Publisher: name: Universität Paderborn

description: Lebensmittelversorgung erfolgt global und die geografische Lebensmittelherkunft kann den Stoffgehalt beeinflussen. Verzehrs- und Gehaltsdaten wurden genutzt, um in Standardszenarien die Exposition zu Stoffen über Lebensmittel zu bewerten. Zusätzliche Quellen gaben weitere Informationen zur Lebensmittelherkunft, was für Herkunftsszenarien genutzt wurde, um Expositionsschätzungen zu verfeinern. Der Herkunftseinfluss wurde nicht von Standardszenarien abgedeckt für Bromid aus Tomaten, da das Herkunftsszenario beruhend auf Tomatenvielverzehrern und höheren Gehalten aus italienischen Tomaten die höchste Exposition von 0.015 mg/Tag/kg KG ergab. Jedoch wurden Herkunftseinflüsse auch in Standardszenarien abgedeckt, da diese zur höchsten Schätzung führten basierend auf Vielverzehrern und hohen Gehalten für die Fallstudien Ethephon aus Ananas (0.9 g/Tag/kg KG), Aluminium aus Kiwi (0.02 mg/Woche/kg KG), Aluminium und Cadmium aus Kakaopulver (0.15 mg/Woche/kg KG and 0.4 g/Woche/kg KG). Deutsche Heringvielverzehrer waren der Summe an Dioxinen und dioxinähnlichen polychlorierten Biphenylen mit 26.5 pg WHO-2005-TEQ/kg KG/Woche ausgesetzt basierend auf Ostseeproben, während norwegische Hochverzehrer eine niedrigere Exposition von 6.5 pg WHO-2005-TEQ/kg KG/Woche hatten basierend auf Proben der Norwegischen See. Die Betrachtung der geografischen Lebensmittelherkunft verfeinerte Expositionsschätzungen für gewählte Fallstudien aber mehr Daten sind nötig für zukünftige Verbesserungen.
description: Food supply is organised globally and the geographical origin of food could influence substance concentrations. Consumption and concentration data were used to assess the dietary exposure to substances in standard scenarios. Additional resources gave further food origin information which was used for origin-related scenarios to refine exposure estimates. The impact of origin was not covered by standard scenarios for bromide from tomatoes, as the origin-related scenario based on high tomato consumers and higher concentrations in Italian tomatoes resulted in the highest exposure of 0.015 mg/day/kg BW. However, origin influences were covered by standard scenarios, as these resulted in the highest estimate based on high consumers and high concentrations for the case studies ethephon from pineapples (0.9 g/day/kg BW), aluminium from kiwifruits (0.02 mg/week/kg BW), aluminium and cadmium from cocoa powder (0.15 mg/week/kg BW and 0.4 g/week/kg BW). German high consumers of herring were exposed to the total sum of dioxins and dioxin-like polychlorinated biphenyls with 26.5 pg WHO-2005-TEQ/kg BW/week based on Baltic Sea samples while Norwegian high consumers had a lower exposure of 6.5 pg WHO-2005-TEQ/kg BW/week based on Norwegian Sea samples. Considering the geographical food origin refined exposure estimates for selected case studies but more data are needed for future improvements.

description: We present the galaxy stellar mass function (MF) and its evolution in clusters from z~0.8 to the current epoch, based on the WIde-field Nearby Galaxy-cluster Survey (WINGS) (0.0410^11 M' does not evolve, but below M*~10^10.8 M' the MF at high redshift is flat, while in the Local Universe it flattens out at lower masses. The population of M* = 10^10.2 - 10^10.8 M' galaxies must have grown significantly between z=0.8 and z=0. We analyze the MF of different morphological types (ellipticals, S0s and late-types), and find that also each of them evolves with redshift. All types have proportionally more massive galaxies at high- than at low-z, and the strongest evolution occurs among S0 galaxies. Examining the morphology-mass relation (the way the proportion of galaxies of different morphological types changes with galaxy mass), we find it strongly depends on redshift. At both redshifts, ~40% of the stellar mass is in elliptical galaxies. Another ~43% of the mass is in S0 galaxies in local clusters, while it is in spirals in distant clusters. To explain the observed trends, we discuss the importance of those mechanisms that could shape the MF. We conclude that mass growth due to star formation plays a crucial role in driving the evolution. It has to be accompanied by infall of galaxies onto clusters, and the mass distribution of infalling galaxies might be different from that of cluster galaxies. However, comparing with high-z field samples, we do not find conclusive evidence for such an environmental mass segregation. Our results suggest that star formation and infall change directly the MF of late-type galaxies in clusters and, indirectly, that of early-type galaxies through subsequent morphological transformations.

