description: Nella presente nota è descritta Typhloreicheia flaviae n. sp., scoperta nella Grotta di Istirzili N° 50 Sa/NU, 507 m s.l.m. (Sardegna centro-orientale, Supramonte di Baunei, Ogliastra). La nuova specie è affine a T. casalei Magrini, Marcia & Onnis, 2011, nota di una grotta del Supramonte di Urzulei, ma se ne differenzia per numerosi caratteri indicati nel testo e illustrati nelle figure; in particolare: dimensioni nettamente minori, corpo più depresso, tegumenti meno lucidi, pronoto più ristretto alla base, lobo mediano dell’edeago con apice più appuntito in visione laterale e meno inclinato ventralmente, in visione ventrale più dritto e simmetrico, lamella copulatrice con apice conformato diversamente. La nuova specie non presenta caratteri adattativi alla vita ipogea particolarmente evidenti, ma è complessivamente simile ad altri taxa, endogei o tipici dell’MSS, reperiti recentemente in cavità della Sardegna orientale e meridionale: T. carlonnisi Magrini, Marcia & Casale, 2011, T. casalei Magrini, Marcia & Onnis, 2011 e T. grafittii Magrini, Onnis, Casale & Marcia, 2012. Sono inoltre riportate alcune note addizionali sulla distribuzione di Typhloreicheia bulirschi Magrini & Bastianini, 2011 nella Sardegna meridionale.

Freedom in the Expansion and Obstacles to Integrability in Multiple-Soliton Solutions of the Perturbed KdV Equation

Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: The construction of a solution of the perturbed KdV equation encounters obstacles to asymptotic integrability beyond the first order, when the zero-order approximation is a multiple-soliton wave. In the standard analysis, the obstacles lead to the loss of integrability of the Normal Form, resulting in a zero-order term, which does not have the simple structure of the solution of the unperturbed equation. Exploiting the freedom in the perturbative expansion, we propose an algorithm that shifts the effect of the obstacles from the Normal Form to the higher-order terms. The Normal Form then remains integrable, and the zero-order approximation retains the multiple-soliton structure of the unperturbed solution. The obstacles are expressed in terms of symmetries of the unperturbed equation, and decay exponentially away from the soliton-interaction region. As a result, they generate a bounded correction term, which decays exponentially away from the origin in the x-t plane. The computation is performed through second order.

description: There is no single 'best way' of policy development. Bottom-up approaches to policy design and a broad debate among stakeholders facilitate policy learning and innovation. A novel approach of a bottom-up policy design process involving stakeholders is introduced. First results obtained by this methodology are presented. The outcomes of a large international effort for a development of policies for organic food and farming in Mai 2004 in Europe are analyzed: the synthesized results from 11 European countries (AT, CH, CZ, DE, DK, EE, GB, HU, IT, PL, SI) on the current situation of policies related to the organic food market in Europe are highlighted and policy recommendations for the development of the organic food and farming sector formulated. Specifically, strengths, weaknesses, opportunities and threats of policies related to organic food market are identified and policy instruments to address these aspects are developed.

description: It has recently been shown that a simple empirical formula, in terms of the mass number and the valence nucleon numbers, is able to describe the main trends of the lowest excitation energies of the natural parity even multipole states up to $10^+$ in even-even nuclei throughout the entire periodic table. In an effort to understand why such a simple formula is so capable, we investigate the possibility of associating each term of the empirical formula with the specific part of the measured excitation energy graph.

description: The aim of this paper is to estimate the competitive level of fresh fish exports among the Euro Mediterranean countries. Revealed Comparative Advantage indices of Italian, French, Greek, Portuguese and Spanish fresh fish are estimated, in order to gain new insights regarding the position of these products in the market of the European Union, in terms of competitiveness. In addition, this study investigates the parameters affecting the competitive level among countries, using Cointegration and Innovation Accounting methodology. The estimated Comparative Advantage indices reveal that there is a wide range of competitiveness among Euro Mediterranean countries. In addition, the investigation of the dynamic characteristics of competitiveness reveals that the competitive position for each country is affecting at different level by different factors, constituting a dynamic market that can be easily affected by changes in the volatile marketing environment.

