description: Mountain regions provide essential ecosystem goods and services (EGS). Global change however endangers the capacity of mountain ecosystems to provide key services. The ‹Mountland› project is focusing on three case study regions in the Swiss Alps and aims at proposing land-use practices and alternative policy solutions to ensure the provision of EGS under climate and land-use changes. In ‹Mountland› an integrative approach is applied, com-bining methods from agricultural economics and the political and natural sciences to analyse ecosystem functioning from a holistic human-environment system perspective. In this poster paper, I give a short introduction to the project and summarize those results which are based on the socio-economic land-use model ALUAM which provided a platform for the integration of different inter- and transdisciplinary data and knowledge on a common scale.

description: We use intersection theory, degeneration techniques and jet schemes to study log canonical thresholds. Our first result gives a lower bound for the log canonical threshold of a pair in terms of the log canonical threshold of the image by a suitable smooth morphism. This in turn is based on an inequality relating the log canonical threshold and the Samuel multiplicity, generalizing our previous result from math.AG/0205171. We then give a lower bound for the log canonical threshold of an affine scheme defined by homogeneous equations of the same degree in terms of the dimension of the non log terminal locus (this part supersedes math.AG/0105113). As an application of our results, we prove the birational superrigidity of every smooth hypersurface of degree N in P^N, if 4\leq N\leq 12.

description: The numerical simulation of the time-dependent Schrödinger equation for quantum systems is a very active research topic. Yet, resolving the solution sufficiently in space and time is challenging and mandates the use of modern high-performance computing systems. While classical parallelization techniques in space can reduce the runtime per time-step, novel parallel-in-time integrators expose parallelism in the temporal domain. They work, however, not very well for wave-type problems such as the Schrödinger equation. One notable exception is the rational approximation of exponential integrators. In this paper we derive an efficient variant of this approach suitable for the complex-valued Schrödinger equation. Using the Faber-Carathéodory-Fejér approximation, this variant is already a fast serial and in particular an efficient time-parallel integrator. It can be used to augment classical parallelization in space and we show the efficiency and effectiveness of our method along the lines of two challenging, realistic examples.

description: This paper investigates the impact of labour force composition on productivity in EU arable farming. We test the heterogeneity of family and hired labour for a set of eight EU member states. To this end, we estimate augmented production functions using FADN data for the years 2001-2008. The results reject the notion that hired labour is generally less productive than family workers. In fact, hired labour is more productive than family members in countries traditionally characterised by family farms, namely France, West Germany and Poland. Here, an increase in reliance on hired labour or the shift of family labour to more productive tasks could raise productivity. This finding calls into question a main pillar of the received family farm theory. In about half the countries, there are no statistically different effects of both types of labour. For the United Kingdom, we find the classical case with family labour being more productive than hired labour. In this situation supervision by family members could increase productivity.

description: Competition between superconducting and ferromagnetic ordering at interfaces between ferromagnets (F) and superconductors (S) gives rise to several proximity effects such as odd-triplet superconductivity and spin-polarized supercurrents. A prominent example of an S/F proximity effect is the spin switch effect (SSE) observed in S/F/N/F superconducting spin-valve multilayers, in which the superconducting transition temperature T$_c$ is controlled by the angle $ϕ$ between the magnetic moments of the F layers separated by a nonmagnetic metallic spacer N. Here we present an experimental study of SSE in Nb/Co/Cu/Co/CoO$_x$ nanowires measured as a function of bias current flowing in the plane of the layers. These measurements reveal an unexpected dependence of T$_c(ϕ)$ on the bias current: T$_c(π)$--T$_c(0)$ changes sign with increasing current bias. We attribute the origin of this bias dependence of the SSE to a spin Hall current flowing perpendicular to the plane of the multilayer, which suppresses T$_c$ of the multilayer. The bias dependence of SSE can be important for hybrid F/S devices such as those used in cryogenic memory for superconducting computers as device dimensions are scaled down to the nanometer length scale.

description: We study the excitation of electron currents in a transparent cell of sub-millimeter size filled by an atomic gas and illuminated by an intense two-color femtosecond laser pulse. The pulse consists of a strong fundamental component and its second harmonic of low intensity, both circularly polarized. We show that for sufficiently small $20μ$m cells the plasma oscillation excited by asymmetric ionization is almost spatially homogeneous within the interaction volume. This coherent dipole plasma oscillation results in a remarkably efficient conversion of the electron energy into that of radiation emitted in the terahertz frequency domain. Simultaneously, strong quasi-static electric fields of maximal strength $E_m\simeq 10$MV/cm are shown to exist inside the cell during several hundred femtoseconds after the ionizing two-color laser pulse has gone.

