description: We investigate the thermal counterflow of the superfluid $^4$He by numerically simulating three-dimensional fully coupled dynamics of the two fluids, namely quantized vortices and a normal fluid. We analyze the velocity fluctuations of the laminar normal fluid arising from the mutual friction with the quantum turbulence of the superfluid component. The streamwise fluctuations exhibit higher intensity and longer-range autocorrelation, as compared to transverse ones. The anomalous fluctuations are consistent with visualization experiments [Mastracci et al., Phys. Rev. Fluids, Vol. 4, 083305 (2019)], and our results confirm their analysis with simple models on the anisotropic fluctuations. This success validates the model of the fully coupled dynamics and paves the way for solving some outstanding problems in this two-fluid system.

Bottom-Tau Unification in SUSY SU(5) GUT and Constraints from b to s gamma and Muon g-2

description: An analysis is made on bottom-tau Yukawa unification in supersymmetric (SUSY) SU(5) grand unified theory (GUT) in the framework of minimal supergravity, in which the parameter space is restricted by some experimental constraints including Br(b to s gamma) and muon g-2. The bottom-tau unification can be accommodated to the measured branching ratio Br(b to s gamma) if superparticle masses are relatively heavy and higgsino mass parameter μis negative. On the other hand, if we take the latest muon g-2 data to require positive SUSY contributions, then wrong-sign threshold corrections at SUSY scale upset the Yukawa unification with more than 20 percent discrepancy. It has to be compensated by superheavy threshold corrections around the GUT scale, which constrains models of flavor in SUSY GUT. A pattern of the superparticle masses preferred by the three requirements is also commented.

description: We present a novel derivation of the original Levitov formula, for the statistics of charge transported between electron reservoirs. This is done by proving a trace formula, which relates certain traces in Fock space to single particle determinants. Using the present approach we find in addition several generalizations, such as a corresponding formula for Bosons.

description: One potential tool fertilizer dealers and producers have to protect themselves against fertilizer price risk is the fertilizer swaps market. Swaps usually settle using a floating variable price that is determined by an index of cash prices. This paper calculates hedge ratios and hedging effectiveness of urea and DAP (diammonium phosphate) swaps that settle using The Fertilizer Index with various spot price locations from the United States and internationally. Results show that urea and DAP swaps that settle using The Fertilizer Index perform poorly as a hedging tool over short time periods. As the hedging horizon increases, the hedging effectiveness of swaps improves.

description: In neutrino experiments, hemispherical photomultiplier tubes (PMTs) are often used to cover large surfaces or volumes to maximize the photocathode coverage with a minimum number of channels. Instrumentation is often coarse, and neutrino event reconstruction and particle identification (PID) is usually done through the morphology of PMT hits. In future neutrino experiments, it may be desirable to perform PID from a few hits, or even a single hit, by utilizing pulse shape information. In this report, we study the principle of pulse shape PID using a single 10-inch hemispherical PMT in a spherical glass housing for future neutrino telescopes. We use the Fermilab Test Beam Facility (FTBF) MTest beamline to demonstrate that with pulse shape PID, statistical separation is possible to distinguish 2 GeV electrons from 8 GeV pions, where the total charge deposition is ~20 PE in our setup. Such techniques can be applied to future neutrino telescopes focusing on low energy physics, including the IceCube-Upgrade.

description: Domestic dogs have been central to life in the North American Arctic for millennia. The ancestors of the Inuit were the first to introduce the widespread usage of dog sledge transportation technology to the Americas, but whether the Inuit adopted local Paleo-Inuit dogs or introduced a new dog population to the region remains unknown. To test these hypotheses, we generated mitochondrial DNA and geometric morphometric data of skull and dental elements from a total of 922 North American Arctic dogs and wolves spanning over 4500 years. Our analyses revealed that dogs from Inuit sites dating from 2000 BP possess morphological and genetic signatures that distinguish them from earlier Paleo-Inuit dogs, and identified a novel mitochondrial clade in eastern Siberia and Alaska. The genetic legacy of these Inuit dogs survives today in modern Arctic sledge dogs despite phenotypic differences between archaeological and modern Arctic dogs. Together, our data reveal that Inuit dogs derive from a secondary pre-contact migration of dogs distinct from Paleo-Inuit dogs, and most likely aided the Inuit expansion across the North American Arctic beginning around 1000 BP.

