    In this report from the Childhood Cancer Survivor Study (CCSS), we described marriage and divorce rates in survivors of childhood cancer, as compared to a sibling control group and the general U.S. population. We also sought to identify patient and treatment characteristics that were associated with survivor marital status. This study included 8,930 five-year survivors of childhood malignancy and 2,855 sibling controls participating in the CCSS. Data on marital status, sociodemographic factors, and current health status were obtained from questionnaires; detailed disease and treatment histories were available from medical records. Marital status of the U.S. population was obtained from the 2002 Current Population Survey of the U.S. Census. We found that survivors were more likely to have never married than both sibling (odds ratio [OR] = 1.79; 95 % CI = 1.65-1.94; p \u3c 0.0001) and population controls (OR = 2.29; 95 % CI = 2.19-2.38; p \u3c 0.0001), with persistence of trends across age and gender strata. Once married, survivors divorced at rates equivalent to controls. In adjusted analysis, we found that several survivor characteristics predicted never-married status, including treatment involving cranial radiation (OR = 2.41; p \u3c 0.0001), CNS tumor diagnosis (OR = 2.05; p \u3c 0.0001), history of growth hormone deficiency (OR = 2.02; p \u3c 0.0001), and unemployment secondary to disability (OR = 1.78; p = 0.0001). Survivor characteristics predictive of divorce included unemployment (OR = 1.91; p \u3c 0.0001, for unemployed or disabled), lower educational achievement (OR = 1.74; p \u3c 0.0001, for non-college graduates), and psychological distress (OR = 1.60; p \u3c 0.0001). This study confirms prior reports of lower marriage rates in survivors of childhood cancer, providing further evidence that this population struggles with psychosocial adjustment to adult life

    The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned

    Full text link
    We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NIRISS). Thanks to self-calibrating observables, AMI accesses inner working angles down to and even within the classical diffraction limit. The scientific potential of this mode has recently been demonstrated by the Early Release Science (ERS) 1386 program with a deep search for close-in companions in the HIP 65426 exoplanetary system. As part of ERS 1386, we use the same dataset to explore the random, static, and calibration errors of NIRISS AMI observables. We compare the observed noise properties and achievable contrast to theoretical predictions. We explore possible sources of calibration errors, and show that differences in charge migration between the observations of HIP 65426 and point-spread function calibration stars can account for the achieved contrast curves. Lastly, we use self-calibration tests to demonstrate that with adequate calibration, NIRISS AMI can reach contrast levels of ∌9−10\sim9-10 mag. These tests lead us to observation planning recommendations and strongly motivate future studies aimed at producing sophisticated calibration strategies taking these systematic effects into account. This will unlock the unprecedented capabilities of JWST/NIRISS AMI, with sensitivity to significantly colder, lower mass exoplanets than ground-based setups at orbital separations inaccessible to JWST coronagraphy.Comment: 20 pages, 12 figures, submitted to AAS Journal

    The \textit{JWST} Early Release Science Program for Direct Observations of Exoplanetary Systems III: Aperture Masking Interferometric Observations of the star HIP\,65426 at 3.8 Όm\boldsymbol{3.8\,\rm{\mu m}}

    Full text link
    We present aperture masking interferometry (AMI) observations of the star HIP 65426 at 3.8 Όm3.8\,\rm{\mu m} as a part of the \textit{JWST} Direct Imaging Early Release Science (ERS) program obtained using the Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument. This mode provides access to very small inner working angles (even separations slightly below the Michelson limit of 0.5λ/D{}0.5\lambda/D for an interferometer), which are inaccessible with the classical inner working angles of the \textit{JWST} coronagraphs. When combined with \textit{JWST}'s unprecedented infrared sensitivity, this mode has the potential to probe a new portion of parameter space across a wide array of astronomical observations. Using this mode, we are able to achieve a contrast of ΔmF380M∌7.8\Delta m_{F380M}{\sim }7.8\,mag relative to the host star at a separation of {\sim}0.07\arcsec but detect no additional companions interior to the known companion HIP\,65426\,b. Our observations thus rule out companions more massive than 10{-}12\,\rm{M\textsubscript{Jup}} at separations ∌10−20 au{\sim}10{-}20\,\rm{au} from HIP\,65426, a region out of reach of ground or space-based coronagraphic imaging. These observations confirm that the AMI mode on \textit{JWST} is sensitive to planetary mass companions orbiting at the water frost line, even for more distant stars at ∌\sim100\,pc. This result will allow the planning and successful execution of future observations to probe the inner regions of nearby stellar systems, opening essentially unexplored parameter space.Comment: 15 pages, 9 figures, submitted to ApJ Letter

    Terrestrial Very-Long-Baseline Atom Interferometry:Workshop Summary

    Get PDF
    This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world to discuss the exciting developments in large-scale atom interferometer (AI) prototypes and their potential for detecting ultralight dark matter and gravitational waves. The primary objective of the workshop was to lay the groundwork for an international TVLBAI proto-collaboration. This collaboration aims to unite researchers from different institutions to strategize and secure funding for terrestrial large-scale AI projects. The ultimate goal is to create a roadmap detailing the design and technology choices for one or more km-scale detectors, which will be operational in the mid-2030s. The key sections of this report present the physics case and technical challenges, together with a comprehensive overview of the discussions at the workshop together with the main conclusions

    Data from: Postmating isolation and genetically variable host use in ecologically divergent host forms of Neochlamisus bebbianae leaf beetles

    No full text
    Ecological speciation studies have more thoroughly addressed premating than postmating reproductive isolation. This study examines multiple postmating barriers between host forms of Neochlamisus bebbianae leaf beetles that specialize on Acer versus Salix trees. We demonstrate cryptic isolation and reduced hybrid fitness via controlled matings of these host forms. These findings reveal host-associated postmating isolation, although a non-ecological, ‘intrinsic’ basis for these patterns cannot be ruled out. Host preference and performance results among cross types further suggest sex-linked maternal effects on these traits, while family effects indicate their genetic basis and associated variation. Genes of major effect appear to influence these traits. Together with previous findings of premating isolation and adaptive differentiation in sympatry, our results meet many assumptions of ‘speciation with gene flow’ models. Here, such gene flow is likely asymmetric, with consequences for the dynamics of future ecological divergence and potential ecological speciation of these host forms
