Formal Experimentation and Time Travel As a Reconceptualization Strategy in Anthony Joseph’s The African Origins of Ufos
Creators: name: Elia, Adriano
Publisher: name: Iperstoria
Year: 2019

description: Anthony Joseph’s groundbreaking novel The African Origins of UFOs (2006) is a challenging example of Afrofuturist speculative fiction. Divided into three interweaving sections set in space in the future, on land in the present and in water in the past, this eccentric novel draws on time travel as a means to reconsider notions of race, identity, exile and collective memory. Charged with innumerable allusions, Joseph’s experimental style, blending poetry and prose, is an ideal counterpart to the richness and variety of content, whereby the conflation of past, present and future brings about a reconceptualization of hegemonic discourses on the black diaspora.

“Black Space Is Time:” Intermediality, Narrative, and Community in Michael Ondaatje
Creators: name: Fusco, Serena
Publisher: name: Iperstoria
Year: 2019

description: This essay proposes to explore some aspects and implications of intermediality in three novels by Michael Ondaatje: In the Skin of a Lion (1987), The English Patient (1992), and Divisadero (2007); more specifically, my focus is on the exchange involving literature and the two visual codes of painting and photography. I especially underline two possible configurations of a reiterated light/darkness interplay which traverses Ondaatje’s oeuvre. On the one hand, light and darkness mirror each other as extreme poles which blend, in concrete, in infinite shades of grey, mirroring a photographic process; on the other hand, darkness surrounds, in a Caravaggesque fashion, pools of light illuminating fleeting moments in time; the latter configuration is also, to an extent, ante litteram photographic. What should be crucially emphasized in reading Ondaatje is the complex temporal quality of the dark spaces inevitably surrounding the moments of light. In a meta-literary and meta-narrative fashion, intermedial gestures appear to be necessary to the very possibility of narration, to its onward movement in space and time; at the same time, these gestures always entail a level of “fecund invisibility”. In Ondaatje’s literary narrative, the possibility, for various beings (human as well as nonhuman), events, and medial codes to exist next to each other, without one forcefully assimilating the other, is predicated on a Benjaminian kind of historical materialism in which darkness is the indispensable space/time wherein the actions of the present resonate and acquire (historical) meaning.

The Tragedy That Dare Not Speak Its Name: A Reading of Arthur Kopit’s Oh Dad, Poor Dad, Mamma’s Hung You in the Closet and I’m Feeling So Sad
Creators: name: Iuliano, Fiorenzo
Publisher: name: Iperstoria
Year: 2019

description: Arthur Kopit’s Oh Dad, Poor Dad, Mamma’s Hung You in the Closet and I’m Feelin’ So Sad (1962) has received so far limited scholarly attention, and the studies on the play have mostly focused on the text’s psychoanalytic overtones. The play features the relationship between its bizarre protagonist, Mme. Rosepettle, and her son Jonathan, who is completely subjected to her despotic and repressive will. The Oedipal complex foreshadowed in the play, however, does not exhaust the complex matter of the text, whose references to Cuba and South American countries strongly ask for a political reading. This article paper, consequently, reads the play as instancing the impossibility of an American national tragedy in the Cold War era. The play, in fact, assaults the US chauvinist and anti-communist ideology of the 1950s, and displays its consequences upon individuals and society. The post-war paranoia is acted out in the hidden corpse of Mr. Rosepettle, which Mme. Rosepettle preserves in her closet. The corpse, as a fetishistic object (for Mme. Rosepettle) and a source of fear and anxiety (for Jonathan), signals the impossibility, for the US of the time, to identify with tangible models and positive values (despite the materialistic ethos of the culture of the 1950s, as witness Mme. Rosepettle’s obsessive need for fun and self-gratification). On the contrary, only death and loss, as overhanging threats and macabre horizon of collective expectation, paradoxically provide the nation with a unifying sense of identification. The Cold War, as a conflict that was never directly waged or fought, but nevertheless informed American identity, politics and culture, thus functions as the ‘void center’ of the play. By instancing the lack (or the loss) as a site of affirmative identification, this fantasmatic war is what turns the play into an impossible tragedy.

