    Abstract:

    Estimating a massive drive time matrix between locations is a practical but challenging task. The challenges include availability of reliable road network (including traffic) data, programming expertise, and access to high-performance computing resources. This research proposes a method for estimating a nationwide drive time matrix between ZIP code areas in the U.S. - a geographic unit at which many national datasets including health information are compiled and distributed. The method (1) do…

    Abstract:

    Understanding the environmental justice implications of the mortality impacts of air pollution exposure is a public health priority, as some subpopulations may face a disproportionate health burden. We examined which residential environmental and social factors may affect disparities in the air pollution-mortality relationship in North Carolina, US, using a time-stratified case-crossover design. Results indicate that air pollution poses a higher mortality risk for some persons (e.g., elderly)…

    Abstract:

    In January 2020, the EPA plans to issue a supplement to its 2018 proposed rule, Strengthening Transparency in Regulatory Science. The revised rule may prohibit the EPA from using any research for which underlying raw data and models are not made public. In the December 6, 2019 issue of Science, Dr. Marie Lynn Miranda, Director of CEHI, provided explanation of why such a rule would jeopardize regulations that aim to keep the environment a safe place for all of us to live.

    Abstract:

    Background - Growing physician maldistribution and population demographic shifts have contributed to large geographic variation in healthcare access and the emergence of advanced practice providers as contributors to the healthcare workforce. Current estimates of geographic accessibility of physicians and advanced practice providers rely on outdated “provider per capita” estimates that have shortcomings.

    Purpose - To apply state of the art methods to estimate spatial accessibility of physic…

    Abstract:

    OBJECTIVES: Chiropractic care is a service that operates outside of the conventional medical system and is reimbursed by Medicare. Our objective was to examine the extent to which accessibility of chiropractic care affects spending on medical spine care among Medicare beneficiaries.

    STUDY DESIGN: Retrospective cohort study that used beneficiary relocation as a quasi-experiment.

    METHODS: We used a combination of national data on provider location and Medicare claims to perform a quasi-experi…

    Abstract:

    A method for the nanofabrication of periodic arrays of gold nanostars yielding a unique morphology of relevance to SERS applications. With arms radiating from a central core, gold nanostars represent a unique and fascinating class of nanomaterials from which extraordinary plasmonic properties are derived. Despite their relevance to sensing applications, methods for fabricating homogeneous populations of nanostars on large-area planar surfaces in truly periodic arrays is lacking. Herein, the f…

    Abstract:

    Silver nanofilament formation dynamics are reported for an ionic liquid (IL)-filled solid polymer electrolyte prepared by a direct-write process using a conductive atomic force microscope (C-AFM). Filaments are electrochemically formed at hundreds of xy locations on a ≈40 nm thick polymer electrolyte, polyethylene glycol diacrylate (PEGDA)/[BMIM]PF6. Although the formation time generally decreases with increasing bias from 0.7 to 3.0 V, an unexpected non-monotonic maximum is observed ≈2.0 V. …

    Abstract:

    Loss of integrin-mediated attachment to extracellular matrix (ECM) proteins can trigger a variety of cellular changes that impact cell viability. Foremost among these is the activation of anoikis, caspase-mediated cell death induced by ECM-detachment. In addition to anoikis, loss of ECM-attachment causes profound alterations in cellular metabolism that can lead to anoikis-independent cell death. Here, we describe a surprising role for serum and glucocorticoid kinase-1 (SGK1) in the promotion …

    Abstract:

    hydrophobic (i.e., Hoechst 33342) dyes or drugs, including a binary dye/drug pair (i.e., indocyanine green/mitoxantrone). The core of HBPn, containing a mixture of uncharged 2-pentanone chains and 1,2,3-triazole rings, could be loaded with uncharged and very hydrophobic dyes (i.e., Nile Red) or drugs. Improved aqueous solubility of camptothecin was achieved 10-fold from 8.4 to 75 ng/mL. Additionally, cell toxicity studies showed that HBPn was able to release the camptothecin drug inside A549 …

    Abstract:

    Amyotrophic lateral sclerosis (ALS) is characterized by the degeneration of upper and lower 36 motor neurons, yet an increasing number of studies in both mouse models and patients with 37 ALS suggest that altered metabolic homeostasis is a feature of disease. Pre-clinical and clinical 38 studies have shown that modulation of energy balance can be beneficial in ALS. However, our 39 capacity to target specific metabolic pathways or mechanisms requires detailed understanding 40 of metabolic dysr…

    Abstract:

    Spreading resistance microscopy (SRM) was used to study nanoscale variations in electronic and structural properties of an ultrathin near-surface GaN/AlN quantum well (QW). In the SRM images of the growth surface of the GaN/AlN QW heterostructure, an inhomogeneous current contrast was detected in the form of disk-like regions of increased conductivity with the sizes in the range of 50–160 nm and a density of 1.7 109 cm 2 . Analysis of the current contrast dependence on the polarity of the sam…

    The 1T phase of tantalum disulfide (1T-TaS 2 ) possesses a variety of charge-density-wave (CDW) orders, and as a result, it attracts an increasing amount of academic and technological interest. The 1T phase of tantalum disulfide (1T-TaS 2 ) possesses a variety of charge-density-wave (CDW) orders, and as a result, it attracts an increasing amount of academic and technological interest. Researchers have devoted tremendous efforts towards understanding the impacts of doping, alloying, intercalat…
