description: Pressure-induced superconductivity was studied for a spin-ladder cuprate Sr$_2$Ca$_{12}$Cu$_{24}$O$_{41}$ using nuclear magnetic resonance (NMR) under pressures up to the optimal pressure 3.8 GPa. Pressure application leads to a transitional change from a spin-gapped state to a Fermi-liquid state at temperatures higher than $T_c$. The relaxation rate $1/T_1$ shows activated-type behavior at an onset pressure, whereas Korringa-like behavior becomes predominant at the optimal pressure, suggesting that an increase in the density of states (DOS) at the Fermi energy leads to enhancement of $T_c$. Nuclear quadrupole resonance (NQR) spectra suggest that pressure application causes transfer of holes from the chain to the ladder sites. The transfer of holes increases DOS below the optimal pressure. A dome-shaped $T_c$ versus pressure curve arises from naive balance between the transfer of holes and broadening of the band width.

description: The Bureau of Transportation Statistics (BTS) is one of eleven operating administrations within the U.S. Department of Transportation (DOT). BTS puts together data and information that others need to make decisions concerning transportation. We collect data; compile, analyze and publish statistics; and generally coordinate the statistical programs within DOT. We manage the National Transportation Library, and the Office of Airline Information. We lead the federal effort in developing geo-spatial data for transportation. As one of the federal statistical agencies, BTS maintains a special degree of objectivity and independence. We provide special protections of confidentiality in our data collection, and we provide reports directly to the Secretary and to Congress. We do not advocate policies or programs. Our efforts are focused on getting--and helping to interpret--the data that can be used to better inform decision making, regardless of what the data show.
title: Impact of the Black-Tailed Jackrabbits (Lepus Californicus) on Vegetation in Curlew Valley, Northern Utah
Creators: name: Westoby, Mark
Publisher: name: Utah State University
Year: 1973

description: The interrelations of black- tailed jackrabbits and the desertshrub vegetation on which they were feeding were studied in Curlew Valley, Northern Utah. The vegetation was described as a threecornered continuum, the corners being types dominated respectively by Artemisia tridentata, Atriplex ~ onfertifolia, and Sarcobatus vermiculatus. Jackrabbit diet was studied by microscopic analysis of plant fragments in stomachs from shot animals. The method was inaccurate, apparently because the ratio of identifiable tissues to all ingested tissues was very low, and varied between plant taxa, and seasonally. This problem seems intractable for desert shrub vegetation. The diet was similar to that reported by other workers on this species, with perennial grasses and forbs most important in sprlng and summer, shrubs in autumn and win ter. Features new to this vegetat ion were large percentages of Halogeton glomeratus, particularly in autumn and winter, and intense selection for Kochia americana. Attempts to explain the foods chosen ln terms of t heir nutrient contents were partically successful. Diet selection by large generalist herbivores was conceptualized as optimization of nutrient intake, mediated by long-delay learning, and constrained by food availability only at very low levels of availaoility. Spatial variation in jackrabbit diets confirmed this "cut-offll response to ava i 1 all i 1 i ty . Percentage utilization was estimated indirectly as jackrabbit density, times yearly food consumption per jackrabbit, times yearround percentage of each taxon in the diet, div i ded by available biomass of each taxon. Less abundant plants were more intensely used, which is expected if consumption does not vary continuously with availability. Perennial grasses, Kochia americana and possibly Grayia spinosa seemed to be under damaging pressure at high jackrabbit densities. Kochia had almost disappeared from outside a sheep- and jackrabbitproof exclosure since the 1950 1 s. In other exc1osures, the presence or absence of jackrabbits seemed to make no difference to the rate of vegetation recovery over 5-7 years after exclusion of sheep. Jackrabbit use of a crested wheatgrass seeding was concentrated ln a 300 m band around its edge.
title: Factors Affecting Seeds in a Sagebrush-Steppe Ecosystem and Implications for the Dispersion of an Annual Plant Species, Cheatgrass (Bromus Tectorum L.)
Creators: name: Kelrick, Michael Ira
Publisher: name: Utah State University
Year: 1991