description: Dies ist ein Protokoll für ein systematisches Review: Studienprotokoll – Medikation und Lebenssituation im Alter: Alzheimer Demenz Version 1 – 30.06.2017: In einer zunehmend älter werdenden Gesellschaft wird die gesundheitliche Versorgung der Bevölkerung in Zukunft vor neue Herausforderungen gestellt werden, denn das Auftreten von Krankheiten, wie beispielsweise der Alzheimer Demenz, ist stark mit einem höheren Lebensalter assoziiert. In bisherigen systematischen Übersichtsarbeiten zur Pharmakotherapie der Alzheimer Demenz wurde allerdings nicht speziell auf die Rolle von funktionell beeinträchtigten Patienten (sog. „frail elderly“) eingegangen, so dass bisher keine Bewertung der Evidenz für die Anwendung in diesem Patientenkollektiv besteht. Auch war beispielsweise das Durchschnittsalter der Studienpopulationen meist niedriger als das der Referenzpopulation. Daher stellt sich die Frage, inwiefern eine Pharmakotherapie bei Alzheimer Demenz bei funktionell beeinträchtigten Patienten („frail elderly“) evidenzbasiert möglich ist. Ziel der Arbeit ist die Erstellung eines systematischen Reviews und wenn möglich einer Meta-Analyse mit der Frage, inwiefern oder ob überhaupt eine evidenzbasierte Pharmakotherapie bei Alzheimer Demenz bei funktionell Beeinträchtigten („frail elderly“), basierend auf den bisherigen RCTs zur Pharmakotherapie bei Alzheimer Demenz, möglich ist.
Cultivating Effective Communication in Healthcare: The Case of Q&A Websites
Creators: name: Maglie, Rosita
Publisher: name: Iperstoria
Year: 2019

description: Question-and-answer (QA) websites in health domains have become virtual places where information and advice can be sought and obtained. Such virtual encounters with different linguistic communities have increasingly become the norm for young people who rarely undergo regular medical examinations. For this category of people, the Internet is the electronic gateway to confidential advice and information on health issues. In this regard, QA websites, such as Kinsey Confidential, Go Ask Alice!, and The Teenage Health Freak offer a unique and novel vantage point from which to survey both how young people think and talk about their own health, and how health professionals engage in new modes of communication to provide health advice and information. In order to scrutinize adolescents and health professionals’ communicative behavior, this study not only has the potential to provide linguistic data for the expanding field of research in computer-mediated communication (CMC), but it could also prove meaningful to health professionals themselves and policymakers. It adopts a corpus-based approach to discourse analysis to provide quantitative evidence of the occurrence of qualitative patterns of discourse and language use in Kinsey Confidential, Go Ask Alice! and The Teenage Health Freak corpora, particularly in QA posts on health issues such as birth control and pregnancy, sexually transmitted infections, and gender and sexual orientation. Findings show how unfamiliar young people still are with regards to sexual health. While some misconceptions and prejudices can be ascribed to popular myths and rumors, much of this lack of knowledge is due to a scarcity of successful educational interventions and policy initiatives. For this reason, investigating how healthcare providers interact with adolescents online can lead us to new ways of thinking about successful relationships between patients and healthcare providers, and helps us prepare future educational models that incorporate online communication and consider how young people think about and participate in these language communities.

