description: We show how rigidity emerges in experiments of sheared frictional granular materials by using generalizations of two methods for identifying rigid structures. Both approaches, the force-based dynamical matrix and the topology-based rigidity percolation, agree with each other and identify similar rigid structures. As the system becomes jammed, at a contact number of $z=2.4\pm 0.1$, a rigid backbone interspersed with floppy, particle-filled holes of a broad range of sizes emerges, creating a sponge-like morphology. We also find that the pressure within rigid structures always exceeds the pressure outside the rigid structures, i.e. that the backbone is load-bearing. These findings shows that it is necessary to go beyond mean-field theory to capture the physics of frictional jamming and also suggests that mechanical stability arises through arch structures and hinges at the mesoscale.

description: Gravity in five-dimensional braneworld backgrounds often exhibits problematic features, including kinetic ghosts, strong coupling, and the vDVZ discontinuity. These problems are an obstacle to producing and analyzing braneworld models with interesting and potentially observable modifications of 4d gravity. We examine these problems in a general AdS_5/AdS_4 setup with two branes and localized curvature from arbitrary brane kinetic terms. We use the interval approach and an explicit ``straight'' gauge-fixing. We compute the complete quadratic gauge-fixed effective 4d action, as well as the leading cubic order corrections. We compute the exact Green's function for gravity as seen on the brane. In the full parameter space, we exhibit the regions which avoid kinetic ghosts and tachyons. We give a general formula for the strong coupling scale, i.e. the energy scale at which the linearized treatment of gravity breaks down, for relevant regions of the parameter space. We show how the vDVZ discontinuity can be naturally but nontrivially avoided by ultralight graviton modes. We present a direct comparison of warping versus localized curvature in terms of their effects on graviton mode couplings. We exhibit the first example of DGP-like crossover behavior in a general warped setup.

On Beltrami states near black hole event horizon

description: In this article, we study Beltrami equilibria for plasmas in near the horizon of a spinning black hole, and develop a framework for constructing the magnetic field profile in the near horizon limit for Clebsch flows in the single-fluid approximation. We find that the horizon profile for the magnetic field is shown to satisfy a system of first-order coupled ODEs dependent on a boundary condition for the magnetic field. For states in which the generalized vorticity vanishes (the generalized `superconducting' plasma state), the horizon profile becomes independent of the boundary condition, and depend only on the thermal properties of the plasma. Our analysis makes use of the full form for the time-independent Ampere's law in the 3+1 formalism, generalizing earlier conclusions for the case of vanishing vorticity, namely the complete magnetic field expulsion near the equator of an axisymmetric black horizon assuming that the thermal properties of the plasma are symmetric about the equatorial plane. For the general case, we find and discuss additional conditions required for the expulsion of magnetic fields at given points on the black hole horizon. We perform a length scale analysis which indicates the emergence of two distinct length scales characterizing the magnetic field variation and strength of the Beltrami term, respectively.

description: In the international trade literature there seems to be some confusion between "openness" and "protection" measures. The aim of this paper is to bring together the "state of the art" in quantifying trade policy measures, so we focus on the extent of the protection granted by policies rather than on the degree of openness of the economy. Given the huge size of literature dealing with these issues, we limit our review as follows. On the one hand, we focus on trade policies implemented at the border: accordingly, we do not consider all the other possible public interventions influencing trade flows. On the other hand, we take into account only indexes explicitly adopting a metric expressed in a "scalar aggregate" (tariff- and quota-equivalent measures, or an index in a closed interval). We distinguish between indexes that aggregate across products (same barrier for more products) and indexes that aggregate across instruments (more barriers for the same product). Finally, in order to classify the large number of indexes covered in our review, we propose a typology based on three categories: incidence, outcome and equivalence.

