description: We study the heating time in periodically driven $D$-dimensional systems with interactions that decay with the distance $r$ as a power-law $1/r^α$. Using linear response theory, we show that the heating time is exponentially long as a function of the drive frequency for $α>D$. For systems that may not obey linear response theory, we use a more general Magnus-like expansion to show the existence of quasi-conserved observables, which imply exponentially long heating time, for $α>2D$. We also generalize a number of recent state-of-the-art Lieb-Robinson bounds for power-law systems from two-body interactions to $k$-body interactions and thereby obtain a longer heating time than previously established in the literature. Additionally, we conjecture that the gap between the results from the linear response theory and the Magnus-like expansion does not have physical implications, but is, rather, due to the lack of tight Lieb-Robinson bounds for power-law interactions. We show that the gap vanishes in the presence of a hypothetical, tight bound.
Thermal Pions ns Isospin Chemical Potential Effects

description: The density corrections, in terms of the isospin chemical potential $μ_I$, to the mass of the pions are investigated in the framework of the SU(2) low energy effective chiral invariant lagrangian. As a function of temperature and $μ_I =0$, the mass remains quite stable, starting to grow for very high values of $T$, confirming previous results. However, the dependence for a non-vanishing chemical potential turns out to be much more dramatic. In particular, there are interesting corrections to the mass when both effects (temperature and chemical potential) are simultaneously present. At zero temperature the $π^{\pm}$ should condensate when $μ_{I} = \mp m_π$. This is not longer valid anymore at finite $T$. The mass of the $π_0$ acquires also a non trivial dependence on $μ_I$ at finite $T$.

description: Branched polyethyleneimine (PEI) modified carbon nanoparticles (CNPs-PEI) with an average particle size of 20.1 nm were facile synthesized by hydrothermal treatment of citric acid and PEI. The PEI and oxygen-containing groups on CNPs-PEI endowed them with excellent dispersion stability in water. The tribological properties of CNPs-PEI as the water-based additives were evaluated under the four-ball mode, steel/steel contact and fixed load of 40 N by varying additive concentration. Amazingly, adding only 0.15 wt% of CNPs-PEI made the mean friction coefficient and wear volume of base liquid reduced by 53.4% and 94.9%, respectively, reflecting that the CNPs-PEI could be an effective additive of water lubrication. The wear scar surface analyses indicated that CNPs-PEI as additives promoted the formation of boundary lubrication films on the rubbing surfaces by mending and depositing effects, directly accounting for the distinguished friction-reducing, antiwear and oxidation resistance properties of CNPs-PEI.

description: Motivated by the theoretical paradox between the parity-violating gauge symmetries of the standard model and the fundamental regulator, we propose that the extension of the standard model to the high-energy region should be made by adding effective high-dimension operators whose dynamics gives an infrared scaling region, where not only the standard model appears as an asymptotic chiral-gauge theory, but also vectorlike one-particle-irreducible functions are induced to describe ``new physics''. We formulate the standard model on a lattice by introducing a right-handed neutrino and a sterile left-handed neutrino to form the high-dimension operators. Analyzing spectra and one-particle-irreducible functions induced by these high-dimension operators, we find that in the low-energy region, the parity-violating standard model is consistently defined, while the parity-conservation gauge-symmetry is restored in the high-energy region.

description: The EU Rural Development Policy framework is a result of complex interactions at different levels - European, national, regional and local. Ideally, the decision making process about its implementation should be shared by these different levels of governance. However, the implementation approaches vary between member states reflecting their individual governance models. This research examines the utilization of the ‘bottom-up’ approach for the development of visions for regional sustainability of agriculture and pathways to reach them in a model region in Central South Bulgaria – Bessaparski Hills area, which is a Natura 2000 zone, Important Bird Area and High Nature Value farmland.

