description: We investigate theoretically spin and orbital pseudospin magnetic properties of a molecular orbital in parabolic and elliptic double quantum dots (DQDs). In our many body calculation we include intra- and inter-dot electron-electron interactions, in addition to the intradot exchange interaction of `p' orbitals. We find for parabolic DQDs that, except for the half or completely filled molecular orbital, spins in different dots are ferromagnetically coupled while orbital pseudospins are antiferromagnetically coupled. For elliptic DQDs spins and pseudospins are either ferromagnetically or antiferromagnetically coupled, depending on the number of electrons in the molecular orbital. We have determined orbital pseudospin quantum numbers for the groundstates of elliptic DQDs. An experiment is suggested to test the interplay between orbital pseudospin and spin magnetism.

description: We present a broadband spectral-timing analysis of SMC X-1 at different intensity states of its super-orbital variation using 10 Suzaku and 6 NuSTAR observations. The spectrum in all the states can be described by an absorbed powerlaw with a high energy cutoff and a black-body component along with an iron emission line. Compared to other supergiant HMXBs, the Fe K$α$ line equivalent width is low in SMC X-1 - from less than 10 eV in high state to up to $\sim$ 270 eV in the low states. The spectral shape is dependent on flux with the hard X-ray spectrum steepening with increasing flux. We also report a highly variable normalisation of the power-law component across these 16 super-orbital states. Pulsations in the hard X-rays for both the instruments were detected in all but two observations. The pulse profiles are near sinusoidal with two peaks and the relative intensity of the second peak decreasing with decreasing luminosity. These findings suggest that the super-orbital modulation in SMC X-1 is not caused by absorption in precessing warped accretion disc alone and there are intrinsic changes in X-rays emanating from the neutron star at different super-orbital states. We also note a putative cyclotron line at $\sim$ 50 keV in the \nustar~spectra of three bright states indicating a possible magnetic field of $\sim$ 4.2 $\times$ 10$^{12}$ G. Finally, with the new pulse period measurements reported here, the time base for the secular spin-up of SMC X-1 is increased by thirteen years and the complete pulse period history shows a sudden change in the spin-up trend around 1995.

description: As part of the 2020 Vision initiative, IFPRI has identified key issues for which better knowledge is required if poverty and hunger in developing countries are to be alleviated by 2020. IFPRI is addressing the issues of rural poverty and unemployment from many different directions, including research on policies to encourage rural development, rural credit and saving programs, safety nets for those left behind by economic growth, and the role of government policy when emphasis is on market-led development. One of the most urgent issues to be addressed is the future direction of the nonfarm rural sector in the context of overall rural development. In most developing countries, the rural labor force is growing rapidly, but employment opportunities are dwindling. As land available for expansion of agriculture becomes an increasingly scare, opportunity for nonfarm employment must expand if deepening rural poverty is to be avoided. Given the expected growth and composition of large-scale urban industries, they are unlikely to be able to absorb the rising tide of workers migrating from the countryside to the cities. Looking toward 2020, we must slow the process of urban spread, with its high social and environmental costs such as congestion, pollution, and skyrocketing land costs. Expansion of the rural nonfarm sector, with its emphasis on labor-intensive and small-scale enterprises, widens income opportunities for the poor, including small farmers, the landless, and women, enabling them to even out extreme fluctuations in their incomes. This paper brings together much-needed empirical evidence on the nonfarm sector and provides a systematic analysis of policies for its future development that may be needed individual developing countries and regions. It reviews what is now occurring in activities ranging from rural trade and service to cottage industries to small-scale industries. It provides insights on the linkages between the nonfarm and the farm sectors, and between the nonfarm sector and urban enterprises, and considers ways the government can assist in promoting the sector through education, training, credit, infrastructure, and local government programs. We at IFPRI hope that the paper will stimulate further research and analysis and help policymakers in identifying critical issues for public action in this important area.

