description: We consider the phonon contribution to the bulk viscosities $ζ_1, ζ_2$ and $ζ_3$ of a cold relativistic superfluid. We assume the low temperature $T$ regime and that the transport properties of the system are dominated by the phonons. We use kinetic theory in the relaxation time approximation and the low energy effective field theory of the corresponding system. The parametric dependence of the bulk viscosity coefficients is fixed once the equation of state is specified, and the phonon dispersion law to cubic order in momentum is known. We first present a general discussion, valid for any superfluid, then we focus on the color-flavor locked superfluid because all the parameters needed in the analysis can be computed in the high density limit of QCD, and also because of the possible astrophysical applications. For the three independent bulk viscosity coefficients we find that they scale with the temperature as $ζ_i \sim 1/T$, and that in the conformal limit only the third coefficient $ζ_3$ is non-zero.

title: Testing Mediated Effects of a Sex Education Program on Youth Sexual Activity
Creators: name: Birch, Paul James
Publisher: name: Utah State University
Year: 2011

description: Empirical investigations have identified hundreds of factors that predict whether youth engage in sexual activity (YSA). To promote optimal health and the avoidance of unhealthy or problematic outcomes that can result from YSA, sex education programs have been extensively developed and evaluated. Many evaluations have identified the effect of the program on immediate outcomes such as attitudes and intentions, others have examined subsequent behavioral and health outcomes, and some have done both. The purpose of this study was to extend the evaluation literature by testing a mediated effects model. A sex education program was found to have significant immediate effects on several attitudinal factors that have been shown to predict YSA, and was shown to significantly reduce the incidence of sexual activity approximately one year after the program (OR = 0.534, p = .004). A mediating effects test showed that youth’s stated intentions to engage in sexual activity was a significant mediated effect (B = -0.182, Lower CI = -0.291, Upper CI = -0.073), suggesting that the program effects on sexual activity occurred through the immediate effect on intentions, which in turn was likely affected by program content, which changed other attitudinal factors such as values, efficacy, and knowledge. Using immediate changes on these mediating factors to predict the likelihood of YSA showed that accurate prediction was possible, with an overall prediction accuracy rate of 74%. It was easier to predict who was not going to engage in YSA (94% accuracy) than who would (35% accuracy). Further predictive analyses showed that a score of 4.12 (on a scale of 1 to 5) on agreement with the items comprising the mediating factors’ scales was a threshold point, with the likelihood of engaging in YSA rising sharply as a function of this score until that point, and score increases above that point resulting in minimal changes in the probability of YSA. The results of this study demonstrate that it is possible to reduce YSA, that intent to engage in YSA was a primary mediator, and that accurate prediction of eventual behavioral results is possible, based on analysis of immediate results.

description: Design of a doubly-clamped beam structure capable of localizing mechanical and optical energy at the nanoscale is presented. The optical design is based upon photonic crystal concepts in which patterning of a nanoscale-cross-section beam can result in strong optical localization to an effective optical mode volume of 0.2 cubic wavelengths ((λ_{c})^3). By placing two identical nanobeams within the near field of each other, strong optomechanical coupling can be realized for differential motion between the beams. Current designs for thin film silicon nitride beams at a wavelength of 1.5 microns indicate that such structures can simultaneously realize an optical Q-factor of 7x10^6, motional mass m~40 picograms, mechanical mode frequency ~170 MHz, and an optomechanical coupling factor (g_{OM}=dω_{c}/dx = ω_{c}/L_{OM}) with effective length L_{OM} ~ λ= 1.5 microns.

title: The Paradox of Uranium Development: A Polanyian Analysis of Social Movements Surrounding the Piñon Ridge Uranium Mill
Creators: name: Malin, Stephanie Ann
Publisher: name: Utah State University
Year: 2011

