description: Farmers have increasingly been procuring external equity financing through either written or verbal business arrangements. Passage of the Agricultural Risk Protection Act in 2000 has resulted in widespread adoption of crop insurance among farmers. Crop insurance changes farmers’ production decisions, so that investors providing external equity may want to adjust the equity financing contract to account for these changes. This paper uses a principal-agent model to determine optimal risk sharing and incentives under crop insurance and external equity financing. Results show that with the introduction of crop insurance, the investor’s optimal equity financing contract requires that the farmer bears more risk in order to have the incentive to work hard.

Self-avoiding walks and polygons on quasiperiodic tilings

description: We enumerate self-avoiding walks and polygons, counted by perimeter, on the quasiperiodic rhombic Penrose and Ammann-Beenker tilings, thereby considerably extending previous results. In contrast to similar problems on regular lattices, these numbers depend on the chosen start vertex. We compare different ways of counting and demonstrate that suitable averaging improves converge to the asymptotic regime. This leads to improved estimates for critical points and exponents, which support the conjecture that self-avoiding walks on quasiperiodic tilings belong to the same universality class as self-avoiding walks on the square lattice. For polygons, the obtained e numeration data does not allow to draw decisive conclusions about the exponent.

description: The Higgs mode in superconductors is a scalar mode without electric or magnetic dipole moment. Thus, it is commonly believed that its excitation is restricted to a nonlinear two-photon Raman process. However, recent efforts have shown that a linear excitation in the presence of a supercurrent is possible, resulting in a new resonant enhancement at $Ω=2Δ$ with the driving light frequency $Ω$ and the energy of the Higgs mode $2Δ$. This is in contrast to the usual $2Ω= 2Δ$ resonance condition found in nonlinear third-harmonic generation experiments. In this communication, we show that such a linear excitation can still be described as an effective Raman two-photon process, with one photon at $ω=2Δ$ and one virtual photon at $ω=0$ which represents the dc supercurrent. At the same time we demonstrate that a straightforward infrared activation with a single photon excitation is negligible. Moreover, we give a general context to our theory, providing an explanation for how the excitation of the Higgs mode in both THz quench and drive experiments can be understood within a conventional difference-frequency generation or sum-frequency generation process, respectively. In such a picture, the observed new resonance condition $Ω= 2Δ$ is just a special case. With the same approach, we further discuss another recent experiment, where we find a suppression of odd order higher harmonics in the presence of a dc supercurrent.

description: Chondrocytes, the resident cells in articular cartilage, carry the burden of producing and maintaining the extracellular matrix (ECM). However, as these cells have a low proliferative capacity and are not readily replaced, chondrocyte death due to extreme forces may contribute to the pathogenesis of osteoarthritis (OA) after injury or may inhibit healing after osteochondral transplantation, a restorative procedure for damaged cartilage that requires a series of mechanical impacts to insert the graft. Consequently, there is a need to understand what factors influence the vulnerability of in situ chondrocytes to mechanical trauma. To this end, the objective of this study was to investigate how altering cell volume by different means (hydrostatic pressure, uniaxial load, and osmotic challenge with and without inhibition of regulatory volume decrease) affects the vulnerability of in situ chondrocytes to extreme mechanical forces. Using a custom experimental platform enabling testing of viable and intact murine cartilage-on-bone explants, we established a strong correlation between chondrocyte volume and vulnerability to impact injury wherein reduced volume was protective. Moreover, we found that the volume-perturbing interventions did not affect cartilage ECM mechanical properties, suggesting that their effects on chondrocyte vulnerability occurred at the cellular level. The findings of this study offer new avenues for novel strategies aimed at preventing chondrocyte loss during osteochondral grafting or to halting the progression of cell death after a joint destabilizing injury.

