description: In recent years, in the field of consumer behaviour, a large number of new models and instruments for preference analysis have been proposed. This strand of the literature has developed along two different lines. The first has produced approaches that have a more solid economic basis, but which at the same time require increasingly complex econometric analysis. Moreover, in this research field, based on stochastic utility theory and choice experiments, less weight is given to the socio-economic and psychometric characteristics of the individual in determining preferences. By contrast, the second strand has given rise to many methods to analyse consumer behaviour based on quality approaches such as laddering or focus groups where behavioural characteristics and lifestyles have regained primary importance in explaining the choices and “tastes” of individuals.

description: Local inversions are often observed in the heliospheric magnetic field (HMF), but their origins and evolution are not yet fully understood.Parker Solar Probe has recently observed rapid, Alfvenic, HMF inversions in the inner heliosphere, known as 'switchbacks', which have been interpreted as the possible remnants of coronal jets. It has also been suggested that inverted HMF may be produced by near-Sun interchange reconnection; a key process in mechanisms proposed for slow solar wind release. These cases suggest that the source of inverted HMF is near the Sun, and it follows that these inversions would gradually decay and straighten as they propagate out through the heliosphere. Alternatively, HMF inversions could form during solar wind transit, through phenomena such velocity shears, draping over ejecta, or waves and turbulence. Such processes are expected to lead to a qualitatively radial evolution of inverted HMF structures. Using Helios measurements spanning 0.3-1 AU, we examine the occurrence rate of inverted HMF, as well as other magnetic field morphologies, as a function of radial distance A, and find that it continually increases. This trend may be explained by inverted HMF observed between 0.3-1 AU being primarily driven by one or more of the above in-transit processes, rather than created at the Sun. We make suggestions as to the relative importance of these different processes based on the evolution of the magnetic field properties associated with inverted HMF. We also explore alternative explanations outside of our suggested driving processes which may lead to the observed trend.

The spin-polarized ferromagnetic state of a cold Fermi gas

description: The spin-polarized ferromagnetic state of a cold Fermi gas is investigated for interacting and non-interacting charge-neutral and $β$-equilibrated gases. The standard minimal couplings between the magnetic field and the fermions' charges and magnetic dipole moments define the fermions' interaction with the magnetic field. Assuming a variable coupling strength between the magnetic field and the fermion (baryon) dipole moments, it is shown that a ferromagnetized state can be achieved that corresponds to a lower energy spin-polarized state with a magnetic field entirely due to the gas's magnetic response. We find that, depending on the density, a very large increase in the baryon dipole moments is needed to achieve this ferromagnetized state. While the required increase seems unlikely, the induced magnetic field is of the order $\sim10^{17}$ gauss. Furthermore, while externally magnetized Fermi gases have an anisotropic pressure, the pressure of the ferromagnetized gas is completely isotropic and the thermodynamically preferred magnetized state.

Institutional arrangements for improved governance of community watersheds on the Sunshine Coast of B.C.
Creators: name: Shay, Heather Marie
Publisher: name: University of British Columbia
Year: 2009

description: There is a growing recognition that watersheds are important physical units for implementing sustainability. Many communities and policy makers are recognizing the benefits to adopting a watershed-based approach for problem solving and resource management. What many researchers ignore, however, are the institutional arrangements and governance structures needed to implement a new, participatory, community based process. This research analyzes the institutional arrangements involved in the historical management and planning of the Chapman and Gray Creek watersheds, on the Sunshine Coast of British Columbia. Drawing from principles of institutional analysis, multistakeholder decision making, community based watershed management and public participation, the thesis concludes that an institutional analysis and development framework is a useful tool for ecosystem-based practitioners, and provides useful techniques for determining gaps and strengths in watershed governance efforts. The emphasis on community attributes is a strength of the framework; one which is readily apparent in analyzing the nature and history of watershed management on the Sunshine Coast. Additionally, the consideration of transaction costs, including those related to information access and sharing, coordination and collaboration; and strategic costs such as rent seeking and turf protecting, was essential to understanding the nature of interorganizational dynamics, rule systems, and decision making patterns over the history of the management of the Chapman and Grey Creek watersheds. Understanding these dynamics is crucial in identifying areas that show potential for future conflict, as well as areas that should be strengthened and built upon. This case study also demonstrates that governments must move away from stakeholder involvement that seeks to primarily legitimize government decisions or the interests of a selected group, to processes that involve the stakeholders in identifying the issues and proposing possible answers. Additionally, there needs to be a movement away from "closed door" decision making to a more participatory, democratic approach, where the public and affected stakeholders have an opportunity to truly participate and influence government decision making.
Numerical study of polymer tumbling in linear shear flows

