Taxonomy and re-description of Philaenus Mediterranean species

Publisher: name: Zenodo
Year: 2019

description: Philaenus spumarius (Hemiptera: Aphrophoridae) is the efficient vector of Xylella fastidiosa in Italy and is found mixed with P. tesselatus and P. maghresignus in Tunisia. This approach starts studying Philaenus collected by sweep-net in Italy (Puglia) and in Tunisia to differentiate the three species. Tunisian materials originate from Ben Arous, Nabeul, Bizerte, Béja, Jendouba, Kairouan in Pinus and Quercus forest also on Pistacia or Asphodelus understory, in Olive, Peach, Citrus and Grapevines orchards, and on natural herbs or weeds. Apart from the interest in describing Tunisian fauna of Hemiptera, we need a clear Taxonomic contribution based on the study of male genitalia for the identification of the eight Philaenus species. The need arises because one of the species (P. spumarius) is a highly efficient vector of X. fastidiosa: a quarantine plant pathogenic bacterium threatening plant health in the Mediterranean basin. The correct specific identification will allow quantitative sampling and consequent effective control measures and strategy building. The only comparative paper considers eight species and is useful for the skilled researchers but less accessible for phytosanitary services or other students starting comparative identification.

description: We develop a dynamic framework to detect the occurrence of permanent and transitory breaks in the illiquidity process. We propose various tests that can be applied separately to individual events and can be aggregated across different events over time for a given firm or across different firms. In an empirical study, we use this methodology to study the impact of stock splits on the illiquidity dynamics of the Dow Jones index constituents and the effects of reverse splits using stocks from the S&P 500, S&P 400 and S&P 600 indices. Our empirical results show that stock splits have a positive and significant effect on the permanent component of the illiquidity process while a majority of the stocks engaging in reverse splits experience an improvement in liquidity conditions.

description: Double and triple detachment of the F-(1s2 2s2 2p6) negative ion by a single photon have been investigated in the photon energy range 660 to 1000 eV. The experimental data provide unambiguous evidence for the dominant role of direct photo-double-detachment with a subsequent single-Auger process in the reaction channel leading to F2+ product ions. Absolute cross sections were determined for the direct removal of a (1s+2p) pair of electrons from F- by the absorption of a single photon.
Estimating a Density Ratio Model for Stock Market Risk and Option Demand

description: Option-implied risk-neutral densities are widely used for constructing forward-looking risk measures. Meanwhile, investor risk aversion introduces a multiplicative pricing kernel between the risk-neutral and true conditional densities of the underlying asset’s return. This paper proposes a simple local estimator of the pricing kernel based on inverse density weighting, and characterizes its asymptotic bias and variance. The estimator can be used to correct biased density forecasts, and performs well in a simulation study. A local exponential linear variant of the estimator is proposed to include conditioning variables. In an application, we estimate a demand-based model for S&P 500 index options using net positions data, and attribute the U-shaped pricing kernel to heterogeneous beliefs about conditional volatility.

Anmerkung: Die beiden krainerischen Höhlen-Lithobiiden sind von besonderem Interesse insofern, als man an ihnen mit aller Deutlichkeit die Abstammung von oberirdischen Formen nachweisen kann. Während nämlich der Lithobius stygius Latz, von dem illyricus Latz abzuleiten ist, stellt der Polybothrus cerberus m. einen cavernicolen Abkömmling des leptopus Latz vor.
In beiden Artenpaaren ist durch den Uebergang zum Höhlenleben die Zahl der Ocellen vermindert. Während aber bei der beiden Lithobius-Arten in der Pigmentierung nicht viel Unterschied zu bemerken ist, zeigt sich dieselbe bei Polybothrus cerberus ebenfalls bedeutend vermindert. Die Zahl der Antennenglieder ist dagegen nicht oder doch nur geringfügig bei cerberus vermehrt.