description: We use magnetoconductance fluctuation measurements of phase-coherent semiconductor billiards to quantify the contributions to the nonlinear electric conductance that are asymmetric under reversal of magnetic field. We experimentally determine that the average asymmetric contribution is linear in magnetic field (for magnetic flux much larger than one flux quantum) and that its magnitude depends on billiard geometry. In addition, we find an unexpected asymmetry in the power spectrum characteristics of the magnetoconductance with respect to reversal of magnetic field and bias voltage.

description: Rating agencies' track record is good in developed countries but poor in emerging economies. Why? Given the almost-monopolistic structure of the industry, we conjecture that agencies might underinvest in information gathering. We propose an indicator quantifying the agencies' effort to gather information and assess whether greater effort affects rating levels. We detect: (i) absolute underinvestment for non-OECD sovereigns (less effort in spite of greater opaqueness); (ii) relative underinvestment for non-OECD firms compared with OECD ones (though the former receive a larger effort, more intense effort boosts firm ratings in non-OECD countries while depressing them in OECD countries).

description: Eutrophication has been commonly acknowledged as a typical problem of the Baltic Sea, but it is also emerging in Finnish inland waters. As municipal sources of nutrients have been addressed by enhancing waste water treatment, the pressure has focused to agriculture along with the adoption of the EU- Water Framework Directive, which aims to improve surface water quality to “good ecological status” by 2015. The implementation of the directive will likely affect water recreation behavior and benefits. In this study we modeled water recreation participation and water quality econometrically using a hurdle model for three activities: swimming, fishing and boating. In addition, we estimated the consumer surplus for a water recreation day using a travel cost approach. We found that close-to-home water quality affects swimming and fishing behavior positively, and that for a 1-meter improvement in water clarity, consumer surplus for swimmers would increase at a range between 32 to 97 million Euros, and for fishers by 43 to 130 million Euros. In comparison with previously estimated costs of decreasing agricultural nutrient flow to the Gulf of Finland, we found that net benefits may be positive.

description: Magnetic flux ropes (MFRs) are usually considered to be the magnetic structure that dominates the transport of helicity from the Sun into the heliosphere. They entrain a confined plasma within a helically organized magnetic structure and are able to cause geomagnetic activity. The formation, evolution and twist distribution of MFRs are issues subject to strong debate. Although different twist profiles have been suggested so far, none of them has been thoroughly explored yet. The aim of this work is to present a theoretical study of the conditions under which MFRs with different twist profiles are kink stable and thereby shed some light on the aforementioned aspects. The magnetic field is modeled according to the circular-cylindrical analytical flux rope model in Nieves-Chinchilla et al. (Astrophys. J. 823, 27, 2016) as well as the Lundquist and Gold-Hoyle models, and the kink stability is analyzed with a numerical method that has been developed based on Linton, Longcope, and Fisher (Astrophys. J. 469, 954, 1996). The results are discussed in relation to MFR rotations, magnetic forces, the reversed chirality scenario, and the expansion throughout the heliosphere, among others, providing a theoretical background to improve the current understanding of the internal magnetic configuration of coronal mass ejections (CMEs). The data obtained by new missions like Parker Solar Probe or Solar Orbiter will give the opportunity to explore these results and ideas by observing MFRs closer than ever to the Sun.

description: Silicon's weak intrinsic spin-orbit coupling and centrosymmetric crystal structure are a critical bottleneck to the development of Si spintronics, because they lead to an insignificant spin-Hall effect (spin current generation) and inverse spin-Hall effect (spin current detection). Here, we undertake current, magnetic field, crystallography dependent magnetoresistance and magneto thermal transport measurements to study the spin transport behavior in freestanding Si thin films. We observe a large spin-Hall magnetoresistance in both p-Si and n-Si at room temperature and it is an order of magnitude larger than that of Pt. One explanation of the unexpectedly large and efficient spin-Hall effect is spin-phonon coupling instead of spin-orbit coupling. The macroscopic origin of the spin-phonon coupling can be large strain gradients that can exist in the freestanding Si films. This discovery in a light, earth abundant and centrosymmetric material opens a new path of strain engineering to achieve spin dependent properties in technologically highly-developed materials.

