description: Two asymptotically valid out-of-sample MSE tests have been developed by Diebold-Mariano (1995) and Stock-Watson (1999). The empirical usefulness of the tests is illustrated through a U.S. wheat model estimated with fixed, recursive and rolling forecasting schemes. Bootstrap methods are adopted to reflect small sample size effect on tests.

description: We present the Y-formalism in the pure spinor quantization of superstring theory in detail. Even if the $ω-λ$ OPE is not completely free owing to the presence of the projector reflecting the pure spinor constraint, it is shown that one can construct at the quantum level a conformal field theory in full agreement with the Berkovits' pure spinor formalism. The OPE's of the two formalisms are the same if we define the relevant operators involving $ω$ in a suitable manner. Moreover the Y-formalism at hand is utilized to find the full expression of the covariant, picture raised $b$ antighost $b_B$, with a reasonable amount of effort.

description: An integrated watershed management framework that combines economic, hydrologic and GIS modeling is developed to study cost effective land retirement in multiple watersheds to achieve off-site sediment reduction goal. This integrated framework examines two alternative standards-a uniform standard under which each watershed is required to achieve the same sediment reduction goal and a non-uniform standard under which marginal cost of sediment abatement is equal across watersheds. Furthermore, for each standard, costs of abatement under two alternative rental instruments based on marginal cost of sediment abatement ($/ton) and uniform payments per acre ($/acre) are examined. Then the cost effectiveness of the four policy options (uniform standard with $/ton and $/acre instrument, non-uniform standard with $/ton and $/acre instrument) is discussed. The integrated framework is applied to 12 agricultural watersheds in Illinois Conservation Reserve Enhancement program (CREP) region. The watersheds varied in size between 29,995 and 70,849 acres. Cropland within 900 feet of streams-129,955 acres (33.4% of all cropland in the 12 watersheds)-is considered eligible for enrollment into the CREP. Consistent with Illinois' program, a sediment reduction goal of 20% is selected for all of the simulations. Policy implications from the empirical results are quite interesting. With either a $/ton or a $/acre instrument, the non-uniform standard, which equalizes marginal cost of abatement across watersheds, outperforms the uniform standard policy. With either a uniform or non-uniform standard, a $/ton instrument outperforms a $/acre instrument. The least preferred policy option, the uniform standard with a $/acre instrument, is 2.5 times as costly as the most preferred policy option, the non-uniform standard with a $/ton instrument. These results suggest that program administrators may want to consider a program that includes a non-uniform standard and a rental payment instrument based on marginal cost of abatement in order to achieve their objectives at least cost.

description: Thermal freeze-out is a prominent example of dark matter (DM) production mechanism in the early Universe that can yield the correct relic density of stable weakly interacting massive particles (WIMPs). At the other end of the mass scale, many popular extensions of the Standard Model predict the existence of ultra-light scalar fields. These can be coupled to matter, preferentially in a universal and shift-symmetry-preserving way. We study the impact of such conformal and disformal couplings on the relic density of WIMPs, without introducing modifications to the thermal history of the Universe. This can either result in an additional thermal contribution to the DM relic density or suppress otherwise too large abundances compared to the observed levels. In this work, we assume that the WIMPs only interact with the standard model via the light scalar portal. We use simple models of fermionic or scalar DM, although a similar discussion holds for more sophisticated scenarios, and predict that their masses should be between $\sim 100~\textrm{GeV}$ and several $\textrm{TeV}$ to comply both with the DM abundance and current bounds on the couplings of the light scalars to matter at the LHC. Future searches will tighten these bounds.

description: Polymer electrolytes are intensely investigated for use as solid electrolytes in next generation lithium-ion and lithium-metal batteries. However, little is known about the structural and dynamical properties of polymer electrolytes close to electrode surfaces. Here, a PEO-LiTFSI polymer electrolyte, confined between two oppositely charged graphite-like electrodes, is studied via molecular dynamics simulations. Three different surface charges of $σ_S = 0$, $\pm 0.5$ and $\pm 1$ $e$/nm$^2$ are considered. Upon charging, a very strong and component-specific layering is observed. Only for the highest surface charge, lithium ions get desolvated and come into direct contact with the negative electrode. The layer structure goes along with the emergence of free energy barriers, which lead to a reduction of the lithium-ion dynamics, as quantified by spatially resolved mean square displacements, corrected for a drift component. Interchain transfers that are known to be very important for long-range lithium-ion transport in polymer electrolytes play no significant role for transitions of lithium ions between different layers.

