description: The hadronic decays eta -> pi pi pi, eta-prime -> pi pi pi and eta-prime -> eta pi pi are investigated within a U(3) chiral unitary approach. Final state interactions are included by deriving the effective s-wave potentials for meson meson scattering from the chiral effective Lagrangian and iterating them in a Bethe-Salpeter equation. With only a small set of parameters we are able to explain both rates and spectral shapes of these decays.

description: We use a mixture regression model to identify segmentation in the Israeli labor market, and propose a new method for assigning workers to simulated segments. We identified a lowwage segment and a high-wage segment, as well as a third segment with a large wage variability that we interpret as “noisy” observations. We found quantitatively small but qualitatively reasonable differences in workers’ characteristics between the low-wage and high-wage segments, while the coefficient differences were much larger, indicating that much of the wage disparity in Israel is due to unobserved factors rather than to observable characteristics. Some policy-relevant insights are derived.

description: Let K be a number field containing the group of n-th roots of unity and S a set of primes of K including all those dividing n and all real archimedean places. We consider the cup product on the first Galois cohomology group of the maximal S-ramified extension of K with coefficients in n-th roots of unity, which yields a pairing on a subgroup of the multiplicative group of K containing the S-units. In this general situation, we determine a formula for the cup product of two elements which pair trivially at all local places. Our primary focus is the case that K is the cyclotomic field of p-th roots of unity for n = p an odd prime and S consists of the unique prime above p in K. We describe a formula for this cup product in the case that one element is a p-th root of unity. We explain a conjectural calculation of the restriction of the cup product to p-units for all p < 10,000 and conjecture its surjectivity for all p satisfying Vandiver's conjecture. We prove this for the smallest irregular prime p = 37, via a computation related to the Galois module structure of p-units in the unramified extension of K of degree p. We describe a number of applications: to a product map in K-theory, to the structure of S-class groups in Kummer extensions of K, to relations in the Galois group of the maximal pro-p extension of K unramified outside p, to relations in the graded Z_p-Lie algebra associated to the representation of the absolute Galois group of Q in the outer automorphism group of the pro-p fundamental group of P^1 minus three points, and to Greenberg's pseudo-nullity conjecture.

Farm Size Inequality in Israel: 1971-1995

description: farm size inequality is a natural outcome of farm specialization and the advantages of scale economies for more successful farmers, but it could weaken the common interests among farmers and thus their political power. This is especially true for farms that are organized in cooperatives, such as the Israeli Moshav. The weakening of cooperation in the Moshav since the 1980s has contributed to increased farm diversity in both size and specialization, and this in turn further weakened the cooperatives and reduced their ability to use political power to promote common interests. The purpose of this paper is to analyze the changes in farm size inequality among family farms in the Moshav sector between 1971 and 1995 and their determinants. We take advantage of two decomposition methodologies that have been used previously to analyze income inequality: decomposition of inequality by income sources and by regression. Each of these methods is applied to two inequality indices: the Gini coefficient and the CV index. Farm size is measured by the normative value of output, and outputs of different farm products represent different income sources. We use data from the two recent censuses of agriculture in Israel, 1971 and 1981, and subsequent 1995 farm survey that was based on the census questionnaires. We find that farm size inequality has increased over the years. The decomposition by type of farm products shows that farm size inequality stems primarily from size inequality within poultry and beef farms. The decomposition by regression attributed most farm size inequality to capital stock and unobserved factors. While the importance of capital stock diminished considerably over the years, the slack was not captured by other explanatory variables but rather by unobserved factors, so that over the years it became more difficult to describe and explain farm size inequality.

description: The exact perturbation approach is used to derive the (seven) elementary correlation lengths and related mass gaps of the two-dimensional dilute A$_4$ lattice model in regime 2- from the Bethe ansatz solution. This model provides a realisation of the integrable $ϕ(1,2)$ perturbation of the c=7/10 conformal field theory, which is known to describe the off-critical thermal behaviour of the tricritical Ising model. The E$_7$ masses predicted from purely elastic scattering theory follow in the approach to criticality. Universal amplitudes for the tricritical Ising model are calculated.