description: Considering the scale of global warming, we make an attempt to assess the impact of climate change on Macedonian agriculture. Farmers’ adaptation is taken into account by using an alternative specification of the Ricardian model based on the use of aridity indices to capture the non-linear response of farmland values to temperature and precipitation. Econometric results indicate that winter and spring aridity indices influence unit gross returns of crop farms. A decomposition analysis of aridity indices between temperatures and precipitations results in the derivation or marginal responses of unit gross returns of crop farms to seasonal temperatures and precipitations.

description: Mesh-free methods have significant potential for simulations in complex geometries, as the time consuming process of mesh-generation is avoided. Smoothed Particle Hydrodynamics (SPH) is the most widely used mesh-free method, but suffers from a lack of consistency. High order, consistent, and local (using compact computational stencils) mesh-free methods are particularly desirable. Here we present a novel framework for generating local high order difference operators for arbitrary node distributions, referred to as the Local Anisotropic Basis Function Method (LABFM). Weights are constructed from linear sums of anisotropic basis functions (ABFs), chosen to ensure exact reproduction of polynomial fields up to a given order. The ABFs are based on a fundamental Radial Basis Function (RBF), and the choice of fundamental RBF has small effect on accuracy, but influences stability. LABFM is able to generate high order difference operators with compact computational stencils (4th order with 25 nodes, 8th order with 60 nodes in two dimensions). At domain boundaries (with incomplete support) LABFM automatically provides one-sided differences of the same order as the internal scheme, up to 4th order. We use the method to solve elliptic, parabolic and mixed hyperbolic-parabolic PDEs, showing up to 8th order convergence. The inclusion of hyperviscosity is straightforward, and can effectively provide stability when solving hyperbolic problems. LABFM is a promising new mesh-free method for the numerical solution of PDEs in complex geometries. The method is highly scalable, and for Eulerian schemes, the computational efficiency is competitive with RBF-FD for a given accuracy. A particularly attractive feature is that in the low order limit, LABFM collapses to SPH, and there is potential for Arbitrary Lagrangian-Eulerian schemes with natural adaptivity of resolution and accuracy.

description: Brazil is a continental country, with more than 8 million square kilometers and many biomes, which have permanent preservation areas and legal reserves protected by the Forest Code. On the other hand, Brazil is an agricultural country, that increasingly needs of agricultural land. In 2012 after much controversy approved the new Brazilian Forest Code. The article, then, is to evaluate the changes brought by the new Forest Code and the future impact of the same on small and medium farms and the environment. We conclude that the new forest code can have serious consequences for the environment and human life.

description: The differences in development in Slovenia are still significant. In order to minimize them and to ensure sustainable development, it is necessary, for good policy planning, to understand the key factors that cause these differences. Analyses presented in this paper are a part of a larger study of economic and development performance in Slovenia. We tried to extract the key factors, using the method of principal components analysis that reduce the number of indicators to 11 new independent variables, explaining 76.5% of total variability. On the basis of principal components, municipalities were further classified into four groups that reflect different economic and development performance. In this contribution we focused more on two important factors: educational structure of population and the structure of economic activities and the differences between urban and rural municipalities. Analyses show that better educational structure of area residents has influence on better economic power of the population, stimulate entrepreneurship, innovations, investment dynamics etc. For the economic performance of the area the structure of economic activities is important as well. Areas with higher share of active population employed in services performed better as areas where the share of agricultural or industrial employment is higher.

description: L’informatrice raconte qu’après la naissance de son fils elle n’a pas pu donner le sein car celui-ci avait un problème de glycémie. L’enfant a reçu des flacons de glucoses à la naissance mélangée avec du lait maternisé au biberon. L’informatrice explique que les jours suivants, elle a commencé à donner le sein, mais son enfant n’arrivait pas à téter correctement. Elle a donc décidé de tirer son lait et de lui donner au biberon. L’informatrice se confie sur le fait de pouvoir allaiter son enfant une fois que celui-ci sera plus vigoureux. Elle évoque les conseils donnés par la puéricultrice pour tirer le lait et elle poursuit en décrivant l'habitude qu’elle a prise pour tirer son lait. L’informatrice explique qu’elle souhaite allaiter son enfant pendant environ huit mois et elle évoque la durée de son congé maternité. L’enquêtrice demande à l'informatrice quel est son point de vue concernant l'allaitement en public. La mère liste un certain nombre d’aliments qu’elle évite de consommer pour ne pas donner des maux de ventre à son enfant. L’informatrice explique les soins prodigués sur sa poitrine durant l’allaitement. L’enquêtrice demande ensuite à l'informatrice de lui parler du premier lait qu’elle a constaté après la naissance. L’informatrice précise qu’elle s'est renseigné sur l’allaitement et le lait maternel en lisant beaucoup de livres. L'informatrice raconte également les conseils que lui ont donnés les sages-femmes à la maternité ainsi que les premiers soins qui ont été donné à l’enfant à la suite de la naissance. L'informatrice décrit rapidement le colostrum, qui est appelé ici le “pré-lait”. L’informatrice évoque également l’allaitement au biberon avec du lait maternisé. La mortalité infantile notamment la “mort subite du nourrisson" est évoquée ainsi que les rapports sexuels durant la grossesse et la période d'allaitement. À la fin de l’enquête l'informatrice raconte les relations entre les parents et les enfants, et se confie sur sa préparation avant l’accouchement (cours de yoga, cours préparatoires à la naissance).

