description: In Kenya, over 80 percent of smallholder farmers are engaged in the cultivation of horticultural crops. Passion fruit is one of the high value horticultural crops produced by smallholder farmers because of high returns. The enterprise is gaining inroads in the predominantly cereal growing areas of North Rift. Its production has not been intensified since farmers grow few vines, but they are now forming passion fruit producer and marketing groups. However, the contribution of collective action in production and marketing of passion fruits is not clear, and this formed the basis of the study. The study was conducted in Nandi County with the following objectives: to determine the factors that influence participation and commitment in producer and marketing groups; to determine the effect of collective action on enterprise performance, and to establish the effect of household, technical and institutional factors on the choice of the marketing channel among smallholder passion fruit farmers. Primary data was collected using multistage sampling techniques to arrive at a sample of 141 respondents. Data was analysed using excel for descriptive statistics and gross margin analysis, while STATA was adopted in analysing double hurdle and multinomial logit models. From the findings, selling price, membership in other groups, training on passion fruit enterprise management and distance to the nearest output market positively influenced smallholder farmers’ participation and commitment to collective action, whereas the education level and age of the producer had a negative effect. Further, participation in collective action positively influenced passion fruit enterprise performance. Multinomial logit results on the choice of marketing channel indicated that farmers sold their produce through various channels. Channel choice was influenced by the gender of the producer, payment period, perception of being exploited and selling price. From the findings, it is evident that collective action could improve enterprise performance, which in turn would lead to increased farm revenue and household income. Hence, it is recommended that stakeholders should promote collective action in developing input and output markets for smallholder farmers. Further, it is recommended that policies that strengthen frameworks that guide group membership, and the construction of output markets should be put in place to support collective action and collective marketing among passion fruit farmers.

description: We provide a rigorous derivation of a class of double-hybrid approximations, combining Hartree-Fock exchange and second-order Moller-Plesset correlation with a semilocal exchange-correlation density functional. These double-hybrid approximations contain only one empirical parameter and use a density-scaled correlation energy functional. Neglecting density scaling leads to a one-parameter version of the standard double-hybrid approximations. We assess the performance of these double-hybrid schemes on representative test sets of atomization energies and reaction barrier heights, and we compare to other hybrid approximations, including range-separated hybrids. Our best one-parameter double-hybrid approximation, called 1DH-BLYP, roughly reproduces the two parameters of the standard B2-PLYP or B2GP-PLYP double-hybrid approximations, which shows that these methods are not only empirically close to an optimum for general chemical applications but are also theoretically supported.

description: We investigate tunneling of excitations across a potential barrier separating two spin-1 Bose-Einstein condensates. Using the mean-field theory at the absolute zero temperature, we determine transmission coefficients of excitations in the saturated magnetization state and unsaturated magnetization states. All excitations except the quadrupolar spin mode in the saturated magnetization state show the anomalous tunneling phenomenon characterized as perfect tunneling in the low momentum limit through a potential barrier. The quadrupolar spin mode in the saturated magnetization state, whose spectrum is massive, shows total reflection. We discuss properties common between excitations showing the anomalous tunneling phenomenon. Excitations showing perfect tunneling have gapless spectrum in the absence of the magnetic field, and their wave functions in the low energy limit are the same as the condensate wave function.

The velocity of an atom can be close to the velocity of light. The material properties are taken into account using a single oscillator model of the atomic dynamic polarizability and the Drude dielectric function of a metal substrate. The limit cases of nonrelativistic velocities and an ideal metal substrate are also considered. We have found specific dependence of the calculated forces on the velocity (energy), distance and material properties.

description: iology techniques to analyze its biological information. Fluorescence quantitative PCR technology was used to analyze the expression of exsA after different media stress. [Results] The exsA gene contains an open reading frame (ORF) of 861 bp, encoding 286 amino acids. The physico-chemical analysis shows that the molecular structural formula is C1442H2267N393O441S12, the theoretical molecular weight is 32.549 kD, the theoretical pI value is 6.0, and the protein is non-hydrophilic and unstable. The gene does not contain a transmembrane region, and there is no obvious signal peptide. The prediction result of protein subcellular localization shows that the protein is inside the cell. The deduced amino acid sequence and constructed phylogenetic tree show that V. alginolyticus has a close relationship with Vibrio antiquarius. The qPCR results show that the expression level of exsA in different media is different, highest in TSB medium containing bile salts, followed by DMEM medium, and lowest in ordinary TSB medium. [Conclusions] The gene sequence, molecular structure and isoelectric point of exsA, as well as its expression in three different media were obtained.