description: Over the time a large number of reciprocal preferential trade agreements (RTAs) have been concluded among countries. Recently many studies have used gravity equations in order to estimate the effect of RTAs on trade flows between partners. These studies report very different estimates since they differ greatly in data sets, sample sizes and independent variables used in the analysis. So, what is the "true" impact of RTAs? This paper combines, explains and summarizes a large number of results (1827 estimates included in 85 papers), using a meta-analysis (MA) approach. Notwithstanding quite a high variability, studies consistently find a positive RTAs impact on bilateral trade: the hypothesis that there is no effect of trade agreements on trade is easily and robustly rejected at standard significance levels. We provide pooled estimates, obtained from fixed and random effects models, of the increase in bilateral trade due to RTAs. Finally, information collected on each estimate allows us to test the sensitivity of the results to alternative specifications and difference in the control variables considered.

description: In this work we discuss the place of Veneziano amplitudes (the precursor of string models) and their generalizations in the Regge theory of high energy physics scattering processes. We emphasize that mathematically such amplitudes and their extensions can be interpreted in terms of the Laplace (respectively, miultiple Laplace) transform(s) of generating function for the Ehrhart polynomial associated with some integral polytope P (specific for each scattering process). Following works by Batyrev and Hibi to each polytope P it is possible to associate another (mirror) polytope P'. For this to happen, it is nesessary to impose some conditions on P and, hence, on the generating function for P. Since each of these polytopes is in fact encodes some projective toric variety, this information is used for development of new symplectic and supersymmetric models reproducing the Veneziano amplitudes. General ideas are illustrated on classical example of the pion-pion scattering for which the existing experimental data can be naturally explained with help of mirror symmetry arguments.

description: Smart contract-enabled blockchains allow building decentralized applications in which mutually-distrusted parties can work together. Recently, oracle services emerged to provide these applications with real-world data feeds. Unfortunately, these capabilities have been used for malicious purposes under what is called criminal smart contracts. A few works explored this dark side and showed a variety of such attacks. However, none of them considered collaborative attacks against targets that reside outside the blockchain ecosystem. In this paper, we bridge this gap and introduce a smart contract-based framework that allows a sponsor to orchestrate a collaborative attack among (pseudo)anonymous attackers and reward them for that. While all previous works required a technique to quantify an attacker's individual contribution, which could be infeasible with respect to real-world targets, our framework avoids that. This is done by developing a novel scheme for trustless collaboration through betting. That is, attackers bet on an event (i.e., the attack takes place) and then work on making that event happen (i.e., perform the attack). By taking DDoS as a usecase, we formulate attackers' interaction as a game, and formally prove that these attackers will collaborate in proportion to the amount of their bets in the game's unique equilibrium. We also model our framework and its reward function as an incentive mechanism and prove that it is a strategy proof and budget-balanced one. Finally, we conduct numerical simulations to demonstrate the equilibrium behavior of our framework.

description: The existence and stability of solitons in Bose-Einstein condensates with attractive inter-atomic interactions, described by the Gross-Pitaevskii equation with a three-dimensional (3D) periodic potential, are investigated in a systematic form. We find a one-parameter family of stable 3D solitons in a certain interval of values of their norm, provided that the strength of the potential exceeds a threshold value. The minimum number of $^{7}$Li atoms in the stable solitons is 60, and the energy of the soliton at the stability threshold is $\approx 6$ recoil energies in the lattice. The respective energy-vs.-norm diagram features two cuspidal points, resulting in a typical \textit{swallowtail pattern}, which is a generic feature of 3D solitons supported by low- (2D) or fully-dimensional lattice potentials.