description: We propose the Schwinger-Dyson (SD) formalism based on lattice QCD, i.e., LQCD-based SD formalism, for the study of dynamical chiral-symmetry breaking in QCD. We extract the kernel function K(p^2) in the SD equation from the lattice data of the quark propagator in the Landau gauge. As remarkable features, we find infrared vanishing and intermediate enhancement of the kernel function K(p^2) in the SD equation. We apply the LQCD-based SD equation to thermal QCD, and calculate the quark mass function at the finite temperature. We find chiral symmetry restoration at the critical temperature T_c \sim 100MeV.

description: Heliospheric plasmas require multi-scale and multi-physics considerations. On one hand, MHD codes are widely used for global simulations of the solar-terrestrial environments, but do not provide the most elaborate physical description of space plasmas. Hybrid codes, on the other hand, capture important physical processes, such as electric currents and effects of finite Larmor radius, but they can be used locally only, since the limitations in available computational resources do not allow for their use throughout a global computational domain. In the present work, we present a new coupled scheme which allows to switch blocks in the block-adaptive grids from fluid MHD to hybrid simulations, without modifying the self-consistent computation of the electromagnetic fields acting on fluids (in MHD simulation) or charged ion macroparticles (in hybrid simulation). In this way, the hybrid scheme can refine the description in specified regions of interest without compromising the efficiency of the global MHD code.

description: The on-farm conservation and management of native grasslands, especially those that are botanically diverse or support threatened species is now an important policy issue for State and Commonwealth Governments. Economics is important to achieving public policy goals because farms ore primarily about providing a livelihood and an economic return. The results of interviews with landholders from across south-eastern Australia on farms with native grassland are reported in the paper. These exploratory findings raise many interesting points to be considered in more definitive research and in policy deve1opment. They cover the reasons native gmsslunds can Mill be found on these farms~ the place of native grass1ands in farming systems and factors likely to nffect the future of the native grasslands. Appropriate types of incentives and other policy mechanisms which may be requnred to nchieve desired conservation outcomes ate also discussed. Some suggestions are made For relevant economic resmtrch.

description: A topological group $G$ is called extremely amenable if every continuous action of $G$ on a compact space has a fixed point. This concept is linked with geometry of high dimensions (concentration of measure). We show that a von Neumann algebra is approximately finite-dimensional if and only if its unitary group with the strong topology is the product of an extremely amenable group with a compact group, which strengthens a result by de la Harpe. As a consequence, a $C^\ast$-algebra $A$ is nuclear if and only if the unitary group $U(A)$ with the relative weak topology is strongly amenable in the sense of Glasner. We prove that the group of automorphisms of a Lebesgue space with a non-atomic measure is extremely amenable with the weak topology and establish a similar result for groups of non-singular transformations. As a consequence, we prove extreme amenability of the groups of isometries of $L^p(0,1)$, $1\leq p

description: Various reconstructions of finite-dimensional quantum mechanics result in a formally real Jordan algebra A and a last step remains to conclude that A is the self-adjoint part of a C*-algebra. Using a quantum logical setting, it is shown that this can be achieved by postulating that there is a locally tomographic model for a composite system consisting of two copies of the same system. Local tomography is a feature of classical probability theory and quantum mechanics; it means that state tomography for a multipartite system can be performed by simultaneous measurements in all subsystems. The quantum logical definition of local tomography is sufficient, but it is less restictive than the prevalent definition in the literature and involves some subtleties concerning the so-called spin factors.

