description: The increasing co-movements between world oil and food prices in the 2000s has prompted interest in the transmission mechanism among markets. This research investigates integration and price transmission of some important agricultural commodities traded in market area that includes United States and Italy for a period spanning from January 1999 to May 2012. The hypothesis of market integration is verified for crude oil and three agri-commodities wheat, corn and soybean in Italy and US. They are selected for their market relevance due to growingly demand diversified in food, feed and fuel; wheat for its higher accounting for much of the world food consumption. It is hypothesized that US and Italy agricultural markets are integrated by a consistent volume of trading and by the recognized role of the CBT price signals transmitted to the Italian agri-commodity markets. This study extends the knowledge about the oil–agricultural commodity price transmission dynamics from international (US) to domestic market (Italy).The time series analysis is used to test the structural breaks, the co-integration and price transmission and the causality. Results suggest: i)t for the US markets the evidence of market integration between crude oil and US agri-commodity prices with non linear causality direction going from oil to agri-commodity prices; ii) the integration between US and Italian agricultural markets, with no clear evidence of causality between oil and Italian agricommodities, while there is the evidence of linear causality going from US to Italian agricultural markets. The conclusion is a presence of causality going from Oil to US agri-markets and from US agri-markets to the Italian ones These information can be useful both for investors and policy makers interested in the knowledge about the nature of price movement in the international arena the close market integration and price transmissions with consequence for co-movement ,inherent dynamic market relationship, speed of adjustment, consequences of t price support policies. The agricultural policies in different countries may be organized to countervail the destabilizing effect of the oil price movement in disrupting the world market equilibrium by arbitraging the market condition to return to a situation of competitive pricing behaviour.

description: Ferroic materials are well known to exhibit heterogeneity in the form of domain walls. Understanding the properties of these boundaries is crucial for controlling functionality with external stimuli and for realizing their potential for ultra-low power memory and logic devices as well as novel computing architectures. In this work, we employ synchrotron-based near-field infrared nano-spectroscopy to reveal the vibrational properties of ferroelastic (90$^\circ$ ferroelectric) domain walls in the hybrid improper ferroelectric Ca$_3$Ti$_2$O$_7$. By locally mapping the Ti-O stretching and Ti-O-Ti bending modes, we reveal how structural order parameters rotate across a wall. Thus, we link observed near-field amplitude changes to underlying structural modulations and test ferroelectric switching models against real space measurements of local structure. This initiative opens the door to broadband infrared nano-imaging of heterogeneity in ferroics.

description: We study the performance over the last fifteen years of exports of typical, Made in Italy agri-food products. First, we estimate the aggregate elasticities of exports values with respect to world imports, export prices and the prices applied by our competitors. Second, we show that aggregate estimates hide very different values of the elasticities at the single product level. Third, we calculate an index of sophistication for each Made in Italy agri-food exports, capturing its position in the different layers of world supply, showing that Made in Italy agri-food exports are shifting towards higher levels of sophistication. Finally, we compare the elasticities with the changes in sophistication. Our results show that the strategy of Italian exporters varies according to the type of product and to the degree of market completion. In some cases, Italian exporters contrast increasing world competition by raising the quality of their products or their sophistication content; in other cases, price competition is chosen , by keeping AUVs at lower levels than those of our competitors. But in nearly all cases, these strategies are successful in allowing Italy to defend and sometimes even to increase its world market shares, in spite of a growing world competition.

description: Formation of the Producers Export Company (PEC) in 1958 was a first attempt by grain cooperatives to develop an export merchandising program. PEC's nationwide membership had different export needs and financial resources which imposed constraints on PEC's strategy and operations. A lack of consensus by the directors prevented them from effectively adapting and changing PEC's methods of operation. This historical report explores the development of PEC and analyzes reasons for its termination in 1969.