description: Human zinc deficiency increases susceptibility to bacterial infection. Although zinc supplementation therapies can reduce the impact of disease, the molecular basis for protection remains unclear. Streptococcus pneumoniae is a major cause of bacterial pneumonia, which is prevalent in regions of zinc deficiency. We report that dietary zinc levels dictate the outcome of S. pneumoniae infection in a murine model. Dietary zinc restriction impacts murine tissue zinc levels with distribution post-infection altered, and S. pneumoniae virulence and infection enhanced. Although the activation and infiltration of murine phagocytic cells was not affected by zinc restriction, their efficacy of bacterial control was compromised. S. pneumoniae was shown to be highly sensitive to zinc intoxication, with this process impaired in zinc restricted mice and isolated phagocytic cells. Collectively, these data show how dietary zinc deficiency increases sensitivity to S. pneumoniae infection while revealing a role for zinc as a component of host antimicrobial defences.

description: Leishmaniasis is a severe public health problem, caused by the protozoan Leishmania. This parasite has two developmental forms, extracellular promastigote in the insect vector and intracellular amastigote in the mammalian host where it resides inside the phagolysosome of macrophages. Little is known about the virulence factors that regulate host-pathogen interactions and particularly host signalling subversion. All the proteomes of Leishmania extracellular vesicles identified the presence of Leishmania casein kinase 1 (L-CK1.2), a signalling kinase. L-CK1.2 is essential for parasite survival and thus might be essential for host subversion. To get insights into the functions of L-CK1.2 in the macrophage, the systematic identification of its host substrates is crucial, we thus developed an easy method to identify substrates, combining phosphatase treatment, in vitro kinase assay and Stable Isotope Labelling with Amino acids in Cell (SILAC) culture-based mass spectrometry. Implementing this approach, we identified 225 host substrates as well as a potential novel phosphorylation motif for CK1. We confirmed experimentally the enrichment of our substratome in bona fide L-CK1.2 substrates and showed they were also phosphorylated by human CK1δ. L-CK1.2 substratome is enriched in biological processes such as “viral and symbiotic interaction,” “actin cytoskeleton organisation” and “apoptosis,” which are consistent with the host pathways modified by Leishmania upon infection, suggesting that L-CK1.2 might be the missing link. Overall, our results generate important mechanistic insights into the signalling of host subversion by these parasites and other microbial pathogens adapted for intracellular survival.
Il gangster movie postmoderno e la decostruzione della mascolinità tradizionale in Terapia e pallottole (1999), Un boss sotto stress (2002) e Cosa fare a Denver quando sei morto (1995)
Creators: name: Accattoli, Nicola
Publisher: name: Iperstoria
Year: 2019

description: This paper focuses on the deconstruction process Italian American masculinity has sustained for the last three decades in American cinema and television. For this essay, we will take into account three underrated movies: Things to Do in Denver When You’re Dead (1995), Analyze This (1999) and Analyze That (2002). After a brief theoretical introduction, intended to present a new model of masculinity called “mascolinità contemperata”, the essay will proceed with the analysis of the texts, aimed to show how Italian American masculinity in movies has changed, adapting to a social reality where gender equality, although far from being fully achieved, is slowly becoming a reality. In this scenario, the Hegemonic Masculinity model theorized by Raewyn Connel is no longer viable, hence the shift towards “mascolinità contemperata”. Finally, by examining Analyze That in detail, it will be made clear that another deconstruction process, simultaneous to that of the masculinity, is taking place: that of the gangster movie as a genre.

description: Abstracts Issue 10 – Fall/Winter 2017 in the Cold War era. The play, in fact, assaults the US chauvinist and anti-communist ideology of the 1950s, and displays its consequences upon individuals and society. The post-war paranoia is acted out in the hidden corpse of Mr. Rosepettle, which Mme. Rosepettle preserves in her closet. The corpse, as a fetishistic object (for Mme.

