description: This dissertation discusses the nature of international cooperation and domestic politics in climate change policy. More specifically, it examines whether and how democratic countries perform better in reducing carbon emissions. By employing a cross-national time-series analysis using bothaggregate and disaggregate measures of domestic institutional traits of democracy for 97 countries, I find that aggregate measures are inadequate in studying climate change policy. Instead, the findings suggest that civil liberties play an important role when considering how countries perform better at lowering per capita carbon dioxide emissions. This study also finds that highlydemocratic countries with a well-educated citizenry are more likely to reduce carbon emissions compared to other countries. These findings have implications on empirical studies in climate change politics as well as how various spheres of domestic politics interact in the climate change arena. In summary, this paper highlights the causal mechanisms of specific institutional traits of democracy in reducing carbon emissions using quantitative methodsand fills an important gap in the climate change politics literature, where previous studies have found conflicting evidence on the effects of democracy and democratic institutions on climate change policy.

description: As multiple countries share a river, the likelihood of a water resource conflict from climate change could be higher between countries. In this paper, we demonstrate how countries can cooperate in transboundary water sharing in a sustainable way, given the impacts of climate change. We illustrate the case of water sharing of the Volta River between the upstream and downstream country, Burkina Faso and Ghana respectively, where the latter country faces a tradeoff of water use between agriculture in the north and production of hydro energy in the south. In the framework of a stochastic Stackelberg differential game, we have shown how the issue of water sharing could be linked to hydropower export that can make water sharing between the countries sustaining in the event of climate change. Our results indicate that during cooperation, Ghana will have an opportunity to increase its water abstraction for agriculture, which has remained largely restricted. We also find that the equilibrium strategies in the long run steady state distribution are stable even with increasing variances of water flow.

Analysis of piezoelectric cylindrical actuators and 1-3 piezocomposite unit cells
Creators: name: Chen, Yue
Publisher: name: University of British Columbia
Year: 2009

description: Adaptive structures incorporated with sensors and actuators are increasingly used in many engineering applications. Actuators used in adaptive structures are made out of piezoelectric ceramics, shape memory alloys (SMA), electrorheological fluids (ER fluids) or magnetostrictive materials. Among the many types of piezoelectric actuator elements, the cylindrical shape is widely used in practical applications involving fuel injectors, atomic force microscopes, high-precision telescopes, etc. In addition, the piezoelectric phase of piezocomposites is made out of cylindrical rods or fibers. Piezoelectric materials are very brittle and stress/electric field concentration at electrodes and other discontinuities often contribute to mechanical or dielectric breakdown. The study of electromechanical field of a cylindrical piezoelectric element and a composite unit cell with a piezoceramic core surrounded by a polymeric shell is therefore important to the understanding of failure of cylindrical actuators and design of piezocomposites for maximum electromechanical coupling. This thesis presents a comprehensive theoretical study of homogeneous piezoelectric cylinders and a unit cell of 1-3 piezocomposites. The governing equations for coupled axisymmetric electroelastic field in a transversely isotropic piezoelectric medium are established in terms of the displacements and electric potential. The general solutions of the governing equations are obtained in terms of a series of Bessel functions of the first and second kind. Several boundary-value problems are solved, and a computer code is developed to compute the electroelastic field in solid and annular cylinders for different aspect ratios, electromechanical loading and material properties. The salient features of the electroelastic field are identified. The effective properties of a 1-3 piezocomposite are studied under hydrostatic loading for different fiber volume fractions and polymer and ceramic properties. Optimum fiber volume fractions for maximum electromechanical coupling are determined for different ceramic-polymer combinations.

description: Spin state detection is a key but very challenging step for any spin-based solid-state quantum computing technology. In fullerene based quantum computer technologies, we here propose to detect the single spin inside a fullerene by transferring the quantum information from the endohedral spin to the ground states of a molecular nanomagnet Fe$_{8}$, with large spin S=10. We show how to perform the required SWAP operation and how to read out the information through state-of-the-art techniques such as micro-SQUID.

