description: We consider the ordered and disordered dynamics for monolayers of rolling self-interacting particles with an offset center of mass and a non-isotropic inertia tensor. The rolling constraint is considered as a simplified model of a very strong, but rapidly decaying bond with the surface, preventing application of the standard tools of statistical mechanics. We show the existence and nonlinear stability of ordered lattice states, as well as disturbance propagation through and chaotic vibrations of these states. We also investigate the dynamics of disordered gas states and show that there is a surprising and robust linear connection between distributions of angular and linear velocity for both lattice and gas states, allowing to define the concept of temperature.

description: Ultraluminous X-ray sources (ULXs) are some of the most enigmatic X-ray bright sources known to date. It is generally accepted that they cannot host black holes as large as those associated with active galaxies, but they appear to be significantly more luminous than their better understood Galactic X-ray binary (XRB) cousins, while displaying an intriguing combination of differences and similarities with them. Through studying large, representative samples of these sources we may hope to enhance our understanding of them. To this end, we derive a large catalogue of 650 X-ray detections of 470 ULX candidates, located in 238 nearby galaxies, by cross correlating the 2XMM Serendipitous Survey with the Third Reference Catalogue of Bright Galaxies. The presented dedicated catalogue offers a significant improvement over those previously published both in terms of number and the contribution of background contaminants, e.g. distant quasars, which we estimate to be at most 24 per cent, but more likely ~17 per cent. To undertake population studies, we define a `complete' sub-sample of sources compiled from observations of galaxies with sensitivity limits below 10^39 erg/s. The luminosity function of this sample is consistent with a simple power-law. Although we do not find any statistical requirement for a high luminosity cut-off, as has been reported previously, we are not able to rule out its presence. Also, we find that the number of ULXs per unit galaxy mass decreases with increasing galaxy mass for ULXs associated with spiral galaxies, in broad agreement with previous results, but is consistent with being constant with galaxy mass for sources associated with elliptical galaxies.

description: We determine hidden conformal symmetries behind the evolution equations of black hole perturbations in a vector-tensor theory of gravity. Such hidden symmetries are valid everywhere in the exterior region of a spherically symmetric, asymptotically flat black hole geometry. They allow us to factorize second order operators controlling the black hole perturbations into a product of two commuting first order operators. As a consequence, we are able to analytically determine the most general time-dependent solutions for the black hole perturbation equations. We focus on solutions belonging to a highest weight representation of a conformal symmetry, showing that they correspond to quasi-bound states with an ingoing behaviour into the black hole horizon, and exponential decay at spatial infinity. Their time-dependence is characterized by purely imaginary frequencies, with imaginary parts separated by integer numbers, as the overtones of quasi-normal modes in General Relativity.

description: We present observational evidence for oscillations of magnetic flux density in the quiet areas of the Sun. The majority of magnetic fields on the solar surface have strengths of the order of or lower than the equipartition field (300-500 G). This results in a myriad of magnetic fields whose evolution is largely determined by the turbulent plasma motions. When granules evolve they squash the magnetic field lines together or pull them apart. Here we report on the periodic deformation of the shapes of features in circular polarization observed at high resolution with Sunrise. In particular, we note that the area of patches with constant magnetic flux oscillates with time, which implies that the apparent magnetic field intensity oscillates in antiphase. The periods associated to this oscillatory pattern is compatible with the granular life-time and change abruptly, which suggests that these oscillations might not correspond to characteristic oscillatory modes of magnetic structures, but to the forcing by granular motions. In one particular case, we find three patches around the same granule oscillating in phase, which means that the spatial coherence of these oscillations can reach 1600 km. Interestingly, the same kind of oscillatory phenomenon is found also in the upper photosphere.