description: A pot experiment was conducted in sandy clay loam saline-sodic soil to assess the effects of farm yard manure (FYM), municipal solid waste (MSW) composts and gypsum application on nitrate leaching, soil chemical properties and crop productivity under rice-wheat cropping system. It also aims at establishing the correlation between soil phsico-chemical properties and yield response using principle component analysis and Pearson correlation analysis. The MSW was decomposed aerobically, an-aerobically and co-composted. Maximum nitrate leaching was observed during rice (75.9 mg L−1) and wheat (37.2 mg L−1) with an-aerobically decomposed MSW as compared with control treatment. Results revealed a decrease in soil pH (−6.95% and −8.77%), electrical conductivity (EC) (−48.13% and −51.04%), calcium carbonate (CaCO3) (−40.30% and −48.96%), and sodium adsorption ratio (SAR) (−40.27% and −45.98%) with an-aerobically decomposed MSW compost during rice and wheat, respectively. In this treatment, organic matter (OM) (93.55% and 121.51%) and cation exchange capacity (CEC) (19.31% and 31.79%) were the highest as compared with control treatment during rice and wheat, respectively. Rice and wheat growth were significantly (p≤ 0.05) increased by an-aerobically decomposed MSW followed by co-compost, aerobically decomposed MSW, FYM, gypsum and control. Furthermore, Pearson correlation coefficients predicted significant positive correlation of yield with soil OM, and CEC while inverse relationship was observed with EC, pH, CaCO3, and nitrogen use efficiency. Soil amelioration with organic and gypsum amendments was further confirmed with principal component analysis. This study has proved an-aerobically decomposed MSW as an effective solution for MSW disposal, thereby improving soil chemical properties and crop productivity from sandy clay loam saline-sodic soil.

description: The industrialization of agriculture is associated with tighter supply chains where vertical coordination between farmers and processors is facilitated by the use of agricultural contracts. An overview is provided on the recent trends in the use and structure of agricultural contracts followed by an examination of how the competition among processors may affect agricultural contracts. Many reasons exist for using agricultural contracts, including improved risk management and reduced transaction cost. On the other hand, the growing use of agricultural contracts and processor concentration raises concerns that processors may exercise market power, for example by offering lower contract prices in absence of local competition. Previous studies using the new empirical industrial organization models show that processing industries are not perfectly competitive but the price distortions are very small. The focus here is on examining price competition from a farmer’s instead of an industry’s point of view. Recent studies using farm-level data that show that the absence of other contractors or spot markets in producers’ areas does not lead to statistically significant price differences in agricultural contracts for most commodities. These findings provide evidence that most agricultural processors do not exercise market power by reducing prices when other local buyers are not available. Therefore, the recent trends of industrialization and increased vertical coordination in agriculture are likely occurring for reasons other than processors exercising market power.

description: It is now experimentally possible to entangle thousands of qubits, and efficiently measure each qubit in parallel in a distinct basis. To fully characterize an unknown entangled state of $n$ qubits, one requires an exponential number of measurements in $n$, which is experimentally unfeasible even for modest system sizes. By leveraging (i) that single-qubit measurements can be made in parallel, and (ii) the theory of perfect hash families, we show that all $k$-qubit reduced density matrices of an $n$ qubit state can be determined with at most $e^{\mathcal{O}(k)} \log^2(n)$ rounds of parallel measurements. We provide concrete measurement protocols which realize this bound. As an example, we argue that with current experiments, the entanglement between every pair of qubits in a system of 1000 qubits could be measured and completely characterized in a few days. This corresponds to completely characterizing entanglement of nearly half a million pairs of qubits.

description: In this paper we formulate the nonlocal dbar problem dressing method of Manakov and Zakharov [28, 29, 27] for the 4 scaling classes of the 1+1 dimensional Kaup--Broer system [7, 13]. The method for the 1+1 dimensional Kaup--Broer systems are reductions of a method for a complex valued 2+1 dimensional completely integrable partial differential equation first introduced in [23]. This method allows computation of solutions to all cases of the Kaup--Broer system. We then consider the case of non-capillary waves with usual gravitational forcing, and use the dressing method to compute N-soliton solutions and more general solutions in the closure of the N-soliton solutions in the topology of uniform convergence in compact sets called primitive solutions. These more general solutions are an analogue of the solutions derived in [11, 30, 31] for the KdV equation. We derive dressing functions for finite gap solutions. We compute counter propagating dispersive shockwave type solutions numerically.

description: We show how the tree level unitarity violations of compactified extra dimensional extensions of the Standard Model become much stronger when the scalar sector is included in the bulk. This effect occurs when the couplings are not suppressed for larger Kaluza-Klein levels, and could have relevant consequences for the phenomenology of the next generation of colliders. We also introduce a simple and generic formalism to obtain unitarity bounds for finite energies, taking into account coupled channels including the towers of Kaluza-Klein excitations.