description: Sustainable agriculture encompasses economic feasibility, social acceptance, and conservation of the environment. The three agricultural systems (conventional, integrated and organic) are currently in the focus of debate of sustainable agriculture. This paper presents a qualitative multi-attribute model, based on DEX-I methodology, for the assessment of sustainability of agricultural systems at a field level. The data for the implementation was based on field trial. In an overall assessment of the sustainability assessment outcomes the model ranked agricultural systems in the order: organic > integrated > conventional agricultural system. The model gives the decision makers the possibility to assess their decision.
CP Violation in a SUSY SO(10) x U(2)_{F} Model

description: We construct a model based on SUSY SO(10) combined with U(2) family symmetry including complex phases leading to CP violation. In contrast with the commonly used effective operator approach, \bar{126}-dimensional Higgs fields are utilized to construct the Yukawa sector. R-parity symmetry is thus preserved at low energies. The symmetric mass textures arising from the left-right symmetry breaking chain of SO(10) give rise to very good predictions for quark and lepton masses and mixings. The prediction for \sin 2βagrees with the current bounds from BaBar and Belle. In the neutrino sector, our predictions are in good agreement with results from atmospheric neutrino experiments. Our model favors both the LOW and QVO solutions to the solar neutrino anomaly; the matrix element for neutrinoless double beta decay is highly suppressed. The leptonic analog of the Jarlskog invariant, J_{CP}^{l}, is predicted to be of O(10^{-2}).

Equipped with newly developed tools that allow for a quantitative assessment of realism, here we revisit Hardy's paradox and argue that non-local causality is not mandatory for its solution; quantum irrealism suffices.

description: In this paper the Analytic Hierarchy Process (AHP) multicreteria evaluation method has been used to evaluate 4 different competing management options at olive plantations (Olea europaea L.) in mountain areas. All the evaluation process is integrated into a Geographical Information System (GIS) that gave possibility to allocate each of the options geographically. The results suggested that area currently occupied by conventional olive farming should be restructured as (% of area occupation): 35.8% to conventional olive farming, 23.3% to integrated olive farming, 19.1% to organic olive farming and 22.8% transformed to natural use as a Mediterranean forest in order to increase the social welfare of the society.
Condensate density and superfluid mass density of a dilute Bose gas near the condensation transition

description: We derive, through analysis of the structure of diagrammatic perturbation theory, the scaling behavior of the condensate and superfluid mass density of a dilute Bose gas just below the condensation transition. Sufficiently below the critical temperature, $T_c$, the system is governed by the mean field (Bogoliubov) description of the particle excitations. Close to $T_c$, however, mean field breaks down and the system undergoes a second order phase transition, rather than the first order transition predicted in Bogoliubov theory. Both condensation and superfluidity occur at the same critical temperature, $T_c$ and have similar scaling functions below $T_c$, but different finite size scaling at $T_c$ to leading order in the system size. Through a simple self-consistent two loop calculation we derive the critical exponent for the condensate fraction, $2β\simeq 0.66$.

description: Many rural areas in (East) Germany are characterised by declining birth rates and selective migration. Similarly, the rural economy is stagnating or even shrinking. Many communes are no more in a position to guarantee legally stipulated provisions of basic public services. In many rural areas agricultural production is the only remaining economic activity left while artisans and service providers have given up. In this contribution, it is analysed how agricultural producers in remote rural areas are affected by demographic change. In addition, it is discussed whether they already provide basic public services in their areas, or could do so in the future.

description: We study the fused currents of the deformed Virasoro algebra (DVA). By constructing a homotopy operator we show that for special values of the parameter of the algebra fused currents pairwise coincide on the cohomologies of the Felder resolution. Within the algebraic approach to lattice models these currents are known to describe neutral excitations of the solid-on-solid (SOS) models in the transfer-matrix picture. It allows us to prove the closeness of the system of excitations for a special nonunitary series of restricted SOS (RSOS) models. Though the results of the algebraic approach to lattice models were consistent with the results of other methods, the lack of such proof had been an essential gap in its construction.

