Electron-phonon interaction in Fe-based superconductors: Coupling of magnetic moments with phonons in LaFeAsO$_{1-x}$F$_{x}$

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The coupling of Fe magnetic moments in LaFeAsO$_{1-x}$F$_{x}$ with the As $A_{1g}$ phonon is calculated. We present first principles calculations of the atomic and electronic structure of LaFeAsO as a function of electron doping. We perform calculations using the virtual crystal approximation as well as supercell calculations with F substitutional impurity atoms. The results validate the virtual crystal approximation for the electronic structure near the Fermi level. Its is found that the electronic density of states at the Fermi level is maximum for x=0.125, enhancing the electron-phonon interaction. An additional increase of the electron-phonon parameter $λ$ is obtained if the coupling between the $A_{1g}$ phonon and the Fe magnetic moment is included. It is found that the electron-phonon interaction can be one order of magnitude larger than its value if no spin resolution is included in the calculation. The implications of these results on the superconducting transition are discussed

description: Data underlying published studies is difficult to find or access, which can hinder new scientific research. Currently, only about 20% of published papers[1] have their supporting data in discoverable and accessible repositories. The AGU, working with our partners (Dryad, CHORUS, ESIP, Wiley), and supported by NSF grant 2025364, will focus on improving guidance and workflows to properly manage, link, and track data and software references throughout the publication pipeline. The resulting best practices will serve as a resource for AGU editors, reviewers and authors and help advance data and software publication policies. Beyond the AGU, this work will serve as a model for linking information across funders, data repositories and publishers, and improving public access to research outputs. In this talk, current publication practices as they relate to the FAIR principles will be described, together with lessons learned, and how workflows and guidance are being improved.

Trockenreibprüfstand, mit Pellet/Scheibe-Geometrie unter
Berücksichtigung der spezifischen Anforderungen an den
Friktionskontakt im Kupplungssystem durchgeführt. Hierbei
besteht eine enge Kooperation mit dem Teilprojekt B2. Während in
Teilprojekt B2 Untersuchungen am Modellprüfstand erfolgen, sind
die Versuche in Teilprojekt A2 in einer weniger abstrahierten
Prüfstufe - an das reale Kupplungssystem angepasst -
angesiedelt [1].
Die experimentellen und konstruktiven Ergebnisse haben gezeigt,
dass ingenieurkeramische Werkstoffe ein hohes Potenzial im
Bereich der trockenlaufenden Friktionssysteme haben. Durch
geeignete Wahl der Systemreibpaarung und eine
keramikgerechte Konstruktion ist es nach ersten Abschätzungen
möglich, die Kfz-Kupplung um 53% kleiner zu bauen bzw. bei
gleicher Größe bis zu 180% höhere Drehmomente zu übertragen [2,
3]. Die Reibungszahlcharakteristik (fallende Reibungszahl über
Gleitgeschwindigkeit) ist im Hinblick auf Komfort (selbsterregte
Rupfschwingungen [4]) für die Kraftfahrzeugkupplung ungünstig.
Durch Randschichtmodifikationen der Keramikoberfläche in
Teilprojekt B2 wird die Reibungszahl auf ein Kupplungssystem
geeignete Charakteristik entwickelt.

description: Mimicking pristine 2D graphene, we revisit the BBTW model for 4D lattice QCD given in ref.[5] by using the hidden SU(5) symmetry of the 4D hyperdiamond lattice H_4. We first study the link between the H_4 and SU(5); then we refine the BBTW 4D lattice action by using the weight vectors λ_1, λ_2, λ_3, λ_4, λ_5 of the 5-dimensional representation of SU(5) satisfying Σ_iλ_i=0. After that we study explicitly the solutions of the zeros of the Dirac operator D in terms of the SU(5) simple roots α_1, α_2, α_3, α_4 generating H_4; and its fundamental weights ω_1, ω_2, ω_3, ω_4 which generate the reciprocal lattice H_4^\ast. It is shown, amongst others, that these zeros live at the sites of H_4^\ast; and the continuous limit D is given by ((id\surd5)/2) γ^\muk_μwith d, γ^μand k_μstanding respectively for the lattice parameter of H_4, the usual 4 Dirac matrices and the 4D wave vector. Other features such as differences with BBTW model as well as the link between the Dirac operator following from our construction and the one suggested by Creutz using quaternions, are also given. Keywords: Graphene, Lattice QCD, 4D hyperdiamond, BBTW model, SU(5) Symmetry.