description: We present the results of a detailed temporal analysis of the bright BL Lac object Mrk 421 using the three available long timing mode observations by the EPIC PN camera. This detector mode is characterized by its long life time and is largely free of photon pile-up problems. The source was found in different intensity and variability states differing by up to more than a factor of three in count rate. A time resolved cross correlation analysis between the soft and hard energy bands revealed that the characteristics of the correlated emission, with lags of both signs, change on time scales of a few thousand seconds. Individual spectra, resolved on time scales of a few hundread seconds, can be quite well fitted by a broken power law. We find significant spectral variations on time scales as short as 500-1000 sec. Both the hard and the soft band spectral indices show a non-linear correlation with the source flux. A comparison of the observed light curves with numerical results from relativistic hydrodynamic computer simulations of the currently favored shock-in-jet models indicates that any determination of the jet's physical parameters from `simple' emission models must be regarded with caution: at any time we are seeing the emission from several emission regions distinct in space and time, which are connected by the complex hydrodynamic evolution of the non-uniform jet.

description: Political and economic changes over the last ten years have intensified agri-food trade among Mediterranean countries. This paper aims to examine the exchanges between Italy and these countries. The analysis of these exchanges highlight trends that indicate Italy's agri-food balance has deteriorated during the previous ten years. A Constant Market Shares Analysis has been performed on Italy's fruit and vegetable imports from Egypt, Turkey, Morocco and Tunisia, which aims to assess their competitiveness. The results are then compared with those of Italy's major fruit and vegetable suppliers, the EU and Latin America, which indicate some Mediterranean Partners have high levels of competitiveness.

description: The in-plane phonon-drag thermopower $S^g$, diffusion thermopower $S^d$ and the power factor $PF$ are theoretically investigated in twisted bilayer graphene (tBLG) as a function of twist angle $θ$, temperature $T$ and electron density $n_s$ in the region of low $T$ (1-20 K). As $θ$ approaches magic angle $θ_m$, the $S^g$ and $S^d$ are found to be strongly enhanced, which is manifestation of great suppression of Fermi velocity ${ν_F}^*$ of electrons in moire flat band near $θ_m$. This enhancement decreases with increasing $θ$ and $T$. In the Bloch- Gruneisen (BG) regime, it is found that $S^g \sim {ν_F}^{* -2}$, $T^3$ and ${n_s}^{-1/2}$. As $T$ increases, the exponent $δ$ in $S^g \sim T^δ$, changes from 3 to nearly zero and a maximum $S^g$ value of $\sim$ 10 mV/K at $\sim$ 20 K is estimated. $S^g$ is larger (smaller) for smaller $n_s$ in low (high) temperature region. On the other hand, $S^d$, taken to be governed by Mott formula, $\sim {ν_F}^{* -1}$, $T$ and ${n_s}^{-1/2}$ and $S^d< \sim$ 2 K. The power factor $PF$ is also found to be strongly $θ$ dependent and very much enhanced. Consequently, possibility of a giant figure of merit is discussed.In tBLG, $θ$ acts as a strong tuning parameter of both $S^g$ and $S^d$ and $PF$ in addition to $T$ and $n_s$. Our results are qualitatively compared with the measured out-of-plane thermopower in tBLG.