description: Aims: To estimate the relationship between functional status (FS) impairment and nursing home admission (NHA) risk in Parkinson’s disease (PD) patients, and quantify the effect of advanced PD (APD) treatment on NHA risk relative to standard of care (SoC). Materials and methods: PD patients were identified in the Medicare Current Beneficiary Survey (MCBS) (1992–2010). A working definition based on the literature and clinical expert input determined APD status. A logit model estimated the relationship between FS impairment and NHA risk. The effect of levodopa-carbidopa intestinal gel (LCIG) on NHA risk relative to SoC was simulated using clinical trial data (control: optimized oral levodopa-carbidopa IR, ClinicalTrials.gov NCT00660387 and NCT0357994). Results: Non-advanced PD and APD significantly increased NHA risk when controlling for demographics (p Limitations: This study applies clinical trial results to real-world data. LCIG treatment might have a different effect on NHA risk for the nationally representative population than the effect measured in the trial. Both data sources employ different instruments to measure FS, instrument wording and study follow-up differed, which might bias our estimates. Finally, there lacks consensus on a definition of APD. The prevalence of APD in this study is high, perhaps due to the specific definition used. Conclusions: Patients with APD experience a higher risk in NHA than those with non-advanced disease. This increased risk in NHA in patients with APD is explained by greater limitations in FS. The relative reduction in risk of NHA for the APD population treated with LCIG is quantitatively similar to doubling Medicaid home care services.
Proton-antiproton annihilation into two photons at large s

Year: 2002
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Exclusive proton-antiproton annihilation into two photons can be viewed as the Compton process in the crossed channel. At large s (~10 GeV^2) and |t|,|u| s this process can be described by a generalized partonic picture, analogous to the 'soft mechanism' in wide-angle real Compton scattering. The two photons are emitted in the annihilation of a single fast quark and antiquark ('handbag graph'). The transition of the p-pbar system to a q-qbar pair through soft interactions is described by double distributions, which can be related to the timelike proton elastic form factors as well as, by crossing symmetry, to the usual quark--antiquark distributions in the nucleon. We estimate that this reaction should be observable with reasonable statistics at the proposed 1.5..15 GeV high-luminosity antiproton storage ring (HESR) at GSI.

In this study it has been chosen a multi-dimension approach of the phenomenon including environmental, economic and social dimensions. The objective of the work is to build up 30 simple indicators of the three dimensions using the only sources of EU FSS and SAPM 2010 with the aim to cluster the NUTS2 areas of EU in four level of sustainability: High, Medium-High, Medium-Low and Low. Results are shown in the synthetic map.

description: This thesis includes a collection of poems and a foreword discussing individual poems, the relationship of the poems as a collection, important themes, and concerns of craft. These poems comprise a narrative of place developed chronologically and are grounded in the context of regional storytelling and oral histories specific to Southwestern Virginia during roughly the first two thirds of the Twentieth Century.

History Has My Name examines culture, language, and geography—those things particular of place. In a larger social and cultural context this manuscript also focuses on the position of women and issues of racism within its stated time frame. The primary instinct of these poems is to depict these subjects honestly and without justification for long held insidious regional attitudes—attitudes that were and remain damaging to regional and cultural identities, and ideas regarding a national identity.

This makes it possible to construct, in a well-defined generic way, a normalized Nambu bracket which produces the correct Hamiltonian time evolution. Existence and explicit forms of pairwise compatible multi-Hamiltonian structures for any maximal superintegrable system have been established. The Calogero-Moser system, motion of a charged particle in a uniform perpendicular magnetic field and Smorodinsky-Winternitz potentials are considered as illustrative applications and their symmetry algebras as well as their Nambu formulations and alternative Poisson structures are presented.

We find that the nuclear medium enhanced power corrections at order of $O(α_s/Q^2)$ enhance the longitudinal structure function $F_L$, and suppress the transverse structure function $F_1$. We demonstrate that strong nuclear effects in $σ_A/σ_D$ and $R_A/R_D$, recently observed by HERMES Collaboration, can be explained in terms of the nuclear enhanced power corrections.

