description: We examine the exact relation between the superconformal symmetry breaking chiral superfield (X) and the goldstino superfield in microscopic models of an arbitrary Kahler potential (K) and in the presence of matter fields. We investigate the decoupling of the massive sgoldstino and scalar matter fields and the offshell/onshell-SUSY expressions of their superfields in terms of the fermions composites. For general K of two superfields, we study the properties of the superfield X after integrating out these scalar fields, to show that in the infrared it satisfies (offshell) the condition $X^3=0$ and $X^2\not=0$. We then compare our results to those of the well-known method of constrained superfields discussed in the literature, based on the conjecture $X^2=0$. Our results can be used in applications, to couple offshell the (s)goldstino fields to realistic models such as the MSSM.

description: By the end of the 19th century, the madrasahs of the East, which had been the cradle of science for centuries, rapidly fell into a crisis towards scholastic views. By this century, while the industrialized science and technology revolution was taking place in Europe, the Muslims of Russia, including Turkestan, were in the middle of the old and new debates. The Jadidism movement spread widely in all regions of the Russian Empire and was distinguished by its comprehensiveness. The educational reforms of this movement gained special importance in the regions of Turkestan and Tatarstan, and the role of this movement in the education system was studied in detail through these regions.

Introduction. The education system for Muslims in the Idyll-Ural region was mainly implemented by mudarris who studied in Bukhara. Naturally, by the end of the 19th century and the beginning of the 20th century, the old school and madrasah system, which could not meet the needs of the times, had to be reformed. For this reason, a group of progressives published articles on their educational reforms in the national press.

description: Experimental absolute-rate coefficients for electron-impact excitation of C3+ (2s2S1/2→2p2P1/2,3/2) near threshold [D. W. Savin, L. D. Gardner, D. B. Reisenfeld, A. R. Young, and J. L. Kohl, Phys. Rev. A 51, 2162 (1995)] have been reanalyzed to include a more accurate determination of optical efficiency and revised radiometric uncertainties which reduce the total systematic uncertainty of the results. Also, new R matrix with pseudostates (RMPS) calculations for this transition near threshold are presented. Comparison of the RMPS results to those of simpler close-coupling calculations indicates the importance of accounting for target continuum effects. The reanalyzed results of Savin et al. are in excellent agreement with the RMPS calculations; comparisons are also made to other measurements of this excitation. Agreement with the RMPS results is better for fluorescence technique measurements than for electron-energy-loss measurements.

description: Highlights of Lambda-Lambda emulsion events are briefly reviewed. Given three accepted events, shell-model predictions based on p-shell Lambda hypernuclear spectroscopic studies are shown to reproduce the Lambda-Lambda (LL) binding energies of LL10Be and LL13B in terms of the LL binding energy of LL6He. Predictions for other species offer judgement on several alternative assignments of the LL13B KEK-E176 event, and on the assignments LL11Be and LL12Be suggested recently for the KEK-E373 HIDA event. The predictions of the shell model, spanning a wide range of A values, are compared with those of cluster models, where the latter are available.

description: In photoionized gases with cosmic abundances, dielectronic recombination (DR) proceeds primarily via nlj → nl'j' core excitations (Δn = 0 DR). We have measured the resonance strengths and energies for Fe XVIII to Fe XVII and Fe XIX to Fe XVIII Δn = 0 DR. Using our measurements, we have calculated the Fe XVIII and Fe XIX Δn = 0 DR rate coefficients. Significant discrepancies exist between our inferred rates and those of published calculations. These calculations overestimate the DR rates by factors of ~2 or underestimate it by factors of ~2 to orders of magnitude, but none are in good agreement with our results. Almost all published DR rates for modeling cosmic plasmas are computed using the same theoretical techniques as the above-mentioned calculations. Hence, our measurements call into question all theoretical Δn = 0 DR rates used for ionization balance calculations of cosmic plasmas. At temperatures where the Fe XVIII and Fe XIX fractional abundances are predicted to peak in photoionized gases of cosmic abundances, the theoretical rates underestimate the Fe XVIII DR rate by a factor of ~2 and overestimate the Fe XIX DR rate by a factor of ~1.6. We have carried out new multiconfiguration Dirac-Fock and multiconfiguration Breit-Pauli calculations which agree with our measured resonance strengths and rate coefficients to within typically better than ≲30%. We provide a fit to our inferred rate coefficients for use in plasma modeling. Using our DR measurements, we infer a factor of ~2 error in the Fe XX through Fe XXIV Δn = 0 DR rates. We investigate the effects of this estimated error for the well-known thermal instability of photoionized gas. We find that errors in these rates cannot remove the instability, but they do dramatically affect the range in parameter space over which it forms.