description: We investigate numerically the dynamics of a single polymer in a linear shear flow. The effects of thermal fluctuations and randomly fluctuating velocity gradients are both analyzed. Angular, elongation and tumbling time statistics are measured numerically. We perform analytical calculations and numerical simulations for a linear single-dumbbell polymer model comparing the results with previous theoretical and experimental studies. For thermally driven polymers the balance between relaxation and thermal fluctuations plays a fundamental role, whereas for random velocity gradients the ratio between the intensity of the random part and the mean shear is the most relevant quantity. In the low-noise limit, many universal aspects of the motion of a polymer in a shear flow can be understood in this simplified framework.

description: Automation and artificial intelligence (AI) are radically changing marketing tactics in the quickly growing quick commerce (q-commerce) and traditional e-commerce industries. Examining how these technologies affect customer acquisition, hyper-personalization, dynamic content creation, programmatic advertising, predictive inventory management, and AI-powered customer service, this study explores the disruptive effects of these technologies throughout the marketing value chain. We examine how real-time interaction, smart consumer segmentation, and optimal marketing expenditure are made possible by AI-powered solutions, which increase customer experiences and return on investment. The study specifically examines the crucial role that AI and automation play in the fast-paced world of q-commerce, where quick satisfaction demands flexible marketing strategies. We examine how these technologies support automated order fulfilment communication, efficient last-mile delivery, and micro-moment targeting—all of which are essential for preserving a competitive edge. Beyond the advantages, this study evaluates the ethical issues and problems brought about by the extensive use of AI and automation in online retail marketing. These issues include algorithmic bias, data security, and the changing skill sets needed by marketing professionals in this technologically advanced age. In the end, this abstract highlights how AI and automation have the revolutionary potential to reshape customer engagement and marketing efficacy in the rapidly changing e-commerce and fast commerce ecosystem.

For $x<0.13$ the system's ground state is insulating canted antiferromagnetic. For $0.13\le x \le 0.175$ e below the Jahn Teller transition temperature ($T_{\rm JT}$) the crystal structure undergoes a monoclinic distortion. The crystal structure can be described with $P 2_1/c$ space group which permits two Mn sites. The unit cell strain parameter $s=2(a-c)/(a+c)$ increases for $Ta>b/\sqrt{2}$) structure.

description: Several ultra-compact accurate wave functions in the form of generalized Hylleraas-Kinoshita functions and Guevara-Harris-Turbiner functions, which describe the domain of applicability of the Quantum Mechanics of Coulomb Charges (QMCC), or, equivalently, the Non-Relativistic QED (NRQED), for the ground state energies (4-5 significant digits (s.d.)) of He-like and Li-like iso-electronic sequences in the static approximation with point-like, infinitely heavy nuclei are constructed. It is shown that for both sequences the obtained parameters can be fitted in $Z$ by simple smooth functions: in general, these parameters differ from the ones emerging in variational calculations. For the He-like two-electron sequence the approximate expression for the ground state function, which provides absolute accuracy for the energy $\sim 10^{-3}$\,a.u. and the same relative accuracies $\sim 10^{-2}-10^{-3}$ for both the cusp parameters and the six expectation values, is found. For the Li-like three-electron sequence the most accurate ultra-compact function taken as the variational trial function provides absolute accuracy for energy $\sim 10^{-3}$\,a.u., 2-3 s.d. for the electron-nuclear cusp parameter for $Z \leq 20$ and 3 s.d. for the two expectation values for $Z=3$.