description: I investigated how shrub-induced spatial heterogeneity influenced and was manifested by a representative ground-story plant species at a sagebrush-steppe site in southwestern Wyoming. The dispersion of cheatgrass (Bromus tectorum) reflected differences between undershrub (higher plant densities) and interspace (between shrubs, supporting lower densities) microenvironments, hence the population ecology of this annual species served as a biological probe of shrub-associated patch structure in this community. Since cheatgrass is an annual, factors affecting the seed portion of its life cycle were of special interest. First, attributes of the above- and below-ground seed pool were characterized. The environment-wide seed depositional pattern was assessed using seed traps of several designs, and the legacy of seed incorporation into the soil was examined by separating seeds from soil samples. For both components of the seed pool, annuals' seeds predominated. Seeds at the surface were subject to substantial redistribution, moving readilythrough interspace, and their deposition was related to both the interaction of wind and shrub canopies and the presence of litter. More annuals' seeds were encountered in undershrub than in interspace soils; seeds of cheatgrass were restricted to the soil surface. Second, a manipulative experiment tested effects of granivoryfherbivory and presence/absence of a replicate shrub's canopy upon success of cheatgrass plants arising from known numbers of seeds introduced into undershrub versus interspace microenvironments. While biomass of plants in treatments accessible to herbivores was less than that of protected plants, consumers did not affect plant densities, and herbivore effects were not microenvironment-specific . Shrub canopy removal had no effect on plant success, and, contrary to expectations based on the dispersion of indigenous plants, interspace plants fared better than undershrub counterparts. Finally, demographic fates of individually marked seeds were observed, to disentangle effects of microenvironment from effects of microenvironment-specific surface types on determining safe sites. Littered microsites were strongly associated with undershrub microenvironments, and on these surfaces, cheatgrass seeds were less likely to move and to suffer depredation, and more likely to become favorably positioned for subsequent germination and establishment, than on bare ground surfaces typifying interspace. \

description: We present a photometric study of I-band variability in the young association Cepheus OB3b. The study is sensitive to periodic variability on timescales of less than a day, to more than 20 days. After rejection of contaminating objects using V, I, R and narrowband H-alpha photometry, we find 475 objects with measured rotation periods, which are very likely pre-main-sequence members of the Cep OB3b star forming region. We revise the distance and age to Cep OB3b, putting it on the self-consistent age and distance ladder of Mayne & Naylor (2008). This yields a distance modulus of 8.8 +/- 0.2 mags, corresponding to a distance of 580 +/- 60 pc, and an age of 4-5Myrs. The rotation period distribution confirms the general picture of rotational evolution in young stars, exhibiting both the correlation between accretion (determined in this case through narrowband H-alpha photometry) and rotation expected from disc locking, and the dependence of rotation upon mass that is seen in other star forming regions. However, this mass dependence is much weaker in our data than found in other studies. Comparison to the similarly aged NGC 2362 shows that the low-mass stars in Cep OB3b are rotating much more slowly. This points to a possible link between star forming environment and rotation properties. Such a link would call into question models of stellar angular momentum evolution, which assume that the rotational period distributions of young clusters and associations can be assembled into an evolutionary sequence, thus ignoring environmental effects.

description: This study presents dissolved nitrous oxide (N2O) concentrations in the water column at the Bermuda Atlantic Time-series Study (BATS) station and uses a subset of these measurements to estimate air-to-sea flux for four specific time points between September 2018 and June 2019. N2O concentrations at BATS were in the range of 4.0 nmol L−1–16.9 nmol L−1, with vertical profiles which were the mirror inverse of dissolved oxygen. Regardless of season, N2O concentration maxima were found within the oxygen minimum zone (OMZ). The highest maximum N2O values were observed in November and lowest in October. As the water column at BATS remains consistently at dissolved oxygen concentrations greater than 140 µmol L−1, and therefore aerobic, we assume that the bulk of N2O production occurs through nitrification. A nitrification source is supported by a correlation between excess N2O (ΔN2O) below the mixed layer, apparent oxygen utilization (AOU) and nitrate concentrations. We estimate a pooled average yield of 0.027% to 0.038% N2O from nitrification at BATS. Finally, estimates of air–sea exchange of N2O using regional average monthly wind speeds indicated that this region acts as a weak source or a sink of atmospheric N2O, and varies between months.
Dual parametrization of GPDs versus the double distribution Ansatz