description: Transport properties of two coupled Josephson junctions driven by ac currents and thermal fluctuations are studied with the purpose of determining dc voltage characteristics. It is a physical realization of directed transport induced by a non-biased zero averaged external signal. The ac current is applied either to (A) only one junction as a biharmonic current or (B) is split into two simple harmonic components and separately applied to respective junctions. We identify regimes where junctions can operate with the same as well as opposite signs of voltages. A general observation is that in the same parameters regimes, the scenario (B) is more efficient in the sense that the induced dc voltages take greater values.

description: Memory awareness in early Alzheimer’s disease (AD) influences capacity to provide informed consent for a memory treatment. This study investigated the extent to which aspects of memory awareness influence everyday decision-making capacity about medication management in AD. 42 participants with mild AD and 50 healthy elders underwent clinical ratings of memory awareness, metamemory testing, and an interview of everyday decision-making capacity regarding medication management. 45% of  AD subjects  were classified as aware  (AAD) and 55% as unaware (UAD) based on clinical ratings and supported by metamemory testing (P = .01). Capacity was impaired in each of the AD groups as compared to the healthy elders F(2, 67) = 17.63, UAD, P less than .01; AAD, p = .01). Within the AD group, capacity correlated selectively with awareness as measured with clinical ratings (r = -.41, P = .007) but not objective metamemory testing (r = -.10, P = .60). Appreciation scores were lower in UAD as compared with AAD F(1, 35) = 8.36, P = .007. Unawareness of memory loss should heighten clinicians’ concern about everyday decision-making capacity in AD.

description: Overlap is one of the characteristics of social networks, in which a person may belong to more than one social group. For this reason, discovering overlapping structures is necessary for realistic social analysis. In this paper, we present a novel, general framework to detect and analyze both individual overlapping nodes and entire communities. In this framework, nodes exchange labels according to dynamic interaction rules. A specific implementation called Speaker-listener Label Propagation Algorithm (SLPA1) demonstrates an excellent performance in identifying both overlapping nodes and overlapping communities with different degrees of diversity.

Transformational teaching and relational efficacy beliefs among adolescents : a prospective observational study
Creators: name: Bourne, Jessica
Publisher: name: University of British Columbia
Year: 2011

description: It has recently been reported that Canadian youth are not meeting daily physical activity guidelines and as a result are potentially at increased risk of current and future physical and mental health problems. School-based physical education has been highlighted as a particularly salient setting in which life-long physical activity behaviour can be positively promoted. The overall purpose of this thesis was to apply the tenets of transformational leadership theory with a view to understanding the prospective relationships between students perceptions of transformational teaching and students’ (a) personal efficacy beliefs (task self-efficacy, self-regulatory efficacy), (b) relational efficacy beliefs (other-efficacy, relation-inferred self-efficacy), as well as (c) physical activity behaviours (within-class time and also during leisure time). Seven hundred and fifty three grade 10 adolescents participated in this research. Students completed a 20-minute questionnaire at two time points, eight weeks apart. In addition, a sub-sample of 53 students wore accelerometers for 5 consecutive days at each of the two time points. Analyses were conducted separately for males and females based on mean differences at baseline. However, the pattern of results between the independent and criterion measures in this study were largely the same for males and females. Results indicated that student perceptions of transformational teaching were able to explain significant variance in student self-efficacy, RISE and other-efficacy beliefs in the context of performing physical education tasks. Furthermore, a positive relationship between transformational teaching and within-class physical activity behaviour was found. No association was found between transformational teaching perceptions and leisure time physical activity behaviour. Self-regulatory efficacy (the belief a person has in his/her ability to self-regulate behaviour in the face of challenges and set-backs) and physical education self-efficacy (the belief one has in his/her ability to perform tasks in the context of physical education classes) were found to be positively associated with leisure time physical activity. Collectively, this research demonstrates the utility of transformational teaching in predicting adolescents’ health-enhancing cognitions and physical activity behaviour, specifically within physical education class settings.

