description: Vintage-differentiated regulations (VDRs) are standards that are fixed with respect to the date of entry of regulated units, with later vintages facing more stringent standards. VDRs play prominent roles under major Federal, state, and local environmental laws. This paper synthesizes what is known about the effects of environmental VDRs, and develops lessons for public policy and for research. Economic theory suggests that such age-discriminatory regulations retard turnover of the capital stock, drive up the cost of environmental protection, and can increase pollution levels. Empirical studies validate theoretical predictions that VDRs delay replacement of durable goods, and thereby increase aggregate pollution abatement costs. In some cases, empirical studies also validate the perverse consequence that environmental progress is itself retarded.

First, to what extent does induced innovation raise the overall net benefits to society from environmental policies? Second, how does induced innovation affect the appropriate choice among alternative environmental policy instruments? Third, how does it affect the optimal stringency of environmental regulations? Fourth, should environmental policies be supplemented with additional policies to promote innovation, such as research contracts or prizes for new technologies?

description: We characterize control of a qutrit implemented in the lowest three energy levels of a capacitively-shunted flux-biased superconducting circuit. Randomized benchmarking over the qutrit Clifford group yields an average fidelity of 98.89 $\pm$ 0.05%. For a selected subset of the Clifford group, we perform quantum process tomography and observe the behaviour of repeated gate sequences. Each qutrit gate is generated using only two-state rotations via a method applicable to any unitary. We find that errors are due to decoherence primarily and have a significant contribution from level shifts. This work demonstrates high-fidelity qutrit control and outlines avenues for future work on optimal control of superconducting qudits.

Report No. 1 on a Water-Bound, Dense-Graded Aggregate Base
Creators: name: Williams, Ellis G.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1953
Subjects: subject: Transportation Engineering

description: Favorable experience with dense-graded bases containing calcium chloride created interest in similar mixtures containing only water as a bonding agent. As a result of this interest, a project for base and surface construction was set up on the Phil-Pine Grove Road in Casey County to permit study of this method of base construction. The work was carried out during the period of August to October, 1953.  The pavement, which is 11.62 mi. long, was constructed by contract. It had 2 in. of traffic-bound base (creek gravel) and appeared to be in rather uniform condition with few obviously weak areas. Courses constructed in this project were a 3-in. dense-graded base overlain by 1.5 in. of Class C-1 bituminous surface. Aggregate used in both courses consisted entirely of crushed limestone. An RT-2 prime of approximately 0.3 gal. per sq. yd. was applied to the dense- graded base prior to surfacing.  The principle objectives of the project were; to determine the feasibility of using dense graded bases without additives, other than water; and to establish construction methods which avoid raveling or disintergration of the base prior to surfacing.

description: Classical black holes and event horizons are highly non-local objects, defined in relation to the causal past of future null infinity. Alternative, quasilocal characterizations of black holes are often used in mathematical, quantum, and numerical relativity. These include apparent, killing, trapping, isolated, dynamical, and slowly evolving horizons. All of these are closely associated with two-surfaces of zero outward null expansion. This paper reviews the traditional definition of black holes and provides an overview of some of the more recent work on alternative horizons.

description: This paper examines the impact of two popular solid waste programs on the percent recycled of several different materials found in the residential solid waste stream. We examine a unique, national, household-level data set containing information on the percent recycled of five different materials: glass bottles, plastic bottles, aluminum, newspaper, and yard waste. We find that access to curbside recycling has a significant and substantial positive effect on the percentage recycled of all five materials and that the level of this effect varies across different materials. The length of the recycling program's life has a significant and positive effect on two of the five materials and a mandatory recycling requirement does not affect any materials. The level of the unit price has an insignificant effect on all five materials.