On homogenization of electromagnetic crystals formed by uniaxial resonant scatterers

description: Dispersion properties of electromagnetic crystals formed by small uniaxial resonant scatterers (magnetic or electric) are studied using the local field approach. The goal of the study is to determine the conditions under which the homogenization of such crystals can be made. Therefore the consideration is limited by the frequency region where the wavelength in the host medium is larger than the lattice periods. It is demonstrated that together with known restriction for the homogenization related with the large values of the material parameters there is an additional restriction related with their small absolute values. From the other hand, the homogenization becomes allowed in both cases of large and small material parameters for special directions of propagation. Two unusual effects inherent to the crystals under consideration are revealed: flat isofrequency contour which allows subwavelength imaging using canalization regime and birefringence of extraordinary modes which can be used for beam splitting.

description: We investigate the relationship between black hole accretion and star formation in a sample of 453 $z\approx0.3$ type 1 active galactic nuclei (AGNs). We use available CO observations to demonstrate that the combination of nebular dust extinction and metallicity provides reliable estimates of the molecular gas mass even for the host galaxies of type 1 AGNs. Consistent with other similar but significantly smaller samples, we reaffirm the notion that powerful AGNs have comparable gas content as nearby star-forming galaxies and that AGN feedback does not deplete the host of cold gas instantaneously. We demonstrate that while the strong correlation between star formation rate and black hole accretion rate is in part driven by the mutual dependence of these parameters on molecular gas mass, the star formation rate and black hole accretion rate are still weakly correlated after removing the dependence of star formation rate on molecular gas mass. This, together with a positive correlation between star formation efficiency and black hole accretion rate, may be interpreted as evidence for positive AGN feedback.

description: One of the impacts of higher prices along with greater volatility in futures and basis is that there is pressure for an escalation in cash contracting for grain. This volatility has resulted in an unprecedented level of contracting with growers in recent years. There is a wide array of cash contracts with varying terms. There is also a growing realization of growers not delivering on contracts, in part due to escalation in postcontract prices. These are evolving as major strategic issues for buyers and the marketing system, particularly as buyers seek to use such contracting strategies as an element of risk mitigation. There are three purposes of this article. First is to provide a broad survey of contract terms used in grain contracting with growers. Second, we illustrate some issues in contracting of some of the grains (durum, malting barley) in the upper Midwest. Third, we show some of the common contract clauses being adapted in these contracts. Finally, we summarize these issues with respect to industry implications.

description: It is commonly asserted that speculative buying by index funds in commodity futures and over–the–counter derivatives markets created a ‘‘bubble’’ in commodity prices, with the result that prices, and crude oil prices, in particular, far exceeded fundamental values at the peak. The purpose of this paper is to show that the bubble argument simply does not withstand close scrutiny. Four main points are explored. First, the arguments of bubble proponents are conceptually flawed and reflect fundamental and basic misunderstandings of how commodity futures markets actually work. Second, a number of facts about the situation in commodity markets are inconsistent with the existence of a substantial bubble in commodity prices. Third, available statistical evidence does not indicate that positions for any group in commodity futures markets, including long–only index funds, consistently lead futures price changes. Fourth, there is a historical pattern of attacks upon speculation during periods of extreme market volatility.

description: This paper examines three invited papers focused on commodity prices. Public responses to high nominal commodity prices and perceived increases in price risk have ranged from attempts to assign blame, attempts to change contracting arrangements, and development of public policy that ‘‘protects’’ the market from future occurrences of unacceptable behavior. Interestingly, a result of increased commodity price volatility has suggested that futures markets no longer ‘‘work.’’ This is ironic given that futures markets initially came into existence as tools for managing the negative impacts of commodity price risk. In response to perceptions of market failure some are looking for strategies to regulate the who and how of futures trading.

description: While state government spending on early education has grown in recent years, accessibility of preschool programs for rural children remains a problem. Using census-tract data from a nationally-representative data set on U.S. children, multinomial logit estimation reveals significant differences in early education experiences between rural and nonrural children. Both rural children and children of less-educated mothers are less likely to participate in preschool. This paper concludes by discussing the appropriate role of local, state, or federal governments in funding rural preschool programs. While early educational investments are being touted as effective economic development tools, the nature of the positive externalities associated with preschool makes it unlikely that any single rural community would invest in high-quality programs without state or federal assistance.

description: Community colleges likely draw to college individuals who would otherwise not attend due to their low costs and open admission requirements. This is labeled as the democratization effect. They may also divert individuals away from 4-year to terminal 2-year college degrees (the diversion effect). This study estimates democratization and diversion effects separately for nonmetropolitan and metropolitan youth using nationally representative data and models that account for endogenous institution selection. We find the democratization effect to exceed the diversion effect of community colleges for both metro and nonmetro youth. The democratization-diversion ratio is slightly higher for urban youth.

