description: The author has proved that a crepant resolution Y of a Ricci-flat Kähler cone X admits a complete Ricci-flat Kähler metric asymptotic to the cone metric in every Kähler class in H^2_c(Y,\R). These manifolds are generalizations of the Ricci-flat ALE Kähler spaces known by the work of P. Kronheimer, D. Joyce and others. This article considers further the problem of constructing examples. We show that every 3-dimensional Gorenstein toric Kähler cone admits a crepant resolution for which the above theorem applies. This gives infinitely many examples of asymptotically conical Ricci-flat manifolds. Then other examples are given of which are crepant resolutions hypersurface singularities which are known to admit Ricci-flat Kähler cone metrics by the work of C. Boyer, K. Galicki, J. Kollár, and others. Two families of hypersurface examples are given which are distinguished by the condition b_3(Y)=0 or b_3(Y)>0.

title: Movement of Air Through Submerged Air Vents
Creators: name: Woods, Clay W.
Publisher: name: Utah State University
Year: 2011

description: A series of physical models consisting of three different diameter pipes at the same 4% slope were studied at the Utah Water Research Laboratory (UWRL). Various combinations of air flow and head on the pipe were used to determine the effect of pipe diameter, head, and air flow on the behavior of air bubbles introduced into the pipes and to determine the venting capacity of the pipes. It was determined that neither bubble velocity nor bubble length changes with pipe diameter or head changes within the range tested. It was also determined that bubble velocity and length will increase with increased air flow. Bubble velocity also increased with increasing bubble length consistent with prior research. Overall the venting capacity of a pipe is dependent upon having a large enough pipe to prevent slug flow. A procedure was developed to aid in the sizing of submerged vent piping during the design of pipelines based on the data collected during this study and utilizing prior research.

title: Characterizing Water and Nitrogen Dynamics in Urban/Suburban Landscapes
Creators: name: Sun, Hongyan
Publisher: name: Utah State University
Year: 2011

description: This research investigated the water use of different plant types in urban landscapes, nitrogen (N) and water transport in turf, and potential N leaching from urban landscapes to ground water. In the first study, three landscape treatments integrating different types of plants—woody, herbaceous perennial, turf—and putative water use classifications—Mesic, Mixed, Xeric—were grown in large drainage lysimeters. Each landscape plot was divided into woody, turf, and herbaceous perennial plant hydrozones and irrigated for optimum water status over two years, with water use measured using a water balance approach. For woody plants and herbaceous perennials, canopy cover, rather than plant type or water use classification, was the key determinant of water use relative to reference evapotranspiration (ETo) under well-watered conditions. For turf, monthly evapotranspiration (ETa) followed a trend linearly related to ETo. In the second study, water transport parameters were calibrated using an inverse simulation with Kentucky bluegrass (KBG). Subsequently, those parameters were applied to simulate water use by tall fescue (TF) and buffalograss (BG) turfgrasses using numerical modeling (Hydrus-1D). By using the calibrated soil hydraulic parameters obtained from the water transport simulation, N transport and transformation was modeled with Hydrus- 1D under different irrigation rates and different fertilization rates. Different soil texture scenarios were also simulated to demonstrate the influence of soil texture on N leaching. In the third study, the simulated N-leaching from different soil textures was integrated into a Geographic Information System (GIS) approach to estimate NO3-N leaching mass from urban turf areas. Nitrate-N leaching risks to ground water under overirrigation and overfertilization scenarios and efficient irrigation and fertilization scenarios were estimated. The results showed improvement of turf irrigation and fertilization management may decrease N-leaching significantly and greatly decrease the risk of ground water being contaminated by NO3-N leaching in the Salt Lake Valley.
A Measurement of the t-tbar Cross Section in p-pbar Collisions at sqrt(s) = 1.96 TeV using Dilepton Events with a Lepton plus Track Selection