Peeling tomato paste subsidies

description: The Common Market Organisation (CMO) for fruit and vegetable products is currently evaluated by the European Commission. The evaluation may lead to a reform of the CMO. One of the elements under debate is the production subsidy for processing tomatoes. The processing tomato sector is one of most heavily subsidized sectors in primary production of fruit and vegetables. The current production subsidy equals approximately 50% of producer turnover. This paper evaluates two possible reforms of the processing tomato supply chain: (1) an abolishment of the production subsidy and (2) a replacement of the production subsidy by area payments (decoupling). The evaluation focuses on the impact the reform may have on production and trade patterns of fruits and vegetables in Europe. On the basis of a simulation model, the paper argues that in the first scenario production will shift in the Mediterranean from processing tomatoes and extensive crop production in general towards fruit and fruit vegetables. The abolishment of the production subsidy will lead to a production shift in the direction in which Mediterranean countries have a comparative advantage. In the second scenario, Mediterranean production will remain stuck in extensive crop production: processing tomatoes, extensive vegetables and arable crops. In the first scenario, Mediterranean countries will crowd out North European fruit production. As a result, North European production shifts towards vegetable production. In the second scenario, the impact on North Europe is negligible.

The Weak Shock in the Core of the Perseus Cluster

description: The dissipation of energy from sound waves and weak shocks is one of the most promising mechanisms for coupling AGN activity to the surrounding intracluster medium (ICM), and so offsetting cooling in cluster cores. We present a detailed analysis of the weak shock found in deep Chandra observations of the Perseus cluster core. A comparison of the spectra either side of the shock front shows that they are very similar. By performing a deprojection analysis of a sector containing the shock, we produce temperature and density profiles across the shock front. These show no evidence for a temperature jump coincident with the density jump. To understand this result, we model the shock formation using 1D hydrodynamic simulations including models with thermal conduction and gamma < 5/3 gas. These models do not agree well with the data, suggesting that further physics is needed to explain the shock structure. We suggest that an interaction between the shock and the H-alpha filaments could have a significant effect on cooling the post-shock gas. We also calculate the thermal energy liberated by the weak shock. The total energy in the shocked region is about 3.5 times the work needed to inflate the bubbles adiabatically, and the power of the shock is around 6x10^44 erg/s per bubble, just over 10^45 erg/s in total.

description: The linear instability that induces a relativistic electron beam passing through a return plasma current to filament transversely is often related to some filamentation mode with wave vector normal to the beam or confused with Weibel modes. We show that these modes may not be relevant in this matter and identify the most unstable mode on the two-stream/filamentation branch as the main trigger for filamentation. This sets both the characteristic transverse and longitudinal filamentation scales in the non-resistive initial stage.

description: We address the problem of determining the type I, type II or borderline dual superconductor behavior in maximal Abelian gauge SU(2) through the study of the dual Abrikosov vortex. We find that significant electric currents in the simulation data call into question the use of the dual Ginzburg Landau Higgs model in interpreting the data. Further, two definitions of the penetration depth parameter take two different values. The splitting of this parameter into two is intricately connected to the existence of electric currents. It is important in our approach that we employ definitions of flux and electric and magnetic currents that respect Maxwell equations exactly for lattice averages independent of lattice spacings. Applied to specific Wilson loop sizes, our conclusions differ from those that use the dual GLH model.

Strengthened PT-symmetry with P $\neq$ P$^\dagger$
Creators: name: Znojil, Miloslav
Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Two alternative scenarios are shown possible in Quantum Mechanics working with non-Hermitian $PT-$symmetric form of observables. While, usually, people assume that $P$ is a self-adjoint indefinite metric in Hilbert space (and that their $P-$pseudo-Hermitian Hamiltonians $H$ possess the real spectra etc), we propose to relax the constraint $P=P^\dagger$ as redundant. Non-Hermitian triplet of coupled square wells is chosen for illustration purposes. Its solutions are constructed and the observed degeneracy of their spectrum is attributed to the characteristic nontrivial symmetry $S={P}^{-1} {P}^\dagger \neq I$ of the model $H$. Due to the solvability of the model the determination of the domain where the energies remain real is straightforward. A few remarks on the correct (albeit ambiguous) physical interpretation of the model are added.