description: We show that in certain limits the (1+1)-dimensional massive Thirring model at finite temperature $T$ is equivalent to a one-dimensional Coulomb gas of charged particles at the same $T$. This equivalence is then used to explore the phase structure of the massive Thirring model. For strong coupling and $T>>m$ (the fermion mass) the system is shown to behave as a free gas of "molecules" (charge pairs in the Coulomb gas terminology) made of pairs of chiral condensates. This binding of chiral condensates is responsible for the restoration of chiral symmetry as $T\to\infty$. In addition, when a fermion chemical potential $μ\neq 0$ is included, the analogy with a Coulomb gas still holds with $μ$ playing the role of a purely imaginary external electric field. For small $T$ and $μ$ we find a typical massive Fermi gas behaviour for the fermion density, whereas for large $μ$ it shows chiral restoration by means of a vanishing effective fermion mass. Some similarities with the chiral properties of low-energy QCD at finite $T$ and baryon chemical potential are discussed.

description: Why are certain movies more successful in some markets than others? Are the entertainment products we consume reflective of our core values and beliefs? These questions drive our investigation into the relationship between a society’s oral tradition and the financial success of films. We combine a unique catalog of local tales, myths, and legends around the world with data on international movie screenings and revenues. First, we quantify the similarity between movies’ plots and traditional motifs employing machine learning techniques. Comparing the same movie across different markets, we establish that films that resonate more with local folklore systematically accrue higher revenue and are more likely to be screened. Second, we document analogous patterns within the US. Google Trends data reveal a pronounced interest in markets where ancestral narratives align more closely with a movie’s theme. Third, we delve into the explicit values transmitted by films, concentrating on the depiction of risk and gender roles. Films that promote risk-taking sell more in entrepreneurial societies today, rooted in traditions where characters pursue dangerous tasks successfully. Films portraying women in stereotypical roles continue to find a robust audience in societies with similar gender stereotypes in their folklore and where women today continue being relegated to subordinate positions. These findings underscore the enduring influence of traditional storytelling on entertainment patterns in the 21st century, highlighting a profound connection between movie consumption and deeply ingrained cultural narratives and values.

Analytical Soft SUSY Spectrum in Mirage-Type Mediation Scenarios

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

description: We derive explicitly the soft SUSY breaking parameters at arbitrary low energy scale in the (deflected) mirage type mediation scenarios with possible gauge or Yukawa mediation contributions. Based on the Wilsonian effective action after integrating out the messengers, we obtain analytically the boundary value (at the GUT scale) dependencies of the effective wavefunctions and gauge kinetic terms. Note that the messenger scale dependencies of the effective wavefunctions and gauge kinetic terms had already been discussed in GMSB. The RGE boundary value dependencies, which is a special feature in (deflected) mirage type mediation, is the key new ingredients in this study. The appearance of $'mirage'$ unification scale in mirage mediation is proved rigorously with our analytical results. We also discuss briefly the new features in deflected mirage mediation scenario in the case the deflection comes purely from the Kahler potential and the case with messenger-matter interactions.

description: Using administrative transactions data from the United Kingdom, we document a swift decline in sterling use among British exporters after the 2016 Brexit vote. Through a novel decomposition, we document most of this decline comes from two sources: (i) continuously-operating firms switching from sterling to dollars or local currencies and (ii) reductions in transactions for sterling-loyal firms. In contrast, new entrants into exporting primarily invoice in sterling before and after the Brexit vote. Our findings provide the first evidence on the quantitative relevance of new channels that contribute to changes in aggregate invoicing shares amidst political upheaval.

description: We study the effects of electron-electron interaction on the critical properties of the plateau transitions in the {\it integer} quantum Hall effect. We find the renormalization group dimension associated with short-range interactions to be $-0.66\pm0.04$. Thus the non-interacting fixed point (characterized $z=2$ and $ν\approx 2.3$) is stable. For the Coulomb interaction, we find the correlation effect is a marginal perturbation at a Hartree-Fock fixed point ($z=1$, $ν\approx 2.3$) by dimension counting. Further calculations are needed to determine its stability upon loop corrections.

description: Single, double, and triple ionization of the C+ ion by a single photon have been investigated in the energy range 286 to 326 eV around the K-shell single-ionization threshold at an unprecedented level of detail. At energy resolutions as low as 12 meV, corresponding to a resolving power of 24000, natural linewidths of the most prominent resonances could be determined. From the measurement of absolute cross sections, oscillator strengths, Einstein coefficients, multi-electron Auger decay rates and other transition parameters of the main K-shell excitation and decay processes are derived. The cross sections are compared to results of previous theoretical calculations. Mixed levels of agreement are found despite the relatively simple atomic structure of the C+ ion with only 5 electrons. This paper is a follow-up of a previous Letter [Müller et al., Phys. Rev. Lett. 114, 013002 (2015)].