description: Summary : This study summarizes cost estimates based on the EU Farm Accountancy Data Network using the General Cost of Production Model, developed, applied and tested within the FACEPA project. Results are provided for wheat, pigs and milk for the main producer countries of the EU for the period 1999 to 2007. Estimated input-output coefficients are generally based on monetary figures, expressing cost shares referring to total output. Effects of scale, specialization and location can be derived by estimates based on respective sub-samples. Costs per unit are derived based on input-output coefficients and output values, providing costs per hectare or ton for wheat and per ton of milk. There is a considerable variation between Member States not only of production costs, but also of output, and output plus subsidies (due to the national implementations of full or partially decoupling schemes), especially for wheat and milk. ------------------------------------------------------------------------------------------ Zusammenfassung: In dieser Studie werden Schätzungen von Produktionskosten basierend auf EU-Testbetriebsdaten unter Verwendung eines in dem EU-Forschungsprojekt FACEPA entwickelten Modells durchgeführt. Ergebnisse werden bereitgestellt für Weizen, Milch sowie für Schweine für die Hauptproduktionsländer der EU und für den Zeitraum 1999 bis 2007. Die geschätzten Input-Output Koeffizienten drücken die durchschnittlichen Kostenteile zum monetären Output des zugrundeliegenden Samples dar. Einflussfaktoren auf die Kosten wie Betriebsgröße, Standort und Spezialisierung können mittels Schätzung auf Basis entsprechend geschichteter Samples analysiert werden. Die Kosten je Einheit werden basierend auf den Schätzkoeffizienten und Outputs abgeleitet, und zwar je Hektar (für Weizen) sowie je Tonne für Weizen und Milch. Zwischen den Mitgliedstaaten bestehen erhebliche Unterschiede sowohl bei den Produktionskosten, dem monetären Output als auch den gekoppelten Direktzahlungen vor allem für Weizen und Milch.

description: Agricultural workers in most states are exempt from some labor law provisions that apply to employees in most other workplaces. In New York State agricultural labor advocates and farmers have battled politically over this issue for more than four decades. Two of the most contentious issues are collective bargaining and overtime pay. Currently laws for most other workers grant rights to employees who engage in union organizing activities. In addition, most employers are required to pay an overtime rate of time and one half for hours worked over 40 per week. In New York, labor advocates would like to see both of these exemptions for agriculture removed. Eleven states in the United States have laws that protect agricultural workers who wish to engage in collective bargaining and union organizing activities. In addition, four states have overtime pay provisions for agricultural workers. Introduced in the New York State Legislature in 2009, the Farmworkers Fair Labor Practices Act would have provided farmworkers with collective bargaining rights and overtime pay. It also contained other provisions viewed as having less impact on the agricultural industry. The proposal reignited a contentious debate and political standoff between farm business interests and the state’s labor advocates. The bill passed the Assembly on June 8, 2009. Leaders in the Senate had difficulty getting the bill to the Senate floor for a vote. Finally, as part of the 2010 state budget battle, Senator Pedro Espada, Senate Majority Leader, was successful in bringing about a vote. The legislation was defeated by a margin of three votes. Seldom has farmworker rights legislation gotten so close to passing both houses of the New York State Legislature with the prospect the Governor would sign it. The future prospects for overtime pay and collective bargaining rights for New York’s agricultural workers will continue to be dependent upon which political party controls the State Senate. The November 2010 elections resulted in the Republican Party recapturing the Senate majority making it unlikely that legislation similar to the Farmworkers Fair Labor Practices Act will be enacted in the near future. Both sides are extremely well organized and it appears possible this standoff could continue for many more years

description: The effective QCD Hamiltonian is constructed with the help of the background perturbation theory, and relativistic Feynman--Schwinger path integrals for Green's functions. The resulting spectrum displays mass gaps of the order of one GeV, when additional valence gluon is added to the bound state. Mixing between meson, hybrid, and glueball states is defined in two ways: through generalized Green's functions and via modified Feynman diagram technic giving similar answers. Results for mixing matrix elements are numerically not large (around 0.1 GeV) and agree with earlier analytic estimates and lattice simulations.

