description: Motivated by a recent proposal on the possibility of observing a monopole in the band structure, and by an increasing interest on the role of Berry phase in spintronics, we studied the adiabatic motion of a wave packet of Bloch functions, under a perturbation varying slowly and incommensurately to the lattice structure. We show using only the fundamental principles of quantum mechanics that its effective wave-packet dynamics is conveniently described by a set of equations of motion (EOM) for a semiclassical particle coupled to a nonabelian gauge field associated with a geometric Berry phase. Our EOM can be viewed as a generalization of the standard Ehrenfest's theorem, and their derivation was asymptotically exact in the framework of linear response theory. Our analysis is entirely based on the concept of local Bloch bands, a good starting point for describing the adiabatic motion of a wave packet. One of the advantages of our approach is that the various types of gauge fields were classified into two categories by their different physical origin: (i) projection onto specific bands, (ii) time-dependent local Bloch basis. Using those gauge fields, we write our EOM in a covariant form, whereas the gauge-invariant field strength stems from the noncommutativity of covariant derivatives along different axes of the reciprocal parameter space. The degeneracy of Bloch bands makes the gauge fields nonabelian. We applied our formalism to the analyses on various types of Hall and polarization currents. We highlighted their behavior under time reversal (T) and space inversion (I). The concept of parity polarization current was also introduced. Together with charge/spin Hall/polarization currents, this type of orbital current is expected to be a potential probe for detecting and controling Berry phase.

description: Assuming a gravitational origin for the Fe III$λλ$2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we obtain individual measurements of the virial factor, $f$, in 10 quasars. The average values for the Balmer lines, $\langle f_{Hβ}\rangle={\bf 0.43\pm 0.20}$ and $\langle f_{Hα}\rangle={\bf 0.50\pm 0.24}$, are in good agreement with the results of previous studies for objects with lines of comparable widths. In the case of Mg II, consistent results, $f_{Mg II} \sim {\bf 0.44}$, can be also obtained accepting a reasonable scaling for the size of the emitting region. The modeling of the cumulative histograms of individual measurements, $CDF(f)$, indicates a {relatively} high value for the ratio between isotropic and cylindrical motions, $a\sim {\bf 0.4}-0.7$. On the contrary, we find very large values of the virial factor associated to the Fe III$λλ$2039-2113 blend, $f_{FeIII}=14.3\pm2.4$, which can be explained if this feature arises from a flattened nearly face-on structure, similar to the accretion disk.

description: Spatial market equilibrium theory views trade flow as the driving force behind market integration. We assess spatial price transmission between domestic tomato markets in Ghana to ascertain whether spatial price transmission veritably depends on direct trade between markets, or whether other forces drive market integration. We analyze a unique data set on tomato trade consisting of semi-weekly price and trade flow data for the five most important Ghanaian markets for fresh tomato, which represents one of the most important commercially produced and consumed vegetables in the country. A regime-dependent vector error correction model is proposed to investigate this question, and the results are compared with those of a linear vector error correction model. The analysis reveals that prices in net producing areas of Ghana, viz. Navrongo and Techiman, adjust quickly to disequilibria, while prices in most major consuming areas do not show significant error correction. Markets are partly found to be strongly integrated even in periods without direct trade flows. Information exchange among suppliers or third-market effects might offer possible explanations to this finding.

description: A way of constructing a nonlinear filter close to the optimal Kolmogorov - Wiener filter is proposed within the framework of the statistical approach to inverse problems. Quasi-optimal filtering, which has no Bayesian assumptions, produces stable and efficient solutions by relying solely on the internal resources of the inverse theory. The exact representation is given of the Feasible Region for inverse solutions that follows from the statistical consideration.