description: Renewal of nuclear energy development has been proposed as one viable solution for reducing greenhouse gas emissions and impacts of climate change. This discussion became concrete as the first uranium mill proposed since the end of the Cold War, the Piñon Ridge Uranium Mill, received state permits in January 2011 to process uranium in southwest Colorado’s Paradox Valley. Though environmental contamination from previous uranium activity caused one local community to be bulldozed to the ground, local support for renewed uranium activity emerges among local residents in communities like Nucla, Naturita, and Bedrock, Colorado. Regionally, however, a coalition of organized, oppositionbased grassroots groups fights the decision to permit the mill. Combined, these events allow social scientists a natural laboratory through which to view social repercussions of nuclear energy development.
In this dissertation, I use a Polanyian theoretical framework to analyze social, political-economic, and environmental contexts of social movements surrounding PR Mill. My overarching research problem is: How might Polanyian double movement theory be applied to and made empirically testable within the social and environmental context of uranium development? I intended this analysis to inform energy policy debates regarding renewable energy. In Chapter 1, I found various forms of social dislocation lead to two divergent social movement outcomes. Economic social dislocation led to strong mill support among most local residents, according to archival, in-depth interview, and survey data. On the other hand, residents in regional communities experienced two other types of social dislocation – another kind of economic dislocation, related to concern over boombust economies, and environmental health dislocations related to uranium exposure, creating conditions for a regional movement in opposition to PR Mill. In Chapter 2, I focus on regulations and find that two divergent social movements – a support movement locally and a countermovement against the mill regionally – emerge also as a result of strong faith in regulations, regulators, and Energy Fuels countered by marked distrust in regulations, regulators, and Energy Fuels, respectively. In Chapter 3, I advance Polanyi’s double movement theory by comparing different emergent social movements surrounding uranium, showing that historically different circumstances surrounding uranium can help create conditions for divergent social movements.
W- and Z-boson production with a massive bottom-quark pair at the Large Hadron Collider

description: We present total and differential cross sections for W b anti-b and Z b anti-b production at the CERN Large Hadron Collider with a center-of-mass energy of 14 TeV, including Next-to-Leading Order (NLO) QCD corrections and full bottom-quark mass effects. We also provide numerical results obtained with a center-of-mass energy of 10 TeV. We study the scale uncertainty of the total cross sections due to the residual renormalization- and factorization-scale dependence of the truncated perturbative series. While in the case of Z b anti-b production the scale uncertainty of the total cross section is reduced by NLO QCD corrections, the W b anti-b production process at NLO in QCD still suffers from large scale uncertainties, in particular in the inclusive case. We also perform a detailed comparison with a calculation that considers massless bottom quarks, as implemented in the Monte Carlo program MCFM. The effects of a non-zero bottom-quark mass (m_b) cannot be neglected in phase-space regions where the relevant kinematic observable, such as the transverse momentum of the bottom quarks or the invariant mass of the bottom-quark pair, are of the order of m_b. The effects on the total production cross sections are usually smaller than the residual scale uncertainty at NLO in QCD.

description: Ultrasonic welding (UW), as a solid-state joining process, uses an ultrasonic energy source (usually with a frequency of 20 kHz or above) to induce oscillating shears between the faying surfaces to produce metallurgical bonds between a wide range of metal sheets [1, 2], thin foils [3], semiconductors [4], plastics [5], glass [6], and ceramics [7]. In contrast to traditional fusion welding processes, ultrasonic welding has several inherent advantages [3,8] derived from its solid-state process characteristics, and has been in use as a versatile joining method in the electronics, automotive, and aerospace industries since the 1950s

They occur only through higher order diagrams, and new particles contributions can provide a significant enhancements, which would be an uniquevocal signs of physics beyond the Standard Model. In this paper we present the most recent measurements on FCNC processes performed by CDF and D0 Collaborations, while last section is devote to the charm physics at CDF.