Random cascade models of multifractality : real-space renormalization and travelling-waves

description: Random multifractals occur in particular at critical points of disordered systems. For Anderson localization transitions, Mirlin and Evers [PRB 62,7920 (2000)] have proposed the following scenario (a) the Inverse Participation Ratios (I.P.R.) $Y_q(L)$ display the following fluctuations between the disordered samples of linear size $L$ : with respect to the typical value $Y^{typ}_q(L) = e^{\bar{\ln Y_q(L)}} \sim L^{- τ_{typ}(q)} $ that involve the typical multifractal spectrum $τ_{typ}(q)$, the rescaled variable $y=Y_q(L)/Y^{typ}_q(L) $ is distributed with a scale-invariant distribution presenting the power-law tail $1/y^{1+β_q}$, so that the disorder-averaged I.P.R. $\bar{Y_q(L)} \sim L^{- τ_{av}(q)} $ have multifractal exponents $τ_{av}(q) $ that differ from the typical ones $τ_{typ}(q)$ whenever $β_q<1$; (b) the tail exponents $β_q$ and the multifractal exponents are related by the relation $β_q τ_{typ}(q)=τ_{av}(q β_q)$. Here we show that this scenario can be understood by considering the real-space renormalization equations satisfied by the I.P.R. For the simplest multifractals described by random cascades, these renormalization equations are formally similar to the recursion relations for disordered models defined on Cayley trees and they admit travelling-wave solutions for the variable $(\ln Y_q)$ in the effective time $t_{eff}=\ln L$ : the exponent $τ_{typ}(q)$ represents the velocity, whereas the tail exponent $β_q$ represents the usual exponential decay of the travelling-wave tail. In addition, we obtain that the relation (b) above can be obtained as a self-consistency condition from the self-similarity of the multifractal spectrum at all scales. Our conclusion is thus that the Mirlin-Evers scenario should apply to other types of random critical points, and even to random multifractals occurring in other fields.

Evaluating the impact of the blood glucose test strips reimbursement limitations in the British Columbia PharmaCare plan on utilization, costs and health outcomes
Creators: name: Itiola, Ademola Joshua
Publisher: name: University of British Columbia
Year: 2024

description: Introduction: People living with diabetes and not using insulin may not derive clinically significant benefit from routine self-monitoring of their glucose level. In response to this evidence, the Government of British Columbia (BC) in January 2015 introduced a policy that restricted the quantity of blood glucose test strips (BGTS) reimbursable under BC PharmaCare plans as a means of reducing unnecessary healthcare spending. To date, the impact of this policy has not been evaluated in BC. Therefore, we conducted this study to examine the impact of the policy on utilization, costs, and health outcomes. Methods: To evaluate the impact of British Columbia’s BGTS reimbursement restriction policy, we identified a cohort of adults (≥ 18 years old) with diabetes between 2013 and 2019 using BC’s administrative data. We described trends of utilization and costs among individuals with at least one PharmaCare-eligible BGTS claim. We also estimated cost savings using interrupted time series analysis and determined level of policy adherence. Using interrupted time series analysis, we investigated longitudinal changes in average 1) physician visits, 2) all-cause hospitalizations, 3) emergency department visits for hypoglycemia and hyperglycemia and, 4) healthcare spending. Results: Over the 7-year study period, a total of 279.7 million BGTS were eligible for PharmaCare coverage, on which the government spent $124.3 million. Overall, we observed an immediate decline in the average utilization and PharmaCare expenditure on BGTS following policy implementation, with non-insulin users mostly responsible for this reduction. In addition to good policy adherence, we estimated that PharmaCare saved $15.5 million between 2015 and 2019 (95% confidence interval: $4.4 million, $26.6 million) due to this change. We also found that the policy was not associated with an increase in overall health services utilization, or an increase in overall healthcare spending over the longer term. Conclusion: Our evaluation suggests that the BGTS reimbursement restriction policy in BC resulted in significant cost savings without any attendant increase in health services utilization or worsening of health outcomes in the long term. This demonstrates that disinvestment can free up resources that could be channeled towards more beneficial interventions.

description: We study distance properties of a general class of random directed acyclic graphs (DAGs). In a DAG, many natural notions of distance are possible, for there exists multiple paths between pairs of nodes. The distance of interest for circuits is the maximum length of a path between two nodes. We give laws of large numbers for the typical depth (distance to the root) and the minimum depth in a random DAG. This completes the study of natural distances in random DAGs initiated (in the uniform case) by Devroye and Janson (2009+). We also obtain large deviation bounds for the minimum of a branching random walk with constant branching, which can be seen as a simplified version of our main result.

