description: We investigate the process of phase conversion in a thermally-driven {\it weakly} first-order quark-hadron transition. This scenario is physically appealing even if the nature of this transition in equilibrium proves to be a smooth crossover for vanishing baryonic chemical potential. We construct an effective potential by combining the equation of state obtained within Lattice QCD for the partonic sector with that of a gas of resonances in the hadronic phase, and present numerical results on bubble profiles, nucleation rates and time evolution, including the effects from reheating on the dynamics for different expansion scenarios. Our findings confirm the standard picture of a cosmological first-order transition, in which the process of phase conversion is entirely dominated by nucleation, also in the case of a weakly first-order transition. On the other hand, we show that, even for expansion rates much lower than those expected in high-energy heavy ion collisions, nucleation is very unlikely, indicating that the main mechanism of phase conversion is spinodal decomposition. Our results are compared to those obtained for a strongly first-order transition, as the one provided by the MIT bag model.

description: We investigate a series of steady-state models of galaxy clusters, in which the hot intracluster gas is efficiently heated by active galactic nucleus (AGN) feedback and thermal conduction, and in which the mass accretion rates are highly reduced compared to those predicted by the standard cooling flow models. We perform a global Lagrangian stability analysis. We show for the first time that the global radial instability in cool core clusters can be suppressed by the AGN feedback mechanism, provided that the feedback efficiency exceeds a critical lower limit. Furthermore, our analysis naturally shows that the clusters can exist in two distinct forms. Globally stable clusters are expected to have either: 1) cool cores stabilized by both AGN feedback and conduction, or 2) non-cool cores stabilized primarily by conduction. Intermediate central temperatures typically lead to globally unstable solutions. This bimodality is consistent with the recently observed anticorrelation between the flatness of the temperature profiles and the AGN activity (Dunn & Fabian 2008) and the observation by Rafferty et al. (2008) that the shorter central cooling times tend to correspond to significantly younger AGN X-ray cavities.

Studies on protamine
Creators: name: Ingles, Charles James
Publisher: name: University of British Columbia

description: Spermatogenesis in fish is a remarkable example of a rapid and extreme form of cellular differentiation. Protamines, the small basic proteins associated with DNA in the spermatozoa of certain fish, are perhaps the most characteristic of the sperm-specific macromolecules. A study of the synthesis of these unusual proteins was initiated using suspensions of cells from the testes of both naturally maturing Pacific salmon (Oncorhynchus spp.) and immature Salmo gaird-nerii in which spermatogenesis had been induced by the injection of salmon pituitary extracts. Protamine, easily characterized by polyacrylamide gel electrophoresis, was only present in the acid extract of testis tissue at a late stage of spermatogenesis. The incorporation of arginine-H³ into protamine was studied in this testis cell suspension system. The inhibition of protamine synthesis by puromycin, cycloheximide and chloramphenicol indicated that in spite of their small size and unusual amino acid composition, protamines were synthesized by a mRNA, tRNA, ribosomal system Actinomycin D, however, did not inhibit this synthesis of protamine. Protamines from several different species of salmonoid fish were purified by a two step chromatography procedure utilizing gel filtration on Sephadex G-25 and Biogel P-10. The amino acid compositions of these protamines were compared, the N and C-terminal amino acids of the Salmo gairdnerii protamine determined, and fractionation of the components of Oncorhynchus tshawytscha (chinook salmon) protamine, by chromatography on both carboxymethyl Sephadex and alumina, attempted. During the late stages of maturation, the testis cells from S. gairdnerii, which are synthesizing protamine, have been shown to incorporate phosphate-P³² into both histone and protamine fractions. The site of this phosphorylation of protamine was identified as seryl residues, and a number of radioactive phospho-peptides were isolated from the tryptic digest of protamine-P³². The major phospho-peptide was identified as val-serP-arg; however phosphorylation of other serine sequences in protamine was indicated by the presence of the peptides (ala,serP,arg)arg, (ser,serP)arg and arg-serP-serP-arg. This phosphorylation of protamine proceeded independently of the amino acid incorporation during synthesis of protamine; however, parallel incorporation of phosphate-P³² and serine-C¹⁴ into protamine showed that all newly incorporated seryl residues were phosphorylated. Since the total content of o-phosphoserine in protamine fell during the later stages of testis maturation, a rapid turnover of phosphate in protamine was indicated. This view was confirmed by the almost complete absence of phosphate in protamine prepared from mature spermatozoa of naturally spawning salmonoid fish. The phosphorylation of protamine may play a role both in the synthesis and intracellular transport of protamine, and in the control of gene expression in these testis cells.

description: We investigate the question whether there is a real difference in the light change between stars classified as semiregular (SRV) or irregular (Lb) variables by analysing photometric light curves of 12 representatives of each class. Using Fourier analysis we try to find a periodic signal in each light curve and determine the S/N of this signal. For all stars, independent of their variability class we detect a period above the significance threshold. No difference in the measured S/N between the two classes could be found. We propose that the Lb stars can be seen as an extension of the SRVs towards shorter periods and smaller amplitudes. This is in agreement with findings from other quantities which also showed no marked difference between the two classes.

