretion disk signatures of scalarized black holes in Einstein-scalar-Gauss-Bonnet gravity

description: Einstein-scalar-Gauss-Bonnet gravity has recently been known to exhibit spontaneous scalarization. In the presence of the Gauss-Bonnet term the no-hair theorem can be evaded and novel black hole solutions with non-trivial scalar fields have been found besides the general relativistic solutions. In this paper, we aim to investigate the possibility of observationally testing Einstein-scalar-Gauss-Bonnet gravity using thin accretion disk properties around such scalarized black holes. Using the Novikov-Thorne model, we numerically calculate the electromagnetic flux, temperature distribution, emission spectrum, innermost stable circular orbits and energy conversion efficiency of accretion disks around such black holes and compare the results with the standard general relativistic Schwarzschild solution. We find that the accretion disks around scalarized black holes are hotter and more luminous than in general relativity.

Lorentz symmetry violation without violation of relativistic symmetry

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Within the framework of the Finslerian approach to the problem of violation of Lorentz symmetry, consideration is given to a flat axially symmetric Finslerian space of events, which is the generalization of Minkowski space. Such an event space arises from the spontaneous breaking of initial gauge symmetry and from the formation of anisotropic fermion-antifermion condensate. It is shown that the appearance of an anisotropic condensate breaks Lorentz symmetry; relativistic symmetry, realized by means of the 3-parameter group of generalized Lorentz boosts, remains valid here nevertheless. We have obtained the bispinor representation of the group of generalized Lorentz boosts, which makes it possible to construct the Lagrangian for an interaction of fundamental fields with anisotropic condensate.

Economic Dynamics of the German Hog-Price Cycle

description: We investigated the economic dynamics of the German hog-price cycle with an innovative ‘diagnostic’ modeling approach. Hog-price cycles are conventionally modeled stochastically—most recently as randomly-shifting sinusoidal oscillations. Alternatively, we applied Nonlinear Time Series analysis to empirically reconstruct a deterministic, low-dimensional, and nonlinear attractor from observed hog prices. We next formulated a structural (explanatory) model of the pork industry to synthesize the empirical hog-price attractor. Model simulations demonstrate that low price-elasticity of demand contributes to aperiodic price cycling – a well know result – and further reveal two other important driving factors: investment irreversibility (caused by high specificity of technology), and liquidity-driven investment behavior of German farmers.

description: The Configuration Interaction (CI) method using a very large Laguerre orbital basis is applied to the calculation of the He ground state. The largest calculations included a minimum of 35 radial orbitals for each l ranging from 0 to 12 resulting in basis sets in excess of 400 orbitals. The convergence of the energy and electron-electron delta-function with respect to J (the maximum angular momenta of the orbitals included in the CI expansion) were investigated in detail. Extrapolations to the limit of infinite in angular momentum using expansions of the type Delta X_J = A_X/(J+1/2)^p + B_X/(J+1/2)^(p+1) + ..., gave an energy accurate to 10^(-7) Hartree and a value of accurate to about 0.5%. Improved estimates of and , accurate to 10^(-8) Hartree and 0.01% respectively, were obtained when extrapolations to an infinite radial basis were done prior to the determination of the J -> infty limit. Round-off errors were the main impediment to achieving even higher precision since determination of the radial and angular limits required the manipulation of very small energy and differences.

description: In this paper we present normal state magnetoresistivity data of magnesium diboride epitaxial thin films with different levels of disorder, measured at 42K in magnetic fields up to 45 Tesla. Disorder was introduced in a controlled way either by means of neutron irradiation or by carbon doping. From a quantitative analysis of the magnetoresistivity curves with the magnetic field either parallel or perpendicular to the plane of the film, we extract the ratio of the scattering times in p- and s-bands. We demonstrate that the undoped unirradiated thin film has p scattering times smaller than s ones; upon irradiation, both bands become increasingly more disordered; eventually the highly irradiated sample (neutron fluence 7.7X1017 cm-2) and the C-doped sample have comparable scattering times in the two types of bands. This description of the effect of disorder in the two kinds of bands on transport is consistent with the residual resistivity values and with the temperature dependence of the resistivity.

