Abstract

During the shutdown of the CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between the existing Pixel detector of the ATLAS experiment and a new, smaller radius beam pipe. The motivation for this new pixel layer, the Insertable B-Layer (IBL), was to maintain or improve the robustness and performance of the ATLAS tracking system, given the higher instantaneous and integrated luminosities realised following the shutdown. Because of the extreme radiation and collision rate environment, several new radiation-tolerant sensor and electronic technologies were utilised for this layer. This paper reports on the IBL construction and integration prior to its operation in the ATLAS detector., Comment: 90 pages in total.

Abstract

Developing appropriate monitoring strategies in long-quiescent volcanic provinces is challenging due to the rarity of recordable geochemical and geophysical signals and the lack of experienced eruptive phenomenology in living memory. This is the case in the Massif Central (France) where the last eruptive sequence formed the Pavin's Group of Volcanoes, about 7 ka ago. There, current evidence of a mantle activity reminiscence is suggested by the presence of mineral springwaters, mofettes, and soil degassing. It appears fundamental as a prerequisite to decipher the evolution of the gas phase in the magmatic system at the time of the eruptive activity to understand the meaning of current local gas emissions. In this study, we develop an innovative approach coupling CO2 densimetry and geochemistry of fluid inclusions from products erupted by the Pavin's Group of Volcanoes. 3D imagery by Raman spectroscopy revealed that carbonate forming in fluid inclusions may lead to underestimation of CO2 density in fluid inclusions by up to 50% and thus to unreliable barometric estimates. Fortunately, we found that this effect may be limited by focusing on fluid inclusions with a small diameter (

Abstract

The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L = 7.5 $\times$ 10 $^{34}$ cm $^{-2}$ s $^{-1}$ will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. A High Granularity Timing Detector (HGTD) will be installed in front of the LAr end-cap calorimeters for pile-up mitigation and luminosity measurement. The HGTD is a novel detector introduced to augment the new all-silicon Inner Tracker in the pseudo-rapidity range from 2.4 to 4.0, adding the capability to measure charged-particle trajectories in time as well as space. Two silicon-sensor double-sided layers will provide precision timing information for minimum-ionising particles with a resolution as good as 30 ps per track in order to assign each particle to the correct vertex. Readout cells have a size of 1.3 mm $\times$ 1.3 mm, leading to a highly granular detector with 3.7 million channels. Low Gain Avalanche Detectors (LGAD) technology has been chosen as it provides enough gain to reach the large signal over noise ratio needed. The requirements and overall specifications of the HGTD will be presented as well as the technical design and the project status. The on-going R\&D effort carried out to study the sensors, the readout ASIC, and the other components, supported by laboratory and test beam results, will also be presented.

Abstract

Objective: Orthopedic surgeons are the third-highest opioid prescribers in the United States. Their prescribing practices can significantly affect the quantity of unconsumed opioids available to fuel the current opioid epidemic. The aim of this study was to identify prescribing patterns and knowledge gaps among orthopedic providers for targeted future interventions and investigation. Design: An online survey describing six common orthopedic surgical scenarios was distributed electronically to determine opioid type and quantity prescribed at discharge, medication disposal instructions, and the use of prescription drug monitoring programs (PDMPs) in the prescription writing process. Setting: Tertiary care academic hospitals. Participants: Orthopedic physicians and mid-level providers practicing at Johns Hopkins Medical Institutions and University of Maryland Medical System. Of 179 providers contacted, 127 (71 percent) completed the survey. Main outcome measures: Quantity of opioid prescribed, utilization of PDMPs, and provision of opioid disposal instructions. Results: While statistically significant associations were identified between quantity of opioid prescribed and surgical procedure, for five of six scenarios 95 percent of respondents recommended prescribing >55 oxycodone 5 mg pill equivalents (PEs) at discharge. An inverse correlation between years of clinical practice and mean number of PEs prescribed was observed. Fewer than 40 percent of respondents modified prescribing when presented with clinically relevant changes in scenario (history of depression or drug abuse). Over 60 percent of respondents do not use PDMPs, and 79 percent do not provide opioid disposal instructions. Conclusions: Our findings support a need for targeted education to mitigate the role of orthopedic postoperative prescribing practices on the current opioid abuse epidemic.

