K → π matrix elements of the chromomagnetic operator on the lattice

We present the results of the first lattice QCD calculation of the K -> pi matrix elements of the chromomagnetic operator O-CM = g (s) over bar sigma(mu nu)G(mu nu)d, which appears in the effective Hamiltonian describing Delta S = 1 transitions in and beyond the standard model. Having dimension five, the chromomagnetic operator is characterized by a rich pattern of mixing with operators of equal and lower dimensionality. The multiplicative renormalization factor as well as the mixing coefficients with the operators of equal dimension have been computed at one loop in perturbation theory. The power divergent coefficients controlling the mixing with operators of lower dimension have been determined nonperturbatively, by imposing suitable subtraction conditions. The numerical simulations have been carried out using the gauge field configurations produced by the European Twisted Mass Collaboration with N-f = 2 + 1 + 1 dynamical quarks at three values of the lattice spacing. Our result for the B parameter of the chromomagnetic operator at the physical pion and kaon point is B-CMO(K pi) = 0.273(69), while in the SU(3) chiral limit we obtain B-CMO = 0.076(23). Our findings are significantly smaller than the model-dependent estimate B-CMO similar to 1-4, currently used in phenomenological analyses, and improve the uncertainty on this important phenomenological quantity.
Five Years of Subsurface Drip Irrigation on Peanut: What Have We Learned?1

Abstract Long term peanut yield with various crop rotations and irrigated with subsurface drip irrigation (SDI) is not known. A subsurface drip irrigation system was installed in 1998 on a Tifton loamy sand (Fine-loamy, kaolinitic, thermic Plinthic Kandiudults) with five crop rotations, two drip tube lateral spacings, and three irrigation levels. Crop rotations ranged from continuous peanut (Arachis hypogaea L.) to four years between peanut rotated with either cotton (Gossypium hirusutum L.) and/or corn (Zea mays L.). Laterals were installed underneath each crop row (narrow) and alternate row middles (wide). Crops were irrigated daily at 100, 75 and 50% of estimated crop water use. Continuous peanut yields averaged 3107 kg ha−1 while peanut in rotation averaged 4031 kg ha−1. Yield of peanut in any rotation and with narrow spaced drip tube laterals averaged 4883 kg ha−1 and wide spaced laterals averaged 4592 kg ha−1. Peanut in any rotation and irrigated at 75% had the same pod yield as the 100% irrigated i.

The purpose of the present study is to evaluate the quality of services provided by the libraries of AJA University of Medical Sciences using the LibQUAL
Downs English-Speaking Preschoolers Attending Head Start Psychometric Properties of the Emotion Understanding Assessment With Spanish-and

The Emotion Understanding Assessment (EUA) is based on a theoretical model of recognizing emotion expressions and reasoning about situation-based, desire-based, and belief-based emotions. While research has noted that emotion understanding predicts current and future social and academic functioning, little is known about the psychometric properties of the EUA. This research sought to test the EUA factor structure and measurement invariance across gender, across language (English and Spanish speakers), and over time (24 weeks) in 281 preschoolers attending Head Start. Results indicated that a two-factor model of emotion expression recognition and emotional perspective taking of the EUA fit the data for the total sample, for each group (gender and language), and at each time point. Furthermore, configural and scalar invariance of the EUA was demonstrated across gender, language, and time. These results offer support that the EUA is assessing emotion expression recognition and emotional perspective taking constructs equivalently in boy, girls, Spanish and English speakers, and over time. Examination of latent means across groups and time indicate no differences in emotion understanding based on gender or language or over the 24-week time frame in this sample of preschoolers attending Head Start.
2 IgG 4-Related Disease ( IgG 4-RD ) and Microbe-Associated Molecular Patterns ( MAMPs ) and Damage-Associated Molecular Patterns ( DAMPs ) 2 . 1 MAMPs and DAMPs