description: The cosmological propagation of tensor perturbations is studied in the context of parity-violating extensions of the symmetric teleparallel equivalent of General Relativity theory. This non-Riemannian formulation allows for a wider variety of consistent extensions than the metric formulation of gravity theory. It is found that while many of the possible quadratic terms do not influence the propagation of the gravitational waves, a generic modification predicts a signature that distinguishes the left- and right-handed circular polarizations. The parameters of such modifications can be constrained stringently because the propagation speed of the gravitational waves is scale-dependent and differs from the speed of light.

description: Pulse production in the United States has become geographically specific and concentrated, and the marketing channels for pulses have changed dramatically over the past 30 years. The most marked change has be~n the growth of large proprietary marketing firms which are vertically integrated as national packagers and exporters, and procure directly from pulse producers through their own elevators. Farmer cooperatives as a whole have been unable to effectively countervail this growth in market concentration. Cooperatives do, 'however, have the potential to counteract their competition's position by pooling pulses, merging regional marketing agencies into a single national cooperative marketing agency in common, and/or by packaging, canning and exporting pulses themselves.

Photon polarisation entanglement from distant dipole sources

description: It is commonly believed that photon polarisation entanglement can only be obtained via pair creation within the same source or via postselective measurements on photons that overlapped within their coherence time inside a linear optics setup. In contrast to this, we show here that polarisation entanglement can also be produced by distant single photon sources in free space and without the photons ever having to meet, if the detection of a photon does not reveal its origin -- the which way information. In the case of two sources, the entanglement arises under the condition of two emissions in certain spatial directions and leaves the dipoles in a maximally entangled state.

description: We study heat conduction mediated by longitudinal phonons in one dimensional disordered harmonic chains. Using scaling properties of the phonon density of states and localization in disordered systems, we find non-trivial scaling of the thermal conductance with the system size. Our findings are corroborated by extensive numerical analysis. We show that a system with strong disorder, characterized by a `heavy-tailed' probability distribution, and with large impedance mismatch between the bath and the system satisfies Fourier's law. We identify a dimensionless scaling parameter, related to the temperature scale and the localization length of the phonons, through which the thermal conductance for different models of disorder and different temperatures follows a universal behavior.

On higher-order corrections in M theory
Creators: name: Howe, P. S.
name: Tsimpis, D.
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A theoretical analysis of higher-order corrections to D=11 supergravity is given in a superspace framework. It is shown that any deformation of D=11 supergravity for which the lowest-dimensional component of the four-form $G_4$ vanishes is trivial. This implies that the equations of motion of D=11 supergravity are specified by an element of a certain spinorial cohomology group and generalises previous results obtained using spinorial or pure spinor cohomology to the fully non-linear theory. The first deformation of the theory is given by an element of a different spinorial cohomology group with coefficients which are local tensorial functions of the massless supergravity fields. The four-form Bianchi Identities are solved, to first order and at dimension $-{1/2}$, in the case that the lowest-dimensional component of $G_4$ is non-zero. Moreover, it is shown how one can calculate the first-order correction to the dimension-zero torsion and thus to the supergravity equations of motion given an explicit expression for this object in terms of the supergravity fields. The version of the theory with both a four-form and a seven-form is discussed in the presence of the five-brane anomaly-cancelling term. It is shown that the supersymmetric completion of this term exists and it is argued that it is the unique anomaly-cancelling invariant at this dimension which is at least quartic in the fields. This implies that the first deformation of the theory is completely determined by the anomaly term from which one can, in principle, read off the corrections to all of the superspace field strength tensors.

Neutrinos and gamma-rays of hadronic origin from AGN jets

name: Dermer, C. D.