description: We calculate the reduced density matrix of a block of integer spin-S's in a q-deformed valence-bond-solid (VBS) state. This matrix is diagonalized exactly for an infinitely long block in an infinitely long chain. We construct an effective Hamiltonian with the same spectrum as the logarithm of the density matrix. We also derive analytic expressions for the von Neumann and Rényi entanglement entropies. For blocks of finite length, we calculate the eigenvalues of the reduced density matrix by perturbation theory and numerical diagonalization. These results enable us to describe the effects of finite-size corrections on the entanglement spectrum and entropy in this generalized VBS model.

Influence of the tetraneutron on the EoS under core-collapse supernovae and heavy-ion collisions conditions

description: Recently, a resonant state of four neutrons (tetraneutron) with an energy of $E_{4n}=2.37\pm 0.38 \rm{(stat)} \pm 0.44 \rm{(sys)}$ MeV and a width of $Γ=1.75\pm 0.22 \rm{(stat)} \pm 0.30 \rm{(sys)}$ MeV was reported. In this work, we analyse the effect of including such an exotic state on the yields of other light clusters, that not only form in astrophysical sites, such as core-collapse supernovae and neutron star mergers, but also in heavy-ion collisions. To this aim, we use a relativistic mean-field formalism, where we consider in-medium effects in a two-fold way, via the couplings of the clusters to the mesons, and via a binding energy shift, to compute the low-density equation of state for nuclear matter at finite temperature and fixed proton fraction. We consider five light clusters, deuterons, tritons, heliums, $α$-particles, and $^6$He, immersed in a gas of protons and neutrons, and we calculate their abundances and chemical equilibrium constants with and without the tetraneutron. We also analyse how the associated energy of the tetraneutron would influence such results. We find that the low-temperature, neutron-rich systems, are the ones most affected by the presence of the tetraneutron, making neutron stars excellent environments for their formation. Moreover, its presence in strongly asymmetric matter may increase considerably the proton and the $α$-particle fractions. This may have an influence on the dissolution of the accretion disk of the merger of two neutron stars.

description: This paper presents a detailed and precise study of the characteristics of the Exoplanet Host Star and CoRoT main target HD 52265, as derived from asteroseismic studies. The results are compared with previous estimates, with a comprehensive summary and discussion. The basic method is similar to that previously used by the Toulouse group for solar-type stars. Models are computed with various initial chemical compositions and the computed p-mode frequencies are compared with the observed ones. All models include atomic diffusion and the importance of radiative accelerations is discussed. Several tests are used, including the usual frequency combinations and the fits of the échelle diagrams. The possible surface effects are introduced and discussed. Automatic codes are also used to find the best model for this star (SEEK, AMP) and their results are compared with that obtained with the detailed method. We find precise results for the mass, radius and age of this star, as well as its effective temperature and luminosity. We also give an estimate of the initial helium abundance. These results are important for the characterization of the star-planet system.