description: This paper reports a measurement of the cross section for the pair production of top quarks in ppbar collisions at sqrt(s) = 1.96 TeV at the Fermilab Tevatron. The data was collected from the CDF II detector in a set of runs with a total integrated luminosity of 1.1 fb^{-1}. The cross section is measured in the dilepton channel, the subset of ttbar events in which both top quarks decay through t -> Wb -> l nu b where l = e, mu, or tau. The lepton pair is reconstructed as one identified electron or muon and one isolated track. The use of an isolated track to identify the second lepton increases the ttbar acceptance, particularly for the case in which one W decays as W -> tau nu. The purity of the sample may be further improved at the cost of a reduction in the number of signal events, by requiring an identified b-jet. We present the results of measurements performed with and without the request of an identified b-jet. The former is the first published CDF result for which a b-jet requirement is added to the dilepton selection. In the CDF data there are 129 pretag lepton + track candidate events, of which 69 are tagged. With the tagging information, the sample is divided into tagged and untagged sub-samples, and a combined cross section is calculated by maximizing a likelihood. The result is sigma_{ttbar} = 9.6 +/- 1.2 (stat.) -0.5 +0.6 (sys.) +/- 0.6 (lum.) pb, assuming a branching ratio of BR(W -> ell nu) = 10.8% and a top mass of m_t = 175 GeV/c^2.

title: Optimization of Dissolved Air Flotation for Algal Harvesting at the Logan, Utah Wastewater Treatment Plant
Creators: name: Elder, Andrew R.
Publisher: name: Utah State University
Year: 2011

description: This research evaluated dissolved air flotation (DAF) as a separation method for algae and phosphorus from municipal wastewater at the City of Logan, Utah Wastewater Reclamation Facility. DAF uses the supersaturation of air to raise suspended algae and other particles to the surface, where they can be easily removed. DAF, in conjunction with chemical coagulants and flocculants, can approach 95% algae and phosphorus removal. The algae removed using the DAF process will be used in the production of biofuels and bioplastics.
A pilot DAF unit was used to determine the optimum alum dose for total phosphorus (TP) and algae removal. In addition, a bench-scale jar test unit was used to study the effects of various alum and polymer doses on removal efficiencies at different times of the day. An optimal alum dose was found to be 30 mg/L based on results from both the pilot and bench-scale units. No advantage to adding polymer was found.
Algae removal efficiencies on the pilot DAF ranged from 68-70%, and the effluent algae concentration was reduced to 10 mg/L. Approximately 65% of the total phosphorus was removed, from 1.1 to 0.4 mg/L, which is low enough to meet regulations anticipated to be promulgated by the state of Utah. Using the assumption that the molar weight of algae is 3,550 g/mole, the molar ratio of Al/TSS was found to be 30.1 and the molar ratio of Al/TP was found to be 7.5.
Extracellular polymeric substances (EPS) excreted by algal cells act as a natural flocculant and may allow for chemical usage to be minimized. Autoflocculation and bioflocculation, natural processes caused by EPS production and an increased pH level, were not observed to be a significant factor.
The chemical dosing rates provide the City of Logan with basic operational parameters for a full-scale (15 million gallons per day) DAF plant, providing an effluent phosphorus level below 0.5 mg/L. The alum will cost $1,118 per day, with a daily electrical cost of approximately $149. This full-scale DAF plant would harvest 1,563 kg of algal biomass per day, with a cost per kilogram of algae at $0.81.
title: Class-wide Respect and Social Support Skill Training to Increase Peer Interactions of Students with Autism Spectrum Disorders
Creators: name: Orton, Melanie
Publisher: name: Utah State University
Year: 2011