Tag-based regulation of modules in genetic programming improves context-dependent problem solving

description: We introduce and experimentally demonstrate the utility of tag-based genetic regulation, a new genetic programming (GP) technique that allows programs to dynamically adjust which code modules to express. Tags are evolvable labels that provide a flexible mechanism for referencing code modules. Tag-based genetic regulation extends existing tag-based naming schemes to allow programs to "promote" and "repress" code modules in order to alter expression patterns. This extension allows evolution to structure a program as a gene regulatory network where modules are regulated based on instruction executions. We demonstrate the functionality of tag-based regulation on a range of program synthesis problems. We find that tag-based regulation improves problem-solving performance on context-dependent problems; that is, problems where programs must adjust how they respond to current inputs based on prior inputs. Indeed, the system could not evolve solutions to some context-dependent problems until regulation was added. Our implementation of tag-based genetic regulation is not universally beneficial, however. We identify scenarios where the correct response to a particular input never changes, rendering tag-based regulation an unneeded functionality that can sometimes impede adaptive evolution. Tag-based genetic regulation broadens our repertoire of techniques for evolving more dynamic genetic programs and can easily be incorporated into existing tag-enabled GP systems.

description: We study DC charge and spin transport through a weakly coupled quantum dot, driven by a non-adiabatic periodic change of system parameters. We generalize the model of Tien and Gordon to simultaneously oscillating voltages and tunnel couplings. When applying our general result to the two-parameter charge pumping in quantum dots, we find interference effects between the oscillations of the voltage and tunnel couplings. Furthermore, we discuss the possibility to electrically pump a spin current in presence of a static magnetic field.

Creators: name: Papovich, Casey

Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: My colleagues and I identified distant red galaxies (DRGs) with J-K>2.3 mag in the GOODS-S field. These galaxies reside at z~1-3.5, (=2.2) and based on their ACS (0.4-1 micron), ISAAC (1-2.2 micron), and IRAC (3-8 micron) photometry, they typically have inferred stellar masses > 10^11 solar masses. Interestingly, more than 50% of these objects have 24 micron flux densities >50 micro-Jy. Attributing the IR emission to star-formation implies SFRs of \~100-1000 solar masses per year. As a result, galaxies with stellar masses >10^11 solar masses have specific SFRs equal to or exceeding the global value at z~1.5-3. In contrast, galaxies with >10^11 solar masses z~0.3-0.75 have specific SFRs less than the global average, and more than an order of magnitude lower than that for massive DRGs at z~1.5-3. Thus, the bulk of star formation in massive galaxies is largely complete by z~1.5. The red colors and large inferred stellar masses in the DRGs suggest that much of the star formation in these galaxies occurred at redshifts z>5-6. Using model star-formation histories that match the DRG colors and stellar masses at z~2-3, and measurements of the UV luminosity density at z>5-6, we consider what constraints exist on the stellar initial mass function in the progenitors of the massive DRGs at z~2-3.

description: Wavelets on the sphere are reintroduced and further developed independently of the original group theoretic formalism, in an equivalent, but more straightforward approach. These developments are motivated by the interest of the scale-space analysis of the cosmic microwave background (CMB) anisotropies on the sky. A new, self-consistent, and practical approach to the wavelet filtering on the sphere is developed. It is also established that the inverse stereographic projection of a wavelet on the plane (i.e. Euclidean wavelet) leads to a wavelet on the sphere (i.e. spherical wavelet). This new correspondence principle simplifies the construction of wavelets on the sphere and allows to transfer onto the sphere properties of wavelets on the plane. In that regard, we define and develop the notions of directionality and steerability of filters on the sphere. In the context of the CMB analysis, these notions are important tools for the identification of local directional features in the wavelet coefficients of the signal, and for their interpretation as possible signatures of non-gaussianity, statistical anisotropy, or foreground emission. But the generic results exposed may find numerous applications beyond cosmology and astrophysics.

description: After much debate and many legislative proposals, the Clean Air Act was amended in 1990 to allow more flexibility in meeting emissions standards for SO2. Specifically, an SO2 emissions allowance trading program was implemented. Firms can meet emission standards by any pollution control method, including buying emission allowances from other firms. Analysts have concluded that, with the changes in the Clean Air Act, SO2 emissions have been reduced by 50 percent and at an estimated $7 billion less than the anticipated cost of the regulatory command-and-control system. Not surprisingly, policy analysts have explored the opportunities for implementing similar market-based systems for water pollution control. Because much of the on-going impairment of surface water has been attributed to nonpoint sources of pollution, trading programs which incorporate both point and nonpoint discharges are of particular interest. However, despite as many as six efforts across the nation to implement point-nonpoint effluent credit trading programs to reduce nutrient discharges to water, there have been few trades to date. This research was undertaken to answer the following question: Do current barriers to effluent credit trading programs arise because of fundamental differences between air and water media or because of differences between institutions affecting air and water use, such as the Clean Air Act and the Clean Water Act? Economic theory offers the situation, structure, conduct, and performance (SSCP) framework, developed by industrial organization economists and extended by institutional and environmental economists, within which to address this research question. In the language of the SSCP framework, the research question can be reframed as: are there fundamental differences in the situation and structure of emission allowance markets and effluent credit markets which result in conduct and performance differences? A comparative analysis of situation and structure suggests that barriers to effective nutrient discharge credit markets are not a result of fundamental differences in the air and water media or the materials being discharged into air and water. Rather, the barriers exist because of structural differences - differences in institutional structure, program design and program implementation. Many of the structural barriers result from the Clean Water Act and its implementation. More flexibility in water pollution prevention would effectively remove many of these barriers.