CHANGES IN THE NUMBER AND CHARACTERISTICS OF FARMS IN NORTH CAROLINA

Publisher: name: Unknown
Year: 1997
Subjects: Farm Management

description: This report contains estimates of the number of new farms and the number of exits from farming in North Carolina for various periods of time between 1978 and 1992. Entrance and exit rates are based on the latest information provided by the Census of Agriculture about the total number of farms in each county as well as the number of years operators reported managing a given farm. Comparing characteristics of new farming operations with those that have existed for a longer period of time provides insights about some elements of the evolving structure of agricultural production in North Carolina. The total number of farms in North Carolina decreased more than 40 percent between 1974 and 1992. The rate of turnover in farming operations between 1987 and 1992 was not as great, however, as during the previous decade. Substantial variation in the rates of change in farm numbers and the ratios of entrants to exits among counties indicate that factors influencing the number and turnover in farming operations have not operated uniformly throughout the state. Regional differences in farm number changes and total acres of farmland indicate more consolidation of farming operations in the eastern part of North Carolina relative to other parts of the state. Much of the decrease in the number of farms in North Carolina has been concentrated among smaller farm size categories including those up to 220 acres in size. Nevertheless, nearly 60 percent of all new farms in North Carolina between 1978 and 1992 had less than 50 acres of farmland. Many new farms as well as those that have been in operation for longer periods of time appear to be part-time operations in that only a little over half of all farm operators in 1992 considered farming to be their principal occupation. An increasing proportion of farm operators, especially among those reporting farming as their principal occupation, are 65 years of age or older. This suggests increasing rates of management turnover in farming operations are likely. Considerably larger proportions of new farms, relative to farms that have been in operation for longer periods of time, are tenants. On the other hand, the largest proportion of continuing farming operations, especially among those with annual sales of farm products of $10,000 or more, were part owners. Consistent with the continuing shift in composition of agricultural production in the state; an increasing share of new and continuing farms in North Carolina are livestock oriented. Nevertheless more than 3300, or 42 percent of all farms that began operations between 1987 and 1992 had 50 percent or more of their total receipts from cash grain or other field crops.

T-duality in Massive Integrable Field Theories: The Homogeneous and Complex sine-Gordon Models
Creators: name: Miramontes, J. Luis
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The T-duality symmetries of a family of two-dimensional massive integrable field theories defined in terms of asymmetric gauged Wess-Zumino-Novikov-Witten actions modified by a potential are investigated. These theories are examples of massive non-linear sigma models and, in general, T-duality relates two different dual sigma models perturbed by the same potential. When the unperturbed theory is self-dual, the duality transformation relates two perturbations of the same sigma model involving different potentials. Examples of this type are provided by the Homogeneous sine-Gordon theories, associated with cosets of the form G/U(1)^r where G is a compact simple Lie group of rank r. They exhibit a duality transformation for each element of the Weyl group of G that relates two different phases of the model. On-shell, T-duality provides a map between the solutions to the equations of motion of the dual models that changes Noether soliton charges into topological ones. This map is carefully studied in the complex sine-Gordon model, where it motivates the construction of Bogomol'nyi-like bounds for the energy that provide a novel characterisation of the already known one-solitons solutions where their classical stability becomes explicit.

description: A weakly bound electron in a semiconductor quantum wire is shown to become entangled with an itinerant electron via the coulomb interaction. The degree of entanglement and its variation with energy of the injected electron, may be tuned by choice of spin and initial momentum. Full entanglement is achieved close to energies where there are spin-dependent resonances. Possible realisations of related device structures are discussed.
Collective diffusion coefficient of a charged colloidal dispersion: interferometric measurements in a drying drop

description: In the present work, we use Mach-Zehnder interferometry to thoroughly investigate the drying dynamics of a 2D confined drop of a charged colloidal dispersion. This technique makes it possible to measure the colloid concentration field during the drying of the drop at a high accuracy (about 0.5%) and with a high temporal and spatial resolution (about 1 frame/s and 5 $μ$m/pixel). These features allow us to probe mass transport of the charged dispersion in this out-of-equilibrium situation. In particular, our experiments provide the evidence that mass transport within the drop can be described by a purely diffusive process for some range of parameters for which the buoyancy-driven convection is negligible. We are then able to extract from these experiments the collective diffusion coefficient of the dispersion $D(φ)$ over a wide concentration range $φ=0.24$-$0.5$, i.e. from the liquid dispersed state to the solid glass regime, with a high accuracy. The measured values of $D(φ)\simeq 5$-$12 D_0$ are significantly larger than the simple estimate $D_0$ given by the Stokes-Einstein relation, thus highlighting the important role played by the colloidal interactions in such dispersions.

We show that within this model the up- and down-type Higgs mass soft supersymmetry breaking parameters have focus point behavior at the electroweak scale simultaneously when appropriate conditions are fulfilled. The focus point scenario is holding for large $\tan β$. This two focus point scenario allows to fix the pole top-quark mass which is within the experimentally allowed interval. The main goal of the present paper is the investigation of the influence of the existence of focus points on the determination of the mass of the lightest Higgs boson.