description: Even after more than 15 years of transition from plan to market, agriculture in Ukraine still faces many challenges in terms of its structure. In particular, both the recently approved WTO accession, and the ongoing negotiations on a free trade agreement with the EU will require improvements in productivity and competitiveness at the farm level. The evidence in the literature based on either data envelopment (DEA) or stochastic frontier analysis (SFA) in Ukraine points to significant heterogeneity of technical efficiency and TFP scores. However, the drivers underlying these patterns have not been explicitly studied yet. Using farm-level data for 2004-2005, this paper investigates the determinants of productivity growth in Ukrainian dairy farming. The results demonstrate significant spatial dependency in pure efficiency and technological components, meaning essentially ‘imitating’ behavior of the neighboring farms in their efficiency and technological progress. Price supports demonstrate negative impact on efficiency, and, however, much weaker positive impact on the technology progress of relatively small farm.

description: Nonperturbative equations of state (EoSs) for two and three quark flavors are constructed with the functional renormalization group (FRG) within a quark-meson model truncation augmented by vector mesons for low temperature and high density. Based on previous FRG studies without repulsive vector meson interactions the influence of isoscalar vector $ω$- and $ϕ$-mesons on the dynamical fluctuations of quarks and (pseudo)scalar mesons is investigated. The grand potential as well as vector meson condensates are evaluated as a function of quark chemical potential and the quark matter EoS in $β$-equilibrium is applied to neutron star (NS) physics. The tidal deformability and mass-radius relations for hybrid stars from combined hadronic and quark matter EoSs are compared for different vector couplings. We observe a significant impact of the vector mesons on the quark matter EoS such that the resulting EoS is sufficiently stiff to support two-solar-mass neutron stars.

description: Cropping pattern in the Himalayan region of India has undergone a significant change in the recent past. Introduction of horticultural crops of vegetables, fruits and flowers have led to more intensive agriculture. Such a change, resulting in higher incomes and improvements of the overall living conditions has, however, been accompanied with increased income risk. This emphasises a need for proper analysis of the cropping pattern, at an appropriate scale, such as, a micro watershed. This was achieved by constructing a dynamic non-linear programming model incorporating appropriate objective function, constraints and crop and livestock activity budgets along with risk component present in the gross returns. The model was then solved under alternate policy scenarios by using General Algebraic Modelling Systems (GAMS) for next 20 years. The optimum cropping plans were then compared with each other and with the existing plan. Tomato and carnation are the preferred crops, if the sole objective is profit maximization. Optimum plan with risk consideration was also assessed by fixing the variance in gross returns at the current level. It reduced the area under tomato in rainy season by growing capsicum and beans. Similarly, peas replaced tomato in winter season and chrysanthemum replaced carnation. By comparing it with the existing plan, it can be inferred that the people are more considerate to risk than the profits. The profits and risks from floriculture are relatively very high as compared to other crops. By removing constraints in credit availability, irrigation facilities, transportation and market yards, large scale production of vegetables and flowers can help in raising the income level.

In this language the celebrated "Menshov representation theorem" states that Z is a Menshov spectrum. In this paper we construct 1) Menshov spectra that are almost exponentially sparse 2) that are almost squares. Then we show that the positive integers are not a Menshov spectrum but are a Menshov spectrum in measure, and repeat 1) and 2) in the analytic settings.

description: The nature of the collective ownership may make it easier for the local governments to purse private benefits from the return of the public investments on the collective operation. This may lead to disproportionate allocation of public funds to favour collective-owned operation as opposed to private production, though such allocation did not always benefit the majority of the villagers. The introduction of election in local governments may decrease the extent of her capture from public investments on the collective, for the reason that the village head needs to take not only the private interest but also the votes into her consideration when allocating the public funds. In this paper, we found evidence that the allocation of the public funds is sensitive to the change of the demographic weight of collective groups although no disproportionate allocation has been assigned to the collective group. And election had no effects on the allocation pattern of the production related public funds.
Personal trust and trust in abstract systems : a study of forest stewardship council-accredited certification in British Columbia
Creators: name: McDermott, Constance Lynn
Publisher: name: University of British Columbia
Year: 2009

