Kepler eclipsing binary stars. VII. the catalogue of eclipsing binaries found in the entire Kepler data set

The primary Kepler Mission provided nearly continuous monitoring of ~200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary systems within the 105 deg2 Kepler field of view. This release incorporates the full extent of the data from the primary mission (Q0-Q17 Data Release). As a result, new systems have been added, additional false positives have been removed, ephemerides and principal parameters have been recomputed, classifications have been revised to rely on analytical models, and eclipse timing variations have been computed for each system. We identify several classes of systems including those that exhibit tertiary eclipse events, systems that show clear evidence of additional bodies, heartbeat systems, systems with changing eclipse depths, and systems exhibiting only one eclipse event over the duration of the mission. We have updated the period and galactic latitude distribution diagrams and included a catalog completeness evaluation. The total number of identified eclipsing and ellipsoidal binary systems in the Kepler field of view has increased to 2878, 1.3% of all observed Kepler targets

Kepler Eclipsing Binary Stars. Vii. The Catalog Of Eclipsing Binaries Found In The Entire Kepler Data Set

The Kepler mission has provided unprecedented, nearly continuous photometric data of ~200,000 objects in the ~105 deg2 field of view (FOV) from the beginning of science operations in May of 2009 until the loss of the second reaction wheel in May of 2013. The Kepler Eclipsing Binary Catalog contains information including but not limited to ephemerides, stellar parameters, and analytical approximation fits for every known eclipsing binary system in the Kepler FOV. Using target pixel level data collected from Kepler in conjunction with the Kepler Eclipsing Binary Catalog, we identify false positives among eclipsing binaries, i.e., targets that are not eclipsing binaries themselves, but are instead contaminated by eclipsing binary sources nearby on the sky and show eclipsing binary signatures in their light curves. We present methods for identifying these false positives and for extracting new light curves for the true source of the observed binary signal. For each source, we extract three separate light curves for each quarter of available data by optimizing the signal-to-noise ratio, the relative percent eclipse depth, and the flux eclipse depth. We present 289 new eclipsing binaries in the Kepler FOV that were not targets for observation, and these have been added to the catalog

The First Habitable-Zone Earth-Sized Planet From TESS. I. Validation Of The TOI-700 System

We present the discovery and validation of a three-planet system orbiting the nearby (31.1 pc) M2 dwarf star TOI-700 (TIC 150428135). TOI-700 lies in the TESS continuous viewing zone in the Southern Ecliptic Hemisphere; observations spanning 11 sectors reveal three planets with radii ranging from 1 R⊕ to 2.6 R⊕ and orbital periods ranging from 9.98 to 37.43 days. Ground-based follow-up combined with diagnostic vetting and validation tests enables us to rule out common astrophysical false-positive scenarios and validate the system of planets. The outermost planet, TOI-700 d, has a radius of 1.19 ± 0.11 R⊕ and resides within a conservative estimate of the host star\u27s habitable zone, where it receives a flux from its star that is approximately 86% of Earth\u27s insolation. In contrast to some other low-mass stars that host Earth-sized planets in their habitable zones, TOI-700 exhibits low levels of stellar activity, presenting a valuable opportunity to study potentially rocky planets over a wide range of conditions affecting atmospheric escape. While atmospheric characterization of TOI-700 d with the James Webb Space Telescope (JWST) will be challenging, the larger sub-Neptune, TOI-700 c (R = 2.63 R⊕), will be an excellent target for JWST and future space-based observatories. TESS is scheduled to once again observe the Southern Hemisphere, and it will monitor TOI-700 for an additional 11 sectors in its extended mission. These observations should allow further constraints on the known planet parameters and searches for additional planets and transit timing variations in the system

Development and implementation of a patient reported outcome intervention (QLIC-ON PROfile) in clinical paediatric oncology practice