The Structure of a Self-Gravitating Protoplanetary Disk and its Implications to Direct Imaging Observations

description: We consider the effects of self-gravity on the hydrostatic balance in the vertical direction of a gaseous disk and discuss the possible signature of the self-gravity that may be captured by the direct imaging observations of protoplanetary disks in future. In this paper, we consider a vertically isothermal disk in order to isolate the effects of self-gravity. The specific disk model we consider in this paper is the one with a radial surface density gap, at which the Toomre's $Q$-parameter of the disk varies rapidly in the radial direction. We calculate the vertical structure of the disk including the effects of self-gravity. We then calculate the scattered light and the dust thermal emission. We find that if the disk is massive enough and the effects of self-gravity come into play, a weak bump-like structure at the gap edge appears in the near-infrared (NIR) scattered light, while no such bump-like structure is seen in the sub-mm dust continuum image. The appearance of the bump is caused by the variation of the height of the surface in the NIR wavelength. If such bump-like feature is detected in future direct imaging observations, with the combination of sub-mm observations, it will bring us useful information about the physical states of the disk.

description: In this paper we study the drivers of change in individuals’ discount rates. Our panel dataset allows us to jointly consider socio-demographics, financial status and literacy, as well as job characteristics among the possible determinants. Our results suggest that individual time-preferences are not stable over time, especially among individuals who hold debts. Labour market variables do not play any direct role. A large part of the variation, however, is not explained by none these drivers. This supports the view that discount rates are related to an underlying unobservable individual trait.

description: Magnetic reconnection changes the magnetic field topology and powers explosive events in astrophysical, space and laboratory plasmas. For flares and coronal mass ejections (CMEs) in the solar atmosphere, the standard model predicts the presence of a reconnecting current sheet, which has been the subject of considerable theoretical and numerical modeling over the last fifty years, yet direct, unambiguous observational verification has been absent. In this Letter we show a bright sheet structure of global length (>0.25 Rsun) and macroscopic width ((5 - 10)x10^3 km) distinctly above the cusp-shaped flaring loop, imaged during the flare rising phase in EUV. The sheet formed due to the stretch of a transequatorial loop system, and was accompanied by various reconnection signatures that have been dispersed in the literature. This unique event provides a comprehensive view of the reconnection geometry and dynamics in the solar corona.

description: The Ultra-Fast Flash Observatory (UFFO) pathfinder is a space mission devoted to the measurement of Gamma-Ray Bursts (GRBs), especially their early light curves which will give crucial information on the progenitor stars and central engines of the GRBs. It consists of two instruments: the UFFO Burst Alert & Trigger telescope (UBAT) for the detection of GRB locations and the Slewing Mirror Telescope (SMT) for the UV/optical afterglow observations, upon triggering by UBAT. The UBAT employs a coded-mask γ/X-ray camera with a wide field of view (FOV), and is comprised of three parts: a coded mask, a hopper, and a detector module (DM). The UBAT DM consists of a LYSO scintillator crystal array, multi-anode photo multipliers, and analog and digital readout electronics. We present here the design and fabrication of the UBAT DM, as well as its preliminary test results.

description: Electron spin resonance (ESR) investigation of graphene nanoribbons (GNRs) prepared through longitudinal unzipping of multiwalled carbon nanotubes (MWCNTs) indicates the presence of C-related dangling bond centers, exhibiting paramagnetic features. ESR signal broadening from pristine or oxidized graphene nanoribbons (OGNRs) is explained in terms of unresolved hyperfine structure, and in the case of reduced GNRs (RGNRs), the broadening of ESR signal can be due to enhancement in conductivity upon reduction. The spin dynamics observed from ESR linewidth-temperature data reflect a variable range hopping (VRH) mechanism through localized states, consistent with resistance-temperature data.