By instancing the lack (or the loss) as a site of affirmative identification, this fantasmatic war is what turns the play into an impossible tragedy. Pireddu, Nicoletta DECOLONIZZARE L’IDENTITÀ: ITALIA E AMERICA ALLO SPECCHIO As it is often the case with countries where mass immigration is intense, ethnicity is one of the most evident expressions of identitary politics in the United States, and the community of Italian immigrants is undoubtedly characterized by a strong sense of ethnic identity. In fact, Italian American culture had to manage conflictual needs, and still needs to do so; on the one hand the search for a sense of belonging and participation to the adopted culture, on the other the struggle against mostly negative or diminishing stereotypes. Starting from recent and significant contributions to the debate, the essay analyzes the limits of categorizations, and calls for multiple perspectives in conceptualizing and representing Italian American culture in the context of diaspora and transcontinental immigration studies. Migration emerges thus as a model for mobility and flexibility, as a reinvention of the self and as a way of negotiating the other.

description: Imaging radars are usually realized fully coherently. However, the distribution of one common radio frequency signal to all transmit and receive paths requires a high degree of hardware complexity. In order to reduce the hardware effort significantly, a novel phase synchronization method for incoherent and quasi-coherent frequency-modulated continuous-wave (FMCW) imaging radars with individual signal synthesis per channel is presented. The quasi-coherent setup uses one common oscillator for all frequency synthesizers. It is shown that in the case of the quasi-coherent system, only a phase difference between the calibration and the measurement has to be corrected to achieve coherence. In comparison, an incoherent system causes additional time, frequency, and FMCW ramp slope errors due to the different behavior of the oscillators. In order to achieve phase coherence and to correct the error sources, a calibration-based method using a defined signal path as part of the radar system is proposed. The imaging radar used for verification of the theory consists of individual single-channel radar monolithic microwave integrated circuits (MMICs) at 160 GHz; each MMIC fed by an individual frequency synthesizer. As shown by measurements, it is possible to achieve phase coherence for both system approaches and to perform angle estimation.

Ciò nondimeno, molte aree del mondo, Italia inclusa, hanno sviluppato storicamente differenti pratiche di (e contro l’)occupazione ben prima del cosiddetto movimento #Occupy.

description: International relationships and migratory movements, particularly towards European countries, have a crucial importance in the process leading to the formation of society. The intensification of the former and the escalation of the latter have been playing a fundamental role in the course that led to the creaking of the long standing idea of nation-state and the consequent weakening of social cohesion. The change of the migratory configuration that characterized the past few decades, with the increasing number of undocumented migrants and refugees fleeing from areas of conflicts, led European countries to the necessity of enacting new systems and processes for granting political, economic, and civil rights to people involved in migratory movements.

description: Studies of rodent models of Alzheimer's disease (AD) and of human tissues suggest that the retinal changes that occur in AD, including the accumulation of amyloid beta (Aβ), may serve as surrogate markers of brain Aβ levels. As Aβ has a wavelength-dependent effect on light scatter, we investigate the potential for in vivo retinal hyperspectral imaging to serve as a biomarker of brain Aβ. Significant differences in the retinal reflectance spectra are found between individuals with high Aβ burden on brain PET imaging and mild cognitive impairment (n = 15), and age-matched PET-negative controls (n = 20). Retinal imaging scores are correlated with brain Aβ loads. The findings are validated in an independent cohort, using a second hyperspectral camera. A similar spectral difference is found between control and 5xFAD transgenic mice that accumulate Aβ in the brain and retina. These findings indicate that retinal hyperspectral imaging may predict brain Aβ load.

