description: We study the XXZ Heisenberg model in a staggered magnetic field using the HOTRG tensor renormalization method. Built into the tensor representation of the XXZ model is the U(1) symmetry, which is systematically maintained at each renormalization step. We determine the phase diagram of the model from the low lying spectrum, and from the finite size dependence of the spectrum we extract scaling dimensions, which are compared to predictions of low energy field theory.

description: Positive political economy is usually concerned with economic explanations of observed policy choices, while the timing of a policy reform has not gained similar attention. This is somewhat surprising since policy makers most often are free to decide both the design and timing of a policy reform. Drawing on insights from recent developments in the finance literature on investment under uncertainty, here we apply the idea of option value to the analysis of government policy making. Common political-economic explanations of the 1992 CAP reform are that policymakers felt domestic political pressure to make the CAP more efficient, and also international political pressure and to bring the CAP in line with treaty obligations. Although these arguments are sound, they fail to explain why policy-makers did not enact the reform earlier, especially during times of decreasing world market prices prior to 1992. We address this question using the theory of option value, which is the value of being able to wait in decisionmaking. Commonly governments are free to decide when to reform policy. Waiting to reform policy can improve government decisions. For while waiting decision-makers may observe market parameter changes as they occur. (For example, they may obtain better information about changes in world prices.) This reduces their uncertainty about the effects of their decisions. Giving up the option to wait incurs a cost which has to be taken into account in policy decisions. We illustrate the option value concept using a political-economy model of the 1992 CAP reform. We show empirically that if decision-makers had not had the option to wait to reform policy, it would have been more efficient to implement the 1992 CAP reform in the mid 1980s.
Impact of Four-Quark Shape Functions on Inclusive B Decay Spectra

description: It has recently been pointed out that a new class of subleading shape functions involving B-meson matrix elements of non-local four-quark operators contributes at order Lambda_{QCD}/m_b to B->X_u+l+nu decay distributions in the endpoint region. The corresponding functions f_u(omega) and f_v(omega) are estimated using the vacuum-insertion approximation. A numerical analysis of various B->X_u+l+nu decay spectra suggests that these power corrections are very small, below present theoretical uncertainties due to other subleading shape-function contributions.

A Simple Proportional Conflict Redistribution Rule

description: One proposes a first alternative rule of combination to WAO (Weighted Average Operator) proposed recently by Josang, Daniel and Vannoorenberghe, called Proportional Conflict Redistribution rule (denoted PCR1). PCR1 and WAO are particular cases of WO (the Weighted Operator) because the conflicting mass is redistributed with respect to some weighting factors. In this first PCR rule, the proportionalization is done for each non-empty set with respect to the non-zero sum of its corresponding mass matrix - instead of its mass column average as in WAO, but the results are the same as Ph. Smets has pointed out. Also, we extend WAO (which herein gives no solution) for the degenerate case when all column sums of all non-empty sets are zero, and then the conflicting mass is transferred to the non-empty disjunctive form of all non-empty sets together; but if this disjunctive form happens to be empty, then one considers an open world (i.e. the frame of discernment might contain new hypotheses) and thus all conflicting mass is transferred to the empty set. In addition to WAO, we propose a general formula for PCR1 (WAO for non-degenerate cases).

description: This study provides one of the first detailed analyses of the impact of Fair Trade (FT) banana certification at the household level. With a careful selection of treatment and control farmers (through their associations) and the use of a propensity score matching technique, we were able to construct an appropriate counterfactual for the situation of FT farmers prior to their involvement in this supply chain. Due to the fact that all sales of banana FT in the Chira Valley also have an organic certification, and to be able to distinguish the effects of FT involvement from the effects of participating in the organic market, we compared the outcomes of organic farmers which belong to a FT association with the outcomes of two different types of farmers: (a) organic farmers which belong to an association recently FT certified, and (b) conventional farmers in the same area which do not belong to any association. Our results provide clear evidence of an impact of FT involvement on income and overall welfare indicators for banana farmers in the Chira Valley. These improvements are not only achieved via the better price obtained for FT sales but also because of higher productivity levels obtained as a results of the FT premium investment.