description: Forest Stewardship Council-accredited certification in British Columbia arose out of distrust in government and the forest industry as stewards of the province's forest resources. The initiative for forest certification emerged among environmentalists and other interest groups that have been marginalized in mainstream forestry decision-making. Forest certification is a system of green labeling for products that come from environmentally, socially and economically well-managed forests. In other words, certification attempts to redefine appropriate forest management, and build trust where other forestry decision-makers have failed. This dissertation examines how trust is (or is not) built amidst such widely divergent interests. Building trust amidst diversity is a common problem in our increasingly globalized world. In response to this challenge, modern decision-making systems are often built around abstract concepts, such as pluralist democracy and impersonal, rationalistic systems, that are presumably disembedded from social bias. Likewise, the Forest Stewardship Council has developed a pluralist system of standard-setting and an impersonal accreditation system as a means to win the trust of a diversity of forestry interests. The results of this research, based on five years of participant observation and forty in-depth, semi-structured interviews of key interest group members in British Columbia, suggest that the Forest Stewardship Council's "abstract systems" increased trust among some interests. However, these abstract systems did not serve to bridge group differences. Instead, decision-making processes became enmeshed in existing dynamics of distrust. The pluralist standard-setting process empowered previously marginalized interests while exacerbating distrust between some groups. At the same time, impersonal accreditation procedures did not win adequate trust because they did not address the socially embedded causes of distrust. This dissertation concludes that it is the balance of formal abstract systems and flexibility that creates enabling conditions for trust. Abstract systems set boundaries, reduce risk, and can redress power imbalances. They do not by themselves, however, build trust. Flexibility enables voluntary cooperation, which leads to the bridging of differences. In the context of conflicting values and diverse knowledge, therefore, decision-making should be adequately devolved to the on-the-ground implementation level, to allow room for reciprocal acts of voluntary cooperation and the creation of shared meaning.

description: Water User Cooperative Society (WUCS) is an organization of water users administered using the principles of Cooperation. In the Cauvery Basin of Karnataka, 581 WUCS have been registered under Cooperative Society Act. To study the activity and the progress of WUCS, information was collected from the President / Secretary of thirty WUCS in Krishnarajasagar (K.R.S.) and Kabini command of Cauvery basin. Using cluster analysis, WUCS with similar characteristics (explanatory variables) were grouped into three clusters. First cluster of WUCS (20%) is characterized as well performing, with lowest transaction cost of forming WUCS (3 months), high cooperation and fund availability. Second cluster characterized as moderate WUCS (20%) had a transaction cost of 3 months with a total fund of Rs. 21,283. Third cluster as poor performing WUCS (60%) had highest transaction cost of 5 months with fund availability of Rs. 21,950. The head and tail reach farmers of Active-WUCS, Active with conjunctive WUCS (Active-CU WUCS) and Passive-WUCS command were interviewed personally (90 sample farmers). The return of Kharif paddy per rupee of CostB2 in Active-CU-WUCS (1.25) was higher than the Passive-WUCS (1.23) and Active-WUCS (1.18). Similarly, tail reach farmers of Active-CU-WUCS received net returns of Rs. 2,301, followed by Active-WUCS (Rs. 398), but Passive-WUCS incurred economic loss of Rs. 73. ANOVA indicated significant difference in net returns per acre per annum among three WUCS (1%), and t-test indicated significant difference between “Active-CU-WUCS and Passive-WUCS” and “Active-WUCS and Passive-WUCS.” The discriminant function analysis indicated that, the size of holding and the ratio of area irrigated by borewell to total area were the major factors in discriminating members and non-members. Logit regression function for willingness to pay water rate for assured summer irrigation as dependent variable showed, land holding of the farmer and distance of the farm from canal as significant factors. WTP additional water rates for assured irrigation was estimated using Tobit regression which indicated that land holding of the farmer, use of borewell Irrigation and distance of the farm from canal were the significant factors influencing the farmers’ willingness to pay.