MetaDTA: An interactive web-based tool for meta-analysis of diagnostic test accuracy studies. Presentation at ESMARConf2021
Creators: name: Freeman, Suzanne
Publisher: name: figshare
Year: 2021
Subjects: Uncategorized

description: Diagnostic tests are routinely used in healthcare settings to split patients into one of two groups: diseased and non-diseased individuals. The accuracy of diagnostic tests is measured in terms of two outcomes: sensitivity and specificity. The recommended approach for synthesising diagnostic test accuracy (DTA) studies is to use either the bivariate or hierarchical summary receiver operating characteristic (HSROC) models, which account for the correlation between sensitivity and specificity with the results presented either around a mean accuracy point or as a summary receiver operating characteristic (SROC) curve. Software options for fitting bivariate and HSROC models are available in R but require statistical knowledge. We developed MetaDTA, a freely available web-based “point and click” interactive tool, which allows users to input their DTA study data and conduct meta-analyses of DTA studies, including sensitivity analyses. MetaDTA is a Shiny application, which uses the lme4 package for conducting statistical analyses and 22 other R packages to provide an intuitive easy-to-use interface. MetaDTA incorporates novel approaches to visualising SROC curves allowing users to visualise study quality and/or percentage study contributions on the same plot as the individual study estimates and the meta-analysis results. Multiple features can be combined within a single plot. All tables and plots can be downloaded. MetaDTA is available at: https://crsu.shinyapps.io/dta_ma/.

description: We propose a simple phenomenological model for wet granular media to take into account many particle interaction through liquid in the funicular state as well as two-body cohesive force by a liquid bridge in the pendular state. In the wet granular media with small liquid content, liquid forms a bridge at each contact point, which induces two-body cohesive force due to the surface tension. As the liquid content increases, some liquid bridges merge, and more than two grains interact through a single liquid cluster. In our model, the cohesive force acts between the grains connected by a liquid-gas interface. As the liquid content increases, the number of grains that interact through the liquid increases, but the liquid-gas interface may decrease when liquid clusters are formed. Due to this competition, our model shows that the shear stress has a maximum as a function of the liquid-content.

title: World food security and international organisations: the case of international grain reserves
Creators: name: Sage, Irene Elizabeth
Publisher: name: University of Kent
Year: 2021

description: The seemingly insurmountable commercial and political difficulties in establishing order in the international grain trade have plagued policy-makers throughout history. The suspension of international agreement on the rules of orderly marketing in the late 1960's and early 1970's, has resulted in extreme price and supply volatility. Many national and international initiatives have been instituted in an attempt to minimise the damaging effects of extreme price and supply fluctuations. The purpose of this thesis is to assess the nature of grain as an internationally traded commodity, and the effectiveness of national and international options which have been adopted in order to achieve these dual objectives. The study shows that the biological nature of the commodity has precluded reliable production estimates and has demanded exceptionally in the treatment of grain in the context of more general economic planning. The major grain exporters, the United States, Canada, Australia, Argentina and the European Union have attempted to protect their domestic producer, consumer and corporate interests as well as their international markets through a host of national and international policies. I will specifically examine in detail a particular proposal for the establishment of international grain reserves tabled by the United States through the FAO at the World Food Conference of 1974. The politics and technical questions relating to that proposal will be discussed and new information will be revealed as to the nature of the negotiations and the cause of the breakdown of the negotiations when agreement seemed near. A synthesis of new material regarding the grain reserve negotiations and private interviews conducted by principals to the negotiations will reveal that the negotiations were not abandoned as a result of technical barriers, but rather to serve the political and market imperatives of some exporters.