description: We establish a link between the dual parametrization of GPDs and a popular parametrization based on the double distribution Ansatz, which is in prevalent use in phenomenological applications. We compute several first forward-like functions that express the double distribution Ansatz for GPDs in the framework of the dual parametrization and show that these forward-like functions make the dominant contribution into the GPD quintessence function. We also argue that the forward-like functions $Q_{2 ν}(x)$ with $ν\ge 1$ contribute to the leading singular small-$x_{Bj}$ behavior of the imaginary part of DVCS amplitude. This makes the small-$x_{Bj}$ behavior of $\im A^{DVCS}$ independent of the asymptotic behavior of PDFs. Assuming analyticity of Mellin moments of GPDs in the Mellin space we are able to fix the value of the $D$-form factor in terms of the GPD quintessence function $N(x,t)$ and the forward-like function $Q_0(x,t)$.

description: A simple method based on UV/ozone treatment is proposed to control the surface energy of dense grafted silane layers for orientating block copolymer mesophases. Our method allows one to tune the surface energy down to a fraction of a mN/m. We show that related to the surface, perpendicular orientation of a lamellar phase of a PS-PMMA diblock copolymer (neutral surface) is obtained for a critical surface energy of 23.9-25.7 mN/m. Perpendicular cylinders are obtained for 24.6 mN/m and parallel cylinders for 26.8 mN/m.

description: The present study analysed expression of 13 candidate genes in relation to different developmental transitions (vegetative–curding–flowering) in Indian and snowball cauliflwer using quantitative real-time PCR (qRT-PCR). Expression levels of FRUITFULL-c (BoFUL-c), FLOWERING LOCUS T (BoFT), SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1), and LEAFY(BoFLY) increased from seedling to full curd stages in all varieties. VERNALIZATION2 (BoVRN2) and APETALA2 (BoAP2) genes showed a contrasting trend in Pusa Meghna (Indian type) and Pusa Snowball Kt-25 (Snowball type). High expression of BoVRN3, BoVIN2, and BoAP2 in Pusa Snowball Kt-25 fitted well with its vernalisation requirement. The increasing expression of BoFT, SOC1, and BoVIN3 while decreasing trend in BoLFY, REPRODUCTIVE MERISTEM (BoREM1), CAULIFLOWER (BoCAL), and BoFUL-d during seedling–curd initiation–full curd stages in Pusa Shukti (mid-late) matches with Pusa Snowball Kt-25, highlighting their genetic closeness. Hierarchical clustering of these 13 candidate genes grouped all the genes into two major clusters: one had the CAULIFLOWER CURD EXPRESSION 1 (CCE1), BoLFY, BoREM1, BoFUL-c, BoFUL-d, LEAFY Homologous (BoFH), and BoCAL genes while the rest of the genes constituted a second cluster. A significant interaction effect was observed in four candidate varieties and two growing situations (i.e. normal and lower temperature range) for curding-related phenological traits. The information will be helpful in understanding the curding behaviour.