Contains fulltext : 88481.pdf (publisher's version ) (Closed access)OBJECTIVE: The use of patient reported outcomes (PRO) in routine clinical practice is becoming increasingly common, but there is limited knowledge about the development and implementation of PRO. The objective of the current paper is to provide a thorough description of the development and implementation of a PRO on health related quality of life (HRQOL)--the QLIC-ON PROfile--in clinical paediatric oncology practice. METHODS: The development of the QLIC-ON PROfile is explained by elucidating important choices: the HRQOL instrument, the professional that uses the QLIC-ON PROfile, the optimal form of HRQOL feedback and whether or not a clinically important difference is reported. The description of the implementation of the QLIC-ON PROfile focuses on the education and commitment of the professional that uses the QLIC-ON PROfile. Study design and outcome measures are also elaborated on. RESULTS: Important considerations regarding the development and implementation of PRO interventions are reported. These considerations have also resulted in educational material. CONCLUSION: Our study adds to current knowledge of PRO research. This paper can be used as a practical guide for researchers and other professionals, who are interested in setting up PRO interventions in any clinical setting.1 november 201

Psychometric qualities of the Dutch version of the Pediatric Inventory for Parents (PIP): a multi-center study

Objectives: Diagnosis and treatment of childhood cancer are continuous stressors in the lives of the entire family involved. Disease-related tools for the assessment of parental stress and adaptation are scarce. For that reason, the Pediatric Inventory for Parents (PIP), a disease-related measure, was translated into Dutch and its psychometric qualities were determined to prove its value. Methods: The PIP and three other measures (State-Trait Anxiety Inventory, General Health Questionnaire and Parenting Stress Index, Short Form) were administered to 174 parents of 107 children diagnosed with cancer in three university medical centers in the Netherlands. Results: Internal consistency (Crohnbach's alpha = 0.94 and 0.95) and test-retest reliability (Pearson's r between 0.67 and 0.87) of the Dutch PIP total scales are satisfactory. Validity was illustrated by a high correlation between PIP-scores and anxiety and general stress. Confirmatory factor analysis showed acceptable fit to the data for the original four-factor and the one-factor models; the four-factor model showed slightly better fit. Conclusion: The PIP can be used in clinical practice to assess disease-related parental stress. Further psychometric testing is highly recommended. Copyright (C) 2009 John Wiley & Sons, Ltd

Replication of the tumor necrosis factor receptor-associated factor 1/complement component 5 region as a susceptibility locus for rheumatoid arthritis in a European family-based study.

Contains fulltext : 71178.pdf (publisher's version ) (Closed access)OBJECTIVE: We recently showed, using a candidate gene approach in a case-control association study, that a 65-kb block encompassing tumor necrosis factor receptor-associated factor 1 (TRAF1) and C5 is strongly associated with rheumatoid arthritis (RA). Compared with case-control association studies, family-based studies have the added advantage of controlling potential differences in population structure and are not likely to be hampered by variation in population allele frequencies, as is seen for many genetic polymorphisms, including the TRAF1/C5 locus. The aim of this study was to confirm this association in populations of European origin by using a family-based approach. METHODS: A total of 1,356 western European white individuals from 452 "trio" families were genotyped for the rs10818488 polymorphism, using the TaqMan allelic discrimination assay. RESULTS: We observed evidence for association, demonstrating departure from Mendel's law, with an overtransmission of the rs10818488 A allele (A = 55%; P = 0.036). By taking into consideration parental phenotypes, we also observed an increased A allele frequency in affected versus unaffected parents (A = 64%; combined P = 0.015). Individuals carrying the A allele had a 1.2-fold increased risk of developing RA (allelic odds ratio 1.24, 95% confidence interval 1.04-1.50). CONCLUSION: Using a family-based study that is robust against population stratification, we provide evidence for the association of the TRAF1/C5 rs10818488 A allele and RA in populations of European descent, further substantiating our previous findings. Future functional studies should yield insight into the biologic relevance of this locus to the pathways involved in RA