description: In this work, we report on the synthesis and magnetic properties of a series of double perovskites Ln$_2$ZnIrO$_6$ with Ln = Nd, Sm, Eu & Gd. These compounds present new examples of the rare case of double perovskites (general formula A$_2$BB'O$_6$) with a magnetic 4f -ion on the A-site in combination with the strongly spin-orbit coupled 5d-transition metal ion Ir$^{4+}$ on the B-sublattice. We discuss the impact of different rare earths on the macroscopic magnetic properties. Gd$_2$ZnIrO$_6$ and Eu$_2$ZnIrO$_6$ show weak canted antiferromagnetic order below T$_N$ = 23 K and T$_N$ = 12 K, respectively. Sm$_2$ZnIrO$_6$ orders antiferromagnetically at T$_N$ = 13 K. Nd$_2$ZnIrO$_6$ exhibits complex magnetic properties with strong field dependence ranging from a two-step behavior at H = 0.01 T to an antiferromagnetic ground state at intermediate external fields and a spin-flop phase at H$\geq$4 T, which suggests complex interplay between Nd$^{3+}$ and Ir$^{4+}$ . To further shed light on this magnetic interaction, the magnetic structure of Nd$_2$ZnIrO$_6$'s ground state is examined via neutron powder diffraction.

description: U.S. decoupled direct payments, paid to farm operators based on historic yields and base acreage under the 2002 Farm Bill, may alter a farmer’s access to credit or his ability to meet debt servicing obligations. Data from the U.S. Department of Agriculture (USDA) Agricultural Resource Management Survey (ARMS) for the years 2005, 2006 and 2007 are used. We find a positive significant relationship between the level of direct payments (in dollars) and the term debt coverage ratio for experienced farmers, suggesting that direct payments improve repayment capacity. However, this relationship is not significant for beginning farmers. We also find a negative significant relationship between the number of base acres and the current ratio for experienced farmers, while this relationship lacks significance for beginning farmers. We provide evidence that decoupled direct payments impact a farmer’s liquidity and repayment capacity. This paper also contributes to the growing body of research investigating the mechanisms by which decoupled payments have the potential to distort current production.

description: Steganography is an art of obscuring data inside another quotidian file of similar or varying types. Hiding data has always been of significant importance to digital forensics. Previously, steganography has been combined with cryptography and neural networks separately. Whereas, this research combines steganography, cryptography with the neural networks all together to hide an image inside another container image of the larger or same size. Although the cryptographic technique used is quite simple, but is effective when convoluted with deep neural nets. Other steganography techniques involve hiding data efficiently, but in a uniform pattern which makes it less secure. This method targets both the challenges and make data hiding secure and non-uniform.

description: We consider a nonlinear Robin problem driven by the $p$-Laplacian. In the reaction we have the competing effects of two nonlinearities. One term is parametric, strictly $(p-1)$-sublinear and the other one is $(p-1)$-linear and resonant at any nonprincipal variational eigenvalue. Using variational tools from the critical theory (critical groups), we show that for all large enough values of parameter $λ$ the problem has at least five nontrivial smooth solutions.

 Halosydna patagonica Kinberg, 1856: 385.    Diagnosis
 Body thin, sub-rectangular, with 36 segments. Prostomium bilobed, without cephalic peaks; two pairs of small eyes, both pairs on posterior half of prostomium; three antennae, median antenna with ceratophore inserted frontally, with long, thick, style, subdistally expanded and tip filiform, surface not papillose; lateral antennae with ceratophores inserted terminally as prolongations of prostomium, at same level of ceratophore of median antenna, style of similar shape to median antenna. Two palps. Pharynx with nine pairs of marginal papillae and two pairs of hard jaws. Tentacular segment not visible dorsally, tentaculophores lateral to prostomium, tentacular cirri similar to antennae. Body with 18 pairs of elytra on segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 28, 30, 31, 33. Posteriormost three segments with dorsal cirri. Elytra imbricated; margins with or without papillae; surface with papillae and / or tubercles (sclerotized or vesicular). Elytrophores rounded. Parapodia biramous. Notopodia shorter than neuropodia. Neuropodia distally truncated, with small rounded lobe near acicula tip. Dorsal cirri subdistally expanded and distally with filiform tip; cirrophore basally expanded. Dorsal tubercle inconspicuous. Ventral cirri shorter than neuropodia, tapering to fine tip.
Notochaetae shorter than neurochaetae; with rows of spines; less abundant than neurochaetae; the smaller curved, with blunt tip, remaining ones slender tapering to capillary tips. Neurochaetae with rows of spines on upper region, tips entire or bidentate. Anus dorsal, between segments 35–36. Pygidium with one pair of anal cirri.   Remarks
 Members of Halosydna were described by Kinberg (1858) as having 18–21 pairs of elytra. However, all specimens examined in this study have 18 pairs, as defined by Hartman (1938). In addition, members of Halosydna species are recognized by eytral insertion: elytra of segments 27 and 28 are contiguous, also elytra of segments 30 and 31. Elytral arrangement is constant and important to confirm generic placement. Members of Halosydna have robust bodies, which neither autotomize nor lose elytra when collected or fixed. Members of all species consistently bear a small rounded lobe near the neuroacicular tip.