description: We present a study of the classification of z ~1 extremely red objects (EROs), using a combination of HST/ACS, Spitzer/IRAC, and ground-based images of the COSMOS field. Our sample includes about 5300 EROs with i-Ks>2.45 (AB, equivalently I-Ks=4 in Vega) and Ks<=21.1 (AB). For EROs in our sample, we compute, using the ACS F814W images, their concentration, asymmetry, as well as their Gini coefficient and the second moment of the brightest 20% of their light. Using those morphology parameters and the Spitzer/IRAC [3.6]-[8.0] color, the spectral energy distribution (SED) fitting method, we classify EROs into two classes: old galaxies (OGs) and young, dusty starburst galaxies (DGs). We found that the fraction of OGs and DGs in our sample is similar, about 48 percentages of EROs in our sample are OGs, and 52 percentages of them are DGs. To reduce the redundancy of these three different classification methods, we performed a principal component analysis on the measurements of EROs, and find that morphology parameters and SEDs are efficient in segregating OGs and DGs. The [3.6]-[8.0] color, which depends on reddening, redshift, and photometric accuracy, is difficult to separate EROs around the discriminating line between starburst and elliptical. We investigate the dependence of the fraction of EROs on their observational properties, and the results suggest that DGs become increasingly important at fainter magnitudes, redder colors, and higher redshifts.

description: The Gulf of St. Lawrence (GSL) is an Eastern Canada semi-enclosed sea under the influence of the freshwater discharge from the Great Lakes – St. Lawrence River drainage basin. Studying the variability of oceanographic conditions in the GSL under a changing climate is important for ecosystem and fisheries management. To supplement the available in situ sea surface salinity (SSS) measurements with satellite SSS data, this study compares all available years of Soil Moisture Ocean Salinity (SMOS) and Soil Moisture Active and Passive (SMAP) satellite SSS to in situ SSS observations. Despite the relatively cold water and proximity to land and sea ice, the satellite SSS is able to capture the interannual variability and annual cycle of SSS in the GSL, with correlations ranging from 0.80 to 0.85 in the Southern GSL, and 0.22 to 0.77 in the Northern GSL. All satellite SSS data products were able to detect the very low salinity year of 2017 in the Southern GSL.
title: Uniform Temperature Predictions and Temperature Gradient Effects on I-Girder and Box Girder Concrete Bridges
Creators: name: Rojas, Edyson
Publisher: name: Utah State University
Year: 2014

description: In order to more accurately quantify the behavior and degradation of bridges throughout their service life, the Federal Highway Administration lunched the Long-Term Bridge Performance Program. As part of this program an I-girder, integral abutment bridge near Perry, Utah and a two span, box-girder bridge south of Sacramento, California were instrumented with foil strain gauges, velocity transducers, vibrating wire strain gauges, thermocouples, and tiltmeters.
In this research study, data from the thermocouples was used to calculate average bridge temperature and compare it to the recommended design criteria in accordance to the 2010 LRFD Bridge Design Specifications of the American Association of State Highway and Transportation Officials (AASHTO). The design maximum average bridge temperature defined in the 2010 LRFD Bridge Design Specifications was exceeded for both bridges. The accuracy of the 1991 Kuppa Method and the 1976 Black and Emerson Method to estimate the average bridge
temperature based on ambient temperature was studied and a new method that was found to be more accurate was proposed. Long-term predictions of average bridge temperature for both bridges were calculated. Temperature gradients were measured and compared to the 2010 AASHTO LRFD Bridge Design Specifications and the 1978 Priestley Method. Calculated flexural stresses as a function of maximum positive and negative temperature gradients were found to exceed the service limit state established in the 2010 AASHTO LRFD Bridge Design Specifications in the case of the California bridge.
title: Innovative Payloads for Small Unmanned Aerial System-Based Personal Remote Sensing and Applications
Creators: name: Jensen, Austin M.
Publisher: name: Utah State University
Year: 2014