Hybrid metric-Palatini gravity: black holes, wormholes, singularities and instabilities

description: The hybrid metric-Palatini theory of gravity (HMPG), proposed in 2012 by T. Harko et al., is known to successfully describe both local (solar-system) and cosmological observations. We discuss static, spherically symmetric vacuum solutions of HMPG with the aid of its scalar-tensor representation. This scalar-tensor theory coincides with general relativity with a conformally coupled scalar field (which can be canonical or phantom), therefore the known solutions of this theory are re-interpreted in terms of HMPG. In particular, in the case of zero scalar field potential $V (ϕ)$, such that both Riemannian and Palatini Ricci scalars are zero, generic asymptotically flat solutions either contain naked singularities or describe traversable wormholes, and there are only special cases of black hole solutions with extremal horizons. There is also a one-parameter family of solutions with an infinite number of extremal horizons between static regions. Examples of analytical solutions with nonzero potentials $V (ϕ)$ are also described, among them black hole solutions with simple horizons which are generic but, for canonical scalars, they require (at least partly) negative potentials. With phantom scalars there are ``black universe'' solutions that lead beyond the horizon to an expanding universe instead of a singularity. Most of the solutions under consideration turn out to be unstable under scalar monopole perturbations, but some special black hole solutions are stable.

description: The paper explores an important issue in multilateral agricultural trade negotiations, namely the approach taken to reduce tariffs, simulating possible liberalization scenarios. The analysis is based on the model of the Global Trade Analysis Project (GTAP), and on the related version 6.0 database. Scenarios are run on a 2013 baseline, built by taking into account a number of events that have affected (and will further affect) world agricultural markets up to that period, focusing on the effects that are specifically attributable to further trade liberalization in the Doha Round. The policy strategies analyzed are two hypothetical liberalization scenarios in terms of market access and export competition, plus a free agricultural trade benchmark scenario. More specifically, in terms of market access we compare proportional cuts in tariffs with a Swiss-formula approach. Over the range of formula parameters considered here, we find that the impacts are not greatly influenced by the extent to which higher tariffs face bigger cuts. Results indicate that welfare gains could be reaped both by developed and developing countries, but only the possibility of inter-county compensations would allow, at least in principle, an agreement to be reached.

description: A new dynamic is identified between dark matter and nuclei. Nuclei accelerated to MeV energies by the internal potential of composite dark matter can undergo nuclear fusion. This effect arises in simple models of composite dark matter made of heavy fermions bound by a light scalar field. Cosmologies and detection prospects are explored for composites that catalyze nuclear reactions in underground detectors and stars, including bremsstrahlung radiation from nuclei scattering against electrons in hot plasma formed in the composite interior. If discovered and collected, this kind of composite dark matter could in principle serve as a ready-made, compact nuclear fusion generator.

description: The most recent EU notifications to the World Trade Organization regarding domestic support refer to the EU-15, i.e. before significant reforms of the direct payments as well as reforms of the Mediterranean products, hops, sugar, etc. that took place after 2003. We estimate the actual level of domestic support, as measured by WTO Aggregate Measure of Support (AMS), given the 2004 EU enlargement and the recent reforms of the Common agricultural policy. We then compare the different proposals for a new discipline on domestic support that were recently issued under the Doha Development Round and we assess the constraints imposed on the Common Agricultural Policy (CAP). The EU proposal prior to the 2005 Hong Kong WTO ministerial meeting involved that the EU would cut the AMS and the Overall Trade Distorting Support (OTDS) ceilings w by 70% in either case. We find that such a cut mainly consolidates under the WTO the significant changes made to EU domestic support policies since the conclusion of the Uruguay Round. However, there are some downside risks for the EU and much depends on the further negotiations on the details of the disciplines to be agreed (e.g. the base period for the OTDS reference). In addition, a 70% cut would have no freedom left for counting some potentially controversial subsidies against the AMS if needed. Accession of Bulgarian and Romania will make the constraints more binding. The ability to meet the domestic support discipline of the EU offer relies on the assumption that the market access component of the EU offer will lead to a significant reduction in the remaining AMS (particularly important in the case of fruits and vegetables). Overall, the EU proposal regarding a cut in the AMS is binding, even though it requires rather minor and sectoral changes to the CAP. Proposals that beyond the EU 'Hong Kong' offer require reforming some Common market organizations, but could be dealt with if the EU implemented a significant reform of the fruits and vegetables sector, that might give a larger degree of freedom regarding the AMS ceiling.

