Recent years have seen the rise of middleboxes, such as NATs, firewalls, or TCP accelerators. Those middleboxes play an important role in today's Internet, including enterprise networks and cellular networks. However, despite their undisputable success in modern network architecture, their actual impact on packets, traffic, and network performance is not that much understood. In this paper, we propose a path impairment oriented middlebox classification that aims at categorizing the initial purpose of a middlebox policy as well as its potential complications. [less ▲]

This thesis explores subjectivities shaped by locomotive disability in the post-apartheid city through an ethnography of ordinary life. Locomotive disability encompasses every limitation of mobility due to an infirmity of the lower limbs. In my discussion, it is conceived as a ‘test’ (épreuve), namely an event that interrupts everyday routines and creates tensions between the responsibilities of different actors’ – people with disabilities, families, the state, etc. These tensions are articulated on various levels. In my discussion, I focus on three of them: the political field that determines a certain type of citizenship, the social networks that constitute the person, and finally the understanding people with disabilities have of their personal history. These levels combine to shape people’s subjectivity, and are analysed in a Foucauldian perspective not just as individuals’ relations with themselves, but also with others and the wider world.

Introduction: The intention of codifying the 14th CBMFC's work with the use of 3CGP (Core Concept Classification in General Practice Family Medicine) appeared during the 21st WONCA World Conference of Family Physicians, when members of the organizing committee of the 14th CBMFC were able to participate in an activity given by Dr Marc Jamoulle on the subject and realized how important it could be to use 3CGP. It consists of using the International Classification of Primary Care (CIAP-2) and the Q-Codes to classify the contents of abstracts submitted to the congress. CBMFCs are large events, which usually receive a substantial number of abstracts. The experience of using 3CGP in an event of this magnitude can have a great impact for the development of the specialty in the country, besides having a pioneering character, contributing for 3CGP to become an international standard in the congresses of family and community medicine. Objectives: Assist the author in the choice of theme; Teaching how to index; Contribute to updating the Q Codes; Manage the congress; Contribute in the management of knowledge in family and community medicine. Method: This is an action research experiment that will consist of the coding of all abstracts submitted to the 14th CBMFC with the use of 3CGP. Authors will be introduced to the classification system by means of an introductory text and should submit their work on the event site using a system that already allows them to perform the encoding of the abstract. The data obtained in this process will be evaluated by members of the organizing committee of the 14th CBMFC, who will be in charge of synthesizing it. [less ▲]

Regenerative design holds great promise for a new era of sustainable and positive impact architecture, sparking considerable interest among architects, building professionals and their clients. Until now there are no green buildings with an overall positive impact on environment and health. In this regard, the professional and scientific potential of regenerative architecture can only be fully realized by the setting a design framework that guides designers during projects design, construction and operation. This book introduces readers to key concepts of circularity in the built environment, highlight best practices, introduce opportunities to create value learn from real cutting edge case studies. In this book, we present a novel framework for regenerative building design that can be applied to future constructions based on professional expertise and exposure, towards healthy, resource efficient and green buildings in the AEC industry. We compare four state of the art buildings to address the critical principles, strategies and steps in the transition from the negative impact reduction architecture to the positive impact regenerative architecture, utilizing life cycle analysis. The case studies analysis and comparison can serve as an inspiring eye opener and provide a vision for architects and building professionals in the fields of high performance buildings, resource centered thinking and regenerative architecture.

Many in vitro or in vivo studies highlighted the potential deleterious effects of phenolic organohalogenated compounds (POHs) on the health, particularly on the thyroid system homeostasis, however few large scale human epidemiological studies have been carried out, especially in Europe. Further studies monitoring the human contamination by POHs, the sources of exposure and the influence of these compounds on thyroid health are still needed. Therefore we determined the concentrations of 16 POHs (pentachlorophenol (PCP), tetrabromobisphenol A (TBBPA), 4 bromophenols (BPs), 3 hydroxy-polybromodiphenylethers (OH-PBDEs) and 7 hydroxy-polychlorobiphenyls (OH-PCBs)) in serum from 274 people aged from 18 to 76 years old living in Liege (Belgium) and the surrounding area. A questionnaire about their alimentary habits, life style and home environment was also administered to the volunteers. The predominant compound measured in the population was PCP (median concentration of 593.0 pg mL−1). 4-OH-CB 107, 4-OH-CB 146 and 4-OH-CB 187 were detected in all samples and contributed for 75% of the sum of OH-PCBs (ΣOH-PCBs). The median measured in our population for ΣOH-PCBs was 143.7 pg mL−1. TBBPA and 2,4,6-tribromophenol were detected in 31% and 63.8% of the samples respectively while the detection frequency observed for the other BPs and the OH-PBDEs was close to zero. We computed multivariate regression models in order to assess the influence of demographic and lifestyle parameters on the PCP and ΣOH-PCBs contamination levels. Significant correlation was found between the PCP concentration and sex, smoker status, sea fish consumption and level of education, although the model seemed to be a poor (R2 = 0.14) predictor of the PCP concentration. The model computed for ΣOHPCBs was more explanatory (R2 = 0.61) and involved age, BMI and sea fish consumption. Finally, we assessed the parameters affecting the ΣOH-PCBs/ΣPCBs ratio. The model proposed involved age, BMI, smoker status and parent PCB level, and explained 41% of the variability of the ΣOH-PCBs/ΣPCBs ratio. [less ▲]

