description: We determine the parton distribution functions (PDFs) in a next-to-next-to-leading order (NNLO) QCD-analysis of the inclusive neutral-current deep-inelastic-scattering (DIS) world data combined with the neutri{-}no-nucleon DIS di-muon data and the fixed-target Drell-Yan data. The PDF-evolution is performed in the $N_f = 3$ fixed-flavor scheme and supplementary sets of PDFs in the 4- and 5-flavor schemes are derived from the results in the 3-flavor scheme using matching conditions. The charm-quark DIS contribution is calculated in a general-mass variable-flavor-number (GMVFN) scheme interpolating between the zero-mass 4-flavor scheme at asymptotically large values of momentum transfer $Q^2$ and the 3-flavor scheme prescription of Buza-Matiounine-Smith-van Neerven (BMSN) at the value of $Q^2 = m_c^2$. The results in the GMVFN scheme are compared with those of the fixed-flavor scheme and other prescriptions used in global fits of PDFs. The strong coupling constant is measured at an accuracy of $\approx 1.5%$. We obtain at NNLO $α_s(M_Z^2) = 0.1135 \pm 0.0014$ in the fixed-flavor scheme and $α_s(M_Z^2) = 0.1129 \pm 0.0applying the BMSN-prescription. The implications for important standard candle and hard scattering processes at hadron colliders are illustrated. Predictions for cross sections of $W^{\pm}$- and $Z$-boson, the top-quark pair- and Higgs-boson production at the Tevatron and the LHC based on the 5-flavor PDFs of the present analysis are provided.014$

description: The electronic ground state in high-$T_{\rm c}$ cuprates where the superconducting state is suppressed by Ni substitution has been investigated in La$_{2-x}$Sr$_x$Cu$_{1-y}$Ni$_y$O$_4$ from the specific heat and muon spin relaxation measurements. It has been found that the ground state changes from a magnetically ordered state with the strong hole-trapping by Ni to a metallic state with the Kondo effect of Ni with increasing hole-concentration. Moreover, the analysis of the results has revealed that a phase separation into the magnetically ordered phase and the metallic phase occurs around the boundary of two phases.

description: We argue that the ratio of $ϕ$ mesons multiplicity over cube of the mean $p_T$ is proportional to the degeneracy of the medium produced in ultra-relativistic heavy ion collisions. The ratio extracted from the existing $ϕ$ meson data in the energy range $\sqrt{s}$=6.3-200 GeV, indicate that beyond a threshold energy $\sqrt{s}_{th}=15.74\pm 8.10$ GeV, the medium crosses over from a confined phase to a deconfined phase.

description: In this paper we study the geometry of the moduli space of (non-strongly) parabolic Higgs bundles over a Riemann surface with marked points. We show that this space possesses a Poisson structure, extending the one on the dual of an Atiyah algebroid over the moduli space of parabolic vector bundles. By considering the case of full flags, we get a Grothendieck-Springer resolution for all other flag types, in particular for the moduli spaces of twisted Higgs bundles, as studied by Markman and Bottacin and used in the recent work of Laumon-Ngô. We discuss the Hitchin system, and demonstrate that all these moduli spaces are integrable systems in the Poisson sense.

description: We report the discovery of a young, 0.16" binary, 2M2234+4041AB, found as the result of a Keck laser guide star adaptive optics imaging survey of young field ultracool dwarfs. Spatially resolved near-infrared photometry and spectroscopy indicate that the luminosity and temperature ratios of the system are near unity. From optical and near-infrared spectroscopy, we determine a composite spectral type of M6 for the system. Gravity-sensitive spectral features in the spectra of 2M2234+4041AB are best matched to those of young objects (~1 Myr old). A comparison of the Teff and age of 2M2234+4041AB to evolutionary models indicates the mass of each component is 0.10 (+0.075-0.04) Msun. Emission lines of H alpha in the composite optical spectrum of the system and Br gamma in spatially resolved near-IR spectra of the two components indicate that the system is actively accreting. Both components of the system have IR excesses, indicating that they both harbor circumstellar disks. Though 2M2234+4041AB was originally identified as a young field dwarf, it lies 1.5' from the well-studied Herbig Ae/Be star, LkHa 233. The distance to LkHa 233 is typically assumed to be 880 pc. It is unlikely 2M2234+4041AB could be this distant, as it would then be more luminous than any known Taurus objects of similar spectral type. We re-evaluate the distance to the LkHa 233 group and find a value of 325 (+72-50) pc, based on the Hipparcos distance to a nearby B3-type group member (HD 213976). 2M2234+4041AB is the first low-mass star to be potentially associated with the LkHa 233 group. At a distance of 325 pc, its projected physical separation is 51 AU, making it one of a growing number of wide, low-mass binaries found in young star-forming regions.