Strong-coupling superconductivity of the Heusler-type compound ScAu2Al: Ab-initio studies

description: The ScAu$_2$Al superconducting Heusler-type compound was recently characterized to have the highest critical temperature of $T_c = 5.12$ K and the strongest electron-phonon coupling among the Heusler family. In this work, the electronic structure, phonons, electron-phonon coupling, and superconductivity of ScAu$_2$Al are studied using \textit{ab initio} calculations. The spin-orbit coupling significantly changes the electronic structure removing the van Hove singularity from the vicinity of the Fermi level. In the phonon spectrum, low frequency acoustic modes, additionally softened by the spin-orbit interaction, strongly couple with electrons, leading to the electron-phonon coupling constant $λ=1.25$, a record high among Heuslers. The density functional theory for superconductors is then used to analyze superconducting {state in this two-band superconductor}. The effect of spin fluctuations (SF) on superconductivity is also analyzed. The calculated critical temperatures of $T_c = 5.16$ K (4.79 K with SF) agree very well with the experiment, confirming the electron-phonon mechanism of superconductivity and showing a weak spin-fluctuations effect. The superconducting gaps formed on two Fermi surface sheets exhibit moderate anisotropy. Their magnitudes confirm the strong coupling regime, as the reduced average values are $2Δ_1/k_BT_c \simeq 4.1$ and $2Δ_2/k_BT_c \simeq 4.3$. Anisotropy of the gaps and large spread in their values significantly affect the calculated quasiparticle density of states.

description: Two-dimensional crystals of trapped ions are a promising system with which to implement quantum simulations of challenging problems such as spin frustration. Here, we present a design for a surface-electrode elliptical ion trap which produces a 2-D ion crystal and is amenable to microfabrication, which would enable higher simulated coupling rates, as well as interactions based on magnetic forces generated by on-chip currents. Working in an 11 K cryogenic environment, we experimentally verify to within 5% a numerical model of the structure of ion crystals in the trap. We also explore the possibility of implementing quantum simulation using magnetic forces, and calculate J-coupling rates on the order of 10^3 / s for an ion crystal height of 10 microns, using a current of 1 A.

Mechanisms of carbon mineralization from the pore to field scale : implications for carbon dioxide sequestration
Creators: name: Harrison, Anna Lee
Publisher: name: University of British Columbia
Year: 2014

description: Innovative technologies to stabilize atmospheric CO₂ concentrations are essential in order to mitigate the harmful effects of anthropogenic greenhouse gas (GHG) emissions on the global climate system. Mineralization of carbon in solid, stable carbonate minerals through reaction of CO₂ with Mg-rich mining wastes is a promising CO₂ sequestration strategy that offers the potential to render certain mines GHG neutral. Here, the physical and chemical controls on rates of and capacity for CO₂ sequestration in systems representative of mine tailings are examined from the mineral-fluid interface to field scale using a combination of experimental techniques. These experimental data and existing field data are used to develop a comprehensive reactive transport model that captures the processes governing carbon mineralization in the shallow subsurface. Stirred batch reactor, microfluidic pore scale, and decimeter to meter scale column carbonation experiments using brucite [Mg(OH)2] revealed that the primary controls on carbonation include the rate of CO₂ supply, the distribution of the reactive phase, the mineral grain size/surface area, and the availability and distribution of water. The rate-limiting step during carbonation varied from CO₂ supply to mineral dissolution depending on the experimental variables. Surface passivation and water-limited reaction resulted in a highly non-geometric evolution of reactive surface area. The extent of reaction was also limited at high water content because viscous fingering of the gas streams supplied to the columns resulted in narrow zones of highly carbonated material, but left a large proportion of brucite unreacted. More robust predictions of the CO₂ sequestration rate and capacity that can be expected at the field scale are possible due to the incorporation of water consumption, water-limited reactivity, and surface passivation functions into the reactive transport code, MIN3P. This research imparts a better understanding of fundamental mechanisms and chemical processes relevant to CO₂ sequestration in mine tailings, with implications for mineral carbonation in other settings that have greater CO₂ sequestration capacity, such as shallow subsurface formations with similar mineralogy. Aspects of this research, such as water-limited reactivity, have broader implications for reactive transport processes in the vadose zone in general, including mineral weathering and groundwater remediation.