Based on detailed CORSIKA energy deposit simulations, a universal analytical formula is derived for the lateral distribution of light in the shower image and a correction factor is obtained to account for the fraction of shower light falling into outlying pixels in the detector. The expected light profiles and the corresponding correction of the primary shower energy are illustrated for several typical event geometries. This correction of the shower energy can exceed 10%, depending on shower geometry.

description: We study the equation of state of neutron matter at finite temperature based on two- and three-nucleon interactions derived within chiral effective field theory to next-to-next-to-next-to-leading order. The free energy, pressure, entropy, and internal energy are calculated using many-body perturbation theory including terms up to third order around the self-consistent Hartree-Fock solution. We include contributions from three-nucleon interactions without employing the normal-ordering approximation and provide theoretical uncertainty estimates based on an order-by-order analysis in the chiral expansion. Our results demonstrate that thermal effects can be captured remarkably well via a thermal index and a density-dependent effective mass. The presented framework provides the basis for studying the dense matter equation of state at general temperatures and proton fractions relevant for core-collapse supernovae and neutron star mergers.

description: I show that the basic structure of symplectic integrators is governed by a theorem which states {\it precisely}, how symplectic integrators with positive coefficients cannot be corrected beyond second order. All previous known results can now be derived quantitatively from this theorem. The theorem provided sharp bounds on second-order error coefficients explicitly in terms of factorization coefficients. By saturating these bounds, one can derive fourth-order algorithms analytically with arbitrary numbers of operators.

description: The Short-Time Fourier Transform (STFT) has been a staple of signal processing, often being the first step for many audio tasks. A very familiar process when using the STFT is the search for the best STFT parameters, as they often have significant side effects if chosen poorly. These parameters are often defined in terms of an integer number of samples, which makes their optimization non-trivial. In this paper we show an approach that allows us to obtain a gradient for STFT parameters with respect to arbitrary cost functions, and thus enable the ability to employ gradient descent optimization of quantities like the STFT window length, or the STFT hop size. We do so for parameter values that stay constant throughout an input, but also for cases where these parameters have to dynamically change over time to accommodate varying signal characteristics.

description: This paper shows how job search success, measured as search duration and entry salary, is affected directly or indirectly by personal and process as well as structural characteristics. A specific focus is on the relevance of practical experience which is claimed to be a key feature of employability. While self-assessed practical and namely international experience is positively related to salary, but not to search duration, the number and duration of internships does not affect job search success. Results are relevant for higher education institutions to develop their curricula, for students to prepare for job search, and for employers to understand the genesis of employability and their potential means to impact it.

description: Generalizing earlier results on dust collapse in higher dimensions, we show here that cosmic censorship can be restored in gravitational collapse with tangential pressure present if we take the spacetime dimension to be $N\ge6$. This is under conditions to be motivated physically, such as the smoothness of initial data from which the collapse develops. The models considered here incorporating a non-zero tangential pressure include the Einstein cluster spacetime.

description: In the model suggested by Smilansky one studies an operator describing the interaction between a quantum graph and a system of K one-dimensional oscillators attached at different points of the graph. This paper is a continuation of our investigation of the case K>1. For the sake of simplicity we consider K=2, but our argument applies to the general situation. In this second paper we apply the variational approach to the study of the point spectrum.

title: Competitive Analysis for Incremental Maximization
Creators: name: Weckbecker, David Michael
Publisher: name: UNSPECIFIED
Year: 2024

description: In incremental maximization, we are tasked with building up a solution over time by adding elements from a groundset one by one. We want to maximize the monotone objective value of the assembled solution. However, the information how many elements may be added to the final solution is only revealed when the last feasible element is added. Thus, the goal is to give an ordering in which to add the elements such that the value of the solution in each step is maximized. In this thesis, we investigate this problem in the sense of competitive analysis and present upper and lower bounds on the competitive ratio for various subclasses of this problem.