An increased number of clinicopathological studies on autoimmune pancreatitis, cholangitis, and sialoadenitis have led to the recognition of immunoglobulin G4-related disease (IgG4-RD) as a novel disorder, characterized by elevated levels of serum IgG4 and infiltration of IgG4-expressing plasma cells in the affected organs. Although the immunological background associated with the development of IgG4-RD remains poorly understood, recent studies have suggested involvement of the innate immune response in its pathogenesis. Peripheral blood innate immune cells, such as plasmacytoid dendritic cells and monocytes isolated from patients with IgG4-RD, promote IgG4 production by B cells. Activation of the innate immune response by microbeand/or damage-associated molecular patterns stimulates production of type I interferon and B cell-activating factor by innate immune cells and results in IgG4 production by B cells. Elucidation of the innate immune response associated with IgG4-RD may help identify a new therapeutic target for this immune disorder.
Mobile Phone Revolution in Ghana's Cocoa Industry 1

This paper focused on the use of mobile phone by cocoa farmers in the four leading cocoa producing regions in Ghana-Western, Ashanti, Brong Ahafo and Eastern. The study examined the use of mobile phones by cocoa farmers and benefits associated with their usage. The sample of study was 400 cocoa farmers randomly chosen from the study area. The qualitative method was used in collecting data because of the low educational background of respondents. It was found that a high proportion of cocoa farmers (61%) owned mobile phones which had contributed to an improvement in communication in cocoa growing communities and transformed cocoa farmers’ mode of production. The mobile phone was used by cocoa farmers to meet economic and social needs like arranging for inputs, sale of produce, sharing information and keeping in touch with friends and relations. As a result, cocoa farmers have been able to reduce their transport cost. Key word: Mobile phone, economic and social needs, sharing information, transport cost.
Efficacy and safety of novel oral anticoagulants versus vitamin K antagonists in the treatment of venous thromboembolism

The aim of this meta-analysis was to systematically evaluate the efficacy and safety of novel oral anticoagulants and vitamin K antagonists in the treatment of venous thromboembolism. A total of 6 studies met the inclusion criteria and a total of 19,350 patients with venous thromboembolism were included. Among them, rivaroxaban (3 RCTs, n=90/3,449/4,832); dabigatran (2 RCTs, n=200/2,539); edoxaban (1 RCT, n=8,240). The results of meta-analysis showed that the total bleeding rate after treatment with the vitamin K antagonist group was higher than with the new oral anticoagulant group (OR=0.82, 95% confidence interval 0.75-0.90, p<0.0001), and the difference was highly statistically significant. Overall, new oral anticoagulants are compara-ble to vitamin K antagonists, but new oral anticoagulants can reduce the occurrence of bleeding events and the safety was superior to vitamin K antagonists.
Solving Optimal Dividend Problems via Phase-Type Fitting Approximation of Scale Functions

The optimal dividend problem by De Finetti (1957) has been recently generalized to the spectrally negative Levy model where the implementation of optimal strategies draws upon the computation of scale functions and their derivatives. This paper proposes a phase-type fitting approximation of the optimal strategy. We consider spectrally negative Levy processes with phase-type jumps as well as meromorphic Levy processes (Kuznetsov et al., 2010a), and use their scale functions to approximate the scale function for a general spectrally negative Levy process. We obtain analytically the convergence results and illustrate numerically the effectiveness of the approximation methods using examples with the spectrally negative Levy process with i.i. d. Weibull-distributed jumps, the β-family and CGMY process.
SUB-SYNCHRONOUS OSCILLATION MONITORING IN POWER SYSTEM By HAMED KHALILI NIA A dissertation submitted in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY

by Hamed Khalili Nia, Ph.D. Washington State University August 2015 Chair: Mani V. Venkatasubramanian In this thesis, online monitoring of the Sub-Synchronous Oscillation (SSO) using ringdown and also ambient data has been studied. IEEE second benchmark model for Sub-Synchronous Resonance (SSR) is used as the case study system. Nonlinear and linearized equations of this system have been extracted to test the performance of the measurement based methods and to compare the results with the real modes of the system. Also, in addition to frequency and damping ratio, torsional mode shapes can be identified by implementing the identification methods on the ambient data. The accuracy of the results shows the possibility of the mechanical parameters online identification using ambient data. Several ringdown algorithms, namely, Prony, Matrix Pencil, HTLS and ERA methods have been tested for ringdown analysis of SSR related modes. The observability of the sub-synchronous oscillation modes from mechanical and also electrical signals has been examined and it is shown that both electrical and mechanical signals can be used for the SSR monitoring purpose while these modes are more observable in the mechanical signals. Using mechanical signals, such as generator speed or difference between speeds of two turbine shaft masses, shorter analysis window can be used for SSR monitoring which helps earlier SSR detection. It is shown that the analysis can provide early alarm or generator trip signal in about 350 milliseconds.
Priming and drying on the physiological quality of eggplant seeds

We evaluated the effect of the priming with polyethyleneglicol (PEG) 6000 followed or not of drying on two lots of eggplant seeds with medium and low vigor respectively. The seeds were submitted to the treatments of priming with PEG 6000 in the osmotic potentials of -0.6, -0.9 and -1.2 MPa during 48 or 96 hours of priming with and without subsequent drying. For the soaking of seeds in osmotic solutions, these were placed over three sheets of paper boxes such germitest gerbox conditioning moistened with each solution in a 3:1 ratio. The control group was represented by unprimed seeds. The priming for both lots provided higher values in relation to the vigor through the first counting of germination, seedlings and primary root length, germination and emergence rates, emergence and dry weight of seedlings when compared to the non-primed seeds. These results were not verified for germination; significant differences practically were not observed in relation to the controls. Improvements in relation to the vigour were not higher on lot 2 than those obtained on lot 1. The priming with PEG 6000 with subsequent drying increased the vigor of eggplant seeds of the cultivar Morro Grande in relation to those non-primed, however, without differences in the germination.
Development of a Short Form Psychometric Properties of the Five Facet Mindfulness Questionnaire in Depressed Adults and-Aug

In recent years, there has been a growing interest in therapies that include the learning of mindfulness skills. The 39-item Five Facet Mindfulness Questionnaire (FFMQ) has been developed as a reliable and valid comprehensive instrument for assessing different aspects of mindfulness in community and student samples. In this study, the psychometric properties of the Dutch FFMQ were assessed in a sample of 376 adults with clinically relevant symptoms of depression and anxiety. Construct validity was examined with confirmatory factor analyses and by relating the FFMQ to measures of psychological symptoms, well-being, experiential avoidance, and the personality factors neuroticism and openness to experience. In addition, a 24-item short form of the FFMQ (FFMQ-SF) was developed and assessed in the same sample and cross-validated in an independent sample of patients with fibromyalgia. Confirmatory factor analyses showed acceptable model fit for a correlated five-factor structure of the FFMQ and good model fit for the structure of the FFMQ-SF. The replicability of the five-factor structure of the FFMQ-SF was confirmed in the fibromyalgia sample. Both instruments proved highly sensitive to change. It is concluded that both the FFMQ and the FFMQ-SF are reliable and valid instruments for use in adults with clinically relevant symptoms of depression and anxiety.
Detection of Peripheral Ventilation Inhomogeneity in Smokers

BACKGROUND: In smokers, ‘small airways’ narrowing alters the conventional, vital capacity single breath washout (SBWVC). Although, in some studies, the test predicts smokers at risk of developing chronic airflow limitation, its wide variability partly explains its poor positive predictive value. An alternative explanation for the test’s poor predictive value is that it may not accurately reflect small airway narrowing in the lung periphery.
Characterization of PM 10 sources in the central Mediterranean