Solving Phase Retrieval via Graph Projection Splitting

Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: Phase retrieval with prior information can be cast as a nonsmooth and nonconvex optimization problem. We solve the problem by graph projection splitting (GPS), where the two proximity subproblems and the graph projection step can be solved efficiently. With slight modification, we also propose a robust graph projection splitting (RGPS) method to stabilize the iteration for noisy measurements. Contrary to intuition, RGPS outperforms GPS with fewer iterations to locate a satisfying solution even for noiseless case. Based on the connection between GPS and Douglas-Rachford iteration, under mild conditions on the sampling vectors, we analyze the fixed point sets and provide the local convergence of GPS and RGPS applied to noiseless phase retrieval without prior information. For noisy case, we provide the error bound of the reconstruction. Compared to other existing methods, thanks for the splitting approach, GPS and RGPS can efficiently solve phase retrieval with prior information regularization for general sampling vectors which are not necessarily isometric. For Gaussian phase retrieval, compared to existing gradient flow approaches, numerical results show that GPS and RGPS are much less sensitive to the initialization. Thus they markedly improve the phase transition in noiseless case and reconstruction in the presence of noise respectively. GPS shows sharpest phase transition among existing methods including RGPS, while it needs more iterations than RGPS when the number of measurement is large enough. RGPS outperforms GPS in terms of stability for noisy measurements. When applying RGPS to more general non-Gaussian measurements with prior information, such as support, sparsity and TV minimization, RGPS either outperforms state-of-the-art solvers or can be combined with state-of-the-art solvers to improve their reconstruction quality.

description: Today’s world is caught in great economic crisis. Liberalisation has bought many multinational companies into developing countries. Due to this the local enterprises are unable to compete with the products that are better in quality as well as low in prices. In this economic environment, the women self-help groups are building themselves up as a power to be reckoned with. In the developing world, India presents a unique opportunity and need for poverty alleviation. India’s political environment and strong economic growth over the last 10 years have put the country in a position to become the third-largest economy in the world by 2050. At the same time, India accounts for the largest share of the world’s poor with over 860 million people living on less than US$2 a day and economic development characterized by a widening income gap between the rich and poor parts of the country.Therefore a healthy banking system is essential for any economy striving to achieve good growth and yet remain stable in an increasingly global business environment. The Indian banking system, with one of the largest banking networks in the world, has witnessed a series of reforms over the past few years. In that series microfinance also exists. The unique feature of microfinance programme is that it focuses on women for development. Thus the paper focuses on microfinance & SHG’s & its impact on Women empowerment by discussing certain issues and evidences and also the role of SHG’s.
Stellar Magnetic Activity and "Butterfly Diagram" of Kepler-63

description: Context. The study of young solar type stars is fundamental for a better understanding of the magnetic activity of the Sun. As a planet in transit crosses in front of its host star, a darkspot on the stellar surface may be occulted, causing a detectable variation in the light curve. Kepler-63 is a young solar-like star withan age of only 210 Myr that exhibit photometric variations compatible with spot signatures. Since its orbiting planet is in an almostpolar orbit, different latitudes of the star can be probed by the method of spot transit mapping. Methods. A total of 150 transits of Kepler-63b were observed in the short cadence light curve, corresponding to a total duration of about 4 years. Each transit light curve was fit by a model that simulates planetary transits and allows the inclusion of starspots on the surface of the host star. This enables the physical characterisation of the spots size, intensity, and location. We determine the spot position in a reference frame that rotates with the star, and thus obtain the latitudinal distribution of the spots. Results. A total of 297 spots were fit and their sizes, intensities, and positions determined. The latitude distribution of spots exhibits a bimodality with a lack of spots around 34°. The high latitude spots dominate the magnetic cycle of Kepler-63. For a mean stellar rotation period of 5.400d, 59 spots were found at approximately the same longitude and latitude on a later transit. Conclusions. Due to the geometry of the Kepler-63 system, we were able to build a starspot "butterfly diagram". It was also possible to infer Kepler-63 differential rotation from the presence of spots at different latitudes. This star was found to rotate almost rigidly with a period of 5.400d and relative shear close to 0.01% for latitudes less than 34°, whereas the high latitudes do not follow a well behaved pattern.