description: We introduce loss aversion into a model of conspicuous consumption in networks. Agents allocate heterogeneous incomes between a conventional good and a status good. They interact over a connected network and compare their status consumption to their neighbors’ average consumption. We find that aversion to lying below the social reference point has a profound impact. If loss aversion is large relative to income heterogeneity, a continuum of conformist Nash equilibria emerges. Agents have the same status consumption, despite differences in incomes and network positions, and the equilibrium is indeterminate. Otherwise, there is a unique Nash equilibrium and status consumption depends on the interplay between network positions and incomes. Our analysis extends to homothetic and heterogeneous preferences.

We find the short-range correlations of the ^1S_0 pairing fields to be almost identical to those of the two-nucleon virtual state. We obtain mutually consistent results for the pairing fields, using several different sets of effective interaction parameters, when we demand that each of these sets places the virtual-state pole at its physical location.

description: I analyze a disaggregated structural change model for the US economy in the post-Second World War period. My results reveal that the positive correlation between the relative price and the relative quantity of services with respect to goods, a fact that challenges CES preferences commonly used in the structural change literature, largely reflects the heterogeneous makeup of the services sector. I show that a preference specification where service industries with high productivity growth (progressive services) are separated from the rest of services can account for this positive correlation without any income effects. Consistent with the development facts, the disaggregated structural change model I consider implicates a hump for the relative price of investment. Regarding structural change in investment, the results of the disaggregated model differ from the existing literature. More specifically, the price of services relative to goods declines over time and the rise of the services sector in investment reflects the substitutability between goods and services.

description: We calculate the non-retarded dispersion force exerted on an electrically polarizable quantum particle by a perfectly conducting toroid, which is one of the most common objects exhibiting a non-trivial topology. We employ a convenient method developed by Eberlein and Zietal that essentially relates the quantum problem of calculating dispersion forces between a quantum particle and a perfectly conducting surface of arbitrary shape to a corresponding classical problem of electrostatics. Considering the quantum particle in the symmetry axis of the toroid, we use this method to find an exact analytical result for the van der Waals interaction between the quantum particle and the conducting toroid. Surprisingly, we show that for appropriate values of the two radii of the toroid the dispersive force on the quantum particle is repulsive. This is a remarkable result since repulsion in dispersive interactions involving only electric objects (and particles) in vacuum is rarely reported in the literature. Final comments are made about particular limiting cases as, for instance, the quantum particle-nanoring system.

description: We note that the maximum temperature during reheating can be much greater than the reheating temperature $T_r$ at which the Universe becomes radiation dominated. We show that the Standard Model anomalous $(B+L)$-violating processes can therefore be in thermal equilibrium for 1 GeV $\simlt T_{r}\ll 100$ GeV. Electroweak baryogenesis could work and the traditional upper bound on the Higgs mass coming from the requirement of the preservation of the baryon asymmetry may be relaxed. Alternatively, the baryon asymmetry may be reprocessed by sphaleron transitions either from a $(B-L) $ asymmetry generated by the Affleck-Dine mechanism or from a chiral asymmetry between $e_R$ and $e_L$ in a $B-L = 0$ Universe. Our findings are also relevant to the production of the baryon asymmetry in large extra dimension models.

Energy justice

description: Energy system models are helpful tools for the planning and operation of future energy systems. Energy systems are large, expensive and interconnected; real-world experiments are therefore often impractical and the use of computational techniques is paramount for planning and design. The literature contains many examples of technical models that incorporate techno-economic factors but far fewer cases that model sociocultural aspects. Even when social factors are represented within technical models, they are often considered only to a limited extent. The dominant modelling practice is at odds with the fact that energy systems may deeply affect the communities in which they are embedded.

To understand the state of the practice, we review current energy system modelling approaches that consider equity, equality, and energy justice (EEJ). Relevant, recent articles are identified using the Scopus search engine. We observe an increasing number of modelling studies that consider EEJ concepts with no clear evidence of location-based preference. The studies identified adopt a variety of approaches to quantify EEJ concepts; however, these approaches are largely inconsistent and are most often applied without a clear theoretical basis. Moreover, the methods largely fail to reflect the numerous dimensions of EEJ and tend to concentrate on select aspects of EEJ. Our findings indicate a gap between how modellers conceive EEJ and how EEJ is understood by social scientists and non-academic practitioners. 