Running together, even when we're apart : seeking community, being 'connected', and consuming together
Creators: name: Couture, Jesse
Publisher: name: University of British Columbia
Year: 2021

description: This research is designed to glean insights and understandings into some of the ways that individuals seek out and experience community though sport and sporting practices. Drawing from findings yielded from an ethnographic study of the urban ‘run crew’ scene in Vancouver, B.C., this dissertation includes three distinct but interrelated case studies which each highlight how community is experienced, produced, and ‘consumed’ by runners – with a focus on both runners and running-related businesses that cater to runners. The first study focuses explicitly on the run crew scene in Vancouver, highlighting both how runners make sense of their participation and at once how this emergent subsect of contemporary running culture is often linked to consumption. The second study focuses on a web-based ‘social self-tracking’ platform called Strava – an app and social network commonly used by athletes to record and share the data they produce while self-tracking. I propose that while Strava can be a source of motivation and entertainment for its users, and even help to establish or strengthen social networks, the platform invites users to adopt and adapt to technologically-mediated surveillance strategies that encourage and reward displays of bodily self-discipline. Finally, the third study examines social media content produced by run crews and Strava during the early months of the COVID-19 pandemic and highlights how these local organizations and this global corporation each leveraged the technological affordances of Instagram to help maintain a sense of togetherness and connection while their members were adhering to social distancing. I propose that each functioned as cultural intermediaries with regard to the dissemination of health, physical activity, and pandemic-related information. Overall, this dissertation contributes to literatures on sport-based communities, running (sub) cultures, and digital self-tracking in the context of physical activity. Taken together, these studies offer insights into the nature and structure of community in the contemporary moment, and work to extend ways of thinking about the relationships people (desire to) have with one another, with physical activity, and with technology.

description: A highly asymmetric dynamic nuclear spin pumping is observed in a single self assembled InGaAs quantum dot subject to resonant optical pumping of the neutral exciton transition leading to a large maximum polarization of 54%. This dynamic nuclear polarization is found to be much stronger following pumping of the higher energy Zeeman state. Time-resolved measurements allow us to directly monitor the buildup of the nuclear spin polarization in real time and to quantitatively study the dynamics of the process. A strong dependence of the observed dynamic nuclear polarization on the applied magnetic field is found, with resonances in the pumping efficiency being observed for particular magnetic fields. We develop a model that fully accounts for the observed behaviour, where the pumping of the nuclear spin system is due to hyperfine-mediated spin flip transitions between the states of the neutral exciton manifold.

description: The HCN, HCO+, and HNC molecules are commonly used as tracers of dense star-forming gas in external galaxies, but such observations are spatially unresolved. Reliably inferring the properties of galactic nuclei and disks requires detailed studies of sources whose structure is spatially resolved. We compare the spatial distributions and abundance ratios of HCN, HCO+, and HNC in W49A, the most massive and luminous star-forming region in the Galactic disk, based on maps of a 2' (6.6 pc) field at 14" (0.83 pc) resolution of the J=4-3 transitions of HCN, H13CN, HC15N, HCO+, H13CO+, HC18O+ and HNC. The kinematics of the molecular gas in W49A appears complex, with a mixture of infall and outflow motions. Both the line profiles and comparison of the main and rarer species show that the main species are optically thick. Two 'clumps' of infalling gas appear to be at ~40 K, compared to ~100 K at the source centre, and may be ~10x denser than the rest of the outer cloud. Chemical modelling suggests that the HCN/HNC ratio probes the current gas temperature, while the HCN/HCO+ ratio and the deuterium fractionation were set during an earlier, colder phase of evolution. The data suggest that W49A is an appropriate analogue of an extragalactic star forming region. Our data show that the use of HCN/HNC/HCO+ line ratios as proxies for the abundance ratios is incorrect for W49A, suggesting the same for galactic nuclei. Our observed isotopic line ratios such as H13CN/H13CO+ approach our modeled abundance ratios quite well in W49A. The 4-3 lines of HCN and HCO+ are much better tracers of the dense star-forming gas in W49A than the 1-0 lines. Our observed HCN/HNC and HCN/HCO+ ratios in W49A are inconsistent with homogeneous PDR or XDR models, indicating that irradiation hardly affects the gas chemistry in W49A. Overall, the W49A region appears to be a useful template for starburst galaxies.