description: Axonal injury and loss of white matter has been well documented in corpus callosum (CC) of patients with multiple sclerosis (MS), an inflammatory demyelinating disorder of the of Central Nervous System (CNS). The CC is the largest compact white matter fiber bundle of the brain connecting the two cerebral hemispheres. It seems that CC continue to mature structurally from infancy to adulthood (Muetzel RL, 2008). The topographical organization of its fibers allows the association of its abnormalities with those of specific cortical regions. It is one of the few white matter tracts that can be adequately evaluated by conventional Magnetic Resonance Imaging (MRI), having sharply demarcated two-dimensional limits on a mid-saggital T1W imaging (Fiqueira FF, 2007). So, as a consequence of these anatomic characteristics, it is reasonable to assume that CC morphometrics might be used as a possible marker for the analysis of its integrity. Conventional and non-conventional MRI techniques have been used to characterize pathological damages of the CC; for instance, diffusion tensor imaging (DTI) can show white matter changes undetected by conventional MRI (Bester M, 2008). We carried out a review focusing our interest on the diagnostic efficacy of MRI to predict MS disability. PubMed search engine was used to select manuscripts with predefined search terms: “corpus callosum”, “multiple sclerosis”, “disability” and “magnetic resonance imaging”. Only manuscripts in English language, published from January 2003 to January 2013, were selected. Abstracts and unpublished studies were excluded. References of all relevant retrieved articles, of review articles, were also evaluated manually in order to find additional articles. For data extraction an electronic form was prepared. The findings of the review suggest that CC atrophy is a more sensitive marker of disease activity than the global atrophy measures, predicting clinically definite multiple sclerosis (CDMS)conversion as early as 6 months of clinically isolated syndrome (CIS) (Kalincik T, 2012). Furthermore, the occurrence or growth of lesions over the first year in the splenium of corpus callosum, together with the cerebellum and the thalamus, was associated with cognitive worsening at year 5. CC atrophy seems to be a simple and an accurate predictor of disability, mostly for secondary progressive MS (Fiqueira FF, 2007), and it seems helpful for routine clinical activities (Vaneckova M, 2012).

Redshift space correlations and scale-dependent stochastic biasing of density peaks

description: We calculate the redshift space correlation function and the power spectrum of density peaks of a Gaussian random field. In the linear regime k < 0.1 h/Mpc, the redshift space power spectrum is P^s_{pk}(k,u) = exp(-f^2 s_{vel}^2 k^2 u^2) * [b_{pk}(k) + b_{vel}(k) f u^2]^2 * P_m(k), where u is the angle with respect to the line of sight, s_{vel} is the one-dimensional velocity dispersion, f is the growth rate, and b_{pk}(k) and b_{vel}(k) are k-dependent linear spatial and velocity bias factors. For peaks, the value of s_{vel} depends upon the functional form of b_{vel}. The peaks model is remarkable because it has unbiased velocities -- peak motions are driven by dark matter flows -- but, in order to achieve this, b_{vel} is k-dependent. We speculate that this is true in general: k-dependence of the spatial bias will lead to k-dependence of b_{vel} even if the biased tracers flow with the dark matter. Because of the k-dependence of the linear bias parameters, standard manipulations applied to the peak model will lead to k-dependent estimates of the growth factor that could erroneously be interpreted as a signature of modified dark energy or gravity. We use the Fisher formalism to show that the constraint on the growth rate f is degraded by a factor of two if one allows for a k-dependent velocity bias of the peak type. We discuss a simple estimate of nonlinear evolution and illustrate the effect of the peak bias on the redshift space multipoles. For k < 0.1 h/Mpc, the peak bias is deterministic but k-dependent, so the configuration space bias is stochastic and scale dependent, both in real and redshift space. We provide expressions for this stochasticity and its evolution (abridged).

description: In the course of certain research work it became necessary to measure the specific heat of liquid cis and trans decahydrate with great accuracy; The ordinary Williams and Danielle adiabatic calorimeter was found to be impractical* Several years ago a calorimeter for measuring the specific heat of liquid hydrocarbons near room temperatures was developed at the U.S. Bureau of Standards, A study of this instrument proved that it would be the type desirable for the above measurement. Plans were obtained and altered to suit not only the measurements for cis and trans decalin but such hydrocarbons as are solid at room temperatures. During the past year such a calorimeter was constructed. It has also been so altered as to permit measurements of the latent heat of fusion to be made with 1 part in 1000.

description: We discuss the Mordell-Weil sieve as a general technique for proving results concerning rational points on a given curve. In the special case of curves of genus 2, we describe quite explicitly how the relevant local information can be obtained if one does not want to restrict to mod p information at primes of good reduction. We describe our implementation of the Mordell-Weil sieve algorithm and discuss its efficiency.