Measurement of partial branching fractions of inclusive charmless B meson decays to K+, K0, and pi+

description: We present measurements of partial branching fractions of $B \rightarrow K^+ X$, $B \rightarrow K^0 X$, and $B \rightarrow π^+ X$, where $X$ denotes any accessible final state above the endpoint for B decays to charmed mesons, specifically for momenta of the candidate hadron greater than 2.34 (2.36) GeV for kaons (pions) in the B rest frame. These measurements are sensitive to potential new-physics particles which could enter the $b \rightarrow s(d)$ loop transitions. The analysis is performed on a data sample consisting of $383 \times 10^6$ $B \bar{B}$ pairs collected with the BaBar detector at the PEP-II $e^+e^-$ asymmetric energy collider. Our results are in agreement with standard model predictions and exclude large enhancements of the inclusive branching fraction due to sources of new physics.

description: We have serendipitously detected a strong O VI-bearing Lyman limit system at z_abs = 0.3558 toward the QSO J1009+0713 (z_em = 0.456) in our survey of low-redshift galaxy halos with the Hubble Space Telescope's Cosmic Origins Spectrograph. Its rest-frame equivalent width of W_r = 835 +/- 49 mA is the highest for an intervening absorber yet detected in any low-redshift QSO sightline, with absorption spanning 400 km s^-1 in its rest frame. HST/WFC3 images of the galaxy field show that the absorber is associated with two galaxies lying at 14 and 46 kpc from the QSO line of sight. The bulk of the absorbing gas traced by H I resides in two strong, blended component groups that possess a total logN(HI) = 18 - 18.8. The ion ratios and column densities of C, N, O, Mg, Si, S, and Fe, except the O VI, can be accommodated into a simple photoionization model in which diffuse, low-metallicity halo gas is exposed to a photoionizing field from stars in the nearby galaxies that propagates into the halo at 10% efficiency. We constrain the metallicity firmly within the range 0.1 - 1 Zsun, and photoionization modeling indirectly indicates a subsolar metallicity of 0.05 - 0.5 Zsun. The appearance of strong O VI and nine Mg II components and our review of similar systems in the literature support the "interface" picture of high-velocity O VI: the total strength of the O VI shows a positive correlation with the number of detected components in the low-ionization gas, however the total O VI column densities still far exceed the values expected from interface models for the number of detected clouds.

description: We demonstrate high-fidelity Zeeman qubit state detection in a single trapped 88 Sr+ ion. Qubit readout is performed by shelving one of the qubit states to a metastable level using a narrow linewidth diode laser at 674 nm followed by state-selective fluorescence detection. The average fidelity reached for the readout of the qubit state is 0.9989(1). We then measure the fidelity of state tomography, averaged over all possible single-qubit states, which is 0.9979(2). We also fully characterize the detection process using quantum process tomography. This readout fidelity is compatible with recent estimates of the detection error-threshold required for fault-tolerant computation, whereas high-fidelity state tomography opens the way for high-precision quantum process tomography.

description: We report preliminary results on the chiral and deconfinement aspects of the QCD transition at finite temperature using the Highly Improved Staggered Quark (HISQ) action on lattices with temporal extent of N_τ=6 and 8. The chiral aspects of the transition are studied in terms of quark condensates and the disconnected chiral susceptibility. We study the deconfinement transition in terms of the strange quark number susceptibility and the renormalized Polyakov loop. We made continuum estimates for some quantities and find reasonably good agreement between our results and the recent continuum extrapolated results obtained with the stout staggered quark action.