description: Annealing undoped MgB2 wires under high isostatic pressure (HIP) increases transport critical current density (Jtc) by 10% at 4.2 K in range magnetic fields from 4 T to 12 T and significantly increases Jtc by 25% in range magnetic fields from 2 T to 4 T and does not increase Jtc above 4 T at 20 K. Further research shows that a large amount of 10% SiC admixture and thermal treatment under a high isostatic pressure of 1 GPa significantly increases the Jtc by 40% at 4.2 K in magnetic fields above 6 T and reduces Jtc by one order at 20 K in MgB2 wires. Additionally, our research showed that heat treatment under high isostatic pressure is more evident in wires with smaller diameters, as it greatly increases the density of MgB2 material and the number of connections between grains compared to MgB2 wires with larger diameters, but only during the Mg solid-state reaction. In addition, our study indicates that smaller wire diameters and high isostatic pressure do not lead to a higher density of MgB2 material and more connections between grains during the liquid-state Mg reaction.

description: We analyze populations of Kuramoto oscillators with a particular distribution of natural frequencies. Inspired by networks where there are two groups of nodes with opposite behaviors, as for instance in power-grids where energy is either generated or consumed at different locations, we assume that the frequencies can take only two different values. Correlations between the value of the frequency of a given node and its topological localization are considered in both regular and random topologies. Synchronization is enhanced when nodes are surrounded by nodes of the opposite frequency. We find analytical estimations for the minimum value of the coupling strength between oscillators that guarantees the achievement of a globally synchronized state, getting a very good agreement with the numerical simulations.

An Apparent Induction of Secondary Dormancy in Eucalyptus globulus Labill Seeds
Creators: name: Nair, TS
Publisher: name: University Of Tasmania
Year: 2023

description: Eucalyptus globulus is a major plantation forestry species in southern Australia. Commercial E. globulus seedlots have high viability (95%) and uniform germination, which is completed within 5-6 days. However commercial nurseries have reported delays in germination with seedling emergence spread over five to ten weeks. According to growers and seed suppliers the problem is not restricted to particular seedlots and occurs in most nurseries. Observations have suggested that a brief period of desiccation or high temperature between sowing and germination may lead to the delays, but no clear cause has been established. Further, there is nothing in the literature to indicate either cause or possible management strategies. According to the ISTA guidelines the germination period of E. globulus is 5-14 days under laboratory conditions and in the field, germination should occur before 26 days. The aim of the present project was to establish the factors responsible for this apparent induction of previously unreported secondary dormancy in E. globulus seed and to provide a basis for commercial management of the problem.

description: Mid-latitude mesospheric summer echoes (MSEs) appear in radar observations during summer months. The geophysical factors controlling the formation of MSEs include solar and energetic particle ionisation, neutral temperature, turbulence, and meridional transport. A total of 12 years of summer months observations with the OSWIN (Ostsee-Wind) radar in Kühlungsborn, Germany, have been analysed to detect MSE events and to analyse statistical connections to these controlling factors. A more sensitive and consistent method for deriving signal-to-noise ratio has been utilised. Daily and monthly composite analysis demonstrates strong daytime preference and early summer seasonal preference for MSEs. The statistical results are not entirely conclusive due to the low-occurrence rates of MSEs. Nevertheless, it is demonstrated that the meridional transport from colder high-latitude summer mesosphere is the important controlling factor, while no clear connection to geomagnetic and solar activity is found. © 2019 Author(s).