Imperfectly imperial : northern travel writers in a postbellum American south, 1865-1880
Creators: name: Winders, Jamie Lynn
Publisher: name: University of British Columbia
Year: 2009

description: Between the years 1865 and 1880, more travelers than in any period outside the Civil War streamed to an American South to write of the region. Through these writings, a literate Northern readership learned of a postwar South, a newly re-annexed territory of the United States. In this thesis, I argue that contextualizing these travel accounts and the region of the South itself as complicit with broader discourses of Western imperialism is a productive way to examine both the history and the places of Southern Reconstruction. Additionally, I contend that the tensions written through these travel narratives around the very ways travelers scripted Southern scenes are themselves constitutive elements of a Southern identity and history. Moving through discussions of three particular themes found throughout these postbellum travel accounts - discourses of civilization, descriptions and representations of 'nature' and landscape, and encounters with rural white poverty, this thesis examines the ways Northern travelers grappled with the South's 'double placement' within an imperial framework. Simultaneously an occupied imperial territory of the United States and part of the United States itself, a postbellum South was paradoxically situated in reference to both 'the North' and 'the nation' at large, a tension found throughout these travel writings. Through these discussions, this thesis endeavors to provide a critical engagement with textual representations of a postwar South, representations typically treated in a very superficial and quite straightforward manner. Arguing for a very different treatment of these texts, I attempt to show that situating them within an imperial framing provides a new look at old stories about Southern occupation and Reconstruction in the midnineteenth century.

description: The paper analyses the institutional dynamics surrounding common-pool resources in postsocialist Central and Eastern Europe. It is conceived in close conjunction with the case studies reported in the four preceding papers in this series. The purpose of this paper is to frame the individual case inquiries, compare the findings from the four plus two additional case studies, and relate those to broader agrarian and environmental changes in Central and Eastern Europe. The comparative assessment suggests that resource governance has shifted from the previously dominant legal and administrative state hierarchies towards markets. In addition, state power has moved from central governments towards local authorities. The waning and decentralisation of state power has caused the emergence of significant gaps between property legislation and rights-in-practice, which have been particularly stark in weak states. The discrepancy between legal texts and rights-in-practice leads to the exclusion of public and collective interests in favour of private interests in CPR management. It finds its environmental expression in the declining use of water control systems, widespread destruction of water infrastructure, and unfettered conversion of agricultural land for urban sprawl. Thus, the findings attest to the central role of distributive issues in postsocialist privatisation and suggest an additional dimension of distributive conflict: different rights and obligations associated with resources. They also suggest the need for postsocialist governments to be actively involved in the management of common-pool resources for the protection of public and collective interests.

description: The parallel annealing method is one of the promising approaches for large scale simulations as potentially scalable on any parallel architecture. We present an implementation of the algorithm on the hybrid program architecture combining CUDA and MPI. The problem is to keep all general-purpose graphics processing unit devices as busy as possible redistributing replicas and to do that efficiently. We provide details of the testing on Intel Skylake/Nvidia V100 based hardware running in parallel more than two million replicas of the Ising model sample. The results are quite optimistic because the acceleration grows toward the perfect line with the growing complexity of the simulated system.

description: Quantum many-body systems out of equilibrium can host intriguing phenomena such as transitions to exotic dynamical states. Although this emergent behaviour can be observed in experiments, its potential for technological applications is largely unexplored. Here, we investigate the impact of collective effects on quantum engines that extract mechanical work from a many-body system. Using an opto-mechanical cavity setup with an interacting atomic gas as a working fluid, we demonstrate theoretically that such engines produce work under periodic driving. The stationary cycle of the working fluid features nonequilibrium phase transitions, resulting in abrupt changes of the work output. Remarkably, we find that our many-body quantum engine operates even without periodic driving. This phenomenon occurs when its working fluid enters a phase that breaks continuous time-translation symmetry: the emergent time-crystalline phase can sustain the motion of a load generating mechanical work. Our findings pave the way for designing novel nonequilibrium quantum machines.