We show by numerical simulations a fundamental gain in contrast when combining coherently monochromatic light from two adaptive optics (AO) telescopes instead of using a single stand-alone AO telescope, assuming efficient control and acquisition systems at high speed. A contrast gain map is defined as the normalized point spread functions (PSFs) ratio of a single Large Binocular Telescope (LBT) aperture over the dual Large Binocular Telescope Interferometer (LBTI) aperture in Fizeau mode. The global gain averaged across the AO-corrected field of view is improved by a factor of 2 in contrast in long exposures and by a factor of 10 in contrast in short exposures (i.e. in exposures, respectively, longer or shorter than the coherence time). The fringed speckle halo in short exposures contains not only high-angular resolution information, as stated by speckle imaging and speckle interferometry, but also high-contrast imaging information. A high-gain zone is further produced in the valleys of the PSF formed by the dark Airy rings and/or the dark fringes. Earth rotation allows us to exploit various areas in the contrast gain map. A huge-contrast gain in narrow zones can be achieved when both a dark fringe and a dark ring overlap on to an exoplanet. Compared to a single 8-m LBT aperture, the 23-m LBTI Fizeau imager can provide a gain in sensitivity (by a factor of 4), a gain in angular resolution (by a factor of 3) and, as well, a gain in raw contrast (by a factor of 2-1000 varying over the AO-corrected field of view).

El siguiente texto hace parte de un reciente libro que Jacques Dubois tituló Figuras del deseo. Por una crítica amorosa (Les Impressions Nouvelles, 2011). A Dubois lo conocemos hoy en día como fundador del famoso Grupo μ, al que le debemos la Retórica general (1970), como autor en 1978 de una obra fundamental para la sociología de la literatura, La institución de la literatura, y como especialista de Georges Simenon y de la literatura francesa de los siglos xix y xx. En su último libro, el científico riguroso cede la palabra al lector ferviente, crítico-amoroso desconcertante y lleno de imaginación, pero que no deja de sorprendernos con una nueva propuesta metodológica que bien podría calificarse como «una lectura activa del deseo». ¿En qué consiste esta «crítica amorosa»? ¿Cómo definirla? Se trata, ante todo, de una lectura en la que el crítico, animado por su deseo, rehúsa desempeñar un rol pasivo para intervenir así en la narración que le da vida a los personajes, dejando al mismo tiempo que estos se inmiscuyan en el relato de su propia vida. ¡Y su intervención resulta reveladora! Habitado por el mundo de la novela, el crítico «activo e imaginativo» que es Dubois termina por colaborar con el novelista, o por lo menos con el narrador, para desentrañar los posibles significados del universo narrativo, pero también para encontrar allí posibles fisuras en las que pueda deslizar su potente acción creadora, abriendo así «la perspectiva de una novela que pudo haber sido otra cosa de lo que es» (Dubois, 2011, p. 8). Nos encontramos pues frente a una «lectura activa» que se erige entre las exigencias de significación impuestas por el texto y el deseo que este genera de prolongarlo, de transformarlo. Los vectores de dicho deseo serán los personajes mismos, que el crítico-amoroso acompaña y hace brillar en todas sus potencialidades significativas, dotándolos de una vida segunda. De ahí que, como lo señala el mismo Dubois, «la lectura activa, en su versión amorosa, adquiera derechos sobre la ficción» (p. 10) sin que esto signifique por lo tanto que se traicione el texto, pues se trata más bien de hacerlo explotar. Y es en esta explosión que surge la pregunta, latente en la nueva propuesta que nos hace Dubois, por el acto de la lectura: «¿Qué significa amar un personaje?» ¿Cómo se desarrolla una lectura crítica y creadora? La respuesta nos llevará a lo que podríamos llamar desde ya una lectura social del deseo en la que se opera «un deslizamiento progresivo del placer y de lo sexual hacia lo social», como lo muestra el autor en el siguiente capítulo.