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We discuss the fluxes of high energy neutrinos and gamma-rays expected from AGNs if hadrons can be effectively accelerated to ultra-high energies by their relativistic jets, as currently believed. Fluxes of multi-TeV neutrinos detectable by $km$-scale detectors like IceCube could be expected from powerful blazars where strong accretion-disk radiation is present in the AGN cores. Gamma-ray fluxes of hadronic origin can be important for flares in the compact jets of these sources up to GeV energies, but they will be insignificant for BL Lac objects. Production of UHE neutral beams composed of neutrons and gamma-rays can drive straight collimated jets in the intergalactic medium on multi-kpc scales, which could be resolved by the Chandra X-ray observatory. While we do not expect any significant neutrino flux from these large-scale jets, we predict gamma-rays of synchrotron origin in the energy range from sub-GeV up to TeV energies, which would be detectable by GLAST and ground-based gamma-ray telescopes.

In 1997 each American consumed, on average, 81 pounds more of commercially grown vegetables the.n in 1970; 65 pounds more of grain products; 57 pounds more of fruit; 32 pounds more of caloric sweeteners; 13 pounds more of total red meat, poultry, and fish (boneless, trimmed equivalent); 17 pounds more of cheese; 13 pounds more of added fats and oils; 3 gallons more of beer; 70 fewer eggs; 10 gallons less of coffee; and 7 gallons less of milk. Retail food prices, as measured by the Consumer Price Index (CPI), increased 2.6 percent in 1997. Food price inflation in 1997 was higher than the overall increase in the CPI for all goods and services (2.3 percent) for the third consecutive year. Americans spent $715 billion for food in 1997 and another $95 billion for alcoholic beverages. Away-from-home meals and snacks captured 45 percent ofthe U.S. food dollar in 1997, up from 39 percent in" 1980 and 34 percent in 1970. The percentage of disposable personal income spent on food declined from 13.8 percent in 1970 to 10.7 percent in 1997.

description: Characterizing stellar convection in multiple dimensions is a topic at the forefront of stellar astrophysics. Numerical simulations are an essential tool for this task. We present an extension of the existing numerical tool-kit A-MaZe that enables such simulations of stratified flows in a gravitational field. The finite-volume based, cell-centered, and time-explicit hydrodynamics solver of A-MaZe was extended such that the scheme is now well-balanced in both momentum and energy. The algorithm maintains an initially static balance between gravity and pressure to machine precision. Quasi-stationary convection in slab-geometry preserves gas energy (internal plus kinetic) on average despite strong local up- and down-drafts. By contrast, a more standard numerical scheme is demonstrated to result in substantial gains of energy within a short time on purely numerical grounds. The test is further used to point out the role of dimensionality, viscosity, and Rayleigh number for compressible convection. Applications to a young sun in 2D and 3D, covering a part of the inner radiative zone as well as the outer convective zone, demonstrate that the scheme meets its initial design goal. Comparison with results obtained for a physically identical setup with a time-implicit code show qualitative agreement.

description: A TeV scale electroweak particle is a well motivated candidate for the dark matter (DM) of our Universe. Yet such a particle may only be detectable using indirect detection instruments sensitive to TeV-scale gamma rays that can result from dark matter annihilations. We present a mock analysis of the sensitivity for the present ground-based Cherenkov telescope array H.E.S.S. (High Energy Spectroscopic System) to detect TeV scale DM in the Galactic Center region. The work combines next-to-leading-logarithmic order calculations for the annihilation photon spectrum, as well as a comprehensive treatment of detector effects and expected backgrounds. Forecast limits on the sensitivity of H.E.S.S. have been derived across the important TeV mass range, assuming different DM density profiles and focusing on the canonical WIMP dark matter candidate Wino.These limits test our present and future ability to probe the predicted thermal cross section for some of the most promising DM candidates that could be discovered in the coming decade.

description: A family of cosmological solutions with $(n+1)$ Ricci-flat spaces in the theory with several scalar fields and multiple exponential potential is obtained when coupling vectors in exponents obey certain relations. Two subclasses of solutions with power-law and exponential behaviour of scale factors are singled out. It is proved that power-law solutions may take place only when coupling vectors are linearly independent and exponential dependence occurs for linearly dependent set of coupling vectors. A subfamily of solutions with accelerated expansion is singled out. A generalized isotropization behaviours of certain classes of general solutions are found. In quantum case exact solutions to Wheeler-DeWitt equation are obtained and special "ground state" wave functions are considered.