Year: 2021

description: This presentation will give an update about the ongoing work to study the ecophysiological response of the Cold-Water Coral Dendrophyllia cornigera to multiple anthropogenic stressors under global change scenarios (WP4.3). We have designed and set up an aquaria facility that allows for the control and manipulation of several water parameters (namely temperature, carbon dioxide and oxygen concentrations) in order to study their combined effects and possible interactions on the ecophysiological response of D. cornigera. The experimental design includes two scenarios: current in situ natural temperature, carbon dioxide and oxygen concentration values vs IPCC RCP 8.5 “business as usual” prediction, and allows for the performance of medium to long-term ecophysiological experiments. The results from the performed experiments will be an important contribution to better understand the vulnerability of deep benthic communities to global change.

description: We investigate the tensor form factors of the baryon octet within the framework of the chiral quark-soliton model, emphasizing those of the nucleon, taking linear 1/N_c rotational as well as linear m_s corrections into account, and applying the symmetry-conserving quantization. We explicitly calculate the tensor form factors H_{T}^{q}(Q^{2}) corresponding to the generalized parton distributions H_{T}(x,ξ,t). The tensor form factors are obtained for the momentum transfer up to Q^{2}\leq1\,\mathrm{GeV}^{2} and at a renormalization scale of 0.36\,\mathrm{GeV}^{2}. We find for the tensor charges δu=1.08, δd=-0.32, δs=-0.01 and discuss their physical consequences, comparing them with those from other models. Results for tensor charges for the baryon octet are also given.

Improving the torque density of C-GEN Direct Drive Axial Flux Air Cored Permanent Magnet Generator
Creators: name: Ubani, Okechukwu
Publisher: name: The University of Edinburgh
Year: 2021

description: In the energy sector, the fossil fuels available are being exhausted and to support the increase in energy demand and reduction of greenhouse gases, countries are looking towards renewable energy. Wind power offers many advantages, which explains why it's one of the fastest-growing energy source and it is expected to continue to flourish as countries seek to reduce their carbon footprint. The newer wind turbines are better at generating wind power, especially in variable wind speeds. They have bigger rotors, higher towers, and lighter blades which increases the capacity of the turbine, therefore, improving reliability and e ciency. Nevertheless, as wind turbines grow increasingly in size and weight, this can make it di cult to manufacture and to transport the generator as a whole. The C-GEN air-cored permanent magnet machine o ers many attractive advantages over existing generator technologies used for direct drive. It's modular concept makes it easy to assemble and disassemble for transportation, manufacture and repairs. The output power depends on the number of stages among other factors, which gives rise to the idea of stackability. This thesis lays out the concept and operating principles of Halbach arrays and applies it to a C-GEN Axial Flux Air-Cored Permanent Magnet Generator. The machine is analysed using analytical methods and 2D/3D FEA simulations. A conclusion of the undertaking is given with a brief discussion of possible design considerations in a bid to nd a highly torque-dense generator.

description: Inspired by a recent result of Davies and Pushnitski, we study resonance asymptotics of quantum graphs with general coupling conditions at the vertices. We derive a criterion for the asymptotics to be of a non-Weyl character. We show that for balanced vertices with permutation-invariant couplings the asymptotics is non-Weyl only in case of Kirchhoff or anti-Kirchhoff conditions, while for graphs without permutation numerous examples of non-Weyl behaviour can be constructed. Furthermore, we present an insight helping to understand what makes the Kirchhoff/anti-Kirchhoff coupling particular from the resonance point of view. Finally, we demonstrate a generalization to quantum graphs with nonequal edge weights.

Magnetic symmetry based predictions of kind of electrical polarization distribution in their volumes were used. It was found that magnetization distribution heterogeneity with any symmetry produces electrical polarization. Results were systemized in scope of micromagnetic structure chirality. It was shown that all 0-degree domain walls with time-noninvariant chirality have identical type of spatial distribution of the magnetization and polarization.