description: Noncognitive factors such as discipline (and its mirror, punishment in the form of discipline referrals) can affect school and labor market outcomes, human capital development, and thus the economic well–being of communities. It is well–known throughout the United States, but particularly in rural areas of the south that black males drop out of school more frequently than white males, face higher levels of unemployment, and are incarcerated at a disproportionate rate compared with their white cohorts. Also students in low–income homes were three times more likely to drop out than those from average–income homes and nine times more likely than students from high–income homes. This paper tests the hypothesis that the odds of a student being referred for disciplinary action in the middle school setting (8th grade) increases if the student is male, black, in special education classes, or is poor. We conclude that is indeed the case, with the exception of students assigned to special education classes. In particular, we find that low income students are up to eight times more likely to be sent for disciplinary referrals than others. We next tested the hypothesis that the gender and race of the teachers who refer students for disciplinary action have a significant impact on the first hypothesis. Here the evidence that there is a ‘‘color to discipline’’ in this school district is weak.

description: In this paper, we present an (n, n) threshold quantum secret sharing scheme of secure direct communication using Greenberger-Horne-Zeilinger state. The present scheme is efficient in that all the Greenberger-Horne-Zeilinger states used in the quantum secret sharing scheme are used to generate shared secret messages except those chosen for checking eavesdropper. In our scheme, the measuring basis of communication parties is invariable and the classical information used to check eavesdropping needs only the results of measurements of the communication parties. Another nice feature of our scheme is that the sender transmit her secret messages to the receivers directly and the receivers recover the sender's secret by combining their results, different from the QSS scheme whose object is essentially to allow a sender to establish a shared key with the receivers. This feature of our scheme is similar to that of quantum secret direct communication.

description: We present a general symmetry-based framework for obtaining many-body Hamiltonians with scarred eigenstates that do not obey the eigenstate thermalization hypothesis. Our models are derived from parent Hamiltonians with a non-Abelian (or q-deformed) symmetry, whose eigenspectra are organized as degenerate multiplets that transform as irreducible representations of the symmetry (`tunnels'). We show that large classes of perturbations break the symmetry, but in a manner that preserves a particular low-entanglement multiplet of states -- thereby giving generic, thermal spectra with a `shadow' of the broken symmetry in the form of scars. The generators of the Lie algebra furnish operators with `spectrum generating algebras' that can be used to lift the degeneracy of the scar states and promote them to equally spaced `towers'. Our framework applies to several known models with scars, but we also introduce new models with scars that transform as irreducible representations of symmetries such as SU(3) and $q$-deformed SU(2), significantly generalizing the types of systems known to harbor this phenomenon. Additionally, we present new examples of generalized AKLT models with scar states that do not transform in an irreducible representation of the relevant symmetry. These are derived from parent Hamiltonians with enhanced symmetries, and bring AKLT-like models into our framework.

description: From a newly obtained VLT/UVES spectrum we have determined the oxygen abundance of HE 1327-2326, the most iron-poor star known to date. UV-OH lines yield a 1D LTE abundance of [O/Fe]_OH = 3.7 (subgiant case) and [O/Fe]_OH = 3.4 (dwarf case). Using a correction of -1.0 dex to account for 3D effects on OH line formation, the abundances are lowered to [O/Fe] = 2.8 and [O/Fe] = 2.5, respectively, which we adopt. Without 3D corrections, the UV-OH based abundance would be in disagreement with the upper limits derived from the OI triplet lines: [O/Fe]_trip < 2.8 (subgiant) and [O/Fe]_trip < 3.0 (dwarf). We also correct the previously determined carbon and nitrogen abundances for 3D effects. Knowledge of the O abundance of HE 1327-2326 has implications for the interpretation of its abundance pattern. A large O abundance is in accordance with HE 1327-2326 being an early Population II star which formed from material chemically enriched by a first generation supernova. Our derived abundances, however, do not exclude other possibilities such as a Population III scenario.