description: Let $A\subset\mathbb{N}$, $α\in(0,1)$, and for $x\in\mathbb{R}$ let $e(x):=e^{2πix}$. We set $$S_{A}(α,N):=\sum_{\substack{n\in A\n\leq N}}e(nα).$$ Recently, Lambert A'Campo proposed the following question: is there an infinite non-cofinite set $A\subset\mathbb{N}$ such that for all $α\in(0,1)$ the sum $S_{A}(α,N)$ has bounded modulus as $N\to +\infty$? In this note we show that such sets do not exist. To do so, we use a theorem by Duffin and Schaeffer on complex power series. We extend our result by proving that if the sum $S_{A}(α,N)$ is bounded in modulus on an arbitrarily small interval and on the set of rational points, then the set $A$ has to be either finite or cofinite. On the other hand, we show that there are infinite non-cofinite sets $A$ such that $|S_{A}(α,N)|$ is bounded for all $α\in E\subset (0,1)$, where $E$ has full Hausdorff dimension and $\mathbb{Q}\cap (0,1)\subset E$.

description: A new approach to solve quasicrystalline atomic structures in 3-dimensional (3D) real space is presented: The atomic pair distribution function (PDF) of face centred icosahedral Ho9Mg26Zn65 [a(6D) = 2x5.18(3)A was obtained from in-house X-ray diffraction data (MoKa1). Starting with rational approximant models, derived from 1/1- and 2/1-Al-Mg-Zn, its local and medium range structure was refined (r < 27A; R = 12.9%) using the PDF data. 85% of all atoms show Frank-Kasper (FK) type coordinations. Basic structural unit is the 3-shell, 104-atom Bergman cluster (d = 15A comprising a void at its center. The clusters are interconnected sharing common edges and hexagonal faces of the 3rd shells. The remaining space is filled by some glue atoms (9% of all atoms), yielding an almost tetrahedrally close packed structure. All Ho atoms are surrounded by 16 neighbours (FK-polyhedron "P"). Most of them (89%) are situated in the 2nd shell (pentagon dodecahedron), the other act as glue atoms. As a result and as can be expected for real matter, local atomic coordinations in quasicrystals are similar compared to common crystalline intermetallic compounds. From our results, the long range quasiperiodic structure of icosahedral Mg-Zn-RE (RE = Y and some rare earths) is anticipated to be a canonical cell tiling (CCT, after Henely) decorated with Bergman clusters.

description: The Kauffman-Harary conjecture states that for any reduced alternating diagram K of a knot with a prime determinant p, every non-trivial Fox p-coloring of K assigns different colors to its arcs. We generalize the conjecture by stating it in terms of homology of the double cover of S^3 branched along a link. In this way we extend the scope of the conjecture to all prime alternating links of arbitrary determinants. We first prove the Kauffman-Harary conjecture for pretzel knots and then we generalize our argument to show the generalized Kauffman-Harary conjecture for all Montesinos links. Finally, we speculate on the relation between the conjecture and Menasco's work on incompressible surfaces in exteriors of alternating links.

Witnessing the gradual slow-down of powerful extragalactic jets: The X-ray -- optical -- radio connection

description: A puzzling feature of the {\it Chandra}--detected quasar jets is that their X-ray emission decreases faster along the jet than their radio emission, resulting to an outward increasing radio to X-ray ratio. In some sources this behavior is so extreme that the radio emission peak is located clearly downstream of that of the X-rays. This is a rather unanticipated behavior given that the inverse Compton nature of the X-rays and the synchrotron radio emission are attributed to roughly the same electrons of the jet's non-thermal electron distribution. In this note we show that this morphological behavior can result from the gradual deceleration of a relativistic flow and that the offsets in peak emission at different wavelengths carry the imprint of this deceleration. This notion is consistent with another recent finding, namely that the jets feeding the terminal hot spots of powerful radio galaxies and quasars are still relativistic with Lorentz factors $Γ\sim 2-3$. The picture of the kinematics of powerful jets emerging from these considerations is that they remain relativistic as they gradually decelerate from Kpc scales to the hot spots, where, in a final collision with the intergalactic medium, they slow-down rapidly to the subrelativistic velocities of the hot spot advance speed.

description: This paper contains an asymptotic analysis of a fluid model for a heavily loaded processor sharing queue. Specifically, we consider the behavior of solutions of critical fluid models as time approaches \infty. The main theorems of the paper provide sufficient conditions for a fluid model solution to converge to an invariant state and, under slightly more restrictive assumptions, provide a rate of convergence. These results are used in a related work by Gromoll for establishing a heavy traffic diffusion approximation for a processor sharing queue.