description: Why are some elections more fraudulent than others? While much work has been devoted to understanding the structural conditions under which election quality can suffer, little is currently understood about election-specific dynamics that shape the conduct of polling day. This study assesses the impact of a more proximate determinant of election day fraud: the anticipated closeness of the race. In doing so, the paper sheds light on a potential paradox of political competition; highly competitive elections are seen as a healthy sign of democratic functioning, yet they may also lead to a reduction in the integrity of the process. Using novel pre-election polling data for 109 presidential elections around the world between 1996 and 2016, results suggest that ex ante closeness incites electoral fraud. In democratic contexts, closer elections – and elections in which the incumbent’s prospects are ambiguous – are associated with greater levels of ballot box manipulation as attempts are made to get over the finish line. This is the case largely irrespective of whether the incumbent is marginally ahead or behind in the race, suggesting that it is the mere uncertainty of the election result that can encourage election day fraud.

description: The model specification problem is perhaps the Achilles heel of applied econometrics. Rather than test down to a single model as is usually done, we estimate 72 different demand systems and use Bayesian averaging procedures over all 72 systems to generate meta estimates of the parameters (e.g., elasticities) of interest.

Population differentiation and conservation of song sparrows (Melospiza melodia) in the San Francisco Bay Area region inferred by morphological and microsattelite loci analysis
Creators: name: Chan, Yvonne Ling-Hsiang
Publisher: name: University of British Columbia
Year: 2009

description: In this study I examined geographic variation in morphology and genetic population structure in five putative subspecies of song sparrows (Melospiza melodia) in the San Francisco Bay region (M. m. samuelis, M. m. maxillaris, M. m. pusillula, M. m. gouldii, and M. m. heermanni). My first goal was to describe genetic population structure at microsatellite loci to assist with conservation and management strategies for song sparrow populations in the San Francisco Bay Area. I sampled nine populations from five putative subspecies and found low estimates of differentiation between populations within subspecies (Fst analog: Φsc = 0.0122, p<0.0001, Rst analog Φsc = 0.00433, p=0.05963) and between subspecies (Fst analog: Φct = 0.0137, p = 0.04985, Rst analog Φct = 0.0174, p=0.09873) at microsatellite loci. Despite low estimates of divergence, genetic structure at the subspecies level was indicated by the larger amount of variance accounted for by subspecies than populations. I propose a Management Unit (MU) consisting of the range of M. m. pusillula be prioritized for conservation efforts based on the larger extent of genetic divergence shown by Cavalli-Sforza and Edward's chord distance and topology of the unweighted pair group cluster analysis which displayed 100% support of bootstrap replicates across loci. Additionally, I propose the ranges of M. m. samuelis and M. m. maxillaris be designated an M U despite low differentiation from M. m. heermanni, because it remains possible that adaptive differences between these types were not identified with neutral loci. The second goal of this study was to compare morphological and genetic estimates of divergence in order to evaluate previous hypotheses proposed for differentiation. Fourteen populations were included in a multivariate analysis of morphological traits and compared with the genetic differentiation derived from microsatellite loci analysis in Chapter 1. In contrast to the low genetic differentiation at microsatellite loci, morphological differentiation was high between song sparrow subspecies. Due to the lack of concordance between estimates of morphological and genetic divergence, selection or phenotypic plasticity in morphology are implicated as causes for morphological differentiation among song sparrow subspecies. It is probable that song sparrow subspecies in the San Francisco Bay region are recently diverged or have high current gene flow and, therefore, that the rate of evolution at morphological traits (assuming a heritable basis for those traits) is faster than at neutral loci.

description: We investigate the effect of radiation reaction on the motion of a wave packet of a charged scalar particle linearly accelerated in quantum electrodynamics. We give the details of the calculations for the case where the particle is accelerated by a static potential that were outlined in Phys.Rev. D 70 (2004) 081701(R) and present similar results in the case of a time-dependent but space-independent potential. In particular, we calculate the expectation value of the position of the charged particle after the acceleration, to first order in the fine structure constant in the $\hbar \to 0$ limit, and find that the change in the expectation value of the position (the position shift) due to radiation reaction agrees exactly with the result obtained using the Lorentz-Dirac force in classical electrodynamics for both potentials. We also point out that the one-loop correction to the potential may contribute to the position change in this limit.

