    Abstract The long-term condition and potential radiological consequences of legacy radioactive waste stored in a RADON-type of near-surface disposal facility outside the city of Chişinău is of concern to the central government and health protection authorities of the Republic of Moldova. A 'zero alternative scenario' risk assessment has been undertaken in order to evaluate the potential radiological impact on humans and the environment of the facility, were it to be left in its current state with no remediation. The results have been used as a basis for regulatory decision making regarding remediation and decommissioning of the legacy radioactive waste facility. The aim of this study was two-fold: first to demonstrate a complete radiological risk assessment of a real site using a combination of methodologies developed by the IAEA (ISAM and BIOMASS), the second to illustrate the current state-of-the-art in respect of extracting site-specific information from site-descriptive material. We illustrate the practicality of employing geographic information systems techniques on site-specific topographic data to identify relevant biosphere dose objects, thereby allowing customisation of the generic ISAM model framework to site-specific conditions. As a result, a simple method is suggested to bound activity concentrations in well water based on an understanding of water balance in the local catchment area in which the biosphere dose object is embedded. With conservative assumptions, estimated doses from the calculation cases of the design scenario remain lower than the IAEA's dose criteria and environmental screening values. However, the results also indicate that human intrusion activities after the institutional control period could lead to radiological exposures above the IAEA's criteria for a period up to 100 000 years.

    Abstract Aims: To compare the real-world effectiveness of insulin degludec (degludec) and glargine 300 units/mL (glargine U300) in insulin-naïve adult patients with type 2 diabetes in routine US clinical practice.
    Materials and methods: CONFIRM is a non-interventional comparative effectiveness study following US patients across the continuum of care, through electronic medical records from multiple health systems and integrated delivery networks. Propensity-score matching controlled for confounding. The primary endpoint, change in HbA1c from baseline to 180 days of follow-up, was estimated using a repeated-measure of covariance analysis with subject as random effect. Change in the rate of hypoglycaemic episodes (defined using International Classification of Diseases codes 9/10) and change in proportion of patients with hypoglycaemia were estimated using negative binomial and logistic regression, respectively. Time-to-discontinuation of the initial basal insulin/initiation with another prescribed basal insulin was analysed using a Cox Proportional Hazard model.
    Results: Data concerning 4056 patients were analysed. After matching, baseline characteristics were comparable (n = 2028 in each group). After 180 days of follow-up, degludec was associated with a larger reduction in HbA1c (estimated treatment difference, -0.27%; P = 0.03), greater reductions in change in rate (rate ratio, 0.70; P < 0.05) and greater reductions in change in the likelihood of hypoglycaemia (odds ratio, 0.64; P < 0.01]) compared with glargine U300. In addition, patients treated with degludec were 27% less likely to discontinue treatment at follow-up compared with those treated with glargine U300 (hazard ratio, 0.73; P < 0.001).
    Conclusions: Significantly improved HbA1c, larger reductions in rates and likelihood of hypoglycaemia and lower risk of treatment discontinuation were demonstrated with degludec vs glargine U300.

    Abstract Escherichia coli glutaredoxin (MW 9700) catalyzes intracellular redox reactions utilizing a disulfide/dithiol enzymatic mechanism involving the active-site residues -Cys-Pro-Tyr-Cys-. It is functionally related to the thioredoxin family and is expected to share similar three-dimensional structure [Eklund, H., Cambillau, C., Sjöberg, B.-M., Holmgren, A., Jörnvall, H., Höög, J.-O., & Brändén, C.-I. (1984) EMBO J. 3, 1443-1449]. We constructed an overexpression system in which production of glutaredoxin is controlled by temperature-sensitive expression of the phage T7 promoter. In addition to glutaredoxin, a second gene product is observed; this species, which we call glutaredoxin N, is glutaredoxin extended by the sequence Met-Arg-Arg-Glu-Ile- at the N terminus. We have begun characterization of the structure and stability of the oxidized and reduced forms of glutaredoxin (grx-S2 and grx-(SH)2, respectively). Secondary structure calculated from CD data agrees with that predicted from the three-dimensional model of Eklund et al. The cooperative denaturation reactions of oxidized and reduced glutaredoxin were measured in temperature-induced and guanidine hydrochloride induced unfolding experiments. Surprisingly, oxidized and reduced glutaredoxins are very similar in stability. In heat-induced denaturation, monitored by CD, Tm is 55 and 57 degrees C for oxidized and reduced, respectively. In GuHCl denaturation, monitored by fluorescence, the midpoint denaturant concentrations are 2 M for both oxidized and reduced. It follows that the redox potentials of the disulfide bond are similar in unfolded and folded glutaredoxin. This is unexpected because in E. coli thioredoxin the oxidized form is far more stable than the reduced [Kelley, R.F., Shalongo, W., Jagannadham, M.V., & Stellwagen, E. (1987) Biochemistry 26, 1406-1411] and the redox potential of folded thioredoxin is significantly more negative than that of unfolded thioredoxin [Lin, T.-Y., & Kim, P. (1989) Biochemistry 28, 5282-5287].