description: Including polynomials with small degree and stencil when designing very high order reconstructions is surely beneficial for their non oscillatory properties, but may bring loss of accuracy on smooth data unless special care is exerted. In this paper we address this issue with a new Central WENOZ (CWENOZ) approach, in which the reconstruction polynomial is computed from a single set of non linear weights, but the linear weights of the polynomials with very low degree (compared to the final desired accuracy) are infinitesimal with respect to the grid size. After proving general results that guide the choice of the CWENOZ parameters, we study a concrete example of a reconstruction that blends polynomials of degree six, four and two, mimicking already published Adaptive Order WENO reconstructions [Balsara, Garain and Shu, J.Comput.Phys., 2016], [Arbogast, Huang and Zhao, SIAM J.Numer.Anal., 2018]. The novel reconstruction yields similar accuracy and oscillations with respect to the previous ones, but saves up to 20% computational time since it does not rely on a hierarchic approach and thus does not compute multiple sets of nonlinear weights in each cell.

description: The spin structure functions of the system of quasifree fermions on mass shell are studied in a consistently covariant approach. Comparison with the basic formulas following from the quark-parton model reveals the importance of the fermion motion inside the target for the correct evaluation of the spin structure functions. In particular it is shown, that regarding the moment $Γ_{1}$, both the approaches are equivalent for the static fermions, but differ by the factor 1/3 in the limit of massles fermions ($% m \ll p_0$, in target rest frame). Some other sum rules are discussed as well.

description: Error estimates on parton density distributions are presently based on the traditional method of least squares minimisation and linear error propagation in global QCD fits. We review the underlying assumptions and the various mathematical representations of the method and address some technical issues encountered in such a global analysis. Parton distribution sets which contain error information are described.

description: It is intuitively imagined that the energy of a classical object always takes continues values and can hardly be confined to discrete ones like the energy levels of microscopic systems. Here, we demonstrate that such classical energy levels against intuition can be created through a previously unknown synchronization process for nonlinearly coupled macroscopic oscillators driven by two equally strong fields. Given the properly matched frequencies of the two drive fields, the amplitude and phase of an oscillator will be frozen on one of a series of determined trajectories like energy levels, and the phenomenon exists for whatever drive intensity beyond a threshold. Interestingly, the oscillator's motion can be highly sensitive to its initial condition but, unlike the aperiodicity in chaotic motion, it will nonetheless end up on such fixed energy levels. Upon reaching the stability, however, the oscillations on the energy levels are robust against noisy perturbation.

description: In the period leading up to the start of the Margin Protection Program for Dairy Producers (MPP-Dairy), a survey was undertaken to assess dairy farmer knowledge, attitudes, impressions and expected participation decisions. All surveys were collected in July and August 2014. There are six main conclusions of the survey. First, prior to the announcement of USDA rules regarding MPP-Dairy, most dairy producers felt they had ‘some knowledge’ of the program, with close to 30 percent declaring ‘no knowledge’ about the program. Second, about thirty percent of respondents had somewhat or very favorable impressions of MPP-Dairy while similar percent had somewhat or very unfavorable. Top four concerns about the program were too much government involvement, program complexity, lack of supply management and fear that the program would distort market signals to farmers. Third, close to 40 percent of producers indicated they were leaning towards registering for MPP-Dairy, while 30 percent were leaning against participation. Over 30 percent of producers had not decided if they would to participate or not. More knowledge about MPP-Dairy was associated with higher likelihood of participation. Fourth, we asked dairy farmers which coverage level they would choose in most years. Distribution of responses had two pronounced peaks, with $4.00/cwt and $6.00/cwt chosen by 28 and 25 percent of producers respectively. No other coverage choice was chosen by more than 12 percent of producers. Fifth, just under 70 percent of LGM-Dairy users indicated that when faced with a one-time irreversible choice between LGM-Dairy and MPP-Dairy, they would choose MPP-Dairy. Finally, just under 25 percent of producers indicated MPP-Dairy would ‘somewhat’ reduce their use of other risk management tools, while 18 percent replied they expected a ‘strong reduction’ in their use of other risk management instruments.