description: Recent observations with the Chandra X-ray telescope continue to detect X-ray emission from the transient GW170817. In a total exposure of 96.6 ks, performed between March 9 and March 16 2020 (935 d to 942 d after the merger), a total of 8 photons are measured at the source position, corresponding to a significance of about 5 sigma. Radio monitoring with the Australian Telescope Compact Array (ATCA) shows instead that the source has faded below our detection threshold (<33 uJy, 3 sigma). By assuming a constant spectral index beta=0.585, we derive an unabsorbed X-ray flux of approximately 1.4E-15 erg/cm^2/s, higher than earlier predictions, yet still consistent with a simple structured jet model. We discuss possible scenarios that could account for prolonged emission in X-rays. The current dataset appears consistent both with energy injection by a long-lived central engine and with the onset of a kilonova afterglow, arising from the interaction of the sub-relativistic merger ejecta with the surrounding medium. Long-term monitoring of this source will be essential to test these different models.

description: We extend the research on contamination effects in mixed-member electoral systems by considering the impact of “dual candidacies” in systems that combine SMD and open-list PR rules. We make three claims. First, we argue that dual-listed candidates have incentives to run campaigns that enable them to maximize their share of personal votes in both tiers. Second, the effect of a dual listing is conditioned by incumbency and party-list position. Finally, we argue that parties themselves benefit from strong dual candidates in the PR list election itself. To test our argument, we analyze the 2016 Lithuanian parliamentary election. Using elite interviews and statistical models of electoral data, our analysis supports our claims. We provide important contribution to contamination literature by demonstrating that parties received a direct, list-tier benefit from nominating SMD candidates, who successfully build personal vote coalitions.

description: SuperKamiokande (SK) doped with gadolinium has the capability to efficiently identify electron-antineutrinos through inverse beta-decay. Given the size of SK and the number of nuclear reactors in its vicinity, we argue that SK can observe the oscillations of reactor antineutrinos driven by the so-called solar mass-squared difference $Δm^2_{21}$. After only one year of data taking, we estimate that SK can measure $Δm^2_{21}$ with enough precision to help inform the current small tension between existing results from KamLAND and solar neutrino experiments.

description: The internet has become a key battleground for political parties and candidates running for office. Using data from three consecutive parliamentary elections in Estonia, spanning across the last decade, we map the extent to which candidates make use of online campaign tools. The availability of candidate survey data over time enables us to evaluate how online campaigning has evolved in a country at the forefront of digitalization. Our findings show that, despite a highly wired context, candidates still do not exploit the internet to its full potential. We observe a significant increment in candidates’ presence on the web, but the effort remains limited in terms of the range of digital campaign tools used. In addition, we find that candidates’ political profile has a limited influence on their digital proclivity, while young age and intensity of their overall campaign effort are stable predictors of it across the decade.

In general all three groups agree on the most important roles and attributes. However, important differences among the groups do exist about the relative importance of certain activities.

description: This study used consumer intercept interviews at farmers markets and organic produce retail stores in northeast Arkansas to determine the variables that influence eco-label usage in organic produce markets. The results indicate that females, those with higher annual incomes, consumers who believe the use of pesticides has negative impact on health and the environment, and those who usually organic purchase organic produce are all more likely to use eco-labels in purchasing organic produce. The findings also suggest that there is a direct relationship between income levels and marginal probability of eco-label usage. The result of this study provides a more current picture of the major determinants that influence eco-label usage among consumers which will be valuable as the USDA proposed organic standards are implemented in the market.

description: Growing deer populations are controlled through changes in hunting regulations including changes in both hunter bag limits and season length. Such action results in direct benefits to hunters and indirect benefits to motorists and the agricultural sector as a lower deer population leads to fewer incidences of human-deer encounters. Traditional recreation demand models are often employed to examine the welfare implications of changes in daily hunting bag limits. Studies measuring the effects of changes in season length, however, are noticeably absent from the literature. This study uses a nested random utility model to examine hunter choice over site and season selection to derive the welfare implications of changes in season length.

description: We discuss the dependence of the phase diagram of a hypothetical isotope of helium with nuclear mass less than 4 atomic mass units. We argue that with decreasing nucleus mass, the temperature of the superfluid phase transition (about 2.2 K in real He-4) increases, while that of the liquid-gas critical point (about 5.2 K in real He-4) decreases. We discuss various scenarios that may occur when the two temperatures approach each other and the order parameters of the superfluid and the liquid-gas phase transitions interact with each other. The simplest scenario, in which both order parameters become critical at particular values of the nuclear mass, temperature, and pressure, can be ruled out through on an analysis of the Landau theory. We argue that in the most likely scenario, as the nuclear mass decreases, first, a tricritical point appears on the line separating the superfluid and the normal fluid phase, then the critical point disappears under the first-order part of superfluid phase transition line, and in the end the tricritical point disappears. The last change in the phase diagram occurs when the two-body scattering length crosses zero, which corresponds to the nuclear mass of about 1.55 u. We develop a quantitative theory that allows one to determine the phase diagram in the vicinity of this point. Finally, we discuss several ways to physically realize such liquids.