Geodesic Loewner paths with varying boundary conditions

Publisher: name: arXiv
Year: 2020
Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: Equations of the Loewner class subject to non-constant boundary conditions along the real axis, are formulated and solved giving the geodesic paths of slits growing in the upper half complex plane. The problem is motivated by Laplacian growth in which the slits represent thin fingers growing in a diffusion field. A single finger follows a curved path determined by the forcing function appearing in Loewner's equation. This function is found by solving an ordinary differential equation whose terms depend on curvature properties of the streamlines of the diffusive field in the conformally mapped `mathematical' plane. The effect of boundary conditions specifying either piecewise constant values of the field variable along the real axis, or a dipole placed on the real axis, reveal a range of behaviours for the growing slit. These include regions along the real axis from which no slit growth is possible, regions where paths grow to infinity, or regions where paths curve back toward the real axis terminating in finite time. Symmetric pairs of paths subject to the piecewise constant boundary condition along the real axis are also computed, demonstrating that paths which grow to infinity evolve asymptotically toward an angle of bifurcation of $π/5$.

Modeling feedback from stars and black holes in galaxy mergers

Subjects: subject: Astrophysics (astro-ph)

description: We describe techniques for incorporating feedback from star formation and black hole accretion into simulations of isolated and merging galaxies. At present, the details of these processes cannot be resolved in simulations on galactic scales. Our basic approach therefore involves forming coarse-grained representations of the properties of the interstellar medium and black hole accretion starting from basic physical assumptions, so that the impact of these effects can be included on resolved scales. We illustrate our method using a multiphase description of star-forming gas. Feedback from star formation pressurises highly overdense gas, altering its effective equation of state. We show that this allows the construction of stable galaxy models with much larger gas fractions than possible in earlier numerical work. We extend the model by including a treatment of gas accretion onto central supermassive black holes in galaxies. Assuming thermal coupling of a small fraction of the bolometric luminosity of accreting black holes to the surrounding gas, we show how this feedback regulates the growth of black holes. In gas-rich mergers of galaxies, we observe a complex interplay between starbursts and central AGN activity when the tidal interaction triggers intense nuclear inflows of gas. Once an accreting supermassive black hole has grown to a critical size, feedback terminates its further growth, and expels gas from the central region in a powerful quasar-driven wind. Our simulation methodology is therefore able to address the coupled processes of gas dynamics, star formation, and black hole accretion during the formation of galaxies.

The evolution of inbreeding in western redcedar (Thuja plicata : Cupressaceae)
Creators: name: O’Connell, Lisa Marie
Publisher: name: University of British Columbia
Year: 2009

description: Long-lived woody plants usually show high levels of outcrossing, inbreeding depression and genetic diversity compared to other plants. A review of the literature showed a mean outcrossing rate of 83.5 in conifers, and a positive, but weak, correlation between outcrossing and genetic diversity. Among conifers, western redcedar (Thuja plicata, Cupressaceae) has one of the highest rates of self-fertilization and lowest amount of genetic diversity, and thus offers the opportunity to study the evolution of inbreeding in a predominantly outcrossing group of plants. This thesis links the evolution of inbreeding in redcedar with a loss in inbreeding depression and genetic diversity. Using one polymorphic isozyme marker, I obtained an average population outcrossing estimate of 71% over six natural populations of redcedar. I developed 13 highly polymorphic microsatellite markers to conduct a finer-scale study of the mating system and genetic structure of redcedar. A new method of bulking seedlings to estimate outcrossing rates was used to identify ecological correlates of outcrossing. Selfing rates increased significantly with tree height in four different populations. Pollen from larger trees probably made up a larger proportion of the surrounding pollen cloud, increasing self-pollination. There was no variation, however, in the amount of inbreeding among crown positions within trees. In a seed orchard, a combination of controlled crosses and isozyme markers showed evidence that post-pollination competition between embryos within an ovule decreased selfing. I used eight microsatellite loci to study patterns of range-wide genetic structure in redcedar. A phylogeographic analysis suggests that redcedar probably survived in three separate refugia during the last glaciation. These results also suggest that if a species-wide bottleneck is at the root of reduced genetic diversity in redcedar, it probably predates the last glaciation. The combination of an inbreeding mode of reproduction and a bottleneck probably contributed to the decrease in genetic diversity presently observed in redcedar. Finally, after screening 80 trees at eight microsatellite loci, a single stepwise mutation was observed, yielding a somatic mutation rate of 6.3 x 10-4 (95% CI: 3.0 x 10-5 - 4.0 x 10-3) mutations per locus per generation in western redcedar.

