Abstract

Multi-drug resistant (MDR) Acinetobacter baumannii (Ab) and Acinetobacter spp. present monumental global health challenges. These organisms represent model Gram-negative pathogens with known antibiotic resistance and biofilm-forming properties. Herein, a novel, nontoxic biocide, AB569, consisting of acidified nitrite (A-NO2-) and ethylenediaminetetraacetic acid (EDTA), demonstrated bactericidal activity against all Ab and Acinetobacter spp. strains, respectively. Average fractional inhibitory concentrations (FICs) of 0.25 mM EDTA plus 4 mM A-NO2- were observed across several clinical reference and multiple combat wound isolates from the Iraq/Afghanistan wars. Importantly, toxicity testing on human dermal fibroblasts (HDFa) revealed an upper toxicity limit of 3 mM EDTA plus 64 mM A-NO2-, and thus are in the therapeutic range for effective Ab and Acinetobacter spp. treatment. Following treatment of Ab strain ATCC 19606 with AB569, quantitative PCR analysis of selected genes products to be responsive to AB569 revealed up-regulation of iron regulated genes involved in siderophore production, siderophore biosynthesis non-ribosomal peptide synthetase module (SBNRPSM), and siderophore biosynthesis protein monooxygenase (SBPM) when compared to untreated organisms. Taken together, treating Ab infections with AB569 at inhibitory concentrations reveals the potential clinical application of preventing Ab from gaining an early growth advantage during infection followed by extensive bactericidal activity upon subsequent exposures.

Abstract

Burnout is reaching epidemic levels among health care providers. It negatively impacts individual providers, the care team, facility, and patients. Increased employee turnover, job dissatisfaction, and conflict are found whenever staff becomes burned out. Patient outcomes and satisfaction are negatively impacted. Although burnout is increasing in health care, much can be done to change the level of burnout and improve employee satisfaction. Individuals can learn the factors that lead to burnout and specific actions that can help prevent and recover from burnout. This information can be used to transform health care and decrease burnout and its effects.

Abstract

Today's health care environment emphasizes patient outcomes, although financial incentives and penalties have placed a high priority on elimination of health care-associated infections (HAIs). The use of standardized care bundles is evidence-based; however, implementation of these bundles has not proven effective in eliminating HAIs. Actively learning from HAI events through the use of apparent and systemic cause analysis identifies new barriers to success and opportunities for improvement in further reducing HAIs. The effective use of apparent and systemic cause analysis requires a standardized review and is followed with the implementation of appropriate steps to remove newly identified barriers.

Abstract

Antibiotic-resistant superbug bacteria represent a global health problem with no imminent solutions. Here we demonstrate that the combination (termed AB569) of acidified nitrite (A-NO 2 − ) and Na 2 -EDTA (disodium ethylenediaminetetraacetic acid) inhibited all Gram-negative and Gram-positive bacteria tested. AB569 was also efficacious at killing the model organism Pseudomonas aeruginosa in biofilms and in a murine chronic lung infection model. AB569 was not toxic to human cell lines at bactericidal concentrations using a basic viability assay. RNA-Seq analyses upon treatment of P. aeruginosa with AB569 revealed a catastrophic loss of the ability to support core pathways encompassing DNA, RNA, protein, ATP biosynthesis, and iron metabolism. Electrochemical analyses elucidated that AB569 produced more stable SNO proteins, potentially explaining one mechanism of bacterial killing. Our data implicate that AB569 is a safe and effective means to kill pathogenic bacteria, suggesting that simple strategies could be applied with highly advantageous therapeutic/toxicity index ratios to pathogens associated with a myriad of periepithelial infections and related disease scenarios.

