An Update on GPM and TRMM Data Services at NASA GES DISC

The Goddard Earth Sciences (GES) Data and Information Services Center (DISC) is home to data archives of the NASA-JAXA Global Precipitation Measurement (GPM), the Tropical Rainfall Measuring Mission (TRMM), and other NASA missions and projects. To maximize the use of NASA data products in scientific research and applications as well as for societal benefits, we provide data and information services that make datasets easy to find and use through simplification of data access for users at all levels around the world. Over the years, user-friendly data services have been developed at GES DISC, including data subsetting, format conversion, online visualization and analysis (i.e. Giovanni), user support system, etc. We routinely analyze questions, feedback, and use cases from users and algorithm developers around the world as well as best practices and new technology to improve existing services and formulate new data services. Interaction between users and algorithm developers is an important process for identifying issues in products, collecting user requirements, and improving product quality and usability. Staff members regularly communicate with algorithm developers with user questions and concerns through conferences and workshops. We publish peer-reviewed papers and articles in major Earth science journals and book chapters to describe NASA global and regional precipitation datasets and services with examples. News articles about GPM and TRMM datasets associated with significant events are regularly posted in the GES DISC Web portal and social media. We also actively participate in training activities. In this presentation, we present our latest activities about GPM and TRMM data services, data/service metrics, and future plans at GES DISC

Concise Synthesis of (+)- allo

3-Methyl vinyl aziridine undergoes a mild MgI2-promoted S(N)2' ring opening and concomitant cyclization with fumarate Michael acceptors to give trisubstituted pyrrolidines. The process is efficient and highly diastereoselective. This methodology has been applied to a concise asymmetric synthesis of (+)-allo-kainic acid.</p

Borderline personality disorder traits and suicide risk: The mediating role of insomnia and nightmares

BACKGROUND: Borderline personality disorder (BPD) is associated with high rates of suicide risk and problems related to sleep, including insomnia and nightmares. The purpose of the current study was to assess the potential indirect effect of BPD traits on suicide risk through both/either insomnia and nightmares. METHODS: Participants (N = 281) were recruited via Amazon\u27s Mechanical Turk to complete the study remotely online. Participants completed measures of BPD traits and symptoms, suicide risk (history of suicidal thoughts and behaviors), insomnia symptoms, and distress and impairment related to nightmares. RESULTS: BPD traits and symptoms were moderately to highly correlated to suicide risk, insomnia, and nightmares. In parallel mediation models, BPD traits had a significant indirect effect on suicide risk through insomnia symptoms but not nightmares. LIMITATIONS: The current study assessed problems within the general population and not in a clinical sample. Second, the study relied solely on self-report measures. Futures studies would benefit from investigating these relations in clinical samples utilizing observer-report and interview methods. CONCLUSIONS: BPD traits appear to relate to increased risk for suicide through the relation with sleep concerns, particularly insomnia symptoms. Therefore, assessing and treating sleep problems within individuals with BPD may result in a lower risk for suicide

The spectrum problem for digraphs of order 4 and size 5

The paw graph consists of a triangle with a pendant edge attached to one of the three vertices. We obtain a multigraph by adding exactly one repeated edge to the paw. Now, let $D$ be a directed graph obtained by orientating the edges of that multigraph. For 12 of the 18 possibilities for $D$, we establish necessary and sufficient conditions on $n$ for the existence of a $(K^{*}_{n},D)$-design. Partial results are given for the remaining 6 possibilities for $D$