description: Data from the 2010 Agricultural Resource Management Survey (ARMS) and ERS cost of production accounts present a snapshot of the production costs, production practices, and characteristics related to U.S. corn production in 2010. This study found considerable variation in the operating and ownership costs for corn, ranging from an average of $1.74 per bushel for low-cost producers to $3.88 per bushel for high-cost producers. In 2010, high corn prices meant that most producers covered their corn production costs from harvest-month prices. The Heartland continues to be the major corn production region with the lowest operating and ownership costs per bushel, mainly because of the region’s high corn yields. The operating and ownership costs per bushel did not vary significantly by enterprise size where size is measured by the number of planted corn acres per farm. However, these costs per planted acre were lowest for farms with the smallest corn enterprises and highest for farms with the largest corn enterprises. Production value less operating and ownership costs per acre from organic corn production was higher than that from conventional corn production because higher prices more than offset lower yields for organic corn.

FCNC-free multi-Higgs-doublet models from broken family symmetries

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We demonstrate how residual flavour symmetries, infrared signatures of symmetry breaking in complete models of flavour, can naturally forbid (or limit in a flavour specific way) flavour-changing neutral currents (FCNC) in multi-Higgs-doublet models (MHDM) without using mass hierarchies. We first review how this model-independent mechanism can control the fermionic mixing patterns of the Standard Model, and then implement the symmetries in the Yukawa sector of MHDM, which allows us to intimately connect the predictivity of a given flavour model with its ability to sequester FCNC. Finally, after discussing various subtleties of the approach, we sketch an $A_4$ toy model that realises an explicit example of these simplified constructions.

description: We describe a variety of symplectic surgeries (not a priori compatible with Kahler structures) which are obtained by combining local Kahler degenerations and resolutions of singularities. The effect of the surgeries is to replace configurations of Lagrangian spheres with symplectic submanifolds. We discuss several examples in detail, relating them to existence questions for symplectic manifolds with $c_1>0, c_1=0, c_1<0$ in four and six dimensions.

description: Assuming that the hard gamma-ray emission of Cen A is a result of synchrotron radiation of ultra-relativistic electrons, we derive a lower bound on the local extragalactic magnetic field, $B> 10^{-8}$ G. This result is consistent with (and close to) upper bounds on magnetic fields derived from consideration of cosmic microwave background distortions and Faraday rotation measurements.

description: In the United States, climate change is likely to increase average daily temperatures and the frequency of heat waves, which can reduce meat and milk production in animals. Methods that livestock producers use to mitigate thermal stress—including modifications to animal management or housing—tend to increase production costs and capital expenditures. Dairy cows are particularly sensitive to heat stress, and the dairy sector has been estimated to bear over half of the costs of current heat stress to the livestock industry. In this report, we use operation-level economic data coupled with finely scaled climate data to estimate how the local thermal environment affects U.S. dairies’ effectiveness at producing outputs with a given level of inputs. We use this information to estimate the potential decline in milk production in 2030 resulting from climate change-induced heat stress. For four climate model scenarios, the results indicate modest heat stress-related production declines over the next 20 years, with the largest declines occurring in the South.
Distortion Effects of Export Quota Policy: an Analysis of the China - Raw Materials Dispute

description: The China - Raw Materials dispute recently arbitrated by the WTO opposed China as defendant to the US, the EU and Mexico as claimants on the somewhat unusual issue of export restrictions on natural resources. For the claimants, Chinese export restrictions on various raw materials, of which the country is a major producer, create shortages in foreign markets increasing the prices of these goods. China defends export limitations by presenting them as a natural resource conserving policy. This paper offers a theoretical analysis of the dispute with the help of a model of a monopoly extracting a non-renewable resource and selling it on both the domestic and foreign markets. The theoretical results focus on the effects of imposing an export quota on quantities, prices and price distortion. Given the crucial importance of demand elasticity in this theoretical understanding of the conflict, the empirical part of the paper provides estimates of import demand elasticity of the parties for each product concerned in the case. The model and the empirical results challenge the ideas that an export quota always favours conservation of natural resource, that a higher foreign price necessarily follows this policy and that it inherently increases price distortion and therefore discrimination.