Abstract. The Mediterranean Basin atmosphere is influenced by both strong natural and anthropogenic aerosol emissions and is also subject to important climatic forcings. Several programs have addressed the study of the Mediterranean basin; nevertheless important pieces of information are still missing. In this framework, PM10 samples were collected on a daily basis on the island of Lampedusa (35.5° N, 12.6° E; 45 m a.s.l.), which is far from continental pollution sources (the nearest coast, in Tunisia, is more than 100 km away). After mass gravimetric measurements, different portions of the samples were analyzed to determine the ionic content by ion chromatography (IC), the soluble metals by inductively coupled plasma atomic emission spectrometry (ICP-AES), and the total (soluble + insoluble) elemental composition by particle-induced x-ray emission (PIXE). Data from 2007 and 2008 are used in this study. The Positive Matrix Factorization (PMF) model was applied to the 2-year long data set of PM10 mass concentration and chemical composition to assess the aerosol sources affecting the central Mediterranean basin. Seven sources were resolved: sea salt, mineral dust, biogenic emissions, primary particulate ship emissions, secondary sulfate, secondary nitrate, and combustion emissions. Source contributions to the total PM10 mass were estimated to be about 40 % for sea salt, around 25 % for mineral dust, 10 % each for secondary nitrate and secondary sulfate, and 5 % each for primary particulate ship emissions, biogenic emissions, and combustion emissions. Large variations in absolute and relative contributions are found and appear to depend on the season and on transport episodes. In addition, the secondary sulfate due to ship emissions was estimated and found to contribute by about one-third to the total sulfate mass. Results for the sea-salt and mineral dust sources were compared with estimates of the same contributions obtained from independent approaches, leading to an estimate of the water content bound to the sea salt in the marine source.
20. THE PETROGRAPHY, MINERAL CHEMISTRY, AND ONE-ATMOSPHERE PHASE RELATIONS OF BASALTS FROM SITE 395

Two distinct textural-chemical types of basalt are present in Holes 395 and 395A. Aphyric basalts are of two types: those with only olivine on the liquidus and those multiply saturated with Plagioclase and olivine. Porphyritic basalts contain phenocrysts of Plagioclase, olivine, spinel, and clinopyroxene. There is a discrepancy between the compositions of phenocryst phases in the rocks and olivine and Plagioclase produced in one-atmosphere melting experiments. The disequilibrium mineralogy is suggestive of the mixing of primitive and evolved magmas, before eruption, in shallow magma chambers.
AFRL-RX-WP-TP-2009-4356 A MODEL FOR THE OXIDATION OF ZrB 2 , HfB 2 AND TiB 2 ( POSTPRINT )

A mechanistic model that interprets the oxidation behavior of the diborides of Zr, Hf and Ti in the temperature range of 1000– 1800 C was formulated. Available thermodynamic data and literature data for vapor pressures and diffusivities were used to evaluate the model. Good correspondence was obtained between theory and experiments for weight gain, recession and scale thickness as functions of temperature and oxygen partial pressure. At temperatures below about 1400 C, the rate-limiting step is the diffusion of dissolved oxygen through a film of liquid boria in capillaries at the base of the oxidation product. At higher temperatures, the boria is lost by evaporation, and the oxidation rate is limited by Knudsen diffusion of molecular oxygen through the capillaries between nearly columnar blocks of the oxide, MO2. 2007 Acta Materialia Inc.

Resistivity, thermopower and the correlation to infrared active vibrations of Mn1.56Co0.96Ni0.48O4 spinel films sputtered in an oxygen partial pressure series

Mn1.56Co0. 96Ni0.48O4 spinel was sputter deposited using a series of oxygen partial pressures. Electrical resistivity versus temperature and thermopower versus temperature measurements at each oxygen partial pressure were made. The variations of the thermopower and resistivity with oxygen partial pressure are consistent with a change in the ratio of Mn3+to Mn4+ cations, which occurs due to changes of oxygen content of the material. The weak temperature dependence of the thermopower indicates small polaron hopping is the charge transport mechanism. Combining the models of Mott and Schnakenberg to analyze the transport data, we find that the Debye temperature (or frequency) is an increasing function of the oxygen partial pressure used during sputtering. The calculated shift in the Debye frequency from the resistivity is consistent with the observed shift in the fundamental infrared active lattice vibrations from Fourier transform infrared spectroscopy and Raman spectroscopy.
Fiber orientation effects on high strain rate of Ca rbon / epoxy composites