Abstract

Traditional timber connections with wood pegs are encountered in the renovation and rehabilitation of historic wood structures and in the construction of new structures where rustic appearance and traditional methods are desired. This study examined four types of traditional connections: mortise and tenon, mortise and tenon with a shoulder, mortise and tenon with a shoulder and a knee brace, and fork and tongue. A total of 60 specimens, primarily white oak and Douglas fir, were tested. About a quarter of the specimens were assembled and allowed to season under simulated in-service load. All specimens were tested under simulated gravity load up to failure or to about five times typical design load. Some knee-braced specimens were retested to simulate lateral loads. Test results showed that joint behavior is primarily linear. A tightly fitting joint carries load with less peg damage than a loose joint allows. A mortise and tenon with a shoulder performs better than a mortise and tenon or a fork and tongue. At typical occupancy sustained live plus dead load levels, the effects of warping and checking caused by drying shrinkage overshadow any damage caused by the sustained load. Analysis of structures employing these connections requires that the behavior of the wood-pegged joints be included in a reasonable manner. In frames without knee braces, the joints can be modeled as pinned connections. In frames with knee braces, the post-to-beam and knee-brace connections can be modeled as pinned, although the reduction in effective axial stiffness of the knee brace caused by the wood pegs must be included. The effects of shear deformations should be incorporated into the analysis.

Abstract

Patient- and family-centered care is endorsed by leading health care organizations. To incorporate the family in interdisciplinary rounds in the pediatric intensive care unit, it is necessary to prepare the family to be an integral member of the child's health care team. When the family is part of the health care team, interdisciplinary rounds ensure that the family understands the process of interdisciplinary rounds and that it is an integral part of the discussion. An evidence-based protocol to provide understanding and support to families related to interdisciplinary rounds has significant impact on satisfaction, trust, and patient outcomes.

Abstract

We present the results of a LIGO search for short-duration gravitational waves (GWs) associated with the 2006 March 29 SGR 1900+14 storm. A new search method is used, "stacking'' the GW data around the times of individual soft-gamma bursts in the storm to enhance sensitivity for models in which multiple bursts are accompanied by GW emission. We assume that variation in the time difference between burst electromagnetic emission and potential burst GW emission is small relative to the GW signal duration, and we time-align GW excess power time-frequency tilings containing individual burst triggers to their corresponding electromagnetic emissions. We use two GW emission models in our search: a fluence-weighted model and a flat (unweighted) model for the most electromagnetically energetic bursts. We find no evidence of GWs associated with either model. Model-dependent GW strain, isotropic GW emission energy E_GW, and \gamma = E_GW / E_EM upper limits are estimated using a variety of assumed waveforms. The stacking method allows us to set the most stringent model-dependent limits on transient GW strain published to date. We find E_GW upper limit estimates (at a nominal distance of 10 kpc) of between 2x10^45 erg and 6x10^50 erg depending on waveform type. These limits are an order of magnitude lower than upper limits published previously for this storm and overlap with the range of electromagnetic energies emitted in SGR giant flares., Comment: 7 pages, 3 figures

Abstract

The fourth science run of the LIGO and GEO 600 gravitational-wave detectors, carried out in early 2005, collected data with significantly lower noise than previous science runs. We report on a search for short-duration gravitational-wave bursts with arbitrary waveform in the 64-1600 Hz frequency range appearing in all three LIGO interferometers. Signal consistency tests, data quality cuts, and auxiliary-channel vetoes are applied to reduce the rate of spurious triggers. No gravitational-wave signals are detected in 15.5 days of live observation time; we set a frequentist upper limit of 0.15 per day (at 90% confidence level) on the rate of bursts with large enough amplitudes to be detected reliably. The amplitude sensitivity of the search, characterized using Monte Carlo simulations, is several times better than that of previous searches. We also provide rough estimates of the distances at which representative supernova and binary black hole merger signals could be detected with 50% efficiency by this analysis., Comment: Corrected amplitude sensitivities (7% change on average); 30 pages, submitted to Classical and Quantum Gravity

Abstract

Computerized technologies now offer unprecedented opportunities to provide real-time visual feedback to facilitate children’s speech–language development. We employed a mixed-method design to examine the effectiveness of two speech–language interventions aimed at facilitating children’s multisyllabic productions: one incorporated a novel computerized feedback system, VocSyl, while the other used a traditional noncomputerized pacing board. Eighteen children with a variety of diagnoses, all of whom were at the single word stage of development, enrolled in either one of the two explicit speech–language interventions (VocSyl or Pacing Board) or an active control group. Convergent findings between and within groups supported the effectiveness of the VocSyl condition. For the children with a clinical diagnosis of autism in particular, visual inspection of individual data on treatment versus control targets indicated positive treatment effects for both of the two children enrolled in the VocSyl condition and one of the two children enrolled in the Pacing Board condition. Although the study does not permit definitive conclusions about the effectiveness of any particular treatment tool or strategy in isolation, it offers preliminary support for the integration of real-time computerized feedback within speech–language intervention.