description: [Objectives] To establish a non-toxic and efficient method for extracting DNA and total RNA from peanuts and laying a solid foundation for the molecular biology study of peanuts. [Methods] Based on the principle and method of purifying nucleic acids by silica gel adsorption at high salt and low pH condition, a non-toxic and efficient method to extract peanut DNA and total RNA using cetyltrimethyl ammonium bromide (CTAB) extraction solution was designed. The quality and purity of nucleic acids were detected by agarose gel electrophoresis and nucleic acids protein analyzer, respectively. The quality of DNA was further verified by enzyme digestion and PCR amplification using molecular marker techniques. The quality of total RNA was further verified by reverse transcription (RT)-PCR of actin gene and cDNA-SCoT gene differential display technique. [Results] The agarose gel electrophoresis test showed that the peanut DNA extracted by a low-toxic and effective method is free of contamination and degradation. Through the detection by the nucleic acid protein analyzer, the DNA concentration, yield, A260/A280 and A260/A230 of 5 peanut varieties were 419.6-498.2 ng/μL, 20.98-24.91 μg/g, 1.89-1.96 and 2.03-2.28, respectively. The DNA was of high quality and can be completely digested by EcoRI restriction enzymes, and also can be used for SCoT and SRAP molecular marker technology analysis. The RNA extracted from different tissues of peanuts showed no visible DNA bands by non-denaturing agarose gel electrophoresis. The separated 28S bands were brighter than 18S. The ratio of A260/A280 and A260/A230 showed that the RNA quality was good and can be used for reverse transcription, RT-PCR of actin gene and amplification of cDNA-SCoT gene differential display technique. [Conclusions] This experiment established a low-toxic and effective method for extracting DNA and total RNA from peanuts. Compared with traditional methods, this method is more time-saving and cheaper than commercial kits. The most important point is that this method does not use toxic reagents such as phenol, chloroform and isopropanol. Thus, it is expected to be widely applied in molecular biology research.
The practice of everyday crimefighting : urban space in three eras of Batman comics

description: This thesis project uses the spatial theory of Michel de Certeau’s The Practice of Everyday Life to articulate an incipient delinquency in the movement of the superhero – in this case, The Batman – by examining three different serial runs of comic: the Golden Age pulp of the 1940s, Frank Miller’s seminal The Dark Knight Returns (1986) and Scott Snyder’s 2011 “Court of Owls” story arc. The attendant images of diegetic urban space are crucial to this analysis and, by examining the narratives imbued therein, offer a new approach to the superhero comic beyond mere historical referent.
The discrete adjoint method for high-order time-stepping methods
Creators: name: Rothauge, Kai
Publisher: name: University of British Columbia
Year: 2017

description: This thesis examines the derivation and implementation of the discrete adjoint method for several time-stepping methods. Our results are important for gradient-based numerical optimization in the context of large-scale model calibration problems that are constrained by nonlinear time-dependent PDEs. To this end, we discuss finding the gradient and the action of the Hessian of the data misfit function with respect to three sets of parameters: model parameters, source parameters and the initial condition. We also discuss the closely related topic of computing the action of the sensitivity matrix on a vector, which is required when performing a sensitivity analysis. The gradient and Hessian of the data misfit function with respect to these parameters requires the derivatives of the misfit with respect to the simulated data, and we give the procedures for computing these derivatives for several data misfit functions that are of use in seismic imaging and elsewhere. The methods we consider can be divided into two categories, linear multistep (LM) methods and Runge-Kutta (RK) methods, and several variants of these are discussed. Regular LM and RK methods can be used for ODE systems arising from the semi-discretization of general nonlinear time-dependent PDEs, whereas implicit-explicit and staggered variants can be applied when the PDE has a more specialized form. Exponential time-differencing RK methods are also discussed. The implementation of the associated adjoint time-stepping methods is discussed in detail. Our motivation is the application of the discrete adjoint method to high-order time-stepping methods, but the approach taken here does not exclude lower-order methods. All of the algorithms have been implemented in MATLAB using an object-oriented design and are written with extensibility in mind. For exponential RK methods it is illustrated numerically that the adjoint methods have the same order of accuracy as their corresponding forward methods, and for linear PDEs we give a simple proof that this must always be the case. The applicability of some of the methods developed here to pattern formation problems is demonstrated using the Swift-Hohenberg model.

description: We study kinetic mixing between massless U(1)s in toroidal orbifolds with D3-branes at orbifold singularities. We focus in particular on C^3/Z_4 singularities but also study C^3/Z_6 and C^3/Z'_6 singularities. We find kinetic mixing can be present and describe the conditions for it to occur. Kinetic mixing comes from winding modes in the N=2 sector of the orbifold. If kinetic mixing is present its size depends only on the complex structure modulus of the torus and is independent of the Kähler moduli. We also study gauge threshold corrections for local Z_M x Z_N orbifold models finding that, consistent with previous studies, gauge couplings run from the bulk winding scale rather than the string scale.