description: The evidence of strong coupling between plasmons and molecular excitons for plasmonic nanoparticle (NP) dimers exhibiting ultra-sensitive surface enhanced resonant Raman scattering is the observation of anti-crossing in the coupled resonance. However, it is not easy to experimentally tune plasmon resonance of such dimers for the observation. In this work, we theoretically investigate the anti-crossing properties of the dimers coated by the thin dye films with thicknesses greater than 0.1 nm and gap distances larger than 1.2 nm according to the principles of classical electromagnetism. The plasmon resonance spectra of these dimers are strongly affected by their coupling with the exciton resonance of dye molecules. A comparison of the film thickness dependences of dimer spectral changes with those of silver ellipsoidal NPs indicates that the dipole plasmons localized in the dimer gap are coupled with molecular excitons of the film much stronger than the dipole plasmons of ellipsoidal NPs. Furthermore, the anti-crossing of coupled resonances is investigated while tuning plasmon resonance by changing the morphology and refractive index of the surrounding medium. The spectral changes observed for ellipsoidal NPs clearly exhibit anti-crossing properties; however, the anti-crossing behavior of dimers is more complex due to the strong coupling of dipoles and higher order plasmons with multiple molecular excitons. We find that the anti-crossing for dimers is clearly confirmed by the refractive index dependence of coupled resonance.

description: Cabo Verde é um país desprovido de recursos naturais e com uma geografia física e climática que não propicia em toda a sua extensão a actividade agrícola.
Contudo, e de acordo com o Recenseamento Geral da Agricultura de 2004, 42% dos habitantes correspondiam a população agrícola (INE, 2015). Apesar dos significativos avanços alcançados desde a sua independência em 1975, a pobreza acompanha o processo de desenvolvimento do país. Em 2007 a percentagem da população pobre, população vivendo abaixo do limiar da pobreza, era de 26,6% enquanto “a profundidade da pobreza foi de 8,1%, sendo que no meio urbano este valor foi de 3,3% e no meio rural de 14,3%” (INE, 2015: 63). Deste modo, a atenção que devem merecer quaisquer melhoramentos no sector agrícola e rural são óbvios.
A actividade agrícola constitui atualmente a base económica da Ilha do Fogo, sendo o café uma longa vocação e tradição na produção e exportação, pese embora em valores reduzidos. Muito recentemente, contudo, o cultivo da vinha passou a assumir-se como mais uma alternativa comercial através da produção de vinho. Esta produção, embora remonte ao tempo da colonização, nunca passou de um fabrico artesanal e sem qualidade. Numa tentativa de apoiar a diversificação da produção agrícola e melhorar o nível de rendimentos obtidos pelos produtores rurais, o governo lançou em 2008 o Plano de Acção para o Desenvolvimento da Agricultura na Ilha do Fogo (PADA-Fogo - 2009 a 2012) com o intuito de lançar e implementar o projeto de reabilitação do setor vitivinícola da Ilha do Fogo e nomeadamente nas zonas da Chã das Caldeiras e da Achada Grande, Corvo e Relva.
Assente na caracterização da atividade vitivinícola das famílias rurais caboverdianas da Ilha do Fogo, o objetivo principal deste artigo é dar a conhecer os resultados alcançados por um trabalho de campo nas adegas nos concelhos de Santa Catarina do Fogo e Mosteiros e nos campos de cultivo de vinha e que decorreu em 20104. A amostra correspondeu a produtores de vinha e sócios de duas cooperativas vitivinícolas – a Agro-Coop (Chã) e a Sodade – criadas, respectivamente, em 1998 e 2007. O propósito do inquérito visou, para além da caracterização do perfil sociodemográfico dos produtores de vinha, tentar perceber até que ponto esta produção, seja por aumento da superfície utilizada ou por substituição de outros produtos agrícolas
tradicionais, se traduziu em aumentos de rendimento dos agregados familiares e, correspondentemente, num aumento no seu bem-estar.
Toward creating isotropic microwave composites with negative refraction