To close this gap, technical modellers require further support in determining how they should consider EEJ. This support could include references to study motivation, contextually-appropriate definitions of EEJ, and alternative technical formulations. Providing such guidance would not only help bridge disciplinary gaps but also ensure that models that  consider EEJ do so in a manner that is accepted by the broader community.

description: We present the first calculation of fermion spectral function at finite temperature in quark-meson model in the framework of the functional renormalization group (FRG). We compare the results in two truncations, after first evolving flow equation of effective potential, we investigate the spectral function either by taking the IR values as input to calculate one-loop self-energy or by taking the scale-dependent values as input to evolve the flow equation of the fermion two-point function. The latter one is a self-consistent procedure in the framework of FRG. In both truncations, we find a multi-peak structure in the spectral function, indicating quark collective excitations realized in terms of the Landau damping. However, in contrast to fermion zero-mode in the one-loop truncation, we find a fermion soft-mode in the self-consistent truncation, which approaches the zero-mode as temperature increases.

description: We investigate the effect of supersymmetric CP violating phases on the $B\to X_s γ$ and $B\to X_s l^+l^-$ decays in the minimal supergravity model. We show that the phase of the trilinear scalar coupling constant for top squarks is strongly suppressed and aligned to that of the gaugino mass due to a renormalization effect from the Planck scale to the electroweak scale. As a result, the effect of supersymmetric CP violating phases on the $B \to X_s γ$ and $B \to X_s l^+ l^-$ decays are small taking into account the neutron and the electron electric dipole moment constraints. For the $B \to X_sγ$ decay, the amplitude has almost no new CP violating phase and the direct CP asymmetry is less than 2 %. For the $B \to X_s l^+ l^-$ decay, the branching ratio can be sizably different from that in the standard model only when the sign of the $B \to X_s γ$ amplitude is opposite to that in the standard model.

description: In a joint experimental and theoretical endeavour, photoionization of metastable C4+(1s 2s 3S1) ions via intermediate levels with hollow, double-K-vacancy configurations 2s2p, 2s3p, 2p3s, 2p3d, 2s4p, 2p4s and 2p4d has been investigated. High-resolution photon-ion merged-beams measurements were carried out with the resolving power reaching up to 25,000 which is sufficient to separate the leading fine-structure components of the 2s2p 3P term. Many-body perturbation theory was employed to determine level-to-level cross sections for K-shell excitation with subsequent autoionization. The resonance energies were calculated with inclusion of electron correlation and radiative contributions. Their uncertainties are estimated to be below $\pm$1 meV. Detailed balance confirms the present photoionization cross-section results by comparison with previous dielectronic-recombination measurements. The high accuracy of the theoretical transition energies together with the present experimental results qualify photoabsorption resonances in heliumlike ions as new, greatly improved energy-reference standards at synchrotron radiation facilities.

description: This paper presents experimental evidence on games where individuals can unilaterally decide on their links with each other. Linking decisions give rise to directed graphs. We consider two classes of situations: one, benefits flow along the direction of the network paths (one-way flow), and two, when the benefits flow on network paths without regard to the direction of links (two-way flow). Our experiments reveal that in the one-way flow model subjects create sparse networks whose distance grows and efficiency falls as group size grows; by contrast, in the two-way flow model subjects create sparse and small world networks whose efficiency remains high in both small and large groups. We show that a bounded rational model that combines myopic best response with targeting a most connected individual provides a coherent account of our experimental data.

description: Modelling user voting intention in social media is an important research area, with applications in analysing electorate behaviour, online political campaigning and advertising. Previous approaches mainly focus on predicting national general elections, which are regularly scheduled and where data of past results and opinion polls are available. However, there is no evidence of how such models would perform during a sudden vote under time-constrained circumstances. That poses a more challenging task compared to traditional elections, due to its spontaneous nature. In this paper, we focus on the 2015 Greek bailout referendum, aiming to nowcast on a daily basis the voting intention of 2,197 Twitter users. We propose a semi-supervised multiple convolution kernel learning approach, leveraging temporally sensitive text and network information. Our evaluation under a real-time simulation framework demonstrates the effectiveness and robustness of our approach against competitive baselines, achieving a significant 20% increase in F-score compared to solely text-based models.