A free convection heat transfer correlation for very thin horizontal wires in rarefied atmospheres

description: Mars and upper Earth atmosphere missions are booming in recent years increasing the interest in heat transfer in rarefied gases. At these low pressures, the heat transfer problems involving small geometries whose characteristic length is of the order of the mean free path of the gas molecules, raises new difficulties. This being especially severe in the case of free convection, where the velocity of the gas is closely linked to the heat transfer problem. Experiments with horizontal wires with diameters of $12.7\ μ\mathrm{m}$ and $25\ μ\mathrm{m}$ were conducted in a tailored vacuum chamber with pressures from $0.03$ milibar to ambient pressure, reaching temperature differences of up to $80$ K between the wire and the air. Experimental data is comprised of Rayleigh numbers from $10^{-13}$ to $10^{-5}$ that cover a wide range from free molecular flow to continuum regime. Particularly for the transition regime, with Knudsen numbers ranging between 0.1 and 10, the experimental data shows that the free convection heat transfer cannot be represented solely as a function of the Rayleigh number, but a dependence on Knudsen number must be introduced into the correlation as well. The presented results for the Nusselt number below Rayleigh numbers of $10^{-8}$ exhibit a clear departure from the available correlations in the literature. A new empirical correlation for free convection from horizontal thin wires from the transition to continuum regime is presented. The present work sheds light on current thermal engineering problems which involves very thin wires in their systems which interact with a surrounding environment with a significant level of rarefaction.

At small frequencies of motion the scattered light spectrum reveals the frequency shift that is governed by the Doppler effect. At higher motion frequencies, the scattered light spectra acquire sidebands stemming from the Raman effect. We investigate the crossover between these two regimes and propose a realistic quantum well structure for its observation.

description: In math.QA/0311303 B. Feigin, G. Felder, and B. Shoikhet proposed an explicit formula for the trace density map from the quantum algebra of functions on an arbitrary symplectic manifold M to the top degree cohomology of M. They also evaluated this map on the trivial element of K-theory of the algebra of quantum functions. In our paper we evaluate the map on an arbitrary element of K-theory, and show that the result is expressed in terms of the A-genus of M, the Deligne-Fedosov class of the quantum algebra, and the Chern character of the principal symbol of the element. For a smooth (real) symplectic manifold (without a boundary), this result implies the Fedosov-Nest-Tsygan algebraic index theorem.

description: We study the transition from incoherence to coherence in large networks of coupled phase oscillators. We present various approximations that describe the behavior of an appropriately defined order parameter past the transition, and generalize recent results for the critical coupling strength. We find that, under appropriate conditions, the coupling strength at which the transition occurs is determined by the largest eigenvalue of the adjacency matrix. We show how, with an additional assumption, a mean field approximation recently proposed is recovered from our results. We test our theory with numerical simulations, and find that it describes the transition when our assumptions are satisfied. We find that our theory describes the transition well in situations in which the mean field approximation fails. We study the finite size effects caused by nodes with small degree and find that they cause the critical coupling strength to increase.

description: In textbooks of geophysical fluid dynamics, the Coriolis force and the centrifugal force in a rotating fluid system are derived by making use of the fluid parcel concept. In contrast to this intuitive derivation to the apparent forces, more rigorous derivation would be useful not only for the pedagogical purpose, but also for the applications to other kinds of rotating geophysical systems rather than the fluid. The purpose of this paper is to show a general procedure to derive the transformed equations in the rotating frame of reference based on the local Galilean transformation and rotational coordinate transformation of field quantities. The generality and usefulness of this Eulerian approach is demonstrated in the derivation of apparent forces in rotating fluids as well as the transformed electromagnetic field equation in the rotating system.

description: A new approach to produce optimal porous mesostructures and at the same time optimizing the macro structure subject to a compliance cost functional is presented. It is based on a phase-field formulation of topology optimization and uses a local volume constraint (LVC). The main novelty is that the radius of the LVC may depend both on space and a local stress measure. This allows for creating optimal topologies with heterogeneous mesostructures enforcing any desired spatial grading and accommodating stress concentrations by stress dependent pore size. The resulting optimal control problem is analysed mathematically, numerical results show its versatility in creating optimal macroscopic designs with tailored mesostructures.

description: In the AdS/CFT correspondence, a dynamical cosmological constant $Λ$ in the bulk corresponds to varying the number of colors $N$ in the boundary gauge theory with a chemical potential $μ$ as its thermodynamic conjugate. In this work, within the context of Schwarzschild black holes in $AdS_5 \times S^5$ and its dual finite temperature $\mathcal{N}=4$ superconformal Yang-Mills theory at large $N$, we investigate thermodynamic geometry through the behavior of the Ruppeiner scalar $R$. The sign of $R$ is an empirical indicator of the nature of microscopic interactions and is found to be negative for the large black hole branch implying that its thermodynamic characteristics bear qualitative similarities with that of an attraction dominated system, such as an ideal gas of bosons. We find that as the system's fugacity approaches unity, $R$ takes increasingly negative values signifying long range correlations and strong quantum fluctuations signaling the onset of Bose condensation. On the other hand, $R$ for the small black hole branch is negative at low temperatures and positive at high temperatures with a second order critical point which roughly separates the two regions.