description: We consider the renormalization in the pseudo-scalar inflation models with the gravitational Chern-Simons term. In this model, lepton asymmetry is generated from the chiral gravitational waves produced due to the Chern-Simons term through the gravitational chiral anomaly. However, it is known that the naive estimate of the expectation value of the gravitational Chern-Pontryagin density as well as the resultant lepton number density depend on the UV-cutoff scale, which raises a question on their validity. In this paper, we propose a way to renormalize the expectation value of the Chern-Pontryagin density to remove the UV-cutoff dependence. We also discuss the renormalized lepton number density when we adopt the minimal subtraction scheme and the viability of the gravitational leptogenesis scenario.

description: For applications in agricultural economics, complex ecological systems are often oversimplified to the extent that ecologists rarely consider model results valid. Recursive optimization of complex systems represents an alternative, but requires strong assumptions regarding time preference and uncertainty. In this paper we explore the implications of merely approximating “true” optima of complex dynamic optimization problems using a technique called simulation-optimization. We develop a standard discrete renewable resource use problem and solve it numerically using both simulation-optimization and non-linear mathematical programming. We subsequently introduce non-linearity and uncertainty and graphically compare the performance of simulation-optimization vis-à-vis non-linear programming in predicting optimal control and state variable paths. On the basis of this comparison we discuss potential non-formal test procedures that could be used to assess simulation-optimization solutions of more complex problems that do not allow for such comparisons. We find that simulation-optimization can be a useful exploratory optimization technique when standard numerical optimization approaches fail to find near optimal solutions. That said, modelers should be careful in designing management functions of simulation-optimization problems and test their functional forms for severe misspecifications.

description: We report high resolution (R~37,000) integral field spectroscopy of the central region (r<14arcsec) of the Red Rectangle nebula surrounding HD44179. The observations focus on the 5800A emission feature, the bluest of the yellow/red emission bands in the Red Rectangle. We propose that the emission feature, widely believed to be a molecular emission band, is not a molecular rotation contour, but a vibrational contour caused by overlapping sequence bands from a molecule with an extended chromophore. We model the feature as arising in a Polycyclic Aromatic Hydrocarbon (PAH) with 45-100 carbon atoms.

description: Five species of reptiles present in tropical Australia are considered in this study. These are the hawksbill turtle (Eretmochelys imbricata); the northern long-necked turtle (Chelodina rugosa); the taipan snake (Oxyuranus scutellatus); the freshwater crocodile (Crocodylus johnstoni); and the saltwater crocodile (Crocodylus porosus). Background information is provided on the ecological status of each of these species and after outlining their human use (including commercial use) and management in Australia, an experimental survey method is introduced and results from its application are reported and analysed. The survey method involves two serial surveys of a sample of 204 Brisbane (Australia) residents. The first survey is based on the initial knowledge of the respondents of the reptile species and for the subsequent survey the knowledge available to participants about these species is experimentally increased. These surveys provide information on the amount of knowledge possessed by this sample of the public about the relevant reptile species, the respondents’ attitudes to these species (including their attitudes to commercial use), respondents’ support for the survival of these reptiles and for their conservation. Furthermore, data is gathered from the surveys on the comparative amount respondents’ state they would be prepared to contribute to support the conservation of each of these focal reptile species. Respondents are asked to assume that they are given $1,000 and that this can only be allocated to the conservation of these reptiles. Later, however, they are also given the option to donate this money to any charity concerned with human welfare. The contingent valuation data for each of the reptile species are used to isolate factors that influence the comparative allocation of conservation funds to each of the relevant reptile species. Factors considered include the extent of the respondents’ knowledge of the species, the stated degree to which respondents’ reported that they liked or disliked the species, and ethical views of the respondents. Implications of the findings for the theory of economic valuation of wildlife species and for of the focal reptile species in Australia are discussed in concluding this chapter.