description: Remote sensing enables the acquisition of large amounts of data, over a small period of time, in support of many ecological applications (i.e. precision agriculture, vegetation mapping, etc.) commonly from satellite or manned aircraft platforms. This dissertation focuses on using small unmanned aerial systems (UAS) as a remote sensing platform to collect aerial imagery from commercial-grade cameras and as a radio localization platform to track radio-tagged sh. The small, low-cost nature of small UAS enables remotely sensed data to be captured at a lower cost, higher spatial and temporal resolution, and in a more timely manner than conventional platforms. However, these same attributes limit the types of cameras and sensors that can be used on small UAS and introduce challenges in calibrating the imagery and converting it into actionable information for end users. A major contribution of this dissertation addresses this issue and includes a complete description on how to calibrate imagery from commercial-grade visual, near-infrared, and thermal cameras. This includes the presentation of novel surface temperature sampling methods, which can be used during the ight, to help calibrate thermal imagery. Landsat imagery is used to help evaluate these methods for accuracy; one of the methods performs very well and is logistically feasible for regular use. Another major contribution of this dissertation includes novel, simple methods to estimate the location of radio-tagged fish using multiple unmanned aircraft (UA). A simulation is created to test these methods, and Monte Carlo analysis is used to predict their performance in real-world scenarios. This analysis shows that the methods are able to locate the radio-tagged fish with good accuracy. When multiple UAs are used, the accuracy does not improve; however the fish is located much quicker than when one UA is used.

title: Excimer-Monomer Switching Molecular Beacon: The Study on Synthetic Cryptosporidium DNA Detection, Thermodynamics, and Magnesium Effects
Creators: name: Davis, Michael L.
Publisher: name: Utah State University
Year: 2014

description: Cryptosporidium parvum is a deadly waterborne protozoan parasite that invades the gastrointestinal tract of humans and causes severe to life-threatening gastro enteric disease. Due to the ubiquitous nature of Cryptosporidium parvum in the world’s water, it is necessary to determine the source of an outbreak. Rapid detection and identification of various genotypes of Cryptosporidium are a valuable goal in determining the source of the pathogen in a human epidemic. Exploitation of gene sequences specific to species is a powerful tool detecting pathogens.
Molecular beacons are one of these tools for high selectivity and specificity detection of DNA and RNA. Molecular beacon is a single strand of DNA that forms a stem and loop structure, where the stem holds the DNA together and the loop detects a target sequence. This molecular beacon detection is determined by the changes of fluorescent emissions of fluorescent dye linked to the ends of the stem. In this thesis work, a new and novel molecular beacon was designed to detect the specific sequences from the heat shock protein gene of Cryptosporidium parvum that infects humans. This probe is synthesized by the conjugation of pyrene molecules to both ends of the stem which leads to a unique feature of pyrene excimer-monomer switching molecular beacon upon the hybridization of the loop sequence with the target DNA sequence.
This thesis systematically investigates the physical binding (e.g., quantum yield) and thermodynamic properties, including enthalpy, entropy, and free energy of this excimer-monomer switching molecular beacon in the presences of complimentary, mismatched, and damaged DNA, respectively, in the three phases: phase one is the molecular beacon in the stem and loop structure, phase two is the molecular beacon hybridized to its target DNA, and phase three is the molecular beacon in a random coil. The effect of magnesium concentration on the binding and thermodynamic properties was also investigated. Finally, as a comparison, a conventional fluorescence resonance energy transfer-based molecular beacon with a fluorophore at the 5’ end and quencher at the 3’ end was used to assess selectivity and sensitivity in detection of DNA-DNA hybridization.

description: Various empirical methods that use meteorological data have been developed for estimating evapotranspiration. However, there are currently no online tools available for the estimation of daily evapotranspiration based on user-provided daily data. Here, we introduce ETCalc (https://etcalc.hydrotools.tech), a free, unique online tool that integrates eight methods (i.e. Penman-Monteith, Thornthwaite, Blaney – Criddle, Turc, Priestley – Taylor, Hargreaves, Jensen – Haise and Abtew) for estimation of daily potential evapotranspiration, reference evapotranspiration and, by employing user-defined crop (or cover) coefficients, daily actual evapotranspiration, based on user-provided daily meteorological data. ETCalc has been developed in response to the effort of the Canadian federal government to encourage easier and open access to science and is applicable to any area for which basic meteorological data are available and hence, its suitability is not restricted to particular geographical areas. Through a streamlined interface, ETCalc allows for uploading of user-provided data, tabular and graphical inspection of the input and output data, as well as export of the output data and of the associated metadata. The use of ETCalc is exemplified using 10-year daily meteorological data from Charlottetown, Prince Edward Island, Canada for comparing the output from each of the ETCalc methods and for the calculation of the precipitation deficit.