description: L’opera della poetessa francese Valérie Rouzeau può essere considerata un esempio di scrittura hors du livre, che “protende” verso l’altro. Allo stesso tempo individuale e collettiva, la poesia di Rouzeau affonda nell’esperienza esistenziale e sconfina dai sentieri battuti. L’intento di questo contributo è di riflettere, alla luce di alcune considerazioni sulla “voce”, sulla transitività della parola poetica e sulla sua funzione performativa, come pure su quella consistenza sonora che non separa il linguaggio dal corpo ed è capace di interagire con il destinatario prescindendo dal mezzo di cui si serve.

The work of French poet Valérie Rouzeau can be regarded as an example of writing hors du livre, which 'leans' towards the other. At once individual and collective, Rouzeau's poetry sinks into existential experience and strays from the beaten track. The aim of this contribution is to reflect, in the light of some considerations on the "voice", on the transitivity of the poetic word and its performative function, as well as on that sound consistency that does not separate language from the body and is capable of interacting with the recipient regardless of the medium it uses.

Uncovering the Sources of Cross-border Market Segmentation: Evidence from the EU and the US

description: We develop a new approach to measure the sources of cross-border goods market segmentation. Our cost-of-living approach uncovers the relative importance of price and product availability differences, while accounting for taste differences. We implement our methodology on regionally disaggregated consumer goods data in the EU and US. The analysis reveals that price, and especially, product availability differences are much larger between than within European countries, and are only marginally larger between than within US states. Our findings imply that US states are geographically integrated, whereas EU countries remain segmented, due to trade frictions that mainly relate to fixed costs.

description: We study contributions of supersymmetric CP phases to the CP violation $ε'/ε$ in models with asymmetric $A$-matrices. We consider asymmetric $A$-matrices, which are obtained from string-inspired supergravity. We show that a certain type of asymmetry of $A$-matrices enhances supersymmetric contributions to the CP violation $ε'/ε$ and the supersymmetric contribution to $ε'/ε$ can be of order of the KTeV result, $ε'/ε\sim 10^{-3}$.

An ALMA view of the first galaxies

description: The most intriguing question of modern extra-galactic astronomy is to locate and study the first galaxies in order to determine when they emerged from the dark ages, what are their physical properties and what role do they play in governing the transition of intergalactic hydrogen from a neutral state to one that is ionised. Measures of the optical depth of electron scattering by the Planck satellite indicates this `cosmic reionisation’ was a fast process occurring relative late over the redshift interval 12 < z < 6. Combining Hubble and Spitzer Space Telescopes data allowed to identify more than a thousand of galaxies in the epoch of reionisation and to constrain the evolution of their number densities across cosmic time. The arrival of ALMA in 2012 opened a new window to explore the physical properties of these very high-redshift galaxies. First, the detection of FIR emission lines, such as [OIII]88micron, [CII]158micron or [NII]122 microns, allows to measure the spectroscopic redshift of some of the most distant galaxies currently known and to constrain the properties of their ISM (ionised, neutral and molecular gas). Furthermore, combining data from HST, Spitzer and ALMA we can get a first estimate of when the first galaxies appeared in the early Universe, and then constrain the so-called Cosmic Dawn. In this talk, I will present several results on z>8 galaxies combining Hubble, Spitzer and ALMA data.

description: Dynamics of the 1D electron transport between two reservoirs are studied based on the inhomogeneous Tomonaga- Luttinger Liquid (ITLL) model in the case when the effect of the electron backscattering on the impurities is negligible. The inhomogeneities of the interaction lead to a charge wave reflection. This effect supposes a special behavior of the transport characteristics at the microwave frequencies. New features are predicted in the current noise spectrum and in the a.c. current- frequency dependence. Knowledge of them may be very useful to identify experimental setup with the one specified by the ITLL model.

description: We employ data from precision electroweak tests and collider searches to derive constraints on the possibility that weak-singlet fermions mix with the ordinary Standard Model fermions. Our findings are presented within the context of a theory with weak-singlet partners for all ordinary fermions and theories in which only third-generation fermions mix with weak singlets. In addition, we indicate how certain results can be applied more widely in theories containing exotic fermions.
