description: Along with $π^0$ and η mesons, a resonance structure in the invariant mass spectrum of two photons at Mγγ = 360 \pm 7 \pm 9 MeV is observed in the reaction d + C \rightarrow γ + γ + X at momentum 2.75 GeV/c per nucleon. Estimates of its width and production cross section are Γ = 64 \pm 18 MeV and $σ_{γγ}$ = 98 \pm 24 μb, respectively. The collected statistics amount to 2339 \pm 340 events of 1.5 \cdot 10^6 triggered interactions of a total number ~ 10^12 of dC-interactions. The results on observation of the resonance in the invariant mass spectra of two $π^0$ mesons are presented: the data obtained in the d + C \rightarrow γ + γ reaction is confirmed by the d + C \rightarrow $π^0$ + $π^0$ reaction: $M_{π^0π^0}$ = 359.2 \pm 1.9 MeV, Γ = 48.9 \pm 4.9 MeV; the ratio of Br(R\rightarrowγγ) / Br(R\rightarrow$π^0π^0$) = (1.8 ÷ 3.7)\cdot10^-3.

Delineation of site chronology and spatial components using macroscopic lithic analysis at DhRp-52
Creators: name: Wilkerson, Emily Ann
Publisher: name: University of British Columbia
Year: 2010

description: This thesis summarizes the results of an analysis of stone tools from site DhRp-52 to determine differences and similarities between its spatial and temporal components. DhRp-52 was an inland/riverine settlement that spanned approximately 2,500 years of occupational history contemporaneous with the Old Cordilleran Culture to the Locarno Beach Phase. My research analyzed stone tools to distinguish site components and structural features through time and in space, assessed similarities and differences between structures and their associated non-structural areas, evaluated the presence of three temporal components at the site, interpreted site use through assemblage structure variation, and attempted to understand how the site fit within the regional chronology. These analyses demonstrated that in most cases, stone tool assemblages reflected differences between site components through time (stratigraphy) and space (inside and outside structures). Statistically significant differences were detected between the structural and non-structural zones in the most recent and upper-most component of the site and between the three temporal components, but not in the middle component between non-structural and structural zones. These findings suggested two conclusions: 1) spatial partitioning was more prominent in the Late Component than the Middle Component, and 2) three occupational components identified by stratigraphy and radiocarbon dates were substantiated by tool assemblage variation. A comparison between DhRp-52’s three temporal components and the Glenrose Cannery and Crescent Beach sites determined that although major hallmarks of lithic technological change relating to regional chronology were observed at both sites and their respective components, DhRp-52’s temporal deposits cannot be assigned to the Old Cordilleran Culture, Charles Culture or Locarno Beach Phase at this time. This research at DhRp-52 contributes to the overall understanding of early human settlement in the lower Fraser River Valley and to our understanding of regional chronology. It suggests how resources other than intensive salmon harvesting may have facilitated early intensive settlement in the region, monitors lithic technological change through time in the Fraser River Valley, and how lithic assemblage composition can vary at different locations within the Gulf of Georgia region.

description: We present high-resolution I-band imaging of the core of the globular cluster M15 obtained at the 2.5 m Nordic Optical Telescope with FastCam, a low readout noise L3CCD based instrument. Short exposure times (30 ms) were used to record 200000 images (512 x 512 pixels each) over a period of 2 hours 43 min. The lucky imaging technique was then applied to generate a final image of the cluster centre with FWHM ~ 0".1 and 13" x 13" FoV. We obtained a catalogue of objects in this region with a limiting magnitude of I=19.5. I-band photometry and astrometry are reported for 1181 stars. This is the deepest I-band observation of the M15 core at this spatial resolution. Simulations show that crowding is limiting the completeness of the catalogue. At shorter wavelengths, a similar number of objects has been reported using HST/WFPC observations of the same field. The cross-match with the available HST catalogues allowed us to produce colour-magnitude diagrams where we identify new Blue Straggler star candidates and previously known stars of this class.