Mapping the distributions of two invasive plant species in urban areas with advanced remote sensing data
Creators: name: Chance, Curtis Matthew
Publisher: name: University of British Columbia
Year: 2016

description: Invasive plants are increasingly present in ecosystems, producing both positive and negative effects. Proactive management of plant invasions is critical to curbing their spreads, especially in urban areas which often act as centres of invasions. Therefore, municipalities require new tools to map invasions for both management and information. Remote sensing technologies provide opportunities to detect plant invasions over large areas at fine spatial resolutions. In Surrey, British Columbia, Canada, Himalayan blackberry (HB; Rubus armeniacus) and English ivy (EI; Hedera helix) are two understory invasive plants that can negatively influence native ecosystems and harm users of urban natural areas. Two remote sensing technologies, hyperspectral imagery and light detection and ranging (LiDAR) data, were utilized to map these two species across the entire area of Surrey. Analysis of spectral characteristics of HB and EI were used with hyperspectral imagery to examine the feasibility of spectrally detecting these species. Spectra were obtained from a ground-based handheld spectrometer from the two species and other common species in Surrey and processed through a spectral channel selection algorithm to identify key wavelengths for distinguishing these species. Once identified, a spectral classification routine used these wavelengths and training plots to detect HB and EI across open areas in Surrey. Results showed accuracies of 76.4% for HB and 80.0% for EI. Mapping HB and EI across all land covers of Surrey required detecting the two species in forested areas. Field plots, LiDAR-derived topographic and forest structure variables, hyperspectral data, a land cover classification, and a LiDAR-derived irradiance model were all used as inputs into random forest models to detect the species across the entire land base. Model accuracies ranged from 77.8% to 87.8%. Open areas were classified better than forested areas. EI was found more across the city than HB. The research in the thesis has advanced detection of invasive plants by demonstrating the feasibility of mapping understory invasions of EI and HB in urban areas at fine spatial resolutions and can form the basis for a future monitoring system using data acquired at regular intervals. Future work is recommended to enhance data collection and increase map specificity.

description: Development of radiation technology for the radiation-chemical studies in IPCE RAS started in 1945 and is inextricably linked to "Atomic project of the USSR". On February 1, 1946, samples of uranium irradiated on a cyclotron were transferred to the Special Laboratory of the Institute of Physical Chemistry for research on the release of plutonium. P.Ya. Glazunov, who worked under the direction of I. V. Kurchatov, played an extremely important role in the construction of Laboratory No. 6. At the radiation facilities on the subject of the "Atomic Project of the USSR" within the framework of laboratory No. 6, the founder of Russian radiation chemistry, N. A. Bach, who laid the foundations of radiation chemistry and radiation technologies, conducted radiation-chemical research. In subsequent years, the laboratory of P.Ya. Glazunov (since 1989, the laboratory is headed by Doctor of Technical Sciences Yu. S. Pavlov) successfully used radiation installations of various types and purposes: electronic accelerators VVU-1, U-12F, ELU-6E, U-003M, UELV-10-10-S-70; gamma installations with sources 60Сo MRX-γ-100, GUG-120, KPU-29, MGU-30; neutron generator NG-150, etc.

description: We compute g_{D* D pi} and g_{B* B pi} using a framework in which all elements are constrained by Dyson-Schwinger equation studies of QCD, and therefore incorporates a consistent, direct and simultaneous description of light- and heavy-quarks and the states they may constitute. We link these couplings with the heavy-light-meson leptonic decay constants, and thereby obtain g_{D* D pi}=15.9+2.1/-1.0 and g_{B* B pi}=30.0+3.2/-1.4. From the latter we infer \hat-g_B=0.37+0.04/-0.02. A comparison between g_{D* D pi} and g_{B* B pi} indicates that when the c-quark is a system's heaviest constituent, Lambda_{QCD}/m_c-corrections are not under good control.