description: We present a new formulation of the jamming phase diagram for a class of glass-forming fluids consisting of spheres interacting via finite-ranged repulsions at temperature $T$, packing fraction $ϕ$ or pressure $p$, and applied shear stress $Σ$. We argue that the natural choice of axes for the phase diagram are the dimensionless quantities $T/pσ^3$, $pσ^3/ε$, and $Σ/p$, where $T$ is the temperature, $p$ is the pressure, $Σ$ is the stress, $σ$ is the sphere diameter, $ε$ is the interaction energy scale, and $m$ is the sphere mass. We demonstrate that the phase diagram is universal at low $pσ^3/ε$; at low pressure, observables such as the relaxation time are insensitive to details of the interaction potential and collapse onto the values for hard spheres, provided the observables are non-dimensionalized by the pressure. We determine the shape of the jamming surface in the jamming phase diagram, organize previous results in relation to the jamming phase diagram, and discuss the significance of various limits.

description: Next-generation large-scale neutrino detectors, from Eos, at the 1 tonne scale, to Theia, at the 10s-of-ktonne scale, will utilize differences in both the scintillation and Cherenkov light emission for different particle species to perform background rejection. This manuscript presents measurements of the scintillation light yield and emission time profile of water-based liquid scintillator samples in response to $α$ radiation. These measurements are used as input to simulation models used to make predictions for future detectors. In particular, we present the timing-based particle identification achievable in generic water-based scintillator detectors at the 4 tonne, 1 ktonne, and 100 ktonne scales. We find that $α$/$β$ discrimination improves with increasing scintillation concentration and we identify better than 80% $α$ rejection for 90% $β$ acceptance in 10% water-based liquid scintillator, at the 4 tonne scale.

description: The growth of e-commerce has seen a surge in popularity of platforms like Amazon, eBay, and Taobao. This has given rise to a unique shopping behavior involving baskets - sets of items purchased together. As a less studied interaction mode in the community, the question of how should shopping basket complement personalized recommendation systems remains under-explored. While previous attempts focused on jointly modeling user purchases and baskets, the distinct semantic nature of these elements can introduce noise when directly integrated. This noise negatively impacts the model's performance, further exacerbated by significant noise (e.g., a user is misled to click an item or recognizes it as uninteresting after consuming it) within both user and basket behaviors. In order to cope with the above difficulties, we propose a novel Basket recommendation framework via Noise-tolerated Contrastive Learning, named BNCL, to handle the noise existing in the cross-behavior integration and within-behavior modeling. First, we represent the basket-item interactions as the hypergraph to model the complex basket behavior, where all items appearing in the same basket are treated as a single hyperedge. Second, cross-behavior contrastive learning is designed to suppress the noise during the fusion of diverse behaviors. Next, to further inhibit the within-behavior noise of the user and basket interactions, we propose to exploit invariant properties of the recommenders w.r.t augmentations through within-behavior contrastive learning. A novel consistency-aware augmentation approach is further designed to better identify noisy interactions with the consideration of the above two types of interactions. Our framework BNCL offers a generic training paradigm that is applicable to different backbones. Extensive experiments on three shopping transaction datasets verify the effectiveness of our proposed method.

description: We have employed the improved Peierls-Nabarro (P-N) equation to study the properties of 1/2<110> edge dislocation in {111} plane in FCC metals Al, Cu, Ir, Pd, and Pt. The generalized-stacking-fault energy (GSFE) surface entering the equation is calculated by using first-principles density functional theory (DFT). The accuracy of the method has been tested by calculating values for various stacking fault energies which favorably compare with the previous theoretical and experimental results. The core structures, including the core widths both of the edge and screw components, dissociation behavior for edge dislocations have been investigated. The dissociated distance between two partials for Al in our calculation agrees well with the values obtained from the numeric simulation with DFT and molecular dynamics simulation, as well as experiment. Our calculations show that it is preferred to create partial dislocation in Cu, and to be easily observed full dislocation in Al, Ir, Pd, and especially Pt.

description: We study the Landau quantization of the electronic spectrum for graphene bilayers that are rotationally faulted to produce periodic superlattices. Commensurate twisted bilayers exist in two families distinguished by their sublattice exchange parity. We show that these two families exhibit distinct Landau quantized spectra distinguished both by the interlayer coupling of their zero modes and by an amplitude modulation of their spectra at energies above their low energy interlayer coherence scales. These modulations can provide a powerful experimental probe of the magnitude of a weak coherence splitting in a bilayer and its low energy mass structure.