Abstract

The life cycle of microorganisms is associated with dynamic metabolic transitions and complex cellular responses. In yeast, how metabolic signals control the progressive choreography of structural reorganizations observed in quiescent cells during a natural life cycle remains unclear. We have developed an integrated microfluidic device to address this question, enabling continuous single-cell tracking in a batch culture experiencing unperturbed nutrient exhaustion to unravel the coordination between metabolic and structural transitions within cells. Our technique reveals an abrupt fate divergence in the population, whereby a fraction of cells is unable to transition to respiratory metabolism and undergoes a reversible entry into a quiescence-like state leading to premature cell death. Further observations reveal that non-monotonous internal pH fluctuations in respiration-competent cells orchestrate the successive waves of protein super-assemblies formation that accompany the entry into a bona fide quiescent state. This ultimately leads to an abrupt cytosolic glass transition that occurs stochastically long after proliferation cessation. This new experimental framework provides a unique way to track single-cell fate dynamics over a long timescale in a population of cells that continuously modify their ecological niche.

Abstract

The NASA New Millennium Program's Geostationary Imaging Fourier Transform Spectrometer (GIFTS) requires highly accurate radiometric and spectral calibration in order to carry out its mission to provide water vapor, wind, temperature, and trace gas profiling from geostationary orbit. A calibration concept has been developed for the GIFTS Phase A instrument design. The in-flight calibration is performed using views of two on-board blackbody sources along with cold space. A radiometric calibration uncertainty analysis has been developed and used to show that the expected performance for GIFTS exceeds its top level requirement to measure brightness temperature to better than 1 K. For the Phase A GIFTS design, the spectral calibration is established by the highly stable diode laser used as the reference for interferogram sampling, and verified with comparisons to atmospheric calculations.

Abstract

This is the second of two Technical Design Report documents that describe the upgrade of the central tracking system for the ATLAS experiment for the operation at the High Luminosity LHC (HL-LHC) starting in the middle of 2026. At that time the LHC will have been upgraded to reach a peak instantaneous luminosity of "7.5\times 10$^{34}$ cm$^{-2}$s$^{-1}$", which corresponds to an average of about 200 inelastic proton-proton collisions per beam-crossing. The new Inner Tracker (ITk) will be operational for more than ten years, during which time ATLAS aims to accumulate a total data set of 4000 fb$^{-1}$. Many of the features of the tracker have already been presented in the first Technical Design Report that detailed the construction of the ITk Strip Tracker. That report was published in April 2017. This document focuses on the ITk Pixel Detector. A baseline design is described in detail, and the motivations for the chosen technologies are illustrated. In some cases, alternative solutions are also illustrated. In this case, we indicate the advantage in pursuing the other designs, and describe the time line for a decision. The design, construction and expected performance are set out in detail. When considering performance we pay particular attention to those parameters that are determined by the performance of the Pixel Detector. We describe in detail the design and construction of the Pixel Detector, including the results of measurements of prototype modules and associated support structures and we explain the status of the plans for their mass production. We present details of the decommissioning of the existing tracking detector and the replacement of the inner layers of the ITk Pixel Detector part way through the lifetime of the High Luminosity LHC. Finally, we describe the costing and schedule, including major milestones, to construct the detector.

Abstract

The last half year was spent in preparing Version 1 software for delivery, and culminated in transfer of the Level 2 cloud mask production software to the SDST in April. A simulated MODIS test data set with good radiometric integrity was produced using MAS data for a clear ocean scene. ER-2 flight support and MAS data processing were provided by CIMSS personnel during the Apr-May 96 SUCCESS field campaign in Salina, Kansas. Improvements have been made in the absolute calibration of the MAS, including better characterization of the spectral response for all 50 channels. Plans were laid out for validating and testing the MODIS calibration techniques; these plans were further refined during a UW calibration meeting with MCST.

Abstract

© 2017 Elsevier B.V. Laser induced breakdown spectroscopy (LIBS), as performed by the ChemCam instrument, provides a new technique to measure hydrogen at the surface of Mars. Using a laboratory replica of the LIBS instrument onboard the Curiosity rover, different types of hydrated samples (basalts, calcium and magnesium sulfates, opals and apatites) covering a range of targets observed on Mars have been characterized and analyzed. A number of factors related to laser parameters, atmospheric conditions and differences in targets properties can affect the standoff LIBS signal, and in particular the hydrogen emission peak. Dedicated laboratory tests were run to identify a normalization of the hydrogen signal which could best compensate for these effects and enable the application of the laboratory calibration to Mars data. We check that the hydrogen signal increases linearly with water content; and normalization of the hydrogen emission peak using to oxygen and carbon emission peaks (related to the breakdown of atmospheric carbon dioxide) constitutes a robust approach. Moreover, the calibration curve obtained is relatively independent of the samples types.