description: Future giant liquid argon (LAr) time projection chambers (TPCs) require a purity of better than 0.1 parts per billion (ppb) to allow the ionised electrons to drift without significant capture by any electronegative impurities. We present a comprehensive study of the effects of electronegative impurity on gaseous and liquid argon scintillation light, an analysis of the efficacy of various purification chemicals, as well as the Liverpool LAr setup, which utilises a novel re-circulation purification system. Of the impurities tested - Air, O_2, H_2O, N_2 and CO_2 in the range of between 0.01 ppm to 1000 ppm - H_2O was found to have the most profound effect on gaseous argon scintillation light, and N_2 was found to have the least. Additionally, a correlation between the slow component decay time and the total energy deposited with 0.01 ppm - 100 ppm O_2 contamination levels in liquid argon has been established. The superiority of molecular sieves over anhydrous complexes at absorbing Ar gas, N_2 gas and H_2O vapour has been quantified using BET isotherm analysis. The efficiency of Cu and P_2O5 at removing O_2 and H_2O impurities from 1 bar N6 argon gas at both room temperature and -130 ^oC was investigated and found to be high. A novel, highly scalable LAr re-circulation system has been developed. The complete system, consisting of a motorised bellows pump operating in liquid and a purification cartridge, were designed and built in-house. The system was operated successfully over many days and achieved a re-circulation rate of 27 litres/hour and high purity.

description: This paper deals with the geometry of the space (GIT quotient) M_8 of 8 points in P^1, and the Gale-quotient N'_8 of the GIT quotient of 8 points in P^3. The space M_8 comes with a natural embedding in P^{13}, or more precisely, the projectivization of the S_8-representation V_{4,4}. There is a single S_8-skew cubic C in P^{13}. The fact that M_8 lies on the skew cubic C is a consequence of Thomae's formula for hyperelliptic curves, but more is true: M_8 is the singular locus of C. These constructions yield the free resolution of M_8, and are used in the determination of the "single" equation cutting out the GIT quotient of n points in P^1 in general. The space N'_8 comes with a natural embedding in P^{13}, or more precisely, PV_{2,2,2,2}. There is a single skew quintic Q containing N'_8, and N'_8 is the singular locus of the skew quintic Q. The skew cubic C and skew quintic Q are projectively dual. (In particular, they are surprisingly singular, in the sense of having a dual of remarkably low degree.) The divisor on the skew cubic blown down by the dual map is the secant variety Sec(M_8), and the contraction Sec(M_8) - - > N'_8 factors through N_8 via the space of 8 points on a quadric surface. We conjecture that the divisor on the skew quintic blown down by the dual map is the quadrisecant variety of N'_8 (the closure of the union of quadrisecant *lines*), and that the quintic Q is the trisecant variety. The resulting picture extends the classical duality in the 6-point case between the Segre cubic threefold and the Igusa quartic threefold. We note that there are a number of geometrically natural varieties that are (related to) the singular loci of remarkably singular cubic hypersurfaces.

description: Town planning requires conscious handling of the existing urban
structure and knowledge about its history. Only so planned
modifications and supplements can be integrated in a sustainable
manner into existing urban structures and have lasting effects.
Modern CAD environments offer basically the possibility of
supporting necessary planning process through additional
integrated tools. In the project 'Turban' CAD extensions were
developed additionally, providing planners and students with
fundamental tools for data-capture and analysis around the
temporal process from town developments.

description: The pseudogap state is one of the peculiarities of the cuprate high temperature superconductors. Here we investigate its presence in BaCo$_{x}$Fe$_{2-x}$As$_{2}$, a member of the pnictide family, with temperature dependent scanning tunneling spectroscopy. We observe that for under, optimally and overdoped systems the gap in the tunneling spectra always closes at the bulk T$_{c}$, ruling out the presence of a pseudogap state. For the underdoped case we observe superconducting gaps over large fields of view, setting a lower limit of tens of nanometers on the length scale of possible phase separated regions.

Turbulent fluctuations around Bjorken flow

description: We study the evolution of local event-by-event deviations from smooth average fluid dynamic fields, as they can arise in heavy ion collisions from the propagation of fluctuating initial conditions. Local fluctuations around Bjorken flow are found to be governed by non-linear equations whose solutions can be characterized qualitatively in terms of Reynolds numbers. Perturbations at different rapidities decouple quickly, and satisfy (after suitable coordinate transformations) an effectively two-dimensional Navier-Stokes equation of non-relativistic form. We discuss the conditions under which non-linearities in these equations cannot be neglected and turbulent behavior is expected to set in.