description: We consider a Dirichlet to Neumann operator $\mathcal{L}_a$ arising in a model for water waves, with a nonlocal parameter $a\in(-1,1)$. We deduce the expression of the operator in terms of the Fourier transform, highlighting a local behavior for small frequencies and a nonlocal behavior for large frequencies. We further investigate the $ Γ$-convergence of the energy associated to the equation $ \mathcal{L}_a(u)=W'(u) $, where $W$ is a double-well potential. When $a\in(-1,0]$ the energy $Γ$-converges to the classical perimeter, while for $a\in(0,1)$ the $Γ$-limit is a new nonlocal operator, that in dimension $n=1$ interpolates the classical and the nonlocal perimeter.

description: Radiative corrections to the lifetime and angular correlation coefficients of neutron beta-decay are evaluated in effecitive field theory. We also evaluate the lowest order nucleon recoil corrections, including weak-magnetism. Our results agree with those of the long-range and model-independent part of previous calculations. In an effective theory the model-dependent radiative corrections are replaced by well-defined low-energy constants. The effective field theory allows a systematic evaluation of higher order corrections to our results to the extent that the relevant low-energy constants are known.

Periplaneta americana

description: 23. Periplaneta americana (Linnaeus) (Fig. 19)
 Blatta americana Linnaeus 1758: 424; America.
 Diagnosis. Adults 27–38 mm, with full tegmina in both sexes; elongate oval, reddish-brown; pronotum bicolored, disc with yellow encircling a large, irregular, central, reddish-brown area that is sometimes weakly divided into two; outer basal margin of tegmina without a contrasting yellow stripe; supra-anal plate sub-triangular, elongate, strongly bilobed, semi-transparent; cerci slender, almost as long as mid tarsi, apical 1/2 (female) or 1/3 (male) articles longer than broad. Nymphs are shades of brown without yellow spots or bands.
 Comments. Cosmopolitan spread has produced multiple synonyms for Periplaneta americana. This edificarian pest is easily distinguished from another widespread congener P. australasiae (Species 24), by the tegmina color pattern. This is a common species on Guana Island; it is a nocturnal ground-dweller; individuals scurried around fallen tree trunks and rocks behind the hotel area (Table 1). Familiarity and abundance explain the fact that few specimens were collected for island records. Ledru (1810) first reported it from St. Thomas and St. Croix, and Lazell (2005) from Guana Island. A local BVI pest control agent has confirmed its presence in major edificarian habitats on Virgin Gorda and Tortola (J. Egelhoff, pers. comm. 24.X.2011). It is herein recorded for the first time on Anegada and Little Thatch of BVI, and St. John of USVI, in addition to other previous records on St. Croix, St. Thomas, Puerto Rico, and other Antillean islands (Shelford 1910, Princis 1966).

description: Given an action of a reductive group on a normal variety, we construct all invariant open subsets admitting a good quotient with a quasiprojective or a divisorial quotient space. Our approach extends known constructions like Mumford's Geometric Invariant Theory. We obtain several new Hilbert-Mumford type theorems, and we extend a projectivity criterion of Bialynicki-Birula and Swiecicka for varieties with semisimple group action from the smooth to the singular case.

description: We calculate the quantum phase diagram of an extended Falicov-Kimball model for one and two-dimensional systems in the intermediate coupling regime. Even though some features of the phase diagram are obtained analytically, the main results are calculated with a constrained path Monte Carlo technique. We find that this regime is dominated by a Bose-Einstein condensation of excitons with a built-in electric polarization. The inclusion of a finite hybridization between the bands removes the condensate but reinforces the ferroelectricity.
Nonlinear Spectroscopy and All-Optical Switching of Femtosecond Soliton Molecules