description: The very metal-poor star HE 0338-3945 shows a double-enhanced pattern of the neutron-capture elements. The study to this sample could make people gain a better understanding of s- and r-process nucleosynthesis at low metallicity. Using a parametric model,we find that the abundance pattern of the neutron-capture elements could be best explained by a binary system formed in a molecular cloud, which had been polluted by r-process material. The observed abundance pattern of C and N can be explained by an AGB model(Karakas & Lattanzio 2007), . Combing with the parameters obtained from Cui & Zhang (2006), we suggest that the initial mass of the AGB companion is most likely to be about 2.5Msun, which excludes the possibility of forming a type-1.5 supernova. By comparing with the observational abundance pattern of CS 22892-052, we find that the dominating production of O should accompany with the production of the heavy r-process elements of r+s stars. Similar to r-II stars, the heavy r-process elements are not produced in conjunction with all the light elements from Na to Fe group. The abundance pattern of the light and r-process elements for HE 0338-3945 is very close to the pattern of the r-II star CS 22892-052. So, we suggest that this star HE 0338-3945 should be a special r-II star.

description: We investigate proper scoring rules for continuous distributions on the real line. It is known that the log score is the only such rule that depends on the quoted density only through its value at the outcome that materializes. Here we allow further dependence on a finite number $m$ of derivatives of the density at the outcome, and describe a large class of such $m$-local proper scoring rules: these exist for all even $m$ but no odd $m$. We further show that for $m\geq2$ all such $m$-local rules can be computed without knowledge of the normalizing constant of the distribution.

description: Aims. We report the first study of the peculiar ring-like galaxy HRG 2304 (NED02),which was previously classified as a ring galaxy with an elliptical smooth ring. This object was selected to prove that it is a candidate for the Solitaire-type ring galaxies in an early stage of ring formation. The main goal of this work is to provide the spectral characteristics of the current object and its companion AM 1646-795 (NED01). Methods. The study is based on spectroscopic observations in the optical band to highlight the characteristics of this interacting galaxy. To investigate the star formation history of HRG 2304 we used the stellar population synthesis code STARLIGHT. The direct V and B broad band images were used to enhance some fine structures. Results. Along the entire long-slit signal, the spectra of HRG 2304 and its companion resemble that of an early-type galaxy. We estimated a heliocentric systemic redshift of z = 0.0415, corresponding to heliocentric velocities of 12449 km s-1 for HRG 2304 (NED02) and 12430 km s-1 for AM1646-795 (NED01). The spatial variation in the contribution of the stellar population components for both objects are dominated by an old stellar population 2x10^9 < t < 13x10^9 yr. The observed radial-velocity distribution and the fine structures around HRG 2304 suggest an ongoing tidal interaction of both galaxies. Conclusions.The spectroscopic results and the morphological peculiarities of HRG 2304 can be adequately interpreted as an ongoing interaction with the companion galaxy. Both galaxies are early-type, the companion is elliptical, and the smooth distribution of the material around HRG 2304 and its off-center nucleus in the direction of AM1646-795 (NED01) characterize HRG 2304 as a Solitaire-type galaxy candidate in an early stage of ring formation.

description: We have used an electro-optic technique to measure the position-dependent infrared absorption of holes injected into a thin crystal of the organic semiconductor, 6,13-bis(triisopropylsilylethynyl)-pentacene incorporated in a field-effect transistor. By applying square-wave voltages of variable frequency to the gate or drain, one can measure the time it takes for charges to accumulate on the surface, and therefore determine their mobility.

Simulation of diffusions by means of importance sampling paradigm

description: The aim of this paper is to introduce a new Monte Carlo method based on importance sampling techniques for the simulation of stochastic differential equations. The main idea is to combine random walk on squares or rectangles methods with importance sampling techniques. The first interest of this approach is that the weights can be easily computed from the density of the one-dimensional Brownian motion. Compared to the Euler scheme this method allows one to obtain a more accurate approximation of diffusions when one has to consider complex boundary conditions. The method provides also an interesting alternative to performing variance reduction techniques and simulating rare events.

Antineoplastic drug handling and potential for exposure among veterinarians
Creators: name: Senyk, Fiona
Publisher: name: University of British Columbia

