description: This paper explores the emerging concept of place-based economic policy. It reviews recent literature on place-based economics policy, especially regional competitiveness policy, and explores the adoption and diffusion of this concept by economic development practitioners and social science researchers. It attempts to answer the question: Are place-based economic policy and the underlying conceptual foundations lasting innovations, or are they fads which economic development practitioners and social scientists will adopt until another fad emerges? The conclusion is that economic development practitioners and social scientists do tend to respond to fads. To ensure that regional economic development policy is not dominated by fads, social scientists must get out in front of economic development practitioners far enough to thoroughly develop and test regional competitiveness and other place-based economic theories.

description: When a parameter quench is performed in an isolated quantum system with a complete set of constants of motion, its out of equilibrium dynamics is considered to be well captured by the Generalized Gibbs Ensemble (GGE), characterized by a set $\{λ_α\}$ of coefficients related to the constants of motion. We determine the most elementary GGE deviation from the equilibrium distribution that leads to detectable effects. By quenching a suitable local attractive potential in a one-dimensional electron system, the resulting GGE differs from equilibrium by only one single $λ_α$, corresponding to the emergence of an only partially occupied bound state lying below a fully occupied continuum of states. The effect is shown to induce optical gain, i.e., a negative peak in the absorption spectrum, indicating the stimulated emission of radiation, enabling one to identify GGE signatures in fermionic systems through optical measurements. We discuss the implementation in realistic setups.

description: We study the massive point-vortex model introduced in Ref. [Phys. Rev. A 101, 013630 (2020)], which describes two-dimensional point vortices of one species that have small cores of a different species. We derive the relevant Lagrangian itself, based on the time-dependent variational method with a two-component Gross-Pitaevskii (GP) trial function. The resulting Lagrangian resembles that of charged particles in a static electromagnetic field, where the canonical momentum includes an electromagnetic term. The simplest example is a single vortex with a rigid circular boundary, where a massless vortex can only precess uniformly. In contrast, the presence of a sufficiently large filled vortex core renders such precession unstable. A small core mass can also lead to small radial oscillations, which are, in turn, clear evidence of the associated inertial effect. Detailed numerical analysis of coupled two-component GP equations with a single vortex and small second-component core confirms the presence of such radial oscillations, implying that this more realistic GP vortex also acts as if it has a small massive core.

description: Neutral intergalactic clouds are so greatly out numbered by galaxies that their integral HI content is negligible in comparison to that contained in optically luminous galaxies. In fact, no HI cloud that is not associated with a galaxy or grouping of galaxies has yet been identified. This points to a causal relationship that relies on gravitational potentials that bind galaxies also being responsible for confining HI clouds to sufficient density that they can become self-shielding to the ionizing background radiation. Unconfined clouds of low density become ionized, but confined clouds find themselves vulnerable to instability and collapse, leading to star formation.

description: In this study we attempt to understand the relationship between regional growth in population, employment, and per capita income, and farmland development in Maryland, Pennsylvania, and West Virginia. A spatial simultaneous equations model is estimated using county-level data. Results indicate that while county income growth and agricultural land value increases in neighboring counties increase the rate of farmland loss, growth in county agricultural land values, increases in agricultural land density in neighboring counties, and increases in agricultural income per farm reduce farmland losses. Farmland protection policies were not significant in reducing agricultural land development. This approach, focused on regional growth, provides insight into linkages between growth and agricultural land development that can potentially enhance land use planning.

description: This paper addresses the possibility that competitive rural manufacturing is increasingly driven by quality-of-life factors required to attract highly skilled and creative workers. Recent findings that highly creative workers are drawn to amenity-rich rural areas provide the empirical leverage for testing anecdotal claims that these areas tend to contain small manufacturing bases that are more reliant on innovation. This contrasts with the cost advantage rationale of traditional rural manufacturing, an advantage that is eroding with increased globalization. The analysis provides the first empirical evidence that the start of entrepreneurial manufacturing plants and the adoption of advanced technologies and management practices are strongly associated with the local employment share in highly creative occupations.