description: We present a catalog of the probabilistic redshift estimates and for 1366 individual Long-duration Gamma-Ray Bursts (LGRBs) detected by the Burst And Transient Source Experiment (BATSE). This result is based on a careful selection and modeling of the population distribution of 1366 BATSE LGRBs in the 5-dimensional space of redshift and the four intrinsic prompt gamma-ray emission properties: the isotropic 1024ms peak luminosity, the total isotropic emission, the spectral peak energy, as well as the intrinsic duration, while carefully taking into account the effects of sample incompleteness and the LGRB-detection mechanism of BATSE. Two fundamental plausible assumptions underlie our purely-probabilistic approach: 1. LGRBs trace, either exactly or closely, the Cosmic Star Formation Rate and 2. the joint 4-dimensional distribution of the aforementioned prompt gamma-ray emission properties is well-described by a multivariate log-normal distribution. Our modeling approach enables us to constrain the redshifts of individual BATSE LGRBs to within $0.36$ and $0.96$ average uncertainty ranges at $50\%$ and $90\%$ confidence levels, respectively. Our redshift predictions are completely at odds with the previous redshift estimates of BATSE LGRBs that were computed via the proposed phenomenological high-energy relations, specifically, the apparently-strong correlation of LGRBs' peak luminosity with the spectral peak energy, lightcurve variability, and the spectral lag. The observed discrepancies between our predictions and the previous works can be explained by the strong influence of detector threshold and sample-incompleteness in shaping these phenomenologically-proposed high-energy correlations in the literature.

Characterization of a vanillate non-oxidative decaroxylation gene cluster from streptomyces sp.d7
Creators: name: Chow, Kevin Toshio
Publisher: name: University of British Columbia
Year: 2009

description: The genetics of non-oxidative decarboxylation of aromatic acids to phenolic compounds are poorly understood in both prokaryotes and eukaryotes. Although such reactions have been observed in numerous microorganisms acting on. a variety of substrates, genetic analyses of these processes have not, to my knowledge, been reported in the literature. Previously, I isolated a streptomycete from soil (Streptomyces sp. D7), which efficiently converts 4-hydroxy-3-methoxybenzoic (vanillic) acid to 2-methoxyphenol (guaiacol). Protein two-dimensional gel electrophoresis revealed that several proteins are synthesized in response to vanillic acid, one of which was characterized by partial amino-terminal sequencing, leading to the cloning of a gene cluster from a genomic lambda phage library of Streptomyces sp. D7. This cluster consists of four open reading frames, vdcA (sequencing in progress), vdcB (602 bp), vdcC (1424 bp) and vdcD (239 bp). Protein sequence comparisons suggest that the product of vdcB (201 aa) is similar to phenylacrylate decarboxylase of yeast; the putative products of vdcC (475 aa) and vdcD (80 aa) are similar to hypothetical proteins of unknown function from various microorganisms, and are found in a similar gene cluster in Bacillus subtilis. VdcA is a putative transcriptional regulatory gene. VdcB, vdcC and vdcD homologues are also clustered, along with putative />-cresol methylhydroxylase and vanillin oxidoreductase genes, on the 184 kb catabolic plasmid pNLl of Sphingomonas aromaticivorans F199. Northern blot analysis revealed the synthesis of a 2.5 kb mRNA transcript, which hybridized strongly to a vdcC gene probe, in vanillic acid-induced cells, suggesting that the cluster is under the control of a single inducible promoter. Expression of the entire vdc gene cluster in Streptomyces lividans 1326, as a heterologous host, resulted in that strain acquiring the ability to decarboxylate vanillic acid to guaiacol non-oxidatively. Both Streptomyces strain D7 and recombinant S. lividans 1326 expressing the vdc gene cluster do not, however, decarboxylate structurally similar aromatic acids, suggesting that the system is specific for vanillic acid. By Southern blot hybridization, we detected the presence of the vdc gene cluster in several streptomycetes, including Streptomyces setonii 75Vi2, which has been previously shown to decarboxylate vanillic acid in a nonoxidative reaction. The vanillate decarboxylase catabolic system may be useful as a component for pathway engineering research focused towards the production of valuable chemicals from forestry and agricultural byproducts.