We also discuss more distant opportunities for exploring the nature of laws of physics and the vacuum structure. We then conclude that the predictions of quantum electrodynamics in the presence of critical fields are not completely satisfactory and argue that the study of Laser materialization into particle pairs opens a new domain of quantum electrodynamics.

description: Two fundamental facts of the modern wave turbulence theory are 1) existence of power energy spectra in $k$-space, and 2) existence of "gaps" in this spectra corresponding to the resonance clustering. Accordingly, three wave turbulent regimes are singled out: \emph{kinetic}, described by wave kinetic equations and power energy spectra; \emph{discrete}, characterized by resonance clustering; and \emph{mesoscopic}, where both types of wave field time evolution coexist. In this paper we study integrable dynamics of resonance clusters appearing in discrete and mesoscopic wave turbulent regimes. Using a novel method based on the notion of dynamical invariant we establish that some of the frequently met clusters are integrable in quadratures for arbitrary initial conditions and some others -- only for particular initial conditions. We also identify chaotic behaviour in some cases. Physical implications of the results obtained are discussed.

description: Analytical expressions for the saturation density as well as the binding energy and incompressibility at the saturation density of asymmetric nuclear matter are given exactly up to 4th-order in the isospin asymmetry delta =(rho_n - rho_p)/rho using 11 characteristic parameters defined at the normal nuclear density rho_0. Using an isospin- and momentum-dependent modified Gogny (MDI) interaction and the SHF approach with 63 popular Skyrme interactions, we have systematically studied the isospin dependence of the saturation properties of asymmetric nuclear matter, particularly the incompressibility $K_{sat}(δ)=K_{0}+K_{sat,2}δ^{2}+K_{sat,4}δ^{4}+O(δ^{6})$ at the saturation density. Our results show that the magnitude of the high-order $K_{sat,4}$ parameter is generally small compared to that of the $K_{\sat,2}$ parameter. The latter essentially characterizes the isospin dependence of the incompressibility at the saturation density and can be expressed as $K_{sat,2}=K_{sym}-6L-\frac{J_{0}}{K_{0}}L$, Furthermore, we have constructed a phenomenological modified Skyrme-like (MSL) model which can reasonably describe the general properties of symmetric nuclear matter and the symmetry energy predicted by both the MDI model and the SHF approach. The results indicate that the high-order $J_{0}$ contribution to $K_{sat,2}$ generally cannot be neglected. In addition, it is found that there exists a nicely linear correlation between $K_{sym}$ and $L$ as well as between $J_{0}/K_{0}$ and $K_{0}$. These correlations together with the empirical constraints on $K_{0}$, $L$, $E_{sym}(ρ_{0})$ and the nucleon effective mass lead to an estimate of $K_{sat,2}=-370\pm 120$ MeV.

An analysis of aids to small business in Canada
Creators: name: Bucknall, James
Publisher: name: University of British Columbia
Year: 2011

description: Periodically concern is shown over the plight of small business in most of the industrial countries of the West. This concern has recently been voiced in Canada and monies were made available to investigate the position of small business in this country. The prime purpose of this study was to investigate the various government and private aids which it was felt could be of assistance to small business and to evaluate their effectiveness in assisting the small businessman in running his business. A secondary yet complementary aim was to determine what problems still faced small business. First a compendium of federal, provincial, municipal and private aids to business was compiled. This was produced by thorough review of annual reports of federal and provincial departments concerned and also by the thorough review of numerous government and private publications, brochures and pamphlets. To determine the effectiveness and usefullness of aids to small business in Canada a questionnaire was compiled and mailed to businesses in the three provinces of Nova Scotia, Ontario and Manitoba. Several very general conclusions may be made with respect to aids to small business in Canada. First, with one or two notable exceptions all forms of aids are directed to primary and secondary industry often with the specific exclusion of tertiary industry. Another discernible trend is that of the increased role the provincial governments are playing in assisting business. This is so even though both the federal and provincial governments have increased the scope of aid offered. The final conclusion with respect to aids to small business in Canada is that in general they are quite adequate. No major changes to the present system of aids to small business would appear desirable but there is evidence that improvements in financial aids, management education and management services, and the promotion of existing services would appear desirable.

Results from quantum process tomography and randomized benchmarking are compared with gate errors obtained from a double pi pulse experiment. Randomized benchmarking reveals a minimum average gate error of 1.1+/-0.3% and a simple exponential dependence of fidelity on the number of gates. It shows that the limits on gate fidelity are primarily imposed by qubit decoherence, in agreement with theory.