description: Perturbative Quantum Chromodynamics (pQCD) predicts that the small-$x$ gluons in a hadron wavefunction should form a Color Glass Condensate (CGC), which has universal properties, which are the same for all hadrons or nuclei. Assuming this property, in this paper we cross relate the current CGC descriptions of the $ep$ HERA data and $dAu$ RHIC data. In particular, we use the quark dipole scattering amplitude recently proposed by Kharzeev, Kovchegov and Tuchin (KKT) to explain the high $p_T$ particle suppression observed in $dAu$ collisions at RHIC in our calculations of the proton and longitudinal structure functions. We present a detailed comparison between this parameterization and those proposed to describe the $ep$ HERA data. We find out that, due to its peculiar dependence on the energy and dipole separation, the KKT parameterization is able to describe the experimental $ep$ data only in a limited kinematical range of photon virtualities.

Intertwined Space-Time Symmetry, Orbital Magnetism and Dynamical Berry Curvature in a Circularly Shaken Optical Lattice

description: We study the circular shaking of a two dimensional optical lattice, which is essentially a (2+1) dimensional space-time lattice exhibiting periodicities in both spatial and temporal dimensions. The near-resonant optical shaking considered here dynamically couples the low-lying $s$ band and the first excited $p$ bands by transferring a photon of shaking frequency. The intertwined space-time symmetries are further uncovered to elucidate the degeneracy in the spectrum solved with the generalized Bloch-Floquet theorem. Setting the chirality of circular shaking explicitly breaks time reversal symmetry and lifts the degeneracy of $p_\pm = p_x \pm ip_y$ orbitals, leading to the local circulation of orbital magnetism, i.e the imbalanced occupation in $p_\pm$ orbitals. Moreover, the dynamics of Berry connection is revealed by the time evolution of the Berry curvature and the polarization, which have physical observable effects in experiments. Interestingly, the dynamics is found characterized by a universal phase shift, governed by the time screw rotational symmetry involving a fractional translation of time. These findings suggest that the present lattice-shaking scheme provides a versatile platform for the investigation of the orbital physics and the symmetry-protected dynamics.

description: This paper presents a financial and risk analysis of improved versus traditional maize production technology in Ethiopia, based on yields simulated with the CERES-Maize crop growth model (Schulthess and Ward, 2000). The purpose is to analyze the potential performance of the SG2000/Ministry of Agriculture program technology under less favorable meteorological conditions (rainfall level and distribution), and in areas with lower agroecological potential than those covered by the SG2000/MOA program through 1998. At the time of this study, expansion of the MOA program into lower potential zones seemed likely. Results show that use of fertilizer and improved seed is highly profitable under a variety of assumptions about crop growth conditions, maize prices, and fertilizer costs. Risk is examined using simple sensitivity and breakeven analysis, and stochastic dominance analysis.
Economics of multiple-use forest management : spatial considerations
Creators: name: Bogdanski, Bryan E.C.
Publisher: name: University of British Columbia
Year: 2009