Abstract

In order to characterize the effect of ascent rate on the kinetics of bubble nucleation in a rhyolitic magma, we performed three series of experiments decompressed at 1000, 167, or 27.8 kPa/s. The experiments were carried out in an externally heated pressure vessel at 800°C; the starting material was a crystal-free and bubble-free rhyolitic glass containing 7.0 wt.% H2O. In the three decompression series, homogeneous bubble nucleation began at 90 MPa, that is, ≡ 150 MPa below the water saturation pressure of the silicate liquid, 240 MPa. After a short nucleation event, the nucleation rate dropped and the bubble number density N reached a stationary value that was strongly sensitive to decompression rate: 6.8 mm 3 at 27.8 kPa/s, 470 mm 3 at 167 kPa/s, and 5800 mm 3 at 1000 kPa/s. This behaviour was dictated by a competition between nucleation and diffusive bubble growth, which depleted in water the surrounding liquid and so reduced the degree of volatile supersaturation. With increasing N, the length scale of diffusion of water molecules to growing bubbles decreased: nucleation stopped when N attained a critical value, at which the degree of volatile supersaturation in the liquid was everywhere below the value required for nucleation and no longer increased with decreasing pressure. The strong correlation between bubble number density and decompression rate has fundamental volcanological implications. If we extrapolate the experimental data to the typical ascent rates of silicic magmas, we obtain bubble number densities that are orders of magnitude smaller than those measured in most natural pumices. We propose that the large values of N in silicic pumices may be due to two successive nucleation events: (1) a first event, which occurs relatively deep in the volcanic conduit and which yields a moderate number of bubbles; and (2) a second nucleation event, yielding a very large number of small bubbles, and presumably related to the dramatic increase of decompression rate that precedes fragmentation.

Abstract

International audience; A tunable monochromatic x-ray source covering the 1-20 keV energy range is described. The initial x-ray beam is obtained from a dedicated windowless x-ray tube. The energy selection is performed through a cylindrically bent crystal, used either in the reflection (Johann geometry) or in the transmission (Cauchois geometry) mode, by rotating the crystal holder by a 90° angle. Contrary to conventional geometries where the x-ray tube is fixed, here the direction of the exit beam impinging the x-ray detector is fixed. This setup is shown to be useful for various studies: high-resolution spectrometry, characterization of the response function and the efficiency of detectors and optical components, determination of transmission characteristics of different materials. Observations of the Lα line and Kα doublet from a copper anode are presented, that demonstrate the performance of this new setup.; Une source de rayons X monochromatique accordable dans le domaine de (1 à 20) keV est décrite. Le rayonnement est produit par un tube à rayons X sans fenêtre, fonctionnant entre (1 et 50) kV. La sélection en énergie est réalisée à l'aide d'un spectromètre à cristal courbé cylindriquement utilisable, soit dans le mode réflexion (géométrie Johann), soit dans le mode transmission (géométrie Cauchois). Le passage de l'une à l'autre de ces géométries se fait par simple rotation du cristal. La direction du faisceau monochromatique est fixe. Cet appareillage est utilisable à la fois comme spectromètre à haute résolution et comme monochromateur. Il a été spécialement conçu pour des études de métrologie, telles que la caractérisation de détecteurs et d'optiques du domaine X.

43. Formation of U-depleted rhyolite from a basanite at El Hierro, Canary Islands

Abstract

Phonolite and trachyte are the felsic magmas of the alkaline magma suites, which characterize the Canary Islands. The October 2011 submarine eruption off El Hierro, the westernmost island, nevertheless, produced a small volume of rhyolitic magma. The rhyolite occurred as highly vesicular, white coloured pumices enveloped in and mingled with darker coloured basanitic pumice. The basanitic pumice is relatively crystal poor with a few euhedral olivines (mostly Fo77-79), clinopyroxenes and Fe-rich spinels, whereas very rare olivine of same composition is found together with equally rare Fe-sulphide and FeTi-rich oxides in the rhyolite. The Fe-Mg exchange equilibrium in the oxides permits to calculate an equilibrium temperature of 970-890 °C for the rhyolite, in agreement with quartz-melt equilibrium at ca. 930 °C. A striking mineralogical feature of the rhyolite is the presence of rounded to contorted grains of milky quartz, which are xenocrysts incorporated and partly dissolved into the magma. Analyses of residual volatile concentrations in the glasses show that the rhyolite melt was highly degassed, whereas the basanitic glass still has important halogen concentrations. Trace element patterns of the mafic glasses and their elevated incompatible element concentrations are typical of the western Canary Island basanites. In contrast, the trace element composition of the rhyolite shows surprisingly low concentrations for all elements except the most incompatible ones (e. g. Rb, Ba, K and Th). All other measured LILE, HFSE and REE have significantly lower concentration than the basanitic counterpart that can be explained by fractionation of accessory phases (1 % apatite, 1 % sphene and 0.1 % zircon). Surprisingly, low U concentration is presumably related to elevated oxygen fugacity in the rhyolite, causing U to be in a hexavalent state, and fluxing of F-rich gas leading to volatilization of UF6, known to emanate at low temperature. The results suggest that a gas-rich basa