description: Both theory and research stress that many intersecting factors influence not only how parents care for their children, but also how optimal care of children is socially constructed. An often-overlooked factor that impacts the welfare of children is gender inequality. This three-article dissertation focuses on child welfare, parenting, and gender before and during the early Covid-19 pandemic, which was a period when inequality broadly, including gender inequality, was more exposed. The first two articles for the dissertation were drawn from a study that explored parenting stress, behaviors, and ideologies during the early phase of the Covid-19 pandemic. Quantitative and qualitative data for this study (N = 720) were collected in two waves from Midwestern American mothers of young children in spring 2020. The first of these articles finds that negative Covid-related impacts on the household were positively associated with parenting stress, but also that parenting stress fully mediated the weak relationship between these impacts and maltreatment-related behavior. In the second article I examine the open-ended text responses from the survey to explore how mothers understood their own experiences of the pandemic lockdown. I find that mothers drew on idealized mothering ideology in anxiety-focused ways that shaped their experiences of extreme fatigue, loss of patience, and harm. These studies highlight how parenting stress – which occurs when parenting demands exceed resources – was constituted as a gendered phenomena in the early pandemic. In addition to negatively constructing outcomes for mothers, the gender structure also negatively shapes outcomes for boys. Using population-level underlying cause of death mortality microdata for 2000-2020, I show that mortality disadvantages for boys in early childhood are socially shaped, with boys more likely to die of injury-related causes where supervision is a contributing factor. Unlike others who have argued that the excess injury deaths of boys are driven by biological differences, I argue that a gendered supervision context likely accounts for some of mortality differences in early childhood. Implications for the articles’ findings are numerous, including that additional theory building and empirical research is needed.

description: This map shows the locations and status, as at 31 December 2022, of Australian operating mines, mines under development, mines on care and maintenance and resource deposits associated with critical minerals. Developing mines are deposits where the project has a positive feasibility study, development has commenced or all approvals have been received. Mines under care and maintenance and resource deposits are based on known resource estimations and may produce critical minerals in the future. The critical mineral deposits on this map may not be comprehensive for all commodities. For the purposes of this map, critical minerals are defined as minerals and elements (solid and gaseous) that are vital for modern technology and whose supply may be at risk of disruption. The Australian critical minerals list comprises aluminium (high-purity alumina), antimony, beryllium, bismuth, chromium, cobalt, gallium, germanium, graphite, hafnium, helium, indium, lithium, magnesium, niobium, platinum group elements, rare earth elements, rhenium, scandium, silicon (high-purity silica), tantalum, titanium, tungsten, vanadium and zirconium. These commodities are coloured by mineral groupings on the map.

description: We study models where the superpartners of the ordinary particles have continuous spectra rather than being discrete states, which can occur when the supersymmetric standard model is coupled to an approximately conformal sector. We show that when superpartners that are well into the continuum are produced at a collider they tend to have long decay chains that step their way down through the continuum, emitting many fairly soft standard model particles along the way, with a roughly spherical energy distribution in the center of mass frame.

description: Hemocyanin is an extracellular respiratory protein containing copper in hemolymph of invertebrates, such as Mollusk and Arthropod. Keyhole limpet hemocyanin (KLH) is one of hemocyanins and has many years of experience for vaccine developments and immunological studies in mammals including human. However, the association between KLH and the immune systems, especially the innate immune systems, remains poorly understood. The aim of this study is to clarify the direct effects of KLH on the innate immune systems. KLH activated an inflammation-related transcription factor NF-κB as much as lipopolysaccharide (LPS) in a human monocytic leukemia THP-1 reporter cell line. We have found that the KLH-induced NF-κB activation is partially involved in a spleen tyrosine kinase (Syk) pathway. We have also successfully revealed that an extracellular signal-regulated kinase (Erk), a member of mitogen-activated protein kinases, is located in an upstream of NF-κB activation induced by KLH. Furthermore, a Syk phosphorylation inhibitor partially suppressed the Erk activation in KLH-stimulated THP-1. These results suggest that both Syk and Erk associate with the KLH-induced NF-κB activation in the human monocyte.

description: We investigate dust growth due to settling in a 1D vertical column of a protoplanetary disk. It is known from the observed 10 micron feature in disk SEDs, that small micron-sized grains are present at the disk atmosphere throughout the lifetime of the disk. We hope to explain such questions as what process can keep the disk atmospheres dusty for the lifetime of the disk and how does the particle properties change as a function of height above the midplane. We use a Monte Carlo code to follow the mass and porosity evolution of the particles in time. The used collision model is based on laboratory experiments performed on dust aggregates. As the experiments cannot cover all possible collision scenarios, the largest uncertainty of our model is the necessary extrapolations we had to perform. We simultaneously solve for the particle growth and motion. Particles can move vertically due to settling and turbulent mixing. We assume that the vertical profile of the gas density is fixed in time and only the solid component evolves. We find that the used collision model strongly influences the masses and sizes of the particles. The laboratory experiment based collision model greatly reduces the particle sizes compared to models that assume sticking at all collision velocities. We find that a turbulence parameter of alpha = 10^-2 is needed to keep the dust atmospheres dusty, but such strong turbulence can produce only small particles at the midplane which is not favorable for planetesimal formation models. We also see that the particles are larger at the midplane and smaller at the upper layers of the disk. At 3-4 pressure scale heights micron-sized particles are produced. These particle sizes are needed to explain the 10 micron feature of disk SEDs. Turbulence may therefore help to keep small dust particles in the disk atmosphere.

description: We define a measure of network cohesion and show how it arises naturally in a broad class of dynamic models of endogenous perpetual growth with network externalities. Via a standard growth model, we show why network cohesion is crucial for conditional convergence and explain that as cohesion increases, convergence is faster. We prove properties of network cohesion and define a network aggregator that preserves network cohesion.