The Use of Irrigation Water During Transition in Bulgaria's Plovdiv Region

Year: 2002

description: The amount of water used for irrigation has sharply declined during transition in Bulgaria. Large sections of existing irrigation systems were abandoned, and the ones still in use are barely maintained. Crops such as wheat and barley have replaced more water-intensive crops, including vegetables, rice and maize. This problem has an impact on the future development of agriculture and the allocation of the country's water resources. The central argument is that land fragmentation in the wake of de-collectivization and restitution contributes to the irrigation systems' abandonment. This paper concentrates on the institutional factors, but also considers additional factors, that may have influenced the process; further, it examines the causes driving these changes and analyses their effect on irrigation. It is based upon a review of relevant legislation, as well as field work in 17 villages located in the Plovdiv region of Bulgaria. The paper concludes that, in addition to changes in large-scale market forces and weakening of the state enforcement mechanism, institutional settings have contributed to the decline of irrigation in Bulgaria.

description: Honeybee hives is a densely crowded, moist, and warm environment with many closely related individuals. In other words, it is the perfect setting for parasites to exploit. Since honeybees have survived for millions of years, it’s evident that they have figured out ways to keep the ever-present pathogens at bay. Parasitic mites and insect pest infestation in beehives colonies were carried out in Awgbu town and Nnamdi Azikiwe University, Awka. The study was to determine the effects of parasitic mites on bees, small hive beetle infestation on beehives colonies, wax moth damage on combs, and its susceptibility to their infestation. The total number of hives sampled was 30. 100 bees, 6 suspected infected honeycombs from weak and absconded hives were collected from the field study and kept in containers in the laboratory for analysis. The hives were inspected for small hive beetle, bees were examined under a light microscope for the presence of mites, and combs were cultured from egg to larvae through pupae and adults while mortality of this wax moth was recorded. 100 bees that were examined under the light microscope showed no presence of parasitic mites; 438 larvae fully grown to the last instars larvae, 150 pupated and 36 adult moths emerged; 59 small hive beetles were recorded from 30 inspected hives. Therefore, this study provided information to the beekeepers on the detrimental effects of wax moth that leads to colony collapse disorder in beehives colonies. The study opens new research areas in the field of agriculture as well as provides an authentic reference for future research on the subject matter.
CHALLENGES FOR AGRI-ENVIRONMENTAL POLICIES IN CEE COUNTRIES

description: All Central and Eastern European Countries (CEECs) have been going through a severe agricultural depression since their centrally planned economies collapsed in the early 1990s. It has now become clear that the transition process is far more complex and is likely to be much more protracted than was first expected. The agricultural policies of the Communist era resulted in considerable environmental problems, which are still present to varying degrees even after a considerable decrease in agricultural inputs during the past ten years. On the other hand, CEECs still retain a significant proportion of Europe's biodiversity. The existing low input and low intensity agriculture practised in these countries can be perceived in certain respects as an opportunity for environmental sustainability in the agricultural sector. However, in view of future EU membership and accompanying policies, the question is to what extent the requirements of environmental protection and nature conservation will be taken into account in the CEECs' policy formation. The paper presents a preliminary survey of agri-environmental problems and relevant regulations in the Central and Eastern European Countries and identifies future challenges for their agri-environmental policy formation.

Enhanced tunneling magnetoresistance in Fe|ZnSe double junctions

description: We calculate the tunneling magnetoresistance (TMR) of Fe|ZnSe|Fe|ZnSe|Fe (001) double magnetic tunnel junctions as a function of the in-between Fe layer's thickness, and compare these results with those of Fe|ZnSe|Fe simple junctions. The electronic band structures are modeled by a parametrized tight-binding Hamiltonian fitted to ab initio calculations, and the conductance is calculated within the Landauer formalism expressed in terms of Green's functions. We find that the conductances for each spin channel and the TMR strongly depend on the in-between Fe layer's thickness, and that in some cases they are enhanced with respect to simple junctions, in qualitative agreement with recent experimental studies performed on similar systems. By using a 2D double junction as a simplified system, we show that the conductance enhancement can be explained in terms of the junctions energy spectrum. These results are relevant for spintronics because they demonstrate that the TMR in double junctions can be tuned and enhanced by varying the in-between metallic layer's thickness.