44. Continent Formation in the Archean and Chemical Evolution of the Cratonic Lithosphere: Melt-Rock Reaction Experiments at 3-4 GPa and Petrogenesis of Archean Mg-Diorites (Sanukitoids)

Abstract

To better understand the genetic relationship between granitoid rocks of the Archean cratons and the underlying 'keel' of subcratonic lithospheric mantle (SCLM), we have conducted two types of experiments in a multi-anvil apparatus at 3-4 GPa: (1) peridotite assimilation experiments, in which natural, hydrousTTG (trondhjemite tonalite-granodiorite) melts are reacted with mantle peridotite at relatively high melt-rock ratios; (2) liquidus saturation experiments on hydrous Mg-rich diorite (sanukitoid) melts. Our results demonstrate that liquids similar to typically late- to post-tectonic sanukitoid intrusions can form by hybridization of initial TTG melts by assimilation of olivine-bearing peridotite, and that these primitive granitoid melts are in equilibrium with reaction residues consisting of olivine-free garnet websterite or garnet pyroxenite. The experimental melts retain the distinctive trace element signature of TTGs, overprinted by a 'primitive' mantle signature (i.e. high Mg-number, elevated Cr and Ni abundances), whereas the various phases of the crystalline residues acquire trace element signatures reflecting equilibration with Mg-rich granitoid melts. At low melt: rock ratios, metasomatism by TTG melts may be responsible for the silica enrichment and high modal orthopyroxene content of some cratonic peridotites and cryptic trace element overprints in garnet, clinopyroxene, and orthopyroxene. Our results demonstrate that the lithospheric keel of Archean cratons represents the product of reaction betweenTTG melts and previously depleted mantle peridotite at relatively low melt:rock ratios, as evidenced by the trace element signature in garnet pyroxenite and orthopyroxene-enriched garnet peridotite xenoliths, whereas Late Archean sanukitoids represent the products of these same reactions at relatively high melt:rock ratios.

Abstract

A calibrated Fourier transform spectrometer, known as the High-Resolution Interferometer Sounder (HIS), has been flown on the NASA U-2 research aircraft to measure the infrared emission spectrum of the earth. The primary use - atmospheric temperature and humidity sounding - requires high radiometric precision and accuracy (of the order of 0.1 and 1 C, respectively). To meet these requirements, the HIS instruments, the HIS instrument performs inflight radiometric calibration, using observations of hot and cold blackbody reference sources as the basis for two-point calibrations at each wavenumber. Initially, laboratory tests revealed a calibration problem with brightness temperature errors as large as 15 C between 600 and 900/cm. The symptom of the problem, which occurred in one of the three spectral bands of HIS, was a source-dependent phase response. Minor changes to the calibration equations completely eliminated the anomalous errors. The new analysis properly accounts for the situation in which the phase response for radiance from the instrument itself differs from that for radiance from an external source. The mechanism responsible for the dual phase response of the HIS instrument is identified as emission from the interferometer beam splitter.

Abstract

The global distribution of the water vapor has been mapped at low resolution throughout the period from the northern summer solstice to the following equinox. During this seasonal period the water vapor underwent a gradual redistribution, the latitude of maximum column abundance moving from the northern polar area to the equatorial latitudes. The total global vapor content remained approximately constant at the equivalent of about 1.3 cu km of ice. The various data obtained indicate that the residual polar caps are composed of water ice.

50. Behavior of volatiles in Mars' polar areas - A model incorporating new experimental data

Abstract

A model has been developed to explain the north polar water vapor results obtained by the Viking orbiter Mars atmospheric water detector; it has also been used to compute the thickness of seasonally deposited CO2 frost, the variation of the total atmospheric pressure, and wind velocities due to mass motions associated with CO2 condensation. A north polar water ice thickness in excess of 1 m and an ice albedo a of 0.34(+0.06,-0.03) are inferred from a comparison of the model and experimental data. The model results confirm an earlier conclusion that the atmosphere over the ice is saturated. It is suggested that concentration of the atmospheric inert gases in the polar region, combined with local topography and arctic circulation patterns, could be responsible for the south remnant cap not being at the south pole