We study the effects of a finite sampling distance on the measured spatial persistence probability and show that both SS and FIC persistence probabilities exhibit simple scaling behavior as a function of the system size and the sampling distance. Analytical expressions for the exponents associated with the power-law decay of SS and FIC spatial persistence probabilities of the EW equation with power-law correlated noise are established and numerically verified.

description: Agribusinesses represent a fundamental link in connecting farmers with retailers and consumers, yet little research has been done to examine the historical financial performance of these food processing firms. Our research examines how publicly-traded agribusinesses perform financially compared to all firms over the period from 1961 to 2011. We utilize several indicators of company success, including financial ratios and balance sheet/income statement items, to compare agribusiness firms to all firms in the market. We perform the analysis over time and also for companies with low-, median, and high-performance. We also perform DuPont analysis to compare return on equity components between agribusinesses and all firms. We find that agribusinesses outperform at the median the sample of all firms in terms financial ratios related to profitability, liquidity, and market ratios, but have slightly lower liquidity and debt ratios. The DuPont analysis shows that the higher return on equity for agribusinesses is mostly due to higher asset turnover ratios, indicating higher operating efficiency of agribusinesses. The strong financial performance of food manufacturing agribusinesses makes them valuable companies in an investment portfolio. Our study provides a basic overview of financial ratios used to examine the financial performance of publicly-traded agribusinesses. Our findings show that agribusinesses outperform all firms in terms of key financial indicators.

description: Item response theory is a set of models and methods allowing for the analysis of binary or ordinal variables (items) that are influenced by a latent variable or latent trait—that is, a variable that cannot be measured directly. The theory was originally developed in educational assessment but has many other applications in clinical research, ecology, psychiatry, and economics. The Mokken scales have been described by Mokken (1971, A Theory and Procedure of Scale Analysis [De Gruyter]). They are composed of items that satisfy the three fundamental assumptions of item response theory: unidimensionality, monotonicity, and local independence. They can be considered nonparametric models in item response theory. Traces of the items and Loevinger’s H coefficients are particularly useful indexes for checking whether a set of items constitutes a Mokken scale. However, these indexes are not available in general statistical packages. We introduce Stata commands to compute them. We also describe the options available and provide examples of output.

description: In this paper we compute the N=1 effective low energy action for a stack of N space-time filling D3-branes in generic type IIB Calabi-Yau orientifolds with non-trivial background fluxes by reducing the Dirac-Born-Infeld and Chern-Simons actions. Specifically, we determine the Kahler potential for the excitations of the D-brane including their couplings to all bulk moduli fields. In the effective theory, N=1 supergravity is spontaneously broken by the presence of fluxes and we compute the induced soft supersymmetry breaking terms. We find an interesting structure in the resulting soft terms with generically universal soft scalar masses.

Spectroscopic and optical response of odd-frequency superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The optical response of superconductors with odd-frequency Berezinskii pairing is studied. By using a simple model with a parabolic dispersion law and a non-magnetic disorder, the spectral function, the electron density of states, and the optical conductivity are calculated for a few gap ansatzes. The spectral function and the electron density of states clearly reveal the gap for the Berezinskii pairing for the sufficiently strong frequency dependence of the order parameters. It is found that, similarly to the conventional BCS pairing, the odd-frequency gaps induce peaks in the real part of the conductivity, which, however, are sharper than in the BCS case. The magnitude and position of these peaks are determined by the frequency profile of the gap. The imaginary part of the optical conductivity for the Berezinskii pairing demonstrates sharp cusps that are absent in the case of the BCS superconductors. The corresponding results suggest that the Berezinskii pairing might allow for the optical transparency windows related to the onsets of the attenuation peaks in the real part of the conductivity. Thus, the study of the optical response not only provides an alternative way to probe the odd-frequency gaps but can reveal also additional features of the dynamic superconducting pairing.