description: Semiconducting skutterudite CeFe$_4$P$_{12}$ is investigated by synchrotron x-ray photoemission spectroscopy (PES) and x-ray absorption spectroscopy (XAS). Ce 3$d$ core-level PES and 3$d-4f$ XAS, in combination with single impurity Anderson model (SIAM) calculations, confirm features due to $f^0$, $f^1$ and $f^2$ configurations. The Ce 4$f$ density of states (DOS) indicates absence of a Kondo resonance at Fermi level, but can still be explained by SIAM with a small gap in non-$f$ DOS. While Ce 4$f$ partial DOS from band structure calculations are also consistent with the main Ce 4$f$ DOS, the importance of SIAM for core and valence spectra indicates Kondo semiconducting mixed valence for CeFe$_4$P$_{12}$, derived from strong hybridization between non-$f$ conduction and Ce 4$f$ DOS.

description: This study uses locally weighted regression to identify county-level characteristics that serve as drivers of creative employment throughout the southern United States. We found that higher per capita income, greater infrastructure investments, and the rural nature of a county tended to promote creative employment density, while higher scores on a natural amenity index had the opposite effect. We were also able to identify and map clusters of rural counties where the marginal effects of these variables on creative employment density were greatest. These findings should help rural communities to promote creative employment growth as a means of furthering rural economic development.

description: A key challenge in scaling quantum computers is the calibration and control of multiple qubits. In solid-state quantum dots, the gate voltages required to stabilize quantized charges are unique for each individual qubit, resulting in a high-dimensional control parameter space that must be tuned automatically. Machine learning techniques are capable of processing high-dimensional data - provided that an appropriate training set is available - and have been successfully used for autotuning in the past. In this paper, we develop extremely small feed-forward neural networks that can be used to detect charge-state transitions in quantum dot stability diagrams. We demonstrate that these neural networks can be trained on synthetic data produced by computer simulations, and robustly transferred to the task of tuning an experimental device into a desired charge state. The neural networks required for this task are sufficiently small as to enable an implementation in existing memristor crossbar arrays in the near future. This opens up the possibility of miniaturizing powerful control elements on low-power hardware, a significant step towards on-chip autotuning in future quantum dot computers.

description: Using a system composed of a Quadrupole and Ioffe Configuration (QUIC) trap loaded from a slowed atomic beam, we have performed experiments to observe the Bose-Einstein Condensation of Na atoms. In order to obtain the atomic distribution in the trap, we use an in situ out of resonance absorption image through a probe beam, to determine temperature and density. The phase space density (D) is calculated using the density profile and the temperature. We have followed D as a function of the final evaporation frequency. The results show that at 1.65 MHz we crossed the value for D expected to correspond to the critical point to start de Bose-Condensation of the sample. Due to the low number of atoms remaining in the trap at the critical point, the interaction produces minor effects and therefore an ideal gas model explains well the observations. We analyze the obtained low number in terms of efficiency of evaporation. The utility of an in situ detection is illustrated by measuring the harmonic gas pressure of the trapped gas in the route to condensation.

Maya seats and Maya seats-of-authority
Creators: name: Noble, Sandra Eleanor
Publisher: name: University of British Columbia
Year: 2009