Effect of stress on electrolytic solution potential
Creators: name: McDonnell, Basil
Publisher: name: University of British Columbia
Year: 2012

description: Uni-directional stresses have been applied, to copper wires, and the potential difference between such wires and unstressed wires determined in various electrolytes. The potential differences have been determined both by a galvanometer method and potentiometrically. The latter method gave more consistent results and is thought to eliminate some of the possibilities of polarization. Some correlation has been found between the amount of applied stress and the potential difference observed, and thermodynamic arguments have been advanced to explain such results, at least qualitatively. A correlation of these same results with time has led to the conclusion that the potential difference is essentially due to a surface effect.

description: In pulmonary fibrosis, the usual interstitial pneumonia (UIP) pattern is characterised by heterogeneous, patchy fibrosis, with areas of normal lung adjacent to areas of complete destruction (honeycombing) and by fibroblastic foci (FF). The NSIP pattern which is characteristic of systemic sclerosis, is characterised by a more homogeneous involvement of the lung without honeycombing and FF. Little is known on lymphatic vessels in lung fibrosis. Defective lymphatic clearance could lead to prolonged exposure to pathogenic antigens and/or pro-inflammatory/pro-fibrotic mediators. We evaluated the distribution and morphology of lymphatic vessels in lung biopsies of 6 patients with UIP, 6 NSIP and 5 controls. Consecutive sections were stained with Movat’s pentachrome and with double immunostaining for von Willebrand factor and podoplanin (D2-40). Area, perimeter and position were recorded for vessels with a diameter > 5µm. We investigated separately in lintralobular, sub-pleural, and interlobular spaces. Lymphatics were consistently larger in subpleural spaces and in interlobular septa than in intralobular tissue. In the latter, the density of lymphatic vessels was significantly reduced in NSIP and in UIP (both 21±1 mm-2) compared to controls (35±4 mm-2) . In controls, 85±6% of the intralobular lymphatics were close (< 100 µm) to a blood vessel, and only 5±4% were in the proximity of bronchoalveolar spaces, while in the disease groups they were less frequently perivascular (NSIP 55 ±3%, UIP 56 ±2%) and more frequently associated with the bronchoalveolar lumen (NSIP 85 ±3%, UIP 69 ±2%). By contrast, in interlobular septa, lymphatic density was significantly increased in NSIP (303±28 mm-2) and in UIP (286±124 mm-2) compared to controls (96±69 mm-2). No differences in lymphatic density was seen in subpleural spaces. Thus, our data show a marked redistribution of lymphatic vessels within the lung in pulmonary fibrosis, without noticeable differences between the NSIP and UIP patterns.

title: The Effect of Direct Instruction in Teaching Addition and Subtraction of Decimals and Decimal Word Problems on Students At Risk for Academic Failure
Creators: name: Small, Heather Hoopes
Publisher: name: Utah State University
Year: 2011

description: This study investigated the effects of a direct instruction program on the ability of elementary school students identified as at risk for math failure to add and subtract numbers with decimals, and complete addition and subtraction word problems with decimals. Direct instruction has previously been shown to increase the math skills of special education and general education students. This study examined the extent to which these students could master these skills in six hours of instruction, with carefully designed sequences of examples and strategy instruction in word problems. The study took place in two elementary schools. The participants were fifth grade students who had received low math scores on a school wide test and placed in a math group accordingly. The students were given a pretest and placed into two different groups, iv based on a stratified random process. The students in the treatment group received six lessons in decimals and word problems. After the six lessons, the groups were given a posttest. Student progress was assessed by comparing the groups on posttest results, comparing the students’ pretest and posttest scores, and using the ANOVA to determine statistical significance. On the posttest, the students in the treatment group scored 35 percentage points higher than the students in the control group – this difference was statistically significant. The increase was largest in their ability to add and subtract decimals, however many of the students also made considerable progress in their ability to solve word problems.