description: We present an analysis of the extended mid-infrared (MIR) emission of the Great Observatories All-Sky LIRG Survey (GOALS) sample based on 5-15um low resolution spectra obtained with the IRS on Spitzer. We calculate the fraction of extended emission as a function of wavelength for the galaxies in the sample, FEE_lambda. We can identify 3 general types of FEE_lambda: one where it is constant, one where features due to emission lines and PAHs appear more extended than the continuum, and a third which is characteristic of sources with deep silicate absorption at 9.7um. More than 30% of the galaxies have a median FEE_lambda larger than 0.5 implying that at least half of their MIR emission is extended. Luminous Infrared Galaxies (LIRGs) display a wide range of FEE in their warm dust continuum (0<=FEE_13.2um<=0.85). The large values of FEE_13.2um that we find in many LIRGs suggest that their extended MIR continuum emission originates in scales up to 10kpc. The mean size of the LIRG cores at 13.2um is 2.6kpc. However, once the LIR of the systems reaches the threshold of ~10^11.8Lsun, all sources become clearly more compact, with FEE_13.2um<=0.2, and their cores are unresolved. Our estimated upper limit for the core size of ULIRGs is less than 1.5kpc. The analysis indicates that the compactness of systems with LIR>~10^11.25Lsun strongly increases in those classified as mergers in their final stage of interaction. The FEE_13.2um is also related to the contribution of an active galactic nucleus (AGN) to the MIR. Galaxies which are more AGN-dominated are less extended, independently of their LIR. We finally find that the extent of the MIR continuum emission is correlated with the far-IR IRAS log(f_60um/f_100um) color. This enables us to place a lower limit to the area in a galaxy from where the cold dust emission may originate, a prediction which can be tested soon with the Herschel Space Telescope.

McLerran-Venugopolan(MV) model and iterative solution of DGLAP equation in the double leading log approximation for small x gluon distribution function were used to derive the new formula for initial chromofield energy density. This initial chromofield energy is distributed among color neutral clusters or strings of different length. This strings are stretched by receding nucleus. From the proposed mechanism of string fragmentation or color field decay based on exact solution of Dirac equation in the different finite volume, the new formulae for esimated baryon kinetic energy loss and rapidity spectrum of produced partons were derived.

description: IC 10 is the nearest starburst irregular galaxy remarkable for its anomalously high number of WR stars. We report the results of an analysis of the emission spectra of HII-regions ionized by star clusters and WR stars based on observations made with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences using MPFS field spectrograph and SCORPIO focal reducer operating in the slit spectrograph mode. We determine the masses and ages of ionizing star clusters in the violent star-forming region of the galaxy in terms of the new evolutionary models of emission-line spectra of HII-regions developed by Martin-Manjon et al. (2010). We estimate the amount of stars needed to ionize the gas in the brightest HII-region HL 111 and report new determinations of oxygen abundance in HII regions.

description: We present an H-band image of FS Tauri, a 0.2"-separated classical T Tauri binary system, taken with the Coronagraphic Imager with Adaptive Optics on the Subaru Telescope. This new image, combined with Hubble Space Telescope / Advanced Camera for Surveys F606W-band polarimetric images, shows that the binary has complicated circumbinary features, including a circumbinary disk, western and eastern arm-like structures, and two cavities at the northeast and southwest. The circumbinary disk is 630 AU in radius and the southeast side of the disk is bright in the H-band. The brightness ratio (southeast/northwest) is 1.6. A single Rayleigh-like scattering model indicates that the disk is inclined by 30 degree to 40 degree and that the southeast side corresponds to the near side along our line of sight. The H-band surface brightness of the southeast side decreases as r^(-1.9) from 15.2 mag arcsec^-2 to 16.8 mag arcsec^-2. The outer portion of the disk is possibly more flared than its inner portion. The weak centro-symmetric polarization pattern and redder F606W-H color (4.2 mag) of the southeast side are probably caused by multiple scattering events from the dust grains associated with the binary. The F606W-band image shows the bright northwest side of the disk in contrast with the H-band image. The F606W-H color of the northwest side is between 1.7 mag and 3.0 mag. We consider that Haro 6-5 B (FS Tauri B), 20" away, produces the neutral scattered light from the northwest side. This idea is supported by the polarization pattern of the northwest side, which is centro-symmetric with respect to Haro 6-5 B. The arms appear to encompass the western and eastern cavities, suggesting that the arms + cavity systems are created by a bipolar outflow from the binary. However, the direction of this outflow is inconsistent with that of outflows inferred from the circumbinary disk model.