description: The research based on primary data examines the answers given by Hungarian farms to the challenges of the changing economic environment following the accession to the European Union. The experience shows that the Hungarian farms have given basically false answers to the changing economic relation system. The subsidies have emerged on the market as "visible hands" and by allowing their impact which distorted the economic rationality, the basic economic aspects of production have been ignored. In the near future it will be especially important to liquidate this abnormal situation. This step will definitely indicate the demand to separate the social and producing agriculture, providing ground for the spreading of farmers’ cooperation.

description: Ultra-low frequency observations (<100 MHz) are particularly challenging because they are usually performed in a low signal-to-noise ratio regime due to the high sky temperature and because of ionospheric disturbances whose effects are inversely proportional to the observing frequency. Nonetheless, these observations are crucial to study the emission from low-energy populations of cosmic rays. We aim to obtain the first thermal-noise limited (~ 1.5 mJy/beam) deep continuum radio map using the LOFAR Low Band Antenna (LBA) system. Our demonstration observation targeted the galaxy cluster RX J0603.3+4214 (the "Toothbrush" cluster). We used the resulting ultra-low frequency (58 MHz) image to study cosmic-ray acceleration and evolution in the post shock region, as well as their relation with the presence of a radio halo. We describe the data reduction we have used to calibrate LOFAR LBA observations. The resulting image is combined with observations at higher frequencies (LOFAR 150 MHz and VLA 1500 MHz) to extract spectral information. We obtained the first thermal-noise limited image from an observation carried out with the LOFAR LBA system using all Dutch stations at a central frequency of 58 MHz. With 8 hours of data, we reached an rms noise of 1.3 mJy/beam at a resolution of 18" x 11". The procedure we have developed is an important step forward towards routine high-fidelity imaging with the LOFAR LBA. The analysis of the radio spectra shows that the radio relic extends to distances of 800 kpc downstream from the shock front, larger than what allowed by electron cooling time. Furthermore, the shock wave started accelerating electrons already at a projected distance of <300 kpc from the crossing point of the two clusters. These results can be explained if electrons are reaccelerated downstream by background turbulence possibly combined with projection effects.

description: The purpose of this paper is to test the main hypotheses of the recent theoretical literature on the political economy of reform for the case of the Latin American countries between 1985 and 1995. The paper first reviews the literature and extracts the main testable hypotheses. Then, a system of indices that measure the extent of reform in five policy areas is presented. These indices are used as the dependent variables in panel regressions where the main explanatory variables are indicators of crisis, political variables and indicators of channels of contagion. We find very strong support for the well-known hypothesis that crises make reform viable and also for the (less theoretically sound) hypotheses that reforms are more likely at the beginning of government periods. None of the hypotheses on the role of political and distributional variables, the importance of compensation schemes or contagion, finds support in our results. Rather disappointingly, however, most of the reforms seem to have responded to a process of convergence.

description: In the last decades the Common Agricultural Policy has evolved towards a less intensive approach based in a multifunctional agriculture respectful with the environment. At the same time, following the enacting of the Water Framework Directive in 2000, water policies and management regimes are also evolving towards more integrated water management with an active stakeholders’ involvement. In this context, the aim of this paper is to analyze the impact of water conservation policies and agricultural policies (Cross-Compliance: Nitrates Directive) in the Upper Guadiana River basin (Spain), where intensive irrigated agriculture resulted in the overexploitation of the Western La Mancha aquifer and the subsequent degradation of the highly valuable wetlands, and in an important nitrates’ pollution. Focus is made on farmers’ vulnerability to these policies and the synergies between them. The methodology combines qualitative and quantitative aspects defined by the integration of an economic and an agronomic model (CropSyst), and a vulnerability analysis. The economic model (mathematical programming model) simulates farmers’ behaviour facing different policy options. The results of the economic model are used as an input for the analysis of farms’ vulnerability based on farm income indicators, through the elaboration of a vulnerable farms classification tree using CART (Classification and Regression Trees). The results of the model show that farm income is more sensitive to water use limitations than to nitrogen restrictions. Farm size and Water Authority’s policy enforcement capacity are key variables in determining farmers’ vulnerability, being small and legal farms the most vulnerable ones.