description: The self-assembly of a phenylalanine-substituted perylene bisimide (PBI) gelator in aqueous solution triggered using a pH switch is studied in detail. Spectroscopy, rheology and neutron scattering are used as complementary techniques to characterize the anisotropic structures forming in solution as the pH is decreased. We show that the pH-drop results in worm-like micelles and longer fibres being formed. Photocatalytic solutions are prepared by mixing the PBI solutions with a hydrogen evolution catalyst, Pt, and an electron hole scavenger, methanol, to study the photocatalytic potential of the PBI aggregates. We show, through electrochemical and spectroscopic studies, that illumination of PBI solutions results in the formation of the radical anion and dianion reduced species. We provide evidence that the reduced anisotropic PBI aggregates are active photocatalysts for driving the hydrogen evolution reaction. We expand the photocatalysis study to provide further intrinsic comparisons between self-assembled aggregates. A library of amino acid-substituted PBIs has been studied along with a range of solution compositions. We observe a wide range of photocatalytic activity between the different PBIs which can be related to the different packing arrangements. The addition of an anti-solvent also results in aggregation; at the pH values which show low photocatalytic activity, where there is a low concentration of aggregates, the addition of a solvent results in solvent-induced aggregation and a turn on in photocatalytic activity. This provides further evidence that self-assembly should be carefully considered when designing photocatalytic systems. We also show that when the PBI concentration is increased too high the amount of reduced PBI formed in solution reaches a plateau. Above 5 mg/mL PBI, the amount of radical anion formed during illumination remains the same. However, when lowering the PBI concentration, the rate of hydrogen evolution can dramatically increase. We find an optimum of ~150 μmol/g/h H2 for PBI-V at 0.1 mg/mL under white light illumination. Finally, we prepared a selection of gels using pH-switch and solvent-switch gelation methods and investigate their ability to recover their original morphology after shear. The networks of the gels before and after extrusion have been characterised in detail using confocal microscopy and neutron scattering. The solvent-switch gels are comprised of spherical domains which show good recovery after extrusion. On the other hand, the pH-switch gels which are comprised of a homogeneous dense fibrous network become fragmented after extrusion. This work highlights the need to consider the morphology of low molecular weight gels when used for extrusion-based applications such as 3D printing and drug delivery and proposes design considerations when developing new materials.

description: Connected to the Linear Collider project TESLA at DESY, studies
on the readout of TPCs based on the GEM-technology are ongoing.
For particle identication via dE/dx - measurement, a good
energy resolution is indispensable, and therefore losses of
primary electrons have to be avoided. It turned out, that in the
GEM transverse diffusion inside or close to the holes is a not
negligible reason for these losses. For Ar-CH4 90:10 and
TPC-like field configurations it was found, that when operated
in normal amplification mode, the Standard Geometry GEM should
not lose primaries, whereas for low gains, also when operated in
magnetic fields up to 5T, a GEM with larger pitch and hole
diameter would be necessary.

description: An atomic ion is trapped at the tip of a single-mode optical fiber in a cryogenic (8 K) surface-electrode ion trap. The fiber serves as an integrated source of laser light, which drives the quadrupole qubit transition of $^{88}$Sr$^+$. Through \emph{in situ} translation of the nodal point of the trapping field, the Gaussian beam profile of the fiber output is imaged, and the fiber-ion displacement, in units of the mode waist at the ion, is optimized to within $0.13\pm0.10$ of the mode center despite an initial offset of $3.30\pm0.10$. Fiber-induced charging at $125 μ$W is observed to be ${\sim}10$ V/m at an ion height of $670 μ$m, with charging and discharging time constants of $1.6\pm0.3$ s and $4.7\pm0.6$ s respectively. This work is of importance to large-scale, ion-based quantum information processing, where optics integration in surface-electrode designs may be a crucial enabling technology.