description: Nitric oxide (NO) plays an important role in plant growth, development, and stress responses. The exogenous NO donor sodium nitroprusside (SNP) increased the plant height, root length, and biomass of tomato seedlings under nitrate stress, especially 100 μM SNP. The reactive oxygen species (ROS) and malondialdehyde (MDA) contents were decreased, while the antioxidant enzyme activities, ascorbate and glutathione contents, and expression of SlTrxh, SlNTRB, SlTpx were increased in tomato after SNP and nitrate stress treatment, compared with nitrate stress. The tomato plants showed shorter root length, more MDA and ROS contents after the NADPH-dependent thioredoxin reductase (NTR) inhibitor Auranofin (ANF) was added, suggesting that ANF inhibited the alleviating effect of NO under nitrate stress. The NO and S-nitrosothiol (SNO) contents and the SlNR transcript levels were decreased and the expression of SlGLB, SlGSNOR was increased after NO and nitrate stress treatment. The S-nitrosylated level in tomato roots was increased after nitrate stress. The SlMDHAR, SlTrxh, and SlNTRB protein were S-nitrosylated after NO and nitrate stress treatment. These results suggested that key enzymes in ascorbate-glutathione cycle and Trx system played an important role in alleviating the effect of NO in tomato seedlings under nitrate stress involving the S-nitrosylation modification.

description: We use the Spitzer IRAC catalogue of the Galactic Center (GC) point sources (Ramirez et al. 2008) and combine it with new isochrones (Marigo et al. 2008) to derive extinctions based on photometry of red giants and asymptotic giant branch (AGB) stars. This new extinction map extends to much higher values of Av than previoulsy available. Our new extinction map of the GC region covers 2.0 x 1.4 degree (280 x 200 pc at a distance of 8 kpc). We apply it to deredden the LPVs found by Glass et al. (2001) near the GC. We make period-magnitude diagrams and compare them to those from other regions of different metallicity. The Glass-LPVs follow well-defined period-luminosity relations (PL) in the IRAC filter bands at 3.6, 4.5, 5.8, and 8.0 micron. The period-luminosity relations are similar to those in the Large Magellanic Cloud, suggesting that the PL relation in the IRAC bands is universal. We use ISOGAL data to derive mass-loss rates and find for the Glass-LPV sample some correlation between mass-loss and pulsation period, as expected theoretically.The GC has an excess of high luminosity and long period LPVs compared to the Bulge, which supports previous suggestions that it contains a younger stellar population.

description: We present a proposal for a combined ICARUS & NOE general purpose detector, to be installed in Hall B of the Gran Sasso Laboratory.The main scientific goal is the one of elucidating in a comprehensive way the pattern of neutrino masses and mixings, following both (1) the S-KAM results and (2) the predictions on atmospheric neutrinos of the large solution of the Solar Neutrinos deficit. To achieve these goals, the experimental method is based upon the complementary and simultaneous detection of CERN beam (CNGS) and cosmic ray (CR) events. This is made possible because of the complete isotropy of the detection technique. For the currently allowed values of the S-KAM results, both CNGS and cosmic ray data will give independent measurements and provide a precise $(sin^{2}2\theta; \Delta m^{2})$ determination rather than a wide band of allowed values. Since we can observe and unambiguously identify $\nu_{e},\nu_{\mu}$ and $\nu_{\tau}$ components, the full (3x3) mixing matrix can be explored, reaching an ultimate sensitivity for CR neutrinos as low as $\Delta m^{2} \approx 10^{-5}eV^{2}$, well above the value observed by the Solar neutrino deficit. All separate processes, electron-CC, muon-CC and NC are equally well observed in all detail with imaging and calorimetric methods, without detector biases and down to kinematical threshold. The detector fruitfully merges the superior imaging quality of the ICARUS with the high resolution full calorimetric containment of NOE, suitably upgraded to provide also magnetic analysis of muons. It has a modular structure of independent supermodules and is expandable by the addition of such supermodules, each consisting of a low density 1.6 kton liquid target and of a high density 0.7 kton active solid target. While the basic concepts of the detector appear well established, this present conceptual design does not represent the final optimization of the complete detector. We plan to continue this process in the following months, in view of the response of scientific committees and of the possible interest of new collaborators.Our present timescale foresees the operation of a first supermodule in 2003 for atmospheric neutrino and nucleon decay physics. Additional modules will be added in the following years and a 4 supermodules 9 Kton configuration will be ready for the start of the CERN-NGS beam in 2005.