description: Interpretation of Maya social organization through material remains has long been a subject of speculation. The gap between data and interpretation inevitably involves the concerns and conditions of the society producing such interpretive discourse, and diverging interests and modes of analysis continue to result in alternative and often conflicting interpretations of ancient Maya society, often involving suppositions of systemic weakness that led to the collapse of its centralized or dynastic authorities in the ninth century. Currently central in such interpretations is the role of inscribed stone seats, erected by "subsidiary" or non-royal members of Maya society in "subsidiary" districts or suburbs of the major Maya polity of Copan. At issue are the problematic interpretations of these seats that have been constructed to support a particular construct of Maya sociopolitical organization and an inherent weakness that would have doomed it to collapse. This thesis explains the premises of this current interpretation and examines the Copan seats from several alternate viewpoints and methodologies. Formulation of a comprehensive dataset of actual Maya seats and representations of seats in sculpture, ceramic, and hieroglyphic contexts demonstrates that the Copan seats fit comfortably within Maya epigraphic, stylistic and iconographic conventions rather than representing a revolutionary challenge to dynastic authority. Through analyses of form and construction, locational context, varieties of decoration, and content of inscriptions, this thesis shows that such hierarchically-privileged seats-of-authority, which are found in residential complexes of very different socio-economic status, not only in Copan but throughout the Maya region in Classic times, better support a model of factional competition than of autocratic dynastic authority. These seats appear to have been designed to construct the social position of their occupants in relation to subordinate members of their own factions, to other faction leaders with whom they were in competition, and to the ruler as both head of the polity and leader of the royal faction. Indeed, discursive notions of the seat and seating were central to ancient Maya concepts of patriarchal authority. Further, since such factional competition may be shown to characterize Maya social organization since Late Pre-Classic times, the inscribed Copan seats provide no insights as to the causes of the so-called "Maya Collapse."
A Consumption Base Theory of Development: An Application to the Rural Cultural Economy

description: Export base theory, which posits that overall regional growth is a function of external sales of locally produced goods and services, dominates economic development practice. But the consumption base can also serve as a growth driver, especially in small towns and rural areas. Local investments may induce residents to divert expenditures into local purchases, attract new and footloose residents and tourists, and revitalize aging town centers. A consumption base approach is not reducible to import substitution, but seeks to serve latent demand and alter the broad portfolio of goods and services purchased locally. I present the analytics for a consumption base theory and demonstrate how cultural investments prompt regional growth, emphasizing the role of artists as catalysts. Three types of arts and cultural investments are explored: artists' centers, artists' live/work spaces, and performing arts facilities, with examples from rural and small town settings. I conclude with rural cultural strategy recommendations.

description: Over the last decade of machine learning, convolutional neural networks have been the most striking successes for feature extraction of rich sensory and high-dimensional data. While learning data representations via convolutions is already well studied and efficiently implemented in various deep learning libraries, one often faces limited memory capacity and insufficient number of training data, especially for high-dimensional and large-scale tasks. To overcome these limitations, we introduce a network architecture using a self-adjusting and data dependent version of the Radon-transform (linear data projection), also known as x-ray projection, to enable feature extraction via convolutions in lower-dimensional space. The resulting framework, named PiNet, can be trained end-to-end and shows promising performance on volumetric segmentation tasks. We test proposed model on public datasets to show that our approach achieves comparable results only using fractional amount of parameters. Investigation of memory usage and processing time confirms PiNet's superior efficiency compared to other segmentation models.

We find plausible scenarios for the production of dark-photon dark matter of mass in a wide range, as low as a micro-electron volt to $10^{14}$ GeV. Gravitational particle production does not depend on any coupling of the dark photon to standard-model particles.

description: While historians believe that preserving a historic building in its original location is important to maintain its historic integrity, the general public's opinion is unknown. Survey data were gathered from local residents regarding a proposed relocation of a historic mill in rural West Virginia. Only a minority of the sample population supported preserving the mill at its original location. Willingness to pay for preservation was estimated at $8.45 for a one-time donation for the sample and $2.29 after adjusting for non-respondents using characteristics of the local population.

description: Distinguishing physical processes is one of the fundamental problems in quantum physics. Although distinguishability of quantum preparations and quantum channels have been studied considerably, distinguishability of quantum measurements remains largely unexplored. We investigate the problem of single-shot discrimination of quantum measurements using two strategies, one based on single quantum systems and the other one based on entangled quantum systems. First, we formally define both scenarios. We then construct sets of measurements (including non-projective) in arbitrary finite dimensions that are perfectly distinguishable within the second scenario using quantum entanglement, while not in the one based on single quantum systems. Furthermore, we show that any advantage in measurement discrimination tasks over single systems is a demonstration of Einstein-Podolsky-Rosen 'quantum steering'. Alongside, we prove that all pure two-qubit entangled states provide an advantage in a measurement discrimination task over one-qubit systems.