The operations of risk : the meaning, emotion and morality of risk identities in social work practice
Creators: name: Stanford, Sonya
Publisher: name: University Of Tasmania
Year: 2023

description: This study explores how risk operates as a concept and practice in social workers' interventions. Concern has been expressed within the critical social work risk literature that risk operates as a morally conservative and repressive construct in social work practice within the context of neo-liberal risk society. This thesis explores whether the influence of risk is necessarily as totalising of our professional identities, and in turn our practices, as this literature would suggest. Thus the aim of the research has been to identify whether spaces exist within social workers' practice contexts that enable them to resist invitations into the moral conservatism of negative constructs of risk. My assumption has been that forearmed with this knowledge, as individual practitioners or collectively as a profession, we will have a greater capacity to 'speak back' to the morally conservative ethos of risk that pervades welfare discourses in neo-liberal risk society. To progress the aim of the study, I have asked the question 'How are ideas about risk constituted and integrated into social workers' interventions?' I conducted my explorations of the operations of risk in social work by considering how risk was spoken of by practitioners within reflective accounts of interventions they had implemented that were significant to them. The results demonstrate that risk operated as a complex and discursively persuasive concept within their reflections on practice. Most significantly, risk operated as a powerful constituent of client and practitioner risk identities. Risk was integral to how practitioners recognised their clients and selves, evident in their ascription of highly moralised and emotionally constituted 'at risk' and 'a risk' identities. Given the presence of co-existing, multiple risk identities within a single intervention, practitioners faced a choice about which risk identities they would respond to ‚Äö- their clients and/or their own. In taking a stand for clients, practitioners' accounts indicate that the proclivity towards defensive and morally timid practice could be resisted. Contemplation of ethical, moral and value imperatives and the re-contextualisation of ideas about risk for clients and practitioners assisted social workers in this endeavour. The implications of this finding for social work knowledge, practice and education are discussed, alongside ideas for future research

Dynamical difference between the cD galaxy and the stellar diffuse component in simulated galaxy clusters

description: Member galaxies within galaxy clusters nowadays can be routinely identified in cosmological, hydrodynamical simulations using methods based on identifying self bound, locally over dense substructures. However, distinguishing the central galaxy from the stellar diffuse component within clusters is notoriously difficult, and in the center it is not even clear if two distinct stellar populations exist. Here, after subtracting all member galaxies, we use the velocity distribution of the remaining stars and detect two dynamically, well-distinct stellar components within simulated galaxy clusters. These differences in the dynamics can be used to apply an un-binding procedure which leads to a spatial separation of the two components into a cD and a diffuse stellar component (DSC). Applying our new algorithm to a cosmological, hydrodynamical simulation we find that -- in line with previous studies -- these two components have clearly distinguished spatial and velocity distributions as well as different star formation histories. We show that the DSC fraction -- which can broadly be associated with the observed intra cluster light -- does not depend on the virial mass of the galaxy cluster and is much more sensitive to the formation history of the cluster. We conclude that the separation of the cD and the DSC in simulations, based on our dynamical criteria, is more physically motivated than current methods which depend on implicit assumptions on a length scale associated with the cD galaxy and therefore represent a step forward in understanding the different stellar components within galaxy clusters. Our results also show the importance of analyzing the dynamics of the DSC to characterize its properties and understand its origin.

description: We explore the relation of the Holst term with the Nieh-Yan term in terms of metric variables. We show that the Holst term indeed affects the classical equations of motion in the presence of matter with spin. Therefore the correct term to add to the Einstein-Hilbert action such that the equations of motion are not affected is the Nieh-Yan term. We then calculate the torsion charge due to this term in the context of a perfect fluid sphere with torsion and show that it vanishes once a horizon is formed but not otherwise. We also show that adding on torsion to General Relativity the Einstein's equations are no longer holographic in torsion although they continue to be so for the metric.

description: In binary aluminosilicate liquids and glasses, heterogeneity on intermediate length scale is a crucial factor for optical fiber performance, determining the lower limit of optical attenuation and Rayleigh scattering, but also clustering and precipitation of optically active dopants, for example, in the fabrication of high-power laser gain media. Here, we consider the low-frequency vibrational modes of such materials for assessing structural heterogeneity on molecular scale. We determine the vibrational density of states VDoS g(ω) using low-temperature heat capacity data. From correlation with low-frequency Raman spectroscopy, we obtain the Raman coupling coefficient. Both experiments allow for the extraction of the average dynamic correlation length as a function of alumina content. We find that this value decreases from about 3.9 nm to 3.3 nm when mildly increasing the alumina content from zero (vitreous silica) to 7 mol%. At the same time, the average inter-particle distance increases slightly due to the presence of oxygen tricluster species. In accordance with Loewensteinian dynamics, this proves that mild alumina doping increases structural homogeneity on molecular scale.

In 1997 Murakami and Ohtsuki [MO] first constructed such an extension, building on Drinfel'd's theory of associators. We construct a step by step definition, using elementary Kontsevich integral methods, to get a one-parameter family of corrections that all yield invariants well behaved under the graph operations above.