Foodshed Vancouver : envisioning a sustainable foodshed for Greater Vancouver
Creators: name: Richardson, James M.
Publisher: name: University of British Columbia
Year: 2010

description: This study explored assessment methods for sustainable foodshed design. A sustainable foodshed was defined as a regional form that meets local food needs, is energetically productive, and is ecologically and socially resilient. Food system energy inputs were measured through a life-cycle assessment of production, distribution, processing, and nutrient cycling inputs to determine the food system energy balance for Greater Vancouver’s hypothetical foodshed. The model accounted for embedded variables such as dietary habits, circulation allotments and distribution chains, ultimately requiring the integration of qualitative and quantitative indicators at a regional, municipal and farm scale. Findings suggest that Canadians purchase roughly 710 kg of food per year, demanding 0.68ha of farmland per capita. If all proximal Agricultural Land Reserve areas were fully utilized to support Greater Vancouver’s 2006 population, it would require 3.5 joules of energy to produce, distribute, prepare and cycle nutrients for every joule of energy contained in the food Vancouverites eat. It may require a radical transformation of dietary habits and processing methods, and a renewed dependency on human-powered agriculture to sustainably feed the population of Greater Vancouver.

description: The stellar astronomy has always been considered the fundamental source of knowledge about the basic building blocks of the universe - the stars. It has proved correctness of many physical theories - like e.g. the idea of nuclear fusion in stellar cores, the exchange of mass in interacting binaries or models of stellar evolution towards white dwarfs or neutron stars. Despite its well acknowledged importance it seems to be loosing its interestingness for students, for telescope allocation committees at large observatories, as well as for granting agencies. In the domain of big telescopes it has been gradually overtaken by the extra-galactic research and cosmology, surviving however at smaller observatories and among most advanced amateur astronomers. We try to analyse the main obstacles lowering the efficiency of research in contemporary stellar astronomy. We will shortly tackle several problems induced by paradigmatic changes in handling the extraordinary amount of data provided by current instruments as well as by introduction of economical criteria and factory-like management into the modern astronomy. Finally we speculate the reasons of a marginal role of Virtual observatory in contemporary stellar research and give some ideas of possible improvements.

description: In this work, the corrosion of stainless-steel K-file and pro taper rotary NiTi-file instruments was evaluated and compared about the effects of 5.25% sodium hypochlorite solution. Thirty new Pro Taper NiTi rotary files (D# 20, 25, and 30) and thirty stainless steel K-files (D# 20, 25, and 30) were subjected to a 5-minute immersion in 5.25% NaOCl at 50°C. Every file was put through the corrosion test, which involved recording the open circuit potential (OCP). Corrosion current, corrosion rate, and corrosion potential were all assigned to each file's recording. A potentiated and a standard calomel electrode reference were used to calculate the percentage of open circuit potential (OCP). The frequency of corrosion that may be seen visually was also studied using a scanning electron microscope (SEM). The findings indicated that the corrosion rate for stainless steel has the following mean and standard deviation: The CR of stainless steel pipes with diameters of # 20, # 25, and # 30 is 5.48 0.81 mpy, 5.23 0.84 mpy, and 5.81 1.04 mpy, respectively. The CR of #20, #25, and #30 diameters of Niti files, on the other hand, are 2.61 0.36 mpy, 4.53 0.65 mpy, and 5.38 0.65 mpy, respectively. Statistics showed that the findings between the two files were significant. Additionally, both files had pitting and crevice corrosion, as seen by scanning electron microscopy (SEM) analysis.NiTi files demonstrated a lower rate of corrosion than stainless steel files

