Extended Abstract: Analysis of 1000 Arbiter PUF based RFID Tags

In this extended abstract a large-scale analysis of 4- way Arbiter PUFs is performed with measurement results from 1000 RFID tags. Arbiter PUFs are one of the most important building blocks in PUF-based protocols and have been the subject of many papers. However, in the past often only software simulations or a limited number of test chips were available for analysis. Therefore, the goal of this work is to verify earlier findings in regard to the uniqueness and reliability of Arbiter PUFs by using a much larger measurement set. Furthermore, we used machine learning algorithms to approximate and compare the internal delay differences of the employed PUF. One of the main research questions in this paper is to examine if any “outliers” occurred, i.e., if some tags performed considerably different. This might for example happen due to some unusual manufacturing variations or faults. However, our findings are that for all of the analyzed tags the parameters fell within the range of a Gaussian distribution without significant outliers. Hence, our results are indeed in line with the results of prior work

Connecticut Rising to the Challenge: A Report of the Conecticut Dialogue on Public Libraries

On April 13, 2015, nearly 100 library leaders, state and local policy makers, and civic partners convened at the Connecticut State Capitol to explore the opportunities for working more closely and more intentionally with Connecticut's public libraries. Two themes formed the focal point for the daylong discussions: (1) how to leverage the considerable assets of the state's public libraries to build more knowledgeable, healthy and sustain able communities across the state and (2) how to improve the sustainability of public libraries in Connecticut. Convened by the Aspen Institute Dialogue on Public Libraries in partnership with the Connecticut State Library, the Connecticut Dialogue on Public Libraries examined the work Connecticut's public libraries are already doing individually and collectively to meet community needs, address emerging challenges, and build more connected communities. Participants in the Dialogue also explored the economic and social challenges that are shaping community needs in Connecticut and fiscal challenges affecting library sustainability. Finally, the Dialogue considered new proposals, partnerships, and initiatives to guide collective action by the Connecticut State Library, the 164 local public libraries, and state and community partners. The Connecticut session was the first in a series of state and local dialogues that will examine issues, challenges, and opportunities facing communities and their public libraries, building on the framework provided by the Aspen Institute's October 2014 report, Rising to the Challenge: Re - Envisioning Public Libraries

Drivers of Demand for Imported Horticultural Commodities: A Cross-Country Comparison

International trade of horticultural commodities is increasingly important in many regions of the world, yet relatively little research has studied import patterns of key horticultural crops. Using data between 1991 and 2005, we find that import demand for horticultural commodities in developed countries has been driven primarily by prices and the level of trade openness while income and diet considerations were more important in emerging countries. Furthermore, our results show that the determinants of import demand differed across the selected crops, and therefore information can be lost if data for horticultural commodities are aggregated.Emerging markets, Horticultural commodities, Import demand, International trade, International Relations/Trade, Marketing, Q10, Q13, Q17,

Import Demand for Horticultural Commodities in Developed and Emerging Countries

International trade of horticultural commodities is increasingly important in many regions of the world, yet import patterns of key horticultural crops are understudied in the agricultural economics literature. Using data between 1991 and 2005, we estimate the drivers of per capita import demand for six of the most highly traded horticultural commodities. The own price elasticity estimates were negative in all import demand models and, in most cases, the effects were statistically stronger for importers in emerging countries.

Lyon (2e) – 30 rue Sainte-Hélène : hôtel de Cuzieu

Les sondages effectués sur la parcelle de l’hôtel de Cuzieu confirment la présence d’une occupation antique au sud de la Presqu’île. Cette occupation, dont les éléments les plus récents sont datés du iiie s. par la céramique, apparaît à plus de trois mètres sous le niveau de la cour, comme pour la grande majorité des découvertes anciennes réalisées à proximité du terrain (cf. contexte archéologique). Cependant, dans les sondages situés à l’arrière de l’hôtel, les niveaux archéologiques sont n..