description: We introduce a general scheme to realize perfect storage of quantum information in systems of interacting qubits. This novel approach is based on {\it global} external controls of the Hamiltonian, that yield time-periodic inversions in the dynamical evolution, allowing a perfect periodic quantum state recontruction. We illustrate the method in the particularly interesting and simple case of spin systems affected by XY residual interactions with or without static imperfections. The global control is achieved by step time-inversions of an overall topological phase of the Aharonov-Bohm type. Such a scheme holds both at finite size and in the thermodynamic limit, thus enabling the massive storage of arbitrarily large numbers of local states, and is stable against several realistic sources of noise and imperfections.

description: We investigate the full U(3)$\otimes$U(3) chiral symmetry restoration, at finite temperature and density, on the basis of a quark model which incorporates the most relevant properties of QCD in this context: explicit and spontaneous breaking of chiral symmetry and axial U$_A$(1) symmetry breaking. A specific lattice-inspired behavior of the topological susceptibility, combined with the convergence of chiral partners, signals the onset of an effective chiral symmetry restoration. The results suggest that the axial part of the symmetry is restored before the possible restoration of the full U(3)$\otimes$U(3) chiral symmetry can occur. This conclusion is valid in the context of both finite temperature and density.

description: Genes of the major histocompatibility complex (MHC) play a key role in the adaptive immunity of vertebrates, as they encode receptors responsible for antigen recognition. Evolutionary history of the MHC proceeded through numerous gene duplications, which increase the spectrum of pathogens recognized by individuals. Although pathogen-mediated selection is believed to be a primary driver of MHC expansion over evolutionary times, empirical evidence for this association is virtually lacking. Here, we used an extensive dataset on MHC class II copy number variation in non-passerine birds to test for an evolutionary correlation with helminth parasite richness. As expected, our phylogenetically-informed modelling revealed a positive association between MHC copy number and total helminth richness, even after controlling for a broad spectrum of ecological and life-history traits. Thus, total helminth richness appears to be the most important correlate of MHC copy number, supporting a leading role of pathogen-mediated selection in the evolution of MHC in birds. Our results provide some of the first, although correlative, evidence linking parasitism to interspecific variation in MHC copy number among birds.

description: Pollution of the environment by metals and organic contaminants is an intractable global problem, with cleanup costs running into billions of dollars using current engineering technologies. The availability of alternative, cheap and effective technologies would significantly improve the prospects of cleaning-up metal contaminated sites. Phytoremediation has been proposed as an economical and ‘green’ method of exploiting plants to extract or degrade the contaminants in the soil. To date, the majority of phytoremediation efforts have been directed at leaping the biological, biochemical and agronomic hurdles to deliver a working technology, with scant attention to the economic outlook other than simple estimates of the cost advantages of phytoremediation over other techniques. In this paper we use a deterministic actuarial model to show that uncertainty in project success (the possibility that full clean up may not be realized) may significantly increase the perceived costs of remediation works for decision-makers.

description: It was recently shown that quantum annealing can be used as an effective, fast subroutine in certain types of matrix factorization algorithms. The quantum annealing algorithm performed best for quick, approximate answers, but performance rapidly plateaued. In this paper, we utilize reverse annealing instead of forward annealing in the quantum annealing subroutine for nonnegative/binary matrix factorization problems. After an initial global search with forward annealing, reverse annealing performs a series of local searches that refine existing solutions. The combination of forward and reverse annealing significantly improves performance compared to forward annealing alone for all but the shortest run times.

description: Phytoremediation is the use of living plants, known as hyperaccumulators which absorb unusually large amounts of metals in comparison to other plants. The use of classical plant breeding and new molecular techniques offers great potential to develop crops with the ability to clean up polluted sites. While these technologies have gained widespread attention, prior to commercial development, there are risks that must be considered – only a few of which have received even modest examination. Therefore, the focus of this working paper is to explore specific risks associated with phytoremediation and suggest ways in which these risks can be managed so that new, novel, and innovative plant technologies may be applied to provide low cost and efficient environmental solutions.