Galena Creek Bridge Structural Health Monitoring Instrumentation and Modeling
Creators: name: Falkensammer, Leopold

description:  Structural health monitoring (SHM) of an instrumented structure provides numerous benefits when assessing the long-term condition of the structure against degradation, or the short-term condition after an extreme event, such as an earthquake. The Nevada Department of Transportation (NDOT) has an interest in expanding the use of SHM for such assessments. Accordingly, the objective of the current study is to develop and implement a permanent SHM system for the Galena Creek Bridge, the largest concrete cathedral arch bridge in the world, to monitor its response to routine traffic and seismic activity. Completed in 2012, the bridge connects Reno and Carson City, Nevada as part of Interstate 580 and US Route 395. The structure consists of twin 526-meter cast-in-place, reinforced concrete box-girder bridges. The research team takes a unique approach by implementing a software and SHM approach originally developed by the United States Geological Surveys National Strong Motion Project. The instrumentation will measure the structural response to traffic, wind, seismic, and thermal loadings. The system will automatically trigger on predefined events, such as an earthquake, and provide near real-time alerts in the form of text and email messages. In addition, a detailed finite element model of the structure was created and calibrated to establish the natural frequencies, mode shapes, and general dynamic response. The research helps improve the behavioral understanding of complex structures during seismic events. Ultimately, the project serves as an SHM testbed for NDOT, demonstrates a bridge application of the SHM software, and contributes to the advancement of SHM as a bridge safety and management tool.
Empirical Justification for Supportive Other Involvement in Collegiate Athletes Mental Health Intervention

description:  Student-athletes have been identified to evidence similar or higher rates of mental health difficulties and lower levels of mental health engagement as compared with non-athlete peers. Along these lines, sport-specific mental health intervention has been justified by researchers, yet only one randomized clinical trial has been conducted in collegiate student-athletes who have been formally assessed for mental health disorders (i.e., a family behavior therapy as compared with traditional campus counseling as usual; Donohue et al., 2018a). Results of this outcome study demonstrated greater improvements for participants who received the family-based intervention up to 8-months post-randomization. In this clinical trial, the potential influence of supportive others (i.e., family, coaches, teammates, intimate partners) on athletes mental health was not assessed for the family-based intervention. Participation of the supportive others varied based on the desire of athlete participants to include them and their availability; and occurred in-person, through telephone, and/or video-conference. In the proposed study, the association between supportive others participation in athletes family behavior therapy and mental health and sport performance outcomes was examined. As hypothesized, results indicated that the number of family behavior intervention sessions attended by athletes was significantly associated with factors that interfere with sport performance. The number of family behavior therapy sessions attended by supportive others with the athletes was not associated with intervention outcomes after the athletes attendance to family behavior sessions was considered. However, the number of supportive other types (family, coaches, teammates, intimate partners) involved throughout intervention was significantly correlated with mental health. These results suggest the number of supportive other types involved in athletes family behavior therapy, and not their cumulative session attendance to family sessions per se is most important to athletes mental health and sport performance.