Abstract

The objectives of this paper are to present experimental data and analytical models to assist in the analysis and design of pegged joints in traditional timber frames. Seventy-two simplified mortise and tenon joints were loaded to failure under compression-induced double shear. Load, deformation, and time were recorded. All joints utilized 25.4-mm-diameter red oak pegs, typical of those used in modern timber-frame construction in North America. Half of the specimens were made with eastern white pine lumber, with the remaining specimens made of sugar maple. All specimens had 50.8 mm center pieces simulating a typical tenon. Side pieces were evenly divided into 25.4 mm and 50.8 mm thicknesses. Half of the specimens were arranged such that the center piece was loaded parallel to the grain and the side pieces perpendicular. Grain orientation was reversed for the remaining specimens. Joint stiffness was estimated by a regression analysis of the linear portion of the load-slip curves. A model for joint stiffnes...

Abstract

Traditional timber connections with wood pegs are encountered in the renovation and rehabilitation of historic wood structures and in the construction of new structures where rustic appearance and traditional methods are desired. This study examined four types of traditional connections: mortise and tenon, mortise and tenon with a shoulder, mortise and tenon with a shoulder and a knee brace, and fork and tongue. A total of 60 specimens, primarily white oak and Douglas fir, were tested. About a quarter of the specimens were assembled and allowed to season under simulated in-service load. All specimens were tested under simulated gravity load up to failure or to about five times typical design load. Some knee-braced specimens were retested to simulate lateral loads. Test results showed that joint behavior is primarily linear. A tightly fitting joint carries load with less peg damage than a loose joint allows. A mortise and tenon with a shoulder performs better than a mortise and tenon or a fork and tongue. ...

Abstract

OBJECTIVES. This study analyzed the prevalence and determinants of the quality of condom use after a woman's first visit to a family planning clinic. METHODS. This report presents data from 360 female family planning clients who reported using condoms as their primary method of contraception for at least 1 sexually active month during the study's follow-up period after their first clinic visit. RESULTS. Only 1% always engaged in all five use behaviors studied: using a condom for each sexual intercourse, putting the condom on before first entry, withdrawal after intercourse while there is still an erection, holding on to the condom's rim during withdrawal, and using foam. Multiple linear regression indicated that more effective condom use was reported by women who had not had an induced abortion, were not using condoms just because they were starting oral contraceptive pill regimens, had more knowledge about birth control in general, had received a nursing intervention, and had more communication with their partner. CONCLUSIONS. Increasing attention needs to be devoted to understanding determinants of the specific actions that differentiate between more and less effective contraceptive use.

Abstract

We report on a matched-filter search for gravitational wave bursts from cosmic string cusps using LIGO data from the fourth science run (S4) which took place in February and March 2005. No gravitational waves were detected in 14.9 days of data from times when all three LIGO detectors were operating. We interpret the result in terms of a frequentist upper limit on the rate of gravitational wave bursts and use the limits on the rate to constrain the parameter space (string tension, reconnection probability, and loop sizes) of cosmic string models., Comment: 11 pages, 3 figures.

Abstract

We report on a search for gravitational waves from coalescing compact binaries, of total mass between 2 and 35M(circle dot), using LIGO observations between November 14, 2006 and May 18, 2007. No gravitational-wave signals were detected. We report upper limits on the rate of compact binary coalescence as a function of total mass. The LIGO cumulative 90%-confidence rate upper limits of the binary coalescence of neutron stars, black holes and black hole-neutron star systems are 1.4x10(-2), 7.3x10(-4) and 3.6x10(-3) yr(-1) L-10(-1), respectively, where L-10 is 10(10) times the blue solar luminosity.