Constraining tidal dissipation in F-type main-sequence stars: the case of CoRoT-11

description: Tidal dissipation in late-type stars is presently poorly understood and the study of planetary systems hosting hot Jupiters can provide new observational constraints to test proposed theories. We focus on systems with F-type main-sequence stars and find that the recently discovered system CoRoT-11 is presently the best suited for such a kind of investigation. A classic constant tidal lag model is applied to reproduce the evolution of the system from a plausible nearly synchronous state on the ZAMS to the present state, thus putting constraints on the average modified tidal quality factor of its F6V star. Initial conditions with the stellar rotation period longer than the orbital period of the planet can be excluded on the basis of the presently observed state in which the star spins faster than the planet orbit. It is found that is approximately between 4.0E+06 and 2.0E+07 if the system started its evolution on the ZAMS close to synchronization with an uncertainty related to the constant tidal lag hypothesis and the estimated stellar magnetic braking within a factor of about 5-6. Moreover, we discuss how the present value of Q'_s can be measured by a timing of the mid-epoch and duration of the transits as well as of the planetary eclipses to be observed in the infrared with an accuracy of about 0.5-1 s over a time baseline of about 25 yr. CoRoT-11 is an highly interesting system potentially allowing us a direct measure of the tidal dissipation in an F-type star as well as the detection of the precession of the orbital plane of the planet that provides us with an accurate upper limit for the obliquity of the stellar equator. If the planetary orbit has a significant eccentricity (e>0.05), it will be possible to detect also the precession of the line of the apsides and derive information on the Love number of the planet and its tidal quality factor.

description: We study the covariance matrix of the cluster mass function in cosmology. We adopt a two-line attack: firstly, we employ the counts-in-cells framework to derive an analytic expression for the covariance of the mass function. Secondly, we use a large ensemble of N-body simulations in the LCDM framework to test this. Our theoretical results show that the covariance can be written as the sum of two terms: a Poisson term, which dominates in the limit of rare clusters; and a sample variance term, which dominates for more abundant clusters. Our expressions are analogous to those of Hu & Kravtsov (2003) for multiple cells and a single mass tracer. Calculating the covariance depends on: the mass function and bias of clusters, and the variance of mass fluctuations within the survey volume. The predictions show that there is a strong bin-to-bin covariance between measurements. In terms of the cross-correlation coefficient, we find r~0.5 for haloes with M<3e14 Msol at z=0. Comparison of these predictions with estimates from simulations shows excellent agreement. We use the Fisher matrix formalism to explore the cosmological information content of the counts. We compare the Poisson likelihood model, with the more realistic likelihood model of Lima & Hu (2004), and all terms entering the Fisher matrices are evaluated using the simulations. We find that the Poisson approximation should only be used for the rarest objects, M>3e14 Msol, otherwise the information content of a survey of size V~13.5 [Gpc/h]^3 would be overestimated, resulting in errors that are ~2 times smaller. As an auxiliary result, we show that the bias of clusters, obtained from the cluster-mass cross-variance, is linear on scales >50 Mpc/h, whereas that obtained from the auto-variance is nonlinear.

description: The hadron string dynamics (HSD) model is generalized to include the creation and evolution of retarded electromagnetic fields as well as the influence of the magnetic and electric fields on the quasiparticle propagation. The time-space structure of the fields is analyzed in detail for non-central Au+Au collisions at $\sqrt{s_{NN}}=$200 GeV. It is shown that the created magnetic field is highly inhomogeneous but in the central region of the overlapping nuclei it changes relatively weakly in the transverse direction. For the impact parameter $b=$10 fm the maximal magnetic field - perpendicularly to the reaction plane - is obtained of order $eB_y/m_π^2\sim$5 for a very short time $\sim$ 0.2 fm/c, which roughly corresponds to the time of a maximal overlap of the colliding nuclei. We find that at any time the location of the maximum in the $eB_y$ distribution correlates with that of the energy density of the created particles. In contrast, the electric field distribution, being also highly inhomogeneous, has a minimum in the center of the overlap region. Furthermore, the field characteristics are presented as a function of the collision energy and the centrality of the collisions. To explore the effect of the back reaction of the fields on hadronic observables a comparison of HSD results with and without fields is exemplified. Our actual calculations show no noticeable influence of the electromagnetic fields - created in heavy-ion collisions - on the effect of the electric charge separation with respect to the reaction plane.

