Digital Material Assembly by Passive Means and Modular Isotropic Lattice Extruder System

A set of machines and related systems build structures by the additive assembly of discrete parts. These digital material assemblies constrain the constituent parts to a discrete set of possible positions and orientations. In doing so, the structures exhibit many of the properties inherent in digital communication such as error correction, fault tolerance and allow the assembly of precise structures with comparatively imprecise tools. Assembly of discrete cellular lattices by a Modular Isotropic Lattice Extruder System (MILES) is implemented by pulling strings of lattice elements through a forming die that enforces geometry constraints that lock the elements into a rigid structure that can then be pushed against and extruded out of the die as an assembled, loadbearing structure

Discrete Assemblers Utilizing Conventional Motion Systems

An alternative to additive manufacturing is disclosed, introducing an end-to-end workflow in which discrete building blocks are reversibly joined to produce assemblies called digital materials. Described is the design of the bulk-material building blocks and the devices that are assembled from them. Detailed is the design and implementation of an automated assembler, which takes advantage of the digital material structure to avoid positioning errors within a large tolerance. To generate assembly sequences, a novel CAD/CAM workflow is described for designing, simulating, and assembling digital materials. The structures assembled using this process have been evaluated, showing that the joints perform well under varying conditions and that the assembled structures are functionally precise

Assessing Attitudes Towards Tobacco Advertising in Winooski, VT

Introduction. Smoking rates are 15% in Vermont and higher in low-income populations. Winooski, Vermont is vulnerable to high tobacco use rates given that 23.6% of Winooski residents live below the poverty line. Tobacco advertising, which has been shown to have a direct, dose-dependent association with youth tobacco use, is highly prevalent in stores in Winooski.https://scholarworks.uvm.edu/comphp_gallery/1091/thumbnail.jp

Quantifying and monetizing potential climate change policy impacts on terrestrial ecosystem carbon storage and wildfires in the United States

This paper develops and applies methods to quantify and monetize projected impacts on terrestrial ecosystem carbon storage and areas burned by wildfires in the contiguous United States under scenarios with and without global greenhouse gas mitigation. The MC1 dynamic global vegetation model is used to develop physical impact projections using three climate models that project a range of future conditions. We also investigate the sensitivity of future climates to different initial conditions of the climate model. Our analysis reveals that mitigation, where global radiative forcing is stabilized at 3.7 W/m2 in 2100, would consistently reduce areas burned from 2001 to 2100 by tens of millions of hectares. Monetized, these impacts are equivalent to potentially avoiding billions of dollars (discounted) in wildfire response costs. Impacts to terrestrial ecosystem carbon storage are less uniform, but changes are on the order of billions of tons over this time period. The equivalent social value of these changes in carbon storage ranges from hundreds of billions to trillions of dollars (discounted). The magnitude of these results highlights their importance when evaluating climate policy options. However, our results also show national outcomes are driven by a few regions and results are not uniform across regions, time periods, or models. Differences in the results based on the modeling approach and across initializing conditions also raise important questions about how variability in projected climates is accounted for, especially when considering impacts where extreme or threshold conditions are important.United States.

Hypertension Education and the Burlington Housing Authority

Background: • 2/3 seniors are hypertensive (\u3e140/90 mm Hg) • Hypertension is the most common risk factor for premature heart disease and stroke • Non-modifiable risk factors: race, age, sex, diabetes mellitus, and hypercholesterolemia • Modifiable risk factors: smoking, obesity, and excessive alcohol • Clinical trials show that lifestylemodification and medications can reduce the incidence of adverse outcomes associated with hypertension • Patient education is a high priorityhttps://scholarworks.uvm.edu/comphp_gallery/1026/thumbnail.jp

Spectrum of Neuroradiologic Findings Associated with Monogenic Interferonopathies

The genetic interferonopathies are a heterogeneous group of disorders thought to be caused by the dysregulated expression of interferons and are now commonly considered in the differential diagnosis of children presenting with recurrent or persistent inflammatory phenotypes. With emerging therapeutic options, recognition of these disorders is increasingly important, and neuroimaging plays a vital role. In this article, we discuss the wide spectrum of neuroradiologic features associated with monogenic interferonopathies by reviewing the literature and illustrate these with cases from our institutions. These cases include intracerebral calcifications, white matter T2 hyperintensities, deep WM cysts, cerebral atrophy, large cerebral artery disease, bilateral striatal necrosis, and masslike lesions. A better understanding of the breadth of the neuroimaging phenotypes in conjunction with clinical and laboratory findings will enable earlier diagnosis and direct therapeutic strategies

The Effects of Text Message Reminder on Blood Donor Show Rate

Introduction: Declining blood collection endangers the blood supply at a time when the health care system is requiring an increasingly greater amount of blood products. Blood donation centers are challenged to recruit and develop first-time donors into reliable repeat donors, thereby ensuring a sufficient blood supply. Communication strategies such as e-mail reminders have been shown to be an effective communications tool to promote blood collection. Alternatively, Text Messaging has been shown effective in primary care and preventative medicine. Text messaging improved patient compliance with a schedule of vaccine dosing, as well as improving patient attendance at outpatient clinics. Additionally, text messaging reminders have been shown to be as effective as phone reminders in increasing patient attendance at outpatient appointments. Finally, text messaging has been shown to be useful for managing self-care such as smoking cessation, monitoring asthmatic symptoms, and diabetes control. We investigated whether offering the use a text message reminder to donors would increase attendance at donation events, demonstrating that text messaging can be an effective tool in maintaining a pool of blood donors.https://scholarworks.uvm.edu/comphp_gallery/1008/thumbnail.jp

A Model of the Chicxulub Impact Basin Based on Evaluation of Geophysical Data, Well Logs, and Drill Core Samples

Abundant evidence now shows that the buried Chicxulub structure in northern Yucatan, Mexico, is indeed the intensely sought-after source of the ejecta found world-wide at the Cretaceous-Tertiary (K/T) boundary. In addition to large-scale concentric patterns in gravity and magnetic data over the structure, recent analyses of drill-core samples reveal a lithological assemblage similar to that observed at other terrestrial craters. This assemblage comprises suevite breccias, ejecta deposit breccias (Bunte Breccia equivalents), fine-grained impact melt rocks, and melt-matrix breccias. All these impact-produced lithologies contain diagnostic evidence of shock metamorphism, including planar deformation features in quartz, feldspar, and zircons; diaplectic glasses of quartz and feldspar; and fused mineral melts and whole-rock melts. In addition, elevated concentrations of Ir, Re, and Os, in meteoritic relative proportions, have been detected in some melt-rock samples from the center of the structure. Isotopic analyses, magnetization of melt-rock samples, and local stratigraphic constraints identify this crater as the source of K/T boundary deposits
