EUVE Observations of the Magnetic Cataclysmic Variable QQ Vulpeculae
We present simultaneous X-ray (lambda_peak ~ 44A) and EUV (lambda_peak = 89A)
light curves for the magnetic cataclysmic variable QQ Vulpeculae, obtained with
the EUVE satellite. We find that the unique shape of the X-ray light curve is
different from previously obtained X-ray light curves of QQ Vul and provides
evidence for two-pole accretion. Detailed examination of the photometric data
indicates that QQ Vul undergoes a stellar eclipse of the X-ray emitting region,
indicative of a high binary inclination. We discuss possible implications for
the nature of this system given the observed shape of its EUV and X-ray light
curves.Comment: 12 pages including 4 figures, accepted to PAS

A Public Option for Employer Health Plans
Following the 2020 presidential election, health care reform discussions have centered on two competing proposals: Medicare for All and an individual public option (“Medicare for all who want it”). Interestingly, these two proposals take starkly different approaches to employer-provided health coverage, long the bedrock of the U.S. health care system and the stumbling block to many prior reform efforts. Medicare for All abolishes employer-provided coverage, while an individual public option leaves it untouched.This Article proposes a novel solution that finds a middle ground between these two extremes: an employer public option. In contrast to the more familiar public option proposal, which would offer government sponsored health insurance directly to individuals, our plan creates a public option for employers, who can select a public plan—based on Medicare and altered to meet the needs of working populations—instead of a private health plan for their employees. Employer-based private health coverage is in decline and increasingly leaves workers vulnerable. Our proposal offers a gradual way to loosen reliance on this system.We review the policy, regulatory, fiscal, and business arguments in favor of this form of public option, which we argue is less disruptive than Medicare for All but more impactful than an individual public option. Because employer take up would be gradual and voluntary, our plan has lower fiscal costs and should face less resistance from employees and vested interests than Medicare for All. Over time, if the plan meets employers’ and employees’ needs, more people would be covered by a public option, moving away from over-reliance on private employer plans and toward something akin to Medicare-for-Many in a less politically, legally, and fiscally fraught way
Establishing a core outcome set for peritoneal dialysis : report of the SONG-PD (standardized outcomes in nephrology-peritoneal dialysis) consensus workshop
Outcomes reported in randomized controlled trials in peritoneal dialysis (PD) are diverse, are measured inconsistently, and may not be important to patients, families, and clinicians. The Standardized Outcomes in Nephrology-Peritoneal Dialysis (SONG-PD) initiative aims to establish a core outcome set for trials in PD based on the shared priorities of all stakeholders. We convened an international SONG-PD stakeholder consensus workshop in May 2018 in Vancouver, Canada. Nineteen patients/caregivers and 51 health professionals attended. Participants discussed core outcome domains and implementation in trials in PD. Four themes relating to the formation of core outcome domains were identified: life participation as a main goal of PD, impact of fatigue, empowerment for preparation and planning, and separation of contributing factors from core factors. Considerations for implementation were identified: standardizing patient-reported outcomes, requiring a validated and feasible measure, simplicity of binary outcomes, responsiveness to interventions, and using positive terminology. All stakeholders supported inclusion of PD-related infection, cardiovascular disease, mortality, technique survival, and life participation as the core outcome domains for PD
LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint
magnitudes with a fast cadence will enable many of the exciting science
opportunities of the next decade. The Large Synoptic Survey Telescope (LSST)
will have an effective aperture of 6.7 meters and an imaging camera with field
of view of 9.6 deg^2, and will be devoted to a ten-year imaging survey over
20,000 deg^2 south of +15 deg. Each pointing will be imaged 2000 times with
fifteen second exposures in six broad bands from 0.35 to 1.1 microns, to a
total point-source depth of r~27.5. The LSST Science Book describes the basic
parameters of the LSST hardware, software, and observing plans. The book
discusses educational and outreach opportunities, then goes on to describe a
broad range of science that LSST will revolutionize: mapping the inner and
outer Solar System, stellar populations in the Milky Way and nearby galaxies,
the structure of the Milky Way disk and halo and other objects in the Local
Volume, transient and variable objects both at low and high redshift, and the
properties of normal and active galaxies at low and high redshift. It then
turns to far-field cosmological topics, exploring properties of supernovae to
z~1, strong and weak lensing, the large-scale distribution of galaxies and
baryon oscillations, and how these different probes may be combined to
constrain cosmological models and the physics of dark energy.Comment: 596 pages. Also available at full resolution at

Public ritual and the proclamation of Richard Cromwell in English towns, September 1658
The requirement to proclaim Richard Cromwell lord protector in September 1658 forced town leaders to engage with an unstable political context through the production of a large-scale public event. This article examines the ceremonies used in a range of provincial towns to offer a new perspective on urban culture in 1650s England. By analyzing both contemporary print and the records of civic government, it reveals how urban inhabitants could maintain a variety of performative responses to state directive whilst approaching the moment of succession actively and pragmatically to confront issues specific to their respective locales. Crucially, there was no standard ritual experience and civic authorities remained relatively free to modify existing codes and apply them in the way/s that made most sense to their particular situation. In addition to confirming the essentially ambiguous nature of ceremonial expectation in this context, the findings presented in this article complicate our understanding of urban government during the last months of the protectorate by emphasizing the capacity for towns of varied religious and/or political complexion to use public ritual to further corporate interests and negotiate a range of specific concerns in a national and a local framework
Trauma ICU Prevalence Project: the diversity of surgical critical care.
Background:Surgical critical care is crucial to the care of trauma and surgical patients. This study was designed to provide a contemporary assessment of patient types, injuries, and conditions in intensive care units (ICU) caring for trauma patients. Methods:This was a multicenter prevalence study of the American Association for the Surgery of Trauma; data were collected on all patients present in participating centers' trauma ICU (TICU) on November 2, 2017 and April 10, 2018. Results:Forty-nine centers submitted data on 1416 patients. Median age was 58 years (IQR 41-70). Patient types included trauma (n=665, 46.9%), non-trauma surgical (n=536, 37.8%), medical (n=204, 14.4% overall), or unspecified (n=11). Surgical intensivists managed 73.1% of patients. Of ICU-specific diagnoses, 57% were pulmonary related. Multiple high-intensity diagnoses were represented (septic shock, 10.2%; multiple organ failure, 5.58%; adult respiratory distress syndrome, 4.38%). Hemorrhagic shock was seen in 11.6% of trauma patients and 6.55% of all patients. The most common traumatic injuries were rib fractures (41.6%), brain (38.8%), hemothorax/pneumothorax (30.8%), and facial fractures (23.7%). Forty-four percent were on mechanical ventilation, and 17.6% had a tracheostomy. One-third (33%) had an infection, and over half (54.3%) were on antibiotics. Operations were performed in 70.2%, with 23.7% having abdominal surgery. At 30 days, 5.4% were still in the ICU. Median ICU length of stay was 9 days (IQR 4-20). 30-day mortality was 11.2%. Conclusions:Patient acuity in TICUs in the USA is very high, as is the breadth of pathology and the interventions provided. Non-trauma patients constitute a significant proportion of TICU care. Further assessment of the global predictors of outcome is needed to inform the education, research, clinical practice, and staffing of surgical critical care providers. Level of evidence:IV, prospective observational study