description: A national policy of the Republic of Serbia bases on a membership in the European Union (EU) and the World Trade Organization (WTO). In accordance with it, Serbia gives up a self-sufficiency strategy for any product, which implies market liberalization and free trade with other countries. Regarding that Serbia is aiming to become a member of the EU and the WTO, agriculture should prepare for competition on developed market, free from trade barriers. Current bilateral agreements in free trade with neighbouring countries, Serbia has replaced in 2006 with one within the CEFTA (Central European Free Trade Agreement) agreement, by which has entered the market of around 27 million inhabitants and has accepted a responsibility to realize it, aiming to promote trade in this region. The stabilization and Association Agreement (SAA) provides, in quantity sense, a new level to preferential relations between Serbian agriculture exchange and the EU agriculture, while it provides an asymmetry in Serbia's favour, after which the European Union determines and continuous its duty free import of agro-food products from Serbia, and Serbia gradually decreases its customs duties and other taxes, during the fiveyear- lasting transitional period, for the most of these products.
Pipe Roughness Identification of Water Distribution Networks: The Full Turbulent Case

description: This paper proposes a technique to identify individual pipe roughness parameters in a water distribution network by means of the inversion of the steady-state hydraulic network equations. By enabling the reconstruction of these hydraulic friction parameters to be reliable, this technique improves the conventional model's accuracy and thereby promises to enhance model-based leakage detection and localization. As it is the case in so-called fireflow tests, this methodology is founded on the premise to measure the pressure distributed at a subset of nodes in the network's graph while assuming the nodal consumption to be known. Beside of the proposed problem formulation, which is restricted to only allow turbulent flow in each of the network's pipes initially, developed algorithms are presented and evaluated using simulation examples.

description: Agricultural production in Serbia is one the most important segments of the national economy. Serbia is exporting more agricultural product than importing. Food processors who are responding to the wholesale and retail demand are looking for commodities with specific attributes. Industrialised agriculture grows and makes the rules on the market. In contrast, it has been recognised for some time that small agricultural producers in Serbia have been under huge economic pressure. As a result of impressive changes in market demand and in agricultural policy small agricultural produces in Serbia need to adjust their production structure. Market developments provide niche opportunities for small producers that are able to differentiate production and respond promptly. To capture these opportunity small farmers could use appropriate supply chains and supply chain strategies as well as decision making strategies for the development of partnership, especially planning for successful marketing. The aim of this paper is to analyse the supply chain models for the small Serbian farmers. The results show that small producers in Serbia face increased competition by big player in the market. The wholesale and retail permanently increase criteria for suppliers. Small producers have possibility to use niche opportunities in approaching consumers.

description: Macedonian vegetable farms face big challenge in decision making to improve their production plans. To increase economic efficiency, different tools could be applied that beside natural conditions, resource allocation, technical and technological conditions, consider also economic viewpoint. In this paper we present an example of a spreadsheet tool based on mathematical programming paradigm. It enables one to utilise optimization potential of linear programming, with an objective function of maximising the expected gross margin, subject to set of different constraints. To have a representative tool, special focus has been put on data that are obtained with direct interviews with relevant experts and stakeholders: researchers, crop technology specialists, extension agents, input suppliers and vegetable farmers and supplemented with Farm Monitoring System data for 2010. The tool was tested on hypothetical vegetable farm. It proved to be an efficient tool that could support operative, tactical and strategic planning at the farm level, since it facilitates the selection of adequate production activities of vegetable crops, while taking into consideration the limitations of the available production factors. Due to its flexibility it is also an appropriate tool for analysing decision making in different production conditions that may occur.

description: An electron moving on plane in a uniform magnetic field orthogonal to plane is known as the Landau problem. Wigner functions for the Landau problem when the plane is noncommutative are found employing solutions of the Schroedinger equation as well as solving the ordinary *-genvalue equation in terms of an effective Hamiltonian. Then, we let momenta and coordinates of the phase space be noncommutative and introduce a generalized *-genvalue equation. We solve this equation to find the related Wigner functions and show that under an appropriate choice of noncommutativity relations they are independent of noncommutativity parameter.