description: Speech acts—promises, apologies, jokes, orders, threats, compliments—are actions we perform with words. This dissertation challenges us to move away from an individualistic theory of speech acts, where the focus is on the speaker and the moment of speech, and towards a more fully social theory of speech acts—a theory of how we perform actions with words over time with others. I call this a Social Contestation Theory of speech acts. Within the philosophy of language, established theories of speech acts present speech acts as actions a speaker performs intentionally in the moment of speaking, requiring either no audience response or only a minimal form of audience uptake (i.e. interpretation of what kind of speech act an utterance is). My dissertation calls this standard picture into question and reconceptualizes what it means to perform a speech act—I argue that performing a speech act is a temporally extended process, which goes beyond the moment of utterance, and within which audience responses play a crucial ongoing role. The Social Contestation Theory of speech acts I develop illuminates the ways that the speech acts we perform are not wholly within our control—speakers can perform some speech acts (such as threats, urgings, and orders) without intending to do so. It also builds on efforts to identify and counter forms of speech-based injustice, highlighting the way power shapes which speech acts we perform and the ethical and political conflicts which can arise within a speaker’s audience.

description: A multilayer edge molecular electronics device (MEMED), which utilize the two metal electrodes of a metal-insulator-metal tunnel junction as the two electrical leads to molecular channels, can overcome the long standing fabrication challenges for developing futuristic molecular devices. However, producing ultrathin insulator is the most challenging step in MEMED fabrication. A simplified molecular device approach was developed by avoiding the need of depositing a new materiel on the bottom electrode for growing ultrathin insulator. This paper discuss the approach for MEMED's insulator growth by one-step oxidation of a tantalum (Ta) bottom electrode, in the pholithographically defined region; i.e. ultrathin tantalum oxide (TaOx) insulator was grown by oxidizing bottom metal electrode itself. Organometallic molecular clusters (OMCs) were bridged across 1-3 nm TaOx along the perimeter of a tunnel junction to establish the highly efficient molecular conduction channels. OMC transformed the asymmetric transport profile of TaOx based tunnel junction into symmetric one. A TaOx based tunnel junction with top ferromagnetic (NiFe) electrode exhibited the transient current suppression by several orders. Further studies will be needed to strengthen the current suppression phenomenon, and to realize the full potential of TaOx based multilayer edge molecular spintronics devices.

description: Echolocating animals that forage in social groups can potentially benefit from eavesdropping on other group members, cooperative foraging or social defence, but may also face problems of acoustic interference and intra-group competition for prey. Here, we investigated these potential trade-offs of sociality for extreme deep-diving Blainville′s and Cuvier's beaked whales. These species perform highly synchronous group dives as a presumed predator-avoidance behaviour, but the benefits and costs of this on foraging have not been investigated. We showed that group members could hear their companions for a median of at least 91% of the vocal foraging phase of their dives. This enabled whales to coordinate their mean travel direction despite differing individual headings as they pursued prey on a minute-by-minute basis. While beaked whales coordinated their echolocation-based foraging periods tightly, individual click and buzz rates were both independent of the number of whales in the group. Thus, their foraging performance was not affected by intra-group competition or interference from group members, and they did not seem to capitalize directly on eavesdropping on the echoes produced by the echolocation clicks of their companions. We concluded that the close diving and vocal synchronization of beaked whale groups that quantitatively reduces predation risk has little impact on foraging performance.

description: In a global business context with continuous changes, the enterprises have to enhance their operational efficiency, to react more quickly, to ensure the flexibility of their business processes, and to build new collaboration pathways with external partners. To achieve this goal, they must use e-business methods, mechanisms and techniques while capitalizing on the potential of new information and communication technologies. In this context, we propose a standards, model and Web services-based approach for modeling and integrating agile enterprise business processes. The purpose is to benefit from Web services characteristics to enhance the processes design and realize their dynamic integration. The choice of focusing on Web services is essentially justified by their broad adoption by enterprises as well as their capability to warranty interoperability between both intra and inter-enterprises systems. Thereby, we propose in this chapter a metamodel for describing business processes, and discuss their dynamic integration by addressing the Web services discovery issue. On the one hand, the proposed metamodel is in line with the W3C Web services standards, namely, WSDL, SAWSDL and WS-Policy. It considers the use of BPMN standard to describe the behavioral aspect of business processes and completes their design using UML diagrams describing their functional, non-functional and semantic aspects. On other hand, our approach for integrating processes is in line with BPEL standard recommended to orchestrate Web services. To realize executable business processes, this approach recommends the use of semantic matching and selection mechanisms in order to produce agile systems.

description: The purpose of the survey, conducted in accordance with Sections 106 and 110 of the National Historic Preservation Act of 1966, as amended, was to evaluate the significance of the BOSU in terms of the criteria of eligibility for listing in the National Register of Historic Places (NRHP) (36 CFR Part 60.4). The facility is proposed for turnover back to the United States Air Force (USAF) to reduce the footprint and inventory of facilities not required for future programs by KSC. If the USAF declines the return of this facility, NASA KSC proposes to demolish the facility in Fiscal Year 2012.