Abstract

This paper reports on an all-sky search for periodic gravitational waves from sources such as deformed isolated rapidly-spinning neutron stars. The analysis uses 840 hours of data from 66 days of the fifth LIGO science run (S5). The data was searched for quasi-monochromatic waves with frequencies f in the range from 50 Hz to 1500 Hz, with a linear frequency drift \dot{f} (measured at the solar system barycenter) in the range -f/\tau < \dot{f} < 0.1 f/\tau, for a minimum spin-down age \tau of 1000 years for signals below 400 Hz and 8000 years above 400 Hz. The main computational work of the search was distributed over approximately 100000 computers volunteered by the general public. This large computing power allowed the use of a relatively long coherent integration time of 30 hours while searching a large parameter space. This search extends Einstein@Home's previous search in LIGO S4 data to about three times better sensitivity. No statistically significant signals were found. In the 125 Hz to 225 Hz band, more than 90% of sources with dimensionless gravitational-wave strain tensor amplitude greater than 3e-24 would have been detected., Comment: 14 pages, 7 figures

Abstract

According to general relativity a perturbed black hole will settle to a stationary configuration by the emission of gravitational radiation. Such a perturbation will occur, for example, in the coalescence of a black hole binary, following their inspiral and subsequent merger. At late times the waveform is a superposition of quasi-normal modes, which we refer to as the ringdown. The dominant mode is expected to be the fundamental mode, l=m=2. Since this is a well-known waveform, matched filtering can be implemented to search for this signal using LIGO data. We present a search for gravitational waves from black hole ringdowns in the fourth LIGO science run S4, during which LIGO was sensitive to the dominant mode of perturbed black holes with masses in the range of 10 Msun to 500 Msun, the regime of intermediate-mass black holes, to distances up to 300 Mpc. We present a search for gravitational waves from black hole ringdowns using data from S4. No gravitational wave candidates were found; we place a 90%-confidence upper limit on the rate of ringdowns from black holes with mass between 85 Msun and 390 Msun in the local universe, assuming a uniform distribution of sources, of 3.2 x 10^{-5} yr^{-1} Mpc^{-3} = 1.6 x 10^{-3}yr^{-1} L_{10}^{-1}, where L_{10} is 10^{10} times the solar blue-light luminosity., 8 pages, 6 figures

Abstract

We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1100Hz and with the frequency's time derivative in the range -5×10-9-0Hzs-1. Data from the first eight months of the fifth LIGO science run (S5) have been used in this search, which is based on a semicoherent method (PowerFlux) of summing strain power. Observing no evidence of periodic gravitational radiation, we report 95% confidence-level upper limits on radiation emitted by any unknown isolated rotating neutron stars within the search range. Strain limits below 10-24 are obtained over a 200-Hz band, and the sensitivity improvement over previous searches increases the spatial volume sampled by an average factor of about 100 over the entire search band. For a neutron star with nominal equatorial ellipticity of 10-6, the search is sensitive to distances as great as 500pc. © 2009 The American Physical Society.

Abstract

A search for periodic gravitational waves, from sources such as isolated rapidly-spinning neutron stars, was carried out using 510 hours of data from the fourth LIGO science run (S4). The search was for quasi-monochromatic waves in the frequency range from 50 Hz to 1500 Hz, with a linear frequency drift f-dot (measured at the solar system barycenter) in the range -f/tau < f-dot < 0.1 f/tau, where the minimum spin-down age tau was 1000 years for signals below 300 Hz and 10000 years above 300 Hz. The main computational work of the search was distributed over approximately 100000 computers volunteered by the general public. This large computing power allowed the use of a relatively long coherent integration time of 30 hours, despite the large parameter space searched. No statistically significant signals were found. The sensitivity of the search is estimated, along with the fraction of parameter space that was vetoed because of contamination by instrumental artifacts. In the 100 Hz to 200 Hz band, more than 90% of sources with dimensionless gravitational wave strain amplitude greater than 1e-23 would have been detected., 29 pages, 19 figures