description: The inclusive jet cross section is measured in pp collisions with a center-of-mass energy of 7 TeV at the LHC using the CMS experiment. The data sample corresponds to an integrated luminosity of 34 inverse picobarns. The measurement is made for jet transverse momenta in the range 18-1100 GeV and for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jet pT ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leading-order perturbative QCD predictions.
Variational studies of dressed quasiparticles' properties and their interactions with external potentials
Creators: name: Ebrahimnejad Rahbari, S. Hadi
Publisher: name: University of British Columbia
Year: 2014

description: In this thesis, we investigated the spectral properties of polaronic quasiparticles resulting from the coupling of a charge carrier to the bosonic excitations of ordered environments. Holstein polarons, describing an electron locally coupled to dispersionless phonons, and spin polarons in hole-doped antiferromagnets are considered. The Green's function of the Holstein polaron in a lattice with various kinds of impurities is calculated using the momentum average approximation. The main finding is that the scenario where the mere effect of the coupling to phonons is to enhance the electron's effective mass is incomplete as the phonons are found to also renormalize the impurity potential the polaron interacts with. This formalism is applied first to the case of a single impurity and the range of parameters where the polaron's ground state is localized is identified. The lifetime of the polaron due to scattering from weak but extended disorder is then studied and it is shown that the renormalization of the disorder potential leads to deviation of the strong coupling results from Fermi's golden rule's predictions. Motivated by the hole-doped cuprate superconductors, the motion of a hole in a two-dimensional Ising antiferromagnet and its binding to an attractive impurity is studied next, based on a variational scheme that allows for configurations with a certain maximum number of spin flips. The role of the magnetic sublattices in determining the symmetry of the resulting bound states is discussed. Next, a more realistic model describing a hole in a CuO₂ layer which retains the O explicitly, is considered. By neglecting the fluctuations of the Cu spins and using a variational principle similar to that of the previous chapter, a semi-analytic solution for the Green's function of the hole in an infinite 2D lattice is constructed. The resulting quasiparticle dispersion shows the proper ground state and other features observed in experiments. The lack of importance of the background spin fluctuations is justified based on the hole's ability to move on the O sublattice without disturbing the Cu spins. Finally, the model is generalized to gauge the importance of other relevant O orbitals.

description: Belgium, a neutral state, was forced into the First World War by a German ultimatum, a fact with considerable international resonance. The war had a deep impact on what was, in 1914, the most densely-populated country in the world. Most of Belgium came under German military occupation; the army was cut off from the home front; and the government was in exile, as were 8 percent of citizens. This constellation of occupation, front, and exile made for a specific array of war efforts. These efforts endured throughout the conflict. Yet, tensions arose, which would inflect the war’s aftermath.

description: Irrigation water is a risk factor in the transmission of verotoxigenic Escherichia coli (VTEC) to growing food plants. To date, there have been no systematic attempts to examine VTEC occurrence in surface waters used to irrigate crops in British Columbia. The objectives of this study were to determine the seasonal prevalence and characteristics of VTEC in surface waters and fresh produce grown in the Lower Mainland of British Columbia. Water samples (n=330) were collected from irrigation ditches and streams in four distinct watersheds between November 2012 – November 2013. Leafy vegetables (n=79) and berry fruits (n=26) were obtained from seven local farm markets during the summer. Detection and isolation of VTEC in water and produce rinses were performed using a novel hydrophobic grid membrane filtration-verotoxin immunoblot method. Prospective VTEC isolates were characterized by multiplex PCR to determine virulence gene profiles (eaeA, hlyA, vt₁ and vt₂), serotyping, antibiotic resistance profiling and genotyping by BOX-PCR. Fecal coliform and E. coli counts were obtained on Petrifilm™. VTEC were not recovered from 105 samples of produce but were found in 19.1% of surface water samples. Seasonal prevalence rates were significantly different (P < 0.05), ranging from 34.2% to 15.7% and 13.3%, in winter, spring/summer and fall months, respectively. BOX-PCR revealed that 100 of 528 VTEC isolates were unique, including 3 of serotypes O157:H7/O157:NM, 16 of non-O157 “priority” serogroups O26, O103 and O111, and 81 from 32 additional serotypes with 10 distinct virulence gene profiles. Multiple antibiotic resistance was observed in 16.3% of isolates (n=104), and resistance to florfenicol (27.9%), streptomycin (13.5%), tetracycline (12.5%) and ampicillin (9.6%) was common. Fecal coliform and E. coli counts did not correlate with VTEC occurrence, and isolates were recovered from 21.7% of water samples with no E. coli detected. In conclusion, VTEC were not recovered from fresh produce despite their recurrence in surface waters. The diversity of VTEC recovered from surface waters suggests the need for further research to identify sources of contamination and factors leading to persistence. Water quality methods based on the presence of indicator species may not reliably predict the risk of contamination with VTEC.