description: It is important to better understand why in Mozambique, a land abundant country by Sub-Saharan Africa countries standards, there are seemingly many land-poor households. In Mozambique, recent studies show that land plays a key role in generating income for rural households, and those with less land tend to be poor. Thus, the present study was intended to further confirm the existence of land-and income-poor households, to understand the nature and evolution of this group and to clarify the factors that are leading to its creation. Data from 521 rural households across the cotton belt in Northern Mozambique and from the Ministry of Agriculture 1996 National Smallholder Survey were used. Additional data collection consisted of in-depth case studies in selected villages of Nampula and Cabo Delgado Provinces, and field area measurements in these locations. This study has confirmed the existence of a significant group of land- and income-poor households in Northern Mozambique. Results also showed that land inequality throughout the country is similar to that found in Nampula and Cabo Delgado, and this inequality has changed little three years after the ending of the war. Analysis of the relationship between land holdings and household income showed that the observed inequality in land distribution is a problem, in that land holdings are a major determinant of household income. Thus, land poor households face both a serious income shortage and, in all likelihood, a critical food security problem. Results show that understanding the way the customary tenure system and related traditional decision making structures operate within the society is important to better understand why some smallholders are land-poor. Findings indicate that there is an effect on land access of local social hierarchy. In the Macua society specifically, findings suggest that there is an effect of local social hierarchy on land access. The role of the principal Atata was shown to be especially important in the Nampula villages. It was shown that the size of Matala under the control each of principal Atata varies greatly in these villages; that per capita land availability within these Matala also varies greatly; and that households in small Matala are only slightly more likely to possess fields outside their Matala than households in large Matalas. We, therefore, hypothesize that the size of Matala is a key determinant of total land availability at the household level, and suggest focusing further research efforts on this issue.

description: Combustion synthesis is used to prepare thin UO2 films on aluminum alloy substrates. This simple preparation method involves electrospraying uranyl nitrate + acetylacetone + 2-methoxyethanol solution on the substrate, followed by a short annealing at 350 or 550 °C. The irradiation of films with a 40Ar2+ ion beam (energy of 1.7 MeV and fluences of 7.7 × 1016 and 1.3 × 1017 ions/cm2) is conducted to investigate irradiation-induced restructuring processes. High-resolution transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) investigations show that the annealing temperature significantly influences the crystallinity and stability of materials during irradiation. A small amount of Mg in the alloy substrate diffuses into the amorphous Al2O3 interfacial layer between the film and the substrate. Local thermal spikes from the incoming ions facilitate the irradiation-induced mixing of immiscible Al2O3 and UO2 for the materials prepared at 350 °C. This mass diffusion produces relatively large cavities at the interface. Selective diffusion of a more significant amount of Mg for the materials prepared at 550 °C suppresses the mixing of the Al2O3 interlayer with the film but forms MgyU1–yO2±x solid solutions during irradiation. Local thermal heating triggers the precipitation of a discontinuous crystalline MgO layer close to the film surface. The enhanced and selective diffusion of Mg into the film makes the materials prepared at 550 °C more robust and mechanically stable than those prepared at 350 °C.

description: We suggest an interpretation of mirror symmetry for toric varieties via an equivalence of two conformal field theories. The first theory is the twisted sigma model of a toric variety in the infinite volume limit (the A-model). The second theory is an intermediate model, which we call the I-model. The equivalence between the A-model and the I-model is achieved by realizing the former as a deformation of a linear sigma model with a complex torus as the target and then applying to it a version of the T-duality. On the other hand, the I-model is closely related to the twisted Landau-Ginzburg model (the B-model) that is mirror dual to the A-model. Thus, the mirror symmetry is realized in two steps, via the I-model. In particular, we obtain a natural interpretation of the superpotential of the Landau-Ginzburg model as the sum of terms corresponding to the components of a divisor in the toric variety. We also relate the cohomology of the supercharges of the I-model to the chiral de Rham complex and the quantum cohomology of the underlying toric variety.