The properties of this twisted crossed product algebra are studied in detail, and are applied to T-duality in Type II string theory to obtain the T-dual of a general principal torus bundle with general H-flux, which we will argue to be a bundle of noncommutative, nonassociative tori. We also show that this construction of the T-dual includes all of the special cases that were previously analysed.

description: Most of the studies based on the New Empirical Industrial Organization (NEIO) approach use the industry data to estimate the degree of market power at the national level. Yet, only a few empirical studies presented the results that measure the degree of market power at the regional level and found the existence of market power in the regional markets. While the fact is that there is an extensive evidence for the existence of potential oligopsony market power in the Ukrainian milk processing industry (price cartels and geographic market sharing among milk processing enterprises, interference of the state authorities, higher concentration on regional markets), the estimation results of the market structure model at the national level did not produce any evidence suggesting the exercise of oligopsony power (the estimated parameter of oligopsony power is close to zero and statistically insignificant). The objective of this study is to estimate the degree of oligopsony power in the regional market for raw milk. The estimation results of the market structure model at the regional level indicate the existence of oligopsony power in nine out of the twenty three regions of Ukraine.

description: We formulate a new approach to solving the initial value problem of the shallow water-wave equations utilizing the famous Carrier-Greenspan transformation [G. Carrier and H. Greenspan, J. Fluid Mech. 01, 97 (1957)]. We use a Taylor series approximation to deal with the difficulty associated with the initial conditions given on a curve in the transformed space. This extends earlier solutions to waves with near shore initial conditions, large initial velocities, and in more complex U-shaped bathymetries; and allows verification of tsunami wave inundation models in a more realistic 2-D setting.

A lithogeochemical study of hydrothermal alteration associated with Mafic Hosted and Besshi-type Massive Sulphide deposits
Creators: name: Stoynov, Hristo Simeonov
Publisher: name: University of British Columbia
Year: 2009

description: Pearce element ratio (PER) analysis was proposed in 1968 as a graphical method to be applied in petrology. Using major element chemical compositions of rocks, it allows for the determination of primary mineral parageneses. The application of the technique was later expanded to include studies of hydro thermal alteration associated with mineral deposits. This study tests the applicability of PER analysis and the related generalized element ratio (GER) analysis methods to the study of alteration associated with two classes of Volcanic-Hosted Massive Sulphide deposits. Presented are case studies of the Chu Chua and the Konuto Lake Mafic-Hosted Massive Sulphide deposits and the Goldstream Besshi-type deposit. Molar element ratio techniques (PER and GER) are used to identify altered samples and to differentiate between individual chemical alteration types. It is demonstrated that the technique is capable of identifying the exact alteration reaction for an individual sample or for a coherently altered group of samples. The format in which the chemical analytical data are presented allows for a convenient interpretation of the mineralogical effects of alteration. Thus, the validity of the conclusions based on major element lithogeochemistry can be independently verified by petrographic methods. The most typical chemical alteration types found in the three studied deposits are silica mobility (loss and addition), loss of Ca and Na and addition of Fe and Mg. Mineralogically, the alteration process involves the destruction of plagioclase and pyroxene, local deposition of quartz and deposition of iron sulphides. At Chu Chua, extreme Fe-Mg addition caused the characteristic talc-magnetite assemblage whereas at Goldstream Fe and Mg-rich clays were deposited in a seafloor hydrothermal vent setting. Mobilized Ca, Na and excess Si02 were exhaled on the seafloor, giving rise to exhalative chert deposits, carbonate and clay minerals. The tested technique allows the degree of alteration to be quantified in each individual sample. The geographic coordinates of altered samples are then plotted to reveal the spatial patterns of alteration. The outlined alteration anomalies coincide spatially with the known ore bodies and are significantly larger in overall dimensions. Thus, in an exploration context, they would represent intermediate targets. The study proposes exploration parameters, which can be used in similar geologic settings.
Generalized Chaplygin gas as a unified scenario of dark matter/energy: observational constraints
Creators: name: Zhu, Zong-Hong
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Although various cosmological observations congruously suggest that our universe is dominated by two dark components, the cold dark matter without pressure and the dark energy with negative pressure, the nature and origin of these components is yet unknow. The generalized Chaplygin gas (gCg), parametrized by an equation of state, $p = -A/ρ_{\rm gCg}^α$, was recently proposed to be a candidate of the unified dark matter/energy (UDME) scenarios. In this work, we investigate some observational constraints on it. We mainly focus our attention on the constraints from recent measurements of the X-ray gas mass fractions in clusters of galaxies published by Allen et al. (2002,2003) and the dimensionless coordinate distances to type Ia supernovae and Fanaroff-Riley type IIb radio galaxies compiled by Daly and Djorgovski (2003). We obtain the confidence region on the two parameters fully characterizing gCg, $A_s \equiv A/ρ_{{\rm gCg}0}^{(1+α)}$ and $α$, from a combined analysis of these databases, where $ρ_{{\rm gCg}0}$ is the energy density of gCg at present. It is found that $A_s=0.70^{+0.16}_{-0.17}$ and $α=-0.09^{+0.54}_{-0.33}$, at a 95% confidence level, which is consistent within the errors with the standard dark matter + dark energy model, i.e., the case of $α= 0$. Particularly, the standard Chaplygin gas ($α=1$) is ruled out as a feasible UDME by the data at a 99% confidence level.