description: The emergence of confined structures and pattern formation are exceptional manifestations of concurring nonlinear interactions found in a variety of physical, chemical and biological systems[1]. Optical solitons are a hallmark of extreme spatial or temporal confinement enabled by a variety of nonlinearities. Such particle-like structures can assemble in complex stable arrangements, forming "soliton molecules"[2,3]. Recent works revealed oscillatory internal motions of these bound states, akin to molecular vibrations[4-8]. These observations beg the question as to how far the "molecular" analogy reaches, whether further concepts from molecular spectroscopy apply in this scenario, and if such intra-molecular dynamics can be externally driven or manipulated. Here, we probe and control such ultrashort bound-states in an optical oscillator, utilizing real-time spectroscopy and time-dependent external perturbations. We introduce two-dimensional spectroscopy of the linear and nonlinear bound-state response and resolve anharmonicities in the soliton interaction leading to overtone and sub-harmonic generation. Employing a non-perturbative interaction, we demonstrate all-optical switching between distinct states with different binding separation, opening up novel schemes of ultrafast spectroscopy, optical logic operations and all-optical memory.

description: We investigate B-type topological Landau-Ginzburg theory with one variable, with D2-brane boundary conditions. We find that the allowed brane configurations are determined in terms of the possible factorizations of the superpotential, and compute the corresponding open string chiral rings. These are characterized by bosonic and fermionic generators that satisfy certain relations. Moreover we show that the disk correlators, being continuous functions of deformation parameters, satisfy the topological sewing constraints, thereby proving consistency of the theory. In addition we show that the open string LG model is, in its content, equivalent to a certain triangulated category introduced by Kontsevich, and thus may be viewed as a concrete physical realization of it.

Dynamical density functional theory and its application to spinodal decomposition

description: We present an alternative derivation of the dynamical density functional theory for the one body density profile of a classical fluid developed by Marconi and Tarazona [J. Chem. Phys., 110, 8032 (1999)]. Our derivation elucidates further some of the physical assumptions inherent in the theory and shows that it is not restricted to fluids composed of particles interacting solely via pair potentials; rather it applies to general, multi-body interactions. The starting point for our derivation is the Smoluchowski equation and the theory is therefore one for Brownian particles and as such is applicable to colloidal fluids. In the second part of this paper we use the dynamical density functional theory to derive a theory for spinodal decomposition that is applicable at both early and intermediate times. For early stages of spinodal decomposition our non-linear theory is equivalent to the (generalised) linear Cahn-Hilliard theory, but for later times it incorporates coupling between different Fourier components of the density fluctuations (modes) and therefore goes beyond Cahn-Hilliard theory. We describe the results of calculations for a model (Yukawa) fluid which show that the coupling leads to the growth of a second maximum in the density fluctuations, at a wavenumber larger than that of the main peak.

description: We study the dependence of the ground state energy on an applied Aharonov-Bohm flux $Φ$ for the Luttinger model with large momentum scattering. Employing the method of finite size bosonization, we show that for systems with a spin gap but with gapless charge degrees of freedom, the ground state energy has an exact period of $hc/2e$, i. e. {\em half} a flux quantum, in the limit of large system size $L$. Finite size corrections are found to vanish exponentially in $L$. This behavior is contrasted to that of the spin gapless case, for both even and odd particle number. Generalizations to finite temperature are also discussed.

description: The recently measured inclusive electron-proton cross section in the nucleon resonance region, performed with the CLAS detector at the Thomas Jefferson Laboratory, has provided new data for the nucleon structure function $F_2$ with previously unavailable precision. In this paper we propose a description of these experimental data based on a Regge-dual model for $F_2$. The basic inputs in the model are nonlinear complex Regge trajectories producing both isobar resonances and a smooth background. The model is tested against the experimental data, and the $Q^2-$ dependence of the moments is calculated. The fitted model for the structure function (inclusive cross section) is a limiting case of the more general scattering amplitude equally applicable to deeply virtual Compton scattering (DVCS). The connection between the two is discussed.