description: We show how one can deterministically generate photonic matrix product states with high bond and physical dimensions with an atomic array if one has access to a Rydberg-blockade mechanism. We develop both a quantum gate and an optimal control approach to universally control the system and analyze the photon retrieval efficiency of atomic arrays. Comprehensive modeling of the system shows that our scheme is capable of generating a large number of entangled photons. We further develop a multi-port photon emission approach that can efficiently distribute entangled photons into free space in several directions, which can become a useful tool in future quantum networks.

description: The evaluation of USAID funded farming systems research projects must play an important role in the design of future projects if one is to build on past experience to improve project performance. The development of an institutional memory is particularly important as FSR is new and still taking shape. Based on a comparison of four mid-term evaluations of FSR projects and a review of an Agency funded study, it appears that evaluations are not contributing all that they might to increasing the knowledge base. Frequently, crucial implementation issues are not covered and information is presented in a confusing and inaccessible format. This study outlines the role of evaluation in USAID, analyses four mid-term evaluations and proposes a list of questions to be addressed by evaluation teams. These questions address key issues related to project design and implementation. The proposed questions could improve future project performance by increasing the Agency's understanding of its past experiences with FSR projects.
Supersymmetry breaking and the radion in AdS_4 brane-worlds

description: We compute the one-loop correction to the radion potential in the Randall-Sundrum model with detuned brane tensions, with supersymmetry broken by boundary conditions. We concentrate on the small-warping limit, where the one-loop correction is significant. With pure supergravity, the correction is negative, but with bulk hypermultiplets, the correction can be positive, so that the 4d curvature can be lowered, with the radion stable. We use both the KK theory, and the 4d radion effective theory for this study.

Statistical continuum modeling of mass transport through fractured media, in two and three dimensions
Creators: name: Parney, Robert Wyn
Publisher: name: University of British Columbia
Year: 2009

description: The Statistical Continuum Method (SCM) provides a technique to model aqueous phase transport through a fractured rock mass at the field scale, while explicitly including the effects on transport of fracturing that are observed on the scale of a borehole or outcrop. The SCM approach models mass transport in two stages: (1) particles are first "educated" in a subdomain consisting of multiple discrete networks in order to capture the range of motion possible within a fracture system; and (2) particles are then moved in a random-walk through a larger continuum, obeying the range of motion "learned" within the subdomain. The use of discrete networks allows particle movements in the SCM continuum to honor the particle motion that occurs in the discrete subdomain, without the fundamental changes in the nature of the transport process necessary in most continuum approximations. The use of the continuum permits these movements to be extended into domains significantly larger or more complex than those that can be modeled by conventional discrete network simulations. The key element in the SCM method is the determination of the most appropriate methods for translating the motion of particles in the discrete subdomain into a set of statistical distributions that are then sampled in the continuum. To evaluate the effectiveness of the SCM approach the evolution of spatial moments through time for SCM models are compared with the evolution of moments for equivalent discrete network models. The SCM method is capable of reproducing mass transport in two and three-dimensional discrete fracture networks, as evidenced by the match between the trends in spatial moments through time for the discrete network and the spatial moments for the SCM model. A number of SCM modeling approaches produce moment values within one standard deviation of the average of the network realizations, although no one model works best for all fracture systems.
IMPLEMENTATION AND EVALUATION OF RURAL DEVELOPMENT PROJECTS UNDER UNCERTAINTY: WITH A SPECIAL REFERENCE TO THE SEDHIOU II PROJECT