description: A general framework to describe a vast majority of biology-inspired systems is to model them as stochastic processes in which multiple couplings are in play at the same time. Molecular motors, chemical reaction networks, catalytic enzymes, and particles exchanging heat with different baths, constitute some interesting examples of such a modelization. Moreover, they usually operate out of equilibrium, being characterized by a net production of entropy, which entails a constrained efficiency. Hitherto, in order to investigate multiple processes simultaneously driving a system, all theoretical approaches deal with them independently, at a coarse-grained level, or employing a separation of time-scales. Here, we explicitly take in consideration the interplay among time-scales of different processes, and whether or not their own evolution eventually relaxes toward an equilibrium state in a given sub-space. We propose a general framework for multiple coupling, from which the well-known formulas for the entropy production can be derived, depending on the available information about each single process. Furthermore, when one of the processes does not equilibrate in its sub-space, even if much faster than all the others, it introduces a finite correction to the entropy production. We employ our framework in various simple and pedagogical examples, for which such a corrective term can be related to a typical scaling of physical quantities in play.

description: The recent observation of superconductivity in Nd$_{0.8}$Sr$_{0.2}$NiO$_2$ has raised fundamental questions about the hierarchy of the underlying electronic structure. Calculations suggest that this system falls in the Mott-Hubbard regime, rather than the charge-transfer configuration of other nickel oxides and the superconducting cuprates. Here, we use state-of-the-art, locally-resolved electron energy loss spectroscopy to directly probe the Mott-Hubbard character of Nd$_{1-x}$Sr$_x$NiO$_2$. Upon doping, we observe emergent hybridization reminiscent of the Zhang-Rice singlet via the oxygen-projected states, modification of the Nd 5$d$ states, and the systematic evolution of Ni 3$d$ hybridization and filling. These results clearly evidence the multiband nature of this system and the distinct electronic landscape for infinite-layer nickelates despite their formal similarity to the cuprates.
Blazar variability power spectra from radio up to TeV photon energies: Mrk 421 and PKS 2155-304
Creators: name: Goyal, Arti
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We present the results of the power spectral density (PSD) analysis for the blazars Mrk\,421 and PKS\,2155$-$304, using good-quality, densely sampled light curves at multiple frequencies, covering 17 decades of the electromagnetic spectrum, and variability timescales from weeks up to a decade. The data were collected from publicly available archives of observatories at radio from OVRO, optical and infrared (B, V, R, I, J, H, and K-bands), X-rays from the {\it Swift} and the {\it Rossi} X-ray Timing Explorer, high and very high energy $γ-$rays from the {\it Fermi} and Very Energetic Radiation Imaging Telescope Array System as well as the High Energy Stereoscopic System. Our results are: (1) the power-law form of the variability power spectra at radio, infra-red and optical frequencies have slopes $\sim$1.8, indicative of random-walk type noise processes; (2) the power-law form of the variability power spectra at higher frequencies, from X-rays to very high energy \,$γ$-rays, however, have slopes $\sim$1.2, suggesting a flicker noise type process; (3) there is significantly more variability power at X-rays, high and very high energy $γ$-rays on timescales $\lesssim$ 100 days, as compared to lower energies. Our results do not easily fit into a simple model, in which a single compact emission zone is dominating the radiative output of the blazars across all the timescales probed in our analysis. Instead, we argue that the frequency-dependent shape of the variability power spectra points out a more complex picture, with highly inhomogeneous outflow producing non-thermal emission over an extended, stratified volume.

description: Although the dark matter is usually assumed to be some form of elementary particle, primordial black holes (PBHs) could also provide some of it. However, various constraints restrict the possible mass windows to $10^{16}$ - $10^{17}\,$g, $10^{20}$ - $10^{24}\,$g and $10$ - $10^{3}\,M_{\odot}$. The last possibility is contentious but of special interest in view of the recent detection of black-hole mergers by LIGO/Virgo. PBHs might have important consequences and resolve various cosmological conundra even if they have only a small fraction of the dark-matter density. In particular, those larger than $10^{3}\,M_{\odot}$ could generate cosmological structures through the seed or Poisson effect, thereby alleviating some problems associated with the standard cold dark-matter scenario, and sufficiently large PBHs might provide seeds for the supermassive black holes in galactic nuclei. More exotically, the Planck-mass relics of PBH evaporations or stupendously large black holes bigger than $10^{12}\,M_{\odot}$ could provide an interesting dark component.