    Abstract Interferometric gravitational wave detectors operate with high optical power in their arms in order to achieve high shot-noise limited strain sensitivity. A significant limitation to increasing the optical power is the phenomenon of three-mode parametric instabilities, in which the laser field in the arm cavities is scattered into higher-order optical modes by acoustic modes of the cavity mirrors. The optical modes can further drive the acoustic modes via radiation pressure, potentially producing an exponential buildup. One proposed technique to stabilize parametric instability is active damping of acoustic modes. We report here the first demonstration of damping a parametrically unstable mode using active feedback forces on the cavity mirror. A 15 538 Hz mode that grew exponentially with a time constant of 182 sec was damped using electrostatic actuation, with a resulting decay time constant of 23 sec. An average control force of 0.03 nN was required to maintain the acoustic mode at its minimum amplitude.

    Abstract This paper presents an analysis of the transient behavior of the Advanced LIGO (Laser Interferometer Gravitational-wave Observatory) suspensions used to seismically isolate the optics. We have characterized the transients in the longitudinal motion of the quadruple suspensions during Advanced LIGO's first observing run. Propagation of transients between stages is consistent with modeled transfer functions, such that transient motion originating at the top of the suspension chain is significantly reduced in amplitude at the test mass. We find that there are transients seen by the longitudinal motion monitors of quadruple suspensions, but they are not significantly correlated with transient motion above the noise floor in the gravitational wave strain data, and therefore do not present a dominant source of background noise in the searches for transient gravitational wave signals. Using the suspension transfer functions, we compared the transients in a week of gravitational wave strain data with transients from a quadruple suspension. Of the strain transients between 10 and 60 Hz, 84% are loud enough that they would have appeared above the sensor noise in the top stage quadruple suspension monitors if they had originated at that stage at the same frequencies. We find no significant temporal correlation with the suspension transients in that stage, so we can rule out suspension motion originating at the top stage as the cause of those transients. However, only 3.2% of the gravitational wave strain transients are loud enough that they would have been seen by the second stage suspension sensors, and none of them are above the sensor noise levels of the penultimate stage. Therefore, we cannot eliminate the possibility of transient noise in the detectors originating in the intermediate stages of the suspension below the sensing noise.

    Abstract We report the first observation of off-axis neutrino interactions in the MiniBooNE detector from the NuMI beam line at Fermilab. The MiniBooNE detector is located 745 m from the NuMI production target, at 110 mrad angle (6.3 degrees) with respect to the NuMI beam axis. Samples of charged-current quasielastic numicro and nue interactions are analyzed and found to be in agreement with expectation. This provides a direct verification of the expected pion and kaon contributions to the neutrino flux and validates the modeling of the NuMI off-axis beam.

    Abstract The MiniBooNE Collaboration observes unexplained electronlike events in the reconstructed neutrino energy range from 200 to 475 MeV. With 6.46x10;{20} protons on target, 544 electronlike events are observed in this energy range, compared to an expectation of 415.2+/-43.4 events, corresponding to an excess of 128.8+/-20.4+/-38.3 events. The shape of the excess in several kinematic variables is consistent with being due to either nu_{e} and nu[over ]_{e} charged-current scattering or nu_{mu} neutral-current scattering with a photon in the final state. No significant excess of events is observed in the reconstructed neutrino energy range from 475 to 1250 MeV, where 408 events are observed compared to an expectation of 385.9+/-35.7 events.

    Abstract The MiniBooNE Collaboration reports a search for nu_{micro} and nu[over]_{micro} disappearance in the Deltam;{2} region of 0.5-40 eV;{2}. These measurements are important for constraining models with extra types of neutrinos, extra dimensions, and CPT violation. Fits to the shape of the nu_{micro} and nu[over]_{micro} energy spectra reveal no evidence for disappearance at the 90% confidence level (C.L.) in either mode. The test of nu[over]_{micro} disappearance probes a region below Deltam;{2} = 40 eV;{2} never explored before.

    Abstract Using high statistics samples of charged-current numu interactions, the MiniBooNE [corrected] Collaboration reports a measurement of the single-charged-pion production to quasielastic cross section ratio on mineral oil (CH2), both with and without corrections for hadron reinteractions in the target nucleus. The result is provided as a function of neutrino energy in the range 0.4 GeV<Enu<2.4 GeV with 11% precision in the region of highest statistics. The results are consistent with previous measurements and the prediction from historical neutrino calculations.<br />