Abstract

We present the results obtained from an all-sky search for gravitational-wave (GW) bursts in the 64-2000 Hz frequency range in data collected by the LIGO detectors during the first year (November 2005 - November 2006) of their fifth science run. The total analyzed livetime was 268.6 days. Multiple hierarchical data analysis methods were invoked in this search. The overall sensitivity expressed in terms of the root-sum-square (rss) strain amplitude h_{rss} for gravitational-wave bursts with various morphologies was in the range of 6 times 10^{-22} Hz^{-1/2} to a few times 10^{-21} Hz^{-1/2}. No GW signals were observed and a frequentist upper limit of 3.6 events per year on the rate of strong GW bursts was placed at the 90% confidence level. As in our previous searches, we also combined this rate limit with the detection efficiency for selected waveform morphologies to obtain event rate versus strength exclusion curves. In sensitivity, these exclusion curves are the most stringent to date., Comment: v3: various figure and text edits; submitted to PRD; 26 pages

Abstract

An error has been found in the computation of the C parameter defined in Eq. (44), which led to its overestimation by a factor 2(1/4). The correct values for C are 9.2, 9.7, and 9.3 for the multi-interferometer, H1 and L1 analyses, respectively. None of the upper limits presented in the article were affected.

Abstract

We present an all-sky search for gravitational waves in the frequency range 1 to 6 kHz during the first calendar year of LIGO's fifth science run. This is the first untriggered LIGO burst analysis to be conducted above 3 kHz. We discuss the unique properties of interferometric data in this regime. 161.3 days of triple-coincident data were analyzed. No gravitational events above threshold were observed and a frequentist upper limit of 5.4 events per year on the rate of strong gravitational wave bursts was placed at a 90% confidence level. Implications for specific theoretical models of gravitational wave emission are also discussed., Comment: 13 pages, accepted for publication in Physical Review D

Abstract

We have searched for gravitational waves from coalescing low mass compact binary systems with a total mass between 2 and 35 Msun and a minimum component mass of 1 Msun using data from the first year of the fifth science run (S5) of the three LIGO detectors, operating at design sensitivity. Depending on mass, we are sensitive to coalescences as far as 150 Mpc from the Earth. No gravitational wave signals were observed above the expected background. Assuming a compact binary objects population with a Gaussian mass distribution representing binary neutron star systems, black hole-neutron star binary systems, and binary black hole systems, we calculate the 90%-confidence upper limit on the rate of coalescences to be 3.9 \times 10^{-2} yr^{-1} L_{10}^{-1}, 1.1 \times 10^{-2} yr^{-1} L_{10}^{-1}, and 2.5 \times 10^{-3} yr^{-1} L_{10}^{-1} respectively, where $L_{10}$ is $10^{10}$ times the blue solar luminosity. We also set improved upper limits on the rate of compact binary coalescences per unit blue-light luminosity, as a function of mass., Comment: 15 pages, 5 figures, 2 tables; changes associated with referee comments, inclusion of recent LIGO calibration data, fixing small error in upper limit calculation

Abstract

A two‐year aging study was presented for four sealants: a low‐modulus silicone, a medium‐modulus silicone, a one‐part polyurethane, and a two‐part polyurethane. A specimen, with red granite substrates, is used. The four aging exposures are: ordinary room conditions; outdoors in Houghton, Michigan; outdoors near Hilo, Hawaii; and aging in a Q‐Panel (QUV) weathering unit. Following an initial six‐week cure, room‐ and outdoor‐aged specimens are tested at zero‐, six‐, 12‐, and 24‐month intervals. The QUV‐aged specimens are tested after 0, 500, 1,000, and 5,000 hours. In the postaging tests, specimens are given 20 displacement cycles at the sealant's rated movement capacity and elongated to failure. Reported data include nominal stresses at 25%, 50%, and 100% elongation, the ultimate tensile strength, and the corresponding elongation. Additionally, observations are given for surface cracking and dirt pickup. Adhesion to the substrates is good for all four sealants. Results of a pilot study combining QUV exposu...