description: The escape from a potential well is an archetypal problem in the study of stochastic dynamical systems, representing real-world situations from chemical reactions to leaving an established home range in movement ecology. Concurrently, L{é}vy noise is a well-established approach to model systems characterized by statistical outliers and diverging higher-order moments, ranging from gene expression control to the movement patterns of animals and humans. Here, we study the problem of Lévy noise-driven escape from an almost rectangular, arctan potential well restricted by two absorbing boundaries. We unveil analogies of the observed transient dynamics to the general properties of stationary states of L{é}vy processes in single-well potentials. The first escape dynamics is shown to exhibit exponential tails. We examine the dependence of the escape on the shape parameters, steepness and height, of the arctan potential. Finally, we explore in detail the behavior of the probability densities of the first-escape time and the last-hitting point.

description: This research project aims to enhance collision detection and physical interaction capabilities in collaborative robotic arms, crucial for both traditional automation and human-robot interaction. The focus is on improving the dynamic model identification of manipulator robots, addressing the limitations of current methods that primarily emphasize inertial and kinematic parameters. By identifying and mitigating sources of uncertainty and delay, the project will develop optimized identification strategies and design trajectories that increase parameter observability. The out comes will be validated experimentally using a collaborative robot equipped with high-frequency torque sensors, ensuring safer and more responsive human-robot interactions.wissem01chiha/dynamic-identification: Identification and Calibration of Serial Collaborative Robotic Manipulators.

description: This article provides a general overview of the evolution of the European Union trade preferences with the African, Caribbean and Pacific (ACP) Countries, giving due attention to the reform of the Sugar Protocol (SP) in light of the anticipated Economic Partnership Agreements (EPAs). The EU sugar trade relationship with the ACP, as captured in both a reformed SP for ACP non–least developed countries and in the Everything-but-Arms initiative for the world’s least developed countries, is analysed and contextualized within the ongoing negotiations toward achieving EPAs, which will substitute the Lomé Convention and give a new order to EU-ACP relationships.

description: We study the effects of horizons on the entanglement harvested between two Unruh-DeWitt detectors via the use of moving mirrors with and without strict horizons. The entanglement reveals the sensitivity of the entanglement harvested to the global dynamics of the trajectories disclosing aspects of the effect that global information loss (where incoming massless scalar field modes from past null infinity cannot reach right future null infinity) has on local particle detectors. We also show that entanglement harvesting is insensitive to the sign of emitted radiation flux.

description: Excerpts from the report: This report is based on the third phase of a study of broiler marketing problems in Georgia. The first two phases dealt with the market structure, marketing practices and policies of producers and feed dealers, and the integration of production and marketing functions. This phase of the study was begun to assemble economic information relating to functions involved in broiler processing and to factors affecting efficiency of broiler processing. The study was limited primarily to actual and potential plant capacity and related use of labor and machinery. It involved, however, a consideration of practices used by processors in assembling live birds, in organizing the labor force, and in handling the processed product. This information is used to assess the overall capacity of the Georgia processing industry, to reach preliminary conclusions regarding economic costs at various levels of plant output, to study labor inputs-outputs, and to develop a useful description of processing practices that affect plant efficiency.

description: Changing consumer and market demands is an important driver behind the challenges and opportunities that are facing the agriculture and agri-food sector in Canada and that will influence the sector's profitability and competitiveness in the future. It is therefore important to understand developments in the consumer demand for agriculture and agri-food products. The report provides updated demand elasticities for fourteen food groups in Canada. The estimates are useful for conducting analysis of the changing structure of the agriculture and agri-food sector and can help quantify the impacts that changes in economic variables and policies that impact those economic variables might have.

description: High-resolution ghost image and ghost diffraction experiments are performed by using a single source of thermal-like speckle light divided by a beam splitter. Passing from the image to the diffraction result solely relies on changing the optical setup in the reference arm, while leaving untouched the object arm. The product of spatial resolutions of the ghost image and ghost diffraction experiments is shown to overcome a limit which was formerly thought to be achievable only with entangled photons.