description: The recognition mechanism and cleavage activity of argonaute (Ago), miRNA, and mRNA complexes are the core processes to the small non-coding RNA world. The 5′ nucleation at the ‘seed’ region (position 2–8) of miRNA was believed to play a significant role in guiding the recognition of target mRNAs to the given miRNA family. In this paper, we have performed all-atom molecular dynamics simulations of the related and recently revealed Ago-DNA:mRNA ternary complexes to study the dynamics of the guide-target recognition and the effect of mutations by introducing “damaging” C·C mismatches at different positions in the seed region of the DNA-RNA duplex. Our simulations show that the A-form-like helix duplex gradually distorts as the number of seed mismatches increases and the complex can survive no more than two such mismatches. Severe distortions of the guide-target heteroduplex are observed in the ruinous 4-sites mismatch mutant, which give rise to a bending motion of the PAZ domain along the L1/L2 “hinge-like” connection segment, resulting in the opening of the nucleic-acid-binding channel. These long-range interactions between the seed region and PAZ domain, moderated by the L1/L2 segments, reveal the central role of the seed region in the guide-target strands recognition: it not only determines the guide-target heteroduplex’s nucleation and propagation, but also regulates the dynamic motions of Ago domains around the nucleic-acid-binding channel.

description: We describe a necessary and sufficient condition for a principal circle bundle over an even-dimensional manifold to carry an invariant contact structure. As a corollary it is shown that all circle bundles over a given base manifold carry an invariant contact structure, only provided the trivial bundle does. In particular, all circle bundles over 4-manifolds admit invariant contact structures. We also discuss the Bourgeois construction of contact structures on odd-dimensional tori in this context, and we relate our results to recent work of Massot, Niederkrueger and Wendl on weak symplectic fillings in higher dimensions.

Imperialism and widowhood: British widows of the 1857 Indian 'mutiny'
Creators: name: Hinshaw, Judith
Publisher: name: University of Calgary
Year: 2011

description: Bibliography: p. 272-289.
description: Just as women who accompanied their husbands into the spaces of the British Empire have been termed imperial wives, those whose husbands died there can be considered imperial widows. To date, discussions of British nineteenth-century attitudes toward death and mourning practices have had a primarily domestic focus. This study examines how the British women widowed by the 1857 Indian Mutiny negotiated the Victorian prescriptions for death and mourning, not only in imperial spaces but under the duress of conflict and deprivation. In doing so, it looks at the inherent tension in domestic/imperial marriages as well as nuances in the determination of women's complicity in or resistance to imperial missions. Furthermore as remnants and representatives of the imperial conflict, these women symbolized both domestic and national loss to Britain. This study follows the women to Britain where they were received as both victims and heroines. It examines the response of the traumatized nation to the women whose vulnerability echoed its own. The anxiety of the population became largely focused on the perceived duty of the nation to provide financial succour for all the widows whose protectors and providers had been sacrificed to the imperial cause. While the substantial Indian Mutiny Relief Fund, which resulted from generous public donations, ensured that all deserving widows received support, its regulations that the widows of soldiers in particular be industrious and respectable reinforced the imperatives of class. In addition to the Relief Fund, an examination of the range of other sources of income provides insight into how the widows negotiated their individual circumstances. Shortly after experiencing the fanfare which greeted the returning widows, the women disappeared from public view. This study looks at where the heroines went by examining the lives and subjectivity of several of the widows. It engages with their choices to remarry or remain widows, where and with whom to live, and their continuing ties to India and/or the imperial missions. In doing so, it not only demonstrates the diversity of widows' experiences but through them how the mutiny and the empire became woven into the narrative of British families and communities.

description: Indian agricultural policy discussion has taken place against the background of a trend rise in agricultural production, especially of foodgrains, which has fallen sufficiently short of the growth in demand arising from income and population growth to require continual and significant import of foodgrains under the P.L. 480 program. In consequence, economic analysis has largely been concerned with questions relating to agricultural price and distribution policy, and also the economic efficiency of alternative forms of land tenure and agrarian organization.