description: Ecological Momentary Assessments (EMA) deliver insights on how patients perceive tinnitus at different times and how they are affected by it. Moving to the next level, an mHealth app can support users more directly by predicting a user's next EMA and recommending personalized services based on these predictions. In this study, we analyzed the data of 21 users who were exposed to an mHealth app with non-personalized recommendations, and we investigate ways of predicting the next vector of EMA answers. We studied the potential of entity-centric predictors that learn for each user separately and neighborhood-based predictors that learn for each user separately but take also similar users into account, and we compared them to a predictor that learns from all past EMA indiscriminately, without considering which user delivered which data, i.e., to a “global model.” Since users were exposed to two versions of the non-personalized recommendations app, we employed a Contextual Multi-Armed Bandit (CMAB), which chooses the best predictor for each user at each time point, taking each user's group into account. Our analysis showed that the combination of predictors into a CMAB achieves good performance throughout, since the global model was chosen at early time points and for users with few data, while the entity-centric, i.e., user-specific, predictors were used whenever the user had delivered enough data—the CMAB chose itself when the data were “enough.” This flexible setting delivered insights on how user behavior can be predicted for personalization, as well as insights on the specific mHealth data. Our main findings are that for EMA prediction the entity-centric predictors should be preferred over a user-insensitive global model and that the choice of EMA items should be further investigated because some items are answered more rarely than others. Albeit our CMAB-based prediction workflow is robust to differences in exposition and interaction intensity, experimentators that design studies with mHealth apps should be prepared to quantify and closely monitor differences in the intensity of user-app interaction, since users with many interactions may have a disproportionate influence on global models.

description: Background: This study examines social disparities across neighbourhood levels of income, education and employment in relation to overall injury hospital separations in the province of British Columbia, Canada. Further, the study examines the relationships of social disparities to a set of three injury prevention priorities in British Columbia, namely, transport (motor vehicle occupant, pedestrian and cyclist), falls among older adults, and youth self-harm. The goal being to better understand area-based injury incidence with a view to precision prevention initiatives, particularly for more vulnerable populations. Methods: Acute hospital separations from the Discharge Abstract Database were identified for all causes of injury and the three BC injury prevention priorities for the period April 1, 2009 to March 31, 2014, inclusive. An ecological approach was applied where each hospital separation case was attributed with the income, education and employment level according to the injured individual’s area of residence, derived from the 2011 CensusPlus data. Results: Injury hospital separation data were available for 191 Forward Sortation Areas in BC. Between April 1, 2009 and March 31, 2014, there was a total of 177,861 injury-related hospital separations, averaging 35,572 hospital separations per year and an annual rate of 779 injury hospital separations per 100,000 population. Injury hospital separation rates varied with the measured neighbourhood area socioeconomic status variables. Injury hospital separation rates demonstrated an inverse relationship with neighbourhood levels of income and education. Neighbourhood area socioeconomic status differences were also associated with the injury hospital separation rates for falls among older adults, motor vehicle crashes involving motor vehicle occupants, pedestrians, cyclists and young drivers, and youth self-harm. Conclusions: The study results show that neighbourhood levels of income, education and employment are associated with the risk of injury hospital separation. In particular, low education levels in FSAs was associated with increased risk of injury hospital separation, mainly for motor vehicle occupants, pedestrians, young drivers, and youth self-harm. The results of this study provide useful information for implementing injury prevention initiatives and interventions in BC to align with the provincial public health system and road safety strategy goals, particularly for identified priorities.
Speckle noise reduction of synthetic aperture radar imagery using Kalman filters.

description: Synthetic aperture radar (SAR) imagery is gaining increased usage as more systems become available and more applications are being developed. An "unfortunate" problem with SAR imagery is the high level of noise, often called speckle. The speckle effects reduce the utility of SAR imagery a great deal. This thesis will address the causes of speckle and many of the current methods that are used to reduce the speckle noise. Kalman filtering methods will then be adapted for use on SAR imagery taking into account the special properties of this type of filter and images.

description: Open Science involves using new approaches to scientific practice that makes the outputs of research freely available under terms that enable reuse, redistribution and reproduction.  Empirical research using software involves researchers identifying a problem, gathering data, building a model or writing analysis software, possibly simulating the physical system, analysing results and producing research articles. There are many topics in Open Science that could help a researcher to his or her research more open.  However, particularly for those new to Open Science, it can be difficult to get started or even to organise and approach or strategy.  This discussion article proposes a set of Levels of Open Science for this area and is aimed at contributing to this emerging debate.