description: The demand for effective social skills interventions for children with autism spectrum disorders is a pertinent issue for school-based professionals. One approach to increase appropriate social skills is to involve peer support by training a few socially competent children to positively interact with a student with an ASD. Potentially, training larger groups of children could result in increasing the number of different peers who would actively support positive interactions with their classmates with ASD. Thus, the present study investigated the effect of a class-wide peer-training strategy on the percentage of positive social interaction and number of peer contacts for three elementary students with autism spectrum disorders. All peers in the three different classrooms received a brief lesson on respecting differences in others and how to support all classmates during classroom and recess activities. Next, each class was taught how to support other students in the class by modeling, role playing, and didactic instruction. This training specifically targeted preferred recess activities and social skills goals of the student with an ASD. After training, peers received a verbal prompt to use skills before a recess period, implemented the procedures in the absence of direct supervision during recess, and participated for a chance to earn points towards a class-wide reward for participating in positive interactions with the student with an ASD. A multiple baseline across the three classrooms showed replicated positive effects of the intervention relative to a prior baseline condition. Results showed that the class-wide respect and social support skills training paired with a contingent reward contingency increased the level of positive social interactions as well as the number of peer contacts for all three students with autism spectrum disorders.

description: The objects of this research were twofold: 1. To develop apparatus and experimental techniques to shorten the exposure times in the study of the vibrational Raman effect of liquids and liquids in the solid state. 2. To use the above in the investigation of the vibrational Raman spectra of the liquid and solid states of Carbon Disulfide. Concurrently, other workers were investigating the infrared absorption spectrum of CS2. The two projects, when integrated, should give a reasonably complete basis for the description of the CS2 molecule.

Collective modes as a probe of imbalanced Fermi gases

description: We theoretically investigate the collective modes of imbalanced two component one-dimensional Fermi gases with attractive interactions. This is done for trapped and untrapped systems both at zero and non-zero temperature, using self-consistent mean-field theory and the random phase approximation. We discuss how the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state can be detected and the periodicity of the associated density modulations determined from its collective mode spectrum. We also investigate the accuracy of the single mode approximation for low-lying collective excitations in a trap by comparing frequencies obtained via sum rules with frequencies obtained from direct collective mode calculations. It is found that, for collective excitations where the atomic clouds of the two spin species oscillate largely in phase, the single mode approximation holds well for a large parameter regime. Finally we investigate the collective mode spectrum obtained by parametric modulation of the coupling constant.

title: Under What Conditions Do Community Demographics Influence Aggregate Recycling?
Creators: name: Kotter, Edward
Publisher: name: Utah State University
Year: 2011

description: Diversion rates of solid waste due to recycling and other efforts vary across communities for multiple reasons. Past research has provided demographic and attitudinal profiles of recyclers and non-recyclers at mainly the individual and household levels with some at the community level. Researchers have found both commonalities and variations in these profiles. Studies have also looked at how the structure of a recycling program influences recycling behavior. The question asked here is how community-level demographic and attitudinal characteristics interact with the structure of public recycling programs to influence aggregate rates of recycling participation and diversion in 40 cities in the western United States.
The results of this study provide modest support for my hypotheses that when recycling programs are less convenient, demographics and attitudinal characteristics will explain more variation in diversion of waste at the community scale. Similarly, as recycling programs become more convenient, the roles of demographic and attitudinal factors (recycling friendliness) are expected to decrease. This study found increased recycling program convenience and less visible fee assessment structures were associated with higher rates of recycling among cities regardless of their degree of recycling friendliness. When recycling outcomes were cross tabulated with indicators convenience and fee assessment, low rates were generally found among cities with low program convenience and high rates were generally found among cities with high program convenience. Cities with less convenient programs were more likely to see higher rates of recycling when their underlying demographic and attitudinal attributes reflected characteristics that have been associated with increased recycling activity. However, when program convenience was high (and fee structures less visible) high rates of recycling were found across cities with both favorable and unfavorable demographic characteristics. I use case-specific detailed narratives to explore the factors that influence outcomes among selected cities that did or did not meet my expectations.

description: The stability of isotropic cosmological solutions in the Bianchi I model is considered. We prove that the stability of isotropic solutions in the Bianchi I metric for a positive Hubble parameter follows from their stability in the Friedmann-Robertson-Walker metric. This result is applied to models inspired by string field theory, which violate the null energy condition. Examples of stable isotropic solutions are presented. We also consider the k-essence model and analyse the stability of solutions of the form $Φ(t)=t$.