description: This paper is centered around rural development projects. But what is meant, specifically, by development? There is a tendency for people to confuse development with economic development and to use national income as a yardstick for measuring economic development. Economic development is too narrow a concept to tell all the development story. There are policital and social dimensions to development. Any definition of development incorporates implicitly or explicitly some value judgements. But where are those value judgements to come from? The common answer is that they should come from governments through their planning documents or the development path of other countries whose present state is judged desirable. A definition of development is basically a political statement. But what are the basic needs all development strategies are intended to satisfy? One answer is obvious, enough food, which is related to the satisfaction of a basic human biological need. Without enough food it is difficult for a human being to fully use her body and her mind. Enough income is a necessary but not sufficient condition for good nutrition as pointed out by Pinstrup-Anderson. Another basic need is a lucrative occupation for people to earn their livelihood and to be able to satisfy their own needs without resting upon outside assistance. Income distribution is another important aspect of development. A country relates its wealth to other countries wealth as do most human beings. The way income is distributed explains the gap between the average income per capita, in a country, and the proportion of the population living in poverty. Other considerations are education, freedom of speech and citizenship of a truly independent nation. But to promote those and other development objectives, plans, programs, and projects have an important role to play.
Non-radiating and radiating configurations driven by left-handed metamaterials

description: It is shown that a pair of identical emitters (e.g. wire dipole antennas) in the focal points of a disc, made of left-handed metamaterial (a "perfect" lens), form a non-radiating electromagnetic configuration. The emitters are fed with voltages of equal magnitude and pi-out-of-phase. Detailed finite-difference time-domain (FDTD) modeling shows that there are non-propagating electromagnetic fields generated - fields that remain confined within the region between the emitters and the lens. The energy balance of the system shows that the radiation resistance of the system is very low. This means that the input power is converted to heat in the volume of the lens and only a small fraction of it is radiated. The system performance shows that disturbing the configuration of the non-propagating electromagnetic fields with the presence of an externally introduced object stimulates radiation. This suggests possible detector applications. In-phase feeding voltages are also studied with the consequence that the radiation resistance of the antennae is increased.

Life in Elliptical Galaxies: Hot Spheroids, Fast Stars, Deadly Comets?

description: Elliptical galaxies have dynamically hot ($σ_{1D}$ ~ 100 -- 300 km s$^{-1}$) populations of stars, and presumably, smaller objects like comets. Because interstellar minor bodies are moving much faster, they hit planets harder and more often than in the local Galaxy. I estimate the rates for Chicxulub-scale impacts on an Earth-size planet in elliptical galaxies as a potential habitability constraint on intelligent life. Around most stars in a normal elliptical galaxy, these planets receive only ~0.01 -- 0.1 Gyr$^{-1}$, although hazardous rates may be common in certain compact early-type galaxies and red nuggets. About 5% of the stellar mass is in a region where the rate is >10 Gyr$^{-1}$, large enough to dominate the mass extinction rate. This suggests that elliptical galaxies have an exclusion zone of order one hundred parsecs in radius around their centers for the evolution of intelligent life.

Field dependence of the Yukawa coupling in the three flavor quark-meson model

description: We investigate the renormalization group flow of the field-dependent Yukawa coupling in the framework of the three flavor quark-meson model. In a conventional perturbative calculation, given that the field rescaling is trivial, the Yukawa coupling does not get renormalized at the one-loop level if it is coupled to an equal number of scalar and pseudoscalar fields. Its field-dependent version, however, does flow with respect to the scale. Using the functional renormalization group technique, we show that it is highly nontrivial how to extract the actual flow of the Yukawa coupling as there are several new chirally invariant operators that get generated by quantum fluctuations in the effective action, which need to be distinguished from that of the Yukawa interaction.

Stability of large-amplitude viscous shock under periodic perturbation for 1-d isentropic Navier-Stokes equations

description: The stability of solutions under periodic perturbations for both inviscid and viscous conservation laws is an interesting and important problem. In this paper, a large-amplitude viscous shock under space-periodic perturbation for the isentropic Navier-Stokes equations is considered. It is shown that if the initial perturbation around the shock is suitably small and satisfies a zero-mass type condition (2.17), then the solution of the N-S equations tends to the viscous shock with a shift, which is partially determined by the periodic oscillations. In other words, the viscous shock is nonlinearly stable even though the perturbation oscillates at the far fields. The key point is to construct a suitable ansatz $ (\tilde{v},\tilde{u}) $, which carries the same oscillations of the solution $ (v,u) $ at the far fields, so that the difference $ (v-\tilde{v},u-\tilde{u}) $ belongs to the $ H^2(R) $ space for all $ t\geq 0. $