description: Ferromagnetic resonance in thin films is analyzed under the influence of spatiotemporal feedback effects. The equation of motion for the magnetization dynamics is nonlocal in both space and time and includes isotropic, anisotropic and dipolar energy contributions as well as the conserved Gilbert- and the non-conserved Bloch-damping. We derive an analytical expression for the peak-to-peak linewidth. It consists of four separate parts originated by Gilbert damping, Bloch-damping, a mixed Gilbert-Bloch component and a contribution arising from retardation. In an intermediate frequency regime the results are comparable with the commonly used Landau-Lifshitz-Gilbert theory combined with two-magnon processes. Retardation effects together with Gilbert damping lead to a linewidth the frequency dependence of which becomes strongly nonlinear. The relevance and the applicability of our approach to ferromagnetic resonance experiments is discussed.

description: Proteins are large molecules made up of thousands of amino acids, all linked in a chain, and are often referred to as macromolecules. Most proteins are known to only have a single function but during the last decade, a growing number of multifunctional proteins have been discovered. Hundreds of proteins that carry out two or more unique and physiologically significant biochemical or biophysical functions- that is, functions not caused by, numerous RNA splice variants, pleiotropic effects, or gene fusions have been discovered in the last several decades, are called moonlighting proteins. The term "moonlighting proteins" was first used by Jeffery in 1999.

Surface polar states and pyroelectricity in ferroelastics induced by flexo-roto field

description: Theoretical analysis based on the Landau-Ginzburg-Devonshire (LGD) theory is used to show that the joint action of flexoelectric effect and rotostriction leads to a large spontaneous in-plane polarization (~ 1-5 muC/cm2) and pyroelectric coefficient (~10^-3 C/m2K) in the vicinity of surfaces of otherwise non-ferroelectric ferroelastics, such as SrTiO3, with static octahedral rotations. The origin of the improper polarization and pyroelectricity is an electric field we name flexo-roto field whose strength is proportional to the convolution of the flexoelectric and rotostriction tensors with octahedral tilts and their gradients. Flexo-roto field should exist at surfaces and interfaces in all structures with static octahedral rotations, and thus it can induce surface polar states and pyroelectricity in a large class of otherwise nonpolar materials.

description: I review the theoretical aspects of the physics of Higgs bosons, focusing on the elements that are relevant for the production and detection at present hadron colliders. After briefly summarizing the basics of electroweak symmetry breaking in the Standard Model, I discuss Higgs production at the LHC and at the Tevatron, with some focus on the main production mechanism, the gluon-gluon fusion process, and summarize the main Higgs decay modes and the experimental detection channels. I then briefly survey the case of the minimal supersymmetric extension of the Standard Model. In a last section, I review the prospects for determining the fundamental properties of the Higgs particles once they have been experimentally observed.

description: We seek to constrain the formation of the Galactic bulge by means of analysing the detailed chemical composition of a large sample of red clump stars in Baade's window. We measure [Fe/H] in a sample of 219 bulge red clump stars from R=20000 resolution spectra obtained with FLAMES/GIRAFFE at the VLT, using an automatic procedure, differentially to the metal-rich local reference star muLeo. For a subsample of 162 stars, we also derive [Mg/H] from spectral synthesis around the MgI triplet at 6319A. The Fe and Mg metallicity distributions are both asymmetric, with median values of +0.16 and +0.21 respectively. The iron distribution is clearly bimodal, as revealed both by a deconvolution (from observational errors) and a Gaussian decomposition. The decomposition of the observed Fe and Mg metallicity distributions into Gaussian components yields two populations of equal sizes (50% each): a metal-poor component centred around [Fe/H]=-0.30 and [Mg/H]=-0.06 with a large dispersion and a narrow metal-rich component centred around [Fe/H]=+0.32 and [Mg/H]=+0.35. The metal poor component shows high [Mg/Fe] ratios (around 0.3) whereas stars in the metal rich component are found to have near solar ratios. Babusiaux et al. (2010) also find kinematical differences between the two components: the metal poor component shows kinematics compatible with an old spheroid whereas the metal rich component is consistent with a population supporting a bar. In view of their chemical and kinematical properties, we suggest different formation scenarios for the two populations: a rapid formation timescale as an old spheroid for the metal poor component (old bulge) and for the metal rich component, a formation over a longer time scale driven by the evolution of the bar (pseudo-bulge).