Abstract

We present the results of a LIGO search for short-duration gravitational waves (GWs) associated with Soft Gamma Repeater (SGR) bursts. This is the first search sensitive to neutron star f-modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from SGR 1806-20 and 190 lesser events from SGR 1806-20 and SGR 1900+14 which occurred during the first year of LIGO's fifth science run. GW strain upper limits and model-dependent GW emission energy upper limits are estimated for individual bursts using a variety of simulated waveforms. The unprecedented sensitivity of the detectors allows us to set the most stringent limits on transient GW amplitudes published to date. We find upper limit estimates on the model-dependent isotropic GW emission energies (at a nominal distance of 10 kpc) between 3x10^45 and 9x10^52 erg depending on waveform type, detector antenna factors and noise characteristics at the time of the burst. These upper limits are within the theoretically predicted range of some SGR models., Comment: 6 pages, 1 Postscript figure

Abstract

We report on a search for gravitational waves from the coalescence of compact binaries during the third and fourth LIGO science runs. The search focused on gravitational waves generated during the inspiral phase of the binary evolution. In our analysis, we considered three categories of compact binary systems, ordered by mass: (i) primordial black hole binaries with masses in the range 0.35 M(sun) < m1, m2 < 1.0 M(sun), (ii) binary neutron stars with masses in the range 1.0 M(sun) < m1, m2 < 3.0 M(sun), and (iii) binary black holes with masses in the range 3.0 M(sun)< m1, m2 < m_(max) with the additional constraint m1+ m2 < m_(max), where m_(max) was set to 40.0 M(sun) and 80.0 M(sun) in the third and fourth science runs, respectively. Although the detectors could probe to distances as far as tens of Mpc, no gravitational-wave signals were identified in the 1364 hours of data we analyzed. Assuming a binary population with a Gaussian distribution around 0.75-0.75 M(sun), 1.4-1.4 M(sun), and 5.0-5.0 M(sun), we derived 90%-confidence upper limit rates of 4.9 yr^(-1) L10^(-1) for primordial black hole binaries, 1.2 yr^(-1) L10^(-1) for binary neutron stars, and 0.5 yr^(-1) L10^(-1) for stellar mass binary black holes, where L10 is 10^(10) times the blue light luminosity of the Sun., 12 pages, 11 figures

Abstract

We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1000 Hz and with the frequency's time derivative in the range -1.0E-8 Hz/s to zero. Data from the fourth LIGO science run (S4) have been used in this search. Three different semi-coherent methods of transforming and summing strain power from Short Fourier Transforms (SFTs) of the calibrated data have been used. The first, known as "StackSlide", averages normalized power from each SFT. A "weighted Hough" scheme is also developed and used, and which also allows for a multi-interferometer search. The third method, known as "PowerFlux", is a variant of the StackSlide method in which the power is weighted before summing. In both the weighted Hough and PowerFlux methods, the weights are chosen according to the noise and detector antenna-pattern to maximize the signal-to-noise ratio. The respective advantages and disadvantages of these methods are discussed. Observing no evidence of periodic gravitational radiation, we report upper limits; we interpret these as limits on this radiation from isolated rotating neutron stars. The best population-based upper limit with 95% confidence on the gravitational-wave strain amplitude, found for simulated sources distributed isotropically across the sky and with isotropically distributed spin-axes, is 4.28E-24 (near 140 Hz). Strict upper limits are also obtained for small patches on the sky for best-case and worst-case inclinations of the spin axes., Comment: 39 pages, 41 figures An error was found in the computation of the C parameter defined in equation 44 which led to its overestimate by 2^(1/4). The correct values for the multi-interferometer, H1 and L1 analyses are 9.2, 9.7, and 9.3, respectively. Figure 32 has been updated accordingly. None of the upper limits presented in the paper were affected

