Message transfer framework for mobile devices using bluetooth low energy

textDespite the increasing availability of mobile devices offering handheld peer to peer communication capabilities, interoperability between heterogeneous mobile device platforms is hampered by the security requirements of their underlying operating systems. Bluetooth Low Energy (BLE) was introduced so that mobile devices could read from sensors with fewer security requirements, presenting an opportunity to allow disparate devices to connect and transfer data. This paper presents a message transfer framework to facilitate arbitrary data transfer using the GATT mechanisms as provided by BLE in the Bluetooth 4.0 specification. The provided implementation library and applications for Android along with a proof of concept application for iOS 8 sustain reliable transfer speeds of 1 KB/s, allowing for a 100KB payload (a small picture, for example) to be sent wirelessly between an Android and iOS device in just over a minute.Electrical and Computer Engineerin

The Figure of the Musician in German Literature

This survey of the literary treatment of musicians in German novels and novellas begins with the Romantics and ends with the publication of Thomas Mann's "Doktor Faustus". Schoolfield explores the work of a large selection of writers, including Hoffmann, Tieck, Kleist, Brentano, Grillparzer, Werfel and Hesse among many others. Through these works he tracks the progression of the figure of the musician as professional, artist, genius, composer, and pedagogue and how the pursuit of their art is interpreted by major literary movements

The German Lyric of the Baroque in English Translation

Here are verse translations, with original texts on facing pages, of representative lyrics by ninety-nine poets of the German Baroque. At its original publication, this volume by Schoolfield presented many of the poets to an English-speaking audience for the first time. An extensive introduction discusses the Baroque culture of the German-language realm and brief biographies of the poets conclude the volume

Growth and Identification of Bacteria in N-Halamine Dental Unit Waterline Tubing Using an Ultrapure Water Source

This study examined bacterial growth and type on biofilm-controlling dental unit waterline (DUWL) tubing (T) and control manufacturer's tubing (C) in a laboratory DUWL model using ultrapure source water that was cycled through the lines. Sections of tubing lines were detached and examined for biofilm growth using SEM imaging at six sampling periods. Bacteria from inside surfaces of T and C, source unit, and reservoir were cultured and enumerated. At six months, organisms were molecularly identified from the alignment matches obtained from the top three BLAST searches for the 16S region. There was a 1–3 log increase in organism growth in a clean, nonsterile reservoir within an hour. Biofilm was established on the inside surfaces of C within three weeks, but not on T. Proteobacteria, and Sphingomonas spp. were identified in the source reservoir and C line, and a variation of the genera was found in T line

Evaluation of Provider Adherence to an Intraoperative Glucose Monitoring Guideline at a Midwestern Academic Hospital

Background and Review of Literature: Patients with diabetes (PWD) are at higher risk of requiring surgery and developing complications in the perioperative period making euglycemia an important component of intraoperative care. There is an association between dysglycemias and adverse perioperative outcomes. Implementation science evidence indicates that education with audit feedback strategies towards barrier identification to clinical practice guideline (CPG) uptake will improve implementation success. Purpose: The purpose of this quality improvement project was to evaluate and improve adherence to intraoperative glucose monitoring outlined by the current intraoperative glucose management guideline at a midwestern academic hospital through barrier identification with tailored educational programs and audit feedback strategies. Methods: Baseline patient data via a retrospective chart review were collected, organized, and analyzed along with, provider attitudes and barriers towards the blood glucose guideline via a provider Likert-type survey. Implementation Plan/Procedure: An education component tailored to the identified barriers was presented in a PDF PowerPoint and distributed via email and in-service roving education to anesthesia providers in the operating room caring for PWD. Implications/Conclusion: The purpose, aim, and objectives of the DNP project were met in regard to implementing an educational initiative to all anesthesia providers. An improvement was seen at the four-week interval during the roving in-service education. It is expected for adherence rates to continue to improve as additional system electronic health record changes are implemented in the upcoming months. In addition, the goals of identifying the top three barriers to the intraoperative guideline and providing a baseline adherence rate were achieved

Studies in the German Drama: A Festschrift in Honor of Walter Silz

Sixteen of his former colleagues and students join in this volume in honoring Walter Silz. Concentrating on a single theme—the German drama—this volume contains essays and interpretations of plays ranging from Hrotsvit von Gandersheim to Bertolt Brecht. Eight of the sixteen essays deal with dramas from the area of Silz's main concentration—the nineteenth century. Also included are a tribute to Silz and a bibliography of his writings

Preliminary investigation of plasma levels of sex hormones and human growth factor(s), and P300 latency as correlates to cognitive decline as a function of gender

<p>Abstract</p> <p>Background</p> <p>Aging is marked by declines in levels of many sex hormones and growth factors, as well as in cognitive function. The P300 event-related potential has been established as a predictor of cognitive decline. We decided to determine if this measure, as well as 2 standard tests of memory and attention, may be correlated with serum levels of sex hormones and growth factors, and if there are any generalizations that could be made based on these parameters and the aging process.</p> <p>Findings</p> <p>In this large clinically based preliminary study several sex-stratified associations between hormone levels and cognition were observed, including (1) for males aged 30 to 49, both IGF-1 and IGFBP-3 significantly associated negatively with prolonged P300 latency; (2) for males aged 30 to 49, the spearman correlation between prolonged P300 latency and low free testosterone was significant; (3) for males aged 60 to 69, there was a significant negative correlation between P300 latency and DHEA levels; (4) for females aged 50 to 59 IGFBP-3 significantly associated negatively with prolonged P300 latency; (5) for females at all age periods, estrogen and progesterone were uncorrelated with P300 latency; and (6) for females aged 40 to 69, there was significant negative correlation between DHEA levels and P300 latency. Moreover there were no statistically significant correlations between any hormone and Wechsler Memory Scale-III (WMS-111). However, in females, there was a significant positive correlation between estrogen levels and the number of Attention Deficit Disorder (ADD) complaints.</p> <p>Conclusion</p> <p>Given certain caveats including confounding factors involving psychiatric and other chronic diseases as well as medications, the results may still have important value. If these results could be confirmed in a more rigorously controlled investigation, it may have important value in the diagnosis, prevention and treatment of cognitive impairments and decline.</p

Literary Culture in the Holy Roman Empire, 1555-1720

These essays discuss approaches to early modern literature in central Europe, focusing on four pivotal areas: connections between humanism and the new scientific thought the relationship of late sixteenth- and early seventeenth-century literature to ancient and Renaissance European traditions the social and political context of early modern writing and the poets' self-consciousness about their work. As a whole, the volume argues that early modern writing in central Europe should not be viewed solely as literature but as the textual product of specific social, political, educational, religious, and economic circumstances.