description: We discuss the design  of a multi-mirror gas Cerenkov counter to be added to the existing GRAAL apparatus at the European Synchrotron Radiation Facility in Grenoble. The guidelines of the project are reviewed and their impact on the mechanical design is outlined. Several technical procedures adopted to design the bank of mirrors and their support: computer aided engineering (CAE), optical ray-tracing, materials selection, are discussed in detail. Structural analysis has been done to assess reproducibility of optical performances of the detector.

description: L'objet du présent article est d'analyser la relation à court et à long terme entre l'investissement privé et l'investissement public au Maroc sur la période 1980-2020. En utilisant le modèle autorégressif à retards échelonnés (ARDL), les résultats empiriques obtenus indiquent que, à long terme, l'investissement public, le taux d'intérêt et le taux d'inflation ont un effet négatif sur l'investissement privé, tandis que le produit intérieur brut et les crédits accordés au secteur privé favorisent l'attractivité des investissements. En revanche, à court terme, les signes de ces variables s'inversent, à l'exception de l'investissement public, qui reste significativement négatif tant à court terme qu'à long terme.
title: Three Essays on the Economics of Controlling Invasive Species
Creators: name: Liu, Yanxu

description: This dissertation addresses issues pertinent to the control of an invasive species, issues that pertain both to a species’ introduction at a country’s international border and its spread within the country’s border. In the first essay, tariffs and inspections are examined as a joint border control mechanism. In a deterministic setting, where the invasive species level is functionally related to a foreign (i.e., exporting) country’s shipment size, a traditional tariff can be optimal for the home (i.e., importing) country in the short run, but distorts the entry condition for foreign firms and results in a suboptimal industry size in the foreign country in the long run. When the foreign country’s abatement effort determines the invasive species level, an additional home-country tariff on the invasive-species level (which I call an “invasive-species tariff”) is necessary to motivate the foreign firms to abate the invasive species at socially optimal level. In the second essay I consider the case where the invasive species contamination level is jointly determined by the foreign countries’ abating efforts and random environmental factors. The home country may use standard contracts to mitigate imperfect observability caused by the random factors. However, I show that the home country must provide risk-averse foreign countries with higher subsidy rates than the first-best rates with perfect information as compensation for partially bearing the risk. When risk-averse foreign countries face both individualistic and common random environmental factors, a standard tournament scheme is capable of attaining the home country’s first-best invasive-species solution. The third essay addresses the control of an established invasive species outbreak in the home country with multiple spatially-connected individuals. The optimal response to invasion (eradicating, stopping, or ignoring invasion) is determined by the incremental damage of invasion and the marginal control cost. Different spatial scales lead to a divergence between the control incentives of society and individuals, and result in a deficiency of individualistic control, which in turn results in a larger steady-state invasion area. Numerical analysis also demonstrates that the number, size, and spatial configuration of small and large individual land parcels influence the severity of the externality and the insufficiency of privately supplied control. I introduce a dynamic multiple-source-subsidy scheme to internalize the externalities, which prompts individuals to coordinate and follow the social optimal control path without a budget burden on the government.