description: The particular feature of this study is the investigation of effects of pure fluoride- or stannous ions based mouthrinses on the erosion protective properties and the ultrastructure of the in situ pellicle (12 volunteers). Experimental solutions were prepared either from 500 ppm NaF, SMFP, AmF or SnF 2 or 1563 ppm SnCl 2 , respectively. After 1 min of in situ pellicle formation on bovine enamel slabs, rinses with one of the preparations were performed for 1 min and intraoral specimens’ exposure was continued for 28 min. Native enamel slabs and rinses with bidestilled water served as controls. After oral exposure, slabs were incubated in HCl (pH 2; 2.3; 3) for 120 s and kinetics of calcium- and phosphate release were measured photometrically; representative samples were analysed by TEM and EDX. All mouthrinses reduced mineral loss compared to the native 30-min pellicle. The effect was pH-dependent and significant at all pH values only for the tin-containing mouthrinses. No significant differences were observed between the SnF 2 - and the SnCl 2 -containing solutions. TEM/EDX confirmed ultrastructural pellicle modifications. SnF 2 appears to be the most effective type of fluoride to prevent erosive enamel demineralisation. The observed effects primarily have to be attributed to the stannous ions’ content. © 2019, The Author(s).
Physiological changes in age which affect adult learning performance
Creators: name: Lund, Mary Macleod
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis was to review research on the developmental physiological processes of aging which have significance for adult learning. Attention was directed, specifically, to the progressive, age-related changes most immediately associated with the skills of communication: vision, audition, speech, reaction and movement times to visual and auditory stimuli, perception, retention, and performance facility. Affective reaction to physiological aging was also considered. In recognition of the interdisciplinary nature of the relationship of aging to learning, research from diverse areas was examined. Psychological inferences, in some instances, predominate since the study is concerned not with aging but with learning concomitant with the aging processes. References of recent date were normally consulted. Investigations have revealed no "typical adult" nor even a typical or an average progression in any aspect of physiological development; therefore, an individualized response to any adult learning situation can be expected. The evidence with the greatest impact for the education of adults lies in the areas of previous learning, recency of learning, and habits of learning. There are educational needs not now met by adult education; not the least of these is the need for understanding the processes involved in physiological aging. It is well categorized that older people can learn and under certain conditions do learn, but adults being different learners require a different social, educational, and physical environment in which to learn. The facilities at present provided for child-youth education and "adapted" for adults present some frustrating physical limitations for adult learners. Adults have distinctive needs for learning. Where these needs have been catered to, the measure of success has been high, the failure rate low. There is an awareness of the fallacy of setting arbitrary limits to successful achievement based solely on chronological divisions.
title: The Son is truly Son : the Trinitarian and christological theology of Eusebius of Caesarea
Creators: name: Renberg, Adam Robert
Publisher: name: University of St Andrews
Year: 2020

description: This project explores the theological framework of Eusebius of Caesarea, focusing specifically on his understanding of the Son of God. Therein, it proposes and utilizes a unique lens to view the bishop—according to his exegetical strategies and his explicitly theological works. In doing so, Eusebius’ primary understanding of the nature and role of the second person of the Trinity comes to the fore: the ‘Son is Truly Son.’ That is to say, biblical personalism dictates his understanding of the persons in the Godhead. This is discussed in several facets of his thought. First, the Son’s natural relation to the Father is seen to be both the distinguishing mark and the source of divine unity, according to Eusebius’ framework for the Trinity. Second, his cosmological system demonstrates Eusebius’ emphasis on the Son’s unique nature as the image of the invisible God, the only one able to reveal the apophatic Father to creation. Third, his soteriology emphasizes biblical personalism through Christ’s salvific work, as Christ is the teacher of the true religion and the Father—only the Son knows and is able to ‘image’ him. Finally, Eusebius’ theology of the incarnation emphasizes the unitive nature of Christ, in which the Son of God is likewise the Son of Man. Throughout, this project employs unique patristic interlocuters, underutilized Eusebian texts and paratextual devises, and the debate with Marcellus to demonstrate how his theological framework is within—and shapes—eastern theology, particularly from Origen to the Cappadocians. It also nuances and qualifies past assessments on some of Eusebius’ suspect theology, particularly on his eternal subordinationism and Christology. Throughout, it is apparent that Eusebius is an important transmitter of Origenian theology and a foundational thinker for the later fourth and early fifth century.
Rapid self-organised initiation of ad hoc sensor networks close above the percolation threshold

description: This work shows potentials for rapid self-organisation of sensor networks where nodes collaborate to relay messages to a common data collecting unit (sink node). The study problem is, in the sense of graph theory, to find a shortest path tree spanning a weighted graph. This is a well-studied problem where for example Dijkstra's algorithm provides a solution for non-negative edge weights. The present contribution shows by simulation examples that simple modifications of known distributed approaches here can provide significant improvements in performance. Phase transition phenomena, which are known to take place in networks close to percolation thresholds, may explain these observations. An initial method, which here serves as reference, assumes the sink node starts organisation of the network (tree) by transmitting a control message advertising its availability for its neighbours. These neighbours then advertise their current cost estimate for routing a message to the sink. A node which in this way receives a message implying an improved route to the sink, advertises its new finding and remembers which neighbouring node the message came from. This activity proceeds until there are no more improvements to advertise to neighbours. The result is a tree network for cost effective transmission of messages to the sink (root). This distributed approach has potential for simple improvements which are of interest when minimisation of storage and communication of network information are a concern. Fast organisation of the network takes place when the number $k$ of connections for each node ({\em degree}) is close above its critical value for global network percolation and at the same time there is a threshold for the nodes to decide to advertise network route updates.