description: First measurements of charge-independent correlations on angular difference variables $η_1 - η_2$ (pseudorapidity) and $ϕ_1 - ϕ_2$ (azimuth) are presented for primary charged hadrons with transverse momentum $0.15 \leq p_t \leq 2$ GeV/$c$ and $|η| \leq 1.3$ from Au-Au collisions at $\sqrt{s_{NN}} = 130$ GeV. Strong charge-independent angular correlations are observed associated with jet-like structures and elliptic flow. The width of the jet-like peak on $η_1 - η_2$ increases by a factor 2.3 from peripheral to central collisions, suggesting strong coupling of semi-hard scattered partons to a longitudinally-expanding medium. New methods of jet analysis introduced here provide evidence for nonperturbative QCD medium effects in heavy ion collisions.

description: The Renewable Fuel Standard mandates in the Energy Independence and Security Act of 2007 will require 36 billion gallons of ethanol to be produced in 2022. The mandates require that 16 of the 36 billion gallons must be produced from cellulosic feedstocks. The potential land use implications resulting from these mandates were examined using two methods, the POLYSYS model and a general equilibrium model. Results of the POLYSYS analysis indicated that 72.1 million tons of corn stover, 23.5 million tons of wheat straw, and 24.7 million acres would be used to produce 109 million tons of switchgrass in 2025 to meet the mandate. Results of the CGE analysis indicated that 10.9 billion bushels of corn grain, 71 million tons of corn stover, and 56,200 tons of switchgrass is needed to meet the mandate.

description: We analyse the direct detection of neutralino dark matter in the framework of the Next-to-Minimal Supersymmetric Standard Model. After performing a detailed analysis of the parameter space, taking into account all the available constraints from LEPII, we compute the neutralino-nucleon cross section, and compare the results with the sensitivity of detectors. We find that sizable values for the detection cross section, within the reach of dark matter detectors, are attainable in this framework. For example, neutralino-proton cross sections compatible with the sensitivity of present experiments can be obtained due to the exchange of very light Higgses with $m_{h_1^0}\lsim 70$ GeV. Such Higgses have a significant singlet composition, thus escaping detection and being in agreement with accelerator data. The lightest neutralino in these cases exhibits a large singlino-Higgsino composition, and a mass in the range $50\lsim m_{\tildeχ_1^0}\lsim 100$ GeV.

description: Current density distributions in active integrated circuits (ICs) result in patterns of magnetic fields that contain structural and functional information about the IC. Magnetic fields pass through standard materials used by the semiconductor industry and provide a powerful means to fingerprint IC activity for security and failure analysis applications. Here, we demonstrate high spatial resolution, wide field-of-view, vector magnetic field imaging of static (DC) magnetic field emanations from an IC in different active states using a Quantum Diamond Microscope (QDM). The QDM employs a dense layer of fluorescent nitrogen-vacancy (NV) quantum defects near the surface of a transparent diamond substrate placed on the IC to image magnetic fields. We show that QDM imaging achieves simultaneous $\sim10$ $μ$m resolution of all three vector magnetic field components over the 3.7 mm $\times$ 3.7 mm field-of-view of the diamond. We study activity arising from spatially-dependent current flow in both intact and decapsulated field-programmable gate arrays (FPGAs); and find that QDM images can determine pre-programmed IC active states with high fidelity using machine-learning classification methods.

description: While agricultural economics literature has become rife with the economics of ethanol production and cellulosic ethanol feedstock production, little has been written about capital investment necessary for the magnitude of industry development mandated by the Energy Security and Independence Act of 2007. Financing the development of the ethanol industry to meet the 36 billion gallon production capacity set for 2022 (with 16 billion gallons from cellulosic ethanol) will require capital investments exceeding $100 billion for production facilities, plus extensive investment in feedstock establishment and transportation/handling infrastructure. Federal support associated with political mandates does not address all of the financial issues related with the development of the industry in such a relatively short timeframe. This article addresses the challenges associated with and the conditions necessary for achieving the private investment needed to expand the ethanol industry in the United States.
The Thirring-Wess Model Revisited: A Functional Integral Approach

description: We consider the Wess-Zumino-Witten theory to obtain the functional integral bosonization of the Thirring-Wess model with an arbitrary regularization parameter. Proceeding a systematic of decomposing the Bose field algebra into gauge-invariant- and gauge-noninvariant field subalgebras, we obtain the local decoupled quantum action. The generalized operator solutions for the equations of motion are reconstructed from the functional integral formalism. The isomorphism between the QED2 (QCD2) with broken gauge symmetry by a regularization prescription and the Abelian (non-Abelian) Thirring-Wess model with a fixed bare mass for the meson field is established.