description: Veterinary practices use antineoplastic (chemotherapeutic) drugs to treat various cancers in companion animals. The primary health concern with this is that veterinary staff largely use drugs designed for human treatments that can involuntarily harm those who handle them. Antineoplastic drugs are known to cause cancer and adverse reproductive health effects that have been largely studied in human health care settings. However, it is unknown the degree to which these drugs affect veterinary workers with respect to their unique protocols. This thesis furthers the understanding of antineoplastic drug use and exposure in veterinary practices. The thesis was comprised of two parts to address the research objectives. First, an online survey was administered in veterinary clinics to examine the drug preparation and administration practices, COVID-19 implications, training and guidelines, and personal protective equipment used with antineoplastic drugs. Second, surface wipe sampling was conducted to quantify the contamination on various surfaces, examine which drugs were found and where they were located within veterinary settings. The survey was completed by 80 participants in British Columbia and Minnesota. Twenty-four percent (19/80) reported that their clinic ever administered antineoplastic drugs. Eighty-two percent of participants who did not handle antineoplastic drugs referred animals to other practices. Sixty-eight percent (13/19) of respondents who administered antineoplastic drugs never received any formal safe handling training while 74% (14/19) of practices reported not following any specific guidelines on antineoplastic drug handling. Most clinics did not report significant change in their preparation and administration processes during the COVID-19 pandemic. In the surface wipe sampling, cyclophosphamide was the drug found most frequently for contamination. The surfaces most commonly contaminated included the floor where antineoplastic drugs were prepared and administered, door handles of antineoplastic storage and waste bins near antineoplastic drug administration and preparation, suggesting potential for exposure among workers. This thesis builds upon the limited existing literature to address how veterinary protocols affect exposure to antineoplastic drugs. Further research is recommended both on best practices specific to veterinary settings and on determining occupational exposure limits for antineoplastic drugs.

description: We study whether non-linear gravitational effects of relic neutrinos on the development of clustering and large-scale structure may be observable by weak gravitational lensing. We compute the density profile of relic massive neutrinos in a spherical model of a cluster of galaxies, for several neutrino mass schemes and cluster masses. Relic neutrinos add a small perturbation to the mass profile, making it more extended in the outer parts. In principle, this non-linear neutrino perturbation is detectable in an all-sky weak lensing survey such as EUCLID by averaging the shear profile of a large fraction of the visible massive clusters in the universe, or from its signature in the general weak lensing power spectrum or its cross-spectrum with galaxies. However, correctly modeling the distribution of mass in baryons and cold dark matter and suppressing any systematic errors to the accuracy required for detecting this neutrino perturbation is severely challenging.

Anomalous Polymer Dynamics Is Non-Markovian: Memory Effects and The Generalized Langevin Equation Formulation

description: Any first course on polymer physics teaches that the dynamics of a tagged monomer of a polymer is anomalously subdiffusive, i.e., the mean-square displacement of a tagged monomer increases as $t^α$ for some $α<1$ until the terminal relaxation time $τ$ of the polymer. Beyond time $τ$ the motion of the tagged monomer becomes diffusive. Classical examples of anomalous dynamics in polymer physics are single polymeric systems, such as phantom Rouse, self-avoiding Rouse, self-avoiding Zimm, reptation, translocation through a narrow pore in a membrane, and many-polymeric systems such as polymer melts. In this pedagogical paper I report that all these instances of anomalous dynamics in polymeric systems are robustly characterized by power-law memory kernels within a {\it unified} Generalized Langevin Equation (GLE) scheme, and therefore, are non-Markovian. The exponents of the power-law memory kernels are related to the relaxation response of the polymers to local strains, and are derived from the equilibrium statistical physics of polymers. The anomalous dynamics of a tagged monomer of a polymer in these systems is then reproduced from the power-law memory kernels of the GLE via the fluctuation-dissipation theorem (FDT). Using this GLE formulation I further show that the characteristics of the drifts caused by a (weak) applied field on these polymeric systems are also obtained from the corresponding memory kernels.

description: The complex optical properties of the iron-chalcogenide superconductor FeTe0.55Se0.45 with Tc=14K have been examined over a wide frequency range for light polarized in the Fe-Te(Se) planes above and below Tc. At room temperature the optical response may be described by a weakly-interacting Fermi liquid; however, just above Tc this picture breaks down and the scattering rate takes on a linear frequency dependence. Below Tc there is evidence for two gap features in the optical conductivity at Delta_1 ~ 2.5 meV and Delta_2 ~ 5.1 meV. Less than 20% of the free carriers collapse into the condensate for T << Tc, and this material is observed to fall on the universal scaling line for a BCS dirty-limit superconductor in the weak-coupling limit.

description: Over the last years, lattice calculations in pure Yang-Mills gauge theory seem to have come more or less to a consensus. The ghost propagator is not enhanced and the gluon propagator is positivity violating, infrared suppressed and non-vanishing at zero momentum. From an analytical point of view, several groups are agreeing with these results. Among them, the refined Gribov-Zwanziger (RGZ) framework also accommodates for these results. The question which rises next is, if our models hold the right form for the propagators, how to extract information on the real physical observables, i.e. the glueballs? How do the operators which represent glueballs look like? We review the current status of this matter within the RGZ framework.