Mediators and Cytokines in Persistent Allergic Rhinitis and Nonallergic Rhinitis with Eosinophilia Syndrome

Background: Patients with nonallergic rhinitis with eosinophilia syndrome (NARES) show typical symptoms of persistent allergic rhinitis (PAR). The aim of the present study was to compare nasal cytokine patterns between NARES and PAR. Methods: Nasal secretions of 31 patients suffering from NARES, 20 patients with PAR to house dust mite and 21 healthy controls were collected using the cotton wool method and analyzed for interleukin (IL)-1 beta, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17, granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF), interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha), monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-1 beta (MIP-1 beta) by Bio-Plex Cytokine Assay as well as eosinophil cationic protein (ECP) and tryptase by UniCAP-FEIA. Results: NARES and PAR presented elevated levels of tryptase, while ECP was markedly increased solely in NARES compared to both the controls and PAR. Elevated levels of IL-1 beta, IL-17, IFN-gamma, TNF-alpha and MCP-1 were found in NARES compared to the controls as well as PAR. MIP-1 beta was elevated in NARES and PAR, while IL-4, IL-6 and G-CSF showed increased levels in NARES, and IL-5 was elevated in PAR only. Conclusions: In patients with NARES and PAR, eosinophils and mast cells appear to be the pivotal cells of inflammation, reflected by high levels of tryptase and ECP as well as IL-5 and GM-CSF as factors for eosinophil migration and survival. The elevated levels of proinflammatory cytokines in NARES may indicate the chronic, self-perpetuating process of inflammation in NARES which seems to be more pronounced than in PAR. IL-17 might be a factor for neutrophilic infiltration or be responsible for remodeling processes in NARES. Copyright (C) 2012 S. Karger AG, Base

Acting for the Cameras: Performance in the Multi-Camera Sitcom

"The multi-camera sitcom is dying out. It'll go the way of the vaudeville variety show," remarks Janet Kagan, script supervisor on How I Met Your Mother. Steven Levitan, producer of Back To You, offers a different viewpoint: "I grew up watching Dick Van Dyke, Mary Tyler Moore and Cheers...They were incredibly meaningful, and I refuse to believe that human nature has changed that much." These quotes showcase a now-familiar debate: will the single-camera sitcom supplant the multi-camera sitcom? What is it that audiences today, especially in the highly desired 18-34 demographic, supposedly are not responding to in the traditional multi-cam sitcom? While opinions on these questions are voluminous, few, despite the centrality of performance to the reception of any format, have considered performance as a relevant component when comparing sitcom formats and predicting the future of the multi-cam. So I would instead like to ask, how does performance differ between the formats? Might performance have something to do with the ways in which audiences are currently responding to the formats? And if the traditional multi-cam does evolve into a different form or even dies out, what unique performance style might we essentially lose as a result

Formulierung populationsspezifischer Algorithmen zur Bestimmung der Körperfettmasse von Kindern, Jugendlichen und Erwachsenen, basierend auf Feldmethoden mit Air Displacement Plethysmography als Referenz

Die Bestimmung der Körperzusammensetzung ist für die Einschätzung des gesundheitlichen Risikos von Bedeutung. Air Displacement Plethysmography (ADP) ist eine neue, densitometrische Methode, die aufgrund von Luftverdrängung Körpervolumen erfaßt. Über Körpervolumen und -gewicht, werden Dichte und Fettmasse bestimmt. Für Feldstudien werden jedoch transportable, leicht praktikable, kostengünstige Methoden, wie Anthropometrie (z.B. Hautfaltenmessung) und Bioelektrische Impedanzanalyse (BIA), benötigt (sog. „Feldmethoden“). In dieser Arbeit wurden 284 gesunde Kinder, Jugendliche und Erwachsene mit ADP und „Feldmethoden“ untersucht. Ziele waren die Validierung von ADP gegen DEXA und ein Vier-Kompartiment-Modell in einer Subpopulation und die Entwicklung ADP-gestützter Algorithmen für die Bestimmung der Körperfettmasse mit „Feldmethoden“. Wiederholte Messungen an Zylindern und Probanden wiesen eine gute Wiederholbarkeit von ADP auf. Fettmasse nach ADP wurde mit der Fettmasse, berechnet nach populationsunspezifischen Algorithmen, basierend auf „Feldmethoden“, verglichen. Mittlere Unterschiede betrugen bis zu 11 %. Dies bestätigte die Problematik populationsunspezifischer Algorithmen für die Bestimmung der Körperfettmasse. Mit schrittweiser multipler Regression wurden - mit ADP als Referenz - altersspezifische Algorithmen für die Berechnung der fettfreien Masse mit Anthropometrie und BIA formuliert. Nach dem Zwei-Kompartiment-Modell (Körpergewicht = Fettmasse + fettfreie Masse) ist die Bestimmung der Fettmasse möglich. Es bestanden keine systematischen und signifikanten Unterschiede zwischen Fettmasse nach Kieler Algorithmen und ADP