description: This paper has analysed the import demand for virgin olive oil in the EU and more precisely in the Italian market, as it concentrates more than 80% of EU imports, aiming to determine the relative position of Mediterranean EU and non-EU countries exports and their degree of substitutability or complementarity. The methodology used is based on the specification of a Threshold Almost Ideal Demand System in which special attention has been paid to the stochastic properties of the series involved. In an empirical context, the paper has aimed to provide a set of import demand elasticities that can be useful in trade models. Results point to Spain as the leader in the Italian virgin olive oil market. It is expected that this position will be maintained in the future. Greece has improved its relative position after its accession into the EU. However, imports coming from Greece are highly dependent on the situation in Spain. Tunisia has good potential for future exports development as a consequence of new perspectives of trade liberalisation taking into account its relative position in the Italian market, in spite that its exports are currently constrained due to existing quotas.

Spatial association learning by rufous hummingbirds (Selasphorus rufus)
Creators: name: Wilhelmson, Christianne Elly
Publisher: name: University of British Columbia
Year: 2009

description: Foraging theory provides a framework for understanding why animals make certain foraging decisions yet provides few insights into how these decisions are made. Psychological studies provide understanding of cognitive mechanisms but without the needed ecological context. This thesis continues the study of spatial association memory in rufous hummingbirds (Selasphorus rufus) in an attempt to understand its possible utility in the wild. In laboratory settings, rufous hummingbirds make associations between two spatially separate objects (a cue and a reward/response site) using spatial association memory. In Chapter Two, I investigated the ability of rufous hummingbirds to switch from using spatial memory to spatial association memory when visible cues remained reliable indicators of food location, even when the food location was changed repeatedly. Regardless of how often birds obtained food from the same location, they quickly used spatial association memory to relocate the reward when it was moved. Birds initially used spatial memory to locate the reward but once this failed they used the available light cue to learn the spatial association. Once birds were using spatial association memory, the spatial memory of the rewarding location was not reinforced in memory as they relied only on the association to locate the reward. In Chapter Three, I found evidence that the components of spatial association memory (the cue and the reward/response site) can be utilized separately from the association itself. Once birds learned a spatial association, a spatial memory of the currently and previously rewarding location remained in the absence of the light cue and this spatial memory was strengthened when birds fed repeatedly from the same location. This supports Brown (1992) who suggested that hummingbirds make spatial associations according to Gestalt theory, in which both the association and its parts are presumed to be perceived and remembered. I uncovered this information through analysis of intertrial activity, previously presumed to be independent of within trial behavior. Spatial association memory is more complex and flexible than expected and has characteristics to be useful in the wild, possibly to adjust quickly to profitability changes in flowers and patches.

description: Multi-hop Question Generation (QG) aims to generate answer-related questions by aggregating and reasoning over multiple scattered evidence from different paragraphs. It is a more challenging yet under-explored task compared to conventional single-hop QG, where the questions are generated from the sentence containing the answer or nearby sentences in the same paragraph without complex reasoning. To address the additional challenges in multi-hop QG, we propose Multi-Hop Encoding Fusion Network for Question Generation (MulQG), which does context encoding in multiple hops with Graph Convolutional Network and encoding fusion via an Encoder Reasoning Gate. To the best of our knowledge, we are the first to tackle the challenge of multi-hop reasoning over paragraphs without any sentence-level information. Empirical results on HotpotQA dataset demonstrate the effectiveness of our method, in comparison with baselines on automatic evaluation metrics. Moreover, from the human evaluation, our proposed model is able to generate fluent questions with high completeness and outperforms the strongest baseline by 20.8% in the multi-hop evaluation.

description: This paper investigates farm level technical inefficiency of production and its determinants in a sample of 150 citrus producing farms in Tunisia using a stochastic frontier production function approach applied to cross section data. Results indicate that technical efficiency of production in the sample of citrus producing farms investigated ranges from a minimum of 26.84% to a maximum of 97.98% with an average technical efficiency estimate of 86.23%. This suggests that citrus producers may increase their production by as much as 13.77% through more efficient use of production inputs. Further, the estimated coefficients in the technical inefficiency model indicate the positive effect on technical efficiency of the share of productive trees, the agricultural training, irrigation operations and the experience of farmer.