description: The Bell-Kochen-Specker theorem (BKS) theorem rules out realistic {\it non-contextual} theories by resorting to impossible assignments of rays among a selected set of maximal orthogonal bases. We investigate the geometrical structure of small $v-l$ BKS-proofs involving $v$ real rays and $l$ $2n$-dimensional bases of $n$-qubits ($1< n < 5$). Specifically, we look at the parity proof 18-9 with two qubits (A. Cabello, 1996), the parity proof 36-11 with three qubits (M. Kernaghan & A. Peres, 1995 \cite{Kernaghan1965}) and a newly discovered non-parity proof 80-21 with four qubits (that improves work of P. K Aravind's group in 2008). The rays in question arise as real eigenstates shared by some maximal commuting sets (bases) of operators in the $n$-qubit Pauli group. One finds characteristic signatures of the distances between the bases, which carry various symmetries in their graphs.

description: We study quantum stability bound on the mass of scalaron in generic theories of $f(R)$ gravity. We show that in these scenarios, the scalaron mass increases faster with local density of the environment than one loop quantum correction to it thereby leading to violation of quantum bound on the chameleon mass. The introduction of quadratic curvature corrections in the action are shown to stabilize the model.

Projective Quantum Phase Difference Estimation Algorithm for the Direct Computation of Eigenenergy Gaps on a Quantum Computer
Creators: name: Sugisaki, Kenji
Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum computers are capable of calculating the energy gap of two electronic states by using the quantum phase difference estimation (QPDE) algorithm. The Bayesian inference based implementations for the QPDE have been reported so far, but this approach is not projective, and the quality of the calculated energy gap depends on the input wave functions being used. Here, we report the inverse quantum Fourier transformation based QPDE with $N_a$ of ancillary qubits, which allows us to compute the difference of eigenenergies based on the single-shot projective measurement. As a proof-of-concept demonstrations, we report numerical experiments for the singlet--triplet energy gap of hydrogen molecule and the vertical excitation energies of halogen-substituted methylenes (CHF, CHCl, CF$_2$, CFCl and CCl$_2$) and formaldehyde (HCHO).

description: Objectives: Validation of choroidal thickness and other biometrics measured by spectral domain optical coherence tomography (SD-OCT) in predicting lacquer cracks formation in highly myopic eyes.
Methods: Patients with a refractive error worse than −8 diopters and moderate myopic maculopathy were recruited into two groups based on the presence or absence of lacquer cracks (36 eyes without and 33 eyes with lacquer cracks). Choroidal thickness, refractive error, and axial length were measured and subjected to receiver operating characteristic curve analysis to identify the optimal cutoff values at predicting lacquer crack formation. The width of the retinal pigment epithelium (RPE), RPE to the inner segment/outer segment line, RPE to the external limiting membrane were also measured and compared to the subfoveal choroidal thickness to assess their relationships as potential markers of lacquer crack formation.
Results: Lacquer crack is associated with decreased choroidal thickness, lower best-corrected visual acuity, longer axial length and higher refractive errors. Choroidal thickness has the strongest association with lacquer crack formation versus axial length and refractive error. In eyes with lacquer cracks, stellate lacquer cracks are associated with thinner choroidal thickness compared to eyes with linear lacquer cracks. Subfoveal choroidal thickness less than the width of the retinal pigment epithelium to the inner segment/outer segment line is also associated with lacquer crack formation (sensitivity 78.8%, specificity 88.3%, and accuracy 81.2%).
Conclusions: This study suggests that choroidal thickness and other SD-OCT measurements could be employed clinically to predict the development and severity of lacquer cracks in patients with high myopia.
1d compression creep behaviour of kaolinite and bentonite clay