Specific mechanical properties of composites make t hem particularly attractive. Dynamic loads are of prime interest for their applications. Laminated st ructures’ impact modelling implies prior material dynamic characterisation. This study suggests an an lysis of split Hopkinson bar compression testing o T300/914 carbon/epoxy composite material. First, the effect of fibre orientation and stratifi cation on compression dynamic behaviour is studied. Results show a high non-linearity for +/-45° lamin ates testing. This non-linearity is not observed wh en the laminates are reinforced with 0° and 90° plies. Analytical modelling is in agreement with the experimental results. Secondly, experiments are per formed on pre-cracked specimens to show the influence of cracking on dynamic behaviour.
FMR1 Repeats and Ovarian Reserve: CGG Repeat Number does not Influence Antral Follicle Count

Background: Premature ovarian failure has been reported in women carrying FMR1 premutations. This study explored the association between number of FMR1 CGG repeats and Antral Follicle Count (AFC) in infertile women. Methods: Retrospective cross-sectional study; 350 infertile women underwent FMR1 genotyping and ultrasound for AFC at an academic reproductive medical center. Women with premature ovarian failure were excluded. FMR1 repeats were classified as Result(s): Only 1 woman carried a premutation, with 57 CGG repeats. Seven women carried intermediate alleles (<2%). FMR1 repeat number was not a significant predictor of AFC in an age-adjusted linear regression when the highest number allele or both allele members were included. Age-adjusted AFC did not differ between FMR1 groups by any of the classification systems used. Conclusion(s): FMR1 intermediate alleles and premutations are rare in infertile women in the San Francisco Bay Area, with prevalence comparable to the general population. FMR repeat number does not correlate with AFC in this ethnically diverse population.
The Cellular Fatty Acids of the Sulphate-reducing Bacteria, Desulfobacter sp., Desulfobulbus sp. and Desulfovibrio desulfuricans

Summary: The fatty acid profiles of Desulfobacter sp. grown on acetate and Desulfobulbus sp. grown on propionate, lactate and H2/CO2 were analysed. Desulfobacter sp. grown on acetate and Desulfobulbus sp. grown on H2/CO2 gave mainly even numbered straight chain acids but odd numbered acids predominated in Desulfobulbus sp. grown on propionate, reflecting the use of the growth substrates provided as chain initiators for fatty acid biosynthesis. The cellular fatty acids of Desulfobulbus sp. grown on lactate were distributed approximately evenly between even and odd straight chain acids. In contrast those of Desulfovibrio desulfuricans, were dominated by branched chain iso and anteiso fatty acids, when grown on either lactate or H2/CO2. On the basis of the fatty acid biosynthetic pathways these sulphate-reducing bacteria could be separated into two groups, one comprising Desulfobacter sp. and Desulfobulbus sp. and the other more primitive Desulfovibrio desulfuricans.
PHOTOSYNTHETIC PRODUCTIVITY OF PEAR TREES GROWN ON DIFFERENT ROOTSTOCKS

Since the pear is not a flagship crop in Polish orchards, very little advanced research is conducted to obtain knowledge about its photosynthetic productivity strategies. The research described in this paper involves measurements of the physiological state and yield of pear trees (cv. ‘Conference’) budded on different rootstocks. The main aim is to monitor the influence of budding on different rootstocks on photosynthetic productivity, growth, and yield of this cultivar, in order to improve agricultural practices for a sustainable horticulture. Leaf gas exchange, photosynthetic efficiency, leaf area index, and chlorophyll content were measured, as was tree yield. Our results provide better understanding of the physiological factors behind pear productivity.