This paper studies the links between non-renewable and intermittent renewable energy sources in the production of electricity. Using U.S. state-level data from 1998 to 2015, we find that the relationship between the price of natural gas and investments in solar and wind capacity is non-linear and can be represented by an inverted U-shape. Hence, for relatively low natural gas prices, the two modes of production are substitutes. After a price threshold is reached, the two are complementary. A theoretical explanation argues that this stylized fact is the result of a trade-off between two characteristics of these modes of production: the high degree of flexibility of electricity production using natural gas as an input and the low marginal cost of renewable energy sources.

Our essay aims at continuing the work of Jacques Fontanille, who developed a Semiotics of Practice next to a Semiotics of Text. This work, and especially Pratiques sémiotiques (2008), takes up a problem already formulated by Jean-Marie Floch in the article « Êtes-vous arpenteurs ou somnambules ? L’élaboration d’une typologie comportementale des voyageurs du métro » (1990). We will initially retrace the debate about the epistemological relationship between text and practice, outlining the forms of enunciative praxis. Secondly, we propose the concept of we will consider the visualization that we call ‘notation’: this analytical form of mediation between text and practice does not have the same status of in-vivo textualisations, but it works like an ex-post reconstruction which highlights the main gestures and exchanges while performing their grammaticalization. A more general aim of this essay is an enquiry into the legitimate objects of textual semiotics: what are the objects that it can analyze without betraying its principle of immanence, but also without being unable to analyze practice [less ▲]

Background: Platelets have been involved in both surveillance and host defense against severe infection. To date, whether platelet phenotype or other hemostasis components could be associated with predisposition to sepsis in critical illness remains unknown. The aim of this work was to identify platelet markers that could predict sepsis occurrence in critically ill injured patients. Results: This single-center, prospective, observational, 7-month study was based on a cohort of 99 non-infected adult patients admitted to ICUs for elective cardiac surgery, trauma, acute brain injury and post-operative prolonged ventilation and followed up during ICU stay. Clinical characteristics and severity score (SOFA) were recorded on admission. Platelet activation markers, including fibrinogen binding to platelets, platelet membrane P-selectin expression, plasma soluble CD40L, and platelet-leukocytes aggregates were assayed by flow cytometry at admission and 48h later, and also at the time of sepsis diagnosis (Sepsis-3 criteria) and 7 days later for sepsis patients. Hospitalization data and outcomes were also recorded. Of the 99 patients, 19 developed sepsis after a median time of 5 days. SOFA at admission was higher; their levels of fibrinogen binding to platelets (platelet-Fg) and of D-dimers were significantly increased compared to the other patients. Levels 48h after ICU admission were no longer significant. Platelet-Fg % was an independent predictor of sepsis (P = 0.030). By ROC curve analysis cutoff points for SOFA (AUC=0.85) and Platelet-Fg (AUC=0.75) were 8 and 50%, respectively. The prior risk of sepsis (19%) increased to 50% when SOFA was above 8, to 46% when Platelet-Fg was above 50%, and to 87% when both SOFA and Platelet-Fg were above their cutoff values. By contrast, when the two parameters were below their cutoffs, the risk of sepsis was negligible (3.8%). Patients with sepsis had longer ICU and hospital stays and higher death rate. Conclusion: In addition to SOFA, platelet-bound fibrinogen levels assayed by flow cytometry within 24h of ICU admission help identifying critically ill patients at risk of developing sepsis.

Fire following earthquake (FFE), a cascading multi-hazard event, can cause major social and economical losses in a community. In this paper, two existing post-earthquake fire ignition models that are implemented in Geographic Information System (GIS) based platforms, Hazus and MAEViz/Ergo, are reviewed. The two platforms and their FFE modules have been studied for suitability in community resiliency evaluations. Based on the shortcomings in the existing literature, a new post-earthquake fire ignition model is proposed using historical FFE data and a probabilistic formulation. The procedure to create the database for the model using GIS-based tools is explained. The proposed model provides the probability of ignition at both census tract scale and individual buildings, and can be used to identify areas of a community with high risk of fire ignitions after an earthquake. The model also provides a breakdown of ignitions in different building types. Finally, the model is implemented in MAEViz/Ergo to demonstrate its application in a GIS-based software. [less ▲]