Abstract

We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. The first search is targeted at isolated, previously unknown neutron stars and covers the entire sky in the frequency band 160-728.8 Hz. The second search targets the accreting neutron star in the low-mass X-ray binary Scorpius X-1, covers the frequency bands 464-484 Hz and 604-624 Hz, and two binary orbit parameters. Both searches look for coincidences between the Livingston and Hanford 4-km interferometers. For isolated neutron stars our 95% confidence upper limits on the gravitational wave strain amplitude range from 6.6E-23 to 1E-21 across the frequency band; For Scorpius X-1 they range from 1.7E-22 to 1.3E-21 across the two 20-Hz frequency bands. The upper limits presented in this paper are the first broad-band wide parameter space upper limits on periodic gravitational waves using coherent search techniques. The methods developed here lay the foundations for upcoming hierarchical searches of more sensitive data which may detect astrophysical signals., 35 pages, 30 figures

Abstract

We have searched for gravitational waves (GWs) associated with the SGR 1806−20 hyperflare of 27 December 2004. This event, originating from a Galactic neutron star, displayed exceptional energetics. Recent investigations of the x-ray light curve’s pulsating tail revealed the presence of quasiperiodic oscillations (QPOs) in the 30–2000 Hz frequency range, most of which coincides with the bandwidth of the LIGO detectors. These QPOs, with well-characterized frequencies, can plausibly be attributed to seismic modes of the neutron star which could emit GWs. Our search targeted potential quasimonochromatic GWs lasting for tens of seconds and emitted at the QPO frequencies. We have observed no candidate signals above a predetermined threshold, and our lowest upper limit was set by the 92.5 Hz QPO observed in the interval from 150 s to 260 s after the start of the flare. This bound corresponds to a (90% confidence) root-sum-squared amplitude h^(90%)_(rss-det) =4.5×10^(−22) strain Hz^(−1/2) on the GW waveform strength in the detectable polarization state reaching our Hanford (WA) 4 km detector. We illustrate the astrophysical significance of the result via an estimated characteristic energy in GW emission that we would expect to be able to detect. The above result corresponds to 7.7×10^(46) erg (=4.3×10^(−8) M_⊙c^2), which is of the same order as the total (isotropic) energy emitted in the electromagnetic spectrum. This result provides a means to probe the energy reservoir of the source with the best upper limit on the GW waveform strength published and represents the first broadband asteroseismology measurement using a GW detector.

Abstract

We searched for an anisotropic background of gravitational waves using data from the LIGO S4 science run and a method that is optimized for point sources. This is appropriate if, for example, the gravitational wave background is dominated by a small number of distinct astrophysical sources. No signal was seen. Upper limit maps were produced assuming two different power laws for the source strain power spectrum. For an f^-3 power law and using the 50 Hz to 1.8 kHz band the upper limits on the source strain power spectrum vary between 1.2e-48 Hz^-1 (100 Hz/f)^3 and 1.2e-47 Hz^-1 (100 Hz /f)^3, depending on the position in the sky. Similarly, in the case of constant strain power spectrum, the upper limits vary between 8.5e-49 Hz^-1 and 6.1e-48 Hz^-1. As a side product a limit on an isotropic background of gravitational waves was also obtained. All limits are at the 90% confidence level. Finally, as an application, we focused on the direction of Sco-X1, the closest low-mass X-ray binary. We compare the upper limit on strain amplitude obtained by this method to expectations based on the X-ray luminosity of Sco-X1., Comment: 11 pages, 9 figures, 2 tables

Abstract

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has performed the fourth science run, S4, with significantly improved interferometer sensitivities with respect to previous runs. Using data acquired during this science run, we place a limit on the amplitude of a stochastic background of gravitational waves. For a frequency independent spectrum, the new Bayesian 90% upper limit is Ω_(GW) × [H_0/(72 km s^(−1) Mpc^(−1))]^2 < 6.5 × 10^(-5). This is currently the most sensitive result in the frequency range 51-150 Hz, with a factor of 13 improvement over the previous LIGO result. We discuss the complementarity of the new result with other constraints on a stochastic background of gravitational waves, and we investigate implications of the new result for different models of this background.

