Financial and Health Burdens of Chronic Conditions Grow
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?
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
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
Striking Jump in Consumers Seeking Health Care Information
Examines shifts in how Americans seek health information from sources other than their doctors. Looks at growing Internet use and information-seeking for others, education as a factor, and the impact of information-seeking on perceptions of health issues
Workplace Clinics: A Sign of Growing Employer Interest in Wellness
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
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 and 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 of the nodes having degree k_2= (\kav - 1 +r)/r and the
remainder of the nodes having degree , where \kav is the average
degree of all the nodes. We find that the optimal value of is of the order
of for
Fine-Grain Checkpointing with In-Cache-Line Logging
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