description: We investigate the luminosity evolution of the host galaxies of radio-loud AGN through Hubble Space Telescope imaging of 72 BL Lac objects, including new STIS imaging of nine z > 0.6 BL Lacs. With their intrinsically low accretion rates and their strongly beamed jets, BL Lacs provide a unique opportunity to probe host galaxy evolution independent of the biases and ambiguities implicit in quasar studies. We find that the host galaxies of BL Lacs evolve strongly, consistent with passive evolution from a period of active star formation in the range 0.5

description: Ion-irradiated FeCr alloys are useful for understanding and predicting neutron-damage in the structural steels of future nuclear reactors. Previous studies have largely focused on the structure of irradiation-induced defects, probed by transmission electron microscopy (TEM), as well as changes in mechanical properties. Across these studies, a wide range of irradiation conditions has been employed on samples with different processing histories, which complicates the analysis of the relationship between defect structures and material properties. Furthermore, key properties, such as irradiation-induced changes in thermal transport and lattice strain, are little explored. Here we present a systematic study of Fe3Cr, Fe5Cr and Fe10Cr binary alloys implanted with 20 MeV Fe$^{3+}$ ions to nominal doses of 0.01 dpa and 0.1 dpa at room temperature. Nanoindentation, transient grating spectroscopy (TGS) and X-ray micro-beam Laue diffraction were used to study the changes in hardness, thermal diffusivity and strain in the material as a function of damage and Cr content. Our results suggest that Cr leads to an increased retention of irradiation-induced defects, causing substantial changes in hardness and lattice strain. However, thermal diffusivity varies little with increasing damage and instead degrades significantly with increasing Cr content in the material. We find significant lattice strains even in samples exposed to a nominal displacement damage of 0.01 dpa. The defect density predicted from the lattice strain measurements is significantly higher than that observed in previous TEM studies, suggesting that TEM may not fully capture the irradiation-induced defect population.
A Calibration Method for the Generalized Imaging Model with Uncertain Calibration Target Coordinates

description: The developments in optical metrology and computer vision require more and more advanced camera models. Their geometric calibration is of essential importance. Usually, low-dimensional models are used, which however often have insufficient accuracy for the respective applications. A more sophisticated approach uses the generalized camera model. Here, each pixel is described individually by its geometric ray properties. Our efforts in this article strive to improve this model. Hence, we propose a new approach for calibration. Moreover, we show how the immense number of parameters can be efficiently calculated and how the measurement uncertainties of reference features can be effectively utilized. We demonstrate the benefits of our method through an extensive evaluation of different cameras, namely a standard webcam and a microlens-based light field camera.

description: This study presents the design and the kinematic optimization of a novel, underactuated, linkage-based robotic hand exoskeleton to assist users in performing grasping tasks. The device has been designed to apply only normal forces to the finger phalanges during flexion/extension of the fingers, while providing automatic adaptability for different finger sizes. Thus, the easiness of the attachment to the user's fingers and better comfort have been ensured. The analyses of the device kinematic pose, statics, and stability of grasp have been performed. These analyses have been used to optimize the link lengths of the mechanism, ensuring that a reasonable range of motion is satisfied while maximizing the force transmission on the finger joints. Finally, the usability of a prototype with multiple fingers has been tested during grasping tasks with different objects.

description: The paper describes relations between Liouville type theorems for solutions of a periodic elliptic equation (or a system) on an abelian cover of a compact Riemannian manifold and the structure of the dispersion relation for this equation at the edges of the spectrum. Here one says that the Liouville theorem holds if the space of solutions of any given polynomial growth is finite dimensional. The necessary and sufficient condition for a Liouville type theorem to hold is that the real Fermi surface of the elliptic operator consists of finitely many points (modulo the reciprocal lattice). Thus, such a theorem generically is expected to hold at the edges of the spectrum. The precise description of the spaces of polynomially growing solutions depends upon a `homogenized' constant coefficient operator determined by the analytic structure of the dispersion relation. In most cases, simple explicit formulas are found for the dimensions of the spaces of polynomially growing solutions in terms of the dispersion curves. The role of the base of the covering (in particular its dimension) is rather limited, while the deck group is of the most importance. The results are also established for overdetermined elliptic systems, which in particular leads to Liouville theorems for polynomially growing holomorphic functions on abelian coverings of compact analytic manifolds. Analogous theorems hold for abelian coverings of compact combinatorial or quantum graphs.