description: In this work we discuss the formation of zero energy vortex and chiral edge modes in a fermionic representation of the Kitaev honeycomb model. We introduce the representation and show how the associated Jordan-Wigner procedure naturally defines the so called branch cuts that connect the topological vortex excitations. Using this notion of the branch cuts we show how to, in the non-Abelian phase of the model, describe the Majorana zero mode structure associated with vortex excitations. Furthermore we show how, by intersecting the edges between Abelian and non-Abelian domains, the branch cuts dictate the character of the chiral edge modes. In particular we will see in what situations the exact zero energy Majorana edge modes exist. On a cylinder, and for the particular instances where the Abelian phase of the model is the full vacuum, we have been able to exactly solve for the systems edge energy eigensolutions and derive a recursive formula that exactly describes the edge mode structure. Penetration depth is also calculated and shown to be dependent on the momentum of the edge mode. These solutions also describe the overall character of the fully open non-Abelian domain and are excellent approximations at moderate distances from the corners.

Effect of NaOH solutions on planktonic bacteria, biofilms, and lipopolysaccharide
Creators: name: Mo, Anthony John
Publisher: name: University of British Columbia
Year: 2016

description: Background: Eradicating bacteria, biofilms and harmful by-products such as LPS from the root canal system is important in providing successful endodontic treatment. To date no irrigant or medicament used in endodontics has been able to completely eradicate bacteria in the root canal system or detoxify all LPS. Aim: It is proposed that a novel solution containing NaOH (Sodium hydroxide), Sodium dodecyl sulfate (SDS) and an alcohol may have unique disinfective properties against bacterial factors highly relevant in endodontic treatment. Materials and Methods: Combinations of the proposed solution were tested and compared to NaOCl (sodium hypochlorite) against 1- Planktonic E. faecalis in direct contact and quantified by CFU counts 2 - Polymicrobial biofilms in an open model exposed to solutions and visualized with CLSM (Confocal Laser Scanning Microscopy) 3 – LPS using a biofunctional assay, stimulating IL-1ß production in RAW 264.7 macrophages with treated LPS aliquots and analyzed by ELISA. Results: Planktonic killing tests with E. faecalis showed that NaOCl was more effective than NaOH solutions. With potency from highest to lowest as follows: 6% NaOCl, 2% NaOCl, NaOH/SDS/Propanol, NaOH/Propanol. Biofilm tests showed that NaOCl killed more biofilm bacteria, however NaOH/SDS combinations removed more biofilm mass. Results showed that LPS samples treated with either 6% or 2% NaOCl produced no IL-1ß. Samples treated with NaOH/SDS combinations produced inconsistent results regarding IL-1ß release due to inefficient dialysis removal of toxic irrigants. Conclusions: Results suggest that NaOCl remains the irrigant of choice as it is most effective in killing bacteria either planktonically or within biofilm systems. The results of this study suggest that NaOCl is indeed effective in LPS detoxification which is contrary to suggestions by several previous studies. NaOH/SDS combinations while less effective in killing, appear to remove more biofilm mass when compared to NaOCl. This may be attributed to the surfactant properties of SDS.

description: If Dark Energy introduces an acceleration in the universal expansion then large scale gravitational potential wells should be shrinking, causing a blueshift in the CMB photons that cross such structures (Integrated Sachs-Wolfe effect, [ISW]). Galaxy clusters are known to probe those potential wells. In these objects, CMB photons also experience inverse Compton scattering off the hot electrons of the intra-cluster medium, and this results in a distortion with a characteristic spectral signature of the CMB spectrum (the so-called thermal Sunyaev-Zel'dovich effect, [tSZ]). Since both the ISW and the tSZ effects take place in the same potential wells, they must be spatially correlated. We present how this cross ISW-tSZ signal can be detected in a CMB-data contained way by using the frequency dependence of the tSZ effect in multi frequency CMB experiments like {\it Planck}, {\em without} requiring the use of external large scale structure tracers data. We find that by masking low redshift clusters, the shot noise level decreases significantly, boosting the signal to noise ratio of the ISW--tSZ cross correlation. We also find that galactic and extragalactic dust residuals must be kept at or below the level of ~0.04 muK^2 at l=10, a limit that is a factor of a few below {\it Planck}'s expectations for foreground subtraction. If this is achieved, CMB observations of the ISW-tSZ cross correlation should also provide an independent probe for the existence of Dark Energy and the amplitude of density perturbations.