Electron Transport in a Multi-Channel One-Dimensional Conductor: Molybdenum Selenide Nanowires

description: We have measured electron transport in small bundles of identical conducting Molybdenum Selenide nanowires where the number of weakly interacting one-dimensional chains ranges from 1-300. The linear conductance and current in these nanowires exhibit a power-law dependence on temperature and bias voltage respectively. The exponents governing these power laws decrease as the number of conducting channels increase. These exponents can be related to the electron-electron interaction parameter for transport in multi-channel 1-D systems with a few defects.

Light-ray operators, detectors and gravitational event shapes

description: Light-ray operators naturally arise from integrating Einstein equations at null infinity along the light-cone time. We associate light-ray operators to physical detectors on the celestial sphere and we provide explicit expressions in perturbation theory for their hard modes using the steepest descent technique. We then study their algebra in generic 4-dimensional QFTs of massless particles with integer spin, comparing with complexified Cordova-Shao algebra. For the case of gravity, the Bondi news squared term provides an extension of the ANEC operator at infinity to a shear-inclusive ANEC, which as a quantum operator gives the energy of all quanta of radiation in a particular direction on the sky. We finally provide a direct connection of the action of the shear-inclusive ANEC with detector event shapes and we study infrared-safe gravitational wave event shapes produced in the scattering of massive compact objects, computing the energy flux at infinity in the classical limit at leading order in the soft expansion.

description: We propose a framework for unifying the sl(N) Khovanov-Rozansky homology (for all N) with the knot Floer homology. We argue that this unification should be accomplished by a triply graded homology theory which categorifies the HOMFLY polynomial. Moreover, this theory should have an additional formal structure of a family of differentials. Roughly speaking, the triply graded theory by itself captures the large N behavior of the sl(N) homology, and differentials capture non-stable behavior for small N, including knot Floer homology. The differentials themselves should come from another variant of sl(N) homology, namely the deformations of it studied by Gornik, building on work of Lee. While we do not give a mathematical definition of the triply graded theory, the rich formal structure we propose is powerful enough to make many non-trivial predictions about the existing knot homologies that can then be checked directly. We include many examples where we can exhibit a likely candidate for the triply graded theory, and these demonstrate the internal consistency of our axioms. We conclude with a detailed study of torus knots, developing a picture which gives new predictions even for the original sl(2) Khovanov homology.

description: We show that one of the simplest extensions of the Standard Model, the addition of a second Higgs doublet, when combined with a dark sector singlet scalar, allows us to: $i)$ explain the long-standing anomalies in the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE (MB) while maintaining compatibility with the null result from KARMEN, $ii)$ obtain, in the process, a portal to the dark sector, and $iii)$ comfortably account for the observed value of the muon $g-2$. Three singlet neutrinos allow for an understanding of observed neutrino mass-squared differences via a Type I seesaw, with two of the lighter states participating in the interaction in both LSND and MB. We obtain very good fits to energy and angular distributions in both experiments. We explain features of the solution presented here and discuss the constraints that our model must satisfy. We also mention prospects for future tests of its particle content.

description: Previous constant-parameter demand models have estimated generic advertising elasticities for cheese to be below that for fluid milk. We relax this assumption, allowing for generic advertising response to vary over time. Cheese advertising elasticities were found below fluid milk up until the mid-1990s; average elasticities since have been similar.

description: Post-slaughter quality-based pricing of cattle is increasingly common. This quality, however, is dependent upon unobservable quality characteristics of the feeder cattle used as inputs. Through stochastic simulation we construct incentive compatible quality risk-sharing contracts based upon final grid-quality schedules that facilitate input quality sorting in the feeder cattle market.