title: Evaluation of an Incompressible Energy-Vorticity Turbulence Model for Fully Rough Pipe Flow
Creators: name: Hunsaker, Doug F.
Publisher: name: Utah State University
Year: 2011

description: Traditional methods of closing the Boussinesq-based Reynolds-averaged Navier-Stokes equations are considered, and suggestions for improving two-equation turbulence models are made. The traditional smooth-wall boundary conditions are shown to be incorrect, and the correct boundary conditions are provided along with sample solutions to traditional models. The correct boundary condition at a smooth wall for dissipation-based turbulence models is that which forces both the turbulent kinetic energy and its first derivative to zero. Foundations for an energy-vorticity model suggested by Phillips are presented along with the near-smooth-wall behavior of the model. These results show that at a perfectly smooth wall, the turbulent kinetic energy may approach the wall at a higher order than is generally accepted. The foundations of this model are used in the development of a k-λ model for fully rough pipe flow. Closure coefficients for the model are developed through gradient-based optimization techniques. Results of the model are compared to results from the Wilcox 1998 and 2006 k-ω models as well as four eddy-viscosity models. The results show that the Phillips k-λ model is much more accurate than other models for predicting the relationship between Reynolds number and friction factor for fully rough pipe flow. However, the velocity profiles resulting from the model deviate noticeably from the law of the wall.

description: We investigate a non-equilibrium ionization state and an electron-ion two-temperature structure of the intracluster medium (ICM) in merging galaxy clusters using a series of N-body and hydrodynamic simulations. Mergers with various sets of mass ratios and impact parameters are systematically investigated, and it is found that, in most cases, ICM significantly departs from the ionization equilibrium state at the shock layers with a Mach number of ~1.5-2.0 in the outskirts of the clusters, and the shock layers with a Mach number of ~2-4 in front of the ICM cores. Accordingly, the intensity ratio between Fe xxv and Fe xxvi K alpha line emissions is significantly altered from that in the ionization equilibrium state. If the effect of the two-temperature structure of ICM is incorporated, the electron temperature is ~10-20 % and ~30-50 % lower than the mean temperature of ICM at the shock layers in the outskirts and in front of the ICM cores, respectively, and the deviation from the ionization equilibrium state becomes larger. We also address the dependence of the intensity ratio on the viewing angle with respect to the merging plane.

Phonon lineshapes in atom-surface scattering

description: Phonon lineshapes in atom-surface scattering are obtained from a simple stochastic model based on the so-called Caldeira-Leggett Hamiltonian. In this single-bath model, the excited phonon resulting from a creation or annihilation event is coupled to a thermal bath consisting of an infinite number of harmonic oscillators, namely the bath phonons. The diagonalization of the corresponding Hamiltonian leads to a renormalization of the phonon frequencies in terms of the phonon friction or damping coefficient. Moreover, when there are adsorbates on the surface, this single-bath model can be extended to a two-bath model accounting for the effect induced by the adsorbates on the phonon lineshapes as well as their corresponding lineshapes.

description: Dans ce travail nous avons voulu évaluer l’impact de la pédagogie coopérative (PC) sur le développement des capacités transversales décrites dans le PER. Nous nous sommes basés sur l’approche nord-américaine du « coopérative learning » et avons placé notre perspective de recherche sur la PC. Cette dernière, au contraire de l’apprentissage coopératif dérivé lui aussi du « coopérative learning », considère le milieu de la classe comme faisant partie des variables à considérer lors de la préparation des leçons. En effet, pour que cette pédagogie développe tous ses bienfaits, il faut d’abord préparer la classe à la coopération afin de créer un climat propice aux apprentissages. La mise en avant de valeurs correspondant à la PC a été utilisée pour cette étape. Puis, il faut ensuite préparer les élèves à la coopération, selon la maxime : « Apprendre à coopérer afin de coopérer pour apprendre ». Lorsque que ces deux étapes ont été franchies, la PC permet de favoriser les apprentissages. Notre recherche s’est déroulée dans deux classes différentes (11 VG niveau 2, 9 VP) en Suisse romande pendant les périodes d’enseignement des mathématiques. Nous avons effectué des activités coopératives sur une période de huit semaines. Chaque séance de PC a été associée à une présentation des valeurs et des habilités sociales et cognitives en jeu dans l’activité. Nous avons utilisé la recherche-action comme méthode de recherche. Pour la collecte des données, nous avons mis en place un questionnaire nous permettant de mesurer la progression des capacités transversales. Ce questionnaire a été donné aux élèves au début et à la fin des activités de PC. Il a été complété par un entretien effectué avec deux élèves de chaque classe pour approfondir certains aspects de la recherche. Les résultats ont montré une progression dans la capacité transversale de « Démarche réflexive/Remise en question et décentration de soi ». Cette recherche a montré l’impact de l’âge sur la qualité de la collaboration, ainsi que les difficultés à mettre en place la PC dans le cursus scolaire.