description: Meta-analysis is a key quantitative component of evidence synthesis. Over the last 40 years the popularity and utility of meta analytic methods has had an enormous impact in biology, ecology, medicine, and the social sciences. Within the fields of medicine and public health it has become an essential method for medical professionals and scholars on summarizing the known effects of medical treatments and interventions. For example, these analyses can combine the results from multiple published studies to evaluate the effectiveness of a drug or investigate the effectiveness of behavior on health. MAJOR is an add on module for the open source Jamovi statistical platform which allows users to produce a publication quality meta-analysis. Both software projects are quickly being adopted for use in classes and workshops by colleges, universities, and medical schools around the world as a replacement for expensive proprietary statistical software. Jamovi uses an intuitive point and click interface which lowers the learning curve required to run analyses. Also, both Jamovi and MAJOR use R to run the analyses and can create reproducible analyses scripts for use in the native R environment. MAJOR combines a variety of packages from the R community, including the popular metafor package to produce fixed, random, and mixed effects meta-analytic models, methods for detecting publication bias, effect size calculators, and generation of publication grade graphics.

description: Large sampling intervals can affect reconstruction of Kramers-Moyal coefficients from data. A new method, which is direct, non-stochastic and exact up to numerical accuracy, can estimate these finite-time effects. For the first time, exact finite-time effects are described analytically for special cases; biologically inspired numerical examples are also worked through numerically. The approach developed here will permit better evaluation of Langevin or Fokker-Planck based models from data with large sampling intervals. It can also be used to predict the sampling intervals for which finite-time effects become significant.

description: An analysis of proper motion measurements of the Young Stellar Objects (YSOs) associated with the Cometary Globules (CGs) in the Gum Nebula is presented. While earlier studies based on the radial velocity measurements of the CGs suggested expansion of the system of the CGs, the observed proper motion of the YSOs shows no evidence for expansion. In particular the kinematics of two YSOs embedded in CGs is inconsistent with the supernova explosion of the companion of $ζ$ Pup about 1.5 Myr ago as the cause of the expansion of the CG system. YSOs associated with the CGs share the average proper motion of the member stars of the Vela OB2 association. A few YSOs that have relatively large proper motions are found to show relatively low infrared excesses.

description: We report the discovery of the transiting giant planet WASP-17b, the least-dense planet currently known. It is 1.6 Saturn masses but 1.5-2 Jupiter radii, giving a density of 6-14 per cent that of Jupiter. WASP-17b is in a 3.7-day orbit around a sub-solar metallicity, V = 11.6, F6 star. Preliminary detection of the Rossiter-McLaughlin effect suggests that WASP-17b is in a retrograde orbit (lambda ~ -150 deg), indicative of a violent history involving planet-planet or star-planet scattering. WASP-17b's bloated radius could be due to tidal heating resulting from recent or ongoing tidal circularisation of an eccentric orbit, such as the highly eccentric orbits that typically result from scattering interactions. It will thus be important to determine more precisely the current orbital eccentricity by further high-precision radial velocity measurements or by timing the secondary eclipse, both to reduce the uncertainty on the planet's radius and to test tidal-heating models. Owing to its low surface gravity, WASP-17b's atmosphere has the largest scale height of any known planet, making it a good target for transmission spectroscopy.

description: We computed a Lennard Jones frozen liquid with a free surface using classical molecular dynamics. The structure factor curves on the free surface of this sample was calculated for different depths knowing that we have periodic boundary conditions on the other parts of the sample. The resulting structure factor curves show an horizontal shift of their first peak depending on how deep in the sample the curves are computed. We analyze our resulting curves in the light of spatial correlation functions during melting and at when the liquid is frozen. The conclusion is that near the free surface the sample is less dense than in the bulk and that the frozen liquid surface has a spatial correlation which does not differ very much from that of the bulk. This result is intrinsic to the melting of the Lennard Jones liquid and does not depend on any other parameter.

description: Central to the Australian Government's approach to the Southwest Pacific is the view that Australia has a special role to play in the region. Enhancing Australia's leadership role in contributing to security and stability in the region is at the core of this approach. The perceived withdrawal from the region by the United States has heightened the importance of Australia's role and to a lesser extent New Zealand's, which has been Australia's main partner in regional peacekeeping operations.
Superplasticity and creep behaviour in pure zirconia
Creators: name: Hart, John Laurie
Publisher: name: University of British Columbia
Year: 2011

description: An investigation of creep deformation in pure zirconia, using a creep-in-bending method with programmed temperature increase, showed the occurrence of superplasticity at temperatures near the monoclinic to tetragonal phase transformation. An interesting phenomenon was observed in a temporary halt to the creep process which occurred with continuing temperature increase beyond the phase transformation. Temperature dependence tests at a maximum fibre stress of 3140 psi gave overall activation energies for the creep process in pure zirconia in the monoclinic and tetragonal phases of 44 and 103 kcal/mole respectively.