description: We consider a class of geometrically frustrated Heisenberg spin systems which admit exact ground states. The systems consist of suitably coupled antiferromagnetic spin trimers with integer spin quantum numbers $s$ and their ground state $Φ$ will be the product state of the local singlet ground states of the trimers. We provide linear equations for the inter-trimer coupling constants which are equivalent to $Φ$ being an eigenstate of the corresponding Heisenberg Hamiltonian and sufficient conditions for $Φ$ being a ground state. The classical case $s\to\infty$ can be completely analyzed. For the quantum case we consider a couple of examples, where the critical values of the inter-trimer couplings are numerically determined. These examples include chains of corner sharing tetrahedra as well as certain spin tubes. $Φ$ is proven to be gapped in the case of trimer chains. This follows from a more general theorem on quantum chains with product ground states.

description: In the last 30 years, over a billion azithromycin prescriptions have been dispensed since its approval in the US. The drug was once considered the safest macrolide, but ten years after its approval, evidence from case reports suggested a concern cardiac events and eath with its use. In three different studies, we measured the impact of the FDA warning in the use of azithromycin among high-risk patients, identified the baseline predictors of cardiac events among azithromycin users, and compared the risk of cardiac events with azithromycin and amoxicillin users. In the first study, we observed statistically lower prevalence rates of the cardiac risk factors after the FDA warning; however, the absolute prevalence remained similar before and after the warning. In the second study, we identified consistent predictors of the outcome, which included age, sex, history of syncope, cardiac dysrhythmias, non-specific chest pain, and presence of a concurrent QT-prolonging drug. From this list, we created a tool to ease the process of finding patients at a higher risk of cardiac events. In the third study, we evaluated the risk of cardiac events with azithromycin compared to amoxicillin. Using an active comparator, new user design in a large cohort of over 4 million episodes of azithromycin and amoxicillin, we found no increased risk of cardiac events with azithromycin. In sub-group analyses, the risk was 40% higher among patients prescribed concurrent QT-prolonging drugs. The finding of no increased risk was consistent across several other subgroup analyses. We used real-world data to measure the prevalence of cardiac risk factors before and after the FDA warning, quantified the predictors of cardiac risk factors, and evaluated the risk of cardiac risks with azithromycin compared to amoxicillin. We found that there was no change in prevalence of risk factors after the FDA warning, specific baseline patient characteristics put patients treated with azithromycin at a higher risk of cardiac events, and there was an increased risk of cardiac events with azithromycin compared to amoxicillin. Although the risk is rare, providers should avoid the use of QT-prolonging drugs with azithromycin. Future research should focus on examining the risk of cardiac deaths among azithromycin users.

description: In dieser Arbeit wurden an einem Großmotor Untersuchungen der Zylinderinnenströmung, der Kraftstoffeinspritzung, der Gemischbildung / Zündung und der Verbrennung / Emissionsbildung durchgeführt. Neben den klassischen Entwicklungswerkzeugen wie der Zylinderdruckindizierung und der Abgasemissionsmessung kamen laseroptische Messtechniken und ein 3D-CFD-Modell zum Einsatz. Durch deren Kombination konnte ein umfassendes Bild der Verbrennung in mittelschnelllaufenden Dieselmotoren gewonnen werden.
Lectures on F-theory compactifications and model building

description: These lecture notes are devoted to formal and phenomenological aspects of F-theory. We begin with a pedagogical introduction to the general concepts of F-theory, covering classic topics such as the connection to Type IIB orientifolds, the geometry of elliptic fibrations and the emergence of gauge groups, matter and Yukawa couplings. As a suitable framework for the construction of compact F-theory vacua we describe a special class of Weierstrass models called Tate models, whose local properties are captured by the spectral cover construction. Armed with this technology we proceed with a survey of F-theory GUT models, aiming at an overview of basic conceptual and phenomenological aspects, in particular in connection with GUT breaking via hypercharge flux.