description: Interferometric gravitational-wave detectors like LIGO need to be able to measure changes in their arm lengths of order $10^{-18}~$m or smaller. This requires very high laser power in order to raise the signal above shot noise. One significant limitation to increased laser power is an opto-mechanical interaction between the laser field and the detector's test masses that can form an unstable feedback loop. Such parametric instabilities have long been studied as a limiting effect at high power, and were first observed to occur in LIGO in 2014. Since then, passive and active means have been used to avoid these instabilities, though at power levels well below the final design value. Here we report on the successful implementation of tuned, passive dampers to tame parametric instabilities in LIGO. These dampers are applied directly to all interferometer test masses to reduce the quality factors of their internal vibrational modes, while adding a negligible amount of noise to the gravitational-wave output. In accordance with our model, the measured mode quality factors have been reduced by at least a factor of ten with no visible increase in the interferometer's thermal noise level. We project that these dampers should remove most of the parametric instabilities in LIGO when operating at full power, while limiting the concomitant increase in thermal noise to approximately 1%.

description: To contrast different generators for flow equations for Hamiltonians and to discuss the dependence of physical quantities on unitarily equivalent, but effectively different initial Hamiltonians, a numerically solvable model is considered which is structurally similar to impurity models. By this we discuss the question of optimization for the first time. A general truncation scheme is established that produces good results for the Hamiltonian flow as well as for the operator flow. Nevertheless, it is also pointed out that a systematic and feasible scheme for the operator flow on the operator level is missing. For this, an explicit analysis of the operator flow is given for the first time. We observe that truncation of the series of the observable flow after the linear or bilinear terms does not yield satisfactory results for the entire parameter regime as - especially close to resonances - even high orders of the exact series expansion carry considerable weight.

description: A three-step procedure is proposed in type IIA string theory to stabilize multiple moduli in a dS vacuum. The first step is to construct a progenitor model with a localized stable supersymmetric Minkowski vacuum, or a discrete set of such vacua. It can be done, for example, using two non-perturbative exponents in the superpotential for each modulus, as in the KL model. A large set of supersymmetric Minkowski vacua with strongly stabilized moduli is protected by a theorem on stability of these vacua in absence of flat directions. The second step involves a parametrically small downshift to a supersymmetric AdS vacuum, which can be achieved by a small change of the superpotential. The third step is an uplift to a dS vacuum with a positive cosmological constant using the $\overline {D6}$-brane contribution. Stability of the resulting dS vacuum is inherited from the stability of the original supersymmetric Minkowski vacuum if the supersymmetry breaking in dS vacuum is parametrically small.

description: The numerical solutions of the non-linear evolution equation are shown to display the ``geometric'' scaling recently discovered in the experimental data. The phenomena hold both for proton and nucleus targets for all $x$ below $10^{-2}$ and $0.25 {\rm GeV^{2}}\le Q^2 \le 2.5\times10^3 {\rm GeV^{2}}$. The scaling is practically exact (few percent error) in the saturation region. In addition, an approximate scaling is found in the validity domain of the linear evolution where it holds with about 10% accuracy. Basing on the scaling phenomena we determine the saturation scale $Q_s(x)$ and study both its $x$-dependence and the atomic number dependence for the nuclei.

description: Over the past three years Italy has witnessed a rapid growth in the photovoltaic energy market, followed by an equally sudden decline when the government decided to reduce the incentives. This sharp change in the trend of the market calls into question the achievement of Grid Parity and the possibility that the market is able to develop independently. Starting from the standard Grid Parity Model, widely used for the photovoltaic (PV) market, we internalize the uncertainty surrounding both the energy price and PV module costs, to forecast the dynamics of the Italian PV market. We show that these sources of uncertainty can delay the Grid Parity timing of several years compared to current forecasts, well describing the current market situation.

description: This paper analyzes the challenges and opportunities for agricultural marketing cooperatives in value-added, quality-differentiated markets. Product quality in all of its dimensions is critical in modern food markets, but various traditional cooperative business practices are not conducive to success in meeting consumers’ demands for quality. We discuss and evaluate these limitations, which have led to pessimism on the part of some commentators regarding the future of cooperatives, but we also demonstrate advantages, relative to investor-owned firms inherent in some traditional coop practices, such as revenue pooling. We also propose and illustrate appropriate modeling frameworks to study cooperatives’ performance in differentiated-product market settings, including comparing the performance of open- and closed-membership cooperatives in competition with an investor-owned firm in a market with horizontal product differentiation.
Helicity conservation in inclusive nonleptonic decay B to VX: Test of long-distance final state interaction

description: The polarization measurement in the inclusive B decay provides us with a simple test of how much the long-distance final-state interaction takes place as the energy of the observed meson varies in the final state. We give the expectation of the perturbative QCD for the energy dependence of the helicity fractions in a semiquantitative form. Experiment will tell us for which decay processes the perturbative calculation should be applicable.