We prove bounds on the competitive ratio of the greedy algorithm for a broad class of objective functions that unifies several well-known classes from the literature. Beyond the greedy algorithm, we analyze multiple scaling algorithms for the problem setting with an accountable objective and give tight bounds on their competitive ratios. In order to further improve the competitive ratio, we introduce a randomized variant of a scaling algorithm and prove bounds on the randomized competitive ratio of incremental maximization with an accountable objective. We introduce a continuization technique and use it to show an improved lower bound on the competitive ratio of incremental maximization with an accountable objective function. In an attempt to capture more objective functions than only accountable ones, we relax this property and show bounds on the competitive ratio if the objective is beta-accountable. This new class captures objectives as, for example, subadditive ones. Lastly, we generalize the incremental maximization problem by considering an unknown knapsack constraint instead of an unknown cardinality constraint. We prove bounds on the strict and non-strict competitive ratio of this problem if the objective function is fractionally subadditive.

description: Purpose_The goal of this paper is to explore the possible synergetic effects between lean philosophy and green endeavors in improving resource efficiency in the food sector. To that end, it is investigated how a proper and tailor-made adaptation of the lean six sigma root cause analysis method could help in overcoming the complexities of increased resource efficiency in food production.
Design/methodology/approach_The case study concerned reduction of waste at an industrial production line of a dough-based product, through the implementation of the lean six sigma tool.
Findings_An achievement of a 50% reduction of waste on the studied process line was reached, thus exceeding the initial improvement goal.
Research limitations/implications (if applicable)_While the explicit findings on the specific root causes of waste on this actual production line are not immediately transferrable to other cases, they show that applying this method to identifying and eliminating root causes of waste for other products and processes in the food sector could not only reduce costs but also contribute to more resource-efficient and sustainable industrial food production.
Practical implications (if applicable)_ Political and public high interest in environmental and social sustainability associated with food waste render this an important development.
Originality/value_ While the potential of linking green and lean efforts has been acknowledged, the application of the lean six sigma methodology for more sustainable food production has not yet been explored. This paper contributes to this research

Subjects: biofuels; decision support system; investmen; analysis; UML

description: In the short and medium terms, biofuels are the most viable alternative to reduce the environmental impact of fossil fuels. The recent controversy over the competition between biofuels and food production increases the complexity of investment decisions in the biodiesel production chain. In this context, decision support tools are highly relevant. The purpose of this article is to describe the BiodieselFAO using the Unified Modeling Language (UML). An integrated analysis considering both agricultural and industrial sectors was identified as a key requirement to the system. Therefore, farmers and industry are the main actors in the use case diagram. As the raw material represents around 70% of the industrial cost of biodiesel production, the price negotiation of raw material (oilseeds) is the central use case. Configuration, agriculture, industry, results and scenarios are the modules, which encompass the functionalities derived from the UML diagrams. The Food and Agriculture Organization of the United Nations (FAO) has made the BiodieselFAO available, free of charge, to around 180 professionals from 17 Latin American countries. Additionally, the developing team has supported the usage of the BiodieselFAO in several biodiesel investment analyses throughout Latin America. The system was also useful in the design and analysis of policy related to biodiesel industry in Brazil.

description: The success of various bank management strategies is evaluated using data from banks located in Minnesota during 1988-1994. These strategies are identified using a combination of data from financial statements and survey data. Each strategy is evaluated based on its effect on rate of return on assets and rate of return on equity. The study finds that cost containment strategies are relatively more successful than strategies which emphasize the expansion of services. The implications for the future structure of the Minnesota banking industry are discussed.