description: Water management has evolved in the last years towards more integrated and participatory approaches, aiming at improving the adaptability of water systems. Following this line, we propose a methodology to build a decision support system, based on the participation of stakeholders and the integration of the different disciplines involved in water use, as well as the inclusion of uncertainties in the management planning. The process has been implemented in the Upper Guadiana basin (Spain) with the aim of solving the existing conflicts: the aquifer, which is the main water source in the area, has been over-exploited during the last decades for irrigation. This has lead to serious degradation of natural water-related ecosystems and important social conflicts. The river basin authority has tried to implement different policies to attain the aquifer recovery, so far without much success. At present, a new management plan specifically for the Upper Guadiana has been approved, where some policy measures are proposed for attaining the reduction of agricultural water consumption. The methodology proposed in this work is based on the combination of a Bayesian network and an economic mathematical programming model, elaborated with the active participation of stakeholders. The resulting DSS will be used to evaluate different management options, within those included in the Special Plan of the Upper Guadiana, in terms of their impacts on the agricultural income and the environmental sustainability. Results show that new measures would not be successful unless they are accompanied by an increase of compliance of farmers with water regulations.
Antioxident effects of caseinophosphopeptides (CPP) and associated conjugates in chemical models and cell culture systems in vitro
Creators: name: Chiu, Sheila Chin Kiu
Publisher: name: University of British Columbia
Year: 2009

description: Caseinophosphopeptides (CPP) derived from tryptic digests of bovine milk casein were evaluated for potential antioxidant activity. Two different commercially available (Meiji Seika Kaisha Ltd. Japan) CPP fractions, CPP-I and III, were shown to interact with ferrous iron, ferric iron and calcium ions. CPP-I and III exhibited significant (p<0.01) inhibition of both site-specific and non site-specific degradation of deoxyribose in a Fenton reaction oxidation test and protected liposomes from oxidation induced by ferrous iron and free radical AAPH . CPP-I was more effective (p<0.01) at quenching ABTS radicals than CPP-III. Laboratory synthesized CPP and CPP-saccharide conjugates were also analyzed for antioxidant activity. Different preparation techniques yield CPP of different calcium concentrations and peptide sizes. It appears that all CPP peptides carry the required polar, acidic Ser-P-Ser-P-Ser-P-Glu-Glu domain for ideal conformation for metal binding. CPP III was shown to be the most effective (p<0.01) at binding iron and lowering deoxyribose oxidation, while CPP-IJ was more effective (p<0.01) at sequestering ABTS radicals. All of the CPP preparations were equally effective (p>0.05) at quenching peroxyl radicals in the liposome peroxidation model. Conjugation of CPP with polysaccharide galactomannan and oligosaccharide xyloglucan did not enhance the bioactivity of CPP as predicted. Hence, both commercially available and laboratory synthesized CPP can act as a primary and also a secondary antioxidant by displaying both metal sequestering and free radical quenching activity in aqueous and emulsion models. Using a reduced serum culture system, laboratory synthesized CPP-III was also shown to be relatively non-toxic to intestinal cells and to successfully protect human intestinal embryonic Int-407 and colon carcinoma Caco-2 cells from ferrous sulphate-induced cytotoxicity. With a selective affinity to sequester free metal ions, such as iron, and a low toxicity in intestinal cells, bioactive casein derived peptides can act as a potential antioxidant co-nutrient that serves to remove pro-oxidative metal catalysts and free radicals from oxidizable lipids in labile food systems or biomembrane lipid bilayer systems in vivo, especially at the site of the intestine.

We give an interpretation of the spontaneous symmetry breaking of SO(6)-> SO(3)_H x SO(3)_V from the viewpoint of the Riemann surface by following the argument of Minahan. Then we use the concrete form of the resolvent for a single cut solution and compute the anomalous dimension of operators dual to an open pulsating string at three-loop level. In the string side we obtain the energy of the open pulsating string solution by semiclassical analysis. Both results agree at two-loop level but we find a three-loop discrepancy.