description: This article concerns the Weyl series of spectral functions associated with the Dirichlet Laplacian in a $d$-dimensional domain with a smooth boundary. In the case of the heat kernel, Berry and Howls predicted the asymptotic form of the Weyl series characterized by a set of parameters. Here, we concentrate on another spectral function, the (normalized) heat content. We show on several exactly solvable examples that, for even $d$, the same asymptotic formula is valid with different values of the parameters. The considered domains are $d$-dimensional balls and two limiting cases of the elliptic domain with eccentricity $ε$: A slightly deformed disk ($ε\to 0$) and an extremely prolonged ellipse ($ε\to 1$). These cases include 2D domains with circular symmetry and those with only one shortest periodic orbit for the classical billiard. We analyse also the heat content for the balls in odd dimensions $d$ for which the asymptotic form of the Weyl series changes significantly.

description: The Ottoman mobilization of manpower in August 1914 not only involved men being called to arms, but also women being mobilized to work in the industrial, service and agricultural sectors. Female labor was needed not only to supply a large number of soldiers with equipment, uniforms, shoes, food and care, but also to replace the enlisted men in the factories, workshops, offices, and fields.

description: Spectrum sensing technology is a crucial aspect of modern communication technology, serving as one of the essential techniques for efficiently utilizing scarce information resources in tight frequency bands. This paper first introduces three common logical circuit decision criteria in hard decisions and analyzes their decision rigor. Building upon hard decisions, the paper further introduces a method for multi-user spectrum sensing based on soft decisions. Then the paper simulates the false alarm probability and detection probability curves corresponding to the three criteria. The simulated results of multi-user collaborative sensing indicate that the simulation process significantly reduces false alarm probability and enhances detection probability. This approach effectively detects spectrum resources unoccupied during idle periods, leveraging the concept of time-division multiplexing and rationalizing the redistribution of information resources. The entire computation process relies on the calculation principles of power spectral density in communication theory, involving threshold decision detection for noise power and the sum of noise and signal power. It provides a secondary decision detection, reflecting the perceptual decision performance of logical detection methods with relative accuracy.

Manual wheelchair users : understanding participation and skill development.
Creators: name: Best, Krista Lynn
Publisher: name: University of British Columbia