description: The ensemble variability properties of nearly 23,000 quasars are studied using the Palomar-QUEST Survey. The survey has covered 15,000 square degrees multiple times over 3.5 years using 7 optical filters, and has been calibrated specifically for variability work. Palomar-QUEST allows for the study of rare objects using multiple epochs of consistently calibrated, homogeneous data, obviating the common problem of generating comparable measurements from disparate datasets. A power law fit to the quasar structure function versus time yields an index of 0.432 +/- 0.024 for our best measured sample. We see the commonly reported anticorrelation between average optical variability amplitude and optical luminosity, and measure the logarithmic decrease in variability amplitude to scale as the logarithm of the luminosity times 0.205 +/- 0.002. Black hole mass is positively correlated with variability amplitude over three orders of magnitude in mass. Quasar variability amplitude is seen to decrease with Eddington ratio as a step function with a transition around Eddington ratio of 0.5. The higher variability at low Eddington ratios is due to excess power at timescales shorter than roughly 300 days. X-ray and radio measurements exist for subsets of the quasar sample. We observe an anticorrelation between optical variability amplitude and X-ray luminosity. No significant correlation is seen between average optical variability properties and radio luminosity. The timescales of quasar fluctuations are suggestive of accretion disk instabilities. The relationships seen between variability, Eddington ratio, and radio and X-ray emission are discussed in terms of a possible link between the behavior of quasars and black hole X-ray binaries.

Detecting Lyman Alpha Emitters in the Sub-millimeter

description: Using the results from a previously developed Lyman Alpha/continuum production/transmission and dust enrichment model for Lyman Alpha Emitters (LAEs), based on cosmological SPH simulations, we assess the detectability of their dust-reprocessed sub-millimeter (submm) radiation. As supernovae (rather than evolved stars) control dust formation and destruction processes, LAEs are relatively dust-poor with respect to local galaxies: they have low dust-to-gas ratios (0.05 times the dust-to-gas ratio of the Milky Way) in spite of their relatively high metallicity, which is approximately 10-50% of the solar value. Using the derived escape fraction of ultraviolet (UV) continuum photons we compute the UV luminosity absorbed by dust and re-emitted in the far infrared. The LAE submm fluxes correlate with their Lyman Alpha luminosity: about (3%, 1%) at z=(5.7, 6.6) of the LAEs in our simulated sample (those with with Log L_α> 43.1) would have fluxes at 850 micrometer (the optimal band for detection) in excess of 0.12 mJy and will be therefore detectable at 5 sigma with ALMA with an integration time of only 1 hour. Such detections would open a new window on the physical conditions prevailing in these most distant galaxies.

Sol-gel obtained YSZ nanocrystals on a substrate: a Monte Carlo approach of the crystallographic orientation

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Sol gel obtained YZS (Yttria Stabilized Zirconia) nanocrystals have different morphologies when they grow on an $α$-alumina substrate after thermal treatment. When the substrate has planar defects, the nanocrystals grow in height and are narrow with a crystallographic orientation [111] in the vertical direction, while when the substrate is a perfect plane at the nanometric scale, the nanocrystals are rather extended over the substrate and do not grow in height, with a crystallo- graphic orientation [100] in the vertical direction. We present here a Monte Carlo approach which computes the actions of the substrate on the nanocrystals during thermal treatment: one action is the change in crystallographic orientation depending on the presence of defects and the other is the action on the morphology of the nanocrystals. The equivalent of thermal treatment is obtained after applying the Metropolis algorithm with adequate expressions of the energy depending on the inter-plane spacings and surface diffusion. Our numerical approach is in good agreement with the experimental results on the orientations and morphologies of the YSZ nanocrystals growing on a $α$-alumina substrate with planar defects

Strong Coupling Quantum Einstein Gravity at a z=2 Lifshitz Point

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We solve a renormalized Wheeler-DeWitt equation for Einstein gravity in D+1 dimensions with D= odd in the strong coupling limit, which is expected to be suited to probe quantum geometry at short distances, in order to test Horava's idea that quantum gravity at short distances will be described by a nonrelativistic system with dynamical critical exponent z>1. Our results support the idea and show that the Wheeler-DeWitt equation possesses a solution associated with a z=2 Lifshitz point but no other z>2 solutions to leading order of the strong coupling expansion.

description: We present a theoretical framework to accurately calculate the location of the multicritical point in the phase diagram of spin glasses. The result shows excellent agreement with numerical estimates. The basic idea is a combination of the duality relation, the replica method, and the gauge symmetry. An additional element of the renormalization group, in particular in the context of hierarchical lattices, leads to impressive improvements of the predictions.