hybrid
maternal component¸ paternal form

description: In the course of research, six forms of different types of fescue were selected: red fescue, blue fescue, sheep fescue, which differ in markers and leaf color, panicles and stems from varieties of fescue of the respective species. which causes stable changes in the color of the leaf blade surface from green to blue with slight shades. It is established that the color of the plate of the fescue leaf is controlled by plasma genes that are transmitted through the maternal line. Regardless of the color of the leaf blade of the parent component of the cross, the color of the hybrid is determined by the embryonic plasma of the parent component.

description: Based on isobaric tags for relative and absolute quantification (iTRAQ) technology, the proteome of grains of a maize cultivar Huangzao 4 under drought stress at grain filling stage was analyzed. The results show that under drought stress, 438 proteins were differentially expressed in the maize grains during grain filling. Among them, 200 were up-regulated and 238 were down-regulated. The gene ontology (GO) analysis shows that the biological processes in which differential proteins are more involved are cellular processes, metabolic processes and single biological processes; proteins in the cell component category are mainly distributed in cells, cell parts and organelles; and the proteins the molecular function category mainly possess catalytic activity and binding function. Differentially expressed proteins classified by COG are mainly involved in protein post-translational modification and transport, molecular chaperones, general functional genes, translation, ribosomal structure, biosynthesis, energy production and transformation, carbohydrate transport and metabolism, amino acid transport and metabolism, etc. The subcellular structure of the differentially expressed proteins is mainly located in the cell chloroplast and cytosol. The proportions are 35.01% and 30.21% respectively. KEGG metabolic pathway enrichment analysis shows that the differentially expressed proteins are mostly involved in antibiotic biosynthesis, microbial metabolism in different environments, and endoplasmic reticulum protein processing; the metabolic pathways with higher enrichment are the carbon fixation pathway and estrogen signaling pathway of prokaryotes; and the higher enrichment and greater significance are in the tricarboxylic acid cycle, carbon fixation of photosynthetic organisms and proteasome. The results of this study preliminarily reveal the adaptive mechanism of maize grains in response to drought stress during grain filling, providing a theoretical reference for maize drought-resistant molecular breeding.

description: Results for next-to-leading order QCD corrections to the pp(p\bar{p}) -> t \bar{t} -> W^+W^- b\bar{b} -> e^{+} ν_{e} μ^{-} \barν_μ b \bar{b} +X processes with complete off-shell effects are presented for the first time. Double-, single- and non-resonant top contributions of the order {\cal{O}}(α_{s}^3 α^4) are consistently taken into account, which requires the introduction of a complex-mass scheme for unstable top quarks. Moreover, the intermediate W bosons are treated off-shell. Comparison to the narrow width approximation for top quarks, where non-factorizable corrections are not accounted for is performed. Besides the total cross section and its scale dependence, several differential distributions at the TeVatron run II and the LHC are given. In case of the TeVatron the forward-backward asymmetry of the top is recalculated afresh. With inclusive selection cuts, the forward-backward asymmetry amounts to A^{t}_{FB} = 0.051 +/- 0.0013. Furthermore, the corrections with respect to leading order are positive and of the order 2.3% for the TeVatron and 47% for the LHC. A study of the scale dependence of our NLO predictions indicates that the residual theoretical uncertainty due to higher order corrections is 8% for the TeVatron and 9% for the LHC.

Higher particle form factors of branch point twist fields in integrable quantum field theories

description: In this paper we compute higher particle form factors of branch point twist fields. These fields were first described in the context of massive 1+1-dimensional integrable quantum field theories and their correlation functions are related to the bi-partite entanglement entropy. We find analytic expressions for some form factors and check those expressions for consistency, mainly by evaluating the conformal dimension of the corresponding twist field in the underlying conformal field theory. We find that solutions to the form factor equations are not unique so that various techniques need to be used to identify those corresponding to the branch point twist field we are interested in. The models for which we carry out our study are characterized by staircase patterns of various physical quantities as functions of the energy scale. As the latter is varied, the beta-function associated to these theories comes close to vanishing at several points between the deep infrared and deep ultraviolet regimes. In other words, renormalisation group flows approach the vicinity of various critical points before ultimately reaching the ultraviolet fixed point. This feature provides an optimal way of checking the consistency of higher particle form factor solutions, as the changes on the conformal dimension of the twist field at various energy scales can only be accounted for by considering higher particle form factor contributions to the expansion of certain correlation functions.