description: Wheelchair skills, required for manual wheelchair (MWC) use, are strongly associated with independent mobility, physical activity, and participation. Training can improve mobility and participation in meaningful activities for MWC users, but strategies are required to enhance skill development. Peer-led self-efficacy interventions have been effective at enhancing skills in other clinical areas, and present a novel approach to MWC training that may enhance use. Purpose: develop an understanding of MWC use and current MWC training education and practices, and to explore and evaluate a novel approach to improving MWC use. Methods: secondary analysis of a national survey to determine physical activity levels in older wheelchair users; surveys of rehabilitation centres and universities to describe MWC training practices and curriculum; systematic review and meta-analyses to evaluate the effect of peer-led interventions on physical activity and self-efficacy; and a pilot randomized controlled trial to evaluate a peer-led MWC training program for improving wheelchair self-efficacy and wheelchair use. Results: Only 8% and 41% of older wheelchair users participated in physical and leisure activity, and wheelchair use was found to be a primary risk factor for low levels of participation. A description of current MWC training in practice showed that 78% of clinicians provided basic MWC mobility training, but only 12% taught the advanced skills needed to achieve optimal community participation. Nearly 80% of entry-to-practice programs included MWC skills training in curriculum; however, only 38% used a validated training program. In a broad review, self-efficacy interventions had a small effect on physical activity (Cohen’s d = 0.2) and self-management self-efficacy (Cohen’s d =0.2). Peer-led MWC training had a large effect on wheelchair use self-efficacy (Cohen’s d =0.8), wheelchair skills capacity (Cohen’s d =0.7) and satisfaction with participation (Cohen’s d = 0.7), and no effect on wheelchair skills performance or life-space mobility. Conclusion: wheelchair use increases risk of physical inactivity. This may be related to wheelchair skills training, which currently relies on clinicians. Self-efficacy enhanced interventions can promote behaviour change. Peer-led MWC training may augment existing training, enhance self-efficacy and promote increased MWC use, which may elicit health benefits that are associated with physical activity.
On the estimation of interaction parameters in weak measurements

description: Since weak measurements are known to produce measurement values that can be much larger than the maximal eigenvalues of the measured observable, it is an interesting question how this enhancement of the measurement signal relates to the sensitivity of quantum measurements as investigated in the field of quantum metrology. In this presentation, it is pointed out that the estimation of a small interaction parameter using weak measurements actually corresponds to standard quantum metrology, where the logarithmic derivatives of the final measurement probabilities are proportional to the corresponding weak values. The analysis of the general weak measurement formalism then shows that extreme weak values do not improve the sensitivity. Instead, all final measurements with real weak values have the same sensitivity as a final measurement of the eigenvalues. This result supports the view that real weak values can be interpreted as precise, zero uncertainty estimates of a quantum observable, despite their deviation from the eigenvalues of the corresponding operator.

description: New Zealand was a very loyal British dominion. At the outbreak of the First World War, the great majority of its populace unhesitatingly put its support behind the “mother country” in its hour of need. The very small number of pacifists who emerged publicly were punished harshly under emergency regulations quickly passed. The most dynamic dissent during the war came from those who opposed the introduction of military conscription in 1917. Objectors were punished under further emergency regulations, ranging from fines to long periods of imprisonment.

description: The main goal of the AEGIS experiment at the CERN Antiproton Decelerator is the test of fundamental laws such as the Weak Equivalence Principle (WEP) and CPT symmetry. In the first phase of AEGIS, a beam of antihydrogen will be formed whose fall in the gravitational field is measured in a Moire' deflectometer; this will constitute the first test of the WEP with antimatter.

description: We compute the circularly polarized signal from atmospheric molecular oxygen. Polarization of O2 rotational lines is caused by Zeeman effect in the Earth magnetic field. We evaluate the circularly polarized emission for various sites suitable for CMB measurements: South Pole and Dome C (Antarctica), Atacama (Chile) and Testa Grigia (Italy). An analysis of the polarized signal is presented and discussed in the framework of future CMB polarization experiments. We find a typical circularly polarized signal (V Stokes parameter) of ~ 50 - 300 μK at 90 GHz looking at the zenith. Among the other sites Atacama shows the lower polarized signal at the zenith. We present maps of this signal for the various sites and show typical elevation and azimuth scans. We find that Dome C presents the lowest gradient in polarized temperature: ~ 0.3 μK/\circ at 90 GHz. We also study the frequency bands of observation: around ν \simeq 100 GHz and ν \simeq 160 GHz we find the best conditions because the polarized signal vanishes. Finally we evaluate the accuracy of the templates and the signal variability in relation with the knowledge and the variability of the Earth magnetic field and the atmospheric parameters.

description: This article analyses Swiss migration policy and Switzerland’s role as a country of asylum from 1914 to 1918. Subsequent sections discuss the change in migration patterns; how political emigrants and refugees were dealt with; the role of exile communities; the establishment of new border controls and a Federal Immigration Authority; and eventually the discourse on "''Überfremdung''". This article argues that the war gave rise to new migratory patterns and a defensive outlook against foreigners in Switzerland. Furthermore, the state of war enabled the Swiss government to centralise migration control at the federal level.
