    Get PDF
    Points to rising rates of chronic conditions and obesity; growing numbers of patients with problems paying medical bills, even with insurance; and contributing factors such as declining private coverage and delays in accessing care. Outlines implications

    Checking Up on Retail-Based Health Clinics: Is the Boom Ending?

    Get PDF
    Outlines trends in the growth of retail-based clinics providing basic care at pharmacies and other retail settings. Examines who uses them, where, for what services, and why; insurance coverage and reimbursement rates; and variations in state regulation

    Computer program for stress, vibration, and buckling characteristics of general shells of revolution

    Get PDF
    Structures Research Associates (SRA) system of programs is composed of six compatible computer programs for structural analyses of axisymmetric shell structures. Theories and methods upon which these programs are based are presented in documentation. They apply to a common structural model but analyze different modes of structural response

    Examines the increasing employer demand for workplace clinics, clinic management models, types of services, challenges, regulations, and the clinics' potential impact, including their ability to raise productivity and help contain healthcare costs

    Feasibility study of shell buckling analysis using the modified structure method

    Get PDF
    The modified structure method, which is based on Koiter's theory of imperfections, was used to calculate approximate buckling loads of several shells of revolution. The method does not appear to be practical for shells because, in many cases, the prebuckling nonlinearity may be too large to be treated accurately as a small imperfection

    Optimization of Network Robustness to Waves of Targeted and Random Attack

    We study the robustness of complex networks to multiple waves of simultaneous (i) targeted attacks in which the highest degree nodes are removed and (ii) random attacks (or failures) in which fractions ptp_t and prp_r respectively of the nodes are removed until the network collapses. We find that the network design which optimizes network robustness has a bimodal degree distribution, with a fraction rr of the nodes having degree k_2= (\kav - 1 +r)/r and the remainder of the nodes having degree k1=1k_1=1, where \kav is the average degree of all the nodes. We find that the optimal value of rr is of the order of pt/prp_t/p_r for pt/pr≪1p_t/p_r\ll 1

    Fine-Grain Checkpointing with In-Cache-Line Logging

    Full text link
    Non-Volatile Memory offers the possibility of implementing high-performance, durable data structures. However, achieving performance comparable to well-designed data structures in non-persistent (transient) memory is difficult, primarily because of the cost of ensuring the order in which memory writes reach NVM. Often, this requires flushing data to NVM and waiting a full memory round-trip time. In this paper, we introduce two new techniques: Fine-Grained Checkpointing, which ensures a consistent, quickly recoverable data structure in NVM after a system failure, and In-Cache-Line Logging, an undo-logging technique that enables recovery of earlier state without requiring cache-line flushes in the normal case. We implemented these techniques in the Masstree data structure, making it persistent and demonstrating the ease of applying them to a highly optimized system and their low (5.9-15.4\%) runtime overhead cost.Comment: In 2019 Architectural Support for Programming Languages and Operating Systems (ASPLOS 19), April 13, 2019, Providence, RI, US