Publisher: name: University of Calgary
Year: 2011

description: Bibliography: p. 113-121
description: Creep mechanisms and factors influencing the creep in clay soils are not yet well understood due to the complex structure of clay matrix. An experimental program was conducted to investigate the parameters affecting the creep behaviour. One-dimensional single stage, stepwise and overloaded-unloaded compression creep tests were conducted using standard oedometer apparatus on kaolinite and bentonite clay samples. Single and radial drainage conditions with different pore fluids were considered. Required creep stress levels were achieved using instantaneous loading increments. Effects of stress level, stress history, pore fluid chemistry, fabric structure, drainage condition and mineral compositions of clay on creep behaviour were studied based on the experimental results. Drainage condition exhibited insignificant influence on creep. Creep mechanisms were explained as a combined effect of sliding of clay particles at their contacts and deformation of particle itself. Compression of micro pores during the creep is negligible. Developed model successfully describes the creep behaviour interims of viscosity.

description: Background: Urban landscape elements, particularly trees, have the potential to affect airflow, air quality, and production of aeroallergens. Several large-scale urban tree planting projects have sought to promote respiratory health, yet evidence linking tree cover to human health is limited.
Objectives: We sought to investigate the association of tree canopy cover with subsequent development of childhood asthma, wheeze, rhinitis, and allergic sensitization.
Methods: Birth cohort study data were linked to detailed geographic information systems data characterizing 2001 tree canopy coverage based on LiDAR (light detection and ranging) and multispectral imagery within 0.25 km of the prenatal address. A total of 549 Dominican or African-American children born in 1998–2006 had outcome data assessed by validated questionnaire or based on IgE antibody response to specific allergens, including a tree pollen mix.
Results: Tree canopy coverage did not significantly predict outcomes at 5 years of age, but was positively associated with asthma and allergic sensitization at 7 years. Adjusted risk ratios (RRs) per standard deviation of tree canopy coverage were 1.17 for asthma (95% CI: 1.02, 1.33), 1.20 for any specific allergic sensitization (95% CI: 1.05, 1.37), and 1.43 for tree pollen allergic sensitization (95% CI: 1.19, 1.72).
Conclusions: Results did not support the hypothesized protective association of urban tree canopy coverage with asthma or allergy-related outcomes. Tree canopy cover near the prenatal address was associated with higher prevalence of allergic sensitization to tree pollen. Information was not available on sensitization to specific tree species or individual pollen exposures, and results may not be generalizable to other populations or geographic areas.
Effects of mesalamine on adherent-invasive escherichia coli
Creators: name: Vanderploeg, Rachel Elisabeth
Publisher: name: University of Calgary

description: Bibliography: p. 69-75.
description: Mesalamine (5ASA) has been used for many years as a primary IBD treatment, yet the mechanism of action is not fully understood. The drug is targeted to the distal gut, thereby exposing bacteria to high concentrations of 5ASA. Considering the specific association of adherent-invasive Escherichia coli (AIEC) with this condition, we hypothesized that the therapeutic effects of 5ASA are mediated through influences on AIEC. Here, we show that 5ASA does not inhibit the growth of AIEC, but decreases AIEC's adherence to and invasion of intestinal epithelial cells. 5ASA treatment prevents the increase in adherence normally seen in inflammatory conditions. This is not due to a change in AIEC motility. 5ASA treatment increases AIEC's virulence gene (jimH,fimAv, ibeA, ompA) mRNA expression but that result did not correlate to an increase in pili expression. 5ASA affects AIEC making the bacteria less virulent, which could contribute to the therapeutic effect of 5ASA.

description: What does it mean to live well? Philosophers and theorists have described the “good life” for thousands of years as the pursuit of happiness and success - living well. Today, Americans spend over 90% of their time indoors and in traffic. Whether an individual is indoors or outdoors, their bodies are continuously reacting to the queues of the surrounding environments. Indoor air quality, exposure to natural daylight, and proximity to views are just some of the triggers that influence a building occupant’s mood and wellness. With time being limited during the week, it’s often hard to maintain positive states of mental, physical, and occupational wellness on a daily basis. Through the exploration of space and connection to building occupant well-being, the goal is to redefine the daily lifestyles of Washington D.C. residents and employees through mixed-use development.