description: Today's global economy requires businesses to expand their processes beyond organizational domains to integrate business partners and collaborators. SOA through Web services is emerging as a framework for bridging heterogeneous business systems over the Internet. Unfortunately it is still limited by many of the constraints of the legacy applications: procedural interaction, data polling and strong coupling of applications. Event-driven systems like publish/subscribe on the other hand provide a flexible interaction pattern that does not require rigid transport or communication protocol. Robust B2B process integration requires a framework that supports enterprise and Internet scale data sharing, point-to-point, push interaction as well as publish/subscribe broadcast based interaction. In our thesis, we accomplish this through a framework the views a B2B network as a streaming database and uses declarative policies to describe data sharing based on an SOA publish/subscribe infrastructure. The key contribution of our thesis is to define a flexible policy approach for describing streaming data. A Palliative Severe Pain Management scenario was implemented to evaluate our framework against BPI frameworks.

Applied Theatre e teatro sociale. L'estetica del teatro fuori dal teatro
Creators: name: Iacobone, Paola
Publisher: name: Iperstoria
Year: 2019
Subjects: Theatre studies; applied theatre

description: Il teatro sociale, o applied theatre, rappresenta una forma teatrale che utilizza l’arte come strumento didattico, di redenzione, di sostegno e a volte di cura, sostenendo, sostituendo, contrapponendosi o arricchendo il lavoro di ospedali, scuole, campi profughi, centri diurni, carceri e molte altre realtà al di fuori del teatro ufficiale. La caratteristica del teatro quale forma artistica viva, dialogica, capace di stimolare gli istinti più profondi e mettere in gioco le convinzioni più radicate, s colloca al centro nelle sessioni e negli spettacoli di un teatro che ha scelto di tornare all’essenza, di liberarsi del professionismo ma non della professionalità, per giocare ad essere altro.

description: Interview with Ian Bruno, Stuart Chalk, Martin Hicks, Carsten Kettner, Leah McEwen, recorded at the BEILSTEIN OPEN SCIENCE SYMPOSIUM (22 – 24 May 2017). At the end of the Beilstein-Institut’s symposium on Open Science in Chemistry, Carsten Kettner interviews the panel of Ian Bruno, Stuart Chalk, Martin Hicks and Leah McEwen on themes and perspectives for open science in chemistry that came out of the meeting. Listen to the answers on the following themes: 1) Open science and chemistry. Is it a contradiction? 2) Are chemists behind other disciplines, because for example in physics or biology, the projects are often bigger and require collaboration? In chemistry, the projects are often sufficient for one group to carry out. 3) What is the perspective for the chemistry lab of the future? The panel, each an expert from a different area of communicating chemical science information, gave some fascinating insights on how chemistry research might move to become more open, with more collaboration, and a higher degree of digitization in the laboratory. It will be interesting to see how many of these predictions come true.
The effect of nonnormal ability distributions on IRT parameter estimation using full-information and limited-information methods.

description: The relationship between nonlinear factor analysis (FA) models and Item Response Theory (IRT) models has been well established. Furthermore, in terms of modern measurement theory, the use of nonlinear FA models to describe item-trait relationships is currently becoming more popular and may offer some statistical and/or computational advantages in the analysis of item response data. Both limited-information (LI) and full-information (FI) nonlinear FA models can be used to derive the familiar IRT parameter estimates. In general, the two approaches (LI and FI) are distinguished simply by the extent to which they use information in the data matrix of examinee (subject) responses. The focus of this study was to compare the accuracy and efficiency of IRT parameter estimates (i.e., item difficulty, item discrimination) using both LI and FI nonlinear FA models. A Monte Carlo study was employed to investigate the precision and stability of parameter estimates in situations where (a) the manifest variables (test items) are binary and there is a single underlying normally distributed latent variable and (b) the manifest variables are binary and there is a single underlying latent variable that is not normally distributed. In addition, parameter recovery was explored under various simulated test lengths (number of items) and sample sizes (number of examinees). The results of the study suggest that, for conditions involving a normally distributed latent variable, the limited-information approach incorporated in the NOHARM computer program generally provides more accurate and stable parameter estimates than the theoretically preferred FI estimator incorporated in the TESTFACT computer program. For situations involving a nonnormal distribution of the latent trait, or ability, FI estimation provided a marginally better calibration of the 2-parameter logistic response model. Both estimators were, however, prone to producing item values that were outside of feasible ranges, resulting in poor goodness-of-fit of the estimates. Furthermore, based on the conditions modelled in the study, neither the sample size, the test length, nor the sample size/test length ratio were important in terms of explaining between-program differences in the recovery of the item parameters.