Besides, the width of the decay $ϕ\to 3π$ and the cross-section of the process $e^{+}e^{-} \to π^{0} ϕ$ are calculated by using this angle.

description: This paper evaluates the possible consequences of decreasing in the amount of water provided by the irrigation board to the farms, and increasing in the unitary water charges that the irrigation board applies to the farms. The study has been conducted in a Mediterranean region of southern Italy where farmers can use water delivered by an irrigation board and by privately owned wells. The results of the analysis, performed by means of a mathematical programming model, show that in both cases farmers substitute the water supplied by the irrigation board with that extracted from farm wells. This generates an over-extraction of resources from the aquifer leading to likely negative environmental consequences. This also endangers the economic sustainability of the irrigation boards, which are institutions whose activity can be monitored and influenced by public administration bodies.

description: Twinning is an important mode of plastic deformation in metallic nanopillars. When twinning occurs on multiple systems, it is possible that twins belonging to different twin systems interact and forms a complex twin-twin junctions. Revealing the atomistic mechanisms of how twin-twin interactions lead to different twin junctions is crucial for our understanding of mechanical behaviour of materials. In this paper, we report the atomistic mechanisms responsible for the formation of two different twin-twin interactions/junctions in Cu nanopillars using atomistic simulations. One junction contains two twin boundaries along with one $Σ$9 boundary, while the other contains five twin boundaries (five-fold twin). These junctions were observed during the tensile deformation of [100] and $[1\bar1 0]$ Cu nanopillars, respectively.

Top Quark Mass Measurement Using the Template Method in the Lepton + Jets Channel at CDF II
Creators: name: CDF Collaboration
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: This article presents a measurement of the top quark mass using the CDF II detector at Fermilab. Colliding beams of protons and anti-protons at Fermilab's Tevatron (sqrt{s}=1.96 TeV) produce top/anti-top pairs, which decay to W^+W^-bbbar; events are selected where one W decays to hadrons, and one W decays to either e or mu plus a neutrino. The data sample corresponds to an integrated luminosity of approximately 318 pb^-1. A total of 165 ttbar events are separated into four subsamples based on jet transverse energy thresholds and the number of b jets identified by reconstructing a displaced vertex. In each event, the reconstructed top quark invariant mass is determined by minimizing a chi-squared for the overconstrained kinematic system. At the same time, the mass of the hadronically decaying W boson is measured in the same event sample. The observed W boson mass provides an in situ improvement in the determination of the hadronic jet energy scale, JES. A simultaneous likelihood fit of the reconstructed top quark masses and the W boson invariant masses in the data sample to distributions from simulated signal and background events gives a top quark mass of 173.5 +3.7/-3.6 (stat.+JES) +/- 1.3 (other syst.) GeV/c^2, or 173.5 +3.9/-3.8 GeV/c^2.

description: We study neutron matter by combining pionless effective field theory with non-perturbative lattice methods. The neutron contact interaction is determined by zero temperature scattering data. We simulate neutron matter on the lattice at temperatures 4 and 8 MeV and densities below one-fifth normal nuclear matter density. Our results at different lattice spacings agree with one another and match bubble chain calculations at low densities. The equation of state of pure neutron matter obtained from our simulations agrees quantitatively with variational calculations based on realistic potentials.

description: Non-locality of the type first elucidated by Bell in 1964 is a difficult concept to explain to non-specialists and undergraduates. Here we attempt this by showing how such non-locality can be used to solve a problem in which someone might find themselves as the result of a collection of normal, even if somewhat unlikely, events. Our story is told in the style of a Sherlock Holmes mystery, and is based on Mermin's formulation of the "paradoxical" illustration of quantum non-locality discovered by Greenberger, Horne and Zeilinger.

description: This paper reviews the application of a scenario for the 2015 agricultural policy and markets for the irrigated agriculture in Europe. Scenarios for irrigated agriculture 2015 are described in detail including Reformed CAP and how biofuel impacts demand. A model for irrigation water demand is applied at the basin level for the Guadalquivir River (Southern Spain). The methodology is based upon residual value of water and it combines budget and farm analysis at municipality level, with the Guadalquivir basin divided at 50 counties where 24 possible crops are selected and adapted specifically to each county yield and costs. The result is a comparative analysis between actual level of water use and value, and 2015 scenario at county level and later aggregated at basin level.