description: Mirror matter is a stable self-collisional dark matter candidate. If exact mirror parity is a conserved symmetry of nature, there could exist a parallel hidden (mirror) sector of the Universe which has the same kind of particles and the same physical laws of our (visible) sector. The two sectors interact each other predominantly via gravity, therefore mirror matter is naturally "dark". Here I briefly review the cosmological signatures of mirror dark matter, as Big Bang nucleosynthesis, primordial structure formation and evolution, cosmic microwave background and large scale structure power spectra, together with its compatibility with the interpretation of the DAMA annual modulation signal in terms of photon--mirror-photon kinetic mixing. Summarizing the present status of research and comparing theoretical results with observations/experiments, it emerges that mirror matter is not just a viable, but a promising dark matter candidate.

description: In despite of the cyclotron production method and the efficiency of radiochemical processing adopted, the long-lived radioisotopic impurity 202Tl is always present in [201Tl]labelled radiopharmaceuticals (RP) together with other short-living impurities like, 200Tl. A rapid determination of 202Tl impurity, is carried out by HPGe gamma spectrometry of 201Tl  samples, shielded by a 5 mm thick envelope of lead. DT correction errors, random pile-ups, Compton continuum and X-ray fluorescence background, are very efficiently avoided and suppressed. Some experimental results on DT correction performances of a commercial HPGe counting chain are reported. The method described allows determination of 202Tl impurities in 201Tl radiopharmaceuticals with high sensitivity and short counting times. The same method could be applied in Nuclear Medicine routine, to determine 201Tl radioisotopic purity by means of a ionization chamber dose calibrator.
Quantum computation with Turaev-Viro codes

description: The Turaev-Viro invariant for a closed 3-manifold is defined as the contraction of a certain tensor network. The tensors correspond to tetrahedra in a triangulation of the manifold, with values determined by a fixed spherical category. For a manifold with boundary, the tensor network has free indices that can be associated to qudits, and its contraction gives the coefficients of a quantum error-correcting code. The code has local stabilizers determined by Levin and Wen. For example, applied to the genus-one handlebody using the Z_2 category, this construction yields the well-known toric code. For other categories, such as the Fibonacci category, the construction realizes a non-abelian anyon model over a discrete lattice. By studying braid group representations acting on equivalence classes of colored ribbon graphs embedded in a punctured sphere, we identify the anyons, and give a simple recipe for mapping fusion basis states of the doubled category to ribbon graphs. We explain how suitable initial states can be prepared efficiently, how to implement braids, by successively changing the triangulation using a fixed five-qudit local unitary gate, and how to measure the topological charge. Combined with known universality results for anyonic systems, this provides a large family of schemes for quantum computation based on local deformations of stabilizer codes. These schemes may serve as a starting point for developing fault-tolerance schemes using continuous stabilizer measurements and active error-correction.

description: Spiral arm spurs are prominent features that have been observed in extinction and 8$μ$m emission in nearby galaxies. In order to understand their molecular gas properties, we used the Owens Valley Radio Observatory to map the CO(J=1--0) emission in three spurs emanating from the inner northwestern spiral arm of M51. We report CO detections from all three spurs. The molecular gas mass and surface density are M$_{H2} \sim3\times10^6$ M$_{\sun}$ and $Σ_{H2} \sim$50 M$_{\sun}$ pc$^{-2}$. Thus, relative to the spiral arms, the spurs are extremely weak features. However, since the spurs are extended perpendicular to the spiral arms for $\sim$500 pc and contain adequate fuel for star formation, they may be the birthplace for observed inter-arm HII regions. This reduces the requirement for the significant time delay that would be otherwise needed if the inter-arm star formation was initiated in the spiral arms. Larger maps of galaxies at similar depth are required to further understand the formation and evolution of these spurs and their role in star formation - such data should be forthcoming with the new CARMA and future ALMA telescopes and can be compared to several recent numerical simulations that have been examining the evolution of spiral arm spurs.