description: Historically, Canada's productive forests have been assumed to be reserved for timber use while nonproductive lands have been reserved for other uses. However, demands on Canada's forestlands are becoming increasingly more diverse and traditional timber harvesting practices are now being scrutinized with regard to their consistency with these new demands. The response by provincial and federal policy makers has been a movement towards the concept of multiple-use forest management. However, due to the numerous meanings of the concept, policy makers and practitioners are finding it difficult to implement this new direction. Many of the issues surrounding forest management for multiple use are spatial in nature. Problems include where (location) to manage for single or multiple goods and services, and what scale (size) to choose for management units. The spatial issue, the issue of where, is of great importance in multiple-use forest management, because location is central to the long standing debate in forestry as to whether certain forest areas should be allocated to specialized or general multiple-use management. This dissertation focuses on the problem of modeling the issue of space in an economic model of multiple-use forestry. The study first involves modeling the problem of managing a two-stand forest over a two-period time horizon with and without intensive timber management and then solving a three-stand forest for several case studies by numerical simulation. The analytical and simulation results suggest that relative prices, the discount rate, forest productivity, nontimber productivity, and interdependencies between forest stands are all important determinants of the optimal harvesting and inventory solutions. Within a multiple-stand forest, areas are managed similarly if complementarity exists between stands and differently if substitutability exists between the stands in producing nontimber values, ceteris paribus. The results support both zoning for intensive timber management and integrated resource management everywhere. Thus, there is no a priori optimal management paradigm in forestry. However, intensive timber zones are supported under particular circumstances. Furthermore, the result suggest that forest policy tools, such as forest practices laws and forest land-use zoning, need to be flexible over time and space to promote and achieve efficient resource allocation.

description: We report on the pressure dependence of the Hall coefficient $R_H$ in quasi-2D heavy fermion CeCoIn$_5$. At ambient pressure, below a temperature associated with the emergence of non-Fermi liquid properties, $R_H$ is anomalously enhanced. We found that the restoration of the Fermi liquid state with applied pressure leads to a gradual suppression of this dramatic enhancement. Moreover, the enhancement in $R_H$ was found to be confined to an intermediate temperature window, where inelastic electron-electron scattering is dominant. Our results strongly support the presence of cold and hot spots on the Fermi surface probably due to anisotropic scattering by antiferromagnetic fluctuations, which may also prove relevant for the debate on the anomalous normal-state properties of high-$T_c$ cuprates.

description: An automatic target monitoring method based on photographs taken by a CMOS photo-camera has been developed for the MEG II detector. The technique could be adapted for other fixed-target experiments requiring good knowledge of their target position to avoid biases and systematic errors in measuring the trajectories of the outcoming particles. A CMOS-based, high resolution, high radiation tolerant and high magnetic field resistant photo-camera was mounted inside the MEG II detector at the Paul Scherrer Institute (Switzerland). MEG II is used to search for lepton flavour violation in muon decays. The photogrammetric method's challenges, affecting measurements of low momentum particles' tracks, are high magnetic field of the spectrometer, high radiation levels, tight space constraints, and the need to limit the material budget in the tracking volume. The camera is focused on dot pattern drawn on the thin MEG II target, about 1 m away from the detector endcaps where the photo-camera is placed. Target movements and deformations are monitored by comparing images of the dots taken at various times during the measurement. The images are acquired with a Raspberry board and analyzed using a custom software. Global alignment to the spectrometer is guaranteed by corner cubes placed on the target support. As a result, the target monitoring fulfils the needs of the experiment.

Starting from the observations that (1) SNIa occur predominantly in spiral galaxies, (2) star-formation ejects ISM out of the plane of spirals, (3) star-formation alters the extinction properties of the dust in the ISM, and (4) there is substantially more star-formation at higher redshift, I propose that spiral galaxies have a dustier halo in the past than they do now. The ejected material's lower value of $R_V$ will lead to a lower average value ($\bar{R}_V$) for SNIa observed at higher redshift. Two relations in SNIa observations indicate evolution of the average $R_V$: the relation of observed $R_V$ with inclination of the host galaxy at low redshift and the matching of the distribution of extinction values ($A_V$) for SNIa in different redshift intervals. The inclination effect does point to a halo with lower $R_V$ values. In contrast, the distributions of $A_V$ values match best for a $\bar{R}_V(z)$ evolution that mimics the relation of SNIa dimming with redshift attributed to the cosmological constant. However, even in the worse case scenario, the evolution $\bar{R}_V$ can not fully explain the dimming of SNIa: host galaxy extinction law evolution is not a viable alternative to account for the dimming of SNIa. Future observations of SNIa --multi-color lightcurves and spectra-- will solve separately for values of $A_V$ and $R_V$ for each SNIa . Solving for evolution of $\bar{R}_V$ (and $A_V$) with redshift will be important for the coming generation of cosmological SNIa measurements and has the bonus science of insight into the distribution of dust-rich ISM in the host galaxies in the distant past.