description: The properties of artificial isotropic microwave composites which would possess simultaneously negative permittivity and permeability are studied theoretically. Four kinds of composites are considered. Two of them concern media with split-ring resonator particles with different particle arrangements. The other two are realized with Omega particles. An analytical antenna model of the electromagnetic behavior of a split-ring resonator (SRR) is suggested and verified by numerical simulations. Next, material parameters of composite media made with SRR or Omega particles are calculated. It is shown that the Omega-composites are more prospective for obtaining negative real values of permittivity and permeability than the split-ring resonators.

description: We present a new semi-analytic model of the formation of the first stars. Our method takes dark matter halo merger trees (including 3-dimensional spatial information) from cosmological N-body simulations as input and applies analytic prescriptions to compute both the Population III (Pop III) and metal-enriched star formation histories. We have developed a novel method to accurately compute the major feedback processes affecting Pop III star formation: H$_2$ photodissociation from Lyman-Werner (LW) radiation, suppression of star formation due to inhomogeneous reionization, and metal enrichment via supernovae winds. Our method utilizes a grid-based approach relying on fast Fourier transforms (FFTs) to rapidly track the LW intensity, ionization fraction, and metallicity in 3-dimensions throughout the simulation box. We present simulations for a wide range of astrophysical model parameters from $z\approx 30-6$. Initially long-range LW feedback and local metal enrichment and reionization feedback dominate. However, for $z \lesssim 15$ we find that the star formation rate density (SFRD) of Pop III stars is impacted by the combination of external metal enrichment (metals from one halo polluting other pristine halos) and inhomogeneous reionization. We find that the interplay of these processes is particularly important for the Pop III SFRD at $z \lesssim 10$. Reionization feedback delays star formation long enough for metal bubbles to reach halos that would otherwise form Pop III stars. Including these effects can lead to more than an order of magnitude decrease in the Pop III SFRD at $z=6$ compared to LW feedback alone.

description: We theoretically study the low energy electromagnetic response of BCS type superconductors focusing on propagating collective modes that are observable with THz near field optics. The interesting frequency and momentum range is $ω< 2Δ$ and $q < 1/ξ$ where $Δ$ is the gap and $ξ$ is the coherence length. We show that it is possible to observe the superfluid plasmons, amplitude (Higgs) modes, Bardasis-Schrieffer modes and Carlson-Goldman modes using THz near field technique, although none of these modes couple linearly to far field radiation. Coupling of THz near field radiation to the amplitude mode requires particle-hole symmetry breaking while coupling to the Bardasis-Schrieffer mode does not and is typically stronger. For parameters appropriate to layered superconductors of current interest, the Carlson-Goldman mode appears in the near field reflection coefficient as a weak feature in the sub-THz frequency range. In a system of two superconducting layers with nanometer scale separation, an acoustic phase mode appears as the antisymmetric density fluctuation mode of the system. This mode produces well defined resonance peaks in the near-field THz response and has strong anticrossings with the Bardasis-Schrieffer and amplitude modes, enhancing their response. In a slab consisting of many layers of quasi-two dimensional superconductors, realized for example in samples of high T$_c$ cuprate compounds, many branches of propagating Josephson plasmon modes are found to couple to the THz near field radiation.

description: A mathematical model and algorithm which takes into account the effect of ventilation on the spatial pattern of the gas mixture flow in the premises of industrial and domestic purposes are developed. As part of the overall approach a computational technology is proposed that sets additional boundary conditions on the surfaces of the room, adjacent to the ventilation openings, and further iterative solution of the Riemann problem for a given ventilation flow. The proposed approach is tested during the simulation of flow of hydrogen-air gas mixture in the technology box equipped with a ventilation system. To control the fire safety level of the facilities the total mass of fuel gas in the flammable range is used.