description: The E12-14-012 experiment performed at Jefferson Lab Hall A has collected inclusive electron-scattering data for different targets at the kinematics corresponding to beam energy 2.222 GeV and scattering angle 15.54 deg. Here we present a comprehensive analysis of the collected data and compare the double-differential cross sections for inclusive scattering of electrons, extracted using solid targets (aluminum, carbon, and titanium) and a closed argon-gas cell. The data extend over broad range of energy transfer, where quasielastic interaction, Delta-resonance excitation, and inelastic scattering yield contributions to the cross section. The double-differential cross sections are reported with high precision (~3%) for all targets over the covered kinematic range.

description: The application of k_t-factorization supplemented with the CCFM small-x evolution equation to heavy quark production at the TEVATRON and at HERA is discussed. The bb_bar production cross sections at the TEVATRON can be consistently described using the k_t-factorization formalism together with the unintegrated gluon density obtained within the CCFM evolution approach from a fit to HERA F_2 data. Special attention is drawn to the comparison with measured visible cross sections, which are compared to the hadron level Monte Carlo generator CASCADE

description: The inverse relationship between farm size and productivity has almost become a 'stylised fact' in the economic development literature. Most of the studies contributing to this preception have been flawed by methodological shortcomings and the request is that these studies be treated with caution. Using recent farm survey data from the wine producing areas of the Western Cape of South Africa, this study attempts to overcome some of the methodological problems, distinguishing between partial and total productivity measures. Using data envelopment analysis, most of the wine grape producers were found to operate under constant returns to scale. Co-operative membership seemed to overcome the economies of scale associated with processing and marketing. The inverse relationship between farm size and both land productivity and total factor productivity is weak, not consistently negative and differs between regions. Thus, caution must be used when advocating rural development policies based on the inevitability of an inverse relationship existing in all sectors and production regions of agriculture. © 1998 Elsevier Science B.V.

description: This paper develops a spatial conjunctive use model of an irrigation project in which the regulatory agency determines investments in the centralized distribution system and farmers decide the level of on-farm technology in the field. Irrigation return flows are assumed to recharge the groundwater aquifer. It is shown that there is specialization in production with upstream farmers using surface water and downstream farmers pumping from the aquifer. An empirical model suggests that the proportion of return flows has a significant effect on the level of investments in water distribution as well as in the field. For example, if return flows are relatively high, it may be optimal to allow for significant water losses from the canal and the fields. It suggests that the project pricing and technology adoption policies may need to be tempered by consideration of the basinwide impacts of water diversions. © 1998 Elsevier Science B.V.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Heat bath Monte Carlo simulations have been used to study a four-state clock model with a type of random field on simple cubic lattices. The model has the standard nonrandom two-spin exchange term with coupling energy $J$ and a random field which consists of adding an energy $D$ to one of the four spin states, chosen randomly at each site. This Ashkin-Teller-like model does not separate; the two random-field Ising model components are coupled. When $D / J = 3$, the ground states of the model remain fully aligned. When $D / J \ge 4$, a different type of ground state is found, in which the occupation of two of the four spin states is close to 50%, and the other two are nearly absent. This means that one of the Ising components is almost completely ordered, while the other one has only short-range correlations. A large peak in the structure factor $S (k)$ appears at small $k$ for temperatures well above the transition to long-range order, and the appearance of this peak is associated with slow, "glassy" dynamics. The phase transition into the state where one Ising component is long-range ordered appears to be first order, but the latent heat is very small.

description: The problems caused by water scarcity demand important changes in the criteria and objectives of water policies. The agricultural sector in Spain consumes up to 80% of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at the core of the country's national water policy. One alternative would be to resort to water pricing policies with the aim of providing incentives to save water consumption although it would inflict a certain degree of income losses to the farmers and raise the revenue collected by the water authorities. The objective of this research is to analyze the effect caused by the application of different water pricing policies on water demand, farmers' income and the revenue collected by the government agency. To undertake this analysis a dynamic mathematical programming model has been built that simulates farmers' behavior and their response to different water pricing scenarios. Empirical application of the model has been carried out in several irrigation districts in Spain covering varied farm regions and river basins. Results show that the effects of alternative pricing policies for irrigation water are strongly dependent on regional, structural and institutional conditions and that changing policies produce distinct consequences within the same region and water district. Thus, equivalent water charges would create widespread effects on water savings, farm income and collected government revenue across regions and districts. © 1998 Elsevier Science B.V.