description: We discuss the systematics of ground-state quadrupole correlations of binding energies and mean-square charge radii for all even-even nuclei, from O16 up to the superheavies, for which data are available. To that aim we calculate their correlated J=0 ground state by means of the angular-momentum and particle-number projected generator coordinate method, using the axial mass quadrupole moment as the generator coordinate and self-consistent mean-field states only restricted by axial, parity, and time-reversal symmetries. The calculation is performed within the framework of a non-relativistic self-consistent mean-field model using the same non-relativistic Skyrme interaction SLy4 and a density-dependent pairing force to generate the mean-field configurations and mix them. (See the paper for the rest of the abstract).

description: This paper aims at investigating the existence of localized stationary waves in the shallow subsurface whose constitutive behaviour is governed by the hyperbolic model, implying non-polynomial nonlinearity and strain-dependent shear modulus. To this end, we derive a novel equation of motion for a nonlinear gradient elasticity model, where the higher-order gradient terms capture the effect of small-scale soil heterogeneity/micro-structure. We also present a novel finite-difference scheme to solve the nonlinear equation of motion in space and time. Simulations of the propagation of arbitrary initial pulses clearly reveal the influence of the nonlinearity: strain-dependent speed in general and, as a result, sharpening of the pulses. Stationary solutions of the equation of motion are obtained by introducing the moving reference frame together with the stationarity assumption. Periodic (with and without a descending trend), as well as localized stationary waves, are found by analyzing the obtained ordinary differential equation in the phase portrait, and integrating it along the different trajectories. The localized stationary wave is in fact a kink wave and is obtained by integration along a homoclinic orbit. In general, the closer the trajectory lies to a homoclinic orbit, the sharper the edges of the corresponding periodic stationary wave and the larger its period. Finally, we find that the kink wave is in fact not a true soliton as the original shapes of two colliding kink waves are not recovered after interaction. However, it may have high amplitude and reach the surface depending on the damping mechanisms (which have not been considered). Therefore, seismic site response analyses should not a priori exclude the presence of such localized stationary waves.

description: We study the phenomenon of wave packet revivals of Bloch electrons and explore how to control them by a magnetic field for quantum information transfer. It is showed that the single electron system can be modulated into a linear dispersion regime by the "quantized" flux and then an electronic wave packet with the components localized in this regime can be transferred without spreading. This feature can be utilized to perform the high-fidelity transfer of quantum information encoded in the polarization of the spin. Beyond the linear approximation, the re-localization and self-interference occur as the novel phenomena of quantum coherence.

A predictive model for archaeological potential for a locality in the Interior Plateau of British Columbia
Creators: name: Oriente, Damon
Publisher: name: University of British Columbia
Year: 2009

description: Consideration of heritage resources in forestry in British Columbia was mandated by the Forest Practices Code in 1993. Heritage resource planning and management in forestry, however, is often not as easily accomplished as traditional conventional scientific concerns. This is in part due to the nature of the resource. It is considered that less than half of the extant archaeological sites in the Province are known, and the physical presence of many sites are not readily apparent or are difficult to determine without physical examination. This study utilizes normally available biophysical data in digital form to develop a predictive model for heritage potential for a locality in the British Columbia interior. A specific set of environmental criteria are selected, the study site is analyzed for areas satisfying the model criteria, and the appropriate areas are overlaid graphically to produce a predictive map. Finally, the predictive map is coregistered with data of known archaeological sites to evaluate the model. Results from the testing overlay indicate that the area described as having high archaeological potential contains 73% of the currently known sites. These results suggest a positive relationship between the combination of the selected environmental criteria and the location of known sites for the study area. The paper includes research into other predictive models and related archaeological literature, an overview of interior British Columbia pre-history, and reports on consultation with Native Indian persons who live in the area.

description: Based upon spin-lattice interaction, we propose a theoretical model for the phonon Hall effect in paramagnetic dielectrics. The thermal Hall conductivity is calculated by using the Kubo formula. Our theory reproduces the essential experimental features of the phonon Hall effect discovered recently in ionic dielectric Tb$_3$Ga$_5$O$_{12}$, including the sign, magnitude and linear magnetic field dependence of the thermal Hall conductivity.