The following new synonymies are established: Pseudeuparius centromaculatus (Gyllenhal, 1833) [= P. pictus (Betta, 1857) syn. n.]; Pachytychius sparsutus (Olivier, 1807) [= P. aericollis (Betta, 1857) syn. n.]; Smicronyx coecus (Reich, 1797) [= S. minusculus (Betta, 1857) syn. n.]; Mecinus labilis (Herbst, 1795) [= M. vittatus (Betta, 1857) syn. n.]; Mecinus pascuorum (Gyllenhal, 1813) [= M. areolatus (Betta, 1857) syn. n.]; Mecinus latiusculus (Jacquelin du Val, 1855) [= M. flavipes (Betta, 1857) syn. n.]; Mecinus circulatus (Marsham, 1802) [= M. sericatus Betta, 1857 syn. n.].

description: The spatially-resolved relaxation characteristics of photoinduced quasiparticles (QPs) in CuO$sub 2$ planes of underdoped YBCO are disclosed by polarized fs time-resolved spectroscopy. The relaxation time (tau) along b axis diverges at Tc, and appears to be governed by a temperature-dependent gap Delta(T) at T < Tc. Furthermore, for T > Tc, a monotonic increase of tau with decreasing T along the b axis and ab diagonal was observed and can be attributed to a temperature-independent gap Delta$sub p$. The results lend support to recombination dominant scenario of QP dynamics. However, the QP thermalization may take part along the nodal direction in the highly underdoped samples.

Non-LTE Spectra of Accretion Disks Around Intermediate-Mass Black Holes

Publisher: name: arXiv
Year: 2005

description: We have calculated the structures and the emergent spectra of stationary, geometrically thin accretion disks around 100 and 1000 M_sun black holes in both the Schwarzschild and extreme Kerr metrics. Equations of radiative transfer, hydrostatic equilibrium, energy balance, ionization equilibrium, and statistical equilibrium are solved simultaneously and consistently. The six most astrophysically abundant elements (H, He, C, N, O, and Fe) are included, as well as energy transfer by Comptonization. The observed spectrum as a function of viewing angle is computed incorporating all general relativistic effects. We find that, in contrast with the predictions of the commonly-used multi-color disk (MCD) model, opacity associated with photoionization of heavy elements can significantly alter the spectrum near its peak. These ionization edges can create spectral breaks visible in the spectra of slowly-spinning black holes viewed from almost all angles and in the spectra of rapidly-spinning black holes seen approximately pole-on. For fixed mass and accretion rate relative to Eddington, both the black hole spin and the viewing angle can significantly shift the observed peak energy of the spectrum, particularly for rapid spin viewed obliquely or edge-on. We present a detailed test of the approximations made in various forms of the MCD model. Linear limb-darkening is confirmed to be a reasonable approximation for the integrated flux, but not for many specific frequencies of interest.

description: Non-Hermitian topological systems are the newest additions to the growing field of topological matter. In this work, we report of the light-driven exceptional physics in a multi-Weyl semi-metal. The driving is not only a key ingredient to control the position of the exceptional contours (ECs), light also has the ability to generate new ECs. Interestingly, we also demonstrate topological charge distribution and Lifshitz transition, which are controllable by the driving field in such generated ECs. Our findings present a promising platform for the manipulation and control over exceptional physics in non-Hermitian topological matter.

description: We study the phase diagram and the pion modes in the electrically neutral two flavor PNJL model. One of the main result of this paper is that when electrical neutrality is required, pions do not condense in the ground state of the model: the isospin chemical potential $μ_I = -μ_e/2$ is always smaller than the value required for pion condensation to occur. Moreover we investigate on the pions and $σ$ mass spectra. We find that the qualitative behavior of the masses resembles that obtained in the NJL model. We close this paper by studying the intriguing possibility that a bound state with the quantum numbers of the pions can be formed above the chiral phase transition.