Abstract

Hospital-acquired infections are a major contributor to inpatient morbidity, mortality, and health care costs. Ventilator-associated pneumonia (VAP) is among the most common. It is associated with longer duration of mechanical ventilation (MV), longer intensive care unit stays, increase in cost per case of VAP of at least $40 000, and over 2-fold increased risk of mortality.1,2 Hospital rates of VAP are subject to mandated reporting and measured against national benchmarks. However, because the definition of VAP is complex and includes subjective signs and symptoms, the reported incidence in children varies widely from 0.3 to 45.1 cases per 1000 ventilator days.3 VAP may not include all clinically important infections associated with MV.4 Another infection, ventilator-associated tracheobronchitis (VAT), has been described using varying definitions with unclear clinical significance. The incidence of VAT in pediatric intensive care unit (PICU) populations has been reported at 3.4% to 7.3% of ventilated patients, and as high as 21.2% in trauma patients.5-9 VAT has been associated with longer duration of MV and length of stay but not increased mortality.5-7 Variable definitions have been used in studies of VAT, but generally include clinical signs of respiratory infection in the absence of pneumonia on chest radiograph combined with a positive respiratory culture.8,9 Recent studies of VAT in pediatrics have all used a definition based on the Centers for Disease Control and Prevention/National Healthcare Safety Network (CDC/NHSN) definition of “lower respiratory tract infection other than pneumonia” and applied it to children on MV.5-7,10 Definitions of VAT, and those of VAP, are complicated by their reliance on poor interpretability and subjectivity of data including clinical signs and chest radiographs. Microbiologic testing is complicated due to the lack of standard microbiologic methods.3 Respiratory specimens can be obtained by bronchoscopic or non-bronchoscopic bronchoalveolar lavage (BAL), by protected specimen brush, or by endotracheal aspirate (ETA) via new or inline suction catheters. ETA may be preferred due to perceived safety, feasibility, and cost concerns.4 However, validity of cultures obtained by ETA may be questioned due to bacterial colonization of endotracheal tubes. Quantitative bacterial cultures may improve specificity of ETA cultures for infection over colonization, and a threshold of >105 cfu/mL has been suggested.9 Publications on VAT have invariably used ETA as the method to obtain specimens, but have varied in the use of quantitative culture. In our institution, BAL is used for the routine evaluation of ventilator-associated infections including VAP and VAT. Surveillance cultures and ETA are not performed due to concerns of interpretability of results. Because of this, we are in a unique position to provide the first report of BAL results in a large cohort of PICU patients. We hypothesized that VAP represents only a small portion of positive BALs, suggesting that other potentially significant ventilator-associated infections are not well characterized.

Abstract

The LIGO interferometers are operating as gravitational wave observatories, with a noise level near an order of magnitude of the goal and the first scientific data recently taken. This data has been analyzed for four different categories of gravitational wave sources; millisecond bursts, inspiralling binary neutron stars, periodic waves from a known pulsar, and stochastic background.

Abstract

We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search focused on binary systems with component masses between 3 and 20 solar masses. Optimally oriented binaries with distances up to 1 Mpc could be detected with efficiency of at least 90%. We found no events that could be identified as gravitational waves in the 385.6 hours of data that we searched., 18 pages, 8 figures

Abstract

We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple trigger exchange method, we perform an inter-collaboration coincidence search during times when TAMA300 and only one of the LIGO sites were operational. We find no evidence of any gravitational wave signals. We place an observational upper limit on the rate of binary neutron star coalescence with component masses between 1 and 3 M_sun of 49 per year per Milky Way equivalent galaxy at a 90% confidence level. The methods developed during this search will find application in future network inspiral analyses., 9 pages, 5 figures. Updated with published version

We use data from the second science run of the LIGO gravitational-wave detectors to search for the gravitational waves from primordial black hole (PBH) binary coalescence with component masses in the range 0.2--$1.0 M_\odot$. The analysis requires a signal to be found in the data from both LIGO observatories, according to a set of coincidence criteria. No inspiral signals were found. Assuming a spherical halo with core radius 5 kpc extending to 50 kpc containing non-spinning black holes with masses in the range 0.2--$1.0 M_\odot$, we place an observational upper limit on the rate of PBH coalescence of 63 per year per Milky Way halo (MWH) with 90% confidence., Comment: 7 pages, 4 figures, to be submitted to Phys. Rev. D