description: Inflationary homogeneous isotropic cosmological models filled by scalar fields and ultrarelativistic matter are examined in the framework of gauge theories of gravitation. By using quadratic scalar field potential numerical analysis of flat, open and closed models is curried out. Properties of cosmological models are investigated in dependence on indefinite parameter of cosmological equations and initial conditions at a bounce. Fulfilled analysis demonstrates regular character of all cosmological models.

description: An experiment involving 204 residents of Brisbane, Australia is outlined and the results are reported and analysed. Two consecutive surveys of the respondents provide data about their stated knowledge of 23 wildlife species present in tropical Australia, many of which exclusively occur there. In addition, these surveys provide data about the willingness of respondents to pay for the conservation of those species belonging to three taxa: reptiles, mammals, and birds. The respondents’ stated knowledge of the species is compared with their willingness to pay for species’ conservation, and relevant inferences are drawn. When the respondents’ knowledge of the species is experimentally increased in a balanced way, it is found to result in more dispersion (greater discrimination) in respondents’ willingness to contribute to conservation of the different wildlife species in the set considered. A set of factors likely to be important in influencing individuals’ support for the conservation of wildlife species is identified and there is critical comment on recent valuation literature. Both theoretical and policy conclusions are drawn from the results.
Deflection Angle and Shadow Behaviors of Quintessential Black Holes in arbitrary Dimensions

description: Motivated by M-theory/superstring inspired models, we investigate certain behaviors of the deflection angle and the shadow geometrical shapes of higher dimensional quintessential black holes associated with two values of the dark energy (DE) state parameter, being ω=-\frac{1}{3} and ω=-\frac{2}{3}. Concretely, we derive the geodesic equation of photons on such backgrounds. Thanks to the Gauss-Bonnet theorem corresponding to the optical metric, we compute the leading terms of the deflection angle in the so-called weak-limit approximation. After that, we inspect the effect of DE and the space-time dimension d on the calculated optical quantities. Introducing DE via the field intensity c and the state parameter ω, we find that the shadow size and the deflection angle increase by increasing values of the field intensity c. However, we observe that the high dimensions decrease such quantities for ω-models exhibiting similar behaviors. Then, we consider the effect of the black hole charge, on these optical quantities, by discussing the associated behaviors. The present investigation recovers certain known results appearing in ordinary four dimensional models.

description: We consider the open online dial-a-ride problem, where transportation requests appear online in a metric space and need to be served by a single server. The objective is to minimize the completion time until all requests have been served. We present a new, parameterized algorithm for this problem and prove that it attains a competitive ratio of $1 + φ\approx 2.618$ for some choice of its parameter, where $φ$ is the golden ratio. This improves the best known bounds for open online dial-a-ride both for general metric spaces as well as for the real line. We also give a lower bound of~$2.457$ for the competitive ratio of our algorithm for any parameter choice.

description: We analyze two-loop gluino corrections to the neutron electric dipole moment (EDM) in the minimal supersymmetry extension of the standard model (MSSM). The dependence of two-loop corrections on the relevant CP violating phases differs from that of the one-loop contributions, and there is a region in the parameter space where the two-loop contributions are comparable with the one-loop contributions. Our numerical results show that the two-loop corrections can be as large as 30% of the one-loop results.

description: The interplay between different degrees of freedom governs the emergence of correlated electronic states in quantum materials, with charge density waves (CDW) often coexisting with other exotic phases. Under thermal equilibrium, traditional CDW states are consequentially accompanied by structural phase transitions. In contrast, ultrafast photoexcitation allows access to exotic states where a single degree of freedom dominates in the time domain, enabling the study of underlying physics without interference. Here, we report the realization of a long-lived metastable CDW state without lattice distortion at the photoinduced interfaces in GdTe3 using time- and angle-resolved photoemission spectroscopy. After optical excitation above the CDW melting threshold, we identified emerged metastable interfaces through inverting the CDW-coupled lattice distortions, with lifetimes on the order of 10 picoseconds. These photoinduced interfaces represent a novel CDW state lacking the usual amplitude mode and lattice distortions, allowing quantification of the dominant role of electronic instabilities in CDW order. This work provides a new approach to disentangling electronic instabilities from electron-phonon coupling using a nonequilibrium method.