Come un tamburo, quando il nostro pianeta trema a causa di un terremoto emette onde gravito-acustiche che si propagano e generano perturbazioni atmosferiche misurabili. Tali segnali sono stati rivelati dal satellite italo-cinese Cses-01, che passava sopra l’epicentro del terremoto del 5 agosto 2018 a Bayan, Indonesia, sei ore prima e al momento della scossa. Un nuovo modello analitico tutto italiano e unico nel suo genere è stato sviluppato allo scopo di associare le misure satellitari all’attività sismica e migliorare la comprensione dei fenomeni precursori dei terremoti. Lo studio è stato appena pubblicato sulla rivista Remote Sensing Mdpi. Media Inaf ha intervistato il primo autore, Mirko Piersanti dell’Infn

title: Ecologically-Based Manipulation Practices for Managing Bromus tectorum-infested Rangelands
Creators: name: Fowers, Beth
Publisher: name: Utah State University
Year: 2011

description: Cheatgrass (Bromus tectorum) is an invasive annual grass common in several semiarid plant communities in the western U.S. B. tectorum presence increases fire frequency and size, reducing species diversity, and leading to annual species-dominated systems with inconsistent livestock forage potential and degraded wildlife habitat value. Most efforts to manage B. tectorum-dominated rangelands have focused on controlling the plant itself rather than addressing the causes of vegetation change. An alternative approach, ecologically-based invasive plant management (EBIPM), identifies treatments that can alter factors associated with the causes of succession, leading to a more desirable vegetation state. This study utilized the EBIPM framework to design a large-scale demonstration project, which implemented a series of manipulation treatments (mowing, prescribed fire, imazapic herbicide, and seeding with perennial species) to suppress B. tectorum and promote desirable species. The treatments were implemented at two semiarid shrubland sites in northwestern Utah. Treatments were evaluated by measuring resident vegetation cover, density, aboveground biomass, and litter and soil seed banks. Herbicide was most effective in reducing B. tectorum cover, density, and biomass, while fire was effective in reducing seed density in the litter seed bank. Treatment interactions were rarely significant; however, by combining fire and herbicide, increased B. tectorum control was achieved. Seedlings of seeded perennial grasses emerged in all treatments; however, establishment by the end of the first growing season was greatest in treatments involving fire. The results of this study indicate that using a decision-making framework to select a series of treatments that alter the causes of succession can improve the management of B. tectroum-dominated rangelands.

description: Adult skeletal muscle cells are multinucleated syncytia with a peculiar cytoskeletal apparatus, relatively resistant to apoptosis but susceptible to atrophy when catabolic inputs exceed. Among molecular mechanisms involved in muscle atrophy induced in vitro by cisplatin (CisPt), a widely used chemotherapic drug, dysfunctional autophagy emerged as an important contributing factor. Macroautophagy is a physiological process, necessary in skeletal muscles to clear abnormal proteins and organelles, mainly mitochondria, and to maintain an efficient mass (Sandri, 2011). Here we sought to morphologically characterize macroautophagy in vitro in C2C12 myotubes, at 5 days of differentiation, exposed to CisPt from 4h up to 24h, and its dependence on tubulin cytoskeleton. Furthermore we tested taurine, a 2-aminoethanesulfonic acid, previously beneficial in CisPt exposed renal cells (Rovetta et al., 2012). Confocal, transmission and scanning electron microscopy were adopted to solve these points. Main findings were that 10-50 microM CisPt stimulated macroautophagy very early in myotubes but it persisted even at 24h, when autophagolysosomes increased and LC3-positive puncta accumulated beneath sarcolemma. At this time, nucleolar segregation, mitochondria damage, disaligned myotubes and sarcolemma blebbings were observed. Taurine plus 50 microM CisPt reduced autophagolysosomes density, ameliorated mitochondria and rescued atrophy. We suggest that taurine, by modulating proper autophagy, might be considered a reliable strategy to control muscle wasting.

description: The polar condensation/sublimation of CO2, that involve about one fourth of the atmosphere mass, is the major Martian climatic cycle. Early observations in visible and thermal infrared have shown that the sublimation of the Seasonal South Polar Cap (SSPC) is not symmetric around the geographic South Pole. Here we use observations by OMEGA/Mars Express in the near-infrared to detect unambiguously the presence of CO2 at the surface, and to estimate albedo. Second, we estimate the sublimation of CO2 released in the atmosphere and show that there is a two-step process. From Ls=180° to 220°, the sublimation is nearly symmetric with a slight advantage for the cryptic region. After Ls=220° the anti-cryptic region sublimation is stronger. Those two phases are not balanced such that there is 22% +/- 9 more mass the anti-cryptic region, arguing for more snow precipitation. We compare those results with the MOLA height measurements. Finally we discuss implications for the Martian atmosphere about general circulation and gas tracers, e.g. Ar.