description: We observed two faint tidal dwarf galaxies (TDGs), NGC 5291N and NGC 5291 S with the Infrared Spectrograph on the Spitzer Space Telescope. We detect strong polycyclic aromatic hydrocarbon (PAH) emission, which match models of groups of \~100 carbon atoms with an equal mixture of neutral and ionized PAHs. The TDGs have a dominant warm ~140 K dust component in marked contrast to the cooler, 40-60 K dust found in starburst galaxies. For the first time we detect the low-J rotational lines from molecular hydrogen. Adopting LTE there is ~10^5 solar masses of ~400 K gas, which is <0.1 % of the cold gas mass. The combination of one-third solar metallicity with a recent, <5 million year, epsiode of star formation is reflected in the S and Ne ratios. The excitation is higher than typical values for starburst galaxies and similar to that found in BCDs. Using the Infared Array Camera we identify an additional 13 PAH-rich candidate TDGs. These sources occupy a distinct region of IRAC color space with [3.6] - [4.5] < 0.4 and [4.5] - [8.0] > 3.2. NGC 5291 N and S have stellar masses of (1.5 and 3.0) 10^8 solar masses, which is comparable to BCDs. This system appears to be a remarkable TDG nursery.

description: We compute the cosmological reduction of the fourth powers of the Riemann tensor claimed to arise in string theory at order $α'^{\,3}$, with overall coefficient proportional to $ζ(3)$, and show that it is compatible with an $O(9,9)$ symmetry. This confirms the general result in string theory, due to Sen, that classical string theory with $d$-dimensional translation invariance admits an $O(d,d)$ symmetry to all orders in $α'$.
description: 10 pages, v2: Major changes. Puzzle alluded to in the original title has been resolved by finding a computational mistake.

Discounting and Sustainability

Publisher: name: Unknown
Year: 1992
Subjects: Environmental Economics and Policy

description: The discounting of future benefits has long been one of the most controversial, and in many ways, unsatisfactory, aspects of benefit -cost analysis. This concern has been heightened by the rise of the environmental movement and, particularly by the debate over sustainable development. The sustainability approach is presented as an alternative to the standard benefit-cost analysis approach to the question of inter-generational equity. Sustainability is in fashion, and, as with all fashionable terms, it has been used in many ways and in support of many different policy agendas. A summary and critique of the literature is given by Ule (1991). I shall interpret sustainability very broadly to encompass two main concerns: (i) The interests of future generations should be given equal weight with our own in making decisions affecting the long term future; (ii) It should not be assumed that capital (that is, technology embodied in produced goods) can be substituted indefinitely to compensate for land (taken broadly to include all the contributions of the natural environment to human welfare, and agricultural production in particular). In this paper, the relationship between the idea of sustainability and the older literature on optimal growth is examined and implications for discounting, income distribution and the treatment of uncertainty are explored.
Freeze-Thaw Characteristics of Aggregates
Creators: name: Laughlin, George R.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1965
Subjects: subject: Transportation Engineering

description: Premature deterioration of concrete under freezing and thawing conditions is often attributable to the aggregate fraction. Past research has shown that the freeze-thaw characteristics of aggregate are related, in a general way, to such properties as: 1) porosity, 2) absorption, and 3) bulk specific gravity. Actually it is the pore system--that is, the size, shape, arrangement and continuity of the pores--that governs the freeze-thaw characteristics. Distress in aggregate particles arises from hydrostatic pressure induced when a portion of its absorbed pore-water is frozen. The degree of distress or damage manifested is dependent upon the amount of permeable porosity, the degree of saturation, the severity of freezing, and the rupture strength of the rock particle and the restraint imposed upon it.