description: Due to their anisotropy, layered materials are excellent candidates for studying the interplay between the in-plane and out-of-plane entanglement in strongly correlated systems. A relevant example is provided by 1T-TaS2, which exhibits a multifaceted electronic and magnetic scenario due to the existence of several charge density wave (CDW) configurations. It includes quantum hidden phases, superconductivity and exotic quantum spin liquid (QSL) states, which are highly dependent on the out-of-plane stacking of the CDW. In this system, the interlayer stacking of the CDW is crucial for the interpretation of the underlying electronic and magnetic phase diagram. Here, thin-layers of 1T-TaS2 are integrated in vertical van der Waals heterostructures based on few-layer graphene (FLG) contacts and their electrical transport properties are measured. Different activation energies in the conductance and a gap at the Fermi level are clearly observed. Our experimental findings are supported by fully self-consistent DFT+U calculations, which evidence the presence of an energy gap in the few-layer limit, not necessarily coming from the formation of out-of-plane spin-paired bilayers at low temperatures, as previously proposed for the bulk. These results highlight dimensionality as a key effect for understanding the properties of 1T-TaS2 and opens the door to the possible experimental realization of low-dimensional QSLs.

description: We examine the generation of a magnetic field in a solar-like star and its effects on the internal distribution of the angular velocity. We suggest that the evolution of a rotating star with magnetic fields leads to an equilibrium value of the differential rotation. This equilibrium is determined by the magnetic coupling, which favours a constant rotation profile, and meridional circulation which tends to build differential rotation. The global equilibrium stage is close to solid body rotation between about 0.7 and 0.2 R_sun, in good agreement with helioseismic measurements.

title: Radio Resource Management for Millimeter-Wave Networks: Modeling and Design
Creators: name: Abanto Leon, Luis Fernando
Publisher: name: UNSPECIFIED
Year: 2024

description: Radio resource management (RRM) plays a critical role in modern wireless communications networks. RRM 's ultimate goal is to devise strategies to efficiently manage the network's radio resources, e.g., infrastructure and spectrum, and thus coordinate interference and ensure QoS requirements for the UE. RRM has undergone a tremendous transformation from initially being limited to solely the physical layer with fixed policies to presently incorporating dynamic cross-layer algorithms that allow controlling multiple characteristics of the physical and higher layers.

Each succeeding generation of wireless mobile technology has contributed to expanding the network capabilities but has also posed new challenges for RRM in coordinating more radio spectrum, e.g., millimeter-wave spectrum, and more radio infrastructure, e.g., CoMP and IAB. Therefore, as wireless technologies evolve, RRM strategies must also adapt to account for emerging radio infrastructure and spectrum, ensuring their efficient utilization along with the existing resources.


This thesis proposes several RRM strategies and algorithms to improve radio resource utilization, addressing challenges intrinsic to the evolution of wireless mobile technologies. Different RRM research problems are investigated considering diverse radio resources, such as precoding, admission control, and discrete rate allocation, focusing on various use cases, such as Industry 4.0. 

The strategies and algorithms developed herein not only target networks deployed using SDMA, adopted as de facto multiple access scheme, but also target emerging multiple access schemes, such as LDMA and RSMA. In addition, the strategies and algorithms are not limited to access networks only, but also include backhaul networks, specifically IAB technology.

description: Biconformal gravity, based on gauging of the conformal group to 2n dimensions, reproduces n-dim scale-covariant general relativity on the co-tangent bundle in any dimension. We generalize this result to include Yang-Mills matter sources formulated as SU\left(N\right) gauge theories with a twisted action on the full 2n-dimensional biconformal space. We show that the coupling of the sources to gravity does not stop the reduction of effective dimension 2n\rightarrow n of the gravity theory, and instead forces the Yang-Mills source to reduce to ordinary n-dimensional Yang-Mills theory on the gravitating cotangent bundle, with the usual Yang-Mills energy tensor as gravitational source. The results apply as well to gravity with sources on Kähler manifolds and in double field theories.

description: We establish the universal edge scaling limit of random partitions with the infinite-parameter distribution called the Schur measure. We explore the asymptotic behavior of the wave function, which is a building block of the corresponding kernel, based on the Schr{ö}dinger-type differential equation. We show that the wave function is in general asymptotic to the Airy function and its higher-order analogs in the edge scaling limit. We construct the corresponding higher-order Airy kernel and the Tracy-Widom distribution from the wave function in the scalins limit, and discuss its implication to the multicritical phase transition in the large size matrix model. We also discuss the limit shape of random partitions through the semi-classical analysis of the wave function.
