    Humesiana, a Remarkable New Cumacean Genus from the Caribbean Sea

    Get PDF
    Most nannastacid cumaceans collected from tropical waters belong to just a few genera, among them the nearly ubiquitous genus Cumella. A new nannastacid genus is described from the West Indian island of Guadeloupe. Members of the genus possess a very long and robust pleonite 6 and short and stubby uropods and share the loss of the ischium on pereiopod 2 and maxilliped 2. This new genus is clearly allied to three species within the genus Cumella, all of which have elongate pleonite 6 and short, but not robust, uropods. These three species are known from the Caribbean Sea, Red Sea, and Gulf of Thailand

    Framework Programmable Platform for the advanced software development workstation: Framework processor design document

    Get PDF
    The design of the Framework Processor (FP) component of the Framework Programmable Software Development Platform (FFP) is described. The FFP is a project aimed at combining effective tool and data integration mechanisms with a model of the software development process in an intelligent integrated software development environment. Guided by the model, this Framework Processor will take advantage of an integrated operating environment to provide automated support for the management and control of the software development process so that costly mistakes during the development phase can be eliminated

    Early CRT monitoring using time-domain optical coherence tomography does not add to visual acuity for predicting visual loss in patients with central retinal vein occlusion treated with intravitreal ranibizumab:A secondary analysis of trial data

    Get PDF
    Our primary purpose was to assess the clinical (predictive) validity of central retinal thickness (CRT) and best corrected visual acuity (BCVA) at 1 week and 1 month after starting treatment with ranibizumab for central retinal vein occlusion. The authors also assessed detectability of response to treatment

    Identifying robust response options to manage environmental change using an ecosystem approach:a stress-testing case study for the UK

    Get PDF
    A diverse range of response options was evaluated in terms of their utility for sustaining ecosystem services in the UK. Robustness of response options was investigated by applying a ‘stress-testing’ method which evaluated expected performance against combined scenarios of socioeconomic and climate change. Based upon stakeholder feedback, a reference scenario representing current trends in climate and socioeconomic drivers (‘business-as-usual’) was used as a dynamic baseline against which to compare results of other scenarios. The robustness of response options was evaluated by their utility in different environmental and social contexts as represented by the scenarios, and linked to their adaptability to adjust to changing conditions. Key findings demonstrate that adaptability becomes increasingly valuable as the magnitude and rate of future change diverges from current trends. Stress-testing also revealed that individual responses in isolation are unlikely to be robust meaning there are advantages from integrating cohesive combinations (bundles) of response options to maximise their individual strengths and compensate for weaknesses. This identifies a role for both top-down and bottom-up responses, including regulation, spatial targeting, incentives and partnership initiatives, and their use in combination through integrated assessment and planning consistent with the adoption of an Ecosystem Approach. Stress-testing approaches can have an important role in future-proofing policy appraisals but important knowledge gaps remain, especially for cultural and supporting ecosystem services. Finally, barriers and enablers to the implementation of more integrated long-term adaptive responses were identified drawing on the ‘4 Is’ (Institutions, Information, Incentives, Identity) conceptual framework. This highlighted the crucial but usually understated role of identity in promoting ownership and uptake of responses

    Prospective Childhood Risk Factors for Gang Involvement among North American Indigenous Adolescents

    Get PDF
    The purpose of the study was to examine prospective childhood risk factors for gang involvement across the course of adolescence among a large eight-year longitudinal sample of 646 Indigenous (i.e., American Indian and Canadian First Nations) youth residing on reservation/reserve land in the Midwest of the United States and Canada. Risk factors at the first wave of the study (ages 10–12) were used to predict gang involvement (i.e., gang membership and initiation) in subsequent waves (ages 11–18). A total of 6.7% of the participants reported gang membership and 9.1% reported gang initiation during the study. Risk factors were distributed across developmental domains (e.g., family, school, peer, and individual) with those in the early delinquency domain having the strongest and most consistent effects. Moreover, the results indicate that the cumulative number of risk factors in childhood increases the probability of subsequent gang involvement. Culturally relevant implications and prevention/intervention strategies are discussed

    An approach to verification and validation of MHD codes for fusion applications

    Get PDF
    We propose a new activity on verification and validation (V&V) of MHD codes presently employed by the fusion community as a predictive capability tool for liquid metal cooling applications, such as liquid metal blankets. The important steps in the development of MHD codes starting from the 1970s are outlined first and then basic MHD codes, which are currently in use by designers of liquid breeder blankets, are reviewed. A benchmark database of five problems has been proposed to cover a wide range of MHD flows from laminar fully developed to turbulent flows, which are of interest for fusion applications: (A) 2D fully developed laminar steady MHD flow, (B) 3D laminar, steady developing MHD flow in a non-uniform magnetic field, (C) quasi-two-dimensional MHD turbulent flow, (D) 3D turbulent MHD flow, and (E) MHD flow with heat transfer (buoyant convection). Finally, we introduce important details of the proposed activities, such as basic V&V rules and schedule. The main goal of the present paper is to help in establishing an efficient V&V framework and to initiate benchmarking among interested parties. The comparison results computed by the codes against analytical solutions and trusted experimental and numerical data as well as code-to-code comparisons will be presented and analyzed in companion paper/papers.Peer ReviewedPostprint (author's final draft