description: Human experience fluctuates throughout time. The relationship of these subjective experiences to changing brain states has yet to be fully understood. We used an existing MRI dataset in which participants watched movies in the scanner. In an online study, we had participants continuously rate their subjective experiences while watching the same movie clips. We expand on prior research identifying four common latent neural states by looking at the relationship between occurrence of these states and subjective experience. Participant responses of either engagement, arousal, valence, social interaction, focus, curiosity, relatability, importance, surprise, comprehension, or boredom were then compared to the latent state occurrences of either the default mode network (DMN), dorsal attention network (DAN), somatosensory motor (SM), or base states. When the DMN state occurred, participants indicated higher levels of engagement, arousal, external focus, positivity, and sociality. When the DAN state occurred, participants indicated higher levels of surprise, and lower levels of boredom and social interaction. When the SM state occurred, participants indicated low levels of engagement, arousal, curiosity, importance and surprise, as well as negativity, internal focus, and high levels of relatability and boredom. Lastly, when the base state, characterized as a transition hub between states (Song et al., 2022) occurred, participants rated high levels of curiosity and importance and low relatability. Our results show that latent brain state occurrence tracks subjective experience, providing insight into how latent state activity is related to conscious experience.

Boltzmann approach to the spin Hall effect revisited and electric field modified collision integrals

description: The intrinsic contribution to the spin Hall effect in a 2DEG with non-magnetic impurities is studied in a quantum Boltzmann approach. It is shown that if the steady state response is perturbative in the spin-orbit coupling parameter $λ$, then the precession term--vital for Dyakonov-Perel relaxation and the key to the spin Hall effect in previous similar Boltzmann studies--must be left out to first order in spin-orbit coupling. In such a case one would have that to lowest order in the parameters electric field, spin-orbit coupling, impurity strength and impurity concentration there is no intrinsic contribution to the spin Hall effect, not only for a Rashba coupling but for a general spin-orbit coupling. To cover all possible lowest order terms we consider also electric field induced corrections to the collision integral in the Keldysh formalism. However, these corrections turn out to be of second order in $λ$. For comparison we derive some familiar results in the case when the response is not assumed to be perturbative in $λ$. We also include a detailed discussion of why a relaxation time approximation of the collision integral fails. Finally we make a comment on pseudospin currents in bilayer graphene.
description: 15 pages, 1 table. The second version was extended with a summarizing table, a section on the relaxation time approximation and a comment on pseudospin currents in bilayer graphene

Antiferromagnetic Order of Repulsively Interacting Fermions on Optical lattices

description: The Néel state in fermionic mixtures of two pseudospin species in an optical lattice is analyzed at low temperatures. Experimentally it remains a challenge to demonstrate antiferromagnetic correlations in ultracold fermionic quantum gases. We find that, while in balanced systems the Néel order parameter can point in any spatial direction, in imbalanced mixtures antiferromagnetism is strictly perpendicular to the quantization axis (i.e., the z-axis). Since, experimentally, one always has to assume some minimal imbalance this should have important consequences for ongoing experiments.