description: Interview with Klaus Tochtermann, Leibniz Information Centre for Economics, Kiel, Germany, recorded at the BEILSTEIN OPEN SCIENCE SYMPOSIUM (22 – 24 May 2017). Klaus Tochtermann discusses the European Science Cloud (EOSC) with Carsten Kettner. He describes the concept for the ESOC which is planned to connect current and future research data centers with one another in an eco-system of infrastructures. Also discussed are the standards necessary to make such an eco-system function: standards for metadata, standards for APIs and standards for authentication. He stressed the need for scientists to make their data FAIR (findable, accessible, interoperable and reusable), to support cross-disciplinary research and re-use. In the EOSC all data should be FAIR. Klaus mentions that in the opinion of the high level expert group on EOSC, about 80% of the reasons that scientists do not share data are cultural, mainly due to the lack of sufficient incentives.
An increase in the frequency of hprt mutant T lymphocytes in the peripheral blood, synovial fluid, and synovial tissue of rheumatoid arthritis patients.

description: I used the hypoxanthine guanine phosphoribosyl transferase (hprt) clonal assay to determine the in vivo frequency of mutant T cells (FMC) from the peripheral blood, synovial fluid, and synovial tissue of rheumatoid arthritis (RA) patients and controls. The results demonstrate that there is an increased FMC in the peripheral blood of RA patients compared to controls. There was also a significant elevation in the corrected FMC (cFMC), which takes in to account the cloning efficiency of the T cells, in the peripheral blood of RA patients compared to controls. There is an elevated FMC and cFMC in synovial fluid of RA patients compared to the peripheral blood of controls. However. the FMC and cFMC from the peripheral blood of unselected RA patients from the outpatient clinic is not significantly different than from the synovial fluid of RA patients suggesting that the synovial fluid does not contain the necessary mitogenic and mutagenic factors to induce T cell genetic damage. The FMC and cFMC from RA and osteoarthritis (OA) synovium is approximately ten fold greater than the FMC and cFMC from the peripheral blood of the same patients which suggests that the mitogenic and genotoxic environment of the inflamed synovium is capable of inducing T cell mutations. There was no significant difference in the cloning efficiency of T cells (CE), FMC, and cFMC from the peripheral blood of RA patients with 'active' or 'inactive' disease. No correlation between the cFMC from the peripheral blood of RA patients and clinical disease parameters and patient medication was found. (Abstract shortened by UMI.)
Dynamics-based control of a mobile robot with non-holonomic constraints.

description: The development of a planetary rover for use on the moon or on Mars has generated further interest in autonomous vehicles which are capable of moving through a complicated terrain with minimal supervision. One approach for enhancing autonomy is a dynamics based controller which could ensure motion stability and avoid catastrophic events. This approach allows the monitoring of wheel to ground contact forces which is helpful in avoiding slippage and tipping. As a prelude to more sophisticated tests in a three dimensional environment with random obstacles, a tricycle configuration mobile robot has been built and used to verify the performance of dynamics based control on a flat surface. This controller works by taking into consideration the forces involved in moving the vehicle and therefore can produce better control than controllers which consider only kinematics or simplified dynamics of the system. The work presented here describes the controller of a mobile robot based on dynamics and discusses design aspects of the robot used in this type of system. (Abstract shortened by UMI.)