On Yukawa quasi-unification with mu<0

description: Although recent data on the muon anomalous magnetic moment strongly disfavor the constrained minimal supersymmetric standard model with mu<0, they cannot exclude it because of theoretical ambiguities. We consider this model supplemented by a Yukawa quasi-unification condition which allows an acceptable b-quark mass. We find that the cosmological upper bound on the lightest sparticle relic abundance is incompatible with the data on the branching ratio of b-->s gamma, which is evaluated by including all the next-to-leading order corrections. Thus, this scheme is not viable.

description: A graphical representation of the pointwise confidence intervals allows a researcher to easily assess the precision of estimators. In the absence of covariates, the official command sts graph can be used to plot these intervals for the survivor function or the cumulative hazard function; however, in the presence of covariates, sts graph is insufficient. The user-written command survci can be used to plot the pointwise intervals for the survivor function after the Cox model. In this article, I describe the current and new features of survci. The new features include pointwise confidence intervals for the cumulative hazard function and the support of stratified Cox models, as well as factor variables; available as of Stata 11. I describe the methods used in calculating pointwise confidence intervals in the Cox model for both the covariate-adjusted survivor function and the covariate-adjusted cumulative hazard function. I also demonstrate the syntax of survci using Stata’s example cancer dataset, cancer.dta.

description: Hurdle models based on the zero-truncated Poisson-lognormal distribution are rarely used in applied work, although they incorporate some advantages compared with their negative binomial alternatives. I present a command that enables Stata users to estimate Poisson-lognormal hurdle models. I use adaptive Gauss–Hermite quadrature to approximate the likelihood function, and I evaluate the performance of the estimator in Monte Carlo experiments. The model is applied to the number of doctor visits in a sample of the U.S. Medical Expenditure Panel Survey.

description: We study quantum entanglement for CAR systems. Since the subsystems of disjoint regions are not independent for CAR systems, there are some distinct features of quantum entanglement which cannot be observed in tensor product systems. We show the failure of triangle inequality of von Neumann and the possible increase of entanglement degree under operations done in a local region for a bipartite CAR system.

title: Выражение подтекста в авторских телепрограммах, посвященных Великой Отечественной войне (на примере передач Эдварда Радзинского «Гитлер. Путь во власть»)

description: Подтекст на российском телевидении — явление малоизученное. Зачастую в авторских аналитических передачах с его помощью можно сделать необходимый акцент в материале, привлечь внимание к какой-то проблеме. На примере программы Эдварда Радзинского «Гитлер. Путь во власть» мы рассмотрели конкретные вербальные и невербальные способы выражения подтекста и их взаимодействие между собой. Мы убедились, что в авторских аналитических передачах подтекст играет одну из ключевых ролей. С его помощью ведущий может выразить собственное отношение к ситуации или сделать необходимый автору акцент в материале. Эдвард Радзинский умело использует популярные приемы как вербального, так и невербального подтекста, а иногда и их творческую «синергию». Наиболее частотны варианты, когда ведущий сочетает жестикуляцию, интонирование и систему пауз, превращая стандартный сценарий в «театральное действо», приковывающее внимание зрителя.

We also show that other $\, _3F_2$ and $\, _4F_3$ unresolved examples of Christol's conjecture are diagonals of rational functions. Finally we give two arguments that show that it is likely that the $\, _3F_2([1/9, 4/9, 5/9], \, [1/3,1], \, 27 \cdot x)$ function is a diagonal of a rational function.

Molecular characterization of macroscopic aerogels of single-walled carbon nanotubes

description: Single-walled carbon nanotubes (SWCNT) can be assembled into various macroscopic architectures, most notably continuous fibers and films, produced currently on a kilometer per day scale by floating catalyst chemical vapor depositionand spinning from an aerogel of CNTs. An attractive challenge is to produce continuous fibers with controlled molecular structure with respect to the diameter, chiral angle and ultimately(n,m)indices of the constituent SWCNT molecules. This work presents an extensive Raman spectroscopy and high resolution transmission electron microscopy study of SWCNT aerogels produced by the direct spinning method. By retaining the open structure of the SWCNT aerogel, we reveal the presence of both semiconducting and metallic SWCNTs and determine a full distribution of families of SWCNT grouped by optical transitions. The resulting distribution matches the chiral angle distribution obtained by electron microscopy and electron diffraction. The effect of SWCNT bundling on the Raman spectra, such as the G line shape due to plasmons activated in the far-infrared and semiconductor quenching, are also discussed. By avoiding full aggregation of the aerogel and applying the methodology introduced, rapid screening of molecular features can be achieved in large samples, making this protocol a useful analysis tool for engineered SWCNT fibers and related systems.

I show the effects of censoring on estimation results by comparing the censored Poisson model with the uncensored one.