description: We quantify the quantum correlations between two accelerated detectors coupled to a scalar field in a cavity. It has been realized that an accelerated detector will experience a thermal bath, which is termed the Unruh effect. We examine the similarities and differences for quantum correlations regarding either temperature or acceleration. As the accelerations (resp. temperatures) of the detectors increase, the entanglement decreases to zero at some instant but the mutual information (resp. discord) can be amplified. As the accelerations increase but are in opposite directions, the quantum correlations decay. Importantly, we also reveal that larger quantum correlations can appear in certain nonequilibrium scenarios in which either the acceleration difference or the coupling difference becomes significant.

description: We study the coherence of transport of an overdamped Brownian particle in frictional ratchet system in the presence of external Gaussian white noise fluctuations. The analytical expressions for the particle velocity and diffusion coefficient are derived for this system and the reliability or coherence of transport is analysed by means of their ratio in terms of a dimensionless P$\acute{e}$clet number. We show that the coherence in the transport can be enhanced or degraded depending sensitively on the frictional profile with respect to the underlying potential.

description: Radio observations of tidal disruption events (TDEs) probe material ejected by the disruption of stars by supermassive black holes (SMBHs), uniquely tracing the formation and evolution of jets and outflows, revealing details of the disruption hydrodynamics, and illuminating the environments around previously-dormant SMBHs. To date, observations reveal a surprisingly diverse population. A small fraction of TDEs (at most a few percent) have been observed to produce radio-luminous mildly relativistic jets. The remainder of the population are radio quiet, producing less luminous jets, non-relativistic outflows or, possibly, no radio emission at all. Here, we review the radio observations that have been made of TDEs to date and discuss possible explanations for their properties, focusing on detected sources and, in particular, on the two best-studied events: Sw J1644+57 and ASASSN-14li. We also discuss what we have learned about the host galaxies of TDEs from radio observations and review constraints on the rates of bright and faint radio outflows in TDEs. Upcoming X-ray, optical, near-IR, and radio surveys will greatly expand the sample of TDEs, and technological advances open the exciting possibility of discovering a sample of TDEs in the radio band unbiased by host galaxy extinction.

We also report new branching fraction measurements of phi pi^+pi^- and omega p \bar p and upper limits for eta pi^+pi^-, eta K^+K^- and phi p \bar p. Results are compared, where possible, with the corresponding J/psi branching ratios to provide new tests of the 12% rule.

description: Entanglement is a fascinating feature of quantum mechanics and a key ingredient in most quantum information processing tasks. Yet the generation of entanglement is usually hampered by undesired dissipation owing to the inevitable coupling of a system with its environment. Here, we report an experiment on how to entangle two $^{13}$C nuclear spins via engineered dissipation in a nitrogen-vacancy system. We utilize the electron spin as an ancilla, and combine unitary processes together with optical pumping of the ancilla to implement the engineered dissipation and deterministically produce an entangled state of the two nuclear spins, independent of their initial states. Our experiment demonstrates the power of engineered dissipation as a tool for generation of multi-qubit entanglement in solid-state systems.

Path integrals in a multiply-connected configuration space (50 years after)

description: The proposal made 50 years ago by Schulman (1968), Laidlaw & Morette-DeWitt (1971) and Dowker (1972) to decompose the propagator according to the homotopy classes of paths was a major breakthrough: it showed how Feynman functional integrals opened a direct window on quantum properties of topological origin in the configuration space. This paper casts a critical look at the arguments brought by this series of papers and its numerous followers in an attempt to clarify the reason why the emergence of the unitary linear representation of the first homotopy group is not only sufficient but also necessary.

description: Accurate weak lensing mass estimates of clusters are needed in order to calibrate mass proxies for the cosmological exploitation of galaxy cluster surveys. Such measurements require accurate knowledge of the redshift distribution of the weak lensing source galaxies. In this context, we investigate the accuracy of photometric redshifts (photo-$z$s) computed by the 3D-HST team for the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey fields, which provide a relevant photometric reference data set for deep weak lensing studies. Through the comparison to spectroscopic redshifts and photo-$z$s based on very deep data from the Hubble Ultra Deep Field, we identify catastrophic redshift outliers in the 3D-HST/CANDELS catalogue. These would significantly bias weak lensing results if not accounted for. We investigate the cause of these outliers and demonstrate that the interpolation of spectral energy distribution (SED) templates and a well-selected combination of photometric data can reduce the net impact for weak lensing studies.