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: We have measured the enhancement of the static incommensurate spin-density wave (SDW) order by an applied magnetic field in stage-4 and stage-6 samples of superconducting La2CuO(4+y). We show that the stage-6 La2CuO(4+y) (Tc=32 K) forms static long-range SDW order with the same wave-vector as that in the previously studied stage-4 material. We have measured the field dependence of the SDW magnetic Bragg peaks in both stage-4 and stage-6 materials at fields up to 14.5 T. A recent model of competing SDW order and superconductivity describes these data well.

description: Agile methods, especially Scrum, have become staples of the modern software development industry. Retrospective meetings are Scrum's instrument for process improvement and adaptation. They are considered one of the most important aspects of the Scrum method and its implementation in organizations. However, Retrospectives face their own challenges. Agile practitioners have highlighted common problems, i.e. headaches, that repeatedly appear in meetings and negatively impact the quality of process improvement efforts. To remedy these headaches, Retrospective activities, which can help teams think together and break the usual routine, have been proposed. In this research, we present case studies of educational and industry teams, investigating the effects of eleven Retrospective activities on five identified headaches. While we find evidence for the claimed benefits of activities in the majority of studied cases, application of remedies also led to new headaches arising.

description: Alan Cuthbert carried out ground-breaking work on epithelial ion transport. He used radiolabelled amiloride and benzamil to measure the sodium channel density in epithelia from frog skin and toad bladder, tissues that are good models for the distal section of the mammalian kidney tubule. This work shed important new light on how the properties of these channels were modified by hormones such as aldosterone and antidiuretic hormone, and increased our understanding of how diuretics affect kidney function. Later, he focused on the ion transport deficits that underlie cystic fibrosis (CF), and was a member of the team that showed that the ion transport defect could be corrected in CF transgenic mice by gene therapy. Alan was Sheild Professor of Pharmacology and Head of the Department of Pharmacology at the University of Cambridge from 1979 until his retirement in 1999. During this time he was instrumental in moving the Department from the Addenbrooke's Hospital site to a new building in the centre of town. He was also Master of Fitzwilliam College from 1991 until 1999. Alan made major contributions to pharmacology nationally and internationally, serving as chairman of the editorial board of the British Journal of Pharmacology for eight years, and as President of the Federation of European Pharmacological Societies for two years. In recognition of his contributions to the subject, the British Pharmacological Society awarded him their Wellcome Gold Medal in 2005. After his retirement, he continued his research in the Department of Medicine, pursuing novel pharmacological approaches to the treatment of CF.

description: This paper deals with reconsidering the reliability of the results obtained in the input-output analysis of water consumption by Hristov et al. (2012) due to uncertainty integrated in the data. The imprecision and uncertainty is studied within a workable fuzzy environment introduced by Beynon et al. (2005) where rank reversal is plausible. In addition, the water intensive structure of the Macedonian economy is investigated by applying Dietzenbacher eigenvector methodology (1992) in terms of water consumption. Similar as in the analysis in the work by Hristov et al. (2012), the water intensive structure in Macedonia mainly focused around agriculture and several industrial sectors is confirmed, given the fact that rank reversal was absent. Consequently, necessity to introduce changes in the agricultural production technology and specialization in the production in this region or maybe reconsidering the existing water pricing policy ought to be carefully considered by the policy makers.

description: The aim of this paper is to analyse the technical efficiency of pig production farms in the Republic of Macedonia. The Macedonian pig production sub-sector become increasingly inefficient during the period of economic transition; the country is net-importer of pig meat from countries that produce at lower production costs. Farmers are faced with the challenge to increase their efficiency of production thus to become more competitive; this is affected by the decisions made with regard to the quantities of utilised inputs and produced outputs. In this study technical efficiency is explained from output oriented perspective, assessing the possibility of farmers to increase the efficiency by producing maximum output quantities. The technical efficiency is estimated by employing the parametric Stochastic Frontier Analysis. An empirical analysis was carried out on the data collected by questionnaires in 2010. The results show altered technical efficiency levels in each decision making unit.

description: In this paper we have devised an alternative methodological approach for quantifying utility in terms of expected information content of the decision-maker's choice set. We have proposed an extension to the concept of utility by incorporating extrinsic utility; which we have defined as the utility derived from the element of choice afforded to the decision-maker by the availability of an object within his or her object set. We have subsequently applied this extended utility concept to the case of investor utility derived from a structured, financial product - an custom-made investment portfolio incorporating an endogenous capital-guarantee through inclusion of cash as a risk-free asset, based on the Black-Scholes derivative-pricing formulation.
